Your daily dose of tech news, in brief.
I just wanted to start today's edition of the Snap! with a big THANK YOU. Why? So many reasons, but the one we're going with today is SysAdmin Day!
While I doubt many are getting the day off (and I know some of you would work anyways, even if you could), I hope it is a relaxing and quiet day.You need to hear this. Akamai blocked largest DDoS in Europe against one of its customers
DDoS (distributed denial-of-service) attacks happen more often than we like, but, as you might imagine, the largest DDoS attack that Europe has ever seen is a bit rare.
According to BleepingComputer:
"The target, a customer of cybersecurity and cloud service company Akamai, has been under constant assault, facing dozens of DDoS rounds over the past 30 days.
DDoS incidents have become more frequent since the start of the year as attackers try to deny access to the victim's digital services by flooding them with requests and traffic to overwhelm resources and render them unavailable.
In a report this week, Akamai notes that the record-breaking attack occurred on July 21 and in 14 hours it peaked at 853.7 Gbps (gigabits per second) and 659.6 Mpps (million packets per second)."
Microsoft has released four new Windows previews, including Windows 10 22H2 preview for enterprise testing.
According to ZDNet:
"Microsoft has released four operating-system updates in one day – a new Windows 11 preview to the Insiders Dev Channel, two Windows 11 builds to the Beta Channel, and a Windows 11 22H2 build for the Release Preview Channel.
The Windows 11 releases arrived alongside the Windows 10 22H2 release rolling out to the Release Preview Channel. It's the next feature update to Windows 10 and is separate to Windows 11 22H2. Microsoft has been quiet about Windows 10 22H2, a minor release, and didn't announce any new features in the new build, but has since clarified it was released to validate its servicing technology."
SysAdmins: The Unsung Heroes of the Modern-day Workplace
Just in time for SysAdmin Day, Sarah Lahav, CEO of SysAid, explores the evolving role of system administrators and how that will fuel future growth in the IT sector.
According to Spiceworks News & Insights:
"IT workers are the ones who make things run smoothly and allow companies to go about their business. Alongside their high-value work, sysadmins also spend an inordinate amount of time on manual, repetitive tasks that other employees rarely see, like resetting passwords and onboarding, new employees. Without IT to keep the ship afloat, no business would succeed. From hospitals and factories to banks and universities, IT workers allow us all to enjoy the magic of technology and reap its benefits. Those IT workers deserve our praise and recognition, so we find a day like today to express our appreciation. "
We've all heard the joke about "Is your refrigerator running?" and we've heard about runaway brides and grooms, but have you heard about a runaway star (and no, I don't mean the movie star kind)?
According to Space.com:
"Zeta Ophiuchi is on the go.
The star, which is 20 times more massive than our sun and located some 440 light-years from Earth, is zipping through the galaxy at about 100,000 mph (162,000 kph). That's rather unusual for stars, which typically circle the center of their galaxy in a rather calm, organized manner. A new study has uncovered evidence supporting the leading theory as to why Zeta Ophiuchi has gone rogue, wandering across the Milky Way.
Scientists suspect that Zeta Ophiuchi once belonged to a binary system, but that its companion star was destroyed in a supernova more than a million years ago. The shockwave from the explosion propelled Zeta Ophiuchi into space, sending it on its high-speed journey. Now, for the first time, astronomers have developed 3D computer models of the shockwave in an attempt to explain the bubble of X-ray emissions detected around the star."
Earth's crust is dripping 'like honey' into its interior under the Andes
While we normally look to the stars in this section, we're looking a little closer to home this time.
According to Space.com:
"Earth's crust is dripping "like honey" into our planet's hot interior beneath the Andes mountains, scientists have discovered.
By setting up a simple experiment in a sandbox and comparing the results to actual geological data, researchers have found compelling evidence that Earth's crust has been "avalanched away" across hundreds of miles in the Andes after being swallowed up by the viscous mantle.
The process, called lithospheric dripping, has been happening for millions of years and in multiple locations around the world — including Turkey's central Anatolian Plateau and the western United States' Great Basin — but scientists have only learned about it in recent years. The researchers published their findings about the Andean drip June 28 in the journal Nature: Communications Earth & Environment."
AMD has teased the imminent launch of their Ryzen 7000 Series processors.
According to Engadget:
"The list didn't include technical details. In its Computex demo, however, AMD showed a 16-core CPU that reached a 5.5GHz clock speed. That might represent the Ryzen 9 7950X. All of the 7000 series will be based on a new Zen 4 architecture that delivers twice the Level 2 cache per core, maximum boost speeds above 5GHz, AI acceleration and support for technologies like DDR5 memory and PCIe 5.0. You'll need an AM5-compatible motherboard to make the leap, but AMD is promising a 15 percent or higher increase in single-threaded performance."
Scientists use dead spider as gripper for robot arm, label it a 'Necrobot'
And one for the weekend. I mean, seriously, how could I not spotlight a story that has initiated the field of "necrobotics"?
According to The Register:
"Scientists from Rice University in Texas have used a dead spider as an actuator at the end of a robot arm – a feat they claim has initiated the field of "necrobotics".
"Humans have relied on biotic materials – non-living materials derived from living organisms – since their early ancestors wore animal hides as clothing and used bones for tools," the authors state in an article titled Necrobotics: Biotic Materials as Ready-to-Use Actuators.
The article, published by Advanced Science, also notes that evolution has perfected many designs that could be useful in robots, and that spiders have proven especially interesting. Spiders' legs "do not have antagonistic muscle pairs; instead, they have only flexor muscles that contract their legs inwards, and hemolymph (i.e., blood) pressure generated in the prosoma (the part of the body connected to the legs) extends their legs outwards.""
And bring it back around from the beginning, Happy SysAdmin Day!
