↳ In-reply-to » Holy moly, this is a fantastic 37C3 talk about security researchers getting attacked and they reverse-engineer and fully disclose the entire – very advanced – attack. Operation Triangulation: What You Get When Attack iPhones of Researchers Very impressive!

@lyse@lyse.isobeef.org I have read the white papers for MLS before. I have put a lot of thought on how to do it with salty/ratchet. Its a very good tech for ensuring multiple devices can be joined to an encrypted chat. But it is bloody complicated to implement.

↳ In-reply-to » Feedback on why I didn't choose Mattermost (lack of OIDC) · mattermost/mattermost · Discussion -- My discussions/feedback on Mattermost's decision to have certain useful and IMO should be standard features as paid-for features on a per-seat licensed basis. My primary argument is that if you offer a self-host(able) product and require additional features the free version does not have, you should not have to pay for a per-seat license for something you are footing the bill for in terms of Hardware/Compute and Maintenance/Support (havintg to operate it).

@prologic@twtxt.net What I did as a work around for mattermost was hijack the gitlab oauth login with my own auth server.

↳ In-reply-to » man... day17 has been a struggle for me.. i have managed to implement A* but the solve still takes about 2 minutes for me.. not sure how some are able to get it under 10 seconds.

@xuu@txt.sour.is That was one of the horror puzzles where I had to look for help. 🥴 I modelled my solution after this: https://www.youtube.com/watch?v=2pDSooPLLkI

(I can’t explain it better than the video anyway.) It takes a second on my machine and that’s with my own hashmap implementation which is probably not the fastest one.

↳ In-reply-to » @xuu Despite that these AoC math text problems are rather silly in my opinion (reminds me of an exercise in our math book where somebody wanted to carry a railroad rail around an L-shaped corner in the house and the question was how long that rail could be so that it still fits — sure, we've all carried several meter long railroad rails in our houses by ourselves numerous times…), these algorithms are really neat!

@lyse@lyse.isobeef.org They sure are silly at times. :-) You really have to combine this event with something else, like learning a new language. Otherwise it gets boring real quick.

What I absolutely love about AoC is that it’s – indeed – a bit like school. 😅 The problems are well-defined, the inputs are well-defined, and there is a definite answer. It’s either right or wrong – period. Compared to real life and work, I welcome this very much. 🤣

↳ In-reply-to » But when you do take the time to analyze / reverse-engineer this puzzle, then it’s really cool. Might be my favorite one so far. 😃

@movq@www.uninformativ.de So.. i eventually made it to the end on this one.. was able to reuse code from days 8 and 9!

↳ In-reply-to » I fell with a stupid e-scooter and have been waiting at the hospital now for more than three hours. Not worth it. I almost broke my left elbow and right hand wrist. Got lucky because I was wearing a helmet. Not going to try that again. The wheels slipped on the wet zebra crossing paint in a turn.

@johanbove@johanbove.info hope all goes well. my Buddy did the same but alcohol was involved so that falls on him.

↳ In-reply-to » Today’s AoC puzzle is a very simple problem on modern machines, but quite tricky for me: It involves a number that doesn’t fit into 32 bits. 🤔 I wonder if/how I can manage to port this beast to DOS. (I once wrote a “big int” library myself, but that was ages ago and I hardly remember it anymore.)

@movq@www.uninformativ.de it shouldn’t need a full bignum implementation right? Just some left and right shifts for the sq/sqrt and carry for the addition right?

↳ In-reply-to » It is a pleasure to work with the help system of Borland’s Turbo C++ 3.0 on DOS. The descriptions are clear and concise. There are short and simple examples. Pretty much every help page is cross-refenced and those links can be clicked.

@eapl.me@eapl.me I have many fond memories of Turbo pascal and Turbo C(++). They really did have a great help system. And debug tools! Its rare for language docs to be as approachable. QBasic was great. As was PHP docs when I first came into web.

↳ In-reply-to » Day 2, Part 1 and Day 2, Part 2 of #AdvenOfCode all done and dusted 😅

@xuu@txt.sour.is Ah, you went with the “scanning” approach as well. I did that, too.

It’s quite surprising to see (imho) how many people on reddit started substituting strings (one becomes 1 etc.). That makes the puzzle much harder by introducing nasty corner cases.

(Maybe I was just lucky this time to pick the correct approach right from the start. 🤣 Or maybe it’s a bit of experience from doing past AoC events …)

↳ In-reply-to » @slashdot I feel like this is a bit of a common pattern? Company builds an awesome product, makes it free for a lot of users, then create additional features and paid plans, makes a tonne of money. But then later decide they need to make more money, so focus on converting the free users to paid users. Hmmm 🤔 Surely this can't be the only viable business model? 🤔

Obligatory Twtxt post: I love how I can simply use a terminal window and some very basic tools (echo, scp, ssh) to publish thoughts, as they pop up, onto the Internet in a structured way, that can be found and perhaps even appreciated.

@prologic@twtxt.net its not.. There are going to be 1000s of copy cat apps built on AI. And they will all die out when the companies that have the AI platforms copy them. It happened all the time with windows and mac os. And iphone.. Like flashlight and sound recorder apps.

@prologic@twtxt.net the new product was GPTs. A way to create tailored bots for specific use cases. https://openai.com/blog/introducing-gpts (fun fact: I did an internal hackathon where we made something like this for $work onboarding. And I won a prize!)

The competed project is poe https://quorablog.quora.com/Introducing-creator-monetization-for-Poe which is basically the same idea. Make a AI bot tailored to a specific domain of knowledge. And monitize it.

The timing fits very well as openAI announced it just a few weeks ago.

@prologic@twtxt.net the going theory is that openAI announced a new product that pretty much blew up the project of one of the board members. So that board member got 3 others to vote to fire Sam.
