The quest for a better UIAlertView

By Marc, on June 9th, 2010%

One of the things that has annoyed me while developing my iPhone game “Wordly” are dialogs that appear modal to the user, but are non-blocking from the programmer perspective. For example, let’s take UIAlertView.

You tell a UIAlertView to show itself and the user sees a modal dialog, but the code after your show message keeps executing, . . . → Read More: The quest for a better UIAlertView

By Marc, on October 24th, 2008%

As you all probably know, I’ve written a word game for the iPhone called Word Up!

Tonight, I started getting an error while trying to run my app from Xcode on my device (provisioned for development). The error was:

Your mobile device has encountered an unexpected error (0xE8000001)

Python ternary operator

By Marc, on May 18th, 2008%

Today’s Python discovery:

Python doesn’t have the C style ?: ternary operator (e.g.: cond ? valueIfTrue : valueIfFalse).

But as of Python 2.5 it has a ternary operator with its own syntax: value_when_true if condition else value_when_false

For example:

>>> ‘a’ if 1 == 1 else ‘b’
‘a’
>>> ‘a’ if 1 == 0 else ‘b’
‘b’

This is actually clearer and more Pythonic . . . → Read More: Python ternary operator

Setuid demystified

By Marc, on February 1st, 2008%

Interesting that the Unix calls for setting user ids of processes are so varied and so complex, that they warranted an entire paper. I only skimmed, but I did get a pretty good description of the “saved uid” parameter of the setresuid call.

TiVo HME SDK for Python

By Marc, on January 30th, 2008%

Just stumbled up on this (via TiVoBlog who in turn found it via TiVo Lovers) and will have to give it a try sometime:

From TiVo HME SDK for Python:

An implementation of TiVo’s HME (Home Media Extensions) protocol for Python, as a module (hme.py), a simple server (hmeserver.py), and examples (mostly ported from TiVo’s Java HME SDK). . . . → Read More: TiVo HME SDK for Python

Perl->{‘5.10′} += (“//” && > Operator[s])? =~ /amusing/

By Marc, on December 28th, 2007%

A snippet from the latest freshmeat.net announcement of Perl 5.10 that landed in my email inbox:

This version includes a new smart match operator, a switch statement,
the // defined-or operator, regular expression improvements, and
other language changes…

Funny, I was just thinking that what Perl needs most is more operators… . . . → Read More: Perl->{‘5.10′} += (“//” && > Operator[s])? =~ /amusing/
