"It’s right there on their website. These numbers do not accurately represent the price you will pay"
If you're comparing round-trip ticket prices, you should double the carry-on fee for comparison purposes, since the airlines that charge fees for carry-ons typically charge it on both outgoing and return legs.

Spirit is an American low-cost carrier with fees in that range. It's $56 roundtrip for a carry-on bag if paid for at booking time, $76 if paid online after booking, or $114 if paid at the airport in person.
>"When inflation is at the target rate of 3% that means that the central bank will default on 3% of the amount of debt it guarantees within a year."

Thats patently false. Government debt is sold in the form of bonds. They make up the bed rock of the whole economy. Precisely because they can "print money" they don't default on debt. Government bonds are considered "zero risk"

Yes, a central bank can default on foreign debt, or if they can't print their own money (see greek banking problem.)

however this underscored the fundemental misunderstanding of how money works.

>"By offering short term credit to each other market participants will be able to engage in economic exchange without having to pay the cost of money.

>Because market participants will effectively be creating new money with every transaction they will be expanding the money supply and increasing economic growth with every transaction."

Thats litrally how the entire banking system works now. Thats how credit cards work too. Thats how B2B credit works. What is not tackled here is risk. Sure free credit is great, but how do you know if someone can settle the debt? In this (unrealistic) world, the credit ratings agency becomes the dominant force.

Speaking of which, there is no reason why a small buisness can't offer its own line of credit, without using a bank. However the reason why credit cost money is because there is risk. Interest is a function of risk and supply. Sure a coffee shop _could_ settle bills at the end of the week, but the cost of administering that system is non trivial. The risk of loss is also non trivial.

Bitcoin or Etherium does nothing to stop that.

In short, this article is flawed.

If you go over to /r/credibledefense and read up on the F-35 discussions sometime it'll probably change your mind about the program. It gets a tremendous amount of unjustified hatred from people who don't realize what an impossible balancing act it is to build cutting-edge defense aerospace products, especially one that's such a huge paradigm shift.
> The weirdest part of it all is how these folks are now on the sharp end of capitalism. They're rapidly being dismantled at a more local level by on-site generation, which simply needs less global infrastructure to meet demand.

I wish the climate change alarmists could realize that 90% of what they're freaking out about is a non-problem. It'd just take a small amount of focused investment (cogeneration and AC time-shifting tech, etc) to make the energy industry obsolete.
What a load of fluff. I'm glad wired hasn't endangered it's preeminent position as the tech equivalent of the National Enquirer.
Very nice. The problem I've seen with all the other on-the-fly image manipulation services is that they can't charge but also can't stay free.
Forgive me, but more and more I see the phrase 'outer space' referring to stuff that happens at distances between the Earth and the moon. Is this a thing now?
I think the system is more complex in terms of feedback than that. A miner (Bitcoin or gold) makes a decision, based on the market value of their chosen commodity, and the cost of mining that amount, as to whether to mine or not. As the price goes up, there is a greater incentive to mine, and as the price goes down, there is less of an incentive to mine.

The core difference between Bitcoin and gold is that Bitcoin was designed from the get-go so that the more mining there is, the more secure the coin is. That is, mining makes all Bitcoins lose some value because more Bitcoins are created, but it makes them gain value because the network is more secure.

Gold, on the other hand, presents no such tradeoff -- the mining of gold makes gold less valuable by making there be more of it, but it in no way makes existing or past transfers of gold more resistant to tampering or anything like that.

There is some bidirectional feedback for Bitcoin, though it's hard to estimate the strength of that signal. But for gold, it definitely feels like you're talking about the tail wagging the dog.
> True, the success rate isn't very high, which is the direct result of the variability of whether each individual possesses the tiny bit of willingness to change, which is essential to the recovery process.

"If our process hasn't worked for you, you didn't want it to work enough" is unfalsifiable and can be used to defend any sort of quackery. Indeed, there's no way to generate a counterexample -- of someone who had "willingness to change" but for whom the drug court didn't work -- because the defender of the drug court can always claim that they "didn't want to change enough".

Pseudoscience of this sort has no role in anything as fraught and complex as drug use/addiction.

I suspect business reasons? Or lack of demand? Maybe some of the same reasons it's not open source even though there is no reason it shouldn't be? Why can't you turn this (trusted computing) stuff off on iPhones etc?

They can also be regenerated for cheap as long as the scratches don't reach the data layer and only affect the plastic protection layer. Vinyl discs, on the other hand...
They don't protect anything. Probably 90% of your catalog is out there on the net and findable with a bit of googling. In the end it's just a bad business decision. You scare away potential customers and your stuff gets pirated anyway. You're degrading your own product and artificially creating a situation where the pirated product is actually a better one (one without a watermark) than the one you are legally selling. You've got to realize how insane that is.
Interesting, it's a free to use service and the value to LTSE is that if you need a certain amount of financing, they can help you figure out how much / when and promote their services. It's kind of like a Credit Karma or Mint model but I assume it will promote their own products instead.

