Work Sample Tests: Bring Your Own Code
If you’re hiring engineers, some candidates will already have code they can share: side projects, open source, and so on. It’s silly to ask those candidates to write new code just for your interview if they already have code they can share. So, if you’re asking candidates to code as a work sample test, you should also offer to let candidates submit something they’ve previously written. Here’s how. -

Work Sample Tests: Pair Programming
Coding homework is my default work sample test: I use it for all engineering roles unless it’s obvious that another kind of exercise is better. There are good reasons to make homework-style work sample tests the default: they’re relatively easy to construct, they scale reasonably well to large hiring rounds, they’re accurate simulations of real work, and easier than most other kinds of tests to construct in a way that maximizes inclusivity. Here’s how to conduct a coding homework work sample test. -

How Django Got Its Name
Pictured: From left to right, musicians Sebastian Peszko, Francisco Batista, and Filippo Dall'Asta in Berlin, Germany. In early November, my husband and I celebrated a friend’s birthday with dinner and a show. The birthday boy has eclectic tastes and it’s always a treat to be included in his plans. Little did I know, however, that our night out in Berlin, Germany, would be related to my day job with Caktus, which is of course, based in Durham, North Carolina ... As a side note, I’ve been working remotely from Berlin since August 2021. Our group showed up at 800A Bar & Cabaret a bit late, so the music had already started. Onstage were guitarists Filippo Dall'Asta and Francisco Batista, plus Sebastian Peszko on the viola. The music seemed familiar but I couldn’t quite place it until my husband realized it was similar to the original theme from the TV show “Monk”! The musicians were incredibly talented and we had a very enjoyable evening listening to them as well as the jam session later featuring various local artists. Though I was unfamiliar with this style of music, I was familiar with the name Django Reinhardt as I had read a little … -

PyGrunn: setting up new developers for success - Marijke Luttekes
(One of my summaries of a talk at the 2021 10th Dutch PyGrunn one-day python conference). Get your house in order first. Before you can start training people, you need to have an onboarding strategy in place. Make sure you've got that beforehand. You also need your communication tools to be ready. Oh, and documentation is important! It is good in general, but there's a specific advantage during onboarding: if you've got it, new developers get an opportunity to be more independent and to look things up for themselves Let us get started guiding new devs. Psychological safety is important: you need to feel safe. Safe to talk about mistakes, safe to make suggestions. If you're the senior: keep in mind your position of power. If you say something, a junior developer might think it is The Law. What you don't want: a clone of yourself! It is good for a company to have diversity. Bring the new developer with you to meetings. And let them speak! (So try to shut up a bit yourself). Success is a team effort - and so is failure. New developers need feedback. Compliment in public, negative feedback in private. Oh, and make an … -
PyGrunn: live blogging with wagtail - Coen van der Kamp
(One of my summaries of a talk at the 2021 10th Dutch PyGrunn one-day python conference). Wagtail (https://wagtail.io/) is a nice CMS layer on top of django and python. Wagtail is special in that it doesn't have a build-in user-facing front end. You are invited to build your own that perfectly suits your needs. Wagtail is opinionated in that sense. It does have a nice admin interface for adding content. Through google summer of code, an earlier idea he had on live blogging was added to wagtail. It is intended for live blogging a sports match, for instance. Lots of small messages. It can grab input from slack or telegram. Of course, you can also use the admin interface or a REST api. There is a bit of a workflow mechanism. You perhaps want to format the first line of an incoming message as a title. There are multiple ways to set up the blog-viewing webpage. Interval polling, long polling, websockets. Websockets are the best option, but it takes more setup effort. Interval polling is the easiest option: just plain http. https://wagtaillive.fourdigits.nl/pygrunn/ is where they do some test live blogging of this conference. The project lives at https://github.com/wagtail/wagtail-live -
PyGrunn: large scale python satellite image processing - Ivor Bosloper
(One of my summaries of a talk at the 2021 10th Dutch PyGrunn one-day python conference). Satellites. There are almost 3000 satellites orbiting the earth. Some of them have cameras, which are the interesting ones for him. He started Dacom (now CropX), agricultural software. Satellite imagery is interesting for farmers as you can see how well the crops are growing by analyzing the images. He did a live demo. They have a website with all 800.000 fields in the Netherlands. For every field they have image data. They can show it both as a regular image, but also color-coded for amount of greenery. And of course a nice graph throughout the year. You can do all sorts of analysis on it. Look at the variation in crop yields within the field, for instance. You might have to use more fertilizer in the low-yield areas. But you also have to use other data sources, like an elevation map. They started out experimentally with groenmonitor.nl in 2014. In 2015, ESA launched the "Sentinel 2a" satellite (with a twin, "2b", in 2017). The data is free, part of the EU Copernicus project! They started using the data in 2016. The images are huge … -
PyGrunn: don't trust your coverage report - Olga Sentemova
(One of my summaries of a talk at the 2021 10th Dutch PyGrunn one-day python conference). How do we know if our code works? Perhaps the requirements you were given were unclear. Perhaps there simply is an error in your code. Perhaps your software is used in the wrong way. There are many sorts of tests. The one she focuses on is unit tests, the one we have the most influence on as programmers. You can use a traceability matrix where you put every individual part of the requirements ("division by zero results in an error") in columns. In the rows you mention the tests that verify the specific requirement. Lots of work, perhaps only needed for medical equipment. You're also restrained by the (in)completeness of the requirements. And it is a manual process... You can also use coverage.py, which checks how many lines of your code are covered/executed by your tests. When you run coverage, you should configure it properly, so that it only reports your python files. You don't want to include the standard library or an external library in your report. Also exclude your test files from the report, as they normally have 100% test coverage and …
