Why isn’t Apple Wallet smart enough to delete old boarding passes?

by philg

Software is so smart that it will soon be driving us around, recognizing and dodging pedestrians. WIRED and similar cheerleaders for technology assure us that our software pals will also diagnose us based on medical imaging and other tests.

Apple Wallet is an app from one of the world’s leading software companies. Every time I open it there is a boarding pass from a flight that occurred a month or two ago. The software is neither smart enough to delete the pass a month after the flight (and after the location subsystem shows that the flight was actually taken) nor pop up a “would you like to delete these old boarding passes?” offer.

If this is the best that Apple can do, how is it that we can have confidence in the hard problems being solved?

Why would health care look to startups for answers?

by philg

Several executives speaking at a recent 25th anniversary celebration for a health care informatics lab spoke hopefully about solutions that might be forthcoming from startups yet to be founded. This struck me as odd. A hospital is a huge enterprise (I learned that Children’s for example, has more than $2.3 billion/year in revenue). Health care is 18 percent of U.S. GDP (compare to 4.5 percent for Singapore where people failed to realize that they needed to take opioids 24/7 and also inhale medical marijuana).

When an industry is this big, why wouldn’t it be the biggest tech companies, e.g., IBM and Amazon, that deliver solutions? The current Epic system is clunky, but why wouldn’t the Epic research lab be the place where useful innovation happens? IBM and AT&T were slow-moving, but IBM Watson and AT&T Bell Labs were the main sources of useful innovation in their day, not a handful of engineers in a garage.

What has changed that we think it will be the startups that inherit the Earth and that fix what ails us? The availability of venture capital such that nobody capable of accomplishing anything wants to work for a straight salary anymore?

Separately, a friend who is plugged into Silicon Valley told me about the latest trend. VCs will try to fund a company around a bunch of former employees of a single big company, e.g., Xooglers (former coders on the Google plantation). This protects the VC from downside risk. No matter how lame the idea is or how poor the execution, even if the startup is a complete failure it will likely still be acquired by, e.g., Google, simply because the big company wants this set of employees back and they are known quantities. The VC fund will at least get most of its money back.

Business and software blueprint for a personal portable medical record

by philg

Good news: I can share with you a complete functional and business blueprint for how to make a personal portable electronic medical record.

Bad news: The plan is from 1994 and almost no progress has been made toward any of the goals set forth 25 years ago.

A slide for the Guardian Angel system appeared during a 25th anniversary celebration for a health care informatics lab that I played a small role in starting. From the big blueprint:

Current health information systems are built for the convenience of health care providers and consequently yield fragmented patient records in which medically relevant lifelong information is sometimes incomplete, incorrect, or inaccessible. We are constructing information systems centered on the individual patient instead of the provider, in which a set of “guardian angel” (GA) software agents integrates all health-related concerns, including medically-relevant legal and financial information, about an individual (its “subject”). This personal system will help track, manage, and interpret the subject’s health history, and offer advice to both patient and provider. Minimally, the system will maintain comprehensive, cumulative, correct, and coherent medical records, accessible in a timely manner as the subject moves through life, work assignments, and health care providers.

This would be awesome to have today and yet we are as far away from it, I think, as we were in 1994. Sobering!

Why we still need Microsoft

by philg

I wanted to save a PowerPoint presentation about a recent Northwest Passage cruise to a series of HD-resolution (1920×1080) JPEGs for direct display from a USB stick to a TV.

PowerPoint will let you do this, but only at 1280×720(!) resolution.

After a brief search, I found an official Microsoft document on this subject: “How to change the export resolution of a PowerPoint slide”.

Instead of adding a dialog box to prompt the user for the desired resolution, Microsoft took the trouble to advertise a method of doing this by editing the Windows registry, complete with cautions about how “serious problems might occur” if you make any mistakes while editing said registry.

It is kind of awe-inspiring.

