And to help me do that, is the gang gang right here in the studio, starting with our very own star, C.J.C. as we call her. Sarseni. Hey, how are you? How are you? Okay. Sarseni. Hey, how are you? Hi. We're down our dialettes. We are back on Thursday.  Yeah. And tuning in, we'll be back in a few minutes. This is the remote. Yes. Hi, Guzwin. Remote. I don't know what I'm saying. Are we together? What do I do with my camera? Are we together? Because I'm a cutie. A cutie. So ladies and gentlemen, as we always say, the mighty room is officially open. To give all the remote now to Neuma. Yeah. Now, welcome to the show. Come on, Karina. We're going to have a great time. Let us know where you're watching from. And at the end of the show, we'll be sending some love, some shout outs your way. Right? Now, on to our first story. I'm the Friday night. Umulwa Omaniala is all the fastest man in Africa and eighth globally after breaking the continent, 100 meters record. 25-year-old Ren, 9.77 seconds at Saturday's Kepkeino Classic meeting at Kasarani Stadium in Nairobi to break the mark of 9.85 seconds set by South Africa's Akkani Simbilia in July. Now, while being hindered at Toyota Harrier to celebrate his win, courtesy of Odi Betz, the sprinter, disclosed that he owes his success to his girlfriend, who stood by him when he was broke. He said his girlfriend would pay all the bills, including rent, and now he will buy her whatever she needs. A statement that has sparked conversation on social media. That's amazing, right? Now you've got to come with me. What? What? I mean, I don't know. I was going to start with Jaycee, but then I'm just saying, you know what? Jaycee missed your last speech. I know you have a lot to say. So please, kindly, go right ahead. He could have killed Jaycee on the same day. You know, congratulations, but then, literally, the fastest man in Africa comes from Kenya. Yes. The fastest man in the world comes from Kenya. I don't take it for granted. We were never in the short races. Long distance. Long distances. There were no obstacles. On that note, as you said, there are some people who approached what they were international and stuff. I think they trained athletes. I don't know. Welcome, talk. It's good you believe in yourself, but Kenya, you'll never run short. You can't always just focus on the marathon, not a hundred meters. Look at him now. I was actually hearing him telling his story and sometimes you would think, he broke two records in a day in one of his experiences. Within three months, he broke a record of 10.01 all the way to 9.77. If you watch it, you'll know. One second. You'll know. You'll know a lot. One second. If in that race... I can't keep talking. What is it called? The Ineos. Ineos. Second. That is under two hours. Imagine. 9.77. He's going for bold as we speak. As he said. Right now he's number 8. He's going for bold. Number 9. Awanyala. You guys. Awanyala. Come on, let's see. Let's talk about a different angle. Because Awanyala acknowledged this girlfriend for the last six months, and no competition. He didn't have any money. He didn't have any source of income. The girlfriend took care of him and the entire family. She was putting the bills, paying rent, and literally everything.  Now that I have money, I'm going to take care of you. What do we think? He's the first man to acknowledge that he will give back to the girlfriend after Mepewa. The first one? Yes. Open. I know. But if you don't have any money, you can't take care of yourself. She's talking to more people. Did you hear that? Take care of yourself. I know you'll jump. See, he's like, you know how long you've been running out of money.  Don't say he's old, he's like, 50 something thousand. I think you know my style. I don't know how you're going to get your potential when you're back in Protein. Because she didn't want to be generalised and say some men. She did not want to go. And the fact that once you get money, you forget the chick who was there for you when you had nothing. You agree. You have to buy her a meal. I'm not saying that. I'm not saying that. I'm not saying that. Serena. Serena is going to be on the channel. No one in the family wants to see me on Instagram. I'm a very smart person. So, we're working. If you are poor and you have to go up and down town, you will have to pay for it. You will have to pay for your feelings.  You go to spend with someone who was not there for you when you were looking for that money. Let me tell you something. Sometimes you look sad. Don't pay for your class. You have to pay for your class. Exactly. Some people will say, but I am now. You have to pay for your duty. You have to pay for your duty. You have to pay for your class. You have to pay for your class. You can be full now. He is very accurate. Any man that thinks like that is a foolish man. That's the one you should check out. He is not only a snob, he is also a snob. I believe you are always like that. Check out that stiff move. Imagine I am going to hang out with the boys club. You will have to pay for your class. There are two sides of him he is actually two sides haha there are two sides he is also a person he is also a person which is very wrong trust you me he is trying to make you to his position You have to pay Ladies or women in a man's life is not just there to spend money. See what we spend the two pesos. One, who do they come and do you work with? We are very... That's how you find, I say, I'll give you money. I'll give you money, I'll give you money, I'll give you money. But we keep them to have food and to have fun with the workers. And to invest with your baby. How? In this world and it's less. The thing is, you'll find a man who will always know, and we had said this the other time, will always know the woman he will marry. From the word go. He will always know. That is true, that is true. So, you are not really finishing everything for that lady, of that guy. It is true. What do ladies bring to the table sometimes when a guy has money? And the question is, the answer is peace and direction. That is true. And that man is scared of serena, what, what, what, because the moment money goes to that guy, that guy, What is your point of view? What is this? Money. No, direction. You know. You know. Seriously. And when you find a lady that you can trust, with your money. Yes. See, the person that you can trust, the person that you can trust, the person that you can trust, the person that you can trust, the person that you can trust. Everything you want, baby, you get it.

Shop in the UK. And then, like, $1,000,000. And then, you go to VB. So, one time came, I went to the business man, they took risks when investing. Made a bad deal, invested all the money. It went south. Wow. And then, when I came back, I was like, we are poor. The only thing we have is this house. Then, the wife is like, don't worry. All the money you gave me, I've been investing. We all invested. We have, like, a lot of houses. We are not going broke any time soon. So, you tell me. How much? $15,000. How much? $15,000. Thank you. Oh, $15,000. You know the colors.

