Ah, I should have mentioned this in the post. The price is going to end up being basically the same. I could have done it even cheaper, but I'm paying extra for multi-AZ stuff (i.e., making the database and load balancer available in multiple availability zones, for failover protection).

Slightly worried. When GrubHub acquired campusfood.com, which had the best coverage in my area, they ended up losing almost all of the restaurants in my city. I called them up a couple times and GrubHub claimed that they would be coming soon, but in the end I assume the deals fell apart I was left with many fewer ordering choices.
interesting, i think i've been noticing this but wasn't sure what was going on. in my case it's more important to show each frame than to get a specific fast fps. guess i'll have to resort to frame grouping where i need the speed.
Aphyr, this is very lame, it's not common to see a work like what you did, and none of your stories hit the HN front page? I don't know what to think, but I hope that at least my post will help to show more people your awesome work.

Do you dislike global menus just because it reminds you of a Mac? Is it actually a bad thing, and why? Have you ever tried actually using Unity for more than a few days? I understand that old habits stay strong, but sometimes breaking out of them and learning a new interface can be beneficial.
Intel HTML5 Dev Platform
From Intel website:
If you've used appMobi's HTML5 development tools in the past, then you're already familiar with our new tools. We're introducing this set of cross-platform HTML5 tools as Intel's HTML5 Development Environment to help you more easily develop great HTML5 apps for all of your target devices.

If I understand you correctly, you want to have a type like

data Foo a = Bar a | Baz a | Qux a

and then also use a type like

data Foo' a = Bar a | Baz a

in certain places.

For one, this sounds like a perfect use case for OCaml's polymorphic variants[1]. I've always liked that particular feature. Honestly, most of the time, it seems like OCaml is the only language doing sub-typing correctly, especially in regards to type inference.

[1]: http://caml.inria.fr/pub/docs/manual-ocaml-4.00/manual006.ht...

Haskell does not have polymorphic variants, unfortunately. Happily, we can add them in as syntax sugar over multiparameter typeclasses[2]. The very first example in section 1.2 of this paper is particularly relevant here: they're showing how polymorphic variants make it easy to work with different kinds of ASTs. I don't think this is necessarily an immediately practical approach, but it's very interesting from a language design point of view.

[2]: http://guppy.eng.kagawa-u.ac.jp/~kagawa/PVH/PolymorphicVaria...

Your last example sounds like a prime case for using GADTs[3] (along with data kinds). You could write a type something like:

data Typed = Checked | Unchecked

data AST ∷ Typed → ★ where
Checked' ∷ Int → AST 'Checked
Unchecked' ∷ Int → AST 'Unchecked
Neutral ∷ Int → AST a

Now you can easily write functions expecting unchecked terms, checked terms or both. These functions will have type-checked pattern matching--you will only be able to match on cases for the appropriate type. The compiler can also do exhaustiveness checking based on the type. That is, if you write the following function:

checked ∷ AST 'Checked → Int
checked (Checked' i) = i

you will get a warning that you missed the Neutral pattern, but not the Unchecked' pattern. And if you do try to add the Unchecked' pattern, you will get a type error.

[3]: http://www.haskell.org/ghc/docs/6.6/html/users_guide/gadt.ht...

This approach gives you relatively little syntactic overhead at the use site--the appropriate type is chosen based on the constructors you used. You also get nice type-safe pattern matching. I think it's a very good tool for this job. Perhaps you should consider using Haskell more one of these days ;).
Switched from Rackspace to AWS - couldn't be happier. I think AMZN is really far ahead of the competition and their pricing seems to be as good if not better for many use cases.
What happened to Informix, BEA, SUN, ...? There is nothing special in the Yahoo acquisitions. Large companies buy marked-share, mind-share, users. The actual product or service often is of little interest to them.

Scribd looking for growth hackers and data scientists
Scribd (YC S'06) is looking for an engineer who loves data and is interested in being the first dedicated data scientist or growth hacker at a startup. We have a ton of traffic (top 100 website, 200M registered users), a huge dataset (over 100M user contributed documents), and a strong willingness to be experimental. It's basically a playground for growth hacking and data mining.

We have seen huge gains from growth hacking experiments we have done already, but we know there is a ton of low-hanging fruit optimization waiting to be unlocked. Some of the ideas we want to explore are: content classification algorithms, deriving quality scores from user interaction data, natural language processing for user queries, recommendation algorithms, and all kinds of funnel, UI and policy optimizations.

============

Who you are

You are an experienced developer with a strong business and product sense. You're highly analytical, can write complex SQL easily, and get a thrill out of watching metrics go up (we certainly do!). You can write both prototypes and production ready code, and have excellent technical judgement about when to do each.

