I'm a newly retired 60-year-old, with a 76-year-old spouse. This is really hard sometimes!

I'm trying to stay active in my non-profit, non-commercial endeavors, but I'm finding myself with more time on my hands than I know what to do with.

How you doing?

First and foremost: I'm not certain whether this belongs in ~hobbies or ~comp. As I consider this a hobby, this seemed like the more appropriate spot, but I'm more than happy to move/repost in ~comp.

So for the past few years, I've really been hit by the computer nostalgia bug. It originally started as me just wanting to dive back into MUDs, and the whole retrocomputing fascination probably came from me wanting to recreate the "good ole' days" where I would pull up the Windows 98 terminal app and connect to my favorite MUD.

Now I've got a room in my house dedicated to this old, esoteric hobby that happens to take up a lot of space. Admittedly, I don't know a TON about hardware but I've been having a blast tinkering around on old machines. It's even more fun to see how I can push the limits of the computers given a few modern tweaks here and there.

Here's what I've currently got sitting up in the Upstairs Museum of Retrocomputing:

• A Compaq Prolinea 5/75 Pentium - this was given to me by a friend who had it sitting in the basement. To my surprise, everything was still in working order and it fired right up (Windows NT 4.0!) on the first try. Of course, I ripped out the old barrel clock battery and put in something safer. I'd say I tinker with this one the most on the software side, while still trying to keep the hardware as close to original as possible.
• A Compaq Prolinea 3/25s 386 - I just picked this bad boy up and am working on getting an OS installed. It had some damage from a leaky clock battery but I don't believe anything was irreversible. I'm not too confident in the whopping 4 MB of memory, but I'm planning on installing Windows 3.11 on this one.
• A Tandy TRS-80 CoCo 2 - It works, but I haven't spent a ton of time with it because I don't have an old TV or monitor with a coax connection. I'd love to figure out how to create my own cartridge with a homebrew version of Zork or Adventure.
• A Power Mac G5 - It's not ancient, but I think it's still worthy of being in the museum. I haven't had a chance to play around with it yet because I don't have the right video cable. I'll get around to it eventually.
• A Generic Pentium 4 - I actually found this one at a Goodwill store. This one fired right up and had a copy of Windows 2000 installed, including all of the old work files that the person left intact. This one has been the easiest to mod because it's somewhat closer to modern and uses a common form factor. So I've plugged in a new OS, new ethernet, etc. At some point the technology starts to blur and you start questioning why you aren't just using a modern computer.

What's next on my list? I'd like to start playing around with computers/OSes that I'm unfamiliar with. I grew up in a DOS/Mac OS 7-10/Windows world, so I'd love to get my hands on a NeXt, BeOS, etc. or even an Apple II.

But first I need to get the damn 386 running again.

Having finished out the Amazon Prime series "The Expanse" I'm now working my way through the novels and I keep coming up against a problem with with railguns. Specifically, the way that railguns are used in The Expanse doesn't mesh well with the way they're portrayed.

First, some background. Ships in The Expanse are generally unarmored. There are a bunch of reasons for this but the short version is "most things that can hit you in space will kill you anyway" and armor adds mass which makes every manuver more expensive in terms of reaction mass. So no one has armor. This is important because it means that ships in the Expanse can get ripped up by something as mundane as a stray bullet from a Point Defense Cannon (PDC). PDCs are... well, they're guns. Regular guns which are flinging around much less mass and at much lower velocities than railguns.

Thus, ships in the Expanse are equipped to handle impacts but nothing much bigger than a sand-grain moving at a few km/s.

When we're introduced to rail-guns in the series we're given to understand that they use magnetic acceleration to chuck a 5kg chunk of tungsten and/or uranium at a target at an "appreciable percentage of C." That's much faster than a bullet or any micrometeors ships are likely to encounter. Even 1% of C is ~3,000 km/s.

5 kg of Tungsten is less than you think. Some back of the envelope math suggests that's about cube about 2.6 inches on a side... which is not big. That works out to an incredible energy density which would make a lot of sense if railguns were routinely being fired at planets or asteroids but, since they seem to mainly target ships, the vast, vast majority of the energy that goes into flinging that slug at its target is going to carry through to the other side of the ship.

