I used Datomic for a few years at a job. In addition to the cost and proprietary nature, I'd say there are two reasons; 1) New and different things come with risk, and many folks are risk averse, especially in groups 2) More concretely

Repeated patterns in digital signals can cause errors in several ways such as DC bias (likely the case here), or a buildup of energy on the edges of the signal's fourier spectrum which then gets filtered out and shows up as signal degr

A report in The Globe and Mail indicated that the buyer was re-imbursed for most of the purchase cost. So very likely Sotheby's insurance provider is ultimately on the hook. https://www.theglobeandmail.com/politics&#x2

Michael Lewis' book "The Fifth Risk" has other stories of exceptional public servants, and a very insightful commentary on public service in general. https://en.wikipedia.org/wiki/The_Fifth_Risk

First off, thanks! This does look like a fun way to learn things. Secondly, FWIW, when I read the the term 'excercises' in the HN title I interpreted that to mean exactly a learning tool and not interview prep. The term "Ch

For sure, you can if you want to. And if you pull it off there are some advantages, which the article describes. It's just harder.

And radio! We use lots of radio as well. I wonder what the longest information carrying electric wire is? They used to cross oceans, but not anymore. There are loads of DSL twisted pairs and co-ax cables in the "last mile" that

ly5: The universe is made of two kinds of particles, Bosons and Fermions. Light is a boson. Most of the stuff we touch is made of Fermions. Electricity is fermions also. Bosons, like light, don't like to interact with things. They j

A wise person once said "Bosons are for transport and fermions are for switching."

It violates the principle of Least Surprise; if I'm invoking run0 I'm expecting it to run my program with a different UID and return the same stdout I'd have gotten if I had just run the program in my shell. Not inject a who

Denis Villeneuve is another example of a universally loved director, and he is not often criticized for obvious compromises. Villeneuve's good friend Christopher Nolan presents as a bit more of a prickly pear, but he has a very long li

My father was a PhD psychologist and family therapist. He was on the witness stand during a custody case explaining a theory of personality when the cross-examining lawyer said scornfully "I'll bet you got that out of some book.&

While all those pointing out that 8GB of RAM was mainframe stuff in the 90's are absolutely correct, I would offer that the software bloat between 90's software and modern software does make the _experience_ roughly comparable. Ex

I certainly think so. Or at least I find it very helpful to think about interface design that way. It's DLS's all the way down.

Er, git-svn is bi-directional? Targeted at allowing a developer to have a local git workflow that syncs up nicely with a central svn server? Is that the svn-git you're after?

Git-svn is very mature and feature rich. I've used it a couple of times to good effect. Little need for it these days though. https://git-scm.com/docs/git-svn

I read somewhere that "in the 40's and 50's they built computers for the computation, but it turned out the storage was almost more important. Now we built AI for the cognition, but it will turn out that the patience is almos

The pipettes I worked with in school 30 years ago were effectively glass straws with a mark for the designated volume. One dipped it in the solution over the mark, used the thumb to seal it, and then carefully let tiny amounts of air in to

Thanks! My daughter works with pipettes all day long, and this is fascinating. One of her favorite aphorisms is "Don't lick the science!" and today I learned that apparently we used to lick the science.

Now I have a funny vision in my head of a WWII radio tech standing in a field, wearing an absurdly large RADAR rig, with a big sweeping antenna protruding from a backpack and a massive screen on his chest, turning this way and that, all con

Your grammar and style are great. This isn't a novel, it's highly technical material about concepts that are difficult, very detailed, and unfamiliar to most readers. It's okay if people have to re-read stuff.

Only to an extent. I can't think of a language environment where each package can have its own version of a dependency. Python certainly isn't one. So if you want any of the Flask 3.0 features you have to take the new Werkzeug,

When I explain database indexing to new folks I start with a mini-lecture on card catalogs, complete with images. Even young folks who never saw one can _very_ quickly understand what it's for and how it works. And then when you poin

Every format for 'human readable configuration' is on a slippery slope to becoming a secret programming language. "You know what would be great? A conditional statement of some kind. That would be super handy."
