12 is, in many ways, a better base than 10 (divisible by 2,3,4 and 6 vs 2 and 5). And it was used in many British/Imperial units. But the chance of the world moving existing systems from base 10 to base 12 is surely so close to 0 as makes no difference?

This is super cool. Of course, it is possible to separate instrument sounds using specialized tools, but can't wait to see how people use this model for bunch of other use cases, where its not trivial to use those specialized tools:

* remove background noise of tech products, but keep the nature

* isolate the voice of a single person and feed into STT model to improve accuracy

* isolating sound of events in games and many more

You shouldn't use reqwest on mobile devices, you should be using the built-in platform-specific HTTP libraries.

On Android this appears to be less of an issue, but on iOS there's documentation floating around that you really want to use e.g NSURLSession for battery/radio reasons. Spotify even went so far as to write a cross-platform lib for this kind of thing some years back.

Depending on how you look at it, there may be two distinct parts to this:

a) API to not just read notifications but also perform the notification quick actions (if any), e.g snooze for a calendar event, mark complete for a reminder, and of course reply for a text (SMS or otherwise). This seems entirely reasonable and ludicrous that it doesn't exist.

b) API to access SMS / Messages. That one appears to be heavily guarded because security / E2E (for iMessage).

I mention b) because a lot of times people invoke the problem a being b) (and possibly a problem in its own right, forcing one to use Messages for SMS) but really for watches a) is sufficient and probably much more relevant.

There's also a.1) API access
to media (images) in notifications.

In any case, DMA could definitely help crack both.

The only reason I keep my home PC with windows still is that I use it mainly to play games and some have anti-cheat systems that are not compatible with Linux. But I play those games less and less the older I get, I play mostly older games / emulators. I see it very likely that I won't install whatever comes after Windows 11 and at that point I might move over to Linux for good.

It is pretty obvious the cause, they are just doing their investigation. There is a video of it out there. I will describe it for sensitive people who might not want to actually see it. The car was going probably 100 mph out of a tunnel and understeered into a jersey barrier. The passenger was ejected still in the seat and the car caught fire a few seconds after impact. Bystanders managed to pull the passenger away from the wreck, then the video cut off.

First, I disagree that "user emails can be brute-forced" is a serious security issue.

I mean, sure, it's a security issue, but on a scale of 1-10, with 1 being "security issue, we'll fix in next point release" and 10 being "All-hands until this emergency patch goes out, and we keep the system offline while fixing it", this is definitely a 1.

Secondly, this barely counts as a security issue; some systems I worked on recently required error messages to tell the user how to fix the error they got. You don't simply say (for example) "attachment not found", you say "Field $FIELD is empty. This is a mandatory field" or similar.

There are still plenty of secure systems out there that will direct the user to create an account if an unregistered user attempts to log in.

It's a trade-off in usability: some places go the "Authentication failed (but we won't tell you why)" route, and others go the "Click here to sign up" route.

I get where you're coming from but I'm not sure if PDF generation was a goal for mdbook to begin with.
I'm pretty sure they're working on it now, but I'd stick to a domain specific tool, personally I find typst excellent to generate documents for prints.

For simple HTML docs mdbook is also excellent. I don't know if you could combine these two domains into one tool nicely. To me they're just too different.

although I have made presentations with mdbook using custom written preprocessors and a custom renderer (all of which were extremely crude, but did the job)

But that Commit-Id footer has no functional effect. I don't see how it would help me if I have a clone of the repo, and my upstream (in this case, the debian maintainer) rebases.

> Which you won't.

Why not? Doesn't it make sense to be able to track the history of what patches have been applied for a debian package?

Using transformers does not mutually exclude other tools in the sleeve.

What about DINOv2 and DINOv3, 1B and 7B, vision transformer models? This paper [1] suggests significant improvements over traditional YOLO-based object detection.

But even so, for a single user, the output rate for a very fast LLM would be like 100 tokens per second. With graphics, we're talking like 2 million pixels, 60 times a second; 120 million pixels per second for a standard high res screen. Big difference between 100 tokens vs 120 million pixels.

24 bit pixels gives 16 million possible colors... For tokens, it's probably enough to represent every word of the entire vocabulary of every major national language on earth combined.

