hi doggo! i keep wondering, as technology develops, would typewriter heads be eventually replaced with laptops, and would landline/cell phone heads be replaced with smartphones?

I could see it potentially happening one day, but no time soon. There already are laptop + smartphone heads of course (the demo title screen shows someone with a laptop head!), but the irony is that most people already have smartphones and laptops, so they're not really 100% necessary.

There's a lot of complex reasons why rotary phone + typewriter heads never died out, but a core reason why they never ended up being replaced by a similar, but more useful device (say a TV head or something with a screen) is that humans are beings of habit and that most people won't get their head changed unless it's super important to some part of their character. Phones and typewriters are the default given at birth, after all, because it's always been that way.

You could argue that the phone heads aren't really useful for the same reasons smartphone/laptop heads wouldn't be either, for much the same reason (the final DT route has a throwaway line from Karen where she brings up her smartphone) but given that inorganic heads are no longer the default (by Crown's design, of course), people tend to go for the default... unless they have a reason to change.

Lots of people do, of course, but for the average person, it's an expensive procedure to get done to you, and very difficult to perform on oneself. This is why you could view the head as more of a display of complete identity than a completely 1:1 replacement for gender. Most people with atypical heads in Dialtown have their entire lives structured around their head in some way.

Practically, vacuum tube + landline technology has the obvious advantage of being far cheaper to maintain/repair. This is the main second reason why modern tech heads haven't really caught on.

When I worked in antiques, I spent a lot of time with an old repairman who specialized in vacuum tube TV/radio repairs and he told me how circuit-boards basically annihilated his old job. Back then, you could be a repairman as a trade and actually change out individual parts when something went bad. As long as you understood how a TV or radio worked, you could repair any device by isolating the part that wasn't working and then swap it out. Nowadays, tech is made to be used for a few years and then discarded outright + replaced.

Gabby mentions in her store that poorer folk have to opt for doing self repair sometimes, in the same way poorer folks in OUR world might have to cut their own hair or god forbid, pull out their own teeth, if they go rotten. So, head-type (to a large extent) can be tied to class too, since a newer device (if it went faulty) would be a nightmare to repair, and it WOULD need to be repaired eventually, as laptops + phones tend to slow down somewhat in only a few years of operation and even deteriorate to the point of being obsolete in less than a decade! Not ideal for the thing housing your brain, no?

Hope this helps!!!

4K UHD Review: The Guyver

Following in the wildly successful footsteps of Batman and Teenage Mutant Ninja Turtles, The Guyver takes a (relatively) grounded approach to its outlandish source material — in this case, a Japanese manga series — without divorcing itself from its comic book roots. Produced by Brian Yuzna (Re-Animator, Society), the 1991 film is directed by special effects wizards Screaming Mad George (Society, A Nightmare on Elm Street 4: The Dream Master) and Steve Wang (Predator, The Monster Squad).

As the Star Wars-esque expository opening crawl explains, mankind was created by aliens as an organic weapon. The evil Chronos corporation is further developing a technology that allows humans to change into "super monster soldiers" known as Zoanoids for world domination. The only viable defense against them is The Unit, a piece of bio-booster alien armor that increases a human's natural powers a hundredfold, turning them into The Guyver.

Mark Hamill's top billing may lead you to believe that he's the titular hero, but he instead plays a supporting role as a CIA agent investigating Chronos. The real lead is Jack Armstrong (Student Bodies) as Sean Barker, an amateur martial artist who's the only person that can activate The Unit. When his girlfriend (Vivian Wu, Teenage Mutant Ninja Turtles III) is endangered, Sean utilizes his newfound powers to take down Chronos and the Zoanoids.

Armstrong is a bland lead, but it's not entirely his fault. In addition to a mustachioed Hamill channeling Colombo, he has to compete with several scene-stealing character actors. Re-Animator's David Gale chews the scenery as the malevolent head of Chronos, briefly reuniting with Jeffrey Combs as the company's scientist, Dr. East (get it?). Michael Berryman (The Hills Have Eyes) plays Gale's right-hand Zoanoid with Jimmie Walker (Good Times) as his rapping goon. Linnea Quigley (The Return of the Living Dead) cameos as a scream queen.

But the real stars of the show are the creatures, the designs of which showcase boundless creativity. The Guyver looks like Ultraman by way of Clive Barker, and each Zoanoid adopts a different animal's traits. While a number of other artists were employed to pull off the myriad of monsters, George and Wang's fingerprints are all over the effects, imbuing the alien superhero movie with some disturbing body-horror.

