Ask HN: What are good CS journals that publish source code with papers?

What are some good computer science research journals that actually publish source code with their papers? I would like to causally read research papers (most likely involving image processing, video encoders etc) and follow along in the source code to better understand how to implement DSP algorithms etc. Any ideas? I may get into major journals through my school (just need help narrowing down which ones publish source code) and i am willing to purchase a subscription to good ones.
