Using xclip to copy terminal content to the clip board:
Say you want to pipe shell output to your clipboard on Linux. How would you do it? First, choose the clipboard destination, either the Mouse clip or the system clipboard.
For the mouse clipboard, pipe straight to xclip:
echo 123 | xclip
For the system clip board, pipe to xclip and select clip directly:
So you’d like to contribute to Clojure, great! Let’s talk about what that involves.
The first thing you’ll want to make sure is that your idea is valid, and that you won’t spend a ton of time working on something that won’t make into master. To do this, you should create a JIRA ticket. For example, let’s say we want to improve how core.async handles channel closing propagation. It’s not a super complex problem, but there are some design questions about which of the various semantics currently in place should be the default, and if some semantics should be configurable.
So start by making a JIRA ticket and stating what the problem is you’re trying to solve, what the possible options for solving the problem. Now hit save and wait for the ticket to be triaged. Alex Miller will take a look when he can, and that can take a few days to a few weeks, depending on the time of the year (he has other responsibilities). Alex may out-right reject the idea if he knows Rich would never approve the ticket, but otherwise h
| # Generate a new pgp key: (better to use gpg2 instead of gpg in all below commands) | |
| gpg --gen-key | |
| # maybe you need some random work in your OS to generate a key. so run this command: `find ./* /home/username -type d | xargs grep some_random_string > /dev/null` | |
| # check current keys: | |

| # See your gpg public key: | |

| # YOUR_KEY_ID is the hash in front of `sec` in previous command. (for example sec 4096R/234FAA343232333 => key id is: 234FAA343232333) |
When [Markdown][markdown] appeared more than 10 years ago, it aimed to make it easier to express ideas in an easy-to-write plain text format. It offers a simple syntax that takes the writer focus away from the formatting, thus giving her time to focus on the actual content.
The market abunds of editors to be used for help with markdown. After a few attempts, I settled to Sublime and its browser preview plugin, which work great for me and have a small memory footprint to accomplish that. To pass the results around to other people, less technical, a markdown file and a bunch of images is not the best approach, so converting it to a more robust format like PDF seems like a much better choice.
[Pandoc][pandoc] is the swiss-army knife of converting documents between various formats. While being able to deal with heavy-weight formats like docx and epub, we will need it for the more lightweight markdown. To be able to generate PDF files, we need LaTeX. On OSX, the s