Jon Purdy's script deviates significantly from source material not only in terms of story but also tone. While some of the manga's dark atmosphere and violence remain intact, it's undercut by goofy humor in an attempt to appeal to a younger demographic. Fans of Yoshiki Takaya's original creation were no doubt disappointed (Wang attempted a bit of a course correction with his 1994 sequel, Guyver: Dark Hero), but the tonal confusion is actually charming.

Originally cut down to a PG-13 rating in the US, The Guyver has been newly restored in 4K from the original, R-rated 35mm camera negative with DTS-HD Master Audio 5.1 and 2.0 options for Unearthed Films' 4K UHD + Blu-ray release. Far removed from the days of Jaws and Alien in which the monster was largely hidden in shadows, George and Wang put their creations on full display — and even with a crystal-clear restoration, the in-camera effects shine.

Two new audio commentaries are included. The first is a lively one with George and Wang, moderated by Budget Biomorphs: The Making of The Guyver Films author Dom O’Brien. It's not the most informative track — the filmmakers admit to not having seen the film in over two decades — but they're enjoying themselves so much that it hardly matters. The second commentary features creature crew members "Evil" Ted Smith and Wyatt Weed, who delve into the nitty-gritty of the effects.

Yuzna and George each sit down for thorough new interviews. Yuzna reveals that he's been approached about a remake, but the rights are complicated, while George's infectious energy lasts the entire 56 (!) minutes. Creature suit camera test footage is included with commentary options from George and Wang or Smith and Weed, while outtakes and a gag reel feature George and Wang commentary.

Other extras include: alternate title sequences in English, German and Spanish; English, German, Spanish, and French trailers (all carrying the alternate title Mutronics); and extensive promotional and production galleries. The collector's edition also comes with the soundtrack CD composed by Matthew Morse (Silent Night, Deadly Night 5: The Toy Maker) and a booklet featuring liner notes by O’Brien and Morse.

The Guyver is available now on 4K UHD via Unearthed Films.

Spoilers for the entire Dawntrail MSQ!

Here's my post on the side characters.

Wuk Lamat's character isn't as bad to me as some people seem to think it is, but I think I did end up "liking" a lot of the side characters better.

This is actually also an opinion I have about Stormblood's story – eventhough I don't dislike Lyse, either, I take Gosetsu, Yugiri and the Azim Steppe cast above her (except Hien, I think he's really boring).

I just think a lot of the DT side cast is extremely effective in terms of screentime.

Koana's arc about being his honest self comes together when he gives up his position as a Dawnservant candidate to help Wuk, but the campfire scene with him and Thancred and Urianger is still one of my favourites in the expansion because it also ties together with their character arcs.

Aside from acting beyond his mask, he also gains nuance in terms of his absolute perspective regarding the value of technology.

It's a downright layered arc and I enjoy it very much.

I think people are really finger-waggy at Bakool Ja Ja's story because "it solves a bad system in 10 minutes", but I read it as more of a first step, especially in tandem with an aether current quest in the area, which had someone's whole world essentially crumble.

But I liked it for being an honest, earnest exchange between him and Wuk. He's the kind of minor villain trope that isn't the most graceful "redemption arc" because it is too close to a switch flip, but I also see him as pretty strongly in the side character bracket that doesn't really try to be a hyper-complex character.

He got a dark story, but to me it never felt like they wanted for you to cry super hard for him. Be shocked for sure, it is the first tone shift, but not really weeping your eyes out.

It reminds me a lot of the one-off Monster of the Week villain that might eventually become part of the main cast.

I ended up finding him super entertaining after he started supporting everyone in his own way, so I think he's actually not a misinformed redemption arc because he never goes back to being the same asshole, it's just not very gradual or "nuanced".

Next, I really liked Krile's journey.

The lalafell lore was neat.

But her getting to reunite with her parents was the highlight regarding her character and made me cry a bunch because it was both expected and unexpected; I was wondering where the story was going with her character the entire way through and it made so much sense to lean into her origin as an orphan.

On an emotional level, it was closure you would never expect.

I also really like the initial Echo cutscene with no dialog that first revealed her to be from another reflection. I love that kind of "show, don't tell" storytelling.

Otis is another favourite of mine. I love the contrast between his design and personality and just find his knightly behaviour super fun.

I know Zoraal Ja's child is another divisive character, but it's his relationship with Otis that sold his character to me. The campfire scene with them is super sweet. And doing the play with him was good closure. Not quite as tearful to me, but sweet nontheless.

