Journal Journal: bamboo better than carbon fiber for most things

There have been a number of stories about both carbon fibre and bamboo in the news recently.

So this is a post I originally made as AC, about why CF is usually a poor choice:
The real problem with 'wonder materials' is designers often do

A summary of the changes is here :

Changes so far to OpenSSL 1.0.1g since the 11th include:

  • Splitting up libcrypto and libssl build directories
  • Fixing a use-after-free bug
  • Removal of ancient MacOS, Netware, OS/2, VMS and Windows build junk
  • Removal of “bugs” directory, benchmarks, INSTALL files, and shared library goo for lame platforms
  • Removal of most (all?) backend engines, some of which didn’t even have appropriate licensing
  • Ripping out some windows-specific cruft
  • Removal of various wrappers for things like sockets, snprintf, opendir, etc. to actually expose real return values
  • KNF of most C files
  • Removal of weak entropy additions
  • Removal of all heartbeat functionality which resulted in Heartbleed

Do not feed RSA private key information to the random subsystem as entropy. It might be fed to a pluggable random subsystem.... What were they thinking?!

So far as all the "won't this introduce more bugs than it fixes" comments go, this is a recurring argument I have at work. I am of the "clean as you go", "refactor now" school.
Everyone else says "If it works don't fix it"(IIWDFI), "don't rock the boat" etc.
Heartbleed is what happens when the IIWDFI attitude wins. Bugs lurk under layers of cruft, simple changes become nightmares of wading through a lava flow of wrappers around hacks around bodges.
Whenever anyone says IIWDFI, remind them that testing can only find a small proportion of possible bugs, so if you can't see whether it has bugs or not by reading the code, then no matter how many test cases it passes, it DOESN'T WORK.

Yes, it appears young people are becoming more impatient shallow, and frivolous, and have been for some time:

The young people of today think of nothing but themselves. They have no reverence for parents or old age. They are impatient of all restraint. They talk as if they knew everything, and what passes for wisdom with us is foolishness with them.

- Peter the Hermit, 13th Century AD

I see no hope for the future of our people if they are dependent on frivolous youth of today, for certainly all youth are reckless beyond words... the present youth are exceedingly impatient of restraint

-Hesiod, 8th century BC

The art of letter-writing is fast dying out. When a letter cost nine pence, it seemed but fair to try to make it worth nine pence ... Now, however, we think we are too busy for such old-fashioned correspondence. We fire off a multitude of rapid and short notes, instead of sitting down to have a good talk over a real sheet of paper.

- The Sunday Magazine 1871

It is, unfortunately, one of the chief characteristics of modern business to be always in a hurry. In olden times it was different.

- The Medical Record 1884

With the advent of cheap newspapers and superior means of locomotion... The dreamy quiet old days are over... For men now live think and work at express speed. They have their Mercury or Post laid on their breakfast table in the early morning, and if they are too hurried to snatch from it the news during that meal, they carry it off, to be sulkily read as they travel ... leaving them no time to talk with the friend who may share the compartment with them... The hurry and bustle of modern life ... lacks the quiet and repose of the period when our forefathers, the day's work done, took their ease...

- William Smith, Morley: Ancient and Modern, 1886

Conversation is said to be a lost art ... Good talk presupposes leisure, both for preparation and enjoyment. The age of leisure is dead, and the art of conversation is dying.

- Frank Leslie's popular Monthly, Volume 29 1890

Intellectual laziness and the hurry of the age have produced a craving for literary nips. The torpid brain ... has grown too weak for sustained thought. There never was an age in which so many people were able to write badly.

- Israel Zangwill, The Bachelors' Club 1891

The art of pure line engraving is dying out. We live at too fast a rate to allow for the preparation of such plates as our fathers appreciated. If a picture catches the public fancy, the public must have an etched or a photogravured copy of it within a month or two of its appearance, the days when engravers were wont to spend two or three years over a single plate are for ever gone.

