<p>I think I get your point. It's cruel to require Kafkaesque testing and that just makes it not worth it try. But too simple of a test can also misdiagnose.<p>The chance to be diagnosed with an appropriate gate varies greatly based on where you live and which doctor you can see and more. It can be anything from a 5 minute conversation, to 6 months of inconvenience, to no chance of even existing in your lifetime, to suck it up and don't ask because your career will end.</p>

<p>I want to add that the comment is also funny to me because it and the blog post are very relatable to me. I don't mean to dismiss it at all. It's really important to get a good diagnosis for anything like this and not dismiss it or lock into the wrong diagnosis because of your own tunnel vision.<p>You wrote "the test is quick, easy, and painless" but I also want to note that it's not always. Depending on your country, parents, specific doctor, etc it can be very difficult to get a proper diagnosis and help. In some places a big criteria is diagnosis during childhood so if you're 30 or 40 you might have no chance. Or a chance but it depends on your parents retroactively answering a questionnaire, or finding an old report card with the right words.<p>As you said it's life changing to get the right help and I encourage everyone to pursue this.</p>

<p>I have a question (and please take it in jest)! In between buying a telescope, seeking out an opinion on ADHD, accidentally hacking an online test, and then blogging about it, how many things on your todo list(s) did you not do?</p>

<p>This comment is so funny to me, because I imagine you being distracted to make the comment before making it to the end where the psych did indeed review the new results.<p>Well I only know that because I skipped to the end. Then, while scrolling up I realised I missed the whole side-quest about promising to not cheat the test again, taking the test again, but then "accidentally" finding an exploit the system, and then cheating the test again, but this time cheating even more to see the results.<p>Then, scrolling up more I see that this whole thing started with seeing stars and then buying a telescope on amazon (probably at 3am).<p>And here I am commenting on HN instead of replying to an email...</p>

<p>I agree, today it's like having one of the latest Mac Studios, one older Mac Studio and a couple of MacBooks. Or even just one maxed-out Mac Studio. Enviable but credible.</p>

<p>I find it weird that in specific cases it's such a huge effect yet most of the time I can't notice it. Once when I got a new prescription I googled why the X in the red circle icon for closing a window is so off-centered, but it's just a case where chromatic aberration is really noticeable.</p>

<p>Me too, I always have a dongle and an ethernet cable just in case but this removes the need for a cable (I always have 2+ usb-c cables). I've also just found something similar for HDMI, also removing the need to carry an HDMI cable. Trying to think of more things, not sure why I didn't think of searching for these before because I have made something similar for the console serial port connector for raspberry pi and Jetson boards.</p>

<p>Inductance coils (usually inside the RJ45 jack itself) are what provides isolation. They are made from very thin wires so if something goes wrong this is the first and hopefully only thing that will break. If you apply enough voltage of course you can break things beyond this.</p>

<p>What a clever idea. I carry an ethernet dongle but this one is just the male end and a female usb-c port, meaning your existing usb-c cable is useful and you don't need to carry an ethernet cable.</p>

<p>Depends on the device, in principle if both have thunderbolt and you use a thunderbolt cable it should work. I've done it between 2 macbooks many times.</p>

<p>Ethernet is electrically isolated at every port (unless you really go out of your way in to design it otherwise in an internal design). Your advice is still correct but it's more about lightning or something gone wrong, it's not an immediate risk.</p>

<p>I've been doing this for years between MacBooks with a thunderbolt 4 cable. It's very fast and unlike 10Gbps ethernet, doesn't require a bulky, power-hungry[1] adapter.  MacOS also will use thunderbolt automatically for Migration Assistant if available.<p>[1]Most people don't realise how much power ethernet consumes. Even 100Mbps ethernet consumes about 0.5W per port and it goes up with higher speeds.</p>

<p>In Europe a class 1 ebike can't have a throttle and assist must be limited to 25km/h (it's 32km/h in the US). They can be faster and have a throttle, but then they are more like scooters in terms of licensing and insurance. If you go to most bike shops in Western Europe they will only have class 1 e-bikes. A class 1 bike is generally allowed everywhere a bike is.<p>While there are a lot of people riding more powerful bikes in Europe illegally, at least some countries are trying to crack down on them. In the US, it seems easier to buy class 2 and 3 e-bikes, and there seems to be a higher proportion of illegal bikes. It's an open secret which "class 1" bikes you can buy and then overclock easily.<p>So in Europe you mostly have class 1 e-bikes and obviously illegal (as in you can tell just by looking at them), but in the US you have these plus a lot of class 2 and 3 e-bikes, and overclocked class 1 e-bikes. The end result is most mountain bike trails in Europe allow class 1 e-bikes only, but in the US it's impossible to enforce class 1 only, so a lot of regions are trending towards banning all e-bikes from all trails. So be careful about wishing for a more powerful e-bike you can drive in traffic and mountain bike trails.</p>

<p>A similar law in the US exists to prevent non-food being put inside food. It's why kinder surprise is banned in the US. It's not because Americans are "too stupid" to avoid choking, it's because the rule already existed and there's not really a good justification to change it for the sake of a foreign candy company.</p>

<p>I was surprised to see a real reference because I thought the 100% beef thing was a 100% myth.<p>But that article confirms in several places that independent testing finds no fillers at all, and what is left is just "Plaintiffs allege that undisclosed processing steps or agents applied during production or cooking could alter the accuracy of the “100%” claim." It's not a very convincing argument and it would be quite hard for McDonalds to cover up a secret process to add another ingredient.</p>

<p>Quake came out just before I started high school and I played it a lot in those three years. I remember playing quake 1 in the LAN in university around 2002 because it was easy to share the 50MB of portable files. Things moved so fast back then that it already seemed like a retro game. I didn't realise at the time that it was a timeless classic and I would still be playing it 25 years later.</p>

<p>It's a great store. It's similar to Ikea in that you can go in without doing any research or shopping around and be reasonably sure that whatever you buy from one of their own brands, at any price point, is better quality than the same price point somewhere else. For camping stuff especially, the value is very good. The higher end might be missing but that's almost a feature for the average person to go in and choose from a good or pretty good option.</p>
