Mapfactor Navigator: Convert you POIs

I am currently switching to Mapfactor Navigator mainly to use now also offline Open Street Maps.
The main problem is to get all those old waypoints converted. Unfortunately it is confusing what developers but users are reporting on different forums. MN obviously used different tools at different times and even different directories.

Before you start, get the most recent version Continue reading


Warum Radhelmpflicht mehr schadet als nützt

Es ist leider öfters so, dass sich der gesunde Menschenverstand irrt. Vordergründige Logik ist eben doch nur vordergründig. Was habe ich nicht alles an Unsinn gelesen zu dem Thema Radhelm im Zusammenhang  mit dem unsäglichen OLG Schleswig Urteil, das der BGH glücklicherweise nun aufgehoben hat. Unter anderem seien auch die Zahl der Kopfverletzungen in Neuseeland zurückgegangen. Logisch eigentlich, wenn niemand mehr Rad fährt… Im Original liest sich das so

The New Zealand helmet law (all ages) came into effect on 1 January 1994. It followed Australian helmet laws, introduced in 1990–1992. Pre-law (in 1990) cyclist deaths were nearly a quarter of pedestrians in number, but in 2006–09, the equivalent figure was near to 50% when adjusted for changes to hours cycled and walked. From 1988–91 to 2003–07, cyclists’ overall injury rate per hour increased by 20%. Dr Hillman, from the UK’s Policy Studies Institute, calculated that life years gained by cycling outweighed life years lost in accidents by 20 times. For the period 1989–1990 to 2006–2009, New Zealand survey data showed that average hours cycled per person reduced by 51%. This evaluation finds the helmet law has failed in aspects of promoting cycling, safety, health, accident compensation, environmental issues and civil liberties.

Vielleicht nochmal zum Mitschreiben: Radfahren führt zu einer sehr viel höheren Lebenserwartung, selbst unvermeidliche Unfälle eingerechnet. Die Helmpflicht hat die Häufigkeit des Radfahrens halbiert, damit natürlich einige Kopfverletzungen vermieden, aber vor allem die ansonsten durch das Radfahren gewonnene Lebenszeit halbiert.
Was soll man nur zu dem Thema noch sagen wo Einstein schon alles gesagt hat? Ansonsten gibt es vernünftige Kommentare auf Fahradhelm kurz & bündig und Sinn und Nutzen von Fahrradhelmen Das nicht ganz unlogische Fazit – ich bin gegen Helmpflicht aber fahre meistens mit Helm. Ach so, und nirgendwo sind die Menschen so dick wie in Australien:

Australia: the world’s fattest nation. A public health crisis
Australia is now the fattest nation in the world, with more than 9 million adults rated as obese or overweight. (Stewart et al, 2008)
It is predicted that this will lead to 123,000 premature deaths over the next two decades and that an extra 700,000 people will be admitted to hospital for heart attacks, strokes and blood clots caused by excess weight. The costs will exceed AUD 6 billion.

Snow (den) ball effect

Hello Matthias,
As it turns out, many people were listening when Edward Snowden mentioned SpiderOak. As a result, we’re seeing the highest rate of signups in our history. This has caused a dramatic increase in server load and customer inquiries. It’s been all hands on deck, around the clock to deliver the kind of service and response we feel is appropriate for such an occasion. By way of managing expectation, we plan to be fully adjusted within the week.

With ‘Zero-Knowledge’,

I can confirm, that SpiderOak is working well on several platforms at least for internal purposes. The only function that I missed so far is the data upload in the Android client.

Overdiagnosis is harming patients

It’s the downside of always improved diagnostic procedures. With science progress and more information available, many information pieces are unvalidated and have a duobtful prognostic and therapeutic value. They even harm patients, possibly by further and unnnecesssary (dangerous) procedures but also increased insurance rates. The problem has been excellently described 2 years ago by Ray Moynihan, Jenny Doust, and David Henry in a BMJ.

Only recently I learned that there is now even a conference series how top stop harming the healthy. An own pubmed analysis showed zero interest in 1970, then gradually increasing until 2010 up to about 100 papers/year while now doubling in the last 3 years.