You should have

* Solid development skills in some programming language

* Strong analytics skills, including high levels of comfort with databases

* Growth / data hacker's mindset

Other things you could bring to the table

* Data mining, machine learning, and / or NLP knowledge

* Knowledge of SEO and SEM

* eCommerce, online payments, and purchase funnels

* Web development skills

* Experience optimizing large-scale websites

============

Contact us

General info about Scribd is at http://www.scribd.com/jobs. We are building the world's online library and are in the SOMA area of San Francisco with a team of about 40 and a fun, startupy culture.

We're happy to talk more about the role. If you're interested, get in touch at jobs@scribd.com - this goes directly to us.

Why is it that brand new users are allowed to comment?
That's a poor analogy. The goal of a business is ultimately to make money. The goal of a family home is completely different.

You sell your business because you believe the exit represents some version of reaching your goal running the business (if your goal is to run the business, just don't sell it). I don't see any analogous reason to sell your family home (you might be forced to for financial reasons, but that's not why either of the mentioned start-ups sold, nor is such a sale likely to leave you with much money in the bank).
I think the majority of the anti-Yahoo bias is simply from the company still being alive, despite not having done anything right the last decade. A functioning market needs companies to fail quickly.
It's not time-consuming to eat healthy. So much of what you're talking about doesn't require you to be standing anywhere near the thing. Breadmakers for instance - flour does not cost you 3-4 hours to make bread, it costs you more like a minute to stick the things in the machine and press the button.

Pasta's about 20 minutes - which doesn't need you to be standing there. Bolognese sauce is about 20 minutes, regardless of the amount you make. Make a bunch of the things up and stick them in the freezer. - 4 minutes in the microwave, only a few seconds of which need you to be standing there.

Rice, similarly, doesn't need you to be standing there while it boils. Heck you can get rice-cooking machines. Anything made in a slow cooker pretty much by definition doesn't need you to be standing there....
If you think puppet/chef is too much complexity you might find saltstack worth some attention. I haven't used it in real anger yet, but I've really liked what I've seen so far. I see they've even got instructions specific to aws now too [1]

Also worth mentioning cloud formation as well [2]. That might make the pain of chef/puppet more of a worthwhile investment!

RDS is pretty expensive for what you get. You can't restore to a running instance from snapshots, you get very little control over the environment, and you can't replicate between geographic regions (only availability zones).

I know you said you're a two man shop, but in this case it may make more sense to leverage other IaaS DB services instead of RDS.
In a way, yes. I'm by no means poor, I have my own house (rented) and a couple hundred GBP of disposable income per month.

This is enough to live by and enough to keep myself entertained but it isn't enough to be able to save, it's not a viable income level to be able to risk my home and my safety on a job I could lose in two months time.

I checked out the Intel "HTML5 Dev Platform" and found it woefully lacking. It was, at best, an alpha product as I found it challenging to even get running. I'm not really sure what Intel is doing with this product when much better, infinitely more mature products already exist. I mean, Netbeans 7.3 offers far more functionality and the same "free" price tag. I was frankly shocked to see something so amateur come from Intel.

Cooperatives are common in rural America. One of my clients is an electrical cooperative that got started in 1939 as part of the Rural Electrification program. Grain elevators and similar agricultural infrastructure are very often cooperatives. Likewise in parts of the Midwest, telephone cooperatives are common - high bandwidth and low rates.

The flip side is that cooperatives are run like businesses. The electrical cooperative will cut a shareholder's power as quick or quicker than a for profit utility when the shareholder fails to pay their bill - I've been to my client's office on "Cut Off Tuesday."

If you do not load the any executable code from the network not. It should be Javascript Crypto in the browser does not work.

The problem is of course not specifiy to javascript. It should be "fat client crypto does not work".
They've specifically mentioned a few times being able to detect browser version and load the appropriate version of jQuery. The 2.0 branch is supposed to get cleaner, faster code by virtue of dropping old workarounds (I imagine in some instances this may be quite a difference, as they may be able to refactor entire code paths if they can make new assumptions).

As such, they need to keep the API standard between versions. Unfortunately, they don't appear to have settled on the best API yet, so are constantly working to improve it.

I doubt the functions you are seeing removed[1] from 1.9 are specific to 1.9 being special or dual released with 2.0. They were more likely just removed because they were at the end of their deprecation cycle.

Ask HN: what are simple problems where Machine Learning can help?
I've been doing a lot of machine learning lately, applying models to do classification and regression. I'm trying to find simple problems that people have where machine learning could help. I would love to have a discussion about it.
I think if trying to explain things like these to programmers, maybe you should consider using actual code (or even pseudo code) for this? It would have an added benefit of not requiring to know math-english (for non-native english speakers like me) or any advanced concepts of math at all.
Yep, recognizing the problem and addressing it can be more important than the particular form of the first step you take. Every kid is different.
Biggest pain points

-contracts. customers hate them but they seem like a must have. For example I sold my old company to terminix. I would go from 5 million to nothing if they weren't contracted customers.

