gsharma··on Report: Tim Cook could step down as Apple CEO 'as soon as next year'
No, it’s the other way around. Comment above is confused about the relationship.
gsharma··on Occasionally USPS sends me pictures of other people's mail
My HN username is also my gmail. I've got most of the stuff you mentioned, including unencrypted copies of US tax returns (with SSN) and house buying paperwork.

> I used to reach out and tell them I didn't sign up for their service. But honestly, after doing it for a few years I gave up.

Same here. It's surprising that most of the services don't use double-opt in before sending emails.

Some day, I want to use an LLM to identify those emails and label them.

gsharma··on Installed an open source garage door opener, and I'm loving it
Probably this is why MyQ/Chamberlin doesn’t support HomeKit.
gsharma··on Show HN: Free mortgage analysis tool to avoid getting screwed by closing costs
The deal isn’t always about the price. For example, a $1M house bought with $100K down and $900K mortgage is a worse deal for the seller as compared to $500K down and $500K financed. Assumption here is that it is more likely to get a $500K loan irrespective of the appraised value of the house.

A lower all cash offer (say $975K) is likely a better offer for the seller because it reduces the risk for them and closes the transaction much quicker than a mortgage transaction.

I have been a buyer in two transactions where my offer was slightly lower than the highest bidder, but with better terms.

gsharma··on 20 years ago Gmail revolutionized email. It's time for a new revolution
HTML emails were there before, but I agree that fast UI and threads was a step up from Yahoo or Hotmail. Labels instead of folders, username+wildcard@ email addresses, filters (at least the UX was better than traditional rules). They also enabled POP and IMAP. IIRC, IMAP used to be a premium feature for email providers at that time.

I’m not sure about revolution, but e-mail can certainly be evolved.

20 years ago, not as many emails were sent, especially transactional emails. User behavior has evolved since then.

For example, storing email receipt of a random Amazon order from 2 years ago doesn’t make much sense these days.

Hey has addressed some of these changes, but there is a lot of room for improvement.

Initially, people sold these beta invites on eBay!

Not initially. It started with 1 GB at the time the other popular services Yahoo and Hotmail provided 2-4 MB of storage.

Google later changed it to “unlimited” which increased daily by an MB or so. At some point settled at 15 GB.

gsharma··on Launch HN: Retell AI (YC W24) – Conversational Speech API for Your LLM
It seems to be broken on iOS Safari. I got no response after accepting the microphone prompt.
gsharma··on The GPT Store
To be fair, if the GPT creator doesn’t do a good job of explaining the GPT, you can’t really tell even if you pay $20. The only way is to try out the GPT and hope you hit the right features. Chat is a pretty bad interface to discover features.
gsharma··on The GPT Store
I end up creating multiple threads “frontend”, “backend”, etc. but a GPT for the whole project is a great idea!

How do you keep the GPT updated so that it knows about the final decision made for a specific problem. Like if api schema changes or the db is moved from SQLite to Postgres.

gsharma··on Software Engineers Say the Job Market Is Getting Much Worse
Agreed, but Gen AI already has a lot of use cases, the challenges are with “taming” the technology - Rare hallucinations, RAG (or equivalent) figured out, more deterministic.

Assuming some of these challenges are solved, integrations will follow.

Imagine the web before CSS, JS, AJAX. That’s where we are with Gen AI.

gsharma··on Gmail and Yahoo’s 2024 inbox protections and what they mean for email programs
> but you don't think engineers who build web crawlers cannot build email classifiers?

I’ve seen Gmail put legit update emails coming from Google itself in spam.

gsharma··on Mixtral 8x7B: A sparse Mixture of Experts language model
It will probably require some trial and error, but this leaderboard is a good starting point. https://huggingface.co/spaces/HuggingFaceH4/open_llm_leaderb...

~13B models should work well with plenty of room for other applications. Lately, I’ve heard good things about Solar10B, but new models come in a dozen by day, so it might have already been changed.

Ollama is probably the easiest way. https://ollama.ai/library/mixtral

LM Studio is another option.

gsharma··on Ask HN: How do I train a custom LLM/ChatGPT on my own documents in Dec 2023?
I have usually seen people recommend to chunk by sentences or paragraphs or some fixed length of characters. IMO, all these are suggested because they are easy to write code for, but in reality, length of a meaningful chunk depends entirely on the data. The way we chunk an FAQ document vs a PRD is different.

