Superconductors is this magical new supposable discovery solve all of capitalism problems and head towards eco-capitalism?

HA!

It might reduce eco waste but how many years will it take to make it factory assemble ready and will they use it?

Superconductors still have a maximum current they can handle before they heat up and lose superconductivity. Most can do 20 kA/cm^2, so if you want to move say 2 GW through a 1 cm^2 cable, it would still have to be at 100 kV.

Is the entire gamedev community cucked? Nearly impossible finding a recent github project without some 'permissive' but non-copyleft license. Why would anyone as a reaction try to clone a game they feel should belong to the community while giving other usurpers the chance to turn it into a botched IP?

>barely graduated highschool, but expert in Constitutional law

This complaint makes no sense. The constitution has been written to be accessible to 18 century retards. How many of them do you think had a highschool diploma? And that's a liberal document anyway. Laws in socialist States should also be written as plainly to avoid making stupid class distinctions based on educational achievement like these. And the lawyers get shot first so it can't be any other way.

they develop primarily on windows, would rather beg Microsoft for dev tools than use free ones, use stuff like perforce (whatever the fuck) instead of git, would rather "license" trash engines then modify for their own use than modify an existing open source one, basically putting in effort just to keep it closed, no other reason.
gamedevs are cucked beyond belief and will willingly go lower and "gamers" are even worse where they will pay these gamedevs 2 years in advance through "pre-orders" for whatever closed, often not even functional on launch garbage they will release.
the whole game industry is possibly the most nightmarish example of consumerism that is worse than anyone could have even imagined. people pay to rent (not even own) non-existent products many years in advance.

I was shooting heroin and reading “The Fountainhead” in the front seat of my privately owned police cruiser when a call came in. I put a quarter in the radio to activate it. It was the chief.
“Bad news, detective. We got a situation.”
“What? Is the mayor trying to ban trans fats again?”
“Worse. Somebody just stole four hundred and forty-seven million dollars’ worth of bitcoins.”
The heroin needle practically fell out of my arm. “What kind of monster would do something like that? Bitcoins are the ultimate currency: virtual, anonymous, stateless. They represent true economic freedom, not subject to arbitrary manipulation by any government. Do we have any leads?”
“Not yet. But mark my words: we’re going to figure out who did this and we’re going to take them down … provided someone pays us a fair market rate to do so.”
“Easy, chief,” I said. “Any rate the market offers is, by definition, fair.”
He laughed. “That’s why you’re the best I got, Lisowski. Now you get out there and find those bitcoins.”
“Don’t worry,” I said. “I’m on it.”
I put a quarter in the siren. Ten minutes later, I was on the scene. It was a normal office building, strangled on all sides by public sidewalks. I hopped over them and went inside.
“Home Depot™ Presents the Police!®” I said, flashing my badge and my gun and a small picture of Ron Paul. “Nobody move unless you want to!” They didn’t.
“Now, which one of you punks is going to pay me to investigate this crime?” No one spoke up.
“Come on,” I said. “Don’t you all understand that the protection of private property is the foundation of all personal liberty?”
It didn’t seem like they did.

Brought to you by Adobe, BBC, Intel, Microsoft, Sony to keep "online misinformation" (AI-generated content) in check with what amounts to DRM for digital media. It's pretty easy to get spooked by all of this.
Now to be fair, it's an open standard, so maybe the comparison to DRM isn't entirely accurate. They also claim it's opt-in, but I doubt it will stay that way. As the video >>20955 mentioned, Steam is already cracking down on games with AI-generated content so requiring C2PA seems like a logical next step for them, as with other web services.

Here's the technical specification by the way (perhaps someone can upload it): https://c2pa.org/specifications/specifications/1.3/specs/_attachments/C2PA_Specification.pdf
Here are a few key parts from the introduction (chapter 1):
>C2PA specifications SHOULD NOT provide value judgments about whether a given set of provenance data is 'good' or 'bad,' merely whether the assertions included within can be validated as associated with the underlying asset, correctly formed, and free from tampering.
>The identity of a signatory is not necessarily a human actor, and the identity presented may be a pseudonym, completely anonymous, or pertain to a service or trusted hardware device with its own identity, including an application running inside such a service or trusted hardware.
>The creators and publishers of the media assets always have control over whether provenance data is included as well as what specific pieces of data are included.
Another thing to take note of is chapter 18 which lays out the team's assessment of the "Threats and Security Considerations" and "Harms, Misuse, and Abuse". They basically say they will address these concerns sometime in the future. Pretty unsatisfactory in my opinion.

