1. Do you know why my computer is so slow?
2. What cellphone do you recommend me to buy? (They always end up buying the cheapest)
3. What do you do at work? (Answer: "I create applications". Anything more complex than that is not going to be understood or they will loose interest)
4. Something is wrong with the: [TV, Cellphone, microwave, etc.]. Could you please take a look? (Believe or not, if something works with electricoty, my family thinks I can fix it).
5. Is it true that if I send this WhatsApp message to all my contacts I will have more options?
6. I need to build an application that (pretty much The Matrix), how much time do you need and how much would cost? Don't you dare to give me wrong numbers. (We have to see the future)
7. (Continuing the previous point, a non-technical client) I don't think that would take so much time/money. (Every time)
8. I want to use the latest Front-End frameworks. I want to see all those beautiful animations in my page and that it runs smoothly... I also need that it runs in IE 5.
9. So, you have been working in the back end? If you don't have a screen to show to the client is like you didn't do anything in this sprint.
10. Why haven't you built and million dollar application? Everybody is doing that right now....
Yep, those are only a few downsides of our profession if we count family, friends and even co-workers. But I can't imagine myself doing anything else.6 -
Went to see Jason Bourne last night. No spoilers, but I'm guessing this is how the writers came up with the story:
Writer 1: Let's make it super techie
W2: Yeah, that way it's about current issues, like Internet privacy.
W1: Should we hire a tech consultant so we get things right?
W2: Nah, I saw the Matrix once, I understand computers.
Actual line from film:
"Use SQL to corrupt their database"

What I'm posting here is my 'manifesto'/the things I stand for. You may like it, you may hate it, you may comment but this is what I stand for.
What are the basic principles of life? one of them is sharing, so why stop at software/computers?
I think we should share our software, make it better together and don't put restrictions onto it. Everyone should be able to contribute their part and we should make it better together. Of course, we have to make money but I think that there is a very good way in making money through OSS.
Next to that, since the Snowden releases from 2013, it has come clear that the NSA (and other intelligence agencies) will try everything to get into anyone's messages, devices, systems and so on. That's simply NOT okay.
Our devices should be OUR devices. No agency should be allowed to warrantless bypass our systems/messages security/encryptions for the sake of whatever 'national security' bullshit. Even a former NSA semi-director traveled to the UK to oppose mass surveillance/mass govt. hacking because he, himself, said that it doesn't work.
We should be able to communicate freely without spying. Without the feeling that we are being watched. Too badly, the intelligence agencies of today do not want us to do this and this is why mass surveillance/gag orders (companies having to reveal their users' information without being allowed to alert their users about this) are in place but I think that this is absolutely wrong. When we use end to end encrypted communications, we simply defend ourselves against this non-ethical form of spying.
I'm a heavy Signal (and since a few days also Riot.IM (matrix protocol) (Riot.IM with end to end crypto enabled)), Tutanota (encrypted email) and Linux user because I believe that only those measures (open source, reliable crypto) will protect against all the mass spying we face today.
The applications/services I strongly oppose are stuff like WhatsApp (yes, encryted messages but the metadata is readily available and it's closed source), skype, gmail, outlook and so on and on and on.
I think that we should OWN our OWN data, communications, browsing stuffs, operating systems, softwares and so on.
This was my rant.17 -
Ticket: “feature [x] doesn’t work”
Me: “I’ll need more details: how do I reach feature [x]? In which of the three projects you assigned me is that?”
Manager: “the design is in the ticket”
Me, in my head: “can you effin listen to what I told you before giving air to your mouth?”
Me, in person: “yeah I just need to know which project this refers to and how to reach it”
Manager: “but you have to open the ticket as a separate page!”
Me: “sure!” *waits 15 min, opens a ticket for more details, assigns it to manager, flags as blocking, flags the other one as blocked*
5 mins later: details are given and I can proudly fox it by remembering the manager they have to login in order to see feature [x]
Later in the workweek:
Manager at 8:00 URGENT FEATURE! MUST BE DELIVERED BY EOD
Me, 10:00 “can jump on it, need authorisation for [a procedure]
Me, 11,12,13,15,16,17:30: pings for an answer
Manager, 17:58 “ah sorry didn’t see, we can do it tomorrow”
Is this the matrix? Am I being stopped from developing cause I am randomly accessing matrix’s code without knowing it? Is this the Truman show? And most importantly: can I please take part to a manager hiring session? I am curious to see how tf you hire such peculiar people.10 -
Finally, the jeezless present is done.. fuck this shit, where's my booze and my bed?! 😒
Anyway, it's essentially a power bank with LED's attached to it. The LED matrix is at the back side and looks reasonably decent (but I don't wanna disclose the age it's displaying). It's powered through a 47ohm resistor and is directly attached to the 5V lines. Yellow LED's with 2V voltage drop that have each number completely parallelized, and then those numbers are put in series to increase the combined forward voltage of the LED's to 4V. That way the circuit is around 80% efficient (resistor drops 1V, LED's drop the remaining 4V). Other than that, nothing too special. It did take 2 nights to build though.. way too much for a mere formality 😑

PHP arrays.
The built-in array is also an hashmap. Actually, it's always a hashmap, but you can append to it without specifying indexes and PHP will use consecutive integers. Its performance characteristics? Who knows. Oh, and only strings, ints and null are valid keys.
What's the iteration order for arrays if you use them as hashmaps (string keys)? Well, they have their internal order. So it's actually an ordered hashmap that's being called an array. And you can produce an array which has only integer keys starting with 0, but with non-sequential internal (iteration) order.
This array weirdness has some non-trivial implications. `json_encode` (serializes argument to JSON) assumes an array corresponds to a JSON array if its keys are consecutive integers in increasing order starting with 0, otherwise the array becomes a JSON object. `array_filter` (filters arrays/hashmaps using callback predicate) preserves keys, so it will punch holes in the int key sequence if non-last items are removed, thus turning arrays into hashmaps and changing your JSON structure if you forget to discard keys before serialization.
You may wonder how JSON deserialization works, then? There's a special class for deserialized JSON objects, `stdClass`. It's basically a hashmap too, but it's an object, not an array, and all functions that would normally accept arrays won't work with it. So basically its only use is JSON (de)serialization. You can even cast arrays to objects, producing `stdClass`.
