wainguo··on The safest job from AI may be writing
“Writing will remain valuable” and “writing is a safe job” are two very different claims.

AI doesn't need to write better than the best humans. It only needs to be good enough to replace a large part of the mundane paid writing that used to support writers while they developed their craft.

wainguo··on Show HN: Arc Raiders companion – Quest tracker,maps,crafting and bots weaknesses
I created https://arcraiders.website, to help you manage your stash. And with the Loadout Crafter, you can now prepare your raids, by knowing exactly what to loot topside (materials and items that recycles into the materials you need). Give it a try, and please share your feedback if you have any. Good Luck Top Side!

Not use other specific libraries, only the in browser canvas api.

I think a quick tool online is more convinient for common use cases, without install software. when-ever, where-ever a browser is ok.

however, for professional requirements and use cases, a professional software is a MUST choice.

different requirements, different service to met :)

It is easy to verify that:

One way to demonstrate that all processing is being done locally is to load the website, disconnect from the internet, and then use the site.

Hey, thanks a lot for the thoughtful feedback — really appreciate you taking the time to write this

Totally agree with you on the UX point. I also believe these tools should be almost invisible — just drag, drop, adjust a few settings, and done. I initially added more text to make the privacy aspect clear (since many users don’t realize it’s 100% local), but you’re right — that could be simplified and better communicated with a single line. I’m already working on a cleaner layout with fewer distractions and a clearer “drop zone.”

Good catch on the title too! I started with “PNG to JPG converter” for SEO reasons, but as the app expanded to support multiple formats (WebP, PNG, JPG.), that label became outdated. I really like your suggested phrasing — something like “ImageConverter — Convert images between formats, locally” is a lot clearer and more accurate.

And thanks for sharing Mazanoke — hadn’t seen that before! Love that it follows the same “everything local” approach. I’ll take a closer look; maybe I can learn a few UX tricks from it as well.

Appreciate your kind words and testing it out! If you have any other UX ideas or thoughts on layout simplification, I’d love to hear them

do not use ai,it just crop image, or adjust image dimensions and file size if bulk,it use in browser ability to complete the tasks

Great explanation!

Maybe I should not use the text ’upload’ to avoid the confusion

wainguo··on Hacker and physicist – a tale of "common sense"
Great read! The analogy between physics and infosec is spot-on—both rely on understanding fundamental principles that are often overlooked. The "AES256-over-HTTP" anecdote is both hilarious and terrifying, highlighting how abstraction can hide critical gaps. As a dev, I see similar issues when devs prioritize speed over security basics. Curious—what’s your go-to approach for teaching devs about PKI or mTLS without overwhelming them?

wainguo··on Show HN: I built a no-login website screenshot tool for my non-tech friends
Sure, using browser extensions for screenshots is great, especially for pages requiring login, but not everyone knows how to effectively capture public pages. a website offers a straightforward solution for easy and efficient screenshot capture.

wainguo··on I launched 17 side projects. Result? I'm rich in expired domains
Haha this hits home.

Just renewed a 10-year domain to build a tiny website screenshot tool for my non-tech friends. No login, no tracking, just “paste URL → get image.” https://websitescreenshot.online, Will anyone use it? Probably not. But I love it anyway.

Most of my side projects end up as ghost towns too, but each one leaves a trail of git commits, lessons, and a bit of joy.

Keep building. We’re all in the same club.

Building https://gemlink.app, gemlink is an Internet content collection management platform, which collects efficiently through browser extension, flexibly organizes through websites, and forms a value content network through social sharing mechanisms.
