• How To Create a Portable USB Version of Microsoft Office Starter 2010

  - by Taylor Gibb

  Microsoft Office 2010 Starter edition is a free, ad-supported version of Office 2010 meant to be included on new PCs. It only includes Word and Excel with a subset of features—but it does let you make a portable version. Here’s how to do it. Note: The download link provided in the following article is not exactly a “Microsoft Approved” link and may stop working at any time. Still, the Starter version of Office is meant to be ad-supported freeware, and they haven’t pulled the download despite widespread use of it online.

• can't use flash in ubuntu 13.10

  - by Orosjopie

  Since I upgraded to ubuntu 13.10, my flash isn't working anymore in firefox or opera. It only works in Google Chrome as it is included in the browser. I did check that I have flash plugin for firefox and so on installed. Everthing did work before the upgrade. When I try to install from adobe's website, it doens't pick up anymore the apt installer/ software center. You have to physically to go and look for the correct program to install flash, but I don't know where to look for it or choose it. Is there a other way like in terminal or somewhere else to reinstall it? Or what can I do?

• Unidata and RDB migrations to Oracle

  - by llaszews

  Have a couple of unique migrations that don't come along to often. They are Unidata and RDB migrations. The top three things that make these migration more challenging are: 1. No automated data migration tools - Because these migration don't happen that often, there are no tools in the market place to automated the data migration. 2. Application is tied to database - The application needs to be re-architected/re-engineered. Unidata Basic and COBOL for RDB. TSRI can migrate Basic to Java and PL/SQL. Transoft can migrate DEC COBOL to Java. 3. New client hardware potentially involved - Many Unidata and RDB based systems use 'green screens' as the front end. These are character based screens that will run on very old dumb terminals such as: Wyse and DEC 5250 terminals. The user interface can be replicated in a web browser but many times these old terminals do not support web browsers.

• Downloading large files hangs system

  - by Igor

  When Im trying to download large files, i.e. 1gb or more under FireFox, first of all it starts with very big download speed and in few seconds in almost get up to max (~11 MBps). It is downloading very fast, but when downloaded size becomes near 700-800mb and more, my system almost completely hangs, so I can do nothing - I just have to wait until it finishes downloading. Also when it hangs, I can't see the download progress - it looks like it completely hangs. Sometimes, however, if the file size is near 1gb, the system comes back from hang, finishing download, but sometimes I just cant wait before system comes back and have to kill FF from top (it takes me 2 minutes to do this, because of very slow system performance). I use Firefox as primary browser. If I use wget with direct link to file - everything is fine. Speed at max, no performance decrease. So what can I do?

• Handling packet impersonating in client-server model online game

  - by TheDespite

  I am designing a server-client model game library/engine. How do I, and should I even bother to handle frequent update packet possible impersonating? In my current design anyone could copy a packet from someone else and modify it to execute any non-critical action for another client. I am currently compressing all datagrams so that adds just a tad of security. Edit: One way I thought about was to send a unique "key" to the verified client every x_time and then the client has to add that to all of it's update packets until a new key is sent. Edit2: I should have mentioned that I am not concerned about whether the actions described in the packet are available to the client at the time, this is all checked by the server which I thought was obvious. I am only concerned about someone sending packets for another client.

• Setting up Oracle Linux 6 with public-yum for all updates

  - by wcoekaer

  I just wanted to give you a quick example on how to get started with Oracle Linux 6 and start using the updates we published on http://public-yum.oracle.com. Download Oracle Linux (without the requirement of a support subscription) from http://edelivery.oracle.com/linux. Install Oracle Linux from the ISO or DVD image Log in as user root Download the yum repo file from http://public-yum.oracle.com # cd /etc/yum.repos.d # wget http://public-yum.oracle.com/public-yum-ol6.repo If you want, you can edit the repo file and enable other repositories, I enabled [ol6_UEK_latest] by just setting enabled=1 in the file with a text editor. Run yum repolist to show the registered channels and you see we are including everything including the latest published RPMs. Now you can just run yum update and any time we release new security errata or bugfix errata for OL6, they will be posted and you will automatically get them. It's very easy, very convenient and actually very cool. We do a lot more than just build OL RPMs and distribute them, we have a very comprehensive test farm where we test the packages extensively.

