xlm1717··on The Case Against Reality
It's an article edited for lay audiences. It is for people who don't have the expertise to evaluate his proofs.

You can look up his research, though, if you want. If you have an expert friend you can have that friend explain it to you.

You can find a list of his publications here: http://cogsci.uci.edu/~ddhoff/publications/

This is one of his papers that quantifies the ideas he talks about in the article: http://cogsci.uci.edu/~ddhoff/HoffmanSinghMarr.pdf

In the paper, he does define what he means by "see reality as it is".

xlm1717··on Real story of “Yelp Girl” who called out CEO for low pay
That's not the market demanding it. Yelp could easily fire uppity workers and replace them with people willing to work for that wage.
xlm1717··on Real story of “Yelp Girl” who called out CEO for low pay
I think that's what Yelp ended up doing with Eat24, moving the office to Phoenix if I recall correctly.
xlm1717··on The real reasons you procrastinate – and how to stop
>Instead of focusing on feelings, we have to think about what the next action is, Pychyl says. He counsels people to break down their tasks into very small steps that can actually be accomplished. So if it’s something like writing a letter of reference, the first step is just opening the letterhead and writing the date.
xlm1717··on Why Garbagemen Should Earn More Than Bankers
Talk about rose tinted glasses! You would need to invent some new product that did those things for kids and convince parents to buy it, otherwise no one will ever pay you millions to make kids happy and teach them something.
xlm1717··on Syndicate Wars Port
That is what frustrated me about it at first. Once I got through those tedious first few levels though, and you unlock some of the more fun power-ups, the game gets enjoyable.
xlm1717··on College Sex-Assault Trials Belong in Court, Not Campus (2014)
Who has time for due process when such misogynistic injustice is taking place.
xlm1717··on How Americans Became So Sensitive to Harm
Excellent piece here. Does a great job of demonstrating "concept creep" from both liberal and conservative ideologies, and of describing how we got to this situation in the first place. The bullet points towards the end summarize the article perfectly:

>“by applying concepts of abuse, bullying, and trauma to less severe and clearly defined actions and events, and by increasingly including subjective elements into them, concept creep may release a flood of unjustified accusations and litigation, as well as excessive and disproportionate enforcement regimes.”

>“...concept creep can produce a kind of semantic dilution. If a concept expands to encompass less extreme phenomena... then its prototypical meaning is likely to shift... If trauma, for example, ceases to refer exclusively to terrifying events that are outside normal human experience, and is applied to less severe and more prevalent stresses, it will come to be seen in a more benign light.”

>“...by increasing the range of people who are defined as moral patients—people worthy of moral concern, based on their perceived capacity to suffer and be harmed—it risks reducing the range of people who see themselves as capable of moral agency.” There is a tendency “for more and more people to see themselves as victims who are defined by their suffering, vulnerability, and innocence...The flip-side of this expanding sense of victimhood would be a typecast assortment of moral villains: abusers, bullies, bigots, and traumatizers.”

>Expanding mental disorder “can pathologize normal experiences, generate over-diagnosis and over-treatment, and engender a sense of diminished agency.”

Of all these, I find the tendency towards victimhood particularly troubling. We're seeing a generation of kids growing up blaming everyone but themselves for their problems, and demanding that someone else change to solve their problems instead of learning the resiliency needed to survive and thrive. Couple that with the tribalism of said victims setting one group against the other, and we're setting ourselves up for civil unrest in the near future.

xlm1717··on Curious Link Between the Fly-By Anomaly and the “Impossible” EmDrive Thruster
It only looks like conservation of momentum is violated. From the article:

>The cone allows Unruh radiation of a certain size at the large end but only a smaller wavelength at the other end. So the inertia of photons inside the cavity must change as they bounce back and forth. And to conserve momentum, this must generate a thrust.

