  • The safety angle may be overplayed but it is not the only element of this kind of change. Better and safer infrastructure for walking and cycling encourages walking and cycling.

    So there are a whole host of benefits: reduced pollution, better citizen health and wellbeing, encouraging use of local walkable businesses, etc.

    Also a reduction in deaths and injuries on a background of increased pedestrian and cycling is also noteworthy. I.e. not just reduced the existing injuries but also less injuries despite more people.at risk.



  • Yeah I was surprised they took it down. I think it’s a foolish knee jerk reaction and is patronising towards readers.

    Ironically there is know nothing to put the current spike of interest in context as you can’t read the letter on the guardian website.

    I’m actually really unimpressed with the guardians action - they don’t respect their readers and clearly no longer believe in freedom of speech. They could have modified the article to put the letter in context themselves rather than link to a 20 year old article criticising it. It also makes it hard for those who want to push back against the letter and answer those who are pushing it.


  • If you implement it from fresh then it is a new program. What matters is what your contract says about what you produce - some contracts pay claim to anything you make even outside of working hours.

    Also if you rewrite it, while technically it is a fresh project if there are substantial similarities in how you implement it there could be an argument made that you have reused code that belongs to the company. Even if that is technical false it could be something you’d have to defend sometime in the future. As others have said, implementing the program in a different language and using a different methodology wherever possible should help protect against that.

    I think the advice others have given that you should review your contract with a lawyer is sound even if this will be FOSS. It’s mainly about ensuring you don’t inadvertently open yourself to potential legal repercussions down the line, even if your employers at the moment seem benign. If you do work for a company that lays claim to everything you produce even in your off hours then I would strongly recommend you consider leaving or an exit plan, particularly if you are the sort of person who would be working on your own projects for fun or even your own business ventures.




  • So big mistake here: NAC is not harmless. It does have side effects and it also has toxicity at high doses.

    It has not been studied in long term use orally or IV, it’s main use bomg short term use for paracetamol overdose treatment. Inhalation is more studied but it is not absorbed into the body in the same way.

    We think it is safe but we haven’t actually done human trials to be sure. What we have found in mice is that high doses can cause lung and heart damage and also when it comes to alcohol it is protective if taken before alcohol consumption BUT it amplifies the toxicity to the liver if about 4 hours taken after alcohol. All of this is summarised on the Wikipedia page which looks to be good quality.

    Overall it may be a useful drug but don’t take it off label or self medicating. Medicine is littered with unexpected effects of drugs that only came out once it was too late. Thalidomide is a good example - a “wonder drug” for nausea used in pregnancy that was not tested and caused horrific birth defects which only became evident when it was too late.

    Your body is not a lab, be careful experimenting with supposedly “safe” drugs.


  • This is incorrect, I’ve just tested it myself. You have one private Icognito session in Firefox at a time, and all new windows are in that session. The Icognito session resets once all the private windows are closed.

    I logged in to Kbin in one private window, then opened a new private window from my main firefox window and when i navigated to Kbin I was logged in. I closed all the private windows and then opened a new private window and I was no longer logged in.

    This is the same in Chrome, I did the same test and had the same results.

    Tl;dr: Incognito windows and tabs are not separate sessions. You must close all Icognito sessions to get a new cleared session.


  • I think your second half is bang on the nail for the missing part of this story. It is not just to drive search directly, it is also to control the browser market long term.

    That’s what Microsoft did very successfully with Internet Explorer too. They have it away for free and bundled it with Windows, killing all competition and then used that to leverage MSN. They also didn’t follow standards and through market dominance shaped the internet.

    Google sort of follows standards but they have also forced through proprietary standards or have broken code which is why some websites don’t work well in Firefox or Safari even now.

    Chromium may be open source but it is a tool used by Google to control and dominate the internet.

    Apple is exactly the same with WebKit - they talk about privacy and security but the real motivation is surpressong alternate routes to the internet from their devices whic then keeps iron control over payment methods particularly in iOS. Yet people in the apple eco system buy into the narrative that the one piece of software you’re not allowed in iOS is a non apple web browser, as if that is an acceptable approach. It’s just another manifestation of anti competitive behaviour and the power and money you can get by “free” software.






  • So the way evolution works, the design we have works well enough that it doesn’t cause problems. It might be the best possible design or it might not, all that mattered is that whenever it arose in evolutionary history it was either an advantage over what camebefore in terms of survival so propagated or it was not detrimental and paired with something else genetically that propagated.

    We can’t definitively answer your question but we can speculate on why it’s a good idea to separate urine and faecal matter. Urine is a reasonable medium for growing bacteria. That wouldn’t matter in the colon but would matter if bacteria from the colon could ascend into the kidneys and diarupt it’s function. Valves could help or a bladder that drains into the colon, but complete separation may just be better.

    It may also be that the acidic nature of urine would disrupt the helpful bacteria we rely on to colonise our guts to help digest foods.

    Another possibility is the constant flow of urine would mean our faecal matter would never dry out. It’d be like having diarrhoea all the time and we’d need to poop constantly. The colon retrieves enough water - but not all water - that’s why poop isn’t hard as rock. If it was flooded with fluid it may not need to retrieve fluid.

    The fluid might even be stuck in a cycle between the colon and the kidneys and make it harder for the body to keep homeostasis - as the kidneys excrete more fluid to try and regulate fluid volume the the colon could just resorb it. Basically the colon could end up working against the kidneys and cause even more work for thenl body. It may just be less efficient than discarding water as needed.

    Drier faecal matter in the colon and a reservoir of fluid in the bladder does also give us freedom to release when it is safe to do so, which may protect us from predators (having to stop to poop even a few times a day is dangerous compared to only going when you know it’s safe to as there are more opportunities to be attacked by a predator). It would also be very easy to track an animal that leaves a constant trail of poop and urine uncontrollably behind it.

    All or none of these may be reasons why we have separate urinary and alimentary tracts; it’s impossible to know and would always be speculation. But regardless these do seem like reasonable reasons why we may have separate tracts.



  • This is the problem with believing too much in models. A model can show you anything you want - it’s output is only as good as the parameters and algorithms you set it.

    Modelling the climate in the next 50-100 years is already extremely difficult and fraught with inaccuracies but we have lots of models and data to extrapolate from, so we do have a crude idea where we’re going. But we can’t model next years weather with accuracy, just the base trend. Crucially important warning for climate change but limited otherwise.

    Modelling out to 250 million years is basically a crock of shit. The tectonic movements are predictable and gross predictions that a pangea arrangement might be warmer may have some validity but modelling the climate and evolution and status of mammals is pure conjecture.

    Good thing about modelling that far is you will never have see you model’s accuracy being tested. Publish a paper, play into current fears around climate change with an irrelevant prediction about 250million years away, get an article published in the New York times and egos massaged all round.
