• Google Earth-Unsupported graphics card

  - by VIPaul

  I've just installed Google Earth on my PC,which runs Ubuntu 12.04 LTS. When I open Google Earth,a window pop-ups and says:"Unsupported Graphics Card Your graphics card does nor meet the minimum spec required to run Google Earth,which is a 3D accelerated card with shader support.It is strongly recommended that you try running Google Earth on a different machine or in a different rendering mode or upgrade to a newer graphics card.You may continue,but the application is unlikely to work." Maybe you'll say:"Buy a better graphics card!",but I used Google Earth on this machine an year ago,when I had Windows 7 & everything worked well,so my graphics card is good enough. The Linux version has bigger requirements than the Windows one or what???

• how to uninstall sphinx server

  - by misterjinx

  I installed (from sources) yesterday sphinx server and didn't think of configuring it properly, so I left the default installation directory (/usr/local). Today I realized that it created all of it's directories inside that directory, instead of creating its own (as I wrongly thought). So today I started again the installation and specified explicitly the location where to install. After that I removed the previous directories from /usr/local that were created when the first installation was done (bin, etc, var). So I thought of giving it a test. I created the .conf file and wanted to run the indexer. But now, the indexer always tries to search the .conf file in the old location (obviously does not find anything) and when I specify where to find the .conf file it gives me errors for each of the configuration settings present. I know I did something wrong when I deleted manually those files and that's why I'm asking you if have any ideas how to correctly uninstall sphinx. Thank you.

• Designing and refactoring of payment logic

  - by jokklan

  Im currently working on an application that helps users to coordinate dinner clubs and all related accounting. (A dinner club is where people in a group, take turns to cook for the rest and then you pay a small amount to participate. This is pretty normal in dorms and colleges where im from). However there is some different models that all have a price and the accounting aspect is therefore a little spread. We both have DinnerClub, ShoppingItem and are about to implement the third Payment when users pay their debts (or get refunded for expenses). Each of these have a "price" attribute and a users expense (that he or she needs refunded) is calculated by the total of these "prices" minus what other users have bought and he or she have used/participated in. My question is then if someone have some hints to refactor this bring all this behavior together in one place? For now have i thought about a Transaction class that are responsible for this behaviour, but I'm a little worried about the performance impact on having to query for another polymorphic record each time i want to show the price on dinner clubs and shopping items (i have a standard index page with a list for both so it's a lot of extra records being queried)...

• Storing data offline with javascript

  - by Walker

  My question is about storing data offline and potentially whether I will need to bring in an outside programmer or could this be learned within a few weeks? The website I am working on will have an interface where users will login and go through a series of quizzes in the form of checkbox, drop down menus, and others. Each page/quiz area could have 20-100 total checkboxes in a series of 3-5 rows because of the comprehensive nature of course. This I can do - I know how to code the quiz and return a correct or incorrect answer based on each individual checkbox and present a cumulative score (ie: you got 57% correct). The issue lies in the fact that I would like to save the users results and keep them informed of their progress. When they complete all of the quizzes, I would like to have a visual output of their performance in each area. Storing the output from their results offline is where I think I may run into a problem with my lack of coding experience. I would also like to have a sidebar with their progress of each section (10-15) with a green percentage completion bar or a % correct which would draw from this. I have never had to code something that stores information like this offline - so back to my question - would it be better to learn the language needed or bring in a coder/developer for the back end stuff.

• Unix tools in business use: are they helpful?

  - by Prometheus

  Do you think knowing Unix tools like sed, awk, LaTeX, Perl give you a great edge in the business world? (e.g. being a manager) From my short reflection, the only profession that needs those sort of (plain text) tools is programming. Because even when I do creative writing, I rarely ever need it. I mean, do CEOs and executives of large corporations ever learn this kind of stuff if they were not CS major to begin with?

• SQL Profiler Through StreamInsight Sample Solution

  In this postI show how you can use StreamInsight to take events coming from SQL Server Profiler in real-time and do some analytics whilst the data is in flight.  Here is the solution for that post.  The download contains Project that reads events from a previously recorded trace file Project that starts a trace and captures events in real-time from a custom trace definition file (Included) It is a very simple solution and could be extended.  Whilst this example traces against SQL Server it would be trivial to change this so it profiles events in Analysis Services.       Enjoy.

• Applying to a company while personally working on a comparable project

  - by Developer Art

  That's going to be an unusual question but here it goes. I'm entertaining the thought to send my docs to a place which develops a large web project of a social type. Social meaning people, communities, interaction and all that usual stuff. The issue is that I myself am working on something that falls into the category of social in my private time. Now the question. Is it wise to apply there under these circumstances? I think there may be issues of intellectual ownership if I develop something similar that exists or will exist in that company's work. On the other hand, the web of full of social places (even this site is one of them), many of them utilize the same ideas and move in the same direction and it seems to work for everyone. It's hard to come up with something which hasn't been tried yet by somebody else so it's all basically reuse of the commonly available ideas and experience. What I'm working on is not a functional equivalent, it's rather largely off. There may be some intersections, but on a large scale this is not an equivalent. And whatever features might coincide, they already exist everywhere on the web anyway. Also technology stacks are entirely different so the issue with directly copying out parts of the code is probably not applicable. I plan to say it up front that I'm engaged in a personal project of mine and let them see if it represents a problem for them. What do you think? Am I making things up or is there really an issue?

