PHP Multithreading – Faking It
PHP doesn’t really support multi-threading per se but there are ways to do “fake†multithreading. Here’s one I saw in the PHPClasses.org newsletter – Multi-thread Simulation. Note that this class is intedend for use on a webserver, as opposed to running PHP scripts from a command line (or similar). Check the end of this post for some alternatives you can try if you’re using PHP as a stand-alone scripting language. Now, I’m going to be lazy and just ...

File upload once again
File upload is one of the oldest operation of web design. After 20 years, it's still has no big change, difficult to handle, lack of interaction and poor user experience. Web developers have thought many methods to improve the experience of uploading file in web apps, they developed various plugins based on different JavaScript libraries. However, because of the difference among different web browsers, there is no common interface which makes these plugins work properly or easily on all web brow...

Install Google services on Huawei MatePad
Since the trade war between China and US, lots of services are not allowed to be used on Huawei devices as a series of procedures enforced by US government to restrict China. These services include the Google Play services which are used for downloading Android apps on Android devices. This has brought big trouble to Huawei users as they are not able to download apps available for all other Android devices. Fortunately, there are ways for people to get Google services installed on Huawei d...

When to use STDERR instead of STDOUT
Every process is initialized with three open file descriptors, stdin, stdout, and stderr. stdin is an abstraction for accepting input (from the keyboard or from pipes) and stdout is an abstraction for giving output (to a file, to a pipe, to a console). That's a very simplified explanation but true nonetheless. Those three file descriptors are collectively called 'The Standard Streams'. Where does stderr come from? It's fairly straightforward to understand why stdin and stdout exist, however ...

Differences among Enter,F5 and Ctrl+F5 in webpage refresh
When we press Enter, F5 or Ctrl+F5 to refresh a webpage, is there any difference among them? Actually it's yes, we can find the difference from the request header and response header information. There are two cases about pressing Enter in the address bar. First if the page requested is cached and not expired in the browser, we can find the header information sent by the browser is : Host 192.168.3.174:8080 User-Agent Mozilla/5.0 (Windows NT 5.1; rv:5.0) Gecko/20100101 Firefox/5.0 Accept ...

What should a ‘cache’ be? It means a lot of things, but to my mind the default programming type should be: “keep around expensive-to-generate bits of read-only data in case we need them again, or until the computer really needs that RAM for something else†I was writing a custom video editing program in Python (interesting choice of language for that problem) and I wanted to cache decoded frames; but I just wasn’t happy with the memory management of explici...

Using C for a specialized data store
Pixenomics stores and transports 1.2 million pixels from the server to the client. During development we played with various methods to store and process this. Our ultimate goal was to send the entire board in under 1 second. During the stages of prototyping we used a MySQL database without thinking too much about performance. With a mere 2,000 pixels we quickly realised this wasn’t even usable as a demo. Changing the storage engine to memory was much better but still obviously unu...

Guide to Clearing Storage Space on a Macbook
Macbooks are pretty notorious when it comes to what storage space you have available. Those few gigabytes that you have will disappear in no time if you are not careful. The whole issue becomes even more problematic for people who are not that familiar with Macbooks or have switched from another computer. And if you do not pay attention, it will not take too long before you have next to no storage space on the hard drive. Leaving only a few gigabytes of free space will significantly reduce the ...
