I wanted to look at the only wiki about systemspace which actually has some more in-depth information about what happened, but it's not hosted anywhere online. Instead, there's this megadownload of the wiki's contents https://mega.nz/file/I8kgFa5B#ddOoO-NPrDM9r9HDS9cdWxA0KdL5bmfJSCYPhEub_To
The problem is I don't know server shit. The furthest I got after a few hours of messing around was with wamp server 3.2.3, but I get this error and I have no idea was the problem is

Has anyone set up a btrfs or zfs filesystem? After reading this article, I thought that when it came time to upgrade my computer's main disk drive (i.e. the one the OS is installed on) I'd do it by buying a new SSD, making the filesystem one of those two, and installing a whole new Linux distribution on it and copying over the user files I care about. (Currently it's a Linux on a 250 GB SSD with ext4.) There were also some fancy partitioning schemes I wanted to learn about, involving putting /boot and /tmp on their own partitions, putting the user home folder on its own partition, but they're less important to me.
>> No. 2282 [Edit]
>>2281
I've been looking into it – from cursory readings it seems ZFS is a more "battle-tested" technology, and there's more established tooling around it. I'm still a bit confused by all the zpool stuff, since there are apparently some limitations – things like not being able to change the pool size after you create it (but apparently this can be done if you swap an existing hard drive for a larger one, just not adding a new hard drive)? I feel like there's a lot to read up on and understand though before I'd feel comfortable using it (mainly since I don't want to be blindly poking around when dealing with filesystem level stuff).

Also, does anyone here happen to know how exactly "raid-z" differs from a zpool? Are these two orthogonal things?

But yes the "essentially zero-cost snapshots" and copy-on-write are absolutely wonderful technologies that any modern filesystem should have – even Apple recognized this and replaced their aging HFS+ with APFS (although I still have a soft spot for HFS+ just because of how conceptually simple it is to understand; and their workarounds to achieve posix compliance are a glorious hack).

Debian stable, nowadays. I used to use Arch, but systemd and various other shit came along with a steady downturn in general, so I jumped ship to one of the only remaining (at the time) options in Debian. Howewer, a few months after that, Debian made the decision to eventually switch to systemd as well, so I'm not sure where to run once the current stable release becomes obsolete.

Realistically you don't encounter many OS level bugs these days unless you're doing something weird, yes.
I have an idealized image from what I've heard of live-hackable Lisp and Smalltalk machines of a system where the source for everything is easy to bring up and understand and modify. Obviously not even OpenBSD fits that bill, anything that simple would be a toy OS unfit for normal use. But it's nice to daydream about, I suppose.

This is a really interesting project. I wonder why it hasn't caught on more.
>Like other device driver interfaces used in Operating Systems today, UDI defines an architecture and a set of APIs for use between the driver and the surrounding system. This allows drivers and OSes to be developed independently. UDI goes a step further and provides APIs that are OS-neutral and platform-neutral, allowing multiple OSes and platforms to use the exact same driver.

Surprised this doesn't exist yet.

So what do you think the future of AI is? Do you think eventually, we'll be able to give an AI general instructions and have it program something based on that? Like "write a play station 5 emulator" and then it would actually be able do it? Would that be a good or bad thing?

You could go under the assumption that there is some algorithm in the future that can have the AI adapt to situations very quickly. If the AI is tasked to doing something, it'll find any option to keep doing it. If the AI is trained to attack or learns on its own that this is an option, it may be possible. For now, reinforcement learning is incredibly slow and stupid, so it isn't possible for an AI to learn this on its own. That being said, someone could train attacking humans as an option or there is a better or extremely improved method for reinforcement learning and the AI is capable of learning in real-time. I doubt this will be possible in an extremely long time, but who knows what the future holds.

Here's a related question: do you think humans will interact with their computer via ai in the future? Voice commands do exist now, but they aren't that smart. In the future, could a person say out loud
"open up directory x" and the ai would be able to do that for them? Or maybe even "copy file y in folder x". If the ai isn't sure of something, maybe it could even ask follow up questions.
>> No. 2278 [Edit]
>>2277
I suspect this will be possible (in fact it's an easier task than general AI since the set of things you can do with a given application is limited). But for experienced users, interacting directly with the computer is always going to be quicker than providing mouse commands: i.e. I can drag/drop a file to the trashcan faster than it takes me to say the words.

It might be more useful for running complex queries though: "trim this video to the first 10 seconds and create a gif from that" is a lot easier than trying to remember the right command.

