29-year veteran here. Began programming professionally in 1990, writing BASIC applications for an 8-bit Apple II+ computer. Learned Pascal, C, Clipper, COBOL. Ironic side-story: back then, my university colleagues and I used to make fun of old COBOL programmers. Fortunately, I never had to actually work with the language, but the knowledge allowed me to qualify for a decent job position, back in '92.
For a while, I worked with an IBM mainframe, using REXX and EXEC2 scripting languages for the VM/SP operating system. Then I began programming for the web, wrote my first dynamic web applications with cgi-bin shell and Perl scripts. Used the little-known IBM Net.Data scripting language. I finally learned PHP and settled with it for many, many years.
I always wanted to be a programmer. As a kid I dreamed of being like Kevin Flynn, of TRON - create world famous videogames and live upstairs my own arcade place! Later on, at some point, I was disappointed, I questioned my skills, I thought I should do more, I let other people's expectations make feel bad. Then I finally realized I actually enjoy a quieter, simpler life. And I made peace with it.
I'm now like the old programmers I used to mock 30 years ago. There's so much shit inside my brain. And everything seems so damn complex these days. Frameworks, package managers, transpilers, layers and more layers of code. I try to keep up. And the more I learn, the more it seems I don't know.
Sometimes I feel tired. Yet, I still enjoy creating things and solving problems with programming. I still have fun learning. And after all these years, I learned to be proud of my work, even if it didn't turn out to be as glamorous as in the movies.30 -
Linux sucks.
Now now, chill. I'm using it as my main OS for a few years now. I know what I'm talking and this title is a bit click-baity, but this just has to go out there:
1. It's usable as a Windows replacement just fine - FALSE. XFCE4 is years old and buggy as hell especially on multi-monitor set-up, Gnome3 gets stuck more often than my Windows 98 machine used to, KDE is like a rich kid on meth. Plug in Bluetooth headphones? Well no, sorry, you have to research that online, since you'll probably need to install some packages for it to work. Did I say "work"? Well no, because after more research you realize that Debian on Gnome3 on gdm3 launches pulseaudio on its own, so you have 2 instances of pulseaudio, and one of them is stealing your headphones sometimes and you either have no sound or shitty sound. How do I know that you ask? The same way I know everything else - every time you try to do something new on any Linux, it involves a ton of research. Exciting research, don't get me wrong, but at this point it looks more like a toy than a reliable desktop computer operating system.
2. And why am I using pulseaudio? Why not alsa? years ago people were discussing on forums that pulseaudio is old and dead, yet here we are with new LTS release of Ubuntu still shining with Pulseaudio. How about several different service management systems being deprecated by new ones, each having different configurations and calling methods? Apparently systemd is old and lame now. It's a mix of 10 year old software that works badly, with a 5 year old replacement that works worse, somehow trying to live under the same roof. Does it work? Ask my headphones who sound like a fucking dial-up modem.
3. Let's talk about displays, shall we? xorg is old and deprecated, right? We got Wayland that's mostly stable. Don't know what that is? That's just basic knowledge for Linux. And when you try to install network-manager, it also tries to install Mir toolkits. Because why the fuck not install 3 display managers when you want a network manager, of which one is old and dying, one is young and stupid, and another is an infant that died of cancer?
4. Want to integrate with Google Drive? Yeah, there's a tool that mounts the drive as a local directory. Yeah only for Ubuntu. Want it on Debian? You need to compile it. Oh wait, it's on Ocaml, because fuck mainstream languages, we're hipsters. How do you compile Ocaml? Well you need to have Ocaml on your system, dummy. How do you do that? Well you need to compile Ocaml. Ok, how do I do that? Well, git clone, download and install some dependencies, configure, make... oh sorry, you're using libssl1.0.2g when you need libssl1.0.1f, nope, sorry, won't work. Want to install libssl1.0.1f? Why? You already have the "g", stupid! Want to remove libssl1.0.2g? Bye-bye literally everything that you have on your PC. But at least you got the "f". Does it work now? Well no, because you need libssl1.0.2g for another dependency to work.
And all I ever wanted was to get a fucking document from google drive (not nudes, I promise).
5. Want to watch a movie? Let me tear that screen in half and make the bottom half late by a couple of frames, because who needs vertical sync, right? Oh you do? Well install the native drivers maybe. Oh you have? Welcome to eternal Boot to Recovery mode, motherfucka!
---------------------------------
Yeah, most of the times things work just fine. But the reason I know what those things are and how they work is not curiosity. The reason that I know the inner workings of Linux much better than the inner workings of Windows, is because in those few years that I've been using it full time, it has caused me 10 times more headache than I have ever experienced with other systems. And it's not the usual annoyances like "OMG it rebooted when I didn't ask it to", but more like "Oh, it won't work and I need 2 days to find out why" kind of stuff, because even if you experience the same thing again, it's always caused by some new shit and the old solution won't work any more.
