goodells··on Simone Giertz – Back from brain surgery [video]
The whole system is awe-inspiring. Have a medical emergency? We'll send a several-ton box on wheels speeding your way within minutes. If you're in a city, the traffic lights will turn red as the emergency vehicle approaches to make passing safer. Paramedics trained in evidence-based pre-hospital medicine will perform the interventions most likely to save you based on their field impression.

And when you arrive at the hospital it gets really cool - at a level 1 trauma center, they should be prepared to give you a CT scan and treat you in 10 minutes or less. That might involve snaking a tiny wire through your arteries all the way from your leg to your head, or administering one of thousands of drugs that has exactly the desired effect.

It's easy to take it all for granted but the technology and systems in place to take care of us are amazing.

goodells··on 2018 MacBook Pro Has Fastest SSD Ever
I wonder if this could be used to infer information that users may not intend. For example, perhaps copying a file and fraudulently altering something in it at a specific time could be used as evidence in a trial.
goodells··on Ask HN: How do I cope with being a young diabetic?
Hey, I'm sorry to hear about your situation - to be honest it sounds stress-inducing on its own.

Your question is vague considering the type of advice you're looking for. What is your living situation like? Do you have any immediate concerns? Besides just general "stress", what bothers you the most? If you're willing to share, how recent is your diagnosis?

One overall suggestion I have for you is to not psych yourself out. If you convince yourself that you have a low stress tolerance, you will. Having a medical condition that is exacerbated by stress is legitimate, but if you avoid all stress and never develop coping mechanisms then you will be worse off. If you notice yourself stressing about stress itself, just take a deep breath (I mean physically stop what you're doing and breathe in and out over the course of several seconds) and find out what's really bothering you.

In terms of your health, you should find a good endocrinologist if you weren't referred to one already. This isn't meant to be medical advice, but type 2 diabetes is curable. It tends to be easier to cure if you take care of it sooner rather than later though, and after 6-7 years it is effectively permanent. A young person with the condition should be able to gradually lower his insulin resistance and become healthy again if he treats it as a priority.

My background is in healthcare and computers - if you are in the United States and need help with health insurance or Medicare I can look into it: sam (at) mangane.se

goodells··on Big Tech’s Hot New Talent Incubator: Community College
I just finished my undergrad at a traditional four-year university in the United States and this is spot on. The language problem you mention is very real - I have taken classes with professors who are almost incomprehensible when speaking English. In some of my computer science lectures it was not uncommon for a student to ask the professor a question and for him to answer it in a language other than English, which doesn't seem fair.
goodells··on Strapdown.js – Instant and elegant Markdown documents
This is awesome, I had no idea you could use Chrome to run a webpage with JavaScript and dump its contents. Thanks for sharing!
goodells··on Scan technique reveals secret writing in mummy cases
Why can’t we just put the mummies through a CT or MRI scanner? If the ink used in the writing found here or other components deeper inside the artifact have different densities, a CT scan could detect that and pose no harm to the specimen. Assuming no metal is used in the mummies, MRI or MR spectroscopy could potentially give more insight into chemical composition and differentiate isodense parts.
goodells··on Sugar alters hormones and metabolism, sets stage for obesity and diabetes
This sounds very interesting as another metric (like weight on a scale, as you put it) for someone trying to be conscious about their health. Is this something that a person could do cheaply at home with over-the-counter diabetic testing supplies? Could you be more specific or link to something about a protocol for e.g. measuring the effect of a meal on blood glucose and how to interpret those results?
goodells··on Using chatbots against voicespam: analyzing Lenny’s effectiveness
I don't have an opinion on this technique with ads vs. calls, but ads are transactional. You get some piece of content or an app in exchange for your attention, usually initiated by the user, and with low friction to close the tab or uninstall the app. With calls, the moment it rings you are interrupted, the other party reached out to you, and you get absolutely nothing in return for your wasted time.
goodells··on Ask HN: Urgent – Where to Find Chicago Food Supplies for Hurricane Irma Relief?
This might not be the answer you expected, but I would highly recommend looking into the resources that The Church of Jesus Christ of Latter-day Saints has available in the Chicago area. The Mormons have locations known as Home Storage Centers[1] where members can buy non-perishable food items in large quantities at low prices so they and their families can be self-reliant. They are generally open to non-members using the facilities if they ask first, and for your cause I would be very surprised if they would not support you wholeheartedly. There is one less than an hour outside of Chicago[2].

