• ListView - Index and Position Behavior upon restart()

  - by tunneling

  I am using a ListView with an ArrayAdapter that holds objects. When I select an item, I am capturing the position and index of the selected item. If I scroll down prior to selection, the position and index represent the location of the item in the list. Selecting that items takes me to another activity. When I use the back button to return to the list, it seems that the ListView get's a new position and index for the visible items. As a result, I can't figure out how to reference the selected item during the restart() of the ListView Activity. I have tried to caputure position and index, but as I've said, they change upon returning to the Activity. Is my understanding of the ListView "redraw" correct? Does it renumber my items based on what's visible? -When in the life cycle is getView() called? Is there a way to force an update to the ListView so that my caputured index still points to the same object? Thanks, Jason

• Magento layout related basic Questions ?

  - by user197992

  Here is what I think about Magento (plz correct me if I am wrong ) 1)Each module has its own layout.xml stored in /interface/theme/layouts/ folder. 2)Magento loads all these layouts for current theme and creates a big xml file. Now what I am confused at . a)If magento loads /default/default/ (interface & theme) then why all the templates & layouts are inside base/default/ ?? b)what if I create my module name “page” inside my namespace “Jason” i.e Jason_Page , now what will happen to blocks in layout files which are named c)Since all the layouts are loaded and merged into one big xml file , then what happen to all those reference blocks which have same name attribute and are inside “Default” handle tag ? e.g d)what is Local.xml layout for and its use ?? e)wats the relation ship between a module name foo , and its layout name foo.xml ? What will happen to layout.xml if two modules with same name exist in diff namespace ? Thanks in advance .

• Exchange Server 2010: move mailboxes from recoveded and mounted edb to user's mailbox [closed]

  - by Cook

  One of our exchange servers crashed, and I am trying to recover the mailboxes. We had 1 exchange 2003 server named "apex" and 1 exchange 2010 server named "2008Enterprise. the exchange 2010 server named "2008Enterprise" crashed. I created a new exchange 2010 server named "Providence". I ran the command on Providence: New-MailboxDatabase -Recovery -Name JBCMail -Server Providence -EdbFilePath "c:\data\Exchange\Mailbox\Mailbox Database 0579285147\Mailbox Database 0579285147.edb" -LogFolderPath "c:\data\Exchange\Mailbox\Mailbox Database 0579285147" this command executed and finished without error I then ran the command: eseutil /p E00 this command was executed from the below directory: c:\data\Exchange\Mailbox\Mailbox Database 0579285147 I then mounted the JBCMail with the mount command note: I do not have my full typed command. Inside my Exchange Management Console (EMC) I can view the new mailbox database named JBCMail. The JBCMail database is show as mounted on the exchange server named Providence. I can see the crashed Exchange server named 2008Exchange. In the EMC the crashed exchange server states the Copy Status under ServerConfiguration-Mailbox is ServiceDown. From here I need to recover three mailboxes The mail boxes are on the apex server. How do I move the mailboxs from apex to Providence? How do I restore the mailboxes from JBCmail mounted database to the user's mailbox? I do not fully understand how to use the Restore-Mailbox command because when I use this command it tries to restore the mailbox to the dead apex server.

• jquery $.ajax load in UI dialog() problem

  - by alex

  i have a working bing Image search api with jsonp datatype. It's working with no problems. When i load the image search script in a Jquery UI dialog, it display properly and i'm able to search and see the results in the dialog() box. But if i close the dialog() and open it again, now if i search no results show. Looking at console.log, i do confirm the jason data is recieved, but for some reason it's not appending to the result div, so i see no result on the screen. This onyl happens if i close the dialog and open it again. If i refresh refresh the page and open the dialog again then search results are displayed. This is what i'm using to append the results. $.each(data.SearchResponse.Image.Results, function(i, item) { console.log(item.Thumbnail.Url); $("#Results").append("<li><img style='width:100px; height:75px;' src='" + item.Thumbnail.Url + "'/></li>"); });

• How to Use Windows’ Advanced Search Features: Everything You Need to Know

  - by Chris Hoffman

  You should never have to hunt down a lost file on modern versions of Windows — just perform a quick search. You don’t even have to wait for a cartoon dog to find your files, like on Windows XP. The Windows search indexer is constantly running in the background to make quick local searches possible. This enables the kind of powerful search features you’d use on Google or Bing — but for your local files. Controlling the Indexer By default, the Windows search indexer watches everything under your user folder — that’s C:\Users\NAME. It reads all these files, creating an index of their names, contents, and other metadata. Whenever they change, it notices and updates its index. The index allows you to quickly find a file based on the data in the index. For example, if you want to find files that contain the word “beluga,” you can perform a search for “beluga” and you’ll get a very quick response as Windows looks up the word in its search index. If Windows didn’t use an index, you’d have to sit and wait as Windows opened every file on your hard drive, looked to see if the file contained the word “beluga,” and moved on. Most people shouldn’t have to modify this indexing behavior. However, if you store your important files in other folders — maybe you store your important data a separate partition or drive, such as at D:\Data — you may want to add these folders to your index. You can also choose which types of files you want to index, force Windows to rebuild the index entirely, pause the indexing process so it won’t use any system resources, or move the index to another location to save space on your system drive. To open the Indexing Options window, tap the Windows key on your keyboard, type “index”, and click the Indexing Options shortcut that appears. Use the Modify button to control the folders that Windows indexes or the Advanced button to control other options. To prevent Windows from indexing entirely, click the Modify button and uncheck all the included locations. You could also disable the search indexer entirely from the Programs and Features window. Searching for Files You can search for files right from your Start menu on Windows 7 or Start screen on Windows 8. Just tap the Windows key and perform a search. If you wanted to find files related to Windows, you could perform a search for “Windows.” Windows would show you files that are named Windows or contain the word Windows. From here, you can just click a file to open it. On Windows 7, files are mixed with other types of search results. On Windows 8 or 8.1, you can choose to search only for files. If you want to perform a search without leaving the desktop in Windows 8.1, press Windows Key + S to open a search sidebar. You can also initiate searches directly from Windows Explorer — that’s File Explorer on Windows 8. Just use the search box at the top-right of the window. Windows will search the location you’ve browsed to. For example, if you’re looking for a file related to Windows and know it’s somewhere in your Documents library, open the Documents library and search for Windows. Using Advanced Search Operators On Windows 7, you’ll notice that you can add “search filters” form the search box, allowing you to search by size, date modified, file type, authors, and other metadata. On Windows 8, these options are available from the Search Tools tab on the ribbon. These filters allow you to narrow your search results. If you’re a geek, you can use Windows’ Advanced Query Syntax to perform advanced searches from anywhere, including the Start menu or Start screen. Want to search for “windows,” but only bring up documents that don’t mention Microsoft? Search for “windows -microsoft”. Want to search for all pictures of penguins on your computer, whether they’re PNGs, JPEGs, or any other type of picture file? Search for “penguin kind:picture”. We’ve looked at Windows’ advanced search operators before, so check out our in-depth guide for more information. The Advanced Query Syntax gives you access to options that aren’t available in the graphical interface. Creating Saved Searches Windows allows you to take searches you’ve made and save them as a file. You can then quickly perform the search later by double-clicking the file. The file functions almost like a virtual folder that contains the files you specify. For example, let’s say you wanted to create a saved search that shows you all the new files created in your indexed folders within the last week. You could perform a search for “datecreated:this week”, then click the Save search button on the toolbar or ribbon. You’d have a new virtual folder you could quickly check to see your recent files. One of the best things about Windows search is that it’s available entirely from the keyboard. Just press the Windows key, start typing the name of the file or program you want to open, and press Enter to quickly open it. Windows 8 made this much more obnoxious with its non-unified search, but unified search is finally returning with Windows 8.1.

