The study found that perioperative enacetylcysteine, NAC, administration did not significantly reduce the risk of cardiac surgery associated acute kidney injury, CSA-AKI, in adults undergoing elective cardiac surgery, as evidenced by similar rates of CSA-AKI occurrence, change in creatinine levels, and in-hospital mortality between NAC-treated and placebo groups.

The Bedford Group is an amazing organisation that changes the lives of people with a disability every day through employment, training and life skills development. Workplace health and safety is critical for Bedford, it is the essence of everything that we do and by having a safe workplace we get the best out of our people. It also allows people regardless of what their limitations are to participate actively in work. We have a diverse range of hazards that we have to manage and the key way that we manage safety is to get our people to be safety aware and be empowered to make decisions around their own safety to look after themselves and to look after their mates. Make sure that they feel comfortable to call people when they see something that is unsafe and have the power to be able to do something about it in that moment and that's how you really change safety statistics, it's not through Pitt's paper. We look to make sure that people understand that safety is not a work thing, it's a way of living and we encourage our people to bring in things that matter most to them, pictures, awards, certificates, maybe words that are worth protecting and we've got a notice board in each of our work sites where people bring in why they want to go home safely and when you start talking about safety from I want to spend time with my mates or my family or with my dog or I want to be able to go to football and contribute on the weekend. It changes the way people think about safety from it being a work rule to a good way to live and when people realise that the benefits last well beyond the work week you find that you get those changes in safety behaviour that really reduce statistics.


back to our channel. So I changed up the scenery a little bit. I came to the guest room because I feel like we never filmed in here before. But ignore the mess. Our closet over here is broken. Well, the door is broken. I got clothes all in here. This is like my storage room, and though I need to clean it up. I've been cleaning all weekend. So if you guys didn't know, I have actually been home alone for the first time ever. The guy have never been home alone by myself ever. This is the first time Bill is out in Sebring for the races this weekend. He gets back. If you guys see this, he'll already be back. But it has been a journey. It's been crazy. Like I can't believe like I faced one of my biggest fears. And my biggest fear is like sleeping alone in a house. I don't know, it just freaks me out. But we have security. We have, you know, alarm systems. Like we have so many things that keep us protected. So I felt very safe. And it was such a like good time to kind of have like me times. I feel like, you know, I have been down the last week, which is why I really wanted to like kind of like have a girls talk video with you guys. Because you guys are my family and I want to be more raw and open about things. And I feel like these type of videos are really good to be like real and raw. Because this past week, I have been absolutely down in the dumps. Like my motivation was at its lowest. And I think the main reason too was because I wasn't really tan. I have been outside tanning for this like last week. And I already am like getting bronzed up. Obviously I haven't been tanning my face as much because I will get into that in a minute. But I'm already feeling so much more confident. I am actually like really pumped for this week to like get ready again. To like get the motivation to film, to like be on camera.  And I don't know, I feel like I've just been very, very, very depressed. But honestly, it was really good that I was able to have this weekend to myself and kind of like just lay outside, you know, do some skincare things. And you know, just do things for me. It was honestly a very good relaxing weekend. And I am just so thankful for it. So yeah, I just want to be like open and talk about everything that's been going on and give you guys advice and like this kind of like us on FaceTime hanging out. And that's why I said I really like these videos. So make sure you give this video a big thumbs up. If you guys haven't yet, make sure you go down and hit that subscribe button and join the Marvel family. Hi, though. Wanna say hi to the Marvel squad? Oh my God, he's so cute right there. It's also super important to follow us on Instagram because this is where we get all of your questions. I asked you guys on Instagram to ask me questions for today's video. And you guys have had a lot of good questions that I feel like I really want to answer and talk about with you guys today because just feel like we haven't gotten personal in a while. So let's get personal. First question is, what is your skincare routine? How is your acne? How do you deal with that acne? Just everything's skin. So that is one of the biggest reasons my motivation was down. I honestly just forgot to mention that that was like the main focus. Ever since I moved to Florida, well, pretty much ever since I got off birth control, like I think it was like three years ago I got off birth control. That's when I noticed my acne was starting to rise and like I would get flare ups and I would get stuff on my chin, on my cheeks. And it was like to the point where it made me depressed. Like there was a point where I am just literally so distraught and like defeated. It was like to the worst since I've been out since I moved out to Florida. So I thought maybe it was like the Florida air, my body needed to adjust, which it could have honestly been all mixture of everything and like the hormonal, but when you get off birth control, which personally for me to talk about birth control, I personally had not a good experience. I will say my skin was the clearest it's ever been, but I just feel like birth control, you know, it works for some people, but I know in the longterm it's actually very bad for you. And that's why I personally got off cause I felt like I was dying when I was on it. Like I would have these weird like heart problems. And like I literally one day told Bill, I'm like, we gotta go to the hospital. I'm like, I don't feel right. But then I snapped out of it and calm myself down. But it was like to the point where I needed to get off this medicine. So that's when I, when I got off birth control three years ago, that's when I saw like my flare ups. This past year I've been battling it, but recently my skin has been pretty clear.  