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 -
“Fullstack dev continues to unleash his terror.”
We were in a meeting the other day discussing how we can integrate our React component with other existing systems easily — other React apps, Ionic, Angular, Vue and vanilla HTML.
All of a sudden, he opens his mouth.
Fullstack dev: So the thing is... it’s like...ummm... (he always starts after with these words. Always) since Ionic and Vue are both “angular-based”. It shouldn’t be a problem.
Me: excuse me! What do you mean vue is “angular-based”? What’s vue gotta do with angular?
Fullstack dev: You need angular installed to run vue apps and you have data binding in vue and in angular.
Me: (fuck me dead) I don’t know what that means, but I know what the Rock is cookin’. (My exact words in the meeting)
They flew him in from India and they keep extending his stay. He’s been working on the project for 2+ years now.
More to come!26 -
Imagine, you get employed to restart a software project. They tell you, but first we should get this old software running. It's 'almost finished'.
A WPF application running on a soc ... with a 10" touchscreen on win10, a embedded solution, to control a machine, which has been already sold to customers. You think, 'ok, WTF, why is this happening'?
You open the old software - it crashes immediately.
You open it again but now you are so clever to copy an xml file manually to the root folder and see all of it's beauty for the first time (after waiting for the freezed GUI to become responsive):
* a static logo of the company, taking about 1/5 of the screen horizontally
* circle buttons
* and a navigation interface made in the early 90's from a child
So you click a button and - it crashes.
You restart the software.
You type something like 'abc' in a 'numberfield' - it crashes.
OK ... now you start the application again and try to navigate to another view - and? of course it crashes again.
You are excited to finally open the source code of this masterpiece.
Thank you jesus, the 'dev' who did this, didn't forget to write every business logic in the code behind of the views.
He even managed to put 6 views into one and put all their logig in the code behind!
He doesn't know what binding is or a pattern like MVVM.
But hey, there is also no validation of anything, not even checks for null.
He was so clever to use the GUI as his place to save data and there is a lot of parsing going on here, every time a value changes.
A thread must be something he never heard about - so thats why the GUI always freezes.
You tell them: It would be faster to rewrite the whole thing, because you wouldn't call it even an alpha. Nobody listenes.
Time passes by, new features must be implemented in this abomination, you try to make the cripple walk and everyone keeps asking: 'When we can start the new software?' and the guy who wrote this piece of shit in the first place, tries to give you good advice in coding and is telling you again: 'It was almost finished.' *facepalm*
And you? You would like to do him and humanity a big favour by hiting him hard in the face and breaking his hands, so he can never lay a hand on any keyboard again, to produce something no one serious would ever call code.4 -
VueJS FTW!
Today I realised I've been a fucking idiot.
For the last few years I have familiarized myself with libraries like React, VueJS, Preact etc.
All while playing around on my own side projects but when it came to doing actual work (perhaps from a lack of confidence/working experience with them) I always reverted to vanilla js or jQuery because I convinced myself it wasn't the `right` use case or `the project was too simple or small`.
I WAS AN IDIOT.
The below screenshot is a prototype of a n invoicing tool I needed to write which uses VueJS and is implemented in 50 beautiful, clean, maintainable loc. Combined with TypeScript it is a dream - never did I think I would see the day where I could grab an inputs numerical value without prepending the variable with + so I don't end up concatenating them as strings.
If your like me and haven't started using some kind of data binding view framework stop procrastinating and just do it. I feel like I wasted a large chunk of my life clinging onto my old ways.

Me and my developer friend worked with my ex-colleague with this fitness directory website because he promised to give us {{ thisAmount }} upon the {{ completionDate }}.
He was my friend and I trusted him.
It took me weeks of sleepless nights building the project. I had a full-time job that time, and I worked on the project during evenings. All went well, and as we reach the {{ completionDate }}, the demo site is already up and running.
A week before the {{ completionDate }}, he hired his new wife as the COO of the startup. It was cool, she keep noticing things on the site which shouldn't be there, and keeps on suggesting sections that has to be there. I was okay with it, until I realized that we are already a month late with the deadline.
Every single hour, I get a message from them like, "it's not working", "when can you finish this feature?", blah blah blah.. and so on.