• ASP.NET MVC HandleError Attribute

  - by Ben Griswold

  Last Wednesday, I took a whopping 15 minutes out of my day and added ELMAH (Error Logging Modules and Handlers) to my ASP.NET MVC application.  If you haven’t heard the news (I hadn’t until recently), ELMAH does a killer job of logging and reporting nearly all unhandled exceptions.  As for handled exceptions, I’ve been using NLog but since I was already playing with the ELMAH bits I thought I’d see if I couldn’t replace it. Atif Aziz provided a quick solution in his answer to a Stack Overflow question.  I’ll let you consult his answer to see how one can subclass the HandleErrorAttribute and override the OnException method in order to get the bits working.  I pretty much took rolled the recommended logic into my application and it worked like a charm.  Along the way, I did uncover a few HandleError fact to which I wasn’t already privy.  Most of my learning came from Steven Sanderson’s book, Pro ASP.NET MVC Framework.  I’ve flipped through a bunch of the book and spent time on specific sections.  It’s a really good read if you’re looking to pick up an ASP.NET MVC reference. Anyway, my notes are found a comments in the following code snippet.  I hope my notes clarify a few things for you too. public class LogAndHandleErrorAttribute : HandleErrorAttribute {     public override void OnException(ExceptionContext context)     {         // A word from our sponsors:         //      http://stackoverflow.com/questions/766610/how-to-get-elmah-to-work-with-asp-net-mvc-handleerror-attribute         //      and Pro ASP.NET MVC Framework by Steven Sanderson         //         // Invoke the base implementation first. This should mark context.ExceptionHandled = true         // which stops ASP.NET from producing a "yellow screen of death." This also sets the         // Http StatusCode to 500 (internal server error.)         //         // Assuming Custom Errors aren't off, the base implementation will trigger the application         // to ultimately render the "Error" view from one of the following locations:         //         //      1. ~/Views/Controller/Error.aspx         //      2. ~/Views/Controller/Error.ascx         //      3. ~/Views/Shared/Error.aspx         //      4. ~/Views/Shared/Error.ascx         //         // "Error" is the default view, however, a specific view may be provided as an Attribute property.         // A notable point is the Custom Errors defaultRedirect is not considered in the redirection plan.         base.OnException(context);           var e = context.Exception;                  // If the exception is unhandled, simply return and let Elmah handle the unhandled exception.         // Otherwise, try to use error signaling which involves the fully configured pipeline like logging,         // mailing, filtering and what have you). Failing that, see if the error should be filtered.         // If not, the error simply logged the exception.         if (!context.ExceptionHandled                || RaiseErrorSignal(e)                   || IsFiltered(context))                  return;           LogException(e); // FYI. Simple Elmah logging doesn't handle mail notifications.     }

• No, iCloud Isn’t Backing Them All Up: How to Manage Photos on Your iPhone or iPad

  - by Chris Hoffman

  Are the photos you take with your iPhone or iPad backed up in case you lose your device? If you’re just relying on iCloud to manage your important memories, your photos may not be backed up at all. Apple’s iCloud has a photo-syncing feature in the form of “Photo Stream,” but Photo Stream doesn’t actually perform any long-term backups of your photos. iCloud’s Photo Backup Limitations Assuming you’ve set up iCloud on your iPhone or iPad, your device is using a feature called “Photo Stream” to automatically upload the photos you take to your iCloud storage and sync them across your devices. Unfortunately, there are some big limitations here. 1000 Photos: Photo Stream only backs up the latest 1000 photos. Do you have 1500 photos in your Camera Roll folder on your phone? If so, only the latest 1000 photos are stored in your iCloud account online. If you don’t have those photos backed up elsewhere, you’ll lose them when you lose your phone. If you have 1000 photos and take one more, the oldest photo will be removed from your iCloud Photo Stream. 30 Days: Apple also states that photos in your Photo Stream will be automatically deleted after 30 days “to give your devices plenty of time to connect and download them.” Some people report photos aren’t deleted after 30 days, but it’s clear you shouldn’t rely on iCloud for more than 30 days of storage. iCloud Storage Limits: Apple only gives you 5 GB of iCloud storage space for free, and this is shared between backups, documents, and all other iCloud data. This 5 GB can fill up pretty quickly. If your iCloud storage is full and you haven’t purchased any more storage more from Apple, your photos aren’t being backed up. Videos Aren’t Included: Photo Stream doesn’t include videos, so any videos you take aren’t automatically backed up. It’s clear that iCloud’s Photo Stream isn’t designed as a long-term way to store your photos, just a convenient way to access recent photos on all your devices before you back them up for real. iCloud’s Photo Stream is Designed for Desktop Backups If you have a Mac, you can launch iPhoto and enable the Automatic Import option under Photo Stream in its preferences pane. Assuming your Mac is on and connected to the Internet, iPhoto will automatically download photos from your photo stream and make local backups of them on your hard drive. You’ll then have to back up your photos manually so you don’t lose them if your Mac’s hard drive ever fails. If you have a Windows PC, you can install the iCloud Control Panel, which will create a Photo Stream folder on your PC. Your photos will be automatically downloaded to this folder and stored in it. You’ll want to back up your photos so you don’t lose them if your PC’s hard drive ever fails. Photo Stream is clearly designed to be used along with a desktop application. Photo Stream temporarily backs up your photos to iCloud so iPhoto or iCloud Control Panel can download them to your Mac or PC and make a local backup before they’re deleted. You could also use iTunes to sync your photos from your device to your PC or Mac, but we don’t really recommend it — you should never have to use iTunes. How to Actually Back Up All Your Photos Online So Photo Stream is actually pretty inconvenient — or, at least, it’s just a way to temporarily sync photos between your devices without storing them long-term. But what if you actually want to automatically back up your photos online without them being deleted automatically? The solution here is a third-party app that does this for you, offering the automatic photo uploads with long-term storage. There are several good services with apps in the App Store: Dropbox: Dropbox’s Camera Upload feature allows you to automatically upload the photos — and videos — you take to your Dropbox account. They’ll be easily accessible anywhere there’s a Dropbox app and you can get much more free Dropbox storage than you can iCloud storage. Dropbox will never automatically delete your old photos. Google+: Google+ offers photo and video backups with its Auto Upload feature, too. Photos will be stored in your Google+ Photos — formerly Picasa Web Albums — and will be marked as private by default so no one else can view them. Full-size photos will count against your free 15 GB of Google account storage space, but you can also choose to upload an unlimited amount of photos at a smaller resolution. Flickr: The Flickr app is no longer a mess. Flickr offers an Auto Upload feature for uploading full-size photos you take and free Flickr accounts offer a massive 1 TB of storage for you to store your photos. The massive amount of free storage alone makes Flickr worth a look. Use any of these services and you’ll get an online, automatic photo backup solution you can rely on. You’ll get a good chunk of free space, your photos will never be automatically deleted, and you can easily access them from any device. You won’t have to worry about storing local copies of your photos and backing them up manually. Apple should fix this mess and offer a better solution for long-term photo backup, especially considering the limitations aren’t immediately obvious to users. Until they do, third-party apps are ready to step in and take their place. You can also automatically back up your photos to the web on Android with Google+’s Auto Upload or Dropbox’s Camera Upload.

