• What is the biggest weakness of students graduating with degrees in Computer Science?

  - by akobre01

  This question is directed more toward employers and graduate student advisors/professors but all opinions are welcome. What do you find is a common weakness of new hires and/or new grad students? Is it entirely variable dependent on the student and his or her university? Is there a particular skill or skillset that you wish new hires/researchers had expertise in and how can we remedey this deficiency? I realize that this question is general and really encapsulates two questions, one more about the weaknesses of new software engineers and one about the weaknesses of new researchers. However, both types of people tend to come from similar courses of study so I'm wondering if there is any overlap. Note: I am not a professor but I'm interested in how best to revise the undergraduate curriculum in CS.

• Running WordPress on Windows Server

  A few days ago, I saw someone posted on Twitter a question about running WordPress on Windows Server. Since I had done this for a few sites, I responded with my thoughts and tips. Another suggested that I post those here, and so here I go. WordPress is a blogging/content-management platform that has been around for a while. It has been gaining more in popularity for general purpose content sites over the past year Id say, but is primarily seen as a blogging platform by most. Even though I use Subtext...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• What are some methods for pulling information and interacting with flash games?

  - by Xploit

  In general, how should I approach interacting with a flash game pragmatically? The flash game is online and I would like to be able to pull information from the game, make computations, and send the appropriate keystrokes back to the flash game? I'm having difficult deciding how to begin. Any specific libraries or languages that you feel would be best for accomplishing this task? I would like it to be as fast as possible. Are there ways of doing this without taking screen shots and simulating keyboard presses?

• Can you be a programmer and Business manager at the same time?

  - by the_knight5000

  Hello all, I think I'm struggled in some situation! We are a new start-up with 5 employees (2 Programmers). I'm the Technical Manager and that was so fine! Now I can see the fingers point to me to take the control of everything, as I've the big vision of what our organization do and play the role of CEO or General Manager! I want to, but I've no idea if it would be risky to our organization to make such a decision? How would managerial interrupts affect the technical productivity? Any tips or previous experience about such situation would help :) Thanks in advance!

• Collision: Vector class (java)

  - by user8363

  When handling collision detection / response and you need a Vector class, do you need to create that class yourself or is there a java class you can use? A vector class should have methods like: subtract(Vector v), normalize(), dotProduct(Vector v), ... At the moment it seems logical to use classes like java.awt.Rectangle and java.awt.Polygon to calculate collisions. Would I be right to use these classes for this purpose? My question is not about how to implement collision detection, I know how that works. However I'm wondering what would be a correct and clean way to implement it in java since I'm fairly new to the language and to application development in general.

• What are some concise and comprehensive introductory guide to unit testing for a self-taught programmer [closed]

