1.0 out of 5 stars Very disturbing flick don't waste your money nor your time (terrible movie) I'd give it negative stars if I could., September 23, 2014
Verified Purchase(What's this?)
This movie is very disturbing. I recommend it to no one, and I'm sorry I watched any of it... yes, turned it off before it was over (almost never do that) and I don't even care how it turns out!
Don't waste your money, or your time. This movie was aweful !

Blah

3.0 out of 5 stars For the price its just ok, September 23, 2014
This is a cheezy piece of plastic made somewhere in China, substandard construction (the guts) with small difficult to see and manipulate keys. The cursor and four function keys are shiny silver and very difficult to see. The divide key is too close to the 'clear' key, and if you're not careful you're whole problem is gone. The cursor key is very inferior as compared to the 84+ or the 89. The calculator is non graphing and non programable, which makes it almost worthless. Its multi-touch keys can be a pain in the neck, and other than that its just mediocre.
On the positive side it sports some phenomenal features for the price as far as scientific calculators go. I way prefer my Casio fx 260 Solar by far, and in comparison the only thing the TI36x Pro has going for it over the Casio fx 260 is the four line sixteen digit display.
Now for the negative: the machine has a programming problem (say bug) which is triggered by using the mixed number conversion routine [math] [1] [enter]. Once this has occurred mixed number problems containing PI will incorrectly give a mixed number with PI in the numerator of the fractional part (which is totally bogus). I have verified this bug on my new purchase (date 9-22-2014) which can be reproduced like this:
Clear the memory with a reset, or hold the 'on' key while pressing the 'clear' key, and then press 'clear'.
Type [math] [1] [enter]
will give 0
Type PI 12.5 ^ 2 [<>] [enter]
will give 156 PI/4 which is completely wrong

The problem will persist until the machine is reset, or the memory is cleared (same difference).

To avoid the problem DO NOT use mixed number conversion with PI, and be careful to clear the machine (or reset) before doing PI calcs if you have EVER done a mixed number conversion.
(OR)
With the MODE settings select Classic rather than MathPrint. This will prevent the problem altogether; however, some of the 'feature' of the calculator is then lost.

All in all I'd give this silly thing three stars (I like the machine because I collect calculators, but I wouldn't recommend it to anyone else).

The bug in the calculator will be a fit for students, especially if they are flying along and not paying attention; it will bite them! ouch.

In comparison to any of the graphing calculators this machine is a piece of junk; physically, and technically.

4.0 out of 5 stars Excellent Read : British Contribution(s) to Computer Science (The Turing Enigma), January 10, 2014
Most computer science history books focus on the American contributions to the field (ignoring mostly the primary contributions made in the United Kingdom). This book is a breath of fresh air in that regard; the British story is told with lucidity and clarity. I recommend reading the book along with George Dyson's "Turings Cathedral". Between the two books one gains an outstanding understanding of the driving forces at work in the development of the stored program computer.

While this is not the most outstanding biography of Turing (see Hodges' work) it is an outstanding literary contribution to the story of the advent of the stored program computer created at Manchester University, and how Alan Turing contributed to the drive behind achieving a stored program computer (and the possibility of artificial intelligence).

This work is one of the very best descriptions of the theoretical working of an a-machine (Turing machine) that I have ever read in the popular press (seriously). The chapter "The Universal Machine" is really quite good. Leavitt's description of how Alan Turing used his a-machine concept to solve the Entscheidungsproblem in the negative is outstanding; as well Turing's relationship with Alonzo Church of Princeton and the correlation between Church's lambda calculus and Turing's a-machine in solving the same problem independently at the same time.

The historical writing behind the Bletchly Park "bombe" and Turing's role in cryptanalysis is spendid, as well Turing's role unraveling the German "enigma" machine as it pertained to the overall history of the advent of early computing is also quite well done.

I was afraid, frankly, that the work might focus on homosexuality (not only because of Turing's preferences, but because of the author's preferences) and that the homosexual agenda might overwhelm the overall historicity of the work, or might undermine the technical side of the computer science writing. I was surprisingly refreshed to find that this was not the case. Yes, Turing's sexual preferences would have ranging complications and consequences (and the author does not shy away from those) but there is a very good balance from a literary perspective (even a historical perspective) with regard to Turing's private side vs. his professional and philosophical side (as a philosopher and as a mathematician. The author makes that statement with regards homosexuality, "its not the thing itself that bothers [people], its having to think about it". This is one of the author's genius points... because he skillfully forces his audience to "think about it," without overwhelming the audience with an agenda. On the other hand the science and the history are portrayed with elegance and style, and are surprisingly accurate.

As a computer scientist myself, and as an historian of early computer related topics myself, I found Leavitt's account refreshing, masterfully told, technically accurate and compassionately rendered. The British certainly deserve more credit publicly for their contributions to the development of the stored program computer, and Alan Turing certainly deserves more credit (even an apology) for the treatment he received following a stellar career in mathematics, the early end of World War II do to his heroic efforts, and his contribution to the computer science we all take for granted today in everything we do... from phone calls and other communication to personal data processing, to the functioning of everyday appliances like our automobiles and refrigerators. Thank you David Leavitt for a positive gift.

The book is a great read, well worth the effort.

2.0 out of 5 stars You've got to be kidding ?, November 11, 2012
I loved the book "Killing Lincoln". O'Reilly (& Dugard) have created a huge disappointment this time around.

"Killing Kennedy" is almost as lame as Mark Fuhrman's "A Simple Act of Murder.

Oswald never fired a shot. Most of the American people who have studied this story for almost fifty years concur. This murder was a conspiracy, with some of the conspirators at the highest levels of government. Even the United States House of Representatives Select Committee on Assassinations (HSCA) finds that the Kennedy assassination was likely the result of at least two gunmen (a conspiracy).

O'Reilly's book places most of the dots on the table (and their backgrounds) and then fails to connect them, as though this has never been researched and completely ignoring *all* of the Clay Shaw prosecution, and *all* of the HSCA proceedings.

The conclusion of this appendage to history is just a lame hanging-on to the bogus Warren Commission findings and almost fifty years of government lying.

Those of us who remember, who will never forget, who have stood for hours at the Kennedy grave-site, who will demand forever an appropriate explanation are well aware that the Kennedy assassination was nothing other than a Coup d'Etat in America, with Lyndon B. Johnson waiting breathlessly in the wings. Stop lying to the American people.

The book "Killing Kennedy" by O'Reilly and Dugard is a disappointing fabrication that adds insult to injury. If you want a blow-by-blow of Kennedy's sex life, an all-but-accusation attempting to pin the murder (I mean suicide) of Marilyn Monroe on Bobby Kennedy, or exposing the sex life of Martin Luther King Jr... (that is really low...) well, the book might be for you. If you want the truth regarding the killing of Kennedy, well, you'll be disappointed.

The only reason I even give the book two stars is that the bay-of-pigs fiasco is mostly accurate and detailed politically. Also Vietnam's Diem is portrayed accurately and politically relevant to Kennedy -- although not quite connecting the dots back to Texas, and Bell Helicopter. (never mind).

If you liked the Warren Report, you'll love this book.
