• Accidentally hit shortcut and lost text in web browser. Can it be disabled?

  - by uniomni

  I have noticed that I occasionally hit some shortcut while typing that either kills the browser or otherwise causes me to lose e.g. a post I am writing. This typically happens if I type while on a bumpy road or something like that. It also just happened to my eight year old daughter ;-( I think the shortcut in question is CTRL-w which (at least in Firefox) closes the current tab and consequently whatever content is being written. I would like to know if anyone has noticed this and if someone has a solution e.g. a way to disable "dangerous" shortcuts if at all possible. Many thanks Ole (uniomni)

• What is the command to use to put your computer to sleep (not hibernate)?

  - by airrick

  I want to put my windows pc (win7) into a sleep state via command line (so i can bind to macro button on keyboard). The power button on the PC is setup to but the computer to sleep (but it's down on the floor and I'm too lazy to reach down) it exactly how I want it (sleeps using hybrid mode in case I loose power) The sleep command on the shutdown menu also works. most info I found says to use; %windir%\system32\rundll32.exe PowrProf.dll, SetSuspendState 0,1,0 But this puts the computer in hibernate mode. I do have hibernate disabled but using hybrid sleep. So, What is the command to use to put your computer to sleep (not hibernate)?

• Why Java as a First Language?

  - by dsimcha

  Why is Java so popular as a first language to teach beginners? To me it seems like a terrible choice: It's statically typed. Static typing isn't useful unless you care a lot about either performance or scaling to large projects. It requires tons of boilerplate to get the simplest code up and running. Try explaining "Hello, world" to someone who's never programmed before. It only handles the middle levels of abstraction well and is single-paradigm, thus leaving out a lot of important concepts. You can't program at a very low level (pointers, manual memory management) or a very high level, (metaprogramming, macros) in it. In general, Java's biggest strength (i.e. the reason people use it despite the shortcomings of the language per se) is its libraries and tool support, which is probably the least important attribute for a beginner language. In fact, while useful in the real world these may negatives from a pedagogical perspective as they can discourage learning to write code from scratch.

• Python lower_case_with_underscores style convention: underscores not popular?

  - by squirrel

  PEP8 recommends using lowercase, with words separated by underscores as necessary to improve readability for variable and function names. I've seen this interpreted as lower_case_with_underscores by most people, although in practice and in Python's native methods it seems like lowercasewithoutunderscores is more popular. It seems like following PEP8 strictly would be awkward since it seems to suggest mixing both lower_case_with_underscores and lowercasewithoutunderscores, which would be inconsistent. What is your interpretation of PEP8's variable names, and what do you actually use in practice? (Personally, I like lowerCamelCase as a compromise between readability and ease of typing.)

• Lubuntu 14.04 graphics problem on portege r100

  - by user286069

  first of all I have to say that I am not an expert. I have installed Lubuntu 14.04 on my Portege R100. The problem is that the graphics session does not start. Actually I can do all but only by command line. I try to start Xsession but nothing happens. Actually by typing startx the system stop to works. I read several threads on this topic but I did not find such kind of problem. There is something similar about portege r100 concerning lowgraphics mode but the porblem I have seems to be different because graphics session does not start. Can anyone help me ? Thank you Best

• Correct way to use Farseer Physics in XNA

  - by user1640602

  I am using Farseer Physics for my 2D sidescroller game and I'm not sure how to proceed with it. I currently have a Sprite class (handles nothing but graphics), a GameObject class (contains specific object info like hit points), a World object which contains the list of Bodies, and a Level object which contains all of these objects. Originally I was trying to keep track of the Sprites, GameObjects, and Bodies separately because I felt that would provide loose coupling but it quickly became a headache. So my new idea was to add a Sprite member to the GameObject class but I'm still not sure how to maintain the Bodies because they have to communicate with GameObject. Specifically, my issue is this: The position of the Body is used to draw the Sprite inside of the Level. In order to do that I would have to maintain a link between GameObjects and Bodies. Is this correct or is there a better way to architect my game? If any of this is unclear please ask and I'll try to clarify. Thank you in advance for any help.

