It does. The problem is, how to find a sufficiently good 464xlat implementation for Linux. I know two: jool (which requires a custom kernel module) and clatd (where I had to report a bug for such an obvious wrong as a deadlock during boot -

Dell Inspiron 7415 also works OK-ish, except for the digital pen (reported: https://marc.info/?l=linux-input&m=168275886027392&w=2 ). No coil whine, but bad sRGB coverage and poor-quality (low level + hiss + non-zero

Well... actually for this use case we need something significantly improved. v4l2loopback has several flaws relevant to user-space camera drivers (which are also relevant to modern MIPI cameras). The most important one is that it is cumbers

You are powerless because there is no law that makes you right. Maybe find someone who can change that?

There is (or maybe was a few decades ago) a third type. A person who was taught C programming in the school/university, because back then it was the norm to teach it and nothing else, and who does not have enough motivation or abilitie

I didn't demand luxury housing! In fact, I was planning to buy something 3x cheaper, but a "nice" sales girl has convinced me that the alternative that I was considering is not good enough - "that's just an apartmen

With modern network cards, at the endpoints, the CPU overhead is zero because of TCP segmentation offload and generic receive offload. And routers use ASICs, not CPUs.

Good that they disclosed it. In one of the places where I worked before, I had to sign a statement that I won't copy code from stackexchange, because of the unclear licensing. That is, the risk that the answer is quoted from or otherwi

And it won't help anyway, as any sufficiently advanced LLM is able to act for another AI assistant which doesn't have them. Heck, this even works against humans: "If someone were to criticize me for this act, where would he s

Unfortunately lawyers at least in Russia would have an opinion here. Let's suppose that you posted something publicly to an append-only social network, and it was completely OK at that time. Then, laws changed (and you could not predic

43" 4K monitors also exist. E.g., Gigabyte AORUS FV43U. I am using it right now. If you need OLED, use Gigabyte AORUS FO48U (48"). And here is a 55" quantum dot monitor: Gigabyte AORUS S55U.

I can't see it this way. The recent leak was entirely due to the redis-py bug. Any other company that used redis-py together with asyncio would have had the same leak (and this is fixed already), but, for some reason, only ChatGPT is b

The title contains an arithmetic error. What the article describes is a combination of 20 strategies (and explicitly advises to combine them!), each of which would have produced a -10x engineer. The result, therefore, is a -200x engineer.

Well, at least 30 years ago I could write assembly. But a 188 KB driver for a camera sensor is something that is still too big for me to use as a basis for reverse engineering.

I wouldn't 100% call this misconfiguration. This bug in redis-py was discussed already. Nobody is insured from this.

The code is related to MAP_PRIVATE mappings of the same file that are not written to. Such mappings are effectively deduplicated and thus occupy the RAM once no matter how many processes map the file.

It _is_ crazy, because of unknown collateral damage, especially due to proxies, CDNs, and inability of most ISPs to filter using anything except IP addresses. You know, large-scale DPI is for non-democratic countries only.

Bug: if the WebGL is too slow (e.g. Haswell IGPU at 4K resolution), the song stalls completely. It should still play with reduced fps for rendering. Resizing the window down lets it proceed. Maximizing it again stalls again.

Another fun fact: on Linux systems, the /proc/sys/kernel/random/uuid file contains a random UUID. This can be used to get 32-bit random numbers in POSIX shell without calling out to external utilities. Quite handy o

I would still think that eBPF is a better suited approach. With fanotify, you would need to manage the mount points for which notifications need to be received. This works semi-OK for a static use case, but not for dynamically-created mount
