Yesterday, for the first time, I got google search results that were entirely useless. I don't remember what I searched, but it was a relatively simple question and I was kind of in a hurry. The only results I got were video thumbnails and sponsored products... Also presented as thumbnails. Barely any text anywhere to tell me what the thumbnails were supposed to be. They even removed the choices across the top so I couldn't select "all".
It's been getting worse for years, but that was the last straw for me. I don't want to search the web on "large thumbnails", I want "detail view". Sometimes I'm searching for a product, but mostly I need information in the form of text written by a real human. If a search engine can't give me that, then it's not useful anymore.
Really frustrating. I guess I better get around to using duckduckgo everywhere.

Frisbee golf. It's cheap, fun but challenging, and outdoors. Worst case scenario, you go on a long walk and bump into some interesting people. If you're in a medium sized city or larger, there is probably a course and league near you.
The culture is generally very polite and fun to be around. Lots of harmless stoners and 30yo bearded people with beers in hand. In the south there is starting to be some influence from megachurches using it as an enticement, so I'm not sure if it's "cleaned up" a little more down there.

Thanks for the suggestion. I tried spacerpg4 but it hasn't held my attention as much as I hoped.
I did find an android port of star control 2, and that is some good stuff. Really scratched the 90 gaming itch too.

They run on 1V per octave control voltage. Lots of keyboards can output that natively, the arturia keystep is what I have because it has some sequencing capabilities as well.
There are tons of circuits out there for midi to CV conversion. Arduino is harder than you'd expect because it can't output straight analog so you need to interface with a DAC or filter of some kind. Temperature compensation is also pretty important. Obviously not insurmountable problems, so there are lots of DIY designs of varying quality. Here's the second one I found on a search: https://github.com/elkayem/midi2cv
You can have a really good time with the sound lab mini synth 2 and a sequencer or keyboard. It has 2 voices so you can animate a drone and sequence/play over the top. Or use it to drive spectrally rich audio into a bigger system for processing with mutable modules or whatever. Sky's the limit :)
If you want a relatively straightforward, but still really cool project, the echo rockit is where it's at. Makes a great effect and is still a fun stand alone noisebox.

No shade on "how it's made", it's one of my favorite shows. But I think a LLM could probably write most of the narration. They primarily describe what is happening on screen. You might have to train one special to have information on industrial and manufacturing processes.

You ever used a Deutsch Weatherpak connector? We use them on mobile equipment. They have a spring loaded face seal then a solid lever lock that is plastic but substantial enough that it's usable. They're pretty good wire to wire connectors. I'll take anything with a twist lock though, BNC etc.

I don't think it's totally fair to call it ugly either. It's a masterpiece of efficiency. The ASCII looks messy to some people, but after a while you just see right through it; purple Y = catlobe gtfo etc. Plus the upside is that it's extremely clear at a glance what is going on because you don't have complicated sprites everywhere. And the handmade vaults that get rolled into the procgen are often really nice looking and give the world a lot of character.

Totally get it. My SD card got corrupted in a power outage almost a year ago and I never got around to reflashing it. To many other irons in the fire.
I must say, it was an impressively reliable setup, uptime was effectively limited by power outages. Their image is basically Raspbian which is basically debian, but I was still impressed that the service was so stable.

The only problem there is that the count also determines how federal money is distributed. Undocumented/illegal immigrants still use interstates and water mains and disaster money and national parks and federal buildings. Unless we want funding cut, we still have to count them.

Oh shit, I never even thought about that. It's another level of insidious. 1. Be republican 2. Get a huge prison in your district "for the jobs", 3. Get more positions guaranteed to be republican, since the voters in your district still are. Would work for a democrat too, they don't care about criminal justice reform either :(
Might work slightly better for republicans because they can work the identity politics angle more easily.

If you have a little technical skill, you can set up your own raspberry pi ads-b receiver really easily. Just need the raspi, and SDR dongle, and an antenna. Floghtaware provides a flash image for the OS. If you feed them data, you get a free premium subscription. I used to use it to get alerts when the state patrol speed trap aircraft were taking off so I knew not to speed on a long interstate commute.

