Everyone is going on about how suddenly finding a programming gig is or has become a lot harder why with the outbreak and the economic downturn it is going g to cause.

But realistically is it true? Did I just pick a bad time to start a new career in this particular field or is it just FUD?

At the dentist AGAIN. This time a proper oral surgeon. Informed me they are ONLY doing novacaine today when the referring dentist said I would have to be put under ffs. It's like these people don't listen.

I wonder if I can get a refund when they *also* realize I don't respond to novacaine.

If any of you were wondering why all the panic when we keep hearing reports of so few people personally knowing anyone with covid19 symptoms, I think I just figured out why.

So as of yesterday, assume unofficially fatality is 15%. Yesterdays death total was 3861.

If we assume roughly 15% death rate, based on ten days average for a case to recover or die, then the cases that would be recovering today on april 1st would have been infected or started to show symptoms on march 22nd.

At that time there was 32882 cases total in the u.s.

Therefore for april 1st, that would mean by the end of the day today, if the ~15% fatality rate is accurate, there would be at least 4,932 fatalities logged today.

I don't know about you, but here it's almost 9am, not even halfway through the day, and we're already at 4067 deaths.

And now we get to the part where all this shit starts to make sense.

For a long time since this outbreak has started somethings been bugging me and I couldn't place what it was till now.

Why did it seem, no matter how high the numbers climbed, no matter how much this spread 'like the flu', no matter how hard I looked into it, very few people seemed to personally know anyone *in real life* who died or at least came down with this?

I mean we'd all heard the rumors that it was more lethal, and then mums the word, it seemed like media the world over simply except the official "it's only 2% lethal" line. Same as the line about it only infecting people of asian descent.

And it didn't make sense to me why the numbers were so high, and why all the panic if it's just the flu? I knew in the back of my mind it wasn't I just didn't have a specific reason why.

Here it is: This thing is still pretty contagious, but not as contagious as it *could* be with a lower fatality rate. And with a fatality rate at 15%, combine with *just sufficient* spread, it would continue to burn and fester in communities for a year or more until those panic-numbers we see on the news would become a real thing. And then no matter HOW flat we made the curve, it would be x5-x50 times worse than a bad flu.

So we get panic and fake numbers. Because you really don't want to catch this thing. It kills 1 in 6.6. And it spread just enough that it is hard to effectively fight.

Currently at dentist getting wisdom tooth pulled. Nervous as hell.

My outlook for when this pandemic is over, at least in the u.s. : 10-15 days.

It'll end with between 14k and 20k deaths.

Math question time!

Okay so I had this idea and I'm looking for anyone who has a better grasp of math than me.

What if instead of searching for prime factors we searched for a number above p?
One with a certain special property. BEAR WITH ME. I know I make these posts a lot and I'm a bit of a shitposter, but I'm being genuine here.

Take this cherry picked number, 697 for example.

It's factors are 17, and 41. It's trivial but just for demonstration.

If we represented it's factors as a bit string, where each bit represents the index that factor occurs at in a list of primes, it looks like this

1000001000000

When converted back to an integer that number becomes 4160, which we will call f.

And if we do 4160/(2**n) until the result returns
a fractional component, then N in this case will be 7.

And 7 is the index of our lowest factor 17 (lets call it A, and our highest factor we'll call B) in our primes list.

So the problem is changed from finding a factorization of p, to finding an algorithm that allows you to convert p into f. Once you have f it's a matter of converting it to binary, looking up the indexes of all bits set to 1, and finding the values of those indexes in the list of primes.

I'm working on doing that and if anyone has any insights I'm all ears.

