When you see a societal pattern that is physically, and mentally bad for your kids why would you want them to fit in with it?

My wife and I also have three kids that share a simple flip phone, with no real access to social media, or the internet. A good number of their peer's do have unrestricted access to smart phone's, and as they have gotten older I t

but Spanner isn't Postgres compatible, they have their own transaction processing layer that is built for TrueTime. If this is using the Postgres frontend how are they incorporating TrueTime into the normal Postgres MVCC model that use

I appreciate the context, but this just adds so many more questions. How are you integrating hardware clocks into the Postgres transaction model? Is this just postgres wire compatible like Cockroach or Yugabyte, or have you modified Postgre

This sounds very exciting, but I would have greatly appreciated some actual technical details. From this statement > Sharded tables – These tables are distributed across multiple shards. Data is split among the shards based on the values

I would argue the best city for tech has never been the bay area. Its the best place to make a lot of money in tech, but by far the best engineers I have met, and the ones who have the happiest most well adjusted lifes do not, and never hav

I am pretty sure most people who work for Google and live in the south bay could tell you stories of having their car windows smashed in, and I do mean most. I think it is about 100% of the googlers and ex-googlers I know have had that expe

The article makes it seem like kids one day having a phone is a fait accompli, I like to think of smart phones as this generations tobacco. Right now it looks like a universal practice, but we already know the significant mental and physica

What about running PHP, Django, Node, or Ruby based applications ? They all do connection per request so the pooler on host gives you an immediate improvement to connection latency. Even if you are using a language with a built in connectio

Stackoverflow is very much the exception not the rule. Most of your top tier software companies have server fleets that scale well past the 10,000's of nodes level, and for container based workloads I don't think its uncommon to h

The constraint is less often the database in reality then in theory. Expecially when you consider many large scale applications are doing complex things. A normal request trace might only spend 30% or 40% of its time in the DB call. When yo

This might be the best explanation I have seen of the benefits and pitfalls of deploying pgbouncer ( or any connection pooler as they are all similar ). The only thing I would add is from a deployment perspective, you should run two layers

How does the network switch occur when you live migrate the VM? I see some mentioning of multus-cni, but I was not aware of anything in kubernetes that allowed you to migrate a network interface across nodes.

This is not at all true, if you wanted character to your community then the community should have approved a building plan that kept the character and allowed for more housing. As it stands these communities have said no to everything and n

This is a great entry point to split ortholinear keyboards. Build quality is great, its well supported, and its very easy to set up and get using it. The moonlander they sell is also pretty good. I like the ergodox style thumb cluster bette

You should check their quarterly earnings I think you would be shocked. In the second quarter Cable and Broadband account for 7.4 Billion in profit, and have a profit margin near 50%. NBC Universal only accounts for 1.9 Billion and their th

Its so expensive that Comcast only made a profit of 42 Billion in 2021, while providing a lower quality of service than what a small ISP in Michigan can give you for a one time 2M in government grants.

Is there a way to federate which keys are commonly accessed ? Like if I commonly access the entire table can I direct inbound traffic to different application servers and have them access different caches so each cache can pull only a subse

I am really excited to see where readyset can take this technology, if deployment is as simple as they say this sounds like an instant win for any high throughput service. I am curious how they handle queries that would overflow local main

I am really excited to see this project. I can't tell you how many times my team at work has hit a limitation with pgbouncer and swore up and down we should just re-write it in rust. Looking forwards to where the project goes!

I am glad that we can disagree, and I hope you would spend some time considering that while the research has progressed we have experienced a rapid decline in the subjective and objective quality of education. Just because I completely reje

You are correct that 30 is on the high side, but I have seen classrooms in Philadelphia with 30 students to a single teacher ( 3rd grade, during the 2005 school year so it may have changed since then). However even at lower ratio's the

The only thing distributed along the bell curve is adults who are willing to help the kids. Yes for some kids it will come pretty easy, even at very young ages, but even very young children can learn these concepts if you would just spend s

When I pulled my kids out of traditional school we started introducing concepts of Algebra and Geometry to them immediately (2st and 4th grades). It takes extra work, but they understand everything just fine. The problem isn't that the

You wouldn't do 40 completely unrelated things, they would be 40 aspects of a single thing. I would think 40 is getting a bit big as I have trouble getting stacks of more then 15 past a reasonable review, but the good news is ( at leas

Correct it is just the group of sequential commits. You can keep multiple stacks on a branch, but the big idea is the branch is not the unit of review, each commit is the unit of review

The big win for me is when someone reviews my code I can easily rebase the entire stack and push it back up for review, and thats all done with `git rebase -i HEAD~n`. That means when someone is actually reviewing my code its not uncommon f

I really didn't understand what the big deal was with Stacked Commits when I was just working in vanilla github, and it used to cause friction with members of my team who knew the stacked workflow, but didn't know the Github workf

I would encourage you to join the vitess slack channel and let them know of any issues you run into there. Resharding has successfully been done at massive scale, so its unlikely that the system can't handle the load. Here is the blog
