  • Intel C For Metal Compiler Updated With Support For XeHP & DG1 - Phoronix

    Intel's CM Compiler is out with its first big update since earlier in the year for advancing their "C For Metal" GPU programming language effort.

    One of Intel's (open-source) GPU computing projects we don't often hear too much talk about is their C for Metal (CM) compiler. Intel C for Metal is a general purpose GPU programming language designed to provide close-to-Assembly level performance on Intel graphics hardware. C for Metal can be used for media processing and other domains at great speed. Those looking for a tutorial / sample code around CM can find Intel's documentation on

  • Dirk Eddelbuettel: RQuantLib 0.4.14: More Calendars plus Update

    A new release 0.4.14 of RQuantLib was uploaded to CRAN earlier today, and has by now been uploaded to Debian as well.

    QuantLib is a very comprehensice free/open-source library for quantitative finance; RQuantLib connects it to the R environment and language.

  • Two security improvements for GCC []

    It has often been said that the competition between the GCC and LLVM compilers is good for both of them. One place where that competition shows up is in the area of security features; if one compiler adds a way to harden programs, the other is likely to follow suit. Qing Zhao's session at the 2021 Linux Plumbers Conference told the story of how GCC successfully played catch-up for two security-related features that were of special interest to the kernel community.

  • Improvements to GCC's -fanalyzer option

    For the second year in a row, the GNU Tools Cauldron (the annual gathering of GNU toolchain developers) has been held as a dedicated track at the online Linux Plumbers Conference. For the 2021 event, that track started with a talk by David Malcolm on his work with the GCC -fanalyzer option, which provides access to a number of static-analysis features. Quite a bit has been happening with -fanalyzer and more is on the way with the upcoming GCC 12 release, including, possibly, a set of checks that have already found at least one vulnerability in the kernel.

    When GCC is invoked with -fanalyzer, it runs a module that creates an "exploded graph" combining information on the state of the program's control and data flow. That state includes an abstract representation of memory contents, known constraints on the values of variables, and information like whether the code might be running in a signal handler. The analyzer then uses this graph to try to explore all of the interesting paths through the code to see what might happen.

  • GNU Toolchain Begins Landing RISC-V Bitmanip/Zbs Instructions Support

    The GNU toolchain (initially with the GNU Assembler) has begun landing support for RISC-V's Zbs instructions that are part of the Bitmanip extension to the processor ISA.

    Zbs is part of RISC-V's Bitmanip extension, the "bit manipulation" additions to the RISC-V architecture focused on delivering code size reduction, better performance, and lower energy consumption. The 1.0 Bitmanip extension was frozen this summer and thus now moving on to compiler/toolchain support. More details on Bitmanip and the specific Zbs instructions via this repository.

  • Qt for Python release: 6.2 is here!

    We are really happy to tell you that following the Qt release, Qt for Python is also available!

    Many things happened on this release, we decided to communicate a little more on the details of the major milestones that we achieved on this release.

    You might have notice that last week only the Windows wheels are available on PyPi, that was due to the wheel size increase from the new modules, but luckily the PyPi team managed to address this quickly.

  • Excellent Free Tutorials to Learn Nim - LinuxLinks

    Nim is a statically typed compiled systems programming language. It combines successful concepts from mature languages like Python, Ada and Modula. The syntax of Nim resembles that of Python.

    It is designed to be “efficient, expressive, and elegant” supporting metaprogramming, functional, message passing, procedural, and object-oriented programming styles by providing several features such as compile time code generation, algebraic data types, a foreign function interface (FFI) with C, C++, Objective-C, and JavaScript, and supporting compiling to those same languages.

    The compiler and the standard library are licensed under the MIT license.

  • BBC Micro:bit Reads Morse Code With MakeCode | Hackaday

    We always have mixed feelings about the drag-and-drop programming languages. But we were impressed with [SirDan’s] Morse code decoder built with the graphical MakeCode. Granted, it is reading 5 element groups from a button on the BBC micro:bit and not worrying about details such as intercharacter or interelement spacing or word spacing. But it is still a nice demo for MakeCode.

  • My Favorite Warnings — A Belated Introduction | Tom Wyant []

    A couple installments into this series of blog posts, I realized an introduction to Perl warnings would be appropriate, with some words on how to turn them off, and why you probably do not want to. Yes, this should have been the first post in the series, but I didn't know it would actually be a series, and, well, maybe better late than never.

    The Perl compiler/interpreter can emit warnings when it finds things that may indicate a problem with the code. These are not (yet) enabled by default, but experience has shown that enabling them can highlight conceptual and logic errors.