> You have to shuffle your 800GB neural network in and out of memory

Do you really though? That seems more like a constraint imposed by graphics cards. A specialized AI chip would just keep the weights and all parameters in memory/hardware right where they are and update them in-situ. It seems a lot more efficient.

I think that it's because graphics cards have such high bandwidth that people decided to use this approach but it seems suboptimal.

But if we want to be optimal; then ideally, only the inputs and outputs would need to move in and out of the chip. This shuffling should be seen as an inefficiency; a tradeoff to get a certain kind of flexibility in the software stack... But you waste a huge amount of CPU cycles moving data between RAM, CPU cache and Graphics card memory.

Buy from listings with many sales and good reviews.

Look for reviews with real images and real seeming phrases in many languages, not 10 accounts all posting the same phrase with no pictures.

Buy from stores with a name, preferably who have established a "brand" for themselves across many products. UGreen are a great example of this for USB gadgets.

Don't buy from stores named Shop195772040, these will take your money and disappear or ship fakes. Don't buy suspiciously cheap items with no sales, these will do the same.

> In the entire history of civil nuclear power "unknown parties stole the radioisotopes" has never happened.

This reads a bit like "why do we need a QA department when we don't have any bugs"?

The reason nobody stole the stuff from reactors is because everyone has, by international law and also nonbinding recommendations, security and armed guards making sure they don't. These are not free.

The Goiânia accident was stupidity, not malice, so you can't predict how many people would die if it was done maliciously from how many were killed. My understanding is what keeps people (relatively) safe from this type of attack at the moment, is the public deployment of radiation sensors since 9/11, which we know about because of people with radioisotopes in them for medical reasons getting caught by them. These are not free.

The Chrenobyl reactors were housed in what’s "best described as a shed" because that was cheap. Same for all of the other design issues with those reactors: it made them cheap.

The rules that make reactors expensive are written in incidents.

> And only after that should we have cars. Cars should also be reserved for very heavy loads (more than 50kg), groups of people (not single drivers, 2+ people in the car), and various other niche uses.

I don't want to spend 6 hours commuting a daily in the UK. I've done this btw in the UK a decade ago. It was miserable.

It just isn't possible to commute in places without a car. Especially once you get outside of a main transit hubs.

Nah - given the ergonomics + economics, local coding models are not atm that viable. I like all things local even if just for safety of keeping healthy competitive ecosystem. And I can imagine really specialised uses cases where I run an 8B not-so-smart model to process oodles of data on my local 7900xtx or similar. Got older m2 mbp with 96gb (v)ram and try all things local that fit. Usually LMStudio for the speed add in MLX format models on ASI (as end point; plus chat for vibes test; LMStudio omission from the OP blog post makes me question the post), or llama.cpp for GGUF (llama.cpp is the OG; excellent and universal engine and format; recently got even better). Looking at how agents work - an agent smarts of Claude Code or Codex in using the tools feels like it's half its success (the other half the underlying LLM smarts). From the training on baked in 'Tool Use & Interleaved Thinking' on the right tools in a right way, to the trivial 'DONOTDO bad idea to fill your 100K useful context with random content of multi-MB file as prompt'. The $20/mo plans are insanely competitive. OpenaI is generous with Codex, and in addition to terminal that I mostly use, there is the VSCode addon as well as use in Cline or Roo. Cursor offers in-house model fast and good, insane economy reading large codebases, as well BYOK to latest-greatest LLMs afaik. Claude Code $20/mo is stingy with quotas, but can be supplement with Z.ai standing in - glm-4.7 as of yesterday (saw no difference glm-4.6 v.v. sonnet-4.5 already v.good). It's a 3 lines change to ~/.claude/settings.json to flip Z.ai-Anthropic back and forth at will (e.g. when paused on one to switch to the other). Have not tried the Cerebras high tok/s but wd love to - not waiting makes a ton of difference to productivity.

Usual social “sciences” ideological fantasies.

If you read the article, what does it mean “better mental health”? It means nothing, the “researchers” just came up with some made up metric that justifies their -probable- initial intended outcome according to their political ideology.

I couldn’t care less of the “mood” of people receiving my taxpayer money to stay home without finding a job. If I’m forced (by threat of violence from the state, mind you) to work more hours to give my money to these people, the minimum I expect, is for the metrics to show that my money, served to speed up these people finding a new job and stop living on my money.

All other metrics are irrelevant.

