• Can't Make Changes via FTP on my Ubuntu Server

  - by Rev

  I'm very new to server management, I literally just set this up for the first time a couple weeks ago, no idea what I'm doing. In order to allow WordPress to run updates, apparently everything needs to be owned by www-data, but if everything is owned by www-data, I can't FTP with the user revxx14. When I try, I can't make any changes (deletions, additions, updating files, nothing. I get permission denied errors across the board). Is there a way to give my user the same permissions as www-data, so that I'll be able to keep www-data the owner, but still be able to make changes via FTP? Thanks.

• How can I prevent another site from trying to phish my customers by cloning the look and feel of my site?

  - by NextStep

  I have a site hosted on Godaddy. Recently, another site that I don't control has copied the look and feel of my site. They look exactly like my site, except the domains are different.. Godaddy's staff said there is nothing they can do to prevent that site cloning the look and feel of my site. Is there anything I can do to stop another site from effectively cloning my site? How can I keep my customers from being duped by this?

• .xprofile isn't enough

  - by BrianXP7

  I've been trying to find a solution on how to change the screen resolution on the login screen and other users. .xprofile will only affect my account. I've been searching for a few months but I got nothing. Please help. It would be easier if the "Default Resolution" was still there in the monitors settings. Plus, I'm afraid of editing the xorg.conf. Last time was ugly... My specs: HP dc5000 Small Form Factor Ubuntu 11.10 Oneiric Ocelot i386 Intel Pentium 4 2.40 GHz Intel 82865g x86/MMX/SSE2 Integrated Graphics (Standard Experience, OpenGL 1.3 and Runs Unity 3D :P) SoundMax Integrated Audio Card Broadcomm Integrated Ethernet 994.1 MiB RAM 38.3 GB HDD Acer X203H (Maximum Resolution 1600x900)

• Ubuntu crashed during the update to 12.04, not I can't recover my files, help please

  - by mrah

  I'm pretty new to Linux and I've only installed Ubuntu as I couldn't afford to buy Windows, worked well and I liked it. But I chose to upgrade it to the newest version after a prompt. The update froze and the machine was unresponsive which forced me to hard reboot it. Now nothing seems to load and I've reached my wits end (mainly cos I'm lost in all the command lines). I've decided to try and recover my data from the hard drive, only two folders, by selecting the try Ubuntu option when I insert the OS CD into the machine. The problem I'm experiencing now is it won't let me copy my folders, I get a 'The folder contents could not be displayed. You do not have the permissions necessary to view the contents of "folder_name".' Does anyone know how I can recover this data?

• Any good site that teaches C++?

  - by Shinmaru

  I am searching for any good site that teaches C++, that can explain most to all things about it(general) and has a decent active community. About Me: I am new to programming(knows nothing of it, so please bare with me), I have only learned(to a very basic form) LUA scripting Language, so yes I am your complete newbie. I got interested in programming, from scripting in LUA, so you can say it was my small stepping stone, One would basically take a course in college, but not everyone is well funded for that and I can't buy books for the same said reason(yes I'm somewhat poor, only money for essentials and bills), I'm not trying to get sympathy, just stating my conditions. and Please, something in between the lines of 'Programming for Dummies'(I'm not the brightest crayon in the box), I know this will not be easy, but your help will be most appreciated. I would learn for either Windows and/or Linux/Unix. I use both. Site(s) I know: Cplusplus.org(quite inactive and tutorials are a little for the programming savvy.

• Installing programs from a download

  - by user7274

  Hello, my name is Anthony and I'm new to Ubuntu and any other Linux OS for that matter. My question concerns downloading a program, and then installing it. The program is called Remotedroid, it lets you use your phone as a wireless keyboard and mouse. I'm use to windows automatically starting setup upon download and cant figure out how to initiate the install in Ubuntu. The programs website says its compatible with Linux OS and the readme file says to just click the extension remotedroidserver.jar to use, but it wont work and none of the files do anything. I've unzipped all the files and my Java is all up to date as far as i know, I think. I'm just not getting how to run a setup in Ubuntu. I looked around this site for the answer but came up with nothing so if someone could maybe offer some insight I would be grateful. Thank you.