• How to Access a Windows Desktop From Your Tablet or Phone

  - by Chris Hoffman

  iPads and Android tablets can’t run Windows apps locally, but they can access a Windows desktops remotely — even with a physical keyboard. In a pinch, the same tricks can be used to access a Windows desktop from a smartphone. Microsoft recently launched their own official Remote Desktop app for iOS and Android devices. Microsoft’s official apps are primarily useful for businesses — if you’re a typical home user, you’ll want to use a different remote desktop solution. Microsoft’s Remote Desktop App Microsoft now offers official Remote Desktop apps for iPad and iPhone as well as Android tablets and smartphones. The apps use Microsoft’s RDP protocol to connect to remote Windows systems. They’re essentially just new clients for the Remote Desktop feature that has been included in Windows for more than a decade. There are big problems with these apps if you’re an average home user. Microsoft’s Remote Desktop server is not available on standard or Home versions of Windows, only Professional and Enterprise editions. If you do have the appropriate edition of Windows, you’ll have to set up port-forwarding and a dynamic DNS service if you want to access your Windows desktop from outside your local network. You could also set up a VPN — either way you’ll need to do some footwork. This app is a gift to businesses who are already using Remote Desktop and enthusiasts who have the more expensive versions of Windows and don’t mind the configuration process. To set this up, follow our guide to setting up Remote Desktop for Internet access and connect using the Remote Desktop app instead of traditional Remote Desktop clients. TeamViewer If you have the standard edition of Windows or you just don’t want to mess around with port-forwarding and dynamic DNS configuration, you’ll want to skip Remote Desktop and use something else. We like TeamViewer for this. Just as it’s a great way to remotely troubleshoot your relatives’ computers, it’s also a great way to remotely access your own computer. It doesn’t have the same limitations Microsoft’s Remote Desktop system has — it’s completely free for personal use, runs on any edition of Windows, and is easy to set up. There’s no messing around with port-forwarding or dynamic DNS configuration. To get started, just download and run the TeamViewer program on your computer. You can get started with it immediately, but you’ll want to set up unattended access to connect remotely without using the codes displayed on your screen. To connect, just install the TeamViewer mobile app and log in with the details the TeamViewer window displays. TeamViewer also offers software that runs on Mac and Linux, so you can remote-control other types of computers from your tablet. Other Options Microsoft’s Remote Desktop app and TeamViewer aren’t the only options, of course. There are a variety of different apps and services built for this. Splashtop is another fairly popular remote desktop solution that some people report as being faster. Unfortunately, it’s not entirely free — the iPad and iPhone app costs $20 at regular price. To use it over the Internet, you’ll have to purchase an additional “Anywhere Access Pack.” If you’re frustrated with TeamViewer’s speed and you don’t mind spending money, you may want to try Splashtop instead. As always, you could use any VNC server along with a VNC client app. VNC is the do-it-yourself solution — it’s an open protocol. Unlike Microsoft’s RDP protocol, you can install a VNC server of your own, configure it how you like, and use any mobile VNC client app. This is more flexible because you can install a VNC server on any edition of Windows or even non-Windows operating systems, but it otherwise has all the same issues — you have to worry about port-forwarding, setting up dynamic DNS, and securing your VNC server. Keep an eye on Chrome Remote Desktop. Chrome already offers a built-in remote desktop feature that allows you to remotely control your PC from another Windows, Mac, Linux, or Chrome OS device. Google is rumored to be building an Android app for Chrome Remote Desktop, which would allow you to easily access a computer running Chrome from Android tablets. Google’s solution is much more user-friendly for average people than Microsoft’s Remote Desktop solution, which is clearly geared towards businesses. Chrome Remote Desktop just requires signing in with a Google account. Remote desktop solutions like Microsoft’s Remote Desktop app and TeamViewer are also available for Windows tablets. On Windows RT devices like the Surface RT and Surface 2, they allow you to use the full Windows desktop that’s unavailable on your tablet.

• SQL Developer Data Modeler v3.3 Early Adopter: Collaborative Design via Excel?

  - by thatjeffsmith

  As you may have heard last week, we have a new version of Oracle SQL Developer Data Modeler now available as an Early Adopter release. Version 3.3 has quite a few new features and I’ll be previewing them here. Today’s topic is our new Excel integration. It builds off of last week’s lesson: Search, so you may want to go read that first. They say it takes a village to raise a child. I say it takes a team to build a data model. You have your techie folks, your business folks, your in-betweeners, and your database geeks. Who gets to define how customers are represented and stored in your database? That data lives forever, so you better get it right from the beginning, or you’ll be living in a hacker’s paradise for years to come. Lots of good rantings, ravings, and advice on this topic in general on Karen Lopez’s (@datachick) blog. But let’s say you are the primary modeler on a project. You dutifully interview the business folks for their requirements. You sit down and start to model and think you’re pretty close. Now you need someone to confirm your assumptions and provide some feedback. Do you send your model over? Take a screenshot and blow it up on a whiteboard? Export to HTML and let them take a magic marker to their monitors? Or maybe you bite the bullet and install your modeling software on their desktops and take the hours or days required to train them up on how to use the the tool. Wouldn’t it be nice if they could just mark up their corrections in Excel and let you suck the updates back in? This is what we have started to build in Oracle SQL Developer Data Modeler. Let’s say you have a new table called ‘UT_STARTUPS.’ It looks a little something like this: A table in Oracle SQL Developer Data Modeler What I would like to do is have my team or co-worker review how I have defined those columns. Perhaps TIMESTAMP is overkill or maybe the column names themselves aren’t up to snuff. What I am going to do is now search for all the columns in my table, then export that to Excel. So do a search for UT_STARTUPS. Search, filter, then Report With the filter set to ‘Columns,’ if I do a report I’ll be only getting the columns that are resolving to my search term. So as long as my table name is unique in the model, I should get what I’m looking for. Here’s what I see when I click on the Report button: XLS or XLSX, either format is just fine I want to decide how the Column data is exported to Excel though, so I’m going to create a report template that I can use going forward. So click the ‘Manage’ button and setup a new template. I’m going to call mine ‘CollaborativeDevelopment.’ The templates allow me to define what properties are included in the reports. Once this is set, I’ll have the XLS file generated, and get to work Now let the Excel junkies do their stuff Note that not ALL of the report properties are update-able (yes, I made up a new word there) via Excel. We’ll have the full list of properties documented going forward, but in my Excel sheet, note that I can’t change the table name or the data types for the columns. I’m going to update some column names and supply ‘nice’ comments so the database users know what’s what. Here’s my input for the designer/architect/database dude: Be kind, please rew…use comments. Save the file, email it back to your modeler. Update the model from Excel That’s right, it’s a right mouse click from your model in the tree If everything goes right, you’ll see a nice confirmation message: It’s alive! Another to-do item on tap – making this dialog more informative. We’ll be showing exactly what in your model was updated from Excel. Let’s take another look at the model now Voila! Why are we doing this again? The goal is to reduce the number of round-trips from the modeler and the business process owner. One is used to working with Excel – why not allow them to mark up their changes in the tool they already know? This is an early adopter release and I anticipate this feature getting a good bit of tuning up before we release. Why don’t you download 3.3, give it a whirl, and let us know what you think?

• How to Sync Any Folder With SkyDrive on Windows 8.1

  - by Chris Hoffman

  Before Windows 8.1, it was possible to sync any folder on your computer with SkyDrive using symbolic links. This method no longer works now that SkyDrive is baked into Windows 8.1, but there are other tricks you can use. Creating a symbolic link or directory junction inside your SkyDrive folder will give you an empty folder in your SkyDrive cloud storage. Confusingly, the files will appear inside the SkyDrive Modern app as if they were being synced, but they aren’t. The Solution With SkyDrive refusing to understand and accept symbolic links in its own folder, the best option is probably to use symbolic links anyway — but in reverse. For example, let’s say you have a program that automatically saves important data to a folder anywhere on your hard drive — whether it’s C:\Users\USER\Documents\, C:\Program\Data, or anywhere else. Rather than trying to trick SkyDrive into understanding a symbolic link, we could instead move the actual folder itself to SkyDrive and then use a symbolic link at the folder’s original location to trick the original program. This may not work for every single program out there. But it will likely work for most programs, which use standard Windows API calls to access folders and save files. We’re just flipping the old solution here — we can’t trick SkyDrive anymore, so let’s try to trick other programs instead. Moving a Folder and Creating a Symbolic Link First, ensure no program is using the external folder. For example, if it’s a program data or settings folder, close the program that’s using the folder. Next, simply move the folder to your SkyDrive folder. Right-click the external folder, select Cut, go to the SkyDrive folder, right-click and select Paste. The folder will now be located in the SkyDrive folder itself, so it will sync normally. Next, open a Command Prompt window as Administrator. Right-click the Start button on the taskbar or press Windows Key + X and select Command Prompt (Administrator) to open it. Run the following command to create a symbolic link at the original location of the folder: mklink /d “C:\Original\Folder\Location” “C:\Users\NAME\SkyDrive\FOLDERNAME\” Enter the correct paths for the exact location of the original folder and the current location of the folder in your SkyDrive. Windows will then create a symbolic link at the folder’s original location. Most programs should hopefully be tricked by this symbolic location, saving their files directly to SkyDrive. You can test this yourself. Put a file into the folder at its original location. It will be saved to SkyDrive and sync normally, appearing in your SkyDrive storage online. One downside here is that you won’t be able to save a file onto SkyDrive without it taking up space on the same hard drive SkyDrive is on. You won’t be able to scatter folders across multiple hard drives and sync them all. However, you could always change the location of the SkyDrive folder on Windows 8.1 and put it on a drive with a larger amount of free space. To do this, right-click the SkyDrive folder in File Explorer, select Properties, and use the options on the Location tab. You could even use Storage Spaces to combine the drives into one larger drive. Automatically Copy the Original Files to SkyDrive Another option would be to run a program that automatically copies files from another folder on your computer to your SkyDrive folder. For example, let’s say you want to sync copies of important log files that a program creates in a specific folder. You could use a program that allows you to schedule automatic folder-mirroring, configuring the program to regularly copy the contents of your log folder to your SkyDrive folder. This may be a useful alternative for some use cases, although it isn’t the same as standard syncing. You’ll end up with two copies of the files taking up space on your system, which won’t be ideal for large files. The files also won’t be instantly uploaded to your SkyDrive storage after they’re created, but only after the scheduled task runs. There are many options for this, including Microsoft’s own SyncToy, which continues to work on Windows 8. If you were using the symbolic link trick to automatically sync copies of PC game save files with SkyDrive, you could just install GameSave Manager. It can be configured to automatically create backup copies of your computer’s PC game save files on a schedule, saving them to SkyDrive where they’ll be synced and backed up online. SkyDrive support was completely rewritten for Windows 8.1, so it’s not surprising that this trick no longer works. The ability to use symbolic links in previous versions of SkyDrive was never officially supported, so it’s not surprising to see it break after a rewrite. None of the methods above are as convenient and quick as the old symbolic link method, but they’re the best we can do with the SkyDrive integration Microsoft has given us in Windows 8.1. It’s still possible to use symbolic links to easily sync other folders with competing cloud storage services like Dropbox and Google Drive, so you may want to consider switching away from SkyDrive if this feature is critical to you.