I got frustrated.
"I want my fucking life back", I told them. No one cared about the {{ completionDate }}, the sleepless zombies they are working with and our payment. They keep on coming up with this "amazing" ass features, and now they are not paying because they said "it's not complete".
Idiot enough to trust a friend. I was unprotected, there was no legal-binding document that states their obligation to pay.
My dev friend and I handed over the project to this web development company which they prefer, and kept a backdoor on the application.
I kind of moved on with the payment issue after a month. But without their knowledge, I kept an eye on the progress and made sure that I still have the access to their server, DNS, etc..
BUT when they announced the official launch on social media, I realized that I was on the wrong train the whole time.
They switched to a different server.
They thanked all the people involved with the project via social media, EXCEPT me and my coding partner who originally built the site from ground up. A little "thank you" note from them will make us feel a little better. But, never happened.
I checked up the site and it was rewritten from originally Laravel 5 to CodeIgniter 1. That is like shifting from a luxury yacht where you can bang some hot chicks, to a row boat where your left hand is holding the paddle whilst your right hand is wanking yourself.
I almost ran out of bullets.
Luckily, CodeIgniter 1 was prone to SQLi by default.
I was able to get the administrator password in plain text and fucked with their data. But that didn't make me feel better because other people's info are involved.
So, I looked for something else to screw with. What I found? A message with the credit card details.
Finally, a chance to do something good for humanity. I just donated a few thousand dollars to different charity websites.3 -
I quite like Unity.
It's a good engine, BUT....
I despise doing UI in it, it's just so tedious to make everything work and show up.
In the past I didn't mind but then I learned about XAML in WPF, UWP and Xamarin. XAML works very nice with the MVVM pattern (even if you do that lazily) with the data binding.
So now I'm working on my own data binding, which is both fun and saddening (because it's not in there already)1 -
During an internship, I had to use angular and angular material on a web app. I discovered the magic of 2way data-binding!1
-
Been depressed and bored for the past two days, wish I'm always like this. why?
I learned how to MVVM in WPF and Android.
If only Apple creates something similar to what Microsoft and Google did for data binding.
If it exists please let me know :)9 -
I actually do have something to rant about!
The people I've decided to work with... are complete and utter fools. They don't want to keep updated with new practices and merely talk about awesome stuff... Let me elaborate.
The first person is someone I spent really many hours just writing with, I've helped him build on his personal project, which has now become our project (which I've done most of the work on now). He keeps writing about things that aren't fucking relevant for the current task - furthermore, he completely refuses to use any type of collaboration software in order to keep an eye on tasks we want to, and already have completed. He likes Git but doesn't provide helpful git messages, sometimes even stuff like 'forgot this'.. never any freaking description of what's actually been done! Not even after agreeing it should be done, he just doesn't understand what a helpful message is apparently.
I might be a bit special regarding wanting to follow practices, but how the fuck do you make any amount of money by being so ignorant!? He was a WP 'developer' a while ago, and has since changed to JS and are using a framework which he doesn't understand - he can't even remember what the documentation states.
So why do I 'work' with him? He knows a lot of phrases he's read in books, blogs, and the likes. That makes him really inspirational and positive and he really wants to become successful(like me!). But over the last few months, I've realized how bad he is at programming - he doesn't know basic programming concepts and have a hard time applying any sort of knowledge to his programming. If it's not pre-built, he can't use it, not even if the documentation has specific examples. He barely grasps the concept of binding data to a variable. He wouldn't know how to access it again though, it's just for the sake of binding it to some existing functionality.
The other guy really likes his old style. He hired me to maintain some application. Which has turned out to be a hell of several small tasks he needs to be finished or reworked - with no clear definition of the task. Most of the time, he'll do some initial changes, show the changes to me, vaguely explain what they do (not what he's trying to achieve) and first THEN ask me to do these changes, most often in some files that don't exist (he uses the wrong filenames so I have to guess/ask where the changes need to be made).
To top it all off, old syntax is used and don't get me started on the spaces+tabs for indenting lines... Because I've already added a great ESLint+Prettier conf and everything should be nicely formatted according to pre-defined rules.
