No entendí lo de vender programadores por kilo

mortal dagger Nov 14, 2019, 6:26 PM

#

basicamente, las empresas que tienen 3.000 programadores venden proyectos a las empresas y te dicen "vamos a poner a 100 desarrolladores en tu proyecto" y cobran por eso

ashen mist Nov 14, 2019, 6:26 PM

#

Oh, eso

mortal dagger Nov 14, 2019, 6:26 PM

#

cobran el sueldo de 100 personas

#

y el proyecto lo hacen 2

#

las otras 98 personas solo están ahí haciendo bulto

#

Yo usaría ese tiempo para una startup

mortal dagger Nov 14, 2019, 6:28 PM

#

es que las primeras semanas es entretenido

#

ahí está el truco amigo, no puedes hacer una startup por contrato

#

todo el código que generes dentro del periodo donde estás trabajando es propiedad de la empresa

#

y te hacen firmar una cantidad absurda de papeles

#

pero al tiempo frustra, de esas empresas siempre sale gente con ansiedad, depresión, frustrados o técnicamente poco hábiles

#

porque pierden la costumbre

#

antes había una página que se llamaba devpressed, que eran devs con depresión y estaba lleno de historias así

#

gente de oficina de 9 a 5, sin mucho trabajo que hacer, ganando bien y de repente se sienten vacíos e inútiles

#

o también está el caso contrario en estas mismas empresas, que les dicen "moledoras de carne"

#

que venden proyectos con tiempos de entrega en 1 mes por ejemplo, sabiendo que el desarrollo se demora mínimo 3 meses

#

esas empresas son famosas por comprar pizza y tener taxis a la salida todos los días

#

porque cuando estás por salir te dicen "oye, estamos cerca del deadline, ¿por qué no te quedas un rato? te vamos a dejar a la casa y compramos comida"

real imp Nov 14, 2019, 6:34 PM

#

Pero no que te sacan el startup sí y sólo si usás la infraestructura de la empresa?

#

Así pasa en la serie Silicon Valley

This was time ago

I had a raspberry pi

With XBMC(?) installed as the OS

#

You can set repos as a source for media and I found one full of literally everything

#

Just search for a series and it's all there

#

Eventually that repo got shut down but I found a new one

#

As is the life of a pirate @glass dragon

glass dragon Nov 14, 2019, 10:11 PM

Oh ok I didn't know there were repos. And then was there some user interface that you installed for it?

gentle heath Nov 14, 2019, 10:11 PM

The interface was XBMC

Here’s the bad news: As far as we can tell, occasional high CPU usage from the Windows Modules Installer Worker process on Windows 10 is just normal.

The good news is that, if you allow it to run, the process will eventually finish and stop using CPU and disk resources. The Windows Modules Installer worker process will finish and it will disappear from the running processes in Task Manager. How long it will take depends on the speed of your computer’s CPU and storage, as well as on how many updates it needed to install.

BRUH IVE BEEN WAITING FOR FIVE MINUTES

#

will it reset when i startup my pc again

ashen mist Nov 15, 2019, 10:15 PM

#

5 minutes for a windows update? you must be new

#

You’ll see some bad advice online recommending you should disable the Windows Modules Installer system service to prevent this from happening. This will prevent Windows from installing updates properly, and you shouldn’t do it.

Similarly, others may recommend setting your network connection to “metered”, which will prevent Windows 10 from automatically downloading and install many updates. This will prevent the Windows Modules Installer process from activating, but your computer won’t install critical security updates that can protect you from malware like the WannaCry ransomware, which exploited a bug patched two months before it was released. Avoiding operating system updates is dangerous, and we don’t recommend it.

