Down the memory lane with Digit

My tryst with the modern PCs started in the mid 90s when the internet was almost non existent in India. At the time, software and games were not easy to come by and magazines like Chip which have away trial versions and freeware in CDs along with their copies were quite sought after. Chip later became Digit in India but the freebies continued.

It was with this thought that I attended the Digit Squad Tech Day in Mumbai today and it was fun to see all the colourful assembled desktops, consoles and mobile phones placed around the venue and fellow Digit Squad members participating enthusiastically in the different contests. Felt quite nostalgic to soak in the geeky environment.

Didn’t sit around idle of course and instead captured a few videos of the front camera fall detection in action for the smartphones on display. You can catch the video here.

OnePlus and Oppo seem to be catching on quite soon and they flash a dialog on screen while Samsung seems to be partially retracting their module. The Redmi K20 pro is similar in terms of responsiveness to Oppo and OnePlus but it closes the camera app instead of showing any alert. The Asus Zenfone 6z provides an interesting experience where you can see the arc on screen as the module rotates to its resting position.

And here are a few more shots from the event


Well-crafted website hints

I remember the AJAX evolution and the RIA craze pretty fondly myself:

A JavaScript API called XMLHttpRequest came along, originally only supported in a handful of browsers. This let a web page make a request to another URL and do something with the data — quite a revolutionary concept at the time.

XMLHttpRequest didn’t get a lot of adoption until the idea got a better name: Ajax.Jesse James Garrett’s famous blog post was successful because it (1) let people know that this technique existed and (2) gave it a much easier-to-pronounce name.

Power efficiency of AlphaGo’s victory

So another decade maybe before it achieves power parity?

Lee Sedol used about 20 Watts of power to operate. By contrast, AlphaGo runs on a whopping 1920 CPUs and another 280 GPUs for an estimated power consumption of approximately 1 MW (200 W per CPU and 200 W per GPU). That’s 50,000 times as much power as the amount of power that Lee Sedol’s brain uses and the two are not quite evenly matched but it is close enough to use for comparison.

Updating iOS on an ancient iPad 2 from 4.3

Recently faced an issue when trying to update an old iPad 2 from its original 4.3 OS. Back in those days even OTAs were not supported and iTunes was the only way to update. Since Apple has switched off validation for iOS versions older than 9, the iPad was going into an “Error 9” unusable state and there seems to be a lot of frustrated users out there who seem to be trying to update to iOS 9 from 4.X.X and failing to do so.

Some Googling turned up a suggestion to update to the beta version of iOS 9, and voila it worked. Unfortunately, you most likely need a developer account to actually download the iOS 9.3 beta file as the public beta is unlikely to work with iOS 4.3. Nonetheless, if you manage to get hold of the iOS 9.X beta version then definitely give it a shot.
