Let the student use their own laptops. Even buy them one instead of having computers on site that no one uses for coding but only for some multiple choice tests and to browse Facebook.
Teach them 10 finger typing. (Don't be too strict and allow for personal preferences.)
Teach them text navigation and editing shortcuts. They should be able to scroll per page, jump to the beginning or end of the line or jump word by word. (I am not talking vi bindings or emacs magic.) And no, key repeat is an antifeature.
Teach them VCS before their first group assignment. Let's be honest, VCS means git nowadays. Yet teach them git != GitHub.
Teach git through the command line. They are allowed to use a gui once they aren't afraid to resolve a merge conflict or to rebase their feature branch against master. Just committing and pushing is not enough.
Teach them test-driven development ASAP. You can even give them assignments with a codebase of failing tests and their job is to make them pass in the beginning. Later require them to write tests themselves.
Don't teach the language, teach concepts. (No, if else and for loops aren't concepts you god-damn amateur! That's just syntax!)
When teaching object oriented programming, I'd smack you if do inane examples with vehicles, cars, bikes and a Mercedes Benz. Or animal, cat and dog for that matter. (I came from a self-taught imperative background. Those examples obfuscate more than they help.) Also, inheritance is overrated in oop teachings.
Functional programming concepts should be taught earlier as its concepts of avoiding side effects and pure functions can benefit even oop code bases. (Also great way to introduce testing, as pure functions take certain inputs and produce one output.)
Focus on one language in the beginning, it need not be Java, but don't confuse students with Java, Python and Ruby in their first year. (Bonus point if the language supports both oop and functional programming.)
And for the love of gawd: let them have a strictly typed language. Why would you teach with JavaScript!?
Use industry standards. Notepad, atom and eclipse might be open source and free; yet JetBrains community editions still best them.
For grades, don't your dare demand for them to write code on paper. (Pseudocode is fine.)
Don't let your students play compiler in their heads. It's not their job to know exactly what exception will be thrown by your contrived example. That's the compilers job to complain about. Rather teach them how to find solutions to these errors.
Teach them advanced google searches.
Teach them how to write a issue for a library on GitHub and similar sites.
Teach them how to ask a good stackoverflow question :>6 -
NEW 6 Programming Language 2k16
1. Go
Golang Programming Language from Google
Let's start a list of six best new programming language and with Go or also known by the name of Golang, Go is an open source programming language and developed by three employees of Google and the launch in 2009, very cool just 3 people.
Go originated and developed from the popular programming languages such as C and Java, which offers the advantages of compact notation and aims to keep the code simple and easy to read / understand. Go language designers, Robert Griesemer, Rob Pike and Ken Thompson, revealed that the complexity of C ++ into their main motivation.
This simple programming language that we successfully completed the most tasks simply by librariesstandar luggage. Combining the speed of pemrogramandinamis languages such as Python and to handalan of C / C ++, Go be the best tools for building 'High Volume of distributed systems'.
You need to know also know, as expressed by the CTO Tokopedia namely Mas Leon, Tokopedia will switch to GO-lang as the main foundation of his system. Horrified not?
eh not watch? try deh see in the video below:

2. Swift
Swift Programming Language from Apple
Apple launched a programming language Swift ago at WWDC 2014 as a successor to the Objective-C. Designed to be simple as it is, Swift focus on speed and security.
Furthermore, in December 2015, Swift Apple became open source under the Apache license. Since its launch, Swift won eye and the community is growing well and has become one of the programming languages 'hottest' in the world.
Learning Swift make sure you get a brighter future and provide the ability to develop applications for the iOS ecosystem Apple is so vast.

3. Rust
Rust Programming Language from Mozilla
Developed by Mozilla in 2014 and then, and in StackOverflow's 2016 survey to the developer, Rust was selected as the most preferred programming language.
Rust was developed as an alternative to C ++ for Mozilla itself, which is referred to as a programming language that focus on "performance, parallelisation, and memory safety".
Rust was created from scratch and implement a modern programming language design. Its own programming language supported very well by many developers out there and libraries.
4. Julia
Julia Programming Language
Julia programming language designed to help mathematicians and data scientist. Called "a complete high-level and dynamic programming solution for technical computing".
Julia is slowly but surely increasing in terms of users and the average growth doubles every nine months. In the future, she will be seen as one of the "most expensive skill" in the finance industry.
