Mallon thinks that in the few successful cases where the synthesized voice manages to capture the microemotions of the original, the result could tremendously help a person process grief. “Will the person be able to tell a sentence in a state of horror or excitement and laugh at the same time?” Mallon asks. The fact that it only takes a minute for Amazon to reconstruct a person’s voice does not reflect a lifetime of emotions, though. Your voice fingerprint is your genuine voice, with all of its unique characteristics (think: voice biometrics). They’re using data of thousands upon thousands or more people who speak English as the base kind of language model, and then adding your voice fingerprint to it, generating your synthetic voice within a few minutes,” Mallon explains. After Death, You Could Be Resurrected as a Chatbot.What Happens to Your Data When You Die?.Mallon is an app developer who’s worked on projects for Alexa’s voice services and is the founder of voiceOK, an app that preserves recorded stories read aloud by loved ones. Then, they’re going to adapt the base model accordingly,” Lee Mallon tells Popular Mechanics. “Amazon, in specific, is using a bank of audio they already have to build a base model. To create synthesized speech, you chain together pieces of recorded speech that are stored in a database. Robotic speech synthesizers have been around for a while, but they didn’t truly make their way into pop culture until the 1980s, when the theoretical physicist Stephen Hawking started using his. Prasad did not say exactly when this feature would roll out, and there weren’t further details on how it would work. Then, the boy’s “grandma” began to narrate the classic children’s novel. “Okay,” Alexa responded in its typical voice. “Alexa, can grandma finish reading me The Wizard of Oz?” A young boy asked a cute Echo speaker with big Panda eyes. Prasad used a short presentation to show the audience how the new speech-synthesizer technology could help us forge lasting memories of our deceased relatives. With just a one-minute audio sample, the technology could bring a loved one’s voice bounding through an Echo device’s speakers. In fact, the cloud-based digital assistant’s voice may ricochet off your kitchen walls in the voice of your deceased grandmother, spouse, best friend, or even Elvis Presley.Īt least, that’s what Rohit Prasad, Amazon’s senior vice president and head scientist for Alexa, announced at Amazon’s re:MARS conference, a global artificial intelligence (AI) event that Amazon founder and executive chair Jeff Bezos hosted over the summer. In the very near future, Amazon’s famed voice assistant, Alexa, may sound quite different from the dutiful (and impersonal) voice you’ve grown accustomed to since it rolled out in 2014. This vocal eternity comes with certain risks, though, from bank fraud to putting words in deceased influential figures’ mouths.It’s a feat of speech-synthesizing technology, which has been around for a while, but is now gaining favor with big companies.Amazon’s Alexa soon may be able to talk to you in custom voices-like the voice of your dead grandmother.

Your scoring will likely take a nosedive if you die, but the only consequence of dying otherwise is that your remaining lives is decreased by 1, and your bomb stock would be reset. Notably, when CAVE made Dodonpachi Saidaioujou they got rid of powerup items entirely, probably because keeping them was pointless by then. Most also either let you keep your powerups, or scatter all your lost powerups so you can collect them right when you respawn while you're invulnerable. Shepardus wrote:There are plenty of games with "lives" rather than "health," but don't make you lose any progress when you die.Can you name a few and describe exactly how they operate? Maybe if I see some examples I can understand what people mean.Īll of CAVE's shmups, with the exception of Progear's second loop, respawn you at the same place you died or at the edge of the screen without any rewinding. I'd wager that the terminology is the main source of disagreement here, and that if you ask people here whether they prefer having checkpoints and powering down on death or not, then most would prefer the more forgiving system, which is why a lot of the more modern games tend to be like that. That's why I made the distinction above about a "healthbar" allowing for different damage values, which would distinguish such a system from a discrete "lives" system. The only non-aesthetic difference between that and a healthbar with discrete segments is that your player character may visibly blow up and respawn in the corner the screen, which wouldn't make a whole lot of sense presented as a healthbar. You're right that if you respawn at the same place you died and don't lose any significant power then it's a "rose by another name" situation. enough that it makes the game harder and getting the power back is nontrivial). a checkpoint, and/or lose a significant amount of powerups (i.e. I'm taking "losing progress" to mean that you get sent back to a previous part of the level, i.e. To take Magical Chase as an example yet again, if you took the healthbar and replaced the heart icons with icons of Ripple's face, it's still a healthbar and still the same game. As I wrote in my last reply, if you're looking at a game where you can 'die' but you reappear in exactly the same spot with exactly the same gear in exactly the same state (no lost progress) to me that's just a healthbar but with a graphics swap so that the tick marks on the bar are replaced with a row of ship icons. I don't really get how you could have 'lives' that don't do something like this. For me, the concept of lives is basically synonymous with the concept of losing progress and dealing with grind- you have a limited number of tries to complete a section, and each try punishes you (to some degree) by making you start over from some previous position or making you lose your stuff or whatever. Maybe I'm not understanding what people consider or refer to under the word "progress" and what it means to lose it. Shepardus wrote:I feel like we have a difference in terminology hereProbably. There have to be at least a couple more out there somewhere. Magical Chase has several of the elements I like and other games have a few here and there so I know it's not impossible. Right now that means old arcade and console roms. I know full well that in asking for a 90's game (especially a 90's shmup) without this stuff I'm basically asking for a needle in a haystack, and that what I'm looking for is clearly the opposite of what everyone else likes anyway, it's just that I want something that will run on multiple platforms and I'm not willing to throw any money down yet given my odds. If it's what you're into then great I guess, but it might as well be liquid death for me. While other types of games slowly moved away from nintendohard, the shmup world seems to glorify it and any games that try to break away from it (ie healthbars, "Euroshmups", etc) tend to get heavily derided for one reason or another. My problem is not "I hate shmups" but rather "I hate nintendohard". Games that don't do that shit I enjoy quite a lot. Preference for one-hit-kills, bullet-hell, obsession with score and complex score chaining, etc. I do like the idea of shmups and the overall concept, I just don't like the circlejerk that the genre has turned into over the decades.

