Latest Mac’s build in hardware test

Wednesday, March 1st, 2017

Historically there was an Apple hardware test that you could boot to check if your Mac’s hardware is all good.

It came to a surprise though, that with newer Macs simply holding the ‘d’ during power on it runs some simple hardware diagnostic, too.

One should probably more often read Apple’s support pages, ..

TEAC HR Audio Player for iOS

Thursday, January 5th, 2017

This thing, when you buy a Teac HA-P50 for some Hi-Res Audio testing, and the matching iOS app (you know, for hi-res, FLAC and such, …, sigh) produces extremely audible clicks and pops that sounds like buffer under run / overflow / whatever - on a recent iPhone 6s no less.

What the heck are the vendor’s thinking to ship such crap to their premium paying customers?

Funny thing, other apps, such Apple’s own Music.app do not have this clicks and pops, … ???!!!

Judging from the App review an at least one year old problem:

PS: And why the heck do they sell the Teac HA-P50 for US$199 in the states, and for 299€ in Europe?

Random cloud changes

Friday, October 21st, 2016

For a while I already watched some other business struggling with workflow inefficiency by using cloud services that randomly (like monthly) change some user interface, options etc. and thus waste hours and hours of the time of workers to actually get their work done.

While we protect our data and investment by not using cloud services for anything productive (exception like Google Adwords, …) today we hit a similar issue. I automated invoice generation from our online store PayPal email notifications. Some days ago on October the 15th PayPal deviced out of the blue sky that it would probably be nice if they modernized their email templates.

Well, great for them, no so for our nicely script automated invoice generation. But even for the users:

Before the PayPal notifications where: Content-Type: multipart/alternative; with a Content-Type: text/plain; charset=UTF-8 and a Content-Type: text/html; charset=UTF-8 and about 20 kB in size.

Unix veterans could still nicely read the text/plain part in pine, mutt or wherever. The new emails did away with the text/plain part, and only send a Content-Type: text/html; charset=UTF-8 and the designers even blew that up to now consume a whooping 90kB.

Worst of all as of today they still send us a mix of old a new template based emails. Obviously awesome for some reliable processing, …

So this is what the silicon valley companies call progress? :-/

Update: Most of the size increase is actually mobile optimization CSS. WTF optimization is that? I rather have a smaller, plain text email than a 80kB CSS monster when I’m on the go :-/

Can the tech industry please stop messing with everything and thereby actually making things worse? :-/!

Screen on a serial port

Friday, September 16th, 2016

Although I use and develop on Linux for a very, very, very long time it never had the idea to use screen as a terminal emulator on a serial port for an embedded board.

Turs out that is very well support and just works:

screen /dev/ttyUSB0 115200

Getting tired of permanent MacBook battery failure

Friday, August 26th, 2016

So this stupidly smart Apple MacBook batteries set a permanent failure bit once they are simply discharged by sitting on a shelf for a month or two. With this permanent failure bit the controller will not charge them again, even when the cells are brand new and otherwise perfectly fine. Another day I need to try sending a reset sequence or otherwise rewriting some flash cells, sigh:


Some notes for now:

Amazon BuyVIP

Wednesday, July 20th, 2016

Recently Amazon started to spam my email account regarding their http://de.buyvip.com rebranding / “microsite”. I really wonder about Amazon’s benefits in this case, why not simply run this from their main site, … Lure those people back who are not satisfied with the Amazon experience by using another brand? Or some special mass promotion sales contracts?

Religionsschlüsselverzeichnis

Monday, January 18th, 2016

In 2015 wurde das Meldeverfahren für Kapitalerträge für Kirchensteuern geändert, und dabei neue, komplizierte, und nicht oft publizierte Religionsschlüssel eingeführt. Schulder müssen sich jetzt theoretisch beim Bundeszentralamt für Steuern für die Abfrage dieser Schlüssel schriftlich anmelden, und dann jährlich den Religionsschlüssel elektronisch abfragen (WTF?). Da man diese im Internet nicht oft findet hier eine kurze Textaufstellung. Da nicht von mir erdacht und nur von Staatsquellen übernommen keine Gewähr auf Richtigkeit oder Vollständigkeit:

BootCamp driver download

Sunday, January 10th, 2016

So Apple does not publish nice Windows driver downloads, you need the BootCamp.app for that, sigh. You need to download hundreds of megabytes even if you only need a driver, or two, sigh.

And where does it store it? /Library/Application\ Support/BootCamp/

The new face of Apple

Wednesday, January 21st, 2015

I never quite liked that new Macs do not come with any installation media anymore. In former times you got pretty optical discs. But since the DVD-less Mac’s and the App Store one get’s “nothing” anymore :-/

The trouble comes after some time, when you want to reinstall your OS. Case in point: I wanted to install the latest OS compatible with the black, polycarbonat (awesome, stylish [did I say black?] machines, btw. - except the breaking plastic border, unfortunately). Turns out the App Store does not allow to download my “purchased” 10.7 with errors such as: “Item temporary not available” (or so).

With billions on the bank account: Why does Apple need to be so unsupportive and impolite to good old customers - when they already do not support recent, security updated OS versions on the slightly older machines, ..?

So not only can I not (without hacking and tweaking) install 10.8 or 10.9 on this still nice Macs form just some years ago. I can not even download the last supported Mac OS (10.7) to at least get some latest (and not so greatest) security updates.

This state of this former computer company is really sad.

Thankfully I often burn some backup discs, especially for installation on more than one Mac, and thus found a self-burned Mac OS 10.7 Lion disc in my archive stack and could install it on this Mac in point after all.

And this is not only about the base OS - with the current App Store implementation we will often find ourselves with purchased software, that we can no longer download for older OS and hardware in the future.

Like today being able to install vintage (and often still pretty useful) versions of an OS, and applications. Often even expensive ones: Photoshop, InDesign, Acrobat Professional, … and games. How much fun is it to boot up some vintage game from the Amiga, or old PC and play thru it again, with your kids, or friends?

What dim, brave new world, … :-/

Timing code on Win~32, sigh

Monday, December 29th, 2014

The wonders of the WinDOwS DOS legacy. Not only does the the command line (cmd.exe) totally suck, one even needs to resort to the new, and not much less sucking powershell for some halfway decent command time scripting:

Measure-Command { cmd /wait /c our.exe args }

Alien, “fun” :-/