Do you think that's a keeper's son?  Ok, if you need more, you can ask your mom to take care of you and I'll take care of you too. You can ask your mom to take care of you. You can ask your mom to take care of you too. Ok, I'm going to play with my mom now. I think the mother was a fan of a keeper. I'm going to ask my mom to take care of you. I'm just trying to piece one and two together. You can ask your mom to take care of you. It's not also an easy thing I would say. You can ask your mom to take care of you. We are actually having a very tough generation that is coming up. It's very enough for the figures. I would really hope that if it's true, we are going to take a keeper. We are going to be in Kenya, in Bombay, in Tanzania. But come and see if a keeper is a keeper. Wrong move. But that's what I was going to ask. JC, this guy is a big point. He is a keeper junior. Do you think he is just using this story so that people can know him? Maybe he is genuinely concerned. He is even asking for an opportunity test. He wants his help financially and also to elevate his career in music. But other than that, he also wants to have an opportunity test. He is like his dad for real. I would say he has skills. He is a good guy. He is a good guy. He is a good guy. Yes, this is something else. I just hope to see Kiki as you have said. Because in Kenya, there is a lot of Tanzanian people. There is too much. There is too much. There is too much. There is too much. There is too much. There is too much. There is too much. I was saying that you are a good guy. I am just going to say that. Exactly. Exactly. That's what I was going to ask. He wants a patality test. I just hope if he is a keeper. So Joe, it's expensive nowadays It takes nothing You pay it to the hospital You pay it to the hospital So Joe, it's just that you're a good person and you're grateful to your family The fact that he's an artist it makes more sense So let's see if it's inborn Tricol down to your generations I hope so I know right, so many people have daddy issues I just think that daddy issues was just a ladies thing Even men have daddy issues I want to come to Kanye would you imagine Kanye having he literally broke down on stage crying saying that my dad was never around he had to go hustle it was always my mom and he started like matruzzy thinking about the moments he missed with his dad because he was never home like I wish you were there more and when you wish you were there more you see it's like the case of that guy but for him at least he heard his step dad because his mom was watching his step like you know my name really you get mad at him I know you can find it to some extent it shows it shows it's very serious it's very serious I want you to see it I want you to see it and let me tell you something people don't realize this they are breaking imagine a parent living in you it leaves a scar that doesn't go away because you always somehow blame yourself you are like why did she leave why did she have to go so this issue it just builds up it's very complicated dealing with issues they will never have gone through parenting is actually a challenge that we are having because part of the issues we are facing currently even with the current adult or young adult generation is actually because of issues with parenting we have I was looking at some research that was done that there was a lot of absenteeism, parentism that's why you are finding there is also okay there is two sides to it there is what it wants to achieve it's actually doing there is what it wants to achieve but you will find what it really wants to achieve is actually to bring the parent and the kid together it's just that but parenting has been an issue you end up becoming a parent in a very young age there is nothing as bad as snatching childhood from a child that's why you have to be part of your life unfortunately you realize that there is a point in your life that you realize that you are behaving and then you say it's middle life crisis yes, it's very early when you see people say it's life as in they are able to process it they say it's a very focused life then in Africa point the time he needs to go into something very serious there is a pull back there is a direction there is a way so it's a very big issue also paying affect relationships when you have to view relationships most of the people out here don't want to get married or don't want to marry either because they fear that their marriages will end up like their parents they have their commitment problem they don't want to be committed to someone one person because they are afraid of getting hurt yeah because they eventually leave alright now on that keep up please just have the test done it doesn't cost that much and if it's your son do write by him if he's not then well too bad he moves on at least you try and do the wise thing right and now we move on to another thing and a section of parents and social media users took to twitter with the hashtag cbcmustfall while complaining about the homework given to their children now we can all out of their competency and curriculum hitting children aged 10 and 11 some say they have found themselves forced to learn how to make scarecrows and fashion clocks and even wheel borrows out of a cardboard then that's not even all videos are making rounds on social media of children preaching while parents record and it is alleged to be part of the CRE assignments we have a video of that let's have a look alright so that was their assignment when they go out and then they have a crusade what? I'm not sure how many hours to end the police station it has not happened due to covid 19 there is one for police station I have to go to the chief of the police alright so that's the kid what you saying do we feel like we are missing out no we are always team cbc feeling we grew up in a results oriented system like we need to get 400 we need to get 400 if you are below there you will feel like I am not here I am here I am here you will feel automatically I am here I am here I am here exactly I feel cbc in achieve I am here I am here I am here I am here I am here I am here what you trying to say is that the parents should take him to church I am here I am here I am here I am here Some have a different system But we just saw two kids Exactly, there are two kids here Also, maybe this kid is part of comedy or something Maybe it's not even part of CBC Maybe it's comedy Because videos are just part of social media No, they are just part of social media My nephew was the one who took a picture of me He took a picture He went to the kitchen He took a picture and said what's up So he took a picture He took a picture So he took two pictures Let me tell you something Our makeup artist, Leslie She has to rush home Go and help the kids with homework Because homework There is a teacher who is complaining That CBC is not punishing the kids It's the parents And the kids are just coordinating I think homework is crazy Like, why do I have to do homework?

He will be there for the next five minutes. Sendio, send me a message on TV. Okay. I will send you a message. I will send you a message. I will send you a message. I will send one of your videos to Tilly.  Let me tell you something This is a book out of Rugo There is another one that we have to check out I don't know if my director has that Look at that, it's CBC in action I don't know if it's a company I don't know if it's a company It's a license It's a license because it's 50 I don't know I don't know I don't know We are having an agreement I don't know I don't know if it's a company I don't know if it's a company But this is so wrong We are teaching our kids to do this We are trying to make sure We don't have corrupt leaders But they teach them when they are young I don't know if it's a company But as much as it is It's an issue to bring parents together I don't know if it's a company Some kids As I was saying in the previous story But some of the kids didn't have That parenting there So I don't know if it's a company Or a company Right now your parent is becoming a colleague So as Jesse is saying There is the plus to it But the negative to it is Even the economic aspect Imagine you are going to school You are going to go to school And you will see And then you will see And it's actually true There is a lot of print How do you print at night? In Ushago I am going to Ushago Because at some point in my schooling I was at my grandma's So I am sure at that period of time There is no cyber If there is one It's like a place you have to walk You don't have to go to school So when there is a cyber I am at home Some kids are in the first year So they are at home But when you are on Twitter You look like you are in Ushago So where is the WAC system? I am at Ushago I am going to do a video About the Ushago I am going to show you I am going to go to school And I will be at the store At the V2 blue I will be at the display At the class And there will be a shopkeeper I didn't know there was a body scar. It was heavy, very heavy. That's why I went to the camp. That's why I didn't come to work. It was actually even in the 844. I was still in school and I had no idea what it was. But I was still in the Rapp and 2, I was just singing. Even teachers are supposed to go to undergo training. You see even some teachers still don't understand. So I saw in the news the other day that teachers are supposed to go on a mind-datory training. Oh, I heard. I think the only word I have with CBC is when it gets to the grade 6 children who move to high school High school students are very young juniors But it's okay But we will cross that bridge when we get there I think other people are making fun of it because they saw another post I am like really?  How do I want Kenyans? How do I want Kenyans? I don't know if it gets to that then I don't know if it gets to that How do I want Kenyans? I don't know if it gets to that then Sheep are cow He cannot do that You took covid-19? Yes Good one Anyway, let's hear our live story of the day no longer hiding there. They packed that. They disliked each other. This all started when Kibbe criticized Jalas over them tumba man whose videos went viral for selling clothes in Kisumu. In his own words, Kibbe told Jalas that it wasn't right for him to help a man who's cross dressing in the name of comedy. Jalas responded by telling him that he didn't regret helping a man who only wanted to put food on his table. But it didn't end there. They too have been clapping back at each other on their social pages. Now we have videos, so let's just have a look. Wherever you are, Jalas, imagine right now, man, when we're growing up, dem ain't gonna take care of you. You would look like the purest purest individual. If we are sponsored, sponsored in our country, by now, who's the one who's the one who would ever come when I'm going anywhere. Toys don't go. Now, out of the God's timing, which God? But we're LGBT community. Which God has allowed that to happen in our country? We cannot advertise homosexuality. I have refused. We're not going to advertise lesbianism. I have refused. All right. So, when Kibbe and Jalas, they do the two questions, I wash wash Kibbe. I was like, you know what? Jalas is like not so nice sometimes, but he wash wash. Come defend. So, who's a friend? Today we are friends, tomorrow nothing. When you do something, I don't like them. But do you think history will tell me the fact that Jalas is the one who took after Kibbe left that radio Africa Jalas. Do you think that's where it comes from? It's not that petty. We have a problem as a country. As in, this is somebody who is expressing his concern, and then somebody else picks it up, makes it a headline, then forces the other guy to comment, then picks that comment, amplifies it, makes it a war. And now it's like, seriously? Because if you know for a fact, it's been how long? As in, as much as, you know the way you guys say Kibbe is rough and stuff, I'm assuming he wouldn't be still holding on to something. He has his own stuff he's doing. But he's not in Kenya right now. So, holding on to that vibe. And it's very unfortunate that we have people who go to extents of pushing people to war. I'll say something about you and the way you'll find it on tabloids. And if you find it, you might find it in a popular your friends and you have to respond. The way you respond is amplified. So I'm kind of thinking this is the scenario we have. They usually just like blow things out of the ocean. Yes, and also we'll go on a whole big deal. Yes, and also we'll go on a wheelie. Kibbe was saying that guy was dressing gross, dressing and stuff and stuff. But he called out Jalas. Men call out each other every day. I was going to say, that was lambest. Yes, so you support him calling out Jalas for helping someone. Calling out each other is not a problem. But calling out about that guy is a problem. And that is what we would say. We should not be saying that. I have seen the story about it that guys are saying, oh Kibbe has been having beef over all through. Call him out for not being there. But we cannot deter him because we don't know whether he has a beef or not. You know beef is very personal. Let me tell you something. Even on Angkor over Web, some people feel like Kibbe feels like people don't talk about him much. So he's like just writing. That is what I wanted to say. So that Jalas responds. I know men love Kibbe for some reason. I don't know why. I don't hate him. But for a fact, if that guy hang here, let's speak facts. Nothing would have happened. That's the right Angkor to criticize that guy. That's the right Angkor. No, I was actually pulling up that issue. Help someone from the streets. He's just being a man. He can't tolerate that. Men cross dressing is a no for him. That guy was looking for his coin. Let's go there. That's the thing. We have our tea room and literal tea room. We're going to have to finish this conversation there. Right now, we sort out social media. But as we do that, I just want to send out my condolences to DJ Evolve's family and to him because he just lost his mom today. His mom literally just collapsed and died. That is yesterday. And it's so unfortunate. We are sending out our condolences to you and your family. DJ Evolve, and may you get well soon. We are wishing you all the best, honestly.

