I use Grails, which is Spring Boot with sane defaults already configured. Grails is very similar to Rails, while Spring Boot still involves some configuration.

The cloud is great for scaling indeed, but a cheap Intel V4 server with 44 cores from Ebay for $2000 can handle a shit ton of traffic too. If I were building a new business, I would use both cloud and colo. But I do understand that everyone

My workstation is Linux, which I mostly use. Though I have a MacBook laptop that I also use. So I voted for Linux, though MacOS is a close second. I also use Windows for development, but that is only when I do Windows specific stuff.

All servers are behind a NAT, but the servers are only configured with SSH open. With the exception of the NAS I am using which also has NFS, iSCSI running. Also, only the backup servers are allowed to make connections to NAS I am using. Th

Not really, space has been free for me. Electricity is very cheap usually here in Norway. And hardware are used servers from Ebay. Though these are actually desktop AMD x2 with 8GB ddr2 ECC memory on Asus motherboards. Still working fine, b

Packaging, pre-sales and support. I had a very good margins, so overall it wasn't a bad business with long hours. For many this would have been fine. But for me it got boring really quick, shut down after about 18 months.

I quit a normal job in 2015 to do freelance consulting. I had no plan, luckily I found two clients for part time work and for the rest of my hours I created a e-commerce site that I operated for myself. That quickly escalated and made more

If you are using ZFS, I strongly recommend using LZ4 or ZSTD compression with PostgreSQL. Performance is still awesome. On average I get 2x compressionratio with LZ4 and 4x with ZSTD. With this, you are compressing everything, not just colu

I've had a the smallest cloud instance for a few years now, it is in fact really good and fast. 1vcpu with 2GB ram is plenty for a full stack web application + a database. IO is also very good with stable ~8000 iops write performance f

It should work fine as long you're using the CPU, but it is not accelerated using the Apple’s ML Compute framework. Tensorflow supports it though.

ssh with zfs send/receive. No problems having hourly backup of your most important petabyte scale data on the other side of this planet.< I even do this with Microsoft SQL Server using iSCSI.

Same thing with the Grails framework, which is another Rails framework for Java eco-system. After Grails got refactored between 2.x and 3.x which broke all plugins, most new Java projects went with Spring Boot. Popularity of the Grails fram

Not really, I've learned a lot from the PostgreSQL documentation and various Stack Overflow answers. Like with everything, getting experience and your hands dirty will make you far more knowledgeable. There is no silver bullet.

If you read the link about pg_upgrade, you're not guaranteed that pg_upgrade will work if the underlying data storage format changes. pg_upgrade may not work in a future version of PostgreSQL. It works for version 14 though.

This is one of the major pain points with PostgreSQL. Unless you absolutely need any new features and uptime is important, you can just continue using PostgreSQL 9.6 even thought it is EOL. https://www.postgresql.org/support

Like some football players, some software engineers are a LOT better than others. The measurement is value in $, which easily can be translated to 10x-1000x better.

On Ebay you can find Dell R210 ii with Ivy Bridge CPU for 150 USD. These idles at 25watt, and are super quiet and small. I have not tested the R220 with Haswell, but I guess idle watt usage is less than 20watt as Haswell had much improved p

Oracle does a really good job improving the Java language. I really don't see any reason for why I should start using Kotlin. I use Groovy when I just need to do something fast without all the boilerplate code. But for 95% of the busin

I have evaluated these different options. And by far I prefer Clickhouse when were talking about less than a petabyte of data. It super simple to install and setup. And is a lot faster.
