  • It’s probably no coincidence that a large amount of technical people are some form of neurodiverse, I’ve run into a lot of others with ADHD working as a SWE, definitely suspected some as well when I worked as a Mech Eng (wasn’t diagnosed then), and there’s definitely people with autism as well.

    Lots of our processes are flavours of continuous improvement, agile is amazing when it’s done correctly, as I get older I’ve started pushing more for that.


  • Terminal usage is a tool just like GUI tools, I don’t think it’s helpful either to preload people with the belief that it’s some arcane tool that takes years before you can start using it, like anything you pick it up by doing.

    Can’t really say it’s 100% optional as a blanket case either, heavily depends on a user, my work I’ve depended on having a terminal for years, and that was even before I moved into SWE, I’ve seen lots of business developed processes put together as an amalgam of batch files, VBA/VBS, and python because they needed to put something together with what they had rights to.

    Be honest that I don’t see the terminal as a barrier to Linux anyhow, for the use case of “I browse the internet and use office programs”, you absolutely do not need to drop to the CLI, at least not for Debian or Mint, can handle installs and updates through their graphical package managers. Most people probably aren’t setting up services or the like on their machines, and if they are they already require terminal usage on any operating system.




  • Haven’t looked into it but do shops offer lube analysis services? Yeah you could send out your own sample to a lab, having it as a shop service would be way more accessible to people.

    Though, in my experience, getting people to commit can be a pain, lots of “yeah I know we have a long p-f interval and it’s super noticeable before it functionally fails, but it’s not that much effort so I’m doing needless maintenance anyhow just in case”, which end of the day you do you.






  • Let’s say that a referendum passed, how would that even work? Found this Supreme Court remark from Chief Justice Beverley McLachlin in 2014 when I was searching around for an answer of “is that even possible?”, apparently the Feds referred that question to the scoc during the Quebec referendums in the 90s, (see section 5) and the answer seems to be, certainly not unilaterally (I’ll read this in detail when I have a chance). The also touch on treaty rights which is my question as well, Alberta is like all treaty land, how would the indigenous land rights be handled? On top of that, as far as I recall there’s a tonne of crown land in Alberta, again, how would that be handled?

    I don’t have answers to these, just something I think about when these rumblings come up. I have my doubts about the actual popularity of an Alberta sovereignty movement, and frankly Canada is stronger with them than without, like with Québec it would be a loss to the federation.

    i was thinking along those lines for equipment monitoring stuff, klipper works with Prometheus & grafana (have metrics from my printers), was thinking about looking at using the extra accelerometers I have to do something like vibration monitoring.

    I could see using a second sbc for extra sensors as well for support, thinking about printers that don’t run klipper, so long as you can correlate data it should still be useful. Honestly kinda thinking something similar to PLC data, was fantastic for fault finding and failure investigations, also useful for process control + condition based maintenance, there’s a heck of a lot that could be done with it.

    Edit: You have me thinking about this now, what would be really cool is an ability to anonymously federate data tied to events, I recall some enterprise software I used like 5-6 years ago could do this with condition indicators, I have 2 machines, I won’t see every failure mode, but if we had 1000 machines you can get much more accurate information about things like MTBF. Heck I’d even just be happy with some community FMEAs, really just thinking of taking a technical approach to my printer maintenance and usage.


  • What type of filament? Acetone doesn’t do much to things like pla or petg, stuff that works aren’t things you generally want around the house, industrial solvents and stuff. The jar of acetone can soften it up some but you’ll need to soak for some time, I’ve used MEK too, but that’s in the “don’t keep that at home” category, it’s really flammable and should use ppe (I mean should use ppe for a lot of the stuff we use, 99% IPA is harsh on your skin, I use nitriles because it irritates my hands something fierce.)

    Cold pull as others recommended, nozzles are consumables, def should keep some around. Cleaning filament works pretty well in my experience if you have a partial clog.

    I’ve been there though, first block I didn’t use a sock and the set screws got encased in degraded petg, I ended up scrapping it and putting it on the shelf as a learning moment, def recommend a sock if you don’t have, it’s saved me a lot of grief.




  • Seen this clip from some american fundie podcast that was… a choice.

    This person was asked something like, if you could have world peace, but all governments become socialist, would you do it? They said no and fucking justified their answer with a partial quote from something like Deuteronomy 15:7-11, claiming that well the bible says there’ll always be the poor so socialism is actually bad because of that, and a quick search to see if I could find it there’s a lot of stuff echoing the same stuff, that socialism is unbiblical etc.

    What the actual fuck is wrong with these people? I’m irreligious but was raised Christian, this is so vehemently counter to my understanding of Christian teachings (the flavour of which I was raised has atheist ministers so there’s that), which was more or less, raise everyone up, accept everyone for who they are, help people, don’t turn a blind eye to injustice and like just be decent to each other. Was this podcast prosperity doctrine shit or something else because yeah wow, it’s honestly sinister to me.

    I kinda hate they don’t put error bars on the chart, it’s statistical noise that’s likely all within the MoE.

    Like in statistical process stuff, you can’t say there’s a trend from a singular data point, western electric rules for example, if you saw multiple consecutive data points and/or large swings maybe you could conclude a trend, but as it stands yeah nah no change.


  • Yeah, echoing this, I’ve run Linux off of my external nvme enclosure for is testing as well, mitigates the heat and durability issues but was nowhere near the best experience, though it’s supposed to be able to do 10 Gbps so it’s nice in pinch, it’s my rescue and iso drive mainly.

    Standard USB keys get toasty as heck just from regular usage, especially the metal bodied ones.

    Personally I view SD card installs with a similar level of concern to a USB install, had those crap out with no warning in the past (though tbf, it’s only happened a handful of times), I backup configs for my stuff running off of SBCs for that reason.


  • If I recall, doesn’t a leak need to be pretty substantial to detect in the audible frequency range?

    I’ve trialed and pushed usage of ultrasonic tools for this when I worked in maintenance engineering, some of my colleagues used then quite extensively and were able to justify the costs after the found a single tool air leak. Were also pretty interesting for bearing inspection, could pick up on damage far earlier than it’d be detectable with vibe or acoustic tools (certainly far earlier than thermal), they enabled some interesting lubrication practices too, aiming to prevent over-lubrication.

    I found this USB ultrasound microphone that’s supposed to be compatible with any recording application. My experience, just a UT microphone was more than enough to pick up leaks, it’s very directional and presumably you’re going to be fairly close to the source, it is expensive at €250, might be something to keep in mind.

    I like the idea that was brought up to maybe try a frequency analyser first? Spectroid on android or Sound Spectrum Analysis were recommend by Voron Deaign for 3D printer tuning purposes (belt tension, though I use a printed tensiometer for that these days). Only thing I can think of is yeah, will a vacuum leak be detectable in the audible frequency ranges? Probably worth a try regardless.
