grumbelbart2··on Supermarket freezers across Europe hit by second suspected cyber-attack
All of this can be done without connecting edge devices directly to the internet (and potentially allowing inbound connections). The question is not why they have networking, but why the connectivity is such that an attack like this is even possible.
grumbelbart2··on Iterating Backwards in C
> True. But I think "int" would be the right choice anyway in almost all case.

It's the worst choice. int is 32-bit on most 64-bit architecture/compiler-versions that matter.

grumbelbart2··on GitLab Security Incident: Attempted Exploitation of CVE-2026-97229
Which options are there, really? There is re-write, fixing, and mitigation.

We have a lot of legacy code that probably contains many bugs that could be exploited.

We could either stop using that legacy code, i.e. re-write and move to a newer library / package. Or fix the old code.

I now believe that "fixing" the code is actually in reach for an organization such as Google, which has deep pockets, frontier AI models, and a history of working on open source. Spend a few billions to walk through every package that runs on a common Linux installation, find potential issues and robustify the code.

grumbelbart2··on The US added a record 20.2 GWh of battery storage in just 3 months
Mostly because we already used all suitable places. It also has a huge environmental impact, large upfront costs that you can only spend in bulk, permissions, lawsuits, protests from the local population and so forth.
grumbelbart2··on Solar power is becoming bigger than nuclear
> Fixing this issue would require new remotely-operated breakers to be installed, which is costly, and it's hard to justify installing them proactively just in case.

No, the fix for this issue is that the inverter of your local solar installation checks if the grid delivers a 50 or 60 Hz waveform, and breaks if it does not. This is pretty much the standard in any installation today, and it's mandatory whether you declare your installation or not.

Side note, there is recently a push to vary the allowed deviation from 50/60 Hz a bit for each installation. The risk is that if all installations stop delivering at, say 50.1 Hz, then if the grid exceeds that value for some reason, there would be a very sudden drop in supply since all solar installations shut off at the same time.

Some say water is never wet, it makes wet.

How would a single agent work that long, the context window would overflow pretty quickly, no?
grumbelbart2··on A 10-year-old CNN outperforms frontier LLMs for skin cancer diagnosis
It's mostly a scale thing. Transformers scale better when you have a lot of training data. (Not saying CNNs don't scale, but it's way more difficult to tune the hyper parameters).

For smaller training data sizes, transformers don't have a clear advantage over CNNs. CNNs are still the way to go if you have problems that are not too complex, and especially constraints regarding inference costs. Think of a small edge device / sensor that counts apples in your apple picking machine.

What we sometimes see is that a backbone is trained using transformers, then a smaller CNN is destilled from that (DinoV3 for example).

grumbelbart2··on No signs of AI payoff outside the tech sector
And by buying all of the available compute.
grumbelbart2··on Solar surpasses nuclear power globally for first time
Uranium, Plutonium were created by fusion processes as well. Fission extracts energy put there by the fusion inside a dying star.
grumbelbart2··on New 'super ice' 10 times stronger, bringing it close to the strength of concrete
But those fibers disturb the crystal lattice of the ice, so surely there is some tradeoff?
grumbelbart2··on An Apology
It's also other devices. I used to get a notification that my wife's AirPods would be following me. It only got silenced when we formed an Apple family.
grumbelbart2··on AlphaNIST
I know you are joking, but that is absolutely a possible trajectory. Reliable and cheap LLMs could lead to software that re-implements everything, instead of using libraries.
grumbelbart2··on How big is a Git commit?
Did you do —apparent-size?
grumbelbart2··on 4-hour battery storage is cheaper to install than gas turbines all across globe
Battery tech and production methods are still evolving and improving way faster than turbine tech and production. Meaning this is more than just production capacity.
grumbelbart2··on Backups Aren't Simple
> 99% of people don't backup

This depends on your viewpoint. Using gmail for example is an implicit backup of your e-mails. Uploading your pictures to Facebook the same. The move from local, private compute and storage to the cloud solved this issue for many to a degree that it is now less important.

grumbelbart2··on EU chief opens door for Canada to become 'associate member'
Cameron wanted to split the four freedoms. Canada does not, from what I can read.
grumbelbart2··on An update on Wayback Machine access
Google's scraper bot at least used to be behind IPs that you could identify via reverse-then-forward DNS. Not sure if that is still up to date, though.

grumbelbart2··on Muse – Meta’s personal AI agent
Remember when their Android app would open a local TCP port, and they would have websites connect to localhost:PORT so they could deanonymize you? That was only like 1 year ago.
grumbelbart2··on Three sites made 215,128 “best software” pages for AI. Perplexity cites them
Sure maybe, but the online ad market is USD 400b give or take, which vastly outmatches any such budgets.
grumbelbart2··on Salad Theory
Few human concepts have strict, definable "boundaries". Things might seem obvious at first ("I know it when I see it", as stated by the US supreme court). You can take a concept, move its seemingly obvious properties into the extreme, and observe how the boundaries become blurry.

What is a car? Four wheels? What if you move two of those wheels closer together until they almost merge into one. What is a country? etc.

grumbelbart2··on The Einstein-Szilard Refrigerator (2020)
From what I know it's better for the life span. Less load, fewer start-stop cycles, less vibration.
grumbelbart2··on Anthropic's best AI model struggles to attract users as cheaper tools thrive
Once a thief, always a thief. I would not trust them to not have the communications buried deep in some log files in cold storage, to be digested when suitable.
grumbelbart2··on Geolocating a random island using geometry and CUDA programming
Memory on the first cruise missiles was so sacred though that they it could only store the pre-planned flight terrain data. So they not only loaded target coordinates, but full flight plans and had to launch from the programmed position. Desert was difficult as it has too few features.
grumbelbart2··on MicroGPT-C in pure C hits 10M TPS on Apple M5
That is my understanding as well. Thousands of monkeys do not equal or surpass a man, intellectually, even if working together. There is some intrinsic super linear scaling in intelligence.
grumbelbart2··on Using the railway network as a flatbed scanner
Railway operators do this to inspect tracks: Mount a line-scan camera that looks down, get an "infinite" image of the tracks, inspect for anything interesting.
grumbelbart2··on Red queen hypothesis – A new way forward for self-improving AI
I by no means wanted to suggest the opposite (that's how I found the connection)!

Schmidthuber is famous for his groundbreaking work in machine learning, but also for being somewhat left out when people list the "Grandparents of Deep Learning" and for being vocal about that. I just wanted to poke that bit. If your work takes off, it would be a great chance for him to shine.

grumbelbart2··on Red queen hypothesis – A new way forward for self-improving AI
Funnily enough, Jürgen Schmidthuber invented / coined the term "Gödel Maschine" in 2003: https://arxiv.org/abs/cs/0309048

He'll probably have a field day over this.

grumbelbart2··on Can I use my Outputs to train an AI model?
Of course it exists in Germany. If I say ‚Hello‘, I could not claim copyright on that sentence because it does not have the required schöpferische Höhe (threshold of originality). The sentence is simply not copyrightable, putting it into public domain.

Note that this is different from Gemeinfreiheit, where a copyrighted work essentially becomes public domain 70 years after the death of its creator.

grumbelbart2··on Can I use my Outputs to train an AI model?
Compiler output is a derivated work of the source code and thus keeps the copyright of the code.
