Google looks to electronic waste as cost-effective AI server solution

Gizmag news -

Every year, billions of phones are discarded globally, many of them with perfectly usable processors. At the same time, the tech industry is preparing to spend billions on new AI computing hardware, at high environmental costs. Google, in collaboration with researchers at the University of California, San Diego, is developing a way to bridge those two realities by building a server from recovered phone processors, tackling a waste problem while providing low-carbon computing.

We retested the Panasonic L10, just to be sure

Digital Photography Review news -

When we wrote our review of the Panasonic L10, we tried to make sure we put the studio comparison into context. For mirrorless cameras and DSLRs we use good prime lenses, stopped-down to the point that their performance is reliably excellent: zoom lenses and, in particular, the downsized, retractable zoom lenses in compact cameras, can't match up to this standard. As a result, compacts don't look quite as impressive.

Our test scene lets you compare images in incredibly fine detail, revealing differences that you wouldn't see in most real-world situations: they exist but that doesn't mean they matter. That's exactly why we also post a gallery of real-world sample images so that you can relate the things you see in the studio scene to their photographic impact.

We'd gone through our usual processes for compact cameras: carefully align, shoot a series of images, compare to cameras we'd expect to perform similarly, then do it again at a different focal length, to make sure we were representing the camera fairly.

However, we still saw some concerns expressed that we were testing a "faulty" or sub-standard copy. Just to be certain, we requested another L10, to see whether we'd get a significantly different result.

Test and retest Image ComparisonThis widget is not optimized for RSS feed readers. Click here to open it in a new browser window / tab.

It didn't. With the first copy, we found that the 75mm setting looked better than the 50mm we'd used on the LX100 cameras. The difference was much smaller on the second copy. Both copies could be a touch sharper at the center at 75mm whereas 50mm equiv was less sharp at the center, more consistent out to the corners, which is presumably why we chose it for the LX100s.

Multiple focus attempts, using both manual focus and autofocus, appear to suggest that a lot of the softness in the corners is a result of curvature of field: a non-flat focus field, meaning it's not possible to get the whole of the chart in focus at the same time. The images with the sharpest center focus had worse looking corners than the images with slightly miss-focused center.

Ultimately we were able to shoot some images that are sharper at the center than the ones displayed in our image comparison tool, but they have visibly less sharp corners. The second copy of the camera also appears less consistent, with what appears to be slight decentering sometimes affecting the top left corner.

The images between the two cameras are similar enough (decentering aside) that we don't think we can get consistently better images from the second copy than the ones already in the scene. Those images already exhibit aliasing – a sign that the lens is resolving detail beyond the level the sensor's resolution can accurately capture – suggesting the lens is doing a good job. You just need to consider the context of how finely you're scrutinizing them and how impossibly the high the standards set by good, prime lenses are.

We re-tested the L10 because we want to make sure our image comparison tool shows all the cameras in it in as fair a light as possible. And if that means re-doing some of the work and re-checking our assumptions to ensure our standards are maintained, then it's worth doing.

Flame plasma pyrolysis process turns spent coffee grounds into biofuel

Gizmag news -

Humans drink approximately 400 billion cups of coffee annually, leaving behind 18 million tonnes of wet coffee grounds, roughly the weight of the three Great Pyramids of Giza. These grounds, which mostly end up in landfill, have the potential to be fuel. However, their moisture poses a significant challenge. Scientists at the Korea Institute of Geoscience and Mineral Resources (KIGAM) have devised a technique to turn still-wet coffee grounds into high-grade biofuel in as little as 90 seconds.

A ton of great content and related photography is created by the DPReview community in our forums: lively discussions, sharing of gear and photography in spotlight articles, collaborative photo events and more. In this "What you missed" roundup for June, we highlight community forum activity from the past month, including some of the photography that didn't make it into articles.

Scroll down to the section of interest as previewed in this list:

  • Article of the month: Joining a local photography group
  • 'What's in your bag?' community member spotlights
  • Question of the week
  • Join our collaborative photo chain

Article of the month: Joining a local photography group

"A group shot (excluding me) of that first meetup that I attended."

DPReview's Features Editor, Abby Ferguson, wrote a great piece about the benefits of joining local photography groups. As a community manager, I naturally found this article fascinating and the kind of advice I feel all of you would find a great insight into photographers outside our forums. After reading her article, I even took it upon myself to look up some photography groups in my local corner of Texas, United States.

"Despite my reluctance, I knew meeting other photographers would only be a good thing. Plus, as this is a place my husband and I will be for the long term, I wanted to set down some roots and finally make some connections here. And so, last fall, I finally put aside my reservations and attended a meetup." - Abby

What's in your bag? A community member spotlight

Mark Lamb shared his portrait photography in celebration of our week of portrait-themed community content. Below is an interesting excerpt from Mark's story about his fondness for portrait photography in Britain. The photo above is a new one he provided us that we couldn't fit into the article.

"In recent years, my work has become centered on a long-term project called One Thousand Contemporary Portraits, an attempt to create a broad and inclusive portrait archive of contemporary Britain. The project has taken me from fishing communities and military veterans to Goths, performers, campaigners, artists and ordinary people whose stories might otherwise go unrecorded."

Question of the week: we ask, you tell

Every other week, we ask the community a question about their photography, usually on a specific topic, with the results spotlighted on DPReview's front page and in the forums the following week. There are often many great photos submitted that we don't get a chance to spotlight them all in a single article.

Here is a newly revealed reader's photo and excerpt of their story from the latest question.

What camera is your most memorable? Photo: thorstenwulff

Featured quote: "My first love was the F3. In the summer of 1987, she went to New York with me and a box of T-Max 400. Paired with a 24mm F2.8 lens, it was my perfect combo for street photography, even if you had to get a bit closer. The other lens was the 105mm F2.5. In early May this year, I took them back to Manhattan, but was put off a bit by the flood of gimbal-toting influencers everywhere Instagram deems worthy of a shot. This couple is one of my favorite pictures from 39 years ago. I love the tenderness between them." - thorstenwulff

Discussion of the month: Why is it so difficult to buy a first camera today? Photo: FrancoD

Community member, BernardoSC, asked a great question in the forums that has gained quite a bit of traction. He asked everyone, "Why is it so difficult to buy a first camera today?" This is an excellent question, BernardoSC! I have asked this question of myself recently about various purchase interests, from cameras to computer equipment.

Here is a peek at what others had to say:

JT26: It's hard as there are so many options now. New cameras and new versions of the above are using new tech and are not sold in millions like they used to be, so they are naturally more expensive.

ahaslett: The optical viewfinder is what limits your choice. Apart from retro designs, cameras these days are nearly all mirrorless. There isn’t much between a phone and a camera for £1,000, given how fast phones have improved.

Plankowner110: In the 1960s, you simply adjusted aperture, shutter speed, and focus ring, and it didn't matter if you were using an inexpensive Sears Tower (camera) or a rugged pro-body Nikon F. The major variable was selecting which film to use. Cameras all operated basically the same way, and one could easily pick up any brand of camera and begin shooting. We didn't have to peruse a myriad of menu settings or press tiny re-programmable buttons all over the camera body.
