• Installing g++ on 8.04

  - by mathematician1975

  I am running Ubuntu 8.04 (currently I do not have the option to upgrade due to hardware problems). I need to get g++ onto my installation but as this is no longer supported I am unable to use the traditional apt-get approach. What are my options? Are ubuntu packages configured specifically for each version? For example could I manually download a later version of gcc and g++ that do not originally ship with 8.04 (say the 10.04 version for example) and build them from scratch? Do the compilers work in this way in the sense that they have a version PER ubuntu version or are they maintained as separate entities?? I do not know enough about ubuntu internals really and always use apt-get to obtain/update any packages I need. If it is possible to do it this way is there a way to be certain that I have everything I need with regards to utility packages needed by g++ for the installation??

• Cloudflare displaying cached CSS in-line?

  - by esqew

  I recently enabled CloudFlare on my domain, and when I make HTML statements like this: <link href="css/main.css" rel="stylesheet" /> The CSS gets displayed in-line, like this: <style>body{padding-top:40px}span.light{font-weight:lighter!important}span.title{font-size:60px;line-height:1;letter-spacing:-1px;color:inherit}</style> When I update the file via FTP, the changes are not reflected, which leads me to believe that this is a caching issue. Is this due to CloudFlare? If so, how do I disable the behavior? EDIT I also came to the conclusion that caching is behind the behavior after being able to see changes in the page after re-naming the CSS file.

• How do I best remove an entity from my game loop when it is dead?

  - by Iain

  Ok so I have a big list of all my entities which I loop through and update. In AS3 I can store this as an Array (dynamic length, untyped), a Vector (typed) or a linked list (not native). At the moment I'm using Array but I plan to change to Vector or linked list if it is faster. Anyway, my question, when an Entity is destroyed, how should I remove it from the list? I could null its position, splice it out or just set a flag on it to say "skip over me, I'm dead." I'm pooling my entities, so an Entity that is dead is quite likely to be alive again at some point. For each type of collection what is my best strategy, and which combination of collection type and removal method will work best?

• Using apt-get from Canada

  - by Advant Edge

  I am using Ubuntu Server 12.04 LTS, and until yesterday, everything was quite peachy. I have installed several packages (MySQL, apache2) and to my knowledge have those configured correctly. Upon configuration of phpMyAdmin, I found that I was missing the directory path /etc/phpmyadmin, which got me thinking about the install. I am new to Ubuntu, so I guess I missed the message telling me that I did not download phpMyAdmin successfully. Anyway, trying to use apt-get yesterday/today results in "Failed to fetch..." messages, even if just to run sudo apt-get update. Some notable details: ···no GUI, command line only (sudo apt-get gksu fails, go figure) ···can ping 4.2.2.2, so I know the internet is out there (somewhere) ···this is a dedicated computer, using Samba to share files with Windows, which does work ···attempted to edit my /sources.list file, for various American/Canadian mirror, to no effect ···ensured I have correct DNS settings in /etc/networks/interfaces I'm not sure where along the way it happened, but I seem to have lost connections to repositories... :) Any advice (including GO BACK TO WINDOWS) is appreciated.

• How to Enable SideLoading in a SharePoint Site

  - by Damon Armstrong

  I was trying to deploy a SharePoint App for the first time and ran into an error about SideLoading not being enabled on the site. The solution is fairly simple – you just have enable the Developer feature on the site.  Unfortunately, it’s a hidden feature so you have to do it through PowerShell.  While searching the internet for the command to enable the feature I kept running into really long scripts that seemed overly complicated.  Fortunately, Jeff (a friend at work) sent me this snippet that is very concise and does the job: Enable-SPFeature e374875e-06b6-11e0-b0fa-57f5dfd72085 –url http://yoursharepointbox/site/ Obviously, you will need to update the URL to match your environment!

• What options do I have for a Wedding Car website? [on hold]

  - by David

  I currently run a Wedding Car website that is ranking in the top 5 for my local area, its not doing so well outside of that. I have listed the company in Google Business so it shows in the SERP and I have a Facebook and Twitter account linked, that I update regularly.

I am totally unsure where to go with this website, the site currently has a few images and a small amount of text. Things I am considering, but would like advice on: A Mobile version of the website A Blog on the website A gallery page with pictures and descriptions Asking local companies to link to my website Essentially I have a small business website but not much content, because really there isnt! I am looking for long term organic ways to get a good seo rank.