• How to Play PC Games on Your TV

  - by Chris Hoffman

  No need to wait for Valve’s Steam Machines — connect your Windows gaming PC to your TV and use powerful PC graphics in the living room today. It’s easy — you don’t need any unusual hardware or special software. This is ideal if you’re already a PC gamer who wants to play your games on a larger screen. It’s also convenient if you want to play multiplayer PC games with controllers in your living rom. HDMI Cables and Controllers You’ll need an HDMI cable to connect your PC to your television. This requires a TV with HDMI-in, a PC with HDMI-out, and an HDMI cable. Modern TVs and PCs have had HDMI built in for years, so you should already be good to go. If you don’t have a spare HDMI cable lying around, you may have to buy one or repurpose one of your existing HDMI cables. Just don’t buy the expensive HDMI cables — even a cheap HDMI cable will work just as well as a more expensive one. Plug one end of the HDMI cable into the HDMI-out port on your PC and one end into the HDMI-In port on your TV. Switch your TV’s input to the appropriate HDMI port and you’ll see your PC’s desktop appear on your TV.  Your TV becomes just another external monitor. If you have your TV and PC far away from each other in different rooms, this won’t work. If you have a reasonably powerful laptop, you can just plug that into your TV — or you can unplug your desktop PC and hook it up next to your TV. Now you’ll just need an input device. You probably don’t want to sit directly in front of your TV with a wired keyboard and mouse! A wireless keyboard and wireless mouse can be convenient and may be ideal for some games. However, you’ll probably want a game controller like console players use. Better yet, get multiple game controllers so you can play local-multiplayer PC games with other people. The Xbox 360 controller is the ideal controller for PC gaming. Windows supports these controllers natively, and many PC games are designed specifically for these controllers. Note that Xbox One controllers aren’t yet supported on Windows because Microsoft hasn’t released drivers for them. Yes, you could use a third-party controller or go through the process of pairing a PlayStation controller with your PC using unofficial tools, but it’s better to get an Xbox 360 controller. Just plug one or more Xbox controllers into your PC’s USB ports and they’ll work without any setup required. While many PC games to support controllers, bear in mind that some games require a keyboard and mouse. A TV-Optimized Interface Use Steam’s Big Picture interface to more easily browse and launch games. This interface was designed for using on a television with controllers and even has an integrated web browser you can use with your controller. It will be used on the Valve’s Steam Machine consoles as the default TV interface. You can use a mouse with it too, of course. There’s also nothing stopping you from just using your Windows desktop with a mouse and keyboard — aside from how inconvenient it will be. To launch Big Picture Mode, open Steam and click the Big Picture button at the top-right corner of your screen. You can also press the glowing Xbox logo button in the middle of an Xbox 360 Controller to launch the Big Picture interface if Steam is open. Another Option: In-Home Streaming If you want to leave your PC in one room of your home and play PC games on a TV in a different room, you can consider using local streaming to stream games over your home network from your gaming PC to your television. Bear in mind that the game won’t be as smooth and responsive as it would if you were sitting in front of your PC. You’ll also need a modern router with fast wireless network speeds to keep up with the game streaming. Steam’s built-in In-Home Streaming feature is now available to everyone. You could plug a laptop with less-powerful graphics hardware into your TV and use it to stream games from your powerful desktop gaming rig. You could also use an older desktop PC you have lying around. To stream a game, log into Steam on your gaming PC and log into Steam with the same account on another computer on your home network. You’ll be able to view the library of installed games on your other PC and start streaming them. NVIDIA also has their own GameStream solution that allows you to stream games from a PC with powerful NVIDIA graphics hardware. However, you’ll need an NVIDIA Shield handheld gaming console to do this. At the moment, NVIDIA’s game streaming solution can only stream to the NVIDIA Shield. However, the NVIDIA Shield device can be connected to your TV so you can play that streaming game on your TV. Valve’s Steam Machines are supposed to bring PC gaming to the living room and they’ll do it using HDMI cables, a custom Steam controller, the Big Picture interface, and in-home streaming for compatibility with Windows games. You can do all of this yourself today — you’ll just need an Xbox 360 controller instead of the not-yet-released Steam controller.

• How to Tell If Your Computer is Overheating and What to Do About It

  - by Chris Hoffman

  Heat is a computer’s enemy. Computers are designed with heat dispersion and ventilation in mind so they don’t overheat. If too much heat builds up, your computer may become unstable or suddenly shut down. The CPU and graphics card produce much more heat when running demanding applications. If there’s a problem with your computer’s cooling system, an excess of heat could even physically damage its components. Is Your Computer Overheating? When using a typical computer in a typical way, you shouldn’t have to worry about overheating at all. However, if you’re encountering system instability issues like abrupt shut downs, blue screens, and freezes — especially while doing something demanding like playing PC games or encoding video — your computer may be overheating. This can happen for several reasons. Your computer’s case may be full of dust, a fan may have failed, something may be blocking your computer’s vents, or you may have a compact laptop that was never designed to run at maximum performance for hours on end. Monitoring Your Computer’s Temperature First, bear in mind that different CPUs and GPUs (graphics cards) have different optimal temperature ranges. Before getting too worried about a temperature, be sure to check your computer’s documentation — or its CPU or graphics card specifications — and ensure you know the temperature ranges your hardware can handle. You can monitor your computer’s temperatures in a variety of different ways. First, you may have a way to monitor temperature that is already built into your system. You can often view temperature values in your computer’s BIOS or UEFI settings screen. This allows you to quickly see your computer’s temperature if Windows freezes or blue screens on you — just boot the computer, enter the BIOS or UEFI screen, and check the temperatures displayed there. Note that not all BIOSes or UEFI screens will display this information, but it is very common. There are also programs that will display your computer’s temperature. Such programs just read the sensors inside your computer and show you the temperature value they report, so there are a wide variety of tools you can use for this, from the simple Speccy system information utility to an advanced tool like SpeedFan. HWMonitor also offer this feature, displaying a wide variety of sensor information. Be sure to look at your CPU and graphics card temperatures. You can also find other temperatures, such as the temperature of your hard drive, but these components will generally only overheat if it becomes extremely hot in the computer’s case. They shouldn’t generate too much heat on their own. If you think your computer may be overheating, don’t just glance as these sensors once and ignore them. Do something demanding with your computer, such as running a CPU burn-in test with Prime 95, playing a PC game, or running a graphical benchmark. Monitor the computer’s temperature while you do this, even checking a few hours later — does any component overheat after you push it hard for a while? Preventing Your Computer From Overheating If your computer is overheating, here are some things you can do about it: Dust Out Your Computer’s Case: Dust accumulates in desktop PC cases and even laptops over time, clogging fans and blocking air flow. This dust can cause ventilation problems, trapping heat and preventing your PC from cooling itself properly. Be sure to clean your computer’s case occasionally to prevent dust build-up. Unfortunately, it’s often more difficult to dust out overheating laptops. Ensure Proper Ventilation: Put the computer in a location where it can properly ventilate itself. If it’s a desktop, don’t push the case up against a wall so that the computer’s vents become blocked or leave it near a radiator or heating vent. If it’s a laptop, be careful to not block its air vents, particularly when doing something demanding. For example, putting a laptop down on a mattress, allowing it to sink in, and leaving it there can lead to overheating — especially if the laptop is doing something demanding and generating heat it can’t get rid of. Check if Fans Are Running: If you’re not sure why your computer started overheating, open its case and check that all the fans are running. It’s possible that a CPU, graphics card, or case fan failed or became unplugged, reducing air flow. Tune Up Heat Sinks: If your CPU is overheating, its heat sink may not be seated correctly or its thermal paste may be old. You may need to remove the heat sink and re-apply new thermal paste before reseating the heat sink properly. This tip applies more to tweakers, overclockers, and people who build their own PCs, especially if they may have made a mistake when originally applying the thermal paste. This is often much more difficult when it comes to laptops, which generally aren’t designed to be user-serviceable. That can lead to trouble if the laptop becomes filled with dust and needs to be cleaned out, especially if the laptop was never designed to be opened by users at all. Consult our guide to diagnosing and fixing an overheating laptop for help with cooling down a hot laptop. Overheating is a definite danger when overclocking your CPU or graphics card. Overclocking will cause your components to run hotter, and the additional heat will cause problems unless you can properly cool your components. If you’ve overclocked your hardware and it has started to overheat — well, throttle back the overclock! Image Credit: Vinni Malek on Flickr