- Journal of the Institute of Jamaica, Volume 1 1892

So much is exhibited to the eye that nothing is left to the imagination. It sometimes seems almost possible that the modern world might be choked by its own riches, and human faculty dwindle away amid the million inventions that have been introduced to render its exercise unnecessary. The articles in the Quarterlies extend to thirty or more pages, but thirty pages is now too much so we witness a further condensing process and, we have the Fortnightly and the Contemporary which reduce thirty pages to fifteen pages so that you may read a larger number of articles in a shorter time and in a shorter form. As if this last condensing process were not enough the condensed articles of these periodicals are further condensed by the daily papers, which will give you a summary of the summary of all that has been written about everything. Those who are dipping into so many subjects and gathering information in a summary and superficial form lose the habit of settling down to great works. Ephemeral literature is driving out the great classics of the present and the past ... hurried reading can never be good reading.

- G. J. Goschen, First Annual Address to the Students, Toynbee Hall. London 1894

The existence of mental and nervous degeneration among a growing class of people, especially in large cities, is an obvious phenomenon ... the mania for stimulants ... diseases of the mind are almost as numerous as the diseases of the body... This intellectual condition is characterized by a brain incapable of normal working ... in a large measure due to the hurry and excitement of modern life, with its facilities for rapid locomotion and almost instantaneous communication between remote points of the globe...

- The Churchman, Volume 71 1895

The cause of the ... increase in nervous disease is increased demand made by the conditions of modern life upon the brain. Everything is done in a hurry. We talk across a continent, telegraph across an ocean, take a trip to Chicago for an hour's talk... We take even our pleasures sadly and make a task of our play ... what wonder if the pressure is almost more than our nerves can bear.

- G. Shrady (from P.C. Knapp) "Are nervous diseases increasing?" Medical Record 1896

To take sufficient time for our meals seems frequently impossible on account of the demands on our time made by our business... We act on the apparent belief that all of our business is so pressing that we must jump on the quickest car home, eat our dinner in the most hurried way, make the closest connection for a car returning ...

- Louis John Rettger. Studies in Advanced Physiology 1898

In these days of increasing rapid artificial locomotion, may I be permitted to say a word in favour of a very worthy and valuable old friend of mine, Mr. Long Walk? I am afraid that this good gentleman is in danger of getting neglected, if not forgotten. We live in days of water trips and land trips, excursions by sea, road and rail-bicycles and tricycles, tram cars and motor cars .... but in my humble opinion, good honest walking exercise for health beats all other kinds of locomotion into a cocked hat.

T. Thatcher, "A plea for a long walk", The Publishers Circular 1902

The art of conversation is almost a lost one. People talk as they ride bicycles–at a rush–without pausing to consider their surroundings ... what has been generally understood as cultured society is rapidly deteriorating into baseness and voluntary ignorance. The profession of letters is so little understood, and so far from being seriously appreciated, that ... Newspapers are full, not of thoughtful honestly expressed public opinion on the affairs of the nation, but of vapid personalities interesting to none save gossips and busy bodies.

- Marie Corelli, Free opinions, freely expressed 1905

We write millions more letters than did our grandfathers, but the increase in volume has brought with it an automatic artificial machine-like ring ... an examination of a file of old letters reveals not only a remarkable grasp of details. But a fitness and courtliness too often totally lacking in the mechanical curt cut and dried letters of to-day.

- Forrest Crissey, Handbook of Modern Business Correspondence 1908

A hundred years ago it took so long and cost so much to send a letter that it seemed worth while to put some time and thought into writing it. Now the quickness and the cheapness of the post seem to justify the feeling that a brief letter to-day may be followed by another next week–a "line" now by another to-morrow.

- Percy Holmes Boynton, Principles of Composition 1915 or perhaps its just that people like to complain about how the young of today can't think like they could in 'our days'. As Ovid said:

Let others praise ancient times; I am glad I was born in these.
