Yeah. That is a problem with older Raspberry Pis, which do not have a keyboard. It is possible to use a GPIO port for this, and shut it down with an attached button. But one has to be careful not to use the port unless it is configured prop

Because you can squeeze out more money from it that way. Having everything collapsed in one giant data collection is just the natural equilibrium state from the physics point of view.

Electrical power consumption is a point worth looking at.

You can use a Raspberry Pi (perhaps a Pi 400) if you work around the fact that the internal flash memory is not made for constant writing. Thus, you have to arrange the system so that it is read-only in normal state - which is not difficult

CMake is marketed heavily, but not all things which are said about autotools are accurate. Here is a video from somebody from KitWare who compares autotools to CMake: https://youtu.be/8Ut9o4OdSC0?t=459 In this section, he k

So, what would you say what these tools have learned and taken from autotools, and what are the core ideas with which they were improving? I was looking around for a description of what the core ideas of CMake are and could not find much, e

I'd agree with that. If a build happens on a build server, it does hardly matter if it takes an extra minute. What matters for developing and debugging stuff are fast incremental builds. And for this, one just needs to type "make&

Just to add, Guix configuration does not only look declarative - it uses a mostly functional language in a side-effect style to define the builds, in the same way as NixOS, just with a language which is established, well-supported, minimal,

This is exactly my biggest problem with some other tools: That they try to automate everything with lots of "magic". And this does not lead to clearly understandable, well-defined systems which are maintainable in the long run. If

I see that point! On the other hand, it is generally strongly encouraged to keep generated files out of source control repos. Especially since one cannot merge them in a meaningful way.

The problem with conan is that it is yet another language-specific package manager. This is especially fatal since the importance of pure C and C++ projects is shrinking in proportion, and both are more and more used in cross-language proje

Make does what it does surprisingly well: It runs commands on files based on a description of dependencies. There is no shortage of would-be successors of make, but so far none of them has succeeded, which supports the hypothesis that &quot

This is by construction and is nicely explained by the slides I linked before. Basically, autoconf generates a makefile which will work for your architecture. It does that via a script which is called "configure", which generates

Apart from that the embedded universe needs to support a lot of CPU architectures, the demand for building on different hardware and slightly different library interfaces is unlikely to disappear. Just think in desktop apps using Qt4 /
