Web performance – Weekend must-read articles #29

web performance

This is our collection of must-read articles for the weekend.  There’s something about SPDY, caching, Google Octane, mobile web, Facebook and more.

Every week we bring you a collection of links to places on the web that we find particularly newsworthy, interesting, entertaining, and topical. We try to focus on some particular area or topic each week, but in general we will cover Internet, web development, networking, web performance, security, and other geeky topics.

visopsysVisopsys (VISual OPerating SYStem) is an alternative operating system for PC-compatible computers, developed almost exclusively by one person, Andy McLaughlin, since its inception in 1997.

Andy is a 30-something programmer from Canada, who, via Boston and San Jose ended up in London, UK, where he spends much of his spare time developing Visopsys,

We had the great fortune to catch up with Andy via email and ask him questions about Visopsys, why he started the project in the first place, and where is it going in the future.

The incredible story of the first PC, from 1965

P101 front

Almost 50 years ago, a small team at the Italian company Olivetti managed to do what no one had done before them; they created a computer small enough to fit on a desk, and could be used by regular people. It was the Programma 101, what many consider to be the world’s first personal computer.

The Facebook photo machine

facebookHere’s a number to make your jaw drop; Facebook users are posting 300 million new photos every day. This is an incredible amount of photos going into Facebook, the equivalent of an entire Flickr every three weeks.

Facebook stores and processes so many photos that they’ve had to build their very own software (Haystack) to be able to handle it.

300 million photos per day is impressive, but what is really mind-blowing is how quickly the amount of photos accumulate at that rate.

Temporary SMS restrictions in India

IndiaThe 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.

Commodore 64

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.

How that fruit company killed the netbook (charts!)

netbookRemember 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.
