Hi children, my name is Mansi and I am going to help you solve the following question. The question says, prove the following by using the principle of mathematical induction for all n belonging to natural numbers. 1 into 2 into 3, there is 2 into 3 into 4 up till n into n plus 1 into n plus 2 is equal to n into n plus 1 into n plus 2 into n plus 3 the whole divided by 4. In this question we need to prove by using the principle of mathematical induction. Now before doing the solution to this question we see the key idea behind the question. We know that the principle of mathematical induction is a specific technique which is used to prove certain statements that are formulated in terms of n where n is a positive integer. The principle can be explained with the help of two properties. If there is a given statement P at n such that first P at 1 is true and second statement is true for n equal to k where k is some positive integer, k is true, then statement P at k plus 1 is also true for n equal to k plus 1, then P of n is true for all natural numbers n. Using these two properties we will show that statement is true for n equal to 1, then assume it is true for n equal to k, then we prove it is also true for n equal to k plus 1 hence proving that it is true for all n belonging to natural numbers. Now we start with the solution to this question. Here we have to prove that 1 into 2 into 3 plus 2 into 3 into 4 up till n into n plus 1 into n plus 2 is equal to n into n plus 1 into n plus 2 into n plus 3 the whole divided by 4. Let P of n be 1 into 2 into 3 plus 2 into 3 into 4 and so on till n into n plus 1 into n plus 2 be equal to n into n plus 1 into n plus 2 into n plus 3 the whole divided by 4. Now putting n is equal to 1 P at 1 be 1 into 2 into 3 that is equal to 1 into 1 plus 1 into 1 plus 2 into 1 plus 3 the whole divided by 4 that is equal to 1 into 2 into 3 into 4 the whole divided by 4 that is equal to 1 into 2 into 3 and this is true. Now assuming that P at k is true P at k be 1 into 2 into 3 plus 2 into 3 into 4 and so on till k into k plus 1 into k plus 2 be equal to k into k plus 1 into k plus 2 into k plus 3 the whole divided by 4 and let this be equation number 1. Now to prove that P at k plus 1 is also true we consider P at k plus 1 that is 1 into 2 into 3 plus 2 into 3 into 4 and so on till n into n plus 1 into k plus 2 plus k plus 1 into k plus 2 into k plus 3 be equal to k into k plus 1 into k plus 2 into k plus 3 the whole divided by 4 plus k plus 1 into k plus 2 into k into into k plus 3. And this we get using equation number 1. That is same as k into k plus 1 into k plus 2 into k plus 3 plus 4 into k plus 1 into k plus 2 into k plus 3 the whole divided by 4.  This is same as k plus 2 into k plus 3 this whole multiplied by k into k plus 1 plus 4 k plus 4 the whole divided by 4. Now this is same as k plus 2 into k plus 3 multiplied by k square plus 5 k plus 4 and this whole divided by 4. Now k square plus 5 k plus 4 is same as k plus 1 into k plus 4. Thus this becomes equal to k plus 2 into k plus 3 into k plus 1 into k plus 4 the whole divided by 4. This is same as k plus 1 into k plus 1 plus 1 into k plus 1 plus 2 into k plus 1 plus 3 and this whole divided by 4. This becomes p at k plus 1. Thus p at k plus 1 is true wherever p at k is true. Hence from the principle of mathematical induction the statement p at n is true for all natural numbers hence proved. I hope you understood the question and enjoyed the session. Goodbye.


I actually haven't touched my Nintendo Switch in three weeks. I have put it on charger but that is it. So you know I'm not up to date on what's new on the Switch. I'm not up to date on anything because there's only been one game for me the past three weeks. This game that I'm playing right now is, as of right now, my game of the year. And you know game of the year official video from me will be coming in December. You know at the end of the year. But yeah pretty sure that this one is gonna top all the lists. You know I'm also gonna have a ghost of Tsushima on there and some other games. Now I have probably played Genshin Impact for 100 hours and how I calculated this number if you know what I mean is because I've been playing it every day since the 28th of September and some days I have had gaming sessions up to I think the most extreme one was 12 hours in one day.  So you know every waking hour of my day when I don't have to do anything else basically. So yeah it feels like I've been playing Genshin for over 100 hours. So this is more or less my current and or final verdict of Genshin Impact because I know some of you guys have not tried it yet and I know a lot of you are currently playing it and loving it just as much as I do. But I want to tell you all my experiences with the game so far because I have a lot of experiences with this game right now. I have a lot of things that I could say about the game so I'm gonna go over the most essential points that are fine to be the most interesting. Just a quick look at my progression in the game. I currently have five characters at level 70. I can't ascend them more before I am rank 40. I am currently at adventure rank 38 and my world level is 4. I have been focusing a lot on doing all the quests all the daylies every day and achievement hunting. Some of the better and more time consuming achievements that I've done is completing the entire region of Mondstadt. The entire first region including all the chests and all the sealies. I'm now working my way through Liyue which is the second region. The first region Mondstadt is pretty much like a European theme and the second region is more old Chinese themed. There are coming more regions to the game so I'm also looking forward to seeing more of the world. When it comes to money I have spent $76 in the game. $20 on the battle pass which I found to be really worth it. $5 on the blessing which is also really worth it. And the rest I have spent in the gacha wish system. I didn't get anything good from that so I feel like $25 of this was worth it. On the rest I mean I got a racer but I feel good about supporting the game because like I said in the last Genshin video you don't have to spend money in this game. Well the thing is if you're having so much fun in a game that you find yourself enjoying it for like 100 hours like I have it is just common courtesy I guess to support the developers and support the game a tiny bit so that is what I feel good about having done that. But I have no reason to spend any more money now because I have pretty much all the characters that I want I guess. The only character that I really want to have right now is Mona so that I can go Mona Lisa. Water and electrical Mona Lisa. See what they did there. So when it comes to it being worth it battle pass and blessing is worth it. Now the Switch version of this game. Every day someone is asking me when is the Switch version coming out and to be honest I have no idea why it isn't out but I have a feeling from what I googled that the developers wanted to make sure that the versions that are out right now they are focusing on them being smooth and running properly before focusing on another system. So the game is currently out on PC, Android, iOS which I forgot to include in my last video. iOS is also a thing and PlayStation 4. It has cross save on all platforms except PlayStation 4 which is its own save realm. But everyone can play with everyone. Truly. You can play on PC with someone on PlayStation 4. So that is good. So anyways the Switch version they are working on it but they are just prioritizing the PC, Android, iOS and PS4 versions to run smoothly first. So all my five star items.  On my first role in the entire game I got Kiki. I was lucky. It is actually pronounced Chichi but I've said Kiki for an eternity now. She's a healer so I can see why everyone wants her. I'm really lucky to have her. And I actually also recently got Venti as a 90 pity roll.  