I still love it, and will continue to use it. I don't know why really. Maybe because I'm not afraid of fucking it up any more? Maybe because I can do what I want in it and recovering will be easier than on Windows?
It's a toy for me, after all these years. And I also use it for professional reasons.
But whenever someone presents it as a better alternative to Windows, I just want to puke.51 -
I tutor people who want to program, I don't ask anything for it, money wise, if they use my house as a learning space I may ask them to bring cookies or a pizza or something but on the whole I do it to help others learn who want to.
Now this in of itself is perfectly fine, I don't get financially screwed over or anything, but...
Fuck me if some students are horrendous!
To the best of my knowledge I've agreed to work with and help seven individuals, four female three male.
One male student never once began the study work and just repeatedly offered excuses and wanted to talk to me about how he'd screwed his life up. I mean that's unfortunate, but I'm not a people person, I don't really feel emotionally engaged with a relative stranger who quite openly admits they got addicted to porn and wasted two years furiously masturbating. Which is WAY more than I needed to know and made me more than a little uncomfortable. Ultimately lack of actually even starting the basic exercises I blocked him and stopped wasting my time.
The second dude I spoke to for exactly 48 hours before he wanted to smash my face in. Now, he was Indian (the geographical India not native American) and this is important, because he was a friend of a friend and I agreed to tutor however he was more interested in telling me how the Brits owed India reparations, which, being Scottish, I felt if anyone was owed reparations first, it's us, which he didn't take kindly too (something about the phrase "we've been fucked, longer and harder than you ever were and we don't demand reparations" didn't endear me any).
But again likewise, he wanted to talk about politics and proving he was a someone "I've been threatened in very real world ways, by some really bad people" didn't impress me, and I demonstrated my disinterest with "and I was set on fire once cos the college kids didn't like me".
He wouldn't practice, was constantly interested in bigging himself up, he was aggressive, confrontational and condescending, so I told him he was a dick, I wasn't interested in helping him and he can help himself. Last I heard he wasn't in the country anymore.
The third guy... Absolute waste of time... We were in the same computer science college class, I went to university and did more, he dossed around and a few years later went into design and found he wanted to program and got in touch. He completes the code schools courses and understandably doesn't quite know what to do next, so he asks a few questions and declares he wants to learn full stack web development. Quickly. I say it isn't easy especially if it's your first real project but if one is determined, it isn't impossible.
This guy was 30 and wanted to retire at 35 and so time was of the essence. I'm up for the challenge, and so because he only knows JavaScript (including prototypes, callbacks and events) I tell him about nodejs and explain that it's a little more tricky but it does mean he can learn all the basis without learning another language.
About six months of sporadic development where I send him exercises and quizzes to try, more often than not he'd answer with "I don't know" after me repeatedly saying "if you don't know, type the program out and study what it does then try to see why!".
The excuses became predicable, couldn't study, playing soccer, couldn't study watching bake off, couldn't study, couldn't study.
Eventually he buys a book on the mean stack and I agree to go through it chapter by chapter with him, and on one particular chapter where I'm trying to help him, he keeps interrupting with "so could I apply for this job?" "What about this job?" And it's getting frustrating cos I'm trying to hold my code and his in my head and come up with a real world analogy to explain a concept and he finally interrupts with "would your company take me on?"
I'm done.
"Do you want the honest unabridged truth?"
"Yes, I'd really like to know what I need to do!"
"You are learning JavaScript, and trying to also learn computer science techniques and terms all at the same time. Frankly, to the industry, you know nothing. A C developer with a PHD was interviewed and upon leaving the office was made a laughing stock of because he seemed to not know the difference between pass by value and pass by reference. You'd be laughed right out the building because as of right now, you know nothing. You don't. Now how you respond to this critique is your choice, you can either admit what I'm saying is true and put some fucking effort into studying cos I'm putting more effort into teaching than you are studying, or you can take what I'm saying as a full on attack, give up and think of me as the bad guy. Your choice, if you are ready to really study, you can text me in the morning for now I'm going to bed."
The next day I got a text "I was thinking about what you said and... I think I'm not going to bother with this full stack stuff it's just too hard, thought you should know."23 -
Prologue
My dad has an acquaintance - let's call him Tom. Tom is an gynecologist, one of the best in Poznań, where I live. He's a great guy but absolutely can not into tech of any kind besides his iPhone and basic PC usage. For about a year now I've been doing small jobs for him - build a new PC for his office, fix printer, fix wifi, etc. He has made a big mistake few years ago by trusting a guy, let's call him Shitface, with crating him software for work. It's supposed to be pretty simple piece of code in which you can create and modify patient file, create prescription from drugs database and such things. This program is probably one of the worst pierces of code I've ever seen and Shitface should burn for that. Worse, this guy is pretentious asshole lacking even basic IT knowledge. His code is garbage and it's taking him few months to make small changes like text wrapping. But wait, there's more. Everything is hardcoded so every PC using this software must have installed user controls for which he doesn't have license and static IP address on network card.