The sinking of the Moskva is better understood as a WWII-era lesson - if a warship has lots of munitions up top, unprotected by armor, then all an enemy needs to do is set the first few of those off. Even with an elite crew and ship full of damage control equipment, the ship may end up not worth repairing.

Example: Two 550 lbs. bombs came very close to sinking the USS Franklin - https://en.wikipedia.org/wiki/USS_Franklin_(CV-13)#19_March_... The Franklin was about 3 times the size of the Moskva.

Let’s call them bureaucrats, but let’s not forget that their baseline is to be public servants, while that of product managers is to increase profits :-) . I think the system is working as intended though, because increasing profits can be a great driver for innovation and service to the consumer, until it’s not and the “immune system” (the bureaucracy) must be called on to fight the uncontrolled pathological growth…

It seems to me the only adequate solution regarding any of these types of security and privacy vs data sharing and access matters, is going to be an OS and system level agent that can identify and question behaviors and data flows (AI firewall and packet inspection?), and configure systems in line with the user’s accepted level of risk and privacy.

It is already a major security and privacy risk for users to rely on the beneficence and competence of developers (let alone corporations and their constant shady practices/rug-pulls), as all the recent malware and large scale supply chain compromises have shown. I find the only acceptable solution would be to use AI to help users (and devs, for that matter) navigate and manage the exponential complexity of privacy and security.

For a practical example, imagine your iOS AI Agent notifying you that as you had requested, it is informing you that it adjusted the Facebook data sharing settings because the SOBs changed them to be more permissive again after the last update. It may even then suggest that since this is the 5685th shady incident by Facebook, that it may be time to adjust the position towards what to share on Facebook.

That could also extend to the subject story; where one’s agent blocks and warns of the behavior of a library an app uses, which is exfiltrating WhatsApp messages/data and sending it off device.

Ideally such malicious code will soon also be identified way sooner as AI agents can become code reviewers, QA, and even maintainers of open source packages/libraries, which would intercept such behaviors well before being made available; but ultimately, I believe it should all become a function of the user’s agent looking out for their best interests on the individual level. We simply cannot sustain “trust me, bro” security and privacy anymore…especially since as has been demonstrated quite clearly, you cannot trust anyone anymore in the west, whether due to deliberate or accidental actions, because the social compact has totally broken down… you’re on your own… just you and your army of AI agents in the matrix.

That's why you need to go to other regions, not remain in the same area. Putting all your eggs in one basket (single area) _is_ stupid. Having a single shutdown command for the whole cluster _is_ stupid. Still accepting writes when the system is in a degraded state _is_ stupid. Don't make it sound worse than it actually is just to prove your point.

70k goes a lot further in these places than 170k does in a high cost of living area that is for sure. And 70k jobs aren't so hard to find in these places if you are college educated. You can easily pull that in sales. In management. There are consulting offices in these places. Yes, some tech. Jobs where you can make a whole lot more than 70k. Healthcare. Law. Consulting. Real estate. Finance. Accounting. Yes even manufacturing is still present at a certain scale. There are still a few steel mills and these days they employ mostly high skilled engineers. Still a need for pretty much all disciplines of engineering in these places in various sectors.

People think all there is to do is work in a waffle house in the shadow of a closed steel mill, but really these are cities that by definition need a somewhat diversified economy to even function as a city at all. They have all the various pieces that make a city a city and a region a region. Sorry, not much startups, but that's about the only exception, truly, and may not even be the case adjacent to the state flagship universities.

Not tptacek, but my search yielded this which seems relevant (to the network monitoring tool once named Bro, now Zeek):

https://www.icir.org/mallman/pubs/APT07/APT07.pdf

> The “SH” state indicates that the remote peer sent a SYN followed by a FIN—however, the monitor never recorded a SYN-ACK from the local peer. At first glance, this would seem to indicate a scanner that is trying to make connection attempts look
as real as possible in the hopes of not triggering an alarm. However, such connections can also indicate a vantage point problem whereby the monitor is not observing outgoing traffic from some hosts. While in general the monitor placement at LBNL can observe both incoming and outgoing traffic, there were periods of time where the traffic for some LBNL hosts would partially bypass the monitor. From a measurement perspective this is clearly undesirable.

Mdbook passes a version and the renderer/preprocessor can/should do a version check. Since it uses semantic versioning I would expect it to abide by those rules.

