Spyder – The Scientific Python IDE for Data Science

Filed under
Development

I don’t know how many of our readers are research scientists, data analysts, etc. but today, we introduce an IDE that is ideal for Python development and it goes by the name of Spyder.

Spyder is an Open Source IDE written in Python for Python development with a focus on research, data analysis, and scientific package creation. It boasts a well-planned User Interface with interactive options, customizable layouts, and toggle-able sections.

Its features include a multi-language editor with automatic code completion, real-time code analysis, go-to definitions, etc. It also contains a history log, developer tools, a documentation viewer, a variable explorer, and an interactive console, among other perks.

  • Intel Opens Up nGraph Source Code For DNN Model Compiler

    Intel tonight announced they are open-sourcing their nGraph compiler code, which serves as a framework-neutral deep neural network model compiler.

    Intel claims with nGraph and Xeon Scalable hardware that researchers can obtain up to 10x performance improvements over previous TensorFlow integrations, as one example. Besides TensorFlow, nGraph also supports PyTorch, MXNet, Neon, Caffe2, and CNTK while also planning to support other frameworks moving forward.

  • Why it's finally time to give up on the name JavaScript

    An iOS developer has apparently received a cease and desist notice from Oracle over the use of the word "JavaScript" in the title of their app. The developer, Tyanya Software, shared the notice on perennial internet soapbox Reddit to seek advice on how to fight the order.

    [...]

    If user reviews are any indication, the app is not even particularly good, with reviewers stating things such as "Not ready for production," "Does not work as advertised," and "Waste of money, don't buy this." The last update to the app was in 2014, which the changelog notes was only an upgrade to add support for iOS 8. The app developer is at least honest about the intent behind the unwieldy name for the app, saying in a Reddit comment that "we game the App Store ranking by adding all the keywords to the app name."

    While Oracle has a duty to protect their trademarks, this type of legal bludgeoning underscores a historical problem that has been left unaddressed for too long: JavaScript is a terrible name for the thing being described.

    It has nothing to do with Java, an actual product developed by Sun (now owned by Oracle). JavaScript was developed at Mozilla, and the name was changed during beta releases of Netscape Navigator 2.0 from "LiveScript" to "JavaScript." It has, for some time, caused confusion among casual web users about the difference between Java and JavaScript. Given that ECMAScript is also a trademarked term, it seems best to revert to calling the language "LiveScript" to undercut trademark-related legal posturing.

    [...]

    Oracle declined to comment on this story.

  • New PyPI launched

    The new PyPI has been launched. Browser traffic and API calls (including "pip install") have been redirected from the old pypi.python.org to the new site. The old PyPI will shut down on April 30. LWN covered the new PyPI last week.

  • Pip 10.0 has been released

    The release of pip 10.0 has been announced. Some highlights of this release include the removal of Python 2.6 support, limited PEP 518 support (with more to come), a new "pip config" command, and other improvements.

Programming: Taxonomy of Tech Debt, Python and More

  • A Taxonomy of Tech Debt

    Hi there. I’m Bill “LtRandolph” Clark, and I’m the engineering manager for the Champions team on LoL. I’ve worked on several different teams on League over the past years, but one focus has been consistent: I’m obsessed with tech debt. I want to find it, I want to understand it, and where possible, I want to fix it.

    When engineers talk about any existing piece of technology - for example League of Legends patch 8.4 - we often talk about tech debt. I define tech debt as code or data that future developers will pay a cost for. Countless blog posts, articles, and definitions have been written about this scourge of software development. This post will focus on types of tech debt I’ve seen during my time working at Riot, and a model for discussing it that we’re starting to use internally. If you only take away one lesson from this article, I hope you remember the “contagion” metric discussed below.

  • 6 Python datetime libraries

    Once upon a time, one of us (Lacey) had spent more than an hour staring at the table in the Python docs that describes date and time formatting strings. I was having a hard time understanding one specific piece of the puzzle as I was trying to write the code to translate a datetime string from an API into a Python datetime object, so I asked for help.

Programming/Development: That’s How C Does It, LLVM, Java EE

  • This Week in Programming: That’s How C Does It

    I had grand ambitions this week. I’d come across a smattering of articles delving into the history of programming languages, practices, and other Internet-based tidbits. I’d pondered a pithy title like “if !mistake(history) do repeat” and dug through my source materials for evidence, but came up a bit empty-handed. In the end, the line that really summed up this week’s theme was found at the closing of an interesting article asking why does “=” mean assignment?

  • Intel Tremont CPU Support Added To LLVM's Clang Compiler

  • SAP okays Java EE being Eclipsed, six months after Oracle's announcement

    SAP has revealed its attitude to Oracle’s decision to let go of Java EE and have it tended by the Eclipse Foundation.

    SAP’s position is simple: it’s cool with it.

    “The announcement of Oracle to handover stewardship of Java EE to the Eclipse foundation is a forward-looking process targeting future releases of the technology stack,” says the company’s “”stance” on the matter.