• JS and CSS caching issue: possibly .htaccess related

  - by adamturtle

  I've been using the HTML5 Boilerplate for some web projects for a while now and have noticed the following issue cropping up on some sites. My CSS and JS files, when loaded by the browser, are being renamed to things like: ce.52b8fd529e8142bdb6c4f9e7f55aaec0.modernizr-1,o7,omin,l.js …in the case of modernizr-1.7.min.js The pattern always seems to add ce. or cc. in front of the filename. I'm not sure what's causing this, and it's frustrating since when I make updates to those files, the same old cached file is being loaded. I have to explicitly call modernizr-1.7.min.js?v=2 or something similar to get it to re-cache. I'd like to scrap it altogether but it still happens even when .htaccess is empty. Any ideas? Is anyone else experiencing this issue?

• Games with multiple flash files not working

  - by zlyfire

  I have download a flash game, since that's show the person coded it, and it is in multiple flash files to reduce overall file size or something. When I try to play it, I can only use the content within that one flash file, leading me to believe that it does not call upon other files within my computer. I kept the same file structure and everything as the download was, and another version of the same game I had on my windows laptop before my laptop died. It worked fine there, calling the files like it was supposed to. Is it just an Ubuntu/Linux/Unix-based bug, or is something going wrong? I've tried it in browser (firefox) and offline (gnash) and neither worked properly. Can anyone help me with this? Perhaps helping me find a way to get my game to work properly?

• Wireless not working, no driver showing in the Additional Drivers window

  - by edit lopez

  I am a new user of Ubuntu. I have a Asus Q501L laptop that came preinstalled with Windows 8, but I wanted to move from Windows and try something new, so I just decided to install Ubuntu without thinking to much about it. The problem I have is that I can't install the additional drivers. When I go to to Additional Drivers nothing appears, it just says: no proprietary drivers are in use and in small letters continues: a proprietary driver has private code that Ubuntu developers can't review and improve. security and others updates are dependent on drivers vendor.. I can't even use the wireless connection. I really don't know what to do. I tried to download the drivers from Asus, but when I tried to install them it said: an error occurred while loading the archive. Also I don't know the model of the PC wireless card. If there is something I can do to find out that please tell me. Thanks!

• 11.10 AMD64 alternate installer has broken packages?

  - by Ibrahim

  I'm installing Ubuntu 11.10 from the alternate install ISO because I need to use LVM. Unfortunately, at some point the installer fails because it can't install libpurple0 and ubuntu-desktop because they depend on libsasl2-modules but it's not installable somehow. It also has the same error for xserver-xorg-video-all but I think I could probably live without that one. Kind of annoying that this is broken, I'm guessing maybe if I had internet it would work but right now I'm on a campus network with a captive portal so I can't actually get a network connection without using a browser to log in. Just thought someone should know or maybe I'm doing something wrong. I'm going to try installing 11.04 alternate and then upgrading I guess.

• Receiving requests where absolute URL on page are morphed to relative URLs

  - by Jacob

  In our web pages, we have a hyperlink with an href to an absolute URL: https://some.other.host.com/blah.aspx?var1=val1&var2=val2 For some reason, in our logs, we see a lot of requests to URLs of this format: http://our.site.com/https:/some.other.host.com/blah.aspx?var1=val1&var2=val2 We don't have any JavaScript that would request that URL; it only appears inside of a hyperlink. Is there some sort of known bot, browser plugin, bug, etc. that could be responsible for these requests being made?

• Flash completely freeze computer

  - by Yanick Rochon

  Since this morning, and ever so frequently, Flash will completely freeze the computer as soon as something launches it. First, the web page will stop responding, then the entire browser, and after about 2 seconds, the mouse and keyboard will stop responding and the computer will escalate to 100% usage, and all that's left is to perform a hard reboot. I tried re-installing Flash, downgrade my kernel, nothing will do. I'm running Mint 13 64-bit (based on Ubuntu 12.04) with XFCE (not Xubuntu, I installed XFCE as separate package). It never freezes otherwise, so I know it's caused by Flash. How do I solve this issue? What could cause this?

• What should be included in risk management section of software's architecture documentation?

  - by Limbo Exile

  I am going to develop a Java application (a Spring Web application that will be used to extract data from various data sources) and I want to include risk management of the software in the architecture documentation. By risk management (I am not sure if this is the right name) I mean documenting possibilities of what can go wrong with the software and what to do in those cases. At first I tried to draft some lists, including things like database performance decrease, change of external components that the software interacts with, security breaches etc. But as I am not an experienced developer I cannot rely on those drafts, I don't think they are exhaustive. I searched web hoping to find something similar to the Joel Test or to find any other resource that will cite the most popular causes of problems that should be included and analyzed in risk management documentation, but I haven't found much. Finally, my question is: What should be included in risk management section of software's architecture documentation?

