My view on Android

Android is an operationg system developed by Google, and based on linux kernel.

It sees phenonmenal growth since 2009, firstly from mobile phones, then to tablets.

The growth pattern is also very similar to linux.

Linux, is now 20 years old, and is still growing / evolving rapidly. It's very grass-root style movement, based on GPL open source concepts. There's lots of info on the internet, free apps on Google Market.

Yet many says that the tablet market is dominated by iPad from Apple, but it's still similar scenario as "Linux vs Microsoft".

Linux did not try to compete with Microsoft, and shows no interest on it.

Similar belief is in Android. They promote a FOSS ( Free open-sourced softwares ) ecosystem, that let everyone to participate / modify your device.

It's same concept that "If you cannot open it, you do not own it"

Android may not become the winner in tablet market / mobile phone market, but it won't die.

I went to 桑達 tablet market in ShenZhen, and found that more than 80% of tablets are using Android, no iPads, and just a few Windows 7 + Atom tablets. Sadly, many of these manufacturers break the GPL rules, and do not release their source code !!

The new products are coming out rapidly, and yet many 5 ~ 6 months old products are already on sale with huge discount. Cash is king there. So the biggest players of Android tablet are those "no-name" white box ShanZhaiJi(山寨機) tablet makers.

CMOS sensor trends and astrophotography, from amateur astronomers perspective

Nowadays, even in low light conditions, digital camera can quality pictures with higher ISO, noise and hot pixels have been gradually reduced. Sony has introduced back illumination process for consumer market. Sony BSI sensors evolved  from Exmor to now Exmor RS( stacked) technology. This stacked technology allows further chip size reduction, which has strong demands in smartphone camera market. Digital astrophotography is also benefited from such advances, utilising Back Side Illumination technology Exmor: Within the CMOS sensor, it outputs low-noise digital signals by "on-chip column AD conversion" and "dual noise reduction" to suppress noise in the first half of the process In low light conditions, when a wide aperture is desirable to collect as much light as possible. At apertures wider than f/2.0, back-illuminated Exmor R sensors are significantly more efficient at collecting light than conventional, front-illuminated sensor...

ultrafast rendezvous to ISS

    14 Oct 2020,  being the first to use a new “ultrafast” rendezvous” scheme with the ISS. Following a flawless ascent to the correct orbit, Soyuz 2 .1a , Soyuz MS-17 caught up with the orbiting laboratory in only two orbits (three hours), halving the time it takes for crew to get to the Station.   The three space travelers of the Soyuz MS-17 mission launched on a six-month mission the International Space Station.  previous 3/4 orbit rendezvous: Soyuz MS-16 4 orbit rendezvous A three-orbit profile was deemed possible without major flight design changes after inauguration of the Soyuz 2-1A rocket that provides a much higher orbit injection accuracy than its predecessors and would allow the two correction maneuvers on Orbit #2 to be eliminated while the Automated Rendezvous Phase would still remain untouched. The deletion of the Orbit #2 maneuvers was expected to slightly tighten the already restrictive phase angle window from and upper limit of 30-35° to 25-28°...