  - by Superbest

  I don't have much formal training in programming and I have learned most things by looking up solutions on the internet to practical problems I have. There are some areas which I think would be valuable to learn, but which ended up both being difficult to learn and easy to avoid learning for a self-taught programmer. Unit testing is one of them. Specifically, I am interested in tests in and for C#/.NET applications using Microsoft.VisualStudio.TestTools in Visual Studio 2010 and/or 2012, but I really want a good introduction to the principles so language and IDE shouldn't matter much. At this time I'm interested in relatively trivial tests for small or medium sized programs (development time of weeks or months and mostly just myself developing). I don't necessarily intend to do test-driven development (I am aware that some say unit testing alone is supposed to be for developing features in TDD, and not an assurance that there are no bugs in the software, but unit testing is often the only kind of testing for which I have resources). I have found this tutorial which I feel gave me a decent idea of what unit tests and TDD looks like, but in trying to apply these ideas to my own projects, I often get confused by questions I can't answer and don't know how to answer, such as: What parts of my application and what sorts of things aren't necessarily worth testing? How fine grained should my tests be? Should they test every method and property separately, or work with a larger scope? What is a good naming convention for test methods? (since apparently the name of the method is the only way I will be able to tell from a glance at the test results table what works in my program and what doesn't) Is it bad to have many asserts in one test method? Since apparently VS2012 reports only that "an Assert.IsTrue failed within method MyTestMethod", and if MyTestMethod has 10 Assert.IsTrue statements, it will be irritating to figure out why a test is failing. If a lot of the functionality deals with writing and reading data to/from the disk in a not-exactly trivial fashion, how do I test that? If I provide a bunch of files as input by placing them in the program's directory, do I have to copy those files to the test project's bin/Debug folder now? If my program works with a large body of data and execution takes minutes or more, should my tests have it do the whole use all of the real data, a subset of it, or simulated data? If latter, how do I decide on the subset or how to simulate? Closely related to the previous point, if a class is such that its main operation happens in a state that is arrived to by the program after some involved operations (say, a class makes calculations on data derived from a few thousands of lines of code analyzing some raw data) how do I test just that class without inevitably ending up testing that class and all the other code that brings it to that state along with it? In general, what kind of approach should I use for test initialization? (hopefully that is the correct term, I mean preparing classes for testing by filling them in with appropriate data) How do I deal with private members? Do I just suck it up and assume that "not public = shouldn't be tested"? I have seen people suggest using private accessors and reflection, but these feel like clumsy and unsuited for regular use. Are these even good ideas? Is there anything like design patterns concerning testing specifically? I guess the main themes in what I'd like to learn more about are, (1) what are the overarching principles that should be followed (or at least considered) in every testing effort and (2) what are popular rules of thumb for writing tests. For example, at one point I recall hearing from someone that if a method is longer than 200 lines, it should be refactored - not a universally correct rule, but it has been quite helpful since I'd otherwise happily put hundreds of lines in single methods and then wonder why my code is so hard to read. Similarly I've found ReSharpers suggestions on member naming style and other things to be quite helpful in keeping my codebases sane. I see many resources both online and in print that talk about testing in the context of large applications (years of work, 10s of people or more). However, because I've never worked on such large projects, this context is very unfamiliar to me and makes the material difficult to follow and relate to my real world problems. Speaking of software development in general, advice given with the assumptions of large projects isn't always straightforward to apply to my own, smaller endeavors. Summary So my question is: What are some resources to learn about unit testing, for a hobbyist, self-taught programmer without much formal training? Ideally, I'm looking for a short and simple "bible of unit testing" which I can commit to memory, and then apply systematically by repeatedly asking myself "is this test following the bible of testing closely enough?" and then amending discrepancies if it doesn't.

• Data structures for storing finger/stylus movements in drawing application?

  - by mattja?øb

  I have a general question about creating a drawing application, the language could be C++ or ObjectiveC with OpenGL. I would like to hear what are the best methods and practices for storing strokes data. Think of the many iPad apps that allow you to draw with your finger (or a stylus) or any other similar function on a desktop app. To summarize, the data structure must: be highly responsive to the movement store precise values (close in space / time) usable for rendering the strokes with complex textures (textures based on the dynamic of the stroke etc) exportable to a text file for saving/loading

• How to structure an application which reads UPC barcodes

  - by tugberk

  I have no previous experience on creating a project for a seller which will use barcode reader. I am trying to put together a small project but I cannot figure out how the pieces should glue together. I will create a sample with Motorola Scanner SDK to read barcodes and from that point, I have couple of questions: How UPC barcodes work in general? AFAIK, a barcode stores the manufacturer and product info but no price data. Should I store price information inside a database which corresponds to barcode data? I would really appreciate if you can guide me here.

• Want to use h264 in my commercial program. What steps should i take?

  - by Jason123

  Want to use h264 in my commercial program. What steps should I take? Here is what I see that needs to be done. I need to buy a license from VideoLan (x264licensing.com) to use the library to encode video into h264 format and I need to buy a license from the MpegLAGroup to use the h264 video encoding in general in my commercial product. Am I right in thinking that? How much do these cost? I don't see selling much since my target is very niche (video game screen capturing).

