Based on the details you have provided us with, this website seems like it would most likely be shit. Also, the fact that you make posts and get cryptocurrencies for your posts highly implies that accounts are required which would be useful for datamining and is yet another security concern.

Part 2

Just checked out their website and did a bit of digging, it appears the company was made by two individuals known as Dan Larimer and Ned Scott. Apparently, they created this website because:
>“Dan and I are similar in that we are motivated by the idea that we can improve the way of life for others. The state of Internet communities is imperfect – among the sometimes great content, there are also trolls, less than helpful comments and poor dialogue – so there was definitely a problem to solve there in the context of social media."

I also see Reddit being mentioned frequently, so I believe it is highly likely that the CEO is a redditor or made this website with redditors in mind. The website did get its idea from reddit (Make posts, get upvoted, get money).

The website itself is also shitty, riddled with unnecessary javascript and has that faggy web 2.0 look that appeals specifically to millenials and takes up CPU power.

The one side I didn't look into that much was the currency they give users, it appears to be their own currency that is according to them, worth around $1 USD.

I don't know whether they do, but requiring an account isn't a security concern per se. It might be an anonymity or privacy concern depending on a number of factors (including a user's opsec practices).

Security, privacy, and anonymity are not all the same thing. Please learn the difference.

I use absolutely no accounts whatsoever, I have never needed to use them, and when I do need an account, I make a quick throwaway one to complete the necessary tasks at hand. Assuming I have other accounts on the internet, if I was incompetent or had a bad memory and used a single password for every account, my account could be used against me. An account also allows the website and governments know when I frequented a website, how long I was on said website, how many times I have frequented said website, etc. Making an account on a website almost always forces the creator to accept the terms of service and privacy policy, and well made TOS or privacy policies can fuck you in the ass with very vague wordings...

>This is the kind of memery-as-critique that I'd expect from 8/tech/. I thought we could do better. My bad.
Unnecessary javascript to enhance the appearance of the website which causes my already somewhat slow computer to run even slower and waste my time as well as my resources. It is evident the website got its idea from reddit due the high amount of times the CEO mentions reddit, how the website refers to positive feedback as "upvotes", the javascript to enhance the appearance which obviously isn't there to appeal to competent technology users and programmers.

You can't block an entire domain in /etc/hosts, unless you have an entry for every single host, but that's not doable for something the scope of google. But you can block all of * if you run a local DNS server. For example, I have this entry in /var/unbound/etc/unbound.conf, since I don't want to have anything to do with fb ever:
local-zone: "" refuse
I would do the same with google exept that I actually use their gmail service, and at one point they started to require you to "login to your google account" instead of just loging into the domain.
They also have some other domains like,, and so forth. Probably best to get your browser to log everything and then check what other stuff needs blocking.
Also the hosts file from is useful but doesn't cover everything.

My apologies, I don't know why I thought you were running windows. You should be able to do the same conceptual thing though - watch outbound DNS lookups - with tcpdump or whatever packet capturing utility you've got on your OS. I'll second 10862 - run a local DNS server.

Don't be a conclusion-jumping condescending douche. You've actually inspected the source code of a miniscule fraction of a percent of everything you are running right now, and if you think having source covers all your security bases, you're doing security wrong and relying on an unrealistic world view. Take inventory of all the proprietary tech and embedded systems you actually deal with on a daily basis. I'm pretty sure you aren't inspecting the source code running the ABS of nearby cars before crossing the street.

In the movie she is not Motoko in the beginning. She has a makeup that makes her eyes look slightly asiatic.
but movie is shit still, they didn't find actual japs to play confirmed japs like Togusa and Batou, the cgi is really awful, the didn't bother with creating a new city, they just slapped some olograms on HK skyline, and fat jewess is too old to play such role (there are some scenes without cgi where you can see her fat belly), but she is recognizable worldwide and I really doubt there are japanese actresses with enough skill and english knowledge (lipsync dubbing is not a common practice in hollywood).

I was looking at Ubuntu Budgie but there was not UI scaling option. Unity seems to have the best scaling and the GUI is all over the place. Icons are too small so I make them bigger but the text underneath is still tiny. Modal dialogs scale oddly. I compare this to running Ubuntu on my desktop(1080p).

