Just kidding again!
A language is a tool. You should pick the best tool for the job you want to accomplish
...that being said I'm most efficient in python for most tasks I do, but the languages that really fascinate me are the ones that allow you to extend their syntax (like forths and lisps).

I enjoy C because it is simple, is capable of doing anything to a reasonable degree of competence. Its also extra fun since it allows lower level bit twiddling without having to be completely stuck with unabstracted computer bullshit.

Lua is nice because its simple and easy, it reads like english and is easy to comprehend both what a program is doing and what I should write next. Its very satisfying to write lua since it is the closest thing to instant gratification you can get with programing.

My opinions vary depending on what I am doing, currently I am using lua and C for a project so I will be bias towards these 2 languages; when I was doing webdev I thought PHP was the best thing since they invented cats
COBOL is fun too sometimes; I think it gets more shit than it deserves

The case for ancient Egyptian impulse electricity.

Okay first whats 'impulse electricity'.

Many will know E=Mc^2. Given this mass-energy equivalence you can plug in Energy inside the gravity equation F=Gm1m2/r^2.

Electric Charge has energy. Charge density maps to energy density. Gravity can be modelled as the collapsed of the geometry of the underlying medium, giving the appearance of a force.

Impulse electricity is the art of generating very short bursts of electricity to create moments of incredibly high energy density.

Despite being the popularizer of Alternative current, with his polyphase system practically taking the world out of the dark age. He dropped AC rather quickly to spend the rest of his life investigating Impulse Electricity.

An experiment he brought forth with him where ever he lectured is a sort of inception on the topic. the experiment is known today as 'stout copper bars' or the 'tesla hairpin circuit'. It has numerous interesting effects. Despite it being of very high voltage, you can touch it without harm. You can pass it through water without it shorting, to name a few. And it is a window to impulse electricity. I suggest everyone to check it out.

Among Tesla's many patents on the matter of Impulse electricty, and radiant energy is patent 787412. Which describes basically using earth like a bell to transmit energy to the globe. The features in the patent also indicate its use in navigation, and thus cartography. This is where things get quite interesting.

You see the Piri Reis map. Compiled 100's of years before we had supposedly had any ability to create proper longitude, maps south america, and ice free Antarctica near perfectly. Cartographic analysis by Tom a megalithology on youtube points to its centreing around Giza. And that it does not conform to any known map projections. Many speculate that Piri Reis is a copy paste of source maps of Antiquity.

Tesla, Giza, Navigation, Impulse electricity. I'm sure you've heard it before. Could it be that the pyramids are a ancient 787412. And that it made nodal regions of the earth vibrate sistrums?

>What would they need impulse energy though?
Global wireless energy transfer like in your video related.

Impulse electricity delivers a different type of electromagnetic wave than radio and cell phones. That stuff vibrates at right angles to the direction its travelling. It is transverse. Electrical impulses of sufficient energy, not oscillating from +V to -V but +V to 0 deliver waves that vibrate in the direction of motion, they are longitudinal, density waves.

These longitudinal waves do not 'get caught' on the medium, losing energy by creating magnetic fields by induction. Thus they can travel without losing energy. Even through faraday cages. Devices such as 787412 and 685950 - 59 utilize impulse electricity to create longitudinal emf. These are handy for wireless deliver of power.

I hypothesize the egyptians used them make their tuning forks buzz, and piezoelectric quartz buzz. Tools such as sonic drills, and perhaps even acoustic levitation was employed by having these devices simply sit in the field. 787412 lays out the case for accurate mapping of the globe without sea worthy time keeping pieces

>what they could do with that technology.

It starts with trying to drill quartz, a popular building material for that time, and seeing the light come out of it. And devoting a priesthood to studying the phenomena, creating even music to make the crystals light up.

I cannot help myself, I MUST post lovecraft
>The most merciful thing in the world, I think, is the inability of the human mind to correlate all its contents. We live on a placid island of ignorance in the midst of black seas of infinity, and it was not meant that we should voyage far. The sciences, each straining in its own direction, have hitherto harmed us little; but some day the piecing together of dissociated knowledge will open up such terrifying vistas of reality, and of our frightful position therein, that we shall either go mad from the revelation or flee from the deadly light into the peace and safety of a new dark age.
>Theosophists have guessed at the awesome grandeur of the cosmic cycle wherein our world and human race form transient incidents.
>They have hinted at strange survivals in terms which would freeze the blood if not masked by a bland optimism. But it is not from them that there came the single glimpse of forbidden aeons which chills me when I think of it and maddens me when I dream of it.

Speaking of lovecraft, He did have an interesting idea of aliens. Fungal, Animal and even mineral mixes that's hard to classify yet aren't animalistic in nature dispite looking bizarre. It was more sinister, if anything. Humanity was no more then a mistake turned science experiment/toy and food source for them. We ended up on earth by accident and the elder things ended up warring with other aliens for control over earth, also they slowly lost some of their abilities due to earths gravity and the only thing they can do is just hide. In the extreme case of The Color Out of Space, The alien was no more then some type of light/color that drained everything of life in order to survive (although i doubt something like that could live long)

Op here, just wanted to say that I hate dates to death.
In java (my backend language) there are 3 different built-in time libraries/types (For exact moments: java.sql.timestamp, java.util.Date, java.time.Instant)
But in case that wasn't enough, the most recent and recommended module, java.time, has a fuckton of different types of close meaning
>java.time.Instant - an instant in time
>java.time.ZonedDateTime - Also an instant, this time with timezone information
>java.time.LocalDateTime - Generic date and time, NOT a definite moment (depends on timezone, which is not stored)
>java.time.ZoneOffset - Literally a timezone offset. Not a timezone though! A single timezone can have two offsets due to dst
>java.time.ZoneID - This here is the Timezone
At this point I had gotten what I needed and thought my trials with dates were over. But then came javascript
It has just one type, Date, however it sucks fucking ass. All I want is for my application to assume "CET" timezone when reading and printing dates/times. Well, javascript's Date type doesn't have timezone info, instead that is used when printing/reading the date. Fine. But definitively it'll be easy to do that, right?
Well, JS just assumes your browser knows what's best, and if your browser has the wrong timezone setting... well suck a dick. And firefox browsers have wrong setting on purpose to fight trackers. Am I fucked? Well, there is a built-in library called "Intl" that allows for the programmer to work with timezones, but then older browsers go out the window. IE for example doesn't support jack shit. Why does this have to be so hard? Do I really need to plug in some third party "moment.js" library or implement timezone functionality myself?
Course not, fuck IE

 No.540[D][DF]

>>539
Small update: Intl is nothing more than a pretty print library. It's not actually usable for anything but printing stuff to the user.
I'll be implementing DST logic myself, thanks for sucking cocks javascript

So I've been thinking about switching to qutebrowser recently, and it's almost perfect for me. There's a couple issues like no Ublock Origin but I can get over those.
However, navigating 22chan doesn't work properly.
Opening a link to a post(such as >>2527 ) does nothing when I do it with the keyboard(press 'f' and choose the hint). I expect it to show me the post when I click on it, but instead it highlights it off-screen and I have to scroll down manually and find the highlighted post. Doing it with the mouse works for some reason. I'm switching to qutebrowser so I could do everything with the keyboard, so I might as well use firefox if that's the only way.

Any qutebrowser anons who've solved the issue?
