• Add a Scrollable Multi-Row Bookmarks Toolbar to Firefox

  - by Asian Angel

  If you keep a lot of bookmarks available in your Bookmarks Toolbar then you know that accessing some of them is not as easy as you would like. Now you can simplify the access process with the Multirow Bookmarks Toolbar for Firefox. Before As you can see it has not taken long to fill up our “Bookmarks Toolbar” and use of the drop-down list is required. If you do not keep too many bookmarks in the “Bookmarks Toolbar” then that may not be a bad thing but what if you have a very large number of bookmarks there? Multirow Bookmarks Toolbar in Action As soon as you have installed the extension and restarted Firefox you will see the default three rows display. If you are not worried about UI space then you are good to go. Those of you who like keeping the UI space to a minimum will want to have a look at this next part… You are not locked into a “three rows setup” with this extension. If you are ok with two rows then you can select for that in the “Options” and and enjoy a mini scrollbar on the right side. For our example we still had easy access to all three rows. Two rows still too much? Not a problem. Set the number of rows for one only in the “Options” and still enjoy that scrolling goodness. If you do select for one row only do not panic when you do not see a scrollbar…it is still there. Hold your mouse over where the scrollbar is shown in the image above and use your middle mouse button to scroll through the multiple rows. You can see the transition between the second and third rows on our browser here… Nice, huh? Options The “Options” are extremely easy to work with…just enable/disable the extension here and set the number of rows that you want visible. Conclusion While the Multirow Bookmarks Toolbar extension may not seem like much at first glance it does provide some nice flexibility for your “Bookmarks Toolbar”. You can save space and access your bookmarks easily without those drop-down lists. If you are looking for another great way to make the best use of the space available in your “Bookmarks Toolbar” then be sure to read our article on the Smart Bookmarks Bar extension for Firefox here.

• Friday Fun: Play Tetris in Google Chrome

  - by Asian Angel

  Do you prefer playing classic games rather than the newer ones? Then get ready for some classic goodness with the JC-Tetris extension for Google Chrome. JC-Tetris in Action When you click on your new “JC-Tetris Toolbar Button” a new mini-Chrome window will open with the game displayed inside. This could be very convenient for those who would like or need to pause the game, minimize the window, and finish the game later. All that is needed to play are the four “Arrow Keys & the Space Bar”. Note: The text was small when the window first opened during our test so we used the “Ctrl +” keyboard shortcut twice to enlarge it. You may or may not experience similar text size results. Like any Tetris game things start out “quietly enough” but this one speeds up quickly, so be prepared! Notice that you do get a warning of what is waiting to drop onto the game board on the left side. Whenever you complete a game you will see this small window asking if you would like to enter a name for the score…you can easily ignore/bypass the window by clicking “Cancel”. Another game and a much better result. Do not be surprised if you feel that little burst of “rushed panic” at the end! Conclusion JC-Tetris is an enjoyable way to relax when you need a break. The ability to pause the game and minimize it for later makes it even better. Have fun!

• [SQLServer JDBC Driver][SQLServer]Could not find stored procedure 'master..xp_jdbc_open2'.

  - by Vijaya Moderator -Oracle

  When connecting to MS SQL Server Database via Weblogic Datasource and using XA jdbc driver, the following error is thrown. <Jun 3, 2014 5:16:49 AM PDT> <Error> <Console> <BEA-240003> <Console encountered the following error java.sql.SQLException: [FMWGEN][SQLServer JDBC Driver][SQLServer]Could not find stored procedure 'master..xp_jdbc_open2'. at weblogic.jdbc.sqlserverbase.ddb_.b(Unknown Source)at weblogic.jdbc.sqlserverbase.ddb_.a(Unknown Source)at weblogic.jdbc.sqlserverbase.ddb9.b(Unknown Source)at weblogic.jdbc.sqlserverbase.ddb9.a(Unknown Source)at weblogic.jdbc.sqlserver.tds.ddr.v(Unknown Source)at weblogic.jdbc.sqlserver.tds.ddr.a(Unknown Source)at weblogic.jdbc.sqlserver.tds.ddq.a(Unknown Source)at weblogic.jdbc.sqlserver.tds.ddr.a(Unknown Source)at weblogic.jdbc.sqlserver.ddj.m(Unknown Source)at weblogic.jdbc.sqlserverbase.ddel.e(Unknown Source)at weblogic.jdbc.sqlserverbase.ddel.a(Unknown Source)  The cause behind the issue is that  the MS SQL Server was not installed with the Stored procedures to enable JTA/XA Solution To connect to SQL Server via XA Driver from WLS Datasource you need to install Stored Procedures for JTATo use JDBC distributed transactions through JTA, your system administrator should use the following procedure to install Microsoft SQL Server JDBC XA procedures. This procedure must be repeated for each MS SQL Server installation that will be involved in a distributed transaction.To install stored procedures for JTA:1. Copy the appropriate sqljdbc.dll and instjdbc.sql files from the WL_HOME\server\lib directory to the SQL_Server_Root/bin directory of the MS SQL Server database server, where WL_HOME is the directory in which WebLogic server is installed, typically c:\Oracle\Middleware\wlserver_10.x.  Note:  If you are installing stored procedures on a database server with multiple Microsoft SQL Server instances, each running SQL Server instance must be able to locate the sqljdbc.dll file.Therefore the sqljdbc.dll file needs to be anywhere on the global PATH or on the application-specific path. For the application-specific path, place the sqljdbc.dll file into the :\Program Files\Microsoft SQL Server\MSSQL$\Binn directory for each instance. 2. From the database server, use the ISQL utility to run the instjdbc.sql script. As a precaution, have your system administrator back up the master database before running instjdbc.sql. At a command prompt, use the following syntax to run instjdbc.sql:  ISQL -Usa -Psa_password -Sserver_name -ilocation\instjdbc.sql  where:  sa_password is the password of the system administrator.  server_name is the name of the server on which SQL Server resides.  location is the full path to instjdbc.sql. (You copied this script to the SQL_Server_Root/bin directory in step 1.)  The instjdbc.sql script generates many messages. In general, these messages can be ignored; however, the system administrator should scan the output for any messages that may indicate an execution error. The last message should indicate that instjdbc.sql ran successfully. The script fails when there is insufficient space available in the master database to store the JDBC XA procedures or to log changes to existing procedures.