    Back in the early days of Perl 5, these were enabled using the -w command-line option, or by setting the $^W variable to a true value. But this mechanism had two drawbacks: it was all-or nothing, and it was global in scope. Certainly the value of $^W could be localized, but localization does not prevent a called module from seeing changes made by its caller.

  • Dyn async traits, part 4

    In the previous post, I talked about how we could write our own impl Iterator for dyn Iterator by adding a few primitives. In this post, I want to look at what it would take to extend that to an async iterator trait. As before, I am interested in exploring the “core capabilities” that would be needed to make everything work.

  • Check Java processes on Linux with the jps command |

    On Linux, there are commands to view processes running on your system. A process is any ongoing event being managed by the kernel. A process is spawned when you launch an application, but there are also many other processes running in the background of your computer, including programs to keep your system time accurate, to monitor for new filesystems, to index files, and more. The utilities, such as those included in the procps-ng package, that monitor these processes tend to be intentionally generic. They look at all processes on your computer so you can filter the list based on what you need to know.

    On Linux, you can view processes with the ps command. It is the simplest way to view the running processes on your system.

  • How to remove special characters using sed

    Sed command is a Linux utility that can be used to perform lot of operations that includes insert and delete operations, find/search and replace operations. The sed command allows Linux users to edit and apply several functions on files without opening them directly. The sed command support editing functionalities that vary from beginners’ level to advanced level: For instance, inside a text file these operations can be performed on several datatypes: characters, numeric, special characters, alphanumeric et.,

    Keeping in view the importance of sed command; our today’s guide will explore several ways to remove special characters using sed command in Ubuntu.

  • How to use sed character classes

    Stream Editor (sed) is known as a powerful editor because of its wide range of supported functionalities like substituting, editing, deleting and many more. While Stream Editor has the long list of characters that provide assistance to manage the files automatically: these characters are enclosed in a set of similar characters known as Character Classes; these classes contain the characters of alike families.

    For instance, the digits while using sed are accessed through [[:digit:]] class and the alphanumeric characters are stored in the class named as [[:alnum:]]. Similarly, all the characters belong to some specific character class; knowing the importance of these classes, our today’s guide is focused to provide a deep insight into character classes in sed.

  • Bash Associative Array Explained With Examples In Linux - OSTechNix

    This is the second article as part of bash arrays. In the previous article, we have discussed how to work with Indexed arrays in Bash. In this guide, we will discuss about Bash Associative Array in detail with examples in Linux.

    Associative arrays work based on key-value pairs. In some languages, it is also called dictionaries or hash maps. The main difference between Indexed and Associative arrays is, Indexed arrays works based on index value, and each element in the array is mapped to a particular index position of the array. An associative array uses a "key" to map the value instead of index positions.

  • How to open URL in python

    Python is an interpreted language; it has different libraries to perform various functions. A Uniform Resource Locator (URL) is actually a web address to open a specific site. Sometimes while working in python we need to fetch data from a website, for this we have to open the url of a specific website. So, to open a URL in python we need to import the specified module and perform some steps to open that URL. In this article we will discuss how to open a URL in Python using “urllib.request” and “webbrowser” modules on Ubuntu (Linux OS) through a defined procedure.

  • How to use Python readline() function

    There are many useful methods of Python which we can use in our programs. One of the handy methods is python readline() method, it reads one complete line from a specified file at a time by default. You can also read more than one line or complete file using readline() method using different conditions like using size argument. The readline() method inserts a new line (\n) at the end of returned String.

    In this Article we discussed the usage of the readline() method in python and how to run it on a Linux system.

  • How to Rename File in Python

    We can rename files in Linux terminal using different approaches, one of the approaches is using Python which is discussed in this article. We cannot write Python code directly on the terminal, we create a separate file in a text editor. The “rename” is one of the operating system functions so we will use a Python OS module for this purpose.

  • How to Remove Characters from Strings in JavaScript

    JavaScript provides users with various methods and properties for string manipulation, to transform those strings or to search useful information from those strings. Sometimes we have various lines of code in which we need to make changes, search for a character or replace a character or remove a character from a string.

    All these tasks become difficult to do and hence methods are provided by JavaScript that makes the job easier. Users can easily use these methods to manipulate a string and transform it. In this article we’ll discuss how to remove characters from strings in JavaScript, various ways and methods provided by JavaScript along with examples for your better understanding.

