Stevey's Google Platforms Rant

I was at Amazon for about six and a half years, and now I've been at Google for that long. One thing that struck me immediately about the two companies -- an impression that has been reinforced almost daily -- is that Amazon does everything wrong, and Google does everything right. Sure, it's a sweeping generalization, but a surprisingly accurate one. It's pretty crazy. There are probably a hundred or even two hundred different ways you can compare the two companies, and Google is superior in all but three of them, if I recall correctly. I actually did a spreadsheet at one point but Legal wouldn't let me show it to anyone, even though recruiting loved it.

I mean, just to give you a very brief taste: Amazon's recruiting process is fundamentally flawed by having teams hire for themselves, so their hiring bar is incredibly inconsistent across teams, despite various efforts they've made to level it out. And their operations are a mess; they don't real

Setting up iOS Universal Links

Take the download.sh file and put it into a directory where you want the files to be saved.
cd into the directory and make sure that it has executable permissions (chmod +x download.sh should do it)
Run ./download.sh and wee there it goes. Also if you do not want all the files, just simply comment the ones you do not want.

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.

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

	* Allows you to subscribe to some event
	* sub1 = emitter.subscribe('function_name', callback1);

	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
