Reading Time: 3 minutes 5.5 Using the discriminator to improve data qualityAt this point, I started struggling with new programmatic ways to improve the dataset quality. New rule-based approaches had low precision, filtering out too many good emotes along with the bad. However, there was still a non-trivial proportion of low quality emotes, far too many to remove by…… Continue reading ThisEmoteDoesNotExist: Training a GAN for Twitch Emotes

Go memory ballast: How I learnt to stop worrying and love the heap
Reading Time: 11 minutes I’m a big fan of small code changes that can have large impact. This may seem like an obvious thing to state, but let me explain:These type of changes often involve diving into and understanding things one is not familiar with.Even with the most well factored code, there is a maintenance cost to each optimization…… Continue reading Go memory ballast: How I learnt to stop worrying and love the heap
How Twitch Addresses Scalability and Authentication
Reading Time: 3 minutes Curious how Twitch Identity services addresses scalability and performance challenges related to authentication?Last Tuesday, the Twitch Identity team — which helps Twitch users create and manage their digital identity and owns the services that provide authentication, authorization, and user metadata management — hosted a Meetup.com event to explain just that. But we’re recapping here just for you!First challenge: Login…… Continue reading How Twitch Addresses Scalability and Authentication

Skateboard Trucks Optimized for Downhill Racing with Metal 3D Printing
Reading Time: 3 minutes Engineering student Philipp Manger designed a pair of custom skateboard trucks for downhill racing — combining topological optimization and lattice structures — and had them 3D printed in metal. Downhill longboarding is an extreme sport combining skateboarding and surfing, capable of speeds of more than 90 miles per hour. Naturally, optimizing your gear for performance…… Continue reading Skateboard Trucks Optimized for Downhill Racing with Metal 3D Printing
Twirp: a sweet new RPC framework for Go
Reading Time: 4 minutes Why not gRPC?This code generation approach is not a novel idea at all. Google provides a framework, gRPC, which does a very similar thing, and gRPC has grown to be pretty prominent. In fact, we started out at Twitch using gRPC. It didn’t gain a lot of traction, though — we had some problems with it, and these…… Continue reading Twirp: a sweet new RPC framework for Go
Twitch invites you to take on the ICME 2018 Grand Challenge
Reading Time: 3 minutes Because of its scalability and low cost, HTTP streaming is now widely used for live broadcasting on the open Internet. A number of platforms including Twitch, Twitter, and Amazon Video are now providing live video services based on HLS or DASH for both user-generated content (UGC) and professionally-generated content (PGC).However, in comparison to more traditional…… Continue reading Twitch invites you to take on the ICME 2018 Grand Challenge
