I’m excited to share a set of mobile apps I’ve recently completed and published on both the Google Play Store and the Apple App Store. These apps are designed with a simple goal in mind: to make meaningful, structured content more accessible, whether you’re studying theology or improving your English vocabulary. 📱 Now Available on Both Platforms All apps are live and available for download: Google Play Developer Page: https://play.google.com/store/apps/dev?id=5835943159853189043 Apple App Store Developer Page: https://apps.apple.com/ca/developer/q-z-l-corp/id1888794100 📖 Theology & Confession Study Apps For those interested in Reformed theology and classical Christian teachings, I’ve developed a series of apps that present foundational texts in a clean, focused reading format: The Belgic Confession Canons of Dort Heidelberg Catechism Westminster Shorter Catechism Each app is designed to provide a distraction-free experience, making it easier to read, reflect, and revisit these im...

change password to any you like 


10.140.0.4 is your internal ip, you can get it via ifconfig 




ifconfig 
ens4      Link encap:Ethernet  HWaddr 42:01:0a:8c:00:04  
          inet addr:10.140.0.4  Bcast:10.140.0.4  Mask:255.255.255.255


 


by the way, please remember set a new firewall rule for 4444 port.


or you can set a rule like, tcp:0-65535,  udp:0-65535






 



Install bbr to accelerate tcp  


wget –no-check-certificate https://github.com/teddysun/across/raw/master/bbr.sh  
chmod a+x bbr.sh 
sudo ./bbr.sh


sysctl net.ipv4.tcp_available_congestion_control


 





Clients guide, please refer to


https://shadowsocks.org/en/download/clients.html 



The server IP is your external static IP.

  Today is January 1st, 2026 .  Before rushing into new goals, I spent some time looking back at the past 12 months of data for this blog — the quiet numbers that tell a very honest story.  Looking Back at the Numbers  Over the past year:    📈 Total views:  ~44,600    👀 Daily average visits:  ~200    💬 Comments:  19    💰 AdSense income:  about $0.01 per month    At first glance, these numbers may look small — especially the income. But when I zoom out, I see something more meaningful.  This blog has been quietly read every single day .  No viral posts.  No aggressive promotion.  No paid traffic.  Just consistent readers arriving through search, bookmarks, and curiosity.  That consistency matters.  What the Traffic Graph Tells Me  The graph over the last 12 months shows something important:    Early months were quiet and uneven    Mid-year brought steady growth    Toward the end of the year, traffic became more stable , with clear spikes when certain posts resonated    This tell...

Health Checks and Scaling Strategies for Next.js in Kubernetes    This is Part 6  and the final post of the series: Self-Hosting Next.js in Kubernetes (Without Vercel) .    At this point, your Next.js standalone app:      Builds cleanly    Runs in a minimal Docker image    Deploys correctly on Kubernetes / OpenShift    Serves static assets properly    Uses runtime configuration and secrets     Now let’s make it resilient and scalable .     Why Health Checks Matter    Kubernetes relies on health checks to:      Know when a pod is ready to receive traffic    Restart unhealthy containers    Safely roll out new versions     Without proper probes, traffic can be sent to a pod that isn’t ready yet.     Readiness Probe    A readiness probe tells Kubernetes: “This pod can accept traffic.”     For most Next.js apps, the root path works well:   readinessProbe:   httpGet:     path: /     port: 3000   initialDelaySeconds: 10   periodSeconds: 5    If your app depends on downstream services (APIs, d...
