Ukraine's defense ministry and two banks were knocked offline on Tuesday by a flood of malicious traffic designed to prevent people from visiting the sites, Ukraine's information security center said.
The distributed denial-of-service attacks targeted the websites for Ukraine's defense ministry, the Armed Forces of Ukraine, and two banks, Privatbank and Oschadbank, the country's State Service for Special Communication and Information Protection reported. At the time this post was being reported, the Defense Ministry site remained completely unreachable. Meanwhile, only the homepage for PrivatBank was available, and it was defaced. Oschadbank's site provided only limited access.
The malicious data floods were also reported by the Ukrainian cyberpolice, but at the time this post was being reported, attempts to visit most of the department's website were unsuccessful. The homepage said: "We apologize for the inconvenience. The site is under maintenance."
Incidental cases do not account for the jump in hospitalizations, the authors found.

Despite being widely seen as mild, the omicron coronavirus variant has been brutal on children and adolescents—particularly babies and toddlers, who are still ineligible for vaccination.
According to a study published Tuesday by the Centers for Disease Control and Prevention, the peak rate of pediatric hospitalizations during the recent omicron surge was four times higher than the peak seen during delta's wave last fall. And the largest increase was seen in children ages 0 to 4, who had a peak hospitalization rate five times higher than that seen amid delta's wave.
The study authors, led by CDC emergency response team researcher Kristin Marks, were careful to note that incidental cases of COVID-19 in hospitalized children do not account for the jump in rates amid omicron. Marks and colleagues looked carefully at medical charts from hospitalized children during both the delta and omicron waves. They compared the proportions of children coming into hospitals who had COVID-19-related symptoms at admission and were marked as being admitted specifically for COVID-19. Between the two waves, they found no significant differences in those proportions.

Pine64 is a company which develops hardware aimed at open source software enthusiasts and then encourages independent developers to create the software that will run on it. So far that approach has generated results with a series of affordable laptops, smartphones, and a tablet.
The company’s most recent product is a $399 E Ink tablet called the PineNote. It recently went on sale for $399, but Pine64 cautions that it’s currently only appropriate for developers and early adopters because software is still very much a work in progress. But that work is progressing.

Pine64 community manager Lukasz Erecinski highlights some recent progress in the company’s latest monthly update blog post. At this point all of the tablet’s hardware works with open source Linux software including the E Ink display, capacitive touch panel, Wacom digitizer, WiFi, Bluetooth, and audio.
Meanwhile, developers of several GNU/Linux distributions and user interfaces have begun porting their software to run on this E Ink tablet with a grayscale display, a slow screen refresh rate, and a Rockchip RK3566 processor. Some things aren’t working yet – including hardware-accelerated graphics, which means the user interface is sluggish. But things have come a long way since Pine64 began shipping the first units to developers a few months ago.
Here’s a roundup of recent tech news from around the web.
Software development for the upcoming PineNote E Ink tablet continues. Most hardware is now supported in Linux, a grayscale Plasma Mobile theme is in the works, and there’s initial support for postmarketOS with the Phosh and SXMO user interfaces.
Sony’s LinkBuds true wireless earbuds are the opposite of noise-cancelling: they’re designed to be wearable all day, allowing you to hear people and sounds around you without removing them. You can also control them by tapping nearby without touching.
Samsung’s Exynos 2200 processor with AMD RDNA 2 graphics appears to offer only a modest GPU performance boost over the previous-gen chip… and the same phone with a Snapdragon 8 Gen 1 chip trounces them both according to a recent review. The video review (which you can watch below) is in Turkish, which is why I’m linking to TechPowerUp’s summary.
Intel is acquiring Tower Semicondicutor for $5.4 billion to help shore up its foundry services (Intel manufactures chips for other companies). Tower specializes in things like RF, power, industrial sensors, and silicon-germanium. The move follows Intel’s recent $1 billion investment in third-party chip development including major contributions to organizations working on RISC-V architecture, also seen as an effort to shore up demand for Intel’s foundry services.
NVIDIA begins rolling out software version 9.0.1 for the Shield TV, bringing fixes for Plex media servers and other apps that use external storage which had been broken by the update to Android 11.

Roboticists can learn a lot about avoiding obstacles while pursuing a target from the flies.

Robber flies are aerodynamic acrobats, able to spot their prey, dodge around obstacles, and capture smaller insects at high speeds in midflights. Scientists have taken a closer look at how robber flies manage this amazing feat despite having brains on par with a single grain of sand. According to a new paper published in the Journal of Experimental Biology, the flies combine two distinct feedback-based navigation strategies: one that involves intercepting the prey when the view is clear, and another that allows the flies to swerve around any obstacles in their flight path.
One of the challenges in robotics is how to design robots that can navigate cluttered environments—something humans and other animals manage to do instinctively every day. Per the authors, many robotic systems rely upon a kind of path-planning: using sound (sonar) or lasers to send out signals and then detecting the reflections. That data can then be used to build a distance map of the surroundings.
But compared to using simple visual cues (i.e., "reactive methods"), path-planning is a costly approach in terms of energy use. Humans and other animals don't require elaborate maps or specific knowledge about a target's location, speed, and other details. We simply react to any relevant stimuli in our environment in real time. Devising navigational behavioral algorithms based on biological systems is thus of great interest to roboticists.

We’d seen galaxies with little dark matter, but had no explanation for them.

The first evidence for dark matter were galaxies that behaved as if they had far more matter than could be accounted for by the mass of their stars. Since then, we've found many other indications that the Universe is swimming with matter that we can only infer from its gravitational effect. And the original evidence that dark matter structures galaxies continued to hold.
Until that awkward moment in 2018 when we appeared to discover the existence of a galaxy with almost no dark matter. While there was skepticism regarding this initial finding, researchers eventually spotted a second galaxy that was very similar. Which was a problem, given that we had no idea how galaxies like this could form.
Now, researchers have announced that, while they were running a model of galaxy formation, a number of dark-matter-poor galaxies naturally popped out. And, by tracing the model back to see how those galaxies arose, the researchers are able to offer an explanation for these enigmas.
Hands-on: loading times, what “ray tracing” means on console, PC changes.

A surprise Tuesday presentation from game studio CD Projekt Red confirmed that its historicallybuggy 2020 game Cyberpunk 2077 is finally getting a "current-gen" patch for PlayStation 5 and Xbox Series X/S consoles. Then the studio immediately launched the patch.
In a move that reeks of either confidence or desperation, CD Projekt Red celebrated the milestone by offering a free, five-hour trial of CP77 on current-gen consoles. Interested players can now download the game in its entirety for free, though upon boot, a timer will appear at the screen's bottom-left to indicate how much time remains before the game is locked by a full purchase price. Since this trial doesn't lock down any of CP77's regions or content beyond a timer, players could conceivably speedrun the game; slower players, meanwhile, should know that this timer runs even while the game is paused or in menus. So lean on "sleep mode" or other ways to stop the timer, slowpokes!
Based on my tests of the patch on both PS5 and Xbox Series X, I would say CDPR is being more confident than desperate, though CP77 is by no means ironclad this many months after its December 2020 premiere.
