ARM Comrade 01/27/2020 (Mon) 22:18:36 No. 312 [Reply] [Last]
I am looking to purchase an ARM processor. My instinct I to just cave and go with a raspberry-pi, but, I have heard there are plenty of, better, alternatives to the raspberry. Can anyone point me in a good direction of arm related processors and the like? Would be helpful as I, basically, don't really know where to start. Pi's are cool but I don't have to choose one of those. Anything really. As long as it ia secure and runs smoothly.

I've been watching one consumer e-ink reader after another ship without true bistability for years, along with only a very thin trickle of underwhelming and recent flexible e-ink readers, meanwhile both technologies are vastly better represented in a number of OEM displays (especially much higher dot pitch) no retail device actually seems to ship with.

Does anyone here actually use this? Be honest. I feel like I miss out on a lot of stuff and can make a lot more friends if I decide to use this, but tinfoil autists on /g/ keep shilling against it. It has pretty much become the standard for communication in most online communities so it feels like you will be harmed more for not using it than otherwise, I guess that is how it goes for most big proprietary products these days.

>>3968 We use their servers I think, I might try and setup an instance but I don't have money lying around for a home server and we don't really have the budget as a group to buy tertiary things like that unless we really need them I think that it's so intolerant of poor connections due to the way it handles dropped packets or lag or something it cant seem to deal with user upload speed dropping below a certain threshold or suddenly spiking downwards anywhere near as well as discord can, audio and video quality are actually fine on bad connections but the stream gets so choppy on a poor connection you're getting still images and half sentences in hifi when it would be better for it to tank quality and maintain consistency
>>3930 yes, but treat it like any other compromised tool. I only use it to talk about non political shit same with any ""social media""
Everyone I know uses it and I can't exactly get them to move.
>>3931 >no more than your average social media site No, it's substantially worse. Most obviously, you can't even read-only access something posted in it without an account and an invite. If more sites start behaving similarly, that would completely kill the web. Allowing Discord to grow is irresponsible.
>>3930 No. I used to when I was younger. You aren't missing out on anything of value. It's all garbage. There is no serious discussion on Discord about anything.

Privacy general Comrade 05/08/2016 (Sun) 16:12:51 No. 2214 [Reply] [Last]
Comrades, we need a thread on privacy. Any decent activist should try ways of staying anonymous on the web and prevent being tracked by governments and corporations.

General tips

* Use free software as much as you can.

* Use GNU/Linux and keep it up-to-date, to be sure that you don't have unpatched security exploits

* Don't use Flash Player, use youtube-dl instead for watching streaming videos online

* Do not use Google, use DuckDuckGo or StartPage instead

* Use a password manager like Keepass or for GNU/Linux users keepassx. Create new passwords for every site that you visit and use a strong password as a master password. A tip for easy remembering of your master password is to use a sentence. "i fucking love cookies and tits!" with extra capital characters etc. is easier to remember than some random characters and long enough to prevent brute force attacks of any kind.

* Use the Tor Browser Bundle if you really want to stay anonymous.


* Go to Preferences -> History and set History to "Never remember history".

* See for additional tweaks: https://github.com/amq/firefox-debloat and https://vikingvpn.com/cybersecurity-wiki/browser-security/guide-hardening-mozilla-firefox-for-privacy-and-security


* Use uBlock Origin for preventing tracking etc. Bonus: use hard-mode to manually whitelist external domains on sites. Don't use uBlock but be sure to use uBlock Origin https://github.com/gorhill/uBlock/wiki/Blocking-mode:-hard-mode

* HTTPS Everywhere

* DecentralEyes: prevents CDN hosting from tracking you (Google for Jquery etc.)

* Self Destructing Cookies: only allow cookies that you choose to allow


* Encrypt your hard drive or home partition at least

* If you use GNU/Linux, you can try to restrict systemd or syslog from logging.

* Use a distribution which takes security seriously. Also, be sure that you don't install a lot of things outside the repository. It will cover most of your needs.

Real life tips

* Pay with cash if you can

Feel free to provide tips to each other comrades!

>>2214 >Use a password manager like Keepass is it alright if i use bitwarden? i like the easy sync across multiple devices
>>3958 If you're talking about their cloud offering then its enough to deal with reducing password reuse but because the database is stored on their server and is encrypted/decrypted via a webpage they control you should not expect any protection whatsoever from anyone with serious resources. If three letter agency wanted access to your passwords on a self controlled keepass database then they would have to either thoroughly compromise your computer (to the point nothing would help) or get the password via other means, for something like bitwarden they could potentially walk into the office with a subpoena and have them change the web page so it sends your password to the server and decrypts your db for them, since there is no warrant canary assume this has already occured.
>>3958 I'm using keepass and tbh I don't see the problem with just transferring the file around, its like 5kb, I've got into the habit of just copy/pasting it across my different machines when I update it on my main machine, it takes like 2 seconds to copy it to my phone and push it over waprinator or ssh to my laptop, if I needed to get it remotely for some reason I could just put the encrypted password file in a cloud repo or github or something and up the masterpass complexity/change the pass after downloading the file (I don't forsee ever needing this so I don't have an online backup of it, doesn't seem like the greatest idea even if a 30 character properly configed masterpassword should be virtually uncrackable) I think the slight hassle is worth the extra comfiness of knowing its not being passed around in a cloud server by some company somewhere, and the passwords don't need to change often, since they're so strong, and they all get changed at once since force change after a certain time is enabled for them

Hi /tech/ This might be an odd question but I just had this idea Q: Is there some way to collectively keep track of 'plans' made up by the collective in a given chat group? Say we're three in a group-chat, we decide to do x thing on y date a month from now - is there some application that's designed for this scenario? Wouldn't it basically have to be part of the chat-program to not pose a security risk? Have you ever used a chat program that has this function?

