Agreed. I would fund this on Kickstarter, such stings should be positive externalities in the metro they are set up in. I wonder if there have been any sting initiatives on Kickstarter thus far and what laws would allow for (it's been done before, to catch a predator, anyone?)

A lot of these awesome things (weekly standups, together lunches, socials etc.) are feasible when the team is still small. As the team scales, this starts getting more and more difficult and ultimately, silos form among the different functions (sales/support/eng etc.). Probably this might not be felt to such an extent given that stripe is (and will be) engineering heavy (I presume). But I've witnessed this first hand at the startup where I work. Things were awesome when the team size was about 20-25. As we grew to ~150 folks over the last 2 years, a lot of the things start to break.

> Calories are a measure of heat. Not Energy.

Calories ARE a measure of energy. One calorie = 4.2 joul = 4.2 wattsecond.

A calorie is defined* by the amount of energy needed to heat 1 gram of water by 1 degree celsius under a pressure of 1 temperature. But heat is energy, and a calorie (as well as a joul) are a measure of both.

> So please stop with the "calories in, calories out" simplification.

That part is true: Calories in, calories out is wrong, as has been shown repeatedly over the last 50 years. But somehow it is still the religious belief of many.

I know, but this info isn't correct. The cable operators are fully allowing the networks to stream to "Over-The-Top" boxes gaming consoles and connected tvs. The two requirements are:

1. Full DRM Solution, this mostly means Widevine or PlayReady DRM. This support is lacking on some notable platforms. The most recent Roku devices don't support full DRM the best they provide is encrypted HLS which can fulfill the DRM requirements for some operators but not all.

2. Authenticated Users, Users must be authenticated with their cable operator. This usually means also having the necessary infrastructure for limiting the number of registered devices etc.

These present is a fairly complex infrastructure component from the operators and HBO Go has been leading the way in meeting these two requirements. This is why you can stream right now to HBO Go on the Xbox and on Samsung SmartTV connected TV platform.

I don't say this as an interested observer, but an active participant I run a services company that actively works with Broadcast Networks on streaming to these platforms. We're literally doing this work right now with large broadcasters.

I'm no security expert, but after I saw each new wifi password standard cracked within days of its release, I stopped passwording my wifi and used a little script I put on a home linux server to watch the router and if it spotted any unrecognized MAC addresses getting an IP address from DHCP, it would throw them out within a few seconds.

These days, I just turn on the MAC address filter that's built in to most wifi base stations. Now, unless I've manually entered your MAC address into my whitelist, my router won't connect you. My wifi shows up as "open" to any machine that passes by, yet it won't connect.

Many (most?) of you know more about security than I do. How secure is the MAC address whitelist approach compared to a password approach?
I would be a bit worried if I were a direct Rackspace competitor and using Mailgun, but otherwise this seems like a good thing for users -- Rackspace brings more financial and other resources, and this sale (a safe one) precludes a bad sale which might have otherwise happened (if Mailgun sold to Zynga or something and was acquihired or pivoted to in house, or sold to oracle and only bundled with services.)

I actually had two camping bags and a large roll of foam just for those situations. Usually never had any problems, though I do recall spending more nights at their place than them at mine.

I went to college late (~26 y/o) and by that time I had gotten a bed from somewhere (gift from parents I think). I'm married with a house now and don't live as minimally now, unfortunately.
I doubt they would think of it. Mind you they should sell those generators with GPS included, sealed in. I would buy one.
Actually, what happens is that poor people are afraid to discard their unneeded stuff, because its modicum value is still value. Whereas in the middle class, at the end of the day, 90% of the stuff you have can be thrown away because you can be mostly confident that you can buy it again if you find out you needed it after all.

Most of what us non-poor people can't throw away is either sentimental, rare, or a major investment (a pool in your backyard, for instance) that can't be easily recouped.

In short, if you feel that you have a choice in the matter, that's what wealth is.

