I've been thinking about how windows programs could be run on linux. The consensus is pretty pessimistic, but I figured I'd make a thread anyway. The goal is to painlessly run programs like VNs on linux without the need to port them or write any custom scripts for each., and instead be able to put them in a small box and have them run flawlessly.

Wine's approach seems overly complicated and unreliable. Virtualization just works. Windows virtualization is heavy as hell though. Booting up a windows vm is annoying and slow. It would be nice if you could have the reliability of virtualization, but in a way that's much faster and smaller than how it is now.

Docker supports linux containers on windows by emulating a really tiny linux distro(as far as I understand). So why couldn't the opposite be possible? There's no official, really tiny version of windows that can run win32 apps, but ReactOS's iso is only 145 MB. I looked and found practically no information comparing the reliability and ease of use of wine compared to ReactOs in a vm. So I'd like to know about that.

Alternatively, the windows xp source code was leaked recently. All I'd like to know is if there is any possible better path forward, regardless of legality, because Wine seems like a dead end.

Nah. The problem seems more likely to be related to drivers and hardware acceleration. I didn't have Mesa-32bit installed.

After I installed that, it would immediately crash and give some sort of registry error I can't understand in the slightest. It's possible on real hardware this wouldn't be an issue.

Maaaaybe, proton would somehow rectify this, but I don't even feel like trying. This was on void linux.

You're making life a lot more difficult than it needs to be
Just use Bottles, it's on Flathub
Basically a wrapper for handling wineprefixes at its core with a bunch of other useful features
Since I moved my desktop back to Linux a few weeks back I've been using it and have had basically no issues running VNs with it
The only real issue that you can't handle through the GUI in terms of dependencies is Windows fonts, but if you just grab those somewhere yourself and dump them into the wineprefix I've had good success with a lot of things just running out of the box

For context, that was my experience using wine in a void virtual machine. Since then, I've learned there's a big difference between a real gpu and virtualized one. I've also started using vmware instead of vbox, which has been quite the improvement.

I haven't tried cavestory in wine again, but nxengine works easily. And following this(admittedly lengthy) guide https://learnjapanese.moe/vn-linux/ (minus the lutris steps) has led to good results with visual novels, even in a vmware virtual machine(kubuntu).

I haven't seen a case where Bottles would improve things. Just using the same prefix for everything seems better to me.

People have been doing calculus for hundreds of years, and yet there is still no place where you can easily find any kind of calculus problem, in any form, and how to solve it. Why?

This applies to pretty much any stem field except maaaaybe computer science. Finding problems is already hard enough because there's no simple, standard way of typing math notation, and which search engines would be able to understand. When you try searching for most problems, you often only get general tutorials as results. It's maddening.

Windows can be used to type Chinese, which has thousands of characters, yet there is no built-in math notation support.

Students have basically no choice but to pay for services which provide solutions to problems their customers post. And they find problems on those services(assuming they've been posted) by copying the part of the problem statement without any special notation. God help anybody trying to self-learn.

Why are we still stuck in the 90s when it comes to this stuff? How does nobody else have an issue with this state of affairs?

One sages when his post isn't pertinent to a thread's topic, or his post is unsubstantiated. It has nothing to do with being cagey, nor should you infer it as elitist behavior.

The simulation theory is something that's gotten a lot of interest lately. This is used as an argument against atheism, because the simulation theory is just a matter of faith, ergo just another religion.

Why not do it?

How many churches are there that are in favor of free and open-source software? How many synagogues in favor of privacy and encryption? How many mosques in favor of building small, organic, virtual communities, rather than artificial ones on the servers, and existing at the mercy, of vast conglomerates?

There seems to be a need for an actual religion that promotes Internet freedom.

Why not this?

It is an interesting idea. Maybe it would be possible to make a religion out of it. For example, one could say this 'simulation' is filled with secret rules and codes of behaviour that the simulation favours or disfavours, one could use real statistics and skew them or even just make statistics up and so they could say something like '70% of people that took their hat off in the presence of a cow have had an unexpected and unrelated, highly beneficial event occur in their lives that could not be explained whereas 67% of people that have urinated on a cow have died of an unnatural and unrelated death that cannot be explained either, therefore there is a secret code in the simulation where if you take your hat of to a cow you are blessed but if you pee on one you will likely die'.

Does anyone here have experience with ham radio (perhaps even getting a license)? I recently stumbled across http://www.websdr.org/ and it's been kind of fun playing around with it, tuning into random parts of the spectrum and catching people's conversations (it's also mind-blowing that we now not only have enough computing power to do the demodulation and signal-processing that used to be done with dedicated circuits directly in software, but that we can do so in real-time inside a browser). Seems like ham radio is a dying hobby these days, and the only people left doing it are the older generations, but the sort of insular culture is also kind of neat – almost like an imageboard community.

