I was navigating the web using Stumble and I saw an interesting post that enumerate 40 tips for the optimization of your PHP code so I decide to post this tips on mi site.

Just a few minutes ago Apple announce the creation of a SDK for developers this February so they can create third party applications for iPhone and iPod.

Here is the complete story:

Third Party Applications on the iPhone

Let me just say it: We want native third party applications on the iPhone, and we plan to have an SDK in developers’ hands in February. We are excited about creating a vibrant third party developer community around the iPhone and enabling hundreds of new applications for our users. With our revolutionary multi-touch interface, powerful hardware and advanced software architecture, we believe we have created the best mobile platform ever for developers.

It will take until February to release an SDK because we’re trying to do two diametrically opposed things at once—provide an advanced and open platform to developers while at the same time protect iPhone users from viruses, malware, privacy attacks, etc. This is no easy task. Some claim that viruses and malware are not a problem on mobile phones—this is simply not true. There have been serious viruses on other mobile phones already, including some that silently spread from phone to phone over the cell network. As our phones become more powerful, these malicious programs will become more dangerous. And since the iPhone is the most advanced phone ever, it will be a highly visible target.

Some companies are already taking action. Nokia, for example, is not allowing any applications to be loaded onto some of their newest phones unless they have a digital signature that can be traced back to a known developer. While this makes such a phone less than “totally open,” we believe it is a step in the right direction. We are working on an advanced system which will offer developers broad access to natively program the iPhone’s amazing software platform while at the same time protecting users from malicious programs.

We think a few months of patience now will be rewarded by many years of great third party applications running on safe and reliable iPhones.

P.S.: The SDK will also allow developers to create applications for iPod touch. [Oct 17, 2007]

Your easiest choice is one of those LCD cleaning solutions they sell in places where they sell computers. But they’re expensive, and why bother when you can make your own solution for next to nothing?

What you’ll need:

• Distilled water (available at your supermarket; tap water leaves streaks and minerals).
• White vinegar (you may substitute isopropyl alcohol; either way, make sure these substances are diluted before they come near your screen).
• A clean, soft cloth (never use any kind of paper product).
• A spray bottle.

Directions:

1. In the spray bottle, mix the distilled water and alcohol/vinegar, in a 1:1 ratio.
2. Turn off the LCD display.
3. Spray the mixture onto the cloth, never directly onto the screen.
4. Wipe gently – oh, so gently – from top to bottom. Do it horizontally, too, if you think that leaves a cleaner result.
5. Let the screen dry before turning it back on.

Hands Off!

Fingers leave dirt and oil smudges that must be cleaned off. Also, every time you touch the screen you risk doing damage to those tiny creatures inside that hold the colored flashlights. Keep your fingers to yourself.

Things you never and I say it again NEVER use with your LCD Monitor:

• Anything containing bleach or ammonia, such as Windex. That will react with the plastic and make the plastic screen become cloudy and discolored.
• Anything sharp, pointy or abrasive.

Past September in San Diego at the Demo Fall 2007 Show, the Company Fusion-io presents a a new alternative to your Hard Disk with better performance..

The ioDrive is a flash memory PCI express card with up to 6,360 Gb. of capacity and a bandwidth equivalent to 1,000 disk drives.

The ioDrive is unlike a traditional solid state disk (SSD) in that the controller and NAND memory chips are integrated on a single card which is plugged into an X86 server’s PCI Express bus and doesn’t use a serial-attached SCSI (SAS) or Fibre Channel interface.

Data is moved using direct memory access (DMA) and the card is said to have up to 160 separate and parallel I/O pipelines which aggregate to delivering over 100,000 4KB data transfers a second. Flynn says the device can transfer eight full length DVD movies at one every five seconds.

The ioDrive can be used as a tremendously fast disk or set up as swap space for a server’s RAM. Fusion-io says that ioDrives can be aggregated together in boxes which can then be integrated in a RAID system to provide greater capacity, performance and reliability.

Fusion-io says that the driver code has to be tuned to the operating system. It has released sustained data rate performance comparisons showing that the ioDrive’s 800MB/sec read I/O rating is more than 200 times faster than a Samsung 32GB SSD at 57MB/sec, and both a 146GB SAS disk and a 146GB 2Gbit/sec Fibre Channel disk each rated at 96MB/sec. The card’s sustained write I/O rate is 600MB/sec.

it will be delivered by the end of 2007 or in the first quarter of 2008. The first OS to be supported is Linux, with Windows server and then Windows client (Vista and XP) operating systems following in the first quarter on 2008.

The only inconvenient is going to be the price at the beginning as always happens with all the new stuff.

Capacities of 80, 160, 320 and 640GB are planned with pricing around $30/GB. A 160GB card would cost around $4,800. Flash prices are halving every twelve months or so, meaning the card could be $2,400 ($1,200) in 2009.