• Automating video generation by adding an intro and a trailing video to the main video

  - by DevDewboy

  I have a video project I am trying to compile. Here is the overview: I have many videos which are 5 minute training sessions - Main video. The Intro Video will be a standard 5 second video that will have the Video title and Author. This will be concatenated to the main video. The Trailing Video will pretty much be a stock video that will be concatenated to the main video and have all the legaleze etc. The Intro Vid will smoothly fade into the main vid as well as when you get to end of the main video it will fade into the Trailing video nicely. The product is a new video with a Intro, Main & Trailer video all in one! The concept is really that simple. In fact I found an example of a person who has solved this and is doing exactly what I want. This solution is a Bash script that takes a config file that has the title, author, etc. and generates the Intro, the Ending and creates the resulting video with them concatenated. I am using Ubuntu 12.04 Server. I have been trying to take this as a sample and just running it with no luck because of incompatibility errors. I even attempted to convert it using .MP4 containers or .MKV. I am running into error after error or incompatibility issues. I went as far as changing out the ffmpeg binary using the 25 Oct 2013 version from http://ffmpeg.gusari.org/static/64bit/ which I like as I don't have to worry about rebuilding the binary. Almost successful but again I have some error which I cannot solve. I know part of the problem is the fact that video production, codecs, formats is a completely new field for me so I am attempting to work through this new territory. Perhaps an expert here has something similar that I can use as a guideline that uses MP4 or h.264 format. Or take the solution above from the URL and make it work with a more up-to-date version of ffmpeg. I will include the script and its parameter file and the output (abbreviated because of limitation) below. Basically as the script stands right now, when run I get the error [matroska,webm @ 0x27bbee0] Read error. This error is return from the 'reasembleVideo' routine from the first ffmpeg command. The following is the Parameter File: #!/bin/bash INPUTFILE="ssh_main.mp4" LOGO="logo.png" LOGOLENGTH="1" SPEAKER="Jason" TITLE="Basic SSH Video" DATE="October 28, 2013" SCENESTART="00:00:01" SCENEDURATION="00:00:09" OUTPUTFILE="ssh_basic_1" } The following is the script I am running. The ${OUTPUTFILE} being used is a small 2 minute video I create in screen-o-matic in MP4 format. Script on PasteBin (too long for Super User post)

• HR According to Batman

  - by D'Arcy Lussier

  Any idea who that guy is running alongside the Caped Crusader? That’s Nightwing, but you may know him as Robin…well, the first Robin anyway. There were actually like 5 Robin’s according to Wikipedia: Dick Grayson, the original, who’s parents were circus performers killed by a gangster. Jason Todd, who was caught trying to steal tires off of the Batmobile. Tim Drake, who saw Dick’s parents die and figured out who Batman and Robin were. and a few others that get into recent time travel/altered reality storylines. What does this have to do with HR? Well, it somewhat ties in with an article by Alex Papadimoulis from 2008. In the article he talks about the “Cravath System”. The Craveth system was developed by a law firm called Cravath, Swaine & Moore back in the 19th century. In a nutshell, they believed in hiring the best and brightest straight out of school. These aspiring lawyers would then begin a fight for survival in the firm, with the strong surviving. In what’s termed the “Up and Out” rule, employees needed to be promoted within 3 years or leave the company. They should achieve partner within 7 – 8 years and no later than 10 after initially coming on board (read all about the system on Wikipedia here). Back to Alex’s article, he quotes from a book published in 1947 about the lawfirm: Under the “Cravath system” of taking a substantial number of men annually and keeping a current constantly moving up in the office, and its philosophy of tenure, men are constantly leaving… it is often difficult to keep the best men long enough to determine whether they shall be made partners, for Cravath-trained men are always in demand, usually at premium salaries. And so we see a pattern forming here: 1. Hire a whole whack of smart college graduates 2. Put them to work 3. The ones that stick around should move up the ladder. The ones that don’t stick around served the company well and left to expound the quality of the Cravath firm. Those that didn’t fall into either of those categories were just let go. There’s some interesting undercurrents to these ideas. If you stick around, you better keep your feet moving! I was at a Microsoft shindig a few months back, and was talking to a Microsoft employee. He shared that at MS you have 5 years to achieve a “senior” position within the company. Once you hit that mark, you can stay there for the rest of your career (he told about a guy who’s a “senior” developer and has been for the last 20+ years working on audio drivers for Windows), but you *must* hit that mark within the timeframe. What we see with Microsoft is Cravath’s system in action, whether intentional or not: bring in smart young people and see which ones stick. You need to give people something to work towards. Saying “You must reach this level or else!” is one way to look at it. The other way is to see achieving a higher rank in the organization as something for ambitious employees to reach towards. It’s important for an organization to always have the next generation of executives waiting in the wings, and unless you’re encouraging that early on you may find yourself in a position of needing to fill positions that nobody has been working towards. Now, you might suggest that this isn’t that big of a deal because you could just hire someone from outside the organization, but the Cravath system holds to the tenet of promoting internally; develop your own talent, since your business is the best place for the future leadership to learn teh business from. It’s OK for people to quit. Alex’s article really drives this point home, but its worth noting here also: its OK for your people to quit. In fact its inevitable…and more inevitable that it’ll be good people that leave. Some will stay and work towards the internal awards of promotion, but a number will get experience, serve the organization well, and then move on to something else. This should be expected and treated as a natural business occurrence. The idea of an alumni of an organization begins to come into play here: “That guy used to work for <insert company here>”. There’s a benefit in that: those best and brightest will be drawn to your organization and your reputation will permeate your market through former staff that are sought after because of how well you nurtured them. The Batman Hook All of this brings us back to Batman and his HR practice: when Dick decided he’d had enough of the Robin schtick, he quit and became his own…but he was always associated with Batman and people understood where his training had come from. To the Dark Knight’s credit, he continued training partners under the Robin brand. Luckily he didn’t have to worry about firing any of them (the ship sort of sails when you reveal a secret identity), although there was that unfortunate “quitting” of the second Robin when the Joker blew him up…but regardless, we see the Cravath system at work: bring in talent, expect great things, and be ok with whatever they decide for their careers. It’s an interesting way to approach HR, and luckily for us our business isn’t as dangerous or over-the-top as the caped crusader’s.

• In the Mobile and Tablet World, How Much is Too Much?

