• By what features and qualities are "free" and "premium" themes differentiated

  - by Sinthia V

  I have a lot of time invested in creating Wordpress templates. I want to release combinations of these templates along with different styles and Fancy Front pages as "Premium Wordpress Themes". What I need to know is what does "Premium" mean? What do people expect of a GPL theme vs. a Premium theme? Are there features that are considered required to be premium? Are there features that are in demand but considered "exceptional" i.e. not part of every premium theme? How can I tell the difference? I have heard tounge-in-cheek answers that say that any theme that makes money is premium, but I mean to ask about what gives an outstanding theme it's quality. Why is it worth more? I am technically able to do many things, but as a lone developer with a family to feed, I can't afford to spend time on features that no one cares about. I have to try to isolate the things that people want. This is serious food and rent to me. How can I get this kind of info so I can make my project successful?

• What language available on commodity web hosts would suit a C# developer? [closed]

  - by billpg

  Recognising its ubiquity on commodity web hosting services, I tried developing in PHP a few years ago. I really didn't like it, later deciding that life was too short for PHP. (In brief, having to put $ on variable names; mis-spelt variable names become new variables; converting non-numeric strings to integers without complaint; the need for an "and this time I mean it" comparison operator.) In my ideal world, commodity web hosts would all support C#/ASP.NET, my preferred web-development language and framework, but this is not my ideal world. Even Mono has barely made a dent on Linux based hosts. However, last time I moaned about PHP's ubiquity, someone followed up that this was no longer the case, and that many other languages are now commonly usable on web hosts too. What programming language; a. Would suit a developer who prefers C#. b. Is available to run on many web hosts.

• Web dev/programmer with 4.5 yrs experience. Better for career: self-study or master's degree? [closed]

  - by Anonymous Programmer

  I'm a 28 year-old web developer/programmer with 4.5 years of experience, and I'm looking to jump-start my career. I'm trying to decide between self-study and a 1-year master's program in CS at a top school. I'm currently making 65K in a high cost-of-living area that is NOT a hot spot for technology firms. I code almost exclusively in Ruby/Rails, PHP/CodeIgniter, SQL, and JavaScript. I've slowly gained proficiency with Git. Roughly half the time I am architecting/coding, and half the time I am pounding out HTML/CSS for static brochureware sites. I'd like to make more more money while doing more challenging/interesting work, but I don't know where to start. I have an excellent academic record (math major with many CS credits, 3.9+ GPA), GRE scores, and recommendations, so I am confident that I could be admitted to a great CS master's program. On the other hand, there is the tuition and opportunity cost to consider. I feel like there are a number of practical languages/tools/skills worth knowing that I could teach myself - shell scripting, .NET, Python, Node.js, MongoDB, natural language processing techniques, etc. That said, it's one thing to read about a subject and another thing to have experience with it, which structured coursework provides. So, on to the concrete questions: What programming skills/knowledge should I develop to increase my earning potential and make me competitive for more interesting jobs? Will a master's degree in CS from a top school help me develop the above skills/knowledge, and if so, is it preferable to self-study (possibly for other reasons, e.g., the degree's value as a credential)?

• How to manage Agile developers working with traditional (serial) business persons?

  - by Riggy

  Good afternoon, My work environment has some problems. Our IT team is trying to be more agile, but we're not really getting buy-in from the business. They attend our daily stand-ups and sprint reviews, and they help with sprint planning, but then they turn around and do 4 months of requirements gathering for a project before moving forward with a (mostly) serial development style. The sprint goals are things like "get XX% closer to release". For the IT team, they've turned the Sprints into a sort of death march. We end a Sprint one day and start a new Sprint the very next day. There's no reflection or changes done between sprints, only during. Having never done any of the agile methodologies before, I haven't had a very pleasant introduction to them. So my questions are: 1) Should there be some time (perhaps a week or so) between sprints to do the reflection/introspection/changes/etc.? Or are back-to-back-to-back sprints the norm? 2) Is there any chance for survival for an agile team with no agile business counter-parts? If not, are there some transitional methodologies or even tips for moving the business towards an iterative if not necessarily agile mindset? 3) Should your entire team be on every sprint? We have almost 20 programmers on a single sprint but working on completely different projects (typically teams of 3-5, sometimes larger). Is it normal to have a single sprint or should we be trying to manage multiple independent sprints? Should we be trying to keep the multiple sprints in concurrent lockstep or should their timetables be allowed to overlap and be flexible? Any thoughts or advice is appreciated. This is my first time coming over from SO for a question, so please let me know if there are better ways to phrase these kinds of questions (faq was rather helpful, but still not sure I'm following it perfectly). Thanks!

