Researchers at Harvard Business School and University of Toronto used unique data to quantify the value of open source.

Takeways:

* Supply-side (cost to recreate) is ~$4.15B, but demand-side (value to firms) is $8.8T. Shows massive cost savings & productivity boost from OSS.

* If OSS didn't exist, firms would need to spend an estimated 3.5 times more on software than they currently do. OSS provides a massive, often invisible, productivity boost.

* A tiny fraction of OSS developers create the vast majority of value. Only 5% of developers are responsible for over 96% of the demand-side value

* Firms should not just "free ride" on OSS but actively contribute to the ecosystem, as this is far cheaper than recreating the software themselves.

vivaldi notesというワードが流れてきて、なんぞこれ、と思ったら・・・ブラウザの機能なのね@@!すごいな、vivaldi。

help.vivaldi.com/ja/desktop-ja

私は、主にfedibirdを見るのに使ってるよーー。多機能だけど、それ以外に使っていないので、大変もったいない感じ😅

前は、Chromeとfirefoxを使っていた。今は、Chromeを外して、vivaldiに変更。いや、なんとなく・・・

Edge君が住み着いているはずだけど、ピン止め等々も外してしまっているので、姿を見ることは、めったにない・・・

(考えてみたら、結構いろいろブラウザ触った気がする。SeaMonkeyとかーー)

You have probably seen this on by user u/lukakopajtic. It was viral but not very accurate 😅 recommending and as "EU alternatives"? How? Anyway, he just updated the infographic, and it's much, much better! Most issues have been corrected. I think there is still a couple of issues I disagree with: 1) recommending instead of 2) recommending instead of (but OK, I can understand this if the focus is on self-sovereignty only), 3) recommending instead of (but, even here, I can understand if the goal is to replace ), and 4) recommending as a comparison to (nothing wrong with Thunderbird, but that's an email client, not a Gmail-like suite provider, I would have rather recommended or ). Kudos for the initiative though, the intentions are good!

デスクトップ版 Vivaldi 7.2:スピードとスマートさを追求した本気のアップデート


よりスマートでスピーディーに機能するアドレスバー

デスクトップ版 7.2 では、ウェブへの入り口となるアドレスバーを重点的に改良しました。その結果、より素早いアクセスと、より関連性の高い結果の表示が実現しました。提案機能を最適化することで、検索の正確性が向上し、必要なものをスムーズに探せるようにしました。

ブラウジング速度にこだわる方なら、今回のリリースでスピードや効率性がアップしたのも実感できるはずです。欲しい情報をサクサク入手できます。

Vivaldi はユーザーが主役のブラウザです。ユーザー自身がアドレスバーを自分の使い方に合わせてカスタムできる良さはこれまで通りです。

ちょっとした魔法により素早いページの読み込みが実現

Vivaldi 7.2 では接続のハンドリングを新たに最適化し、ページがより素早く読み込まれるようにしました。その違いを実際に体感してください。2 倍以上早くなったと感じる方もいるかもしれません。実は特別な仕掛けはなく、純粋に最適化を行った結果です。

キーボードショートカットを上書き

パワーユーザーが喜ぶ新機能です。Vivaldi には広範囲に及ぶキーボードショートカットが備わっています。その中で、「特定のショートカットはブラウザ側を優先する」といった指定が可能になりました。これにより、ブラウザ側でよく使うショートカットが、ウェブページ側で用意されているショートカットとかぶっても安心です。キーボードショートカット愛用者にとって、かゆいところに手が届く機能です。

メールからカレンダーの予定を直接作成

メールとスケジュールが連携して機能するようにしました。メールやウェブページから直接予定を作成できます。ミーティングのリクエストやコンサートチケットの確認などのメールから手動でコピペしなくても、右クリックで表示されるコンテキストメニューから、すぐに予定を作成できます。

Vivaldi メールのメッセージのコンテキストメニューで、「カレンダーに追加」オプションが強調されている様子。

その他の新機能:

  • 通貨ウィジェット新たに導入した通貨ウィジェットにより、ダッシュボードでリアルタイムの為替レートを表示できます。
  • ワークスペース用のクイックコマンドクイックコマンドを使ってワークスペースを素早く見つけられるようにしました。
  • メールアカウントの並べ替え複数のメールアカウントを管理している場合、Vivaldi メールでアカウントの並べ替えを行えるようにしました。

新しい Vivaldi を試す準備はできましたか?

