Install pdflatex ubuntu

PdfLatex is a tool that converts Latex sources into PDF. This is specifically very important for researchers, as they use it to publish their findings. It could be installed very easily using Linux terminal, though this seems an annoying task on Windows. Installation commands are given below.

  • Install the TexLive base
sudo apt-get install texlive-latex-base
  • Also install the recommended and extra fonts to avoid running into the error [1], when trying to use pdflatex on latex files with more fonts.

TemporaryJam / Howto convert a PFX to a seperate .key & .crt file
Last active April 4, 2024 10:52
How to convert a .pfx SSL certificate to .crt/key (pem) formats. Useful for NGINX
source: http://www.markbrilman.nl/2011/08/howto-convert-a-pfx-to-a-seperate-key-crt-file/
`openssl pkcs12 -in [yourfile.pfx] -nocerts -out [keyfile-encrypted.key]`
What this command does is extract the private key from the .pfx file. Once entered you need to type in the importpassword of the .pfx file. This is the password that you used to protect your keypair when you created your .pfx file. If you cannot remember it anymore you can just throw your .pfx file away, cause you won’t be able to import it again, anywhere!. Once you entered the import password OpenSSL requests you to type in another password, twice!. This new password will protect your .key file.
Now let’s extract the certificate:
`openssl pkcs12 -in [yourfile.pfx] -clcerts -nokeys -out [certificate.crt]`

JoshReedSchramm / collection_check_boxes.html.erb
Created October 27, 2013 00:05
An example of customizing collection_check_boxes in Rails 4. -- I'm working on converting a rails 3.2 app to Rails 4 and noticed that a couple of helpers from simple_form are now in the Rails core. I wanted to move away from dependencies as much as possible including getting rid of simple_form if possible so I went about converting the old view …
<%= f.collection_check_boxes :venue_ids, Venue.all, :id, :name, checked: Venue.all.map(&:id) do |b| %>
<span>
<%= b.check_box %>
<%= b.label %>
</span>
<% end %>

# Description: Simple demo to showcase Redis PubSub with EventMachine
#
# Update 7 Oct 2010:
# - This example does *not* appear to work with Chrome >=6.0. Apparently,
# the WebSocket protocol implementation in the cramp gem does not work
# well with Chrome's (newer) WebSocket implementation.
#
# Requirements:
# - rubygems: eventmachine, thin, cramp, sinatra, yajl-ruby
