Show HN: A ready-to-adapt email marketing sequences database

Hacker News - Tue, 11/19/2024 - 6:51am

Hey HN, as an email marketer for the past 4 years, I’ve built sequences that reach millions of inboxes every month. But whenever I start a new project—or when a company reaches out for help—it was always almost back to square one: researching from scratch, especially when entering an unfamiliar industry.

Really Good Emails and similar resources are awesome, and I use some of them every now and then. But to me, they lack that strategic part of email marketing.

So, a couple of months ago, I started building a database of email sequences, which now has examples from 80+ companies and over 330+ categorized and sequenced emails. It’s designed to help non-marketers, solo founders, and busy teams create better email campaigns without starting from scratch.

I’d love to hear your thoughts or any suggestions for improvement. Thanks for taking a look!

Show HN: Logprobsvz – log probabilities visualization of OpenAI GPT

Hacker News - Tue, 11/19/2024 - 6:48am

Hi HN,

Today I wrote a simple tool to visualize the log probabilities of OpenAI GPT completions.

It's designed for debugging and understanding GPT's behavior by showing the probability of each candidates, with which you can know when GPT is hesitating and when it is confident of what it's talking about.

Basically it's a remake of the OpenAI Playground but with all the models and all the API parameters available.

I would recommend forking the repo and check the code before inputing your credentials if you do not trust the version hosted by others.

Thanks for checking it out!

Ask HN: What are some of the best take-home coding tasks you've gotten?

Hacker News - Tue, 11/19/2024 - 6:40am

As an applicant, I've personally had a mixed experience with take-homes. We're designing the technical interviews right now, and I thought I'd ask for some stories on exciting take-home tasks. We're looking for something that resembles the actual job, so we'll allow any tool (including AI and debuggers).

Also curious to hear about any bad ones you've done.

Show HN: Embed an SQLite database in your PostgreSQL table

Hacker News - Tue, 11/19/2024 - 6:02am

pglite-fusion is a PostgreSQL extension that allows you to embed SQLite databases into your PostgreSQL tables by enabling the creation of columns with the `SQLITE` type. This means every row in the table can have an embedded SQLite database.

In addition to the PostgreSQL `SQLITE` type, pglite-fusion provides the `query_sqlite`` function for querying SQLite databases and the `execute_sqlite` function for updating them. Additional functions are listed in the project’s README.

The pglite-fusion extension is written in Rust using the pgrx framework [1].

----

Implementation Details

The PostgreSQL `SQLITE` type is stored as a CBOR-encoded `Vec`. When a query is made, this `Vec` is written to a random file in the `/tmp` directory. SQLite then loads the file, performs the query, and returns the result as a table containing a single row with an array of JSON-encoded values.

The `execute_sqlite` function follows a similar process. However, instead of returning query results, it returns the contents of the SQLite file (stored in `/tmp`) as a new `SQLITE` instance.
