  - by Hunter

  I have a paragraph, in that, some of the texts are surrounded with a specific html tag. I need to to find the text which are not surrounded by that specific html tag. For example AVG Antivirus for Smartphones and Tablets detects harmful apps and SMS. <font color='black'>AVG</font> Mobilation™ AntiVirus Pro for Android™ is a mobile security solution that helps protect your mobile device from viruses, malware, spyware and online exploitation in real-time. avg blah blah... I want to find the word AVG (case insensitive) which is not surrounded by <font color='black'> </font>. It can be part the word or single whole word. In the case of part of the text, the whole word containing the word AVG should not surrounded by that html tag How can I do it with Java?

• Looking for a few good C# interview problems.

  - by AngryHacker

  I do not want to ask candidates questions, but rather give them several problems to resolve. The reason for this is that I've seen people be excellent with theory, but when confronted by a real world c# issue, just couldn't hack it. These c# problems should be simple enough that it won't take more than 5-20 minutes to resolve, yet complicated enough that I'd be able to weed out candidates that can't code. Right now, I typically ask the applications to reverse a string and remove duplicates from a List. This alone weeds out a large number of people. Any other examples I could use?

• What sort of schema can I use to accommodate manual date based data entries?

  - by meder

  I have an admin where users from multiple properties can enter in monthly statistics for twitter/facebook followers. We do not have access to the real data/db so this is why a manual entry. The form looks like this: Type ( radio, select **one** only ): - Twitter - Facebook Followers/Fans ( textfield ): Property (dropdown): Hotel A, Hotel B Date Start: mm/dd/yyyy (textfield) Date End: mm/dd/yyyy (textfield) Question 1.1: Since I am only keeping track of month per month, the date start/end fields which I have already created might be too specific. Would it be a better idea just to have a start month/year and and month/year if that's the only thing I care about? Question 1.2: What schema could I use for month to month statistics if I were to change the date start and end textfields to start month/year and end month/year dropdowns?

• Should properties in C# perform a lot of work?

  - by Hamish Grubijan

  When a property is read from or is assigned to, one would not expect it to perform a lot of work. When setSomeValue(...) and getSomeValue(...) methods are used instead, one should not be that surprised that something non-trivial might be going on under the hood. However, now that C# gave the world Properties, it seems silly to use getter and setter methods instead. What is your take on this? Should I mark this Q as a community wiki? Thanks.

• Reading in MIPS external file so another file can use it?

  - by SkyWookie

  Hey all, I'm working on this final thing for my MIPS project and it's deceptively easy. I need to get a procedure (called feed) and let its main driver program use it by reading it in. I know that I'm supposed to use the call code 14 and .globl sym (I think) in order to feed it into the file and have it read it. I just need a basic tutorial or something, as I CANNOT find it on the Internet or in my book (just lists the call code, real helpful). Here's what I know: I need to use read, but I also need a file descriptor (don't know where to get it). I need to put the buffer in $a1 and the length in $a2. Well, that's about it. If there's any decent tutorial you could whip up or if there is one online that I don't see let me know please :). I just need a push in the right direction, I'm sure it can't be too difficult, just can't find any info on it!

• [jQuery] Get width of element after resizing it

  - by infinito

  Hello, Is it possible to get the size of an element after resizing it using $(el).css()? My code is: function resize() { $(".combobox").css('width', '100%'); var width = $(".combobox").width(); } I've get the real value of the combobox only after calling the function a second time. The first time is gets the width before executing $(".combobox").css('width', '100%'); I suppose this is fault of the DOM not being recreated after the .css(). Is there any way to force DOM reloading? Thanks in advance!

• how to render custom columns with a GenericTreeModel

  - by Giorgio Gelardi

  I have to display some data in a treeview. The "real" data model is huge and I cannot copy all the stuff in a TreeStore, so I guess I should use a GenericTreeModel to act like a virtual treeview. Btw the first column is the classic icon+text style and I think I should declare a column with a CellRendererPixbuf (faq sample), but I'm not sure what the model methods on_get_n_columns() and on_get_value() should return. It's both a Pixbuf and a string value for the same column. Any help will be appreciated.

• What scenarios/settings will result in a query on SQL Server (2008) return stale data

  - by s1mm0t

  Most applications rarely need to display 100% accurate data. For example if this stack overflow question displays that there have been 0 views, when there have really been 10, it doesn't really matter. This is one way that the (perceived) performance of applications can be improved, by caching results and therefore sometimes not showing 100% accurate results. There are some cases where the data does need to be 100% accurate though. So if I run the query select * from Foo I want to be sure that the results are not stale. Now depending on how my database is set up, other activity on the database, use of transactions and isolation levels etc this query may or may not be a true reflection of the world. What scenario's and settings can people think of that will result in this query returning stale results or given that another connection is part way through a transaction that has updated this table, how can I guarantee that when the above query returns, the results will be accurate.

