    Self directed/managed teams are not new. However to be successful the team must consist of people with high expertise in the various areas where things need to be done. Plus they need to have goal oriented personalities and be team players, willing to do a dirty/uninteresting task at times to get the team to where it needs to be. And most importantly open minded when discussing how to solve a problem, complete a task, etc amongst fellow team members, willing to put one's own idea aside and adopt a colleagues. In other words this sort of structure is not for most people. It can work but the team members must be very carefully and thoughtfully selected.

    Again, he's not mixing up moles and liters due to scientific illiteracy. He's substituting a term well known to the public for a term largely unknown to the public. Its called artistic license, its a mass market book and movie, its not a scientific paper. Such things are permissible. Also hard sci fi recognizes artistic license and the limits of the audience, the rule of thumb of hard sci fi is plausibility not literal adherence to known science.

    From wiki: "Today, the term "soft science fiction" is also often used to refer to science fiction stories which lack any scientific focus or rigorous adherence to known science. The categorization "hard science fiction" represents a position on a broad continuum—ranging from "softer" to "harder".

  6. The movie skipped many months of activity ... on Review: The Martian · · Score: 1

    I liked the movie a lot, and I was surprised about how almost everything in the book made it into the movie.

    Actually quite a bit was left out. In particular note the "7 months later" notice that is briefly on the screen.

    Was it 7 or did I misremember the number of months? In any case many months of activity and drama were skipped. If someone reads the book after seeing the movie there will be plenty of new interesting stuff.

    Still, a very reasonable compromise given time constraints and overall a very good adaptation of a book IMO. Only one somewhat regrettable hollywood'ism near the end of the rescue. Quite forgivable given the quality of the reset of the movie.

  7. 401K does not require investing in stocks ... on Review: The Martian · · Score: 1

    Ah, yes. 401(K)s. I sure want to put my retirement in the hands of the same people who created a bubble market in the US ...

    You do realize that investing in a 401k does not require you to invest in stocks and bonds? An interest bearing cash option is available, much like a savings account. Even with the historically low average interest rate your return will most likely outperform social security, especially with employer matches.

    Of course if you are decades away from retirement bubbles aren't a problem. When stock prices crash when the bubble breaks your 401k deductions are buying stocks at a cheaper price. That 2007 crash, any stocks you owned already were recovered in about five years judging by the DOW and S&P500 indexes, anything purchased in that timeframe was at a discount and showed a huge gain. Using a NASDAQ index your recovery would have been a little faster. And FYI, you don't have to pick stocks of companies - guess at winners and losers, you can invest in funds that track the previously mentioned indexes. The "averaging in" that occurs via your paycheck's 401k deductions moderate and average out a lot of market volatility.

    So no, you are not highly vulnerable to the idiots on wall street unless you try to play their game, pick winners and losers rather than go with an index fund, or are less than ten years from retirement and needing the money.

  8. Lower tax rates fine if loopholes closed ... on Review: The Martian · · Score: 1

    What, as opposed to the bullshit claim that by cutting the taxes of corporations and the wealthy somehow that improves everybody's lives?

    Actually cutting taxes and closing loopholes could work quite nicely, the later offsetting the former, generating the same revenue for the government.

    What does not work so well is what we are currently doing. Having high tax rates and lots and lots of loopholes. The former allowing some politicians to make "we're getting money from the rich" claims while the later simultaneously lets corporations and people not actually make those payments implied by the former.

    The current system is an incredible engine of corruption. Letting politicians created special taxes, tax exceptions and various loopholes is license to punish opponents and reward friends. That's one of the benefits of some flat'ish tax system (not literally flat, phases in to give those of lower incomes a break) with no deductions. It prevents politicians from engaging in social engineering and political corruption via the tax system. A lower rate does not have to generate less revenue. Take current revenue, calculate the effective tax rate after credits and deductions, make that the "flat" rate with no deductions (again, slightly more complicated than that since it phases in to give lower incomes a break but its still an easy computation for macro economists). Lower rate, same revenue.

    Well any equipment dealing with water ice would be in the shade and not subject to lunar temperature extremes, that is how the the ice has survived after all. As for equipment on the surface exposed to sunlight, go underground or make shade. There are lava tubes in places waiting to be used. Or one can build walls from the lunar regolith. Or one can put up a tarp like when camping in the desert, no wind on the moon so its more practical than on mars. The lunar regolith has the advantage of also helping with micro-meteors and provides some radiation shielding.

  15. Impact energy distributed on Tank Hack Ensured Farmland Didn't Thwart the Invasion of Europe · · Score: 1

    These hedgerows were not what people in the US and UK think of when someone says hedges. That was part of the problem, people in the US and UK were not used to seeing vegetation that tanks could not knock down or plow through so it was a blind spot of sorts.

    These hedgerows were incredibly large and dense with branches, vines and roots interlocking. When they took a hit from a tank the energy of impact would get distributed, its a little bit like the special fibers and weaves that help to distribute impact energy over a large area in some bullet resistant vests. They needed something to cut these branches and vines to interfere with this energy distribution.

    Or maybe think of a net, one wants to cut a slot in the net to pass through.

    The hedges were generally at ground level but the roads were often sunken. Traveling along these roads was dangerous. That was expected, that was where all the weapons were pointed. To maneuver freely, off-road, one had to get through the hedgerows.

    With respect to German 88mm guns it didn't matter where the US tank was hit, they didn't need to hit the thinly armored bottom. Those guns were exceptionally deadly and were waiting for tanks to drive down the road. I recall reading a US veteran's recollection. The US soldier was annoyed at the smug look of a captured German officer. He asked the German if they were such supermen why was he a prisoner. The German responded in English: I commanded an 88mm gun battery. Every time an American tank came down the road we destroyed it. Eventually we ran out of ammunition, you did not run out of tanks.

