With The Somewhere Project, Bernstein would be most thrilled about seeing so many different factions-people from different demographics, of different ages-involved and participating. What do you hope people take away from this production of West Side Story, as part of The Somewhere Project? I think that’s why it’s so important not to shy away from issues of our time, but to really challenge them-full force-yet be willing to look at them with an open constitution. We can explore feelings and issues, while being in a protective cocoon of creating. That is the thing about art: Art can protect us. The Somewhere Project is so compelling for me and feels so close to my heart because it brings together my adoration and love for this man, Leonard Bernstein, with this idea that story and music can change the world. What opportunities does The Somewhere Project give you personally to build the world you imagine? Video: Marin Alsop on the influence of Leonard Bernstein You want to feel that there’s a person for you, there’s a place for you, there’s a group for you … and there is. “There’s a place for us,” and I think everyone wants to feel that. That conflict resolves-albeit temporarily-when we finally arrive at the song “Somewhere.” We have this moment of true introspection and true questioning, but also a sense of belonging. Bernstein used the interval of the tri-tone-which used to be called the “devil’s interval”-to illustrate and embody conflict. While the story is extraordinarily compelling, the music of West Side Story has its own narrative. What makes West Side Story such an enduring work? I think in the end, the moral of allowing love to prevail is one that is a great lesson for all humankind. There’s so many things that resonate so sadly with us right in this very moment of history. I think the themes and the moral of West Side Story are what really resonate with us, even today: the themes of youth and independence, wanting to be your own person, making your own decisions, but being hampered by conflict and prejudice. What elements of West Side Story resonate most personally for you? We need a beginning, we need a middle, we need an end most important, we need a moral to the story. He was always inventing stories because he understood that we, as human beings, needed a story. If he didn’t know the story of a piece, he’d make it up. One of the most valuable things I learned from him was this idea of telling stories through music. Maybe each of his students felt that way-that was his gift. He exceeded all of my expectations-he was so generous, so loving, and so caring of all of his students, but I felt especially of me. One of the greatest experiences for me was becoming a student of Bernstein’s in my late 20s. It was about sharing his excitement about this great experience-one that he wanted everyone to have. For him, it was such a compelling story-I think for all of us it is-but the way he spoke about it was with such incredible passion. I remember sitting way in the back just in awe of him, listening to him work with the musicians and the singers and talk about West Side Story. He later invited me to observe sessions as Bernstein prepared for what would be a famous remake of West Side Story. My father, who was the longtime concertmaster of the New York City Ballet Orchestra, knew how much I adored and idolized Bernstein. And from that day on, I knew I wanted to be a conductor. From the moment he came out on stage and began speaking to the audience, he shared his charisma and his obvious joy for what he was doing. I first saw Leonard Bernstein conduct when I was nine years old during one of his famed Young People’s Concerts. How has Leonard Bernstein shaped your vision for the power of music in people’s lives?

Also something else, undefinable but perceptibly troubled, even haunted. Once inside, reality quickly shone through her constructed shallow facade: a keen intelligence, a striking vulnerability. She attempted to micromanage the terms of our time together in sharp-elbowed fashion before agreeing to let me ride in her Stingray 1LT. I’d written a profile about Angelyne for THR in 2015. It had the aesthetic power and emotional resonance of genuine performance art, Marina Abramovic by way of John Waters, particularly as she kept on rambling around the city over the decades while she aged. Goldberg’s paper trail ends with their divorce in 1969.Ī portion of a name-change document filed in 2016 in Ventura County.Īngelyne had single-handedly created and then inhabited a modern myth of L.A.: the platinum blond bombshell in the bright pink Corvette forever circumnavigating the city, seeking to enchant by dint of her sheer superficial glamour. She’d have a brief marriage to the son of a Beverly Hills executive, living in Hollywood with him. She and her father moved from the Westside to Panorama City, deep in the San Fernando Valley, where she’d begin high school and Henry and Deborah would run a strip-mall liquor store in nearby Van Nuys. The next year Hendrik (now Henry) remarried another Holocaust survivor, a seamstress divorcee named Deborah, and Goldberg acquired a younger stepsister, Norma. Then, in 1965, her 44-year-old mother died of cancer. Her father worked as a tool-and-die mechanic. They boarded a ship leaving Haifa for New York and settled in L.A.’s Fairfax District. (A younger sister, Annette, was born in 1952.) So after Goldberg’s birth, the family immigrated to Israel, remaining in an ultra-orthodox community of Hasidic Jews called Bnei Brak, east of Tel Aviv, until 1959. They were eventually repatriated to Poland, which remained hostile to Jews after World War II. Shortly after liberation, she and Hendrik married in the Foehrenwald displaced persons camp in Germany. According to the documentation - obtained from the International Tracing Service, established by the Red Cross as an archive of Nazi crimes - her parents, Hendrik (aka Heniek or Henryk) Goldberg and Bronia (aka Bronis) Zernicka, endured unimaginable horrors at a series of concentration camps, first together at Skarzysko, where prisoners’ main job was to make munitions, and then apart at the 20th century’s most infamous hellscapes, including Buchenwald and Bergen-Belsen.īronia later submitted paperwork to Yad Vashem indicating she’d lost more than 40 relatives in the Holocaust, including her father, three brothers and a sister. 2, 1950, the daughter of Polish Jews who’d met in the Chmielnik ghetto during World War II - they were among 500 to survive out of a population of 13,000, the rest sent to death at Treblinka. Copies of immigration, marriage and death records pointed to a cloaked prehistory of Renee Tami Goldberg (originally Ronia Tamar Goldberg), which seems to reveal the trauma Angelyne had both emerged and escaped from.