And I got Venti. I also have two weapons that are five stars and that is the Lost Prayers to the Sacred Winds which I use on my Lisa. And I just now yesterday got a five star bow that I put on Venti. So all my characters as of right now I have Traveler, Chichi, Venti, Shangling, Lisa, Racer, Barbara, Noel, Fischl, Amber and Kaya. Now I also want to say that when you get further into the game it is important to actually build up two healers because in the Spiral Abyss, which is important, you will need two healers at one point because you're playing on two split parties. Everyone has Barbara because she is included more or less for free right now but I'm lucky to have Chichi as well. So yeah, build two healers that is a pro tip. Now another really pro tip is that don't spend all your XP books on everyone. Focus on one character being strong at first in the game, then maybe two characters being super strong in the game first and then three and then four. And try not to spend XP books on the characters that you're not going to use in battle. I mean like Amber and Kaya. I don't, I never use them because XP books is the way to level up characters in the game and they are later in the game maybe hard to come by. Another tip is that do the dailies every day because they give actually the best payoff in terms of adventure rank experience and it is so important to get your adventure rank up. So dailies every day and also look into weeklies and into the battle past you can see weeklies and seasonal and dailies. Try to do everything there and kind of related to this, always pay attention to and do the quests that you get in your adventure handbook. That is also the best way to rank up in the game. Everything that is in that book is recommended to do as soon as you can. Now obviously I also recommend spending the original resin every day so that it can regenerate up. Now in Genshin Impact there are currently two continents like I said but there has been announced to come out seven, seven continents in total. Now the next continent is actually not far away. I'm so excited for more content to this game and I'm really happy that they are going to be working on this game it seems like for a very long time forward I mean in time to come. So a lot of people ask me is this a multiplayer game or is it a single player game? And I want to answer that it is a really good single player and also fun multiplayer. But I play this mostly single player. It is fun both ways. It's probably what people wanted to hear. Another thing I find really convenient with Genshin is that it has mobile cross save. Like if I'm not buying my computer I can take up my phone and do my dailys. It is so convenient. This kind of makes me wonder if it will be cross save to the Nintendo Switch when the Switch version is out. I have no idea. I have a bad feeling that it won't be just like with PlayStation 4 it will be its separate realm of save files. I don't think I want to start Genshin all over again when it comes to the Switch so I am gonna just continue most likely to PC game Genshin even when the Switch version is out. So I mean it's kind of weird that I haven't touched another game for all this time. That rarely happens. It is kind of unique. But Genshin is like filling my every need when it comes to video games right now. It's truly fulfilling. It gives me everything that I want when I sit down with a video game. I also still stand by everything that I said in my first video that I made on Genshin just a few weeks ago. I think it is a 10 out of 10 game like quality wise. It's a 10 out of 10 game superb gameplay. Story telling and voice acting and character diversity. So many characters and the potential to drop even more characters. That is genius. The sense of freedom and the sense of progression constantly. Everywhere you look in the open world you have chests, you have sealies, you have puzzles, you have enemies, you have all these things. So it's so much fun to grind for materials every day. There's just plenty of things to do in the game and I don't run out of things to do in the game. And the thing is when you play these characters you sort of get a special relationship to each and every one of them that you play a lot. Like take me for example. I didn't like Shangling to begin with but after playing her for such a long time and I love her elemental burst. Yeah I've started to really enjoy and like my characters.  You really get to know them, you know. So yeah I haven't played anything else. I mean I tried Among Us with my discord people a tiny bit. It was fun. I was not the imposter. Now I got some questions to include from Stephanie on the discord. That is what is your favorite build and stats? I mostly in the beginning of the game anyway went for attack percentage. That is the best one. Now recently I am focusing on that of course but also on crit rate percentage and crit damage percentage. So those are my favorite stats to look for when I am building my characters. Some exceptions though is Barbara. She builds off of HP. It makes her heal better. What are your favorite farming routes? I can show you on the map. I farm for the ascension materials for Chichi at this location. I farm for slimes at this location which is really good and on this location. Everyone needs slimes in this game for their ascension. Like the whole bunch of them now are needing slimes. Favorite weapon in the game, I guess favorite weapon type is actually Catalyst. This brings me to my next question as well. Who is your favorite character? That is Lisa. Lisa is an electrical mage which uses Catalyst. Which is like a book or an orb sort of thing. The reason why I just find myself to love her combat and playstyle the most is because she can fight in a long range. More so than the bow and arrow users I feel like.  So I don't have to move around so much. I can stand in one place and I can spam the button and she reaches everyone. I find it so good. So Catalysts are my favorite weapon type. Now this is becoming a really long video but I'm gonna end the video by telling you about some collabs that I have been joining lately. I have made a collab video with James Lugo here on YouTube and we talked about the Switch Online Service. In his video over at his channel there is an exclusive video on his channel linked down below. Another collab that I have done is with 8-bit Eric again. We haven't collabed in a long while but finally we did. I was on his channel talking about my most anticipated upcoming PlayStation 5 games. That is also a really cool video. I gave it my all. So I really would like you to check out that video as well. Link below. Other than that I have been on my cousin's channel a lot. A bunch. There's so many videos on there with me in it and I am talking about games I recommend to him and I'm also in the video where he talks about his top 10 computer games. So a bunch of things in that channel as well. So go over there and check him out as well. Subscribe to all of these. And I think that is pretty much everything that I wanted to cover today. I just wanted to tell you guys that I haven't played anything lately. Except Genshin. So I was like Jesus Christ I haven't uploaded in like 10-12 days on YouTube but I haven't played anything either. So what do I update my YouTube channel with? The game that I have been playing obviously. It is what came naturally to me. I wanted to talk more about Genshin because it's I love it. Love it. Like truly love it. It's like if Atelier series and Tales of series and Zelda made a baby with a sprinkle of World of Warcraft vibes on top of that. That is Genshin Impact for you. I don't know if you guys know this but actually hitting a like on a video helps the YouTube out. I'm sure you knew that. Anyways I'm gonna end it here so you know. Thank you so much for watching and I will see you later.