Do you know of anything like this for the switch? I'm a late comer to handhelds since I developed some shoulder problems and can't really PC game anymore.
I used to love a game called transcendence back when it was a free alpha. Top down, open world, semi-roguelike, big focus on combat with satisfying 2d physics and lots of ship customization. Less focus on trading and world interaction stuff.
I've looked at a couple you guys mentioned, but I'm really trying to find something that'll scratch that 2d space combat itch on a handheld.

There are a few kinds of steam!
Wet (unsaturated) steam: this is probably what's coming out of the instant pot. It's gasified water mixed with tiny particles of liquid water. Industrial processes do not want wet steam in their systems. They have machinery to separate the liquid out. If that liquid water settles out inside a pipe and blocks it, it'll go shooting down the pipe like a bullet and cause damage to whatever is at the end of the line. If the droplets get into turbomachinery, they'll tear up the turbines. Adding additional heat will not increase the temperature, but will get consumed by the phase change to evaporate the remaining water and change the wet steam into...
Dry (saturated) steam: this is precisely the point when all the water has been evaporated. If you remove heat, it will start to condense without changing temperature. If you add additional heat, it will increase the temperature of the steam, because there is no water left to evaporate. This is useful because changing phase between liquid and gas consumes/yields a ton of energy, and that happens at a constant temperature. So if you need to transfer heat from one place to another, then saturated steam is what you want. Adding heat to saturated steam gets you...
Superheated steam: at this point you can conceptualize water as a gas. Intuitively, it works just like air or nitrogen or whatever. Pressure/temp relationships act like you'd expect from your everyday experience, because you're far enough above the gas-liquid phase change temperature that you don't have to worry about condensation getting into your equipment. If you want to use steam as a working fluid in turbomachinery or something, then you want superheated steam.
All three can hurt you badly, but inadvertent contact with superheated steam will fuck you up or cause irreversible death.

Yeah, but then they go and open all the windows to "change the air" no matter the weather.
I used to work with a bunch of Germans in the US. I came in to the office one time at about 4:30am in February. One of the guys had all the windows open when the outdoor temperature was something like -20F.
Like Moritz, I think that avoiding the draft is more important than changing the air at that point. 🙄
I also had an old manufacturing guy tell me that drinking cold water in the summer would kill you because of the shock to your system.

Dark souls 1 or the remaster is still worth playing. The map design is once-in-a-lifetime good. There is a pretty hefty penalty like in other souls games, but it's just getting hollowed and losing some souls. DS3 is also good, maybe a more refined version of 1, but I personally don't think the world is as cohesive with the loading screens.
The trick is to just get used to being hollowed all the time and spending souls asap when you get them. You don't lose gear when you die, and gear is pretty important. The real progress comes from learning how to deal with each enemy though, and that comes from dying. I guess it sort of boils down to "git gud", even though that wasn't what I was trying to say here lol.

To add a little: when a thing fails in compression (submarine), it's usually unpredictable and catastrophic. When it fails in tension (spaceship), it starts slow and fails in a predictable way.
Tension is also much easier to calculate when you're designing structures. Engineers will often go out of their way to make sure that tensile failure is the controlling failure mode, just to make sure that we don't have to fuck with compression.
nickajeglin 1 year ago • 100%
I never thought about it this way, but I think you're right. I'm an engineer, and we go out of our way to avoid designing things that need to resist compression. Tension is much easier to calculate and things fail in a more consistent and predictable way. When things fail from compression, it's usually unpredictable and catastrophic.
You compensate for that by making it as symmetrical as possible to balance forces and increasing safety factors to stay very far away from a runaway failure situation.
The designers of this sub were crowing about some kind of "active monitoring" system to see if the hull was in danger in real time. My take on that is they cheaped out on construction and slapped some strain gages (detect micro-bending or stretching) on it to make sure they didn't get too close to failure from going too deep. But if there was a material or construction failure, it would just pop like a bubble before the strain gages could tell them anything was wrong.
But anyways, a spaceship is mostly under tension, but a submarine is under compression. So I think you pretty much nailed it there.

