One of my teachers was in the French Foreign Legion and he told me that in a fight one should aim to inflict maximum pain and damage as fast as possible.

Needless to say, my classwork improved after that conversation. I jest, but he was quite intense.
I don't see a problem with effective metrics; they might help identify where teachers might need help.

The problem, is that usually nobody really does proper statistical analysis. The metrics I've seen, are usually like "mean student grade performance". In which case, what you'd want to do is have a really small class of smart kids. (Ergo, kudos to the teacher who finds a way to dump the idiots.)

I do think, however, you could do polling of teachers by asking the students, teachers, and other staff. In most cases you could easily have enough coworkers to figure out who's respected and who needs help.
I think that it boils down to writing arbitrary data in memory (so that they can't follow the usual path of programs, as with compilers). For the anecdote, a friend of mine used to flash a "hello world" program into a microcontroller using push buttons only :)
You think b) even though Apple printed and sent out hundreds of invitations featuring prominently an iPad3 with a clearly visible retina display?
I disagree with most of this. "Always assume the worst case." That's terrible advice! The worst case doesn't always happen, that's why it is called "worst." It should be "keep it in mind." Following a list of absolutes like this will hurt as much as it helps.
True, they have to adapt the product, but, still, they start from the lessons the competitor already learned. Not all models adapt equally well to every market, but they appear to have a culture of "fail cheaply" sufficiently ingrained to lower risks. They are a very lean business.
So it's okay that Twitter, Facebook, Path, etc, all have my contact list and possibly more? The point isn't that users trust they are keeping the data safe, its that they took it without asking up front. Those apps may be out to make its users lives easier, but I would like to know when they are taking my personal data and keeping it for 18 months in an archive

Either way, TC was/is lame. PandoDaily is too.

I've played such games a little but never thought of the people I was playing with as the enemy. The people you play with are your friends normally aren't they?
Unfortunately, I agree. From the first time I saw this technology the top application that jumped off the page to me was of a military nature. Perhaps a day will come when this may not be so. Until that day comes, tech like this, I believe, will save lives; on and off the battlefield.
The numbers aren't necessarily off - he does couch the numbers to begin with, but he also takes pains to specify he's talking about frontline combat units, not the service in general. I don't have the numbers to hand, but the US military has a ton of support staff (ie non-frontline) - it's possible that these numbers are more similar than they appear.
I think Upverter might be one of the most important app that exists today.

Try pitching them internationally in schools, colleges, universities... You will gain overwhelming momentum.
Interesting read. Can I just ask, why are you guys giving up so easily? It seems like you only launched Whim 3 months ago. Granted it might not have been successful as you anticipated but you shouldn't shut it down.

I've released a few apps on both the Android and iPhone stores and the hardest lesson I've learnt is that creating a great app is only half the battle. There are over 500k apps on there. Chances are most people don't even know it exists.
Instead of shutting down and moving on you should continue supporting it. You need to build a community. When you release your next app you can use existing apps to advertise new ones. People will recognise your work on the appstore if you provide great support.

If you consider content removal evil, I think you need to get your moral compass re-calibrated. There are numerous adjectives that could describe that specific situation, like stupid or even lazy, but evil is a stretch.

When the Feds can come kick your doors down and haul your servers out for non-compliance, what choice do you have? Not to say Google is good either, but the content mess isn't really their making. In fact, their technology has helped more than hindered the spread of content.
One of the Rackspace employees said the same thing [http://lnkd.in/m3cQhJ], but I disagree with the support argument. Even if you include AWS's Platinum support (guaranteed 15min response, see http://aws.amazon.com/premiumsupport/) it's an extra 10% of the monthly AWS bill so around $7K for 3 years in the example that was mentioned in the blog - which is still a lot cheaper than total Rackspace costs. I think it comes down to Rackspace not having reserved instances, which is why AWS is much cheaper (not support).
Ask HN: about multi-core computers and OSs
What are the limits and problems associated with multi-core computers and the software that controls them?

