Suspended chords AKA ‘sus chords’ are simply Perhaps this is easier to understand in a simple chart: ChordĬ Minor (1st Inversion): /wp-content/uploads/2020/03/C-Minor-1st-Inversion.mp3 C Minor (2nd Inversion): /wp-content/uploads/2020/03/C-Minor-2nd-Inversion.mp3 Suspended chords. Leading’ each respective chord is C, G, Eb. In the image above, we can see the default triad, 1st inversion and 2nd inversion. This has the effect of changing which note is at the root of the chord. It can seem a bit confusing, at first, but it’s super useful when you get your head around it!Īs discussed earlier, ‘inversions’ are ways of playing the same chord but with one or more of the same notes played You can choose which ‘version’ of the chord Of the root chord – or, as we call it in music theory, an ‘Inversion’. The lower G is one whole octave below the higher one.ĭo you see that this is an example of the same chord with the one played on a different octave? This is a ‘version’ G is 5 semitones down from C, and therefore 7 semitones up from Remember that an octave is made up of 12 semitones? In the chord of C Minor, the fifth is G. wp-content/uploads/2020/03/C-Minor-Diatonic-Scale-chords-played-in-Play-window.mp4 You can add complexity too, and even play C Minor (and all the chords in its scale) with one finger!

The 1st and 5th notes are the over-arching chord tones. The middle note, or third, is what signifies whether a chord is Major or Minor. That means the pianist’s hand is less stretched when playing a chord With 12 notes in a chord, chord tones more than five semitones away can often be accessed with a smaller leap by ![]() That means, we try and keep the distances between notes from chord to chord as low as possible. When playing from one chord to the next, we at Captain Plugins generally try and minimize the leap for a pianist.

How To Install Your Topaz Labs Program Into Lightroom Classic Cloudmounter itunes2/3/2024 ![]() More concerningly, my tests showed that decryption did not always, you know, decrypt. I confirmed that a batch of non-Google Docs files encrypted on my Google Drive were showing up as indecipherable gibberish, even when I checked them via the Web. I'm honestly not sure why you'd need to, though. Once a drive or directory is encrypted, you can further lock or unlock it with the same password you used to encrypt it, preventing any additional alterations. If you forget one, you'll have to manually look it up in the Keychain Access app, where it'll be stored not under "CloudMounter," but under the name of the particular drive or directory you've encrypted. You also can't use the Keychain to retrieve passwords from within CloudMounter. You have to enter it twice to find out whether you've accidentally incorporated any typos. There's also no way to see the password you're typing. (A handful of files took two to three minutes if you're encrypting or decrypting big chunks of data, expect a long wait.)ĬloudMounter doesn't make it easy to create passwords though you can add passwords to the Keychain, you can't use its ability to suggest new passwords the way you can in web forms. ![]() Right-click any folder on your CloudMounter drives, select Encrypt from the pop-up menu, choose a password, and wait a few minutes while CloudMounter chugs through its 256-bit encryption scheme. This great idea, in theory, might need a little more polish in practice.Įncrypting and decrypting whole drives or directories - you can't encrypt individual files – works simply enough. It can scramble any non-Google files on your remote storage so that anyone not using your particular copy of CloudMounter sees only gibberish files - even when logging in via a web interface. Tales From the EncryptedĬloudMounter prominently boasts of its encryption abilities. I downloaded it using Google's web interface, where it remained perfectly intact, deleted it from the cloud, re-uploaded it, and a second download worked fine. One PDF file I downloaded from my Google Drive just wouldn't open, citing file errors. Google Docs files are their own proprietary format, so you won't get much out of copying them to your desktop. I only experienced a few bumps when moving files back and forth. You can see all your drives, and mount, unmount, or encrypt them, or display them in the Finder, via the discreet CloudMounter icon up on the right side of the menubar. Nifty little icons next to their file names in the Finder show you whether they're uploading, downloading, etc. Dragging files to and from them felt seamless, and uploads took no longer than they do for iCloud – and often felt much shorter. Once setup and mounted, those drives worked like any other on my Mac. CloudMounter works with a whole buffet of services and technologies, including Dropbox, Google Drive, OneDrive, Box and more. 275 60r20 goodyear trailrunner a t2/3/2024 Overall, the Goodyear TrailRunner AT is light-duty, comfortable, fuel-efficient, and attractive.

