• Hunor Márton Borbély ☛ Day 11: How to Draw Quadratic Bézier Curves with SVG

  The path element becomes really powerful when we start using curves. One of them is the quadratic Bezier curve. We not only set the endpoint but we also have to set a control point.

• Hunor Márton Borbély ☛ Day 12: How to Draw Cubic Bézier Curves with SVG

  While the quadratic Bézier is great when we want to bend a line, often it’s not flexible enough. With cubic Bézier, we not only have one control point but two. The first control point sets the initial direction of the curve and the second one defines from which direction should the curve arrive at its endpoint.

• Eshel Yaron ☛ Alignment in Emacs

  See? Nice and tidy. Something about putting similar things on the same column of consecutive lines just feels… right. I think it has something to do with clarifying the meaning of the code by visually identifying parallel constructs. It’s like putting these lines into a little table that we mentally annotate with column names. Anyway, this business of adding meaningless whitespace to make things pretty is called alignment, because we align parts of different lines to the same column. But aligning code manually can be quite a hassle.

• Manuel Matuzović ☛ The hidden attribute in HTML

• Martijn Braam ☛ Looking closer at the syslog

  I've started looking into syslog implementations when building a replacement for the use of busybox syslogd in postmarketOS. In postmarketOS this daemon is configured to just send syslog messages to a in-memory buffer for logging and never store anything on disk in /var/log. This is mainly to make sure there's no unneeded writes to the flash storage in a lot of the old phones that are supported by postmarketOS. There's a few downsides to this logging implementation though: [...]

• APNIC ☛ That OSI model refuses to die

  I don’t entirely agree with his analysis. I have to admit I am biased having worked in this space myself from 1982 (on early implementations of the OSI Transport classes 1, 2, and 3, written as a finite state machine in PL/1 on a VAX VMS system in the UK) and again in 1985/6 (working in UCL-CS in London, on what became the ISODE system designed and implemented under the aegis of Marshall Rose) and then latterly working in the applications space on the X.400 and X.500 systems (email and directory services respectively). So, I have far too much skin both ‘in the game’ and ‘left on the roadside’ from working in the space repeatedly.
