@catsaladCat 🐈🥗 (D.Burch) :blobcatrainbow: Not exactly what you asked, but after I lived through the 2011 Virginia earthquake I learned something important. The old advice for surviving an earthquake was that you should take shelter in a door frame, as those are supposed to be structurally stronger than regular walls. But that old advice has been disproven. Experts now agree that you're much safer taking shelter under a table or desk.

I just wish I had heard this before the earthquake rather than after, because I feel like an idiot for spending it standing in a door frame

wait, why is a bit per second called a "baud"?

(looks it up)

...huh, so apparently the word "baud" is even older than computers, it was named after émile baudot, who invented a system of coding characters for the telegraph (which actually looks more like a predecessor to something like ASCII, and apparently also is the origin of CR and LF as separate symbols!)

Three bugs appear.

“Ah, with my senior software developer senses I detect these are in fact not three separate bugs, but a single bug manifesting in different ways. A greener developer would have fallen into this trap and spent all day chasing shadows!”

*7 hours of struggling*

They are three separate bugs.

TIL car tyre sizes (eg, 225/55R17) manage to combine metric (225mm width), a percentage for an aspect ratio (55%), and imperial (17 inch diameter). I think that’s just marvellous. Well done everyone.

Americans!

If the massive number of internet censorship bills already introduced wasn't enough, Lindsey Graham, along with a handful of co-sponsers (Durbin, Blumenthal, Whitehouse, Klobucher, and Hawley), intends to reintroduce his bill to sunset Section 230 next week.

Section 230 is what allows many websites to exist at all. If this bill passes, many smaller websites will be forced to shut down, and mainstream platforms will either abandon moderation altogether or remove anything even vaguely controversial to avoid lawsuits.

Regular people would be unable to post on sites that take the latter approach (acting as publishers) and would have their voices drowned out by scams and hate speech on sites that take former approach (abandon moderation entirely).

Getting rid of Section 230 would not result in more free speech, it would not "hold Big Tech accountable," or whatever else people like Graham and these co-sponsers say repealing Section 230 would accomplish.

Please call your Senators and Representatives!

The internet is best when knowledge is shared openly. This is why this legendary ramen ebook on google docs is still a towering achievement. I think it has been directly responsible for good ramen existing in some places that didn't have good ramen for a very long time

Ich kann dieses Gerede von wegen "Brandmauer ist undemokratisch" wirklich nicht mehr hören. Jede Partei ist frei zu entscheiden, mit welchen anderen Parteien sie koalieren, zusammen abstimmen oder sonstwas tun möchte – oder eben nicht. Diese Freiheit ist eben auch Teil der Demokratie. Wenn nun eine Partei regelmäßig abfällig über demokratische Institutionen spricht , andere als "Systemparteien" verunglimpft & als "Feind" markiert, wäre es doch absurd, sie als natürlichen Verbündeten zu sehen.

A year and a half ago, i opened my nginx logs to discover that tens of thousands of individual IPs had started fetching random pages in my git forge. Today, i have mostly beaten these bots and confined them to a torture room where they are endlessly fed garbage, thanks to Iocaine.

This is a post about what worked, what did not, some numbers, and the cost (technical, financial, human) of giant tech companies scraping all of our small services for LLM training.

I see a lot of blank, outright rejection of , LLMs general or coding LLMs like in special here on the Fediverse.
Often, the actual impact of the AI / in use is not even understood by those criticizing it, at times leading to tantrums about AI where there is....no AI involved.

The technology (LLM et al) in itself is not likely to go away for a few more years. The smaller variations that aren't being yapped about as much are going to remain here as they have been for the past decades.
I assume that what will indeed happen is a move from centralized cloud models to on-prem hardware as the hardware becomes more powerful and the models more efficient. Think migration from the large mainframes to the desktop PCs. We're seeing a start of this with devices such as the ASUS Ascent / .

Imagine having the power of under your desk, powered for free by cells on your roof with some nice solar powered AC to go with it.

Would it not be wise to accept the reality of the existence of this technology and find out how this can be used in a good way that would improve lives? And how smart, small regulation can be built and enforced that balances innovation and risks to get closer to (tm)?

Low-key reminds me of the Maschinenstürmer of past times...

It's built on top of my C++ Standard -> markdown tool github.com/lefticus/cppstdmd

and my C++ Evolution viewing tool cppevo.dev

healthcare ai

Like imagine going to your gp for knee pain that gets worse after exercise with no obvious point of injury and having them ask no further questions, do no physical exam, and order xrays.

