  1. Why should I care? on German Police Warn Parents To Stop Posting Photos of Kids On Facebook (thestack.com) · · Score: 5, Informative

    I say this as the father of two little girls. But if I post pictures on facebook of my daughters they are photos that I have deemed OK for public consumption. They are photos that if they were published on the front page of a news paper I would be absolutely fine about it. So given that, why should I care if someone with a perversion finds one of them titillating? Yeah it's definitely pretty high on the gross out scale but maybe I shouldn't post pictures of my cat then for a similar reason?

    This is a totally totally stupid suggestion. If someone does collect photos of kids off the internet from facebook NO CHILD IS HARMED. Stupid.

  2. Re:Gun Control... on US Toddlers Involved In Shootings On a Weekly Basis (washingtonpost.com) · · Score: 0

    No there is a third argument. And that is gun control. Make it mandatory for guns to be kept in a safe, unloaded with the ammo kept in a separate place. Make it mandatory that all firearm owners attend a number of supervised shooting events per year. Get rid of public carry. Make it much harder to buy a gun and get a license, add cooling periods for purchase, add limits to how many weapons 1 person can own, give license classes that impose different restrictions based on weapon type (automatic, semi-auto, concealable, antique, shotgun etc) so the most difficult license to get with the biggest checks and restrictions will be concealed handguns, then full auto rifles down the the easiest, your blank power replica cannon. Make all gun ownership transfers go through a registered gun broker.

    People will argue against this saying it will only effect legal owners, and to begin with this is true. But over time it will reduce the illegal supply of guns as people are unable to dispose of their guns for cash. This will increase the black market price, which will directly reduce the numbers in crim hands.

    The last part is to have a registration and buy-back period. Register your weapons & get a license, if you dont want to get a license put your gun in this pile and I will pay you their market value, no questions asked.

    Nothing here stops you owning your guns. But it makes them more secure, harder to steal, and harder for them to move from the legitimate to illegal market.

    The Irukanji jellyfish is an extremely fucking nasty box jellyfish which is predominately found off the north coast of Australia. Originally it was thought to be localised to that area but they now know they are far more distributed. This jelly fish is the one that has been found off the coast of Japan, India, and Florida. But the thing is they are tiny, about 1cm3 so unless you are getting instances of the syndrome they are really hard to detect.

    There is nothing about changing currents or biomes that can be tied to the location of those creatures. They are just really really small so unless you are looking for them you won't see them. I mean it took researchers 12 years to find the damn things in the first place when the syndrome was originally identified and they knew where to look.

    I think if I can get the motion sensor location to sit just in front of the swing arm pivot point it will solve a huge amount of the data problems. I'm not convinced I can achieve it from where the box is under the seat. The results for heavy acceleration look an awful lot like "you hit a big bump" or the rider stood up on the pegs currently.

    My bike is a CBR1000RR so it has a high acceleration factor but it also means that on the road you don't get to use it that much or for that long....legally anyway. So the high acceleration is often short and sharp.

    My goal was to model the rotation of the bike around the X & Y axis as well as cornering forces, braking and acceleration.

    This is what I am recording atm:

    Absolute Orientation (Euler Vector, 100Hz) Three axis orientation data based on a 360 sphere
    Absolute Orientation (Quaterion, 100Hz) Four point quaternion output for more accurate data manipulation
    Angular Velocity Vector (100Hz) Three axis of 'rotation speed' in rad/s
    Acceleration Vector (100Hz) Three axis of acceleration (gravity + linear motion) in m/s^2
    Magnetic Field Strength Vector (20Hz) Three axis of magnetic field sensing in micro Tesla (uT)
    Linear Acceleration Vector (100Hz) Three axis of linear acceleration data (acceleration minus gravity) in m/s^2
    Gravity Vector (100Hz) Three axis of gravitational acceleration (minus any movement) in m/s^2
    GPS tracking 10Hz

    The summary is backed by a number of other studies which controlled for background, education, crime type, region, gender, race and also covered those people that were court mandated to courses as well as those that chose to do courses. The full report is linked off the bottom of the summary page. I would suggest that you can have a high confidence that the schemes have a positive effect of reoffend rates.

    The results had already corrected for the following:
    The analysis found that prisoners who are less likely to be studying:
    v are males
    v are Australian-born
    v attended government secondary schooling and/or
    v have prior prison sentences.