• Selling Solutions, Not Products

  - by David Dorf

  When I think about next-generation retailers, the names that come to mind are Apple, Whole Foods, Lulu Lemon, and IKEA.  They may not be the biggest retailers, but they are certainly growing fast. Success is never defined by just one dimension, and these retailers execute well across many dimensions, but the one that stands out for me is customer experience.  These stores feel...approachable...part of the community...local.  Customers are not intimidated to ask questions, and staff seem to go out of their way to help. What's makes these retailers stand out in the industry?  These retailers aren't selling products -- they're selling solutions.  Think about that.  You think you're going to the Apple store to buy a phone, but you're actually buying a communications solution that handles much, much more.  If you carry an iPhone, your life has changed.  The way you do things is different.  The impacts go much beyond a simple phone. Solutions start with a problem, which is why these retailers greet customers with "what brought you in today," or "can I answer any questions for you?"  Good retailers establish a relationship, even if it lasts only a few minutes. You don't walk into Whole Foods looking for cans of soup.  You are looking for meals: healthy snacks, interesting lunches, exotic dinners.  Its a learning experience where you might discover solutions to problems you didn't know you had.  Mention what foods you like, and you'll get a list of similar items you had not considered.  I didn't know I needed a closet organizer until I visited an IKEA and learned about all the options.  They were able to customize the solution to meet my needs, and now I'm much more organized. One of the differences between selling products and selling solutions is training.  Visit any of these retailers' sites and you'll see a long list of in-store events for the benefit of customers.  You can buy exercise clothing from Lulu Lemon, and also learn new yoga techniques, meet like-minded people, and branch off to other fitness regimes via their ambassadors.  You can visit the Geek Bar at Apple, eat lunch at IKEA, and learn to cook at Whole Foods. These retailers are making an investment in a relationship with their customers.  They are showing loyalty to their customers before asking for it back.  In the long-run, this strategic approach will outlive any scan-and-bag mentality.

• Claims-based Identity Terminology

  - by kaleidoscope

  There are several terms commonly used to describe claims-based identity, and it is important to clearly define these terms. · Identity In terms of Access Control, the term identity will be used to refer to a set of claims made by a trusted issuer about the user. · Claim You can think of a claim as a bit of identity information, such as name, email address, age, and so on. The more claims your service receives, the more you’ll know about the user who is making the request. · Security Token The user delivers a set of claims to your service piggybacked along with his or her request. In a REST Web service, these claims are carried in the Authorization header of the HTTP(S) request. Regardless of how they arrive, claims must somehow be serialized, and this is managed by security tokens. A security token is a serialized set of claims that is signed by the issuing authority. · Issuing Authority & Identity Provider An issuing authority has two main features. The first and most obvious is that it issues security tokens. The second feature is the logic that determines which claims to issue. This is based on the user’s identity, the resource to which the request applies, and possibly other contextual data such as time of day. This type of logic is often referred to as policy[1]. There are many issuing authorities, including Windows Live ID, ADFS, PingFederate from Ping Identity (a product that exposes user identities from the Java world), Facebook Connect, and more. Their job is to validate some credential from the user and issue a token with an identifier for the user's account and  possibly other identity attributes. These types of authorities are called identity providers (sometimes shortened as IdP). It’s ultimately their responsibility to answer the question, “who are you?” and ensure that the user knows his or her password, is in possession of a smart card, knows the PIN code, has a matching retinal scan, and so on. · Security Token Service (STS) A security token service (STS) is a technical term for the Web interface in an issuing authority that allows clients to request and receive a security token according to interoperable protocols that are discussed in the following section. This term comes from the WS-Trust standard, and is often used in the literature to refer to an issuing authority. STS when used from developer point of view indicates the URL to use to request a token from an issuer. For more details please refer to the link http://www.microsoft.com/windowsazure/developers/dotnetservices/ Geeta, G