LT button was moved at the center of the screen to let as much space as possible for the joystick and avoid touch mistakes. Then a shortcut is added on your homescreen and the application will be launched outside the browser.īecause it's difficult to spot the right place in a touch screen without looking at it, the touch zone of each button was increased. With only 3 clicks, virtual gamepads web application becomes a standalone application. With the add to homescreen chrome feature, you can easily use virtual gamepads application without launching the browser each time you want to play.

Use it as a Smartphone Application (Chrome for Android) your Raspberry Pi's IP address) on your choice of web browser (Chrome Mobile is recommended). Once the nodejs application is launched, you just have to plug your gamepad controller by connecting your device on the same local network and by reaching the address (i.e. Install from the experimental menu of the setup script (may only work well with a rpi2) Usage This project is the result of hard work from Miroof. Universal Controller Calibration & Mapping Using xboxdrvĬonvert RetroPie SD Card Image to NOOBS Image Install Virtual Gamepad (Must Be Run As Root!) I want it to succeed on all platforms.Validating, Rebuilding, and Filtering Arcade ROMs It's important they figure this out imho or the console launch is gonna be a bust, and I don't want that to happen. Probably the devs would welcome complete suggestions for alternate controller configurations. On Windows UWP, XBoxOne and Nintendo Switch targets, gamepads are fully supported, but remapping of controller constants is not permitted.If "remapping of controller constants is not permitted" means what it sounds like - I could be and am often wrong - it's maybe trying to explain you can't remap individual buttons within the GMS2 engine what you *can* do is create multiple sets of controller configurations to try to accommodate different player preferences, including maybe left handed players, and players who'd prefer to use a trigger button to fire.īut it's easier said than done. Remapping of controller constants is not permitted. On PS4, if you want to use the touch pad tracking you need to use the device_mouse_* buttons. Yoyo Games' Game Maker Studio 2 Gamepad Inputs Documentation If it's possible to move one of those functions to another button, or press-vertical function, that might be good too :) My other observation is that putting so much functionality on the right twin-stick "press down vertical axis" function had me frequently, mistakenly dropping map placement markers instead of switching off 'free aiming' and vice versa. Imho this one change would make controller - which with free look off to me is at least now close to how it feels in other twin sticks like Helldivers and the like - play more fun. This might require reworking other buttons to accommodate that. So my suggestion would be to try to figure out at least one "alternate button layout" where the right TRIGGER button lets us use fire primary weapon. It's confusing imho, and using the Trigger button for item activation instead of firing my main weapon feels off - it's like I'm 'fighting' against my memories of how triggers are used in other game. In my brief testing, it just feels confusing/wrong to be using the right *shoulder* button as both firing button and as reload button. It feels natural, whether the game lets you "hold the trigger" to spready an auto-weapon or 'tap tap tap' to fire pistols and semi-automatics. Here's my attempt to be constructive - the main issue is *most* overhead twin-stick shooters use a controller's right TRIGGER button for shooting.