Bonus PHP trivia:
Many functions return nonsensical values. `preg_match`, the regex matching function, returns 1 for success, 0 for no matches and false for malformed regular expression. PHP supports exceptions, so it could just throw one on errors. It would even make more sense to return true, false and null for these three cases. But no, 1, 0 and false. And actual matches are returned by output arg.
`array_walk_recursive`, a function supposed to recursively apply callback to each element of an array. That's what docs say. It actually applies it to leafs only. It will also silently accept object instead of array and "walk" it, but without recursing into deeper objects.
Runtime type enforcing is supported for function arguments and returned values. You can use scalar types, classes, array, null and a few special keywords. There's also a `mixed` keyword, which is used in docs and means "anything". It's syntactically valid, the parser will accept it, but it matches no values in runtime. Calling such function will always cause a runtime error.
Strings can be indexed with negative integers. Arrays can't.
ReflectionClass::newInstanceWithoutConstructor: "Creates a new class instance without invoking the constructor". This one needs no commentary.
`array_map` is pretty self-explanatory if you call it with a callback and an array. Or if you provide more arrays of equal length via varargs, callback will be called with more arguments, one from each array. Makes sense so far. Now, you can also call `array_map` with null instead of callback. In that case it treats provided arrays as rows of a matrix and returns that matrix, transposed.5 -
I will never stop being impressed by how detailed this scene in The Matrix Reloaded was.
Trinity is trying to hack into the terminal and shut down the power grid.
nmap (network map) is a linux tool for network discovery.
It is absolutely believable that in a post apocalyptic future where computers rule the earth, the entire power grid would be on a network that you can scan for like this and shut down.
Its a such a minor detail, but I'm really happy that the writers consulted with actual programmers.

Buckle up, it's a long one.
Let me tell you why "Tree Shaking" is stupidity incarnate and why Rich Harris needs to stop talking about things he doesn't understand.
For reference, this is a direct response to the 2015 article here: https://medium.com/@Rich_Harris/...
"Tree shaking", as Rich puts it, is NOT dead code removal apparently, but instead only picking the parts that are actually used.
However, Rich has never heard of a C compiler, apparently. In C (or any systems language with basic optimizations), public (visible) members exposed to library consumers must have that code available to them, obviously. However, all of the other cruft that you don't actually use is removed - hence, dead code removal.
How does the compiler do that? Well, it does what Rich calls "tree shaking" by evaluating all of the pieces of code that are used by any codepaths used by any of the exported symbols, not just the "main module" (which doesn't exist in systems libraries).
It's the SAME FUCKING THING, he's just not researched enough to fully fucking understand that. But sure, tell me how the javascript community apparently invented something ELSE that you REALLY just repackaged and made more bloated/downright wrong (React Hooks, webpack, WebAssembly, etc.)
Speaking of Javascript, "tree shaking" is impossible to do with any degree of confidence, unlike statically typed/well defined languages. This is because you can create artificial references to values at runtime using string functions - which means, with the right input, almost anything can be run depending on the input.
How do you figure out what can and can't be? You can't! Since there is a runtime-based codepath and decision tree, you run into properties of Turing's halting problem, which cannot be solved completely.
With stricter languages such as C (which is where "dead code removal" is used quite aggressively), you can make very strong assertions at compile time about the usage of code. This is simply how C is still thousands of times faster than Javascript.
So no, Rich Harris, dead code removal is not "silly". Your entire premise about "live code inclusion" is technical jargon and buzzwordy drivel. Empty words at best.
This sort of shit is annoying and only feeds into this cycle of the web community not being Special enough and having to reinvent every single fucking facet of operating systems in your shitty bloated spyware-like browser and brand it with flashy Matrix-esque imagery and prose.
Fuck all of it.20 -
Gender Bending For Fun and Profit.
I love how in the 'make your avatar' area, if you select female, and then click facial hair, theres nothing to select from.
Like a massive fuck you to every gender bending "down with meritocracy" purple haired dicksniffer in sanfran.
Also I'm sorely disappoint for desk items, theres no
1. giant dildos
2. anime figures/weeb shit
3. mini monoliths (I asked the site devs about this, they replied "we can't do that dave.")
4. a shirtless option for my female avatar
5. edgy scrolling numbers and code, like in the matrix
6. hoodies. They're the modern leather jacket.
7. Big nasty gnarly biker beard which I'm currently in the process of growing. How am I supposed to intimidate other anonymous cowards and mock them over the size of their beard compared to my own avatar's e-beard size? It's quiet girthy and lengthy, I assure you!
This is completely unrelated, but I thought devducks were like quick one-off debug sessions that could be bought from other devrant users.
I was disappointed when I discovered it was just merch.
On the otherhand I'm glad as fuck it's not. Site would be flooded by broken-english speaking goat humping dickheads.
How am I supposed to show off my ability to code with completely unrelated avatar change ups when no one will allow me to emasculate my avatar?16 -
Look, I get that it's really tricky to assess whether someone is or isn't skilled going solely by their profile.
That's alright.
What isn't center of the cosmic rectum alright with the fucking buttsauce infested state of interviews is that you give me the most far fetched and convoluted nonsense to solve and then put me on a fucking timer.
And since there isn't a human being on the other side, I can't even ask for clarification nor walk them through my reasoning. No, eat shit you cunt juice swallowing mother fucker, anal annhilation on your whole family with a black cock stretching from Zimbabwe to Singapore, we don't care about this "reasoning" you speak of. Fuck that shit! We just hang out here, handing out tricks in the back alley and smoking opium with vietnamese prostitutes, up your fucking ass with reason.
Let me tell you something mister, I'm gonna shove a LITERAL TON of putrid gorilla SHIT down your whore mouth then cum all over your face and tits, let's see how you like THAT.
Cherry on top: by the time I began figuring out where my initial approach was wrong, it was too late. Get that? L'esprit d'escalier, bitch. I began to understand the problem AFTER the timer was up. I could solve it now, except it wouldn't do me any fucking good.
The problem? Locate the topmost 2x2 block inside a matrix whose values fall within a particular range. It's easy! But if you don't explain it properly, I have to sit down re-reading the description and think about what the actual fuck is this cancerous liquid queef that just got forcefully injected into my eyes.