Based on this assumption, I have a couple of questions:

1. Is chunking the most significant factor in RAG quality?

2. If there are no limitations, would humans that are experts in that dataset, be the best people to create chunks?

gsharma··on I bricked my Christmas lights
The Govee strips I have do support Bluetooth connectivity. In fact, that’s how they are setup initially.

Your comment prompted me to search for “Govee LAN” and found HomeAssistant LAN integration. Time to dig deeper!

gsharma··on Tohands – Smart calculator for small businesses
> this would only serve the niche of "not-registered for GST and using cash"

Wouldn’t this segment have an incentive to not digitize their records as they’re evading tax?

This was the case several years ago, not sure if still relevant anymore. People evading tax were only interested in non-cloud solutions for their records.

gsharma··on Show HN: Lume – automate data mappings using AI
Congratulations on the launch! I’d love to see something like this succeed. However, there are some challenges that you might have to overcome. Here are some random thoughts:

Ingest Client Data - You will have to find customers who ingest dynamic data schemas. The example in the video shows more of a standard schema, which can be mapped once (using Lume or otherwise). No need to add an overhead or extra cost to run that data pipeline.

Normalize Data - One of the challenges will be to establish quality metrics for these mappings. Based on the demo, the quality score is supposed to be 100% all the time, but that’s far from the truth. Real data is messy. Validations will catch a lot of issues, but there will still be cases where incorrect mappings slip through. Ability to provide metrics around this will be very helpful in adoption.

Response Time - I’m not sure if you’re using OAI or your own models in the background. Even small latency in the pipeline for 100s of millions of records adds up to hours/days delay.

All the best!

What does your “Gmail” GPT do and what do you use it for?
gsharma··on ChatGPT with voice is now available to all free users
I wonder why they launched it today, when it was supposed to be a week-off for all OAI employees and amidst whatever else is going on?

One possibility is to capture Thanksgiving gatherings as a growth hack where people demo this to their families/friends and increase app downloads for OAI.

gsharma··on Show HN: HackYourNews – AI summaries of the top HN stories
This is very helpful! I see that a GitHub gist/file isn’t summarized and just mentions that it is code. What is the input to the summarization? Do you use the entire HTML (header, footer, sidebar, etc.) for summarization or do you do any processing between crawling and summarization?
gsharma··on Show HN: HackYourNews – AI summaries of the top HN stories
This is a great app! You might want to put Summary and Comments as headings or at least make them bolder for easy scanning.
gsharma··on Someone keeps trying to reset my Facebook password
Same situation here! My HN Username @gmail and my last name is a very common last name in India.

I’ve received people’s tax returns (including their SSN), airline tickets and hotel reservations, matrimonial proposals, photographs, etc.

I often used to email back and let people know about the mistake, but rarely do it now unless there is sensitive/urgent information.

To deal with some of the repeated unwanted emails, I have rules created to label those emails with a specific label. I use Google scripts to auto-delete all emails from that label which are older than 365 days. It cleans up repeated transaction emails from Indian banks/credit cards, newsletters, etc. but also gives me a year to retrieve the email if it was actually meant for me.

gsharma··on Stable Diffusion in C/C++
> sizes smaller than 512x512 (which i tried as 512x512 is quite slow on my PC) sometimes generate garbage (anything smaller than 384x384 seems to always do that).

Not sure about the speed, but the garbage output might be due to the model instead of the library. I’ve always got garbage (using other tools) when I tried 256x256.

gsharma··on Stable Diffusion in C/C++
ComfyUI works pretty well on old computers using CPU. It takes over 30 seconds per sampling step on a 2015 MacBook Air (I7, 8GB RAM).
gsharma··on A Blog Post with Every HTML Element
This reminds me of “frame buster” JavaScript. It was a piece of JS that goes in the site to combat above mentioned behavior and “freed” your webpages from someone else’s content frame.
gsharma··on Launch HN: Rubbrband (YC W23) – Deformity detection for AI-generated images
https://github.com/Bing-su/adetailer works very well on faces and hands.

This is a good solution for all the use cases I’ve dealt with.

Are there widespread use cases where, knowing a deformity exists is required than just fixing the deformities?

gsharma··on Gorilla: Large Language Model Connected with APIs
Congratulations on shipping! This is pretty cool. Building next-gen Zapier on top of this would be a great use of this.

There is a finite number of public APIs (100K?) which keeps the problem manageable. IMO, adding support for custom/private APIs (something like OpenAI functions) will make this a very powerful tool.