Mozilla To Build New Browsers That Conform To Internet Censorship

In November of 1737, decades before America officially declared its independence from the king of England, a young Benjamin Franklin published an essay in The Pennsylvania Gazette entitled, “On Freedom of Speech and the Press.” In it, Franklin wrote, “Freedom of speech is a principal pillar of a free government; when this support is taken away, the Constitution of a free society is dissolved, and tyranny is erected on its ruins.” Franklin went on to write, “An evil magistrate entrusted with power to punish for words, would be armed with a weapon the most destructive and terrible.”

Although this was written in an article published more than two and a half centuries ago, Franklin’s words are quite possibly more relevant today than they ever have been. Indeed, there is an ongoing effort by the progressive left and extremists such as George Soros to silence speech that doesn’t align with the liberal agenda. This effort to effectively gut the First Amendment is taking place virtually everywhere you look, from the mainstream media, to Hollywood, to college campuses, and perhaps most frequently, across the Internet.

Recently, the popular Internet web browser Mozilla Firefox announced that it plans on joining the fight against what it considers to be “fake news,” a term that to leftists means nothing more than news that is written by conservatives. Mozilla said that it was “investing in people, programs and projects” in an effort to “disrupt misinformation online.”

The first question that every constitutionalist and liberty-loving American should be asking is as follows: How does Mozilla define “fake news?” Are they only talking about suppressing radical websites such as sites run by white supremacists, or are they talking about any news that comes from conservatives? At the very least, it should worry you that companies like Mozilla are often reluctant to thoroughly define “fake news” – it is highly unlikely that this is unintentional.

Furthermore, what exactly gives Mozilla the right or the authority to determine what is misinformation and what is not? The United States Constitution is the law of the land, and the freedom of speech is an inalienable right from God. The fact that Mozilla thinks it has sweeping authority to select which speech is censored and which speech is not runs contrary to everything that America was founded upon.

With the assault on independent media getting increasingly aggressive, many Internet bloggers and website owners are desperately looking for ways they can continue voicing their opinions without being harassed, suppressed or silenced. If you are one of these people, you may want to consider using “Brave,” a relatively new web browser founded by former Mozilla CEO Brendan Eich.

On its website, Brave states that its goal is “to transform the online ad ecosystem with micropayments and a new revenue-sharing solution to give users and publishers a better deal, where fast, safe browsing is the path to a brighter future for the open web.”

>Look at it this way: you have to groups (racist supremacists and 'politically correct' mentally disturbed nutjobs) fighting in the streets, punching people, driving people over with cars, tackling people and beating one another up[..].
It seems that those are largely the same kind of people, they have just been conveniently divided by the governent-industrial-complex along some arbitrary, one-dimensional axis so that those who are discontent with how things fight each other instead of uniting and working against those with actual power. It's classic divide & conquer like feminsm and all that nonsense. Google has recently been displacing anything that disagrees with WashPost et al., doesnt matter if they are "left" or "right".

I have also long suspected that at least some of the liberal SJWs or white spremacists (or terrorists for that matter) are sock puppets. The Brendan Eich spectacle comes to mind, /pol/ was chimping out about "degenerates" while the SJWs where throwing a tantrum about "hompophobia". This is how the media framed it. I never saw Eich's definitve stance against the implementation of DRM in Firefox mentioned and how him becoming the CEO put that hope on ice, or how much money Hollywood was losing by missing out on customers due to having to use the instranparent NPAPI plugins for DRM. Or how his replacement, the former CMO and former CEO of a venture capital start-up, put DRM which is antithetical to Moziila's manifesto on the fast track. SJWs are incompetent, it wouldn't surprise me if Hollywood and friends didn't go out of their way to dig up dirt on Eich, anonmously tip of some "influencers" and then orchestrate the hole defamation campaign to subsequently install their corporate-friendly tyrant.

Ultimately though it matters little if the governent-industrial-complex is behind the boogeymen or merely being opportunistic, the resulting shift of power from the bottom to the top is the same.

>Not in all cases. Friendships that were weak in the first place result in this, but robbers with a deep history are highly unlikely to do this, and they can very easily split the profits.