There are definitely a lot of older sites still online on the Japanese web that are made for 4:3, but I think a lot of the newer sites that render correctly do so in response to mobile phones demanding greater webpage scaling so that no single aspect ratio is the "correct" way to view something, or at least that the site works with the greatest number of aspect ratios as possible.

Belated response, but I really appreciate your thoughtful responses. The CI-aspect (as opposed to simple unit-testing) is something I often forget about since nothing I work on necessitates such infrastructure. In your opinion, is general experience with the aforementioned techniques something that's expected from graduates of CS (and related) degrees, or is it something that's rather learned on the job? (Ignoring the differences in infrastructure across organizations, hence "general".)
>> No. 2283 [Edit]
>>2280
>The CI-aspect (as opposed to simple unit-testing)
In my mind "continuous integration" is more about the infrastructure and is orthogonal to the issue of system/unit level tests. For instance, you could just have your CI scripts run all unit tests upon a commit. Unless your job deals with setting up such infrastructure, I don't think end-engineers ever have to explictly think about CI itself, since it's merely an automated mechanism that runs the tests.

> something that's expected from graduates of CS
(I haven't spent enough time in the industry to say for sure so take the below viewpoint with a grain of salt)
Considering that most university graduates barely have experience writing good unit tests, I doubt that new hires are expected to be able to think about system-level tests at all. In particular, while you can assume that graduates will at least have some basic exposure to the idea of unit tests (perhaps they might have had to write some themselves for an assignment, and they'd certainly be familiar with testing algorithms for correctness given the prevalent use of autograders), system level testing is something that very few students will have needed to think about given that in university, projects are usually small and simple enough that there's no need for this. It's only when you dive into things that have to deal with networking, databases, RPCs, etc. that the limitations of unit tests begin to show and it becomes worthwile to consider bringing up an entire sandboxed environment. (Somewhere in between that continuum of unit tests to entire sandboxed instances, there's the in-betweens of in-memory simulations, RPC replay, and perhaps even more that I'm not aware of).
>> No. 2284 [Edit]
Functional and declarative programming is a bit of a mindfuck coming from an imperative mindset. Doesn't help that keywords and concepts have differing meanings between the two paradigms.
Tangentially related, StandardML is pretty fun, and mlton's FFI to C looks nice.
>> No. 2285 [Edit]
>>2283
>I don't think end-engineers ever have to explictly think about CI itself, since it's merely an automated mechanism that runs the tests.
This assumes a definite bifurcation of dev-ops and the engineering that which the former services, right? In any case, I'd imagine end-engineers must be literate with regards to the system that orchestrates the integration and unit tests: Someone must map the output given by the CI system to a resolution for the problems reported.

>It's only when you dive into things that have to deal with networking, databases, RPCs, etc. that the limitations of unit tests begin to show and it becomes worthwile to consider bringing up an entire sandboxed environment.
Would you think it would be worthwhile to have colleges; assuming you agree they should be the main producers of these practitioners; offer classes to simulate this situation and ones similar to it? Or perhaps such complexities don't fit into the scope of a semester-long lab.

What's the difference between that and 2-clause BSD?

>>2241
The 2 clause BSD has no copyleft. Derivative works or even direct copies don't have to include the part of the license which allows for free usage(which isn't clearly defined in the 2 clause BSD). The only thing you have to include is the attribution to the original writer(copyright notice), the conditions, and the warranty, but not the part which lets you do whatever you want to it within some parameters.

This license also doesn't require the name of any copyright holder.

To clarify by free you mean libre or gratis? The 2-BSD states

> Redistribution and use in source and binary forms, with or without modification
which seems to cover the libre part for source distributions.

If you mean gratis, then your license mentions "and/or sell copies of the Software" and allows binary distribution, which would prevent that.
>> No. 2244 [Edit]
>>2243
No, I don't mean gratis. Free as defined as
>deal in the Software without limitation the rights to use, copy, modify, merge, publish, distribute, and/or sell
Somebody could sell their version for money, but the person who bought it would be able to do all of the above with their copy after buying it. Binary distributions can still be copied and sold. Somebody could also de-compile binary software and/or otherwise modify it in some way.

The bsd license does not require this part
>Redistribution and use in source and binary forms, with or without modification, are permitted provided that the following conditions are met:
To be included in derivatives and copies of the software. You only have to leave Copyright <YEAR> <COPYRIGHT HOLDER>, the list, and the warranty.

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.
