Yeah, it definitely seems as though walking in to the businesses dressed nicely and giving an engaging demo has been a big part of our success. We plan to do some phone-only sales and see how those metrics compare, and then hopefully with the money we can get some people with actual sales experience (none of us have any background in sales). We're also planning on experimenting with some kind of referral system for advertising, where anyone can make a quick $100 if they can convince the local pizza shop to put up an advertisement. Of course, this opens up a whole slew of other issues, but it's something we're going to experiment with if phone sales proves ineffective.

And yeah, the 150-school roll-out is divided by region, they're all primarily west-coast schools, and we plan to launch at a large school and then follow with all the smaller schools in the surrounding areas, just because their markets will overlap and it'll make our work easier.
How are you currently finding ad deals at other schools? Have you thought about affiliate style sales? You promise a cut to affiliate members of those ads to the member that brings in the ads. Maybe too much overhead tracking all of that, though.
In their defense, why would they not do that? If the job description is already written up and looks good, why re-write it?
Not really that weird. Fast food is, by most metrics, far more popular than Michelin star restaurants. Doesn't mean it replaces them.
Someone help an Adobe-acolyte out: about how far behind/apart was Aperture from either Photoshop or Lightroom in feature set? My impression (from reading Wikipedia and past announcements) was that it was closer to Lightroom in intended use?

I've recently seen a few articles about startups/business ideas in the mobile/consumer photo space pointing at the problem of users not having enough storage space for photos. I guess? My perception and personal experience has been that users don't have enough ability to sort/filter the photos they already take. Digital/phone photography has allowed users to be voracious photographers...without a corresponding increase in being able to handle the information overload...it's already hard enough to pick the best photo among 5 - 10 takes, but a cognitive-chore to search through a flat-folder collection of thousands of photos with nothing more than a vague recollection of the photo's date...a wedding photographer once told me that by far, the best marketing tool he has is to produce a physical album of 50-100 photos, rather than just a PhotoDVD of thousands of photos. Theoretically, that DVD can be reproduced and sent around, and many more photos included for the client's enjoyment...but realistically, clients (and their relatives) don't find browsing through photo volumes on their OS default viewer to be engaging. Brevity in editing is important, but also, visitors to a client's living room can directly see and touch the physical photo album (and see who produced it), and that in itself is an effective marketing tool.

I guess this is a long way of saying that whatever the state of Aperture was, I hope Apple makes some innovations in photo sorting/filtering, rather than just trying to provide tools to beautify photos. I'd argue that Instagram's killer feature is how it limits the user's ability to hoard photos...once you take a photo, you are pushed into publishing it...the photo filter is a way to make you feel less self-conscious about it. After taking 100 photos with Instagram, you have 100 photos to show off in a nice web album. If you take 100 photos with just your standard phone camera app, you have 100 photos waiting to be uploaded/downloaded to iCloud into a standard file system.
If this were able to achieve any impact would it discourage longer term horizons?

I'm extremely excited for the Wayland support in 3.14. Being able to drag a window without it and the cursor getting out of sync really makes the interface feel that much better. It's equivalent to the difference in smoothness between Android and iOS.
I really hope thet will allow for (optional) manual control of where jpeg files are stored regarding the file system. The opaque "photo library" thing was really inflexible especially as the size eventually outgrows the internal SSD drives.
A copy of an email I sent to the designer, “A few notes about your Wikipedia redesign”:

> … custom formatting on some wikipedia pages might not look right. If you see anything like that, let me know.

The formatting of highlighted code examples is not right. Sometimes there is extra indentation at the beginning, and the syntax highlighting is always missing. For example, compare [your Ruby (programming language) – examples](http://wikipedia.moesalih.com/Ruby_%28programming_language%2...) to [Wikipedia’s Ruby (programming language) – examples](http://en.wikipedia.org/wiki/Ruby_%28programming_language%29...). Also, the code example `puts"Give me a number"` is missing a space compared to Wikipedia’s version.

There is too big a difference between the font sizes of normal text and of code blocks. In the site, code blocks are at a readable font size while main text is overly big, and when I zoom out to 80% to make the main text more comfortable, code block text is now too small. Picture captions and infoboxes also have this problem, to a lesser extent.

