Samsung Galaxy S7 Active announced with bigger battery

I finally couldn’t live with my Samsung Galaxy S7 due to the limited battery life, though I think that was mostly due to a combination of (a) apps I had loaded, and (b) Android’s willingness to let any app do whatever it wants, including run the battery down. Among other things I wanted a bigger battery and inherent toddler-proofing.

Samsung has released the S7 Active, which has… 33 percent more battery capacity and a toddler-proof package: dpreview. Only on the AT&T network, unfortunately.

[Separately, given the mindset of many app programmers (“My App is the Most Important”), I don’t see how Android can ever compete against iPhone without somehow putting every app on a power budget. It seems to be the case that iOS will protect the owner against an app that wants to run every 15 seconds in the background but Android will not. Apple at least bothered to ask the question “How should a battery-powered device’s operating system be different from that on a device that plugs into the wall?” Here’s some email from a friend who loves his Samsung S7 and is willing to put some effort into it:

Regarding your S7 battery-drain post from last month: I just discovered that the mediocre battery life on my Note 5 was because the phone wasn’t going into deep sleep mode when idle. Using the CPU Spy app, I discovered that the phone wouldn’t sleep with Bluetooth enabled, and tracked the problem down to my Pebble or Health apps (or some interaction between them).

After reinstalling everything, I have deep sleep working properly and it makes a huge difference–essentially zero battery drain when the phone is idle (despite having WiFi, BT, GPS, etc turned on, my Pebble watch connected, and various social-media apps standing by for messages).

… [one day later]

Speaking of debugging effort, it turns out I’d mis-identified the source of the BT wakelock. It wasn’t the Pebble or fitness apps; after some web-searching, I found out it’s the CVS app.

CVS recently installed BT beacons in their stores to bombard your phone with ads about products you’re standing near. Apparently they decided it’s a good idea to keep your phone from ever sleeping, lest you miss a nearby ad. No matter if you’re not even in CVS, or not even using the app–it autostarts, and runs all the time.

It turns out you can solve the problem by disabling in-store notifications in the app’s settings–provided you can figure out to do so. Almost everyone, of course, will have no clue it’s CVS that’s cutting their battery life in half. They’ll just think their phone sucks.

How many consumers will have the computer knowledge and diligence that this guy had? And why should a phone owner have to do the kind of performance engineering formerly the exclusive domain of Unix server sysadmins?

Here was my advice to a non-tech friend who couldn’t resist getting an S7: “I would install just one application at a time. Maybe one every 3 days. If the battery life falls apart, throw that app out or configure it so that it can’t run in the background.”]

Readers: What do we think? Can Tim Cook take a sufficiently long break from his Social Justice War to supervise the development of an iPhone 7 that is a better practical photography tool than this new indestructible Samsung?

What could be more useless than a Microsoft store?

When the first Microsoft stores came along I asked myself “What could be more useless?” Consumers know what Windows is like. Microsoft doesn’t sell a lot of hardware and most of it is stuff such as keyboards that you would throw out in the event of a failure.

Yet the Microsoft store in the Burlington Mall here in the Boston area proved to be useful for trying out a lot of different laptop keyboards. They have a range of laptops from ASUS, Acer, Dell, HP, et al. It turned out that there are some subtle differences among them. For my hands the worst machine by far was the HP Spectre x360. The trackpad is super wide and thus every time I tried to type my palms would brush the track pad and cause mayhem. Spacing was remarkably consistent across laptops though I had imagined the Dell XPS 13 to have a cramped keyboard. I ended up liking the Dell XPS 15 and the Surface Book the best. I opted for the Surface Book due to (1) a pimped out XPS 15 configuration (e.g., with 1 TB SSD) was over $2,500, (2) I want to experiment with traveling using the Surface Book as both tablet and laptop (i.e., leave the iPad at home), (3) the Surface Book is somewhat lighter and more compact. I will miss the Dell’s 4K-resolution big screen.

I wasn’t sure how much I would love the Surface Book so I opted for the lower-end 8 GB RAM/256 GB SSD version. I will have to be judicious about which Dropbox folders to sync. It is possible add a monster SD card for additional storage at a reasonable price, though of course then it has to be removed when it is time to plug in a camera SD card.

Full report on the Surface Book to follow.

Separately, it is always interesting when the Obamacorps (American workers who came of age during the past eight years) try to deal with something technological. One of the senior saleswomen there assured me that adding a GPU to the inside of a Surface Book would “make the colors more vibrant.” (The online tech specs suggest that it is the same physical screen on all models.)

Overall I would say that the atmosphere in the Microsoft store is a lot better than in the Apple store, where it looks like an African rift lake ferry full of restive passengers with cracked screens has just unloaded.