  - by andrewbrust

  The week of April 26th was a huge one in the world of mobile and tablet devices,  There were so many individual developments, announcements and solidifications of strategy, it’s almost impossible to believe they occurred in the same month, let alone the same week. Things started with Apple and Gizmodo having a Law and Order moment over the latter’s procurement of what appears to be the former’s 4th gen iPhone prototype.  We found out on the 26th that Gizmodo blogger Jason Chen’s apartment was raided by police and, honestly, that was a bit much. But Apple didn’t stop there.  They also published Steve Job’s critique of Adobe Flash and his explanation of Cupertino’s embargo of Flash on iPhones, iPods and iPads.  If you ask me, this too, was a bit much. Apple finished up the week by releasing the 3G version of its iPad product to the US market. I like (iLike?) my WiFi iPad.  The idea of getting a version of it that required a second 3G service monthly subscription, is, well, a bit  much. Microsoft was in the news too.  It killed a project it hadn’t even acknowledged the existence of: the Courier tablet.  That’s a bit much too.  If a tree falls in the woods, and Microsoft says they can’t hear it anyway, could they really have chopped it down? Maybe Microsoft Research should have licensed some of Courier’s technology from other parts of Microsoft.  Then maybe they could have kept the product alive.  Ask HTC: they’re going to be licensing technology from Microsoft because Redmond insists that Google’s Android operating system infringes on certain of their patents.  And since HTC now builds a number of handsets on Android, instead of being beholden, as they once were, to Windows Mobile, that means they can keep making their products.  Why does HTC have to pay the royalties, and not Google?  Maybe Microsoft decided that going after GOOG would have been a bit much, even for them. The agreement came not a moment to soon: HTC released their “Droid Incredible” (that name’s a bit much), an Android 2.1 handset with amazing hardware and HTC’s own Sense UI, on April 30th (this past Friday). This phone is very well-reviewed.  Maybe that’s why Google basically decided to beg off introducing a version of its Nexus One phone (also manufactured by HTC) on the Verizon Wireless network.  Google backing down?  That’s incredible, if not also a bit much. And that brings us to HP.  Which this week announced its acquisition of Palm and its webOS mobile phone touch-oriented operating system.  HP also killed its own Slate initiative.  Apparently HP realized that Windows 7, even with a proprietary HP touch UI added on top, is no match for the iPad.  I’m guessing they think webOS might work a bit better,  And I’m wondering if HP even wants to use webOS for phone handsets, beyond the Pre and Pixi.  Using it just for slate devices would be a bit extreme, but maybe not too much. Honestly, this was not Microsoft’s best week.  It killed a project and a close partner did likewise.  Then that same partner bought a competing OS product, while another partner released their new product that uses yet another competing OS platform. What did Microsoft actually produce this past week? An update to its Windows Phone 7 developer tools that actually works with the version of Visual Studio 2010 released on April 12th, and the version of Silverlight released three days later. That took three weeks to get synced up, and that’s a bit much too. But at least it happened. Windows Phone 7 is Microsoft’s best hope for a comeback in the SmartPhone market and to offer a credible touch-based tablet device.  This week, two of Microsoft’s slate initiatives died, and its only mobile phone victory was around its competitor’s operating system.  I hope the new platform gets Redmond out of the PC ghetto and into the classes of device that get people really excited today.  If it can’t, that would be a bit much; probably too much.  And, as the signs at the Lonestar Cafe in NYC used to say, too much ain’t enough.

• IBM Keynote: (hardware,software)–>{IBM.java.patterns}

  - by Janice J. Heiss

  On Sunday evening, September 30, 2012, Jason McGee, IBM Distinguished Engineer and Chief Architect Cloud Computing, along with John Duimovich IBM Distinguished Engineer and Java CTO, gave an information- and idea-rich keynote that left Java developers with much to ponder.Their focus was on the challenges to make Java more efficient and productive given the hardware and software environments of 2012. “One idea that is very interesting is the idea of multi-tenancy,” said McGee, “and how we can move up the spectrum. In traditional systems, we ran applications on dedicated middleware, operating systems and hardware. A lot of customers still run that way. Now people introduce hardware virtualization and share the hardware. That is good but there is a lot more we can do. We can share middleware and the application itself.” McGee challenged developers to better enable the Java language to function in these higher density models. He spoke about the need to describe patterns that help us grasp the full environment that an application needs, whether it’s a web or full enterprise application. Developers need to understand the resources that an application interacts with in a way that is simple and straightforward. The task is to then automate that deployment so that the complexity of infrastructure can be by-passed and developers can live in a simpler world where the cloud can automatically configure the needed environment. McGee argued that the key, something IBM has been working on, is to use a simpler pattern that allows a cloud-based architecture to embrace the entire infrastructure required for an application and make it highly available, scalable and able to recover from failure. The cloud-based architecture would automate the complexity of setting up and managing the infrastructure. IBM has been trying to realize this vision for customers so they can describe their Java application environment simply and allow the cloud to automate the deployment and management of applications. “The point,” explained McGee, “is to package the executable used to describe applications, to drop it into a shared system and let that system provide some intelligence about how to deploy and manage those applications.”John Duimovich on Improvements in JavaMcGee then brought onstage IBM’s Distinguished Engineer and CTO for Java, John Duimovich, who showed the audience ways to deploy Java applications more efficiently.Duimovich explained that, “When you run lots of copies of Java in the cloud or any hypervisor virtualized system, there are a lot of duplications of code and jar files. IBM has a facility called ‘shared classes’ where we put shared code, read only artefacts in a cache that is sharable across hypervisors.” By putting JIT code in ahead of time, he explained that the application server will use 20% less memory and operate 30% faster.  He described another example of how the JVM allows for the maximum amount of sharing that manages the tenants and file sockets and memory use through throttling and control. Duimovich touched on the “thin is in” model and IBM’s Liberty Profile and lightweight runtime for the cloud, which allows for greater efficiency in interacting with the cloud.Duimovich discussed the confusion Java developers experience when, for example, the hypervisor tells them that that they have 8 and then 4 and then 16 cores. “Because hypervisors are virtualized, they can change based on resource needs across the hypervisor layer. You may have 10 instances of an operation system and you may need to reallocate memory, " explained Duimovich.  He showed how to resize LPARs, reallocate CPUs and migrate applications as needed. He explained how application servers can resize thread pools and better use resources based on information from the hypervisors.Java Challenges in Hardware and SoftwareMcGee ended the keynote with a summary of upcoming hardware and software challenges for the Java platform. He noted that one reason developers love Java is it allows them to ignore differences in hardware. He stated that the most important things happening in hardware were in network and storage – in developments such as the speed of SSD, the exploitation of high-speed, low-latency networking, and recent developments such as storage-class memory, and non-volatile main memory. “So we are challenged to maintain the benefits of Java and the abstraction it provides from hardware while still exploiting the new innovations in hardware,” said McGee.McGee discussed transactional messaging applications where developers send messages transactionally persist a message to storage, something traditionally done by backing messages on spinning disks, something mostly outdated. “Now,” he pointed out, “we would use SSD and store it in Flash and get 70,000 messages a second. If we stored it using a PCI express-based flash memory device, it is still Flash but put on a PCI express bus on a card closer to the CPU. This way I get 300,000 messages a second and 25% improvement in latency.” McGee’s central point was that hardware has a huge impact on the performance and scalability of applications. New technologies are enabling developers to build classes of Java applications previously unheard of. “We need to be able to balance these things in Java – we need to maintain the abstraction but also be able to exploit the evolution of hardware technology,” said McGee. According to McGee, IBM's current focus is on systems wherein hardware and software are shipped together in what are called Expert Integrated Systems – systems that are pre-optimized, and pre-integrated together. McGee closed IBM’s engaging and thought-provoking keynote by pointing out that the use of Java in complex applications is increasingly being augmented by a host of other languages with strong communities around them – JavaScript, JRuby, Scala, Python and so forth. Java developers now must understand the strengths and weaknesses of such newcomers as applications increasingly involve a complex interconnection of languages.