• Should a primary key be immutable?

  - by Vincent Malgrat

  A recent question on stackoverflow provoked a discussion about the immutability of primary keys. I had thought that it was a kind of rule that primary keys should be immutable. If there is a chance that some day a primary key would be updated, I thought you should use a surrogate key. However it is not in the SQL standard and some RDBMS' "cascade update" feature allows a primary key to change. So my question is: is it still a bad practice to have a primary key that may change ? What are the cons, if any, of having a mutable primary key ?

• How to search drupal site from the new Unity lense?

  - by Ognjen

  I'm creating a simple Unity lense for my college site which is based on Drupal, but I don't know how to adapt this command for Drupal API. Please help, it's python. We now create our query url, using the Wikipedia opensearch API url = ("%s/w/api.php?action=opensearch&limit=25&format=json&search=%s" % (self.wiki, search)) I'm using template to write lense following Wikipedia example http://developer.ubuntu.com/2012/04/how-to-create-a-wikipedia-unity-lens-for-ubuntu/. I don't know python but Im familiar with C. This Drupal API calling is the only problem I have to successfully develop a lense. Please help!

• Rules of Holes #4 -Do You Have the BIG Picture?

  - by ArnieRowland

  Some folks decry the concept of being in a 'Hole'. For them, there is no such thing as 'Technical Debt', no such thing as maintaining weak and wobbly legacy code, no such thing as bad designs, no such thing as under-skilled or poorly performing co-workers, no such thing as 'fighting fires', or no such thing as management that doesn't share the corporate vision. They just go to work and do their job, keep their head down, and do whatever is required. Mostly. Until the day they are swallowed by the...(read more)

• Is it a must to focus on one specific IT subject to be succesful?

  - by Ahmet Yildirim

  Lately I'm deeply disturbed by the thought that I'm still not devoted to one specific IT subject after so many years of doing it as a hobby. I've been in so many different IT related hobbies since I was 12. I have spent 8 years and now I'm 20 and just finished freshman year at Computer Eng. Just to summarize the variety: 3D Game Dev. and Modelling (Acknex, Irrlicht , OpenGL, GLES, 3DSMAX) Mobile App.Dev (Symbian, Maemo, Android) Electronis (Arduino) Web.Dev. (PHP, MYSQL, Javascript, Jquery, RaphaelJS, Canvas, Flash etc.) Computer Vision (OpenCV) I need to start making money. But I'm having problem to pick the correct IT business to do so. Is it a problem to have interest in so many different IT subjects?(in business world) I'm having a lot of fun by doing all those stuff from time to time. Other than making money I also noticed that having so many different interests is lowering my productivity. But I'm still having difficulty to pick one. I'm feeling close to all those subjects (time to time).

• Is it okay to showcase templates/layouts recreated in different codes in a portfolio?

  - by Souta

  I have several different templates/layouts, both simple and complex. I recreated these templates multiple times, just using different codes. (Say, a complex one was originally made in only HTML and CSS, I recreated it using HTML, Javascript, CSS, then again with a HTML and PHP concoction, and etc.) I wanted to showcase my work and skills by doing this, but I don't know if it would be okay for that all to go into a resumé/portfolio. This is why: Freelancing Does potential business really care about how their site is made, as long as it looks and functions to their liking? (As in, should I just only show the one example of each template/layout and not the multiple recreations?) Potential Hire However, if a potential employer were to stumble across my resumé/portfolio, would having the multiple recreations do any good for a career outlook? (As in, this potential employer is a company where I could be working on a team to create/develop sites and not be freelancing; would a lack of skill-shining turn this employer away because I didn't set myself apart and show that I'm not just like every other budding web designer?) Those two issues have me wondering if it is okay to have a resumé/portfolio combined for this specific reason. Or does something like this not matter to potential business (as a freelancer) because they wouldn't care either way as long as it looks and functions to their liking and therefore it is okay to showcase the recreations with the originals?

• How serious/common are wordpress updating issues

  - by gyaani_guy

  I am currently deciding between a CMS (joomla OR wordpress )to dive deep into. I think I would go for wordpress, but the only thing thats holding me back are any potential issues with updating wordpress- that updating wordpress can break plugins, but is necessary because of security issues. How drastic are the changes in wordpress? say over a period of 2-3 years? from the perspective of someone intending to dive head first in its code. Should I fear regular updates breaking stuff ? Thanks

• Part-time work as a beginner programmer [on hold]

  - by Valentas

  I wrote to one company near my university (starting in September) and they responded that they will probably hire me from the work I have already done (some projects and Euler problems solving). It's for 15 hours/week or so in order to not fall behind uni work. They require Python, SQL, XML and a good idea about how the Web works. The job role involves acquiring data from the Web and supplying it as search results for flight seekers (people). I am eager to learn but still, what can I do to become prepared for this? I ask because I tend to gravitate from one technology to the other, trying out things but never mastering it properly. What Web technologies are involved in such a job role? I have two months and want to learn as much as possible because there is much info but I have no idea where to start.