Let me show you guys. So I got a peel here. As you can see, I had a really bad flare up. I have some on my chin right here, I have some right here. My forehead's pretty good so far, but I did just get a peel to help like tone this down and get it away as much as possible. And I love my skin girl. She is absolutely amazing. And I'm so happy I found her here in Florida. If you guys haven't go check her out. She's the best. She's been helping me with my flare up acne. I feel like now I've been really trying to get my skin right. So pretty much I was using proactive. I use proactive for the longest time, but honestly for the long run, I know proactive is not good for your skin. It can cause like early aging. It's just, it's very harsh chemicals on your face. And I've been trying to like steer away from it. So ever since Friday I have been using face reality. I use the facial cleanser and then I use PCA. I'll use like the creamy cleansers and the toners and the serums and the moisturizers. I really like their brand. So far I really like PCA and face reality and I've heard amazing things about it. I also might be taking poor favor. I think that's the name of it supplements. It's like an acne supplement. I'm kind of looking into it more. I haven't officially decided yet, but that's pretty much my skincare. I'm pretty much going to really be trying to clear this up, especially before the wedding because I do not want bad acne during the wedding. So I'm going to try my hardest this year to get my skin right. Get back to a good skincare routine and pretty much every morning and night I do the same steps and also make sure you guys are adding sunscreen. Sunscreen is key to early aging and to make sure that your skin stays pure as long as possible. And I feel like I never took that seriously until recently. With the confidence level of acne, just know you're beautiful and especially in your 20s it is normal to break out. It is normal to have hormonal acne. It is normal to have cyst acne. Just everything, just know you are beautiful and you've got this. Like yes it's a struggle and yes it's hard and it feels like you're defeated. But just remember like everyone goes through it and you're not alone. And that's why I want to spread awareness to show like yeah I might wear makeup and I might cover this up. But underneath it yes I do have acne flare ups. I do have acne breakouts. Like this is real life, like this is what happens. So right now I'm in the process of getting it toned down. So I'm excited. So I kind of hope that helped anyone who is struggling with acne. This is a good question. Have you ever kissed a girl? Yes, I have kissed a girl before. I feel like back in high school when I would get super drunk with my friends. You know you give them like a pet kiss. I feel like that's so normal. I don't know I just feel like when you're really close to someone you like kiss your friends. And I've made out with girls before yes I have. But I never had that like sexual drive where I wanted more. It was mostly just me having a good time and like I would just kiss them and make out with them. And like it would just be funny for like a dare or like just to be funny. I don't know. That's just what I used to do in high school. I used to like kiss all my friends. So yes I have kissed a girl and I liked it. I'm just kidding. What color theme is your wedding? So we did talk about this in our last Q&A about our wedding. Pretty much the color scheme is gonna be like pinks, neutrals, kinda like boho, but also classy vibes. I'm in the process right now of getting my florist and he is like one of the best people in the Southwest Florida. And I am so excited to work with him. I'm so freaking excited. I hope everything goes great. He said he was available for the wedding. So I am so excited.  But pretty much my bridesmaids will be in this like pretty blush bubblegum pink. And I had all my bridesmaids pretty much in the same dress and shoes just cause I wanted to look seamless and I wanted to look really nice and elegant. So pinks, golds, neutrals, like you guys will see it all.  We got the greatest photographer and videographer like oh my gosh dreams are about to come true. And I think that's also why I've been breaking out. I've been super stressed with like wedding planning even though it's been fun. Do not get me wrong, it's been fun. But I feel like with everything going on, with traveling, with wedding planning, with getting content up for you guys and just everything, it's a lot. And I think that's why I have my hormonal acne because I have been constantly like trying to keep up with everything. But just to that's why I guys I have been feeling a lot better. I'm actually very motivated again and I'm really excited for building a home and get back into schedule. Any tips for a teenager girl having horrible period cramps? So I've struggled with really bad period cramps and I did go on birth control and that really did help. But I feel like as the mother figure I want to be to you guys, I definitely say depending on how bad your periods are stay away from birth control.  Like it was worse after I got off birth control and I was in so much pain it would knock me down. I literally couldn't even get out of bed. I had to cancel work when I would work on a normal like eight to five job. Like it was so hard. But for me what helps me is I take Advil I'll take like three Advils just for like the first day. And I take that every like four to six hours. And I would do like a heating pad, I relax. Working out will also really help you like just being active really helps your period in general it helps like the cramps. And I noticed like working out has really made my periods not as bad as they used to be. But you know like take it easy the first day. There's a lot of different ways that can help you with your period. There's definitely different pills. It just depends on the severity of your periods. But just know it is normal and it gets a part of life. And I tell myself every day it's crazy how I have to do this once a month for the rest of my life well until you get older but it's just freaking wild. This is a good one. What are some ways to stay clean down there? So it's crazy because I've been learning more about like you know self care and cleaning and all that stuff. And there's a lot of different like views on you know cleaning down there and how to clean down there. A lot of girls on TikTok talk about how you should only use water which yes I get that but I still feel dirty if I just use water. So what I use is a Summer's Eve. That's a very good thing to keep like your pH balance really well. And it smells so good. It's not really good to use like scented soaps down there because I feel like just throws off your pH balance. So if you want a good like product to use down there and use Summer's Eve it has changed the game for me. Like it is the best. But it's like there's so many different things like for different people and it's like crazy how some people can just literally go in the shower and rinse off with water and they'd be fine. Like I can never I still feel dirty. I have to use soap whether that's Summer's Eve. And you know for a while I was using my bath and body work soap which I know I'm gonna get roasted in the comments but I just need soap down there. I just feel like that's just nasty to me. I still feel dirty but Summer's Eve has changed the game. It's not even sponsored like that is like generally what I use down there. I think it's like the green bottle or it's like the coconut looking one. I don't know but it's most freaking amazing. Get your hands on one cause I'm telling you. You're down there will be very happy.  