    They wore masks, had negative pressure ventilation suits on

    I hope those were positive pressure suits, positive pressure helps to keep dust out of the suit. Negative pressure ventilation is used to help sick people breathe easier, like the iron lung for example.



  • Once you finish it, it’s actually really fun watching other people’s playthroughs as well - getting to relive some of the moments vicariously through other people’s eyes is almost as much fun as experiencing them yourself the first time.

    It’s also quite amazing just how different each playthrough can be, since the game is so non-linear, people take some crazy paths to get to the end ! It can be frustrating as well when someone just can’t see what is in front of their face though :)

    There are also so many subtle elements scattered around that most people miss on their first playthrough, and watching someone else play it really made me appreciate many of the details I missed on my own playthrough and even make connections I didn’t before, and understand aspects of the story that I didn’t fully get the first time.




  • You have to realize that popular culture was very tightly controlled and restricted by the Polish communist government at this time. This photo was taken at the Jarocin festival, which was a rare chance to see many bands play that otherwise had no radio play or record contracts and often played styles of music that were viewed with great suspicion by the establishment. Recording these live performances and trading tapes was often the only way people got to hear many of these bands.

    I grew up in a neighboring country during this time, but I wasn’t much into the rock scene then - I was into folk music, which had a similar scene in my country - many folk artists were straight up banned by the government, so it was impossible to hear them on the radio or buy their records, but tape recordings of live performances existed and were traded among the fans. Same of my favorite music from this period only existed in this form. There were even recordings of shows that got shut down by the police mid-set.

    The 80s were a period of economic stagnation in eastern Europe, resulting in a lot of pent up anger and angst in the youth, and at the same time, the establishment was slowly losing its grip on the population. As a result artists were getting increasingly bold in channeling this anger and dissatisfaction, of pushing the boundaries of what was allowed, sometimes crossing them and getting slapped down - but you never knew what could happen at a large gathering of the youth back then - taping was an important tool to document and spread this to the wider population.


  • Most Polish people would disagree. Poland got pretty fucked in ww2, from all sides, but at least they managed to hold on to some of their sovereignty and not be forced to join USSR as a Soviet Republic.

    This partially allowed the democratization movement to form in Poland in the 80s (with Solidarność) and eventually for Poland to get out from under Russia’s boot and join the EU and NATO, and avoid the fate of former Soviet Republics like Belarus and Ukraine.




  • The only fuel you can make from water is hydrogen. The RS-25 engines used on the SLS core stage and the Space Shuttle used liquid hydrogen, as did the J-2 engines on the second and third stage of the Saturn V (but not the first stage, which used RP-1 (kerosene) burning F-1 engine)

    Starship’s Raptor engines use liquid methane however. There are a bunch of tradeoffs between the different fuels, but generally liquid hydrogen is more difficult and expensive to deal with. With low cost reusability being one of the primary objectives of Starship, liquid methane was chosen as the best option. The fact that it can also be manufactured on Mars was also considered, since CO2 is abundant in Martian atmosphere.








  • What is your source for this ? Recent polls show reunification support is still <2%, with about 6% open to reunification eventually but not now.

    In 2018, before the crackdown in HK, the reunification support was 3%, with 13% open to it eventually - the events in HK have definitely significantly eroded support for reunification in Taiwan.

    I have family in Taiwan and literally don’t know a single Taiwanese person that wants reunification with the PRC.
