Constant confusion: why I still use JavaScript function statements

I’ve read this article that explains the comparison of declaring functions in javascript (ES2015 and above), with the short notation for a function. By Bill Sourour.

Cites the temporal dead zone (TDZ):

[…] JavaScript binds the declaration of “sayHelloTo” — reads it first, puts it at the top, and creates a space in memory to hold its value — but it doesn’t set “sayHelloTo” to anything until it reaches it during execution.

The time between “sayHelloTo” being bound and “sayHelloTo” being initialized is called the temporal dead zone (TDZ).

I attended a workshop on AWS Kinesis, called AWS Kinesis Zombieland by Javi Moreno at capside.

Notes

AWS Kinesis Zombieland

• muy importante escoger bien la clave de particionado (id de shard)
• KPL librería de kinesis que te permite hacer batching, timeout, …
  • la otra se llama KCL.
  • KCL permite mantener estado
• cuando te pidan una app de big data, pregunta para qué lo quieren, lo mismo que con cualquier proyecto de software
• latitud = Y, longitud = x
• el canal se llama stream, la capacidad se llama shard
  • el shard sólo permite 5 lecturas por segundo, 2MB/s
• usar el shard como buffer
• usar la clave de particionado como algoritmo de agregación
• cada vez que tienes una tabla en dynamodb, tienes que poner una alerta de throughput
• nota: lo que no puedes hacer es guardarlos todos y luego procesarlo. no tienes potencia para todo eso

Preguntas:

• ¿cómo se calcula el id del shard?

How Agile Principles Can Fund Your Start-Up

I’ve read this article by Jurgen Appelo explaining how the agile values can help you negotiate funding for your startup: instead of negotiating with each investor, agree on a formula and invest in many small rounds, instead of a big one. This works both ways: for buying and for selling.

Suggests using a base plus the amount of sales in the last year * a percentage.

Books that have entered the queue:

In Release It!, terms related to stability:

• transaction: is an abstract unit of work processed by the system
• mixed workload: is a combination of different transaction types processed by a system.
• system: the complete, interdependent set of hardware, applications, and services required to process transactions for users
• stability: resilient system keeps processing transactions, even when there are transient impulses, persistent stresses, or component failures disrupting normal processing
• stress (to the system): is a force applied to the system over an extended period.
• impulse: is a rapid shock to the system.
• a material changes shape when stress is applied. This change in shape is called the strain.
• The original trigger and the way the crack spreads to the rest of the system, together with the result of the damage, failure mode.
• crumple zones: areas designed to protect passengers by failing first. called crackstoppers

All of these are quotes from the book.
