Comment Re:Meanwhile, here in Europe ... (Score 1) 250

Where in Europe? The open market does not mean that everything is priced the same everywhere. At least in the Netherlands, I don't think you can get 70 Mbit/s for 16 EUR/mo. The lowest tier is about 20 EUR for 10 Mbps ADSL including phone or 30 Mbps without.

I did once (July) install an app with that name, but there are many with the same name on the Play store. I uninstalled it the next day because it was crap. Screenshots look familiar, but I'm not sure.

At least I don't see any suspicious files with setuid permissions, but then: /system/xbin/su is also mode rwx. I guess I'll reflash my ROM (CM13) this weekend, just to be sure...

"the usual human reaction to the smell of Cadaverine (pentamethylenediamine) and Putrescine (tetramethylenediamine),"

Quoting the wiki:

"Basic amines such as putrescine, spermine, spermidine and cadaverine are responsible for the smell and flavor of semen."

What human reaction, you said?

The chances of anyone in particular having a doppleganger may or may not be one in 137, depending on how you define it, but the chance of there being dopplegangers is about 100%.

To oversimplify a bit, there could be millions of them in fact, because there's billions of people, and EACH of them have a 1 in 137 chance of having a doppleganger.



So it doesn't sound like their software is very good.

Comment Re:Do bats really control mosquitoes? (Score 3, Interesting) 115

"not only do bats (and purple martins) not eat that many mosquitoes, they also eat other insects that would themselves eat mosquitoes, such as dragonflies."

Dragonflies hunt by sight, during daytime. Bats and mosquitoes are active at dusk and night, so this doesn't sound very likely as far as bats are concerned.

The use of hygroscopic products to speed up drying is actually based on a misconception, or at least, not as effective as you might think.

The rate of evaporation is proportional to the product D*(p_vp-p_env), where D is the diffusion coefficient of the vapor molecules in air, p_vp the vapor pressure (partial pressure of saturated vapor), and p_env the partial pressure of vapor in the environment.

A desiccant will lower p_env to zero, so it will help a bit; for example, the p difference is (2.4-1.2) kPa at 20 C, 50% relative humidity, increasing to (2.4-0) with a desiccant, a factor 2 increase. However, putting it in a warm place will increase both D (a bit) and p_vp (a lot). Heating it to 50 C in the same environment will increase the p difference to (12.3-1.2), a factor 9 increase. Additionally, D will increase by a factor 1.2. A phone that is switched off should be able to handle such temperatures, so putting it on top of the cable modem is cheaper and more effective.

Even better would be to dry it in vacuum; that will increase the D parameter tremendously. But most people don't have that at home, although I suppose that some creativity with a wine preserver pump might get you somewhere.

"CyanogenMod (...) uses the "old fashioned way". No TrustZone, no fancy footwork with keys... just a relatively simple prompt for the passphrase at the phone startup so /data can be mounted and used."

I'm using CM13 (Android 6/Marshmallow), which uses FDE, yet can boot without password prompt, just like stock Android 6. It will present the lock screen though. Leaving aside the security of a booted and connected phone with only the lock screen as a protection, the only way to do this seems to be to use some kind of trusted execution environment. Otherwise, you could pull the entire encrypted data partition over USB from the (obviously non-stock) boot loader and have all the necessary data to decrypt it offline.

Comment Re:Still call the 440Hz "A" note? (Score 1) 171

"military and brass music uses 461 Hz. https://en.wikipedia.org/wiki/... "

The number 461 does not occur anywhere on that wikipedia page and it's the first time I hear it. I used to play the trumpet. That was before you had digital tuners but I don't recall that there was any problem to get it in tune with a standard piano. The closest statement is:

""high pitch" was used for the older tuning of A = 452.4 Hz at 60 ÂF. Although ... low pitch, provincial [english] orchestras continued using the high pitch until at least the 1920s, and most brass bands were still using the high pitch in the mid-1960s."
