Just a safety note for folks who use a lot of electricity. In the winter, you might have computers and space heaters. Or you might (like me) live "off the grid". We use an inverter with a transfer relay to switch between battery power and grid power. Recently, we had …

Just stumbled across several blog postings on unit test naming.

Essentially the TestCase will name the fixture. That's pretty easy to understand.

The cool part is this: each test method is a two-part clause: condition_"should"_result or "when"_condition_"then"_result.

For those of us who live mostly off the grid, with inconsistent WiFi through hosts that flake out frequently, Apple's AppStore download protocol is absolutely infuriating. It's the most brittle damn protocol I've ever seen. When there's any disruption, it simply discards the data it has and starts again. How …

An excellent exposition of secure salted password hashing.

This was really quite nice. It didn't have a Python version, but the clarity of the exposition makes the Python easy to write.

A few months back, I had this mystery conversation: {filename}/blog/2013/06/2013_06_27-password_encryption_short_answer_dont …

Finally upgraded to Python 3.3.3. The ordinary maintenance release fixed the problem with the previous release.

The previously documented patch ({filename}/blog/2013/10/2013_10_25-mac_os_x_109_mavericks_crashes_python_patch_available.rst) is no longer required.

Time to start incrementally installing all the various add-on components: docutils, PyYaml, Django, Jinja2, SQLAlchemy, etc.

Also, time …

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 …
