Voyager needs a FORTRAN programmer.  "It was state of the art in 1975, but that's basically 40 years old if you want to think of it that way," Suzanne Dodd, program manager for the Voyager program, said.

 _[UPDATE (from the article)] The Voyager team is not yet hiring anybody to fulfill the role. The retirement is not anticipated until next year. "I go down the hallway and I meet people and I say, 'Wow, Voyager was the best project I've ever worked on. I wish I could get back on it again.' [she] said.​_

What does your Windows command-line setup look like?

To familiarise myself with the dev experience on Windows, I've been trying to replicate the setup I've got on Mac there. Something that gives me iTerm 2 + Dotfiles + Bash  + Unix utils and maybe some Git helpers and a Homebrew equivalent.

So far I've got Cmder (~ConEmu fork, Msysgit, Clink) to boost my shell, Cygwin, PoshGit and a PowerShell profile with some shell/Doskey aliases in there. I've also got Chocolatey. Some of the questions I find myself a little uncertain about are:

- What are other folks using? I'm really interested in how you tackle aliases as there seem to be a ton of ways of handling them.
- Is there a community like for Windows PowerShell aliases?
- Does anyone have a sweet setup for sharing aliases between multiple platforms? (Win/Mac/Linux).
- Any other tips worth knowing? I've literally just been trying Windows again over a few weeks so there's probably tons I'm missing.

Thanks all!

Virus to fight cancer receives FDA approval, motorcycle-riding robot hits 100 kmph (no bike mods required) and more great news from this week's +SciTech Digest by +Mark Bruce.  

#sciencesunday    #science   #technology  #stem #robotics #medicine
SciTech #ScienceSunday Digest - 44/2015.
Permalink here: 

Computational acoustics, BCIs and touch, Activating membrane proteins, Superconductivity, Bike riding robot, Virus vs cancer, Rejuvenate immune system, Printing hair, Glass like steel, Triggering hair regrowth. 

1. Acoustic Holograms for Levitation
A phased array of 20 by 20 ultrasonic transducers with programmable relative phase modulation is capable of generating controlled, dynamic acoustic three dimensional structures in air, with one of the key innovations being that you no longer need an identical array opposite to the first. These invisible structures made of sound can be used to pick up and move individual objects around, independently move separate objects around and interact with each other and can be thought of an acoustic tractor beams. Applying the array to the surface of the body would mean  picking up and moving things inside the body some depth below. No doubt there are lots of applications people haven’t even begun to think of. Computational acoustics was a doubly-interesting field this week with new algorithms able to optimise the specific vibrational acoustic design of custom 3D printed objects, demonstrated by creating a xylophone whose keys were different-shaped animals and yet produced the correct notes when struck, leading to promising sound enhancement or dampening applications in industry or consumer goods. 

2. BCIs and Prosthetic Sense of Touch
Yet more work (with the help of DARPA) and progress on the way to helping amputees experience a full range of touch sensations from their prosthetic limbs With the help of electrode arrays implanted into the somatosensory cortex of monkeys the group measured many parameters and “just noticeable differences” and developed models able to induce a wide range of sensory experiences and near to real algorithms that work to provide nuanced experiences to humans. In related news we hear about a BCI allowing a patient to control a Nexus 9 tablet with her thoughts to communicate and perform google searches

3. Activating Any Membrane Protein with Light
Using newly developed SNAP-tag technology cellular membrane proteins can be attached to linker molecules and chemical assemblies that stably switch bonds and isoforms when exposed to light, which can forcibly switch important membrane proteins on and off Seems this group has been developing the technology for a while now. In this demonstration they used a type of common G-protein-coupled-receptor to show it worked, but this is a modular tool that can be attached to any such membrane receptor. Similar to optogenetics this could be applied to study and more subtly control neurons or any type of cell in certain ways. For example, linked to certain receptors the activation of light could induce drug effects. 

4. Advances in Superconductivity
A new unexpected phase of matter was discovered in which the order is not described by scalar or vector properties but by more complex multi-polar orderings that involve magnetic quadrupoles The material that exhibited this property was strontium-iridium oxide, which has structural similarities to copper-oxide-based “high-temperature” superconductors, and so this work helps to shed theoretical and experimental light on high temperature superconductivity in general, underlining the importance of uncovering new natural phenomena like this. In related news, the “conventional” superconductor hydrogen sulfide has been confirmed to superconduct up to a scorching minus 70 degrees C when subjected to extreme pressures

