Google uses AI to estimate people's body fat based on smartphone photos they take. This method is said to estimate body fat more accurately than wearables. This PhotoScan AI is also said to be able to 'detect' insulin resistance, often a precursor to diabetes.

With the current significant investments and attention to consumer humanoid robotics this sounds like a very big deal. The difficulty of making dexterous hands could greatly benefit from powerful, compact 'actuators'.

> I read somewhere that the subconscious brain continues "working on problems" even when you are not actively working on it consciously. Hence the expression to "sleep on it".

It's something I've actively used for almost two decades now when dealing with challenges i'm stuck on. I remember one of my professors explaining it as having a 'prepared mind'.

What I do is, before I go to bed, try to summarize the problem to myself as concise as possible (like rubber ducking) and then go to sleep. Very often the next morning I wake up with a new insight or new approach that solves the problem in 10 minutes that took me hours the day before.

Three-dimensional printing offers promise for patient-specific implants and therapies but is often limited by the need for invasive surgical procedures. To address this, we developed an imaging-guided deep tissue in vivo sound printing (DISP) platform. By incorporating cross-linking agent–loaded low-temperature–sensitive liposomes into bioinks, DISP enables precise, rapid, on-demand cross-linking of diverse functional biomaterials using focused ultrasound. Gas vesicle–based ultrasound imaging provides real-time monitoring and allows for customized pattern creation in live animals. We validated DISP by successfully printing near diseased areas in the mouse bladder and deep within rabbit leg muscles in vivo, demonstrating its potential for localized drug delivery and tissue replacement. DISP’s ability to print conductive, drug-loaded, cell-laden, and bioadhesive biomaterials demonstrates its versatility for diverse biomedical applications.

What you're trying to solve is a form of social validation and trust that brick and mortar stores implicitly have: 1. They have to have spent a reasonable amount of money to actually be there; 2. A busy store with lots of people at the registers means there's enough trust to spend money here.

To solve this in a virtual environment you'd need a comparable amount of implicit trust. For #1 it's doable: have a trustworthy domain name. Amazon.com is a lot more trustworthy than look-at-my-shop.tk. For #2 I don't think there's a trustworthy equivalent, since it's either off-site by a third party or unverifiable by users.

I agree. As a programmer I never believe this is actual interaction of people but instead random events programmed to show up to spoof activity. There's no way to verify the truthfulness of the data. As a consequence I distrust the website and make an effort to find a different seller.

> More should be revealed on 18 March, when Nayak is due to give a talk on Microsoft’s topological qubit data at the American Physical Society meeting in Anaheim, California.

The field of quantum computing is very interesting for the difficulties and claimed immense gains when successful. The route that Microsoft has chosen for its research is a lofty one; doing it fundamentally different than others in the field. However, this 'break through' sounded exactly like the break through reported in 2018[1] which has been redacted.

I'm looking forward to the presentation 18 March

As a freelance back-end developer with various co-founding experience this question speaks to me. I think it's all a matter of perspective.

Looking at it from a development perspective the two can mean the same thing: we pivot and so we need to add new features.

However, in my experience the key is to look at pivoting from a non-development perspective. As mentioned in parent comments you pivot to find a product market fit. That entails finding your audience and the problem you're solving for them. Those questions do not require a product, but a human understanding. Questions like 'is it actually a problem they need solving, or a slight convenience?' and 'how are they solving their problem without my product?'.

By pivoting quickly in that space you don't get bogged down by technical issues or challenges that don't even matter, and the real solution might be a week's worth of time.

Reading the following part confused me, since that's how I learned and I don't know Mr. McIntyre:

> But my Scrum friends reminded me that stand-ups were never supposed to be status reports. They said that an evil elf named Yesterday-today-no-blockers McIntyre spread that lie around the industry long ago, and people have been confused ever since.

So I did some digging in the resources from the ScrumAlliance. There I found:

> The three-questions format was included in older versions of the Scrum Guide but no longer appears in the updated guide.

So what to do instead? I also found this snippet which I think is useful:

> The daily scrum is not a status meeting or status report. The purpose isn’t for a scrum master, manager, or stakeholder to see who is on schedule and who is behind; instead, it’s an opportunity for self-managing team members to synchronize with one another.

And to think Waymo is one of the most advanced self-driving cars at the moment and this is on a very controlled part of the city. It doesn't bode well for confidence in the self-driving car industry.
