• Advice on what to learn? [closed]

  - by ICTech

  Currently I work as a .NET C# programmer, quite fresh faced at that (only been working professionally for 8 months) I'm enjoying what I'm doing, but I'm now thinking ahead for other languages to learn. I've heard from quite a few seasoned developers that they reckon it's worth getting in to HTML5. Before I asked this question I read a few of the other questions similar to this, but most were dated back a few years. I'm wondering what your advice would be to an aspiring programmer, what I should avoid going for (i.e. as I understand it Flash is essentially going to be phased out due to HTML5) I was looking in to WPF and the more updated .NET technologies, but someone advised me that WPF stuff will probably be redundant in the future. Thanks for your advice and opinions :)

The documentation for my webapp reads as follows: you will need to create following cronjob: /public_html/cake/console/cake -app /public_html/app master Also, I want any output written to a log file.

• MediaWiki plugin for dynamic content via forms

  - by Geek42

  Are there any plugins for MediaWiki that would allow me to create a page that has a form at the top that when filled in populates tags further down in the document? Say someone would put a form with "Source Server:" and "Destination Server:" fields at the top. Once those were typed in it would automatically populate those names into the content lower so that when following the instructions you could just read the docs and not have to mentally replace things, and possibly mess it all up. I'm not looking to make pages that are permanent, just ones that can have values entered before they are followed. Any suggestions?

• If I am in the USA, should I not have a hosting provider in another country? [on hold]

  - by johnny

  I saw the various questions on SO about this. I'm not sure they answered me. I'm in the USA. Someone asked me about hosting on a company in South Africa. They are not a big company. This person simply liked the company for whatever reason. I only saw one horror story. Not many reviews really. It is a small outfit from what I can tell. But, the fact of it being in South Africa, does that matter? Do people ever pursue legal action against hosting companies anyway? The users will all be in the States. edit: I'm not sure why this is unclear.

• Encrypted Ubuntu Partition HELP!

  - by user207984

  I had Zorin 7 Encrypted. I accidentally deleted important GRUB data trying to make more room in the boot folder i think? So the computer would no longer boot up. Anyways, I installed a second Linux OS on the same laptop, but I am unable to access all of my important information that is still on the encrypted partition. When i go to mount it to access everything, it asks for the encryption password... however, it tells me the password is incorrect, which I know 100% that it is the correct password. Someone please help me! Inform me how I can access this encrypted partition or restore the data so that I can boot the computer in Zorin 7 again.

• Scrum in a consulting environment?

  - by Darla

  Is it possible to introduce scrum to a consulting environment? On any given week I might belong to 4 different teams, each with a different PM, BA and dev team (I am a designer). It doesn't seem feasible, time wise, to be able to be part of that many teams/projects as there would need to be daily stand-ups for each, sprint reviews, etc. I should add these projects are not necessarily software, but mainly ecommerce web projects. Can someone who has done this speak to how you approach it?

• Ubuntu Server 11.10 AMD64: Installation of graphical desktop changes kernel!?

  - by MindGap

  I've a Ubuntu Server 11.10 amd64 installation that needed a graphical desktop to execute some visual apps. While searching for the correct way to achive this, I noticed that there was a lot of people saying that invoquing the gnome desktop installation (apt-get install ubuntu-desktop) would switch from server to desktop kernel. Is this true!? I've checked and the kernel seems to remain unchanged after the install. I need to be sure of this because the desktop flavoured kernel doesn't seem to support the ServeRaid 8K controller sitting on my IBM server and I have no ideia on how to enable support for it. (I'll be grateful if someone could point me a good guide on how to install ubuntu when the storage controller is not detected) Any comment on this matter will be greatly appreciated! Good linuxing!

• Are these interview questions too difficult for entry-level C++ positions?

  - by Banana

  I recently had a few interviews for programming jobs within the financial industry. I am looking for entry-level positions as I specify in the cover letter. However I am usually asked questions such as: - all two-letters commands you know in unix - representation of float/double numbers (ieee standard) - segmentation fault memory dump, and related issues - all functions you know to convert string to integer (not just atoi) - how to avoid virtual tables - etc.. Is that the custom? Because I don't think this kind of questions make sense for someone willing to get an entry-level job. Is it totally crazy to think that they should ask more conceptual questions? This is beginning to driving me nuts, honestly. Thanks

• Ubuntu Software Center is crashing while trying to install psychonauts

  - by GonzoDark

  I am having a problem installing Tim Schafers epic platform video game Psychonauts trough the Ubuntu Software Center. I have bought the game on http://www.humblebundle.com/ and I have used the new redeem option introduced in this bundle: "redeem your bundle on the Ubuntu Software Center." When I have downloaded approximately 2.1 GB of Psychonauts then Ubuntu Software Center starts to repeatedly crash and pop-up with a new crash report dialog every few seconds (before previous ones are closed and that will crash the computer after a few min, unless I stop the download). I also have a file-size bug, where Ubuntu Software Center tells me that I have downloaded 880,2 MB out of 133,3 MB I use the new Ubuntu 12.04 LTS and Ubuntu Software Center version 5.2.2.2 (©2009-2011 Canonical <--- That is also a bug, should be 2012 I guess) I hope someone can help me.