Currently the top-of-the-line consumer products seem to be quad core computers, and I've read about octo-core and up computers existing (Intel's products: http://en.wikipedia.org/wiki/List_of_Intel_Xeon_microprocessors#.22Westmere-EX.22_.2832_nm.29)

I suppose one big problem on the software side is that most operating systems wouldn't be set up in a way to optimize performance gains from these CPUs, making them an expensive waste of money. I'm also curious as to what some of the hardware limitations are (floor planning and signal timing constraints perhaps?).

I'm thinking of pursuing research opportunities in systems programming for multi-core computers, so I wanted to try and get some insightful info and input if that's going to be (or already is) an important field.

Cheers.

TED Talk: Susan Cain: The power of introverts
Some good points as far as getting noticed in the app store. We're definitely not giving up, though. We've submitted a new app which is a pretty big follow-up to Whim based on What we learned, but is fundamentally different enough to not be called Whim. In addition there were some legal issues with the name "Whim", so it made sense to just shut down the app and focus fully on the next app we've submitted.
The same way Bush was elected. Apathy.
I guess the fact that Rackspace UK charges in GPB doen't help either, AWS EU charges in USD so the exchange rates work in their favour as well when comparing costs.

What HN users don't mean to be
Two reasons:

1. The proponent of the new law wants the support of the police union, appear to be tough on crime, and point to his support for law and order in the next election. 'Protecting people' -- with a subtext of 'people like you, my campaign donors'.

2. The rest of the legislators are either in on party lines, want to show law-and-order support, or just didn't pay attention. Yes, I'm serious about that last bit.

When was the last time you heard of laws being repealed voluntarily rather than being found unconstitutional? Massachusetts' knife laws read as though the person who wrote them had just been watched a 1970s martial-arts film marathon and called it research. In New York you can sell slingshots that you can't legally possess.

Look at the incentives for legislators: they're not well-aligned with the goals of having a good government, no matter what you think that means. All the incentives are to pass more legislation or to score political points that bear little resemblance to what ordinary rational citizens want.

It's not just Illinois.
1 can add significant time and complexity to your code trying to figure out what date format, for example, should be shown to various countries or regions. The easy solution would be to show one and provide options, but then which one do you show? Do you do geoip? Then what language are you going to put it in? Do you outsource translation, or hire a translator? How do you moderate user content on a multilingual site? Do you show local prices, and if so, how often is the conversion updated (if at all)?

There are serious logistical problems to tackle, not even counting getting it all running and bug-free for every use case in every language with ever data format possible. It's a huge setback, especially if you stand to gain nothing significant from being worldwide.

Cost plus pricing. You should definitely know you numbers like the customer acquisition cost etc. I agree with you there. But relying on the cost to come up with the price point usually leaves money on the table. Price based on the value for the customer, not your cost.

I hope these guys aren’t trying to suggest that hard-coding the specific css-animation logic into the "show" function of a generic "page" view is generally good practice when building some complex app.

It's fine for a quick demo, but that’s definitely not where such logic belongs for any kind of maintainable project.

"In the recording, which the one juror said was replayed several times in the jury room, Alejo was heard explaining to Moore that she might be wasting her time because it was basically her word against that of the patrol officer. Alejo also said they could 'almost guarantee' that the officer would never bother her again if she dropped the complaint.

"'When we heard that, everyone (on the jury) just shook their head,' juror Adams said in a telephone interview. 'If what those two investigators were doing wasn't criminal, we felt it bordered on criminal, and she had the right to record it.'"

>Piracy isn't a moral resistance 'code'.

Why? Because you say so? I don't think so.

>It is just a way to get things for free with a (very small) chance of any repercussions. If some new magic technology was invented overnight, and the risk of being sued went up to 99% every time you tried to download something in violation of copyright I think this 'moral code' would disappear quite quickly. This is a cover up for 'I want free shit, and I am not going to get in trouble, so I do it'.

