How to install pip and pipenv properly on Ubuntu 17.10

Ubuntu 17.10 comes with python3 3.6.3 installed by default but not pip and pipenv. We can install install pip systemwide and pipenv into the user local bin so we can use all the convenience when working with our python projects:

wget https://bootstrap.pypa.io/get-pip.py -O /tmp/get-pip.py
sudo python3 /tmp/get-pip.py
pip3 install --user pipenv
echo "PATH=$HOME/.local/bin:$PATH" >> ~/.profile
source ~/.profile

Update 9 Nov 2017: replaced curl with wget, thanks Peter

Generating Atom feeds from your Lektor site

After quickstarting a Lektor site, a next obvious thing to do is to add a feed to the site’s blog. Fortunately, Lektor has a growing ecosystem of plugins, one of them creates atom feeds.

Installation of lektor-atom

The plugin to install is lektor-atom, and is installed via the terminal:

lektor add plugin lektor-atom
lektor build

This adds a reference to the myproject.lektorproject file with the plugin and installs the plugin into the lektor pipeline.

Configure a feed

However, notice that after building the site no feed is generated! This is because no feeds have been setup yet.

Create a configs/atom.ini containing the following lines (full documentation)

[blog]
name = My Blog feed
source_path = /blog
item_model = blog-post
url_path = /blog/feed.xml

Change the url_path to suit your preferences. Trying to build now would result in an error: E blog/feed.xml (RuntimeError: To use absolute URLs you need to configure the URL in the project config.)

To resolve the build process myproject.lektorproject must be updated with two lines within the project section to indicate the site’s live URL and an absolute URL style:

[project]
name = My Project
url_style = absolute
url = https://myproject.com

[packages]
lektor-atom = 0.2

The site can then build and the resulting feed can be accesssed from https://myproject.com/blog/feed.xml.

Building on temporary foundations

Just came across an interesting perspective on frameworks by Timothy Perrett:

It is imperative to understand that the need for composability in our software tools is an absolute requirement. If we as an industry have any hope of not repeating ourselves time and time again, we have to change our ways.

I definately agree that we’re doomed to keep making the same mistakes if we’re building on top of frameworks and then switching them out for a different one, which I hadn’t considered before.

Automatic crash reporting using FogBugz for PowerShell

This morning I integrated our PowerShell processes into FogBugz by writing a small module that submits occurrences of all errors to BugzScout. You might want to do something similar so I did this write-up.

Broadly it works similar to BugzScoutLogWriter that I developed previously for integration with SilverStripe CMS. In this case however, we need to do the following things:

  1. Set the script to stop on all errors so they can be trapped instead of ending the execution of the script.
  2. Capture the error details and submit them to FogBugz
  3. Have an error occur. 😉

I’ve published the code in a Gist for you a have a look. I include the function in every script I use.
