  1. Thank you! on How Close Are We To Engineering the Climate? · · Score: 1

    Isn't global warming [from greenhouse gases] an exponential system?

    The opposite, it's a logarithmic system. Every ounce of CO2 released produces less warming than the previous ounce. This is why climate scientists talk about warming in terms of "a doubling of CO2", because if it causes 1 degree of warming with one doubling, the next doubling will also cause a degree of warming.

    Great response!

  2. Summary video on How Close Are We To Engineering the Climate? · · Score: 4, Interesting

    The panel posted a quick summary of their results and findings.

    Isn't global warming [from greenhouse gases] an exponential system? When the planet gets warmer, doesn't that release more greenhouse gases from clathrates under the ocean, causing more warming?

    Isn't offsetting an exponential response by using another exponential curve difficult? I thought that was what made nuclear reactor regulation difficult.

    Any control theorists in the audience who can shed light on this?

  4. Duty to intelligence on Publications Divided On Self-Censorship After Terrorist Attack · · Score: 4, Insightful

    How about a duty to intelligence?

    Look to the future and consider two outcomes: where media self-censors based on threats of attack from extremists, or where media blatantly continues in the face of such threats.

    The decisions made today will bring about one of these scenarios. It's a simple case of "payback horizon": how far ahead do you plan for.

    If you self-censor right now, it will protect your people and your business near-term, but over time you will find yourself increasingly subject to threats and attacks, you will be self-censoring more and more.

    One of the definitions of intelligence is the ability to put off short-term rewards for a larger long-term gain. Being frightened into submission has near-term benefits, but those policies will not end well.

    You made that all up.

    I observed, noticed a trend, and came to a conclusion. You should try it some time.

    Minor exceptions don't make a rule less useful. Check out Newton's Laws sometime.

    A rule is useful to the degree that it conveys [read: compresses] information. We teach that the world is round because as a rule that statement is pretty accurate, and only later do we admit that it's an oblate spheroid or use other, more accurate representations.

    I can't say "leaves are green" without some idiot on the internet pointing out that Poinsettia leaves are red.

    So I have to say "tree leaves are green" until some idiot on the internet points out that Chinese maple tree leaves are red.

    So I have to say "most tree leaves are green" at which point some idiot on the internet points out that tree leaves change color in the fall.

    So I have to say "most tree leaves are green most of the time..." and the statement is mushy and filled with weasel words.

    Newton's laws compress the almanac of cannon ball weights, forces, angles, and the subsequent arc of travel into a half page of information. That's pretty good compression for a rule, even though there are exceptions.

    That's not electronics either. Electronics is about physics, you'd like to play with a vacuum tube to actually see a hot cathode and measure currents.

    Electricity is moving power from place to place (using electrons, to distinguish it from steam engines, plumbing &c).

    Electronics is adding power to signal (again, using electrons to distinguish it from other forms such as hydraulics and pneumatcs).

    Calculating the maximum load on your 15 amp circuit is electricity. Most of the wiring in your house is electricity, because it's concerned with moving power from place to place.

    Amplifying an audio signal to put through a speaker is electronics. Amplifying a sensor to be read by a micro is electronics. You're adding power to the signal for various purposes.

  9. Here's the insight on Nest Will Now Work With Your Door Locks, Light Bulbs and More · · Score: 4, Insightful

    It never ceases to amaze me how "stop liking what I don't like" posts get moderated to +5 Insightful.

    Where is the insight here? Other than the clear insight into the poster's fear of experimental, new technologies and applications.

    The insight is that this is a subscription model without subscription value. It's an MBA thing, and comes from studying the model without the context in which it is successful.

    Companies see the subscription model as a cash revenue source, and there are several successful examples currently working: NetFlix, iTunes, internet service, phone service, and so on. Get your customers to sign up and sit back and watch the money roll in.

    The problem is when the subscription model doesn't give ongoing service. Fitness monitors comes to mind - you purchase the unit to measure your daily activity level, but you *have* to use their online service to see your results. You can't [easily] download the data to your local computer, and the interface is obscured or encrypted to prevent the user from intercepting it.

    There's no reason for the online subscription, except that it makes money for the company. People eventually realize this and stop using the service and the devices fade into obscurity. See CueCat for an example: This *might* have been useful and *might* have defined a paradigm for website tie-ins in print media, except that the User has to register with zip code, gender, and E-mail address, and the vendor has to purchase a code. Little or no functionality and registration required.

    Companies are drooling over this IOT stuff because they see it as a subscription model and they can sell the user info for even more money, but they don't realize that there is no real value being given in exchange for the subscription. There's really little value in being able to turn your furnace up/down remotely, or unlock your door remotely, or start your dishwasher remotely... and absolutely no reason to do this under a subscription model.

    Joel Spolsky's term for this is "feeble business idea". The attractiveness of the model outweighs the impracticality of the solution.

    And THEN you hear a 15-second canned carrier message "[Phone number] is not available right now. Please leave a detailed message after the tone. When you have finished recording, you may hang up, or press pound for more options. To leave a callback number, press 5.”

    That extra 15 seconds is annoying as hell to wait out, and it's only put there so that the carrier can use up metered minutes on an artificially scarce resource.

    Then when you go to *play* the message, you have to wait through the "First message, from, phone number xxx-xxx-xxxx, received at ".

    The old-style was much more convenient. Leave a message *beep* "Hi, this is your sister, please give me a call". Oftentimes 10 seconds *total* gets the point across.

    The new-style - not so much.

    Take the time wasted on each worthless recording (15 secs), multiply by the number of messages each year, and you get a *lot* of wasted man-years.

    And once the batteries reach end-of-life for automotive uses, they can be automatically repurposed for off-grid storage.

    Once battery capacity falls below a certain level (60% perhaps?) it becomes unsuitable for automotive use, but could be used for other purposes such as offline-grid storage. A factory floor filled with older batteries still has quite a bit of capacity - so long as you aren't overly concerned about space or weight efficiencies.

    Battery arrays could be installed at wind and solar installations to act as online storage to help even out baseline demand, and as more batteries come available we simply(!) swap out the oldest/least capacity units.

    ...for some definitions of "simply". In principle it doesn't sound too bad - a computer system monitors all batteries, using robots to install and harvest the batteries. Similar to the ones used for automated greenhouses or the ones that service the amazon fulfillment centers.

    If you agree with this position, then it's OK for police to shoot an unarmed black man in Ferguson Missouri, or a black man purchasing a gun off the shelf at WalMart, or a 12-year old boy in Ohio playing with a toy gun.

    When the department says that the most dickish possible way is the right response they are alienating the people. It might avoid getting the cop thrown off the force, but in the future the department may actually *need* the support or cooperation of the people in order to do their job. This is short-term smart and long-term stupid.
