dustingetz··on Raising a $1.5M pre-seed, any advice on getting warm intros?
candidly, you need an unfair advantage - YC network, preexisting network of high net worth individuals, status/prestige/brand from high visibility past work, something. High status angels (such as exited founders) were the best source of intros to VCs for me but those relationships take several years to develop if you don’t have them already. And you need to already have results, or something that gives them conviction. My first few angels were people I was acquainted with for a few years before our early results impressed them and they asked to invest unprompted.

dustingetz··on Ask HN: How do I get good at math as a 42yo with kids?
freshman is “the beginning”, i’m pretty sure this book series is what you want
dustingetz··on Ask HN: How do I get good at math as a 42yo with kids?
Start here: No BS guide to Linear Algebra https://a.co/d/6em7tXE . There’s also a No BS guide to Math/Physics which goes through calculus and geometry. This is freshman level content. I read this on the couch next to my wife act age 37 for about 20-30 minutes a night, a few times per week and got through it in six months. You will need to work some of the exercises, i used a lap desk and clipboard which I store next to my spot on the couch.

different share classes trade at different prices. Employee NSO/ISO strike price at seed stage (i.e. on a SAFE) are typically priced at a FMV of 10% (!!) of the SAFE's postmoney valuation. Also, your use here of the word "fair" has triggered a personal tick of mine so I must direct you to https://quotefancy.com/quote/3709551/Chris-Voss-The-F-word-F...

preferred shares prevent cookie cutter founder fraud. Founder raises $1M at 10 post. Founder decides to sell 6 months later for 2 mil. Investors get 200k back founder gets 1.8 mil. Now run this math for AI unicorns.
dustingetz··on The FizzBuzz that did not get me the job
what is this good leadership you speak of, where did you encounter that?
dustingetz··on I Won't Invest (2019)
in my experience few VCs will explicitly state a rejection on team to a founder's face due to that reason's propensity to generate a hostile reaction

dustingetz··on Ask HN: Apply to YC While Pregnant?
are you the CEO? why would you disclose? YC is like a weekly dinner and a zoom call right? And it takes many attempts to get in anyway. Shoot your best shot and don’t make imaginary problems. Your cofounders can cover for you if you are not CEO. If you need to skip dinners for the last month will the partners even notice? If you are CEO, fundraising in person while third trimester probably not great optically but other than that you can continue to operate, and seed fundraising is done on zoom anyway so again who would even notice if you don’t talk about it, men are clueless
dustingetz··on A versioning scheme for end-user software
For major products we use v3-alpha-789 where 789 is number of commits since tag v3-alpha, v3 is the marketing version, and alpha is the maturity statement, here meaning “stable with new feature work and enhancements in development, minor breaking changes are allowed”. For minor projects we use v20220101-789, which means “read the commit log”. There is a “git describe” flag to generate these strings. The v prefix makes the strings valid git tags.

Advantage of git tags also is they can be assigned after the fact without changing the content hash, which means you can repackage releases under a new name (e.g. to republish a release candidate as stable) without needing any automated boilerplate commits. In Clojure ecosystem there are a bunch of stable libraries with -alpha baked into various places, and no way to fix it without hours of maintainer attention to click stupid buttons and run fragile scripts (with possible breaking changes!, e.g. god forbid you put -alpha in the namespace name, which core actually did). The maturity tag belongs in the git tag!

dustingetz··on I have made the decision to disband Hindenburg Research
zombie companies suck all the oxygen out of the room and away from productive companies, the victim is society and civilization at large and the damage is measured in lost exponential progress of unbound time axis, potentially millennia. Medical technology, longevity, scientific advances that we could have had but will not for another 10^N years - all retarded by malinvestment and misallocation. Theworldif.jpg
dustingetz··on Life on a Closed Timelike Curve
Yes but mirror boxes are not real, except maybe the case of quark color confinement inside a proton?
dustingetz··on Life on a Closed Timelike Curve
Thanks, and LOL:

we will model the spaceship as an idealized box with perfectly reflecting walls. This is necessary, because the second law of thermodynamics applies only to thermally isolated systems, to which we can assign a Hamiltonian [5, section 11] [Landau L and Lifshitz E 1980 Statistical Physics vol 5, 3 edn (Pergamon)].

Chasing down that source: https://ia802908.us.archive.org/31/items/ost-physics-landaul...

§11. Adiabatic processes

Among the various kinds of external interactions to which a body is subject, those which consist in a change in the external conditions form a special group. By "external conditions" we mean in a wide sense various external fields. In practice the external conditions are most often determined by the fact that the body must have a prescribed volume. In one sense this case may also be regarded as a particular type of external field, since the walls which limit the volume are equivalent in effect to a potential barrier which prevents the molecules in the body from escaping.