Threepio served as droid communication chief for the Resistance. Threepio helped retrieve Admiral Ackbar from the clutches of The First Order, but at a great cost. The Ewoks were ferocious allies on Endor and helped turn the tide against the Empire, all because they listened to C-3PO.Ĥ. Complete with sound effects, Threepio’s harrowing tale of Darth Vader, spaceships, AT-AT’s, and a city in the clouds turned the tribe’s sympathies toward the Rebellion. It took C-3PO’s shiny golden appearance and a little bit of help from Luke Skywalker to capture the Ewok’s attention, but it was Threepio’s recounting of the Galactic Civil War that finally gained the tribe’s loyalty.ĭon’t believe the fussy protocol droid when he insists that he isn’t good at telling stories. He convinced some very unlikely allies to join the Rebellion. “Curse my metal body! I wasn’t fast enough,” he wailed.ģ. If C-3PO hadn’t turned on the comlink at the last possible moment, what fate might have been in store for Chewbacca, Princess Leia, Han Solo, and Luke Skywalker? Luke probably never heard a sweeter sound than Threepio’s harried voice on the other end of the comlink.Ĭ-3PO’s reaction to their plight also revealed the connection he already felt to his new friends. The Death Star’s trash compactor was almost the abrupt end of the rebellion. Threepio and R2-D2 rescued the future heroes of the rebellion from the garbage masher just in the nick of time. Republic warships packed with troopers soon arrived on the planet, and they saluted an incredulous Threepio as they landed.Ģ. Then he contacted the clone troopers on a restricted frequency. Threepio distracted the battle droids (“I think that was rather clever,” he told himself proudly) and walked into the communications room without a single blaster bolt sizzling through the air. Then she sent the wary protocol droid on his own mission to send a distress signal to the Republic. But Padmé easily escaped from her cell and rescued Threepio from the battle droids. She fell into a trap by the Separatists and was held captive by her desperate friend in exchange for food for his people. With Jar Jar Binks and C-3PO at her side, Senator Amidala answered a plea for aid from an old family friend on Rodia. Threepio called in reinforcements to save Senator Padmé Amidala from the clutches of the Separatists.

