Dark Mode

Nutrition wise, scientists always agreed that eggs contained pretty much everything the body needs. Problem was cholesterol which the egg does significant rise. 

The fact that did change was that high cholesterol is bad, some doctors would argue even deadly for ones health. Problem was that this fact was based on a research that was on a very small group of subjects and if I am not mistaken it was not even humans it was lab rats. 

The problem none really funded a serious research for this fact and when they did they discovered that indeed eggs and other food do raise cholesterol significantly but our liver is capable of reducing the production of cholesterol to compensate hence its nowhere near as harmful as they used to assume. 

Science is flawed mainly because finding small facts is easy and cheap but general fact are very complex and very very expensive. 

Like all things, you get what you are paying for. This is why you see and hear so many contradictory facts. They are mostly based on simple cheap research. Plus "fact" is purely a fantasy, our world is too complex for facts as most people define them. There is truth sure, but not as easy to consume and explain as we would wish. 

The preference to light and dark themes is not product of bad scientific research. I suspect the reasons are too complex for science anyway because we are even eons away from explaining the human brain and how it works. 

Pharo not only allow you to choose a theme but its theme classes are actually very easy to use which is something it inherit from Squeak. It took me a day to create my own theme. 

The Dark UI theme class is excellent example for anyone who wants to subclass it and create his own light or dark theme because its not that complex.

I have observed similar circles in background color usability. Pharo has ability to choose a theme, it has both currently fashionable and older ones to choose from. I do not see need for anything else on that front.

Ups… I think this FIT file format is for something else…

Or you people can just dim your screen instead of staring into a 60W lightbulb... then the theme doesn't matter.

Actually what you say makes no sense to me because my monitor is already at bare minimum. Its not the intensity, its the contrast. The problem obviously is not an exposure of 30 minutes. The mail I am writing now  has a white background. But its not a problem because I spent an 1 hour tops with email total time. I would like if Gmail had a dark theme but its no big deal.  However when one spent more than 8 hours it becomes a problem. 

It was the same when I was studying in UK law. I was very used into reading english because the vast majority of the coding books I had bought and reading since I was 13 years old were in english. It was not a problem reading for an hour, but after 5 hours both my eyes and brain were tired. Its that extra effort that accumulates hour by hour and the more time you spent, the more obvious it becomes. 5 hours reading a book in my mother tongue is like night and day. 

So  when I was spending a lot of hours working with Pharo the white them did became a major problem for me. Its not as if I see a light theme and after a few minutes I scream in pain "Oh my eyes are burning" :D

I completely agree - dark mode is great for content that you want to
look cool, but no one consumes. :-)

You assume wrong cause dark themes have been dominating GUIs for over 3 decades now.

Not really; bright on dark was only dominant in the days of the CRT terminal when there were no "themes".  (Even if you could do it as a hardware switch, setting, say, a VT220 to black-on-white both looked terrible as it was more an uneven gray, and tended to dim  the tube more quickly by burning in the background.)

Instead, since full bitmap graphics happened, all screen interfaces back to Xerox's prototype office systems, then Lisa/Macintosh, and then Windows 2.1 have been using dark type on a white background for text work.  Partly this was because of the original office metaphor, but partly also because it was shown that it was easier (meaning, less error prone) to read.  

Here's a study that showed that participants were 26% more accurate in reading text that way (note that "contrast reversal" on displays in those days meant dark characters on white background):

Bauer, D., & Cavonius, C., R. (1980). Improving the legibility of visual display units through contrast reversal.
In E. Grandjean, E. Vigliani (Eds.),  Ergonomic Aspects of Visual Display Terminals (pp. 137-142).
London: Taylor & Francis

There were other studies in the 1980s that didn't report lower errors but instead faster reading with black on white. Academically, the matter's pretty much considered settled - black on white is better for most of the population, and that's on screen, not on paper. (You can substitute any degree of light or creamy for the white, that's really a variation of screen quality.)

The engineering workstations of the late 80s and 90s (Sun etc) used black and white as the application default as well, with white on black limited to console/shell windows. This was partly for consistency with the old style, partly for easy contrast with application windows in a multi-window environment.

Pharo was the rare exception of using a white theme. Light themes may be popular but white are definitely not.  The web is the last fort of bright themes, but the web was and still is eons behind when it comes to matters of UI.

Most other Smalltalks are dark-on-light by default all the way back to Smalltalk-80 out of Xerox PARC.  None of this had anything to do with the Web, which came after, but which obviously also profits from the same increase in readability.  Rather than behind, Smalltalk was ahead and the rest of the world followed.

The dark theme as default in Pharo I personally consider a step back. As someone who's been busy for 25+ years defending use of Smalltalk for real applications, a return to a primarily developer-cool presentation instead of a user-oriented default is IMO not a plus for a language branch that was billed as more industry-oriented (which IMO is not exactly the same as developer-oriented).  But I also understand the desire to attract developers with the look that's currently fashionable.

That said, I wonder if the recent preference for dark among developers (not Pharo-specific, but many languages) has to do with the rise of widespread code highlighting. I could see how colour highlighting shows up better on a dark background than being glared over by a white one.