Oh, it's very cozy with a very cozy group of people Cool. So today I'm going to talk about release best practices. So these kind of like hard-earned experience I've got over the years Like number of times when I have to wake up in the middle of the night trying to troubleshoot things and from there Then you learn how not to do things It will help you guys, you know future career or actually right now If you're handling some internship or any other kind of deployment Right. So a little bit about me. It's already Introduced so I basically a software engineer and data engineer at Facebook for Singapore for a couple of years and then Earlier this year and moved to a startup world again So I graduated from computer science and us back in 2015 early 2016 Sweet, all right. So, oh a little bit about business AI. I Compulsory to do this. So we're doing ML deployment platform for enterprises and we hiring so Her bird here is also our intern last summer So if any of you want to know what house work at basic AI just asking you give better accounts than me All right, so compulsory memes one does not simply release code on a Friday So why do we why do we not do that? All right, because obviously you want Saturday and Sunday to yourself You don't want to wake up and like try to troubleshoot. Oh, what's happening with the database? What's happening with real latest release of the code? So It's a it's a meme, but it's real. So keep this in mind If there's only one thing that you take away from this talk this So what is a release it's basically you apply changes to your production environment All right, production environment is in code change database schema change whatever that is So in short, it'll be the first time your user actually use something that you have been cooking Right, so this can have a very small show of hands who have like deployed something So as in there will be real users who are not your friends who are not yourself But like complete strangers There's a few a few people I guess right cool.  So if you break the application Obviously, they're going to be down time and you disappoint a lot of people your friend yourself and your users So let's try not to do that Someone has to fix it when you break it, right? But you yourself your team your boss wherever that is and at any time because it's not good to have any Down time at all. So 3 p.m. Or 3 a.m. Then you have to wake up to fix it So going to now what are the very rule of thumb of releases? So why do I start with this because the actual act of releasing something? It's very simple most of the time just clicking buttons. That's it Click a deploy button and then that it will change into make the change into production area and then that's it So in in this very small particular case There's just a few things you need to worry about first of all don't release on a Friday I hate repeating myself, but this true or for all practical purposes Don't release it anytime when you are about to go and leave for anything. You don't want to touch work at all Then don't do it Second of all plan to be around for at least one hour. So if anything Clucks up after the release then you were there to fix it because you have the most context, right? And third of all let people know let your team know. Hey, I'm doing this if not then Too bad. You're the only one on the hook Cool. So with that out of the way, so the keys to safe release Aside from that just very opportunistic convection is all the planning that comes before that So it has a lot more to do with how you do the development yourself, right? How do you? Think of backwards and forwards compatibility Because breakage happens when either of them don't work So there are a few types of change when it comes to production release Either you do a code change often time code changes Stateless as in you can it's just a binary you switch one version for another and it's just still Not too much of a problem the second one more complicated is when there's data related change when there is like data Schema change or some if you are like a schema schema less Database then there'll be data format change if you change the log format To from one column name to another or one field name to another you can crash someone else's dashboards and like monitoring will trip you up And third time is config change you change your web server You change your load balancer config you change a C name and then oh all of a sudden you can access the site anymore so those are three main types of change and Within the context of this talk I focus more on the back end and web releases because mobile Releases are very different Anyone want to take a wild guess what mobile different it's different from web and back end Yes refuse so you want to release the app store. There will be an additional step for you to release it It's not like you just click a button and then it goes out So to keep the focus of this talk, let's think about back end web only So those are the more manageable ones and people will tends to have developed good practices around it So the first type code changes so Before you do anything about code changes try to think of Continuous integration and continuous delivery. So this thing is actually just kind of a pipeline And you get a lot out of it if you don't have any other type tooling yet. This is the first thing you should do so There are a lot of things out there that are already Off the shelf so you can use their Jenkins Travis so-called CI team CD Basically, you visit any of the more proper GitHub repository then you will see a batch of any of those things Have a check if it's not a check. There's a red or something then probably don't use that So the idea around this continuous integration and delivery is just From your code changes you make one liner to line a change or whatever And then you before you try to merge it into your master branch. It runs through a whole bunch of automated testing Automated like deployment even so these all of these infrastructure is already to make sure that your changes before being merged in is already Like somehow is already vetted. So your merge is safe So and I will not talk too much more about continuous integration and delivery because there are a lot more informative blog post about it that you can search online Let's just zoom past this point They'll be Q&A towards the end and second type second trick they can do for releases It's why I call inserts to colors deployment because people call it various names blue green red black whatever The point is there are two version of it So when you make this one version with the new changes and there's the old version So all you have to do is just you bring up the new version with all these new things Nice things that you've built in the past couple of weeks And then you just make changes to the load balancing Layer so that you can point all these traffic from the old version to the new version that's basically the idea behind it and there there can be multiple levels of Configuration there are some load balancing tools that you can direct like percentages of your traffic towards a new version And there are others like you can just like flip or switch or something and it will revert everything to the new version So they do to expand on this idea. You can see that you can move traffic from 0.1 to 0.5 to 1 to 2 percent all this thing So one of the story I had when I was working at Facebook was that That for a site that is for like billions of people literally You would have thought that they have very stringent process of like releasing whatsoever But the the thing is you you'll be amazed that all these tools Are built to automate the majority part of it So if you make some changes you merge it in and literally hours later It'll reach the millions of people out there. It's because of this traffic moving steps so they release it in in so-called circles on 0.1 percent the traffic first if the Monitoring tools don't trip up then you increase it gradually until like hundred percent the traffic is using the new version of it and Now this is purely kind of a technical thing right so like controlling traffic diverting traffic What not what not it's typically a job at a debuff engineer or a software engineer, but to expand on this What if you can control the release that is completely different from the? From like the business need of releasing a feature completely different from releasing of the code So the idea is that you ship the new version of the code, but you can dynamically Tuckling your feature to be on the off So you can target certain couple of certain groups Let's say if you release a new version you want to target only the internal user first all only employees will be able to see the change Then you you would release to that group of people first everything goes well Then you expand it to the rest of your company or the rest of organization or target certain customers You want to test out so basically the idea is that you can be couple feature release from code release So if you talk to non-technical people they tend to get very excited about this So that's one thing to keep in mind as well and do on there There are a few off-the-shell version that can a services that can provide you this But actually building one yourself is quite interesting and it's not difficult at all So you can kind of like research on this is very famous person Martin Fowler You wrote like an entire piece about feature of toggling so that's something you can look up on as well So the third one is API versioning So let's say your code changes or whatnot They're all internal to your application if you change your back end and the only consumer is your front-end and probably You can even if you trip up something It's still easy to just revert it because you control of both right now It comes much trickier trickier when you have an API and because when you have an API then the consumer set is not only Yourself anymore. There are other people who depends on particular version of the API to work So how do you try to got against this? So you try to follow semantics versioning So what semantics versioning try to do is just that if you have a way of naming your Your your versions right then people kind of know what to expect out of it So let's say if it's one point zero then it kind of means that hey I'm ready generally available if it's two point zero that it means. Oh, I'm still ready still generally available But there are non backwards compatible change as compared my version one So that actually is very helpful to me Let's say if you release version one and then you're not happy with the design or whatnot Then you can build up your version two while at the same time maintain V1 to work And then after that you press release or whatsoever to say that hey now have V2, which is so much better So why don't you guys move to there? And basically just don't break the existing V1 API and create a new version instead so let's say V1 actually there are a lot of times when V1 is due for deprecation and this Deprecation process take months or even years if you're looking to Facebook graph API for example the first version of it I believe from the moment it was released until it was fully deprecated it took like five years and The larger part of that of those five years is spent in deprecation mode So if you trigger any of the call to those APIs then it actually returns you some sort of warnings That you shouldn't do that and people and Facebook send you an email saying that you shouldn't trigger this endpoint anymore and The very important part if you want to do API versioning is that you have to have some sort of Tracking some sort of metrics to say that hey how many people are still using my old API version If not, then you don't know when it's a safe time You kind of like cut off and okay now I can just delete all those if you want API anymore So the third point is very important for this Right. So after all the code changes, they're more of less like binary you can just switch between version It was if it's too much of a trouble. We break something. It's like, okay. Just revert no big deal Right, but what if it's a database related change? So database related is much more much for trickier because first of all they the for database rolling back is actually much much harder and If you trip up something with a database, you might lead to permanent data loss so there is this incident about GitLab happened like about two three years ago and It was quite a hooha at the time because they lost data for like six hours And somehow eventually they got they managed to recover from it But imagine if you do something and then you don't have proper backup then that six hours Worth of data will be gone forever.  