I'm not sure why anyone writing a science article would ever talk about anything being "potentially infinite". You could claim that the ability to broadcast on different frequencies gives you room for a potentially infinite number of broadcasts, arguing that frequencies are real numbers and there are an infinite number of them between any two points on the radio dial. Unfortunately, you can't simply think in terms of frequencies available, because you need a certain amount of bandwidth around each one to carry information. The more closely you pack the broadcast frequencies, the narrower the slice of bandwidth you have for each, so the more frequencies you transmit on simultaneously, the less information you can transmit on each one.

I suspect that this discovery adds another dimension, as if you took the frequency line and expanded it to a plane, but that each potential transmission "point" on the "airwave plane" would need a finite area around it in which to pack information. This new dimension may allow us to use a lot more capacity that we were previously wasting (maybe), but I'm pretty skeptical that the usable area will be "potentially infinite" except in the limited sense that the usable frequency line was already "potentially infinite".

Even so, any large increase in the effective wireless bandwidth would be cause for celebration.
The UI is still ridiculous, yeah. But that seems to be par for the course for anything security-related, especially around client-side public keys. Setting signatures for your email is ridiculous, as is receiving them - epic warnings on every client I've tried means I know I can't send signed emails to my family, because they'll freak out and delete the message or shut down the computer immediately. Until that changes, you can be guaranteed it will never gain widespread adoption.

Eventual consistency isn't about "losing writes". It's about how long it will take for all of your replicas to agree on/observe the last written versions and, in the meantime, you'll read potentially stale data.

Certain data structures inherently tolerate staleness or message reordering: look at your Twitter feed, any kind of log, or other "commutative data structures". If you can't handle staleness, you should probably use stronger consistency.

However, if you can find out about staleness after the fact (an asynchronous callback, for instance), you can run some sort of compensatory routine (e.g., overdraft charges for your bank). Then you have an optimization problem: (cost of compensation)*(number of times you have to run compensation) vs. the benefit you get from weak consistency (latency, availability, whatever).

There's an awesome paper by Pat Helland about the problem you mention regarding building real-world systems on top of inherently unreliable components. It's called "Building on Quicksand":
http://arxiv.org/pdf/0909.1788.pdf
It's all about tradeoffs and acceptable risk. A bank, an e-mail provider, and a game analytics tracking system all have different levels of risk tolerance. (Protip: delivery services already lose way more than one in 10 million packages, for any number of reasons.)

I haven't watched the talk yet either, but actually quantifying the risks associated with eventual consistency is a nice idea. It should help system designers make better decisions as to what tools are trustworthy enough for their application.

US drafts work from the bottom up. Because as you go higher up (e.g. people in college, then blue collars, then white collars, then leadership...) those people are increasingly indispensable to the war effort. In Vietnam, they made universities give them lists of the students that were doing badly to draft first, once they ran out of people not going to college.

And if I had children, I would definitely consider relocating them abroad as an option, depending on whether they personally agreed with the war and other factors.

In short, as you go up that hierarchy, people are increasingly politically active, yet are increasingly isolated from the draft.

So, if you wanted this solution to work (and I contend it's a very poor solution to the problem anyway), there are some serious obstacles.
I think you are misrepresenting eventual consistency with losing data. They are not the same at all. Good eventually consistent systems give you the option to see the entire history of a key, and if there are inconsistencies you can resolve those how you see fit. If you absolutely for a fact need to know the value of something you can do reads at high R values to make sure everyone agrees on the value. No one who markets are sells eventual consistency, be it Amazon or Basho in this case drop data in cases where consistency isn't guaranteed.

Ask HN: How do I convince non-technical people to hire me?
I just had the somewhat interesting experience of interviewing for a freelance gig at a company that has no technical staff. They asked me a little bit about my experience, but their main concerns seemed to be my hourly rate, availability, and willingness to work on-site. I tried to talk about technical matters, how I would solve their problem. I dropped a few buzzwords at the beginning but they had no idea what I was talking about. I came out of the interview without a clue whether it had gone well or not.

What, in your experience, are non-technical people looking for in a freelance hire?
I'd like to see the research supporting these numbers.

I'm curious as to how they determine the number of jobs created via their app economy.

Many of the jobs they list do not belong to them and they may actually play a small part in the job itself. Unless they own the transportation company they can't lay claim to the truck driver's job since he's probably delivering stuff for other companies at the same time.

How did Apple create or support healthcare jobs?

People working to build their stores is a short-term deal. Similar to the truck driver example, unless they own the construction company they can't take credit for the entire job.