As long as their CO2 absorbers hold out, hypoxia is a pretty easy way to go. Pretty much any other option sound real bad though.
Somehow this building is isolated against the sky even though it's in a really packed part of town. The texture of the building face and the triangle of light over the N caught my attention, so I pulled over to take a photo. This one was surprisingly easy to print. I stabilized the side of the camera against a light pole, and I think that contributed to the sharpness and detail as compared to a lot of the other shots I've taken. There's something about these little corner stores that I find comforting, especially when it's so late at night that I'm the only one around. I hope you like it. > Edit: the title shouldn't be a link. It doesn't go anywhere. I was just duplicating the peculiar way the name of the business is painted on the front of the building :/
![](https://lemmy.one/pictrs/image/40762f1e-0b5f-464a-b7df-14219f2de87b.jpeg) I took this at the zoo. The sea lion was playing with the kids and they were reaching and jumping begging it for attention. Just after I took this picture, the sea lion playfully snapped at the kids through the plexiglass, and they all happily screamed. I hope the picture makes you smile. My grandpa gave me an olympus om-2n, and a family friend was offloading his entire darkroom, so I ended up with all the stuff for free. Since then I've been blundering my way along, and after a year or so I feel like I'm starting to get some control. I'm not normally an artistic person, but I really enjoy how methodical you need to be with the analog process. If you enjoy this, I will post a few more. I had a manic episode a couple months ago, and produced some pictures that I think are ok.
This site is a huge collection of simulation applets for analog circuit, filters, acoustics, general harmonic stuff, quantum mechanics, thermodynamics, linear algebra, and so on. The analog circuit simulator in particular is very feature rich. I have used it to design some synth circuits in lieu of/addition to breadboarding. Also try the acoustics ones, especially the ripple tank. The examples drop down has a bunch of cool setups like speaker designs, mirrors, lenses, mechanical filters(!), and can even simulate temperature (impedance) gradients.
This one is Ray Wilson's DIY synthesizer website. I first saw him on [youtube](https://youtu.be/0NDlRXwpS1w?list=UUp6OK4J97aPWccFpUgKj_Mg&t=1167), screwing around with an [echo rockit](http://musicfromouterspace.com/index.php?MAINTAB=SYNTHDIY&VPW=1910&VPH=797) noise box. I was hypnotized. I found his site and was hooked. I spent the next couple years making synthesizer modules at a manic pace. The magical thing about Ray's site is is his teaching style. He gives the circuit schematics, but also explanations of how/why they work in language that is pretty easy to understand. He really approaches electronics from a practical standpoint rather than what you'd get in an intro class somewhere. This website was my introduction to electronics, and it can get you far when it comes to understanding analog design and signal processing. You can really get a feel for Ray's personality from his writing on the site. He died in 2016, and I weirdly get a little choked up when I look at that echo rockit page. His website was a right-time-right-place thing for me, and it helped change the trajectory of my life in a very real way. Anyways. Check out [Music From Outer Space](http://musicfromouterspace.com/index.php?MAINTAB=SYNTHDIY&PROJARG=ELECTRONICS/analogsynth101.html&VPW=1910&VPH=756), and like Ray would say, Good learning...
This is the website of Gene Slover (now deceased). He was a firecontrolman in the navy back in the day. Now I don't care about the navy, nor do I really care about Gene. What I do care about is *mechanical computers.* Firecontrolman in this context is the dude who operated the Mk 1 fire control computer on navy ships. Gene's website is significant to me because it has a massive amount of information on the design and operation of that computer. It's wild to me that information this detailed is out there, cataloged by someone who actually operated the system. Here's a short writeup that I posted elsewhere to explain why I think the computer is so cool: > The mark 1 fire control computer is an entirely mechanical computer that reads in the speed of the ship in water, the wind direction and speed, the pitch and roll from waves, the ballistic characteristics of the guns all the way down to how worn in the barrels were, and so on. Then a gun director feeds it the bearing, elevation, and distance to a target, and it does that rapidly so the computer can establish a vector. > So at one end you have a guy with a telescope/rangefinder that he points at the incoming plane, and that's all mechanically connected through a calculating machine that aims the guns the right direction, sets the fuzes to the right distance, and