https://fullstackdeeplearning.com/ and https://course.fast.ai/ seem to be what you're looking for.

Both only cover the math as it becomes relevant. I am working through fast.ai's book right now and find its pragmatic approach to DL pretty agreeable to just getting models hosted and out the door. I watched the lectures before hand, and there are several Jupyter notebooks and examples on how to get models deployed ASAP with clunky interfaces, which also might be of interest to you.
If it was just a matter of house prices, why isn't California's homelessness solved by cheaper homes in Fresno or other parts of the state? I can't help but feel there's more to it than cheaper housing.
CDC published how lethal it was in March 2020 and that it was basically identical to flu in terms of expected casualties.

I knew earlier than that. I considered buying a hazmat suit but realised it was a meme and settled for buying some masks etc in early 2020.
> Except that the thought experiment is completely divoreced from the way AI actually works.

Is it? I don't think so. In my opinion, it's important to remember that AI intelligence is not the same as human intelligence. So, just because I "think" doesn't mean AI "thinks" or is "bounded to think" the exact same way. AI could "think" like me, but also it can (and does) diverge in its reasoning paths. AI is AI intelligent, not just human intelligent.

> How did the AI learn that it could prevent human override by killing the human operator? How did it then learn to destroy the COMMS tower so that it wouldn't be penalized for killing the operator.

This could be a simple situation where all input agents are included in the event space and therefore the model performs active calculations at runtime to optimize winningness. If the COMMS tower is too noisy, where noise is considered hard to understand or conflicting messages, then it (or the human communicators inside it) could be viewed as inefficient, and eligible for termination. It is considered one viable path of exploration towards successful goal completion. Additionally, because AI is supposed to kill "some humans" it is possible that AI decides to eliminate the boundary between "good" and "bad" humans (however that is delineated) at runtime, effectively lumping all humans into one category: killable.

Regarding the COMMS tower, again this goes back to what objects are included in the event space, human classification (and reclassification) and (re-)ranking optimization tasks executed at runtime, and reward distribution as it pertains to goal achievement. If the ultimate goal is discovered to be achievable, the penalty doesn't matter, because there is a clear and executable path towards goal completion. And that is the supreme reward state-- successful goal completion.

> Why was human feedback even part of AI training simulation? Why did the reward function in training include logic that says 'if the simulated comms tower is destroyed, do not penalize friendly fire'?

This could be a simple "human in the loop" requirement. Additionally, if AI has access to auditory input streams, it can decide what signals are important regardless of if speech is directed toward it.

As for the reward function, AI can decide the presumed penalty is not that severe, so "explore" and see what happens (e.g., do I accomplish my goal?). If the goal is accomplished, it doesn't matter the penalty, because goal completion is the desired end state.

I will ask you the same, why do humans engage in friendly fire? And why is friendly fire not penalized?

> We can talk about hypothetical AGI all we want, but that has nothing to do with what us currently called "AI"...

On the contrary, advanced AI/AGI will be able to recall. Why? It will have access to the data (e.g., the news articles, the classified and unclassified docs, the humans providing opinions about what happened, the input specifications and outcomes, the weights). Again, I will caution that AI is not human; it is not limited to be forever fallible, like humans.
Yeah; its really confusing but javascript - for legacy reasons - treats strings as "arrays of UCS2 items". But javascript also implements iterator on strings which iterate through strings in unicode codepoints. Thats why "of" loops work differently from "in" loops. (for-of in javascript uses Symbol.iterator). That also means you can pull a string apart into an array of unicode codepoints using [...somestring].

The advantages of the paid Saas to me would be:

1. Time. If it can be deployed to accessed much faster, or changed/updated faster than I can myself, it's worth the cost

2. Support. SAAS offerings usually have support that would reduce the need to debug everything myself

3. Convenience: The SAAS may be more easily accessible via the cloud portal, wouldn't require that I store and maintain things myself, and overall reduces the overhead in that regard.
Literally nearly all of them. PTO accrual is the most common form of PTO granted; you accrue a certain number of PTO hours for every week you work, and your maximum PTO per year changes with your tenure, starting at, say, 10 days per year and maxing out at, say, 25 days per year, for example.

You can usually also roll them over to the next year up to some amount.
This is incredible news to read. I am now even more optimistic about the future considering this and the progress in renewables (in market) and fusion (in meaningful achievement) over the last 15 years.
It's not that funny.

