Please don't say "huge" when talking about your traffic. That is misleading.

The appropriate word to describe 8 requests/s is "nothing". Health checks and monitoring could do that much by themselves when there are no users.
200 requests/s is a very small site.

To give you some point of comparison: 200 HTTP requests/s could be processed by a software load balancer (usual pick: HAProxy) on a t2.nano and it wouldn't break a sweat, ever.
It might need a micro if it's HTTPS :D (that's likely to be generous).

To be fair, I hardly expect any performance issues from the load balancer before 1000 requests/s. The load is too negligible (unless everyone is streaming HD videos).

All the answers about scaling "ELB" are nonsense. There is no scale in this specific case. The "huge" peak being referred to would hardly consume 5% of a single core to be balanced.

I used to criticize ELB a lot and avoid them at all cost. So do many other people on the internet. But at your scale, all our hatred is irrelevant, you should be way too small to encounter any issues.

N.B. Maybe I'm wrong and ELB have gotten so buggy and terrible that they are now unable to process even little traffic without issues... but I don't think that's the case.

I keep watching older TV shows that aired when I was in the military and they keep using the term "War on Terror", which frankly, is something I'd never directly heard in the military (only from politicians) and it's surprising to me that anyone would say such a thing without reactively slapping themselves for gleefully eating up such confusion-inducing propaganda.

I think some people just like talking like that.
Very few companies provide feedback on interviews because it opens them up to legal liability. In general when feedback is given it is because there is a specific singular reason they rejected the applicant. That's pretty rare, most companies will be choosing between multiple qualified applicants and will be deciding on based on secondary factors including salary requested, likelihood that the applicant will leave after x amount of time, trainability, and culture fit.
The latter. The tau's lifetime is 10^-13 s. The muon lifetime is 10^-6 s, and the experiment is already hard.
Anecdata: from my travels in indigenous areas in various parts of the world, and from my experience with organic farmers in the US (not really comparable I know), I would say that the variance is high. With modern medicine and transportation (to bring some produce and things such as handicrafts to market for supplementary income) in some climates and soils the life of subsistence farmers is not at all terrible. Many involved make materially more rewarding choices when they can, but (and again I know this is not really comparable) I know successful PhD scientists (one a biologist and another a physicist) who gave it all up and became organic farmers in the mountains in the SE U.S. and are happy for the choice they made.
1) It doesn't make sense that both Verizon and all its possible competitors (including anyone not in the wireless business) would leave FTTP profits on the table merely because they can make more on wireless.

2) I thought one point of the article is that wireless bandwidth is limited. They can only get so many GB in given frequency, and the 5G requires a higher number of cell sites.
It works best on more mainstream and established acts. It falls apart on artists with fewer sales/visibility.
I think that's a good point, and a weakness in my comment. I know everyone's watching habits differ, but I said "to a large extent they control what people watch" and then offered an anecdote to support it.

I doubt anyone outside Netflix knows what percentage browse the homepage, pick from their queue, or search for the video they end up watching. I do think it's safe to assume browsing is a popular choice, but it's not clear it's the dominant one. I'm basing this off the real-estate devoted to browsing on the home page. I think the UI would look different otherwise.

I also don't think "control" is the right word to have used, probably "strongly influence".

(I'm a PM for AdWords, sharing my personal opinion based on experience and not speaking on behalf of Google)

If you want to avoid a money pit, I think you can. The trick is to pipe conversion data back to AdWords. This is pretty easy with Google Analytics but also not too bad to set up with any analytics provider.

If you're starting fresh, you will need to spend some money blindly (without the benefit of historic conversion data). But, once you start seeing some conversions, you can use our automated bidding strategies to say "only advertise when you are confident you can drive new users to sign up for less than $X."

My other tip would be to spend some time writing good ads (clear articulation of benefits, use all of the space provided to you, and make at least 5 that can be rotated against each other) and picking good keywords (multi-word as a general rule, and specifically related to your business, not too general and not too competitive).

Finally, call support and say you're new and you'd like help. We have big teams of specialists ready to get new advertisers off on the right foot, because we know that your first couple of weeks are crucial to keeping you. They're actually really good.

Sorry. I clearly didn't do my research well enough.

But so many of these systems have only one implementation, and no spec. Matrix, Dat, and IPFS are all ahead of the game on that, even though Matrix has only one server implementation, AFAICT, and all the Dat tooling I've found is in node. It's better than Scuttlebot, in any case.

