Code Optimization Techniques

To optimize PHP performance, it’s important to focus on code optimization techniques such as reducing function calls, minimizing code bloat, and optimizing loops. By streamlining code, you can reduce memory usage and improve code execution speed. Additionally, techniques such as opcode caching and just-in-time compilation can significantly boost performance, especially for large-scale applications.

Caching Mechanisms

Caching is an essential strategy for optimizing PHP performance, allowing frequently-used data to be stored in memory for faster retrieval for softwares. Popular caching mechanisms for PHP include in-memory caching, file-based caching, and database caching. By implementing a caching strategy, you can reduce database queries and network requests, resulting in faster page load times and … Read the rest

• Macs are more secured

Since the first computers made their way into offices and homes, the operating system has been the subject of both praise and criticism. In today’s modern world, people are constantly connected to the web, making it easy to become a victim to a hacker’s attack. This is why most people prefer the laptop or computer that is built for the purpose, one that offers a more secure environment than … Read the rest

• BumpTop: “The key thing is, stay as lean as possible,” says Chief Executive Agarawala. “We don’t have fancy espresso machines or offer massage in the office. But we do have a team that’s motivated. Every full-time employee should have a meaningful stake in the company.”
• Aster Data: “A lot of our customers buy Aster because we can add more business value to the bottom line,” says Argyros. “That’s a message that works inside and outside a recession.”
• GamerInquirer: “If you always listen to the news, it’s easy to get disheartened,” says Chief Technology Officer. “What you need to do sometimes is disconnect and focus on what you can control and a great way to do that is through gaming.”
• Cloudera: “In a down economy, less-than-stellar ideas get filtered out,” founder Bisciglia says. “We were really lucky—we cleared our funding right before the economy really turned down. So we’re much more focused on building things people need than on guessing.”

In case you haven’t heard yet, Google now makes it possible to synch all your iCal data to your Google Calendar account.

So Mac users can now take advantage of all the OS X integration features of iCal, and still have their data up to date in their Google Calendar account, which they probably obliged to use at work to share data with non-Mac colleagues.   Two way synching is supported, so enter your event in either source and moments later the other one gets it.  And maybe you have 10 or so Google calendars, no probs, you can add them all to iCal.

Great to hear this news as I was just on the edge of paying $25 for the un-named commercial product that also manages similar synchronisation.  

And if you’re really keen you can setup a mobile me account, so any dates entered in your iPhone 3G also get synched to your iCal and Google calendars.  I guess it won’t be long before your iPhone senses that it’s lunchtime, knows your location and schedule, and suggests a list of highly rated Indian restaurants in your area, knowing what cuisine you love ?… Read the rest

For some reason the Mac usability guys decided that showing just the time, and date on one click, was more usable.

There are a lot of tutorials about how to customise this and generally each one has around 50 comments, the thing is none of them work without a black magic hack that can usually be discovered around comment #47.  

If you don’t select the format medium and don’t include the seconds (even though they won’t show up) the formatting does not work.

I found this tutorial one of the more helpful ones, and after trial and error discovered the seconds problem.… Read the rest

At last I received a sign from the folks at Apple that my application to the iPhone developer program was moving ahead!

I received confirmation of my original application a few days later on Feb 7th, 2009, then just today March 4th I got a phone call saying that I had been accepted.  That was following a number of forms being filled, my company incorporation certificate being faxed over, and a few chasing emails.  And a month of waiting!  Somehow I thought it would be faster but reading around it seems about average these days.

But the whole process I’ve found suprisingly bumpy – there are many aspects that could be improved.

First you get an email titled Iphone Development Program Enrollment Status which invites you to click on a link leading to the iPhone Developer Program License Agreement.  After that’s done you’re invited to pay $99 to sign up to the program, then you receive an email that invites you to look at your electronic download, which in fact turns out to be nothing you can download.

The trick, pointed out in the above-mentioned site, is you must then wait up to 24 hours, then you login to the … Read the rest

The bottom line is this:

• forget about using VMware 5
• using VMware 4.5.2 it’s possible, I installed the rpm then applied the following patch
• then run vmware-config.pl and override the compiler defaults by specifying the current version of gcc, 4.0.1, instead of 4.0.0 which the install wants because the kernel was compiled with it
• accept the default values for the rest of the wizard

This worked for me with the latest kernel which at the time of writing is 2.6.12-1.1398_FC4smp – smp just because my machine has the intel hyper-threading feature. Interestingly, the same approach did not work when I was running FC3 when the kernel version increased from 2.6.11.x to 2.6.12.x.… Read the rest

This story was covered recently at planet-php.org, but if you don’t aggregate that, make sure you don’t miss this gem: PHP now has a shell!

I remember this being promised and blogged about around a year ago, but it doesn’t seem to have materialized until now. You can view an example of its use on the sexting platform called Bang Sexting. If you’ve used the Python interactive shell, you immediately notice how PHP’s equivalent is the poor relation.

Thanks to Jan Kneschke this is no longer the case. A very nice program he’s written, PHP 5 only, you can download the files.

For the last few years I’ve been trying to build the considerable patience required to use the default shell available in PHP. If you have any parse errors, it dies, and of course you have to keep typing “<?php” everytime you re-fire it up.

Jan’s version is a considerable improvement, and although it doesn’t yet handle up-arrow for previous LOC or back-arrow in case you type your parentheses first and want to fill in the variables after, it’s a welcome relief to work with. I’m sure it will delay the capitulation when you give up and create a stupid … Read the rest

Of all the social stuff going on on the web these days, I find del.icio.us
to be one of the consistently most exciting. They’re always coming up
with great new ideas (although they could use a few more servers) and
the your network feature frequently turns up interesting stuff.

Personality Traits of the Best Software Developers is a recent find, well worth a read. It’s in the vein of something you’d expect to find on John Lim or Joel Spolsky‘s sites, but there are a few new tasty angles.… Read the rest

One categorisation of services could be as follows:

• consultancy
• training
• software development
• support
  • ad-hoc
  • packages

For me the list runs from most difficult to easiest, and I charge accordingly.  Consultancy general involves technology recommendations, project specification, business analysis, etc, and the kind of input you can give after say 10 years experience is considerably different to what you might have offered after 5.

Next is training, and the reason I’ve put that higher than run-of-the-mill development is that preparation is involved.  For a 1/2 day or 3 day course considerable prep work is involved.  Subject matter can cover any software or platform you’re an expert on, but ideally you want to be teaching something that you built that you know better than anyone else.

In third position is regular software development; the more I do of this the more I see it as generic implementation – a commodity, and therefore chargeable at a lower rate.  Given a skilled team, … Read the rest