Finally, there is Erenville. He was in a similar situation as Krile to me. The entire way through, I was wondering what they were going to do with him.

And it turns out, pain.

We learn about his mom early on and the entire way through Heritage Found and Solution 9, there is this feeling of unease when we meet her as "a robot".

In fact, I knew there is probably tragedy waiting in regards to her.

She's an absolutely wonderful character. Adore her teasing and "embarrassing mom" energy.

And Erenville is simply another example of how people face loss. And well, he simply couldn't face it.

Who could properly face everything he went through in the short time it is revealed in?

He went home the first time in years and was met with a completely different place he left with the person he probably cares about the most in the most morally horrendous situation you can think of.

His entire role in this expansion was suffering.

So when he finally honestly talked to her at the end, it was another really impactful scene to me.

I mentioned it in another post, but I know there is another pretty prominent complaint about some characters getting too little time in this expansion, but so many of them have just these really strong and meaningful scenes to me.

I'd rather take a character with 3 really meaningful scenes than 10 "simple" ones.

And I really, REALLY hope they don't walk back any of the deaths. Because this time around it really is intrinsic to making the story's point.

And these stories also left a lot of room for exploration for these characters.

Erenville has a newfound motivation for exploration I wholly believe.

Krile has an entire new civilisation to look into.

And I think Koana's interest and perspective on technology could still be explored.

And I actually think they really could do more with Bakool Ja Ja and Gulool Ja, too.

I'm a little worried about there not yet being setup for new true big picture 10-year stuff because all of this could be resolved in the patches, but I get the feeling that key might lead us to it.

I think a lot in the big picture perspective with this story and in that sense, I enjoy that DT left us with so many possible leads.

Maybe warp doors will have some story significance in deltarune, but I honestly like the idea of npcs helping you travel more, so here are my efforts to design them (thanks ribbit for inspo).

Ch1. Let's just calll her ms. Hazard. She's a pachisi game in light world (or other annoying luck-dice-based board game), and has a temper of middle shool kid who can't accept being defeated. She decided to help Fun Gang on a bet; she helps with transport for free, but if they fail to close dark fountain (die), all their belongings and inheritance is her. The actual transport device are animal pawns (last 3 she didn't sold to pay debts off). One of the heroes does teleporting animation, then screencut (to keep it short). After teleportation there is a small event of lucky or unlucky nature, mostly just narrator text.

Alt colors; casino, paschisi (aka.Mensch ärgere Dich nicht aka.chińczyk).Pawns with coresponding characters, pashisi board, pixelart.

Ch.2 Typin! Search bar! The personification of old people on the internet (nicer half). Seems like they stucked in seeing cyberworld like it was ~30 years ago. They uses old steam powered machines and are invertor and owner of teacup technology (correct me if I missed some fact in dt). They help you out of kindness and in travel cutscene (similiar to undertale) tell you anecdotes about ol'good times. Discussion is sometimes annoying, with them constantly mishearing and correcting everyone (did you mean..? google thingy).

Alt way of steering teapot, close up and first design I still like.

Kaoconi and my workspace after enambling all layers.

This evolved from mine old post^

FROSTTALE: Master Post

Frosttale is an au I made over two years ago now, and quite a few things have changed since i made the original concept on discord. At this point nearly every character has a finalized design and the story is complete, so i think its time i made it more mainstream!!!

Opening Cutscene:

Long ago, two races ruled over earth: humans and monsters

One day tragedy struck, a blizzard worse than any before it struck the human village and the humans believed the monsters to be the cause.

The humans fought the monsters, and sealed them into a cave, using magic to curse them with eternal cold

Many monsters suffered, and more died.

PRESENT DAY:

Legend has it that a furnace powered by seven human souls could stop the winter and break the ice barrier that seals them underground

MT. EVEREST, 202X

They say those who climb this mountain may never return.

(Thingy of chara falling into the underground blah blah blah game starts)

Ok so time for the changes!!!

this au centers around everything being cold, duh.

The most major change is that undyne is dead due to the extreme temperatures, and that drives nearly every other change in the au.

Alphys found her goop stuff after she died, scooped it up and saved it. Since then has been secretly using the royal scientist funds not for technological development but in an attempt to revive undyne.

One day, papyrus is walking around in waterfall, looking for undyne in a hope that somehow, he could find her (he doesn’t know that she’s dead, sans told him she’s just missing). Alphys sees him, and sees an opportunity (he has a similar body shape to undyne), she persuades him to come to the lab, then she knocks him out cold (see what I did there)

Papyrus wakes up a few hours later tied to a table and has a couple of wires and containers hooked up to him, most notably two labeled “remains” and “DT”

Due to the fact that he’s tied down papyrus is stuck there.

