Obviously you have to draw the line somewhere, but if you don't think there are people who are "actually sensitive" to this particular use of language, then you are sorely mistaken.
Why wouldn't you have prior knowledge? You presumably know where it goes - just look at the keyhole. Or if not, a single identifiable object in the photo gives you a lot of scale information. I doubt they're as concerned about white-background newspaper-worthy shots like the NY keys, and more about shots at a distance (keys on a table, for instance).

You're giving those executables full control over your computer. Yeah, you won't get burned very often (depending on where you're getting these executables.) But when you do get burned it's going to be catastrophic. That's the problem.

It's a bad practice.
I recommend you to watch this TED talk:

Isn't that just for cached files anyways? I don't see any documents in there that I actually use.
Yes, "static CGI" if such a thing was a thing :-). I've got a thttpd tree that I do this sort of hack in (these are great for monitoring large numbers of servers for example).
I'm a bit confused what the intended use case is, here. Is the idea to have it loaded on your tablet while programming on your laptop or desktop so you don't have to switch screens? Why not just print it out and pin it to the wall?

Are you scanning / OCRing the documents? I never managed to get the OCR to be good enough for invoicing, there always had to be a manual process to fix the (machine-learning-flagged) errors.

Or don't you need accurate-to-the-cent invoices?
Really? Going to extra mile to support your customers will give you a good reputation. It's nothing to do with playing the lottery. In this case it paid off in a big way. In the general case over the lifetime of your business it will almost certainly help you out somewhere.

I've just finished several freelance jobs where I've made sure to go above what was required. That's several people who will recommend me to others. That's not playing the lottery, it's just a sensible way of operating.

> Having a rake angle on the front wheel makes a bicycle self correcting (if the c.g. is on the right side of where the wheels contact the ground, then a right turn is induced in the front wheel by the rank angle)

No. If you actually read the paper linked (and the Supplementary Online Materials, which contains a lot of the actual information), it is shown that rake angle is not necessary for the bike to be self correcting. You can build a bike with a negative or zero rake angle that is still self-stable (at least, according to the bicycle dynamics modelling software they were using, JBike6; they didn't actually build this particular bike, but did build one that had small negative trail and no gyroscopic effects that was still stable).

As they demonstrate in the paper, none of rake angle, trail, or gyroscopic forces are either necessary or sufficient for self-stability. All of them can influence stability, so saying the gyroscopic theory has been proven wrong is not entirely right either; it is a part of the dynamics that adds stability, it is simply not necessary or sufficient on its own. In fact, the paper shows that on the "benchmark bicycle", removing the gyroscopic force makes it unstable, so on that particular design, the gyroscopic force is necessary for its stability (thus explaining why it was believed for so long that gyroscopic force is what provided stability).

What we know is that gyroscopic forces, trail, rake angle, and distribution of the center of mass of the fork and body of the bicycle all influence stability (in particular, the center of mass of the body of the bike being substantially higher than that of the fork); none of them alone are sufficient to provide stability, and likewise none of them alone are necessary as we can build bikes without them that are still self-stable.
My daughter is 18 months old and has loved my iPad since before she even understood the relevance of her gestures. I think they're a fantastic toy/aid for children.

This was her favorite app for quite some time: https://itunes.apple.com/us/app/i-hear-ewe-animal-sounds-for.... The same guy has a couple other apps that are nicely made.

Would you like a GPS embedded in you? By force? Alternatively you and your wife could practice good parenting and just not let your child wander off alone until he or she is old enough to do so responsibly, at which point a GPS would be horribly invasive.

How does this research _not_ have the goal of keeping humans from doing "wasteful and damaging stuff"? The long term point is to have only a few cows that can create tons of beef without being slaughtered. Sounds much less wasteful, more efficient, and less damaging to me.

If your only other problem with this is that they're working on changing the product rather than the behavior of an entire population, without actually giving a hint on how you would go about changing that behavior, you're just complaining for the sake of complaining.

I can't find anything related to the response headers the server can send to the client, and the OP site just serves responses with content-length, content-type and server. Anyone?
sometimes losing a big client in such way may actually be a way to sell yourself. i.e., marketing yourself (or the company) as the hard-nosed professional whose pride is in the work but will not be pushed over.

Sometimes, such reputation does most of weeding-out of clients with the intention of empty promises. Setting your market value too high isn't recommendable, but setting it high is definitely important.

there are some pretty dramatic counterexamples to your claim.

Valve, of course is the most well-known, but Semco is a large brazilian company that runs this way, as is Morning Star, a tomato processing company in California.

Metrics measurement and tracking of some sort, depending on your area of interest and existing expertise.

