• Seizing The Moment With Mobility

  - by Scott Ewart

  Mobile devices are forcing a paradigm shift in the workplace – they’re changing the way businesses can do business and the type of cultures they can nurture. As our customers talk about their mobile needs, we hear them saying they want instant-on access to enterprise data so workers can be more effective at their jobs anywhere, anytime. They also are interested in being more cost effective from an IT point of view. The mobile revolution – with the idea of BYOD (bring your own device) – has added an interesting dynamic because previously IT was driving the employee device strategy and ecosystem. That's been turned on its head with the consumerization of IT. Now employees are figuring out how to use their personal devices for work purposes and IT has to figure out how to adapt.

• What are good ways to find collaborators for a coding weekend?

  - by tarrasch

  Not sure if this belongs here, feel free to push it somewhere else if needed. When i was at university we would sometimes come together into a room full of beer and fast food and crank out software in a weekend. Unfortunately the group has kind of split up and its just not possible any more. My question is now: Where can i find like-minded people on the Internet that would like to do something like this? I have an idea what i wanted to do next, but of course other people have ideas too.

• Snooker Android Application [closed]

  - by Rzarect

  I am working currently on my final year project / dissertation for the university and I have a "crazy" idea for it. I was thinking of designing an android app for Snooker players, different bars or tournaments, an app that will use the mobile camera to detect every movement and change on the table and in the same time will keep the score for the players without any human input. I want to know if it is an impossible thing. If it is plausible I really need some ideas, advices from where to start. I got to say that I have some experience in Android development and I already started to read a lot of articles, projects about the shape detection, color detection and edge detection.

• memory and time intensive php task

  - by Goddard

  Sorry if this question has been asked before, but I couldn't find anything usable. I'm working on a project for a client and currently I have to loop through the users table which is about 3000 records and still growing. I have to do some calculations on a nightly basis which I am going to be using cron/php. The calculations script uses about 3.5mb of memory and takes about 1 second to run. When loading individual users my current php setup handles this fine, but if I try and loop through the user list my php script execution time runs out. I've read after doing some searching that I can make the page reload itself after each user calculation and just keep my previous place in the loop and this sounds like a good idea, but I wanted to hear some opinions from others that have handled similar situations and how you handled these types of tasks. Thanks.

• Why do I get the message "program not found" when running "mal" for Latex

  - by maclin

  just started using Ubuntu (11.10 oneiric). It is running on a virtual machine. I used to use SuSE. However, SuSE is now with Novel, which goes hand in hand with Microsoft. So now shifted to Ubuntu. For documentation I use LaTeX and installed a package. This package uses a pre-processer (it is called "mal"). I ran the textconfig rehash command as required, but when I try to run the program, I get a "program not found" error. I am guessing that it is not in my path. (a sudo did not help) Any idea?

• How should I write new code when the old codebase and the environment uses lots of globals in PHP

  - by Nicola Peluchetti

  I'm working in the Wordpress environment which itself heavily relies on globals and the codebase I'm maintaining introduces some more. I want this to change and so I'm trying to think how should I handle this. For the globals our code has introduced I think I will set them as dependencies in the constructor or in getter / setter so that I don't rely on them being globals and then refactor the old codebase little by little so that we have no globals. With Wordpress globals I was thinking to wrap all WP globals inside a Wrapper class and hide them in there. Like this class WpGlobals { public static function getDb() { global $wpdb; return $wpdb; } } Would this be of any help? The idea is that I centralize all globals in one class and do not scatter them through the code, so that if Wordpress kills one of them I need to modify code only in one place. What would you do?

• Should I learn GWT (I'm a Java newb) if I eventually want to learn JavaScript and related libraries?

  - by Aaron

  I haven't been working with Java for a long time, and I found GWT to be interesting plus a chance to learn and practice Java. My goal for this year is to learn JavaScript. I'm very interested in HTML5, browser extensions and other cool stuff that JavaScript can do. I think I'm more interested in this than Java at the moment (that's not to say I dislike or would discontinue working with Java) but I would like advice as to whether it's a good idea to proceed with learning GWT (given my interest in JavaScript) or to spend my time learning other Java technology. Thank you.