A few minutes later Alphys walks into the room and tells him that he will be ok, and tells him that if the procedure works, papyrus can be part of the royal guard, when papyrus asks what the procedure is, Alphys doesn’t answer.

Slowly, papyrus goes back to sleep, and the vials are all injected into him.

Once he wakes up again, he is now in a bed in a room that is similar to undynes, and is wearing a suit of armor also similar to undynes clothing.

Alphys walks in and tells papyrus that she cannot tell him where he is, and that he will stay here for the next few months.

Over the next few months papyrus is nurtured by Alphys, but notices something, Alphys is getting increasingly more stressed, and is now preforming daily checkups on him, and soon papyrus starts to notice something else.

Flesh.

Papyrus is growing flesh on his bones.

Flesh with scales.

And something else, papyrus feels much more determined and stronger in general, along with the sudden ability to be able to summon and throw spears as well as bones now.

However, the flesh doesn’t completely cover him, only parts of his limbs and face. He also loses vision in his left eye and needs an eyepatch, soon the changes stop.

Alphys realizes that her attempt at bringing undyne has failed and slowly realizes what she has put this innocent monster through. she leaves the lab and takes after her mentor, jumping into the core and killing herself.

Alphys has created Papyryne (name is a wip lmao).

Papyryne never found the key to leave the true lab, and has turned to be the caretaker of the other amalgamates, He has a lot of physical traits of undyne, while keeping most of the personality of papyrus, meaning he is now actually able to do the good deeds he once wanted to do. He makes the true lab look nicer, and treats the amalgamates like family

During all those shenanigans Sans has become very very lonely and quite depressed. He looks for papyrus everyday and can’t find him. He spends most of his time in his house or the judgement hall, or at least, he did.

Sans does end up meeting toriel, and in fact is at the door when you fight her, However sans never made his promise to not kill a human to toriel, as he feels that if there is an opportunity to melt the ice, he should take it.

After you leave the ruins, sans will have run away and back to his house. As you go through Snowdin, all of papyrus’ puzzles are completely frozen over and easily passable, and there are no monster encounters.

When you reach snowdin, no one is there either, they all either left or died, sans and papyrus, being skeletons, are the only ones who were able to survive the cold.

The river is completely frozen solid, and the ice cube machine is backed up with ice. When you reach the area where you would normally fight papyrus, sans will sneak up on you and start a battle.

The battle is different depending on weather you killed toriel or not. If you haven’t, sans is simply fighting you out of obligation, and the fight is very easy. After a few turns of acting and sparing, sans starts to cry a little. He doesn’t want to kill anyone, stating the underground has lost enough, and spares you. If you attack, the screen turns black and then you go back to the overworld. no sans in sight. If you do not attack, sans will not say anything, and go back to his house.

If you did kill toriel, the fight is a bit harder, but after a few turns, sans will run away regardless of what you do to him.

Entering waterfall, everything is frozen over, and again there is no life to be seen. There are two places of intrest, the old tem village (the new one will be mentioned later) where you can grab some nice items, and the village.

Upon entering the main area (the one with the save point and houses) you will encounter all three ghost characters, alphys was too obessed with reviving undyne to build mettaton, and undyne wasnt alive to need a training dummy (mad mew mew still happens post game btw).

Mad dummy forces the other two to attack you, napstablook being shy and mettaton being generally depressed (due to lack of body) dont really care too much, but fight you for their cousin anyways.

At the end of waterfall, they fight you one at a time (mirroring the multiple undyne fight segments). You can spare them by promising MTT and Mad Dummy that youll get them bodies (witch then becomes a pacifist quest), and letting blooky show you dapper blook.

Entering hotland youll notice everything is mostly ashen and gray, most of the lava having been turned to stone. You begin by passing through alphys's lab (nothing happens there... yet) and making your way to where MTT resort would have been, youll notice that as you enter hotland (now called "The Refuge" by most monsters) you can encounter monsters from anywhere in the previous areas.

Approaching the MTT resort location, youll instead find a bustling town called "New Snowdin", featuring Grillbys 2, a closed down nice cream stand, a royal guard sign up center, and... a massive cemetary.

In the cemetary youll find graves for muffet and lesser dog, as well as memorials for alphys, sans, and papyrus (the latter two being presumed dead by the public)

When attempting to enter the core, the door will be locked and have a sign saying "ROYAL GUARD ONLY", promting you to visit the sign up center.