• Resume on 30 Days of SharePoint

  Dear readers, as you might have noticed... It was an organisational desaster on my end! Even though I continued my studies and research on Microsoft SharePoint 2013 during the last 30 days, I wasn't able to write an article a day to keep you posted on my progress. Nonetheless, I gathered a good number of additional blogs, mainly SharePoint MVP sites, and online forums which will be helpful in the next couple of weeks while I'm actually going to develop a C#-based client which will enable an existing 'legacy' application to SharePoint as a document management system (DMS) besides other already existing solutions. Finding excuses Well, no. Not really. I simply didn't block any or enough time every day to write down my progress during my own challenge. My log book on learning about SharePoint stands at 41 hours and 15 minutes during this month. Which means that I spent an average of more than 1 hour per day on getting into SharePoint. I know that might sound a little bit low but also keep in mind that I went for the challenge on top of my daily job and private responsibilities. During the same period there had been two priority 0 incidents from clients - external root cause - which took presedence over this leisure project. More to come Anyway, it was a first trial and despite the low level of reporting on my blog, I'm confident about what I learned during the last 30 days, and I'm ready to implement the client's requirements. At least, I would say that I have a better understanding about the road map or the path to walk during the next month. As time and secrecy allows I'm going to note down some bits and pieces... During the process of development, I'm going to 'cheat' on the challenge summary article and add links to those new entries. Just for the sake of completeness. Next challenge? Hmm, there had been ideas during the last meetup of the Mauritius Software Craftsmanship Community (MSCC) regarding certifications in IT and eventually we might organise some kind of a study group for specific exams, most probably Microsoft exams towards MCSD Web Developer or Windows Developer.

• Ubuntu 12.10 wont boot

  - by John Mark High

  im new to using Ubuntu and just bought a HP Pavilion g6-2240sa with windows 8 pre installed. I made a bootable USB with Ubuntu on it and installed alsongside windows, for 2 days it worked fine, I got into Ubuntu by doing an advanced restart from windows 8 and then booting Ubuntu from the partition it made. When i did the advanced restart today there was only 1 HDD i could select ( there were 3 before windows, a restore partition that was already there when i got the computer and Ubuntu) so i booted from the USB again and re-installed Ubuntu. then did an advanced restart and the 3 partitions where there again, i booted from Ubuntu and now heres my problem. I get the Ubuntu background when its loading then its just a black screen with some writing, its not on long enough to read, then just a black screen with a white _ and the top left corner that does nothing, i have to restat the computer and it auto boots into windows 8. im a little confused as the first time i installed Ubuntu it worked fine until the partition dissaperd), the second time i installed i did everything the same except it found the old Ubuntu so i reinstalled it and now is donst work.

• I am confused between PHP and ASP.NET to choose as a career in Indian software development context

  - by Confused_Guy

  I need your help(specially from the software professionals of India). I have completed MCA in 2009. After that instead of joining software company I did a Teaching job nearby by home. In the mean time I prepared myself for public sector jobs(bank). I continued my job for 1 year more and left it in 2010. Now in 2012 ,I feel that I should have done the software jobs,so that I could earn my bread and butter and in the mean time I could have prepared for the job.Because,according to my qualification it will give me the best salary. Now I want to go back in software industries. Now all of them are asking for experiences.And I don't have any.....So which language should I learn? And what should I do,because I have two year gap. Some of my friends suggested me to go with PHP as its easier and quicker to get job in India. But Here the PHP guys are getting less salary as compared to ASP.NET. I am planning to begin with PHP and but is it possible to switch to ASP.NET after two years experience. JAVA: I know upto servlet & JSP. Which is nothing in current market. ASP.NET: I know the basics of asp.net upto database connection ie(Gridview). PHP: Only the basics. So what should I do now. Which is most demanding. Does PHP is good, I feel its more like JSP pages. Please guide me, All your suggestions are needed for me.

