  • What are some recommended video lectures for a non-CS student to prepare for the GRE CS subject test?

    - by aristos
    Well the title kinda explains all there is to explain. I'm a non-cs student and was preparing to apply PhD programs in applied mathematics. But for my senior thesis I've been reading lots of machine learning and pattern recognition literature and enjoying it a lot. I've taken lots of courses with statistics and stochastics content, which I think, would help me if I get accepted to a program with ML focus, but there are only two CS courses -introduction to programming- in my transcript and therefore I decided to take the CS subject test to increase my chances. Which courses do you think would be most essential to have a good result from CS subject test? I'm thinking of watching video lectures of them, so do you have any recommendations?

  • What kind of an IT or programming job can a college student get part time?

    - by Alex Foster
    I'm a college student with a full load of classes and i need some extra money to cover some of my expenses. I love anything and everything to do with computers. I don't know how to program but have build computers before and know how windows works. I would call myself a power user. My question is, what kind of a job can someone like me get with effort? If there are some more skills that i can pick up that would benefit in getting the foot in the door i would love to hear about them. The only limitation i have is that i can't work very late in the evening most days due to classes. But usually in the morning my time is available for work. I will appreciate all answers i receive. Thank you for your help.

  • Tips for a first year CS student looking for a summer internship to gain experience?

    - by Matt
    Hello all, I am a first year CS student and my programming experience is only what I have obtained in my computer programming I and II classes this school year. (console applications in C++) I want to find a summer job/internship that would help me build my skill set. Being that I am still such a beginner pay is not a concern, minimum wage would be nice, but as long as I am learning, I really don't care. My current resume just lists a bunch of random jobs i've had in the past (burger king, summer camps, best buy, etc.) Does anyone have any tips (places to look? things to put on resume?) that might help me?

  • C# Winforms vs WPF

    - by m0s
    Hi pros, I am a student and I do freelance here and there when I have opportunity. I believe my strongest language is C#. I don't really know what is going on in real programming world, so I was wondering if WPF did take over WinForms? I know the differences between two and how two can be used simultaneously but, I just don't want to invest my time in learning dying technologies, I hope you understand. So, for windows desktop programming what would you recommend to master WinForms, WPF or maybe both? I also get a lot that desktop programming is dead already and one should only care about learning web programming. Thanks for attention, any comments are greatly appreciated.

  • DD-WRT/openwrt question

    - by Shiki
    Can I squeeze more speed out of my router (when it comes to USB attached storage device on it) with open/DD wrt? (Sorry I don't really know such firmwares.) (Guess it works with ntfs-3g? I don't know.) Feel free to make this a real question. Basically the question: Does the change worth it in the terms of speed? (My router is a TP-Link WR1043N. Edited it out of the question since it would make it too specified.)

  • Vector insert() causes program to crash

    - by wrongusername
    This is the first part of a function I have that's causing my program to crash: vector<Student> sortGPA(vector<Student> student) { vector<Student> sorted; Student test = student[0]; cout << "here\n"; sorted.insert(student.begin(), student[0]); cout << "it failed.\n"; ... It crashes right at the sorted part because I can see "here" on the screen but not "it failed." The following error message comes up: Debug Assertion Failed! (a long path here...) Expression: vector emplace iterator outside range For more information on how your program can cause an assertion failure, see the Visual C++ documentation on asserts. I'm not sure what's causing the problem now, since I have a similar line of code elsewhere student.insert(student.begin() + position(temp, student), temp); that does not crash (where position returns an int and temp is another declaration of a struct Student). What can I do to resolve the problem, and how is the first insert different from the second one?

  • question about chroot

    - by morpheous
    I used chroot to install Debian Lenny on my Ubuntu desktop. I have now decided I will no longer be using Debian and so I want to remove Debian and install Ubuntu server in a chroot instead. My question is, I can simply remove the /chroot/debian/lenny folder and create a new chroot for Ubuntu server? or is there something else I need to do (I have read a bit about chroot but it does not answer this question)

  • Question about RewriteRule and HTTP_HOST server variable

    - by SeancoJr
    In evaluating a rewrite rule that redirects to a specific URL and say the rewrite condition is met, would it be possible to use HTTP_HOST as part of the URL to be redirected to? Example in question: RewriteRule .*\.(jpg|jpe?g|gif|png|bmp)$ http://%{HTTP_HOST}/no-leech.jpg [R,NC] The motive behind this question is a desire to create a single htaccess file that would match against an addon domain (on a shared hosting account) and an infinite amount of subdomains below it to prevent hotlinking of images.

  • How can I help fellow students struggling in programming classes?

