Mac OS XmacOS has come with a new default wallpaper. As you can see, I have collected them all here.
While great in their day, the early wallpapers are now quite small in the world of 5K displays.
Major props to the world-class designer who does all the art of Relay FM, the mysterious @forgottentowel, for upscaling some of these for modern screens.

With the protocol being completely open and ready to be integrated into any home automation interested users can either utilize the publicly available (stores-nothing-on-disk) server or host your own.
Everything from the server to the clients is available in source and there’s a ready-to-go version of the client app on the AppStore.
Don’t delay, order today! It’s in store since, actually right now. You won’t even find it through search yet!

I’ve finished my little coding exercise today. With a good sunday afternoon used to understand and develop an iOS and Watch application from scratch I just handed it in for Apple AppStore approval.
The main purpose, aside from the obvious “learning how it’s done”, is that I actually needed a couple of complications on my watch that would show me the current day/date in the discordian calendar.
I have to say that the overall process of developing iOS and Watch applications is very streamlined. Much much easier than Android development.
The WatchKit development was probably the lesser great experience in this project. There simply is not a lot of code / documentation and examples for WatchKit yet. And most of them are in Swift – which I have not adapted yet. I keep to Objective-C for now still. With Swift at version 5 and lots of upgrades I would have done in the last years just to keep up with the language development… I guess with my choice to stick to Objective-C I’ve avoided a lot of work.
Anyhow! As soon as the app is through AppStore approval I will write again. Maybe somebody actually wants to use it also? :-)
With writing the app I just came up with the next idea for a complication I just really really would need.
In a nutshell: A complication that I can configure to track a certain calendar. And it will show the time in days/hours/minutes until the next appointment in that specific calendar. I will have it set up to show “how many hours till wakeing up”.
I’ve started to write a watch app for iOS/WatchOS which is going to display the current calendar information according to the discordian calendar.
Since there’s no watch support on any of the calendar apps in the AppStore and I wanted to have easy to use watchface support I had to try it myself.
I will update here on the progress but so far it looks like this:
We are using Apples smartwatch to measure some health stats during our workouts. And Apple Watch is doing a great job at that.
With all that polish one would expect better from what Apple has to offer in the software department…
Apple Watch has monthly challenges that get automatically generated from previous measurements. But seeing that an already much above average activities number would have to be doubled to complete the challenge is absurd. To a degree where challenges are arguably health risks…
Apple has started to force developers that want to develop and publish on the MacOS and iOS platform to enable two-factor authentication.
Two-factor authentication (also known as 2FA) is a type, or subset, of multi-factor authentication. It is a method of confirming users’ claimed identities by using a combination of two different factors: 1) something they know, 2) something they have, or 3) something they are.wikipedia
When I just got around enabling it for one of the apple accounts I’ve got there seems to be a much much higher security barrier in place already…
That’s probably some sort of zero-factor no-authentication. I guess. Anyway: Kudos to Apple for finally forcing people to minimum standards. Properly integrating the second factor will make this so much simpler for users. Apples ecosystem solution already is quite well integrated.
Have you switched all your daily used services to two-factor authentication yet?
We’ve got a couple of SONOS based multi-room-audio zones in our house and with the newest generation of SONOS speakers you can get Apple Airplay. Fancy!
But the older hardware does not support Apple Airplay due to it’s limiting hardware. This is too bad.
So once again Docker and OpenSource + Reverse-Engineering come to the rescue.
AirConnect is a small but fancy tool that bridges SONOS and Chromecast to Airplay effortlessly. Just start and be done.
It works a treat and all of a sudden all those SONOS zones become Airplay devices.
There is also a nice dockerized version that I am using.
There have been several occasions in the past years that I had to quickly change the MAC address of my computer in order to get proper network connectivity. May it be a corporate network that does not allow me to use my notebook in a guest wifi because the original MAC address is “known” or any other possible reasons you can come up with…
Now this is relatively easy on Mac OS X – you can do it with just one line on the shell. But now there’s an App for that. It’s called Spoof:
“I made this because changing your MAC address in OS X is harder than it should be. The Wi-Fi card needs to be manually disassociated from any connected networks in order for the change to apply correctly – super annoying! Doing this manually each time is tedious and lame.
Instead, just run
spoof and change your MAC address in one command. Now for Linux, too!”
“Commands have been a big part of computing ever since the 1970’s. Their power comes from their simplicity. Just type a word or two to do what you want. The time has come to bring this power together with the usability and convenience of modern interfaces.”
“Xiki is open and flexible. It’s open source, and brings together tools, languages, shells, and text editors, rather than competing with them. Open formats and languages are the best thing for the tech ecosystem. HTML and JSON made the web what it is today. And the web arguably made everything else.
