Learnings

Posted by Jessica Sun, 10 Jun 2007 17:11:00 GMT

I have a corporate job now—Java Development. It is all good. (^_^)

Having this corporate job means developing on Windows machine(s), which means for me brushing up on DOS commands. 

attrib: change file permissions
path: print your path variable
services.msc: open the services console
netstat: lists ports in use

I don’t think there is a need for this command in NT, XP or Vista, but I used to use it all of the time.

doskey: allows you use commands previously entered

Additionally, I now need to start using dos2unix & unix2dos.

Other things that I have learned recently:
  • Shift + Alt + B in InkScape—> traces bitmap (i.e. gets path/shape of some existing bitmap object)
  • I’m turning my dev box into a web server and am working on putting a stack together. Although I would love to try something cool and new like Nginx, I think I would be better off sticking with what I know (i.e. Apache). More about my first webserver later.
  • I’ve started a document about the Freelance Web Development Process with questions for the client that I found on the web, as well as links to design resources.
  • To find firefox shortcuts… enter the following line in the browser address bar: chrome://browser/locale/help/shortcuts.xhtml
  • Convert m4a to mp3 with these two lines…
faad foobar.m4a 
#converts m4a to wav
lame foobar.wav foobar.mp3  
#converts wav to mp3

More, more, more…

  • HTML space =  
  • Firebug
    1. Ctrl + Shift + C open web developer css
    2. Ctrl + Shift + L open command line
    3. Ctrl + Shift + K focus on search box
  • Cygwin & the Find command: In order to use the find command in cygwin, you must make sure that c:cygwin\bin; is before SystemRoot\system32
  • To deal with the firefox can’t center tables issue… add extra empty columns & have colspan across those columns
  • Jsp files are converted into servlets that are then compiled into .class files; I am guessing that other frameworks work in a similar fashion.
  • To my future selves, please remember that if you are getting a 500 error on a typo blog, make sure to check the file permissions for the log files at least thrice; they must be set to 755.
  • Screengrab is a firefox extension that does screen captures. Cool!!!
  • RAD7 requires that a target server be set for all projects.
  • The easiest way to search for a jar file by package name is…
    1. if the jar is a websphere or homegrown jar, navigate in cygwin to a sufficiently small directory where you think the jar might be and execute the following command: find . -name \. | xargs grep this.is.your.package
    2. if the jar is open source, enable javacious & google the package name.

One-liners

Posted by Jessica Sun, 07 Jan 2007 04:18:00 GMT

and Frequently used commands I can’t seem to remember the exact syntax of. Nothin’ fancy.

Linux
find . -name \*.* | xargs grep search_string

    navigate to folder you would like to search, enter this command with the search string you would like to find and this command lists all files containing that string
ps x -Ho pid,args
    lists all of the processes running
find / -name gcc
    finds all folders named gcc
sed '/$/,/' /home/Desktop/jessirae > /home/Desktop/jessirae2
    places a comma at the end of each line
paste -sd '\0' - /home/Desktop/jessirae2 > /home/Desktop/jessirae3
    The NEWLINE character of every line except the last line in each input file will be replaced with a separator

Ruby

"<a href=\"http://www.oldurl.com\">JessiRae.com</a>". gsub(/(http?:\/{2})\S+\.(\w+)(\S+)/,"http://www.jessirae.com/blog/")
    global substitution replaces all instances of some expression in a string with some other string or performs some function on that string
require 'open-uri' .... open(url) { |page| page_content = page.read() page_content }
    returns html from specified webpage