Preferences in government contracting for immigrants?

At a recent social gathering an attorney told me about her job at a company run by an immigrant from China. She said that due to his immigrant status the firm goes to the head of the line (along with women-owned and minority-owned companies) whenever there is a government contract. She seemed like a reliable source but at least with a Google search I can’t find the regulation or law that would give an immigrant priority over a native-born American in soaking up the tax dollars (e.g., $182 million to build and run a campground reservation site).

Readers: Is anyone familiar with these rules?

Facebook postings from someone who doesn’t need to get a job

The First Amendment doesn’t apply to anyone who needs to hold onto or get a W-2 job. Expressing a politically unpopular or unacceptable idea puts an employee on a greased slide to the front door.

Here’s a recent Facebook posting from a friend who runs his own business:

Sent my 6-year-old daughter to buy something Target so that she could learn to be independent. I waited about 30 feet away as she checked out some Pokemon cards on her own using my credit card.

From this ensued a discussion among his friends regarding the pros and cons of free range children. Example:

Given that folks have been charged for letting their 9 year olds play in the street with out the parents being there, I would be cautious. Also, use cash. You are technically the only one that can use that card.

The self-employed original poster then noted

I am 100% sure my kids would not run into a wild animal exhibit and jump down a 15 foot concrete wall to enter a moat.

(Reference to an incident that led to the shooting death of Harambe, an endangered gorilla at the Cincinnati Zoo.)

Wall Street Journal hires crackhead to analyze the economics of universal basic income?

Charles Murray, (in)famous for authoring the Bell Curve, in which he pointed out that the world circa 1994 was unfriendly to those with a low IQ, has an editorial in this weekend’s Wall Street Journal: “A Guaranteed Income for Every American: Replacing the welfare state with an annual grant is the best way to cope with a radically changing U.S. jobs market—and to revitalize America’s civic culture.”

Here’s his proposal:

In my version, every American citizen age 21 and older would get a $13,000 annual grant deposited electronically into a bank account in monthly installments. Three thousand dollars must be used for health insurance (a complicated provision I won’t try to explain here), leaving every adult with $10,000 in disposable annual income for the rest of their lives. …

The UBI is to be financed by getting rid of Social Security, Medicare, Medicaid, food stamps, Supplemental Security Income, housing subsidies, welfare for single women and every other kind of welfare and social-services program, as well as agricultural subsidies and corporate welfare. As of 2014, the annual cost of a UBI would have been about $200 billion cheaper than the current system. By 2020, it would be nearly a trillion dollars cheaper.

How could this work in a country with the world’s most expensive health care system? Murray says people will spend $3,000/year on health insurance. But Medicare costs more than $10,000/year per beneficiary (2009 data). Medicaid also costs more than $3,000 per year (2011 data). Consider two non-working parents with five kids. Right now they will get an array of taxpayer-funded services whose value could exceed $100,000 (housing, Medicaid, food stamps, Obamaphones, etc.). How could they survive on $26,000 per year when that wouldn’t even pay for a medical/dental policy in the private market?

Separately, Murray’s article demonstrates the depth of American political support for a government-run system that turns heterosexual sex into cash:

The unemployed guy living with his girlfriend will be told that he has to start paying part of the rent or move out, changing the dynamics of their relationship for the better. … Or consider the unemployed young man who fathers a child. Today, society is unable to make him shoulder responsibility. Under a UBI, a judge could order part of his monthly grant to be extracted for child support before he ever sees it. The lesson wouldn’t be lost on his male friends.

If Murray advocates for free enterprise, why doesn’t he support the decision of an adult “girlfriend” to pay most of the household expenses for an unemployed man? Can we not infer that he is providing her with something that she values as much or more than the space and food he consumes? Would Murray consider an unemployed woman living off the fruits of a man’s labor to be equally reprehensible?

In a country that offers on-demand abortion and for-profit abortion, Murray scolds the second example unemployed man for the birth of a child. Why isn’t his sex partner scolded for not educating herself regarding U.S. family law (see California, Florida, and Massachusetts, for example) and having children who are cashflow-positive?

The author is against more government spending but he wants to continue to assign a taxpayer-funded judge and prosecutor to determine the profitability of every out-of-wedlock birth in the U.S.?

Readers: Can this WSJ piece be read as anything other than a fantasy? Could it possibly work without cutting U.S. health care costs by more than 50 percent? And if we could do that, with almost 10 percent of additional GDP available every year to invest or spend, wouldn’t our economy then be in such great shape that we wouldn’t need to tweak our welfare system?