Sure, you could install updates manually—but the Windows Modules Installer Worker process will run after a manual update, anyway. It’s probably best to just bite the bullet and allow the TiWorker.exe process to occasionally do its thing. This is just how Windows installs updates, and it’s for your own good.

if it's actually just installing updates, let it finish

mossy cloud Nov 17, 2019, 4:33 AM

#

How's your calc teacher?

gusty ermine Nov 17, 2019, 4:35 AM

#

i feel like the class i am taking is more of independent study rather than learning in class. My teacher is really nice but most of the things we have to figure out on our own or ask him for help. Literally everyone is behind (luckily I got caught up on homework today because I went to school and asked my teacher for help) and I can't help but feeling so dumb.

mossy cloud Nov 17, 2019, 4:35 AM

Oh yeah, definitely

My friend who is Chinese and I (Korean) decided that we are not worthy to be asians

mossy cloud Nov 17, 2019, 4:37 AM

#

It's unfair for other people to hold us (I'm asian too, Vietnamese) to that stereotype, so it's unfair for us to hold ourselves to that stereotype too. But it's not that you're bad at it. I think you just need to learn how your brain learns and thinks too

#

And asking questions will always be your friend

real imp Nov 17, 2019, 4:40 AM

Lmao but that's an awesome stereotype

#

I wish I was seen as smart just from my looks

#

I dont think there is a better compliment than that, racist or not

#

Though I do get that it could get old

gusty ermine Nov 17, 2019, 4:41 AM

#

It is a joke but also I am the ultimate asian stereotype. I play piano (classical piano since I was really young), flute, tennis, and chess. I am fairly good at school and involved in tons of activities. I joke about it, and it's kinda sad and funny at the same time. I used to be good at math (hecking calculus).

Yeah you play the piano well

gusty ermine Nov 17, 2019, 4:42 AM

mossy cloud Nov 17, 2019, 4:46 AM

#

I'll tell you this @gusty ermine , your class may feel like independent study, but teaching yourself calculus isn't impossible. Feel free to ask me about my experiences with independent study. I'm willing to bet that the way you've been studying math before (algebra, geometry, etc.) was flawed from the beginning. In calculus, it's more about conceptualizing, visualizing, and understanding; it's not the computational chore the comes with algebra.

#

I've also learned more from 1 year of independent study (my senior year) in all of my 4 years in high school

real imp Nov 17, 2019, 4:47 AM

#

I wish I could learn calculus too

#

I have struggled with math every since 4th grade in elementary

mossy cloud Nov 17, 2019, 4:48 AM

#

When you learn that you control your own education, you quickly realize how meaningless grades really are

#

Khan academy

#

is also a great resource

gusty ermine Nov 17, 2019, 4:49 AM

#

I never really learned anything in math class. Our school doesn't have the best math courses and we would have 15 minutes of free time every day and I would finish my work within 5-10 minutes. I like math, but I don't really know how to study it. I got good score on my SAT math, so I was satisfied, but I feel like calculus is so different.

mossy cloud Nov 17, 2019, 4:50 AM

#

How motivated are you to learn calculus?

#

I could give you a bunch of tips, but it would be meaningless if you weren't 100% into it from the beginning

real imp Nov 17, 2019, 4:50 AM

#

My biggest flaw is not just maths, its that I still havent figured out how to study

#

And it is both my fault and the systems fault

#

Because elementary and highschool were just so easy I never had to study

gusty ermine Nov 17, 2019, 4:51 AM

#

I was always good at math, it came easy and I was always the best in my class. I try to take the best classes in my school and ap calculus was the highest math course our school had, and I was qualified for it, so I took it.

#

I need to take the AP exam for calculus at the end of the year, so I am pretty desperate to understand every concept.

mossy cloud Nov 17, 2019, 4:52 AM

#

AP exam is difficult, I'll tell ya

#

But you still have time

#

Don't stress over it too much

gusty ermine Nov 17, 2019, 4:53 AM

#

@real imp If the courses aren't hard enough, I usually overburden myself with tons of courses and things to do so I have to do things. Not the best way, but one way to go.