Xiki strives to be the simplest possible way (and ways) to create interactive interfaces. This means a text in and text out interface. Since everything is text, almost nothing is against the rules when you’re creating an interface in Xiki. Xiki stands for “expanding wiki”, and is inspired by the wiki philosophy of fully editable text, with simple syntaxes (like “>” for a heading, and “-” for a bullet). Xiki extends wiki ideas to user interface in general.”
Airplay allows you to conveniently play music and videos over the air from your iOS or Mac OS X devices on remote speakers.
Since we just recently “migrated” almost all audio equipment in the house to SONOS multi-room audio we were missing a bit the convenience of just pushing a button on the iPad or iPhones to stream audio from those devices inside the household.
To retrofit the Airplay functionality there are two options I know of:
1: Get Airplay compatible hardware and connect it to a SONOS Input.
You have to get Airplay hardware (like the Airport Express/Extreme,…) and attach it physically to one of the inputs of your SONOS Set-Up. Typically you will need a SONOS Play:5 which has an analog input jack.
2: Set-Up a RaspberryPi with NodeJS + AirSonos as a software-only solution
You will need a stock RaspberryPi online in your home network. Of course this can run on virtually any other device or hardware that can run NodeJS. For the Pi setting it up is a fairly straight-forward process:
You start with a vanilla Raspbian Image. Update everything with:
sudo apt-get update
sudo apt-get upgrade
Then install NodeJS according to this short tutorial. To set-up the AirSonos software you will need to install additional avahi software. Especially this was needed for my install:
sudo apt-get install git-all libavahi-compat-libdnssd-dev
You then need to get the AirSonos software:
sudo npm install airsonos -g
After some minutes of wait time and hard work by the Pi you will be able to start AirSonos.
And it’ll come up with an enumeration of all active rooms.
And on all your devices it’ll show up like this:
While I am using Xcode a lot lately I quickly got used to one or two keyboard shortcuts that come in handy once every while. This cheat sheet aims at bringing you a lot of shortcuts that are pretty hard to remember if you’re not using them all the time (at least for me).
Since I’ve become sort of an iOS developer lately I had my fair share of WWDC recordings to get started with this whole CocoaTouch and Objective-C development stuff.
Now a tool that is pretty handy is a this website that offers a full-text transcript search of all WWDC recordings. Awesome!
If you want to interface with the publicly available instance of the miataru server you can use the URL: http://service.miataru.com. This URL also is pre-configured with the iOS client that got recently available in the AppStore.
Obviously it’s impossible for Apple to fix that quite annoying bug in their operating system that leads to double/tripple/… program entries in the “Open with…” menu. Everytime an application is updated it adds a new entry but does not remove the old one.
This makes your open-width menu look like this:
/System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -kill -r -domain local -domain system -domain user;killall Finder
This simple command will kill the double/tripple/… entries and restarts your finder.app to make the change visible. Your “Open with…” menu should now only show singular entries per application:
Configuring your favourite Editor on OSX (or Linux, or anywhere else) is important – since nano is my editor of choice I wanted to use it’s syntax highlighting capabilities. Easy as pie as it turned out:
I started with a .nanorc file from this guy and modified it to recognize some of my frequent file-types (like .cs files).
You can download my nanorc.tar – just extract it and put it into your user home directory.

It’s been some
months years since the once Microsoft Research Project got public and Microsoft started offering it’s great Photosynth service to the public.
I’ve been using the Microsoft panoramic and Photosynth tools for years now and I tend to say that they are the best tools one can get to create fast, easy and high-quality panoramic images.
There is photosynth.net to store all those panoramic pictures like this one from 2008:
The photosynth technology itself contains several other interesting technologies like SeaDragon which allows high quality image zooming on current internet connection speeds.
This awesome technology is as of now available on the iPhone (3GS and upwards) and it’s better than all the other panoramic tools I’ve used on a phone.
Oh boy, it seems that Apple just screwed up big time when it comes to data privacy. Obviously everytime someone attaches an iOS device like the iPhone to a PC or Mac and it does a backup run this backup includes the location data of that iPhone of the last several months. Impressive logging on the one hand and a shame that they did not talk about that in public upfront on the other hand.
There’s a great tool available on GitHub which uses OpenStreetMap to visualize the logged data – it creates a quite impressive graphical representation of where I was the last 6 months…
I am using the Apple AirPlay technology for several years now… after it got implemented into iOS it’s just fantastic to have the option to have whatever sound source I want to playing loud and clear in any room I want to…
Okay it’s not quite as sophisticated as the sonos solution regarding the control of multiple music sources in multiple rooms but it get’s the job done in an apartment.
