The specialists have discovered one more crack at the International Space Station and suspect that yet another one exists, ISS Russian Segment head Vladimir Solovyov told Rossiya-24.
"So far, we have found one place and suspect another, where as some kind of leak exists. We must bring a powerful microscope on a cargo spacecraft and use to examine this place. We are not totally certain so far," Solovyov said.
He underscored that air loss due to the crack are insignificant.
"This leak is like as if you’d drill the hull with a 0.2 mm diameter drill. I’m not sure such drills even exist in household. As for the leak it causes, our [space air] pressure is 750 mmHg, and this alleged crack causes us to lose 0.3 to 0.4 mmHg every day," the official said, adding that emergency leak starts when pressure falls at 0.5 to 1 mmHg per minute.

Scientists from the International Centre for Radio Astronomy Research (ICRAR) and the University of Western Australia (UWA) have set a world record for the most stable transmission of a laser signal through the atmosphere.
In a study published today in the journal Nature Communications, Australian researchers teamed up with researchers from the French National Centre for Space Studies (CNES) and the French metrology lab Systèmes de Référence Temps-Espace (SYRTE) at Paris Observatory.
The team set the world record for the most stable laser transmission by combining the Aussies' phase stabilization technology with advanced self-guiding optical terminals. Together, these technologies allowed laser signals to be sent from one point to another without interference from the atmosphere. ...[S]enior researcher Dr. Sascha Schediwy said the research has exciting applications. "If you have one of these optical terminals on the ground and another on a satellite in space, then you can start to explore fundamental physics," he said. "Everything from testing Einstein's theory of general relativity more precisely than ever before, to discovering if fundamental physical constants change over time."
The technology's precise measurements also have practical uses in earth science and geophysics. "For instance, this technology could improve satellite-based studies of how the water table changes over time, or to look for ore deposits underground," Dr. Schediwy said.
There are further potential benefits for optical communications, an emerging field that uses light to carry information. Optical communications can securely transmit data between satellites and Earth with much higher data rates than current radio communications.

Brown University researchers have shown a way to make bulk metals by smashing tiny metal nanoparticles together, which allows for customized grain structures and improved mechanical and other properties.
Metallurgists have all kinds of ways to make a chunk of metal harder. They can bend it, twist it, run it between two rollers or pound it with a hammer. These methods work by breaking up the metal’s grain structure — the microscopic crystalline domains that form a bulk piece of metal. Smaller grains make for harder metals.
Now, a group of Brown University researchers has found a way to customize metallic grain structures from the bottom up. In a paper published in the journal Chem, the researchers show a method for smashing individual metal nanoclusters together to form solid macro-scale hunks of solid metal. Mechanical testing of the metals manufactured using the technique showed that they were up to four times harder than naturally occurring metal structures.
“Hammering and other hardening methods are all top-down ways of altering grain structure, and it’s very hard to control the grain size you end up with,” said Ou Chen, an assistant professor of chemistry at Brown and corresponding author of the new research. “What we’ve done is create nanoparticle building blocks that fuse together when you squeeze them. This way we can have uniform grain sizes that can be precisely tuned for enhanced properties.”

A website is offering to sell gigabytes of files allegedly obtained as a result of the recently disclosed SolarWinds breach.
Called "SolarLeaks", the website offers source code allegedly obtained from Microsoft, Cisco, SolarWinds and FireEye. The information allegedly taken from Microsoft, offered for $600,000, is contained in a 2.6 Gb file and the seller claims it includes partial source code for Windows and “various Microsoft repositories.”
The cybercriminals behind the SolarLeaks website claim they are willing to sell all files for $1 million, and they also claim they still have access to the systems of targeted companies and this is only the first batch of data. They also claim they can provide proof that their offer is legitimate.
While some members of the cybersecurity industry believe SolarLeaks is likely a scam, others believe the seller could really possess the files they are offering, with some saying it could be a misdirection attempt.

Mozilla is working on a design refresh for the organization's Firefox web browser that it refers to as Photon internally. The last major design refresh of Firefox was unveiled in Firefox 57 in November 2017; it was known as Proton back then.
Mozilla did change several interface elements after the release of Firefox 57, recently the controversial address bar overhaul that it launched in Firefox 75 Stable.
Information about the design refresh is limited at this point in time. Mozilla created a meta bug on Bugzilla as a reference to keep track of the changes. While there are not any mockups or screenshots posted on the site, the names of the bugs provide information on the elements that will get a refresh. These are:
The Firefox address bar and tabs bar.
The main Firefox menu.
Infobars.
Doorhangers.
Context Menus.
Modals.

First was it origami with which Japan delighted space engineers and provided inspiration in the construction of satellites. Now Japan is aiming to use wood in space to reduce the impact of satellites on our atmosphere, which could mean the wood-working classes at school are going to pay off for space engineers, too.
As funny as it sounds at first, is it a much needed step. With tens of thousands of planned Low-Earth-Orbit satellites all destined to burn up in our atmosphere in the next decade is it important to preserve our environment as early as possible and not just after the pollution becomes visible.

