Open source software, whose source code can be modified and reused

, is difficult to establish a profitable business model because it is distributed free of charge . Even if you want to support open source financially, the support that can be done by individuals is limited, and in the case of organizations, it is possible that there will be an opinion that ‘you should not spend money on free distribution’. , This is also a difficult road. Entrepreneur Simon Willison cites ‘requesting a talk’ as an easy way to support such open source and explains why.

Willison points out that while companies often want to financially support accessible open source software, it can be more difficult than they think it would be. That’s because open source software doesn’t have a clear revenue structure and may not even accept donations. Even if the donation is accepted, if only a small amount of support such as ‘Can I get $ 5 (about 570 yen) for coffee?’ Is accepted, even if it is supported, it will not be fruitful for the project. Hmm.

Developers have been getting ready for months

Chrome, Firefox, and Edge are about to hit version 100, in a triple release that could break some websites. The move to version 100 in the coming weeks could result in bugs or compatibility issues on some websites not ready to read triple-digit user-agent strings. Google, Mozilla, and Microsoft are busy trying preempt any big issues.

Mozilla, Google, and Microsoft have been warning about the upcoming version 100 release for months, which is about to drop in March for both Chrome and Edge, followed by Firefox in May. Mozilla and Google have both been running experiments to test websites and report breakages. There’s a running list of issues, which is fairly small right now, and Engadget notes that the notable sites affected include HBO Go, Bethesda, and Yahoo.

“When browsers first reached version 10 a little over 12 years ago, many issues were discovered with User-Agent parsing libraries as the major version number went from one digit to two,” explains a team of web developers in a Mozilla blog. Much like the infamous Y2K bug that made the year 2000 indistinguishable from 1900 for some computers, browsers have different formats for user-agent strings, and “it’s possible that some parsing libraries may have hard-coded assumptions or bugs that don’t take into account three-digit major version numbers.”

Bing’s improved results drew in a developer, but a rich UI and Microsoft Rewards helped fully convert him to the search engine.

Luke Blevins is a developer interested in .NET, Azure, and Windows. He’s also a contributor to the popular third-party file explorer Files. Over the last two years or so, the developer switched to Bing as his primary search engine. Blevins’ recent Twitter thread discussing how the search engine has evolved over the years provides a unique perspective on Bing.

Blevins dipped his toe in the Bing waters before this recent experiment, but he never stuck around for long. That changed after Microsoft made significant improvements to Bing’s results, design, and feature set. Mostly drawn in by improved searched results, the dev came to appreciate other elements of Bing, such as its rich UI.

光学ストレージの一種である「ホログラフィックデータストレージ」（HDS）。過去に失敗に終わった取り組みもあるが、この技術が死んだわけではない。HDSがこれから革新を起こす可能性を深掘りする。

ホログラフィー（立体像を記録する技術）によってデータを記録する「ホログラフィックデータストレージ」（HDS）は、かつては光学ストレージの次世代候補に名を連ねていた。青紫色レーザーを使った光ディスクである「Blu-ray Disc」を上回る記録密度と、データへのアクセス速度が期待されていた。

さまざまな研究チームがHDSの開発に挑んできたが、プロトタイプはできてもそれ以上の芳しい成果につながることはなかった。ただし、その努力は無駄ではない。Microsoftの研究プロジェクト「Project HSD: Holographic Storage Device for the Cloud」は、クラウドサービスでの実用化を目指し、HDSに新たな息吹を注ぎ込んでいる。この研究開発は、Microsoftの研究部隊であるMicrosoft Researchとクラウドサービス「Microsoft Azure」のチームの共同研究だ。
