Meeting Tonight! 2015-01-21

Location – Gordmans Office Building in Aksarben thanks to Aaron Keck.

Meeting starts at 6pm, Wednesday, 1/21/15

Parking and entry details:

The building is the northwest corner of 67th and Frances and the Gordmans entrance is next to the “g” sign, about midway along the East side of the building. There’s parking directly out front, but it sometimes fills up in the evenings. The garage around back is open to the public after 5:30 or 6 as well.

The building doors lock at 5, so Aaron will be standing by to badge people in starting around 5:45. If you’re running late, or early, just shoot him or the list an email.

Raspian: Configuring for editing Python with vim

Friday April 1st, 2016 04:56:32 AM JeffH
We have a new Raspberry Pi 3 in the house and I’ve been having some fun getting it setup to edit Python with customized vim. You can see my dotfiles here. So in a nutshell, I like using tmux + vim + plugins and customizations. The following are some snags I ran into and how [...]

Birthdays, Ramanujan but in the end it’s just Python.

It’s Sunday morning and I get some time to myself, so I’m listening to some blues and catching up on my newsfeeds when I come across this interesting article on calculating what size group of people would be necessary to have a 50/50 chance of two of them sharing the same birthday. General birthday problem [...]

<selenium.webdriver.remote.webelement.WebElement object at 0x874b22c>
>>> sbx = b.find_element_by_name('q')

Omaha Python Users Group Meeting, June 20, 2011

Tonight’s Meeting:

Joe talked about the 2 semester course he attended at Iowa Western on Linux Engineering.

Steve talked about Code Like a Pythonista, by David Goodger.  He thinks it is a great resource.  I agree with him. (So much I did a presentation on David’s material back in 2008).  Steve also liked the Python Challenge.  He has made it though the first 5 or 6 so far and hopes to make it all the way through.

Joe brought up the fact that Full Circle Magazine – has released two specific Python issues, Issue 1 and Issue 2.

Jeff brought a Code editor that he likes, Editra.  It is a very nice, rapidly advancing development environment.  If you are in the market you should take a look if Komodo or PyCharm are turning your head.

A non-python, learn how to program environment is MIT’s Scratch.  Joe likes Snake Wrangling for Kids.
