  • In a world where up is down, it's heartwarming to know Internet Explorer still tops list of web dev pain points

    Web developers resent having to deal with Microsoft Internet Explorer and Apple Safari, which they cite among their top three pain points, alongside layout and styling inconsistencies among browsers.

    This finding comes from the Mozilla Developer Network's 2020 Browser Compatibility Report [PDF], a survey of web development concerns culled from 1,429 responses out of 3,236 – the remainder having been tossed for invalid or missing data.

    The purpose of the report is to alert the browser vendors to problems so they can be addressed.

  • chemfp's chemistry toolkit I/O API

    This is part of a series of essays about working with SD files at the record and simple text level. In the last two essays I showed examples of using chemfp to process SDF records and to read two record data items. In this essay I'll introduce chemfp's chemistry toolkit I/O API, which I developed to have a consistent way to handle structure input and output when working with the OEChem, RDKit, and Open Babel toolkits.

  • Arm Begins Bringing Up Neoverse N2, Neoverse V1 Support In The GNU Toolchain

    It was just a few days ago that Arm outlined the Neoverse N2 "Perseus" design as a follow-on to the Neoverse N1 and coming concurrently to the next-generation Cortex-A. Now the company has already jumped on beginning their open-source/Linux enablement work around the Neoverse N2.

    There haven't been any Neoverse N2 additions yet to LLVM/Clang or GCC as the most interesting aspects where it would reveal any new instruction set extensions / capabilities not yet formally announced by Arm (there also isn't any patches out under review on that front either), but a patch out this morning adds Neoverse N2 support to the GNU Assembler (Gas).

  • autoconf-2.69c released [beta]
    We are pleased to announce beta release 2.69c of GNU Autoconf.
    
    This release includes two months of bug fixes since the previous beta,
    2.68b, and eight years of development work since the previous full
    release, 2.69.  See below for the list of significant changes since
    the previous beta.  See the NEWS file for a complete list of
    significant changes since 2.69.
    
    We tentatively plan to make the final release of Autoconf 2.70 at the
    end of October 2020.  Please test this beta with your autoconf
    scripts, and report any problems you find to the Savannah bug tracker:
    
       https://savannah.gnu.org/support/?func=additem&group=autoconf
    
    Please also send general comments and feedback to <autoconf@gnu.org>.
    
    Please also spread this announcement widely, so that as many Autoconf
    users as possible hear about it.
    
    Here are the compressed sources:
      https://alpha.gnu.org/gnu/autoconf/autoconf-2.69c.tar.gz   (2.0MB)
      https://alpha.gnu.org/gnu/autoconf/autoconf-2.69c.tar.xz   (1.3MB)
    
    Here are the GPG detached signatures[*]:
      https://alpha.gnu.org/gnu/autoconf/autoconf-2.69c.tar.gz.sig
      https://alpha.gnu.org/gnu/autoconf/autoconf-2.69c.tar.xz.sig
    
    Use a mirror for higher download bandwidth:
      https://www.gnu.org/order/ftp.html
    
    [*] 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 autoconf-2.69c.tar.gz.sig
    
    If that command fails because you don't have the required public key,
    then run this command to import it:
    
      gpg --keyserver keys.gnupg.net --recv-keys 384F8E68AC65B0D5
    
    and rerun the 'gpg --verify' command.
    
    This release was bootstrapped with the following tools:
      Automake 1.16.2
    
    Noteworthy changes and bug fixes since the previous beta (2.69b):
    
    * A performance regression in AC_PROG_CXX has been corrected.
      See https://savannah.gnu.org/support/index.php?110285 for details.
    
    * AC_PROG_YACC has been reverted to using ‘bison -y’.  After 2.70,
      we will instead add an AC_PROG_BISON macro for programs that
      require Bison extensions.
      See https://savannah.gnu.org/support/index.php?110266 for details.
    
    * AC_PROG_LEX no longer looks for a library providing the function
      ‘yywrap’.  LEXLIB will only be set to ‘-lfl’ or ‘-ll’ if a
      scanner that defines both ‘main’ and ‘yywrap’ itself still needs
      something else from that library.
    
      Packages should define yywrap themselves, or use %noyywrap.
    
    * When ‘$CC -E’ doesn’t run the C preprocessor, AC_PROG_CPP now looks
      in $PATH for ‘cpp’ before falling back to ‘/lib/cpp’.
    
    * AC_TYPE_PID_T now gives pid_t the correct definition on 64-bit
      native Microsoft Windows.
    
    * AC_INIT now trims extra white space from its arguments.  For instance,
    
        AC_INIT([  GNU  Hello  ], [1.0])
    
      will set PACKAGE_NAME to “GNU Hello”.
    
    * autoreconf will now run gtkdocize and intltoolize when appropriate.
    
    * autoreconf now avoids complaints from subsidiary tools about
      unknown warning categories.  For example, ‘autoreconf -Wcross’
      will no longer cause complaints from (current released versions of)
      aclocal and automake.
    
    * Generated configure scripts no longer fail catastrophically when
      stdin, stdout, or stderr is closed on startup.
    
    * Many bugs related to building Autoconf itself have been corrected.
      These mostly affected non-GNU operating systems and situations where
      optional tools are not available.
    
    * The obsolete macros AC_DIAGNOSE, AC_FATAL, AC_WARNING, and
      _AC_COMPUTE_INT are now replaced with modern equivalents by
      autoupdate.
    
    * The macro AC_OBSOLETE is obsolete.  Autoupdate will replace it with
      m4_warn([obsolete], [explanation]).  If possible, macros using
      AC_OBSOLETE should be converted to use AU_DEFUN or AU_ALIAS instead,
      which enables autoupdate to replace them, but this has to be done by
      hand and is not always possible.
    
    * AC_FC_LINE_LENGTH now documents the maximum portable length of
      "unlimited" Fortran source code lines to be 250 columns, not 254.
    
    * Warnings about obsolete constructs are now on by default.
      They can be turned off with '-Wno-obsolete'.
    
    * autoconf will now issue warnings (in the ‘syntax’ category) if the
      input file is missing a call to AC_INIT and/or AC_OUTPUT.
    
    * AC_INIT will now issue warnings (in the “syntax” category) for a
      non-literal URL argument, and for a TARNAME argument which is either
      non-literal or contains characters that should not be used in file
      names (e.g. ‘*’).

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
