  • How to version lock packages in Ubuntu?

    - by Sandra
    On CentOS exists the yum versionlock option, where you can lock a package to a specific version, so it is never upgraded past that. I would like that puppet-server-2.7.19-1 puppet-2.7.19-1 stays on 2.7, and never upgraded to 3.0. Puppet Labs have released 3.0 and put it into the stable repo, so 2.7 will get upgraded to 3.0, which is not backwards compatible. Does Ubuntu have something similar to yum versionlock?

  • Which folder lock application will meet this requirement?

    - by user1540992
    I want any third party(either commercial or Open source) folder lock application that protects file with password without hiding the files. The locked folder should be displayed to user as password protected folder, when user try to open the folder, it should ask password. When the user enters correct password it should open, otherwise it should throw an error. Is there any application with this quality? I searched a lot, but I could not find any.

  • Free internet radio station server software with remote broadcasting?

    - by Zachary Brown
    I am in the process of creating an internet radio station, but the two djs I have for it are not able to be in one place. I need for them to be able to login to a web based broadcasting session that still has full functionality. They need to be able to broadcast thier live shows with talk and music. The music will be stroed on the server. I have checked out the Broadwave media streaming server from NCH, but ti does not have the ability to login as a dj from a remote computer. I don't have any money for this, so I need it to be free. If this is not possible, I need it to be cheap!

  • What is the best free Java based bug tracker?

    - by Vladimir Dyuzhev
    For internal development team I'm looking for a bug tracker. Important requirements are: Free (must have) WAR/EAR-deployable (must have; support team prefers to have all apps deployed same way) Nice UI (nice to have) UPDATE Since I wrote this, Atlassian has introduced a $10 (ten, not ten thousand!) version of JIRA for 10 developers. I think it's as good as it can get -- best issue tracker out there with all enterprise features, for the cost of a few coffees. I have bought it for my current group out of my own pocket (to avoid bureaucracy).