We can be able to recover from it. So For database changes, there are a few things that we can try to Look into it All right. So First of all, make sure you have backups, right? So if you most of the time you would use a cloud providers database service so they already have Various built-in kind of backups mechanism is either like every hour every day or like some trigger A lot of APIs you can trigger it and then it will do a backup for you So you don't have to worry too much about the logistics of packing up things and generally there tends to be pretty Pretty good with recovering as well You don't have to worry too much about the integrity of the database backup that that like GCP or ADLS created for you then But still it's a good idea to like every now and then test your backups and make sure that hey this thing works If not, you're just backing up jumps in like the moment you need it is like, oh shit doesn't work and then 13 After you have all the backup all the backups are tested already then you still have to worry about Backwards and forwards compatibility Right So what it has to do with the database is that let's imagine you change a Column name, how do you make this change safely because there are various part where it can fail, right? You can start writing to the new column although your schema hasn't changed You can still read from the old column while your schema has already dropped strange Like how do you enter in what's the interplay between the code and the database schema? So one one thing the code is stateless whether the database itself is stateful So this thing is is a well covered topic So strike engineering actually have a very good Tutorial kind of about how you can how you can do this and I was just right out the steps here because they are very common And it's not that difficult to follow at all. First of all try to double right So if you create new you want to rename a column You create the new column and then you write it to both the old and the new version of that column So that you still maintain the data integrity parallel in parallel after that Then then you can run data migration can copy whatever of the old column over to the new column So you make sure that from there on all of your new Your new column have the full data set from the history as well as Present and as well as your future because it's already writing to the new column Then after that the third thing you can remove the read part of your old column So now because you already have it in the new column You don't need to read from the old anymore And eventually you're going to remove the right from the old column as well after all these four steps are done Then your interaction between your code and the old column is already disappeared Then you can safely drop that column or even table or whatsoever so it's kind of like a five-step thing and It's if you visit the link that I have here is actually a lot more interactive people Spend time did animations and whatnot, which is better than what I'm trying to do here So I recommend highly read that blog post from Stripe Engineering Right, so the third type of change that usually has to do with deployment is config changes So config change like web server change load balancer or whatever else that doesn't get captured in the database or captured in your code so a Very famous incident just a few months earlier in March Facebook had about 14 hours of downtime Partial downtime like images or whatnot couldn't load at all And the reason happening was there was some config changes that made it to the entire fleet of Facebook servers And then it just stopped working and if I'm not wrong it was it happened by some intern so so if you if you keep that in mind and you would not Boaster the stereotypes of of intern season anymore. So This is keep keep that in mind, right? So the first thing about config change don't don't just once one off and release it to the entire fleet of your server gradual rollout by gradual rollout I mean choose a specific group of servers or targets you want to make changes to Make changes there first and then observe how they behave after that if all goes well Then you can release it to a larger group kind of like similar to how the code changes. I suggested earlier Another thing is you can consider Some key value store there are various one that are pretty good by console zookeeper so those key value store basically can host your configuration as well and they tends to have good either back up or edits Mechanism built in so let's say if you change something and that doesn't work You can revert to the O version pretty easily And then the 13 is version your config so let's say if you add another row when you change another config values Just create a different version for it all together and name it like V1 and V2 so later on if V2 doesn't work out well just revert to V1 kind of like make it instead of a config change convert that into a code change So that's the idea behind like infrastructure as code as well before that everything is kind of ephemeral and Like states are everywhere. There's no good way to track it now People say that hey you should track all your configuration or your if you structure in version control as well So the config changes to deal trick about dealing with it is actually try to convert them into code changes And that would be better for everyone But of course don't commit your secrets right database password or whatnot. Absolutely, you know, but other things, okay Cool, so I try to wrap it up in very short amount of time. So now it's Q&A If you have any questions about like releases, what are some of the things that you have been wondering about in deployment Yep So Usually if you have a mechanism to do this traffic moving then there's some mechanism. There's some manual Switch for you to turn the version immediately back if you say there's like 0.5 percent is breaking things Right, then usually some dev-off sky will press the button and then you'll revert to entirely the old version So it depends on the company or the practices as well But most of the time what I see is that they will revert the entire thing back to zero kind of yeah Depends on your tools, but that's what you should aim for Hmm good question so First of all, well, I'm not the infrastructure kind of guy so like You know like the software engineer usually Don't like directly interact with the servers, right? Usually there will be a dev-off team or infrastructure team or production engineer teams that Focus on maintaining these these server and the basics infrastructure like networks whatsoever So I am I might not be best position to do that For my little experience dealing with with that area though The first thing you check is usually whether the note is up like whether it's Physically you can like connect to it. You can check if like it's then you can reach it is it reachable via network You can use SSH to it. What are the? Ways that you can communicate with that server Then after that But but these these kind of in the old days where a server actually matters a lot a lot nowadays Servers is kind of treated as fmural. You just migrate the workload somewhere else But the first thing is just check for whether you can connect to the thing at all Second of all is look into your locks The locks means either is the centralized logging or in some times you actually have to After you connected to the the the server then you look into their slash bar Slash lock and then certain services that you are interested in and you kind of like dig up from there and From from there onwards, then it's very Specific to your stack your application. So From there on this varies your mileage is not guaranteed by any Sequences or anything There's actually a pretty good book from Google site reliably reliability engineering is is just a reliability engineering Something something it's from from the guys who maintain server farms and whatnot Google And maintain the basic infrastructure as I as I mentioned and a lot of good practices are actually in there So if you are more interested in this area, I recommend go read that book instead a be testing So this actually has a lot more to do with this because AB testing essentially you want to maintain two version of your application at the same time, right and A lot of the time you want to control the group that receives one type of treatment versus the other So like some sort of feature toggling some sort of feature targeting is absolutely crucial But something that's very specific to a be testing though is you have to make sure you measure Your your success rate After you divide the group then you have to have logging all sort of metrics data and you pump it into your data warehouse and Perform analysis to say that a group A is better group B Or certain things like that So it's called closely related to it But it has a lot more intricacy because you have to build your data infrastructure next to it So that I believe there are a lot of other literature that has to do with a be testing So I might not be the best guy to answer this Yeah, so spin up a different database try to recover into that And like just run sequel stuff on it or if you're best yet if you have some Automated database testing like the one you built for us And that'll be cool So, yeah Again, I'm not the database Administrator so there are there are other best practices Specific to like testing your back up and whatnot that I might not know about cool All right, thanks guys


The market starts to go dumbfounded, right? It starts to go numb to bad news. Again, we went bad news numb during the pandemic, right? Well, if you know it was 2020, March of 2020, the worst month, like in 20 years, what happened next month, right? April 2020 was like the best month in like 20 years. Is it possible we start reclaiming tomorrow's channel and start really getting aggressive? I hope so, right? I hope so, because again, the longer the bulls can keep on taking that punch to the guy, taking the kidney shot, taking the upper hand, taking the elbow to the throat and all that good stuff, eventually the sellers will get tired. If the bulls can start putting in a new channel, 2.99 and a half, 300, well yeah, there's a shot that we start expanding, right? We go to 301, which is the high from March the 9th and then ultimately if the bulls continue to go, then we're talking about the highs here, right? The highs here of 304 from March the 6th. So we're set up here.


