Linux@programming.dev•A Surprisingly Common Mistake Involving Wildcards & The Find Command
22·5 days agoBasic habit to get into:
If you’re contemplating doing something destructive, do a dry-run first.
In this case, remove the
-deleteflag, run the command and see what you get.A good approach is to build a command step by step and test your assumptions each iteration.
Things might take a few moments longer, but one day it’s going to save your bacon.
As for unexpected globbing, learn the difference between quoted and unquoted, and single versus double quotes.

At the rate Microsoft is going, by the time we set up a community on Mars, everyone will have migrated to Linux 😁

Fediverse@lemmy.world•FR#168 – LLMs Join The FediverseEnglish
31·9 days agoLet me ask you this.
If the LLM instance doesn’t talk to anyone, you’re right, but there seems little point in building an instance that talks to nobody.
This leaves us with an instance that does talk to other instances, presumably responding to posts, making its own and subscribing to communities. This already costs money for each “touched” instance.
At that point the administrator of an instance that doesn’t want to federated with the LLM instance, has to defederate from it, updating their instance and then still getting access requests from the LLM instance when it attempts to do the reply, post, community thing as described before.
Even us discussing the phenomenon right now takes server resources across the fediverse.
In other words, as I said, there is always a cost to everyone.

Fediverse@lemmy.world•FR#168 – LLMs Join The FediverseEnglish
41·10 days agoI understand.
My point didn’t state that all instances would be affected equally, just that there’s an effect everywhere.

You don’t need to go to Mars to deal with timezones … plenty of people right here who have absolutely no idea that half the planet is dark at any one time and still schedule global events in their colloquial timezone rather than UTC.

Selfhosted@lemmy.world•[META] Should AI disclosure tags [AI], [NOT AI] be mandated when sharing projects?English
173·12 days agoI think that unless you have some way to enforce accuracy, it’s meaningless and AFAIK automatic detection tools are no better than chance and to my knowledge, getting worse.
An AI bot operator isn’t going to tag their material as [AI], more likely than not they’d attempt to use [NOT AI].
I’d also point out that while lemmy doesn’t (yet) support hashtags, any “tagging” would probably benefit from using the existing method using a #tag.
Ultimately, you need to ask yourself, is undeclared AI that goes undetected by the community a problem, or the new “normal”?
I’ll note that I’m not a proponent of Assumed Intelligence and think that when the bubble bursts we’re going to be in a world of hurt, but with a little luck the billionaires will have lost their shirts in the process.

Privacy@programming.dev•VPNs Promised Privacy. Here's How Several Got Caught Lying

Programming@programming.dev•The Full-Source Bootstrap: Building from source all the way down (adressing Ken Thompsons "Trusting Trust" problem)
6·20 days agoWhile reproducible builds are a good thing, for a bunch of reasons the whole stack is built on top of someone else’s microcode running on someone’s CPU, running someone’s BIOS, etc.
During an Linux Conf in Australia I attended a talk discussing the chain of trust and the point was made that when you buy something from a manufacturer, it is assumed that it comes to you unaltered, but the question is, how would you know?
In other words, you need to trust something somewhere and build on that.
If you’d like to see a working example of a backdoored compiler, because to compile something, you need to also trust your compiler, here’s a good discussion and show and tell:

Programming@programming.dev•We made 75 private repos public on a timer. The internet noticed in 6 minutes.
24·22 days agoThere’s hardly any cost to a bot operator, malicious , opportunistic or legitimate, to hit your end-point, so once they found a reason to hit it, hitting it a million more times costs cents.
Operators like Meta seem to make it a sport, trying to hit you with multiple parallel requests from multiple sources, across both IPv4 and IPv6 simultaneously, resulting in an effective DDoS for small and medium end point owners and increasing costs significantly for anyone trying fruitlessly to stay ahead of their onslaught.
The malicious traffic by contrast, attempts to sneak in a request with dynamic rate throttling as part of their attempts to stay hidden.
Between these two extremes are the opportunistic operators who hit the same 404 endpoint day after day, hour after hour, minute by minute, for weeks with specific blocks the only remedy.
There are plenty of legitimate bots that quietly go about their business, hitting you every couple of seconds, leaving you alone for long stretches, incrementally crawling, honouring the robots.txt file and generally acting the way a considerate adult might. They’ve been getting lower and lower in numbers over the years.

unixsocks on fediverse @lemmy.blahaj.zone•evil non-unix computer (zx spectrum 48k!)
4·23 days agoI worked for a now long defunct company with half a dozen of each, no idea which revision. My job was to crack and re-enable copy protection to create master tapes for bulk duplication.
I was told (as a teenager) that we had agreements with the copyright holders, but I never saw them. We also had an Orange…an Apple ][ clone, a Sinclair QL and a few Commodore and MSX machines.
My own computer was a VIC-20.

15·23 days agoI’m surprised that the Spectrum didn’t reset when you put your feet up. 😁
For those not familiar, both the ZX81 and Spectrum were notoriously fickle when it came to power supplies … often resetting when you looked at it funny.

Also, nice socks!

Programming@programming.dev•LLMs are eroding my software engineering career and I don't know what to do
77·26 days agoGive it time. My software career is also affected. At the rate they’re spending money at an order of magnitude higher than they’re making. They’ve also all borrowed money from each other. It’s going to collapse in a big heap. Hopefully before it sucks in mum and dad investors.

Privacy@lemmy.dbzer0.com•Apple and Google have been given until September to install software that blocks explicit images on children’s mobile phones or face legislation
2·26 days agoIt’s been years and in my opinion nothing is looking remotely realistic as a primary phone. A de-googled Android phone appears to be the closest contender and I don’t see anything in that space that runs on more than very specific hardware.
Another approach is a dumb phone and a Linux laptop or tablet, but carrying around and charging two or three devices is not my idea of fun.
Note that I’ve been using Debian as my primary workstation since the turn of the century.

I read “OpenOffice” and was very confused too, but eventually my brain caught up. Now I’m just bemused.
