> Heart disease is the most common cause of death — not just in industrialized countries, but for the world as a whole. Many deaths caused by heart failure could be prevented if the patient received medical care sooner, but people are often unaware of impending heart failure until it actually occurs. However, there are physiological indicators that become detectable in advance of heart failure. This wearable “health belt” contains sensors that monitor for those indicators to give warning of imminent heart failure so patients can seek lifesaving medical attention.
> This health belt has a variety of sensors to monitor key physiological indicators, including thoracic impedance, heart rate, electrocardiogram activity, and motion activity. None of those alone would reliably correspond to upcoming heart failure without many false positives and negatives, but together they provide a clear picture. The sensor array, which is wearable and resembles a cumberbund, communicates via Bluetooth with the user’s phone. When the signs of heart failure appear, their phone can either notify them to seek medical attention or notify a third party, like a family member or doctor.

> The W3C recently elected a Board of Directors (BoD) for the new W3C Legal Entity. Several new board members are currently on the W3C Advisory Board (AB) and they decided to step down from the AB to focus on the BoD. The W3C is holding a special election for the remaining 6-18 months of the terms of those four AB seats. This blog post is an extended version of my personal nomination statement for that election.
> Hi, I’m Tantek Çelik and I’m running for the W3C Advisory Board (AB) to help it reboot W3C as a community-led, values-driven, and more effective organization. I have been participating in and contributing to W3C groups and specifications for over 24 years.
> I am Mozilla’s Advisory Committee (AC) representative and have previously served on the AB for several terms, starting in 2013. In the early years I helped lead the movement to offer open licensing of W3C standards, and make it more responsive to the needs of independent websites and open source implementers. In my most recent term I led the AB’s Priority Project for an updated W3C Vision. I set the example of a consensus-based work-mode of summarizing & providing granular proposed resolutions to issues, presenting these to the AB at the August 2022 Berlin meeting, and making edits to the W3C Vision according to consensus.

> This tutorial will help ypu installing software required to develop desktop Ubuntu applications with C++ language and GTKmm library version 4. You might want to do so following examples of the excellent programs created with GTKmm like Ardour, Inkscape, GParted, Rawtherapee and even VisualBoyAdvance. This is an alternative to programming with C/GTK as we published back in 2018. We will show you how to prepare the tools, write your first program, compile it and repeat it.

> One of the huge benefits of WebAuthn is that it makes traditional phishing attacks impossible. An attacker sends you a link to a site that looks legitimate but isn't, and you type in your credentials. With SMS or TOTP-based 2FA, you type in your second factor as well, and the attacker now has both your credentials and a legitimate (if time-limited) second factor token to log in with. WebAuthn prevents this by verifying that the site it's sending the secret to is the one that issued it in the first place - visit an attacker-controlled site and said attacker may get your username and password, but they won't be able to obtain a valid WebAuthn response.
> But what if there was a mechanism for an attacker to direct a user to a legitimate login page, resulting in a happy WebAuthn flow, and obtain valid credentials for that user anyway? This seems like the lead-in to someone saying "The Aristocrats", but unfortunately it's (a) real, (b) RFC-defined, and (c) implemented in a whole bunch of places that handle sensitive credentials. The villain of this piece is RFC 8628, and while it exists for good reasons it can be used in a whole bunch of ways that have unfortunate security consequences.
