We actually do have a JS API [1] but we wanted to focus on a quick demo for developers rather than an integration wizard. I think it's important for people to understand the premise and how it's a bit different than other "analytics" products and just logging pageviews ala Google Analytics will give a sub-optimal experience.

We need to put a lot more work into the onboarding process (we created the whole public site and api docs and demo wizard over the weekend) so if you have any good examples of "getting started" flows that make sense, please send them my way.

Didn't they have more than 9 hours of outage?
This is pretty dumb and reflects the increasing mentality of "it's like X with the useful functionality removed".

Email is nothing like twitter at all, twitter became popular because it allowed celebrities and the like to share their thoughts with their fans without feeling like they had to maintain a longform blog.

Email is used for 2 way communication, yes companies like to build email lists and use it for push marketing but that's usually seen more as a nuisance to email users.

If somebody is going to charge me in order to send them an email the message I read into that is "My time is so much more valuable that if yours that if you want me to read what you say then you better make it worth my while".

And sometimes emails need to be long, am I supposed to maintain 2 separate email accounts?

In reality, legit commercial mass mail usually does have to pay to send because if you want good deliverability you are probably using mailchimp or a similar service.
New Book on Y Combinator: Author Talk in SF
Any network engineer i've ever worked with that's been worth his salt has had a system in place to backup his router configs before he does any update. The last place I worked at, we had a program setup to automatically tftp download the router configs at night and check them in to source control. We could then run diffs to see what changed if there was some kind of outage.
This is somewhat orthogonal but am I the only one that usually finds businesses built on "do X and help charity at the same time" as pretty weak? It's strikes me as though the business operator doesn't believe in the value they are providing so they piggyback off the value of donating to charity.

There are exceptions, things like the Humble Bundles, but I tend to buy those primarily as call to actions for charity donations themselves. Out of two bundles I've only ever played one game. I never got the sense of the value piggybacking (maybe determining how things get split is part of it).

I just get wary when charities are thrown into the mix with these things. It seems like something bolted on at the last minute to boost conversions.
"yet did not result in bringing other DNS services backup"

Can you be more specific?

Which other domain names did you try?

Also, I believe some parts of the world were unaffected by the outage.

I would guess a large majority of GoDaddy customers would not even know this outage occurred. They are "casual" domain name registrants and in some cases "casual" website operators. They registered some names and then never did anything with them. Or they operate a website but it's very low traffic and they rarely think about it. That is only a guess.

The problem is that it's difficult to know if a stranger might send you a long unsolicited email. Perhaps one of your friends meets somebody who might have a job for you and gives out your email address or whatever.

The majority of the spam I receive is under 500 chars anyway so it wouldn't really help in that regard.
In 2007 there were 8,324 deaths linked to MRSA in the UK. In 2005, there were between 4,429-8,850 (6,639 w/ 95% CI) deaths linked to MRSA in the US. There are more than 5 times as many people in the United States than in the UK.

I obviously do not have the specific stats at my fingertips to refute the anecdote you've supplied, but if there were a way for us to bet on which of our arguments the correct statistic is going to support, I'd bet on my argument.
Yes, it matters a lot how you die. For instance, there are 2,900 hippopotamus-related fatalities worldwide every year. Zero of those occur in the US. If you compare the US to Subsaharan Africa by hippo fatality, all you learn is that Subsaharan Africa has hippos.
I think this discussion has gone way off the main topic. OWS seems to be much more emotionally loaded than I had realized and I apologize for bringing this subject to the table. My point was simply that we have both more responsibility and more capacity for action than is evident at first sight.

I better leave it at that.

I think there are some good ones. I wrote this because I could get it running faster than I could get the data I've got adapted to existing ones. That doesn't mean they're bad as much as it means I don't understand the data I've got. :)

The way I like to think about document-oriented databases is that you store what you have when you have it, and worry about what it was later when you need to get things back out of it.

e.g. the big bag of stuff I mentioned in the blog post contains a few things I know I don't need, a few things I think I probably need, and a lot of stuff I just don't want to think about (I might need it later, maybe after some manipulation, etc...). Lob it all in.

