I also used to work for Erik's (dinkytown location).

That was the gross margin on bikes, which I'm pretty sure means (sale price - purchase price)/(purchase price). Correct me if I'm wrong about the formula.

Not included in this is 36% number is the shops cost in selling the bike, which includes,

* Assembling the bike (unpacking, assembling, getting rid of packing materials, which are substantial).

* Tuning and Selling the bike.

* Post sale service.

At least for Erik's, a big part of the post sale service was to get people back into the shop and try to sell them accessories. I don't mean un-necessary parts or work, but things like clothes, bike computers, etc..

For many shops I suspect there is not much profit per bike left after these other expenses.

Erik's stream-lined much of this process, for example most bikes were assembled at the central warehouse by a dedicated crew.

You could add a clause that states that your software can't be used for certain purposes. That might not stop its use in some cases, but large corporations that supply the military would likely think twice.

That said, in (almost) whatever country you're in, there are people out there putting their lives at risk to defend your freedom. Sometimes they probably end up bullying people for no good reason (perhaps even over the course of years) and engaging in self-sacrificial operations, but that's not their _only_ function.
First Django succeeded. i.e. Instagram and Pinterest. Second you guys have Sinatra. Quite often when I inspect a webpage of a notable site, I find Backbone in the mix. Agree or Disagree?
As simple as the graphics are, I'd wonder whether it couldn't have been done another way. You're definitely right, not targeting 2.3+ is kind of a big deal.

The game is very decent, though; runs very well on the Nexus 7, solid gameplay, nice mechanics.

Disproving common misconceptions of penny auctions
I wish I could upvote you more than once for this.

It also doesn't matter if something in life derails you from the game for a few years. I have the situation where the first several years of the life of my special needs child required a different approach to things. Am I any worse at doing startups than 5 years ago. Hell know, I am more experienced than ever. I've done startups for over a decade. I have had some real successes. No home runs (the one exit I got was small 7 figures and the acquirer tanked shortly afterwards), but I can show a track record of knowing what I'm doing.

But I'm now 41.

Given that the route to startup success now seems to go through angels, unless you are a superstar who can go straight to a big Series A with a VC. Many angels - not all - are young and made their money being in early in someone else's startup. Their comfort leve is investing in younger and less experienced people.

VCs themselves are looking to find Zuckerberg cos they missed him first time around.

No point complaining. It's the reality I live in. Just means I have to bootstrap longer and find revenues earlier. I am hoping this just means I build a stronger company. Getting funding to grow is never easy. It's not supposed to be, but the system is broken when it completely discounts experience in favor of youth and an ability of strings enabling you to work 100-hour weeks living on Ramen.
I guessed microsoft correctly (because of the flatness) but the rest I had no clue.
$40/hr is a pretty ridiculous salary for an intern, good for you, man. Maybe you, personally, were worth that much, but on average, it's at least double of what the companies should be paying to interns. Heck, $15/hr should be fine.
Less cynicism on HN might be a good thing, too.

While this looks kind of interesting, I've seen a large number of things that fall into this vein, and a few concepts seem to be missing (conflict resolution being a big one). Independent of that, though, when I first started working on my book, there were two tools I quickly needed but could not find. The first being a way to save references that linked outside of the document without being part of the document (think fact checking, reference materials, etc.). The second was a way to edit the document(s) and be able to compose sections/components together at a high level. I ended up using muse mode for emacs and fossil as an VCS (the wiki is particularly helpful for collecting resources). What I ended up doing is several files on different topics, then one for each chapter and then one for the book as a whole. Then it's versioned text copy and pasted between files. If anyone has a better system for linking to references and managing the structure of the book, I'd love to hear it.
I think as the other reply you got to this states. It's not slamming VC culture. It's recognizing a reality. And your point actually reinforces it.

Jody Sherman - who committed suicide after all - was under the increased pressure of knowing if he doesn't make THIS one a hit, he probably won't be given another chance. That is part of the whole stress, and the problems related to it, that are in question in this thread.
Eyeballing it:

- $300 for the steel frame (retail cromo disc-compatible frames are in the 400-500 range)

- $200 for cheap disc wheels

- $100 for the disc brakes

- $200 for the remaining components (levers, crank, seatpost, saddle, etc)

So yes, $800 seems perfect. I couldn't hope to build a bike that cheap at retail cost.
Not enough detail here, but I'm surprised when I see the terms "voice" and "TCP" together. Do they use TCP to set up the call, then UDP to handle the audio?

Edit: Yep, they use UDP for the audio: https://github.com/WhisperSystems/RedPhone/wiki/Signaling-Pr...

It was originally supposed to support 2.3+, but due to timeline constraints I had to release it as 4.0+. I'll be looking into 2.3+ for a future release though!
When Online House Hunting Heats Up
It does feel large in the hand, but fits reasonably in pocket.
Nit-picking: Wars are not waged to prevent genocide. Countries are left alone to kill their own people, and afterward we may punish the perpetrators, but no action is ever taken before or during a genocide. Also, waging a war for independence is typically called an "insurgency" or "terrorism", sometimes with a more heroic title such as "revolution" or "uprising".