So back to the topic: Apple integrated the AirPlay technology into their wireless base station “AirPort Express”. Basically AirPlay is a piece of software which receives an encrypted audio stream over the network and outputs the stream to the SPDIF or audio jack.
Back in 2005 there already was an emulator of this protocol called “Fairport” but Apple decided to encrypt the AirPlay traffic. This led to the problem that the encryption key was unkown because it’s baked into the AirPort Express firmware. And this is where the good news start:
“My girlfriend moved house, and her Airport Express no longer made it with her wireless access point. I figured it’d be easy to find an ApEx emulator – there are several open source apps out there to play to them. However, I was disappointed to find that Apple used a public-key crypto scheme, and there’s a private key hiding inside the ApEx. So I took it apart (I still have scars from opening the glued case!), dumped the ROM, and reverse engineered the keys out of it.”
So to keep things short: Someone got an AirPort Express, dumped the firmware, extracted the AirPlay encryption keys and wrote an emulator of the AirPlay protocol which uses the key. Voilá!
ShairPort is available in source code on the site of the guy and obviously it’s unsure if Apple will react by changing the encryption key in the future. But for the time being it works as advertised:
I took one of my computers and followed the instructions to update perl, install Macports and then run ShairPort. So when ShairPort is run it looks not as appealing as expected:
Notably it uses IPv6 to communicate between iTunes and ShairPort… Oh I almost forgot to show how it looks in iTunes:
On another side note: It works on Linux, Windows and Mac OS X :-)
So finally after years and years of hope and nerdy ideas I am able to hold a tablet device in my own hands and it’s not only as good as Picards tablet was back in that great “Star Trek: Next Generation” series, it’s better.
Of course I had to import that particular iPad from the U.S. (thanks Alex!) – actually it was the first time I imported something that expensive. Beside some fun with the shipping company everything went fine. Since Apple just announced to delay the launch of the iPad in Europe for a month it’s nice to have a gadget just a few weeks after it was available in the U.S.
Thanks to a podcast I found a great software for my iPhone and iPod touch. It’s a small tool which does cost less than 3 Euro and it’s served by a server tool which runs on Windows and Mac OS X.
It’s called Air Video and it’s frikin’ awesome! ™
What you do is you install the server software and point it to all your directories / drives that might contain video material. You then take your iPhone and install the client app. If you configured the server to be available over the internet you can now connect from anywhere you want using a pass-pin (which is generated) and a password (which is set by you). And by “from anywhere” they mean “anywhere”. WLAN or 3g didn’t make any difference in my test. You start the client, point to a video file and most of the time you are asked if you a) want to directly play is (if the file is ipod-compatible) or b) if you want to live-convert it and play it (when the file isn’t compatible and needs to be re-encoded live for you) or c) if you want to add the file to a conversion queue which will off-line convert the video for you.
In terms of “finding your video” it does look like this:
Simple, eh? Taping a video will bring up this screen:
As I said – Play directoy, Play with Live Conversion and Offline-Conversion-Queue…
It did work with EVERY Video I tried. When I tried Full-HD Movies my serving PC wasn’t able to handle the load but everyhing in SD worked great which is perfect for me.
Therefore I can highly recommend this tool – it really does work better than anything I’ve seen before.
It’s also suitable for anyone who wants to develop iPhone Applications.
“I started investigating how I might wire up — and then write native iPhone apps from — a scripting language. Lua was on my radar already. It’s compact, expressive, fast enough, and was designed to be embedded. Took only about 20 minutes to get the Lua interpreter running on the iPhone. The real work was to bridge Lua and all the Objective-C/CocoaTouch classes. The bridge had to work in two directions: it would need to be able to create CocoaTouch objects and also be able to respond to callbacks as part of the familiar delegate/protocol model.”

Last week I upgraded my iPod touch to an iPhone… well actually I got a new iPhone 3GS aside the iPod.
It’s a fast device – even noticeably faster than the 2nd gen iPod Touch. It’s got almost the same battery life like the touch for me and it was a plug-and-play experience to use it the first time.
What I wasn’t expecting is that the smooth experience suddenly came to a stop when I tried to plug the iPhone into my car – just where the iPod touch did the job for about 5 months (including that the touch got charged by the car along the way).
With the iPhone I got two error messages simultaneously:
“Charging not supported by this accessory”
“This accessory is not supported by iPhone”
Damn you Apple! What’s the problem? There’s a standard USB port which powered 2,5 inch hard disk drives previously and the iPhone just states that it cannot be charged with this accessory (e.g. the car).
On the other hand everything else just works as it was working with the iPod. I can browse my music library on the iDrive I can listen to music – everything works, beside those two error messages and the not-charging iPhone. Thank you Apple B-) Maybe I need to up-grayed my car too?
