![]() Surfshark used to consistently rate as one of the fastest VPNs available, but we've been disappointed with its inconsistent speeds recently. ![]() ![]() We didn't find any language in either document that would indicate Surfshark has any obligation to share user data with its parent company or any sibling companies, which include NordVPN. Since February 2022, Surfshark and NordVPN have had the same corporate parent, but Surfshark said it is legally bound not to share any information between the entities that would go against its privacy policy or terms of service. Surfshark passed its first independent no-logs audit in January. And although no-logging claims are virtually impossible to prove with 100% certainty, German cybersecurity firm Cure53 declared Surfshark's security to be "solid" in its 2021 security audit of the VPN. Surfshark says it doesn't log any user activity. With its Dynamic MultiHop, IP Randomizer and IP Rotator functions, the Nexus network can give you a few extra layers of protection while you use the VPN - which can be particularly beneficial to users with critical privacy needs. The functionality is somewhat similar to Tor, but Surfshark says it's faster. ![]() One innovation we're excited to see Surfshark roll out over the next year is its Nexus network, which connects the VPN's entire network of servers together and allows you to choose multiple servers to route your connection through. You'll also get access to Surfshark's CleanWeb technology, which blocks ads and malware and helps you avoid phishing attacks. That's what helped Surfshark earn CNET's Editors' Choice for Best Value VPN in 2022.Īlong with standard VPN features such as a kill switch and DNS leak protection, some of the more notable Surfshark features include camouflage mode (which hides the fact you're using a VPN), split-tunneling, NoBorders mode (which lets you use Surfshark in regions where VPNs are restricted) and multihop VPN connections. And it's still significantly cheaper than most of its competitors. Surfshark boasts an impressive suite of privacy and security features, unlimited simultaneous connections, easy-to-use interface and expansive global network of more than 3,200 servers in 100 countries. You can also opt for a $13 per-month plan, or pay $60 for six months. ExpressVPN's best plan offers five simultaneous connections for $100 a year (which includes three extra months, for a limited-time deal totaling 15 months of service). The company has been in business since 2009, and ExpressVPN has a substantial network of more than 3,000 RAM-only servers spread across 160 locations in 94 countries. So does its 24/7 customer support, and its no-questions-asked, 30-day money back guarantee. In the past year, ExpressVPN increased its independent third-party audit count, published details about its TrustedServer deployment process, joined the i2Coalition to call for improved VPN industry ethics, and released the open-source Lightway encryption protocol.Īll of our top-rated VPNs have wide compatibility across platforms and operating systems, but ExpressVPN's collection of setup guides, detailed FAQs and troubleshooting articles give it a clear advantage for users. ExpressVPN has included an on-board IP address checker, along with two leak testers and a password generator. A single button on its landing screen directs you to connect quickly, with the only accompanying option a drop-down server location selector with your fastest nearby city selected by default.ĮxpressVPN's other options - its security and privacy tools, account and settings options, and support page - are all kept neatly tucked away under a garden-variety three-bar icon in the screen's top left corner. Its apps for iOS and Android are designed with a streamlined approach aimed at connecting fast without fuss. ExpressVPN is one of the fastest VPNs we've tested, registering an 18% speed loss in our latest tests in February and March of 2023. ![]() Unzip the program and run it to cleanly remove any and all remnants of Armoury Crate from your PC. Head to the Armoury Crate support page, click the Show More link at the bottom, and click the Download button next to the Armoury Crate Uninstall Tool. Improper uninstallation and reinstallation can cause issues with certain features, so for best results and a clean system, you’ll need to use our dedicated Armoury Crate Uninstall Tool. However, with multiple separate services governing these different pieces of hardware, we don’t recommend that you uninstall Armoury Crate using Windows’ built-in Add and Remove Programs menu, and we definitely don’t recommend the use of any “Registry Cleaners” or similar programs. That’s less for you to download, and less unnecessary bloat on your PC. If you have an ROG mouse and keyboard, for example, but not an ROG headset, it’ll only download the modules for those two pieces of hardware. Step One: Run the Armoury Crate UninstallerĪrmoury Crate uses a modular system, where it only downloads the components it needs for the hardware you have. Here’s how get Armoury Crate back up and running with a clean slate. ![]() ![]() If you previously had Armoury Crate installed on your system, or you’re looking to do a clean reinstall to start from scratch, you need to take the proper steps. If you have ROG hardware in your PC-whether it’s one of our motherboards or an