There's some example code in their docs (fn handle_preprocessing in the no-op preprocessor) which I've actually included in a preprocessor I wrote some time ago.

I highly recommend setting up a kodi combo: real-debrid/fen/seren/coco scrapers/tmdb helper with your trakt account/arctic fuse 2 (netflix like skin). It is a complete "stream everything" netflix interface.

It takes quite a while to understand how to set everything up and needs tons of customization (which is also a positive), but reddit is your friend. For example this is a good guide (although bit dated, some info may be older but generally it still fits https://www.reddit.com/r/Addons4Kodi/comments/zzfdtb/allincl... )

I know people also use *arr stack and jellyfin to setup their own library but my problem is that i never /know/ what to watch. With this setup, i just turn it on, get to browse customized/recommended and random lists like in netflix and it streams directly via real-debrid or premiumize

Oh; if you decide to have a dedicated raspberry pi for this thing (so you can use it with tv easilly), use a regular raspbian os or something, do NOT use libreelec. It is trying to be heavily customized, but in the end is just worse, buggy, bad wifi support, slow releases from small team, and unability to manually update packages

Nagle himself says (or said 10y ago) that the real culprit is delayed ACK: https://news.ycombinator.com/item?id=10608356

I’m no expert by any means, but this makes sense to me. Plus, I can’t come up with many modern workloads where delayed ACK would result in significant improvement. That said, I feel the same about Nagle’s algorithm - if most packets are big, it seems to me that both features solve problems that hardly exist anymore.

Wouldn't the modern http-dominated best practice be to turn both off?
Show HN: SVG to WebP – bulk conversion that runs locally in the browser
by kuzej | 2025-12-23 09:03:40+00:00
Hi HN,

I built svgtowebp.org, a small “SVG to WebP” converter for the moments when you just want a quick, predictable export without uploading files.

The problem I kept running into was simple: I often get a folder of Scalable Vector Graphics (SVG) from designers, but the place I need to ship them wants a raster image, and WebP is a good format when you care about smaller files.

What this does:
- Convert SVG → WebP for a single file or a whole batch (drag and drop multiple files, then one click converts the whole queue).
- Control output settings: width, height, fit mode, quality, lossless toggle, background (including transparency), and DPI.
- Preview output and compare file sizes, then download individual results or “Download All” as a zip.

Privacy and speed:
Everything runs locally in your browser (no uploads), so your files never leave your device.

I would love feedback on edge cases (fonts, filters, very large SVGs), and on which settings you would want next.

No, but the models you will be able to run, will run fast and many of them are Good Enough(tm) for quite a lot of tasks already. I mostly use GPT-OSS-120B and glm-4.5-air currently, both easily fit and run incredibly fast, and the runners haven't even yet been fully optimized for Blackwell so time will tell how fast it can go.

Needless to say, Zawinski was more than a little frustrated with how the Debian maintainers do things.

But honestly, this took 30 seconds to Google and was highly publicized at the time. This whole "I never heard of this, link??" approach to defend a lost argument when the point made is easily verifiable serves to do nothing but detract from discussion. Which, you know, is what this place is for.

Yes, if you're doing what everyone else is doing you can just use tensor cores and libraries which optimize for that.

Contrarily if you're doing something that doesn't map that well to tensor cores you have a problem: every generation a larger portion of the die is devoted to low/mixed precision mma operations. Maybe FGPAs can find a niche that is underserved by current GPUs, but I doubt it. Writing a cuda/hip/kokkos kernel is just soo much cheaper and accessible than vhdl it's not even funny.

AMD needs to invest in that: Let me write a small FPGA kernel in line in a python script, compile it instantly and let me pipe numpy arrays into that (similar to cupy rawkernels). If that workflow works and let's me iterate fast, I could be convinced to get deeper into it.

The article does address that:

> Unfortunately, it’s not just delayed ACK2. Even without delayed ack and that stupid fixed timer, the behavior of Nagle’s algorithm probably isn’t what we want in distributed systems. A single in-datacenter RTT is typically around 500μs, then a couple of milliseconds between datacenters in the same region, and up to hundreds of milliseconds going around the globe. Given the vast amount of work a modern server can do in even a few hundred microseconds, delaying sending data for even one RTT isn’t clearly a win.
