NoiseBert69··on Our eighth generation TPUs: two chips for the agentic era
That cooling system looks crazy. What an unbelievable density.

Oh wait, wrong Thread!

NoiseBert69··on They See Your Photos
> Guessing my exact location - Oslo Opera House - was impressive though.

Not really. They have almost global picture coverage thanks to Google Streetmaps.

They only need small snippets of a picture to geolocate you.

NoiseBert69··on The effects of caffeine consumption do not decay with a ~5 hour half-life
For me a coffee is more kind of a ritual addiction.

> GPS is also unreliable in Ukraine, especially near the front line.

There are GPS antennas that physically can block out signals that are not coming from the sky with a huge amount of decibels. Maybe Aliexpress has some of them in stock? This was heavily ITAR-ed but this ban was lifted recently.

Other option: try to sync against the DCF77 signal from Germany. Not only the beep-beep-beep time signal but also the integrated phase modulation. Jamming VLF is difficult. 77KHz is in the range of ADCs.

Then make a voter: if GPS/GLONASS/Galileo/Beidou is available prefer them, if not fall-back to DCF77. If this fails: free-running.

That's not even complicated.

You can use ESP32 with GPS modules and their PPS signals. The PPS signal from the module often has has a roughly precision around 60ns against the global GPS standard.

With that signal you can PID-control an internal timer of the ESP32 - which then can be used to timestamp audio frames. Send that to a central host over Wifi and you can use your standard localization math.

The trick is to use the internal ESP32 10MHz hardware which automatically kicks timestamps into a register if a GPIO does something. Not using high-level C constructs that must eat their way through x API layers.

This costs like 20€.

NoiseBert69··on Full Spectrum and Infrared Photography
Very nice idea! That makes it much easier!
NoiseBert69··on Full Spectrum and Infrared Photography
You’re considering whether it would be possible - and perhaps quite elegant - to use an XY‑scanner to raster‑scan the end of an optical fiber across a prism, disperse the light, and then capture the resulting spectrum with a CCD line sensor.

With that setup, each pixel on the line sensor would effectively record the full spectral content of the light at that scanned position, all in a single acquisition.

I haven't seen a single functional real-world Reticulum network in the wild.

fx = Felix Lindner

Please don't mix up the names and nicknames.

Both are highly renowned security experts.

NoiseBert69··on Geran-3 Drone Disassembly
Feels like they had to develop around their component shortage. Very weirdo microcontroller/DSP mix.
NoiseBert69··on iPhone and iPad approved to handle classified NATO information
Restricted?

Even the monthly consumption of toilet paper on a base has this classification.

Bruh...

NoiseBert69··on Hetzner Prices increase 30-40%
Due to lack of memory leaks which will stop increasing RAM prices?
NoiseBert69··on Tailscale Peer Relays is now generally available
Yes and no. It's much manual work to get WG to behave like Tailscale.
NoiseBert69··on Can a Computer Science Student Be Taught to Design Hardware?
As a computer engineer I usually copy reference schematics and board layouts from datasheets the vendors offers. 95% of my hardware problems can be solved with it.

Learning KiCad took me a few evenings with YT videos (greetings to Phil!).

Soldering needs much more exercise. Soldering QFN with a stencil, paste and oven (or only pre-heater) can only be learned by failing many times.

Having a huge stock of good components (sorted nicely with PartsDB!) lowers the barrier for starting projects dramatically.

But as always: the better your gear gets - the more fun it becomes.

NoiseBert69··on The Israeli spyware firm that accidentally just exposed itself
The German foreign intelligence service (BND) played the PR of incompetence for a very long time.

Well until press found out that they had tapped into Obamas encrypted phone calls while flying in the AF1 for a long time.

NoiseBert69··on Arm wants a bigger slice of the chip business
RISC-V is eating the "low power low performance"-niche alive right now. ARM-licensed microcontrollers (like STM32C0) cannot keep up with this price class. That's a huge business.

Have a look at WCH. If you are used to the ST-HAL style you get that stuff running within a hour. They stuff works will fully opensourced compilers.

NoiseBert69··on High-Altitude Adventure with a DIY Pico Balloon
Jet engines are tested for this.

They basically can shoot (not only throwing!) entire frozen chicken cadavers into engines with zero damage.

The only way they managed break the entire engine was to place little explosives on the turbine wings. Even that didn't cause a fatal disintegration of the jet engine.

Somewhere on YT there's a super entertaining video from a test facility.

NoiseBert69··on High-Altitude Adventure with a DIY Pico Balloon
There are thousands of weather balloon starts every day without any damages to airplanes.

It's not factor as long they are not crossing a specific size/weight - jet engines and windows from airplanes are tested to withstand a direct impact.

NoiseBert69··on Defeating a 40-year-old copy protection dongle
https://eur-lex.europa.eu/eli/dir/2009/24/oj/eng

Directive 2009/24/EC, Article 5 + Article 6

Under special circumstances it's legal within the EU do do this.

And removing a freaking old copy protection dongle to allow emulation of the software you legally are allowed to use falls under this.

NoiseBert69··on We asked 15k European devs about jobs, salaries, and AI [pdf]
There are many tools available in Germany that support you doing your tax filings. They have endless questionnaires in (tax law free) easy language that guide you through all the taxing niches. They not only respect all rules regarding the laws but also the latest jurisprudence.

Like: If you have a lockable, separate office and work (almost) exclusively from home, you can basically deduct the entire room for tax purposes (rent + electricity + heating + insurance + etc).

That can make a huge chunk.

NoiseBert69··on We asked 15k European devs about jobs, salaries, and AI [pdf]
Reality is ~36-38% if you learn to spend money strategically so you can fill a proper tax return.

I never paid 42% my entire engineer life.

NoiseBert69··on We asked 15k European devs about jobs, salaries, and AI [pdf]
These numbers are far off reality.

80k€+ isn't a high salary for job in a Tarifunternehmen if you stay with it for 5+ years.

Many of my colleagues cracked 100k€ this year without being AT and having crazy high position ratings.

NoiseBert69··on We asked 15k European devs about jobs, salaries, and AI [pdf]
I don't trust these numbers for Germany.

Why? Have a look at all the Tarifunternehmen salaries. 80k-90k€ is pretty much a standard salary you can reach after 5 years (with maybe changing your position once within the same company).

Feels like their dataset has significant sampling gap in some very big industries here.

NoiseBert69··on Mobile carriers can get your GPS location
Honestly: MC and MT are classical bloated Arduino projects with a giant single big-loop and an interrupt coming from the LoRa modem.

Both projects are hitting their limits because of this. Every new feature and every bug fix causes endless amount of pain and breakage.

I was involved in both - and gave up because of this.

IMHO both projects need some kind of thin-client which delegates most of the functionality into the client. Only keep some basic LoRa/Message Buffer/Routing/Battery Saving functionality in the hardware itself.

NoiseBert69··on Mobile carriers can get your GPS location
Meshcore and -tastic have the huge problem that the encryption keys are bound to the device and not the app.
