<p>Great article. I particularly enjoyed the approach to creating gibs.
Although it was a tech demo, I created something like this around the mid 90s. One thing I did that I don't see mentioned in this article was I used 8x8 (or 16x16) light maps on the textures, which allowed me to easily have things like flickering torches and rockets that lit up the hallways as they shot down them. Lightmaps can also be used to "bake in" lighting if desired.
Since the light map is "only" 8x8 you can afford to do some math on each luxel (each unit in the light map) to calculate distance and line of sight to light sources to determine a brightness value. When rendering the texture, the luxel was used with a lookup table to determine the actual color of the pixel being drawn. The light maps were updated 15 times a second if I recall correctly to help performance. Thanks to DJGPP, I was using inline assembly for the rendering. Since floating point math was slow at the time I used fixed point math which optimized well. The rendering was surprisingly performant on computers of the day.</p>

<p>To install Windows 11 with a local user and/or to install it without the TPM 2.0 requirement, what I found easiest was using Rufus to prepare a flash drive with the Windows 11 ISO. Rufus asks if you want to create a local user and what the user name is. It also asks if you want to skip some of the Windows 11 requirements. Then when you install Windows 11 using the flash drive it just works.</p>

<p>Install the browser extension Unhook. It hides all recommended YouTube videos, so when you watch a video you aren't looking at a bunch of other videos to watch. It's very customizeable, so you can choose what to hide.<p>Create a list of what you want to be doing and consider attaching it to your monitor or putting it just to the side so that you can easily look at it. When you feel stuck, look at this list and do something on the list. Ensure the list includes some easy to do things on it like maybe "go for a walk", "read a book", "play instrument" etc.<p>When trying to change habits, start off small and simple. For example, if you want to start running each day you might start by putting on your running shoes and walking to the end of the driveway and back. Start off so small that your brain can't talk you out of it.<p>I create daily todo lists and feel satisfaction from checking them off.<p>Try some ideas and see what works for you. Good luck!</p>

<p>I gave Firefox a try for a month, but ran into enough issues that I ended up switching back to Chrome about a week ago. Here are some of the problems I encountered that I can recall at the moment and doesn't include the many issues I managed to fix:<p>Copying content doesn’t always work on certain sites. For example, you can't copy an image from Photopea.com, which I rely on frequently. Saving the image to a file instead slows down my workflow too much. This is a known bug which has been around for a long time.<p>Password autofill was inconsistent. It didn’t work on some sites, like when accessing a Pi-hole dashboard. Maybe there’s an about:config tweak to fix this, but by that point I had already spent a lot of time troubleshooting other issues.<p>The bookmark menu closes after opening a single bookmark. If you like opening multiple bookmarks in a row, you have to keep reopening the menu and navigating to the next one each time, which is frustrating.<p>Twitch videos loaded slowly. I managed to fix this by deleting a specific file, re-creating it as a blank file, and setting it to read-only. This appears to be a known bug the developers are aware of.<p>Loading custom extensions is inconvenient. You can only load them temporarily unless you launch Firefox with a command-line option for each extension.</p>

<p>If this case reaches the Supreme Court, one key consideration is the potential pressure to support the growth of U.S. AI companies. Rather than imposing strict legal restrictions that could hinder their ability to compete globally, especially against companies in countries with more lenient regulations like China, the Court may be inclined to take a more permissive stance.</p>

<p>I'm no coffee chemistry expert either, but the following article indicates that the main adenosine receptor antagonists are caffeine, theophylline, and theobromine, all of which are found in coffee, tea, and chocolate (<a href="https://en.wikipedia.org/wiki/Adenosine_receptor" rel="nofollow">https://en.wikipedia.org/wiki/Adenosine_receptor</a>). These three are all considered purines and therefore molybdenum would be involved in breaking them down. All three also have a diuretic effect (1) and Theobromine "shows strong diuretic effects" (2). That leads me to wonder if the ratio of these three varies significantly between coffees. I'm not sure but found one paper that shows that it does in cocoa (3), so perhaps it does in coffee also (there's probably research on coffee about this and I just didn't look hard enough).<p>(1) <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4383091" rel="nofollow">https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4383091</a>

<p>I took 1 mg of molybdenum daily for about 3 weeks and then tested out drinking coffee. By this point I had tried many other interventions that did not help. I wasn't expecting the molybdenum to help but figured it was worth a shot since it was about $6 for a bottle. After the fourth day of drinking coffee, it was clear that something had changed; the coffee was no longer the issue that it had been. I'm now able to enjoy a regular coffee in the morning without any negative issues. I didn't change my diet or supplements during this time or anything else I can think of that could possibly have contributed to this change.<p>When I was sensitive to coffee I felt just wrecked and exhausted by the coffee. I couldn't sleep well at night. Several days in a row of drinking one coffee in the morning and I'd get to the point where I would wake up feeling jittery the next day. Now, this is completely resolved.<p>My blood tests for commonly tested health markers such GPT and GGT have always been fine and tend to be tested about once a year. I had the coffee sensitivity for quite a few years until recently when I finally resolved it.<p>I do have some minor gut issues, so I'm guessing this is to blame for any nutritional deficiencies (I eat a healthy diet of "real" food).</p>