But he won't take the time to install some plugins in his editor and I'm left with sometimes buggy, badly formatted code (the code I have to make changes with!) - that's while he several times have agreed that I can do what I want and that he even questions his own ways when looking at my changes which he calls by-the-book.
So why the motherfucking fuck do I keep working with him?
Well, he keeps paying so that's really nice - I haven't been able to properly execute the bigger tasks(which pays more) though, due to a lack of information or some badly written code I couldn't quite figure out how works (at a glance).
He also keeps talking about these new projects he wants to make.. he even has these freaking papers with descriptions and data-structures and we converse really good about these new awesome projects. He also likes cryptocurrencies(which is an interest of mine he has inflamed quite a bit) and lastly, he seems like a genuinely nice guy who I'd like to spend some time with even besides coding and work.
So now I stand here - stuck with people that make me feel like a demi-god or something because I use a git style-guide and ESLint+Prettier with the Airbnb style-guide.
What should I do? I'd really like some remote work and have a desperate need for money... So much so, that I might even have to pick up a fulltime job, in order to save my sorry ass - all because I like speaking with people who just like the thought of programming...
I'm actually quite lonely with my thoughts and they are the two only people I've had some sort of relationship with - who has an invested interest in programming/dev... I really like that, despite having to follow their thoughts as they surely can't follow mine.
Please be my friend or give me some paid work lol.
Also, I've been moving the last couple weeks - those weeks has been the most stressful of my life and have not contributed to my overall wellbeing and relations with people... It's good to be back at the computer again and be reading some devRant though!1 -
Today a member of an other team said that React would be better than Angular 2. Mainly because React allows HTML inside the components declaration and One-Way-Data-Binding.
Me then: Sure, but Angular 2 also has this features 😞18 -
I give up! Been trying to solve this shit for a week and still failed:
Using Android Data Binding, two-way binding and when I compile I receive this error:
Unknown class: java.lang.String
It was working without issues before upgrading Android Studio.
Anyone has a clue how to solve this shit?
By the way I'm using Kotlin, on Java it doesn't produce errors, and I'm not going to convert my project to Java ...8 -
Was working on a high priority security feature. We had an unreasonable timeline to get all of the work done. If we didn’t get the changes onto production before our deadline we faced the possibility of our entire suit being taken offline. Other parts of the company had already been shut down until the remediations could be made -so we knew the company execs weren’t bluffing.
I was the sole developer on the project. I designed it, implemented it, and organized the efforts to get it through the rest of the dev cycle. After about 3 month of work it was all up and bug free (after a few bugs had been found and squashed). I was exhausted, and ended up taking about a week and a half off to recharge.
The project consisted of restructuring our customized frontend control binding (asp.net -custom content controls), integrations with several services to replace portions of our data consumption and storage logic, and an enormous lift and shift that touched over 6k files.
When you touch this much code in such a short period of time it’s difficult to code review, to not introduce bugs, and _to not stop thinking about what potential problems your changes may be causing in the background_.3 -
I'm currently working as a new team member on an angular project. It just took me an hour to understand the data flow for one single use case. Data is passed through 4 directives and each time with two-way binding. In contrast to angular2 you cant see whether an attribute is an input/output element, you always have to check the directive code. Funny thing, the controller of the directive is in an extra function and sometimes not even directly behind the directives code. Template, directive and controller sum up to 12 code placements I have to check in order to understand everything. All the directives seem to be neccessary because my boss wants everything DRY.3

What do people think of Vue.js over something like Polymer for making Progressive Web Apps?
I've used Polymer a lot (Angular 1 before that) and I'm not a fan of it's data binding. It is using a web standard though, so should have more components available than any library that makes it's own component system (like Vue.js). -
I have a very little working experience with someone else's code, and even lesser experience working with a professional code base. All my previous apps had around 8-9 java files at max, with very rare moduling and folders.
And this start up where am currently the intern, has handed me theiir develop branch, it has almost a 100 java files, 50 external libs, massive use of architectural designs ,data binding and custom views and so much more ! Damn, am overwhelmed , but so excited to learn the practices i was procrastinating for so long 💗💗💗
The only problem is lack of a mentor, since the sir who made this beauty is a superman who is currently handling the server and ai side and isn't usually available.
