xorxornop··on What If Time Really Exists? (2008)
Check out arXiv:1405.1548v3

The Cellular Automaton Interpretation of Quantum Mechanics Gerard ’t Hooft

The author is very far from a crank, too, being one of the most important influences in the Standard Model...

xorxornop··on The PC is interesting again
There's another factor, though, which you missed entirely: larger SSDs have muchz much faster write speeds, and also read speeds. The parallel NAND chips provide a sort of intra-device RAID
xorxornop··on Show HN: Alacritty, a GPU-accelerated terminal emulator written in Rust
FPS or more strictly, DUPS (display updates per second), as a function of resource use - that is, what pushes the most text, the fastest, with the most displayed frames (sent to actual display/monitor) corresponding to discrete states of display output (v vis-à-vis the terminal), per second?

Some terminals bottleneck standard out ️ display , some hardcode the display rate

xorxornop··on Nvidia and Audi aim to bring a self-driving AI car to market by 2020
We often don't even have appropriate language for many decision processes. See: research into those that do vs. don't have internal monologues (virtual voice, basically) when reading and thinking, and associations to creative thought.

N.B: When I was younger I had no idea that others did those and thought they were fucking with me when they were describing this.

It'll be that way at first, yeah, but once it becomes obvious how much better the AI drivers are, it will start to become irresponsible to not use it
xorxornop··on The Cost of Native Mobile App Development Is Too Damn High
No love for Xamarin?

Being able to target Android/iOS[/WP, relevancy aside] (and UWP in part, with a shared logic codebase), is pretty nice. I rather suspect it will get full UWP support in due course, also.

In my experience, it's fast at runtime, very easy to debug, very customisable UX, easy to code for in a pleasant, highly productive language with amazing tooling (best in VS, but Xamarin Studio on Mac or Linux isn't bad, especially compared to the competition), allows you to share often the vast majority of the codebase across platforms, has very good, but optional, Azure integrations should you want them - and free. Pretty compelling offering, I'd have thought!

xorxornop··on The Cost of Native Mobile App Development Is Too Damn High
Well, they (MS) have Xamarin, which is free, and targets Android, iOS, and WP. You could likely share a lot of the codebase with a UWP app also, since it's all .NET natively or supported (UWP supports other languages, eg. JS, C++ etc). It's a pretty compelling option, and works well in my experience.
xorxornop··on Facebook will lose 80% of users by 2017, say Princeton researchers (2014)
Because many users have no idea on how to find out what things are available and what's popular, and/or even that there might be aggregators of this info, or the concept of such.

Observe how many people do not even do a search for very simple things. The concept that they might be able to know or discover certain things doesn't seem to actually occur. Of course, this needs to be distinguished from their just being lazy, but even this is problematic, since it's almost always the case that finding it themselves is much faster than asking someone else (who will often essentially just do what the asker didn't...). It's almost a kind of learned helplessness, but with the "learned" part often being very short or implicit.

xorxornop··on LEDs may cause retinal toxicity at occupational domestic illuminance
Probably "overwhelming" pain. Where you almost complete loss of rationality, a torrent of sensation that blocks out all other thought and sensation - vision narrows to a point, sound becomes choppy and discordant, limbs feel far away or even absent (no, I don't mean the one that's potentially chopped off or something ;) , the other ones)
xorxornop··on SpaceX concludes anomaly investigation, sets return to flight target date
Cryogenic fuel is not the same is supercooled; supercooled is closer to freezing than to boiling
xorxornop··on Getting Past C
Hmm, I've had a very nice experience using Rusty Code in VS Code. Some useful refactoring functionality is missing for sure, but a lot of that will become possible quite shortly from RLS (Rust Language Server, a la how TypeScript works in VSC), and if your preferred editor has support for the language server spec (it's a open source common spec, not specific to Rust), it will support it at parity, too.
xorxornop··on U.S. Path on Legal Marijuana Forces Rethink in Mexico
Each of these statements are part of the truth; each are true but not the whole truth.
xorxornop··on Apple to slice iPhone production 10% due to sluggish sales
Yes. It has a high degree of control for that. I use many of these features; am running stock 7.1.1 Nougat on a 64GB Nexus 6P.
xorxornop··on Apple to slice iPhone production 10% due to sluggish sales
Uh, you could just sync the playlists (and the music, too, if you wanted) to Google Drive or Dropbox. Drive is the better option if you want integration.

