arjunlol··on AI Broke Coding Interviews
In the short term this probably means companies will shift to in person interviews.
arjunlol··on Show HN: BemiDB – Open-source data warehouse with zero-ETL
Thanks Vlad, appreciate it!
arjunlol··on Ask HN: How do you promote your personal project in limited budget?
This blog post could be helpful https://refactoringenglish.com/chapters/write-blog-posts-dev...
arjunlol··on Show HN: Bricks – One Click Dashboards from Your Data Using AI
Looks cool! It'd be great to play with it without needing to log in. I'd recommend prompting for login on the second prompt, after initial value seen.
arjunlol··on Ask HN: How will the tariffs affect investor funding?
I think it's early to tell. But generally tariffs = more uncertainty = tighter capital. If a startup raised high before, it might have to do a down round in the future unless growth is real.
arjunlol··on Xata Agent: AI agent expert in PostgreSQL
Looks cool! This may actually save a lot of manual dba work for myself
arjunlol··on Show HN: ETF Comparison – See Correlation, Overlap, and Holdings
Tried it out briefly—this is great. I'll use it more to double-check my portfolio for ETF duplication. Bookmarked!
arjunlol··on Launch HN: Double (YC W24) – Index Investing with 0% Expense Ratios
This looks great. I'm usually very much a DIY type of person when it comes to investing because of the typical fees mentioned, but excited to try this out!
arjunlol··on IronCalc – Open-Source Spreadsheet Engine
Looks cool! What sort of different solutions do you imagine devs building on top of the engine?
arjunlol··on Show HN: BemiDB – Postgres read replica optimized for analytics
Thank you Lucas!
arjunlol··on Show HN: BemiDB – Postgres read replica optimized for analytics
Thanks! Give it a try and let us know any feedback :)
arjunlol··on The EU's AI Act is now in force
Classic EU
arjunlol··on What Is Entropy?
ΔS = ΔQ/T
arjunlol··on The magic of small engineering teams
This was particularly bad at Meta pre-efficiency push Zuck. There was huge bloat that was counterproductive. Empire builders were incentivized by promotions based on the size of their orgs.

One thing the article didn't mention is how crucial it is for a team to have focus and to ruthlessly prioritize. It's easier for bigger teams to fall into the trap of doing "busy work" and people fighting for scope on their performance reviews. This is the worst possible outcome for company and employee where you have work driven by optics vs value.

arjunlol··on The Ultimate Guide to PostgreSQL Data Change Tracking
Hey I'm one of the maintainers of https://github.com/BemiHQ/bemi that was recommended in the article. Please feel free to ask me any questions!
arjunlol··on The Ultimate Guide to PostgreSQL Data Change Tracking
It depends on your reliability and performance constraints. I'd recommend just doing this via hooks on the application layer if it's a simple application. If you're building a production scalable application that required reliability guarantees - you can do this with https://github.com/BemiHQ/bemi too (I'm one of the maintainers from the article). I saw you mentioned you're using Node.js, check out the Bemi github there's a few Node.js compatible libraries too. Feel free to ping me any q's!
arjunlol··on Implementing system-versioned tables in Postgres
This is actually what we're building @ Bemi https://bemi.io/

We're hoping to make it so that this becomes automatic with Postgres vs moving to specialized databases.

We recently open sourced the core tech that implements system versioned tables https://github.com/BemiHQ/bemi, check it out if interested :)

arjunlol··on Bemi: Data Change Observability for Ops
Thanks throwaway-blaze! And that's actually very interesting to hear that you've already covered something like this using Amplitude events. Do you remember what your initial motivation for doing this was? Were you trying to capture server-side state transitions for analytics or for troubleshooting purposes?
arjunlol··on Bemi: Data Change Observability for Ops
Thank you for the interest! We're too early stage to start hiring right now. Let's stay in touch for now, can you DM me?

For anyone else that's interested in getting involved - we have some open-source libraries that we'll work to make more accessible for contributions down the line. Stay tuned for updates, and appreciate the interest!

arjunlol··on Bemi: Data Change Observability for Ops
Something like that :)
arjunlol··on Bemi: Data Change Observability for Ops
Yup so you got it exactly right that Bemi is higher level than Debezium. We actually do use Debezium under the hood, but we also enhance this lower-level data with context via lightweight application libraries. So we're integrating at both the database and application layers on the write side.
arjunlol··on DevDocs
Awesome, this is a great project
arjunlol··on Show HN: Watermelon – GPT-powered code contextualizer
I'll message you, it'd be great to chat! I was working on https://bemi.ai/, which was pretty early stage. Also random suggestion- I don't think there's a need for the homepage header text & image to be delayed showing with the side swoop in animation, or at least the delay timer could be lessened. I found myself almost scrolling past without seeing it when I tried reloading your page.
arjunlol··on Show HN: Watermelon – GPT-powered code contextualizer
This is great! Also awesome that it's open source. I was actually in the process of building this exact thing, I'll pause on that. I'm curious- what size companies do you envision as your target customer? And have you gotten any pushback yet about security/compliance concerns?
arjunlol··on Show HN: Generate regex patterns from examples
Thanks! I actually haven't open sourced it yet. Would you be interested in contributing if I open sourced?
arjunlol··on Show HN: RegexGo – Regex Generator from Examples
Updated to show a screen cap for now!
arjunlol··on Show HN: RegexGo – Regex Generator from Examples
Good point
arjunlol··on Show HN: RegexGo – Regex Generator from Examples
Yup my bad, I didn't think anyone would be interested in regex tweaking on mobile and got too lazy updating the frontend to be good for a mobile workflow. Will update to not just have this text soon!
