• unzip error "End-of-central-directory signature not found"

  - by Tim

  I try to unzip a zip file, but got an error: $ unzip COCR2_100.zip Archive: COCR2_100.zip End-of-central-directory signature not found. Either this file is not a zipfile, or it constitutes one disk of a multi-part archive. In the latter case the central directory and zipfile comment will be found on the last disk(s) of this archive. note: COCR2_100.zip may be a plain executable, not an archive unzip: cannot find zipfile directory in one of COCR2_100.zip or COCR2_100.zip.zip, and cannot find COCR2_100.zip.ZIP, period. I googled but didn't find a solution. I was wondering why it is and how I should fix it? Thanks! The zip file can be downloaded from COCR2_100. It is an application, and here is its website http://users.belgacom.net/chardic/cocr2.html. My OS is 10.10.

• Is it safe to Block These URLs with Robots.txt?

  - by Edgar Quintero

  I have a website that has all URLs optimized and 301 redirected from nasty URLs to clean ones. However, everywhere throughout the site the unclean URLs are linked in menus, content, products, etc. Google currently has all clean URLs indexed, along with a few unclean URLs too. So the site still has linked everywhere the old URLs (ideally this wouldn't be the case but this is how it is ATM). I would like to block the unclean URLs with robots.txt. The question: If I block these unclean URLs with the robots.txt, when the entire website is linked with them (but they all redirect to the clean version), will this affect the indexing status at all?

• Switching to HTTPS - redirect question

  - by seengee

  Following the recent Google announcements about improved ranking for sites running on https we have a number of clients asking about this. Is it safe to just 301 redirect all pages to their SSL equivalent, for example in a common PHP include file: if($_SERVER['HTTPS']!="on"){ $redirect= "https://".$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI']; header("Location:$redirect",true,301); exit(); } Obviously I'm aware this is also possible within a .htaccess file but that cannot be modified in our case. Obviously all internal links would be switched to https:// links but obviously we need to sort out incoming links from Google and elsewhere. Is this a sound approach? Are there any other gotchas to be aware of?

• Find Nearest Object

  - by ultifinitus

  I have a fairly sizable game engine created, and I'm adding some needed features, such as this, how do I find the nearest object from a list of points? In this case, I could simply use the Pythagorean theorem to find the distance, and check the results. I know I can't simply add x and y, because that's the distance to the object, if you only took right angle turns. However I'm wondering if there's something else I could do? I also have a collision system, where essentially I turn objects into smaller objects on a smaller grid, kind of like a minimap, and only if objects exist in the same gridspace do I check for collisions, I could do the same thing, only make the gridspace larger to check for closeness. (rather than checking every. single. object) however that would take additional setup in my base class and clutter up the already cluttered object. TL;DR Question: Is there something efficient and accurate that I can use to detect which object is closest, based on a list of points and sizes?

• Are the National Computer Science Academy certifications worth it?

  - by Horacio Nuñez

  I have a question regarding the real value of having NCSA's certifications. Today I reach their site and I easily passed the JavaScript certification within minutes, but I never reach questions related to Literal Javascript Notation (Json), closures or browser specific APIs. This facts let me to doubt a bit of the real value of the test (and the proper certification you can have if you pay them $34), but maybe Im wrong and just earned a respected certification within the States for easy questions... in which case I can spend some time doing other certifications on the same site. Did you have an NCSA certification and think is worth having it in your resume, or you know of a better certification program?

• getting the user back where they came from with mod_form_auth

  - by bmargulies

  Using the mod_form_auth module in Apache HTTPD 2.4.3, I am looking for a way to have the user redirected to their original desired target after completing a login. That is, if I have a <Location /protected> ... form auth config here </Location> the user might browse to /protected/a, or to protected/b. In either case, they will be presented with the login form. However, as far as I can see, I must specific a single 'success' URL. I'm wondering if I'm missing some Apache feature that would allow me to, for example, cause the redirect to the login form go to something like: https://login.html?origTarget=/protected/a via some syntax on the AuthForLoginRequiredLocation statement?

• What's the recommended way of doing a HUD for an android game?

  - by joxnas

  Basically the question is in the title. I'm creating a RTS game and I will need buttons like attack move / attack ground, etc. I am not using any engine. When people do games in OpenGL for android (my case), do they ever use android components to control the game or do they create their components in the game? What are the general recommended approach, if there's any? How about more complex components like scrolling lists of items , etc? I would also appreciate you to pair your answer with a brief comment about how was your experience using the approach(es) you describe. Thanks :)

• How to name a method that both performs a task and returns a boolean as a status?

  - by Limbo Exile

  If there is a method bool DoStuff() { try { // doing stuff... return true; } catch (Exception ex) { return false; } } should it rather be called IsStuffDone()? Both names could be misinterpreted by the user: If the name is DoStuff() why does it return a boolean? If the name is IsStuffDone() it is not clear whether the method performs a task or only checks its result. Is there a convention for this case? Or an alternative approach, as this one is considered flawed? For example in languages that have output parameters, like C#, a boolean status variable could be passed to the method as one and the method's return type would be void.