• Why to let / not let developers test their own work

  - by pyvi

  I want to gather some arguments as to why letting a developer testing his/her own work as the last step before the product goes into production is a bad idea, because unfortunately, my place of work sometimes does this (the last time this came up, the argument boiled down to most people being too busy with other things and not having the time to get another person familiar with that part of the program - it's very specialised software). There are test plans in this case (though not always), but I am very much in favor of making a person who didn't make the changes that are tested actually doing the final testing. So I am asking if you could provide me with a good and solid list of arguments I can bring up the next time this is discussed. Or to provide counter-arguments, in case you think this is perfectly fine especially when there are formal test cases to test.

• In what order do people build websites?

  - by Corey

  For a website, you need to have an idea, you need to have a design and you need to have data, events and output, right? Whether it be a blog, web app, Q&A site, search engine... Anyway, that is only slightly related to my question. My question is, when designing a website, providing I know the purpose, what should I start with? Should I start with the CSS, design and look&feel using dummy data first, or should I program in the logic, events and output, and style it later? What is the design process of most websites that are built from the ground up?

• What is the most complicated data structure you have used in a practical situation?

  - by Fanatic23

  The germ for this question came up from a discussion I was having with couple of fellow developers from the industry. Turns out that in a lot of places project managers are wary about complex data structures, and generally insist on whatever exists out-of-the-box from standard library/packages. The general idea seems to be like use a combination of whats already available unless performance is seriously impeded. This helps keeping the code base simple, which to the non-diplomatic would mean "we have high attrition, and newer ones we hire may not be that good". So no bloom filter or skip-lists or splay trees for you CS junkies. So here's the question (again): Whats the most complicated data structure you did or used in office? Helps get a sense of how good/sophisticated real world software are.

• Does anyone have a good example/sample of "goto" spaghetti code? [closed]

  - by ArtB

  I've read a lot about how GoTo was considered harmful and removed for other control structures that were more intuitive. Does anyone have a good example / sample of goto spaghetti code? Preferrably, the sample code should be difficult to follow, but realtively easy when rewritten into more conventional control structures. I know I could try to write you some of my own, but I've never really used goto and don't think I could due justice to the headaches its abuse can lead to. I want this for didactic purposes to train junior developers on what to avoid. Mainly, to point to illustrate how OOP is taking the same idea to next logical consequence. EDIT: by good example I mean code that is terrible to read and abuses it, rather than code that uses goto for reasonable optimization

• How i can sign and/or group a specific set of vertices in a 3D file container like OBJ ? - in Blender

  - by user827992

  I would like to export a 3D model with each part having a name or a label if you will. For example i would like to export a model of an human body and name each part in specifics vertex groups like: left hand, right hand, right foot, head, ears, ... and you got the idea; so i can have a single 3D model that i can explode in various parts if needed. If there is a better technique about how to mark vertex groups in a 3D file please share your solution. As 3D editor i use Blender.

• Install vim offline

  - by rosemary

  I have Ubuntu 12.04.02 desktop in my college Lab of around 15 pcs with no internet connection. I used to install packages : sudo apt-get install vim It was just fine. But, now I want to install vim locally(i.e.,using a pendrive or CD drive). Where and how can I accomplish this,as I am new to it. Through googling, I could get some sites offering packages, but I have merely any idea on how to carry on: https://launchpad.net/ubuntu/precise/+source/vim http://www.ubuntuupdates.org/package/core/precise/main/base/vim http://pkgs.org/ubuntu-12.04/ubuntu-main-i386/vim-gnome_7.3.429-2ubuntu2_i386.deb.html What should I exactly download and where to store it in my ubuntu machine and run commands to properly install vim offline? Any word of advice is appreciated!

• Images from remote source - is it possible or is it bad practice?

  - by user1620696

  I'm building a management system for websites and I had an idea related to image galleries. I'm not sure it's a good approach. Since image space needed is related to how many images a user might upload, I thought about using cloud services like DropBox, Mega, and Google Drive to store images and load then when needed. The obvious problem with this approach is that downloading the images from the 3rd party service would hamper the user experience due to the increased download times. Is there any way to save images belonging in an image gallery on remote source without hampering the user experience because of speed? Or is this approach really not a good practice?

• RewriteRule working local but not on remote server

  - by m0tv

  I have a .htaccess file with one simple RewriteRule: RewriteEngine on RewriteRule ^([A-Za-z0-9-]+)$ ?site=$1 I want to have an url like http://www.example.com/imprint and forward it to http://www.example.com/?site=imprint I checked this rule with an RewriteRule tester which gave me the results I want to achieve. On my local development system it works well too. But on a remote server the URLs just give me a 404 error. Other more simple rewrite rules are working with no problems, so everything must be set up correctly (I think..). The problem is that I don't have access to any error logs or the server configs. So the only thing I can do is to guess... Can anyone tell me if theres something wrong with this rule? Or anything else I can do or test to solve this? Or has someone an idea what could be wrong on the server?