So I don't have my ring on right now because I just was outside canning. I showered and I just haven't put it on yet. But being a fiance has been the best. It's so crazy that I am one and just picturing like our wedding and like I've dreamt of this my whole life and it's so crazy that I'm about to literally be a wife. Like I don't know, it's just wild. I'm so excited. It's been so much fun. I'm trying to soak in this year of being a fiance because I really do believe that Bill is the person for me forever and he is the person that I have been waiting for and I just love him so much. He's so caring and loving and I feel like every woman deserves a man like that. Every woman deserves someone who puts you first puts your priorities first and just makes you feel loved but also you gotta do the same thing for them too. Yeah, it's been a journey and I have been loving every second of it. Is it normal to get an acne flare up on your period? Yes, that is like the main source of flare ups is your period because you're going through hormones. Your hormones are out of whack. It's so common and that's when I get really bad acne is during my periods. So yes, that is totally normal. How are you so confident in yourself? It is so hard for me. It's crazy because I might look like I am super confident but at the same time there are days where it is hard. Like there's days where I look at myself and I feel like I am so ugly and I feel like I don't look good enough. I feel like even when I go to the gym like I haven't been seeing results it's just like mental things that you put yourself through sometimes and that is normal but then you come out of it and you're like, okay, you know what? I am beautiful. I am seeing progress. I'm feeling great. I look great and just start loving yourself more and it is okay when you get down on yourself and you feel like you're not the best because that's normal. That's human. We stare at ourselves every single day. So we nitpick everything about ourselves but we have to remember that we are beautiful. God made us who we are and to love ourselves more because I feel like that is super hard and I struggle with that sometimes and just lately I have been eating better. I have been doing things that have been making me happy even just going the lay outside for 10 minutes. Do things for self care and like for your mind because when you sit and do nothing that's when your mind wanders and when you're active and you stay active honestly it makes life so much more happy and you're not sitting there picking away everything about yourself and just know you are beautiful. Every size, shape, everything. Anything about you is beautiful and you just have to keep reminding yourself that. That's pretty much how I stay confident. Obviously some days are better than others but I just try to do things to keep my mind from wandering. Here's a good question. How was your high school experience? What it's like in a public versus private? I love you. I love you too, Casey. I was in a public school and my high school experience was, it was interesting. I did have a lot of friends. I had a lot of different groups but I realized that that was so much drama. If one group was fighting, the other group was fighting or you would start tag teaming on someone and it was just so toxic. My best advice is to have a small circle. I know in high school you have like those popular girls who are friends with everyone. Trust me, it is not worth trying to be up there because most of the time those people that are up there when they get out of high school they are the same as you. They're not popular anymore. They're going to literally you guys are restarting life and going into your career or whatnot. So try to remember you don't have to have a big circle to fit in. Like even if you have one friend, I go back to school. I would have one solid friend and I would be content and I feel like I was so involved with the wrong crowd that it honestly was super toxic and I'll tell you I had a good high school experience too. Like it was fun. I had a lot of fun like hanging out, doing things with my friends and going to events and doing stuff like that. Like it was fun, but I do not miss high school. I don't miss anything about it. I don't like how toxic it was. I feel like it was a waste of time. It just drags you down. I know school now is even worse. I know kids are worse now.   So they're going to nitpick everything that you do because they don't want to see you succeed. But you know what the best karma is is showing them that it doesn't affect you and they will go off their own ways.  I wish that was something that I did when I was in high school.  Like it's crazy seeing the girls at school now like crop tops, like wearing all makeup. It's just crazy cause it's never used to be like that. So yeah, that was pretty much my high school experience. It was interesting. How do you fix relationship if you get into a disagreement? So the biggest thing if you guys get in a disagreement to hear each other out and say, you know what? I'm sorry that I made you feel that way. I will make sure next time I don't do it again. Just like hearing the other person out and not trying to fight back and be like, no, you said this, no, you said that. Like you guys have to level with each other and say, okay, this is the root of the problem. I wasn't perfect in that situation and you weren't perfect in the situation. So let's come together and figure out what we can do to fix that so that it doesn't happen again. And you know, that's a very good key of a disagreement is communicating. If you have to step away for an hour before you come back and talk, it's definitely not good to talk when you're super mad.  But you have to take a step back, realize what just happened and then come back together and solve whatever the issue was. And that is pretty much how me and Bill go through our disagreements. We just come together and we discuss what we did wrong and we try to fix it for next time. Okay, this is gonna be my last question. So I feel like I've been rambling for ever now. Tips for friendships in your 20s. And I feel like this is a very good question to leave off on. For me, I've come to my life where I have finally found the people in my life that I wanna surround myself with. And I feel like it's so hard to find a good, solid friend.   And I feel like I have found the best people in my life and I am so thankful for that. I'm surrounded by people that are motivated and who have the same drive as me and who lift me up when I feel down, who are literally like family to me. So it is hard to have relationships in your 20s, but when you find the right people, it's the best time of your life. Like it really is to have a good, solid friend. And I'm just so thankful for the people that I do have in my life and the support that I have with them and the time that they take to make sure I'm okay. And it really does feel good because I feel like I've struggled with friends in the past and people always come and go and it sucks. It sucks a lot, but I feel like I'm at that place in my life now where I feel very content and I'm very happy with my life and the people in my life and I wanna hold them close and tight and I'm very thankful.  If a friend cannot be happy for you and because you accomplish something and they try to be like, oh well, this and this and this, they're not good friends.  That is the key to a good friendship. It really is. But you guys, I hope you enjoyed today's video. It felt really good to kinda just talk and kinda have a house to myself to talk because I feel like some of them build around me, I get like nervous. I don't know why I do, but I do. And so it just felt honestly really, really good to kinda just have a little chat with you guys and just some of you guys with questions. I wish I could answer every single one so I could talk for hours. But I hope that was good. I feel like I'm not the best at communicating or talking sometimes, but I've been getting better and I am just so thankful that I have you guys as my family and so thankful for each and every one of you for all your support and love. I'm super excited for Bill to get home. Stay tuned for all the videos this week. Make sure you guys comment down below video ideas that you guys would like to see on our channel and we will see you guys in the next video. But until then, peace, love you guys.


