• How do PGP and PEM differ?

  - by Dummy Derp

  Email messages are sent in plain text which means that the messages I send to Derpina are visible to anyone who somehow gets access to them while they are in transit. To overcome this, various encryption mechanisms were developed. PEM and PGP are two of them. PEM - canonically converts-adds digital signature-encrypts and sends PGP does exactly the same. So where do they differ? Or is it that PGP (being a program) is used to generate a PEM message?

• String or binary data would be truncated.

  - by Derek Dieter

  This error message is relatively straight forward. The way it normally happens is when you are trying to insert data from a table that contains values that have larger data lengths than the table you are trying to insert into. An example of this would be trying to insert data from a permanent table, into [...]

• Mount: "The disk drive for UUID=<uuid for /> is not ready yet or not present."

  - by searchfgold6789

  I recently did the update from 12.04 to 12.10 on my old Dell Latitude CPx laptop (Pentium III). When I rebooted I got this error message with no response from keyboard input. Below it is says Wait to continue, press S to skip mounting, or M for manual recovery. I also see occasional errors pop up on the screen from mountall and Plymouth. I can still get into Recovery Mode. Can anyone shed some light on the matter?

• Social media and special characters

  - by John Paul Cook

  I’ve previously blogged about using Unicode with T-SQL to put superscripts, subscripts, and special characters into text strings. Unicode is also useful in formatting social media such as Facebook, Twitter, and that dinosaur otherwise known as email. When you can’t set properties of text such as italicizing the subject line of an email message or adding subscripts to a Facebook post, Unicode can make it possible. There are Unicode characters that are intrinsically italicized. Others are intrinsically...(read more)

• Where is Sphinx located after I install it?

  - by Alex

  I have to install Sphinx on my Ubuntu 11.10 for it to work on a ruby app. I managed to install it through synaptics, however when I run my sphinx (rake ts:rebuild) I get an error message saying: Sphinx cannot be found on your system. You may need to configure the following settings in your config/sphinx.yml file: * bin_path * searchd_binary_name * indexer_binary_name I guess I just need to edit the sphinx.yml file with the right info but hey, I can't seem to find out where sphinx is. Any help?

• How to Remove Extensions From, and Force the Trailing Slash at the End of URLs?

  - by Kronbernkzion

  Example of current file structure: example.com/foo.php example.com/bar.html example.com/directory/ example.com/directory/foo.php example.com/directory/bar.html example.com/cgi-bin/directory/foo.cgi I would like to remove HTML, PHP and CGI extensions from, and then force the trailing slash at the end of URLs. So, it could look like this: example.com/foo/ example.com/bar/ example.com/directory/ example.com/directory/foo/ example.com/directory/bar/ example.com/cgi-bin/directory/foo/ I am very frustrated because I've searched for 17 hours straight for solution and visited more than a few hundred pages on various blogs and forums. I'm not joking. So I think I've done my research. Here is the code that sits in my .htaccess file right now: RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME}\.html -f RewriteRule ^(([^/]+/)*[^./]+)/$ $1.html RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_URI} !(\.[a-zA-Z0-9]|/)$ RewriteRule (.*)$ /$1/ [R=301,L] As you can see, this code only removes .html (and I'm not very happy with it because I think it could be done a lot simpler). I can remove the extension from PHP files when I rename them to .html through .htaccess, but that's not what I want. I want to remove it straight. This is the first thing I don't know how to do. The second thing is actually very annoying. My .htaccess file with code above, adds .html/ to every string entered after example.com/directory/foo/. So if I enter example.com/directory/foo/bar (obviously /bar doesn't exist since foo is a file), instead of just displaying message that page is not found, it converts it to example.com/directory/foo/bar.html/, then searches for a file for a few seconds and then displays the not found message. This, of course, is bad behavior. So, once again, I need the code in .htaccess to do the following things: Remove .html extension Remove .php extension Remove .cgi extension Force the trailing slash at the end of URLs Requests should behave correctly (no adding trailing slashes or extensions to strings if file or directory doesn't exist on server) Code should be as simple as possible I would very much appreciate any help. And to first person that gives me the solution, I'll send two $50 iTunes Store gift cards for US store. If this offends anyone, I am truly sorry and I apologize. Thanks in advance.

