From this definition it means, in context of python, to convert a string of bytes(coded) to Unicode(intelligible). In python3, strings are already decoded with Unicode. ref. More about encoding/decoding in context of Unicode is found in there. There is no string without encoding # If you followed the discussion so far, you probably already picked up on a crucial point about saving and reading text on a computer: Having a string without knowing its encoding makes no sense at all.https://jaaved.netlify.app/notes/curl_vs_python_requests_ssl_verification--20210929-180640/Sat, 29 Jul 2023 17:33:28 +0400https://jaaved.netlify.app/notes/curl_vs_python_requests_ssl_verification--20210929-180640/curl vs Having only the intermediate CA in the trust store is not sufficient for validation of the certificate, at least not with the current versions of Python. This feature would require the use of the OpenSSL flag X509_V_FLAG_PARTIAL_CHAIN for verification, which is neither currently exposed by Python nor set by default. Contrary to this curl sets this flag by default in newer versions and thus works.https://jaaved.netlify.app/notes/202212031539-difference_between_expose_and_ports_in_docker_compose_baeldung/Mon, 10 Jul 2023 14:21:35 +0400https://jaaved.netlify.app/notes/202212031539-difference_between_expose_and_ports_in_docker_compose_baeldung/Bookmark Notes # tags : URL # Clipped text # In this article, we covered part of the networking configurations in the Docker Compose. We analyzed and compared port configuration using the expose and ports sections. The expose section allows us to expose specific ports from our container only to other services on the same network. We can do this simply by specifying the container ports. The ports section also exposes specified ports from containers.https://jaaved.netlify.app/notes/display_manager_vs_desktop_environment_vs_window_manager--20211106-225241/Sun, 02 Jul 2023 16:45:55 +0400https://jaaved.netlify.app/notes/display_manager_vs_desktop_environment_vs_window_manager--20211106-225241/Summary fc # position ease box interval due front 2.5 0 0 2021-11-06T20:39:jkj05Z ref Desktop Environment # A desktop environment (DE) usually provides a window manager but a bunch of other stuff too: panels, start button, applets for volume, network etc. They provide an environment in which everything looks similar and easily recognisable, and provide GUI tools that allow you to do many admin tasks without having to type in a terminal.https://jaaved.netlify.app/notes/20210808211117-difference_between_messages_and_methods/Sat, 14 Jan 2023 20:23:30 +0400https://jaaved.netlify.app/notes/20210808211117-difference_between_messages_and_methods/Summary fc # A method is tied to a particular object. You find this in languages like Java and C++ where the method is bound early to the object at compile time. A message is an abstraction whereby the actual method that’s being called depends on runtime conditions. The object’s method is late-bound, thereby offering greater flexibility to the executing program. In Smalltalk, for example, an object may receive a message to invoke a non-existent method.https://jaaved.netlify.app/notes/mission_vs_vision--20221225-135125/Sat, 14 Jan 2023 20:22:11 +0400https://jaaved.netlify.app/notes/mission_vs_vision--20221225-135125/tags : Mission # A mission statement defines the organization’s business, its objectives, and how it will reach these objectives. is what your company is doing right now.

The PersistentVolume subsystem provides an API for users and administrators that abstracts details of how storage is provided from how it is consumed . To do this, we introduce two new API resources: PersistentVolume and PersistentVolumeClaim. A PersistentVolume (PV) # is a piece of storage in the cluster that has been provisioned by an administrator or dynamically provisioned using Storage Classes.https://jaaved.netlify.app/notes/202103281429-difference_between_user_story_and_feature/Sat, 14 Jan 2023 20:18:34 +0400https://jaaved.netlify.app/notes/202103281429-difference_between_user_story_and_feature/Summary # ref: link According to Kent Beck and Martin Fowler stories() and features are SYNONYMS: A user story is a chunk of functionality (some people use the word feature) that is of value to the customer.

StringIO is used for string data and BytesIO is used for binary data. This classes create file like object() that operate on string data. The StringIO and BytesIO classes are most useful in scenarios where you need to mimic a normal file. Example # import io s = io.StringIO() print(s.write("Hello World/n")) # ------->Output: 13 # adding to the memory buffer using print statement print("adding using the print",file = s) # get all of the data written in the file print(s.https://jaaved.netlify.app/notes/rocket_chat--20221231-153735/Sat, 14 Jan 2023 20:16:00 +0400https://jaaved.netlify.app/notes/rocket_chat--20221231-153735/# tags : Let every conversation flow - without compromise Secure and compliant collaboration platform.
