¿Hey, whatcha doin on this page?

It's just where I put stuff that I'm experimenting on for possible f¯uture use.

To do

I need to find how to do this: https://unix.stackexchange.com/questions/14879/how-to-inject-keystrokes-via-a-shell-script

I need to implement this: https://github.com/JuliaLang/julia/blob/master/base/bitarray.jl

To try

A Fields medallist is at the airport, trying to get from one end of a very long terminal to another. He is trying to get from one end A of a terminal to the other end B. (For simplicity, assume the terminal is a one-dimensional line segment.) Some portions of the terminal have moving walkways (in both directions); other portions do not. His walking speed is a constant v, but while on a walkway, it is boosted by the speed u of the walkway for a net speed of v+u. His objective is to get from A to B in the shortest time possible. Suppose he needs to pause for some period of time, say to tie his shoe. Is it more efficient to do so while on a walkway, or off the walkway? Suppose he has a limited amount of energy available to run and increase his speed to a higher quantity v′ (which is v′+u on the walkway). Is it more efficient to run while on a walkway, or off the walkway?

$$f(z) = \left( \prod_{j=1}^n \frac{z - z_j}{1 - \overline{z_j}z} \right) \left( \prod_{j=1}^m \frac{z - w_j}{1 - \overline{w_j}z} \right)^{-1} g(z)$$



$$ \newcommand{\Re}{\mathrm{Re}\,} \newcommand{\pFq}[5]{{}_{#1}\mathrm{F}_{#2} \left( \genfrac{}{}{0pt}{}{#3}{#4} \bigg| {#5} \right)} $$

We consider, for various values of $s$, the $n$-dimensional integral \begin{align} \tag{2} W_n (s) &:= \int_{[0, 1]^n} \left| \sum_{k = 1}^n \mathrm{e}^{2 \pi \mathrm{i} \, x_k} \right|^s \mathrm{d}\boldsymbol{x} \end{align} % which occurs in the theory of uniform random walk integrals in the plane, where at each step a unit-step is taken in a random direction. As such, the integral (2) expresses the $s$-th moment of the distance to the origin after $n$ steps.

By experimentation and some sketchy arguments we quickly conjectured and strongly believed that, for $k$ a nonnegative integer \begin{align} \tag{3} W_3(k) &= \Re \, \pFq32{\frac12, -\frac k2, -\frac k2}{1, 1}{4}. \end{align} Appropriately defined, (3) also holds for negative odd integers. The reason for (3) was long a mystery, but it will be explained at the end of the paper.

\[  \begin{aligned}
\nabla \times \vec{\mathbf{B}} -\, \frac1c\, \frac{\partial\vec{\mathbf{E}}}{\partial t} & = \frac{4\pi}{c}\vec{\mathbf{j}} \\   \nabla \cdot \vec{\mathbf{E}} & = 4 \pi \rho \\
\nabla \times \vec{\mathbf{E}}\, +\, \frac1c\, \frac{\partial\vec{\mathbf{B}}}{\partial t} & = \vec{\mathbf{0}} \\
\nabla \cdot \vec{\mathbf{B}} & = 0 \end{aligned}

\begin{aligned} \tag{4} \nabla \times \vec{\mathbf{B}} -\, \frac1c\, \frac{\partial\vec{\mathbf{E}}}{\partial t} & = \frac{4\pi}{c}\vec{\mathbf{j}} \\ \nabla \cdot \vec{\mathbf{E}} & = 4 \pi \rho \\ \nabla \times \vec{\mathbf{E}}\, +\, \frac1c\, \frac{\partial\vec{\mathbf{B}}}{\partial t} & = \vec{\mathbf{0}} \\ \nabla \cdot \vec{\mathbf{B}} & = 0 \end{aligned}

That's (4) or (3) above!

Caminante, son tus huellas
el camino y nada más;
Caminante, no hay camino,
se hace camino al andar.
Al andar se hace el camino,
y al volver la vista atrás
se ve la senda que nunca
se ha de volver a pisar.
Caminante no hay camino
sino estelas en la mar.

Escalations of a declining civilization

There are so many ugly, disgusting things happening in the world, I don't even try to maintain a list of these (like Stallman does [1]). Instead, since the Spanish Puppeteers incident—which is about the time I started to feel I should maybe at least voice my reprobation at the most despicable cases—I decided to record those which would escalate one step further from the previous display of tyranny/injustice/oppression/subjugation/enslavement that paces the final days of our civilization. It is, seemingly, doomed for a big financial/societal collapse. It could take years, decades, I might die before the world I was born in does, but we are clearly past the ascending side. In most cases, the incidents illustrate the Ora 25 principle of humanity having surrendered to citizenships, to technical slaves, to people who obey rules and legislation more than humanity and dignity. It starts pretty meekly but I think we'd all agree the escalation is obvious.

Nous autres, civilisations, nous savons maintenant que nous sommes mortelles.
Paul Valery

Spanish Puppeteers jailed for a play featuring a fictitious terrorist organization

Two Spanish artists performing a puppet show for the Madrid carnival, bringing on stage the wrongdoings and abuse of justice, saw their show turn into instant reality by being themselves arrested and jailed without bail for apology of terrorism. The said apology was a highly educated declination in the cryptic Basque language of diametrically-opposed terrorist organizations (so clearly not apologizing for anything). Also weighting in their case, apparently, was a puppet judge being hanged. To me who was born with Brassens' tune l'hécatombe already a nation's favourite, this is a clear proof that there is only finite room for freedom of speech and a highly-regulated right for satire in the 25th hour.

French Police forcefully securing a 72-year-old woman protesting the cutting down of trees

Policing originally meant the regulation and control of a community following the policy of the place. We imagine things like, you won't win anything by stealing from me, since the police will look for you to restore my goods. Or someone is there to interpose themselves if a brute bullies the weak. In the 25th hour, however, police means the arbitrary and non-debatable right of the famous monopoly of violence, to remind those at the bottom of the hierarchy that there are people above. This is achieved by enforcing whatever trifle will serve for that purpose. Latest illustration to date is an old woman displacing a barrier while protesting the cutting down by the council of trees in her street. This was met with a surreal police intervention that sent the granny on the floor, brutally handcuffed with no consideration whatsoever for her great age, her fragility or the innocuousness of her motive [2]. We are now all at risk of being shoved to the floor for the slightest misconduct, such as raising one's voice, taking a picture of something which we are not supposed to or putting a plastic bottle in the paper box. In the near future, that'll come to the point where this is justified by not saying thank you or speaking clearly enough to a police request.

American Police detain, abuse and jail a man driving his wife in labour to the hospital

Our next escalation in the 25th hour involves as offenders a couple rushing to the hospital with the woman in advanced labour [3]. The offence itself is a slightly delayed response to the order of stopping the car, for the time it took them to consider if this was the best thing to do given the situation. They even were in contact with other police force, by phone, from within the car, to take the best decision... after all, the safety of a newborn is at stake, as opposed to a road-police inspection for possible speeding. There is not an additional minute in the 25th hour. Following the phone-police instructions and referring themselves to the road-police, they have been greeted with guns pointed at them. Following the clarification, we all imagine this scene where the police opens the road and escort the precious and sacred convoy. In this case, however, the technical slaves decided to honor the occasion and the breach of regulations by jailing the father, who spent the first hours of his child's life behind bars.

A dog dies after being disposed of as hand-luggage in a plane

A United Airline flight attendant insisted for a dog to be placed in the overhead locker despite the protest of the owner who wanted to keep it by her side in the suitable bag intended for this purpose [4]. The dog died (certainly from stress and suffocation). This is the typical illustration of treating living beings as objects which should follow, against common sense and humanity, the company's administrative procedures.

I once flew with Tizon in a plane (of Lufthansa) and he was very badly behaved at the take-off (barking a lot, despite some drug that we gave him, also intended for this purpose of travelling pets, to tranquilise him). He was extremely stressed. After take-off, he kept quiet and fell asleep. I can imagine how his heart would have burst if instead of me petting him through the net, we had confined him in a black and tight locker, banging against the rest of the luggage. Of course, it was extremely disagreeable to have a dog bark like this in a plane. The waitress even came and told me Sir, please!. There was little I could do. Killing the dog is an option our declining and psychopath society could now envision to preserve the peace of mind of the technical slaves.

