AMD Zen 3 Launch
Who else here more interested in this than burgerstahn electoral politics?

The FX series were the last AMD CPUs without their PSP coprocessor, a blackbox running unaccountable proprietary code with full access to the system.


Apparently some motherboard bioses have an option to disable PSP


Now, I'm just cynical, but how trustworthy is a "Blackbox Backdoor: On/Off" switch, really? I didn't look much into it but Win8/10 also came with options to "disable telemetry" and it seems that was mostly placebo, to encourage adoption.

Like if the feds come and install a blackbox on your car, tell you it's a GPS tracker and your car will stop working if you tamper with it but they give you a handy dashboard button that they pinky swear disables it. Would you buy it? I'd still use the car, I got no other options but I'd file it as the agent having lost a bet or something.



Can't these backdoor-systems be used for improving security ? It's a system that runs beneath your system, it would be the ideal place to install a firewall and other kinds of security systems.

Why is the goal to get rid of this stuff instead of repurposing it?


The way towards "repurposing" such a processor would need a lot of reverse-engineering and even if someone managed to execute arbitrary code on it, who is to know how backdoors might still be activated e.g. by signed networking request. IMHO the best chance for any programming and eventual backdoor mitigation on such coprocessors would be a series of major leaks from a CPU vendor.

Learn cobol, work for FBI to maintain their servers for $150k, profit


You're not a real programmer unless you built every single circuit in the CPU by yourself, mined or foraged the materials by yourself and generated your own electricity to make it function


senpai, is it actually possible to build your own physical CPU? I'm talking about virtual ones that are simulated inside your computer, I mean actual ones that you can build with your hand


The most affordable option would be https://themosisservice.com/ offering circuit manufacturing with old tooling for about $25,000.


>realize that computers are more than just dealing with some abstraction that someone or some company wrote for their own convenience years ago
I really don't see the logic here. Even if this caused some practical difference, it would still be an abstraction, since the actual fundamental parts of the computer are electrical signals, not Boolean gates.


Is it the end of the Internet?
We are currently in an accelerating global crisis beyond what existed on October 11, 2020 what with the still ongoing pandemic, global energy crisis, and now global supply chain collapse and subsequent declaration of the Second Cold War by the CIA
Now let’s look at the internet
>Consolidated into a few massive websites
>Entire oceans of data collected about the populace
>Increasing woke censorship across the entire web
>Endless bot farms replacing human programmers and moderators
>Small off-shoot competitors keep arising that only exist to compete with the currently reigning sites
>Big sites all vulnerable to crashes and data leaks on their own, so definitely vulnerable to hacking and state interference
<Coronal mass ejection will likely happen by end of the decade
It’s over for Web 2.0 and I’m glad, fuck Reddit, fuck Twitter, fuck Facebook, fuck Google, fuck 4Chan, and FUCK THE CIA

>the only things that are holding up the major tech monopolies is their monopolies in intellectual property
The IP that helps them be monopolies is not patents, it's secrets, NDA and trademarks. Alt-tech platforms can do everything big tech can, but they don't have the userbase and branding that big tech has. That's why they're monopolies.

There is no way out of this. You can't escape because the normies will not change to decentralized alternatives if their friends and favorite brands aren't there.


>All while the mainstream big platforms retain most of the users' "main" profiles still and benefit from having easy "interoperability" with these social media "startups", so as to not miss on any of the data. A sort of controlled opposition. Like brands.
>Google, Facebook, Microsoft, Coinbase etc
They created a long time ago VC funds, and funnel there a lot of money.
It means they're investing in \ buying \ supporting "startups" (buying shares and voting power in these new companies). Shares = Control = Power.

The Web died a long time ago.



>There is no way out of this. You can't escape because the normies will not change to decentralized alternatives if their friends and favorite brands aren't there.
it's worth underscoring that in the case of friends, this isn't even a negative thing. it's a result of people having actual use cases for the technology (communicating with friends) rather than using it for the sake of using it.

what tech companies really exploit is network effects, which essentially makes a communication network like that a natural monopoly. it's a regulatory problem which, like landlordism and other parts of capitalism which are 'bad' even in a capitalist framework, capitalism is unlikely to ever resolve. but it's worth remembering that the blame lies not with the users, but with the system. the guy who won't move from facebook to opensourcebook (now with 15 users!) is no only marginally complicit in his exploitation than the renter stuck handing over money to a landlord in exchange for no longer living with their parents in a rural backwater.

All government services will stop using Windows in the next three years.

If more and more made-in-China PCs are being produced and they also follow suit, could that mean Linux taking over the world by 2030? Ultra based.

the government has been cracking down on it. a big problem is that western companies don't bother filing copyright suits in their jurisdiction cuz scary PRC, so nothing can even happen about it in the first place

Is investing in bitcoin or crypto worth it in 2021? I thought it would stagnate by now but there has been a lot of growth at the beginning of the year, if i remember correctly. I was thinking about putting a chunk of money on my wallet and letting it snowball until it grows a couple of times so that buying an apartment will be easier for me. Based or cringe idea?


Not /tech/, take it to >>>/hobby/ or >>>/siberia/


After Charlottesville, GoDaddy and Cloudflare dropped the Daily Stormer. They took 6 months to find a host afterwards(at dailystormer.name). And it wasn't just registrars and TLDs that were dropping them, but other services you wouldn't even think of also, from Airbnb to Uber to dating services to all of social media (including FaceBook, Twitter and YouTube), to payment processors like PayPal and all the major ones like MasterCard, Visa, Discover, and Amex, even the most major Bitcoin retailer Coinbase, and so on. What was most surprising to me was that Cloud flare rejected them, given Matthew Prince's rather libertarian views. This is something he has never done up until that point. They instead opted for BitMitigate. After Stormfront went down, they took it to court and won, however in the meantime Stormfront users configured localhost in their hosts file to access it. So instead of asking the internet where 'www.example.com' is, you can write the IP address in your hosts file and it will just use that information. This worked, but wasn't very practical as only people who have the ip can find and connect to it that way.

