Notably, DOOM crashed before Windows CE.
Seriously… I’m most impressed that this PDA kept an application running for 2.5 years. I’d be shocked if any modern hardware could do this, even while disconnected from the Internet.

You have 13 years to upgrade to 64-bit ints or switch to a long long for time_t. Lots of embedded stuff or unsupported closed-source stuff is going to need special attention or to be replaced. I know the OpenFirmware in my old SunServer 600MP had the issue. Unfortunately I don’t have to worry about that.
Most 32-bit games won't be updated, we'll have to resort to faking the time to play many of them.
Most 32-bit games written for some form of Unix will use the system time_t if they care about time. The ones written properly, anyway. Modern Unix systems have a 64-bit time_t, even on 32-bit hardware and OS. If it’s on some other OS and uses the Unix epoch on a signed 32-bit integer that’s another design flaw.

#1932038 is going to be a fun year.

You’ve got 13 years to update unless any of your code includes dates in the future. Just stay away from anything related to mortgages, insurance policies, eight year PhD programs, retirement accounts…

Try a Breville PolyScience... https://www.breville.com/en-us/product/csv750 Or if you want something even beefier: https://sammic.com/en/smartvide-xl
It looks like the Breville is the most affordable at $600. Currently I'm paying optimistically $45/90 days or $0.50/day. For the Breville to match that it would need to survive for 3.29 years. Will it?
Maybe... the Sammic is made for a high volume commercial kitchen

The Porsche quote reflects a wider design philosophy that says "Ideally, all components of a system lasts as long as the design life of the entire system and there should be no component that lives significantly longer. If there is such a component, it has been overengineered and thus the system will be more expensive to the end consumer than it needs to be.". It kinda skips over maintenance, but overall most people…
Anyone can build a bridge, but it takes an engineer to barely build a bridge.
This is a great quote for the topic, but the quote is normally about a bridge that barely stands.
I'm chuckling at the thought of barely building something. (All in good fun, thank you.)

There was an aluminum extrusion company that falsified test records for years. They got away with it because what's a few % when your customer's safety factor is 2. Once they got into weight sensitive aerospace applications, where sometimes the factor is 1.2, rockets starting blowing up on the launch pad. https://www.justice.gov/archives/opa/pr/aluminum-extrusion-m...
Should have resulted in jail time. A monetary fine is no deterrent.
It did result in jail time. The linked document states that the testing lab supervisor was sentenced to 3 years. (Not sure how much of that time was actually served, apparently he was suffering from dementia.) More info: https://www.oregonlive.com/portland/2018/08/company_supervis...
Also a correction to GP: They were payload deployment failures, they didn't blow up on the pad. More here: https://arstechnica.com/science/2019/05/nasa-finally-conclud...

#197Not a comment on the post, but I sure wish Jira would load even half as quickly as this site.
Perhaps it's hosted on a disposable vape?
Pretty sure the dead sibling to this comment shouldn't be dead.

I'd be more impressed by current software not crashing for 2.5 years than hardware, but that might be I'm a software developer, not a hardware developer :-)

#199About a year ago I was looking at Crash Bandicoot timer systems and I found that Crash 3 has a constantly incrementing int32. It only resets if you die. Left for 2.26 years, it will overflow. When it does finally overflow, we get "minus" time and the game breaks in funny ways. I did a video about it: https://youtu.be/f7ZzoyVLu58
Is it common to default to a signed integer for tracking a timer? I realize being unsigned it would still overflow but at least you'd get twice the time, no?
Some C programmers take the view that unsigneds have too many disadvantages: undefined behaviour for overflows, and weird type promotion rules. So, they try and avoid uints.

> Back in the real world, no race team would agree that their cars should disintegrate after one race. Wasn't F1 teams basically doing this by replacing their engines and transmissions until the rules introduced penalties for component swaps in 2014?
If you go back further than that, teams used to destroy entire engines for a single qualifying. The BMW turbocharged M12/M13 that was used in the mid-eighties put out about 1,400 horsepower at 60 PSI of boost pressure, but it may have been even more than that because there was no dyno at the time capable of testing it. They would literally weld the wastegate shut for qualifying, and it would last for about 2-3 laps:…
Current examples would be drag racing cars that have motors that are designed and used in a way that they only survive for about 800 total revolutions.
