Several years ago, a street medic described a system like this and wanted to know if it could be built.
https://hackaday.com/2022/09/08/the-tak-ecosystem-military-coordination-goes-open-source/
Back then there was just no way to make it happen. Hardware was too expensive. We couldn't really ever get it cheap enough, per medic, to deploy. Best I could put together was a bunch of burner phones.
But now it's starting to really make sense. LoRa is cheap, and possibly cheaper in bulk. And it wouldn't be necessary to build everything since ATAK-CIV exists and has several open source implementations. It can even tie in to drones (which are illegal to bring to protests in at least a few states).
This has a lot of potential applications for street medic coordination, protest marshal coordination, and for airsoft teams...

Open source isn’t free. We’re just not paying for it: Who maintains the maintainers?
A lot of things don’t add up in the world of software. The skills gap remains stubbornly wide, with IT and data skills the hardest to recruit for five consecutive years. Yet, at the same time, entry level roles are declining as employers redeploy existing employees rather than hiring new ones.

As I've said, I want to make a version of my "My Tech"-site, but this time not for country of Origin, but Open vs. Closed Source.
But before I start, I need two emojis for both. Any ideas? I really think the emojis are important and they should be easily recognizable. What can I use for #OpenSource and what for
An interesting juxtaposition of 2 articles in Apple News. One’s about the dev who added code to an open source app he’d developed, that would delete code in an app that was vibe coded. He’s getting death threats.
Other one’s about a guy suing an employer for not accommodating his phobia of rainbow flags and “trans pronouns” (sic). He claimed to be a devout Catholic and feared all those “gay” symbols were a threat to his soul.
My main gripe with “AI coding” is that people present it in highly emotional terms as a fait accompli that will “change everything” instead of it being just another tool (that is one of many) to make software.
Like I saw a SERIOUS post today (not on here) from a tech guy I previously respected that was basically like a 90s infomercial with black and white video of working on a computer (labeled “without AI”) and then over-saturated footage of chilling in the pool or whatever shit (labeled “with AI”).
Not to mention there’s a constant barrage of “enjoy being poor” type bullshit.
This is abusive behavior; it’s emotional manipulation and gaslighting.
It’s cringe, as the kids would say.
I think the underlying LLM technology has use cases that are genuinely useful, for example when making explorative software prototypes, both for backend and frontend stuff.
But it's like a hammer. Useful for nails, useless for anything else.
And you got to ask where the hammer is coming from. Was it made with stolen metal? Forged by exploitative labor? Locked away in a data center so you can only rent the hammer by the hour from some business trying to do a bait and switch?
I'm hoping that the AI landlord industry dies eventually (signs point to this as they won't be able to fulfill the obligations to their investors) and people use locally-run stuff, ethically with open source models (without stolen stuff) and without ridiculous environmental impact in the future.
This has been on my mind for *weeks*. I've been saying for a long time that it's possible to have an AI that only uses consensually-gathered content, is open source open weights, runs on your own machine, and is designed to empower creators instead of exploit them. Well, we've finally got one. https://www.

Since his first years as a top player, Jannik Sinner has long had one major weakness.
The hotter it is, the more vulnerable he becomes.
It nearly toppled him at January’s Australian Open, before Novak Djokovic did the job instead.
On Thursday, with temperatures climbing toward the 90s at Roland Garros, Sinner could not endure.
In the second round of the French Open, the world No. 1 fell victim to Juan Manuel Cerúndolo of Argentina, the world No. 56.

I spend a lot of effort on noise reduction. Turning off alerts, reducing the size of (especially redundant) messages I don't really need to see—that kind of stuff.
It's REALLY disruptive when software I use decides to get rid of those filters. Like not even just turning the noise back on, but fully removing my ability to even filter things.
I regularly mourn the wonderful period of time when software worked for us. (This *is* open source, but maintaining a fork is more wo…

What if we're making the wrong bet about progress?
Just watched someone crack open a million-year-old fossil like it was nothing. Made me think: we open ancient things believing we'll get the most value NOW. Not later.
Same with AI. We're betting progress will speed up AND slow down at the same time.
Weird, right?

RE: https://dice.camp/@realms/116459545804565917
I'd argue that "AI"-based development creates a bigger attack surface on closed source/proprietary software than open source software:
1. It's more likely that internal software development uses LLMs as they're most affordable to companies; leaving them more vulnerable to prompt injection and other types of attacks targeting LLM use.
2. It's more likely that internal commits aren't vetted as much (or even purely vibe-coded) as ones in open source projects.
3. It's more likely that attacks on open source projects are discovered quicker.
Also a reminder that the "Mythos" thing—like all the other doomerist things coming out of "AI" companies—is a marketing stunt to get Anthropic free press coverage.

Are governments properly supporting the digital commons? Many adopt open source software but don't fund the upstream projects that maintain it. This amplifies a "tragedy of the commons" rather than being part of the solution. Governments have historically invented ways to shape the playing field - patents, public universities, copyright, taxes ... They can do it again!

It feels like the open source world is fracturing. It used to be if we wanted alternatives to commercial software we could look to open source, but so much of open source software today is using AI.
Sure, some maintainers are saying "I only use it to speed things up, I still review all code before it gets added." but for lots of folks that's not good enough, and they draw a hard line at the use of any AI.
