Who told the agent to write the blog post though? I'm sure they told it to blog, but not necessarily what to put in there.

That said, I do agree we need a legal framework for this. Maybe more like parent-child responsibility?

Not saying an agent is a human being, but if you give it a github acount, a blog, and autonomy... you're responsible for giving those to it, at the least, I'd think.

How do you put this in a legal framework that actually works?

What do you do if/when it steals your credit card credentials?

krapht · 10 hours ago

The human is responsible. How is this a question? You are responsible for any machines or animals that work on your behalf, since they themselves can't be legally culpable.

No, an oversized markov chain is not in any way a human being.

was just chattin zulip in another thread. news to me that there is a setting for disabling topics which puts thing in a normal "chat room" style chronological order though it looks like it still retains some sort of topic visual heading which looks kind of noisy.

zulip is the most solid of the open self hosted solutions so far imo. last my team tried it sometime a year ago maybe we were super turned off at the threaded topics. my entire team hates them and anyone trying to post important stuff in topics gets ignored lol we can't help it our brains just don't want them in our lives.

but now seeing that there's a way to disable that, it's possibly time to revisit zulip

Why not have a megatopic for things that don't need their own topic?

Topics are necessary when you start having a huge Zulip server, 100+ people. There's so much noise --- dividing things by channel is too coarse.

I participate in several open source Zulip servers and it reminds me of a better IRC. It's a lot more ergonomic that Gitter or Discord.

Having worked in large corporates (and some government projects) issuing out RFPs, the final decision tends to go: let's just go with an established name like PwC even if they're more expensive (and given we have the budget approved already) as opposed to a small firm down the road that has a great portfolio, because if something goes wrong, I can say I relied on this big, proven firm, and not be criticized for using an unknown firm for such crucial work.

It's frustrating, because these larger firms most always churn out subpar work and this mindset just keeps funding it so they don't improve.

krapht · 15 days ago

I've seen some small firms crash and burn too, though. The problem is small firms are easy-come, easy-go; they don't have enough reputation at stake. Not sure what a good solution is.

Yeah, I know three - one transitioned to teaching, another to being a paramedic, and the last to social work.

On the other side I also know a teacher who switched to cyber security for the money after he started a family.

You have to know yourself and what motivates you to know if you'll find things more meaningful elsewhere.

bikelang · a month ago

This is super cool. I’ve been kicking around an idea for ages regarding tile-based routing that I think would be excellent for offline routing. You could leverage the quadtree aspect of tiling to encapsulate faster, direct routes (ie highways) and as you go to deeper zoom levels you’d unlock small roads - even down to pathways. This keeps your in-memory graph small while traversing large distances (which would just be highways anyways) and once you eliminated most of the distance your remaining graph traversal on local roads would be small

What you suggested has been done before - you might find a review of the literature fun if this sort of thing interests you, even if academic papers are pretty dry reading normally.

krapht commented on Roomba maker goes bankrupt, Chinese owner emerges news.bloomberglaw.com/ban... · Posted by u/nreece

mzhaase · 2 months ago

There is also another thing where quality Chinese products are very cheap compared to western products. Since Chinese engineers are cheaper, they can live with lower margins on their products.

A roomba was twice as much as a roborock that was better.

Prusa MK4S is 720 EUR, the arguably better Bambu Lab A1 is 260 EUR.

krapht · 2 months ago

It wasn't labor costs that made the Roomba twice a Roborock, but manufacturing costs. Roomba teardowns basically show that iRobot was just really bad at cost-optimizing their vacuums for mass production.

OMSCS grad here. The awesome thing about the program is its flexibility. Some of the courses are definitely more time intensive, but I think if you took only one class and dedicated about an hour a day to the course materials, you'd be in good shape. (I know that's still a lot to ask of someone with two young kids.)

krapht · 2 months ago

There's no way to get through the harder courses in the program on 1 hour a day. And you're not getting value from the degree if you aren't pushing yourself to take those hard courses, unless you just need the diploma.

This is a standard which few kernels will ever meet. I'd say requiring a numerical proof is the same as requiring no proof at all - because it won't ever happen unless you're validating silicon or something equally expensive.

Here is the basic theory:

Classical and neoclassical economics tells us that people always spend their entire paycheck on consumer goods (consumption) or claims to future consumer goods (savings). There is no money left over at the end of the month. Producers are notified in advance what to produce. If a worker happens to have $5 left at the end of the month and he wants to buy a car, he will use those $5 towards a non-refundable deposit, even if the car costs tens of thousands of dollars, and contractually obligate himself to spend the remaining money. No money is ever carried over from one period to another, since money is neutral and just a veil.

Meanwhile the observation in the real world is that people often hold onto enough money to make the full purchase. From a theoretical perspective it means they have found a third option: delay making decisions, which is neither saving nor consumption. This means producers are not notified of what to produce until the very moment of the purchase, which means producers have to engage in speculative production ahead of time with no guarantee of a sale. They have to hold inventories and possibly throw away unsold inventories (because no seller wants them). This holding of inventories can manifest itself in the form of idle capital and unemployment as well.

What Silvio Gesell discovered on his farming venture that this delayed decision making is incredibly wasteful, because most products (especially produce) are perishable/non-durable at long time scales, this means that waiting produces waste per unit of time on part of the speculative producers and give the seller of perishables a weaker negotiation position compared to the buyer, who is an implicit seller of money, a non-perishable good. This means buyers or generally people with money are structurally advantaged compared to those who don't. This leads to the conclusion that either money should perish as well, or a more modern interpretation: negative interest is a reflection of rising entropy.

I've seen neoclassicals reject this theory with pretty flismy reasoning, mostly based around the idea that people don't hold cash or positive balances on their account.

Now this theory isn't perfect by any means, but it is pretty interesting and the more you dig, the more it feels like it is pointing towards the correct direction. Meanwhile Keynes proposed a different theory, which is based on the liquidity of assets rather than its durability. Money is more liquid, because everyone wants money. This means you can take money and walk to any seller and buy their goods. Meanwhile as a seller, you must have the particular good that the buyer wants. This is a more general theory since it isn't biased exclusively towards money, because there is sort of a hierarchy of liquidity. Bank account deposits are as liquid or perhaps even more liquid than cash. This means bank account balances can be used for payment instead of cash. Bonds are essentially money with a duration that binds their use, which makes their market value and their nominal value diverge. Stocks are on the extreme end of liquid assets, with wild fluctuations. Meanwhile things like apples are on the lower end of illiquid assets. There is a limit to how many apples a person accepts as "payment" for parting with money.

Why can't delayed spending be categorized as a claim to future goods (savings)?

C++: "look at what others must do to mimic a fraction of my power"

This is cute, but also I'm baffled as to why you would want to use macros to emulate c++. Nothing is stopping you from writing c-like c++ if that's what you like style wise.