But i guess i will do fine, hell it's a FBI's data key in my hands :D1 -
AngularJs:
Two main Controllers (main layout, sub page) and two directives with controllers. Controllers and directives have two-way data binding. All of them use $watch, $broadcast, $on.
BRAINFUCK OF MY LIFE. DO NOT COMBINE WATCH WITH TWO-WAY DATA BINDING. -
Quick question on Android development. Is it good practice to access UI elements from code, i.e R.id.example? Or is there something similar to WPF's data binding?10

Having a lot of bad experiences while working as intern in startups and about to join a MNC, i wanted to share my work life balance and technical demands that i expect from a company. These are going to be my list of checkpoints that i look forward , let me know which of them are way too unrealistic. also add some of yours if i missed anything :
Work life balance demands ( As a fresher, i am just looking forward for 1a, 2a and 8, but as my experience and expertise grows, i am looking forward for all 10. Would i be right to expect them? ):
1a 8 hr/day. 1b 9h/day
2a 5days/week. 2b 6 days/week
3 work from home (if am not working on something that requires my office presence)
4 get out of office whenever i feel like i am done for the day
5 near to home/ office cab service
6 office food/gym service
7 mac book for working
8 2-4 paid leaves/month
9 paid overtime/work on a holiday
10.. visa sponsorship if outside india
Tech Demands (most of them would be gone when i am ready to loose my "fresher " tag, but during my time in internship, training i always wished if things happened this way):
1. I want to work as a fresher first, and fresher means a guy who will be doing more non tech works at first than going straight for code. For eg, if someone hires me in the app dev team, my first week task should be documenting the whole app code / piece of it and making the test cases, so that i can understand the environment/ the knowledge needed to work on it
2. Again before coding the real meaningful stuff for the main product, i feel i should be made to prepare for the libraries ,frameworks,etc used in the product. For eg if i don't know how a particular library ( say data binding) used in the app, i should be asked to make a mini project in 1-2 days using all the important aspects of data binding used in the project, to learn about it. The number of mini tasks and time to complete them should be given adequately , as it is only going to benefit the company once am proficient in that tech
3. Be specific in your tasks for the fresher. You don't want a half knowledgeable fresher/intern think on its own diverging from your main vision and coding it wrong. And the fresher is definitely not wrong for doing so , if you were vague on the first place.
4. most important. even when am saying am proficient , don't just take my word for it. FUCKIN REVIEW MY CODE!! Personally, I am a person who does a lot of testing on his code. Once i gave it to you, i believe that it has no possible issues and it would work in all possible cases. But if it isn't working then you should sit with me and we 2 should be looking, disccussing and debugging code, and not just me looking at the code repeatedly.
4. Don't be too hard on fresher for not doing it right. Sometimes the fresher might haven't researched so much , or you didn't told him the exact instructions but that doesn't mean you have the right to humiliate him or pressurize him
5. Let multiple people work on a same project. Sometimes its just not possible but whenever it is, as a senior one must let multiple freshers work on the same project. This gives a sense of mutual understanding and responsibility to them, they learn how to collaborate. Plus it reduces the burden/stress on a single guy and you will be eventually getting a better product faster
Am i wrong to demand those things? Would any company ever provide a learning and working environment the way i fantasize?3 -
No matter how many times I have to rewrite functional code, no one will ever convince me that dynamically creating JavaScript with data binding templating languages is a good idea (JSP, php, etc)3
-
Why did it take the JS community so long to understand that they are ultimately coding UI apps; and did not follow existing, solved GUI patterns (game loop style, one way data binding etc.) until recently? Any thoughts?
-
The problem with our current project is that we're using Spring MVC but we only use hashmap for binding (is binding is a correct term for this?) of data with our mapper (We use Mybatis, and also when we get this source code they already implements this kind of stuff, mvc with no models hahaha) for the sake the code to be consistent.
Maybe after I read the documentation of Mybatis and learn how to implements joins, I'll ask a permission to change the hashmap with actual models. -
Ugh Android OS is so vast and intimidating, i feel so unsure about it even after 3 years of learning it.
Like now i am about to graduate, so i need to look for a job. Those companies require knowledge of libraries like data binding, dagger, rx fabric, etc the stuff that i never personally used in any of my personal projects because i was able to handle all my stuff by general programming knowledge.