Todd, you ready? OK. All right, well, next up, we want to welcome Morgan Roman to the stage here. He wanted me to let you know that he works in AppSec and apparently has a dog. So please welcome up on the stage for Don't Run with Scissors. Thank you, Gio. Hi, as he said, I'm Morgan Roman. I work in AppSec. This is about how to prevent your developers from doing bad things by telling them to not run with scissors, basically. And yeah, that's actually the entire talk. Thank you. I'm done. Now, it's actually quite simple. But first, just quickly about me a little bit more. I work at DocuSign. Basically, we came up with this idea because we were tired of playing whack-a-mole with bugs. And thus, I included a picture of me playing whack-a-mole at RSA because that's what you do at RSA. And I also want to point out that I'm going to use a lot of examples. This entire talk will be examples. But I may use a particular framework or a particular library. Don't take it as just this is for this framework or this library or this kind of security issue. It's a strategy that that's what I really want to get across. So I'm going to tell you what the problem is. We have A to B. Developers are supposed to write something and make it happen. They're trying to get to A to B. So what they do is this. They go in a straight line. They do it the easy way. They do it whatever way it makes the most sense. They just parse some XML. They just use some regex. Whatever makes sense at the time, however they patch it together, they have sprints, they have other priorities. Does anyone think this is always the secure way? Yeah, yeah, it could always be the secure way. All right, I like your style. Trust, don't verify. This is usually the secure way. And this is the problem. And you need all these other steps like encoding, validation, access controls, all that sort of thing. So we want to make sure that the secure way is the easy way. So now I present you the solution, this. By the way, now this is my entire talk, and now you can all leave. It's cool. Now we're going to go through some examples because this is not the first time this has happened. But I want to just explain to everybody why you would want to do this. People like it better. When you're communicating to the developers you're working with, they are much happier and they're much more likely to go along. It doesn't impede their development and it helps you ship faster. And oftentimes nowadays you can't take in a very important application offline if it's compromised. But you do want to ship a hot fix as quick as possible. So that's the kind of idea behind this. And your training will be way more effective. OK, so first the existing examples. And then I'm going to show you all how you do it yourself. So this is not a new tactic, by the way. But it's never really been explained clearly as I'm about to do. So here is React. Who here knows what React is? It's the JavaScript flavor of the week slash year or something like that. Well, I actually really like it, even though I have no clue how to use it, for the following reason. If you notice, by default it relies on the developer, usually doesn't rely on the developer to encode the input. Basic HTML, most template languages don't do that for you. But React uses JSX and by default it does, which is awesome unless they use this horrible thing called Undangerously Set Inner HTML. And this had a laser pointer, but it's not really working. So Dangerously Set Inner HTML has a very scary name and basically says, hey, if you put something in here, it's going to be bad. And instead of having XSS everywhere, you can basically be pretty sure if someone's putting something in here, I want to investigate it. It could not be XSS, but it has a pretty high chance. And by default it's already encoded. So this is safe by default, usually, unless you need an exception. All right, let's talk about SQL injection. Previous speaker was like, hey, this is still a big deal, even though it's 30 years old. Well, you can reduce a huge amount of it if you use an ORM. Who here knows what an ORM is? Sweet, I'm with my people. All right, so object relational mapping. Instead of doing raw SQL, where you have this nice user-controlled statement right here, they can just add in whatever you want and make the query whatever you want. You can just use a built-in sort of query built-in and you don't have any sort of dynamic SQL. So there's no terrible string concatenation. There's no evil plus signs, right? And here's the truth. The developers weren't trying to write insecure code. They were trying to just do whatever query they needed. They just end up shooting themselves in the foot. So how do we make this easy? And how do you do it on lots of other things? Because I did two areas that are already taken care of, but if that solved everything, I wouldn't be up here. Well, I kind of have four steps. You find the bad pattern. You find a common sync, essentially. You make the safe pattern, the default one. Then you train the developers to use the safe pattern instead of using the bad pattern. And then finally, you make some very simple and very easy static analysis tools to ensure this works a lot better. All right. So who here knows what regex denial of service is? It's cool if you don't. I'm OK with that. Just wanted to see what the audience was like. So essentially, if you send in user-supplied regex or even just badly constructed regex, it will take exponential time. So the server will just spin out doing that process forever. And that's pretty nasty. I work at a place where we take a lot of user-supplied regex, and we want to eliminate this problem once and for all. So what you can do is you just say, all right, cool. Bad regex right here. And the developers always have to remember a timeout. And then it's safe.  It's probably going to be pretty common. So what you can do is just make your safe regex class. And you write this once, and then you handle it. If you're not super technical, don't worry about it. It's pretty simple. You say, I'm going to use the Billton regex library in our framework or Java or whatever. And then you're going to just say, it's going to, by default, always have this time span as a timeout. So you make it one or two seconds. Very simple. Now you have the safe one. Now all you have to do is train the developers to not use the dangerous one, which is here's how you can write your training. This is a template. This is AdLibs. I use this, and it's fantastic. If you use the bad way, the bad thing will happen. Instead, use the good way since it stops the bad thing. That's it. This is it. And then you include examples. And I want to highlight a few notes, right? Explain it very simply and clearly. You don't need to go and use security lingo. So you can just say, instead of saying, this causes Redos, this can say, this will cause the server to take too long to evaluate the regex, that sort of thing. I also really like to show the developer intends to do it before I show them how they should do it. So it's a weird little trick, but it's just something I've gotten from, I guess, experience doing this, that it just shows they're just more likely to say, oh, that's what I was trying to do. And then you show them how you would like them to do it. So here's the sample training. I'm not going to read this, but it basically used that nice template. And then I always like to include this example right here. So it's very clear. And it also looks about the same length, so it doesn't look more complicated. Complexity ends up getting in the way of execution. All right. So then training developers is the main thing. So training developers is usually I recommend when they get access to the repository. So that way you can give, they're usually the most excited then.  And then they're pretty open to that training. And then once a year you retrain for their specific department or whatever cadence you want. You want to make sure that you are not a cardboard security guard. You want to constantly remind them. So then let's talk about how you do basically code analysis on this to enforce these rules. So my favorite way of doing this is to go really, really easy. And that is you use basically regex. But essentially I like this tool called DevSkim because it's grep with a JSON config file. It's open source. It's made by Microsoft. It's pretty good, right?  