The Sorry State of Web programming (and who should be punished for it)

"And if you’re really lucky, and your following grows to scientology-levels of fanaticism you may get your own con. Yes con. Like DockerCon, or JsCon, or LongConJs, because thats exactly what all this is — and it’s exactly what we need: more excuses to meet up for the already sterile pollination of bedfellows, the unwashed, unvarnished masses of guys in their 30s, obsessively stroking their perfectly manicured beards and arguing over the comparative differences between vim versus emacs while completely oblivious about things like how you’re supposed to wear an undershirt with your button up. If not for hackathons, and ted talks, and sxsw, and conferences, and SomethingCons, and ‘retreats’, and dozens of other pointless synonyms for ‘people just meeting up’, most of us would still be in our cubicle, office, or room, typing away instead of socializing like normal people."

Full post here because I like to insert pictures because like all normie fucking simpletons I like pictures in my books.

I think I found the equivalent of 'square root' but for modular arithmetic.

This is kinda stupid cuz I only tried it on two numbers so far but feel free to try it yourself and prove me wrong!

Take √p

Then divide √p by 2, 3, 2, 3, repeating until the result is below 2.

Now take that chain of divisions and tack it onto p instead, then change all the 2's to 3's.

Lets call our new result 'r'

Now do

p%r

and the result should be the same as r.

For example

√697/2/3/2/3/2 = 0.3666771884012246

So our chain is 2/3/2/3/2

Now change all the twos to 3s, so we get
3/3/3/3/3. And somewhere within the range
of 3**0 to 3**N is our 'modular root'

Then

697/3/3/3/3 = 8.604938271604938
or
697/3**4

And finally

697%8.604938271604938 = 8.604938271604938

Likewise, if p = 345852581

√p/2/3/2/3/2/3/2/3/2/3/2 =
1.1958019655536958

p/3/3/3/3/3/3/3/3/3/3/3
1952.3479426690828

p%1952.3479426690828
1952.3479426511476

Which admittedly isn't the same but I think might be a rounding error.

In either case it's interesting. Has anyone seen this before and if so where can I learn more?

Apparently my learning style is more rote memorization than learn-by-doing and I've been trying to learn by doing for years as a hobbyist.

It took a fucking *national quarantine* to get me to try something different and I'm blown away.

What would have taken me many months to learn I've all but grasped in detail in a matter of 20 hours of study over the course of a week.

Fuck you javascript. I WIN THIS ROUND. No more looking at the documentation for stupid shit like how to write a regex, or why everything is wrapped in fucking parenthesis (IIFE), or why
I keep getting a uncaught reference exception.

The important thing to realize about learning is NEVER be obstinate about it. Try many things, and don't get stuck in one way of learning unless you know thats what works for you.

This is why having study partners and mentors are important.

I think experience/practice and rote learning work in tandem. Rote learning lets you skip the much longer step of grasping the fundamentals, bootstrapping the process of learning the abstractions that are composed of those fundamentals.

I'm still adding cards to my anki flash card deck, but if anyone wants it I'm willing to share. It's mostly just 1. practice questions, 2. detail questions (what are the types? What does this regex do?, etc), 3. implication questions (heres this bit of code. It's XYZ, why did it fail? Correct it.), combining core details to memorize, and the application of the facts learned.

It helped me to learn and I'm apparently retarded, so if you're new to programming and want to learn JS, it can probably help you too. Unless you're more of a tard than me lol.

I'm literally in pain right now and not a thing I can do.

If I eat whatever the fuck is wrong with my jaw (cracked tooth or cavity) starts throbbing from the chewing action, in addition to coming on for no reason at all. vision-blurred-waves-of-nausea levels of pain. Enough that I'm alternating between laughter and almost tears.

I've downed four aspirin and it's still just barely enough WITH the numbing gel.

Got lock jaw something aweful.

Barely convinced a dentists office, which is supposed to be closed (and cancelled all it's appointments due to corona), to come in during quarantine. But thats monday. Dont kno how I'll make it. They do payment plans but I'm flat broke because I decided to pursue programming right when all this fucking bullshit went down.

And all I can think of while im typing this is the pain.

And fuck me I cant do weed because my backup plan if I fail at coding is the military.

And this stray dog that the neighbors 'adopted' but leave outside WONT STOP FUCKING BARKING.