Live from Barcelona, Spain, it's theCUBE. Covering Cisco Live 2020. Brought to you by Cisco and its ecosystem partners. Welcome back to Espanya. This is theCUBE, the leader in live tech coverage. We're here in Barcelona at Cisco Live 2020. Inside the DevNet zone, this is day one. Eric Herzog is back to talk about cybersecurity. He's the CMO and Vice President of Global Channels for IBM Storage. Good to see you again, my friend. Dave, Stu, thank you very much for having us. We love being on theCUBE, and you are the leaders in IT information. No one better, especially for real time. Thank you very much for that. So we're going to talk cyber, very important topic. It's a big tailwind for Cisco. IBM, obviously a big player in security. It's on every CIO's mind. What's your angle, though, in storage specifically? Sure, well, I think one of the key things is that when people think security, they think keep the bad guy out, and when the bad guy gets in, chase him down and catch him. What they don't realize is sometimes it could be a day, a week, or weeks, until they know the bad guy's in. So how are you going to protect yourself when all your valuable data is exposed like that? And then, when you do have an incident, particularly malware or ransomware, how do you come back to a state where you know you have good data and you basically don't have to pay the ransom, or in the case of malware, the data is good data? So we can help on both fronts with the things we've done with our cyber resiliency play inside our storage portfolio. So compliments and gives IT and the CSO, as well as the CIO, an overall comprehensive security strategy so that when they're in my house, how am I keeping them from somehow stealing it even though they're in the house? That's what we can help. Okay, I see where you're going here. So, and by the way, I've seen stats that say it's upwards of 200 to 300 days before people even realize they've been infiltrated. And then it becomes a matter of, okay, how do I respond? Now you've got malware, not only malware, but you've got ransomware. And so, let's talk more specifically about how you attack that problem. Do you help me sort of find when something's been penetrated by looking at the backup corpus? So what do you, analytics? What do you guys do? So we do a couple of things. First of all, we do have in our spectrum protect suite, which is our modern data protection, does the backup, et cetera, is we can detect anomalous activity in backup data sets, snaps and replicas. We use AI and machine learning to understand if that's a new occurrence. So let's take an example. The backup data set runs from 11 a.m. to 1 p.m. At midnight, you have all kinds of weirdo backup activity. Why? Because if you're malware ransomware, you want to get to the secondary data sets first before you attack the primary, otherwise they'll just go back to the secondary. Yeah, they'll lose some time, but they'll go to that. So we can detect that and alert the backup admin, the storage admin, whoever you tell us to do. Then, over time, if that process changes, and so you're always going to have certain activity at a time that previously didn't, we learn that and stop sending alerts and stop sending notes. And obviously, we don't say we think it's malware this or ransomware that. What we do is alert them to anomalous activity as an attack could be started. So that's just one of the things we do. We have much more that we do in cyber resiliency, but in that case, monitoring and detection, threat detection, we help do by looking at secondary data sets. Yeah, Eric, I wonder if you can bring us on to the organization of your customers, because is this something that just the storage team buys or are you being bought in, like you said, by the CISO or some other organization and once it's sold then, how does this play out inside the organization? Sure, so it's a hybrid strategy. So let's take, for example, we have a thing called Safeguard Cop. You've had it for 18 months now in the main frame. Wildly successful, wildly successful. Not just with the new Z, but with the old Z14. And the reason is we would go into the storage guys and in the Z world, money was tight and we'd say, what if we could help you protect against malware, ransomware, or even internal threats. We have dual access control capability from an internal management perspective. They said, really? And then the storage guys actually took that, the security team and said, guess what, we can help you. And they said, oh my God, and they gave money actually to the storage guys. In other instances, we approach through the security side and in fact, one of the things we've done is talk to a lot of our partners who have a security practice, a storage practice and never thought about thinking of them in a holistic fashion. So from a partner perspective, it gives a more holistic solution to the end user. They sell, keep the bad guy out, track the bad data. Oh by the way, did you know that IBM's flash system will do data rest encryption with no performance penalty so you can encrypt everything on that and there's no penalty, it's at line speed. So if they're there for a week or 200 days or whatever, that data's protected because it's encrypted. So that's more of a, the partner's work in a holistic security strategy. I mean, IBM is a long heritage in security. RACF, all your old main framers, Resource Access Control Facility was the cold standard back in the day and really set the roadmap for best practice. So obviously things have changed a lot. What is best practice today? Are you recommending customers set up air gaps? There's certainly tooling, but more tooling is a challenge for people. How would you see in customers combat the problem? So what we do is we look at it from a storage perspective. So we have a couple of things. A, we have air gapping to tape and air gapping out to clouds. So our spectrum virtualized sits on-prem and off-prem. We can do air gapping with our spectrum scale product, which AI and big data again, put it out. IBM could all put eventually a snap or replica out to a cloud, gives you a logical air gap. Tape will work with anything, file block an object, then you have a physical air gap. So that's one aspect. The other thing, of course, they had mentioned already is encrypting. We can encrypt file block an object data. In fact, we can worm it. So make it immutable and then encrypt a worm. So, and in fact, with our object storage because of the way we do our hashing and the way we do our eraser encoding and the way we hide the keys, we basically can make it almost non-crackable. So file block an object, what we do to prevent and then the air gapping. And the last thing we do is incidence recovery. So they had an incident to go back to a known good copy. So the safeguarded copy, we can basically mount instantaneously snaps or replicas. They would do a ring fence network because obviously they do it online with the real network, they could crash it or compromise. So you set up a ring fence network and you keep bringing back the snaps or replicas and look it at, right?  Okay, we can't use that snap. And it's very easy to do. We can automate the process. They have to put the ring fence around and they can go back to as many copies or replicas they have whether it be the file side block or object. So that would help in incident recovery after they know they've had an attack. They've cleaned it up. Now you go on and make sure that your secondary data is good data before you restore it. Otherwise you could put the malware ransomware right back into what you had. So both recovery side, protection side, on-prem with encryption and then obviously with air gapping protection but if you will out of house either physical or out to cloud. Eric, help us connect the dots between what you're talking about and the audience here at Cisco Live. Obviously networking people, there's always a little bit of security inside there. So help us understand how these go together and the reception you get from them. Well, again, the reception is very good because what we do is their look, Cisco's looking at doing all the network security. We're a partner of theirs. Again, it allows them or their channel partners to go in and say, here's a holistic strategy. Keep the bad guy out. Okay, here's what you do to track the gag, gag down. By the way, here's what you do on the network side with our Cisco gear, but here's what you can do with the storage here. So partnering with a holistic strategy to the end user, right? And say, here's what we do for the network. Here's what we'll do for the storage. And of course it doesn't step on each other because we're looking at the network traffic. We're looking of course at primary storage and secondary storage and actually hybrid multicloud storage as