ran into a bunch of issues compiling grub2 on MinGW, so here's an infodump:

Unsupported TCHAR size - just typedef TCHAR as char, and SIZEOF_TCHAR as 1.

next, error: conflicting types for ‘grub_util_file_sync’; have ‘void(FILE *)’

for some reason it's declared void in grub-core/osdep/windows/hostdisk.c so change it to:

int
grub_util_file_sync (FILE *f)
{
if (fflush (f) != 0)
return -1;
if (!allow_fd_syncs)
return 0;
return fsync (fileno (f));
}

@gsuberland did you write this? I would read it, to learn about how to boot a x86. Never did that.

Vous vous en fichez mais je découvre qu'il y a un résolveur public en Inde (apparemment géré par le registre du .in) et il a une bonne adresse (et elle répond aux ICMP echo).

Comme quoi les adresses IPv6 ne sont pas forcément plus longues et plus dures à mémoriser que les adresses IPv4.

am I the only one completely uninvested in raspberry pi stuff? there always seems to be some fervour about their newest unobtainium SBC doodad and I never quite understand the use-case for the price.

@gsuberland it's not that interesting. It would be cool as a server but the disk performance is abysmally bad, model after model. A two player minetest world using the sqlite backend does not run smooth when the world is on a usb key.

The last model has pcie but not easily available m2 or other mounting board so... Meh.

    Just found out that my dad is having a stroke... on April Fool's day, which is a bad time to do that... not that there's a good time to do that.

    I can't go to the hospital, it's too far away from my house... I'm letting my brother take my car.

    I don't know what to do right now.

    Eek. Apparently liblzma (part of the xz package) has a backdoor in versions 5.6.0 and 5.6.1, causing SSH to be compromised.

    https://www.openwall.com/lists/oss-security/2024/03/29/4

    This might even have been done on purpose by the upstream devs.

    Developing story, please take with a grain of salt.

    The 5.6 versions are somewhat recent, depending on how bleeding edge your distro is you might not be affected.

    @scy Not really assuming anything. But as said "the cat is out of the bag" and it's important to notify people getting info via this channel, much more important than any denial or confirmation from the potential offender.

    I was given one of those 12V, 1.5 watt Harbor Freight solar panels and I think it would be cool to do some kind of solar powered microcontroller project.

    The friend who gave it to me said that the panel is not quite powerful enough power and ESP 32 when Wi-Fi is activated. So, that means either using an Arduino or an esp32 without Wi-Fi turned on, which limits my options.

    I would like to keep it simple so I don't want to deal with batteries and a charging system. Just solar panel and microcontroller

    ST's latest and greatest idea is to sell the same part in the same BGA package in two subtly different pinout variants. The two variants are only distinguished by the last letter of the part number, which is at the end of the flash size and temperature variant section that does not affect the pinout in any other part they make. The package letter of the part number is identical for both variants.

    @jaseg this cpu has sexy power but excuse me, just 64k flash? they expect the os to be loaded in ram from mass storage? That sucks!

    Assembling the trigger crossbar board over lunch.

    Not thrilled with the paste print quality, very inconsistent. the top left corner was way too thick as the board flexed during printing, the middle BGA skipped some pads, and the WLCSP in the bottom right was near perfect.

    These big boards bend too much in my paste fixture, I need to find a way to prevent that before I do any more boards of this scale.

    or the Microchip way:

    present in die revisions: A1 A2 A3 A4 A5 A6 A7

    dudes you know you're supposed to fix bugs in new revisions? or did the bug went undetected in the 6 previous masks?

    The venerable Voyager 1 spacecraft is experiencing another glitch. Instead of sending science and engg. data, it is sending a 0101 bit pattern.

    The problem has been narrowed down to the flight data system (FDS), which is not communicating properly with the telecom unit (TMU). A reboot did not help.

    Stay tuned as NASA engrs work out a fix for this 1970's era computer, which has performed magnificently during its long 46-year journey to the planets and to outer space.

    @AkaSci i guess it will require a full reprogramming to avoid allocating memory in the faulty chip. Do they still have the ability to assemble code for the FDS?

    f4grx,
    @f4grx@chaos.social avatar

    @AkaSci it depends if they have the assembly listing to regenerate the software load or if they need to do binary patching!
