In this task, you are given books product reviews in English language. The goal is to classify the review as "POS" if the overall sentiment of the review is positive or as "NEG" if the overall sentiment of the review is negative.

Q: GREAT overview-awful editing &amp; proofreading . As previous reviewers have commented, this is a very good overview of the CMMI. The authors work in the industry, and have done an admirable job presenting the nuts-and-bolts of this enormous topic in a straightforward fashion. But if you intend to use it as a tool, like you would Paulk's book on the SW-CMM (SM), DON'T BUY IT YET. The editing in Appendix B renders this book useless to me (I need it as a tool). When I compare the constituents of the Process Areas in Appendix B to the CMMI (CMU/SEI-2000-TR-018), there is erroneous duplication. E.g., &quot;Commitment&quot; in PMC reads exactly like &quot;Commitment&quot; in Requirements Management PA (it shouldn't !). Ditto for Co in SAM, Co in MA, and the subsequent Maturity Level 2 Process Area commitments. The same erroneous cut-and-paste was made for the Abilities, DI, etc. The Level 3 PAs have the similar problem, erroneous cut-and-pastes from the RD template. I cannot use this book as I'd intended because of these errors, so I have to lug around the large heavy SEI tech reports instead

Q: Get Out Your Plow and Harness Old Nellie . ...to get a little tilling done before someone steals and eats her.    I chose this book for my second read on this subject because it has the highest ratings (on subject) on Amazon.  Heinberg has done a thorough job of discussing every aspect of the coming problems to society due to a lack of petroleum - most of which I had never considered.  Literature about this are from the point of view of either the politician, the economist, or the geologist.  He takes the view of the geologist and the future does not look good.      I hold a more positive view: that human ingenuity will prevail - but I could easily be wrong.  In any case, this is a worthwhile read for anyone.  Of particular interest is the chapter that deals with alternate energy sources.  The next time you read about an alternate energy source in the news, you'll remember the real pro's and con's from an expert.    Quick synopsis of 41 page alternative fuel chapter from "Party's Over:"    Natural Gas:  Cannot be shipped from overseas easily like oil - is more difficult to extract economically every year - is being depleted like oil.  In view of the precarious status of North American gas supplies, any attempt to shift to NG as an intermediate fuel would waste time and capital in the enlargement of an infrastructure that will soon be obsolete.    Coal:  Shortage not so much a problem, however, its EROEI (Energy Return On Energy Invested) and pollution are a problem.  As the richer seams are exhausted, it may cease to be a useful energy source within only 2-3 decades.    Nuclear:  Electricity from existing nuclear plants is inexpensive, but only if direct costs are considered.  When adding in plant construction, safety, reactor decommissioning, and waste storage - nuclear power is very expensive indeed.  There are currently 442 reactors operating worldwide.  France in the only country in Europe still building them.  Only Asia expects to expand significantly.  Only a few of the highly touted fast breeder reactors have been built, and they have proven to be prohibitively expensive.  The US currently processes enough uranium to fuel existing US reactors for the next 40 years.  The mining process is wasteful, polluting, and dangerous. When all things are considered, the EROEI on nuclear energy is fairly low and there is significant intangible downside.    Wind:  Of all renewables  (not depletable), wind power usage on a global scale is being developed the fastest.  Technology has advanced - it no longer kills birds because it uses slower fan speeds and the fans are mounted on a vertical axis. It can operate in more variable wind speeds and the cost is declining rapidly.  Soon your own equipment could be bought and used on your own property.  Wind has the best EROEI and Germany leads the world in its usage.  On a large scale, wind power would require vastly new infrastructure, but it is the most practical alternative so far.    Problem: cannot easily be converted to fuel transportation and agricultural needs.     Solar:  Technology advancing rapidly, photovoltaic the best so far.  Research is advancing into diverse methods of collection, including such easy methods of application as solar buckyball collectors incorporated into house paint.  Tremendous potential, would need new infrastructure.  Problem: cannot easily be converted to fuel transportation and agricultural needs.    Hydrogen:  For now, the process of hydrogen production always uses more energy than the resulting hydrogen will yield.  For one thing, hydrogen is not an energy source, but an energy carrier.  It's production depends on continued usage of the dwindling supply of natural gas.   There is new technology, however, and reason to be optimistic.  As with wind and solar, a whole new infrastructure, requiring time and investments of huge amounts of money and energy technology are necessary.   Like wind and solar, hydrogen fuel cells should be central features of our plans to phase out petroleum.  We should be dramatically increasing these investments.    Hydroelectric:  In many regions of the world - and especially in the US - it is already thoroughly exploited.    Geothermal power, tides, and waves: limited application in limited regions of the world.    Biomass: wood burning - pollution and limited resources in a world with 6 billion people - imagine the world being one big Easter Island.    Ethanol: costs more energy to produce than it eventually delivers to society.  Brazil is the poster child, but is burning down rain forests to grow sugar cane.    Cold-Fusion: pseudoscience    Conservation - Efficiency and Curtailment:  Will be crucial in cushioning impacts from the depletion of oil.  But it is not a panacea - even when you ignore cheaters (individuals and countries).      Saudi saying:  My grandfather rode a camel.  My father rode in a car.  I fly a jet airplane.  My grandson will ride a camel.

Q: "A dark wind has entered his soul" . "Enemies unseen... Fears unspoken...... A dark wind has entered his soul"     Navajo Tribal Police Sgt. Jim Chee seems to be batting zero; so far he has not been able to solve a series of seemingly unrelated crimes. In an area that was joint use land between the Navaho and the Hopi (now Hopi) Sgt Jim Chee is given the task of finding the vandal that keeps destroying a windmill placed there to make Hopi life easer. He hears an airplane landing in the dark of night with no lights. The plane crashes and leaves a dying pilot. Also a dead man sitting up against a rock with a note in his hand saying if you want it back contact...    Sgt Chee is told that it is probably drugs and federal jurisdiction. Chee is not supposed to go anywhere near or have anything to do with the case. He has his own problems with the mill, a missing thief, and a mysterious ritual death. Naturally he listens, and can not help it if they overlap.        One of the reasons for reading Hillerman's books maybe more important than the overlying mystery is the descriptions of the area and the Ways of the Navaho and Hopi. Hillerman suggests you also read "The Book of the Hopi" by Frank Waters.    Not as intricate as the book but still fun is the movie "Dark Wind" (Lou Diamond Phillips as Officer Jim Chee, Fred Ward as Lieutenant Joe Leaphorn