• Getting error message when trying to start a virtual machine

• Search multiple tables

  - by gilden

  I have developed a web application that is used mainly for archiving all sorts of textual material (documents, references to articles, books, magazines etc.). There can be any given number of archive tables in my system, each with its own schema. The schema can be changed by a moderator through the application (imagine something similar to a really dumbed down version of phpMyAdmin). Users can search for anything from all of the tables. By using FULLTEXT indexes together with substring searching (fields which do not support FULLTEXT indexing) the script inserts the results of a search to a single table and by ordering these results by the similarity measure I can fairly easily return the paginated results. However, this approach has a few problems: substring searching can only count exact results the 50% rule applies to all tables separately and thus, mysql may not return important matches or too naively discards common words. is quite expensive in terms of query numbers and execution time (not an issue right now as there's not a lot of data yet in the tables). normalized data is not even searched for (I have different tables for categories, languages and file attatchments). My planned solution Create a single table having columns similar to id, table_id, row_id, data Every time a new row is created/modified/deleted in any of the data tables this central table also gets updated with the data column containing a concatenation of all the fields in a row. I could then create a single index for Sphinx and use it for doing searches instead. Are there any more efficient solutions or best practises how to approach this? Thanks.

• How to calculate new velocities between resting objects (AABB) after accelerations?

  - by Tiedye

  lately I have been trying to create a 2D platformer engine in C++ with Direct2D. The problem I am currently having is getting objects that are resting against each other to interact correctly after accelerations like gravity have been applied to them. Right now I can detect collisions and respond to them correctly (I think) and when objects collide they remember what other objects they're resting against so objects can be pushed by other objects (note that there is no bounce in any collisions so when objects collide they are guaranteed to become resting until something else happens). Every time the simulation advances, the acceleration for objects is applied to their velocities (for example vx += ax * t, where t is time elapsed since last advancement). After these accelerations are applied, I want to check if any objects that are resting against each other are moving at different speeds than their counterparts (as different objects can have different accelerations) and depending on that difference either unlink the two objects so they are no longer resting, or even out their velocities so they are moving at the same speed once again. I am having trouble creating an algorithm that can do this across many resting objects. Here's a diagram to help explain my problem

• My work isn't being used... what can/ should I do?

  - by Matt

  Several months ago I was approached by a small business, who had seen my work previously and asked me to create a website for them. Since then, the website hasn't changed one bit and I haven't heard a word from them. This sucks for them as they paid for a website and haven't used it. It''s frustrating for me because I spent a huge amount of time on the website and feel that all of that effort has been wasted, furthermore, I don't feel I can use the website on my portfolio/ CV. I was thinking of offering to go round to their office for one day, and update the website for them then and there; but I'd need their support whilst there (to get the content for the about page, to get information for on their products etc.) and I don't want to disrupt their work day, nor do I want to sit there like a spare tyre and get nowhere. Furthermore, if I were to do this, should I expect to receive money for it? It's a day of my life, but I'm doing it for my benefit rather than theirs (but they benefit as well). Has anyone else had experience of a client not using their product; how did you handle it? Additional background for those who want it: The company is a local travel agent, and the website lets them CRUD offers and locations, and has several other static pages (about, contact, etc.) At the time of creating the website, I filled the static pages with lipsum, and the offers and locations with fake information, so that I could give the business an idea about what the final pages would look like; during the hand over, I guided them through the CRUD forms (they made notes) and said if they sent me the text for the pages, I'd update it.