5. Hack
Hack Programming Language from Facebook
Hack is another programming language developed by Facebook in 2014.
Social networking giant Facebook Hack develop and gaungkan as the best of their success. Facebook even migrate the entire system developed with PHP to Hack
Facebook also released an open source version of the programming language as part of HHVM runtime platform.
6. Scala
Scala Programming Language
Scala programming termasukbahasa actually relatively long compared to other languages in our list now. While one view of this programming language is relatively difficult to learn, but from the time you invest to learn Scala will not end up sad and disappointing.
The features are so complex gives you the ability to perform better code structure and oriented performance. Based programming language OOP (Object oriented programming) and functional providing the ability to write code that is capable of evolving. Created with the goal to design a "better Java", Scala became one behasa programming that is so needed in large enterprises.3 -
University, first year. I went to my Java/OOP teacher's office to about the course (I had started programming C++ ~5 years ago).
I wanted to discuss the fact that some parts of the course seemed too theoretical for beginners in my opinion. Rookie mistake : do not criticize the cursus of an academic if you are in your first year, even when you are right. I learned it the hard way...
The teacher started to tell me that I was just a first-year student, I had no experience yada yada...
To that I replied "I'm doing C++ for 5 years. This is OOP so yeah I do know a little more than you think".
I will never forget his reply "LOL C++ is not Object-Oriented !"
I never went to his course after that. I learned a few years later that the teacher was a well-known a**hole along his peers and got fired by the University...40 -
I'm not qualified to say anything here, I'm a junior as well, but something general that I picked up:
Not everything needs to be object oriented.
Writing 5 functions and calling it a day is often much better than needing 13 classes and 4 interfaces.5 -
When I was in college OOP was emerging. A lot of the professors were against teaching it as the core. Some younger professors were adamant about it, and also Java fanatics. So after the bell rang, they'd sometimes teach people that wanted to learn it. I stayed after and the professor said that object oriented programming treated things like reality.
My first thought to this was hold up, modeling reality is hard and complicated, why would you want to add that to your programming that's utter madness.
Then he started with a ball example and how some balls in reality are blue, and they can have a bounce action we can express with a method.
My first thought was that this seems a very niche example. It has very little to do with any problems I have yet solved and I felt thinking about it this way would complicate my programs rather than make them simpler.
I looked around the at remnants of my classmates and saw several sitting forward, their eyes lit up and I felt like I was in a cult meeting where the head is trying to make everyone enamored of their personality. Except he wasn't selling himself, he was selling an idea.
I patiently waited it out, wanting there to be something of value in the after the bell lesson. Something I could use to better my own programming ability. It never came.
This same professor would tell us all to read and buy gang of four it would change our lives. It was an expensive hard cover book with a ribbon attached for a bookmark. It was made to look important. I didn't have much money in college but I gave it a shot I bought the book. I remember wrinkling my nose often, reading at it. Feeling like I was still being sold something. But where was the proof. It was all an argument from authority and I didn't think the argument was very good.
I left college thinking the whole thing was silly and would surely go away with time. And then it grew, and grew. It started to be impossible to avoid it. So I'd just use it when I had to and that became more and more often.
I began to doubt myself. Perhaps I was wrong, surely all these people using and loving this paradigm could not be wrong. I took on a 3 year project to dive deep into OOP later in my career. I was already intimately aware of OOP having to have done so much of it. But I caught up on all the latest ideas and practiced them for a the first year. I thought if OOP is so good I should be able to be more productive in years 2 and 3.
It was the most miserable I had ever been as a programmer. Everything took forever to do. There was boilerplate code everywhere. You didn't so much solve problems as stuff abstract ideas that had nothing to do with the problem everywhere and THEN code the actual part of the code that does a task. Even though I was working with an interpreted language they had added a need to compile, for dependency injection. What's next taking the benefit of dynamic typing and forcing typing into it? Oh I see they managed to do that too. At this point why not just use C or C++. It's going to do everything you wanted if you add compiling and typing and do it way faster at run time.
I talked to the client extensively about everything. We both agreed the project was untenable. We moved everything over another 3 years. His business is doing better than ever before now by several metrics. And I can be productive again. My self doubt was over. OOP is a complicated mess that drags down the software industry, little better than snake oil and full of empty promises. Unfortunately it is all some people know.
