Similar with Y2K — it was only a nothingburger because it was taken seriously, and funded well. But the narrative is sometimes, “yeah lol it was a dud.”

All this hysteria over nuclear weapons is overblown. We’ve known how to build them for 75 years yet there hasn’t been a single one detonated on inhabited American soil. They’re harmless

The question is, what will happen in 2038 when y2k happens again due to an integer overflow? People are already sounding the alarm but who knows if people will fix all of the systems before it hits.
zik@lemmy.world 8 months ago
It’s already been addressed in Linux - not sure about other OSes. They doubled the size of time data so now you can keep using it until after the heat death of the universe.

I can’t remember the name but I think this is some kind of paradox.
Like the preventative measures we’re so effective that they created a perception that there was no risk in the first place.
Matombo@feddit.de 8 months ago
It’s called the prevention paradox: It’s when an issue is so severe that it is prevented with proactive action, so no real consequenses are felt so people think it wasn’t severe in the first place.

I wasn’t working in the IT field back then, as I was only 16, but as I knew that it’d most likely be my field one day (yup, I was right), I followed this closely and applied patches accordingly.
Everything kept working fine except this one modem I had.
FunkFactory@lemmy.world 8 months ago
I kinda wish I knew what it was like working on Y2K stuff. It sounds like the most mundane bug to fix, but the problem is that it was everywhere. Which I imagine made it pretty expensive 👀
AA5B@lemmy.world 8 months ago
Most of the y2k problem was custom software, and really old embedded stuff. In my case, all our systems were fine at the OS, and I don’t remember any commercial software we had trouble with, but we had a lot of custom software it’s problems, as did our partners
Dasnap@lemmy.world 8 months ago
And that modem was handling the nuke codes, right?
Tranus@programming.dev 8 months ago
Y2K specifically makes no sense though. Any reasonable way of storing a year would use a binary integer of some length (especially when you want to use as little memory as possible). The same goes for manipulations; they are faster, more memory efficient, and easier to implement in binary. With an 8-bit signed integer counting from 1900, the concerning overflows would occur in 2028, not 2000. A base 10 representation would require at least 8 bits to store a two digit number anyway. There is no advantage to a base 10 representation, and there never has been. For Y2K to have been anything more significant than a text formatting issue, a whole lot of programmers would have had to go out of their way to be really, really bad at their jobs. Also, usage of dates beyond 2000 would have increased gradually for decades leading up to it, so the idea it would be any sort of sudden catastrophe is absurd.
TheOctonaut@mander.xyz 8 months ago
The issue wasn’t using the dates. The issue was the computer believing it was now on those dates.
I’m going to assume you aren’t old enough to remember, but the “only two digits to represent the year” issue predates computers. Lots of paper forms just gave two digits. And a lot of early computer work was just digitising paper forms.
GoodEye8@lemm.ee 8 months ago
You’re thinking of the problem with modern solutions in mind. Y2K originates from punch cards where everything was stored in characters. To save space only the last 2 digits of the year because back then you didn’t need to store the 19 of year 19xx. The technique of storing data stayed the same for a long time despite technology advancing beyond punch cards. The assumption that it’s always 19xx caused the Y2K bug because once it overflows to 00 the system doesn’t know if it’s 1900 or 2000.
frezik@midwest.social 8 months ago
With an 8-bit signed integer counting from 1900…
Some of the computers in question predate standardizing on 8 bits to the byte. You’ve got a whole post here of bad assumptions about how things worked.
SkippingRelax@lemmy.world 8 months ago

You don’t spend much time around them, do you?
breakingcups@lemmy.world 8 months ago
You do realize that “counting from 1900” meant storing only the last two digits and just hardcoding the programs to print"19" in front of it in those days? At best, an overflow would lead to 19100, 1910 or 1900, depending on the print routines.
Matombo@feddit.de 8 months ago
Oh boy you heavily underestimate the amount and level of bad decision in legacy protokoll. Read up in the toppic. the Date was for a loong time stored as 6 decimal numbers.
thomasw@sh.itjust.works 8 months ago
And then there is PIC 99 in Cobol. In modern languages, it makes no sense, but there is still a lot of really old code around and not everything is twos complement, especially if you do not need the efficiency in memory and calculations.

I literally had this exact exchange with someone last year, when they tried to cast doubt on global warming by comparing it to the ozone. Another person did the same , using acid rain, and I pointed out that the northeast sued the shit out of the Midwest until they cut that shit with the coal fire power plants.
Yaztromo@lemmy.world 8 months ago
The Conservative Party led Canadian Government and the Regan-era Republican US Government started working on the US-Canada Air Quality Agreement, which was signed by the George H.W. Bush administration into law in the US (and the Brian Mulroney led Government of Canada).
That’s right — two Conservative governments identified a problem, listened to their scientists, and enacted a solution to acid rain. And now the problem has virtually disappeared.
Oh how low Conservatives have fallen on both sides of the border since those days.

I use talking points like these a fair amount with Republicans. Try to get them to think back to when they were leaders in environmental policy. Get back to their roots of environmental stewardship. It seems to have moved the needle slightly.

Except we were kicking the can with sun screen regulation until 2022.