But since I can't spend too much time trying to comperfukenhend this two dollar handjob of a task, which I'd rather swap for teabagging a hairy ass herpes testicle sack, there's rushing in to try and make sense of this shit as I type.
So I'm about 10 minutes down or so already, 35 to go. I finally decipher that I should get the XY coords of each element within the specified range, then we'll walk an array of those coordinates and check for adjacency. Easy! Done, and done.
Another 10 minutes down, all checks in place. TEST. Wait, wat? Where's the output? WHERE. THE FUCK. IS. THE OUTPUT?! BITCH GIMME AN ANSWER. I COUT'D THE RETURN AND CAN SEE THE TERMINAL BUT ITS NOT SHOWING ME ANYTHINGGG?! UUUGHHH FUCKKFKFKFKFKFKFKFUFUFUFFKFK (...)
Alright, we have about 20 minutes left to finish this motorsaw colonoscopy, and I can't see what my code is outputting so I'm walking through the code myself trying to figure out if this will work. Oh, look at that I have to MANUALLY click this fucking misaligned text that says "clear" in order for any new output to register. Lovely, 10/10 web design, I will violate your armpits with an octopus soaked in rabid bear piss.
Mmmh, looks like I got this wrong. Figures. I'm building the array of coordinates sequentially, as a one dimentional list, which is very inconvenient for finding adjacent elements. No problem, let's try and fix that aaaaaand... SHIT IM ALMOST OUT OF TIME.
QUICK LYEB, QUICK!! REMEMBER WHAT FISCELLA TAUGHT YOU, IN BETWEEN MOLESTING YOUR SOUL WITH 16-BIT I/O CONSOLE PROBLEMS, LIKE THAT BITCH SNOWFALL THING YOU HAD TO SOLVE FOR A FRIEND USING TURBO C ON A FUCKING TOASTER IN COMPUTER LAB! RUN MOTHERFUCKER RUN!!!
I'm SWEATING. HEAVILY. I'm STEAMING, NON-EROTICALLY. Less than 10 minutes left. I'm trying to correct the code I have, but I start making MORE dumbfuck mistakes because I'm in a hurry!
5 minutes left. As I hit this point of no return, I realize exactly where my initial reasoning went wrong, and how I could fix it, but I can't because I don't have enough time. Sadface.
So I hastily put together skeleton of the correct implementation, and as the clock is nearly up, I write a comment explaining the bits I can't get to write. Page up, top of file, type "the editor was shit LMAO" and comment it out. SUBMIT.

I didn't leave, I just got busy working 60 hour weeks in between studying.
I found a new method called matrix decomposition (not the known method of the same name).
Premise is that you break a semiprime down into its component numbers and magnitudes, lets say 697 for example. It becomes 600, 90, and 7.
Then you break each of those down into their prime factorizations (with exponents).
So you get something like
>>> decon(697)
offset: 3, exp: [[Decimal('2'), Decimal('3')], [Decimal('3'), Decimal('1')], [Decimal('5'), Decimal('2')]]
offset: 2, exp: [[Decimal('2'), Decimal('1')], [Decimal('3'), Decimal('2')], [Decimal('5'), Decimal('1')]]
offset: 1, exp: [[Decimal('7'), Decimal('1')]]
And it turns out that in larger numbers there are distinct patterns that act as maps at each offset (or magnitude) of the product, mapping to the respective magnitudes and digits of the factors.
For example I can pretty reliably predict from a product, where the '8's are in its factors.
Apparently theres a whole host of rules like this.
So what I've done is gone an started writing an interpreter with some pseudo-assembly I defined. This has been ongoing for maybe a month, and I've had very little time to work on it in between at my job (which I'm about to be late for here if I don't start getting ready, lol).
Anyway, long and the short of it, the plan is to generate a large data set of primes and their products, and then write a rules engine to generate sets of my custom assembly language, and then fitness test and validate them, winnowing what doesn't work.
The end product should be a function that lets me map from the digits of a product to all the digits of its factors.
It technically already works, like I've printed out a ton of products and eyeballed patterns to derive custom rules, its just not the complete set yet. And instead of spending months or years doing that I'm just gonna finish the system to automatically derive them for me. The rules I found so far have tested out successfully every time, and whether or not the engine finds those will be the test case for if the broader system is viable, but everything looks legit.
I wouldn't have persued this except when I realized the production of semiprimes *must* be non-eularian (long story), it occured to me that there must be rich internal representations mapping products to factors, that we were simply missing.
I'll go into more details in a later post, maybe not today, because I'm working till close tonight (won't be back till 3 am), but after 4 1/2 years the work is bearing fruit.
Also, its good to see you all again. I fucking missed you guys.9 -
Got a mathematics library I develop and maintain. Someone filed a feature request ticket for matrices of matrices. As in, each value of the primary matrix is another matrix. Not understanding why anyone would need such a convoluted concept, I asked for clarification.
Response: "This piece of shit library isn't feature complete without it, now stop being a lazy fag in your mother's basement and actually do something"
Lololololol. Sure thing. Let me go waste two or more weeks of my life developing something i've never seen used in math, without any justification beyond "feature".4 -
Recently I flashed Android 9 (Pie) on my Nexus, but to this day I still haven't logged into Google from it. One reason is because I don't know my password and I didn't git clone my password store yet (where it's contained). Another reason is because I want to reclaim my privacy and not be a data battery for a Matrix of convenience that feeds itself with my personal information. Eh, it sorta works out I guess. Yalp is an amazing alternative to the Play Store, and even offers its own shadow accounts to use along with Google Play.
One problem though, while I've noticed that I could log in with my own account to get all my premium apps (couple hundred euros worth, so not easy to just discard) it apparently violates Google Play's ToS to do so from a third-party app. So I'm a bit hesitant to do that. Do you know of any viable alternative way to preserve my privacy yet install, keep and have validated those premium apps? I could download them from e.g. BlueStacks and export the apk's, but that'd be tedious and wouldn't be able to get those apps validated on my phone unless I log into Google there as well (which kinda defeats the purpose). Any suggestions?23 -
Hey there 👋
I am more or less throwing any burden (WhatsApp, Facebook, Google etc.) out of my life. Of course I will continue using the Google account for YouTube and some games that need it.