• Cannot access my own web page

  - by enflam3

  I am developing, learning and experimenting with php,html,javascript,flash and so on. Having web hosting and all of the cpanel, phpmyadmin and other utilities. One day, while updating information, connection between my computer and website just went down. I found out that it is only from this computer, where I cannot access anything. I don't know what is the reason I cannot access website, however this is what I have checked so far: Everything else opens normally, having problem only with my page. Cannot access FTP,cpanel or any kind of information related to the domain and hosting ipconfigs detects IP, but shows request timed out (so its not browser related) Turned off Firewall,AV, Rebooted computer Cleared caches,temp,cookies,histry with CCleaner Checked connectivity with both (wired,wireless) networks ISP has dynamic IP that has been changed about 3 times since issue Checked host file I am out of ideas and understanding what could cause this kind of issue, however couple minutes ago, found out that everything works with proxy server (when adding IP and port to the browsers) Can someone point out what should I check or try to get rid of this problem?

• How do I calculate the motion of 2 massive bodies in space?

  - by 1224

  I'm writing code simulating the 2-dimensional motion of two massive bodies with gravitational fields. The bodies' masses are known and I have a gravitational force equation. I know from that force I can get a differential equation for coordinates. I know that I once I solve this equation I will get the coordinates. I will need to make up some initial position and some initial velocity. I'd like to end up with a numeric solver for the ordinal differential equation for coordinates to get the formulas that I can write in code. Could someone break down how from laws and initial conditions we get to the formulas that calculate x and y at time t?

• Any good stories or blog posts of a startup's server/stack evolving as they got bigger? [closed]

  - by user72245

  I know lots of startups often go for practical, simple, efficient. So maybe tossing a Ruby program on a basic Apache server. Get some users up and running, etc. Then Ruby starts to not be fast enough, so they throw more servers at the problem? And load balancing or something? And then when stuff gets REALLY crazy, language changes, etc? I'm looking for someone who has cleanly and simply told their own company's story like this. Are there any good ones?

• Trying to install/dual boot

  - by user292236

  I have widows 8 (Pre-installed), and I was not a fan. So I thought I would try Ubuntu as many people from what I hear that use it, like it, and hey, free OS. Well before I was able to do all the instalations, I had to goto work, so my girlfriend (whio is not at all tech savy) decided to help. She told me she installed it, (It popped up with a thank you for installing message) She then shut it off. When she turned it on, when I turn it on, I boot right to windows, I have never installed a secondary OS. And I was hoping someone with more experiance than I could walk me through what I need to do in order to be able to dual boot Ubuntu version is 14.04 and 64bit

• How do I access an external hard drive plugged into my router?

  - by Shawn

  I am running Ubuntu 11.10 and I own a Netgear N600 Wireless Dual Band Router with a USB port built into it. Naturally, the router came with instructions on how to mount and view this drive with both Windows and Mac, but nothing about Linux. I have an WD Elements 1 TB external HDD that I would like to plug into the router and share across my home network. However, when I plug it in, absolutely nothing happens on my desktop. I checked on two different machines and nothing seems to indicate that the drive has been mounted (or is even seen at all) on either machine. I am fully aware that it may not be possible to do this with a Linux system, but I was hoping someone might have a suggestion. Thanks!

• Fixing a broken toolbox (In Visual Studio 2010 SP1)

  - by mbcrump

  I was recently running into a situation where every time I opened Visual Studio 2010 SP1, the following message would appear for about 60 seconds or so: "Loading toolbox content from package Microsoft.VisualStudio.IDE.Toolbox.ControlInstaller.ToolboxInstallerPackage '{2C98B35-07DA-45F1-96A3-BE55D91C8D7A}'" After finally get fed up with the issue, I started researching it and decided that I’d share the steps that I took to resolve it below: I first made a complete backup of my registry. I then removed the following key: [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\VisualStudio\10.0\Packages\{2c298b35-07da-45f1-96a3-be55d91c8d7a}] I went to the following directory: C:\Users\Your Name Here\AppData\Local\Microsoft\VisualStudio\10.0\ and created a folder called bk and moved the .tbd files to that folder (they are hidden so you will have to show all files). I then removed the .tbd files in the root directory. I then launched Visual Studio 2010 SP1 again and it recreated those files and the problem was gone. Anyways, I hope this helps someone with a similar problem. I created this blog partially for myself but it is always nice to help my fellow developer.  Thanks for reading. Subscribe to my feed

• How can I tell what error grub has when I can't read what it's saying?

