System for Approving New Medical Options Needs Improvement
Posted on December 31, 2012 Comments (0)
…
Without a rigorous, data-driven context, medicine’s expensive traditions and hunch-based treatments threaten to bankrupt us. “People say that we shouldn’t delay science; people are dying; we should get new treatments out there. I do not feel the pressure to do that until we have solid evidence,” Ioannidis asserts. “The resources many procedures draw are enormous.” And that leaves insufficient funds for the prevention plans and treatments we know actually work.
I have written about the problems with our health care research system several times. The existing system is in need of improvement and is made much worse by the general state of the broken health care system in the USA. Dr. John P.A. Ioannidis, the focus of the article, is doing fantastic work in this area.

Make Crosswalks More Visible

Good simple idea. And then executed well – for nighttime at least. Crosswalk lights up when in use giving drivers a more visible clue to stop.

Circumhorizontal Arcs – Fire Rainbows – Cloud Rainbows

Fire Rainbow, Johor Bahru by John Hunter
Yesterday afternoon I spotted this odd, colorful, spectrum seemingly in a cloud in Johor Bahru, Malaysia. The colors are similar to a rainbow but the prism effect takes on a bit different form than a rainbow as I learned with a bit of searching online. I added a short post to this blog, about the phenomenon a few years ago.

Johor Bahru under a large cloud which is topped with a fire rainbow.
A circumhorizontal arc is an optical phenomenon – an ice-halo formed by plate-shaped ice crystals in high level cirrus clouds. They are also known as “fire rainbows,” if the cloud is at the right angle to the sun, the crystals will refract the sunlight just as when rainbow is created.
Working as a Software Developer
Posted on December 17, 2012 Comments (11)
For most of my career I have been focused on management improvement – helping organizations improve results. Technology plays a big role in that and along the way I found myself becoming a programer for a while; and then a software development program manager. This is a good post on working as a software developer:
…
Write for people first, computer second. The code you write will be read many times in the future (by you, or another developer). The computer doesn’t care how the code is written, so make it as easy as possible to understand for the next person that has to read it. A corollary to this is: don’t be too clever. It’s better to be clear than to be clever.
When there is a compelling need to write for the computer first and people second make sure to document that code well. For example, some code that is extremely dense and complex and confusing but greatly enhances the efficiency of a critical area of code.
I recently wrote a book, Management Matters: Building Enterprise Capability. There are many great things about a career in software development. It certainly is also challenging and not for someone looking for the easiest career but I have seem a higher percentage of happy software developers than I have seen in any other discipline.

Promoting Innovation in Sierra Leone

Another inspirational kid that shows that the potential for human good is much greater than the talking heads and politicians that litter the TV screen so often.
In the video Kelvin says, “That is my aim: to Promote Innovation in Seira Leone, among young people.” See another video as Kelvin explains his homemade battery.
Support these young engineers in Sierra Leone via innovate Salone.

Arduino Introduction Video Tutorial
Posted on December 5, 2012 Comments (0)
Arduino is a very cool open source programable hardware engineering initiative. It is great for kids and adults who like to learn and create electronic devices. The Arduino Starter Kit is a great education gift for those interested in such things.
The video explains how to build a basic circuit with the Arduino board, and how to use each of the basic components such as LEDs, switches, and resistors. See more videos on related topics. Massimo Banzi, the co-creator and CEO of Arduino, and seen in the videos, also has a book: Getting Started with Arduino.

Cancer Risks From Our Food

Pretty much everything you eat is associated with cancer. Don’t worry about it. by Sarah Kliff
…
The vast majority of those studies, Schoenfeld and Ioannidis found, showed really weak associations between the ingredient at hand and cancer risk. A full 80 percent of the studies had shown statistical relationships that were “weak or nominally significant,” as measured by the study’s P-values. Seventy-five percent of the studies purporting to show a higher cancer risk fell into this category, as did 76 percent of those showing a lower cancer risk.
Sadly the evidence is often not very compelling but creates uncertainly in the public. Poorly communicated results and scientific illiteracy (both from publishers and the public) leads to more confusion than is necessary. Even with well done studies, good communication and a scientifically literate population nutrition and human health conclusion are more often questionable than they are clear.