That's what it looks like right now:
Raspberry Pi 3B+
✅ webserver
- forum - complete (atm just for me)
- blog - no ideas and just installed october cms and nothing done yet
- nextcloud - complete and filled with my porn... eeh... data
✅ mailserver
(missing spamassassin, clam or sth. like this but it's working 😂)
✅ matrix-synapse
(as an additional alternative to messengers)
______________
Raspberry Pi 2
✅ catches dust
(any ideas?)
Of course, many more configurations and the like are necessary before everything is ready... but what then or what else is there?
At the moment I still use WhatsApp. Just wanna take time before sending everyone a message about changing the messenger and that it should be important for thinking about the own privacy, which alternatives there are bla...
Edit: For passwords I'm using Myki - didn't hear anything bad about it yet and it's very easy to use (Firefox add-on, Android app).
I love my passwords with 200 characters 😂
Maybe someone's knowing more about them?
Hope I didn't forget a thing... thanks in advance aaaaaaand... I'm gone. ☺23 -
I don't know if this is a problem only in Belgium or also in other countries but while I love Bluetooth for audio playback (headsets, speakers and everything) despite being extremely convoluted as a protocol.. FUCK Bluetooth keyboards.
Several of them I've tried. Several of them, from various brands. Pairing, setting the Belgian keyboard layout (which on that shitty Android 7.0 tablet that I want to use the fucking things with apparently has to be done *every fucking time you connect*, because reasons) all well. Except half the keys don't fucking map properly. A keymap, it doesn't get easier than that! How hard is it to make buttons map to the right keys!? They're literally fucking push buttons on a matrix! Seeing which points in the circuit make contact and sending that off to wherever it needs to go!
And to put the icing on the cake? USB keyboards with the same fucking layout settings work without any problems. So it's extremely likely that it's something in those shitty keyboards' controllers or Bluetooth going full rart on all of them.
Of course, Bluetooth being as convoluted as it is, manufacturers just copy each others' implementations of it if they can.. so there's that.
Can really nobody make a product halfway decent anymore before putting it on the market!?
Another one bites the dust.. JUNK!!! Every single goddamn one of them!1 -
So technical interview today but woke up (6am) and started thinking about it and it led to this rant about algorithms. This is probably going into a Medium post if I ever get around to finishing it but sort of just wanted to share the rant that literally just went off in my mind.
*The problem with Algorithms Technical Interviews Is They don't test Real skills*
Real world problems are complex and often cross domain combining experience in multiple areas. Often the best way is not obvious unless you're a polymath and familiar with different areas, paradigms, designs. And intuitively can understand, reason, and combine them.
I don't think this is something a specific algorithm problem is designed to show. And the problem is the optimal solution to some of these and to algorithm design itself is that unless you train for it or are an algorithm designer (practice and experience), you can only brute force it in the amount of time given.
And quite frankly the algorithms I think we rely on daily weren't thought of in 30 minutes. The designers did this stuff for a living, thought about these problems for days and several iterations… at least. A lot were mathematicians. The matrix algorithm that had a Big O of 7N required a flash of insight that only someone constantly looking and thinking about the equations could see.
TBA
-system design
-clean readable coding practices
...
TLDR: I could probably go on and on about this stuff for hours jumping from item/example/area to the next and back again... But I don't think you can test these (~20) years of experience in a 1 hr technical interview focused on algorithms...8 -
I. HATE. DELL. WITH. MY. GUTS.
Their low tiers products are full black plastic overpriced fuckshit, if you press too much the cover you can actually destroy your display. Fuck shitty laptops and fuck this shitty laptop in particular. It's slow. It's so slooooooow. It's everflying fucking slow motion, being on the web is like being in the matrix while dodging bullets made of wordpress plugins. The only good thing I can say is that is living right now, it has been... Three years? I only picked it because of high discount and ubuntu preinstalled (that made me think: oh, maybe they have components that are linux compatible regardless of distros. It was not). I'm enjoying Manjaro, when I'll have the skillz i'm going full Arch.
I will start university this fall. It's going to be a math major. I absolutely need something better than this anyway. I am also freaking out because I don't know which genre of software they could want to make me install and if they're windows/mac only. In the meanwhile I do photography, video, design and as you may suppose Adobe is often my go-to; I also have to build a workstation at home. I am freaking out because WELL FUCK WINDOWS 10 AND ITS PRIVACY NIGHTMARE PERIOD.
Which laptop I buy?
How well does heavy software run in a Windows virtual machine (on the desktop, not the laptop)?10 -
This moment when you help your friend with data conversion code 😀.
By converting "super" mathlab script into real C# application so you don,t need to read the whole freking 1GB file into RAM and writing it into another 1GB matrix in order do save the result because mathlab is crap 😤.
Then that feeling when you want to create better mathlab from scrach in C# and you are actualy succeding 🤔.
Did i mention about grafical blocks for interface like in lego NXT2.0 😏
Is mathlab that crap or is programming that easy?14 -
Taking a 4 month Software Engineering course in University. Spent the last 2 months making Traceability Matrix, Component Diagrams, Deployment Diagrams, Sequence Diagram and not a single line of code was written.
Is this how it works in Industry as well? Lol.12 -
#arduino #led matrix
Hey guys.
So, this is my first led matrix using a 74hc595n, I did all the connections right, isolated the cathodes (-), and when I tested, I only connected one cathode (to test one row, when almost all the lights turned on, in all rows doing a chacing... So I disconnected the negative wire and it still works.
One led in the arduino blinks (L).
GND is only connected to the shift register
All the rows light up doing a colum chase when there is no negative.
I'm astowned.....

Everytime you use OpenGL in a brand new project you have to go through the ceremonial blindfolded obstacle course that is getting the first damn triangle to show up. Is the shader code right? Did I forget to check an error on this buffer upload? Is my texture incomplete? Am I bad at matrix math? (Spoiler alert: usually yes) Did I not GL enable something? Is my context setup wrong? Did Nvidia release drivers that grep for my window title and refuse to display any geometry in it?
