david-cako··on Apple iOS Background Tasks
Background transfer service could do this. Also, background fetch and background notifications both allowed arbitrary background execution, but only up to 30 seconds.

This feature replaces background fetch.

david-cako··on How Much Alcohol Is Safe to Drink? None, Say These Researchers
My theory/rule is that drinking 3-4+ in one session is what causes liver damage, and your body is otherwise able to recover from 1-2 drinks (and also not build tolerance).

I have no data for this however it is consistent with my preference for moderation.

What you described sounds like a lot, and it doesn’t sound like it allows for recovery.

david-cako··on Why the Flow of Time Is an Illusion
I find kabbalah very interesting, because this assertion has been made for a long time without us having something tangible to compare it to. Now we have computers, basic AI, and no signs of slowing down. What if kabbalah, or something similar, is actually how consciousness emerges across different types of observers? I.e., consciousness is a "most likely" pattern that emerges from the initial ability to conceive of time.

Tarot is an example of a more personified version of the same archetypal phenomenon. The first few cards are indicative of susceptibility to experience, concentration of experience, awareness of experience, multiplicity of experience, and mastery of experience.

david-cako··on Why the Flow of Time Is an Illusion
Very Jungian/Jordan Peterson-esque thought that I think makes a lot of sense in understanding ourselves. Also reminds me of the book The Righteous Mind.

We exist to measure ourselves in an ocean of complexity, with infinite recursion in self-awareness.

david-cako··on Why the Flow of Time Is an Illusion
I also often consider that each day I wake up as an observer to a linked list of time, that exists independently of me yet to me "only" in my mind. As our eyes and ears are sensitive to fine vibration around us, so it seems that consciousness is sensitive to time.
david-cako··on Changes to Models S and X allow them to travel longer without larger batteries
There was a twitter chain posted here about a year back where someone described how convoluted getting a Tesla off the factory floor is. All of the systems along the way have to be installed and flashed in a particular order to ensure nothing goes belly up.
david-cako··on Why Do People with Depression Like Listening to Sad Music?
The album Lateralus by Tool goes a step further for me. It strikes a balance between depressed and optimistic unlike any other.
david-cako··on Apple’s $9 engineering marvel no one wants (2017)
I like USB-C, lightning, and the new keyboards, although losing magsafe sucks. Having dockability baked into the format is great though. If they move everything to USB-C they will have me satisfied.

The dongles are whatever. I’m not convinced I need permanent ports when I’m not at my desk. Losing the iPhone headphone jack is only an inconvenience when I’m negligent about plugging my phone in and am traveling. I airplay to my receiver at home. I started using a different pair of bluetooth headphones when on the go, but the headphones I actually like, 598s and 579s, are wired. The dongles are priced right. If they were $20 I’d be more upset.

The keyboards were most surprising; as a mechanical keyboard guy, a few months and I’m finding it’s quicker due to low travel and more predictable action. I don’t even have a separate keyboard on my desk now.

I think people just underestimate the big picture benefit of letting Apple shepherd you into the experience they have designed. To them, “everyone” uses bluetooth, so the jack is irrelevant. For me, as someone who REALLY likes my wired headphones, I still get it. The seamless bluetooth experience is nice in and out of the car and traveling.

They make a top level decision like “slim, quiet keyboards!”, “no more buttons!”, or “one cable!” that is appealing to investors and consumers and stick to it. The fact that they are the only brand that seems able to strongly execute on these types of unified schemes, often requiring partners to architect to a specific API (airplay and homekit, for instance) could be proof that the only way to do that is with a lot of steam behind you and strong opinions behind design choices. I cannot wait for what is next in terms of mac/iOS unification.

david-cako··on Melatonin's Effect on Skin and Hair
This is what worries me about sunscreen. This is an entirely non scientific concern, but sunscreen is as much of a business as antiperspirant and shampoo, and both of those things disrupt normal endocrine rhythm, by definition.

Like even if the mechanism of action is perfectly sound, how does your body adjust with that over many years?

david-cako··on The New 30-Something
>I made it out and got a nice job in tech, but like many of my peers it is I who support my parents. I pay their health insurance, I lend them money for groceries, and I'm financing my dad's chemotherapy. Do you know how hard it is to save up for a house (on the west coast !!) knowing you'll never get a windfall from Mom and Dad? When in fact they are a liability budget wise?

