EOS Knight has been my daily mobile game after quitting my last mobile gaming addict. I regard the mobile gaming is one of the worst habits to waste time, but the good thing about EOS knight is that I actually don’t have to spend a lot of time on it due to its idle gaming mechanism.

To me, the motivation of playing this game is puremaking some EOS so the marketplace for materials and equipment is my main focus.

The game recently introduced a new update

Hitting over 700 floors now will allow players to sell 4 items at the same times which is 1 item more than the previous limit. Definitely sounds interesting for a heavy trader like myself.

I’ve been staying at 500+ floors for quite a while and kind of making back all my initial EOS. It is the right time to go for a higher floor, at least beyond the 700 ceiling. I’m ready to splash those EOS again!

Made my most powerful equipment

The only way to achieve that is upgrade equipment of knight so they can either deal more damage or staying alive longer. Long story short, I made a new armourMare Tranquilitatis which happens to be the most powerful item in my collection.

The item is 90% done and here is the plan that is going to be completed anyhow: Make 16 same items and synthesise them all together into one for max levelling it to Level 5.

And the breakdown of cost is:

• About 1 EOS / Item
• About 3 EOS for the cost of Magic water which acts like the fee for such operation

(1 * 16) + 3 = 19 EOS

At the time of writing, 1 EOS = $5.59 which make the item cost about $106.21. Oh my Fxxking God. This alone will tops all my game spending record combined!

It is my most expensive spending in a damn game so far

To be honest, I’m not even mad. I was fascinated by this fact and I did not realize the actual cost while I was busy crafting the item. It works like charm though and does what it does to bring my game to another level. And in fact I could just sell it away at the same cost price at least(it is a damn fine item anyway). While I do not regret crafting expensive item as such, this is a whopping price to pay though.

The lesson of this post is, gaming using crypto could be dangerous as betting in the casino with chip. Players often ignore the actual value of the token. We often treat one chip as one unit despite the actual value it carries no matter it worth $5 or $100 a piece.

And that explains very well in my case as I calculated the value in term of EOS instead of converting them to the daily updated price at CMC before making a decision. Which would anyhow make the game a lot more troublesome to play with right?

While this powerful and sexy amour starts to show, I hope the value would retain more or less the same in the market by the time I decided to let it go. Else it would be a huge loss, ouch!

What is your most expensive investment in a game?

Grew more comfortable with digital drawing and started to draw with the “digital” in mind. When you started to apply some techniques that is only applicable in digital art, you are getting away from the old ‘paper-and-pen’ kind of traditional art thinking.

Tried to use the mirror effect for the first time for the reflection of upper half picture. Toned the reflection with heavy shades and some ripple effects, Tada! A nice reflection is done within 5 min of work which is simple unachievable with physical tools.

今天第一次去了工作外的的正式专业培训，内容是我近来很感兴趣的 Cyber Security Forensic，也就是系统被黑之后要如何保护和分析起因的技术课程，非常的有趣。只是第一日的课程上发生了一些小插曲，让我感触良多，课程的内容容后再分享吧。

这个为其数天的课程只有寥寥九人参加，开课不久后，导师就要求来个简单的破冰仪式，每个人都简单的自我介绍起来。轮到一个不起眼的大叔时，就叫他中年先生吧，中年先生第一句话就让兴致正高的导师有点呆住了。

两个星期前，我被裁员了。

没有我们之前一般“我来自哪里哪里”“我从事什么什么行业”的例行开头，却一句话就把全班的主要力拉过来了。

周遭的反应可能也早在中年先生的预料之中，在导师的询问之下把原因循循道来。我却没有继续留心谈话的内容，因为那几乎都是千篇一律的故事。

有点撼动我心神的是，中年失业这件事情原本在看起来于我是遥不可及的事情，忽然间有点可以看到点眉目了。不是说我就快失业了，离中年也还有段距离，可能眼前同行前辈的遭遇更容易引起共鸣吧。

开始打量起中年先生，约莫四十出头，身形干瘦，肤色黝黑和初显的皱纹让看他看起来比实际年龄要老，穿着一身符合他的年代的宽松西服，谈吐之间比起他身后的后生小子内敛许多。与其说内敛，还不如说小心翼翼，阴声细气的，是被生活的压力活生生活成了这个样子。仰或是听过了他的“背景”后让我我先入为主了？

不知何时，心里不知不觉的把自己代入了他的角色。到了那个年纪，应该有妻儿了吧，有房贷了吧，赡养父母的重担全在肩上了吧。在这么个经济压力最重的阶段被辞退了，心里活动会是如何呢？

Damn，我可不想这样子。

就在中年先生正在分享打算如何借着这类课程转型到另一个行业时，另一个有点社会资历的学员说了句很合我胃口的话，

Start something, don’t bother looking for another job.

