It's the LTS5 from Dragino, a LoRa touchscreen: https://docs.dragino.com/docs/LoRaWAN-End-Node/lora-modules-.... And for the record, I'm extremely happy with all their other products, which are all open-firmware, open-hardware, etc. and excellent quality. Plus they're super responsive. It's just this particular product which has this weird issue.

I lost a good two hours the other day on an insufficiently documented device, looking for a way to flash a new firmware onto it.

dmesg was absolutely silent about it when I plugged in or out my C-C USB cable although the device switched on when I was using a simple charger instead. I opened it up to see if there was a special switch or something to put it in firmware flashing mode, to no avail. The little documentation I had only mentioned using one of the USB port.

In the end, out of ideas, I switched cables (even though I knew my cable was perfectly fine). As soon as I plugged in a A-C USB cables, everything worked immediately...

To predict anything on the ground, you have to predict air temperature, humidity, wind speed and direction etc. for the entire troposphere. The output of the models in altitude are as relevant to the meteorologists as the output on the ground for manual expert analysis.

A few years ago, a dispute between Kosovo and Serbia caused the entire European grid to drift away from 50.000Hz down to 49.996Hz. Millions of microwave clocks across the continent ended up 6 minutes late: https://hackaday.com/2018/03/09/europe-loses-six-minutes-due....

I was about to comment that exactly. If you computer is never switched off, your encryption is permanently bypassed.

That's a blast from the past. I remember repairing my main install from a minimal Knoppix on my 1GB USB drive... Good old times.

Lightning is electricity that goes through hundreds of meters or even kilometers of air (supposedly a good electrical insulator) to reach the ground, it's not above travelling through electrical lines the opposite way they're intended to be used.

Assuming they are independent events, OP is not more nor less likely to win the lottery now that before running in the collision. I actually have more question if you claim the events in question are NOT independent!

New comment by lgeorget in "Ask HN: Why Databases Instead of Filesystem?"

That's orthogonal to the discussion, I think, you can also mount and access remote filesystems from any program as if it was a local filesystem.

More of a sidenote than an answer but a database system can be faster than using the disk directly: https://sqlite.org/fasterthanfs.html#approx.

It turns out having a defined abstraction like a database makes things faster than having to rely on a rawer interface like filesystems because you can then reduce the number of system calls and context switches necessary. If you wanted to optimize that in your own code rather than relying on a database, you'd end up reinventing a database system of sorts, when (probably) better solutions already exist.

lgeorget — Thu, 09 Apr 2026 14:31:27 +0000

Yeah that's also how I work: be strict to yourself, indulgent to other, I feel this is the best strategy to get along. Obviously, the downside is the tragedy of the commons: the few bad people abusing the leniency of the rest and getting away with it, like people showing up late because "they hate waiting".

I'm also neither. But I'm also very good at lying to myself, so who knows? (not me)

New comment by lgeorget in "What does " 2>&1 " mean?"

lgeorget — Fri, 27 Feb 2026 12:36:13 +0000

It reminds me of this answer I made some years ago: https://unix.stackexchange.com/a/138046

The question was how to remember it's "2>&1" and not "2&>1". If you think of "&1" as the address/destination of, the syntax is quite natural.

I learned about it the hard way, ahah. Now I create intermediary planes for all distances and I extrude planes always with respect to those.

How does enclosing the lamp in reflective material help with the energy efficiency? Isn't the infrared radiation emitted anyway? Doesn't that make the lamp overheat?

Yes it's so strange, like bad and unreadable pseudocode.

I could see myself coding in Latin though: https://github.com/pianoman911/ferrugo. Something about the prepositions tickles my brain the right way.

New comment by lgeorget in "Tesla said it didn't have key data in a fatal crash, then a hacker found it"

lgeorget — Fri, 29 Aug 2025 13:07:29 +0000

I guess one charitable way to look at it is that after a crash, external people could get access to the car and its memory, which could potentially expose private data about the owner/driver. And besides private data, if data about the car condition was leaked to the public, it could be made to say anything depending on who presents it and how, so it's safer for the investigation if only appointed experts in the field have access to it.

This is not unlike what happens for flight data recorders after a crash. The raw data is not made public right away, if ever.

I know that's not your point and I'm not saying this to cherry-pick your argument but in case that's particularly relevant to you, Debian Trixie ships with Kicad 9 : https://packages.debian.org/trixie/kicad. If you're stuck with an earlier version, maybe you have a dependency blocking your updates.
