You only have one body and it is not going to stay the same. Time takes a toll on all of us and there is no such thing as a perfect body. It is important to have a positive body image, because that’s what you’re stuck with. Now scientists from the University of Waterloo found that relationships also affect the way we feel about our bodies.

The problem of body image is especially big in women. Men seem to be more relaxed when it comes to the way they look. They also are not under so much societal pressure when it comes to their image. Scientists wanted to see what shapes body image in women and therefore they asked a group of young women to indicate the way they perceive their bodies. Participants of the study also had to describe the way their body image changes depending on the social circle they are in – how they view themselves when they are with family members, friends, coworkers and such.

Unsurprisingly, scientists found that the body image does depend on the social context. For example, when a young woman is surrounded by people who are preoccupied with their appearance she is more likely to be self-conscious about her body. There is also an issue of size – big contrasts in the body size do make women think about their bodies more negatively in some cases. Scientists say that this is a big issue, especially among young women, who are often into fashion, looks and social media. Previous researches have shown that a positive body image improves mental health outcomes and contributes to a better quality of life.

Those young women that surrounded themselves with people who were more accepting of their body, less body preoccupied, and more similar in size to them, were feeling better. It is very important, because a negative body image is a huge risk factor for eating disorders, which are absolutely lethal. In fact, eating disorders have the highest mortality rate of any mental health condition.

Allison Kelly, senior author of the study, said: “We are trying to help people give thought to the different people they are interacting with and how other people may affect the way they feel towards themselves. The findings also suggest that our qualities and behaviours could have an impact on the body image of the people around us.”

It is always good to wish to improve yourself, but that wish has to be based in health. Fitness is great, but, again, it has to be pursued in a healthy way. And even if you need to lose a few kilograms, you have to be able to love yourself through that process. If you think you’re suffering from a bad body image, surround yourself with positive people that make you feel accepted. And consider therapy – it is always a good idea.

Wild West for developers when it comes to writing cloud-native apps

Commentary: Containers ate your infrastructure, but what comes next at the application layer? A new survey points to big, industry-wide decisions to be made about the tech used to write applications.

Twenty years ago it seemed certain that the underpinnings of future data center infrastructure would be Linux clusters running on x86 “commodity” hardware. We just didn’t know what to call it or where exactly it would run.

The big systems vendors like IBM, Sun, HP, and Cisco weren’t calling it “cloud”; instead, the vendors named it utility computing, autonomic computing, grid computing, on-demand, and n- other terms. At Comdex 2003, it was reported on ZDNet that “participants in a panel discussion at Comdex agree that utility computing is more like a river than a rock, but have little luck nailing down a real definition.” (ZDNet is a sister site of TechRepublic.)

Two decades later we know what to call it (“cloud”), and we know it’s built with containers and a whole lot of Linux. As detailed in the new Lightbend survey Cloud Native Adoption Trends 2020-2021, 75.2% of respondents already host the majority of their applications in some sort of cloud infrastructure, and roughly 60% run most of their new applications in Kubernetes/containers.

Now we’re faced with another major rethink that will affect tens of millions of developers operating at the application layer, where there are common threads on crucial concepts, but everyone is bringing different and predictions for the future.

Higher up the stack

We’ve all felt this happening as containers have eaten into the virtual machine landscape, as web programming languages (JavaScript) surpass JVM/server-side languages (Java) in developer popularity, and as serverless, JAMstack, and other still-being-named phenomena change the “developer experience” in writing cloud-native applications. The diversity of choice in the “right way” to write software for the cloud has become a bit of a Wild West for developers.

As Google developer advocate Kelsey Hightower put it earlier this year, “There’s a ton of effort attempting to ‘modernize’ applications at the infrastructure layer, but without equal investment at the application layer, think frameworks and application servers, we’re only solving half the problem.”

“There’s a huge gap between the infrastructure and building a full application,” said Jonas Bonér, CTO and co-founder at Lightbend, in an interview. “It’s an exercise for the programmer to fill in this huge gap of what it actually means to provide SLAs to the business, all the things that are hard in distributed systems but needed for the application layer to make the most of Kubernetes and its system of tools.”