Now there is a functional movement, a data oriented movement, and things are looking a little brighter. However, no one seems to care for procedural. Functional and procedural are not that different. Functional just tries to put more constraints on the developer. Data oriented is also a lot more sensible, and again pretty close to procedural a lot of the time. It's just odd to me this need to separate from procedural at all. Procedural was very honest. If you're a bad programmer you make bad code. If you're a good programmer you make good code. It seems a lot of this was meant to enforce bad programmers to make good code. I'll tell you what I think though. I think that has never worked. It's just hidden it away in some abstraction and made identifying it harder. Much like the code methodologies themselves do to the code.
Now I'm left with a choice, keep my own business going to work on what I love, shift gears and do what I hate for more money, or pivot careers entirely. I decided after all this to go into data science because what you all are doing to the software industry sickens me. And that's my story. It's one that makes a lot of people defensive or even passive aggressive, to those people I say, try more things. At least then you can be less defensive about your opinion.53 -
So, I just started learning OOP(Object-Oriented Programming) and my brain hurts. like I maybe understood 10% of the information I just consumed. Is that a thing? Is OOP hard for people the first time around? Am I just dumb? Hell, it wouldn't be the first time14

Something that really bothers me about the oop idea of "oop allows better code reuse" is the fact that I have yet to encounter a situation where I need to reuse old code for a new project.
And the code I do want to reuse I've put into a library and made genetic anyway. Something which can easily be done with any language supporting generic programming, object oriented or otherwise.6 -
Java is an Object Oriented Programming (OOP) language created by James Gosling of Sun Microsystems. JavaScript is a scripting language that was created by the fine people at Netscape and was originally known as LiveScript. JavaScript is a (very) distant cousin of Java in that it is also an OOP language. Many of their programming structures are similar. However, JavaScript contains a much smaller and simpler set of commands than does Java.
Now let's talk about how Java and JavaScript differ. The main difference is that Java can stand on its own while JavaScript must (primarily) be placed inside an HTML document to function. Java is a much larger and more complicated language that creates "standalone" applications. A Java "applet" (so-called because it is a little application) is a fully contained program. JavaScript is text that is fed into a browser that can interpret it and then it is enacted by the browser--although today's web apps are starting to blur the line between traditional desktop applications and those which are created using the traditional web technologies: JavaScript, HTML and CSS.3 -
I've spent a lot of time messing around with C, having struggled with object-oriented programming (due to not really knowing how best to structure things, not knowing when to apply certain design patterns).
When writing C code, I'd write OOP-esque code (pass around a struct to routines to do things with it) and enjoyed just making things happen without having to think too much about the overall design. But then I'd crave being able to use namespaces, and think about how the code would be tidier if I used exceptions instead of having every routine return an error code...
Working with Python and Node over the past couple of years has allowed me to easily get into OOP (no separate declaration/definition, loose typing etc.) and from that I've made some fairly good design decisions. I'd implemented a few design patterns without even realising which patterns they were - later reading up on them and thinking "hey, that's what I used earlier!"
I've also had a bit of an obsession with small executable files - using templates and other features of C++ add some bloat (on Windows at least) compared to C. There were other gripes I had with C++, mostly to do with making things modular (dynamic linking etc.) but really it's irrelevant/unreasonable.
And yes, for someone who doesn't like code bloat, working with Node is somewhat ironic... (hello, node_modules...)
So today I decided to revisit C++ and dust off my old copy of C++ in a Nutshell, and try to see if I could write some code to do things that I struggled with before. One nice thing is that this book was printed in 2003, yet all of its content is still relevant. Of course, there are newer C++ standards, but I can happily just hack away and avoid using anything that has been deprecated.
One thing I've always avoided is dynamic_cast because every time I read about it, I read that "it's slow". So I just tried to work around it when really if it's the right tool for the job, I might as well use it... It's really useful!
Anyway, now I've typed all this positivity about C++ I will probably find a little later on that I hit a wall with what I'm doing and give up again... :p7 -
One of the things that I like the most regarding Clojure(and most Lisps to be honest) is how "not for beginners" the ecosystem feels.
Don't get me wrong, setting up a project in lein with dependencies(both internal and external) is a cakewalk, installing lein or boot is a cakewalk. Setting environment consts and middleware etc etc is a cakewalk.
Its just that there are no blogs about convoluted and amateurish ways of doing things. Most presentations and articles are written by really experienced and talented individuals.
I dunno, its just a nice shift in community. Its nice to see people not fucking up Object Oriented programming in java or any of the other oop languages. Its nice not seeing people giving horrible advice regarding memory management in C or c++ and it is sure as shit nice to not see spaghetti php und js code.