And you notice it's escaped weird, but that's it. It will detect the bad class. Now if you want to get more specific, you can use a couple other tools. There's Roslin. There's GitHub Semantic. If you have access to other more paid tools, that's also fantastic if you really want to be more specific. This little snippet right here is exactly the code I use to detect bad classes. But it's for Roslin, which is .NET only. But you can use this on across every sort of framework and language. And also I'd like to recommend one talk by Clint Gibbler called Rolling Your Own for Rolling Your Own Static Analysis. He talks very much in depth on how to do this. So the next thing is I'm going to just show you one of these big DevSkim rules because they're actually way simpler than you think. And even though it's a big, scary blob of JSON, I'm going to break down the key parts of it. So first off, I just start with a very, very simple rule over here. And then that simple rule, I just try to aim for 80%. There's probably some edge cases around it, but you find most of the problems that way. And then the second part is you can have very, very clear description. And if you have documentation, that's good. You should link to it as well. And then to finally have exclusions, so you see my SafeRageX class, then you have an exclusion to say, hey, don't flag on this. This is amazing, right? They're following the rules exactly how we want. All right, so when do you use this? Well, during the pull request is fantastic. Most of the time developers are open to that during then. In fact, later there'll be a talk by my colleague Arvy about how to do this in very good depth. So I highly recommend you come to that. There's only one track, so you should. And also on your own cadence to go on further depth. But that's more for yourself, less for showing to the developers. All right, we stopped Redos. And that wasn't so hard. Pretty simple. All we did was find the bad pattern, make the safe pattern the default one, train the developers, gave you training, and then build tools to enforce those rules. That's it. Once again, that's my talk. Thank you. No, let's go through a couple more examples, and then we'll recap. But it was very, very easy. So XXC, who here knows what XXC is? Cool, good enough. I won't describe it then. No, when you're parsing XML, there can be parts in the header file called the header area called the DTD. And essentially, it can define weird variables that let you breathe from the file system, or you can use the billion laughs attack or all sorts of nasty things. But to block it, all you have to do is just say, hey, don't allow external entities. Easy enough, but developers oftentimes forget to do that. And most XML parsing, it by default allows you to do that. So this is weird, and nobody's ever going to remember to do that all the time. And by the way, I'm just picking on this particular Java parsing library just because I found it. There's nothing particular about it. Nearly all of them have this problem. So whatever one that your company is using, or the developers like to use, I highly recommend you just wrap it and then make your own my safe XML parser. OK, then you have the training, same format, if you do the bad thing, the bad thing will happen. And the same example of unsafe and safe. Same idea. We use the exact same strategy. Again, and I can just plug and play this anywhere. And you solve it across your entire code base. And even then, using the same tool, very, very quickly writing some regex to find this stuff. And you find the problem very quickly. All right, so we made it really easy to solve XSE across your entire code base. Easy stuff. Sorry, this isn't the cool stuff where you hack into something. This is how we can defend stuff while being really lazy. All right, so let's get a little bit more fun. Imagine getting an email like this. Looks totally legit. I like this link right here. Anyone shout out what this bug is? Just shout out. Yeah, open redirect. Love it. Mr. Robot likes it, too. No. So open redirects lets you do some nasty things. It can trick users into going to phishing sites. And if you don't block the protocol, you can also get cross-site scripting. The fix is usually to recommend people use a whitelist. So I have a whitelist right here. And now let's play a game called Let's Spot the Bug. If you can't see it from that far, I apologize. But just yell out if you're able to see what one of the bugs are. Isn't anchored, what do you mean? Bingo. So that's one of the big ones. You can basically say it's part of the query string or part of the put at the end, or you could do subdomain silliness. So yeah, that's the nasty part. As he said, you can put this part of the regex anywhere you want in the string to show some examples of what could go wrong. The first one is saying, hey, I could just make this part of the subdomain. And then myevilwebsite.com, you can redirect to there. Then you could do evilwebsite.com, and then you could just put it at the end in the query string parameter. Or, hey, there's nothing blocked in the protocol, so my safewebsite.com, and voila, a little bit of XSS for you. It just needs to contain the string. So what I recommend is you create a safe redirect method or library that just works with your existing code base. And what I'd usually do is you an internal redirect that blocks bad protocols and also only redirects to your own site. And the nice thing about it is if the developers use this, you can usually assume it's safe, which is quite nice. So you take about 50% of the problem away instantly. And then the ones where they do use external redirects, you can just audit these and just ensure that they're doing it properly. And that's pretty quick to pick up with some static analysis, repping with a JSON file. All right. One more example. This one is server-side request forgery. Anyone know server-side request forgery? Just raise your hand if you know. Sweet, all right, I got my tribe. So essentially, you're able to get one server that you don't own to make a H2B call or any other web call whatever to another server. In this case, maybe you might not be able to attack this server directly because there's a firewall blocking it. But if you can talk to this server and then make a server-side request forgery, let's pretend they're all microservices. And one's hidden behind the firewall. Then you can talk to it as you want, right? There's lots of other nasty things you can do with that. Like, let's pretend you had server-side request forgery in C sharp, just as an example. Well, you can get past the firewall. Here's some other nasty things. You can call servers with long responses. So that's a good nice little denial-service tactic right there. My favorite thing, though, is by default in .NET and you have to check with whatever framework you're using, if it's Java, Ruby, et cetera, is by default, file reads and file writes and web request calls are essentially the same thing unless you cast them. So you can do a file read to some secret file. Or you can write and just take down the website or get remote code execution, which is fun stuff. So how do you defend about this? Well, you make a safe version of it, right? Sometimes you have to do this. And then sometimes you get this scary acronym if you have a webhook, right? And I'm not going to even say that, it's that offensive. But essentially, you have to allow your server to make external calls. And sometimes users are defined, right? But you can block internal IPs areas they shouldn't be talking to. You can have built-in timeouts. And you can block calls to the file system, because that's super nasty. And the safe version that inherits all the features of your web client library. So you don't have to rewrite everything, you're just setting the right settings on your safe class. All right, recap. Because I went very fast, but the strategy is the key thing about this, not the particular examples. You find the bad pattern. My rule is for this, it doesn't work for all bugs. But if you can find a common sync, for example, all regex denial service requires regex, right? All xxc requires xml. All server-side requests forgery requires a web request. So they have a common sync. Therefore, if you find a common sync, it's usually a pretty good pattern to try. The next thing is you make the safe pattern the default one. You make it very easy for the developer. And it's something like my safe regex, or safe whatever. And then you do it once right, and you maintain that. It's something that if you have an app stack department, or whoever you decide to do it, just has to maintain and make sure it's OK. But it's usually fairly simple and fairly easy to do. And then you train developers to use the safe pattern. Take a picture of the slide, because it's fantastic, because you don't have to rethink on how you're going to write it every single time. I use this all the time. Cool. I see you there. Cool. It's OK. These will be online later. And then once again, put in an example, because that really helps get the point across. And then you build tools. Now I highly recommend DevSkim, because it's really easy. And you can get something up and running really quick. But if you have a more complicated tool that you prefer, go for it. It's your choice. But having this to enforce the rules is highly valuable. And I highly recommend you do it just like 80% effective. Don't worry about getting all of the security bugs. It's OK. That's a weird thing to say at a security conference. It's like, get started. Don't worry about it. And once again, very, very simple rules. So once again, I'm going to recap one last time. So if I didn't hammer in enough, basically you find the bad pattern. You make the safe pattern, the default one. You write good documentation around to use it and good training. And then you build tools and enforce these new rules. And then you've just annihilated entire security problems in your code base. And then you got to do this. And it's easy. A to B. I like it. If you want to contact me, here's my contact information. And I'll be taking questions after this talk. Let's have lunch.


