louiskottmann··on Make Tmux the OS
CachyOs with Niri and DankMaterialShell is what finally broke out of Ubuntu with Gnome.

It's slick, modern, efficient, and up to date.

I encourage trying that or similar.

louiskottmann··on The AI Race Just Got Awkward
Given they ingested basically the whole internet and then some, you cannot possibly be serious when you mean it's worth less than 10 billions.

The totality of the content on internet is worth several orders of magnitude more.

louiskottmann··on Creepy Crawlies
Isn't it perfectly reasonable to require an account for any use, and to ensure that making one has a high level difficulty anubis challenge or delay ?
louiskottmann··on GPT 5.6 Sol 20% price reduction
Claude really doesn't have that much market share. It's the most expensive by a mile but when you count token market share they're in the low %.

And everyone else is close enough in terms of quality, their tiny advantage if any is insufficient. Let's not even talk speed.

OpenAI is competing with chinese models.

louiskottmann··on Software Engineering fundamentals matter more
Thoughtfully and coherently factorized, abiding a set of architectural rules (i.e: we compose "this" way here, re-evaluated as we go) and following up-to-date framework conventions. LLMs are terrible at this.

Chosing OOP or FP is irrelevant, fundamentals matter more

louiskottmann··on A week in Matrix
Docker-compose setup (nothing fancy) on a dedicated server.

Usage is work, family and personal notes.

louiskottmann··on A week in Matrix
Acknowledged yes, adressed no.

Using dendrite at the time was a bet on the future : "use it now and you won't have to migrate".

You can also migrate by replicating messages, or mirroring new messages via a bridge.

In my opinion they tried nothing and they're all out of options.

louiskottmann··on A week in Matrix
AFAIR there is a doc about migration from synapse, that they promised to automate once dendrite would be production ready, which it never became.
louiskottmann··on A week in Matrix
Remark half-way in the rant they are using dendrite, an experimental matrix server implementation that has been abandonned. Thus ranting about it is cheeky at best.

I have been using synapse for years with little issue.

louiskottmann··on Love systemd timers
And you immediately lose the ability to do `crontab -l` on any server to know its scheduled tasks.

Now you get to look around the myriad of places where you can put systemd files, and figure out which ones are base services and which ones are custom, with no general convention to go about it. Nope.

louiskottmann··on The dead economy theory
History repeats itself : it ends in blood. Always does.

As the concentration of power happens, the people who concentrate it become bigger and bigger targets.

There is no alternative to wealth distribution.

louiskottmann··on I moved my digital stack to Europe
This is borderline adversarial propaganda.

While the incident did happen, a lot of actions were taken and most of the data was recovered. OVH now also keeps backups even for clients that don't pay for it.

I was hit by that datacenter catastrophe and got my data back almost immediately, in a new VM.

I've been using them for years with little issue (no more than happened on my AWS or Azure accounts, I would say less because it's less of a mess in general).

Stop spreading false rumors.

louiskottmann··on Redis array: short story of a long development process
That's my take as well, I find fixing poor/overengineered LLM code taxing.
louiskottmann··on Leanstral: Open-source agent for trustworthy coding and formal proof engineering
The linked article does not speak of tests, it speaks of a team that failed to properly review an LLM refactor then proceeds to blame the tooling.

LLMs are good at writing tests in my experience.

louiskottmann··on Italian prosecutors seek trial for Amazon, 4 execs in alleged $1.4B tax evasion
The trick is in the mud between what's yours and what's theirs. The induced doubt is lucrative.
louiskottmann··on Returning to Rails in 2026
I find the thought daunting but the reality surprisingly easy.

You just keep up as you go, as long as you keep things close to the framework it's fine.

louiskottmann··on Returning to Rails in 2026
I've been a Rails DevOps and nowadays a web one-man-show with it for over 10 years and I'd do it again.

Not many frameworks have been thriving that long, and there's good reason.

It packs everything, is tidy and productive, with a pleasant language to read and write.

In the latest Stackoverflow survey, it's back at the "top 5 of desired stacks to use for next project" over a decade after its inception !