    - by David Barry
    I'm a computer science student finishing up my second semester of programming classes. I've enjoyed them quite a bit, and learned a lot, but it seems other students are struggling with the concepts and assignments more than I am. When an assignment is due, the inevitable group email comes out the day or two before with people needing some help either with a specific part of the problem, or sometimes people just seem to have a hard time knowing where to start. I'd really like to be able to help out, but I have a hard time thinking of the right way to give them help without giving them the answer. When I'm having trouble understanding a concept, a code snippet can go along way to helping me, but at the same time if it makes a lot of sense, it can be difficult to think of another way to go about it. Plus the Academic Integrity section of each assignment is always looming overhead warning against sharing code with others. I've tried using pseudo code to help give others an idea on program flow, leaving them to figure out how to implement certain aspects of it, but I didn't get too much feedback and don't know how much it actually helped them out, or if it just confused them further. So I'm basically looking to see if anyone has experience with this, or good ways that I can help out other students to nudge them in the right direction or help them think about the problem in the right way.

  • MySQL " identify storage engine statement"

    - by sammysmall
    This IS NOT a Homework question! While building my current student database project I realized that I may want to identify comprehensive information about a database design in the future. More-so if I am fortunate enough to get a job in this field and were handed a database project how could I break down certain elements for identification... In all of my previous designs I have been using MySQL Community Server (GPL) 5.1.42, I thought (duh) that I was using the MyISAM based on most of my text-book instruction and MySQL 5.0 Reference Manual :: 13 Storage Engines :: 13.1 The MyISAM Storage Engine I determined that this was in fact incorrect for this version and the use of "SHOW ENGINES" at the console... No problem, figured out why they have "versions" the need to pay attention to what version is being used, and the need for a means to determine what I am about to mess up "if" I do not pay attention to detail... Q1. Specifically what statement will identify the version used by someone elses initial database creation? (since I created my own databases I know what version I used) Q2. Specifically what statement will identify the storage engine that the developer used when creating the database. (I specified a particular database in my collection then tried SHOW Engine, did not work, then tried to just get the metadata from one table in that database: mysql SELECT duck_cust, table_type, engine - FROM INFORMATION_SCHEMA.tables - WHERE table_schema = 'tp' - ORDER BY table_type ASC, table_name DESC; as this was not really what I wanted (and did not work) I am looking for some direction from the pros... Q3. (If you really have the inclination to continue helping) If I were to access a database from an earlier/later "version" are there backward/forward compatibility issues for maintaining/updating data between versions? Please and Thank you in advance for your time and efforts! sammysmall

  • Advice on selecting programming languages to concentrate on? (2nd year IT security student)

    - by Tyler J Fisher
    I'm in the process of considering which programming languages I should devote the majority of my coding studies to. I'm a 2nd year CS student, majoring in IT security. What I want to do/work with: Intelligence gathering Relational databases Virus design Snort network IPS Current coding experience (what I'm going to keep): Java - intermediate HTML5 - intermediate SQL (MySQL, Oracle 11g) - basic BASH - basic I'm going to need to learn (at least) one of the following languages in order to be successful in my field. Languages to add (at least 1): Ruby (+Metasploit) C++ (virus design, low-level driver interaction, computationally intensive applications) Python (import ALL the things) My dilemma: If I diversify too broadly, I won't be able to focus on, and improve in a specific niche. Does anyone have any advice as to how I should select a language? What I'm considering + why I'm leaning towards Ruby because of Metasploit support, despite lower efficiency when compared to Python. Any suggestions based on real-world experience? Should I focus on Ruby, Python, or C++? Both Ruby, and Python have been regarded as syntactically similar to Java which my degree is based around. I'm going to be studying C++ in two years as a component of my malicious code class. Thanks, Tyler

  • How does a CS student negotiate in/after a job interview?

    - by Billy ONeal
    Alright, I've gotten to the second step in the interview process. At this point I'm working under the assumption that I might be offered a position -- flying my butt to Redmond would be quite an expense if they weren't at least considering me for something (*crosses fingers*). So, if one is offered a position, how should a CS student negotiate? I've heard a few strategies about dealing with software companies when you are being considered for a hire, but most of them are considering the developer in a powerful position. In such examinations, (s)he has lots of job experience, and may even be overqualified for what the employer is looking for. (s)he is part of a small job market of qualified developers, because 99% of applications companies receive are from those who are woefully under qualified. I'm in a completely different position. I think I compare favorably to most of my fellow students, and I have been a programmer for almost 10 years, but often I still feel green compared to most of my coworkers. I'm in a position where the employer holds most of the chips; they'd be doing me quite a favor by hiring me. I think this scenario is considerably different than the targets for most of the advice I've seen. Above all, I don't want to be such a prick negotiating that it damages my chances to actually operate in a position, even if it means not negotiating at all. How should one approach a scenario like this? P.S. If this is off topic feel free to close it -- I think it's borderline and I'm of the opinion that it's better to ask and be closed than not ask at all ;)