Most of the topics I saw being discussed were people talking about their setups, but aside from the communications aspect there's got to be some other cool stuff you can do with broadcast/receive permission for all that spectrum.

My primary interest in Ham Radio would be due to Broadband-Hamnet. I think it would be cool to host an imageboard using radio in a post-apocalyptic world. Outside of that though, I don't see the point of Ham Radio. To me, it's inferior to forums because the two of you have to actually be available at the same time in order for communication to be successful and due to time-pressure, you can't structure what you want to say as well as you could in a forum.
I understand the technology had a former glory and I do support archiving and preservation of history but it's still generally irrelevant to me as I have little interest in using something purely because it's an older way of doing things.
Ultimately, if you just want to talk to random people around the world, why not just go on Omegle? I don't know if people still use Omegle like they did in the late noughties or early 2010s but nonetheless, I don't think there's anything wrong with it.
From what I've read on the Ham Radio subreddit, it seems Broadband-Hamnet or some technology like it is what's really rejuvenating the Ham Radio scene.
Anyway, for the time being, as I haven't got the funds, I'll ignore it for now but I have to say, I'm greatly looking forward to where things could end up going.
>> No. 2148 [Edit]

In the US doesn't all communication over ham radio have to be done in cleartext (i.e. you can't encrypt things)? How does that gel with broadband-hamnet? It means that you can't do any sort of encryption and that means you can't use almost any of the modern application protocols.
>> No. 2435 [Edit]
https://spectrum.ieee.org/ham-radio was a nice recent article on the current state of ham.

I guess "ham radio" as a community is dying, which makes sense since there are endless ways to communicate these days. Moreover, from a technological standpoint the ability to transmit information over distances via radio is no longer as captivating as it once was, since the Internet suffices for the vast majority of use-cases (especially since you don't need to get a license to experiment with it, equipment is ubiquitous, and development can be done at the software-level).

If you have to endure Microsoft shoving their whole fist up where the sun don't shine because your new-ish hardware either doesn't support Windows 7 or you're tired of worrying about operating systems and decided to just bite the bullet, here are a few things you ought to consider:

In the beginning, there was no reliable way to stop Microsoft's spying unless you somehow got your hands on a clean ISO for the LTSB/LTSC edition of Windows 10. Now there is, through a third party open source firewall called Simplewall. By default it comes with a list of IP addresses to block that Windows normally sends telemetry, keystrokes and other data to. Simply enable them in the blocklist.
Link: https://github.com/henrypp/simplewall

Another project which aims to mitigate data collection as well as to debloat the system is a PowerShell script called Windows10Debloater which disables bloatware applications that have their own data collection, such as Cortana, the Microsoft Store and Edge. (Link: https://github.com/Sycnex/Windows10Debloater).

After running these I managed to get zero networking utilization when I don't run any internet-connected tasks myself, something which was near impossible when running Windows 10 without these things. Keep in mind though that you will probably have to re-run the PS1 script after every major update since those tend to re-enable some if not all of the built-in crapware.

You can also defer Windows updates by setting Windows Update Service from Manual to Disabled in services.msc. To ensure that the Windows Update Service doesn't start without your permission since it can actually do that (believe it or not) you can open up gpedit.msc, then go to Computer Configuration > Administrative Templates > Windows Components > Windows Update > Configure Automatic Updates, and select Disable. This way, Windows will only update when you tell it to.

Yeah this is a lot of hoops to jump through but I think it's worth it to try to stop Windows 10 from just doing what it wants.

I think about this a lot. The half-baked rationalization I am most satisfied with for the moment is that mathematics is so successful at describing the world since it is an enormous repository of arguments; while it may not be the case that every mathematical argument is relevant to real-world phenomena, we are forced to turn to mathematics to find means of concretely describing and articulating what we observe about physical reality. Now that I write it out, though, this revelation seems pretty vacuous.

In any case, yes, it is very interesting that a handful of axioms consistent with how we understand the world could bear so much fruit.

You can actually get the higher-end ones for quite cheap used. For instance, you can get Aerons for $250-$350 if you hunt around a bit. And considering that they last 20 years or so and are designed to be repairable it doesn't seem too outrageous. But I don't know if the Aerons are actually as comfortable as people say they are or they're just overhyped placebos.

>> No. 2315 [Edit]
I was able to test a bunch of chairs in my quest to buy a comfortable one. Here are some quick thoughts, in case it might help anyone else:

* Steelcase Leap V2: A bit overrated in my opinion, I felt "boxed in" by the seat (especially the way the sides sort of curve slightly inwards like a bucket racing seat). It just felt overengineered and heavy, but a lot of people seem to like these so your mileage may vary.

