Web in October - Newsletter by Agney

Hey November 🪔

Facebook and it’s companies, Instagram and Whatsapp went down for hours straight this month. It got trending everywhere and even drove the installs up for competing products. In countries where Whatsapp is the main app for communication, people resorted to text messaging.

From the facebook explanation post:

This was the source of yesterday’s outage. During one of these routine maintenance jobs, a command was issued with the intention to assess the availability of global backbone capacity, which unintentionally took down all the connections in our backbone network, effectively disconnecting Facebook data centers globally. Our systems are designed to audit commands like these to prevent mistakes like this, but a bug in that audit tool prevented it from properly stopping the command.

In the Spotlight 🔦

Most of the larger companies have resumes coming in at a very huge rate and getting all of them manually reviewed is an impossible task (or may be just one that the company does not want to invest in) Instead there would be machine learning systems that read off the tags on PDF and look for certain keywords (machine learning is a keyword in here, many a time these systems are just search and find)

This means, mostly all your resume needs are keywords, any creativity you try to pitch in there is useless.

CORS

CORS is arguably the most common security error that a frontend developer can run across. But even then it’s mysterious as to why and how it works, mostly the developer would change a header or install an extension and it would just work™️. But how does CORS help the web and why is it there?
