alex_duf··on Mistral's Shieldstral: 3B open-weights model for multimodal moderation
could the long s `ſ` be throwing the model off?

I wonder to what degree malice can be engineered to look like incompetence?

alex_duf··on Microsoft has released software updates to plug at least 570 security holes
While I do think it's wise for people to start looking at alternatives, I don't think this specific news should sway one way or another.

Windows (like Linux or macos) contains an enormous amount of code, and with large code-bases you're certain to have security issues.

Finding these security issues and fixing them seems like a good idea, no matter how much you love or hate Windows.

alex_duf··on Postgres rewritten in Rust, now passing 100% of the Postgres regression tests
I think this shouldn't be taken too seriously, from what I understand it's an exploration of what's possible with today's LLMs.

You're right to talk about the trend though, because what it shows is how the cost of re-writing well covered project has completely crashed, so that in itself is a learning.

alex_duf··on US Grid Constraints: Towards 40GW+ of Behind-the-Meter Datacenter by 2028?
Economic development is great and I'm all for it, but it shouldn't be done at any cost. I quite like our atmosphere, ideally with less than 400ppm of CO2. We're finally seeing signs of economic development decoupling from primary energy consumption, there are positive signs.

I find that it's just a shame to be so close to energy abundance - through renewables - to only be set back by the installation of "temporary" gas turbines. The economic incentive is so great that delaying the datacenters in order to power them cleanly isn't even considered: there's no incentive to do so. This may sound a little alarmist, but if it's GW of capacity in 2028, it's TW in the mid 30s.

I'd much rather live in a heavily compute-constrained world for the next 5 years or so than in a world that keeps increasing its gas consumption.

There's just no way to force our incentive to align with preserving our climate, and it's making me extremely depressed.

By your logic we shouldn't question any development, at any cost, including if it contributes to making our world uninhabitable for billions of people within our life's timescale?

alex_duf··on US Grid Constraints: Towards 40GW+ of Behind-the-Meter Datacenter by 2028?
I'm hoping the kind of gas turbines being installed on these datacenters are capable of quickly responding to a load change, meaning the primary source of energy could be solar during the day and complement when there isn't enough energy.

But I haven't looked into where these datacenter are being placed, I'm assuming that although solar is cheap now, the surface needed would make the purchase of nearby land probably not worth it. These new categories of datacenters are becoming very energy dense...

alex_duf··on Meta forced engineers into AI training. Now it's giving some a way out
definitely, and I'm glad there are company that do! but they only exist because they have an incentive to do so: a crowd ready to pay for it.

It's surprising but it's a real thing: https://en.wikipedia.org/wiki/Martian_meteorite
alex_duf··on US Grid Constraints: Towards 40GW+ of Behind-the-Meter Datacenter by 2028?
What an absolute ecological disaster. If bubble there is, now would be a great time for it to pop.
alex_duf··on Meta forced engineers into AI training. Now it's giving some a way out
I think this is a misconception of how businesses are working. Maybe one person Vs another would yield a slightly different trajectory, but fundamentally, if you want to see why a leader takes X or Y decision, you have to look at what are the incentives.

Meta has a lot of personal data, what are the incentives? Selling it, use it to train AI, sell products to capture more data.

alex_duf··on An Introduction to YOLO26
I'm sure the model is capable, but I find it funny that the sample image that contains three bears gets detected as two elephants.
alex_duf··on Investors get real-time view of UK bond market activity for the first time
>I hope I don’t sound too selfish but I am a USA citizen

The rest of the world is getting tired of worrying about the US's economical situation, whether it the dotcom bubble, the sub-primes, or now the potential AI bubble.

So apologies for being blunt here, but yes it does sound selfish to me

alex_duf··on Identity verification on Claude
Ha that's a good point I didn't realise the process was pre-dating the whole fable 5 story
alex_duf··on Identity verification on Claude
It's about covering their arse before reopening Fable 5

They don't care if anyone is using a fake ID, they care that they can send the hot potato back to the American government. That gives them a legitimate "not my fault if people can make fake ids. In fact it's your fault"

alex_duf··on Malware developers added nuclear and biological weapons text to to their spyware
It still lowers the bar to have an interactive encyclopedia that can diagnose your issue at hand. Maybe you can divide your team by two, or reduce your development time.
alex_duf··on New method turns ocean water into drinking water, without waste
Obviously this is region specific, but slowing down water is one of the best ways to have fresh water.

Slow it down from trickling down a slope and you have two things: more vegetation (which also retains water) and more time for that water to penetrate the ground for local wells.

You can completely "terraform" a desertic region https://youtube.com/shorts/cfhbtgon4Nk?is=oAExB5UeMAsShBux

alex_duf··on Tracing a powerful GNSS interference source over Europe
Repeatedly, over years, only for 2 to 5 seconds at a time? Seems unlikely
alex_duf··on He Blew the Whistle on DOGE. Then His Brakes Were Cut
Yeah there's been some debate about it in the news, because only a certified device can approve it, meaning this takes away any open-source platform to prove you're a human
alex_duf··on Claude Opus 4.8
It's funny that we've reached the level where LLMs draw more correct bikes than any random person
alex_duf··on I'm Tired of Talking to AI
With AI we're about to have a trust crisis (I'll explain in a sec), so if we extrapolate it very far, we could see a world where nobody trusts anything displayed on a device, which is essentially what you describe but in a world with electricity still running.

The trust issue: we already see hacker news members accusing each other of being LLMs, we already see legitimate images being immediately put in the AI category, and AI images and videos being shared as if the truth. We already see signs of infosec changing forever, with flaws found in SSL libraries that makes you wonder how trusty that little padlock next to the URL will become, we already see operating systems having to patch faster than they can.

With all that you get to wonder how much you can trust the pixels you see on your device, and how much we'll collectively trust them in the future. That leads you to trust your neighbours way more than your social media feed, which frankly, may have a positive impact on society over the long run, despite a very painful transition.

That's under the hypothesis that AI leads us to experience a trust crisis, which isn't a given.

alex_duf··on Anthropic is expanding to Colossus2. Will use GB200
It's the low frequencies that's more of an issue apparently. Benn Jordan has a great series of videos about it, including one on Colossus
alex_duf··on Citroën metropolis concept car (2010)
Not sure about that, the mid 90 to early 2000s have been really poorly looking in my opinion

Electric Light Orchestra anyone?
alex_duf··on First tunnel element of the Fehmarnbelt Tunnel immersed
Agreed, I got carried away
alex_duf··on Google Cloud Fraud Defence is just WEI repackaged
I'm seeing this stance a lot "this is obviously AI generated"

Why? What's LLM generated? How can you tell?

To me what's obvious is that our trust system is already breaking down. Commenters accusing each other of being AIs is also another example of this.

alex_duf··on Dirtyfrag: Universal Linux LPE
there's an argument to be made that new code will be inspected before being merged and therefore the classes of bugs an LLM is likely to find will not be merged until it's fixed.
alex_duf··on Alaska megatsunami was second largest ever recorded
Goodness me, 524m for the tallest tsunami is absolutely nuts
alex_duf··on OpenTrafficMap
Rotterdam is using rain data to asjust traffic lights. Bicycles are waiting less at intersections. They also make the amber light longer to give you time to break for farther away and avoid a fall.
