Yah, it's a slight misnomer because both loops are likely closed.

Open/closed loop basically means whether you check the result of an actuation. What we're really talking about is the point at which the loop is closed.

A completely open loop would run the motor for the predicted time.

A simple closed loop would run the motor until the mirror is pointing at the predicted angle, using an encoder to know where the mirror is pointing. The control loop encompasses a mechanical part of the system, but not the end-thing we want controlled. Or put another way, the loop is closed for actuator angle but is not closed for where reflected light goes.

A better closed loop would run the motor until the mirror is reflecting sunlight exactly where we want it-- using magic to know where the light from this mirror is going.

Sorry I think you got me wrong. Wasting time was referring to the mindless chores /errands I need to do every day. Reading physical words from a book is something I can't physically tolerate (but it is not a waste of time). So the best of both worlds is audio books for me - In the portion of time that I believe I'm wasting (chores, commute etc.) I get to read books that I won't otherwise sit down and read. I agree that it might not be as efficient as how a habitual reader reads physical books - but that is not happening to me anyways (I don't sit down and read) - the efficiency gains for me come from the fact that I still get to "read" the books while I'm doing mindless tasks. It actually got me more motivated to run errands (since I don't see them as a time sink now) so I don't procrastinate as much.

Long ago I once attended a conference whose keynote presentation was by a group which was involved in DNA computing. They were talking about using a beaker of solution to compute a Hamiltonian cycle of length, I dunno, let's say 15. I asked how large a beaker would be needed to compute a cycle of length 25. The answer was: about the size of the Pacific Ocean. :-)

His take on this is: " The reading order isn’t that critical, in my view, but it probably improves things to read REVELATION SPACE, REDEMPTION ARK and ABSOLUTION GAP in that sequence. THE PREFECT (AURORA RISING) and ELYSIUM FIRE may be read alone or jointly, but should best be read in the above order. CHASM CITY, as well as the collections DIAMOND DOGS, TURQUOISE DAYS and GALACTIC NORTH, can be read at any point."
I've never understood this argument regarding dating outside of one's ethnic group. The effects of actual racism is one ethnic group benefits at the expense of one or more other groups. What you're describing is something else entirely.

Who's getting harmed when Asian women have a preference for white men when dating? Who cares? To each their own, no? Are you implying there's some maximum percentage of women that can prefer another ethnic group when dating, and anything above that is problematic?

Edit: I should've specified that I'm talking explicitly about their commentary on asian women's dating patterns, not anything else in their comment.
Your perspective doesn't lead to the discovery of the true causal link for sickle cell anemia, though.

It's what leads to us pretending there can't be any unpalatable differences between ethnic groups, clutching to presumptions about maybe the health care system being too racist, and avoiding looking deeper into it because we think we've already decided what the answer is (racism). Meanwhile real people are suffering because they aren't getting treated as effectively as they could.

We don't know what we don't know, so it's impossible to tell how many people are suffering or for what reasons.

If reading books were easy, everyone would do it. Put another wy, reading books is a subtle way to seperating yourself from the masses. Mind you, I'm not suggesting you be elitist about it. Only that books are like using your gym membership; a healthy workout for your brain.

As for what to read, me thinks your over-thinking it. Just read. Read what you like, otherwise you're less likely to stick with the habit.

The whole point is that your models should perform well on data that they haven't seen before. You can't create a hash function for that. Let alone one that works for 100s or 1000s of dimensions.
> linux futex can be implemented through the VDSO (can somebody correct me on this), so that eliminates the worse of the sycall costs.

The semantic of a futex wait is a request to the kernel to put the thread to sleep until another thread issues a signal for the same "key".

The trick is that the key is the address of a 32 bit memory location (provided to the kernel in both the signal and wait syscalls), which is normally the mutex address.

So a process first tries to acquire the mutex as for a normal spin lock (with a CAS, exchange, xadd or whatever work for the specific algorithm) attempting to set the lock bit to 1; if it fails (possibly after spin-trying a few times), it invokes the futex wait. As you can see the syscall is only done in the slow path.

On a futex release, the simple solution is to always invoke futex signal syscall after setting the lock bit to zero[1]. To fast path the relase, a wait bit can be set on the acquire path just before calling futex wait, so on the release path, when setting the lock bit to zero, signal would only be called if the waiter bit was set (and the cleared by together with the lock bit)[2].

As you can see the futex syscall is already the slow path and never need to be onvoked in the uncontented case. In fact the kernel doesn't even need to know about the futex untill the first contention.