If I could say anything, man, it would be that the system that you have right now where you do a quarterly email and then you kind of go through your phone and text a couple people or whatever here and there, that's not a scalable activity, right? So I'm, uh, I'm based out of the Michigan market, uh, Metro Detroit area. So I service three different, um, three different counties, Wayne Oakland and McComb. Um, we're starting to see, you know, a little bit of a rise in supply. I just wanted to see if that's kind of the same thing in your market, Florida, and what you're doing, um, to kind of hit this shift that we're heading into. Everybody's talking about it.  Now we're against seeing that shift. Is that kind of the same thing you guys are seeing? Yeah. Man, listen, it's, it's, it's been totally, this was completely predicted, right? Like this, like there's no way that you can be in this market and have any kind of experience and not have seen this coming, right? Right. Um, I mean, I've been talking about this from the moment. Anytime a market is like super busy. Um, that's a dead giveaway that it's about to slow down at some point. And every time it slows down, that's a dead giveaway that it's about to speed up. That's why when the, when the, uh, shutdown happened last year, I knew that the market was about to explode because things almost came to a halt there. You know, um, which really wasn't a halt. It felt like a halt, but really 80% of the same amount of business was happening. Um, you know, so no, man, listen, that the story is the same in every single, like, um, you know, cycle of the market.  Right. That we stay in front of people because when the market shifts, like the market shifting is going to create a lot of opportunity because, uh, you know, there's all kinds of sellers that are saying, Oh, I'd love to sell at these high prices, but there's nowhere to move to. So what is more inventory going to do? It's going to create a situation where these sellers have a place to go to and they may be more apt to upgrade from where they are, sell what they got and upgrade to their dream home. Um, there's a lot of that's going to happen. As we see, uh, inventory continue to increase the people that are sitting around saying, Oh, it's, it's the market's changing.  Right. I mean, every time the market changes creates another avenue of opportunity. You know what I mean? It opens up so much. So for people, people that were just in this past market over the past, you know, eight or nine months where, you know, every buyer was competing against, you know, 15 other buyers and you had to pay 50 to 100,000 more than what they're asking. You know, those agents are like, I can't win for losing. I've been put in like 12 offers and I can't get anything. You know, and now inventory is coming up or buyers actually have options.  You know, it's like you've got two kinds of agents.  And the market could turn around on a dime and be completely opposite of what it was, and they'll still say it sucks. And then you've got the agents who sit around and, and see an opportunity in every single type of market. Right. And there's massive opportunity in every single market. Right. And it's all just perspective. So the story is all the same man.   You send a weekly email and you ball. Yeah. Amen. So that was the one thing I struggled with. And I actually, I have your zero to diamond emails coming in. And, uh, I don't do a weekly email. I do a quarterly email. Um, I typically, I like to reach out to people by text. So instead of, um, sending out like a weekly email, that's a little bit more generic. I like to take like a certain number of letters and last name of my, in my database and just kind of send them like a love tab with the text. And that seems to be like it's, uh, it works a little better. Just like, Hey, how are you doing? You know, is, is there anything I can do to help? Um, are you set, you know, satisfied if it's a previous client? You know, are you satisfied with what, what's, uh, what's happened so far, whether they were a seller buyer previously with me and then, uh, just kind of see where that can warm up to and what, you know, low hanging fruits I can, I can pick from, um, as opposed to, uh, you know, just kind of constantly going through, but still I, I'm doing my day to day calls. I'll do 25 fizz bows and like 20 or 25 expires. Um, so it's not like a crazy amount of calls, but it's enough to get my day started and it feels good. Like, you know, in this business, um, you're going to get rejection. You're going to get nose, but those nose can turn to yeses. Like you've proven time and time again. I've seen a lot of your content, you know, just following up and, and doing relationships over transactions really helps and, and that's helping boost my business. So I wanted to, I definitely wanted to get on here and thank you for that. So, um, you know, the content that you deliver really, uh, allowed me to push myself a little bit more. Well, if I could say anything, man, it would be that the system that you have right now where you do a quarterly email and then you kind of go through your phone and text a couple of people or whatever here and there, that's not a scalable activity. Right. Mm hmm. Like if you had 5,000 people, right? If you had 5,000 people, you couldn't do that. Now you can bulk tax, you know, you can do the bulk tax where you have like a smart number and, you know, you can create like a bulk tax where you do hit all 5,000 people via text messages and that's fine and everything, but I mean, like your quarterly email, I'm guessing because you use the word generic. It's probably like a generic newsletter. Yeah, it's pretty generic. Yeah, yeah, yeah. So what, so listen, man, if you really want to ramp your business up and get to the point where I am, where I don't make any calls anymore and I close 100 deals a year and all I do is a weekly email, you need to start doing a weekly email and you need to sit down every week for 30 minutes and actually put it together where you actually write it and it's really good stuff that comes out of your mind and gives them a little bit of your personality. Right. Not a generic. It's not generic, right? I write the email every week and I tell people what I think and give them my opinions on stuff. And I mean, I'm closing 100. Does that change with the different markets? Like if you work one county and you work another county, will it differ a little bit in those emails? No, listen, you put everybody in the same email and then within the email you have click on your county and you can have like a box that's there every email where they click on their county, which goes to a dedicated page in your website that gives them all the information on that county that you want to share with them. That way you can send the same email to everybody. But if they want to go get more information on their county with what's sold or this or that, they can click, they can click one click and go to your website, which has a page dedicated to that county. You know what I mean?  I mean, that's not doing anything.  So you need to see weekly. It needs to be personal. What needs to be weekly? Weekly is the perfect frequency. Whereas they feel like this person is consistent. They're hardworking. They're dependable. And they start to think all these incredible things about you. You know, as they're getting this email and listen, man, the people that unsubscribe from a weekly email, they're going to unsubscribe from a monthly email, a quarterly email, a yearly email. Those people don't even get emails. So don't even worry about people unsubscribing.  And people are going to love you. OK. And then you can scale that to the moon. Yeah, no kidding. I guess that's one thing I've kind of been missing from my businesses. Like, OK, you know, I found the spot.  I mean, you know, I was talking to a lot of investors, door knocking, doing open houses, things like that. And eventually I found some success in it. And those that success generated referrals. And I kind of hit like a plateau. But it's nice to hear you say that because that allows me to expand my business a little bit more by scaling up, like you said, actually feeding into that, you know, personability and branding and getting out there. And that makes sense. A hundred percent. Just spend time on it, right? Just spend time on it every week. Make it your baby, right? And realize that it's going to be the foundation of you of you getting to a place where you can close 50 to 100 deals every year just to pass kinds and referrals. Absolutely. Right. OK. Cool. Cool, man. Everything going good in Florida? You guys staying busy now? Yeah, we're good, man. Just staying busy down here. Cool. Yeah. Where typically would you say the most transactions happen? Like what county is that you work in? Are you seeing the most traction out of? County wise? Yeah. I mean, I'm just down here. I'm actually in Baldwin County, Alabama, right on the right on the Florida line. And, you know, I sell mostly golf front condos and beachfront houses and stuff like that. But, you know, it's, listen, it's busy everywhere, man. That's what you have to realize is that no doubt. And do like it's unlimited. You can't do all the deals, man. It's like it's like trying to drink the ocean. You know what I mean? Right. That's what that's what trying to do all the deals is like. It'll never happen.  Absolutely. I appreciate the words. Yeah, man. All right. Thanks so much for going there. You're busy, man. So I'm going to keep you too long. But thanks so much. I appreciate your time. And hopefully we'll be in touch soon. Yeah, bro. Good conversation, man. I'll hit you up later. Awesome.


