  • Question about whether I should pursue minors or work towards a masters [closed]

    - by user75493
    I'm a sophomore about to go into my Spring semester in a few weeks and I am trying to decide some major things that will affect the next few years of my life and was looking for some guidance/advice. I'm currently working towards a Bachelors in Computer Science and my question was whether I should minor in Corporate Strategy and Math or just work towards a Masters in Computer Science? I was wondering if employers are more looking for Masters degrees in Computer Science or if those minors could be beneficial to me. Some things that may affect responses: I already have all my other requirements filled for graduating except my Computer Science classes, I've already had an internship this past summer and am already hearing back from several companies about internships for this upcoming summer. Thanks in advance! - Alex

  • A question on choosing the next programming language between C/C++ and other languages

    - by SidCool
    I am a java developer (web app and standalone applications) who knows JavaScript, HTML, CSS and has mostly worked on Web applications. I have no knowledge of C/C++ or any other lower level languages. I feel like I should strengthen my CS basics by learning a fundamental language. Should it be C or C++? I am also inclined to learn Objective-C. Does it need basics of C or C++? Or should I go for new languages like Python, Google's Go etc. I know this is a cliche question asked very frequently, but I can use some help here.

  • General usage question of vbo

    - by CSharpie
    Firstofall, I am sorry if my question is to broad. I am developing a tile based game and switched from those gl.Begin calls to using VBOs. This is kind of working allready, I managed to render a hexagonal polygon with a simple shader applied. What I am not sure is, how to implement the "whole" tile concept. Concrete the questions are: - Is it better to create 1 VBO for a single tile and render it n-Times in every different position, or render one huge VBO that represents the whole "world" - Depending on the answer above, what is the best way to draw a "linegrid". Overlay with the same vbo using the respecting polygon.mode , or is there a way to let the shader to this? - How would frustum-culling or mousepicking work then, do i need to keep the VBO-data in memory?

  • Question about main(String[] args) [migrated]

    - by Andrew0085
    I'm new to programming, and I'm using java. Here's a program I wrote: class HelloApp { static String hi; public static void main(String[] args) { int length = args.length; if (length > 0) { hi = args[0]; sayHi(); } } static void sayHi() { if (hi == "hello") { System.out.println("Hello!"); } } } My question is: Why doesn't inputting "java HelloApp hello" make "Hello!" appear on the next line?

  • iPhone TableView alternative options for Check Mark Accessory

    - by jimsis
    I'm looking for the best approach to this problem. In my tableview I have a list of options from which you can select one and only one. The problem is the selection to choose is not obvious without displaying more details on the option. If I use the disclosure indicator or button for the more detail, I lose the checkmark functionality. In searching around I see some have used the cell Image as a work around. I see others instead of using the standard disclosure button have created custom disclosure button looking like a checkmark. Haven't seen this one but is it viable (HIG) to add a button in the cell ('more info') to launch the next tableview. My thought was to use a disclosure indicator and on the second view in the navigation bar (where the edit button usually is) add a 'selectMe' button. I think I am probably manage to code either of the above, am just asking for information on what is the best (HIG) way. Example Option 1 Option 2 Option 3 (x) Option 4 Where x is the checked one But in order to know which is the best choice you need to see Option 3 (Header) Option 3-a Option 3-b Option 3-c Option 3-d Where even at this level option 3-c might have additional information. Any guidance you can provide would appreciated.

  • Is it really necessary to have a competely validated Mark Up and css for SEO purposes

    - by Hitesh Manchanda
    Hi , While validating my CSS on http://jigsaw.w3.org/css-validator/ I am getting following errors: 1.Property zoom doesn't exist : 1 1. 2.Property -webkit-transition doesn't exist : all 200ms ease-in all 200ms ease-in 3.Property opacity doesn't exist in CSS level 2.1 4.Property -moz-border-radius doesn't exist 5.Property -webkit-border-radius doesn't exist Is it really required to validate the MarkUp and CSS completely for SEO or these errors which mostly are browser specific can be ignored for now. If these errors have to removed can someone please suggest the way to do so also.

  • Mark assembly App_licenses.dll with AssemblyVersion (FxCop CA1016 rule)

    - by user295479
    Hello everyone, I'm trying to fulfil FxCop's rules in my web site. Since I use some Infragistics controls I have a licenses.licx file that turns into a "app_licenses.dll" assembly after publication. The problem is that this app_licenses.dll assembly does not comply with rule CA1016 (MarkAssembliesWithAssemblyVersion), and I should add an AssemblyVersion attribute to 'App_Licenses.dll'. I found I can add an AssemblyInfo file to my web site and then reference it from the web.config file as following: <compilers> <compiler language="c#;cs;csharp" extension=".cs" compilerOptions="C:\....\AssemblyInfo.cs" type="Microsoft.CSharp.CSharpCodeProvider,System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" warningLevel="4"> <providerOption name="CompilerVersion" value="v3.5" /> <providerOption name="WarnAsError" value="false" /> </compiler> </compilers> AssemblyInfo.cs contains: using System; using System.Reflection; using System.Runtime.InteropServices; using System.Resources; [assembly: AssemblyVersion("1.0.0.0")] [assembly: AssemblyFileVersion("1.0.0.0")] [assembly: NeutralResourcesLanguageAttribute("es-ES")] NeutralResourcesLanguageAttribute worked for another auto-generated dll in the web site (app_GlobalResources.dll) for another FxCop rule, but app_licenses.dll seems to ignore the assembly info and still pops up the same CA1016 error. Any help would be much appreciated.

  • C question: Padding bits in unsigned integers and bitwise operations (C89)

    - by Anonymous Question Guy
    I have a lot of code that performs bitwise operations on unsigned integers. I wrote my code with the assumption that those operations were on integers of fixed width without any padding bits. For example an array of 32 bit unsigned integers of which all 32 bits available for each integer. I'm looking to make my code more portable and I'm focused on making sure I'm C89 compliant (in this case). One of the issues that I've come across is possible padded integers. Take this extreme example, taken from the GMP manual: However on Cray vector systems it may be noted that short and int are always stored in 8 bytes (and with sizeof indicating that) but use only 32 or 46 bits. The nails feature can account for this, by passing for instance 8*sizeof(int)-INT_BIT. I've also read about this type of padding in other places. I actually read of a post on SO last night (forgive me, I don't have the link and I'm going to cite something similar from memory) where if you have, say, a double with 60 usable bits the other 4 could be used for padding and those padding bits could serve some internal purpose so they cannot be modified. So let's say for example my code is compiled on a platform where an unsigned int type is sized at 4 bytes, each byte being 8 bits, however the most significant 2 bits are padding bits. Would UINT_MAX in that case be 0x3FFFFFFF (1073741823) ? #include <stdio.h> #include <stdlib.h> /* padding bits represented by underscores */ int main( int argc, char **argv ) { unsigned int a = 0x2AAAAAAA; /* __101010101010101010101010101010 */ unsigned int b = 0x15555555; /* __010101010101010101010101010101 */ unsigned int c = a ^ b; /* ?? __111111111111111111111111111111 */ unsigned int d = c << 5; /* ?? __111111111111111111111111100000 */ unsigned int e = d >> 5; /* ?? __000001111111111111111111111111 */ printf( "a: %X\nb: %X\nc: %X\nd: %X\ne: %X\n", a, b, c, d, e ); return 0; } is it safe to XOR two integers with padding bits? wouldn't I XOR whatever the padding bits are? I can't find this behavior covered in C89. furthermore is the c var guaranteed to be 0x3FFFFFFF or if for example the two padding bits were both on in a or b would c be 0xFFFFFFFF ? same question with d and e. am i manipulating the padding bits by shifting? I would expect to see this below, assuming 32 bits with the 2 most significant bits used for padding, but I want to know if something like this is guaranteed: a: 2AAAAAAA b: 15555555 c: 3FFFFFFF d: 3FFFFFE0 e: 01FFFFFF Also are padding bits always the most significant bits or could they be the least significant bits? Thanks guys EDIT 12/19/2010 5PM EST: Christoph has answered my question. Thanks! I had also asked (above) whether padding bits are always the most significant bits. This is cited in the rationale for the C99 standard, and the answer is no. I am playing it safe and assuming the same for C89. Here is specifically what the C99 rationale says for §6.2.6.2 (Representation of Integer Types): Padding bits are user-accessible in an unsigned integer type. For example, suppose a machine uses a pair of 16-bit shorts (each with its own sign bit) to make up a 32-bit int and the sign bit of the lower short is ignored when used in this 32-bit int. Then, as a 32-bit signed int, there is a padding bit (in the middle of the 32 bits) that is ignored in determining the value of the 32-bit signed int. But, if this 32-bit item is treated as a 32-bit unsigned int, then that padding bit is visible to the user’s program. The C committee was told that there is a machine that works this way, and that is one reason that padding bits were added to C99. Footnotes 44 and 45 mention that parity bits might be padding bits. The committee does not know of any machines with user-accessible parity bits within an integer. Therefore, the committee is not aware of any machines that treat parity bits as padding bits. EDIT 12/28/2010 3PM EST: I found an interesting discussion on comp.lang.c from a few months ago. Bitwise Operator Effects on Padding Bits (VelocityReviews reader) Bitwise Operator Effects on Padding Bits (Google Groups alternate link) One point made by Dietmar which I found interesting: Let's note that padding bits are not necessary for the existence of trap representations; combinations of value bits which do not represent a value of the object type would also do.

  • Apostrophe turning to question mark when using php handler in .htaccess

    - by Tony Deefer
    I have a .htm page on a site, that for reasons I won't go into cannot be renamed .php I have added some php code to the top of the page, (sets a cookie and redirects to another page) and added the following to .htaccess to parse the .htm file as php AddHandler application/x-httpd-php5 .html .htm As soon as this is added to .htaccess all apostrophe's change into questions marks. Using charset UTF-8 Can anyone offer a solution that does not involve renaming the file .php? Many thanks

  • XCode 3.2 does not mark unit test assert failures in the editor

    - by Cliff
    I've been off in Java land for about a month or so and now, upon returning to XCode I feel lost. I've upgraded 1st to 3.1.2 then recently to 3.2 and also got a new Mac with Snow Leopard so I'm not exactly sure when the problem surfaced. I just know that I used to get little red bubbles in my unit test next to the failing asserts and that no longer seems to happen. Is there a way to restore this? I've been trying to use Apple's own SenTesting framework instead of GoogleTools for mac like I used to. Should I revert to Google Tools? Does anyone have an answer?

  • Dojo Tooltips missing the mark sometimes

    - by kbeck
    Hi everyone, I'm using tooltips for icons that are displayed in a dijit.Dialog. Sometimes they work just fine, but other times they get placed around 25 to 50 pixels further away from the target than they should be. I can't see any pattern to when this happens. Any ideas on why the screen placement would be varying in this way? Thanks, Karl

  • Using explicitly numbered repetition instead of question mark, star and plus

    - by polygenelubricants
    I've seen regex patterns that use explicitly numbered repetition instead of ?, * and +, i.e.: Explicit Shorthand (something){0,1} (something)? (something){1} (something) (something){0,} (something)* (something){1,} (something)+ The questions are: Are these two forms identical? What if you add possessive/reluctant modifiers? If they are identical, which one is more idiomatic? More readable? Simply "better"?

  • Alternative for table mark-up in ASP.NET not working properly

    - by yetanothercoder
    Using Visual WebDeveloper 2010 Express and ASP.NET 4.0 Don't know whether its relevant but the whole thing is in a ContentPlaceHolder and inside an UpdatePanel. To avoid using the old table tr td model, I have created a simple form like this <div class="admin-form"> <asp:Label ID="UserNameLabel" runat="server" CssClass="form-label" Text="User Name" /> <asp:TextBox ID="UserNameText" runat="server" Width="200px"/> <br /> <asp:Label ID="PasswordLabel" runat="server" CssClass="form-label" Text="Password" /> <asp:TextBox ID="PasswordText" runat="server" TextMode="Password" Width="200px"/> <br /> <asp:Label ID="ConfirmPasswordLabel" runat="server" CssClass="form-label" Text="Confirm Password" /> <asp:TextBox ID="ConfirmPasswordText" runat="server" TextMode="Password" Width="200px"/> <br /> <asp:Label ID="EmailLabel" runat="server" CssClass="form-label" Text="Email" /> <asp:TextBox ID="EmailText" runat="server" Width="200px"/> <br /> <br /> <br /> <span class="form-label"></span> <asp:Button ID="CreateUserButton" runat="server" CssClass="button blue" Text="Create New User"/> </div> And the CSS .form-label { width: 300px !important; } This renders incorrectly as I would like to have all textboxes vertically lined after taking 300px. What is wrong? P.S: I cannot use HTML Controls like label as I have resx for globalization

  • Question about API and Web application code sharing

    - by opendd
    This is a design question. I have a multi part application with several user types. There is a user client for the patient that interacts with a web service. There is an API evolving behind the web service that will be exposed to institutional "users" and an interface for clinicians, researchers and admin types. The patient UI is Flex. The clinician/admin portion of the application is RoR. The API is RoR/rack based. The web service component is Java WS. All components access the same data source. These components are deployed as separate components to their own subdomains. This decision was made to allow for scaling the components individually as needed. Initially, the decision was made to split the code for the RoR Web application from the RoR API. This decision was made in the interests of security and keeping the components focused on specific tasks. Over the course of time, there is necessarily going to be overlap and I am second guessing my decision to keep the code totally separate. I am noticing code being lifted from the admin side being lifted, modified and used in the API. This being the case, I have been considering merging the Ruby based repositories. I am interested in ideas and insight on this situation along with the reasoning behind your thoughts. Thanks.

