Spencer Kimball is an American computer programmer, entrepreneur, and business executive. He is the CEO of Cockroach Labs, a company he co-founded in 2014. [1] His work as a programmer includes creating GNU Image Manipulation Program (GIMP) while still in college, [2] and assisting the source code development of CockroachDB, the namesake software of Cockroach Labs. In addition to Cockroach Labs, Kimball was involved in the founding of other tech startups including WeGo and Viewfinder. [3]

Early life and education

Kimball was born in 1974 to a Mormon family. He attended the University of California at Berkeley. While still a student in 1995, he developed the first version of GNU Image Manipulation Program (GIMP) as a class project, along with his roommate Peter Mattis. [4] [5] Kimball was also a member of a student club at Berkeley called the eXperimental Computing Facility (XCF). [6] During his time with XCF, he co-wrote the code for GIMP. [6] Kimball said in 1999 that, "From the first line of source code to the last, GIMP was always my 'dues' paid to the free software movement. After using emacs, gcc, Linux, etc., I really felt that I owed a debt to the community which had, to a large degree, shaped my computing development." [7] Kimball graduated with a B.A. in computer science from Berkeley in 1996.[ citation needed ]

Career

After graduation, Kimball mostly ended his relationship with the GIMP development community. He co-founded WeGo, a company providing tools for building web communities, in 1998 and served as the company's co-CTO. [8] While at XCF, he met Gene Kan, who was also a member, and the two would later begin working together on a file-sharing program for the Gnutella network, the open source Unix/Linux client gnubile. [9] In 2000, he created a web-based version of GIMP, OnlinePhotoLab.com, that was short-lived. [10] The technology was subsequently folded into Ofoto's online image manipulation tools.

Kimball started work with Google in Mountain View in 2002 [11] and relocated to Google's New York offices in 2004. As one of Google's engineers, he helped spearhead Colossus, a new version of the Google File System. [12] He also worked on the Google Servlet Engine. [13]

In January 2012, Kimball launched the company Viewfinder along with Mattis and Brian McGinnis, formerly of Lehman Brothers. [14] The company developed an app that allowed social media users to share photos, chat privately, and search photo history without leaving the app. [15] The company was acquired by Square, Inc. in December 2013. [16] Kimball moved to Square's New York City office where he became a senior member of the company's East Coast team. [17]

While at Google, Kimball used a database known as Bigtable and followed the development of its next generation, known as Spanner. [1] The database organizes data between thousands of servers to allow Google applications to stay online, even if an entire data center were to go offline. Kimball wanted to use this software but found there was nothing available outside of Google as either closed or open-source software with similar capabilities. [1] He elicited the help of Mattis, along with ex-Google Reader team member Ben Darnell. [18] They formed the company Cockroach Labs to provide commercial backing for CockroachDB, an open source project he started on GitHub in February 2014. [1] [19] Kimball serves as the company's chief executive officer and also contributes to the source code development of CockroachDB. [20] [21]

<span class="mw-page-title-main">GIMP</span> Open source raster graphics editor

The GNU Image Manipulation Program, commonly known by its acronym GIMP, is a free and open-source raster graphics editor used for image manipulation (retouching) and image editing, free-form drawing, transcoding between different image file formats, and more specialized tasks. It is extensible by means of plugins, and scriptable. It is not designed to be used for drawing, though some artists and creators have used it in this way.

<span class="mw-page-title-main">CinePaint</span> Free software for retouching bitmap frames of films

CinePaint is a free and open source computer program for painting and retouching bitmap frames of films. It is a fork of version 1.0.4 of the GNU Image Manipulation Program (GIMP). It enjoyed some success as one of the earliest open source tools developed for feature motion picture visual effects and animation work. The main reason for this adoption over mainline GIMP was its support for high bit depths which can be required for film work. The mainline GIMP project later added high bit depths in GIMP 2.9.2, released November 2015. It is free software under the GPL-2.0-or-later. In 2018, a post titled "CinePaint 2.0 Making Progress" announced progress, but, as of 2024, version 2.0 has not been released.

XCF, short for eXperimental Computing Facility, is the native image format of the GIMP image-editing program. It saves all of the data the program handles related to the image, including, among others, each layer, the current selection, channels, transparency, paths and guides.

Gene Kan was a British-born Chinese American peer-to-peer file-sharing programmer who was among the first programmers to produce an open-source version of the file-sharing application that implemented the Gnutella protocol. Kan worked together with Spencer Kimball on the program called "gnubile" licensed under the GNU General Public License. Kan graduated from the University of California, Berkeley in 1997 with a major in electrical engineering and computer science, and was a member of the student club the eXperimental Computing Facility (XCF).

Raster graphics editors can be compared by many variables, including availability.

Founded in 1986, the eXperimental Computing Facility (XCF) is an undergraduate computing-interest organization at University of California, Berkeley. The "Experimental" description was given in contrast to the Open Computing Facility and the Computer Science Undergraduate Association, which support most of the general-interest computing desires of the campus. As such, the XCF stands as a focus for a small group of computer-scientists uniquely interested in computer science.

Besides the Linux distributions designed for general-purpose use on desktops and servers, distributions may be specialized for different purposes including computer architecture support, embedded systems, stability, security, localization to a specific region or language, targeting of specific user groups, support for real-time applications, or commitment to a given desktop environment. Furthermore, some distributions deliberately include only free software. As of 2015, over four hundred Linux distributions are actively developed, with about a dozen distributions being most popular for general-purpose use.

<span class="mw-page-title-main">CockroachDB</span> Distributed database management system

CockroachDB is a source-available distributed SQL database management system developed by Cockroach Labs. The relational functionality is built on top of a distributed, transactional, consistent key-value store that can survive a variety of different underlying infrastructure failures, and is wire-compatible with PostgreSQL which means users can take advantage of a wide range of drivers and tools from the extensive PostgreSQL ecosystem. A CockroachDB cluster consists of a number of nodes that can be spread across failure domains such as data centres or public cloud regions. A cluster can be scaled both horizontally and vertically. It can provide high levels of resilience and availability and can be run in a variety of environments such as bare metal, VMs, containers and Kubernetes, both in private data centers and in the cloud. CockroachDB gets its name from cockroaches, as they are known for being disaster-resistant.

gRPC is a cross-platform high-performance remote procedure call (RPC) framework. gRPC was initially created by Google, but is open source and is used in many organizations. Use cases range from microservices to the "last mile" of computing. gRPC uses HTTP/2 for transport, Protocol Buffers as the interface description language, and provides features such as authentication, bidirectional streaming and flow control, blocking or nonblocking bindings, and cancellation and timeouts. It generates cross-platform client and server bindings for many languages. Most common usage scenarios include connecting services in a microservices style architecture, or connecting mobile device clients to backend services.

<span class="mw-page-title-main">GNOME 1</span> First major release of GNOME

GNOME 1 is the first major release of the GNOME desktop environment. Its primary goal was to provide a consistent user-friendly environment in conjunction with the X Window System. It was also a modern and free and open source software alternative to older desktop environments such as the Common Desktop Environment (CDE), but also to the K Desktop Environment (KDE). Each desktop environment was built-upon then proprietary-licensed widget toolkits, whereas GNOME's goal from the onset, was to be freely-licensed, and utilize the GTK toolkit instead.
