can i say something controversial. the way people (especially american liberals but that's a whole nother can of worms) act about animal testing is sooooooooooo unhelpful. like is cosmetic testing on dogs/rodents/primates harmful and unnecessary? yes, in many cases! but does that mean all animal testing - for any application - should be categorically banned? no. animal testing is a vital process in many, many medical and research contexts and is conducted under a very strict set of standards, ergo applying "animal abuse" as a blanket label to all instances of animal testing is reductive at best and shows a flagrant lack of understanding of medical ethics on the part of the population. and don't even get me started on how slippery of a slope it is to go from condemnation of animal testing to just flat out eugenics

Loving Travis

For most of my open-source software projects, I use the Actions platform built into GitHub for CI (continuous integration). GitHub Actions provides virtual machines to run workflows, so I don't have to administer build environments for Linux, MacOS, Windows, and so on. It's modern, convenient (if you use GitHub instead of, say, GitLab), fairly reliable, and (best of all) free (for public repos).

For me, the main limitation of Actions is that all their hosted runners use the x64 architecture. Sometimes I want to build and/or test on Arm CPUs---for instance my Libbulletjme project, which has a bunch of platform-sensitive C++ code.

For Libbulletjme, I still depend on the older TravisCI platform, run by a private firm in Berlin. In addition to a huge selection of build environments based on AMD CPUs, Travis also provides Arm-based Linux environments. (Officially, they're a "beta-stage" feature, but they've been in beta for years.) Like Actions, Travis is also free to open-source projects, though their notion of "open-source" seems a bit stricter than GitHub's.

I mention Travis because my experiments with the Vulkan API exposed a limitation in Libbulletjme, which led me to begin work on a new release of Libbulletjme, which led me to discover an issue with Travis's Arm-based build environments. A recent change to these environments caused all my Arm-based builds to fail. I could only go a bit further with Vulkan before I would have to make hard choices about how to work around the limitations of Libbulletjme v18.5.0 .

At 20:09 hours UTC yesterday (a Sunday), I e-mailed TravisCI customer support and explained my issue. At 12:25 hours UTC today, Travis announced a hotfix to solve my issue. That's pretty good turnaround, for a non-paying customer having issues with a "beta-stage" feature on a summer weekend.

Bottom line: I still love Travis. <3

AI in DevSecOps: Revolutionizing Security Testing and Code Analysis

DevSecOps, short for Development, Security, and Operations, is an approach that integrates security practices within the DevOps workflow. You can think of it as an extra step necessary for integrating security. Before, software development focused on speed and efficiency, often delaying security to the final stages.  

However, the rise in cyber threats has made it essential to integrate security into every phase of the software lifecycle. This evolution gave rise to DevSecOps, ensuring that security is not an afterthought but a shared responsibility across teams. 

From DevOps to DevSecOps: The Main Goal 

The shift from DevOps to DevSecOps emphasizes applying security into continuous integration and delivery (CI/CD) pipelines. The main goal of DevSecOps is to build secure applications by automating security checks. This approach helps in fostering a culture where developers, operations teams, and security experts collaborate seamlessly.  

How is AI Reshaping the Security Testing & Code Analysis Industry? 

Artificial intelligence and generative AI are transforming the landscape of security testing and code analysis by enhancing precision, speed, and scalability. Before AI took over, manual code reviews and testing were time-consuming and prone to errors. AI-driven solutions, however, automate these processes, enabling real-time vulnerability detection and smarter decision-making. 

Let’s look at how AI does that in detail:  

AI models analyze code repositories to identify known and unknown vulnerabilities with higher accuracy. 

Machine learning algorithms predict potential attack vectors and their impact on applications. 

AI tools simulate attacks to assess application resilience, saving time and effort compared to manual testing. 

AI ensures code adheres to security and performance standards by analyzing patterns and dependencies. 

As you can imagine, there have been several benefits of this:  

Reducing False Positives: AI algorithms improve accuracy in identifying real threats. 

Accelerating Scans: Traditional methods could take hours, but AI-powered tools perform security scans in minutes. 

Self-Learning Capabilities: AI systems evolve based on new data, adapting to emerging threats. 

Now that we know about the benefits AI has, let’s look at some challenges AI could pose in security testing & code analysis: 

AI systems require large datasets for training, which can expose sensitive information if not properly secured. This could cause disastrous data leaks.  

