How did you cure your chronic back ache? I'm having issues right now which I think are being caused by anxiety but I'm not exactly sure how to address them. I've started doing a lot of exercise though, perhaps that will be all I need.
The story behind @ sign
Sounds like a terrible idea.
Jet fuel prices are half what they were ten years ago:

https://www.eia.gov/dnav/pet/pet_pri_refoth_dcu_nus_a.htm

Prices peaked in 2008, dropped during the recession, reached that peak again in 2011 and are now even lower than they were during the worst days of the GFC.
Agreed. Obviously the mafia doesn't participate in surveys so, barring criminal charges or conviction, anecdotal evidence is the best one can hope for.
You're getting voted down but you might actually be right... if I had ever suspected this I wouldn’t even leave the house.
When using green chillies in Indian gravy (i.e. wet) dishes, instead of adding and cooking them in the traditional way, try slicing them on both sides longitudinally (also remove heads and tips), and then add them to the dish somewhere in the middle or near the end of cooking. I discovered this technique while experimenting, and found that the resulting taste of the dish differs from the traditional use of chillies. It gives more of a good flavor and less of heat / spiciness.
So, are there anyone already doing this? From the attitude towards Comcast, it looks like there will be lots of funding from people dying to get a better alternative.
Point to point is more efficient if you can fill the plane.

Hub and spoke - an indirect flight where you perform extra inefficient landings/takeoffs.

Direct flight - shortest possible distance. Maximum time in the most efficient configuration.

The only issue is that you have to fill the plane to 100% and that might be harder with direct flights between certain destinations. Although i'm sure modern booking systems (automatic pricing to fill all planes) help a lot with this.
Try a 787 sometime, you'll have a similar experience.

It has everything to do with being a new plane with new technologies (higher air pressure, better lighting, newer seats, etc.). Nothing specific to the A380.
On this specific Verizon issue - you can set up a "move" with Verizon on line even though you're moving to the same address and you can get the nice gigabit deal. Search for the details. I did it. I was surprised it worked. Nice reduction in cost and better speed.
How about something pithier, like "Joykill"?
>My local mechanic is required by law to tell me how much something is going to cost me before they start work. Why is my doctor not held to the same standard. Ever tried calling a provider to find out how much something is going to cost?

Does that include a situation where say, when emptying out the oil, the nut over the drain breaks off which necessitates changing the oil sump, except they then discover the engine mounts are rusted and now the engine needs to be lifted and the mounts replaced? (I'm not a car guy, but I hope this demonstrates the thought even if inaccurate)

Software folks mostly do:
"I will do mgmt's random projects and requests for $xxxxxx a year."
As a speaker of English where "do" and "due" are not pronounced the same I assure you it's "do".
The 787s had a bad habit of catching on fire in midair shortly after they first launched, and they seem to have been fairly successful since then. Like any other industry, airlines have a wide gulf between "absolutely perfect" and "good enough".
It sounds like your idea of a payout is an acquisition. There are many companies especially outside of tech which are profitable and do not require a buyout.
I don't think it's a straight-forward decision and is influenced by a number of things;

1. desired time to market.

2. operating cost.

3. people cost.

If you're dealing at that level of traffic you're not going to go broke unless you lack a decent business model. One of the companies I worked at was spending $100,000+ per month on AWS (more than they should've for the incoming traffic level but they survived for a number of years). A friend was working at another company that was spending $3,000,000+/month. The motivation for using DynamoDB/Datastore over say S3 is that you can do range queries, field sub-selection, offloading of systems administration, some elements of security, etc.

Most traffic patterns have windows and tend to be diurnal in nature. This depends on the number of timezones your service covers. Obvious exception being IoT type time-series. So you might experience peaks of 16k/s but that will be for perhaps a few windows in the day. I also wouldn't be treating DynamoDB as permanent "long-term" storage for granular data. I would be using a sliding window of whatever I consider to be a valuable retention period (e.g. sliding window of 30 days). If you don't you'd need to scale C* as well.

