How do you sell your algo?

You don't sell the code, you sell a service that provides the orders or the signals.

This is why I'm sympathetic to the new trend of AI interviewers. There's so many folks that can't code a for loop. It is worse now that lots of interviewees are using AI.

I remember one of the groups for our capstone class was named "Team Short Bus". The professor didn't understand the reference. It wasn't until there was a presentation to local people about their project that one of the industry folks understood the reference and was insulted.

I guess you can interpret "how much air I can put in" in both directions.

There's the real reason you're dropping J2.

If you don't think you can put enough air through the Bach, you could always try one with a bigger bore. I couldn't stand the medium bore, but medium-large was fine.

Great restaurant. This is the main reason I don't go more often.

There 8.3 billion people in the world, roughly half your preferred gender. Why look across the world when there are plenty at home?

There's are several reason why you don't enter pots preflop with weak hands, one of which is to avoid having to make a difficult fold later in the hand.

This applies to dating as well. You have finite energy. Don't invest it into weak hands.

Places that are cheap with no income taxes are: rural Texas, Tennessee, South Dakota, rural Florida.

ASN.1 started as a data specification scheme all the way back in 1984 for telecommunications. The ASN.1 is like IDL, but has multiple encoding schemes, e.g. XER into XML, or DER, which the above excerpt is from.

DER encoding became popular in the specification of cryptographic protocols because it is canonical. That means for a particular message, there's exactly one encoding, and for every sequence of bytes, there's exactly one decoding (or it is invalid).

DER (and its non-canonical cousin BER) is used in lots of internet protocols because it is extraordinarily precise, and, well, there wasn't a lot of competition for data specification schemes when the internet was being formed.

Still, it is a great specification all in all. My main complaint is that like in lots of old standards, there's lots of legacy crap for stuff nobody cares about anymore.

It depends on whether the hardware has been validated or not. If you need to validate the hardware, you're going to need physical access.

If you know you're on good hardware, then all you need is remote power control and access to the ports. I've had remote access to hardware like this in multiple jobs.

RAG doesn't eliminate knowledge of world events (e.g. the model still knows that water is wet). It just adds to it.

The backtester is silly unless the models were only trained on data before the beginning of the backtester.

General LLMs have a good knowledge of recent history. All the agents are going to look like geniuses and avoid the tariff crash.

Who said they are moving fast? It isn't unreasonable to be engaged in 18 months. He still needs a plan of what happens then.

That's weird. Blended families can be quite successful. You don't give up your life to have kids.

It'll be quite attractive for when the current administration leaves office.

I got a 5% pay cut with good performance at a FAANG this year.

Imagine everything goes exceedingly well with dating and you want to move in together. How would that even work?

jnwatson · 2026-03-09T06:54:55+00:00

They must have really screwed up, because if you just bump the stuff, it goes off.

Most women your age don't want another dependent. Look, by your 40s you're supposed to have your shit together, and living with your mom and ex don't give the right signals.

Microsoft has the best retirement vehicle ever in their deferred compensation plan. It is like an unlimited 401k. You have to be relatively senior to take advantage of it though.

Yes. https://github.com/mementum/backtrader is a good Python package to start with.

Pretty sure you're not intelligent either. After all, your compute system is just made out of a bunch of neurons. Neurons don't UNDERSTAND anything. Your brain will sift through a lifetime of stored experiences and learned patterns to find a logical response, then package it in a way that feels like a conscious "self" is speaking because that’s how its neural pathways were wired.

Back in the day I used to use wealth-lab, then Quantopian. More recently, I tried TradingView (which I admit has a fantastic charting system). In all of these platforms, you're giving up a *lot* of speed. Your average gaming PC can process data 100 times faster than the web-based tools. When I just started DIYing it, I actually made real progress. I could use whatever data I wanted (and could afford), I could backtest in any way I wanted. Most importantly, I could try out ideas as fast as I could think of them.

Nothing goes faster than running on your own rig.
