Good heavens, I shall be watching this blog for the next few days to see how it goes.

this is class stuff. I shall try the airport shoelace tying problem out on my motley crews next week.
TL/DR: I probably shouldn't have used Rails in the first place, but it was too tempting to roll my own blogging engine. Octopress/Jekyll is a better fit for now, but I do have concerns about future problems this choice may cause.
There might be a hump to get over at first, but I think Markdown is going to be by far the best to go for in the long run.

What did your cheatsheet look like?
Type Systems: Bottom Type
Noted on the ticket, thank you.
Neither would I, but IF this happens it'll be the other way round - Dotcom would be giving Pacific Fibre $200 million. Their spokesman says they need a cornerstone investor with that amount to get the project off the ground.

Sadly New Zealand has very few billionaires, and the ones we do have are very risk averse. They'll pump millions into tried and trusted dairy farms and shopping malls, but won't touch things like Pacific Fibre. Unfortunately the same people run the government, so it won't take the load either.

I'm not going to comment on Dotcom's legal shortcomings, but at least he is stirring up our very staid political and business communities delightfully.
Apple Looking into switching from Intel to in-house Chips for Macs
As for the right dosage of Warfarin, there are genetic tests that allow to make a better initial guess at least in some cases. Genetics itself involve a lot of math, and there's also economic aspects (healthcare costs) on top of that. I hope to see more and more mathematicians and programmers participating in healthcare.
Sure, can't refute that. However it's the same mentality that allows the same, basic vulnerabilities to persist throughout the years. The code basically works so sod it, who cares.

Of course, I fall short of offering a solution, because there is none that doesn't imply writing bug-free code (impossible if it's not trivial); spending inordinate amounts of our spare time vetting this code; or otherwise stopping people from learning in the first place. The other one is to tell people not to use these plugins, or to be more careful, but they need to know what's currently'safe' and what isn't.

I just don't like the mindset that 'shipping' code is the be-all and end-all when as masters of our craft (hyperbolic?) we should at least aspire to more than 'good enough' or 'working', even if it's unattainable.
Any thoughts on frameworks like roots which modify the normal core theme structure?
"In being sued by Apple, Google has obviously become a predatory competitor."

"A judge recently threw out the case citing that Apple knowingly violated the patents and it's clear the lawsuit was part of a hostile negotiation."

"Does that mean we have to return the iPhones and iPads we were given?"
And that's a regrettable state of affairs, if you ask me.
In the long run, I'm a lot more likely to believe ratings which are generated passively (through one's actions) vs. through conscious effort. Humans are unreliable self-reporters, and in a lot of cases have commercial or other bias. Plus, there are lots of BS Yelp reviews, like "I am giving this place 1 star because the server looks like my ex-boyfriend who cheated on me".

On the other hand, just tracking where I check in on foursquare will be kind of boring. Office, restaurants near the office (which kind of suck, compared to places even a few blocks away), airports, etc. I hope they have some kind of interesting filtering to solve that.

What I'd really like is something built on my actual purchasing history, deeper into the venue than just presence. Knowing that I always get a double double or 4x4 at innout is a pretty valid endorsement. Knowing that whenever I go to Apple stores, I buy Applecare for the products, also useful. It's useful (blinded, statistically) to other people, and presumably could be useful from a loyalty perspective, or just for personal purchase tracking, to me. (I kind of use my Amazon purchasing history like that, now. i.e. "what printer do I have in the office, so I know what toner to buy, when I'm not at the office to check".)

A payment provider (Amex for me, or maybe Square someday) is probably in the best position to do this, actually.
Slightly OT, but there are many different layers to advertising. We do CPA - which means you don't earn without performing an action (normally buying something). But your family probably uses Colgate because of brand awareness advertising.

When you are faced with a choice of items for the first time, all those billboards, TV ads, product placements and so on are all subconsciously recalled and push you towards a decision.
they bought it because they don't know what to do with the money, that's it. May be it's too simple but it's seem to be the truth
Wasting your time by writing some tests
It's probably not a clear win in most use-cases.
But I'd say that 6GB is probably more than adequate for casual users for the next few years. (4GB might be enough, but if we allow for crapware...) 6GB isn't top of the line, though; 8GB laptops are fairly common, and even higher capacities (i.e. 12 and 16GB) are available. I am hard pressed to exceed 6GB of memory use without resorting to methods like booting a virtual machine.
I don't think the reason to use LN2 (liquid nitrogen) in extreme overclocking is because of the added heat generation. I bet water cooling (which is very "mainstream" compared to the more extreme solutions) could easily handle the extra heat. Afaik you actually need to reach very low temperatures to get the silicon work properly at the high speeds (I guess it has something to do with thermal noise and conductivity, but that's just guessing).