Fuck me. Just kill me now. Do it.

Gonna go watch comedy because I read a research paper that says genuine laughter raises pain threshold by up to 10%.

People are so afraid right now, you could rob a bank with a booger.

More math (because it's 5am and currently the apocalypse so why not).

e - log(log(e, 1.444667861009766**1.444667861009766), log(e, e**1.444667861009766)) = 1

I've been studying so long if I happen to glance at a pocket calculator I might jizz in my pants.

Thinking BigBrain thoughts right now bois! (tm).

Oh shit. Cant stop. I think I opened a portal bros! and am being sucked in. ITS A BLACK HOLE!

This is how to find the base needed for any integer value p, where p>=5, such that the logarithm always equals e in python.

log(p, e**(log(p, e**e))) # equals e

Doesn't do anything besides that but this is another identity isn't?

is this what they call an identity?

log(n, n**(1/n)) == n

first argument in log is the value
second argument is the base

More masturbation with numbers.

If you take some product p,
and do

√p**(1/p)

and it's factors

a**(1/p)

and

b**(1/p)

you might find something interesting.

Take for example

a=21977
b=43331
p=a*b=952285387

(√p)**(1/p) = 1.0000000108551363

a**(1/p) = 1.0000000104986928
b**(1/p) = 1.0000000112115799

More often then not, a, b, or both, will share one or two of the most significant digits in the mantissa, as the root of p.

It doesn't always work, but it seems to be true more often than you might expect.

This is probably obvious in hindsight but I still think it's cool.

In some instances if you then do, say
sqrt(log(p, 1.000000010)), it comes pretty close to the original factors, but thats really hit or miss.

Oh god, here comes another math post! I can feel it coming on, like werewolfism during the full moon.

I'm only passingly familiar with logarithms, so this, like everything I've stumbled on, has probably already been discovered, but

n/(1/((n^(1/n))-1))

Is a pretty good approximation (within a couple percentage points, or three or more digits) of the natural logarithm for all the numbers I've checked it on.

For example if

n = 690841693

ln(n) = 20.35342125707679

while our estimate using the above formula comes out to:

n/(1/((n**(1/n))-1)) = 20.353421612948146

Am I missing something obvious here, and if so, what?

Am I doing the idiot savant thing again, or am I just being an idiot again?

Some of you know I'm an amateur programmer (ok, you all do). But recently I decided I'm gonna go for a career in it.

I thought projects to demo what I know were important, but everything I've seen so far says otherwise. Seems like the most important thing to hiring managers is knowing how to solve small, arbitrary problems. Specifics can be learned and a lot of 'requirements' are actually optional to scare off wannabes and tryhards looking for a sweet paycheck.

So I've gone back, dusted off all the areas where I'm rusty (curse you regex!), and am relearning, properly. Flash cards and all. Getting the essentials committed to memory, instead of fumbling through, and having to look at docs every five minutes to remember how to do something because I switch languages, frameworks, and tooling so often. Really committing toward one set of technologies and drilling the fundamentals.

Would you say this is the correct approach to gaining a position in 2020, for a junior dev?
I know for a long time, 'entry level' positions didn't really exist, but from what I'm hearing around the net, thats changing.

Heres what I'm learning (or relearning since I've used em only occasionally):

* Git (small personal projects, only used it a few times)
* SQL
* Backend (Flask, Django)
* Frontend (React)
* Testing with Cypress or Jest

Any of you have further recommendations?

Gulp? Grunt? Are these considered 'matter of course' (simply expected), or learn-as-you for a beginner like myself?

Is knowing the agile 'manifesto' (whatever that means) by heart really considered a big deal?

What about the basics of BDD and XP?

Is knowing how to properly write user-stories worth a damn or considered a waste of time to managers?

Am I going to be tested on obscure minutiae like little-used yarn/npm commands?

Would it be considered a bonus to have all the various HTTP codes memorized? I mean thats probably a great idea, but is that an absolute requirement for newbies, or something you learn as you practice?

