I enjoyed this immensely, but it is about one in the morning and I have been up since about five cleaning house and preparing for my next Great Adventure.


I am probably punchy.

Training Neural Networks to Write Bach in a Day! March 24, 2017

Fascinating bit of video here as Our Hero (not me, in this case) takes Bach (and later Mozart) MIDI files, creates an 88-character ASCII-character alphabet from them and trains a Recurrent Neural Network to output similar sequences.

The results (and a lot of the process) is shown in the video above.  Take your time and watch the whole thing; I wonder how long he would have to train the RNN to start outputting Baroque Muzak continually?

I would like to point out that Star Trek has so influenced culture that the United Federation of Planets is likely to happen any time now…we just need more planets.  We already have Majel Barret’s voice phonemes.  Now we need Google to sync up, a bit better response to voice meaning (the voice vector thing should help), a truthiness evaluator and bingo! Star Trek in your phone/home/office/laboratory/dungeon/whatever.

Amazon Moto G Play Phone January 19, 2017

People in the know (i. e., my readers) are aware that I take my phones seriously, and have for three smart phones now. Well, smart-enough phones, I guess.  I mean I had an HTC 8125 ancient creaking phone with one of Microsoft’s many, many failed phone operating systems (are they really up to FOUR commercially-failed systems, and about to go for FIVE?), which did some things I needed in a phone: calculator (never used it, but could have), texting (would have used it but did not…not sure that it could, now that I think on it), took [execrable] photographs (look back in this blog far enough and you will find them, along with scathing reviews of the image quality) but at least ran the flash card app I wrote for it, among others (my writing them would not have been necessary if MS has anything like an app store.  Just sayin’), and played my beloved audio books during my [endless] commute.1

Still, it was not the optimum device.  My next phone (Samsung Galaxy S3 i9250) was a considerable improvement, in that the camera focused closely enough to copy text.  It ran Android apps mostly without complaint (even ones I had written myself), texted my children and played Bluetooth music and audio books without complaint, even after having survived several cracked glass incidents (to be fair, I never did repair the glass.  It looked like a vandalized cathedral when it finally died). It was a vast improvement, and I cried bitter tears indeed2 when it suddenly stopped letting me make telephone calls.

Now I have the aforementioned Amazon Moto G Play phone, and I must say it is an improvement on my previous experiences (except for the annoying notifications.  How the #$%^&* do I turn them off?) in speed, in reception and in sound clarity (although not volume).  The camera is much better (see recent postings about the weather, blue jay invasion, etc.) and the Android version is 6.0, which is 1.7 better than previous.  And it was cheap: $99 for the phone with advertising, $149 without.  I have been unable to figure out how to replace the bootloader to get rid of the advertisements (which would violate my agreement and would be Bad And Wrong), but it works so well I don’t care at all.

EXCITING, HORRIBLE UPDATE: can’t root the phone to use adb wireless.  This is totally bogus.

1Not sure that’s the longest run-on sentence I have ever written, but Baron Bulwer-Lytton must feel somewhat threatened in his cozy grave.

2Mostly because I had spent a fortune on it.  Don’t fear; this story DOES have a happy ending.

It’s been a banner week for science geeks, nerds, and squints. The locked-in lady gets to at least shout from her prison quietlyGoogle has radar sensitive enough to not only find objects but identify them by their radar signature and perovskite is once again breaking solar-conversion efficiency records.

Ordinarily I would give you a breakdown of each of these nifty developments, but more are coming and I may want to return to these later when I am not pressed for time.  Follow the links above; there are others as well that you will find more well constructed than my chicken scratchings, I’m sure.

Brain-Computer Interface Now in Use at Home!!! November 15, 2016

A 58-year-old woman (“HB”) with ALS has had a functioning brain-computer interface (BCI) for a while now, and is able to communicate (slowly) with the outside world. She was facing total lock-in Real Soon Now, so any device which offers communication ability is welcome.

What it is:

A diagram illustrating the setup and use of the ECoG implant.

Electrode strips at the top laid across her brain like band-aids read faint electrical signals.  With training HB was able to “type” fairly quickly (words per minute, but still).  More work remains to be done on the interfacing software (I am imagining more inputs and a neural network to interpret her thoughts more and more efficiently), and HB is ecstatic to have a way t live in the world.  She would like to use the interface to control a wheelchair, for example, but that is a ways off.

A friend gave this to my wife today (the egg mold, not the scotch). I couldn’t wait for breakfast to enjoy it (hence the scotch).  Turns out you can get them sent to your house by tomorrow if you have Amazon Prime.  Hurry up! We can all commune tomorrow morning with pirate eggs.

Better Neutrino Detection Through Beta Decay November 9, 2016

Posted by stuffilikenet in Awesome, Geek Stuff, Japan, Science, Toys.
add a comment

Once upon a time scientists studying the sun couldn’t have the faintest idea of the internal activity of the Sun. One bright (see what I did there) scientist realized that monitoring neutrinos, the massless, chargeless, non-interacting particles that zip through the universe barely interacting with anything at all, might give a useful clue to the machinations therein.  I mean, they knew neutrinos are part of the solar flux,so it’s just a matter of detecting massless, chargeless, non-interacting particles.

