Currently list is longer than 35 projects, during change from Polish to English I have added one new project - and this is why title says 35 instead 34 ;). After updates there are even more! Sorry for your confusion.Google is one of the biggest companies supporting OpenSource movement, they released more than 500 open source projects(most of them are samples showing how to use their API). In this article I will try to write about most interesting and free releases from Google, some of them might be abandoned.
List of projects developed at Google and released as opensource (thanks @dobs from reddit) can be displayed also here

- The Google Collections Library is a set of new collection types, implementations and related goodness for Java 5 and higher, brought to you by Google. It is a natural extension of the Java Collections Framework you already know and use.
- Google styleguide
- Every major open-source project has its own style guide: a set of conventions (sometimes arbitrary) about how to write code for that project. It is much easier to understand a large codebase when all the code in it is in a consistent style. "Style" covers a lot of ground, from “use camelCase for variable names” to “never use global variables” to “never use exceptions.” This project holds the style guidelines we use for Google code. If you are modifying a project that originated at Google, you may be pointed to this page to see the style guides that apply to that project. This is worth reading.

- Scarcity is a framework for concurrent garbage collection in C++. The framework is organized around the principle of "policy-based design", meaning that behavior are customized and extended via template parameters. Policy-based design facilitates seamless integration with a broad set of VMs and other runtime environments by allowing the host environment to replace any aspect of the framework, such as thread synchronization primitives, atomic data types, error logging facilities, tracing strategies and so on.
- Google concurrency library
- A concurrency library for C++. Here is getting started guide.
- CppClean attempts to find problems in C++ source that slow development particularly
in large code bases. It is similar to lint; however, CppClean focuses on finding global
inter-module problems rather than local problems similar to other static analysis tools.
The goal is to find problems that slow development in large code bases that are modified
over time leaving unused code. This code can come in many forms from unused functions,
methods, data members, types, etc to unnecessary #include directives. Unnecessary #includes
can cause considerable extra compiles increasing the edit-compile-run cycle.
Here are some details about implementation
- Unladen swallow
- An optimized branch of CPython, intended to be fully compatible and significantly faster.
Unladen Swallow is Google-sponsored, but not Google-owned. The engineers on the project are full-time Google engineers,
but ultimately this an open-source project, not really that different from Chrome or Google Web Toolkit.
Here is Getting Started Guide.
- Closure Tools
Closure Templates simplify the task of dynamically generating HTML.
Here is documentation.
- SPDY is an experiment with protocols for the web. Its goal is to reduce the latency of web pages.
SPDY (pronounced "SPeeDY") is an application-layer protocol for transporting content over the web, designed
specifically for minimal latency. There is SPDY-enabled Google Chrome browser and open-source web server.
In lab tests, Google team had observed up to 64% reductions in page load times when using SPDY.
- There are a variety of C unit testing frameworks available however many of them are fairly complex and require the latest compiler technology. Some development requires the use of old compilers which makes it difficult to use some unit testing frameworks. In addition many unit testing frameworks assume the code being tested is an application or module that is targeted to the same platform that will ultimately execute the test. Because of this assumption many frameworks require the inclusion of standard C library headers in the code module being tested which may collide with the custom or incomplete implementation of the C library utilized by the code under test. Cmockery only requires a test application is linked with the standard C library which minimizes conflicts with standard C library headers. Also, Cmockery tries to avoid the use of some of the newer features of C compilers. For more information checkout manual.

- A parallel C++ implementation of fast Gibbs sampling of Latent Dirichlet Allocation
- stubl - Stateless (IPv6) Tunnel Broker for LANs
- Stubl is a transition mechanism for providing a basic level of IPv6 connectivity to individual nodes on a private network. All that's required is a single Linux server with an IPv6 /64 subnet routed to it. The Stubl server consists of a Linux kernel module (stubl.ko) for handling the tunnel packets, and an HTTP server (stubl_http.py) for calculating clients' addresses and providing tunnel setup instructions. The main advantage of Stubl is that it allows a user on the network, running any major OS, to get a working IPv6 connection with nothing but a few lines of shell commands. This makes it very easy for developers to start getting familiar with the protocol, with minimal administrative overhead.
- dcsbwt is a data compressor program and library based on the Burrows-Wheeler transform.

The encoding strategy is largely based on Bentley-McIlroy 99: "Data Compression Using Long Common Strings." A library with a simple API is included, as well as a command-line executable that can apply the encoder and decoder to source, target, and delta files. A slight variation from the draft standard is defined to allow chunk-by-chunk decoding when only a partial delta file window is available.
- Update Engine is a flexible Mac OS X framework that can help developers keep their products up-to-date. It can update nearly any type of software, including Cocoa apps, screen savers, and preference panes. It can even update kernel extensions, regular files, and root-owned applications. Update Engine can even update multiple products just as easily as it can update one.
- Google site map generator
- Sitemaps are an easy way for webmasters to inform search engines about pages on their sites that are available for crawling. By creating and submitting Sitemaps to search engines, you are more likely to get better freshness and coverage in search engines. Google Sitemap Generator is a tool installed on your web server to generate the Sitemaps automatically. Unlike many other third party Sitemap generation tools, Google Sitemap Generator takes a different approach: it will monitor your web server traffic, and detect updates to your website automatically.
- Google Pose Optimizer
- The Google pose optimizer (GPO) is a C++ library that allows reconstruction of the pose of a sensor platform (i.e. its position and orientation over time) based on information from sensors such as GPS, accelerometers and rate gyroscopes. GPO does not provide real-time localization in the way that a Kalman filter would, instead it generates the pose as a result of a large off-line optimization. This produces better results. Here is wiki.
- Google dnswall
- dnswall is a daemon that filters out private IP addresses in DNS responses. It is designed to be used in conjunction with an existing recursive DNS resolver in order to protect networks against DNS rebinding attacks. For details of the attack and various defenses, including dnswall, see http://crypto.stanford.edu/dns/.
- Google timezone