Vivaldi 7.2 にアップデートして、是非、今回の新機能や改善点を体感してください。

Vivaldi コミュニティの一員であるみなさん、いつもありがとうございます。リリース毎に Vivaldi を向上していけるよう、共に挑戦していきましょう。

2023年の12月の記事、再掲。
この時から「13カ月」経っている。
なんて世界は無慈悲で無力なんだろうって泣きそうになる。

“正確に報じてほしい。逃げ場のない住民を兵糧攻めにした上で狙い撃つ、世界で最も卑怯(ひきょう)かつ残虐な軍隊の行為には、正当性のかけらもないのだから”

“目的はハマスを殲滅することなどと喧伝されているが、そうではない。「それは実現可能な目標ではなく単なるスローガンだ」とイスラエルの識者が指摘している。隠された真の目的は、ガザを破壊し尽くし、200万人以上の住民を住めなくして、追い払うことである”

”そのような中、飛び出したのがグラム米上院議員の「暴言」だ。CNNテレビのインタビューに対し、グラム氏は「東京やベルリンを壊滅させた時、何人死んだかなんて気にしたか?」と述べて、オースティン国防長官は「ナイーブすぎる」と批判したのである。この暴言の背後に横たわる闇は深い。「戦争はどんな汚い手を使おうと、勝てばよいのだ」という論理が、イスラエルのシオニスト政権を支配していることは想像に難くない“

ハマス殲滅は単なるスローガン、真の目的は…◇東海大学客員教授・アラビア語同時通訳者 新谷恵司【コメントライナー】

시민단체 등이 "거기에 사람이 많아서" 트위터를 그만둘 수 없다는 입장은 이해하지만 다른 채널을 준비하지 않고 중요 공지를 트위터에만 올리는 건 결국 단체 소식을 알고 싶어하는 사람들이 트위터 운영사가 조장하는 혐오와 악의에 노출되도록 돕는 결과를 낳는다고 생각해요.

IFTAS 2.0 – Rescoping and Refocusing

Since its inception, IFTAS has worked to support volunteer moderators, administrators, and community managers across decentralised social media platforms, equipping them with the tools and guidance needed to foster safe, inclusive spaces.​

While we haven’t been able to raise the funds needed to accomplish all our goals, we’ve been humbled to receive over $5,000 in additional support from our community since January, and this ensures there are plenty of activities we can continue to support.

The Story So Far

Over the past two years, IFTAS has achieved several significant milestones:​

  • Community Building – We established the IFTAS Connect community portal, bringing together over 200 moderators and administrators to share best practices, resources, and support.
  • Guidance and Resources – In collaboration with community moderators and industry experts, we developed comprehensive guidance materials, such as the DSA Guide for Decentralised Services and the Moderator Library to assist communities in navigating federated content and behaviour.
  • Moderation Tools – We launched services like FediCheck, a web service that allows service providers to review and subscribe to external sources for automated domain blocking. We also built and piloted a CSAM detection service that demonstrated a novel way to approach this issue for administrators seeking to reduce this harm.
  • Advocacy and Support – IFTAS has been a vocal advocate for decentralised communities, participating in broader trust and safety discussions and providing direct support to moderators facing challenges.

Given financial constraints, IFTAS is refocusing on its most impactful initiatives to ensure sustainable support.​

Services Scheduled for Shutdown

As part of our re-scoping, we are discontinuing services that are unsustainable or lack sufficient support. These include the Content Classification Service, FediCheck (now available for download), Tall Poppy Personal Digital Safety Services, Bluesky Labeller, and the Moderator Mastodon Sandbox. Most of our planned activities such as OSA Guidance and legal support are no longer being worked on. 

We sincerely thank all users, contributors, and supporters of these services. Your efforts have been invaluable in promoting trust and safety across the open social web.

Continuing Initiatives

Despite these changes, IFTAS remains committed to several core initiatives that align with our mission to build and sustain trust and safety at scale in the Fediverse.​

  • IFTAS Connect – We will continue to support the public library and moderator connection activities of IFTAS Connect. This community platform serves as a vital resource for moderators and administrators, offering access to a wealth of information, best practices, and a supportive community of peers.
  • Social Web Domain Observatory – The CARIAD project is what informed our FediCheck service, and it aggregates data on the most blocked domains within the Fediverse, providing valuable insights to help service providers manage federation and enhance the safety of their communities. CARIAD will be converted to a domain observatory. We will provide updates on the observatory’s availability as development progresses.

  • Moderator Handbook – Our community has authored a detailed handbook for moderators, and we are working to bring this to the community as soon as possible.
  • SW-ISAC – Our information sharing activities will remain, and we will issue alerts as and when appropriate, as well as keeping the IFTAS DNI list up to date. Follow https://mastodon.iftas.org/@sw_isac for the relevant alerts and notices.
  • Moderator Needs Assessment – We plan to continue our annual survey of moderators and admins.

