HP Could Revive The TouchPad, Says Former webOS VP
What a sad idea. That's exactly what I _don't_ hope for.

- No, Google shouldn't get WebOS. I lose confidence in Google every day..

- No, please don't rip WebOS (the IP) apart because of patents

- ChromeOS is more of a joke than WebOS ever was and is really the project that should die to bring more resources to Chrome or Android. What a waste..

You're making sense, maybe, from a business point of view. But for me this is just crazy and falls into the 'let us buy out a start-up, bury anything they did so far and hope that the people stay with us and work on other things we consider cool' category. Which works, sometimes.

Still - I hate those 'solutions'.

How are they different from OpenID?
I'm interested - where did you learn that ActiveRecord does not require IDs?

The only case where I can think of where it doesn't require IDs is when building a join table (for a many-to-many relationship).

In every other case, you need to specify a primary key field (although it does not need to be an auto-incrementing integer called "id") and I'm sure it says as much in the docs.

EDIT: You can do a select and omit the ID field in the resultset, but you cannot save the results back again - simply because it does not know where to write it back. Again, I'm pretty sure I remember reading that in the docs, but I may have imagined it.
Are we gonna do this? I took AI in college but it was so-so, and I was thinking about doing this again. Anyone in a similar situation?
From that same SSRN FAQ page, http://www.ssrn.com/update/general/ssrn_faq.html:

"We have entered into a variety of relationships with the publishers to provide access to their fee-based research through the SSRN eLibrary. These papers are identified by this icon: Incl. Fee Electronic Paper (a red dog-eared page with a "$"). If you are purchasing a fee-based paper, you will click the 'Add to Cart' link and be linked to your Shopping Cart."

So they run as affiliates for paid-for papers.

They also run a job listings service.

You noted already the ability to get a printed and bound copy of a paper on demand.

Edit: without looking in detail it seems those running the service are probably supported by academic institutions [for other work that they do?].

Indeed, it's a weird way to pose this. As I recall, it was never the company or their specific voting machines that was the subject of discussion, but rather the idea of using closed (and thus unverifiable) voting machines produced by a commercial company for general elections. Stating that this makes the company evil or unreliable seems a bit dishonest to me.

Full disclosure: I am a former employee (I worked on the product mentioned in this article), but I joined the company much after the voting machines were in the news, so what I know is pretty much what was in the media at the time.
Separate to Vim, this concept should become more popular. Real world conferences have their place, for sure, but some topics are avoided as they probably wouldn't break even, and seeing more things like this would be great.
Bing looking for a Node.js engineer
The OP would do well to read "Walden" by Henry David Thoreau or, perhaps more pointedly, read up on the teachings of Epicurus[1]. And, more generally, I highly recommend "The Pleasures and Sorrows of Work" by Alain De Botton. And then there's the defining entry from 1960's philosophy, "Zen and the Art of Motorcycle Maintenance" by Persig, which is precisely about the intersection between nature and technology.

These concerns with modernity go pretty far back in our history, and some very smart people have come up with workable solutions you can adopt as an individual without needing to go change society.

I went through the scanner a few weeks ago.

I was a bit jetlagged so I didn't raise my concern quick enough, which I fully admit is my fault.

They basically herded my fiancee and I through the machine without telling us what it was or that we had any option for a pat down. That's what bothers me the most I think. They seem to be ok with subjecting people to this without telling them or presenting them with the choice.

After careful consideration being molested by the state would have been my preferred method of security authentication, given the opportunity.
Works when its just you and friends, and you talk a lot, and are working on the same project and release schedule.

Change any of that, and you need a better technique.

There are lots of different ones, and switching between them is a mind-bend, so folks gripe a lot. But you'll likely have to learn one sometime, probably sooner than you'd like.

Please don't be the guy that gripes and drags his heels. There are legitimate reasons to need source control. Your personal convenience is one of the decision factors, but a very minor one.

Just stating that it is P2P doesn't necessarily mean this. If there were skype servers that handled everything except for the actual individual call, and the individual call was in a connection directly between two clients (not through a server) and that would be enough to be able to say "Skype is p2p".

The interesting thing about this otherwise misguided post is that there are now people who started out on Git who are struggling to adapt the older, server-based workflow.

It's really not about Git vs. SVN. It's about distributed vs. centralized VCS. I think programmers are realizing that there's truly an advantage to the DVCS approach but the discussion quickly becomes emotional and irrational. The net result of sucks-vs-rocks discussions are just damage to the cause of newer technologies.

I've used RCSs (RCS,PVCS,VSS(^%$#^$%),MKSSI,CVS,SVN) for so long that the latest versions of SVN, which support branching (though not so well), seem very comfortable and luxurious. The Eclipse plugins like Subclipse or Subversion for updating and merging files make CVS/SVN almost is a pleasure to use.