Hi, I'm Zor. Welcome to Unisor Education. We will solve a couple of very simple problems related to mechanical oscillations with damping effect of the friction. Now, this lecture is part of the course called Physics for Teens, presented on Unisor.com. So this is the website where I recommend you to watch this and all other lectures because it presents a course which means it's a logical connection between different lectures. There is a menu which drives you in a logical sequence from one lecture to another, from one topic to another. Every lecture on this website has a very detailed notes which basically can serve as a textbook. The site is completely free. There are no advertisements, no strings attached at all. You don't even have to sign in if you don't want to. Also the same website contains Mass for Teens course which basically is a prerequisite for physics. You do have to know mass. I'm using, especially the calculus, I'm using differentials and integrals practically in most of the lectures. Physics is all about calculus, quite frankly. Okay, so damping effect of the friction. Okay, consider the hand falling problem. So you have a table. You have a spring attached to the wall and attached to the object. Now, let's characterize the object with mass which is equal to 0.3 kilograms. I'm using the C units of measurements. Now, the spring has elasticity equal to 2 Newton by a meter, which means if you stretch it by a meter you will get 2 Newton's force back to... So any extension by certain amount of certain distance will cause the spring force multiplied by 2. The distance multiplied by 2. So if you stretch 1 meter it will be 2 Newton's. If you stretch half a meter it will be 1 Newton. If you stretch 2 meters it will be 4 Newton's. So that's what elasticity coefficient is. And we also need friction which is 0.1. So this is a ratio between... Okay, if you have certain force of the weight you have to multiply by this friction coefficient to get the force of the friction which prevents the movement of the body. Sometimes we differentiate between static friction when the object actually is sitting and it needs an initial effort to move it. From dynamic friction whenever it's already moving the resistance to the movement. And usually static is greater than dynamic. It's more difficult to start movement from some kind of a standing position than to continue movement. But let's just for simplicity consider that these static and dynamic are the same. Okay, so what's my problem? My problem is whenever I'm stretching the spring to a certain distance I will have the force of the spring which will pull it back to initial equilibrium position. Initially let's assume it's equilibrium so the spring is not stretched, not squeezed. But now at the same time when I stretch it to a certain position not only the spring will attempt to pull it back also the friction will prevent it to move, right? So if I...now this force of friction is always the same. It's weight times coefficient.  So m times g is the weight and times mu gives me the force. The force is always constant and it always prevents the movement. Now the spring whenever I'm stretching it to certain distance if you multiply this distance by the coefficient of efficiency will give it also the force. So my problem is what's the maximum distance I should move this particular body so the spring will have enough force to initiate the movement. Because if I will just move it just very very little my force of the friction will be exactly the same. My spring pulling force pulling back to the equilibrium will be very small because this distance I'm stretching very small. But the greater I stretch the greater the force of the spring. So I can actually manipulate with a position. So the spring will have different force, the force will be stronger the further I will move it from the equilibrium. But the friction is exactly the same. Looking for a specific position, maximum position I can stretch without spring being able to move it back. So again if I'm stretching too little spring will not be strong enough to pull back because the force of the friction will prevent it. So when exactly will be that maximum distance I can move where my spring will not be able to pull it back. Well obviously my force of the spring depending on x if x is a distance I'm stretching then the force of the spring which obviously depends on the x would be equal to k times x. That's the meaning of the Hooke's law. The distance I'm stretching times coefficient of elasticity that's the force. Now this force will be very small when x is small but the bigger is x the bigger is force. So I'm looking for the maximum when the force will be equal to the force of the friction. So basically I have to resolve this equation from which x is equal to mu mg divided by k which is equal to 0.3 times mu is 0.1 times mass is 0.3 times g is 9.8 divided by 2 which is equal to 270 to 94 to 94000 so it's 0.294 divided by 2 which is equal to 0.147 which is we're talking about meters right equals 147 millimeters. So under these conditions I have to move my object no more than 147 millimeters in order to spring not being able to move the body back. If I will stretch it more than 147 millimeters then the spring will have sufficient force to move it back. How much back? It's a different question but that would be actually a second problem. Okay that's the answer to the first problem. Now the second problem it has the same setup. Okay now I'm looking for another distance I have to stretch. Now if I will move it further than 147 let me just write 147 millimeters it's by the way it's called critical distance and there is a special letter lambda which I'm using so that's the critical distance. Before that critical distance my movement will not initiate the pulling back starting from just a little greater than 147 my spring will be sufficiently strong to start movement. How much farther? Well not much because as soon as my spring it will start moving back to the original it will cross 147 millimeters boundary but then after that the strength of the spring will not be sufficient because we are shortening spring so the pulling back strength will not be sufficient to move it much farther so it will move just a little bit beyond this point and stop. So my point is how far I have to really move it outside so the spring will initiate movement but then it will be strong enough all the way until the body will reach the equilibrium point and stop. That's what's interesting it's stop. What it means? It means that the energy which has been accumulated by moving my object to the right potential energy of the spring will be spent completely on the way from that position back to the equilibrium and then this object will stop which means there is no kinetic energy and no potential energy. No potential energy because it's equilibrium point and the spring has no potential energy in equilibrium point and kinetic energy will be zero because I'm saying that the condition of this particular problem is the body should stop, the object should stop at that point. So it's all about energy. Again, as soon as we stretch the spring it accumulates the potential energy. As soon as we let it go potential energy will start converting into kinetic energy of the movement so potential energy is diminishing because the spring will be shorter and shorter from the squeezed position but kinetic energy will still be something whatever the kinetic energy is but energy will be spent to friction because friction will have to do some work. This is a constant force of friction so on the way from that stretched position to the neutral position will always be working against the movement so energy will be spent. So the idea is to find out what's the potential energy whenever I'm stretching to a certain distance and then that same distance should be used to calculate the work which friction force will perform and just equate them and that would be my equation. Okay, so how can I calculate the potential energy of the spring when it's being stretched? Well, I did address it in the lecture but let me just talk about this again. Let's consider this is your spring and you have stretched this particular body to a distance x and then x plus dx. So dx is infinitesimal infinitesimal increment of the distance. Now whenever my object is at position x the force of the spring which depends obviously on this position is equal to coefficient of elasticity comes the distance increment so this is zero and this is x. So my force obviously depends on the distance x. Now as always in physics and mathematics we are assuming that on this infinitesimal increment of the distance my force is the same and so my work which this force should actually perform on this distance should be differential of w of x is equal to f spring of x times dx. So the force times the distance, that's the work. So the force I assume is the same on this particular infinitesimal distance which is equal to this and then force I multiply by the distance to give my work and this is only differential of the work an infinitesimal increment of the work which spring is doing whenever I'm moving an object from x to x plus dx. How should they do how should they calculate my work if I would like to stretch it on the distance a? Well I have to integrate it from zero to a which is basically a summation of this infinitesimal number of infinitesimally small pieces of distance and infinitesimally small increments of the work. So what is this? This is integral from zero to a f is this, this is a very simple integral. Now this is a definite integral to get it using the Newton's wave needs formula I have to have an indefinite integral which is kx squared divided by 2 because the derivative of this is kx k is a multiplied derivative of x squared is 2x divided by 2 would be x so this should be substituted from zero to a so I substitute the first one a minus the second one but the second one is zero so it would just total work which depends on a would be equal to k a squared divided by 2 and that's all I need right now from the spring. Now this is the work which spring is doing well against the force of spring by stretching the spring so we have stretched the spring by distance a and that's the potential energy which we are giving to this particular object because we are spending our energy to overcome the resistance of the spring so we are basically transferring our energy working by stretching the spring and we are actually giving it to the body this object now stretched by the distance a has this amount of potential energy okay now whenever I let it go and the spring will start pulling back my condition is that this same energy should be completely spent