  • debugging scaffolding contingent upon degbugging boolean (java)

    - by David
    Recently i've found myself writing a lot of methods with what i can only think to call debugging scaffolding. Here's an example: public static void printArray (String[] array, boolean bug) { for (int i = 0; i<array.lenght; i++) { if (bug) System.out.print (i) ; //this line is what i'm calling the debugging scaffolding i guess. System.out.println(array[i]) ; } } in this method if i set bug to true, wherever its being called from maybe by some kind of user imput, then i get the special debugging text to let me know what index the string being printed as at just in case i needed to know for the sake of my debugging (pretend a state of affairs exists where its helpful). All of my questions more or less boil down to the question: is this a good idea? but with a tad bit more objectivity: Is this an effective way to test my methods and debug them? i mean effective in terms of efficiency and not messing up my code. Is it acceptable to leave the if (bug) stuff ; code in place after i've got my method up and working? (if a definition of "acceptability" is needed to make this question objective then use "is not a matter of programing controversy such as ommiting brackets in an if(boolean) with only one line after it, though if you've got something better go ahead and use your definition i won't mind) Is there a more effective way to accomplish the gole of making debugging easier than what i'm doing? Anything you know i mean to ask but that i have forgotten too (as much information as makes sense is appreciated).

  • OO vs Simplicity when it comes to user interaction

    - by Oetzi
    Firstly, sorry if this question is rather vague but it's something I'd really like an answer to. As a project over summer while I have some downtime from Uni I am going to build a monopoly game. This question is more about the general idea of the problem however, rather than the specific task I'm trying to carry out. I decided to build this with a bottom up approach, creating just movement around a forty space board and then moving on to interaction with spaces. I realised that I was quite unsure of the best way of proceeding with this and I am torn between two design ideas: Giving every space its own object, all sub-classes of a Space object so the interaction can be defined by the space object itself. I could do this by implementing different land() methods for each type of space. Only giving the Properties and Utilities (as each property has unique features) objects and creating methods for dealing with the buying/renting etc in the main class of the program (or Board as I'm calling it). Spaces like go and super tax could be implemented by a small set of conditionals checking to see if player is on a special space. Option 1 is obviously the OO (and I feel the correct) way of doing things but I'd like to only have to handle user interaction from the programs main class. In other words, I don't want the space objects to be interacting with the player. Why? Errr. A lot of the coding I've done thus far has had this simplicity but I'm not sure if this is a pipe dream or not for larger projects. Should I really be handling user interaction in an entirely separate class? As you can see I am quite confused about this situation. Is there some way round this? And, does anyone have any advice on practical OO design that could help in general?

  • Language for non-programmers to start learning programming

    - by zarawesome
    A non-programmer friend will be starting the Computer Science college course in a few months. I'd like her to try her hand at some programming before she starts her studies (the course itself expects one to know C, but it's an horrible language to learn to program at). What language would be the best to do so? Related question: Best ways to teach a beginner to program?

  • Android Multiple Handlers Design Question

    - by Soumya Simanta
    This question is related to an existing question I asked. I though I'll ask a new question instead of replying back to the other question. Cannot "comment" on my previous question because of a word limit. Marc wrote - I've more than one Handlers in an Activity." Why? If you do not want a complicated handleMessage() method, then use post() (on Handler or View) to break the logic up into individual Runnables. Multiple Handlers makes me nervous. I'm new to Android. Is having multiple handlers in a single activity a bad design ? I'm new to Android. My question is - is having multiple handlers in a single activity a bad design ? Here is the sketch of my current implementation. I've a mapActivity that creates a data thread (a UDP socket that listens for data). My first handler is responsible for sending data from the data thread to the activity. On the map I've a bunch of "dynamic" markers that are refreshed frequently. Some of these markers are video markers i.e., if the user clicks a video marker, I add a ViewView that extends a android.opengl.GLSurfaceView to my map activity and display video on this new vide. I use my second handler to send information about the marker that the user tapped on ItemizedOverlay onTap(int index) method. The user can close the video view by tapping on the video view. I use my third handler for this. I would appreciate if people can tell me what's wrong with this approach and suggest better ways to implement this. Thanks.