• Creating a steady rhythm for music-based game in XNA

  - by A-Type

  I'm looking to develop a game for Windows Phone to explore an idea I had which involves the user building notes into a sequencer while playing a puzzle game. The issue I'm running into is that, while my implementation is very close to being on-beat, there is the occasional pause between beats which makes the whole thing sound sloppy. I'm just not sure how to get around this inside XNA's infrastructure. Currently I'm running this code in the Update method of my GameBoard: public void Update(GameTime gameTime) { onBeat = IsOnBeat(gameTime); [...] if (onBeat) BeatUpdate(); } private bool IsOnBeat(GameTime gameTime) { beatTime += gameTime.ElapsedGameTime.TotalSeconds; if (Math.Abs(beatTime - beatLength) < 0.0166666) { beatTime -= beatLength; return true; } return false; } private void BeatUpdate() { cursor.BeatUpdate(); board.CursorPass((int)cursor.CursorPosition % Board.GRID_WIDTH); } Update checks to see if the time is on beat, and if it is, it calls the BeatUpdate method which moves the cursor over the board (sequencer). The cursor reports its X position to the board, which then plays any notes which are in that position on the sequencer. Notes are SoundEffectInstances, preloaded and ready to play. Oh, and TargetElapsedTime is set to 166666, or 60FPS target. Obviously totaling up the time and then subtracting isn't the most accurate way to go but I can't figure out a way to work within XNA's system in order to overcome this issue. This current system is just horribly unstable. Beats lag and fire too early and it's obvious. I thought about perhaps some sort of threaded solution but I'm not familiar enough with multithreading to figure out how that would work. Any ideas?

• An online version of ClearTrace

  - by Bill Graziano

  When I visit clients for the first time and conduct a performance review I introduce them to ClearTrace. It’s still the best way I know to identify exactly which queries are consuming the most resources.  The downside is that it needs to be downloaded and create a database to store the results.  I finally decided it would be easier if I could just upload a trace immediately. You can find the online version of ClearTrace at TraceTune.com.  It provides a simple way to upload a trace file and see exactly which stored procedures or SQL statements consume the most CPU and disk.   This is still a work in progress as I try to determine exactly which features from ClearTrace are important.  I’ve also limited the file upload to 10MB in this beta release.  That might not sound like much but I get over 20,000 events using this stored procedure to generate the trace. If you’re looking for something to do on a Friday, I’d suggest a little performance tuning.  Generating 10MB of trace data doesn’t take long at all and in a short time you’ll see exactly which SQL statements you need to tune first.

• Touchpad and Keyboard both stop working after long uptime

  - by Sepero

  I have an Asus N53SM laptop that I leave running for several weeks at a time. I never put it in hibernate or suspend, I only close the lid when I'm not using it. After a few days or weeks of running, the touchpad and keyboard will Both lock up (at the same time) for no apparent reason. I could be just surfing the internet when it happens. The touchpad and keyboard seem to only lock up when I'm actively using the laptop (not when idle), which may mean it's related to something I press, but I'm not sure? The touchpad never locks or unlocks when Pressing FN and the designated touchpad lock key (it does not seem to work on Linux). While the touchpad and keyboard are locked, I am able to plug in my USB mouse and successfully use it to control the screen cursor. I can also remotely get into the system with vnc and ssh, everything seems to run fine there as well. No processes appear out of control. It's just the laptops physical touchpad and keyboard that are locking up. How might I go about diagnosing this problem? What system logs to look at? (anything specific to look for in them?) Perhaps I should try reloading some modules? Any thing else I should inspect?

• What is a good way to refactor a large, terribly written code base by myself? [closed]

  - by AgentKC

  Possible Duplicate: Techniques to re-factor garbage and maintain sanity? I have a fairly large PHP code base that I have been writing for the past 3 years. The problem is, I wrote this code when I was a terrible programmer and now it's tens of thousands of lines of conditionals and random MySQL queries everywhere. As you can imagine, there are a ton of bugs and they are extremely hard to find and fix. So I would like a good method to refactor this code so that it is much more manageable. The source code is quite bad; I did not even use classes or functions when I originally wrote it. At this point, I am considering rewriting the whole thing. I am the only developer and my time is pretty limited. I would like to get this done as quickly as possible, so I can get back to writing new features. Since rewriting the code would take a long time, I am looking for some methods that I can use to clean up the code as quickly as possible without leaving more bad architecture that will come back to haunt me later. So this is the basic question: What is a good way for a single developer to take a fairly large code base that has no architecture and refactor it into something with reasonable architecture that is not a nightmare to maintain and expand?

