Tradition

Anybody who's seen Fiddler On The Roof knows that Judaism is all about Tradition.

Why should that be?

Making tradition so central (and not just a particular tradition, but the institution of tradition itself), emphasizes the notion of the Jewish People as an entity, an organism.

Just as a person grows throughout his life, and interacts with his environment, so too, we are to imagine the Jewish People moving through history.

Exceptions

There are three broad categories of exceptions that should be handled:
  • Contract not met by client (either code or supporting configuration)
  • Resource not available
  • Programming error in provider code
Three are three broad ways to handle them:
  • Try to fix it
    • Reset state
    • Address the issue specified by the exception
  • Just do without the functionality
  • Present the error
    • Log it
    • Report to the user
General rules of exceptions:
  • Throw early
  • Catch late
  • Handle exactly once
  • New exceptions are for new ways of handling
  • Use "finally" to do cleanup
  • Don't throw in constructors

If an exception can't be handled differently based on its type, you shouldn't create a new exception class for it.

With java 1.4 exception wrapping, there's no need to have separate exception classes for separate components.

Inspired by O'Reilly's Best Practices for Exception Handling.

Better Programmers' Editor

Programmers' editors should format as you type. Modern editors do this for hiliting, but they should also do it for spacing. For example, if you type:
    while(true){i+=1;}

the editor should immediately display:
    while (true) {

i += 1;
}
Cursor movement should also ignore that whitespace. (If the cursor is before the "i" above, pressing the left arrow should move the cursor to before the "{".)

Of course, the editor should also wrap long lines as you type.

This behavior is described in Displaying and Editing Source Code in Software Engineering Environments, but I haven't seen an implementation.

Just found Harmonia, which looks like it does it. An eclipse plugin is in the works.

What Politicians Don't Talk About

While watching the presidential debates, it occurred to me that there's a lot of relevant stuff that politicians all know, but don't talk about.

For example, I don't think anyone disputes that a strong motivation for invading Iraq was fear of unfriendly power over America's interests, namely its interest in cheap oil. (Why not Libya?) Presumably there's a good political reason why Kerry also doesn't mention this.

It goes the other way too; much of what politicians talk about is completely irrelevant.

Besides being highly cynical, what's wrong with this state of affairs? It insulates much of the electorate from political reality, but you could argue that everyone would be almost as insulated anyway.

Are the members of one political party disproportionately guilty of this disingenuousness?

Spaces vs. Tabs

How should programs be indented, with tabs or with spaces?

This is not a question of whether the programmer hits the Tab key or the space bar on the keyboard. It's a question of what actually goes in the file, and what happens when people want to use different numbers of spaces to display indentation levels. Literal Tab characters are referred to as "hard tabs", and sequences of Space characters are referred to as "soft tabs".

(Almost) everyone agrees that a single file should use only one or the other for indentation. Mixing hard and soft tabs has more problems than either of the other two pure approaches, and causes confusion.

This is a religious war, but both approaches have their advantages:

Advantages of Soft Tabs
  1. columns may be arbitrarily aligned
  2. xterm copying doesn't need special handling
Advantages of Hard Tabs
  1. backspace and navigation work nicely
  2. number of displayed spaces is customizable
  3. indentation semantic is represented directly, and already standard
  4. makefiles don't need special handling

Arbitrary Alignments using Hard Tabs

With hard tabs, you can't portably line up your comments or constants like this:
doSomething();                             # this is a silly block of code,
doSomethingElseWithAMuchLongerStatement(); # which has a multi-line comment,
# which extends past the code itself

All but the third line could easily be solved by using spaces for tabs that occur after non-whitepace on each line. Some refer to this as a third camp "use tabs for indentation and spaces for alignment", and others reduce it to "use tabs for indentation and eschew alignment".

Hard tabbing also requires:
mylist = [
1,
2,
3
]
instead of
mylist = [ 1,
2,
3
]

Xterm Clipboard using Hard Tabs

Copying from an xterm converts hard tabs to soft tabs, so you have to configure your editor to convert them back.

Navigation using Soft Tabs

Just like a single keystroke creates an indentation level, a single keystroke should move the cursor over an indentation level. Modern editors allow you to back up an indentation level using the Backspace key, but don't yet allow you to navigate indentation levels using the arrow keys.

Customizing the Number of Displayed Spaces using Soft Tabs

Though it's certainly possible to munge source code in order to customize the tabstop, it's a little risky. Tools for some languages (perl) don't make any guarantees that it can be done reliably. Even if you can do it reliably, you'll have to hack it, and if you also make modifications you'll probably cause bogus diff history.

Makefiles using Soft Tabs

The configuration files used by the make tool require hard tabs, so your editor has to handle this.

Semantics

There is some beauty in representing the semantic unit with a single character, and without extraneous formatting information (sort of like "\n" instead of "\r\n"). Maybe as editors get better at nicely formatting source code, soft tabs will become less attractive.

Editor Configuration

vim for soft tabbers: set expandtab | set smarttab

and shiftwidth should be set to configure the number of spaces to use for indentation; tabstop will be only be consulted for tabs not occurring at the beginning of the line. In order to handle makefiles, use: au FileType make setlocal noexpandtab

vim for hard tabbers: set noexpandtab

or maybe use a script to expand tabs later in the line

Platform Proliferation

Along the lines of the previous post, I hate platform proliferation. Even using the same programming language, code must be rewritten for each platform.

