Göttingen Göttingen ist “ein arges Loch, aus dem man, wenn man erst mal drin ist, nur schwer wieder rauskommt”, so angeblich Georg Christoph Lichtenberg (1742 - 1799) [Gert Hofmann: “Die kleine Stechardin”]. Vielleicht gibt's in der Mensa ja mal Saubohnen mit Schweinebauch.

Made in USA Paul Graham describing the impression of the USA. He says they are good at making software, because it is a chaotic process, but this is exactly why they are not good at making software at all: They think it should be a chaotic process, but this type of prototyping is not enough. What he does not say is, that good software always needs a planning phase. And for all examples he enlists, there is a planning phase, even for Visicalc, though it may not be visible on the first glance. Good software is planned first, then implemented, where implementation includes prototyping and careful changing the plan where necessary, of course.

Burrows/Wheeler a PDF copy of the original paper (postscript) describing their block sorting compression algorithm. Another short description is given by Mark Nelson.
Edsger W. Dijkstra thank-worth insisted on programming in a structered way, though he was wrongly quoted, he never stated the Goto Statement Considered Harmful. In fact, the original title is A Case against the GO TO Statement, which includes this quotation:
For a number of years I have been familiar with the observation that the quality of programmers is a decreasing function of the density of go to statements in the programs they produce.
Quotations from How do we tell truths that might hurt?:
The use of COBOL cripples the mind; its teaching should, therefore, be regarded as a criminal offence.
Quotations from Essays on the nature and role of mathematical elegance:
For reliability simplicity is an absolute prerequisite.
Quotations from the Humble Programmer:
The competent programmer is fully aware of the strictly limited size of his own skull; therefore he approaches the programming task in full humility, and among other things he avoids clever tricks like the plague.
Today a usual technique is to make a program and then to test it. But: program testing can be a very effective way to show the presence of bugs, but it is hopelessly inadequate for showing their absence.
Niklaus Wirth invented a series of nice toys. I never had the impression, Pascal might be a mess, until finally I tried to write a syntactic and semantic specification for it as part of the Mother Generic Compiler project. And yet, UCSD Pascal and the P-System have been really useful at their times.
