@jeanbaptistemarie Gratuit si tu n'utilises pas l'API (sinon 0,1 € par facture) #PDP #facturationelectronique

Étant donné le nombre de connaissances impactées par la réforme de la facturation électronique sans rien y comprendre et sans les outils/ressources pour creuser, j'ai préparé un petit guide simple et rapide à leur intention.
Du coup autant en faire profiter tout le monde. Vous avez une petite/micro entreprise et savez pas quoi faire pour cette réforme ? C'est par là !

QBone now has a web interface and a DELQA Ethernet emulation. 2.11BSD happily talks to the internet. #retrocomputing #pdp

Today I have implemented malloc in 76 bytes in #Uxntal .

After fiddling with this all afternoon, I finally have implemented a malloc other than the simple "bump pointer allocator" I was using.

I'll work on mfree, but that will be for tomorrow.

I changed the unit size to byte instead of 64 bytes because there is no MMU expecting it in 64 bytes in #Uxn as it was in the PDP, so it makes no sense in Uxn? might bite me later.

Catmon was indispensable.

Was going through my bookmarks for PDP-8 documentation stuff and found that dustyoldcomputers.com, which hosted a bunch of documents and software, is now just a domain squatter page 🙁

Illustration: AI whose internal logic no one understands — a neural black box optimised without awareness of what it does. Counter-movement: deproletarianisation, co-individuation with the machine rather than dependence upon it.

RBACX — что изменилось за полгода: от простого RBAC/ABAC до ReBAC с ИИ-генерацией политик

Полгода назад написал первую статью про RBACX — RBAC/ABAC-движок авторизации для Python. С тех пор вышло 25+ релизов, и библиотека стала заметно мощнее: добавил ReBAC с поддержкой OpenFGA и SpiceDB, пакетную проверку прав, ИИ-генерацию политик из OpenAPI-схемы, Redis-кэш, async Django, шортхэнд для ролей и закрыл три security-бага. Рассказываю что, зачем и как это вообще делается в одного.

We have tested UNIX Fourth Edition with SIMH v3.12-5, and it worked!

I wrote a version for Ken Olsen too. #PDP

Last year, I drew a map of the ARPANET for an event featuring retro and vintage computing. It is based on various previously published maps from 1981, but has been redrawn using a vector graphics software. In addition, I marked computers with DEC PDP-10, PDP-11, and VAX architecture to show their role in the early Internet (there were PiDPs and some descriptions about them as exhibits). It was printed as a DIN A1 poster. Here is the result as a 4k JPEG file. #PDP #PDP11 #arpa #vintagecomputing

OTD 1975, Digital announces the #PDP-11/70.
With up to 4 Megabytes(!) of memory.

Princeton's PDP-11/45 had 80K bytes of memory. Ran UNIX just fine.

DEC. История в лицах. PDP-1 (I)

Памяти Кеннета Олсена, родившегося в этот день ровно 100 лет назад Уже глубоко за полночь 1 декабря 1959 года, а именно в 1:30, едва Лоис Андерсон уложила спать третьего, младшего ребенка в семье, раздался телефонный звонок. Из отеля «Статлер Хилтон» в Бостоне Харлан Андерсон позвонил супруге, предупредив о том, что не сможет приехать ночевать домой: прототип PDP-1, исправно работавший в стенах DEC, по известному закону подлости отказывался работать в выставочном зале. До открытия компьютерной конференции оставалось менее восьми часов...

Chats from a #pdp group pops up on Facebook from time to time. Fascinating stuff. I vaguely remember seeing one in 90s, but it was already a museum piece just collecting dust.

Let me add that in this context, Operating System Programmer is akin to a hero in an ancient Greek myth.