• 2D game big background images for maps

  - by WhiteCat

  Update: this question is general, not specific to Sprite Kit or a single language/platform. I'm toying with Sprite Kit with an idea to make a 2D side-scroller. Now the backgrounds for the maps are going to be hand-drawn and surely bigger than retina display, so the maps could span more than 1 screen in both axis. I imagine loading such a huge image could mean trouble and I don't plan to use tiling. I'm not sure how Sprite Kit splits images bigger than max texture size, if it does. I could split the images myself and use more sprites for each part of the background. What is the usual way to handle this?

• Microsoft Access 2010: How to Add, Edit, and Delete Data in Tables

  Tables are such an integral part of databases and corresponding tasks in Access 2010 because they act as the centers that hold all the data. They may be basic in format, but their role is undeniably important. So, to get you up to speed on working with tables, let's begin adding, editing, and deleting data. These are very standard tasks that you will need to employ from time to time, so it is a good idea to start learning how to execute them now. As is sometimes the case with our tutorials, we will be working with a specific sample. To learn the tasks, read over the tutorial and then apply...

• Can I host a high traffic website at home?

  - by eric01

  I've been searching this up on google but I can't formulate my google search with the right terms to find an accurate answer to my question. Is it possible to have a super-fast connection at home to host a high traffic website? What is the generic term for that kind of connection? What's the major drawback of hosting at home? (I have no idea of the price range but it's probably quite expensive) Do you have to be a company to have the right to own such a connection?

• Can someone help me remove/fix ubuntu?

  - by user286152

  I'm very new to ubuntu for starters. Whenever I turn my computer on, it opens to the GNU Grub terminal. It says it supports minimal Bash-Like line editing (I have no idea what this means). To work-around this, I used "exit -ubuntu", this then takes me to a separate page which I selected the Windows Boot Manager and click on the Windows 8.1 icon which makes my Windows 8 load normally. If I click on the other icon, being the ubuntu one, I get put back at the GNU Grub terminal and thats it. If someone could help me either remove ubuntu or repair it so that I can load it again, I would appreciate it. I had installed the most recent ubuntu version. Any other required information to assist I can provide. Thank you.

• aticonfig detects all graphics cards, but amdcccle shows the cards as disabled

  - by DevZer0

  I been having the strangest problem since few days ago. I have 3 ATI graphics cards and the aticonfig --list-adapter shows the following output * 0. 01:00.0 AMD Radeon HD 7900 Series 1. 02:00.0 AMD Radeon HD 7900 Series 2. 05:00.0 AMD Radeon HD 7900 Series when i do aticonfig --adapter=all --initial -f it generates the correct X config also. but after rebooting the output only show on primary monitor and when i look in amdcccle it shows the other 2 adapters as disabled. I tried with monitors attached and dummy plugs both but the situation doesn't change. Any idea whats causing this? also right clicking and making the adapter enabled in amdcccle and saving changes causes the X config to only have the adapter section and no screen section. after reboot the situation stays the same.

• How can be data oriented programming applied for GUI system?

  - by Miro

  I've just learned basics of Data oriented programming design, but I'm not very familiar with that yet. I've also read Pitfalls of Object Oriented Programming GCAP 09. It seems that data oriented programming is much better idea for games, than OOP. I'm just creating my own GUI system and it's completely OOP. I'm thinking if is data oriented programming design applicable for structured things like GUI. The main problem I see is that every type widget has different data, so I can hardly group them into arrays. Also every type of widget renders differently so I still need to call virtual functions.

• Which language to learn C# or Salesforce.com/apex for C++ programmer [closed]

  - by polapts

  Being a C++ programmer with 7-8 years of experience, I wanted to know the market trends. When I searched a little bit I found more jobs with keyword C# than C++ or Java. I am just wondering if it is a good idea to learn C# or Java from a career perspective. Also, I read somewhere about Salesforce/apex. It was mentioned that this is something in vogue. So my question is which technology I should go for C#/Java/Salesforce(Apex) from career perspective? Thanks

But since i've no ubuntu installed, neither have i any partition that ubuntu should consider like that... How can i go through that?
