  1. How to get rid of the free upgrade icon? on Features That Windows 10 Will Deprecate · · Score: 4, Insightful

    I have a win7 home machine. Suddenly this icon "free upgrade to Win 10" has popped up next to the clock in the notification area. It pops open a window that says, " it is not a trial version. It is the real deal. Click now and we will download and upgrade you to win 10 when it is released". There is no way to dismiss the icon and stop it. I am not going to upgrade, not with the subscription model they seem to be moving to. How do you get rid of this icon? Worried my better half might click ok by mistake thinking it is a good deal.

  3. Fusion? done thing. Why reinvent the wheel? on Mystery Company Blazes a Trail In Fusion Energy · · Score: 5, Insightful

    We already have a fusion reactor, that pumps mega-giga-tera watts of energy and works without any serious maintenance issues. Just improve the ability to collect its output, some capacity to smooth out the fluctuations in the collection. It is a stellar idea, but I don't know when it would dawn on to the general public.

  4. Re:Jesus on Scientists Discover Sawfish Escape Extinction Through "Virgin Births" · · Score: 3, Interesting
    The title needlessly brought in "virgin birth". There are other scientific terms, like asexual reproduction, parthenogenesis etc. So take your beef to the editors needlessly adding a religious color to some innocuous scientific observation.

    Also I have been around enough theists who would take a random scientific fact and argue it was predicted in scriptures. "Koran has referenced this fact of embryology" "Bible has always known the world was round" "The Manduk Upanishad has a verse describing the Schrodinger's Equation" "The fundamental particles electron, proton and neutron represent the Holy Trinity" "The Shaivaite philosophy that holds the dance of Shiva permeates the universe and is the fundamental cosmic energy is same as molecular vibrations providing temperature/heat energy in thermodynamics".

    Score card?

    The atheists are woefully outclassed by theists when it comes to linking random collection of (often inconsistent) scientific facts to religious principles to bolster their point of view.

    Unless the device makes insulin on demand, it ain't artificial pancreas. It releases insulin stored in a tank, mimicking the action of the pancreas, but the tank has to be refilled from external sources of insulin. But still it is a great advance.

    Intel chips provide 80 bit floating point registers, but the storage is 64 bits. GCC would let you compute all calc in 80 bits all registers are loaded with 64 bit fetch and final result is stored in 64 bits. Intermediate results are 80 bit accurate. Some carefully written expressions can limit their truncation errors.

    This is well known. I had a bug in a tree class due to this. The key stored in the instance was 64 bit, but the compare class evaluated and compared it in 80 bits. One of the most difficult bugs I ever encountered. Highly recursive calls to the compare function failing once in about a billion calls... But that was almost 10 or 12 years ago.

    But one thing. GCC handled the truncations correctly. It allows the 80 bit evaluations turned off by compiler options. I don't mix GCC with msvcrt so I am not sure how old / new this is. My 80 bit adventure was in Linux on Intel chips.

    .. to what what industries get out of government. Heck, some oil tycoons saw the first gulf war where USA kicked Saddam out of Kuwait, and figured it would be a cakewalk to kick him out of Baghdad and install some puppets and get all the oil in Iraq on the cheap. Got two oil men elected as POTUS and VPOTUS, launched a smoke and mirrors campaign and got us into a war that has taken 1 trillion and counting. If the gamble paid off, they would have gained a few billion dollars. But it didn't, but they didn't lose 1 trillion dollars we, the taxpayers did.

    Compared to the shenanigans of the coal and oil businesses, even if it is true, this 5 billion is nothing. But most likely it is a hit piece commissioned by the same people who brought you the Iraq war. That one was expansion attempt. Now they are defending the home turf, public utilities using gas and coal. Entrenched monopolies who have never faced competition, lightly regulated by revolving door politicians, lobbyists and company men.

  17. Unlimited 4MP pics on Google Photos Launches With Unlimited Storage, Completely Separate From Google+ · · Score: 1
    Google backup storage is 15 GB free shared across all Google+ products. Google docs, drive, photos, chats etc etc. Photos below 4MP (Says 2048 x 2048 instead of 4MP dont know why) resolution does not count against the quota. Higher resolution pics count against your quota. Storage price is 2$ per month for 100GB and 10$ per month for 1 TB. Need a credit card and auto recharge every month.

    The price is not bad, but auto charge every month is a pain. I usually don't leave any active credit card number attached to my accounts (amazon or google wallet or ...) for long. Used to create virtual numbers with dollar limit and leave them on. But citi virtual cards numbers are usable by one merchant per number. Amazon has so many entities it is a pain dealing with mismatched virtual numbers.

