Where I worked we had a very important time sensitive project. The server had to do a lot of calculations on a terrain dataset that covered the entire planet.

The server had a huge amount of RAM and each calculation block took about a week. It could not be saved until the end of the calculation and only that server had the RAM to do the work. So if it went down we could lose almost a weeks work.

Project was due in 6 months and calculation time was estimated to be about 5 1/2 months. So we couldn’t afford any interruptions.

We had bought a huge UPS meant for a whole server rack. For this one server. It could keep the server up for three days. That way even if wet lost power over the weekend it would keep going and we would have time to buy a generator.

One Friday afternoon the building losses power and I go check on the server room. Sure enough the big UPS with a sign saying only for project xyz has a bunch of other servers plugged into it.

I quickly unplug all but ours. I tell my boss and we go home at 5. Latter that day the power comes back on.

On Monday there are a ton of departments bitching that they came in an their servers were unplugged. Lots of people wanted me fired. My boss backed me and nothing happened but it was stressful.

Rustlers Rhapsody. A comedy western that mixes eras and has a genre savvy protagonist.

“We’ve got your friend!”

A 7/10 game would be better then no game. Besides sequels don’t erase the original.

To be fair they bought skype to break it’s end to end encryption at the behest of the us govt. In return they were awarded big contracts.

The war was VaulTec’s intended plan and they arranged for China to launch the first strike.

Ubisoft isn’t making money. That’s something wrong as far as the board is concerned.

Bit I’m usually better at it then the other person.

I hope your shoes are clean.

Yeah your drive to breathe is based on CO2 in the blood not O2 level. The higher the CO2 the more you feel the need to breathe. That’s why the capsule uses nitrogen. You don’t respond to the lack of O2 and can still flush the CO2 from your system.

Interestingly enough Luca Galante the creator spent 10 years coding digital slot machines. He used a lot of the techniques used by them to keep you playing. He just did it in a way to maximize fun instead of micro transactions.

As your stomach fills and stretches it sends a chemical “I’m full” message (GLP1) to the brain. When this signal is low you are hungary, medium you are full, and high you get nauseous.

Ozempic causes that message to be produced at low constant levels in addition to what is produced by the stomach.

So you don’t feel as hungry, you hit satiety faster, and if you continue to eat you get nauseous. This results in behaviors that reduce calorie consumption.

It also delays gastric emptying which also keeps you feeling full longer.

He also had a gun with the serial number removed. Also a felony.

Yeah she had character and was interesting. Crusher had hot redhead. I liked Crusher but would have preferred Pulaski stick around.

A perfect example of the magnificent bastard trope.

Pretty specific use case. A normal OS handleds time slicing and core assignment for processes and uses it’s judgement for that. So at any time your process can be suspended and you don’t know when you get your next time slice.

Same with when you make wait calls. You might say wait 100ms but it may be much longer before your process gets to run again.

In a real time OS if you have real time priority the OS will suspend anything else including it self to give you the time you request. It also won’t suspend you no matter how long you use the core.

So if you need to control a process with extreme precision like a chemical manufacturing process, medical device, or flying a rocket where being 10ms late means failure they are required.

However with great power comes great responsibility. You need to make sure your code calls sleep frequently enough that other tasks have time to run. Including things like file io or the gui.

Cool. I remember having to use Red Hawk Linux years ago. It’s a real time variant of Red Hat. It was such a pain to get the dependencies workin on it.

Farscape was once described as one Americans slow decent into the Australian S&M scene.

The solution for this is usually counter training. Granted my experience is on the opposite end training ai vision systems to id real objects.

So you train up your detector ai on hand tagged images. When it gets good you use it to train a generator ai until the generator is good at fooling the detector.

Then you train the detector on new tagged real data and the new ai generated data. Once it’s good at detection again you train the generator ai on the new detector.

Repeate several times and you usually get a solid detector and a good generator as a side effect.

The thing is you need new real human tagged data for each new generation. None of the companies want to generate new human tagged data sets as it’s expensive.

Yeah. The thing that made me “get” quaternions was thinking about clocks. The hands move around in a 2d plane. You can represent the tips position with just x,y. However the axis that they rotate around is the z axis.

To do a n dimensional rotation you need a n+1 dimensional axis. So to do a 3D rotation you need a 4D axis. This is bassicly a quat.

You can use trig to get there in parts but it requires you to be careful to keep your planes distinct. If your planes get parallel you get gimbal lock. This never happens when working with quats.