• Controllers in CodeIgniter

  - by Dileep Dil

  I little bit new to the CodeIgniter framework and this is my first project with this framework. During a chat on StackOverflow somebody said that we need to make controllers tiny as possible. Currently I have a default controller named home with 1332 lines of codes (and increasing) and a model named Profunction with 1356 lines of codes (and increasing). The controller class have about 46 functions on it and also with model class. I thought that Codeigniter can handle large Controllers or Models well, is there any problem/performance issue/security issues regarding this?

• Keyboard shortcuts get randomly reset

  - by Andrei

  I'm facing a rather weird issue in the past few days after doing a clean install of Ubuntu Oneiric (w/ gnome-shell) on my recently-bought Asus U36SD. I set up my keyboard shortcuts using System Settings Keyboard Shortcuts, and some of them get randomly reset. Most of my shortcuts include the win key (otherwise listed in the keyboard shortcuts as Mod4), but those containing only Mod4 + get reset every two-three reboots. For instance, Mod4 + T (for terminal), gets reset to the standard Ctrl + Alt + T, while Shift + Mod4 + W (for browser) doesn't (I've set up the latter with the Shift key, because it seems that Mod4 + W didn't get intercepted at all. Something similar goes for Mod4 + E for gedit, which only worked once or twice). I have no idea if this is a Ubuntu specific issue, or it's related to gnome-shell or even with my current hardware. Has this happened to any of you? If so, did you manage to fix it?

• IPSec Offload support in 82576GB controller for Linux

  - by Rodrigo Leal

  Due to migration of servers to cloud computing, we bought several NICs that support mechanisms like SRIOV and VMDQ. Furthermore, as security risk was also a concern and we did not want to create more overhead on the processor, IPSec Offload support was essential. The model chosen was: Intel Gigabit ET2 Quad Port Svr Adptr. (With 82576GB controller): http://ark.intel.com/products/49187/intel-gigabit-et2-quad-port-server-adapter However, we were unable to configure IPSec Offload on Linux. We tried to test on another server we have, a Windows Server 2012 R2, but again without success. It seems that the driver for this controller is not available for windows server 2012 R2, and Linux. The test on windows would be only for verification purposes, we will not use this platform. Could someone confirm this lack of support for Linux?

• "AND Operator" in PAM

  - by d_inevitable

  I need to prevent users from authenticating through Kerberos when the encrypted /home/users has not yet been mounted. (This is to avoid corrupting the ecryptfs mountpoint) Currently I have these lines in /etc/pam.d/common-auth: auth required pam_group.so use_first_pass auth [success=2 default=ignore] pam_krb5.so minimum_uid=1000 try_first_pass auth [success=1 default=ignore] pam_unix.so nullok_secure try_first_pass I am planning to use pam_exec.so to execute a script that will exit 1 if the ecyptfs mounts are not ready yet. Doing this: auth required pam_exec.so /etc/security/check_ecryptfs will lock me out for good if ecryptfs for some reason fails. In such case I would like to at least be able to login with a local (non-kerberos) user to fix the issue. Is there some sort of AND-Operator in which I can say that login through kerberos+ldap is only sufficient if both kerberos authentication and the ecryptfs mount has succeeded?

• How to do a cacheable redirection?

  - by John Doe

  When users enter my website example.com, their "preferred" language is detected and they are redirected (using a 301 Moved Permanently redirection) to example.com/en/ (for english), example.com/it/ (for italian), etc. It works perfectly, but when I analized my website with the Google Page Speed tool it gave me the following advice. Many pages, especially mobile pages, redirect users to a different URL, for instance from www.example.com to m.example.com. Making this redirect cacheable by the user's browser can speed up page load times for repeat visitors to a site. And later it says We recommend using a 302 redirect with a cache lifetime of one day. The redirect should include a Vary: User-Agent header as well as a Cache-Control: private header. So my questions are, how can I do a "cacheable" redirection in PHP? Would the following be enough? header("HTTP/1.0 302 Moved Temporarily"); header("Location: example.com/whatever"); exit;

I found the following similar question : Errors while updating Ubuntu 11.10 , But the solutions mentioned ( changing the download server, running apt-get clean, apt-get autoclean) and have also tried removing the /var/cache/apt/archives/lists direcotry. As a result of this, I am unable to install any new packages.

• Should I use the same Google Analytics code for my website and native mobile app?

  - by Drew

  My website is a forum. The native mobile app's only function is to access the forum and provide a better experience than can be provided through the browser. Given that the same content is being accessed, should I use the same Google Analytics tracking code? Or should I create a new property and select "Not a website" when it asks for the website? I was not able to find anything that discussed this and what would be best practice, given that the same content is being accessed. Thanks!