<p>There are stimulating compounds in coffee other than caffeine, so I've pondered that people who find decaf stimulating may be reacting to some of these other compounds.<p>Another consideration is that people seem to often report that coffee is more stimulating than caffeine pills, even if the amount of caffeine is similar.</p>

<p>I'll add some more info to my post.<p>Caffeine is a purine (<a href="https://en.wikipedia.org/wiki/Caffeine" rel="nofollow">https://en.wikipedia.org/wiki/Caffeine</a>).<p>A Google Scholar search for "molybdenum purine" will come up with many studies discussing how molybdenum is involved in purine catabolism. For example, the following article states "[molybdenum] is considered essential because it is part of a complex called molybdenum cofactor that is required for the three mammalian enzymes xanthine oxidase (XO), aldehyde oxidase (AO), and sulfite oxidase (SO). XO participates in the metabolism of purines". (<a href="https://aspenjournals.onlinelibrary.wiley.com/doi/abs/10.1177/0115426593008006277" rel="nofollow">https://aspenjournals.onlinelibrary.wiley.com/doi/abs/10.117...</a>).<p>When I was younger I was able to drink multiple pots of coffee in a day and even drink coffee right before going to sleep without any obvious issues. So when I couldn't even drink a single cup of coffee in the morning on a regular basis without problems I had reason to believe there was something wrong with me and it wasn't simply a genetic quirk.</p>

<p>I had a similar problem. Coffee, decaf, even dark chocolate would be very stimulating and would mess with my sleep, even a single cup in the morning. I tried quite a few things to solve this and ended up discovering that supplementing with molybdenum solved it. Molybdenum is an essential element important in the metabolization of some compounds, including caffeine. It's cheap and may be worth trying.<p>Also, I found that L-Theanine helped but only for maybe a week or so before it became less and less effective. For me, it was obviously a band-aid solution that wasn't correcting the underlying problem.</p>

<p>Every time I try Krita I bounce off of it because the controls are too different from Photoshop. For my relatively simple use cases, Krita could be a replacement for Photoshop, which I've been using on and off for roughly 30 years. The muscle memory runs deep. Just something simple like holding alt to toggle the magnifying glass between zoom-in/zoom-out doesn't work in Krita and the configuration doesn't allow for this.</p>

<p>The article mentions this, but housing is so much more expensive now that it's by far the largest cost for some people depending on where they live. For example, my father's first house was less than 2x his annual income. Now, in the same city, a similar house is about 17x the annual income of someone working a similar job. Even a small condo is about 8.5x.</p>

<p>Here's my personal experience switching from Plex to Jellyfin. Everyone's needs are different, but, for me, Jellyfin has been a much better experience.<p>I used Plex for years and always hated it. It didn't let me customize the home screen in the way I wanted, so there was always a bunch of junk on there that I didn't want and couldn't remove. It also ran very slow on my Samsung TV (1), starting up slowly and responding to the press of a button after about a full second (it had done this for a long time through multiple versions of the app and factory resetting the TV without any improvement; also, the TV is only a few years old).<p>I got frustrated enough to finally switch to Jellyfin about 4 months ago. It was a pain to get the app installed on my TV (the app isn't in the TV's app library, so it needs to be installed as if you're a dev), but once I got it working it works well. The app starts up faster than the Plex app and is very responsive to button presses.<p>Back when I was using Plex, I really wanted to customize the home screen to remove certain components and re-order what appears and spent a lot of time reading over settings/customization stuff which never actually let me do what I wanted. With Jellyfin, I simply went to settings > home and the intuitive options there let me do exactly what I wanted to do in seconds.<p>I can't think of any major issues I've had with Jellyfin, but here are a couple of thoughts. With Jellyfin I needed to create separate folders for what what Plex called collections and add them as libraries instead of collections. At first, I thought this was a negative but ended up deciding it didn't really matter as it works fine. I had a series of videos that wouldn't play properly on Jellyfin until I used ffmpeg to strip out the extra subtitle tracks (they had 42!), but never tested them on Plex so not sure if Plex would have handled them.<p>(1) I will never buy another Samsung TV, but that's a rant for another post. I considered buying an Nvidia Shield just to fix some issues with the TV, but probably won't bother now that Jellyfin is working well.</p>