Oh. Needed to glViewport. OK.4 -
So I just found out that multi-line editing can copy a matrix of letters and paste it on other lines. This is amazing. Imagine being the person who thought of this feature.1

I turned down another women who was absolutely, 100% flirting with me, because, from what I can gather, she was trying to get out of a relationship with her current boyfriend, a military veteran.
I outright ignored her and then when that failed, I made our work relationship 100% about that, work.
Even though I'm friendly with everyone else.
I'm an absolute shit, aren't I? I feel genuinely bad.
I'm not sure if I did it out of a misplaced sense of honor for a dude who obviously has some ptsd, or because I don't feel like I'm able to connect with anyone anymore.
I feel like I'm alone in this world. Not, like, sexually or anything, but more like I don't want to burden anyone with the shit I'm going through. Like a man on a mission on a sinking ship, and it would be wrong to let anyone else on board.
Like a one-man shit-show, all singing, all dancing, driven to one end, with one purpose. And it'd be wrong to let anyone get attached, or invite anyone else in.
Fuck I got so many irons in the fire. I have an ARG in the works, a full game, a social platform that the code and marketing plan is laid out and I'm saving money for, two more games already planned, plus spending an in-ordinate amount of time with my father and sister and mother as they deal with the loss of my sister, plus volunteering to help the homeless, plus working, plus studying.
I barely sleep.
It's just me. I'm like a cruise missile heading to one destination, to some final destination, I just don't know what. And I don't let anyone in, because then they might see how fucking crazy I am, and how crazy my life is, and how crazy my goals are. Thats not a humblebrag. Thats more of a "wholly shit, I'm so in over my head, I'm fucking drowning" type thing. But I'm not giving up, I'm just going deeper.
And it feels like drowning but somehow I'm okay with it. Like I've passed the crux of loneliness, and settled for going for it all, alone, shooting out of orbit, and saying "fuck it all' to everything and everyone. They say "if you got everything you wanted, everything you wished for, you'd wish you hadn't, which is why god isn't a genie". And lately I've been thinking god doesn't exist, or doesn't care, because he's left it all up to me, and I've fucked it up good and proper, and am on my way to either nothing, or everything I've ever wanted.
Is this what happiness feels like? Or suicide?
I don't know. I mean I really don't. I don't want to die. I think I could stop existing and be okay with it. Having achieved at least a modicum of understanding the universe, at least accomplished something small but meaningful.
Or maybe I'm delusional, driven mad with the full comprehension of human floundering against a meandering existence.
I don't fucking know.
I feel like I'm spinning my wheels, so much, that even two weeks feels like a fucking eternity. I don't sleep anymore. When I do, I escape into my dreams, where I can fly, or float, and the people in my dreams tell me I'm living in the matrix and I believe them..in my dreams. Feel it even.
And when I wake up, the feeling persists. Leaves me in wonderland, for hours after waking.
And I have visions, of going homeless, like some buddha, all the time, and then I say "wake up J, you're fucking crazy! You want to go be some couch surfing homeless bum living off other's good graces? get the fuck outa here! While others suffer, schlep it at whatever job they work, day in day out, toil. In this economy? In this inflation? What a dishonest way of thinking. What a dishonest way of dreaming."
And yet I daydream. Because its the only escape there is from all the world has become.
And I bring joy to others, earnestly, vicariously, because its the closest joy I can feel, when I've become numb.
It is this quasi-permanent sense of alienation that permeates my whole world, a sort of invisible force field that separates me from others, even as I reach out to understand them, to comfort them, to smooth the corners off their world, so that they don't become like I have, something not entirely human, but...other.
Often when we meditate, long and hard enough,
at the center that emerges, at the center of ourselves, we find an abyss, a whole universe, devoid of anything, a perfect silence, mirroring back the cosmos, and other people. Observing, silent, irreducible, implacable.
Sometimes I feel like I don't exist. Sometimes I think others don't exist.
Very often I feel like nothing is real. And that I am playing some sort of game. Not like a video game per se, but that there is a bigger pattern, a hidden pattern to it all, just out of reach, and I'm reaching for it but understanding eludes me.
Not that the universe has made me for some special purpose, but merely that the universe observes me specifically, for no special purpose, other than that it can, whatever trivialities may impede or push forward my life.
As if the universe were bored.24 -

Hello, everyone! Wild Matrix room just appeared: https://matrix.to//...
Hopefully, this one will be of more service to the people of devRant wanting to chat. It is bridged with dRCS, our Discord server, to make a faithful transition of subcommunities. Read the room's description for more detail. 🔗
Just at the start of it all, there is one more event you might like: a canvas like "r/place", but where you join via Lemmy. 🐭 I know, I know, Lemmy is only getting traction - but the community is thriving and making their own cool events already!
This one is called "Canvas": it's a fork of Pxls and a place where you can draw pixel art for all to see. The number of pixels replenishing on each person is limited and it takes time, so we REALLY need to gather together and draw this thing until the event ends!!! What thing? We are going to place a DEVRANT LOGO.
Canvas link and reference will be dropped in the comments below. Let's make devRant proud, for ducks' sake! 🦆🦆🦆🦆🦆🦆🦆🦆🦆🦆🦆🦆🦆🦆🦆🦆🦆🦆
It is recommended to join the channel to coordinate in real time and enjoy a good chat. 😁

Okay then, ex-android user there.
It started with Xperia TX - it was flagship Sony phone back then. It blew my mind when I touched it for the first time. You know, exploring android for the first time in my life was amazing.
It ran just well for about a year. Then it started to fall apart. I need to clarify that I kept it non-rooted, full stock. I'm not into that customization things.
At first, I noticed significant lags. They were everywhere. The longer I used smartphone, the more lags I encountered. I did factory reset, but lags haven't gone anywhere.
Year 2. Front camera stopped working. Battery became unreliable as fuck, going down to 40% and then instantly to zero. What?
Year 3. Camera broke. It refused to start, just giving me "Camera is not available" error.
I tried factory reset again. It helped at first, but month have passed and all that issues came back. And it also became sluggish as fuck.