(How does one accomplish this goal? The advertised procedure does work and a DPI resolution of 144 results in 1920×1080 pixel JPEGs. The current version of PowerPoint included with Office 365 is 16.0. See this video tutorial if you want a little more handholding.)

Software updates before a trip now take longer than packing?

by philg

I’m heading out on a trip that will involve limited Internet connectivity. My notebook computer hadn’t been turned on for 1.5 weeks. Updating that to the latest version of Windows 10 took four tries and roughly three hours (admittedly this was a bigger update than usual and there was also a Dell BIOS update). I’m taking a Sony a7F II camera and two lenses. Software updates were available for all three of these items. Downloading them required resetting my password on the Sony web site, verifying my Sony account, download three Windows applications, running three separate Windows apps, connecting and disconnecting the camera via USB to the PC, following Sony instructions to remove the battery after each lens update, etc.

Thus, I think it is fair to say that updating devices took longer than packing up for a somewhat remote trip!

What if the Internet of Things became a reality? Given the security issues around completely automatic updates, will humans eventually be reduced to full-time sysadmins just for the stuff in their apartments?

Update: arrived in Copenhagen. Here’s the hotel coffee shop electronic menu screen:

Artificial Intelligence and commercial sex purportedly intersect

by philg

For anyone who knew Marvin, “AI pioneer accused of having sex with trafficking victim on Jeffrey Epstein’s island” is a surprise.

Apparently Jeffrey Epstein was using some of the money that he stole to run Templeton Foundation-style scientific gatherings in the Caribbean (funded with money that John Templeton earned and then skipped paying taxes on by renouncing his U.S. citizenship and relocating to the Bahamas). A woman now says that, as a 17-year-old, she was paid to have sex with the then-73-year-old Marvin Minsky at one of these gatherings. (There does not seem to be any evidence the Marvin ever left the mainland U.S. to hang out with Epstein, though. See below.)

In the 40+ years that I saw Marvin, at his office, at his home, and at conferences, he never once took notice of a young woman or commented on the appearance of a woman. He was simply not very interested in matters of the flesh.

On a more practical level, if Marvin had wanted to have sex with 17-year-olds, he could have done so legally in Massachusetts, in which the age of consent is 16. (Prostitution per se is illegal in Massachusetts, but it wouldn’t be illegal for an older person to supply a young sex partner with gifts of jewelry, housing, transportation, vacation trips, etc. (though the real money would be in a pregnancy followed by harvesting the unlimited child support cash available under Massachusetts law)) There were also quite a few graduate students who had sexual relationships with successful academics and, lo and behold, found that the path to a tenure-track professorship was wide open. There was never any hint or rumor around Marvin of a sex-for-career-advancement exchange (or any other kind of affair).

Ever since Stormy Daniels dominated the mainstream media, I guess it isn’t surprising that people whose job is having sex in exchange for money are newsworthy. But if they’re claiming that they were paid to have sex with those who are deceased, and there is no evidence to support these claims, should reporters be broadcasting these tales? This is the first one about someone that I know personally and it rings false.

USB-C more durable than USB-A?

by philg

When trying to charge a phone from public charging stations and power outlets on airliners, one thing that I’ve noticed is that the USB-A (traditional rectangular) ports tend to be “loose like wizard sleeve”. Unless one is willing to hold the connector and apply pressure, therefore, they are useless for charging. I’m not sure how they get like this. I can’t remember a USB-A connector failing mechanically on a home computer or charger. Is it just that if 1,000 different cables have been plugged over a one- or two-year period that the socket is stretched out to the size of the largest? Compare to at home where I might use only three or four different cables in any given socket.

What’s the prognosis for USB-C? Are the tolerances more precise such that the public connectors will remain functional?

Has disk drive progress stalled?

by philg

Magnetic disk drives were supposed to get more capacious, on a per-platter basis, at a steady “Kryder rate” (40 percent per year).