entire laptop-our Armoury Crate software manages many of the exclusive ROG features available to your rig. ![]() Not only was this weekend’s closure useless security theater - touted routinely during news broadcasts, because “something must be done” - but it misdiagnoses the problem. This is why Minneapolis needs the Stone Arch Bridge open all the time. It’s the only place in the city that consistently passes the street musician test: If there aren’t buskers on the Stone Arch Bridge at sunset, the streets of Minneapolis should be deemed lifeless. I saw everyone from new immigrants to Minneapolis lifers, street musicians, convention-goers, joggers, downtown lanyard types, and more. Last Thursday, the evening before MPRB closed the bridge, the bridge boasted the diversity of the Twin Cities. No matter how many times you’ve done it, crossing the Stone Arch Bridge remains unique. Nothing else even comes close downtown it’s the one part of the city where all walks of life cross paths, from CEOs to conventioneers to the unsheltered. It’s important because public spaces, where people from all over the region come together, attract vitality creating a virtuous cycle. The Stone Arch Bridge is the best public space in Minneapolis, the urban icon that literally appears on nearly every tourism video, public relations campaign, and in generations of prom photos. This is why it boggles the mind that Minneapolis and its Park and Recreation Board (MPRB, the elected entity managing Minneapolis park space) closed the car-free Stone Arch Bridge during the evenings of a key holiday weekend. ![]() Now more than ever, downtowns need to foster vitality, a critical mass of “eyes on the street,” and other urbanist clichés. The correct reaction from city leaders has been to place more emphasis on street life. Minneapolis is not alone, as post-COVID work patterns have swept through Midwestern downtowns like a tsunami of emptiness. Everyone seems to agree that downtown Minneapolis, whether on the brink or the cusp, is poised at a pivotal moment where something needs to happen. ![]() And to get the party going in larger spaces, Outdoor Boost cranks up the bass even further. Wirelessly connect EPICBOOM, BOOM, BOOM 2, BOOM 3, MEGABOOM, MEGABOOM 3 and HYPERBOOM speakers for the ultimate sound experience. The fan-favorite feature on the BOOM app, PartyUp, lets you pair multiple Ultimate Ears speakers together so you can kick your parties up a notch. These modes optimize sound for solo and group activities including yoga, meditation, parties, beach days, and more. You can also customize the mids, highs, and lows of the sound based on your personal preferences. ![]() Through the BOOM app, which is updated as of today, you can choose between different pre-set EQs including Signature, Bass Boost, Game/Cinema, Podcast/Vocal, and the all-new Deep Relaxation mode. Additional EPICBOOM features include an LED battery indicator and a USB-C connector. The sensor establishes a Bluetooth shortcut that allows users to simply power on, pair, connect, and play, also making it easy to switch between multiple people’s playlists within seconds. Instead of a fussy manual set-up, the speaker has a one-touch NFC feature available for NFC-compatible smartphones with Android 8.0 or later. The speaker allows for up to 17 hours of playtime and has a Bluetooth range of 55 meters. When you want to move a party from indoors to outdoors, EPICBOOM’s internal microphone dynamically adjusts EQ and balances the sound accordingly, so you never miss a beat.ĮPICBOOM is available in two sleek colorways: Cotton White + Lipstick Red and Charcoal Black + Lime. With an IP67 rating, EPICBOOM is waterproof, dustproof, and floatable, making it the perfect companion for epic moments at home and outdoors. This speaker will no doubt be a part of life’s epic moments.”ĭesigned for big sound, built for epic momentsĮPICBOOM’s oval design creates an impressive internal acoustic volume, and is coupled with a 4.6” woofer for bass clarity and immersive sound. We’re excited to add EPICBOOM to our product portfolio. ![]() This speaker boasts our signature Ultimate Ears high-fidelity sound while delivering plenty of volume. “Customers want huge sound in a conveniently portable package and that’s what we have delivered with EPICBOOM. “We design our products with our customers and their lifestyles in mind,” said Jonah Staw, general manager of Ultimate Ears. Made of 100% post-consumer recycled polyester fabric and a minimum of 59% post-consumer recycled plastic, EPICBOOM showcases an all-new, innovative, oval design that makes loud, 360° bassy sound more portable, unleashing an unexpectedly big sound for its size. You just need to set up once, it will remember each other and automatically double up your sound next time.LAUSANNE, Switzerland & SAN JOSE, Calif.-( BUSINESS WIRE)- Ultimate Ears, a brand of Logitech (SIX: LOGN) (NASDAQ: LOGI), today announced the addition of EPICBOOM to its lineup of beloved portable Bluetooth ® speakers. The app will require you to connect to the second speaker by pressing twice on its Bluetooth button. Here we will just use the Double Up feature. The app is very clean and easy to use, you can also use this app to change Equalizer settings and set alarm. Then I installed the UE BOOM app which can be found on Google Play or App Store. I connected the first speaker via Bluetooth and it acts as a master speaker. That is the Double Up feature which allows wirelessly connecting two BOOM units to double the sound.