OLED displays on the way

I remember the first time I saw a digital picture frame, an electronically driven screen that can be loaded with digital images and be made to cycle images over time. The early ones were bulky and didn't have much memory for images, more recent devices allow wireless delivery of the images but are battery hogs. I remember in the early days thinking it was an interesting technology but would really take off after one important event. Namely, the creation of a truly energy efficient display technology that provided a realistic image without the need for the backlighting of all the LCD driven units on the market.

That technology has been in the labs for quite some time and it is poised to be released on the masses , it is called OLED (Organic Light Emmitting Diode/Display). An OLED display combines the advantages of a CRT and an LCD, it has amazingly high dynamic range and a wide gamut (roughly the subtly of tones that can be rendered for each color channel) and is incredibly power efficient. It also adds something to the mix that Plasma, CRT's nor LCD's can do, an OLED display can be flexible. Take a look at this video and this video from youtube. As a sign that Sony is serious about bringing this technology to light last night at the Iron Man premiere here in NYC, one of the commercials was a rather interesting advertisement for the new OLED display that is going on sale this year.

OLED will allow the digital picture frame market to blossom by providing true "any angle" viewing thanks to its lack of the angle of view constraints of LCD's and the fact that the light comes from the pixels and not from a backlight. The energy efficiency will allow wireless devices to run for significantly longer periods of time as well. Beyond this, the resolution advantages and the ability to create transparent and flexible displays will really open up the display market. So any current method of displaying imagery will be made more efficient through the use of the coming OLED displays. Imagine having these displays all over your wall and tied to your home computer systems, any OLED embedded surface can then be used to view data, images what have you. As an undergrad EE student I remember reading an engineering trade journal that covered the then first optical digital video disk device (we know it today as DVD) the prototype was about as big as a washing machine, after reading that article I resigned not to buy another VCR (I had only purchased one up to that time around 1988) as I waited for DVD, which finally debuted almost 10 years later for the masses. The cost reduction over that time for the technology is going to hit OLED and thanks to the elegence of the technology will allow it to gain amazing ubiquity in a very short time. So I am putting a bet on a really explosive market in OLED driven display technologies.

Highly targeted Cpg vaccine immunotherapy for a range of cancer


This will surely go down as a seminal advance in cancer therapy. It reads like magic:

So this new approach looks for the specific proteins that are associated with a given tumors resistance to attack by the body's T cells, it then adjusts those T cells to be hyper sensitive to the specific oncogenic proteins targeted. These cells become essentially The Terminator​ T cells in the specific tumor AND have the multiplied effect of traveling along the immune pathway of spreading that the cancer many have metastasized. This is huge squared because it means you can essentially use targeting one tumor to identify and eliminate distal tumors that you many not even realize exist.

This allows the therapy for treating cancer to, for the first time; end the "wack a mole" problem that has frustrated traditional shot gun methods of treatment involving radiation and chemotherapy ...which by their nature unfortunately damage parts of the body that are not cancer laden but …

Engineers versus Programmers

I have found as more non formally trained people enter the coding space, the quality of code that results varies in an interesting way.

The formalities of learning to code in a structured course at University involve often strong focus on "correctness" and efficiency in the form of big O representations for the algorithms created.

Much less focus tends to be placed on what I'll call practical programming, which is the type of code that engineers (note I didn't use "programmers" on purpose) must learn to write.

Programmers are what Universities create, students that can take a defined development environment and within in write an algorithm for computing some sequence or traversing a tree or encoding and decoding a string. Efficiency and invariant rules are guiding development missions. Execution time for creating the solution is often a week or more depending on the professor and their style of teaching code and giving out problems. This type of coding is devo…

First *extra Galactic* planetary scale bodies observed

This headline

So every so often I see a story that has me sitting at the keyboard for a few seconds...actually trying to make sure the story is not some kind of satire site because the headline reads immediately a nonsense.
This headline did just that.
So I proceeded to frantically click through and it appears it was a valid news item from a valid news source and my jaw hit the floor.
Many of you know that we've been finding new planets outside of our solar system for about 25 years now.
In fact the Kepler satellite and other ground observatories have been accelerating their rate of extra-solar planet discoveries in the last few years but those planets are all within our galaxy the Milky Way.
The three major methods used to detect the bulk of planets thus far are wobble detection, radial transit and this method micro lensing which relies on a gravitational effect that was predicted by Einstein in his general theory of relativity exactly 103 years ago.