[1] futexes are edge triggered, same as condition variables, so a signal will only wakes any thread blocked ona wait that happened-before the signal call. Thus there is a race condition if a lock rrlease and signal happens between the failed acquire attempt and the wait call; to prevent this futex wait as an additional parameter that is the expected value of the memory location: the kernel checks the futex address against this valur and will only if it hasn't changed will put the thread to sleep (this is done atomically).

[2] as there could me multiple waiters, a broadcast is actually needed here which leads to a thundering herd as all waiters will race to acquire the lock. The original futex paper used a wait count instead of just a bit but there are other options.

This entire popsci.com article is utter nonsense. It is nothing but 1950's AMA talking points, and has long been debunked. There are many reasons, but the chief one is this:

All else being equal, the rate of gluconeogenesis (GNG) in the body is constant. It happens all the time, for all people, even type 2 diabetics. It has no correlation whatsoever to protein intake, because the body will break down body tissues if there is not enough protein from other sources.

Therefore, if this article were correct, then NO ONE would be in ketosis.

But in fact, everyone who is in ketosis is also undergoing GNG. In fact, they are undergoing it at a faster rate, and yet, they remain in ketosis. GNG is providing just enough glucose for the handful of body tissues that cannot utilize ketones, and preventing the body from going hypoglycemic. Yet the bulk of the body, metabolically speaking, is using ketones.

And besides the clear scientific reasons stated above, you have the millions of people who do keto, and regularly test their urine to know that they are in ketosis. QED.

Ketosis is not that hard to get into.

See this article, and check the references: https://perfectketo.com/gluconeogenesis/
From my reading of the article, one of the big issues to overcome was cost of CSP vs Photo Voltaic . They're even using smaller flat mirrors that are less sophisticated since per panel costs add up fast. One of the advantages is that this takes 4 cameras across the full plant, not a per panel cost.

That's just my reading of it, not asserting anything myself.

To me (and it seems very much a personal opinion) not having an F-key array on the left - as on the original AT keyboards - was one of the biggest losses made during keyboard evolution. Depends on the software in use of course, but being able to hit a modifier (Ctrl, Shift, Alt) and an F-key without stretching is the reason I still use the old-style layout to this day.

Sorry for the confusing wording. The model is 1.5B. But every 1.5B model is 5.6GB of data. (1,558 million params * sizeof(float32) = 5.6GB)

Quantization is a good idea, but I've had some bad experiences with bfloat16. (We couldn't get loss to decrease beyond a certain point when using bfloat16.) But that might have been an artifact of training. Still, I'd rather not harm the model if possible. It's hard to get a sense of perceptual quality, and I'm not convinced that validation tests are enough to capture the full nuances of GPT-2.

You're right that a single server would do the trick in this case. It's just so much easier to write a notebook with the logic in it than to set up a server, keep track of sessions, make read-eval-print logic, add error handling, etc. I was hoping to throw a couple hundred dollars at the problem of bandwidth hosting rather than spend time making a server.

A server also implies a fixed $300/mo cost, which is pretty expensive. After the initial demo, we'd probably end up turning the server off. I dislike the idea of the demo breaking after a month or two.

More opportunities != being ahead.

Given two research labs, with one having a bit better equipment, while the other having a more proven history of publishing innovative research, it would be disingenuous to say that the better equipped lab is ahead until they have actually produced some research that puts them ahead. It might help them gain lead, but it also might result in nothing. Better equipment is just one of many components that affect the chances of success. Until that lead is acquired, I don't really think it would be appropriate to say that they had done so.

Note: the lab with a history of published innovative research in my analogy isn't supposed to represent the US or any country in specific. This was just an example to better illustrate the point I was making. The only thing that should matter for whether someone is ahead or not in this situation is the actual proof of being ahead, not "the opportunities that could lead to them being ahead". Otherwise, we should also start immediately trusting all those articles that pop up once every few months about how some random city is "about to become the next Silicon Valley, here are the reasons why".

In which case is it 3.6x higher?

The most common drug people get arrested for is marijuana, and the difference in use (even by your chosen metric) is nowhere near 3.6x.

The only drug where you can make an argument even approaching 3.6x is crack, which is a relatively small percentage of arrests.

I also note you omitted the "stimulant" category (which in the 2011 dataset covered methamphetamine).

Because AOT compilation can be used to construct a system which is functional without the compiler, but runtime compilation requires it at runtime. The difference is plainly obvious.
The top comment opens up the concept of latency versus throughput. My interpretation is that this experiment is demonstrating that optimizing only for latency has consequences elsewhere in the system. Which is not surprising at all, but then again I spend a lot of time explaining unsurprising things.

