> A state-of-the-art facility is now within a factor of two of the theoretical energy minimum, and only 25 percent higher than the realistic minimum for the current reverse osmosis process. In short, it’s going to be tough to squeeze too much more energy out of reverse osmosis, and we’re unlikely to find an alternative method of desalination that will provide a significant boost over that.

> But that doesn’t mean that there are no other ways of getting better output for our energy. The total process of desalination turns out to require three to four times the theoretical minimal energy use, since the salt water must be pumped and pretreated, the membranes maintained, and the resulting brine handled afterwards. Some of these things might be amenable to further improvements, and there has been work put into developing membranes that don’t clog up as easily or better pre-filtering of biological materials.

You're making a mistake assuming that I'm using rhetoric to win elections or build a base.

I actually believe, because there is ample evidence to support it, that this administration's goal is ethnic cleansing via mass deportations, immigration controls, and mass incarceration.

I believe anybody who is ignoring this evidence, and anybody who is able to compartmentalize the grave, mortal danger that members of targeted minority groups now find themselves in as "just politics", actually does not consider those targeted minority groups as fully human.

For whatever reason, you think that's so extreme that I couldn't possibly actually believe it. But I'm being really straightforward. That's what I believe. There's ample evidence to back up those beliefs. I don't care if I alienate some people by saying what I believe is true.

Trump's mass deportation machine is ramping up now. I and thousands of others have trained to intervene directly in deportations, and those networks have already been mobilized to prevent people from being kidnapped from their own homes. That's the base I'm interested in building. And conveying anything less than the full scale of the terror that targeted minority groups are facing, or asking for anything less than the assistance they are calling for, is a mistake.

We don't just throw stuff at prod. Google has a culture of testing and code review, so code review, unit testing and integration tests are the first line of defense. Then we do QA testing, where a lot of problems not caught by tests are found, which then inform us where tests may be lacking. We also roll out to internal dogfood first, given Google's number of
employees this is kind of like a pre-canary.

The point of the canary is it gives you one last real world test where you can limit the damage if anything goes wrong. Without it, you'll have to assume your tests are perfect, and I doubt that's ever achieved in practice in a real environment, except maybe in avionics and space control systems.

Are you talking about the brine? This is trivial if you just put a pipe a few hundred yards out to sea. The concentration is diluted extremely quickly. (The only exception is if your desalination plant is below sea level because then you have to pump the brine up hill, which costs some energy.)

The majority of the US has a murder rate comparable to Canada. The US has particularly extremely tilted murder rates based on location. Relatively small areas with hyper murder rates very substantially skew the numbers. A couple dozen neighborhoods in Chicago for example combine to account for about 2% of all murders in the US (with murder rates 50 to 100 times the national average).

A minimum of 95% of the US population live in areas with murder rates comparable to Canada (around 1.5 to 2 per 100,000 depending on the year). More than 200 million Americans live in areas with murder rates under 2. That's not impressive compared to the nicest parts of Europe, but it is very impressive compared to Latin America and Europe's largest country, Russia.

> Control money to make money. In workforce management, I now realize that controlling payroll data is key. It’s tough to quantify the creation of value otherwise.

My (fuzzy) interpretation: since we weren't integrated with the payroll/hr/accounting systems, we could not prove the efficiency gains our product was meant to bring with hard numbers.

On the one hand I agree that integration with payroll systems is probably critical in this space.

On the other hand, if your product brings a 10% efficiency improvement (which is still huge, not discounting that), it's still going to be hard to prove that, even with access to raw payroll data. Raw payroll data is probably too noisy.
If anything this suggests the opposite. They showed initial promise, raised seed funding, tried to grow, couldn't, so they gracefully wound down before they wasted any more investor money and employee time. This is exactly how things should work in a healthy economy.

There was a article years ago about the Deus Ex team trying to find tune their AI. They found that a dumber AI actually worked better for player enjoyment. Players would frequently think the AI cheated when they got flanked and hasn't seen the enemy move to their flank.

I agree with you, that the US needs to legalize production and sale. However, why has Canada never been wrecked by extremely violent cartels seeking to feed that insatiable drug appetite?

How do you explain nearly all of Latin America having wild murder rates? All of the most dangerous non-war zone countries on earth are in Latin America. And yet that same murder & violent crime problem isn't represented in Canada. What could possibly explain that consistency across ~15 different Latin American nations, except that it's a cultural and institutional problem? Colombia for example has seen dramatic improvements, despite the US demand for drugs increasing in the last 15 years. Or take Venezuela, one of the most dangerous nations, with a truly shocking murder rate, and it has very little to do with the US drug demand. Or take Brazil, a nation of 200 million with a murder rate 7 to 10 times that of the US (with up to half of all murders unreported in official stats), which also doesn't derive its huge murder problems from the US drug demand.

