The internet is a very diverse place but sometimes with the "default" north american skew, it may not seem like it.

If your culture or people or faith group or spiritual practice is celebrating something today or soon, would you care to share?

Many of us used to have smaller groups on another site to celebrate things together or hold rememberances, and perhaps tildes being a together kind of community can celebrate and learn together instead of segregating into silos.

Some suggestions:

• today's date please
• what cultures and groups celebrate or commemorate this day or period?
• what is the celebration's origins and purpose?
• how does one celebrate?
• how has it changed over the years or stayed the same?
• is it reoccurring and on what calendar system?

Looking forward to learning more from other traditions and groups!

Long time Phish phan here, first show was Oswego 1999(got burned on tickets for New Haven Coliseum tickets the previous fall).

A couple of my favorite shows are 3/22/1993, 3/13/1992, 8/17/1992, 9/30/2000, 2/28/2003, 6/19/2004, 12/31/2010, 1/1/2011, and 7/23/2022

What are your favorite shows?

Hello Tildes geocachers! Found any good caches lately? Going in any good trips? Going to the Greater Bay Area Mega at the end of the month? I would love to know, and meet you online! I’d love to learn more about any interesting caches you’ve found lately and maybe we can discuss puzzles and challenges here.

Let's share our favourite mono fonts and maybe we can find some new favourites. I used to use whatever was inbuilt with Visual Studio and JetBrains' IDEs, but since JetBrains released their JetBrains Mono, I've started using it everywhere. I override the monospace font on every website with it. Never was a huge fan of Fira Code, Consolas, or the other popular ones. Personal taste. But somethings about JB Mono just speaks to me!

Are you a ligatures person? Personally, I love them :)

Disclaimer: This is just an observation of changing dynamics on Tildes! I don't mean to suggest any sort of way that Tildes should or shouldn't be.

I've noticed over the past few days that the Tildes front page has become filled with Ask posts. My best guess as to why is that these posts are the easiest to create and respond to? They're an easy way to spark discussion, generating lots of bumps back to the front page.

Now, I love seeing folks connect over all these niche topics and experiences. It feels like folks here are finding their people after losing the tight knit communities they had on Reddit, and that's lovely! In fact, it almost feels like these niche ask posts are acting as an impromptu replacement for the niche groups that Tildes currently lacks.

But, one consequence of this is that link posts get quickly pushed off the front page. I had noticed that link posts often struggled to generate discussion, even before the influx of new users. Longread articles and video essays take time to digest, and time to formulate opinions on. But now, I think this effect is compounded by the popularity of Ask threads, with fewer eyes dedicated to these links after they've left the front page.

Some closing questions:

• Have other users noticed this? How do you feel about this shift?
• Is there any merit to having a group dedicated to ask posts? Sort of like /r/AskReddit, but for Tildes? (That way, the posts can be easily filtered if a user wants to only see link posts.) EDIT: Filtering is possible already by filtering out the 'self post' tag, as suggested by @streblo.
• Should the visibility of link posts and ask posts on the front page be artificially balanced in some way?

It's pretty clear that those times are over, but I'm sure many of us remember the heydays of VC funded tech extravagance. These are the ones that come to my mind, hoping to hear others experience.

• At one point, uberpool was cheaper than the cost of public transport in the city.
• No sales tax on Amazon!
• So many promotions and code to get you to join in on their platform. This was also before they try to get you to subscribe to their monthly plans.

I am mostly a TTRPG player, but lately I have been becoming a bit curious on wargaming.

I usually play TTRPGs because it allows a lot more freedom when compared to video games. However, I can't really see that much in wargaming that you can't get in video games. Is the appeal primarily a social one?

I am not bashing wargaming or saying that it's a bad hobby. I am just curious as to what the main draw is.
Thank you for any answers :)

I found myself wishing the website had a sticky navbar on desktop, so I made a Tampermonkey script to do just that. Sharing this in case anyone else was looking for something similar.