What's not subjective is that war is (almost) always fought for the wrong reasons. As far as ethics, "Just War" is pretty ridiculous; that the highest officials in power think it's a good idea to murder people, but only in specific ways, is just a joke.
Unfortunately, double blind studies of acupuncture are impossible (the person doing it must know if they're putting needles in), and single blind studies are almost impossible (the patient can feel the needles, and tell how far in they are). The only thing than can be tested is the traditional Chinese medicine chi flow idea, and even assuming there's no chi flow along meridians, that doesn't mean the special locations it tries to explain aren't valid for some other reason. But it can't be tested.

It's all deeply frustrating. I tried acupuncture a few years ago (at a doctor's recommendation) and did a lot of reading. It didn't work for me, unsurprisingly - about the only thing it's been shown to have any effect for is some types of lower back pain, and my pain was (is) mostly in my hands.
That's coming from Google, who makes money off page views. Amazon has a different model, so I could believe the latency sensitivity of its business is different.
Oh, I see. Thank you.

After asking around on IRC, I found out about CEAN, which looks like it's trying to be a central clearing house. But it's a little strange looking compared to ones that I'm used to... it doesn't look very community-oriented. I couldn't even find a license file for CEAN itself.

But it looks like rebar offers a lot already, so I'll look into that more.
Yeah, this will be interesting. I've also been going through Learn You A Haskell, making an Anki deck as I go. Slow work, but Anki will help me retain everything I'm learning.

CommonJS is a very good example of what I was talking about. It's nothing more than a hack to work around JavaScript lacking proper language-level support for namespaces and modularity.
Sorry, but what did you expect? I thought the search engine was great, but search engines like that only survive as long as they are "underground" and not too many people know about them...at least not too many regular people. Putting it here to show up on the front page of HN pretty much guaranteed it will be dead soon one way or another. Because then MPAA & friends could also use it to send mass-takedown requests to Mega. And they have to comply. So to protect the users, they chose the next best thing - denying search engine indexing.

Thanks to its encryption, Mega can only be used (safely) like Dropbox and F2F sharing. Anything more public than that, like say Mediafire/Rapidshare stuff, gets them to square one, where nothing is safe from MPAA/RIAA, and can be easily taken down by DCMA requests.
After processing the full article, I'm completely amazed at all the extreme lengths Chrome goes employs to speed page loading. From the networking stack, with it's abundance of optimisations and resource reuse, to the massive (and slightly scary) intelligence of the predictions stack, it all combines to make one heck of a browser!

Even if Chrome had only 10% of its current features, I appreciate the fact that it provided competition into the browser market and spurred innovation by _everyone_. The benefit to the internet community as a whole is tremendous.
I agree 100%... but doing so would not protect you from the security issue being discussed.
I think this might be exactly what I need for working with the freelance writers that I hire. I'm looking forward to giving it a try!

Wow, very nice. Really shows how minimalist design can let you use the framework without resorting to OpenGL and still look great.
Sounds like a herniated disc in your neck. Given the time frame it seems stable -- but the only way to fix it is probably years of difficult physiotherapy or surgery (and then physiotherapy).
There is no "speculation" here:

When you measure latency, you always have to be careful about clock issues at the point where you measure the start and the point where you measure the end. This is old-hat for sysadmins and others who deal with these types of issues. This is why round-trip latency numbers are easier to work with: both the start and the end times are taken on the same clock.

It's clear, given nanex's responses, that they depended on someone else to give the timestamps. Before concluding that someone had inside information ahead of time, they should check their processes. It's like someone claiming they built a perpetual energy machine because they confused power with energy (i want to say it was paul newman but the name escapes me -- this actually happened)
It seems like an indicator of the current progress of the stage.
Are you 6 years old, autistic or female?
Actually, filing duplicates is a good thing. They will get tracked and appropriately linked together. Not only will the number of duplicates act as a proxy for "votes" for an issue, but the varying descriptions in the duplicates may be useful for engineering to properly diagnose the issue.
>cocaines current production cycle involves people who work for little money to avoid being killed in the fields.

Legalization of coca agriculture in Bolivia has significantly reduced this. Part of Evo Morales' nationalist/socialist platform is the renormalization of coca production and consumption. So individual coca farmers now grow their product in the open, without fear of persecution from the police. This means they don't rely on the cartels bribing police for their protection.

Life in Bolivia isn't exactly peachy for most of its people, but it's certainly better for its coca farmers than it used to be.

A nuclear tipped rocket is indeed not a great example.

On the other hand, say you had someone with a passion for rocketry and space, who found that the best way to pursue their dreams at the time was to build conventional bomb tipped rockets with slave labor...

With the traditional VoIP stacks, yes. There are two components to making phone calls: messaging and media. The messaging part sets up and tears down calls. The media part passes the audio.

