• Cloudflare displaying cached CSS in-line?

  - by esqew

  I recently enabled CloudFlare on my domain, and when I make HTML statements like this: <link href="css/main.css" rel="stylesheet" /> The CSS gets displayed in-line, like this: <style>body{padding-top:40px}span.light{font-weight:lighter!important}span.title{font-size:60px;line-height:1;letter-spacing:-1px;color:inherit}</style> When I update the file via FTP, the changes are not reflected, which leads me to believe that this is a caching issue. Is this due to CloudFlare? If so, how do I disable the behavior? EDIT I also came to the conclusion that caching is behind the behavior after being able to see changes in the page after re-naming the CSS file.

• How to stop running pidgin at logins and disable window hiding feature?

  - by Behzadsh

  Every time I login into my desktop, pidgin start behind, and sometimes it's bothering me - e.g. when I'm not connected to Internet or when I don't want to be on-line - I check startup application list and there's no pidgin listed. another thing that is very bothering is hiding window feature or what ever it called. assume that you're using MusicTracker plug-in, your status is Busy and you're chatting with someone. when music change, status will change, and then buddy-list will disappear and chat window will minimize. Buddy-list is not important but minimizing chat window when you're chatting is bothering, Is there any way to make pidgin stop that?

• Why do spammers use CELESTRON NEXTAR 6SE?

  - by fmz

  I am running a website for a volunteer organization that hosts an annual event. There is a form where people can volunteer to bring items for the event. All too frequently I get spam from users across the globe that enter things like this: Country - 1: Australia Material - 1: CELESTRON NEXTAR 6SE Country - 2: Australia Material - 2: C8 Newton Country - 3: Australia Material - 3: ETX 125EC Country - 4: Australia Material - 4: ETX 125EC Country - 5: Australia Material - 5: CELESTRON NEXTAR 6SE I don't really care about the country, but what is it with the telescope stuff? Is there some hidden meaning behind all this or is it some astronomy group that moonlights as spammers?

• What makes C so popular in the age of OOP?

  - by GradGuy

  I code a lot both in C and C++ but did not expect C to be the second popular language, slightly behind Java! http://www.tiobe.com/index.php/content/paperinfo/tpci/index.html I'm curious as why, in this age of OOP, C is still all that popular? Note that 4 out of top 5 popular languages are all "modern" object-oriented capable languages. Now I agree that you can do OOP in C to some extend, but that's sort of painful and not quite elegant! (well at least compared to C++ I guess) So what makes C this popular? efficiency? being low-level? or the vast majority of libraries that already exist? ... or something else?

• How can I reverse ruby's include function.

  - by Glen

  I'll explain what i'm looking for in code as thats probably the most succinct: module Mixin def method puts "Foo" end end class Whatever include Mixin end w = Whatever.new w.method => "Foo" # some magic here w2 = Whatever.new w.method => NoMethodError I had tried just undefining the Mixin module using remove_const, but this doesn't seem to make any difference to Whatever. I had assumed that #include just added a reference to the module into the class's method resolution chain - but this behaviour doesn't agree with that. Can anyone tell me what include actually does behind the scenes, and how to reverse this?

• How can I compute the Big-O notation for a given piece of code?

  - by TheNew Rob Mullins

  So I just took a data structure midterm today and I was asked to determine the run time, in Big O notation, of the following nested loop: for (int i = 0; i < n-1; i++) { for(int j = 0; j < i; j++2) { //1 Statement } } I'm having trouble understanding the formula behind determining the run time. I thought that since the inner loop has 1 statement, and using the series equation of: (n * (n - 1)) / 2, I figured it to be: 1n * (n-1) / 2. Thus equaling (n^2 - 1) / 2. And so I generalized the runtime to be O(n^2 / 2). I'm not sure this is right though haha, was I supposed to divide my answer again by 2 since j is being upped in intervals of 2? Or is my answer completely off?

• Any pre-rolled System.IO abstraction libraries out there for Unit Testing?

  - by Binary Worrier

  To test methods that use the file system we need to basically put System.IO behind a set of interfaces that we can then mock, I do this with a DiskIO class and interface. As my DiskIO code gets larger (and the grumblings from the we're unconvinced about this TDD thing crowd here in work get louder), I went looking for a comprehensive open source library that already does this and found . . . nothing. I may be looking in the wrong place or have approached this problem in completely the wrong way. I can't be the only idiot in this position, do these libraries exist, if so where are they? Any you've used and would recommend? Thanks P.S. I'm happy with my current approach i.e. starting with what we need, and adding only when the need arises. Unfortunately the we're unconvinced about this TDD thing crowd remain unconvinced, and think that I can't be right.

• How to add ONLY system tray icon to application?