5. Motorbike Riding Robot
In a surprise announcement this week Yamaha showed off the robot, called Motobot, that it has been developing that rides conventional motorcycles just like a human does Motobot currently rides motorcycles at 100 kmph, but by 2017 they hope to have developed it to a stage where it can ride at 200 kmph and complete race circuits as well as or better than the best human riders. I’d certainly watch a better-than-human bot race. In news related to robots able to autonomously travel and navigate environments we have robots relocalising and 3D mapping environments for better autonomous navigation, and robots being given simulations of neuronal place and grid cells to help with better navigation

6. FDA Approves Virus vs Cancer
For the first time a virus engineered to help the body remove cancer cells has been granted approval by the FDA, initially for treating advanced melanoma This is a trigger event for the field, which should boom over coming years with many other oncolytic viruses undergoing clinical trials against different types of cancers. This particular virus can enter healthy cells but is unable to replicate. When it enters cancer cells it produces proteins that target the cell for destruction by the immune system and activate an immune response against those cells elsewhere in the body. Future improvements should crack the systemic delivery problem. 

7. Multiple Methods to Rejuvenate the Immune System
FightAging! was on a roll this week with immune rejuvenation. First, resupplying young, engraftable thymic epithelial cells to an aged or defective thymus leads to thymic growth and increased T cell production and should lead to improved immune function Second, thymic epithelial cells can be boosted by increasing activity levels of a single gene and so rejuvenate the thymus for improved function Third, specific cell-surface markers for exhausted T cells have been identified, which should allow targeted cell destruction to remove these defective cells so new ones can take their place Finally, a currently approved immunomodulatory drug (for asthma / allergy) appears to rejuvenate old rat brains and boost neuron growth

8. 3D Printing Soft Strands & Hair
While at first glance this might appear to be a trivial development, the ability to reliably and precisely print (with very basic 3D printers) soft strands and artificial “hair” is pretty cool and useful The embedded video is worth a watch. Toys are the most trivial example of course, and probably custom wigs in future, but this will end up being great for at-home printing of toothbrushes, paint brushes, and washing scourers, while the ability to weave it means you can probably make custom ropes and twine using the method. 

9. Glass Nearly as Strong as Steel
Transparent “ultra” glass can now be made by creating a 50/50 alumina/glass mixture via a novel containerless processing method that involves synthesising the mixture in air The material is transparent and possesses a Young’s modulus comparable to steel and iron. While stronger windows in buildings and cars (military?) and also computers and phones are obvious and desirable applications, such a material might be formed into raw structural engineering components to enable entirely different and never-before-possible buildings to be constructed. 

10. Restarting Hair Regrowth
Two drugs that already have regulatory approval have been shown to be effective in kickstarting and boosting hair regrowth for baldness applications While initially testing autoimmune causes of baldness, the team discovered that the drugs inhibit a specific protein in hair follicles, serving to reawaken hair follicles from a resting state, with bald mice regrowing hair over a 1- day period, with near-complete regrowth of hair after 3 weeks. Human studies and clinical trials will be the next step.

This is Git. It tracks collaborative work on projects through a beautiful distributed graph theory tree model....  :)

#xkcd #git #versioncontrol #computerscience #code   
Spot on, considering I finally switched to git from svn only 2 months ago for all our projects.

And the caption: If that doesn't fix it, git.txt contains the phone number of a friend of mine who understands git. Just wait through a few minutes of 'It's really pretty simple, just think of branches as...' and eventually you'll learn the commands that will fix everything.

We have so many powerful tools at hand, but trouble can result from feeling a need to learn the tool without really understanding the problems the tool solves for us.

California is dry, but not as dry as Mars. Sometimes though, the two places look eerily similar. Take our quiz to see if you can tell them apart.

Interesting discussion on recent brain research - includes a discussion on the many factors that contributed to the fortuitous rise of our intelligence.

Quanta Discusses Recent Brain Research

Many of you already read Quanta but this is another excellent article that I thought deserved a summary share, How Humans Evolved Supersized Brains. The article delves into the ongoing puzzle as to why and how human brains came to be so big and powerful; why over less than 3 million years they quadrupled in size from 350g to 1,300g, when primates took 60 million years to reach 350g brains in the first place. 

Some points of interest:

➤ New techniques to dissolve brains and extract and count cell nuclei give much more accurate cell counts for brains and, for example, show that larger brains do not always have more neurons and neuronal distribution is often different. The human brain has more neurons in the cerebral cortex than any other animal. 

➤ While an elephant has a brain 2.5 times as large as a human (2.8kg vs 1.2kg), the cerebral cortex of the human brain has 3 times as many neurons (16.3 billion vs 5.6 billion). This is the first time I’ve come across this fact. 

➤ While the human brain as about 86 billion neurons, 69 billion are in the cerebellum and only 16 billion are in the cerebral cortex for high-order intelligence and reasoning. To me this suggests a sort of computational overhang with regard to developing neuromorphic AI: you won’t need hardware that can replicate 86 billion neurons, but only 20% of that - so ~2.5 doublings or ~5 years earlier than expected. 