• Blog Rebranding

  I have been spending more and more time on learning as much as I can on Agile Development and also have been fairly immersed in rolling out TFS 2010 in our environment.  I feel like it is time to talk about some of my experiences.  With that, I am rebranding my blog to focus on these topics.  I am going to start with a bunch of blogs on the process I have gone through getting TFS 2010 configured for our development teams. Last week, Brian Harry was in our office and gave a great talk on the improved tools in TFS 2010 and how Microsoft uses the tools internally.  I followed that up with a high-level overview of the improved out of the box process templates and the process to customize them.  I am definitely very excited about the new features in 2010 and hopefully will keep up my motivation to blog about it.  I am writing my first post right now about the process I went through to build a task progress report based on the user story progress report in the MSF for Agile Development template.  Stay tunedDid you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• How can I make my PHP development environment more efficient?

  - by pixel

  I want to start a home-brew pet project in PHP. I've spent some time in my life developing in PHP and I've always felt it was hard to organize the development environment efficiently. In my previous PHP work, I've used a windows desktop machine and a linux server for development. This configuration had it's advantages: it's easy to configure Apache (and it's modules)/PHP/MySql on a linux box, and, at the time, this configuration was the same like on production server. However, I never successfully set up a debug connection between my Eclipse install and X-debug on server. Transferring files from my local workspace to the server was also very annoying (either ftp or Bazaar script moving files from repository to web root). For my new setup, I'm considering installing everything on my local machine. I'm afraid that it will slow down workstation performance (LAMP + Eclipse), and that compatibility problems will kick-in. What would you recommend? Should I develop using two separate machines? On one? Do you have experience using one of above configurations in your work?

• OpenXML error “file is corrupt and cannot be opened.”

  - by nmgomes

  From time to time I ear some people saying their new web application supports data export to Excel format. So far so good … but they don’t tell the all story … in fact almost all the times what is happening is they are exporting data to a Comma-Separated file or simply exporting GridView rendered HTML to an xls file. Ok … it works but it’s not something I would be proud of. So … yesterday I decided to take a look at the Office Open XML File Formats Specification (Microsoft Office 2007+ format) based on well-known technologies: ZIP and XML. I start by installing Open XML SDK 2.0 for Microsoft Office and playing with some samples. Then I decided to try it on a more complex web application and the “file is corrupt and cannot be opened.” message start happening. Google show us that many people suffer from the same and it seems there are many reasons that can trigger this message. Some are related to the process itself, others with encodings or even styling. Well, none solved my problem and I had to dig … well not that much, I simply change the output file extension to zip and extract the zip content. Then I did the same to the output file from my first sample, compare both zip contents with SourceGear DiffMerge and found that my problem was Culture related. Yes, my complex application sets the Thread.CurrentThread.CurrentCulture  to a non-English culture. For sample purposes I was simply using the ToString method to convert numbers and dates to a string representation but forgot that XML is culture invariant and thus using a decimal separator other than “.” will result in a deserialization problem. I solve the “file is corrupt and cannot be opened.” by using Convert.ToString(object, CultureInfo.InvariantCulture) method instead of the ToString method. Hope this can help someone.

• How to optimize a box2d simulation in action game?

