Great article! After reading I started to think there must be some purchable items which would demonstrate colours outside P3 colorspace. It would be cool to hold one on your hand and experience how a photo of it just cannot do justice.

Anybody know any links to webshops for such items?

Another examole which is trivial with MCP but hard with cli binaries: blocking certain commands, such as write operations from the agent. With MCP your client can easily have a blocklist for commands, but with cli you would need to code custom logic for each cli separately.

MCP has a great advantage over agent using cli: MCP is much easier to secure so that it's hardwired that the agent can only call the pre-configured MCP server. We run our agents so that they don't have access to public internet, so they could not run any cli commands. It's all either built-in agent tools, or 3rd party mcp servers. The agents never have access to any credentials, which makes them much more safe to use than a claude code running in yolo mode with fetching random cli binaries from the web.

I'd love to get this as a self-hosted web service, so that I could access my infinite terminal canvas from any browser. It should of course held the sessions in the background even when I'm not connected.

Often, especially on competitive games, the server is basically a full client, but just without graphics. The server will often run physics simulations etc, so that it can validate that nobody is cheating.

Sure, in some cases you can roll your own server, but often it's impossible.

The radar "reading" was done by first plotting analog radar signals to the antique rotary radar displays. Then there would be human operators with a light pen, marking each radar signature on each radar turn.

So the Univac would receive input coordinates for each target and track those in memory each turn.

mrgaro — Wed, 18 Mar 2026 12:45:17 +0000

CPU's microcode can be surprisingly simple: The CPU has bunch of internal signals, which activates certain parts of the CPU and the logic when to turn each signal on comes from reading bunch of input signals. The microcode can be just a memory where the input signals are the memory address and the output is the control signals.

Not hard, but time consuming. In the past two weeks I've had Claude Code write me around 35k lines of code across 350 commits. It's a project which is giving positive impact to the company, but we would never have started it without CC as the effort would have been too big compared to the impact.

I'm an avid user of the Claude Code planning feature and I like how Claude Code asks for questions. I also often iterate the plan before finally giving it a go.

How do you solve this in Kelos?

I tried to check the code base, but it didn't really provide any glues. I guess I could instruct the agent to build a plan and to post the plan in the issue and then iterate that with written comments in the issue. Is that how you run it?

There are companies which are only serving open weight models and not doing any training, so they must be profitable? Check for example this list https://openrouter.ai/meta-llama/llama-3.3-70b-instruct/prov...

Not sure about that. My Android warns me about my wife's airtags so often, that if I would actually be tracked by a malicious airtag, I would just assume it's one of my wife's tags. This could be prevented if I could mark a tag to be trusted on my Android phone, but no such feature exists.

I was just helping my dad with a brand new Lenovo laptop with Windows 11. It felt unbelievable slow and sluggish. Just opening file manager to create a new folder lagged so much it felt like this would have been a 15 years old computer.

I remember having this argument with my professor at the school, who insisted that a function should have only one "return" clause at the very end. Even as I tried, I could not get him to explain why this would be valuable and how does this produce better code, so I'm interested on hearing your take on this?

There are missiles in which the allocation rate is calculated per second and then the hardware just has enough memory for the entire duration of the missile's flight plus a bit more. Garbage collection is then done by exploding the missile on the target ;)
