SQLite 3.45 Released With JSON Functions Adapted To Use JSONB - Phoronix
SQLite 3.45 Released With JSON Functions Adapted To Use JSONB Written by Michael Larabel in Programming on 15 January 2024 at 03:05 PM EST. 6 Comments SQLite 3.45 was released today with the SQLITE_DIRECT_OVERFLOW_READ optimization being enabled by default that can help for apps relying on SQLite and doing a lot of reads of large BLOBs or strings deliver better read performance. There are also que
Redis Renamed to Redict Redict was originally created by Salvatore Sanfilippo under the name "Redis". Around 2018 he started losing interest in the project to pursue a science fiction career and gave stewardship of the project to Redis Labs. I think that was an unfortunate move because their goal is mainly to extract profit from the software project rather than to uphold the ideals of Free and Ope
Linux 6.9 Deprecates The EXT2 File-System Driver - Phoronix
Linux 6.9 Deprecates The EXT2 File-System Driver Written by Michael Larabel in Linux Storage on 26 March 2024 at 09:20 AM EDT. 49 Comments While Linux 6.9 brings many great changes and new features / hardware support, on the deprecation side it's deprecating the classic EXT2 file-system driver. The EXT2 file-system has been around for thirty years, it's been over two decades since EXT3 and a decad
Linus Torvaldsは9月15日、「Linux 6.11」のリリースを発表した。約2ヵ月の開発期間と7本のリリース候補（RC）版を経た通常通りの開発スケジュールで、リリース時は9月17日開催の「Linux Kernel Maintainer Summit」（オーストリア・ウィーン）の直前だったが、とくに大きな問題が発生することもなく、静かなローンチとなったようだ。 Linux 6.11 -Linus Torvalds Linux 6.11は最新版のAMDプラットフォームに向けた改善が多く実施されており、なかでも注目されるのが「Zen 3」に実装されている仮想マシン（VM）のセキュリティ機構「SEV-SNP（Secure Encrypted Virtualization Secure Nested Paging）」をx86カーネルでサポートしたことだ。AMDは2016年からS
LLVM/Clang Can Work Fine As A GCC Replacement For Linux Distributions - Phoronix
LLVM/Clang Can Work Fine As A GCC Replacement For Linux Distributions Written by Michael Larabel in LLVM on 5 February 2024 at 06:57 AM EST. 43 Comments While the performance of LLVM/Clang is on-par with GCC these days on both x86_64 and AArch64 and the C/C++ support is very robust compared to many years ago, most Linux distributions continue using the GCC compiler and GNU toolchain by default.

SaaSのグローバル化は幻想か？ 生成AIが「ベンダーの逆風」となり得る理由：らんぶるの「ｺｯｶﾗSaaS」 SalesforceのM&A分析ばかりでも単調化しそうなので、少し俯瞰して今後のSaaS業界のグローバル化について考えてみる。 SaaSに限ったことではないが、売り上げを増やすには顧客数を増やすか、単価を上げるしかない。SaaSを含むソフトウェアに限って言えば、提供価値を定数とした時の単価は上がらないようになっている。これはソフトウェアが常に改善されるという前提に依存し、その前提はおおむね正しい。 従って単価を上げるためには、技術開発のコモディティ化よりも速く提供価値を向上させる必要があるが、生成AIの到来により技術開発のコモディティ化が加速することは一目瞭然である。もちろん技術的革新は続く。しかしSalesforce誕生から25年、SaaS製品顧客としてわれわれが一貫して経験して
A Fix For The Severe Linux Performance Regression Spotted By Torvalds - Phoronix
A Fix For The Severe Linux Performance Regression Spotted By Torvalds Written by Michael Larabel in Linux Kernel on 14 January 2024 at 03:47 PM EST. 57 Comments Prior to Linus Torvalds' Internet and electricity being knocked out by a snow storm and thus impacting the Linux 6.8 merge window, his weekend was already in rough shape due to encountering a performance regression with new Linux 6.8 code
research!rsc: Hash-Based Bisect Debugging in Compilers and Runtimes
Setting the Stage Does this sound familar? You make a change to a library to optimize its performance or clean up technical debt or fix a bug, only to get a bug report: some very large, incomprehensibly opaque test is now failing. Or you add a new compiler optimization with a similar result. Now you have a major debugging job in an unfamiliar code base. What if I told you that a magic wand exists

20 years later, real-time Linux makes it to the kernel - really The work done on real-time Linux has benefitted the open-source OS for years, but it was only this week that Linus Torvalds admitted its last piece into the mainline kernel. Exactly what took so long? sjvnVIENNA -- After 20 years, Real-Time Linux (PREEMPT_RT) is finally -- finally -- in the mainline kernel. Linus Torvalds blessed the
