QuickTip: Solved | Ubuntu 8.10 Firefox Flash Sound Issue

Posted by vikashazrati on Sunday, November 9, 2008

have a dict, which I need to pass key/values as keyword arguments.. For example..

d_args = {'kw1': 'value1', 'kw2': 'value2'}
example(**d_args)

This works fine, but if there are values in the d_args dict that are not accepted by the example function, it obviously dies.. Say, if the example function is defined as def example(kw2):

This is a problem since I don't control either the generation of the d_args, or the example function.. They both come from external modules, and example only accepts some of the keyword-arguments from the dict..

Ideally I would just do

Here's a mapping to make this easier:

nmap <silent> <Leader>cd :cd %:p:h<CR>

Note the use of :p first expand the % to a full path -- it takes care of the case where you're already in the correct directory. If that happens, %:h expands to an empty string and the :cd command throws an error. %:p:h is safe as it will never send an empty directory into the :cd command.

Note that 'autochdir' can be turned on to automatic

jQuery Snippets: replace




June 1st, 2007





Sometimes you just need to replace one element with another. Of course jQuery makes this easy! You might run this chain to replace one or more elements with a new one.

if you look at the thickbox code, this is what it takes to launch a
thickbox  tb_show("title","url","gallery"):

 $(domChunk).click(function(){
  var t = this.title || this.name || null;
  var a = this.href || this.alt;
  var g = this.rel || false;
  tb_show(t,a,g);
  this.blur();
  return false;
  });

for your question, i'd do it like this, adding this line:

// for is ok
tb_show("success,bravo",'url_to_success_message.html");

I just use Vimperator - and have actually hidden my tabbar altogether via the userchrome (Vimperator shows me how many tabs exist and where I am within them), and use Vimperators buffer list, gt, gT commands, as well as firefox's alt+number, ctrl+pageup and down hotkeys. All of these are more than enough to rapidly navigate tabs.

I'd have to agree that this is a pointless extension.

Flash video (flv)

ffmpeg is the best choice for making flash video sites (.flv files). The syntax is simple:

ffmpeg -i inputfile.avi flashfile.flv

A parameter you likely want is -ab, audio bitrate. The default is 64, which may be fine for home videos, but is is too poor if you want to promote your local talented singer in a music video. Example:

ffmpeg -i musicvideo.mpg -ab 256 Som_du_visnar2.flv

Also note that .flv files do not support a samlerate of 48000, but it will convert using the original file's rate anyway and fault on exit. Flash video can have a sample rate of 44100, 22050 and 11025. Set the audio sampling frequency with -ar freq (usually -ar 44100) if the original file has something other than the valid rates.

Options you may want to consider:

-ab (number)     # audio bitrate
-ar freq         # audio sampling frequency
-b video bitrate # defaults to 200, which is kind of low

You should also be aware of -sameq. This makes the video the same quality as the original, but tends to make flash video files twice the size as original mpeg's. This is bad when it comes to serving files, but it may be worth it if you really want your flash video to have high quality (and you have the bandwidth..).

(I dont know why? but i experienced FFMPEG doesnot convert all standard vodeos even in MPEG ,AVI format etc into FLV format. Do you know why? please email me at imtahir@gmail.com. Regards )

Update: Couple of things I've noticed to watch out for:

1. When completing URLs to open, the order of the entries in the list seems to be pretty random, instead of how Firefox usually does it (most used entries listed first). This can be a bit annoying.
2. The new modes do block out the GMail and Google Reader key shortcuts from working. To use them, you first need to press I and then they will work normally (press Esc to go back to normal mode).

Correct Way to Send Out Group Emails

When you send out an email to a group of people, simply putting them all on the to field is bad form.  First, it exposes all the email addresses, so everyone can see everyone else’s emails.  Second, if someone accidentally hits “Reply All” instead of “Reply” their response can easily be sent to the entire group instead of just you.

A few years ago, I got an email from a friend who was studying at Yale.  It was a yearly update about what was going on in his life.  He put everyone he knew in the To: field.  This included old classmates, current professors, relatives, etc.

One of his friends got the message and decided to respond with an update of all the stuff going on in her life.  She accidentally hit the “Reply All” button and sent a bunch of personal details to a list of mostly complete strangers.

There was another case awhile back where a real estate company sent out a message to a bunch of people looking for apartments in New York.  Everyone was listed in the To field which provided a very handy list that any recipient could quickly sell to a competitive real estate company.

There is a simple way to prevent this.  Simply put yourself in the To field and everyone else in the BCC field.  That way both “Reply” and “Reply All” will only come back to you and recipients can’t see each other’s email addresses.

tail(1) - Linux man page

Name

Synopsis

Description

Print the last 10 lines of each FILE to standard output. With more than one FILE, precede each with a header giving the file name. With no FILE, or when
FILE is -, read standard input.

Mandatory arguments to long options are mandatory for short options too.

--retry

keep trying to open a file even if it is inaccessible when tail starts or if it becomes inaccessible later; useful when following by name, i.e., with
--follow=name

-c, --bytes=N

output the last N bytes

-f, --follow[={name|descriptor}]

output appended data as the file grows; -f, --follow, and --follow=descriptor are equivalent

-F

same as --follow=name --retry

-n, --lines=N

output the last N lines, instead of the last 10

--max-unchanged-stats=N

with --follow=name, reopen a FILE which has not changed size after N (default 5) iterations to see if it has been unlinked or renamed (this
is the usual case of rotated log files)

--pid=PID

with -f, terminate after process ID, PID dies

-q, --quiet, --silent

never output headers giving file names

-s, --sleep-interval=S

with -f, sleep for approximately S seconds (default 1.0) between iterations.

-v, --verbose

always output headers giving file names

--help

display this help and exit

--version

output version information and exit

If the first character of N (the number of bytes or lines) is a '+', print beginning with the Nth item from the start of each file, otherwise, print the
last N items in the file. N may have a multiplier suffix: b 512, k 1024, m 1024*1024.
