The analysis of the 2015 article about Triplebyte is fascinating [1]. Particularly the Awards section.

These data points are based on 2023 inflated pricing as the entry point. Not much to see here.

In 2023 the car market was wildly overpriced due to the low interest rates and covid money combined with supply chain problems.

> For Tesla owners in the U.S., their 2023 Model Ys are worth 42% less than what they paid two years ago

It's the standalone Glacier service which I wasn't even aware existed - nothing changes for the s3 glacier storage class.

We have no idea what AGI might look like, for example entirely possible that if/when that threshold is reached it will be power/compute constrained in such a way that it's impact is softened. My expectation is that open models will eventually meet or exceed the capability of proprietary models and to a degree that has already happened.

It's the systems around the models where the proprietary value lies.

Feeling vindicated for the double entry transaction system we built at clearvoice.com for our two-sided marketplace, leveraging the fantastic DoubleEntry Ruby Gem from Envato.

XMPP and specifically ejabberd are what made WhatsApp possible to build with ~50 people at absolutely massive scale (~400M MAU @ 2014 acquisition).

It's unfortunate that Elon has made himself so visibly political, it casts a dark shadow on the great work of the people at his companies.

Linear is the best project management for software I've ever used, highly recommend. They've added many many amazing features this year... Incredible team over there that are just a joy to work with.

Apple doesn't manufacture the chips, they subcontract that out to TSMC/Samsung. In this case Intel is the contract manufacturer, not the chip designer fulfilling the same role as TSMC does for Apple.

The problem is that folks who are hard of hearing want to be part of the conversation and make eye contact. The transcripts in the audio recorder app on Pixel phones is quite good, though combining computer vision and audio processing is necessary for loud and complex social environments.

This is great! Hearing aids are stupidly expensive and I hope we see more solutions leveraging mass production to improve accessibility of hearing aid tech

Another thing I'd love to see is affordable AR glasses with auto captioning for noisy environments with many speakers. My mother struggles with hearing loss, and it's apparent to me that audio-only solutions are not sufficient for many situations and types of hearing loss.

There's a small company already working on auto-captioning, but the price point is currently $5k - https://www.xanderglasses.com/xanderglasses

New comment by jeffnappi in "Urchin Software Corp: The unlikely origin story of Google Analytics (2016)"

jeffnappi — Sat, 10 Aug 2024 16:28:14 +0000

We were Urchin users prior to the acquisition and were also Google AdWords customers...

I remember being shocked at the idea of putting Google's JavaScript in our secure e-commerce site. We wanted to pay as little as possible for traffic and were mining the long tail of keywords. We certainly did not want AdWords to know what our economics were.

Ultimately AdWords evolved into a very efficient system that groups similar keywords and takes as much margin as the advertisers can handle. The golden days of a level playing field in ppc advertising were over and Google won the game :)
