Comment Start a hot dog fire with booster cables (Score 1) 210

My brother and his friend found themselves without any matches recently, but needing to start a fire to roast hot dogs and marsh mellows over. Using a paperclip and jumper cables they got the fire going quite quickly so they didn't have to eat raw hot dogs. They did have to carefully lay the fire though with lots of tinder as the paperclip only lasted a few seconds. But it was enough.

A pair of ubiquiti NanoStationMs work well enough you may never have needed to implement the cable, though the NanoStationM is limited to 100 Mbit/s. I use it to get a solid network connection between two houses 400 feet apart and it works great. I actually get the full 100 Mbit/s out of it which is pretty impressive. The low-end units can work up to a kilometer away. I had been planning to trench in fiber optic, but this works so well for me that I've abandoned the idea of running the fiber for now. At least until I really need Gigabit across the link (or more).

People from the USA are always amazed when they hear anybody would try to enforce the spirit of the law, not the letter.

Laws should mean what they say. If they mean something other than what they say, they should be repealed or rewritten. If the police can arrest you, not because of what the law is, but what that cop thinks the laws should be (the spirit), then you are living in a police state.

Comment Re:Idiocy. Anyone have facebook photos? (Score 1) 77

I doubt that. I doubt that a facial recognition software can differentiate reliably humans and photos (or videos)

Try this:
1. Show your mom of photo of yourself.
2. See if she can distinguish between you and the photo.
3. Ask her how she did it.
What she will say, is that the photo is 2D and you are 3D. As your mom shifts her head left and right, she sees you from a slightly different perspective.

A cell phone can do the same. It has a 3-Axis motion detector, so it can detect its own movement, and see if the perspective of your head corresponds to that movement. It would be impossible to duplicate that with a photo, and nearly impossible to do it with a video.

a person could be standing still and then you get a false negative

No human with a beating heart can hold a phone that steady.

Personally, I find a chip + PIN save enough.

That option will be available if you prefer it.

Maybe they should extend the PIN to 5 or 6 digits.

Bad idea, since people will write them down. 4 digits is good enough. Brute force guessing of PINs is a non-problem.

Sure but SpaceX's goal to land the first stage has little to do with its cargo launch capabilities and its recent launch failure, or its march to man-rated rockets and the heavy lift booster. So I argue SpaceX is still doing very well in this lap. They can lift about one metric tonne more than the Progress freighter, and they are the only ones with return cargo capabilities. Return capabilities we haven't had since the Space Shuttle. I'm glad to see the Japanese cargo vehicle getting good use, and I'm happy to see all the different companies enter this space (literally). SpaceX happens to be the American company the closest to providing independence for western astronauts.

It is still stupid, as the software can be cracked

Yup. It is based on public key cryptography, so all you need is every quark in the universe calculating once per planck time, and you will have it cracked in less than a googol years. Trivial.

you could cheat the sensor with a photo printout or a photo on another phone.

Can you look at a phone and tell it isn't a live person? Why do you think it would be difficult for a computer? Some early naive implementations of facial recognition could be fooled by a photo. Modern state-of-the-art facial recognition can detect the difference.

This technique may not be perfect, but it is a big security improvement over the current system. It will require two factors: biometric and physical possession of a registered device. For transactions over a set size, it could require a PIN as well, as a third factor.

Comment Google apps getting slower and more bloated (Score 3, Insightful) 110

Lately, every time I've allowed a google app to update I've regretted it. I was just fine with gmail the way it was. The latest incarnation I just don't like. For one I really hate how they are starting to ignore the menu button on phones that have them. I like having a menu button down at the bottom of the phone, close to where my thumbs are naturally. If I wanted an iphone I would have bought an iphone.

In any case I've learned to never update a google app that I like. One of the biggest problems with the Google Play walled garden is the complete lack of version history. Once a new version is out, the old version is gone forever. Always backup your apps before upgrading I've learned (and forgotten too many times).

But the real problem is that google apps are getting bigger and bigger and slower and slower. I don't install very many apps, and I finally ran out of space on my older phone, due to mostly google apps getting so huge. And over time my phone is getting less and less responsive. It's not like I have a lot of apps installed, and I never automatically update them. I do it judiciously, after looking at the changes list.

As I mentioned I don't update google apps much anymore, but the Google Play app and infrastructure update automatically and silently, and I have a hunch this is part of the slowdown. Sometimes I get a ton of "google play services has stopped" error messages until I reboot.

That isn't the issue. The issue is YOU being able to share MY WiFi key because I was dumb enough to let a Windows 10 user on my WiFi network. This is akin to me giving you the keys to my house so you can housesit, and you getting a hundred copies cut and distributing them to a bunch of people you know.

So wrong.

If you *tell* someone your WiFi password *then* there's nothing stopping them from sharing it with whomever they want. So do not do that. Not if he brings OS X or Linux or Windows.

If you want to allow some friend onto your network but not allow him to share your network with others, then *you* tap in the password at his computer when it connects. On OS X or Linux or Windows. That what you would do today, and that's what you would do when your friends brings a Windows 10. On Windows 10 simply DO NOT CHECK the "share" checkbox. It is off by default. Your network will not be shared.

Nothing has changed. Neither your network nor your password will be shared with anyone. Your friend cannot go into settings and share the network after the fact - it has to be done when connecting.

But if *you* connect to some network which you would like to share with your friends, you can check the "share" checkbox. When you do that, your password will be stored encrypted in Microsofts servers. When one of your friends (if you share with - say - Facebook friends) is in range of that network, his Windows 10 computer can engage the network. The network will issue a challenge with must be hashed using the password as salt, and the hash returned. Modern password auth works like that to avoid sending passwords in cleartext. This means that the *actual* password hash is a one-time hash computed from the challenge.

The computation of the hash is performed on Microsofts servers, and your actual password is NEVER available on your friends computer - not even in encrypted form - only the challenge response hash. Your friends computer must obtain the response to the challenge from Microsofts servers - and when doing so it must prove that it belongs to a friend of yours.

Furthermore, Windows 10 which connects to a network in this way will *not* allow access to other devices on the network except for the internet gateway. I.e. it can only be used for Internet access - nor for local file or media sharing.

TV has been a bad mommy's best friend for a long, long time. In the 80s we used to keep "TV logs" at school to show how much time we were watching and to try to encourage less viewing. There was even that infuriating period with "educational" VHS/DVDs for infants.
