Fibonacci, der Goldene Schnitt, Processing und ich

Einhundersiebenundreissigkommafünfgrad

Nach der Kopfdruckbetankung vor knapp zwei Wochen auf der Reasons to Konferenz in Brighton habe ich mir ja vorgenommen, mich wieder mal mit Processing zu beschäftigen. Da ich mich seit der Konferenz nicht vor dem heimischen Rechner befand, habe ich mir eine auf processing.js basierende App auf iPad geladen und die letzten Abende damit rumgespielt. Und siehe da, nach etwas hin und her und merkwürdigen Ergebnissen zwischendurch ist mir das erste Mal eine "schöne" Grafik gelungen. Ich verstehe immer noch nicht, warum das so ein wunderbares Muster ergibt, sobald ...

WordPress 4.6 "Pepper" ist da

wp

Vor drei Tagen ist die neue WordPress Version erschienen.

New features in 4.6 help you to focus on the important things while feeling more at home.

Hm, na dann… :-)
In den paar Installationen, die ich schon aktualisiert habe, lief alles glatt und ohne Auffälligkeiten, daher drücke ich nun auch hier in der Bloghütte den Update Button.

Getting flexible with two speakers in one cabinet

speaker-1_wiring

Years ago I found an old Reußenzehn cabinet with two 12" speakers in an old rehearsal room that we cleaned up. Since neither the speakers nor the cabinet beared any markings regarding impedance and wattage, I was reluctant to use this box, and so it kind of hybernated for quite some time now.

In the last weeks I worked on two tube amps, changing power tubes, setting the bias, and one transistor amp, where I repaired a blown power section. So it turned out that I have a need for a relatively small and compact cabinet to test ...

A Front End Developer is Aware - Chris Coyier

In a general sense, the front end developer is positioned in the middle of lots of other jobs. Everybody involved in a web team ends up talking with the front end developers. That makes sense. The front end developers create the actual thing people interact with. Everything comes together with the front end developer. Perhaps that's why it's such a fun job!css-tricks.com

WordPress 4.5.3 Security Release

wp

Gestern abend ist eine neue Version mit Sicherheits- und Wartungsfixes erschienen. Bei den diversen Installationen, in die ich involviert bin, hat sich das automatisch aktualisiert, auch bei älteren Versionen als 4.5.2, wie gehabt gibt es die Source aber auch zum Download auf wordpress.org.

WordPress versions 4.5.2 and earlier are affected by several security issues: redirect bypass in the customizer, reported by Yassine Aboukir; two different XSS problems via attachment names, reported by Jouko Pynnönen and Divyesh Prajapati; revision history information disclosure, reported independently by John Blackbourn from the WordPress security

Ch-ch-ch-changes

For a long time it has bugged me that the css for the recent version of my site was desktop-down. I made some adjustments for adaptive/responsive behaviour three or four years ago, but since the code base of my site is organically growing since I started it on WordPress in 2005… uhm, I think you get the picture. So all I did back then was to consider how the site should look on smaller screens, and making modifications inside max-width media queries, keeping all of the desktop-related stuff as the default styles, outside any media queries.
Of course when starting ...

Revisiting the Service Worker / Offline cache

Motivated by the sudden appearance of the "Add to home screen" prompt, I spent the last couple of hours to tune my Service Worker / caching behaviour:

- I can now exclude parts of my site from the service worker. This was an important feature for me, since the WordPress backend didn't sit too well with stubborn cached items.

- I established a number of caches for different items:
-- a "static" cache that has the base css and the page that gets displayed when the network is offline.
-- a "content" cache, that stores up to 25 URLs a visitor has, well, visited, while being online.
-- an "image" cache, that stores up to 45 image files, and finally
-- an "asset" cache for up to 35 files (everything that is not HTML and not an image).

The limits are rather random, but I think each cache has an build-in maximum of 50 entries (?), so to see if it works, I choosed numbers smaller than that.

Progressive Web(rocker)App

Ha! It! Really! Works!

I have to admit I was a bit sceptical of the outcome after I tweaked and added things and bits of my website at the Indiewebcamp in Nuremberg, setting up a service worker and offline caching things, adding a manifest file … while in theory I understand what all of this was supposed to do, I felt a bit dumb for not completly grasping how to control the stuff.

So as so often when learning new tricks on the web, it started with copy/pasting a working solution and trying to adapt this to my ideas.

But ...
