If I can distill my objection to the pure capability model: there are two different statements of the capability manifesto, one strong and one weak.

The weak capability position is that it should be possible to construct an opaque combination of designator and authority, ie, a capability. The strong capability position is that designator and authority must always follow the same path.

So in the "pure capability model," you are actually subtracting a feature from the system. Now, of course, it's often the case that subtracting a feature makes a system better. But one needs to be really clear about confusing this with the positive virtues of just having capabilities.

Also, while I agree that capabilities are really great (Arvo has a somewhat capability-like internal communication model), it's important to point out that (a) capability vs. identity is a duality; and (b) it's cheating to compare a good capability system to a bad identity system.

For (a), note that identity systems can implement capability features like delegation and revocation; they just have to do it actively rather than passively. If I am willing to act as your deputy, I can delegate my power to act to you. Or some restricted subset thereof. Tell me what to do and I'll do it.

For (b), if you put a decent capability system next to the Internet, a network whose identity model is a burning-tire dumpster fire. If your identity system actually works and makes sense, competing is harder for the capability design.

I do think Urbit should have some kind of capability model. However, this has the feel of a 2.0 or even 3.0 feature. I hate to solve a problem until it is actually in my way. I feel we have come nowhere near the limits of the common case. A simple map from identity to privilege is certainly that.

And while capability UIs may be doable, identity UIs are trivial. This would not be the first case of humans being funky, hence screwing up our elegant architectural logic.

If you have a system software project and it can advance without being lashed to a company, definitely do it that way! It's always a poor fit -- they have to succeed on different timelines.

One thing I know: once we all have personal servers, today's cloud will look pretty lame in retrospect...
- Do we even have a way of measuring serotonin levels in a live human (as opposed to a dead lab rat[1])? Remember, we're trying to measure serotonin levels in the synapses between neurons in the brain (serotonin is a neurotransmitter, so its levels anywhere else in the body probably wouldn't matter), so you can't just draw someone's blood and test it. If the measurement involves drilling a hole through someone's skull, you can be sure it hasn't been done on lots of people (no ethics board would allow that experiment, even if you could find non-depressed people to volunteer for it). If it requires injecting people with radioactively tagged serotonin precursors and scanning their brains, it probably hasn't been done on a lot of asymptomatic people (risky and expensive).

- Assuming we can measure serotonin levels in humans, how do we determine whether someone's level is "low"? Does "low" mean "low compared to the average of non-depressed people"? Does it mean "low compared to the level the patient had before they became depressed" (if so, how would we know their baseline levels)? Levels of many chemicals (hormones, glucose, sodium, etc.) vary significantly between "normal" individuals.

[1] We can't talk to a rat to determine whether it's depressed. We can only observe certain aspects of its behavior, like appetite and activity levels, which we assume are proxies for depression, but could be due to unknown factors. We don't really know if rats have evolved to become depressed the way people do.

Given that people who memorize sanskrit hymns typically come from a single caste (with limited intermarriage between castes), the control should just include the members of that caste (but who don't memorize hymns) - to account for genetic effects. And as another commenter pointed out, this doesn't prove anything about Sanksrit. To prove something like that, the authors should have compared brain sizes with people who memorize other non-sanskrit texts.
We've achieved continuous war. Counter-insurgency is like a pushing contest in a valley. If the insurgents start to win, they have to control territory, which means visibility and concentration. Then they're vulnerable to heavy weapons. If the counter-insurgents start to win, the insurgency goes underground and is too distributed to attack effectively. Neither side can force a decision.

Thanks for link. But the selection seemed very odd. I wondered how they got that list from HN. The site says

All links to Amazon, Safaribooks and O'Reilly get extracted once a week from Hacker News posts, make sure they are indeed books and then rank them based on how often they are mentioned and the karma of the user.

Ahh. I guess that's it - people don't bother giving Amazon/other links for well-known books. Or sometimes the book has its own website.

Also, that site makes money by linking to Amazon. That seems a bit dodgy to me!

Hmm is it really that hard to extract book titles that aren't links to Amazon/publishers? C'mon hackers! :-)
IIRC, the current consensus among the psychiatric community is that SSRIs do work but no one actually knows what mechanism could explain their effectiveness. The one thing that is known for sure is that it doesn't come down to simply high vs low levels of serotonin because while SSRI treatment immediately raise serotonin levels the therapeutic effect takes some time to "kick in".

I also recall reading that SSRIs have been found to be more helpful against anxiety than depression.

I just recently learned that Sanskrit was the first language to have its grammar formally specified. Pāṇini in the 4th century BCE wrote down the complete one. I couldn't find a good translation of it online. I suppose translating a grammar written in the language itself is tough.

I was curious because I want to know how much of BNF grammar functionality is represented in it. Perhaps BNF is just a rediscovering/reformatting of the Sanskrit grammar?

Tenured professor of psychiatry here. I'll give you the summary of research on depression:

1. Emotional state is like blood pressure. It's a continuously varying thing. There is no discrete depressive disease state, just an extreme end of a continuum.

2. Just like blood pressure, though, very high blood pressure (or low) represents an illness state, a potentially very serious one. The etiology is a different matter. It may be due to sociocultural processes, or existential threat, or genetics, or neurological insults, or all of the above, each in some measure.

3. When we talk about "depression," it's usually a shorthand for a broader set of problems, related to lack of well-being, malaise, despair, sadness, anxiety, fear, and so forth.

4. The particular cocktail of emotions for each person is different though.

5. The best meta-analytic evidence suggests that antidepressants work, but not nearly as well for people as we were led to believe, and there's huge publication biases. Some drugs might not work at all. Some drugs work for some people; those same drugs might not work for other people at all.

