• Why compiz or unity refresh screen by every movement I do? [closed]

  - by Behzadsh

  It's getting me crazy! compiz or unity refresh screen (like I run compiz --replace or unity --replace) by every movement I do (e.g ctrl+tab, super+w) and somehow unexpectedly! sometimes it failed to reload title bar and keyboard functions like ctrl+tab and alt+F2 stop working, and I had no chance but reboot! Sometimes it work without any problem. I couldn't found any reason why this happen. I wanted to report a bug but I don't have enough information about it.

• Where would a senior PHP developer locate the method getActiveEntries()?

  - by darga33

  I have a class named GuestbookEntry that maps to the properties that are in the database table named "guestbook". Very simple! Originally, I had a static method named getActiveEntries() that retrieved an array of all GuestbookEntry objects. Each row in the guestbook table was an object that was added to that array. Then while learning how to properly design PHP classes, I learned some things: Static methods are not desirable. Separation of Concerns Single Responsibility Principle If the GuestbookEntry class should only be responsible for managing single guestbook entries then where should this getActiveEntries() method most properly go? Update: I am looking for an answer that complies with the SOLID acronym principles and allows for test-ability. That's why I want to stay away from static calls/standard functions. DAO, repository, ...? Please explain as though your explanation will be part of "Where to Locate FOR DUMMIES"... :-)

• Is server validation necessary with client-side validators?

  - by peroija

  I recently created a .net web app that used over 200 custom validators on one page. I wrote code for both ClientValidationFunction and OnServerValidate which results in a ton of repetitive code. My sql statements are parameterized, I have functions that pull data from input fields and validates them before passing to the sql statements or stored procedures. And the javascript validates the fields before the page submits. So essentially the data is clean and valid before it even hits the OnServerValidate and clean after it anyways due to the aforementioned steps. This makes me question, is OnServerValidate really needed when I validate on the clientside?

• Top X tips to code & debug efficiently [closed]

  - by user1510230

  I'm starting a big Java project and I wanted to have some advices that could benefit us all. What are the X (X could be 5 / 10 / ... or even 100 :) most important tips to code and debug efficiently in general (and in particular with java / javascript) ? I'll start with some basic ones : Use functions everytime a portion of code is used more than twice. Try not to code features with more than 15 lines of code in one shot. Rather write 5 lines of code then check if they work correctly then write 5 more... and so on start with the outcome of the function and then code it backwards (bottom-top approach) ... Thanks everybody

• Web Search for a Hard Drive

  - by zecougar

  Here is the situation. Our organization has a fair amount of data in the form of documents, images, videos stored on a intranet server. We need to be able to expose these documents via some sort of search functionality on the intranet. Provide some mechanism to organize and tag the documents on hard disk. Ideally we'd also like to provide a unified search across documents on the google apps for business instance that we have. Any ideas on how to approach this problem ?

• What are the pros and cons of Coffeescript?

  - by Philip

  Of course one big pro is the amount of syntactic sugar leading to shorter code in a lot of cases. On http://jashkenas.github.com/coffee-script/ there are impressive examples. On the other hand I have doubts that these examples represent code of complex real world applications. In my code for instance I never add functions to bare objects but rather to their prototypes. Moreover the prototype feature is hidden from the user, suggesting classical OOP rather than idiomatic Javascript. The array comprehension example would look in my code probably like this: cubes = $.map(list, math.cube); // which is 8 characters less using jQuery...

• Script to create dynamic PIVOT queries in SQL Server

  Pivoting is a common reporting requirement - data is stored in columns and you need to present it in rows. This was a nice feature that was added to SQL Server, but you don't always know all of the values you need to pivot on. This tip looks at how you can dynamically create the pivot command to handle these unknown values. Top 5 hard-earned lessons of a DBAIn part one, read about ‘The Case of the Missing Index’ and learn from the experience of The DBA Team. Read now.

• Where in a typical rendering pipeline does visibility and shading occur?

  - by user29163

  I am taking a computer graphics course. The book and the lecture notes are vague on the on the order of flow between the different steps in the rendering process. For example, if we have specified a view in a scene, and then want to perform a projection transformation for that given view, then we have to go through a sequence of transformations. In the end we end up with a normalized "viewcube" ready to be mapped 2D after clipping. But why do we end up with a cube (ie 3D thing), when a projection results in projecting the 3D objects to 2D. (depth information is lost?) The other line of reasoning is that all information further needed is stored within the "cube" and that visibility detection and shading is performed with respect to this cube and then we perform rasterezation.

