How long is too long for a build? More than 10 minutes. There’s a large behavior shift between 8 and 12 minutes. Less time is always better.

You can install Python packages from source code repositories. This is really useful when you do not want to insert an extra step of creating and uploading a package to the PyPI repository. Most notably, it’s most useful to download your packages from your GitHub source repository.

Want to install Python packages into a virtual environment, but still be able to develop them with ease? Look here for the documentation on so-called “editable” installs that allows you to do this.

Now you’re wondering about opto-isolation for Ethernet. Yes, there are Ethernet surge protectors. Just be careful if you are using this in conjunction with PoE. And of course there are other methods like using a UPS at the switches to protect from surges.

Darktable camera support for Raspberry Pi? No, not yet. Look here, make sure you upload your RAWs.

So, how do you capture RAW images with the Raspberry Pi camera? Look here. Unfortunately, the process is more complicated than it should be due to undocumented proprietary systems that have to be reverse engineered, but here it is. First, you put the camera in RAW capture mode. It will emit JPEG + RAW images, the RAW data in an incompatible, non-standard, undocumented format. Next, you run it through some libre software to convert the RAW data to a DNG, which you can then process any way you please using the tools of your choice.

Also interesting is that the forum members found some source code on the same hardware in earlier mobile phones. Unfortunately some of it was programmed against an obsolete interface.
Here is more useful and interesting information on the Raspberry Pi camera.

In addition to Sphinx, ReStructuredText, and readthedocs theme for generating documentation, there is also this MkDocs system that allows you to write your documentation in Markdown, which is much more popular nowadays.

This is interesting article that demos a conversation with the Microsoft Virtual Assistant. Yeah, the Microsoft Virtual Assistant isn’t very good at responding and answering questions.

So, there’s been questions whether a band that calls itself Metallica is the same one as such a band that existed many years before. Well, let’s see if we can find their trademark registration.

Ah ha, there are many companies using the same trademark registration, but in disparate industries.

This is a really interesting article that I found about copyrights on tatoos. The laws are ambiguous as to the ownership of the tatoos, but one thing is clear is that if there are questions, they should be asked before the ink dries. Well, before the tatoo is applied.

First of all, finding out how to control the Windows Update settings is much more complicated nowadays: you have to go fish through a new “Settings” app that is not even linked from the Control Panel.

Second, modern Windows assumes an unlimited bandwidth connection unless you state otherwise.

Third, Windows assumes that you are connected to a symmetric unlimited connection by having peer-to-peer updates enabled by default, when in fact many Internet users are connected through asymmetric connections with faster download speed than upload speed.
