Hi, I am a Javascript apprentice. Can you help me with my project?
- Sure! What do you need?
Oh, it’s very simple, I just want to make a static webpage that shows a clock with the real time.
- Wait, why static? Why not dynamic?
I don’t know, I guess it’ll be easier.
- Well, maybe, but that’s boring, and if that’s boring you are not going to put in time, and if you’re not going to put in time, it’s going to be harder; so it’s better to start with something harder in order to make it easier.
You know that doesn’t make sense right?
- When you learn Javascript you’ll get it.
Okay, so I want to parse this date first to make the clock be universal for all the regions.
- You’re not going to do that by yourself right? You know what they say, don’t repeat yourself!
But it’s just two lines.
- Don’t reinvent the wheel!
Literally, Javascript has a built in library for t...
- One component per file!
I’m lost.
- It happens, and you’ll get lost managing your files as well. You should use Webpack or Browserify for managing your modules.
Doesn’t Javascript include that already?
- Yes, but some people still have previous versions of ECMAScript, so it wouldn’t be compatible.
What’s ECMAScript?
- Javascript
Why is it called ECMAScript then?
- It’s called both ways. Anyways, after you install Webpack to manage your modules, you still need a module and dependency manager, such as bower, or node package manager or yarn.
What does that have to do with my page?
- So you can install AngularJS.
What’s AngularJS?
- A Javascript framework that allows you to do complex stuff easily, such as two way data binding!
Oh, that’s great, so if I modify one sentence on a part of the page, it will automatically refresh the other part of the page which is related to the first one and viceversa?
- Exactly! Except two way data binding is not recommended, since you don’t want child components to edit the parent components of your app.
Then why make two way data binding in the first place?
- It’s backed up by Google. You just don’t get it do you?
I have installed AngularJS now, but it seems I have to redefine something called a... directive?
- AngularJS is old now, you should start using Angular, aka Angular 2.
But it’s the same name... wtf! Only 3 minutes have passed since we started talking, how are they in Angular 2 already?
- You mean 3.
2.
- 3.
4?
- 5.
6?
- Exactly.
Okay, I now know Angular 6.0, and use a component based architecture using only a one way data binding, I have read and started using the Design Patterns already described to solve my problem without reinventing the wheel using libraries such as lodash and D3 for a world map visualization of my clock as well as moment to parse the dates correctly. I also used ECMAScript 6 with Babel to secure backwards compatibility.
- That’s good.
Really?
- Yes, except you didn’t concatenate your html into templates that can be under a super Javascript file which can, then, be concatenated along all your Javascript files and finally be minimized in order to reduce latency. And automate all that process using Gulp while testing every single unit of your code using Jasmine or protractor or just the Angular built in unit tester.
I did.
- But did you use TypeScript?37 -

*lunch break. In a table with 2 other co-workers*
Me: "I am going to quit today!"
Co-worker 1: "What? I am going to do that today too!"
Co-worker 2: "Are you serious? I was planning to do that too today!"
Me: "Holy cow! Let's do that today the three of us, but I am going last one. I want to see his face (our CEO)".
After couple of minutes and disagreement, we agreed to do that.
When I told him (I was the last to tell himm), he was sweating and his face was red. Started to throw offensive words towards me. I was expecting that and came prepared. BUT, in the middle of his words saying "I hire you because no one would hire you" etc, quietly and with a smile on my face, I interrupted him saying, "Look, is this going to take long? Because I gotta go somewhere and I am not in the mood to listen to you!"
He started to shake from that rage he had inside him. I know he wanted to punch me. But nothing happened.
I still remember his face like it was yesterday. :P
Epilogue:
My aunt's husband and him were best friends. He called him saying what happened. Of course, I was the one to blame. Since my parent knew what kind of guy he is, they told me "You did good for being quiet, not screaming and not acting like a child!"9 -
Only in computer science you'll find that root is on the top of the tree and that parent may kill it's child after its function is no longer needed.4