Well today I am back and I am not making any promises on doing a video schedule at the moment because life has changed dramatically for me this last month and I am just finding it so hard to get back into a schedule of things and to keep doing as much bookish stuff as I used to do. I know this is a book haul video but very quickly to begin with, as for how my life has been going I'm actually in a really good place right now. I have had the same job for like the last five years and although I have enjoyed that job I think that in the last few years it has really brought me down and I haven't enjoyed it no near as much and my quality of life hasn't been as great so I've actually got a new job now working in a bookstore and I'm really enjoying that and it is also part of the reason why my book hauls are going to be so big now because I get a lot of good book recommendations and I get a few free books and they're just something that I can't resist buying. And other things in my life have kind of been on and off. I had my heart broken for the first time which was a joy. I am now a mother to three orphan baby geese which is also a joy because they like to chirp all night long and I also have family over at the moment from England so I've been spending time with them and it has just been really hard to read at the moment and to just get back into everything bookish but I am going to try my best because I really do love you guys and appreciate the book community and just something about being surrounded by books just makes me feel so much better. So despite some bad things happening to me I'm actually in a very good place right now and I'm actually surprisingly pretty happy at the moment. Everything's kind of going really well for me and I just think that I have learned a lot about myself in these last few weeks and that's going to help me to grow into the person that I hope I can be.  So I mentioned that I do have family over from England and it is my lovely Nana and Pop and my Nana went and bought me this book from a second hand bookstore. It is called Norman Lindsay's Cats introduced by Douglas Stewart. I haven't actually read it. I have flipped through this and the artwork in this is actually so so adorable because this fuzz buzz big game hunter is trying to chase his chicken. It gets onto its back and then the chicken just totally runs off and kicks the cat into the dust and it's just like illustrations all through it like this and it is super cute and I really love it. Next up is a book that I read really quickly because it is a small poetry book and I tend to just devour these all-in-one sittings and I really enjoy them because they're quick and easy and I just it was so much emotion that I just enjoy reading them. So you're a fan of Milk and Honey or the Princess Haste herself when this one you've probably already heard of World's of You by Bo Tappelin but I definitely recommend you pick it up. This one is mostly about like love and heartbreak which I probably shouldn't have read at this point in time but I did get through it and I didn't cry so yay.  But let's appreciate this absolutely selling 25th anniversary edition of this book and I'm so excited to actually read it like it has the fold out like edges so I only need to you know fold the pages because I'm a monster. This is next one I got from the publishers and that is The Boat Runner by Devin Murphy. I have heard amazing things about this and I'm pretty excited to get around to it. So this is a historical fiction novel and from what I gather about it it follows the story of two young boys they are fishermen in their village and when things start to happen during the war they get sent into one of Hitler's camps and to be trained up for the war and because these boys have experience with boats they get put into the navy and pretty much they have the moral dilemma of having to fight in this war knowing it is wrong versus doing the right thing. So I think it'd be quite an interesting read. I'm a big fan of historical fiction so I should hopefully get around to that soon. Unearthed by Amy Coffin and Megan Spooner. I don't even know anything about this book besides the fact that I really want to read it. I have loved books by both of these authors before so I'm pretty sure I'm going to enjoy this one. I did not know what to think about this book when I first heard about it but I'm actually really starting to grow curious about it and I would love to hear your opinions if you have read this book because I don't know how it's going to go but I do like the concept of it and that is The Afterlife of Holly Chase by Cynthia Hand. So you have our main character Holly who on Christmas Eve five years ago was showed how selfish and spoiled she'd become. The ghost tried to convince her to change her ways and she did not so she died and when she died she got put into company project to Scrooge and became the latest ghost for Christmas past. So pretty much every year that she has worked on she's been miserable and grouchy and hated her job but this year that the book is written about things will change. This next one is a book that I could not refuse buying. It is probably one of the greatest book purchases I have ever made because I am a lover of food and I am also a lover of books and so when I saw the Little Library Cook book a hundred recipes from your favorite stories by Kate Young I could not resist. And let me tell you that this is actually a stunning book first of all like the pages that are just absolutely gorgeous and the recipes are also really a big range of food as well and I'm going to be using so much of the Christmas stuff like for the first one here we've got Turkish delight from the Lion the Witch and the Wardrobe then you have Buckwheat's by Little Women by Louisa May Alcott Christmas Dinner which is a Christmas Carol by Charles Dickens and it just continues on and it had got so many in here and so many good books as well so I feel like I'm just going to spend so much time enjoying food and books at the same time. As you guys probably know I've been in a reading salon for a very long time and I've probably mentioned just a couple of times that I am a trash for romance books and so I've started reading The Closer You Come by Gina Showalter and this book I was not prepared for I started reading it and I thought I was going to despise it because it was so cliched and then all of a sudden these like steamy scenes start happening and this is like the steamiest book that I have read so like I'm getting like very like scared to continue reading this because like nothing big has even happened yet but like some of the sentences that I read I'm just kind of like this isn't a cover I can read in public I was on my lunch break and I sat at the table and I started reading this book and I'm reading it like this and I can just see this old couple seeing to the left of me giving me some weird glances and that's when I remembered that this half-naked man is on the cover of my book so I proceeded to pack up my things and go and sit somewhere else because I was that embarrassed but I'm actually kind of intrigued by how the story is going to go like there are parts of it at the moment where I'm just like communicate and it wouldn't have any problems. I'm sure you guys will see a review when I do finish this though. This next one is actually super super cute so I went to the Dimmicks book club last night and that's where I bought a bunch of my books that is also where I'm working. I work at Dimmicks now. Yay! And for the book club we did a Secret Santa so everyone bought a book under $20, wrapped it up, put it into this giant sack of book filled goodies and then everyone just picked one out and the book that I got was Dorothy Must Die by Danielle Page and my Secret Santa gave me this really cute letter and I just really really felt at home at that book club so I'm very excited that I got a book that I haven't actually owned already yet. Yay! So this is like the horror version of The Wizard of Oz. So in this book you have Amy Gum who has been given one order. She's been recruited by the revolutionary order of the wicked and she has a mission to remove the tin wood man's heart, steal the scarecrow's brain, take the lion's courage and then Dorothy