A puzzle, just for fun.
Two friends, (a)lice and (b)ob are communicating through a channel encrypted with random numbers XOR'd together, like so:
keyA = randint(1024, 1024**2)
keyB = randint(1024, 1024**2)
msg = randint(1024, 1024**2)
You, an interloper, have watched all these communications, siphoning the packets as they went.
When alice sends a message to bob's mailbox, she does it like so:
mailBoxB = keyA^msg
Bob's mailbox receives the mail automatically, and applies his own key, sending it back to alice's mailbox:
mailBoxA = keyB^mailBoxB
Next, Alice's mailbox notices the message, and automatically removes her key and sends it back to bob's mailbox. All of this, the first message, the second, and the third, happens in milliseconds, the back and forth.
mailBoxB2 = mailBoxA^keyA
Finally, bob's mailbox removes his key, and deposits the now unencrypted message in his box, for him to read in the morning:
mailBoxBFinal = mailBoxB2^keyB
As as a spy, you know the first packet sent to bob, had a value of 589505.
The packet bob sent back to alice, after applying his key, has a value of 326166
The message sent *back* to bob after alice removed *her* key, had a value of:
What are the values of keyA, keyB, and what is the value of the msg?4

Because Yes we can!
Poll, if you had a week of vacation, which of the following would you play, if any?
Is there any exact way to get the product of all primes under n multiplied together, without explicitly knowing what those primes are?
Lets call this number V.
Because hypothethetically, if we calculate from the *base* of V, then we can derive easy divisibility rules for V-1 and V+1, as laid out
And then, unless I've misunderstood something, the problem of factorization has been changed from division into an addition and subtraction problem.12
In reference to Berkmann18's complaints about his flat.
1. found a business that does apartment listings in the style of social media.
2. focus on helping people find less-shit room mates. Like yelp, but for assholes.
3. make your money on helping millennials and gen-z manage and automate rental payments, because both those generations HATE having to look people in the eyes, having to ask for money, or anything involving negotiation. Automate the pain, monetize their avoidance habits.
4. Dashboard for splitting bills, handling rental and sub-let agreements, and divying up rental payments.
5. Get paid by geolocated advertisers for small business services, e.x. roof repair, plumbing, lawn mowing, pool cleaning, etc.
6. That positions you to do strategic partnerships with companies that provide platforms for small business providers, like angieslist.
Had this idea a while back but pursuing something else and just wanted to put it out there for people more capable than me. Lot of great developers out there that beat around for good ideas, and then there are a lot of people with good ideas who don't have the skills to implement.
Call it flattmates, or snagahome, or something like that.
On the offchance anyone decides to go for it, and you get funded, hire me to do grunt work, thats all the thanks I want.
Also I accept payment in blowjobs and beer.3
I'd like to thank a certain person, who will remain unnamed, for some amazing advice and feedback. There are some truly great people out there, and you wont know until you go and look for them.
She showed me I'm not Brain (knew that one), but I'm probably not Pinky either.
Though I still desire to build giant robots and topple cities like Godzilla playing jenga.
Dont let your memes be dreams.5
I'm not real big on asking for help but I'm kinda nervous about applying for my first real programming gig. And I was hoping someone here would be willing to conduct a mock interview with me because I think it would help to get over my jitters and iron out where I might need to practice.
I'm applying for junior python and SQL based positions and I'd really appreciate if anyone would help me practice for an interview.
I'm available most hours Friday, Saturday, and Sunday and if you're willing you can contact me here or at email to setup a phone, screen share, or web interview.
My email is email@example.com
When you're told something, how many times do you have to be told before you are personally convinced?11
Just curious, who here plays escapist and wishes it were multiplayer? Or dont starve (well that's multiplayer).2
Reading over at zerohedge.
And I just wanted to comment on what this one guy posted:
"People that show up on time, dressed to work, not stoned. People that don't stop in the middle of the day to take care of personal matters. People that deliver to the right location. People that don't steal or damage product.
We pay well over the national average for final mile truck drivers. 80% of the ones you get are worthless. The ones that do a good job we reward handsomely to keep them. We have had open reqs for two years now that we can't fill at just about any wage. "
If all the people you hire leave, or no one wants to work for you for any wage, the problem isnt the pool of new hires. The problem is you.
