trendia··on Google Pay
The most Google thing to do would now be to deprecate Android pay, no longer support merchants who don't upgrade their point of sale systems, and provide no contact line for support.
trendia··on We Know Almost Nothing About This Secret US Government Airline
I use uMatrix. Sometimes I get an error like "Your adblocker has caused this site to crash. Disable your adblocker".

When this happens, I just disable all javascript on the page, and the page loads fine -- no error, no alert, just the content. In fact, the page loads faster, since 95% of Javascript is not used to improve the usability of the site.

Come on, Mailgun.

Let's Encrypt is free and takes less than 5 minutes to set up (using certbot).

Does this vulnerability affect Linux only, or any operating system?
trendia··on How to hack a turned-off computer, or running unsigned code in Intel ME [pdf]
There were investigating flashing the ME for their compute cloud processors [0] to avoid the possibility of an ME vulnerability being exploited, which would greatly harm their reputation.

trendia··on The One Product You Should Buy Online: Eyeglasses
Part of the reason eyeglasses are so expensive is "vision insurance", which is not insurance at all. By definition, insurance is the spread of risk of a high-cost, low-probability event over a large population so that no individual has to pay a huge sum if the event occurs. For instance, eye insurance would have a small premium that would pay out if an eye injury occured that required very expensive medical care. However, modern "vision insurance"

1. won't pay if you injure your eye

2. doesn't spread any risk over a population

Instead of reducing risk, vision insurance simply spreads a known cost over a period of time. If each customer would pay $240 / yr on eyeglasses, it allows them to instead pay $20 / mo. That is not insurance -- that's a payment plan!

So, why does it exist and why does it increase price? Very simply, vision insurance can be provided by a company to its employees and deducted as an expense. This allows the employee to avoid paying personal income tax on wages, which would happen if the $240 were provided directly to the worker. Thus, it is cheaper for the company to provide vision insurance than to increase wages to provide $240 in after-tax take home pay.

Because the money tied up with vision insurance can not be used for anything other than glasses (e.g. you can't cash out a vision plan and spend the money on video games or travel), there is no incentive for the end customer to spend less on glasses. They will want to spend as much as possible while still remaining below the maximum budget from the plan. As a result, this distorts the normal financial incentives in a marketplace.

As a result of the favorable tax position and lack of cost incentives, vision insurance inflates the price of eyeglasses and exploits a de facto subsidy from the taxpayer to the eyeglass company. This increases the profits of the eyeglass company (owned by Luxottica) at the expense of the consumer (and to the detriment of anyone who buys their glasses out of their own pocket)

IIRC, Google has been flashing the code portion of the ME (rendering it useless)
trendia··on Gittup, a Linux distro on top of Git
Does GitHub have to pay a fee to use Git in their name?
trendia··on Ask HN: Any recommended books on developing mental models?
How do you distinguish between deconstruction that is accurate vs one that is "useful" but inaccurate?

It seems rather easy to use deconstruction to see things that aren't really there.

Anyone know why this was flagged?
trendia··on Ubuntu Phones Will Soon Run Android Apps
Hopefully this will spur ports for more phones. Currently the only two major devices are the Fairphone 2, which is struggling to meet demand, and Nexus 5, which came out in 2013.
trendia··on Apple’s New iPhones Get a Lukewarm Reception from Buyers
They don't even need to follow a normal distribution; the central limit theorem will apply to most naturally-occurring distributions.
trendia··on Chrome is Not the Standard
Lest we forget:

A third party company (funded by venture capital) created something called "Pocket", which allowed you to save any article you were reading to their service. Pocket had an extension that you could choose to download & enable on your Firefox browser.

For apparently no reason at all, in June 2015, Mozilla integrated the proprietary Pocket into their open source browser, not just as an optional extension but as part of the default installation. The only way to disable Pocket was to go into "about:config", as the option was not available in the "Extensions" toolbar. (Later, Mozilla Corporation purchased the company Pocket, though at the time Pocket was introduced as an inextricable part of Firefox, Pocket was a separate company.)

