• Lending epub files for limited time to users

  - by JP Hellemons

  I am looking for components to build a digital library who lends people epub (ebooks) for about a week. It's like a digital version of the offline old public library. Now I have found several flash (pdf) file streaming solutions. But that would require an active internet link. And like the public library, you are able to take your books to the beach or pool on holiday abroad where you have no connection. So streaming is no option. The other file restriction method I have found was DRM, but that would require a really expensive license of Adobe Content Server 4 which is not suitable for my little hobby project. But it seems that adobe content server and Adobe Digital Editions is the only option at the moment. Or are there open source alternatives?

• Firefox, Chrome, and Flash on Ubuntu

  - by Zimmer

  Ok I have recently run into some problems and was hoping you guys could help; 1) On Chrome sometimes when I play a video (even on Youtube) the audio won't work (yet other apps audio will work) but after pressing the play button (pausing and unpausing the video) it finally works but if I pause the video and click play it goes back to not working until I re-do that process. 2) When I go to play videos in firefox or go to grooveshark it says I don't have flash; but I do and when I go to install flash it says I have the LAST version for linux but flash works on Chrome fine (well except the audio problem above which annoys me to no end!)

• RewriteRule not working at server level?

  - by Alexis Wilke

  I wanted to forbid some robots from doing certain things to my websites and decided to add a RewriteRule for that purpose. The rule works when put in one of my <VirtualHost *:80> tag and looks like this: RewriteEngine On RewriteCond %{HTTP_USER_AGENT} libwww-perl RewriteCond %{REQUEST_METHOD} POST RewriteRule . - [F,L] However, I wanted to apply that to all my websites instead of just one of them. So with the newest version of Apache2 settings, I decided to put that code in the security.conf file. This file is defined under /etc/apache2/conf-available/... (and yes, I have a softlink from the /etc/apache2/conf-enabled/... directory.) However, if the definition is only in the conf-available/security.conf files, it somehow gets ignored. From the documentation, it says that these Rewrite* commands all work at server level! Any idea of what I would be missing?

• Release build vs nightly build

  - by Tuomas Hietanen

  Hi! A typical solution is to have a CI (Continuous Integration) build running on a build server: It will analyze the source code, make build (in debug) and run tests, measure test coverage, etc. Now, another build type usually known is "Nightly build": do slow stuff like create code documents, make a setup package, deploy to test environment, and run automatic (smoke or acceptance) tests against the test environment, etc. Now, the question: Is it better to have a third separate "Release build" as release build? Or do "Nightly build" in release mode and use it as a release? What are you using in your company? (The release build should also add some kind of tag to source control of potential product version.)

• OOD: All classes at bottom of hierarchy contain the same field

  - by My Head Hurts

  I am creating a class diagram for what I thought was a fairly simple problem. However, when I get to the bottom of the hierarchy, all of the classes only contain one field and it is the same one. This to me looks very wrong, but this field does not belong in any of the parent classes. I was wondering if there are any suggested design patterns in a situation like this? A simplified version of the class diagram can be found below. Note, fields named differently cannot belong to any other class +------------------+ | ObjectA | |------------------| | String one | | String two | | | +---------+--------+ | +---------------+----------------+ | | +--------|--------+ +--------|--------+ | ObjectAA | | ObjectAB | |-----------------| |-----------------| | String three | | String four | | | | | +--------+--------+ +--------+--------+ | | | | +--------|--------+ +--------|--------+ | ObjectAAA | | ObjectABA | |-----------------| |-----------------| | String five | | String five | | | | | +-----------------+ +-----------------+ ASCII tables drawn using http://www.asciiflow.com/

• Software Life-cycle of Hacking

  - by David Kaczynski

  At my local university, there is a small student computing club of about 20 students. The club has several small teams with specific areas of focus, such as mobile development, robotics, game development, and hacking / security. I am introducing some basic agile development concepts to a couple of the teams, such as user stories, estimating complexity of tasks, and continuous integration for version control and automated builds/testing. I am familiar with some basic development life-cycles, such as waterfall, spiral, RUP, agile, etc., but I am wondering if there is such a thing as a software development life-cycle for hacking / breaching security. Surely, hackers are writing computer code, but what is the life-cycle of that code? I don't think that they would be too concerned with maintenance, as once the breach has been found and patched, the code that exploited that breach is useless. I imagine the life-cycle would be something like: Find gap in security Exploit gap in security Procure payload Utilize payload I propose the following questions: What kind of formal definitions (if any) are there for the development life-cycle of software when the purpose of the product is to breach security?

