it's funny that your comment also feels very LLM-generated.
Um, yes. That's the entire joke.

These LLM-generated blogs aren't going away – they're everywhere. And the best part? You can now instantly push out garbage content at no cost. Traditional writing is not just dead. It's legacy. The real marketer doesn't care. He just slops.

I have no doubt they know what they are doing. But it's a srange metric no matter how you slice it. Why compare AV1's bandwith to the average of h.264 and h.265, and without any more details about resolution or compression ratio? Reading between the lines, it sounds like they use AV1 for low bandwidth and h.265 for high bandwidth and h.264 as a fallback. If that is the case, why bring up this strange average bandwidth comparison?
Yeah it's a weird comparison to be making. It all depends on how they selected the quality (VMAF) target during encoding. You couple easily end up with other results had they, say, decided to keep the bandwidth but improve quality using AV1.

> AV1 streaming sessions achieve VMAF scores¹ that are 4.3 points higher than AVC and 0.9 points higher than HEVC sessions. At the same time, AV1 sessions use one-third less bandwidth than both AVC and HEVC, resulting in 45% fewer buffering interruptions.
Just thought I'd extract the part I found interesting as a performance engineer.
This VMAF comparison is to be taken with a grain of salt. Netflix' primary goal was to reduce the bitrate consumption, as can be seen, while roughly keeping the same nominal quality of the stream. This means that, ignoring all other factors and limitations of H.264 with higher resolutions, VMAF scores for all their streaming sessions should roughly be the same, or in a comparable range, because that's what they're optimizing for. (See the Dynamic Optimizer Framework they have publicly posted a few years ago.)
Still impressive numbers, of course.
I haven't had much luck with skills being called appropriately. When I have a skill called "X doer", and then I write a prompt like "Open <file> and do X", it almost never loads up the skill. I have to rewrite the prompt as "Open <file> and do X using the X doer skill".
Which is basically exactly as much effort as what I was doing previously of having prewritten sub-prompts/agents in files and loading up the file each time I want to use it.
I don't think this is an issue with how I'm writing skills, because it includes skill like the Skill Creator from Anthropic.
Same experience here – it seems I have to specifically tell it to use the "X skill" to trigger it reliably. I guess with all the different rules set up for Claude to follow, it needs that particular word to draw its attention to the required skill.

That article is a classic example of a prevalent error in this line of commentary: indiscriminately taking a "possibly harmful chemical", translating it to a totally different context (say, touching it instead of eating it), and then assuming that any interaction with the chemical is therefore bad.
The article specifically calls out pthalates and bisphenols (both common in plastics), but there's absolutely no reason to believe -- unless you're regularly eating your headphones -- that this is a problem.
Totally agree with you - the dermal exposure is a different pathway, and that could be more clearly mentioned. The fact that these materials are present are not automatically hazards (but they do state that!). I also wouldn't automatically assume that the products marked as red are not safe to use. For me it's just interesting to see that some manufacturers can do without, or less of those components.

The Austrian consumer protection association has just released results on tests of headphones: https://vki.at/Presse/PA-Kopfhoerer-2025 (German article), and found that 40% contained possibly harmful chemicals, including the parts that touch your body.
It's wild. I have children, and I spent a great time researching foods, bottles, toys, etc., but I would've never thought much about doubting the (big brand) consumer electronics that we all use every day.
slhck commented on FFmpeg 8.0 adds Whisper support code.ffmpeg.org/FFmpeg/FF... · Posted by u/rilawa
The only problem with this PR/diff is that it creates just a avfilter wrapper around whisper.cpp library and requires the user to manage the dependencies on their own. This is not helpful for novice users who will first need to:
1. git clone whisper.cpp
2. Make sure they have all dependencies for `that` library
3. Hope the build passes
4. Download the actual model
AND only then be able to use `-af "whisper=model...` filter.
If they try to use the filter without all the prereqs they'll fail and it'll create frustration.
It'd be better to natively create a Whisper avfilter and only require the user to download the model -- I feel like this would streamline the whole process and actually make people use it much more.
While that would be nicer from an end-user perspective, it's something hard to maintain for FFmpeg itself. Consider the velocity of the whisper-cpp project. I'm sure that – just like with filters such as vmaf, which also require building a dependency and downloading a model – precompiled versions will become available for novice users to directly download. Especially considering whisper-cpp is MIT-licensed.
It is a bit off-topic here, but anybody tried to use such LLMs for code porting: from c++ (and similar) to plain C99+?
Yeah, look at what https://x.com/badlogicgames has done porting an engine with the help of Claude Code. He's set up a TODO loop to perform this: https://github.com/badlogic/claude-commands – background blog article: https://mariozechner.at/posts/2025-06-02-prompts-are-code/

Love this feature of UV. Here's a one-liner to launch jupyter notebook without even "installing" it:
uv run --with jupyter jupyter notebook
Note that it's not really "cleaned up" insofar as there is a uv cache folder that will grow bigger over time as you keep using that feature.