If you click on the info icon on an image on this webpage, you’ll be able to see who took a photo, where, when, and with which device. You can see the tools they’ve used in Photoshop to edit the image and, by clicking the “View more” button, you’ll even be able to compare versions. This adds a layer of transparency and veracity to images that has never before been possible, so that any viewer of content on a news article or social media post can evaluate what they’re seeing and decide whether or not to trust it.

The problem is what happens if there was no edits made in the software that makes this meta data as all edits were made prior and imported in.

Fucking KNEEL. You will die but C will live. C wont die out because of embedded systems. So long as there is electricity, C will be forever. C is used in kernels. I like to see fools who think C will die. C prioritizes the purity of atomic control, raw power, and a small and manageable feature set because that's what the rest of the computing world needs as a foundation. A feature not provided can't be flawed or slow - the fewer features are crammed into C itself, the less opportunity there is for bugs to creep in beneath the very feet of every OS and many interpreted languages at the same time. Python is the worst language to start with because it promotes bad practices and doesn't really teach you anything not to mention dynamic types make it hard to understand certain concepts like how data is actually represented and it creates this illusion that basically lie to people as to whats actually happening. having that much disconnect from processors that do very simple things to accomplish a specific task and over-engineering solutions because it conforms to language syntax is just stupid. there is no better starting point than C. C syntax is explicit and clear and actually lets you do exactly what you want to accomplish conforming to the actual hardware and not some made up language syntax. its why c will never truly be replaced. The current languages that are shilled in shillicon valley are all terrible. JavaShit is a complete disaster and we are stuck with it and that's the reason we have tons of dependencies and libraries with very sketchy glue code. OOP is also bad as it has a lot of hidden allocations that happen with constructors and make compile times more complex and harder to optimize or debug compared to simple functional direct code without a million rules that you have to follow giving you no real freedom to design software. There are reasons to redesign and make custom engines for handling specific tasks. Most languages cant exist without C, as their runtimes are all basically C, and it's the language that runs other languages and provides the abstractions people use. When you no longer have to think about hardware or what your code is doing that leads to ruin and slow sub-optimal code and libraries and dependencies. Python is ugly and hard to read. you have absolutely no idea what most of those libraries are actually doing and you lose sight completely of programming and live outside of reality.

I think this has to do with the requirement of a turing machine to process a theoretically infinite input "tape" conflicting with C's mandated use of fixnum pointers. You could get around this limitation by writing custom allocation and dereferencing routines, that use arbitrary length pointers and may grow a theoretically infinite page table by manually swapping to disk.

Wouldn't that mean that it is then theoretically possible to do robust static analysis on programs for things like security vulnerabilities, segfaults, shit like that?

 No.20948

>>20947
Bound checking of arrays is already a staple of linters and has a gcc switch i believe. C programs are made unpredictable the most by the ambiguouity of API definitions.

Character strings may either be null terminated or passed with their length (functions handling both exist), yet there is nothing stopping the caller from violating both. While the compiler can hook into the allocator calls to perform static bound checks or warn about an index range, the programmer may misplace or inadvertently copy a null terminator and miscalculate a string length smaller than the data.
When passing string arguments to external functions, static analysis is simply impossible. The newer standards define some semantics whereby compiler can detect some of the possible errors though: https://gustedt.wordpress.com/2023/06/10/enforced-bounds-checking-for-frozen-function-interfaces/

I thought the biggest issue is aliasing.

 No.20950

>>20949
Writing to an aliased pointers isn't strictly required for use of the language and can be forbidden with restrict from C99 or __restrict implemented by most of the C89 compilers.

Compilers can detect dangling pointers in function scope just as well as uninitialized variables. The state necessary for this is lost when pointers are passed to other non-inlined functions as arbitrary fixnums.
If however C pointers were a datatype with shared state that must point to a valid memory location, dangling pointers could at least be diagnosed with runtime checks. Some testing frameworks modify the allocator to track all current allocations.

In any case the semantics for passing standard C types require a lot of faith from both the caller and the subroutine, which i see as the primary defect at work.