The downside of a system like seriesly vs. a system like rrd (or any modern equivalent) is the same as the downside of any nosql database vs. a sql database. By planning up front, I can keep the size down and get more performance by incrementally computing stuff from the beginning. In the meantime, I'll just buy more disk. :)

I'm reasonably happy with the performance, though. There's a good number of visitors on the page right now and this is what they're seeing:

2012/09/11 12:28:50 Completed query processing in 82.54ms, 6,266 keys, 1,280 chunks

That means that for that query, it scanned through 6,266 keys in the on-disk b-tree, grouped them into 1,280 separate result "rows" to be reduced and did the necessary computation to emit all of them in under a tenth of a second while lots of other queries were in flight. My "extreme" cases right now are taking under 3 seconds on over half a million keys. I consider that acceptable for two weeks of side-project.
I thought about that, but doesn't it take away a bit of the simplicity? There's 2 more digits to process. And how much is a dollar today? And it takes up valuable space in the header.

I've struggled to answer this question. I guess I'll figure out if it's needed based on customers using the service.

Thanks for the feedback.

They don't really have enough bits here for asymmetric crypto.

How many bits are they able to reliably recover from the screenshot, especially if they want to survive simple downsampling? I would guess not more than 500, probably less than that given the patterns we're seeing.

You can't generate a ciphertext smaller than your key size. And 500 bits is really not enough to do typical asymmetric crypto safely.

A pleasing fantasy, but a fantasy nonetheless. The world runs on software these days. Everything around you has software in it, at every level: firmware, micro-code, operating system, drivers, server, client, network, etc. And the vast majority of it was written by mediocre programmers. There's simply too much production code in the world for it to be any other way.

Yes, mediocre programmers create mediocre code, and they have a harder time maintaining that code, but they still manage. Often times they have the advantage of money, resources, and people. With enough devs and a reasonable process it is possible to "polish a turd" into something that is functional and feature rich, even if it has a great many flaws.

This is the scary realization that most devs, including myself, have a hard time accepting. The software that your bank runs on? Yeah, that was written by hundreds of devs and if you interviewed each one you would probably only recommend hiring a tiny handful. The firmware your hard disk runs on? Same deal. Also your car's EFI module, your cable modem, your DVR, etc.

I don't really see how paying me would help though.

Either I want to read your email or I don't, paying me $1 a time to read all my viagra spam isn't going to help anyone.

How would a wizard know what MX to use or how many, their priorities, etc. in DNS? That's just one example. Email requires knowledgeable systems and operations staff. Many small to mid-sized companies do very well selling email services to others. You can purchase such a service, but even then, you or someone working for you has to understand MX records and DNS and why they are important, how to set them up, etc.

The motor braking is powered, not regenerative, so it can brake so hard as to throw you forward off the board! (Rode one of their early prototypes. Sheer awesomeness!!)
I this case it's more about the relative value of time for the recipient vs. the sender. It comes across as a little snotty to say "pay me if you want to talk to me." But charity still conveys the value discrepancy.
Hype aside, if Google & friends are making a marketing offering, it's just good sense to ensure that the details of what has been offered are very clear.

I am the author of Gow.

> This is a junk submission. Where to start?

I've never submitted Gow to Hacker News but it does seem to pop up every once and a while and it gets the project a few hits.

This is a project I work on in my free time (and I get paid very well hourly so it's expensive to me) and if it weren't for programmers like me you wouldn't be able to do half the things you can do on your computer, so unless you've spent thousands of hours coding for free then please stop spreading the hate.

> This project hasn't shown activity in 10 months.

Please do your research. I just made a big release yesterday so the user that posted this wasn't just spamming HN.

https://github.com/bmatzelle/gow/wiki/change_log

> Furthermore, the project is largely written in VBScript and batch files, which is insanity

I wrote that script 10 years ago and it works with every version of Windows from Windows 2000 on. I made Gow so I could use Unix utilities on all versions of Windows. If I wrote it in PowerShell then it would force all users to either use a new version of Windows or download the PowerShell installer for zero added benefit. The script just adds Gow\bin to the PATH. Gow certainly doesn't need PowerShell for that.
Ask HN: I know software. Now I want to know hardware. Where do I start?
I started with RoR 6 months ago and I can do cool stuff with that now (www.Meer.li for example).