We had a Commodore64. My dad used to be an electrical engineer and had programs on it for calculations, but sometimes I was allowed to play games on it.
When my mother passed away (late 80s, I was 7), I closed up completely. I didn't speak, locked myself into my room, skipped school to read in the library. My dad was a lovely caring man, but he was suffering from a mental disease, so he couldn't really handle the situation either.
A few weeks after the funeral, on my birthday, the C64 was set up in my bedroom, with the "programmers reference guide" on my desk. I stayed up late every night to read it and try the examples, thought about those programs while in school. I memorized the addresses of the sound and sprite buffers, learnt how programs were managed in memory and stored on the casette.
I worked on my own games, got lost in the stories I was writing, mostly scifi/fantasy RPGs. I bought 2764 eproms and soldered custom cartridges so I could store my finished work safely.
When I was 12 my dad disappeared, was found, and hospitalized with lost memory. I slipped through the cracks of child protection, felt responsible to take care of the house and pay the bills. After a year I got picked up and placed in foster care in a strict Christian family who disallowed the use of computers.
I ran away when I was 13, rented a student apartment using my orphanage checks (about €800/m), got a bunch of new and recycled computers on which I installed Debian, and learnt many new programming languages (C/C++, Haskell, JS, PHP, etc). My apartment mates joked about the 12 CRT monitors in my room, but I loved playing around with experimental networking setups. I tried to keep a low profile and attended high school, often faking my dad's signatures.
After a little over a year I was picked up by child protection again. My dad was living on his own again, partly recovered, and in front of a judge he agreed to be provisory legal guardian, despite his condition. I was ruled to be legally an adult at the age of 15, and got to keep living in the student flat (nation-wide foster parent shortage played a role).
OK, so this sounds like a sobstory. It isn't. I fondly remember my mom, my dad is doing pretty well, enjoying his old age together with an nice woman in some communal landhouse place.
I had a bit of a downturn from age 18-22 or so, lots of drugs and partying. Maybe I just needed to do that. I never finished any school (not even high school), but managed to build a relatively good career. My mom was a biochemist and left me a lot of books, and I started out as lab analyst for a pharma company, later went into phytogenetics, then aerospace (QA/NDT), and later back to pure programming again.
Computers helped me through a tough childhood.
They awakened a passion for creative writing, for math, for science as a whole. I'm a bit messed up, a bit of a survivalist, but currently quite happy and content with my life.
I try to keep reminding people around me, especially those who have just become parents, that you might feel like your kids need a perfect childhood, worrying about social development, dragging them to soccer matches and expensive schools...
But the most important part is to just love them, even if (or especially when) life is harsh and imperfect. Show them you love them with small gestures, and give their dreams the chance to flourish using any of the little resources you have available.22 -
It finally hit me the other day.
I'm working on an IoT project for a late-stage ALS patient. The setup is that he has a tablet he controls with his eye movements, and he wants to be able to control furnishings in his room without relying on anyone else.
I set up a socket connection between his tablet and the Raspberry Pi. From there it was a simple matter of using GPIO to turn a lamp or fan on or off. I did the whole thing in C, even the socket programming on the Pi.
As I was finishing up the main control of the program on the Pi I realized that I need to be more certain of this than anything I've ever done before.
If something breaks, the client may be forced to go days without being able to turn his room light on, or his fan off.
Understand he is totally trapped in his own body so it's not like he can simply turn the fan off. The nursing staff are not particularly helpful and his wife is tied up a lot with work and their two small children so she can't spend all day every day doting on him.
Think of how annoying it is when you're trying to sleep and someone turns the light on in your room; now imagine you can't turn it off yourself, and it would take you about twenty minutes to tell someone to turn it off -- that is once you get their attention, again without being able to move any part of your body except your eyes.
As programmers and devs, it's a skill to do thorough testing and iron-out all the bugs. It is an entirely different experience when your client will be depending on what you're doing to drastically improve his quality of life, by being able to control his comfort level directly without relying on others -- that is, to do the simplest of tasks that we all take for granted.
Giving this man some independence back to his life is a huge honor; however, it carries the burden of knowing that I need to be damned confident in what I am doing, and that I have designed the system to recover from any catastrophe as quickly as possible.
In case you were wondering how I did it all: The Pi launches a wrapper for the socket connection on boot.
The wrapper launches the actual socket connection in a child process, then waits for it to exit. When the socket connection exits, the wrapper analyzes the cause for the exit.
If the socket connection exited safely -- by passing a special command from the tablet to the Pi -- then the wrapper exits the main function, which allows updating the Pi. If the socket connection exited unexpectedly, then the Pi reboots automatically -- which is the fastest way to return functionality and to safeguard against any resource leaks.
The socket program itself launches its own child process, which is an executable on the Pi. The data sent by the tablet is the name of the executable on the Pi. This allows a dynamic number of programs that can be controlled from the tablet, without having to reprogram the Pi, except for loding the executable onto it. If this child of the socket program fails, it will not disrupt its parent process, which is the socket program itself.13 -
"Who the heck is the parent of this child?" -
I ask to myself when a button doesn't position itself relative to its container div as expected..
:/
In the end, it looks as it's supposed to, but the way it's done is just bad

Rest In Peace My Dad. now he is going to follow my uncle. the best two person and developers in my world. as a lone survivor, your memory will continue to be remembered propagate through my life.
for fellow devRanters, Always love your family more when they're still in your side. doesn't matter how harsh, how bad they are; you can always find the meaning, the values life will give you, and that will be the best presents your parent will give you. Always. stay creative, they will be proud.

fork() can fail: this is important
Ah, fork(). The way processes make more processes. Well, one of them, anyway. It seems I have another story to tell about it.
It can fail. Got that? Are you taking this seriously? You should. fork can fail. Just like malloc, it can fail. Neither of them fail often, but when they do, you can't just ignore it. You have to do something intelligent about it.
People seem to know that fork will return 0 if you're the child and some positive number if you're the parent -- that number is the child's pid. They sock this number away and then use it later.
Guess what happens when you don't test for failure? Yep, that's right, you probably treat "-1" (fork's error result) as a pid.
That's the beginning of the pain. The true pain comes later when it's time to send a signal. Maybe you want to shut down a child process.
Do you kill(pid, signal)? Maybe you do kill(pid, 9).
Do you know what happens when pid is -1? You really should. It's Important. Yes, with a capital I.
...
...
...
Here, I'll paste from the kill(2) man page on my Linux box.
If pid equals -1, then sig is sent to every process for which the calling process has permission to send signals, except for process 1 (init), ...
See that? Killing "pid -1" is equivalent to massacring every other process you are permitted to signal. If you're root, that's probably everything. You live and init lives, but that's it. Everything else is gone gone gone.
Do you have code which manages processes? Have you ever found a machine totally dead except for the text console getty/login (which are respawned by init, naturally) and the process manager? Did you blame the oomkiller in the kernel?
It might not be the guilty party here. Go see if you killed -1.
Unix: just enough potholes and bear traps to keep an entire valley going.