All total we're talking about 488.5 million Newtons of force for 1% of the speed of light. Helpfully, this scales roughly lineraly so long as we don't get too close to C and induce relativistic mass issues, so 10% of C is 4.8 billion Newtons and so on. So, that railgun slug is carrying a lot of energy. At 1% of C it represents 22.5 trillion joules of kinetic energy. Written out long-ways so we can appreciate all those zeros it's 22,500,000,000,000 J. At 10%, we're talking 2.25 quadrillion joules. To give some sense of scale, that means that, at 1% of C, three rail-gun slugs are delivering about as much energy as the bomb that destroyed Hiroshima in 1945. At 10% of C one round carries about 537 kilotons, or about the yield of a modern, city-busting hydrogen bomb.

Those are absolutely titanic amounts of energy but, realistically, they'll never deliver that much power to a target. After all, a railgun round can only push on its target as hard as the target can push back on it. If the round just punches through the entire ship like it's made of paper, most of the energy stays in the railgun slug as it exits the other side of the ship and you get a neat hole rather than a gigantic flash as trillions of joules of kinetic energy turn into heat.

And obviously, if we're trying to kill things, we want the latter. The solution to this problem is fairly obvious: you need fragmentation. While it's great to have a tungsten cube all tightly packed together as you accelerate it, if you're shooting at a ship, you want a fairly diffuse impact, especially if we're talking about a 10% of C railgun slug. There aren't a lot of things out there in the solar system which can take 500 kilotons of hate and come out the other side in one piece. Moreover, at the distances at which a rail-gun fight happens, that spread would help ensure that you hit your target. Like a shotgun loaded with birdshot, a fragmenting railgun round would provide a cone of impact rather than a line, making dodges less effective.

And, as I mentioned earlier, you don't need a ton of mass to make this work. If a PDC round can go straight through a military craft then we can safely assume that a chunk of tungsten with the same kinetic energy will do the same thing. PDCs look rather a lot like the close in weapons systems in use on many naval ships today so we'll use those as a guide. The 20mm cannon on a Phallanx CWIS tosses out rounds at about 1,035 m/s. Those rounds weigh about 100 g (0.1 kg) which gives them a kinetic energy at the muzzle of 53,422 J.

So, if we could predictably shatter our 1% C railgun round into 421,136 pieces, each would have about the same kinetic energy as a PDC round and be able to hole the ship. At 10% C we could go even smaller and do the same thing with upwards of 40 million shards. 1% is plenty though. Each hull-penetrating piece of our original 5 kg bullet needs only weigh about 1/100th of a gram, which works out to being about 1/100th of the size of a grain of sand.

Put another way, if the fragmentation of a rail round could be precisely controlled, a target ship would experience hundreds of thousands of individual hull breaches with the mean distance between them determined only by the geometry of the ship and the angle of the attack. The result of this would be either the delivery of a titanic amount of energy to the ship itself as the armor attempts to absorb the impact or, if no armor is present (as seems to be the case in the Expanse) the rapid conversion of the interior of the ship to a thin soup.

This, however, seems never to happen in the series and what leaves me scratching my head. As a book and TV series, The Expanse does an otherwise bang-up job with hard science fiction. Most things in universe make sense. This, however, does not. We have take as a given that the materials science technology exists to allow the mounting and firing of a railgun on a ship -- there are a lot of challenges there -- but the straight-line-of-fire use of them is a rare problem with the world-building.

Any fans have any suggestions to help me square this circle?

I went through a phase where we seemed to have board games nights with friends a couple of times a month but with the whole pandemic thing that has dried up.

Tonight, I finally got around to trying Lanterns with my wife and we really enjoyed it. It's sort of similar to sushi go with more steps. You play lake tiles which contain lanterns and collect lantern cards based on how you place the lake tiles, then you dedicate those lanterns in different sets to gain honour (points) and at the end, who has the most honour wins.

I'm looking for the simplest possible marinade recipe. Something with very few ingredients that will work on any cut of meat.

My plan is to use that as a base and learn to modify it based on the meat, dish, and flavor profile I'm going for.

We're at 59 days until Gencon and its one of my favorite events of the year. Wondering if anyone else is going and what you're excited for.

