下，输入下面的命令来构建项目： $ cargo build Compiling hello_cargo v0.1.0 (file:///projects/hello_cargo) Finished dev [unoptimized + debuginfo] target(s) in 2.85 secs 这个命令会创建一个可执行文件 target/debug/hello_cargo （在 Windows /target/debug/hello_cargo 运行了程序，也 可以使用 cargo run 在一个命令中同时编译并运行生成的可执行文件： $ cargo run Finished dev [unoptimized + debuginfo] target(s) in 0.0 secs Running `target/debug/hello_cargo` Hello, world 会在运行之前重新构建项目，并会出现像这样的输出： $ cargo run Compiling hello_cargo v0.1.0 (file:///projects/hello_cargo) Finished dev [unoptimized + debuginfo] target(s) in 0.33 secs Running `target/debug/hello_cargo` Hello, world

of work were significantly behind schedule. Surprising discovery: only 50% of the source code in Dev/Test environments matched Prod. They fixed forward, but changes not put back into version control automated environment creation – time reduced from 8 weeks to 1 day b. ENABLE ON-DEMAND CREATION OF DEV, TEST, AND PRODUCTION ENVRIONMENTS i. Major contributing cause of issues stems from releases representing they get sick, you shoot them.” iii. Ensure consistency across all environments (Prod, pre-prod(s), dev, & new) iv. Immutable Infrastructure 1. Once created no changes are allowed 2. Changes must be

than the systems being monitored.” c. CREATE APPLICATION LOGGING TELEMETRY THAT HELPS PRODUCTION i. Dev & Ops create production telemetry as part of their daily workii. If it was important enough for an CREATION OF PRODUCTION METRICS AS PART OF DAILY WORK i. Create infrastructure to make it easy for Dev or Ops to create telemetry for functions built ii. Generate graphs with overlays of production changes ideally feature toggle off and fix-forward or use other Blue- Green, Canary release patterns b. DEV SHARES PAGER ROTATION DUTIES WITH OPS i. Complex systems will inevitably have unexpected problems

Automation: g. Myth—DevOps is Only for Open Source Software: 2. Foreword xix 3. Imagine a World Where Dev and Ops Become DevOps: a. THE CORE, CHRONIC CONFLICT i. Among them are the two following goals, which daily Work of Development a. CREATE SHARED SERVICES TO INCREASE DEVELOPER PRODUCTIVITY i. Enable Dev teams to spend more time building functionality, as opposed to created infrastructure ii. Automation LIAISON TO EACH SERVICE TEAM i. Reduces costs compared to embedded operations d. INTEGRATE OPS INTO DEV RITUALS i. Help better understand development culture. ii. Radiate operational concerns into the

with best performance and scalability on systems supporting epoll (Linux), kqueue (BSD/macOS), or /dev/poll (Solaris). Tornado will also run on Windows, although this configuration is not officially supported web framework and HTTP server together offer a full-stack alternative to WSGI [http://www.python.org/dev/peps/pep-3333/]. While it is possible to use the Tornado HTTP server as a container for other WSGI ) You can require that the user be logged in using the Python decorator [http://www.python.org/dev/peps/pep-0318/] tornado.web.authenticated. If a request goes to a method with this decorator, and the

keep the project working. When such incompatibilities occur, you'll typically want to upgrade your dev tools to versions that are compatible with the main project. Package Extensions A package "extension" PkgTemplates t = Template() t("MyPkg") This will create a blank package, "MyPkg", in your .julia/dev directory.