  • How to remove white empty spaces from Strings in JavaScript

    Manipulating string is a useful task while programming as it helps us in finding words, replacing words and especially for removing white spaces from string. JavaScript provides various built-in methods to users for manipulating with strings.

    Removing whitespaces from a string can be complex when it comes to tabs and line breaks and while you’re working with various lines of codes but JavaScript provides users with methods through which it becomes easier to manipulate strings and remove whitespaces from them and that’s why in this article we’ll discuss different methods and ways to remove whitespaces from a string in JavaScript, their explanation and how they’re used along with examples.

  • How to use git stash and git stash pop commands

    Git helps to control the version of your projects. Git is a well-known software used by programmers to work in a collaborative manner to achieve specific goals. The Git repositories are hosted by GitHub that helps to work online and assist the programmers to share their project or code files there. Moreover, Git is backed up by several operations or commands also like Git stash, Git stash apply, Git stash pop, Git stash drop. Inspired by the importance of Git, today’s guide will provide fundamental information about Git stash and Git stash pop; and use of both commands/operations in Ubuntu.

  • How to remove git remote

    Git is an open-source software with version control support that allows the users to store, edit and track the changes of projects.

    There are various benefits in using Git that include: fast and efficient processing on shared projects as well as monitoring the security of the projects. However, one of the major reasons for the emergence of Git is the remote repository access; the Git remote repository is available on the server and multiple contributors can make changes to it. Users can clone the remote repository to their machines and can retrieve required information from Git repository locally or it can help to do experimental analysis on the files of the repository without affecting its originality on the server. This cloning phenomenon allows to establish the connection between git remote repository and local repository; moreover, it also supports creating several clones of a single git repository so that multiple stakeholders can get access to the same project and can-do changes parallelly. The terminal support of Ubuntu can be used to add or remove the remote repositories as your local one.

  • How to make git local same as remote

    Git support of managing local and remote repositories has contributed to making computing a better experience. The remote repositories are managed on the server, whereas local repos are maintained on the machine and can be accessed without internet availability. Git offers two streaming supports: one is upstream, and the other is downstream; the upstream refers to where you clone your rep, and downstream allows you to integrate your work with other works.

    As Git is distributed version control software, working in a parallel manner may acquire the confusion state as there are several contributors making changes on a single project. Thus, it is recommended that the remote and local repositories must be synchronized to avoid any mishaps like you may require to fall back to some previous versions, which can be budget and time-consuming.

    While working in an environment where sometimes you have to make changes on remote, and you want that same changes must be present on your local repository as well. Keeping in view the importance of synchronization, we have prepared this guide to demonstrate the steps of keeping the local repository the same as remote...

  • How to output git log with first line only

    Git is one of the well-known repositories for version control systems and used widely among programmers to keep an eye on the changes being performed regularly. Sometimes, it is observed that fetching the history does not fulfill the purpose of it; so, you need to filter the content accordingly. Git provides this facility with its git log command; git log is used to display the content from history by filtering it according to the options provided.

    If you have a long list of commits and you want just basic information about commits; then the git log command provides a one line display of every commit. We have prepared this post to demonstrate the usage of git log command to get the output of commit in one line only: Let’s start this guide from general usage of git log followed by our targeted area:

  • Auto-Accepting in QSortFilterProxyModel

    In Qt 5.10, we added support for recursive filtering in QSortFilterProxyModel, which means keeping all parents of items matching the filter.

    One of the comments in the blog post about that feature was “Sometimes, you do not only want to show parents for a match (so the match is visible), you may (also) want to show children for a match”. This is indeed something I saw a need for, more than once. For instance, you filter a large tree for a project name but then you want to see all sub-tasks of that project as well, rather than see only those that contain the project name while those that do not are hidden.

Raspberry Pi Plots World Wide Earthquakes

Filed under

What do you do when you stumble across a website posting real-time earthquake data? Well, if you’re [Craig Lindley] you write some code to format it nicely onto a display, put it in a box, and watch it whilst making dinner.

[Craig] started off with coding in Forth on the ESP32, using ESP32Forth, but admits it didn’t go so well, ditching the ESP32 for a Raspberry Pi 3 he had lying around, and after a brief detour via C++, he settled on a Python implementation using Pygame.

A case was 3D printed, which he says worked OK, but needs a little tuning to be perfect. There is no shortage of casing options for the Pi with the official 7″ display, [Craig] suggests that it probably wasn’t worth the effort to 3D print the case and if he was building it again would likely use a commercially available option which had a better fit.