  • Add Free Windows Live Apps to Your Website or Blog

    - by Matthew Guay
    Would you like to use Hotmail, Office Web Apps, Messenger, and more on your website domain?  Here’s how you can add Windows Live to your website for free. Microsoft offers a popular suite of online communications products including Hotmail and Messenger.  Although Hotmail hasn’t been as popular in recent years as Gmail, it is getting a refresh this summer that might make it an even better email solution.  Additionally, the new Office Web Apps offer great compatibility with Office documents. While Skydrive offers 25Gb of free online file storage for all users, so Windows Live can make a great communications solution for your domain. Note: To signup for Windows Live for your domain, you will need to be able to add info to your WordPress.com blog or change Domain settings manually. Getting Started Open the Windows Live Custom Domains page (Link below) to get started adding Windows Live to your domain.  Your free Windows Live account will let you create up to 500 accounts, so it’s great for teams and groups that want to have customized email addresses in addition to those who just want an email account for their website. Enter your domain or subdomain you want to add to Windows Live in the box, and then select whether you want to setup Hotmail with this or now.  We want to add email to our domain, so select Set up Windows Live Hotmail for my domain and click Continue. You’ll need to sign in with a Windows Live ID to create the account, or choose to create a new Windows Live account associated with your domain.   Sign in with your Windows Live ID…this can be a Hotmail, Live Messenger, XBOX Live, Zune ID, or Microsoft.com account. Or, enter your information to create a new Windows Live ID if you selected the second option. Now, review your settings and make sure everything looks correct.  Click the I Accept button to setup your account.   Your account is now fully setup, but you’ll need to add or edit DNS information on your site.  The steps are slightly different depending if your site is hosted on WordPress.com, on your own server, or hosting service. We’ll show you how to do it on either one. First, though, note the information below this box.  You’ll see settings for your Mail setup…   Security settings…   And Messenger integration.  Make note of the settings, especially the circled ones, as we’ll need them in the next step. Integrate Windows Live with Your WordPress Blog If the domain you added to Windows Live is for your WordPress blog, login to your WordPress dashboard in a separate browser window or tab.  Click the arrow beside Upgrades, and select Domains from the menu. Click the Edit DNS link beside the domain name you’re adding to Windows Live. In the text box on this page, enter the following, replacing Your_info with your code from the Mail Setup box in your Windows Live Dashboard.  Note that this is the blurred section in our screenshots.  It should be a numerical code like 1234567890.pamx1.hotmail.com. MX 10 Your_info.pamx1.hotmail.com. TXT v=spf1 include:hotmail.com ~all CNAME Your_info domains.live.com. Click Save DNS records, and your settings are saved to WordPress.  Note that this will only integrate email with your WordPress account; you cannot integrate Messenger with a domain hosted on WordPress.com. Finally, return to your Windows Live Settings page and click Refresh.  If your settings are correct, you’ll now be ready to use Windows Live on your WordPress.com domain. Integrate Windows Live with Your Own Server If your website is hosted on your own server or hosting account, you’ll need to take a few more steps to add Windows Live to your domain.  This is fairly easy, but the steps may be different depending on your hosting company or registrar.  With some hosts, you may have to contact support to have them add the MX records for you.  Our site’s host uses the popular cPanel for website administration, so here’s how we added the MX Entries through cPanel. Login to your website’s cPanel, and select MX Entry under the Mail section. In the text box on this page, enter the following, replacing Your_info with your code from the Mail Setup box in your Windows Live Dashboard.  Note that this is the blurred section in our screenshots.  It should be a numerical code like 1234567890.pamx1.hotmail.com. MX 10 Your_info.pamx1.hotmail.com. Now, go back to your cPanel home, and select Advanced DNS Zone Editor under Domains. Here, add a TXT record with the following info: Name: yoursite.com. TTL: 3600 TXT Data: v=spf1 include:hotmail.com ~all Click Add Record and your Mail integration data is all configured. To integrate Messenger with your own domain, you’ll have to add an SRV entry to your DNS settings.  cPanel doesn’t have an option for this, so we had to contact our site’s hosting company and they added the entry for us.  Copy all of the information in the Messenger box and send it to your domain support, and they should be able to add this for you.  Alternately, if you don’t want or need Messenger, then you can simply skip this step. Once all of your settings are in place, return to your Windows Live Settings page and click Refresh.  If your settings are correct, you’ll now be ready to use Windows Live on your WordPress.com domain. Create a New Email Account On Your Domain Welcome to your new Windows Live admin page!  Now you can add email accounts so you and anyone else you want can access Hotmail and the other Windows Live apps with your domain.  Click Add to add an account. Enter an account name, which will be the email address of the account, e.g. [email protected].  Then enter the user’s name and a password for the account.  By default this will be a temporary password, and the user will have to change it on first log-in, but if you’re setting up this account for yourself, you can uncheck the box and keep this as your standard password. Now, go to www.mail.live.com, and sign in with your new email address and password.  Remember, your email address is your username previously entered followed by @yourdomain.com. To finish setting up the email account, enter your password, secret question and answer, alternate email, and location information.  Click I accept to finish setting up your new email account. Enter the characters in the Captcha to confirm you’re a human, and click Continue. Your new Hotmail inbox will now load, and you’ll have a welcome email in your inbox.  This works the same as normal Hotmail, except this time, your email address is with your own domain. You can now access any of the Windows Live services from the top-level menu. Here’s an Excel Spreadsheet open in the new Office Web Apps via SkyDrive on our new Windows Live account. If you setup Messenger access previously, you can now sign in to Windows Live Messenger using your new @yourdomain.com account as well. Important Links Accessing your Windows Live accounts is easy.  Simply go to any Windows Live site, such as www.hotmail.com or www.skydrive.com, and sign in with your new Windows Live ID from your domain as normal.  You don’t need a special address to access your account; it works just like the standard public Hotmail accounts. To administer your Windows Live for your domain, go to https://domains.live.com/ and sign in with the Windows Live ID you used to create the account.  Here you can add more users, change settings, and view usage details for the Windows Live accounts on your domain. Conclusion Windows Live is easy to add to your domain, and lets you create up to 500 email address for it.  With the upcoming updates to Hotmail and Office Web Apps coming this summer, this can be a nice way to make your domain even more useful.  And with 500 email accounts, you can easily let your team take advantage of your unique address as well. If you’d rather use Google’s online applications with your domain, check out our article on how to add free Google apps to your website or blog.

