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
Marketing material says NVIDIA DGX™ OS, which at version 7 would be an Ubuntu 24.04: https://docs.nvidia.com/dgx/dgx-os-7-user-guide/introduction...
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.
fh973··on Privately-Owned Rail Cars
Zeppelin is operating daily sightseeing flights in several areas of Germany https://zeppelinflug.de/en/zeppelin-flights
fh973··on Fuse is 95% cheaper and 10x faster than NFS
At Quobyte (https://www.quobyte.com) we use FUSE for the client for parallel file system access.

You can get dozens of GB/s out of FUSE nowadays. This will even improve in the near future as FUSE is adding io_uring support for communication with the kernel (instead of a pipe).

fh973··on South Korea's military has shrunk by 20% in six years as male population drops
1 soldier in the battlefield needs several soldiers as support (logistics etc.).
fh973··on US reportedly forcing TSMC to buy 49% stake in Intel to secure tariff relief
Them? Nvidia and AMD? RTX 7xxx would then be based on an old Intel process? Would buy these?
fh973··on Micron rolls out 276-layer SSD trio for speed, scale, and stability
An SSD with 2TB flash typically contains 2GB RAM for lookup tables.
fh973··on Linux Reaches 5% Desktop Market Share in USA
I think the year of Linux on the desktop will actually be the year of Chromium on Linux on the desktop (instead of Chrome on Windows), ie. is it really the Linux on the desktop if the only application you run is the browser for SaaS anyway?

fh973··on Modern C++ – RAII
Yes, it is very inefficient, as it is thread-safe and uses atomic operations internally.

So instead of just accessing memory, you have the cost of cross-cache coherency operations between CPU cores.

fh973··on Microsoft is killing Skype
In Germany, MS was very successful though to get organizations on Teams during the pandemic. Zoom is not a thing.

Sure, it's nice to brand the verb, but when the product behind it is EOL, why bother.

fh973··on We're accelerating the Android XR platform with a new agreement with HTC
Flight simulators
fh973··on German watchdog orders Sam Altman's biometric ID project World to delete data
Encrypt it and delete keys.

At least Microtik doesn't have a switch with 24+ 2.5GigE ports.
fh973··on OpenWRT One Released: First Router Designed Specifically for OpenWrt
Speaking of which... anyone know why there don't seem to be any managed 2.5 Gbit switches / chipsets? Can we expect them in the foreseeable future?

fh973··on Apple releases Depth Pro, an AI model that rewrites the rules of 3D vision
This article has a link to the live demo.

https://huggingface.co/spaces/akhaliq/depth-pro

For some pictures it outputs something reasonable, for others it's completely broken (black with colored noise in one area).

fh973··on Houston Is on a Path to an All-Out Power Crisis
> “Why did so many CenterPoint power lines and poles snap so easily? Why wasn’t the grid built stronger, and why wasn’t vegetation cut away?”

Why not put power lines under ground, like other countries do? It's probably more expensive, but large scale repairs or rebuilds several times a year do not sound cheap either.

fh973··on Barcelona will eliminate tourist apartments
Building companies don't own the apartments, banks do. Lower effective prices means writing off debt.
fh973··on Fern Hollow Bridge should have been closed years before it collapsed
This is all interesting, but misses the point: the bridge collapsed due to a social (management, responsibilities, organization, ...) failure. Investigating the engineering story distracts from that, both in the video and apparently effectively as there is a NTSB investigation and not mentioning if any organizational review if the same rigor.
fh973··on Proxmox VE: Import Wizard for Migrating VMware ESXi VMs
I really hope that the price increase creates a business opportunity for new technology. This space has been plagued by subpar "free" alternatives (Openstack, Kubernetes) for a decade.
fh973··on Airfoil
It's relevant in practice when landing against head wind. You need to have extra speed to not stall when you enter the slower air near ground.
fh973··on A Distributed File System in Go Cut Average Metadata Memory Usage to 100 Bytes
The Quobyte DCFS does end-to-end CRC32 for each 4k block of data. All metadata and communication is also CRC protected, although one other frame boundaries.
fh973··on Mixed Reality gone in Windows 11 Insider Preview Build 26052
They developed MSFS 2020, which is the killer app for VR headsets, and announced a successor already. At least there seems to be some strategic misalignment.
