• FrankenUPS Hack Turns a Server UPS into a Whole House UPS

  - by Jason Fitzpatrick

  This well documented build guide showcases the process of turning a rack-mounted UPS battery device intended for a server bank, into a super-charged whole-house UPS system with a massive 14 hours of backup juice. It’s a very ambitious build and, due to the work required in the main circuit breaker of your home, we highly recommend only those experienced with electrical work undertake the project. That said, it’s a really clever bit of recycling that yielded an impressive half-day worth of backup power. Hit up the link below for the detailed build log.

• Web-based CMS for mobile app

  - by JWood

  I'm just about to start developing a mobile app which needs to be fed from a CMS. I started designing the tables when I thought there must be something out there which could save me a load of time and let me concentrate on the mobile side of things. So, I'm looking for a CMS that will let me create hierarchical "pages" which will just be 4-5 database fields with a simple front-end to allow to edit and update them. I don't mind having to write some code to layout the database and forms etc, any saving on starting from scratch would be good. The only requirement is that I be able to access the data via some sort of web service, REST, JSON, XML, anything really... Can anyone suggest anything that might help? Thanks, J

• Adobe flash player not working with Amazon Prime

  - by Alex

  I have ubuntu 12.04 64bit using Google Chrome. I had chromium from the app center then today amazon prime video stopped working. It told me to update Flash. So I uninstalled chromium and installed Google Chrome. Didn't work. Then I downloaded flash for ubuntu via apt. That one gave me a "flash version isn't supported" message. The flash version was 11. Now I tried http://apt.ubuntu.com/p/flashplugin-installer It worked, but right in the middle of the video, it popped the error message again. Sorry we are unable to stream this video. This is likely because your Flash Player needs to be updated. So I don't know what happened.

• Inside The Kindle Paperwhite’s Display [Video]

  - by Jason Fitzpatrick

  By far the most praised feature of the new Amazon Kindle Paperwhite ebook reader is the new display; this video takes you behind the scenes with the design team and highlights what exactly makes the evenly lit display work so well. Accounting for the promotional nature of the video, it’s still fascinating to take a look at how they crafted the front plate of the display to yield such an even front-lit effect.

• A Rose by Any Other Name..

  - by Geoff N. Hiten

  It is always a good start when you can steal a title line from one of the best writers in the English language.  Let’s hope I can make the rest of this post live up to the opening.  One recurring problem with SQL server is moving databases to new servers.  Client applications use a variety of ways to resolve SQL Server names, some of which are not changed easily <cough SharePoint /cough>.  If you happen to be using default instances on both the source and target SQL Server, then the solution is pretty simple.  You create (or bug the network admin until she creates) two DNS “A” records. One points the old name to the new IP address.  The other creates a new alias for the old server, since the original system name is now redirected.  Note this will redirect ALL traffic from the old server to the new server, including RDP and file share connection attempts.    Figure 1 – Microsoft DNS MMC Snap-In   Figure 2 – DNS New Host Dialog Box Both records are necessary so you can still access the old server via an alternate name. Server Role IP Address Name Alias Source 10.97.230.60 SQL01 SQL01_Old Target 10.97.230.80 SQL02 SQL01 Table 1 – Alias List If you or somebody set up connections via IP address, you deserve to have to go to each app and fix it by hand.  That is the only way to fix that particular foul-up. If have to deal with Named Instances either as a source or a target, then it gets more complicated.  The standard fix is to use the SQL Server Configuration Manager (or one of its earlier incarnations) to create a SQL client alias to redirect the connection.  This can be a pain installing and configuring the app on multiple client servers.  The good news is that SQL Server Configuration Manager AND all of its earlier versions simply write a few registry keys.  Extracting the keys into a .reg file makes centralized automated deployment a snap. If the client is a 32-bit system, you have to extract the native key.  If it is a 64-bit, you have to extract the native key and the WoW (32 bit on 64 bit host) key. First, pick a development system to create the actual registry key.  If you do this repeatedly, you can simply edit an existing registry file.  Create the entry using the SQL Configuration Manager.  You must use a 64-bit system to create the WoW key.  The following example redirects from a named instance “SQL01\SQLUtiluty” to a default instance on “SQL02”.   Figure 3 – SQL Server Configuration Manager - Native Figure 3 shows the native key listing. Figure 4 – SQL Server Configuration Manager – WoW If you think you don’t need the WoW key because your app is 64 it, think again.  SQL Server Management Server is a 32-bit app, as are most SQL test utilities.  Always create both keys for 64-bit target systems. Now that the keys exist, we can extract them into a .reg file. Fire up REGEDIT and browse to the following location:  HKLM\Software\Microsoft\MSSQLServer\Client\ConnectTo.  You can also search the registry for the string value of one of the server names (old or new). Right click on the “ConnectTo” label and choose “Export”.  Save with an appropriate name and location.  The resulting file should look something like this: Figure 5 – SQL01_Alias.reg Repeat the process with the location: HKLM\Software\Wow6432Node\Microsoft\MSSQLServer\Client\ConnectTo Note that if you have multiple alias entries, ALL of the entries will be exported.  In that case, you can edit the file and remove the extra aliases. You can edit the files together into a single file.  Just leave a blank line between new keys like this: Figure 6 – SQL01_Alias_All.reg Of course if you have an automatic way to deploy, it makes sense to have an automatic way to Un-deploy.  To delete a registry key, simply edit the .reg file and replace the target with a “-“ sign like so. Figure 7 – SQL01_Alias_UNDO.reg Now we have the ability to move any database to any server without having to install or change any applications on any client server.  The whole process should be transparent to the applications, which makes planning and coordinating database moves a far simpler task.