Like a certain fast casual chain that claim they train their employees, and then just toss line cooks on the line and scream at everyone on the line.
Saw it while I was at an interview. Seen it in other
Train your fucking people.
"Good" is now a synonym for "people I dont want the expense of training, and people trained at someone elses expense."
Train your fucking people or gtfo of busines because you have no business being in business otherwise.2
How do you deal with coworkers trying to take over areas of your work?
Especially if they are very arrogant or entitled about it?
Cant talk to the boss, boss doesnt care about the issue. Has repeatedly lead to drama in the past with this guy. He likes to point at his chest while legit screaming "I'm the expert! This job belongs to me. Its mine because I was here first."
Even though the job was given to me.
And worse when I push against this nonsense my boss tells me to stop creating drama.
Like wtf. You gave me a job to do, and this asshole is horning in on my work and taking credit.
I got put on backend office work (because I cant afford to take even a day) while I recover and dont know how to deal with this dickhead.2
I struggled with weather to post this but I feel like I have to. I didnt want to feed into the fear or give 'them' any more reason to argue against common sense but I guess it cant be helped.
The reason I was gone for a while was because I went and got my vaccination.
In less than half hour after getting the vaccine, I was in the ICU. The staff told me I had a stroke possibly from clotting and inflamation. I couldnt feel my arm or anything below my shoulders. Yes really.
Apparently I "died" for a little while and when they brought me back I was in a coma for almost a week.
I'm back home now and I still dont fully understand what happened. Still have numbness, and horrible headaches, and can barely think straight sometimes, but the doctors told me that I didnt suffer any permanent brain damage according to my scans.
Also they told me I had old damage to my left and right temporal lobe, which makes sense because I have always suffered problems with short term memory and other issues.
And I'm just at a loss how this could happen. I have no serious injuries. We were told this is safe.
And this is the exact reason I didnt want to post it, because now tards will come in and be "lololol serves you right vaxxer!"
If I knew the side effects were this bad maybe I would have changed my mind but no one told me! I mean I think I still would have got it because we have to protect vulnerable people, but still.
The hospital assured me it wasnt the vaccine and must have been an underlaying condition, but I'm not so sure. I just happen to have a pre-existing problem that I dont know about that causes a stroke and paralysis only half an hour after the shot?
And now I dont know if I'll ever be ok. And doctors warned me I may suffer more strokes and to avoid physically demanding tasks for a while. My primary job is construction (not by chooce). Now I face the prospect of not even being able to work my existing job or do the things I love, like hiking, anymore. So much of the world doesnt make any sense right now and I just dont know what to believe anymore.
Tards will probably be in shortly to suggest I check for microchips or test fucking magnets on myself.
No, just stop.9
Hey I'm back!
Wasnt able to use my phone, was in the hospital for my penis size reduction operation.15
I've been wondering about SQLite, how it decides to execute your SQL and then generates byte code to do it.
Hypothetically if you were sufficiently familiar with the quarks of SQLite at a low enough level, one could craft web requests on sites running it, such that the results of each subsequent request, leave the SQLite engine in a particular state, no?
Suppose previous states, when interleaved with subsequent carefully crafted states, lead to execution and injection vulnerabilities.
Arent ideas like this what lead to the randomization of jump addresses in modern architectures?8
Let some number P be the product of two factors, A and B
Let the iterations of A*1..2..3..N up to B+1 be a directed graph.
Would this graph be eularian?
If so then it should be possible to use the BEST algorithm to count the number of eularian circuits, yielding B, no?
Edit: this is supported by the following text:
An arborescence can equivalently be defined as a rooted digraph in which the path from the root to any other vertex is unique.
* * *
Where the product of any two primes is unique, the path to it across our graph here, is also unique.
Whats it called when you subtract 1 or more from a number and get its decimal component back as result?
For example, lets say
((x+y)/y) - 1 == x/y
((x+y)/y) == d('1.000041160213365071474861471983496528380123531238424473420976789')
and the right hand side is
(x/y) == d('0.000041160213365071474861471983496528380123531238424473420976789')
Is this trivial or something interesting or a concept that others are familiar with and I just haven't learned?7
Trees -> declarative programming
Loops -> functional programming
Sequences -> imperative programming
Graphs -> dynamic programming
Good mapping, yeah or no?15
"In Python 3, exec is a function; its use has no effect on the compiled bytecode of the function where it is used."
