Paypal has been around since 1998 (eBay bought it in 2002), which is a small eternity in internet time. By now it’s easily the most established online payment solution, so it should be in a great position to benefit from our general tendency to increasingly buy and pay for things online.

And something drastic happened about a year ago. Just look at how traffic to Paypal.com has been growing.

We computer geeks are a breed of our own, and as with any group of people with mutual references, we often make jokes and observations that are totally incomprehensible to outsiders.

So consider this post a litmus test. If you laugh at these jokes, then you are most definitely a computer geek.

If Facebook has its way (and it usually does), over the coming years a ton of websites and online services will become part of the open graph that Facebook is promoting, with Facebook firmly planted in the middle. The concept is very interesting, and the potential for this web of data from a wide variety of sources is enormous. You could say that Facebook will tie all our information, and the whole web, together.

There’s just one problem (two, if you count privacy): When the web becomes “interconnected” with Facebook, it also means that when Facebook breaks, the web breaks. In short, Facebook becomes a single point of failure for the web.

Five years ago, no one had heard about jQuery. It was just an idea in the back of Javascript guru John Resig’s head. Today, jQuery is by far the most popular Javascript library in the world and is used by over 28% of all websites on the internet.

jQuery is open source, web developers love it, it’s been embraced by a slew of big companies, and is close to becoming a de facto standard for website development. It doesn’t just have the support of the open source developer community behind it, it’s even received official support from Microsoft.

Perl has been around since 1987 and became an early darling of web developers. These days, however, you don’t hear much about Perl. Everyone seems to be talking about trendier languages like PHP, Python and Ruby, with Perl left in the back as a neglected, not-so-hip cousin.

That might lead you to think that Perl is dying, but as it turns out, it’s still used by plenty of websites out there, including some pretty big hitters.

Here are some of the more popular sites that use Perl extensively today.

Few have managed to make better use of the Open Source model than Mozilla, and we recently saw some very impressive numbers on how much of Mozilla’s work is done by volunteers versus its internal staff that we thought were worth sharing with you (emphasis in the quote below added by us).

Even as Mozilla’s internal staff has grown to 250, from 15 in 2005, an army of volunteers still contributes about 40% of the company’s work, which ranges from tweaks to the programming code to designing the Firefox logo.

Since we are a naturally curious bunch here at Pingdom, we had to ask ourselves how much the time that these volunteers contribute is actually worth in terms of money.

Are you a programmer? Want to do something for the environment and even make the world a better place? Then start optimizing your code!

It seems like today the solution to most software performance issues is to throw more hardware at the problem instead of making the software run faster on existing hardware. Doing more with less is a forgotten mantra, and Wirth’s Law continues to ring true:

Software is getting slower more rapidly than hardware becomes faster.

Today we enjoy websites that are full of content and services that let us take care of anything imaginable online (well, almost). But the ride to our “Web 2.0” world of today has taken quite a while. It has been about 14 years since the first web page with dynamic content was created. This is [...]