I made a similar cheat sheet years ago as a PDF. It got some popularity around the developer community. I think it being html/an open source document, you can use it in many different ways (including printing it out and putting it on your wall). The fact that I have already received pull request I think shows it might be a good idea.
No, it does not logically follow. The attack means that someone who can (for instance) poison the DNS can (for instance) evade CSRF protection for the domains they've poisoned.

> primarily by increasing trail and rake

This is oddly redundant, kind of like saying "primarily by using computers and laptops".

Trail is the tendency of the front wheel of a bicycle or motorcycle to act like a caster. If you change the bike geometry so as to increase trail, the bike will increase its resistance to being turned (steered). This makes the bike easier to handle, particularly at high speeds, and makes it much easier to ride no-hands. But it's not all good: it also makes it very hard to control the bike when the wheel has a lot of load on it (like front panniers) and makes the bike less manipulable.

You can change the trail by changing the angle of the steering column (steeper angle, lower trail), changing the size of the wheels (smaller wheels, lower trail), or adding "rake", which is the forward swoop that many bikes have in their front fork (more rake, lower trail). Though some think rake is to provide a bit of bounce or suspension, it's really not. It's a device used to add trail.
Wake Up and Smell the (Slow) Tests
Hi Gabriel, how will this compare to the other Docker-PaaS projects going on? (Flynn, Dokku). I see the inclusion of Chef as a major feature?
Still not much of an app unless the JS does AJAX, but then it's talking to a server that's running some dynamic process, maybe with DB access etc. - right?
I dont know who the target is for this. But if it's big enterprises, then this might not be as appealing as it sounds. I used to work for Datacert, a legal apps vendor for large companies(walmart, jpmc, novartis etc). They use e-billing with a well defined format(ledes) all items on an invoice is code with a specific code(UTBMS). We used a rules engine(Drools) to ensure proper billing. A proper use for machine learning in legal space would be simulations for different pricing models(Alternate fee arrangements(AFA) in legal parlance). If machine learning could evaluate different pricing models for a given case and provide inputs, that would be a big selling point.
So why store passwords then? Doesn't that also lull users into a false sense of security?

It seems to me you won't make token efforts to protect a user's password because that protection would be an illusion. So you would rather tell them the truth, so to speak, by letting them discover that their passwords are all easily visible by anyone who sits down at their machine. But if that's really the best you can do (I'm accepting this claim for the sake of argument), why store the passwords at all? Just by offering to store the passwords you are lying to the user, and lulling them into dangerous behavior.

Do you have data that users expect the passwords to be shown, or that storing them and making them so easy to see has any positive effect on users' password hygiene or security behavior? As for me, I know never to ever allow Chrome to store any password. Has that made me more secure? And is that representative at all of the standard user? I highly doubt it, but don't have any evidence either way.
I'd love one of these with something like a Pixel Qi screen: http://pixelqi.com/our_screens / http://www.cloversystems.com/SunBook.htm

With just an LCD screen? bleh. anywhere that would charge it well would be nearly unusable. Not a problem if you just want to recharge it while doing something else (and for that it's still a good idea), but still.
A few quick comments:

* Don't waste too much money on the stroller, babies grow out of it fast. Go with a ~$150 Greco one (with integrated car seat)

* Definitely get the Itzbeen (http://www.amazon.com/s/?ie=UTF8&keywords=itzbeen&tag=googhy...) a true lifesaver in the first weeks to track milk and poop times. As a side projects, you can try to rig it so that you can access and download the data it collects over BT.

* Another must is the microwave bottle cleaner, you'll love it when cleaning bottles at 2am

* The classic What to Expect book is good. I would refrain from hitting too many websites, etc., you can get overwhelmed really quick.

* I suggest not using pacifiers. These work great in the baby stage but then becomes a problem as you try to ween them off of it.

The GPS chip is way out, I'd say don't make any decisions for the child that may affect him/her in the future (circumcision may be one exception, depending on your religion).

It's not bad, especially if you can get some help from family in the first 1-2 weeks. You just need to roll with.

I'm nitpicking on a small detail here, but

> • Autonomy-oriented employees may need the ability to work from home, or simply slip on their head phones to tune everyone else out.

It's 2013. Are these really special perks to make a certain kind of person happy? Maybe I'm weird, but to me a company that doesn't allow me to tune out with headphones one or occasionally work elsewhere is like a company that tells me what to wear or tracks office presence hours. Do these, in our field, even exist anymore? (barring Yahoo)

For "Autonomy", I'd rather expect something like having a very large say over what an employee is working on and how she does it.
Thanks for the tip. The GPS bit was more to get people laughing than a real question, but no, I definitely would not.