Anyone watch those shows about prison inventions? I wonder what the most sophisticated onss would be. My three biggest questions would be

1.) A gun
2.) A computer
3.) Bombs
4.) A canera
5.) A jet pack

P much all improvised stuff you see in prisons are all essentially the same thing: pointed weapons. If you went to prison and you were squaring up with some hardened convicts who are all armed with shanks, you'd need to upgrade in technology to fairly face them head-on since the no. #1 rule in a fight is there are no rules whatsoever. For a gun I was thinking of a Gauss rifle (similar to the Arc Flash GR-1 Anvil which has the same amount of muzzle velocity as a .22lr (note that most "Gauss guns" you see on YouTube are harmless toys). They shoot small magnetic projectiles and are quite bulky in size. I was thinking you could propbably make one (including the capacitors) out of car parts, among other things like wires and stuff. Because I know there are automobile jobs available in prisons in the US. These guns require no powder propellant.

Second one is computers. I heard one story of an inmate in ohio that made computers and connected them through the ceiling straight into the WiFi network out of pre-made computer parts. Obviously not everybody has access to salvaged and repurposed computer (esp not ones that can easily be smuggled) so my idea would be to make a PDA out of the Electronic Control Units to a car (which connects to the Controller Area Network). But then again I'm no expert in engineering, but I do know that a lot of people in prison do, since all they have is time on their hands whereas most people are preoccupied.

As for bombs, I would think that whoever is in the woodshop could make a Roman-style Ballista + tin cans + airbag inflators from cars, again, from a prison job, since the older ones come in capsules that have sodium azide in them - which is a shock sensitive primary explosive (sometimes mixed with potassium nitrate and silicon dioxide to reduce harmful byproducts), whereas the newer ones rely on a mixture between Guanidine Nitrate w/ Copper Nitrate as the oxidizer. There was one Japanese company that sold ammonipum nitrate airbag inflators that ceased production due to lawsuits anx recalls that still might be on the streets even now. And aside from that, some newer cars use gases as some experimental thing (I think helium or argon-helium mix). But azide and ammonium nitrate-based ePost too long. Click here to view the full text.

>Image-to-image translation is a class of vision and graphics problems where the goal is to learn the mapping between an input image and an output image using a training set of aligned image pairs. However, for many tasks, paired training data will not be available. We present an approach for learning to translate an image from a source domain X to a target domain Y in the absence of paired examples. Our goal is to learn a mapping G: X → Y, such that the distribution of images from G(X) is indistinguishable from the distribution Y using an adversarial loss. Because this mapping is highly under-constrained, we couple it with an inverse mapping F: Y → X and introduce a cycle consistency loss to push F(G(X)) ≈ X (and vice versa). Qualitative results are presented on several tasks where paired training data does not exist, including collection style transfer, object transfiguration, season transfer, photo enhancement, etc. Quantitative comparisons against several prior methods demonstrate the superiority of our approach.

All of their phones are overpriced fucking garbage and always have been. The products that aren’t phones can still be considered as useful as literal e waste and only exist so petit bourgeoisie can float about their Shri no one cares about in public like the rats they’re, no one gives a shit about AirPods watches fucking whatever they hell they call computer stands in the slightest and they improve nothing about electronic hardware. All of their products wear out in a year at best and god forbid you don’t have protection for any smartphone/Mac you have for those things because they will break instantaneously(reminder these rats will prohibit you from being allowed to fix your phone from private repairmen) and all of apples products might as well require you to file out your entire life’s story worth of info to use or download because that company couldn’t give less of a shit about how much info they collect on their customers and exist as a vassale of the American government. I wish it was just apple that was a noninnovative vapourware tech corporation but unfortunately the entire western big tech industry thrives on hype and stolen ideas and hasn’t pumped out anything innovative in over 60 years except for the might as well be dead corporations that are IBM and Intel that only make me moderately dislike capitalism less because they actually have humanity something that wasn’t complete and total utter fucking nonsense

I’ve held off on getting a MacBook for years now, but the time feels like it’s edging closer and closer. For the past 20 years I’ve been gaming on windows, but recently I got lazy and have been using a used ps4. My ‘gaming’ Lenovo is now 5 years old. It’s beaten and battered with shattered plastic parts and a huge cracked screen. It’s become a burden with how large it is, how ugly it is, and how shit it’s battery life is. I don’t think it’s ever lasted longer than an hour unplugged. It can’t run modern games like it used to. Windows now periodically gives me advertisements as it freezes and makes my life a living hell. I am not the computer guy I was back in 09’. I feel like getting a Mac is giving up and moving on. I don’t want to have to buy new usb-c gear. I don’t want to have to adjust to mac settings. But I know it’ll probably be easier for me and my work. The work will get done.

I came across unstructured link farms, fake filesharing sites and autogenerated reviews before, but this type of site seems unique to me if only because of the moderate effort needed to set it up.