ways for the protective data. So it's completely a complementary play. By the way, the other things that IBM security division does both to keep the bad guy out and track the bag are also coming. None of these things step on each other. It allows you to have a truly holistic strategy because right now network security is semi-thought about. Storage security almost never thought about. So it's like, let me give you a whole strategy that's going to work, bring the data back, help you understand it, keep the data from being stolen, immutable copies. If they get there and they steal the data, encrypted data, so all kinds of strategies that networking guys do. So it allows the end user or certainly the CIO to go to the CSL or the chief legal officer to say, I got a holistic strategy. Yes, I'm good. It's not an if question. It's a win. So here's what I'm doing to reduce the incidence time. Here's what I'm doing to keep the bad guy out which is not what we do in the storage division. Here's what we do if they're in to keep the data safe. So we know if it gets stolen, it can't be used. And by the way, once we clean up the malware ransomware, we need to get you up and going as soon as possible. Mr. CEO or CFO now or the line of business guys and we can do that without having the data being compromised or the data being bad data. It's interesting to hear tape as part of the equation, right? Keeps coming back, but it is part of the best practice. So there's air gap, but tape kind of the last resort. You don't want to really recover from tape, but if you have tape in an offsite location, if it's a lot of data, it's fast to move because as you put on a truck, it may be an RPO issue. But are you seeing that certain industries, financial services in particular, maybe are or certain companies are mandating that last resort? So what you're seeing with tape overall is for IBM and Renaissance, both inside the data centers. So from that perspective, think enterprise accounts, the global fortune 2000. And from that perspective, it's partially about the air gapping. It's partially I've got gobs of data. What's the cheapest way to make sure I got a backup copy? Then we're also seeing a huge take up with hyperscalers and cloud providers. So you have several of the top 10 cloud providers on the planet that when you buy their archiver cold store, it actually goes on the IBM tape lever. So you have a cost angle, which is independent of the cyber resiliency side. Then you've got the cyber resilience side. And for us, when we're talking bigger accounts, so think enterprise up to that fortune 2000, they're probably going to do different things for different data sets. So certain things might be snapped out to the cloud, other data sets might go out to tape. And there are regulated industries still like healthcare, finance, and obviously the government itself where sometimes tape is still like mandated. And so even though it's legacy, the bottom line is they need it. And then once you get in there between the cost angle of what they can save, and the fact that, oh wait, I thought just back is a, well wait, what about malware and ransomware? And by the way, a smart company's going to use a hybrid combination, so they'll have some stuff going out to the cloud. They may have on-premises, again, our safeguard copy on the mainframe is actually can be on-premise. So you've got 500 immutable snaps that are encrypted, and then you keep going back to find the one that didn't have the malware ransomware. So it's probably a combination strategy, even on the storage side, which would include tape, what we could do for a file block and object on flash. We could even do it for if someone's got older disk or want to use second, like IBM Cloud Object Storage is mostly done on disk. Well guess what, now that older data is encrypted, it's wormed, it's protected, by the way, we can air gap IBM Cloud Object Storage out to the cloud too. So I think it'll be a very comprehensive strategy based on application workload use case, value of the data set, and obviously with things like tape and backup to the cloud. You have a secondary use case, which is not just about the security, but I need to backup the data, in case there's a fire. Or me being the Silicon Valley guy, I need to go out to tape, because there might really be an earthquake, and as great as IBM arrays are, or any of our competitors are at, because we, as you know with our software, support all our competition, those arrays are going to be crushed when the building falls down in Silicon Valley, so you might need to have tape for cheap backup. So there's a lot of different angles that involve not just cyber resilience, but the combination of cyber resiliency, and really data reliability and data safety, that are independent of the cyber attack worry. And you can combine them, because of the way we put this together with our technologies. Yeah, you're talking about a comprehensive strategy, which is very important, because this has become a board level topic, and it's no longer, I'm sure it still happens in many organizations. So yeah, check off item. Yeah, we do that, we do backup to whatever, cloud tape, check off. But in many organizations, if not most certainly publicly traded organizations, it's a board level conversation, and they really do their homework. Down to even the testing, although testing is a little tough, right? It's time consuming and cumbersome, but definitely thinking through, the board wants to know, what happens if, okay, what about this, what about that? They've experienced a lot of different permutations. So it's, again, not just a check off item anymore, you can say, oh yeah, we comply, it's really no, we need something that actually works, because we know we're going to get hacked. Well, and that's part of the reason the safeguarded copy on the mainframe side has done so well. Companies that are using mainframe, it is the most mission critical workloads, the highest transaction workloads. So in the financial sector, in the government sector, in some of the big giant manufacturing or retailers, they're running mainframes, and they have been for years, and they're not stopping. And so for them, system uptime is an issue, security is an issue. So the safeguarded copy for us has really been really a grand slam homerun product to use a very US centric term, but maybe a sixer if you like cricket, or it was a try if you like rugby, but for all those various sports, it's been very successful because of what they use that mainframe for and how critical that data is. So it's been very successful in that perspective. There we go. How about you obviously sharing a lot of knowledge specific to storage. I said before IBM's got a long heritage in security. How do you collaborate with the other security pros at IBM? How much of that sort of filters into storage and back out? So what we do is we make sure that they're aware of what we do. They're looking at some new things that I can't disclose around security that would make places for people to go and practice if you will and do some other things. We're going to be involved in that program, which allows people to try things out if you will in a very secure way. And some that IBM's going to do across storage will be part of its security and some of the other divisions, but we haven't yet rolled it out, but it's something they're working on that will be part of. And then obviously there are many times in the big accounts where the security division in there, the storage guys in there, but the account team knows that there's both issues and bring us together inside of a big account. So that happens as well more if you will from the sales side versus this official program that could be launching shortly later this year. So wrap it up with what's going on at Cisco Live. What are the conversations like with customers? What's IBM all about here? So for us, our big thing has been about both our hybrid multi-cloud technology, which allows seamless move data back and forth. And we have a product called the VersaStack, which incorporates our award winning flash systems. So we position it either standalone or with the VersaStack. VersaStack in the booth. And then also obviously cyber resiliency. So I just presented yesterday on hybrid multi-cloud and then today I presented on cyber resiliency and how those things work together and what we do with Cisco. So it's been a very good show and very successful for IBM here at Cisco Live. Good job. Well, you guys are great partners. Thanks for coming on theCUBE. Love the shirt as always. Eric Kurtzog, IBM, thanks so much. Thank you. You're welcome. All right, keep it right there everybody. We'll be back with our next guest for Cisco Live Barcelona de Valente with Stu Miniman for John Furrier. We'll be right back.