• GtkFileChooserButton 'Select Folder' mode returns no path

  - by user8592

  I have added a GtkFileChooserButton to my app via Glade. It is set to folder selection mode. When the widget is clicked it shows a dropdown list of Nautilus bookmarks with an 'other' option in the end. A new file chooser dialog is launched when 'other' is clicked. The button is not connected to any other custom file chooser dialog. The connecting signal I am using is 'file-set' and I am retrieving the fullpath of user selected folder using Gtk.FileChooser.get_current_folder (). This setup works fine if user selects a folder from 'other' option. But if a user selects a bookmark from dropdown list, no path is returned. How to solve this? Is there a way to disable this dropdown list and directly go to the filechooser dialog? I want to use GtkFileChooserButton only so that the user can get a preview of his selected folder.

• CIOs: Stop Mandating Training

  - by merrillaldrich

  I love to learn about new technology, and I especially love a long deep-dive technical session with a real expert or a well-crafted, inches thick technical book. Even if either one is expensive. Learning is probably my favorite thing to do. Yet I stand before you with an appeal: Stop “sending people to training.” Why would I say such a thing? Because failure is baked right into that very phrase: “sending people to training.” Death by Training Most of us in the IT world have probably experienced this...(read more)

• How do I pass tests with higher scores? [closed]

  - by user1867842

  How do I pass a test of programming knowledge for a higher score on oDesk.com? I have passed php and javascript tests but I have passed them with low scores and barley passing. This doesn't look too appealing for clients and I'm afraid that is the reason I am not being hired for a job. I know I am capable of doing web work and such. But I haven't been accepted for an interview or anything. Any idea how to study for something like this ?

• Final Year Project Advice: what impact on my CV [closed]

  - by Devon Smith

  I am being offered - as a final year project - to do a Company Website. This is basically an out-house project and I am not completely sure whether I should take it. The requirements are : Company Information User Registration Order placements. The technologies that I should use are PHP, Javascript, HTML, CSS and maybe Java Servlets. This appears to me a very basic project and I need an opinion as to what effect it might have on my CV. Is it worth to do it? Or should I go into some research project or something that has not been done before?

• Education and Career Resources from Microsoft and the Community

  - by KKline

  Sometimes I'm timely in getting the news out on useful resources. And, other times, I'm a bit slower on the draw. As I told my friends back at New Year's Day, "As an official member of the Procrastinators Club, welcome to 2008!" On the other hand, it's always good to remind folks of great resources that are still available and on the shelf. Why? Well, the Internet hits us with such a deluge of constantly new material, that we often forget about the old(ish) stuff that's still really useful. Darth...(read more)

• How can I clone or mirror a site without SEO penalties for duplicate content?

  - by Amanda

  I am a web developer and I want to create clones of the sites I've developed for clients, so that I have an "original copy" on a subdomain of my own website, so that I can showcase my work to new clients. What is the best way to not get my clients original websites penalised for duplicate content? I am planning to have a robots.txt file that disallows all robots, as well as using <link href="http://www.client-canonical-site.com/" rel="canonical" /> in the <head> of the pages. Is that sufficient? Should I use rel=nofollow on all the links as well?

• My application quicklist goes missing when using "quickly submitubuntu"

  - by Kazade

  I'm trying to submit my app for the app showdown, but I've just noticed that when I use the "submitubuntu" Quickly command, my dynamic quicklist entries don't work. I think this is because the desktop file gets renamed from tickit.desktop to extras-tickit.desktop I'm coding a hacky fix to look for /usr/share/applications/extras-tickit.desktop and changing the argument for get_for_desktop_id() if it exists, but is there a better way? Can I stop Quickly renaming the desktop file?

• What are the dos and dont's when leaving a job? [closed]

  - by john ryan

  I'm going to resign from my current employer (manufacturing sector), where I've been working for 2.6 years as an IT Application Developer. It's the first company I've worked in after I graduated from college. I don't have any problem with the company, I just realized that I want to learn new technologies and get out of my comfort zone and move to the IT industry. I already got a job offer from another company. My IT manager has told me that I am one of the best players in our group, that our group is enough to support our company and that it would be unacceptable if anyone of us resigned. They will counter the offer, but I'm set on leaving. My problem is that I don't know what are the essential dos and don'ts when resigning from a current employer. For example I'm expecting a lot of inquiries on why I'm leaving from people in the company, what do I need to say?