However, there are workflows and tasks that DVCS systems support much more naturally and it's that aspect that should be discussed.

don't most people use their ISPs DNS servers, making this mostly irrelevant?
Thirty years of use and demonstrable, well-documented lack of increased cancer rates in the users. That's why it's irresponsible to use them for political reasons. Or are you among those people who think they make you more secure?
That's what dotshare.it (no affiliation whatsoever) is for. The whole idea sounds nice though.
Totally agree Peter! Having given a couple webinars over the past few weeks, I think there is still a lot of room to grow for these types of online events! I'm hoping this sparks interest in other online conferences in those smaller niche subjects that historically may not have drawn a crowd to a physical location.

Ask yourself how much time you'll need to invest (up to when it becomes self-sustaining). Multiply that be a reasonable hourly rate. Compare that the the $$$ + time the other founder is investing.
In what sense? It's easy to change DNS servers.

Or do you mean that ISP DNS servers are generally close geographically?
How does it compare to node.js? When is cramp a good fit compared to node.js and vice versa?
Worry about the money second. As the technical co-founder you'll be contributing half of your time to the venture.

Ideas are worth absolutely nothing, try selling one. Don't worry that it's his idea, the idea SHOULD and WILL evolve as you develop it, and the idea will then be both of yours.

Money obviously has value, but at this stage of the venture, it's too early to size it. He should loan the money to the company in the form of a convertible note (giving him a nice return on his money) and valuation will come down the road when there's more transparency. You should each split 50/50 the equity, with him holding the debt. Anything less would be unfair to YOU.

Let the equity vest based on hours worked; that way, if one of you goes from 20 to 60 hours, it's much easier to figure out how that works ahead of time.
This is pretty interesting, and I've never heard of it before today. However - I am a little worried that this seems to allow anyone that enables this option to track all users that make DNS lookups. And it doesn't say if there's a way to disable the behavior, short of switching to a DNS server that doesn't do this.
So, the solution is to quit the app, right? Simple enough.

Of all those companies I think I worry more for Zoomshift than any of the others. Having worked in the restaurant business through middle and high school and part of college, every owner has slightly different rules around trading shifts, scheduling, etc.

Maybe they have a crazy customizable rules engine that owners can easily configure their own rules - that would be a killer feature. Without that I'm not sure they can break into many small-to-medium sized restaurants.

The other killer feature they could implement (if they don't already have it) is branding customized for each restaurant chain and/or owner. If your local restaurant that has 8 locations could get a customized version of Zoomshift for a reasonable monthly charge, had customizable rules and incredible support - that would be a no-brainer for most restaurant owners.
the latter, e.g. I'd assume an competent ISP with a large customer presence on the west coast would have DNS servers for their customers on the west coast, or just use anycast...
Sounds like you're doing all the right things; now it's about content. Submitting to HN will always give you a little spike, but if it's something interesting that sparks debate you'll stay on the front page, get people tweeting about it, etc. and maintain that increase for a much longer period.
I've been hounding /newest pretty regularly for the past couple weeks as well, and it seems fairly steady..

I don't understand why people keep bothering, as there's no way it's showing results. I'd assume HN is wrapped into some brilliant-auto marketing package somewhere.

Last I heard, the magic number was 5 flags within an hour, so I think we just need more people actively flagging.
Being able to use a radio to know who voted what because of electronic interference emitted by a voting machine is not just a "closed voting machine by a commercial company" problem, but one of pure negligence, ignorance and poor workmanship. If you design a voting machine, you design and test for those requirements.
>This is just another blogger to piss on Spotify for some strange reason to the point where they make up stuff.

Actually he discusses his reason, right there in the post. Spotify used a lot of his bandwidth with no way to throttle (as others on this thread have discussed), in a way that he didn't feel was disclosed up-front.

It's great that you love Spotify and get value from it, but don't jump on this board calling someone a liar and questioning their integrity because they don't get the same value from it.

As long as we're playing the one-downsmanship game, I'd rather use Clearcase than Serena. At least if there was a big enough set of servers to run the VOB and view server functions for Clearcase so that it responded. The funky virtual file system in Clearcase does take getting used to, though.

That said (ramble here...), I've Used RCS, Clearcase, VSS, CVS, MKS, SVN, Git and Serena. I like Git best, but SVN just isn't all that bad. It works plenty well enough. Never had reason to use Mercurial yet...
In fact, that's one of the reasons I'm working on building CastingCode.tv (http://castingcode.tv) as a platform to serve both ad-hoc and organized live coding events to the web. :)

It's a great fit when you need to use your existing Ruby code. Active Record models for example. It works very good alongside async sinatra as well.

All said, it all boils down to your personal choice of languages.
The point of observing that wind kills birds is more to shake people out of thinking it's a matter of "green = holy = perfect" vs. "conventional = evil = bad", and returning to thinking about costs, which are never zero, and benefits, than specifically about birds themselves. Once we're back in a frame of thought in which costs and to a lesser extent the benefits aren't being manipulated behind the scenes to produce a pre-desired result, and once we're back in a frame of thought where we once again remember we're talking about powering a civilization with these power generation methods and not just abstract numerical "houses" or whatever, we can have much better and connected-to-reality discussions on the topic of power generation.