➤ Human brain makes up 2% of body mass but consumes 20% of total energy, whereas a chimpanzee requires only half that. 
Analysis of cellular glucose-importing genes in the brain and muscle reveals that such genes are 3.2 times more active in human brains compared to chimp brains, but 1.6 times more active in chimp muscles compared to human muscles, and identically active in the respective livers. Human regulatory sequences for these genes show signs of accelerated evolution. Accounting for size and weight, chimp muscles are about twice as strong as humans. 

➤ Key regulatory sequences active in brain development were taken from humans and chimps and introduced into mice: mice with the human version developed brains 12% larger and had cells that divide and multiply in 9 hours instead of 12. 

Goldilocks Factors for Human Intelligence

The development of human intelligence appears dependent on a fortuitous confluence of many different factors:

➤ Development of bipedalism to free up hands for tool-making, at the expense of slower movement compared to predators. 

➤ Development fire-building and hunting to source easier-to-digest and higher-quality foods due to energy allocation away from gut and muscles.

➤ Development of extreme manual dexterity. 

➤ Development of vocal tract capable of complex communication at the expense of choking hazards. 

➤ Development of extremely dense and dangerously energy hungry neural cortex at the expense of muscle power.  

➤ Development of extreme sociality to facilitate large, stable groups of individuals, requiring a long childhood and retention of play and curiosity with age, at the expense of more than a decade of youthful defenselessness. 

➤ I think the general process of neoteny, the retention of juvenile characteristics into adulthood is important here in general to facilitate a great many of these factors. 

➤ A complex environment nonetheless conducive to the survival of such a physically weak animal is also important. 

When considering the development of intelligence not only on Earth, but also elsewhere in the Universe, these are all important factors that should feed into and influence the Drake Equation and Fermi Paradox. There are a lot of subtle factors that were required to be present in just the right way at just the right time for human intelligence to begin to emerge and develop; a lot of luck seems to have been involved. Primate brains were quite content to remain at 350g for 60 million years, not to mention the dinosaur brains before them that were content to remain smaller for a much longer period of time. I hope as we learn more about these different factors we gain a clearer idea of how astronomically improbable the development of our intelligence was and so a greater degree of confidence that the Great Filter is behind us.

The note about fire-building and hunting tracks with sociologist Richard Wrangham's book, Catching Fire: How Cooking Made Us Human, in which he suggests that fire turned us into communal animals rather than grazers, and also that cooking, while stripping protein from our food, makes the remainder more easily accessible/digestible ... and that kickstarted our cognitive development.

Whales and dolphins are placental mammals, like humans. If you go back in our respective family trees about 100 million years, you'll find our common ancestor [1].  With our knowledge of her descendants, we can predict her genomic sequence with high accuracy [2].

Practical considerations for gathering name information on forms.

Why "first name / last name" doesn't cut it.

#enhancing #userexperience #webdesign
How to treat people's names in your systems, while being mindful of the differences in naming conventions around the world.

Splitting up names into first name, middle name, family name etc. doesn't always make sense when dealing with people around the world. It's smarter to ask for a formal (legal) name, and an informal (preferred) name for addressing them in things like emails or addressing them in person. If you send communications to them in their native language, you may also want to collect the name in their native script as well.

Don't assume that their names can be expressed in just the English alphabet either. UTF-8 support is ideal, but you could also just allow accented characters and punctuations such as hyphens, apostrophes and exclamation marks at the minimum.

Via +Jonathon Fowler 
W3C i18n article: How do people's names differ around the world, and what are the implications of those differences on the design of forms, databases, ontologies, etc. for the Web?

A Few Favorite Quotes

"A ship in harbor is safe. But that is not what ships are for." 
- Rear Admiral (and Computer Scientist) Grace Hopper

"Do not believe in anything simply because you have heard it. Do not believe in anything simply because it is spoken and rumored by many. Do not believe in anything simply because it is found written in your religious books. Do not believe in anything merely on the authority of your teachers and elders. Do not believe in traditions because they have been handed down for many generations. But after observation and analysis, when you find that anything agrees with reason and is conducive to the good and benefit of one and all, then accept it and live up to it." 
- Gautama Buddha

"There should be no boundary to human endeavor."
- Stephen Hawking

"My undergraduate experience convinced me that I was not smart enough to be a physicist, and that computers were quite neat."
- Dennis Ritchie
“The master in the art of living makes little distinction between his work and his play, his labor and his leisure, his mind and his body, his information and his recreation, his love and his religion. He hardly knows which is which. He simply pursues his vision of excellence at whatever he does, leaving others to decide whether he is working or playing. To him he's always doing both. ” ― James A. Michener
