Google Maps’ Moat, by Justin O’Beirne. On the competitive advantage that Google Maps has over Apple Maps – equally interesting for map nerds and business people.
Saturday occupation: eating spicy cheese made of cow milk and paprika.
Mars soundtrack (the National Geographic tv-show) is fantastic. Nick Cave is just the perfect voice to convey that feeling of exploration and fear. Moon, Interstellar, The Martian, etc; it seems sci-fi movies got an appreciation for soundtracks that have a major role in the film – and I enjoy that.
As much as I like Cave’s main theme for Mars, after a few episodes, I was in the need of something like Dylan’s Shelter from the Storm. Exploration needs joy and celebration.
Running in Circles is Basecamp’s view of agile product management. They acknowledge the value of working in cycles, but add three pieces: having the time to focus, being able to modify the original plan, and tackle the core unknowns of the feature first.
The first two are enablers that are provided to the makers by management. The last part is how the maker make the most of those powers. Together, they form a process that is nicely captured with the uphill / downhill metaphor. Uphill you are discovering the unknowns and making decisions about what goes in, downhill everything is clear and you are implementing it at warp factor 10:
I came across Module Counts, which tracks the number of published modules for major language package managers. At this point, npm has 600k packages published, which is 3 to 4 times what any other package manager has. I’m not aware of download statistic across different package managers, but npm has surpassed the 2 billions downloads a week mark.
This puts me in the perfect mood before going for a walk in this sunny and cold Saturday.
Software architecture failing: tech writing is biased towards what the big ones do, which usually doesn’t fit most other contexts – but, who got fired for choosing IBM, right? Although I feel connected to this rant at an emotional level, I do think it’s necessary to elaborate more and make a positive contribution: help to create and spread that alternate history of software development. How do you do it? Hat tip: Fran.
On November 2016 I had a free month between jobs. Apart from some resting, reading, and general preparations for my new adventure, I still had quite a bit of free time to do new things or build good habits. It was while cleaning my office that I found a keyboard I had bought a couple of years back:
Its layout was a beautiful matrix -which is good for your fingers- and came with Dvorak by default. So it struck me: how about improving my typing during the coming weeks?
As a programmer, typing is an essential skill for me. I had been doing it for more than 15 years in a learn-by-doing way, and I plan to keep typing for years to come. I thought it would be fun to spend a couple of hours a day training in touch-typing and give Dvorak a second try. And so I did.
Before I switched, I recorded about 15 typing sessions at TypeRacer using the QWERTY layout, which logs typing speed (words per minute) and accuracy (% characters right over the total). I was at 67 wpm and about 95% accuracy at the time.
Progress was very humbling at the beginning; it felt like learning to walk again, and I swear that, sometimes, I could even hear my brain circuits being reconfigured! After a few weeks, though, I was under 40 wpm and, by the end of the month, I was under 50 wpm. I stopped quantifying myself by then: as I started working, I had a lot of typing to do anyway.
During the first months, the only moments I struggled and felt like perhaps the switch wasn’t a good idea after all was during real-time communication: chats, slack, etc. I don’t know what people thought of me, but my velocity at the time was typing-bounded – I was certainly a very slow touch-typist by my own standards.
But time passed and I improved.
Spáñish Dvorak and symbols
Throughout the process I changed my setup quite a bit: I started my journey using the Programmer Dvorak layout with a TypeMatrix keyboard. After a few months, I switched back to my good old ThinkPad keyboard because having to use a mouse again after years not using it was a pain. A few months later, I switched to the Dvorak international, because the Programmers Dvorak layout didn’t quite suit me. Then, I tweaked the common symbols I use for programming so they were better positioned. Besides, although the bulk of my typing is in English, I still need to write decent Spáñish, which basically means using tildes on vowels and ñ. TLDR: the Spanish Dvorak version made things more difficult, so I’ve just tweaked the Dvorak international to accommodate tildes and ñ as I see fit.
At this point, I believe I can patent my own layout:
All the changes I did to the symbol positions have affected my ability to build muscle memory for them – sometimes I still need to look at some specific symbol on the keyboard. However, the current version has been unchanged for months, so I only need a bit more time for them to stick.
Given that I was a QWERTY user for 15 years, I thought I would give the new layout a year before comparing any statistics. The fair thing to do would be comparing after 15 years, but I’m a bit impatient for that. I went to TypeRacer again and noted down the results for about 20 races. These are the numbers of this totally unscientific experiment:
A few remarks:
- In terms of speed, it seems that I’m mostly there. My median speed now is 65 wpm, 2 words per minute less than before. I had a higher peak (83 vs 79) in one of the current typing sessions, but I was under 60wpm in more sessions this time.
- In terms of accuracy, I’ve improved a bit. My median accuracy has increased by 1,5 points, and I had only 2 sessions below 95% of accuracy this time.
Overall, I’m very happy with the switch to Dvorak. My accuracy has improved, meaning that I can maintain a longer typing rhythm. Not having to correct mistakes makes me a faster typist as well, and by learning to touch-type I also have grown more endurance.
This experiment was very humbling but fun. I believe it increased my brain plasticity by an order of magnitude, and I’m hoping to improve my numbers as years pass as well. However that turns out, though, I think of this as a gift to the elder me, a way to prevent typing pain in the future and promote a healthy use of the tools I heavily depend upon.
