  How long does the heuristic cache of the browser actually cache?

Heuristic cache Heuristic caching is the default behavior of browser caching (i.e., for responses without Cache-Control), which is not simply "not caching", but implicitly caching based on the so-called "heuristic cache". HTTP is designed to cache as much as possible, so even if Cache-Control is not specified, the response will be stored and reused if certain conditions are met. This is called heuristic caching. HTTP/1.1 200 OK Content-Type: text/html Content-Length: 1024 Date: Tue, 22 Feb 2022 ...

  A Different Kind of Technical Interview

Everyone who's been programming professionally for a while knows the standard format of the technical interview. You go in, there's a whiteboard in the room, and you write code on it to answer questions.Everyone also has the same basic complaints about these interviews. In a normal work environment, you have access to an API or search engine, but at a whiteboard you don't. Whiteboard questions generally don't include much in the way of overall design, and they're typically limited to simple algo...

  Why Javascript is a Joy

I’m probably a bit biased – being a front-end web developer for a few years will do that – but I really enjoy writing Javascript. I’ve recently retreated from pure coding the last few months, but I got an opportunity this past week to jump back into some tasks, and it has reminded me how fun it is to dive into our[1] front-end codebase. Yes, Javascript can be surprisingly elegant yet completely infuriating, and all on the same line of code; for a long time, ...

  Cracks in the Foundation

PHP has been around for a long time, and it’s starting to show its age. From top to bottom, the language has creaky joints. I’ve decided to take a look at how things got to this point, and what can be (and is being) done about it. I start out pretty gloomy, but bear with me; I promise it gets better. In the Beginning, There Was Apache and CGI And there was much rejoicing. In 1994, Rasmus Lerdorf created the “Personal Home Page Tools,” a set of CGI binaries wri...

  Get hostname from a URL using JavaScript

Sometimes we may have strings which contain some UR;s and we may want to retrieve the hostname from the URLs for some statistic use. For example, we may have a URL : http://www.example.com/aboutus.html. We may want to retrieve the www.example.com from the URL. How? Use regular expression. Here I give an example using JavaScript. If you want to check whether a string is a URL or not. Refer to Detect URLs in a Block of Text. In JavaScript, we can have a regular expression like var pattern=/(.+:\/\...

  9 quotes that stayed with me as a developer

I find quotes inspiring, motivating or sometimes just thought provoking, so here's some of my favourites from over the years. Sometimes reading a book can have a real influence on how you write code, or how you approach a problem. Sometimes a simple quote  is enough to make me question the way I look at the code I'm writing. Or often I sit in awe about someone's so well distilled what I've known internally for ages but have never been able to enunciate.   "Design is finding t...

  Mount DD image on Linux

Yesterday, my Raspberry Pi running Arch Linux was not able to boot with error: Kernel Panic, not syncing: no init found. I spent a night on it, but could not find a working solution. The last option is easy: reinstall the system. That is really the last resort, for I do not want to re-setup everything I have done: samba server, Time Machine server, Xunlei Offline Downloader… Unable to mount the SD card The system does not boot, so I need to find a way to get into the file system to identi...

  How to enable developer mode on Huawei

Go to Settings, find About phone and open it. You should be able to se...

  Send email using PHPMailer on GoDaddy hosting

According to PHPMailer troubleshooting guide, GoDaddy has a very strict rule on sending email using PHPMailer. Popular US hosting provider GoDaddy imposes very strict (to the point of becoming almost useless) constraints on sending an email. They block outbound SMTP to ports 25, 465 and 587 to all servers except their own. This problem is the subject of many frustrating questions on Stack Overflow. If you find your script works on your local machine, but not when you upload it to GoDaddy, ...
