neohaven··on TMSU: a tool born out of frustration with the hierarchical nature of filesystems
It's multiple, interwoven hierarchies, which you can look at by "seeing" a particular DAG (a subset of the actual graph).

You can see this twin representation conceptually as Artist->Album->Song and also as Compilation->Artist->Song, the latter being a small folder with symlinks to the actual song directly.

It's really just two different trees.

neohaven··on Never trust the client
Even if you do, you still should never trust the client. Who knows when you might lose control of one end?
neohaven··on Namecheap live chat social engineering leads to loss of 2 VPS
"Here's a lock and here's what inside it, but you still can't break it because you lack a separate secret of no mechanical relevance" is the only way to make a system secure. If it is possible at all, you WANT a system where knowledge of all the mechanics do not allow people to crack the safe.

See encryption. A secure crypto mechanism is not vulnerable to disclosure of its mechanism. The key is the secret. The mechanism is not. Having a secret mechanism that relies on its own secrecy means your main weakness is someone explaining how it works to the outside world.

RSA is perfectly well-known. So is rot13. rot13 is crap, disclosure or not. RSA is not as crap, disclosure or not.

neohaven··on The sugar conspiracy: sugar—not fat—is the greatest danger to our health
It's a response to "a calorie is not a calorie".

Severe caloric deprivation is not the point of my statement.

neohaven··on The sugar conspiracy: sugar—not fat—is the greatest danger to our health
1) Actual pressed juice is fine. The matter gets confused when people don't realize that a glass of actual orange juice is 6+ oranges worth of juice. You wouldn't eat a dozen oranges without thinking about the caloric intake. But you'd drink a few glasses of OJ because it's not as filling.

2) Thermodynamics... That said, a thousand calories of soda is half a day's worth of energy in sugar form. Your body uses sugar first when available, as a general rule of thumb. If you ate any fat that day, it will use the sugar, store the fat. More efficient than turning the sugar to fat, which we are bad at. (Humans aren't great at ketogenesis.)

3) Your body also understands sugar just as well. Blood glucose is an important bodily stat for good reason. Your body also uses protein and various trace elements in your diet, and it "understands" and "uses" all of them. Sugar is just more convenient to use than fat, so it uses that first and stores the fat. On ketosis, you just end up taking some of the stored (or dietary fat) and turning it to glucose in a hugely complicated process (think of it as "inefficiency in storage/packing/unpacking" the sugars into fats and back) and then using that to feed the ATP cycle to run the furnace. You don't run on fat. You store glucose as fat because high levels of glucose in the blood are bad. And then you store the fat outside the blood because that too, is poisonous in high amounts (see ketoacidosis). Your body is a fine-tuned machine that runs on pure glucose and happens to have a set of machinery that makes all animal/plant inputs (fats, sugars, protein, minerals, vitamins) into either A) machinery bits for maintenance or B) more glucose to burn.

4) Sugar (whether it is glucose, fructose, sucrose, lactose, maltose, w/e) is a functional way for a lot of things in nature to feed themselves, including us. Whether it is honey, the inside of an apple, or a grapevine, lots of things are full of easily digested sugars. Sugar, as much as you'd like to claim is "not necessary", is everywhere in nature, as it is a part of most living things.

5) Salt is bad, indeed. As a general notion, equilibrium should be attained in the body fairly easily. The bigger problem people don't think about is the K/Na ratio and such. As a general rule, salt is overused in our food. That one I agree with. No idea why you tacked on anything about sugar here.

6) Energy in, energy out. You're just a fancy (REALLY fancy) way of burning food slowly (given that you exhale some carbon in your food through CO2... and you used the O2 you breathed in to combust that food.) You happen to do useful work with the fact that you can invest a small amount of energy to gain a lot of it. It's a side effect. Locomotion and keeping the food-burning oven running and clean are the main reasons you use calories. The problem with the OJ glass at breakfast is detailed in 1) and has nothing to do with sugar and everything to do with the fact there's little finer and little satiation to orange juice so you drink far more calories than you'd ever eat from the actual fruit.

We prepare foods for easy consumption, but a lot of food is made to be filling as a way to self-restrict. Our more basal impulses ("eat until you're full because there may not be more food for a while") are woefully maladapted to our world.

neohaven··on iPhones 'disabled' if Apple detects third-party repairs
THE critical security system of your phone has been tampered with. PIN data, TouchID data, crypto data and everything else related to security is on that same bus. You do not detail secure info over that channel.
neohaven··on iPhones 'disabled' if Apple detects third-party repairs
On TouchID phones, the PIN is held in the same secure enclave as the TouchID data.
neohaven··on Monsanto Weedkiller Is ‘Probably Carcinogenic,’ WHO Says
Water, drank too much, too fast, can kill you.

The dose makes the poison.

neohaven··on Why Your Netflix Traffic Is Slow and Why the FCC Won’t Necessarily Make It Fast
> That's terrible. The ISP should give me "internet access" which includes everything out there. They should not get to pick and chose what I can get.

That is not what last mile means.

neohaven··on After Jobs Dry Up, What Then?
Yep. When you can't hold up the "you can't find a job because you're lazy/a slob/stupid/etc." narrative, we'll get these things.
neohaven··on Why Does the International Space Station Have That Shape?
You'd need to bring the metal up before anyway, in that case. It doesn't really solve the major problem.

