Day 1 and Day 2(Math's & Programming Language):
So to solve any type of Coding problem, you should know basic Mathematics🧮 for the first 2 days.
If you are already aware of the basic math concepts you should spend this time selecting your own Programming Language.

A low #CPI triggered a 114-point jump that took it above the dominant trendline. At the open, sell orders above that level initiated a pullback that took it 126 points down to the 20DMA
Not what we would call a 1-day reversal, more upside to come

1 representa tierra, y 0 el mar.
Una isla esta representada por varios 1 contiguos.
Cuántas islas hay en los arrays que nos den?

De esta forma, para poder llegar a cualquier caja, tendremos que empezar desde la primera, e ir leyendo cada post-it hasta encontrar la que necesitemos.
Cada caja solo sabe su contenido y donde está la siguiente caja (y la anterior en el caso de una lista doblemente ligada)

Mmm, se me ocurre usar:
- indexOf
- filter
- includes
- incluso un for común y corriente.
El problema de todas estas soluciones, es que tienen un costo en Big O lineal. Big O(n), donde n es el tamaño de la lista.
Podemos hacerlo mucho mejor!

La semana pasada hablamos de #debounce. #throttle es una función hermana de esta.
Throttle es una función que recibe 2 args: la función a ejecutar y un tiempo de bloqueo.
Cuando la función se ejecuta, el tiempo comienza a correr y bloquea cualquier otra ejecución.

Veamos el problema!
Tenemos una función que imprime texto en la consola.
El entrevistador solamente dirá: "ok, programa un throttle"
Si no sabes que es un throttle, te lo explicará. Pero son puntos menos, cuidado! 🚨
Throttle y debounce son tools básicas para todo frontend.

Here goes my @threadapalooza on Heidegger, the greatest thinker of the modern era, a social, political, and cultural conservative (who briefly flirted with fascism and Nazism), a mystic, a contemplative, a contrarian, and a thinker whose influence extends far beyond academia...
What was Heidegger's main thesis?
He's hard to pin down & scholars fight about what it means to be "Heideggerian." But Heidegger himself said that his best readers should not be Heideggerian, i.e., followers, but should instead take up his thought in their own original way. 2/

Being a Heideggerian is a performative contradiction--follow Heidegger or reduce him to a thesis and you've missed the forest for the trees. To write about Heidegger as an academic is to be at odds with Heidegger's spirit. 3/

2. Behavioral and cultural screen with @Latesha_Byrd
3. Deep dive on department domain and current tools and techniques
Technical preparation included practicing @LeetCode and @CodeSignalCom for #SQL and #python. I started to time myself and also spoke out loud what I was doing and why to get familiar with #whiteboarding etiquette. I also had my friends mock interview me.
I also utilized @TeamBatcode for more #python practice with primitive #datastructures and #Algorithms. It was consistent practice while talking out loud. I probably worked through about 50-60 problems.

This is the time in the market's rally when FOMO replaces FEAR and when the confident "talking heads" who projected a market retest are equally confident that a new bull market leg is upon us.
To me, this is the time in the market's rally to reassess
upside reward vs downside risk in all of your holdings (hint: it is deteriorating) - as many equities are up substantially from the third week of March.
It is the time to also consider margin of safety in your holdings.
Just as it was, with the benefit of hindsight, appropriate
