`System Preferences` =&gt; `Keyboard` =&gt; increase `Key Repeat Rate`

If by &quot;cursor speed&quot;, you mean the repeat rate when holding down a key -  then have a look here:
http://hints.macworld.com/article.php?story=20090823193018149

To summarize, open up a Terminal window and type the following command:

    defaults write NSGlobalDomain KeyRepeat -int 0

More detail from the article:

&gt;Everybody knows that you can get a pretty fast keyboard repeat rate by changing a slider on the Keyboard tab of the Keyboard &amp; Mouse System Preferences panel. But you can make it even faster! In Terminal, run this command:
&gt;
&gt;defaults write NSGlobalDomain KeyRepeat -int 0
&gt;
&gt;Then log out and log in again. The fastest setting obtainable via System Preferences is 2 (lower numbers are faster), so you may also want to try a value of 1 if 0 seems too fast. You can always visit the Keyboard &amp; Mouse System Preferences panel to undo your changes. 
&gt;
&gt;You may find that a few applications don&#39;t handle extremely fast keyboard input very well, but most will do just fine with it. 

**Note: It requires a system restart**

Let&#39;s say I have a list `a` in Python whose entries conveniently map to a dictionary. Each even element represents the key to the dictionary, and the following odd element is the value

for example,

    a = [&#39;hello&#39;,&#39;world&#39;,&#39;1&#39;,&#39;2&#39;]

and I&#39;d like to convert it to a dictionary `b`, where 

    b[&#39;hello&#39;] = &#39;world&#39;
    b[&#39;1&#39;] = &#39;2&#39;

What is the syntactically cleanest way to accomplish this?

Without referring to a book, can anyone please provide a good explanation for `CRTP` with a code example?

How can I increase the cursor speed in terminal?
I have Mac OS X by the way.
It would also be interesting to know it for Linux.

I don&#39;t know what I should search for in Google (or what you like).

So I&#39;ve been trying to get dynamic libraries to work in my XCode project under Mac OS X. So far no joy.

I am able to load the dylib file, but when I call dlsym to get the function pointer, it returns 0 and dlerror says symbol not found.

So I am wondering if there is a simple way to list the symbols that are exported from a dylib file. Any ideas would be great.

I&#39;m new to Objective C. I have basic knowledge in C, including the concept of pointers. I have two basic questions:

 1. Can someone explain the difference between assign,copy, and retain with some analogy?
 2. How do you handle a function which returns pointer variable, and how do you perform messaging through a return pointer?

##The setup...
Trying to set up a clean Mac os X 10.6 install to develop python/django and I didn&#39;t remember running into this on 10.5.

After installing MySQL from the installer on `mysql-5.5.8-osx10.6-x86_64.dmg` I ran

    $ sudo pip install MySQL-python

and it seemed to go smoothly (output below)

    Successfully installed MySQL-python
    Cleaning up...

after this I tried:

    $ python -c &quot;import MySQLdb&quot;

and it crapped out on me with:

    Traceback (most recent call last):
      File &quot;&lt;string&gt;&quot;, line 1, in &lt;module&gt;
      File &quot;/Library/Python/2.6/site-packages/MySQLdb/__init__.py&quot;, line 19, in &lt;module&gt;

      Referenced from: /Library/Python/2.6/site-packages/_mysql.so
      Reason: image not found

##So on to my question...

What did I do wrong?/What else do I need to do?

Googling (and searching here) for this returns a lot of results getting this error message with Ruby not too many with Python tho.

How can I do an HTTP GET from a Un*x shell script on a stock OS X system? (installing third-party software is not an option, for this has to run on a lot of different systems which I don&#39;t have control on).

For example if I start the Mercurial server locally doing a *hg serve*:

    ... $ hg serve 

And then, from a Linux that has the *wget* command I do a wget:


    ... $  wget http://127.0.0.1:8000
    --2010-12-31 22:18:25--  http://127.0.0.1:8000/
    Connecting to 127.0.0.1:8000... connected.
    HTTP request sent, awaiting response... 200 Script output follows
    Length: unspecified [text/html]
    Saving to: `index.html

And on the terminal in which I launched the *&quot;hg serve&quot;* command, I can indeed see that an HTTP GET made its way:

    127.0.0.1 - - [30/Dec/2010 22:18:17] &quot;GET / HTTP/1.0&quot; 200 -

So on Linux one way to do an HTTP GET from a shell script is to use *wget* (if that command is installed of course).