mossy cloud Nov 17, 2019, 4:53 AM

#

Learning how to study is a very important thing, yes. I'd say that there needs to be a class on it, but we all learn differently

gusty ermine Nov 17, 2019, 4:54 AM

#

I feel so behind

#

why is life so tough

mossy cloud Nov 17, 2019, 4:55 AM

#

It's okay to feel confused. In fact, that's a great thing; it means you're learning. I prefer to be confused rather than know everything. The difference is that I try my very best to understand every fundamental detail and concept of the thing I'm confused about

#

So you're confused right? Where are you confused? Limits? Derivatives? Theorems?

real imp Nov 17, 2019, 4:56 AM

#

@gusty ermine I wish I had done that. Instead I just kept playing videogames...

mossy cloud Nov 17, 2019, 4:56 AM

#

Oof, I recently quit videogames

real imp Nov 17, 2019, 4:56 AM

#

I did a lot of things, music, languages, sports

#

But school was just too easy anyway

#

Even if I was busy all day

#

@mossy cloud why?

gusty ermine Nov 17, 2019, 4:57 AM

I am currently learning about derivatives: chain rule and derivatives of inverse trig functions. I keep forgetting one step or another.

mossy cloud Nov 17, 2019, 4:59 AM

@real imp I quit because it was taking up a huge portion of my time and I wanted to pursue my career of becoming a physicist

You're just missing the chain rule

#

Ah

So, for your derivative

#

You only learned how to take the derivative of arccos(x)

arccos(1/x) is a composite function

y=arccos(u)

u=1/x

mossy cloud Nov 17, 2019, 5:15 AM

Before we touch derivatives

Let's think about slope

If I have a graph

#

#

Slope just measures the rate of change of one variable based off another

gusty ermine Nov 17, 2019, 5:25 AM

#

right

real imp Nov 17, 2019, 5:25 AM

#

Imagine inventing these stuff

mossy cloud Nov 17, 2019, 5:26 AM

#

The slope is basically the average velocity of an object moving from point a to point b in a given time b

gusty ermine Nov 17, 2019, 5:26 AM

#

distance / time?

mossy cloud Nov 17, 2019, 5:26 AM

#

yes

#

Our horizontal axis is our independent variable

#

Slope measure how much the dependent variable changes per one unit of the independent variable

#

say your slope is 5/2 m/s

#

That's 2.5 m/s

#

For every one second, you move 2.5 meters

gusty ermine Nov 17, 2019, 5:28 AM

#

yes

mossy cloud Nov 17, 2019, 5:29 AM

#

And going back to our original graph

#

a vs. b

#

Say that's the amount of apples you eat per banana (it's random, ik, but it fits the letters)

#

Your banana is your independent variable. You are concerned about how many apples you eat per banana

#

So we understand that slope just means rate of change, yes?

gusty ermine Nov 17, 2019, 5:30 AM

#

yes

mossy cloud Nov 17, 2019, 5:30 AM

#

You also need to understand what a function really is

#

a function, basically, gives you an output for something you input

#

for f(x)=x^2+2

#

x is your input

#

f(x) (also could be y) is your output

#

So what slope is telling you is the rate output/input

grim lava Nov 17, 2019, 5:32 AM

#

and that translates to the fact that a function can only have one output per input, in other words one x value can only give one y-value

gusty ermine Nov 17, 2019, 5:33 AM

#

x's cannot be repeated but y's can be?

grim lava Nov 17, 2019, 5:33 AM

#

yes

mossy cloud Nov 17, 2019, 5:33 AM

#

yes

grim lava Nov 17, 2019, 5:33 AM

#

well a function cannot have more than 1 y-value per x-value is what i think u meant, but the reverse can happen

#

like in a vertical parabola

gusty ermine Nov 17, 2019, 5:34 AM

#

vertical parabola like y=x^2?

grim lava Nov 17, 2019, 5:34 AM

#

yes

gusty ermine Nov 17, 2019, 5:34 AM

#

Wait but reverse wouldn't be a function

#

it it was x=y^2, that's not a function

mossy cloud Nov 17, 2019, 5:35 AM

#

Only half of it at a time would be a function

grim lava Nov 17, 2019, 5:36 AM

#

in other words, the positive square root and the negative square root would be functions separately but not together (because x = y^2 is the same as y = +- sqrt(x))

mossy cloud Nov 17, 2019, 5:36 AM

#

You could think of it like this: every input of a function has one and only one answer

#

If it had two, that'd be confusing

#

Which one do you use?