Well one thing they didn't mention is that these kind of blasts create enormous EMP pulses.

You can EMP blast whole continents with it. It is thought that in case of an all our nuclear attack at high up detonation like that would happen early one to disable as many electronics and communication facilities of the enemy.

Then of course countries have been working on EMP hardening military tech.

For example https://en.wikipedia.org/wiki/Nuclear_electromagnetic_pulse says that:

---

if the Starfish Prime warhead had been detonated over the northern continental United States, the magnitude of the EMP would have been much larger (22 to 30 kV/m) because of the greater strength of the Earth's magnetic field over the United States,

---

Then the Soviets also "played" around with that too:

---

The monitored telephone line was divided into sub-lines of 40 to 80 kilometres (25 to 50 mi) in length, separated by repeaters. Each sub-line was protected by fuses and by gas-filled overvoltage protectors. The EMP from the 22 October (K-3) nuclear test (also known as Test 184) blew all of the fuses and fired all of the overvoltage protectors in all of the sub-lines.[15]

A fantastic and sorely needed tutorial for orienting matplotlib into modern usage. I really appreciated his description of the matlab-style API vs the object oriented API. Also how to use it with pandas' shortcut methods.
This is brilliant!

I always say that matplotlib is more of a low-level charting API - you can do whatever you need, but it'll take a long time and a lot of code. Better is stuff like seaborn, pandas' charting support, and the new ggplot port and altair.

Also underutilized is pandas' to_excel, to_clipboard stuff where you can then transfer to whatever application and back for editing / graphing purposes IMHO.

One potential quibble. Fiat currency is given value also because the government can demand taxes in its fiat currency on threat of imprisonment or other government-backed sanctions, and thus come tax time, one better have some fiat's currency on hand. Thus it is a store of value beyond just general belief of its value..bitcoin does not have this.

DNSSEC does absolutely nothing to resolve the problem the parent commenter is referring to. In fact, DNSSEC cryptographically ratifies the status quo of the most important TLDs being de-facto controlled by Five Eyes governments.

In years of watching for mentions of DNSSEC on HN, I can't remember off the top of my head a single case in which DNSSEC was introduced into a conversation as having some benefit where that benefit was real. It's weird what people believe about DNSSEC.
Trillion man. Nothing on earth is worth that. Nothing can justify that. The amount of good you could do with such resources compare to what is been done ? Hell even if it was a success it would still be mind boggling. No entity should be allowed to spend that much on a single project except if this project is a infinite energy reactor or world peace in a can.
> (just look at space investment pre and post '92)

For some context for anyone curious about this, my summary of the tables at https://en.wikipedia.org/wiki/Budget_of_NASA is the following: It appears that the average annual budget of NASA in both of the periods 1960--1992 and 1992--present is just under $20 billion present-USD per year (ie after adjusting for inflation).

The time series behavior is that NASA's budget peaked in the 1960s for the Apollo program at over $40 billion present-USD/year (and so over 4% of the federal budget at the time), then was relatively smaller during the 1970s and 1980s, and finally slightly larger and relatively flat since 1990. Beginning in 1971, the annual budget may be summarized as within 25% of the aforementioned ~$19 billion present-USD/year, noting that the wide range primarily hides growth since then, rather than a decrease.

(I have not looked into space investment other than NASA.)
I think it's a very big problem for my descendants. This is something I am sensitive to as my parents and grandparents have left America in such a terrible state for me to inherit, and now resist any attempts to yield power.

The energy industry is fighting against both economics and ecology to maintain dominance. It does so for lots of reasons. It has no right to exist.
>> no incentive

If I see someone drowning, I have no financial incentive to go save them. But I will go save them. Financial incentives aren't the only incentives. They aren't even the best incentives.

Why might someone go into medicine and/or research if it didn't pay huge salaries? Maybe because it's meaningful work. Maybe because it brings prestige. Maybe because they enjoy it. Maybe because they care for people.

I contribute to open source software and have never been paid a dime, yet you can hardly say that open source software is inferior to proprietary/for-profit software.

>4. As per new NATO doctrine in the late 80s it was analyzed that injuring a soldier is more lethal to the enemy than killing one, as you have to expend other soldiers to carry the injured soldier. As per this doctrine, NATO moved to 5.56mm ammo, which have higher chances of injuring someone than killing. Indian Army, wanted to follow the same doctrine hence it asked INSAS to be a 5.56mm weapon, unlike AK 47 or FN FAL which are 7.62 mm weapons. Chances of survival from a 7.62mm ammo, especially at close range are low or nil.

