fh973··on How Europe is killing makers and micro-entrepreneurs
Or just ignores them, if it doesn't serve the lobby groups, like for example the EU Water Framework Directive (WFD).
fh973··on Oomwoo, an open-source robot vacuum you build yourself
Valetudo is an API proxy to control robots via an associated app in order to avoid vendor clouds.

It is not a robot firmware and has no role here.

fh973··on Ask HN: Is anyone working at least 4 hours daily on an Apple Vision Pro?
Balance presumably.
fh973··on We made our filesystem 47× faster by deleting it
FUSE is not slow. Our distributed file system pipes over 70 GB/a through a single mount point.
fh973··on Lunar Flyby
The missing piece of information: the moon is not perfectly sphere shaped, the bulge has more mass, and is attracted by the earth more.

fh973··on End of "Chat Control": EU parliament stops mass surveillance
Gmail and likely others have been scanning at least emails for child pornography since the 2010s.
fh973··on We do not think Anthropic should be designated as a supply chain risk
No mass surveillance of Americans it is.
fh973··on Flying Around the World in under 80 Days
Sorry, but that's just ignorance. It's an UAV, it's not registered, has no type certificate. He doesn't even seem to be aware of airspaces.

So no, it's not legal in many ways.

fh973··on Sparse File LRU Cache
Most compressible file formats are already compressed, and with compression you lose efficient non-sequential IO.
fh973··on Microsoft suspects some PCs might not boot after Windows 11 January 2026 Update
VR?
fh973··on The 'untouchable hacker god' behind Finland's biggest crime
German government and courts are as opportunistic as everywhere else. German government ignores EU laws (ex: water protection), its own courts (ex: air pollution court orders, time record keeping for teachers) and worker protection (ex: false self employment of music teachers).
fh973··on The housing market isn't for single people
What has changed is that dual income became the norm, and is no longer an advantage, but mandatory to compete on the housing market.
fh973··on European Commission issues call for evidence on open source
This app currently runs on Android or iOS.

Anyway, open source is fine there. But you're not getting things like a Desktop or Web office suite (OpenOffice is an historical accident), an enterprise device management, endpoint security, ... this way.

fh973··on European Commission issues call for evidence on open source
Europe does not need more open source, it needs its own healthy and competitive software industry.

It doesn't matter if the email platform a government uses is open source, but it should be able to pick a local alternative. It does not matter if the e-ID or payments app is running on an open source mobile OS, but it should be possible to run it on a non-US one.

Policy may help the European software industry, at least governments should actively work on getting away from their Microsoft addiction. Open source may be one of the options, but it is not the right model for all types of software.

Blindly preferring open source may kill otherwise viable local software businesses.

fh973··on Modern cars are spying on you. Here's what you can do about it
Checked how to receive those with SDR. Turns out they are very low power and you need to basically touch the tire. Also the transmit in minute intervals. Bit exactly a a smoking gun in terms of mass surveillance.

fh973··on I wish SSDs gave you CPU performance style metrics about their activity
Queues tend to be always full or always empty (see queueing theory). There is no steady state with a half full queue.

For NVMe in particular you will have a hard time filling their queues. Your perceived performance is mostly latency, as there is hardly an application that can submit enough concurrent requests.

fh973··on Despite what's happening in the USA, renewables are winning globally
Aren't panels commodotized? Many western countries could probably spin up production at scale if needed and economically viable. But why do so now?

Also why talk only about panels. Inverters are cost wise in the same order of magnitude, but much more complex artifacts.

fh973··on I ditched Docker for Podman
Docker swarm is great on single servers. Apparently still no such thing for Podman.

Even if the tech is not top notch, Docker got a few things right on product management.

fh973··on WiFi signals can measure heart rate
Max. 16Mbit in Berlin-Schöneberg here.
fh973··on Lucky 13: a look at Debian trixie
Indeed, with the tmpfs move (tmp in RAM) however it sounds like they have more Desktops in mind.

You don't want to use RAM for tmp files for which you probably can't do capacity planning, and you don't to enable swap on server either.

fh973··on A deep dive into Debian 13 /tmp: What's new, and what to do if you don't like it
Swap on servers somewhat defeats the purpose of ECC memory: your program state is now subject to complex IO path that is not end-to-end checksum protected. Also you get unpredictable performance.

So typically: swap off on servers. Do they have a server story?

fh973··on Nvidia DGX Spark
Ordered one in spring. Delivery time was pushed from July to September. Apparently they had a bug in the HDMI output.
