Why? I want to check the url is submitted or not by HN in chrome extension, but don't want to call HN Search API (https://hn.algolia.com) every time for security issue.
Product? The chrome extension based on these data can be find in https://hackernewsfilter.com/ , after install, you can check if an url is submitted or not when every time you open a link.
So if you're using a bloom filter and you don't want to query the search engine, how do you deal with the potential false positive of it already being submitted?
Good question, for now, the false positive is not handled.
One solution is to keep a false positive whitelist (also a bloom filter) in server side, only when the first user reports the false positive url, the link will be joint into the whitelist, then timely distribute to client.
I usually try to avoid commenting on grammar or spelling too much, but it seems like you're a non-native speaker of English, and it's a bit tricky to understand some of what you're intending.
Here's some suggestions that might make the site's purpose a bit clearer (just suggestions!)
On the main page:
"Easily find out if the web page you're reading has been discussed on Hacker News, with no API calls"
On /check:
"Automatically find HN discussions when web-browsing, securely"
and
"Borrow HN community intelligence on every page".
On /status:
"For details about how to use the bloom filter file, check here"
On /feedback:
"I found an issue"
I'm not sure what you mean by "I want to format the url", so I'm not sure what to suggest there.
If you like, I can follow up or file an issue, with suggested rewrites for /faq. There's a lot more there than can fit in a single post.
This is cool. I like that websites I visit won't get recorded by someone else however this needs to be open source. I no longer install Chrome plugins that are not open source or coming from very well known public companies.
Not sure you'll make money from this service but with this talent it seems you can easily segue into other services.
For example, HN doesn't have any usable way to save and retrieve threads that you find most interesting/informative/funny. You've solved half of that already.
Solve the other half and you've basically built a bookmarking service. Some good UI/UX and clever marketing positioning and there's a product probably worth paying for.
On the pinboard.in/popular page, it would be useful to have an icon linking to the HN discussion. In fact, lets also have one to the Reddit discussion.
If someone has some time, this could be a useful extension.
Although HN becomes front page of internet for me nowadays, it is still good idea! for submission part, it saves round trip to NH if article has been submitted
Result? 10 year links in HN count is about 2143436, total bloom filter size 2143436 * 2B, file size ~ 5M. Find building status in https://hackernewsfilter.com/status/ . The bloom filter factors can be found in https://hackernewsfilter.com/faq/#check .

Enjoy!
