  1. Amazing view of modern technology on Take a Visual Tour of CyberKnife Radiosurgery (jeffreifman.com) · · Score: 4, Interesting

    Jeff,

    Thank you for the description of your treatment and the equipment that was used. It's amazing where medical technology has come to and the hope that it can provide.

    Last year, my son was treated for stage three non-Hodgkin s lymphoma with just chemotherapy and (thankfully) no need for surgery.

    Good luck and I hope for complete remission.

  2. For personal energy, I would recommend B-12.

  3. To demonstrate the technology, transport cargo on The Race To Create a Hyperloop Heats Up (wsj.com) · · Score: 1

    I'm probably being Toronto, Canada centric but when I look at the number of 18 wheelers travelling between Windsor, Toronto and Montreal (520 miles a bit longer than LA to San Francisco) I would think that a hyperloop with the 401 highway, eliminating big rigs, would make a lot of sense in terms of reduced traffic, wear on the road and truck/driver costs.

    According to http://www.thetruckersreport.c... it costs $1.38 USD/mile and let's assume that each truck is carrying 100,000 lbs of cargo. Along with that, there are 10k trucks travelling the route (https://canadaalive.wordpress.com/2014/01/18/highway-401/) for a total cost of $7,280k per day or more than $2.6B per year.

    Going back to Musk's estimate of $6B for LA to SF, I think that the Windsor to Montreal route could be done for a similar amount (ie quite flat with no mountains and no earthquakes) which means that a 5 year ROI could be conceivable for putting a hyperloop between Windsor and Montreal (with a stop at Toronto) with the bonus of less traffic jams.

    Why isn't somebody this analysis for LA to SF or other city pairs where's there's lots of commercial truck traffic to validate the hyperloop process and demonstrate a track record and demand for passengers?

    Seriously, while a couple of the accidents listed are acts of God and could have happened anyway, many of them, from the human gene pool perspective, deserved to die.

    Putting a gun to your head while taking a picture? Turning your back on bulls and or bisons? Having to be told to NOT touch or hug tigers? I do agree with Disney on their policy however, as a selfie-stick on a ride is most likely to hurt somebody behind the person taking the shot.

    Sorry, for the sake of the human species, these people should be allowed to remove themselves from the reproductive population.

  5. Career step to having your jokes retweeted on An Algorithm To Stop Joke Plagiarists · · Score: 3, Insightful

    Hasn't comedy *always* been the domain of people stealing jokes with the successful people being able to fit them into their own styles with their own humour?

    It's not like stand up comedians like:
    - Rodney Dangerfield
    - Joan Rivers
    - George Carlin
    - Jerry Sienfeld
    didn't have their jokes repeated endlessly as well as use other people's jokes as part of their career. I have seen all four listed above live and they all did jokes that I've heard from Groucho Marx, WC Fields, Abbot & Costello and others (who probably stole them originally).

    It's a hard living and even if you are successful you have to deal with the likes of parasites like Josh Ostrovsky and Jackie Martling while finding other people's jokes and routines that fit into your persona and act.

    It's a circle of life thing.

  7. Not a "Design Flaw"/a Testing Flaw on Backwards S-Pen Can Permanently Damage Note 5 · · Score: 2

    I can see that most of the comments are referring to this as a design flaw and overly complicating the product but I imagine this was put into the Product Requirements Document as a feature that provided some benefit to the customer.

    The issue really is, what was the testing protocol put in place, I would think that with something like this, the Samsung engineers would have to check for:
    - The S-Pen being put in backwards and twisted to the preferred orientation
    - The S-Pen being damaged and put in the right way and backwards and turned away from its preferred orientation
    - Something other than the S-Pen being put in.
    - The S-Pen being inserted with the force of a jackhammer
    - The Galaxy being dropped (on all of its axis) with the S-Pen inserted correctly and incorrectly
    - etc.

    These tests should have been part of the product test and qualification plan.

  8. I should also point out... on Windows 95 Turns 20 · · Score: 1

  9. "Start me up" - What was Gates thinking? on Windows 95 Turns 20 · · Score: 4, Interesting

    IIRC, Gates paid the Rolling Stones $12M for the rights to use their song "Start me up" which to this day I don't understand why he'd pick a song with the lyrics "You make a grown man cry!" in the chorus.

