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.

About fake social media accounts Anonymous 08/09/2017 (Wed) 17:44:15 [Preview] No. 10645 [Reply] [Last 50 Posts]
Should you not use any social media or use a faked, sanitized social media accounts?

I ask this question as I look at these new predictive algorithm. They analyse your facebook account, and gives some score to the police, to help them take a decision. There is plenty of different methods, and different means using that. Social media analysis is pretty much widespread.

I personaly don't use any social media, even though I have to say that I used them a little bit when I was younger (I quickly removed them though, nothing more than 2/3 years).

The problem with these kind of algorithm, or simple human verification (because it's pretty much automatic today to go verify your social media account, even in case of getting a job), is that it's gonna automatically mark you as suspect, since just a few don't use them.

So what do you think, should you try to fake out an account, with the risk of actually giving too much even though you try to fake it out (or if you use a bot, to be easely spotted), or should you simply go full boycott?
Soon, we'll be forced to pay with our smartphone, and so use a recent one with the app who allows you to pay. Now, there are people not getting hired because they don't have any social media account... I'm mostly afraid of the latter.


PS: Maybe is it too much effort, since your ISP by looking at the keywords you enter in the search engine, can know everything about you... I don't trust https.
I'm more and more afraid that without an enormous effort from your part, and huge technical capabilities, you can't do shit.

>(because it's pretty much automatic today to go verify your social media account, even in case of getting a job)
>there are people not getting hired because they don't have any social media account

This is a myth that has been going around for years. Unless you're applying for a job that involves social media, like being the social media coordinator or PR person for a company, most companies aren't going to give a shit about your Facegram and Instatweet accounts, and aren't going to check.

In many larger organizations, HR is explicitly prohibited from searching for the social media accounts of applicants, because it could be a source of information on the applicant like race, marital status, etc. and the company doesn't want to be accused of (and sued for) not hiring on the basis of having known this about the candidate.

I boycott social media, except for a bogus Twitter account that I use to follow certain accounts I like to keep track of. I work in a public-facing role, so there's already basic information about me (name, a photo, work phone and email) on the company's website, so if I thought it were necessary to have social media accounts, I would make them with no more information than is already available online.

I don't see any point in doing that, though, and to be honest, if someone looking to hire you is such a turbo-normie that they care if you have social media accounts, they're probably going to be freaked out if you don't have lots of friends and activity on your account.

>Maybe is it too much effort, since your ISP by looking at the keywords you enter in the search engine, can know everything about you... I don't trust https.

There's no evidence that ISPs can compromise https without using a very obvious MITM attack that would require a user to manually accept a bogus cert.

I used to have multiple facebook accounts and one of them was just for normies. All the people I didn't know well got added to that one and in fact I tried to get it up to a few hundred people so I could point to it and look normal and fairly popular if I ever needed to, or for networking, and I made it less private overall.

My other account was for people I trusted. That was before I just decided to get rid of all social media.

The less people using this system of data mining the better. That way they will be the outcasts. The problem here is with their bots. A lot of bots account for youtube views for followers etc. That may be the only lucritive thing about making fake social media accounts. Using bots for profit. That is still validating social media though.

You're right on that. Tox was initiated on /g/ shortly after Snowden disclosures. It was made to be foss, distributed (so no servers are used) and provide strong encryption but anonymity hadn't been thought. It was added sometime after the project begun though. https://github.com/irungentoo/toxcore/blob/522f90fee138087db660dccc08413c53f388f604/docs/Prevent_Tracking.txt

If he posted this in 2004 that would actually make Mr. Michael McAllister 27 years old at the current time.
The average age for passing the bar is 27 and the pass rate is 66% in New York State.
Based on that I highly doubt that he's passed the bar exam. You're looking for a Law Student approximately 27-31 years of age, a white male. He might be attending Columbia Law School. Here are some other possible options:

its the chan cycle like kali yuga.

refugee from 4chan to 8chan to diaspora now i guess. i've been trying all of the chans i know but they have small userbases compared to 4chan and 8chan. i've heard good things about nntpchan but haven't tried it. and blazechan has innovative features.

8/tech/ users are 95%+ larpers who never code. i remember back 2014 - 2015 it was completely different. there were groups legitimately trying to help anons gitgud but nothing came of it.

it's sad and very frustrating the cycle of the chans.

i used both /pol/ and /tech/ on 8chan. 2014 there were a lot of crossposters. but they coded and didn't use the board for shitposting. there was an effort to help interested anons on /pol/ gitgud with self-improvement threads. blame it on the mods when they started banning self-improvement threads they drove out core users leaving only idiots who spread to and degrade board quality on all boards. when new users come to /pol/ they see these idiots and learn to act like them.

8/prog/ maybe is still worth something.

we should start monthly library threads here (or, tri-monthly since the board is slow). work with a new library every month and compete to see who comes up with the best shit. 8/tech/ did this early 2015 and then it died out. but they were some of the threads i enjoyed most. we should restart it. be the change you want to see.

there's always the issue of good content vs active posters. IMO the reason why a lot of boards decline in quality is that a certain amount of activity is needed for people to be engaged and without engaged posters a board is easily taken over. A high quality board can die due to lack of content and then easily have its skin worn by nu poasters

Poettering (a Red Hat employee) is not the source of the problem in the modern Linux ecosystem. Red Hat is the problem. Red Hat has almost complete control over freedesktop.org (xorg, DRI, cairo, mesa, wayland, systemd, dbus, PulseAudio, Gstreamer, xft) and GNOME (this includes all its applications and GTK+) and has a massive influence over the Linux Foundation and many GNU projects. Red Hat is a for-profit corporation so any action they take will only be for their own benefit and NOT yours. Regardless of whether their software is "FOSS" or not, they've slowly been redesigning the core design of Linux so that they could restrict your usage of it to their products, making you dependent on them. GNU/Linux should be renamed Red Hat OS, as it's essentially impossible to escape their tentacles on it.
