Murky3515··on Seam Carving (2018)
It is true. DP always deals with optimization. Just because my car has a radio, doesn't mean my car is a radio.
Murky3515··on Seam Carving (2018)
You're wrong, and I don't know why you're being stubborn about this. HDP is a different class of algorithms that uses DP, but it is not DP. A basic read of wikipedia of dynamic programming reveals the key pieces of DP:

There are two key attributes that a problem must have in order for dynamic programming to be applicable: optimal substructure and overlapping sub-problems. ... Optimal substructure means that the solution to a given optimization problem can be obtained by the combination of optimal solutions to its sub-problems.

See the words optimal and optimization?

All DP algorithms guarantee an optimal result. It's a defining characteristic of DP. BLAST doesn't. I'm really surprised that you're attempting to debate this.
Murky3515··on Seam Carving (2018)
BLAST isn't a dynamic programming algorithm. It's not guaranteed to find an optimal solution, unlike a DP algorithm. It has some elements of DP, but that's it.
Murky3515··on Seam Carving (2018)
There aren't many useful applications. People who think otherwise are on par with delusional interviewers that feel compelled to ask problems with DP solutions. The vast majority of us will go our entire careers without needing to solve the Towers of Hanoi or the Egg Drop Puzzle.
Murky3515··on A chemist explains the chemistry behind decaf coffee
TIL about one of the solvents involved, ethyl acetate, and the fact that it is not good for you. How do I know that my local coffee shop's machine is working correctly and provides only safe levels of this solvent?
Murky3515··on Every company should be owned by its employees
So they're too lazy to buy stock when they get paid, but not too lazy to sell stock when they get paid?
Murky3515··on Every company should be owned by its employees
>Every year, those employees get a percentage of their salaries in company stock.

Ok? Anybody can choose to do this if they work at a public company. But what happen if it's mandatory and the stock goes down? Now your labor was stolen at below market rate! Then we will hear "employees compensation should be resilient to market fluctuations."

Murky3515··on Hydrothermal explosion at Yellowstone National Park
The woman in the white shirt, tan shorts only started running because the people behind her started running. She was strolling away from the explosion. Same with green shorts in the foreground. We don't actually see him run, just walking away.

These people have no sense of urgency around danger, or they cannot recognize danger.

Murky3515··on Hydrothermal explosion at Yellowstone National Park
I'm talking about the people in the video who saw what happened, then very casually and slowly turned and strolled away.
Murky3515··on Hydrothermal explosion at Yellowstone National Park
I don't understand the psychology of it either. It's like they think that appearing overly concerned about something potentially dangerous is more embarrassing than being killed by something actually dangerous. That or they have lived such safe and sheltered lives that they cannot identify real danger. I don't have any other explanation.
Murky3515··on Joe Biden stands down as Democratic candidate
Is it really so hard to say "Trump won the debate" without needing to qualify several times how much you hate Trump?

Murky3515··on Bangladesh police given 'shoot-on-sight' orders amid national curfew
It means whatever the men with guns say it means
Murky3515··on Bangladesh police given 'shoot-on-sight' orders amid national curfew
Should this be something that we shut down trade with Bangladesh over? If we continue to sell and buy stuff from a country that is gunning down its people over protests, doesn't that discredit any moral authority that we have? But at the same time, does it worsen the job situation and make the protests worse?
Murky3515··on Are people too flawed, ignorant, and tribal for open societies?
Silly and pointless reductionism. You assign meaning to each slice, but not to the loaf, even though the same logic applies to the "illusion" of a slice? It's turtles all the way down, and the concept of society is as real and as important as any of the other layers.
Murky3515··on Technical Details on Today's Outage
It's not understandable imo. At the very least they should have tests for the loader component that shows it can handle corrupted input. Amateur hour.

Murky3515··on Ask HN: How to finish last 30% of a side project?
"Embrace the suck"

Learn to process the feeling of exhaustion as economically as possible. Meaning, re-frame exhaustion as a normal part of the journey. You really have to push through it, barring mental health concerns, to get stronger and more resilient. You will feel mental exhaustion many times in your life, and it's better to face it early, in less-consequential circumstances, than to try to learn to cope when life is actually bad.

Murky3515··on Don't ask me to embarrass myself
I wonder what happened with those patents. Could a company license them to patent trolls? Otherwise, I don't understand the purpose of spending a lot of resources to come up with a bunch of bs patents.
Murky3515··on There's not that much wealth in the world
I'm advocating for a self-balancing money system that maintains a linear curve of wealth distribution. You can still be richer than your peers, but you can't squeeze the bottom of the distribution.
Murky3515··on There's not that much wealth in the world
The referenced tweet: "Your periodic reminder that the government could seize all of American billionaires’ wealth and it wouldn’t be enough to fund its spending for a single year"[1]

I've had this conversation with the "there shouldn't be billionaires" crowd. Their response was almost always "do it anyways." The existence of people with surplus angers people in a deficit, regardless of if destroying that surplus helps. They want to do it out of anger against the system, not to fix the system.

That said, I don't think fixing the system is impossible. There needs to be a balance between preserving the hierarchy of (theoretical) meritocracy, and not letting too much wealth create a flywheel effect that warps economies. I've done some research of different ideas that could turn the wealth distribution curve from exponential to linear, thereby preserving ordering. Mostly these ideas revolve around each person having their own personal currency, with its own exchange rate which is dependent on different graph connectivity factors. In other words, a rich person's "$10" would be worth much less than a poor person's "$10", in terms of real value. I'd like to do more research into this, but I need help.

Murky3515··on National Guard soldiers training with 'pocket-sized' drones
A practical use for Apple Vision Pro? Soldiers on a breaching team each with headsets, each seeing a real time overlay of X-ray walls and the locations of the people behind them, as tracked by the drones. I hate that I can visualize this so clearly.

Murky3515··on Night owls' cognitive function 'superior' to early risers, study suggests
Working at a company and keeping an early morning routine is absolutely brutal to my productivity. I'm a zombie for about 4/5ths of the day, and I start winding up around end of day. Then all night evening and into the night I'm high performing, only to force myself to sleep so I can wake up early again the next day and repeat.

Yes I've tried melatonin, morning full-spectrum light therapy (incl sunlight), nighttime blue light filters, exercise, restricted night diet, alcohol + caffeine + sugar abstinence, and more that I'm sure I forgot about. Morning productivity just doesn't work for me. The world isn't made for night owl workers.

Murky3515··on A practical introduction to constraint programming using CP-SAT and Python
>the realization that translating constraints to a model (variables, structure etc) is 90% of the work and the most difficult part.

LLMs can help a lot there. I've been wanting to write an LLM => Constraint model adapter that does it for you. It's such low hanging fruit, I wonder if anyone else would benefit from it though.