  • Steinar H. Gunderson: plocate 1.1.12 released

    plocate 1.1.12 has been released, with some minor bugfixes and a minor new option.

    More interesting is that plocate is now one year old! plocate 1.0.0 was released October 11th, 2020, so I'm maybe getting a bit ahead of myself, but it feels like a good milestone. I haven't really achieved my goal of being in the default Debian install, simply because there is too much resistance to having a default locate at all, but it's now hit most major distributions (thanks to a host of packagers) and has largely supplanted mlocate in general.

  • Dirk Eddelbuettel: littler 0.3.14: Updates

    The fifteenth release of littler as a CRAN package just landed, following in the now fifteen year history (!!) as a package started by Jeff in 2006, and joined by me a few weeks later.

    littler is the first command-line interface for R as it predates Rscript. It allows for piping as well for shebang scripting via #!, uses command-line arguments more consistently and still starts faster. It also always loaded the methods package which Rscript only started to do in recent years.

  • Current issue : #70 | Release date : 2021-10-05

    Phrack! We're back! It was only five years ago that issue 0x45 was released. It may sound bad, but it is also, indeed, quite bad. Issue 0x45 was released four years after issue 0x44. And we are now five years after that. Just trying to set the context here. The world is so different and so many things have happened in these five years that it makes no sense trying to make any point. Phrack has always been a reflection of the hacking community, and guess what, the community is moving away from itself. By this we don't mean that there are no talented hackers, because there most definitely are (just take a look at our authors). We also don't mean that there is no exquisite public hacking, because there is (again, our articles as proof). However, there is a clear move away from the collective hacking mindset that was most prevalent in the past. The word "scene" brings only smirks to people's faces. There are many reasons for this, and we are all to blame [1].

    So where is the community right now, and, most importantly, where is it going?

  • LAMP is dead! Long live (Perl) web frameworks!

    Certainly on the Perl side (with which I’m most familiar), the community has long since recommend­ed the use of a framework built on the PSGI specification, deprecating 1990s-era CGI scripts and the mod​perl Apache extension. Although general-purpose web servers like Apache or Nginx may be part of an overall system, they’re typically used as proxies or load bal­ancers for Perl-specific servers either provided by the framework or a third-party module.

  • How to create a linked list in C

    Linked List is another linear data type, e.g., structure data type, widely used in the C language. The main concept in the linked list is storing and binding the locations of data by Pointers. Let see how we will create a Linked list in C language by using Ubuntu 20.04 system. For that, open up the console application from the search area of the Linux desktop. On the other way, you can utilize the shortcut “Ctrl+Alt+T”.

  • Semctl System Call in C

    The C language comes up with the semctl system call in the Linux system. This system call has been widely used in the Linux system to carry out the control processes specified by the console shell on some particular semaphore set. The semaphores are known IPs widely used to give access to processes for communication with one another. Semaphore can be a variable having abstract data type for the control access of 1 resource for many procedures. Hence, the semctl system call has been used here to control the semaphore set. Let’s start by signing up from the Linux system.

    Open the console application from the search area. A quick alternative way to open the console is via “Ctrl+Alt+T”.

  • Waitpid Syscall in C

    The waitpid() system call monitors a child of the caller process for state changes and retrieves information about the child whose behavior has changed. The child was halted by a signal or resumed by a signal regarded as a state shift. Waiting for a terminated child enables the system to free the resources associated with the child; if no wait is conducted, the terminated child will remain in a “zombie” condition.

    The waitpid() system function pauses the current process until the PID argument specifies a child who has changed. The calling process is paused until a child’s process completes or is terminated. Waitpid() halts the calling process till the system receives information about the child’s status. Waitpid() returns quickly if the system already has status information on a suitable child when it is called. If the caller process gets a signal with the action of either executing a signal handler or terminating the process, waitpid() is terminated. The waitpid() function will pause the caller thread’s execution until it receives information and updates for one of its terminated child processes or a signal that will either run a signal-catching procedure or terminate the process.

  • Shift Operators in C

    In general, you should not need to worry about operations somewhere at bit level as a developer. You can conceptualize in terms of bytes, int, and doubles, and even higher-level data. However, there are instances when you would like to zoom in on a single piece. The bits in an integer variable are shifted by a defined number of positions using two shift operators. The “>>” operator changes bits to the right, while the operator changes bits left. In general, employing the left and right shift operators instead of computing and then multiplication by a power of two will result in substantially faster code.