If the body is subject to no interactions other than changes in external conditions, it is said to be thermally isolated. It must be emphasized that, although a thermally isolated body does not interact directly with any other bodies, it is not in general a closed system, and its energy may vary with time.

In a purely mechanical way, a thermally isolated body differs from a closed system only in that its Hamiltonian (the energy) depends explicitly on the time: E = E(p, q, t), because of the variable external field. If the body also interacted directly with other bodies, it would have no Hamiltonian of its own, since the interaction would depend not only on the co-ordinates of the molecules of the body in question but also on those of the molecules in the other bodies.

This leads to the result that the law of increase of entropy is valid not only for closed systems but also for a thermally isolated body, since here we regard the external field as a completely specified function of co-ordinates and time, and in particular neglect the reaction of the body on the field. That is, the field is a purely mechanical and not a statistical object, whose entropy can in this sense be taken as zero. This proves the foregoing statement.

Let us suppose that a body is thermally isolated, and is subject to external conditions which vary sufficiently slowly. Such a process is said to be adiabatic. We shall show that, in an adiabatic process, the entropy of the body remains unchanged, i.e. the process is reversible.

I am unable to make these statements coherent

dustingetz··on Life on a Closed Timelike Curve
What about entropy? e.g. you send an egg around a CTC, the egg breaks (or like it’s a quantum particle whose wave packet disperses over time, or a bacteria powered by cellular respiration), the system cannot reconstruct without adding energy. So, no life on CTCs and likely not even quantum particles which are unstable and decay? No probability processes at all, not even the quantum vacuum fluctuations and zero point energy

i’d worry more about getting your application read, you ever go through a folder with 18,000 resumes in it? you fog out after like 3. recommendations are the answer to this
dustingetz··on Show HN: Filter out engagement bait and politics on your X/Twitter feed
i followed 1000 scientists on X last year. Quantum mechanics, particle physics, general relativity, astrophysics and cosmology, molecular bio, chemistry, math, microbiology, environment, linguistics, psychology, middle east, islam, French. Oh and work stuff: programming languages, compilers, AI, venture capitalists of all stage. Where else can you find this? The main issue with X is it is a mirror. It puts us in a room with people like ourselves. If you like to argue, it will send you a lot of bait. I just stopped doing that. Muted a few keywords (nazi, greta, trump, elon, gun). And read a lot of paper summaries about black holes! (Oh and unfollowed most of the VCs, that was terrible)

dustingetz··on Ask HN: How to learn marketing and sales as a solo entrepreneur?
you need a coach, for both knowledge and accountability. Sales is hard, you’re going to fuck up important calls and need to postmortem them correctly in order to improve and succeed. In the US a coach starts at about $300/hour (3-5 hours per month) for someone who is successful but not too successful. Which implies - I will state up front - you need to have some money. Otherwise, without a viable team in place with all the necessary skills to succeed, and/or a credible plan to rapidly acquire the skills you are missing, you are gambling not investing and you will pay a much higher cost: failure, liquidation of your personal assets, and liquidation of multiple years of your life, with little to show for it at the end. Ask me how I know this. My company is working now but it took two tries, i.e. i liquidated myself twice before beginning to see success. The first was the price of education. The second was the cost of identifying the right team. I was able to raise some money at this point.
dustingetz··on I am rich and have no idea what to do
help more people. Use your skills and resources to accelerate progress in the areas in which you are sufficiently competent. If my startup exits i have zero doubt that I will continue in this way.
dustingetz··on Ask HN: What's Your Morning Routine?
9:30 asleep, 5:30 wake, get coffee, scroll phone, 5:55 out the door to exercise - run or group fitness class, 7:10 breakfast, shower, 7:30 ET zoom standup with Europe, work until 5:30 (tech founder), dinner with wife, evenings are free, 8:30 bed routine, 9:30 asleep. on gym off days i work the extra 90 minutes. weekends are about the same with personal trainer 7am sunday. There’s plenty of room for kids - work a bit less and evenings are already free - but wife didn’t want em.
dustingetz··on Dropbox Engineering Career Framework
companies do not really have interests, individual people have interests. The founders, the board, investors, executives, managers, ICs, consultants, vendors, customers. Everyone is doing what their manager (customer) tells them to do while capturing enough value for themselves to make it worth it, recursively. This becomes especially clear when interests diverge, the executives screw the employees, the board screws the founders, the founders screw everyone, the managers accumulate unnecessary headcount so they are responsible for more cashflow, the ICs inflate the estimates, the PMs prioritize visible short term features only.

I also recommend Gervais principle as mandatory read for young managers who don’t yet see the game for what it is.