That's false. I was talking about official statistics. I'm not talking about movies.
In the reality, everyone want to fuck everyone, at a low robbery level, and at the high level. "High intellectuals" only make the scam better engineered, with higher reward, but the spirit is the same. In fact, it's worste and worste with time. That's true that in the past, the stealer were organised in corporation, the ancestor of mafia, but the hierarchy was and is still organised upon fear, money and blackmail, and still everyone wanted to fuck everyone. The method got worste with time, and their power is greater today than ever.
A secret service is a mafia. A government is a mafia. But that's just some coggs, and a religion/ideology is CERTAINLY not enough to maintain anything here.

You should ask yourself why the real top don't care about money, and why they sacrify children, and do blood ritual.

You said you were searching about who control these big monopoly. Well, no one can know, since there is the shareolder secrecy. Maybe an unique team of people possess everything, even concurrent societies. The CEO is important, but it's not the top. Who knows.

You simply verify it with wireshark, by checking if any package is unencrypted. But yeah, you have some things to desactivate in firefox. Or do the right thing, and stop using firefox, if the recent join of mozilla to the hunt of the alternative news isn't enough for you to move out.

For openvpn to work with unbound, you have to add "push "dhcp-option DNS"" in the config file on server side. (/etc/openvpn/server.conf)

Moreover, It's not gonna be good with time, but I only use ipv4. I had too much trouble setting up openvpn for ipv6. I heard that some VPN you buy are doing the same, but since you don't have specified your system to use only ipv4, you're leaking every ipv6 connexion you're doing...
So going the job yourself definitively is useful.

>won't disabling webgl and DNS prefetching in your browser help prevent DNS leaks while using a VPN?

I don't see why webgl would be a problem, and DNS prefetching would only be a concern if the browser uses its own DNS servers in order to provide that functionality. That wouldn't surprise me, though: I could see Google, for example, hardcoding and as the servers that would be used for prefetch in Chrom(e/ium).

The bigger concern is WebRTC. Make sure that's disabled. It's easy to deanonymize you if you have WebRTC enabled.

So Jim (an ex-Gamer Gay fag and an old /pol/ sweetheart) made a new video recently, and in the face of the centralized clearnet's censorship schemes becoming ever expanded he has made the suggestion of going MAD against the clearnet giants. As some have pointed out though, this is a dangerous gambit due to Google Fiber expanding very quickly and them having the money to bide their time while they expand. Not just that but handing the internet to the ISPs is a bad idea since ISPs are much more HEAVILY centralized than web services and communities.

However I want to hear endchan's opinion on the matter, is this a feasible strategy, or did Jim as the vid's thumbnail/graphics suggests, drink a few too many vodka bottles in a stupor of depression?

Only time posts should be deleted is if they are spam posts, posts containing illegal content to fuck us over, etc. Even shitty posts should be allowed to stay, just hide them and have a button to reveal them. This concept exists on a website known as Meguca and posts aren't truly deleted, they are hidden and anyone can open them by pressing a button.

This isn't related to the discussion (possibly a little...), but I have an interesting hobby of mine when it comes to observation. I love to walk around in the wilderness (Wilderness being areas free of man-made objects or land that naturally occurs) and look for interesting animals or insects that I haven't seen before. I draw detailed pictures of the specimen and pursue it for a few hours to see how it acts and how it works. It is highly similar to Zoology and is much more effective than reading a book as actually observing real life phenomena and simulating your senses forms stronger and longer lasting memories.

Geology is also pretty fun, especially in desert areas (New mexico, Arizona, etc.)

It's really not too hard to farady cage your data, and you don't have to farady cage your whole computer. What I do is store all my important media/data offline in both DVD and flashdrive mediums, and faraday cage those backups. You can buy static-proof / RF-proof "faraday bags" online for pretty cheap, sometimes you need to double-nestle them to absolutely assure proper EMP prevention.

I also have an old big Creamtex container from a farm that acts as a proper faraday cage (yes, I've tested it out with radios and cell phones, they get no reception when being closed in the container). That I store a perfectly good laptop inside with Linux OS already installed, along with a bunch of other flashdrives and storage mediums to keep them protected.

If there were an EMP, sure my regular computer would be toast, but I'd have a backup laptop & mouse with all my important files double-nestled inside faraday baggies.