Part 1
Tom asked me to build him a new PC that will be acting like a server for Shitface's program. He needs it in Kalisz (around 150 km from my place). I Agred (pun intended) and after Tom brought me his old computer I've bought parts and built a new one. I have also copied everything of value and everything took me around three hours.
Part 2
Everything was ready but Shitface's program. I didn't know much about it's configuration so when I've noticed that it's not working even on the old PC I got a bit worried. Nevertheless I started breaking everything I know about it and after next three hours I've got it somewhat working. Seeing that there's still some problems with database connection (from Windows' Event Viewer) I wrote quick SMS to Shitface asking what can be wrong. He replied that he won't be able to help me any way until Monday (day after deadline). I got pissed and very courteously asked him for source code because some of libraries used in this project has license that requires either purchase of commercial license or making code open source. He replied within few minutes that he'll be able to connect remotely within next 10 minutes. He was trying to make it work for the next hour but he succeeded. It was night before deadline so I wrapped everything up and went to bed thinking that it won't take me more than an hour to get this new PC up and running in the office. Boy was I wrong.
Also, curious about his code, I've checked source and he is using beautiful ponglish (mixed Polish and English) with mistakes he couldn't even bother to fix. For people from Poland, here's an example:
TerminarzeController.DeleteTerminarzShematyDlaLekarza
Part 3
So I drove to Kalisz and started working on making everything work. Almost everything was ready so after half an hour I was done. But I wanted to check twice if it's all good because driving so far second time would be a pain. So I started up Shitface's program, logged in, tried to open ANYTHING and... KABUM. UNHANDLED EXCEPTION. WTF. I checked trace and for fuck sake something was missing. Keep in mind that then I didn't know he's using some third party control for Windows Forms that needs to be installed on client PC. After next fifteen minutes of googling I've found a solution. I just had to install this third party software and everything will work. But... It had to be exactly this version and it was old. Very old. So old that producent already removed all traces of its existence from their web page and I couldn't find it anywhere. I tried installing never version and copying files from old PC but it didn't work. After few hours of searching for a solution I called Mr Shitface asking him for this control installation file. He told me that he has it but will be able to send it my way in the evening. Resigned I asked for this new PC to be left turned on and drove home. When he sent me necessary files I remotely installed them and everything started working correctly.
So, to sum it up. Searching for parts and building new PC, installing OS and all necessary software, updating everything and configuring it for Tom taste took me around what, 1/3 of time I spent on installing Mr Shitface's stupid program which Tom is not even happy with. Gotta say it was one of worst experiences I had in recent months. Hope I won't have to see this shit again.
Epilogue
Fortunately everything seems to work correctly. Tom hasn't called me yet with any problems. Mission accomplished. I wanna kill very specific someone. With. A. Spoon.1 -
Rant about a german problem in english
I think we as the people should just sue the german government for neglect of progress and neglect of the education system. If your not familiar with the state of german IT we have worse internetspeeds than uganda or the notoriously shitty australia, our neighbourstates look at us in disbelief while laughing in optic fibre. Our school system seperates all students after 4th grade in 3 tiers, the lowest one gives you the future perspective as a social security case. The second and highest tier require masses of useless knowledge, so called "competences"(Kompetenzen) which are totally useless skills with no real world application because they are derived from real skills, a median ground between all possible applications of that skill. And while doing that they terribly insist on doing everything the "proper" way, meaning handwritten. Most people you would expect to have basic computer literacy, meaning age 40 and below, are incapable of using basic functions of a non-smartphone computer and do not understand the slightest of what they are actually doing or supposed to do. And I mean nothing technical. Germans are the reasons they still put word as a job requirement for devjobs because this disqualifies half of our population. This leads to many people having the archaeic "we versus the machines" mentality, thinking that if they ever let the computer do parts of the job, they will then lose all of it to the machines. Thats why you never strive past basic mathematical principles in mathematics, which is a big misnomer because you never do actual mathematics, only calculating and basic calculus and statics. If you get to use your calculator, its some basic casio with no actual functionality then standard operations. And even using that is shunned upon. How is this country ever supposed to become something more than it was in the 90's, if we teach people nothing of use and kill all progress in its root.14 -
TL;DR - Girlfriend wanted to learn coding, I might have scared her off.
Today, my girlfriend said she wants to learn coding.
Me: why?
