From Microsoft: C# and CLI under the Community Promise

Filed under
Microsoft

First the big news: Microsoft will be applying the Community Promise patent licensing to both C# and the CLI.

The announcement was done by Peter Galli at Microsoft over at Port25 and it states:

I have some good news to announce: Microsoft will be applying the Community Promise to the ECMA 334 and ECMA 335 specs.

ECMA 334 specifies the form and establishes the interpretation of programs written in the C# programming language, while the ECMA 335 standard defines the Common Language Infrastructure (CLI) in which applications written in multiple high-level languages can be executed in different system environments without the need to rewrite those applications to take into consideration the unique characteristics of those environments.

"The Community Promise is an excellent vehicle and, in this situation, ensures the best balance of interoperability and flexibility for developers," Scott Guthrie, the Corporate Vice President for the .Net Developer Platform, told me July 6.
It is important to note that, under the Community Promise, anyone can freely implement these specifications with their technology, code, and solutions.

You do not need to sign a license agreement, or otherwise communicate to Microsoft how you will implement the specifications.

Promises, promises

theopensourcerer.com: Microsoft made an interesting announcement, they are promising not to sue people for using Mono. Jolly good of them really, it is nice not being sued.

Lets just assume for the moment that this promise means what they say it means (forgetting about the partial implementations exclusion and the fact that the promise needed to be made in the first place) and it makes Mono totally safe to use now, even in countries with broken patent laws. I still won’t be using Mono.

FLOSSophobia

I have seen it many times. "Linux is a cancer". "Open sauce". "Linuxtard". I even remember the teacher who did not bring a laptop for her presentation and, when I offered her my Linux netbook, she rejected it as if I had presented her something illegal. She tried to use an old Windows computer instead but, when the computer failed, she ended up displaying her presentation with my Linux netbook. Clearly, this teacher's position was not based on ignorance or lack of expertise because she knew Linux existed and all she had to do was to display slides. Her refusal was due to indoctrination: she had learned that Linux and non-Microsoft office suites had to be rejected. Read more

Tryton and Python Deprecation Warnings

  • Trying Tryton
    The quest to find a free-software replacement for the QuickBooks accounting tool continues. In this episode, your editor does his best to put Tryton through its paces. Running Tryton proved to be a trying experience, though; this would not appear to be the accounting tool we are searching for. Tryton is a Python 3 application distributed under the GPLv3 license. Its home page mentions that it is based on PostgreSQL, but there is support for MySQL and SQLite as well. Tryton, it is said, is "a three-tier high-level general purpose application platform" that is "the core base of a complete business solution providing modularity, scalability and security". The "core base" part of that claim is relevant: Tryton may well be a solid base for the creation of a small-business accounting system, but it is not, out of the box, such a system itself.
  • Who should see Python deprecation warnings?
    As all Python developers discover sooner or later, Python is a rapidly evolving language whose community occasionally makes changes that can break existing programs. The switch to Python 3 is the most prominent example, but minor releases can include significant changes as well. The CPython interpreter can emit warnings for upcoming incompatible changes, giving developers time to prepare their code, but those warnings are suppressed and invisible by default. Work is afoot to make them visible, but doing so is not as straightforward as it might seem. In early November, one sub-thread of a big discussion on preparing for the Python 3.7 release focused on the await and async identifiers. They will become keywords in 3.7, meaning that any code using those names for any other purpose will break. Nick Coghlan observed that Python 3.6 does not warn about the use of those names, calling it "a fairly major oversight/bug". In truth, though, Python 3.6 does emit warnings in that case — but users rarely see them.