What other ways are there to do the equivalent of a *wget*?  I&#39;m looking, in particular, for something that would work on stock OS X installs.



OS X: equivalent of Linux&#39;s wget

I install XAMPP server on MAC OS 10.6 it was working fine.
After a lot of days I checked it, but not working this time, localhost not opening this time.

after some R&amp;D I reinstall XAMPP server after uninstall

When I start the apache after reinstall it giving port 80 running a another webserver Then I restart system, then apache start ok, but same local host not working

Then I check Web Sharing in my System Preference then it was already Tuned Off ...

Please anybody tell me where I am wrong?

I want to copy all files in a directory except some files in a specific sub-directory.
I have noticed that `cp` command didn&#39;t have the `--exclude` option.
So, how can I achieve this?

How to use &#39;cp&#39; command to exclude a specific directory?

Some background info: I was looking to run a script on a Red Hat server to read some data from /dev/random and use the Perl unpack() command to convert it to a hex string for usage later on (benchmarking database operations).  I ran a few &quot;head -1&quot; on /dev/random and it seemed to be working out fine, but after calling it a few times, it would just kinda hang.  After a few minutes, it would finally output a small block of text, then finish.

I switched to /dev/urandom (I really didn&#39;t want to, its slower and I don&#39;t need that quality of randomness) and it worked fine for the first two or three calls, then it too began hang.
I was wondering if it was the &quot;head&quot; command that was bombing it, so I tried doing some simple I/O using Perl, and it too was hanging.
As a last ditch effort, I used the &quot;dd&quot; command to dump some info out of it directly to a file instead of to the terminal.  All I asked of it was 1mb of data, but it took 3 minutes to get ~400 bytes before I killed it.

I checked the process lists, CPU and memory were basically untouched.  What exactly could cause /dev/random to crap out like this and what can I do to prevent/fix it in the future?


*Edit:* Thanks for the help guys!  It seems that I had random and urandom mixed up.  I&#39;ve got the script up and running now.  Looks like I learned something new today. :)

/dev/random Extremely Slow?

On most terminals it is possible to colorize output using the `\033` ANSI escape sequence.

I&#39;m looking for a list of all supported colors and options (like bright and blinking).

As there are probably differences between the terminals supporting them, I&#39;m mainly interested in sequences supported by xterm-compatible terminals.

I&#39;ve created a standalone java application in which I&#39;m trying to change the directory using the &quot;cd&quot; command in Ubuntu 10.04 terminal. I&#39;ve used the following code.

    String[] command = new String[]{&quot;cd&quot;,path};
    Process child = Runtime.getRuntime().exec(command, null);

But the above code gives the following error 

    Exception in thread &quot;main&quot; java.io.IOException: Cannot run program &quot;cd&quot;: java.io.IOException: error=2, No such file or directory

Can anyone please tell me how to implement it?

What command, or collection of commands, can I use to return all file extensions in a directory (including sub-directories)?  

Right now, I&#39;m using different combinations of `ls` and `grep`, but I can&#39;t find any scalable solution.

I&#39;m wondering about changing the color of the cursor / caret in a `UITextField` (And `UITextView` if its the same answer) in iOS. I&#39;ve seen answers for OSX development, but nothing for iOS.

Is this even possible?

Change UITextField and UITextView Cursor / Caret Color

I just upgraded my Intellij IDEA to version 14, but I have the problem that my cursor in the editor window is acting &quot;different&quot;. It starts of in a sort of protected mode, which looks like the insert mode but it isn&#39;t, where I can&#39;t insert anything. After pressing some keys like &lt;kbd&gt;a&lt;/kbd&gt; it changes back to normal except that sometimes it goes in a selection mode and by that I mean if I hit &lt;kbd&gt;backspace&lt;/kbd&gt; instead of deleting the character as expected it just selects/highlights it. I find this behavior really annoying and I hope one of you can help me.

Additional Information:&lt;br/&gt;

&gt; &gt; Mac OS X 10.10 Yosemite&lt;br/&gt; Intellij 14.0&lt;br/&gt;

Please ask if i can provide any additional information which might be helpful.

I want to add `,00` at the end of the value of the textfield. 

It works well in iOS device, but in android cursor moves to starting point of the value in textfield. As a result, I&#39;m unable to add `,00`.