  • VSTO is Free But Aspose is Speed

    - by Ken Cox [MVP]
    I’ve taken over the completion, deployment, and maintenance of an ASP.NET Web site that generates Office documents using VSTO. VSTO’s a decent concept and works fine for small-scale scenarios like a desktop app or small intranet. However, with multiple simultaneous requests via ASP.NET, we found the Web server performance suffered badly. To spread out the server’s workload, I implemented MSMQ task queuing via a WCF Windows service.  That helped a lot. IIS didn’t drag with only one VSTO/Office instance running. But I  still found it taking too long to produce a single report. A nicely formatted VSTO Excel document was taking 45 minutes.  (The client  didn’t know any better and therefore considered 45 minutes tolerable.) On my own time, I pulled out an old copy of Aspose.Total for .NET. Within an hour, I had converted the VSTO Excel C# code to Aspose Cells code. The improvement was astonishing: Instead of the 45-minutes, the report took under a minute! I’ve pasted the client’s exact chat response after he tried the speedy Aspose version: “WWWWWOOOOOOOOWWWWWWWW!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!” Microsoft’s VSTO is a free product while the Aspose components cost $$$.  Certainly, it can be a tough call when budgets are tight. If you’re trying to convince the client to shell out for something more suitable for the application, get an eval version of Aspose.Total and offer a direct comparison demo. Ken Full Disclosure: Aspose (like several other component vendors) gives free copies of their suite to MVPs and other .NET influencers.

  • Booby Traps and Locked-in Kids: An Interview with a Safecracker

    - by Jason Fitzpatrick
    While most of our articles focus on security of the digital sort, this interview with a professional safecracker is an interesting look the physical side of securing your goods. As part of their Interviews with People Who Have Interesting or Unusual Jobs series over at McSweeney’s, they interviewed Ken Doyle, a professional a locksmithing and safecracking veteran with 30 years of industry experience. The interview is both entertaining and an interesting read. One of the more unusual aspects of safecracking he highlights: Q: Do you ever look inside? A: I NEVER look. It’s none of my business. Involving yourself in people’s private affairs can lead to being subpoenaed in a lawsuit or criminal trial. Besides, I’d prefer not knowing about a client’s drug stash, personal porn, or belly button lint collection. When I’m done I gather my tools and walk to the truck to write my invoice. Sometimes I’m out of the room before they open it. I don’t want to be nearby if there is a booby trap. Q: Why would there be a booby trap? A: The safe owner intentionally uses trip mechanisms, explosives or tear gas devices to “deter” unauthorized entry into his safe. It’s pretty stupid because I have yet to see any signs warning a would-be culprit about the danger.

  • Use a Free Utility to Create Multiple Virtual Desktops in Windows

    - by Lori Kaufman
    If you’ve used Linux, you’re probably familiar with the virtual desktop feature. It provides a convenient way to organize programs and folders open on your desktop. You can switch among multiple desktops and have different programs and folders open on each one. However, virtual desktops is a feature missing in Windows. There are many third-party options for adding virtual desktops to Windows, including one called Dexpot, which we have covered previously. Dexpot is free, but only for private use. Companies, public institutions, non-profit organizations, and even freelancers and self-employed people must buy the program. We found another virtual desktop tool that is completely free for everyone to use, called mDesktop. It’s a lightweight, open source program that allows you to switch among multiple desktops using hot keys and specify open programs or folders to be active on all desktops. You can use mDesktop to group related programs or to work on different projects on separate desktops. mDesktop is portable and does not need to be installed. Simply extract the .zip file you downloaded (see the link at the end of this article) and double-click the mDesktop.exe file.

  • Out of space despite lots of free space remaining

    - by Kristian Thomsen
    When upgrading Ubuntu from 11.10 to 12.04 I discovered an unexpected problem. The upgrade was stopped because there wasn't enough free space for the installation. I managed to free some space and do the upgrade but now a prompt appears after logging in saying I'm out of space. This prompt asks me if I want to examine the problem. The "Disk Usage Analyser" is opened. In the top it says: Total filesystem capacity: 47.0 GB (used: 13.5 GB available: 33.4 GB) Folder -- Usage -- Size / -- 100% -- 12.5 GB usr -- 44.8 % -- 5.6 GB home -- 30.3 % -- 3.8 GB lib -- 13.0 % -- 1.6 GB var -- 9.1 % -- 1.1 GB boot 2.5 % 309.5 GB and a lot of small contributors like: etc, opt, sbin, bin etc. I do not really understand this problem since the analyser in the top says that I have 33.4 GB left in this file system. What can I do to make Ubuntu use the remaining space? Running df -i in the terminal gives: Filesystem Inodes IUsed IFree IUse% Mounted on /dev/sda7 610800 576874 33926 95% / udev 213451 563 212888 1% /dev tmpfs 218524 486 218038 1% /run none 218524 3 218521 1% /run/lock none 218524 7 218517 1% /run/shm /dev/sda8 2264752 16371 2248381 1% /home What does this mean?