• Add a Sleep Timer to Windows 7 Media Center

  - by DigitalGeekery

  Do you make it a habit of falling asleep at night while watching Windows Media Center? Today we are going to take a look at the MC7 Sleep Timer for Windows 7 Media Center. This simple little plugin allows you to schedule an automatic shutdown time in Media Center. Note: At this point MC7 Sleep Timer doesn’t work with extenders. If you’re using ClamAV or Panda it may detect this plugin as a virus, we’ve tested it and this is a false positive for these two antivirus apps. Installation and Usage Download and install MC7 Sleep Timer. (See download below) After the installation is finished, you will find MC7 Sleep Timer located in the Media Center Extras Library. Click on the tile to open the timer and configure your settings. The MC7 Sleep Timer will open in full screen mode. You can choose to shutdown the PC after 30 or 60 minutes, create a custom length shutdown timer at any 5 minute interval, or select the exact time you want the PC to shutdown.  After setting your PC to shutdown, you’ll get an audio confirmation. To set a custom timer length, scroll to the “Custom timer” option and click right or left on your Media Center remote or, the right or left arrow keys, to choose how many minutes before shutdown. To schedule a shutdown for a certain time, browse to the “Shutdown at time” button, and scroll right or left with the arrow keys on the keyboard or remote. When you’ve chosen your time, hit “Enter” on the keyboard or “OK” on the remote.   Clicking the “Monitor Off” button will turn off only the monitor and “Cancel Timer” will cancel your shutdown request. Conclusion If you often find yourself falling asleep every night watching Media Center and then fumbling and stumbling in the middle of the night to shutdown your computer, MC7 Sleep timer might just be a perfect addition to your Media Center setup.

Some reasons why you might want or need to clear your browser’s cache: Clear out older (or out of date) versions of images, etc. from your favorite websites Free up disk space Clearing the cache may help fix browser behavior issues Help protect privacy (i.e. images, etc. displayed within a personal account) Before For our example we loaded three webpages in order to add content to our browser’s cache. Using the “CacheViewer” we were able to easily see the contents of our browser’s cache after the webpages finished loading. What if you need to clear your cache immediately without restarting your browser (if the options are set to empty the cache on browser exit)? Note: CacheViewer is available via a separate extension and can be found here. Empty Cache Button in Action Once you install the extension all that you need to do is right click on any of your browser’s toolbars and select “Customise”. Drag the “Toolbar Button” to an appropriate location in your browser’s UI and you are ready to go. To clear your browser’s cache simply click the button…that is all there is to it. When the cache is empty you will see this small message window appear in the lower right corner of your “Desktop”. Opening up the “CacheViewer” again shows that everything has been cleared out. Terrific! Conclusion If you ever find yourself needing to clear your browser’s cache immediately then the Empty Cache Button extension provides an easy way to do so without restarting your browser (if the options are set to empty the cache on browser exit).

• How do I get the Apple Wireless Keyboard Working in 10.10?

  - by Jamie

  So I've gone and bought a Magic Mouse and Apple Wireless Non-Numeric Keyboard. The magic mouse worked out-of-the-box almost perfectly, except for the forward/back gesture which still isn't functioning, whereas the keyboard didn't. It has constant trouble with the bluetooth connection. Only the 7, 8 and 9 buttons and volume media keys correspond correctly with the output. Pressing every single key on keyboard has this output: 789/=456*123-0.+ When I use Blueman the keyboard can be setup and shows up in "Devices" but I get a warning when I click "Setup"; "Device added successfully, but failed to connect" (although removing the keyboard and setting it up as a new device doesn't incur this error). Using gnome-bluetooth I have encountered no error messages but it connects properly less often than Blueman and I can still only type the aforementioned output. What am I not doing? Where is this going wrong? EDIT: I have read this http://ubuntuforums.org/showthread.php?t=224673 inside out several times to no avail. It seems these commands don't work for me with the apple peripherals sudo hidd --search hcitool scan Fortunately I have the luxury of a 1TB hard drive, near limitless patience and no job. I have installed a fresh Ubuntu 10.10 64bit (albeit smaller than mine) and after updating and restarting for the first time, I set up my devices in exactly the same way as I have learnt on my original install I succeeded once again with the mouse and, to my joy, with the keyboard also. Though I could not seem to find Alt+F2 and had to reconfigure that and several other keyboard shortcuts, the keyboard is working and in a spectacular fashion. Still, this leaves me with the issue of my original install. I returned to it with some new found knowledge but failed again. Perhaps I have a missing dependancy? I did uninstall bluetooth after the initial set up and reinstalled it recently for the pupose of these peripherals. Maybe it's because I'm running 64bit? This is still not solved, but easily avoided by not changing too much from the original install. Just hide stuff or turn it off, don't uninstall too much.

