  Chrome extension manifest v2 migration to v3

In 2023, Google would not allow Chrome extensions with manifest version before v3 to be listed on Chrome web stores as v3 extensions add more security privacy related restrictions on some of the functions. Hence all extensions with manifest v2 must migrate to v3. In this post, we would show how we did the migration for one of our extensions and the changes made. There is a checklist provided by Chrome team on what needs to be updated so that the extension can still work in v3. It can be checked ...

  Can private method be overridden?

The private methods are not inherited by subclasses and you cannot be overridden by subclasses. According to Java Language Specification (8.4.8.3 Requirements in Overriding and Hiding), "Note that a private method cannot be hidden or overridden in the technical sense of those terms. This means that a subclass can declare a method with the same signature as a private method in one of its superclasses, and there is no requirement that the return type or throws&nb...

  Google plans to deprecate FTP URL support in Chrome

Currently people can access FTP list and download resources hosted on FTP servers in Chrome through FTP URLs, but this may not work anymore in the near future. In a post published by Chrome engineers, there is a plan to deprecate FTP support in Chrome version 82. The major motivation for this deprecation is that Chrome doesn't have an encrypted FTP connection support(FTPs), this raises security risk of downloading resources over FTP. Since users can access FTP URLs and download resources, there...

  Leaving comments in real life

As a programmer I like to write comments because I know that some future person (often me) is going to need to know something about my code that won't be immediately obvious from reading it. Here's a recent example from my homebrew display's code:// protocol_init: Set up a newly powered-on string of lights.  The lights are arranged// in an array wired diagonally starting from the bottom left.  For ease of programming// it's better if they are given numbers which correspond to coor...

  Google Dart? Don’t bet against JavaScript

Procotols, programming languages and operating systems all compete in a constantly evolving software ecosystem. Out of that ecosystem only a few technologies truly have staying power and survive over the long term. An example? How about Ethernet? It’s been a survivor over the last thirty years despite existing in a constantly changing landscape that’s been populated with many worthy competitors. Ethernetâ€â„...

  Why Dynamic Programming Languages Are Slow

In a statically typed language, the compiler knows the data-type of a variable and how to represent that. In a dynamically-typed language, it has to keep flag describing the actual type of the value of the variable, and the program has to perform a data-dependent branch on that value each time it manipulates a variable.  It also has to look up all methods and operators on it. The knock-on effect of this on branching and data locality is lethal to general purpose runtime performance. T...

  A boolean value interview question

Someone asked a question on StackOverflow, he was asked an interview question. The question is : Given 3 boolean variables a, b, c, return true if at least 2 out of the 3 are true. He gave the solution as follows :boolean atLeastTwo(boolean a, boolean b, boolean c) {    if ((a && b) || (b && c) || (a && c)) {        return true;    } else {        ret...

  RAM is the new disk...

Jim Gray, a man who has contributed greatly to technology over the past 40 years, is credited with saying that memory is the new disk and disk is the new tape. With the proliferation of "real-time" web applications and systems that require massive scalability, how are hardware and software relating to this meme? Tim Bray, in his discussions about grid computing before it became such a hot topic, pointed out how advances in hardware around RAM and networking were allowing for the creation...
