These are neat. Thanks for posting.
How common are the hardware displays that support these in real life?
The rise and rise of OLEDs seems to make these kinds of displays "so old fashioned", but if the display needs to only display monochrome textual information, these displays would reduce risk, possible points of failure (due to reduced complexity/connections).
These kinds of displays probably are cheaper? ..though OLEDs certainly have economies of scale on their side...
Please comment if any of the above fits with some known devices?
...On the artistic side, this font looks great and could be super useful for building soft prototypes of devices... Which kind of loops back to the reason this font was released is because these devices are still perhaps quite well used?
I wouldn't use 14 segment fonts for real hardware. I find these fonts extremely ugly. Many characters are total abominations and it all feels like a hack.
If you need mostly numbers and only some very basic additional info, I think the classic 7 segment display is fine to display something like On/OFF, Hot, C/F etc.
For better text capabilities there are character displays which don't need many µController pins and usually allow creation of some custom symbols. [1]
Having a fully custom LCD prototype created and maybe having something like 100 pieces manufactured is surprisingly cheap. [2]
And then there's the modern OLED displays of course with full graphics support and colors, but these are usually more expensive and more difficult to drive.
Uses today? I just got a Giant Grill Gauge and it uses the older style lcd and segmented display. Temp/humidity monitors still use them too. Really comes down to being very easy to integrate and power usage. Being able to run them for months or years even on small batteries is huge.
Great that you had the time to be curious and dig into what was going on. QEMU is quite an amazing tool.
I'm kind of surprised there isn't a fairly robust kernel test around this issue, since it locks the machine down and I think the fix was to prevent a stuck CPU last time as well?
It's also vaguely surprising that this hasn't been encountered more often, particularly by the https://news.ycombinator.com/user?id=everlier talking in links to this HN post about "20-30 containers" running simultaneously and occasionally locking up the machine.
If you're still thinking about the bug a little, you could look over how other kernel tests work and implement a failing test around it....?
I imagine the tests have some way of detecting a locked up kernel... I don't know exactly how they'd do it, but they probably have a technique. Most likely since the kernel is literally in a loop it won't respond to anything.. so starting any process, something as simple as creating any process, even one as simple as printing "Hello World!!" would fail and indicate the machine is locked.
Perhaps this is one of those cases where something like UserModeLinux would allow a test to be easily put together, rather than spawning complete VMs via some kind of VM software. Again, would be interesting to know what Linux does with this kind of test.
It could be a good, relatively portable gas peaker. Though I would have thought batteries might be a better step for peak load management?
This might sit somewhere between peak load and base load?
Since the CO/CO2 exhaust from this turbine should be able to be captured fairly well, would it be possible to capture it on the spot into tanks of some kind? There are most probably some large thermal issues to deal with here..
I also wonder about the MIT COF-99 (https://www.scientificamerican.com/article/exotic-powder-pul...) that eats up CO2 very efficiently.
If simply CH4 is being passed to the turbine, is the water generated from the combustion being captured anywhere?
What about the sound characteristics of this beasty? There are cases in the US of people noticing the new AI data centre fans whining at all hours.
There'll be an engineer/physicist out there somewhere who'll come up with a generally efficient way to move heat around (Graphene ?) and he'll start a multi-billion dollar business.
Nothing fancy. Postshot does need a nvidia card though, I have a 3060Ti. A single insect, with around 5 million splats takes about 3 hours to train in high quality.
Thanks! Goblins is actually our main project and Hoot is the side project so we can deploy it on the web. Scheme is a really nice language and when you add in some modern features you can do some pretty neat things!