Now that it is time to get a monster hard disk drive to run Windows File History and try to recover from the CrashPlan debacle, I’m trying to figure out what progress has been made since April 2015 when I purchased a 6 TB hard drive for $270. If capacity had grown at 40 percent per year, with the same number of platters and roughly the same cost, this should be a 16 TB drive for $270. One can purchase a 16 TB drive from Amazon, but it costs $580 and some of the extra capacity comes from extra platters (9 versus 5 for the WD60EFRX that I bought in 2015).

If you want to spend $270 on a 5400 RPM drive, you get 10 TB, not a huge increment over 6 TB after more than four years.

Have all of the brightest minds in storage moved to work on SSD?

What’s a good online backup service? (Crashplan can do only 10 GB per day)

by philg

I used to back up my computer with Crashplan, but the service failed after I parked some big videos from our MIT Ground School class on a secondary drive. I was able to get it started again by beefing up its RAM allocation to 8 GB (it seems to use 3-5 GB; this is why I want every computer to have 64 GB of RAM minimum!) and cutting the backup interval to once/day (attempt to prevent a new backup starting from causing an in-progress upload to file).

The backup is unbelievably slow. Windows says Crashplan uses 0.1 Mbps most of the time, i.e., about 1/10,000th of the provisioned Verizon FiOS 1 Gbps symmetric link. My information will be at risk of drive failure for the next 83 days (about 830 GB of stuff that Crashplan missed during its failed period).

I pinged the Crashplan folks for support. It turns out that their goal is 10 GB per day:

Looking at your recent history, I’m seeing that you’re getting above-average upload speeds to us. CrashPlan users can expect to back up about 10 GB of information per day on average if their computer is powered on and not in standby mode.

In other words, the consumer who buys a $360 laptop at Amazon with a 1 TB hard drive, fills it up with family photos and videos, and then subscribes to the service will not have a complete backup until 3.5 months of being continuously connected (maybe not for a year if the laptop is turned on only when in use). The consumer who captures or modifies 1 hour of video every day will never get a complete backup, I don’t think.

[Update 5/6: Since the bandwidth used, according to Windows, is the same 24/7, I’m 99 percent sure that Crashplan is throttling to 100 kbps. The customer support emails use some careful language: “We do not apply throttling based on the size of your backup. We also do not limit upload speed based [on?] file sizes or types.”]

I started with Crashplan in 2012, according to this post on the topic:

[Update 11/15/2012: Based on the comments below, I installed CrashPlan. It is uploading 2.2 Mbps currently, maxing out the admittedly feeble Comcast cable modem upload capacity. So this makes it 22 times faster than Carbonite, throttled to 100 kbps.]

Given that it is only 1/20th of its former speed, I wonder if Crashplan has now discovered the miracle of throttling while charging customers for “unlimited” service.

“Why I Switched to Backblaze from CrashPlan” (February 2017):

I failed to get CrashPlan to complete a single successful backup on my new machine for a full month. … After I cranked up Backblaze to the fastest possible, I was shown a transfer speed of 208.14Mbps. Remember CrashPlan? That was at 2.4mbps. So 100x the speed. But could Backblaze really do this in an actual upload? … .it only took Backblaze 18 hours to upload 641GB of data. 735 thousand files. … I’m switching over to Backblaze because of the nice interface, and because of the speed, and well, mostly because they actually can back up my computer.

How about following this guy with a switch to Backblaze? It is $60/year., half the price of Crashplan at $120/year for a single computer, but I think Backblaze adds fees for persistent storage of older versions (6 cents per GB per year, so a 6 TB hard drive could run up a $360/year bill?). This memory usage comparison showed that Backblaze required only 1/25th as much RAM as Crashplan.

Or maybe it makes sense to subscribe to both? Use Backblaze to make sure that you actually can restore your computer if it fails within one of the multi-month windows in which Crashplan is hundreds of GB behind. Use Crashplan to restore an ancient version of a file.