Early in the day, Plant (Tampa, Fla.) 2023 defensive back Jaden Davis adjusted nicely on a 50-50 ball and came down with an interception against Sumner.Dickens is an athletic safety with great anticipation and vision and Brown made some acrobatic plays in the championship game. The Wildwood (Fla.) combo of 2023 S Jamari Dickens and 2025 WR/CB Vernell Brown III were fun to watch.Good ball over the deep middle and can fit the ball through tight windows in the red zone. East Lake got to the 7-on-7 semifinals…the more we got to sit and watch 2023 quarterback Jake Bechtel, more we found to like.USF is involved in his recruitment and he plans to take a visit down the line. Takes good angles to the ball and gets downhill quick. When Moore Haven played Seminole (Sanford, Fla.) in the quarterfinals, it took multiple series for the Seminoles to even throw his way. Locks down his area well and can play both the free and strong sides. In 7-on-7 work, we watched Moore Haven (Fla.) 2023 safety Kenari Wilcher for a few series.Appears that he’ll play both ways for East Lake next season, Byrne flipped over to the defensive side of the ball and showed ability to get through the line with good swim and rip maneuvers, then showed off some lower-body strength with a bull rush that was the only rep McMillian lost. Was picked out by a USF support staff member to participate in a best-on-best and he won the rep. Really strong lower-body that helped keep his top half level. Became a big fan of East Lake (Tarpon Springs, Fla.) 2024 offensive lineman Aiden Byrne.Jenkins has an offer from Toledo and his coaches tell 247Sports he’s also pulled in one from Florida Atlantic. Eventually was moved to the inside and showed some good burst moving to his right from the defensive tackle position.

Listed by Zephyrhills at 330 pounds, told 247Sports he was at 350 on Thursday. Good base, surprisingly good footwork for guy of his size. Doesn’t have any interest nor verbal offers, but could be a quick riser. Lined up at center and guard and won all but one rep that we saw (against another standout who we’ll touch on in a second). Starting with linemen standouts… Zephyrhills (Fla.) interior offensive lineman Damon McMillian had a good day.We’ll start our camp coverage off with a look at some standouts and notable performers from Thursday’s camp/tournament. Indoor practice facility construction on campus saw camp be pushed to the fields of the Hillsborough County Tournament Sportsplex on the outskirts of Tampa and went for just over 90 minutes, while the first of two Sling and Shoot 7-on-7 tournaments went until the mid-afternoon. Offensive line and defensive line got underway around 10 a.m. TAMPA - Amid a two-hour rain and lightning delay, USF football was able to host their first prospect camp and 7-on-7 tournament of the summer camp season on Thursday.

Please don’t spam likes on everything (liking spree) as it messes up the notifications and is tough to track things, this goes for any personal/non-rp blogs as well (as you be blocked for spamming the notifs). Anything that is on the mind feel free to send it in and I’ll do my best to rustle up an answer/reply for it. into the inbox, even ask OOC stuff as well too anything is fine when wondering on stuff. Non-mutuals are welcome to plop any starters, memes, etc. As long as there’s something for the other person to bounce a reply off it’s alright. Though you don’t have to match the length of what I write so don’t worry about that. Tend to write in one para, multi para and novella. If wishing to send memes in you can look through the #memes tag here so you can pick out what ones you wish to send in. I’m always accepting meme asks/prompts at anytime too, just make sure to say what meme the ask is from so I can get what you mean. But you’re welcome to send in asks if you wish so don’t feel discouraged on this. OC’s are fine if you want to interact with but will I be little selective though, so no worries on this and feel free to send your OC if you like to poke at my muse and see where it goes from there. Please make sure to have the link to were it’s coming from as well, as well in making sure to use the when tagging so I can get a notice of it so I don’t lose the thread. You’re welcome to continue things from an ask if you wish to, you also can make it into a separate post as well if that works out fine for you. Also can make a separate post for an open starter even if got started just make sure to do a separate post for it ‘please please’ that way no one gets thrown off on who is replying next. Open starters that have been not touched are a free to grab if you wish to roll forward with the starter, can ask/IM for one if there’s a idea in mind for anything. Don’t be afraid to throw ideas in and also open to starters that you like to send in the inbox as well. Open Multiverse ideas, Crossovers, AUs, etc. Though I’m a little flexible so just ask or IM me if there’s an idea to be had, another note is that I’m not very good at writing out battle sequences sorry about that. Fluff scenes are a bit of my strong point, but I welcome to do crack to serious rps as well though I’m a bit rusty at the serious part. I’m a bit iffy on toxic relationships and rather not go into them, sorry about that. If I’m missing one just give me a soft poke for a reminder or even give a link too, in case I missed the notice I’m not a mind reader okay? Thank you. Please don’t take it personally that I can’t get to the reply right away since, I either probably lose steam of muse to answer or that notifs are a putz and didn’t show it. I tend to bounce around when getting replies a bit, please be patient when I come up with the reply to your thread. Other than that I’m pretty much chill on answering things, OOC stuff is welcome as well if there’s any questions on anything or just liking to ask my muse something as well. Semi selective but I do give things a look over when looking through pages. Normally nixing the cape for the plain coat, his other attire is the same color as well.-Mostly based on my own headcanons and canon divergent as well from own interpretation. Haou dresses in dark clothing, usually seen sporting a black and gold trimmed coat and sometimes if wanted, a long, blood red cape connected by purple baubles across his chest. He takes pride in his appearance, and stature, never getting his hands dirty with anything, and thinking himself superior to others. The former ruler of Dark World uses Evil Heroes (a variant to Juudai’s Elemental Heroes) as well as dark cards like Super Polymerization, Dark Calling, and Dark Fusion. Malicious and highly uncaring for anyone besides himself, Haou takes great pride in his accomplishment in conquering Dark World. He sees Dueling as a way to dominate over people and is a bit of a loner. Haou is pretty much the opposite of Juudai - cold, calm, and collected. The darker, more harsh half of Yuuki Juudai’s soul.