    Being a US tanker in the European theatre was extremely hazardous. You really didn't want to be seen or travel where expected. Roads, at ground level or sunken, were dangerous.

    It is engineering - they're operating, maintaining, and modifying machines with engines. There's a handful of clowns out on a "we need REAL engineers" campaign on Slashdot, yet they don't know WTF a real engineer is.

    Actually I'm quite familiar with the more archaic definition of engineering. My grandfather was licensed to operate and maintain various types of machinery in that domain. For example a stationary engineering license to operate a power plant in an industrial setting, i.e. boil water, produce steam, drive turbines, etc. "Stationary" to differentiate it from railway locomotives, locomotive engines, ship propulsion, etc.

    However in either the more modern or more archaic usage of "engineering" the word does not apply to this Normandy event. It was truly a hack. A complete jury-rigged improvisation with materials at hand, something expedient for the field for now. "Engineering" would be more appropriate for something with a little more design and/or a more long term solution. Later more robust engineered variants of this idea would appear.

    Not "engineering" in the sense that engineers at a company came up with the device. The phrase "hack" is entirely appropriate. This modification came from a Sergeant at Normandy who thought he could cut up some of the i-beam based beach obstacles and make "teeth" for the tanks. So the solution came from the blacksmith/welder types, an actual Army MOS, improvising something on the spot not the engineers designing something to meet a requirement.

  23. Re:You misrepresent the F-111 on The WWII-Era Inspired Plane Giving the F-35 a Run For Its Money · · Score: 1

    Except you would be wrong. The Air Force wanted an aircraft that could serve as a fighter/bomber, and the Navy wanted a fighter/interceptor to defend Carrier task forces against Russian bomber/cruise missile attack swarms. McNamara made them combine their requirements into the "Tactical Fighter Experimental" (TFX) program, and it was a "fighter" in that it was intended to use missiles at range to shoot down enemy aircraft, in an era where dogfighting was considered to be obsolete.

    No. The Air Force's primary interest was that of a bomber, and the Navy that of an interceptor. Fighter was a very secondary thing. Much like the F-117 can mount sidewinders for air-to-air, or an A-10 for that matter too. Its more a self defense thing. That does not make an aircraft a "fighter". Note the distinction between "fighter" and "interceptor", the later has more to do with taking out big slowly maneuvering bombers. The F-111 was actually envisioned as an answer to both sides of this traditional "interceptor" mission. For the Navy it attacked the bombers. For the Air Force it replaced the big low maneuverability bombers at altitude with small fast terrain hugging bombers, aircraft far more likely to find gaps in Soviet air defenses.

    The F-111 was never intended to be a front line fighter like the F-4. And it was the F-4 in that era that was intended to be a front line fighter that shoots down enemy fighters at range with missiles. Early F-4 versions did not include guns.

    Meanwhile, the Air Force would use it mostly as a tactical bomber, and also made an adapted version to use as a strategic bomber, and it did a pretty decent job of those - but it could have done much better had it been designed to do just that rather than trying to be everything to everyone.

    That was the role the Air Force had always been working towards. And not everything, not a "fighter", just a bomber and and "interceptor". Again an "interceptor" is not a "fighter", different prey so to speak, primarily targeting bombers and such.

    And I can only imagine what would have happened had the Marines demanded it be SVTOL capable, too.

    To be clear I am not in favor of multi-mission aircraft. I prefer the 1970s renegade sort of approach that led to the single purpose designs of the F-16 and A-10. That is not to say there isn't more opportunity for common components. We probably could have more standardization and commonality with respect to avionics, maybe more aircraft sharing engines.

    STOVL would probably have to be its own single purpose design, its hard to imagine vertical landing being a general purpose win over ruggedness. Or maybe it would be a better idea to adapt amphibious assault ships for STOL (no vertical). No need for the complex arresting gear of a carrier that supports many aircraft types. Maybe something simpler for a single type of aircraft, whatever STOL the Marines are operating. I understand OV-10 have been launched and recovered by assault ships but something closer to an A-10 would be needing more runway so arresting gear of some sort would be necessary.

  24. You misrepresent the F-111 on The WWII-Era Inspired Plane Giving the F-35 a Run For Its Money · · Score: 1

    You seem to be making the common mistake that an "F" designation necessarily means the aircraft is a fighter designed to mix it up with other fighters. That is not true. Sometimes tactical bombers get the "F" designation, F-111 and F-117 for example. The F-111 was designed for deep strikes behind enemy lines behind a defensive line of fighters and surface to air missiles. The idea was that extreme low altitude flight, computer assisted nap of the earth, would allow the F-111 to avoid SAM radar; and that high speed at these altitudes would help to avoid fighters which were generally less capable at low altitudes. That was the "intent" of the F-111, it was not an F-4 replacement.

    Now the F-111 may have also had some fighter roles in mind, but such were more like intercepting Soviet bombers coming south from the north pole. Or in the Navy's version of the scenario intercepting Soviet bombers heading towards a carrier. Note quite a fighter-on-fighter scenarios.

    For the record, fighters do even worse against IADS. See WW2, Korea, Vietnam and various Arab/Israeli conflicts. The A-10 was designed with the lessons of these wars in mind. Nap of the earth flight, ruggedness, etc.

    Drones have their utility but they are not a complete replacement. Well maybe for the F-35, given that it will probably be required to operate at higher altitudes and such given the previously mentioned weaknesses of fighters in the CAS role. However for a low, slow highly maneuverable aircraft with a pilot with a head on a swivel and who understands infantry operations and can evaluate what he sees at a glance the drone can come up lacking. The drone is no "magic bullet". We also need a manned aircraft like the A-10 as well.