Ufish south prairie2/2/2024 ![]() ![]() As part of the funding application process, we have contracted with an impartial third party to perform a focused household income survey of the residents of our wastewater system. The primary harm is to the reputation of our senators, who showed how willing they are to dance to the tune of a handful of wealthy cattle barons and oil boys.Town residents will be receiving several mailings from RCAC (Rural Community Assistance Corp.) regarding a median income study. If the House passes the measure, which is likely, President Joe Biden will probably veto it, with no immediate harm done to the birds. “As they say in Kansas, don’t pee on my boot and tell me it’s raining.” “Indeed, because animals famously love it when their habitats are potentially endangered so some humans can make a quick buck. “You kept them from being protected you weirdo.” The reactions were better than the tweet, including: He tweeted a GIF image of a prairie chicken in sunglasses with the reality-defiant caption, “It’s a good day to be a lesser prairie chicken.” Marshall’s end zone dance was particularly egregious. to service drilling rigs in prairie chicken mating grounds, because the birds only do the chicken dance early in the morning. ▪ Oil and gas producers, for about three months of the year, would have to wait until after 9:30 a.m. ▪ Ranchers would have to follow a scientifically approved grazing plan, so their cattle don’t overgraze the prairie and destroy the birds’ habitat. ▪ Farmers are essentially unaffected because prairie chickens avoid cropland, so farms are exempt from protective regulations. No word yet on how Moran intends to make it rain, except possibly campaign contributions.Īnd what the senator calls unnecessary consequences? Most anyone else would call them minor inconveniences, if that: “Listing the bird as a threatened or endangered species is not the answer - plain and simple, we need more rainfall, not more regulation.” “Today, the Senate acted to protect farmers, ranchers and producers from the unnecessary consequences of listing the lesser prairie chicken,” Moran said. And Wednesday, they got what they wanted. The oil and ag industries have been pushing our senators, Roger Marshall and Jerry Moran, for this for years. “It’s heartbreaking that 50 senators care more about lining the pockets of industry cronies than saving an irreplaceable piece of natural heritage in the West.” “The senators who voted to use the Congressional Review Act to nullify protections for the lesser prairie chicken voted to condemn this bird to extinction,” wrote Stephanie Kurose, senior policy specialist at the Center for Biological Diversity. Fish and Wildlife Department’s designations for two population groups of lesser prairie chickens - in west Texas and New Mexico, where they’re listed as endangered and in Kansas, Oklahoma, Colorado and North Texas, where they’re in the slightly less dire category of being a threatened species. On a 50-48 vote, the senators rejected the U.S. On Wednesday, the Senate approved the unprecedented action of using the Congressional Review Act to remove federal protection from a species of wildlife. ![]() As indifferent as I am to the mating dance of the prairie chicken, it’s been tough to stomach the mating dance of the ag/oil industrial complex and our two Kansas senators, who did their bidding at the U.S. Drifting lands rciew2/2/2024 ![]() One of my favorite things to see as a gamer is when a developer tries to switch up a genre and manages to nail the approach just right. You can also Follow Technobubble poobah Jason Hidalgo’s shenanigans on Twitter or his Tabiasobi Youtube channel. I’m not sure if I can look at shmup games the same way again after Drifting Lands.Technobubble covers games, gadgets, technology and all things geek. The grind for loot will grab you and you’ll want to spend hours getting your ship calibrated to the way you play. They didn’t feel cookie cutter and had a voice even though there were no animations, you could picture the movie in your mind.ĭrifting Lands should be on the radar for any shmup fan, with the addition of the action RPG elements it adds great replay value and pull in non shmup fans. Without spoiling too much of the story you do run into a diverse group of characters each with their own moral drive and feel. That part really opened up the whole story telling and overall wasn’t that bad! Each cut scene was just a backdrop of the area you were in and the image of the character speaking, no animation or CGI cut-scenes here. Each level is mission based and you can choose to do side missions to be able to get more epic items or much needed money. In the story of Drifting Lands you’re a pilot that gets caught up in the politics of the Ark and needing to protect it. The background and colors are vibrant and pop right at you creating some great depth. The artwork is gorgeous, and everything feels so open even though it is a 2D side-scrolling shmup. Also the soundtrack was fun and exciting during the missions. I didn’t run into any major problems playing the game or anything that really annoyed me. Depending on your ship Focus is gained in different ways and there are 10 levels of Focus, the interceptor needs to graze enemies bullets, the marauder has to sit within a shiny vortex as long as it can, this vortex will move around after a couple of seconds, and lastly the sentinel gains Focus when its shield is recharging…meaning you actually need to take some damage to build Focus. There is also another element of gameplay that pays a huge role in getting a better score and used