  • Regex syntax question - trying to understand

    - by Asaf Chertkoff
    i don't know if this question belong here or no, but it is worth a shot. i'm a self taught php programmer and i'm only now starting to grasp the regex stuff. i'm pretty aware of its capabilities when it is done right, but this is something i need to dive in too. so maybe someone can help me, and save me so hours of experiment. i have this string: here is the <a href="http://www.google.com" class="ttt" title="here"><img src="http://www.somewhere.com/1.png" alt="some' /></a> and there is <a href="#not">not</a> a chance... now, i need to perg_match this string and search for the a href tag that has an image in it, and replace it with the same tag with a small difference: after the title attribute inside the tag, i'll want to add a rel="here" attribute. of course, it should ignore links (a href's) that doesn't have img tag inside. help will be appreciated, thanks.

  • MMO Data Persistence Question

    - by JasonG
    I wanted to ask a question regarding data persistence strategies for an MMO. I have some experience in the games industry with social synchronous games. At Zynga, we stored static proto data in XML on both the client and the server and stored instance/runtime data in membase. For clarity sake, proto data for a Potion would be PotionName or MaxCharges, while runtime/instance data would be something like ChargesRemaining. So basically, if a player picks up a potion the instance is (via prediction) created from XML data on the client, the request gets sent to the server where the instance is created from XML and then added to membase. Is the same strategy that would be used for soemthing like an MMO? Would it be feasible to have static proto data in some kind of in-memory no-sql database on both client and server with instance data being stored on the server in a more enterprise level database? Or should all data (proto/instance) be stored on the server and the client gets everything from server? I know a lot of this might on certain game requirements, however, i'm basically looking for some general opinion/best practices here if there are any.

  • Dalvik + Java licensing question

    - by Andrew Bate
    This is a licensing question about the Dalvik and J2SE core libraries. In particular the license governing java.util.concurrent.SynchronousQueue. The license header of the class in the JDK source states that it is GPLv2 only (see grepcode). However, the same file in the Dalvik core libraries seems to be governed by the Apache 2 license only (see android source). How is this possible? I didn't think you could take GPLv2 source and re-license it as Apache 2. (It's obvious they did: a comment above the Java Doc even says "removed link to collections framework docs"!) I'm asking because I have a GPLv3 project and would like to include a derivative work of some source from the core libraries (either Dalvik or J2SE) but publish it under GPLv3. I thought I could do this with Apache 2, but not GPLv2. I know that the J2SE class source is itself derivative work from public domain source, but the changes from the original are substantial. (The original is available at gee.cs.oswego.edu if you are interested.) Therefore the android source really is just a copy of the J2SE source, but published under Apache 2 instead of GPLv2. Is Google really allowed to do this?

  • yet another question about migrating to Java

    - by aloneguid
    Hi, There are plenty similar questions, but maybe responses to this one will save a developer's life :) I want to migrate to Java. The reasons are very clear: all the .NET vacancies are client and windows oriented (Silverlight developer, ASP.NET developer, WPF developer etc.) and none of them are any interest to me. I worked with .NET since it's beginning as our company decided to invest in .NET having C++ stack and all the natual problems, so I was just blindly following and actually enjoyed it as the products were mostly server oriented with mixed C++/C# code. Today I have beforementioned problem - can't find an inspiring job. I'd rather kill myself than start working on a Silverlight or WPF project. Searching Java vacancies shows promising results, however they all require a huge java-related technology stack and experience. The question is is there any chance to find a job quickly and without dramatic salary drop (I know that Java guys are usually better paid, so there must be a kind of a credit) and if not, how must time and effort does it take to migrate (my .NET knowledge mostly includes server-oriented technologies like NHibernate, WCF, threading, sockets, ASP.NET web services, Enterprise Library, NInject etc etc etc, and (still) some C++ leftovers). Thanks!