In fact, imagine having a GP who refuses to touch you at all, even when explicitly asked by other physicians to do things like remove stitches or check iud placement.

re: healthcare ai

Anyway, you can plug the exact schpiel I gave to my doctors into an ai chatbot and it will spit out my correct diagnoses along with 2-3 other possibilities and the questions/tests to discriminate among them (which are correct!)

I have three primary things wrong with me: one affects 20% of women, one affects 1% of people, and the other affects 10% of women. I had pretty textbook and moderate-severe presentations. The first took a decade to diagnose, the second two decades, and the third three. And I sure didn't get adequate treatment right away after diagnosis either.

If doctors want people to trust them over something that regurgitates their textbooks mixed with random patient forum advice, maybe they should read their goddamn textbooks and pay attention to the lived experience of their patients.

I'm building an online collection, in the hope of preserving all those handy help files we used to work with back in the days. Can you help?

blog.davep.org/2025/12/12/nort

A Norton Guide collection

As I've mentioned a few times on this blog, I've long had a bit of a thing for writing tools for reading the content of Norton Guide files. I first used Norton Guides back in the early 1990s thanks to the release of Clipper 5, and later on in that decade I wrote my first couple of tools to turn guides into HTML (and also write a Windows-based reader, then rewrote it, wrote one for OS/2, wrote one for GNU/Linux, and so on). One tool (ng2html) got used by a few sites on the 'net to publish all sorts of guides, but it's not something I ever got into doing myself. Amusingly, from time to time, because I had a credit on those sites as the author of the conversion tool, I'd get random emails from people hoping I could help them with the topic of whatever guide they'd been reading. Sometimes I could help, often not. From what I've recently been told two of the biggest sites for this sort of thing (they might even have been the same site, or one a copy of the other, I didn't really dive into them too much and wasn't sure who was behind them anyway) have long since gone offline. This means that, as far as I can tell, a huge collection of knowledge from the DOS days is a lot harder to get to, if it hasn't disappeared altogether. This makes me kind of sad. So I had an idea: having recently polished up my replacement for ng2html, why not use that to build my own site that publishes the guides I have? So I set about it. There's one wrinkle to this though. While the other sites seemed to just publish every NG file they got their hands on, I'd prefer to try and do it like this: publish every guide I have in my collection that I have a licence or permission to publish; or as near as possible1 Given all of this, norton-guides.davep.dev has been born. The repository that drives it is on GitHub, and I have a wiki page that lists all the guides I have that I could possibly publish, showing what I know about the copyright/licence of each one and what the publishing state is. So with this, I'm putting out a call for help: if you remember the days of Norton Guide help files, if you have Norton Guide help files I don't have, and especially if you are the copyright-holder of any of these files and you can extend me the permission to open them up, or if you know the right people and can get me in touch with them, DROP ME A LINE! I'd also love to have others join me in this... quest. So if you want to contribute to the repository and help build it up I'd also love to hear from you. I will possibly be a little permissive when it comes to things that I believe contain public domain information to start with. ↩

올해 여름에 어느 대기업 계열사에서 입사 제의가 들어와서, 아예 내 이름이 출제지에 박혀있는 특제 코딩 테스트까지 만점으로 깔끔하게 통과하고 면접도 봤다.

면접도 얼추 잘 끝나긴했는데 갑자기 내부 사정상 신규 채용을 못하게되서 미안하단다.

그리고 올해 11월인가 그 팀이 사실상 해체 수순을 밟고있다는 소식이 언론을 통해 들려왔다.

고용승계도 안된다던데 연봉 올려보려다 큰일날뻔 했음.

Curious about what a modern alternative to SwiftData looks like?

• Value types instead of reference types
• Full access to SQL
• Works everywhere (SwiftUI, UIKit, AppKit, ...)
• iCloud sync and sharing
• Type-safe & schema-safe tools

Well…
pointfree.co/collections/tours

Tours › Tour of SQLiteData

[SQLiteData] is our alternative to SwiftData. It's built on top of the battle-tested SQLite database, gives you full access to everything SQL has to offer, allows you to embrace all of Swift's most powerful domain modeling tools, such as structs and enums, and even allows you to sync your user's data across all of their devices and share records with other iCloud users for collaboration. Join us for a tour of the library where we build a moderately complex app from scratch to show off many of the library's features. [SQLiteData]: https://github.com/pointfreeco/sqlite-data