AI models trained on incomplete or biased data may lead to blind spots and errors. 

While AI automates many processes, over-reliance can result in missed threats that require human intuition to detect. 

Cybercriminals are leveraging AI to create advanced malware that can bypass traditional security measures, posing a new level of risk. 

Now that we know the current scenario, let’s look at how AI in DevSecOps will look like in the future:  

The Future of AI in DevSecOps 

AI’s role in DevSecOps will expand with emerging trends as:  

Advanced algorithms will proactively search for threats across networks, to prevent attacks. 

Future systems will use AI to detect vulnerabilities and automatically patch them without human intervention. 

AI will monitor user and system behavior to identify anomalies, enhancing the detection of unusual activities. 

Integrated AI platforms will facilitate seamless communication between development, operations, and security teams for faster decision-making. 

AI is revolutionizing DevSecOps by making security testing and code analysis smarter, faster, and more effective. While challenges like data leaks and algorithm bias exist, its potential is much more than the risks it poses.

Continuous Integration (CI)/Continuous Deployment (CD) Software Testing Strategies

[kaijutegu]

Aug ABSOLUTELY deserves the praise, @ryukikit. St. Augustine Alligator Farm is one of my favorite animal facilities, hands down. It's a pretty zoo, doable in an afternoon if you kinda like crocodilians, or an all day affair if you REALLY like crocodilians. Here are my favorite things about it and why I think it's worth supporting.

1. They keep animals in interesting social groups.

Crocodilians are heavily involved parents, but most places that breed them don't have the enclosure space to let the babies stay with the parents. St. Augustine does. One of my favorite groups was their crèche of slender-snouted crocodiles. They had the parents and then a yearling cohort and a new hatchling cohort. This aligns with how these guys live in the wild- the babies stick around longer! They have the space for it, and they are very in tune with the social needs of their animals.

Very, very few zoos can keep their baby crocs with the adults and still perform maintenance and animal health checks safely. This doesn't mean these facilities are bad- it just means that they have different management practices. And frankly, a lot of these species aren't frequently bred elsewhere. Your average zoo doesn't need a setup where you can have a multiyear crèche for slender-snouted crocodiles. Some species have better success when the young are pulled early, and some zoos are better set up to raise out any offspring separately or behind the scenes. Every facility's practices are different, and this just happens to work well at St. Augustine and be really enjoyable to see as a zoo patron.

Crocodilians are exceptional parents and very protective. It's a sign of incredible animal management practices and animals that feel very comfortable with staff that St. Augustine can do this with nearly every species they breed.

2. They understand the social needs of their animals.

Some crocodilians are social. Some are solitary. Some can live happily with a member of the opposite sex but get territorial around members of the same sex. St. Augustine pays incredible attention to their social groupings to ensure that they aren't just meeting the animals' physical health needs but their social needs as well. They do continuous scientific research about social structures in crocodilians, taking blood samples to test stress hormones and observing stress behaviors to see how group dynamics change.

For example, St. Augustine is home to one of the world's largest known living saltwater crocodiles, Maximo. And his comparatively tiny mate, Sydney. During the educational presentations with these two, they point out that even their monster of a croc needs his social group- he won't eat if she's not around and he is calmer during medical checks if he can see her. These animal share a deep and special pair bond, and they make sure to talk about how the social aspect of these animals' lives is integral to their care. It's a unique aspect of the way they talk about these animals, because he IS a spectacle and he IS a sensation, but they don't talk about him like he's a mindless killing machine- they talk about him like he's a big, complex predator with social needs like any other animal. Aug is the only facility I've been to where the emotional and social needs of crocodilians is part of the education they provide guests- and speaking of education...

3. Their demos and presentations are extremely good.

The presentations at St. Augustine are some of the best I've ever seen, and I've seen literally hundreds of animal talks on everything from aardvarks to zebras. But as you... can probably tell from my blog content, I've spent a lot of time learning about and working with reptiles. I really enjoyed all of their presentations because they are very scientific about things and avoid sensationalism. They really want you to be fascinated by these creatures and love them- but more than anything else, they want you to respect them.

Also, they do a really good job handling their ambassadors. I really enjoyed something as simple as watching an educator tell us about snakes. Throughout the whole presentation she made sure that most of the snake's body was looped in her hand. The snake was always supported and was very calm. She gave the snake plenty of head room so that it didn't feel constricted- it was just good handling all around.

