I’m new to the electronic engineering game, and only recently made my own PCB design for an i2c sensor. Logic Analysers have always been expensive, but in recent years, they have become cheaper and cheaper. There’s clones out there that are very cheap to get. Recently, people have started using the ~ 6 euro Raspberry Pi Pico’s for it. The pico is now supported in the open source sigrok software using pico-coder’s sigrok-pico ‘driver’. I had a little trouble getting this to work even though there is documentation for it.

I’ve happily been running debian stable with gnome 43. I’m using the normal gnome-terminal that I generally open with ctrl+alt+t. It’s a hotkey i’ve configured in the gnome-settings. Having a hotkey makes it super quick to open a terminal, but that means i get a lot of them. By default they all of the same title, which is not great. It would be great if (like tmux) the window title would show the current running program.

I’ve been running my own mailserver for a while. This is not very common anymore and lots of people have problems with this due to MS and Google’s SPAM filters, lots of ISP’s blocking SMTP traffic and IP reputations of some ranges out there. I’m lucky enough that i primarily receive e-mail, have a provided that allows SMTP and have a reasonable IP address. To read my e-mail, i run dovecot imap server and over the years my mail archive has become nearly 10gb of data.

For data analysis, I sometimes use python in combination with pandas. In this post I’ll take a look at some of the performance aspects of pandas and alternatives. Pandas makes it easy to read data using read_csv (or other read_ functions). You get a DataFrame which is easy to query and plot using matplotlib.

I’m one of those weird people that still runs a “Linux router”. This means I have a PCEngines APU2 board and use a Draytek 130 modem. The reason I do this is because I like the control it gives me, and I can run things like dnsdist, powerdns in combination with DHCP. It gives me nice hostnames, so I can access my webcam via nice URL’s. I also run this blog on the machine, as well as my nextcloud instance.

K2Five’s new workflow designer is a great improvement over the old designers. Improvement and innovation can’t always be made on top of legacy supported systems. This means that some features change and/or might not be available at this time of first release. The new designer is a big change and i’d like to highlight some changes here with regards to process and activity escalations. One element that the new workflow designer currently does not have is Process Escalations.

With the new release of K2 five and it’s workflow designer, we do not have the capability to write custom code in our workflow anymore. For some, this is a shocker and unbelievable. Having no code in your workflow has been a best practice for some organizations for years and as a low-code platform, it’s a nobrainer. However, there are requirements that always required code in the past, one of those Asynchronous server events.
