Writing specifications, and knowing which items in the roadmap bring the most value to the greatest numbers, are hugely different beasts. I definitely took the PR-driven approach to mean identifying those 2 items, even if taken by themselves (without the rest of the roadmap) they are meaningless. This is a massive, valuable skill to have...and one I'm not sure how to acquire. Don't know if this convinces you, but the article really spoke to me.
This just means you can't lecture. One thing the digital, scalable lecture isn't going to take away is the importance of one-on-one instruction. In fact it may exacerbate it.

To me this is the future of teaching for most teachers - whereas currently they may spend ~10% of their time one-on-one with students, in a future model I can see that figure climbing to 80-90% percent as students struggle with their homework after watching their Coursera/Udacity lectures.

Not sure how you'll feel about that but personally I always found individual instruction to be the most challenging and rewarding part of teaching :)

Padmapper's isn't "reposting" any given listing -- it displays an abbreviated digest of the listing in its search results, and then if the user clicks, it takes them to the original listing.

If this is illegal or otherwise objectionable without an explicit agreement from each Craigslist poster, I'm not really sure how a search engine or even descriptive hyperlinking is kosher without explicit agreement from each website indexed or referred to.
As a related question, how to filter out mediocrity. I mention this because your experience, which probably gels with many of us, shows companies should be applying some kind of "fizzbizz" test for these candidates.

For example, a simple question I would ask of business development is what technology (car, phone, public transport tickets, etc.) they've used today, and how would they improve it. If they can't walk through the problems and opportunities, they're probably not suited for a role where they'll need to be pitching ideas to potential partners.

I think we should be careful about the word property. In the case of copyrighted works, you do not own the work, you own the copyright to it. In the same way with patents, you don't own the patented idea, you own the patent. Both of these are abstract constructs that means society gives you certain rights, but do not extend ownership to the ideas. This is plainly obvious with regards to copyright since the fair use clause gives anyone right to make copies under certain circumstances.

Even in the case of land ownership, one could argue that what you own is much closer to a "license to use the land surface" since you can have surface rights without having the rights to mine or drill for oil on that land.

So your idea that property comes about because government says "what else is valuable for people that we can protect for them?" I think is incorrect. Property rights aren't some God-given right, we as citizens agree to handing out the rights to pieces of the commons to individuals because there is some net gain to everyone from this. All of those "rights" you describe are therefore subject to an evaluation of whether they serve society's purpose, and I think it's pretty clear that's a discussion that is very relevant to patents and copyrights.
Good luck. If it doesn't work out, and you haven't already tried this mouse, give it a shot:

The dropdown doesn't have Fiction, which was surprising since that's what I went looking for first. Also, when I figured out that I could click on the "Recent Fiction" heading on the homepage, I was disappointed to see that there was no way to filter down to Literary Fiction, the way most publishers do. Otherwise, all the top items are mass market fiction, which is a very different genre.

I think that your point is legitimate but that you overvalue the value of it. Yes, in that hypothetical situation, the CEO would be receiving disproportionate credit for the success. I even think this might happen quite a bit. But things don't happen in a vacuum. I think that Meego was a fantastic product, the N9 a brilliant piece of hardware, and I think that no matter how much that's true Stephen Elop truly and royally ruined any value Nokia had a chance of creating by pulling a helluvan "Osborne Computer." The ideas and talent were all there in spades, and the execution by the guy responsible for handling the organization's execution COMPLETELY trumped all of that.

Ergo, CEOs actually do have quite a bit of value.

Perhaps you can use light sensors instead? I haven't tested it, but it would seem that something like the QRD 1114 sensor might work.