At the same time the os itself is so large and full of apis that i want to learn and spend my time upon. Like Android stores data, renddrs media , its databases, its lifecycles, gradle building , manifest etc
Can any devs share how they are proceeding with this os? I always feel like i am floating on the surface and not diving deep enough :/2 -
It is sometimes shocking to see 10+ developers working on a fairly big project (online quiz). Missing data binding operations here and there, as a result, bunch of sql injections, which successfully led to the entire db full of questions and answers sitting on my desktop.
Vulnerabilities have been reported, took them 2 weeks to understand what happened and fix them.
Pretty sad :/1 -
Trying to figure out why switching underlying object in data binding does not update.
checking type validation, nothing
checking types in bound events, nothing,
maybe some exceptions it thrown? nothing...
check the "class"... IT'S A FUCKING STRUCT -
Pro tip for XAML binding:
Set your data context before you initialize the component!
Otherwise the component will render with the default values for the properties. -
Hi So I need some solid advice from you all wonderful people.
I think i am now ready to look into job side of this world, but have lots of doubts , read my story.
I have been learning android for last 2 years. Most of the time i have been trying to understand how stuff works in android , but i have also gained a few other skills ( python programming, kotlin/flutter basics data analysis basics, testing, some graphic designing, aweful web dev ,etc). But i really want to work with Android. I don't have any specific Salary figure in mind, but i guess my knowledge is better or atleast par with most of the good android developers.
So i want to know how is this fresher/placement thingy work?
1.) GETTING KNOWN? : How can i make some good android based company aware that I am available for hiring? Should i start emailing every android related company that i know of? Should i start listing my profile on recruitment sites like linkedin or internshala? This year it is being said that companies will come for placements. From the status of my college, they are going to give me way to less $ , nd i know am not going to like any of them, but i guess i have to sit for them too.
2.INTERVIEW OR DIRECT PLACEMENTS? A little pre-context: i am currently starting my 4th year in clg. Afaik , 4th year isnt that strict and their can be leniency in terms of attendance. But my college is a place full of political cun*s in the name of directors and HODs and I don't know if they are again going to enforce the old 75% mandatory criteria. Plus if the company is from a different state/country , then my attendance would definitely not suffice.
So mainly i am unsure if somehow a company hires me, i would be able to start immediately. I heard that there are interviews for job recruitment after which the candidate is binded with an agreement to do some months training followed by permanent working after college completion.
This type of agreement is very much suitable for me, since from what my friend tells me, trainings can be lenient and understanding regarding exam preparations nd stuff.
So what do company usually chooses? Binding a fresher on immediate working basis or do they consider graduate completion?
Also, i suck at competitive coding. Do i need to polish myself on that or some company is willing to give me chance on the basis of my other skills 🙈(okay, no kidding , that's a serious question. I need to either work on getting better in competitive or build more apps based on that)
3.) ANDROID OR EVERYTHING? From what i have heard, working as a professional fresher is more like being an allrounder than being a domain specialist. But as i already stated, i really dig android and that's no small framework. I may di other stuff too, but won't interest me nd my output might be less efficient than expected.
So freshers can really be asked to do any stuff? Or can i still be in the area i like being into?
4.) COMPANY OR START-UP? Yeah, this is a general debate starter. Ignoring the business side of the conversation ( job safety vs more salary, experience, etc) the thing that's most important for me is the presence of a team. I want someone to assign me a task, whose vision i could follow, from whom i could learn, and some other people who are supportive and doing the same amount / similar work that am doing . This is so much import8 for me that i can easily ignore other factors for a better team. I once took a call from a startup ceo who hired me, a 2 month old android beginner at that time, as the "lead android developer"
But if am being on a team where i am supposed to do any random stuff that is assigned, then obviously this whole point of "visionary, helpful leader, guiding team, "etc goes moot9 -
I have recently learned to use data binding with recyclerView in android. I need to make some network calls on the click of a button at the recyclerView, and based on response I need to update my UI. All my code for the view is in my ViewHolder. Bt all the code for my network calls are in repository which is accessed by my viewModel. how can I make the network calls from the viewHolder?2
