• Ubuntu 13.10 not playing DVD videos

  - by John Hill

  I installed Ubuntu Gnome 13.10 on my computer yesterday, and everything seems to be working fine so far, except that it isn't reading video or audio CD's and DVD's. At first, I inserted a DVD video, and it played normally for maybe 30-45 seconds before coming up with a "internal read error" or something like that. I was using the Totem player when the problem occurred, so I tried installing the VLC media player. It wouldn't read the disc at all, so I uninstalled the player. Now, the Totem player won't even begin playing the DVD. The player sometimes doesn't even open up when I insert the DVD, and other times it will but says it can't read it. I've tried several different DVD's and CD's with similar results. The computer is recognizing the optical drive, because when I open "Files", it shows the drive and the disc, but can't play it. Previously, I ran Ubuntu 13.04 with the Gnome desktop installed from the software center, and I had no issues. Any help is appreciated!

• Printing PowerPoint slides in black and white

  - by John Paul Cook

  When I do SQL Server training, sometimes students want to print all of the PowerPoint slides and use them for note taking during class. For such purposes, the background is usually better off being suppressed. This is most efficiently done by changing Print Settings as shown below: Personally I recommend that people take notes directly in the slides instead of printing them. PowerPoint has a notes area. If you do want to print slides and notes, once again use the Print Settings to specify this:...(read more)

• Dual monitor working incorrectly on a Dell XPS 8300 with an AMD Radeon HD 6450

  - by John

  I have been having trouble with Ubuntu on my Dell XPS 8300 (Actual image of the desktop). I have heard that the AMD Radeon HD 6450 has trouble with Ubuntu, and I believe that it is the source of the problem (though I am no expert by any means). When I boot the computer and choose to run Ubuntu, on a rare occasion both monitors (I have an AOC and a Samsung) will display their correct desktops, however most of the time, one of the desktops will be shifted away from its proper position and awkwardly positioned on the screen (showing the login box in the middle/right etc). If anyone has any advice on how to fix this, that would be greatly appreciated.

• Force www. on multi domain site and retain http or https

  - by John Isaacks

  I am using CakePHP which already contains an .htaccess file that looks like: <IfModule mod_rewrite.c> RewriteEngine on RewriteRule ^$ app/webroot/ [L] RewriteRule (.*) app/webroot/$1 [L] </IfModule> I want to force www. (unless it is a subdomain) to avoid duplicate content penalties. It needs to retain http or https Also This application will have multiple domains pointing to it. So the code needs to be able to work with any domain.

• What to do when Ubuntu 13.10 64-bit does not boot?

  - by Anonymous John

  Ubuntu 13.10 will not boot, it won't even show the grub menu or Ubuntu booting. There is just a purple screen for 20 seconds then a black screen, then the screen says entering power save mode. here are my system specs:Intel DQ965GF Motherboard (OS independant), Intel core 2 64-bit, 12GB HHD (SATA), 200GB HHD (SATA, installed here), 250GB HHD (SATA, Encrypted with LUKS), 3GB DDR2 RAM (DIMM 0 A 1024MB,DIMM 1 A 524MB, DIMM 0 B 1024MB, DIMM 1 B 524MB),2 Rewritable DVD drives (one SATA and one IDE), small floppy drive and car reader, and AMD gallium 0.4. That's all I know from the top of my head, I have no OS to give me more info on the graphics card, but all Ubuntu OSs worked on my PC from 12.04-13.04 just fine. Does this mean will never be able to use Ubuntu 13.10? I think I am screwed.

• If your algorithm is correct, does it matter how long it took you to write it?