Adding borders to HTML elements? Nah.
I put them in a parent element with a background color, then add margin to the child.7 -
All love to Android community.
I made a parental control app where parent can control child phone using SMS. Also I published research paper on it and gonna do presentation on March 23.19 -
> Root struggles with her ticket
> Boss struggles too
> Also: random thoughts about this job
I've been sick lately, and it's the kind of sick where I'm exhausted all day, every day (infuriatingly, except at night). While tired, I can't think, so I can't really work, but I'm during my probationary period at work, so I've still been doing my best -- which, honestly, is pretty shit right now.
My current project involves legal agreements, and changing agent authorization methods (written, telephone recording, or letting the user click a link). Each of these, and depending on the type of transaction, requires a different legal agreement. And the logic and structure surrounding these is intricate and confusing to follow. I've been struggling through this and the project's ever-expanding scope for weeks, and specifically the agreements logic for the past few days. I've felt embarrassed and guilty for making so little progress, and that (and a bunch of other things) are making me depressed.
Today, I finally gave up and asked my boss for help. We had an hour and a half call where we worked through it together (at 6pm...). Despite having written quite a bit of the code and tests, he was often saying things like "How is this not working? This doesn't make any sense." So I don't feel quite so bad now.
I knew the code was complex and sprawling and unintuitive, but seeing one of its authors struggling too was really cathartic.
On an unrelated note, I asked the most senior dev (a Macintosh Lisa dev) why everything was using strings instead of symbols (in Rails) since symbols are much faster. That got him looking into the benchmarks, and he found that symbols are about twice as fast (for his minimal test, anyway), and he suggested we switch to those. His word is gold; mine is ignorable. kind of annoying. but anyway, he further went into optimizing the lookup of a giant array of strings, and discovered bsearch. (it's a divide-and-conquer lookup). and here I am wondering why they didn't implement it that way to begin with. 🙄
I don't think I'm learning much here, except how to work with a "mature" codebase. To take a page from @Rutee07, I think "mature" here means the same as in porn: not something you ever want ot see or think about.
I mean, I'm learning other things, too, like how to delegate methods from one model to another, but I have yet to see why you would want to. Every use of it I've explored thus far has just complicated things, like delegating methods on a child of a 1:n relation to the parent. Which child? How does that work? No bloody clue! but it does, somehow, after I copy/pasted a bunch of esoteric legacy bs and fussed with it enough.
I feel like once I get a good grasp of the various payment wrappers, verification/anti-fraud integration, and per-business fraud rules I'll have learned most of what they can offer. Specifically those because I had written a baby version of them at a previous job (Hell), and was trying to architect exactly what this company already has built.
I like a few things about this company. I like my boss. I like the remote work. I like the code reviews. I like the pay. I like the office and some socializing twice a year.
But I don't like the codebase. at all. and I don't have any friends here. My boss is friendly, but he's not a friend. I feel like my last boss (both bosses) were, or could have been if I was more social. But here? I feel alone. I'm assigned work, and my boss is friendly when talking about work, but that's all he's there for. Out of the two female devs I work with, one basically just ignores me, and the other only ever talks about work in ways I can barely understand, and she's a little pushy, and just... really irritating. The "senior" devs (in quotes because they're honestly not amazing) just don't have time, which i understand. but at the same time... i don't have *anyone* to talk to. It really sucks.
I'm not happy here.
I miss my last job.
But the reason I left that one is because this job allows me to move and work remotely. I got a counter-offer from them exactly matching my current job, sans the code reviews. but we haven't moved yet. and if I leave and go back there without having moved, it'll look like i just abandoned them. and that's the last thing I want them to think.
So, I'm stuck here for awhile.
not that it's a bad thing, but i'm feeling overwhelmed and stressed. and it's just not a good fit. but maybe I'll actually start learning things. and I suppose that's also why I took the job.
So, ever onward, I guess.
It would just be nice if I could take some of the happy along with me.7 -
Hey look, npm broke my project again. Surprise!
Code and dependencies on my local machine, all untouched for a couple of weeks, no longer works. I've no idea how it even managed that.
Oh, and `npm update` crashes.
eventually solved by upgrading npm and running `npm update --depth 500` because some arbitrary child dependencies changed without updating the parent packages, ofc. on my local machine. without me having run `npm update` for about a month.
because of course that makes sense.
Second time in two months, too.
isn't npm great?3 -
When my idiot technical lead on the client’s floor (where everyone could hear him), “corrected” me in public telling me I should never use parent/child classes and override a method. Instead just use lots of if else statements in the one.
Not just is he a moron, but sounds like he knows what he is talking about if you are a client who knows nothing about coding. So I look like an idiot to our customers and he sounds smart... when it’s the other way around.
And HOW DARE you criticize anyone, even if it is warranted, in public in front of clients. You go in an office and close a door.6 -
Introducing a new javascript functionality:
Relation operators
These help you determine if object is related to other object and in which way (parent, child)
In screenshot a demonstration done on numbers
1 -
I am much too tired to go into details, probably because I left the office at 11:15pm, but I finally finished a feature. It doesn't even sound like a particularly large or complicated feature. It sounds like a simple, 1-2 day feature until you look at it closely.
It took me an entire fucking week. and all the while I was coaching a junior dev who had just picked up Rails and was building something very similar.
It's the model, controller, and UI for creating a parent object along with 0-n child objects, with default children suggestions, a fancy ui including the ability to dynamically add/remove children via buttons. and have the entire happy family save nicely and atomically on the backend. Plus a detailed-but-simple listing for non-technicals including some absolutely nontrivial css acrobatics.
After getting about 90% of everything built and working and beautiful, I learned that Rails does quite a bit of this for you, through `accepts_nested_params_for :collection`. But that requires very specific form input namespacing, and building that out correctly is flipping difficult. It's not like I could find good examples anywhere, either. I looked for hours. I finally found a rails tutorial vide linked from a comment on a SO answer from five years ago, and mashed its oversimplified and dated examples with the newer documentation, and worked around the issues that of course arose from that disasterous paring.
like.
I needed to store a template of the child object markup somewhere, yeah? The video had me trying to store all of the markup in a `data-fields=" "` attrib. wth? I tried storing it as a string and injecting it into javascript, but that didn't work either. parsing errors! yay! good job, you two.
So I ended up storing the markup (rendered from a rails partial) in an html comment of all things, and pulling the markup out of the comment and gsubbing its IDs on document load. This has the annoying effect of preventing me from using html comments in that partial (not that i really use them anyway, but.)
Just.
Every step of the way on building this was another mountain climb.
* singular vs plural naming and routing, and named routes. and dealing with issues arising from existing incorrect pluralization.
* reverse polymorphic relation (child -> x parent)
* The testing suite is incompatible with the new rails6. There is no fix. None. I checked. Nope. Not happening.
* Rails6 randomly and constantly crashes and/or caches random things (including arbitrary code changes) in development mode (and only development mode) when working with multiple databases.
* nested form builders
* styling a fucking checkbox
* Making that checkbox (rather, its label and container div) into a sexy animated slider
* passing data and locals to and between partials
* misleading documentation
* building the partials to be self-contained and reusable
* coercing form builders into namespacing nested html inputs the way Rails expects
* input namespacing redux, now with nested form builders too!
* Figuring out how to generate markup for an empty child when I'm no longer rendering the children myself
* Figuring out where the fuck to put the blank child template markup so it's accessible, has the right namespacing, and is not submitted with everything else
* Figuring out how the fuck to read an html comment with JS
* nested strong params
* nested strong params
* nested fucking strong params
* caching parsed children's data on parent when the whole thing is bloody atomic.
* Converting datetimes from/to milliseconds on save/load
* CSS and bootstrap collisions
* CSS and bootstrap stupidity
* Reinventing the entire multi-child / nested params / atomic creating/updating/deleting feature on my own before discovering Rails can do that for you.
Just.
I am so glad it's working.
I don't even feel relieved. I just feel exhausted.
But it's done.
finally.
and it's done well. It's all self-contained and reusable, it's easy to read, has separate styling and reusable partials, etc. It's a two line copy/paste drop-in for any other model that needs it. Two lines and it just works, and even tells you if you screwed up.
I'm incredibly proud of everything that went into this.
But mostly I'm just incredibly tired.
Time for some well-deserved sleep.7 -
Seriously does this master/slave bullshit actually affect everyone here?
From what I’ve seen it’s just a fucking idea / suggestion not a full blown change set being implemented.
Stop fucking over reacting to bubble wrap nonsense, if you want to call it a master/slave relationship then call it a fucking master/slave relationship and be done with it, if this really offends you or you believe political correctness is needed here, go call it something else, at the end of the day it’s still going to be the same thing, just called something else.9 -
Fun Fact: Did you know that git clone starts a child process for downloading the repo but the parent process terminates, therefore working in an asynchrone way so &&-ing the next instruction, which might rely on those files, won't help you?
Well now you know, and so do I.
Fornicating piece of excrement, what a fun afternoon.17 -
I am not a front end developer. Don't have the skill set, but I am learning. Work assigns me an "easy" task of modifying someone else's angular code(with all those <div> tags) to change some functionality. If it was well formatted, easy shit.
WHY THE FUCK DID THE PREVIOUS FUCKER INDENT LIKE THEY HATE ME? PARENT TAGS ARE FARTHER OUT THAN CHILDREN TAGS. SOME OF THE TAGS ARE 10 TABS FROM THE LEFT, WHILE THEIR CHILD IS ONLY 2. IN ADDITION, ALL THEIR CODE IS COPY PASTED FROM OTHER FILES, REFERENCES CONTROLLERS FROM OTHER PARTS OF THE CODE IT DOESNT NEED!
I am tempted to kill it with fire, find the person who wrote it(on a different continent), kill them, and then rewrite the whole thing in a language I am still learning. FUCK!2 -
Yay! I got my head wrapped around Vue3 parent / child components and fed the whole thing JSON data loaded via Axios. A small feat perhaps, but it just feels great to still "get" stuff when learning becomes harder as I get older.4