I really want to go into hardware now, but I have no idea where to start.

Let's say I want to create a speaker system you can hook up to your iPhone - similar to this: http://www.kickstarter.com/projects/2107726947/hidden-radio-and-bluetooth-speaker?ref=live. Where would you start?
2KW sounds a hell of a lot, when a 250W motor on a bike can get up to 20mph? Do you actually use the full 2KW of power? it seems like it would throw the rider to me.

I'm willing to bet from ebike knowledge that the regenerative braking is more of a marketing feature, and may not even break even with the added weight. Have you done tests on this?

Others have touched upon price so i'll ask if you had any concerns about liabilities? and are you hoping to grow organically post-kickstarter, or a funding round?
Wow. Which leads one to ask, could you just take the motors off the board and put them on a bike? What's the new tech that makes these motors possible?
Ug. I'm going to defend them despite the easy ability to mock.

Each industry has it's jargon of puff words to convey complex things. In my field of physics, for example, we'll often use a short-hand word to cover a very complicated idea, with the understanding that everyone should know what your talking about... and if they don't they should go learn more about it. Entanglement, emergence, wavefunction.

The problem is when you don't actually understand the complexities of the idea just mimic (or make up) the language.

That said, "let's talk about disrupting the disruptors" is always eye-roll worthy.

Interesting fact: in Prague there are people offering sightseeing tours on Segways; it seems to be quite popular there.
Like I said, ymmv. I have no complaints.
You may feel safer on the sidewalk, but just like a bicycle, you may be safer on the street than the sidewalk. Most collisions happen in intersections. Cars do not expect vehicles to be crossing the street from the sidewalk at high speed, so don't check very well. Being closer to the center of the intersection makes you more visible, and ensures you're coming from an area where cars expect high speed objects to be coming from.

Being in Manhattan changes that somewhat. There are a large number of pedestrians there, so that helps with driver awareness.
The biggest problem with this idea is that it violates people's expectations. People already know how email works. They don't expect to hit a character limit. They will simply get annoyed.

If you want to "take features away", you need to create a completely separate concept in people's minds. Twitter works because people don't think of it as "email that's limited to 140 characters". They think of it as a completely separate category.
This is off-topic but I couldn't read the article past a few lines. The blurry background kept getting my eyes unfocused. Maybe it is time I see an eye dr.
And if it was human error, that's fine! Stuff happens and I can certainly say that I've done my share of human error.

I want to mention a couple things though. The first is that the blame is being placed (at least reading slightly into the PR release) on a 'technology' failure. That is fairly distinct from human error.

The other thing, is that if it was human error, how did the chain occur without a second pair of eyes or similar, such that the outage lasted more than a bit of time?

Third, why was the DNS changed to Verisign? That is still the biggest outstanding question I think in terms of their claimed outage reports. I should also mention that I do have skin in this game as plenty of customers were running at least SOMETHING through Godaddy and were yelling in this direction for stuff breaking...
Sure, and it does seem to be true: life expectancy in part tells you "this country has more cars than hippos". The car/hippo ratio is a very different concept than "quality and outcome of health care systems".

Thanks for the tip! Continuations, I know what those are.

Yes, part of what makes racket awesome is that it has a coherent design while fluidly integrating feedback. The challenge for me is to learn some aspect of it to the point where I can give constructive feedback. Sometimes I end up giving up before I get to that point. Perhaps the tower of concepts just has to be this high, and I need to just suck it up and give it more time/priority.
I don't agree that twitter popularity lies on how easy it is to publish on it but in the fact that it establishes a reading contract. I know exactly how much time reading a single tweet will take me so I can read them in many circumstances.
That's why I think apps like TwitLonger make no sense.

The point is not to remove a functionality but to further constrain a contract (and enforce it).