  • Puts function in C

    Displaying the output on the screen is an important component of every programming language. The puts function in C is used to perform this. The puts () call in C is a file handling method that is utilized to print a line to the output screen. The puts () function looks a lot like the printf() function. The puts () function is being used to display the string that was read previously using the gets () or scanf() functions on the terminal. The integer value returned by the puts () function represents the number of characters written on the terminal.

    If the string contains formatting characters such as ‘% s,’ printf() will provide unpredictable results in the puts() function. Also, if “str” is a user-supplied string, using printf() could compromise security.

  • How to Use Dataclasses in Python

    This article will cover a guide on using the new “dataclass” objects included in Python 3.7 and newer versions. Dataclasses are just like other Python classes, but they are especially designed to be used as data containers and provide a cleaner and shorter syntax for quickly creating data objects. If you know about “namedtuple” objects and have used them in Python, you can define them as mutable namedtuple type objects. You can create new instances of dataclasses like any other class or namedtuple type objects and access their attributes using dot notation.

  • How to Use New F Strings in Python

    This article will cover a guide on using the new “F” type string formatting syntax added to recent versions of Python. Simply termed as “f-strings” or “formatted string literals”, these expressions allow you to use Python variables, functions and statements directly in the text of a string. They also help in keeping the code clean, as you can use inline expressions without resorting to any kind of ordered substitutions that are usually part of the other string formatting techniques available in Python. F-strings are included by default in Python 3.6 and newer builds.

  • Command Line Arguments

    In many cases, bash scripts require argument values to provide input options to the script. You can handle command-line arguments in a bash script in two ways. One is by using argument variables, and another is by using the getopts function. How you can handle command-line arguments is shown in this tutorial.

  • How do I list all schemas in PostgreSQL?

    Postgresql is a rational and reliable database. Many features of PostgreSQL differentiate it from other databases. PostgreSQL schema is a property that allows the user to maintain and organize the objects in the current database and manage them in logical groups. The currently existing schemas are viewed in the psql and pgAdmin as well. To enlist all the schemas in PostgreSQL, there are many approaches. We have used mainly of them to explain in this article. To understand this dilemma, you need to follow some prerequisites steps like:

    Install PostgreSQL on your system and configure it. After successful installation and the configuration of Postgresql, confirm it by checking its version on the psql. When you have installed the database, now you can use it because you have privileges to access the features present in it. If you have some knowledge of databases, then it will be favorable for you to understand the schemas. Now open psql and apply the password for the user for the server connectivity.

  • Change column name Postgresql

    In PostgreSQL, while performing operations, you need to create relations. After the creation of the tables, you may want to edit the attributes you have provided. One of the examples is to modify the column name of the table. The column name can be changed in PostgreSQL by using the “ALTER” command on the table.
    First, we provide the table name and then the column name after the rename clause. Thirdly, the name that is to be placed is written.

  • Using Floating Data Types in PostgreSQL

    PostgreSQL supports multiple different data types. One such data type is the floating data type which is used to store the floating-point data. We all understand that the handling and manipulation of this particular data type is a bit tricky and complex, so the programmers find it a little difficult to use it. Therefore, in this guide, we have decided to share the method of using the floating data types in PostgreSQL in Windows 10 after sharing with you a brief introduction of this data type.

  • Postgresql temporary tables

    As the name indicates, PostgreSQL temporary tables are the tables that are created for some time and are removed manually or automatically. Manually removal deals with deleting the table. Whereas the table is automatically removed when the database session is ended. The temporary tables last till the session exists.

    The use of a temporary table helps in avoiding the overloading of data in a particular database. Whenever you think you need to enter data in a database for some time to perform operations on the data, you will go for the temporary table. So that after usage, they are removed. And your database will have sufficient free space. This tutorial will explore what a temporary table is, its working, and its usage.

  • A Lasting Legacy: Thoughts on COBOL

    Today, COBOL is usually either the butt of cruel jokes or a mythical concept in programmer lore, the story usually being that a COBOL guru is rushed in by a massive corporation to write a few lines of program code in exchange for tremendous amounts of money, saving the world from a bug that's just been waiting to happen since some time in 1967. Unlike many other old languages like Assembler, LISP, C, BASIC and Pascal, COBOL seems to stand for itself in discussions about software development. To many developers, it's an afterthought - so much so that when Jonathan Blow cooks up doomsday scenarios, it's a fictional lack of C programmers that threatens civilization rather than most IT professionals' complete disinterest in COBOL - the language that runs both their bank accounts and their airline bookings to Very Important Conferences.