Got Meizu m3s year ago. The exact same story. Long story short, in one year I got this:
1. Black spots on every picture I take. Much likely a matrix issue.
2. Camera also became slow as fuck, requiring about 10 seconds to even start.
3. Vertical stripes all along the screen. I never dropped my phone, it just appeared once and became brighter and brighter every day I used the phone.
4. Two huge yellow spots on screen. I think it happened because phone's cpu heat up the screen and it broke.
But the most important thing is that fucking lags chased me in every app, they were everywhere. Fucking tiny-ass lags. And they're not going anywhere, they're become more and more significant with time.
Don't say me about oneplus, samsungs and other top android phones. They are conceptually the same, the only different thing is hardware.
That's why I switched. IPhone has its downsides, but it's silky smooth. And my friend's iPhone 4 (not s) feels just as smooth as my brand new se.
I'm not going to jailbreak it. I don't need customizing the hell out of it.
I just needed quick and reliable phone, and SE seems to be exactly what I wanted.
Peace to android folks tho✌️17 -

Imposter syndrome in my early days put myself into a roller coaster of emotions. I always compared myself to others to the detriment of myself.
Thankfully overcame that working with some great guys.
But yeah, coding has impacted life for the best though. The challenge, creativity and constant learning is beautiful. -
Future01
Click, click, click, click.
Tap, tap, tap, tap.
Swipe, swipe, swipe, swipe,.
Scroll, scroll, scroll, scroll.
I’m tired of living on popularity driven planet among animals, where number of clicks on likes, subscriptions and links are worth more than iq, education and experience.
Let’s face it - AI is showing us traffic driven recommendations that sucks. If you’re hooked up to social network and can’t disconnect from it you’re half way to matrix. You probably also disagree with me cause you’re serotonin junkie. You can’t stop like you can’t stop eating for a day. Bubble have you in your hands and whatever you do you probably won’t wake up. To be honest most of us won’t. It’s already to late.
I’m waiting for meta so they can put you in virtual world where you can have what you want and at the same time own nothing. They will put you in some small empty space and give you something to eat how many times you want so you can feel safe and click, tap, swipe, scroll more so they can own this planet.
You will be living only to deliver corporate metadata and you will be happy, cause they will make you happy with giving you emotions that you want to feel at exact moment.
If you get out, you won’t be able to interact cause you won’t know how to behave, you will become wild animal.
By going out you will break the law, cause outside world will be long gone. To move to bar or visit family you will travel with autonomous vehicle that have screens instead of windows.
Eventually you stop going to bar cause it’s unhealthy, you stop going outside cause there’s deadly virus and you can die.
They will take you last thing later with birth control so you can have baby whenever you want and with who you want as long as both parties agree by signing baby nft contract, you don’t have to take care of your baby and be pregnant cause it will be robotized, you will see your baby in meta. You will think you feel it using robot hands.
You will never meet your baby in person.
That’s how matrix will start. We’re half way.6 -
So I promised a post after work last night, discussing the new factorization technique.
As before, I use a method called decon() that takes any number, like 697 for example, and first breaks it down into the respective digits and magnitudes.
697 becomes -> 600, 90, and 7.
It then factors *those* to give a decomposition matrix that looks something like the following when printed out:
offset: 3, exp: [[Decimal('2'), Decimal('3')], [Decimal('3'), Decimal('1')], [Decimal('5'), Decimal('2')]]
offset: 2, exp: [[Decimal('2'), Decimal('1')], [Decimal('3'), Decimal('2')], [Decimal('5'), Decimal('1')]]
offset: 1, exp: [[Decimal('7'), Decimal('1')]]
Each entry is a pair of numbers representing a prime base and an exponent.
Now the idea was that, in theory, at each magnitude of a product, we could actually search through the *range* of the product of these exponents.
So for offset three (600) here, we're looking at
2^3 * 3 ^ 1 * 5 ^ 2.
But actually we're searching
2^3 * 3 ^ 1 * 5 ^ 2.
2^3 * 3 ^ 1 * 5 ^ 1
2^3 * 3 ^ 1 * 5 ^ 0
2^3 * 3 ^ 0 * 5 ^ 2.
2^3 * 3 ^ 1 * 5 ^ 1
etc..
On the basis that whatever it generates may be the digits of another magnitude in one of our target product's factors.
And the first optimization or filter we can apply is to notice that assuming our factors pq=n,
and where p <= q, it will always be more efficient to search for the digits of p (because its under n^0.5 or the square root), than the larger factor q.
So by implication we can filter out any product of this exponent search that is greater than the square root of n.
Writing this code was a bit of a headache because I had to deal with potentially very large lists of bases and exponents, so I couldn't just use loops within loops.
Instead I resorted to writing a three state state machine that 'counted down' across these exponents, and it just works.
And now, in practice this doesn't immediately give us anything useful. And I had hoped this would at least give us *upperbounds* to start our search from, for any particular digit of a product's factors at a given magnitude. So the 12 digit (or pick a magnitude out of a hat) of an example product might give us an upperbound on the 2's exponent for that same digit in our lowest factor q of n.
It didn't work out that way. Sometimes there would be 'inversions', where the exponent of a factor on a magnitude of n, would be *lower* than the exponent of that factor on the same digit of q.
But when I started tearing into examples and generating test data I started to see certain patterns emerge, and immediately I found a way to not just pin down these inversions, but get *tight* bounds on the 2's exponents in the corresponding digit for our product's factor itself. It was like the complications I initially saw actually became a means to *tighten* the bounds.
For example, for one particular semiprime n=pq, this was some of the data:
n - offset: 6, exp: [[Decimal('2'), Decimal('5')], [Decimal('5'), Decimal('5')]]
q - offset: 6, exp: [[Decimal('2'), Decimal('6')], [Decimal('3'), Decimal('1')], [Decimal('5'), Decimal('5')]]
It's almost like the base 3 exponent in [n:7] gives away the presence of 3^1 in [q:6], even
though theres no subsequent presence of 3^n in [n:6] itself.
And I found this rule held each time I tested it.
Other rules, not so much, and other rules still would fail in the presence of yet other rules, almost like a giant switchboard.
I immediately realized the implications: rules had precedence, acted predictable when in isolated instances, and changed in specific instances in combination with other rules.
This was ripe for a decision tree generated through random search.