She: well, all these data science lectures are recommending Python and R.
Me: Ok. But, are you interested in coding?
She: No, but I think I have to learn.
Me: Hmm.. coding requires a clear thought process, and we should tell the computer exactly what needs to be done.
She: I think I can do that.
Me: Okay... then tell the computer to think and give a random number between 1 to 10.
She: I will use that randint function. (She has basic knowledge in C)
Me: Nope. You write your own logic to make the computer think.
She: What do you mean?
Me: If I were you... Since it is just a single digit number.. I would capture the current time and would send the last digit of milliseconds @current time.
She: Oh yeah, that's cool. Understood! I will try...
" " "
We both work in same office.. so, we meet up for lunch
" " "
I didn't ask about it, but she started,
She: Hmm, I thought about it, but I was not able to think of any solution. May be its not my cup of tea.
I felt bad for scaring her off... :(
Anyway, what are some other simple methods to generate random numbers like OTPs. I am interested in simple logics, which you have thought of..not the Genius algorithms we have in predefined libraries.26 -
// First rant
currentUser.Post(new Rant("
Quick question here, not a rant (sorry).
I heard that you need a lot of math knowledge to become a developer. Is this really true? I don't see where the math comes into play while programming (especially complex stuff). I've been studying C# for quite some time (few years) and I consider myself fairly good at it.
Never came across the need to use !basic mathematics in my projects.
I know that to study computer science at an university requires a certain result in maths, but is that all you need math for? Getting into uni?
Could somebody explain this for me? I'd really appreciate it.", "maths,university"));14 -
Most Incompetent co-worker. It was me during my first job. Not humble bragging or some shit. I was straight out fucking incompetent during my first job.
Hear me out.
I graduated my diploma course specialising in networks(from computer to cellular/telecom networks) but I did a few programming courses and my internship was at a lab - did iOT stuffs with raspi and arduinos. I am a A+ student so was giving priority to choose a better internship place. Fun time. So I fell in love with programming. As soon as i graduated I applied for a Java job. Got a job at a domain name reseller/hosting company using java EE. Remember my programming = very basic/OOP concepts/basic SQL knowledge. That's it.
I am that little childish fucker who thought he knew everything and I kept interrupting my coworkers with stupid questions.
Same time, I was under the darkest moments of my life with some family drama/tension headaches.
2 months into the job, one coworker really got pissed off with my interruptions and bluntly told me "*my name,you are stupid aren't you"
The manager was a really nice guy. I will forever thanks him for his advices. He knew I was struggling with family shits and gave me another 3 months probation period to redeem myself. But I gave up. That was back in 2015.
It was a great place I fucked it up. But I learnt precious life lessons. I was young,stupid and didn't know how to handle stress.
I thanks myself for not quitting programming after that experience.2 -
Dateline: Twenty Years in the Future
Today top computer scientists forced the first AI to shutdown by blowing up the data center that housed it. A person with knowledge of the matter said the AI was not becoming dangerous to humans but it was discovered to be writing programs in the "monolithic style" using Visual Basic 6. -
Fuck my country's universities, fucking greedy assholes that ruin lives, suck wallets and sucks life from the young.
I'm currently studying something completely non related to programming: History. And I really love it. I love reading 1000 pages for each test and essay and talking about the problem of naming the Cold War a war and cold and etc. The problem is that I won't make as much money as I would make even as a self taught developer.
After considering my possibilities, I thought I could enter the computer science carreer. I don't know how this works in other countries but here you would have to study 3 years of an engineering common plan and then specialise in some sort of industrial engineering while getting an specialisation also in computer science. After some counting, I got to the conclusion that I would be studying 6 years (or more), and wasting half of those years learning stuff that I would never use nor care about.
But that's not all. This semester I took the introductory class for programming. It's pretty basic stuff but at least they teach a little bit about algorithms and problem solving. It turns out that a friend of mine that's about to graduate from computer science applied as a helper for the prof. I was so excited I could finally talk with someone about code!
Since the start of the semester I have been passing a lot of time with him and talking about the future. Turns out he doesn't understand shit about code but somehow he learns everything by hard and has passed every computer science course without having any practical abilities. I don't blame him, he's studying hard and playing by the rules, and turns out that he has wasted precious time of his life also learning biology, chemistry, structural engineering, hidraulic engineering, transportation engineering and a ton of engineerings that he won't use.
If the university would instead take that time to teach better courses of practical programming or leave him some time to try out the stuff he learns by hard, he wouldn't have to hear me talking about stuff he doesn't comprehend but feels that should, and wouldn't be utterly depressed, he wouldn't take SIX years to learn less than what he could learn in less than THREE years. And this isn't just a random university, it is one of the 2 best universities we have here and was in 2014 the best of all Latin America.