So in this lecture so far, we've learned how we can solve quadratic equations by using factorizations and the zero product property. And I really like this technique. It can be really fast and very effective, but it depends on one thing. Can we find a magic pair? That's what's necessary to do this reverse foil process. And there's two issues of that. One, if the numbers get big enough, there actually could be a lot of different factorizations. So there's a lot of possibilities to check as you're looking for the magic pair. And then there's also the unfortunate reality that sometimes the magic pair doesn't exist. We cannot find it. Maybe the hydra ate it already before Hercules got there. I don't know. But the magic pair doesn't exist and we can't find something that doesn't exist. So what we're going to do is start introducing an alternative method for solving quadratic equations that can be very useful. And it's the idea of using square roots. Like we talked about with inverse functions, the square root is essentially the inverse operation of the squaring function. It's not exactly true because square is not one to one. But as long as we keep track of the fact it's not one to one, we can use the square root function to help us out here. So for example, if we have the equation x squared equals P, we can set that equal to zero and we can't factor in the following way. So we have x minus the square root of P times x plus the square root of P. I mean this is really just using the difference of squares here where we're recognizing that even if P is not a perfect square as an integer, it is a perfect square as a real number. Every number will just factor as the square root of P times the square root of P. And so therefore the solution is going to be x equals plus or minus the square root of P. The idea is if you have x squared equals P, you can take the square root of both sides performing the inverse operation to the square. But because the square is not one to one, we have to compensate for the fact it's not one to one. There's a positive solution and a negative solution. As much like we did with absolute values, as long as we remember there's a positive negative, then we'll take the square root of both sides and we can go from there. Now if your P value is greater than or equal to zero, you'll take the square root and you'll get a real solution. If P is positive, there'll be two solutions, plus and minus the square root of P. If P was zero, you'll just get one solution, which is zero. But what happens if P is negative? If P is negative, you'll be taking the square root of a negative number, which is not a real number, but it is a complex number. So you won't have any real solutions, but you will have complex solutions that might involve some imaginary components. So consider this one right here, x squared equals five. Well to solve this, we can take the square root of both sides, in which case you're going to get plus or minus the square root of five. That would be the solution to this equation. Now we probably should write them out separately, the square root of five and the negative square root of five. There are in fact two distinct solutions here. How about this next one, x equals negative nine. Well if you take the square root of both sides, you're going to get x equals plus or minus the square root of nine. When you take the square root of a negative number, that just means it's imaginary. You get the, you get i times the square root of nine, which is square root of nine is three. So you're going to get plus or minus three i. In other words, three i and negative three i. And so even though the solution is non real, we're going to allow it in this chapter. We're going to, we're going to consider all complex solutions to quadratic equations. What about, what about part C right here equals 16? Well the fact that we're squaring a binomial as opposed to just x itself doesn't really hinder us much. I mean, this might be relevant if we're graphing something, maybe your function just got shifted to the right by two, whatever. Well, if we take the square root of both sides, the left hand side, when you take the square root, it'll cancel with the square giving just x minus two. And on the right hand side, we're going to get the square root of 16. Just remember to take the plus or minus 16 there. This gives us plus or minus four. And so then to solve for x, we just have to add two to both sides. And we get x equals two plus or minus four, which there's two different numbers here. There's going to be two plus four and you're going to get two minus four. So we see that x equals six and negative two. Nothing too big about that. Not a big deal. Kind of like what happened when we did stuff with absolute value. Now, this was really convenient that this thing was factored as x minus two squared. Even though it wasn't equal to zero is equal to 16. All right. The reason why we were able to get good past this is we weren't trying to say that, oh, if the factors are if the product 16, I know that the factors have to be four and four or two and eight or something. We actually want to stay able to take the square root of both sides. Alternatively, if we had this thing multiplied out, it would look like x squared minus four x plus four equals 16. And, you know, if you move this the other side, we could have tried to solve this by factoring x squared minus four x minus that'd be minus 12 equals zero. You could try to factor that and you would see that factors of negative 12 are going to be positive six and positive two, which gives us the solutions of six and negative two. We could have solved that one by factoring, but it was kind of convenient that we had that perfect score on the left hand side. You're just able just to take the square root. It was a lot faster. So when you look at this one right here, x squared plus six x plus nine equals 12. You know what, we could subtract 12 from both sides, put in standard form, x squared plus six x minus three equals zero. We could try to do that, but it's like, huh, I tried to factors of negative three to add up to be six. I don't think I can do it. I could take three minus one. That's only two. Or I could do negative three plus one, which is a negative two. That's not going to work. We could find a magic pair right there. But if you look on the left hand side, x squared plus six x plus nine, I can't help but notice that this is in fact a perfect square trinomial, a perfect square. And as such, it would factor as, because notice your first term is a perfect square. It's x squared. Your last term is a perfect squared, which is three squared, three times x. If you double that, you get a six x. This is a perfect square. It would factor as x plus three squared is equal to 12. And so even though I can't solve this with a magic pair, I could try to solve this by this method of squaring, square rooting, I should say. Take the square root of both sides. We get x plus three equals plus or minus the square root of 12. Now the square root of 12, 12 is not a perfect square, but it does have perfect square divisors. 12 is four times three. So this becomes x plus three is equal to plus or minus two square root of three. And so then when you subtract three from both sides, you get that x equals negative three plus or minus two root three. So you're going to see that the solution to this, to this quadratic equation, it has irrational solutions. It has this square root of three. It's not a whole number. It's not even a fraction. It's this irrational number. And so we're only going to be able to solve quadratic equations by factoring. That is the magic pairs will only exist basically when the answers are whole numbers or fractions. Integers are rational numbers. But if you have irrational solutions, you won't be able to solve them by factoring. But this idea of the square root, but it only works if you have this perfect square right here. Now it turns out that is not a huge restriction to us whatsoever. Because if we do not have a square root, we can force it to be a square root. We can give the quadratic equation an ultimatum. You be a square root or else. And it turns out we always get what we want. And we'll talk about this more in the next lecture as we talk about completing the square.


