When Homebrew breaks your Python virtual environment

Ever had your old, trusty Python virtual environment fail on you? I sure did. Sometimes, when I activate or switch between virtual environments, I get the following error: $ workon eve dyld: Library not loaded: @executable_path/../.Python I never really took the time to look into it. When this happens, because I am in a rush (and because I am a lazy old fart), I shrug it off, recreate the virtual environment on the spot, and get back to work. ...

Book Review: The Water Dancer

The Water Dancer is the debut novel for Ta-Nehisi Coates, an author and journalist best known for his nonfiction works. Set in a slave plantation located in pre-civil war Virginia, this is a bold and ambitious story about slavery. From the editor website: Young Hiram Walker was born into bondage. When his mother was sold away, Hiram was robbed of all memory of her—but was gifted with a mysterious power. Years later, when Hiram almost drowns in a river, that same power saves his life. This brush with death births an urgency in Hiram and a daring scheme: to escape from the only home he’s ever known. ...

Strong opinions on software development

After six years in the field, Chris has shared his strong opinions on software development practices, languages, and methodologies. I like his attitude. Willingness to continuously put one’s personal views under scrutiny, eventually adapting or even changing them as needed, is not a common trait. Not in our field. While I generally agree with most of his opinions, I feel the urge to comment on a few of them. Typed languages are better when you’re working on a team of people with various experience levels ...

The Great Unbundling according to Benedict Evans

As a non-native English reader, I had to look up the true meaning of “Unbundling” as a neologism. According to Wikipedia Unbundling is a neologism to describe how the ubiquity of mobile devices, Internet connectivity, consumer web technologies, social media and information access in the 21st century is affecting older institutions (education, broadcasting, newspapers, games, shopping, etc.) by “break[ing] up the packages they once offered (possibly even for free), providing particular parts of them at a scale and cost unmatchable by the old order.” Unbundling has been called “the great disruptor.” ...

Upcoming speaking engagements, with ramblings

I am presenting at two different events in February next month. Given the current COVID situation, that is entirely unexpected. In 2020 I only gave four talks, three of which were virtual. I am not holding my breath for 2021. Conferences are going virtual all year-long. Next year too, most likely. There are some clear advantages in going virtual, but the final result is a net negative. Any conference junkie will tell you that she/he attends for the people first, and only then for the sessions themselves. At these events, the most exciting stuff happens in the corridors, usually during breaks. A little story here. You might know that I run a motorcycle club. Well, the very idea of founding it was actually ignited by a corridor chat, few minutes after I delivered a session. Replicating this kind of in-person interaction online is, well, next to impossible. ...

The unreasonable effectiveness of simple HTML

We’ve seen other articles pointing the finger at unnecessarily bloated websites. Terence Eden’s On the unreasonable effectiveness of simple HTML deserves mention, I think, for two reasons. First, the delivery is incredibly effective. Second, it is effective because of the storytelling. By enveloping the message into an original short, touching story, he achieves two goals. First, he captures the reader’s attention; second, he makes the experience memorable. Please, go and read it; I’ll wait here. ...

On the short, tormented life of Phil Katz

Bless the Internet Archive and its Wayback Machine. With it, we can go back in time and read The short, tormented life of computer genius Phil Katz, an unusually detailed and accurate article published in the April 14, 2000 issue of the Milwaukee Journal Sentinel. When he was found dead April 14, Phil Katz was slumped against a nightstand in a south side hotel, cradling an empty bottle of peppermint schnapps. The genius who built a multimillion-dollar software company known worldwide for its pioneering “zip” files had died of acute pancreatic bleeding caused by chronic alcoholism. He was alone, estranged long ago from his family and a virtual stranger to employees of his own company, PKWare Inc. He was 37. ...

Book Review: Erebus, The Story of a Ship

I finished reading Erebus: The Story of a Ship by Michael Palin, an excellent book on the dramatic adventures of the HMS Erebus with her sister ship, the HMS Terror, first in James Clark Ross’s Antarctic expedition of 1839-43, and then during Franklin’s ill-fated Arctic expedition in search of the Northwest Passage. I knew Michael Palin as a member of the Monty Python comedy group. As it turns out, since 1980, he has also made many travel documentaries and books. ...

Five Good Books I Read in 2020

Here are five books I read in 2020 that I would recommend. I read several fine books last year, so please check out my reading history if you are unsatisfied with this selection. Mani: Travels in the Southern Peloponnese, by Patrick Leigh Fermor. I love Patrick Leigh Fermor. Over the years, I read almost everything he wrote. He has been described as “a cross between Indiana Jones, James Bond, and Graham Greene,” and for a good reason. He bridges the genres of adventure story, travel writing, and memoir to reveal an ancient world living alongside the twentieth century. Here he carries the reader with him on his journeys among the Greeks of the mountains, exploring their history and time-honored lore. The Mani, at the tip of Greece’s-and Europe’s-southernmost peninsula, is one of the most isolated regions of the world. Cut off from the rest of the country by the high range of the Taygetus and hemmed in by the Aegean and Ionian seas, it is a land where the past is still very much a part of its people’s daily lives. ...

HttpResponseMessage.Content is non-nullable in NET5

Today I was happily migrating some C# projects to Net 5 when I stumbled upon something unexpected. My focus was on a library (a NetStandard2.0 REST API client, an SDK) and its associated test suite. The test project was a NetCore 3.1 application. As you can imagine, being a REST API client, the library does a lot of talking with a remote Web Service. It does that by leveraging the almightly System.Net.HttpClient. The library has a private, static HttpResponseMessage parser method. Its job is, well, to parse all responses from the remote. It looks for known, expected headers, gracefully handle them, and then deserializes the response content, if there is any. ...
