I recently switched from vscodium to Sublime 4 on my ThinkPad primarily due to performance issues. Having never used Sublime for more than a few minutes, I was quite interested in seeing how it stacks up.
In short, well enough. As implied, VSC doesn't play well on my laptop because of Electron and the machine's poor graphical power, but I've used it nonetheless due to it featuring the best support (via an extension) for the language I use. Sublime, on the other hand, is quite snappy, and its startup times are great.
Without additional packages, Sublime supports my favored language's with syntax recognition, okay-ish autocomplete, locating of definitions, snippets, and basic integration with the standard build tool. Very much of a pleasant surprise, and unlike the VSCode extension, nothing breaks, forcing one to reload the window.
Sublime is not without faults, of course: no built-in terminal, the best 3rd-party package providing terminal panes/tabs isn't that good, the built-in vim emulation and third-party packages providing it leave much to be desired, and there is no support for the language server protocol as far as I know. The latter would allow me to use much of what the VSCode extension provides, but I'm sure implementing the LSP is quite the task, and one wants to ensure it won't affect performance.
Nonetheless, I find Sublime to be pretty good, and I'd buy a license if I wasn't a poorfag. Even without LSP support, if the developers added a built-in terminal, and there was an updated third-party package that integrates with neovim, I would be a very happy camper.

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.

Might as well make a general thread for this.
Article on search engines with their own index:
https://seirdy.one/2021/03/10/search-engines-with-own-indexes.html

I'm interested in making and hosting a curated search engine(hand picked domains to index) with the following feature set:

Site specific searching
Date range specific searching
Exact string mandating
Image Search
Maybe document type specific searching too
Maybe a synonym system

After hours of research, I still have no idea where to start, like whether it'd be better to make everything from scratch, or cobble together things that already exist, and what if anything I'd need to make myself with the latter option. This post pointed me in a general direction >>/ot/36920 but both Solr and Elastic Search seem meant for searching internal text based documents. I found virtually no information about using them in this kind of context.

I don't think using searx would give you much in this case, since it is only a presentation layer. See this pr for instance that shows how to use searx as a frontend for recoll: https://github.com/searx/searx/pull/1257/files.

So at best you can use searx as a nice UI for whatever solution you come up with, but that's not really the hard part here.

>So maybe it could receive things directly from an index which has no front end of its own?
To be clear, searx is just a pretty UI. All it will do is query a backend for you and return the results in a pretty way. I don't think it is capable of doing any sort of ranking on its own, and certainly will not handle the underlying FTS process.

To make a search engine, you need an underlying data source, an index of the data (e.g. posting list in the most simple case), then retrieval algorithms on top of that (query rewrite, stemming etc.), then ranking algorithms to sort the returned results. Luckily there are already projects out there which have taken care of building these things, the only thing is putting them together.

Btw good post on Yacy, that kind of confirms my fear that using Solr for this is basically enterprise-tier overkill. We're not building a distributed fault-tolerant system like Google here, we just want something you can chuck on a raspberry pi connected to a NAS to crawl and index a few thousand sites at most. Sadly I think that Solr/Lucene probably has the best algorithms for querying and ranking that you'll be able to find. So I guess to me that indicates that suggestion #3 is the way forward: try to concoct your own search stack by combining a crawler coupled with either sqlite FTS, Lucene (which seems less daunting than Solr as shown by that lucene-grep project), or one of the other FTS engines I mentioned.

Well like I said it's pretty much just the UI layer I'm referring to when I say frontend. E.g. the thing that takes the json of results or whatever and lays them out nicely. This is really the most trivial part, so it's why I said you shouldn't focus on it. But yes, once you get to the point where your search stack is up and running and you can send it a request and have it return the results in some formatted manner (either a bunch of rows or a json or whatever) then you can throw a searx frontend on top of that.

As for what you need to do go get solr to work for your use-case, I have no idea. I've never used Solr. But if it's anything like other enterprise scale™ apache software then it's going to be a lot of config files. Maybe start with some tutorials and just see if you can get it to index some local files. Once you get that working, see how you can integrate a crawler to fetch the documents. I've read that Solr has an inbuilt crawler, but that Nutch also used to be the defacto choice to use with Solr.

I found this https://www.cs.toronto.edu/~muuo/blog/build-yourself-a-mini-search-engine/ which might be a good start, but it wants you train your own ranker(!?!) Maybe google around and try to find some other tutorials, and you'll probably have to read a lot on solr configuration in order to figure out the right dials and knobs to set.

Some other alternate search engines: gigablast and marginalia. Both are good if you actually want to _explore_ the web without every result being SEO gamed linkbait.