• Where do you get new software ideas from? [closed]

  - by Cape Cod Gunny

  The world of software creation is very competitive. I've heard it said to be successful you need to be the first one with the idea. Everyone knows how Bill Gates created IBM DOS on one machine while simultaneously building MS-DOS on another machine (and we all know how that turned out). In order to be the first to come up with a new software product, where do you go looking for fresh ideas? Update 06/26/13: Reworded this question in an attempt to get it reopened. Bill Gates developed MS-DOS at the same time he was hired to develop IBM DOS. As a programming community, we would all gain by understanding how to think up great ideas for software. As programmer we tend to get stuck in our thinking... it's refreshing to hear how fellow programmers busted out and came up with their ideas. It's not very likely that we will have an MS-DOS opportunity like Bill Gates. Please vote to reopen.

• Where does ntpdate get its settings from and what is the "no servers can be used" error about?

  - by wilhil

  When I run ntpdate on its own, I get the following output: 8 Jun 15:47:46 ntpdate[31251]: no servers can be used, exiting If I run it with the -q ntp.ubuntu.com switch, it seems to query just fine. I have been hunting through many files and the most relevant one I have found is /etc/default/ntpdate, however, even with NTPDATE_USE_CONF set to no, I just can't understand/see how this error is occurring Any ideas? Update-- been looking non stop... It appears that ntupdate-debianworks fine and is the actual command that makes use of /etc/default/ntupdate, but, this doesn't answer the main question and I still can't find it...

• Is executing SQL through a WebService a really bad idea?

  - by Kyle

  Typically when creating a simple tool or something that has to use a database, I go through the fairly long process of first creating a webservice that connects to a database then creating methods on this webservice that do all the type of queries I need.. methods like List<Users> GetUsers() { ... } User GetUserByID(int id) { ... } //More Get/Update/Add/Delete methods Is it terrible design to simply make the webservice as secure as I can (not quite sure the way to do something like this yet) and just make a couple methods like this SqlDataReader RunQuery(string sql) { ... } void RunNonQuery(string sql) { ... } I would sorta be like exposing my database to the internet I suppose, which sounds bad but I'm not sure. I just feel like I waste so much time running everything through this webservice, there has to be a quicker yet safe way that doesn't involve my application connecting directly to the database (the application can't connect directly to database because the database isn't open to any connections but localhost, and where the appliction resides the standard sql ports are blocked anyway) Especially when I just need to run a few simple queries

• What is the best certification for the self-taught ASP.Net programmer? [closed]

  - by Wahid Bitar

  I learned the C#.Net language from books and many other resources then i did some good projects with ASP.Net "Web Forms & MVC". But i wanna a good certificate to get a better work out of my country as i suppose. I've two choices: Apply for a " college / institute " and start study academic courses to be more professional and maybe in two years I'll "hopefully" graduate with this college certificate. Apply for kind of " Certifications by Companies " like MCTS from Microsoft or something like that and study their straightforward courses then maybe with three or four months I'll get this "Not official Certificate". Is the second type of certifications good for learning and work or the best is the hard way ?. Please give me advises with certifications names please. ======================= Update: This is not related to certain country or region. I'm asking about a good certification and courses for an ASP.Net and C# in general programmer.

• Rebooting yes, Shutdown no

  - by Chiotis Leonidas

  Hello everyone and thanks in advance. I am new in Ubuntu and have the 12.04 version dual boot with Windows XP. I have the following problem. The laptop can reboot using the reboot option from the menu but it cannot shut down. It starts shutting down, the dots appear but then it freezes and does not turn off. Sometimes it shuts down normally (usually just after an update) but then it loses that capability again. Some strange things, I noticed that when the dots freeze, the USB mouse loses power, BUT the usb-powered cooling pad continues to work The only Fn shortcuts that work all the time are the Volume up, down and mute, BUT sometimes when the other Fn combinations (screen-off etc) work the computer shuts down normally I searched a lot on my own, please help.

• Why does the BADSIG/"Untrusted sources" error recur forever?