That’s right, we’re talking about the indispensable C-3PO.Ĭ-3PO may not be a smooth-talking smuggler with a blaster at his hip or a lightsaber-wielding Jedi, but he can still save the day. But just because you’re not built for adventure, that doesn’t mean you can’t be a hero, as evidenced by everyone’s favorite protocol droid. Some beings, in fact, can only be described instead as a worrier. It's coarse and rough and irritating – and it gets everywhere.Not everyone in the galaxy is a warrior. The latter is the most insufferable, since George Lucas never had much of an ear for dialogue, as notoriously pointed out by Harrison Ford when he declared on set: “George, you can type this s***, but you sure as hell can’t say it.” Which leads us to one of the worst line readings in cinematic history, when Hayden Christensen’s Anakin laments: “I don't like sand. It’s a film driven by unnecessary desires: from the space politics, to Boba Fett’s backstory, to Padmé and Anakin’s romance. While Revenge of the Sith has some sense of completion and The Phantom Menace has some sense of wonder, all Attack of the Clones has is a CGI Yoda bopping about the screen like an unswattable fly while battling Christopher Lee’s Count Dooku. The prequel trilogy has lived on in infamy, but the true low point of this low point in the Star Wars franchise must be Attack of the Clones, the dry, crusted middle of the cinematic sandwich. It has really flavorful beef, which they also serve in their tacos de birria, but the cheese absolutely makes it. It’s larger than most street tacos and fried to the point that the cheese is like the burnt bits on a lasagna…aka the best part. The tortillas are served crispy and often have more stuff in it, like cheese, onion, etc. They serve Tijuana style tacos, which you’d think are like the best tacos in San Diego, but are quite different.

I’m happy to report back that Seattle is an incredible spot for street tacos. I revisited some of my tried and trues, plus tried some new ones known for serving authentic street tacos with meat, white onion, cilantro, salsa, and that’s it. So I set out on a research mission to try as many as humanly possibly in a two week time frame. This obsession started because I saw so many taco trucks and was overwhelmed why which ones to try. Serve with lime wedges, remaining CHEETOS ® and broth for dipping.I went on a mission to find the best street tacos in Seattle. Garnish with remaining onions and cilantro. Repeat with remaining tortillas, remaining beef mixture, remaining nacho cheese sauce, more diced white onion and more CHEETOS ®. Top with 2 or 3 tbsp beef, 1 tbsp + 1 tsp nacho cheese sauce, 2 tsp diced white onion and 1 tbsp CHEETOS ®. Cook for 2 to 3 minutes or until tortilla is crispy and cheese is starting to melt. Using metal spatula, flip tortillas and sprinkle each with 1/4 cup shredded cheese. In large cast-iron skillet set over medium heat, working in batches to avoid crowding, brush tortillas lightly with stewing broth and transfer to hot skillet cook for 2 to 3 minutes or until lightly toasted. In small bowl, lightly crush CHEETOS ® FLAMIN’ HOT ® Cheese Flavored Snacks. Discard remaining solids from Instant Pot. Using slotted spoon, transfer beef to clean large bowl and shred with 2 forks.

Yet, even when cells are fully adhering to one another, they can still display wavy cell walls. Similarly, when cell-cell adhesion is less prominent naturally, cells can also round up or exhibit irregular shapes, as in the leaf mesophyll and spongy parenchyma for instance. When cell-cell adhesion is artificially affected, cells can round up. This explains why most plant cells in fully adhesive tissues have a brick shape (e.g., hypocotyl cells). In tissues, cell shape is also constrained by the presence of adjacent cells, through packing and adhesion at the middle lamella. Typically, when they are still growing, larger cells are more susceptible to wall failure than smaller cells. Beyond the wall properties, the mechanical balance operating in plant cells also depends on cell shape. In fact, when cellulose deposition is impaired, cells also tend to become spherical, as in protoplasts. Cellulose microfibrils are classically thought to play a load-bearing role here, and their alignment supports the mechanical anisotropy of the wall. Typically, wall-less protoplasts are spherical. Because turgor pressure is in essence isotropic, any deviation from a spherical shape is determined by the mechanical anisotropy of the cell wall. An isolated plant cell is shaped by the balance between turgor pressure and cell wall resistance to turgor. Plant cell shapes depend on internal and external factors. Whether in kinematic analyses (e.g., ), in functional genetics (e.g., ), in cell biology (e.g., ), and in computational modeling (e.g., ), quantifying cell contours during growth is thus crucial to understand plant development as a whole. From a geometric perspective, this means that plant morphogenesis mainly depends on the cell growth rate and growth anisotropy. Because plant cells do not migrate, and usually do not go through apoptosis in young tissues, plant morphogenesis primarily relies on cell elongation and cell division. Cell shape is a primary variable in morphogenesis in all kingdoms, either as a building block for multicellular shape or because cell shape in turn biases the behavior of structural elements (e.g., cytoskeleton) or morphogens. |