Another product n=pq, with mroe data
q(4)
offset: 4, exp: [[Decimal('2'), Decimal('4')], [Decimal('5'), Decimal('3')]]
n(4)
offset: 4, exp: [[Decimal('2'), Decimal('3')], [Decimal('3'), Decimal('2')], [Decimal('5'), Decimal('3')]]
Suggesting that a nontrivial base 3 exponent (**2 rather than **1) suggests the exponent on the 2 in the relevant
digit of [n], is one less than the same base 2 digital exponent at the same digit on [q]
And so it was clear from the get go that this approach held promise.
From there I discovered a bunch more rules and made some observations.
The bulk of the patterns, regardless of how large the product grows, should be present in the smaller bases (some bound of primes, say the first dozen), because the bulk of exponents for the factorization of any magnitude of a number, overwhelming lean heavily in the lower prime bases.
It was if the entire vulnerability was hiding in plain sight for four+ years, and we'd been approaching factorization all wrong from the beginning, by trying to factor a number, and all its digits at all its magnitudes, all at once, when like addition or multiplication, factorization could be done piecemeal if we knew the patterns to look for.7 -
Working in an expanding business is mostly fun, can be kind of challenging (for those who don't like to step in and do what's needed). One thing in particular you need to do a lot - is interviews. Lot's of them.
There are alsways two sides of the coin, for sure. But, just a little tip/hint to everyone looking for a job - please, please, please make sure your CV and letter at least makes sense for the position you're trying to get.
This (screenshot) is just one example of things in a CV which really makes me want to shout and kick people out.
It's part of the front page of a CV, for someone who is looking for a position as front-end developer / UX specialist. This person claims to be very interested in UX, and has done wome work already in this field.
Can ANYONE explain to med WHAT THE F*CK this actually means?
1) How many stars can a row have? 10, 6, 8?
2) What does it mean to have 4 starss in PHP knowledge? What's lacking to get 5?
3) What's the scale based on, at all?
And you want me to hire to to do UX of loyalty communication (e-mail, mobile apps, websites/landing pages) for our customers - who in turn have millions of customers/prospects?!?
ARE YOU F*CKING KIDDING ME?
If you can't even make a visualization of your _own_ knowledge which can be interpreted into some sort of competence matrix, but you just use something you think looks cool... Damn, you could at least have tried.

For future generations :
Bring back cocaine to coca cola.
Since 1904 Coca Cola no longer contains extract from cocaine leaves.
Drugs who made us.
If we live in matrix and we are simulated the general rule would be wipe bugs from the system so ex. if all of people were using cocaine cause they drink coca cola the wipe would be remove cocaine from the coca cola. That would fix the cocaine bug. Cause people in 1904 had almost no knowledge about how world looks like, they were using pigeons to deliver messages. If we bring back cocaine maybe we would also bring back those times, when everyone dropped cocaine in 1939 - 35 years old ourselves were fighting to death between each other cause of rehab.
I wonder how many of those non visual but only statistical bugs we have on this planet. Machine learning is just one of the tools we use to learn about them.1 -
Guess it's a sign you haven't had enough sleep when you're creating a slanted div and it looks curved so you compare with a ruler to be sure and it is in fact straight.1

From the abandoned university my first dev project came from the course of programming 1(C as language).
I had to implement a robot that moves inside any matrix like map following both specified rules and random moves, and had to reach sooner or later the exit place of the room.
At first I was overwhelmed by the task at hand, then I had to calm myself and start hacking around to get any idea on how to even understand what's required to get to that point.
It obsessed me for the whole first 2 weeks, but the progress was quiet steady.
Then I hit a fundamental problem of state and movement of the robot... And, as always, the best thing to do at this point is to simply detach your attention from the issue|project.
In the same day my mind asynchronously bursted a solution to my problem, and after some time I came back to the project and accomplished it with 100% of the requirements met 😁
This is what it looked like in the console(minified here):
3333333
3000003
3000003
3003003
3003003
4003023
3333333
Guess which is which 😉2 -
Focus? Everything.. Downside? Not enough time to get good at everything. It depresses me. I see a language and framework and I Wana learn it and use it but I don't have the time cause I'm too busy coding on another platform. This makes me sad. I wish it were the matrix and I could download all languages syntax and apis into my brain so I could spend less time learning and more time making something significant. Okay okay, my focus is Java/Android with a dash of web

Electronic companies nowadays are no different than ranchers that force their slaves to earn money to buy new stuff cause people can’t repair old electronics or fix software bugs cause it’s not theirs or it’s not maintained and source code is not existent.
Damn you software and hardware corporations.
You tell everyone that you care about environment, yet you don’t fucking support your software and hardware as long as people use it. When you stop support you don’t make everything open source but keep it on your private repositories as intellectual property and fuck your clients.
Literally all electronics and software should be mandatory made open source to the people who purchased product so they can use it as long as they want not as long as corporate assholes want. This is insane law that is splitting our world and making it burn. If I could fix my laptop in nearby shop I wouldn’t have to purchase new one.
If it won’t change we will end up with <10 corporations that would rule world economy, everyone who will work for those corporations will be rich and happy and everyone else will be poor and unhappy . Mind me if this is not already happening and this planet slowly becomes Elysium movie nightmare.
Stop buying new stuff you stupid people cause this make things worse.
If it won’t change in 10 or so years there will be connected to cloud robots all over the world guarding us and some dick shit rich John Conor kid will hack them to exterminate humans by executing order 66. After that there will be big power outage that will put us into the role of battery and we would be closed in the barrel full of pink shit connected to matrix.