• Regular Expressions Reference Tables Updated

  - by Jan Goyvaerts

  The regular expressions reference on the Regular-Expressions.info website was completely overhauled with the big update of that site last month. In the past, the reference section consisted of two parts. One part was a summary of the regex features commonly found in Perl-style regex flavors with short descriptions and examples. This part of the reference ignored differences between regex flavors and omitted most features that don’t have wide support. The other part was a regular expression flavor comparison that listed many more regex features along with YES/no indicators for many regex flavors, but without any explanations of the features. When reworking the site, I wanted to make the reference section more detailed, with descriptions and examples of all the syntax supported by the flavors discussed on the site. Doing that resulted in a reference that lists many features that are only supported by a few regex flavors. For such a reference to be usable, it needs to indicate which flavors support each feature. My original design for the new reference table used two rows for each feature. The first row had 4 columns with a label, syntax, description, and example, similar to the old reference tables. The second row had 20 columns indicating which versions of which flavors support these features. While the double-row design allowed all the information to fit within the table without requiring horizontal scrolling, it made it more difficult to quickly scan the tables for the feature you’re looking for. To make the new reference tables easier to read, they now have only a single row for each feature. The first 4 columns are the same as before. The remaining two columns show which versions of two regular expression flavors support the feature. You can use the drop-down lists above the table to choose the flavors the table should indicate. The site uses cookies to allow the flavor choices to persist while you navigate the reference. The result of this latest update is that the new regex tables are now just as easy to read as the ten-year-old tables on the old site were, while still covering all the features big and small of all the flavors discussed on the site.

• Android app to remote control Samsung Smart TVs

  - by Gopinath

  Smart TV Remote is an unofficial Android app that lets you control Samsung Smart TVs connected over a local WiFi network. This app comes very handy when you want to control your TV which is not in line of sight of your TV remote control or just want to use your mobile phone/tablet to control the TV. Setting up a TV  is very easy using auto scan feature . Once the TV is setup, you are all set to start using the app as a remote control. A traditional remote controls makes use of infra red technology and it needs to be in the line of sight of the TV receiver to work. But this app make use of WiFi technology which give it flexibility of controlling the TV as long as the mobile & TV is connected to WiFi network. It just works even if the TV is behind a wall. The App provides very easy to use options to switch between channels and separate remotes with media controls, smart hub features and a numeric key pad if you want to navigate to a channel through its number. The App also provides a home screen widget with volume controls and channel navigation options. I use  this App to control Samsung E Series Smart Tv at home and it works very well. I’m impressed by the ease at which it allows to setup a TV, support for multiple TVs, controlling the TV though I’m not in the line of sight and using volume buttons of smart phone to control volume of TV. What’s annoying and missing with the app As advertised the app works very well in controlling Samsung TVs (B-, C-, D- E-, and F-Series) except it is very painful to move mouse pointer while browsing web on TV. When you try to move mouse pointer using the App, it mouse painfully slow especially. I gave us using the app to control mouse pointer after trying couple of times. I installed this App thinking that it may help me browse web on Smart TVs, especially a key board support to type web urls. App does not supports entering text either while browsing web or searching through Smart TV apps like YouTube, App Store etc. Developers of this App never advertised keyboard support so no complaints about this. But it would be very helpful if the developers allow this app use as a keyboard and rescue me from the pain of typing text using TV Remote control. Overall this is a very nice app and worth trying out – Download Smart TV Remote from Google Play