• Opening / using WUBI after downloading

  - by Jon

  I have no problem downloading WUBI either using Firefox or IE. Either way, however, when I try to run or open it, I get a message to the effect that the file cannot run because the configuration is incorrect and "re-installing the file may help" (which it doesn't - I've tried several times). What am doing wrong ? I am running XP Pro. (Note: my Ubuntu CD works just fine but I want to install Ubuntu inside Windows).

• BIDS Helper 1.6 Beta Release (now with SQL 2012 support!)

  - by Darren Gosbell

  The beta for BIDS Helper 1.6 was just released. We have not updated the version notification just yet as we would like to get some feedback on people's experiences with the SQL 2012 version. So if you are using SQL 2012, go grab it and let us know how you go (you can post a comment on this blog post or on the BIDS Helper site itself). This is the first release that supports SQL 2012 and consequently also the first release that runs in Visual Studio 2010. A big thanks to Greg Galloway for doing the bulk of the work on this release. Please note that if you are doing an xcopy deploy that you will need to unblock the files you download or you will get a cryptic error message. This appears to be caused by a security update to either Visual Studio or the .Net framework – the xcopy deploy instructions have been updated to show you how to do this. Below are the notes from the release page. ====== This beta release is the first to support SQL Server 2012 (in addition to SQL Server 2005, 2008, and 2008 R2). Since it is marked as a beta release, we are looking for bug reports in the next few months as you use BIDS Helper on real projects. In addition to getting all existing BIDS Helper functionality working appropriately in SQL Server 2012 (SSDT), the following features are new... Analysis Services Tabular Smart Diff Tabular Actions Editor Tabular HideMemberIf Tabular Pre-Build Fixes and Updates The Unused Datasets feature for Reporting Services now accounts for new features in Reporting Services 2008 R2 like Lookups and new features in Reporting Services 2012. SSIS: emit an informational message when a variable has an expression defined and EvaluateAsExpression = False SSAS: roles reports points to wrong server SSIS - Variable Copy / Move broken in v1.5 "Unused DataSets Report" not showing up in Context menu on VS2005 if Solution Folders used SSAS Tabular: Create a UI for managing actions SSAS Tabular: Smart Diff improvements for new schema and Tabular models SSIS: Copy/Move Variable Erroring due to custom Control Flow item Icon SSIS Performance Visualization Index out of range fixing bugs in AggManager when aggregation design IDs don't match names The exe downloads are a self extracting installer, the zip downloads allow for an xcopy deploy. Make sure to note the updated xcopy deploy instructions for SQL Server 2012.

• " this kernel required an X86-64 CPU, but only detected a i686 CPU"

  - by jy19

  I recently decided to use Virtualbox to run Ubuntu, but I get the message this kernel required an X86-64 CPU, but only detected a i686 CPU I've already enabled virtualization in BIOS, but that doesn't seem to work. Many other solutions suggest that I should download the 32-bit version, and not the 64-bit. I'm not sure about that though, since my computer clearly says "64-bit operating system" under systems. But I might just be mistaken.

• How to Add a Business Card Image to a Signature in Outlook 2013 Without the vCard (.vcf) File

  - by Lori Kaufman

  When you add a business card to a signature, an image of the business card is inserted into the signature and the vCard (.vcf) file is attached. If you don’t want to attach the vCard file, you can insert the image only into your signature. To insert only the image of your business card without the .vcf file, click People on the Navigation Bar at the bottom of the Outlook window. To get a business card image we can use, we must view the contacts in any form other than People, so we can open the full contact editing window. To do this, click on a different view in the Current View section of the Home tab. We chose to view our contacts in the Business Card format. Double-click on your contact in the current view. The full contact editing window displays with an image of the business card on the right. Right-click on the business card image and select Copy Image from the popup menu. To close the contact editing window, click the File tab and click Close in the menu list on the left. NOTE: You can also click the X in the upper, right corner of the contact editing window to close it. To open the signature editor, click the File tab. Click Options in the menu list on the left side of the Account Information screen. On the Outlook Options dialog box, click Mail in the list of options on the left side of the dialog box. On the Mail screen, click Signatures in the Compose messages section. NOTE: You can also access the Signatures and Stationery dialog box from the Message window for new emails and drafts. Click New Email on the Home tab or double-click an email in the Drafts folder to access the Message window. For more information, see our article about assigning a default signature. In the signature editor, right-click and select Paste from the popup menu. The image is inserted into the signature. You can also use this method to copy a business card image for use in other documents and programs. It’s also possible to insert the vCard (.vcf) file into a signature without the image. We’ll cover that topic tomorrow.

