Re:Tips for more effective fuzz testing with AFL++ on Sunday November 01, 2026 @05:07PM (#50330427)
I think it's mostly a testing thing. Valgrind is a friend a lot of people haven't heard of for c/c++. Setting up good regression tests is an art. Maintaining them is even harder.
It's not about your clock speed, it's about your edge rate. Anyone who's had to lower drive strength or slew rate can tell you that even at 0.0000...1 Hz clock speed, if your routing is trash it can ring to the point of detecting multiple edges or interfering with other signals.

Also some of the issues were on USB lines which hopefully aren't running at 2MHz.

Lastly, since you're coding it, maybe make it pull reference layouts+routing for power supplies from the datasheets. That's step 1 for any real eCAD student.

No explanation of why checking their charge causes a spike in power? To me that's weird but somehow accepted as normal
Re:Major Memory Vendor: We're Basically Sold Out Through 2029 on Wednesday October 28, 2026 @07:15PM (#50282317)
I have 96GB of good RAM. I bought it around this time 3 years ago. Up around 550% when I checked the other day. If a stick dies, it dies. Very sad
Re:Amazon Is Gutting Its AI Division After Sustained Failure on Tuesday October 27, 2026 @01:18PM (#50262460)
Just occurred to me that Amazon seems interestingly positioned relative to the book sourcing thing. I guess that's still not enough.
I think this is true of any trained anything. It's the fish climbing a tree scenario. The teens on Ellen getting laughed at for not knowing how to fold a paper map.

There's infinite front end code to train on. Virtually infinite python and shell scripts too. As I've worked my way away from such domains, the LLM outputs have gotten worse. It just makes sense.

Re:Claude Code slyly adding users' emails to outbound HTTP on Saturday October 24, 2026 @04:12PM (#50224696)
Yeah but that was because it was gently asked to please not. I mean running a firewall/proxy that actually does it.
Re:Claude Code slyly adding users' emails to outbound HTTP on Saturday October 24, 2026 @11:37AM (#50222305)
I think my plan of never letting an LLM access the open Internet wins yet again. Maybe GET requests only, no headers or parameters, ask me for every new domain, and only URLs comprising words/numbers no alphanumerics. Maybe. But it seems trivial to allow for a prompt injected attack vector either way
What's great about this is the are 2 ways to read this:

1. Ukraine is in an offensive position

2. Ukraine is in a defensive position and thus it was indeed Musk

To me these are both very dumb stances. Lose lose statement

I don't see where it says this is the final major update?
Re:Tinder Reverse Engineered on Wednesday October 21, 2026 @07:18PM (#50188984)
We've suspected there was some type of elo ranking for years. But this video is nothing. No sources, no source code, no reproducibility. Pun intended.
Why would you tell it is any persona? Is this the magical "prompt engineering"?
While true, they renamed themselves.
Re:Laptop Based on 6502 CPU on Sunday October 18, 2026 @09:07PM (#50147187)
What an interesting layout for a mobile site. It had the archive and a bunch of other stuff before the post. I thought OP linked something wrong.
Re:16-bit fully functional DIY magnetic core memory on Sunday October 18, 2026 @07:11PM (#50146446)
You can get them up to 16Mb/2MB. Which is 1/128 what NOR flash comes in for a similar price and package. Certainly a trade.

I think MRAM is the future though.

From what I've gathered, and I'm still feeling like I'm missing something, most people don't seem to be doing that. They seem to pass the binary in, say to decompile it, and out the other side is something that looks similar but not exact. https://youtu.be/qFEuYUfauNY .

On the recent WAN show LTT said they tried the recent Photoshop clones and they were buggy, feature missing messes. If they were truly reverse engineer decompiles (minus needing a subscription) they would work just as well. But they don't so they're not.

Re:Gen Z Is the First Generation Dumber Than Their Parents on Sunday October 18, 2026 @10:39AM (#50141510)
> half of it is spent staring at a screen

That's what I was referring to. Not the Gen Z stare.