• 2011 The Year of Awesomesauce

  - by MOSSLover

  So I was talking to one of my friends, Cathy Dew, and I’m wondering how to start out this post.  What kind of title should I put?  Somehow we’re just randomly throwing things out and this title pops into my head the one you see above. I woke up today to the buzz of a text message.  I spent New Years laying around until 3 am watching Warehouse 13 Episodes and drinking champagne.  It was one of the best New Year’s I spent with my boyfriend and my cat.  I figured I would sleep in until Noon, but ended up waking up around 11:15 to that text message buzz.  I guess my DE, Rachel Appel, had texted me “Happy New Years”, because Rachel is that kind of person.  I immediately proceeded to check my email.  I noticed my live account had a hit.  The account I rarely ever use had an email.  I sort of had that sinking suspicion I was going to get Silverlight MVP right?  So I open the email and something out of the blue happens it says “blah blah blah SharePoint Server MVP blah blah…”.  I’m sitting here a little confused what?  Really?  Just about when you give up on something the unexplained happens.  I am grateful for what I have every day. So let me tell you a story.  I was a senior in high school and it was December 31st, 1999.  A couple days prior my grandmother was complaining she had a cold and her assisted living facility was not going to let her see a doctor.  She claimed to be very sick.  New Year’s Eve Day 1999 my grandmother was rushed to the hospital sometime very early in the morning.  My uncle, my little brother, and myself were sitting in the waiting room eagerly awaiting news.  The Sydney Opera House was playing in the background as New Years 2000 for Australia was ringing in.  They come out and they tell us my grandmother has pneumonia.  She is in the ICU in critical condition.  Eventually time passes in the day and my parents take my brother and I home.  So in the car we had a huge fight that ended in the worst new years of my life.  The next 30 days were the worst 30 days of my life.  I went to the hospital every single day to do my homework and watch my grandmother.  Each day was a challenge mentally and physically as my grandmother berated me in her demented state.  On the 30th day my grandmother ended up in critical condition in the ICU maxed out on painkillers.  At approximately 3 am I hear my parents telling me they don’t want to wake me up and that my grandmother had passed away.  I must have cried more collectively that day than any other day in my life.  Every New Years Even since I have cried thinking about who she was and what she represented.  She was human looking back she wasn’t anything great, but she was one of the positive lights in my life.  Her and my dad and my other grandmother constantly tried to make me feel great when my mother was telling me the opposite.  I’d like to think since 2000 the past 11 years have been the best 11 years of my life.  I got out of a bad situation by using the tools that I had in front of me.  Good grades and getting into a college so I could aspire to be the person that I wanted to be.  I had some great people along the way to help me out. So getting to the point I like to help people further there lives somehow in the best way I can possibly help out.  This New Years was one of the great years that helped me forget the past and focus on the present.  It makes me realize how far I’ve come since high school and even since college.  The one thing I’ve been grappling with over the years is how do you feel good about making money while helping others out.  I’d to think I try really hard to give back to my community.  I could not have done what I did without other people’s help.  I sent out an email prior to even announcing I got the award today.  I can’t say I did everything on my own.  It’s not possible.  I had the help of others every step of the way.  I’m not sure if this makes sense but the award can’t just be mine.  This award is really owned by each and everyone who helped me get here.  From my dad to my grandmother to Rachel Appel to Bob Hunt to Jason Gallicchio to Cathy Dew to Mark Rackley to Johnny Ennion to Lee Brandt to Jeff Julian to John Alexander to Lori Gowin and to many others.  Thank you guys for all the help and support.

• ROracle support for TimesTen In-Memory Database

  - by Sam Drake

  Today's guest post comes from Jason Feldhaus, a Consulting Member of Technical Staff in the TimesTen Database organization at Oracle.  He shares with us a sample session using ROracle with the TimesTen In-Memory database.  Beginning in version 1.1-4, ROracle includes support for the Oracle Times Ten In-Memory Database, version 11.2.2. TimesTen is a relational database providing very fast and high throughput through its memory-centric architecture.  TimesTen is designed for low latency, high-volume data, and event and transaction management. A TimesTen database resides entirely in memory, so no disk I/O is required for transactions and query operations. TimesTen is used in applications requiring very fast and predictable response time, such as real-time financial services trading applications and large web applications. TimesTen can be used as the database of record or as a relational cache database to Oracle Database. ROracle provides an interface between R and the database, providing the rich functionality of the R statistical programming environment using the SQL query language. ROracle uses the OCI libraries to handle database connections, providing much better performance than standard ODBC.The latest ROracle enhancements include: Support for Oracle TimesTen In-Memory Database Support for Date-Time using R's POSIXct/POSIXlt data types RAW, BLOB and BFILE data type support Option to specify number of rows per fetch operation Option to prefetch LOB data Break support using Ctrl-C Statement caching support Times Ten 11.2.2 contains enhanced support for analytics workloads and complex queries: Analytic functions: AVG, SUM, COUNT, MAX, MIN, DENSE_RANK, RANK, ROW_NUMBER, FIRST_VALUE and LAST_VALUE Analytic clauses: OVER PARTITION BY and OVER ORDER BY Multidimensional grouping operators: Grouping clauses: GROUP BY CUBE, GROUP BY ROLLUP, GROUP BY GROUPING SETS Grouping functions: GROUP, GROUPING_ID, GROUP_ID WITH clause, which allows repeated references to a named subquery block Aggregate expressions over DISTINCT expressions General expressions that return a character string in the source or a pattern within the LIKE predicate Ability to order nulls first or last in a sort result (NULLS FIRST or NULLS LAST in the ORDER BY clause) Note: Some functionality is only available with Oracle Exalytics, refer to the TimesTen product licensing document for details. Connecting to TimesTen is easy with ROracle. Simply install and load the ROracle package and load the driver. > install.packages("ROracle") > library(ROracle) Loading required package: DBI > drv <- dbDriver("Oracle") Once the ROracle package is installed, create a database connection object and connect to a TimesTen direct driver DSN as the OS user. > conn <- dbConnect(drv, username ="", password="", dbname = "localhost/SampleDb_1122:timesten_direct") You have the option to report the server type - Oracle or TimesTen? > print (paste ("Server type =", dbGetInfo (conn)$serverType)) [1] "Server type = TimesTen IMDB" To create tables in the database using R data frame objects, use the function dbWriteTable. In the following example we write the built-in iris data frame to TimesTen. The iris data set is a small example data set containing 150 rows and 5 columns. We include it here not to highlight performance, but so users can easily run this example in their R session. > dbWriteTable (conn, "IRIS", iris, overwrite=TRUE, ora.number=FALSE) [1] TRUE Verify that the newly created IRIS table is available in the database. To list the available tables and table columns in the database, use dbListTables and dbListFields, respectively. > dbListTables (conn) [1] "IRIS" > dbListFields (conn, "IRIS") [1] "SEPAL.LENGTH" "SEPAL.WIDTH" "PETAL.LENGTH" "PETAL.WIDTH" "SPECIES" To retrieve a summary of the data from the database we need to save the results to a local object. The following call saves the results of the query as a local R object, iris.summary. The ROracle function dbGetQuery is used to execute an arbitrary SQL statement against the database. When connected to TimesTen, the SQL statement is processed completely within main memory for the fastest response time. > iris.summary <- dbGetQuery(conn, 'SELECT SPECIES, AVG ("SEPAL.LENGTH") AS AVG_SLENGTH, AVG ("SEPAL.WIDTH") AS AVG_SWIDTH, AVG ("PETAL.LENGTH") AS AVG_PLENGTH, AVG ("PETAL.WIDTH") AS AVG_PWIDTH FROM IRIS GROUP BY ROLLUP (SPECIES)') > iris.summary SPECIES AVG_SLENGTH AVG_SWIDTH AVG_PLENGTH AVG_PWIDTH 1 setosa 5.006000 3.428000 1.462 0.246000 2 versicolor 5.936000 2.770000 4.260 1.326000 3 virginica 6.588000 2.974000 5.552 2.026000 4 <NA> 5.843333 3.057333 3.758 1.199333 Finally, disconnect from the TimesTen Database. > dbCommit (conn) [1] TRUE > dbDisconnect (conn) [1] TRUE We encourage you download Oracle software for evaluation from the Oracle Technology Network.

