Banana Pi M5 Pro Quick Review

My old ODROID-U3 has been giving me quite some headaches. Its old USB 2.0 ports and 100Mbps Ethernet port are also very limiting in 2023. Its power supply is not the best (not an uncommon issue with HardKernel’s products, certainly not uncommon among the older generation of single board computers). A hardware upgrade is therefore necessary.

I don’t really use it for anything else other than a humble home server to stream videos, music, and sometimes photos. Generally used as a private file share system at home. I already bought an 1 TB USB 3.0 HDD, so I definitely need a device that supports USB 3.0 at least. To not have a limiting network I/O, it should also have 1Gbps Ethernet port.

Why not buying a popular Raspberry Pi 4? Well, I tried, but it’s out of stock everywhere. That’s why I turned to its alternatives, initially I was going to buy another HardKernel’s ODROID product, but its pricing in Europe is just way too high than the price on its website. Unfortunately, (not sure if this has anything to do with Brexit), there is a minimum order requirement to ship to the UK. I’m building a cluster or something, so looking again…

Ta-da! I found Banana Pi, the name is a bit.. knock-off, and the manufacturer is in China, I’ll let you connect the dots. Banana Pi M5 is not the newest model, but it’s comparable to Raspberry Pi 4 and ticks all of my boxes. Long story short, I bought it from Ali-Express where it’s much cheaper than Amazon or other local retailers here. They were also running some sales on bundles, so I ended up buying it with a metal case, yet paying less.

On paper, it provides even better performance than Raspberry Pi 4! More importantly, it’s readily available! One thing I did pay extra attention to is the availability of upstream Linux images, having suffered quite a bit there with HardKernel’s products. Thankfully, Banana Pi has Armbian support (rated platinum for Banana Pi M5, whatever platinum means). To save even few more pennies, it comes with an onboard 16GB eMMC storage!

It’s been faithfully serving its purpose on the shelf next to the router for a couple of weeks now. Reliable little machine that’s fast and responsive! If you’re thinking of buying a single-board computer like Raspberry Pi, but couldn’t find available stocks, Banana Pi might fit in.

A New Termux Mirror

TL; DR. is a new Termux packages mirror! Maintained by me, synchronised every six hours, located in the United Kingdom, hosted by Oracle Cloud.

In the full article below, I’ll write up how to set up a Termux mirror (or in general, a Debian packages repository mirror).

Virtual Linux Desktop Experience in Azure

I wouldn’t believe that I will be writing this 10 years ago. It’s 2020 though. Microsoft has improved a lot of services for Linux, ranging from developer tools like Visual Studio Code, to the protagonist today: Azure (cloud computing). Azure has steadfastly become a real credible alternative to Amazon EC2 (or AWS in general). Today, I want to share my experience of using a virtual machine on Microsoft Azure cloud. To be more specific, it is a Linux desktop virtual machine (SLES 15).

pm = dynamic#默认
pm.max_children = 6#平均一个php-fpm子进程占用内存5~10MB,发生内存泄漏时可能占用20M,对于128M内存的VPS,访问量也不大,6个够了
pm.start_servers = 1#小内存VPS启动1个子进程没商量
pm.min_spare_servers = 1#最少闲置子进程1个
pm.max_spare_servers = 3#最多闲置子进程3个
pm.max_requests = 1000#子进程访问量达到1000次后重生,以防止第三方模块/程序内存泄漏的影响
