New Scientist reports Brain barrier opened for first time to treat cancer. "For the first time, doctors have opened and closed the brain's protector – the blood-brain barrier – on demand. The breakthrough will allow drugs to reach diseased areas of the brain that are otherwise out of bounds. Ultimately, it could make it easier to treat conditions such as Alzheimer's and brain cancer."

So lots of upgrades lately. iOS 8.1 came out and I installed on the iPhone 5 without difficultly. I still haven't upgraded the iPad 2 to iOS 8 as I understand it just slows to a crawl and 8.1 isn't any better. I'll just wait til I get a new iPad Air 2 which I'll do shortly.
I upgrade first the old MacBook Pro and then the iMac to Yosemite. It mostly went well. The MBP was easy and all my apps seemed to work so I did the iMac today. I started the download last night and was crawling for a while (5+ days to go for several hours) but then it started to come down quickly and was done after a few hours. There are a number of forum threads I found that said that changing DNS servers helped, but it doesn't really. (In fact I read a couple of years ago that if you change from your ISPs DNS servers to Google's or OpenDNS or something that your location information is lost and CDNs don't know which server is closest to you. I don't know if that's true, but my experience is that using FiOS DNS is at least as good as using others.).
Once it was downloaded the installer started. I quit it and made a bootable USB stick. This morning I did the install and it went pretty quickly. Then I started going through the new features, via a few articles I had saved. The only annoying thing I fixed was to Reduce transparency in the Accessibility System Preferences. I don't know why anyone would want it on.
I still have not enabled iCloud Drive because my iPad 2 running iOS 7 can't use it. But that shouldn't be much of a problem for while. Update: It turns out it breaks Tweetbot's sync'ing. It looks like there is not longer an iCloud "Documents & Data" setting, there's just iCloud Drive, so they probably have no other way to share data.
I really wanted to try some of the Continuity features that connect the mac to the phone. There were three. First I got AirDrop working. I find it's a little flakey. I enable it on both and turn on the phone but if I open the Finder to AirDrop it doesn't show me (and when it does it's just my picture with my name, not the name of my iPhone. I sometimes can use AirDrop from Safari's share menu and send it to my phone, but not always.
The next thing was Handoff. This didn't work until I rebooted my iMac. When it does work I can see the last app you've used on one device on the other device. I've used Handoff with Safari and Mail both ways and it's pretty slick.
The last one was Phone calls and that was a bear. Basically the Mac can act like a speaker phone for your iPhone and you're supposed to be able to start calls from the mac (in the old days you do this with a bluetooth connection, but that hasn't worked for a while). I kept getting an error that it wasn't working and to check that both devices were on the same wifi network and using the same iCloud account. They were. There's a setting to enable it in FaceTime and that was on too. I called AppleCare. I got a woman who didn't know much but was nice enough. She talked to second level support and left me on hold for a very long time and we didn't come to any conclusion (other than you didn't need to bluetooth pair your iPhone and mac, which didn't work anyway). She forwarded me on to some iPhone specialist but I think it went back to first line AppleCare and I got a woman with a thick accent I couldn't understand. She just seemed to forward me on to Bob. Bob was very helpful. He apologized that this stuff was new to everyone and they were getting slammed with support calls. We tried a few things (including resetting PRAM) but that didn't help. He did find on some forum the solution. On the iPhone I had to turn off FaceTime and Handoff and then turn them back on. That did it. Rebooting the phone didn't do it but manually turning those off and on did. It only took almost 2 hours on the phone with AppleCare (including hold time) but now a feature I'll probably never use again is working :)
Otherwise Yosemite seems nice. I'm fine with the new look though the new toolbars will take a little getting used to.
Also a new Emacs came out on Monday and seems to working well for me. Now to see if iOS 8.1 means my car can finally read text messages to me. :)

The BBC presents Your life on earth.
"Find out how, since the date of your birth, your life has progressed; including how many times your heart has beaten, and how far you have travelled through space. Investigate how the world around you has changed since you've been alive; from the amount the sea has risen, and the tectonic plates have moved, to the number of earthquakes and volcanoes that have erupted. Grasp the impact we've had on the planet in your lifetime; from how much fuel and food we've used to the species we've discovered and endangered."
In the various little boxes, the V button is a drop down to show more information. E.g., under Space Age it shows your age on all the different planets. On Jupiter I'm 4!