As for the scroll wheel, how about a thumb-controlled analog stick? (although it would be hard to make that compatible with both right-handed and left-handed people). The main thing preventing me from buying something like that is the lack of a scroll wheel... many applications require one, including 3D modelling software, first person shooter video games, etc.

ah interesting. When I use a regular mouse, I click like crazy - I think more than needed, so that might explain it. For the vertical mouse, I don't find I click as much. fwiw, I also use http://www.marcmoini.com/sx_en.html - which allows me to use the button on the shaft of the vertical mouse to grab-and-scroll windows. useful for scrolling web views, and probably reduces my actual clicking.
Awesome, in theory this is how it should work. I'm actually more curious as to how you handle it practically though. Because for us, validating the receipt from Apple takes time, so if you are first making a request to Parse and then Parse has to make a request to Apple, the added latency poses a real threat to the user cancelling the transaction, especially on a mobile device with a crappy connection. This is why I see server-side validation as non-ideal. But such is the state of mobile development.
Major CDNs do use anycast routing, in conjunction with DNS/geolocation based routing in locations where anycast's results would be unpredictable (usually in locations where there are many POPs.)
355/113 is a convergent of the continued fraction for pi. The convergents of a continued fraction (for an irrational number) give the best rational approximations to the number. I'm teaching this stuff this summer; here's a link to my notes on this:

http://www.millersville.edu/~bikenaga/number-theory/approxim...

For instance, 278/125 is the best rational approximation to the cube root of 11 having denominator less than 155. The proof is pretty easy --- you don't have to do it by trial and error.

As for why 355/113 doesn't come up in other expressions for pi --- I'm not sure why it should. The fact that two expressions converge to pi is no reason that I can see to expect that they should involve the same integer coefficients, say. There are infinitely many integers. There are infinitely many expressions for pi.
That is incorrect.

Tranferring to sf is almost always done as a team move, and they will not let you transfer up to the city if your new team does not already ahave a sizeable contingent up there.

It is not a carrot or a reawrd, it mainly has to do with team chemistry and logistics.
Good question! It's possible that this will eventually happen, but I think it's unlikely for 2 reasons:

Lots of stuff goes through a small area in the carpal tunnel so it's easy for it to all rub too much and get irritated. My understanding is that the extensors don't all go through a similar narrow area so are less likely to have this problem.

The flexors are used a lot for typing. By moving some of the wear from mousing to the extensors, the idea is to better spread out the wear and tear.
Yep. Whatever editor/IDE they wanna use.
It would have been more helpful if you said what kind of development you were trying to do. I'll assume you are talking about web development... Others have mentioned good editors and the such. For FTP I would say Forklift over Transmit, but most of those tools are just preference. Find one that you like.

However, the ABSOLUTE BEST DEVELOPMENT TOOL for OS X has to be Sequel Pro [1]. I have not found a single other program like it on any operating system. I'm serious, I use a Mac at work solely for Sequel Pro, and my Linux box for everything else. If you are doing a lot of MySQL administration it is an invaluable tool. It gives you an extremely powerful GUI along with direct console access. Better yet its free!

[1]: http://www.sequelpro.com/

On a side note, if anybody knows of anything even close to as good as Sequel Pro for Linux, I will literally send you 1 Bitcoin right now. EDIT: Don't say Workbench or Emma, because I've used them and they don't come close.

I want to share this video from Charlie Booker.

Basically at the end the forensic psychiatrist says that giving this intense superficial coverage about the gunman only encourages more copycat killers. I don't know what compelled me to click the link even after watching the video and telling myself to stop following more coverage, but that may be all the more reason why it needs to stop.

I honestly don't care what his intentions are, and I think the biggest punishment to him would be if everyone just forgot his name and he be left to pass the rest of his life in jail sitting in relative obscurity.

Software patent: String length determination on a distributed processing system
Thanks for the ideas!

With light sensors, do you mean that the fingers would normally cover them and when you lift them off the sensors they would detect that? That's pretty clever. Although you'd have to make sure that when your fingers are down, you're lined up and covering the sensor. Maybe the mouse could have indentations which guide your fingers to the right spots.

I'll bookmark that part for future reference.

I thought I was going to hate not having the scroll wheel but it turns out I don't mind much. The only game I've played recently is diablo 3 which doesn't need it, but 3d modeling was a PITA. Maybe I'll try the analog stick idea for version 2.

Thanks again!

