BAR is a really great RTS game. By far the best one today. It is very balanced and has a lot of depth. Highly recommended for any RTS enthusiast.

It’s been 17 years since I got my first Linux job in 2008. Where I live, that’s rare, 99% of the industry here is a 'Microsoft Shop,' and the biggest player in town is practically married to them. I started out at a small Linux co

Do not buy Kioxia. If your drives dies after a few years, but can come back to life with an firmware update. They will not give it to you unless you have a support contract. Solidigm have all their firmware available for everyone their webs

As a startup, what is it in for me to switch from Java, Spring Boot, Hibernate, Beam, Flink, Pulsar, Vault, KeyCloak ecosystem to C#.Net? Is the documentation better? Do I get better performance? Is the community larger and more stable?

A standalone Pulsar, is actually a great way to learn Pulsar. It is one command to get started: bin/pulsar standalone It can also be used in production. You do not have to build a distributed Pulsar cluster immediately. I have multiple

TrackerFF sounds like someone on the left trying to defend the wealth tax. As a Norwegian who believes in freedom and the right for anyone to start their own business, I think the wealth tax is one of the most toxic taxes ever introduced. I

Mattermost is open source, but the licensing is complex and full of bullshit. It is not a community driven project. Once you have installed the self hosted solution, you get a user interface that asks you to upgrade to the enterprise editio

The last 15 years, servers has gone from 3x memory channels to 12x, while desktop still only have 2x memory channels. It is by far the biggest bottleneck today.

I love Debian, but it does have some weaknesses. For example with virtualization, when you enable SR-IOV, apparmor goes bananas. With AlmaLinux + SELinux there are no problems. I use both Debian and AlmaLinux on my servers, and with that co

If you have many beans that does IO, startup will be slower. For example, just removing sql/database initialization can shave off a second.

Before I knew about Keycloak, I need to figure out how to use Spring Boot to authenticate via Azure Entra Id. I could't use Spring Boot Security OAuth2 as I couldn't figure out how to bind Entra ID groups to roles in Spring Boot.

I disagree, the wealth tax is the issue. The reason the wealth tax is an issue, is that making investments becomes a burden. Norwegian owners have to pay 2.1% of the company value every year as a tax, and when you invest, it can take 5-10 y

As a Norwegian, I can say that living here is awesome. Unless, you're a business owner, a founder, or have no work experience. The effects of the wealth tax has been insane. Businesses no longer have money to invest and every business

You do, the normal way is to create a special metadata devices of mirrored SSD's. You do not need a 3 way mirror, as ZFS by default stores 2 copies of your metadata.

I experimented with spindowns, but the fact is, many applications needs to write to disk several times per minute. Because of this I only use SSD's now. Archived files are moved to the Cloud. I think Google Disk is one of the best alte

How many of the Apache Kafka issues are adressed by switching to Apache Pulsar? I skipped learning Kafka, and jumped right into Pulsar. It works great for our use case. No complaints. But I wonder why so few use it?

Actually this is not important. Because they need to make a living, and with that they have to make some functonality of ClickHouse propritary. You can scale the pure open source project really far. And if you need more, you do have money t

That is true, though the implementation is weird. I mount my nfs shares like this: sudo mount -t nfs -o nolocks -o resvport 192.168.1.1:/tank/data /mnt/data -o nolocks Disables file locking on the mounted share. Useful i

Web development is super simple as long you use a mature stack. Just use HTML/Server side rendered templates, CSS and Vanilla JS. Then you need a mature backend framework, Spring Boot, Rails, Django and then you need a database, SQLite
