You're not really a dev until you start laughing your ass off at every Hollywood attempt at writing a scene where a "computer whiz" does some amazing "hacking"1

For all of youse that ever wanted to try out Common Lisp and do not know where to start (but are interested in getting some knowledge of Common Lisp) I recommend two things:
As an introductory tutorial:
https://lisperati.com/casting.html/
And as your dev environment:
https://portacle.github.io/
Notice that the dev environment in question is Emacs, regardless of how you might feel about it as a text editor, i can recommend just going through the portacle help that gives you some basic starting points regarding editing. Learn about splitting buffers, evaluating the code you are typing in order for it to appear in the Common Lisp REPL (this one comes with an environment known as SLIME which is very popular in the Lisp world) as well as saving and editing your files.
Portacle is self contained inside of one single directory, so if you by any chance already have an Emacs environment then do not worry, Portacle will not touch any of that. I will admit that as far as I am concerned, Emacs will probably be the biggest hurdle for most people not used to it.
Can I use VS Code? Yes, yes you can, but I am not familiar with setting up a VSCode dev environment for Emacs, or any other environment hat comes close to the live environment that emacs provides for this?
Why the fuck should I try Common Lisp or any Lisp for that matter? You do not have to, I happen to like it a lot and have built applications at work with a different dialect of Lisp known as Clojure which runs in the JVM, do I recommend it? Yeah I do, I love functional programming, Clojure is pretty pure on that (not haskell level imo though, but I am not using Haskell for anything other than academic purposes) and with clojure you get the entire repertoire of Java libraries at your disposal. Moving to Clojure was cake coming from Common Lisp.
Why Common Lisp then if you used Clojure in prod? Mostly historical reasons, I want to just let people know that ANSI Common Lisp has a lot of good things going for it, I selected Clojure since I already knew what I needed from the JVM, and parallelism and concurrency are baked into Clojure, which was a priority. While I could have done the same thing in Common Lisp, I wanted to turn in a deliverable as quickly as possible rather than building the entire thing by myself which would have taken longer (had one week)
Am I getting something out of learning Common Lisp? Depends on you, I am not bringing about the whole "it opens your mind" deal with Lisp dialects as most other people do inside of the community, although I did experience new perspectives as to what programming and a programming language could do, and had fun doing it, maybe you will as well.
Does Lisp stands for Lots of Irritating Superfluous Parentheses or Los in stupid parentheses? Yes, also for Lost of Insidious Silly Parentheses and Lisp is Perfect, use paredit (comes with Portacle) also, Lisp stands for Lisp Is Perfect. None of that List Processing bs, any other definition will do.
Are there any other books? Yes, the famous online text Practical Common Lisp can be easily read online for free, I would recommend the Lisperati tutorial first to get a feel for it since PCL demands more tedious study. There is also Common Lisp a gentle introduction. If you want to go the Clojure route try Clojure for the brave and true.
What about Scheme and the Structure and Interpretation of Computer Programs? Too academic for my taste, and if in Common Lisp you have to do a lot of things on your own, Scheme is a whole other beast. Simple and beautiful really, but I go for practical in terms of Lisp, thus I prefer Common Lisp.
how did you start with Lisp?
I was stupid and thought I should start with it after a failed attempt at learning C++, then Java, and then Javascript when I started programming years ago. I was overwhelmed, but I continued. Then I moved to other things. But always kept Common Lisp close to heart. I am also heavy into A.I, Lisp has a history there and it is used in a lot of new and sort of unknown projects dealing with Knowledge Reasoning and representation. It is also Alien tech that contains many things that just seem super interesting to me such as treating code as data and data as code (back-quoting, macros etc)
I need some inspiration man......show me something? Sure, look for a game called Kandria in youtube, the creator, Shimera (Nicolas Hafner) is an absolute genius in the world of Lisp and a true inspiration. He coded the game in Common Lisp, he is also the person behind portacle. If that were not enough, he might very well also be Shirakumo, another prominent member of the Common Lisp Community.
Ok, you got me, what is the first thing in common lisp that I should try after I install the portacle environment? go to the repl and evaluate this:
(+ 0.1 0.2)
Watch in awe at what you get.
In the truest and original sense of the phrase (MIT based) "happy hacking!"10 -
The datepicker saga
Part one
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
Fucking...
... Bailing on that.
Part 2
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:
[...].map(optionGroup =>
optionGroup.options[
parseInt(
newState[optionGroup.momentId]
, 10)
]
)...
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.
Part 3
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 -
Someone is trying to get into my shit. Mail Accounts and my phone is receiving lots of. Spam calls and phishing messages...
Fucking bastards..
We all get phishing shit but if it’s targeted it makes me feel awkward..
Little fucking bastards.. I think I even know who it is.. that useless piece of junk that got fired because of my honest feedback. Not many others know my current nr, emails etc..7 -
I don't think there was a defining moment of clarity that I said "I want to be a dev". I became interested in computers when I started learning BASIC from a set of programming books that came with our family's encyclopedia set. I moved on to "hacking" some .ini files in a DOS game called Tank Wars to make the text in the game into vulgar insults. My friends and I would tear our parents computers apart and re-assemble them much to their chagrin. After a failed attempt at a Bachelor's Degree in Graphic Arts I decided to go back to school for CS. My CS degree was Windows centric but I really wanted to be a Linux SysAdmin so I started to learn on my own and switched to using Ubuntu as my primary system. Ever since then I have been a Linux HPC SysAdmin and haven't looked back!
