I've found sites like Udemy/Khanacademy/Codecademy/Brilliant/Edx to be very useful — possibly more useful than expensive education.

But they still need:

1. Better correction/update mechanisms. Human teachers make mistakes and material gets outdated, and while online teachers are rectified faster than classroom teachers, the procedure is still not optimal. Knowledge should be a bit more like a verified wiki.

2. Some have great interactive coding environments, some have great videos, some have awesome texts, some have helpful communities. None has it all. In the end, I don't want to learn a new language by writing code in my browser. It could all be integrated/synced to the point where IDEs have plugins which are synced to online videos, with tests and exercises built in, up to a social network where you could send snippets for review and add reviews to other people's code.

3. Accreditation. Some platforms offer this against payment, but I think those platforms often feel very old school (pun intended), with fixed schedules, marks and enrollments. Self paced is a must.

4. Depth is important. Current online courses are often a bit introductory. We need more advanced courses about algorithms, theoretical computer science, code design, relational algebra, category theory, etc. I get that it's about supply/demand, but we will eventually need to have those topics covered.

I do believe that for CS, full online education will eventually win from the classroom — it's still in its infancy, but has more potential to grow into correct, modern education.

Still trying to get good.

The requirements are forever shifting, and so do the applied paradigms.

I think the first layer is learning about each paradigm.

You learn 5-10 languages/technologies, get a feeling for procedural/functional/OOP programming. You mess around with some electronics engineering, write a bit of assembly. You write an ugly GTK program, an Android todo app, check how OpenGL works. You learn about relational models, about graph databases, time series storage and key value caches. You learn about networking and protocols. You void the warranty of all the devices in your house at some point. You develop preferences for languages and systems. For certain periods of time, you even become an insufferable fanboy who claims that all databases should be replaced by MongoDB, or all applications should be written in C# -- no exceptions in your mind are possible, because you found the Perfect Thing. Temporarily.

Eventually, you get to the second layer: Instead of being a champion for a single cause, you start to see patterns of applicability.

You might have grown to prefer serverless microservice architectures driven by pub/sub event busses, but realize that some MVC framework is probably more suitable for a 5-employee company. You realize that development is not just about picking the best language and best architecture -- It's about pros and cons for every situation. You start to value consistency over hard rules. You realize that even respected books about computer science can sometimes contain lies -- or represent solutions which are only applicable to "spherical cows in a vacuum".

Then you get to the third layer: Which is about orchestrating migrations between paradigms without creating a bigger mess.

Your company started with a tiny MVC webshop written in PHP. There are now 300 employees and a few million lines of code, the framework more often gets in the way than it helps, the database is terribly strained. Big rewrite? Gradual refactor? Introduce new languages within the company or stick with what people know? Educate people about paradigms which might be more suitable, but which will feel unfamiliar? What leads to a better product, someone who is experienced with PHP, or someone just learning to use Typescript?

All that theoretical knowledge about superior paradigms won't help you now -- No clean slates! You have to build a skyscraper city to replace a swamp village while keeping the economy running, together with builders who have no clue what concrete even looks like. You might think "I'll throw my superior engineering against this, no harm done if it doesn't stick", but 9 out of 10 times that will just end in a mix of concrete rubble, corpses and mud.

I think I'm somewhere between 2 and 3.

I think I have most of the important knowledge about a wide array of languages, technologies and architectures.

I think I know how to come to a conclusion about what to use in which scenario -- most of the time.

But dealing with a giant legacy mess, transforming things into something better, without creating an ugly amalgamation of old and new systems blended together into an even bigger abomination? Nah, I don't think I'm fully there yet.

Hello everyone, this is my first time here so hi! I want to tell you all a story about my current situation.

At 18 while in the military I was able to get my first computer, it was a small hp pavilion laptop with windows 7. The system would crash constantly, even though I would only use it for googling stuff and using fb to talk to people. 5 months after I got it and continuously hated it decided to find out why and who could I blame (other than myself) for the system making me do the ctrl alt del dance all the time....

Found out that there are people called computer programmers that made software. Decided to give it a go since I had some free time most days. Started out with c++ because it was being recommended in some websites. Had many "oh deeeeer lord" moments. After not getting much traction I decided to move to Java which seemed like an easier step than C++. Had fun, but after some verbosity I decided to move into more dynamic lands. Tried JS and since at the time there was no Node and I was not very into the idea of building websites I decided to move into Python, Ruby, PHP and Perl and had a really great time using and learning all of them. I decided to get good in theoretical aspects of computer programming and since I had a knack for math I decided to get started with basic computer science concepts.

I absolutely frigging loved it. And not only that, but learning new things became an obsession, the kind that would make me go to bed at 02:40 am just to wake up at 04:00 or 06:00 because the military is like that. I really wanted to absorb as much as I could since I wanted to go to college for it and wanted to be prepared since I did not wanted to be a complete newb. Took Harvard CS50, Standford Programming 101 with Java, Rice's Python course and MIT's Python programming class. I had so much fun I don't regret it one bit.
By the time I got to college I had already made the jump to Linux and was an adept Arch user, Its not that it was superior or anything, but it really forced me to learn about Linux and working around a terminal and the internals of the system to get what I want. Now a days I settle for Fedora or Debian based systems since they are easier and time is money.