While there may be millions of useless attempts, it only takes 1 to get through.

Of course SSH has a great option in key / certificate auth. So if that's enforced it's not such a big deal. Many other systems don't (at least not until we finally implement Passkeys everywhere).
Finland also has a very robust social safety network unlike California/US. Homelessness is usually a symptom of something else. Addiction, mental health issues, financial crisis of some sort, etc. Most of these are escapeable given the right support. But once you pile them all on with no escape - well then you have market street.

If you don’t fix any of the other issues then you just end up throwing money in a bottomless pit on housing
> Are these human brain cells?

A goal of the paper is to produce a system that can be used by researchers to experiment on neurons from different sources. It mentions its use of a few different cell lines, from mice and humans both, so at least some DishBrain runs used human cells. The human cells were from cell line ATCC PCS-201-010, which are stem cells derived from the dermal cells of a newborn baby's foreskin. The authors coaxed those stem cells to differentiate into neurons.

> how many do you have to grow before it becomes an ethics issue

The paper says they used methods to "achieve a dorsal forebrain patterning" and plated 10^6 cells on each electrode array used for testing (about 5x the brain cells of a mosquito, or a tenth of the cells in a mouse brain). Note that I have no idea if all million of those cells survived until the experiments were carried out, or if they were all actually used in each "brain" (maybe they were segmented out?)

I think the ethical issues are going to depend largely on how much the structure of the neurons affects awareness. A pile of 10 million random mouse neurons on a plate probably doesn't have anywhere near the same value of experience that a 10 million neuron actual mouse brain has. But I'd say if you're okay with experimenting on mice, 1 million neurons in a petri dish is very ethically safe in comparison. Agreed that we're starting to get to the point where it's more questionable though.
Is that what the author is implying? That certainly wasn’t my takeaway. If that was the author’s intended message, I’d certainly agree it’s not a good one. But I doubt that was the intended message, to be honest. One population being more significantly impacted by something does not imply that other populations are not also meaningfully impacted.
Ask HN: Real-life, ridiculous security incidents?
I was reading some of the comments in this submission about attackers trying to brute force ssh credentials.

https://news.ycombinator.com/item?id=36169954

In the comments fellow HN'ers were discussing the possibilities of XSS attacks using the password.

This had me thinking, have there actually been such successful attacks in your experience and how regular are they? Think of some kind of ridiculous XSS using <script>...</script> or anything similar.

Are these still successfully happening in 2023?
(I live in Brazil)

Since, according to the article, wheat should be planted on already existing crops, I don't think it will be a big issue in the near future. However, soybeans are already a major cause of deforestation, especially in the Midwest, and this extra productivity may boost these activities.

I'm not an expert, but working with multiple crops in the same year can also further deplete soil resources, decreasing the overall productivity and increasing deforestation.

Brazilian politics is extremely messy right now, and it's hard to tell how we're going to face environmental issues in the near future. The recently-elected president has a strong environmentalist agenda, but is fighting with the Congress and may lose support for pushing forward such legislation.
Mine didn't really have a choice, unfortunately. But I guess it was technically a "free" trip across the ocean.
Coinbase Says AI Represents ‘Important Opportunity’ for Crypto
Not really. A lot of these bots are super duper dumb and continue slamming your server with handshake attempts even if password auth isn't even turned on. Every handshake is wasted CPU resources (and asymmetric crypto isn't cheap). It also makes it harder to see real dangers in the logs.
You're making a conjecture between two separate things. The statement regarding revenue being down 43% is not related to the deficit statement from Russia.
> However, it does not support keyboard shortcuts for navigating and selecting an application!

This is the thing that is most frustrating to me about MacOS—keyboard support is clearly a second class citizen.

It seems like you're supposed to use the trackpad for everything, but when I'm docked I want to use an external keyboard and mouse. The only mouse that supports the trackpad controls that Mac assumes are available is the magic mouse, which my company helpfully provided, but the ergonomics on that mouse are terrible. It's this tiny little flat slab that offers nothing in the way of support.

