Showing an simple, flexible file handling solution in hanami, with ROM-rb ORM, using Shrine. Also contains some of my thoughts on active-storage in comparison to shrine.

Is the classical TCP congestion control mechanism known as
Nagle’s algorithm
(RFC 896 – Congestion Control) headed for the scrap heap of history?

A recent post on tech@ titled Add sysctl to disable Nagle’s algorithm (RFC 896 – Congestion Control) from Job Snijders (job@) with a patch to implement the disabling sysctl indicates that some at least think that deprecation is in order.

The message leads in,

Dear all,

Back in the early 1980s, a suggestion was put forward how to improve TCP
congestion control, also known as "Nagle's algorithm". See RFC 896.

Nagle's algorithm can cause consecutive small packets from userland
applications to be coalesced into a single TCP packet. This happens at
the cost of an increase in latency: the sender is locally queuing up
data until it either receives an acknowledgement from the remote side or
sufficient additional data piled up to send a full-sized segment.

Libtoolers!

The Libtool Team is pleased to announce the release of libtool 2.5.0, a alpha release.

GNU Libtool hides the complexity of using shared libraries behind a

consistent, portable interface. GNU Libtool ships with GNU libltdl, which

hides the complexity of loading dynamic runtime libraries (modules)

behind a consistent, portable interface.

There have been 91 commits by 29 people in the 113 weeks since 2.4.7.

See the NEWS below for a brief summary.

For a summary of changes and contributors, see:

or run this command from a git-cloned libtool directory:

Here are the SHA1 and SHA256 checksums:

  fhDMhjgj1AjsX/6kHUPDckqgiBZldXljydsL77LIecw=  libtool-2.5.0.tar.xz

Verify the base64 SHA256 checksum with cksum -a sha256 –check

from coreutils-9.2 or OpenBSD’s cksum since 2007.

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 libtool-2.5.0.tar.gz.sig

The signature should match the fingerprint of the following key:

  pub   rsa4096 2021-09-23 [SC]

        FA26 CA78 4BE1 8892 7F22  B99F 6570 EA01 146F 7354

  uid   Ileana Dumitrescu <ileanadumi95@protonmail.com>

  uid   Ileana Dumitrescu <ileanadumitrescu95@gmail.com>

If that command fails because you don’t have the required public key,

or that public key has expired, try the following commands to retrieve

or refresh it, and then rerun the ‘gpg –verify’ command.

  gpg –locate-external-key ileanadumi95@protonmail.com

  gpg –recv-keys 6570EA01146F7354

  wget -q -O- ‘https://savannah.gnu.org/project/release-gpgkeys.php?group=libtool&download=1‘ | gpg –import –

As a last resort to find the key, you can try the official GNU

keyring:

  wget -q https://ftp.gnu.org/gnu/gnu-keyring.gpg

  gpg –keyring gnu-keyring.gpg –verify libtool-2.5.0.tar.gz.sig

This release was bootstrapped with the following tools:

  Autoconf 2.72e

  Automake 1.16.5

  Gnulib v0.1-6995-g29d705ead1

NEWS

• Noteworthy changes in release 2.5.0 (2024-05-13) [alpha]

** New features:

  – Pass ‘-fdiagnostics-color’, ‘-frecord-gcc-switches’,

    ‘-fno-sanitize*’, ‘-Werror’, and ‘prefix-map’ flags.

  – Pass the ‘-no-canonical-prefixes’ linker flag.

  – Pass ‘-fopenmp=*’ for Clang to allow choosing between libgomp and

    libomp.

  – Pass ‘-shared-libsan’, ‘-static-libsan’, ‘rtlib=*’, and

    ‘unwindlib=*’ for Clang.

  – Expanded process.h inclusion on Windows for more than the

    proprietary MSVC compiler. Other alternative Windows compilers

    also require process.h.

  – Pass ‘elf32_x86_64’ and ‘elf64_x86_64’ to the linker on hurd-amd64.

  – Recognize –-windows* config triplets.

** Important incompatible changes:

  – Removed test_compile from command line options.

  – By default executables are created with the RUNPATH property for

    the Android linker. RUNPATH works for libraries which are not

    installed in system locations.

  – Removed AC_PROG_SED fallback, as the macro has been supported

    in Autoconf since the 90’s.

** Bug fixes:

  – Check for space after -l, -L, and -R linker flags.

  – Updated documentation for tests, the demo directory, and

    elsewhere.

  – Fixed Solaris 11 builds.

  – Clean trailing “/” from sysroot path.

  – Fixed shared library builds for System V.

  – Added mingw to the list of systems not requiring libm.

  – Fixed support for nios2 systems.

  – Fixed linker check for ‘–whole-archive’ support for linkers other

    than ld.

  – Use -Fe instead of -o with MSVC to avoid deprecation warnings.

  – Improved reproducibility of libtool scripts.

  – Avoided MinGW warning by adding CRTIMP.

  – Improved grep portability.

  – Fixed cross-building warnings when checking for file.

** Changes in supported systems or compilers:

  – Removed support for bitrig (–-bitrig*).

  – Added support for flang (Fortran LLVM-based) compilers.

Enjoy!

Electronic Arts has a long, storied history of trying to wring more money out of gamers after they’ve purchased a game — now, it appears, the company’s hard at work on its next generation of in-game ads. EA CEO Andrew Wilson admitted as much on the company’s Q4 earnings call: when an analyst asked about “the market opportunity for more dynamic ad insertion across more traditional AAA games,” he said the company’s already working on it. “We have teams internally in the company right now looking at how do we do very thoughtful implementations inside of our game experiences,” said Wilson. ↫ Sean Hollister at The Verge Ads in games are definitely not new – we’ve seen countless games built entirely around brands, like Tapper for Budweiser, Pepsiman, or Cool Spot for 7-Up – and banner ads and product placement in various games has been a thing for decades, too. It seems like EA wants to take this several steps further and use things like dynamic ad insertion in games, so that when you’re playing some racing game, you’ll get an ad for your local Hyundai dealer, or an ad for a gun store when you’re playing GTA in the US. Either way, it’s going to make games worse, which is perfectly in line with EA’s mission.