• Make Chrome’s New Tab Page More Useful and Artistic

  - by Asian Angel

  Are you tired of the default New Tab Page in Google Chrome and want something more useful and artistic? Then join us as we look at the Incredible StartPage extension. Before Here is the default “New Tab Page” in our Chrome Browser…it looks rather plain and boring. How about something better? Incredible StartPage in Action This is what our “New Tab Page” looked like after installing the extension. As you can see there is a “Note Section”, “Closed Tabs Section”, “All Bookmarks Section”, and a “Bookmarks Toolbar (links only) Section”. Note: Clicking on links in Incredible StartPage will open them in the current tab. If you want you can easily modify how Incredible StartPage looks using the “Options” in the upper right corner. After only a couple of minutes our “New Tab Page” was looking nice…new background color, image, and altered note. A very useful feature of the “Note Section” is that you can add your notes to an e-mail by clicking on the “Post to Gmail Link” just below the note. Note: Special “Chrome Pages” (i.e. Extensions) will not open from the “Closed Tabs Section”. When you click on “Post to Gmail” a new tab will be opened with your notes pre-pasted into the main letter body. All that is left for you to do is select the appropriate e-mail address(es) and to make any desired modifications to the “Subject & Letter”. Going back to the “New Tab Page” you can trade bookmarks back and forth between the “All Bookmarks Section” and the “Bookmarks Toolbar Section”. Simply drag-and-drop as desired…but keep in mind that any changes made here will also be reflected in your “Bookmarks Toolbar & Other Bookmarks”. There is our bookmark freshly traded over to the “Bookmarks Toolbar Section”…looking very nice. Conclusion If you are tired of the default “New Tab Page” in Google Chrome then the Incredible StartPage extension will make for a refreshing change.

• Add a non-Google Tasks List to Chrome

  - by Asian Angel

  Most people rely on a task list to help them remember what they need to do but not everyone wants one that is tied to a Google account. If you have been wanting an independent tasks list then join us as we look at the Tasks extension for Google Chrome. Tasks in Action As soon as you have finished installing the extension you are ready to start adding new tasks to your list. Enter your task into the “Text Area” and press “Enter” to add the task to the list. Note: Your tasks list will be retained (in the order you set) when you close and then reopen your browser. In just moments you can have your task list ready to go. Notice that there is also a “numerical indicator” attached to the “Toolbar Button” so that you will always know how many tasks you have left to complete. You can use the “drag and drop” function to rearrange your list into a more proper order if needed. When you are finished with a task all that you will need to do is click on the “Checkmark” to remove it from the list. If you need to make a new entry similar to an existing one simply right click and the text is automatically pasted into the “Text Area”. Make any desired changes and press “Enter” to add your new task to the list. Prefer to skip using the drop-down window? Click on “Tasks” at the top to open your list in a new tab instead. The tasks list looked very nice in our new tab. Being able to use the style that best suits your needs makes this a very convenient extension. Conclusion The Tasks extension is a perfect fit for anyone who needs a tasks list available but does not want to be tied down with an online account. Quick, simple and best of all hassle free.

• Create USB installer from the command line?

  - by j-g-faustus

  I'm trying to create a bootable USB image to install Ubuntu on a new computer. I have done this before following the "create USB drive" instructions for Ubuntu desktop, but I don't have an Ubuntu desktop available. How can I do the same using only the command line? Things I've tried: Create bootable USB on Mac OS X following the ubuntu.com "create USB drive" instructions for Mac: Doesn't boot. usb-creator: According to apt-cache search usb-creator and Wikipedia usb-creator only exists as a graphical tool. "Create manually" instructions at help.ubuntu.com: None of the files and directories described (e.g. casper, filesystem.manifest, menu.lst) exist in the ISO image, and I don't know what has replaced them. unetbootin scripting: Requires X server (graphics support) to run, even when fully scripted. (The command sudo unetbootin lang=en method=diskimage isofile=~/ubuntu-10.10-server-amd64.iso installtype=USB targetdrive=/dev/sdg1 autoinstall=yes gives an error message unetbootin: cannot connect to X server.) Update Also tried GRUB fiddling: Merging information from pendrivelinux.com a related question on the Linux Stackexchange and a grub configuration example I was able to get halfway there - it booted from USB, displayed the grub menu and started the installation, but installation did not complete. For reference, this is the closest I got: sudo su # mount USB pen mount /dev/sd[X]1 /media/usb # install GRUB grub-install --force --no-floppy --root-directory=/media/usb /dev/sd[X] # copy ISO image to USB cp ~/ubuntu-10.10-server-amd64.iso /media/usb # mount ISO image, copy existing grub.cfg mount ~/ubuntu-10.10-server-amd64.iso /media/iso/ -o loop cp /media/iso/boot/grub/grub.cfg /media/usb/boot/grub/ I then edited /media/usb/boot/grub.cfg to add an .iso loopback, example grub entry: menuentry "Install Ubuntu Server" { set gfxpayload=keep loopback loop /ubuntu-10.10-server-amd64.iso linux (loop)/install/vmlinuz file=(loop)/preseed/ubuntu-server.seed iso-scan/filename=/ubuntu-10.10-server-amd64.iso quiet -- initrd (loop)/install/initrd.gz } When booting from USB, this would give me the Grub boot menu and start the installer, but the installer gave up after a couple of screens complaining that it couldn't find the CD-ROM drive. (Naturally, as the box I'm installing on doesn't have an optical drive.) I resolved this particular issue by giving up and doing the "create USB drive" routine using the Ubuntu Live desktop CD (on a computer that does have an optical drive), then the USB install works. But I expect that there is some way to do this from the command line of an Ubuntu system without X server and without an optical drive, so the question still stands. Does anyone know how?