Until this law, sun screen lotion didn’t have to prove that they actually provided the SPF that they claimed.
MisterFrog@lemmy.world 8 months ago
I’d argue that while we are much more diligent than other countries, and regulations are much stronger. The average person doesn’t pay nearly enough attention, and the fact the UV index isn’t required to be mentioned on weather reports, or as prominently or more prominently than the temperature, is a big oversight in my opinion.
I check the UV every time I go outside (other than when it’s died down over winter), just as you’d check the temperature, and I think it’s wild barely anyone else does.
MisterFrog@lemmy.world 8 months ago
The sun is still awful here, the ozone hole is still a thing.
But thanks world, at least I can go out for a solid 4.5 months of the year without worrying about the sun at all, and 6 of only needing to be somewhat careful. Not too shabby :)

This is entirely on China and China alone. No one is forcing their factories to cut corners and use them.

Imagine if we did this with climate change. Imagine if we tried to switch to renewable energy en masse 20 years ago.
Johanno@feddit.de 8 months ago
Problem with that is that in comparison the alternative to FCKW was not that more expensive and then a cheaper one was invented shortly after.
For climate change you basically can double our energy costs and therefore double the cost of almost everything.
Jax@sh.itjust.works 8 months ago
Not to seem callous, but the first world could learn to live off of a little less.

This has since been determined to have tack on benefits in the fight against the climate crisis as well, it’s halved the potential growth in global average temperatures by 2100, which cannot be overstated in just how fantastic that is.
We went from everyone being baked alive and having 20 kinds of skin cancer to boot to merely dealing with catastrophic climate change and society changing people migrations the likes of which haven’t been documented since the successive eras of steppe invasions into Europe, China, India, and the Middle East.

@MattWalshBlogRemember when they spent years telling us to panic over the hole in the ozone layer and then suddenly just stopped talking about it and nobody ever mentioned the ozone layer

@DKThompWhat happened is scientists discovered chlorofluorocarbons were bad for the ozone, countries believed them, the Montreal Protocol was signed, and CFC use fell by 99.7%,leading to the stabilization of the ozone layer, perhaps the greatest example of global cooperation in history.

EddoWagt@feddit.nl 8 months ago
As far as im aware the hole in the ozone layer is basically gone
Lyrl@lemm.ee 8 months ago
The ozone hole size is influenced by the strength of the polar vortex, the Antarctic temperature, and other things in addition to the concentration of CFC molecules. It’s barely shrunk, but CFCs are so long-lived that was expected - the critical point is it stopped growing over 20 years ago. I believe they expect to start seeing shrinking within the next decade.
AA5B@lemmy.world 8 months ago
Looks like it had been expected to heal by 2040, but might also be affected by by climate change
Ugurcan@lemmy.world 8 months ago
TBH “The whole world agreed on something” narrative doesn’t really reflect what happened.
Actually, The Industry dropped using CFC after a cheaper and luckily safer alternative has been discovered right around that time.
MystikIncarnate@lemmy.ca 8 months ago
The fact is, most companies are fine to let an existing system run rather than replace it with one that has a cheaper consumable thing, provided they can still get that consumable and the cost of replacing that system is high.
Basically, corps would have kept buying and using CFCs because replacing the refrigeration system is too costly.
Not only was an alternative found that was cheaper and safer and almost as good (as effective), but scientists and engineers put in the effort to find ways to adapt existing systems to the new working fluid. All for significantly less than replacing the system.
Not only was a replacement found, but it was made economically viable for widespread deployment in a very short timeframe; not having a short development time, but also a very short duration to deploy the new solution to an existing system.
You’re right, that it was cheaper and everything, but most of the time changing the working fluid of a refrigerator/air conditioning unit, will require that the system is replaced. They worked around that. Additionally, you’re correct that it was industry that made the change and pushed it to their clients.
I just want to make sure we recognise the efforts put in by the scientists and engineers that enabled the rapid switch to non-CFC based cooling systems. It’s still an amazing achievement IMO, and something that required a remarkable amount of cooperation by people who probably don’t cooperate often or at all (and are, in all likelihood, fairly hostile to eachother, most of the time).
IMO, that’s still one of the best examples of global cooperation that anyone could possibly point to. Rarely do we have a problem where there’s almost universal consensus on the issue and how to fix it. In this case, there was. That level of cooperation among the people of earth is borderline unparalleled; the only other times we cooperated this well that people would know about are usually negotiations done with the barrel of a gun. Namely the world wars. One group said that we’re going to do a thing, another group said nope. It was settled with lives, bullets and bombs, and nearly every person alive was on one side or the other… Except Sweden, I suppose… And maybe smaller countries that didn’t have enough of an army to participate. (I’m sure there’s dozens of reasons, but I’m not a historian)
Without guns, bombs, or even threats, just a presentation of the facts and a proposal for a solution, everyone just … went along with it.
To me, that’s unprecedented.
marcos@lemmy.world 8 months ago
There was a necessary round of nearly all governments on Earth agreeing to fine and extinguish business or even throwing executives on jail if they insisted on using the more expensive alternative.
Only after that people stopped using CFCs.

Turns out, that the hole in the ozone layer didn’t get repaired. In fact, it’s larger than it’s ever been and above the Antarctic. Antarctica is currently experiencing a mass die-off of animals.
TheDemonBuer@lemmy.world 8 months ago
I’ve always hated this comparison because the two problems are just not the same, at all. CFCs were nowhere near as ubiquitous as fossil hydrocarbons, and CFCs had an essentially drop-in replacement, which fossil fuels do not. There’s no non-hydrocarbon fuel that we can just replace for coal, natural gas, gasoline, diesel fuel, jet fuel, etc. None that I’m aware of, anyway.