I'm not saying they cannot lay claim to a great deal of success because most of what they say is probably true. But unless they break the numbers down to realistic examples of jobs created and jobs supported then the numbers they provide is misleading. Especially when they just lump them all together into one big number that makes them look good.

Apple fanboys calm down! I'm not mad about how well Apple is doing, they'e earned their success. They've made some great products and they've made some great business decisions, like using offshore manufacturing.

My complaint with Apple is with choice to start a dishonest conversation about jobs in the US instead of talking about why they use foreign manfacturing. They don't want to talk about their "China problem" because it's unpopulart so they spin a story about how many US jobs they have created to distract you.

If they were proud of their offshore manufacturing, why don't they have a page about that? Don't hold your breath waiting ro that one.

Why would they put that page up? What's in it for them? It distracts you from the problem and makes you like them for creating jobs they had to create anyay.

"35 is the end for developers"? That's ridiculous! There are many developers in their 40s and 50s (I'm 40+). This is like saying 35 is the end of physical capability: there's some truth in the assertion (the body start to decline) but it's a question of keeping yourself in shape, I've seen many 60 year old guys at the gym that can hold their own against any young guys.

Great presentation Mark! This is what I LOVE about Basho - use science and metrics to show how their Riak compares to other NoSQL stores rather than marketing.

TL;DR version: In all databases, you have to choose which 2 parts of CAP you want: Consistency, Availability, Partition tolerance. If you choose Availability- just HOW Consistent is my data? If I want my data to be more consistent, then how does this affect my availability? This gives an actual formula to calculate the best design that meets your applications goals.

This is beyond pathetic. Who exactly are Apple trying to impress with this?

To summarise, they highlight 514k US jobs created of supported by Apple. Now the two operative word in that sentence is "US", and "supported".

1. Direct jobs created for US citizens who are on Apple's payroll is a fraction of this. (47k), so about 9%.

2. They say US jobs, because do you realise how much they outsource?

I personally don't have a major issue with outsourcing. Go where ever the labour is cheap. (And in Apples defence they do try and stay as transparent as possible with Foxconn and employee treatment ethics).

Obama asked Jobs directly once, "what will it take to bring Apple manufacturing back to the States". That is never going to happen. But again, I don't have an issue with that, but spinning their profiteering into philanthropy is utter crock-shit.

Do you realise the jobs they are listing within their "supporting" grouping?

- Business Sales

- Healthcare

- Customer Sales

- Transportation

Who are they including in this? BestBuy employees? The 40% of private Doctors that now say they use as iPad professionally and the FedEx employees who ship the goods on overnight freight?

I'm just suprised they left off the pilots who carry the cargo. They could have squeezed another 400 jobs into that number for sure.

Ultimately, 99% of these people all had jobs before Apple. The truck driver delivered his goods. The healthcare professional was still practicing and the salesmen were still selling. (How by the way does Apple create healthcare jobs?)

Don't read this for anything more than it is. PR bullshit.

Do you know what Apple doesn't want? Some campaign runner trying to decrease US unemployment numbers by saying that the largest US technology company needs to start employing more people. This is a pre-emptive PR measure.

Hi ebbv, I'm the author of the post.

I've had a quite a bit of feedback that I've moved the viewing distances too far out. I measured from my own experiences, but I guess I must be atypical. It might be because I use dual monitors on the desktop (I have a 27" and a 26", so I sit back to reduce head turning) and slump when I have a laptop in my lap.

Anyway, I've expanded the spreadsheet that goes with the post to include some extra settings for closer distances and for your specific distances and devices.

Hope this helps!

By the same logic Foxconn could argue that it's creating jobs because it makes things that get shipped around as well.

I'd be very careful about going back to school for a serious amount of time in the software field.

Partly because I believe a lot of experience can be gained by yourself, in a much shorter amount of time. Think of it this way: 6 months of hacking code in the evening should get you pretty close to where you want to be.

Recent software college grads get hired by large companies, and frankly I think they'd wouldn't look at your resume twice. They'd pass on you in a heartbeat.

Edits Quarterly
This depends. Even with W=R=1, you still send each read/write to every replica. If the replica that acknowledged the write fails, the other two replicas should eventually receive the write.

But--what happens if the write messages to the other two replicas drop? Well, typically the coordinator will hand the write off to replacement replicas (hinted handoff/sloppy quorums). Alternatively, when you detect the message loss via a timeout you could retry. But what happens if the coordinator dies and can't retry? Then you'd better replicate your coordinator. That gets hairy, so hinted handoff and sloppy quorums are easier. However, whichever way you go, it's definitely possible to handle an arbitrary (still fixed) number of node failures without data loss.