It seems like Lorcana is set to the be the buzz of the con this year around. While I'm interested in getting my hands on a deck or two to give it a go, I'm more looking forward to when BGG posts their games that will be releasing to sift through and try to find a hidden gem or two.

I’d really appreciate suggestions for any action-packed anime series you might be able to share.

I “play” Zwift indoors for exercise when I don’t have time to ride my bicycle outside. While Zwift is a huge improvement over nothing, I still find myself watching the clock more than the screen. To help keep my mind busy and pass the time, I’ve been watching anime while riding indoors for the last several years. The more intense the anime, the better!

I think the early Attack on Titan seasons are the most emblematic of what I’m looking for, though I’ve been enraptured by other less likely shows, such as Psycho-Pass and Dr. Stone.

Chainsaw Man, Blue Lock, Shield Hero, Sword Art Online, Parasyte , the first season of Vinland Saga, Shokugeki, and many others have helped me get through countless hours of riding in the past, and I could really use a few new series going forward.

Thanks in advance!

I know a lot of people have been asking for an app, if just for a home screen/app drawer icon, so I cobbled together a small WebView wrapper that installs on your phone as an app.

It's for Android only (sorry iOS users) and probably will receive very little support, since I'm not an Android developer! In fact, this is just a fork of the vastly more capable woheller69's gptAssist, ported over to support Tildes and with some limiting functionality removed. Absolutely check out some of their stuff! My app and the original gptAssist are both licensed under the GPLv3. If anyone would like to contribute, please do! In fact, if you're an Android dev, feel free to fork and make it much better.

I absolutely appreciate the design philosophy of the Tildes devs and think that a WebView wrapper is a good compromise between having an app and using the thoughtfully-built website. If you're anything like me, you just like being able to tap on an icon to get to where you're going. I put this together with that in mind.

I've been playing ARPGs since Diablo 1 and have over a thousand hours in PoE, was wondering what everyone thought of D4?

I think the slower gameplay is a fun change of pace and that the legendary affix system is an elegant solution to always making drops interesting.

Surprisingly, as much as I didn't really care for D3, it's game feel was excellent. D4 has taken an odd step back in that regard. In D3 when you bashed an enemy to death with a barbarian they flew across the stage, or melted into a pile of goo if from poison. D4 everything feels kinda bland visually during combat.

Excited to see what end game is like, still only level 35 so we'll see how this so scales later on.

Thoughts?

Some of my favorite experiences on Speztopia were forged in and throughout the DimensionalLeaping/Jumping/Shifting subreddits, where I quickly came to understand and appreciate a variety of methods and principles underpinning the idea that our conscious experience is only part of the equation (and yet, at the same time, is all that there is). Such thoughts as "we are all collectively dreaming one another into existence," "advaita vedanta nondualism and its implications," and other notions were uniquely inspiring to me.

I began to have experiences of my own, when I meditated on the Oneness that had been revealed to me. There were instances where I would wake up and realize that minor things in my everyday had been altered subtly. One morning I had a very vivid dream (or perhaps, a true experience--because what really is the difference?) of witnessing my own death. It was somewhat traumatic, if I'm being honest. But I arose following that incident and realized that the hot and cold water knobs at my sink had changed seemingly out of nowhere. It was also the case that a close friend of mine and I were suddenly no longer in an argument, despite it being a rather trying and difficult situation--he had no memory of it having ever transpired, and insisted I was making things up. There were other small things like that, that I began to notice as I wandered around my college campus. Events that I vividly recalled attending had never happened, or were about to happen the next day.

I had made what I knew then to be a "discontinuous breach" or an acute dimensional shift, an abrupt and often confusing repatterning of a worldline in ways that is not congruous or otherwise defies certain expected patterns/physical laws/metaphors. This is compared to a continuous breach, one that occurs in ways too subtle to recognize, in a series of understandable and acceptable steps, or otherwise in keeping with the established order.

As I have grown in my experience and understanding of nondualism, just as I have gained some answers, I find that ultimately I am left with ever more questions. I think others who participate in intentionally weirding one's quantum consciousness know what I'm talking about.

