This: Python Displacing R As The Programming Language For Data Science.

Recently, I've had a former colleague asking questions about Data Science. See Obstinate Idiocy They -- weirdly -- insisted that the only language that made sense to them was Excel.

My response was a blunt "What?"

The Python vs. R post …

The correct answer is: It Doesn't Matter. In spite of this. (A) The question gets asked. And worse. (B) It gets answered. And people take their answers seriously. As if there are Profound Differences among programming languages. Among Turing Complete programming languages there are few Profound Differences. The pragmatic differences …

I upgraded to Mac OS X 10.9 "Mavericks" today.

Python 3.2.4 crashed in odd places. Not all the time. But help() stopped working to give one example.

I upgraded to Python 3.3 (it's about time to do that, anyway.)

It crashed, also. Similar places.

Here's the …

Code Rot is Real. It Leads to Subtle and Expensive Bugs.

Claiming that code cleanup is just pointless "gold plating" is the kind of thing that can drive a company out of business.

I've revised PyLit to work with Python3. See https://github.com/slott56/PyLit-3 The code seems to pass all the unit tests. The changes include Python3 revisions, plus a small change to handle trailing spaces in a sightly cleaner fashion. This was necessary because I have most of my editors …

Even though I wrote a literate programming tool (PyWeb) I slowly came to realize that it's not very good.

Mostly, I followed the Web/Weave world view and cribbed their markup syntax. It's not bad, but, the PyWeb markup is based on some presumptions about literate programming that were, perhaps …

That was challenging.

I rewrote almost all of my Introduction to Programming book into an iBook. Trimmed it down. Refocused it. Changed from Python 2.6 to 3.2. A complete refactoring from which almost nothing of the original book survives except the goals.

Look for it October 1st in …

Once upon a time, Apple offered iBlog. Then they switched to iWeb. Then they abandoned that market entirely.

That leaves some of us with content in iBlog as well as iWeb. Content we'd like to work with without doing extensive cutting and pasting. Or downloading from a web server. After …

First, and most important, Omni Outliner is a super-flexible tool. Crazy levels of flexibility. It's very much a generic-all-singing-all-dancing information management tool.

It has a broad spectrum of file export alternative formats. Most of which are fine for import into some kind of word processor.

But what if the data …