And that is imho a sign that it's not just a power consumption / clockspeed tradeoff, but instead there are actually limits on how high you can go at room temperature.
Calbear, Thanks. This article was awesome! Elaine had great ideas about hiring at the start, and her (or her fictitious dev's) experiences are exactly in line with my own. Just hoped that maybe there was something else besides LinkedIn out there...
But, doesn't our current system have negative externalities that distort behavior? Or is this just some academic test that is impossible to ever really attain?
schraeds, FYI, it appears that you are hellbanned.
A warning about glib
Hear hear! AMD's always been pushing the limits, Intel cleaning up afterwards and making more stable chips based on AMD's innovations.
I think there was a story like that on frontpage of hnews few days ago.

I just think that once a service is as big as google/facebook, these things just happens without malicious intent. Especially if you have a culture of "hack first, worry later" as Facebook does.
Not till the day where we see Android based tablets littering nearly every good TV show and movie. These lawsuits and such are meaningless to the coffee shop / college crowd. Apple is as much an image thing as BMW cars were for the previous generation.

Far too many think that their phone, tablet, or laptop, confers status. That is going to take a lot of work to overcome that attitude. The marketing and product placement that it took to create that is the real power of Apple
Could you imagine the impact it would have on traffic if every car accident had to involve radiation containment? Why would you support this? It could take hours, or perhaps millennia, to clear the road.
That's a great use of machine learning and precision/recall stats. Exactly how it should be done!
Wireshark is really useful, but it's also had security problems (I think I'm not being unfair here) continuously over its entire existence. I started using it over 10 years ago back when it was called Ethereal, and I feel like I've seen probably hundreds of Ethereal/Wireshark security advisories in that time.
Microsoft to retire Windows Live Messenger in favor of Skype
Really great list of gotchas.

I have been using MongoDB for a long time, unfortunately mostly this has been small applications, so you don't really get to test how MongoDB scales.

On that same note, I would love to see a list of gotchas for Riak (assuming some exist). I keep hearing recommendations for Riak, it would be nice to know how it fares in a large production environment.
I saw Kevin Systrom speak at Pando Monthly and he was asked this question in the QA, how they were doing to deal with developers and whether they'd be like Twitter (to which everybody laughed, but the question asker didn't expand).

Systrom said that they very much wanted people to do things that they themselves don't plan to do. He gave the example of a company printing photos to t-shirts. He left it mostly unstated but it was strongly implied that where their product goals are the same as what people are developing with their API, they'll have no reservations competing with people - or even forcing them to stop doing things.

So ya - if you want to be an Instagram developer it would seem the correct strategic path would be to do things they aren't doing and will probably never be interested in doing.

Kudos to Facebook for not falling victim to the innovators dilemma, and allowing Instagram to develop into a service that could very well end up killing what we know as Facebook today.
True, but Apple does not have the corporate stronghold that Microsoft did/does although you could argue the App Store point. Also the upgrade cycle in the Apple profit center (iPhone) is only 2 years and is going to get hit hard by the lower ASPs that phones are seeing. I shorted at 674 (http://seekingalpha.com/article/839661-the-iphone-s-growth-r... - I'm dude111), and am going to continue to hold the position for now. I think the holiday quarter is going to be much weaker, in terms of profits, than anticipated.
Illiterate Ethiopian kids hack Motorola Xoom
Betting against Intel in the long term doesn't seem to be a good idea. That said, I'm sure Apple's got their eye on the world's first 24-hour laptop, and I'm sure ARM could help them get there.
Foursquare Explore now has ratings powered by where people actually like to go
I wonder if that really adds much information value in the grand scheme of things. Yelp is built for ratings and reviews and I can't see myself making the extra trip to Foursquare to see how its users rate something when Yelp will be far more useful.

But what 4sq has that Yelp doesn't is number of visits (per user) and time-relation of visits between places. Instead of ratings, a metric unique to 4sq would be repeat visits (cleaned in such a way to eliminate superficial checkins) and where people go immediately before and after visiting a given place. I would rather see that kind of behavioral data leveraged more than have one more place where people rate things
It's a little weird that it's written from the perspective of the meetings.io folks who are joining Jive, and then signed by someone from Jive. :)
Heh - yeah. We chose our name ages ago (no real reason behind it other than the domain was available), but we figured there wasn't much overlap (we did rename our main javascript file from ember.js to pineapple.js just to reduce potential confusion though).
Right. Apologizing is not strictly necessary. But relationships matter; in the long run someone who is able to apologize and keep calm despite others' rude statements is going to be better off.
Are you kidding by using the word "stole"? Doesn't instagram have the right for building a web profile page for each user with the photos it acquired? Ok, your service is nice too, but as i see examples of instagram pages, their service (at least design) is way too better than yours. Don't get me wrong, if i were you, i would be pissed off too. But there is nothing stolen from anywhere. Take a step further, build something adds value to an existing product, like you did before.
> I would rather see that kind of behavioral data leveraged more than have one more place where people rate things

FTFA:

> The data is based on a bunch of data that Foursquare collects, which it says result in more accurate and varied results than the typical ‘other site’, where ratings can all meet in the middle.