The Mr. Robot addon had some similarities with the Pocket fiasco:

1. it was pushed to users without their knowledge or consent

2. it was integration of a plugin for a private company into an open-source project

3. it was a decision by marketing, and not development

I am not quite sure how or when we can begin to trust Mozilla Firefox, and what they would need to do to regain that trust.

trendia··on Carrie Fisher’s Private Philosophy Coach
Your article about philosophy enrollment is from 2008. The trend has reversed, though both the increase and decrease in humanities majors were relatively minor (12.5% vs 15%)

trendia··on The Google-Facebook Duopoly Threatens Diversity of Thought
The Justice Dept has a very strict definition of monopoly [0] -- it requires both 1) the ability to raise prices profitably above that in a competitive market, and 2) anticompetitive conduct.

That means that Google receiving 90% of all searches wouldn't automatically imply market power or anti-competitive conduct, and I can't see how Google or Facebook can raise their prices higher than a "competitive market" if they don't charge anything for their product.

How would a competitive market in search and social networking even look?

trendia··on A friend of mine died and I didn't know because of algorithms
Even when I enable "Most Recent", it doesn't show every post from all of my friends. There are posts that show up on "Top Stories" that don't show up on "Most Recent."

How does that make sense?

trendia··on Older Adults' Forgetfulness Tied to Faulty Brain Rhythms in Sleep
From the paper, it looks like the area involved is the medial pre-frontal cortex (mPFC). Give mPFC's role in memory, my initial suspicion is that the brain rhythms are a symptom, and not a cause, of memory loss. That means that fixing the brain rhythms might not fix the underlying memory problems.

It's also worthy to note that moderate exercise can improve connectivity of the mPFC, so that is at least one way to avoid these troubles.

trendia··on Ten years of professional blogging – what I’ve learned
In the publishing business, titles are usually chosen by the editor, not the author.

Although the editor has a tough job, I don't think anyone would say that they're doing more work than the person who wrote the piece.

trendia··on ITX-sized 7-node ARM-64 cluster
Not to diminish this feat, but I wonder how the Phoronix benchmarks compare between an ARM cluster and a single x86 chip. Consider the OpenSSL benchmark.

A Sopine A64 compute module costs $29 and performs 15.05 OpenSSL signs / second [0].

An AMD Ryzen 1700 costs ~$300 and performs 986.73 OpenSSL signs / second [1].

So, if you spent $300 on 10 Pine64's, you would achieve approximately 150 signs / second, but for the same cost you could just buy the AMD chip and achieve approximately 6.5x better performance for the dollar.

trendia··on How our housing choices make adult friendships more difficult
Not OP, but:

"But when we marry and start a family, we are pushed, by custom, policy, and expectation, to move into our own houses. And when we have kids, we find ourselves tied to those houses."

trendia··on How brands secretly buy their way into Forbes, Fast Company, and HuffPost stories
I suspect that readers of fashion magazines are OK with that for the same reason that people used to read the Sears catalog: you know they're selling you something, but it's stuff you want to buy.
trendia··on In a Venezuela Ravaged by Inflation, ‘a Race for Survival’
Cuba has had terrible shortages and starvation, including one especially bad situation in the 90's.

> I would leave my house at 8:30 in the morning with a pathetic excuse for a breakfast in my stomach: a bread roll and a glass of sugared water (milk was a luxury at the time, and all food was expensive). The dollar, which was illegal at the time, came to be valued at 120 Cuban pesos. Anyone caught carrying that currency risked a long time behind bars.

There is a hard limit of ketogenesis: about 185g of ketone bodies per day [0].

(That's about 2 lbs every 3 days).

trendia··on How does one get the system to actually use the IPv6 Temporary Addresses?
"Initially browsers use the temporary IPV6 address. After a while they start consistently using the permanent one."

This is the most troubling aspect to me. The process of enabling the random ipv6 address would be:

1.Click the "enable" checkbox

2. Check if it's working. (initially, it does)

3. Forget about it for the next 12 months

Somewhere between Step 2 and Step 3, the feature spontaneously turns off and the ipv6 address is leaked, and the user is none the wiser.
