🔰 HOW TO PROTECT YOUR CAMERA FROM BEING HACKED AND YOURSELF FROM WEBCAM SPYING 🔰

1. ENABLE FIREWALL

A firewall protects your system by monitoring the network traffic and blocking suspicious connections. Make sure your computer’s inbuilt firewall is up and running. Many people ignore this step confidently.

2. USE A TRUSTED AND RELIABLE ANTI-VIRUS

Choose one with advanced protection against malware, spyware, and viruses. An antivirus program will take care of detecting and will kick out malicious threats before they do any harm.



3. CHECK THE CAMERA ACCESS

So many apps require access to your camera and we always allow without thinking twice just like we do with terms and conditions. Well from now on be careful with it. If an unrequired app is asking for camera access then deny it.

4. BEWARE OF PHISHING TRAPS

We already have told you about phishing in many previous posts. But for those who are new, Phishing is a type of online scam where criminals create a link to get access to your account or device if you opened that link.

5. BE CAREFUL IN PUBLIC WI-FI

Public Wi-Fi networks are extremely vulnerable to cyber attacking. Many cybercriminals are looking for prey who are using public wi-fi and try to put malware on their device. Use VPN while using public wi-fi.

6. COVER YOUR WEBCAM AND MIC

Yes, that’s right. Even Mark Zuckerberg does it. It’s the easiest and 100% reliable way to prevent someone from watching you through your computer camera.

American technology startup accelerator Y Combinator has sent out a note to its alumni network of startups warning them of the coming economic downturn, and the funding consequences that may effect even the top startups.

"If your plan is to raise money in the next 6-12 months, you might be raising at the peak of the downturn. Remember that your chances of success are extremely low even if your company is doing well... We recommend you change your plan," the note added.

What's good to hear in answer and what raises red flag:

1. Can you name two programming paradigms important for JavaScript app developers?

JavaScript is a multi-paradigm language, supporting imperative/procedural programming along with OOP (Object-Oriented Programming) and functional programming. JavaScript supports OOP with prototypal inheritance.

Good to hear:

Prototypal inheritance (also: prototypes, OLOO).
Functional programming (also: closures, first class functions, lambdas).

Red flags:

No clue what a paradigm is, no mention of prototypal oo or functional programming.

#javascript #js
2. What is functional programming?

Functional programming produces programs by composing mathematical functions and avoids shared state & mutable data. Lisp (specified in 1958) was among the first languages to support functional programming, and was heavily inspired by lambda calculus. Lisp and many Lisp family languages are still in common use today.

Functional programming is an essential concept in JavaScript (one of the two pillars of JavaScript). Several common functional utilities were added to JavaScript in ES5.

Good to hear:

🔹 Pure functions / function purity.
🔹 Avoid side-effects.
🔹 Simple function composition.
🔹 Examples of functional languages: Lisp, ML, Haskell, Erlang, Clojure, Elm, F Sharp, OCaml, etc…
🔹 Mention of features that support FP: first-class functions, higher order functions, functions as arguments/values.

Red flags:

🔻 No mention of pure functions / avoiding side-effects.
🔻 Unable to provide examples of functional programming languages.
🔻 Unable to identify the features of JavaScript that enable FP.
