tzm··on Show HN: Using GPT-3 and Whisper to save doctors’ time
Love this and have had discussions w/ doctors and practitioners about this exact problem. I think extracting to FHIR is key, along with making it searchable as a longitudinal data store for a more robust personal record. Clear need. Would love to help.
tzm··on Tesla confirms 285,000 people bought Full Self-Driving
This isn't what's happening. Anyone who subscribes to FSD has access to current capability features. Like most software services, there are no refunds for software purchased during a billing period.
tzm··on Tesla’s 2022 Collapse Hits 69% After Deepest Selloff Since April
Worth noting the Dow Jones U.S. Auto Manufacturers Index is down 62% YTD.
tzm··on Tesla stopped reporting its Autopilot safety numbers online. Why?
Regarding autopilot from 6 years ago? Please. Fast forward, Telsa has built their own neural chip and vision system that surpasses Mobileye in production and scale. And their new HW3 chip can do 144 TOPS. Let's get real, Tesla out innovated Mobileye with their own closed loop vision system at production scale.
tzm··on Tesla stopped reporting its Autopilot safety numbers online. Why?
They've never had lidar and no.. self driving isn't "falling apart". You have no idea what you're talking about.
tzm··on Show HN: I made a Slack bot that qualifies your sign-ups using GPT-3
I wonder.. could be applied to domain-specific qualifications?
tzm··on ChatGPT passes the 2022 AP Computer Science A free response section
ChatGPT needs to improve on numerical commonsense knowledge and verifiers for calculating math

Stable diffusion for davinci003 is coming
tzm··on Tim Cook is now following Elon Musk on Twitter
Just noticed the new "Automated" tag. Looks like Twitter is starting to expose bots (finally)
tzm··on Can Mastodon be a reasonable Twitter substitute for journalists?
> But Twitter is in crisis. Elon Musk bought it, fired a huge portion of the staff, changed the rules so many times that I’m not even sure what the rules are anymore, and has warned that the company will likely have to file for bankruptcy soon.

Crisis? This assessment seems like FUD vs rationality. Twitter was on the verge of mass layoffs regardless if Elon bought it. In 2021, Twitter's annual net loss amounted to $221 million, a significant decrease from the previous year of -$1.4 billion.

I don't question the growing uncertainty of quality, but to think Twitter is in crisis seems more like media bias pushing a narrative.

tzm··on Why Twitter didn’t go down: From a real Twitter SRE
Looks like 28% of Twitter employees took the offer for 3 months of severance.. not the rumored 75% or 80%.
tzm··on A new wave of electric vehicles
The article assumes production can scale ad infinitum. Batteries pose the biggest constraint to scaling EV production - industry wide.
tzm··on Twitter to employees: all office buildings closed, badge access suspended
This is Elon's moment of Enlightenment, like Neo in the Matrix. If Twitter succeeds, he was the One.
tzm··on Tesla rival Rivian posts losses of $1.7B, with worse to come
They're ramping up production which will take time to see revenue. What I question most is whether the company culture has a sense of urgency needed compete compared to Tesla.
tzm··on China Has Lifted 800M People Out of Poverty
They redefined the poverty line in 2011.

> In December 2011, the Chinese government announced it would lift the country’s rural poverty line from 1,274 yuan per year in 2010 to 2,300 yuan, an increase of over 80 percent. This, once adjusted by the purchasing power parity of 2005, is equivalent to approximately US$1.80 per day, a threshold well above the US$1.25 used by the World Bank for international poverty comparisons.

tzm··on SpaceX is now building a Raptor engine a day, NASA says
Agree to disagree. I'm very (very) familiar with their manufacturing abilities in automotive. Tesla is absolutely bending traditional supplier capabilities. It's a fact. Ask any Tesla supplier and they'll agree.. expectations are next level (compared to traditional) in almost every aspect.

No other automotive company is achieving this level of OpEx efficiency: https://i.imgur.com/ZroV0by.jpg
tzm··on SpaceX is now building a Raptor engine a day, NASA says
Yes, Tesla is orders of magnitude more efficient than industry. They also maintain the highest profit margins in the industry (14.95% vs 4.32%).

For comparison, if Toyota was as efficient as Tesla they would've posted 2022 Q3 profits of ~$24 billion, not $3.1B. Tesla achieved $3.9B from only 344k cars. Operational efficiency is their leverage.

Cars sold (2022 Q3)

Toyota: 2.6M (+5% y/y) Tesla: 344K (+42% y/y)

Operating profit excl. FX impact Toyota: $3.1B (-38% y/y) Tesla: $3.9B (+97% y/y)

tzm··on SpaceX is now building a Raptor engine a day, NASA says
Interesting how both SpaceX and Tesla's operational efficiency is much higher compared to industry.
tzm··on BuiltWith: $14M ARR, no employees
Love the concept. I once owned SiteCrunch.com and had a similar idea as BuiltWith in 2013. It was one of many ideas I had, but didn't find validation. ¯\_(ツ)_/¯
tzm··on Boston Dynamics and five other tech firms pledge not to weaponize their robots
Meanwhile in China: https://twitter.com/LiaWongOSINT/status/1577209925255561216

tzm··on Andrej Karpathy leaves Tesla
Fully vested and widely respected. Great position to be in.
tzm··on Vite – Next Generation Front End Tooling
Last I tested Vite (6 mo ago) it didn't support web3 lib and a few others. Has anyone tested recently?
tzm··on Job interview questions engineers should ask, but don't
I almost always evaluate the company / team / product from an investor standpoint prior to joining any role (engineering or management). Most people find it funny, odd or refreshing to see conversations turn into an investment of time and resources etc.
tzm··on Arkansas Bill (2021) Establishing a Database for Tracking Women Seeking Abortion
>To create the Every Mom Matters Act; To provide healthcare support to pregnant women in Arkansas; And to stabilize families and reduce the number of abortions performed in the state. And for other purposes.

Everyone who calls the hotline (per legal requirement) would be entered into the database. The hotline is in Texas, costs $175,000 to set up and $4.8 million to operate. Expected to be functional by 2023.

tzm··on Supreme Court Overturns Roe vs. Wade
Abortion tourism will emerge.
tzm··on Ask HN: Feel bad about working in crypto, what to do?
Traditional banking has far more scams than crypto and is ripe for disintermediation. In fact, the average person spends almost a month a year to pay for the "right to use" traditional finance systems.

It's inevitable that defi (programmable money) will replace tradfi. Stay focused on creating value. Ignore the noise.

tzm··on Tesla to Cut 10% of Jobs
> "seen by Reuters"

Do you find it odd that all the stories coming out refer to this single Reuters statement?

tzm··on AI-art isn't art: DALL-E and other AI artists offer only the imitation of art
Here's a test for you. Is it human or computer generated?
