Indeed, it seems rather tragic to see initially good ideas worked into a dogma.
Oh you mean that hacked up version of AOSP by slang-talking enthusiasts often missing the proprietary drivers needed to use things like 4G, GPS, and the device's camera? The one that includes the wallpaper with the scantily clad women in breast-exposing football outfits?

That ought to go well with the IT folks at the office.
I've been doing "post-it driven development" on my own, using my monitor bezel. It seems to work until the stickiness wears off and the task becomes lost forever. Oh well.
Except much of the good Android parts, hardware drivers, and applications aren't actually open source. It's a nice pipe dream, though.
"Basically, this article is about optimizing the developer experience rather than the user experience."

Did you ever use Bugzilla? Nothing is more detrimental to the user experience...

Users would rather send support e-mails or use phone support. For the lack of that in open source project, keep bug trackers simple. E.g. Github's bugtracker is quite ok, it is fine for writing a bugreport and reacting to it. But doesn't have all the bells and whistles that makes it complicated for users.
I'm much more a fan of using justified text with a minimal amount of hyphenation and word-splitting used only for really long words to prevent jarringly large spaces between words. Justification in general looks and reads fantastically well, but I agree that a lot of hyphenation and word-splitting makes it worse in both cases than a ragged right edge.
"It could be a core Cassandra problem, something they added, or completely unrelated to Cassandra; But the internet doesn't care. It's drama at its finest"

Digg made a big deal about their move to Cassandra (just as Digg's move to Cassandra was used to legitimize Cassandra, and by correlation NoSQL, among a wide range of zealots), going back over a year.

The thing about talking big like that is that it often comes back to bite you in the ass if things don't go well.

If Digg quietly released a new version that worked more reliably and provided a better experience, they would have been in a perfect position to pontificate on technology.
This will be great. I've been using zsh for probably a year now but I'm definitely underutilizing it. vi mode for zsh seems to be better implemented in zsh and thats something I could definitely not survive without.
I don't think it's incorrect. But for constant velocities it is canceled out because the relative motion causes things to also appear in a different direction. This happens with ordinary light, also. Stars appear in a different place to us because of our relative motion (they appear to be located more "forward" in our direction of motion).

As as example, assume there is a star directly perpendicular to our motion (and that the Earth moves in a straight line). Due to the vector addition of our motion and the light travel direction, it appears to us that the star is located slightly forward of perpendicular (typically by about 1/100 of a degree) Now assume the star were to disappear. During the light travel time the star would have time to move backwards as seen by us (due to our forward motion) so that at the moment it disappears, it appears to be located perpendicular to us.

In the context of gravity, this effect (it's called aberration) exactly cancels and the net effect is that the gravitational attraction is in a direction different from the actual location of the attractor such that it appears that gravity is instantaneous.

This only works for constant velocities, once you have accelerations it becomes more complicated. And it's not a relativistic effect at all, it's present for all waves with finite propagation speeds. You can do this experiment with boats making waves and get the same result.

Edit: And your charge example is not so good. For Galilean invariant theories it's only relative motions that matter. There is no effect if the two are moving with the same velocity. (Plus, once there are relative motions between the charges, there will be induced magnetic fields which affect the dynamics.)
Building Web sites optimized for the iPhone and Android
Stop this shi7 before it gets out of hand.
My favored point on that continuum is to skip the 'various addons and plugins' and just apt-get install zsh on all my machines. To skip zsh altogether seems like throwing the baby out with the bath water. I tend to think of it as a better bash implementation.
Exactly, this is very relevant. The type of person who stumbles upon your web app is isn't necessarily the type of person who decides a good use of their time is completing mechanical turk tasks. But as long as you're aware of this when considering your results, I suppose they can still be considerably valuable.

I don't know if hyphenation should be automatically on just because justify is, but a separate CSS property, or a hyphenate option on the "word-wrap" property, would certainly be a more elegant solution than all of these scripts.

why are you trying to save db on my disk?
This was new to me. I wasn't passing judgement, but it may be a sign of things to come.
I'd love to hear more about how you navigated this process. I had just assumed it was "impossible" unless you are Boeing or Halliburton.
The article is not specifically about bugzilla, but issue trackers in general.
all your db are belong to us?

but seriously, what?
Hmm. Now I need to think about it a bit more.

Suppose we have a scalar field.

For Galilean relativity, a sphere expanding at a given speed will remain so after a boost, but will have a net velocity. Densities will remain the same. A moving source shouldn't matter -- any material will itself will set the rest-frame, and must to have a non-infinite propagation velocity. Whereas, emitting particles, these will have the velocity of the source. Ah! if it's a complex wave equation, you can put a varying phase on everything encoding the velocity. But moving to a complex field is in some sense putting more degrees-of-freedom in.

For Einsteinian relativity, a sphere expanding at light speed remains a sphere in any reference frame, but the density along it changes. A moving source should have that same pattern, so it would seem that local differences (i.e. derivatives) could "point out" the velocity of the source. This behaves the same for particles being emitted. Is there a first-order Lorentz invariant scalar wave-equation, or only second-order, using the d'Alembertian? And that seems to introduce another degree-of-freedom as well.

