  • How do I get long command lines to wrap to the next line?

    - by BrianH
    Edit It was my .bashrc file. I've copied the same profile from machine to machine, and I used special characters in my $PS1 that are somehow throwing it off. I'm now sticking with the standard bash variables for my $PS1. Thanks to @ændrük for the tip on the .bashrc! ...End Edit... Something I have noticed in Ubuntu for a long time that has been frustrating to me is when I am typing a command at the command line that gets longer (wider) than the terminal width, instead of wrapping to a new line, it goes back to column 1 on the same line and starts over-writing the beginning of my command line. (It doesn't actually overwrite the actual command, but visually, it is overwriting the text that was displayed). It's hard to explain without seeing it, but let's say my terminal was 20 characters wide (Mine is more like 120 characters - but for the sake of an example), and I want to echo the English alphabet. What I type is this: echo abcdefghijklmnopqrstuvwxyz But what my terminal looks like before I hit the key is: pqrstuvwxyzghijklmno When I hit enter, it echos abcdefghijklmnopqrstuvwxyz so I know the command was received properly. It just wrapped my typing after the "o" and started over on the same line. What I would expect to happen, if I typed this command in on a terminal that was only 20 characters wide would be this: echo abcdefghijklmno pqrstuvwxyz Background: I am using bash as my shell, and I have this line in my ~/.bashrc: set -o vi to be able to navigate the command line with VI commands. I am currently using Ubuntu 10.10 server, and connecting to the server with Putty. In any other environment I have worked in, if I type a long command line, it will add a new line underneath the line I am working on when my command gets longer than the terminal width and when I keep typing I can see my command on 2 different lines. But for as long as I can remember using Ubuntu, my long commands only occupy 1 line. This also happens when I am going back to previous commands in the history (I hit Esc, then 'K' to go back to previous commands) - when I get to a previous command that was longer than the terminal width, the command line gets mangled and I cannot tell where I am at in the command. The only work-around I have found to see the entire long command is to hit "Esc-V", which opens up the current command in a VI editor. I don't think I have anything odd in my .bashrc file. I commented out the "set -o vi" line, and I still had the problem. I downloaded a fresh copy of Putty and didn't make any changes to the configuration - I just typed in my host name to connect, and I still have the problem, so I don't think it's anything with Putty (unless I need to make some config changes) Has anyone else had this problem, and can anyone think of how to fix it? Thanks in advance! Brian

  • Real-time chat in Ruby on Rails

    - by Skydreamer
    First, I'm sorry because I know this question has been asked many times but I'm still looking forward to finding the answer to my problem. I'd want to implement a Real-time chat for my Rails app but I can't really host the server which handles the sockets. I've tried Faye but it needs a server. I've also heard of pusher but it's limited to 20 users at a time on the chat and I can't really be sure they won't be more. I've thought of irc but I think I can't really embed it into a rails app, maybe it needs sockets... So here's my problem, can I implement a real-time chat without owning a server ? What can you advice me ? Thank you for your answers.

  • 12.04 scanner works fine as super-user but is not recognised as a normal user

    - by Eugénio Outeiro
    I have an all-in-one printer Epson SX130, wich I have just tried to install. I got the printer working with no problem, but I couldn't set the scanner up. I have had another all-in-one printer before (Brother DCP-125C), and had just the same problem, so I decided to try the same trick I used to do then, running the scanning program as super-user: $sudo simple-scan and $ sudo xsane Once again, it worked just fine, and I could use the scanner. Anyhow, this solution is a little annoying, because I also have to change the permissions to the files I get scanning like this. I have been searching the internet for solutions and got to know this must have something to do with user groups permissions, but couldn't find a satisfying solution. Is there anyone with an idea? Thank you in advance.

  • Slow gvfs Samba Performance

    - by Wolfgang
    if I use/acces a Samba Share using Nautilus or manually using "gvfs-mount smb://SERVER-IP/Share" I get a poor Performance, only about 7 mb/s on my 100 Mbit Network. If I access the same Share on Windows I get Fullspeed 100 Mbit (About 11 mb/s), also if I mount using sudo mount -t cifs //SERVER-IP/Share /mountpount which uses cifs instead of gvfs I get fullspeed too, so can anyone tell me if there is a Performance Problem/Bug in gvfs or how gvfs is using SMB Shares differerently ? I tested read Perfomance (From my Network Samba Share) with multiples files and always, the cifs-Version is fullspeed and the GVFS-Version has some mb/s less. After some research I found some tips to optimize the Samba Settings of my Ubuntu Installation and some network tuning tips, but as the CIFS mounted share gets the full Network Speed I don't believe its that kind of problem.