• Problem with gnome-shell-extensions-user-theme

  - by sodiumnitrate

  I'm trying to install themes with gnome tweak, and I need to install gnome-shell-extensions-user-theme because otherwise I cannot see the shell extensions tab. However, I cannot install shell extensions. I have tried to install by adding the PPA with the following: sudo add-apt-repository ppa:webupd8team/gnome3 Then, sudo apt-get update Finally, when I try to install: sudo apt-get install gnome-shell-extensions-user-theme It gives an error: The following packages have unmet dependencies: gnome-shell-extensions-user-theme : Depends: gnome-shell-extensions-common but it is not going to be installed E: Unable to correct problems, you have held broken packages. I am convinced that there is a problem with the package. So I went on and tried to install the extensions from the website: https://extensions.gnome.org/ But even though I use Firefox (15.0), I cannot see the "switch" that is being mentioned to install the extension. Maybe the version of Firefox is too new. Is there any workaround that you know of? (By the way, I use Ubuntu 12.04, freshly downloaded and installed.)

• Best practise for meta tags in various languages

  - by Jack Lockyer

  We have a global site, all hosted on one .com domain (www.website.com/en www.website.com/es www.website.com/pt www.website.com/ru etc) each language sub directory is identical to one another (apart from being in different languages) My question is, should I translate each meta keyword for each page or just use the english versions? e.g. English page about private jets : keyword "private jet" French version of exactly the same page : keyword "private jet" or "jet privé" If anyone knows whether language specific keywords carry any weight in search engines when the actual website is a .com and not a country specific domain, that would be really helpful! Thanks in advance!

• Why are the colors worse on Ubuntu 12.04 than on Windows 7 on my Sony Vaio E-Series?

  - by Simon Hoare

  The colours look "lacking" and ever slightly blueish and rather washed-out and lacking in dimension. Graphics are ok - this page for example looks fine - but if I view something like a news site with high quality photos, the experience is not optimal and is noticeably inferior to Windows 7. Oddly, when I install Ubuntu as a VM on VirtualBox in Windows, the colours look as I expect them to. It's only on my dual-boot version of Ubuntu that they look wrong (not Wubi, although a previous Wubi-based installation had the same problem). Now, I have the proprietary ATI driver and I can use amdcccle to get the colours closer to what they should be, but I can't seem to do anything about colour depth. The depth settings in Xorg are all 24. I tried changing all three mentions of 24 to 32 but was forced into safety mode. Fortunately, I remembered where I'd been tinkering and got the file set back to 24.

• Function inside .profile results in no log-in

  - by bioShark

  I've created a custom function in my .profile, and I've added right at the bottom, after my custom aliases : # custom functions function eclipse-gtk { cd ~/development/eclipse-juno ./eclipse_wb.sh & cd - } The function starts a custom version of my eclipse. After I've added it, because I didn't wanted to log-out/log-in, I've reloaded my profile with the command: . ~/.profile and then I've tested my function by calling eclipse-gtk and it worked without any issue. Today when I booted, I couldn't log in. After providing my password, in a few seconds I was back at the log-in screen. Dropping to command line using CTR + ALT + F1, I've commented out the function in my .profile and the log-in was possible without any issue. My question is, what did I do wrong when I wrote the function? And if there is something wrong, why did it work yesterday after reloading the profile. Thanks in advance. Using: Ubuntu 12.04

• What program should i use for Ludum Dare?

  - by mFontoura

  I want to participate for the first time on Ludum Dare, but i'm not confortable yet with a language to pick one for making a game on a weekend. So i was looking for a program 'gamemaker' style, just to make something for LD. I was going for Construct 2, but i use Linux and they don't have a linux version. So the alternative i use is Stencyl, witch is great and probably is what i'm going to use. However, i wanted to know if there is something similar and better for Linux. Also, if i get a computer with Win8, is it worth the trouble for Construct 2?

• genisoimage and exec bit preservation

  - by user92187

  Maybe I'm just not doing right, but I can't seem to get genisoimage to produce a UDF image and preserve the exec bit. $ genisoimage --version genisoimage 1.1.11 (Linux) $ echo "echo 'Hello world'" > script.sh $ chmod +x script.sh $ ./script.sh Hello world $ genisoimage -input-charset utf-8 -r -udf -volid minimal -o minimal.iso script.sh Total translation table size: 0 Total rockridge attributes bytes: 250 Total directory bytes: 0 Path table size(bytes): 10 Max brk space used 0 420 extents written (0 MB) $ mkdir mount $ sudo mount minimal.iso $PWD/mount -o ro,loop -t udf $ ls -l script.sh mount/script.sh -r--r--r-- 1 root root 19 Sep 21 18:40 mount/script.sh -rwxrwxr-x 1 kip kip 19 Sep 21 18:40 script.sh You'll note in the last command that script.sh was executable at the time it was injected into the image, but does not appear to be inside of the mounted image. Is this a bug in genisoimage, a problem with the way I am mounting the image, or a problem in my usage of genisoimage?

• Text Editor with SSH/Terminal/FTP/Putty combo for develeping in Rails on Windows

  - by Panoy

  I plan to learn Ruby on Rails and would like to code in my development box which runs on Windows XP. I have Ubuntu Server (forgot the version ;p) running as my web server with Rails installed on it. I have been considering using Vim as my text editor of choice in XP but would like to know any text editor and accompanying shell/FTP/Putty/SSH (or whatever you may call it) program that can access those files in my Ubuntu server. It is better if the shell can be called or is bundled inside the text editor. I would like to know your combinations (text editor + shell) and your experiences on it when you were able to develop your Rails projects on that combination. Cheers!