I can only imagine how difficult that is. This is an interesting distinction between western and eastern culture too. I wonder if the obligation to take care of your parents is less pronounced in eastern households that are wealthier.

david-cako··on The Rise of the WeWorking Class
Major companies that need distributed workspace for areas that don’t quite need offices, and the “impression” of think tank. They do have cool hosted events fairly often.

david-cako··on The CRISPR Baby Scandal Gets Worse by the Day
This is the point everyone needs to recognize. I predict we will also reach a point where viruses can be engineered, and engineering defenses will be a public health concern.

This is the world to come, and ethics aren’t a viable defense. The gene pool is going to be stirred up in ways we’ve never seen before, and it’s going to be a good reason for us to stop focusing on our differences and start thinking and acting as one species.

david-cako··on Dangerous Ideas
Looking for any and all criticisms! This is something I think a lot about and I think it's a really interesting way of presenting and understanding it -- digging our way into and out of plato's cave as reductionistically as possible.

david-cako··on Why do all websites look the same?
Speaking anecdotally, up to around 2016 every other website used Bootstrap or Foundation, often with minimal customization, just because it looks and works well out of the box on all devices. Now it seems like it's getting better, but generic UI components are an extremely relevant aspect.

Promethease is a good example. Years later a bootstrap website signals to me "it's about the functionality, not the design". https://promethease.com/

Before that everything was jQuery UI. Government websites still use a ton of it. All of Colorado's web portals are built with it. And now things are shifting towards UI frameworks "plus more", like Ionic, which adds a bunch of design/devops workflow and cross platform functionality.

david-cako··on Ask HN: Other online communities like HN?
Slashdot is fun if you want a more cynical take on some of the topics that show up here. Slashdot's articles typically are general tech, science, security, and politics (esp tech related). Here there's more software community stuff, blogs, update notes, personal projects etc. I read both HN and slashdot daily, they each have their own thing.
david-cako··on How Exercise Might “Clean” the Alzheimer's Brain
I think simple carbohydrates are a much bigger silent evil than even alcohol and opioids.

Alcohol and opioids at least have a stigma, and most governments enforce marketing and public health information accordingly. Starch and sugar can never be appropriately demonized because they are "just food", and have some of the largest companies in the US behind them.

The advent of processed food has created 2 entire generations of obese, insulin resistant people. The marketing starts as young as possible, and it is normalized to not think twice about eating sugar all day.

I'm still trying to get over the fact that the FDA actually banned partially hydrogenated oil. Very surprising that they said no to the entire processed food industry in such a big way, to the benefit of consumers. I'm sure the food conglomerates went into it knowing they had other options like interesterified oils up their sleeves, though.

low quality bait
david-cako··on In Praise of Mediocrity
This is a phenomenon I think a lot about -- how globalization and the sheer amount of information we have available requires you to either drastically increase your expectations of yourself or drop them all together.

Think about what being an alpha among a primitive group of humans (or apes) entails. It's part something that is internalized and demonstrated by that individual, and part reinforced socially by the rest of a small group of people who, within the context of the group, plainly recognize that individual as "best". This same dynamic exists for craftsmen among the group, for instance.

Being at the top is always a function of where everyone else on your radar is at. It's just now you have to be your own cheerleader, because it's a much bigger pond.

You have to make calculated decisions about how different things validate you (recreation vs greatness); being great at something in the 21st century really means putting your head down and having an unwavering faith in yourself. You have to keep lifting yourself back up, as the reward is always 10 steps out and always fleeting. At the same time, you now have an infinite amount of resources and inspiration for what you could become. You aren't limited by the nearest available expert, and you aren't limited by your imagination. It's all there for you to pick off the shelf.

david-cako··on Humanoid construction robot installs drywall
A benefit is having a multipurpose robot that can perform a variety of tasks that humans do using similar tools and techniques that we already use. I'm sure there's cases where that makes more sense than having more purpose-built machines.
david-cako··on Go West
Really, I actually love the dry air and am extremely humidity averse. I do remember getting headaches when I first moved here though.