A backdoor would very likely get the coder sued, and legitimately so.
I would argue it's often more about falling into the same trap as 'audiophiles' as it is about direct benefits. Few people notice the added weight from drinking 2lb of water but people spend hundreds of dollars shaving 1/10th of that from their bike.
This same concept was debated within the realm of drug trade - which obviously is at a different risk level. With special compartment style locks on a chain, the same concept is possible - without a dealer having to ever interact directly with the buyer. Same concept can also exist for hiding information (whistle blowers hiding a SD card with data, a key, who knows what).

I don't know about SF, but it is not uncommon to see just a bike chain hanging on a post - it just fits in to the environment and no one will notice someone just walking up and taking their chain with the right combination.
I'm not sure how much of an effect a startup can have in this area, though.

This is much more a political and social issue than technological. Startups like Khan Academy can certainly change the way that people are taught and how they learn, but they aren't equipped to change tuition costs.

If you really want to change that, start a PAC and start pressuring elected officials. That's where change will happen.

It has nothing to do with Chrome, and everything to do with 6-weekly updates.

Think of it: You have no way to know, going in, whether the changes in any given update will be big enough to "warrant" a major version change. Worse, what if those features aren't stable enough to release and are turned off? It's very difficult to go from version N to version (N-1).

For these reasons (and others), it's a lot easier for us to unconditionally bump the major version every 6 weeks.

Unless I am mistaken, it should be possible to configure opensshd to first try using keys, then fall back on UsePAM only if that fails (similar to how sshd will normally fall back on PasswordAuthentication).

If not, it might be possible to configure PAM with some sort of keys module set to 'sufficient', then have PAM fall back on two-factor auth paired with pam_unix.

In fact, I'll see if I can get either of those working a bit later today. Seems like it could be neat.
More often they charge 75-90% of its used value, enough of a discount to move it quickly but high enough of a price to avoid looking "too good to be true."
> Tangentially, and pardon my ignorance, I'm not a biker: I can't understand people who shell out thousands of dollars for a bike, are these so much better than a $500 one?

Yes, they're considerably better - the price is directly reflected on aspects such as durability and weight of the components (frame, gearing, wheels, etc). Keep in mind, though, that buying the most expensive bike around just to commute 10-20 miles to work won't be a good investment - you should go for a good quality one when you're serious about long distance training or hard core mountain biking, for instance (usually after you're already practicing whichever style you prefer - a lot of people invest in an expensive bike upfront and never really use it to its full capacity).

(or assemble your own. It's fun, specially for hackers/geeks!)
Yes, I have seen a patch as well that allowed you to require both an ssh key and a password ... it was an old patch, though, and I can't imagine it would apply cleanly to any recent OpenSSH ...

This is on our list to pay for someone to do, and we'll release it when they do ... it will probably be FreeBSD-centric, but if it's against OpenSSH generally, it should be usable by others...
I'm chagrined to admit that this simple approach didn't even occur to me. I'm interested as well; are there any disadvantages to this?

Using pam-google-authenticator does not depends on Google, they just wrote widely available apps and a PAM module[0] that implement HOTP[1] and TOTP[2]. Basically, you have a seed and a counter that you hash together. When adding a device, the seed and counter are synced with the device. When logging in, the server generates the proper code, then verifies it got that code. The major difference between the two algorithms is that TOTP uses time as its counter, while HOTP uses a manually increased counter.

I don't think this argument is correct.

It is true that there is a limited supply of potential breakout startups. But by monopolizing the market for iPhone components, you can only charge 2x-3x times as much for the product. You aren't going to make tons more money, like if you invest in breakout startups.

The point is more that a16h realizes most of its returns through the small percent of startups that do phenomenally well. These startups have a higher expected valuation, because of potential extrema values.

So a16h is trying to correctly valuate the top 1% (for example) of startups, not that top 5% of startups. This means that the valuations (in this example) could be ~5x more than is what is conventional, and still be accurate valuations.

Can I quote you on that when the first "flaw in SMS used to circumvent two factor authentication" article comes out?

A secured data connection is much better than SMS and easy to implement. But this is still a 'something you send' factor, which can be intercepted. A physical token or 'something you have' is more secure, and can also be easily implemented with a YubiKey, a paypal/ebay authentication card, etc.

