Silicon Valley and Hi-tech

I grew up with a dream of doing something in the "Hi-tech" industry. Back then I imagined it will be some breakthrough scientific work like inventing a perpetual energy machine or engineering a space elevator... something that will fall under the category of rocket science.

They say Silicon valley "is home to many of the world's largest technology companies". No doubt, any young technologist like me had his eyes set on Silicon Valley. So when I compare the nature of today's so-called "hi-tech" hot companies, namely Facebook, Twitter... I can't help but wonder where is the Science and Technology in them?

This morning I read Sarah Lacy's Techcrunch article "Silicon Valley at a Cross Roads: Entertainment or Science?" and it all made sense.

She put into the words the very question that lingered in my mind.
Will it [Silicon Valley] follow the Web 2.0 path further down the road of media and entertainment or go back to its roots of hardcore science and technology?
According to her the valley made a choice between real hi-tech and Web 2.0 (that would lead to media innovation), back in early 2000s.

But in the early 2000s, the Valley was at a crossroads. Was the future cleantech or Web 2.0? Put another way, was the future starting a new stack or continuing to iterate on top of the mostly-built out one? The cleantech camp was championed by a lot of top Valley names– most famously John Doerr– who saw it as the most important way to change the world and an undeniably huge market that required real innovation. The Web 2.0 camp was championed largely by the PayPal Mafia’s angel investors like Reid Hoffman and Peter Thiel, and a handful of other angels and mentors like Marc Andreessen. Many of them prized the fact that Web companies were the opposite of cleantech: Thanks to decades of technology build out they were cheap and low-tech to start, utterly changing everything about these companies from the size of the exit you needed to have a good return to how quickly you could know if you had something or not.
Ultimately, Web 2.0 won the Valley’s heart and hype....
She then makes a logical guess about future that the valley will continue down "a path where San Francisco becomes the center of Web media, the way New York was the center of news media and LA was the center for entertainment media. These businesses are easier to understand, quicker to evaluate and more likely to produce a series of newsy blog posts"

I have to say, her post brought a moment of clarity to me this morning. You should read the entire article. Few people have the ability to observe a big industry over a long period of time and make sense about where it came from and where it is leading. Sarah Lacy is one of them.

My understanding and my hope is that even though Silicon Valley takes the route of a media industry, their will be "real" hi-tech innovation somewhere in the world. I feel confident about it when I read about Elon Musk's Tesla and SpaceX, Richard Branson's Virgin Galactic, or the Mega Machines episodes on Discovery channel that show behemoth engineering projects in China, Japan, S Korea. I also find promise in the grassroot culture of "Makers" that is taking shape in the form of Maker faire and the new industry of personal manufacturing that is evolving in the form of 3D printing. Hopefully we will build on top of the Web infrastructure that Silicon Valley provides and the true hi-tech innovation will take place in this virtual world and not in a specific physical valley.

Indirect experiments

I like how some advanced experiments in science are fantastically indirect. Take for example this experiment of measuring mass of proton (source).

For each hydrogen atom, the team replaced the atom's electron with a particle called a muon, which is 200 times more massive than an electron.
"Because the muon is so much heavier, it orbits very close to the proton, so it is sensitive to the proton's size," said team member Aldo Antognini, of the Paul-Scherrer Institute in Switzerland.
Muons are unstable, and they decay into other particles in just 2.2 microseconds. The team knew that firing a laser at the atom before the muon decays should excite the muon, causing it to move to a higher energy level—a higher orbit around the proton. The muon should then release the extra energy as x-rays and move to a lower energy level.
The distance between these energy levels is determined by the size of the proton, which in turn dictates the frequency of the emitted x-rays.
But based on the accepted proton radius, the experiment failed to produce x-rays at the anticipated frequency.

ReaderScope 2.0.6 - Find Comments

If you didn't notice, in recent releases the Digg and Reddit social beacons were missing. They were removed some time ago to make space for a better method of discovering comments. I had released a stand-alone app FindComments few weeks ago. It uses ContextVoice to find comments from all sources (Twitter, Digg, Reddit, and many more). In v2.0.6 that app is integrated with ReaderScope. You will see a new icon on the action panel, which you can tap to find comments on the current news item from all over the web.


Try it on some popular news stories from Slashdot or XKCD to see how it works.

ReaderScope 2.0

ReaderScope 2.0 is out in the Market today.

As explained in last post, the rules of free have changed in this version. Instead of giving a crippled version for unlimited time at no cost; now ReaderScope will be available in its full glory but for limited time - 5 days. After that you can buy the Value Pack for $2.49 and unlock the expired version.





Enjoy!

ReaderScope upcoming changes

Last weekend I released ReaderScope 1.9.8. It has some changes that should fix crashes that some users have reported in comments at Android market. These crashes went unnoticed for such a long time, because I didn't see them myself during my testing and they were not captured by the built-in crash reporting mechanism. But I found about them last week, thanks to Android market's new crash report collection mechanism. One frequent crash was happening in the background download service and it wasn't captured by RS's crash handler. It should be fixed in v1.9.8. So thumbs up to Android team for adding this new facility to Market.

But this post is mainly about what's coming next. For starters, the version number will now graduate to 2.x. And then there will be a key change in the way free version of ReaderScope works.

Right now you can download ReaderScope from various market places for FREE. It has the basic look, with what is known as Legacy color scheme. It has Ads below the news screen. It has a handy widget, but it cannot be refreshed unless the app is unlocked with Value pack. The value pack is available for $2.49. Once you buy it and enter the unlock code, you get full access to 3 additional themes, no Ads, fully functional widget and ability to see favicons against your feeds.

Starting with 2.x, you will be able to access the full functionality of ReaderScope right out of the box, when you install the free app from any market place. The default color scheme will be changed from Legacy to Night (which so far I've heard is most popular), but you can change to others if you want. There will be no ads. You will have fully functional widget (If you are like me, you will read half of your news via the widget). The favicons will be visible.


So what's the catch? The free version will expire in 5 days. You can buy the Value pack for $2.49 and unlock it.

In addition, support for Android 1.5 will be dropped.

Why this change?

There are couple of reasons.

1. The default (legacy) color scheme is super dull. And yet, that's the first impression users get when they download the free app. I have read many users complaining about the "awful" UI of ReaderScope, and I believe part of it is the dull color scheme. So even though some pretty color schemes are hidden in the app, users don't know about them until they dig down 2 layers of settings and see the theme previews.

2. The admob code can make the UI sluggish on slow networks. When the app starts, the admob jar downloads an Ad over network. So if the network is slow, this request can sometimes add to the startup time of the app. And the worse part is, it happens even when you have unlocked the app. With the unlocked app, you won't see the ads, but I don't have control over admob code and make it stop fetch that one ad at startup. With 2.x, admob jar will be completely removed.

3. Dropping support for 1.5 had to be done someday. Only after that features from 1.6+ SDKs could be used. I hope, the users stuck with 1.5 will soon get updated by their carriers (or they will start using cyanogen like me ;).

The 2.x version will make no difference to users who have already bought the value pack, they will keep getting updates as usual. Others who have been using the app without the Value pack, will see a 5 day expiration notice upon upgrade. They will need to buy the value pack within that time.

However, if you are happy with the way free ReaderScope is right now, you will have an option. You will find v1.9.8 apk available for download here. Obviously, it won't get any fixes/features, but the app is quite stable as it is today and you can use it for free if you want. However if you want ongoing fixes and features, you will have to upgrade to 2.x and buy a value pack within 5 days.

First 2.x release should hit the market around next week. Till then please, let me know your feedback on this change.