Another thing preppers look into is actually surviving an EMP, which your faraday cages do NOT provide a solution for. Extra food, extra water / filtration system, extra guns/ammo/mags/rem oil, extra matches/lighters, an alternative source of energy (must be EMP resistant), extra toilet paper / paper towels, extra sanitation products like soap and hand sanitizers, extra toothbrushes/toothpicks/floss... all the essentials would be nearly impossible to get in a crisis scenario such as an EMP event. Where you could get them, they would be heavily rationed and scarce too. After an EMP, there would be no mass transportion so stores would be dried out of supplies within days.

Why five laptops you may ask? Well, that is if one of them breaks, I can move to another laptop and use that one instead, and if all of my laptops break, I can find the broken parts and use working parts from another to fix it.

you can easily spread images that contain stenographically embedded lists or files, even html/mhtml/maff/arc or plain old 7z/zip/tar.gz

FLOSS and licensing Anonymous 07/31/2017 (Mon) 16:22:43 [Preview] No. 10510 [Reply]
Hello /tech/,

I'm not so familiar with software licenses so I started reading about the subject. At one point the question 'How does one profit from floss software?' popped in my head and these are some articles I came upon (quite outdated, but they still have a point). So GPL prevents companies from making proprietary software with your piece of software. BSD, on the other hand, does not (that's the case with Apple's kernel). Turns out the only way a company can profit from GPL license is by donations, offering support, teaching or dual licensing. Dual licensing seems like the most used option.

>But there is a net effect on software development. Who makes money off GPL code? We go back to Novell and Red Hat, who test and package this software. And we see a trend–GPL code helps software testers make money. It helps QA people. It helps the people who answer the support phones. It helps everybody except software developers. Oh, maybe Google will pay them a salary as a goodwill gesture. But it’s really, really hard to make money from developing FOSS. You can make money supporting it. You can make money testing it. But no money developing it.

So my question is - does free software actually benefit the developer?

>The GPL makes it harder to make money.

That seems a little like saying that you're going to be hungrier because mom added a side of broccoli to dinner. The existence of GPL software adds to the options that you have if you are developing software and want to make money. I don't think it makes anything harder.

Perhaps the core idea there is that the GPL doesn't make it as easy to make money as a license that allows you to take someone's code and resell it as your own does. I agree with that. For example, the zlib license is easier to make money with than the GPL license because you can use it in a commercial product and not release the source. That doesn't seem like a reason for me to complain about GPL software that benefits me and sometimes does what I want in other ways though.

What's the bottom line beef here anyway? If you are opposed to GPL licensed code and, like me, don't include in your development projects when you don't want to release under GPL, then don't use it. Problem solved. I use it when it makes sense and I want to give code that keeps on giving away and I don't use it when it doesn't.

If making FLOSS software meant helping actual competent and interesting programmers and computer engineers/scientists, then I would disregard money for the most part. I don't believe individuals/groups make FLOSS software for profits in the first place, if they wanted profits, it would be more efficient to write proprietary closed-source software for large companies or massive groups of computer users.

There are plenty of benefits of being a FLOSS software developer:
>You are more likely to be recognized by FLOSS communities which tend to be populated with highly intelligent and competent individuals.
>You are helping fight proprietary, non-free, and closed-source software by distributing and creating FLOSS software.
>You can very easily use your own software to your advantage and have an extra highly strong layer of security by using your own software that wrote.
>Your software has a higher chance of being used in OS distributions and software bundles (Look at Chrome OS). If you don't like your software being used against your will, maybe it shouldn't be free and open-source in the first place.
>You are seen as a trustworthy person and will be useful in the fight against surveillance and unwanted data-collection.

It also seems to be a misconception that once can only program either FLOSS or proprietary software and not both. You can make some of your software FLOSS and other software proprietary.

- Good security practices (no unnecessary permissions)
- Uses libsodium, a modern and stable crypto lib with well revised code. Uses AES-256.
- Leaks less metadata on pubkey
- Smaller pubkey.

I think they also have added pledge(2) to the reop ports on openbsd.

- No support for GUI tools, like for Thunderbird
- No support anywhere, really
- It's not maintained anymore (not exactly a problem, because the code is considered "done" by the author. No bugs found)

It's not. It's abandonware that nobody gives a shit about. Nobody uses the public-key functionality of reop, and the AES-256 functionality is redundant. There are plenty of options for AES-256 encryption on common operating systems that are either already available, or can be readily installed without having to compile from scratch (unlike reop).