#

If we apply our knowledge of slopes to calculus

#

What do you think derivatives do? @gusty ermine

gusty ermine Nov 17, 2019, 5:38 AM

#

derivatives show the slopes of the graph

#

at a certain point?

mossy cloud Nov 17, 2019, 5:39 AM

#

@real imp btw, did you know that when Isaac Newton invented Newtonian mechanics, he invented calculus to describe it

#

Yeah, that's the gist of it, but it's not technically correct

grim lava Nov 17, 2019, 5:39 AM

#

yeah, thats correct, but only visually

#

conceptually no

mossy cloud Nov 17, 2019, 5:40 AM

When we took the slope before, we only took the average rate of change

Can you describe it?

gusty ermine Nov 17, 2019, 5:42 AM

#

limits is something like as you approach a point in x axis what is the y value of it

grim lava Nov 17, 2019, 5:42 AM

#

if its a non-horizontal line, then the derivative graphically becomes a horizontal line

mossy cloud Nov 17, 2019, 5:43 AM

#

That's a very special case of the limit panda

grim lava Nov 17, 2019, 5:43 AM

#

if its a horizontal line, it becomes a horizontal line at y=0

gusty ermine Nov 17, 2019, 5:43 AM

#

ooooo

#

you're so right

mossy cloud Nov 17, 2019, 5:44 AM

#

You can be more general. The limit is the value you get when you approach a specific number super super close

gusty ermine Nov 17, 2019, 5:44 AM

#

right

mossy cloud Nov 17, 2019, 5:44 AM

#

It never quite gets there, but it gets super close

#

So if you remember our slope

#

Imagine brining those two points super super close to each other

#

So much, that you get very close to the true tangent line

#

That's the instantaneous rate of change

#

and that change is dx

#

a super small "nudge" of a value x

#

dy/dx is the change in dy when you move a very small nudge dx

#

that's why I like Leibniz notation of derivatives more than the others

#

It's more intuitive

#

it's quite literally slope

gusty ermine Nov 17, 2019, 5:47 AM

#

what leibniz notation

#

is*

mossy cloud Nov 17, 2019, 5:47 AM

#

dy/dx vesus f'(x)

#

It's just that way of writing derivatives

#

I hate using "f prime, y prime"

#

i like math, its just that it is so time consuming and takes lots of time to understand it

mossy cloud Nov 17, 2019, 5:53 AM

#

My tip for you panda. When you learn a new concept, make a point of asking "Why?" Whether that'd be out loud to your teacher or to yourself, you'd be glad that you did. I spent a lot of time staring at something from my notes or just pacing around in my room thinking what the heck calculus really is, and it helps.

Anyone here with good with set theory / notation?

median trail Nov 17, 2019, 2:20 PM

#

you can leave it here and people will help you blobheart , I might help

marsh linden Nov 17, 2019, 2:36 PM

#

No nvm I think I worked it out haha

#

Wasn't sure what the difference was between max and argmax

#

If a=x ∧ b=y

means only true if a is equal to x and b is equal to y, yeah?

#

I just need to make sure that ∧ means what I think it means

median trail Nov 17, 2019, 2:46 PM

#

yes

marsh linden Nov 17, 2019, 2:49 PM

#

Aite

#

perfect

#

And do you know what the difference between R+ and R++ is?

With R i mean the set of all real numbers

#

I (think I) remember seeing both

#

but im not sure what the diff is

#

R+ is the set of all positive real numbers and R++ is ... ?

#

Is there a way of denoting subsets?

#

Like, If I have a set A

How would I define a subset for elements 1,2,...,s-1 and one s+1,s+2,...,N

Intenta traducirlo tú y después puedes ponerlo en #📝・correct-me-please @gusty ermine

gentle heath Nov 17, 2019, 3:33 PM

#

@marsh linden other than this one?

