This is one of the craziest #hactivism stories I've ever heard! 
This is the story of D3f4ult from CWA. He was a hacktivist, upset with the state of the way things were, and wanted to make some changes. Changes were made.darknetdiaries.com

Listening to this episode opened my eyes about the crazy world of cyber mercenaries, a part of the #MilitaryIndustrialComplex profiting off of wars.

@AntennaPod surprised me with this cool feature today!
I think Spotify had a similar feature for the songs you listen to, but I haven't been on Spotify for a long time so I don't know what it's called now. But it's cool to see this on a FOSS podcast app like #AntennaPod, and the amazing thing is that they generate it locally on your device so it's privacy friendly 🙂
@ralf_weinert
Yeah, and here's my podcasts if you're interested - fosstodon.org/@futureisfoss/11…

TIL after watching this video that spacetime curvature doesn't actually mean it's bending into the 4th dimension, all this time I thought otherwise 😅

@bignose I can't summon up much enthusiasm for AoC this year. I don't need to:
* Learn a new language
* Learn to program
* Write yet more string parsing code
* Wrestle with algorithms that are vanishingly rare in the real world
* Prove anything, to myself or others
* Invest time/energy I could usefully spend elsewhere
But I'm delighted others enjoy it at least as much as I've enjoyed it in the past. Plus it's a great spectator sport.
This was actually my first year trying out AoC, as a beginner to programming it was kind of a fun learning experience, but being a beginner also means I'll have to stop sometime as the puzzles get harder. Last day's puzzle was a bit too hard for me, maybe today's is better I might give it a try but I certainly won't put any pressure on myself 😄

haha, i also though like this at the beginning, though i thankfully didn't go down that road, but i also spaced out on a silly mistake returning 0 instead of the last value in a utility function…
At least part 2 was trivial from my part 1 solution.
I thought my code is never going to terminate, but after around an hour or so it did, LMAO 🤣
Because I had to refactor the code many times for this one my current iteration doesn't make much sense, so I'll publish it later maybe after doing some cleanup, IDK...... It's all spaghetti code anyway 
Rokosun reshared this.
Update: I've made the code a lot more faster by following a tip by @sotolf. Basically now the program is doing a reverse brute-force by starting at the end point and working its way upwards. So now the code finishes running in about 2 minutes, but if you use the --opt:speed compiler flag in #Nim then it can finish in 20 seconds! For comparison, my previous code took 12 minutes to finish even with the compiler flag on!

I was watching this video by @emilymbender and she made a lot of great points there, highly recommend watching it if you're curious about #AI and the hype around it. I was a bit surprised when she brought up magic 8 ball because I've been jokingly calling chatGPT magic ball in my friend circles, but it's such a great analogy tho 😄

@amin yeah, that's exactly how I'm thinking how can I represent the data, and then how can I get closer to what I want, or functions I need to do what I need. My way is just one way to do it, but it's the one I find the easiest to work with :)
Types are a bit daunting in the beginning but when you do they really help you think, and let's the compiler help you not do a quite big group of errors :)

Sidedoor - Cellphones Rock

One fascinating fact I heard on this #podcast episode:
> If everyone in the country use their phone one year longer on average, it'd be the same as taking 636,000 gasoline powered cars off the road.
The episode mainly talks about the precious minerals in our phones and how they're extracted from rocks formed millions of years ago, not only do we have a limited supply of these minerals but it also can't be recycled properly.
Cellphones put the power of the world at our fingertips. With the touch of a finger, you can instantly connect with your doctor, have food delivered to your office or simply obliterate your niece at Words with Friends.play.prx.org

Unsung Science: The Man Who Invented QR Codes
In 1994, Masahiro Hara got tired of having to scan six or seven barcodes on every box of Toyota car-parts that zoomed past him on the assembly line. He wondered why the standard barcode from the 70s was still used...Why couldn’t someone invent a barcode that used two dimensions instead of one that could work from any angle or distance, even even if it got smudged or torn?
And so, studying a game of "Go", he dreamed up what we now know as the QR Code — the square barcode you scan with your phone. It shows up on restaurant menus, billboards, magazine ads — even tattoos and gravestones. But even that, says Hara-san, is only the beginning.

De Fiets is Niets
99percentinvisible.org/episode…
Today the Netherlands has a reputation as a kind of bicycling paradise. Dutch people own more bicycles per capita than any other place in the world. The country has more than 20,000 miles of dedicated cycling paths. International policymakers make pilgrimages to the Netherlands to learn how to create good bike infrastructure.
But none of that was inevitable. It wasn't something that magically emerged from Dutch culture.
In fact, in the 1960s and 70s, it looked like the Netherlands would follow the same path as the United States. The Dutch had fallen in love with cars and they were rebuilding their cities to make room for them. It was only because of a multi-decade pro-cycling movement that cars didn't take over the country entirely.

in reply to Rokosun • • •And depending on where you live, the police might be able to force you to give them your fingerprints, but not a password.
But I fully agree that scrambled PIN pads should be more common, that helps a lot against someone just glancing over.

in reply to Nils • • •P.S. I very much agree that it comes down to your own personal threat model. E.g. I haven't bothered having a password lock on my phone since the dawn of smart phones, and very grateful for all the time and hassle that saves me. But then I hardly ever use a phone, and don't have anything critical like email connected to it, so the risks involved are rather less that for most people

in reply to Rokosun • • •It seems only somewhat more secure than gesture unlock.
It might trip-up video analyzis or surveillance unfamiliar with it, but two captures seem like enough to have a very high probability of identifying the commonality. Depending on user behavior, a single observation could be enough.
The best option, I think, would be some HMD as the sole active display.

Yeah if you got recorded on video and there are multiple instances of it then you might be doomed. Randomly spacing the numbers each time could make it harder maybe, but IDK..... It's not perfect for sure.....

in reply to Rokosun • • •The AOSP-based custom OS GrapheneOS has PIN scrambling, which makes these attacks a bit harder and also improved fingerprint unlock security.
Highly recommend looking into the project because it has many amazing security features on top of AOSP, and is one of the few custom OSes with actual security researchers developing significant improvements.
