Technological change | tc also often modelled using learning curve ex.ctc xtbtechnological change often included models e.g.climate change models often taken exogenous factor.days tc often included endogenous factor.means taken something influence. |
Technological change | today sectors maintain policy influence speed direction technological change.example proponents induced technological change hypothesis state policymakers steer direction technological advances influencing relative factor prices demonstrated way climate policies impact use fossil fuel energy specifically becomes relatively expensive.empirical evidence existence policyinduced innovation effects still lacking may attributed variety reasons outside sparsity models e.g.longterm policy uncertainty exogenous drivers directed innovation.related concept notion directed technical change emphasis price induced directional rather policy induced scale effects. |
Technological change | invention creation something new breakthrough technology.often included process product development relies research.demonstrated invention spreadsheet software.newly invented technologies conventionally patented.diffusion diffusion pertains spread technology society industry. |
Technological change | diffusion technology theory generally follows sshaped curve early versions technology rather unsuccessful followed period successful innovation high levels adoption finally dropping adoption technology reaches maximum potential market.case personal computer made way beyond homes business settings office workstations server machines host websites.technological change social process underpinning idea technological change social process general agreement importance social context communication.according model technological change seen social process involving producers adopters others government profoundly affected cultural setting political institutions marketing strategies.in free market economies maximization profits powerful driver technological change.generally technologies promise maximize profits owners incoming producing capital developed reach market. |
Technological change | technological product fails meet criterion even though may satisfy important societal needs eliminated.therefore technological change social process strongly biased favor financial interests capital.currently well established democratic processes voting social environmental desirability new technology prior development marketing would allow average citizens direct course technological change.elements diffusion emphasis four key elements technological change process innovative technology communicated certain channels members social system adopt period time.elements derived everett m. rogers diffusion innovations theory using communicationstype approach. |
Technological change | innovation rogers proposed five main attributes innovative technologies influence acceptance.called criteria accto stands advantage compatibility complexity trialability observability.relative advantage may economic noneconomic degree innovation seen superior prior innovations fulfilling needs.positively related acceptance e.g.higher relative advantage higher adoption level vice versa. |
Technological change | compatibility degree innovation appears consistent existing values past experiences habits needs potential adopter low level compatibility slow acceptance.complexity degree innovation appears difficult understand use complex innovation slower acceptance.trialability perceived degree innovation may tried limited basis positively related acceptance.trialability accelerate acceptance smallscale testing reduces risk.observability perceived degree results innovating visible others positively related acceptance. |
Technological change | communication channels communication channels means source conveys message receiver.information may exchanged two fundamentally different yet complementary channels communication.awareness often obtained mass media uncertainty reduction leads acceptance mostly results facetoface communication.social system social system provides medium boundaries within innovation adopted.structure social system affects technological change several ways. |
Technological change | social norms opinion leaders change agents government consequences innovations involved.also involved cultural setting nature political institutions laws policies administrative structures.time time enters acceptance process many ways.time dimension relates innovativeness individual adopter relative earliness lateness innovation adopted.economics economics technological change change set feasible production possibilities.a technological innovation hicks neutral following john hicks change technology change ratio capitals marginal product labours marginal product given capitaltolabour ratio. |

Distributed version control | compared centralized version control enables automatic management branching merging speeds operations except pushing pulling improves ability work offline rely single location backups.git worlds popular version control system distributed version control system.in software development author joel spolsky described distributed version control systems possibly biggest advance software development technology past ten years.distributed vs. centralized distributed version control systems dvcs use peertopeer approach version control opposed client–server approach centralized systems.distributed revision control synchronizes repositories transferring patches peer peer.single central version codebase instead user working copy full change history.advantages dvcs compared centralized systems includeallows users work productively connected network.common operations commits viewing history reverting changes faster dvcs need communicate central server. |
Distributed version control | dvcs communication necessary sharing changes among peers.allows private work users use changes even early drafts want publish.working copies effectively function remote backups avoids relying one physical machine single point failure.allows various development models used using development branches commanderlieutenant model.permits centralized control release version projecton foss software projects much easier create project fork project stalled leadership conflicts design disagreements.disadvantages dvcs compared centralized systems includeinitial checkout repository slower compared checkout centralized version control system branches revision history copied local machine default.the lack locking mechanisms part centralized vcs still plays important role comes nonmergeable binary files graphic assets complex single file binary xml packages e.g.office documents powerbi files sql server data tools bi packages etc..additional storage required every user complete copy complete codebase history.increased exposure code base since every participant locally vulnerable copy.some originally centralized systems offer distributed features.example subversion able many operations network.team foundation server visual studio team services host centralized distributed version control repositories via hosting git.similarly distributed systems offer features mitigate issues checkout times storage costs virtual file system git developed microsoft work large codebases exposes virtual file system downloads files local storage needed.work model distributed model generally better suited large projects partly independent developers linux kernel project developers work independently submit changes merge rejection. |
Distributed version control | distributed model flexibly allows adopting custom source code contribution workflows.integrator workflow widely used.centralized model developers must serialize work avoid problems different versions.central branch repositories every project central repository considered official repository managed project maintainers.developers clone repository create identical local copies code base. |
Distributed version control | source code changes central repository periodically synchronized local repository.the developer creates new branch local repository modifies source code branch.development done change needs integrated central repository.pull requests contributions source code repository uses distributed version control system commonly made means pull request also known merge request.contributor requests project maintainer pull source code change hence name pull request.maintainer merge pull request contribution become part source base.the developer creates pull request notify maintainers new change comment thread associated pull request. |
Distributed version control | allows focused discussion code changes.submitted pull requests visible anyone repository access.pull request accepted rejected maintainers.once pull request reviewed approved merged repository.depending established workflow code may need tested included official release.therefore projects contain special branch merging untested pull requests. |