Windows and Mac each have a couple of platforms, as do the free desktops projects (Gnome and KDE), the major cross platform applications (Mozilla and OpenOffice), and most modern "languages" (e.g. Java, Python, OCaml).

People love the UNIX interface, in which everything is a file, and a file is a stream of bytes which may have a hierarchical name. That interface now appears to be insufficiently rich, but it's powerful exactly because it's so simple.

Maybe there's a new interface which is comparably simple, but can do 80% of what we want for components? Some examples of difficult modules to support are: graphical user interface, spell-checking, auto-completion, clipboard and search and undo, linking and embedding documents.

At the Desktop Developer Conference, Havoc Pennington talked about fragmentation of platforms.

One True Language

Techies often insist that it's good that there're many different programming languages, because each language has its strengths. They say that language design is all about making compromises, and that the compromises chosen for each is best for a particular problem domain.

This is a big mistake. For most applications, the benefit of using a specific language is minimal. The cost, however, of having code written in many different languages is huge. Code written in different languages is difficult to re-use. It's difficult to integrate. It's difficult to learn and support. In short, the language that code is written in is its single biggest dependency, and we are increasing and fracturing dependencies for no good reason. For a recent project at work, I had to write in several different languages: Java, Perl, Csh, SQL / Sybase stored proc language, XML, and a proprietary "Job Information Language". A single language could satisfactorily perform the jobs of all, and it would only need a single toolset.

Techies like the idea of a large language ecosystem because they love this stuff. They're attached to it, and want to see more of it. They love languages like shoemakers love shoes.

It almost doesn't matter what the one true language is, but of course I'm going to share some ideas about what I think it should look like.

The C programming language was an abstraction layer for making code portable. The next abstraction layer should make it as easy as possible to write and maintain code. All the other requirements are relatively insignificant.

So the language should be mostly procedural and object oriented. It should have automatic garbage collection. It should have built-in collection classes. It should be dynamically typed, but strongly typed.

The Zen of Python (by Tim Peters)

Beautiful is better than ugly.
Explicit is better than implicit.
Simple is better than complex.
Complex is better than complicated.
Flat is better than nested.
Sparse is better than dense.
Readability counts.
Special cases aren't special enough to break the rules.
Although practicality beats purity.
Errors should never pass silently.
Unless explicitly silenced.
In the face of ambiguity, refuse the temptation to guess.
There should be one-- and preferably only one --obvious way to do it.
Although that way may not be obvious at first unless you're Dutch.
Now is better than never.
Although never is often better than *right* now.
If the implementation is hard to explain, it's a bad idea.
If the implementation is easy to explain, it may be a good idea.
Namespaces are one honking great idea -- let's do more of those!

Property

When we talk about "intellectual property" (IP), we've already decided exactly how it should work. Calling it "property" makes us think we should treat it like a sandwich, though it's really more like the proverbial cake that you can eat, and have it too.

100 years ago, when you bought a book, you owned that book. You could do anything you wanted with your copy of that book except make a copy of it. The government gave publishers the right to prevent copying their books, in order to maximize the amount of publishing that would be done.

Now, when you buy a book, you haven't bought anything. You've licensed that book. The publisher retains all the rights except for limited reading privileges.

This isn't yet completely true, but it is the way that everyone already thinks of it. The law considers every digital access to be a "copy", so every use is governed by copyright. "Click-wrap" and "shrink-wrap" allow publishers to easily dispense with traditional copyright, and invent any bizarre license conditions they please. This is only logical, since the publisher owns the work.

What's wrong with strict intellectual property? Shouldn't the market discourage unreasonable license terms, like restricting the right to read books aloud?

Well this market is inefficient. Publishers consolidate. Publishers are big, and consumers, in general, are small. This makes it difficult for consumers to negotiate. It's a shame that fair use will suffer, but there are two bigger problems with strong IP:
  • it's grossly inefficient
  • it could hamper the "prosumer revolution"

The internet makes it so easy to publish that potentially every consumer could become a producer of valuable creative work. Creative work is possible only by building on top of existing work. Clearing rights has become significantly more difficult than distribution. Most lawyers don't see anything wrong with increasing the need for lawyering in the world, but everyone else should recognize that the extra transaction costs are prohibitive.

It's hard to tell how inefficient our current system is, without real systems to compare it to. But it's equally hard to believe that authors are motivated by the potential revenues from their work 100 years from now. Less extreme cases are harder to judge.

With what should the intellectual property metaphor be replaced?

Many thinkers advocate "compulsory licensing", which requires everyone to pay a tax for funding new works. The proceeds from this tax would be divided up and awarded to authors based on the results of some sort of polling. It would be difficult to prevent gaming such a system. It would also be difficult to properly poll for derivative works. It would probably require administration to assign weightings to different types of work.

Alternatively, we could eliminate copyright law altogether, and have publishers just protect new content as best they can. This wouldn't be so different from today, except that content which is eventually freed would then be legal. Books would be the big loser in this scenario, because they are almost impossible to protect. Once comfortable reader devices are available, copying books will become rampant.
