CloudDiff Chrome Extension


CloudDiff - Compare versions of your Dropbox or pCloud text files in-browser or using your configured diff tool.

Updates

2018-02-01 update (version 1.0.2.25) - Rename to "CloudDiff" (formerly "DropboxDiff") with a new Chrome Web Store extension ID -- be sure to update to latest CloudDiff HelperpCloud support.  Switch from jsdifflib to CodeMirror for inline diff.


I've written CloudDiff, a Chrome extension which allows you to compare different versions of text files you have on Dropbox or pCloud.  It can perform the diff in-browser, or trigger a diff tool you have installed on your local machine already, which you must configure.
  1. On the Dropbox website, browse to the "Version history" page of any text file.
  2. On the pCloud website, browse to the "Revisions" page of any text file.
  3. A "Diff" column has been added where you can select which two versions to compare.
  4. To trigger your already-installed diff tool, click the "Diff" button.
    1. If a diff tool is not yet configured, the Options page opens where you can specify one. If you don't have one installed already, one option is KDiff3. The setting is accessible from Tools > Extensions > CloudDiff > Options.
    2. An additional executable must be installed, CloudDiff Helper, in order to trigger your diff tool.  Follow the instructions to install.
    3. If configured correctly, your diff tool should open.
    4. To perform the diff in-browser, click the "Inline" button.
This should run on Windows, Mac, and Linux.  Note that the combined file-size limit in any comparison is 4GB.  Please let me know if any issues come up.

Get CloudDiff.

Blame it on the Tron

I watched old school Tron the other night. So much awesome kitch in that movie, I couldn't stop grinning during the whole thing.

Some things I noticed, since last time I watched it, a few decades ago:

The "Watseka" street sign sounded really familiar. Lo and behold:


View Larger Map

I live within 10 miles of Flynn's! We'll have to pay homage some time. Here's the wider shot.

I don't think they used the same spot for Tron: Legacy, though.

I also don't remember this blatant Easter egg:

They even sampled the Pac-Man sound effects. I remember Pac-Man being such an incredible craze at the time (we sang the "Pac-Man Fever" song in school once, badly), but somehow I never caught it here.

The Messianic overtones of the movie were pretty interesting too — Flynn being the User/god, come to inhabit the world of programs in order to save them. I certainly didn't pick that up as an 8-year old. Then again, it's only these days that I spend any time wondering whether our reality is just a computer simulation.

Here's a bit of dialogue I liked quite a bit.  Flynn has just revealed to Tron that he is actually a User, and not just a program, like the rest of them.
Tron: "If you are a User, then everything you've done has been according to a plan, right?
Flynn: "You wish! You guys know what it's like; you just keep doing what it looks like you're supposed to be doing, no matter how crazy it seems."
Tron: "That's the way it is with programs, yes..."
Flynn: "I hate to disappoint you pal, but most of the time that's the way it is for Users, too."
Tron: "Stranger and stranger."
Wise words.

Facebook Dis

Have you ever been alone, minding your own business, and suddenly realize that someone has been following you, watching your every move, for the past two hours?

That's what it feels like when I'm visiting different websites and I suddenly see:


"[various friends] like this."

The scary thing is that the stalker metaphor is quite appropriate – Facebook really is stalking you, keeping track of wherever you go whenever you see one of these.

So I really liked a Chrome extension called Facebook Disconnect.  Unfortunately, it tends to break some sites (Scrabble, in particular).  So I extended the extension to allow whitelisting certain sites.

Presenting:  Facebook Dis.

If you really want to get fancy you can read the whitelist from a specific URL, say a website or public Dropbox file.  This lets you to configure several installations of Facebook Dis in a single place; all instances will stay up to date automatically the next time you open your browser or click "refresh" from the options page.

Thanks to Brian Kennish for the original Facebook Disconnect.

Fast Make for Vim

2014-05-18 update - This is now vim-make on GitHub.

I wasn't really satisfied with Vim's :make behavior so I wrote a script to do what I wanted.
  • Saves buffer first
  • If there are errors, show them in the quickfix window
  • Success is reported in the status bar
  • Saves some keystrokes, especially if mapped to F5
Here it is. You can put it in ~/.vim/plugin/Make.vim, or if you are using pathogen, ~/.vim/bundle/Make/plugin/Make.vim.

This is basically my first Vim plugin so please let me know if there are things I could improve.
"=============================================================================
" File: Make.vim
" Author: Victor Shih
" Last Change: 3/30/2011
" Version: 0.01
" WebPage: http://blog.vicshih.com/2011/03/fast-make-for-vim.html
" Description:
" Custom Make command:
" - if results are a single line, echo;
" - otherwise output to quickfix buffer
"
" Usage:
"    :Make [<target(s)>]
"
" Trigger via F5 by specifying:
"
"   if exists('g:make_loaded')
"     map <buffer> <F5> :Make<CR>
"     imap <buffer> <F5> <ESC>:Make<CR>
"   endif
"
" in any desired ftplugin scripts.
"
" g:make_loaded is set when this script is run
"
function! Make(args)
  " Close quickfix
  cclose

  " Compile arguments
  let l:args = strlen(a:args) ? ' ' . a:args : ''
  let l:title = expand('%') . ' - Make' . l:args

  " Force write
  silent write!

  " Move to current directory
  lcd %:p:h

  " Make
  let l:out = split(system('make' . l:args), "\n")
  let l:len = len(l:out)

  " Output to quickfix
  cgetexpr l:out
  let w:quickfix_title = l:title

  " If no output, just report success
  if l:len == 0
    redraw
    echo l:title . ' succeeded'
  " If output is a single line, echo it
  elseif l:len == 1
    cc 1
    redraw
    echo l:out[0]
  else
    execute 'copen' l:len + 1
    cc 1
  endif
endfunction

command! -nargs=? Make call Make("<args>")

let g:make_loaded = 1

Ruby Autoflush

Google seems to need help with this particular association, so here goes.

In Ruby, to flush currently buffered data just once, call flush on the handle in question:
STDOUT.flush
To "autoflush", or continuously flush output immediately, set the sync attribute:
STDOUT.sync = true
References: flush, sync

Keyboard Shortcuts for Facebook Photo Tagging

Finally got around to tagging some photos in Facebook. I probably would not have bothered, had gleeBox not made it a bit tolerable by providing some form of keyboard shortcuts for the process:
  • Created an "ESP vision" for the Page URL
    facebook.com/photo.php
    with the jQuery selector
    #photoactions>a[onclick],input[type="submit"]
    #photoactions>a:first-child,input[type="submit"]

  • Changed my "Shortcut to launch gleeBox" to ";"

This allows tagging to go as follows:
  • Navigate to a Facebook photo album

  • Press ;<ENTER> with left hand to enter tagging mode

  • Tag at will

  • Press ;<ENTER> again to leave tagging mode

  • Left-click photo to move to the next photo

With the target crosshairs, it's about as close to an FPS you can get.
