lzbench 2.3

Спустя почти восемь месяцев состоялся выпуск 2.3 консольной утилиты lzbench, предназначенной для сравнения многих популярных алгоритмов компрессии и декомпрессии (их список можно получить командой lzbench -l).
Утилита написана на языках C, С++, Rust и Zig, и распространяется по лицензии GNU GPL 2 или 3 — на ваш выбор.
Изменения:

группы псевдонимов компрессоров были реорганизованы по типу — группа ALL теперь представляет собой объединение групп LZ, SYMMETRIC и MISC; кодеки BWT/PPM (bsc, bzip2, bzip3, ppmd8) перенесены в группу SYMMETRIC, а kanzi разбит по алгоритмам на отдельные уровни между группами LZ и SYMMETRIC.
добавлены псевдонимы FASTEST (все компрессоры ALL только с максимальной скоростью) и SLOW для очень медленных компрессоров (glza).
кодеки CUDA теперь по умолчанию отключены и компилируются только при указании параметра ENABLE_CUDA=1.
кодек BSC теперь обрабатывает блоки, размер которых превышает ограничение на входные данные, разбивая их на фрагменты; максимальный размер входных данных кодека — это свойство кодека, используемое при определении размера буферов;
добавлен флаг сборки -mno-strict-align и макрос SNAPPY_HAVE_RVV для RISC-V;
различные исправления для платформ x86-32 (lzham), ARM32, а также обработка размера файлов в Windows;
исправлено выделение памяти для буфера компреcсии, с учётом накладных расходов, связанных с буфером разбиения блоков кодека;

Cloudflare makes DMARC management free and generally available

Cloudflare has announced the general availability of its DMARC Management tool, providing a free solution for organizations to monitor and enforce email authentication. DMARC (Domain-based Message Authentication, Reporting and Conformance) is an email authentication protocol that lets domain owners specify in DNS how receiving mail servers should handle messages that fail SPF and DKIM checks, helping prevent spoofing and phishing. SPF (Sender Policy Framework) checks whether the sending server is allowed to send mail for the domain, and DKIM (DomainKeys Identified Mail) uses a cryptographic signature to verify that the email’s content and claimed sender domain are authentic.

OpenRouter Fusion combines multiple AI models to surpass frontier performance

OpenRouter has introduced Fusion, a tool that synthesizes outputs from multiple AI models to achieve results superior to any single model. The system functions by dispatching a prompt to a panel of participant models in parallel and using a judge model to fuse their responses. This server-side pipeline identifies consensus points, unique insights, and contradictions to produce a final, grounded answer.

Broadcom’s View: Enterprises shift AI workloads to private clouds to control costs and data

Organizations are increasingly moving productive AI workloads from public cloud environments back to private infrastructure. Recent data indicates that over half of companies now prefer private clouds for AI inference, marking a significant shift from the initial experimentation phase. This trend is largely driven by the need for better cost management, reduced complexity, and increased operational control.