If I could figure out how to control everything with the keyboard I'd swap that mouse out for an ergonomic one, but virtual workspace management with pure keyboard seems to be impossible even with Rectangle installed.
As much as I've been deeply unsatisfied with a lot of SCOTUS decisions in the past few years, I have to agree with you completely that it is the legislative branch which "should" have resolved nearly all the high-profile (and possibly even medium-profile) cases that have been brought to the court, by passing actual laws. Should we have (abortion, vote by mail,
immigration, etc etc)? Yes the answers are controversial, but this stuff is too important to leave to a committee of unelected judges to speculate about what long-dead founding fathers wanted. We have current, real-life representatives, in theory, who could pass laws reflecting what we want, in theory. In reality the legislative branch is what's very broken.
I'd be happier if more socialists actually read Marx. However, to your point. Marx thought that once our production ramped up enough, we could have everything we needed and overthrow our capital demons. He also thought that there was a ceiling to production innovation and that profits would eventually dry up due to competition.

But its been 150 years and none of that is true, we're still getting better at doing things, and human appetite for consumption hasn't really slowed down. Some part of that is hierarchical, some people just want to be better than others and so their consumption is relative. This is where a lot of artificial scarcity is manufactured. But we still continue to solve very real problems, much of which is fueled by a capitalism.
Ditto. What a terrible statement to open with. Not instilling me with a lot of confidence. Shannon's Maxim states that the enemy knows the system...

I am not serious, completely. But you called it a dumpster for the underclass (not judging either way).

But it points to an irony when you’re there, going to a meeting at the Transamerica pyramid or walking past the headquarters of Salesforce, or having a michelin starred meal, then walking down the street and a guy in an alley has a knife.

It's impossible they will brute force your key if you have a decent length.

While I'm sure it is possible for some (mainly government) actors to brute force keys, I'm also sure these do not include the same low-hanging-fruit vandals blasting brute force attacks. And I'm also pretty sure you're not one of the select targets of these highly advanced actors.

A vulnerability in sshd is indeed possible and happens once in a while. Fail2Ban won't stop this though because a known exploit will let them through on the first attempt.

I personally view fail2ban more as nuisance control when it comes to SSH with password auth disabled. Minimizing the log crap, the wasted CPU resources by the failed handshakes. It's not really a security protection in that scenario. In other cases (e.g. web logins where passwords must be used) it of course is.
Literally the Scrooge solution "are there no prisons?"
We should assume that what someone says is unrelated to what they meant? That's an interesting viewpoint. I have to guess at your meaning since I can't fixate on what you're saying, but I think you mean that language is meaningless?

> BB's really are a problem to modern physics/cosmology

No, they really aren't. They have never been observed. They are incompatible with present-day observations, and so as far as we can tell probably they have never existed in the history of our observable universe. They thus are a diagnostic on approaches to cosmology which have conditions favourable to BBs in approximately present times (or in the past), essentially killing any theory that does not suppress them.

They also imperil some theories of the far future which rely on fluctuation theory to produce a whole new universe (some decay-of-false-vacuum models, for instance). Very short lived and spatially tiny low-entropy configurations are enormously enormously ENORMOUSLY more likely than large low-entropy configuration that persist. Boltzmann brains describe a very short lived (much less than seconds) fluctuation into a very low entropy configuration, and are thus much more likely than a fluctuation producing Boltzmann being who can survive in outer space for at least minutes, let alone a galaxy in which a thinking being evolved and personally experienced many years of life, or a universe with many such galaxies.

This also means that because of the scale and history of the universe that we have direct experience of, one cannot safely draw a physical-theory parallel between our universe's projected high-entropy far future and our low-entropy past more distant than the dense low-entropy phases about which we have evidence (from the surface of last scattering to baryon species and abundances, ...).

Multiverses are not needed in this analysis, and don't really help one way or another. If you figure out how some other space in a multiverse configuration interacts with ours (and prove it experimentally or observationally), you will have mostly just changed our understanding of our universe and its (quasi-)local physics, particularly thermodynamics.

Does that come from somewhere in the paper? I'm seeing "10^6 cells plated onto each MEA" and trying to determine if that's the size of each "DishBrain" or if the number is pared down before actual tests are carried out.
I was in CDG airport in the 90s, shortly after they introduced a smoking ban, and gasping for a fag. So I went over to a check-in desk and asked the woman where the nearest smoking area was. She gave me a Gallic shrug and gestured to indicate the entire airport.

u can give every homeless person one billion dollars each, and 99% of them will squander it on drugs. Homelessness is a not a problem, its a symptom of a bigger problem. It's usually the result of years of bad choices and drug abuse turning into permanent mental disability. Giving them all the money in the world is not going to fix the bad choices that result in their situation.