The radioactive isotopes Ar/sup 39/ and tritium are measured in a number of Fe and stone meteorites. Quantitative data on radioactive concentration are presented. In the other 4 old siderites, with a limit of detection of about 10 gammas/min/kg, no gamma-ray activity in the energy range 0.2 to 2 Mev was detectable. In Aroos, measured 120 days after fall, Mn/sup 54/ was the predominant radioactivity Co/sup 60/ was the only radioactivity measured in the 4 samples of Siknote-Alin. Of the 6 siderites studied, only Aroos and more » Siknote-Alin showed detectable gamma radioactivity. Furthermore, thorium was detected and measured in 5 of the 9 achondrites. More unusual gamma emitters measured were 291-day Mn/ sup 54/, 2.6-year Na/sup 22/, and probably a mixture of Sc/sup 46/ and Co/sup 56+58/ (half lives approximately 80 days) these nuclides were detected in relatively recent falls (the youngest, the Harleton, Texas, chondrite, was measured 21 days after fall). Potassium and Al were the predominant radioactivities measured. The gamma spectra of 32 samples of 25 chondrites, 4 carbonaceous chondrites, and 9 achondrites were investigated using a large NaI (Tl) scintillation spectrometer. Investigation of the nearby sequence of volcanic rocks has been undertaken as an initial step in an effort to obtain definitive age data on the environment of the uranium occurrence. Metamorphosed Todilto limestone (Jurassic), found in the Section 33 mine beneath the lava on the mesa, contains uranium which has been dated on a single unconfirmed determination at 78 plus or minus 5 million years by Miller and Kulp. The porosity and high water content of the perlite, which give it the commercially valuable property of expanding when heated, are believed to have resulted from magmatic or hydrothermal hydration. Thus, preliminary observations suggest thnt meteoric water, which would be expected to introduce air argon, is not responsible for the hydration of the perlite. The perlite, a porous, hydrous glass, contains no more air argon than the massive vitreous obsidian. These are considered doubtful because of more » the low potassium content. Two determinations made on the plagioclase give 4 and 9 million years. Plagioclase from an andesitic plug which Pierces the mesa contains only 0.43% potassium. Perlite now being mined in an open pit along the northeast edge of the mesa corresponds with the obsidian in age. Obsidian masses along the north side of the mesa are dated at3.3 plus or minus 0.5 million years. Mex., yield age determinations which date one of the several recognized periods of volcanic activity. Six potassium-bearing specimens from Grants Mesa, a youthful volcanic complex just north of Grants, N. The lead-207 excess in the meteorite is 2.2 x 10 -9/ which would require 10/sup 10/ years for this excess to result from 1.5 x 10 -13 g/g of uranium-235. The experimental method used is described. The assumption was that both contain lead isotopes of the same isotopic composition when the bodies were formed. Thus, the uranium and lead contents of the meteorite are inconsistent with the common assumption made in determining lead ages for earth and meteorites. This amount is more than a factor of one hundred too small to account for the excess lead-207 in the Siknote- Alin meteorite in 5 x 100 more » years. Results showed less than 1.4 x 10 -14 g/g of uranium-235, corresponding to less than 2 x 10 -11 g/g of normal uranium. To test the assumption that the excess of lead-206 is due to the radioactive decay of the isotope uranium-238, of lead-207 to that of uranium-235, and of lead-208 to that of thorium-232, a search was made for uranium-235 in the Siknote-Alin meteorite, which is a meteorite that clearly has a lead-207 excess. |