In order to run Cassandra and get streaming aggregation via Spark you need to run "2 regions". One as the primary online region for serving requests and a second region for stream processing using Spark. Minimum recommended memory requirement is 16GB for a C* node. For a C* + Spark node minimum is 32GB. The more the better for both. If you've selected your keys well C* will scale almost linearly with the addition of nodes. Using Netflix 1,000,000 writes/second as a model you could roughly state that dividing nodes (285) by 60 should yield an approximately similar throughput requirement to the articles. So about 5-6 t2.xlarge nodes could potentially work for the FE cluster, and whatever gives you adequate streaming performance for the streaming cluster, as a minimum 3-5 x t2.2xlarge. Let's say ~$2,000/month.

Another thing to consider is that the management and maintenance of a C* cluster doesn't come for free either. So figure you'll need a minimum of 2 sys-admins to administer the cluster. Depending on where you are that'll likely cost the company upwards of $400,000 per year or $33,000k/month once you combine base salary, pension contributions, taxes, etc. You could say 1 sysadmin but then you're going to burn out your sysadmins if 1 guy is always on-call.

So assuming a sliding window of 30 days that's $2,160/day for DynamoDB. With a C* cluster you're looking at a minimum of $1,100/day. More depending on how well it performs for what your system is doing. If you're not using a sliding window you'd also need to scale you're C* cluster as well. In order to configure the C* cluster in a way that provides back-ups, auto-recovery, etc you're probably looking at about 2w-2m depending on experience. Whereas DynamoDB time to market will be probably a 1-2w.
The A380's engines were developed in the early 2000's.

Newer twin-engine planes (B737-MAX, A320neo, A330neo, A350, B787, the upcoming 777-X) have improvements in engine efficiency that have not been ported over to the A380. Airlines operate on wafer-thin margins, so even a percentage point increase in engine efficiency is huge.

Granted, the engines themselves are not made by Airbus, but there are integration costs involved.

There are other economic issues:
(1) It's just hard to fill an A380 year-round. Not an issue on trunk routes like SFO-LHR, but there are only so many of those.
(2) If slots at airports were auctioned out, you'd arguably see more demand for larger planes - maybe not the A380, but 777 or 787 sized.
I see you're being voted down but you might actually be right... if I feared that kind of monetary consequence I'd never walk out the door.

Err, are you asking whether the internet was useful during/prior (and despite) the dot.com bubble? The answer is, yes, it was hugely useful. Initially for information (e-mail, ftp, finger, usenet, gopher, WWW), later for commerce.

It was far more useful, and far more frequently used, even years before the dot.com bubble, than cryptocurrencies are now.

If you took away cryptocurrencies right now, impact on me and almost everyone I know would be basically nil. If you had taken away the internet in 1996, I and many other people would have complained.
Yeah... I tried explaining this to my ex-boss once. The math just isn't that complicated. I think MBAs are trained to ignore any math that doesn't suit their position.
Your post feels way out of character both for HN and for how you’ve interacted with others here on HN in the past - it seems like there must be more going on behind that post than your readers are able to intuit from your anger. Can you elaborate a bit more?

Well, you dont use your insurance for maintenance, you use it for accidents.. Compare accidental repair prices to medical prices, since you do use insurance for regular doc visits, comparable with maintenance

It's probably more accurate to say that airlines have tended to move toward more and often smaller hubs augmented by some point to point flights than that they're abandoning hub and spoke entirely.

Project STAR*: Streamlining Our On-Call Process Engineering
The grammar is relatively simple. In general having syntactic constructs that are seen as complex by humans (on the grounds of unreadability or counterintuitiveness) says nothing about complexity of the formal language that describes such constructs (and in fact for most practical languages often ugly constructs are the effect of the grammar being simple, not the other way around, for somewhat extreme example of this try comparing say SQL and RPN).
That evidence also speaks to premeditation, and mens rea.
If nothing else, "what's the largest prime number you've found?" would be a fun question to ask another intelligent civilization, should we make contact with one.
That implies there is a viable alternative people can go to.

