RachelF··on Leak Exposes 41,000 Homeland Security Workers–Including Undercover ICE Agents
Both are true, it is a single point of failure and a single point of convenience.

What always puzzles me about this stuff and critical infrastructure like nuclear powerplants, is why is an internal network connected to the public Internet at all?

If you have to connect it to the Internet, then why is it talking to unknown devices?

RachelF··on The 'else' keyword is probably a literal translation from German (2020)
someone else ;-)
RachelF··on Radio-tagged Monarch butterflies
Thank you - the tracker they use weighs in at 60 milligrams, incredibly light.
RachelF··on Broccoli2Shell: Brotli decoder RCE in Node.js, Python and more
Pretty much everything that talks http has this Brotli library linked in. A quick file search on a Windows dev box showed:

- git

- Sublime text

- VS studio

- CUDA

- .NET

- inkscape

- AzureTools

RachelF··on GPU-unlock: FP/BF16 instruction issue rate on Nvidia 3000's cards
There's also a Windows version:

RachelF··on GPU-unlock: FP/BF16 instruction issue rate on Nvidia 3000's cards
A semi related: a patch for those with multiple cards. You can unlock around 20% increased card to card speed on consumer GPUs using this library:

https://github.com/aikitoria/open-gpu-kernel-modules

The hardware supports it, but then Nvidia disabled it if the driver detects cheaper cards. This bypasses the NVidia slowdown.

RachelF··on mitmproxy adds --emudhra option
Three bits of trust now - the number 4: https://www.theregister.com/security/2026/10/20/indian-certi...
RachelF··on Reverse engineer anything with agents, from app behavior down to native binaries
It will be interesting to see if anyone reverse engineers IDA Pro!
RachelF··on Telegram Desktop vulnerability allowed any user's file to be stolen
It looks very bad that Telegram took almost 3 months to fix this vulnerability.

Reported 25 June

Fixed 16 September

I wonder why it took them so long?

RachelF··on Data Center Darling's $30B IPO Dream Crushed in 48 Hours
There's more to this story than non-existent data centers.

The executive team is rather rotten, too. One of them, Oliver Curtis, having recently spent time in jail for insider trading.

RachelF··on Lobbying
Lots of big lobbying companies corrupting Australia, too.

Less "sophisticated" countries just tend cut out the lobbyist middleman and call it what it is - bribery.

RachelF··on AnyPS5: Port PS5 binaries to PC without emulation (87% system libraries mapped)
There is not much goodwill in the world left towards Sony. They have screwed their customers over repeatedly (removal of PS3 Linux, PC spyware, removal of physical disks, banning arbitrary users online etc.), which makes the moral case for Sony piracy more ambiguous.
RachelF··on Using Blu-ray M-Disk as backup of last resort
Hard drives are way bigger, but M-Disk is more reliable for very long term storage.
RachelF··on Run Qwen 3.8 Flash Next (125B) on consumer hardware (RTX 4090) at 100T/s
This is true, progress has stopped on the RAM and VRAM front.

Many new laptops come with 8GB as standard, the same as 12 years ago.

My 1060 from 2016 has 6GB of VRAM. A 5060 from 2025 has 8GB.

RachelF··on Gemini 4 Argon
And the anti-psychotic drugs Google feeds Gemini makes it hallucinate badly.

The US companies still have trillion dollar valuations like there is a monopoly. There just isn't one. They are all within a few percent of each other on the benchmarks.

The slightly lower Chinese open models are good enough for almost everything, too, and much cheaper. Like with humans there is plenty of employment for people with below genius level IQ's.

RachelF··on As A.I. makes law firms more efficient, clients ask: 'Where's my discount?'
Australia already has AI tax judgements:

RachelF··on SNL Weekend Update: Anthropic CEO Dario Amodei on A.I.'S Threat to Humanity [video]
Or George Carlin - perhaps it's just me, but modern shows aren't that funny anymore.
RachelF··on There are no "rogue" AI agents
> no one is getting arrested

An as individual or small company director, you would get arrested.

If you have billions of dollars to pay for lawyers and have political influence, you are above the law.

RachelF··on Rebuilding a 1995 GPS Time Server so I don't get Telstra'd
This is not a great idea. Pre-2000 GPS time server firmwares do no handle leap seconds properly.
RachelF··on A practical guide to running 8x RTX PRO 6000's
For those who can't afford RTX 6000's you can unlock around 20% increased card to card speed on consumer GPUs using this library:

https://github.com/aikitoria/open-gpu-kernel-modules

The hardware supports it, but Nvidia disabled it if the driver detects cheaper cards.

RachelF··on True Rate of Unemployment
Similar statistics for Australia: https://www.roymorgan.com/findings/10192-australian-unemploy...

It all depends on the definition of "Unemployment". Most governments do not count you as unemployed if you've stopped looking for work, been unemployed for over 6 months, or if you made $25 as an Uber driver for 1 hour's work that month.

RachelF··on How accurate have Ed Zitron's AI skeptic predictions been?
Very true. The problem is mainstream business media hasn't asked the questions that Zitron has.

So, much like current US politics, we're left with hype on both sides. That's all that gets the clicks/attention, and little balanced analysis in the middle.

RachelF··on How accurate have Ed Zitron's AI skeptic predictions been?
The fact is there is BullSh_t and hype on both sides.

Both Zitron and AI execs have good points, but both are trying to sell you something. The murky truth lies between the two extremes.

IMHO, having Zitron around is a counter to the AI leaders. Is he the best? No. Is he the loudest? Yes.

RachelF··on Evidence of Fraud in an Influential Study About Procrastination
Dan Ariely's fraud is pretty widespread.

He sold his research to an insurance company, who should have known better: https://www.lemonade.com/blog/oh-behave/

RachelF··on Show HN: We built the smallest dual-band aircraft tracker
Looks good. However, an RF question: Both CC1314 and LR2021 are sub 1GHz components, are you not working outside their spec at 1.090GHz?
RachelF··on Sleepwalker: Passive Backdoor with Its Own Command Language
This thing has been in the wild since 2024, so it had a good run.

It looks pretty bespoke, so there are likely other variants.

Also targeting the anti-virus executable is a smart way to hide. I don't think this backdoor was cheap to develop.

RachelF··on Nvidia agrees to acquire Hugging Face for $13B
Yes, this is ironic - it was the tinkerers using CUDA on cheap graphics cards that made Nvidia stuff useful in constrained academic environments.

True about Intel and ECC, but AMD now does similar things, even with their consumer CPUs and chipsets.

These three companies now make very sure that consumer products can never canibalize those juicy data center profits - so they make sure to limit what the consumer segment can do.

RachelF··on Nvidia agrees to acquire Hugging Face for $13B
I guess we may have to start paying to download models.

Or perhaps they will start throttling downloads for free users.

I don't know what they business case is, it might be to shut them down: I suspect good free models on local hardware is a threat to Nvidia's investments in OpenAI/Anthropic.

Linus Torvalds: 'Nvidia has been the single worst company we've ever dealt with'

His other comments on Nvidia often contain expletives.