  • Apache Subversion 1.10 Release Notes

    Apache Subversion 1.10 is a superset of all previous Subversion releases, and is as of the time of its release considered the current "best" release. Any feature or bugfix in 1.0.x through 1.9.x is also in 1.10, but 1.10 contains features and bugfixes not present in any earlier release. The new features will eventually be documented in a 1.10 version of the free Subversion book (svnbook.red-bean.com).

  • Subversion 1.10 Released With LZ4 Compression, New Conflict Resolver

    For those still using Subversion for revision control system for cases like managing of large files or dealing with legacy code-bases, the Apache Subversion 1.10 release is now available.

    There is quite a bit of new work in Subversion 1.10 compared to previous versions of this VCS. Highlights include improved path-based authorization with better performance and wildcard support, a new interactive conflict resolver, LZ4 compression support, new client command-line options, and experimental shelving support.

  • INN 2.6.2

    In the feature department, this release adds a new syntaxchecks parameter to inn.conf that can be used to disable message ID syntax checking, better header sanitization support in mailpost, support for TLS 1.3, and support for using GnuPG v1 (which is unfortunately important for control messages and NoCeM on Usenet still).

Qt for Python

  • Qt for Python is coming to a computer near you

    Some of you – ok, probably most of you – know that Qt is a great C++ framework, enabling developers to create magnificent user interfaces with technologies like QML, Qt Quick Controls, and Qt Widgets. I will further claim that no one is knocked out of their socks when I say that C++ is one of the most widely used programming languages in the world today. The fact that Python is one of the fastest growing programming languages, measured in popularity, is probably also old news in most communities. So, what’s this blog post all about? Well, give it two more minutes.

  • Avoid Google Maps with GNOME Maps on GNU/Linux

    So, it’s not really any secret nowadays, that Google saves pretty well anything you ever do using their services. It’s also no secret nowadays, that many people try and avoid using Google services, and would prefer to use alternatives to many of their popular tools, such as Google Maps.

    Sometimes, alternatives are available that provide similar functionality, Startpage for search or another email provider for your email needs. As far as Google Maps is concerned, it is a great product but there are alternatives available online and locally.

    GNU/Linux users have the handy GNOME Maps application at their disposal.

  • A font update

    At the end of march I spent a few days with the Inkscape team, who were so nice to come to the Red Hat Boston office for their hackfest. We discussed many things, from the GTK3 port of Inkscape, to SVG and CSS, but we also spent some time on one of my favorite topics: fonts.

  • Compiler complexities

    The other day I found myself perusing through some disassembly to get an idea of the code’s complexity. I do that occasionally because I find it the quickest way to determine if something is out of whack.

    While I was there, I noticed a rather long _get_type() function. It looked a bit long and more importantly, I only saw one exit point (retq instruction on x86_64).

  • More compiler fun

    Basically, the workaround I had at the time was to just disable -fstack-protector for the get_type() functions. It certainly made things faster, but it was a compromise. The get_type() functions can have user-provided code inserted into them via macros like G_DEFINE_TYPE_EXTENDED() and friends.

    A real solution should manage to return the performance of the hot-path back to pre-stack-protector performance without sacrificing the the protection gained by using it.

Python Distribution

  • Anaconda, CPython, PyPy, and more: Know your Python distributions

    When you choose Python for software development, you choose a large language ecosystem with a wealth of packages covering all manner of programming needs. But in addition to libraries for everything from GUI development to machine learning, you can also choose from a number of Python runtimes—and some of these runtimes may be better suited to the use case you have at hand than others.

    Here is a brief tour of the most commonly used Python distributions, from the standard implementation (CPython) to versions optimized for speed (PyPy), for special use cases (Anaconda, ActivePython), or for runtimes originally designed for entirely different languages (Jython, IronPython).

  • Fedora and Python 2

    It has been known for quite some time that Python 2 will reach its end of life in 2020—after being extended by five years from its original 2015 expiry. After that, there will be no support, bug fixes, or security patches for Python 2, at least from the Python Software Foundation and the core developers. Some distributions will need to continue to support the final Python 2 release, however, since their support windows extend past that date; the enterprise and long-term support distributions will likely be supporting it well into the 2020s and possibly beyond. But even shorter-support-cycle distributions need to consider their plan for a sweeping change of this sort—in less than two years.

    The third beta of the upcoming Qt 5.11 tool-kit release is now available and it shouldn't be much longer before the release candidate is christened.

    There may be a furth and final beta release next week, but they hope to be able to still issue a release candidate in May followed by the official Qt 5.11.0 release at the end of May. Today's third beta release clears out many bugs while still there are about one dozen bugs preventing the RC1 release. Those remaining bugs range from a QML byte code interpreter crash to the mouse area getting stuck in a pressed state on iOS.

    It’s the other way around: your manager has failed you, and is compounding the failure by conveying a destructive mindset, what’s known as a fixed mindset. To understand what I’m talking about, let’s take a quick detour into the psychology of education, and then return to those long hours you’ve been working.