• IIS and content caching

  - by JayC

  I'm a web developer and administer of a Windows 2008R2 Could Instance with IIS 7. I recently made an update to our website, but when I revisited the website, the website was being viewed with old stylings. I did a refresh (shift + reload button in Firefox) and of course the website displayed as it should. I didn't worry about it, until my client had the same issue in Safari. So, my question, in general, is, how do I prevent this from happening again, and yet still afford some caching of our site? I noticed we did not have content expiration set up on our webserver sites, so I've set that up, but did I really need to? I've also looked at Etags, and, honestly, it's hard for me to know whether or not I should use them or not. One comment I read somewhere there isn't really any issue with Etags scenarios in IIS (even in webfarms)... but, I dunno. Anybody have any suggestions, links, info? Thanks.

• Distributed cache and improvement

  - by philipl

  Have this question from interview: Web Service function given x static HashMap map (singleton created) if (!map.containsKey(x)) { perform some function to retrieve result y map.put(x, y); } return y; The interviewer asked general question such as what is wrong with this distributed cache implementation. Then asked how to improve on it, due to distributed servers will have different cached key pairs in the map. There are simple mistakes to be pointed out about synchronization and key object, but what really startled me was that this guy thinks that moving to database implementation solves the problem that different servers will have different map content, i.e., the situation when value x is not on server A but on server B, therefore redundant data has to be retrieved in server A. Does his thinking make any sense? (As I understand this is the basic cons for distributed cache against database model, seems he does not understand it at all) What is the typical solution for the cache growth issue (weak reference?) and sync issue (do not know which server has the key already cached - use load balancing)? Thanks

• Software patents [closed]

  - by user71622

  not exactly sure where I should post this but I have a question about filing for software patents. If I have an idea for a UI feature, how do I go about patenting that feature. I don't have any code written and I'm afraid my coding skills aren't up to snuff in order to code the thing I imagined but aside from that, can anyone give me any general guidance and info? I've gone through the CIPO site (Canada's patent office) but haven't come away with enough information on what I'm trying to patent but what I have understood is that I have to very thorough in describing what I'm trying to patent and showing that it could work. If anyone has gone through the process of patenting software, can you tell me about your experience? I would like to hear about US and Canadian experiences Thank you!

• Domain held at one registry, need to redirect to subdomain on my own hosting provider

  - by Glinkot

  Hi, There are lots of questions around this general area, but I haven't seen one that exactly mirrors what I'd like to know. It's per the title really. My understanding (and what I'm told by my host) is the easiest thing is just to get the transfer key and bring the DNS across to my own hosting provider. Also I'm told by my host this doesn't affect the client's ownership of the domain itself. Basically, I have a subdomain setup with the site (this has the same IP address as the top level domain). So presumably just giving the other registrar that IP address will only refer it only to the TLD rather than the subdomain. What's the easiest way to achieve this? It's an asp.net site, I don't have a hosted directory on the client's account where I can code a redirect. Thanks all Mark

• Are Web Safe Colors Still Relevant?

  - by VxJasonxV

  I still remember one of my high school teachers lecturing us about the "web safe colors". A set of 216-256 colors that you should confine your designs to use, and nothing else besides them. Last I knew, Photoshop still has the "web safe" yield icon[1] on it's color picker. Are web safe colors still a concern? Outside of the obvious application (accessibility, legacy software versions, etc.), how much consideration should I give to limiting my color choice for my general audience? [1] Or was it the cube? I never remember.

  I did a clean install of 14.04 on a crucial M4 64gb ssd. The system boots in less than 30 seconds now! but.. when I leave it idle for a few hours and log back in nothing works .. if I do a simple command like df ..I get a dbus error message. I also have a toshiba sata disk mounted for general storage since the ssd is so small .. nothing appears to be damaged when I reboot but it is extremely annoying .. any ideas on how to correct this will be appreciated.

