You can vectorize the class’s __init__ function: import numpy as np class Site: def __init__(self, a): self.a = a def set_a(self, new_a): self.a = new_a vSite = np.vectorize(Site) init_arry = np.arange(9).reshape((3,3)) lattice = np.empty((3,3), dtype=object) lattice[:,:] = vSite(init_arry) This may look cleaner but has no performance advantage over your looping solution. The list comprehension answers … Read more
I write code for FPGAs, not ASICS… but TDD is my still my preferred approach. I like to have a full suite of tests for all the functional code I write, and I try (not always successfully) to write testcode first. Staring at waveforms always happens at some point when you’re debugging, but it’s not … Read more
This is similar to issues with trying to find a global minimum, where it’s easy to get stuck in a local minimum. Consider trying to find the global minimum for the profile below: you place the ball in different places and follow it as it rolls down the hill to the minimum, but depending on … Read more
Unfortunately, there is no good way to simulate a low-battery environment. You actually will most likely need to physically charge your device’s battery until it is just above the “low battery” state and then debug your application. To address what others have said: There is no way to simulate low battery notifications. The project that … Read more
My favoured technique: signal clk : std_logic := ‘0’; — make sure you initialise! … clk <= not clk after half_period; I usually extend this with a finished signal to allow me to stop the clock: clk <= not clk after half_period when finished /= ‘1’ else ‘0’; If you use a std_logic item for … Read more
EDIT 2023-02-02: The answer below was written in 2016. While it should still work, you can probably achieve this in a more straightforward manner by using test clocks instead. In order to test failed subscription payments, you can do something like this: Create the customer with a card token for a valid card (e.g. 4242 … Read more
When running in debug mode you can use the little arrow button in the debug area (Shift+Cmd+Y) in Xcode to specify a location. There are some presets or you can also add a GPX file. You can generate GPX files here manually: http://www.bikehike.co.uk/mapview.php (from answer: https://stackoverflow.com/a/17478860/881197)

Features: GPL license. Winpdb is Free Software. Compatible with CPython 2.3 through 2.6 … Read more
You can simulate the iPhone user agent in Safari 5 if you set up the Developers menu item in Preferences>Advanced. The webkit engine in Safari 5 is similar to iPhone’s browser so most of the HTML 5 stuff works the same. As a bonus the Developer’s tab allows you to debug JavaScript and some CSS … Read more
In your AVD advanced settings, you should be able to set front and back cameras to Webcam() or Emulated.
