Search - "meta programming"
So this is an update of the afore mentioned IT related RPG I am making. I have settled on the title "Lords of Bullshit: a tale of corporate incompetence".
I need some ideas guys. I have Java, C, Python, PHP, bash and git as skill types, but I need spells for each.
For example in C I have malloc and dealloc as spells (revive and death spells).
I am having trouble with Java spells. I am trying to come up with things that focus on OOP or reflection and meta programming, but I am having trouble.
Any ideas? Also, anyone want to help with some sprites? All of the sprites the character generator can make are medieval looking.19
Biggest annoyance in Ruby: nil is an object, nil's class is NilClass, NilClass's class is Class, Class's superclass's superclass is Object, and Object's superclass's superclass is basically BasicObject1
CAN SOMEONE PLEASE EXPLAIN TO ME WHAT THE FUCK LAMBDA CALCULUS IS??!?!?!
I swear to fuck, nothing makes you feel more like an idiot than trying to understand functional programming after living all your life in the oop world.
Fucking meta-functions and alligator games.
Fuck this, I'm going back to my happy little Java world11
Why is it that virtually all new languages in the last 25 years or so have a C-like syntax?
- Java wanted to sort-of knock off C++.
- C# wanted to be Java but on Microsoft's proprietary stack instead of SUN's (now Oracle's).
- Several other languages such as Vala, Scala, Swift, etc. do only careful evolution, seemingly so as to not alienate the devs used to previous C-like languages.
Now we're slowly arriving at the meat of this rant: back when I started university, the first semester programming lecture used Scheme, and provided a fine introduction to (functional) programming. Scheme, like other variants of Lisp, is a fine language, very flexible, code is data, data is code, but you get somewhat lost in a sea of parentheses, probably worse than the C-like languages' salad of curly braces. But it was a refreshing change from the likes of C, C++, and Java in terms of approach.
But the real enlightenment came when I read through Okasaki's paper on purely functional data structures. The author uses Standard ML in the paper, and after the initial shock (because it's different than most everything else I had seen), and getting used to the notation, I loved the crisp clarity it brings with almost no ceremony at all!
After looking around a bit, I found that nobody seems to use SML anymore, but there are viable alternatives, depending on your taste:
- Pragmatic programmers can use OCaml, which has immutability by default, and tries to guide the programmer to a functional programming mindset, but can accommodate imperative constructs easily when necessary.
- F# was born as OCaml on .NET but has now evolved into its own great thing with many upsides and very few downsides; I recommend every C# developer should give it a try.
- Somewhat more extreme is Haskell, with its ideology of pure functions and lazy evaluation that makes introducing side effects, I/O, and other imperative constructs rather a pain in the arse, and not quite my piece of cake, but learning it can still help you be a better programmer in whatever language you use on a day-to-day basis.
Obviously these curly-braces languages will still be needed for a long time coming, legacy systems and all—just look at COBOL—, but my point stands.7
When meta-programming finally clicks and your code can make its own code, which in turn makes its own code.1
The datepicker saga
So I begin work on a page where user add their details, project is late, taking ages on this page
Nearly done, just need a component to allow users to put in some date of births. Look for react components.
Avoiding that one because fuck Bootstrap.
Ah-ha, that looks good, let's give it a go.
CSS doesn't exist, oh need copy it over from npm dist. Great it applied but...
... WTF it's tiny. Thought it was a problem with my zoom. Nope found the issue in github.com and it's something to do with using REM rather than EM or something, okay someone provided a solution, rather I saw a couple of solutions, after some hacking around I got it working and pasted it in the right location and yes, it's a reasonable size now.
Only it's a bit crap because it only allows scrolling 1 month at a time. No good. Hunting through the docs reveals several options to add year and month drop downs and allow them to be scrolled. Still a bit shit as it only shows certain years, figure I'd set the start date position somewhere at the average.
Wait. The up button on the scroll doesn't even show, it's just a blank 5px button. Mouse scroll doesn't work
... Bailing on that.
Okay sod it I'll just make my own three drop down select boxes, day, month and year. Easy.
At this point I take full responsibility and cannot blame any third party. And kids, take this as a lesson to plan out your code fully and make no assumptions on the simplicity of the problem.
For some reason (of which I regretted much) I decided to abstract things so much I made an array of three objects for each drop down. Containing the information to pretty much abstract away the field it was dealing with. This sort of meta programming really screwed with my head, I have lines like the following:
But I was in too deep and had to weave my way through this kind of abstract process like an intrepid explorer chopping through a rain forest with a butter knife.
So I am using React and Redux, decided it was overkill to use Redux to control each field. Only trouble is of course when the user clicks one of the fields, it doesn't make sense in redux to have one of the three fields selected. And I wanted to show the field title as the first option. So I went against good practice and used state to keep track of the fields before they are handed off to the parent/redux. What a nightmare that was.
Possibly the most challenging part was matching my indices with moment.js to get the UI working right, it was such a meta mess when it just shouldn't have taken so stupidly long.
But, I begin to see the light at the end of this tunnel, it's slowly coming together. And when it all clicks into place I sit back and actually quite enjoy my abysmal attempt at clean and easy to read code.
Ran the generated timestamp through a converter and I get the day before, oh yeah that's great
Seems like it's dependant on the timezone??!
Nope. Deploying. Bye. I no longer care if daylight savings makes you a day younger.1
Interview on Monday. Buzzing! The company is pretty cool, they have a startup buzz but part of a wider umbrella of businesses so don't suffer from the financial uncertainty that destroyed my last company (that and my old boss was pretty clueless about everything except sales). They also give time for personal projects, allow remote working, bonuses if the company does well and provide its employees transparency to its finances.
In short, I'm not going to be a cog in a big corporate wheel. If I get this.
Well they liked the code I produced for their programming test, so good start.
Meta: categorised this as rant because it's tech related, but obviously it's not a rant, what's the protocol? Random?2
I've been working on a Programming playlist for a while and seems people want more of those, so I'll share mine as well
The following is a mix of dubstep, house, vocal EDM and a whole bunch of Rocket League music
A little critique won't be hated on (probably)
