Samsung C27F390FHU Zwart – Kenmerken – Tweakers

Posted by jpluimers on 2018/09/25

Bumped into a place where the only external monitor was a [WayBack] Samsung C27F390FHU Zwart – Kenmerken – Tweakers

Dislike because:

  • only 1920×1080 at 27 inch
  • only HDMI and analog inputs
  • cannot adjust height, so as a dual screen with a 15 inch MacBook it is meh
  • the curve distorts horizontal lines in a way your eyes will not compensate for

Images from [WayBackSamsung C27F390 27-Inch Curved LED Monitor – HDMI, VGA: Amazon.co.uk: Computers & Accessories below the fold.

Higher resolutions – not just 4K – have been readily available since before this monitor was introduced march 2016 [WayBack] Samsung unveils new CF591 and CF390 curved monitors

How not to structure your database-backed web applications: a study of performance bugs in the wild | the morning paper

Posted by jpluimers on 2018/09/25

This is about Ruby anti-patterns, which is a good step to start investigating the own anti-patterns you use in your own development environment:

If you have trouble getting an screen mirror from Samsung S7 Edge to Chromecast 2 to work: reboot phone

Posted by jpluimers on 2018/09/25

A friend of mine tried to get screen mirror (now called “Smart View”) from a Samsung S7 Edge to a Chromecast 2 working, but the connection would time out each try (but not when casting regular content using the Google Home app): try rebooting your S7 Edge.

Got that reboot tip and renamed functionality thanks to the somewhat related [WayBack] Galaxy S7: How to Screen Mirror to any Samsung Smart TV:

In order to connect (screen mirror) you Galaxy S7 or S7 Edge to your Samsung smart TV you need to swipe down to open your notification area, then on the top right click that little down arrow then select “smart view”. Previous Galaxy phones called it screen mirror, not sure why Samsung changed the name in the S7.

Got the renamed functionality via the video below.

Unicode spaces

Posted by jpluimers on 2018/09/25

For my link archive:

Via: [WyBack] Are there blank characters in unicode that have the same widths as period, comma and digits? – Lars Fosdal – Google+

Answer: no, though better fonts have period, comma, colon, semicolon and other punctuations the same width as the punctuation space.

The use-case:

I wanted right justified text without having to do custom positioning/drawing – where the decimal zero is white space.

F.x. here 12 instead of 12.0

9.5
11.6
12 <– #$2008 and #$2007
13.4

I.e. PunctuationSpace and FigureSpace

I don’t want to deal with positioning/rendering since it happens inside a third party component.
