Ask HN: How are you following tech blogs?

Hi,I am curious on how you are following tech blogs? I personally find it a bit tedious that some are on medium, some on substack and others have their dedicated site. Do you use a service to aggregate them?And while we are at it what blog is your favorite?

https://makemap.co/

Hi all!A year ago I build makemap.co with a friend. It is a Next.js page leveraging supabase and stripe in the background.I am keen to hear your feedback on the site, design, wording, or anything else. We are also thinking of expanding the product suite into a full heatmap or printing on mugs and shirts.

Hi!

yes, I started with something very niche and specific, but my plan is to extend this into composing / generating the PDF from scratch. What components would you need for your documents?

Re:Show HN: Fill your PDF templates with an API call - doqs.dev on Sunday August 28, 2022 @11:27AM (#32629127)
Yes, thanks a lot! What a fail by me.

Unfortunately I cannot add it anymore

Re:Show HN: Automatically fill PDF templates per API on Saturday August 13, 2022 @04:40AM (#32447998)
I am running on python and AWS Lambda. Works really smooth battle tested it with 100 pdf pages and 400 fields to be merged and the Pdf is generated within 2 seconds. And I am currently using one of the lowest resource settings on AWS Lambda.

I am mostly using pikepdf and the a lot of secret sauce added ;)

Yes I still have problems with the activation mail. Need to fix this, currently rely on my own SMTP which is not a good idea. Should move to a service.

Is it working for you now?

Why can't you post to a SaaS? Would love to know more.

Interesting! I had a similar idea too, but I really like the classic one. So I probably stay with it for now.

Show HN: Let's Play Sudoku

I was a bit sick lately and slightly bored of lying in the bed. I love to play Sudoku when I have some time to kill. So I thought would be a nice idea to familiarise with PWAs.So I short handedly created an installable Sudoku PWA. Try it! And let me know what you would miss.For now everything is stored in localstorge. But I intent to add a social sign in and then store the profiles / histories...

Re:I am beta launching my micro SaaS: doqs on Sunday May 22, 2022 @07:14AM (#31466920)
The main use case is that you have a document from a third party provider, e.g. bank, government office, etc. which needs to be pre-filled with your data.

My current (financial sector) and my previous employer (energy industry) use such a solution and the existing solutions are very complicated and also way to expensive, IMHO.

Re:I am beta launching my micro SaaS: doqs on Saturday May 21, 2022 @03:58PM (#31461240)
I am beta launching my micro SaaS for filling pdf documents (more to come in the future) and are very keen on your initial feedback!

Cheers, Dennis
