Will, author of Reasoned Schemer, having coffee sadly, this is the most flattering shot of hime in the collection. The spirited Salt Lake City hacker, whose infectious enthusiasm warmed many conversations was a kind soul and a C64 alumnus. Since then, I’ve bought his book, read half of it, perhaps. It’s mind-bending and kind at the same time. Progress must be slow, as I’m doing this on my own.
adr-tools is a set of command-line tools by Nat Pryce that allows people in software projects to record their design decisions, as they go along, a bit like the captain’s log on the Enterprise. (Much more on such log entries at this wiki for trekkers.) You type adr new Use Postgres, and it creates a formatted Markdown file, with headings in place, ready for you to fill out, fleshing out your reasoning for the decision.
That library, I had the good fortune to be able to make a Homebrew package (a tap, in the parlance) for it, making installation of the tool a one-liner. This is such a package: homebrew-adr-tools. That’s all there’s to it, just a homebrew-prefixed GitHub repository with that file in it.
InDesign’s Data Merge feature is great. This is a video I return to, when I need to use it.
There is a catch, though: the data must be in the right format for this to work with Swedish text, which has å, ä and ö.
Use a spreadsheet app to make a dataset (columns and rows)
Use column names without spaces, and only lower-case characters. Do not use any “special characters”. So: only between a-z.
Export it to CSV format
Open the Terminal app in your Mac
Change to your directory where the file is by dragging its folder into the Terminal window and hit ENTER. Perhaps you need the command cd followed by a space and then drag the folder. (Tip from commenter Dima. Thanks!)
Type the following text command and press ENTER to change the file filen.csv to the target format (which is called utf-16):
iconv -f utf-8 -t utf-16 < filen.csv > filen2.csv
A new file filen2.csv is created in the same directory.
Use this new file in your InDesign data merge!
Typing man iconv will bring up a text manual for the iconv command. Try it! (Quit the manual by typing q.)
the < and > are “output redirection” symbols, used in two directions in this so-called pipeline
The manual taught us that the command can be expressed as:
You’re desperate. Your legacy code-generation code outputs a Hash using hash#to_s. You’ve flouted many Rubocop rules to get to where you are. Suddenly, it gets too much. You search the Web for a pretty-print function that you want: a Rubocop-friendly Hash pretty-printer.
Empty-handed, you cough up blood, while a police car’s red-blue lights flicker in through the blinds of your run-down office.
With tired fingers, you type out something like:
Then, you faint, blessed sleep converges on you and envelopes you in a colorless void.
I finished reading a novel. Been a long slog. Five years to read a novel? Some blogger said they immediately began re-reading it, to see and experience the rich intertextuality etc. Thanks, Evan, for the reminder that it’s been so long. PS: the book was grand.
The club format is the same every time: first an hour of social or at-your-computer time. Then an hour of show-and-tell explanations, demoing and showing stuff.
Emil showed us CSS and SVG techniques, some of them brilliant. SVG is a deep well to drink from. Read more at Sara Soueidan’s website.
Pelle made a very nice hands-on demo of a system of services he’s built, which involved commenting on any page using his telephone.
We had talked about Node.js a fair bit, and I showed what the private caching npm server sinopia looks like when installed. Its claim to fame is its file-based caching – don’t fetch packages from the central repository more than you need.
When I had showed that, we had used up our time, and it was time to put the crisps down and go home. How kind, to have time limit, so that people on tight schedules won’t miss stuff.
On the way out, I asked: “Pelle, do you have a exercise for me to take home?” He responded immediately: “Make your site receive or send WebMentions.”
Run relevant code-checking tools on your code, before it is even checked in locally. Using the Ruby project Overcommit, you can set this up on your own machine in a jiffy. Or, read more about git hooks.
I took these steps:
Install the overcommit gem in your active Ruby. gem i overcommit
Install overcommit in your system Ruby, using this neat trick:PATH=/usr/bin:/bin:/usr/sbin:/sbin sudo gem install overcommit – This makes it available to tools like SourceTree! (On committing, it opens a bare shell, without your cool settings.)