Badass Digest describes The Ten Scariest Film Scores Ever Composed. I can't say I've ever really considered this topic but the article has put some serious thought into it.
"Composing a scary score can sometimes be erroneously perceived as being ‘easy’ because all you need to do to elicit a response is weave ear-piercing bangs, crashes and screeches into a cacophonous mess. The skill in composing a well-crafted horror score of this nature is to impart an impression of cacophony, when in actuality, these textures are sculpted with an artistic precision that maximizes the fullest potential of fear from the narrative. It’s a delicate balance between what is visually and narratively frightening, and its aural counterparts.
Much like a good comedy, timing is everything. The setup is just as important as the payoff and every single second before or after is crucially important. Minute changes in timing have a vast effect on the overall success of the score. Anybody can create a loud bang after a prolonged period of soundlessness and elicit a jump or even a scream, but will that psychologically expose the audience enough to allow the terror to manifest itself within our own imagination? If music is not triggering our imagination, it’s not living up to its fullest potential."
Here's their list:
- The Exorcism of Emily Rose (2005)
- The Changeling (1980)
- The Omen (1976)
- Psycho (1960)
- Altered States (1980)
- Alien (1979)
- Friday the 13th (1980)
- Poltergiest (1982)
- Evil Dead (2013)
- Rosemary's Baby (1968)
1980 was a good year to be scared.
John Oliver last night was great. Here's a long segment on our failure to help those that helped us. "Translators who have aided the U.S. Military in Afghanistan and Iraq are in great danger in their home countries, but red tape is making it impossible for many of them to leave."
As a bonus, he covered the tired issue of the US Supreme Court not allowing cameras in a hilarious way.

Matthew Yglesias says It's time to push the panic button on the global economy. "One month's worth of bad data shouldn't necessarily cause a panic, but in light of all the other trends it's alarming. In particular, one would want to see that consumers who are spending less on gasoline and other energy products are pouring at least some of their savings into buying other stuff. Instead, the September report appears to show consumers pulling back across the board — even as demand from abroad is clearly falling apart. Just when it looked like hiring was poised to take off, demand for goods and services is slumping instead. A very troubling sign for an economy that, despite recent good news, is still on the weak side."
I'm not concerned about the stock market this last week, and the Yglesias article seems right to me. We still haven't addressed the real weaknesses in the economy so it's going to continue to putter along. The recent hopeful good news, well now it's pulling back, shocker.
io9 reports on A Single Breakthrough That Could Cut Costs on Solar Energy by 25% "A group of chemists at Ohio State University has invented a solar panel that stores energy without an external battery. The self-contained tuner/capacitor panels are already being licensed to industry."
"The invention also solves a longstanding problem in solar energy efficiency, by eliminating the loss of electricity that normally occurs when electrons have to travel between a solar cell and an external battery. Typically, only 80 percent of electrons emerging from a solar cell make it into a battery. With this new design, light is converted to electrons inside the battery, so nearly 100 percent of the electrons are saved."
The Intercept reports The FBI Director's Evidence Against Encryption Is Pathetic.
"FBI Director James Comey gave a speech Thursday about how cell-phone encryption could lead law enforcement to a ‘very dark place’ where it ‘misses out’ on crucial evidence to nail criminals. To make his case, he cited four real-life examples — examples that would be laughable if they weren’t so tragic. In the three cases The Intercept was able to examine, cell-phone evidence had nothing to do with the identification or capture of the culprits, and encryption would not remotely have been a factor."
"Hadn’t Comey found anything better since then? In a question-and-answer session after his speech, Comey both denied trying to use scare stories to make his point – and admitted that he had launched a nationwide search for better ones, to no avail."
"Facing the huge preponderance of evidence that encryption makes us safer, not less safe, Comey realizes he needs some solid evidence to support his side of the argument. But there’s a reason he hasn’t found it yet."
The New York Times reports Supreme Court Allows Texas to Use Voter ID Law
"The Supreme Court on Saturday allowed Texas to use its strict voter identification law in the November election. The court’s order, issued just after 5 a.m., was unsigned and contained no reasoning.
Justice Ruth Bader Ginsburg issued a six-page dissent saying the court’s action ‘risks denying the right to vote to hundreds of thousands of eligible voters.’ Justices Sonia Sotomayor and Elena Kagan joined the dissent.
The law, enacted in 2011, requires voters seeking to cast their ballots at the polls to present photo identification like a Texas driver’s or gun license, a military ID or a passport."
Here's the part that should convince you this is all to reduce voting by those more likely to vote for Democrats: "Texas has required some form of identification to vote at the polls since 2003. In the decade after, before the new law imposed even stricter requirements, some 20 million votes were cast, Solicitor General Donald B. Verrilli Jr. told the justices, while 'only two cases of in-person voter impersonation fraud were prosecuted to conviction.'"