I like bitcoin and gold, yet I don't think they have "intrinsic value". At least that's certainly not the main point. To me gold has no intrinsic value. It's just a metal. I can't eat it. I have on a personal level no use for it. It's terrible as a construction metal, I'm not interested in jewelry and there are probably many shiner alloys anyway. "Intrinsic value" is not the point, and I don't think money needs any such thing to be useful.

Money is a complex concept, but to me one of its functions is to be a tool for measuring value in economic exchanges. All other things being equal, the value of goods is inversely proportional to their amount. For instance if the amount of gold was suddenly multiplied by two, then the price of gold would drop by half.

Thus, to measure the value of goods, one needs to get an idea of its quantity. So you need to compare quantities. You thus need a fixed reference of quantity for comparison. Just as for measuring say length you need an object of fixed length somewhere to use as a reference.

That's why bitcoin proponents often also like gold : they are attracted by the idea of a fixed amount of money.

By contrast, most central banks pilot the amount of money in circulation in order to try to keep the price of goods stable. This is, imho, as absurd as changing the length of the meter because we've noticed that generations after generations people are getting taller and taller.

When prices vary, this is supposed to have a meaning in the economical sense. Prices are economical signals. Tempering with them defeats their purpose.
Right in the article:

Chances of survival from a 7.62mm ammo, especially at close range are low or nil.

JAX-RS vs. Jersey: What’s the Difference
They have been an absolute star of my portfolio since shortly before they sold a whole load of stuff to Microsoft. Doubled in price, fantastic dividends. Whatever they're doing, I hope they keep doing it.
Great idea. Here comes an idea on how to implement it:

* Everybody (people and companies) trust their bank
* All banks trust their central bank
* All central banks trust SWIFT

This is effectively a chain of trust.
Therefore, piggy back on this existing trust relationship and let SWIFT be the global CA, and let them sign all central banks certificates, and let all central banks sign all their banks certs, and now finally, let all banks sign all their account holders (=people and companies) certs.

This way, all people and companies only need the SWIFT root CA to verify the validity of a monetary decentralized transaction from a stranger, since the stranger can prove the issued IOU-note has been issued by a certain individual or company, since all banks have verified the identity of their customers (i.e KYC'ed them).

I enjoy programming in Go about as much as I enjoy wearing shoes about 3 sizes too small. As a result, it's my goal to find very good arguments against its use in any of my projects. Should I feel bad about this? If so, can you come and stop people from powerdunking on me every time I talk about how Haskell is good at something?

I'm not mocking Golang here. It is what it is. I think it's an oddly designed tool based more around making Google's turnover easier to deal with rather than helping me as a software engineer. I am expressing frustration at people who want to laud its design as "good" or "progressive" or helpful when really, it's the language equivalent of a querty keyboard layout. Designed to be about as easy to learn as anything but prevent anyone from getting excessively good with it, because large skill gaps in a workforce with turnover are hard to manage around.
Photobucket Breaks Image Links Across the Internet
This is a pretty poorly researched and written article, but the core idea of switching to a trust-the-individual decentralized network is a solid one. It seems like we'll need a couple more advances before it's reasonable, but if you can move to a system where there is no ground truth, but rather a record of successful transactions or proof of stake/reputation in an identity then you only need to reach out to the global state to see if there are outstanding deals with an identity or broken promises.

The basic idea I've been floating is something like the following:

1) Alice generates a private/public key pair
2) Alice performs some work on their public key (e.g. low hash)
3) Alice finds Bob and promises to send 0.1 BTC to Bob's public address IFF bob performs publically verifiable service X (e.g. provides boolean assignment that satisfies some constraints or rejects the problem as unsolveable)
4) Both parties transmit the unsigned contract
5) Both parties reach out to trust brokers that tell them if either party has been involved in a broken promise, or has outstanding contracts greater than their current credit. Don't sign contract if thats the case
6) Both parties sign the contract (outstanding problem here, this needs to be atomic)
7) If contract goes well each party appends this to their record
8) If contract goes poorly offended party broadcasts this to the network and gains some portion of the lost reputation.

There are many outstanding problems that are not fundamental, but serious obstacles to writing this today. The ones that I know of off the top of my head are:

1) Need well understand exchange rate of reputation -> contract value (might be doable if you can buy reputation)
2) Need non-Sybil trust brokers (e.g. trust broker with rep >> contract value)
3) Atomic contract signing
4) contracts need to be publicly verifiable.

Any problems I am missing?
It's always been a thing. It's, for instance, the sense used in the 1967 Outer Space Treaty.

“Outer space” is basically everything outside of some fuzzy demarcation line (often, specifically, the Kármán line) marking the “edge” of Earth's atmosphere.
That's the point of corporations. To look out for the interest of the shareholders. It is the fiduciary duty of the Board of Directors to look out for shareholders' interests.
