Install Android Application Directly Without it Being in the Market

Make sure that you check the ‘Unknown sources’ setting that will enable you to → Continue reading “Install Android Application Directly Without it Being in the Market”
Deleting Safari Cookies in iOS Simulator
If you are doing any kind of development that involves cookies and need to be able to delete them while testing iOS you will likely need to delete them as well.
The iOS simulator (Launched from Xcode by going to Xcode > Open Developer Tool > iOS Simulator) stores data for the simulator in the following directory on the host Mac OSX file system: /Users/<uid>/Library/Application Support/iPhone Simulator/
First, quit out of the iOS Simulator.
To find the cookies and delete → Continue reading “Deleting Safari Cookies in iOS Simulator”
Executing MySQL Queries and Commands from the Command Line to a Remote Server
Following are a couple of ways to execute SQL on a remote MySQL server via the shell.
Executing SQL directly from the command line:
$ mysql -u uid -p -h remote.host database -e ‘SQL query here;’
Executing SQL from a file on the local host on the remote server:
$ mysql -u uid -p -h remote.host database < file.sql
You can also connect to the remote mysql server and from the command line execute SQL from files on the local → Continue reading “Executing MySQL Queries and Commands from the Command Line to a Remote Server”
Executing Dynamically Generated SQL Queries from a Shell Script
Following is how to generate dynamic SQL in a shell script and then execute those queries.
Let’s say, for instance, that you have a list of tables that you want to flush regularly during development and don’t want to type in the SQL queries each time. Moreover, you just want to maintain a list of the table names and add and remove from it when necessary and have your script dynamically generate and execute the delete statements.
For the purposes → Continue reading “Executing Dynamically Generated SQL Queries from a Shell Script”
Send a Text Message To Your Cell Phone From E-mail
This might be old news but I came accross this today and wanted to make a note of it for myself for future reference.
All that you need to do is address the message to the phone number @ the service prodivers designated domain that they use to convert and forward the message content to your mobile device.
What I see interesting in this is being able to send txt messages from a system or service that encounters an error → Continue reading “Send a Text Message To Your Cell Phone From E-mail”

Do Not Use Symlinks in Jetty’s webapps Directory
I set up a development instance of Jetty on my local machine and have been happily coding, compiling and deploying via a shell script. The script copies the war from my user’s target directory to the jetty users’s home dir changes the permissions and then moves it to the /webapp dir creating a symlink to the name of the .war that is referenced in a number of config files.
This was working just fine until I did a merge with → Continue reading “Do Not Use Symlinks in Jetty’s webapps Directory”
Getting Markdown Viewer To Display HTML Formatted Markdown Content in Firefox Under Linux
I recently installed the Markdown Viewer 1.3 in Firefox 23.0 under Fedora Core 18. When I went to open a .md file in the browser it prompted me to download it.
To configure Firefox to display the markdown in the browser do the following:
Edit the ~/.mozilla/firefox/*default/mimeTypes.rdf file.
If there is not yet an existing RDF node for ‘text/plain’ add it, and add “md” as a file extension.
<RDF:Description RDF:about=”urn:mimetype:text/plain”
NC:value=”text/plain”
NC:fileExtensions=”md”
NC:description=”Text Document”>
<NC:handlerProp RDF:resource=”urn:mimetype:handler:text/plain”/>→ Continue reading “Getting Markdown Viewer To Display HTML Formatted Markdown Content in Firefox Under Linux”