You can sign up to the royal guard and enter the core, eventually getting on the elevator to the castle.

When you reach the top, youll be met by a hill, climbing on top of it youll find sans, he will explain that youre standing on top of the judgment hall, its been covered in snow

He says that for a long time, monsters have hated the king for his "wait out the humans" idea, and activley tried to revolt, promting the closing of the core to the public. He says that you are the final human needed, and sadly, you must die.

He then sends you off to asgore.

When you arrive, asgore brings you in for tea, sitting down with you in front of a large unpowered furnace with seven heart shaped slots, and explaining youre the first person willing to do so in quite some time.

He then escorts you to the barrier, and the fight begins. During the fight, your hp will drain very slowly due to the proximity of the barrier, being that it is what emmits the cold.

At the end, he reaches his final bit of hp, and then does something drastic.

You may have noticed a lack of flowey while reading this and thats because, well, he doesnt exist. flowers dont grow in these temperatures, and even if they could, alphys wouldnt have made him.

Asgore turns his back, and swings his trident, destroying the containers of souls, destroying them.

A second phase begins, he is now much powerful and has much more health, but eventually soul segments similar to those omega flowey has occur, and you can eventually defeat him.

You are then given the option to kill or spare him, if you kill, you recive the six souls and can break the barrier, if you spare, he takes you in as his own, and the game ends with you going to sleep in his castle.

This means that yes, there is no true pacifist run (but there is something similar...)

(Almost) PACIFIST EXCLUSIVE EVENTS:

If you have spared everyone, the elevator to the hill will collapse, bringing you to the true lab, where you can meet papyryne, he will treat you with kindness... at first.

He eagarly shows you around the lab, introducing you the amalgamates who he has lovingly named Puppy, Birdy, Snowy, Goopy, and Whispy.

However, as he shows you around youll begin to notice times where the font he is speaking in changes, and he becomes more agressive.

You can see the following entries on the walls:

Entry 1:

I found what I believe to be undynes remains today, something’s off though, it isn’t dust… it’s goop

Entry 2:

I’ve stored her remains down here, I plan to begin doing tests on it, seeing how she could have possibly gained DETERMINATION

Entry 3:

The DT extractor broke today, it will be a while untill it is fixed

Entry 4:

The memory heads keep looking around my shelf, spouting nonsense like “still there” or “don’t forget”

Entry 5:

The DT extractor is up and running again, I’m preforming some diagnostics, then tests begin tomorrow

Entry 6:

This is impossible

Entry 7:

I’ve made a discovery, in undynes remains, although there is only a fragment… her SOUL… is still there.

Entry 8:

The tests have been stopped, I’m attempting to recover some old files about the amalgamates

Entry 9:

Just as I thought, the records show that monster souls, when in their weakened state, can fuze, the most dominant soul taking the consciousness

Entry 10:

I took a small portion on undynes remains today and gave it to one of the amalgamates in their food, so far, nothing has happened

Entry 11:

It’s no problem, I simply need a bigger sample size, and perhaps a more stable monster with a complete soul, unlike the amalgamates

Entry 12:

I found a shyren today, I’ve lured it here and and captured it, I will be preforming the same experiment I did with the amalgamate

Entry 13:

…

Nothing is happening

Entry 14:

The shyren lost Vision in one eye today, though I am not sure if this is related to the experiment

Entry 15:

The shyren has been knocked out for 3 days now, I’ve hidden her body in the bathroom

Entry 16: I beleive I have found a new candidate for an experiment, this next experiment could be very very interesting.

As you are about to leave with him, freeing him from the lab, undyne takes over and he fights you. the fight is difficult by interchanging blue and green soul mechanics, the final attack using a combination of both.

You are forced to spare, as you cant damage him, and his fit of rage will end, he then will leave the lab with you and youll fast travel back to snowdin, reuniting him with sans.

You can then go back to the elevator and everything else will play out the same, with some additional sans dialouge at the end.

GENO EXCLUSIVE EVENTS:

You have to do like. a shit ton of grinding in hotland. You also have to do the ghost quests so you can kill them.

You reach level 14 and thats the highest you can get, you then take the elevator.

Once you reach the hill, you meet sans. He doesnt say anything, and a fight begins.

"it was a nice day today"

"can you see the snow sparkling in the light?"

"..."

"of course not"

"no one like you would stop to appreciate that"

"it was already bad down here, why did you have to make it worse"

"..."

"not much of a talker..?"

