IIRC SQLite originated as a Tcl extension. In Tcl at the user level "everything is a string" or a number. So it's logical SQLite would accept values as a string or number. Interestingly a Tcl function defines its own semantic

Thanks for the hint! Didn't know about zellij, but indeed looks very interesting. Downloaded and will try it out.

I was having similar thoughts about building UIs back in the late 90s and a few years thereafter. There were a number of tools, I remember using Tcl/Tk to create a GUI scheduling program that was relied on for many years. Later on we h

Of course many, even most, painters do sketch what they intend to paint, likely that's the predominant technique. But it's not universally true, particularly among artists working in the last 100 years or so. Certainly Jackson Pol

AFAIK the answer is an emphatic yes, a lot has changed since 2005. Tcl9 was recently released and has many new features. As far as Tk goes, for a number of years we've had "themed Tk" or Ttk widgets, much better styling, rese

Yes indeed, I concur completely with your comments. I've used Tcl/Tk for a few decades and for a long time enjoyed it's Lisp-like character. Of all GUI toolkits Tk is by far the best thought out, no wonder it's been adop

Probably not what most on HN would think of, but for writing a simple app with a GUI, I'd suggest that Tcl/Tk is hard to beat. Of course the simple approach wouldn't suffice if the program had to be compiled to a native binar

Though I haven't endured the "spinning" as described in the OP, I do appreciate how the "shape" of text promotes or inhibits comprehending it. While programming in C isn't especially difficult for me, writing&#

Chicken indeed interoperates with C quite easily and productively. You're right that the generated C code is mostly incomprehensible to humans, but compiles without difficulty. The Chicken C API has functions/macros that return va

Perhaps a bit tangential to the main topic, but it is of course true that UTIs can adversely affect cognition in the elderly, even precipitate delirium, etc., depending on type and severity of infection. Naturally that also occurs with othe

Sure, the FSF is as idealistic as it has been influential. Can't fault FSF for unrelenting commitment to stated purposes. While the totally free OS was a goal that never quite materialized, a large proportion of modern open-source syst

This topic provokes a question, what exactly is "winning" anyway? As others point out, how could there be absolute winning, or complete dominance of the whole gamut of software used for every purpose. Of course, no one ever propos

It is indeed a win. It's long been established that for obese individuals even 5% weight loss reduces comorbidity of obesity-related conditions. Of course greater weight loss, 10-15%, gives better outcomes. Typically the difficulty is

Absolutely. Years ago writing programs for *BSD/Linux, PS was the natural, most direct way to implement printing to printers equipped with a PS interpreter. Fortunately the PS language was very well documented. That made writing PS pre

Well, Tcl is kind of a mixture of scope rules. In some respects, e.g., within a proc, it's mainly a lexical environment, but of course dynamic scoping is introduced by commands like upvar/uplevel. FWIW Tcl programmers don't c

Well, there's a (modest) learning curve involved in customizing color schemes and of course more complex tasks that are still in the domain of user's options. Users can be fearful of "messing it up" if they change defaul

I concur that TclTk is enormously versatile and productive. I've always regarded Tcl as a Lisp-like language. Tcl and Lisp share characteristics like homoiconicity that enable benefits you describe. Tcl isn't as widely known and

Indeed so. Printing on paper and other substrates is inherently subtractive in nature which limits the gamut of colors and values that can be reproduced. Digital methods make the job of translating additive to subtractive media easier vs. t
