Cory Doctorow on the new Robert Heinlein biography

RAH by PattersonI finished reading the first volume last night, and I can’t wait for volume two. Cory Doctorow summarizes John Clute’s review with his own observations (Clute compared Heinlein’s work to Doctorow’s):

Heinlein was notoriously recalcitrant about his early life and the two wives he was married to before his epic marriage to Virginia Heinlein. He repeatedly burned correspondence and other writings that related to that period. Clute suggests that this is partly driven by Heinlein’s desire to be Robert A Heinlein, titan of the field, without having to cope with his youthful embarrassments. It’s a good bet — lots of the stuff that drives young people to write science fiction also makes them a pain in the ass to be around until they work some of the kinks out of their system (I wholeheartedly include myself in this generalization).

It’s interesting to see his own growth, from his early priggishness (he was nicknamed “the boy general” as a plebe at the Naval Academy) which undoubtedly was not helped by his health issues and tendency to stammer. He was in the shadow of his older brother Rex Ivar for most of his youth, even following him to the Academy three two years later. Rex Ivar was the favourite child in the family and Robert never seemed to be able to do as well in his parents’ eyes as the older boy.

Robert Heinlein was probably a pretty toxic individual as a teenager, based on the evidence Patterson presents — it’s pretty clear even after most of the information was sanitized by Heinlein’s third wife Virginia. Patterson never met Heinlein, and by the time he took on the biography, most of the people who knew Heinlein were fading from the scene. I think he did a very good job with the information available to him, but the biography definitely improves after the Academy years.

Patterson also puts forward a pretty comprehensive case for the idea that Heinlein’s fiction generally conveys Heinlein’s own political beliefs. This is widely acknowledged among Heinlein fans, save for a few who seem distressed by the idea that the blatant racism and sexism (especially in the earlier works) are the true beliefs of the writer at the time of writing and would prefer to believe that Heinlein didn’t write himself into his works. I got into a pretty heated debate with one such person at the Heinlein panel at the 2007 Comicon, who maintained the absurd position that Heinlein’s views could never be divined by reading his fiction — after all, his characters espouse all manner of contradictory beliefs! (To which I replied: “Yes, but the convincing arguments are always for the same set of beliefs, and the characters who challenge those beliefs are beaten in the argument.”) Not that I fault Heinlein for this — it’s an honorable tradition in SF and the mainstream of literature, and I find Heinlein’s beliefs to be nuanced and complex, anything but the reactionary caricature with which he is often dismissed.

It should be no surprise to anyone over 30 that Robert Heinlein’s political and philosophical views changed over his lifetime. This is discussed in some depth in the book, frequently from Heinlein’s own letters to friends at various points. He lost his religious views very early on (if he ever really had them, other than for conforming to familial expectations), and after leaving the Navy he was deeply involved in Upton Sinclair’s EPIC movement.

His belief in world government must have been hard to sustain, given that he had a great deal of experience of the political process, both in Kansas City during the Pendergast years, and in California with EPIC. Corruption, dirty dealing, and backroom bargaining were the way things got done, and it would be hard to believe that things would be better with a single world-wide government.

What seems to have gotten him involved in EPIC was his first-hand experience of poverty and seeing the plight of the “Okies” who’d come to California after the dust bowl wiped out so many farms in the central states. There were not enough jobs for them, even displacing the Mexican migrant labourers, and they were ineligible for state assistance until after they’d been in California for a year. Sinclair appeared to be the only politician with any plan other than oppressing the Okies enough to force them to move on.

Practically speaking, the end is in sight for passwords

Advances in computing are not always uniformly beneficial: short passwords are increasingly vulnerable to brute-force cracking:

The availability of password-cracking tools based on increasingly powerful graphics processors means that even carefully chosen short passwords are liable to crack under a brute-force attack.

A password of less than seven characters will soon be “hopelessly inadequate” even if it contains symbols as well as alphanumerical characters, according to computer scientists at the Georgia Tech Research Institute. The security researchers recommend passwords at least 12 characters long.

The number crunching abilities of graphics processors were recently applied to commercial password auditing and recovery tools from Russian developer ElcomSoft. It’s a safe assumption that black hats are able to use the same type of technology for less laudable purposes. Richard Boyd, of the Georgia Tech Research Institute, told the BBC that the number-crunching capacity of graphics cards compares to those of supercomputers built only 10 years ago.

Passwords are going to go away, sooner rather than later. All of us have too many passwords to remember that it’s pretty much guaranteed that you’re using one of the following coping strategies:

  • Using the same password on many different sites (or, shudder, all of them)
  • Using a simple password (among the most commonly used are “password” and “letmein”)
  • Leaving a sticky note on your monitor or your keyboard with your passwords listed
  • Using the name of the site as your password for that site

There are tools available to generate passwords that avoid the most obvious pitfalls (too short, no numeric or non-alphanumeric characters, using full words), but very few people use them consistently. I don’t know what the replacement for passwords will be, but we clearly need to move to more secure ways of verifying identity as soon as we can.

I’ve posted items about password security before.