applies "corrections for gravity, relative wind, the magnus effect of the spinning projectile, and parallax" so that the shells explore right on a plane that zooming by. > They did all that with levers, cams, gears, mechanical integrators, etc. And they made that super complex machine reliable enough that it was used in a loss-of-life application. That's some pretty badass engineering imo >Here is a much more in depth page about it than the Wikipedia entry: https://eugeneleeslover.com/USNAVY/CHAPTER-25-C.html > And his page has a flow diagram that shows all of the inputs, intermediate quantities and outputs of the thing. I wish I could actually read them :( https://eugeneleeslover.com/USN-GUNS-AND-RANGE-TABLES/FLOW-SCHEMATIC-COMPUTER-MK-1MOD-7.html >I mean check this shit out. They had an adjustable integration step size so that you could manually adjust to balance between firing solution speed and accuracy: The rate control system of Computer Mark 1A includes sensitivity units which control the time required by the computer to reduce errors in generated rates to the point where the corrected rates are sufficiently accurate to compute adequate gun orders. Sensitivity may be thought of as the speed with which the errors are corrected by the rate control mechanism. If the errors are corrected within a relatively short time interval, the sensitivity is considered to be high, and if the errors are corrected within a relatively long time interval, the sensitivity is considered to be low. Blows my mind.
This section of the Project Rho site is one that I have actually used for real projects in the past. The section gives guidelines for creating [nomograms](https://en.wikipedia.org/wiki/Nomogram), or alignment charts. Nomograms are graphical representations of a math equation. For a basic 3 variable equation, given 2 of the variables, you simply lay a straight edge across the chart to read the answer from the 3rd scale. The specific page I linked is a cheatsheet of "standard forms". If you can manipulate your equation into one of these forms, then making it into a nomogram is trivial. This page is one of very few resources online that will take you step by step through building a nomogram. The intended purpose of the page is to be a resource for board game designers, but I have found it useful in creating time/distance/speed nomograms, various engineering calculations, and calculators for film photography and darkroom printing. Even if you aren't a math nerd, I hope you find the idea of a graphical representation of an equation as fascinating as I do. It doesn't tell you the answer to 1 question, it tells you the answer to *all* the questions that an equation can answer simultaneously.
I found this buried in my garden. It’s steel, with some flecks of galvanization still visible here and there. Definitely stamped from sheet stock originally, the ring is welded, and it’s especially interesting to me that the right “foot” of the little “table” cutout is narrower than the left one, as if it’s keyed to connect to something in a single direction. Ideas so far: * livestock tag (we live near ooold stockyards) * cremains tag (spooky) * key fob/id (but why the welded ring?) Does anyone know what it really is?
I have a large terrarium where I grow various types of moss. I keep springtails in there to handle any mold that pops up, but some creature (fungus gnat larvae?) was killing off the springtails. So I captured a jumping spider, thinking it would gobble up the fruit flies/larvae. The fungus gnats have disappeared, so it seems like the spider might have done the job, but now I'm worried about it getting hungry. I gave it a mayfly a couple days ago, and that evening it was sitting in the corner of the terrarium like a toddler with a juice box, so it obviously likes those. Are there any specific things that are good to feed it, or can I give it anything that I catch that isn't predatory? For example, would a "regular" sized moth be dangerous? It'd be like 2-3x the size of the spider.
It seems like comment text is always much bigger than the rest of the text in the app. If I change the text size from 16 to 12 in the settings, then most text gets very small, but the comment text is still around 14. This feels backwards and makes it sort of hard to read, I'd much rather see all the other text at 16 and comments at about 14. Is there a way to set that up?
It's my favorite plant, in the next 2 or 3 years, the entire side of my house by these hostas will be filled with it, and I'm super excited. I've noticed there are 2 cultivars available in my area. The more diffuse kind in this picture, and a much more compact and shorter version. The one in the pic is incredibly cold hardy, it stays green through zone 5 winters. The shorter version is not hardy, but looks incredible as it drapes over the edge of a pot. Does anyone else have a big plot of creeping thyme, or any other low ground cover they love?
