Building an Ergodox

2015-03-03 (143) by Ton Kersten, tagged as news

After a lot of thought I decided it was time for a new project, one I would enjoy and a project that would be useful for a long time.

Searching the web and reading articles I found the ErgoDox.

The ErgoDox is a split-hand ergonomic keyboard with mechanical switches and open source, layer-based firmware running on a Teensy microcontroller. While other keyboards offer dip-switches or GUI config tools, the firmware and layouts can be built from source on the command line or through a layout configuration tool. Flashing a new build onto the ErgoDox is easy with the multi-platform Teensy loader.

I immediately got interested and after searching a bit more I ordered the kit at Falbatech. Unfortunately they do not supply the keycaps, so I ordered them from Signature Plastics.

CDE is Open Source

2012-08-06 (125) by Ton Kersten, tagged as code, linux, news

Today the classic, and old, Common Desktop Environment (a.k.a. CDE) was released into the Open Source world.

You can get the very alpha version at SourceForge.

I haven't been able to get a running version by now, but I keep trying.

Good job, guys.

Yeah, I found it

A very long time ago, when I was still studying computer science I had a HP15C calculator. And I realy loved it. Unfortunately it was stolen and I couldn't afford to buy a new one. I ended up using a Casio FX602p. A very, very good calculator, but it's not a HP15C.

Last Friday I was discussing old times with a nerd like me and we ended up discussing calculators and what the heck, he had used the HP15C as well and hated HP for stopping to sell it, as wel as I do.

So I started digging the internet and this is what I found:

HP 15C emulator

A HP15C emulator for Linux, Mac OSX and Windows. I use this one now at a very regular basis and I really love it.

If you want to give it a try, look at Torstens site and, please, give Torsten a heads up.

No more WikiLeaks?

2010-12-03 (81) by Ton Kersten, tagged as news

The WikiLeaks site cannot be reached. This is because their free DNS provider removed the DNS records.

wikileaks DNS ended

The last IP address was, but nobody is answering the http requests.

Looks like they where shutdown.

HP's newest invention

2010-10-25 (76) by Ton Kersten, tagged as news

HP has got something new again: HP ePrint.

This surely comes from the 'Useless inventions department'.

What is ePrint?

This lets you print from virtually everywhere. One of the ways that ePrint works is to assign an email address to your printer. To print, simply send an email containing your document to your printer's address. You can print images, Microsoft Word, Excel* and PowerPoint documents, PDFs, and photos. You can view and manage print jobs sent to your printer using your printer Job History that is available on HP ePrintCenter.

The following email clients have been tested by HP ePrint:

  • Outlook 2003, 2007
  • Hotmail, Yahoo! Mail, Gmail
  • Apple Mail (iPhone, iPad, Macbook, MacbookPro)
  • BlackBerry mail client
  • Nokia/Symbian client (Nokia)

To bad Mutt isn't in this list.

First thing I wondered when I read this is: HP ePrint: What is wrong with lpr and lp and RFC 1179?

I think I jump to the disable section right away and I'm glad my printer doesn't support it

On the German eBay i found a lot of these.

I had heard of it before, but someway it has slipped my mind. But purely by accident I came across BrainFuck again.

Maybe a nice project for a sunny afternoon.

Donating blood 100 times

2009-05-15 (21) by Ton Kersten, tagged as news

Being a blood donor since 1982 I have been donating blood on a regular basis. Today I reached the milestone, that I'm very happy about. I donated blood 100 times. This equals 50 litres of blood in total.

I would like to urge you all: Please give. It doesn't cost you anything but a little time and you help a lot of people. So: Give
