nateberkopec··on Transparent Hugepages: measuring the performance impact (2017)
Worth noting that the main reason Rubyists are disabling THP is memory consumption, which is something the author didn't measure.
nateberkopec··on Dogs demonstrate the existence of an epileptic seizure odour in humans
As a search and rescue volunteer, I have had a number of fascinating experiences with trained scent dogs. I thought scent dogs only really worked in the movies, but watching them work to find humans lost in the woods was an eye-opening experience.

I watched a dog in training follow a 1km scent trail that was several hours old. This dog was not even fully trained for the activity and followed every footstep to the subject.

They really do navigate with their nose, as well. I was the subject for another exercise, and I watched a dog look almost straight at me, not see me, then pick up my scent and follow their nose straight to me.

nateberkopec··on Online activists are silencing us, scientists say
I used "you" in the wrong way here. You == qualified medical people, such as in the article. Not you == oneself/one.

> Once I realized this, it never came back again.

This was the same for me with RSI. It was simply the act of realizing it was psychosomatic and caused by stress that made it disappear completely.

I completely agree with you, but our society has such a stigma around mental illness that if you tell someone their back pain is caused by repressed emotions, you get what happens in the article.
nateberkopec··on Online activists are silencing us, scientists say
Over the next 20 or so years, expect a lot of syndromes/conditions to be reclassified, as Michael Sharpe puts in the article, as "biological condition[s] that can be perpetuated by social and psychological factors.".

I struggled with RSI for a couple of years until I read John Sarno's "The Mind-Body Connection" on the recommendation of someone from HN. Sarno's thesis is that many chronic pain conditions (those without a clear physical mechanism, such as RSI or chronic back pain) are psychosomatic.

A lot of people struggle with this idea, and take it, as they did in the article, as "my pain isn't real". Sarno's book very clearly lays out that the pain is real, it's just caused by processes in your brain, not the rest of your body.

Societally it's all very strange. We accept a "mind-body" connection for certain types of disorders, but, not for others. Anxiety sufferers can fool themselves into thinking they're having a heart attack and hyperventilate. Why is it crazy or anti-scientific to think that the same can cause other symptoms? We've searched for decades for body-based mechanisms for these chronic pain conditions, why not consider causes in the brain?

nateberkopec··on Capitalism and Inequality
FTA:

>I also understand that government is bloated and there are many places where we could cut spending

The problem with this critique (the right-wing rallying cry since at least Reagan) is that no one ever wants to cut any particular program (which Fred acknowledges later in his charter school story). The right in the US, for example, bemoans government spending every year, then doesn't cut any spending, raises military spending, and then cuts taxes. Again, Fred acknowledges this, but doesn't take the next step of doing the unpopular, hard work of deciding where we can size down. I'd like to hear exactly what spending Fred thinks we should cut, otherwise this position is pretty empty.

> If we were to force it to go through the same technological revolution that the private sector is going through, we would see massive efficiencies

Again, this is what the Republican party has been saying for 30 years, but has been unable to deliver. We can say we want "more efficient government" until the cows come home, but there is something in the system that is preventing us from doing so. What is that thing? Let's talk about that. Otherwise, this post is just a rehash of Republican talking points and slogans, without any real proposals.

nateberkopec··on A Harvard Astronomer on the Interstellar Object ‘Oumuamua
What's the future for the study of Oumuamua? Apparently, it should be beyond the orbit of Saturn by the end of this month. Will we _ever_ know what it is definitively, or is it too late?
nateberkopec··on A Harvard Astronomer on the Interstellar Object ‘Oumuamua
It is not beyond our ability, as "detecting earth-sized planets" was the explicit mission of the Kepler spacecraft.
nateberkopec··on Fleets of drones could aid searches for lost hikers
The video assumes that the most important and most difficult part of a SAR drone's job - object detection - will simply be solved at some point in the future.

I am a SAR volunteer, and our team has used drones on real searches. What I can tell you is that the problem is not navigation (even through forested areas), but object detection. Even for a human being, detecting humans (responsive or unresponsive) or signs of human presence (trash, abandoned camps, etc) from drone camera footage is extremely difficult.

