• How Effective Websites Are

  It's normal for just about any business or enterprise to have an online business, as well as offices and a shop front. In today's world where individuals increasingly browse the world wide web first for info, it becomes important to take care of and enhance that online presence, as it actually could make or break the traffic to an online site or even the office door. Hiring an SEO agency or guide may seem like a major decision, but the quicker you come to a decision to go for it, the better, especially if you are about to change your present website design or intending to start a fresh one.

• Mulitple processes aware of each other

  - by Abhan

  Hope you can help me with this, I've searched a lot and I got really confused of what to do here. I'm building a program in C and I need to run it multiple time as I need. So it's going to be like below, process 1 handle all rows on DB table test where process_flag=1 process 2 handle all rows on DB table test where process_flag=2 process 3 handle all rows on DB table test where process_flag=3 and so on How can I make the processes aware of each other, so if process 3 goes down then processes 2 & 3 start working on process_flag=3?

• Dynamic Post-build event in Visual Studio

  - by SSumner

  I am building a video server application that has multiple projects in Visual Studio. One project, the video server project, needs to call a shell script to generate documentation. This works fine when you build the video server project, because the script is simply cd "$(SolutionDir)" start documentationgenerator However, there is also an SDK project that, when built, also builds the video server project. However, when it does this, it does not know where the shell script is, since it tries to use the SDK Project's Solution Directory. SDK Project Video Server Project shell script So the question is: how do I make the SDK Project find the Video Server Project? I checked the MSBuild properties and there are no properties that seem to deal with 'nested' projects.

• Ubuntu thinks I have two displays

  - by ResidentBiscuit

  When I first installed Ubuntu I noticed that my mouse would flicker a lot, which caused me to investigate. I remembered back when I ran Fedora I had an issue where it thought I had two displays (hp-dv7 4285dx laptop). In Fedora, this didn't cause any issues. In Ubuntu, it causes the mouse the flicker a lot. The fix I've been using is to just go into settings displays and disable the display that doesn't actually exist. The only problem is that this is not permanent. Each time I start up Ubuntu, I have to go back in and disable this display. They're each just titled "Built-in Display", and have the same resolution. My laptop does have two graphics cards: one on-board and one dedicated. I'm not sure if maybe that is causing is an issue? Any guidance towards this would be great. Thanks!

• Beginner help: where to begin [closed]

  - by shad

  I want to learn how to program. A main stream programming language such as Java, C++/C# is my primary target. Currently, I am a high school student planning to take programming, Digital electronics courses next semester. My biggest problem is that I do not know where to start and I have no one to consult with. Should I take a course at my local community college this summer? Get some books or try learning from some internet websites? What would be the best option a book or website? note that this is no longer my words, but rather ChrisF's because he decided to reword the question a bit (bad) and spaced it out better (good).

• Recommended Linux distro to boot into RAM (from USB flash drive)?

  - by user91583

  I don't mind if I use USB flash drive or CD-ROM, but I would prefer USB flash drive. I had a squizz at http://en.wikipedia.org/wiki/List_of_Linux_distributions_that_run_from_RAM On my own computer, I would be able to use any of the distros in the list. The largest "RAM required" in the list is 4GB. I would like to be able to use it on any computer, so I suppose 1GB or less would be better. I tried to follow the method described on Distro that I can load into RAM? but the distro listed there, from Israel Remix Team, doesn't seem to be available. Before I start trial-and-error on different distros, does anyone have any recommendations?

• Is there a legit reason as to why Outlook.com premium UI is "not available" in Linux Chrome?

  - by vgaldikas

  Well if you use outlook OWA in Chrome on Ubuntu (or any Linux distro), you will get a stripped down version of it basically. You can get around it by faking your user agent, to appear that you are using FireFox. So my question is.. Is there some legitimate reason Microsoft does that, or are they just being a****s??? I mean once you have the user agent faked, it works perfectly. PS. Just in case anyone else need to use outlook, here is the command to start it with fake useragent: /opt/google/chrome/google-chrome --user-agent="Mozilla/5.0 (Windows; U; Windows NT 5.2; en-US) AppleWebKit/534.4 (KHTML, like Gecko) Chrome/6.0.481.0 Safari/534.4"

• How do I recover when Compiz crashes?

  - by winchendonsprings

  Often compiz will crash and leave the keyboard useless. Normally I drop to the console and restart GDM.

(If you have a tip on how to prevent Compiz from crashing I've posted here Fresh install of 11.04x64 - display(compiz) constantly failing ??? - Am I right that Compiz is failing or is it X?

  When I try to log in on my Ubuntu 12.04 it goes to a black screen ( of logging in checking stuff ), and says Checking battery ----- [ok] ( I'm using a computer instead of a laptop ) and just goes back to the login screen.

A big problem is that I don't have internet connection at home. What should I do?

• Can Agile/Scrum be used by 1 or 2 developers?

  - by Dillie-O

  Everything I've been reading and researching up to this point describes how Agile/Scrum works great with teams of about 4 to 6 members, maybe even more. In my current shop, we have about 8 developers or so, but given the nature of the volume of projects and the number of departments we support, we never have more than 1 or 2 folks assigned to a given project. Can I still use Agile/Scrum with a team of 1 or 2 developers? I'm working on making the pitch to my manager to start working with this methodology, but I need to be able to explain how to scale things back for a small developer crew, or convince them to make sure we get more members on a given project.

• Browser game in JSP? [closed]

  - by Constant

  I want to develop a browser-game (like ogame, travian) and I have some doubts in which technologies should I use. I was thinking in a server-side in JSP,Java and a client-side in HTML (or HTML5 if I learn to give it good use). Do you think my choices are right? I would like to make a board where many players could move simultaneously between tiles or squares. Do you think is possible in JSP or I should start with other language? Any suggestion aprecciated, and apologies for my english. Thank you! Regards!