At this point Google's only strength is the size of their index. Their query rewriting and "NLP" based ranking make actually finding organic content terrible. I'm sure a part of this is due to the prevalence of SEO tactics, but if they really cared they would easily penalize against this: they could trivially apply transformer based techniques to detect superficial fluff content, or content that's just copied from more authoritative sources.

What do you think about the open source, UNIX-inspired Fuchsia(aside from it being developed by google). I am an ignoramus and windows user, but in spite of that, Fuchsia has(or will have) a few things that seriously appeal to me.

>Zircon is the core that powers Fuchsia. It is composed of a microkernel and a small set of userspace services, drivers, and libraries necessary for core system functions such as booting.
>Fuchsia’s filesystems live entirely within userspace. They are not linked nor loaded with the kernel; they are simply userspace processes that implement servers that can appear as filesystems. As a consequence, Fuchsia’s filesystems themselves can be changed with ease
>Due to the modular nature of Fuchsia’s architecture, it is straightforward to add filesystems to the system.
>Zircon is an object-based kernel. User mode code almost exclusively interacts with OS resources via object handles.
>In Fuchsia, almost everything is a component and it is the unit of executable software... Components can only use shared libraries that are included in the same package as the component... There is no concept of inter-package dependencies
>A given release of the Fuchsia platform typically supports multiple ABI revisions, which lets the platform run older applications
>This document proposes a mechanism for running unmodified Linux programs on Fuchsia... the Fuchsia system does not impose an opinion about the internal structure of components. In order to interoperate as a first-class citizen with the Fuchsia system, a component need only send and receive correctly formatted messages over the appropriate zx::channel objects... The programs are run in a userspace process whose system interface is compatible with the Linux ABI. Rather than using the Linux kernel to implement this interface, we will implement the interface in a Fuchsia userspace program

I like that it uses a microkernel, the filesystem implementation is so flexible, the kernel is object-based, and there's no possibility of dependency hell. As a windows user, I can't really understand

> Any person or group with sufficient time and motivation could make a browser based on chromium that suits their tastes, privacy, ui and feature-wise
Having a browser "based on chromium" is really no better than chromium itself, and theoretical possibility doesn't bear out in the real world. Unless you're ok with rebasing to older version of chromium and using that for perpetuity (which might honestly be fine if you disable js), the efforts required to continually rebase to HEAD are pretty high. In fact as far as I'm aware blink (the rendering engine) and the overall security model of Chromium are really tightly coupled together, so much so that you can't choose piecemeal which pieces you want, it's all or nothing. Now I guess it's "theoretically possible" that maybe someone can go through and uncouple just the rendering engine out, but the fact that no one has done it makes me thing it's a non-trivial task. It'd be easier to just work with webkit. But that opens up another can of worms, because Apple intentionally cripples webkit in other regards to push native mobile apps over web apps (I'm not a fan of most PWA's anyway, but just showing that it's not an easy battle to win)

The only greenfeld rendering engine I've seen is that experimental one by Ekioh, and it's a sad state that the most innovation here has come from a company targetting set top boxes.

>Fuchsia will be around regardless of what happens to google.
Again, just because a project is open source doesn't mean that it's immediately adopted by the community. While I'm willing to bet that if Google dies blink will live on in some incarnation (after all, webkit has survived this long), I think it's unlikely that fuschia will. In fact it's more likely the hobbyist ones such as Haiku will survive longer, because it actually has a userbase that's excited to use it and cares about it.

Or to take another example, XNU (/Darwin) is technically "open source" but we all know that it's really just at Apple�

It's not appealing only because it's interesting. I might as well use Singularity if that was the only thing I valued. You may be completely right that things will turn out like they did with Darwin, but for now I'm optimistic. Even Chromium OS is open source, so Google is different from Apple in some sense.

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.

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.

And yes, you can adjust the recline angle as well as "disable" it completely to allow for it to be similar to a rocking chair.
>> 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.

If you're on a hidpi screen antialiasing is unnecessary anyway. osx disabled it a few versions back

It also looks slightly better on a CRT, if you're running one for some reason.

Didn't they disable only subpixel AA (keeping grayscale by default)?

yeah you're right, my bad. When I played around with subpixel vs grayscale only, the only noticeable difference on the hidpi screen was that with grayscale-only aa, fonts were a bit thinner.

Some Drexel students tried making something that could "anonymize" text input, but it doesn't use machine learning.

Hm it doesn't seem like it automatically does the anonymization yet. As of now it seems to just highlight the distinguishing features which the user can manually edit.

Maybe something like this:

Take your input sentence, "modulate" it with a random sentence to get a semantically equivalent but "encoded" version of the input.
