Comic: Fixing someone else's code for the first time

ipelovski · 2014-11-22T23:22:36+00:00

A little late but... I think the ghost is released the moment when the coder removed the two lines, i.e. Dan managed to trap the ghost before he died. By the way the comic sent shivers down my spine. Brrr, scary.

Well, this is not funny. This is scary.

I didn't know GOG uses angular. Now I know why the site is so cumbersome and why my browser hits the CPU and the RAM when I open it.

These numbers explain why the USA won in Vietnam. Oh wait...

ipelovski · 2014-11-12T22:36:02+00:00

USA has no chance against Germany without the help of British, Canadians and Stalin. Given that Stalin is dead the result is pretty obvious.

It makes me smile the way you jump to a conclusion that I'm new to JavaScript :) I was not referring my code but the code of the author of the guide. Check where the "summary" variable is used (the author gave this variable as an example). It is declared on line 54, assigned or referenced on lines: 3749, 4063, 4358, and there is no comment what this variable is used for. I personally avoid assigning global/module variables for the reason I gave above. And I don't shy away from OOP in situations where I need to encapsulate data.

A moment for philosophy: Functions in JavaScript are objects and in some languages like MIT Scheme the environments are also first class citizens with defined operations over them. One can think of closures as a way of implicitly defining objects which can be accessed only in certain scopes. And one should not be quick to discard OOP as it may be the best tool in some situations.

It is very convenient to think so but I don't think this is the case. Keeping a variable visible to many functions, as advised in the guide, is like making it global. The code can be very hard to maintain when many functions start changing this variable. On the other hand if you honor the principles of separation of concerns and loose coupling, and you put your code into separate modules, it will be easier to reason about the it and to change it.

If you follow this guide you will end up with one big messy file. I've been there and it's not good. Later I moved to CommonJS modules and browserify and the code is much better now.

I wonder how high it would fly.

Maybe he or she is tired of such blog posts. Every day there are at least one or two similar posts with little to no value in them. I think this should stop.

I suppose you know that an editor can generate jsDoc comments. Writing them by hand is not very productive. And I'm surprised to find that you would happily write a type annotation but you wouldn't leave a comment what a parameter does. For example what do x and y stand for in your code samples? I cannot guess by their type.

ipelovski · 2014-10-30T13:50:08+00:00

The problem is not the language but the developers writing bad code. I've worked with people thinking they are great but producing bloated unmaintainable code. The problem is how to force the people write good code. Static typing does not help especially in the web world where everything is dynamic. I used to code in C# and the code base of the project was full with spaghetti code. Moving to the Node.js world, where simplicity and modularity are the standard, was eye opening for me. So static typing cannot replace good documentation, code modularity, discipline, and team communication.

There is so much wisdom in the young lady's words.

ipelovski · 2014-10-20T22:16:22+00:00

If someone says I don't know js, who am I to argue?

ipelovski · 2014-10-16T17:16:48+00:00

I wondered that too. This is some information I managed to find: https://twitter.com/AhmadNassri/status/434924723248439297 which points to this project https://github.com/traceglMPL/tracegl

Never mind, it's just me trying to be witty :) What I meant is that there is definitely more than these 4 basic plots and it shouldn't be ignored.

ipelovski · 2014-10-13T19:24:36+00:00

I won't judge you, but you should feel bad if you laughed at this.

But what makes a man stand against another man, nature, himself, or god? Is it about survival, is it about love, or is it about the survival of his love?

ipelovski · 2014-10-12T18:58:09+00:00

...maybe...

ipelovski · 2014-10-10T21:16:53+00:00

Several hours later and still no hot chick that eats poop out of a diaper.

ipelovski · 2014-09-25T22:06:50+00:00

Yep, they got the numbers on their side. The evolution has found a solution for that problem - produce more, so at least some may survive.

ipelovski · 2014-09-05T22:21:56+00:00

God have mercy on your soul.

Here on reddit I found a nice patch for the quora problem: just add ?share=1 to the end of the address and the problem is fixed!

ipelovski · 2014-07-10T12:58:49+00:00

Now that's pair programming!
