You would think the therac-25 was enough of an engineering lesson on designing safety-critical systems in software that lack hardware redundancy. Maybe they didn't consider the door handles "safety critical".
Another lesson not learnt from therac-25 (and really most disasters caused by humans) is that safety is a cultural issue, that needs to be taken seriously from top to bottom in the organization.
I don't know about hardware redundancy, but yes for at least "easily verifiable limiters".
What is "hardware" anyway? Does a microcontroller-based integrator or debouncer count? Depending on how you define that, it can become a serious roadblocker. But anyway, I guess that point is moot for a door handle, you can fix it with stuff that is unambiguously hardware.
Was just about to link this. I was a part of this scene at age thirteen! Was largely how I taught myself fundamentals of programming and how to solve problems. When I'm feeling particularly nostalgic, I'm occasionally tempted to fire up something like DJGPP and finish my childhood dream of making a useful GUI for MS-DOS.
As surveillance of social media ramps up, either by the government or by angry mobs, they're rapidly growing to be essential to use any unencrypted platform.
I believe it says quite a lot when a major and supposedly reputable institution like the WSJ will sacrifice journalistic rigor when they see an opportunity to potentially besmirch the image of a sharply unpopular demographic. Facts still matter over agenda. People should be fired for this.
If inflation is lower than the rate the federal reserve hikes rates to, you can ride out stagflation in money market funds and other types of income-generating investments. The real pain is when it doesn't. Stocks decline, cash declines, and there really is nowhere to hide. TIPS? I-bonds? Both are indexed to the CPI, which policymakers have loudly signaled they are okay gaming and manipulating for political favour.
You’re vastly underestimating the income and political effects of stagflation. Historically speaking, one doesn’t ride it out. It’s fixed fast or the system collapses.
I'm sure it isn't luck but at the same time I watch these things and genuinely don't understand how they do it. Particularly the whole thing of seeing and reacting that quick.
It reminds me of how bad I am with rhythm games. I can't even get through Easy on DDR because the arrows move too fast. It's like I can't read them and react quick enough.
Typically I do much better with games where the point isn't to see, process, and react within milliseconds. I definitely think there is a type of brain that can play games like these and another type that can't, and I'm in the latter.
> I can't even get through Easy on DDR because the arrows move too fast
The trick to basically all of these games is not to actually try and look at the arrows. There are a lot of them, they are moving fast, your conscious mind can't actually track and respond to each one of them individually.
But with practice you can train your self to more-or-less automatically respond to the sequence - there are only a handful of variations, and you learn the patterns that they typically arrive in.
(For a little while I had too much free time on my hands, and was in the top-100 BeatSaber players)
I think you can train it, at least that's what I did with Stepmania in the early 2000s. I was watching in awe how people could manage to get perfect scores when I could hardly see the steps before they were at the bottom of the screen.
Eventually I learned to stop looking at the individual entities, and just "stare in the middle" kind of, and you stop "looking" and start sensing in a way, without looking directly at them. They might just flash by, but it's enough for your brain to be able to at least figure out what right finger to use.
Then it's just a bunch of training :) I think it's fairly established that "reaction time" is something you can train, you just need to always be at the limit and slowly make it faster and faster. Same with speed-reading/listening I think.
How much effort do you put into trying before you quit?
I used to look at games like Hades and Returnal and see nothing but chaos. But with enough time on the sticks both games became instinctual and I was able to find a flow.
Yes, there's variation in potential range but most brands are capable of most things if you give them enough time to grow the necessary neurons and pathways.
I just timed DDR First Mix on the default settings on Boom Boom Dollar (135bpm). You have 2.67 seconds from the arrow first appearing to needing to input a step. 2,667 milliseconds. Reaction time is not your issue. DDR’s arrows actually move extremely slowly.
To have something that is genuinely private and would qualify for listing in the app store, options are pretty limited. I don't think they allow developers to use onion services or anything like that. You could host the server in other countries, but even in hostile countries, it's not a leap of logic to assume the NSA would have an easy time getting in there all without the worry of that pesky "legal" thing.
Closest example I could think of would be Hans Reiser/Reiserfs. It's a more sordid story than just getting hit by a bus, though. Ultimately the project just died.
I don't think this is a good example though as the "sordid" part also made the project toxic for anything that might have otherwise chosen to take it on.