How does it work? Who host the files?
The 787 replaced the 767 in Boeing's lineup, which in turn was competitor of the 350. The 747 is still incredibly successful for cargo, so the 380 didn't replace it; it is absolutely nuts that AirBus didn't come up with a cargo version of the 380 yet.

Next up is the 777, which has higher capacity than the 787/350. However, it is modern enough that it can probably just be upgraded, no new plane is needed.
That is an argument that probably could, and therefore should, be made without making it dependent on the tragedy of the commons being a fallacy.
Alright, that's a good one :)
Creating responsive iframes using only CSS
The big airports cost more to land at than the small ones, Ryan air might say it's landing at a city but actually be at a rural airport an hour or more away.

If the plane loads are good enough and the plane is scheduled in such a way that it always returns to a home airport for maintenance then I can see how it makes economic sense even if logistically it's tougher.

I don't think there is a PL that is harder to parse than C++.
It is not as if the extra $44K goes all to the admin's payroll. Rather, if you have more personnel, it means you are running a bigger, more complex operation. That demands larger facilities, more equipment, a wider range of skills in your workforce, etc, and that all costs money.

Furthermore, given that all those things require heavier capital investments, it makes less likely that the surgeon performing the surgery is a (partial) owner of the hospital itself, but rather a highly compensated employee. There is a double-bite effect there:

1. The doctor's interest is less alligned with that of the hospital, so he will demand higher compensation for the same amount of work, at least of there's enough scarcity of doctors to justify it.

2. The capitalist owner will naturally expect a return of investment. It is subtle, but in this case the expected profit is proportional to the total capital investment, not the number of hours/services provided.
There are attempts to do this, for instance Primecoin and Curecoin.
There's a site for large prime numbers, and I wondered Mersenne primes have been the largest primes known - since 1992, and since 1952 with an exception for 1989 to 1992. GIMPS - https://www.mersenne.org - has topped the list since 1996.

I've been wondering for a while now why health insurance companies exist at all. They introduce a massive bureaucracy and massive costs and provide very little value.

They evolved from a reasonable idea into a monster that just drains our system and do not provide enough value to justify their existence in my opinion.

Very practical, that's how some backhaul works(and why you see giant microwave dishes on mountain towers).

This Ars[1] article does a great job covering what goes into it. I know of more than a few WISP out there in WA state. They can't do the same data rate as fiber but getting a connection is pretty straightforward if there's any large mountains nearby.

The goals here are "on(A,B)" and "on(B,C)". Clearly these are not independent.

The problem is that neither can be done before the other. If you start on one, it blocks the other. I'd've thought this was clear from the article, but since you ask the question I assume it isn't. That being the case, what are you suggesting that isn't covered in the article?
The threats against SMS are not advanced. ESN porting attacks are still -easy- in the US and I have personally had to be a first responder due to an administrator at an employer being hit by it. Suddenly you lose your 2FA backup to everything and an attacker resets all your passwords and takes over all your accounts.

Any aging windows XP machine at a corner cell phone store has permission to port your number.

Even if that gets fixed, in the USA all cell service providers are required to retransmit a message with A5/1 encryption if asked which can be intercepted and decrypted with wireshark, a $20 USB TV tuner, and 2TB of disk space for rainbow tables.

Seriously SMS is downright dangerous as a 2FA method and it is idiotic that vendors support it as a password reset method.

You are better off using nothing at all over SMS to avoid a remote account takeover... or use something that -can't- be remotely stolen like a hardware TOTP/U2F device.
You can't just take the seats out and fill it with boxes? What else is needed for a cargo plane?
Hub and spoke allows the airlines to keep costs down by using smaller airplanes for the spoke routes which can be contracted out to smaller regional airlines that pay their pilots peanuts.
Yep, but that’s a legal requirement tacked on by governments, not an actual theoretical requirement.

It is amazing how long the USSR lasted as long as it did. I think in the end all communist regimes fell because of the failures of central planning(even though it bore gems like Linear Programming and Ukraine's then booming agriculture and the Space program). I think its failures were tied to economic failures, if you can make the economy work for the masses, people really don't care for much else it seems....
> Today, you can get 200/10 for $100/month. Not bad, but head a bit east to Salisbury, MD and you can get 1000/35 through Comcast for $105 ($80 for the first year). That's the big fear with municipal services. Upgrading head ends won't get you press like rolling out a broadband service in the first instance will.