• ubuntu 12.04 how do I select a custom program to open specific file type

  - by user68477

  I want to set a filetype to be opened by a specific program other than ubuntu's default. I usually right click properties open with and select the application I need. This however does not work in this case. The application I want is not shown in the "open with" dialog and there apparently is no way I can browse to it or type in a custom command like I used to in 10.04. Is this a bug that I should file or a feature that can be worked around?

• Alternative to "inheritance versus composition?" [closed]

  - by Frank

  Possible Duplicate: Where does this concept of “favor composition over inheritance” come from? I have colleagues at work who claim that "Inheritance is an anti-pattern" and want to use composition systematically instead, except in (rare, according to them) cases where inheritance is really the best way to go. I want to suggest an alternative where we continue using inheritance, but it is strictly forbidden (enforced by code reviews) to use anything but public members of base classes in derived classes. For a case where we don't need to swap components of a class at runtime (static inheritance), would that be equivalent enough to composition? Or am I forgetting some other important aspect of composition?

• Deferred contexts and inheriting state from the immediate context

  - by dreijer

  I took my first stab at using deferred contexts in DirectX 11 today. Basically, I created my deferred context using CreateDeferredContext() and then drew a simple triangle strip with it. Early on in my test application, I call OMSetRenderTargets() on the immediate context in order to render to the swap chain's back buffer. Now, after having read the documentation on MSDN about deferred contexts, I assumed that calling ExecuteCommandList() on the immediate context would execute all of the deferred commands as "an extension" to the commands that had already been executed on the immediate context, i.e. the triangle strip I rendered in the deferred context would be rendered to the swap chain's back buffer. That didn't seem to be the case, however. Instead, I had to manually pull out the immediate context's render target (using OMGetRenderTargets()) and then set it on the deferred context with OMSetRenderTargets(). Am I doing something wrong or is that the way deferred contexts work?

• I'm getting a black screen right after Install Ubuntu option on GRUB menu. Any ideas?

  - by Silight

  I've formatted my USB and remade the live USB twice. I tried editing editing the commands (pressing the 'e' key while the command was highlighted on the GRUB menu) by 1. deleting quiet splash and replacing it with nomodeset 2. adding nomodeset right before quiet splash 3. deleting quiet splash and adding radeon.modeset=0 I saw another solution for a fix by editing GRUB but in command line 'sudo' 'nano' and 'update-grub' all show up as unknown commands. I'm brand new to Ubuntu, in case you couldn't tell. I would appreciate any help you could give me. I want to convince my brother that Ubuntu is a better option than iOS but I can't do that if I can't install it. If you need more information, please ask. I'm not dual booting. I want this to be a full install. Thanks.

• PHP, when to use iterators, how to buffer results?

  - by Jon L.

  When is it best to use Iterators in PHP, and how can they be implemented to best avoid loading all objects into memory simultaneously? Do any constructs exist in PHP so that we can queue up results of an operation for use with an Iterator, while again avoiding loading all objects into memory simultaneously? An example would be a curl HTTP request against a REST server In the case of an HTTP request that returns all results at once (a la curl), would we be better off to go with streaming results, and if so, are there any limitations or pitfalls to be aware of? If using streaming, is it better to replace curl with a PHP native stream/socket? My intention is to implement Iterators for a REST client, and separately a document ORM that I'm maintaining, but only if I can do so while gaining benefits from reduced memory usage, increased performance, etc. Thanks in advance for any responses :-)

• Fastest way to set up a JSON server on my local machine [closed]

  - by Mohsen

  I am a front-end developer. For many experiements I do I need to have a server that talks JSON with my client side app. Normally that server is a simple server that response to my POSTs and GETs. For example I need to setup a server that saves, modifies and read data from a "library" database like this: POST /books create a book GET /book/:id gets a book and so on... What is the fastest to set up and easiest technology stack for database and server in this case? I am open to use Ruby, Nodejs and anything that do the job fast and easy. Is there any framework (on any language) that do stuff like this for me?

• Queuing rpc calls

  - by alfa64

  i'm designing a system wich listen to json rpc calls from clients, piles it up inside a list, and if it gets full it should store them in a DB and keep recieving calls. My original plan is to listen to the rpc calls from Perl with the json-rpc and put them in the array. The clients do some long polling in another server to get responses as they appear. What is this blocking/noblocking thing? Should i do a script for node.js to listen to the calls? What do you think is a good practice in this case? The objective is to listen as much calls as possible.

