Hacking the Linux kernel in Ada
For this three part series, we implemented a ‘pedal to the metal’ GPIO driven, flashing of a LED, in the context of a Linux kernel module for the NVIDIA Jetson Nano development board

You probably don’t mean equally possible as in the sam likelihood, or ?

I don’t think virtual cards are meant to be more anonymous? My understanding is that it prevents that your original card details get stolen in online transactions

I use it for quite some time and am happy with it. I have not noticed bad search results but also have not compared really. I general I have found what I was looking for.

Building an 8-Bit Breadboard Computer - Austin Morlan

I use my company laptop for work, it other than that I only have the Pinebook. For personal use it’s ok, probably not the fastest but ok. Also the memory is no problem for me.

I always feel to connect some cables and make a light go blink blink very satisfying. There are cheap sets with all sorts of cables and lights/sensors.

Then choose your language of choice and make it blink/summm/ measure the temperature/air pollution or so

Once you have it choose another language and repeat 😀

(BTW, I use a Raspberry Pi 3 as a Nextcloud server, works fine, this might depend on your expectations)

Ada is really good at making this kind of bit hacking very transparent. It might be interesting to create a Ada version of the examples in the Article to illustrate this. Even the Rust solution looks really messy compared to how Ada approaches this.

Happy to report that the PineBook Pro is great (considering the price point) and the display is really good even compared to any kind of Laptop. 😀

I suggest lite-xl.

It’s a very new cross platform development based on SDL2 for graphics and using Lua. It’s quite minimalistic but still has the neccessary editor functions, plus you can write plugins in Lua if something is really missing for you.


Suse was regularly bundled with some Computer Magazins on CD and later DVD. In Germany that was the easiest way to get hold of a new Linux bistro. I still like it.

I think you look at it from two quite extreme angles. A ‘very good’ normal bike (no e) for 600€ would be seriously cheap. It might depend on where you by exactly, online vs bike shop and so on but for very good I would have guessed more around 1000€. It probably depends also what type of bike you prefer . Seems you are not keen on a city bike.

On he other side an ebike for 3000€ is definitely in the higher price range. You get something decent for ~2000€ as well. This would reduce the price difference.

The classic example for an ebike is that the breaks have to be set up for the higher demand, so you should ensure that you have that on your normal conversion bike.

There is also a difference in handling if you have a front/read engine or a middle engine.

Other than that I would think you can convert a bike as well. Not everyone can do it or wants to spend the time.

It’s not a review website in that sense, but I sometimes find slant.co quite useful.

The usual questions are best for this, best for that…

Sounds a bit it like writing in Markdown or org-mode and then use the tool of your choice (e.g. Pandoc) to produce the formatted result.

I am using both, LibreOffice and MS Office for work. Mostly to experience how it works. On my work laptop I only have LibreOffice 7.0 (the company provides the software and should update it) so not the latest.

In the end I use Calc over Excel, not because Excel is bad per se, but because for my use case it does not make a difference and LibreOffice feels more fresh. I also use PowerPoint over Impress, as there were several things in Impress that did not work so well (making a table smaller, show lines to align form to other elements, …).

Pacman does not update or install AUR packages. That’s probably the main difference between pacman and yay (or similar AUR helper)

Ok, out of interest, how does this work?

You (as aggressor) scan all your known mobile numbers agains let’s say Signal and discover that some numbers use Signal. That I understand. But now what? Unless you are the company Signal you would not have access to further data, or ?

I have a Nextcloud for my own, works mostly well, but it requires some effort here and there and I oft wondered what my dear users would say (if there were any) if it takes me several days again to fix some small issues or renew the certificate. Plus I know nothing about security and can only hope everything is all right. Once you set email, messenger etc. up for larger groups I could see the efforts to keep this stable and secure to be quite high. It’s probably a good solution for the privacy problem but I am not so sure that it is a solution that is manageable or even available for many and therefore a good solution overall.

When it comes to states spying you then there is no safety. The state can always just send someone over to put a gun on your head (or the legal equivalent) and voila, you yourself give them your data.

And I understand that states are very different in their (perceived) legal integrity, but if I should guess ( no evidence) then all the encryption and safety development benefit criminals most. Also some journalists and dissidents but mostly criminals to do their criminal business and in the whole, if you have the fortune to live in a state that can be mostly trusted I prefer that Police has some lever identity this kind communication. Not in-similar to when Police is allowed to tap your phone (after a judge signed off). Not many people where concerned about that.

So so in the end I feel the bigger threat are private companies who sell all your data for the highest bidder regards of the bidders intention. And provided you trust Signal, ProtonMail and Tutanota then they definitely reduce the risk there (imho).

I think an important difference is that we are comparing companies that definitely sell your metadata to companies that could sell your meta data but where there is no known case (to me) that they actually do, e.g Signal. So it comes down to trust.

I just noticed that this video is also available on Odysee.


I don’t know this platform, but can’t be as bad as YouTube, no ?

Hmm, the style of the video is maybe a bit pushy and I am not sure if it is useful to make a case with the Facebook, Whatsapp, Instagram connection and then turn around and say because this lot is bad all other alternatives like Signal etc. are equally bad, but I have to admit that it makes you think.

I have read several times that meta data leaking can be as bad as access to the actual message and I think he explains well why that might be.

I am less clear what to do about this. It is unlikely to set up a network of people and only communications with them in this network and at the same time to ensure that no one in this network communicates with anyone else. So they communicate with you, but only you ?

My view is that I am less concerned about state access to my (meta) data. They have a lot anyway, with certificates, passport, medical record etc… My concern is that this data is used and misused for a small fee by private companies and here it seems to comes down to trust. Do I really think that Signal or Tutanota sell my data in the same way as Facebook does ? Other than that I don’t see how people who want to be able to communicate in the digital world with other less tech savvy people can do so.

Are there projects out there who next to encryption focus on minimising or avoiding meta data?

Video conference supplier review by Berlin state
The data protection officer of the federal state Berlin has issued an updated report in German which Video Conference supplier are recommended to be used from a legal perspective. The report uses a traffic light system 🚦so it should be possible to get an initial view for non German speaker as well. Many of the concerns are actually not technical but more contractual that would prevent the legal use in Germany.

Giving Ada a chance
An in-depth look at the Ada programming language, its history, and what it has to offer developers today. As well as a fistful of my humble opinions.

Genode OS with new support for Pine A64
Genode OS is adding Pine Allwinner A64 with the intention to eventually support the PinePhone by end of 2021. A detailed blog describes the journey.

Erlang OTP 24 Release Candidate 1
Highlights: - The BeamAsm JIT-compiler has been added to Erlang/OTP and will give a significant performance boost for many applications. - The JIT-compiler is enabled by default on most x86 64-bit platforms

Modula 2 reloaded in 64K virtual machine
Based on the CM/P Turbo Modula 2 this implements a re-engineered version to run in a 64K virtual machine on any platform. Small enough to fit on almost every micro-controller like AVR.