And my productivity levels are off the charts man. Really liking this shit and I get to stay inside my JVM -
I have lately seen a lot of people mentioning that functional programming is better than object oriented programming.
So far I have only experience in oop and I would really like to know some reasons why it is better.9 -
Went shopping with my girlfriend the other day and saw one of the sizes was OOP
I immediately asked out loud: “Object Oriented Programming?”3 -
I dont understand why we must use PHP to
understand OOP
Im a student software developer and this is the first time i will learn about Object Oriented programming but i dont know man im really confused why our prof makes us use PHP to understand the concept of OOP rather than to learn Python or Java which is ten times easier for an OOP based application
I can understand that PHP can be used for OOP but why just why... can someone please explain why this might be and how does it feel to use PHP for OOP purpouses9 -
Okay so theres something stopping me from understanding how Object Oriented Programming works. im sorry ahead of time this will get messy..
SO in this case we will use python. well what if the object has more than two functions? like the __init__, func1, then func2 and func2 does something else but doesn't get called or would you have to call of of them like class.func1(), class.func2().
I just don't understand when it comes to how the functions interact or effect each other. and how they would work when you dont call that specific function. I see the use of oop i just cant wrap my head around certain things..15 -
Still as a scholar who has had his intership I decided that I was finally confident enough in my ability to apply for a small part-time programming job. I had an internship at a cool exhausting place with tons of expertise and I've proven myselve over there. So now I wanted a job on the side. Nothing special, just something that would make a little money with programming instead of washing dishes at the restaurant.
So I started at this small internet based startup (2 or 3 progammers) as a backend-oriented programmer. The working hours were amazingly compatible with my school schedule.
The lead dev also sounded like a smart guy. He had worked as a backend guy for years and had code running on verry critical public infrastructure that if it were to fail we'd be evacuated from our homes.
As a first asignment I got an isolated task to make an importer for some kind of file format that needed integration. So I asked for access to the code. I didn't get it since they were going to re-do the entire backend based on the code I wrote. I just needed to parse the file in a usable object structure. So I found out that the file format was horrible and made a quite nice set of objects that were nice. At the end of the first week or so I asked if I could get access to the code again, so I could integrate it. Answer was no. The lead dev would do that. I could however get access to my private repository.
Next week a new intern was taken to build a multiplatform responsive app. Only downside was that all the stuff he had ever done was php based websites. It wasn't going anywhere anytime soon, but I figured that that was where internships were for. So I ended up helping him a lot and taught him some concepts of OOP and S.O.L.I.D. and the occasional 30 minute rants of IndexOutOfRangeException, ArgumentException and such.
So one day he asked me how to parse a json string and retrieve a specific field out of it.
I gave him something like the following to start with:
"
JObject json;
if(!JObject.TryParse(jsonString, out json))
{
//handle error
}
string value;
if(!json.tryget("foo", out value).../// code continues
"
but then the main dev stepped in and proposed the following since it wouldn't crash on an API change:
"
dynamic json = new JObject(jsonString);
string value = json.myJsonValue;
"
After me trying to explain to him that this was a bad choise for about 15 minutes because of all kinds of reasons I just gave up. I was verry mad that this young boy was forced to use bad programming pracises while he was clearly still learning. I know I shouldn't pick up certain practises. But that boy didn't.
Almost everytime the main dev was at the office I had such a mindboggling experience.
After that I got a new assignment.
I had to write another xml file format parser.
Of course I couldn't have any access to our current code because... it was unnecesary. We were going to use my code as a total replacement for the backend again.
And for some reason classes generated from XSD weren't clear enough so after carefull research I literally wrapped xsd generated code in equivalent classes.
At that moment, I realized I made some code that was totally useless since it wasn't compatible with any form of their API or any of the other backend code. (I haven't seen their API. I didn't have access to the source.) And since I could've just pushed them generated XSD's that would've produced thesame datastructure I felt like I was a cheat. I also didn't like that I wasn't allowed to install even the most basic tooling. (git client or, Ide refactoring plugins, spelling checker etc...)
Now I was also told that I couldn't discuss issues with the new guy anymore since it was a waste of my valuable time, and they were afraid that I taught him wrong concepts.
This was the time that my first paycheck came in so I quitted my job.
I haven't seen any of the features that I've worked on. :)