  • Redirecting non existing post to homepage; is that good for SEO?

    - by BlackEagle
    I am checking my website out on Google Webmasters and I am seeing an astonishing 5000 links that could not be found by Google's Crawlers. That's normal, because my website is built in a manner that users can drop their own things, which also lead to 404 pages. Not a problem at all if I can find a workaround of course... So my question is: what if I made a function or a mod rewrite that will check if the link exists (a post for example) and if not, it will redirect it to the home page. Is this good for SEO? Will Google see this as 'link found'? How do I have to look at this problem?

  • Correct way to handle path-finding collision matrix

    - by Xander Lamkins
    Here is an example of me utilizing path finding. The red grid represents the grid utilized by my A* library to locate a distance. This picture is only an example, currently it is all calculated on the 1x1 pixel level (pretty darn laggy). I want to make it so that the farther I click, the less accurate it will be (split the map into larger grid pieces). Edit: as mentioned by Eric, this is not a required game mechanic. I am perfectly fine with any method that allows me to make this accurate while still fast. This isn't the really the topic of this question though. The problem I have is, my current library uses a two dimensional grid of integers. The higher the number in a cell, the more resistance for that grid tile. Currently I'm setting all unwalkable spots to Integer Max. Here is an example of what I want: I'm just not sure how I should set up the arrays of integers of the grid. Every time an element is added/removed to/from the game, it's collision details are updated in the table. Here is a picture of what the map looks like on my collision layer: I probably shouldn't be creating new arrays every time I have to do a path find because my game needs to support tons of PF at the same time. Should I have multiple arrays that are all updated when the dynamic elements are updated (a building is built/a building is destroyed). The problem I see with this is that it will probably make the creation and destruction of buildings a little more laggy than I would want because it would be setting the collision grid for each built in accuracy level. I would also have to add more/remove some arrays if I ever in the future changed the map size. Should I generate the new array based on an accuracy value every time I need to PF? The problem I see with this is that it will probably make any form of PF just as laggy because it will have to search through a MapWidth x MapHeight number of cells to shrink it all down. Or is there a better way? I'm certainly not the best at optimizing really anything. I've just started dealing with XNA so I'm not used to having optimization code really doing much of an affect until now... :( If you need code examples, please ask. I'll add it as an edit. EDIT: While this doesn't directly relate to the question, I figure the more information I provide, the better. To keep your units from moving as accurately to the players desired position, I've decided that once the unit PFs over to the less accurate grid piece, it will then PF on a more accurate level to the exact position requested.

  • Is it a bad practice to register sntsh.com if my name is Santosh?

    - by Santosh
    My name is Santosh but I can't register a santosh.com because it is already taken. Most extensions for Santosh are already taken. I was trying to register a domain with .sh extension but santo.sh would cost me very high and I can't afford ~$100 for just a personal domain and that's only for one year only. Now I am thinking that I should register a sntsh.com. But there is a problem, will sntsh.com over my name Santosh don't create a SEO problem? One more thing, that totally different from above topic. If I register a santosh.name domain which is not registered, won't it create copyright and any legal problems with other santosh domains?

  • Ubuntu 14.04 Notification incorrectly displayed

    - by xenolyse
    I have a problem with my notifications on Ubuntu 14.04 x64. The notifications are just plain text with a colored background, and are also strangely placed in the top left corner. I have no idea on how it changed. After one reboot it was just there.. Here is a picture of the problem in question.: As you can see the notification appear over the unified menu. How can I restore the original state of the notification bubble? Here are the settings in ~/.notify-osd slot-allocation = fixed bubble-expire-timeout = 10sec bubble-vertical-gap = 5px bubble-horizontal-gap = 5px bubble-corner-radius = 37,5% bubble-icon-size = 30px bubble-gauge-size = 6px bubble-width = 240px bubble-background-color = 131313 bubble-background-opacity = 90% text-margin-size = 10px text-title-size = 100% text-title-weight = bold text-title-color = ffffff text-title-opacity = 100% text-body-size = 90% text-body-weight = normal text-body-color = eaeaea text-body-opacity = 100% text-shadow-opacity = 100% If I check the org.freedesktop.Notifications.service(/usr/share/dbus-1/servies) it appears to use the correct one.

