This kind of blew my mind, the fact that something we built is out so far, even if it's just a probe from the 70's. I know it's slightly old news, but considering how long Voyager 1's been out there I don't think a week makes much of a difference.

Far too much of the stuff I need sporadically requires js for me to disable it automatically.

Firefox ESR has been pretty bad for a long time now, but I'd still rather use it than Chromium. One thing that concerns me about switching to one of the forks is whether they get timely security updates.
For downloading large files, there's megadl, which is part of Megatools.
I do. Disabling JS breaks many websites, which is a pain. >>/ot/33997 and >>/ot/37266 have been pretty useful, even though some functionality is still missing or partially broken with them. The public Invidious instances in particular tend to be somewhat flaky, which is why I hesitate to link people to them.
Couldn't you disable it for general web browsing and only enable it for financial stuff? You could set up separate browser profiles for this.

I use pale moon and switching pale moon profiles is a pain and requires restarting the browser or screwing around in ways that break its interaction with other apps.

Cool I didn't know about teddit. There's also "" which they still seem to keep alive: it preserves the older layout and works mostly fine with JS disabled. Although they've been caught doing shady stuff before [1] so I should probably switch to that.

>Couldn't you disable it for general web browsing and only enable it for financial stuff
Not him but I think he was saying that he didn't even know that the site required JS to avoid tripping the fraud detector or whatever, so he didn't think to enable it. I've noticed this a lot – sites just break in random ways, and if I hadn't used them before disabling JS then I wouldn't even have realized that some dropdown or feature was supposed to exist. It'd be nice if all sites at least supported the noscript tag to let you know that some features are missing.

I was trying to get a program I always use to do something for python 2.7 and it wasn't supported anymore. Looking up the changelog discussions, I saw a poster say "We shouldn't support such ancient distros". Christ... it's really bizarre to me just how much the attitude among programmers is now. Granted, decade old software tends to be forgotten, but I have a hard time thinking of 2010 as "ancient", even as far as tech goes. Guess this is just me griping, but damn.

I don't know, but there's a growing philosophy that old digital technologies should be forcefully cut out from any currently updated projects. Windows 10 for example has some serious fundamental flaws that make windows 7 look comparatively like a masterpiece, yet it's being prioritized so heavily that now people are cutting windows 7 support from their projects. This in particular is infuriating, to especially because when I'm not on a linux machine I want to use windows 7. In my brief stint with windows 10 I discovered some horrific design flaws regarding path variables, registries, and worst of all administrator permissions. As it turns out it is relatively easy on windows 10 for a file to revoke absolutely and forever any access to any users including the system user itself. This is, particularly, unpleasant when said file is malware.

I found something called Gobolinux which looks kind of interesting because the file system is more intuitive. This system allows you to have multiple versions of the same software.
>GoboLinux is an alternative Linux distribution which redefines the entire filesystem hierarchy. In GoboLinux you don't need a package database because the filesystem is the database: each program resides in its own directory.
>In other words, instead of a package manager placing executable files in /usr/bin, libraries in /usr/lib, and other resources in /usr/share, a program's files are all stored in one tree, such as /Programs/Firefox or /Programs/LibreOffice. This way the user, and package utilities, can remove software by deleting a single directory rather than keeping track of where individual files have been installed.
>Through a mapping of traditional paths into their GoboLinux counterparts, we transparently retain compatibility with the Unix legacy. There is no rocket science to this: /bin is a link to /System/Links/Executables. And as a matter of fact, so is /usr/bin. And /usr/sbin... all "binaries" directories map to the same place. Amusingly, this makes us even more compatible than some more standard-looking distributions. In GoboLinux, all standard paths work for all files, while other distros may struggle with incompatibilites such as scripts breaking when they refer to /usr/bin/foo when the file is actually in /usr/local/bin/foo

On a review from 2009, I found this comment which is really illuminating and illustrates a kind of mindset that seriously pisses me off.
>Okay, when I first saw the directory tree, I freaked out. That's, well, scary. Come on, can we be a little more civilzed? We don't need to type "system", do we? "sys" will do.

> because the filesystem is the database: each program resides in its own directory.
That sounds really similar to how osx's container system works. Each application is assigned its own container in ~/Library/Containers so it's hermetically isolated (osx enforces that an app doesn't write outside its container). In fact even without containers osx has a general rule: preference plists go in ~/Library/Preferences, application-specific crap goes in ~/Library/Application Support/bundle_id, and the application itself is basically a self-contained bundle in /Applications. Almost every app uses this structure, and the only ones that deviate from it are (surprise surprise) apps ported from linux (*).

>apt and yum has resolve this problems ages ago
>To me, the issue of managing applications for GNU/Linux is rather a done deal.
Ha! Definitely a "done deal" that they invented (at least) three different container formats to work around how much of an issue this is (snap, flatpak, appimage). I'd argue that the whole docker craze generally came about from the difficulty of deploying applications because of dependency hell. The holy distro package manager works fine if you stick to the paved road (and are ok with obsolete, out-of-date packages), but the moment you want to install something that's not on there, good luck running around to get the right versions of the libraries you need. And pushing the burden back on the developer to create a deb package or yum archive or whatever is a terrible idea, because the packaging steps are tricky enough that nobody's going to bother.

>Can remove software by deleting a single directory rather than keeping track of where individual files have been installed.
That's the key issue. You need developer buy-in, which is basically non-existent in the linux world. There's the XDG spec but even that's rarely obeyed by applications. It's more of a social issue than a technical one, since getting the linux guys to agree on a standard.