All right traders welcome back. My name is falso from cyber trade university I want to catch up and do a quick video on Kodak if you've been watching our channel And you've been watching us on our morning cyber group meetings Just click on the bottom if you haven't done already like us on the bottom and you'll be able to watch them I'm just gonna bring one over here pretty close with you This was yesterday's video that I'm bringing up really quick and you could see Kodak was up about 325% you could see we also traded Fran, you know views are starting to pick up Got a lot of likes. I don't know why anybody would not like it but but this was actually yesterday's view and Want to kind of talk about what's going on right now? And if you basically had been watching that video, here's the second part you could see Kodak now when we watched it It was down around it looks like Kodak reopened up again. Yep, and from having that price right there at that price You could see it right now is at 30. It just opened up. It got halted now When you look right here, it's gonna bring this up really quick Some of the great tools that we use at Cybertrain University is we use the Nasdaq book viewer You could see big block buyers coming up over here keep bidding it up. Look, it just got halted again It's at $31. It looks like the CEO is coming on Fox business right now Which probably is gonna cause the stock to move pretty well. You can look up the news I'm not here to give you the news But it was touted big what's going on with the deal that the governor Cuomo signed with the president to get Kodak to do to take a lot of the work away from China as in with the medical stuff people probably don't think of Eastern Kodak You think they would still do the polar rights, but no, they're there. They became a very big How can I say conglomerate? They they're in a little bit of everything and you could sure enough is doing pretty well But what I also want to point out is I want to bring this up You could see right here Kodak is the stock right here over the course of the day Started oops wrong stock. I apologize. Not the wrong one and the stock is hold it Just bring this up right here So you can see the stock got halted you see blanks blanks blanks blanks that means the stock got halted several times Oh actually more one two three four or five six times the stock got halted today And we've been trading the stock all the way down and let me bring this up here for you All the way down here in pre-market We've been trading it I'm only going back to 915, but if I go to my trading room you could see right here And let me bring this up here's our pre-market at 758 in the morning and you could see Kodak is right there And you could see that we're talking about Kodak a lot of students at this is an hour and a half before the market opened up And we've been trading it ever sinks grant worth watching nice cold this morning Resistance levels at 15. You could see people just calling trades over and over again I was up about a buck a buck three and Kodak still climbing. This was at 825 I could scroll all the way down here till the morning and you could see Kodak Kodak Kodak Kodak and the crazy part we're trading at 17 the stock is already at 32 and It's still climbing. So when it comes to trading cyber traders and fellow traders date trading It helps you to become more of a swing trader more of an investor. There are so many stocks like Kodak All right, so please don't don't think like this is the last straw or whatever it is But if you like that video I posted yesterday and you want to know how do we know the stock was going to go up? Who ran it up?  In the morning and get this watch list If you want to learn how to trade today's markets because with today's corona virus and what's happening in today's world Working from home depending on a stimulus package. What do you want to do? That's a waste of your time Go out there because this one trade probably could have paid your whole Probably yearly income salary just on this just on this one stock alone But don't worry. There's a lot more like Kodak's gonna happen and guess what I got news for you There's gonna be more Kodak's out there because after because you are coming stepping into one of the biggest and most best Hate the word best but biggest catastrophes in the trading industry and unfortunately catastrophes do make opportunities if you've been around the financial crisis two two thousand if you've been around the the internet bubble if you've been around the The flash crash 9-11 and now the corona virus guess what this is gonna be around for a while So you better stop learning now so you could benefit and make and jump into stocks like Kodak Thanks for watching like us look forward to seeing you watching some upcoming more videos here at Cybertron University Happy trading everybody


The following message contains distressing scenes based on hate crimes prosecuted in Wales. Actors have been used and details changed to protect the victims. Being attacked online for defence and our friends hurt. We shouldn't have to hide who we are or who we love. Being at home used to make us feel safe. But when people threaten you online it makes you feel anxious. Not being able to put a face to our attacker made it worse. I don't think many people realise that the police will take this kind of hate seriously if you report it. Even if it happens online. All we want to be is who we are and love who we want to. Love is love.


