What I Wish I Had Known Before Scaling Uber to 1000 Services
What I wish I had known before scaling Uber to 1000 services. Yup, even Uber had some issues with microservices - not all technical, some are political. The "use the best tool for the job" philosophy leads to a culture fragmented around languages. Monitoring, performance, debugging, logging, fanout, load testing, RPCs, all sort of problems pop up when using microservices.

Code Tools: JOL
JOL (Java Object Layout) is the tiny toolbox to analyze object layout schemes in JVMs. These tools are using Unsafe, JVMTI, and Serviceability Agent (SA) heavily to decoder the actual object layout, footprint, and references. This makes JOL much more accurate than other tools relying on heap dumps, specification assumptions, etc.

How I Reduced my DB Server Load by 80%
The author uses a series of performance tools (notably: scout, pg:outliers, papertrail) to find the cause of a nasty spike in DB load average; the culprit: a case-insensitive uniqueness validation performed rails-side that should have been implemented as an index DB-side. Although the toolchain is Heroku-centered, the techniques and lessons learned are applicable to our tech stack.

Terraform
Terraform is a tool for building, changing, and versioning infrastructure safely and efficiently. Terraform can manage existing and popular service providers as well as custom in-house solutions, kinda like what CloudFormation does for AWS.

Configuration files describe to Terraform the components needed to run a single application or your entire datacenter. Terraform generates an execution plan describing what it will do to reach the desired state, and then executes it to build the described infrastructure.

Terraform provides a flexible abstraction of resources and providers. This model allows for representing everything from physical hardware, virtual machines, and containers, to email and DNS providers.

CNTK: Computational Network Toolkit
Microsoft's Computational Network Toolkit (CNTK) is now on GitHub. CNTK, the Computational Network Toolkit by Microsoft Research, is a unified deep-learning toolkit that describes neural networks as a series of computational steps via a directed graph. In this directed graph, leaf nodes represent input values or network parameters, while other nodes represent matrix operations upon their inputs. CNTK allows to easily realize and combine popular model types such as feed-forward DNNs, convolutional nets (CNNs), and recurrent networks (RNNs/LSTMs). It implements stochastic gradient descent (SGD, error backpropagation) learning with automatic differentiation and parallelization across multiple GPUs and servers

TensorFlow
TensorFlow™ is an open source software library for numerical computation using data flow graphs. Nodes in the graph represent mathematical operations, while the graph edges represent the multidimensional data arrays (tensors) communicated between them. The flexible architecture allows you to deploy computation to one or more CPUs or GPUs in a desktop, server, or mobile device with a single API. TensorFlow was originally developed by researchers and engineers working on the Google Brain Team within Google's Machine Intelligence research organization for the purposes of conducting machine learning and deep neural networks research, but the system is general enough to be applicable in a wide variety of other domains as well

Smart services & smart clients: How micro-services change the way you build and deploy code
Experiences of Runscope using a microservice architecture. Some of the tools they use include: DynamoDB, ZooKeeper, Sidecar, HAProxy, Flask, Flask-RESTful. General principles: language agnosticism, no shared databases: every service owns its own data store - just expose an API. And a couple of choice quotes: "If you don't invest in infrastructure, don't invest in microservices". "You don't have to think about all this little details (databases, logging, etc.), you can focus on writing actual code." For me, the key point for a successful microservice architecture is to have a stable development platform - with standard, reusable components that change very little in the short-term.

ANTLRWorks: The ANTLR GUI Development Environment
ANTLRWorks is a novel grammar development environment for ANTLR v3 grammars written by Jean Bovet (with suggested use cases from Terence Parr). It combines an excellent grammar-aware editor with an interpreter for rapid prototyping and a language-agnostic debugger for isolating grammar errors. ANTLRWorks helps eliminate grammar nondeterminisms, one of the most difficult problems for beginners and experts alike, by highlighting nondeterministic paths in the syntax diagram associated with a grammar. ANTLRWorks' goal is to make grammars more accessible to the average programmer, improve maintainability and readability of grammars by providing excellent grammar navigation and refactoring tools, and address the most common questions and problems encountered by grammar developers

Virtualenv
virtualenv is a tool to create isolated Python environments. The basic problem being addressed is one of dependencies and versions, and indirectly permissions. Imagine you have an application that needs version 1 of LibFoo, but another application requires version 2. How can you use both these applications? Or more generally, what if you want to install an application and leave it be? If an application works, any change in its libraries or the versions of those libraries can break the application. In all these cases, virtualenv can help you. It creates an environment that has its own installation directories, that doesn't share libraries with other virtualenv environments (and optionally doesn't access the globally installed libraries either).

A Regular Expression Matcher
Code by Rob Pike
Exegesis by Brian Kernighan

Beautiful code is likely to be simple -- clear and easy to understand. Beautitful code is likely to be compact -- just enough code to do the job and no more -- but not cryptic, to the point where it cannot be understood. Beautiful code may well be general, solving a broad class of problems in a uniform way. One might even describe it as elegant, showing good taste and refinement.
