hexagonal Django
by Jonathan Hartley Sept. 11, 2014

Sept. 11, 2014

The last few weeks I've been thinking about the architectural pattern known as Clean, Onion, Hexagonal, or Ports'n'Adaptors <http://blog.8thlight.com/uncle-bob/2012/08/13/the-clean-architecture.html> (http://blog.8thlight.com/uncle-bob/2012/08/13/the-clean-architecture.html). I'm curious if many people are applying it in the Django world? I haven't, yet, but I'm thinking of refactoring a vertical slice of our monster Django app into this style, and I'd love to hear if you think it's crazy / brilliant / obvious / old-hat, etc. Jonathan -- Jonathan Hartley tartley(a)tartley.com http://tartley.com Made of meat. +44 7737 062 225 twitter/skype: tartley

TDD stuff in London, next two weeks (and list comprehension scoping)
by Harry Percival June 1, 2014

June 1, 2014

Hi Uk-Pythoneers! *(with apologies to the wise ones amongst us who have chosen to live well away from the Big Smoke)* I'm involved in a couple of Python/TDD things in the next couple of weeks, both free to attend: Outside-In TDD and Test Isolation: https://skillsmatter.com/meetups/6410-outside-in-tdd-and-test-isolation-how… (all about testing, isolation, mocking, and the pains thereof... it may to provide some insight into the #TDDisDead / DHH controversy, if you've been following that) Introduction to TDD workshop with Andrea Crotti: https://skillsmatter.com/meetups/6424-obey-the-testing-goat (a gentle introduction to TDD with Django, for anyone that can't make it to EuroPython this year) Hope they're of interest! HP PS Can I have a little moan about generator / list comprehension scoping in Python 3? I just ran into this: https://stackoverflow.com/questions/11669379/undefined-global-in-list-gener… -- so now I can't use variables from the enclosing scope inside my comprehensions? that sucks! Doesn't it? -- ------------------------------ Harry J.W. Percival ------------------------------ Twitter: @hjwp Mobile: +44 (0) 78877 02511 Skype: harry.percival

The Bodleian Library is looking for three new developers, working on a variety of python frameworks. Primarily Django and Pyramid, with some legacy applications on Pylons.

Openworm - act now!

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I normally don't do this.

Python devs wanted at "Made", Notting Hill
by Jonathan Hartley May 19, 2014

May 19, 2014

Hey all, We're recruiting! Permanent, office in Notting Hill, on site only, small flexibility in hours in times of need, but mostly sorta 8 till 5 or 9:30-6:30 ish. My employer is "Made" (http://made.com), a 4 year old, 100 person company, which commissions, imports, and retails swanky furniture for decent prices. The business model eliminates middlemen and aims to sell most items while they are on a ship which is just about to reach England, thus reducing lead times, transportation and warehousing costs. My team is the 5-person Python "ERP" team. ERP stands for "Enterprise Resource Planning", and means the logistics of slogging parcels around between factories, warehouses, containers and customers. To do this, we use a popular framework called "Odoo" (was "OpenERP"), that feels a little like using Django in some ways. You won't be working on our website, which is handled by a separate 10 person PHP team who sits adjacently. They have impressed me with their professionalism and competence, but nevertheless we exchange good-natured broadsides from time to time to keep them in check. There are some fun technical challenges that we're just beginning to get stuck into, a smashingly sane CTO and senior management, and the environment benefits (IMHO) from a Nathan-Barley-like army of youthful "creatives", downstairs, who do various product design and photo shoot kinds of work. It's all leggy folks draped over sofas (showroom is onsite) and "flowers for the model" on expenses, which brightens up both office life and company pub trips. Hit me up if you're interested.

Fwd: [The-London-Python-Group-TLPG] Could you coach python students at OpenTechSchool this monday 12th May?
by Harry Percival May 9, 2014

May 9, 2014

London only I'm afraid, but if anyone is free 6:30PM til 8PM on Monday next week, these guys would love to hear from you! ---------- Forwarded message ---------- From: Antonio Cavallo <a.cavallo(a)cavallinux.eu> Date: 9 May 2014 20:39 Subject: [The-London-Python-Group-TLPG] Could you coach python students at OpenTechSchool this monday 12th May? To: The-London-Python-Group-TLPG-announce(a)meetup.com Dear pythonistas, we received from Gen Ashley on behalf of OpenTechSchool this urgent request: Dates: 12th May 2014 and 19th May Place: The Skills Matter eXchange, 116-120 Goswell Road, EC1V 7DP, London Time: starts at 18.30 OpenTechSchool would like to invite you to coach for one of their free classes offered to new learners of Python. We are holding our third batch of classes (2nd batch for Python, which is proving to be popular to learners) this MONDAY, MAY 12 and next MONDAY, MAY 19, but we are currently short on Python coaches. In case you wonder, here is a link to a short coaching guide - which describes how the classes are run: http://opentechschool.github.io/slides/presentations/coaching/ [2]. There are around 60 learners signed up (with 30+ more on the waiting list) and we will need around 4-5 more coaches. Developers don’t need to commit to both dates, but it will be nice. Here is a link to the "Beginners Python learning materials": http://opentechschool.github.io/python-beginners/en/index.html. [3] The classes will be held at SKILLS MATTER, Goswell Road, London from 6:30pm to 8pm. We are hoping to hear back from developers who has some time to spare (especially this coming Monday). We understand this is short notice. If you have the time to spare this MONDAY, MAY 12 and/or the next MONDAY, MAY 19 - please email team.london(a)opentechschool.org. WE’D LOVE TO HEAR FROM YOU! Best, Gen Ashley Co-Organiser, OpenTechSchool London What is OpenTechSchool? ----------------------- OpenTechSchool London (http://www.meetup.com/opentechschool-london [1]) is a community initiative offering free programming workshops and meetups to technology enthusiasts of all genders, backgrounds, and experience levels. It supports volunteer coaches in setting up events by taking care of the organizational details. OTS’ main goal is to create a friendly learning environment where no one feels shy about asking any question. Everyone is invited to participate, whether as a coach or a learner. The range of free courses offered can range from HTML/CCS/JavaScript to Python, Ruby, GIT, Mobile development and others. As these are “coaching” classes, rather than a “teaching” class, it’s a more relaxed environment for both learners and coaches, as there is no teacher in front, but coaches are around to help learners, if they hit difficulty, as they go through the learning materials (already prepared). Please see http://www.meetup.com/opentechschool-london [1] to see photos from previous coaching classes.