  - by RolandiXor - The Ice Man

  Grub won't allow me to get into any systems on my HP dv7 (it runs 12.10). As the screen is broken, I can't read what the error is. Nothing works, not even the recovery mode. It gives me some error about "cannot find" (I think) and Press any (I guess key?) When a press a key I'm dropped back to the menu. At the moment I'm trying all the recovery options I know. However, it would be great if someone could tell me how to know what error grub is facing from a live cd or something (maybe a log file or something could help)? NB: I can view the filesystem from a liveCD, and I did check the filesystem - it was clean.

• 12.04 reboots rather than shutting down

  - by Luca

  I have a ruvo with a fresh installation of 12.04. When I try and shutdown the computer reboots. Until I upgraded (by doing a fresh install) I ran it with Ubuntu 10.04 and I didn't have this issue. I have tried sudo shutdown -h now sudo shutdown -P now sudo init 0 sudo poweroff All of these cause a reboot. I have added acpi=norq to my grub file as suggested by someone in the first post below. This is being used as a mythtv frontend and I would like the power button to shut it down. I have modified the button to perform a shutdown -h now, but this too causes a reboot. I have studied the posts below and tried some of these ideas, but with no luck so far. Why do I get a reboot instead of a shutdown? Ubuntu 12.04 not shutting down properly Stuck on reboot and shutdown Shutdown does not power off computer

• Why does Evolution give me multiple reminders for the same event?

  - by Dylan McCall

  I have a bunch of calendars on my Google Calendar account (school & work, personal, etc.), so I have Evolution subscribed to each one of those calendars. When I get a notification for an upcoming (recurring) event, I actually get many notifications for the same event, all at the same time. For example, just now I got 21 notifications for one event. I am using Gnome Shell, where the message tray displays event notifications in its own way. I get the same behaviour on my other computer, also running Ubuntu 11.10 with Gnome Shell. (And it has happened running Unity where Evolution only shows its dialog window with event reminders, but I'm not sure if it has happened quite as intensely). Does someone know why this is happening, and maybe how to fix it? It would be cool to get slightly less panic-inducing event reminders :)

• HTAccess redirect directories to index.html

  - by BFTrick

  Hi there, I am working on a site that where I do not have permission to the server and someone else keeps changing the settings. That person just changed the settings preventing users from going to example.com/foo/ and seeing the index page. This Virtual Directory does not allow contents to be listed. If you type in example.com/foo/index.html you can still see the file. So I want to use htaccess to redirect all urls that end in a directory to change into directory/index.html How do I write that? I started with some code that changes .php files to .html files and tried to work from that but I couldn't quite get it to work. RewriteRule ^(.*)\.php$ /$1.html [R=301,L] Any suggestions?

• Online job application

  - by Fred

  I am trying to add an application to my site where I can post job openings with my company and allow people to apply online. Can someone recommend a service or app already in existence for this purpose? I tried googling it, but could not find a set of search terms that did not return endless sites for job seekers. This is a (very) small business and I do not expect to have more than a few openings at any time, but what I am actually interested in is having a repository of interested job seekers to have on file. Then when people ask me about openings, I could just refer them to the page and they could apply. Then, if we have an opening, we could look through the list of candidates and if we can't fill the position(s) from that list, we could post the job and advertise to fill the position.

• Good interview programming projects

  - by bigtang

  I'm looking for some small programming projects that I can give potential employees to gauge their programming abilities. These will be programmers straight out of college. I'm looking for projects that would take someone a couple of hours and they would email back their answers post-interview. One example would be to take this paragraph of text and return a list of alphabetized unique words. After each word tell me how many times the word appeared and in what sentance(s) the word appreared in. Anyone have any good suggestions?

• How do I install drivers for graphics and sound?

  - by Sid

  I recently shifted to Ubuntu 12.04 from windows 7. I completely removed Windows and then installed Ubuntu. However, I can't find a way to download and install drivers for my video and audio hardware like I used to be able to do in Windows. Could someone please explain to me how software and drivers, in general, are installed on Ubuntu. Is installing through 'Ubuntu Software Center' the only way to install them? My laptop model is: Dell Inspiron 14 N4010 (i5/4gb/500gb). Kindly help. Thanks in advance.