But also, the presentations made it clear how much the park cares about the animals' well-being. When they do the feeding and training presentations, they make it very clear that the animals' participation is entirely voluntary. They do things differently for their 9-foot saltie and their 16-foot saltie, because the 16-footer is so large and heavy he actually struggles walking on land sometimes. They adapt their programs and his care to ensure that he's completely comfortable- and he didn't actually participate in the whole feeding when I was watching! At no point did they try to push him into anything uncomfortable; they offered, he didn't engage, and they moved on. It was a clear expression of his boundaries, and I really appreciated how much his caretakers respected that.

4. Ethical Interactions

I've been to... a lot of tourist locations in Florida that have animals you can hold. Almost always against my will! Many of them are pretty terrible, and you don't actually learn much, if anything. But I really found that to not be the case at St. Augustine. Every single animal presentation and interaction opportunity was accompanied by education about the animal's biology, habits, and- crucially- their conservation status.

When I held a baby alligator at St. Augustine, the proctors- there were two, one to ensure I was holding the gator correctly and the other to educate- were very informative about the role alligators play in their ecosystem and their conservation history. The animals were all properly banded, and one of the two proctors was there to ensure that none of the baby alligators were uncomfortable. As soon as they started getting squirmy or tense, they were removed, unbanded, and taken to an off-exhibit area to relax. And when the babies age out of petting size, they just go in the lagoon to live with others of their species. I saw one upset alligator the entire time I was there, and he was clearly upset that his escape attempt was foiled by a keeper during my nursery tour.

Even though he's restrained in this shot, you can see that his full body and tail are supported, and the grip, while firm, is gentle. He's distressed, but after I took this picture, she put him in his enclosure and he calmed down immediately.

Sometimes when you have petting attractions with baby animals, those animals... don't have a happy ending. (See: cub petting.) But St. Augustine's program is fine- the gators are all aged out of wanting to have mom around, there's no declawing/defanging, and they're handled with care. And it's worth it, because people love what they understand. St. Augustine was integral in raising public awareness about alligators back in the 60s when they were endangered, and now they're thriving- largely in part to programs like St. Augustine getting people to care.

And speaking of getting people to care, let's talk about their research.

5. Shared Research Results

St. Augustine is also home to more species of crocodilian than anywhere else in North America- all of them, usually. (They didn't have a Tomistoma when I visited- that may have changed.)

Because of this species diversity, it's an incredible research resource. Having every species means that you can do a lot of work comparing their behaviors, their growth patterns, and more. They've been a major research site for crocodilian biology since the 1970s. Today, they're one of the key sites for studying crocodilian play and social behaviors. They actually maintain a blog where they post copies of papers that were written using their animals, meaning that you can actually see the results of the research your admission helps fund. You can see that right here: https://www.alligatorfarm.com/conservation-research/research-blog/

All of this adds up to a zoo that provides a unique experience, tons of actual education, and transparency about what its research and conservation steps actually are. St. Augustine's come a long way since its opening in 1893, and they really do want you to leave with a new respect for the animals they care for. Ultimately, if you're a fan of reptiles, you can feel good about visiting the St. Augustine Alligator Farm- their care and keeping are top of the line, they do a ton of innovative conservation research and support for conservation organizations, and you can see this animal there:

Post frustration

Last month I wrote about my frustration with a bug in one of my open-source software projects. The bug manifested in many different ways and only on continuous integration (CI) servers, not in my development environment. I felt stuck. Here's an update...

Eventually I managed to reproduce the bug locally. After many experiments, I narrowed it down to a pair of functions for cleaning objects when they're no longer needed. If object R got cleaned before object S, some test software would complete successfully. If S got cleaned before R, the test would crash. Code inspection showed that S's cleaner frees an object that R's cleaner needs to use. In other words, I had a "use-after-free" bug.

It wasn't obvious how to control the cleanup order, and I needed expert help to figure it out. Suffice to say, I fixed the bug.

However, the investigation made me aware of some similar bugs in the project, which I'm currently busy fixing.

December-January seems to be a difficult time of year for me. I experienced a slump a year ago during those months, and I seem to having another. I'm dealing with the current slump in various ways, both cognitive and biological. For instance, it's important for me to recognize that even when I'm at my worst, feeling down and tired and blue, I still manage to make progress on my software.

Things take longer, but I'm still making progress. And that spells "hope".