• Best practices for upgrading user data when updating versions of software

  - by Javy

  In my code I check the current version of the software on launch and compare it to the version stored in the user's data file(s). If the version is newer, then I call different methods to update the old data to the newer data version, if necessary. I usually have to make a new method to convert the data with each update that changes user data in some way, and cannot remove the old ones in case there was someone who missed an update. So the app must be able to go through each method call and update their data until they get their data current. With larger data sets, this could be a problem. In addition, I recently had a brief discussion with another StackOverflow user this and he indicated he always appended a date stamp to the filename to manage data versions, although his reasoning as to why this was better than storing the version data in the file itself was unclear. Since I've rarely seen management of user data versions in books I've read, I'm curious what are the best practices for naming user data files and procedures for updating older data to newer versions.

• Marketing for Scheduled Online Events

  - by JT703

  Last year I started working with a team on our first major web project (We, the Pixels). I believe the idea is very solid, but it has a hard requirement for a group of people being on the site for the randomly scheduled events. We are having problems getting people to come and stay for these events. What is the proper marketing approach needed to bring people to the site for these events? We have recently done the following in an attempt to fix the problem: Added email notification of new events being created Added privileges based on rank Added text throughout the site encouraging setting up the events in the future so other users can have time see that it exists. Gotten involved in with other communities that would find the site interesting in order to promote (market) the site Advertised using Google Adwords Is there an standard marketing approach for such a case as this?

• Can I use GPL software in a commercial application

  - by Petah

  I have 3 questions about the GPL here: If I use GPL software in my application, but don't modify or distribute it, do I have to release my application under the GPL? What if I modify some software that my application uses. Then do I have to release my application under the GPL, or can I just supply the modified software under the GPLs terms. And what if I use GPL software, but don't modify it, can I distribute it with my application? My case in point is, I have a PHP framework which I use the GeSHi library to highlight some output. Because GeSHi is GPL, does my framework have to be GPL? Can I modify GeSHi for particular use cases of my application if I supply the modifications back to the GeSHi maintainers? Can I redistribute my framework with GeSHi?

• Problems installing Ubuntu on unallocated space

  - by Adam

  I've been trying to install Ubuntu on some unallocated space, but I'm getting confused with the manual partition setup. I didn't want to try the other options for it suggested that everything on my drive would be erased (but I might be wrong) I have an old(ish) laptop with a 60GB hard-drive. Theres a Windows 7 partition of 30GB, followed by 20GB of unallocated space, then HP's Windows recovery partition of under 10GB. Do I need to format the empty space in windows first? What's the recommended method in this case?

• Making a collision detection system

  - by Sri Harsha Chilakapati

  I'm very new to game development (just started 3 months ago) and I've learning through creating a game engine. It's located here. In terms of collision, I know only brutefoce detection, in which case, the game slows down if there are a number of objects. So my question is How should I program the collisions? I want them to happen automatically for every object and call the object's collision(GObject other) method on each collision. Are there any new algorithms which can make this fast? If so, can anybody6 sh6ed some light on this topic? And I think of making it like the game maker Thanks

• How important is the unit test in the software development?

  - by Lo Wai Lun

  We are doing software testing by testing a lot if I/O cases, so developers and system analysts can open reviews and test for their committed code within a given time period (e.g. 1 week). But when it come across with extracting information from a database, how to consider the cases and the corresponding methodology to start with? Although that is more likely to be a case studies because the unit-testing depends on the project we have involved which is too specific and particular most of the time. What is the general overview of the steps and precautions for unit-testing?

• most efficient AABB vs Ray collision algorithms

  - by Asher Einhorn

  Is there a known 'most efficient' algorithm for AABB vs Ray collision detection? I recently stumbled accross Arvo's AABB vs Sphere collision algorithm, and I am wondering if there is a similarly noteworthy algorithm for this. One must have condition for this algorithm is that I need to have the option of querying the result for the distance from the ray's origin to the point of collision. having said this, if there is another, faster algorithm which does not return distance, then in addition to posting one that does, also posting that algorithm would be very helpful indeed. Please also state what the function's return argument is, and how you use it to return distance or a 'no-collision' case. For example, does it have an out parameter for the distance as well as a bool return value? or does it simply return a float with the distance, vs a value of -1 for no collision? (For those that don't know: AABB = Axis Aligned Bounding Box)

• Right-click acts too fast - No Fix Yet, Any Workaround?

  - by Aahan Krish

  When I click the right mouse button (anywhere, be it - desktop, browser, console, etc.), the right-click context menu pops up so quickly that the very *first* option in the menu gets clicked. This happens too often to take it easy. This issue has been brought up a couple of times on Ask Ubuntu, but with no fix whatsoever. This is a very low priority issue for the Ubuntu team, I believe? (How could they?!) Is there at least a workaround for the issue? Ubuntu is almost unusable for me as it is now. PS: I have a new mouse. So, please don't go about suggesting that I get a new one - - everything's working fine on Windows 7, so should be the case with ubuntu 11.10, which it is not.