"me neither"

"but..."

"heres the thing"

"you see... king asgore needs one more soul"

"and youve got a nice one ripe for the taking"

"so... heres what im going to do"

"i am going to fight you"

"and i wont stop..."

"...UNTIL HELL FREEZES OVER"

then you fight, and at the end a similar cutscene to the one in UT will play, exept he doesnt ask papyrus if he wants anything.

you then go to asgore, and everything will play out as normal, exept you arent allowed to spare him.

EPILOUGE:

Holy fuck, that took so long to write. pleasepleaseplease if you have any questions feel free to ask, and i dont usually ask but if you liked it please reblog, i spent a lot of time on this.

ill be posting designs soon, and fanart would be much appreciated!!

Configuration design method of mega constellation for low earth orbit observation

Satellite constellation has been applied in communication, reconnaissance, navigation, and other space missions, such as GPS, Glonass, Beidou, Starlink, etc. With the rapid development of Low Earth Orbit (LEO) constellations, mega constellation will inevitably become an important means of Earth observation and a key point in the development of future satellite technology. The configuration optimization design of LEO observation mega constellation in complex space environment is a nonlinear problem that is difficult to solve analytically. During the development, constellation design principles have shifted from the uniform coverage requirement to application requirements. However, previous method cannot provide solutions to constellation configuration optimal design based on high-precision orbital propagation. In a research article recently published in Space: Science & Technology, scholars from Harbin Engineering University, China Academy of Space Technology, and Stevens Institute of Technology together proposed a configuration design method of LEO mega constellation based on basic and accompanying satellites orbit design, considering satellite imaging width, formation flying of subgroup satellites, and global uniform coverage by payloads.

First, satellites in the mega constellation are categorized and the constellation design based on different satellite division is proposed. Satellites in the mega constellation are divided into 2 types, namely, the basic satellites and the accompanying satellites. All basic satellites that are surrounded by accompanying satellites are evenly distributed globally, and they have the same subsatellite trajectory. A basic satellite and its accompanying satellites are defined as a satellite group. The constellation is composed of many satellite groups, as shown in Fig. 1.

As for basic satellites, the semimajor axis a of regression orbit can be numerically solved considering (1) that regression orbit requires a satellite flies R times around Earth in D days and (2) that the influence of J2 perturbation force of an orbit satisfying e = 0 and M = f is zero (i.e. dΩ/dt = 0, dω/dt = 0, dM/dt = 0). Assuming that the ground coverage width of a satellite group is d, the number of basic orbital plane is Nt = ceiling(2πRe/d) where ceiling(⋅) is the round up function. Assuming that the maximum response time to complete Earth observation mission required by the user is mt and the orbital plane is evenly divided according to the orbital period T, the number of basic satellites in each orbital plane is Nn = ceiling(T/mt). Based on above analysis, input the i, e, and ω of the constellation and Q = R/D, then the basic satellites constellation is designed.

As for accompanying satellites, they have the semimajor axis with basic satellites. According to the Clohessy-Wiltshire equation, the relative motion trajectory between the basic satellites and the accompanying satellites is an ellipse. Then, considering that the position vectors at the initial time and T/2 relative to the basic satellite is oppositive, the orbital elements of the first accompanying satellites can be solved. Assuming that the imaging width of a single satellite is sd, the number of accompanying satellites in a satellite group is Na = ceiling(d/sd - 1). Divide the trajectory of the first accompanying satellite relative to basic satellite orbital coordinate system in chronological order, extract the position vectors of all equal points under the orbital system, and use these as the position vectors of other accompanying satellites under the basic satellite orbital system at initial time.

Combining the basic and accompanying satellites’ orbits, the configuration of mega constellation is obtained.

