So many things these days I just love being an engineer rn - ai scheduling assistant - polymarket trading bots - ai assisted form filler - games my 6 y/o dreams up - openclaw workflows - and countless hackathon-y projects at work that never would have seen the light of day without my best friend Claude

Charles Proxy 7 months ago

I once used Charles Proxy to change all the game configs for Candy Crush Saga on my phone back in 2013 by intercepting and replacing the API requests - I made all the puzzles have 1-2 colors and infinite powerups. I guess they didn't care much about the security because I ended up spending way more time in the game

They are when the only reason they are flagged as security updates is because some a single group deems a very rare, obscure edge case as a HIGH severity vuln when in practice it rarely is => this leads to having to upgrade a minor version of a library that ends up causing breaking changes.

This is the recent thread I'm down. Pandas 2.2 broke SQLalchemy backwards compatibility: https://stackoverflow.com/questions/38332787/pandas-to-sql-t... + https://github.com/pandas-dev/pandas/issues/57049#issuecomme...

I spent 10 hrs this week upgrading our pandas/snowflake libs to latest bc there was apparently a critical vulnerability in the version we used (which we need to fix bc a security cert we need requires us to fix these). The latest versions are not major upgrades, but completely changed the types of params accepted. Enormous waste of time delivering 0 value to our business

Like top comment, my first exposure to programming was basic on a ti-86 (better than 83, but quickly outdone by 84 shortly after)

My first program was doubly cheating, not only did I have a program for solving quadratic equation, but I copied the basic off the internet in true open src fashion

When I told my dad I copied code from internet, he was so disappointed and thought I had 0 skills. Now, we pip/npm/etc install anything and are heroes for choosing to "buy" not "build"

Always happy to see new stuff on the block, but hard to leave pandas and python ecosystem for this

Not sure where this fits in to any workflow tbh, with sufficiently large datasets, you will inevitably need spark (which has same API as pandas)

I haven't used Codespaces, but how does this work with databases? A common problem we have during onboarding is getting your local database (MySQL) setup properly: run all the migrations => load some sample, de-identified, production-like data => update certain rows to allow for personal development (e.g. for our texting service, make sure you text your own phone number, instead of someone else's).

What's the workflow for this?

A related issue for us is being able to test another developer's pull request with database migrations without wiping out your current database state. Is there a Devpods workflow for this?

Client-only is the prime selling point for me. A common project for our engineers is building/updating data ETLs & reports off of sensitive healthcare data. Since our engineer's laptops are already fully configured and registered to handle this sort of data, we wouldn't have to worry about the security/tracking of each developer potentially sending this data to more places than it needs to be.

Looks v cool, but I feel like I'm missing a big part of the story, how do 2 app 'servers/process' connect to same sqlite/litestream db?

Do you 'init' (restore) the db from each app process? When one app makes a write, is it instantly reflected on the other app's local sqlite?

Sempre Health | Senior full-stack engineer | Remote/San Francisco | Full-time | semprehealth.com

Series B | 35 employees / 5 engineers | 100% YoY growth in patients

One in three patients in the US skips taking their medications because their copays are too high. At Sempre, we improve adherence by offering discounts for taking medications on time. We engage with patients entirely over SMS.

We are looking for engineers to architect, iterate, and scale the Sempre product to hundreds of thousands of patients nationwide. Our challenging technical problems include building an SMS bot with our patients, optimizing our pricing algorithm to drive the most adherence per dollar spent, and scaling our systems to serve hundreds of thousands of patients this year.

An example message from one of our patients: “Wow you have saved me so much money, I can Truly afford my prescriptions so much better and I don't have to panic when I go to pay for it thank you again”

Sempre Health | Software Engineer | San Francisco, CA | Full-time | Onsite eventually (remote for now)

Sempre Health uses dynamic pricing + SMS to reduce patients’ out-of-pocket spend on drugs. 1 in 3 patients skips taking their meds because they are too expensive. We’re on a mission to fix that. Patients receive texts like, “If you pick up your rx by Sunday you’ll pay $20. If you wait until next week, this goes up to $30.” Then, wherever they fill, Sempre’s integrations with the pharmacy switch, ensure they get the right price.

The product we’re building helps patients afford medications they need. As our fourth engineer, you will have both autonomy and responsibility. You will decide and own the most important projects. You will design new products and features from scratch, get team buy-in, implement, and deploy. You will work cross functionally with patient operations, data science, and business development teams to deliver and see the impact of your high impact products. We won’t add significant process, checks, and balances to your flow - we trust each other to produce high quality work.
