Ubuntu 26.04 Ends 46 Years of Silent sudo Passwords

Ubuntu 26.04 Ends 46 Years of Silent sudo Passwords. Starting with the upcoming LTS release, every keystroke at a sudo password prompt will echo an asterisk — a small UX fix that has ignited one of Linux's fiercest debates in years.

⚠️ Update: Three full weeks have passed since 's internet blackout came into effect, with users forced onto the National Information Network.

At hour 504, few circumvention tools work as authorities crack down on satellite and VPN users outside the state-approved whitelist.

Graph from NetBlocks showing network connectivity in Iran from 24 February 2026 to 21 March 2026. The y-axis represents normalized connectivity, ranging from 0% to 100%, and the x-axis represents the dates. The green line representing Iran's connectivity is high through the initial time period, with a sharp drop on the morning of 28 February. The continued drop in connectivity aligns with a nation-scale internet blackout imposed by authorities after joint military strikes by the US and Israel. A brief restoration was observed on 18 March. The minimum and current connectivity levels are indicated as 1% and 2%, respectively. The chart has a dark background with a red horizontal arrow labeled 'SHUTDOWN' indicating the disruption period, and the NetBlocks logo in the lower left corner with the Mapping Internet Freedom slogan.

@hongminhee洪 民憙 (Hong Minhee) :nonbinary: Lots of interesting issues here. (Note that the schema.org JSON-LD namespace for PropertyValue is incorrect too.) I think brower.pub is arguably being too strict. One must be careful to think about AS2 like data types in a strongly-type programming language. Mastodon could document that PropertyValue is an "extension type" of Object. Implicitly, it is anyway. The type property for an Object is optional and so are all the rest of the properties. A {} is a valid Object.

Extending ActivityPub: A Recipe | Steve Bate

Occasionally there are online discussions about using schema.org vocabularies with ActivityPub (AP) and Activity Streams 2.0 (AS2). There are many ways to do this, but this article will explore one approach using a schema.org Recipe type. The information is focused on AP/AS2 messaging rather than user interface considerations related to displaying the recipe. Although the ... Read more

CloudNativePGでPostgreSQLクラスタを建てて、バックアップ・リストアまでやってみた - await wakeUp();

はじめに Kubernetes上でPostgreSQLを動かすために、CloudNativePGを使ってみました。 これまでは単純にPostgreSQLのコンテナをPodとして動かしていましたが、レプリケーションやバックアップ・リストア周りを手軽に使えそうなので、運用面を考えてCloudNativePGを選びました。 CloudNativePGでPostgreSQLクラスタを建てて、Barman Cloud Pluginを使ったS3互換ストレージへのWALアーカイブ、定期バックアップ、バックアップからのリストアまでを一通り試したので、設定や手順について記録しておこうと思います。

Reminder that people see different things depending on what the alternative is: blog.rust-lang.org/2026/03/20/ says that every cohort complains about Rust compile times. However, for me, Rust speeds up the compile&debug cycle compared to C++. It’s impractical to compile a piece of Gecko C++ separately from Firefox, so with C++, I have to compile Firefox as a whole and then upload a recording of executing Firefox as a whole to Pernosco. With Rust, I can typically iterate on a component separately.

How AI Agents See Your Website: The Accessibility Tree Explained · IsAgentReady

AI agents don't see your website the way humans do. They navigate via the accessibility tree — a browser-generated structure originally built for screen readers. We explain how it works, which AI frameworks use it, and why accessible websites outperform in the age of AI agents.

Heading home after the second day on Love the fact that this community is so very open to innovation and creating different spaces online that support other ways of interaction, self-organization and self-expression, where this room is getting smaller and smaller everywhere else. In that sense, it is a free haven for creative thinking and tinkering, an online breeding ground for the open web. Thanks everyone!

I’ve been working in the accessibility field for over 20 years. I’ve worked as an expert witness in numerous ADA cases, performed scores of accessibility audits, trained well over 1,000 developers around the world, and consulted for some of the biggest public and private sector organizations on earth.

Some documentation for the second .
We finished last night with a really nice Conference Dinner.
Today, we started with 3 session slots.

The first session I hosted and talked "Financial Sustainability". This is still a very open problem. A lot of the work is done in free time or funded with small grants. This needs future proofing, no matter in what direction the growth is.
My moonshot solution idea: Having more services like Ghost or ecommerce platforms on the Fediverse. How cool would it be if we could buy and discover stuff from a lot of different small artists or companies. Especially if we can standardize and I don't need to manually enter my data every time I'm buying something from a new shop. This could crossfinance, other areas?!

After that, there was some talks about EU funding, structures of the Fediverse for youth work, and so many other conversations.

This is also how the conference looks from the waterway. Still really good conversations and weather!

So, an interesting issue came up in the repo that I've been thinking about: #629.

You know how every server uses schema:PropertyValue in actor attachment for profile metadata fields (like “Website”, “GitHub”, etc.)? Turns out, strict validators like browser.pub reject it, because the AS2 spec says attachment should only contain Object or Link—and PropertyValue is a schema.org type, not an Activity Streams 2.0 type.

The thing is, we can't just drop the type like we did with Endpoints (#576), because Mastodon and others rely on seeing "type": "PropertyValue" to render profile fields. But at the same time, it's technically not spec-compliant.

I'm leaning towards writing a to formalize this existing practice rather than trying to invent a new type (like toot:PropertyValue extending Object), which would be a nightmare to migrate across the whole fediverse.

What do you all think? Has anyone else run into this? Would love to hear thoughts from implementers and spec folks.

Apple Quietly Blocks Updates for Popular 'Vibe Coding' Apps [Updated] macrumors.com/2026/03/18/apple

Apple Quietly Blocks Updates for Popular 'Vibe Coding' Apps [Updated]

Apple has quietly blocked AI "vibe coding" apps, such as Replit and Vibecode, from releasing App Store updates unless they make changes, The Information reports. "Vibe coding" tools allow users with little to no programming experience to build apps or websites using natural language prompts. Their accessibility has driven rapid adoption among both developers and non-technical users.