Get me out of here you asshole.1 -
Exploring dedekinds and kronecker products (script at - https://pastebin.com/dDuT3dTp)
and the thing I immediately notice, if you output the matrix is that it is a lower triangular matrix. I don't know a lot about the kronecker or matrices in general, but if dedekinds can be generated in this manner, shouldn't some standard approaches like back substitution or forward substitution be applicable here or am I off in left field on this?6 -
So at my school, the first 10 minutes of school is like when we can do whatever we want. Earlier in the morning i had been making a nodejs password manager thing just so i could try some things out. It also used bash so i could make it like a cli. I was debugging because my database viewer said that the table was empty but for whatever reason it still worked when i put things in it. So i had the db viewer open and terminal open and the teacher comes along."Woah are you like hacking a server" he said. Everybody around me started staring at me. I told him no im not. A couple minutes later he comes around again. The db viewer was closed and i was just in terminal trying to see if some changes worked. He said "Is this like the matrix or something???". I remembered i had a cmatrix package thing installed. I ran it. W O A H everybody around we was like. Luckily most people knew that
1. It wasnt hacking
2. I dont do hacking
3. I was doing it as a joke.
Although he must of been thinking that i was like a hardcore hacker in his class. Was weird and funny.2 -
So I was writing some C code, pretty simple code. I had to pass a matrix to a function. The matrix had been globally defined as arr[100][100]. But the actual size of the matrix was stored in 2 vars m, n. Now when defining the function if I do like this:
void fun(int a[][n])
The code doesn't work as expected but when defined as:
void fun(int a[][100])
Works perfectly.
I have no idea why this is happening, any insight will be very helpful.5 -
You know how the machine learning systems are in the news (and Ted talks, tech blogs, etc.) lately over how they're becoming blackbox logic machines, creating feedback loops that amply things like racism on YouTube, for example. Well, what might the ML/AI systems be doing with our code repositories? Maybe not so much yet, I don't know. But let's imagine. Do you think it's probably less worrisome? At first I didn't see as much harm potential, there's not really racist code, terrorist code, or code that makes people violence prone (okay, not entirely true...), but if you imagine the possibility that someone might use code repositories to create applications that modify code, or is capable of making new programs, or just finding and squishing bugs in code algorithmically, well then you have a system that could arguably start to get a little out of control! What if in squashing code bugs it decides the most prevalent bugs are from code that takes user input (just one of potentially infinite examples). Remember though, it's a blackbox of sorts and this is just one of possibly millions of code patterns it's finding troublesome, and most importantly it's happening slowly (at first). Just like how these ML forces are changing Google and YouTube algorithms so slowly that many don't notice the changes; this would presumably be similar and so it may not be as obvious as one would think. So anyways, 'it' starts refactoring code that takes user input into something 'safer'. Great! But what does this mean? Not for this specific example really, but this concept of blackbox ML/AI solutions to problems we didn't realize we had, what does a future with this stuff look like (Matrix jokes aside)? Well, I could go on all day with imaginative ideas... But talking to myself isn't so productive, let's start a fun community discussion here! Join in if you find this topic as interesting as I do! :)
Note: if you decide to post something like "SNN have made this problem...", or other technical jargan please explain it as clearly as possible. As the great Richard Feynman once said, the best way to show you understand a thing is to be able to explain it clearly to others who don't understand it... Or something like that ;)3 -
The Code Abyss Beckons! 🤯
Hey fellow devs, brace yourselves for a wild ride into the chaotic realm of code confessions and debugging dramas! 🎢💻
So, here I am, standing at the precipice of my latest coding adventure, armed with a keyboard and a questionable amount of caffeine. 🚨☕
Today's quest involves unraveling the mysteries of a legacy code that seems to have been written in a language only decipherable by ancient coding sages. 😱📜
As I navigate through the nested loops of confusion and dance with the dragons of runtime errors, I can't help but wonder: Is this what the Matrix feels like for developers? 🕵️♂️💊
In the midst of my debugging odyssey, I stumbled upon a comment in the code that simply said, "// Abandon hope, all ye who enter here." 🏴☠️📛 Well, isn't that reassuring?
And then there's the moment when you finally fix that elusive bug, and you feel like you've just tamed a mythical creature. 🦄✨ Victory dance, anyone? 💃🕺
But let's not forget the rubber duck sitting on my desk, patiently listening to my monologues about algorithms and existential coding crises. 🦆🗣️
So, dear coding comrades, how's your journey through the code abyss going? Any epic wins or facepalming fails to share? Let the rants flow like a river of improperly closed tags! 🌊🚫
May your semicolons be where they should and your documentation be ever truthful. Happy coding, and may your merge conflicts be swift and painless! 🌈🤞

I have decided that massive natural selection events are a thing with humans. When resources appear to be getting low a group of people will prepare and wipe out a large portion of consumers. The most straight forward way is to create a crisis and then offer the "only" solution. Make that solution a weapon and you are done. The masses gladly accept the solution. At all times appear benevolent. Silence dissenting voices swiftly. Make the dissenters look like nutters and publicly humiliate them and apply labels to them. Labels are effective because it creates pariahs. People like to not be singled out and called names.
What do you end up with? People who distrust government and the institutions. I don't know how this benefits the orchestrators (how to spell) of the genocide. Perhaps if the numbers are small enough they can just be rounded up and killed by force rather than coercion.
I get the feeling this approach has been used in the past. Like it has been at least tested on smaller scales. Maybe even on past civilizations. Did we learn to do this from space visitors? I wonder.
2021 has certainly been an interesting year. I used to think people were just stupid. This year has confirmed that for me. But I am not sure stupid is the right word. They are certainly book smart. Maybe naive is a better word. I pray and hope 2022 turns out better for people. Maybe they start seeing signs they have been lied to by people they trust. Maybe not. When you are in the matrix it is hard to see through the facade. The matrix feels very real, until it doesn't.
Dev Goal?: To not be murdered by the matrix.6 -
Let's say I take a matrix of high entropy random numbers (call it matrix J), and encode a problem into those numbers (represented as some integers which in turn represent some operations and data).
And then I generate *another* high entropy random number matrix (call it matrix K). As I do this I measure the Pearson's correlation coefficient between J (before encoding the problem into it, call Jb), and K, and the correlation between J (after encoding, let's call it Ja) and K.
I stop at some predetermined satisfactory correlation level, let's say > 0.5 or < -0.5
I do this till Ja is highly correlated with some sample of K, and Jb's correlation with K is close to 0.
Would the random numbers in K then represent, in some way, the data/problem encoded in Ja? Or is it merely a correlation?
Keep in mind K has no direct connection to J, Ja, or Jb, we're only looking for a matrix of high entropy random numbers that indicated a correlation to J and its data.
I say "high entropy", it would be trivial to generate random numbers with a PRNG that are highly correlated simply by virtue of the algorithm that generated them.12 -