• A big flat text file or a HTML site for language documentation?

  - by Bad Sector

  A project of mine is a small embeddable Tcl-like scripting language, LIL. While i'm mostly making it for my own use, i think it is interesting enough for others to use, so i want it to have a nice (but not very "wordy") documentation. So far i'm using a single flat readme.txt file. It explains the language's syntax, features, standard functions, how to use the C API, etc. Also it is easy to scan and read in almost every environment out there, from basic text-only terminals to full-fledged high-end graphical desktop environments. However, while i tried to keep things nicely formatted (as much as this is possible in plain text), i still think that being a big (and growing) wall of text, it isn't as easy on the eyes as it could be. Also i feel that sometimes i'm not writing as much as i want in order to avoid expanding the text too much. So i thought i could use another project of mine, QuHelp, which is basically a help site generator for sites like this one with a sidebar that provides a tree of topics/subtopics and offline full text search. With this i can use HTML to format the documentation and if i use QuHelp for some other project that uses LIL, i can import LIL's documentation as part of the other project's documentation. However converting the existing documentation to QuHelp/HTML isn't a small task, especially when it comes to functions (i'll need to put more detail on them than what currently exists in the readme.txt file). Also it loses the wide range of availability that it currently has (even if QuHelp's generated code degrades gracefully down to console-only web browsers, plain text is readable from everywhere, including from popular editors such as Vim and Emacs - i had someone once telling me that he likes LIL's documentation because it is readable without leaving his editor). So, my question is simply this: should i keep the documentation as it is now in the form of a single readme.txt file or should i convert it to something like the site i mentioned above? There is also the option to do both, but i'm not sure if i'll be able to always keep them in sync or if it is worth the effort. After asking around in IRC i've got mixed answers: some liked the wide availability of the single text file, others said that it is looks as bad as a man page (personally i don't mind that - i can read man pages just fine - but other people might have issues reading them). What do you think?

• NRF Big Show 2011 -- Part 2

  - by David Dorf

  One of the things I love about attending NRF is visiting the smaller booths to see what new innovative ideas have sprung up. After all, by watching emerging technologies we can get a sense of how the retail experience might change. After NRF I'm hoping to write a post on what I found, if anything, so be sure to check back. At the Oracle Retail booth we'll be demonstrating some of the aspects of the changing retail experience. These demos use a mix of GA and experimental components. Here are some highlights: 1. Checkin We wrote a consumer iPhone app we call Store Gateway that lets consumers access information from the store. They'll start by doing a checkin when they arrive that will alert the store manager via another iPhone app we wrote called Mobile Manager. Additionally, we display a welcome messaging using Starmount's digital sign. 2. Receive Offers There are three interaction points where a store can easily make an offer to a consumer: checkin, product scans, and checkout. For this demo we're calling our Universal Offer Engine at checkin to determine the best offer for this particular consumer. This offer is then displayed on the consumer's phone as well as on the digital sign. 3. Scan Products To thwart consumers from scanning product barcodes, we used Store Inventory Management to print QRCodes on shelf label then provided access to a scanner in the Store Gateway iphone app. When the consumer scans the shelf label they are shown product information provided by the retailer. 4. Checkout While we don't have a NFC-enabled mobile phone, we have a NFC chip that can attach to a phone. We're using this to checkout using a reader provided by ViVOTech. Tap the phone on the reader, and the POS accesses the customer#, coupons, and payment information. This really speeds the checkout process. 5. Digital Receipt After the transaction is complete, a digital copy of the receipt is sent to Intuit's QuickReceipts where consumers to store all their digital receipts. There's even an iPhone app that provides easy access to the receipts. This covers about half of what what we'll be showing, so be sure to stop by. I'll also be talking about how mobile is impacting the retail experience at the Wednesday morning session NRF Mobile Retail Initiative: a Blueprint for Action. See you at the Big Show!

• Play a Webpage Display Prank in Google Chrome

  - by Asian Angel

  Are you looking for a fun but innocent prank to play on someone who loves using Google Chrome? If so then you may want to have a closer look at the Upside Down extension for Chrome. Before Here is our example webpage before starting the prank…looking all “normal like”. Upside Down in Action As soon as the extension has been installed you are ready to go. If you had a webpage open before installing the extension you will only need to refresh the page. As soon as the page has been refreshed or a new one is opened everything is going to look messed up very quickly. With the default setting there are five different “looks” available. To cycle through the five “looks” use the “Windows Key + Semicolon” or “Command + Semicolon” to toggle through them. On the sixth toggle the webpage will revert to normal (toggling afterwards starts the whole process again). Here are the five “looks” available…         Options There are options available for the extension where you can focus on just a specific effect or a group of effects. You can also enable a “Grayscale Effect” and even set a delay timer (a definite “evil touch”)! Think of the fun and surprised looks that await… Conclusion If you have been looking for a fun and unexpected prank for your favorite Google Chrome fan then this just might be what you have been looking for.