Found in a stackoverflow post.
So wait, you mean to say, you could hide code in a pyc file or am I mistaken?
How is this not a security concern?12
To anyone who ever got annoyed at all the "thanos was right" people who repeated it to the annoyance of everyone, for months on end: the studio did it so the Hollywood misanthropes could sell their doomporn malthusian claptrap to the subset wanna-sound-smart crowd of farthuffering intellectuals in the public.
Now you can't walk six feet without every other dude and their f*cking dog spouting off at the mouth about "thanos was right!"
Like no shit? You DONT SAY! None of us could have possibly had this brilliant and never-before-experienced flash of revelation opinion of thanos. As insightful and innovated as the man who once realized cat rhymes hat. Truly a legend worthy of admiration and accolade.
Hes a mass murderer. An absolute monster based purely on the scale of his actions. The scale of his murder elides over any moral considerations of intent or pretensions of intent, and sincerity no more absolves him than sincerity absolves a terrorist.
What this movie should have done for all the thanos dickriders or would-be dickriders, is taught a valuable eye opening lesson: how easy it is make people in general agree with anything--anything at all, no matter how appalling, how monstrous, so long as the instigator is framed sympathetically on the golden screen. It should have opened your eyes about just how powerful and susceptible you and anyone else are to propaganda.
Dont believe me? Take your most hated politician, left or right. Now imagine they did exactly what thanos did.
Would you still be ok with it? Of course not. Because the fallacy here is to impute moral or logical worthiness onto a cause simply because the agent of it is sincere or can be empathized with.
More generally, Thanos actions presuppose that population control is not a social and technological issue, which it is, and like everything else will come under the pressure of technology. On a long enough timeline then it's a self limiting problem (by definition).
Which is what makes this example of propaganda so vicious: precisely because this subset of the public is so vacuous and infantilized as to actually believe movie logic malthusianism is the same as reality.
The reality is the material conditions of life, even in places like*india* have so markedly improved because of technology *exclusively* iterated on *solely* because of population pressure, that many of the most impoverished people live in such wealth compared to their ancestors just five thousand years ago, that they are kings by comparison.10
Minimum wage employers and restaurants asking "and why should we hire you?".
You have 40 vacancies in your area for just your company alone.
You're paying $13.25 an hour when only a year ago you were paying $9.75.
Why should we hire you?
F*ck you, pay me, that's why.
You're not f*cking NASA
You're a God damn chain restaurant with a 40% turnover rate, who's employees probably shoot up in the bathroom on the rare occasion they even get a break.
I looked at the guy with all the annoyance I could muster, stared him down for a good five seconds and said. "You pay a few dollars over minimum. You're job is not important enough to even ask that question. Have a nice day." And got up and left.
Dude followed me and stuttered " hold up. I was just..."
But I was already out the door.
You were just what mark? Asking a dumbfuck question as if you had any leverage at all?
Your competitor *across the street* is offering 50 cents *more* per hour, and has guaranteed breaks.
What, did you forget 2008 and how you treated millions of people as disposable? The little part where you and most american industries demanded passion, without pay raises? Promotions without benefits? The jobs that if you worked hard, rather than a promotion or a pay raise, your reward was more work and less hours to finish?
You assholes thought we forgot about that? How you shipped millions of jobs overseas, blamed it on "automation" (chinese and indian slave labor), and then pointed the finger at millions of impoverished people as "lazy" in places like Detroit and Pittsburgh and told them "you just got to work harder and smarter!" Or "just get a small loan and create the next google!" from the comfort of your yachts? I'm looking at you bane corp.
No, now the shoes on the other foot motherf*ckers. Hows it feel needing all *us* commoners? "Why should we hire you?"
No, why should *I* WORK FOR YOU?
Cuz I saw THREE dirty tables coming in. A line of people that could be being served. A line that could have been optimized with the proper table count and some simple changes. A menu that doesnt even incentivize your biggest sellers and a dozen other things your store is doing wrong.