  • Free Updates and Errata for Oracle Linux

    - by Lenz Grimmer
    ISO images of the Oracle Linux installation media as well as individual binary RPMs (and the sources) of major and minor releases (Updates) have always been freely available for download, use and distribution, ever since we started the Oracle Linux support program. We're now taking this a step further: in addition to the above, we will now also provide updated packages or errata for free from separate yum repositories on http://public-yum.oracle.com. If you would like to keep your Oracle Linux system up to date, you can now do so by subscribing your system to the respective "_latest" repository for your distribution, e.g. "ol6_latest" for Oracle Linux 6. See the installation instructions on the public yum front page for details on how enable these repositories. If you would like to also receive free updates to the Unbreakable Enterprise Kernel Release 2, make sure to enable the "[ol6_UEK_latest]" repository as well - updates to the kernel will be made available from this separate channel until it is included in the next set of installation media. Now what does this mean for Oracle Network Support? Getting access to the updates and errata was just one part of the offering – the following benefits will still only be available with an Oracle Linux Support Subscription only: Full indemnification against intellectual property claims. Use of base functionality in Enterprise Manager 12c for Linux and Enterprise Manager OpsCenter for provisioning, patching, management and monitoring of Oracle Linux Access to additional software channels on the Unbreakable Linux Network (ULN) (e.g. DTrace beta releases or ASM support packages) Wim also published a blog post with his take on the announcement.

  • Best Free software for hosting user guides

    - by Hippyjim
    Hi All After having to clean up spam from a MediaWiki install for the umpteenth time, despite a recaptcha plugin "preventing" automated signups, I'm wondering if MediaWiki is the right choice as a CMS for hosting user manuals and guides. I've always loved the way wikis can let the guides be edited and commented on collaboratively, but I'm getting tired of dealing with automated vandals. I've disabled edits & signups for now, but as I'm having to go through the pain of cleaning thousands of junk pages, I'm beginning to think I should cut my losses and look for a better alternative. Does anyone know of suitable a FOSS application (preferably PHP / MySQL based) that would be simple for a non-coder (our manual writer) to edit, but that has all the interconnectivity, and searchability of a wiki? Or should I just bite the bullet again and lock the wiki down even further?

  • Free NOSQL database for use with C# client [closed]

    - by Mitten
    I've never used NOSQL databases before, but so far it seems like the best data storage solution for my project. I am going to implement a datamining application. The data I would like to mine is thousands of documents which cannot be imported into datamining applications. To make to import easier and faster (than importing thousands of documents) I am planning to import these documents into a NOSQL database first and when import NOSQL database into datamining software. At the very least once I have all the data in NOSQL database I should be able to code simplest datamining logic myself. Am I correct that NOSQL databases allow to creates records of data, but they don't mandate all the records to adhere to the same data schema (same column names/types in a classic table oriended SQL databases)? I think for each document I would create a row/entry/object (not sure what is the correct term is in use in NOSQL world) which would be a string id, few (columns) with unstructured text data, and a dozens of columns mostly of datetime and integer types. From its name NOSQL does not support SQL query syntax, but it support locating the object(row/entry?) by its unique id. Does NOSQL support qyuering objects using property=value syntax? Unfortunately most of free NOSQL db only support Java/C++ clients, which free NOSQL db would you recommend for a C# programmer?

  • Where did my free space go?

    - by Ari B. Friedman
    I have a storage drive (2TB) and an OS drive (90GB SSD). I've run out of space on the OS drive: /$ df -h Filesystem Size Used Avail Use% Mounted on /dev/sdb1 72G 72G 0 100% / udev 5.9G 12K 5.9G 1% /dev tmpfs 2.4G 1.2M 2.4G 1% /run none 5.0M 0 5.0M 0% /run/lock none 5.9G 428K 5.9G 1% /run/shm /dev/sda1 1.9T 639G 1.2T 37% /media/StorageDrive So be it. But when I attempt to figure out where the space has gone, I cannot find it anything remotely approaching the capacity of the drive: /$ sudo du -h -d 1 du: cannot access `./media/StorageDrive/home/ari/.gvfs': Permission denied 675G ./media 2.3G ./var 0 ./proc 7.0M ./tmp 27M ./boot 4.0K ./lib64 12K ./dev 44M ./home 16K ./lost+found 8.0M ./sbin 223M ./lib 4.0K ./selinux 1.4M ./run 140K ./root 8.8M ./bin 4.0K ./mnt 38M ./etc 8.0K ./srv 4.8G ./usr 65M ./opt 0 ./sys 682G . Note the difference between the total (682G) and the mounted drives in /media (675G) is only about 9G. How are 72G being used? Where is this dark matter hiding?