• Stop Saying "Multi-Channel!"

  - by David Dorf

  I keep hearing the term "multi-channel" in our industry, but its time to move on. It kinda reminds me of the term "ECR" or electronic cash register. Long ago ECR was a leading-edge term, but nowadays its rarely used because its table-stakes. After all, what cash register today isn't electronic? The same logic applies to multi-channel, at least when we're talking about tier-1 and tier-2 retailers. If you're still talking about multi-channel retailing, you're in big trouble. Some have switched over to the term "cross-channel," and that's a step in the right direction but still falls short. Its kinda like saying, "I upgraded my ECR to accept debit cards!" Yawn. Who hasn't? Today's retailers need to focus on omni-channel, which I first heard from my friends over at RSR but was originally coined at IDC. First retailers added e-commerce to their store and catalog channels yielding multi-channel retailing. Consumers could use the channel that worked best for them. Then some consumers wanted to combine channels with features like buy-on-the-Web, pickup-in-the-store. Thus began the cross-channel initiatives to breakdown the silos and enable the channels to communicate with each other. But the multi-channel architecture is full of duplication that thwarts efforts of providing a consistent experience. Each has its own cart, its own pricing, and often its own CRM. This was an outcrop of trying to bring the independent channels to market quickly. Rather than reusing and rebuilding existing components to meet the new demands, silos were created that continue to exist today. Today's consumers want omni-channel retailing. They want to interact with brands in a consistent manner that is channel transparent, yet optimized for that particular interaction. The diagram below, from the soon-to-be-released NRF Mobile Blueprint v2, shows this progression. For retailers to provide an omni-channel experience, there needs to be one logical representation of products, prices, promotions, and customers across all channels. The only thing that varies is the presentation of the content based on the delivery mechanism (e.g. shelf labels, mobile phone, web site, print, etc.) and often these mechanisms can be combined in various ways. I'm looking forward to the day in which I can use my phone to scan QR-codes in a catalog to create a shopping cart of items. Then do some further research on the retailer's Web site and be told about related items that might interest me. Be able to easily solicit opinions and reviews from social sites, and finally enter the store to pickup my items, knowing that any applicable coupons have been applied. In this scenario, I the consumer are dealing with a single brand that is aware of me and my needs throughout the entire transaction. Nirvana.

• New Oracles VM RAC template with support for oracle vm 3 built-in

  - by wcoekaer

  The RAC team did it again (thanks Saar!) - another awesome set of Oracle VM templates published and uploaded to My Oracle Support. You can find the main page here. What's special about the latest version of DeployCluster is that it integrates tightly with Oracle VM 3 manager. It basically is an Oracle VM frontend that helps start VMs, pass arguments down automatically and there is absolutely no need to log into the Oracle VM servers or the guests. Once it completes, you have an entire Oracle RAC database setup ready to go. Here's a short summary of the steps : Set up an Oracle VM 3 server pool Download the Oracle VM RAC template from oracle.com Import the template into Oracle VM using Oracle VM Manager repository - import Create a public and private network in Oracle VM Manager in the network tab Configure the template with the right public and private virtual networks Create a set of shared disks (physical or virtual) to assign to the VMs you want to create (for ASM/at least 5) Clone a set of VMs from the template (as many RAC nodes as you plan to configure) With Oracle VM 3.1 you can clone with a number so one clone command for, say 8 VMs is easy. Assign the shared devices/disks to the cloned VMs Create a netconfig.ini file on your manager node or a client where you plan to run DeployCluster This little text file just contains the IP addresses, hostnames etc for your cluster. It is a very simple small textfile. Run deploycluster.py with the VM names as argument Done. At this point, the tool will connect to Oracle VM Manager, start the VMs and configure each one, Configure the OS (Oracle Linux) Configure the disks with ASM Configure the clusterware (CRS) Configure ASM Create database instances on each node. Now you are ready to log in, and use your x node database cluster. x No need to download various products from various websites, click on trial licenses for the OS, go to a Virtual Machine store with sample and test versions only - this is production ready and supported. Software. Complete. example netconfig.ini : # Node specific information NODE1=racnode1 NODE1VIP=racnode1-vip NODE1PRIV=racnode1-priv NODE1IP=192.168.1.2 NODE1VIPIP=192.168.1.22 NODE1PRIVIP=10.0.0.22 NODE2=racnode2 NODE2VIP=racnode2-vip NODE2PRIV=racnode2-priv NODE2IP=192.168.1.3 NODE2VIPIP=192.168.1.23 NODE2PRIVIP=10.0.0.23 # Common data PUBADAP=eth0 PUBMASK=255.255.255.0 PUBGW=192.168.1.1 PRIVADAP=eth1 PRIVMASK=255.255.255.0 RACCLUSTERNAME=raccluster DOMAINNAME=mydomain.com DNSIP= # Device used to transfer network information to second node # in interview mode NETCONFIG_DEV=/dev/xvdc # 11gR2 specific data SCANNAME=racnode12-scan SCANIP=192.168.1.50

