Stack Exchange

Stack Exchange NetworkcstheoryMathematics Stack Exchange
As of September 2018, the three most actively-viewed sites in the network are: Stack Overflow, Super User, and Ask Ubuntu. All sites in the network are modelled after the initial site Stack Overflow, a Q&A site for computer programming questions created by Jeff Atwood and Joel Spolsky. Further Q&A sites in the network are established, defined and eventually if found relevant brought to creation by registered users through a special site named Area51.

List of Internet entrepreneurs

internet entrepreneurtechnology entrepreneurbillionaire internet entrepreneur
An Internet entrepreneur is an owner, founder or manager of an Internet based business. This list includes Internet company founders, and people brought on to companies for their entrepreneurship skills, not simply for their general business or accounting acumen, as is the case with some CEOs hired by companies started by entrepreneurs.

Computer programming

programmingcodingcomputer programmer
Computer programming is the process of designing and building an executable computer program for accomplishing a specific computing task. Programming involves tasks such as analysis, generating algorithms, profiling algorithms' accuracy and resource consumption, and the implementation of algorithms in a chosen programming language (commonly referred to as coding ). The source code of a program is written in one or more programming languages. The purpose of programming is to find a sequence of instructions that will automate the performance of a task for solving a given problem.

Software development

developmentdevelopedapplication development
Software development is the process of conceiving, specifying, designing, programming, documenting, testing, and bug fixing involved in creating and maintaining applications, frameworks, or other software components. Software development is a process of writing and maintaining the source code, but in a broader sense, it includes all that is involved between the conception of the desired software through to the final manifestation of the software, sometimes in a planned and structured process. Therefore, software development may include research, new development, prototyping, modification, reuse, re-engineering, maintenance, or any other activities that result in software products.

His method was inspired by Joel Spolsky, who advocated giving programmers a finite number of votes to prioritize software development. White asked users to vote, instead of using programmers. White, together with Lance Ivy and Marcus Nelson, launched UserVoice in February 2008. An early adopter was Stack Overflow, run by Spolsky. UserVoice had 13 employees and 4,000 clients, with 23 million users participating by 2011. UserVoice Feedback collects and prioritizes suggestions from customers as they list ideas and vote on them. This voting can occur through the SmartVote comparison testing feature.


Speakers at the first four-day Webstock in 2006 included Dori Smith, Roger Hudson, Russ Weakley, Rachel McAlpine, Douglas Bowman, Heather Hesketh, Russell Brown (PublicAddress), Tony Chor (Microsoft), Darren Fittler, Kelly Goto, Ben Goodger (Firefox / Google), Rowan Simpson (Trade Me), Donna Maurer, Joel Spolsky, Kathy Sierra, Andreas Girardet (creator of Yoper) and Steve Champeon.

. * — podcast with Joel Spolsky and Jeff Atwood (creators of Stack Exchange) and Anton Geraschenko (creator of MathOverflow). Terence Tao compared it to "the venerable newsgroup sci.math, but with more modern, 'Web 2.0' features.". John C. Baez writes that "website 'Math Overflow' has become a universal clearinghouse for math questions". According to Gil Kalai, MathOverflow "is ran [sic] by an energetic and impressive group of very (very very) young people". Jordan Ellenberg comments that the website "offers a constantly changing array of new questions" and is "addictive" in a "particularly pure form", as he compares it to the Polymath Project.


Trello was released at a TechCrunch event by Fog Creek founder Joel Spolsky. Wired magazine named the application in September 2011 one of "The 7 Coolest Startups You Haven't Heard of Yet". Lifehacker said "it makes project collaboration simple and kind of enjoyable". In 2014, it raised $10.3 million in funding from Index Ventures and Spark Capital. In 2015, Trello launched third-party integrations with tools such as Slack, GitHub and Salesforce for its paying users. In 2016, Trello opened this platform to additional developers with the launch of its "Power-Ups Platform" for developers wanting to integrate their services with Trello.

Discourse (software)

DiscourseDiscourse platform
Discourse is an open source Internet forum and mailing list management software application founded in 2013 by Jeff Atwood, Robin Ward, and Sam Saffron. Discourse received funding from First Round Capital and Greylock Partners. The application is written with Ember.js and Ruby on Rails. PostgreSQL serves as its back-end database management system. From a usability perspective, Discourse breaks with existing forum software by including features recently popularized by large social networks, such as infinite scrolling, live updates, expanding links, and drag and drop attachments.


gamifiedgameGamified eCommerce
On the programming question-and-answer site Stack Overflow users receive points and/or badges for performing a variety of actions, including spreading links to questions and answers via Facebook and Twitter. A large number of different badges are available, and when a user's reputation points exceed various thresholds, the user gains additional privileges, eventually including moderator privileges. Gamification can be used for ideation (structured brainstorming to produce new ideas).

Reputation system

reputation systemsfeedback systemsreputation points
For example, on the Stack Overflow community, reputation points can be spent on question "bounties" to incentivize other users to answer the question. Even without an explicit spending mechanism in place, reputation systems often make it easier for users to spend their reputation without harming it excessively. For example, a driver with a high ride acceptance score (a metric often used for driver reputation) on a ride-sharing service may opt to be more selective about his or her clientele, decreasing the driver's acceptance score but improving his or her driving experience.

Microsoft Excel is a spreadsheet developed by Microsoft for Windows, macOS, Android and iOS. It features calculation, graphing tools, pivot tables, and a macro programming language called Visual Basic for Applications. It has been a very widely applied spreadsheet for these platforms, especially since version 5 in 1993, and it has replaced Lotus 1-2-3 as the industry standard for spreadsheets. Excel forms part of Microsoft Office.