"That’s every public street, colored by the predominant orientation of itself and its neighbors, thickened where the layout is most “grid-like” – to use an old-school woodworking metaphor, it’s as if we brushed some digital lacquer over the raw geographic transportation network data to make the grain pop.
For the detail-oriented, these are 100%-algorithmic images generated from MapZen’s Migurski-inspired October 2014 OpenStreetMap Metro Extracts as follows. First, we assign each linear street segment a compass-heading-based tone from a modified sinebow, where a 90 degree directional difference corresponds to a full color revolution, so that roads at right angles to each other have the same hue. Then, to render each point on the map, we use Proximatic, my custom high-performance k-NN engine, to calculate the length-weighted average of the colors assigned to the nearest 500 meters of street, keying render weight to the local degree of parallelism/orthogonality (derived in a similar mod-90° vector space), with rolloffs for outlying roads and territory."

Ars reports about Lockheed Martin claims “technological breakthrough” in compact fusion
"Reuters is reporting that defense contractor Lockheed Martin claims it has made a technological breakthrough that places us on the doorstep of affordable fusion energy. Supposedly, the breakthrough will result in compact fusion reactors before a decade is out.
But the Lockheed Martin press release that coincides with the coverage says little of the sort. There, the company simply states that after initial work in the area, it expects to be able to build a prototype in five years. If everything goes well, the design could 'be developed and deployed in as little as ten years.' The 'if' in the last sentence, however, is a big one."
Visualised: how Ebola compares to other infectious diseases "To give a universal metric for infectiousness, we’ve used the average ‘basic reproduction number’ (also ratio or rate). It’s a statistical measure of how likely and widespread an infectious disease outbreak might be - if nothing is done to control the situation."

NTU develops ultra-fast charging batteries that last 20 years "Scientists at Nanyang Technology University (NTU) have developed ultra-fast charging batteries that can be recharged up to 70 per cent in only two minutes. The new generation batteries also have a long lifespan of over 20 years, more than 10 times compared to existing lithium-ion batteries."
"In the new NTU-developed battery, the traditional graphite used for the anode (negative pole) in lithium-ion batteries is replaced with a new gel material made from titanium dioxide...Naturally found in spherical shape, the NTU team has found a way to transform the titanium dioxide into tiny nanotubes, which is a thousand times thinner than the diameter of a human hair. This speeds up the chemical reactions taking place in the new battery, allowing for superfast charging. "
This could be a really big deal and they say could hit the market in the next two years.

The Empire Strikes Back Uncut. "With more than 480 fan-made segments culled from over 1,500 submissions, The Empire Strikes Back Uncut (also known as ESB Uncut) features a stunning mash-up of styles and filmmaking techniques, including live action, animation, and stop-motion. The project launched in 2013, with fans claiming 15-second scenes to reimagine as they saw fit – resulting in sequences created with everything from action figures to cardboard props to stunning visual effects. Helmed by Casey Pugh, who oversaw 2010’s Emmy-winning Star Wars Uncut, the new film has a wonderful homemade charm, stands as an affectionate tribute to The Empire Strikes Back, and is a testament to the talent, imagination, and dedication of Star Wars fans.

Here's another good John Oliver story, this one on Civil Forfeiture. I don't think I've blogged about it (maybe in the twitter feed) but a friend mentioned it to me last year. The first big stories I saw about it were from August 2013. Sarah Stilman's Taken in The New Yorker (and related 20 min podcast Out Loud: Highway Robbery) and ProPublica's Law to Clean Up ‘Nuisances’ Costs Innocent People Their Homes. The ACLU has a page on Civil Asset Forfeiture.
But John Oliver is funnier:
I'm back and catching up. HBO's Last Week Tonight with John Oliver is my favorite of the comedy news shows. By being weekly he's not playing catch up with the news of the day and tends to cover a topic in some depth and often one that doesn't get a lot of coverage. Here's a perfect example.

In Focus shows the Northern Lights in the Skies Above Norway "Visible displays of the Northern Lights have been spectacular recently, for those in the far north, away from city lights. Reuters photographer Yannis Behrakis recently took a trip to northern Norway, joining others making the journey to admire and try to capture the phenomenon of the Aurora Borealis in photographs. Below is a collection of these images, looking to the skies above Troms County, Norway, last week. [18 photos]"