• how to convert avi (xvid) to mkv or mp4 (h264)

  - by bcsteeve

  Very noob when it comes to video. I'm trying to make sense of what I"m finding via Google... but its mostly Greek to me. I have a bunch of Avi files that won't play in my WD TV Play box. Mediainfo tells me they are xvid. Specs for the box show that should be fine... but digging through forums says its hit-and-miss. So I'd like to try converting them to h264 encoded MKV or mp4 files. I gather avconv is the tool, but reading the manual just has me really really confused. I tried the very basic example of: avconv -i file.avi -c copy file.mp4 it took less than 4 seconds. And it worked... sort of. It "played" in that something came up on the screen... but there was horrible artifacting and scenes would just sort of melt into each other. I want to preserve quality if possible. I'm not concerned about file size. I'm not terribly concerned with the time it takes either, provided I can do them in a batch. Can someone familiar with the process please give me a command with the options? Thank you for your help. I'm posting the mediainfo in case it helps: General Complete name : \\SERVER\Video\Public\test.avi Format : AVI Format/Info : Audio Video Interleave File size : 189 MiB Duration : 11mn 18s Overall bit rate : 2 335 Kbps Writing application : Lavf52.32.0 Video ID : 0 Format : MPEG-4 Visual Format profile : Advanced Simple@L5 Format settings, BVOP : 2 Format settings, QPel : No Format settings, GMC : No warppoints Format settings, Matrix : Default (H.263) Muxing mode : Packed bitstream Codec ID : XVID Codec ID/Hint : XviD Duration : 11mn 18s Bit rate : 2 129 Kbps Width : 720 pixels Height : 480 pixels Display aspect ratio : 16:9 Frame rate : 29.970 fps Standard : NTSC Color space : YUV Chroma subsampling : 4:2:0 Bit depth : 8 bits Scan type : Progressive Compression mode : Lossy Bits/(Pixel*Frame) : 0.206 Stream size : 172 MiB (91%) Writing library : XviD 1.2.1 (UTC 2008-12-04) Audio ID : 1 Format : MPEG Audio Format version : Version 1 Format profile : Layer 3 Mode : Joint stereo Mode extension : MS Stereo Codec ID : 55 Codec ID/Hint : MP3 Duration : 11mn 18s Bit rate mode : Constant Bit rate : 192 Kbps Channel(s) : 2 channels Sampling rate : 48.0 KHz Compression mode : Lossy Stream size : 15.5 MiB (8%) Alignment : Aligned on interleaves Interleave, duration : 24 ms (0.72 video frame)

• How do we keep dependent data structures up to date?

  - by Geo

  Suppose you have a parse tree, an abstract syntax tree, and a control flow graph, each one logically derived from the one before. In principle it is easy to construct each graph given the parse tree, but how can we manage the complexity of updating the graphs when the parse tree is modified? We know exactly how the tree has been modified, but how can the change be propagated to the other trees in a way that doesn't become difficult to manage? Naturally the dependent graph can be updated by simply reconstructing it from scratch every time the first graph changes, but then there would be no way of knowing the details of the changes in the dependent graph. I currently have four ways to attempt to solve this problem, but each one has difficulties. Nodes of the dependent tree each observe the relevant nodes of the original tree, updating themselves and the observer lists of original tree nodes as necessary. The conceptual complexity of this can become daunting. Each node of the original tree has a list of the dependent tree nodes that specifically depend upon it, and when the node changes it sets a flag on the dependent nodes to mark them as dirty, including the parents of the dependent nodes all the way down to the root. After each change we run an algorithm that is much like the algorithm for constructing the dependent graph from scratch, but it skips over any clean node and reconstructs each dirty node, keeping track of whether the reconstructed node is actually different from the dirty node. This can also get tricky. We can represent the logical connection between the original graph and the dependent graph as a data structure, like a list of constraints, perhaps designed using a declarative language. When the original graph changes we need only scan the list to discover which constraints are violated and how the dependent tree needs to change to correct the violation, all encoded as data. We can reconstruct the dependent graph from scratch as though there were no existing dependent graph, and then compare the existing graph and the new graph to discover how it has changed. I'm sure this is the easiest way because I know there are algorithms available for detecting differences, but they are all quite computationally expensive and in principle it seems unnecessary so I'm deliberately avoiding this option. What is the right way to deal with these sorts of problems? Surely there must be a design pattern that makes this whole thing almost easy. It would be nice to have a good solution for every problem of this general description. Does this class of problem have a name?