The internet is more delicate than most people would like to admit. All levels of internet, ranging from VPS servers (DigitalOcean and Linode both censor offensive content), to IP addresses and ASN numbers (there are only five companies that issue these in the entire world, with ARIN being the American one, and if they say you can’t get any internet resources, you’re fucked), to ISPs (your area has a limited number of available ISPs, and they are private companies which can terminate your service at any time for any reason or no reason. ColoCrossing in Buffalo physically unplugged Null’s servers in 2019 for hosting Kiwi Farms and Encyclopedia Dramatica), to peers (when data traverses the Internet most of its route is done through third party networks, not your upstream directly. If your content is offensive enough that peers start refusing to deliver content to or from your IPs, you can essentially be cut out from the world wide web. NTT refuses to peer with any company that peers with Null’s subnet, for instance), to domain names (this requires the blessing of two more companies: The registrar which leases the domain to the customer, and the Network Information Center (NIC) which owns the top-level domain. As an example: ZeroHedge uses EasyDNS as its registrar, and all .COM domains are controlled by Verisign. Getting permissiPost too long. Click here to view the full text.

the question here is of infrastructure, and how much the internet continues to be centered on it despite lolbertarian delusions of decentralization or whatever
the internet really still runs on corporations (the "backbone") and the labour that they provide to keep that "backbone" running, and you need equally scalable services to survive over that "backbone" especially under capitalism


Zeronet is immune to DDOSing and deplatforming.


Thats a pretty good summary of the issue of censorship and the centralization of internet infrastructure and resources. What can I say. I'm aware of all these issues. I dont think my developer peers are aware nor do they really care.


Worst case scenario is that somebody finds a way to break the internet, a fatal design flaw that can't be fixed or compensated.
That would force us back to square one, and we would have to rebuild the internet from scratch, with a new architecture that does not have this weakness. Even if it is so bad that we're forced to rewire the planet a second time, we're just going to do that. People have been building information systems for millennia. When ever you build a system there's going to be those who try to disrupt and break it, when they succeed people will learn from it and rebuild in a more robust way.

Seems like you are correct, since content like a webpage is tied to an encryption key, and not a networking resource.

So, if one of the weaknesses of our surveillance state is that there have to be people to sift through information, is it possible to flood info to the point where the effectiveness of the eye in the sky is diminished?

surprised this isn't already happening given how big of a problem spam phone calls have been for a while.

Please stop.


>make bots that spam bomb threats and shit constantly all over the internet
>no longer possible to know what's real or fake due to sheer volume
there is no good way to get accurate feedback information, and that makes it too hard to configure or optimize the bots.

>surprised this isn't already happening given how big of a problem spam phone calls have been for a while.

because the system can learn and adapt. Exploits are not just used as soon as somebody figures it out, they are hoarded, to be used with strategic timing.
Higher level strategic considerations include combining exploits in a way that makes it harder to detect or harder to adapt too.


People are doing that, it's called swatting. https://en.wikipedia.org/wiki/Swatting
>they either waste their time (and are potentially demoralized also) or so they become desensitized or stop giving a shit about certain patterns.
or 3. make the state target and harass our enemies. Get all the fash swatted every day.

This mother fucking company. I need to use some of their software like photoshop and illustrator but I can't play a damn monthly fee for their creative cloud shit. Any anons know how one might gain access to these programs without a blood sucking subscription?

>I need to use some of their software like photoshop and illustrator
Is there a specific reason as to why?
is something preventing you from using other software ?
does it really have to be exactly that software specifically ?

You could use Inkscape instead of Illustrator for vector graphics

You could use gimp instead of Photoshop or krita if you need more art related features

all these suggestions are free and open source software and they have many plugins that you can add for increased functionality.


Krita's the only decent one out of those three, they are run by the KDE people who are more open to listening to user feedback and continually add new features similar to the team at Blender. There are still lots of edge cases where CSPaint is more convenient to work with though, and it still feels like beta software. GIMP is run by the stubborn Gnome people who refuse to entertain the idea of considering any user feedback regarding UI or features, and Inkscape has only been in maintenance mode and hasn't had feature update for over a decade.


Suggest better alternatives that are also open source.
If you use programs that require a lot of learning investment, and you use proprietary software, the vendor is holding your learning investment hostage, and you are likely to have your skills randomly depreciated.

At the moment image manipulation editors are in a dry spell, the next step is to have object recognition and high level object manipulation, but in order to make that work fast and reliable, computers need to have something like tensor flow microprocessor cores and cameras need to have depth sensors that embed depth information into images.

The proprietary image editors are trying to avoid building robust object recognition like what i described by using large reference databases instead, that is a very foolish attempt at cataloguing infinity. And free software devs have their hands tied because they have to wait for consumer hardware to catch up, or open-hardware like RiskV mature enough to be accessible.


Try out Affinity if you're deadset on purchasing your software, they've got equivalent programs for most of the big stuff Adobe offers and it's a one time purchase as opposed to being monthly. They usually have sales that go on throughout the year, so you could just pirate it to familiarize yourself and see if you like it then buy it on sale. Think I got Affinity Publisher for about $30 when it was on sale last time and its been working well for my hobby projects so far, I've heard generally good things about their Photoshop/Illustrator equivalents.


They released Inkscape 1.0 last year and Inkscape 1.1 this year… It's not dead they are adding new features.