• Problem after upgrading to 14.04: Unable to mount - Not authorized

  - by Elisa Velasco Lorenzo

  This is the first time I ever post on this forum. I have used Ubuntu for 7 years, and every time I've had a problem, I have browsed the web and I have been able to solve it thanks to the help given on forums to other users experiencing the same issues (I do not have technical knowledge on Ubuntu). This time, I've spent hours reading forums and typing commands and nothing helps. I am exhausted. Upgrading to 14.04 has proved itself a mistake. Many things won't work anymore. But the one which worries me right now is external media not automounting anymore. I know other people have had the same issue and I have carefully read their threads, but nothing helps!!

• Add References with Search

  - by Daniel Cazzulino

  If you have been using VS2010 for any significant amount of time, you surely came across the awkward, slow and hard to use Add Reference dialog. Despite some (apparent) improvements over the VS2008 behavior, in its current form it's even LESS usable than before. A brief non-exhaustive summary of the typical grief with this dialog is: Scrolling a list of *hundreds* of entries? (300+ typically) No partial matching when typing: yes, you can type in the list to get to the desired entry, but the matching is performed in an exact manner, from the beginning of the assembly name. So, to get to the (say) "Microsoft.VisualStudio.Settings" assembly, you actually have to type the first two segments in their entirety before starting to type "Settings"....Read full article

• Is it bad practice to use <?= tag in PHP

  - by marco-fiset

  I've come across this PHP tag <?= ?> recently and I am reluctant to use it, but it itches so hard that I wanted to have your take on it. I know it is bad practice to use short tags <? ?> and that we should use full tags <?php ?> instead, but what about this one : <?= ?>? It would save some typing and it would be better for code readability, IMO. So instead of this: <input name="someVar" value="<?php echo $someVar; ?>"> I could write it like this, which is cleaner : <input name="someVar" value="<?= $someVar ?>"> Is using this operator frowned upon?

• Invoke host's workspace switcher from inside VM

  - by Paul

  When I start a virtual machine (like VMware or VirtualBox) and set it full screen then, from the host OS (in this case Ubuntu), I can beautifully switch to it with the Workspace Switcher. So I switch to the VM like I switch to a virtual screen. But switching back -- from the VM to the host's virtual screens -- seems to be impossible because by entering the VM I loose the host's workspace switcher. Is there a nifty workspace switcher program that runs inside the VM and is able to switch workspaces of the host machine? Edit in light of Frank Thomas' answer, can we configure VirtualBox (or VMware) to not send certain key combinations to the VM, but keep them to the host? Like Super+S. In that approach I would sadly have to miss the nice workspace switcher icon in the guest OS, but that's OK if at least the keyboard trick would work.

• 12.04 server on home network

  - by dustin mantei

  I need advice to help me with a server install, I'm new to ubuntu and linux in general. I have 6 systems in my house, 5 being windows 7 and this laptop that I am typing on is Linux mint 13 Maya. Question is, my wife will not transition to anything. She is stuck in Gates-land. so, can I make a server with ubuntu 12.04 (burnt disc image last night) so that all systems in my home can access and my mother-in-law in another state can also access with a username? That would be awesome and it may convince the war dept (my wife) to change all the systems in my house to ubuntu/linux. Sorry this is so long winded, but all the questions I have seen on this forum don't answer it completely.

• Text box select issue

  - by Kent Boogaart

  I have this issue where the entire text in text boxes is selected whilst I'm typing in it. For example, in FireFox search box I'd try to type "foo" but end up with "o" because I managed to type "fo" before everything was selected, and then typed "o" which replaced the "fo". When it happens, it is incessant - not just a one-off. But it doesn't happen all the time, and I haven't managed to figure out what causes it to start and stop. Is this a known problem with an easy solution? EDIT: this has nothing to do with touchpad. I get this occasionally even on a machine without one. I can usually rectify the issue just be alt-tabbing about a few times.