īasically, you will need two BOOM speakers to try the feature. In the review, I mentioned an interesting feature that I didn’t have a chance to try. It is water and stain resistant, it has a portable design that you can bring anywhere, its battery life is almost the longest one and its sound quality is better than all wireless speakers at the price range. Not long ago, I reviewed the UE BOOM speaker and it is still my favorite wireless speaker so far. ![]() In that paper, they proposed the iconic double-helix model of DNA as we now know it, with sugar-phosphate sides and rungs made up of A-T and G-C base pairs. Armed with the information that DNA was a double helix and previous reports that the bases adenine and thymine occurred in equal amounts within DNA, as did guanine and cytosine, Watson and Crick published a landmark 1953 paper in the journal Nature. In 1953, Wilkins showed the photo to biologists James Watson and Francis Crick - without Franklin's knowledge. Franklin documented this structure in what became known as Photo 51. In 1952, chemist Rosalind Franklin, who was working in the lab of biophysicist Maurice Wilkins, used X-ray diffraction - a way of determining the structure of a molecule by the way X-rays bounce off it - to learn that DNA had a helical structure. (The term "nucleic acid" derives from "nuclein.")īut for many years, researchers did not realize the importance of this molecule. Miescher used biochemical methods to isolate DNA - which he then called nuclein - from white blood cells and sperm, and determined that it was very different from protein. (Image credit: Universal History Archive/Universal Images Group via Getty Images)ĭNA was first observed by Swiss biochemist Friedrich Miescher in 1869, according to a paper published in 2005 in the journal Developmental Biology. Rosalind Elsie Franklin (1920-1958) was a British chemist and crystallographer who is best known for her role in the discovery of the structure of DNA. But there is some natural variation in the number of sex chromosomes people carry - sometimes, there may be extra sex chromosomes, or one might be missing, so other patterns, such as X, XXX, XXY and XXYY, can also occur, Discover reported. In general, females carry two X sex chromosomes in each body cell and males carry one X and one Y. Most chromosomes look like microscopic Xs that said, humans and most other mammals carry a pair of sex chromosomes that can be either X or Y-shaped, according to the National Human Genome Research Institute. Humans have 23 pairs of chromosomes, which are found inside each cell's nucleus, the control center of the cell. Each chromosome contains a single DNA molecule, wrapped tightly around spool-like proteins called histones, which provide chromosomes their structure. To fit inside cells, DNA is coiled tightly to form structures called chromosomes. Freeman and Company, 2002).ĭNA molecules are long - so long, in fact, that they can't fit into cells without the right packaging. This RNA copy, called messenger RNA (mRNA), tells the cell's protein-making machinery which amino acids to string together into a protein, according to " Biochemistry" (W. Then, an enzyme zooms in and constructs a new RNA molecule whose sequence mirrors that of the unzipped gene. In addition, while RNA has three of the four nitrogen bases in common with DNA, it uses a base called uracil rather than thymine to pair with adenine.Īs a cell prepares to build a new protein, its DNA unzips to expose one strand of the gene with the instructions to build said protein. RNA shares a similar structure to DNA, except it contains only one strand, rather than two - so it looks like just one half of a ladder. To make a protein, the cell makes a copy of the gene, using not DNA but ribonucleic acid, or RNA. The shorthand for this process is that genes "encode" proteins.īut DNA is not the direct template for protein production. Similar to the way that letters in the alphabet can be arranged to form words, the order of nitrogen bases in a DNA sequence forms genes, which, in the language of the cell, tell cells how to make proteins. The scientists detailed their findings online April 26 in the journal Nature Communications.įollow us on Twitter Spacedotcom and on Facebook. In addition, imidazole can act like a primitive catalyst to set off chemical reactions, such as forming purines instead of pyramidines. Imidazole and similar molecules proved far more abundant than pyramidines in these meteorites, suggesting they might prove easier for naturally occurring chemical reactions to synthesize. Oba suggested a clue might lie in the fact that purines include a pentagonal ring known as imidazole, whereas pyramidines do not. ![]() It remains uncertain why pyramidines were so much less abundant in these meteorites than purines. "Due to our findings, we can say nucleobases also show wide varieties in carbonaceous meteorites," Oba said. Scientists find liquid water inside a meteorite, revealing clues about the early solar system Too much of a good thing: Early impacts delivered iron to Earth but almost wiped out life Your RNA may have come from space, meteor study suggests Areas which are pure green, only darker than the background