ciaovietnam — Thu, 02 Oct 2025 08:09:21 +0000

I've been building this CMS, e-commerce and app builder platform - https://sitegui.app - solo in order to keep the cost down before it gains enough growth momentum. It is built by one to be extended by other developers/freelancers. Now AI also is a part of the platform too (AI App Builder & Integrated AI Agents for chatbot, reporting and automation).

I just tried it and it works perfectly. The color scheme and font size could be touched up to look better. Just out of curiosity, is $10/month enough to cover the (unlimited) API cost? Do you estimate how many percentage of your users will use more than $10 API fee each month?

We build an Agent framework that can leverage existing apps/pages' content as the knowledge source. The agents can also be used to convert/transform app/page content through automation.

I was able to generate documentation for LiteGUi (https://deepwiki.com/SiteGUI-platform/litegui) and the result is quite promising. It captures all the core concepts and visualizes them beautifully.

ciaovietnam — Sun, 09 Mar 2025 01:05:53 +0000

I use SSE to send web users to another page (redirection header) while still processing other long running stuff for them. The result: non-blocking web access, users dont have to wait for all stuff processed to see a confirmation message e.g: a user signs up, you can show them their account has been created instantly while still creating relevant services (e.g: a virtual server) for their account.

New comment by ciaovietnam in "Handling Database Failures in a Distributed System with RabbitMQ Workers"

ciaovietnam — Fri, 07 Mar 2025 05:12:24 +0000

I'm not familiar with RabbitMQ but this is how I built a queue for LiteGUI using Redis.

Firstly, every job gets stored in an activity table with a retry and result column.

If the job should be run instantly without queueing, no queue entry is needed, the retry column is 0 and the result column is filled.

If the job fails for whatever reason, a queue entry containing the activity ID is added to let the queue worker process it later on. When the worker processes the job, the retry column will be incremented no matter of the outcome. If the worker succeeds, the activity will be updated with the result.

If the worker fails to process it and the retry number is less than 5, another queue entry will be added (as the current one is already removed from the queue). When to process that queue entry depends on the retry number, they can be 1m, 5m, 25m, 2.1h, 10.4h, 2.2 days using the following formula:

$interval = 300 * pow(5, ($retry - 1));

This approach also helps in case of queue failure, you can just rebuild the queue from the activity table for entries with no result (or status) and retry number is less than 5.

To be honest, I don't work with queue regularly but I have to implement it anyway. I'm sharing this approach so we all can improve it.

New comment by ciaovietnam in "Ask HN: How did the internet discover my subdomain?"

ciaovietnam — Fri, 07 Mar 2025 03:08:01 +0000

There is a chance that your subdomain is the first/default virtual host in your web server setup (or the subdomain's access log is the default log file) so any requests to the server's IP address get logged to this virtual host. That means they didn't access your subdomain, they accessed via your server IP address but got logged in your subdomain's access log.

Zelle is quite fast but still has room for improvement especially the user experience. I enjoy much better experience in Vietnam where I can send to anyone at any bank instantly free of charge using official bank apps and can widthraw money from ATMs cardlessly using smart OTP.

New comment by ciaovietnam in "Ask HN: What's your blog / portfolio stack?"

ciaovietnam — Wed, 05 Mar 2025 17:51:00 +0000

I built my own CMS system which places WYSIWYG content editor in a sandboxed iframe to avoid XSS. The advantage of this approach is that I can edit HTML directly using the browser's developer console in case the WYSIWYG editor does not support what I want. After all, raw HTML/CSS codes are behind what we see on a website, so I prefer to work with them directly rather than using Markdown. Whatever CMS you use, just make sure it supports changing theme/template and allows custom content to be inserted at different sections on a web page or preferably multiple pages (i.e global content widget). I found these 2 features crucial and make my work a lot easier.

This can happen to any shopping cart that lets shop owners add custom codes/plugins to the checkout page. Though that enhances the look and feel, I dont think it is a good idea. The checkout page should use a universal design (like Shopify's checkout page), it will reduce the chance of XSS attacks.

There are so many CMSes to choose these days, you just need to choose one that fits your needs. For me, I will choose one that allows me to change theme, menu items and add contents to different sections on the page whenever I want.

So cool. I was able to spot Hipopotamus and Meeerkat right away as they are floating and blurry while others stay the same.