Unfortunately, wind doesn't hold up very well under such examination for a variety of purposes, and I seriously doubt this changes any significant aspect of the analysis. But that's not the "evil's" fault, it's just engineering.
>This is just another blogger to piss on Spotify for some strange reason, to the point where they make up stuff.

Why do you assume that, just because upstream traffic is not high for you, it isn't for anyone else?
Agreed. The middle ground is where we have to deal with real data instead of justifying our preconceived notions. I think that is what the OP is trying to do with his post - a call for existing studies and data.
In addition to the radiation risk from the Rapescan machine (and the potential problems of overexposure raised by the OP), you also need to consider the extra radiation exposure you get from the flight itself. Some numbers here [1] and a calculator here [2].

This is simply a consequence of the fiscalization of academic values, and doesn't just apply to libraries. Professors need "high-impact" papers to justify their grants so they can get more grants. The fiscal imperative to acquire grants is very strong, because grant overhead is a major revenue stream for the host institution (probably THE major stream.) It's much easier to have a high-impact paper if you publish in a famous journal, so everyone shoots for Science, then Nature, and on down the hierarchy as their field sees it. And they will eat just about any kind of shit to get published there, including having their papers locked behind a paywall. Because they are plugged into a system where getting grant money takes priority over advancing knowledge. Don't get me started on how this skews research priorities and experimental designs...

Simple & Painless Way To Do Android Database Development
He brushes off "utility-scale storage" but to actually power the country with wind, storage is a big problem. He mentions batteries. The cheapest battery is lead-acid. Here's an estimate of just how much lead it would take to run the country on lead-acid batteries:
http://physics.ucsd.edu/do-the-math/2011/08/nation-sized-bat...

Short answer: 50 times more lead than exists in known deposits, and $25 trillion dollars.

That's probably an overly pessimistic estimate. He assumes that we have to handle the wind stopping all over the country for a week (or, equivalently, going down to 30% for ten days). But I think it makes the point that renewables can't take over until we figure out scalable storage.

I did see one interesting idea: go someplace with lots of solid granite bedrock. Carve out a giant plug and store power by using hydraulics to raise the plug.
http://www.solarserver.com/solar-magazine/solar-energy-syste...

That article says claims that "an analysis of a future of renewable energy shows that a mix of wind and solar energy needs, at least, a two day storage capacity." With that assumption, two plugs of 500m radius and 1km deep could handle all of Germany, at a cost of half a euro per kWh.

On the other hand, my ex-geologist brother was fairly sceptical of this idea.
Signed up. Id like to use vim since i like the concept but it seems so damn hard to get into. The post yesterday "learn vim progressively" was interesting though.

Catch a Cheating Spouse with GPS Logger
Yeah, not sure. I think most ISPs use just a couple of DNS servers for their entire network -- or at least that's the case here in the UK. But as you say, anycast might mean that those two IP addresses are actually represented by many servers.

I guess we'll need the input of someone who works at an ISP :)
This is something I would use. I tried UPCDatabase but half of their information is wrong.
Perhaps, but I wouldn't use that as a starting dataset; noise resilience and a training set for enhancing this functionality is surely better developed on top of a working implementation for a lower-noise input? Better to build the easier solution and reinforce it for hard problems than try to go straight at the hard problems.

Put it another way; which would you start by teaching a student: the easy situations or the more complex situations?
Where you forced through the scanner or did they offer you a choice?

As for UK airports. They seem to have a rather inflexible approach as DO AS WE SAY, OR ELSE! Haven't seen them in London City Airport, though.

I could also imagine that Amsterdam only channels US travelers through the scanners. In Zurich airport the US airlines essentially have half a terminal building reserved for their flight operations during the morning hours. I haven't seen scanners there, but flying mostly within the Schengen area I wouldn't necessarily know.

Indeed. What I'm reading is, "Google Public DNS and OpenDNS are relatively centralized, meaning CDNs might deliver you content from a cluster in Great Britain rather than your home country Germany because your DNS server is located in London. Now, you will get content from Germany again." The article makes it out to be something fantastic and exclusive to these services when the news is actually that these services used to have a big problem in this regard, and now they're working to fix it.

Freecycle already have an international website that you can use, http://www.freecycle.org/.

However, and it's a biggy, the individual Freecycles act automonously to some extent and some choose to stay as a Yahoo! Group instead. If you want to watch several groups then this is annoying.

Rant:

Freecycle lost its charm for me when I got booted out of a group for being in another group. My local city is poor and we get posts like "old pyrex oven dish, only a few breaks, lid missing, needs a good clean". Because of that I wanted to belong to the next City's group where the rich people get rid of stuff you'd actually want. But apparently that Freecycle is all about ensuring that poor people don't get nice things ... grrr. I contacted the central team about this and they said, roughly, "some groups make up their own rules that differ from the objectives we claim to work by, sucks to be you".