I remember a sort of sea change in my thinking on technical books during a period where I tended to keep them at work instead of at home. I noticed a curious pattern in which ones were getting borrowed and by whom. Reading material isn't only useful if it has something new to me in it. It's also useful if it presents information I already know and agree with, in a convenient format. Possibly more useful, in fact.

Why should blame be tied to compensation?

Compensation tends to be tied to perceived impact. The perceived impact of a manager with 10 reports who are all focused and delivering individually is much higher than the impact of a manager with the same number of reports where half the team meets few of their goals.

The first manager is ultimately going to be seen as more effective and will get larger bonuses and will be more frequently promoted and ultimately grow the scope of what they own. That they happen to get paid more than individuals reporting to them is entirely appropriate based on their overall impact.

That managers sometimes blame the people on their team for the failure of the team is bad management (and worse if the people above them blindly accept that) but I don’t think you can assign all blame to a manager just because they happen to be the manager and certainly not because of their relative pay.
An equally disappointing take for me is the whole "the system is to blame" angle where nobody is ever responsible for their own actions. i.e. "free will doesn't exist; you would have made the exact same decision had you been subject to the same pressures"

Yes, "the system" plays a role, but it's dangerous to make it the sole scapegoat. I like the idea of mentorship because it aims to change individuals, not just blame the system.

Black boys could break free from the cycle, if they had the knowledge and know how. And they can get that knowledge and know how by following the examples of mentors who are not trapped.
I think it's very poorly articulated.

It may be more accurate to say that the net result of hundreds of year of policy has conspired to concentrate and grow aspects of culture that create net, lasting disadvantages.

It's likely not enough to fix the discrimination itself now, or even to provide an economic hand up. Maybe some things that were adaptive / natural reactions under discrimination are now maladaptive and harmful.

Worse, the maladaptive behavior helps perpetuate the discrimination and bias.
Fair enough, for sure, but the statistic doesn’t really get at that point directly. It’d be better to say “50% fewer non-agricultural birds were alive in 2019 than in 2018” (or whatever the stat is) if that’s the point they wish to make.
It is problematic to asians as a whole. It's pretty obvious when asians discriminate their own race and view white people as superior. There's really no argument for you here.

Definitely not problematic to white males who are dating asian females though.

Honestly, among white guys it manifests itself as Asian women being "easier" and there's nothing wrong or racist for taking advantage of it, but it definitely won't appear to be a problem from your perspective even though something deeply wrong is happening.
> GlacierMD was explicitly an attempt to filter, aggregate and make available high-quality health-care information (i.e. improve the quality of the signal, which is necessary for efficient market functioning), and it did not find a value proposition in the market.

Except it doesn't -- what GlacierMD was trying to do is something that's currently done by humans at scale. Which he would have known if he understood the market better. This is a centralized function that is performed much higher up the chain and ends up in clinician / patient hands in the form of clinical guidelines.

This is maybe a useful tool for researchers to be used as one input in the development of clinical guidelines. But the functionality it delivers can be done manually (and will continue to be for liability reasons). In this case, the market worked. The author should be thankful he was able to get out of it only $40k in the hole.
From the architecture PoV it is exactly same thing if you think of it as implemented by LL/SC pair. This is how this is presented in most of literature and university courses.

> It turns out the amount of time you spent getting the tickets is irrelevant. If you wouldn’t be willing to PAY $500 for these tickets (and you weren’t, or you would have) then you should be willing to sell them for $500.

This example has nothing to do with sunk costs and everything to do with WTP vs. WTA. Some people -- like the author, apparently -- think they are the same. Those people are wrong.

Ask yourself - gun to your head, right now, how much money would you offer to pay the man threatening you right now for him to go away? And what is the minimum you would accept from him, if offered, to let him blow your brains out? Chances are, the amount you would be willing to accept for X is much much higher than the amount you would be willing to pay for ~X.

Or, from a different approach, if your willingness to pay to go to the event and your willingness to accept to not go to an event were identical, then going or not-going would have to be a wash. That's obviously not true, or you wouldn't have put so much effort into going.
A general rule of thumb is the older the written word, more valuable it is. Accordingly, the books that have been around for a while and are still well-known they give highest value from the time you invest in reading them. The content on Internet is mostly about current events and it lacks the depth that old books have. News or opinions on current events will most likely become irrelevant and obsolete. The stuff worth reading will survive the test of time and you can read it in future. Staying up-to-date with current happenings is overrated, because most of those things don't happen our daily life. Therefore best invest your time reading meaningful books.