  - by Jeff McMahan

  On at least a dozen occasions, I've spent 2-3 hours figuring out how to get Ubuntu 11.10-12.10 to either update or acquire software from software center, or both. I want to fix whatever is causing the BADSIG problem once and for all; I've wasted so much time trying to get this to work well enough that I can rely on it, but the same problem comes back after a couple weeks of normal updates and software center usage. Don't refer me to a standard posted solution on the web---whatever it is, I've used it more times than you have. The question isn't whether I can get it to work right this afternoon. I can. The question is what is causing the problem to recur regularly across 3 releases. Notice: I use this computer 4-5 hours per week and I do little on it. PDFs, Latex, FireFox, Mendeley, and that's it. I don't constantly install new software, and I don't fiddle with things unnecessarily.

• Transfer domain from godaddy to another registrar and (somewhat) maintain privacy?

  - by anonymous-one

  Does anyone know if its possible in any ways to do this? Transfer a private domain (via domainsbyproxy) registered at godaddy to another registrar. While I know moving a domain from godaddy requires the privacy to be disabled, what we were thinking of doing is the following: a) Update the whois info inside domains by proxy to a 3rd party. Most likely a law firm who would in essnece become our 'custodian'. b) Wait 60 days (?) c) Disable domain privacy. Now the law firms details would become public. d) Conduct the domain transfer. e) Take ownership of the domain at the new registrar. Does something like this sound possible? Does anyone know any other way to handle this? Thanks.

• What is a good design pattern and terminology for decoupling output?

  - by User

  I have a program where I want to save some data record. And I want the output type to be flexible such that I could save the data record to a text file, xml file, database, push to a webservice. My take on it would be to create an interface such as DataStore with a Save() method, and the concrete subclasses such as TextFileDataStore, DatabaseDataStore, etc. What is the proper name/terminology for this type of pattern (I'm using the term "DataStore", log4net names things "appenders", .net they talk about "providers" and "persistence")? I want to come up with good class names (and method names) that fit with a convention if there is one. can you point me to a decent example, preferably in C#, C++, or java? Update Managed to find this stack overflow question, Object persistence terminology: 'repository' vs. 'store' vs. 'context' vs. 'retriever' vs. (…), which captures the terminology part of my question pretty well although there's not a decent answer yet.

• How to install programs downloaded from the internet?

  - by Rosamunda Rosamunda

  I've downloadad the latest XAMPP file, to install it into Ubuntu 13.04. After downloading the file, I just can run it. I've double click it (and I've tried right click and clicking "open", whith the same result). All the answer I get is this message: Could not display “xampp-linux-1.8.3-1-installer.run”. There is no application installed for “executable” files. Do you want to search for an application to open this file? I've tried searching for an application, with no result... Also, I haven't found any questions related to this issue with the 13.04 Unity version... I've tried this solution, with no result. Please note that this isn't a Xampp question, the same happened to me when I tried to install Skype. UPDATE: I've tried this solution: cd ~/Downloads chmod +x myfile.run sudo sh myfile.run And I've got this error: Syntax error: "(" unexpected What should I do? Thanks!

• How to eliminate an old Ubuntu partition?

  - by GUI Junkie

  I installed Ubuntu 12.04 64-bit side by side with my previous 11.10 32-bit. As everything is working correctly, I want to eliminate the old partition. According to update-grub: Found Ubuntu 11.10 (11.10) on /dev/sda1 But according to GParted, /dev/sda1 is the boot partition! So, how can I discover which partition should be the boot partition for 12.04? Can I safely eliminate the /dev/sda1? Also, GParted gives /dev/sda5 as file system unknown, it's 2.93Gib and might be the swap partition (just guessing).

• Include in service layer all the application's functions or only the reusable ones?

  - by BornToCode

  Background: I need to build a main application with some operations (CRUD and more) (-in winforms), I need to make another application which will re-use some of the functions of the main application (-in webforms). I understood that using service layer is the best approach here. If I understood correctly the service should be calling the function on the BL layer (correct me if I'm wrong) The dilemma: In my main winform UI - should I call the functions from the BL, or from the service? (please explain why) Should I create a service for every single function on the BL even if I need some of the functions only in one UI? for example - should I create services for all the CRUD operations, even though I need to re-use only update operation in the webform? YOUR HELP IS MUCH APPRECIATED
