Why is the Win32 API so separated from the C runtime (e.g. kernel32.dll provides ZeroMemory instead of memset)? Is it because Pascal's popularity early on meant that Microsoft didn't want to tie early versions of Windows to C?

people sometimes ask me "julia, have you ever written a comic about X?". I have a search page where you can search (almost) all my comics: wizardzines.com/comics it's just by title, not full text search yet

Facebook is down this morning, apparently due to a BGP problem. What's BGP? It's an absolutely essential but fairly obscure internet protocol. I have a CS degree, but I only know about it because I did a summer internship with @Akamai a very long time ago. A brief explainer:

Handy pattern I enjoy: Clone the repo twice. This way, I can have two local copies, pointed to different branches. I find this is useful when I need to reference or review code in a different branch. I don't have to commit/stash my work-in-progress to do so. 😎

Any good books or articles on Hashicorp Vault? I'm specifically looking for how things get boot strapped in a deployment. How to automatically unlock in a secure manner? I have a chicken and egg feeling.


This is called being coachable, and it's highly linked to long term improvement and success.

The ability to take negative feedback (including the ability to hear "no") is a real superpower. Something that took me a while to learn: this is a skill that you can work on!!



I almost never use booleans as return values as there are almost always more that 2 states.

A very common programming practice is replacing booleans with something more informative, like a enumeration or a nullable timestamp. We do this for different reasons: in the former case b/c our problem doesn't map neatly to true/false, the latter case for enriched metadata.



Any good books in low level SSL?


Serious question, is there a single meaning of "open" port? I can see at least 2 meanings: open via firewall (or lack of firewall), and having a service bound to it.

Is having all ports open to a server a security vulnerability?