A counterpoint to your argument is Time Warner didn't improve speeds or customer service until Google Fiber started building in Kansas City. Only a few ISP's serve large parts of the country. If they can ignore you while getting monopolistic profit, they will. Building a locally owned competitor might be the only way for lower tier cities and communities to get the gigabit fiber and proper customer service that is so attractive to techies like me.

Edit: Now that I think about it. I have only seen your 'fear' come up once. With Provo's locally owned fiber, which yes, they seemed to have bungled. They did get Google to come and take it over. Many other places have done so much better. Noah from AskNoah/Jupiter Broadcasting lives in Grand Forks, ND. When they had a flood that required them to redo the sewer system a decade ago they put in fiber and now have gigabit internet to residents.
Aye. It's a similar situation for DFW. The original master plan called for thirteen terminals (see pic [1]), not including the additional cargo terminals/ramps. It currently has 5, and although it will probably never expand to 13, there is enough land space for plenty of expansion.

But if a controller/action is simply a pubsub middleware between the domain and responder, won't this mean that the number of controllers would be insanely low, since you could have one base controller shared across most domain/responders?

Yes, you can be anonymous on HN - that assumes you've stayed anonymous. Obviously these people didn't and so they need a new account. The motivation is huge.

No it isn’t. Make a new key-pair for the signature. This key-pair will also be anonymous. Best of both worlds: still anonymous, but you keep the option to positively claim it later.

The fact that they’ve spoken about it on HN somewhat deanonymizes them, sure, but perhaps not meaningfully so yet. The OP needs to secure against a private company’s security and legal teams, not a theoretically omniscient naion state. If he used an alternate IP address for this throwaway, he’s still basically fine.

This isn’t poor advice. Speaking for myself, I choose to give this advice as a security professional and someone who has had to make various disclosures, both “responsible” and “full”, and of the latter, with and without the cooperation of the company.

Look, I was there from the mid 90s. I'm curious about the various viewpoints, as well as a more objective, less biased summary which attempts to ignore the nostalgia factor.

> Initially for information (e-mail, ftp, finger, usenet, gopher, WWW), later for commerce.

Thanks, OK, those are examples I can work with.

E-mail -> Still exists. Was it better back in those days? We had spam back then, right? Although not so much in the earlier parts of the 90s. FWIW, I did not have access to IMAP server. I had to use POP3 and webmail instead. Nor was IMAPS or POP3S used. Man, did POP3 and webmail sucked (until Gmail came along).

FTP -> Barely used anymore. Perhaps only in "the scene", though I know in the end of '00s that already happened via autoxfer bots. We got better, more secure means of data transfer though.

Usenet -> Still exists. Spammers largely moved on. Now and then two worlds: text and binary. One grew a lot, but a lot of smaller providers didn't grow with the insane data storage amounts. So a few big players nowadays. Same with ASPs (aka ISPs) in general for that matter. It has its + and - I guess.

Finger -> Replaced by blogs I guess?

Gopher -> Barely used anymore. Replaced by WWW. I didn't experience Gopher. My first browser was Netscape 2 <3

What about the more server/UNIX world? Was that better back then as well, with these large UNIX molochs like NeXT, SGI, HP, SUN, IBM, SCO?

Arguably though, the widespread adoption of TLS/SSL has made us more secure now than in the 90s. Back in those days, we did not have technologies like Tor.

> If you took away cryptocurrencies right now, impact on me and almost everyone I know would be basically nil. If you had taken away the internet in 1996, I and many other people would have complained.

I wasn't looking at it from that angle, I assumed the OP was comparing the internet of then with the internet of now; not comparing cryptocurrency.

Cryptocurrency is just a pleasure to observe for me, like rats running around in a cage. A bunch of NTs getting manipulated by a small number of psychopaths, that's how I'd sum cryptocurrency up.