I wanted to start the conversation here in the hopes of a sustained community discussion about and around these ideas. TriumphantGeorge, if you're here: Your tutelage and constant availability for bouncing ideas off of was nothing short of heroic, in my mind. I still number you among my mentors and appreciate so much the time and effort you took to open my mind to a whole new way of thinking. Being strictly dualistic throughout my childhood, learning that there was another way of conceiving of things opened countless doors in my life.

An open question in addition to an invitation to share: What are your favorite methods for astral projection? I find that I am somewhat resistant to most elementary or straightforward projection techniques, so the more complex and systematic, the better!

I recently decided to start using RSS to curate interesting news as I feel I am being overloaded with Clickbait from all directions when I am looking for the latest news or updates on Google. I'm looking for some good sources for Tech or Programming Articles or news that aren’t just clickbait and have good informative content.

I currently have BBC News, Krebs On Security and Ars Technica, does anyone have any other website suggestions which are worth subscribing to?

This is probably bad form but here goes.

I have just posted about the Man vs Horse race that happens in Llanwrtyd Wells, Wales on an annual basis and it got me to thinking, is it a UK idiosyncrasy to have silly sports or is it World wide?

Apart from Cheese rolling at Cooper's Hill (https://www.youtube.com/watch?v=PdKRx30s6sk) and Shin Kicking (https://www.youtube.com/watch?v=rajJJaiEdPE) what other silly sports are there?

I'm interested in buying one of the new PC gaming handhelds, and I'm torn. If I went for the Steam Deck I'd be buying the 512GB version, so the price difference between it and the ASUS is only about £50/£100 more. The ASUS seems to do a lot better in benchmarks, has a nicer screen, and comes with Windows 11. I love Linux but there's several games I'd want to play on it that the anti cheat just won't work with Linux. I know you can dual boot the Steam Deck, so that could also be an option. The main thing that is making the decision more difficult is that the Steam Deck has touchpads, and the ASUS apparantly has inferior thumbsticks and D-pad. But then again the ASUS is sleeker and lighter, so potentially more portable? Sorry for the ramble, I just wanted to express my thoughts so far, and hear what you all think. Help me decide!

So, quite a few people don't like/watch video content, and don't like seeing the homepage filled with videos. Let's try something new, see if it sticks.

What are the best videos you have watched this past week/fortnight?

I've recently gotten into Too Many Bones.
I've been into tabletop for years and painted many minis, but now I find myself floored by hoplomachus and too many bones...and there's no minis to paint. But the gameplay is so so good I'm in love.
I'm waiting on unbreakable to come in. All I've played is undertow but man is there a lot going on in such a small box.
What's the best gearloc?

This thread is posted weekly - please try to post all relevant US political content in here, such as news, updates, opinion articles, etc. Extremely significant events may warrant a separate topic, but almost all should be posted in here.

This is an inherently political thread; please try to avoid antagonistic arguments and bickering matches. Comment threads that devolve into unproductive arguments may be removed so that the overall topic is able to continue.

Not sure if this is already a feature, but I think in keeping with Tildes's philosophy of letting the platform grow (to whatever extent that it may) sustainably, there should be a waiting period of a couple days to a couple weeks between when a new user joins and when they can generate invite codes. This to me seems like an effective way of preventing viral growth and allowing the community to recalibrate or "get a grip on itself" after any new influx of users.

What have you been watching and reading this month? You don't need to give us a whole essay if you don't want to, but please write something! Feel free to talk about something you saw that was cool, something that was bad, ask for recommendations, or anything else you can think of.

If you want to, feel free to find the thing you're talking about and link to its pages on Anilist, MAL, or any other database you use!

What kind of setup/equipment do you have? Preferred roasts? Maybe you don't have equipment, but a favorite drink or place?

My setup isn't anything special, but it works for me. I have an Expobar Office Lever that I bought in 2017. Daily use and a bit of minor maintenance along the way, and it's been a solid machine. Paired with a Quamar M80E grinder.

Also have a second, more entry-level machine at our cabin - Gaggia Classic Pro (which is having some issues right now) and a DF64P grinder.

For beans, I've been using a subscription from Bottomless for the last 1.5 years and have been super happy with it. I enjoy trying different roasters from all over the country and the service has been super reliable and not all that expensive for the fact that you get just-in-time freshly roasted beans at your doorstep.

Anyway, what are you guys drinking?
