Truer words have never been spoken. That and planning out your day & thinking through problems in the shower.
jacobkranz··on Warren Buffett's final shareholder letter [pdf]
With all due respect, I think your analysis is wrong. He points out how much luck plays into everything and so even if someone younger with 95 year experience came out I think he'd point out that in the end there's an element of luck to everything. The world isn't deterministic.
jacobkranz··on SpaceX Starship 36 Anomaly
I doubt they’d need to go public. Regardless of your views on Elon, he’s consistently raised billions privately whenever needed. Even without Starship, SpaceX seems cash-flow positive and profitable thanks to Starlink and Falcon 9. It’s simpler to ask private investors to back his R&D efforts when they’re investing in an already profitable company excluding the R&D. Going public might echo Tesla’s early days, when profitability of the company as a whole wasn’t guaranteed.
jacobkranz··on SpaceX Starship Super Heavy Project at the Boca Chica Launch Site
I was under the impression they can't due to ITARS / it being technically rocket technology. I know EU launches from French Guiana but that's still technically France or at minimum has a deep relation
jacobkranz··on Show HN: Non.io, a Reddit-like platform Ive been working on for the last 4 years
This is why I've been so curious as to exactly what Reddit is really trying to do with this api change. If the point of Reddit is to consume content then the content itself (and the amount of it consumed) is really their business model so all actions should support that vs. getting people to arbitrarily be on their site. If your business is content, it shouldn't matter if it's a third-party app or if it's on your main site. I just cannot figure out the long-term logic behind this move (ofc short-term it's about $$ and their IPO but this'll hurt their model in the long-run)
jacobkranz··on A cryptocurrency company had a $65M bill, per Datadog’s Q1 earnings call
My company came up with a structure where we have an overall quarterly revshare in replace of bonuses for the entire company. It works where engineers get X% and sales reps get ~4 x X% of the revshare pool for each team. Of each team's bonus pool, 2/3 is given out guaranteed based off a few tangible factors and then the remaining 1/3 is given out to individuals who have performed above & beyond.

The idea behind this are a few-fold but essentially:

As an engineer (now CEO/CTO), I've hated having to wait the full year for my bonus. It's just a way to lock me in for the year when my incentive to stay should be to love the work & team. I don't want to create a place to work where you're forced to stay because of some guaranteed bonus - if you want to leave, leave & then let's hire someone who finds the work engaging + we all know performance slips as you wait for the bonus.

For the sales team, it means they're incentivized to work with the engineering & product teams to make sure they get the engineers the proper feedback in order to build a better product that they can sell more easily.

We've found this has generally built a better more team-oriented & results-oriented culture. Happy to expand but overall I think a quarterly revshare for everyone is a much better end-result (other than the fact I'm now forced to care more about making sure engineers are happy but that should be a huge focus regardless...).

Edit - also worth noting that we give everyone equity so there's still a long-term focus of building a company, not just cashing out quickly.

jacobkranz··on Ask HN: Most interesting tech you built for just yourself?
I wrote a Go library for postgres & redis that handles all caching automatically.

where all you do is input the queries your application needs and then it will automatically determine which columns are affected & do all caching / cache invalidation for you.

I have it to the point where due to Redis being able to push onto a list that only writes hit the database & it even will update the cache keys automatically so that after an insert or update the cache is still hot.

jacobkranz··on ShareGPT: Share your ChatGPT conversations with one click
Two quick examples:

1. In our codebase, we leave links to the stackoverflows as documentation if it's something that someone else may question. Exact same concept just with ChatGPT.

2. I'm working with the Salesforce API which has been absolutely tedious to use but chatGPT, while not great at everything, has been giving awesome results back that otherwise would take me hours to hunt down. Sometimes responses get a lot of information back with multiple code blocks that I'm then unable to copy paste over & I'd rather send the conversation than spend 15 minutes typing back & forth explaining myself to a co-worker.

