Bookmark – jQuery UI Widget Collections

Knowing JavaScript and jQuery will get a developer only to a certain level of productivity before a plateau is reached where the next step is to become familiar with user interface widgets to make everything visually appealing and functional.

Thus far my primary experience has been using jqGrid but need to expand the number of available controls I’m comfortable implementing. I’m trying to locate which javascript widget libraries are the most popular and worth my time becoming familiar with. This is a list of the widget collections I intend to further review (in no particular order) :

Also worth noting are the following lists of jQuery Plugins and collections that came up in searching:

 

Bookmark – Chrome Keyboard Shortcuts

I’m old enough to remember when GUI became king and the idea of a computer user needing to know keyboard shortcuts to navigate a program was passé but it feels like things have come full circle and keyboard shortcuts feel more efficient. Navigating the GUI becomes mentally draining, looking for tabs, finding the right program on the task bar, etc are so much easier when I can just press a key combination to do what I want without having to search the screen.

With so much work being done within Chrome I found the following list of keyboard shortcuts to be exceptionally useful.

Dell R610 Memory Configuration Documentation

A situation came up at a client site where a Dell PowerEdge R610 / R710 server was being upgraded to a non-optimal memory configuration. The document Installing and upgrading DDR3 Memory was a short and concise reference for supported configurations.

The following two documents are Dell PowerEdge Technical Guides that also came in handy to when trying to decipher the supported memory configurations.

Removing an Existing Code Signing Certificate from a EXE

While trying to sign an EXE file with my code signing certificate SignTool kept failing with this error:

SignTool Error: SignedCode::Sign returned error: 0x800700C1
Either the file being signed or one of the DLL specified by /j switch is not a valid Win32 application.

The error was a result of the EXE being already signed.

Someone wrote a tool called delcert.exe which can easily remove existing code signatures. The tool is available for download from the XDA Developers Forum
