The first iPhone – Weekend must-read articles #21

iphone

Today it is five years since Apple’s very first iPhone went on sale. It was first unveiled in January 2007, but it took Apple six months to bring it to customers. We’ve collected a number of reviews and other articles about the iPhone, written just after it was released.

Pinterest has overtaken Tumblr in the United States

pinterestThe Web has been abuzz about Pinterest for a while now. There is, shall we say, a great interest in Pinterest. So much interest, it turns out, that Pinterest in all likelihood is now getting more traffic than Tumblr in the United States. And if it isn’t, it soon will.

How did we come to this conclusion? We hit as many data sources as we possibly could and made a highly educated guess, and just so you don’t think we are making this up, we’ll take you through the process.

AfricaAfrica, with its over 1 billion people, has reached a 13.5% Internet penetration rate, and there are plenty of big websites about the continent.

But where are those sites hosted? It would be safe to assume that there are big sites about Africa hosted outside the continent, but what would be the top 100 sites actually hosted in Africa?

That’s the question we set out to answer in our latest study. Read on to find out what we discovered.

Every sysadmin needs a little SysRq magic

sysreq key

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

Glance down at your keyboard. Look to the top right, somewhere above or around the “Page Up” and “Home” keys. If you’ve got a keyboard that follows long standing convention (at least if you’re using a PC), you’ll see a key that has the cryptic word “SysRq” on it somewhere, possibly as an alternate function. It likely shares a key with the words “Print Screen.” If you have a modern Lenovo laptop, you can stop searching for that key, however. In a bold departure from tradition, Thinkpads have recently been bereft of that oft neglected key.

What is this strange key and what does it mean anyway? “SysRQ” is short for the general term “system request”, however that doesn’t shed much light on its purpose. For that kind of information, we’ll need to step into our wayback machine and take a gander at computing history.

lynx

Do you use Lynx? If so, you’re one of a rather small minority that use the text-only web browser, which predates even the world wide web. Although it is still perfectly usable for most websites, the lack of graphics makes Lynx less than desirable for most users today.

But our curiosity got the better of us, and we wanted to find out how useful Lynx would be to browse some of today’s top websites. This is the sort of exercise that gives you a warm geeky feeling inside.

cloud storageThe cloud storage war is heating up. Dropbox is getting more and more competition, and now Google has joined the fray with Google Drive. We’re not going to compare features in this article, but rather test something we can actually measure. And since we here at Pingdom do site monitoring we have focused on how these services compare in terms of performance and reliability.

To make this survey even more interesting, we also added two other file hosting services: Microsoft’s SkyDrive and Box.com. They should give us some additional perspective.

To monitor reliability and performance, in this specific case we thought their homepages were less important than the actual file hosting they offer, so that is what we focused on. We uploaded the same identical file to the four services, a small PNG image, and made it publicly available so we could monitor it.

Not that long ago, social networking site Linkedin.com lost around 6.5 million hashed passwords. We talk about how this could have happened, what it means to you, and what you should think about in terms of your personal password policy.

Hadoop – Weekend must-read articles #20

Hadoop

Dealing with “big data” is a headache many companies and organizations are facing. That we have large amounts of data to process and store is perhaps not something new, but the sheer volume of data we now face are unprecedented. That’s where Apache Hadoop comes in.

jQuery

We’re big fans of the JavaScript library jQuery, and it appears we are far from alone. As of June this year it’s used by 54.7% of the top 10,000 websites in the world. That’s a massive endorsement by the world’s web developers. It’s also a significant step forward from two years ago, when 28% of the sites used jQuery.
