I’ve been (re)reading the second edition of Rich Sutton’s Introduction to Reinforcement Learning, and I’ve decided to do the programming exercises. (Previously, I followed Fermat’s tradition of solving exercises on the margin.)
Exercise 2.5 is nice. It asks us to demonstrate the difficulties that …
Almost one year after following cs231n online and doing the assignments, I met the CIFAR-10 dataset again.
This time, instead of implementing my Convolutional Neural Network from scratch using numpy, I had to implement mine using TensorFlow, as part of one of the Deep Learning Nano Degree assignments.
As …
Had forgotten to post this here. Enjoy! (YouTube video.)
JupyterHub supports deployment behind a reverse proxy and even instructs how to do so behindnginx in its manual. I was unable to find documentation about how to do this serving the content from a reverse proxy subdirectory.
Since there’s been a long time since I worked as a sysadmin …
I just released version 0.2.0 of my process-shared reader-writer lock.
This release’s highlight is the awesome work did by Marcos Assunção to add support for Windows.
We also changed the API so that now you can use the lock by calling from
prwlock import RWLock instead of …
Recently I noticed some calls I was making to a certain C API were returning
pointers that I thought were invalid. A quick inspection with gdb confirmed
my fears. A particular interaction showed:
(gdb) print *job->someMember
Cannot access memory at address 0xec00000005
Unfortunately I don’t have access to …
Python lacks a lock type that supports multiple readers and a single
writer across multiple processes. Here we investigate how one can be
implemented using only default python features: ctypes and mmap,
and the POSIX reader-writer locks.
