“The challenge isn’t in the hypersonic phase,” said Viola. But one of the biggest sticking points wasn’t so much to create an aircraft that could fly fast, but rather to design one that could also fly slowly. The STRATOFLY design came with plenty of technological challenges. The goals are aligned with national, international and business priorities. The EU is funding numerous research initiatives covering a range of fundamental technologies, including hydrogen-related ones, to make aviation safe, efficient and clean. While these technologies might take many decades to enter service, it’s important to dream big now, according to scientists. Still, in the worlds of civil aviation and research, ambitious ideas persist to make faster and cleaner airplanes. Recent EU regulatory initiatives, including a new law to cut aviation emissions, have highlighted the political skepticism in Europe by limiting incentives for supersonic commercial flights. In the meantime, the political appetite in the EU for supersonic passenger air travel has waned in large part because of environmental concerns, not least noise and emissions of pollutants that cause climate change. The project focused on innovative ways of powering an aircraft able to carry 300 passengers. STRATOFLY designed a prototype in the form of a computer model for a hydrogen-fuelled hypersonic plane. But I’m sure that I will see a hypersonic airliner in my lifetime.” “Maybe we’re not ready yet for Mach 8 right now. “It’s going be a real challenge,” said Nicole Viola, who coordinated STRATOFLY and is a professor at the Polytechnic University of Turin in Italy. STRATOFLY, which ran from 2018 to 2021, built on three previous EU research projects in the field. That’s what the EU-funded STRATOFLY project proposed: a Mach 8 airliner - a hypersonic aircraft that can go at least 9,500 kilometers (5,900 miles) per hour, or about eight times the speed of sound. So the question arises: will people one day be able to count on flying from Paris to New York in less than an hour without contributing to global warming? Sky-high ambitions The following is captured image of safety and disinfection campaign videos currently playing on our products installed in Seoul Metro.Traditionally designed for efficiency and safety, passenger planes are now increasingly being developed with climate neutrality in mind as well. In addition, content suitable for each customer and site is uploaded easily and conveniently via this platform. Via the IoT platform we developed, all WeClean products around the world are monitored in real time, and the disinfectant spraying cycle is also controlled remotely. The fact that cleaning alone reduces germs can also be seen in the guidelines of health organizations such as WHO.Īs an automatic sterilization cleaning product exclusively for handrails, with 99.99% sterilization effect proven by numerous actual field test reports and regular cleaning function that does not require additional beautification personnel, WeClean is also a smart device equipped with IoT function. WeClean’s patented 3-tier cleaning roller rotates in the “reverse & forward” direction according to the rotation of the handrail to clean every nook and cranny of the surface. In addition, the trouble of cleaning the handrail surface every time even after installing the sterilizer is solved with WeClean’s 3-tier cleaning roller. WeClean not only performs the same human spraying and wiping of the disinfectant, but also can set the disinfectant spraying cycle from 1 to 60 minutes, so the handrail can be continuously sterilized throughout the operating time. The photos above show the cleaning staff and staffs manually disinfecting the handrails, the customer contact point, using disinfectant and rags.Īs the number of management targets increases, the problem of management manpower and input time, and the amount of work will naturally increase.Īnd another important point is the continuity of disinfection, which can be said to be a gap in manual disinfection.Īll of these problems can be solved by applying our WeClean.Īll of the WeClean models installed this time are S200G, hybrid premium self-generation type that performs disinfectant spray and UV advanced oxidation process at once. Seoul Metro, which transports an average of 7,469,180 people a day (2019), has been disinfecting and cleaning the escalator handrails 4 times a day since Corona19. Due to the unprecedented COVID-19 pandemic, surface disinfection of many public facilities is mandatory.

Lastly, you can turn to archiving to add an extra layer of security to sensitive files. It’s well-known that online transfer services come with a limit and if you compress files before sending them, you will be able to work less.įile compression and archiving are helpful if you simply want to save disk space on your Mac, especially for files that you don’t use that often. Another situation occurs when you try to transfer large files online. Well, if you compress the attachment first, you will be able to send it over the email. First of all, you’ve surely been in the situation where you wanted to attach an image or video to email only to get an error saying that the file is too big. There are numerous reasons why using a Mac file archiver to compress files makes perfect sense for users. Why Is It Important to Compress Files on Mac? And while RAR offers better compression rates, they lack archiving speed or the ability to split the archives in multiple volumes. The biggest rival for ZIP archive formats, RAR is another extremely popular one. Ever since ZIP and GZ archive formats appeared, TAR lost some of its traction but is still used by classics. IT’s basically a series of blocks with a specific amount of bytes attached to each block. TAR is another of the popular archive formats you will find in pretty much any file archiver Mac software. It’s widely used on macOS, Linux and Unix and the open-source format makes it very accessible. It combines the GZip compression method with lots of archiving techniques for excellent results. GZ is one of the formats that are gaining a lot of popularity in recent years. When you choose the best file archiver for Mac you need to take into consideration the formats it handles. Despite the exceptional speed, ZIP doesn’t offer the best compression rate for files. This allows archivers to deliver exceptional speeds and an overall easy operation. Zip files are extremely versatile and their strength comes from the ability of compression files together or go file by file and applying compression on specific ones. It’s one of the most common formats out there. However, we’re checking the ones that are used the most: As you know, there are hundreds of formats available out there and new ones are being developed daily. Now that we’ve checked some suggestions for the best archiver for Mac title, it’s time to look closer at the most popular archive formats around.