What I'm saying is that these repercussions are completely unjustified and morally wrong. Appeals to (imaginary, and quite frankly, impossible) force don't change that. You're essentially saying the same as "If being gay was against the law and we had the power to crack down on gay people, that would make being gay wrong".

>How about going to each and every artist you believe you should be able to download for free and get their permission to copy their art first?

I must present you with a counter-question instead: based on what moral authority should an artist (or anyone else) be allowed to forbid me to copy art?

Let me say it again: there's nothing more inherently good and natural than sharing. If you are opposed to sharing (of a truly non-scarce resource, at that), then it's you who's arguing against one of, if not the most universally accepted ethical practice of humanity.

Take note that nobody can be forced to share. The opposite, however, holds true as well: you can't force people to stop sharing. Or to put it in another, polemic way: if you don't want people to share your art, lock it up in your basement and never show it to anyone.

>They created their work for your entertainment, it should be their decision to say weather you can have it for free, or for a price.

I don't see why. Sure, they can charge people for distribution done by themselves if they so chose. That doesn't mean they have any authority to tell people who acquired a copy to further share said copy, with or without compensation.

> In the long run, verifying the functionality and intentions of software and hardware are probably roughly the same problem

Both require trusting the source code (a languages problem), as well as trusting the translator. In the case of software, the translator is an end-user accessible compiler/interpreter which is itself more software, thus recursively auditable.

In the case of hardware, the translator is an entire institution, which can only be trusted if you have recourse against said institution. As an individual end-user (uber alles) can then never fully trust their hardware, it makes sense to draw a line in the sand and proceed from that assumption.

An intellectual argument is irrelevant in the face of the masses

No. If you look at history, from the middle ages until now, you see a continual improvement. Moreover, the idea that people are brutes is disturbing. We have to see people as reasoning individuals; otherwise, we decay into fascism, religious extremism, etc.

Why is it so that Pakistan can have the atomic bomb, but not Iran? Why Israel and not Iraq?

It's fine for nations to have it where it represents absolutely zero threat, from the perspective of the agent (in this case, the US). Pakistan should not have it. (Remember, Pakistani leaders knowing sheltered Bin Laden.)

I only am worried if he is actively hostile.

There are many groups that are actively hostile that are not identical to a national government. There are many national governments that are largely sympathetic to these groups.

so many problems would go away if people would just accept that some day their ticket comes up, and do the best that they can in the meantime.

Dude, you're asking me to just lay down and let the terrorists kill people. No way. We should just stop the bullies. There should be no tolerance for that kind of shit.

The proper response to most of these statements is, of course, "So don't."
This theoretically true statement "There is no reasonable economic justification for a customer to offer anything but a low-ball figure. " can, in practice, be irrelevant.

So unless you are a savant, following the OP's advice in enterprise sales can result in you leaving hundreds of thousands of dollars on the table. Because customers (especially at the early stage) often have a perceived value for something that is far more than you realized, or they have a budget, and their price is the budget. Steve Blank has great examples of these situations throughout his career.

The OP's advice makes sense for consumer sales (and I think he should clarify this).

This book gives a rounded and intelligent set of tools that work in almost all situations — and will make you rethink the thoughts you thunk about pricing: http://www.amazon.com/Winning-Profit-Game-Smarter-Branding/d...
"I just did this with a new product we launched. My lowest plan was priced at $9/month. We did a usability test with our target market and ask them (at the end) what they expected to pay for a product like this. Only 1 person said a number lower than $20/month–and they went as high as $100/month."

However, that doesn't imply that they WOULD pay that for a product. The conclusion they might draw (validly or otherwise) could be "I'd expect to pay a lot more for this product, so I won't even consider it an option - it's out of my range."

I might expect to pay $1,000 for a table for 4 at one of Gordon Ramsay's restaurants. I might be pleasantly surprised to find the average bill around $600. That doesn't mean I'll pay $600 for that, though.

That's not what I consider in general, and I don't know how you came up with that reading.
