I've long regarded the great variety of chilis as its own distinct food group. But wonderful as they are for flavoring food, quite often in my home, I'm not sure how much of an effect orally consumed capsaicin has on memory functioning.

Conceivably parenteral capsaicin has different effects on hippocampal integrity or physiology than achievable with ingestion. I'm not familiar enough with disposition of capsaicin in the gut to comment further. My question is whether capsaicin passes from gut into the circulation in any appreciable quantity. I suspect it doesn't but I couldn't say I know for sure. I'll have to add it to the already long list of things I need to look up.

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, resembles native widgets quite closely. Ttk widgets aren't as configurable as regular ones, well, everything has tradeoffs.

You should take a look at the current releases, you might be pleasantly surprised.

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 adopted by a number of other languages.

Tcl does have a few disadvantages, for one the lack of distinction between string and list types makes certain programs hard to write. Also the absence of lexical environment for the apply command requires awkward workarounds. Many Tcl users dislike expr syntax.

Warts notwithstanding, Tcl has allowed me to be very productive. Over the years it's been steadily improved, and yet remains mostly compatible with code written even decades ago. That's a rare accomplishment in the programming universe.

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 binary. Though Tcl/Tk has an excellent C API, so a binary version of the app could be built if considerably more work to accomplish.

A very good response to the parent comment and summary of the current situation.

AIUI the Iranian attack on Arab countries is strategic, increasing energy costs pressures the US to stop military action. However the US and allies were prepared with set aside oil reserves, increasing supplies from other sources, and reducing Iran's ability to interfere with shipping.

Major warfare always has tragic effects, but against regimes actively pursuing destruction of other nations, return of fire is a rational response.