By Anthony Robledo

The side effects of newly discovered COVID-19 strain XEC might not be as severe, but is part of the more contagious variant class, experts say.

The Centers for Disease Control and Prevention (CDC) defines XEC as recombinant or hybrid of the strains KS.1.1 and KP.3.3., both from the Omicron family that became the predominant strain in the U.S. late December 2022.

The variant, which first appeared in Berlin in late June, has increasingly seen hundreds of cases in Germany, France, Denmark and Netherlands, according to a report by Australia-based data integration specialist Mike Honey.

XEC has also been reported in at least 25 U.S. states though there could be more as genetic testing is not done on every positive test, RTI International epidemiologist Joëlla W. Adams said.

"We often use what happens in Europe as a good indication of what might happen here," Adams told USA TODAY Friday. "Whenever we're entering into a season where we have multiple viruses occurring at the same time, like we're entering into flu season, that obviously complicates things."

What is the XEC variant? New COVID strain XEC is a recombinant strain of two variants in the Omicron family: KS.1.1 and KP.3.3.

The hybrid strain was first reported in Berlin late June but has spread across Europe, North America and Asia with the countries Germany, France, the Netherlands and Denmark leading cases.

Is the XEC variant more contagious? While there's no indication the XEC strain will increase the severity of virus, it could potentially become a dominant strain as Omicron variants are more contagious. However, current available COVID-19 vaccines and booster shots are particularly protective against XEC as it is a hybrid of two Omicron strains.

"These strains do have the advantage in the fact that they are more transmissible compared to other families, and so the vaccines that are currently being offered were not based off of the XEC variant, but they are related," Adams said.

Like other respiratory infections, COVID-19 and its recent Omicron variants will increasingly spread during the fall and winter seasons as students return to classes, kids spend more time inside and people visit family for the holidays, according to Adams.

How can we protect ourselves from XEC and other variants? The CDC continues to monitor the emergence of variants in the population, according to spokesperson Rosa Norman.

"At this time, we anticipate that COVID-19 treatments and vaccines will continue to work against all circulating variants," Norman said in a statement to USA TODAY. "CDC will continue to monitor the effectiveness of treatment and vaccines against circulating variants."

The CDC recommends that everyone ages 6 months and older, with some exceptions, receive an updated 2024-2025 COVID-19 vaccine to protect against the virus, regardless whether or not you have previously been vaccinated or infected.

Norman urged Americans to monitor the agency's COVID Data Tracker for updates to new variants.

KP.3.1.1:This dominant COVID-19 variant accounts for over 50% of cases, new CDC data shows

What is the dominant strain of COVID in the US? COVID-19 variant KP.3.1.1 is currently the dominant strain accounting for more than half of positive infections in the U.S. according to recent CDC projections.

Between Sept. 1 and Sept. 14, 52.7% of positive infections were of the KP.3.1.1 strain, followed by KP.2.3 at 12.2%, according to the agency's Nowcast data tracker, which displays COVID-19 estimates and projections for two-week periods.

KP.3.1.1 first became the dominant strain in the two-week period, starting on July 21st and ending on August 3rd.

"The KP.3.1.1 variant is very similar to other circulating variants in the United States. All current lineages are descendants of JN.1, which emerged in late 2023," Norman previously told USA TODAY.

COVID XEC symptoms There is no indication that the XEC variant comes with its own unique symptoms.

The CDC continues to outline the basic COVID-19 symptoms, which can appear between two to 14 days after exposure to the virus and can range from mild to severe.

These are some of the symptoms of COVID-19:

Fever or chills Cough Shortness of breath or difficulty breathing Fatigue Muscle or body aches Headache Loss of taste or smell Sore throat Congestion or runny nose Nausea or vomiting Diarrhea

The CDC said you should seek medical attention if you have the following symptoms:

Trouble breathing Persistent pain or pressure in the chest New confusion Inability to wake or stay awake Pale, gray or blue-colored skin, lips, or nail beds

2. In sub-Saharan Africa, ‘forgotten’ foods could boost climate resilience, nutrition

“[A study published in PNAS] examined “forgotten” crops that may help make sub-Saharan food systems more resilient, and more nutritious, as climate change makes it harder to grow [current staple crops.] [… The study identified 138 indigenous] food crops that were “relatively underresearched, underutilized, or underpromoted in an African context,” but which have the nutrient content and growing stability to support healthy diets and local economies in the region. […] In Eswatini, van Zonneveld and the World Vegetable Center are working with schools to introduce hardy, underutilized vegetables to their gardens, which have typically only grown beans and maize.”

