FredFS456··on TCP Use-After-Free: CVE-2026-98432 / CVSS 9.8
Note that even the latest OpenWRT is vulnerable to this, I'm running OpenWRT 25.12.6 and the kernel version is 6.12.112
FredFS456··on Samsung running a TensorFlow lite model on 960x540 image to track you
https://abliteration.ai/

But also if you're working on a local device, any Chinese model will agree to it most of the time.

FredFS456··on Show HN: Steal My Bitcoin
DoS is independent of the vulns though. From what I understand, you can craft a request of x size which consumes ~200x the memory on the server. Parallelize that and you can DoS servers with only a few GB of memory, even with the 1MiB Nginx limit.
FredFS456··on Show HN: Steal My Bitcoin
They can be running a vulnerable version of PHP but also recording all traffic in a way that does not allow for wiping evidence afterwards. For example, if the PHP server was behind another server routing the raw IP packets and running tcpdump. Since the author of the site controls the TLS cert private key, TLS does not protect again the author eavesdropping.
FredFS456··on MiMo v2.6
I prefer GLM 5.3 (Flash or not) over Deepseek 4.1 Flash because the GLM models are significantly less verbose.
FredFS456··on The largest electric aircraft just flew [video]
At cruise, yes. However during takeoff and go around they run at higher RPM to develop more thrust. Using batteries for takeoff and only using fuel for cruise or backup power is smart.
FredFS456··on Over 150k Flights: Airlines Just Flew the Busiest Day in Recorded History
Depends on where you're flying to and from in Asia, and how far.
FredFS456··on Crypto in 2026: Oh, This Is the Bad Place
From my own comparisons, when converting, say, $1000 USD with Wise the spread+fee is about half of any of the banks that I have accounts with. Where Wise takes a huge cut is if you convert $10 at a time.
FredFS456··on Tin Can, a 'landline' for kids
Landlines only work when there is no power if: - you use an old school landline phone (not cordless) - your landline is actually copper going to the house (I've seen fiber to house + conversion to twisted pair by a box with a battery) - upstream infrastructure either still has (possibly battery) power
FredFS456··on America vs. Singapore: You can't save your way out of economic shocks
I think specifically for example of getting Nvidia chips to China, many Singaporeans would say that that is only illegal because the US deems it so. There is no moral reason.
FredFS456··on America vs. Singapore: You can't save your way out of economic shocks
I agree with you that the migrant workers are effectively a serf class. However, I think it's fine that the SG government severely discourages owning a car. It's a small island with lots of people, there would be gridlock if everyone wanted their own car. The public transportation system is amazing and works well.
FredFS456··on Eulogy for Dark Sky, a data visualization masterpiece (2023)
I haven't used Dark Sky but on my Android phone, Meteoswiss is definitely very very good
FredFS456··on Bose has released API docs and opened the API for its EoL SoundTouch speakers
They do have very basic EQ but for sure you have enough documentation to modify the speaker itself if you'd like.
FredFS456··on Bose has released API docs and opened the API for its EoL SoundTouch speakers
I bought one just this week because of this. They really went above and beyond:

- mechanical CAD, schematic and PCB files: https://docs.teufel.de/download/MYND/Open_Source_Hardware_Fi...

- firmware: https://github.com/teufelaudio/mynd-firmware

- Bluetooth API documentation: https://cdn.teufelaudio.com/image/upload/v1748589486/product...

- battery repair/replacement guide: https://cdn.teufelaudio.com/products/MYND/pdf/Teufel_MYND_RM...

I believe that they designed the mechanical parts to be 3D-printable as well.

FredFS456··on Why Nextcloud feels slow to use
I think you could replace Nextcloud's syncing and file access use cases with Syncthing and Copyparty respectively. IMO the biggest downside is that Copyparty's UX is... somewhat obtuse. It's super fast and functional, though.
FredFS456··on The Synology End Game
There are some new NAS boxes hitting the market (UGreen being one of the brands that are cheaper, but also Minisforum) which have solid hardware but aren't locked down at all. They're just x86 boxes with bog-standard hardware so you can just run whatever OS you want, and they support that use case.
FredFS456··on Is TfL losing the battle against heat on the Victoria line?
Platform screen doors can isolate tunnel temperatures from platform temperatures.
FredFS456··on It's 2025–Why Are Banks Still Getting Authentication So Wrong?
Zurich Kantonalbank (ZKB) has a very similar system, probably because they're also a big bank in Switzerland
FredFS456··on If you get the chance, always run more extra network fiber cabling
Multimode transceivers are still a slight bit cheaper ($30 for 10GBASE-LR vs $22 for 10GBASE-SR on fs.com) but that's more than offset by the single mode fiber being slightly cheaper, even for short distances.
FredFS456··on Announcing the data.gov archive
IMO US elections have already been less-than-fully-democratic for a while, what with the voting registration and ID nonsense, as well as obvious gerrymandering and voter intimidation. At the very least, significantly less democratic than a number of other western countries.
FredFS456··on Show HN: Using YOLO to Detect Office Chairs in 40M Hotel Photos
> There was a LTT video where they mentioned how WiFi used to be better in some locations so those rooms were more desirable and the hotel's solution was to make it standard for everyone. They seemed to be suggesting that they brought down the quality rather than balanced.

This was from their podcast 'WAN Show' a week or two back, specifically about hotels in Las Vegas.

FredFS456··on Exotic new superconductors delight and confound
There's some fusion startups successfully making >10T magnets using ReBCO tape now, so hopefully things will scale up/cost down enough to be used in MRIs.
FredFS456··on Exotic new superconductors delight and confound
There's a few fusion startup companies using superconducting ReBCO tape to make their magnets. From the results that they're getting, I think we've largely cracked the engineering problems of making "wire" from ReBCO and it's largely just a scaling game now. I do want to point out that they're still cooling with liquid hydrogen at ~20K for high current capacity though.
FredFS456··on Show HN: Bluetooth USB Peripheral Relay – Bridge Bluetooth Devices to USB
A cheap USB switch would also work, that would reduce the switching to switching monitor inputs and pressing the button the USB switch
FredFS456··on Thunderbird for Android Now Available
I dunno if it's native or not, but the Fastmail app doesn't work when you're offline.
FredFS456··on Jump Trading, Virtu and the 'hidden optical fibre cable' under an Ohio field
Speed of light in an optical fibre is about 2/3 that of the speed in air
FredFS456··on Amazon reveals first color Kindle, new Kindle Scribe, and more
When I bought my Paperwhite around 2013, I noticed that ads were an option on the kindles sold in the US but not in Canada. In Canada there was only the no-ads version.
FredFS456··on Hell Freezes Over as AMD and Intel Come Together for x86
ARM cores can be used with UEFI and other hardware autodiscovery mechanisms. Not a limitation of the instruction set but rather the willingness of vendors to do the work. Many ARM servers have UEFI implemented.