    Should create a virtual number for my google wallet with a low limit like 1000$ or so. It is crazy what laziness does to you. My IPass is on auto recharge, they don't send monthly statements, they take two to three days to post the charges, so you cant check the charges as soon as you return from a trip. Three days later you forget and you get lazy to log in and check the transactions.... Knowing how lazy I am, I am very wary of leaving an active number on a web account. Protection against being hacked and charged tons of money is purely an added bonus.

  18. Re:It's always Stage III on Third Stage Design Problem Cause of Most Recent Proton Failure · · Score: 1

    I think too, not sure, but with the third stage usually you're fully ballistic when it's running. (don't need to fight gravity)

    Earth's gravitational field is so vast, it has the Moon in its clutches, you never get so far you don't feel gravity. The term escape velocity much misunderstood, you don't escape Earth's gravity. It means the centripetal acceleration (v/r) is greater than gravitational acceleration. It means the orbit is not a closed curve (ellipse) but an open one (parabola or hyperbola). After some altitude the air resistance falls to near zero and you don't have to fight the drag, that is all. Also the term ballistic comes from the word "ball", as in cannon ball. The study of trajectories of cannon balls, shells etc. In the ballistic stage of the flight, there is no thrust from the rocket engines and the vehicle moves purely like a ball shot of an artillery piece, governed by gravity and air resistance.

  19. If that is true, OO-COBOL wil rule you all. on The Reason For Java's Staying Power: It's Easy To Read · · Score: 1
    COBOL was designed to have readability as an end goal, more than even performance. Those days there were countless stories of computer wizards stealing fractions of pennies per transaction and committing million dollar frauds. It was designed to have "functional analysts" who define the business rules, laws to be obeyed and regulations to comply with and the "technical analysts" who will supervise the coding teams. The aim was for the legal and financial expert to read the code and approve.

    When the object oriented craze took off in 1990s, we were joking, next thing you know you would have OO-COBOL. And next thing we knew we had OO-COBOL.

    All of us know the staying power and entrenchment of that language designed specifically for readability.

    There was a time auto makers would make their car radios in such a way after market car stereos would be too expensive and/or impossible to mount. Enjoyed nice profit margins there. Eventually the mounts and connectors were standardized and the automakers lost that segment. But they never lost that mentality. Build in a GPS system and demand 200$ or 300$ to upgrade the maps-DVD-ROM. Now a days I see a few four/five year old Benzes and BMWs with plastic iPad/smartphone holder on the dash. These auto companies are used to product cycles stretching into a decade and vendor lock on accessories.

    Pretty soon nobody will buy a car if they can't swap in their own entertainment system, their own map/nav system. That profit center is gone, these auto makers have to wake up and realize it.

    The auto makers are so averse to competition and openness. How old are wi-fi enabled standalone network file servers? Why didn't they build one in to the cars, as you drive into the garage it logs into the router, synchs playlists, music, pod casts, weather reports, map information and is ready to go out with the latest info saved in a had disk? They could have done it 10 years ago.

    They hate electronics and hate electrical engineers. The petrol burning engineers seem to have a snooty attitude towards the electrical engineers. They could have removed the first gear ages ago. Just spruce up the starter motor to make it strong enough to move the car to 2 mph using amped up power from the alternator. Couple the wheels to the IC engine mechanically on the second gear. That would eliminate the low end torque requirement and they engine could be tuned differently for fuel economy, peak power at a different rpm etc etc. Much of the fuel economy of the Prius comes from having an IC engine that does not have to move the car from 0 mph.

    Of course, I am talking with 20/20 hindsight. But I am not a professional auto engineer. It is their job to have thought about it ages ago. Railways were big in 1950s and 60s. General Electric made a killing replacing all the steam locomotives with diesel-electric locomotives in just one decade. So fast some of the gleaming steam locomotives made just one run, from Baldwin Loco Works, Philadelphia to the scrap yard. Seeing how the torque problem in the locomotives is solved using an electric motor they did not make the connection and try to replicate it in their automobiles. They only were interested in pissing contests involving the sizes of the engines. 4 liter engine, 5 liter, 6 liter. 8 cylinder, 12 cylinder... More and more complex transmissions, clutches, slip rings, torque converters... all pure mechanical systems. Could have been replaced by one clean electric motor. The diesel-engine-generator and electric motors in the locomotive are just torque converters. But no, they would not even think about it.

  25. Re:Cost bigger issue than sonic boom on Rockwell Collins To Develop Cockpit Display To Show Sonic Boom Over Land · · Score: 1
    Thanks for the correction. I missed it by a factor 1000 in power estimate. But I also lowballed the area by orders magnitude. Plane at 6 miles altitude, sonic boom energy is spread over a conical surface of base radius 10 km, area of at least 300 sq km. Wind energy goes as the cube of velocity, (squared in the kinetic energy term, and linear in the mass flow rate term). So at most it will be compared to a breeze of 12 or 13 mph rather than 10. But that is about all.

    Still feeling like a chump for missing the energy estimate by a factor of 1000.
