  • Card deck and sparse matrix interview questions

    - by MrDatabase
    I just had a technical phone screen w/ a start-up. Here's the technical questions I was asked ... and my answers. What do think of these answers? Feel free to post better answers :-) Question 1: how would you represent a standard 52 card deck in (basically any language)? How would you shuffle the deck? Answer: use an array containing a "Card" struct or class. Each instance of card has some unique identifier... either it's position in the array or a unique integer member variable in the range [0, 51]. Shuffle the cards by traversing the array once from index zero to index 51. Randomly swap ith card with "another card" (I didn't remember how this shuffle algorithm works exactly). Watch out for using the same probability for each card... that's a gotcha in this algorithm. I mentioned the algorithm is from Programming Pearls. Question 2: how to represent a large sparse matrix? the matrix can be very large... like 1000x1000... but only a relatively small number (~20) of the entries are non-zero. Answer: condense the array into a list of the non-zero entries. for a given entry (i,j) in the array... "map" (i,j) to a single integer k... then use k as a key into a dictionary or hashtable. For the 1000x1000 sparse array map (i,j) to k using something like f(i, j) = i + j * 1001. 1001 is just one plus the maximum of all i and j. I didn't recall exactly how this mapping worked... but the interviewer got the idea (I think). Are these good answers? I'm wondering because after I finished the second question the interviewer said the dreaded "well that's all the questions I have for now." Cheers!

  • Goal Tracking data seems to be inaccurate?

    - by Khuram Malik
    I setup some Goal Tracking about one week ago. I had multiple goals in one set. The goal itself was the "send" button being pressed on the callback form (i did that by pushing a pageview to Google Analytics everytime the send button is pressed) For each goal, i listed the first step as a required step. So for example, the ILR Page was step 1 and set as required and the goal was "/CallbackFormFilled" Looking at the stats a week later i'm getting some very inflated numbers especially when comparing them to my manually filled excel spreadsheet and i'm struggling to understand the cause of this behaviour. I'm unable to attach screenshots unfortunately since my StackExchange account for this site is brand new My own thoughts My own thoughts were that maybe its because i have setup multiple goals with the same end goal URL, but i thought that was a valid setup since i want to track multiple routes so to speak(?) I've disabled all other goals for now to confirm this, but im waiting for stats to come in as i write this. I also wonder if the contact form im using in Wordpress is causing a problem, but i've simply added one javascript line on the send button that pushes a pageview so not sure if that should cause an issue. Here is a link to setting up analytics on this contact form plugin in wordpress for reference: (see javascript action hook section) - http://ideasilo.wordpress.com/2009/05/31/contact-form-7-1-10/

  • Delete Data From Your Hardrive With DBAN

  • Brasero Burns Data, Not Time - or Piles of Discs

    <b>Linux Insider:</b> "There are a lot of CD/DVD burners for Linux out there, but Brasero stands out as a straightforward, easy-to-use, burner that has some nice extra features but won't make you relearn a lot of complex commands if you only use it occasionally. One nicety is the option to start a burn project and finish it much later, even if you're not using a rewritable disc."

  • How to import Evolution application data from home folder backup

    - by Wolter Hellmund
    I had many folders and filters and mail in general in Evolution on my previous Ubuntu install, which I thought would be available for me for I had backed up my home directory. I have copied now Evolution related folders to my new home directory, and Evolution is not showing either the folders I had or any of the filters. To be more precise, I have copied the mail folder to ~/.config/evolution/ but that hasn't changed anything, as I said.

  • Direct3d - Code structure

    - by marcg11
    I'm learning directx in a master's degree and they taught us to have a GraphicsLayer class which is the one connecting with the direct3d library. That way this class is completly independent from the other classes (my game classes), meaning changing the renderer to OpenGL wouldn't require much effort but only changing the graphicLayer. This classe has it's LoadAssets, Paint methods, but I have a question, they told us to load all the assets inside this class. This means all these methods will be in the loadAssets method: D3DXCreateTextureFromFileEx(g_pD3DDevice,"tiles.png",0,0,1,0,D3DFMT_UNKNOWN,D3DPOOL_DEFAULT,D3DX_FILTER_NONE,D3DX_FILTER_NONE,NULL,NULL,NULL,&texTiles); // And more resources to load //... texTiles as you see is a LPDIRECT3DTEXTURE9 instance which is declared in the graphicLayer.h. So my question is, how do you manage all the resources? Do I have to declare in the .h all my game textures even if I'm not using them? How would you load only those resources there are in a scene and draw them in a code-strucured way?

  • Migrate data from one server to another using rsync

    - by Leonid Shevtsov
    I'm moving from one VPS to another, and I figured that the simplest way to transfer data would be rsync. However, the data is owned by a user, www-data, which doesn't have ssh privileges, and I'd like it to be owned by the same (named) user on the target machine. Obviously I need all file permissions preserved. I have SSH access via another user with sudo privileges on both machines. Is this possible to do this with rsync?