To use, just open this link with Tampermonkey installed, and you should be prompted to install it.

I joined Tildes a couple of days ago, and I'm absolutely loving the interface and community.

In the last few days of using Tildes, I noticed a particular problem that was mildly annoying; if you have the "Collapse old comments when I return to a topic" setting on, and you click on a link that is supposed to lead to a comment in a topic you have already visited, it won't jump to that comment.

Searching around, I found a post about it from a day ago, in which long-time users have mentioned that it's been a known problem for a while now. In those comments, someone mentioned permalinks as a solution, but it appears that's still in the works.

For now, I've made a quick userscript that will address this issue (and adds some slight related functionality). It hasn't been thoroughly tested yet, so if any issues occur, please let me know. This userscript is designed to be used with Tampermonkey (a privacy-friendly alternate that should work is ViolentMonkey), which is available in all popular desktop browsers. Installation instructions for Tampermonkey are available on their site (it's installed like any other extension).

To install the script, you can head to this GitHub Gist which contains the code (click "Raw" to open the TamperMonkey install prompt), or you can copy and paste the code from the following dropdown block into a "New script" on the TamperMonkey dashboard. The dropdown is not guaranteed to contain the latest version.

The 24 hours of Le Mans is about 6 hours in! Anyone watching? Thoughts?

Besides the hour-long safety car during the rain, it's been a lot of fun so far. It's my first year watching after getting into F1 and Indycar in the past few years and I'm having a blast.

Hey everyone!

I love a good horror/thriller type movie and tend to binge on them every few months. I am however behind on releases over the last year or so :<

I'd love to get some recommendations from the wider community to add to my list of must sees!

Thank you in advance!!

It feels like in the last few years so many companies are becoming incredibly greedy in a chance to try and raise profits and please the shareholders, companies hoping that people will comply as they have no choice and give away more of their money to allow these companies to make record levels of profits.

It seems like people are getting less and less and what they have left the companies just want more and more from everyone. I'm not referencing any specific company here but I have seen these trends in the last couple of years get a lot worse.

Customer Impact

• Raising prices there is some valid reasons to raise prices, but sometimes prices are raised just as a way to make more money quickly.
• Quality reduction it feels like companies are asking more money for less quality goods more than ever.
• Excessive manipulative marketing especially on social media and other playes which can misleed people.
• Data explotation companies mis-using peoples data just so they can make some quick money.

Employee Impact

• Wage stagnation Despite the soaring profits many companies refusing to increase wages, leading to financial insecurity.
• Unfair labor practices Companies expecting more from their employees for less money basically.
• Job insecurity replacing workers with automation and outsourcing to cut costs.
• Mental health high pressure enviroments to force profit-driven companies causing record levels of mental health issues.

Society and Enviromental Impact

• Polluting Companies prioritising profits over the enviroment leading to pollution, waste etc
• Economic Inequality Coporate greed leading to income disparities, undermining social coheison.
• Unfair influence on policy Companies using their power and wealth to influence policy making

My question is, when is enough is enough? At what stage should something be done? Anything? to stop corporate greed from runing society?

So I got a 1.20m, 30kg punching bag, and hung it on the upper floor. I don't have boxing gloves yet but my friend suggested I just use cloth bandages on my hands. I'm looking for a boxing gym near me. I'm open to any striking art but I've done taekwondo before and I'd really like to concentrate on boxing now. I can throw basic punches. I've been watching some videos on boxing basics and I think it's awesome. Anything I could start working on for myself?

I'm already confident in self-defense. I don't have any specific reason to do it other than boxing looks fun. It's something I've been meaning to get into for years.

I'm not in shape at all.

Tips are welcome!

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?

Any fans of this series over here? I was planning a series reread before book 5 comes out. It was going to be hosted on the bobiverse subreddit, but... well, ya know.

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.