Okay, so to start out the pack that everything is going to go in is a DG3 from Crossfire. It's a three-day 55 liter pack. On the pack I have a little ferro rod attached to make some fire when needed. Inside the pack I have this blaze orange dry bag. This doubles as a signaling bag and it's the dry bag that my sleeping bag goes in so it doesn't get wet. A sleep pad because I'm a sissy and I need this in order to sleep in the field I found out. And a sleeping bag in the stuff sack. The sleeping bags I think rated around 30 degrees so between that and layers I anticipate being plunky warm. For food and water I have nine MREs. These are the civilian kind, not the full military kind so they're already pretty stripped down. So I won't be stripping those down, leave those as is. For water I have a total of seven liters. So I have three here in the bladder. I have two extra quarts. One with a canteen cup for heating up some of the food, for heating up drink mixes, whatever as appropriate and as able to do that. So two of those and then I have two other liters of water that will be in my fighting mode which we'll cover a little bit later. I also have peanut butter because that's always good to have in the field. I have a bunch of little snacks here, a couple of cliff bars, a protein bar, a couple packs of skittles. For my cook kit I have a fire driving stove as mentioned for the canteen cup with three cells so not enough for every meal obviously but just enough to give you a little morale boost. The lid for the canteen cup, a little rag to light up the cup and a lighter wrap and duct tape. That all goes inside its own dry bag so that stays separate and dry. I calculated about a half gallon of water per day. In case that I'm off of those speculations I do have a dirty water bag along with a water filter so that I am able to make more water in the field. A couple of personal care items. I have a couple of small bungees and small zip ties. This is for a repair kit in case something breaks or needs to be reattached or fixed in the field. This is a field repair kit that came with a bag. It's a couple patches, a couple extra buckles. So if anything goes wrong with the bag that can be readily fixed in the field as well. This is just a small boo-boo kit. Some band-aids, some hand sanitizers, some chapstick. Just general take care of your stuff. Continuing on with personal care I have some body powder, some mouthwash, a second chapstick. And then this is some lucho tape that I have. That's great for cuts, blisters, whatever. That stuff is absolutely magic. It will stop blisters in the heartbeat. My uniform is permethrined so is my gear. However, I also have a towelette here that's a deep woods towelette to keep the bugs off you although it's cold. So hopefully that won't be needed. I have just one hands warmer in case it gets real cold and or you need to sleep at night in order to stay warm. That goes great with your pockets or your sleeping bag.  Extra batteries, I have extra double A's, extra triple A's and extra CR123's. That goes with all of my equipment here to make sure it stays up and running and is functional. And if anything goes down we can keep it running. That goes inside its own dry bag so those don't get ruined. This is a multi-cam pack cover. This does not actually fit over the pack when I have the bedroll attached. However, to keep my pack protected from the rain at night and or when we're able to stop moving. If I'm able to take that bedroll off this goes great over the pack and is super waterproof so it protects the bag. I will be taking the poncho that's laid out here as well for some kind of low-grade shelter and or extra rain coverage because we're anticipating rain. I do have a hang-up hair cord in here. I also have some extra tent stakes so that I can stake it down and make some kind of low shelter as would be situationally appropriate. I have a watch cap because it's expected to be cold. This is a sniper veils kind of green tan on one side, woodland on the other. This is just to further camouflage our position and or gear. This is an e-tool. I have an e-tool of course to dig the trains, further camouflage our position and any other general field use. For PPE gear and uniform, I have eye protection. I have a set of green gloves. I'm going to wear my green cover out. And then I went with a multi-cam uniform because that seems to blend in best with the environment. I have Gore-Tex waterproof boots because again cold wet and rainy and then I'll be wearing my knee pads out. For extra layers and water protection, I have a Gore-Tex top and bottom. Gore-Tex top I will wear out. Gore-Tex bottom I'm going to pack for storage. I also brought an extra waffle layer for when it gets cold at night. I am wearing a thermal layer underneath my uniform, just the top not the bottom but I have a waffle layer top as well. I have a thermal layer bottom again in case it gets cold at night and or when we're stationary not moving around a whole bunch. I need the layer up to stay warm so you don't freeze. I have three pairs of underwear, three pairs of socks, and then just two extra t-shirts. That all goes inside its own right. For navigation purposes, I have a map case along with a map of the area. I have my lens static compass. I have pace-count beads attached to my gear and I also wear my watch. This is my extra set of webbing. This is totally stripped out right now except for my iFat that is on my webbing. It's just a standard iFat with the scissors and two tourniquets that's on the webbing. Everything else is laid out. I lied. The other thing I have on my webbing is some black athletic tape. That's for general field repair stuff and or cuts, scrapes, whatever. Anything you would need tape for that stays on my kit all the time. For a fighting load, I have a 16-inch rifle, tourniquet on the gun, sling-attach the rifle, optic, light, and a can. This rifle is a real rifle and I will show you the empty chamber right now. Real rifle. Look. I have seven magazines for the rifle, one in the gun, six on the kit. That way if we need to leave we can mag-dump and run away. In here is a PBS-14, so this is for observation at night. I'm not going to wear a helmet or anything to attach it to. This is just to be able to have a handheld to look through at night to observe. I purposely did not bring a binoculars because this is in a wooded environment along a trail, so visibility is expected to be limited so we do not have binoculars laid out here. Other items I have in my fighting load are another lighter wrapped in duct tape, a little camouflage compact so that I can touch up my base camouflage in the field, and then a right in the rain notepad and pen so that I have something to record my salute report on. Last two items that go in the fighting load are my knife. It has a straight back edge so that I can use it for the ferro rod, attach the pack as needed. Also just for general field use and stabby-stabby use. And then a red headlamp so that I can see at night, work under my poncho, etc. Another item I did forget to mention is I do have a rifle cleaning kit. This is just a rod, lube, brushes, standard little Alice rifle cleaning kit, along with a rag to clean off the gun, wipe off solvent, etc. Okay, that's my entire loadout for three days. Let's see what it looks like when I have it all on. This would be my salute report. This is Bravo 13, standby for a salute report. We are located at 86904875, break. The size of the element is a four-man fireteam, break. They are patrolling in an unalert fashion, break. The enemy is located at 86804895. They are heading in a southeast direction, break. They are suspected Durka Liberation Front. They have black and tan uniforms with boonie hats. They are clean and well-kept, break. The time is 0331, break. Their equipment are three SKSs, one drum top MG. They are all wearing webbing gear, no packs. Break. My only remarks is that they are patrolling in a very unalert fashion. They are assuming they are safe and they are not expecting a fight or expecting enemy us to be in the area. Out. Thanks a lot, much appreciated. Do brave deeds and endure.