I'm still really confused. How do pions behave? Is it reasonable to consider them as a fundamental scalar field when they're modeled as pairs of quarks? Particularly when they have excited states that are spin-1?
Absolutely — return the favor!
I hope Hurd wins. Not because I like the guy, but because I think non-compete agreements, like patents, must go down in flames.

'Slow Light' on a Chip Holds Promise for Optical Communications
That article misses some obvious possible hands Ivey could be putting Booth on. 4-5 for the straight, or something like 8-9 of diamonds for the open ended straight + flush draw.

Ivey obviously can be intimidated. I was watching and playing a lot of poker and saw this hand go down the first time it was played on TV. I was sure Ivey would fold.

It's really hard to make a true analysis of the hand without more information. Is Ivey playing above his bankroll? Has he been losing recently? Does Booth have a backer? Did Booth have a side-bet that acted as a hedge?

This is obviously a truly amazing play on Booth's part. Ivey defines his hand when he plays it so straight-forward.

If Booth has a nut-flush draw, it's basically a coin flip. Booth could have the nuts, which would mean Ivey needs to draw perfect-perfect to a boat.

Really, the only thing Ivey beats here is a pure-bluff. Booth won his 50k, but undoubtedly that bluff, probably the biggest bluff in the history of poker up to that point, to be seen by so many people has paid off much more than that 50k pot.
DOM storage is cleared by default in the clear browser data menu in Firefox and (likely) Chrome. This is trivial to fix by making the iOS 'clear cookies' option also clear DOM storage, which I would assume Apple would eventually do.
If we remove the adjectives formed from proper nouns, turn the nouns into "people", turn the verbs into "bully", and add a pronoun and an adjective, we get

people whom other people bully bully people.

This makes sense.

But when we remove the pronoun and adjective and we get

people people bully bully people

which is as far I can tell gibberish (without changing meanings such that they don't correspond with the original sentence). It can't have anything to do with many people persons, because in the original there's an adjective there.

If we assume that, just as there are social adept people, whom we call "people people", there are also socially adept buffalo called "buffalo buffalo", we can get "Buffalo buffalo buffalo buffalo buffalo". But to go beyond that is to claim an incoherent sentence missing many words is coherent and grammatical.
The substance of that comment is that the xbox 360 has not been cracked open like the classic xbox.
I think philh already explained it pretty well. In your question you suppose the laser dot to be 'fairly large', which I think would complicate things (the shape of the dot 'smearing out' as it goes faster). For me, philh's explanation works best if you imagine the laser pointer to be a cannon of photons, emitting one photon after another at a very high rate and in a single direction, with the electrons of the moon's surface always reflecting the photons towards your eye (perhaps a bunch of strategically placed mirrors...).
I agree to some extent, however I have some doubts. Namely, Linux has a big developer base, however it's a bazaar: features into the kernel come and go, as support for hardware does. Grey suits do not like bazaars. Yes, Google has moved away from Microsoft, but that could be because they saw it as a competitor.

The Microsoft advantage is that they are business-oriented, and they provide the kind of support and services businesses expect: boring problems solved, backward compatibility, etc.

I stand on the Linux's side, but we'll see.
If you are a vimperator user you can do something similar with the InstaPaper plugin: http://code.google.com/p/vimperator-labs/issues/detail?id=11...

The thing I like best about vimperator is that it is a standard Firefox plugin. My understanding of Conkerer is that it is a standalone app.
It doesn't make any sense to define a gravity field by photons. They're massless, so they don't attract anything, and most of the photons a star has produced over its lifetime are speeding away across the universe billions of light years away from it.

Only things with mass can attract other objects with the gravitational force. Photons aren't in that category.

No, the sun disappearing would not be constant velocity or constant acceleration motion, so the info would indeed only propagate at the speed of light.

Justification implies hyphenation elsewhere. Personally, I think justified text is fugly without it.
What if you made it a bit more open?

Share some success stories on the site to give it some legitimacy too.

And why not create some MeetUp Groups in several cities with the people to network at local events with potential entrepreneurs? The co-founders would have to register on your site to attend the events.

I know you want to be selective, but if the net is wide enough, this could be huge.

(Disclosure: I'm seeking a technical co-founder myself)
Yep, I have a day job. Right now it takes very little time to run the site, maybe a few hours per week. But I definitely spent a lot of time building it up front, and occasionally still do when I add new features. As a strict hourly ROI I could have made way more at a job or doing consulting work, but it's an investment that may pay off long term (or not, but either way it was way more fun :)

It sounds HP's suit is based not on a non-compete agreement, but a provision of his $35M severance package in which he agreed not to disclose trade secrets or confidential info.

That's the impression I got from the article, anyway. I suppose it wouldn't be hard to argue that he can work for Oracle without disclosing HP trade secrets.

There is an interesting book by Adrian Slywotzky, The Art of Profitability, that goes over various profit models. I think the above example falls into 'Multi-Component' profit, in that the same product (water) is priced differently in different businesses (super market, convenience store, delivery); since customers behave differently in each purchasing situation you see the ability to price the product in various ways.

