How close are we technologically to creating 3d projectable holograms like in science fiction?

Is such a thing even possible by the laws of physics?

Volumetric displays
you can buy the first ones now, but they only do photo. perhaps in the near future it will do motion and your tv will be volumetric making it feel more like a window then a flat screen.


not a real hologram (like tupac and MJ),it's a 2D projection made on stage on an thin and transparent inclined surface that give the illusion of depth.


The full hologram with light emitting voxels (3dpixels) floating in mid air without any substrate or mirror tricks are in the extremely early proof of concept stage with extremely crude projections.

One way to do is using lasers that ionize "dots of air" to create a small plasma bubble that briefly emits visible light like a glowing point source.

Here is a more advanced one that can do some amount of tactile feed back and also sound by moving around a scan particle with acoustic energy


Lmao that looks like some shitty Chinese-made toy/decoration of some kitchy picture stored in a small packet of water that I would buy from a coffee stand for 0.99$


what about shit like the holograms from star wars


What's everyone think of this language? looks like a statically typed, compiled version of ruby?

Can it compile to binary/metal (I forgot the proper term) instead of LLVM?


Despite having its own language, LLVM is a compiler infrastructure first and foremost.
The manpage of crystal also says it to compile to native code by default:

Kinda nice but I don't think you can use existing Ruby libs because Crystal's stdlib is slightly different.


True, but that turned out to be a major problem when the original dev stepped down from the project. Look up old issues in the github repo around that time. People mass-complained about the language choice, and it looked like the project might die very soon because nobody could fix anything. Invidious is the kind of thing that needs incessant changes because it's playing cat and mouse with Youtube.

Fortunately the current devs are extremely active and will also test and merge your patches very quickly, so it wasn't that fatal.

Most businesses are never ever innovative and rarely ever produce anything to consumers that isn’t overpriced garbage but they might’ve done something different. This is genuinely one of the only companies I’ve seen that
>actually innovated without government aid
>actually produced a finished product
>actually treated its workers decently
>expanded in size naturally through genuine labour
What was different about IBM compared to other companies and why the fuck didn’t succumb to the same hyper culture vapourware faggotry that is the rest of the American big tech industry?

>Most businesses are never ever innovative
I agree with you here but provide some examples
>actually innovated without government aid
>actually produced a finished product
>actually treated its workers decently
Proofs and examples for all of these claims.
>expanded in size naturally through genuine labour
What does genuine labour mean and how does it differ from the expansion of other capitalist enterprises?
>succumb to the same hyper culture vapourware faggotry that is the rest of the American big tech industry?
Why are you only comparing IBM to the tech industry? IBM has existed for over a century, how do they compare to traditional industries like automobiles, steel, aerospace, chemical? All of these industries made "innovations" over the past 100 years, I don't think IBM is particularly remarkable compared with the likes of Ford or Boeing or Dupont.


they were heavily involve in categorizing jew and communist in Europe that list was later use by the Nazi


Its government funded militarized computer innovations kept it afloat.


They were a monopoly, so they could fund R&D and good salaries. They knew that if they didn't fund R&D they would lose their monopoly status.

I don't really care for tv, but I have been thinking about setting up a satellite dish but i have absolutely no idea where to start.

What can i get with a satellite dish? Does it get too expensive anyway?


You might be able to hook a satellite dish up to an SDR and spy on various things with it.


if its cheap itll wear out in a few months, what devices do you even plan on hooking up to that thing OP? also uyghur


look up FTA receivers
or use it as an antenna for your choice of RF application

Does /tech/ participate in the Fediverse? Seems to me that this is the sort of social media we should be trying to get people into, even if social media itself is kinda trash.

I've always disliked social media, but after the news at >>>/leftypol/1066439, I've been considering getting into the Fediverse. You see, I would like the people who DO use social media (basically everyone) to be on better platforms, but I feel I cannot demand that from them if I cannot even use them myself. For instance, it would be disingenuous to ask Comrade Cockshott to start his presence in Mastodon after getting banned from fedbook if I could not be there to follow him and boost his follower stats. So..

So, /tech/, any thoughts on the Fediverse? What are some good instances and communities I could join? What are some people I should be following? What implementations are better, Pleroma, Mastodon, something else?

Also fediverse general.

>computer predicting the future
was a miniseries already


It's funny because China has been making accurate predictions of the future for deacdes and all they needed was dialectical materialism.


and yet they couldn't predict that forcing farmers to make shitty low quality steel instead of food would starve the nation. they failed to predict that their sloppy safety standards would let slip a pandemic from their sloppy chinese labs. and yet many people predicted these things before they happened without dialectricals or whatever nonsense. they failed to predict that building houses on debt nobody can afford to live in might cause some issues. oh dear well maybe one day they will actually predict something and then your comment won't seem completely out to lunch.


They already are predicting things it's just mostly "will X buy this product at this time" so they can serve the ads to you at time you're most likely going to buy it. Whether or not these systems can predict anything on a grander scale is just a bonus to them.