The one person on this board (and on the planet) shilling reop was challenged to demonstrate the superiority of reop's AES-256 functionality against other implementations by referencing the relevant source code, but he failed to do so.

There's nothing in that list about the gnupg implementation of AES-256 file encryption or the reop implementation of AES-256 file encryption.

The one person on this board (and on the planet) shilling reop was challenged to demonstrate the superiority of reop's AES-256 functionality against other implementations by referencing the relevant source code, but he failed to do so. Again.

If you are having difficulty locating the source code in question, I would be happy to provide you with a link. Just say the word!

Also, although it doesn't matter, because that link demonstrates absolutely nothing that's relevant to this discussion, I would note that that list goes back 11 years and has only one critical (remote) bug.

Hello my good fellows!

It is evident that the majority of mainstream software programs are shit, and while audits and the creators of a specific software program can tell one much about the quality of said software, audits can be fabricated and the user should look at the program itself instead of looking at who made it and where it came from. If more individuals studied computer engineering/science and programming and were able to audit programs, we would become stronger, and one could rest assured that their computer was tested to perfection. I have begun to notice that a major problem with auditing code is the fact that some software programs are massive and require teams to finish in a practical amount of time (Or one individual with ultimate dedication...), and this can be fixed by advocating for single purpose programs with lean code and minimal features with room for the user to build and add to it. Computers are amazing machines, and every individual with a laptop and a great mind can achieve amazing feats! One could build a self driving car with the power of programming and advanced mathematics, one can program a self-learning AI that they can interact with, one can program drones or small satellites to take pictures of the earth and predict weather patterns, and the list goes on and on.
I am here to encourage you to begin making your own single purpose programs by yourself or with close friends and a passion to teach others about programming and auditing simple software programs. I don't believe there is a government plan to keep us all down and steal our data to destroy us, but your information is worth money, and data mining allows companies to look at the big picture and advertise products.

Free(Possibly) and open source software with a single defined purpose made as minimal as possible with space to allow for building onto it and improving it.

Extremely intelligent and dedicated trolls are funny as fuck and actually achieve what they desire and do it with a passion, the massive majority of trolls are idiots who think that wasting someones time and pissing them off for a few minutes is trolling.

Based on my observations, it seems that the majority of "idiots" are incapable of learning or becoming more intelligent in life, those who appeared to be idiots and later became highly intelligent may have never been idiots in the first place, just victims to peer influence and a blurry outlook on life and their purpose. I never understand why people try so very hard to prove themselves correct when their arguments are easily refuted with better alternatives to their recommendations (Better at performing the original softwares job). Is it a fear of being proven wrong? Is it egotism at work not allowing the individual to accept defeat and the fact that they were wrong for once? Is it a sad attempt at trolling that was flipped to target the original troll?

A large part of intelligence and "evolving" or becoming "enlightened" is to not allow egoism to consume you and striving to remain open minded (There are no levels of open-mindedness, you either are or aren't). People need to throw out their old beliefs if new better ones are acknowledged, even if an individual dedicated large amounts of mental power and time into the old beliefs.

I openly welcome any individuals on here to refute the points I have made in this post and to correct me if I have made any incorrect or false claims.

GNUPG has just released a fix for a dangerous side-channel attack that could expose your private key, a leak of NASDAQ test data was picked up by real news organizations and caused a bit of a panic & the fascinating story of a security researched who managed to take over all .io domains with a little sleuthing and a few domain registrations.

This is pretty cool. Wish I had e a program that could help me print things that can only be decoded with another transparent layer.

Hey. Can you make it work with multiple images?

Like. Aline it to the left. Get one logo. Aline it 3/4s right get another?

Sure, it's just a simple equation. In the pictured image it's a mere (g.field) sum. To have multiple resulting plaintexts you would add another equation to the system.

Say A and B are the images, x and y the ciphertext and keystream (in F(2^n)), then the pictured example is just a trivial:

A = x + y

To also have B, you would add another constraint, say:

B = (x << t) + (y % 2^(n-t))

Where t is the offset for ("3/4 to the right").

Strictly speaking this would not exactly describe the pictured example, because there the displacement is not linear but 2-dimensional, but we can sidestep that by instead considering A(i) and B(i) (and x(i) and y(i)) for each "i" pixel row in the images.

If you keep adding constraints you might eventually make the system unsolvable, but for two offset images it's pretty much trivial.