• How to separate and maintain customer specific code

  - by WYSIWYG

  I am implementing customer specific code and currently following simple approach like if (cusomterId == 23) do it. I want to separate out all the customer related code in separate place. But I have following problems. In code is in 1. Stored procs 2. Plain old classes. 3. Controllers 4. Views I came up with two solutions. First is to create table CustomerFunctionlity with columns CustomerId, FunctionalityName, method/Proc, inputs/outputs With this table I can simply check if exists, execute given function. Another way is creating a factory which returns customer related object for an interface. I am writting small end to end customer specific functionalities. How can I write maintenable code. Thanks

• How to access the SD card through my Sony Ericsson Xperia Arc Phone?

  - by user16364

  I have a Sony Ericsson Xperia Arc phone and I cannot access its SD card through the USB cable provided. I have set the USB connection mode to MSC yet when I connect the phone to my computer I cannot see the SD card (or anything for that matter). The Disk Utility however, does see an SEMC Mass Storage device but it says that no media was detected. I have validated that the SD card works as I removed it from the camera and plugged it into a card reader and saw all the photos and files stored on it. I have validated that the phone works as I have connected it (in MSC mode) to my wife's Windows 7 computer. Can anyone please tell me how I can access the SD card on my phone.

• Looking to create a website ... need assistance on what technologies to use!

  - by rsala004

  First off, My group and I don't have any experience with databases or anything of that sort, only programming (not web-programming), so this post is just me wondering what things I should start researching and possibly some referral to a hosting company. The abstract idea is to have a list of things, each categorized, and each item with user-submitted reviews (made by users who are signed up with the website). Would absolutely everything be stored on a SQL database? (the long text reviews for example) Does anyone have any suggestions on some 'web frameworks' we could use to jumpstart us? What should our absolute first step be? (I was thinking about first designing the basic database? so we have something to work around...?) Should we worry about which host we choose right now, any recommendations? (would it be a trivial task to switch hosts in the future?) Thanks again, any help is appreciated!

• Vector normalization gives very imprecise results

  - by Kipras

  When I normalize vectors I receive very strange results. The lengths of the normalized vectors range from 1.0 to almost 1.5. The functions are all written by me, but I just can't find a mistake in my algorithm. When I normalize I just divide all components of the vector by the vector's length. public double length(){ return Math.sqrt(x*x + y*y); } public void normalize(){ if(length() > 0){ x /= length(); y /= length(); } } Is this supposed to happen? I mean I can see the length ranging from 0.9 to 1.1 at worst, but this is just overwhelming. Cheers

• How does Google store search trends in backend?

  - by Achshar

  Google trends shows what query has been searched how many times and some other properties of the said query. But how is this data stored in a database? Storing a new row for every search does not seem right. They also tell the query on a time graph, so they must have some way to look for individual searches made by users, but the number of queries they get every day, it does not feel right that they would store every search in a database row along with a time-stamp. This does not apply to just Google trends or Google in general but any other big site that gets awful number of queries and then has tools to see them in depth. I am not an expert on this but I am interested to know some high level structure of how things work behind the scenes.

• I believe my solution is better than my boss's, so should I ignore him?

  - by mahen23

  I'm working with php and sql. I think that my method of implementing functions is better than what my boss proposes. Just now he explained me how to do a check on a list of email addresses, and I do not like his idea. I proposed mine which is better and quicker to implement, but he disagreed. Now I think I will go ahead and implement my idea, because his idea was not clear enough to me. Do you think he will be mad?

• ASP.NET - Password Strength Indicator using jQuery and XML

  Last week, I had the opportunity to help implement and integrate a strong password policy into the legacy web application developed using ASP technology. The solution I proposed was to use jQuery to display the password strength meter to help users create strong passwords. One of my colleagues asked if we would have to modify multiple pages and files if the client decided to alter the password policy. The answer is no. Thanks to jQuery, the client-side script and code behind can share the same information. The password policy information is stored in an XML file and the client-side script and code behind are reading from this to perform the password strength validation.

• If you need more than 3 levels of indentation, you're screwed?

  - by jokoon

  Per the Linux kernel coding style document: The answer to that is that if you need more than 3 levels of indentation, you're screwed anyway, and should fix your program. What can I deduce from this quote? On top of the fact that too long methods are hard to maintain, are they hard or impossible to optimize for the compiler? I don't really understand if this quote encourages better coding practice or is really a mathematical / algorithmic sort of truth. I also read in some C++ optimizing guide that "dividing up a program into more functions improves its design" is frequently taught in CS courses, but it should be not done too much, since it can turn into a lot of JMP calls (even if the compiler can inline some methods by itself).

