Grumpy - Go running Python! #compilers

Wed, 04 Jan 2017 17:28:00 +0000

Google runs millions of lines of Python code. The front-end server that drives youtube.com and YouTube’s APIs is primarily written in Python, and it serves millions of requests per second! YouTube’s front-end runs on CPython 2.7, so we’ve put a ton of work into improving the runtime and adapting our application to work optimally within it. These efforts have borne a lot of fruit over the years, but we always run up against the same issue: it's very difficult to make concurrent workloads perform well on CPython. 23 points posted by kenny

Key pinning in Go #crypto

Thu, 22 Sep 2016 12:31:00 +0000

Key pinning is a technique that can protect clients from rogue or compromised certificate authorities. If you have control over the client and the server, you can bake the server's public key into the client and bypass (or supplement) trust in certificate authorities. 14 points posted by gopher

Introducing vice - go channels across many machines #concurrency #goroutines

Fri, 28 Jul 2017 14:28:00 +0000

Concurrency is a great way to get more stuff done faster. Go channels are perfect for enabling multiple concurrent goroutines to safely communicate within a single process, but if we want to let multiple machines/nodes communicate in a similar way, we have to write completely different code and integrate with messaging queues, gRPC, or something else. Until now.

Practice Go: Calculate the Jaro distance #challenge #practicego

Fri, 03 Mar 2017 08:56:00 +0000

The Jaro distance is a measure of similarity between two strings. The higher the Jaro distance for two strings is, the more similar the strings are. The score is normalized such that 0 equates to no similarity and 1 is an exact match. 13 points posted by kenny

Video: The hidden micro-service - caching with Go at Netflix #data #caching

Fri, 20 Jan 2017 13:24:00 +0000

Netflix is well known for championing the microservice model, but within the complex layers of dependencies is a hidden service: the caching layer. The Netflix customer experience relies heavily on caches to provide a high-volume, low latency, globally available data layer that backs our stateless services. Throughout a typical customer experience, from sitting down on the couch through playing a movie, caches play a role in every interaction. The use cases here range from session storage to video history to subscriber status, all of which benefit from the stability and fault tolerance of EVCache, the primary caching system in use at Netflix. 12 points posted by kenny

Go is an open source language that enables the production of simple, efficient, and reliable software at scale. Designed by Google for cloud workloads, Docker, Kubernetes, Istio, and gVisor are all implemented in Go. With great built-in concurrency (ideal for cloud services), a best-in-class networking stack, and excellent tools for developers & operators it’s become one of the fastest growing & most loved languages. Meet the minds behind the Go language and participate in our interactive panel.

Wed, 01 Feb 2017 14:28:00 +0000

A talk by Damian Gryski at DotGo 2016. Modern computers have multiple layers of caches between the processor and main memory. Algorithms which effectively use these caches can be orders of magnitude faster than those that don’t. Damian looks at how using slices can make your inner loops more cache friendly. 11 points posted by kenny

A Brief Tour of Practical Crypto in Go #cryptography

Sat, 16 Dec 2017 21:25:00 +0000

Go offers a rich collection of packages supporting cryptographic operations. From a beginner’s perspective, maybe too many offerings! I offer up an overview of what’s available and an introduction to some practical uses of cryptography in Go. Implementation details are always critical when discussing crypto. We’ll discuss some general implications of making poor choices and how such choices can completely undermine any uses of these tools. 10 points posted by andythomas

Neugram - a scripting language integrated with Go #cli #scripting #neugram

Sun, 29 Oct 2017 18:19:00 +0000

I started working on Neugram because as I spent more time programming in Go I found myself writing a larger fraction of the scripts better suited to Python or Perl in Go. My daily programming came to be dominated by bash and Go.

The problem is, bash is an awkward language for a ~100 line program, and sometimes so is Go. While it is thoroughly enjoyable to use the same standard library in scripts as in big complex projects, Go is slower to work in than Python and Perl for a few reasons:
