My programming career are making good progresses: Two wxWidgets programs dedicated for analytical methods.
It even contains a built-in calculator and a Xlsx basic library to read and write simple Excel 2007 files! 

And my fandoms are also going so far. Once I adhere the My Hero Academia fandom I create some stories based on Izuku Midoriya and apply some cross-overs on it. 

https://archiveofourown.org/users/NosferatuArucard1983/pseuds/NosferatuArucard1983

A villain Izuku with Yu-Gi-Oh Arc-V cross-over, where Izuku's quirk is a monster card like Zarc: Supreme Demon King Dragon Deku, capable to treat several quirks as Fusion/Synchro/Xyz Monsters and negate their effects. 

One long story where Izuku is a mixture of Geralt of Rivia (Witcher), Dark Schneider (Bastard!!), Guts (Berserk), Alucard (Hellsing) and Shiba Tatsuya (Mahouka Koukou no Rettousei), but it mainly the first two.
In reality is a vampire with magic, also called vryko-warlock  , and quirkless (since vampiric telekinesis had different natures) 

To resume the story so far:

Izuku is a natural born vampire, and he got first his vampiric telekinesis at age 10 (too early for a vampire!), and magic at 13. His mother Inko hire a private vampire magic teacher to learn his Black Magic and learn another ones once he got some Grimoires.
From his training, Izuku use the Witcher Signs at a first line of defense, before cast more advanced magic from Dark Schneider's Grimoire.

1. The slime incident ends with the villain killed, once Izuku casts the Venom spell:

Sasado! Sasado! Schrono! Chronos! Yoku-Sukou!
Burning from the depths of Hell! Unleash the Black Mist of Hellfire! May the Underworld Fire become my sword and punish the Enemy!
VENOM!

However another villains appears and also ended killed... Katsuki, who already knew that Izuku was a vampire, and only witness the weak telekinesis so far, never expected that he could be a mage!

2. The Entrance Exam was a piece of cake. Magic Spears simply destroy all robots, even Izuku was 100 meters from them. Witcher Signs also makes some points.
The 0-Point Robot was taken down by Dark Schneider's Megadeath: 

Deep Doomsday!
Spirits from the Air and Earth, I summon you to honour the ancient pact!
May the Earth and Sky explode to fulfil your duty on me!
MEGADEATH!

3. It also contains some character from One Punch Man, specially the Sound's Speed Sonic who appears when the mass media (like on anime) tried to rush inside, but on the story Sonic kills the journalists, and tried to kill several Yuuei students on the cafeteria. Many students form 1-A class also helps Izuku to contain the freak ninja.
Izuku here use (my original) spells inspired on Elemental Magic (like on Negima or Mahouka) to fight Sonic, but switch to Dark Schneider's since the threat was higher:

Enemy foolishness! Release the Revenge of Underworld! IMPELLITERI!
-----
Seek! Spirits of Lightning! Destroy! The Blood Fire of Death!... VOIVOD!
-----
Great Ancient King of Northern Ices, I pledge your forged Pact! May your enemies be annihilated by the Realm of Ice and Snow!... Extreme Zero Intense Froze Wave! BISCAYA!
-----
I summon the Fiery Power Blast from the Fallen Heroes! DAMNED!
-----
Oh... My Ancient Demon Servants, Guardians of Burning Marshes!... I honour your blood pact... Lend your Powers, and Reduce my Enemy to Nothingness! NAPALM DEATH!

However Sonic flees before Napalm Death could killed him.
Either way, many colleges from Yuuei ended frightened when Izuku display that magic spells, thinking that he has a monster with several quirks, where in reality don't have any, but already knew that he's a vampire.

4. Aizawa is also a vampire, and due to mixtures he got a human quirk, the same on canon, along vampiric magic. Aizawa don't like when Izuku casts Black Magic, specially the magic derived from Dark Schneider, and he still trying to Izuku use more the Geralt's Witcher Signs.

5. Instead the League of Villains, the Millennium Army from Hellsing cannon and the Twelve Wise Men of Europa from Bastard!! cannon are the main enemies. 
Some years before the main plot, the Millennium Army invade the North Korea a plant a puppet government in order to increase the Nazi vampires soldiers, and create an army of super-natural soldiers, along quirk soldiers under direct command of Anthrax (Bastard!!) and Major Montana Max (Hellsing). 

6. Like on canon, they make a first attack on USJ, but with a NKA (at first they don't notice, since the NKA/MA military unit insignias was under an undercover mission) battalion, along some Lestze Batailon vampire soldiers. Izuku, under extreme pressure, cast an Halloween spell to blast either the enemy or the USJ site. Since it was an highly destructive spell, Izuku endures a slow recovery of his magic powers that takes an entire month!

Kayzard! Halsard! Kiske! Kay! Hansen! Grosskopf! Sielck!
Cast all wise men of Hades and Gather the Seven Circle's Keys of Hell!
Open the Gates of Tartarus and Unleash total destruction!
HALLOWEEN!

7. The Yuuei's Sport's Festival was somehow easy for Izuku. Katsuki and Todoroki gives him some challenges, but ended defeated by the Gilbert and Tesla magic spells that combines Lightning Elemental and Black Magic materials. The match against Shinso ended with thier Brainwashed quirk blocked by the Witcher Sign Yrden (a magic trap), and reversed by Axii (also brainwashing magic), just to be blasted away by the Damned spell.
Sonic and Metal Knight (One Punch Man), who are mercenaries here, also appears to create havoc, while the Japanese Army  also watches Izuku's trials to convince him to assign the First Hero Internship on the SDF.
Since the SDF incited Izuku to kill Sonic and Metal Knight, first Izuku casts a quirk/magic cursing spell, to serve as a warning:

Ki… Obos… Plataro... Come forth, my Demon King, flying on Bat Wings!... May your Ancient Will seal this Cursed Pact!...
ACCUSED!

Instead the Accused transform the victims into toads, like on Bastard!! canon, it opens a cursed gate from Hell that makes the victims spontaneously combust, and been eaten by demons, if they disobey the curse written with runes on victim's bodies. 

And since the villains resume their offensive against Izuku, he decide to summon a dragon in order to destroy them quickly:

Grand force of the Pentacle, darkness and light… The moon is full!
I'm calling the Ancient Spirit of the Dragon King who died on War!
I'm cast the Great Power of General DeMaio, honouring the Spirits of Sky, Earth and Mankind!
Grant to me the Holy Strength of the Sacred Three-Headed Golden Dragon!
MAN-O'WAR!
--------
MAN-O'WAR... I command you to destroy the evil… By Honouring The Three Great Generals of Blazing Extermination!… The Three Great Shinsengumi Captains of Bakumatsu!... Attack!... Tennen Rishin-ryuu!...  Aku Soku Zan!

The second part was the order given from Izuku to attack the villains, ended burned alive.
Izuku won the Festival, but his reputation was a vryko-warlock gives to the public a sense of terror, but the offer from SDF was too strong to be avoided, or Izuku could face several downgrades.

8. However a civilian vampire request Izuku to rescue his brother vampire from villains, which the ringleaders was a hybrid magic/quirk users, gives an opportunity to Izuku amends.
 Aizawa wishes that his special mission don't ended like Doom  , but the top villain seal all quirks with his magic, and Izuku was too strong to be totally sealed. Either way, Izuku kills the top villain duo, when the first was with a Venom spell, and the other with the Led Zeppelin:

Ego… Ego… A… Zara… Gorai!… Ego… Ego… Zame... Ragon...
Prince of Darkness and Elder of Evil!… I making the Coronation of the Future Demon King!
May the Germs of Evil be sated by his offering!
Devour the Enemy with Flesh and Bones!
LED ZEPPELIN!

And the villain was eaten alive by several starving demons emerging from several portals opened from Hell. (Doom!) 

9. The SDF brings All Might (just to witness) and Izuku to the a Black Ops Unit at Funabashi JGSDF HQ, where he join temporary the Wild Geese mercenary group composed by vampire versions of Pip Bernadotte (Hellsing), Gara (Bastard!!), Terzieff-Godefroy (Witcher), Serpico (Berserk) and Silver Fang (One Punch Man). 

10. Once Izuku makes some training, he with the Wild Geese are sent to North Korea in order to destroy a research centre of magic weapons. The mission goes wrong, much due to Pip arrogance and strategic mistakes, leaving Izuku and Pip on the edge of murder rampage. After all, it was a phony site, and a consolation prize was a prototype of the Dragon Knight Lucifer Armor DKL-01 (Bastard!!) capable to amplify Izuku's magic  powers, and an endure adversary: The Demon Vampire Zorin Blitz (Hellsing), where also had greater magic powers, and capable to fight against Izuku by equals 

End of spoilers... 

After a long time... 
I start during my Ph. D. to write a program to evaluate nuclear yields 

Basically it's a complex program written in C++ and uses wxWidgets to handle the GUI widgets... (The source-code cannot be resealed yet)
The main propose is to evaluate the yield of a nuclear reaction when a thin foil are bombarded by a proton beam, which energies ranges to 100 to 4000 keV.

However the major problem is the program should handle an array of elements, which parameters are loaded from a database file, and also the program should aggregate some of them in a compound. 

My strategy to code this task as the following:
- I defined three C++ classes to handle the Elements, the Ziegler Parameters to evaluate the Stopping Power and the Detector Efficiency.
- The Database of Elements was defined to form an array (using the wxWidgets built-in array declaration, instead the C++ STL ones, due to the better built-in parameters).
- The calculation sub-routine  mix the previous C++ classes to ease  the job...

And fortunately, I can share a little part of it...

However, exists some errors and the final code was changed sightly, but the basic ideas remains.

_{Edit(Eeems): Merged triple post and moved code to rafb.me}

Chapter published...
https://www.fanfiction.net/s/10496865/1/Hellsing-Special-MIssion-Duel-of-Darkness-on-Levante-Civil-War

A Yu-Gi-Oh game or Cardfight Vanguard simulator on nSpire could be a nice community project, but the small screen of calculator would be something problematic (specially to check the card image, since it will block the screen, and make the gameplay horrific).
Otherwise, just the methods to code thousands of cards (each one requires a code script and a datafile) could easilly overflow the calculator storage quickly, unless a lite version was created.

One little secret: I'm also a fan-fic writer. The first chapter (of three or four) of a mine silly and craziest project has half-done, since it requires a translation from portuguese to english to publish on fanfiction.net archive.
Basically is one of my non-sense parodies mixing the Syrian Civil War, the Yu-Gi-Oh and the Hellsing characters, forming a triple duel of Yu-Gi-Oh between Arucard, Anderson and Integra against ,in the same order, al-Assad, al-Baghdadi (ISIS) and a person who replace the deceased Khomeini. 

So far, I can say that Arucard uses Dark Synchros and Dark Xyz. Bashar uses an Alchemist themed Deck, which the main ace is a Rank 13 Xyz monster called: Chaos Imaginary Number 137 Great Philosopher's Stone  Xyz Dragon.
Anderser uses virtually all Special Summons, al-baghdadi also had their own Special Summons: a PS and XS Summon (A Synchro and Xyz with Pendulum Scale).
Finally, the Khomeini had a Main Deck without monsters, but with a Extra Deck filled with Divine Type Xyz monsters, representing the Twelve Imans of Shia Sect, which should by Rank-Up by their order until it reach the 13th: Mahdi. (Their Duel style was modelled from Zexal's Eliphas).  Integra had a Dragon themed Deck wth Ritual Fusion and Xyz Summon. 

Of course the the end of story was not written yet, but I  think this will be a bizarre way to criticism of this bloodsheed war. 

I think this anime will have a second series this fall.

I get some screenshots to show some amazing capabilities of Maxima, directly fro my Android tablet:

Maxima Start-Up


Making some integrals that HP Prime fail to do so... 
But Maxima can do... 



Now a extreme example, that Maxima can integrate only in some special cases:


This results needs to be scrolled horizontaly to notice the full evaluation:





 

HP Prime and Maxima can be fairly compared in integrals when both can evaluate:



HP-Prime knows the Exponential Integral [wikipedia]Exponential_integral[/wikipedia], the Sine Integral [wikipedia]Sine_integral[/wikipedia], Cosine Integral [wikipedia]Cosine_integral[/wikipedia] fairy well to evaluate the indefinitive integrals listed upward.
 Maxima knows those functions, but evaluates them in terms of Incomplete Gamma Function [wikipedia]Incomplete_gamma_function[/wikipedia].
 Maxima don't know all proprieties of Incomplete Gamma Function, so the HP Prime can make the second indefinite integral using the Sine, Cosine, Exponential Integral Functions, but Maxima left the integral unevaluated 

When a definite integral are applied, both softwares evaluate the same result correctly  . Are both use the Residue Theorem.

To finish the first facing off between HP Prime and Maxima, let's use Maxima to calculate an insane limit that I found in Math Exchange, that use hypergeometric Functions  [wikipedia]Hypergeometric_function[/wikipedia]

So far my concern of the TI policy to lock down the NSpire for third-party applications is only to try make alive the need of a expensive calculator in university.
However in my University (IST), the use of a CAS calculator is pointless 
Even recentelly if exams that requires numerical calcultations, you can bring a smartphone to load a calculator application and use it. 
It's because the professors that teaches the course can check and make caution to avoid cheating between the students, and they think now the calculators of any kind, due to cheap Android phones, are becoming an obsolete technology.
When I make the last exam of introductory Nuclear Physics for my Ph.D. graduate, I use Maxima on Android to solve the calculations with my Samsung Galaxy Mini without problems. The only restrition is to use when is only needed, and then return to the desk openly to professor line-of-view to avoid cheating. (Even in convential calculators you can cheat  )

This means one big thing: why wasting almost €200 for a NSpire CX with a poor CAS, since you can use a smartphone that cost less than €100 which you can install a much better CAS (Maxima), and you can use during classes other powerfull applications ?!
