I’m playing Minecraft now.

I chose amplified world because its terrain is fantastic. But maybe due to it’s complex geometry, I found a lot of underground water while mining and it bother me.

I ordinaly wanted to automate the work by using scripts to learn programming, so I decided to take this oppotunity to install the mod, CC:Tweaked, a fork of CompuyterCraft, and write a script to build a wall(replacing the surrounding non solid blocks with solid blocks) while digging hole like the shielding construction method.

Story

One year ago, I bought MacBook Air. The purpose was replacing worthless time, like surfing internet with the smartphone on bed or train, to productive activity, like writing blog.

And now, I’d still not accomplished that purpose, I still addicted the smartphone.

Come to think of it, in the situation, such as trying to get up on bed or commuting in train, the standard laptops are still too large. At least, the replacement device of the smartphone need to be as small as possible to hold by one hand for using with lying down on bed and standing in train.

Try XP-PEN official driver for Linux

Circumstances

I replaced my display to new larger one.

Then, I decided also to replace my LCD tablet to a smaller non-LCD pen tablet because there has been no space for it.

As a Linux user, the trouble with such peripherals is that there are often no official drivers available for Linux.

Of Course, for Wacom products, which is the most major peripherals brand, there is an unofficial driver developed by volunteers so it can be used without problems… but Wacom is too expensive for me.

Case

A half year ago, I move Nextcloud and other services to new server. At that time, there was some error and alert had occurred. I fix only fatal error but not fixed other alerts.

I embarked on a modification of the rest of the warning.

{{ image(src=“alert.png”, alt=“Screenshot of alerts”) }}

Components

• AWS Lightsail
• Ubuntu 18.04
• PHP7.3 　　- PHP7.4 is activated too because of other application’s requirement
• Version of Nextcloud: 17.07,18.07 (Updated during this work)
• Web server: nginx
  • username: nginx

Update database

Alert say “Execute occ db:convert-filecache-bigint” then I do so

2019/08/28 Add some method about virtualization

History

When I captured Splatoon, I noticed that it’s convenient that I can serch information while loading. In addition, specified for foreign game, I want to search dictionary.

All pc games that I currently have will stop when the screen is inactive, so I can’t do this. Even if there are two screens with great pains, it does not make much sense. If the screen only stops, i still want to do something because I’m very anxious that the sound becomes a bump.

History

I decided to suspend the file server during the daytime on weekdays to save electricity, so I have to manually cancel the suspend on a public holiday weekday. This itself is unavoidable, but at least, I want to be able to turn on remotely via LAN from the main machine rather than the power button . So I try the fanction called Wake-on-LAN.

There is a strange phenomenon that the main PC returns from the suspend without automatically. I was observing it, and it seemed to wake when the refrigerator groaned.

It’s not actually link PC and refrigerator, so I think the mouse is picking up the vibration of the refrigerator.

So disable to return by mouse.

I thought it’s not enough to bother to make an article, but I posted because it was too cumbersome when I search it.
I think If you’re a gamer who want to capture gaming display, you must have Windows PC and use it to capturing.
In my case,I use Windows10 reluctantly for only PC games, so I want to do something as much as possible on Linux,
but it would be a rare case.

Circumstance

Less than half a year to move the PC to homebrew NAS. Because of lack of budget, My NAS has single HDD,
but now, I want to buy additional HDD and build mirroring to save my data

At first, i was going to build a raid1 with ext4 and motherboard function, but after research, I decided to install a file system called ZFS. The reasons are following,

• The file system itself supports RAID
• Many useful functions such as transparent compression and snapshots
• It eats cpu and memory, On the other hand, I can think that make good use of my NAS’s specs.