The new idea introduced is the quantization of inertia at small accelerations. As far as I understand it, from one end of the cone to the other there isn't a smooth change of inertia. This depends on the idea of Unruh radiation, and the reason the article gives for quantization of inertia is that as accelerations get very small, Unruh radiation wavelength becomes larger than the observable universe, forcing unruh radiation to take whole-value wavelengths (quantization). Again as far as I understand it, the inertia of photons on one end of the cone takes a different quantized value of inertia than the photons on the other end. So the thrust isn't a violation of conservation of momentum. The thrust is necessary to not violate conservation of momentum.

>Seems stupid the (possibly) most groundbreaking advance in propulsion ever made, can't get a million or two when we collectively gamble more than that each day at casinos lotteries and horses races.

Perhaps they need to set up a crowdfunding campaign to get those people betting on their experiment, gambling on a science experiment rather than a game of chance.

xlm1717··on Misruption: “Software is eating the moral compass”
City and state borders are very different to national borders.
xlm1717··on Misruption: “Software is eating the moral compass”
We have enough citizens. It's not that companies need workers, it's that they need cheap workers.
xlm1717··on Could 'actual innocence' save the broken US justice system?
Not just the justice system, but society in general. If you're arbitrarily targeted by the internet outrage mob for doing or saying something they don't like, your life can be ruined without a fair due process, and the internet does not forgive even if you're innocent.
xlm1717··on Why you shouldn’t use jQuery but plain JavaScript
Speaking to the reason he's writing this, if a vacancy is asking for jQuery, it probably means they're using jQuery (obvious). The author mentioned other stuff you can use to get specific jQuery functionality, but I think it should be emphasized that if you just got a job where jQuery was a requirement, you should look into implementing alternatives ASAP. One good recommendation I have is to use MinifiedJS:

http://minifiedjs.com/

It has a lot of the things you would need jQuery to do and is tiny and cross-browser. If pure JS isn't an option, MinifiedJS is the next best thing. For now, most web developers should still learn jQuery, but they should transition stuff off jQuery so one day it's not as widespread a requirement.

xlm1717··on Physicists Hunt for the Big Bang’s Triangles
Everyone does this when they try to write physics for the general public. Very few people in physics or physics writing know how to make good analogies.

As far as the structure goes, they're talking about structures approaching literal geometric shapes visible in the large scale structure of the universe. Basically, if Lucy was in the sky, they would find diamond-shaped structures, in addition to triangles, pentagons, etc. (My poor attempt at analogy!)

xlm1717··on New research shows brain is directly connected to the immune system
The worst part is it looks like they wanted the text to have a nice gray shade of #666, which is OK to read on a white background, but for some reason decided that white on black is better.
xlm1717··on Man accidentally 'deletes his entire company' with one line of bad code
One take-away from this is that it's probably better to save your backups somewhere where you can't delete them. Make sure that nothing using rm touches your database backups. Also, try to keep them backed up in multiple places. For example, store backups on a server you own, and on a cloud server, like on S3.
xlm1717··on Russian photographer matches random people with social network photos
This describes almost exactly the world of the video game Watch Dogs. Didn't necessarily use a photo though, just a connection to the other person's phone.

In the world of the video game, people did adapt to it. However, there was a faction that actively tried to destroy that system.

xlm1717··on What is BuzzFeed, really?
Not even that profitable, as another commenter linked to:

xlm1717··on The Curious Case of JavaScript’s `sort`
It might have made more sense to not have default behavior and force the user to specify how they want to sort. They could also have done what PHP did and provided several different .sort functions depending on how you want to sort.
xlm1717··on The Curious Case of JavaScript’s `sort`
It can easily be fixed by passing a sorting function...
xlm1717··on The Curious Case of JavaScript’s `sort`
Where is the issue comparing 1 and 11? 1 < 11 still returns true. [11,1].sort((a,b) => a -b) still returns [1, 11].
xlm1717··on The Curious Case of JavaScript’s `sort`
It's not that it sometimes infers what you want to do. It's that it has defaults and if you want to do something besides the default, you need to specify what it is you want to do.
xlm1717··on The Curious Case of JavaScript’s `sort`
Exactly. If even W3Schools describes the default behavior, it's not exactly a secret.
xlm1717··on My Disastrous Experience with Ubuntu 14.04 LTS Trusty Thar (2015)
Like the author, I also tried to upgrade from 12.04 to 14.04. The difference is I was on a desktop VM. I went with just upgrading the existing VM thinking it would take less work than spinning up a new VM and transferring all my files and settings, but that turned out to be a huge miscalculation.

