Book notes: Remembrance of Earth's Past and Six Wakes

Recently, I've read two fascinating sci-fi books:

Remembrance of Earth's Past is a trilogy and quite long. IMHO the 1st book is the finest (endorsed by George R. R. Martin, Mark Zuckerberg, Barack Obama,...). Some notable points:

  • The wall we are facing in science: We are trying to understand atoms & sub-atom particles, but not much luck. We cannot build faster computers, or better materials (super strong, super durable,...), and other things because of this. Think about this: how great it is if we can manage/control atoms as easily as we can do with bricks?
  • How would the future look like if studying atoms is banned today? In the book, alien "locks" our LHCs, and we cannot study atoms anymore, so in the next 400 years, we have to develop technologies with a current understanding of science. Spoil: it's still okay, but not very okay if we want to be a more advanced civilization.
  • If the Earth is threatened by the alien, are we allowed to escape (to a different Solar System)? Should we allow guys like Bezos, Musk to ride away on their luxury ships with their families, while most of us are waiting to die here? Spoil: they are not allowed lol.
  • A more general question that includes 1.3: should we be open-minded, and think about multiple solutions for one problem, or do we have to force everyone into "our" one solution only? Should we forbid studying some particular fields? Some questions:
    • Should we escape to other Solar Systems, or just in our Solar System is enough?
    • Should we study/develop various kinds of space engines?

Six Wakes is "softer" than the trilogy above, and is more about mystery/crime. Say, given that we have perfect cloning technology (that can "copy" both flesh & memory, maybe with some modifications if needed):

  • How would the society on Earth change? How would people and religions react/adapt to this?
  • How is it like to live in a multi-generation interstellar spaceship (actually, just a small group of people, but they would be cloned after death)

All my games and apps on Google Play are now free (and no Ads)

Games and apps by Alsatian Studio

I used to make paid games without ads & iap (but earned almost nothing because my games are too simple, and people don't want to pay for them -- that's reasonable)

But recently, I've thought about making free games without ads & iap (basically games like the good old time), because I have a full time job and don't really need much money; and if my games go viral, I may find other way to monetize (ask for donation?). But I've pretty busy & lazy lately :(

Now I think I should not postpone anymore, starting by making current games free. You can check them here:

How to Upgrade Ubuntu 18.04 to Ubuntu 20.04.1 (Available Now)

Ubuntu 20.04.1 was released on August 06th 2020, but is not available to be upgraded for 18.04 users (until today - Sep 30th). That was a really long wait (I've been a bit frustrated, to be honest), but now it is here.

So, to upgrade to 20.04.1, just doing these simple steps:

1. Upgrade the installed packages of Ubuntu version 18.04
$ sudo apt update && sudo apt upgrade && sudo apt dist-upgrade && sudo apt autoremove && sudo apt autoclean

2. Upgrade Ubuntu
$ sudo do-release-upgrade

Note: just type "y" & Enter if asked.

A short and clean "About Me" template in HTML & CSS

I just made a concise "About Me" template page (with HTML and CSS only). You can host this for free on github (like me). This may impress your potential recruiters, because building and setting up your own page is cooler than using existing services like

You need to know basic HTML, CSS and GitHub Page.