  - by nathan

  I'm working on an action game and i use box2d for physics. The game use a tiled map. I have different types of body: Static ones used for tiles Dynamic ones for player and enemies Actually i tested my game with ~150 bodies and i have a 60fps constantly on my computer but not on my mobile (android). The FPS drop as the number of body increase. After having profiled the android application, i saw that the World.step took around 8ms in CPU time to execute. Here are few things to note: Not all the world is visible on screen, i use a scrolling system Enemies are constantly moving toward the player so there is alaways to force applied to their body Enemies need to collide between each others Enemies collide with tiles I also now that i can active/desactive or sleep/awake bodies. Considering the fact that only a part of the enemies are possibly displayed on screen, is there any optimizations i can do to reduce the execution time of box2d simulation? I found a guy trying an optimization based on distance of enemies from the player (link). But i seems like he just desactives far bodies (in my case, i could desactive bodies that are not visible). But my enemies need to move even when they are not visible on screen, and applying forces will not workd on inactive bodies. Should i play with sleeping bodies here? Also, enemies are composed by two fixtures and are constantly colliding with each others and with tiles but i really never need to get notified about that. Is there anything i can do to optimize this kind of scenario? Finally, am i wrong to try to run simulation at 60FPS on mobile and should i try to make it run at 30FPS?

• Incomplete Ubuntu 12.04 install dual-boot XP

  - by Mike

  This weekend has been the 1st time I've tried to install Ubuntu. On the initial install, (I am using a USB) the installation went all the way through and asked to restart when completed. I was not able to get grub to boot and kept going through Windows. After some research I found some articles on updating/reinstalling grub, so I followed those. I finally got grub to load after a day but there was no Windows option only the Ubuntu 12.04 which when I selected it only gave me a fatal error 17. I booted from the USB again and deleted the partitions and installed again. This time I got an error 15. I then booted through XP and downloaded the WUBI.exe and uninstalled Ubuntu and reinstalled again. The installation went to the very end and then gave an error message (which I don't remember exactly what it said) something along the lines of checking my logs on my C drive. I then uninstalled Ubuntu and removed the wubi.exe file and wiped my USB and did the download to the USB again. Booted through USB and ran the install process again. It again went through the install process but after creating username and password and hitting continue, the installation dialogue box disappears and the mouse spinning wheel is displayed, but I do not receive the prompt to restart. I can still access the side menu for Ubuntu but the wheel keeps spinning. How do I get Ubuntu to install properly?

• 11.10 system crashes for no apparent reason [closed]

  - by varanoid

  I'm relatively new to Linux, and while I know a fair amount about computers and programming, it certainly isn't my specialty. I have a dual boot with Windows 7, and it has been working very well for me until recently. Just randomly the computer will freeze. The last time I was smart enough to keep the System Monitor open when it happened, and it looks like at the time of freezing "bash" and a bunch of other processes that I don't recognize seem to have flooded the memory. So it looks like my memory is getting overloaded and this is what is crashing the system, but I honestly have no idea what could be doing it. Generally I have a bunch of programs running, but they don't take much RAM or CPU: Transmission, Libre Office Writer, Firefox, Empathy, and Banshee. Sometimes I also have Text Editor and Terminal open, but it crashes regardless. When it crashes, it seems that all of the programs are working fine but things like windows, the taskbar, and operations like Alt+Tab just stop working properly or at all. Sometimes the mouse and keyboard freeze and I have to power off manually. Other than that I don't know what the problem is. The only irregularity I've experienced is that I can't download "Debian package management system" even though other updates download fine.

• How do I prevent software packages from being downloaded until I know it's safe?

  - by Dave M G

  Recently, an update that caused a problem with Gnome session caused me to lose a day's work. The solution was to rollback some packages to a previous version. The update manager is now telling me that my old packages should be updated: ... but I don't want to do that until I know that whatever bug or problem the latest version has is resolved. I understand that with any upgrade that there is a risk of instability. However, in the 8 years or more that I've been on Ubuntu, using the latest releases has been stable enough and with the benefit of the latest features and security. So, I'm not looking for general advice on how to handle upgrades. What I'm saying is that in this one particular instance, the bug introduced by these upgrades is severe and time wasting. But, as an end user, when I encounter a problem like this, I have no idea how to address a specific concern about a specific package. I don't, for example, know which of these packages is the problem, and I can't take time from my work schedule to be experimenting with each package. So, my question is: How do I find out who exactly is responsible for these, or any, packages so that I can contact them and let them know about the problem? How do I freeze these packages only, but allow other upgrades to happen? ubuntu-session gnome-session-common gnome-session-bin gnome-session