Autonomous flying drone navigation is hard but identifying signs of human presence from onboard sensor information will be much, much harder.

nateberkopec··on Upgrading GitHub from Rails 3.2 to 5.2
Let me get this straight: you're arguing that a 10-year-old top-100-in-the-world website taking 4 full-time engineers and having them upgrade their core framework 2 major version over 18 months is some sort of massive failure, and that failure would be solved with static types?

Also, you're saying that Github hasn't added any new features in the last 18 months?

nateberkopec··on Facebook Is Letting Job Advertisers Target Only Men
> Would this be different if, for example, Facebook was targeting people for job ads based on "people who like action movies" or "people who like romance novels" (I'm stereotyping here, but just assume you pick a category that ends up being a decent proxy for gender)?

No, this would still be illegal (in the US, anyway). The only difference is that Facebook wouldn't be aiding/abetting an illegal hiring practice. Employers can and have been penalized for hiring from homogenous applicant pools.

nateberkopec··on Ask HN: What are some niche communities you enjoy?
I love Forgotten Weapons. I'm not even a gun nut, never owned one, but something about watching him explain the history and mechanical functioning of each firearm is so relaxing and satisfying.
nateberkopec··on As Economics Improve, Solar Shines in Rural America
My local co-op has committed to providing 100% of sunny daytime electricity with solar by 2022 (35 megawatts): http://kitcarson.com/electric/100-daytime-solar-energy-by-20...

It's really interesting that the push is coming from co-ops. Many people in my town don't seem to understand how important and incredible our local co-op is. They mostly complain about the quality of service (there's more downtime than you would get from a traditional utility, for sure) but don't think about the alternative is a utility that belches coal smoke and outsources customer service to Bangladesh.

nateberkopec··on Apple sets up iPhones to relay location for 911 calls
FYI, most US SAR teams use websites which basically just call "getCurrentPosition()" to get GPS coordinates from lost subjects. i.e. they leave a voicemail/text subject with a link to a website, and they can push a button on that site to send coordinates from the Geolocation API to SAR.
nateberkopec··on Community-Owned Fiber Networks: Value Leaders in America
I live in a rural town in New Mexico of about 10,000 people. We get 50 megabit symmetrical fiber from the local co-op for about $60 a month. I think the fiber was funded by a USDA grant.

One of the nice things is not having to deal with big-co customer service like Verizon or Comcast. You call up and you get a real person who lives in your town.

nateberkopec··on Ranking Some Generals in the History of Warfare
Not sure the intent of the author was to cover operational-level commanders. Even if Gulf War I did count, coalition forces outnumbered the Iraqis in sum total, so Schwarzkopf's WAR probably wouldn't be very good.
nateberkopec··on Ranking Some Generals in the History of Warfare
This is really neat. I love the idea of applying sabermetrics to historic generals.

However, one failure of this approach is that it assumes that the numbers of soldiers given for ancient battles is accurate. The Greeks will tell you that the Persians came with millions of soliders, but that just wasn't even possible given the state of military logistics at the time.

So, look at the #4 general in the article, Khalid ibn al-Walid. As an example data point, the article on the Battle of Yamama (https://en.wikipedia.org/wiki/Battle_of_Yamama) says he fought at nearly a 4:1 disadvantage, and as far as I can tell, the only source for these numbers is the Quran. Much like how the Greek sources love to tell you how big, bad and numerous the Persians that they defeated were, how great is God's glory if the army of God is steamrollering equal or smaller size armies?

I'm not sure how the author could account for this. IMO this underweights more recent and well-attributed generals such as Napoleon or Wellesley.

nateberkopec··on Apple’s Secure Enclave Processor (SEP) Firmware Decrypted
The link makes it sound like SEP only handles TouchID - is this true, or does the SEP also deal with passcodes?
nateberkopec··on Why Ruby App Servers Break on MacOS High Sierra
In Puma, we emit a warning if we detect any additional threads running prior to fork.
nateberkopec··on Google's 'Advanced Protection' Locks Down Accounts Like Never Before
Ah yes, a hacker organization which does things like create Android malware to disable Ukrainian artillery and attempts to interfere with American elections is probably not a Russian front. Come on.