• How is the gimbal locked problem solved using accumulative matrix transformations

  - by Luke San Antonio

  I am reading the online "Learning Modern 3D Graphics Programming" book by Jason L. McKesson As of now, I am up to the gimbal lock problem and how to solve it using quaternions. However right here, at the Quaternions page. Part of the problem is that we are trying to store an orientation as a series of 3 accumulated axial rotations. Orientations are orientations, not rotations. And orientations are certainly not a series of rotations. So we need to treat the orientation of the ship as an orientation, as a specific quantity. I guess this is the first spot I start to get confused, the reason is because I don't see the dramatic difference between orientations and rotations. I also don't understand why an orientation cannot be represented by a series of rotations... Also: The first thought towards this end would be to keep the orientation as a matrix. When the time comes to modify the orientation, we simply apply a transformation to this matrix, storing the result as the new current orientation. This means that every yaw, pitch, and roll applied to the current orientation will be relative to that current orientation. Which is precisely what we need. If the user applies a positive yaw, you want that yaw to rotate them relative to where they are current pointing, not relative to some fixed coordinate system. The concept, I understand, however I don't understand how if accumulating matrix transformations is a solution to this problem, how the code given in the previous page isn't just that. Here's the code: void display() { glClearColor(0.0f, 0.0f, 0.0f, 0.0f); glClearDepth(1.0f); glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); glutil::MatrixStack currMatrix; currMatrix.Translate(glm::vec3(0.0f, 0.0f, -200.0f)); currMatrix.RotateX(g_angles.fAngleX); DrawGimbal(currMatrix, GIMBAL_X_AXIS, glm::vec4(0.4f, 0.4f, 1.0f, 1.0f)); currMatrix.RotateY(g_angles.fAngleY); DrawGimbal(currMatrix, GIMBAL_Y_AXIS, glm::vec4(0.0f, 1.0f, 0.0f, 1.0f)); currMatrix.RotateZ(g_angles.fAngleZ); DrawGimbal(currMatrix, GIMBAL_Z_AXIS, glm::vec4(1.0f, 0.3f, 0.3f, 1.0f)); glUseProgram(theProgram); currMatrix.Scale(3.0, 3.0, 3.0); currMatrix.RotateX(-90); //Set the base color for this object. glUniform4f(baseColorUnif, 1.0, 1.0, 1.0, 1.0); glUniformMatrix4fv(modelToCameraMatrixUnif, 1, GL_FALSE, glm::value_ptr(currMatrix.Top())); g_pObject->Render("tint"); glUseProgram(0); glutSwapBuffers(); } To my understanding, isn't what he is doing (modifying a matrix on a stack) considered accumulating matrices, since the author combined all the individual rotation transformations into one matrix which is being stored on the top of the stack. My understanding of a matrix is that they are used to take a point which is relative to an origin (let's say... the model), and make it relative to another origin (the camera). I'm pretty sure this is a safe definition, however I feel like there is something missing which is blocking me from understanding this gimbal lock problem. One thing that doesn't make sense to me is: If a matrix determines the difference relative between two "spaces," how come a rotation around the Y axis for, let's say, roll, doesn't put the point in "roll space" which can then be transformed once again in relation to this roll... In other words shouldn't any further transformations to this point be in relation to this new "roll space" and therefore not have the rotation be relative to the previous "model space" which is causing the gimbal lock. That's why gimbal lock occurs right? It's because we are rotating the object around set X, Y, and Z axes rather than rotating the object around it's own, relative axes. Or am I wrong? Since apparently this code I linked in isn't an accumulation of matrix transformations can you please give an example of a solution using this method. So in summary: What is the difference between a rotation and an orientation? Why is the code linked in not an example of accumulation of matrix transformations? What is the real, specific purpose of a matrix, if I had it wrong? How could a solution to the gimbal lock problem be implemented using accumulation of matrix transformations? Also, as a bonus: Why are the transformations after the rotation still relative to "model space?" Another bonus: Am I wrong in the assumption that after a transformation, further transformations will occur relative to the current? Also, if it wasn't implied, I am using OpenGL, GLSL, C++, and GLM, so examples and explanations in terms of these are greatly appreciated, if not necessary. The more the detail the better! Thanks in advance...

• Hey, Google: It’s Time to Add Multi-Window Multitasking To Android

  - by Chris Hoffman

  In 2012, Google’s Dianne Hackborn threatened to revoke CyanogenMod’s access to the Android Market if they moved forward with adding “Cornerstone” multitasking to their custom ROM. Samsung has since created their own multi-window multitasking feature. Dianne Hackborn said this “is something that needs to be done at the mainline platform level” so apps wouldn’t break. She was right — Android needs this as a standard feature and it’s time for Google to provide it. Doesn’t Android Have Multitasking? Android originally stood out from Apple’s iOS with its powerful multitasking. Applications can continue running in the background while you’re using another application. This makes Android powerful — you can even have BitTorrent clients downloading files in the background while using another app. Android still kept the design of a single app on screen at a time. This made a lot of sense when Android only ran on smartphones with small screens. Today, Android runs on everything from smaller smartphones all the way up to huge “phablets” like the Galaxy Note. Android has gone beyond phones and runs on 12-inch tablets, convertibles with keyboard docks, laptops, and even Android desktops. Android isn’t just a phone operating system. Samsung’s Multi-Window Isn’t Good Enough Samsung has tried to add value to Android by adding a multi-window feature. When you’re using a high-end phone like the Galaxy Note or Galaxy S, or a Galaxy tablet, you have the ability to run certain apps side-by-side with each other. There are big problems here. This only works on Samsung devices, and only on specific Samsung devices. To add support for this feature in a way that doesn’t break other apps, Samsung’s multi-window feature also only works with specific apps. You can’t just run any app in multi-window view, only the apps on the Multi Window bar Samsung provides. This prevents third-party apps from breaking, which is what Google was worried about with CyanogenMod’s Cornerstone feature. A feature that only works with a handful of apps on specific devices from a single manufacturer isn’t good enough. This feature needs to work on every Android device — or at least ones with suitably large screens and powerful enough internals. It needs to be an Android platform feature so application developers can ensure their apps will work properly with it on every device. Android developers shouldn’t have to add support for each manufacturer’s own multi-window feature if other manufacturers decide to copy Samsung. Floating Apps Are a Dirty Hack Floating apps also enable real multitasking. Remember that Android allows apps to run in the background while you’re using an app in the foreground. These apps can present interfaces that appear floating above the current app — think of it like using “always on top” to make a window always appear over every other app on a desktop operating system. You can install floating apps to browse the web, take notes, chat, and watch videos while using any app. Only apps specifically designed to run as floating apps will work, so you have to seek them out. Floating apps are also awkward to use because they float over the app you’re using, blocking parts of its interface. Microsoft added floating-window support to Skype for Android. You can have a video conversation and the other person’s face will always appear on your screen, even when you leave the Skype app. Microsoft is using more of Android’s multi-window multitasking power than Google is. Custom ROMs and Root-Only Tweaks Aren’t Acceptable Some custom ROMs are adding this feature to Android. Google threatened to revoke CyanogenMod’s access to the Android Market (now known as Google Play) if they added this feature because it could potentially break third-party apps. Today, other custom ROMs are working on split-screen multitasking. Samsung added their own version to their own devices. You can also get this feature by using a root-only Xposed Framework tweak known as XMultiWindow. If you have root access, you can get multi-window multitasking or any app on your device. This shouldn’t require rooting your device or installing a custom ROM. These third-party solutions often have awkward interfaces and bugs. We need an integrated, supported solution that works the same on every device. Why Multi-Window is Important Microsoft’s Windows 8.1 stands out among tablet operating systems for its powerful multitasking support, allowing you to view several apps side-by-side at the same time. Apple is also reported to be working on adding side-by-side apps to the iPad with iOS 8. On every competitor’s operating system, you’ll be able to view a web page while you write an email, watch a video while you browse the web, or chat with someone while you do anything else. But Android’s still remained frozen in time. Despite all Android’s underlying power — and despite the way Android allows apps to adapt to different screen sizes — Google is resisting adding this feature. Large-screen Android tablets like the Nexus 10 (remember that tablet Google hasn’t updated in over 18 months?) need this feature. So do huge phones, convertibles, laptops, and Android desktops. If tablets are the future of personal computing, we should be able to do more than one thing at a time on our tablets’ big screens. Microsoft, Samsung, and even Apple are realizing this — now it’s Google’s turn. Image Credit: Sergey Galyonkin on Flickr, Karlis Dambrans on Flickr
