What container data structures do all of you actually use?

For me, I'd say: dynamically sized array, hashtable, and hash set. (And string if you count that.)

In the past 8 months, I've used another container type maybe once?

Meanwhile, I remember in school, we had all these classes on all these fancy data structures, I havent seen most of them since.

I have lost track of the whys, but I'm writing something that loads a datastructure not unlike specifications of C types (plus struct single inheritance and generics) from any DLL-s tossed in the same folder, then organizes them into a pretty database. Now I just gotta keep gradually broadening the scope until I get to the feature set of the modern C# type system.

Noob alert !

Plz feed me some c# projects!!

Mayn i ve been only reading and learning from book(c# 7.0 in a nutshell) i feel like i need to implement the stuff i learned so paliz help me daddy !
Again i am noob simple uni projects would be fine!
Projects with oop datastructure and simple database would do the job!

But if you have better suggestions feed me !

Thanks :)

I'm hurtling down the Dunning Kruger slope in Rust datastructure design. The orchidlang crate has a struct that attempts to wrap and replicate a slice for no reason other than to attach some domain-specific methods and a custom Display implementation. I came up with 4 different representations for a file URI as provided by the language client. The most recent one holds a singular string in an Arc. I know that these are bad ideas but I don't know why I keep coming up with them.

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. :)

Hate when a new feature requested by betatester require to change the datastructure. Those feature that force you to start a refactoring while u still in betatesting. Are good in a way, but so much frustrating to get back to alfa or in dev phase while u were just happy that this project came to an end and delivered

Hi everyone! I'm in need of some help regarding the approach to my bachelor thesis.

The practical stuff is basically clickstream/task and usability analysis on an existing platform and creating mockup improvements for some processes. I was thinking about using a spider to generate a tree (or another datastructure) regarding all the different tasks available and then trying to optimise said tree, thus automatically optimising the processes within. I'm having however issues imagining how this optimisation might be generalised for more than this one platform.

Basically, I'm a bit lost and grasping for any pointers in any direction regarding these ideas.

Looking at @striker28 's rant made me think of my time I did my MSc and I think it needs it's own separate rant so here it goes:

So I did an MSc at one of the big league unis in London. First clue was during week 1 where in one of the class a mature student asked whether there would be actual coding during the course. There was an audible gasp from everyone else! Once the lecturer said the unfortunatly they wouldn't be you could hear the sigh of relief from the students...

Next up was all the lectures being placed in the freakin' basement of the university in crap, smelly rooms with annoying ticking A/Cs whereas all the social siences, business and other subjects had lecture halls and classrooms above ground. The contempt for CS from the university's direction was palpable.

Then there was the relegation to the theory-only (i.e. abstract with pen/paper) "tutorial" to the hand of T/As with bugger-all teaching experience. In short most were terrible and should've found a way to abscond themselved from this obligation which was part of the terms of their phd grants unfortunatly.

Further into the course there was the "group project". Oh boy! Out of the 5 in the group my now mature student friend and I were the only one commiting to the repo. There was either no code and a lot of bullshit from the others or crap code that didn't even compile despite their assurances it was all good.. Someone clearly never actually coded and pressed "run" in their lives which is fucking surprising since they've managed to graduate with a BSc and get into a MSc somehow. None of the code "made" by the other 3 persons made it into the master branch for release.
The attitude was that of "We (hahahah) wrote loads of code. We'll get a great mark!". At that stage the core wasn't even complete and the software didn't work yet.

Some of the courses where teaching things already 10 years out of date and when lecturer where pressed on that the few mature students that happen to be there the answer was always "yes, we are planning to update it for next year". Complete bullshit. Didn't help that some of the code on the lecture slides was not even correct! I mean these guy are touted as "experts" in their field...

None of the teory during the entire year was linked to any coding. Everything was abstract with no ties to applied software engineering. I.e. nothing like the real world.

The worst is that none of the youger students realised they were being screwed over and getting very little value for their money. Perhaps one reason why these evaluation forms have such high scores given on them. If you haven't had a job and haven't lived outside academia yet there is nothing to compare it to. It tends to also fall into confirmation bias (hey it's a top UK university, it must be worth it afterall! Look how much they ask for).

By the end of the year I couldn't wait to get the hell out. One of the other mature student sumed it quite well: "I will never send my children here."
Keep in mind that the guy had just over a decade of software engineering experience in the industry and was doing this for fun.

In the end universities are not teaching institutions. The lecturers's primary job is research and their priorities match that. Lectures tend to be the most time efficient teaching format for the ones giving them but, on their own, are not for the consumer.

To those contemplating university for CS: Do the BSc. Get your algo/datastructure chops and learn the basic theory. It is interesting. Don't get discouraged by the subject just because it is taught badly.
Avoid the MSc unless you want to do a phd and go for an academic carrer. You are better off using that year and the money to learn more on your own and get into colaborative projects (open source) on top of some personal ones. Build up your portfolio. It will be cheaper and more interesting!

Sorry :(
