Folks like to claim that unit testing absolutely requires each class be tested in isolation using mocks for all dependencies. This is a noble aspiration, but doesn't work out perfectly well in Python.

First, "unit" is intentionally vague. It could be a class, a function, a module or a package …

web2py wins an award -- cool. I really like Django. But...

"Are you implying that a scalable Data Warehouse solution could be implemented using Python and serialised files?"

Not "implying". I'm trying to state it as clearly as I can. A scalable data warehouse solution involves a lot of flat file processing.

ETL, for example, is mostly a flat-file pipeline. It …

We process a fair amount of externally-prepared datasets. 40,000 rows of econometric data that we purchased from a third-party. Mostly, the data is in a usable format: .CSV or .XSLX.

Once in a while, we get CSV with |. A few times, we got fixed-format COBOL-style records.

Recently, we got …

Check out this question on Stack Overflow: "Python: replace a string by a float in txt file".

The question is confusing, but it appears to be a longish and confused description of simple formatting or template substitution. It's hard to be sure, but it sounds like one of Those Things …

Someone sent me this: "“Building Skills in Python” – Steven F. Lott".

I had a vague idea that this book would get some traction. This response was surprising. I guess I should get to work on the upgrades.

And focus on the "no-nonsense" comment.

During chapter technical reviews, the question of technical depth has come up time and again. Essentially, in every single chapter. In the older Building Skills in Python book, there are a number of topics that feel "digressive" to the reviewer and editor. Too much depth.

However, there are a number …

Just started learning about "Hackerspace". Without really knowing what I was doing, I fell into the 757 Labs Hackerspace. The 757 Python Users' Group, specifically. What a great idea. Bright people. Interested in the same area of technology. It's like hanging around with sailors at a marina.

Tonight (May 25th). Red Dog. Colley Ave. Ghent. I'll be wearing my Stack Overflow shirt. I'll be there about 7. I know that at least one other person won't be there until 8.

The Meetup link.

I like this meetup idea a lot. Probably because the WFH life-style is a …

I'm looking forward to meeting other Python developers in Hampton Roads.

Tonight. 7:00 PM. See you there.