  - by John Isaacks

  I recently found out that Facebook had a programming challenge that if completed correctly you automatically get a phone interview. There is a sample challenge that asks you to write an algorithm that can solve a Tower of Hanoi type problem. Given a number of pegs and discs, an initial and final configuration; Your algorithm must determine the fewest steps possible to get to the final configuration and output the steps. This sample challenge gives you a 45 minute time limit but allows you to still test your code to see if it passes once your time limit expires. I did not know of any cute math solution that could solve it, and I didn't want to look for one since I think that would be cheating. So I tried to solve the challenge the best I could on my own. I was able to make an algorithm that worked and passed. However, it took me over 4 hours to make, much longer than the 45 minute requirement. Since it took me so much longer than the allotted time, I have not attempted the actual challenge. This got me wondering though, in reality does it really matter that it took me that long? I mean is this a sign that I will not be able to get a job at a place like this (not just Facebook, but Google, Fog Creek, etc.) and need to lower my aspirations, or does the fact that I actually passed on my first attempt even though it took too long be taken as good?

• Should I extract specific functionality into a function and why?

  - by john smith optional

  I have a large method which does 3 tasks, each of them can be extracted into a separate function. If I'll make an additional functions for each of that tasks, will it make my code better or worse and why? Edit: Obviously, it'll make less lines of code in the main function, but there'll be additional function declarations, so my class will have additional methods, which I believe isn't good, because it'll make the class more complex. Edit2: Should I do that before I wrote all the code or should I leave it until everything is done and then extract functions?

• Web-based data generator

  - by John Paul Cook

  One of my coworkers told me about Mockaroo , a web-based data generator. I needed some test data for upcoming blog posts, so I decided to give it a try. It’s pretty good. I had to use Firefox because of problems running Mockaroo on Internet Explorer 11. Using the defaults except for changing the format to SQL, it generated output that looked something like the following. Mockaroo is so good that it generates fake data that could accidentally be real, such as email addresses. Consequently, I edited...(read more)

• No sound after clean install

  - by John Cheednik

  Did a clean install of Ubuntu 12.10 and everything working great except for the sound. Ubuntu doesn't even seem to be recognizing the fact my HP dv6000 has the capability of making sound! I have the dummy output problem, and when I try to open alsamixer using terminal I get the message that no such file or directory exists. I can't get it to recognize any soundcards or audio devices at all. I've been working on the problem for a couple days now and have even taken the laptop apart to ensure that all cables are properly attached... When I go into the PhoenixBIOS there are no sound options that I can find. The laptop does make a loud beep if I press buttons in the BIOS, but once it boots to the hard drive, the thing is mute. HELP!

• How do I rip a dvd including menus and extras to a menu driven divx file (or any lossy format that supports menus)?

  - by John Baber

  I am asking exactly this question for the same reason, but would like to archive dvds as small, low quality video, while preserving the menu choosing experience. I would like to rip my dvds to something that has the same menus but whose video is in a much more compressed format. I do not want to copy a dvd to an .iso image. How can this be done in the most automatic (hopefully CLI) way possible? Any format is fine so long as playback on linux is possible.

• Genetic Considerations in User Interface Design

  - by John Paul Cook

  There are several different genetic factors that are highly relevant to good user interface design. Color blindness is probably the best known. But did you know about motion sickness and epilepsy? We’ve been discussing how genetic factors should be considered in user interface design in one of my classes at Vanderbilt University School of Nursing. According to the National Library of Medicine, approximately 8% of males and 0.5% of females have red-green color discrimination problems with the most...(read more)

• Dash brings up 2nd instance of an app

  - by John Rose

  When I select an app from the Launch panel, it returns to the app if already loaded (i.e. shows the app's window with the 'old' situation in it, such as the document last worked on by LibreOffice Writer). However, if I click on the app after clicking the Dash icon in the Launch panel, it always seems to bring up a new instance of the app. Is there a way to make the Dash return to the app as per direct selection of the app from the Launch panel.

• Working with legacy data

  - by John Paul Cook

  We encounter legacy data as a part of life. Colleges and universities have transcript records dating back decades or even centuries. Real estate property records in the United States go as far back as Spanish and British land grants in the 1500s. Very old records are completely paper based and may be completely manually prepared, perhaps typed on a typewriter or written in longhand with a quill pen. How long should transcripts be retained?