After not less than 3 and a half hour Songbird finished with importing the iTunes library I am using for about 6 years.
The first impression is: Cool, it’s got plugins!
The second impression is: Booh, it wants to restart (while stopping the music) to install!
It’s not faster than iTunes. And this is a sad thing, because the only thing I hoped it would be was faster. It’s not – the UI it’s as fast and responsive as iTunes’ UI – at best. With just a few clicks the whole songbird window went into sleep mode and the well known beachball came into the play.
Even worse: for some strange reason Songbird consumes considerably more CPU time while just sitting there and playing an MP3 than iTunes does:
18,7% CPU load used by songbird just by playing an mp3 (no filtering, no visualisation, no nothing)
2,3% CPU load for iTunes while doing exactly the same. Even the same mp3 was played.
iTunes even takes less memory… oh dear: A long way to go for the Songbird team.
So it’s been some days with the new Mediacenter Setup. And all I can say is: Oh boy that is some serious cool setup. I wouldn’t want to chance anything beside adding a new Sound System (>5.1 FTW!).
The Display itself is thinner than thought:
I strongly recommend the Mac + Plex + Full HD display setup. Even if you don’t get any HD content from your cable provider you can live-stream or download HD content through the different provider plugins inside Plex. The plugin infrastructure with the built-in “App Store” is just great.
Since Plex is a XBMC based Mediacenter software you have tons of information scrapers regarding series and movies. So you’re eventually huge collection gets indexed and presented in a way you would not get from any other Mediacenter. You get pictures, movie posters, descriptions and many more just by automatic indexing your collection.
Needless to say that HD content is something different. I only had some HD content on normal computer displays in the last years – having it now huge and sharp is different – better.
BTW: It’s on the floor right now because my wife couldn’t decide until now which tv-stand would suffice…
Finally after more than 10 weeks of waiting the ordered Apple MacOS X Finder Pillows arrived at our door.
Let’s say you’re like me: You got several audiobooks on CD over the years and you even ripped several of these to listen to them in your MP3 player/car.
So what I have is a number of audiobooks ripped as mp3s on my harddisk looking something like this:
If you only have the CD what you would like to do is rip the whole CD as ONE large m4a AAC encoded audiofile. We need it to be an m4a because we later want to inject chapter marks. If you have this big AAC file just skip the next few steps. But if you got those several small mp3 files – one for each chapter you want to merge them together and reencode them as m4a AAC.
There is a great free tool to merge these mp3 files together. It’s called (who would have thought) Merge MP3 and is available completely for free. It’ll create one big mp3 file out of your several small ones.
After you got that huge mp3 file you want to convert it into a m4a file with AAC encoding. I recommend using iTunes.
When you got that one huge m4a file you want to load it into a tool called Chapter Master. It’s not free and will set you back $15 but it’s worth as I did not find anything else that was a) that cheap b) that comfortable c) working.
Load the m4a file into Chapter Master, add the chapters in the right order and at the right time. Eventually you want to add an album art picture. Click save and you’re done.
The resulting file is a m4b file recognized by iTunes as an audiobook with chapters.

Turns out that a new snapshot (unofficial) version of my favourite DVD to iPod Converter is available. With the new version came new features like the one that allows me now to convert almost anything to wonderful iPod compatible movie files.
“HandBrake is an open-source, GPL-licensed, multiplatform, multithreaded DVD to MPEG-4 converter, available for MacOS X, Linux and Windows.”
I tried anything in my library, including some matroska movie files. Just everything worked – amazing!
In May 2005 I wrote about a wish I had for years:
“As usual I’ve got a very strange wish what nobody else seems to have on this planet. I have several computers of different platforms. And on one of this machines there are speakers attached…I want to have the possibility to output from any of the machines to the speakers. And please loss-less and low latency!”
It took more than 3 years to fulfill this particular wish. But now it’s done. In 2005 I mentioned the Airfoil software that could run on MacOS X and forward sound from almost every application to an AirTunes compatible device. As it turns out Rogue Amoeba did their homework and created a free “Airfoil Speakers” application which can be used on Windows and MacOS X.
So the things are simple: Start the speaker application on a machine that is in the same network/subnet as the Airfoil master. The virtual speaker is then displayed on the master machine and you can assign a sound source from that machine to the speaker. Hmm… Simple Setup sample: One machine is in my kitchen (Windows XP machine) and one machine is on my desk – an iMac. In the kitchen only the speaker application is started and the iMac instantly “sees” the speaker. One click and the sound output of my desk machine is forwarded through the network to the kitchen… Easy and cool. One can think of any other combination of Speaker/Master application – even multiple speakers can be powered by one master…oh joy!
So here is what the master looks like:
and this is what it looks like on a client (speaker):