• Syanptics Touchpad Won't Re-enable

  - by user71607

  I disabled my Synaptics touchpad while a key on my keyboard and now I can't get it to work again. When I press that key again it says the touchpad turns back on but will not work at all. Rebooting doesn't help, and I tried installing touchpad-indicator but when I try to enable from there it says that it enables, but the icon remains like it's disabled. The odd thing is that it works on the lock screen so I know the drivers aren't messed up, it's just a setting. Also, the touchpad works on guest mode but still nothing on my account. I tried using gconf to set the touchpad_enable to true and it worked, it sure set it. Doesn't make a difference though, my touchpad is still useless. Terminal commands I've used: gconftool-2 --set --type boolean /desktop/gnome/peripherals/touchpad/touchpad_enabled true synclient Touchpadoff=0 modprobe psmouse

• Moving from an IT department to a proper technology company

  - by user2434

  I have been working with Java/web applications in an IT department of a retail company. As much as work goes, there is nothing much to say. Fixing couple of if/else loops, writing some simple business logic etc., is all what I have been doing. Having said that, I feel I have a good technical knowledge, and I am willing to move to companies like Microsoft/Google/Amazon etc., [I want to work in these places, because I feel I am a technical guy, and I am working in a place where most people freak out when the words like 'algorithm' are heard] I can of course prepare algorithms/computer science fundamentals etc.,(I hold a 4 year degree in computer science program) but beyond that, will my experience hold against me ? I doubt I'll even get a call from them seeing my work experience. What kind of questions(apart from the algorithm types) can I expect ?

• Matrix camera, movement concept

  - by NoFace

  I was talking to some guy. He said that my movement concept in game is bad. When left or right arrow is pressed I'm scrolling background what makes you feel that player is moving (player's X remains same). So... he told me something about matrix view. I should create all walls and platforms static and scroll only the camera and move player's rectangle. I did a little research in Google, but nothing found. Can you tell me anything about it? How to start? Maybe links, books and resources? My programming language is Java (2d). Thank you!

• .Museum Domain Name Registrar

  - by mmundiff

  Anyone know of a reputable domain name company which deals in .museum domain names? Previously we had used DomainBank without much issue. DomainBank was bought by Dotster and am having nothing but trouble since the switch. Currently the website has been down for two days and it is a MAJOR issue. I know .museum is a seldom used domain name but I really need to switch to a reputable company. GoDaddy doesn't work with them unfortunately. Anyone know of a good company that does?

• What is the difference from the push and pull development models?

  - by michelpm

  I was reading Extreme Programming Explained, Second Edition and in the chapter 11 "The Theory of Constraints" the authors talk about the old and obsolete "push" development model and the XP way, the "pull" development model. It looks like a quite important concept, but it takes only a very small paragraph and two images that are mere illustrations of the "waterfall" and iterative process, nothing specific about these models except by the image caption. I searched and it doesn't go any further about it in the rest of the book. I couldn't find any further explanations or discussions about it in the Internet either. If the only difference about those is that one is "waterfall" and the other is iterative, them why push and why pull? Does anyone understand what is really the difference between those two and give some good examples?

• How do you get users to rank their software enhancement needs?

  - by Lego Stormtroopr

  I've inherited a legacy software system, and have been tasked with performing usability and system upgrades. While there's nothing bad with the system, from discussions with the users, there are "small" usabilty issues that need to be addressed. At this stage I'm the lone developer on this system, and apart from testing I don't use the system at all, so its difficult for me to know what issues may exist or are percieved to exist. I'm going to have some time to speak with them all and discuss what they percieve to be good/bad or indifferent about the system. Since its essentially just me for the time being my time is limit. So I was considering asking them to imagine that I'd only be able to do one change, have them all write privately what they'd want that one change to be, and then helping them rank those, but I'm hoping for other tips as well. What techniques exist for getting users to explain their wants, needs, and requirements, while also having them rank them by importance or desirability?

• how do I upload photos from shotwell?

  - by Mags

  I only started using Ubuntu a couple months ago. I've been able to get pictures from my camera onto the machine. The system is very different for me and I'm trying to work it out on my own, but I have a homework assignment that requires me to upload JPG files of photos I take and I'm having a problem. When I click the button on the page to choose a file, I go into the different photo files and nothing shows up, but the screen where files would be turns a very faint orange, just a tint. I've tried putting the named photos on my desktop, but the upload screen doesn't recognize it at all. How can I use this software to upload my pictures? Thanks.

• Limiting what resumes computer from suspend

  - by user1399195

  I'm having a ton of trouble getting Suspend to work with my laptop. I want to start using Ubuntu but this is a pretty important aspect since I take my laptop with me everywhere. Anyways, I wanted to narrow down the possible problem with my laptop. What happens is that when I suspend my computer, within seconds, it just boots back up. I have changed /proc/acpi/wakeup to where everything is disabled but that did nothing. Is there a way where I can disable every feature from waking up the laptop except the power button?

• Ubuntu 12.04 VM goes dead unexpectedly

  - by pyInTheSky

  I'm not a super savvy super user, so I'm not sure what to look for. I have a vm running 12.04. It runs fine, and then just dies (no ping, no ssh). When I log into vmwaresphere, I see the vm still 'UP', but the console gives me a response-less black screen. This lead me to believe that Ubuntu was going into some sort of sleep/hibernate state. I double checked the power settings and found nothing out of the ordinary, so now I'm stuck on how to fix the problem. There are 5-7 (centos-5.8 & 6) machines running on the same server/vm setup with no problems at all. thanks.