  - by badpanda

  I am developing an application that will be running behind the scenes in Windows and would like to put an icon in the system tray for troubleshooting purposes (simple way for users to tell if the app is running). There is no other UI for the application, and the icon does not need to have any functionality as of right now. All of the solutions I have found as of yet involve creating a form. I am wondering if there is a way to simply add a class to my current C# code that allows me to control the icon, rather than doing the whole 'make a form, set it to be invisible....' nonsense that seems to be the popular suggestion on the forums. Something along the lines of the way that UI control is done in say, Swing for Java. I would really appreciate any ideas! (Sorry if this is a n00b question...I haven't used C# before...) Thanks! badPanda

• Getting Started with Component Architecture: DI?

  - by ashes999

  I just moved away from MVC towards something more component-architecture-like. I have no concept of messages yet (it's rough prototype code), objects just get internal properties and values of other classes for now. That issue aside, it seems like this is turning into an aspect-oriented-programming challenge. I've noticed that all entities with, for example, a position component will have similar properties (get/set X/Y/Z, rotation, velocity). Is it a common practice, and/or good idea, to push these behind an interface and use dependency injection to inject a generic class (eg. PositionComponent) which already has all the boiler-plate code? (I'm sure the answer will affect the model I use for message/passing)

• Hiring developers - listing IDE as a requirement?

  - by suslik

  I've been looking at some job postings and noticed that a fair amount of them list IDEs under the 'required skills' section, even for senior positions. This is not localized to one company either, but rather it's something that comes up once in every few postings. I am perplexed by this job requirement, as my mentors and some of the best coders I've seen in my life were VIM/Emacs ninjas. Similarly, when I work with people I don't much care what tools they use as long as they are productive on the team. Can someone please explain the rationale behind hiring managers making IDEs an official job requirement?

• Miracles in your work

  - by MobileDev123

  Lot of things has been discussed that can be taken as negative things about programmers, Lets discussed about something good and unexpected happenings in your programmer life... Like: (after R&D of two days and a lot of disappointments ) You just spend an hour with your PM to explain that some feature having some problem and we are unable to release this module in today's beta... after a lot of arguments you are given an hour to make your app work without this module, you sit on your workstation to make a release and all of a sudden you found a silly problem behind that module..... (you solve it and prepare a desired build) did you face miracle (= sudden, positive surprises?) in your life?? what was your reaction in case you have come through such experience?? (N.B. I know my English is not that good and that's why I'm open to every linguistic mistakes needed to be corrected)

• Arguing Developers

  - by Desolate Planet

  My head hurts as I type this question. The reason for this? I've got two developers yelling behind me at the top of their voices while everyone else tries to get some work done. I've worked in three companies so far and I've noticed that developers refuse to make use of meeting rooms and instead feel the need to enter long drawn out conversations where they yell at each other. Any ideas on how to handle this? A "Please be quiet" doesn't seem to have any effect and my head is thumping, so I'll entertain any ideas.

• is OpenID really that bad?

  - by DoPPler

  I have seen this question on Quora where lots of people seem to agree that OpenID is bad, even going as far as stating that: OpenID is the worst possible "solution" I have ever seen in my entire life to a problem that most people don't really have Then I've seen articles and tweets referencing that question saying that OpenID has lost, and Facebook won. It's sad to read as I quite like the OpenID (or at least idea behind it). I literally hate getting yet another login/password for page (I'll forget it anyway) - it's a pretty serious issue for me and I know lots of people with the same problem. Thus I thought that OpenId is a great solution but I'm not sure anymore. So the question is should I still bother to implement OpenID or it's not worth it? What is the most robust and convenient (from the user perspective) way to identify and authenticate an user?

• Is there ongoing work in the kernel team to improve battery life under linux?

  - by leousa

  I have read in some forums that the kernel team is working on improving battery life and energy efficiency in linux. Unfortunately our community really lags behind windows and mac in that regard. I would like to read about the reasons why this difference exists with other platforms. Is it purely due to closed hardware specs from vendors or does it has to be with kernel design issues? Apple devices with unix cores have amazing battery times, but they also design their own hardware...just want to understand this issues in a less technical way I know that recent kernel updates in Ubuntu have improved the battery life in most computers, but I was wondering if there is still development going on and where can I read more about it. Thanks in advance

• SSRS optional parameters settings

  - by Natasa Gavrilovic

  Recently I had to create couple SQL Server Reports (SSRS) with optional parameters built in. It took me a while to refresh memory how this can be done. It was very simple to create reports and processes behind, but connecting these two were are little bit challenging – stored procedure was tested and worked fine, but when the report was passing optional parameters it didn’t returned expected results. After tweaking SQL stored procedures and reports parameter options, the following approach turn to be the winning one. 1) Defining report parameters: From Menu bar select ‘View’ and ‘Report Data’ Newly open window should have ‘Parameters’ folder display Right click on this folder and select ‘Add new parameter...’                             Default values need to be added from a query                 A query values need to include ‘’ (empty string) – as highlighted                   2) SQL stored procedure should have CASE statements inside WHERE and it was the only way that a report was getting correct results back.

• Is it faster to loop through a Python set of number or a set of letters?

