I know what I see in my apps. Yes, Azure is worse than AWS. AWS has its flaws, but Azure is simply very slow in comparison.

I must say as a long time windows developer, .net core on linux is much simpler than on windows. I'm moving everything I have from windows to Linux and the experience, simplicity, speed, stability, etc are much better on linux. I guess

I completely agree. For some reason they're not 100% ssd and that changes everything. That is the main reason I avoid Azure. Last time I tested (about 8 months ago) I got a new windows server instance with 4gb ram and do a windows upda

I find it hard to believe that any decent chipset made in the last decade at least cannot support 32gb of ram. I had a reasonably cheap samsung laptop from 2012 that already did. If apple is not doing it, it's not by the lack of choice

Yes, but this is new to mysql 8, which is pretty recent. Also, I always use uuid v4 to explicitly prevent any ordering.

I ended up reducing the number of clients. In my case I had a thousand servers, and I was able to change the application structure and merge them into a dozen big application servers. Now with connection pooling each server has less than 10

MySql doesn't have a UUID data type, the UUID() function returns a varchar. The way you store it is mostly preference and driver defaults. The C# driver used to handle binary(16) as Guids, then they deprecated that in favor of CHAR(36)

I had some real issues with mysql handling more than 2000 connections. Once past that limit, cpu usage increases exponentially with few connections due to context switching. At 3000 connections, 80% of thr cpu was used gor context switching

I think it's different. From the docs, this is a one time update to the table. The table itself is not clustered, it's just ordered based on a clustered index, so selects by default should come in that order. But once an insert is

I use UUIDs in mysql as primary keys in tables with a few million records, and I'm about to migrate a few tables with billions of records from bigint to uuid. Never saw any real problem. I use char(36), as it's easier to query man

If you have a small number of requests over a large period, serverless is cheaper (that includes an api that is idle most of the time and peaks at a very high rate occasionally). But once you go live and start to grow, there is a point wher

I don't have the numbers here, but I'm pretty sure the same idea applies for serverless. If you have a predictable load, you can always find a much cheaper alternative once you pass a certain threshold. The cloud is never about co

You're completely right. You can get an amazing server in a very good hosting provider at a fraction of AWS. Really. You can get for $200/month a good server in a good hosting that costs literally $5000/month or more on AWS.

What is terraform? Read the page, but didn't get exactly what it does.

Doesn't MS One Drive do that for ages now?

Please define "very large". When I think large app, I think at least a few hundred endpoints split across tens of thousands of files. How can you have a very large app with a single endpoint? Could you elaborate?

I regret publishing some ideas I had as an open source project. Once it got other people's attention I had so much work trying to document, answer issues and maintain the project that in the end I got tired of it all and had to stop. I

That was very pessimistic, but I can see some truth in it.

EBS optimized VMs looks nice on paper, you can choose the size and pay for your needs only. But the once you start to use the disk in production you see the problems. In short, if you want to use the disk a lot, you need to pay a lot. If yo

Agreed. After a lot of struggles trying to find a good average IOPS on AWS for our database, we just increased disk to 1tb with gp2 and got rid of the problem. It gets 3000 iops/sec all the time and you never have these problems. It&#x

I work with someone who uses ligatures. Everytime I need to see his screen is a problem, I can never recognize what exactly the characters mean. Yes, you get used to it if you use it, but if you don't, working with other people becomes

I work with someone who uses them and I find it impossible to read his screen. Unless you work completely alone, it's a terrible idea.

rimraf is extremely fast. Started using it to delete large node_modules folders and got used to it.

After looking at the website, it still took me some time reading the comments to understand what it does. It's an open source version of pocket you can host yourself, and if you want, they host for you for 12 euros a year. It's in

Yeah, but I didn't point out what mysql should have done in an alternative universe. Mysql DOES support fixed lenght unicode, just use the correct encoding: ucs2 or utf32. What it does with utf-8 is what any system that supports utf-8

I find it amazing that Python 3 is almost 10 years old and it's still not been able to replace Python 2 everywhere. I mean, legacy is one thing, but from what I see lots of people still start new projects with python 2.

Google earns a lot from advertisement, but they're not just showing ads, there is a difference. You're actually paying them to find the right customer to show the ad. And that probably will always be valuable. Much different from

Not sure what deserved a downvote here... Is there anything incorrect?
