dgelkson Ask HN: What are you using to parse PDFs for RAG?

Previously have used https://github.com/pdf2htmlEX/pdf2htmlEX to convert PDF to HTML at scale, could potentially try and parse the output html to markdown as second stage.

dgelkson Silicon Valley Bank vice president sentenced to 15 months in prison

Agree regarding the details - I'm guessing unrelated given the indictment was over a year before the collapse "On Jan. 13, 2022, a federal grand jury indicted Gad"

dgelkson Ask HN: Founders, how much automated tests do you write?

Agree with this totally, additionally if you are unsure if you will proceed with an idea with no users, getting something done and receiving feedback as fast as possible is better than doing it perfectly the first time.

That said at my last company after 12 months we hired a few engineers so we had to transition to requiring tests for new functionality. This was just to stop regressions and make sure we could continue moving quickly.

dgelkson Ask HN: Founders, how much automated tests do you write?

Last company, no tests for the first 6 months. Current company after 2 months, have some unit tests for complicated parts in place, will start writing tests once bugs are resolved.

I guess it really depends on what your company is doing, experience of the team and the language/tech you are using.

dgelkson Ask HN: What's the best lecture series you've seen?

dgelkson Show HN: HowdyGo – On-Site Video Chat

Co-founder of HowdyGo here, would love any feedback people might have.

I built HowdyGo because at a former company I founded, we had a small addressable market, high-value leads, and unfortunately very long sales cycles.

Our customers needed time to build trust in the product we offered and that meant it was a necessity to have actual conversations with them, not text chats.

dgelkson Ask HN: How to learn sales?

Similar background to yourself as an engineer, not in sales but as a co-founder often find the sales process a big part of my job.

We've implemented Strategic Selling see https://www.amazon.com.au/New-Strategic-Selling-Successful-C... which provides a great structure for us and a unified language inside our organisation.

Maybe not as useful if you're just trying to get started but does provide a structure to understand the sales process and why a sale closes or doesn't close.

dgelkson Ask HN: What the best way to optimize images in S3?

For this sort of work I found using a lambda function with a trigger on s3 upload works very well, aws-lambda-image seems like a popular project to use instead of writing your own code https://github.com/ysugimoto/aws-lambda-image

dgelkson Ask HN: What are pros and cons of PostgreSQL and MySQL?

Just downloaded and will investigate - thanks!

dgelkson Ask HN: What are pros and cons of PostgreSQL and MySQL?

We didn't select MySQL on the basis of having SequelPro obviously, that would be insane. However if you are still using MySQL and want to switch over to PostgreSQL (like us) a major reason not to be not having SequelPro. Most other factors about PostgreSQL are better but just not enough for the effort to migrate to be worthwhile.

dgelkson Ask HN: What are pros and cons of PostgreSQL and MySQL?

Agreed, Sequel Pro is far above anything I've seen in Postgres and is the primary reason we are still using MySQL in production - business team just love Sequel Pro too much

dgelkson Ask HN: What services are down because of the S3 outage?