    Trying to install Win95 on a Win 3.11 machine of the day certainly lent itself to tears. I don't think I was ever able to successfully do it (I reverted the 3.11 system back and then just went with Win NT and then then Win 2k) - I never used a Win95 or Win98 PC at work or at home.

    A step in the right direction but definitely not an OS that was ready for prime time (sorry for the mixed metaphors).

  10. Fighter "Generations" is a Lockheed Marketing Term on F-35 Might Be Outperformed By Fourth-Generation Fighters · · Score: 3, Interesting

    When reading articles about the F-35, you have to remember that the term "Fourth Generation" and "Fifth Generation" are terms that Lockheed Martin came up with to provide some marketing cachet for the F-22 and F-35.

    There is no strong definition for the term and the best description that I seen is that "Fifth Generation" fighters employ stealth and undetectable communications. This definition is used with the F-35 to indicate that it will sneak up to enemy aircraft and launch missiles before the enemy aircraft know that it is there - the F-35 doesn't have the dog fighting capabilities of the F-22 or that of other fighters.

    People seem to forget that the F-35's capabilities were first defined after the first Gulf War in which F-16s and other fighter-bombers could not detect Scud missile launchers or approach ones that were detected by other platforms before being detected and the launchers moved out of harm's way or camouflaged in such a way that they couldn't be detected. Then deciding that the basic platform could be extended to a SVTOL for the Marines and a carrier aircraft further doomed it's ability to maneuver effectively against other aircraft that were designed for air-air combat.

    Unfortunately, the US(AF) has put all its eggs into the F-35 basket. I don't see there being a lot of opportunities to order more F-16s or F-15s (with the F-22 line shut down).

    This means that in future conflicts, the US may lose the "air dominance" that has been used in war planning over the last fifty years.

  11. Start with this Password Verification Function on The 2015 Underhanded C Contest Has Begun · · Score: 4, Interesting

    I'm trying to remember where I first saw this function (I think it's a pretty common example for security coding seminars):

    int passwordCompare(char* enteredPassword, char* validPassword) {
    int i;

            for (i = 0; (len(enteredPassword) > i) && (enteredPassword[i] == validPassword[i]; ++i) {
            }

            if (len(enteredPassword) == i) {
                    return -1; /* true */
            }
            else {
                    return 0; /* false */
            }
    }

    but, I would imagine that it would qualify as an example for the contest. I don't think it was originally designed to be malicious, but more of a coding error.

    I would expect most of the entries in the contest would be of this variety, something that a (new) coder has put in that works for basic test cases, but has a serious flaw...

  13. They're sorting for "the right" employees on The Challenge of Working At Amazon · · Score: 2

    While I don't disagree with you, there are people who thrive in an environment like Amazon's. Now, most other people would consider the people who are successful at Amazon as "assholes" and I think they'd be right.

    It doesn't sound like Amazon is shy about telling prospective employees what it's like to work there, so, to a certain extent, there shouldn't be any surprises for their employees when they're working there. That doesn't mean that it's not shameful to harass/punish employees when they have unexpected personal challenges and tragedies.

    The good thing about all this is that Amazon is taking the assholes out of the workforce.

  14. Like Microsoft in early days but more organized on The Challenge of Working At Amazon · · Score: 1

    When I read the article, it reminded me of my interviews at Microsoft (Winter of 1985) with regards to the attitude that they had towards employees and work.

    One of the things that I remember being told was that the Microsoft average employee peaked at 25 and left the company at 28 (with a suitcase of cash) to form their own business (or live on a beach). I was being hired to give my all for five years and then take a break. There was a lot of talk about supporting employees to help them work at this pace. What I didn't get was a sense of organization or where they wanted to go; I was being interviewed for hardware design and I got the feeling that they knew they were on top of the world and destined to be there forever, but didn't have a vision as to where they were going/taking the industry.

    Over the years, it seems like Microsoft changed and became more corporate and relaxed but Bezos and Amazon are making this into much more of a cult(ure) with solid plans and expectations. I'm not surprised with their focus on results they are the successful company that they are and I'm not surprised that their employees are burning out and are bitter.

