The Indian government has issued a temporary restriction on the number of SMS messages that can be sent in a day (no more than 5 per subscriber). The latest information is that this restriction will last for two weeks, and affects all of India. If you live there, you are probably well aware of this by now.

This drastic measure was put in place by the Indian government to curb the spread of rumors and inflammatory material concerning recent violence in Assam, India. Many websites have also been blocked for the same reason. It is a complicated situation, but basically the Indian government is doing this in an attempt to limit civil unrest.

We’re Swedes, so it’s difficult for us to comment on this from the outside. What we are concerned about, however, is the technical side effect of this move.

Do you know how old the average Twitter or Facebook user is? Do you know what share of Reddit’s users are women? We could go on and on; when it comes to social network demographics, the questions are endless. This article is going to answer those questions for you, showing you the age and gender distribution on 24 of today’s most popular social networks and online communities.

Today we’re very excited to welcome another backend developer to the Pingdom team. Johan Sköld comes from Västerås, Sweden, where the Pingdom HQ is located. With his experience in performance-focused programming and “just get it done” attitude, he will be a great addition to the Pingdom team.

On August 1, the classic Commodore 64 computer turned 30 years old. That’s a long time in the world of technology, but the C64 has turned into the little computer that could, with lots of people still using it, websites dedicated to it, and more.

We wanted to pay our own respects to the Commodore 64 as well as all the dedicated users that have used the computer over the years. So we rounded up a number of photos of the C64.

The really cool thing is that these are all photos taken way back when it actually happened, when the Commodore 64 was new, in the 1980s.

Remember netbooks, those underpowered but very small and inexpensive laptops? If ever anything came and went in a whirlwind, that’s the example to we’d point to. Netbook sales are now a mere shadow of their former glory.

To some extent, netbooks were probably hampered by the wave of lightweight laptops that started appearing a couple of years ago. They weren’t quite as small, but small enough, and much more powerful. What they weren’t, however, was cheap. In that way they could not supersede the netbook.

HTTP response headers are usually pretty dry reading, but once in a blue moon you do stumble upon something that makes you smile. Here are some of our favorites.

Facebook is still growing and is getting close to enrolling that magic 1 billionth user. According to data we gathered from Socialbakers, Facebook has added 180 million new users in the past year. But where are those users coming from?

In this article we’ll look into just that. The population of Facebook is changing, growing in new places. For example, it turns out that in the past year, 30% of all new Facebook users have come from just two countries.

Broken Arrow, Oklahoma, population over 100,000, has a Facebook Page, currently with just over 1,300 likes. But that doesn’t make the city special with Facebook now close to 1 billion users.

But Broken Arrow is, in fact, very special because it appears to have taken the fascination for Facebook a step further than most other cities. How, you ask?

This is a post by guest blogger Wesley David. You can find more information about Wesley at the end of the article.

I have in two articles introduced you to SysRq and shared with you various ways it can be used. Now, in the last part of the series, I turn to troubleshooting SysRq with topics including what do you do if you don’t have a SysRq key, and limiting the capabilities of SysRq.

Automattic’s WordPress.com blog hosting platform just keeps growing. Traffic is up 25% compared to a year ago, and 79% compared to the year before that. It hosts around half of all WordPress sites in the world (of which there are currently 54.7 million)

It’s easy to forget how it started, as a small service by the people behind the open source WordPress blog software. Here is Matt Mullenweg’s short announcement from back in November of 2005, when WordPress.com was opened up for everyone:

Going back to the future would be nice, following in Marty McFly’s footsteps, but for now we’ll settle for just going back to the past. We have dug up 10 awesome vintage ads published in Byte Magazine from 1977 to 1984. It’s quite a mix of cool and quirky, funny and awesome.

When regular people post on Twitter, they normally use something like Twitter’s website or one of its official clients, or possibly a third-party Twitter client like Tweetbot or Echofon. Many large companies, however, have a more organized approach to social media and use special tools to manage their social presence.

According to the latest global web browser statistics, Safari accounts for 7.1% of desktop browsing traffic. That puts Safari in fourth place, after Chrome, IE, and Firefox.

But where around the world is Safari really popular? There must be places where it can claim much higher figures than 7.1%, surely. Of course there are, and, as it turns out, many of them are places you go if you don’t really want to pay taxes.

The heyday of the iPod was a huge deal for Apple. For many people, it was the first Apple product they owned, and those who fell in love with it often went on to buy other Apple products. This was sometimes referred to as the iPod halo effect, and gave Apple a mass-market reach it had never had before. Without the iPod, Apple wouldn’t have been anywhere near as successful in the past decade.

We often measure and analyze the web performance of sites here on the Royal Pingdom blog. Most recently we did a study of top ecommerce sites. Now, we’ll dig into the world’s top 100 blogs.

As you might expect, performance among these top 100 blogs is a rather mixed bag. There are sites that are small, fast, big, large, and everything in between. We have all the numbers and charts for you.

Apple has been dominating the tablet market ever since the company released the iPad, so calling the current situation a tablet war might be a bit overly dramatic. But things are heating up. The number of Android-based tablets is growing, and now even Google itself has joined the fray with the Nexus 7.

What is the current standing in this “tablet war,” and how does it differ across the world? Luckily, we can get an idea by using data from StatCounter. Their data is based on web usage (visitor stats from 3+ million websites), so it will represent the tablets actively used to surf the web.

Over the past few years, social networks have become a major communications channel for today’s brands and companies. That’s why it’s surprising to see that even now, in 2012, many of the world’s top brands have a relatively weak presence on both Twitter and Facebook.

Today it’s 31 years since Microsoft finalized the purchase of 86-DOS, also known as QDOS, or Quick and Dirty Operating System. This was the operating system that would be installed on the first IBM PC, introduced in August 1981.

The rest is history, as they say. If you would want to relive the good – ahem – old days of DOS before it was even called MS-DOS, here’s how you can.

There’s no doubt that Facebook is the dominant player on the social networking scene, but just how dominating is it? We know that there are many other social networks, including the well-known LinkedIn, Twitter, and others. How do they compare with Facebook in terms of traffic, that’s the question.

Last year we published a study of social networks with more than 1 million visitors per day. Then we could spot 29 websites that made the list. This time, it’s down to 26. It seems like Facebook keeps growing and many other sites find it harder to keep users.

Since its creation by John Resig in 2005, jQuery has become one of the most widely used JavaScript libraries on the planet. It’s used by more than half of the top 10,000 websites in the world, and keeps getting more popular every day.

One question web developers using jQuery are faced with is how they should host the jQuery file. Should they host it themselves, or should they use one of the freely available content delivery networks (CDNs)?
