RachelF··on My smart sleep mask broadcasts users' brainwaves to an open MQTT broker
wow! Thanks for that.

Yes, it is very lacking in details. The Claude output would have been interesting, or a few logs or protocol dumps.

The lack of detail makes me suspect the truth of most of the story.

RachelF··on Gemini 3 Deep Think
Not in my experience with Gemini Pro and coding. It hallucinates APIs that aren't there. Claude does not do that.

Gemini has flashes of brilliance, but I regard it as unpolished some things work amazingly, some basics don't work.

RachelF··on Building a 25 Gbit/s workstation for the SCION Association
There fans are still good, but not the quietest anymore.

Noctua no longer manufactures them, they are now made by YS Tech.

RachelF··on The Vietnam government has banned rooted phones from using any banking app
I don't understand the threat model that banks worry about on rooted phones.

What is it? I can access their websites on a PC running as root or Administrator. What is the problem with rooted Android phones?

RachelF··on Why is the Gmail app 700 MB?
Mine is not 200MB on Android - the base apk is 67MB + 32MB for the ARM v8a specific libs. This is the code, the local caching and other data might make up the rest.

For Android, you can check [1] Download the apk, rename it as a zip and look inside to see the files.

A quick file analysis of the 67MB shows around 58MB of java code and some 32MB of ARM libs, 31MB of this is the libvideochat.

RachelF··on Guarding Against Physical Attacks: The Xbox One Story (2019)
Interesting timing, given that the PS4 has been hacked via various exploits, and the PS5 has just had its root encryption keys exposed.
RachelF··on Anna's Archive loses .org domain after surprise suspension
Anna's archive has a great analysis of the Spotify data.

They identify a huge surge in tracks that few listen to after gen AI started.

The analysis is worth reading. The distribution is (Pareto)^3 ~99% of the tracks played are 1% of the catalogue.

RachelF··on Linear Address Spaces: Unsafe at any speed (2022)
> iAPX 432 Yes, this was a failure, the Itanium of the 1980's

I also regard ADA as a failure. I worked with it many years ago. ADA would take 30 minutes to compile a program. Turbo C++ compiled equivalent code in a few seconds.

RachelF··on 2026 will be my year of the Linux desktop
Windows has been my main operating system for the last 35 years (from version 2). I've used Linux and to a lessor extent BSD and Mac as well, but my main desktop has always been Windows, as it ran most of the apps that I needed.

Windows 11 UI and spyware are so bad, that Windows 10 is where my 35 years of using Windows as my main OS has ended.

RachelF··on Linux is good now
The Chinese tech manufacturers are so sick of the HDMI licencing mafia that they've developed their own replacement for it:

RachelF··on What Happened to Abit Motherboards
In the late 1990's many HP workstations used Abit motherboards.

I remember being surprised that HP did not make the boards themselves.

RachelF··on Oliver Sacks put himself into his case studies – what was the cost?
Or more recently Dan Kahneman, Dan Arielly or Stephen Jay Gould have also been caught fabricating details or whole results.
RachelF··on Show HN: I made a spreadsheet where formulas also update backwards

RachelF··on Show HN: I made a spreadsheet where formulas also update backwards
A lot of the time engineers are focussed with solving a problem, to build a working machine/program, while academics just want to publish.

This is also true with patents.

RachelF··on Bit flips: How cosmic rays grounded a fleet of aircraft
I would argue that designing avionics without EDAC is negligent design by Airbus.

Most modern servers at least implement ECC on their RAM. I would expect flight electronics to be designed to a higher standard.

RachelF··on Show HN: Gemini Pro 3 imagines the HN front page 10 years from now
Sad to see Half Life 3 hasn't been released yet.
RachelF··on Tiny Core Linux: a 23 MB Linux distro with graphical desktop
As someone who used QNX back then, they didn't target end-users but embedded and real-time users.

They were expensive too. You had to pay for each device driver you used.

RachelF··on Why are 38 percent of Stanford students saying they're disabled?
Sadly, society also optimizes for cheating. Meritocracy is a myth.

In many ways Stanford is preparing students for the real world by encouraging cheating.

RachelF··on The RAM shortage comes for us all
Perhaps we'll have to start optimizing software for performance and RAM usage again.

I look at MS Teams currently using 1.5GB of RAM doing nothing.

RachelF··on PS5 now costs less than 64GB of DDR5 memory. RAM jumps to $600 due to shortage
Perhaps the memory manufacturers have seen how much Apple gets away with charging for the memory on their laptops and have decided to copy them ;-)
RachelF··on PS5 now costs less than 64GB of DDR5 memory. RAM jumps to $600 due to shortage
Well put. Since the 1980's consumer has been driving the segment. Even supercomputers were built out of higher end consumer hardware (or playstations in one example).

The move to cloud computing and now AI mean that we're back in the mainframe days.

RachelF··on Unpowered SSDs slowly lose data
Endurance going down is hardly a surprise given that the feature size has gone down too. The same goes for logic and DRAM memory.

I suspect that 2035 years time, hardware from 2010 will work, while that from 2020 will be less reliable.

RachelF··on Arduino published updated terms and conditions: no longer an open commons
Raspberry Pi was never really that open hardware-wise. They've IPO'd and gone fully corporate/profit driven now.

The ESP32 is probably the most vibrant platform now.

RachelF··on Asus Ascent GX10
These very narrow speed measurements are getting out of hand:

1 petaFLOP using FP4, that's 4 petaFLOPS using FP1 and infinite petaFLOPS using FP0.

RachelF··on Ask HN: What are people doing to get off of VMware?
That's how he gets paid - increasing short term stock price.

RachelF··on Free software hasn't won
I really don't understand why they do this - what is so special about banking apps vs a banking site in a web browser.

What is the particular threat model of a rooted phone?

RachelF··on Become unbannable from your email
The counterpoint for having your own domain is that emails you send have a good chance of being classified as spam.
RachelF··on Mini smartphones from Japan [video]
Yeah they got burned. Sony stopped selling their Clie PalmOS phones/PDA's in the USA as they said Americans were too lazy to read the manual.

The innovation of the iPhone was the capacitive touch screen (a Japanese invention) coupled with an OS that was very easy to use (no manual reading required). And of course Apple's marketing genius.

RachelF··on Microsoft 365 Copilot's commercial failure
Many other recent Microsoft products are below average. I'm thinking Teams, Outlook, Windows 11. Azure and Office are better.

I guess they spend their money on sales and licensing and not on developing good products now?
