Free Online Electronic Parts Reference Guide!

Electrical What is a new site aimed towards making identifying/learning about electronic parts easier.  I took a quick look at their site and it seems like it’s a pretty good reference point.

For those of you just starting out with circuits or just getting back into it, check out and bookmark Electrical What for your future electronic circuit projects.

WHAT IS ELECTRICALWHAT?! Frustrated by the difficulty of searching schematic symbols through long lists with little information led to the creation of Elec

HowTweets – How to Find Great HOWTO/DIY Tweets on Twitter!

Well, it seems like yesterday that I launched TwitLi.st, a site that helps you find good people to follow on Twitter.   I was playing with PHP and Twitter API the other day (btw, I should have an in-depth tutorial post on that too soon), and made HowTweets.com.  (it’s basically the same code running on TwitLi.st but simpler)

Basically it’s a site where Twitter users can hashtag their tweets with #HWT, which HowTweets.com will collect and organize them according t

For people who want to customize their website for iPhone and other smartphone users, you might want to take a look at this great guide on how to get started.  Basically, it shows you how to blend the mobile CSS into your mobile website so it loads fast on the iPhone instead of loading the full website.

http://www.tripwiremagazine.com/wp-content/uploads/images/stories/Articles/jqtables/PicNet.jpg

jQuery is basically javascript extended, helping you get things done faster instead of you trying to code javascript from scratch.  I just noticed on Twitter TripWireMagazine.com has a great blog post on Top 25 jQuery plugins that can help you finish your web project faster.

PHP Hack – How to Run Background Processes!

Sometimes in web programming, you might need to run (or fork as they say) processes in the background so the web user doesn’t see all of the processing time plus it can potentially “freeze” the webpage on long data processing features of the site.

For that, you can always fork more processes.

The usual line I use is: exec ("/usr/bin/php proc.php >/dev/null 2<&1");

The problem I incurred with above line was that processes were forked except there was still some delay that the visitors saw.

To fix the issue so there’s absolutely no

Javascript Hack – How to Hide/Show Div Elements!

I’ve been doing a lot of PHP/Javascript/AJAX programming for a new Twitter site and I have to say, there’s a REALLY easy way to hide and show your entire div elements without doing much with Javascript but using the document.getElementById(‘whateveridhere’).removeAttribute(‘id’);.

Whatever you want to hide, (for example a questionnaire that you want to show on the top of the webpage if user clicks a button), you can easily do so by putting ALL your code under a <div> element with “display:none” tag.

So, here’s an exam

Mobile Browser Hack – Android, WebKit and Javascript/AJAX Trim() Functions!

Here’s a quick note on mobile browsers like Android, WebKit. Based on my testing, it seems that string trim() function is not supported.

I was trying to do something like:

if(mystring.trim()==”0″) etc…etc…

That won’t work in mobile browsers for some reason but you can do something like it using match instead: if(mystring.match(/0/)) etc…etc…

I don’t know exactly why trim() isn’t supported fully on mobile browsers but for those of you who have problems with your website that works on desktop browsers but

Twitter API DIY – How to Use Twitter API in PHP/JSON!

Lately, I have been building a new Twitter site and it has been literally taking ALL of my time (and thus less blog posts) but let me give you TWO great sites that can help you get a head-start on making your own Twitter site too.

First, you will need to learn that Twitter API basically relies on RESTful HTTP protocol.  Don’t worry about the funky name, it’s actually rather simple.  You send a message to Twitter API and then you get a message back.

Now, there’s two ways to receive data back, one of XML and the other is JSON.  JSON is supposedly better for
