How to do GPU programming on Macbook Air?
By GPU Programming I am assuming you mean high performance parallel calculations on the GPU without graphics (since you mention OpenCL and CUDA). If so this link may be helpful: https://anteru.net/2012/11/03/2009/. And that card definitely can't use CUDA.

Run terminal inside vim on a macbook?
Why don't you do things the other way around? You can use a terminal multiplexer such as Tmux and split a terminal window into two panes using C-b %. Inside the second pane you can run macvim inside a terminal with $ mvim -v You can navigate between the two panes with C-b o, (And do much more, but I'll leave it up to you to discover!) Doing things this way around is much more sane in my opinion, you get the full power of both the terminal and vim without having to hack around with Vim too much (Plus Tmux is very handy for many other uses). I hope doing things this way around is appealing enough for you!

Macbook Pro 15", backspace not working with VIM?
Most likely you are running vim in compatible mode. Create a file called ~/.vimrc and put the following lines in it. set nocompatible set backspace=indent,eol,start Setting the backspace option should change the backspace key to behave how you expect it to. However these should be set by the system vimrc on mac.

MacBook's Switchable Graphics to toggle by script
The best tool for this is Cody Krieger's gfxCardStatus, which not only allows forcing the setting from the menu bar, but also does a fine job of monitoring why your system has switched GPU modes.

detect start of scroll event in macbook
Use $(window).scroll instead of $('body').scroll http://flesler.com/jquery/scrollTo/ might be helpful Sample code. Though not relevant with your requirements but hoping it could help: $(document).ready(function () { var sidebar = $('#sidebar_content'); var top = sidebar.offset().top - parseFloat(sidebar.css('marginTop')); $(window).scroll(function (event) { var ypos = $(this).scrollTop(); if (ypos >= top) { sidebar.addClass('fixed'); } else { sidebar.removeClass('fixed'); } }); });

DataModelling or ER model building software for MacBook and MYSQL
You won't get automatic updates (I understand automatic updates as something that happens in the background without any action from you). MySQL Workbench however has a two-way sync that you can use to update your models at the same time you update your schema (from the model). You can select to do only one direction, but you have to trigger synchronization yourself.

How to take a snapshot of the entire system of Macbook Pro OS x 10.8 Mountain Lion
I dunno about "graceful" but Carbon Copy Cloner is definitely an easy solution for rolling back to a previous state. You can make an exact clone of your drive, then restore it back if something goes horribly wrong. I use CCC to make periodic backups of my Macs, as a sort of secondary backup to time-machine, which is easy to use but which I don't have total confidence in.

OpenCV- Webcam frame not working on macbook in Java
it's been a while since this question was asked, but since I had essentially the same problem, I will post a solution (found here) (it's a rather simple fix actually for a stupid problem): The camera needs time to initialize (not sure what the gory hardware details are, but there you go). To fix it I simply added Thread.sleep(1000), and it started working. A slightly better fix may be to wrap this in a loop which retries every 1000ms or so until the returned Mat is not empty. Hope someone benefits from this :-) EDIT: I should have read your code first. Silly me, apologies. The problem seemed very similar to mine, so I assumed it was the same.

How to produce kernel panic with power button on MacBook Pro
You don't specify which "MacBook Pro" model you're using. A built-in ethernet port isn't the only way to do two machine debugging anymore. You need to reboot after changing nvram, e.g. sudo nvram boot-args="debug=0x144 -v" sudo reboot Also, see the video and PDF from WWDC 2013 "What's New in Kext Development"

sync xcode proj between imac and macbook -- push fails
For anyone else who stumbles onto this: My question is really answered at Pushing git repository to Xcode. In summary, since iMac is on essentially all the time, and since git (appropriately) abhores pushing to a non-bare repository, the (one) solution to syncing is to set up a bare repository on the imac, and push and pull from this for both working copies.

Displaying Java BufferedImage on MacBook with Retina display does not work
It looks like the host peer component is expecting to render an image with one color model but encountering another. There are just too many ways for this to go wrong for a definitive answer, but everal things bear closer scrutiny: Verify that your BufferedImage has a compatible color model and space, for example. Consider scaling with AffineTransformOp, outlined here, as it can create a "destination image with the correct size and number of bands." While done() is executed on the event dispatch thread, verify hat the rest of your program is correctly synchronized.

My Apple MacBook hard drive crashed - provisioning profiles lost, is there a way I can still update my app?
Create a new certificate if needed then create a new set of provisioning profiles. Install the updated profiles and update your apps to use the new profiles. That's it. Not that big of deal other than spending 30 minutes redoing this stuff.

iOS: DequeTableViewCell..a little bit confused
It says clearly in documentation dequeueReusableCellWithIdentifier:forIndexPath: For performance reasons, a table view's data source should generally reuse UITableViewCell objects when it assigns cells to rows in its tableView:cellForRowAtIndexPath: method. A table view maintains a queue or list of UITableViewCell objects that the data source has marked for reuse. Call this method from your data source object when asked to provide a new cell for the table view. This method dequeues an existing cell if one is available or creates a new one based on the class or nib file you previously registered. . dequeueReusableCellWithIdentifier: Return Value : A UITableViewCell object with the associated identifier or nil if no such object exists in the reusable-cell

