This. Nothing is more difficult than understanding someone’s else code and architecture, and even if you manage that, you’re now stucked with the choices somebody else made and nobody wants that (we want to make our terrible choices!).

More than a final app, the best thing to publish as FOSS is libraries extracted from it to help other developers build there own products faster. That’s something other may want to maintain when we abandon it. And on top of that, it still help to publish your app using this lib to serve as practical example about how to use your it, of course.

As a trader, I would say this is a minor correction and we really should not read much into it. :) (of course, this is not a financial graph, but I’ve seen the similar patterns of impulse/correction in many graphs that measure opinion and/or human activity)

Basically, yes. You can configure most cron program to mail task output to you (it’s usually done by setting the MAILTO variable in the crontab, provided sendmail is available on your system).

So basically, I do things like:

0 9 11 10 echo 'lunch with John Doe at 12:20'

It sends me a mail, and I can see the upcoming events with crontab -l. If it’s not a recurring event, I then delete the rule.

My favorite cost cutting tip is to avoid big webapps running on docker, and instead do with small UNIX utilities (cron instead of a calendar, text files instead of note taking app, rsync instead of a filehosting dropbox-like app, simple static webserver for file sharing, etc). This allows me to run my server on a simple Raspberry Pi, with less than 500mb of used RAM in average, and mininal energy consumption. So, total cost of the setup:

• Raspberry Pi : 77€ x 2 = 144€ (I bought two to have a backup if the first one fails)
• MicroSD 64gb : 13€ x 2 = 26€ (main and backup)
• average energy consumption : 0.41€ (2kWh) per month

With that, I run all services I need on a single machine, and I have a backup plan for recovery of both hardware and software.

Getting used to a UNIX shell and to UNIX philosophy can take some time, but it’s very rewarding in making everything more simple (thus more efficient).

I have both a resin printer and a FDM printer, I can confirm the price difference exists, but is not prohibitive (resin is about 2x PLA). The difference of quality is mind blowing, though (in favor of resin printer). If you’re building an army, I assume you will have many pieces? If so, the difference of printing time is also mind blowing in favor of resin printer. The resin for that being that if you print 10x the same mini or your build surface, with FDM it will take 10x the same time (the printing head must move to cover each point) while with the MSLA (resin printer), it will take… 1x the same time. That’s because each layer is flashed from a PNG image, so all points of a layer a created at the same time.

An other thing to know, though, is that resin printing is way more messy. You will manipulate toxic products, that you can throw in the sink, we need gear to cover your hands and face, and resin ends up everywhere and is near impossible to clean. But it’s worth it, especially if you’re into minis. :) FDM, on the other hand, is unbeatable for functional prints (because those resin prints are damn fragile, and tend to not be perfectly at the scale you designed).

Oh, I see. Yes, that may very be a matter of point of view. For me, modding the printer is part of the fun, not something I do to try desperately to stay on the cutting edge. :) The RepRap dream of “printers that can reproduce themselves” never fully materialized, but modding is the next best thing.

Are they still sold, anyway? I mean, sure, someone who has no printer should buy a more recent one. But that was not the subject, here : the question was if it was needed to replace an Ender 3. I certainly would not, personally, it would be throwing out a perfectly good printer for incremental upgrades. Of course, it depends on the usage. For someone who uses their printer professionally to serially print all day, sure, it’s probably worth it upgrading. Me? I really don’t care if my prints are slower. I really don’t find the Ender 3 hard to get a print right either. But I’ve been printing since the wooden Printrbot Simple about a decade ago, maybe I’m just used to it.

I’m using a pi4 8gb as my server, with a pi4 2gb as backup in case the first one dies. It’s a very classic server, running postfix/courier-imap for mails, lighttpd for web, bind9 for dns, ergo for irc, sqlite3 for databases. I also use fail2ban for IDS and cron to run tons of various task. All of that is hosted on a Gentoo linux OS.

The one thing I don’t want to use is docker. I love docker for development or for deploying the main app at work, but it makes managing updates a nightmare for handling multiple services on my server (most your containers probably contain vulnerable software due to lack of system updates), and it eats resources needlessly. Then again, it’s made possible because I avoid the big webapps that usually need it.

At the very least, it means the CEO doesn’t understand the domain. It may be because he sees this part of the business as secondary and less important, or because it was developed so fast he didn’t have time to grasp the concepts, probably he was not a driving force in that effort. I certainly hope the tech side is more aware. Without more proof of CEO implication, I certainly would not bet on that horse to survive in the distant future, though.
