Rackspace ending open source free hosting program, invocing for January 2020

Are you an open source maintainer? Have you used Rackspace's free hosting offer any time in the past 10 years? Rackspace has ended the program. People are getting invoices for Jan. Get off the servers and close your account or you will be charged full retail rate.
-- Van Lindberg, General Counsel, Python Software Foundation. @ Twitter

Offers and alternatives are mentioned in thread.

Reshares / links appreciated.

[Blog]Python: (Fast) alles ist eine Liste #Python #mysql #NULL
Python: (Fast) alles ist eine Liste
 
TIL: #Python Wenn ich aus einer #mysql Tabelle nur einen Wert abfrage, kommt der nicht als Liste, sondern als Einzelwert. Ich kann ihn trotzdem mit wert [0]abfragen – außer er ist NULL (Python: None); dann fällt Python auf die Nase.

Erinnert Ihr Euch an das Problem mit dem Zufallsfoto, bei dem seltsamerweise bei einer Abfrage ein Vergleich gegen None (Python) bzw. NULL (mysql) nicht funktionieren wollte? – Genau. Ich fragte in diesem Fall nur einen Wert aus der „Copyright“-Tabelle* von Piwigo ab, nicht wie sonst aus anderen Tabellen mehrere Werte gleichzeitig. In diesem Fall greift auch COALESCE im SELECT-Statement nicht – es kommt trotzdem ein None in Python an. Und wenn ich dann wert [0]vergleichen will, macht's Bumm. Lösung: Ich vergleiche wert, nicht wert[0], und – ja, das ist dann wohl so ein Fall von „kaum macht man's richtig, schon funktioniert's“ … m)
  • eigentlich geht's da um Lizenzen, nicht um ©, da haben die Piwigo-Leute wohl was falsch verstanden …
So, und jetzt bau ich das von der Development-Version in die produktive Version ein.
 
We hired one in our #Alameda office but are looking for another in either our #Minneapolis #Minnesota office or the #California office

Nice-to-haves*:
Knowledge of C/C++ and #Java and experience with #PHP/MySQL
Knowledge of Unix & #Linux (we previously supported #BSD, #Solaris, and perhaps some others, but just Linux now)
Basic networking experience
Experience with Perforce, #Git, or other version control software is desirable
Bachelor’s Degree in Computer Science or similar or relevant work experience
2 or more years’ experience providing technical support directly to enterprise customers

These are listed as requirements on the site, but they make zero since to me. There is literally no one on the Minneapolis team that knows C/C++. We do have a C/C++ API, so yes, it would be good if you knew that, but most people use our derived APIs (#Perl, #Python, .NET, #Ruby, #PHP, and maybe that is it). Java, like #C, is a native API.
Also, we do support #Windows and #Mac, so unclear why knowledge of that is not listed.

Experience in customer support or customer-facing role
Strong analytics and problem-solving skills
Strong debugging skills
Ability to work in a team environment and contribute ideas and improvements
Able to work well under pressure and prioritize accordingly
Responsibilities:
Represent Perforce as the first point of contact for customer’s technical requests.
Review and research customer issues to determine and provide the best resolution.
Develop and maintain technical expertise in assigned areas of product functionality and utilize it effectively to help customers.
Resolve database and performance issues.
Research, document, and escalate cases according to procedure.
Provide customer driven feedback to functional areas in order to influence process/product improvements.
Author technical documents on common issues and solutions in order to build the knowledge base.
Positive attitude - Support engineers are required to be respectful, fair, gracious, and knowledgeable.
Create and set up test environments to reproduce and resolve customer issues.
Recreate customer environments to reproduce issues and experiment with possible solutions.

A 1000-line Python script outputs different results on different operating systems, tainting 100 published studies.

A Code Glitch May Have Caused Errors In More Than 100 Published Studies - VICE



Scientists in Hawaiʻi have uncovered a glitch in a piece of code that could have yielded incorrect results in over 100 published studies that cited the original paper.

The glitch caused results of a common chemistry computation to vary depending on the operating system used, causing discrepancies among Mac, Windows, and Linux systems. The researchers published the revelation and a debugged version of the script, which amounts to roughly 1,000 lines of code, on Tuesday in the journal Organic Letters.

“This simple glitch in the original script calls into question the conclusions of a significant number of papers on a wide range of topics in a way that cannot be easily resolved from published information because the operating system is rarely mentioned,” the new paper reads. “Authors who used these scripts should certainly double-check their results and any relevant conclusions using the modified scripts in the [supplementary information].”
[…]
Luo’s results did not match up with the NMR values that Williams’ group had previously calculated, and according to Sun, when his students ran the code on their computers, they realized that different operating systems were producing different results. Sun then adjusted the code to fix the glitch, which had to do with how different operating systems sort files.

The dumb reason your fancy Computer Vision app isn’t working: Exif Orientation



Exif metadata is not a native part of the Jpeg file format. It was an afterthought taken from the TIFF file format and tacked onto the Jpeg file format much later. This maintained backwards compatibility with old image viewers, but it meant that some programs never bothered to parse Exif data.

Most Python libraries for working with image data like numpy, scipy, TensorFlow, Keras, etc, think of themselves as scientific tools for serious people who work with generic arrays of data. They don’t concern themselves with consumer-level problems like automatic image rotation — even though basically every image in the world captured with a modern camera needs it.

This means that when you load an image with almost any Python library, you get the original, unrotated image data. And guess what happens when you try to feed a sideways or upside-down image into a face detection or object detection model? The detector fails because you gave it bad data.

You might think this problem is limited to Python scripts written by beginners and students, but that’s not the case! Even Google’s flagship Vision API demo doesn’t handle Exif orientation correctly

Would you like to experiment with language development? Is there something you need to parse, but you can't find a suitable tool? Perhaps Yakety can help.

Yakety itself is a Python library for generating recursive descent parsers from EBNF grammars. Included with it is a wrapper tool (ykt), which will use a grammar file to parse stdin, and then emit a representation of the parse tree (either structured text or JSON) to stdout, allowing you to build and test parsers with minimal friction. Also included is a tool for converting the JSON parse tree to a form suitable for Graphviz, letting you create visualizations of the parser's output.

The code is based on that presented in the article Recursive Descent: The Next Iteration.

Enjoy, and I hope you find it useful.

How we made Monty Python’s Life of Brian

John Cleese had wanted to play Brian. Graham Chapman had been drinking quite a lot, and John thought we needed a safe pair of hands for the lead role. But Graham gave up drinking just before and was dry throughout. He had a kind of decency that anchored the whole film. He was also a qualified doctor, so he was very useful looking after cast and crew while we were shooting in Tunisia, with all the stomach upsets people had.

Amazing heads-up article in local paper today about a free software/hardware project to literally save human lives.
The Open Artificial Pancreas System project is an open and transparent effort to make safe and effective basic Artificial Pancreas System (APS) technology widely available to more quickly improve and save as many lives as possible and reduce the burden of Type 1 diabetes.
