  • An intern interview with Microsoft [on hold]

    - by Wobbles
    I'm currently in my second year(Computer Science and Mathematics). In two days I have an interview on campus with Microsoft. I'm a bit nervous, because this will be my first in person interview. I have done reviewed basic things like linked list and binary trees. I am not really sure what kinds of questions I'll be asked. Has anyone been to such interview? If so what's it like? What kinds of questions will I be asked? Any help/suggestions will be much appreciated! Also can someone provide me with a list of things I ought to know for the interview?

  • busybox initramfs prompt while attempting to install from live cd on 2nd hdd

    - by da92n
    busybox initramfs prompt while attempting to install from live cd on 2nd hdd I've created a partition in ext3 on my second hdd to intall linux however when i come to boot the CD i get directed to a busybox prompt with no other choice than help. Other topics i've read on the subject where bound to the idea ubuntu has been already installed, and that the partition needs to be just indicated or else... But since i've no ubuntu installed, neither have i any partition that ubuntu should consider like that... How can i go through that?

  • Checking whether the user input is a str in Python [migrated]

    - by Sahil Babbar
    I checked various questions on Stack Overflow but one thing every logic lacks. Let me demonstrate using Python: while True: user_input = raw_input() if type(user_input) == str: print 'ERROR' else: print 'BINGO' Also, we cannot use input() in place of raw_input() as it gives the error:Traceback (most recent call last): File ".\test.py", line 3, in <module> user_input = int(input()) File "<string>", line 1, in <module> NameError: name 'asdf' is not defined The problem here is that raw_input converts the user input into string so it always prints 'ERROR' and if I change the second line to user_input = int(raw_input) then, it gives an error: Traceback (most recent call last): File ".\test.py", line 3, in <module> user_input = int(raw_input()) ValueError: invalid literal for int() with base 10: 'asdf' I tried this with try and except but it shall work fine to check integer but not a string. I feel that this question may be marked as a duplicate but I think that this query is important, if logically taken.

  • Phantom activity on MySQL

    - by LoveMeSomeCode
    This is probably just my total lack of MySQL expertise, but is it typical to see lots of phantom activity on a MySQL instance via phpMyAdmin? I have a shared hosting plan through Lithium, and when I log in through the phpMyAdmin console and click on the 'Status' tab, it's showing crazy high numbers for queries. Within an hour of activating my account I had 1 million queries. At first I thought this was them setting things up, but the number is climbing constantly, averaging 170/second. I've got a support ticket in with Lithium, but I thought I'd ask here if this were a MySQL/shared host thing, because I had the same thing happen with a shared hosting plan through Joyent.

    I need to build a highload multithreaded web application in ASP.NET MVC3 or MVC4, My question is how to design an architecture of an application?

  • Quick path jumping

    - by Sebastian P.
    I was just at a lecture, where I noticed the lecturer using a command (probably aliased) to jump to a specific folder. Example: ~/code$ j sciproj ~/projects/sciproj2011/$ This looked quite slick, so I started wondering: Is this a standard utility, and if so, what is the name? I have two theories as to how it works: It can both create, delete and jump to aliases directly from the command-line in the style of the example, without having to set up aliases in a configuration file or script or whatnot manually. It searches the home directory for a folder matching the name and jumps to it. The second option seems a bit slow, however, so the first would be preferred.

  • Moving OVD from Test to Production

    - by mark.wilcox
    Customer asked support "How to move a test OVD server to production". There is a couple of ways to do this. One way is to clone the environment: http://download.oracle.com/docs/cd/E15523_01/core.1111/e10105/testprod.htm#CH... Another way - which is particularly useful if you want to push configuration from a parent OVD server to children in a cluster: http://download.oracle.com/docs/cd/E14571_01/oid.1111/e10046/basic_server_set... Note if you use the second option and you have any data in a Local Store Adapter - you may also need to use the oidcmprec tool to synchronize that data: http://download.oracle.com/docs/cd/E14571_01/oid.1111/e10029/replic_mng_mon.h...