The Coding Interview Comrade 07/26/2020 (Sun) 17:34:10 No. 3641 [Reply] [Last]
What's up with the coding interview? You would think being a competent programmer would be enough to get a job but there's a whole industry out there specialized in preparing people for code interviews. It even has a Wikipedia page of its own. No other industry has a specific Wikipedia page for their job interviews. Why? What went wrong?
I once heard of an interview for an IT position that was intentionally very exhausting so that when the negotiation time came the interviewee would be exhausted and wouldn't ask for a high wage. I don't really have any experience with interviews, however i don't think that an interview in a small-medium company would be hard enough to require any special preparation. The fact that there exists so much stuff on programming interviews might be because there are a lot of jobs in that field, and that a lot of people without adequate education look for programming jobs, so the interviewer needs to know if the person actually knows what they need to know before they hire someone.
>>3641 >Why? What went wrong? Silicon Valley startup culture that leaked into normal tech companies. This doesn't exist in other technical fields (ex: mechanical/electrical engineering) because it would bee too complex to fit into a 45 minute interview. Took off in SV because the founders were all 23 year olds who didn't have experience in real software engineering so they just ask questions out of a coding competition or data structures/algorithms book instead. That and since a bunch of people without CS degrees are in the industry now they have to test the core CS knowledge that you would learn with a degree (DS/A). They want to hire self taught hipsters but also know they aren't pseuds. I personally don't think its a good strategy i would rather have someone do real work or show a project they made or something rather than solving algo problems on a whiteboard in 45 mins. You can imagine its the sort of process a nerdy white guy CS/math major from harvard would find interesting but anyone over 30 would probably just think is bullshit and a waste of time.
>>3651 >They want to hire self taught hipsters but also know they aren't pseuds I think there's a deeper underlying problem: Software "engineers" aren't actually engineers. Real engineers in other fields are certified similarly to lawyers, doctors, pilots, etc., complete with them (AND THEIR EMPLOYERS) being subject to legal liability for failure to meet standards of their field's accrediting body. Pretty much nothing like this exists for chodemonkeys, even college-edumacated "IT majors" and holders of "certifications" from Cisco, Microsoft, Oracle, etc. have no real assurance of even minimal competence: https://blog.codinghorror.com/why-cant-programmers-program/
>>4000 So your definition of an engineer is someone who received a specific certification and has "legal liabilities"? I guess Tesla wasn't a "real" engineer since he never received a degree or certification, he's obviously some electromonkey or something. Was Steve Wozniak also just some "electromonkey" and "chodemonkey" for designing the Apple I and Apple II without a degree, certification or being bound by legal liabilities?
>>4000 Also nice job citing a blog from 2007, before leetcode, topcoder, projecteuler, khanacademy, etc. etc. were a thing, before FAANG's corporate dominance and consolidation of the internet, before the 2007 financial crisis, before the first iPhone was released, your blog is prehistoric by the rapid pace of the changing IT world.

Designing transparent and secure election systems with computers Comrade 07/09/2020 (Thu) 23:00:09 No. 3173 [Reply] [Last]
Many countries around the world, after some initial experiments, have completely dumped the idea of running their election systems with computer hardware and returned to hand-counted paper ballots. One look at the cartoonish hodgepodge of election machines with a million security holes across the United States all making use of unauditable proprietary software and hardware and manufactured by private companies mired by a history of corruption and scandals. One look at all that would be enough to give any reasonable person pause to reconsider the entire idea of electronic voting. Is it possible to design an electronic voting/counting system that fulfills some basic expectations of security and transparency? I and many other computer security experts would argue that it is not and never will be due to some fundamental aspects of computers. But let's not let that spoil our fun. How would you design electronic voting systems to be secure and transparent? What would the hardware be like? What would the software be like?

>>3177 This work work fine too. A pseudonymous but verifiable cryptographic signature is a solved problem. Look into zero knowledge proofs as well: https://research.kudelskisecurity.com/2018/11/05/e-voting-crypto-protocols/
>>3197 >Its simply not feasible to have tons & tons of properly organised paper votes for things like workers councils making small decisions. Why not? It's being done right now.
The fundamental issue isn't that its an unsolveable problem, its that you still have to trust the organisation running the election more than you do for a paper ballot.

Centralization of the Internet; what to do about it and would decentralization come back in a socialist economy? Comrade 04/20/2020 (Mon) 21:22:16 No. 1287 [Reply] [Last]
Hey all, It is sort of eerie, back in the Web 1.0 days, (I know showing my age here) there were so many websites all created by ordinary people all expressing themselves. Now big corporations have barged in and so many people are now using these centralized websites and services without even knowing of any alternatives. Would such a decentralization and expression come back to the internet in a socialist world or would it be used for something different?

>>1305 There is a meshnet in my town and it's pretty cool, they use wireless equipment for connecting to each other. I haven't researched how much the equipment would cost but i'd guess that its somewhere in the hundreds for just a short link, but the subscription is dirt cheap and the speeds are very fast. Internet access isn't guaranteed though, there are some people within the network that share their internet connection. Meshnets should be way more popular and widespread than they currently are.

Both the 1-way consoomer "Web 1.0" and the monstrous JS hodgepodge of "Web 2.0" are perverse accidents of history. Note there was an attempt by the web's original authors to fight all this, and right the course of the web with semantic metadata: https://www.w3.org/2009/Talks/01-15-steven-website/ But it was scuppered by Google/Apple in the fight between W3C vs. WHATWG, resulting in the death of XHTML in favor of HTML5.