Co-founder here. Charing a percent of savings is an interesting model. We approached customers with it and they pull back from it fairly quickly. It sets up a conflict of interest in that there is an incentive to reduce more than is appropriate. Our goal is not simply "less." We believe customers should pay what they owe, but not more.

We also believe that the relationship with your law firm is important. Just cutting a bill doesn't help that relationship.

Holocracy as a new form of corporate structure
Actually, the provenance adds way more than 1000% or whatever. That 1000% is the provenance discounted by the chance that it's totally made up and, therefore, outright fraud.

Look at this story: [1]

"As Van de Hoeven recalled, they were sitting in her sun-flooded living room, making small talk about how Zodiac could have been a great movie, had it not been so slavishly devoted to ’70s period detail. When Tarantino noticed the figurine on the mantle, he jumped up from the sectional couch."

That didn't happen. If it had, the figuring could be worth a lot more than $50.

$50 - the new price - is in a lemon market of fake stories.

If they really want to test the price of a story, why not do it in a way that isn't fraud?

Why don't they start with real stories about objects that have actually been verified, in a printed book for example from which they can quote, and then simply do the experiment by not mentioning this true story in some cases and mentioning it in others?

This would decrease the "fraud discount" SIGNIFICENTLY since in the cases where you DO mention the story, you can also mention the references that actually back it up. There's no real chance you're just inventing it. For example, if a distinctive custom object was photographed with Obama, you can link to the photograph while "telling the story".

In the version where you don't tell the story, but only describe the object, you don't link the photographic proof either.

That way you can really tell how much value the story adds, instaed of how much value discounted by the chance (which is in this case the reality) that it's just being made up.

[1] EDIT: for the source I followed their link "The project was so successful (and so interesting) that they have now repeated it 5 times and put all the results up on the web. It is also a book." which links to http://significantobjects.com/about/ - I'm quoting from the first picture I followed on the right sidebar, since I wanted to see what these stories sounded like.

I love this bit: "We set unrealistic goals all the time. But where are we getting these expectations in the first place? Often we choose our goals as a result of looking to the outside at someone else and what they’ve achieved, not inward at what is actually right for us. But there’s no logic in that. What’s right for someone else is almost never what’s going to be right for ourselves. The factors contributing to their successes or their failures will never mirror the factors contributing to our own. So as tempting as it may be to set benchmark numbers based on what someone else has achieved, it’s completely unfounded and can actually be a dangerous path to go down. Be deliberate and honest with yourself when you set goals — especially ones you intend on meeting."

I don't understand why so many people blindly follow the assumed paths of others. Most times, we need to make decisions for ourselves about what path is right for us. That's not to say we can't learn from watching others...just that blindly following is stupid (but widely accepted) :-/
Ask HN: Do you think the Leap Motion launch flopped?
I recently just got my Leap Motion, and after playing with it, I'm deciding to return it. I guess at a very minimum I expected an app where I can use it to navigate my Windows 8 interface (I kind of envisioned using it by flipping my hand up and down to scroll through pages).

Integrating the Leap Motion to the OS seems like a really basic thing, and I'm curious if people are returning it for that reasons or am I being overly critical of an early product?

On Nightly it's even better, it's aggressively compacting memory, it was running around 30% (2GB total) instead of 40+ a few weeks ago. Kudos for their effort. I wish they could replicate a tiny bit of it toward the GUI.
A bicycle actually consists of two inverted pendulums (the frame and the fork) joined by a hinge. And the bike that was stable with no trail and no gyroscopic effects used this to provide stability; the stability was provided because the fork, with the lower center of gravity, would fall faster than the frame (taller inverted pendulums fall slower than shorter ones, which you can easily demonstrate by how much easier it is to balance a long object like a shovel than a short object like a spoon on your hand). This provided the necessary feedback that caused it to steer into a turn in a way that stabilized.

The takeaway is that there are several factors which influence the stability of a bike. We know of certain designs which utilize one or more of these factors to achieve self-stability (and the conventional bike has all of these factors, hence why it tends to work so well), but we don't know the exact set of conditions on the combination of factors which would allow you to characterize which designs are stable versus unstable, without simply trying out any given design and simulating it.
Thanks for the feedback. We have evaluated this type of pricing model, but past experiences in larger settings make it unattractive. Basically the incentive is to reach the threshold, and then scale back just a tad. We don't want to create a bad relationship with a company and a law firm, but we do want to make sure they are paying the right amount. Firms serve a great purpose, and they should be compensated; the correct amount.
Thanks. How did you decide on a Graco stroller versus something like the Snap n Go that just the frame that you can snap the car seat into? I would think I prefer that because it seems more efficient and eliminates the need for a separate car seat and additional bulk, no?