$80 will also buy a good-quality used bicycle with plenty of life left. Many of those bike boom era 10 speeds are still in circulation and some of them are truly wonderful bicycles.

Cost is an important part of the equation, but it's not the only part. Naive bike buyers gravitate towards features that make a bicycle worse for everyday use. Knobbly tires provide more grip in mud, but less grip and higher rolling resistance on tarmac. Suspension is worse than useless if you're not barreling across a bumpy trail, which is why quality suspension systems have a lock-out to temporarily disable it.

If you ask a serious cyclist to name the best all-round utility bike, most of them will name a classic tourer like the Dawes Galaxy. Here's what that looks like:

You'll find many similar bikes being sold for pocket change on Craigslist, because they don't look the part. Novices literally don't know what a decent bicycle looks like and the big box retailers are happy to pander to their misconceptions.

I think you need a temperature gradient to generate electricity from heat
Since you have to feed it ultrasonic energy to power it, I suspect it is not too bad because, IIRC, ultrasonic has a short range.

You could feed it electromagnetic energy - but then all you really have is a smaller version of the Great Seal bug https://en.wikipedia.org/wiki/The_Thing_(listening_device). I wouldn't be surprised if those already exist in about this size and the paper linked to from the web page talks about several such devices (and how they are not as well suited for implantation).
Lambda was having capacity issues last night in us-east-1.
I think calling a device with dimensions on the order of a millimetre 'dust-sized' is a bit of a stretch. While dust particles might adhere together to form structures at the millimetre scale, a google search for 'dust size' confirms that dust particles are generally at the micron or sub-micron scale. That's a fairly substantial difference.

I was expecting some crazy analogy between the a Nissan Leaf and natural photosynthesis.
So this link was sent to me by my father today and I posted it. He followed up with some historical documents from his relationship with Schwinn. I'm going to share them because I think it's a great testament to the hubris of Schwinn but also to the determination of a young entrepreneur.

My dad's efforts to become a Schwinn dealer:

Ed Schwinn's letter to dad when he changed the name of the store:
https://chrissnell.com/hn/Letter_From_Ed_Schwinn_1985.pdf
My thoughts, a bit too late:

I guess your takeaway from that story about my father is very different from mine. What I took from that was the extreme serendipity that my friend's parents happened to be in school with my dad, and that I happened to be friends with her in a different country, and that those people were still around to talk to me.

It's basically by sheer dumb luck that I managed to learn some of the most important things about the person I was once closest to in life.

Now of course, as you say, there's a way to do this well and a way to do this poorly. But that fact is, if we don't write it down it will be forgotten. We're just trying to do the easiest thing and write it down.
You know the one interesting thing about these "sane person stuck in a mental institution" stories, is they always talk about how nuts the other people were. If it were as common as suggested that normal people end up there for slips of the tongue or other mundane reasons then I'd expect there to be more "normal" people finding each other in these stories.
The comparison of photosynthesis vs energy generated by solar panels isn't very good, because it neglects the whole biology of the organism, which is optimized for things other than maximum photosynthetic output. For example, leaves are often targets of herbivory, so a plant might want to make a tradeoff [1] of less efficient photosynthesis for better herbivory defense. Or, it might be too costly to do photosynthesis, which requires the input of carbon dioxide, water, and light. In a very dry & hot environment, to get enough carbon dioxide into the leaf, the leaf will lose water by having its stomata open. Google "leaf economics spectrum" for a quick tutorial (the concept isn't 100% correct but it's a good starting point). Compare the leaves of tropical plants (say a banana palm) to arid plants (mesquite tree).

[1] I use this a teleological shorthand for "the selective environment has weeded out species that happen to fall on the wrong side of the tradeoff."
I hope this is meant to be ironic.

Some of it probably could be, but the effiency of those processes are low enough that you'd still have a heat problem. Also, recall that the energy originated with the solar panels to start with. It's a very wasteful way of generating electricity compared to the solar panels, so although it might be worth considering to recover some of the energy investment and eliminate a fraction of the heat, the net output of such a process will probably be an order of magnitude lower than the initial energy investment.
Domestication of fire predating humanity as we know it implies to me by the animal kingdom, in which case I'd question how we identified it as such.

We have a pool of elastic IPs that we rotate with Route53 using latency based routing. The ability to move the IP atomically (by moving the ENI) gives us operational flexibility. We were pretty surprised ourselves that the (huge) hotspots in our traffic distribution alone were enough to "break" the ELB, despite overall traffic being fairly low. We had to see it ourselves to believe it. The current setup has worked out well for us as we've scaled over the last year.