Then, the orbit parameters of satellite and its companions are set as initial values, and the precise orbits under the High Precision Orbit Propagator model are solved in the neighborhood by using the Nondominated Sort Particle Swarm Optimization algorithm. Transform the orbital elements of any basic satellite into position and velocity information, which is recorded as {pxpq, pypq, pzpq, vxpq, vypq, vzpq}. Add an increment to build their neighborhood, which can be expressed to {Δpxpq, Δpypq, Δpzpq, Δvxpq, Δvypq, Δvzpq}. The optimization variable of accompanying satellite orbit is the position and velocity increment of all basic satellites. The optimization objective f1 for the basic satellite configuration is to minimize the absolute difference between the ascending and descending nodes of any basic satellite bspq in cycle i, and the ascending and descending nodes of bs1q as much as possible. The optimization objective f2 of the accompanying satellite is to keep the relative position as close as possible under the basic satellite orbit system at multiple subsequent motion periods. Optimization iteration process involves continuously approaching the Pareto front. In practice, find all nondominant solutions of the initial individual as the optimal solution set. Calculate 2 optimization objectives of everyone in sequence, and use the nearest global nondominated individual and own historical nondominated individual as learning objects. Update individual optimization variables and variable increments based on population information, individual experience, and self-inertia, as shown in Fig. 10. Then calculate the f1 and f2 of newly generated individuals again, and regenerate the global Pareto front and individual historical Pareto front. After a fixed number of cycles or objective function is less than the threshold, the iteration ends and the global Pareto front can be obtained. At this point, the final constellation configuration can be selected based on user preferences or linear superposition of f1 and f2.

Finally, the correctness of the configuration design method is verified by numerical simulation. In the simulation, set the constellation orbital inclination as 66°, eccentricity as 0, argument of perigee as 0, simulation time as 1 d, set regression coefficient Q = 15, initial ascending node as 0, initial MA as 0, imaging width of a satellite group as 1500 km, imaging width of single satellite as 140 km, and maximum working time of single satellite to orbit single circle as 35 min. During the optimization, it can be observed that the approximation speed of the Pareto front in the first 100 generations is extremely fast. As the number of iteration increases, the variation of the Pareto front gradually decreases and eventually becomes stable. In the final generation of nondominated solutions, we select the individual of f1 = 1.981 and f2 = 9516.482 as the final solution, and the constellation configuration is shown in Fig. 15. The constellation has a total of 891 satellites, of which 81 basic satellites are evenly distributed, with 10 accompanying satellites evenly distributed around each basic satellite. A total of 810 accompanying satellites can achieve collaborative observation of any position outside the polar region within 35 min.

Blog Post #4

In what ways does being critical of security with technology protect tech consumers from being exploited?

In the speaking event for this week, we discussed media literacy and, more importantly, the concept of surveillance and how we can limit the data that large technology companies get from our usage. Regarding exploitation, we know that our data is often used to sell back things to us as consumers! Our data is sold to tell us what ads we like, to show what ideals we have, and, therefore, how we can buy things. I question how being critical of where our data goes helps us from getting exploited both as consumers and as unknown producers of funding for these websites.

How are “Cyberspace”, or online digital spaces, now even more so, designed to make it hard to contextualize race online?

Kolko et al. (2000) discuss the implications of cyberspace on race and identity portrait and how online space tends to promote ideological depictions of the cyborg. This non-gendered or raced entity is portrayed as a member of online communities. The article describes the importance of understanding race in cyberspaces and why the disconnection of race causes issues in grander topics discussing race in society. However, as time has continued, many platforms continue to disconnect race ideologies within their speech. One example I can think of is Twitter, and how it is often ungendered, unraced, and unnamed profiles that continue to describe and comment on race relations from the “real world” while not acknowledging the implications of race and treatment of others online in a deeper, macro-level way. Topics about race and gender are romanticized rather than seen in a social light; it is interesting to see how those times have changed.

In what ways is does digital disembodiment within the video game encourage online discrimination?

In the TED talk 5 Types of Racism (Tedx Talks, 2011). , We see that Rampage Jackson gets actively discriminated against while playing Halo as a teen. We know that digital media tend to have a want to become disembodied with race and racism as a space. Videogame spaces are often seen where people can say and do whatever they want without concern or remorse for the players at the other end. Disembodiment, then, encourages racist and prejudicial behavior, as there is a lack of humanity and actual consequences associated with prejudice.

How are racial stereotypes in video games used to spread disinformation within video games?

Also, from the TED talk (TEDx Talks, 2011), we learn that identity tourism is utilized to take characters and make them act out stereotypes. The video discusses how this action can act as minstrelsy, a parody or imitation of a specific group or stereotype. However, can individuals use these identity tourism attitudes to continue perpetuating negative stereotypes and information genuinely? In what ways can racial stereotypes in video games be used for genuine social information gathering? I can argue that pretending and acting out as another identity to make fun of or play on stereotypes may spread misinformation about those groups, acting as a form of disinformation technique.