Confused about unistd_XX.h
So, the right way is using unistd.h for x64 and/or unistd_32.h for x86 and ia32. Those files are in the headers of your linux distro. but keep in mind that the path changes between distros (and even between kernels), so the best way to find out where exactly those files are is: uni_hack.h #if defined(CONFIG_X86) <---- replace with whatever you want, #ifdef CONFIG_IA32_EMULATION for example # include <asm/unistd_32.h> #endif - Kbuild file obj-m += kernel_module_example.o $(obj)/kernel_module_example.o: $(obj)/real_unistd.h $(obj)/real_unistd.h: $(src)/uni_hack.h FORCE cpp $(c_flags) -E -dM <$< >$@ <---- this will generate "real_unistd.h" in the directory of your kernel module, and it will contain the content of unistd_32.h Using the unistd.h for x64 is

8.3333333333e-4 is the same as 0.00083333. It equates to: 8.3333333333 * 10^-4 = 8.3333333333 times ( ten to the power of -4 ) = 8.3333333333 * 0.0001 = 0.00083333333 N.b. After rounding The e stands for exponent and the relevant Wikipedia article is http://en.wikipedia.org/wiki/Exponentiation

Confused about DBus
This sounds like you should write an isolated D-Bus service to act as a datastore, and communicate synchronously with it in your scripts to write and read values. You can use shelve to persist the values between service invocations. In the tutorial, the "Making method calls" section covers synchronous calls, and "Exporting objects" covers writing most of the D-Bus service.

I'm confused with C libraries
For the first question, glibc follows both standard C and POSIX, from About glibc The GNU C Library is primarily designed to be a portable and high performance C library. It follows all relevant standards including ISO C11 and POSIX.1-2008. It is also internationalized and has one of the most complete internationalization interfaces known. For the second question, yes, you can compile Linux using gcc. Even gcc itself can be compiled using gcc, it's called bootstrapping.

How to add this array to MySQL (very confused)
Let's say your array is $array: $length = count($array[0]); $rows = array(); for($i = 0; $i < $length; $i++) $rows[] = "(".array($array[0][$i].", ".$array[1][$i].", ".$array[2][$i].", ".$array[3][$i].")"; // Ugly language with no executemany function... So we build a INSERT INTO with many values by ourselves $sql = "INSERT INTO table (id, url, title, percent) VALUES " . implode(',', $rows); $stmt = $pdo->prepare ($sql); try { $stmt->execute($insert_values); } catch (PDOException $e){ echo $e->getMessage(); } $pdo->commit();

Confused about python imports
Module names are case-sensitive. Use: import Test.foo as foo (The as foo is so that you can call foo.bar in main.) You must also have ~/Development listed in PYTHONPATH. If using Unix and your login shell is bash, to add ~/Development to PYTHONPATH edit ~/.profile to include export PYTHONPATH=$PYTHONPATH:$HOME/Development Here are instructions for Windows. Further suggestions for debugging: Place import sys print(sys.path) import Test print(Test) import Test.foo at the top of test_foo.py. Please post the output.

A little confused about access count
Will the loginTimeMap slow the server if the size of the map exceed 10000? A HashMap has a time complexity of O(1). That is, it hashes, then goes straight to the value. It does not search for the value. That means that it's performance is not proportional to the amount of elements in the array, although with 10,000 entries it might be somewhat memory heavy!

Confused about the third normal form
If you want to strictly hold to the normalization and it's normal forms, you would have to start with 1NF. You might create separate tables for Make,Model,Owner and rename current one into Car. Then you can add foreign keys respectively. To uphold 2NF you can wonder to grab the year attribute from the VIN, which it contains as a model year number (does not necessarily have to be the same as the actual year of making). 3NF states that table columns should contain only columns that are fully dependent upon primary key, which would've been ok now.

Confused about the usage of Dropbox API
Nope. Your app account is a way where Dropbox can allow any client applications to access the Dropbox APIs. That said, when other users install your application, authorize/login to the app, they will make requests by using their own credentials, and your App API key. Your app API key is a way for Dropbox to know that which application is sending the request. But, the files, and other APIs will be executed with the user's credentials. So, the user's files will be uploaded to the user's account, and not to the account of your App. So, it's both, User specific + Application Specific.

Confused about unicode representations
The plain string has been encoded using UTF-8, one of a variety of ways to represent Unicode code points in bytes. UTF-8 is a multibyte encoding which has the often useful feature that it is a superset of ASCII - the same byte encodes any ASCII character in UTF-8 or in ASCII. In Python 2.x, use the encode method on a Unicode object to encode it, and decode or the unicode constructor to decode it: >>> u'u222b'.encode('utf8') 'xe2x88xab' >>> 'xe2x88xab'.decode('utf8') u'u222b' >>> unicode('xe2x88xab', 'utf8') u'u222b' print, when given a Unicode argument, implicitly encodes it. On my system: >>> sys.stdout.encoding 'UTF-8' See this answer for a longer discussion of print's behavior: Why does Python print unicode characters when the default encodin