Also I'll add here to another point made below: I don't blame the ELB for not being built to handle our traffic pattern, despite the fact that websites are probably a minority on EC2 vs APIs and other servers. My specific critique is that none of their instrumentation of the performance of your load balancer indicates to you that there is any problem at all. That is... unfortunate.
That's pretty amazing, thanks!
Does anyone have an idea of what kind of technical problems this is trying to solve?

Her attitude comes from the privileged ideal of hard work = success, which stems from the classic attribution error: "I'm successful therefore it must be because I'm better than everyone else in x y or z ways", and often one of those factors is a belief in one's own hard work pay9ing off. Which blithely ignores all the less fortunate people working even harder at three jobs to pay tthe bills.
Can slack connect to arbitrary irc networks? If not, then it's not as close to open in practice.
I'm no particle expert, but I am a little skeptical about the interpretation of these experiments.

They are interested in the spatial spread of charge in a proton (or deuteron). And they call this the "size" of the proton. Good.

And they reason the more spread out it is, the smaller its effective charge in the electromagnetic interacton between it and some bound particle (electron, muon). Good.

So they reason that spectroscopy on that particle can tell them about that spatial charge spread. But that's assumes that the only force involved is electromagnetic.

Any additional short-range interaction between the two particles can shift that specturm. And we expect those shifts to be larger for the muon just because it overlaps more with the proton even if (a) the proton's size is unchanged and (b) the interaction strength with the elecron (at a given distance) is just as strong.

Now if there is no extra ineraction, then their methods do measure the proton size. But then they have to explain why it changes -- which would require an extra interaction.

This is cute. This is clever. Whether or not it's too clever time will tell. A year ago, I noted that Rust was starting out at roughly the cruft level C++ took 20 years to reach. Rust is now well beyond that.

All this "futures" stuff strongly favors the main path over any other paths. You can't loop, retry, or easily branch on an error, other than bailing out. It's really a weird syntax for describing a limited type of state machine.

I'm not saying it's good or bad, but it seems a bit tortured.
How Humans Are Creatures of Habit (And What You Can Do About It)
Some of it might come from creepy movies or sad history of psychiatric institutions, which is unfortunate.

However, recently there was an unexpected result regarding schizophrenia suggesting it might be just a result of a genetic bug of extensive deletion of redundant neurons in the brain, a bio-computational problem when you look at it with the eyes of a hacker. If confirmed, this would invalidate a lot of previous research and force the whole field to take a bit different, algorithmic view on many issues.
Because heat is pure entropy; it's what you ultimately end up with after electricity has been used to do work, and the process is irreversible due to the Second Law of Thermodynamics:

OT, but I love the explanation of the name of the author's blog ("The Hardest Science"):

https://hardsci.wordpress.com/2009/03/14/making-progress-in-...

The author's field of study is psychology, often thought of as the softest science. It reminds me of the initially non-intuitive reasons for why the two hard problems (naming things and cache invalidation) in computer science are hard: because their solutions are non-deterministic and inextricably linked to human decision making and needs:

> What are the “hard” — as in difficult — problems in science? Hard problems in science are those that are embedded in complex systems; they are hard because to study something well you often need to isolate it from outside influences. Hard problems are those that vary by local conditions — science seeks to identify general laws, and when something is locally dependent, you need to sniff out the complex interactions that make it so.
There are a lot of people who will not commit crime only because they fear the consequences. So it would be rational to punish criminals regardless of your thoughts on free-will. And if you don't believe in free-will then you have to accept that you have no "free" choice about punishing criminals.

Myself, I do not even know what the will is, or what it could possibly be free from. The influence of the universe?

The problem is the granularity. Everybody wants to separate based on genre when what we really need is to separate based on song and possibly then reverse to artist.

After you downvote "Faithfully" enough times because it makes you gag, Journey leaves your list.

Except that "Frontiers" and "Edge of the Blade" sound nothing like the garbagey Journey ballad schmaltz that everybody sings on karaoke night. So, you will never hear those songs in spite of the fact that you may like them.

The problem is that you can't get this information without throwing the occasional curveball at a listener. And, from the streaming app point of view, it is very risky to throw new songs at a user that you don't know definitively that they like because they might dislike it enough to change the channel, app, etc.

Consequently, recommendation engines run by corporations will only ever be totally safe and boring.
