  trim() in JavaScript

In the past, JavaScript didn't define the trim() function for String object. This makes web programmers frustrated since they often need to implement this function themselves if they want to handle user inputs. The new version of ECMA-262 introduces the trim() function.15.5.4.20   String.prototype.trim ( )     The following steps are taken:     1.   Call CheckObjectCoercible passing the this value as its argument.   2.   Let S...

  Efficiency of code execution

If you want to optimize your program codes, you need to find their Hotspot, i.e, the codes which are executed most frequently. If you can optimize this portion of codes a bit, you may gain much improvement of your code efficiency. Here I give you three examples about efficiency of code execution.1. PHP's Getter and Setter (From Reddit)This example a quite simple, you can skip it if you want.Consider the code below, we can find it's slower when we use Getter/Setter method to read a member variabl...

  Multithreading interview questions in Java

Multithreading as a widespread programming and execution model allows multiple threads to exist within the context of a single process. These threads share the process' resources but are able to execute independently. The threaded programming model provides developers with a useful abstraction of concurrent execution. However, perhaps the most interesting application of the technology is when it is applied to a single process to enable parallel execution on a multiprocessor system.Many programme...

  Top 10 reasons to use a low-code platform

Generally, as the best coding platforms, low code includes low code app development, process development solutions and software development tools. IT users utilize low code solutions as a source of the required building blocks for the building of workflows and applications. The building blocks make it easier to assemble apps and workflows without requiring hand-coding. The growth of low-code platforms therefore levels business grounds by reducing the time spent in coding among other benefits.&nb...

  First Chinese app on Google Glass : PM25.in

PM25.in is an open source PM2.5 project developed by BestApp. It retrieves PM2.5 data of different cities in China through a crawler and then processes the data retrieved. They also created an API which enables third parties to access these data. Now the team has built something new, they moved this project to Google Glass and developed the world's first Chinese Google Glass application -- PM25.in. Now users with Google Glass can check PM2.5 of different cities in China. The final effect on Goog...

  Applying Large Language Models (LLMs) to Solve Cybersecurity Questions

In this document, we will introduce some test, experiment and analysis conclusion about applying Large Language Models (LLMs) to solve cybersecurity questions. Introduction Large Language Models (LLMs) are increasingly used in education and research for tasks such as analyzing program code error logs, help summarize papers and improving reports. In this project, we aim to evaluate the effectiveness of LLMs in solving cybersecurity-related questions, such as Capture The Flag (CTF) challenges, ...

  Some tricks on PHP session

1. Session timeout problem There is a nuance we found with session timing out although the user is still active in the session.  The problem has to do with never modifying the session variable. The GC will clear the session data files based on their last modification time.  Thus if you never modify the session, you simply read from it, then the GC will eventually clean up. To prevent this you need to ensure that your session is modified within the GC delete time.  You can accomp...