  • Calculate minimum ext3 partition size for certain amount of data

    - by Daniel Beck
    These following ext3 partitions contain identical data. As we can see, the larger the partition size, the more space is required for the same files: Filesystem 1K-blocks Used Available Use% Mounted on /dev/loop11 3965777 561064 3199964 15% [...] /dev/loop19 573029 543843 29186 95% [...] Filesystem Size Used Avail Use% Mounted on /dev/loop11 3.8G 548M 3.1G 15% [...] /dev/loop19 560M 532M 29M 95% [...] Filesystem Inodes IUsed IFree IUse% Mounted on /dev/loop11 1024000 1656 1022344 1% [...] /dev/loop19 1024000 1656 1022344 1% [...] I start with a partition of fixed size that possibly wasted a lot of space and I want to create a partition that is able to hold that data but with (almost) minimal size. How can I reliably calculate that minimal partition size needed for storing a certain amount of data? The amount of data changes over time, and I need to automate these calculations.

  • How do you think the industry for programmers is right now? [closed]

    - by Mercfh
    I recall 5-6 years ago there was quite a slump in jobs, but 5-6 years ago I was just starting college so I was oblivious to what was going on, however I had heard about it at many places. And obviously there's the recession that we are in now (although I've been told things have been getting better). So what's the job outlook for programmers right "now"? Good? Bad? Average? When I was looking for a job 2 months ago I "saw" quite a bit of job openings near my city, but that could've just been me living in a lucky "growing" area.

  • What is the usage of Spaly Trees in the real world?

    - by Meena
    I decided to learn about Balance search trees, so I picked 2-3-4 and splay trees. I'm wondering what are the examples of splay trees usage in the real world? In this Cornell: http://www.cs.cornell.edu/courses/cs3110/2009fa/recitations/rec-splay.html I read that splay trees are 'A good example is a network router'. But from rest of the explanation seams like network routers use hash tables and not splay trees since the lookup time is constant instead of O(log n). thanks!

  • How can I clear *old* browsing data from Google Chrome Linux, while keeping more recent data?

    - by Norman Ramsey
    I can find plenty of information on how to clear Google Chrome's recent browsing data, in various periods, as well as clearing all browsing data. But I want to clear old browsing data—say for a start, anything over two months old. (I'm trying to save space on a crowded laptop.) Does anyone know any principled way to do this, or shall I just dive into ~/.config/google, start removing likely-looking files, and hope for the best. I run Google Chrome on Debian Linux.

  • Need Help Unable to Mount Location

    - by Don't ASk Ubun
    I am not able to start Windows and am using a DVD copy of Ubuntu to start up. I see my 750 GB Hard Disk, but if I click it i get this error: Error mounting: mount exited with exit code 13: ntfs_attr_pread_i: ntfs_pread failed: Input/output error Failed to read NTFS $Bitmap: Input/output error NTFS is either inconsistent, or there is a hardware fault, or it's a SoftRAID/FakeRAID hardware. In the first case run chkdsk /f on Windows then reboot into Windows twice. The usage of the /f parameter is very important! If the device is a SoftRAID/FakeRAID then first activate it and mount a different device under the /dev/mapper/ directory, (e.g. /dev/mapper/nvidia_eahaabcc1). Please see the 'dmraid' documentation for more details. After googling for a while I think I need to do sudo apt-get install ntfsprogs but when I try that: E: Package 'ntfsprogs' has no installation candidate My problem is a lot like this thread

  • Excel: making line charts so the line goes through all data points

    - by Mike
    Hi I've got data based on over 50+ years for various products. Unfortunately not all products have data for each year. I've created a line chart to show the movement (quantity sold) of these products over the years. It works well, except where the data points are too far apart i.e. 1965 and then 1975. For some reason there is no line. It's not perfect data because of the missing years, but I can live with that, I just want to see the trend, and not just sporadic dots; squares or crosses. Any help or links greatly appreciated. Mike

  • Attaining credit card data

    - by Adam
    I've read the many posts on this site that say we are not allowed to store cc numbers if we are not pci-compliant. But, I'm wondering if it is possible to send a CC number through a form to an email address? Would that be still infringing on the standards? The reason I ask is that a local business owner wants to retrieve a number through a form on his website, so he can manually enter the cc info on his end. I'm assuming the only way to properly get a credit card number is to setup a merchant account? What's the best way to get a cc number without calling the actual customer? I'm thinking email is a bad idea as well.

  • Storing application preferences and data

    - by Rudi Strydom
    I am looking at creating some Ubuntu applications, but finding good resoures are hard. I am using the quickly toolkit, but would really like some more insight. How does one normally store application preferences and settings in Linux / Ubuntu. Is it as simple as creating a XML file and saving the information and then reading from said file on application bootstrap? If someone can point me in a direction it would be greatly appreciated.
