smanuel··on VR-based brain training for ADHD
IMO controls are genuinely hard in AVE/VR studies. There isn't an obvious "inert" placebo, no light/sound removes immersion, random flashes or audio still affect arousal, and even "wrong" frequencies can entrain.

VR-only controls help, but don't isolate sensory stimulation. That's why many early AVE studies use pre/post designs and treat results as exploratory rather than definitive.

smanuel··on VR-based brain training for ADHD
You can check out this VR app, it's pretty good: https://sidequestvr.com/app/2054/visitations

As for binaural beats and isochronic tones, it's all about using the right frequencies, how you transition between them, how you combine tones or beats with other music or sounds, the carrier frequency, how you synchronize lights with the tones or beats, and so on.

smanuel··on New batteries could make phones, drones, and electric cars last twice as long
Lithium-sulfur batteries look like the most possible candidate as the next incremental evolution of the lithium ion batteries. Lithium metal... not so much.

But I really hope for revolution in this space, rather than incremental changes. This will boost and give wings to so many other inventions.

smanuel··on MongoDB queries don’t always return all matching documents
> If you have a lot of relations in your data don't use mongo, it's just hype. You will end up with collections without relations and then do joins in your code instead of having db do it for you.

So... you are not against MongoDB but against NoSQL in general? I've used MongoDB and I've never ended up with lots of joins in my code. But I guess it all depends on the use case and how you've structured your data. Document databases are not a silver bullet.

smanuel··on Microsoft Acquires Xamarin
What's interesting about Xamarin is that they are very local about OSS (Miguel) but what they did was not very "open sourcey" - obtaining a perpetual license for Mono and this way making sure that no one else can put Mono on Android / iOS. Ever.

And then charging 1000$ annually per developer, per platform.

On the other hand they've made something that developers love (from what I've heard, I've never used Xamarin's stuff personally) so they deserve the credits.

Congrats to the team.

smanuel··on Brave: Brendan Eich's clean-ads browser startup
Someone should make a browser that blocks "Ev­­­er­­­yb­­­od­­­y c­­­an e­­­ar­­­n xxx$+ da­­­il­­­y... Y­­­o­­­u c­­­an e­­­arn f­­­ro­­­m ..." spam comments. I think I've seen those mostly through the FB comments plugin. Obviously FB can't / doesn't want to fix that.
smanuel··on How one woman made a ‘tricorder’ that could change medicine [video]
Even with the blood sample "shortcoming", it will be huge if it keeps to its promise.

But I learned not to get excited by new medical inventions before a few years pass, before it's FDA approved, before there are enough studies that prove it really does what it says it does, etc.

Cool video. A woman writing some formulas, nano technology, DNA sequences, etc. All cool stuff.

Theranos also had some cool stuff to show but...

smanuel··on Humans are not unitary individuals but superorganisms
All of humanity's scientific progress has been built gradually upon principles, that have been the same for ages. Start experimenting with the fundamentals and you start wandering in a sea of abstractness - holographic universe, multiverse, one-electron universe... you name it. Theories that you can either prove or disprove and theories that bring no progress.

That's just my opinion of course.

smanuel··on Humans are not unitary individuals but superorganisms
> They're real, like, but not really real, you know what I mean.

You mean.. the real reality? The reality that can't be easily explained through observation and empirical evidence? The reality that can't be perceived through our basic physical senses? The reality where causation and correlation don't mean a thing? If you mean that reality... there's no such thing, and even if there is, there's no point in talking about it, it's way beyond our reach.

If you mean the reality in which we've done most of the division and classification work very poorly due to lack of data... I know what you mean.

smanuel··on Introducing PaaSTA: An Open, Distributed, Platform as a Service
> but to people who want to build their own PaaS for their internal developers

I don't understand this. Can you elaborate?

smanuel··on Introducing PaaSTA: An Open, Distributed, Platform as a Service
> It is not optimized to be simple to deploy for operators. [1]

Isn't the whole point of a PaaS to be easily deployable so that I don't have to learn a bunch of other tools, that depend on a bunch of other tools, that... You get the point.

smanuel··on West Virginia Engineer Proves to Be a David to VW's Goliath
I mentioned this mostly as a reply to:

[3]The caveat is that petrol gas emits particulates at a smaller micron level, unnoticeable to the naked eye, and may actually be of greater concern to the general public.

The diesel exhaust fumes are proven to be worse than the petrol engines in at least one respect - health.