On [the about page](http://wikipedia.moesalih.com/?about), “email me” should be a link to “mailto:moe.salih@gmail.com”, so we don’t have to go to your personal website and find the link in the footer.
Care to say what are you dealing with instead? I hope it's not something obvious like "I build Obj-C apps"...
I think it depends on how the graph is represented. With the "standard" representations, it would be O(n) space in the worst case, where n is the number of nodes in the graph. You'd still only need the 2 pointers, but the traversal itself would need to also remember which paths it has not yet visited. The worst case is when the number of paths is much larger than the length of any particular path. The best case (apart from the null graph) is equivalent to the linked list, where there is only one path in the cover.

I can imagine representing the graph as a list of paths, in which case the tortoise-and-hare algorithm is O(1) space, though the graph itself would be (potentially much) larger. Virtually every other operation on such a graph would take a performance hit, too.

There may be other factors I haven't thought of, but you're right that the generalized algorithm could not be as space-efficient as the special algorithm.

It's worth noting, though, that the original question poised in the article did not place an O(1) restriction on space.
Does anyone know what their business model is? I assume one would pay for a subscription, but I couldn't see pricing information on their website.
A not quite serious solution [1]:

Let m = size_of_current_process / sizeof(list_node) + 3
Let np = pointer or reference to first node in list
while (np != null)
if (m-- == 0)
return HAS_CYCLE
np = np->next
return NO_CYCLE

[1] this approach might actually be acceptable in some circumstances
Great, now I feel like my reply was way too snarky. I'll give the XS IDE a try and I want to be clear to any Xamarin/dev folks reading here, I in no way think all this stuff should be free. I just see that as a limiting barrier and, judging by the comments here and elsewhere, so do others. I appreciate your reply and insight, thanks!
The 'debunking' was an alternate theory that didn't hold up to real scrutiny.

If the idea was a 'dark pool' to obfuscate their trades, not signal the market, spike the price, or avoid front running - then they failed spectacularly on every account.

the bots made up a large proportion of total value, they traded in a predictable pattern and were spotted quickly within days (and then taken advantage of by other traders), had unlimited buy demand which continued through a 2x+ increase in the btc price - defeating the purpose of spreading the order out.

it also doesn't explain why the bots trades continued while the API was down.

and finally, connecting to a dark pool should still show normal trading patterns, which the bot patterns were completely unlike (hence them being spotted).
When I worked in that area, the number we heard was Facebook got 3 or 4 flickrs worth of photos a month. I'm sure with Instagram the numbers are more impressive.
Right and as an independent dev Xamarin makes a mertic SHIT ton of sense, though once Ruby Motion has Android I'd argue that is a way better value. But as a guy working a day job hoping to bootstrap a startup/indie game on my nights and weekends $600-$2000 is ALOT of dough to drop, Ruby motion is $200 and I can swing that without much of a second thought, honestly I could swing $600-$2000 is within my range also I mean I'm extremely lucky in my salary compared to the rest of the world but it's A LOT harder to justify on top of a $3000 macbook pro retina, an intellij license, and the rest of my day used dev tools. Not trying to attack you on your stance I just would love Xamarin to rearrange their pricing to something that makes sense for different markets. I know that $20 a month plus 15-20% of app profits or something more flexible may make them much more popular with certain crowds.

Another thought-- Since there is all kinds of advice coming out of this which can be confusing / hard to parse, here is a slideshare on raising seed capital. It reflects what almost everyone is saying to focus on product.

If you need funds to help that happen, try an Indiegogo / Kickstarter / etc. This is a serious problem so it could see some interest

Have you gone back to the businesses you've sold to to see how much traffic or actual $ sales have been brought in by your service? If there is a measurable and verifiable ROI for them, you have a powerful lever moving into new markets. Those testimonials would be priceless.

What I would think about is recruiting commission-only sales persons in new markets rather than trying to go manage them yourselves. Likely, you'd use other college students. Start with another local school so you can jump in if necessary. Write up a 'how-to' guide with marketing materials for the prospects, and then look for self-starters who will go do the selling on commission only. Do some training. If they are empowered with testimonials from businesses who have seen a real return, they will find it as easy to sell as you did.

So the question is: can a single sales rep, likely a college student themselves, make enough money selling ads for you that it would be worth their while?