Google Play Music (or any other music app) will then pick up the synced playlists

xorxornop··on Year of Upheaval for Restaurants That Ended Tipping
Because it perpetuates that culture. I'd really rather not perpetuate it.
xorxornop··on UK Government is breaking the law by collecting everyone's internet data
Correct, but in this case they haven't even figured out that they are being oppressed yet. Or that terrorism isn't then reason such policy was implemented,for that matter.
xorxornop··on UK Government is breaking the law by collecting everyone's internet data
Yes. Public perception and understanding of voting systems is consistently and distressingly abysmal. FPTP is an awful system that promotes ideologues and those that manufacture, manipulate and profit from them.
xorxornop··on Four years with Rust
That's all well and good if the context is unambiguous, but if it isn't, people will get used to having this done for them (or not even know that it happens at all), and then be totally perplexed. Worse, maybe then people want even ambiguous situations to be made friction-free, so the compiler must guess. Then you've got the possibility of very confusing behaviour, doubly so if the ambiguity involves any kind of polymorphism (different, possibly contradictory behaviour per type!)
xorxornop··on Four years with Rust
Yeah. Basically linting profiles. Reminds me of some proposals I've read about reducing the complexity of C++ without creating an actual subset or superset.
xorxornop··on Four years with Rust
The best use case I know of is avoiding the common Python & Ruby pitfall of "just stick everything in a dictionary and index it by key". Welp, forgot to update every instance of that string index (particularly if that name overlaps with anything else, including variable and function and class names... so, like, a lot of the time).
xorxornop··on Four years with Rust
More performant, generally, particularly considering the fine-grained control it offers. However, cyclic datastructures may be problematic (similar to how they are in typical GC, but often worse). Of course, exceptions abound; the "better" choice is extremely use-case dependent.
xorxornop··on Four years with Rust
Hmm, yeah cache thrashing sounds a likely culprit - agreed. Perhaps before dropping all the references they should be sorted by memory address, so that page faults are minimised.
xorxornop··on Four years with Rust
It's still runtime memory management. That makes it garbage collection in my book. Sure it's not as involved as tracing, the prototypical form of GC, but it's still something that requires a runtime check each time that resource is used or a binding to it goes out of scope, similar to aspects in generational GC.
xorxornop··on Orphaned by America's opioid epidemic
Yes, although I'd point out that a dependence on a low dose of Suboxone is really not that big of a deal; it being a partial agonist means that it doesn't really have adverse side effects over the long term unlike full agonists like traditional opioids or methadone. It may prevent relapse over the longer term much more effectively than abstinence.

I definitely agree with a point you raise however about the availability of lower doses - 2mg is far too high to jump off of, or even 0.25mg for that matter. Suboxone is commonly prescribed at FAR too high a dosage, 8 to 16mg or even 24mg, when in reality 4mg is plenty for almost everyone, and 2mg will work in many cases.

The withdrawal of Suboxone can at first glance seem not all that bad compared to traditional opioids, BUT - it lasts for at least a month, if not 2 or even 3. Suffering over a long time period is a LOT harder than people think. So, I think the pragmatic - and humane, for that matter - is simply to let the dependent person choose. Many may choose to discontinue it of their own volition if they are given the space to determine their own tapering plan and see how it goes. Forcing them into something is likely to cause far more harm than any perceived (to say nothing of actual) benefit.

xorxornop··on Solar Now Produces a Better Energy Return on Investment Than Oil
Well, how about the fact there's an absolutely enormous, untaxed negative externality? It's implicit - normally you tax something to reduce use of something harmful. Renewable energy would be far more competitive if this was factored in.

Fossil fuels are causing incredible economic damage - but in a way that isn't captured by traditional economic models. It's going to have huge costs to future generations - if we taxed it, not only would we get off fossil fuels faster, we might then have extra cash around to soften the blow when it inevitably comes.

Oh man, this is one of my new favourites
xorxornop··on How can mindless mathematical laws give rise to aims and intention?
Well, yeah. It's about AI because it's about cognition and the basis of self. Bit of a wider scope :p
xorxornop··on AMD Gives More Zen Details
What? No. They did Blender, Handbrake, Battlefield 1, and something else I don't remember. It met or exceeded the competing Intel chip in every one.

I know, I was surprised too... I used to buy AMD, but haven't in some time now. Perhaps I will again...

xorxornop··on Things You Notice When You Quit the News
In general conservatives seem to be more close-minded. It makes sense, really - they want to keep things the way they are. Liberalism on the other hand encourages introspection and change; informing oneself is a necessary part of that. So, those that distribute information are likely to be less conservative. You see the same trends in technology and science in general.

Note that this is not an absolute endorsement of liberalism; change can only be positive if people are properly informed, and doing it for the right reasons. And, well, they aren't - not for some time now. And it's been hijacked by identity politics (some is very good; some very bad, more to do with narcissism than anything else, sigh)

xorxornop··on SeaHash: Explained
Well, yeah, unless the input is smaller than the digest, hashing is effectively a very lossy compression!