A girl gets detained 15 days in the USA after unknowingly crossing the frontier during her jogging on the Canadian border

Not only one should not purposefully do anything wrong in the 25th hour, one should not commit even a sincere mistake, however unimportant, inconsequential or trivial it is. Consequences can, in stark contrast to the of the offence, be arbitrarily tough. A French jogger inadvertently crossed the Canadian/US border during her morning exercise [5]. She would have never known if it was not for the US police arresting her for failing to provide an ID (she was jogging). As she turned out to be illegally on the territory, having only a visa for Canada, she ended up being detained in conditions similar to her having damaged federal properties or molested people to force her way in, when she merely crossed a line through the beach that you only see on a map. Her detention lasted for 15 days and she is now forbidden to enter the United States. In a normal world, she would have been courteously accompanied back with a friendly salutation from the neighbouring nation, maybe with a local gift, a postcard, a cookie. In the 25th hours of technical slaves, she spent weeks in the anguish of imagining to which point this could further escalate.

US Police shoot a pet during a home inspection and harm a little girl standing nearby

In the 25th hour, police is a further threat in situations where you are already in danger. Penetrating a family home to respond to some distress call, a police officer opened fire on the family dog as the latter barked at him, a familiar experience to every visitor of a household with dogs. Not only this insane reaction brings us well into the 25th hour in absence of aggravating circumstances, this further happened with children surrounding the pet [6] Just before the policeman started to shoot randomly in the dark, unconcerned for the safety of the children all around, you can hear him laugh about something. The reported reason for the shooting was that the dog attacked (you can hear him bark) but so violent was the attack and so controlled was the shooting that the dog ended up not even harmed in the process. Only the child suffered from this technical slave's self-defense.

Parce que les gens y nous aiment pas! C'est con!
Parce que nous on est là pour les protéger hein?

Brutal repression of the Yellow-vest movement opens a new era of manifestation

French people are known worldwide for their tendency to oppose reforms by social unrest, and by a generous extension, to revolt against injustice and to resist oppression. That what makes them so special in the eye of Bernanos, and following his gaze, in mine as well. The French revolution is one overhype illustration of the noble expression of this nation in supporting civil and human rights. Its long tradition of demonstration is meeting with a drastic change in the 25th hour: eye removal. The police is using order-maintening tools of the military scale, including hand grenades, explosives and a civilized-looking non-lethal weapon: rubber bullet guns, or so-called LBD, which stands for lanceur de balles de défense (defense-bullet guns). In Newspeak, defence is war and these self-defence mechanisms are actually used to pop-out people's eyes in offensive, deterring and, clearly, inhumanly cruel fashion. There are no fatal casualties yet but these will come, and many people have been already badly mutilated for life. In most if not all cases, this was only for being there in the street, walking peacefully as a form of protest, which is a legal right. This inspired someone to make this humorous reply to a twitter question: - What would you do if you would be immortal for one day? - Demonstrate.

Australian Police arrests pregnant woman at home and in pyjamas for a facebook post

Coronavirus is dangerous, we all know that, it just seems it's dangerous for different reasons for different people. In Australia, a pregnant woman has been arrested in the type of conditions that make people don't believe you when you tell them the story. We see her patronized by the police, which fakes rightful obedience to a legal system and to be dealing with hysteric hostility (when witnesses to the scene are incredibly calm). This happens in front of her children, at home, in her pyjamas, probably causing irremediable damage to the most vulnerable people as defined by everybody's intuition of what humanity is (a woman, a pregnant woman, a crying and begging pregnant woman, a crying and begging pregnant woman abducted from her home, a crying and begging pregnant woman abducted from her home in her sleeping clothes—there seems to be no end to this progression—but also children, babies, fetuses even...) But the technical slave has no humanity, he has warrants instead. The offence in this case is a facebook post, which makes this the escalating step as what could be more harmless and than expressing one's opinion or mood on the social media? I haven't read the post and do not need to, it is irrelevant whatever the context. The questioning starts for me at what type of offence would justify such an arrest... like, if she was suspected of a deadly assault the previous night or to prepare a massive terror attack, would I be as shocked as I am now? She's still at home in her pyjamas... even in the most extreme cases, I would imagine it is possible to show some consideration, if not for her, at least for her baby, her children. But again, we're speaking of a facebook post. One should not, in the 25th hour, stray in the slightest from the established rules, even if those are supposedly for our own safety in the first place. And we also know that it does not matter if you were not even aware of the rules or offering to repay the "offence", as was the case here. In the 25th hour, human beings must be jailed.
