He sido freelance, emprendedor y trabajo desde hace años para empresas USA de diversos tamaños en remoto como programador fullstack. Ahora en GitHub. Si puedo ayudar a alguien en orientar su carrera, mis DMs están abiertos. Ask me anything.

he recibido muchos mensajes y escribo aquí algunos de los consejos que he dado en resumen. Nota: algunas cosas son concretas de trabajar en España. Si vas a trabajar desde Sudamérica sólo una nota: tienes la ventaja de la zona horaria para trabajar con EEUU.

Inglés

Tener un buen nivel de inglés es fundamental para poder trabajar con clientes extranjeros. El conocimiento del idioma tiene que mantenerse en el tiempo. Es como mantenerse en forma física; si lo dejas, lo pierdes. Personalmente aunque trabajo 100% en inglés desde hace bastantes años, intento crearme un entorno diario con el idioma para no perderlo:

WannaCry|WannaDecrypt0r NSA-Cyberweapon-Powered Ransomware Worm

Virus Name: WannaCrypt, WannaCry, WanaCrypt0r, WCrypt, WCRY
Vector: All Windows versions before Windows 10 are vulnerable if not patched for MS-17-010. It uses EternalBlue MS17-010 to propagate.
Ransom: between $300 to $600. There is code to 'rm' (delete) files in the virus. Seems to reset if the virus crashes.
Backdooring: The worm loops through every RDP session on a system to run the ransomware as that user. It also installs the DOUBLEPULSAR backdoor. It corrupts shadow volumes to make recovery harder. (source: malwarebytes)
Kill switch: If the website www.iuqerfsodp9ifjaposdfjhgosurijfaewrwergwea.com is up the virus exits instead of infecting the host. (source: malwarebytes). This domain has been sinkholed, stopping the spread of the worm. Will not work if proxied (source).

update: A minor variant of the viru

FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.

	GraphQL at massive scale
	- IBM cloud = node micro services (30+ teams) - separate codebases
	- frontend need to fetch data from multiple endpoints (bad documentation) - it’s a inconsistent mess
	- graphql centralize this - grapnel microservice (single endpoint), documentation included
	- data sources (schema + resolvers + model + connector) = plugin (independent GitHub repo)
	- GrAMPS Middleware (schema stitching)
	- extended error messages (GUID, documentation links
	- datasource starter kit (strong starting point for new data sources)
	- GitHub: grapms-graphql/gramps-express (based on Apollo server) - MIT licence - GraphQL Apollo Microservice Patterns Server

	* Create an event emitter that goes like this
	* emitter = new Emitter();
	*
	* Allows you to subscribe to some event
	* sub1 = emitter.subscribe('function_name', callback1);
	* (you can have multiple callbacks to the same event)