If you need a member of the church or the bishopric (clergy) to vouch for you, please feel free to get in contact with me at sam (at) mangane.se.

Good luck!

goodells··on A Concise History of Asperger Syndrome (2015)
The person you're replying to may be referring to the fact that DSM-5's diagnostic criteria for Autism Spectrum Disorder exclude a large number of people who would formerly have qualified as having Aspberger's Syndrome. TFA also talks about how some prefer to keep the AS label vs. ASD.
goodells··on Warming to boost deadly humidity levels across South Asia
The problem is not that humidity will increase. The article explains that the human body's ability to dissipate heat into air that is both hot and humid decreases significantly around 35C.
goodells··on How an ex-FBI profiler helped put an innocent man behind bars
I agree that the victims of false imprisonment deserve a heck of a lot more than they get now, but one thing to consider is that mandating things like this may lead to fewer convictions being overturned due to the costs it would incur. It wouldn't help at all if the requirements just keep more innocent people in prison longer.
goodells··on Show HN: ProximityHash – Geohashes in Proximity
I'm a bit confused about the "hash" part of this... wouldn't you want to be able to go back from the hashed string to the original location? I can't think of much of a use for only being able to test locations to see if they match a proximity hash.

Internally, the space-filling curves are super interesting. I highly recommend this writeup [1] on how they're used in things like planet-sized maps. I've heard rumors that Google adjusts the offset of their space-filling curves to minimize large discontinuities near land and push them over the ocean instead.

goodells··on What happen to your source code and database when you die prematurely?
The best solution will depend on your needs and the specifics of the situation, but one alternative to a dead man switch is to have instructions or credentials that require multiple trusted people to access. If you are paranoid you can choose people who don't even know each other, or give yourself the option to cancel the release of the information with a dead man switch with a shorter duration. It'd be a shame if such a complicated system that isn't tested much were to fail, though...
goodells··on Practical Color Theory for People Who Code
I just wanted to say that the diagram of the transformation from RGB to the different color models is absolutely beautiful as well as informative. When I have a free day or two I am going to have to put together an animation for it where you can track a given color through the process. My favorite class in university was about color models, all the way from CIE 1931 to the various transformations on it to match human perception and driven by anatomical insights about the human eye. It's fascinating!
goodells··on Healthy California Act: proposal to make findings about single-payer healthcare
In a single payer system, there wouldn't be an insurance company sitting between a patient and the medical provider, extracting rent. The middleman and associated overhead would not exist (or be centralized), which could make the market more efficient.
goodells··on I Rewired My Brain to Become Fluent in Math (2014)
I'm a student in university now, and I can relate to your experience.

What helped me a lot as a kid was being motivated to learn things when it didn't seem like "learning". For example, I was able to get the hang of programming by playing a game that incorporated it, and it succeeded because it got me excited about doing cool things. Maybe this kind of "gamification" could be more useful than just adding points and rules to things to make people compete.

goodells··on The Cost of Native Mobile App Development Is Too Damn High
I would argue that in some cases (certainly not all), a little bit of strategically placed "wow" may be vital for some startups to grow - small things that make users love a product and show others. The vast majority of users will not sympathize with the reasons a developer would choose to use something like a web view in a native app.
goodells··on UDP vs TCP
Yes! His writeups on networked physics were extremely lucid and easy to follow. The way that he focuses on minimizing the bandwidth with bitpacking and goes from something absurdly large to equally absurdly small was a mesmerizing read for me as a programmer just getting started because of an interest in games.
goodells··on Diabetes, heart disease, and back pain dominate US health care spending
These diseases are all symptoms of one somewhat obvious underlying cause - obesity (which of course has its own causes). I wonder if more aggressive preventative care will be seen as cost-effective by insurance companies soon - it's already taking place in workplaces that offer insurance and give a stipend to employees to spend on e.g. a gym membership or group exercise sessions.
goodells··on Ask HN: Train your own text to speech voice?
This isn't exactly a productive comment, but I just wanted to say that it's extremely thoughtful to do that for the elders in your family, and I'm sure they would appreciate it immensely. Now that you've given me the idea, I want to do this for my grandmother while she is still in good health. Thank you!
goodells··on Simplex-noise.js: A fast simplex noise implementation in JavaScript
It's really interesting that they were able to use typed arrays to get better performance out of it. If anyone is looking for a more bare-bones approach to simplex or perlin noise, I've had good experiences with this library:

goodells··on Security Risks of TSA PreCheck
I find it difficult to believe that the bureaucrats that came up with this couldn't recognize the gaping hole and inconvenience that TSA PreCheck is. This could be interpreted as some acknowledgement of the security theater they're putting on, indicative of poor management/internal lack of faith at the TSA, or some combination of both.

As an aside - I've never had the opportunity to rant about this before - the Dane County Regional Airport is laid out in such a way that there are two escalators that go up to the security checkpoints on the upper level, one on each side of the ticketing counters. One is TSA PreCheck, the other is not (yes, entirely 1/2 of the locations they have available are TSA PreCheck, and there are always lines at the other side). The signage is very poor and many, many people end up going to the PreCheck side, get turned away, and then need to walk 10 minutes to the other side of the airport to go through the regular lane. Of course this could be avoided if you enroll in that program, but for people who travel by plane infrequently, the cost/benefit ratio just isn't there.

goodells··on Plain Text and Google Keep Is a Killer Combo for Notes and Organization
Google Keep is a great little thing for small lists that get tweaked often, like things to do, daily objectives, shopping lists, etc. The web version is quite nicely made and suitable for avoiding distractions.

The only qualm I have with it is the lack of any official or half decent iOS app, which is understandable, but also indicative of where the service stands in Google's playbook.

goodells··on Elementary OS
I've used elementary OS for a few months now as my primary development environment. It's great to have set up in VirtualBox on 2/3 monitors, and the fact that it's based on Ubuntu makes finding support online pretty easy for someone not as experienced with Linux.

My biggest complaint is actually that the OS file selection interface (like what I get opening things in Sublime Text) is not same as the fancy finder application, but the default Ubuntu one that doesn't look consistent.

goodells··on It Costs $30 to Make a DIY EpiPen
Government 'greed' may not be the best way to put it, but there is something there. This extremely high barrier to entry may not be completely necessary, and in some cases may be interpreted as deliberate suppression of competition effected by vested interests in the pharmaceutical and healthcare industries. If such a product can be proven safe using the same active ingredient and a comparable delivery mechanism, it shouldn't require millions of dollars to be approved.
goodells··on Do not let your CDN betray you: Use Subresource Integrity
This was my first thought as well. Why go through the trouble of redundantly fetching a resource by URI and verifying its checksum when you could just use a system designed for this in the first place?
goodells··on Tsunami alert as Chile hit by powerful earthquake
The consolidation and eventual application of data generated by government agencies like the USGS should be at least someone's goal, maybe the US Digital Service. Although probably not as big an issue in the continental United States as elsewhere, a 21st-century augmentation to traditional warnings of earthquakes/floods/tornadoes should be a thing if it isn't already.
goodells··on Hawaii Bans Non-Compete and Non-Solicit Clauses in High-Tech Employment
I don't think that the explanation is so simple.

A different way to put it would be that it is based in the way that U.S. law allows you to sue anyone for any "damages," real or imaginary, only proving that you got hurt. Any potential employee can have an idea that is derived from trade secrets or other material not meant for people outside of an organization, and it's not possible to simply turn off this ability or create a distinction between ideas that are completely independent from that information or not. Because of this, it's possible to incur some level of damage to an employer with an idea that was technically had at any time of day.

goodells··on Chile is introducing free higher education
The German school system divides students into three distinct groups starting in the fourth grade, meaning the decision is made in the third [1]. The three divisions are 1. Hauptschule (central, lower-level school) 2. Realschule (technical school) and 3. Gymnasium (uni-prep school). Once placed into one of these three tracks, it's very difficult to switch between them - more so in the later years, since they each have a different number of years required in order to graduate.

Over the past few years, the system has been changing to allow parents greater say in their children's future, resulting in the same mixups that happen in the United States when parents can override course placement decisions. I can go into more detail on this if anyone wants.
