A melbournian with many interests:

  • Christian (very liberal)
  • Embedded Linux Engineer
  • Magic The Gathering judge
  • Mechanical keyboard enthusiast (mostly DIY, all very small, Colemak layout)
  • Trying to get into woodworking

All too often I come off as argumentative, I'm working on it but definitely a work in progress. Also frequently more pedantic than I'm comfortable with.

Well I have An Problem.

I need a single 15 ohm 0805 size resistor, but dickhead me ordered 0402 size instead. Should I try to yolo-place an 0402 anyway?

@trib @jpm 4 0402's would actually work fairly well......

@jpm @trib A truly cursed fix.

@Zagorath @zerakith recumbent trikes are excellent at low speed manouvers, which can be a boon in busy areas where any bike must be walked. I only once tried to corner too fast and that was faster than I corner on a bike anyway.

Hills are fine, in theory better than a bike as you have something to push against. So if you are light and have poor arm strength you can put out more power in a recumbent. Or just someone with legs stronger than that

They are trash at going through narrow spaces.

@FartsWithAnAccent @lemmyreader I loved my tadpole. Super sad that I haven't been able to find the budget to get one again since I had to sell it when I moved back in with my parents.

Um, removing lots of code is the type of thing engineers celebrate. I love when I fix things by deleting code.

Those are the good days.

@Rentlar are train tunnels cheaper than bus tunnels? The ones that get built tend to be because single lane traffic tunnels are rare (and dangerous) and the are a larger bore than a train tunnel.

LovesTha,
@LovesTha@floss.social avatar

@Rentlar I though two single track tunnels were faster to bore than a single double track tunnel.

I have a sneaking suspicion that the default error reporting from nix tools is pretty good for devs changing things deep in the bowels of the nix ecosystem, they are much more likely to have changed something core that the deepest part of the error stack is applicable.

But end users are much more likely to want the other end of the error stack.

I think I need to default to '--show-trace'.

The default being 'head + tail' would probably be more useful to everyone.

C: runs on Mac

BONUS: is

I’m so close to writing some quick and dirty thing myself…

@vsaw I suspect that some of that plumbing may be part of HomeAssistant in a way that could be useful to you. But while that suggestion is nicely FOSS, it isn't really a software solution (HA really wants HW to run on, not just a VM//docker)

Personally I think a 3am cancelling of a 6am meeting is worse than a 3am invite to a 6am meeting.

At least with the 3am invite I can enjoy a full nights sleep.

Designing my next minimalist currently. Currently I have:

  • One less column and one more thumb key per half compared to the current keyboard, for 5 columns and 4 thumb keys

  • Low profile thumb keys

  • Per key RGB (don't have to populate or use, but could be nice)

  • No case, going for flat desk mounting

  • Horizontal scroll wheel
    or

  • Joycon thumbstick next to thumb cluster

Anything else that I should consider adding?

I'm trying to figure out what is wrong with my little old Optiplex running NixOS.

Every minute or so iowait spikes to 50% and everythign is sluggish. iotop shows nothing interesting, no app is doing more than 1M/s, total is <2M/s.

dmesg has no new events in that time, but I do have a USB port that keeps dropping and coming back (could it be that stumbling and recovering without a disconnect? I don't think so as those disconnections occur without high iowait)

Any ideas?

LovesTha,
@LovesTha@floss.social avatar

@jpm Any good way to measure?

(I'd love such events to be shown in dmesg....)

LovesTha,
@LovesTha@floss.social avatar

@jpm Looking at iostat it did appear that a small amount of writing was occurring when the iowait is high, but not enough to be concerned.

I did some quick benchmarking and this SSD is slow writing 2G with dd took 102s for 20.9MB/s (read is the respectable 405MB/s for a sata SSD) which is inline with teh randwom write speed listed at https://www.harddrivebenchmark.net/hdd.php?hdd=SAMSUNG+SSD+PM871+2.5+7mm+128GB (which is the drive model and capacity I'm playing with)

A half full partition shouldn't be that fragmented that a big write is that bad

LovesTha,
@LovesTha@floss.social avatar

@jpm I probably should replace this SSD

LovesTha,
@LovesTha@floss.social avatar

@jpm It's a 5th gen i5 optiplex that I purchased second hand. So the SSD is plausibly the original and about that old.

LovesTha,
@LovesTha@floss.social avatar

@jpm And the first hit for "nixos trim" is a reddit post mentioning that the default is disabled.

Fixed that, lets see how that impacts things :)

That is a lot less disks than I expect, hopefully this is just a cable/card reseating issue

Bugger the SATA card does not appear to be working since I installed the new 2.5G NIC.

It doesn't work after removing the NIC, or in any other pcie port.

This is weird.

And very annoying.

LovesTha,
@LovesTha@floss.social avatar

But both show up in lspci (so the bios not informing me about them is either a bug, or the actual issue)

LovesTha,
@LovesTha@floss.social avatar

I wonder how much is just that I didn't run updates recently or try rebooting it....

LovesTha,
@LovesTha@floss.social avatar

SATA card's LED's indicate it has links to 5 drives (the correct number)

We'll see what 3 months of updates does

What causes /dev/disk/by-uuid to have 6 devices but /dev/disk/by-path to have 20?