• 12.04 + Alienware M11x R2 + Bumblebee 3.0 = low resolution only

  - by user89171

  I had a fresh install of Ubuntu 12.04 on my Alienware M11x, and it worked with the native monitor resolution of 1366x768. In trying to get the Optimus chipset working, I installed Bumblebee 3.0. Now, I am only offered 640x480 for my monitor resolution. Graphically, Unity 3D appears to be working now, instead of the Unity 2D I had before, so something went right, but I don't know how I can get it to offer me any higher resolutions than 640x480. I've looked up many pages that address this topic, but nothing that I've seen suggested has worked. sudo add-apt-repository ppa:bumblebee/stable sudo apt-get update sudo apt-get install bumblebee-nvidia was the latest thing I tried. I've tried some variants of this, I've been sure to uninstall nvidia drivers prior to reinstalling Bumblebee and various video drivers. Does anyone have any clue as to how I can get back to native resolution?

• Multiple copies of JBoss acting as one? [migrated]

  - by scphantm

  I have a few ideas how to solve the problem, but one question about jboss clustering. Please, keep in mind these applications were written very poorly, that is why they require so much memory and there is nothing i can do about that right now. So, I have clustered applications on Jboss where the application was small enough to run on one box. Meaning that one machine could handle the load. But, the current problem is that i have been asked to run several systems on the same environment. Our machines are virtuals and due to limited hardware, are restricted to 8 GB RAM, which gives jboss about 7GB to itself. Unfortunately, that isn't enough to run the group of applications. Im constantly getting heap errors and crashes. If i cluster 2 or 3 jboss instances together, can i run applications that consume more resources than a single box can handle?

• Desktop not showing after playing with compiz

  - by Mark

  Having successfully installed Ubuntu 11.04 I decided to look into improving look and feel of the unity desktop. I could find no option to introduce any nice effects with the standard install, but a google session suggested Compiz would do the job. I installed this and selected the "Wobbly windows" option and this worked fine. After a while I thought I'd try some of the other available effects (can't remember which but may have been cube desktop) but this resulted in no windows showing at all. I now have just blank wall paper with no icons or menus. There are no error messages and right clicking the desktop produces a small context menu but nothing else. Rebooting brings me back to a blank desktop with just wallpaper. I do not know where to start.

• Juniper setup on 12.04

  - by Lauran

  I have a laptop with Windows XP and Ubuntu 12.04 (32 bits). Until now, I used Windows XP to connect to a Juniper VPN but now I'd like to try it with Linux. I read the mad scientist walkthrough (including the sun java part) but I can't run the setup. I get the popup that ask me if I'm sure I want to run the applet but then, nothing. mad-scientist says it's probably a C runtime lib problem and suggests to use his script with -nojava but he doesn't say how to install Network Connect in the first place. Any idea? Thanks for any suggestion! Laurian PS: I have: Ubuntu 12.04 32bits Java from Sun 1.6.0.32 Firefox 12 xterm (I think it was suggested somehwere)

• 12.04 gnome shell broken after updates

  I'm running Ubuntu 12.04, and using gnome shell. I've had my machine running for the last few days, and I've been installing updates as the update manager bugs me. I just rebooted, and now gnome won't start. I can use gnome classic and unity, but gnome 3 isn't working at all. When I log in, the screen is black for maybe 20 seconds, but the cursor shows. Then, my wallpaper, but nothing else shows up. I can get a terminal with ctrl+alt+t, and I tried to run gnome-shell, but it segfaulted.

• .NET - Where can I start? [closed]

  - by mustang2009cobra

  I'm a moderately experienced developer with experience developing using a variety of languages. I've done C++, Java, PHP, Javascript, and several other languages. I remember the Java dev stack being rather difficult to dive into, but it's nothing like the endless sea of the .NET framework. I'd like to become experienced in .NET development, as many dev shops are microsoft-centric. But I'm a little unsure as to where the best place to start is. As I already know a bunch of programming languages, I don't really need resources that will help me learn C# or any of the .NET languages as much as I need to learn the development stack, APIs, etc. Any suggestions on the best way to start learning .NET development?

• HTML5 apps

  Right now nobody’s interested in a mobile solution that does not contain the words “iPhone” and “app” and that is not submitted to a closed environment where it competes with approximately 2,437 similar mobile solutions.Compared to the current crop of mobile clients and developers, lemmings marching off a cliff follow a solid, sensible strategy. Startling them out of this obsession requires nothing short of a new buzzword.Therefore I’d like to re-brand standards-based mobile websites and applications,...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?