• Comapring pitches with digital audio

  - by user2250569

  I work on application which will compare musical notes with digital audio. My first idea was analyzes wav file (or sound in real-time) with some polyphonic pitch algorithms and gets notes and chords from this file and subsequently compared with notes in dataset. I went through a lot of pages and it seems to be a lot of hard work because existing implementations and algorithms are mainly/only focus on monophonic sound. Now, I got the idea to do this in the opposite way. In dataset I have for example note: A4 or better example chord: A4 B4 H4. And my idea is make some wave (or whatever I don't know what) from this note or chord and then compared with piece of digital audio. Is this good idea? Is it better/harder solution? If yes can you recommend me how to do it?

• Why is rails called a dsl?

  - by b_ayan

  Recently, when I tried to explain why Rails is a DSL to an intern at my organisation, I was not able to articulate my reasonings to the effect I would like to. Maybe I do not understand the space well enough to teach the nuances. Redirecting him to Martin Fowler' article or the google ranked one InfoQ or other material has not helped much either. Can some explain why Rails is a DSL with an example / parallel situation which is not voodoo stuff for someone who is fairly new to the world of code? Understanding the ideology might also help in elaborating the intricacies of the rails ecosystem?

• does Apple allow template style apps to pass review?

  - by user1159677

  I have an app which will go to our clients and then they can have their clients install it. Meaning there would be multiple versions of the master app but with customization per client. example 200 of our clients get the master app and then can customize it (text and images only via web) Will Apple allow something like this? Is there another way to get around this distribution model? I guess a good example of it would be a real estate agent having an app that's customized and on the app store but it's still Brand XYZ's app. thanks in advance

• How to use default.ctp in cakephp

  - by Louis Stephens

  I just finished the "15 min Blog Post tutorial" included in the documentation for cakephp. I was asked for another tutorial to change the layout for first tutorial. However, I am fairly new to MVC programming/Cakephp and I have no real clue how to do so. Well, I know I need "default.ctp" placed in app/views/layouts/ and I presume I need to include to include my data? . . . I am really at a loss of what to do. I set up my default.ctp as I mentioned above, but when I go to localhost:9999/posts the layout is still the same. I guess I need to include a stylesheet (and if so, where?) I guess if someone can point me in the right direction to a beginner's guide to layout styling or how to use it I would greatly appreciate any help.

• Continue Drupal processing after page send.

  - by David

  I need to do some additional processing after a Drupal page has been sent. I know I could fire a background shell command, but I need the current Drupal execution context to be maintained. I've spent a lot of time looking, but I can't find any documentation in this regard. This is surprising because it must surely be a common requirement. The only real idea I have is to fire up Drupal (again) via a shell command (exec, etc) and supply it with a pseudo path which would invoke the continued processing. But this seems unnecessarily complex/wasteful. Any pointers greatly appreciated, tks.

• Ways to wrap 32-bit .dll so it will work in a 64-bit OS

  - by dcarlet101

  So, I've been using JPIB to communicate with GPIB devices in my java program. However, I have run into a snag. Newer systems are built on 64 bit OS's. However, the jpib.dll file is written in 32-bit. I can't think of any kind of calls that it would need to make that are truly 64-bit dependent. The real trouble here is that the JPIB project hasn't been updated since september of 2006. I've tried emailing the dev through SourceForge but I don't think I'll get anywhere with that. Does anyone know of any ways around this? Or know how (and could tell me how) to recompile the .dll into AMD-64 compliance?

• How can I represent URL (possibly including query string) as a filename in Java without obscuring the original URL?

  - by jerluc

  Is there any real way to represent a URL (which more than likely will also have a query string) as a filename in Java without obscuring the original URL completely? My first approach was to simply escape invalid characters with arbitrary replacements (for example, replacing "/" with "_", etc). The problem is, as in the example of replacing with underscores is that a URL such as "app/my_app" would become "app_my_app" thus obscuring the original URL completely. I have also attempted to encode all the special characters, however again, seeing crazy %3e %20 etc is really not clear. Thank you for any suggestions.

• Does this pattern have a name?