• Which is the best non-java, dynamic, programming language to build attractive GUIs?

  - by VeeKay

  I am well acquainted with java and groovy but somehow I am not intrigued by the performance or looks of swing based applications that are developed on the same. So I want to learn and know about THE best alternate dynamic programming language (coz I am looking for little bit of luxury while writing code by not willing to fiddle with pointers, memory handling, static typing difficulties etc) to develop attractive cross platform GUIs. To be precise, when I say attractive I mean support for elegant translucent windows and nicer components (not the flashy adobe stuff). Can you please suggest me a programming language that manages to fit into this?

• Dynamic website SEO development

  - by Pankaj Upadhyay

  I made a website which stayed online for 6 months. During that period the search results for the site were not at all good. Even typing the domain name yielded just two or three category result. Now, I have taken the site down for total redevelopment and redesign. The aim of this question is to know the basics for SEO to be done while redesigning the site. My site will be in ASP.NET MVC 3 and will have main categories, sub categories and sub-sub if any. Then there will be products in those categories. All the data will come from MSSQL DB. Please tell me just the basics required for a dynamic website during development. I want to ensure that google and other engines index all the pages of my site including products or whatever.

• Covering Yourself For Copyrighted Materials [on hold]

  - by user3177012

  I was thinking about developing a small community website where people of a certain profession can register and post their own blogs (Which includes an optional photo). I then got to thinking about how people might use this and the fact that if they are given the option to add a photo, they might be likely to use one that they simply find on Google, another social network or even an existing online blog/magazine article. So how do I cover myself from getting a fine slapped on me and to make it purely the fault of the individual uploader? I plan on having an option where the user can credit a photo by typing in the original photographers name & web link (optional) and to make them tick a check box stating that the post is their own content and that they have permission to use any images but is that enough to cover myself? How do other sites do it?

• My computer boots up with Ubuntu: How can I tell what's on my hard disk?

  - by Larry Harson

  I've acquired an old laptop (Acer TravelMate 4050 with an Italian keyboard) that boots up with the following options: Ubuntu, with Linux 3.0.0-12-generic Ubuntu, with Linux 3.0.0-12-generic (recovery mode) Memory test (memtest86+) Memory test (memtest86+, serial console 115200) When I choose the first option, the screen just goes blank with a flashing cursor. But I can go into grub command mode by typing 'c'. Now, I want to know what operating system is installed, and the files stored on my computer, so how do I do this? What can I do to maximise the use of this computer in its current state?

• Trouble installing 12.04 from cd, blank screen with cursor

  - by Master Morality

  I should preface this with saying that this is not my first rodeo. I started playing with Linux in 1999 (Red Hat) and I'm currently typing this on a ThinkPad running 12.04... When I put in the live cd, I boots, and I can get to the option menu to decide whether to install/run etc, but at any point beyond that I get only a single caret. I can type stuff in, but it goes no where. I've tried the usual stuff like running with nomodeset (thinking it was the intel HD400 graphics, but it is integrated graphics...) here is the setup: ASUS p8z77 pro (with the Atheros AR9485 wifi supposedly, but I'm not that far yet) i7 3370k 8gig X 2 G.Skill Crucial M4 (256 gig) LG Super-multi DVD re-writer no video card UPDATE: I though may be it was a bad image on the CD, so I downloaded another iso, and used a USB disk. now it boots to a blank screen. I can see the "press any key to get options" screen, but after that, it just goes to a blank screen.

  - by Suhail cholassery

  I have lot about Flareget download manager and I wanted to install it in my computer. I visted the website and dowloaded the the file flareGet_1.0-1(beta)_deb_rpm.tar.gz and saved it in the location /home/suhailcholassery/Download/flareGet_1.0-1(beta)_deb_rpm.tar.gz. The thing is that I am new to Ubuntu and don't know how to install it. I tried typing the following command in terminal as per the readme's instruction enclosed in file. yum install flareGet-1.0-1.i386.rpm, but the reply was the following: You need to be root to perform this command. And I don't know how that is to be done. Isn't there any simpler way for installing this package?

