Retiring TO something is important, but ideally it needs to involve a lot of in-person socializing, which many hobbies do not have. Golfing, for example, is pretty much the platonic ideal of a hobby that involves both socialization and old-person-friendly exercise.

Or maybe that's just the human condition? Retirement is a pretty recent concept anyway. Back when people were hunter/gatherers or subsistence farmers, you didn't have the option of retiring. You either kept working or you starved, perished from the elements, etc.

One other factor that others haven't yet covered is that the different lines had different capabilities, e.g. the T-89 had Computer Algebra System symbolic manipulation meaning it could pretty much solve many types of math problems on its own, so it wasn't generally allowed in school. And then the Ti-85/86 was a step down, but had matrix support that the lower models lacked, so it was necessary for some specific types of classes.

My favorite was always the TI-85/86 line. I loved those F1-F5 buttons right beneath the screen, which made the interface overall better to navigate. The first programming I ever did was on one of those (either the 85 or 82, can't exactly remember at this point which I owned first). And, the only thing of note I ever had stolen from me was a TI-82, taken out of my unattended backpack by another student during gym class :( (And I had even carved my name into the back of it with a knife, so it would've been identifiable.)

What are you envisioning exactly?

I'm not really sure what the point of this article is. Yes, obviously, you need to implement systems that are secure and performant so that you don't get a backed-up line of people waiting an hour just to get into the office in the morning. But that's a notably flawed rollout; millions of employees go into badge-in-required offices every day without issue. And it's kind of hard to imagine running a large office while lacking such basic physical security as "keep unauthorized people out of the building". Having electronic badges and readers is table stakes.

> especially when it comes to dynamic range

You can solve this by having multiple cameras for each vantage point, with different sensors and lenses that are optimized for different light levels. Tesla isn't doing this mind you, but with the use of multiple cameras, it should be easy enough to exceed the dynamic range of the human eye so long as you are auto-selecting whichever camera is getting you the correct exposure at any given point.

Beg for forgiveness, don't ask permission. I got Shingrix when I was under the age of 40, and at no cost to myself even, simply by scheduling a Shingrix vaccine at CVS. It wasn't until I went back for the booster shot months later that the nurse was like "Wait, aren't you too young for this?", but they nevertheless gave me the second dose to complete the vaccine course. You can just so things.

Your average HN reader can absolutely afford paying a few hundred bucks to avoid getting a potentially life-changing disease, and should. I know multiple young adults who got messed up by shingles.

The deorbits are controlled to occur over nonpopulated areas (i.e. the middle of the ocean). I don't think it amounts to much of a concern, compared to, say, the sum total emissions of all factories, power plants, ships, airplanes, and vehicles.

I'm amazed that the article doesn't discuss the end of ZIRP. The bursting of the art market bubble in mid 2022 coincides exactly with when interest rates started rising following the 'transitory' inflation caused by pandemic relief measures. This was also the same time that we started seeing hiring freezes in tech, the bursting of the luxury watch bubble, etc. It's all tied together, and has the same root cause: It stopped being cheap to borrow money, and it started being lucrative to lend it out for guaranteed returns (e.g. by buying Treasuries) rather than speculating on artworks, or NFTs, or whatever.

No, payroll is still down, it's just that labor is now being used less efficiently and thus less useful work gets done.

> So trigger some kind of process to cause the batteries to overheat

Where are you getting this part from? There's no evidence that the batteries were triggered to overheat; indeed doing so would be counter-productive, as it would cause the people holding the devices to know something is wrong and potentially move them farther away from their own body. The pagers exploded suddenly without warning. The only trigger/detonation involved was setting off the high explosive. The battery was uninvolved, only used to make the pager itself work.

It's war. Much worse things have been happening in this war already (e.g. Hezbollah explicitly targeting Israeli residential areas and killing civilians). By contrast this action seems much more targeted and justifiable.

If your bar for taking action is "there can't even be a chance of hurting a civilian", then your army can't do anything, and your entire civilian populace is slaughtered when it's taken over by the enemy intent on destroying your country.

You're forgetting that tens of thousands of Israelis from the north of Israel have been homeless and internally displaced since shortly after October 7th when Hezbollah started indiscriminately targeting Israeli residential neighborhoods in North Israel with rockets, artillery, and ATGMs, killing several civilians. This is not a tenable state of affairs, not militarily, nor politically. Israel is going to address it one way or another, one day or another, and perhaps they're starting now.

So in one sense you're right that it's to keep their population at bay -- because their population is absolutely fed up with the situation in North Israel and how people have been homeless for nearly a year now and a huge swath of the northern part of the country, will billions of dollars in real estate in total, is uninhabitable. And if this government can't provide security for its citizens, which is the most important thing a government can do by the way, then it will be replaced with one that can.

I think the simplest explanation here is that pagers are small and light and don't have that much free space inside them, and it's hard to fit enough explosive into them to reliably kill people. The figures I saw was only a few grams of explosive could be fit in them. If you look at the photos and videos that have been coming out today you'll see what the injuries look like; they're not as catastrophic as getting shot with a bullet, or anything close to a real explosive with orders of magnitude more explosive in it like an artillery shell, rocket, aerial bomb, etc.

I would guess Israel would have preferred more lethal pagers, but the required amount of explosive simply didn't fit. So the resulting deaths are from the people who got really unlucky, whereas getting wounded was the modal result.

You underestimate how many members Hezbollah has, and also, how unreliable these kinds of initial reports tend to be.

Yeah I mean it's basically just like mass-sending a spam text, no? All they need to know is the phone numbers of the pagers. Or even just the number range from which the pager numbers were assigned, and then spam the entire range. Spammers have simple enough software that can do all this; it doesn't seem like a sticking point for Mossad.

I mean they probably did hack to some degree the default software/hardware in the pager to get it to do something nonstandard. I doubt they have access to the full source code and build stack of the OG pager, so even just modifying the software running on it to do something different is indeed a hack.

It's a very minimal amount of pressure it can withstand, is the point. Certainly nowhere close to lethal explosive pressure. It's not a pressure vessel in the sense of the kind of pressure vessel it takes to make an effective bomb.

Batteries aren't pressure vessels though. Pressure vessels are generally decently large; how are you going to get one with significant capacity inside something as small and lightweight as a pager? Just putting in some plain explosives makes a lot more sense.