So I'm writing some multithreaded shit in C that is supposed to work cross-platform. MingW has Posix threads for Windows, so that saved already half of the platform dependency. The other half was that these threads need to run external programs.
Well, there's system(), right? Uhm yes, but it sucks. It's incredibly slow on Windows, and it looks like you can have only one system() call ongoing at the same time. Which kinda defeats the multithreaded driver. Ok, but there's CreateProcessA(), and that doesn't suck.
Fine, now for Linux. The fork/exec hack is quite ugly, but it works and is even fast. Just never use fork() without immediate exec(). First try under Cygwin... crap I fork bombed my system! What is this shit? Ah I fucked up the path names so that the external executable couldn't be run.
Lesson learnt: put an exit() right after the exec() in the path for child process. Should never be reached, but if it goes there, the exit() at least prevents a fork bomb.
Well yeah, sort of works under Cygwin, but only with up to 3 threads. Beyond that, it seems like fork() at some point gives two processes the same PID, and then shit hangs.
Even slapping a mutex around the fork and releasing it only in the parent process didn't help. Fork in Cygwin is like a fork in the ass. posix_spawn() should work better because it can be mapped more easily to the Windows model, but still no dice.
OK, testing under real Linux. Yeah, no issues with that one! But instead, I get some obscure "free(): invalid size" abort. What the fuck would that even mean?! Checking my free() calls: all fine.
Time to fire up GDB in the terminal! Put a catch on the abort signal, mh got just hex data. Shit I forgot to compile with -O0 and -g. Next try. Backtrace shows the full call trace, back to the originating line in my program - which is fclose() on a file.
Ahhh I remember! Under Linux, fclosing a file that is already closed makes the program crash. So probably I was closing it twice. Checking back.. yeah that's where it was.
Shit runs fast on several cores now!8 -
For about 3x years now, we have had 3x generic work email addresses that are used as microsoft accounts for office 2016 licenses.
(The company is dragging its heels on getting office 365 so MS like to make our lives hell.)
Suddenly we can’t get office updates... and when we sign in to see why, it says that because we are apparently only 3 years old we need our parents permission to use the account or we’ll lose access by September.
Never were we forced to enter a DOB when setting the accounts up!!! So it used the account setup date instead.
It turns out that we can’t change our DOB ourselves, as we are a ‘child’ and need a parents permission.
Fine.
I access my personal account and follow the instructions to add the 3x email addresses as my children so i can change the DOB.
‘Ha ha’ i hear microsoft saying, ‘it doesn’t work that way!!’
No, In order for the parent to verify their child’s identity, they are charged 0.50c per child!
Wtf!!
Doesn’t cost a lot but come on Microsoft!!
It’s that, or submit ID, which obviously wont work for a generic support@ email address like we have.
So annoying and we don’t know what to do.
Wonder how much MS are making out of this...2 -
When I asked to Experienced Senior about cherry pick command in git.