着啊，到了这一把年纪，勤奋工作的话，资历和见识都有了，资本和筹码也远比后生小子积累多了，与其再低声下气的去打工，现在不正是最好的 work for yourself 的时机？

Nah, 才没那么容易。

如果不是在年轻力壮的年纪就有所准备，自雇这条路不是说走就走的。起码，起走不难，要有善终就不是那么容易了。我不想变成二十年后的中年先生，但是此刻的我，有开始在准备了吗？

After the failed attempt in installing steem-python in Windows. I decided not to waste more time on solving the problems and move on to a Ubuntu virtual machine which is practically a more friendly environment for such work.

Install VM and set up Python environment via Anaconda

Anaconda is the recommended python environment by the official document. After installing Ubuntu in Virutalbox which is quite straight-forward, I proceeded with the git clone method instead of the pip as the former would be getting the source code from official github repository.

sudo apt install git
git clone https://github.com/steemit/steem-python
cd steem-python
sudo make install

Errors in the installation

Here are the common errors the installation will hit under Linux environment and already being reported by many users.

scrypt-1.2.1/libcperciva/crypto/crypto_aes.c:6:10: fatal error: openssl/aes.h: No such file or directory
#include <openssl/aes.h>
          ^~~~~~~~~~~~~~~
compilation terminated.
error: Setup script exited with error: command 'x86_64-linux-gnu-gcc' failed with exit status 1
Makefile:18: recipe for target 'install' failed
make: *** [install] Error 1

Traceback (most recent call last):

    from pkg_resources import load_entry_point

    raise DistributionNotFound(req, requirers)
pkg_resources.DistributionNotFound: The 'scrypt>=0.8.0' distribution was not found and is required by steem

This is mainly due to the Ubuntu system was not able to find the scrypt package which can be easily fixed by

sudo apt-get install libssl-dev

Or as suggested by the official doc

brew install openssl
export CFLAGS="-I$(brew --prefix openssl)/include $CFLAGS"
export LDFLAGS="-L$(brew --prefix openssl)/lib $LDFLAGS"

Test and done

Use python to enter pyton prompt mode and test with the simple get_account function and it works.

Test with steempy which is a practical CLI utility for Steem and it should be working without errors too.

Finally I decided to try out the command line of steempy to interact with Steem blockchain after being in the ecosystem for over a year. My recent personal little project needs to me to know more about the fundamental of how Steem system is working.

However, this blog is about how did I not manage to get the steempy installed successfully on Windows.

The errors I was too lazy to solve

So here is the failed procedure for the sake of recording in case I figured out the way to get around with it in the future.

Download the Anaconda for windows as suggested by the official document.

Installed the Anaconda successfully. Then open up the Anaconda Prompt and type in the command below to install steem-python.

pip install steem

Quickly, some errors poped out in my way:

1
2
3
4
5

Failed building wheel for ujson
Running setup.py clean for ujson
Failed to build ujson

distributed 1.21.8 requires msgpack, which is not installed.

The solution should be as easy as:

1
2

pip install msgpack
pip install ujson

Now the ujson should be fine and let’s deal with the second error which is particularly exclusive in Windows platform:

1

error: Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual C++ Build Tools": http://landinghub.visualstudio.com/visual-cpp-build-tools

Seems like I have an outdated Microsoft Visual C++, easy, just go the official Microsoft site and get the Visual C++ Build Tools.

Installed a few essential or probably bloat plugins that might not be needed in this case.

The installation took a while, rebooted the PC after that and sadly the errors still remains as I pip install steem once again.

Windows is a disaster for such an attempt

To be honest I have close to zero experience in development in Windows environment so it would be fair to say it sucks but at least it is not a friendly environment for steem-python.

Let’s move on and try it on my Lubuntu virtual machine instead. Damn, I’m not a good sysadmin and I know it.

Did not see the advantage of this hardfork yet but undoubtedly HF20 is a failure up to this point. This also exposed how fragile the DPOS blockchain system is, it is possible to go down while the Bitcoin with ancient blockchain tech never went though event like this even for a single second.

Also I cannot understand why something buggy at such level would not be discovered in thw testing phase. Don’t we have a testnet?

Please beware that the Steem reputaion is at stake on such even @steemitblog.