• Left and right keys acting crazy on Ubuntu 10.10 Netbook Remix?

  - by Stephanie

  Hi guys, I just installed Ubuntu 10.10 Netbook Remix on my HP Mini 1000. Everything worked fine right up until I tried typing - apparently the left and right arrow keys on my keyboard are uncontrollable. Everything I type ends up looking messed up because the left and right keys keep automatically inserting themselves into everything I type. This also happens when I click on, say, "File" on Firefox. It starts rotating between all the different menu options even though I'm not pressing anything on the keyboard. Does anyone have any idea what's going on? Is this a problem with the keyboard itself?

• PC is randomly shutting off

  - by Bobby

  I have a PC which is randomly shutting off (the hard way, like someone pulled the plug). It's no heat problem, because this can happen after 2 minutes of operation or after 4 hours and I checked the temperature. It's also no problem of the operation system, because it will also do that while in BIOS. If it happens once, you can be sure that it will happen within the next hour another two or three times, and then it works again for over a week or even longer. Possible causes I've thought about so far are: Voltage Fluctuation Loose contact (already replugged all cables within the PC, no luck) Faulty PSU Maybe someone has more ideas to this? P.s.: I don't have the hardware specs with me right now, I'll post them as soon as I get them.

• No audio in Google Chrome

  - by Z9iT

  I started with Ubuntu 12.04 Minimal. Then installed only 3 utils sudo apt-get install xorg xinit google-chrome-stable alsa-base alsa-utils alsa-oss I have added google-chrome to .xinitrc file. Used sudo alsamixer to unmute everything using M. Also I am able to hear sound when I run this independently in a terminal sudo aplay /usr/share/sounds/alsa/Front_Center.wav However Google Chrome is not giving any sound output be it on youtube or the same file (/usr/share/sounds/alsa/Front_Center.wav) opened by browsing in chrome. UPDATE : the moment i install some Desktop (display) Manager like gnome or lxde and launch chrome then, the audio is perfect success. However if i kill the xsession and the desktop manager (lxde) AND then start with loading only the chrome (without DM) then again i loose the sound. This makes me wonder that there is something which is not allowing the sound to be loaded into chrome directly, but once the session like lxde loads, then it works flawless. I am thinking that i should rather ask, how to authorize google-chrome to use sound software? Miscellaneous : I am surprised to know that I cannot start google-chrome by sudo command (it asks to be a normal user) && that i cannot start alsamixer as a normal user (i must use sudo alsamixer ) May someone please help what i need to do so that google chrome speaks????

• pointer jumping about Lubuntu 12.04

  - by Gary Kirkpatrick

  Using 12.04 on a Samsung NC110. If I disable Touchpad, the cursor does not jump about while typing. This is very very annoying. Tried this tutorial, but this does not help. The problem occurs even when my fingers are well away from the Touchpad. I wonder if another key or key combination causes this problem? I sure could use some help on this. I have had this problem with various versions of Ubuntu and now Lubuntu.

• Steam not displaying text on wine 1.5 running on Ubuntu 12.04

  - by Jscags

  Hello fellow dwellers of askubuntu, as the title says I'm having difficulties with getting Steam to run properly. I think I have the solution but I am pretty incompetent with Ubuntu (just started using it the other day) so a step by step process would be unbelievably appreciated! Here are the links to what I think possible solutions are: [1] https://bbs.archlinux.org/viewtopic.php?id=146223 [2] http://bugs.winehq.org/show_bug.cgi?id=31374 I've tried googling how to preform the solutions such as changing the alias/script for steam (no idea what that is) to -no-dwrite or launching with wine Steam.exe -no-dwrite. The dwrite seems to be the issue in all this but I can't for the life of me figure out how to do anything about it. Any useful input is what I'm hoping for but for the brave soul who feels like typing a bit more, perhaps a step-by-step list of instructions starting from downloading Steam off the official website, would be my saving grace. If there is any more info you guys need let me know and I'll of course be happy to oblige!