In your project directory, where you wish to begin using Overcommit to run Git hooks: overcommit --init
Configure the resulting .overcommit.yml to enable/disable the checks you want run.
Yesterday morning, the ISS was resupplied, in a textbook example of a great space-station docking. I had just woken up, and saw the last 2 minute of the docking. Very exciting. Then I began trying to finish this conference overview. It’s more stream-of-consciousness than report. You’ve been warned.
So, outside the bubble of conference again. My tweeting will be less frequent. The friendly #polyconf hashtag has lots of tweets. The weather will be less scorching.
The place: Poznan is getting better and better every time. Weather, shopping, eating.
People, a very small sample:
Felix and Karolina. My people. Conferences are meeting points, folded in spacetime, so that when you meet again, it’s as if no time has passed. (Terms and Conditions apply.) Cheers, you magical unicorns.
Robert Virding. Gave me a short personal Get Started tutorial with LFE (in Swedish) after we’d lunched, and ruminated on How Much We Got Right when defining the core principles of Erlang (when he was designing the language). A generous, thinking, caring community member.
Virding runs the LFE – Lisp-Flavored Erlang – project. So, the small community of people using Erlang, cut to a smaller piece by removing anyone who wouldn’t use Lisp – those people must love this language. And I believe they do. Being confident about your choices and tradeoffs, is a wonderful thing.
(There are more little on-top-of the Erlang-VM languages. Some of them even go outside the Erlang semantics, against the grain. Luerl, for one. Wow, I didn’t realise that was his project, too. And Erlog, too. Wow.)
Alban & Julien. On the evening of the last day, we got to talking about films. The two Frenchmen with their real French accents, me with my Cahiers du Cinéma fake accent. Tips of movies to watch: Raise the red lantern, Still the waters, Departures, and The Saddest Music In The World. We talked of Jodorowsky, Virginie Despentes and Gaspard Noé. How some films make you angry.
Stefan Karpinski. A friendly programming languages person who could speak Swedish. Also part of making Julia. A pierogi-eater. Much exciting is going on with the Julia language, which is a quite modern way to write fast programs. It was interesting to hear about the formation of the Julia company. Heady times.
Brendon McLean. A pierogi-eater. Great story-teller with a big heart. His work involves some scientific computing. He made a show-and-tell of his S-expression-based communications channel between Ruby and Python, by way of IPython Notebooks. Very grounded, calm in his presentation, but a very lively and present human being in conversation.
“My four-finger swipe isn’t so good with this thing on my finger.”
Brendon lives in beautiful Cape Town, where he sits in front of a computer all day.
Alex P. A pierogi-eater and monoid monger. Fine Clojure talk on timeseries work.
Pierre-Yves Ritschard. A pierogi-eater and maker of cluster management software around Mesos. Programmatic access to the cluster made easier using Clojure. “mesos interaction in idiomatic Clojure” as the repository succinctly states. Great slogan: mesomatic: the cluster is a library.
Amir Chaudhry. Not a confirmed pierogi-eater. MirageOS’er who introduced that ecology of tools. Slides from his talk can probably tell you some of the story. We had friends in common, and said hello over the ether to them.
The very pleasant and generous miniKanren evangelist William E Byrd: a home computer hacker. We talked of the Commodore 64 and of the 1541 (William described with disgust the design failures of that drive; read the details in the wiki article). He also shared insight on racing the beam programming in the Atari 2600. And, his 3-hour miniKanren tutorial was just stellar. The people in the room got the hang of the lingo, the thinking, the machinery, just by following along Will’s session. Quite a feat.
I guess I now need to put the Reasoned Schemer onto my book list.
Conference apps must be offline Web apps. No more fiddly App Store have-to-update-app-to-update-schedule. Hoodie could be used to kick off that Web app.
