The cryptocurrency landscape today is a little bit of a maze. There seem to be countless cryptos available — thousands of them, by some estimates — and unless you’re particularly well versed in this technology, it can be difficult to tell what differentiates them.To cut through some of the confusion, we decided to take a closer look at cryptocurrencies. We won’t simply list the most prominent ones, the way so many sites already have. Instead, we’re going to look into what makes a cryptocurrency successful, so that you might learn to gauge the constant new addition...

TikTok confirmed on Saturday to sue US government and US president Donald Trump over Trump administration's executive order on potentially banning TikTok in US.This Chinese short video app is the most downloaded app on App Store and PlayStore over past few months and has gained extremely high popularity among American youths. The parent company ByteDance claimed that the government's ban is illegal and hurts the interests of America people."Even though we strongly disagree with the administration's concerns, for nearly a year we have sought to engage in good faith to provide a constructive sol...

Today, there are many tools that developers can use to create an API, meaning that some of them can come up with an API within a matter of minutes. However, there is a vast difference between just creating an API and building one that meets all your expectations, is reliable and secure. Some developers create APIs that work well but forget some basic things that, within no time, bring a lot of issues to the API users. In this article, we are going to talk about the basic mistakes that developers make when creating APIs.Image Source: https://www.pexels.com/photo/photography-of-person-typing-118...

As a developer, there might be some need to fake locations when developing and testing mobile apps for different countries. Lots of the times some fake GPS apps will be used and they will ask to enable mock location access on the device before allowing you to fake GPS. To achieve this, we first need to have developer mode enabled.In this post, we will show how the developer mode can be enabled and disabled on Huawei devices.Go to Settings, find About phone and open it. You should be able to see an entry called Build number. Tap on that 5 - 7 times.You will see either one of below depends on yo...

In C programming, if using return in main function, the whole process will terminate. To only let main thread gone, and keep other threads live, you can use thrd_exit in main function. Check following code:#include #include #include intprint_thread(void *s){ thrd_detach(thrd_current()); for (size_t i = 0; i < 5; i++) { sleep(1); printf("i=%zu\n", i); } thrd_exit(0);}intmain(void){ thrd_t tid; if (thrd_success != thrd_create(&tid, print_thread, NULL)) { fprintf(stderr, "Create thread err...

Sometimes when handling a long running process, there would be need to track the progress so that people know something is still running instead of doubting something goes wrong. In this case, a progress bar which indicates the current status and progress would be desired.This post will show an example on how to implement progress bar using GoLang. Let's take a look at the final outcome first before jumping into the implementation detail.The key in the implementation is actually just the \r control flag for fmt.Printf(). \r is actually the carriage return control which tells the cursor to move...

Linux kernel is in the process of replacing the HTTP links in its source code with HTTPS links. HTTPS is considered more secure than HTTP and can prevent lots of attacks like Man-In-The-Middle attack. Currently there are more than 150 patches submitted by Linux Kernel developers to replace these HTTP links. One thing to be noted is this replacement process is not a manual search and replace process. Indeed, some scripts are created to find out these links and try to find whether there is corresponding HTTPS link available and then do the replacement only if the HTTPS link works....

In our daily work, there might be need to run some important program for hours or even days without being abruptly terminated. In such case, we may want to run the program with command nohup.nohup is the abbreviation of no hangup, i.e, don't hang up or terminate the process. This command will tell the process to ignore the system HUP signal. The HUP signal will be emitted when the terminal is exited or disconnected. Normally process will abort its execution when receiving this signal. Basic SyntaxThe basic syntax for nohup isnohup command argumentsornohup optionsIf you want to know more u...
