Maybe it's that I'm "into" embedded stuff and all that. Or maybe it's because I've been studying my Masters at a school with heavy emphasis on crypto. But this project rings my nerdy bells in so many ways I cannot really count anymore. It's way past cool.

The only thing that lets me down a bit is that there's so little following of the idea here at Slashdot. It's as great as it gets. Congratulations!

Comment Different needs (legitimate?) (Score 1) 109

I have a RF audio-only baby monitor. Our house is quite big, and during our twins' first ~three months, it was hard to hear them from a different room. After the fourth month (they are six months old now), we haven't bothered to connect the monitor again, as their lungs are strong enough for us to hear whatever happens.

And yes, we mainly used our monitor to quickly go check on them, to make the distress time as small as possible.

Now, continuously streaming a video feed of my babies over the Internet... What good would that be for? Maybe only for me to ensure a hypothetical nanny didn't abandon or mistreat them while I'm at work — But I'd have to be always on watch!

What kind of reaction could I as a parent have were I monitoring my kids away from home? What use would this really have for my kids' safety?

The IoT is coming, I know, and we will soon have intelligent flowerpots. The cats' litter box will tweet every time a cat goes to pee. Yay for tech!

But sometimes there's no need at all for more intelligence in our devices. I want a baby monitor to be reliable, easy to check and fix... And not dependent on issues that might break (i.e. my Internet uplink being down for some minutes). Sometimes dumber devices are more intelligent.

If you have been researching for years on the mating habits of the Papuan purple-eyed spider, finding the differences between their behaviour and that of other spider genii, you would surely include that description as part of your title — It would not be responsible to make others think the article is general when it deals with a very specific variety.

(please note that the example is entirely fictional and I know zero about spiders or biological taxonomy)

People are often satisfied with using "S3krit" as an encryption key. Explain why you need a key with decent entropy/randomness and so large there's no use in trying to remember it... Users will store the key in the same medium as the encrypted data. So much for crypto strength.

In most Latin American countries, the best universities are fully or partly State-run. Tuition is often free or symbolic up to Bachelors, and for posgraduate studies it is still *really* cheap by US standards — i.e. I'm studying a Masters degree in the second most important university in Mexico, and pay less than US$100 per semester. Of course, that's because I chose not to be a full-time student; as I would automaticallyreceive a grant of ~US$600 per month.

They complain about there being sharp stuff over there, then they put on tires that are made of kleenex which can't handle any sharp stuff. If I put tires like that on my car, I wouldn't be able to use the roads at all. Stop crying, get some real tires, and get the fuck over. We have to deal with all the same shit on the roads. We got better rubber.

Again, we (cyclists) must be responsible users of the public space. Those tires you mention are for competition, for speed bike, or if at all, for touring long-hauls — but not for city trips. For the city, we need good rubber tires, with enough texture to be able to stop effectively, and able to withstand minor puncturing objects. And if we don't, well, our bike is not fit for urban use.

I'd laugh at people using Monster Trucks to go to work (unless,of course, they work at a Monster Truck show :-P ), or people using Scandinavian winter tires in my (tropical) country. They are just not fit for it.

Cars and bicycles sharing the same space is madness. It makes no goddamned sense. Let's build cycle paths so that cyclists can have a place to ride.

They can share the space if they do so responsibly. Most city roads are not meant for high-speed driving. Most city roads will by themselves impose a ~40Km/h effective limit on cars — And bikes are not that much of a hassle then. Of course, motorways are off limits for cyclists.

But let's also expect cyclists to behave themselves when they're on the road. That's not how they behave in California. Most of them behave like total fuckheads

And yes, here we agree again. We can only coexist when both motorists and cyclists abide by the basic rules.

Fortunately car drivers are also trained to keep at least a meter distance when passing a cyclist. It seems that the problem in the US is that automobilists pass too closely and that because of that, cyclist claim the whole lane out of self-defense.

We claim the whole lane because we need to. If there is a hole in the pavement, I must be able to quickly move around it — Of course, I instintively do so to the right (with no chances of a car passing by too quick), but it's not always possible. But I can do it only because I ride near the center of the lane. If I were in the right side of the rightmost lane, I would not have any wiggle space. And, of course, that's where all of the (what's the name for the sewer openings?) are.

Don't know about your city, but in our driving law using the sidewalk is expressly forbidden unless you unmount your bike. And yes, I carry a copy of this law with me; it's not often useful, but I have taken it out a couple of times (when arguing with motorists, not with cops)

And it is somewhat true. I also have my tricks for my usual drive to work. If you bike to work, you will spend some weeks finding the best route and then optimizing it a bit — but after that, you will just basically repeat known patterns.

Cycling in places I am not familiar with means I must be even more careful, which translates to driving slower. And absolutely with no distractions (i.e. radio).

You will lose an important tape file.
