I begynnelsen var Arpanet. Det var början på det vi idag kallar internet. Nätverket skapades som ett projekt inom Advanced Research Projects Agency (ARPA) som är en del av USAs försvardepartement. Idag heter myndigheten DARPA.

〔インターネットの先駆けである〕ARPANETは軍事利用目的で作られたという神話を信じる人たちに伝えたい開発者の想い（Zenn, 2025-07-09）

>> インターネットの祖先にあたる Arpanet 開発の技術者たちにとっての最大のモチベーションは「高価な計算機資源の共有」だった

>> ARPANET が ARPA〔Advanced Research Projects Agency; 高等研究計画局〕 という軍事技術を研究する機関から生まれた… これは正しい

>> けれど、だから軍事利用を目的に ARPANET が開発されたというのは間違っている

>> ARPANET は、この ARPA のプロジェクトの一つだった。けれど、軍事利用が目的だったわけではない…

Il 14 gennaio qualcuno ha staccato la spina a Telnet. Il traffico globale è crollato del 65% in un'ora, sei giorni prima che il mondo sapesse perché. Taiwan ha filtrato il 77%, l'India il 70%, il Giappone il 65%.

Un protocollo nato nel 1969, una vulnerabilità nascosta per 11 anni, 52 IP da 16 paesi che hanno tentato l'exploit, e un mistero che sembra un thriller. La storia completa nel nuovo episodio del buongiornirondirondello.

I'd previously been under the impression that the details of the #ARPANET IMP-to-IMP protocol (as opposed to the well documented #1822protocol for Host-to-IMP communications) had been lost, but it turns out that's not the case. In fact, it appears that in the last 15 years copies of multiple versions of the full source code for the #IMP software have been recovered by using OCR on hard copies. Much more information at https://walden-family.com/impcode/. I don't know the extent that the protocol itself has been reverse engineered from the code.

I love that this was written using #Midas, a programming language which was developed by a hospital. I think I did actually already know that, maybe from https://katiehafner.com/books-new/where-wizards-stay-up-late/ - presumably #BBN just used code they already had from an earlier consulting project.

Anyway - preserve your software projects. I'm sure many of the people doing this in the 60s and 70s didn't realise that what they were doing would be historically significant at the time.

You may have seen a "today in history"-type toot going around that talked about ARPAnet switching to the IP protocol, effectively being the birth of the internet. It was a long time ago.

And it made me realize that the internet per se was only 3 years old when I first experienced it.

Vor 43 Jahren: Wie TCP/IP aus ARPANET das Internet machte
Am 1. Januar 1983 startete ein Protokollwechsel, der das Fundament für das heutige Internet legte. ARPANET stellte schrittweise vom Network Control Program (NCP) auf TCP/IP um.

Happy birthday to the Internet!

On this day in 1983, the ARPANET network officially switched to using the TCP/IP protocol, effectively creating the Internet. https://www.usg.edu/galileo/skills/unit07/internet07_02.phtml