Maybe if every truck on the road and a lot of the cars ran on bananas and not on diesel, then I would be concerned about the radiation levels in bananas.

Moreover in the place where I live people are allowed to remove their car DPFs which makes things even worse.

smanuel··on New Technique Can Efficiently Detect All Known Human Viruses in a Blood Sample
Well actually for 2015 FDA has approved 96% of the new drugs [1] so it's not the same old tough regulator it's been before. Or maybe it's just tough for things that work and allows things that shouldn't be allowed [2].

smanuel··on Soylent 2.0
I'm amazed by how FDA regulates drugs and how it regulates... actually how it doesn't regulate, supplements and things like Soylent, which is not even a supplement but claims to be food "that possesses all the essential ingredients a body needs to be healthy".

Studies anyone?

Maybe it does contain all the essential ingredients but maybe the human body can't process them effectively. Maybe it's not very healthy taking all these ingredients every day.

Maybe in the long run it'll have bad effect on the microbiome, intestinal mucosa or on million other things in the human body.

Whenever someone question those things, the answer is "But it's better than junk food". Well...

Edit: Ok, my bad, it's actually regulated as a food [1].

Google, you can take 127.0.0.1 down, but please leave localhost alone.
smanuel··on The man who saw time stand still
This reminds me of Gurdjieff and Ouspensky's teachings about self awareness [1].

I highly recommend Ouspensky's "In search of the Miraculous". Well, you can skip / disregard the esoteric bs if you want.

smanuel··on Apple Removes American Civil War Games from the App Store
Well, I guess that's a very delicate subject to talk about.

In Wolfenstein 3D you can't play a nazzi shooting Americans (for example). You play the good guy shooting the bad guys.

I also don't think the problem is the flag. IMO the real problem is that in most of the games you can play on both sides. Kids can easily start identifying themselves as the side on which they play and forget the important details. Like... history.

"All animals are equal but some animals are more equal than others."

Shocking news.

smanuel··on Introducing Empire: A Self-Hosted PaaS Built on Docker and Amazon ECS
> We tried Deis briefly but ultimately decided that it was more complicated than we felt it needed to be.

That kind of reminds me of https://xkcd.com/927/

Sorry if that's not the case. I've also played briefly with Flynn and Deis and I haven't found anything that complicated that would need a whole rewrite and changing the entire approach. Moreover with Deis I can easily change providers (DO, AWS, Azure, etc.) and with Emprire I'm bound to ECS. At least that was my first impression, I have to read more.

smanuel··on The average American woman now weighs 166 pounds – as much as a 1960s man
Very nice reading on PR. Thanks for sharing.

The problem with unlimited information - it's getting harder and harder to tell what's good and what's bad for you:

http://www.vox.com/2015/5/13/8591837/how-science-is-broken

Take a look at the chart that's titled "Everything we eat both causes and prevents cancer". A picture that's worth a thousand words.

We need better science. But I don't know how that's going to happen.

smanuel··on Long sentences
Disclaimer: I'm not a native English speaker.

Sorry but IMO the author has failed to prove his case. The text is not easy to read, and it's hard to follow the author's thought.

So long sentences and long paragraphs definitely don't help. It's either that or I should get tested for ADHD.

smanuel··on The media loves the Gates Foundation. These experts are more skeptical
> if they decide to pull the plug on certain projects, those projects are going to have a very tough time.

That looks like a problem to me.

Also, I'm not sure how the whole system works, but let's say I'm a medical researcher. I may be tempted to focus on researches that get money easier (e.g. what gets funded easier by the Gates foundation), instead of focusing on something else (e.g. cancer research). Suddenly the Gates foundation dictates the trends.

That's really some simple thinking here but seems like a valid point to me. Still, I could be totally wrong. I'm not a medical researcher.

smanuel··on The media loves the Gates Foundation. These experts are more skeptical
Well, the writer acknowledges what the foundation has done and how much it's helping with certain diseases and problems, but still the concerns it's trying to raise seem valid IMO.

smanuel··on Show HN: An Isomorphic JavaScript Framework Faster Than React
That comment!

That's exactly how I feel about every new js framework popping out from nowhere.

But I accidentally clicked on the title. The site looks cool and guess what, a framework which is faster that React and doesn't make you put xml in js.

And it grabbed my attention. I don't know whether I'll ever use it but it will be on my radar for sure. Especially if they don't lie about how fast it is.