Must Die. This is another arc that I've got. It's called You, Me and Everything by Catherine Isaac. It says when you're surrounded by love you have nothing to fear. So from what I understand this is a book about family and love. You, me and everything is a heartfelt and unforgettable story about the lengths we are prepared to go to for those that we love. I won this book a book club and it is called Beyond a Dark and Sure by Jessica Leake. I picked it up purely for the cover and from what I'm gathering this book is a romantic historical fantasy standalone and it is also the debut novel. It sounds like it's going to be interesting but at the same time there is a whole lot of information on the back here and I'm not too sure how the story is going to go for it being a standalone. It does sound like it's going to be pretty hectic. So you have Chiara who is a princess and she can protect her people by manipulating the minds of her enemies but there is a dark and still closing in and she starts to like vision this crow and then she ends up meeting Leif who is a Northman leader and he sees these visions too. So the two of them have to then band together to save the world and it just sounds like a lot is going to happen but I don't really know how the story is going to go. We have Stags or S-T-A-G-S. I'm not too sure about this one but it is by Emma Bennett and nine students, three blood sports and one deadly weekend. Interesting. We also have the 2017 YA Fanfest book by Ellen Unwin. So this just has different snippets from different authors and books that were coming out or are coming out. So you've got one from Emma Bennett, Holly Black, Libba Bray, Wei Chim, Gabby Dunn, Allison Raskin, Sally Gardner, Vicki Grant, Jay Kristoff, A-Lockhart, Ellie Marnie, Penny Rosson, Claire Schohan and Lily Wilkerson and I apologize for those incorrect names that I no doubt said. We have the extremely inconvenient Adventures of Bronte Metalstone by Jacqueline Moriady. Now I'm not going to read the entire blurb of this but I'll just read this first like sentence or two. I was 10 years old when my parents were killed by pirates. This did not bother me as much as you think it might. I hardly knew my parents. That sentence straight away has me so intrigued but unfortunately this is only suitable for readers age 10 to 14 so I can't read it. That's a joke of course going to devour it. This next one is the book club book for the next two months and that is right where you left me by Kala Devlin and I'm actually pretty intrigued by this book. So you have our main character who's a young girl and her dad works as a reporter and he pretty much will go and fly into the eye of the storm to try and get the best news possible for his business. And so in this case he leaves to go to the Ukraine and the FBI come knocking on their door one day and they have to fight off these images in their head because something bad has happened. I don't think he's dead but their daughter is talking about saying that she will do anything to get her dad back no matter what promises she has to break or what laws she has to break. So I'm pretty interested how this one turns out. I'm not too sure about it so if you guys have read it please let me know and hopefully it'll be good. I have two books left and these are like two gifts that I got myself because I have no self-control. The first one is The Beauty and the Beast. This is illustrated by Mina Lima and this is so stunning. I have the Peter Pan version of this book and I love it because it's kind of interactive like you get pop outs and fold outs and like posters that you can take out and stuff and I cannot wait to open this and actually take the time to go through it and just absorb all the beauty of this book. And as for the last book that I bought it is quite heavy, quite big and quite beautiful and it is The Art of Harry Potter. I should not have bought this honestly. I really shouldn't have like I don't have the money to justify paying for this book. I don't even have the shelf space to add this on here but how could I say no? It is actually stunning. I haven't got it open but like if you guys look it's got some of the artwork on the back there and it is just it's amazing and I cannot wait once again to take my time going through this book. So there you guys have all the books that I have got most likely in like the last like two weeks. I know it's a huge pile and I have actually read a few so I feel like I deserve to have that many in this book haul. That's pretty much all that I've got for you guys today.  I am also doing the social media for three of the Demik stores. I'm gonna leave you links to their Instagram below if you guys want to check them out and like all their photos and stuff because it really reflects well on me. I hope that you guys have all been doing really well and you're all getting excited. It is December which is Christmas month and my birthday month which I'm super excited for and yeah that's pretty much all I've got for this video so I'm gonna stop rambling now and just say bye. Have a lovely bookish day and I shall see you guys soon. Bye. Hey guys it's Tilly and today I'm here to show you guys my new bath product range so I have just started out on my website at tillyandherbooks.com. I am very excited to show you guys


Good evening. I'm calling to order the meeting of the Allenton Select Board from Monday, November 29, 2021. This is Select Board Chair Steve DeCorsi. Permit me to confirm that all members and persons anticipated on the agenda are present and can hear me. Members, when I call your name, please respond in the affirmative. Diane Mahan. Yes, thank you. John Hurd. Yes. Len Diggins. Yes. Eric Helmuth. Yes. And Board Administrator Ashley Maher is participating remotely. Tonight's meeting of the Allenton Select Board is being conducted remotely, consistent with an act signed into law on June 16, 2021, that extends certain COVID-19 measures adopted during the state of emergency. The act includes an extension until April 1, 2022 of the remote meeting provisions of Governor Baker's March 12, 2020 executive order, suspending certain provisions of the open meeting law. And as order, which is referenced with the agenda materials on the town's website for this meeting allows public bodies to meet entirely remotely so long as reasonable public access is afforded so that the public can fall along with the deliberations of the meeting. Before we begin, let me offer a few notes. First, this meeting is being conducted via Zoom, is being recorded, and is also being simultaneously broadcast on ACMI. Persons wishing to join the meeting by Zoom may find information on how to do so on the town's website. All participants have advised that people may be listening who do not provide comment, and those persons are not required to identify themselves for the broadcast. Both Zoom participants and persons watching on ACMI can follow the posted agenda materials, also found on the town's website, while using the Novus agenda platform. Finally, each vote tonight will be taken by roll call. I will now turn to item two on our limited agenda this evening, which is the final vote for the 21 precinct map. Joining us again this evening is Atom clerk at Julie Brazil. Good evening, Mr. Brazil. Good evening everyone. So this is luckily going to be very fast and very simple. You've been provided with the map, which was produced by the Secretary of State's office, and the table of census blocks that was provided by the Secretary of State's office that does show all of the census blocks in Arlington and which precinct they are now assigned to. And the final piece you received a draft on Friday, I mean on Wednesday of the text descriptions of the precinct boundaries over the holiday. Adam Krawski revised that draft to fill in the gaps that the state was unable to sort of clarify. And then the state, I provided that draft to the state this morning. I also provided a draft proof reddit and agreed that Adam Krawski had used reasonable descriptions for things that are not roads and streets and slightly difficult to describe in writing. And I can now share with you that final document in draft form it has a grand total of four typos. If you are comfortable with those. And you can vote on it