I recently gotten myself on some books on how to do Java Script again. I came here today to ask what is the programming languages that are worth learning.

Because I think that people still use Java Script but not as nearly as much as other programs. I want to do this on my off time as I look for a job again. That way I can just have something useful other than my knowledge of historic events and wanting to preserve the artifacts.

Hi tech, I run the site New Multitude which often features contributions from leftypollers.

Currently the site is run on a wordpress site that I had someone on fiverr build for me. It's ok, but I kinda want to streamline things and not have to worry about the site. I also want to transition the site to more high quality articles, and put quality above quantity. For these purposes, substack seems like a good deal? I wouldn't have any paywalls and I believe substack lets you use it for free too? I also kinda think that i terms of 'branding' the .substack url is a good one these days


Before I make the switch though, does anyone here want to dissuade me or suggest alternatives?

Sounds like a fad that will fade soon. If you don't have any issues with the current wordpress it is probably not worth switching.

ITT post a tool or tools you find useful when attacking, maintaining access, bug hunting, recon or whatever else. I'll start:

Weevely3 is my favourite out of the box PHP/.htaccess web shell. Its payload is very small and you can sneak it in to many places and has many features that make the job faster, especially with its pivoting functionality
and lastly its modular allowing easy creation and sharing of new functionality such as adding privilege escalation methods and automated further backdoor and persistent access creation.

How do we improve modern cargo trains

>>10898
you are missing the most important advantage of electrifying rail, you can put a relatively simple computer into a rail-car add a small motor and voila , you can send individual rail cars over the rail network like it's a tcp/ip packet. Putting a slightly more sophisticated computer into the rail-track switch, to automatically rout the rail cars is simple enough. It's a little tougher to get good security but if you make the auto-packet-cars small enough they won't do much damage nor kill anybody if they crash into a regular train, but they will help get much higher value out of the tracks and existing infrastructure.

 No.10901

My impression from reading the local railway workers' magazine was that the main issue with rail transport, at least where I live, are the rails themselves. You can buy new, more powerful engines, but they are worthless if your lines are in disrepair and you can't go safely faster than 60 km/h. Take a look at the max speeds on this map: https://www.openrailwaymap.org/

we should split the trains into small individual carts or "pods", put them in a near vacuum tube and making them really fast and with RGB lights that would be cool i tihnk

>why is it a pain
It's very modular (different protocols and tools for sending, receiving, authentication, storage formats, signing to ensure authenticity, spam detection and prevention, etc)
Very easy to misconfigure and end up with an insecure relay that spammers can hack or clueless users can send junk through making it end up on spam blacklists, removal from which can be a pain. Many of these blacklists are even rent-seeking assholes which means they have incentive to block servers and then sell services to promote "best practices" about how not to end up on these lists. This is even more of a danger if your server is sending high volumes of mail (like maybe a company sending out regular newsletters, transactional or promotional email etc)
Way too much of a hassle most of the time.

But if you set it up properly it can work just fine for your personal domain. I run mail services for my domains and they have been running fine for several years now, but mail activity on there is pretty low. So if you really want to, you can set it up.

It is not the same feature at all, I'm talking about fit content, not fit page. I opened the same file on both so you can see the difference, the fit content zoom and scroll automatically as to fit the content and show as little blank space as possible without making you have to scroll at all.

Here's how it looks like, I had actually took screenshot of more pages and from both, but the jannies don't let me upload more than one file.

Do you mean like this? It's called trimming the margins and is supported by at least qpdfview, Okular and emacs' pdf-tools. Maybe others support it too.

But your image just shows fitting to the page's width and that is supported by Evince as that other anon pointed it out.

Does /tech/ participate in the Fediverse? Seems to me that this is the sort of social media we should be trying to get people into, even if social media itself is kinda trash.

I've always disliked social media, but after the news at >>>/leftypol/1066439, I've been considering getting into the Fediverse. You see, I would like the people who DO use social media (basically everyone) to be on better platforms, but I feel I cannot demand that from them if I cannot even use them myself. For instance, it would be disingenuous to ask Comrade Cockshott to start his presence in Mastodon after getting banned from fedbook if I could not be there to follow him and boost his follower stats. So..

So, /tech/, any thoughts on the Fediverse? What are some good instances and communities I could join? What are some people I should be following? What implementations are better, Pleroma, Mastodon, something else?

Also fediverse general.

What are some good file hosting/sharing services in terms of OPSEC? I don't want to use Google Docs or any of their services for obvious reasons so I would like to hear anonymous opinions rather than some website that might be biased towards one service or another over financial reasons.

I'm mainly asking because the file limit here is too small for me.

What's /tech/'s opinion on electric vehicles (EV)?
I want to be excited about them but capitalism has made me weary about tech progress and I fear what could porky do to ruin EVs, like putting DRM on them or something.
Otherwise they're really cool and I'd enjoy a thread about them.

>vehicles design matters more than what it's powered by
And this is why filter technology for ICEs makes emitting as much CO2 as during the production process of Li-Ion batteries near impossible. Vehicle emission regulations are also easier to enforce, than emissions during battery production.
Sadly car manufacturers try to circumvent these anyway and now the most vocal persons of my country think of ICEs and especially diesel motors (even though these emit the least with a standard filter) as "dirty". The state is now in the perfect position to pump car manufacturers full of money for research on EVs and graciously "lure in" EV manufacturers from the USA under the guise of "climate justice".

I'm surprised no one mentioned the safety implications of lithium batteries. By design they offer "less flammable material" than gasoline, yet defective design enabling heat runoff frequently leads them to spontaneously catch on fire https://en.wikipedia.org/wiki/Plug-in_electric_vehicle_fire_incidents

I wish I hadn't made this thread before reading about other alternative fuels. Right now I'm fascinated with natural gas vehicles, they were widely promoted in my country and supposedly there are lots of them in circulation but because most of them are conversions they're invisible unlike electric cars. In the end natural gas is not much of an improvement, it still has significant CO2 emissions and it's so dangerous and awkward to install that natural gas motorcycles are a pipe dream, vid related is a natural gas motorcycle and it's just so awkward to even look at it and because it only has a small tank it probably can't go too far and if you get in a crash it'll explode, what a disappointment.

if you are doing tech videos you don't have to show anything personal, there are youtubers doing tech videos and you only see their hands and their tech projects like most of bigclivedotcom videos. You can go even further like nurdrage, where the presenter wore pantomime gloves and had a audio modification to change their voice.

if you are doing computer stuff you probably can get away with only showing your screen-capture.
There also are text to speech programs that let you create realistic sounding voices, you can get a a few good voices for festival that are reasonably priced, and don't need a server in the cloud to work, if you are really squeamish.

Stallman was also a genius, if you look at the free software movement, a lot of people are talking about moral principles, ethics and ideology, it can become preachy at times, but if you look at the software that is created under free software licenses, they are extremely universal and neutral peaces of technology that basically just perform the technical task they are supposed to do and nothing else. If you use corporate consumer tech, you are buying into a corporate vision of how to do things, none of the tech just performs a task, it always comes attached with unrelated baggage, and sometimes even cultist stuff.
