As a software engineer, he/she needs to have the hard skills especially writing source code, debugging. He/she needs to know multiple programming languages (eg C, C++, C#, JavaScript, Python, etc). It will be even better if he/she can write tests, adopt TDD, write clean code, do refactoring, know how to implement various algorithms (search algorithm, sort algorithm, dynamic programming, etc), review code. These are all hard skills.

However, in order to perform well in the working environment, software developers are recommended to adopt several soft skills. These skills will help the team to improve the productivity.

In my previous post, I mentioned I have boot issue. Then I asked in Arch Linux BBS, and I got some useful advice from other users. As a result, I contacted a computer shop in my town, in order to get a hard drive (HDD). However, the shop doesn’t have 7200 rpm HDD. Then he suggested SSD to me, which is 1T storage. The SSD now is much cheaper comparing to two years ago.

Recently, I failed to boot into my laptop. I was shocked.

home contains a file system with errors, check forced.
home: Inode 12976129 seems to contain garbage.
home: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY.
        (i.e., without -a or -p options)
fsck failed with exit status 4.

Then not able to mount the home partition, I was prompted to login as root. However, I was too nervous, I forgot what is my root password.

In my previous post, I mentioned about using C# for Godot Mono. However, recently I found that, due to MonoDevelop is inactive, it causes my personal project not able to be built. As a result, I have to change the build tool to dotnet CLI. This can be set through

Godot (Mono) > Editor > Editor Settings > Mono > Builds > Build Tool

Besides that, I also changed the External Editor from MonoDevelop to Visual Studio Code. Visual Studio Code is nice for the C# project. It has autocompletion and able to find function definition and function references.

I was using Dell Vostro 5459 previously. However, it has some hardware deficiencies. The battery capacity keeps dropping drastically within a year. That’s a very bad experience. Now, the fully charged battery is only 1% of the designed capacity. Then I purchased an external power bank from Dell. But that’s not an ideal design for a laptop that you need to bring extra gadget to everywhere, and charging external battery is too troublesome.

In my previous post, I mentioned about reviving old Samsung Galaxy Tab 10.1. Today continue some extra customization works.

Firstly, the problem of the headphone mode emerges again. I tried to clean with cotton, but it doesn’t help. At the end, I found a page recommends an app (Disable Headphone(Enable Speaker)). I tried to install the app, and it works. It really works. That solves the most critical problem of my tab.

Other than that, I have installed several useful apps. They are

I bought a Samsung Galaxy Tab 10.1 many many years ago. But recently, I am trying to revive it so that, it will be a possible solution to allow my son to watch cartoon on an old tablet, in future.

Reviving this Galaxy Tab (P7500) takes me so much time to try out those custom ROMs and the apps. But it is an interesting experience.

I tried several ROMs, flashed with TWRP.

Previously installed Arch Linux on my wife’s old MacBook Air. Then just recently, due to the need of using Zoom Meeting on a device, I tried to re-use this MacBook Air again.

Sadly, Mac OS X 10.6.8 is not supported anymore. I cannot install latest Google Chrome, latest Firefox, or Zoom. The only solution is running Linux on it.

First of all, I have to update Arch Linux. However, the last update was in November 2019. Due to WiFi driver issue (slow, damn slow!), I just remove all unnecessary packages, such as LibreOffice, Wine, SMPlayer, Audacious, etc, and do the upgrade according to this forum post.

Med version 3.7 released.

The custom search feature now allows other scan types (int8, int16, …, int64, float32, float64), including the operators. Now also supports int64 scan type, which can be found in 64-bit games.

Besides that, there is new operator “”, which acts like “search within”. I use it as a shortcut for search within, especially search the float number we see in the game, 999, which may be 998.999 or 999.1111. By using “”, it will translate to search within [998, 1000]. It allows second argument, as “± x”. Without second argument, it is “± 1”.

I just revived my very old hobby project, Musgen.

I was interested in artificial creativity, was intended to advanced my study of doctorate on this topic. However, due to lack of the expertise in the local universities, I didn’t advance my study on artificial creativity.

Imagine that, if I can generate musics, then I can create my own game with any random background musics.