• Failed Vista/Ubuntu 12.04 attempt at dual boot. Can only boot Ubuntu now

  - by mathematician1975

  I recently tried installing Ubuntu 12.04 alongside my Windows Vista install. I can boot fine into Ubuntu every time, but now every time I choose to boot into Windows, the process fails completely and restarts (or shuts down) my laptop. Is there anything I can do to recover this. I am very happy with Ubuntu and I do not want to recover my old Vista installation to overwrite it, but I do need to be able to use both OS's. Is it recoverable or should I start from scratch?

• Coding with laptop and external screen - neck, back, comfort ...

  - by Xorty

  Guess I'm not the only one here coding on laptop + external keyboard + external screen. I can't really decide. Figure 1: Putting screen directly in front of (upright) my eyes and move laptop to the side. That feels like more comfortable but I can't really see so good to 15" laptop which is now quite away. Feels unused. Figure 2: Putting laptop in front of me and move external monitor on side. Feels like more efficient space usage, but I am afraid that my neck/back might start hurting since I need to turn my head often. What do you prefer? Some good advice? Sacrificing health is definitely no option here so that's why I'm worried and asking this silly question. Thanks

• Is it worth becoming a programmer?

  - by D. Higueras

  Hi everybody. I'm a first year student in CS and I absolutely love programming. Many people have told me it isn't so good once you start working. Some things like bringing your work home(thinking about how to solve problems), working many hours when the timeline reaches an end an so on. I've heard being a system administrator is a lot less stressing job, since you don't have to worry about it at home. So my questions are(for experienced programmers): Is it worth becoming a programmer? Does your job satisfy you enough to overcome these problems? Thanks in advance.

• New "How do I ..." series

  - by Maria Colgan

  Over the last year or so the Optimizer development team has presented at a number of conferences and we got a lot of questions that start with "How do I ...". Where people were looking for a specific command or set of steps to fix a problem they had encountered. So we thought it would be a good idea to create a series of small posts that deal with these "How do I" question directly. We will use a simple example each time, that shows exactly what commands and procedures should be used to address a given problem. If you have an interesting "How do I .." question you would like to see us answer on the blog please email me and we will do our best to answer them! Watch out for the first post in this series which addresses the problem of "How do I deal with a third party application that has embedded hints that result in a sub-optimal execution plan in my environment?"

• Number of iterations to real time

  - by Ivansek

  I have an animation of traffic. I have 20 cars in road network, each car have a starting node and end node. Each car know how much distance does it need to travel in order to reach the end node. I move cars each 20 ms for 10 px. To move all cars from their start node to end node I need 60 iterations. That is 60*20ms = 1200ms. Now I want to convert this time, or use data that I have, to a real time where car move 50km/h. How can I do that? Any idea?

• Preparing to release code as open-source

  - by Raphael

  I have developed a fully functional tool which I would like not only to share with anyone interested but also get support from the community. This tool is cross-platform, written in C++ with Qt, the code is well commented but I still lack any documentation. There are also some small issues and improvements to be made before I can call it a stable, final version. What are the first steps that I have to take to release code as open-source and attracting people interested in contributing? This is my first serious attempt to release open-source code and I really don't know where to start. Should I just push it to Github put together a small wiki and pray for the best?

• (Not) Making a Splash with Visual Studio

  - by StuartBrierley

  This post is just a quicky to remind me of a Visual Studio switch that I found interesting/useful. If you are interested in such things, there are a number of command line switches that can be used with Visual Studio. One that does not appear on the list linked to above is the "nosplash" switch.  This switch disables the splash screen when starting Visual Studio, taking you directly into the IDE. Close Visual Studio and then add /nosplash after ...devenv.exe in the target of whichever shortcut you use to start Visual Studio. Starting Visual Studio now should now be quicker, possibly saving precious seconds that you could put to use elsewhere!

• Myths: Does Deleting the Cache Actually Speed Up Your PC?

  - by The Geek

  Every time you ask somebody with a reasonable level of tech skills what you should do to speed up your PC, they start jabbering on about running ccleaner and clearing the cache. But does the act of clearing a cache really speed things up? Nope. Most people assume that all temporary files are just clutter created by lousy applications, but that isn’t actually the truth. Cache files are created by apps to store commonly used information so it doesn’t have to be generated or downloaded again.

• khotkey script calling bindings stop to work on switching to Quantal

  - by Adobe

  I have many scripts which I call with khotkey. For example I have a hotkey which executes: bk_starts_or_brings.bash 'Konsole' konsole On updating to Quantal -- it stops to work: if I call that key -- it searches bk_starts_or_brings.bash 'Konsole' konsole in google in default web-browser. I tried: sudo apt-get install --reinstall libgl1-mesa-glx libgl1-mesa-dri xserver-xorg-core sudo dpkg-reconfigure xserver-xorg sudo apt-get install build-essential cdbs dh-make dkms execstack dh-modaliases fakeroot libqtgui4 When I start the command from konsole -- it works as expected, but when I call it with khotkey -- it doesn't. I guess someone shadows my keybiding. Or some daemon is not run on startup.

• How do I get started with HTML5? [closed]

  - by daniel.sedlacek

  What is the recommended workflow to learn HTML5? What tools should I install? What SDK? Where to start? How to test? How to debug? What do I read? I understand that what is often labelled as "HTML5 development" is in fact a mixture of HTML, CSS, JS and more, however I don't believe that bigger projects are developed in Notepad. That is why I am asking you to reveal your tips and tricks about your workflow.