are magenta. The treshold sliders are now quite randomly set. The next one is a more realistic result - the background is mixed with the target in a complex way. The process: The green can be turned to transparency by applying Colors > Color to Alpha. To stay in truth your colored stripes would be recovered quite well with the next process because the programmer has thought in same way as you - like the unwanted color is there only due transparency. You need something much more advanced than GIMP if you want some guessing ability. It sees only the mixing result pixel by pixel with no idea what kind of common creation process could be behind different pixels. ![]() Actually you didn't guess, you constructed the stripes that way, but a dumb automate with no AI cleverness cannot know how an image is constructed. In your image of "what should be done" you guessed that the horizontal color stripes continue with the same hue and saturation, but the transparency increases as the color moves closer to pure green. Unfortunately there's no way to calculate exactly the original color of the mixes areas because we do not know is it mixed due the transparency (= more transparent hairs near the edges) or was it originally with no green background colored to more green at the edges than in the middle of the scalp. Obviously your scalp with green background presents well your problematic images - large areas where the green is mixed with hair: Even with the simple function, I understand what it's saying, but I would not know how to perform it using simple selections and channel manipulation. Given all this undefined behaviour in the problem space itself, I'm sure Adobe Premiere and all the other professional video production tools contain very sophisticated chroma keying algorithms.Ĭan we even approximate the result of those algorithms using basic image manipulation, as found in Gimp? Or is any such endeavor bound to fail?Īlternatively, is there an open source Gimp plugin or separate program that can perform a good quality chroma keying on pictures?Įdit: Wikipedia's article gives an example of a simple function for green screen: rgb(r,g,b) -> rgba(r, min(g,b), b, A*(r+b)-B*g) and goes on to explain that modern algorithms can be much more complicated. ![]() For instance, the color that lies exactly between the key color (green in this case) and its exact opposite (which would be magenta in this case) is a perfect gray (by definition of opposite color.) Do we need to turn that shade of gray into semi-transparent magenta? What if it was an actual gray in the original picture? (Which is actually more likely.) I don't know the theoretical background behind chroma keying and I'm guessing it could be quite hairy. ![]() You can not turn a shade of green into semi-transparent red, and another shade of green into semi-transparent blue, just by fiddling with the magic wand, the color selection tool, or by copying a channel into a mask. The reason I posted this question is that all other questions and answers about this topic miss this crucial point. Meaning, if the key color is green, all greenish colors need to be substantially modified, in addition to having a suitable alpha channel added: Notice how this procedure is not merely adding an alpha channel it is changing all colors that lie in the same quadrant as the key color itself. If we look at what needs to be done (or approximated as far as possible, see below) it is the following: (Note: I don't know how to do it yet, this mockup was made starting from a stock transparent picture.) Is it possible to apply chroma keying, meaning to remove a green (or blue.) screen background, using Gimp? (I happen to use Gimp, but I suppose an answer using Photoshop would be just as good, unless it's referencing a specific Photoshop plugin.) enable to mix and match to meet mission requirements." Aurora relied on 3D printing to verify design schemes, scaling those designs for the demonstrator. "A lot of aircraft simply fly fast or can fly like helicopters but to bring them together so aircraft can do both, with the intent of advancing technology, to increase the industrial base, to exploit new design tools and materials, to exploit new configurations. "It became apparent that rather than focusing on a particular mission set there was a great advantage to pushing technology to encourage development of new design spaces," said Ashish Bagai, the program manager at DARPA’s Tactical Technology Office supporting the XV-23A program. With only five minute endurance, the demonstrator was able to validate a number of key technologies for the full-scale aircraft, including the tilt wing/tilt canard configuration, aerodynamics, avionics architecture, flight control algorithms and software. A 20 percent subscale vehicle demonstrator of the XV-24A LightningStrike Vertical Take-off and Landing (VTOL) X-Plane completed its planned flight test program in early March at Webster Outlying Field in Southern Maryland. NATIONAL HARBOR, Md. - Aurora Flight Sciences, in partnership with the Defense Advanced Research Projects Agency, is one step closer to developing an unmanned aircraft with the speed of an airplane and the agility of a helicopter. ![]() If you prefer a small footprint, our small wristlet wallets are super sleek with plenty of slots and a zip pocket, perfect for an evening adventure.
