  • Software is a tool. I develop stuff that i know is of interest to companies working with everything from nuclear energy to hydrogen electrolysis and CO2 storage. I honestly believe I can make a positive contribution to the world by releasing that software under a permissive licence such that companies can freely integrate it into their proprietary production code.

    I’m also very aware that the exact same software is of interest to the petroleum industry and weapons manufacturers, and that I enable them by releasing it under a permissive licence.

    The way I see it, withholding a tool that can help do a lot of good because it can also be used for bad things just doesn’t make much sense. If everybody thinks that way, how can we have positive progress? I don’t think I can think of any more or less fundamental technology that can’t be used for both. The same chemical process that has saved millions from starvation by introducing synthetic fertiliser has taken millions of lives by creating more and better explosives. If you ask those that were bombed, they would probably say they wish it was never invented, while if you ask those that were saved from the brink of starvation they likely praise the heavens for the technology. Today, that same chemical process is a promising candidate for developing zero-emission shipping.

    I guess my point is this: For any sufficiently fundamental technology, it is impossible to foresee the uses it may have in the future. Withholding it because it may cause bad stuff is just holding technological development back, lively preventing just as much good as bad. I choose to focus on the positive impact my work can have.


  • Oh, I definitely get that the major appeal of excel is a close to non-existent barrier to entry. I mean, an elementary school kid can learn the basics(1) of using excel within a day. And yes, there are definitely programs out there that have excel as their only interface :/ I was really referring to the case where you have the option to do something “from scratch”, i.e. not relying on previously developed programs in the excel sheet.

    (1) I’m aware that you can do complex stuff in excel, the point is that the barrier to entry is ridiculously low, which is a compliment.



  • You are neglecting the cost-benefit of temporarily jumping to the wrong conclusion while waiting for more conclusive evidence though. Not doing anything because evidence that this is bad is too thin, and being wrong, can have severe long-term consequences. Restricting tiktok and later finding out that it has no detrimental effects has essentially zero negative consequences. We have a word for this principle in my native language - that if you are in doubt about whether something can have severe negative consequences, you are cautious about it until you can conclude with relative certainty that it is safe, rather than the other way around, which would be what you are suggesting: Treating something as safe until you have conclusive evidence that it is not, at which point a lot of damage may already be done.








  • Yup, who would have though that Russia invading their neighbour suddenly caused the entirety of western Europe to start the largest investments in military and weapons manufacturing since the cold war?

    Looking at the results of this war so far (major expansion of NATO in the North, massively increased military spending in all of NATO, massively increased size of the Ukrainian military), you would almost think Putins goal was something completely different than preventing NATO expansion and “de-militarizing” Ukraine.

    It’s almost like the best way of preventing your neighbours from building huge militaries and joining alliances is by cooperating with them and helping them feel safe, rather than threatening, coercing and bombing them.


  • It’s sad, but countries like Russia show us very clearly why nations that want peace need to prepare for war.

    I would love to not need to spend a cent on our military, or weapons manufacturing, but the hard reality is very clearly that if we aren’t capable of mass producing weapons, we’ll likely be invaded and killed.

    That’s a major part of the issue Europe is facing now: We’ve scaled down weapons production since the 90’s, and now that we suddenly need millions of artillery shells it takes time to rebuild production capacity.

    Hopefully Russia gets the picture soon, that we’ll keep scaling up until every Russian invader is gone, and we can go back to not spending money on war…


  • Wow, I Wonder why everyone that’s left in the regime that deports and persecutes dissenters says they are in support of that regime?

    Ukraine never invaded anybody. Giving them weapons so they can throw out the people invading them, taking their land and molesting their people is a good thing. Russia has clearly shown that the only way to get rid of the plague that is Russian soldiers on foreign soil is to kill them. That’s why we have this war that Russia has chosen to engage in, and which Russia can choose to withdraw from at any time. That’s why Russians are dying by the hundreds of thousands.


  • Where I live they were systematically nice people that helped keep everybody safe. If they found some drunk/high person that needed help, they would drive them home. When we were teens and had beach parties, a couple of them would typically hang around somewhere out of the way, and only intervene if someone was being an asshole trying to start a fight (and they would tell people to pick up their glass bottles so kids wouldn’t get hurt the next day). If we were otherwise hanging around they might chat to us and ask what was going on around the neighbourhood, and nobody had an issue telling them anything, because we knew they were just there to look after and help people.

    Obviously, I can tell that my experience with police growing up is far from what can be expected a lot of other places. I really do wish more places had police like we did.


  • Hehe, exactly :) the thing with gases is that the line between completely fine (campfire outside) to potentially lethal (liquid nitrogen evaporating in a small, poorly ventilated garage) can be harder to see and judge for an amateur than a lot of other things. Anyone would understand that they should avoid getting acids or toxic chemicals on their skin, and the protective measures are quite simple to carry out. The same is true for most flammable or explosive liquids or solids. So the idea behind my advice was really “If there’s something that’s likely to hurt you because you aren’t properly aware of the danger involved and how to mitigate it, it’s likely to be a gas, so be extra, extra careful around gases, gas producing reactions, and volatile compounds.”


  • If you have a fume hood that’s good of course, but since the question was about advising amateurs on safety, my advice is restrictive, because gases can be very dangerous in subtle ways.

    As an amateur: Do you know how to properly work in a fume hood so that it protects you? Do you know its capacity, and what to do if something unexpected leads to gas development over that capacity? Have you had training in using this stuff, so that you can react properly and quickly if something goes wrong, rather than freezing up?

    In short: Because the potential dangers when working with a lot of gases are harder to detect, and harder to mitigate, than when working with other stuff, I’m taking a restrictive approach in my advice.

    For you question on pyrophoric gases: They can remain in contact with air for a while (several minutes, depending on concentration) before igniting. Worst case, the room around you can fill with gas from a leak before causing a gas explosion. In principle you can also inhale gas from this leak, such the the explosion also takes place inside you :)


  • Anther chemist stepping in here: Anything that produces an off-gas of any kind that does anything other than smell bad should be considered potentially lethal. People have died from working with liquid nitrogen or dry ice without proper ventilation. In addition, a gas explosion can be far worse than any other explosion you are likely to pull off by accident, and if you have a leak somewhere you may have no clue how much explosive gas is in the room with you. Some gases will react and form acid when it gets into your airways, essentially acting as an invisible acid that can jump from the table into your face.

    In short: Stay away from dangerous gases and stuff that makes them, and consider pretty much all gases as dangerous unless you know for a fact that they aren’t. Other than that, the potential dangers of backyard chemistry can largely be mitigated by using common sense and working with small amounts of chemicals, good luck :)


  • Bra! Dette er første solide steg i kraftig styrking av forsvarsevnen og å skape et troverdig forsvar. Det er fort gjort å glemme at med dagens forsvar er det bare å glemme å mobilisere 100 000 mann selv om vi hadde hatt utstyret til det: Vi trenger en kraftig økning av både folk med fersk trening og stående styrker med kompetanse og kapasitet til å ta imot og trene mobiliserte styrker ved behov.

    Neste steg er innkjøp av utstyr som gir kapasitet til å utruste et mobiliserisngsforsvar på 100-200 tusen pers. Vi ser soleklart fra Ukraina hvor fort ting kan gå til H hvis vi ikke klarer å stille et troverdig forsvar ila. 1-2 uker etter dritten treffer vifta. Finland får det til, da kan vi også få det til.