• update manager - insufficient storage space (false alarm)

• Nautilus copies files but not directories from samba server on OS X

  - by camsolo

  I need to copy files from OS X on a Mac to Ubuntu on a PC. I enabled File Sharing on the Mac and selected the samba option. I was then able to connect to the samba server in Nautilus. Copying files was no problem, but copying directories failed, with the error message "is a directory". I can accomplish what I want using samba in the terminal. But it would be more conveninient to do this in Nautilus.

• What is SOA ?

  - by llaszews

  First, let’s mention what SOA is not: • SOA is not the same thing as web services. Web Services implies the use of standard such as Java/JAX-RPC, .NET or REST. Web Services also implies the use of a WSDL, SOAP, and/or J2EE Connector Architecture (J2EE CA) and HTTP. SOA architectures can be implemented using J2EE CA, XML file transfer or Remote Procedural Call (RPC) over File Transfer Protocol (FTP), TCP/IP, Remote Method Invocation (RMI) or other protocols. In other words, Web Services are a very specific set of technologies. SOA is a concept and can be implemented in many different ways. Some very rudimentary, such as transfering flat files between applications. • SOA will not solve all of your problems. It will make your business more agile, increase business visibility, reduce integration costs and provide better reuse. However, if you don’t need help in these area or expect SOA to cure all of your IT problems, you are looking in the wrong place. • The concepts behind SOA are not new, but SOA is also not mature. SOA as it stands today has really only been around for 5 years. The concepts of standards based protocol handlers, predefined communication schemas and remote method invocation have been around for decades. So, what is SOA? SOA is an architectural blueprint, a way of developing applications, and a set of best practices. SOA is not an ‘out of the box’ solution you buy, install and then have up and running in a matter of months. SOA is a journey to a better way of doing business and the technology architecture to support this better way of doing business. SOA is also a broader set of technologies including more then just web services. Techologies like an Enterpirse Service Bus (ESB), Business Processs Execution Language (BPEL), message queues and Business Activity Monitoring (BAM) all are part of a SOA architecture.

• Chrome OS is missing or damaged

  My Google Chrome CR-48 started flaking out/rebooting and finally this message.  This post solved the problem quite easily. http://cr-48.wikispaces.com/Reseat+SSD+Cable Two hints: 1) you need to pull off the rubber feet to get at some screws. 2) the real problem is the little white clip under the cable.  Don’t worry about reseating anything, Just push the cable back on and the little white clip back up to snap in place and hold the cable.

• Help identify the pattern for reacting on updates

  - by Mike

  There's an entity that gets updated from external sources. Update events are at random intervals. And the entity has to be processed once updated. Multiple updates may be multiplexed. In other words there's a need for the most current state of entity to be processed. There's a point of no-return during processing where the current state (and the state is consistent i.e. no partial update is made) of entity is saved somewhere else and processing goes on independently of any arriving updates. Every consequent set of updates has to trigger processing i.e. system should not forget about updates. And for each entity there should be no more than one running processing (before the point of no-return) i.e. the entity state should not be processed more than once. So what I'm looking for is a pattern to cancel current processing before the point of no return or abandon processing results if an update arrives. The main challenge is to minimize race conditions and maintain integrity. The entity sits mainly in database with some files on disk. And the system is in .NET with web-services and message queues. What comes to my mind is a database queue-like table. An arriving update inserts row in that table and the processing is launched. The processing gathers necessary data before the point of no-return and once it reaches this barrier it looks into the queue table and checks whether there're more recent updates for the entity. If there are new updates the processing simply shuts down and its data is discarded. Otherwise the processing data is persisted and it goes beyond the point of no-return. Though it looks like a solution to me it is not quite elegant and I believe this scenario may be supported by some sort of middleware. If I would use message queues for this then there's a need to access the queue API in the point of no-return to check for the existence of new messages. And this approach also lacks elegance. Is there a name for this pattern and an existing solution?

• Can not authenticate to run GParted

  - by alfish

  Whenever I try to run a program from gnome gui, I get message Authenticated is required to run the Gparted Partition Editor The same goes for all programs that need root permission and I try to run from 'System tools' in my gnome-fallback. However the same user can become root in gnome terminal with no problem (I added the user to sudoers). I must mention that I've changed the user's password after OS install, so I think I need to update something but don't know what. I appreciate your hints.