  - by Scott Bartell

  Is it faster to loop through a Python set of numbers or a Python set of letters given that each set is the exact same length and each item within each set is the same length? Why? I would think that there would be a difference because letters have more possible characters [a-zA-Z] than numbers [0-9] and therefor would be more 'random' and likely affect the hashing to some extent. numbers = set([00000,00001,00002,00003,00004,00005, ... 99999]) letters = set(['aaaaa','aaaab','aaaac','aaaad', ... 'aaabZZ']) # this is just an example, it does not actually end here for item in numbers: do_something() for item in letters: do_something() where len(numbers) == len(letters) Update: I am interested in Python's specific hashing algorithm and what happens behind the scenes with this implementation.

• Does an inventory limit in an MMORPG make sense?

  - by Philipp

  I am currently developing a simple 2d MMORPG. My current focus is the inventory system. I am currently wondering if I should implement a limit on what a player character can carry. Either in form of a maximum weight, a limited number of inventory slots, or a combination of both. Almost every MMORPG I ever played limits inventory space. But plausibility aside, is this really necessary from a gameplay point of view? Maybe it would in fact improve the game experience when I just let the players carry as much stuff as they want. tl;dr: What is the game development rationale behind limiting carrying capacity of player characters?

• jQuery sanitizing comments and linkifying URLs

  - by iWasRobbed

  In terms of jQuery (or Javascript), what happens behind the scenes when a person posts a comment on Facebook, Twitter, or a blog? For instance, do they sanitize the text first, and then pattern match URL's into an actual link? Are there other items of concern that the client-side should check in addition to doing some checks on the backend? I have found a few regex's for turning URL's into links, but I'm not sure if there are better solutions. I'm trying to wrap my head around the problem, but I'm having a difficult time knowing where to start. Any guidance you can provide is greatly appreciated!

• How to change time servers in 11.10

  - by Reinis I.

  I'm behind NAT, so I can't access pool.ntp.org or Ubuntu's own time servers directly, and I'd like to change the time servers for my system. When googling, I find references to missing manpages like ntpd.conf(5) and ntpd(8), to a missing GUI for setting the time servers, and to a cron script (/etc/cron.daily/ntpdate) that doesn't seem to exist on my system. I've also found a reference to there being changes to ntpd.conf, so I'm hesitant to just create that file in /etc. How is one supposed to change the time servers in 11.10?

• Question About Eclipse Java Debugger Conditional Breakpoints Inefficiency

  - by Personman

  I just set a conditional breakpoint in Eclipse's debugger with a mildly inefficient condition by breakpoint standards - checking whether a HashMap's value list (8 elements) contains Double.NaN. This resulted in an extremely noticeable slowdown in performance - after about five minutes, I gave up. Then I copy pasted the condition into an if statement at the exact same line, put a noop in the if, and set a normal breakpoint there. That breakpoint was reached in the expected 20-30 seconds. Is there something special that conditional breakpoints do that is different from this, or is Eclipse's implementation just kinda stupid? It seems like they could fairly easily just do exactly the same thing behind the scenes.

• Are "backwards" terminators for if and case unique to shell scripting?

  - by tomjakubowski

  In bash at least, if and case blocks are closed like this: if some-expr then echo "hello world" fi case $some-var in [1-5]) do-a-thing ;; *) do-another-thing esac as opposed to the more typical close of end or endif/endcase. As far as I know, this rather funny convention is unique to shell scripting and I have never seen such an odd block terminator anywhere else. Sometimes things like this have an origin in another language (like Ruby's elsif coming from Perl), or a strange justification. Does this feature of shell scripting have a story behind it? Is it found in other languages?

• What's the best way to debug AJAX to PHP calls?

  - by Jascha

  I'm having a miserable time debugging one small function on my new project. Essentially I'm having a user log out via an AJAX call to my log out script on my server called "userfFunctions.php" I'm using AJAX so that I don't have the headache of writing more regex to match my mod_rewrites. Anyway, every so often, it seems as though my Post data just flat out dies and since the PHP is running behind the scenes, I feel like I have no way of finding out where the data flow is being disrupted. BTW This function works 19 hrs of the day. Here is the javascript function: function logOut(){ var data = new Object; data.log_out = true; $.ajax({ type: 'POST', url: 'http://www.mydomain.com/User_Validator', //<-- redirects to userFunctions.php data: data, success: function(data) { alert(data); // <-- a response is triggered but with no response data! } }); } the php side: if(isset($_POST['log_out'])){ echo 'alert this!'; } here is my awesome response:

• What are the advantages of combination WPF + XNA?

  - by MartyIX

  Hi, I'm porting my application from Winforms+XNA to WPF (+ XNA?) and I would like to know if the combination WPF + XNA makes sense or not. If it brings some advantages or if it is rather a bad choice. A few points about my game: It's a desk game with simple 2D animations (movement) Main window contains panels like available games/players etc. + console. I would like to add some fancy scenes to my program (at end of game, ...) http://www.codeproject.com/KB/WPF/XnaInWPF.aspx is the code I would like my program base on. So the appearance is quite similar to a chess program. Thank you for suggestions!