We did a comprehensive free Windscribe VPN review and were pleasantly delighted to discover that the only limitation is the amount of data you are given – otherwise, the free VPN is very much a near-premium service. However, this does appear to be an isolated incident in an otherwise clean security record. Windscribe evidently failed to encrypt this server between 20. What is Windscribe Double Hop, and how does it work? It’s the ability to achieve double encryption and increased anonymity in return for slower performance by using a VPN on your desktop and another VPN through a browser extension.īut is Windscribe safe? Back in 2021, Two VPN servers were confiscated in Ukraine, and the recovered disc had an OpenVPN private key that could have been used to impersonate a Windscribe server and intercept communications. The Windscribe Double Hop option provides additional protection when using your browser. Every session generates a new key, so even if your old one was cracked, it would be worthless by the time you started a new one. A SHA512 algorithm and a 4096-bit RSA key support this encryption even further.īecause your data is encrypted into random characters, any device other than your own will be unable to read it. Windscribe, like most other top VPN services, uses AES 256-bit encryption to provide military-grade protection. The stealth protocol is an additional protocol based on OpenVPN that is particularly good at circumventing VPN restrictions in countries with strict internet regulations. We also tested IKEv2, since it is the default protocol at Windscribe, and only noted slight increases in performance. As our tests moved to locations much further in distance, we averaged around 18 – 20 Mbps. Local servers should have been close to our maximum bandwidth, but they were not even close. We connected to several local servers using a consistent 160 Mbps internet connection and, on average, could only reach about 25-28 Mbps. During our Windscribe review, the OpenVPN protocol was heavily tested due to its popularity and security benefits. Several protocols were confirmed during our Windscribe VPN review, and they were nothing out of the ordinary – OpenVPN, IKEv2, WireGuard, and Stealth. For those who need to know whether Windscribe is good but are in a hurry, we’ve got a quick pros and cons list to check out. We understand that some of our readers are incredibly busy and won’t have time to read the depth of our Windscribe VPN review. One security disadvantage of being able to provide true geo-located servers is that many of them are rented rather than owned by Windscribe – which means some security is left to third parties. Windscribe servers, with the exception of Fake Antarctica which is actually located in Canada, are situated in their respective nations rather than virtual locations, unlike even some major VPN service providers. During our Windscribe review, we discovered more than 170 servers in 63 countries, including one that provides an IP address for Troll Station in Antarctica – although this is a bit of a gimmick rather than a useful server.Īlthough this isn’t a large number of servers – other VPN services such as Private Internet Access have more than 30,000 – it nevertheless provides excellent coverage for the vast majority of customers. When it comes to server coverage, is Windscribe a good VPN? Their coverage is, without a doubt, excellent.

The trailhead parking lot has a parking fee. You will see the Carson Ranger station and the parking lot on the left hand side. Stay on 88 until you come to the top of Carson Pass. When you come to the 89/88 interchange, turn right onto Highway 88. This hike is around 6.5 miles with a 2,300 foot elevation gain, but you can extend it by heading down into the beautiful canyon that holds Fourth of July Lake which is surprisingly empty around Fourth of July.ĭirections: From South Lake Tahoe, take Highway 89 south through Meyers and continue south. From the Carson Pass on Highway 88, you can access the trail and hike in the forest from little Frog Lake, to Round Top Lake to Winnemucca Lake. It also supports huge blooms of spring and summer wildflowers, and expansive views of the lakes and mountains in the Mokelumne Wilderness south of Tahoe. This is another great hike that doesn't have a view of Tahoe, but has an interesting variety of terrain. Winnemucca, Round Top & Fourth of July Lakes - South Lake Tahoe It's tough by the payoff in views is spectacular.7. Check the weather, allow lots of time (some of the trail can be hiked at 25 minutes/mile, other sections may take nearly an hour a mile), and take plenty of water. 2 mile to the top.but the trail ends 200 yards below the top.you have to scramble over boulders without any trail to ascend to the very top. Tallac" with an arrow pointing the way to the last. The Glen Alpine Trail begins near Fallen Leaf Lake on the southwest side of Lake Tahoe, climbs steadily past Susie Lake and Heather Lake to the shores of. At the saddle, the trail turns toward the top of the mountain which is several more hundred feet in elevation and roughly 1.1 miles further to "the post".a signpost "Mt. 3/4 of a mile from the flat "saddle" along the Tallac ridge begins a harrowing hike across angular irregular boulders that requires good balance and steady feet. But once you leave Cathedral Lake the trail becomes very steep and rocky. The first 2.7 miles takes you to small Cathedral Lake with a trail that's moderately steep and rocky in places. The hike is tough, but the views are spectacular.of Lake Tahoe, Fallen Leaf Lake and the mountains surrounding the Tahoe Basin. It's a 3000' elevation gain through wooded forest at the lower levels, and across long rugged boulder fields at the higher elevations. In fact, it's about 5.7 miles so be prepared. The US Forest Service map says it's 4.7 miles to the top of Mt. A local also commented his friend had to call for search and rescue when attempting this hike. Other hikers I met as I descended from the summit also said the trail was not well marked. The hike goes from pine forest, to rocks and boulders, and then to meadows with scattered trees.