Dell SecureWorks and the CIA have presented plenty of evidence that this was a Russian-backed group, probably GRU.

EDIT: Also, even if there aren't lines in their malware which say "(c) GRU 2017", Fancy Bear is a group which consistently targets enemies of the Russian government. They don't steal credit card numbers, they commit digital terrorism that furthers Russia's interests. It doesn't really matter if they're 100% state-backed or not, because they clearly and consistently act in the Russian government's interests. An organization which hacks targets that benefit Russia and a Russian gov't hacking organization are the same thing from the perspective of the United States.

nateberkopec··on North Korea Missile Appears to Have Flown Over Japan, Abe Says
Anti-missile defense systems on the ballistic scale are pretty much a 50/50 proposition. There's signs they may have been testing multiple re-entry vehicles as well, which makes it even more difficult.

But just because anti-missile systems weren't used here doesn't mean they don't exist. US/Japan could have decided the missile was probably headed for the Pacific and decided not to intercept. The location and capability of US anti-missile batteries would be strategically useful information for NK, so better to keep them quiet if you don't have to use them.

nateberkopec··on Summer Reading List
I'm in the "it worked for me so I don't care camp".

I can't believe people think it's woo-woo or anti-scientific, though, after reading it. Sarno's thesis is basically "we haven't found a physical cause for most chronic pain conditions, so why not the brain?".

Anxiety sufferers can fool themselves into thinking they're having a heart attack and hyperventilate. Why is it crazy or anti-scientific to think that the same can cause other symptoms?

nateberkopec··on Summer Reading List
Reading Sarno's book cured my RSI and my friend's RSI as well. If it works, it's not stupid.
nateberkopec··on The Worst Internet in America
I moved to Taos, New Mexico last year after 8 years in NYC. Taos has about ~5,000 people. I'm a freelance developer and author.

It's one of the most beautiful places in America, in my opinion. There's arts, culture, and incredible access to the outdoors. I ski all winter.

The internet is actually pretty decent here if you're in the right part of town. Some people have fiber.

nateberkopec··on Did Airbnb Kill the Mountain Town?
I moved to Taos, New Mexico last year, a ski town with a huge Airbnb market, like Crested Butte. It has definitely increased long term rental prices around here, but, to a former NYC resident like me, they were pretty low to begin with.

Taos, thankfully, has a lot of factors which prevent it from becoming the next Jackson Hole or Crested Butte. For one, unlike those towns, we have a lot of land. Taos isn't really hemmed in by National Forests and has plenty of room for new construction. Second, Taos was fairly large to begin with: 15,000 people or so in the greater area, so Airbnb has a more muted effect.

It seems like a very mixed bag to me. Long term rental prices keep going way up, but many locals seem to be making a lot of money renting out (of course, only the ones who can afford to own in the first place). The city also seems to make a decent amount of money from lodgers tax as well.

nateberkopec··on How Discord Scaled Elixir to 5M Concurrent Users
If you have a share-nothing architecture, then yes, any language can scale to any load, some with more hardware than others.
nateberkopec··on Is Ruby Too Slow for Web-Scale?
I cited decades of human-computer interaction research that disagrees with you.

EDIT: also, that paragraph is purely discussing the response times for producing the HTML document of a web application, not, say if you added 100ms lag to every JS response (which would compound, like you say).

nateberkopec··on How To Go Viral By Using Fake Reddit Likes
Yeah, I don't experience a lot of obvious shilling on Reddit, but I've unsubscribed to most of the default subs and mostly just read small subs relevant to my interests.
nateberkopec··on What is an Initial Coin Offering and How Does it Work?
The fact that this is on "fxempire.com" is really all you need to know, isn't it?

FX trading and daytrading are two forms of legalized gambling for the upper class, so it makes sense that the same crowd will be interested in cryptocurrency. Such people are generally aware they are speculators and participating in a high-risk activity, so, fine. But what I worry about is the "dumb money" that follows. I saw Twitter ads for a "Bitcoin IRA" today. If you're putting your retirement savings in Bitcoin...