  16. How do you define a "robot"? on MIT Researchers Develop 'Real Steel' Robot With Human-Like Reflexes · · Score: 1

    When I do robot classes and workshops, I define a "robot" as a device which:

    1. Can perform different tasks.

    2. Uses sensors to control its operation.

    These points are pretty common for definitions. One additional requirement that I have seen is "more than three axis of movement".

    From these requirements, I would say this is a robot.

    I don't believe that going to a restaurant and letting them provide meals, lighting, heat/AC actually constitutes reducing the amount of AC consumed.

  20. Easy Conclusion If Perceived Costs & Range Ign on Are We Reaching the Electric Car Tipping Point? · · Score: 1

    Nice to see that electric cars are seen as a viable alternative but I think we're a long way away from the "tipping point" which won't change until consumers attitudes change.

    I can't see electric cars being at the same or less purchase price than gasoline powered cars for some time. Don't forget there is also the cost of the charger installation and this could be a very significant cost for people who live in (rented and owned) apartments.

    Maybe this will change with the $35k Tesla in 2016/2017 but even that is significantly more expensive than a basic Corolla - if the cost difference is $10k and the car is driven 10k miles/year and gets 25 miles/gallon and gas costs $4/gallon and electricity was free, it would take 6.25 years to make up the difference. That extra $10k seems to be hard to justify.

    When I talk to friends/family about electric cars, the issue that always comes up is range. These are people who maybe drive more than 100 miles in a day once or twice a year and this is a huge concern. I don't know what happened with Tesla's robotic replacement for battery packs, but until it is common place or cars can travel 1,000 miles on a charge (and can be charged in less than five minutes) or "Mr. Fusion" becomes a reality, I don't see this not being an issue with the public at large.

    Maybe we could see the tipping point if the price of an electric car was comparable to a gas powered car but I think it will take lower costs and essentially infinite range for it to happen.

  21. Can't this be tested on a Cube Sat? on German Scientists Confirm NASA's Controversial EM Drive · · Score: 4, Interesting

    Just thinking about this, how expensive would it be to create a small, simple satellite, with solar cells, some large LiPoly batteries, a transponder and an EM drive that fires up every time there is enough juice in the batteries to run it for a few minutes?

    Sticking with the 50nN thrust level for 50W of input and assuming that a 1kg LiPol battery has 260Whr available (https://en.wikipedia.org/wiki/Lithium_polymer_battery), that is approximately 5hr of running time and assuming that the satellite is 5kg, there will be a 10nm/s^2 acceleration.

    5 hours is 18,000s so there should be a delta-V imparted on the satellite of 1.8(10^-4)m/s which is tiny (I did say this is a pretty useless drive at the current time right now) but should be measurable or at least noticeable to its relative position to a control satellite that was launched along with it.

  22. Interesting, but still a lot of hype on German Scientists Confirm NASA's Controversial EM Drive · · Score: 1

    This is really amazing and hopefully it is turning into a window into parts of our universe that we've never imagined.

    But, reading the articles, I think we're a long way off from understanding what this phenomena is and how to exploit it practically. Going back over the previous articles, the measured force was for 50 uN from 50W of power - this doesn't seem like a very practical application as yet; the claims of round trips to Mars in less than a year are very exaggerated.

    On that point, I thought we could go to Mars in 3 months or so now; it just takes a nuclear rocket rather than chemical, plasma or EM drives.

    Finally, in the hacked.com article, rather than expelling "propellant", aren't you expelling "reaction mass"?

  25. Rather than extra battery how about a power cord? on Lenovo ThinkPad W550s: Heavy, But a Battery That Lasts Nearly All Day · · Score: 2

    I use a laptop a lot for going out to customers and giving demonstrations and the ideal (for me) would be about 6 hours of so of battery life but I think I would be at the high end of the power curve (requiring active WiFi and Bluetooth as well as the processor/display fully up). For the average laptop, the life I get seems to be around 3.5hours. But, I can't see a larger/heavier laptop with more life would be an big advantage for me.

    What would be an advantage to me would be reasonable life (and 3.5hours seems to fit that need for a single meeting/session) with the ability to plug into an outlet (there's always an outlet around where I am) and car would be of more use to me than a big honking battery that takes a long time to fully charge. This would make travel simpler (don't have to bring along the brick) as well as search into the depth of the bags in a meeting when the seven minute warning comes up on Windows.