īut again the hike can be frustrating. I also appreciate how the hike changes with elevation. Definitely something I would have expected from a national park or world heritage site. What I appreciate about this hike are the views from the top. Similar to section 2, I found previous hikers set up their own guideposts such as a ribbon on a tree. In section 3 the hiker will pass by groups of pine trees. I also disagree with other online reviews saying the trail is exposed once you leave the pine forest (section 1). In section 3 the hiker leaves the boulders and enters an area of meadows with scattered pine trees. The area is often wet early in the summer since Cathedral Meadow is located near Taylor Creek and Fallen Leaf Lake. Hike there during the warmer months, and then snowshoe and cross-country ski in the snowy ones. But there are no official markers such as red dots every 100 meters. Hiking Cathedral Meadow (via SR 89 near Fallen Leaf Lake in South Tahoe) Cathedral Meadow is accessible year-round. Previous hikers set up cairns as guideposts. Some of the rocks are unstable and reading the trail becomes difficult. Section 2 is the most technical part of the hike. In section 2 the hiker leaves the pine forest and ascends up rocks and boulders. In this section the trail is well marked and easy to follow. In section 1 the hiker goes through a pine forest passing by 2 small lakes and a grand view of Fallen Leaf Lake. I see the hike up to the summit in 3 sections. Even on my second attempt I had to double back three times to find the trail. Start point: Fallen Leaf Lake Trailhead End point: Lacamas Lake (one option) Hike Type: In and out with loop Distance: 4. It took me 2 attempts to reach the summit. Contrary to what others have posted online, I found the trail was not well marked. Today is, I am demanding not only an apology.but GMC pay for my time. I will not purchase or refer any of my family and friends to GMC, I would not want anyone to relive my nightmare. Why would GMC knowingly sell me a Truck that has all these issues? Why still to date would it be hard to get someone on the phone in 2023? I wish there was a term past Unacceptable. No one from GMC has called me with an apology.not a Supervisor, Manager or any VP. I've called Corporate several times to file a Claim. This has been tasking, overwhelming and has made me and my Wife very upset. This is unacceptable.this has cost me time and money. In the past year I've only had my truck 3 months. GMC had my truck for less than 24hrs and found none. I first addressed issues with my Truck only a couple of weeks after purchase. The 02 sensors has failed, two different Pipe issues were addressed (Item number ******** & ********), a Gasket was replaced, injector Kit & Catalytic Converter replaced. GMC sold me a Lemon! I want a new truck! A couple of weeks after purchase and within the last year I've had the following trouble with my NEW 2022 GMC SIERRA TRUCK. To Whom It May Concern: I purchased a 2022 GMC Sierra Limited in January of 2022. I took my vehicle to freedom Chevrolet ed Morse on 1/13/23 for a problem I had with my truck which it was idling rough and possible shut off while parked.I was originally told that I would be able to get a loaner and that didn't happen.The diagnosis was a solenoid which for parts and labor cost me roughly $1200.I didn't have the money so they recommend a loan that I could get just to cover that.I was approved for the loan and the repairs was done I thought.I picked my truck up on a Tuesday the following week just to learn that I had the same issue.I returned my truck that following day.When I arrived I spoke with the gm name *** whom assured me they would get to the bottom of the repairs and he will get in touch with me.I never heard from him.The only time I received updates on my vehicle is when I called to check.When I did call to check on my vehicle I was told it was the exhaust pipe that needed to be replaced and they did that free of charge just to learn that wasn't the problem either.I feel they replaced parts that didn't need to be replaced and charge me $1200 for nothing.I wasn't offered a refund nor an apology for the inconveniences.This place is a total scam and I wouldn't recommend the devil to this place.The only person that kept me sane was the service agent Quentin.At this point I don't if the repairs was done are not are if I'm to have problems with my truck in the future.My truck is a 2020 GMC Sierra which is fairly new and I trusted the place with my vehicle just to be disappointed all the way around.NEVER trust this establishment they will rip you off and think nothing about it.Out of all of that the problem turn out to be a screw was loose on the air filter housing.