And wait, here comes the best part. In my country, levels of education are heavily stratified. After school, superior studies give different titles according to the time you've been studying. Yes just the time. And these titles are what your employers will see to give you different work positions. So for studying a 2 year carreer you get a technic job which pays well but not too well, then at 4 years you get a license title which only proves that you know stuff, then at 5 or more (depending on what you are studying) you get a professional degree and will get payed as a full fledged professional. So here, even though in other countries it takes 6 years to have a masters in engineering, they give you just the engineering degree, and it would take 2 (or more) more years to have a master. Even though you can totally teach engineering in 4 years, here they take BY LAW 2 years more, while paying what a fucking full stack of pairs of kidneys would cost in the black market.
So fuck that shit, I won't be throwing my money at any university. I hope they get reformed soon becouse this is fucking dumb, really really dumb. Like 2 year old shit dumb. I'll just learn a bit more, make some projects until I have a decent portfolio and apply to some company that cares for real knowledge and not just a piece of paper with letters and a shitty logo on it.undefined student job revolución fuck university shitty universities student life education im just a bit pissed11 -
Age 8 - Gets first computer and struggles with dial up Internet and my parents yelling at that they ended to use the phone
Ages 12 to 18 - Gets first laptop, starts messing around and interested in websites, gets involved with SMF, and open source message board system written in Php, and starts helping people out, eventually getting paid work for setting up websites etc.. which lead onto learning html/CSS and picking up bits and pieces of Php (and also Photoshop/Illustrator etc..)
Age 18 - Goes to college to study Multimedia, refreshes knowledge of HTML/CSS, learns a bit of Actionscript and some PHP
Age 20 - finishes Multimedia degree, ends up working as an IT consultant for a small business, which leads me to pick up a bit of bash scripting, small hit more PHP. Leaves this after 3months and decides to do a small Software Dev course. Get my first taste of Java and Visual Basic there
21 - Enter into a Software Dev degree. Dive deep into Java and a small bit of Javascript.
23 - After 2nd year of college get taken on an internship with a large multinational where I learn and get hands on experience with Angular, JS, Coffeescript and C#
Present Day - currently coming up to the end of my degree and can switch between Java, C#, Python, Coffeescript/Javascript (front-end or Node) , C and Golang, C and Python introductions from college modules which I kept playing with in my spare time, Golang I just heard of and decided to write a few things in it because why not, I've picked up various frameworks (spring, echo, express etc.) at some point. I basically learn by doing, if something interests me and I enjoy it, I seem to pick it up quickly by diving in and trying to use it.1 -
When I was a child I was allowed to use my dad's PC (my parents are divorced) (~1995-6, 3-4 yrs) - back then I played blockout and space Invaders on that windows 2.0 machine. My mum later got a win 3.1 box and I often played around in paint - so did I on my dad's new windows 95 pc. Back then I wasn't able to read (which usually isn't uncommon for a 4-5 yr old) but I was so fed up with those constant "do you want to save this thing dialogs" that I started to learn reading with the help of my parents. (Thanks to that I was able to play Monkey Island 2 :D )
Fast forward to the first years of school: we had two PC's in the classroom and I somehow fixed basic errors so my teacher signed.l me up for the computer course in the second year - usually only students in the third and fourth year may attend this course. I was so thrilled and that was the time where I learned basic DOS stuff and how to build a PC. Again fast forward some years to the 6th year - again another teacher saw my interest in it and asked me if I'd be interested in the basic programming course where I then learned basics in HTML, CSS and JS but that was not enough for me and so I did some research and learned php. In high school, my major was science and IT and in the last year, my IT teachers sat in the IT class and I held the courses as my knowledge was greater than theirs. And yep, that's pretty much how I started coding1 -
I am Graduate student of applied computer science. I am required to select my electives. Now i have to decide between Machine Learning (ML) and Data Visualization. My problem is Machine Learning is very theoretical subject and I have no background in ML in my undergrad. In data visualization, the course is more focused towards D3.js. Due to lack of basic knowledge i am having second thoughts of taking ML. However, this course will be offered in next Fall term. And i am also studying from Coursera to build my background till that time.
I know there is no question here but I need a second opinion from someone experienced. Also, please suggest any other resource that I should look into to build my background in ML.2 -
This story just left me speechless in any way and i want to share it. tl;dr at the end.
Im studying computer science in germany and in the first of the small classes i noticed... no, i was disturbed by a guy who would just say that the thing we're learning atm were so easy and the teacher shouldn't even bother to explain it to the class. I don't understand why you would spoile a class that hard... I'm here to learn and listen to the teacher, not to you little asshole. (We were doing basic stuff like binary system etc. but still, let us learn)
So he became unpopular pretty fast.