8. The World’s Rarest Crow Will Soon Fly Free on Maui

“[… In] the latest attempt to establish a wild crow population, biologists will investigate if this species can thrive on Maui, an island where it may have never lived before. Translocations outside of a species’ known historical range are rare in conservation work, but for a bird on the brink of extinction, it’s a necessary experiment: Scientists believe the crows will be safer from predators in a new locale—a main reason that past reintroduction attempts failed. […] As the release date approaches, the crows have already undergone extensive preparation for life in the wild. […] “We try to give them the respect that you would give if you were caring for someone’s elder.””

““Battery minerals have a tremendous benefit over oil, and that’s that you can reuse them.” [… T]he report’s authors found there’s evidence to suggest that [improvements in technology] and recycling have already helped limit demand for battery minerals in spite of this rapid growth — and that further improvements can reduce it even more. [… They] envision a scenario in which new mining for battery materials can basically stop by 2050, as battery recycling meets demand. In this fully realized circular battery economy, the world must extract a total of 125 million tons of battery minerals — a sum that, while hefty, is actually 17 times smaller than the oil currently harvested every year to fuel road transport.”

Black Scientists and Engineers Past and Present Enable NASA Space Telescope

The Nancy Grace Roman Space Telescope is NASA’s next flagship astrophysics mission, set to launch by May 2027. We’re currently integrating parts of the spacecraft in the NASA Goddard Space Flight Center clean room.

Once Roman launches, it will allow astronomers to observe the universe like never before. In celebration of Black History Month, let’s get to know some Black scientists and engineers, past and present, whose contributions will allow Roman to make history.

Dr. Beth Brown

The late Dr. Beth Brown worked at NASA Goddard as an astrophysicist. in 1998, Dr. Brown became the first Black American woman to earn a Ph.D. in astronomy at the University of Michigan. While at Goddard, Dr. Brown used data from two NASA X-ray missions – ROSAT (the ROentgen SATellite) and the Chandra X-ray Observatory – to study elliptical galaxies that she believed contained supermassive black holes.  

With Roman’s wide field of view and fast survey speeds, astronomers will be able to expand the search for black holes that wander the galaxy without anything nearby to clue us into their presence.

Dr. Harvey Washington Banks 

In 1961, Dr. Harvey Washington Banks was the first Black American to graduate with a doctorate in astronomy. His research was on spectroscopy, the study of how light and matter interact, and his research helped advance our knowledge of the field. Roman will use spectroscopy to explore how dark energy is speeding up the universe's expansion.

NOTE - Sensitive technical details have been digitally obscured in this photograph. 

Sheri Thorn 

Aerospace engineer Sheri Thorn is ensuring Roman’s primary mirror will be protected from the Sun so we can capture the best images of deep space. Thorn works on the Deployable Aperture Cover, a large, soft shade known as a space blanket. It will be mounted to the top of the telescope in the stowed position and then deployed after launch. Thorn helped in the design phase and is now working on building the flight hardware before it goes to environmental testing and is integrated to the spacecraft.

Sanetra Bailey 

Roman will be orbiting a million miles away at the second Lagrange point, or L2. Staying updated on the telescope's status and health will be an integral part of keeping the mission running. Electronics engineer Sanetra Bailey is the person who is making sure that will happen. Bailey works on circuits that will act like the brains of the spacecraft, telling it how and where to move and relaying information about its status back down to Earth.  

 Learn more about Sanetra Bailey and her journey to NASA. 

Dr. Gregory Mosby 

Roman’s field of view will be at least 100 times larger than the Hubble Space Telescope's, even though the primary mirrors are the same size. What gives Roman the larger field of view are its 18 detectors. Dr. Gregory Mosby is one of the detector scientists on the Roman mission who helped select the flight detectors that will be our “eyes” to the universe.

Dr. Beth Brown, Dr. Harvey Washington Banks, Sheri Thorn, Sanetra Bailey, and Dr. Greg Mosby are just some of the many Black scientists and engineers in astrophysics who have and continue to pave the way for others in the field. The Roman Space Telescope team promises to continue to highlight those who came before us and those who are here now to truly appreciate the amazing science to come.