But Cherry Pick, He did not pick for explain. 😡4 -
Master/Slave
Fuck you guys. Honestly most of the rants i've read concerning python and their abolishme t of sait terms where fucking butthurt. "What virgin suggested this", "people shouldn't be offended, it's just a name" and so on.
I do agree with every one saying a name shouldn't matter (readability is a different story! However parent/child or producer/consumer IMHO preserve that). So why are you fucking offended when it is changed to parent/child or produver/consumer? Does it affect you in any way? You know there's the `sed` command, plus IntelliJ (and most other IDEs) have a quite good support for renaming/refactoring stuff.
By reacting this way, by beeing offended all you do is proving the point. Words can offend people. I personally don't care how it's called. So far I always used master/slave and didn't think twice about it. But then again if someone of my coworkers or friends would feel threatened by these words, I try to avoid them. Naming diesn't matter to me, nor the compiler. So fuck, if it makes people happy or feeling save then lets change it.
What the fuck do you gain by sticking to those terms anyways?18 -
So, first a bit of background:
We've got a parent class, owned by another team, and two child classes, owned by my team. One of the children is unused. (Already sounds bullshit right.)
On to the story:
6 months ago, I had to modify one of the children (add new functionality).
I try to modify the base class to add it, the senior dev in charge says "no, just add it on the child". So I do, then merge it in.
Yesterday I wake up to a high priority bug. Turns out the senior guy wants to add another child class, and wants the functionality I put in my class on the base class.
Even commented on my PR from 6 months ago asking why I didn't do that.
The fucker opened up a high priority issue assigned to me, asking ME TO DO THE CHANGE I WANTED TO DO 6 MONTHS AGO THAT HE SAID NO TO.
Fuck this shit. I have a meeting with him and my boss in an hour. My boss is pissed, I hope he tells the other guy to go fuxk himself and do the change himself.14 -
That's it. I'm fucking retarded. I'm just so fucking retarded. I'm so fucking supid, it makes me wonder why do I even keep trying. I'm not sure I even have the energy in my fingers to keep typing this stupid rant.
I've been banging my head against this stupid fucking issue for A WEEK. Digging into the documentation, trying different library versions, trying to move stuff around even if it didn't make sense, trying to use different approaches because maybe I was missing something, or maybe I didn't understand some concept.
Surely spawning a child function from a parent can't be that hard, right?
Nothing.
Even tried it on a different OS - who knows, maybe it's Windows doing some if its magic fuckery?
Still nothing.