The goal is to get cash coming in without having to spend any to get it started.

The article is a little behind the curve, particularly with Google already releasing wearables.

Take what he says about Disneyland / Starbucks and apply it everywhere. That's what Google is already doing with Android. The wearable isn't the monitor, simply because 99.999999% of current wearable users will already have device with Google ID & location tracking (Google Maps).

(Curious how Maps tracking will play out on iOS...)

The big issue is that Django's ORM is built around traditional relational databases, while Google App Engine is not. You can certainly make the two work well enough together if you know what you're doing, but for someone just getting started, it's an unnecessary exercise in frustration.

If you want to use GAE, I recommend just starting with web.py or whatever is the default framework there. It's fairly easy to learn. If you need a place to host Django, a good chunk of the Django documentation is dedicated to discussing how to do that. There's also Heroku and what not as well.
Hi, I'm the author of Que. It's true that you can't really completely solve the idempotence problem for jobs that write to external web services (unless those web services provide ways for you to check whether you've already performed a write - see the guide to writing reliable jobs in the /docs directory), but that's a limitation that'll apply to any queuing system. I'd definitely say that Que, being transactional and backed by Postgres' durability guarantees, does give you better tooling for writing reliable jobs than a Redis-backed queue would in general.

I'm happy to answer any questions you or anyone else might have.
Well that helps clarify the question considerably.

To put it nicely, "So what?" (I know that sounds cruel but trust me it isn't) What you have is a bit of traction, you don't actually have a business yet and as such its probably too early for any but the most inexperienced of investors to invest in you.

You know you need more than the three of you, but lets focus on one school for the moment.

You need a "listings manager", a "sales person", a "student rep" for a school. Lets say your "unloaded" salary pool is $100,000/year (that is salary but not benefits cost[1]). You'll need revenue from advertising at that school to exceed $100,000 annually. Since you're just proving this out you three can presumably "play the role" of the three people you would hire here to do this. So you need a minimum of $8,500 per month in advertising revenue. You should target double that or $17,000.

Once you have one campus working, where it is paying more than enough for your three "campus specific employees" then you can start to think about investment to go further. An investor is going to ask you questions about "What does it cost per campus? what can you make per campus? What are the limits on that?" you will need to have really good answers to those questions which you don't currently have.

[1] This is a 'swag' or scientific-wild-assed-guess on an number, I based in a student working part time during the year getting about $10K/year (1000 hrs @$10/hr) A sales person being paid mostly on commission ($30K/year + 10% commission for $10K out of the advertising sales, and your listings manager making $50K a year straight up) You should adjust those numbers based on your own experience/insight

> You could keep some of these optimizations if Swift's message-passing mechanism preserved type information.

Type information isn't what makes this fast. What makes it fast is the very guarantee that dynamic dispatch breaks: knowing, for a certainty, where the function will land.

> As I mentioned, app extensions may be a step towards a more workable solution, but today, the ability to add PGP to mail using method swizzling is important to thousands of Mail.app users.

A fast Mail app is important to millions of Mail users.

If PGP is important then one interim possibility is to write your own mail client. That requires extra work, but one of the hallmarks of important problems is that we are willing to do extra work to solve them.
What I'm saying is, we don't have hard evidence pro or against Karpeles, what we have is a lot of speculation, typically made by angry people who lost part of their savings (or all of it in the case of Mr. Sillysaurus) in the MtGox collapse. That is not sufficient material to start a mob lynch.

The current investigation will hopefully surface whether the debacle was the result of genuine mistakes on the part of MtGox, or the result of wrongdoings. I'm personally reserving my judgment until we have more trustable information.
I still don't feel that Apple's next big move will be wearables. I think it's going to be something you can use in your living room, likely with games. Maybe iOS devices as game controllers.

Why is everyone so certain the iWatch is happening? Maybe I've been out of the loop but I haven't seen a confirmed, legitimate statement from Apple about it and I really don't see why Apple would release one. Watches aren't as common, the screen size leaves little utility and you've probably got your phone nearby anyways.