• Why is purchasing Microsoft licences such a daunting task? [closed]

  - by John Nevermore

  I've spent 2 frustrating days jumping through hoops and browsing through different local e-shops for VS (Visual Studio) 2010 Pro. And WHS (Windows Home Server) FPP 2011 licenses. I found jack .. - or to be more precise, the closest I found in my country was WHS OEM 2011 licenses after multiple emails sent to individuals found on Microsoft partners page. Question being, why is it so difficult to get your hands on Microsoft licenses as an individual? Sure, you can get the latest end user operating systems from most shops, but when it comes to development tools or server software you are left dry. And companies that do sell licenses most of the time don't even put up pricing or a self service environment for buying the licenses, you need to have an hawk's eye for that shiny little Microsoft partner logo and spam through bunch of emails not knowing, if you can count on them to get the license or not. Sure, i could whip out my credit card and buy the VS 2010 license on the online Microsoft Shop. Well whippideegoddamndoo, they sell that, but they don't sell WHS 11 licenses. Why does a company make it so hard to buy their products? Let's not even talk about the licensing itself being a pain.

• 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?

• Avoiding "double" subscriptions

  - by john smith

  I am working on a website that requires a bit of marketing; let me explain. This website is offering a single, say, iTunes 50$ voucher to a lucky winner. To be entered in the draw, you need to invite (and has to join) at least one friend to the website. Pretty straightforward. Now, of course it would be easy for anyone to just create a fake account and invite that account so, I was thinking of some other way to somehow find out of possible cheating. I was thinking of an IP check on the newly subscribed (invited) user, and if there is the same IP logged in the last 24 hours, and if that's the case, investigate more about it. But I was thinking that maybe there is a more clever way around this issue. Has anyone ever though about this? What other solutions did you try? Thanks in advance.

• Matching my skills with Java and Web Programming

  - by John R

  here is my main question: What is the most common way that Java is used in web development? The reason I ask: I am currently in the process of finding my first internship. Every employer has a separate set of languages, technologies and acronyms they want their candidates to know. In school I did well with Java. As a hobby and interest I have developed a handful of web pages widgets, scripts, etc. My university emphasized Java, C and theory. My hobbies emphasize HTML, PHP, JavaScript, CSS, and a little jQuery, etc. I can't learn a dozen different technologies to satisfy most prospective employers (in what is left of the summer). I think my best bet is combine my skills with Java and my interests in web development. That brings me back to my original question: What is the most common way that Java is used in web development?

• Parse text file on click - and then display

  - by John R

  I am thinking of a methodology for rapid retrieval of code snippets. I imagine an HTML table with a setup like this: one two ... ten one oneTwo() oneTen() two twoOne() twoTen() ... ten tenOne() tenTwo() When a user clicks a function in this HTML table, a snippet of code is shown in another div tag or perhaps a popup window (I'm open to different solutions). I want to maintain only one PHP file named utitlities.php that contains a class called 'util'. This file & class will hold all the functions referenced in the above table (it is also used on various projects and is functional code). A key idea is that I do not want to update the HTML documentation everytime I write/update a new function in utilities.php. I should be able to click a function in the table and have PHP open the utilities file, parse out the apropriate function and display it in an HTML window. Questions: 1) I will be coding this in PHP and JavaScript but am wondering if similar scripts are available (for all or part) so I don't reinvent the wheel. 2) Quick & easy Ajax suggestions appreciated too (probably will use jquery, but am rusty). 3) Methodology for parsing out the functions from the utilities.php file (I'm not to good with regex).

• Windows Not Sleeping All Night

Network adapter Power Management tab. That didn’t solve the problem. I included the screen capture in Figure 1 because it could be part of the solution for someone else.

• Dropbox install stuck at 99%, how do I fix it? (and any dpkg errors)

  - by John

  I tried to install Dropbox using How to install Dropbox?, or with apt-get install nautilus-dropbox. Dropbox loads until 99% and then hangs, causing the system to go to 100% cpu usage. If I reboot or close the terminal, I sometimes get dpkg errors which prevent me from using apt-get or Software Center to perform any package management functions. I would like to resolve all these and just get Dropbox working. How do I do that? Note: This question is possibly answered in two parts: The accepted answer tells you how to install Dropbox. But if you have dpkg errors, see this answer before you use answer 1 to install Dropbox.