Could the idea be rescued with some tweaks? How about tackling the elephant in the room head-on: universal health care at a modest budgeted cost. If the U.S. had an English-style system that covers everyone to at least a basic level of care, then older Americans could live off their UBI instead of handing it over to the health care industry. Today’s Welfare parents with five kids wouldn’t be doing so great at $26,000 per year, but at least they wouldn’t spend 100 percent of that money on health care. Speaking of kids, if nobody gets a UBI until reaching age 21 it will be tough on current Welfare recipients who have produced children with the expectation that taxpayers will provide adequate housing, food, etc. On the other hand, if ownership of a children produces a $13,000-per-year revenue stream to an adult that will presumably encourage adults to have more children and fight over ownership (“custody”) just as they currently do in U.S. family court. The difference in spending for a married couple with and without a child is about $4,300 (see discussion of UCLA Professor William Comanor’s analysis in the Methodology chapter). This is in the neighborhood of maximum child support awards that are obtainable, even after having sex with a truly rich person, in many European jurisdictions. What if health care were covered and each child yielded a $3,000-per-year revenue stream for the adult owner(s)? Now the married couple with five kids gets $41,000 per year. That would put them above the poverty line for a family of 7 (source) and, of course, they could supplement that income with paid work if they wished to. Because the children wouldn’t be hugely profitable there wouldn’t be an economic incentive to have more kids (though of course people who enjoy having children around might have more kids even if profit-neutral).

I think that it would be more interesting to see an analysis of the economics of a system in which major health care costs did not come out of the UBI and in which the additional expenses of children were accounted for at least partially. The current litigation-based system of establishing private-sector adult dependency (alimony), child ownership (custody), and child profitability (child support), probably costs the economy at least $150 billion per year ($50 billion in direct expenses and at least another $100 billion in lost productivity either from people following incentives not to work or from preparing for the courtroom rather than working). If that were torn down because an alimony or child support plaintiff can now collect UBI, that would enable UBI to be bumped up by roughly $500 per American per year. Health care remains the tough one, though. We have a track record since the 1960s of crazy high costs and high growth rates in those costs, fueled by tax breaks for insurance and government spending through Medicare and Medicaid. Is it reasonable to assume that we could one day cut health care spending to only double Singapore’s, as a percentage of GDP?

How can the authenticity of an iMessage be established? (Amber Heard v. Johnny Depp)

One issue in Amber Heard’s lawsuit against Johnny Depp is the authenticity of some iMessages. The Daily Mail has a story laying out both sides: “Johnny Depp’s assistant claims his text messages apologizing to Amber Heard for the actor’s actions are FAKE and have been heavily doctored.”

iPhones have all kinds of crypto. Is there a cryptographic hash on a screen shot such that if Amber Heard were to produce the original files we would be able to tell that it was an authentic screen shot from a particular date from either a particular iPhone or at least some iPhone?

What about up in the Apple server farm? iMessages are encrypted but can Apple read them all? Does Apple save them all?

If these (very convenient for a divorce plaintiff) messages are not authentic, how would Amber Heard and her legal team have gone about fabricating the depicted images? Straight up artistic work in Photoshop? Or better to engage in an exchange with a trusted associate and then use Photoshop to cut out and substitute the central portion of the screen?

Update: A friend pointed out that there are multiple web sites, e.g., www.ios7text.com, that will generate screen shots like the ones that Amber Heard may be presenting as evidence. Here’s an example that I created:

20160604-hillary-clinton-imessage-exchange

 

In fact, I wonder if this is the service that was used to create the ones offered by Amber Heard and her attorneys. My actual iPhone shows “Details” in the upper right, but ios7text.com defaults to “Contact” in the upper right, as do the screen shots displayed by the Daily Mail. My iPhone shows a microphone icon at bottom right, but ios7text.com and the displayed images show the word “Send” at the bottom right.

Minecraft Company History and Swedish Gaming Industry

I listened to Minecraft: The Unlikely Tale of Markus “Notch” Persson and the Game that Changed Everything as an audiobook (could be cut in half). I hadn’t realized that the Swedish computer game industry was so huge. The authors say that about 22 percent of computer game revenue in Europe goes to Swedish companies, mostly located in one neighborhood in Stockholm, despite the country having less than 2 percent of Europe’s population.

What do folks think accounts for this? The long winters? It doesn’t seem to be favorable tax treatment. A Swedish gaming success would be taxed at the capital gains rate of 30 percent, higher than some other European countries and the U.S. (an American would pay 20 percent federal tax, another 4 percent Obamacare tax, and then another 13 percent in California, but the average combined rate across all states is 28.6 percent).
