I have never had an Android device before so pretty much everything is new to me at this point. I will be writing a bunch of articles regarding the basics of Android and more specifically the basics of Android 4.2 on a Google Nexus 7. In the process of working to root the Nexus 7 I needed to backup everything on the Nexus 7 device including everything that has been configured to date. I also have taken a bunch of screenshots that I wanted to make sure got backed up before I proceed with rooting it. Backing up the Google Nexus 7 is easy but there are a couple steps to make sure you get everything which I have outlined below.
Earlier tonight I was working on a project for a customer that wants to translate the Hebrew Interlinear Bible into English which obviously has been done many times before. This customer however has some translations that he wants to make for himself so I needed to find a Hebrew Interlinear Bible in text or PDF format. I was able to locate the Hebrew Interlinear Bible in PDF format however there was a separate PDF for each chapter in each book which numbers something like 930 different PDF’s. I was able to use the wget command described in detail below to download all of the PDF’s with a single command on my Windows 7 computer.
The rar command can be useful on Linux to not only compress a file but also split the file into multiple parts during the compression. This will make the files easier to transfer to other servers or easier for other people to download. First rar needs to be installed which can done on CentOS using the directions below. After that we describe how to easily compress and break a file into multiple chunks using one simple rar command.
There are a couple projects I work on that use LiteSpeed WebServer as the web server. LiteSpeed or LSWS comes out with releases on a fairly regular basis so it is important to upgrade often. This process is usually really easy as the server will send an email to the web server administrator email address notifying them of any new upgrades. Upon receiving the email you simply login to the LiteSpeed web administration interface, click on Version Manager, and then click the Upgrade link located to the right of the latest release that has typically already been automatically downloaded. A couple times I have run into an issue where some servers have downloaded the upgrade and others have not so I typically wait for all servers to download the upgrade before upgrading any of the servers. Tonight I decided to figure out how to jump start this automatic download process or force the download of new LiteSpeed versions so I wouldn’t have to wait for all of the servers to automatically download the latest version. Below I describe what the admin interface might look like while you are waiting for an upgrade to automatically download, how to force download the new LiteSpeed upgrade, and how to make sure that your server is configured to automatically download the latest software from LiteSpeed Technologies.
Someone at work asked me today if I could download a Youtube video for them so they could burn it to DVD for some project. I remembered being able to do this with a Firefox plugin but had forgotten which plugin I previously used. After a quick search I came up with the 1-Click Youtube Video Download Firefox plugin which made the task really easy. Follow the directions below to download Youtube videos.
