"Mom, why do I always have to wear a helmet outside?"
"Shut up and bring more of those dead drones to the recycler than last month!"
The drones are built with the same components used for model helicopters.
The batteries last only minutes and every additional weight (including stronger batteries) costs more energy. Taking energy inductively from power lines can work, but at the cost of turning the power lines into drone highways. This may cause traffic jams and collisions. Also, the batteries had to be reduced to a minimum to allow a greater payload and the additional induction coil and battery charger. The drone could only reach places that are less than a few minute's flight time away from a power line.
The motors are not built for constant use. They produce too much heat which lowers their life time. Allowing the motor to cool down between flights prolongs their life, but even then they would only last some days of constant use. Failure would be hard to predict. Just last week a friend#s new motor failed after less than an hour of total flight time. Motor failure in the air leads to a nice destructive crash. A traditional helicopter at least allows a skilled pilot to land with auto rotation. The extra weight for heat sinks or more robust motors again would limit the usefulness of the drone too much.
Lithium polymere batteries tend to degrade quickly when they are discharged too low. In that case not only their capacity is quickly reduced. They can also heat up too much and catch fire or even explode. The batteries can be monitored, but what should a drone do when the battery fails and begins to heat up? Land? Ask for help?
Ah yes, another great cause of failure is vibration. Vibration can weaken carbon fiber structures or cut wires. No matter what breaks of fails that way, the result usually is a crash. And again, the extra weight for reinforcing everything as a precaution gets expensive.
What use would be drones that need that much maintainance or most probably crash within a few days of autonomous operation?

Have you guys noticed the ::Workspaces counter on the main page?
A few days ago it was below 100,000 (I want to say it was at 90,000 last week, but I could be wrong). It looks like this feature is really taking off. I want to get started on a ::Workspace project too, but I just don't have the time right now.

Do not forget that every article opens a workspace, automatically...but it's really nice - I moved my projects from TFS online and like it very much...

Right, but I really don't think +20,000 new articles were created in the past week.

I just found out that when you download a file from an article, you get a new ::Workspace created, forked from that downloaded file. I can see how that can add up in a hurry.

Are you sure!? I have an article with over 200 downloads in the last 3 weeks, but I can't see even one fork...or maybe all that members have no ::Workspace?
You right - just checked it...

This must be a very new feature. I download files attached to articles in the moderation queue to check if everything is alright and I had not seen the ::workspace forking until today.

Perhaps you should[^]? The government here is suggesting I do it anyway.

Perhaps I read it wrong, but the vulnerability allows someone to get the encryption keys that are used so at that point it won't matter how often you change your password, they can decrypt the traffic directly.
There are only 10 types of people in the world, those who understand binary and those who don't.

Seems like it was a server side[^] issue that could be problematic. And here[^] as well.
I think its just a problem if you have the same password everywhere.

Yes, only change your password after the service have patched OpenSSL and reissued their SSL cert.

Griffs post[^] below suggesting that we should put a stake in the steering wheel is actually not a new suggestion.
John Adams, risk expert and emeritus professor of geography at University College London suggested that[^] a few years ago.
What's that to do with kids? Lots it seems like. Kids behave the same way, despite that our playgrounds are seemingly "safer" nowadays it's not reflected in statistics.
So, what's the solution then? Reasonably safe playgrounds where the kids are allowed to explore their limits themselves seems to be the answer.
Here's[^] an article about a playground that's quite a bit like how our parents grew up, but now it's experimental.
Oh, the article is quite long for the twitter damaged people but worth it IMHO.

Perhaps football/soccer should be played like this[^] just to be on the safe side.

Excellent article about the Land! I feel sorry for these pampered little pansies being raised today. Not their fault, of course, but they won't be good for much when they grow up.

Similar article in the NYTimes last year[^]. My kids are growing up falling down. They're getting bumps and bruises and scrapes and I bashed one of them in the head with my camera the other day. An accident but now she knows not to try and head-butt daddy's "combat" trousers, they have a camera in them.
And we found an old-school playground awhile back. Has one of those deadly jungle-gyms in it. Kids love it.

Good tip, I have to find my old camera, my two year old daughter has started head-butting me in the "jewels". She has the fun of her life when I cringe in agony.

Two weeks ago a first grader at a school in my town climbed eight meters (26 ft) up in a tree, needing help from the fire department to get down: http://www.adressa.no/nyheter/trondheim/article9397159.ece[^]
I was so happy to read the school headmaster declare that they will NOT forbid tree climbing in the future.

Part of the daily routine (in between lounge sessions and coffee) has been looking in on my ftp server log files. It only takes a passing glance to see that the server has been attacked. I have seen dictionary attacks and brute force attacks on the Administrator account. This last episode which lasted for over almost two hours was the latter variety which always follows this pattern:
Administrator - 1243 attempts
Administrateur - 1243 attempts
Administrador - 1242 attempts
Administratore - 1244 attempts
The server is running Server 2008 and of course IIS 7.5. IIS 8.0 offers a dynamic blocking feature for FTP, but that really is the only compelling reason I have to upgrade to Server 2012. I have searched high and low for a free utility for dynamic blacklisting for the FTP service. I even found source code for a utility that worked with Server 2003 but found that it was not compatible with 2K8.  On to plan B...get a list of all the IP address for a couple of countries and build a utility to import them into IIS. Plan B was a huge success, eliminating most of the attacks. Now, the ones that still get through are more an annoyance than anything. If it was still a major problem, I'd probably look into hosting the FTP service on nix, for which there is an open source lockdown utility available.
Anyway, the point of posting this was that I was thinking that it might be fun to create a sort of Pandora's Box by creating a fake Administrator account with the password of something like 'password'. The ftp account's home folder could contain some fun content. Question: What useful content might you leave for a theif hacker?
