Well, that was not the case when I last used WP-SuperCache in the Dreamhost VPS. I don’t know much inside details but Dreamhosters need to find an alternative when WordPress Cache is concerned. Mine didn’t crash but there are reports of such things happening like this one.

For my sites I found Hyper Cache does some justification in reducing the server load. There should be others but I haven’t tried them. Please comment your experience if you have experienced such problems.

Renaming a project in XCode is not so easy. There is no automatic procedure to do the renaming so I trying to do it manually … and it worked!

Suppose you want to rename the project named “TechX” to “TechX_New”.

1. Copy the “TechX” directory and name it “TechX_New”.

2. Rename the TechX.xcodeproj TechX.pch files inside the TechX_New directory to TechX_New.xcodeproj and TechX_New.pch.

3. Delete the build folder if you have any.

4. Open TechX_New.xcodeproj file in text editor, like TextMate or TextWrangler. [It is a folder containing 4 files - you can also right-click and do Show package contents, which will reveal the files]

5. Open project.pbxproj in text editor and replace all instances of the “TechX” with “TechX_New”.

6. Load the project file in XCode, do Build/Clean all targets

The application does its job but it is not a complete application. I am not so good in designing the interface so I might need to find somebody who can design the logo and stuffs.

With little more effort the application can be complete. I am however debating on whether I should spend $99 to get an account to publish it in the App Store. Nobody will be interested in buying it for sure. I am not sure how many people will really be interested in downloading it even if it is a free application.

I will be spending my free time in the future working on more projects. I hope one day I will be able to earn the amount I spend to get the developer account. That day I will have at least a few apps ready to hit the market.

FacePAD, also known as the Facebook Photo Album Downloader allows you to download your friends’ Facebook albums on a click of the mouse.

Requirements:

1. Firefox browser on any OS platforms (Windows, Mac OS, Linux)

2. A Facebook account with at least a friend with photo album … Actually, there is no no. 2 requirement.

All you need to do is download FacePAD Addon and install on the Firefox browser. Restart the browser and you are good to go photo hunting.

Navigate to your friend’s album and right-click on the album you are interested on. You will get a menu with “Download Album with FacePAD” on it. Click on it and everything is done automatically. The screenshot below is self-explanatory.

The photos will be saved on the default Firefox download folder.

The MacBook and MacBook Pro CirrusLogic sound chip are notorious for unsupportive sound drivers in Boot Camp 3 and 3.1. The internal microphone is not working in these machines and the volume of the loudspeakers is painfully low.

There is no official solution to the problem but Luca has proposed a work-around (that worked for me). His first solution is not working but the second one works like charm. It involves downloading the previous version of Boot Camp and extract the audio driver to update the current drivers.

Wordpress if one of the simplest content management system (cms) available. It is easy to install, deploy, and modify when compared to other GPL cms like Joomla, Drupal etc. With a huge user base, there is a vast pool of themes and plug-ins (mostly free) to choose from.

When I started using Wordpress in late 2006 the sites I designed didn’t have much traffic. I had the flexibility to use any plug-in or theme on the sites. But as the traffic increased the server couldn’t stand it. Then I realized that it was not only the site traffic that determines how much server resource is required to run the site.

The Wordpress core in itself is light-weight but when it is coupled with add-ins and custom themes it can be very resources hungry. The worst resources hog I experienced was a Related Post plug-in.

- Plug-ins can be heavy. Not all plugins are that bad but to be on a safe side; use less number of plug-ins
- Templates with a lot of features and that comes with plugins can also be very heavy.
- Keep homepage as light as possible with less javascript, images and scripts.
- Keep Wordpress updated and secured.
- Spams – fight them. Nobody needs them and they are heavy on server too. Use plugins like Akismet, Defensio, reCAPTCHA etc.
- Caching – When site traffic increases the database overload can occur. MySQL database limps trying to get the information needed to render the page. Best solution is to cache the pages so that database gets less load. There are various plug-ins like Wp-Cache, Wp-Super-Cache etc., to do the job.
- Revision – Latest version of Wordpress features ‘revision’. It is good to have history of every revision made on every post. But, it can be heavy on database too. There are plugins to limit the number of revision or delete revisions to make the database light-weight.

Real problem is the ‘del’ key. I still remember the time when I had to struggle in differentiating between the ‘backspace’ and ‘del’ keys. Now, I am longing for one.

It is not that hard to delete files in Mac:

– Drag to the trash can and empty.
– Hold the Control Key while clicking on the file for the sub-menu to delete (move to trash).

Mac OS is based on Linux so I hope the shell command might help.
[rm - remove a file use -r to recursively remove a directory]

But, I miss the luxury of ‘Ctrl+Del’.

As for the regular ‘forward delete’ key can be assigned to one of the regular keys in the keyboard by a free software, doublecommand. It however didn’t work for deleting files.

I was used to taking screenshots by ‘Print Screen’ key in PC but the key is missing in the Macbook I recently acquired. It can take screenshot for sure but in Mac OS the keys are: ⌘-Shift-2

Apart from taking the screenshot the command saves the image in the desktop too. If you don’t want to save it automatically you need to press one more key. The command ⌘-Shift-Control-2 copies the screen to clipboard.

The key 3 in place of 2 gives more flexibility in selecting what you want to include in the image.

In summary, for Mac OS:

⌘-Shift-2 – Captures screen and saves in a PNG file
⌘-Shift-Control-2 – Captures screen to clipboard
⌘-Shift-3 - Captures the selected screen area to a PNG file
⌘-Shift-Control-3 – Captures the selected screen area to clipboard

That was for Mac OS. But if you have installed Windows OS using Bootlogger then you would need different keys to do screen capturing. Screen capture keys are fn + F11 for built-in keyboards. For external keyboards, F14 does the job.

Summary for Windows OS:

F14 – Capture screen (External Mac Keyboard)
F14 + Option - Capture the selected area of screen (External Mac Keyboard)

fn + F11 – Capture screen (Built-in Keyboard)
fn + Option + F11 – Capture the selected area of screen (Built-in Keyboard)

In the Mac OS there is ‘Grab’ application, found in the Applications folder to take trimmed screenshot. Grab allows you to take a timed screenshot by selecting “Timed Screen” from the Capture menu. Snow Leopard takes this concept a bit further by allowing you to record video of your actions on screen in QuickTime Player.

Nice ad Microsoft!

Are you throwing away your Mac and buy a PC? You might not need to even if feel like testing it. A Mac version would always be around the corner.
