  • GDB Debugger Adds Support For Debuginfod Web Server

    Debuginfod is the Red Hat led debug information HTTP web server distributed as part of elfutils and able to supply on-demand source code and ELF/DWARF debug files to debuggers / IDEs / other compiler tooling. The GDB debugger can now tap debuginfod for on-demand source files and debug information that isn't present on the local system.

    The motivation with debuginfod is to carry less developer "baggage" on local systems when it comes to debug files and potentially even source files. Particularly for organizations or cases like Linux distributions, a centralized debuginfod server could in turn supply the needed files to clients based upon the requested build ID. Red Hat has been working to expand the debuginfod support both for the GNU toolchain and also LLVM, among other possible users.

  • When is GOTS not in the national interest?

    The modern open-source software (OSS) movement can be traced back to the early 1980s with the birth of Richard Stallman’s GNU Project and the Free Software Foundation.

    [...]

    However, cost is a red herring for the real challenge presented by GOTS software solutions. On the surface, GOTS seems very similar to OSS which implies that it has the larger structural advantages of OSS. If handled cautiously, it can have those advantages, but care needs to be taken about what sort of existing software is being commoditized. The U.S. has a national interest in maintaining a strong software development capability. We are fortunate to be the dominant software-building country in the world. According to the Forbes 2000 list, the total market capitalization of U.S. internet, software, and computer services companies is close to $4.7 trillion — more than twice the rest of the world combined. Software tech is an enormous comparative advantage for the U.S. As a result, it is clearly in the national interest to have the government avoid directly competing against and potentially weakening the U.S. private sector.

  • New compiler added to popular studio for ARM and Cortex-M IDE

    The studio for ARM/Cortex-M is now supplied with three different compilers: GCC, Clang and the company's own compiler. The new compiler outperforms GCC and regular Clang on most benchmarks, decreasing both size of generated code as well as its execution speed.

  • Cosmic Python

    Folks I've written a new book! Along with my coauthor Bob, we are proud to release "Architecture Patterns with Python", which you can find out more about at cosmicpython.com. The cosmic soubriquet is a little joke, Cosmos being the opposite of Chaos in ancient Greek, so we want to propose patterns to minimise chaos in your applications.

  • PyCharm: Smart execution of R code

    In this release, we also introduced some stability improvements and enhancements for resolving and autocompleting named arguments.

  • Return Multiple Values from A Python Function

    The function is used in any programming language to run a specific block of code multiple times when require and organize the code properly. Sometimes, this requires reading the return value from the function for the programming purposes. The return value of the function is stored in a variable. Python functions can return both single and multiple values. This tutorial shows how multiple values can be returned from Python functions with multiple variables, objects, tuples, lists, and dictionaries.

  • Reading and Writing Excel (XLSX) Files in Python with the Pandas Library

    Just like with all other types of files, you can use the Pandas library to read and write Excel files using Python as well. In this short tutorial, we are going to discuss how to read and write Excel files via DataFrames. In addition to simple reading and writing, we will also learn how to write multiple DataFrames into an Excel file, how to read specific rows and columns from a spreadsheet, and how to name single and multiple sheets within a file before doing anything.

  • Writing the Factorial Program in Python

    The factorial of a number is the number that you get after multiplying all numbers from 1 to that number. The factorial of a number is denoted by the ‘!’ symbol. For example, if we want to find out the factorial of 4, denoted 4!, then the result would be 1x2x3x4 = 24. There are many ways to find out the factorial of a number. The factorial can be determined in Python using the built-in function for loop and recursive functions. This tutorial shows how the factorial of a number can be determined using various functions of Python.

  • How to Use Boxplot in Python

    A box plot is used to summarize data sets by using the box and whisker plot method. This function helps users to understand the data summary properly. Box plots can be very useful when we want to know how the data is distributed and spread. Three types of quartiles are used in the box plot to plot the data. These values include the median, maximum, minimum, upper-quartile, and lower-quartile statistical values. A box plot summarizes this data in the 25th, 50th, and 75th percentiles. This tutorial will show you how to create box plots based on a given data set using the pandas and seaborn libraries of Python.

  • How to Use Urllib in Python

    Python contains a module named urllib for handling Uniform Resource Locator (URL)-related tasks. This module is installed in Python 3 by default, and fetches URLs of different protocols via the urlopen() function. Urllib can be used for many purposes, such as reading website content, making HTTP and HTTPS requests, sending request headers, and retrieving response headers. The urllib module contains many other modules for working with URLs, such as urllib.request, urllib.parse, and urllib.error, among others. This tutorial will show you how to use the Urllib module in Python.

Bifrost meets GNOME: Onward & upward to zero graphics blobs

In our last blog update for Panfrost, the free and open-source graphics driver for modern Mali GPUs, we announced initial support for the Bifrost architecture. We have since extended this support to all major features of OpenGL ES 2.0 and even some features of desktop OpenGL 2.1. With only free software, a Mali G31 chip can now run Wayland compositors with zero-copy graphics, including GNOME 3. We can run every scene in glmark2-es2, and 3D games like Neverball can be played. In addition, we can support hardware-accelerated video players mpv and Kodi. Screenshots above are from a Mali G31 board running Panfrost. All of the above is included in upstream Mesa with no out-of-tree patches required, with the upcoming Bifrost support enabled via the PAN_MESA_DEBUG=bifrost environmental variable.

  • Steal everything and flee from the Burning Knight - out now

    With some great lighting work, furious action and a good sprinkle of comedy Burning Knight is an fast-paced roguelike that's out now. Note: key provided by the developer. It's…ridiculous. I mean that in the nicest way I can because I'm at a loss for a better word. The whole game is just pure madness and a massive amount of fun. Much like other similar titles that came before including Nuclear Throne and Enter the Gungeon, it's got that supremely satisfying gameplay loop nailed down perfectly. Run through various floors as you dodge roll, shoot and slice your way through everything. [...] Hilariously, the shop is clearly selling dubious wares just take a look at the shopkeeper and tell me that's not a robber, just look at the mask! You can even start a fight with them, much to my surprise when accidentally clicking next to them and they asked me to stop. So for science, I hit them a few more times and they got very angry and starting running around super fast, firing everywhere. Even though I had clearly done it to myself, it was a bit of a shock but super funny especially with the Burning Knight cheering them on against me.

  • Valve moves the Steam Game Festival to June 16

    The upcoming Steam Game Festival Summer Edition has been delayed, as confirmed in a Valve email today. Originally due from June 9 - 15, they've now moved it to June 16 - 22. No reason was given and their email on it was extremely brief. It's not really unexpected though at this point, practically every other major event has also been postponed. This is all in response to the ongoing situation in America right now, after the death of George Floyd who died at hands of Minneapolis police officers.