  - by LK7jb

  Disclaimer: I'm trying to learn proper OO programming/design, so I'm pretty new to this stuff. I guess this is a general design patterns question, but I'll base my example on a game engine or something that renders objects to the display. Consider the following: How can this sort of separation between physical objects (e.g., cubes, spheres, etc.) and the rendering mechanism be achieved in an extensible manner? This design is not set in stone, and perhaps I've got something wrong from the start. I'm just curious as to how a problem like this is solved in real world code.

• How to controll (and emulate) monitor/projector on Linux?

  - by klew

  I would like to write some C/C++ program to controll monitor/projector attached to my computer. I've googled around, but I couldn't find almost anything that would lead me in some direction. Do you know where I can learn about it? What I would like to do is to write "Hello world" on an external monitor. It would be also nice to have some "monitor emulator" that will act as physicaly attached monitor (or to write program to emulate it). I'm not sure if it is possible. I couldn't find anything like this. I'm working on Ubuntu 9.10 with Gnome.

• Is it possible to get download progress of video/image in HTML5 ?

  - by Janusz

  Hello, Almost every flash player has an option to display how much of buffer (or % of total video) is downloaded to the client. At the moment I don't see it in any implementation of html5 video player. The real problem I am trying to solve is to have a way of knowing % of downloaded asset (image/swf/video whatever). In flash its easy by using MovieClipLoader and bytesLoaded property. Is there any way of doing it in HTML/HTML5/Javascript (without relying on Flash) ? Thanks!

• is it a good idea to write tests for environments other than development?

  - by jcollum

  Let's say I have a (fairly typical) set of environments: PROD, UAT, QA, DEV. Is it a good idea to run your tests across all environments? Here's what I'm thinking of. I have a proc in SQL that my code depends on, I'll call it proc_getActiveCustomers. If that proc isn't present my app will go south real fast. So I write a test that checks for the existence of this proc in the database. Nothing new here. But when I then deploy my app to the QA environment, would I also want to have a test that checks that environment for the existence of proc_getActiveCustomers? I think this is a good idea but I've never heard much about testing in environments outside of development. Makes me wonder if there's some downside I'm not aware of. The direction that I'm going is to have a list of environments in code and then passing that environment into my unit test.

• jQuery AJAX functions

  I am using jQuery's load() function when getting a page to a div like that: content.php page is : <script type="text/javascript"> $(".content").load("asd.php"); </script> and asd.php is: <script type="text/javascript"> alert("Hello World"); </script> When load ajax finished alert() message appears 3 times. Actually it must appears only 1 time. So load() function get page 3 times. How can I get the page a time?

• How does * work in Python

  - by Deqing

  Just switched from C++ to Python, and found that sometimes it is a little hard to understand ideas behind Python. I guess, a variable is a reference to the real object. For example, a=(1,2,5) meaning a - (1,2,5), so if b=a, then b and a are 2 references pointing to the same (1,2,5). It is a little like pointers in C/C++. If I have: def foo(a,b,c): print a,b,c a=(1,3,5) foo(*a) What does * mean here? Looks like it expands tuple a to a[0], a[1] and a[2]. But why print(*a) is not working while print(a[0],a[1],a[2]) works fine?

• Is there a Ruby on Rails framework like equivalent for .NET development?

  - by wgpubs

  Answers like ASP.NET MVC or Entity Framework really aren't acceptable as they address just one aspect of the problem domain. I'm looking for a framework ... a REAL framework that gives me the same features out of the box that Rails does. As such it should include at minimum: MVC for presentation ORM Ability to provide simple configuration for whatever environment (dev, QA, Production, etc...) Migration like functionality Ability to generate code in all layers (similar to scaffolding like behavior, etc...) Project template so as to create similar functionality as the "rails my_app" command. Thanks.

• Are there actually lag times to remove an email address from "the system"? [closed]

  - by Alex Gosselin

  For example, you send an unsubscribe message to a legitimate company or a spam, they reply that they will remove you and it may take up to 72 hours to take effect. I find it hard to believe anything that simple could take more than 3/4 of a second to take effect system wide. Another example would be when you call the visa activation line, there is a "delay" of several minutes while they try to sell you some kind of insurance. Usually just as you get the point across that you don't want it they will tell you your card has been activated and let you go. Are these delays real?

• uitextfield secure

  - by D_R

  I have a UITexetField with "Secure" option enabled in InterfaceBuilder (used to enter a password). Then I try to read, what the user entered. (void)textFieldDidEndEditing:(UITextField *)textField{ NSString *txt = textField.text; int a = 0; } It works fine with iOS 5 but since I use it in iOS6, this method no longer works - neither in simulator, nor at the real device. It was called, but textField.text returns always an empty string. With other UITextFields, without "Secure" option, it works fine. Could somebody help me ?