Lightbend’s cloud adoption report highlights some of these major decision points that remain murky for the application layer of the cloud-native stack.

“Building cloud-native applications means creating software that is designed with the advantages—and disadvantages—of the cloud in mind,” said Klint Finley, author of the Lightbend survey. “It means taking advantage of the fact that it’s possible to outsource entire categories of functionality—like databases and authentication—to public cloud services and planning for the fact that communication between those cloud components might be unreliable.”

Some developers still prefer frameworks they personally maintain and scale, while the business side clearly prefers frameworks that are delivered “as a service” via API, the survey says. Namely, 54.7% of managers said it was their highest priority to write business applications that specifically leverage the underlying cloud infrastructure vs. 38.3% of developers. Meanwhile, consuming back-end services by API rather than building and maintaining your own is the defining characteristic of the emergent JAMstack (JavaScript / API / Markup) architecture that has the weight of Facebooks’ React programming language momentum behind it. But it’s a completely different approach than the old-school server-side mindset for Java developers that still rule the roost and command vast legacy systems at most major enterprises.

The survey also suggests that developers think about cloud computing more in terms of specific technologies like Kubernetes and containers, while management thinks of cloud computing more as a new way to build applications. Management tends to prefer outsourcing as much maintenance as possible, while developers’ preference for configurability over automation reveals a desire not to lose too much control over the many layers of an application stack. As one respondent put it: “SaaS comes with ease of adoption and faster time to market, however many do not understand the cost of running them at scale.”

New materials help expand volumetric 3D printing

Researchers at Lawrence Livermore National Laboratory (LLNL) have adapted a new class of materials for their groundbreaking volumetric 3D printing method that produces objects nearly instantly, greatly expanding the range of material properties achievable with the technique.

New materials help expand volumetric 3D printing

Using a custom volumetric additive manufacturing 3D printer, Lawrence Livermore researchers were able to build tough and strong, as well as stretchable and flexible, objects nearly instantly from a class of materials known as thiol-ene resins. Photo by Maxim Shusteff/LLNL.

The class of materials adapted for volumetric 3D printing are called thiol-ene resins, and they can be used with LLNL’s volumetric additive manufacturing (VAM) techniques, including Computed Axial Lithography (CAL), which produces objects by projecting beams of 3D-patterned light into a vial of resin. The vial spins as the light cures the liquid resin into a solid at the desired points in the volume, and the uncured resin is drained, leaving the 3D object behind in a matter of seconds.

Previously, researchers worked with acrylate‐based resins that produced brittle and easily breakable objects using the CAL process. However, the new resin chemistry, created through the careful balancing of three different types of molecules, is more versatile and provides researchers with a flexible design space and wider range of mechanical performance. With thiol-ene resins, researchers were able to build tough and strong, as well as stretchable and flexible, objects, using a custom VAM printer at LLNL. The work was recently published in the journal Advanced Materials and highlighted in Nature.

“These results are a key step toward our vision of using the VAM paradigm to significantly expand the types of materials that can be used in light-driven 3D printing,” said LLNL engineer Maxim Shusteff, the work’s principal investigator and head of a Laboratory Directed Research & Development project in advanced photopolymer materials development.

In the paper, researchers also demonstrated the first example of a method for designing the 3D energy dose delivered into the resin to predict and measure it, successfully printing 3D structures in the thiol‐ene resin through tomographic volumetric additive manufacturing. The demonstration creates a common reference for controlled 3D fabrication and for comparing resin systems, researchers said.

The team concluded the work represents a “significant advancement” for volumetric additive manufacturing as they work toward their goal of producing high‐performance printed engineering polymers, with particular emphasis on using thiol‐ene materials in biological scaffolds. Thiol‐ene materials have shown promise for applications including adhesives, electronics and as biomaterials, researchers said.

“By implementing a nonlinear threshold response into a broad range of chemistries, we plan to print with resins such as silicones or other materials that impart functionality,” said LLNL materials engineer Caitlyn Cook.

By studying how the resin behaves at different light dosages, researchers added they aim to improve the agreement between computational models and experiments and apply photochemical behavior to the computed tomography reconstructions that produce the 3D models used to build objects.
