As a programmer

We all know how useful hotkeys can be and we usually try our best to make good use of them.

More ever, some terminal features can only be accessed via keyboard shortcuts, making them as important as water and air to our daily life.

Mounting a volume from host

was very easy for docker.

Specifying whether the host volume should be readonly or read/writable was also very easy.

Sample command:

1
2
3

-v "$(pwd)"/target:/app
-v "$(pwd)"/target:/app:ro
-v "$(pwd)"/target:/app:rw

But when your mounting a volume from host with SELinux enabled, things can get a little more complex.

GitHub pages were everybody’s favorite

It is not very surprising, for a very long time, if you see a developer with a GitHub account, then you will also find out he/she is hosting something on GitHub pages.

Either it could be his personal homepage, blog or project intro.

I personally really appreciate how GitHub invented gh-pages branch for hosting GitHub pages.

Gatsby believed in the green light, the orgastic future that year by year recedes before us. It eluded us then, but that’s no matter— tomorrow we will run faster, stretch out our arms farther… And one fine morning——

Docker containers can be binded to multiple interfaces

Each interfaces comes with a dynamic IP address.

Think about following scenario:

• In your Docker compose file you specified your DB and Web service.

• You bind DB to internal network interface.

• You bind your web service to both your internal network interface and external interface.

• You want your Web service only bind to external interface.

• How do you do that?

The way to use append in Golang

is described as following:

1

a = append(a, x)

because append may either modify its argument in-place or return a copy of its argument with an additional entry, depending on the size and capacity of its input. Using a slice that was previously appended to may give unexpected results.

Still remember the days…

however hard you try,

• your program refuse to compile?
• your program may compile but crash immediately when start?
• your program may start but won’t produce correct results?

We accept the love we think we deserve.

It is not a lack of love, but a lack of friendship that makes unhappy marriages.

Keep true to the dreams of your youth.
