    As the dust settles the warriors of the north emerge from their first skirmish. Most of the enemy has been routed but no decisive victory achieved. The vikings will have to regroup and prepare for the coming battle for the coveted DefCon tickets.

    Here is my massive lib db (for ctfs/wargames/blind pwns etc.). It consists of thousands of libs across over a dozen Linux distributions and architectures spanning the last 20 years. It indexes symbols & gadgets (including one gadgets AKA magic gadgets).

    So, what's the least shitty self-hosted alternative to Google Docs? I.e. real-time collaborative text editor supporting multiple documents some basic text formatting (headers, lists, tables, images) and some kind of authentication.

    The NorseCode Saga Seven tribes gathered their blood-thirsty warriors; From Midgård the highly skilled sploiters of Ragnarök; From Asgård, Vanaheim and Jotunheim the fearsome hackers of Odin; From Niflheim, Nidavellir and Hel the wildest beserkers the world had ever seen.

    Google in -15. Got told beforehand that it would involve programming questions and I can use my choice of Java (rather not) or C++ (yes please) for this. First interviewer: "I don't know C++ so you'll have to do it in Java". TBF the other interviews were fine and feedback fair.

    Life working at a healthcare company: colleague (who is on a vacation in the mountains) posts an x-ray image of his shoulder with the text "Find the fracture" and a 33 message Slack thread with both doctors and software engineers immediately follows.

    Both in 9th grade: 1. Sold homemade wine during class. Almost got my grade lowered. 2. Usured money to classmates for a 100% interest per day and had a collector beat up anyone who didn't pay. Financed all my candy needs that semester.

    Don't have one. Would kind of want to one day but that's just because I'm a bit vain and in general is no indicator of skill. Would even go so far to say that some CVEs are a minus in my book since some are absolute BS and you should feel bad for wasting people's time with them.

    Yesterday I set up a server for the first time and while I haven't had time to form a strong opinion about the software itself I want to give huge props to the excellent documentation and installation instructions. Literally not a single thing went unanswered. Respect