    - by hhh
    I need a secure git -repo host, either by third-party or by myself. I am not sure how so outlining some ideas. Please, answer how you manage git -repos securely -- do you use some service or do you use only your 'legs' -approach? Afaik Bitbucket.org and Github.com are missing Gmail -style second-verification. Now I need this kind of login-system with password and mobile-phone to access the administration things in the git -hosting or ability to disable this kind of access without private -key.

  • Problems about responsiveness and keyboard/mousepad not working

    - by ChrisTheNoob
    So I installed Ubuntu 12.04, I'm very new at this and want to get into the world of Linux but have run into nothing but problems. I have an Acer Aspire 5553g. First off, my keyboard won't work. Second, my computer has more than enough of everything to run Ubuntu smoothly, but everything runs extremely slow. (You move the mouse and it gets there a few seconds later) It's to the point where I can't even use it and I really want to. I'm tired of Microsoft stuff and I've been looking at learning how to use Linux based operating systems for a while. Please send me some help to fix these issues and maybe some tips to help get me started. Thanks in advance chris

    - by Nicky Bailuc
    10 latest updates and drivers and I need to run a game called unreal tournament, but in terminal it requires 2 commands The first one is to mount into the folder: cd /usr/local/games/ut2004/ and then the second one is to open the actual game: sudo aoss ./ut2004 In one shortcut i can only fit 1 command but both don't fit in is there any way i can turn these 2 commands into one? Perhaps turni9ng on the desktop shortcut already mounted into the folder? Any help would be really appreciated because im getting kinda sick of using the terminal to run it every time.

  • When should one use "out" parameters?

    - by qegal
    In Objective-C, there are several methods like initWithContentsOfFile:encoding:error: where one passes in a reference to an NSError object for the error: parameter. In this example, the value of the NSError object passed in can change based on what goes on at runtime when the method is being called and whether the body of the method was executed in a certain way successfully. In a way I think of this NSError object as sort of like a second return value from the method, and only differs from an object anObject in the statement return anObject; in that when this statement is called, execution leaves the method. So my question is, not only in the context of error handling in Objective-C, but in general, when should one use an "out" parameter in place of returning said value in a return statement?

  • What is the worst programmer habit?

    - by 0x4a6f4672
    Many people get into programming because programming is fun. At least in the beginning. After some time doing it professionally, programming is no longer fun, often just hard work. Sometimes we develop bad habits along the way to make it fun again. Some bad habits of programmers are well known, for example the "I fix that in a second" habit, the "reinvent the wheel" practice or the "all code except mine is crap" attitude (which often leads to "I will re-write the entire program from scratch" syndrome). There are things which a programmer should never do. What is the worst programmer habit?

  • How to suppress "Card not present / present" spam in syslog?

    - by vava
    I'm getting a lot of Dec 27 08:35:49 htpc kernel: [ 1552.153797] pciehp 0000:00:1c.5:pcie04: Card not present on Slot(0-2) Dec 27 08:35:49 htpc kernel: [ 1552.157744] pciehp 0000:00:1c.5:pcie04: Card present on Slot(0-2) messages in my syslog, about 10 every second. That just makes syslog unusable, can I somehow get rid of them? I don't know and don't really care about the reason of those messages being there, partly because my motherboard doesn't have pcie slots on it and partly because everything I care about works perfectly. That might be a WiFi chip I disabled in bios but hey, I don't want wifi to be powered on, I'm not using it. So can I just suppress those messages?

  • memory and time intensive php task

    - by Goddard
    Sorry if this question has been asked before, but I couldn't find anything usable. I'm working on a project for a client and currently I have to loop through the users table which is about 3000 records and still growing. I have to do some calculations on a nightly basis which I am going to be using cron/php. The calculations script uses about 3.5mb of memory and takes about 1 second to run. When loading individual users my current php setup handles this fine, but if I try and loop through the user list my php script execution time runs out. I've read after doing some searching that I can make the page reload itself after each user calculation and just keep my previous place in the loop and this sounds like a good idea, but I wanted to hear some opinions from others that have handled similar situations and how you handled these types of tasks. Thanks.

