Race condition in UE4
When multiple actors are placed in the world, their beginplay() execution order are unpredictable. Gotta find a way to avoid race condition especially when one actor depends on another. Can use a simple delay node or put the initialization code to construction script. The goal here is to ensure that when an actor tries to read the data from another actor, that data has already been initialized.
Another interesting observation is that it seems like the latterly compiled actor will also execute latterly, as if there is a queue that stores all the actors in the world, and once an actor gets updated, it gets moved to the end of the queue. But these are all my assumptions :)
Life is hard enough without having to worry about another race condition.
How to change symlinks atomically, Tom Moertel (2005)
Hey Jeff, the api key stuff in the RSS feed appears to be broken, and no one is responding on the bug reporting forum. Help!
Not sure what you’re talking about and I just looked over the bug reporting forum.
If you’re talking about podcasts and you’re a pocket casts user, there appears to be something with a recent update to pocket casts that breaks its ability to access the premium feeds. Not sure what the deal is there, that change is probably something they’d need to do on their end.
Jeff, why are there only ~8 companies that advertise on all podcasts (not just GB podcasts I mean)? I don't need a mattress, food box, underwear or a website; and the repetition is starting to grate.
I think we might have a brand-new advertiser next week!

Hey Jeff, I've got a favour/suggestion: could you guys put metadata/tags on your videos for download? I watch most GB stuff through Plex and it would be a bit nicer if the metadata were populated. Thanks, bye!
This would be cool, but making those changes to our encoding/uploading process isn’t trivial. It’d basically be a full overhaul to make sure the video robot is looking for and getting that data from our CMS.
Apache has a feature that will apply "Server Side Includes" (SSI) in served pages
This feature can be abused to run shell commands, in this example:
#<!--#printenv -->
Apache 2.3.8 and earlier will not apply SSI logic to an uploaded .htaccess file, but they will apply it to a .htaccess file
The author here exploits a filename/content-type issue in something called PaperClip to upload .htaccess and .htaccess
He exploits a concurrency issue to make the file persistent on the victim server