You basically just asked for exactly what the article infers that they're doing already.
"I am giving this place 1 star because the server looks like my ex-boyfriend who cheated on me".

Hardest I've laughed in about a week. +1

I guess the problem is that objective information is hard to standardize in a reviewing system. Plus, I've actually been wondering whether humans would view objective statistics with more faith than human reviews - no matter how ridiculous they are.
Do a grep through this thread for my userid. I've made my argument in several places. Basically, acquiring human status requires interactive and consensual participation in a relationship/society.

Exhibiting some rudimentary social behaviors doesn't qualify as accepting the responsibilities along with the rights accorded with status.
The problem with low molecular weight gasses is that they lead to embrittlement of any metal in contact with them and that they leak past your seals something fierce. Both due to their small size.

He2 is also very expensive and H2 is very reactive which is not good either..
Kickstarter CEO: No IPO for Us, and No Equity Crowdfunding Either
Yes he addresses this. If all you do is make things more efficient then you have no where for the displaced to go. That's why transformative innovation is needed and is currently missing. Transformative innovation needs a longer time to grow so it needs longer term investing before seeing a payout hence a retooling of our tax system that favors investment for the longer term.

We know there is a problem related to new job growth, he mentions that its taking longer for our economy to recover from the last recessions. And, he points out exactly what is missing from that economy too.
I wouldn't doubt it. I think that Apple's going to move to control the entire stack from bottom to top.
This[1] seems to be the fork most people are following these days.

I disagree. I know I'm on the fringe but I make my living as a writer and 100% of my work is written in Markdown (MultiMarkdown, actually) that I then convert to HTML to paste into WordPress. Is it perfect for everyone, no, but for the subset of users who want to roll their own server setup and still have an easy-to-use publishing platform, it sure does fill a lot of boxes.

Moreover, I can teach people Markdown 10x faster than I can teach them CMS-specific HTML rules. Moreover, WordPress's TinyMCE stuff can break quiet easily (we have to disable it for most of our writers, I'm still allowed to have it because I never use it), so having a readably syntax AND having an instant-preview seems pretty perfect.
You might be overfitting the data. The initial series A, and B were essentially a seed round. I can tell you, this was certainly an upround!
We use many dozens of signals to determine venue quality, not just raw number of check-ins.

And there's definitely manual rules for offices, homes, airports, and other categories that receive disproportionate numbers of check-ins.
I was suspicious the first time this hit the homepage, but twice? Are we sure the author isn't manipulating things somehow? He has been publicly promoting his track record of screwing people over to get ahead an awful lot.

Edit: to add a bit of credence, Thun (above) seems almost exclusively to pimp Alex and his company with these bland comments. I don't doubt they're different people, but he doesn't disclose his relationship with Virool very clearly.
Thanks for the feedback. I tend to agree with you about the fact that the analytics and backups offered are not new, but the accessibility to designers is, and I'm glad that you pointed it out more explicitly than I have -- especially given your experience.

I also think that in some ways, the 'usability' of each technology is the big hurdle that must first be cleared before "marketing" becomes the key differentiator. I approached this with the thought that among the existing (or discussed) technologies, any improvement in the technology or functionality is, at best, incremental. That, along with some other factors, is why I suggested that marketing would represent the key differentiator. Glad to hear other thoughts on that, too.
Prior to the introduction of the Federal reserve system which would be 1913. And prior to 1913 boom-bust cycles were more common and quite harsh. I think that's what he's referring to. As to 50% fluctuations I can't say if that's true or not, but I know busts happened much more frequently and took much longer to work through.
Resistance is futile. Yet, they resist
What I enjoy about the NYT interactives in particular is not just their technical sophistication (which is formidable given that the creators of Backbone.js and D3 are among their employees) but the sophisticated information design. There's rarely a graphic that is made to show off bells and whistles. The NYT is far and away he closest to embodying the Tufte spirit and thoughtfulness online, given that Tufte has said very little about best practices in interactives
It seems to be a pretty common senario; people thinking X new technology that Y large site used will solve all of their problems magically. Comparing MongoDB to others; it's similar with Redis and from experience less so with Cassandra (probably the steeper barrier to entry) / Riak (lack of commonality with a standard DB is way more obvious) / Hbase, etc...
Guess I'll have to buy the White Album again …

Or something like that.
Where did this idea of Apple paying nothing for the patents come from? I've never heard anyone suggest that, and it seems completely unrelated to debacle's comment.
Foursquare ratings are indeed based on these kinds of implicit signals that we can infer from the data.

