    Fonts annoy me. So many licences, variability and availability and differences machine to machine. Like standards I suppose so many to choose from and non completely compatible.

    • Fonts are a huge issue because we need them to, you know, communicate. The license you are looking for is "completely free to use and modify". That way you know that not only are you able to use it, but the font is going to be maintained and stick around, making life easier for everybody.

      The typography landscape is littered with quality fonts that nobody uses because they are not free to maintain.

      Fonts annoy me. So many licences, variability and availability and differences machine to machine. Like standards I suppose so many to choose from and non completely compatible.

      Well, the standard is pretty much the Microsoft-Apple TrueType (designed as a competing standard to Adobe PostScript fonts). (Yes, Microsoft and Apple worked on TrueType together, during the 90s when they were fierce enemies). Even then it's not a simple spec because it's actually quite difficult to lay out text nicely.

      One of the jobs of a typesetter is to actually arrange the page so the text flows properly, and it's more of an art than a science. It's why TrueType implements a virtual machine to help with the automatic arrangement of characters.

      It's also why designing a font is damn hard - creating the character shapes is the easiest part, but doing the necessary back end work to ensure it looks pleasant to the eye no matter the word/letter combinations is difficult (hence the virtual machine). And then there's Unicode, so you have to way more shapes to contend with (luckily a lot of them get by with monospace).

      Finally, the licenses reflect the fact that fonts are a tool - so there's a lot of complexity in them. First, printing them out means having to send the font over at times (if it's not rasterized locally), so you need to enable translation of the font to the printer's natively language. Then you need to consider that electronic documents may need to embed fonts in them to look the same on every computer, even the ones without the font, but that embedding is now distribution of the font.

      The license is complex purely because copyright law doesn't cover it terribly well. Embedding is a form of distribution and derivative work. Printing can mean creating a derivative work so the printer can rasterize it. Then there may be distribution if you want to send it to a printing press so they need the font as well...

      As for raster fonts - they're great, but when you're dealing with high res screens, they start to show their chunkiness. I just wish some of the nice raster fonts were availble as TrueType so they can scale up nicely and be razor sharp on high res "retina" screens.

        That's kerning. TrueType solves this problem with a static kerning table.

        The virtual machine is for hinting - adjusting the outlines so that they still produce reasonable bitmaps at small point sizes. It has nothing to do with the flow of text.

              Let me be more specific. Think about a lower case m. We want each of the three vertical strokes to look exactly the same, even if antialiased. Your eye will really complain if this isn't the case, even on a high resolution display. (If not then don't worry about it, quality anything is not for you. You can save a lot of money on stereo equipement.) Hinting will adjust those three strokes to be equally separated in terms of pixel units, even if exact alignment to pixel boundaries is not possible. Then if you display the same font much larger, the strokes will be allowed to move to the exact positions defined by the artist. Hopefully, showing good taste. That's just the beginning of it, hinting a huge and subtle topic. Trying to pretend it doesn't matter, or actually lowers quality, does nothing but demonstrate ignorance.

        But then, no sane coder uses a light background for coding, right?

        Actually a light background is (somewhat counter-intuitively) easier on the eyes, especially in dim lighting scenarios. The reason comes down to the optical properties of your eyes, which we can talk about in camera terms. A narrow aperture creates a broad depth of field, while a narrow aperture creates a very shallow depth of field. Bright scenery requires a narrow aperture and a broad depth of field, while dark scenery (is certainly moodier) requires a wide open aperture and a very shallow depth of field.

        That means that the brighter things are, the smaller your iris is, the more movement you can have in your head without your screen really going out of focus. Very dark setups with dark code (the stereotypical coding setup, it certainly looks cool) actually lead to more eye strain than a bright working environment and white background on your code. Eye strain is caused by constantly shifting focus, and that is alleviated by bright environs and bright code. Dark setups can require only a few millimeters of movement before your eyes are having to refocus. Bright setups can give you several centimeters of movement.

          That's one cause. Excessive illumination is another, as a person with sensitive eyes quickly discovers after staring at a white background for a few seconds and experiencing strain and tearing. Focus changes in particular, do not cause eyestrain in nearsighted people because we are used to blur and have acquired the ability to read text through a much wider depth of field.

          Whatever the cause, brightness sensitivity is much more common among the coders I know, and white backgrounds are the worst possible thing to look at. This used to be exacerbated by CRTs with 60Hz default refresh rate. Looking at the 60Hz white background of a default Windows installation causes eyestrain and tearing within thirty seconds, making any work impossible without deep squinting. We thus become proficient at switching the color scheme as quickly as possible. Windows 7, of course, makes this more difficult, as Aero does not support changing the theme background, so a classic theme must first be enabled.

      But once you get into smaller sizes, pixel fonts have to do weird things to their shapes (like the 4x6 windows bitmap font), whereas antialiasing and subpixel rendering can actually express more shape per pixel for greater readable density. And for larger fonts, curves sweep over many more pixels and it starts to look jaggy without handling vectors.

  • This new font aint too bad, but unfortunately it doesn't work well as terminal font as GNU Unifont does, also limited Unicode support is a problem. And * is totally wrong in this font, it should be 6 pointed and same size and location as +, like in Unifont: http://www.inside.org/~raynet/unifont.png [inside.org]

  • Too big. Need to show how it renders in smaller sizes, as that's how it will be used for coding.