In general, though, sloppy quorums/hinted handoff solve this problem. I haven't heard any data loss complaints with Riak/Cassandra/Voldemort due to replication, but I'm very interested to hear if you have.

You can definitely extend PBS to node failure cases/sloppy quorums/hinted handoff. The main reason we didn't was because we don't have good failure data. There's nothing stopping you, and, as we point out in the paper/backup slides, you can potentially hide this in the tail (e.g. the .01% of stale cases) provided your DB "does the right thing".
You are not making sense. Apple sells more product outside the US, too, so who's to begrudge them having a large percentage of employees overseas?

The rest of your accounting complaints are simply not true. If Apple represents 1% of UPS delivery business, they can rightfully claim to have created 1% of the UPS delivery person jobs.

And of course it's PR. It's PR designed to counteract some clueless congresspeople asking for economic impossibilities from a very visible US success story. But it's honest PR. Such things do exist.

Geeze Louise. I don't think flagging, on this site, is meant as a downvote for articles where you disagree with some terms' definitions.

>The United States made a huge mistake in moving to an all-volunteer army in the 1970s. With a draft and mandatory conscription, everybody had the common experience of serving and perhaps doing really bad things in the line of duty.

Are you seriously proposing that, instead of sending in a few thousand well trained guys who can do the job, it's preferable to send a few million who can barely fire a rifle - just because it may make for effective anti-war propaganda? If you are truly serious, you should at least know that it doesn't work. Only Vietnam turned a significant proportion of its veterans into anti-war activists. Korea, the World Wars and the Civil War had no such effect.
I think the OPs concern is more with his lack of experience combined with his age. Not just that he's in his 30s, but that he's in his 30s and has almost no work experience.
I'm pretty sure there is a general consensus that young people learn faster, and this might seep into a decision in whether to hire a 20 something with no experience or 30 something with no experience.
Like I said, 2%. This is the allowance that Grossman and his research support as being "sociopathic/psychopathic". Infantry units on average would make up close to 10-30% of an Army, depending on the force. The whole book is about the factors that can increase/decrease PTSD occurrences, but his basic point is that killing is so unnatural that PTSD is the normal part of the human reaction to killing. (IOW, everyone gets it to a degree).

He also does not say this 2% is pre-disposed to joining SF units. He does, interestingly enough, suggest that the data does point to this 2% being pre-disposed to mercenary work.

Quick and Easy Inset Effects
Regarding the undercurrent of anger that seems to exist regarding Stack Overflow making money: SO has a great model that is incredibly useful and helps many, many people. They have created massive value. SO making more money means more people being helped, and yes, a well-deserved return for the founders and team members who poured their lives into creating and supporting such an amazingly useful resource.

This is a good thing.
That's simply not correct. Foxconn creates zero consumer demand. Consumer demand creates jobs.

They can demand all they want, but most govts give themselves rather wide immunity wrt such things.

They have the authority to block sites. They have procedures for doing so and have wide discretion as to what procedures to use. They made a small mistake in applying said procedures.

"As it is now, the vast majority of civilians have absolutely no idea what military service is like. In this lack of context everybody becomes really impressionable."

When you vote, you are exercising political authority. You are using force. And force, my friends, is violence, the supreme authority from which all other authority derives. Whether it is exerted by ten or ten billion, political authority is violence by degree. The people we call "citizens" have earned the right to wield it. Naked force has settled more issues in history than any other factor. The contrary opinion "violence never solves anything" is wishful thinking at its worst. People who forget that always pay. They pay with their lives and their freedom.

Who do these type of anti-MBA sentiments apply to? Do a lot of people enroll in MBA programs to "learn business" so they can start a startup, or do they enter MBA programs to learn management so they can get a job in corporate America? I've always assumed its much more the latter.

I could be wrong, but I don't think McKinsey is going to be terribly impressed with a sole story of "learning lots" from launching an App Store app.

I think its good advice for people entering MBA programs for the wrong reasons, but I'm just not sure how large that segment is vs. traditional MBA students.

What else do you want Apple to say?

It is common knowledge that they outsource manufacturing overseas, and it's common knowledge that they do it simply to maximize profits, however, it's not something to be publicly proud or ashamed of, it's just business.

Making lots of jobs in America, OTOH, is very positive.