Uni was a breeze, math was fun and the programming classes seemed like glorified "Hello World" courses. I had fun, but not that much fun, most of my time was spent getting better at actual coding. I am no genius, nor my grades were super amazing(I did graduate with honors though) but I had fun, which never really happened in school before that.

While in school I took my first programming gig! It was in ASP.NET MVC, we were using C#, I got the job through a customer that I met at work, I was working in retail during the time and absolutely hated it. I remember being so excited with the gig, I got to meet other developers! Where I am from there aren't that many and most of them are very specialized, so they only get concerned with certain aspects of coding (e.g VBA developers.....) and that is until I met the lead dev. He was by far one of the biggest assholes I had ever met in my life. Absolutely nothing that I would do or say made hem not be a dick. My code was steady, but I would find bugs of incomplete stuff that he would do, whenever I would fix it he would belittle me and constantly remind me of my position as a "junior dev" in the company saying things as "if you have an issue with my code or standards tell me, but do not touch the code" which was funny considering that I would not be able to advance without those fixes. I quit not even 3 months latter because I could not stand the dick, neither 2 of the other developers since the immediately resigned after they got their own courage.

A year latter I was able to find myself another gig. I was hesitant for a moment since it was another remote position in which I had already had a crappy experience. Boy this one was bad. To be fair, this was on me since I had to get good with Lumen after only having some exposure to Laravel. Which I did mentioned repeatedly even though he did offer to train me in order to help him. Same thing, after a couple of weeks of being told how much I did not know I decided to get out.

That is 2 strikes.

So I waited a little while and took a position inside another company that was using vanilla PHP to build their services. Their system was solid though, the lead engineer remains a friend and I did learn a lot from him. I got contracted because they were looking for a Java developer. The salary was good. But when I got there they mentioned that they wanted a developer in Java...to build Android. At the time I was using Java with Spring so I though "well how hard can this be! I already use Android so the love for the system is there, lets do this!" And it was an intense, fun and really amazing experience.

-- To be continued.

I did a 3 years study in computer science.

I got an intern that is on her last year of a 5 years study in computer science too.

So we have the same age, just that I have more practical experiences than her and she have more theoretical baggage than me.

We are discussing on the design of what she will do over her internship and while I'm talking about some JSON modelling she interrupt me to say something like "so this tuple is meaning..." talking about a JSON object. I didn't get what she was talking about (I never did python and didn't learn much about mathematical theorems during my study) so I asked her: "What is a tuple?".. She looked at me with dead eyes saying "what!? you don't know this ?!!" Like I was the dumbest man on earth. Fortunately our PM which is also a coding guy was sitting next to us and explained to me that by saying "tuple" she meant a "JSON object" and to her that it IS normal if I do not know what a tuple is, first because of my studies, 2nd because my job is to be an Android Dev and that I do not need to know this to do my job. He added that by the way I'm doing well my job and that if I wasn't there to help her on her code she would never succeed her internship.

I'm glad my PM intervene but fuck those who always think they know everything better than others without questioning themselves before !

Appropriate for all ages

Most kids just want to code. So they see "Computer Science" and think "How to be a hacker in 6 weeks". Then they face some super simple algebra and freak out, eventually flunking out with the excuse that "uni only presents overtly theoretical shit nobody ever uses in real life".

They could hardly be more wrong, of course. Ignore calculus and complexity theory and you will max out on efficiency soon enough. Skip operating systems, compilers and language theory and you can only ever aspire to be a script kiddie.
You can't become a "data scientist" without statistics. And you can never grow to be even a mediocre one without solid basic research and physics training.

Hack, I've optimized literal millions of dollars out of cloud expenses by choosing the best processors for my stack, and weeks later got myself schooled (on devRant, of all places!) over my ignorance of their inner workings. And I have a MSc degree. Learning never stops.

So, to improve CS experience in uni? Tear down students expectations, and boil out the "I just wanna code!" kiddies to boot camps. Some of them will be back to learn the science. The rest will peak at age 33.

Why do theoretical computer science and maths lectures mostly start at 8 am. I am a nocturnal creature to me is like having to wake up at 3 am for others. There are other kinds of people that like to get up early so here is a suggestion: Why don't we agree that all lectures start at 11:00 earliest? It is a good time in the day for a lot of people and I would have the time to inject myself with some Mate tea.

Last week I wired up my home network (including custom modem and routers) myself, because the stuff my ISP wanted me to use was garbage.
Luckily Germany has "router-freedom" so ISPs are not allowed to force us to use their device to dial into the network.
I did everything myself, because the 'technicians' they kept sending me were just idiots who didn't know anything, considering the highly paid job they are doing. Usually they told me, to get the device from my ISP, because my "Router" (actually a business grade, standalone Modem by Cisco, to feed my Router) didn't even have WiFi ( lol ). Also all Technicians didn't arrive at the agreed date but at some other time. I wasn't able to wait any longer.
So I did it myself.