and they'll all be done and sent off to the state in the morning. Any questions on that part so far and then I'll show you the document. No, that's that that's fine. Do you want to start with the map to I don't know if we can start with the map and then go to the narrative just. Oh, I'm happy to. And just briefly, but I mean it's a little bit. And just while we're doing that. And you and I discuss this what there's no change in the narrative changes is nothing changed from what we voted last week it's just some minor corrections that the state had suggested on some Yes, yes, what you voted last week was the map. And so then we just a question of producing the actual descriptions. That go with. Is that the map. Yep. All right. Let me share the map. So while you're doing that I'm getting word that we may be having some audio problems with a CMI this evening so it's we'll try to work through those. All right. So this is the map. The state prepared it based on the files that Adam Korsky sent. And they generated it in the formats that they want, including the table of names and populations and the variances. So this is just it should be exactly the same. I was able to double check specific things and I double checked to make sure that we agreed on all of the population counts. For every precinct so that's the map. And then I can share the next descriptions. This is just a requirement. In order to, you know, in order to just describe as if you were standing literally on a corner, the street corner and walking the boundary of the precincts. The only changes. So what the document that was posted on Wednesday had some gaps in it. The document has cleaned all of that up and been reviewed by the state. In precinct nine. I propose that we amend the document so that we spell cemetery correctly centerline correctly. And the state. The state said suggested that we describe proceeding northerly along situate street. So it's just a little farther along proceeding along the shoreline of spy pond. And it's not to it's just along the shoreline adjacent to Pleasant Street. So it's just a slight clarification in the description. If it makes anyone feel any better, these four changes are purely grammatical and wouldn't have harmed the underlying accuracy of the of the description it would be possible to tell. What we meant. In terms of the legal description. So we have the descriptions for all 21. And I'm happy to answer any questions. People have at this point. In this Brazil one other question before I turn it to to board members do you have a copy of the proposed vote that you can share with the board as well. If not, I can read it. I can. But I mean it's pretty much one sentence. If you'd like, if you'd like to read it. Sure. Yeah, it says so what what's going to be before us is we have the map we have the narrative in the proposed vote that was sent over to us by by Ms. Brazil but also I think suggested by the secretary state is it says we the undersigned here by certify that at a meeting held on November 29 2021. The select board voted to accept as presented by the town clerk, the 2020 re precincting plan for the town of Arlington, and if voted it will have all five of our signatures. So with that I will now turn it to the board now start with Mr. Diggins. Thank you Mr chair. So, Mr. So cemetery, you're going to correct the spelling of that. From what's wide. It was missing an E. Because I wasn't sure I thought you, I thought what you had there was the correct that is the correction right. Yes. Okay, good because being later on we had to to there, and you hadn't. You said we're not going to have that I was like. We'll remove will strike the two. I got you. Yeah, okay so now that we're in agreement on cemetery. I can put this arrest in my mind. Thank you. Okay, Mr helmet. Thank you. I'd like to move acceptance with the boat language that Mr. Of course he read. And I want to add my thanks to the town clerk for her exceptional care through this time process up to the end here. And the whole working group that she put together are very hard working and very capable staff. And since he worked through the holiday, I want to give a special shout out to our director Adam Kuroski, who does a lot of unseen hero work for us in the town and this is no exception. We are very fortunate to have his skills and his integrity through this process and I just had to say something since we're looking at the product of his painstaking work. Thank you. Thank you. Mr. I definitely would like to second that and I just want to make sure that a motion is to accept the town clerk's 2020 re precincting plan for the town of Wellington and included in that are the actual descriptions of all precincts. And I want to also second Mr helmets on remarks regarding Adam Kuroski unseen unsung all the uns ever in terms of what he's contributed not only to this item but other things here in the town of Wellington so it's a great employee. It can never be replaced so thank you Mr chair. Thank you Mrs mahan on Mr heard. I am happy to support the motion. And thank you to our wonderful town clerk for joining us again into everyone that's worked on this and I will third Mr helmets remarks regarding our, our wonderful town staff. Thank you. Thank you Mr heard yeah now for that I also want to thank Mr Brazil there's a couple questions I had at the end of the last meeting she and I had follow up conversations and she actually showed me a few things and there's nothing that I would change so I wanted to just close the loop on that and I just wanted to make sure for the work that you did and Mr Kuroski as I said he's a hero of our of our last time meeting but also over the holidays doing a lot of work to make sure that this could be done for this evening so we really appreciate the work that he did and and the work that the other members of the re precincting working group have done over these last several months. So on a motion by Mr helmet, seconded by Mrs mahan attorney Heim. Yes. Yes, Mr helmet. Yes, Mrs mahan. Yes, Mr de Corsi. Yes, it's unanimous vote. Thank you Mr Brazil. You're very welcome. Okay, so it's not very often before 730 that we move to new business but we're going to go right into new business and then we will have an executive session after that so I will start with attorney Heim. None of this. Thank you. Mr chapter line. Thank you Mr chairman. One piece of new business tonight, continued compliments to our health and human services team, the Arlington public schools, and really the town population as a whole. The town continues to really dramatically lead in the rate of children ages five to 11 that have been vaccinated as compared to every other city in town in the Commonwealth. And, but at almost a 90% clip. And it's truly a test to the hard work. And I think it's a great contribution of Christine Bargerona and her team superintendent. Dr Liz home and her team, and having residents and parents that follow the science and are making the choice to have their children vaccinated and great support and help from the Arlington fire department and the Arlington police department and staff from the school to quickly put together these clinics where all reports suggest the children that are coming to get vaccinated feel as safe and comfortable as you can feel when you're getting a needle in your arm. So, just want to get pay high compliments to the team of people that are working hard to make these vaccinations available and congratulations on a job well done. Thank you Mr chapter line. Mr helmets. Thank you. And I'm glad the time manager brought that out. I spend a fair amount of time on public service Twitter and social media and Arlington is is actually the talk of the state right now. And I think that these are envious and all of our vaccination rates in general, and of kids and as Mr Chaplin said that really speaks to just how on top of this it isn't. It's so important because it heads off to the parents who trust the science. This will make everyone safer, the kids, everyone, the grandparents of the kids interact with and it's just a real credit to to our community that we're able to come together so and to do that and to jump on this so so thank you for that and please pass our thanks on to your team for their continued hard work