  • KDE e.V. AGM at Akademy

    The Annual General Meeting (AGM) of KDE e.V., the association that supports the KDE community financially and organizationally, has been announced. As usual, it takes place at Akademy – online again this year, and the AGM is on monday june 21st, the longest day in the northern hemisphere – and will hopefully consist of quick and boring financial stuff, followed by a spirited discussion on the goals and activities and working groups of the e.V.

  • AlpineConf 2021 server is UP
    You are hereby invited to attend AlpineConf 2021, as the server is up. 
    The conference itself will be running May 15th and 16th starting at 10 am 
    CEST / 4 am EST and ending whenever it ends each day.
    
    
    
    
    I apologize for the delay in finishing the setup of this, the last week 
    was a bit hectic and then last weekend my bank decided that they needed to 
    go break everybody's accounts for no reason, so I spent the time I was 
    going to spend finalizing this infrastructure on hold with my bank 
    instead...
    
    
    
    
    Tomorrow and throughout the week we will be doing various test runs.  If 
    you're presenting a talk at AlpineConf and you want to experiment with the 
    BigBlueButton platform, there is a Sandbox room, ask me for the link in 
    IRC.
    
    
    
    
    We will likely do a meeting amongst presenters either tomorrow or on 
    Wednesday to lock in what the schedule will look like.  If you haven't 
    recorded your talk, do so and then attach a link to the video in the issue 
    tracker item for your talk.  You can host it on your own server or on 
    YouTube, Vimeo or DailyMotion.  Note that due to the way BigBlueButton 
    works, each viewer will fetch the talk video themselves, so it may make 
    sense to host it on YouTube or similar.

Programming Leftovers

  • The PyCon Italia 2022 multiplicity

    The common thread in all these years of participation was not so much the Python language as the people I met and the community of which I felt more and more part, which is why the 2022 edition of PyCon Italia was special because it allowed me to resume this tradition in the presence after two years of interruption.

    This year I experienced PyCon Italia from multiple points of view, from which I will try to tell you about my conference, I am sure that you will recognize yourself in one of them and that you will want to participate in a new role, and I hope you will participate in the next edition of PyCon Italia becoming part of the great Italian Python community.

  • [Release] Status of Python 3.11 release

    We may be pushing the final release until December if the stability of Python 3.11 doesn't improve.

  • Announcing perlcritic Policy ValuesAndExpressions::ProhibitFiletest_rwxRWX

    Since several places in the Perl documentation caution against the use of the file access operators (-r and friends), and since I was unable to find a Perl::Critic policy dealing with this, I thought I would make one: Perl::Critic::Policy::ValuesAndExpressions::ProhibitFiletest_rwxRWX. This policy is assigned to the 'bugs' theme. It has low severity because there are some uses of these operators that seem legitimate to me -- or at least I see no easy way to get around their use.

  • [Old] Five Tips to Writing RISC-V Assembly

    Writing assembly is itself an art. When C, C++, or any other language is compiled, the compiler determines the art of writing assembly. However, this time, we will some of the techniques and decisions we can make to write these ourselves.

    We will use RISC-V to see how to design logic, write up the logic, and translate the logic into assembly.

  • libmagic: The Blathering

    The libmagic library is older than over half of the human population of Earth, yet it is still in active development and is in the 99.9th percentile of most frequently installed Ubuntu packages. The library’s ongoing development is not strictly limited to bug fixes and support for matching new file formats; the library frequently receives breaking changes that add new core features to its matching engine. libmagic has a custom domain specific language (DSL) for specifying file format patterns. Run `man 5 magic` to read its documentation. The program compiles its DSL database of file format patterns into a single definition file that is typically installed to /usr/share/file/magic.mgc. libmagic is written in C and includes several manually written parsers to identify various file types that would otherwise be difficult to represent in its DSL (for example, JSON and CSV). Unsurprisingly, these parsers have led to a number of memory safety bugs and numerous CVEs.

  • IAR Systems enable innovation in Automotive, providing full support for Renesas RH850 - TechNode Global

    The IAR Embedded Workbench for RH850 and IAR Build Tools for RH850 have been upgraded to the latest technology platforms, including the latest C/C++ language (library support for the C++17 language standard), which will allow developers to build far more advanced code to handle more complex tasks.

  • Passing an Object as a Parameter | Adam Young's Web Log

    I think there area couple of competing guidelines here: Don’t Repeat Yourself versus Let the Complexity Emerge. But let’s start with your previous article on Naive Implementations. The very first implementation should be Naive, changing as little code as possible. As such, the example at the start where you pull the initials out in the calling location is possibly the right one. It does, however, split the logic up to two places, so it might even be easier to pass the whole object in, and pull the initials out in the display code. This could get into a discussion of model-view-controller approach. Are the initials part of the model or part of the view? Here is where we let the complexity emerge. If it is only ever used in this one location, you can think of it as part of the view. If the initials get any wider use, they start migrating toward the model. Thus, I would need more context before I could say what the right design is for them.

  • Cybersecurity experts question Microsoft's Ukraine report

    Microsoft President Brad Smith spent much of last Wednesday traveling across Washington to promote his company’s sweeping report on the current state of cyberwarfare and disinformation in the Russia-Ukraine war.

    He sat down with David Ignatius, foreign affairs columnist for The Washington Post, for a webcast on its findings. Afterwards, he headed to the Reagan Institute’s Center for Freedom and Democracy to give a 20-minute speech about the 27-page report called “Defending Ukraine: Early Lessons from the Cyber War” before joining Senator Angus King (I-ME) for a panel discussion.

    The New York Times, CNN, The Washington Post, NPR and others covered the study as an accurate and revealing look at an otherwise opaque and confusing digital front in the Ukraine war.
