> password logins enabled

Disabling sshd password logins is security 101, and the default for some cloud provided images these days. If password logins haven't been disabled, what other doors have been left open anyway?

alexchamberlain··on I refuse to accept a censored Internet. Join Me at FOSDEM 27
> gives dumb people access to each other

Was this a serious comment? It made me realise that prior to the Internet, information flow was controlled by journalists or through peer reviewed papers and academic forums. People without advanced education would, generally, be limited to people in their local area.

alexchamberlain··on UUIDv7 doesn't have the properties you think it does
The author is in DevSecOps (i understand the Sec part...) - nitpicking is in the job description.
alexchamberlain··on I designed a nose guard for my dog and gave it away. Now 500 dogs wear one
Wasn't part of the point of the post was that this is a passion project? It's not a viable business.
alexchamberlain··on Apple HomeView
Isn't this "just" the latest iteration of a coprocessor?
alexchamberlain··on Claude Haiku 5.5
Isn't it less than a year since Claude models went from 100k token limit to 1M limit? Don't get me wrong - my main agent normally gets to 25% or so before I clear it these days, but as a subagent, doing research or summarisation, I don't think 100k is "absurdly low".
alexchamberlain··on I tested 10 model/harness combinations on the same Three.js task
Am I missing something or does sorting by Duration not work? Chrome on Android mobile
alexchamberlain··on Statichost.eu – European static site hosting
No? This company is based in Sweden, right?

That being said, the only reference to the EU is the domain itself - everything else says European, and the UK didn't move during Brexit.

alexchamberlain··on Screen viewing time from age 1 to 8 years and subsequent academic performance
Given the negative social perception of screen time, wouldn't the parents be motivated to report lower than actual numbers? Furthermore, this is one population (Singapore) and doesn't detail (at least not in the summary) how screen time varied from day to day (eg my children have substantially less screen time on school days, than weekends. Screen time in both cases tends to be biased towards breakfast time, when the house is a bit manic, or after significant periods of outdoor/energetic activity when everyone needs a rest.)
alexchamberlain··on England set to be one of the first countries to eliminate hepatitis C
I don't think so. My understanding was "confirmed" by ChatGPT, though I haven't looked at the sources.

> Rugby in Ireland is governed by the Irish Rugby Football Union (IRFU), which was established in 1879, decades before Ireland was partitioned in 1921. It has always organised rugby on an all-Ireland basis.

alexchamberlain··on England set to be one of the first countries to eliminate hepatitis C
And, of course, the Ireland rugby team picks players from both the Republic of Ireland & Northern Ireland.
alexchamberlain··on An ESP32 based plane radar for my desk
OTA = over the air. ie online updates you’d expect of a more polished product
alexchamberlain··on I think Anthropic and OpenAI have found product-market fit
I think you should highlight your exemplary pre-AI writing too.
alexchamberlain··on Where are all the UK red telephone kiosks?
https://www.kcom.com/about-us/history/ they were operated by a separate company, so the crown wasn't appropriate.
alexchamberlain··on Async Rust never left the MVP state
It seems like inlining futures that aren't holding variables over the await point might solve a large part of these issues?
alexchamberlain··on Open Source Endowment – new funding source for open source maintainers
> Government support won't work for OSS at scale — it's too globally decentralized... We recently received US 501(c)(3) tax-exempt charity status.

If this is successful in the first iteration, I'd love to see a UK and EU based charities too. That would allow european donors to support on a gross pay basis, and may simplify grants to european nationals too. (I'm sure similar things apply in other jurisdictions too.)

alexchamberlain··on We installed a single turnstile to feel secure
I'm not going to comment on the security implications of either situation, but is there a companion piece by the facilities team complaining about the amount of paperwork required to install turnstiles only for a software engineer to come along and lock them out of Jira on a whim?
alexchamberlain··on Show HN: Mines.fyi – all the mines in the US in a leaflet visualization
There are 3 mines on Manhattan; is that correct?
alexchamberlain··on MessageFormat: Unicode standard for localizable message strings
Apologies if this is obvious and I missed it. Does this define a way to store the strings in various languages?
alexchamberlain··on Kitchen optimizations
You can have 240V outlets too... at least, a lot of woodworkers seem to install them in their garages. Are they legal in the kitchen?
alexchamberlain··on CO2 batteries that store grid energy take off globally
Would this be effective at smaller volumes? Could it get down to say the size of a washing machine for use at home?
alexchamberlain··on Karpathy on DeepSeek-OCR paper: Are pixels better inputs to LLMs than text?
Thanks, that's really interesting. Do they correct for spelling mistakes or internationalised spellings? For example, does `colour` and `color` end up in the same token stream?
alexchamberlain··on Karpathy on DeepSeek-OCR paper: Are pixels better inputs to LLMs than text?
I'm probably one of the least educated software engineers on LLMs, so apologies if this is a very naive question. Has anyone done any research into just using words as the tokens rather than (if I understand it correctly) 2-3 characters? I understand there would be limitations with this approach, but maybe the models would be smaller overall?
alexchamberlain··on Show HN: SQLite Online – 11 years of solo development, 11K daily users
My point was more about the original comment is fine from the perspective of an American, but for the rest of the world, it doesn’t really matter if it is USD or rubles - it’s still a foreign transaction. I appreciate that for a large percentage of the world, consumers can probably do an approximation of the USD conversion in their head, and not a rubles one, and therefore, USD may be more friendly. That being said, the sales page has already got the approximation in USD anyway, which would be enough for me.
alexchamberlain··on Show HN: SQLite Online – 11 years of solo development, 11K daily users
> charging in rubles is most probably confusing, and that a flat $10 usd/month would be easier

As a Brit, I'd rather GBP...

Isn't this comment a form of US defaultism?

alexchamberlain··on EU age verification app not planning desktop support
But what if my battery runs out?
alexchamberlain··on Git: Introduce Rust and announce it will become mandatory in the build system
The developers of git will continue to be motivated to contribute to it. (This isn’t specific to Rust, but rather the technical choices of OSS probably aren’t generally putting the user at the top of the priority list.)
alexchamberlain··on Grapevine canes can be converted into plastic-like material that will decompose
This is the problem though, right? It’s not one league table of environmental goodness - there are tradeoffs that as an educated consumer are impose to navigate.
alexchamberlain··on Grapevine canes can be converted into plastic-like material that will decompose
I think banning plastic completely in packaging is a much harder ask, as whether it is needed is rather nuanced (if I understand it correctly). For example, it's perfectly possible to deliver cucumbers to an end customer without them being shrinkwrapped. However, to deliver enough cucumbers to enough customers for a supermarket scale, I understand from several documentaries that plastic is still required in that case. (For those outside the UK, plastic covered cucumber is the social barometer for plastic packaging.) Banning plastic bags was easy and simple, and our laws don't tend to deal with nuance very well...
alexchamberlain··on Grapevine canes can be converted into plastic-like material that will decompose
The UK banned single use plastic bags at major supermarkets. We all moaned about it for a few minutes, forgot our reusable bags a couple of times and then got on with it. Even the small plastic bags you put fruit or pastries in are now gone in a few super markets - initially, they replaced them with transparent paper-based windowed bags, but then I think people realised you really don't need to see inside the bag, and brown paper bags are back.