6. Serotonin per se probably has nothing to do with the effect of antidepressants.

7. Psychotherapy works as well or as poorly as drugs on average, with some of the same publication biases. This is considered against many different types of controls, including placebo controls and various types of behavioral controls. Being wait-listed is the worst intervention of all, though.

8. Different psychotherapies do not differ in efficacy on average. The superiority of cognitive-behavioral therapy, etc. is a myth. Different therapies might differ for particular individuals, though, and there are some basic ingredients that seem to be necessary for efficacious therapy. The effect of therapist dwarfs the type of therapy (that is, some therapists are really really good, and others are less good, and that is much more important to outcome than type of therapy per se).

9. The best outcomes are generally therapy and drugs in combination, and if one thing doesn't work, trying different things will often work eventually.

The recent history ("recent" being the last 30-40 years) of psychiatry and clinical psychology is dominated by economically and politically-driven reductionism and oversimplification, within the realms of therapy as well as pharmacology. A lot of these dynamics are driven by a desire to present as rigorously scientific, wrapping ones' selves in banners of other disciplines. The problem with this is behavioral science is its own thing; it resembles other disciplines in some ways, but not in others (much like every other domain of science).

That's nonsense.

Netflix using bandwidth doesn't harm anything. IPSs are free to offer users all the bandwidth they have available. Running out of bandwidth is not harmful to anyone.

Putting pressure on the network is the only way infrastructure gets updated. We haven't reached the point where every user has the highest reasonable amount of bandwidth. I posit that we never will. ISPs want you to believe we have so you will believe people are using the internet "wrong" when the real problem is that ISPs don't want to invest in infrastructure. I won't hesitate to call them out in their BS.
I wasn't telling you anything you experienced was false. I was simply pointing out that the stressful period you mentioned would definitely be a factor causing depression.

>Just looking at your final example, I can't understand how you can say that is unsafe

Let me change the example a bit. Say we have two locks aL and bL, that we must always acquire in the order aL first and then bL.

Following the rule, say we write code like this:

import java.util.concurrent.locks.ReentrantLock;
class X {
private static ReentrantLock aL = new ReentrantLock();
private static ReentrantLock bL = new ReentrantLock();
static int x = 0;
static int c = 0;
static public void main(String[] args) {
for(aL.lock(); c < 100; c++) {
synchronized(bL) {
x = x + 0x42;
}
}
aL.unlock();
}
}

If I understood it right, the blog post was asking a question whether JVM can transform this to:

import java.util.concurrent.locks.ReentrantLock;
class X {
private static ReentrantLock aL = new ReentrantLock();
private static ReentrantLock bL = new ReentrantLock();
static int x = 0;
static int c = 0;
static public void main(String[] args) {
synchronized(bL) {
for(aL.lock(); c < 100; c++) {
x = x + 0x42;
}
aL.unlock();
} // end synnchronized
}
}

Since the locks are now acquired in a different order, does that not qualify as observable behavior?

> You just need a sufficiently large group of academics, programmers, developers etc to identify issues.

I don't attribute any sort of sainthood or trustability to academics over other segments of society. It's certainly not clear that programmers are especially qualified to craft public policy. Again, instead of one group of elites that can understand what's going on you're substituting another.

Look, with Open Source software, programmers are mostly the consumers of that open source software. The customers of that software can more or less switch and aren't forced to use it at the barrel of a gun (and in the cases where big companies DO have monopoly power, the fact that they use Open Source software doesn't really stop them from exercising it in ways that are clearly for their benefit but less clearly for the benefit of their users). But if you're saying that software is now going to determine who can be arrested and who can go free, how long prison sentences will be or who can go on welfare or receive public money, there is HUGE incentive to game the system. Right now I might find Academics trustworthy because they don't get a huge financial benefit depending on the outcome of their research. But if public policy is controlled by software the incentives to cheat are huge. Now you can say they'll patrol each other, but that just means the incentive will be to collude collectively, as an entire group, for their own benefit against society at large.
That to me seems like the coolest possibility.

Again, I repeat my question: if we were lower in the food web, wouldn't we still depend on branches of the food web lower than you? That seems to be true regardless of where you are on the food web. In fact, wouldn't we be more susceptible to harm if we had fewer possible sources of food? One would expect that the fewer alternatives we have, the worse off we would be, right?

Run root applications on Wayland desktop
The most common mistake I make while using make ( no pun intended ) is to invoke the command from a child directory where no Makefile is present.

I wrote gmake to solve that pain point.

Why not simply use the -C flag that is built into make ?

make provides a -C flag which accepts the path to the make file but that defeats the purpose as it is more effort/time consuming to type it out.

Using your bash history does reduce the pain of repeating the -C flag, however, that fails when you have to switch amongst different repos/makefiles quite frequently.

Infact, using gmake will make it possible to use your bash history more consistently as gmake test or gmake build are common enough and the -C flag is abstracted away

That first video is awesome, thank you! As for the second type of postmodern-art-hater you quote, do you ever think that someone can be making a valid point about the valuelessness and meaninglessness of someone's creations that have been chosen by another person to be displayed in a gallery? Is everyone who draws or paints a picture an artist? I myself see much of postmodern art as "meta-art," or a work of "art commentary," a statement about what people can be made to see as "art" (such as: excrement on a floor, a pile of rocks, or a piece of paper that says "This is art") but it's not art. I'd say that Duchamp's urinal is meta-art.

This is because our politicians don’t even read they law they passed or objected. A Democrat will always object a Republican law and vise versa. They will support their own party’s law

If politicians have to do their own tax return, I can guarantee you the tax code will be a lot simpler than the 70,000 pages we have.