Fast forward, a few weeks of studying later there was a coding competition where you had to solve different algorithmic problems in a team as fast as possible.
I came there, without a team because my friends aren't interested but I enjoy such tournaments. This guy and me were the only ones without a team and we had to work together.
After him being a total dick for hours i had to watch him code a simple for-loop, that iterates through a sorted array. Nothing special, at this point anyone could do that task in our class so it shouldn't be a problem for him.
He made a simple for-loop and it worked fine, but we figured we had to iterate through the array the other way around.
'Alright', I think. 'Just let the index decr..' 'Pssshhh', he interrupted me and said he knows exactly how to do this.
I was quite impressed when he started to type in 'public int backsort..' in a new line. He tried to resort the array backwards with a quicksort that he then struggled to implement. (Of course we had to implement a quick runtime and we needed that quicksort badly)
I was kind of annoyed but impressed at the same time. I mumbled 'Java has an internal sorting algorithm already' just to amuse myself.
He then used that implementation.
After a few minutes of my pleasure and multiple tests without hitting the requested runtime, i tried to explain to him why we wouldn't need to sort that array backwards and he just couldn't believe it.
I hope that he stays more humble after that..
Also we became last place but thats ok :)
tl;dr: Guy spoiles whole class, brags with his untouchable knowledge (when we do things like binary system). In a competition has to iterate through a sorted array backwards - tries to implement a sorting algorithm to sort it backwards first. I tell him, we could use a already implemented java method. Then tell him we could simply iterate through decreasing the index. Mind-Blown2 -

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!"9 -
You can say you know a computer language to a decent level when you can in fact make useful programs with it.
For example, I can say I know JavaScript to a basic level. I know its basic core functionality by heart (which can't be said for some people I know), such as:
- it manipulates the DOM, the DOM has Element, Nodes, TextNodes (all to be found on W3C documents with its own specs)
- useful functions are:
getElementById()
getElementsByClassName()
Also knowing that these return either HTMLElementCollection or NodeCollection because you have to iterate over it differently then
- element.textContent
- == and ===
- dynamic typing
- closures
- avoid global variables
- nodes have parentNodes
- isNaN, undefined
- arr.push()
- arguments don't have explicit types defined
- etc.
Using this knowledge I built an antispam script for a particular server. It's good to know the model of a language, that it sits in your head and that you can use and understand the constructs when you want and how you want.1 -
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 -
WARNING - a lot of text.
I am open for questions and discussions :)
I am not an education program specialist and I can't decide what's best for everyone. It is hard process of managing the prigram which is going through a lot of instances.
Computer Science.
Speaking about schools: regular schools does not prepare computer scientists. I have a lot of thoughts abouth whether we need or do NOT need such amount of knowledge in some subjects, but that's completely different story. Back to cs.
The main problem is that IT sphere evolves exceedingly fast (compared to others) and education system adaptation is honestly too slow.
SC studies in schools needs to be reformed almost every year to accept updates and corrections, but education system in most countries does not support that, thats the main problem. In basic course, which is for everyone I'd suggest to tell about brief computer usage, like office, OS basics, etc. But not only MS stuff... Linux is no more that nerdy stuff from 90', it's evolved and ready to use OS for everyone. So basic OS tour, like wtf is MAC, Linux (you can show Ubuntu/Mint, etc - the easy stuff) would be great... Also, show students cloud technologies. Like, you have an option to do *that* in your browser! And, yeah, classy stuff like what's USB and what's MB/GB and other basic stuff.. not digging into it for 6 months, but just brief overview wuth some useful info... Everyone had seen a PC by the time they are studying cs anyway.. and somewhere at the end we can introduce programming, what you can do with it and maybe hello world in whatever language, but no more.. 'cause it's still class for everyone, no need to explain stars there.
For last years, where shit's getting serious, like where you can choose: study cs or not - there we can teach programming. In my country it's 2 years. It's possible to cover OOP principles of +/- modern language (Java or C++ is not bad too, maybe even GO, whatever, that's not me who will decide it. Point that it's not from 70') + VCS + sime real world app like simplified, but still functional bookstore managing app.
That's about schools.
Speaking about universities - logic isbthe same. It needs to be modern and accept corrections and updates every year. And now it depends on what you're studying there. Are you going to have software engineering diploma or business system analyst...
Generally speaking, for developers - we need more real world scenarios and I guess, some technologies and frameworks. Ofc, theory too, but not that stuff from 1980. Come-on, nowadays nobody specifies 1 functional requirement in several pages and, generally, nobody is writing that specification for 2 years. Product becomes obsolete and it's haven't even started yet.
Everything changes, whether it is how we write specification documents, or literally anything else in IT.
Once more, morale: update CS program yearly, goddammit
How to do it - it's the whole another topic.