And we'll still be kicking if the rest of the country is underwater; convenient vacationing to the Arizona Bay :^)

david-cako··on Go West
But I love Colorado. The weather is great year round (IMO), tons of sun, even in the winter, which keeps it comfortable and melts the snow quickly. Boulder is also more feasible for commuting than the bay area, allowing you to be removed from Boulder housing prices (which are still not at bay area levels).

You also get a better variety of different people with different attitudes (more so in Denver and CoSp), as compared to the ironically homogeneous bay area tribe. I take an active interest in encompassing as many different things and ideas as possible, and like having people around me that fuel that.

david-cako··on Understanding schizophrenia: What exactly is schizophrenia?
Very true, but I think a neoplatonic view of reality is extremely worthy of attention. The notion that there must be some unifying, self-enforcing, by-definition dissonant/entropic (we're here, aren't we?) oneness that runs through reality, and that the mere knowledge of it lends towards a rationally and emotionally mature wu wei ("effortless doing") sort of existence. Like an infinitely self-referencing stack of the "first principle" unfolding into time, matter, and ultimately reconciled through the cognition of it.

Self-help is one of the best selling genres, yet the most simple of which has been known to man for thousands of years.

david-cako··on Understanding schizophrenia: What exactly is schizophrenia?
My point was that the human experience, all throughout history, hinges on a willingness to identify with deities, so it must be a reasonably effective evolutionary strategy. A deity is the ultimate expression of an applied ethics system, and it seems that in evolving consciousness we tend to unify around cosmological explanations for our behaviors.

Perhaps schizophrenia is a functional mutation that introduces cosmological insight to a group of people; the witch doctor/seer archetype, for instance.

It's obvious that deities are (as of yet) born of un-falsifiable hypotheses, although thank you for pointing that out...

david-cako··on Understanding schizophrenia: What exactly is schizophrenia?
On the contrary, it's possible that transcendent experiences are built into the human psyche, and that schizophrenia-like disorders are examples of the extreme end of suggestibility and ruminative thought -- i.e., an inability to properly interface with subconscious processes.

The brain is a storyteller for the conscious experience, and yet the deeper that rabbit hole goes into creativity and analysis, the more discipline is necessary to turn away from it and delegate to the unconscious.

david-cako··on ReactXP – A library for building cross-platform apps
I think they take issue with the bridge aspect of react-native and with shipping a node binary instead of using the platform's built-in javascript engine (a-la react-native). For instance, <View> would create either an NSView or System.Windows.Controls.Grid using a yet non-existent JS api on each platform, instead of having a bridge that talks back and forth with the platform-native language.
david-cako··on ACLU files charges against Facebook for targeting job ads to young males
You're 100% right, but a business exists first and foremost to make money. No business in their right mind whose customer base is 90% male is going to run an equal amount of ads on TLC as on ESPN. Why should jobs be different?

If I really want to be advertised products marketed to women, what do I do? Turn on TLC, or complain that ESPN isn't showing enough female-oriented ads?

Life isn't fair. Nothing is equal that isn't equal. We can do our best on an individual level but it's unreasonable to expect businesses to do anything more than treat applicants and employees of all demographics equally (which is an ongoing effort). Everything else is a statistic, and businesses will readily graze up against as many rules as possible. The checks and balances of this system is that when a business is caught blatantly discriminating, it turns into national news and they are punished financially.

The upside to this is that ethics and financial interests often align; businesses that are ethical have better public perception, and also attract better employees. Macrocosm and microcosm aligned.

If I wanted to go to nursing school as a male, I'm going to start researching, not wait for facebook to show me an ad.

david-cako··on ACLU files charges against Facebook for targeting job ads to young males
Do you think they are doing this because they want as few women as possible apply for the job, or because they want to maximize the effectiveness of their ad spending? I know which one I'm betting on.

If I'm a nursing school, I'm spending 90% of my marketing dollars on advertising to 18-35 women. Anything else is a calculated attempt at capturing a new market (possibly to fulfill demographic quotas), not arbitrary spending to make sure every demographic on the planet sees the ad.

david-cako··on The Evolution of Reddit’s Architecture (2017)
Slashdot on iOS: no back button, no url bar. Perfectly unusable.

No idea why they don't remove the web app meta tag. It's terrible. Slashdot is literally unusable if you add it to your home screen.
