workflow

ylbtech-Workflow：Workflow 百科 工作流（Workflow），指“ 业务 过程 的 部分或整体 在 计算机 应用环境下 的 自动化 ”。是对工作流程及其各操作步骤之间业务规则的抽象、概括描述。在计算机中，工作流属于计算机支持的 协同工作（CSCW） 的一部分。后者是普遍地研究一个群体如何在计算机的帮助下实现协同工作的。 工作流主要解决的主要问题是：为了实现某个业务目标，利用计算机在多个参与者之间按某种预定规则自动传递文档、信息或者任务。 工作流概念起源于生产组织和 办公自动化 领域，是针对日常工作中具有固定 程序 活动而提出的一个概念，目的是通过将工作分解成定义良好的任务或角色，按照一定的规则和 过程 来执行这些任务并对其进行监控，达到提高工作效率、更好的控制过程、增强对客户的服务、有效管理业务流程等目的。尽管工作流已经取得了相当的成就，但对工作流的定义还没有能够统一和明确。 Georgakopoulos给出的工作流定义是：工作流是将一组任务组织起来以完成某个经营 过程 ：定义了任务的 触发顺序和触发条件 ，每个任务可以由一个或多个 软件系统 完成，也可以由一个或一组人完成，还可以由一个或多个人与软件系统协作完成。 1993年 工作流管理 联盟(Workflow Management Coalition，WfMC)作为工作流管理的标准化组织而成立

I work for a company which builds embedded systems using Linux. Historically we've always used CVS to store our kernel work. Our kernels end up being a collection of: Drivers for our proprietary hardware Random fixes for bits of Linux we use Non-proprietary hardware drivers Random yukky hacks to tailor Linux for our application We're at the stage where we would like to rebase some of our older kernels on newer versions as well as fixing up our archaic CVS workflow to something based on changesets. The obvious choice is git. I'm struggling to come up with a sensible workflow. I have exported

Wondering if it is possible to have a version control of a MySQL database. I realize this question has been asked before however the newest is almost a year ago, and at the rate things change... The problem is coming that each developer has apache/MySQL/PHP on their own computers to which they sometimes edit the database. Its rather inconvenient if they have to send an email to all the other developers and then manually edit the test servers database. How do you deal with this problem? Thanks This is not a MySQL-related solution in itself, but we've had a lot of success with a product called

The company I work for wants to have monthly releases, and I am trying to convince them to switch to git. I believe the proper git-way to handle this is to have a integration branch for each release (i.e. monthly) and have feature branches off the integration branches for new development and changes. The environment is loaded with interdependencies and sometimes a feature has to be postponed to a different month because of delays in required features from other external systems. The projects will generally have activity on 2-3 integration branches in parallel and the activity is confined to a

温馨提示：本文中Alfred是Mac平台的工具，不适用于其他平台。 Alfred 是Mac平台上被很多人吹爆的一款效率提升软件，我刚毕业工作的时候就看到公司内网有人推荐，但没有尝试。 后来我跳槽后自己买了Macbook pro，在努力把笔记本打造成高效开发工具时，又重新发现了这个app，又毫不犹豫的购买了Powerpack，结合一些workflow，很多繁琐的工作变得非常简单，比如之前百度搜索一个东西，需要打开浏览器，然后打开百度，再输入要搜的词，再点搜索一套组合拳下来几十秒就过去了，有了Alfred 快捷键+触发词+搜索词+回车 几秒钟搞定。下图是我最近一月来每天的Alfred的使用频率，工作日平均每天有30+次的使用率。 那究竟Alfred是啥？Mac又个功能叫“聚焦”，它可以帮你搜索本机的一些内容，比如文件、应用程序、浏览器书签……，但功能仅限于此。Alfred类似有聚焦，操作方式也类似，但功能比聚焦强大的多。除了聚焦搜拥有的简单搜索功能，Alfred还可以设置action，用某个关键词触发一个动作，或者设置快捷键。默认继承了一些系统快捷设置，比如mac用户从windows过来最不习惯的就是不能快速锁屏，甚至不知道怎么锁屏，通过Alfred的快捷命令就可以秒锁屏了。 我个人最喜欢也是最常用的就是ClickBoard Histroy，它可以保存你近期复制粘贴的所有东西

What is the benefit of using Windows Workflow foundation (WF) versus rolling your own workflow framework? From what I can tell, WF only provides a pretty bare-bones runtime engine, a bunch of classes, and a schema (XAML-based) for defining workflows. All the hard stuff such as persistence, providing a host process for the runtime, and implementing distributed workflows (across processes) is left up to you. Plus there is a learning curve to using WF... if we created our own workflow framework we would simply leverage skills that all developers already have (C#, XML, SQL, etc). I saw this blog

I remember coming across R users writing that they use "Revision control" ( e.g: "Source control" ), and I am curious to know: How do you combine "Revision control" with your statistical analysis workflow? Two (very) interesting discussions talk about how to deal with the workflow. But neither of them refer to the revision control element: How to organize large R programs? Workflow for statistical analysis and report writing A Long Update To The Question : Following some of the people's answers, and Dirk's question in the comment, I would like to direct my question a bit more.

Problem Is there any way in Airflow to create a workflow such that the number of tasks B.* is unknown until completion of Task A? I have looked at subdags but it looks like it can only work with a static set of tasks that have to be determined at Dag creation. Would dag triggers work? And if so could you please provide an example. I have an issue where it is impossible to know the number of task B's that will be needed to calculate Task C until Task A has been completed. Each Task B.* will take several hours to compute and cannot be combined. |---> Task B.1 --| |---> Task B.2 --| Task A ------