During interviews, is there an emphasis on speed or correctness? I'm nitpicky, like to write cleanly commented code, and prefer to have documentation open at all times.
Am I going to, eh, 'lose points' for relying on documentation during an interview?

I'm an average programmer on my good days, and the only thing I really have going for me is a *weird* combination of ADD and autism-like focus that basically neutralize each other. The only other skill I have is talking at people's own level to gauge what they need and understand. Unfortunately, and contrary to the grifter persona I present for lulz, I hate selling, let alone grifting.
Otherwise I would have enjoyed telemarketing way more and wouldn't even be asking this question. But thankfully I escaped that hell and am now here, asking for your timeless nuggets of bitter wisdom.

What are truly *entry level* web developers *expected* to know, *right out the gate*, obviously besides the language they're using?

Also, what is the language they use to program websites? It's like java right? I need to know. I'm in an interview RIGHT now and they left me alone with a PC for 30 minutes. I've been surfing pornhub for the last 25 minutes. I figure the answer should take about 5 minutes, could you help me out and copypasta it?

Okay, okay, I'm kidding, I couldn't help myself. The rest of the questions are serious and I'd love to know what your opinions are on what is important for web developers in 2020, especially entry level developers.

Ooooh MOTHERFUCKER. God fucking dammit. Jesus FUCKING christ. Motherfucking local caching on firefox and chrome. Reload the MOTHERFUCKING PAGE, it's why I pressed CNTRL R you fucking blighted cunts.

Some days I wish I had a brick to toss at the fucking head of the nearest chrome/firefox developer.

Fucking assholes. Eat shit and die alone of cancer fucksticks.

So, forgive my ignorance, this isn't a troll just a question.

How are continued fractions related to modular arithmetic?

Take the following example:

70%32 = 6
70//32 = 2

which we can just represent as
6+(32*2)

Now, as a continued fraction, we would do

70/32 = 2 + 6/32
and repeating what we just did but for 6/32, as you would with a continued fraction.

Am I actually doing everything correctly here or am I missing something?

Faster square roots?

Did you know if you multiply your
product by pi, and then use that as
the area of a circle while solving for
the radius, the result will be an
approximation of the square root
of your product.

Example:

let p (the product) = 492181
then √p = 701.5561274766261

492181*pi = 1,546,232~
(leaving off the fraction for
the sake of brevity)

area = 1,546,232

then the radius of the 'circle' would be 701.56

I wonder if anyone has stumbled on this before?

Much obliged if you stop reloading the folder and searching it every five fucking seconds you fucking cunts.

Good god damn this fucking 'feature' of windows 10 grinds my fucking gears. I hit 'x' to stop seeing the visual distraction of the fucking green loading bar when the folders already loaded. Same thing with music. All I want it to do is open and play my fucking song.

Does it do that?

No instead it spends precious cycles updating fucking indexes or sprinkling crack rocks on the corpse of my cpu or whatever cycle fairies at fucking microsoft programmed it to do while wasting my fucking time.

I wish I had a brick and a microsoft programmer within throwing distance, I'd be sorely tempted to nail the motherfucker square in his fucking big fat melon.

(n/x)*(y/x)

You know x, and you know n, and you know z where ((y/x)*x)*((x/y)*x) = z

Solve for y.

If you do it, I'll consider giving you a billion dollars (of course the payment schedule will be an asymptote).

P=NP

Change my mind.

If we can transform the search space or properties of a product into a graph problem
we could possibly use Kirchhoff's theorem to reveal products which are 'low complexity'
in particular search spaces, yeah?

Now according to
https://en.wikipedia.org/wiki/...

"n Cycle Space, A family of sets closed under the symmetric difference operation can be described algebraically as a vector space over the two-element finite field Z 2 {\displaystyle \mathbb {Z} _{2}} \mathbb{Z } _{2}.[4] This field has two elements, 0 and 1, and its addition and multiplication operations can be described as the familiar addition and multiplication of integers, taken modulo 2"

Wouldn't this relate to pollards algorithm, because it involves looking for factors of coprimes modulo N or am I mistaken?