They want to prevent the unpredictable, but that's part of the larger goal of maintaining the status quo. The goal is not to intervene at the level of causes but at the level of effects. Big data is inherently like that, it only spits out correlations and deliberately ignores causation. Causation is too "metaphysical", we only care about raw numbers. Why does somebody want to drive a truck into a crowd? Who cares, what matters is to detect it and manage it. This is why we're also seeing a push for everything "smart" where a set of possibilities is literally pre-programmed, again to prevent the unpredictable. Ideally you won't even be able to commit any act against the system because the "interface" won't have the option, so the system can do away with managing side-effects as well because there won't be any.

This system has no projects, no dreams, no future. It doesn't want to fundamentally change anything. It might create a spectacle of incessant change, but it's all merely an incremental improvement in how to best recuperate and manage.

I believe that hardware is the most essential component of an electronic, and that as a computers task becomes increasingly convulted the type of hardware a computer needs also increases. This electrification of common tools can increase to the point where everything about a society can be maintained and controlled with a single device or a master computer. What massive steps in society must be taken to build such a contraption


decentralization is the way to go, any one central system will be vulnerable to whoever controls it or whoever hacks it or corrupts it. rather then having all the eggs in one basket: we decentralize. that seems to be the trend. the master computer is more software then hardware. it runs decentralized apps, dapps not apps. they call it the world computer: ethereum.


File: 1633536864093.png (186.89 KB, 1636x941, ClipboardImage.png)

decentralization or distribution?


your comment provokes a lot of thought but i have no answers for you. tell me more.

perhaps one issue with full distribution is that it requires all participants to have the computing power and bandwidth to run the chain. where as with nodes you don't need to personally have a computer with that level of power or that level of bandwidth to use it. however data will become cheaper, computers get more powerful. but demands on the hardware also increase.

Hey guys, scarce here. As of late I've come to realize that most desktop environments are kind of shit since they're either just bad like xfces or really bad like GNOME/KDE, and tend to be unstable, often having updates that completely change the desktop and workflow so I've started to look at more lightweight options like window managers. So far the benefits seem to outweight the negatives.
> Stable, you make your own config and it never changes unless you want it to
> No gnometroons or Scalies causing drama in your git issues

Cinnamon's been fine for me for a while now. I used GNOME 2 before GNOME 3 landed in Arch Linux. After that I was switching between Mint and Debian, now I've settled on Mint Cinnamon because I don't want to deal with extensive ricing anymore. It's easier to debloat than to build up a system from a minimal install.

For your requirements I would look into Void Linux, but it turns you into a troon accoding to /g/.


>>11942 (me)
Forgot to mention, I used i3 for a few years. It's very nice despite the hype so give that a try as well.
But for me it was ultimately just one more thing to continuously reconfigure - I've even ended up writing a library that can programmatically manipulate i3 objects over IPC. But over the years I've just grown tired of reconfiguring the basic shit, I'd rather extend an out-of-the-box functional system with my own programs.


that's where you're wrong kiddo
awesomewm is functional and perfectly usable without any ricing. In fact, I use the default config on desktop. On laptop I have done some configuration like copy pasting battery indicator code snippet into the config.


what "command line" style window manager looks the coolest and most hackery?

Just want to earn my paycheck to feed myself from something that will work for at least 4+ years and be durable in a chaotic home environment.

I heard stuff about how the new ryzen laptops are crazy good worth of money for the consumer. Don't know much about cpus wars.

Only want to be able to do my work fast on it without lagging under heavy load.

Will be using many many browser tabs, excel sheets, word documents, and pdf softwares. No games or anything. Just work.

What durable laptops would you suggest for these purposes in the $300-500 dollar range. I just want to fully utilize my purchasing power while buying this laptop because i'm kinda loaning the money from somebody else ;-;

Framework laptop, if an old thinkpad doesn't cut it for you.


Would any Thinkpad do?


Seconding this. Got a T450s years back. I'm not exactly a power user, but it was a reliable daily driver for school and personal use. IMO these magnesium body thinkpads have some of the best build quality of any laptop out there. I've traveled with it,dropped it so many times, and it's at the age where laptops start falling apart but it's still going strong without any mechanical issues.

T480 is still relatively modern and is the last model with hot-swappable batteries, upgrade-able RAM, and upgrade-able SSD. The last model with socketed CPU is the T440p, but it's an older model and has an infamously poor trackpad (which can be upgraded however).


>>11938 (me)
Wanted to correct myself and say that in addition to T440p, the W540 and W541 also have socketed CPUs. However, they're becoming memepads which has seen their prices go up considerably.

summary: Classic Thinkpads (X200->X230, T400->T430, X60/61, T60/61) are becoming less budget-friendly, especially when you factor in the cost of repair (may be necessary) and maxing out the specs for modern use. If you want something to handle modern workloads and still want maximum upgradeability, then T450/T450s -> T480/T480s are your best bet.

As for buying them, avoid big retailers like Best Buy and Amazon. Ebay is usually the best secondhand market, but you can also find plenty of gems on shopgoodwill and craigslist


I bought a refurbished T450s just this year. It's the last thinkpad model that doesn't need screen scaling (1600x900 @ 14.0in = 131 PPI). Screen scaling is still utter shit on any OS. Build quality is worse than early Lenovo / late IBM, less serviceable as well, but still better than other manufacturers. I replaced the keyboard with a Lite-on one. Chiclet keyboard but better quality and has highest key travel compared to other keyboard manufacturers.