in some of the more advanced skills, Focus. You can tailor your skills and attributes to your style of gameplay and you’ll be kicking ass in no time. Everyone will play this game differently and that’s where the ARPG (action rpg) comes into play. Also as in most shmups the bullet spreads and movements can be recognized as patterns so you’ll need to pick up on those quick to be able to get yourself out of a tight situation. They rank as smaller and quicker, to slower and tankier in that order. The interceptor, the marauder, and sentinel. There are three ships to choose from each with their strengths and weaknesses. The idea is the same as in all shmups, try to kill everything that moves while not getting killed in the process. You can use either a keyboard or gamepad to control your ship, with the gamepad being the easiest to use. It’s a horizontal side scrolling shmup in using my earlier example of Gradius, it plays the same way. In other words…don’t be afraid to sell the crap out of things so you can get yourself stronger. You also need it to invest in your base attributes, Structure (Health and Armor), Power (Health and Skill Power), Navigation (Health and Weapon Damage). Unfortunately these aren’t the only thing you use your hard earned cash on. Once you have unlocked these skills you can then invest more money into leveling these skills up. Some are passive skills, most are damage and a few support skills like healing or regenerating health. Once you get enough money you can start investing in skills for yourself. ![]() You can also sell them or even for a price convert them into a blueprint to see if you can get a better bonus off of that part. If you do survive, and hopefully you do, you can go into your hangar and put those shiny new pieces on your ship. ![]() None of which that you can use right away and have to survive to be able to utilize any of your hard earned loot. So instead of racing to get the powerup across the screen you race towards credits, parts, and blueprints. It takes a hold of the action RPG element of having loot drop and makes it work. The majority of shmups are similar in the way you get stronger in your journey, you pick up powerups within the level and hope to not get hit or not die so that you’d lose those powerups. The people at Alkemi somehow mixed the genre of action RPG into a shmup, and not only that but added a decent story with somewhat interesting characters. I’ve been wasting some time with the classic Gradius recently so I was fully ready to embrace the shmup side of things….My body was not ready for this. Upon starting Drifting Lands I wasn’t too sure what to expect. Csr racing 2 hacks ios2/2/2024 ![]() Keep an eye out for events to earn extra cash for upgrades and win rare parts for your rides.

![]() However, while there are numerous radio temperature measurements of the quiet-Sun atmosphere, there are very few for sunspots, particularly at millimeter wavelengths, since good spatial resolution is required to isolate the brightness temperature of the sunspot from its surroundings, and single-dish measurements generally do not have enough resolution. The temperature, at which a given frequency is optically thick, is sensitive to density and temperature, and hence the radio data provide important constraints for modeling (e.g., Loukitcheva et al. ![]() The radio data are particularly valuable for solar diagnostics because the measurements are in the Rayleigh-Jeans limit, meaning that measured brightness temperatures actually represent thermal electron temperatures in the optically thick atmosphere. 1986 Obridko & Staude 1988, for a review see Solanki 2003) and, when available, radio measurements of brightness spectra, together with ionization equilibrium and radiative transfer calculations that include heat transfer down from the corona as well as other factors (e.g., Fontenla et al. Deriving such models is a complicated process that tries to balance observations of a range of optical and UV lines (mostly formed in non-local thermodynamical equilibrium (LTE) conditions, see, e.g., Avrett 1981 Maltby et al. There have been numerous attempts to build a comprehensive semiempirical model of the atmosphere above a sunspot umbra. Key words: Sun: chromosphere / Sun: radio radiation / sunspots Better spatial resolution as well as better wavelength coverage are needed for a more complete determination of the chromospheric temperature stratification above sunspot umbrae. A successful model that is in agreement with millimeter umbral brightness should have an extended and deep temperature minimum (below 3000 K). These data impose strong constraints on the temperature and density stratifications of the sunspot umbral atmosphere, in particular on the location and depth of the temperature minimum and the location of the transition region.Ĭonclusions. Current mm and submm observational data suggest that the brightness observed at these wavelengths is low compared to the most widely used sunspot models. These are compared with the umbral contrast calculated from various atmospheric models of sunspots. We use observations of the temperature contrast (relative to the quiet Sun) above a sunspot umbra at 3.5 mm obtained with the Berkeley-Illinois-Maryland Array (BIMA), complemented by submm observations from Lindsey & Kopp (1995) and 2 cm observations with the Very Large Array. The aim of this paper is to demonstrate that millimeter wave data can be used to distinguish between various atmospheric models of sunspots, whose temperature structure in the upper photosphere and chromosphere has been the source of some controversy.