• C++ game architecture

  - by rxc

  I'm trying to make a game, but I'm not sure of the best way to set up the main loop and classes. For really small games, I could put everything in the main() loop, including event handling, collision checking, etc. However, for large games, that's seems like a highly inefficient way to get things done. The architecture I want is kind like the way the Minecraft coders did it (I quote Minecraft code because I've seen the source code when downloading MCP). They have objects entity classes EntityCow and EntityChicken and they have methods like onDeath(), onLivingUpdate(); and item classes like ItemSword have methods like onItemUse(). I've never seen these methods get called directly, but apparently, they get stored in a class called DataWatcher, which, I think "watches" all the data (as the name implies) and calls the appropriate methods in the objects. Is that how most games do it? If so, how is the DataWatcher class implemented? Any help or alternate suggestions is really appreciated.

• How should dependencies be managed across a modular application?

  - by bear

  Let's say that we have a structure like this: Application -- Modules --Module1 -- Controller -- PublicHelper --Module2 -- Controller -- PublicHelper Whereby a module's Public Helper can provide helper functions. In nearly every module helper, the helper needs to access another module's public helper methods. Let's say for instance, in a PHP application: Module1 provides functionality to create a sale, and as part of the class Module1PublicHelper extends AbstractModuleHelper { public function createSale($customerId, $param, $param) { $userPublicHelper = // grab an instance of the user public helper $currentUser = $userPublicHelper->getCurrentUser(); } } class Module2PublicHelper extends AbstractModuleHelper { public function getCurrentUser() { //do something return $user; } } In this situation, the method needs to obtain an instance, either new or whatever of the user public helper. Given that all of Module Public Helper classes are instantiated with a minimum set of constructor params, e.g. EntityManager, what would be the best way to get a copy of it? Obviously, we can't really inject the user public helper class into the class containing createSale One solution would be to use a service locator or registry, however, testing the application isn't exactly easy.

• (My) Sun Ray 3i

  - by user13346636

  Last week, some Sun Ray devices were shown at the LASDEC exhibition. Afterward, they were brought back to the Aoyama Center, but not all of them found a place to be stored. So, two days ago, Iwasaki-san, one of the co-workers I've been close to (and who was at the exhibition), put a Sun Ray 3i (all-in-one with 21.5" screen) on my (shared) desk. Yay! I managed to get a Japanese keyboard, and now I can access my card and cardless sessions from Germany, and the performance is just great, as good as when I work from home in Hamburg. That's the way my deskt looks now,almost as messy as my desk in Hamburg: And my back is very grateful.

• ignore this test

  - by Name

  http://markitup.jaysalvat.com/downloads/markupsets/wiki/set.js Here is a useful construct when trying to hide variables from the parent namespace. All the code within the function is contained in the private scope of the function, meaning it is allowed. So you've become comfortable with jQuery and would like to learn how to write your own plugins. Great! You're in the right spot. Extending jQuery with plugins and methods is very powerful and can save you and your peers a lot of development time by abstracting your most clever functions into plugins. This post will outline the basics, best practices, and common pitfalls to watch out for as you begin writing your plugin.

• What to use to make voice chat (and some more) on a web?

  - by Tunococ

  I am trying to make available on my website a voice chat for a small group of people that allows some other means to interact such as text messaging, photo sharing, file sharing, simple drawing and silly games. In other words, something similar to older MSN Messenger, but on the web. Any ideas on what to use? To clarify, I am looking for suggestions on languages and libraries to use. I want to be able to fully customize it as much as possible because I might want to add other (somewhat interesting) functions later. Low-level programming is fine if required, but platform dependency isn't that much preferred.

• System.getProperty("user.dir") cannot get my project root path ,but the path which my eclipse is located

  - by facebook-100005613813158

  As the title goes , I have class named GetException.java,inside it ,I read a xml file in a static code block like(Because this document is shared): static{ ... document = db.parse(new File(System.getProperty("user.dir")+"/src/exception/ExceptionCode.xml")); ... } To test if the file path is correct, I write a main function just inside GetException.java, it proves that the path is correct ,xml file can be read successfully. My project root dir is "/home/wuchang/workspace/MongodbI". But When this Class is loaded from other class,such as I called one of its static functions , it reports the error message: /home/mrs/??/eclipse/src/exception/ExceptionCode.xml (No such file or directory) /home/mrs/??/eclipse/ is actually my eclipse installation directory.So , I wander how System.getProperty("user.dir") returned the eclipse installation directory to me ,instead of my project root directory?