📎 M3SXo.png

marsh linden Nov 17, 2019, 3:33 PM

#

But how do I define the subset

#

A⊂B st. arg(elements of A)<s

#

im missing some notation

gentle heath Nov 17, 2019, 3:35 PM

#

arg = complex numbers arg?

marsh linden Nov 17, 2019, 3:35 PM

#

naa

#

naa forget args for the moment

#

not relevant yet haha 😅

#

Lets say I have a set A={a,b,c,...x,y,z}

How do I denote a subset of A that only includes the letters a to r?

#

Without writing out every element of the subset

gentle heath Nov 17, 2019, 3:36 PM

#

B = {x∈A:condition for subset} ⇔ B⊆A

#

hmm

marsh linden Nov 17, 2019, 3:37 PM

#

if a>b>c>d>...>z

gentle heath Nov 17, 2019, 3:37 PM

#

oh thats fine then

#

like this

#

B = {x∈A:a≤x≤r}

#

if they're ordered like that

marsh linden Nov 17, 2019, 3:38 PM

#

Ah nice

#

perfect

#

And there's no way to write it if I just want the first s elements?

#

Assuming they're not ordered

gentle heath Nov 17, 2019, 3:39 PM

#

depends on context really

#

sets aren't ordered

#

so no

#

but it can kinda work like that

#

{2,1,3}={1,2,3} in sets remember

#

so the first s elements doesnt really mean much

marsh linden Nov 17, 2019, 3:40 PM

#

ye but what im doing kinda applies set theory, it's not exactly set theory >_<

gentle heath Nov 17, 2019, 3:41 PM

#

like if the elements are ordered such that you can define a condition

#

sure

marsh linden Nov 17, 2019, 3:41 PM

#

Basically I have an auction with n>2 players, each with a valuation vi

They're ordered such that v1>v2>v3...>vn

#

So the order matters

#

thats why i was talking about arg before

#

bc argmax is important

#

in this case

gentle heath Nov 17, 2019, 3:42 PM

#

so you want the first however many highest bids

#

valuations

#

etc

marsh linden Nov 17, 2019, 3:42 PM

#

ye

gentle heath Nov 17, 2019, 3:43 PM

#

yeah you can define a condtion cos they're numbered in order

#

just do some thinking cos you know the full situation

#

but i mean set notations not exactly built for this

marsh linden Nov 17, 2019, 3:44 PM

#

ye

#

game theory takes it and kinda plays with it a little

gentle heath Nov 17, 2019, 3:45 PM

#

gotta love game theory

#

isn't that more suited for what u want?

marsh linden Nov 17, 2019, 3:45 PM

#

wdym

#

game theory is what im doing atm

gentle heath Nov 17, 2019, 3:46 PM

#

yeah I thought

#

so what you hunting for set notation for

#

use the game theory shit

marsh linden Nov 17, 2019, 3:46 PM

#

its basically the same

#

📎 unknown.png

#

But making sense of it can be pre rough

#

im not used to the notation tbh

gentle heath Nov 17, 2019, 3:48 PM

#

fuck me

#

not even gonna ask what the delta and u_i things are

marsh linden Nov 17, 2019, 3:51 PM

#

naa thats not even too bad haha

#

delta(Ai) is the set of all probability distr. across Ai and ui is a utility function for player i

gentle heath Nov 17, 2019, 3:52 PM

#

bruh

marsh linden Nov 17, 2019, 3:52 PM

#

but my teacher loves to add in shit that looks completely ridiculous

#

and then never ask about it

like

look at this, you'll probs like it idk

I don't have a cool enough name for these theorems

marsh linden Nov 17, 2019, 3:54 PM

Right?

gentle heath Nov 17, 2019, 3:54 PM

#

can't go into maths cos my names too boring

marsh linden Nov 17, 2019, 3:55 PM

yeah man

#

thats motivation right there

#

to discover some new theorem