A taxi booking platform to support functioning B2B taxing booking company that was turning over 15 million per year.
It offered portals for B2B and B2C. Rather simple concept.
Business or client raise a booking, booking is submitted to a 3rd party taxi firm we manage the booking throughout its lifetime for the client.
We had an existing legacy product in place that needed redeveloping.
Management sunk many, many millions of pounds into the project, it never lunch and teh company was sold off twice will extreme losses each time. First sale was in the millions and the second was for 500k.
This was a result of poor technical choices made by past lead developers and extremely poor choice of management who cared more for managing their reputation as they were self aware of how much knowledge they lacked.
The technical aspect of the company was created a child company of the parent. This child company was responsible for the downfall of the parent which was functioning well and making a profit.
The company as a whole has since been liquidated thanks to that project. Many out of a job.
I jumped ship after 8 months as I couldn't continue to work with the crazy management. By crazy I mean they should have been in a tincan.3 -
So I am interning at this company, and I am Coding in Go.
Now I don't have much exp with go so I'm learning it, and all of my team is cool cause they also had to learn Go. Anyways I am just petty intern-dev so everyone and everything is cool.
Migrating from python to go is quite hard.
Unlearn, You must.
What I have imagined Go, to be is:
While python has this top down approach to inheritance and polymorphism, Go has bottom up approach.
In Python child classes are derived from parent class but In Go child classes create a parent class. (this might be totally wrong, but that's how I've imagined golang)
Go is static wrt dynamic python.
I have coded in C for 1.5 years then I switched to python, so I feel that am familiar with static typing. The path that lies ahead of me shouldn't be too hard.
I would like to take a step further and say that Golang is C, but with modern syntax/semantics. It derives many of its features from newer langs like js, Python, etc while being a compiled language which translated directly to machine code.
That's all 😊
My team members are really great and supportive, I am about 10 years younger than them but we still connect and sync.
Everything is Great, Life is Good ❤️2 -
Being a parent I've come to the conclusion that my "career" isn't a priority, my kid is.
Thats also because I'm at a position wherein i know that even with a non 100% effort towards work i can still get substantial results
I've been thinking now that I've come to this conclusion, would i want to raise my child in a way that she herself comes to a similar conclusion eventually. As in follow a career path, grow, become a parent and realise your priorities aren't the ones you always thought they were.
Or should I raise her to be focused on life and not try to make a mark in the world.. by focusing on the little things and not the grand picture.
Parents only comments are suggested here8 -
While parsing nodes in a graph.
In terms of readability and variable naming, how wrong (if at all) is to use:
1. broNode (for sibling nodes)
2. papaNode / mamaNode (for parent nodes)
3. babyNode (for child nodes)
I sincerely don't know how to review this PR7 -
We were having a 30 min discussion about differed tasks and how to kill children spawned by a specific parent if the so said parent is killed, and if in a situation where keeping a parent alive is irrelevant if a child fails, should the child kill the parent and the other children?
Also if a family of tasks spawned from the same parents were canceled, should should I just kill myself or do I take care of the others first?
Or should I concentrate on killing the tasks instead? Which one is easier?3 -
It’s actually been quite a fun day, after some ranting on one of our slack communities flutter channel, myself and my team realized we were in a really good place to give back.
We have been working on a large scale flutter application for about a year, phase 1 is about done and we at 11k LOC.
We have been doing a big push for testing over the last 2 months and are at about 50% coverage. The thing we realized is that is the 1 place flutter has fallen short with documentation.
Very little about what we learned for testing our code came out of a google search, or it came out of cobbling bits together from numerous searches and sources.
So we decided we are going to plan and host a virtual meetup to discuss what we have learned and hopefully teach a few people some useful things and hopefully also learn a few new things too.
In addition, and as it has a longer shelf life, we going to setup a medium publication for the company and start a series to cover small specific topics, specific use cases or scenarios that we had trouble with and solved.
Today I had my first thing to type out, had worked out how to test that a function that was passed into a widget was called. So the parent passes the child and onTap function but you are testing the child not the parent as the child is reusable...
Anyway, so with that idea I got hold of marketing for some assets, setup the publication and proceeded to type out 3 articles today, all nice short ones under 2 min reading time.
It really is nice to give back, it’s not like I am Remi smart and can go and write BLoC, but I am smart enough to figure shit out and type it up so that the next guy hopefully benefits from my brain bashing.6 -
Day 1 of a new semester in college. Our 50 yr old H.O.D is a guest lecturer of this new subject called "Industrial Management" (why its included in the syllabus of CSE degree i wonder) . As there were only 6 students , the guy went on like a drunkard telling life lessons :
1) only 20% of the people in a company are only working. Rest 80% of them are just using sugar coated words at the right place ; doing politics and taking credits of the others .
2) those 80% getting benefits are usually the bosses (and in his example, the senior deans and H.O.Ds buttering the administrative dept and director ) and the hardworking 20% are the Juniors or the new joiners ( and in his example, the latest recruited ,honest teachers. Makes sense why we have shitty teachers :/ ). They altogether make sucesses to the company(although its just those 20%hardworkers doing the actual job) . But at the time of salary everybody gets the benfit.
3) Its always perfect to throw blames at senior or junior. (explaining how a parent complaining about the poor study environment to director is made to think that it's only the fault of his own child. blames going from director to dean to HOD to teachers to your own child's mistakes.)
4) Being your boss's favourite is super important. He gave example as : 2 teachers meets him with 100% results and 100% reviews. One of them is a known asshole with 0 knowledge, who makes jokes and sexist comments during the class, gives free attendence and question papers before the exam{therefore 100%reviews} . But he is dean's great ass-licker . The other one is honest hard-working teacher with real reviews and results. So he says he shows their combine results to the director along with his own buttering and ass licking, gets a hike himself and permit to give hije to one junior teacher. And who would it give hike to? The ass licking asshole, because that's how it works. What about the honest teacher?what reply would he get? Simply, appreciations and sugar coated words : "thank you for working so hard. But you did not do anything new. You were only hired to DO hardwork and give good results"
( and i was like fuck? Like seriously? Because that is something resonating with what i once heard in my internship :"yeah you are developing nice and all good, but that's what you are expected to do. You were only hired to achieve results, and you did nothing new". So that's what we are missing? Ass licking?-_- )
5) He believed its important to "look working" than being "actually working" . Quoting an example from his days as a dev, he told a story about how he once worked on a project with deadline of 1 month . He was young and worked hard and in 2 days completed the complete project and accidentally reported success to boss instead of his seniors. The boss simply congratulated his team(seniors and him) and assigned them another project. Later that day , he got an ass-wipe scolding from his seniors that if he had kept his mouth shut, they would have simply watched movies and relax for next 15 days, and submit the project during the salary time to gain bonus attention.
He even gave his short mantra or principle for such situation "kaam ki fickar kar, fickar ka zickar kar, par kaam mat kar " (get worried and tensed about the work. Display your tention and worries to the world (esp bosses) . But don't work.)
And there were many other short stories like that.
Mann, i was about to shout " you corrupt asshole ", but one thing He just told us about the importance of being in boss's good books made me stop ( nd he is a fucking HOD, senior to teachers)
But hell he told some relatable truths. Make me sad about the job life.
Bloody Office politics :| -
Hm... Not a big follower on this issue but just a thought... at 3am...

