Самая маленькая прошивка (MBR)

В этом тексте я написал про то как написать крохотный, но очень полезный загрузчик. В программировании на STM32 бывает нужно сделать так, чтобы загрузчик оказался не в начале Flash памяти а в конце. Поэтому надо написать отдельную крохотную прошивку первичного загрузчика, которая просто при старте передает управление на другой адрес в физической памяти. Такие прошивки я называю MBR (Master Boot record).

It seems, FreeBSD can't BIOS-boot boxes with too many drives. Is this a known issue in the FreeBSD bootloader? I kinda have to "hide" drives from the BIOS in order to make FreeBSD boot. Trying to boot with 36 disks looks like this: https://ln.tc/s/20260409-105240_2026-04-09-105233_786x456_scrot.png #FreeBSD #bootloader

“Microsoft terminated the #account I have used for years to sign #Windows #drivers and the #bootloader,” Mounir Idrassi posted on #Sourceforge, explaining their absence over the past few months.

una parziale buona notizia personale che magari può interessare chi ha problemi con il proprio cellulare.
Ho resuscitato il mio #smartphone in autonomia (dopo che due centri di assistenza mi avevano consigliato di buttarlo). Ovviamente l'aiuto di vari video su youtube e documentazioni varie è stato fondamentale. Questo mi ha permesso di farmi una cultura sull'argomento. Termini come #bootloader, #recovery, #brom, #rom personalizzate, #flash tool, ecc. erano per me sconosciuti fino a poco più di due mesi fa.
Il fatto che sia parziale è dovuto al fatto che, al momento, sono riuscito "solo" (ma per me già così è stata un'impresa) ad installare #LineageOS versione 18.1 #vanilla, ossia completamente senza app #google di mezzo. Come scoperto grazie a @francommit, LineageOS è comunque Android seppur #opensource e senza google. Al momento non ho trovato altri sistemi operativi compatibili con il mio telefono. E' comunque un modo per discostarsi un po' di più dalle bigtech (in particolare google) nella propria vita digitale.

Just a thought about the #future of #android .

It is driven by a US company, and the US become more authoritarian.

For me, it seems like a company mindset changing from liberty to gatekeeping.

They kill #sideloading, next they might close the #bootloader . Or perhaps stop contributing to #aosp .

So I am thinking: why should I put more of my free time into #android #apps ?

Likely, things will get even more worse over time.

Would it not be a better choice to move to where real #freedom is, like native #linux apps, or native #java ?

Perhaps native #linux will get mature on mobile devices one day.

Any thoughts on this?