Re:Gen Z Is the First Generation Dumber Than Their Parents on Sunday October 18, 2026 @10:16AM (#50141290)
I can't speak for others, but I do know that my screen time is filled with this news feed and engineering or other STEM videos. I could never study, it just didn't work for me. But I have a good memory so watching videos tangential to my field helped. I ended up with straight As in my last years of uni, supported by 40+ hours/week of YouTube. Still not sure if that's accounting for 2x speed.

There's a lot of nuance to this. They should consider what we're "staring" at. Is it AI slop content like our parents seem to enjoy? Or more than that? Likewise for social media: maybe consider why in a society where it's prohibitively expensive to do anything and there's a loss of third spaces people are turning to online connections. And beyond that, connections to people from different backgrounds and locations. I can talk to somebody from the other side of the planet online without effort. We can learn of eachothers' hardships and experiences instantly. I think this got shown very well when rednote happened and American + Chinese teens/young adults mixed together en masse for the first time.

Re:Microsoft Surface Laptop Ultra 128GB Review on Sunday October 18, 2026 @09:38AM (#50141011)
That's basically what Linus said on the recent WAN show. People saw the launch announcement a while back, went "ok cool thing ya got. I don't care" and the was the end of that. People cared more about the magnetic usb-c than the product itself.

(Their review apparently performed pretty terribly relative to other videos they had at that time)

Re:Fun Extending the C Preprocessor on Sunday October 18, 2026 @09:30AM (#50140952)
But that repo says it's effortful for the preprocessor and you can see in the code it's a recursion limited but what's in the file. If you had, maybe, a few thousand register definitions in an embedded system, that won't do it.
Re:Laser Fault Injection on a Budget: RP2350 Edition on Saturday October 17, 2026 @10:04PM (#50137139)
I have yet to see that happen on any of the 7 financial apps I use. But if it does, I'll just reevaluate where I keep my money.
Re:Laser Fault Injection on a Budget: RP2350 Edition on Saturday October 17, 2026 @09:12PM (#50136849)
And the best part? Instead of managing all my finance apps (bank, credit card, retirement, mortgage, etc), I just uninstalled them and go to the mobile site. It's not down for maintenance like my checking account app. It doesn't yell at me to update it like my credit card app. It doesn't prevent screenshots. They remember my login honestly more than the apps do.

Re:Microsoft Teams is a red flag on Saturday October 17, 2026 @02:19PM (#50133598)
I think it's gotten a lot better over recent years but in just the past week we had:

A meeting where 2 people somehow weren't able to join. Even after "restarting". One dialed in by phone, the other gave up.

It chose I guess a dock's microphone over a headset mic. Honestly having some kind of tiny local speech recognition model that would say "get you're really quiet/far away/muffled" would be a godsend. That's user error but still. They have the technology.

There's also the problem that it doesn't remember layout preferences so every meeting I have to focus the content, which still doesn't show it full screen.

And unlike discord there's no option for smooth video so good luck.

Also they removed the Linux native app.

You can try --dir-diff btw. It's not exactly the same but it gets pretty close
Re:Oldest shipwreck found off coast of Turkey on Saturday October 17, 2026 @06:57AM (#50129929)
It says they carried spares. Who's to say they weren't carrying 4, came across rough seas, tossed everything non essential overboard, and carried on their merry way?

My point is that there are other reasonable explanations for why that stuff was there and it seems odd to consider 0 of them or consider but not explain why they were invalidated by the experts.

Re:Gnome OS Preview on Friday October 16, 2026 @10:05PM (#50127168)
One of the open source excels said this for adding 3d graphs. I found that forum post a few times over the years. I guess they finally added it but yeah there is a lot of that in open source
Re:Gnome OS Preview on Friday October 16, 2026 @10:03PM (#50127154)
I even tried browsing their website and I still can't find out what it is. The blog post is just about this preview release. The about section is about the entirety of gnome.
Re:Oldest shipwreck found off coast of Turkey on Wednesday October 14, 2026 @10:01PM (#50098236)
I'm sure there are reasons for not explaining why I'm wrong but I question if this could have been the movement of antiques (such that the wreck is much newer than the cargo) or dumped overboard for some reason. All I see is they found really old clay pots.
I don't think I've ever seen an article here of that happening? I wouldn't be surprised if it goes but I think showing the effects now instead of in 5 years is helpful.
