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...
A New Experimental Feature: scoped stylesheets
Chromium recently implemented a new feature from HTML5: scoped stylesheets, aka. <style scoped>. A web author can limit style rules to only apply to a part of a page by setting the ‘scoped’ attribute on a <style> element that is the direct child of the root element of the subtree you want the styles to be applied to. This limits the styles to affect just the element that is the parent of the <style> element and all of its descendants. Example Here’s a...
Be careful about printing error as string in GoLang
In GoLang, we can format and produce string using fmt.Printf(), just like C, GoLang also supports format verbs like %s, %d which can be placeholder for different types of values. But please pay attention when printing error as string so that you will not fall into some trap. Let's first take an example code snippet and see what trap we are talking about. package main import "fmt" type A string func (a A) Error() string { return fmt.Sprintf("%s is an error", a) } func main() { a := A("hello...

ByteBuffer in Java
ByteBuffer is introduced in java.nio since Java 1.4. It provides a way of representing raw structured data such as from a file or from network. It enables fast access of underlying data compared to traditional ways like byte[] Prior to Java 1.4, if you want to represent a structured raw data, you need to create a byte[] and then having a set of checks to delimit the byte array to get the expected tokens. There are three ways to create a ByteBuffer: Wrapping an exiting array by calling ByteBuffe...

A journey to investigate a goroutine leakage case
In Go, creating goroutines is straightforward, but improper usage may result in a large number of goroutines unable to terminate, leading to resource leakage and memory leaks over time. The key to avoiding goroutine leaks is to manage the lifecycle of goroutines properly. By exporting runtime metrics and utilizing pprof, one can detect and resolve goroutine leakage issues. This post will go through one real case encountered by the author. The author maintains a service that connects to a targe...

Hologres vs AWS Redshift
Hologres and Redshift are both data warehousing solutions, but they have some differences in terms of features, architecture, and target use cases. Underlying Infrastructure Hologres: Built on Alibaba Cloud's Apsara distributed computing platform, Hologres leverages the underlying infrastructure for storage, computation, and management. It benefits from Alibaba's expertise in cloud-native architecture and real-time data processing. Redshift: Amazon Redshift is based on a Massively Parallel Pro...

Why there is white/blank space instead of AdSense ad on my website?
Usually if you see on your website a white/blank space instead of Adsense ads, this means that Adsense cannot show adds in that unit for some reasons (we are going to talk about possible reasons below) and also you have enabled the “Fill space with a solid color†feature (in the “Choose what to display if no relevant ads are available†settings of this ad unit). I probably should also say that if you set “Show public service ads†instead of the “F...
Faster than C
Judging the performance of programming languages, usually C is called the leader, though Fortran is often faster. New programming languages commonly use C as their reference and they are really proud to be only so much slower than C. Few language designer try to beat C. What does it take for a language to be faster than C? Better Aliasing Information Aliasing describes the fact that two references might point to the same memory location. For example, consider the canonical memory copy: void...

Introducing LocalDB, an improved SQL Express
Updated 2011-11-28: Added reference to the walkthrough of using LocalDB in Visual Studio 2010 and to the new LocalDB Installer. Updated 2011-11-02: Added reference to .NET Framework 4 support for LocalDB in the Q&A section. Introduction It gives me great pleasure to introduce a new version of SQL Express called SQL Express LocalDB. LocalDB is created specifically for developers. It is very easy to install and requires no management, yet it offers the same T-SQL language, programming surfac...

Flash Player sandboxing is coming to Firefox
Peleus here. In December of 2010, I wrote a blog post describing the first steps towards sandboxing Flash Player within Google Chrome. In the blog, I stated that the Flash Player team would explore bringing sandboxing technology to other browsers. We then spent 2011 buried deep within Adobe laying the groundwork for several new security innovations. Today, Adobe has launched a public beta of our new Flash Player sandbox (aka “Protected Modeâ€) for the Firefox browser....