By focusing on these core activities, IFTAS will continue its support for decentralised communities, ensuring that moderators and administrators have the resources they need to maintain safe and inclusive environments.​

Thank you to everyone who has advised, participated, convened, or in any way supported trust and safety on the social web – you are what makes all of this possible, and we are excited to continue finding ways to support the Fediverse and everything it stands for.

노잼숫자라는 것은 존재하지 않습니다 (자연수로 한정할 경우)

1은 기초니까 유잼이라고 합시다
2는 유일한 짝수인 소수이니 유잼이라고 합시다
3은... 1이 소수가 아니라고 하면 홀수인 첫번째 소수니까 유잼이라고 합시다
5는 곱하면 10이 막 만들어지므로 유잼이라고 합시다
그렇다면 4가 노잼이겠군요!
엥 근데 그렇다면 4는 '가장 작은 노잼 숫자'가 되어 매우 유잼이 되어버립니다
이렇게 반복하면 모든 자연수는 노잼이 아니게 됩니다
그러므로 노잼 숫자는 존재하지 않습니다

@bglbgl gwyng Donald Knuth의 이 격언이 생각나네요:

프로그래머들은 자신의 프로그램에서 중요하지 않은 부분의 속도에 대해 생각하거나 걱정하는 데 엄청난 시간을 낭비합니다. 이러한 효율성 추구는 디버깅과 유지보수를 고려할 때 오히려 큰 부정적 영향을 미칩니다. 우리는 작은 효율성에 대해, 즉 약 97%의 경우에는 잊어버려야 합니다. 조기 최적화는 모든 악의 근원입니다. 하지만 그 중요한 3%의 기회는 놓치지 말아야 합니다.​​​​​​​​​​​​​​​​

the "doxing ex" theory seems plausible to me.

another: troll theory: all of these spaces (fedi, friendica, discord, matrix) are nerdy, specifically the kind of nerd used to evade surveillance. her chat rooms are full of pleroma-type racists. the whole thing may be some sort of elaborate 4chan troll, who has impersonated either a really existing Nicole or some random girl they have video clips of. troll doesn't respond to DMs or contacts but is currently trying to gather more momentum before doing something cringe.

facts I know for sure:

- The same DM has been mass sent from probably over 100 different Fediverse instances, since around Jan 31 2025 to this day.
- The DM has some pointedly specific details about Nicole the Fediverse Chick (Polish girl from Toronto, studying pre-health).
- The putative university varies (Toronto Metropolitan University, George Brown College).
- The DM uses nerd lingo ("Fediverse Chick") and points to several nerdy/non-mainstream social media spaces attributted to "Nicole" (friendica, discord, matrix, stumblechat).
- "Nicole" accounts so far have never responded to contacts, or to my knowledge ever tried to scam or bait or even talk to followers in any way.
- The chat rooms (discord, matrix) are abandoned. The admin "Nicoles" never post anything.
- As of yesterday, my "Nicole" DMs are pointing to a Friendica at namestaci.cz. There are also Friendicas at friendica.world (3 times), my-place.social, friendica.io, poliverso.org.
- The Friendica accounts expose a putative work address in Toronto, publicly (!!).
- There's many different photos for "Nicole". All appear to be the same woman and not AI-generated. All are very low quality; someone suggested early 2000s webcam photos, but they look more like video stills to me. Many of the photos clearly group together into the same source video, same outfit etc.
- The namestaci.cz Friendica posted a photo two days ago, titled "My dad's office. He works in renovation and always has a lot going on." This, too, is low quality like a video still.
- The friendica.world accounts have a few dozen photos, most of them seemingly random stills from the videos. (edit: many look like, random or automated/sneak shots of the ceiling or from awkward angles etc.)
- At some point there were "Nicole" Peertube instances. I've watched one cached video, said to be about "hanging out around work"; it shows probably the woman from the photos, walking in the cold somewhere consistent with the Friendica work address. She was talking in the video, but the version I found had no audio.
- At some point there were "Nicole" "live" streams. Reports are that it was some video of the same woman, on loop.
- Reportedly, at some point her Matrix room had the topic "I work at the ****. Come say hi sometime! I work in the **** section, so just ask for Nicole!" This has since been removed.

the more I look at this, the more I think it's targeted harassment of an actual Nicole. either by someone she knows like a vengeful ex, or by 4chan-style trolls who got their hands on a few video clips and personal details.
