<p>I guess jaywalking stuff makes this harder? Because in the UK for example, roundabouts will often be surrounded by marked areas for pedestrians to cross, but they are not proper crossings. You don't have to wait or expect traffic to stop for you, you just walk across when it's clear.</p>

<p>This is just going to become another way to lock developers into UE. Then they will start charging for licenses, same as Unity did for its versioning feature. It might be open source but that doesn’t stop the commercial use of it being charged for.</p>

<p>> Don’t RMA it, and don’t solder it yourself. A local phone-repair chain with a microsolder tech can put a 3 mm SMD part back on a GPU PCB in twenty minutes for the price of dinner. The skill is in your city. You just have to look.<p>The trouble with this though is, what if that is not the only issue with the card? That’s normally my thought process on reaching for RMA. The unit could be an all-round lemon that should not have passed QA etc. (and as noted in the post itself, working for a week on various tasks is not enough to prove it good)</p>

<p>> However, having had much success with experimentation so far I decided to try something that would probably work: I copied the code from the magazine into Notepad and saved the file as .exe instead of .txt.<p>Glad to hear I’m not alone in these kind of early experiments. I remember having no idea what the concept of programming actually was, and opening game EXEs in notepad to try and understand how they worked. The demo of Majesty was one I particularly wanted to modify and had no idea how</p>

<p>Yeah well I was imagining how medical ethics work with respect to putting patients through unnecessary suffering. Temporarily restoring someone’s lucidity with the knowledge they will lose it <i>again</i> (having already suffered the progression of the disease the first time) is more helpful to you than it is to them</p>

<p>The problem with this study though is that it doesn’t really illuminate anything. Psychedelics restoring the default mode network in the brain is already somewhat understood (*that it happens, not the mechanism of how), so it’s not that strange a temporary reversion of the symptoms of Alzheimer’s would happen.<p>And it’s not even suggestive of eg making an actual medicine that could be taken long term, because Alzheimer’s physically destroys your brain. The restorative effect of psychedelics is just a bandage over not understanding why that damage is happening in the first place.</p>

<p>Yeah this story was on HN before a few weeks ago and I raised similar - it’s nuts to give that to someone who probably doesn’t have the mental state to be able to comprehend what is going on. Don’t understand how it is possibly ethical to do.<p>Especially with the effects being temporary - can you imagine how awful it must be to <i>regain</i> lucidity outside of your control and then lose it again for the sake of an experiment like this? Awful experiment.</p>

<p>One advantage that does come to mind in light of the Iran war (and the loss of an AWS DC) is difficulty in attacking it, even when it’s directly above foreign territory. I wonder if one of the intended customers will be gov/military? Conjoined spy satellite/DC for some function maybe?</p>

<p>> First of all, structs aren't used so you don't have to invent names for them (e.g. there is no IntVec)<p>But since it’s storing a void pointer any way, they wouldn’t need separate names right? You could use one struct everywhere regardless of the type of the items<p>Which IMO is a better idea than using an array here because the fields can be properly named and typed to prevent accidental misuse</p>

<p>The need to tap a bunch of discredited UK "scientists" to get the anti-mRNA perspective on the testimonies, should perhaps be an indicator that this viewpoint is not really credible (they couldn't find enough reputable doctors inside of the US willing to testify the same thing).<p>Incidentally here's a really nicely written counter to many of the claims Malhotra has made:<p>> Equally, evidence that mRNA vaccines cause cancer is simply untrue. This sentence, for example “The millions of molecules of mRNA entering the cell is creating biochemical havoc, is disrupting protein metabolism, is interfering with tumour suppressor genes” is meaningless pseudoscience. There is no credible evidence that these vaccines disrupt tumour suppressors or drive any kind of process (biochemical or otherwise) that results in cancer. It is particularly crass to try to link this pseudoscience to the unfortunate incidents of cancer in the royal family and is reminiscent of the ‘died suddenly’ trope which attempted (and ultimately failed) to link the death of any young person to their vaccination status. This kind of outlandish conspiracy theory only serves to undermine the credibility of those spreading it.<p><a href="https://www.sciencemediacentre.org/expert-reaction-to-claims-in-speech-made-by-dr-aseem-malhotra-at-the-reform-party-conference/" rel="nofollow">https://www.sciencemediacentre.org/expert-reaction-to-claims...</a><p>(the sentences being cited are from a different source but it's the same kind of story he tells in this testimony)</p>

<p>> Really though, weren't you the one conflating mushroom dosages with those of pure psylocibin a moment ago?<p>I think you’ve misunderstood. I was quoting the paper, which states 5 grams. 5 grams is a lot of mushrooms, especially for someone who is not compos mentis. 5g <i>implies</i> probably  ~50mg of psilocybin, I haven’t been conflating them at all (you measure the amount of mushrooms because obviously you can’t see how much psilocybin is in each one).<p>If the paper stated an exact dose of psilocybin this would be a totally different discussion<p>Edit: I just realised the quote in my first comment incorrectly states 5g psilocybin- I didn’t ever understand the paper as meaning that, I just wrote that incorrectly. All of my subsequent comments were talking about this as 5g mushrooms - which is still a heavy dose!</p>

<p>I’m assuming you’ve never taken mushrooms before (on average there is probably ~10mg psilocybin per dried gram, so 5g is 50mg which is on the high end of dosing, definitely not ‘standard’)</p>

<p>The dose in the paper is 5 grams, not mg<p>> Second, you think it’s more ethical to let a patient suffer? Are you against emergency surgeries where a patient is unconscious after a car accident?<p>My concern is that this induces more suffering. They are going to gain lucidity and then lose it again. That must be deeply distressing (for the family/relatives too). Can’t imagine that psychedelics help with the state of psychosis/hallucinations that advanced Alzheimer’s patients already experience too</p>