Happy to be totally wrong but I think a living room play makes more sense than a wrist play.
I completely agree, I had to go to Wikipedia to figure it out.
I have to imagine they'll do three things:

- Feature/Adjustments parity with Aperture

- Migration of 100% edits/metadata from Aperture/iPhoto

- Photos Extensions on Mac

The third will be really exciting. It's already going to be awesome to have VSCOcam connected to the Photos library without having to create duplicate images; this on Mac will be terrific as well.

I am looking forward to moving off Lightroom! Seems very far out for Apple though.
We speculate because its fun. But its not like we're pulling ideas out of the sky. Bits and pieces have been given to us, for example, iPhones now have fingerprint sensors. Its unlikely that all they'll ever do is unlock our phones. We also know of general problem spaces like mobile payments, or health/fitness tracking. Tim Cook himself said wearables are an interesting space and that he wears a Nike fuelband, thats pretty much a signal that they're working on a wrist device. We also know about their high profile hires of people who worked on health devices.

Ultimately, we entertain these assumptions because its fun and potentially profitable for us.
Raise slightly less than you need?
Years ago we had the choice of Aperture or Lightroom - we have been happy with that decision so far and this just confirms it. But lightroom still leaves a lot to be desired from a photo management perspective - and I wish there were more alternatives. I'm afraid that the one main competitor going away will cause improvements to languish in lightroom. Even though we didn't use Aperture, I will be sorry to see it go.
I am now wondering what to do if police officer will forcibly use my finger to unlock an iPhone 5S.
I think it just seems superficially attainable given things like 3-D printers and continuing improvements in AI, forget questions like how it fuels itself.
I'm not sure exactly what they're referring to, but they may mean that in a series of Monte Carlo simulations, the higher ranked team doesn't win every time, they win with a higher probability. Which means that (probably) more of the outcomes result in them winning, but (probably) not all of them. The article did say they were doing Monte Carlo simulations but I don't see where they're not, except for when they define the most likely bracket (in which case choosing the higher-ranked team every time is correct).
> Right now, it is so easy to use it for illegal activities, such as money laundering

Hmmm. Freudian slip?
I don't use Aperture, but I think it's really unfortunate that the standard practice for companies like Apple is to simply drop a product entirely rather than open-sourcing it.

Oh, absolutely, the business is incredibly cyclical--that's something we did a lot of research about before starting. The housing market is in full swing Apr/May/Jun, but students are still looking through September. Then it's going to die down a bit until December (though some will be coming in the middle of the year, or returning from study-abroad), and people start looking again as early as January.

We plan to use the downtime in our cycles to promote and brand ourselves through our blog and things like that. We want students to know about us before they even need to use us, and we're doing that by selling the "off-campus lifestyle" and glamorizing the idea of getting out of the dorms and living on your own.

If you want to pay yourselves even $50k/year you're going to need a few hundred grand. You could start with friends and family. But it does sound like some sort of accelerator might be a decent idea. Are there any in your vicinity (or in vicinities you would consider moving)? The accelerator would ideally help you with funding and pretty much every question you're asking.

If you do go the outside investor route, be careful with your pitch. Most startup investors are wary of near term cash flow & profits. That indicates a small return for them.
There's a critical difference in this case. If the lost bitcoins are now in the possession of some random hackers then Karpeles is incompetent. If they are in fact effectively in the possession of Karpeles then he is a competent thief. It's hard to tell but in the future they may catch him cashing some coins in to buy a yacht or pay the rent or some such at which point it would be distinguishable in a meaningful way. Being in Japan I guess he'd get away with it but in the US they'd be tapping his phones and so on.
You can already use your iPhone as a game controller, they have standardized frameworks available and 3rd party manufacturers like Logitech sell them.

However, that will never be a billion dollar market for them. It would be a supplementary feature for Apple TV, but would never be a big thing alone.

What school do you guys go to? I went to USD, and was surprised to see it listed as one of the 3 schools. Definitely think this is a great alternative to Craigslist, and the fact that the properties are pre-selected to accept college students saves a ton of time. And it's beautiful - good work. I don't have much advice on the raising money side, but as a user I love it.
The police investigation is mentioned twice in the interview, i.e. "The police are investigating the case so I won’t be able to say much."

There are various new articles about the Tokyo Metropolitan Police and Mt.gox "working together", but it sounds like you are right that the police are not investigating Karpeles.