    That’s the purpose of functions, they’re pieces of code only defined once for a particular task and come with reusable functionality so that users can call them whenever they want to perform a task. This makes your program understandable and debugging easier.

    Sometimes functions require some input and sometimes they may or may not return some value, but all of these vary from function to function and the task assigned to that specific function. In Python, functions are essential parts that may be user-defined or built-in. In this article, we’ll discuss functions in Python, types of functions, how to define them along examples for your better understanding.

  • Check out the new LibreOffice Development Blog!

    Here on The Document Foundation’s blog, we post about general news and activities in the LibreOffice world. But now we have a dedicated development blog, set up by Hossein Nourikhah, who recently joined us as a Developer Community Architect.

  • LibreOffice Development blog has started! - LibreOffice Development Blog

    To know more about what is going on in LibreOffice, you can refer to the main Document Foundation blog. Also, if you want to learn more about the LibreOffice design, you can refer to the LibreOffice Design Team blog. And now, we have created a new blog, dedicated to the LibreOffice development!

  • Getting Started (Video Tutorial) - LibreOffice Development Blog

    LibreOffice development starts with setting up a development environment. After that, you can do the development in your favorite IDE. In this 80 minutes presentation, you will find everything you need to know to get started with LibreOffice development; from installing dependencies using distribution tools, LODE (LibreOffice Development Environment) or manual setup to compilation itself.

    With this tutorial, you can build LibreOffice for yourself. Then we look at some simple tasks from LibreOffice EasyHacks. After that, you can try to get your submission merged into the LibreOffice code by submitting it to gerrit, and doing the fixes requested by the reviewers.

How To Use The Raspberry Pi Sense HAT

Filed under

The Astro Pi project sees experiments, written by school children running on real Raspberry Pis. This might not seem very exciting until you hear where those Raspberry Pis are located, the International Space Station, in orbit high above the Earth.

Launched, literally, in December 2015 via the Principia mission, Astro Pi began when UK astronaut Sir Tim Peake took two Raspberry Pi B+, Pi cameras and Sense HAT add-on boards enclosed in aluminum chassis designed to manage the Raspberry Pi thermals to the ISS. The two Astro Pi computers, affectionately named Izzy and Ed were able to measure temperatures, humidity, air pressure, orientation and acceleration forces thanks to the Sense HATs plethora of onboard sensors. These two Raspberry Pi were used in multiple experiments since 2015, but the B+ models inside were getting a bit long in the tooth.

Filed under
This is to announce automake-1.16.5, a stable release.

Thanks to Karl for doing all the real work.
See the NEWS below for a brief summary.

There have been 18 commits by 6 people in the 10 weeks since 1.16.4.

See the NEWS below for a brief summary.

Thanks to everyone who has contributed!
The following people contributed changes to this release:

  Akim Demaille (1)
  Dimitri Papadopoulos (1)
  Jan Engelhardt (1)
  Jim Meyering (6)
  Karl Berry (8)
  Nick Bowler (1)

Jim [on behalf of the automake maintainers]

Here is the GNU automake home page:

Here are the compressed sources: (1.6MB) (2.3MB)

Here are the GPG detached signatures[*]:

Use a mirror for higher download bandwidth:

Here are the SHA1 and SHA256 checksums:

8B1YzW2dd/vcqetLvV6tGYgij9tz1veiAfX41rEYtGk  automake-1.16.5.tar.xz
B70krQimS8FyUM4J7FbpIdY0OQOUPpnM9ju/BwXjRgU  automake-1.16.5.tar.gz

Each SHA256 checksum is base64 encoded, instead of the
hexadecimal encoding that most checksum tools default to.

[*] Use a .sig file to verify that the corresponding file (without the
.sig suffix) is intact.  First, be sure to download both the .sig file
and the corresponding tarball.  Then, run a command like this:

  gpg --verify automake-1.16.5.tar.xz.sig

If that command fails because you don't have the required public key,
then run this command to import it:

  gpg --keyserver --recv-keys 7FD9FCCB000BEEEE

and rerun the 'gpg --verify' command.

Please report bugs and problems to <>,
and send general comments and feedback to <>.


* Bugs fixed

  - PYTHON_PREFIX and PYTHON_EXEC_PREFIX are now set according to
    Python's sys.* values only if the new configure option
    --with-python-sys-prefix is specified. Otherwise, GNU default values
    are used, as in the past. (The change in 1.16.3 was too incompatible.)

  - consistently depend on install-libLTLIBRARIES.

* Distribution

  - use const for yyerror declaration in bison/yacc tests.