Think mark, think!
This is one of those braindead questions employers paying sub $18 an hour ask, because they suffered so much brain drain from years of payola profits from too-big-to-fail wallstreet bailouts, that they forgot they are not king midas, unless they are the king midas of shit, because increasingly everything corporate America touches turns into shit.
And while were on the subject, stopping bringing in outside management to stores. It destroys team cohesion, staff morale, pisses off people *on site* who *actually know* the team, the stores daily activities and processes, and who are better fit for that role. You bring in disinterested outside management, and it's one of the biggest red flags I've ever seen: these smarmy selfcongratulating f*cks who know nothing about the particular store, have no connection to the staff, go on firing sprees or alienation-sprees to hire in friends, fuck up the schedules because again they know nothing about the employees, and then move on after a few years to greener pastures, leaving a barren radioactive wasteland of chain smokers and burnt out staff in their wake.
Dear corporate America, your free ride on the public's good will is over. It's over.
Now you're in the bitch seat. Come sit at my desk and explain to me, EXPLAIN TO ME, why I should sweat and labor to save your shitty company hemorrhaging money like a bleeding crack-addicted hobo dying with a sucking chest wound from a chicago skidrow friday-night drive-by?
You dont deserve it. Your management and company culture is worse than incompetent. It's full of smiley guys expounding about their passion for customer service while giving each other sloppy BJs in broom closets, a veritable cornucopia of cult-like corporate dick suckers *and* dickheads, proclaiming, no...PROFESSING (hence "professional") their undying allegiance and dedication to their corporate family with the intensity of cujo, foaming at the mouth, or Mitt Romney preparing for a photoshoot, plastic smiles and feigned laughs.
Dont forget to wipe your chin, asshole. It's not Ronald McDonald your blowing, but it's definitely not Gordon f*cking Ramsey either.
Would you like fries with that?92
Hang with me! This is *not* a math shitpost, I repeat, it is NOT a math shitpost, not entirely anyway.
It appears there is for products of two non-trivial factors, a real number n (well a rational number anyway) such that p/n = i (some number in the set of integers), whos factor chain is apparently no greater than floor(log(log(p))**2)-2, and whos largest factor is never greater than p^(1/4).
And that this number is at least derivable, laboriously with the following:
And assuming you have the factors of p/z = jkl..
then instead of doing
p/(jkl..) = z
you can do
p-(jkl) to get the value of [result] whos index is a-1
Getting the actual factor tree of p/z is another matter, but its a start.
Edit: you have to provide your own product.
Preferably import Decimal first.3
Glass door: now almost completely fucking useless.
Glassdoor now requires you to login to even read the site. You log in and then AFTEr logging it, it informs you that you have to contribute an "anonymous review" to read the others.
Completely fucking useless and defeat the one reason it originally existed for: to help people review a company *before* applying.
Good job you morons at glassdoor, you had one job.
Of the following names, at least one of them is likely certifiably retarded (or has options against the company stock):
Christian Sutherland Wong (ceo)
Anthony Moisant (cio, senior vp)
Kate Ahlering (chief sales)
Owen Humphries (senior vp)
Annie Pearl (chief product officer)7
I've started using PyQT5 and I'm surprised at how easy it's been so far.
Anyone familiar with it, and if so, what kind of obstacles I can expect to encounter making custom widgets and styling?6
Can anyone see where this repeats predictably?
Decimal('507.724375') / Decimal('173.2336')
I set the precision to 500+ digits and I'm not seeing any repetitions at a glance.
If there isn't, this is my new favorite irrational number.30
Both these kits (for doing interactive graphs) are pretty cool:
one for chemical structures (RDKit):
Making interactive graphs in python:
I just found something cool on accident.
Assuming you start the fibonacci sequence on 2, you can find any of the fibonacci numbers for a given index with a simple trick:
Let Phi = 1.618
Let your index n = n+1
Floor(phi**(n+1+0.328))+1 = the fibonacci number at index n in the sequence.
This probably breaks down past some point but its nifty.22
Besides all the other problems with js, I have to ask the experts:
How or in what way does this hurt development as opposed to languages that make distinctions between prototypes and objects?8