    Those prisoners more likely to be studying have:
    v children
    v education above Year 10
    v worked in the five years prior to the current prison term
    v already completed a trade qualification and/or completed another
    educational qualification.

    their release dates come closer.

    Left to right lean looks normal. But under acceleration it manages to look like the bike sinks into the ground because the motion the sensor goes through is almost solely in the vertical plane. And then under brakes the sensor says my bike gets about 240mm off the ground which is kinda funny.

    It is causing me a conundrum though as currently the whole thing is sealed and self contained at about the size of a pack of cards. There isn't the space to fit that to the bike anywhere near the centre of gravity though so I will have to break it apart to get it into the right place.... Not sure I want to do that though.

    That said the next step is to have sensors on the suspension and the brakes but I'm not sure how to do that yet.

  9. Re:Give me a raise on 'First, Let's Get Rid of All the Bosses' -- the Zappos Management Experiment · · Score: 1

    It's because the system you describe simply doesn't work / exist. In your example of the medical practice the office manager would never manage the doctors. The person managing the doctors is the owner / partners of the practice. They are the ones that say "Hey Dr Billy Bob, I know you hate doing it but you are on to do the skin check clinic Tuesday afternoons." Or the ones to say "Dr Muppet Head, I've reviewed your patient records and prescription records and you are prescribing too much of X when I'm not convinced it is required. As such I will be reviewing your patients when you want to prescribe this drug".

    The office manager is there to make sure that meeting rooms aren't double booked, keep supplies right, intercept the medical drug marketeers etc.

    Then in an Engineering practice you start as a grad, become a full engineer, become a team leader, become a principal and then some will become functional managers. Each has a different role to do. A junior engineer cannot sign off on drawings, or manage a project for delivery, or have the experience to interface with the clients, or have the knowledge to even know how to start a project. So they have a team lead to manage them. Then the team leaders they tend to be delivery focussed. They have come from a delivery background but now their role requires them to business develop clients as well. Their role has expanded to keeping their team busy as well. So the functional managers are there to help them, train them and guide them in the winning of work. Engineering is not a sector where a person with no engineering background can be an effective sales person because the clients tend to be engineers themselves.

    And finally your functional manager has the job of overseeing the much larger project business development, the resourcing requirement of hiring and firing, of interfacing your highway team with the infrastructure structures team with the geotech team with the water team and the electrical team etc.

    Managers usually have come from a background that matches the sectors they are managing. This holds until you are senior enough that what you are managing is managers so your specific technical background becomes less important and you move towards the business components as your core skills.

    Yeah temp sensor doesn't need to be that fast. But I couldn't be bothered specifying different times for different sensors. Sorry was being lazy.

    I've built a custom telemetry system for my motorcycle and it is running at 10Hz for all the sensors. It is total overkill for some of them but I have used that number because it is the sampling frequency of my GPS receiver and it dead simple to work with the raw data later. That said I'm not sampling temps, its all motion stuff. It's pretty cool because I can animate a 3d model of my bike going through the same ranges of motion that my bike went through on a particular ride.

    If you have physical access to the car I would be very worried if you couldn't compromise the system. But lets see if you can compromise it without taking off a panel, disconnecting a wire, or otherwise having privileged access to it. This claim is no different to any myriad mechanical exploits that could be put onto a car if you had physical access.

    As for "infotainment" systems you can't have a bad system without a good/better one to compare it to. If you have a brilliant system it will make your competitors look worse and will absolutely be involved in the purchasing decision. The manufacturer of my current car wants $600 to update the maps in the in system GPS. It also doesn't support A2B despite it having a full handsfree system built in. When we come to replace that car I can absolutely promise you the in-car system will be high on the list of deciding factors.

    Exactly. I've built a telemetry recorder which I can put under the seat of my motorbike. It records GPS, acceleration, magnetic direction, angle of lean, and physical angle of the bike. Currently it is self contained and doesn't have any direct sensors on the bike but that is next. I also need to move its position as under the seat is too far from the centre.

    When I get home I sync it with a gopro recording and a rendered 3d model of my bike.

    But all of this needs to be manual. The box has a battery and is self contained and it is a hack to access it realtime (wifi hotspot and webserver).