I'd imagine they're doing the same.
They'll still be traded over the counter elsewhere at high frequency, so I think the end result would be widening spreads on the new exchange to cover the variation over a time tick (whatever length that is), and no one (even long term investors) would actually use the new exchange.
My theory when I started seeing a spinal surgeon was a herniated disc at the C8 root. But an MRI ( http://demoseen.com/mri/ if you'd like to see the imagery) didn't show anything of the sort. At this point, it's looking likely to be either Thoracic Outlet Syndrome or another injury to the nerves there.
IRC is great and relaying on such a simple and well understood process is smart. It provides group chat, persistency, and is much clearer than trying to decipher a dozen people talking on a radio frequency.
1800 / bedroom? That'd be an amazing deal in SF.
That looks like a hardware product. You still need to purchase market data access to the relevant exchanges to get that data, and those are expensive (NASDAQ costs, for example, run upwards of 20K/mo to get the lowest-latency data)

They should just spring for the data before making accusations -- the problem is that when you cry wolf all the time no one will take them seriously when a real case comes around.
Using very naïve calculations, it looks like they lost up to $5 million in revenue because of this.

> I'm not sure that means anything. In an OO language, you are always de-serializing into objects, and objects are always 'executable code'. Hashes and Arrays are executable code too, right?

No. You're conflating code and state (which was the problem to begin with!)

Let's disassemble parsing a list of strings:

When you instantiate the individual string objects, you do not 'eval' the data to allow it to direct which string class should be instantiated. You also do not 'eval' the data to determine which fields to set on the string class.

You instantiate a known String type, and you feed it the string representation as an array of non-executable bytes using a method you specified when writing your code -- NOT a method the data specifies.

The data is not executable. It's an array of untrusted bytes. The string code is executable, and it operates on state: the data.

You repeat this process, feeding the string objects into the list object. At no point do you ask the data what class or code you should run to represent it. Your parsing code dictates what classes to instantiate, and the data is interpreted according to those fixed rules, and your data is never executed.

It should never be possible for data to direct the instantiation of types. The relationship must always occur in the opposite direction, whereby known types dictate how to interpret data.

> I think it was not obvious to a bunch of people who are in retrospect _claiming_ it was obvious to.

Given the preponderance of prior art, this seems unlikely.
HTML5 'turns web pages into computers': Berners-Lee
i'm confused (which is not too surprising as i am no expert on this). why can't they hole-punch through nats? then they would avoid the extra bounce-through-server latency and would hugely reduce the load on servers. i thought that was how skype worked, for example.

(i realise this doesn't stop their "fastest first" idea being useful - i got kind of sidetracked by the explanation of how servers are used near the start of the post).

[ah, ok. thanks for the explanation.]
Less than 1% of companies get VC funding, so getting funded makes you more than 24x more likely to get acquired.

I wish the report had more bayesian probabilities to account for survivor-bias.
It was actually someone from Amazon themselves, reporting on a/b testing they did, that gave us the numbers of 100ms of latency cost them 1% in sales. People might wait for Amazon to come back, but if it's slow to navigate back and forth to compare brands, or slow to return search results, or slow to just render the page, you can easily imagine losing some percentage of people or just some percentage of what you could have sold to them.

For the most part HFT just decreases or eliminates arbitrage opportunities, or price discrepancies between what a piece of information says the price will be and what the price currently is.
Arbitrage has always been a 'feature' of the market and although there are increased barriers to entry for arbitrage, economic theory says that by eliminating arbitrage opportunities through trading the difference away the market is being made more efficient
Command-line AirPlay video client for AppleTV
> The Pro version is what I think a lot of people are waiting for

Yes, and "waiting" is the operative word. I think in the end the split release has been a big problem for Microsoft. So many people have held off buying an RT tablet simply because they want to "see" a pro version before purchasing. Even if what they actually would buy is RT, they still wait just to be sure. And now the hype is gone and the momentum is dead, a slew of new and better spec'd products is arriving - and a big window of opportunity is gone.
I went the other way, started using ruby and then switched to python because of the machine learning libraries and async frameworks. I found rails too bloated and too much magic and fell in love with minimal frameworks like tornado that i have a lot more control over. My productivity increased dramatically using tornado and flask. It seems like each of these languages have their phases to be on top, right now i am using nodejs and twitter storm for a project and i am finding it quicker to build async web services and the amount of async libraries is really helpful.

Scala is allowing access to some good java machine learning libraries and tools such as mahout, scalding, storm, akka, finagle, therefore i believe as a developer we should not define ourselves to a platform or language but we should always be curious and use the best tool for the job. I am not using tornado for my current project because nodejs had the async libraries i needed, that simple.

As business opportunities are arsing around big data, sensors and the internet of things our favourite platforms and languages are going to evolve as well.
I moved city a few months ago while still working for the same company. Prior to moving I was a remote worker doing software development and client support from my apartment.

It was a great set up for me - if I wasn't feeling productive at 9am I could defer until later when I was in the zone. I tended to work at night when my brain was buzzing, and got much more work done compared to now.

Post move, I am now required to work 9-5 at a desk in the company office. I honestly feel like my productivity has plummeted. Work loves having me there because I can play a more senior role to the more junior/less skilled developers, but my pay hasn't changed and I don't really feel like I benefit from it.

Perhaps I was just blessed for too long, and need to get used to what working as a developer in this day and age is actually like for the majority.
Indeed, it's a progress bar.
