问题 I'm having troubles in encoding characters in utf-8. I'm using Django, and I get this error when I tried to send an Android notification with non-plain text. I tried to find where the source of the error and I managed to figure out that the source of the error is not in my project. In python shell, I type: 'ç'.encode('utf8') and I get this error: Traceback (most recent call last): File "<stdin>", line 1, in <module> UnicodeDecodeError: 'ascii' codec can't decode byte 0xe7 in position 0:

Ideally I would like to make the installation fail with an error message like "this package is only intend for RHEL7/CentOS7". How can I do this? More specifically how can I do this with CPack/CMake? Bonus points if you can also given an explanation suitable for

阅读更多关于 Replacing OAuth2 Implicit Grant with Authorization Code without Client Secret

问题 OAuth 2.0 Auth Code without Client Secret is being used in lieu of Implicit Grant for client-side JavaScript apps by a few companies. What are the general advantages / tradeoffs of using Auth Code without Client Secret vs. Implicit Grant? Are there more companies and/or standards organizations moving this way?

阅读更多关于 Is it possible to install aws-cli package without root permission?

问题 As title suggested, I haven't been able to find a good way to install aws-cli (https://github.com/aws/aws-cli/) without having the root access (or equivalent of sudo privileges). The way Homebrew setup on Mac is hinting at it may be possible, provided that a few directories and permissions are set in a way to facility future installs. However, I have yet to find any approach in Linux (specially, Red Hat Enterprise Linux or CentOS distroes). I am also aware of SCL from RHEL (https://access
