Thread Rules
1. This is not a "do my homework for me" thread. If you have specific questions, ask, but don't post an assignment or homework problem and expect an exact solution.
2. No recruiting for your cockamamie projects (you won't replace facebook with 3 dudes you found on the internet and $20)
3. If you can't articulate why a language is bad, don't start slinging shit about it. Just remember that nothing is worse than making CSS IE6 compatible.
4. Use [code] tags to format code blocks. |

Since they have already told me that I will require to use multiple languages I'm unsure what I should concentrate on:
C would build foundations and I already have experience with it, the other two are closer to the actual work.
What would you learn and which books would you recommend? (would they be the same if you had just one month?)
PS: I'm absolutely aware that one month isn't enough to make me a programmer.
How the hell do you get recruited for something like that without having the required skills?
Either way, to my knowledge Java is the language of choice in the financial and insurance sector, so I'd start getting comfortable with that... fast. No use starting with C in that situation since you have to program stuff soon, not learn how stuff works.

As far as I'm aware they hired me mostly for my problem solving skill scoming from the physics side of things, not the programming.
thanks for the advice morfildur and spinesheath. now I only need a good Java book.

Yeah but once again - prof command, I follow  .
Regarding your code, I have a question, what does this exactly do/what it is called so I can lookup how it works/what is does.
Proxy(MatrixElement& element, int x): element(element), x(x) { }

PS: I'm absolutely aware that one month isn't enough to make me a programmer. Less than one month won't get you far; but if you know C++, you will be able to work with any other modern C language, including Java. So, in my opinion, go for C++. Personally I would recommend 'C++ Primer Plus' by Stephen Prata as an introduction to C++. It covers everything that you need to know to get things done in a very clear way... I also recommend 'The C++ Programming Language' by Stroustrup, BUT I think it's a better option as a second book. It's not very 'noob-friendly'. Also, two best reference websites for C++ are: http://www.cplusplus.com/http://en.cppreference.com/
While I agree on C++ Primer, I recommend the Effective C++ books after you finish reading it.

Proxy(MatrixElement& element, int x): element(element), x(x) { }
It's called an initialization list (not to be confused with an initializer list... <3 C++), and all it does is initialize those members to the specified values - so the new Proxy's 'element' member will be set to the 'element' argument, and the 'x' member will be set to the 'x' argument.
The names being the same in both args and members is confusing as hell, but not ambiguous because fuck you that's why 'Names in the expression-list of a mem-initializer are evaluated in the scope of the constructor for which the mem-initializer is specified.' which means this is okay.
Maybe clearer example:
class Proxy {
public:
// This constructor just copies the passed-in 'element' and 'x' into m_element and m_x
Proxy(MatrixElement& element, int x): m_element(element), m_x(x) { }
private:
MatrixElement m_element;
int m_x;
}

Late response because my RAM decided to die and to give me bluescreens en más. Did you knew that the windows built-in memtest is actually better then memtest86+? I didnt and it was driving me crazy that I was unable to detect the defective module. I was close to assuiming one of the slots was the problem.
Anyway, thanks for your response and kind help, I was able to complete the whole assignment. Despite my prof never checking them, it feels good

make sure you get the right primer, there is a useless one out there from different authors.

Sounds like I need to move to Germany if you don't even need to know how to program to get hired for programming, lol. No offence.
|
Yeah well, a german university degree in physics or math doesnt come for free, around 50% quit.
Its a bit unusual to make a consultant with that background actually program, though.
You can still come though, some areas of actual programming need more workers, payment in industrial jobs can be high.
Embedded systems, background in electronics, network stuff...
Just dont be a wannabe gamedev, appdev or webpage guy

Techniacally, you can be a webpage guy but make sure you get into SaaS instead of your normal web pages.

Plenty of physics graduates working as programmers where I am. Although I don't know anyone who got through university without doing at least some, mostly in Python though.
|
So what makes physicists go to computer science/programming? Is the professional field for physicists not well supported?
|
physicists are no engineers and at least during my search for a job I often thought: I could do/learn that but I bet they want a technical physicist or similar.
btw: thanks to all the others for the advice

pretty much need phd to do anything that really uses physics knowledge, just as in chemistry and biology.
Math is probably even worse.
University level physics has the most classes on calculating things than any other subject, including math, so often they are hired in businesses where you have to calculate complex things. Banks etc.
What he was hired for is normally attributed to math university graduents, the ability of creative problem solving, logic reasoning and abstraction, which math requires a lot of for proof construction etc.
What is weird is that he is now actually programming things, maybe the company is just weird :p
|
Some things for clarification: I wrote my master's thesis on QFT and my minor was mostly math. So I feel very much qualified on the math side of things.
And I'm not sure how much programming I will have to do, it's just that they asked for it in the interview and I said: I'm willing to do that.
So atm I'm just preparing the best I can. (which takes away on the programming side, b/c the financial book they recommended also has 700 pages.)

Well, if it'll cheer you up, here's a bit of a rough breakdown on employee education at the company I work at:
16 developers
6 have CS/IT education of varying levels
2 have degree in humanities (myself included, studied philosophy, history and settled on bachelor's degree in sociology after which I've lost my will to attend university any more since it was a waste of time)
The rest have no higher education (finished either highschool or its technical equivalent).

That's not so bad really. No higher education doesn't mean they have no experience in programming. Lots of people do it in their spare time after all.
Unless you mean to tell me most of these were people without experience in programming as well.

I'd love to beef up my maths skills as a software development/computer science graduate just to have an extra edge against competition. Any recommendation where to start from or topics?
Edit: I'm working as a software engineer but I'm not planning to go maths full time. Just learning some more maths as a hobby.

university math is extremely against human nature, in my oppinion you need a person explaining the concepts and assisting people and most importantly constantly correcting mistakes in proofs.
There is probably a standard book collection for any language, might try one of those, but might not work out.