I completely understand you may not have a use for this but I think there could be awesome use-cases for it nonetheless for other engineers.

jacobkranz··on ShareGPT: Share your ChatGPT conversations with one click
I’m actually really excited for this because I use chatGPT all the time for work and being able to share the output of code to another engineer will make things a lot easier. I agree with others about it not being useful for mundane things but there are times chatGPT will generate a lot of code in different blocks & it’s a pain to share.
jacobkranz··on Show HN: I'm a doctor and made a responsive breathing app for stress and anxiety
I agree. It's felt like a lot of online forums are starting to become Quora where it's all self-promotion thinly veiled as adding to the conversation. It reminds me of PG's The Submarine blog post (http://www.paulgraham.com/submarine.html)
jacobkranz··on FTX owned an $11.5M stake in a tiny rural bank in Washington state
I want to see him in jail just as much as you but I’d counter point that: 1. No bodily harm occurred in this act 2. Murder trials are usually easier to get evidence from
jacobkranz··on Tesla rival Rivian posts losses of $1.7B, with worse to come
Except that the DOE loan was for 465m. If they lost 1.7m in the quarter then the DOE loan wouldn't even be 1 month of operations. Even with inflation, the loan they received wouldn't touch the losses rivian has been having.

I do love their trucks and hope they succeed though

jacobkranz··on Coinbase announces proposed direct listing
Could you do what Mark Cuban did and work with your brokerage to do sell calls & buy puts around the strike? That would lock in your price for a given amount of time.
jacobkranz··on Ask HN: Anyone know any funny programming jokes?
The two hardest problems a programmer faces:

1) what to name your variables

2) cache invalidation errors

3) off-by-one errors

jacobkranz··on Jack Ma's disappearing act fuels speculation about billionaire's whereabouts
This is pedantic but seeing as the other comment is joking about his appearance then I do want to say that China is civilized. To say it's china vs. civilized is wrong at best and helps dehumanize billion plus people at worst by implying they're not civilized yet we inherently are. I do agree with you on your point overall though.
jacobkranz··on Tesla Earning Result 3Q 2020 [pdf]
I believe they spent 2.4b on expansion but cashflow was still 1.9b.

`Over the past four quarters, we generated over $1.9B of free cash flow while spending $2.4B on new production capacity, service centers, Supercharging locations and other capital investments`

jacobkranz··on Tesla Q1 2020 Update
According to their loan agreement w/ China, they must pay off their loans until they can repatriate anything.
jacobkranz··on Stocks Up $1T Since October
I’m the short-term, yes. The assumption is that the company cannot invest the cash into its operations at a larger rate of return than an individual investor could therefore the company (whose sole purpose is to enrich the shareholders) should return the cash.

In a way, the company has an earnings yield of EPS/stock price (or inverse PE). If the company cannot invest the money in its operations that makes a larger return that the earnings yield then the stock is actually a better investment. The huge issue is that when markets crash is when technically a company should be buying back tons of its stock but rarely do companies ever do this and instead elect to hoard cash when buybacks are best & spend money on buybacks when it’s the worst ROI (when the market is hot & earnings yield is minimal).

jacobkranz··on Texas Power Prices Briefly Surpass $9k Amid Scorching Heat
I was one of the first Griddy engineers (though I’m no longer there). We would have people call & complain when the cost for a day was much less & they had AC blasting. I wonder how the customer support reps are dealing with all of this.
jacobkranz··on How the Stock Market Works
I heard through a realtor / friend that during '08 there were some home equity loans that were called back though. I don't know the exact details of those who had their HEL's called but my friend stressed that mortgages would never be called back (unless capitalism collapses) but HEL's could be even if you're making on-time payments depending on terms.

jacobkranz··on Tesla cuts prices as Model 3 deliveries narrowly miss estimates
I think OP's point is that Tesla isn't just a car company but they're also an energy storage & solar producer. While the car biz may have be leveling off (and that's not accounting for the semi & modely Y launching this year and next respectively), their energy storage is starting to take off along with the solar roofs so this provides huge growth opportunities in the future.
jacobkranz··on Tesla to achieve leading $100/kWh battery cell cost this year, says investor
Regarding their seats, that line seems to have been going really well. EM said it hasn’t been a bottleneck and they can scale their seat production too very easily. If anything, I see that as a sign that their vertical integration is working, even with Munro & Associates going as far as staying that they were floored by the margins the model 3 was getting.