After 2 days of trying to understand unclear requirements I got for a new project... I discover my boss wrote them....
From the description, it read like he flipped it around from what he actually wanted (there's a difference between parent-children and child-parent)
And he always gave me the feeling that he had gotten it from some business team so I spent 2 days trying to figure out who wrote these requirements so I could ask them.

I just styled something that appears to be an "parent" style change when a certain "child" was hovered.
Vanilla CSS. I think I've seen it all now.
My brain is spaghetti right now 🤪1 -
Working on a big project with lots of legacy code and terrible code. Full of jewels like this:
$('.form-item-to input').parent().removeClass('isOpen');
Man... .form-item-to IS the immediate, direct and only parent of the only input child!!! -
I can't convince my team that a good database model promotes a good API design and a good UI/UX experience.
Instead, I have to work with a ridiculous table setup.
Imagine, if you will, a table (table B) that references another table (table A) via a foreign key. The FK is a string in both tables. And table A only has one column, which is labeled as "name".
The schema i have to look at it kind of like this:
Table parent
Name varchar(10) primary key
Table child
Name varchar (10),
parent_name varchar(10),
Foreign key (parent_name) references parent (name)
Sorry if the syntax is wrong, a little frustrated having to look at it...
Am I crazy to want to change this table design? Am I missing something? I feel like I'm taking crazy pills, because this is just scratching the surface of the problems I have to deal with.7 -
my 3 year old youngest child just yelled 'hello world' but didn't told me if he echoed or printed it.

Okay c/c++ megaminds, I have a question about how something is generally designed that I feel like is too broad for SO or to be effectively Googled (though my Google-Jitsu may just be a tad weak, idk)
Lets say I have, for example, a simple graphical interface system where each widget/ control may have child controls. We could store it as a simple list/ array/ vector/ whatever - say Widget.children
Now these children could be added with a function like addChild(Widget*). This function would accept widgets allocated both on the stack and on the heap... but only widgets allocated on the heap would need to be freed.
My question is: on the destructor of the parent widget, how would it free all of its child widgets, if some are on the stack and some are on the heap and we don't know which is which...
And my broader question is what's the general design for this sort of thing? Should all items just be heap allocated always? Should it never be the responsibility of the parent widget to free the child widgets?9 -
Back in the days, i was on my way back home, after visiting my wife who brought our little son to life, it once blew my mind.
The terminology "inherit" is complete bullshit.
Why is that?
Because, a child isn't able to do anything the parents can, immediately.
It has to learn every single ability from it's parents or who knows else.
Maybe a kid won't be able to learn a specific ability from it's parents at all.
Furthermore, a child doesn't have a single parent.
There are always mom and dad.
Ok. Besides that, there is the option of a solo parentship, if a woman decides to breed based on frozen code ;) -
2 days (actually about 4 hours) of battling a stupid CSS grid arrange that wouldn't behave.
Turns out 1fr (aka fill parent) works unless the child is another grid. In that case it forgets and just stretches the freaking parent as if there was no rule whatsoever.
If you have problems with CSS grids, consider trying flattening the markup...3 -
Found out the database was missing a record from the parent table. The app hummed along perfectly, pulling all the data from child records.
TL;DR: This app uses the worst possible database form if everything you need is duplicated into all the child records every time.4 -
I must assume that whoever designed jinja2 was either on crack, or hadn’t used template systems before. This thing is too fucking complicated, and doesn’t make sense. From their docs:
“Jinja2 supports dynamic inheritance and does not distinguish between parent and child template as long as no extends tag is visited. While this leads to the surprising behavior that everything before the first extends tag including whitespace is printed out instead of being ignored, it can be used for a neat trick.”
My response: “I don’t give a fuck!! I need this fucking website to be fucking done already! I pass data into a fucking template engine, and the engine applies my fucking markdown!! This is bullshit!! Why am I still trying to understand your fucking nonsense?!? AGGJCDJVFD&@!?&@$?)@&!SHHHVBSHK!!!!!!”

Fuck you to hell you jinja fucker3 -
It's really hard to search in Google about how to kill children when parent is not waiting for them so the children won't become a zombie

Testing is important. Like when you test your server program that forks another program in the privacy of your home, only to discover you put the child code where the parent code should have gone and vice-versa.
You and your wife can have a laugh about it, instead of getting reamed out by the client or your boss for fork-bombing the server.
Sucks because it's still a stupid mistake, but at least I managed to minimize the amount of shit that would have otherwise landed on me. -
What's the fuckin point when a language makes you call the constructor of a parent class in the child class before you can use the inherited items?
Why do I need to call `super()` every time in my constructors? Why can't this be automatic?7 -
spending 2 hours to split LookAt rotation between two nested transforms where parent was supposed to only recieve the vertical axis rotation and the child the horizontal axis rotation. (unity3d)

I can't post a collab from the web client and I don't have a decent phone atm, anyways, this is an idea, tell me if you have any improvements or if you know of an implementation or would be interested in creating one.
A social network comment system that connects people across fields of interest and aids keeping relevant posts alive for a long time.
The basic principle is this: Every post may identify itself as a child to any number of other posts, or sections in other posts, which then act much like a bidirectional hyperlink between parent and child.
This leads to two unusual results:
1. that comments aren’t only added to posts, but specific paragraphs, sentences or even words.
2. that any comment may receive comments in much the same way the original post did, making comments identical to posts. (they could have their own pages and all).
This is in many ways like Reddit's infinite comment chains. The main difference is that here comments aren’t organized in trees but graphs, which makes it possible to connect related conversations from entirely different groups and times, resulting in a much more open yet concise discourse style with an increased persistence of topics. -

Is there a way to listen to child window events from a parent?

