jlarocco··on Anthropic reported diary entry to police, woman faces felony charge
"Assume people can see everything you post on the internet" still applies when using AI. It's not as newsworthy when you put it that way.
jlarocco··on DraftKings is using AI to behaviorally target chronic gamblers
> Do you actually enjoy the smoke in your mouth, burning your eyes and lungs?

TBH I just didn't have those sensations. People wouldn't get hooked if it felt terrible.

My sister still smokes, and every now and then I'll have a few hits of one of hers, and it's great. No doubt I could get hooked again if I wasn't careful.

The silver lining is there's a whole boatload of drugs I never tried (and never will) because I know first hand how easy it is to get addicted.

jlarocco··on DraftKings Is Using AI to Behaviorally Target Chronic Gamblers
As a former smoker (I started and quit twice), I strongly disagree that "Smoking tobacco is an unpleasant sensation."

It's terrible for your health, it's "burning money", it literally makes you stink, it makes you winded walking up stairs, and is generally terrible.

But the little head rush you get starting the day with a coffee and a cigarette feels great.

jlarocco··on 1996 chat room simulator connected to Win95 and System 7 web desktops
I don't know... AOL chat on a 56k modem (IMO) worked better than Teams and Slack and had most of the features.
jlarocco··on Owed a billion dollars in Nvidia stock
I don't blame him for trying, but it seems like a long shot.
jlarocco··on California is chasing wealth that has feet
They can only increase rents as much as the next guy. If you're charging $2500 but next door is $2400, then nobody will rent from you. But if everybody's charging $2500, then that's what people will have to pay.

You're right that some people will get squeezed out, but in high demand markets there are enough people willing to pay that it doesn't matter. The number of properties available for rent in California isn't growing as fast as the total population is growing. Property owners will eat the 5% increase for a while - at least until the existing leases expire - but eventually they'll incorporate that 5% increase into the rent.

That doesn't say you can't do them, though - they just don't take responsibility if doing so fails because of Java somehow.

Basically, it voids the warranty, which you don't really have with Java anyway.

jlarocco··on Excel now supports multiple values in a single cell
Now add 2D lists...
jlarocco··on Microsoft abandons personal AI chatbot race with Copilot reboot
If you have enough money nobody can tell you what you do.
jlarocco··on Ask HN: Who's still keeping a DOS machine up because the business depends on it?
Yeah. Sometimes old hardware forces its hand and causes a big PITA.

I had a job working on VAX/VMS around 2009, but it was actually an emulator running on a PC because they just couldn't find any hardware to fix the VAX. At some point before I joined they had to get a ton of government approvals to use the emulator.

Fortunately they had a project to modernize the whole stack. And it was going to Solaris :-/

But who's selling the land? If everybody has to pay the tax then all of the property owners can increase rental prices by the same amount.
jlarocco··on VSCode's SSH Agent Is Bananas (2025)
The idea that it needs to run an agent on the remote machine to edit files over SSH is itself bananas.
jlarocco··on Meta VR Glasses
And I was pointing out that they are one and the same but the "Facebook" name was so tarnished by their terrible privacy practices they had to change it to save face.

But I guess if people like you are able to ignore that to make yourself feel better about giving your personal information to Zuckerberg's advertising company then anything is possible.

jlarocco··on Meta VR Glasses
> They have Meta accounts now, which are also not Facebook accounts.

How gullible can you be?

jlarocco··on Feds Target AI Critics as "Foreign Agents"
The "increases the risk of extinction" bit is 100% marketing BS that they're spewing to pump up their stock prices and encourage the government to shutout foreign competition (who would use this ability against the USA, of course ).

They've played you like a fiddle.

jlarocco··on Apple has added persistent 'ads' to iOS, and it's driving users crazy
I don't see what point you're trying to make. Those two examples work identically in the OSX terminal.
jlarocco··on Apple has added persistent 'ads' to iOS, and it's driving users crazy
Something to keep in mind is that you don't have to use GNOME. There are a ton of window managers that run on Linux, and you can find one that works better for you.

There's not much choice on Mac unless you install Linux on it.

Well even if you think the iPhone UX is great, they'll change it for no reason in the next release.
jlarocco··on Performance Improvements in .NET 11
Kinda. I use the `disassemble` function in Common Lisp quite a bit, and I can't work backwards to explain what a function is doing based on the disassembly.

BUT what I can do is see which functions are being inlined, which values are in memory versus in registers, see if things are being boxed and unboxed a lot, see if SIMD is being used, etc.

And more importantly I can compare two versions of a function to see which one looks better by those criteria. It's not perfect, but IME it works really well for guiding optimization.

I should add that I read the book "Assembly Language: step-by-step" by Jeff Duntemann, and wrote a Tic-Tac-Toe game in assembly ages ago, so that helps a bit to understand the syntax.

(And technically that's a patch file :-)

jlarocco··on A coffee shop owner used AI to make a menu poster. Then came the angry DMs
AI stealing their jobs isn't a "legitimate material harm"?

It doesn't matter anyway, because "using AI" doesn't make somebody a protected class. If people don't want to patronize businesses that use AI, there's nothing wrong with that.

jlarocco··on A coffee shop owner used AI to make a menu poster. Then came the angry DMs
Sorry, but the business owner has to own their actions. If they have a large customer base of artists who will feel betrayed by their using AI, then it was a mistake to use it.

It's her right to use AI, but the customers also have the right to say they won't patronize businesses who use AI, and are free to tell people they know that the business is using it.

If the shop's oat milk was really cow's milk, would it be "threatening their business" to tell other customers that?

jlarocco··on A coffee shop owner used AI to make a menu poster. Then came the angry DMs
Oh, I get it, but it only works if the "influencer" can actually influence a large enough group of customers, and my bet is that they can't.

If it were me, I would have called their bluff and ignored them.

jlarocco··on A coffee shop owner used AI to make a menu poster. Then came the angry DMs
Cancel culture or not, people are allowed to tell other people they know that something is happening, and those people can decide for themselves to patronize the business or not. To call it a threat is really exaggerating.

The headline makes it sound like people are phoning in bomb threats and violence, which doesn't seem to be happening at all.

Honestly, I think the business owner should have ignored these weak "threats" altogether. It doesn't have anything to do with coffee and it's unlikely they'll get any business because they use AI, so it can only hurt them.

jlarocco··on A coffee shop owner used AI to make a menu poster. Then came the angry DMs
Okay, but I (and I suspect a lot of people) really don't care if somebody is threatened in that way. If the business person doesn't want other people to know what they're doing then maybe they shouldn't do it. It's not worthy of a news article, IMO.

If somebody threatens them with violence (which is what "threat" is usually implying) then that's a different thing entirely.

Meh. The last Star Trek worth watching was TOS.
jlarocco··on US police fear Meta smart glasses could be used to secretly record them
Number one doesn't necessarily apply in the United States. A lot of our prisons (but not all) are privately run.

The rest of us fear that and nobody gives a sh*...

Good luck with that...

If they cared about the troops, they wouldn't send them on bullshit missions like whatever we're doing in Iran.

The intelligence is artificial, but the dollars it spends on your behalf are very real.