Another example would be how Coke is priced (to restaurants, grocery stores, vending machine).
That's surprising to me. The only place I see un-justified text is online. Books, magazines, newspapers, even the research papers I read all have justified text with hyphenation.
your post implies digg isn't a startup.
The startup is http://www.challengepost.com/ (the linked site uses their software/platform). This isn't the first government initiative to use their platform: http://www.readwriteweb.com/archives/us_government_taps_chal...

They really should fix the post title, I was confused and had to look it up.
Interesting. Do you have to be american to participate?
That might be the case... I mounted a heavy U-lock on the front forks of a mountain bike, made steering very heavy. Felt pretty similar to a heavy wheel to me.

Of course this is all subjective (my observation, and the parent's downhilling observation).

Definitely easier to steer lighter wheels regardless of speed.
Then shouldn't you learn from dating sites and go for the biggest network possible?
If you think about it, this explanation cannot be true. The main force the helicopter exerts on its surroundings is along the axis of rotation. If you tilt the axis of rotation significantly in any direction, the direction of the force will change significantly and the motion of the helicopter will also change significantly. Again, this does not happen.
It looked a lot like that scene from E.T.

More engagement of what in what?

I'd like to see less engagement of the government in everything. Why is the US Federal Government offering me twelve thousand dollars to come up with recipes? I hate to sound like one of those Ron Paul folks, but when did acting as a middleman for the procurement of recipes become a duty of the US Federal Government?
You _can_ turn this kind of scary "basement" code into something that's maintainable, but it's often a multiyear slog. I've salvaged C++ horrors that were virtually all basement code, intricate and fragile and dating back to Win16 code written in 1993.

Here's a recipe that may help you get started on your adventure:

1. Work incrementally. Never try to fix the whole program at once. Overhauling the whole program inevitably introduces lots of disruption for users and delays the addition of new features. This will not be appreciated.

2. Make sure you have tests. Lots and lots of tests. Any time you touch a module, write some tests for that module.

3. Build better module boundaries. This can be a mechanical process. For example, to separate disk I/O code out of a checkout register, declare a RegisterIO class. Every time the GUI code touches the disk, add a new method to the RegisterIO class and move the code there. You'll wind up with a _really_ ugly RegisterIO class containing a lot of ad hoc IO functions. But the RegisterIO class will improve with time.

4. Reimplement small modules one at a time. You may want to run the old and new versions of a module in parallel for a while (I once had a program with two different text rendering subsystems), or run the same unit tests against both the old the new module.

Eight years of work later, you'll have a reasonably shiny new program with some odd architectural decisions and a really ancient logging subsystem.:-) But at least you will have been shipping new versions and earning revenue every step of the way.
I really like this one too http://js1k.com/demo/12
Very, very bad idea. Speaking another language is unfortunately not about translating words but transforming language into another form while conveying the same ideas and respecting the author's initial wording as much as possible. Sometimes you cannot even translate without providing a piece of cultural explanation. Translating one word out of context is almost always bound to fail. This extension is useless at best, dangerous otherwise.

TeX justification really needs to be ported to browsers. Are those hyphenation algorithms really that hard to implement?
Unless Digg cannot roll out new features due to Cassandra (eg: a) Cassandra woes taking all dev team time, or b) tech limitations prevent features) it seems highly unlikely that cassandra is the reason why Digg 4 is grating with users initially.

It's a change of features/product rather than technology that is the problem.

Ask HN: How do we measure development productivity
I work for a company where 99% of our products are coded in our India office. We have many teams with different areas of expertise.

We have great developers, and the ones that aren't great often leave of their own accord because they don't have the necessary skill/aptitude to grasp our business and code base.

That being said, we have a difficult time measuring productivity. Jim Collins says we need to get the right people on the bus and the wrong people off (Good to Great). I feel like we've got the right people on the bus for the most part, but each coding task that we give is so different that we're struggling to use metrics to assess productivity.

We've discussed having project managers assign arbitrary point values to each task, but we worry some developers might just game that system. How have you overcome this (we have 70 developers and will probably have 100 by the end of the year).

It seems to me that there are two possibilities, and either way, Hurd should win:

1. It is possible for Hurd to work for Oracle without disclosing HP trade secrets. Then Hurd is not breaching his agreement by working for them.

2. It is not possible for Hurd to work for Oracle without disclosing HP trade secrets. Then the agreement is a de-facto non-compete agreement, and therefore unenforceable.
Show HN: Pocket Prospectus - White label iPhone app for universities/colleges
This started its life as a bespoke project, demo for a possible project. It turned out too expensive so I decided to turn it into a 'white label solution'. Making it easier and more cost effective for educational establishments to get their own iOS app.

It's core features allow customers to combine all of their existing feeds (youtube, flickr, picasa, twitter, rss news, etc) as well as custom data into an iPhone (for now) app for their current and prospective students to consume and share if they like.

The app can easily be 'skinned' to match the establishments branding guidelines and everything can be managed from a web control panel.

I know there are still changes to be done to the website, etc but I figure there's no harm in putting it up early.