If you think your data is so valuable someone might install a keylogger to get it, you might as well secure it as well as you reasonably can.

The problem with movie quotes and lines from books is that they're out there in a database somewhere. That means they're not nearly as hard for a computer to guess as you might think.
It does make a very considerable difference, if you're serious about your biking, though. Plus, more expensive bikes are not necessarily lighter - there are many variables involved on the price (wrist comfort, seating type, suspensions, frame stiffness/weight, numbers and quality of gears, etc) - many more than the usual 'audiophile' choosing range.

But yeah, a lot of people buy expensive rides for the looks and have no idea what do do with them...

I've owned Ikea or similar grade furniture for most of my life. It actually bothers me that I have to keep re-buying the same things over and over again. It just seems very wasteful.

More notes on the video:

- Rich's whole view on the world is pretty consistent with respect to this talk. If you know his view on immutability, values vs identity, transactions, and so forth, then you already have a pretty good idea about what kind of database Rich Hickey would build if Rich Hickey built a database (which, of course, he did!)

- The talk extends his "The Value of Values" keynote [1] with specific applicability to databases

- Further, there is an over-arching theme of "decomplecting" a database so that problems are simpler. This follows from his famous "Simple made easy" talk [2]

- His data product, Datomic, is what you get when you apply the philosophies of Clojure to a database

I've talked about this before, but I still think Datomic has a marketing problem. Whenever I think of it, I think "cool shit, big iron". Why don't I think about Datomic the same way I think about, say, "Mongodb". As in, "Hey, let me just download this real quick and play around with it!" I really think the folks at Datomic need to steal some marketing tricks from the NoSQL guys so we get more people writing hipster blog posts about it ;-)

If you were originally trying to point out that all copyright enforcement outside of the West is poor (I doubt it) then you really should have made that clear. In China, the GPL brings no specific problems that rights-holders using other licences don't face. If someone is going to violate the law completely, it won't help if you've made them click through an EULA. I don't think this is really what anyone is talking about. Everyone has copyright problems in China, including Microsoft and Apple.

A web search for "gpl hall of shame" brings up an FFMPEG page so out of date that they took it down and an extremely out of date Busybox page. It also brings up this:

Fact is, the GPL works great and has a great history of being enforceable with plenty of high profile cases.
Most (all?) bikes have a serial number stamped on the bottom of the 'bottom bracket' the part that the pedals go into. These serial numbers are unique per bike brand, but not universally unique.

The serial is pretty hard to remove, without it's removal being obvious to anyone that looks, though the brand can be removed or changed - if that happens the serial wouldn't show as stolen.

If there was a lookup for serials then you could check if the bike was stolen, or if the bike was incorrectly branded (serial doesn't match brand), but there isn't a central place for this, unless the (ex)owner registers it on a service such as immobilise.com
In general, about weight, I agree. One exception is rotating mass (i.e., wheels). A light, well-built wheel handles a lot better than a heavy one. No amount of personal weight loss is going to make up for that.

Beyond mass, the behavior of shifters and brakes on nice bikes is much, much crisper and more predictable than on cheaper models. They also have better capacity for tuning (e.g., to eliminate chain rub, or accommodate a high-range sprocket set), and are more likely to stay in proper adjustment for longer. This makes riding a lot more fun -- the machine is very responsive to your wishes, and you forget it's there.

You probably are aware of this, but I felt a need to mention some of the advantages of a nice bike.
Interesting, my guess would've been that yard sizes were at least staying the same. I've chiefly associated new construction with "further from the city center" (from living in suburban Texas for most of my life until recently) where the amount of available land increases dramatically as the radius from the center increases.

The Census PDF breaks things down into inside- and outside-MSAs, and they've both been getting bigger, but I'm not sure if the MSAs have stayed constant size or gotten bigger themselves...
> Actually, purchasing stolen goods is illegal in most places, full stop.

In my state, the statute says "such person knowing or having reasonable grounds to believe the same to have been feloniously stolen or taken".

I doubt any state makes receiving stolen goods in complete ignorance a crime. However, the stolen goods are generally recoverable by the original owner, whether or not the person receiving them purchased them in good faith.