  • No app icons in menus

    - by Lyrositor
    I have enabled icons in menus, and most of them show up well (folder icons, file icons, save icons, etc.). But whenever an app tries to use an icon specific to itself, such as GIMP, it replaces that icon with the app icon, so that when I look at a menu in GIMP, I see most of the time just icons of GIMP's logo (that seems to be the only problem; the text is fine). I thought this was proper to GIMP, but I also noticed it happening on AbiWord. Thankfully, as I said, it's not for all icons. But it still bugs me. Why is it so? Here is a screenshot of a menu in GIMP: I am using Ubuntu 11.04 Natty Narwhal, with Unity desktop (the problem also occurs on the Classic desktop, if I remember correctly). EDIT: This does NOT occur on the Classic desktop; only in Unity.

  • Ubuntu 12.04 LTS x86_64 sound artifacts when scrolling with firefox

    - by Nh3xus
    I've been using Ubuntu since the 10.04 LTS version and i have a sound problem that still remain in my fresh install of the 12.04 LTS AMD64 version. This install has been performed by formatting the / partition and my documents were kept safe in the separated /home partition. The problem : When i listen to a audio or video source while browsing the web with Firefox, I have some sound artifacts when i'm scrolling and stops when i'm not doing it. This happens when i'm doing X11 related actions too, such as switching between virtuals desktops. Computer configuration of my laptop : - Ubuntu 12.04 LTS AMD64 - Plantronic USB Headphones - Intel HDA Audio sound card (laptop) with SigmaTel STAC9200 chip - AlsaMixer v 1.0.25 - Nvidia GeForce 7950 GTX with Nvidia 295.40 driver Any advices are welcome here :) Note : This is my first post on AskUbuntu.

  • Configuring keyboard input to eliminate unused diacritics

    - by David Cesarino
    I'd like to change the way diacritics work under Xubuntu. My problem My native language is pt-BR and my notebook has an american keyboard. Thus, I use ' and " followed by keys like u and c to achieve things like ú, ç and ü. It all works well. However, in the case of apostrophes and quotes, that creates a problem when I use ' followed by: letters that won't accept the acute accent ( ´ , ACUTE ACCENT -- 0x00B4) at all, like t; and letters that won't accept the acute in pt-BR, like r. In 1, ' with t does absolutely nothing. In 2, ' with r creates r (LATIN SMALL LETTER R WITH ACUTE -- 0x0155), which is used, afaik, for some eastern european languages like slovak. It isn't used in portuguese, just like ?, s, z, ?, ?, ?, n and all consonants (portuguese do not take diacritics in consonants). Question That said, is there a way to better support the portuguese-brazilian language using an american keyboard? It is very common here --- I actually prefer the american keyboard to our own, known as “ABNT”. Desired solution I'd like to deactivate unused diacritics, so case 2 would behave just like case 1. Additionally, if possible, I'd like case 1 to behave like it does under Windows. As an example, typing ' followed by t should write 't (acute followed by T) instead of doing nothing. About 2, in my humble opinion, doing nothing is counterproductive. I realize the behavior is reasonable according to logic ("there isn't t-acute, so please tell the computer to typeset apostrophe --- ', SPACE --- instead of acute). But from a human, practical point of view, I think it makes more sense (to me, at least). Additional comments I believe this also applies to spanish, french, italian and other western european latin languages. On the console (Ctrl+Alt+F?), case 1 is not a problem. I don't need to press space as apostrophes are automatically added. However, there, I'm unable to access cedilla (ç). Two completely different behaviors. If it's just a matter of customizing text config files (possibly creating a custom layout or whatever), I'd be glad to share my efforts. I just need guide on the "howto" part. Somehow Google only points me to the "enough" people (those who cope with the situation and think that it works "well enough"). And since I have definitely migrated to Linux/Xubuntu after years, I'd like to leave just as I like it (and I'm sure others as well). For example, if there is some kind of scripting or definition to tell the computer to do what I described, so be it.

  • Bootstrap 3.0.0: How to use data-slide-to outside of indicators?

    - by Griffin
    I am attempting to make a small gallery like the one shown below - I'm sure you've all seen them considering they are fairly common. When trying to make one using bootstrap I ran into a major problem. I can't seem to link the smaller bottom images to the larger top one that was when one of the smaller ones is clicked it changes to the selected image. I am attempting to use data-slide-to however it does not seem to work outside of the "carousel-indicators". I can't put it into the carousel indicators list because that moves the images up into the gallery (It may be possible to fix this with CSS but my attempts have been worthless). Does anyone know the problem? I've tried tags around each image that didn't seem to work then I tried divs. Still nothing. Things to note: I am using 3.0.0 All images are generated (if you haven't guessed already) Smaller images are separate from larger one (not auto scaled down)

Already install almost all packages about bluetooth, like blueman, bluez, gnome-bluetooth, bluetooth, etc.

