Let's say you have a Bash shell script, and you need to run a series of operations on another system (such as via ssh). There are a couple of ways to do this.

First, you can stage a child script on the remote system, then call it, passing along appropriate parameters. The problem with this is you will need to manually keep the remote script updated whenever you change it -- could be a bit of a challenge when you have something to execute on a number of remote servers (i.e., you have a backup script running on a central host, and it needs to put remote databases in hot backup mode before backing them up).

Another option is to embed the commands you want to run remotely within the ssh command line. But then you run into issues with escaping special characters, quoting, etc. This is ok if you only have a couple commands to run, but if it is a complex piece of Bash code, it can get a bit unwieldy.

So, to solve this, you can use a technique called rpcsh -- rpc in shell script, as follows:

First, place th

Hyperlinks (a.k.a. HTML-like anchors) in terminal emulators

Most of the terminal emulators auto-detect when a URL appears onscreen and allow to conveniently open them (e.g. via Ctrl+click or Cmd+click, or the right click menu).

It was, however, not possible until now for arbitrary text to point to URLs, just as on webpages.

In spring 2017, GNOME Terminal and iTerm2 have changed this.

GNOME Terminal is based on the VTE widget, and almost all of this work went to VTE. As such, we expect other VTE-based terminal emulators to catch up and add support really soon. Other terminal emulators are also welcome and encouraged to join!

Mapping Caps Lock to simultaneous Esc and Super (Mod4)

The CAPS key can be mapped to an escape key when pressed once, and a super (mod4) key when used in combination with other keys.

Create the file /usr/share/X11/xkb/symbols/custom_opts with the following:

// Make Caps an additional Escape
hidden partial modifier_keys
xkb_symbols "super_esc" {

key { [ Escape ] };

Hey everyone - this is not just a one off thing, there are likely to be many other modules in your dependency trees that are now a burden to their authors. I didn't create this code for altruistic motivations, I created it for fun. I was learning, and learning is fun. I gave it away because it was easy to do so, and because sharing helps learning too. I think most of the small modules on npm were created for reasons like this. However, that was a long time ago. I've since moved on from this module and moved on from that thing too and in the process of moving on from that as well. I've written way better modules than this, the internet just hasn't fully caught up.

otherwise why would he hand over a popular package to a stranger?

If it's not fun anymore, you get literally nothing from maintaining a popular package.