Originally left it to upgrade overnight, only to come in the morning (this is on my work machine) to see that it hanged somewhere in the process and wouldn't move on without user input. So I proceeded with clicking through all the prompts, and when 14.04 first loads, it's SO SLOW. Long story short, it took me 4-6 hours to finally get it usable. The whole time I was thinking, "how could they mess this up so badly?"

The host OS for the VM is Windows 7, and I have to agree with the author, it is much better to use. I only run the VM for the command line, but may upgrade to Windows 10 when Ubuntu on Linux comes out of beta this summer.

xlm1717··on A week in Cuba was the most educational trip of my life
>I was struck over and over how thrilled the people were to know we were American and the sheer excitement that more of us are coming.

It's all about the money. American dollars can buy luxuries the Cuban peso can't afford, and that's something anyone can get excited about.

xlm1717··on The sugar conspiracy: sugar—not fat—is the greatest danger to our health
I found (2) really fascinating. I read a story recently about a study where they paired two people, gave them the exact same diet for a few weeks, and used continuous glucose monitoring to determine their glucose curves. It was striking that different people could have extremely different reactions to eating the exact same thing.

They speculate that it may be due to differences in gut bacteria, but still aren't sure why people react differently to the same food.

xlm1717··on Panama Papers Reveal Clinton’s Kremlin Connection
They don't just have ties, John Podesta is Clinton's campaign chairman. And the Podestas aren't just lobbying for Russia's biggest bank. As the article states, the majority shareholder in Sberbank is the Russian Central Bank. From the Wikipedia page on Sberbank of Russia (https://en.wikipedia.org/wiki/Sberbank_of_Russia#Ownership):

"The majority shareholder of Sberbank is the Central Bank of the Russian Federation, owning 50%+1 voting share of Sberbank's voting shares."

Effectively, the Russian Central Bank controls Sberbank, but ostensibly Sberbank is a private institution. The Podesta Group registered as a lobbyist for Sberbank, which effectively gives the Russian Central Bank a lobbyist in Washington. If the Russian Central Bank had registered directly with the Podesta Group, as the article states the Podesta Group would have to register as agents of the Russian government under the Foreign Agents Registration Act.

The wikipedia page on the Foreign Agents Registration Act (https://en.wikipedia.org/wiki/Foreign_Agents_Registration_Ac...) states:

"...[requires] that agents representing the interests of foreign powers in a "political or quasi-political capacity" disclose their relationship with the foreign government and information about related activities and finances. The purpose is to facilitate "evaluation by the government and the American people of the statements and activities of such persons.""

Arguably, the Podesta Group is not facilitating evaluation of statements its making on behalf of Sberbank, and by extension the Russian Central Bank, because it registered as a lobbyist for a bank controlled by a state-owned bank. The Russians suffered heavy sanctions recently. It doesn't stretch the imagination that the Podesta Group received money from Russia to lobby Washington to drop those sanctions.

As the article states towards the end, if Clinton wins the election, John Podesta stands to gain a position of power in a Clinton administration. If John Podesta benefited from money provided by a foreign government (again, Sberbank is controlled by the Russian Central Bank), then that's a relationship the Clinton campaign needs to explain.

xlm1717··on Why Go gets criticized so much
>Obviously, not everyone hates Go.

Well, at least the author saves me the time reading the rest of the article.

xlm1717··on Venezuela Declares Every Friday a Holiday to Save Electricity
It would seem to do so. It might be possible, if the people didn't have to spend hours in line for basic necessities.
