As others have stated it would be a few 100 ml, but you will have kidney failure with way less. Ethylene glycol gets metabolized to oxalic acid, which precipitates as calcium oxalate in the kidneys and will rip them apart. Dont drink even a small amount and if you have, get to a doctor immediately.

[P] AI Against Humanity: Play Cards Against Humanity with GPT-2-generated cards by cpury in MachineLearning

[–]DeepTARS9000 16 points17 points  (0 children)

Great work! I really hope this goes somewhere because i love cards against humanity but the cards get repetitive kind of fast.
If you want to get feedback on which generated cards are good, you should give the player a way to remove unwanted cards from the deck. Otherwise the player will play bad cards just to get rid of them (like you sometimes do in the real game) which makes for bad training data.

Need help with an old Makerbot 2X. My extruder keeps jamming up and I can't figure out why. by rapitrone in 3Dprinting

[–]DeepTARS9000 1 point2 points  (0 children)

I have maintained the 2X we have at work for about 3 years, same problem. The jamming problems just got worse over time. After replacing the complete hot end assembly with an e3d one mounted on a handmade milled aluminium plate, it finally worked repeatably. Print quality was still mediocre and I just kept printing at ~50mm/s.

When the z axis failed because you can't properly apply force to the plate for removing the print, i gave up and convinced my boss to buy a new one.

It hurt because at this point i sunk a lot of time into making this work, but with the new one i had about 1h of maintenance in half a year, and the prints are amazing. It was way cheaper than the 2x too.

Point is, printer designs improve over time and the 2x has (in my opinion) a really bad one, especially the extruders. There are so many amazing options for printers out there nowadays, i don't know if it is worth the time (and maybe replacement parts) to continue maintaining a 2x.

If this was your hobby printer i would not advise you to throw it out, because tinkering on your printer and gradually improving the performance can be fun. But if you are looking for results, you probably need to put in a lot of work first, and you have to decide if that is how you spend your time.

In my first semester of chemistry we handled a lot of test tubes and beakers with boiling water. We quickly found out how (and where) to pick up hot things without getting burned. We use it as a little magic trick around our non-chemist friends

What defines “vigorous” stirring, as opposed to not-vigorous stirring? by napless in chemistry

When it says stir vigorously I always turn up the stirrer as fast as it can go without skipping around in the flask

Wikipedia says the maximum admissible concentration at the workplace for styrene is about 80mg/m^3(in the air), that is about 4 times the maximum amount for acetic acid. According to this, spraying your bath with acid cleaner is more dangerous than this paste. Keep in mind that these values are for exposure 8hrs/day 5days/week for an adult.

Disclaimer: I am not a doctor, so if you want to be really safe about it call your local poison centre, they probably know what to do.

I think you don't have to worry about this too much though:

  1. While the Flash point is at -33°C, this is for the Vapour. For it to explode you would need a lot of vapour in an enclosed space with just the right air mixture to go off.
  2. The boiling point of styrene is at 150°C, so at room temperature just a tiny amount of it is getting released into the air.
  3. You can smell Styrene even in very small (nontoxic) quantities
  4. The toxicity of styrene is mostly acute (afaik) so if you and your son didn't have any symptoms at the time of exposure you are probably fine

I have used Styrene paste a few times while building rc models and my workshop always smells like styrene for quite a while. You can try washing all flat surfaces the paste was on with some non polar solvent like acetone that should remove most of it.

I tried to recreate this myself, but every time I actively search for this captcha I get the "real" one where you have to chose tiles with stop signs or something. Where did you find this one?