• Managing large downloadable content on mobile devices

  - by larromba

  This is a general question of how to best manage large downloadable content on mobile devices. Lets consider a situation whereby a mobile app needs to download a number of very large content items, like HD videos, that are over 500MB but under 2GB. Now, lets assume this content delivery system should be scalable. Would it be a fair assumption that: A reputable cloud service would be needed - if so, what is a reliable and cost effective cloud service for mobile devices based on anyone's experience? Large content downloads should only be attempted over a wifi connection, so the end user doesn't incur large costs, e.g. when travelling. Downloads should carry on in the background if possible, as the user won't want to wait in an app for long periods. If the downloads don't finish, or the OS quits the app, all downloads should carry on when the app is next activated? Are there any other pitfalls anyone may have experienced when managing large content on mobile devices? Thanks.

• Should Git be used for documentation and project management? Should the code be in a separate repository?

  - by EmpireJones

  I'm starting up a Git repository for a group project. Does it make sense to store documents in the same Git repository as code - it seems like this conflicts with the nature of the git revision flow. Here is a summary of my question(s): Is the Git revisioning style going to be confusing if both code and documents are checked into the same repository? Experiences with this? Is Git a good fit for documentation revision control? I am NOT asking if a Revision Control System in general should or shouldn't be used for documentation - it should. Thanks for the feedback so far!

• Is there an effective way to test XSL transforms/BizTalk maps?

  - by nlawalker

  Creating repeatable tests for BizTalk maps is frustrating. I can't find a way to handle testing them like I'd do unit testing, because I can't find ways to break them into logical chunks. They tend to be one big monolithic unit, and any change has the potential to ripple through the map and break a lot of unit tests. Even if I could break it up, creating XML test inputs is painful and error prone. Is there any effective way of testing these? I'd settle for recommendations for testing XSL transforms in general, but I specifically mention BizTalk maps primarily for the reason that when using the mapper, there really isn't any way to break your XSLT into templates (which I'd imagine you could use to break up your logic into testable chunks, but I've honestly never gotten that far with XSLT).

• Missed question in technical phone interview and the follow up letter

  - by Jacob

  I may have just bombed a C++ technical phone interview. The interviewer asked mostly about data structures and I was able to go into detail about each of the data structures he asked about. Score one for me I'm thinking. Wrong. Then he asks to join me on a collaboration website where he can see what I am typing. This was the same process as interview #1 which went well, not perfect, but well. So the question was: How do you reverse a linked list? he gave a function prototype similar to Node *reverse(Node *head) I struggled with this for about 10-15 minutes until the hour was up. I was able to get the general idea across but was not able to reverse the link list. My question is that after remembering the answer post interview do I mention this in the thank you letter, if I even should write one?

• What is the benefit of the "download will begin shortly" page?

  - by Fammy

  I've noticed many websites that host files for downloads have an interstitial page between the download link/button and the actual start of the download. Terminology on the page may include "Your download will begin shortly. If it does not, try this direct link". What is the purpose of this page? It seems to draw away from the general experience of downloading a file. Is this beneficial for bookmarking? Less experienced users? Analytics?

• Separating merged array of arithmetic and geometric series [closed]

  - by user1814037

  Possible Duplicate: Separating merged array of arithmetic and geometric series My friend asked me an interseting question. Given an array of positive integers in increasing order. Seperate them in two series, an arithmetic sequence and geometric sequence. The given array is such that a solution do exist. The union of numbers of the two sequence must be the given array. Both series can have common elements i.e. series need not to be disjoint. The ratio of the geometric series can be fractional. Example: Given series : 2,4,6,8,10,12,25 AP: 2,4,6,8,10,12 GP: 4,10,25 I tried taking few examples but could not reach a general way. Even tried some graph implementation by introducing edges if they follow a particular sequence but could not reach solution.