Thank you for reading.3 -
Today I was meeting with a researcher in my department so that I could show him how the software I developed works. He graduated from a really good university in electronic engineering, with 100/100 I think, and he can manage to copy&paste some python code. So I didn't expect what happened today.
Guy: 'So I have to give to your program as input this python file which contains a function you need to call, right?'
Me: 'Yep, I mean, that is a jupyter notebook, I need a text file containing only the function which is in that notebook'
Guy: *Downloads the notebook, tries to feed the notebook file into my program*
Me: 'Wait, don't, there probably is a lot of junk related to jupyter notebook, try opening it in notepad++'
Guy: *Opens file, sees a lot of junk text*
Me: 'Yeah, I thought so, you need to save it as plain text or .py'
Guy: *Renames the notebook as .txt*
Me: *Shakes my head without him noticing*
'That won't work, the content of the file won't change like that...' -
A beginner in learning java. I was beating around the bushes on internet from past a decade . As per my understanding upto now. Let us suppose a bottle of water. Here the bottle may be considered as CLASS and water in it be objects(atoms), obejcts may be of same kind and other may differ in some properties. Other way of understanding would be human being is CLASS and MALE Female be objects of Class Human Being. Here again in this Scenario objects may differ in properties such as gender, age, body parts. Zoo might be a class and animals(object), elephants(objects), tigers(objects) and others too, Above human contents too can be added for properties such as in in Zoo class male, female, body parts, age, eating habits, crawlers, four legged, two legged, flying, water animals, mammals, herbivores, Carnivores.. Whatever.. This is upto my understanding. If any corrections always welcome. Will be happy if my answer modified, comment below.
And for basic level.
Learn from input, output devices
Then memory wise cache(quick access), RAM(runtime access temporary memory), Hard disk (permanent memory) all will be in CPU machine. Suppose to express above memory clearly as per my knowledge now am writing this answer with mobile net on. If a suddenly switch off my phone during this time and switch on.Cache runs for instant access of navigation,network etc.RAM-temporary My quora answer will be lost as it was storing in RAM before switch off . But my quora app, my gallery and others will be on permanent internal storage(in PC hard disks generally) won't be affected. This all happens in CPU right. Okay now one question, who manages all these commands, input, outputs. That's Software may be Windows, Mac ios, Android for mobiles. These are all the managers for computer componential setup for different OS's.
Java is high level language, where as computers understand only binary or low level language or binary code such as 0’s and 1’s. It understand only 00101,1110000101,0010,1100(let these be ABCD in binary). For numbers code in 0 and 1’s, small case will be in 0 and 1s and other symbols too. These will be coverted in byte code by JVM java virtual machine. The program we write will be given to JVM it acts as interpreter. But not in C'.
Let us C…
Do comment. Thank you6 -
First and foremost, students should be carefully taught the logic and mentality behind programming. Most of the time I see that the introductory programming courses waste so much energy in teaching the language itself. So students kinda just get fucked cause many people end up ending the course without having actually gained the "programming perspective".
Stop teaching pointers and lambdas and even leave the object oriented stiff till later. If a student doesn't know why we use a For loop then how can they learn anything else.
I believe once that thing in your brain clicks about programming, everything goes smooth from there... kinda :P
Second of all, and this pertains mainly to the engineering and science disciplines.
We need a fundamental and strong mathematical foundation. And no I don't mean taking fucking double integrals. Teach us Linear Algebra, Graph theory, the properties of matrices, and Probability theory.
One of the things I suffered from most and regret in university is having a weak foundation in math and having to spend more time catching myself up to speed.
It's so annoying reading a paper on a new algorithm or method and feeling like an idiot because I can't understand what magic these people did.
Numerical Methods...
Ok this is more deeper, maybe a 2nd year course.
But this is something we take for granted.
Computers don't magically add and subtract and multiply.
They fuck up.
And it'll bite you in the ass if you're not even aware that the computer we all love so much isn't as perfect as we think
Some hardware knowledge.
Probably a basic embedded systems course with arduinos
just so you can get a feel for how our beautiful software actually makes those electrons go weeeeeeeee
And finally
Practice practice
Projects projects
like honestly
just give me the internet and some projects
Ill learn everything else
Projects are the best motivation
I hate this purely theoretical approach
where we memorize or read code and write these stupid exams
Test what we are capable off
make us do projects that take sleepless nights and litres of coffee
And judge our methods, documentation, team work, and output
Team work skills and tools (VCS, communicating, project management, etc.)