There is currently no way to explicitly rate a venue on Foursquare.
For reference: Apple is willing to pay a maximum of $1 for patents that make their device a functioning phone. Two years ago, they offered Samsung to license some of their less important patents for $30 per phone and $40 per tablet.
Hubway Data Viz Challenge: Submissions
I'm not sure if they are still doing it, but they used to work on the highest voted stuff as a priority; so if you want a feature, vote.

Also, I'm working on Snappy compression with Mongo (it's already used for the journal), however it's not currently stable and work is sporadic due to my startup.
Intel hasn't been doing to hot lately; wall street is definitely betting against them now, and I think they are taking a long term outlook because Intel still has good profits.

What makes you think Intel will eventually stop the slide and get its mojo back?
Sorry, I didn't link to the source originally and it looks like I can't change the URL, but here's the (longer, more interesting) Bloomberg article: http://www.bloomberg.com/news/2012-11-05/apple-said-to-be-ex...

Strange as it may sound, I wouldn't select solely on the basis of strong programs. You're not trying to hire the program. You're trying to hire a person, one at a time. I've met Stanford graduates I wouldn't hire, even though their programs are world-class.

The millennials you're trying to hire have a large component of reactionary talent. Among this subgroup, they don't go out to seek the best offers, and they often settle for lesser offers. You kinda want this subgroup because they're less likely to leave your employ for the next better offer elsewhere.

I've met some sharp people from schools like Dickinson State. I'd pick a community where the school's graduates have nowhere close by to go (and are thus hireable, prone to considering your relo offers, and have something to prove that Stanford grads don't). You'd be amazed how many CS graduates are working at Best Buy or Radio Shack because it never occurred to a development firm to interview them.

Maybe I should be a recruiter.
It's not, that's just press information.
Your calculations appear be within an order of magnitude of correct :-)

One other way to think of the number of shipping containers needed: actually the average american home uses 30 kwh/day. At our target energy density and efficiency we've been attempting to reach 30 kwh per m^3. 1 m^3 is approximately the internal volume of a refrigerator. So each home gets 1 fridge worth of storage. Not so bad ;-)
There's some chinese comp selling $130 quadcops, linked to from diydrones
It seems risky to invest so much in your own chip design without owning a fab too. If they really want to go down this route, I'd expect a purchase of TSMC or similar. And you're not going to stay competitive for long unless you invest heavily, at least on the scale Intel is. Apple users have watched their computers slip behind before with PowerPC, I'm not sure if they'd have the patience to see that happen again.

I could definitely see them going ARM in the MacBook Air line, but I think they'll keep Intel for a while for their desktops (power usage isn't a concern) and the MacBook Pro ("pro" users will need the extra power and compatibility of the Intel chips, at least in the near term).
From the Kickstarter:
"Why are your props upside down?
The inverted props give an efficiency gain proportional to the amount of obstacles in the air column. We've found it varied between 10-20% depending on the frame and protection ring design. The inverted props also let us put the props right in the middle of the center of gravity for awesome control response. Even better, with the props on the bottom they keep spinning when you run up against the ceiling making flying indoors a breeze."
No arms in downwash, closer together (when all copter electronic parts are on the topside of the frame) ... plus you might be more likely to hit the ceiling indoors than the floor.
I remember meeting one of the founders at a party back in March, I think it was a week before they launched. Well done guys!
You can play that game all day. Counterexamples: Mint.com. YouTube.com. Salesforce.com. Wordpress.com.

The fact is that you can succeed with a totally random domain name, or one that just screams your targeted message. This business could work with either as well.

Although if the OP does decide to try to monetize as B2B by selling to landlords, maybe using a Monty Python reference is not the best approach. Also, I might go with a blurb more descriptive than "Make your apartment gate awesome."

But you know what they say about advice on the internet!

Do remember that half of all developers are below average/median for the relevant group. (See also "perpetual intermediates".)

My experience has been in forcing developers to use guis to do commits. It significantly improved their commits because they would browse over the changeset, could commit only specific hunks, didn't accidentally include extra gunk like test files, and generally made better messages.

It is certainly the case that the cli tools give experts the most power. But that power doesn't need to be exercised by everyone, and not even by experts on every occasion.

I would much rather my developer's heads are full of things relevant to the problem being solved (which is what pays the bills) than intricacies of cli tools.