Now, according to wikipedia, "in a group, the additive identity is the identity element of the group, is often denoted 0, and is unique."

If we make the multiplicative identity of our ring or field a tuple of the ratio of a/b for some product p, or a (and a/w, where w is the square root of p), or any other set such that n*m allows us to derive a or b, we could reduce the additive identity to the multiplicative identity, making the ring trivial. Solving for p would then mean finding a function from R to R, mapping every number to 0, i.e. finding the additive identity.

Now in a system with a multiplication operation the distributes over addition, the "additive
identity annihilates ring elements", so naturally, the function that maps to 0, gives us
our additive identity, we need only find the subset, no?

Forgive me if I'm wrong, but shouldn't this be convertible to a graph search?

I'm WAY out of my depth here so if anyone is familiar and can enlighten me I'd be grateful.

It's all unknown unknowns to me.

"A King"
a king came to me one day
and claimed you will be my son!
and fame, and fortune, and all things good
yours your cup to overflow, overrun!

happiness and princesses, acclaim to your name
a life of leisure and of ease
land rich in treasures buried,
and swarthy ships on deep seas!

All these things, of emperors and kings
Will be yours to command! Though I warn
you my fair son, it is not as it seems
a charmed life is not grand

for though the riches of this earth
at your call, at your hand,
should find you at my passing, in your wealth
it is a kings fate to be damned

wealth to grave you can not take
and princesses demanding wives are one to make
and ships in harbor soon they rot
and health in age gives way to ache
and land is lost which once hard fought
truly that is rare the happiness which can be bought!

so upon the kingly head, heavy rests the (golden) crown
and though surrounded by apparent friends
never must he let his guard down

and ease which spoiled by fear of loss
magnified by all he'd gained
weary king, my boy, tis his lot,
to die a thousand times,
but never grow old again,

so heed these words my boy
it is not the wealth, or fame, or ease
that makes a man great my son,
but his words and his deeds!

If you look around you'll see this wherever you turn your head. On the news? People lying like a mothafuka for their job. People selling something on tv? Billboard? internet? Lying like a mothafuka. People in fancy suits with fancy pieces of cloth tied around their neck to tell you who the master holding their dog leash is? "I did not kill that hooker", "We have to sign the law to know whats in it", "These ratfuck starving terrorhobos huddled inside a cave out in buttfuck nowhere, saudi arabia? They made a nuclear bomb!". Lying..like a mothafuka.

And all of them have careers, or jobs, or some cause, or principles they 'believe' in. Or nation they 'serve'. Or any other justification, any other *excuse*. But really thats all it is.

In this great big universe, you didn't exist for billions, possibly trillions of years, and now you do, for a brief span, and then afterward, you'll cease to exist (maybe, who knows what happens after death?), for more billions or trillions of years.

Put on that scale, no utterance out of your mouth *can* or *will* ever really truly matter. at all.

Napoleon said "Imagination Rules The World". Of course he also said a bunch of other things, mostly (all) in french. I don't speak french. But why live in ordinary reality when countless others do?

Some days I can't get over the cynical gnawing outlook that everything is shit and nothing gets better and it's all down hill, thats theres no real future for any of us, no stability or careers that won't vanish or be replaced or outsourced. That the entire economy in the west runs on fraud and lackyism and bullshit and a revolving door of never ending hype and marketing.

Somedays I feel like I'm just waiting to get old and die.

Maybe this cynicism and pessimism is born from a period I went through from 2008 when I was just turning 18 to 2013 when I lived with my parents and went through several shit jobs where I was essentially disposable. But the entire situation and the bad start in life has left me with a gut feeling that nothing really matters and it all can vanish over night or be taken away.

Sorry to be a downer, just some days I can't see what the point is.