It's far too simplistic to just blame the US for everything.
If there are reasons to complain, _both_ H-1B holders and others are encouraged to complain. But just because some projects are staffed with H-1Bs, there is no indication of foul play. From the link you posted:

Examples of H-1B fraud indicators may include:

* The H-1B worker is not or will not be paid the wage certified on the
Labor Condition Application (LCA).
* There is a wage disparity between H-1B workers and other workers
performing the same or similar duties, particularly to the detriment
of U.S. workers.
* The H-1B worker is not performing the duties specified in the H-1B
petition, including when the duties are at a higher level than the
position description.
* The H-1B worker has less experience than U.S. workers in similar
positions in the same company.
* The H-1B worker is not working in the intended location as certified
on the LCA.
In small print, though. That is the main issue, people see the possible winnings before any odds are considered.

What I meant is that we were not a key link in the workforce lifecycle chain. Without us, people still got paid.

Our V1 timeclock product garnered a lot of interest because it directly led to people getting paid, and it integrated with scheduling to make it easy to tell whether records were correct. I now understand that many more established players, like Kronos, started with payroll as a core feature, then diversified to scheduling.

I've been using Orkin's Goal-Oriented-Action-Planning (GOAP) in my own game development.
Let me tell you an amusing story of how an AI agent outsmarted me, the developer.

So I had set up a test scenario, with an agent that could travel, buy stuff at shops, use axes, cut trees, and so forth. When I ran this test, I had set a goal of procuring timber.

What I expected the agent to do:

1. Go to shop

2. Buy axe

3. Go to forest

4. Cut tree

5. Drop axe

6. Pickup timber.

So I ran my GOAP test, and saw what the agent came up with:

1. Go to forest.

..

When I saw that step 1, I was disappointed, because the agent clearly should not be going to the forest when he has no axe yet.

But then, as a proud parent of my AI, I saw what the agent had actually planned:

1. Go to forest

2. Pick up firewood

3. Go to store

4. Sell firewood

5. Buy axe

6. Go to forest

7. Cut tree

8. Drop axe

9. Pickup timber

Hooray! I simply forget to give my agent money. But GOAP made him smart enough on how to get some money on his own.

I had of course equipped the agent with 'sell' action, and I had placed firewood in the forest, which I promptly had forgotten about when writing a test scenario.

I was so proud of that smart little agent!

Cool stuff, that GOAP!

Yes - Mobius used a lot of the Gurobi API features, including tuning the model before deploying. It's a pretty vanilla use of their library.

I'm more proud of the Autoscheduler algorithm in Julia, which uses a bunch of different models in a kind of Dynamic Programming approach. Check out its README for an explanation:

https://github.com/staffjoy/autoscheduler
Very interesting model that suffers from a couple of things that other data structures solve better IMO. One thing that I don't understand and I guess I have to go back and read the article again, is how the distance from any node X to the arbitrarily selected root M tells me anything about the distance between X and the query term Q. If I live in London and the distance from me to Paris is 50.000 km, and you live in Rome, 70.000 km from Paris, that does not give me enough to calculate the distance between Rome and London.

IMO there is no data structure better suited for a search tree than the doubly-chained character trie [0], as it has the following features:

- small in memory (every word is stored once at the most, but more often less than once)

- traversing and doing exact matching allow you to prune half of the tree at every step

- requires you to calculate the distance only at querying time, not when constructing the tree

- apart from exact and fuzzy matches also support prefix matches (traverse up to the path of the prefix, return all children that are EndOfWords)

- can be represented on disk in a way that makes reading insignificantly slower than reading from memory

- if nodes are lexically sorted when tree is constructed, you have also pretty much solved range queries

[0] https://github.com/kreeben/resin/blob/master/src/Resin/IO/Lc...

The trie is to be the perfect tool for when you find yourself combatting big data. What you find out eventually about all of the cloud offerings from all of the big players that claim they will solve both storing and map/reducing over your data is that you can do the same thing on your laptop, for cheap money, as long as the data is represented in a compressed form that still allow for querying. The trie is a zip file and a search engine in one.

Google's quarterly revenue is roughly $20B[1] - that's $80B per year. I think that it is perfectly plausible that an engineer could achieve a 0.125% increase in yearly revenue. Now, disentangling that from other possible contributing factors, getting the right visibility from management, etc. is distinct from that.

I have no problem believing that MapReduce contributed $XB to Google's revenue over the course of the past 20 years.

I'm curious about "8. Drop axe". Did your system have the constraint that the agent could only hold one thing at a time?

Or was the goal to carry the maximum amount of timber, in which case it's completely sensible to leave the axe in the woods and pick it up again when you return (assuming no other constraints, like competing agents or weather).
