To dial a phone number in China from the USA, start with the US exit code (011), followed by China's country code (86), then the area code or mobile prefix and local number—no spaces or dashes needed. vonageforhome

Enter 011 + 86 + area code (2-4 digits) + local number (6-8 digits). vitelglobal

• Example for Beijing (area code 10, number 12345678): 011861012345678. 8x8 Common area codes include Beijing (10), Shanghai (21), and Guangzhou (20). rebtel

Enter 011 + 86 + mobile prefix (usually 1 followed by 10 digits, totaling 11 digits). vitelglobal

• Example: 0118613912345678. [8x8](https://www.8x8.com/blog/how-to-call-china-from-the-us

In Jira, an "idea" is not part of the standard project hierarchy (Project > Epic > Story/Task) but is a separate concept used for early-stage innovation and is managed in a dedicated tool called Jira Product Discovery (JPD). Ideas are for capturing and prioritizing potential work before it becomes part of the development backlog.

Here is a comparison of how ideas fit into the overall workflow:

Here is a breakdown of the standard Jira hierarchy for clarity:

For most Site Reliability Engineering (SRE) teams, a Kanban board is generally more suitable than Scrum. Kanban’s flexibility helps manage the dynamic, interrupt-driven nature of SRE work, which often involves urgent incidents, on-call rotations, and unpredictable tasks. Scrum is typically better for projects with predictable, time-boxed work—less common for SREs.

• Focuses on continuous flow and visualizing work in progress, making it easier to respond to real-time issues.
• Allows real-time task prioritization, accommodating urgent operational demands and interruptions.
• Supports ongoing maintenance and improvement work rather than fixed-length sprints.

• Emphasizes fixed sprints, planning, and review cycles, which suit teams with predictable workloads and iterative deliverables.
• Can present challenges for SRE teams, as unplanned work (incidents, emergencies) frequently disrupts sprint commitments.

A .gitkeep file is a convention-based placeholder file used to force Git to track an otherwise empty directory.

Git doesn't track empty directories - if you commit a folder with no files, it won't be included in your repository. The .gitkeep file solves this problem.

# Without .gitkeep - empty directory won't be tracked

• Compute-Bound: A problem is compute-bound when the speed of the calculation is limited by the CPU's (or GPU's) ability to perform mathematical operations. The processors are constantly working, and the bottleneck is their processing speed. They are waiting for nothing.
• I/O-Bound: A problem is I/O-bound (Input/Output bound) when the speed of the calculation is limited by the system's ability to read data from or write data to storage (disks, SSDs) or to transfer data between parts of the system (e.g., between nodes over a network, or between RAM and a processor). The processors are often idle, waiting for data to arrive.

The core idea of supercomputing is to solve a big problem faster by breaking it into smaller pieces and solving those pieces simultaneously on thousands of processors (CPUs/GPUs).