as we head into two to year three of this pandemic pretty soon. You know, it was tired and they worked really hard as all our town employees were very grateful. I just wanted to highlight a couple of things that I've been saving. I think it's really important for the community to know that the town staff that works really hard to secure grants to supplement our revenues that we get from from property taxes and other sources to make our program stronger and to make our dollars go farther and about about a month ago. The town announced $100,000 was awarded from the Department of Energy's green communities program to install high efficiency LED lighting fixtures that person bracket elementary schools installation of the safety building. That's great because great revenue news but it's also really great sustainability news for the town and I appreciate the town manager and his teams continued walking the walk in that area. And also in the area of open spaces and resources, the planning and community development department select us security over $300,000 grant to continue and improve the work at the reservoir the restoration project there, which I've been following for a couple of years and I'm really excited to see that near completion and the thrill for the walking paths in the parking lot to be open next spring. But again just kudos to that hard work to secure the grants it's really important for our financial picture and for improving the quality of life for the town. Thank you very much. Thank you Mr. Helmets, Mr. Diggins. Because I have to jump at 740 new business. Thank you. Okay, thank you Mr. Diggins. Mr. Herd. No business. Okay, thank you Mrs. behind. Why they, um, I just want to. Since I know we have Susan Gilbert and other members of the news media. I'm tuning in that the town of Wellington opened up the reopened the COVID rent relief program. And we have information on the town website for people who may have applied for that in the past or may not have that that is once again open. So I definitely wanted to highlight that. I would leave with the town manager Mr. Chaplain if I'm sort of following up with his remarks. I know we had a very successful and early booked third booster vaccine at Town Hall for the residents of Wellington. I know there were a lot of residents that tried to book slots but they went quickly. So, if Mr. Chaplain could let us know through our health and human services director. If there will or will not be on another opportunity for that, which is fine either way I just want to be able to tell people. There is something come up coming up. Please check the town's website Facebook, Twitter, Instagram, however we are, or if myself and my colleagues say, you know, check out your PCP your pharmacy CVS Walgreens and get it that way. I would just like to, I have three and four three is, and I know the chair and I shared an email about this, but I want to reiterate that in terms of when we were discussing premium pay for town essential workers not for town residents that I know I asked for, and I think, perhaps in the same vein is to herd was asking something similar to see the premium pay formula that the town manager has come up with. I just want to see what the formula is. I know the number of employees. I just want to do the math. I just want to get involved in negotiations, although it's my opinion that premium pay for essential workers that's not a negotiable and can't be a negotiable point. There's no town employees on tonight. Because that has nothing. It's federal funding, which has nothing to do with town negotiations. So again, I really want to see that. And then lastly, for a future meeting. I just want to bring to the chairman and my colleague's attention. And I have had conversations with Mr Chaplain on this regarding the L life nifty's permit. The waiver that's coming up soon. I'm starting not only the combined sewer overflows CSOs that discharged in the book from Cambridge ensemble. But also the flooding issue. So I'd like to put that on a future. And I'll speak further with the chairman and town manager on this, because starting in. I believe next January, the town needs to have its comments on the upcoming it's every 15 years that the nifty's permits open up. But there's also some residents led by Kristen Anderson, who's a town meeting member who's very knowledgeable about this issue. And who would like to speak to all of us on the board regarding the current nifty's permit that's in effect, and how Cambridge and or some of them in MWRA committed to the current nifty's permit to do some things and that hasn't been happening. I don't want to go into that because I'd like person to present that because I don't I don't want to take some comments she would like to make for that. I will, and I will speak with the chair, Mr. Corsi and Mr. chapterling the town manager about having that on perhaps in December or January for sort of quick agenda item, because the town did take some steps at the MWRA in the city of Cambridge and some of them committed to. But then when the DCR Department of Conservation and Recreation. And the city of Cambridge and I renovated the areas down there. They took down. One of the major points that we wanted on the nifty's permit for notification so that's it for my new business. Thank you. Thank you, Mrs. Mahan. Yeah, and I briefly just have one or two things before I get into that. We had a very limited agenda tonight because we added this meeting just for the sole purpose of approving or accepting the 21 precinct plan. We have a full meeting next Monday. We will have open forum and we'll have a full agenda on that evening next next Monday. I wanted to follow up on something I spoke to the town manager about this today, but we've been getting a number of calls at the select board office about the yard waste pickup in town and concerns about that. And there is a message on the recycling page on the town's website. I think there are still some issues that do what the town's asking is don't call jrm directly the town is working with jrm that have been delays but I'm a Monday pickup. And this is now the second Monday that there's been no pickup in our neighborhood so it's what's what's on that site right now. I think jrm is even further behind them. We realize I know they're working through this and we need to be patient but I'm hoping if we can get some updated information for residents and continue to work with jrm on this issue because it's it's it's it's getting confusing to people in terms of how long this is going to be because there's only one more week left. Our yard waste pickup the week of December 6 so I want to acknowledge the calls that residents have been making and let people know that the town manager and the DPW director have been working with jrm that there's a number of challenges this year that they're they're trying to work through and hopefully updated information can be provided soon on that. The other thing I just wanted to acknowledge I want to acknowledge Christine char council on aging the council on aging had run a Thanksgiving meal on delivery last week and she ran that and that was very successful and thank her for her efforts Christine char council also went down and had participated in that knows a number of volunteers so that was a big success so that's that's my new business for this evening. We are now going to go into executive session. I believe we're only going to come out of excess executive session to adjourn the executive session is to consider the purchase of real property 21 maple street and when we come out of executive session into open session will be there solely for the purposes of adjourning. Thank you. Is there a second. Second. Second by Mr. Hurd. Okay on the motion by Mr. Hurd. Mr. Chair and Madam Vice Chair can I just confirm one thing that it would be potentially a problem that would be potentially disadvantageous for the board's bargaining position to have a discussion in open session. Thank you. Thank you very much. On the motion. Mr. Hurd. Yes, Mr. Diggins. Yes, Mr. Helman. Yes, Mrs. Mahan. Yes, thank you. Mr. D'Corsi. Yes. Thank you. So for those participants who are on we'd ask you to leave the zoom call and we'll just take a couple minutes before we start. Thank you.