so here's a little rant & i wanna gauge your opinion on the matter. i just finished watching civil war (it's finally available digitally) and... it doesn't look like ass. not that i expected it to but you know how everything looks overly HD right now and it's just awful? well it wasn't like that. and that got me wondering what's really happening with camera/lenses quality right now because i was beginning to think the move to everything looking overly crisp and awful was kinda forced by the way they make camera equipment/technology now, but there are many things that still look fine, not 80s-mid00s amazing, still a bit too HD for my taste, but fine. meanwhile there are things like good omens that look so bad it's legitimately triggering some kind of ocd for me and physically hurts my soul. like apart from lighting/director decisions it's just so damn sharp, it makes MS and DT look grotesque (even though they are objectively good looking, or at least on the nice side of normal looking, guys). do you have an opinion / some technical knowledge on the matter? why is this happening?????? if select movies can still get their cinematography looking nice then what's the deal with all these other productions being offensively ugly looking? i don't get itttttt. like obviously one assumption would be budget differences but you'd think then they would get older equipment that's not ultra HD shit. or is ultra HD shit cheaper. help me out here because i honestly can't watch most things made post-covid they are so terrible looking. iwtv is another example of something that looks too HD to me btw, just so you don't think my issue is like with bad direction (but rather image quality? idk how to put into words my hate of ultra HD in technical terms)

I had the same reaction when I watched challengers yesterday!

It’s film v. digital. I haven’t watched civil war but even to be untrained eye I could guess that challengers was shot on 35mm film, not digital. That’s why it has that beautiful warm grainy quality. I would say 95% of movies and tv shows are now shot digitally - it is much cheaper overall. No risk of the film being damaged or worrying about the literal cost of physical film you’re burning through. and in digital you can choose a lot of your setting when you’re shooting.

Now within digital, you have 2k and 4k (ultra high def) as you call it. And this is where we reach the limits of my technical knowledge because like…better call saul was mastered in 4k and it still looks fucking fantastic!! This is why I will still blame light design/directing because we have proof that 4k can look good. It’s just the way everyone else is color correcting/lighting the scenes that’s the problem

Blog Post #5 (Due 10/3)

How does the merit system in “Nosedive” parallel our perception of social media following?

In the “Nosedive” episode of Black Mirror, each person ranked everyone they interacted with, and one’s overall ranking determined how they were perceived and interacted with by others. This immediately reminded me of how social media status dictates our interpretations of one another. As few people would admit it, I know of many people who when looking at someone’s Instagram account for the first time, make judgments about them based on how many followers they have. Furthermore, when it comes to influencers, many companies only want to collaborate with those who have a certain amount of followers, leaving smaller social media creators to work extra hard to build their platforms. In “Nosedive,” each character’s rating offered benefits to those with particularly high ratings, such as reduced rent, access to certain buildings, and better overall social standing. This is an eerie, but realistic, example of how we let social media standing guide our interactions with people in the real world.

Why is language especially important when discussing social problems and feminism?

The language we use when discussing social issues is very important because it can make the difference in acknowledging or dismissing nuance in these issues. As we read two weeks ago, intersectionality is vital when discussing feminism to ensure that “women’s rights” include all women. As discussed in The Revenge of the Yellowfaced Cyborg Terminator, the authors argue that Haraway’s position as an established, respected white feminist grants her the privilege of an audience: people want to listen to her. However, if a woman of color made the same arguments, she’d likely have a much more difficult time gaining that same audience. When discussing social issues like sexism, it’s important to think critically about the language we’re using and how it may be interpreted to build stronger, more nuanced arguments.

How is voice-based racism more prevalent now than ever?

In her TedTalk, Dr. Lisa Nakamura explains voice-based racism in reference to the judgments we make about someone’s race based on their voice. She argues that with the rise of video games with live audio features (where you can play with friends and strangers), there’s also a rise in voice-based racism online. When we believe we know someone’s race simply from their voice, we open the door for stereotypes and prejudice to guide our interactions with that person. Furthermore, everyone is prejudiced, and these prejudices continue to exist online. I believe making judgments on someone’s voice online is relatively similar to making judgments about their appearance in real life, so voice-based racism is especially important to analyze and acknowledge when we are guilty of it.

What is ludo-Orientalism and how does it work?

→ In The Race card: From gaming technologies to model minorities, the author defines ludo-Orientalism as the way that the “design, marketing, and rhetoric of games shape how Asians as well as East-West relations are imagined,” as well as how Asian people are constantly depicted as “other.” It also refers to the way social constructions of race are perpetuated through games and disguised as “play.” This can be particularly harmful because when something is deemed fun, we assume it to be lighthearted, and we often even assume it to lack any real, societal effect. However, the portrayals of racial groups through video games are often disguised versions of stereotypes, that then get perpetuated for the sake of “a fun game.”