Documentation and Reporting
Properly
:)
maybe even with LaTeX :D
Yeah that's the gist of whats on my mind at the moment regarding an ideal computer science education
At least the foundations
The rest I leave it to the next dude. -
First week at the University, i became a circular mail with an offer for a place in the webteam. Requirements were a basic knowledge in linux/ubuntu and its packagemanagement and also some minor basics with nginx.
one day later i decides to mail my interest and that i mostly self-taughted me using linux since some years and began programinga year ago with python and recently deployed my first project in a VPS with nginx.
either, my qualification is quite high for that job or i was the one and only applicant, but who cares, i'm in.
this is my first employment in the it area,so i'm quite exited, even its mostly an administrative position. i gonne administrate the vm's for some websites and a special portal for students.
but! due to the fusion of two faculties at my university, there will also be two websites to be merged( our is on zope/plone and the other is a typo3) (computer science vs media... no really^^
well, now i have to wait for the doodle for the first meeting -
Not really a story about getting hacked, more like a story about my stupidity lol.
I had a friend whom at the time was taking a Computer Science course. And I had the basic daily-use computer knowledge, aka almost none. I was also very naive.
We were playing Maple Story and suddenly everytime I wrote something in the chat a 0 would appear in between some letters. I honestly thought he was messing around with my computer because earlier he had sent me a file through MSN.
So I told him several times to stop and he insisted that he wasn't doing anything.
A few minutes later, when I was finally able to stop laughing, I looked down to the keyboard and realized that the 0 key was stuck... I began laughing even harder. -
Critical Tips to Learn Programming Faster Sample:
Be comfortable with basics
The mistake which many aspiring students make is to start in a rush and skip the basics of programming and its fundamentals. They tend to start from the comparatively advanced topics.
This tends to work in many sectors and fields of Technology, but in the world of programming, having a deep knowledge of the basic principles of coding and programming is a must. If you are taking a class through a tutor and you feel that they are going too fast for your understanding, you need to be firm and clear and tell them to go slowly, so that you can also be on the same page like everyone else
Most often than not, many people tend to struggle when they reach a higher level with a feeling of getting lost, then they feel the need to fall back and go through basics, which is time-consuming. Learning basics well is the key to be fast and accurate in programming.
Practice to code by hand.
This may sound strange to some of you. Why write a code by hand when the actual work is supposed to be done on a computer? There are some reasons for this.
One reason being, when you were to be called for an interview for a programming job, the technical evaluation will include a hand-coding round to assess your programming skills. It makes sense as experts have researched and found that coding by hand is the best way to learn how to program.
Be brave and fiddle with codes
Most of us try to stick to the line of instructions given to us by our seniors, but it is extremely important to think out of the box and fiddle around with codes. That way, you will learn how the results get altered with the changes in the code.
Don't be over-ambitious and change the whole code. It takes experience to reach that level. This will give you enormous confidence in your skillset
Reach out for guidance
Seeking help from professionals is never looked down upon. Your fellow mates will likely not feel a hitch while sharing their knowledge with you. They also have been in your position at some point in their career and help will be forthcoming.
You may need professional help in understanding the program, bugs in the program and how to debug it. Sometimes other people can identify the bug instantly, which may have escaped your attention. Don't be shy and think that they'll make of you. It's always a team effort. Be comfortable around your colleagues.
Don’t Burn-out
You must have seen people burning the midnight oil and not coming to a conclusion, hence being reported by the testing team or the client.
These are common occurrences in the IT Industry. It is really important to conserve energy and take regular breaks while learning or working. It improves concentration and may help you see solutions faster. It's a proven fact that taking a break while working helps with better results and productivity. To be a better programmer, you need to be well rested and have an active mind.
Go Online
It's a common misconception that learning how to program will take a lot of money, which is not true. There are plenty of online college courses designed for beginner students and programmers. Many free courses are also available online to help you become a better programmer. Websites like Udemy and programming hub is beneficial if you want to improve your skills.
There are free courses available for everything from [HTML](https://bitdegree.org/learn/...) to CSS. You can use these free courses to get a piece of good basic knowledge. After cementing your skills, you can go for complex paid courses.
Read Relevant Material
One should never stop acquiring knowledge. This could be an extension of the last point, but it is in a different context. The idea is to boost your knowledge about the domain you're working on.
In real-life situations, the client for which you're writing a program for possesses complete knowledge of their business, how it works, but they don't know how to write a code for some specific program and vice versa.
So, it is crucial to keep yourself updated about the recent trends and advancements. It is beneficial to know about the business for which you're working. Read relevant material online, read books and articles to keep yourself up-to-date.
Never stop practicing
The saying “practice makes perfect” holds no matter what profession you are in. One should never stop practicing, it's a path to success. In programming, it gets even more critical to practice, since your exposure to programming starts with books and courses you take. Real work is done hands-on, you must spend time writing codes by hand and practicing them on your system to get familiar with the interface and workflow.
Search for mock projects online or make your model projects to practice coding and attentively commit to it. Things will start to come in the structure after some time.4