• DIY Grid-It Clone Organizes Your Tech Gear in Style

  - by Jason Fitzpatrick

  If you’re looking for a customizable way to organize your cables and small electronics, this DIY Grid-It clone uses a series of elastic straps to hold everything in place. Grid-It is a commercial cable and device organizer that is, essentially, a stiff insert for your briefcase or bag that is wrapped in inter-woven elastic straps. You lift and slide the straps the secure your items in place creating, on the fly, customized organization for your cables and small devices. This DIY project recreations the Grid-It system using an old hard cover book as the foundation for the straps–it doubles the amount of usable space, provides a stiff cover, and (if you select a striking book) looks striking at the same time.

Also, where to install drivers for Ubuntu and all? This link https://help.ubuntu.com/community/MacBookPro has nothing for 9,1 so please help me. If I have to remove BootCamp and reinstall Windows manually because BootCamp doesn't allow resizing of partitions, that's fine. Please tell me how to install Precise on MBP 9,1 Thanks!

• Maximize Your Quadcopter’s Range with a Wi-Fi Repeater

  - by Jason Fitzpatrick

  The majority of commercial quadcopters use Wi-Fi for remote control and suffer from a fairly limited range. This simple hack uses an Wi-Fi router as an extender to radically expand the range of your copter. There’s no heavy modification or code tweaking required, all you need is a power source for the router and the ability to set it up as a repeater. The extra signal boost provided by the repeater extends the range from an average of 50 meters to over 250 meters. Check out the video above to see it in action. If you’re looking for a more dependable but more labor intensive way to extend the range of your copter, you can also retrofit it with a traditional radio-controlled remote.

• Google Now is One Step Closer to Becoming Active in Google Chrome

  - by Akemi Iwaya

  Many people have been eager to have Google Now working in their Chrome browsers and this week that dream got one step closer to reality. The first teasers that the new feature is becoming active have started to appear, so now is a good time to activate the switch for it and be ready for its arrival. You will need to be running the Dev Channel on your computer and enable the Google Now switch via Chrome Flags (chrome://flags/) if you have not already done so. The switch will be towards the bottom of the list. Once that is done restart your browser. After the browser has restarted you will see a notification window pop up as seen in the first screenshot above. Click Yes and a second small pop up message window will appear letting you know more about the freshly enabled feature. Unfortunately we were not able to catch a screenshot of the second message window before it disappeared.

• Google Storage for Developers…

  - by joelvarty

  I noticed this today and it seems to be a service that will compete with Amazon S3 and Microsoft’s Azure Blob storage. It’s only open to US developers for now, but I have one burning question: can we transfer directly from Google Storage to another Google service (like YouTube, Docs, etc) without incurring any transfer charges?  The even bigger question is whether all of the APIs will be updated to include this new service and to better amalgamate the existing app services with this one, since storage is so central to everything, it seems to beg the question. via Daring Fireball more later - joel