Stanford has renamed campus spaces to stop honoring David Starr Jordan because of his eugenics advocacy and other bigoted views:

https://news.stanford.edu/2020/10/07/jordan-agassiz/

You can read the report on him, commissioned and published by Stanford, that went into making this decision:

"Reports Of The Advisory Committee On Renaming Jordan Hall And Removing The Statue Of Louis Agassiz"

https://campusnames.stanford.edu/wp-content/uploads/sites/14...

Stanford has already acknowledged the ugly views of its founder and stopped honoring him. Posting a battle-cry like this on a story that is only tangentially about the history of Stanford seems likely to hijack discussion.
I think the real argument here is that it wasn't just some Joe Schmoe making the move. But the people we're talking about here are below Joe.

Moving may be easier in that it doesn't have a high risk of death, but much harder in actually surviving at your destination. You don't just grab a plot of land and start building your own house these days. America did that hundreds of years ago and charges for it now. How are you paying a security deposit in another state on minimum wage, let alone the travel and job seeking?
I literally gave you a Wikipedia list of other concerns, "natural monopolies, pollution rights, and control of the commons, including title of ownership for natural resources and other contrived privileges (e.g. intellectual property)", the Georgist word land abstracts away, telling you the land of today is data, and the land of tomorrow will be neural models. Complex issues often have solutions in other places; houselessness will indeed not be solved by putting some people in some houses.

I'm sure some actual Brazilians will comment since many are active on HN.

I remember being asked in elementary school to help "buy a piece of the Amazon to stop it from being cut down". I mentioned this years later to some Brazilian friends, and they found it amazing, saying first that it almost certainly wasn't a specific plot of land, and second that enforcement of property rights and anti-poaching laws in spread-out rural areas has been spotty, and also hindered by violence and corruption.

So I guess it's a thorny question, if someone in Brazil accepts such a subsidy, how that ultimately translates into physically stopping people from making illicit uses of Amazon lands.

Edit: In theory, stopping an illicit farm (which takes time to grow and has to be tended and harvested) would be easier than stopping someone with a pickup truck and chainsaw from just grabbing a bunch of trees for lumber. On the other hand, the U.S. has spent tons of money trying to eradicate poor people's coca farms in the Andes and it doesn't seem to have had the level of success the government hoped for (https://en.wikipedia.org/wiki/Coca_eradication).

Meanwhile, some people are apparently still maintaining wildcat marijuana farms on U.S. Federal lands. Wheat farms aren't as profitable as coca or marijuana, but even suppressing certain kinds of farms in remote enough areas seems like it can be non-trivial!
The reports of recently intercepted balloons sounded like balloons but weren’t identified as such. It is possible that was because they didn’t want to admit they shot down little balloons. Or maybe pilots didn’t recognize them without seeing the tiny payload from a quick pass. But there was lots of speculation, including from in government, that they were mysterious.

Most UFOs aren’t balloons, but we have recent examples of balloons being identified as UFOs.

Compared to previous years. The 2022–2024 Immigration
Levels Plan continues to build on the 2021–2023 Immigration Levels Plan with higher admissions targets to address pandemic related shortfalls. As outlined in the 2022–2024 Immigration Levels Plan, Canada aims to welcome from 360,000 to 445,000 new permanent residents in 2022, from 380,000 to 465,000 in 2023, and 390,000 to 475,000 in 2024. The 2022–2024 Immigration Levels Plan includes targets that build on the ambitious targets set in previous years. In 2022–23, it is anticipated that as border restrictions gradually ease and travel levels regain momentum, clients residing overseas will increasingly be able to land in Canada and be processed, which will support efforts to meet the objectives of the 2022–2024 Immigration Levels Plan. Furthermore, the Department’s efforts to reduce overall inventories of applications, including paper-based permanent resident inventories, as well as further digitization of services, will contribute to achieving the ambitious levels targets set out in the 2022–2024 Immigration Levels Plan. The Department will continue to monitor immigration levels and work with other federal departments and agencies to continue protecting the health and safety of Canadians as newcomers are welcomed to Canada.

Very interesting document.