on the way back to the position of zero to equilibrium position now this energy is spent to a friction friction has always the same constant this is the constant force so to find out the work which friction is doing I have to just multiply this constant force by the distance well distance is a so my work which friction course performs is mu Mg times distance which is a so this is the work which friction performs on the way back to equilibrium and it should be exactly equal so the kinetic energy would be zero at the end of the point no speed and the potential energy is zero because it's equilibrium point so it should be equal to the potential energy accumulated by the object when I stretch the spring and that's the equation and A is an unknown variable so we'll just solve this equation which is very simple A can be cancelled out so A is equal to 2 mu Mg divided by k which is equal to well I didn't write it down but this lambda was equal to mu Mg divided by k so it's twice as much very interesting, right? so the critical distance is this which is 147 and the distance which is supposed to be such that the object will move back exactly to the equilibrium point where it started is twice as much so let me just calculate it so it's 2 times mu which is 0.1 times mass times acceleration divided by 2 which is equal to so it's 3 times 0.294 meters 294 millimeters which is twice as much as this one so what's interesting is whenever I am stretching beyond the critical point and I did actually talk about this in the lecture my spring will start pulling back and it will stop on a point which is symmetrical to critical point so this is lambda, critical point so this is the beginning this is 0 and this is A so if I am stretching it twice the critical distance it will go back symmetrically relative to this if I stretch it greater it will go beyond the zero point so it will start oscillating now if it's within from lambda to twice lambda it will just go back maximum to a zero if I stretch it less than to lambda it will stop symmetrically if I stretch it greater than to lambda it will go here and then it will start oscillating because on this side it will be repeating the same thing relative to the critical position on this side well, basically that's it these are two problems I do suggest you to read the same two problems on the website and Unisor.com you have to go to physics for teens course this is the part which is called waves and the topic is mechanical waves now in the mechanical waves topic you have lots of lectures and this is the problem number two within the mechanical oscillation topic that's it, thank you very much and good luck


the dark tower journey is not. I am a big fan of traffic lights. Hey guys, it's Liana and I'm here today with my mid-year check-in. So at the end of 2020, I posted two videos with goals for the year. One was series that I wanted to start, and one was series that I wanted to finish in 2021. So I thought, now we're about the halfway point of 2021, let's see where I'm at with those goals. So let's start with series that I planned to start. I had 11 series in that video that I listed as series that I wanted to start. So for both of these categories, series to start and series to finish, I have sort of labeled them, you can't see this, but I've labeled them in my list, red, yellow, green, because I am a big fan of traffic lights. Because I labeled the ones that I have achieved in green, the ones that I'm either I have made some progress on or I'm about to start or like I'm in the yellow zone on, yellow, and then the ones that I have not touched in any way, shape, or form, not even thought about are in red. For series to start, we're going to go with green first, then yellow, and then red. Of the 11 on my list, I got four in green, three in yellow, and four in red. So so pretty good. Pretty solid for halfway through the year. First up, Malazan Book of the Fallen. I did start that series, I will not be continuing that series. And that's all I'm going to say about that. Next, I had Book of the New Stone by Gene Wolfe. I sneakily picked that as the book club book when it was my turn for Blades and Bytes Rippers. So that is a goal achieved. If you want to see our live show on that, that was on my channel because it was my pick. And unfortunately, I did end up liking it and I plan to continue my series. All of my co-hosts did not feel that way about it. So there is a variety of opinion on offer in that live show. Third, I had Fireborn, which I think the series is actually called like the Aurelian Cycle. Probably should have checked that before turning my camera on. Yeah, it is the Aurelian Cycle by Rosaria Mundy, if I didn't say. And I ended up quite enjoying that as well. I think it was slightly overhyped for me. But overall, I do think it was quite excellent. Not loving the cover change, which is a shame because I do like the series, so I would like to continue on and I would like to get the next book, but the next book doesn't match the first book. And this greatly displeases me, but I will at some point read Flamefall when I get over my loathing of the cover. Next, I had Black Company by Glenn Cook, which I also sneakily chose for Book Club. I'm not doing that again this year. My third and final pick for Book Club this year is not any of my goals. Not that there's anything wrong with choosing a goals book as my Book Club book. In any event, the live show for that is also on my channel. It was in January, I want to say. And none of us liked it, and I will not be continuing on with that series. I found it interesting as a progenitor of Grimdark to see where this all began, one of my all-time favorite genres or subgenres.  So, on to my yellow tier, where I have dipped a toe or I'm about to dip a toe into this goal. I had Dark Tower, which I am pleased to announce I will be starting next month. Bethany actually will be reading with me at least the first book, The Gunslinger. And then depending on how we do with that, we may continue on and buddy read the rest of the Dark Tower books. But she and I will both be embarking on our Dark Tower journey in July. So that's why I have it in yellow, because the Dark Tower journey is not. The same thing with Liveship Traders. I had to obviously finish the Farsier trilogy in order to start the Liveship Traders series and Mara and I intend to pick up Liveship Traders or the first book, Mad Ship. No, I keep saying Mad Ship. Ship of Magic in July. So that is also in yellow because it is nigh. Likewise, the Book of Babel, which the first book is Sunlinna Stentons, I was planning to pick up this year. Obviously it's on my list of goals from that video. And I have reason to believe that I will be made to read this in July. So stay tuned for that. In the red category, i.e. I have not even thought about this, our Wheel of Time, which I am now dreading more and more because I've read some things that people have compared to Wheel of Time and I have greatly disliked them. I am curious to see the adaptation of the show that I think is at Amazon doing it. So me being me, I would like to have Red Wheel, uh, buy of the world at the very least before that comes out so that I can say, well, in the book. So if nothing else, that's a good impetus for me to actually pick it up. But I am kind of dreading it. And then I have Dresden Files, which I anticipate disliking to start out. I've heard almost every single person say that they don't like the beginning, that the first is the weakest, and that even the people that like the whole series, even the people that like the first book will say it is the weakest and that they don't blame people who dislike the first book. I still want to start it. I am fully prepared for disliking the first one, depending on how strong that dislike is. Like, I guess I'm hoping to find out when I pick it up if I see enough like seeds for something that could be good with a lot of work. Because I suspect if like the entire project of it just puts me off, like I don't think I'll ever like it. But if it's something where I'm like, oh, like this is rough, and I don't, you know, this is kind of sexist, and this is kind of weak, and this is kind of dumb. But like, I see how this could be good. If I feel that way about it, then I will be willing to go on. But we shall see. Maybe I'll be one of those people that loves it from the get go. I think that's unlikely. But maybe I will be. Who knows? Who knows? No one ever knows my taste. I don't know with my own taste. And I also had Lock and Key, which I low key forgot that I even had on this list when I was looking at the list, because I kind of abbreviate books when I put them in the description. And I just saw Lock in the description, and I was like, the lives of Lock LaMora, but I have read all the books that are out in that series. What was I smoking? And then I clicked on it, and I was like, I don't know, Lock and Key, forgot that that existed. It's a series of graphic novels by Is it by Joe Hill? I think it's by Joe Hill. I watched the adaptation on Netflix, and I really, really enjoyed that. And the audio on the audible dramatization is included in Audible Plus. So I planned to do with Lock and Key the same thing that I did with Sandman, where I would flip through the graphic novel and listen along, except this was a little bit of a problem with Sandman, where it kind of, like it was slightly different in the, it wasn't entirely the same order. It was mostly the same order, but there were a couple of times where I was like, wait, what page are you on? This is not describing what I'm seeing. Lock and Key was way worse, because I did originally start it like a very little bit last October, and I quickly stopped because I was realizing that this is just all over the place and so out of order. So I was like, oh, figure you out later. And then I had, I forgot about it entirely. So whoopsie. Maybe this October I'll actually do it. And last I had Dark Artifices by Cassandra Clare. I did actually make progress on that. I read like two pages. I didn't put it in yellow because I don't think that's really progress. One afternoon I was like, you know what? I'm in the mood for some YA cliché, tropey, angsty fantasy. And then that mood ended after two pages. And it wasn't like the book put me off. I don't want to make it sound like that. I just, it was this like brief whim where I was like, that's what I'm vibing. That craving went away almost instantly. And again, it wasn't because of the book. It just, it was this momentary whim. And then I was like, what? No, I have too many books on my TBR. What? I don't know. I'll read this right now. So it was quickly abandoned. But I do want to read it. And I do think that when the mood is