  • Learning C++ but wanting to develop iOS Apps

    - by DiscreteGenius
    I'm a computer engineering student and taking my second programming class. I'm learning C++ using "C++ Primer Plus" 5th edition by Prata. I want to develop for iOS. I understand the main language for Xcode is Objective-C. Am I hurting myself by learning C++ before any other language (notably before my desired lang Objective-C)? There's got to be a reason the university requires C++ to learn as a basis language. Please offer any helpful guidance or how I should go about this. Thanks//

  • Why does Unity in 2d mode employ scaling and the default othographic size the way it does?

    - by Neophyte
    I previously used SFML, XNA, Monogame, etc to create 2d games, where if I display a 100px sprite on the screen, it will take up 100px. If I use 128px tiles to create a background, the first tile will be at (0,0) while the second will be at (129,0). Unity on the other hand, has its own odd unit system, scaling on all transforms, pixel-to-units, othographic size, etc etc. So my question is two-fold, namely: Why does Unity have this system by default for 2d? Is it for mobile dev? Is there a big benefit I'm not seeing? How can I setup my environment, so that if I have a 128x128 sprite in Photoshop, it displays as a 128x128 sprite in Unity when I run my game? Note that I am targeting desktop exclusively.

  • Ruby - when to use instance variables vs parameters between methods?

    - by Michael Durrant
    I'm writing several methods that call other methods. To pass the information I have a couple of choices: Pass the information as parameters Set instance variables so that other methods can access them When should I choose one option over the other? It seems that the first option is good as it is very specific about what is being passed. the downside seems to be that a lot of values are being passed around. The second method doesn't require passing all the values around but seems to lead to a lot of magic where methods set instance variables 'somewhere' Should I always be very explicit about gets passed to other methods in the class? Are there exceptions so this?

  • Confusion about Rotation matrices from Euler Angles

    - by xEnOn
    I am trying to learn more about Euler Angles so as to help myself in understanding how I can control my camera better in the game. I came across the following formula that converts Euler Angles to rotation matrices: In the equation, I could see that the first matrix from the left is the rotation matrix about x-axis, the second is about y-axis and the third is about z-axis. From my understanding about ordinary matrix transformations, the later transformation is always applied to the right hand side. And if I'm right about this, then the above equation should have a rotation order starting from rotating about z-axis, y-axis, then finally x-axis. But, from the symbols it seems that the rotation order start rotating about x-axis, then y-axis, then finally z-axis. What should the actual order of the rotation be? Also, I am confuse about if the input vector, in this case, would be a row vector on the left, or a column vector on the right?

  • Is this a bad time to be majoring in computer science?

    - by ATMathew
    There has been a lot of media attention paid in recent months and years to the increase in CS majors and the possibility of a second tech bubble. Some news reports have suggested that as more people enter CS, the market could be flooded with CS professionals and jobs could be increasingly difficult to find. Is this a bad time to be majoring in computer science? Edit: I'm a non-trad student who allready has a Bachelor's degree in economics and will be pursuing a CS degree starting this upcoming summer semester at the Univ of Kansas. I've been programming for about two/three years and just need a more formal education to fill the holes in my head. I have an interest in CS, it's just that I am worries about the prospects for the future.

  • ubuntu 12.10 graphic does not works correctly

    - by Amin
    I have installed Ubuntu 12.10 but my graphic does not works correctly. I used this command to installation: sudo apt-get install fglrx fglrx-amdcccle fglrx-dev But after the restarting my system, the side panel and upper one does not appear any more! I guessed it maybe that I used some incompatible packages so I removed the graphic card driver by this command: sudo apt-get purge fglrx fglrx-amdcccle fglrx-dev and tried it from graphical way from system setting > Software Sources > Aditional drivers and choosed the second option then applied change. But the resault waas such as before way!! I belive it is because of the Ubuntu does not know my graphic card. I am using VAIO VPCEA2TGX (N/A) and my graphic cart version is Mobility Radeon HD 5400 Series if it is matter. So now what is the exact problem and what I have to solve this?

