If you can't install your own firmware on your "smart" thermostat, so you have total control over your heater, you have to rip it out and replace it with a mechanical valve. The fact that this was even physically possible proves criminal intent.

Oh god
oh fuck

I'm retarded.

I've never been tech-savvy, just a pleb consoomer and user, never digging deeper than what was on surface level.

But it seems to be, based on what I've been hearing for the past two years, that those who don't have a workable knowledge of it will simply be considered the illiterate of the 21st century.

What bare bones basic, and I'm talking like Primary School shit I'm just that dense, level stuff should I learn?

So far I've got:
- Linux (no fucking clue how I'm going to learn it)
- Python (seems accessible and is used in some GAN AIs which I find interesting, so kinda motivating)
- Ruby (it's easier Python, is it really worth it then?)

That's not how it works, ISPs and gov are not important players here. Data about us is collected by trackers and then resold by brokers to whoever. Of course that data is messy and takes some (automated) work to tie different data clusters to one single person (e.g. this facebook user is the same person as that myspace user from 10 years ago).

Technically a company could just buy that data on their own (unlikely) or use some kind of 3rd party service too look into your internet history. Kind of like a privatized social credit score or a psychological profile. This is already used by banks and insurance to calculate your trustworthiness. But when it comes to employers, right now they mostly use more primitive methods like simply googling you and checking your profile on Facebook or Twitter.

If you want to hide something from data trackers then Tor is a good bet IMO, as long as you learn how to stay uniform and not stand out. And especially don't login into Facebook and in the same session visit whatever you want to hide. Compartmentalization is key to a good opsec.

bro we've kinda passed that point. my godfather who is a complete autist managed to create his own 3d printer from pieces, it's right in his kitchen next to the sink. I have no idea how it exactly works but it looks crazy and apparently he just draws the stuff he wants printed out on a computer, pops in a few plastic plugs and that's it and this was about 10 years ago. His rich and hot as fuck wife divorced him after about half a year when she realized he wouldn't stop working for 12+ hours per day because he's now married. So yeah, besides extreme technerdness all the way since kindergarten being basically a requirement you also need to make these kinds of sacrifices to get close to those sort of levels.

How do we fight back against the crypto-tards? They currently have a monopoly on credibility at the moment and I'm fucking tired of it. With the increasing escalation of tech censorship over the last several years we have ourselves a golden opportunity to grow the communities of censorship-resistant decentralized federations, and the crypto scammers keep managing to siphon people off into their unsustainable pyramid schemes. Every time their spokespersons get thrown a softball interview and every time they seem completely incapable of articulating and justifying their system because, gosh, it's just too darn complicated for the average person to understand! And it seems like nobody is paying any fucking attention when this happens routinely because blockchain and electronic tulip bulbs are some magical mysterious technology that you have to do a doctoral dissertation to understand, but just trust us it works. How do we fight back against the anti-intellectualism of crypto woo?

it's a false dichotomy only if comparing random pyramid scheme shitcoins to paypal, but if you want to buy anything on the internet, and don't want to use a bank card (or don't have one), then cryptocurrencies are the way to go. They have a legitimate use here, mostly though for buying stuff you don't want traced. Not even just drugs. Also it's just effective for internet transactions. If you use monero, it's reasonably fast and anonymous. Way better than handing a website your whole bank card credentials and full name and address.

I don't think software 'engineering' can be regulated as linearly in other engineering disciplines. Laws of physics and heuristics humanities gathered are static whereas exploit writers are always adapting to changing environment. They are always interested in what existing tools and defense mechanisms cannot do not in what it prevents. Software engineering actually have lot more in common with 'financial engineering' when it comes to regulatory challenges and we all know how responsible they are.

Security through correctness has always been the way but even after Microsoft's decade worth investment in formal verification tools we do not have killer language or toolchain that is reasonably productive enough to be adopted in mass scale. Rust could fit the bill but I am skeptical of it for obvious reasons.

Wait a minute, the compiler optimizations that reduce the vulnerability to exploits don't have to be linear regulation, you are taking my building-code metaphor way too literally.

>Software engineering actually have lot more in common with 'financial engineering' when it comes to regulatory challenges and we all know how responsible they are.
No, lawyers write code that is executed by judges, bureaucrats and functionaries, not processors. Brains are not pure logic interpreters. Legal code does not work like software.

I know about MS's code quality project, but you can't expect a big soul crushing corporation to foster real innovation. There is no way anything new could pass through the membranes of corporate administrations, too many people have made careers out of managing the half broken mess.
>Rust could fit the bill but I am skeptical of it for obvious reasons.
Yes that is the popular example but there's no reason other compilers can't have functionality of this type added. or you could even try to have a pre- compiler as a separate insert into the tool-chain.

what ? powerful language that can be proven formally like LISP exists, they're just an unnecessary headache for most applications, and proving programs simply cost way too much when you can just fix it when you see its broken.
We will never, ever have a "reasonably productive enough" way to produce formally verified code, because its way too hard, long and costly.

Don't certain sectors (automotive, locomotive, aerospace, medical, etc.) have their own "building code" style regulations? I did an internship at a company that worked on embedded software for railway signal control and they did have a very specific coding style and some functional requirements like everything had to be redundant. But I am not sure if these were state mandated or just the railway company wanted it this way.

I'm specifically talking about defensive programming and how is it similar to law makers failure to come up with sound plan to restrain hedge funds and other market makers not how human minds compare with processor or how legal frameworks can be compared with well defined runtime environment that runs binaries. Beside I said 'financial engineering' as in quants who have to price derivatives why are you even writing this? Wind will not blow in specific airflow with malicious intent to collapse bridge you built but rest assured traders competing with you is looking at everything you do waiting for opportunity to exploit weakness in your model or execution plan.

>MS rant
I'm not talking about their code quality project. I am pointing at their research efforts and its results on functional programming (their ocaml dialect F#), strong types (typescript) and formal verification framework (F* and obviously Z3). They all deserve some amount of criticism but just shrugging them away as corporatism is impotent.

Gemini markup doesn't give you many options for formatting, just some headings lists and links, and clients can render them all differently.

You can get that with one fiber-optics cable. In principle they just need to bond a led on both ends of a fiber optical strand and put a signal converter chip on both ends of the cable to make it compatible with electrical ports. Eventually it could become cheap enough to stuff chips into cables, especial if the led and signal converter are integrate into one tiny piece of silicon, and you do something clever with the fact that microchip circuits are affected by light.

Nice, now I have to carry my fucking phone around with me every time I want to check my fucking work emails because some prick at IT decided to force everyone on to two-factor authentication in order to interact with the mail server. So much for choosing to opt out of mass surveillance and the socially-malignant perpetual connectedness of carrying a phone everywhere. So much for email being convenient.

It disgusted me when Google and other Silicon Valley monopolies started forcing 2FA on people because I see it as little more than an excuse to coerce people into giving up contact information to better track and surveil them. What's the real deal with two-factor authentication? Why is it seemingly impossible to find an article critical towards it on a simple web search?

We need to break this search engine monopoly over what information is available. It's amazing how you can't find anything critical about entrenched IT shit like "cloud", or 2FA or any reliable information about user data being sold except in obscure mailing lists and niche tech communities.
I hope searx takes off.

Also, "IT departments" are cargo cults a majority of the time. Just blindly following whatever is "recommended" to them through their infra provider like IBM or Oracle, or the cloud providers like AWS or Azure these days.

Because 2FA is a good thing. Most people use insecure or reused passwords. Any competent IT department requires it because it massively reduces the risk of account compromise.