• How to boot load the kernel using EFI stub (efistub) loader?

  - by Pro Backup

  I have Ubuntu 14.04 running in UEFI mode as only operating system, no dual-boot here. The kernel version is 3.13.0-24-generic. There is an EFI partition. In this case the EFI partition is not at the default /dev/sda1 but at /dev/sda3 because I did actually convert BIOS mode to EFI mode. I have used the grub-efi-amd64 package, though that actually loads GRUB boot menu from UEFI firmware boot menu (UEFI boot loads \EFI\ubuntu\grubx64.efi). I want to skip that double boot menu loading step, and boot faster, directly from UEFI into the kernel. The Ubuntu kernels since 12.10 have "Kernel EFI stub loader" feature. I know I do need to copy the Ubuntu kernel to the EFI partition (possibly rename) and create an entry in UEFI boot menu (for instance using efibootmgr). Which exact terminal commands are necessary to do this?

• How to make background image black-and-white?

  - by Dmitri

  Are there any filters that would make background image to be displayed as black-and-white? What I mean, is this: i have a background image set via css using background: url(/image.png); But now I need to apply a filter so that an image is shown as black-white only. Ideally, I would like to also apply opacity to it. The effect I really trying to achieve is to have background image black/white and on hover over that span element the filter would be removed, revealing the color version. And of cause it has to work in FF, Chrome, IE Can someone help me?

• Why would I want to install node.js in my Rails Application?

  - by Crazy JIm

  Okay guys, I'm super confused. I thought node.js was a sever side framwork, basically the js version of Ruby's Rails or PHP's Zend. However, I'm having some difficulty with turbolinks, and it seems to be the way to fix it is through installing node.js I mean, I don't understand this at all. How can two frameworks work together like this? Also, it's not a gem (that REALLY would have confused me), you have to install node.js it onto your local machine by running (in the case of Ubuntu) sudo apt-get install nodejs Firstly, how does this totally separate framwork have any bearing on rails? Secondly, surely this isn't fixing the problem forever? When you specify a gem in your gemfile, the server knows what external libraries to install. How does the server know to install nodejs?

• How to design network protocols

  - by dandroid

  As a programmer, you work on your software design skills. You learn about things such as modularity and reusability and how you can achieve them in code. There's plenty of literature on the subject and engineers talk about it all the time. What about if you want to design network protocols? How do you judge that protocol X is badly designed while Y is well designed? (eg. in programming you are often pointed out to a well-written piece of code in order to learn from it - what is the equivalent for network protocols?) For example, suppose I want to design a P2P protocol similar to BitTorrent or I want to make a better version of the Socks protocol. How would I go about doing a good job on this? Thanks!

• I can't figure out how to run ubuntu .iso from thumbdrive?

  - by Judge Cole Stanley

  I downloaded Ubuntu 12.04.1 and I can't find a solid way to run it from the disk version of Ubuntu 11.04 for a clean install. I think the hard drive is messed up, or else I would install 11.04, but it won't work. So I wanna install 12.04.1 from a thumbdrive, so I can actually use this computer without using the demo and installing everything when it dies, or shuts off... Please help? I want to make it at least bootable from a thumbdrive, just so I can lightly browse the internet and what not... it doesn't have to be a hard install.

• TFS 2012 Upgrade and SQL Server - SharePoint - OS Requirements.

  - by Vishal

  Hello folks,Recently I was involved in Installation and Configuration of Team Foundation Server 2010 Farm for a client. A month after the installation and configuration was done and everything was working as it was supposed to, Microsoft released Team Foundation Server 2012 in mid August 2012. Well the company was using Borland Starteam as their source control and once starting to use TFS 2010, their developers and project managers were loving it since TFS is not just a source control tool and way much better then StarTeam. Anyways, long story short, they are now interested in thinking of upgrading to the newest version. Below are some basic Hardware and Software requirements for TFS 2012:Operating System:Windows Server 2008 with SP2 (only 64bit)Windows Server 2008 R2 with SP1 (only 64bit)Windows Server 2012 (only 64bit)SQL Server:SQL Server 2008 R2 and SQL Server 2012SQL Server 2008 is no longer supported.SQL Server Requirements for TFS.SharePoint Products:SharePoint Server 2010. (SharePoint Foundation 2010, Standard, Enterprise).MOSS 2007 (Standard, Enterprise)Windows SharePoint Services 3.0 (WSS 3.0)SharePoint Products Requirements for TFS.Project Server:Project Server 2010 with SP1.Project Server 2007 with SP2.Project Server Requirements for TFS.More information onf TFS Upgrade Requirements can be found here. Hardware Recommendations can be found here.Thanks,Vishal Mody
