* Fix judger/log/
* fix(judger): Let judger work on ubuntu 20.04
Judger stops working since 9a6f16cf1d, this commit allows judger continue working.
* fix(web): update faq.php
Currently, if there is only one subtask, the bulitin judger automatically enters the ACM mode.
However, if the subtask has type "min", the judger should not do this. This commit fixes this bug.
Since the phpv8-v8js plugin did not fully support PHP 7.4 and there is no new package on pecl...
Every time we need to make some 魔改 on this because official provided versions are always too old...
Let's welcome brand new look made by Bootstrap 4!
Not only website but also our logo is being flat now.
The new logo uses blue as main color, to be different from original.
For us, it also shows the project has up to a new stage.
We hope that the project will get better and better.
BREAKING CHANGE: The path for users to place their images is renamed.
Logos are saved as new names too. Users should move "pictures" to "images".
Any modifications should suit the Bootstrap 4's standard.
There are some situations that need to place subfolder in data path.
If there is any file but not only folder in path, do not move.
Previous moving logic did not check about this.
For only web, there is no need to build checkers.
There are so many checkers that will slow down make speed.
Also for some situations, users can build checkers without runners.
Without bundle, now you can choose to download single container.
For example, you can only download judger container to setup a new judger.
Also, the web container now no db and judger containing, except local sandbox.
You can use docker-compose to get every single container work together from now.
Single DB this time uses the latest MySQL 8 version, so some preferences are different.
The runtime versions on faq page are very old and not edited.
If judger is not with web, we can't determine the exact version.
So set these versions as default show, won't be too much different.
We add a new way to access blog page. Now there are 3.
The switch now uses number to choose the way.
1 is for subdomain and 3 is for subfolder.
2 is for separated blog domain with its subfolder.
For example, mike's link is blog.xxx.xxx/mike.
Blog list page link on navbar will change by domain mode.