I'm sure Craig was speaking truthfully when he made his comment. But he is but one piece of a whole, and that whole includes folks who count the pennies. And business person associated with Craigslist would know that the only value Craigslist has is its listings. Giving those away to be re-used by another web site would never fly with such a person. I don't doubt for a minute when you tell someone is taking money out of your pocket that you need to fund your operations (I know, I know its more nuanced than that but its the gist of the argument) well you an roll over or you can fight.

If they go to court and get an opinion it should be really helpful as a guide for other entrepreneurs who see re-processing the information on the web in new ways as the foundation for their business.
I do a lot of web development so thank you!
Thank you for your thorough reply. I'm going to look into all of those tools.
The biggest problem I foresee here is that there would be no tactile feedback -- it's essentially the inverse of using a touch screen! You wouldn't know whether your "lift-click" actually went through or not, whereas on a normal mouse you get that very satisfying physical click as feedback.

Can anyone think of a way to get around this issue? Very cool idea by the way.
How would you feel about something shaped like the prototype? https://lh3.googleusercontent.com/-CUDaxDwJyR0/UA1sdGipv4I/A...

Hehe.
>> Internal adapters are a lot messier for 120v.
>Why do you say that?

Well, for starters, most for-profit enterprises like to avoid liability. 20 V things are considered "low voltage" for regulatory purposes while 120 V things are considered "high voltage." That has certain implications for how you have to electrically insulate your portable device.

Then you also have to consider the difference between AC and DC. A power supply meant to connect to the wall has to have an energy storage device (usually a capacitor) for the 120 times per second that the wall delivers no energy.

Designing and manufacturing a device to power from 20 VDC (+/- 10% or so) is amazingly easier than one that must slurp 120 VAC.

>Basically you would need 20v -> 5v vs 120v -> 5v - there isn't really a lot of difference

This is completely wrong. 120 VAC is 120 V RMS, which has peaks of +/-170 V. Go to digikey and compare the price of 340V capacitors to 40V capacitors. Then consider the fact that your low voltage capacitors only need to filter relatively high-frequency ripple and occasional step-loads, while your high voltage caps need to supply energy when the wall isn't (so they needs to have much more capacity).
You're jumping to a false conclusion that Go's designers were not aware of those language features, and that that was the reason why they aren't in Go.
same idea. I've tried that design. for some reason I didn't ever feel like I had a great grip on it and pushing buttons right-to-left felt weird to me.

I wonder if you could hack something like this together purely in software using a Magic Mouse, since its surface is just a big piece of multitouch glass. There's still the problem that the physical form factor isn't the most ergonomic, but the barrier to entry for trying it out is pretty low.

"The photos themselves go straight to Amazon S3, which currently stores several terabytes of photo data for us."

That was 7 months ago, so let's say 5TB today. Plugging that into the calculator for AWS says Instagram pays a whopping $500 for photo storage each month.

I don't want to take the time to do it myself but here http://highscalability.com/blog/2012/4/9/the-instagram-archi... someone punches (in the comments) all of their numbers into the AWS calculator. He comes up with 12k per month based on what they've said they're running.

No, this is just semantics.

The point is Google respects publishers' desire not to be indexed. Padmapper does not. Robots.txt is simply a common method for conveying that message. It's not like Padmapper could argue they didn't know CL was unhappy; they got a certified letter!

This is just semantics. Google respects publishers who do not want their sites listed.
Very interesting stuff.

As for sequences, I particularly liked pimasterfromhk's.
I'm getting sick of the general attitude here. A majority of people seem to think that it's OK to copy user posting data from CL, because they are a monopoly. IE is cited as an example of a monopoly, thus anything is OK to take it down.

That attitude is horribly wrong. Agreed, CL is a monopoly. Agreed, they are holding back innovation. But, you don't disrupt a business (and build yours) by copying their data, especially illegally. Although, the legality of issue at hand is up in the air right now, the general attitude is a bit appalling.

What's required is a way for users to post their listings simultaneously at other properties. The content of the postings belongs to the user and they should be free to re-post it anywhere.