Oh, crap.

Well, luckily neutrinos do not remain neutrinos forever; they decay into detectable particles…eventually.  Not often to be sure, as billions pass through a square centimeter every second without leaving any decay particles. Those decay particles can be detected with rather elaborate photomultipliers in a huge cavern in Japan somewhere: “It consists of a tank filled with 50,000 tons of ultra-pure water, surrounded by about 13,000 photo-multiplier tubes. If a neutrino enters the water and interacts with electrons or nuclei there, it results in a charged particle that moves faster than the speed of light in water. This leads to an optical shock wave, a cone of light called Cherenkov radiation. This light is projected onto the wall of the tank and recorded by the photomultiplier tubes.1“ Despite the heavy hardware only a few thousand are detected every year, which should tell you something about the likelihood of a decay event…not very damn likely.

Thing is, the theoretical number and the actual number didn’t match; the experimental result was one-third of theoretical, indicating something must be wrong with the theoretical understanding, or the experiment is crap. It turned out that neutrinos oscillate among three forms (electron, muon and tau) and detectors were primarily sensitive to only electron neutrinos.

Here’s where science gets really intricate; pour another shot and I’ll tell you why. In a distantly-related field, other scientists observed variations in the rate of beta decay of radioactive elements.  Once again, either the data is crap or the theory, and the theory says the decay rate should be constant.  Looking at the data over time, they found that the beta-decay rate matched the neutrino data, indicating a one-month oscillation attributable to solar radiation. Many now believe that neutrino emissions from the Sun are somehow affecting beta decay.

If that’s not strange enough for you then feature this: the same guys who figured this out are going to use beta-decay experiments here on Earth to monitor massless, chargeless, non-interacting neutrinos, and thereby the Sun.

You heard me. Watch the video and be amazed.

The researchers think it could be ready for human trials by the end of the decade.

If it sounds familiar, it might be because Star Trek thought of it first:

The Homemade Muon Detector October 15, 2016

Dazzling in complexity, the little chart above details the fate of cosmic rays (high-energy protons hurtled from the sun) which impact our atmosphere, leaving a byzantine collection of particles and EM emissions.  Some of these suckers are relatively easy to detect; the muon possibly the easiest.  Scientists studying the output of our sun can use more information about cosmic ray bombardment and an array of muon detectors would be really useful for this as muons (and other particles) are generated within a cone-shaped shower, with all particles staying within about 1 degree of the primary particle’s path.

Enter Spencer Axani, doctoral student at Massachusetts Institute of Technology who has whomped one up for a mere hundred bucks, and published a paper with detailed construction plans (no Instructables project yet, however.  I checked):


Straightforward as heck, a plastic brick and a photomultiplier tube are locked up in a light-tight box.  Muons hit the brick, generate a photon on decay and the photomultiplier generates enough juice to tell there’s been an event. An Arduino is used (yes, an Arduino) as a peak detector and a Python script crunches the time-stamped data for delivery to a PC.

He took it around Fermilab to test it out in Real Life:


Neat-o, right?

An Electromagnetic Pulse (EMP) generator can overload various kinds of circuitry, causing all sorts of merry havoc among the pinks.  You can make a little baby one and overload poorly-protected circuits up close, although a hammer is more certain to succeed.

Universal Molecular Diagnostics by Affinity October 10, 2016

Rice University researchers have invented a technology that could potentially identify hundreds of bacterial pathogens simply, quickly and at low cost using a single set of random DNA probes. Richard Baraniuk, Amirali Aghazadeh and Rebekah Drezek whomped up a batch of five random probes and used them to identify 11 known strains of bacteria, providing a genomic-based test for identity of pathogens.  This is a big deal because usually each species required its own DNA probe.

Their new study includes several computer simulations, including one that shows how a random selection of five probes can identify 40 different strains of bacteria, and another that demonstrates how the system can accurately differentiate between 24 different species of Staphylococcus.

Rather than identifying a target strain based on a 100 percent match with a specific probe, Rice’s system tests how well the target DNA binds with several different random segments of complementary DNA. UMD uses a mathematical technique called compressive sensing, which was pioneered in the field of digital signal processing. With compressive sensing, the disease DNA need not bind with 100 percent of the probes. Instead, the new system measures how well the disease DNA binds with each of the random probes and creates a specific binding profile for the test organism. It then uses deductive reasoning to determine whether that profile matches the profile of any known pathogens.

With larger numbers of probes, it works even better:

No special hardware is required for this approach, other than the tried and true PCR with which we have become familiar over the last twenty years (thank you, Kary Mullis and LSD). The special sauce is the computer code which figures out the relative affinities.  This can be made available everywhere pretty cheaply, versus specialized DNA probes which require expensive facilities and a lot more regulatory testing.

Jeff Bezos tweeted this picture of his boots and booze after completing a bucket of milestones in space exploration:

  1. Five flights of the same, reusable Blue Origin spacecraft within a year
  2. Separation of booster rocket and capsule with safe return for both
  3. Restart of booster rocket at only 3300 feet and safe return
  4. Safe return of capsule with one deliberately failed parachute.

The boots say “step by step, ferociously” in Latin. 

Smug and pretentious.  And well deserved.