Trying to explain to (a more experienced) dev why it's not a god idea to do a exec( php '/var/www/xxx >> /dev/null) and then redirect the visitor.
The script is running a query that take some time and he want's to redirect the visitor and then fetch the result with jquery.
Tried to explain parent and child processes and pointed him in the direction with pipes and bakground process. After some discussion about forking and all the cons with that.
yes its PHP ;)
Gonna be exiting to see his next idea :S -
Why does it take so much effort to do a very simple thing in angular?
Here I am trying to create an observable that listens to two observables from parent and child. I have to subscribe to observable in parent and then convert @input value back to observable. Fuck angular

I been teaching someone python for a few day with 2-3 hour each day. It has been very pleasant to teach him programming since he have a goal in mind. He already know what kind of program we wanted to build.
He is a novice and not familiar with programming. It have been a good chance to see how the novice look at the python. I been given a chance to ask the answer like
"Why do we throw exception?" ,
"Why do we put define function at the top of the file and not at __main__?"
"Why do I need to use constructor?" ,
"Why should I call parent constructor in the child constructor?"
Here is the main question.
I have been wondering "should I teach him multi inheritance and the diamond problem?" I haven't been using multi inheritance for a while other than the exercise I done when I started programming and cannot think of the situation to use multi inheritance. I know in other language we use multi inheritance (kind of) regularly by extending multiple interface. I wanted to ask if multi inheritance is common in python.
Another question I have is how should I introduce him to gui programming in a simple manner? I am thinking of introduction him to the gui framework which haved WYSIWYG editor like "Remi"10 -
Just some figma improvements from the perspective of a new customer:
* Copy/paste is broken. If I want to make a change, I have to create a whole new
component. They recommend cmd+c/v for copypaste but as far as I can see it does nothing
* Needs to be an explicit component drawer button instead of hiding it under assets. Through me for a loop for a couple minutes.
* Empty textboxes shouldn't vanish because you happened to click in the wrong location
while setting your properties.
* Text should start big enough to actually see.
* "send to back/front", "hide item", "change transparency' all need to be prototype actions and more, give us access to object properties both by parent/sibling/child, and by
object id
* create a new frame based on a specified size is non-obvious and if you're creating
a lot of frames, what with copypaste being non-intuitive, it can become laborious.
This is especially so when you're copying frames in order to make minor changes and observe the differences side by side, instead of potentially destructive edits.
* I see no obvious way to manage transitions/animations between frames.
* The difference between frames and groups isn't sufficiently explained. The words
frame, groups, and layers all appear to new users to be used interchangeably, even
if they are distinct things.2 -
My journey along Java continues and so I have discovered something I didn't know before:
If a subclass tries to call a method on its parent which it has not overridden, then it will call the method as if you hadn't used the keyword 'super' (and I think it will try to find it in the classpath and SDK).
Example 1:
public class SuperParent {
public String test(){
return "SuperParent";
}
}
public class Parent extends SuperParent {
}
public class Child extends Parent {
public String testChild(){
return super.test(); // same effect as test();
}
}
public class TestInheritance {
public static void main(String[] args) {
System.out.println(new Child().test()); // returns "SuperParent"
}
}
Example 2: with getClass():
public class Parent {
@Override
public String toString(){
return super.getClass().getSimpleName();
}
}
public class Child extends Parent {
}
public class TestInheritance {
public static void main(String[] args) {
System.out.println(new Child()); // prints "Child"
}
}
This here is of course a special case: .getClass() will always return the class name of its caller, so naturally in this case it returns Child and not Parent.
You would expect it to return "Parent" since you use 'super' in the overridden toString() but it returns the Class name of the Child (then there's something in programming languages such lexical scope and execution scope, which I'm not sure if it applies here).
The solution for this example is of course .getSuperClass().
Inheritance isn't always straight-forward.

Why useImperativeHandle in React is bad?
I have component A. I have component B which is a child of A.
I have button in component A that should change how component B is displayed.
Usual approach is to set state in A, change it upon click and pass that state as flag via props to B.
But there is another approach via exposing ref to component B using forwardRef() + useImperativeHandle().
And then calling method that belongs to B from A. Like this: bRef.current.changeDisplay()

People on SoF and Docs say that the first way is preferrable. But no one explain why.

How broken is z-index implementation on Chrome?!
Almost an hour lost today, due to perfectly fine web code running on Firefox, but showing completely wrong z-order on Chrome.
The reason? I manually changed the z-index of a child and not the one from the parent DIV. (and I was only making the child z-order *higher* than everything else on screen, so I could drag it around)
Code now has a bunch of "// thanks Chrome!" to show due appreciation. Grrr....1 -

I am trying to write a program in c which forks a process and exec another program i wrote. I want to redirect output of child program to parent program then after getting that output parent will check some conditions and if they are true then it will resume child program and will do more stuff. I have successfully redirected output of child to parent using pipes then I wrote code which should be read in child program but it isn't getting read. I tried by passing pipe read and write ends as cmdline arguments to child program but it isn't reading. It is blocking at that particular point. Stuck for more than 5 hours at this. Can anyone help me here? Fml :-(