Give it a try.

louiskottmann··on Gemini 3.1 Pro
You could get rich by solving ARC 2 tasks yourself instead of forwarding the work to an LLM, given a client willing to pay LLM rate.
louiskottmann··on WD and Seagate confirm: Hard drives sold out for 2026
People will find a way to not need as much RAM, and thus the devices that require it.

Same way the price of groceries going up means people buy only what they need and ditch the superfluous.

louiskottmann··on Show HN: Nogic – VS Code extension that visualizes your codebase as a graph
First of all, ruby-lsp does a great job at this, and the recent Herb helps with frontend templates.

This is enough to navigate between controllers, models and libs, unless you're trying hard to be clever which you shouldn't.

Then, in Rails, things have a canonical place in the codebase, that is consistent between codebases.

This is in contrast to languages and frameworks where every codebase is setup differently, but the static typing helps find code wherever it's hidden without pain, and thus without need for cleanup and thoughtful design.

To each their own, I prefer power for me, and pain for whoever drifts from the convention.

louiskottmann··on OpenAI's cash burn will be one of the big bubble questions of 2026
This is so obviously right.

I may add that investors are mostly US-centric, and so will the bubble-bursting chaos that ensues.

louiskottmann··on CSRF protection without tokens or hidden form fields
That's indeed a good example of prior full trusting of the browser by the server.
louiskottmann··on CSRF protection without tokens or hidden form fields
I appreciate that, but in the case of TLS or CSRF tokens the server is not blindly trusting the browser in the way Sec-Fetch-Site makes it.
louiskottmann··on CSRF protection without tokens or hidden form fields
This is a massive change for cache in webapp templates as it makes their rendering more stable and thus more cacheable.

A key component here is that we are trusting the user's browser to not be tampered with, as it is the browser that sets the Sec-Fetch-Site header and guarantees it has not been tampered with.

I wonder if that's a new thing ? Do we already rely on browsers being correct in their implementation for something equally fundamental ?

louiskottmann··on GitLab discovers widespread NPM supply chain attack
This is my take as well. I've never come accross a JS project where the built-in datastructures were exclusively used.

One package for lists, one for sorting, and down the rabbit hole you go.

louiskottmann··on OpenAI's H1 2025: $4.3B in income, $13.5B in loss
As history showed us numerous times, it doesn't even have to be the best to win. It rarely is, really. See the most pervasive programming languages for that.
louiskottmann··on Dear GitHub: no YAML anchors, please
Gitlab has had that for a while, and it's very useful as in-between through dot targets.

i.e:

.scoped-env: &scoped-env

   key1: value1

   ...
Dot targets are ignored semantically, only inheritors make them useful.

Then further down you can reuse *scoped-env wherever you need.

You can also have anchors on individual lines and compose them. It's useful.

The author suggests using ad-hoc syntax, or meta-keys. Gitlab supports that [1] and I use them as well.

Different but also combinable uses, for various people. Nothing wrong with it.

louiskottmann··on Sega mistakenly reveals sales numbers of popular games
There a lots of gamers. Games like Baldur's Gate & Expedition 33, which satisfies your criteria, far surpassed those numbers already.

I know people who rewatch the same TV series every year and go to the same vacation every year.

Fear of change is deep.

louiskottmann··on What would a Kubernetes 2.0 look like
I suspect it's a learning thing.

Which is a shame really because if you want something simple, learning Service, Ingress and Deployment is really not that hard and rewards years of benefits.

Plenty of PaaS who will run your cluster for cheap so you don't have to maintain it yourself, like OVH.

It really is an imaginary issue with terrible solutions.

louiskottmann··on Danish Ministry Replaces Windows and Microsoft Office with Linux and LibreOffice
That is stretching the subject beyond reasonable. Proprietary software as a general endeavor is not an invalid business and nobody is saying that here.

LibreOffice is close enough to Microsoft's offering that surely it makes sense accross the many EU states to stop spending millions on it, and spend a few to close the gap, saving even more millions in the future.