-the customer service experience hasn't really changed in 20 years. I am even guilty of this. It's just the same crap.

-customers expect to see ZERO pests, which is impossible at this point.

I just spent the last year losing 60 pounds. I did so by reducing my food intake. At one point I began to exercise without reducing intake and I began to lose weight. Once classes started, I could not longer exercise as much and my weight loss stagnated. So I tried simply eating less and continued to lose weight. I lost about 40 by exercising only and about 20 reducing intake only.

There is a difference between protein calories and carbohydrate calories and how each is processed, but beside that, calories represent energy. Energy that must be used. Otherwise, it will be stored.
I don't understand what you mean with the CLI aspect of acme. Could you elaborate?

Can you share approximately how long the process took you? Thinking of going down that road with 2 small basic heroku rails apps 1 web, 1 worker, 1 small postgres DB. very little traffic. Both apps already at ~$170/month on Heroku. These are paid SaaS B2B apps, but they generate so little traffic but the way heroku partitions their services or addons, this really should cost like $30-40/month on a regular "hosting environment"

I know almost nothing from a unix sysadmin perspective, but would invest the time if it is feasible.
Westboro Baptist Defector Struggles With Her Past
From the OP:

> I changed the app to use cookie-based sessions, so that session data is stored in signed cookies rather than in memcache. This way, the web app servers don't need to share any state (other than the database). Plus it's faster for end users because the app doesn't have to hit memcache for session data.

The switch to using cookies for storing session data instead of memcache has tradeoffs. Sure, you no longer need to ask memcache for the session data. But you are also shipping a significantly larger cookie back and forth on every request.

If you're storing a lot of data in your session, this could actually slow things down in the long run. [1]

Europe is populated far more densely than the US and there is plenty of competition in individual markets (e.g. Germany), so I doubt that this will slow down competition.

What I really hope it will achieve is abolishment of roaming in any particular form – I have a German contract with German O2, currently stay in the UK and am usually logged in(?) to O2 UK’s network. Yet this is ‘roaming’ and forces me to pay more for calls, while paying less for texts (€0.1 per text by EU regulation rather than unregulated €0.19 at home).
Yep, FLP applies here--but if a network works long enough to complete a round eventually, e3PC or similar can succeed. Pretty much all real-world networks do that. :)
My one talk with Marissa Mayer
"Staircase wit": http://mathpages.com/rr/s1-07/1-07.htm

Taking a close look at Einstein's work (which that book as a whole does a great job of) shows that certainly, Einstein was surrounded by the tools necessary to do the job (Lorentz, Reimann, Minkowski), some dating back decades... and yet, he is the one who actually used them correctly. It obviously was not an "obvious" synthesis, and in the end I do not think we can come to any other conclusion than that Einstein still did something genuinely important and interesting. It simply wasn't in the vacuum that the popular understanding has it to be, but that's hardly surprising.

There are some hedge funds that invest in startups, along with the investment arm of other companies (Microsoft bought 1.6% of Facebook pre-IPO), but I don't know if it'll work for mutual funds. Hedge funds and companies can sit on a startup for years before getting any return, but mutual funds have to be much more liquid. It could work as a closed-end fund, but those are much less common than open-ended funds and you lose the ability to reinvest in the startups.

This sounds pretty great. I haven't used Heroku, but have used Rackspace, AWS and Linode.

What worries me the most with AWS, is that there's virtually no support. I guess you can pay and get decent support, but on the low-end of the scale, it's pretty thin or non-existent. Now, I don't hear of so many issues with AWS that warrant contacting support about, and I don't face any issues myself, but just the thought of something going strange and having nobody to talk to makes me nervous.

In contrast, Linode does not have so many cool features, but their support is there and very responsive.
I'm a PHP dev working with Apache on a daily basis, but besides .htaccess and some minor changes I can't really do much. I would love an article which explained in a simple way how to scale your server and really debug problems with it.

Right, but it's hard to tell what are just inherently bad decisions and what are bad decisions given the context and company culture. Some of Johnson's bad decisions were because they didn't gel with JCPenney's culture...however, to my point, it's possible that Johnson's choices could've worked great if the JCPenney's culture were more flexible.

Yes, it's the CEO's job to make decisions based on what she has at hand and what she knows of the ship she's steering. But I think this underscores the point that the nature of the ship is as important to the CEO's initaitives as the quality of the initiatives themselves.

So to say, "let's ignore that Yahoo (in the opinion of some) has been a creaky, slow-moving ship for the last 10 years and see it as an entirely new ship now that it has a new CEO" simplifies the situation a little too much.

I'm struggling to find anywhere in the cited Ubuntu blog post that talks about a vow to maintain focus. The summary itself never revisits that phrase to explain it further, and while the words "maintain" and "focus" do appear in the Ubuntu post, they are completely separate and there is no theme of vowing anything or staying focused on any particular thing. If anything, it's the opposite.