Legal questions are fairly local, you can't give a real answer without having at least a specific country, even a specific state, in mind.
Very generally though, there needs to be intent to commit a crime. And since there's legal eepsites (most of them, even) the more act of using i2p cannot be intent.
And to even get there, they'd have to know what content you're routing in the first place, but that's heavily encrypted.
I2P does not itself contain data storage. There's Lahoe if you want that, but I'm not sure it even works anymore.
>> No. 2187 [Edit]
By distributed data storage I meant stuff like torrents.

Zeronet, perfect dark and the work in progress safenet(maidsafe) are entirely reliant on distributed storage.

I remember hearing stories about people who ran a Tor exit node and were contacted by the three letter agencies a few times for suspicious activity, but upon seeing that they were only running an exit node they were off the hook. I don't know how true those stories are, and running entirely within i2p is probably safer than running exit nodes. I think the risk is fairly trivial though since I haven't seen any stories of people arrested for using Tor for legitimate purposes, and i2p is even more obscure.
>> No. 2189 [Edit]
>Tor exit node
That's why you should run hidden services and avoid using Tor to browse other websites. However, there's a guide about that on the Tor project website.

What are your thoughts on alternative web protocols like Gopher and Gemini?
We're living in the dark ages where modern webshites are obsfucated behind multiple scripts and horrible web designing.
>> No. 2174 [Edit]
My thought is that they have low adoption rates, which means standards that advance at the pace of a dead snail. People fill their sites with slow, pointless/malicious scripts and bad design because they can. People can also choose not to do those things. "Quality" via stringent restriction is unecessary and misguided.

I've tried gopher before, and it really does all it needs to (there's even an imageboard available, 1436chan, gopher://
I like how it forces everything to be usable be text-only browsers, text being the universal interface.
Making a gopherhole is also fun because it's so easy. It is what the web should be.
If Gemini is pretty much that but in encrypted, then I'd probably be on board as well, but I haven't tried it yet.
>> No. 2183 [Edit]
I really like Gemini. I believe Gemini has some kind of scalability issue however so it could never become a replacement for HTTP. Nonetheless, I intend to use it myself at some point. I do like the idea of forcibly keeping things simple.

Back up your data, wipe the HD, and restore from scratch?
You can back up your data by booting from a linux live ISO which should then allow you to mount your HD and copy files off of it.

Can no longer edit, but if you want to be really safe then you should clone your HD to another one before wiping it. That you have a backup for the future which you can retrieve files from if you need it.

Mozilla has shifted from focus on the web ecosystem to being more of a "feel-good" organization that wastes money on random crap.

Marketing works, to a degree - but it's assuming there are no right wing programmers with enough talent to roll their own system, and considering what's considered "right wing" these days, that's certainly an erroneous assumption. Hell, there's Loki, which got started by the guy that defended White Lives Matter being on I2P.
Isolating peers:
Only works in that it keeps people from interacting with icki opinions on accident. You can't prevent Person A from peering with Person B in general. You'd end up with 2+ mostly separate networks. They even quote proof of this with the whole Fediverse thing.

Honestly, the thing reads to me more like someone wanting grant money, for which social issues are great because it's easy to make the "problem" understood and you don't need to deliver measurable results.

All v3 Onion Addresses Down After Attack On The Tor Network

I was pondering just yesterday what prevented DDoS type attacks on Tor. The type of attack mentioned in that post seems to be targeting the bootstrap nodes from which info about the relays is obtained.

Another type of attack alluded to in there is a more standard type of DDoS like you might see on the "clearnet." The fact that crypto operations are inherently expensive (to connect to a hidden service you require the other side to build a circuit to a rendezvous point) seems like it should make traffic amplification attacks quite feasible. Even worse, someone with a global view of the network topology could possibly use the DDoS as an opportunity to discover the server hosting a hidden service (find the "hot" node with a lot of incoming traffic).

Does anyone here have experience with ham radio (perhaps even getting a license)? I recently stumbled across 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.

I think the questions are actually drawn from a fixed pool which they publish ahead of time, so worst case you can just brute-force memorize them, although from a pedagogical standpoint that's not very useful for fundamental understanding.

I also realized I never actually looked through the question set before: I just did, and the questions seem to be divided into five rough sections
* Trivia - FCC Rules, descriptions; Operating Procedures
* EE knowledge – Radio wave characteristics; Electrical principles; Electrical components
* Basic Antenna Theory
* Physical(?) knowledge – Station equipment; Electrical safety
* Signals Knowledge – Modulation modes

The trivia is stuff you've just got to memorize since they're just arbitrary conventions. The physical knowledge is stuff you can probably study last since it's basically an application of the theory things; for instance, if you learn the basic circuit theory you'll be able to get most of the electrical safety ones correct. The difficulty of the other four probably depends on whether you've already been exposed to those topics.

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.

Ironically, unless everyone does it you'll stick out the most. What would be neat is a technique that makes use of a GAN-sort of thing that will "normalize" any input you give it, making it impossible to distinguish different users. Maybe this already exists in the literature somewhere, but given that things like word-vectors and GPT already perform some sort of dimensionality reduction, there's probably a way to go from "input sentence" -> "sparse representation" -> "normalized input."

Unfortunately there's an inherent limitation/asymmetry in that no amount of normalization can remove distinguishing features based on content. For instance, if poster A talks about a specific technology a lot, and you come across someone mentioning that same technology on another board, there's a very high chance that you've run into poster A. And there's no way to normalize that since the content being talked about is inherently identifying.