It would be easier to build them on earth still.

neohaven··on Macbook screen coating issues
Just a mention : e-cig refill fluid is mostly propylene glycol and glycerol. It's not an oil. It's a sugar alcohol. :)
neohaven··on Windows Hello – Biometric authentication to Windows 10 devices
Biometrics is identification, not authentication.

It identifies who you are talking to, which is not the same as confirming who you are talking to (verifying authenticity of identity.)

neohaven··on Dropbox Is Probably Not Stealing Your Files
Actually, it cannot for the shell extension for the checkboxes over synced files. It needs to look at every file seen with Explorer to do that.
neohaven··on The curious case of disappearing Polish S
It means "Save the thing I'm looking at".

Ctrl-S says to your browser "I want to save this".

neohaven··on HTML5 Video and the End of Plugins
Sadly, good, solid DRM (Here's an encryption key, an encrypted file, and a secure way for me to limit when and how you can use those) is the ultimate form of Snapchat.

If you don't have DRM backing it up, the scenario is "Here's a key, a locked box, do whatever you want with the decrypted file." Which is less secure than being able to actually limit usage of the decrypted file.

Nothing here implies that I think DRM is a good thing, mind you. I just think saying something is "just DRM", as if DRM wasn't basically encryption + limitations on use.

neohaven··on Do Small-RAM Devices Have a Future? (2011)
Can you? Sure.

Should you? Oh, sure, if you want a very expensive piece of hardware in your product.

neohaven··on Bastion hosts
I shouldn't have to grab a page curl to see a website. A disclaimer of "Hey we notice $X is your browser, maybe switch to those?" with a "No thanks, I'll deal with it" option on some modal JS dialog.

Direct quote from the page at the other end of this link :

"You appear to be using a browser that may not be able to display our site correctly. Generally, this is beause it's an older browser that doesn't support a lot of the newer, awesome features in open Web standards.

Rather than provide an untested and possibly subpar experience of our site, may we suggest downloading one of these fine browsers? (We think you'll find your overall experience of the Web will improve if you do.)"

This is followed with links for Firefox and Chrome. I am running Firefox 24.4 from CentOS repos. This is unskippable, and there's no simple way to bypass it on the page. On a browser from March of this year.

Urgh.

neohaven··on Homer's Last Theorem
Fermat's Last Theorem is proven true, is it not?

Without having seen the proof that came to Fermat's mind, I don't think it's anyone's absolute opinion on the matter that "It's not up for debate" and that Fermat's proof being potentially true is "missing the fundamentals of science".

If you may re-read my previous post, here's the thing people disagree on : "Did Fermat write this having a correct proof of it on his mind or not?" I do not think anyone can say an absolute "yes" or "no" to this. Although it does point to "no", considering that the mathematics used to prove FLT are far beyond Fermat's time.

neohaven··on How Caffeine Can Cramp Creativity (2013)
This "chemical composition" is like reading packets off a broadcast network. It's not the full state, but it's good enough to reverse-engineer what's going on at a high level.

Blood work, including blood neurotransmitters and hormones, can tell you a lot about someone's state of mind specifically because of this.

neohaven··on Homer's Last Theorem
1. You mean "David Samuel(S.) Cohen", one of the writers for The Simpsons and Futurama, who decided to make his name "David X. Cohen" (not his legal name) because the Writer's Guild does not accept duplicate names?

2. Yes, people do believe he had a proof somewhere in his mind, considering the rest of his track record. Whether that proof was correct is definitely up for debate.

neohaven··on I'm Leaving Mojang
He had money before the deal. Notch is solidly a billionaire.
neohaven··on Steve Jobs Introduces the iPhone 6 and Apple Watch
Not necessarily.

There could also be a "Well if Apple is going to release something right after the holidays, the other companies might try to make better models right after the apple watch comes out" feeling. Sort of the feeling that Apple might get one-upped by Samsung, et al.

neohaven··on Ignore No More – lock your child's device until they call you back
No, by playing a game.
neohaven··on Countries don't own their Internet domains, ICANN says
The TLDs are not property, they are assigned by virtue of a physical space, like a postal code or an address.

Domains are property, are bought by virtue of wanting a specific name, and can be sold.

neohaven··on Healthkit
I would be more inclined to use a product that interacts with it cleanly for specifically that reason. It just means that the quality of the hardware and software needs to be the differentiator, instead of it just being "Whoops, you're stuck in this silo now."

It just seems better to me, even for the market itself.

neohaven··on My No-Soap, No-Shampoo, Bacteria-Rich Hygiene Experiment
Soap, by virtue of being soap, has antibacterial properties because it disrupts fat layers by making them dissolvable in water, iirc.
neohaven··on The future of Unreal Tournament begins today
I love the movement mechanics of previous UT games, between always-run, dodging (doubletap a direction), double-jumping, and walljumping (jumptowards a wall, doubletap opposite direction), it was a rather entertaining game to play. Add to that the completely crazy weapons by today's FPS standards, and you have something I haven't seen in a long while.

I wish it would come back.

If it has that, that game has a player.