Consider me something more like a student of theoretical computer science. Not actually supposed to be experienced with hardware stuff.

The ISP is serving me with a DOCSIS 3.0 Network based on the television cable network in my city. For some reason they are providing the internet-access to only one socket in the apartment, which has a rather uncommon "WICLIC" connector. After having trouble getting an adapter for WICLIC to common coaxial F-Connectors (used by every DOCSIS-Modem), I made one myself.

After setting up everything (not that hard, once the connectors fit) my modem told me, that, while I'm perfectly connected to the ISPs internal Network, I still can't access the internet.

So I called the ISP...
After getting ranted at, about that what I'm doing is illegal and only certified employees are allowed to do this and I will break more, than actually do good and that I can't just connect my own "Router" (again I needed to correct her: Modem) I hang up the phone.
Also she accused me of hacking their devices because I'm not supposed to see my IP address... (My Modem told me on its web interface. I didn't even need telnet for that.)
I went to the ISPs head office, told the first desk as many technical terms as I could remember and got forwarded to something like the main technician.

He was a really nice guy. The only sane and qualified person I dealt with at this company. He asked me for my Address and Device Model, I told him my MAC and last internal IP, I had seen and he activated my internet access within a minute.
We talked a while about the stupid connector that ISP is using in the homes and he gifted me some nicer adapters to connect my modem to the wall.

Why do ISPs hate their customers that much?

I'm not going to lie, the surge of bootcamps really irks me. Not because I'm afraid of competition, or that I'm an elitest. Mainly because a lot of people who attend these bootcamps have no real interest in software engineering. I sometimes attend a meetup, and it's a beginner meetup. I try to help out. And a lot of people clearly have no patience for learning software engineering. I try to be encouraging, but sometimes I just want to be dick and tell them "Why the hell do you want to be a dev, if you're not interested in how computers work".

I'm an 100% myself taught developer. Granted I'm 38 and taught myself programming at 14. But it came out of an earnest desire and love for technology in general. So I never shyed away from learning? C and assembler? Bring it on. Theoretical computer science? I can get with that. For me I loved computer so much, that I was willing to learn about anything in the realm of computing.

This is what annoys me with the adult bootcamp crowd. I feel they're only willing to learn as long as it's easy. If something gets complicated or complex, then they check out. And I a lot of their questions is "tell me how to do this/that". But they don't know why they would do it.

To me it feels like they're trying to fast track themselves to a dev job. Yet you would think if they're trying to do this all professionally, they would be open to learning as much as possible, and not closing themselves off.

My semi-friend who runs the meetup is trying to start a bootcamp himself. So I try I severely hold my tongue when I attend those meetups. And I want to be supportive. I certainly don't want to be the reason why people are turned off by programming. But at the same time, I hate how people are abusing this profession because they think it's fast money and an easy way to earn 6 figure salaries.

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.

Question: when modeling a language using a nondeterministic finite state machine, do I have to add a "trash" state, if a deterministic one would need one or can it just be obmited and if so why?

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.

Writing my master thesis at my company, theoretical computer science, doing fancy shit with scheduling rules. but am just a "working student".
Realized, that all my project member, also other colleagues, standing right behind me at a Whiteboard, discussing that part of the project I am the expert of, as this exactly is my topic.
They were asking very new team member about my topic, but they know nothing, just guessing how this could be.

Nobody did even think about asking me.
So I continued working on what they thought "nobody has knowledge about at all".

An excerpt from our script for theoretical computer science...
A really nice NFA xD

Theoretical Computer Scientist:
Somebody who produces exaggerating amounts of recycling paper.

Typically every computer science major begins with either C C# C++ java or python , creating so much abstraction from the hardware which just loads your mind with questions that remain unanswered.When ever i program something i always think of how the under lying stuff is working.They never explain how and where software meets the hardware.Why are they keeping students away from the hardware. I think a cs graduate without knowing the underpinning of a computer should not be considered a cs graduate as opposed to being a software engineer a computer science major relates to everything that is a computer that includes the theoretical stuff and a little bit know how of computer hardware. Instead of teaching this stuff and assembly as a language in the first semester they teach you java or C++. Could not speculate on why this is so.

Man I want to develop a software...got lots of idea and all( also got a computer science degree with all theoretical bullshit) how can I develop one from start to end....

What I hate the lost about exam season, is the lack of coding... Spend two months cramming all the theoretical parts of computer science, and it just gives no time to code

My CS (theoretical foundations of computer science, specifically) professor is currently teaching regular expressions... Has been for three weeks. Same thing over and over. All of his examples involve using regular expressions to parse HTML. He just told us to write a script (using Perl-style regex) that would recursively find and follow link tags in various websites. Just... no...