* Think V1: A lot lighter than the v2, and an interesting hybrid between mesh and foam seat/back where they suspend a thin piece of foam on a bunch of metal wires that can flex to mold to your body. But in practice the seat felt pretty uncomfortable, there was almost no lumbar support 9even with their adjustable plastic contraption), and there was no way to set recline tension. I feel like there's a weight threshold to get the metal wires to actually bend, and I guess I was below that cutoff (I guesstimate you need to be > 140 ish)

* Haworth Zody: Currently trying this, I like the mesh back and its lightweight feel. It doesn't have any fancy gizmos like the other two steelcase chairs, it's just a solidly designed chair with all the things you would expect.

Note that the one chair I didn't have the chance to try was the much-hyped Aeron, although I think the hard plastic edges of the mesh seat would have been an instant dealbreaker.

If you're shopping for chairs, it would behoove you to try to find a ushed/refurbished furniture dealer nearby. Depending on your location (rural or urban) this might be easier said than done, but you can usually get chairs from liquidation places or office closing sales for a fraction of their original cost. This guy's [1] reviews of various chairs were also very helpful in identifying things to look for.

These sorts of counterintuitive puzzles are great at forcing you to understand physics. Another one I came across which I'm still trying to puzzle out:

https://www.youtube.com/watch?v=k-trDF8Yldc

Which manifests in the "sailing downwind faster than the wind" thing demonstrated by Blackbird: https://en.wikipedia.org/wiki/Blackbird_(land_yacht)

Ok after some thinking I think I understand this now. There are two main questions to address: why the top wheel counterintuitively spins anti-clockwise despite a force directed from left to right, and why the entire contraption moves to the right faster than the ruler.

The key thing to first observe is that the bottom two wheels aren't uniform in radius. They have an inner and an outer radius (due to the nature of the cotton spoon) which is perhaps more clearly seen in this diagram [1]. This already gives a hint of why it can move to the right faster than the applied force, due to a "gear ratio" effect. However, while the calculations are useful for verifying this quantitatively, it still doesn't give a good intuitive answer, nor does it explain why the top wheel spins anti-clockwise.

The best answer I've seen is courtesy of a post on reddit [2] which I'll quote here for completeness

> For the car to move right, the little wheels must turn clockwise, and the big wheel must turn counter-clockwise. This would give you the impression that the ruler must go left to turn the wheel counter-clockwise. That is true, relative to the car.

>Looking at the construction, one immediately suspects that the size of the wheels is somehow involved. But that isn't quite it. Actually, it is because the big wheel touches the ground wheels on an axle, not the part of the wheel that touches the ground. This creates a situation where the speed the outside of the little wheels move faster (in terms of linear velocity) than the outside of the big wheel.

>So, shifting out point of view to the car, you have a wheel to the ruler, and wheels to the ground, and the wheels are geared such that both surfaces move in the same direction, but the ground moves faster, relative to the car

>So imagine now that the car has a motor, and the ruler is just resting on top. As the car moves right, the ground moves left relative to the car. The ruler moves left relative to the car, but slower than the ground. Th

This explanation also naturally extends to the "downwind faster than the wind" vehicle Blackbird. It's the same principle, where you derive energy from the relative difference in speed between the air (the ruler) and the ground. There should be no doubt that this is possible in the simple gear example, or you can also think of a lever if you like a static equivalent of how you can increase speed (at the expense of decreased force).

But with a propellor in the vehicle, now the linkage becomes a bit more subtle. You have to consider the propellor not just as a flat disk, but consider the actual blades of the propellor itself which take a helical path. Then the issue of gear ratio is manifested between the forward motion of the vehicle and pitch of the propellor. The fact that the wheels turn the propellor in the direction against the wind, means that vehicle can travel faster than the wind (with respect to the ground) while still maintaining the property that a single propellor blade – importantly accounting for the helical path – is traveling slower than the air surrounding it. The parallels to the simple 3-wheel cart should be clear.

Interesting how quickly things change. Intel has been sleeping at the wheel for the past two years with their "tick-tock" being more of a "tick-tick-tick". Of course Apple has hit it out of the park with their arm-based processor. One might optimistically hope this could lead to the resurgence of different isas (maybe riscv?) but we're probably more realistically going to see arm-based processors start shaving off marketshare from x64 ones. Amazon already has graviton as part of their ec2 lineup, and hopefully the momentum from apple's processor transition will lead to better tooling for cross compilations and platform agnostic primitives.