  • Ubuntu 12.10 TTY console (Ctrl+Alt+F[1-6]) not working

    - by Vanessa Deagan
    I've been a Ubuntu user for some time now. I have a very annoying problem, I have no idea what causes it, and I haven't managed to find anything relevant after Googling like crazy. The problem is my TTY consoles are not working. Usually, these are activated using CTRL ALT F[1-6]. It was working when I was using the Nouveau drivers, but after installing the nVidia proprietary drivers, instead of getting a terminal console I get a strange monochrome pattern that slowly fades away. Does anyone know how to get CTRL + ALT + F[1-6] working again?

  • Dynamic MMap ran out of room when trying to sudo apt-get anything

    I was having an error in Update Manager that asks me to do a partial upgrade and it fails. Now I can't sudo apt-get install anything. I tried to fix it, and now I can't sudo apt-get anything. Every time, I get this output: Reading package lists... Error! E: Dynamic MMap ran out of room. Please increase the size of APT::Cache-Limit. Current value: 25165824.

  • Project Hamster notifications missing on upgrade to 12.04

    - by deshmukh
    I have upgraded from an almost default 11.10 install to 12.04. All went well and I can login, logout, etc. without any problem. One very interesting thing about the Project Hamster notifications, though. I have set Hamster to remind after every 27 mins. I do not get these notifications. However, if there is no activity set, I see the notification. In 11.10, I used to get both the notifications. What is wrong? How do I set it right? By the way, the notifications work quite well in Unity. But in Gnome, the problem continues.

  • Why should I not do a masters degree

    - by aurel
    I have left university on July 2010 where I studied web design (as we all know you learn more by your self but that’s not the issue at the moment). Since then I have not managed to find a job (apart from a one month work experience), from the way things are going, and by taking into account the fact that all my university friends are in the same situation, I don’t think that I am going to find a job soon (within the industry) Now as we all do, even though I don’t have a job, I am still working on personal projects and try to keep up to date (I don’t need a job or uni to do this) – but I am thinking, because there is not work available, would it be worth going back to uni for a master degree? I know I don’t need it and I know that is unlikely that I will learn anything important, as I believe in self learning, and in most cases it is a lot more effective (but I have to say I don’t mind going back to school) The only reason I am thinking of doing the master is, (and this is where I need your help): If it takes me a year to get a job, then on the interview, would the employer think “what the hell did this guy do since he left university” – now if I go to university that would solve this problem. Or I’m I making up a problem that does not exist Plus, I know that employers need examples of sites that I have been working on, at the moment I only have 3 (as when working on personal projects, where their is not time limit I tend drag things in order to get them perfect, and they never get perfect) – so by going back to uni, then this problem maybe solved I said all this as I have read a lot about the fact that you don’t need to have a masters degree to work on web design market (and I totally agree) but considering my concern, the question is should I do a masters course to avoid just spending hours in my room working and learning in my own (but that it would be hard to convince employers that I was really learning in my room) Maybe because I’m still young age 22 not that old anyway :), but I don’t have the “dream” of being rich, so if I were to tell the truth I don’t really care of the fact that I don’t have a job (at the moment), because regardless, I am working on what I love every day, but I know that in the future when I will need the job I may find it harder to get one, if I neglect doing so now Every time I ask a question that I’m not sure about, I keep going on and on, but I really hope you get what I am trying to get across. By the way the course that I am looking at for a masters says that it would teach me how to do these: e-commerce e-government e-science e-learning I don’t know any of them, a part from e-commerce Thanks

  • How to choose a new technology for mastering and not lose sense of reality and practicality?

    - by Eyewan
    How to choose the right next step in learning programming and mastering new technologies? I have experience with WinForms applications in C# .NET. Next what I see as a good area of expanding the knowledge is ASP.NET. Language I already know, C #, so I think there is now more a matter of mastering new technologies. Also I have interest in WPF. Perhaps the best is to work on ASP.NET and WPF at the same time. Sometimes the problem is when we do not have motivation, but also known to become a problem when we want to much :) How to choose a new technology for mastering and not lose sense of reality and practicality?