right, I think there's a very high possibility that I will enjoy it. And I would like to enjoy it, ideally. I always want to enjoy what I read. The shocking is that it's to hear for some people. So yeah, that does it for series to start. I have, of the 11 that I wanted to start, I have started for. I'm about to start three more. So that's seven out of 11. And then, and we'll see how we go with the last four that have not been touched. As for series to finish, I had 13. Much more ambitious. And this list of 13 wasn't even a list of every series that I'm in the middle of. It was just the series that I was like, oh, that's prioritize things. Some of them because the final installment would be coming out this year. Now, one of the ones that I marked in green, I'm sticking with that green. But I think I guess technically it's not true, but we'll get to that one. Any hoosies. First, I have winter night trilogy. I just finished that trilogy last month, the winter of the witch. And I really, really enjoyed it. I think the second book in that trilogy is my favorite. But overall, really, really enjoyed that trilogy. I kind of wish that I had finished it in winter, even though I live in Los Angeles, where winter, who is she? But just, you know, winter mental vibes, even though it is always hot and sunny and filled with palm trees, regardless of the season. Next, I have Broken Earth by N. K. Jemisin. I actually have a video of reviewing, discussing whatever the Broken Earth trilogy on my channel. Love, love, love, love, love it. That was the most attainable goal because I had actually even started reading the third book in 2020, so I just had to finish that book. And I did, and was God of Snack and Blown Away, continue to be God of Snack and Blown Away at N. K. Jemisin is just, is she even human? Love, love, love it so much. And I have actually, even though it wasn't on my list of series to start, I embarked on another N. K. Jemisin journey earlier this year. Started the inheritance trilogy. I don't know if I'll be finishing that series this year, since I haven't even finished the series that I planned to finish. Truly Devious is the one that I was like, is this true? Because as far as I knew when I put this on my list, this is a trilogy. And I finished that trilogy, but now there is a new book coming out. As of the filming of this video, it's not out yet, but I think it's coming out next week. And I think that book is a spit off. So I don't know if I can say I finished the Truly Devious series because that book is a Truly Devious novel, but it's not part of the, like the arc was concluded, the mystery was solved, story over. So I finished The Hand on the Wall, and I liked it. And I would like to read more. It's not like I'm put off. I'm more Truly Devious books. Sure, bring it on. I enjoyed it.  Now for the yellow tier, these are series that I have made progress on, but I have not finished. So I've got two of those. First I have Scythe, the Ark of the Scythe by Neil Schusterman. I was worried that I would have to reread Scythe in order to be able to move on at all in the series, but I picked up Thunderhead and found that I did not need to reread Scythe. It was, it came back to me as I went. Now I'm really stoked to read the Toll because Thunderhead was even better than Scythe and I am so excited to see where this all goes and wraps up. The Toll is even longer. Each book gets progressively longer. So, yikes, but I'll find the time. I'm really excited about that. And then the other yellow is Lord of the Rings. I read Two Towers a couple of months ago, so I just have Return of the King to go. I can do it. I can do it. It will happen, but it has not happened yet. But when we, when we check in at the end of the year on my goals, which maybe me, maybe I'll do, probably I'll do, I feel confident in saying that I'll be able to report that I finished Lord of the Rings. But then I've got one, two, three, four, five, six, seven that I have not touched that are in red. First I have Rearrier Revelations by Michael J. Sullivan. I have Theft of Swords to go, which I think is reasonable. Not Theft of Swords. When am I even saying Air of Navron? Theft of Swords is the first one. What is wrong with me? Now, this is weird because this trilogy actually gets progressively shorter. Theft of Swords is the longest and then Rise of Empire is a little shorter. And Air of Navron is either the same length as Rise of Empire. Maybe it's slightly longer, but it's not as long as Theft of Swords. And each of the books in that trilogy is actually a bind up of two. So it's six books. But yeah, I would like to finish the Rearrier Revelations so that I can finally read the Rearrier Chronicles so that I can finally read the, what is it, Age of... Legends of the First Empire? Yes, Legends of the First Empire, which begins at Age of Myth. Jashon is a big fan of those books. And I picked up Age of Myth when it first came out, not knowing it was anything to do with anything else, and then found that out and then bought all of the books that came before. Now I just have a buttload of Michael J. Sullivan books.  Next I have Poppy War. I was also worried that I would need to reread Poppy War if I'm going to read Dragon Republic and The Burning God? The Burning God. However, I think it was Patrick that sent me a link to a catch-up summary for what happens in Poppy War, which I will definitely be taking advantage of because last year when I attempted to pick up Dragon Republic, I was like, oh god, I don't think I remember enough. So that will happen, but I definitely need to check out that summary before I pick up Dragon Republic. I just, I know Dragon Republic is going to be dark.  And I'm just, I can do it. I can do it. I just haven't been wanting to put myself through that. But I do want to read it because I hear it's excellent and I did really enjoy Poppy War. But I just, I haven't felt ready to put myself through that. Next Shatter Me, which I've put off for a long time, not that long, but quite a while because I just kept hearing from everybody, people who were big fans of the sequel books and people who were not fans of the sequel books alike agreeing that Imagine Me, the last book is shit, which doesn't bode well. If it was just the people that were hating the new books, I'd be like, well, screw you because Restore Me was probably my favorite in the series. But Defy Me was already a step down. And then again, literally everyone has said that Imagine Me is... I want to finish it, knock it off my to-do list, but I'm not looking forward to it. Next I have The Chronicles of Predane by Lloyd Alexander. They're all really short books. I've read the first two. I think there's, there's five or six. Definitely at least five, but possibly six. They're behind me, aren't they? There's five. So I have three to go. And they're really, again, they're really short. I think the last two naturally are longer because every series tends to get longer as it goes, doesn't it? But they're quick reads, they're fun reads, they're kind of winter reads. So I'll probably be leaning towards picking those up in fall, which again, like fall to me is when stores decide to use fall aesthetic in their window dressing. But nevertheless, what I'm in a fall mindset is when I'll be picking those up likely. Next I had The Age of Madness by Robert Cromby. This I cannot have made progress on because the third and final book, which I have been eagerly anticipating does not come out until September. I have been very steadfastly reading a book a month from the first law books leading up to the release of the new one. So I am very ready for the new book to come out. But until then, I still have sharp ends, then my reread of A Little Hatred and my reread of The Trouble with These, and then with Tim of Crowds. We cannot wait. And I have The Ember in the Ashes or Enema in the Ashes by Sabah Tahir. Once again, I have heard fairly negative things about how this quartet wraps up, which is disappointing to me. I love the first two books so much. I thought the third book was a bit long, and I was starting to feel like the series was kind of like getting long and needed to wrap up. But I was hopeful that Reaper of the Gates was kind of, I know that a lot, I don't usually tend to feel this way about middle books, but people complained about middle book syndrome in trilogies. Middle books tend to be my favorites, but I was feeling like maybe this is kind of a middle book syndrome type thing, where this is a book that's bridging us into the next, into the conclusion. So maybe it feels a bit that way, but I'm fine with it if it means that like this next book is going to be what all this has been building towards, but I've been seeing quite negative reception for Sky Beyond the Storm. I want to finish it because I want to finish it, but I am at Winsu. And the same is pretty much true for the last one of the list, which is The Imperium Trilogy by Clara LeGrand. I love Furyborn so much, I read it twice. But then I heard from a lot of people who were likewise fans of Furyborn that they really did not like Kingsmane, which was the second one. And so I never even started reading it. And now the trilogy is concluded. And I want to read it. And I want to know what I think of it because I loved Furyborn. And actually Rachel from Reasons Rachel loves the whole trilogy. And her tastes in mind sometimes align and sometimes don't. She and I both obviously love Furyborn, but then she went on to read the rest of the series. And she's about the only person that I know that I know somewhat well or intimately who actually liked Kingsmane. I sent her the arc copy that I had of it. What is the light bringer? Is that the last book? I don't know. Anyway, she likes the whole trilogy. So I'm hopeful. It's not that everyone is hated. Unlike with Shadow Meatware, literally everybody thinks Imagine Me is garbage.  But with Imperium, it's been a lot of negativity, but this this glimmer of positivity from Rachel. So I would like to read these books. But I'm a little afraid they're going to ruin Furyborn, which I love very much. But we'll do it. We'll do it at some point. So let me know in the comments down below your thoughts and feelings about these various series that I am at various states of completion with. If there's any that you think that I really should make an effort to prioritize. I mean, in theory, all of these are my priority because they were all on my list of series that I would be prioritizing.   Don't worry too much about it. Let me know that as well. I post videos on Saturdays, other random times as well, but definitely Saturdays. So like and subscribe, join my Patreon if you feel so inclined, and I'll see you when I see you. Bye.