  • From the Classroom to the Boardroom

    - by Maria Sandu
    Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 Pens and Paper...these are the only things being a student and being a graduate / professional have in common. Walking in to the offices of Oracle South Africa as a graduate the first thing you notice is how polished and sleek all the people who work here look. 80% of the ladies wear sky-scraper heels and walk with the greatest grace. This was the first of many rude awakenings to remind me that I am no longer a student but a graduate. My first struggle was having to wake up at wee hours of the morning to prepare for work. As a student going to class was almost an optional thing, if you missed a morning class you could always attend an evening class to make up for it or simply attend with another group. But in the workplace, you HAVE to show up every single morning at the same time, with no option of coming in when it suits you and there is definitely no coming in with the evening class/shift. As a student, the earliest hour I ever woke up was 7:00am, anything earlier than that was considered inhumane torture. My reason for waking up every morning as a student was “you have a degree to go get” but as a graduate having to go to work I have to say to myself “here’s to a new day of learning and growing”. My second struggle has come in having to change my beloved wardrobe. Everyone who knows me knows how passionate I am about fashion and shopping. For me Shopping is a BASIC HUMAN RIGHT, that should not be messed with. Therefore it was with great sadness that I swopped my rippled skinny jeans for pin-striped formal pants, my long chandelier earrings for simple studs, my flat shoes for heels, my sheer blouses for crisp white shirts, even my beloved wild hair had to make way for a simple ponytail. Our looks as ladies also came under great scrutiny, we had to acquaint ourselves with some serious grooming tools: the mascara, blush, lip-gloss, blush, a touch of lipstick and a manicure set. Language was a struggle of its own as well. Being a student you learn to relate to your peers in a informal way. In the workplace you have to address everyone with the same respect, including your peers. Words like “Hey buddy” had to make way for “good morning friend”. The month long winter school holiday was one of the things I looked forward to as a student. This was a time where we got to be at home and avoid the coldest month of the year, July. It was the most amazing thing ever, just sleeping and snuggling up to all sorts of warm things but sadly it is now a thing of the past. It is currently winter in South Africa and going to work has become the most unfashionable thing with all the jackets, boots, scarves and gloves. But summer is coming and I will miss those holidays too. As a student the school holidays were like a gift for us to catch a break and not think for a while which was why it was imaginable how someone would go on for the entire year without a break, with only the promise of a mere 21 days annual leave!! Right now I am sure we are all looking forward to taking that annual leave when the time is right. The worst rude awakening I must say, has to be presenting in front of clients and managers. As a student you have the same class mates for almost four years therefore presenting in front of them becomes the norm over the years and your lecturer will always go gently on you. What they don’t tell you at University is that in the real world, time is money and clients pay money to see you present therefore there is no room for error. Clients are not there to give you a score and boost your ego, they expect nothing less than 100% and they will let you know without a second thought. For a graduate this can feel like you are being fed to the sharks, you either get eaten or you swim for your life. At the end of the day, it is all an experience that is meant to groom us into better professional and make us a part of the Red Team. All the sacrifices are worth it and they lead us to being better and more polished professionals.

  • Ubuntu Freezes w/ Proxy

    - by jrc03c
    Ubuntu 11.04 freezes completely after a little while when using a proxy. It's fine when it's got a direct Internet connection, but it completely grinds to a halt after about 10 or 15 minutes of traffic through a proxy. Any ideas? UPDATE: Here's some more information. I have a second-generation MacBook, which has both OSX 10.6.8 (Snow Leopard) and Ubuntu 11.04 (Natty Narwhal) installed on it. When running through a proxy, Snow Leopard works fine, but Ubuntu freezes frequently. Any suggestions at all? Or, rather, what other kinds of information do you need?