Other worlds aren’t the only difficult terrain personnel will have to traverse in humanity’s exploration of the solar system. There are some parts of our own planet that are inhospitable and hard to travel over. Inner Mongolia, a northern province of China, would certainly classify as one of those areas, especially in winter. But that’s exactly the terrain team members from the China Aerospace Science and Technology Corporation (CASTC) had to traverse on December 16th to retrieve lunar samples from the Chang’e-5 mission. What was even more unique is that they did it with the help of exoskeletons.
Strangely enough, the workers wearing the exoskeletons weren’t there to help with a difficult mountain ascent, or even pick up the payload of the lunar lander itself (which only weighed 2 kg). It was to set up a communications tent to connect the field team back to the main CASTC headquarters in Beijing.The exoskeletons were designed to help people carry approximately twice as much as they would be able to. Local state media described a single person carrying 50kg over 100m of the rough terrain without becoming tired. Setting up communications equipment isn’t all the exoskeletons are good for though. They were most recently used by Chinese military logistics and medical staff in the Himalayas, where the country has been facing down the Indian military over a disputed line of control.

For many years malware was solely a threat to Windows users — but that era is over. Cyber criminals have come to view Linux as a viable target for their attacks due to the growing popularity of the open-source OS and the plethora of high-value devices it powers.
2019 and 2020 have been plagued by the emergence of dangerous Linux malware variants — CloudSnooper, EvilGnome and HiddenWasp, among many others — and this trend is expected to be magnified in 2021 and beyond, as Linux malware operators are recognizing great success with their malicious campaigns. Thus, taking proactive measures to secure your Linux systems against malware has never been more important.
Reverse engineering, or the process of deconstructing malware in an artificial environment such as a Linux system to gain insight into its design, architecture and code, is a highly effective method of malware detection and analysis. This article will examine how reverse engineering can be used to secure Linux systems against malware and other exploits, and will introduce our favorite tools, toolkits and utilities for reverse engineering and malware scanning available to Linux users.

Plenty is an ag-tech startup in San Francisco, co-founded by Nate Storey, that is reinventing farms and farming. Storey, who is also the company’s chief science officer, says the future of farms is vertical and indoors because that way, the food can grow anywhere in the world, year-round; and the future of farms employ robots and AI to continually improve the quality of growth for fruits, vegetables, and herbs. Plenty does all these things and uses 95% less water and 99% less land because of it.
Plenty’s climate-controlled indoor farm has rows of plants growing vertically, hung from the ceiling. There are sun-mimicking LED lights shining on them, robots that move them around, and artificial intelligence (AI) managing all the variables of water, temperature, and light, and continually learning and optimizing how to grow bigger, faster, better crops. These futuristic features ensure every plant grows perfectly year-round. The conditions are so good that the farm produces 400 times more food per acre than an outdoor flat farm.
Another perk of vertical farming is locally produced food. The fruits and vegetables aren’t grown 1,000 miles away or more from a city; instead, at a warehouse nearby. Meaning, many transportation miles are eliminated, which is useful for reducing millions of tons of yearly CO2 emissions and prices for consumers. Imported fruits and vegetables are more expensive, so society’s most impoverished are at an extreme nutritional disadvantage. Vertical farms could solve this problem.

Howls of anguish from betrayed CentOS users highlight the value of its long support cycles. As distros become more refined how important are changes vs. stability for users running tens, thousands and hundreds of thousands of servers or who just want stability and security over change for its own sake? Should competitors like Ubuntu and SUSE offer truly LTS versions to seize that (obviously large thus important to widespread adoption) user base? Distro-hopping is fun but people with work to do and a fixed task set have different needs.
Why do you think distro leadership are so eager for distro life cycles? Boredom, progress or what mix of both?
What sayeth the hive mind and what distros do you use to achieve your goals?

Nashville authorities believe an explosion that occurred in downtown Nashville early Christmas morning was an "intentional act" sparked by a vehicle blast.
Police came across a suspicious RV parked outside a nearby AT&T building near Second Avenue and Commerce Street before 6 a.m., when initially responding to calls of shots fired in the area, said Metro police spokesperson Don Aaron.
There was no immediate evidence of any shooting but officers alerted the department's bomb squad, which was en route when a "significant explosion" happened about 30 minutes later, Aaron said.
Just before the blast, witnesses in the area reported a dire warning coming from the RV: “Evacuate now. There is a bomb. A bomb is in this vehicle and will explode."
Then, the voice started a 15-minute countdown.
Officers were conducting door-to-door checks in the area and redirected a man walking his dog along the street. The force of the explosion knocked an officer to the ground and gave another officer what police hope is temporary hearing loss. Three people were hospitalized with injuries, police said.
AT&T service in Nashville and Middle Tennessee was affected for many customers Friday, said company spokesperson Jim Greer, citing damage to facilities from the explosion. The outage affected 911 access in several jurisdictions across the region throughout the day.

Today, Christmas morning at 6AM an RV filled with explosives detonated in front of a tall, windowless AT&T / NSA Building on 166 2nd Avenue North in downtown Nashville, Tennessee. Why? What was in that building? Did it host centralized monitoring equipment? Was the goal to disrupt communications in order to commit another crime (for example disabling alarm monitoring)? Was the goal to shutdown a service co-located to that building?
Or did the AT&T building have nothing to do with this plot and the location was random? This explosion apparently wasn't meant to cause mass casualties or inflict terror.
Things that make you go hmmmmm..... on Christmas.
Merry Christmas to all!
