Celery is best on RabbitMQ, but supports tons of backing stores, not that you necessarily should[1].

How is RabbitMQ a lot of machinery? Compared to Redis, AMQP and Rabbit have the complexity of a bologna sandwich. It's actually a quite simple system, and very easy to install. There is almost always no configuration necessary. Developers can install it in one command with MacPorts or Homebrew or apt or yum and don't even have to create users or "vhosts" to get started. Create a named exchange, subscribe to it, you're now AMQPing. It's well-packaged and well-documented. It's also so light on it's feet that it rarely actually needs a dedicated box; just stick it on your database server to get started.

I think Resque is a good solution for Rails, for sure. I've built stuff around it, and it works well, and definitely battle tested. It certainly beats the existing AMQP-based solutions. The idea that your application code probably sucks and/or is in a constant state of flux, so handle failure gracefully is rather excellent. The web interface is particularly nice and useful. While I don't necessarily agree 100% with Redis as the backing store, the actual mechanics of the worker queue implementation (plus tools like resque-pool) work so well that for most projects, it's perfectly fine.

I actually had a problem specific to using Redis materialize when it ran out of memory while queueing a large batch of per-user-generated weekly emails. A cron job would spin up a script that would cache a large amount of database data in RAM, using it to generate per-user content. The rate at which email could be sent became a major bottleneck, and we had Resque, so we just enqueue'd the entire email and had a small job that connected to the email server and send them. This worked reasonably well and for many months, the high watermark for RAM usage was well below what the box could hold.

Unexpectedly, the amount of content contained within these emails quadrupled. Redis ate through all the RAM on the box and it started going to disk using Redis' VM mechanism. This was configured to "theoretically" prevent an unexpected OOM from making the queues unavailable. The unfortunate part is that the Resque stores the entire queue in a single key, and when the key gets swapped onto disk, Redis must read this entire key (and therefore the entire queue) into RAM before it's able to read any data from it.

This wasn't Resque's fault really. It was my fault. I did not take the time to understand how Resque and Redis worked well enough to make a truly informed decision. I did not test the OOM condition. I should have tried to fill up the queue on a test box with a billion items just to see what happened. All lessons learned.

Wait, so let me get this straight. The author goes into all this huplah in the beginning about "well these people could be right", but, towards the end he says this.... "The Kindle is going to be broken, sluggish, and unusable in the eyes of most tech-savvy users and developers, but I think it’ll sell well once Amazon plasters it across their site and will introduce a lot of people to post-PC devices."

I'm sorry but as an author you are horrid. Not only were you semi on the right track at the beginning, it actually made me read the rest of your article... then you said that. That "know it all, lets be completely hypocritical" type ordeal. How do you know what it will be. You are speculating the same as everyone else.

In other words, you article not only failed, it made you look like a hypocritical author just writing random thoughts down, then doing the same exact thing you were talking about others doing.

People are saying this is a game changer from a price to offerings ordeal. Game changing is more than just what tech it has, it's about price. This could possibly force I pads to come down in price. Is that not a game changer? People are so stuck on this well it can't do this, or that ordeal, when in reality, it's more about lowering the price of things. I guess your just one of those people that has to have a million apps and do whatver on a tablet (they are already worthless for any real computing), so it's more down to reading articles, tinkering here and there, a few games, movies etc. What is there to revolutionize asides from PRICE?

From tablets to Notebooks

1. First come tablets

2. Then tablets gets a stand (so you dont have to hold them all the time)

3. Then tablets gets a keyboard (so you can type quickly)

4. Then tablets gets a mouse like device (so you dont have to touch the screen while on the stand)

5. Then they run (your favorite distro of) linux

6. Then they become keyboard-less more portable laptops

7. Then we call them notebooks
Window's search feature, at least if you're on 7 and you let it index what you want to search, is perfectly fine.
Sadly, computers are cheaper with an OS. The vendors pile junk like 90 day virus subscriptions (that must be renewed) and Microsoft Office instant upgrades on to the computer as to lower the price.

I'd pick something off http://www.ubuntu.com/certification/ and be done with it.
Again, I agree that it's not one-dimensional. Tablets are making the consumption and light interaction aspects of computing accessible to a huge section of people for whom they were inaccessible before. And that's great. But the PC represented a tool that made the production aspect of computing accessible to a lot more people, too. And the web was a continuation of that trend.

Tablets look like the end of that side to me. It looks like an optimization of the consumption aspect at the expense of the creation aspect.

You may see it as a third device, but I think a lot of people see it as a replacement device, and those are exactly the people who could benefit most from tools that make it easier for them to produce things.

I think my ultimate lament was that the way the market works, of course large companies are going to privilege consumption, because they can make more money that way.

Letting Go Quotes
By letting go, we actually allow more of the mystery of life to come in for us - By Leslie Karen Lobell.
Could you elaborate on that? Do you mean apps? Or some other kind of content? I'm not quite following what you mean.
Not for me. Maybe it's a small region in the west coast. Who knows.
>but reading a novel on a backlit screen is no fun, and if it were, we'd read on our cell phones, because they're easier to carry around.

Speak for yourself! I do this and love it. I find that the faster page flipping more than makes up for the slightly less readable text. The thing that I think most phone/tablet makers get wrong at the start is not putting it in "night mode" by default. White text on a black background on a phone screen is so much more pleasant (at least for me) that it wouldn't surprise me if bad defaults are a large part of people's aversion to it.
Thanks for responding! Sounds like an interesting company. I wish more founders took this attitude.

I'm not gonna say I know your friend more than I do but what I can say is I understand why he says he is "profitable" even though he is not. Ok, lets look at it this way:-

"Looking deeper, turns out he's no longer pouring cash into the company, but unable to pay himself a salary."

Replace "company" with property and "salary" with capital gains.

Does it make sense now? He (and probably many others here too, including me) sees his startup as an investment and once an investment starts paying off by itself (break even), I will definitely declare it profitable and trumpeted it as a huge achievement. Why? Cause this investment is paying for itself and I can potentially sell it or earn more off it without bleeding any of my cash into it. Trust me, when you reach that position, you will be a very happy man.
@MostAwesomeDude I think you pointed out a major issue with social games in general, which is that across the industry, free-to-pay conversion rates are only about 2% and player only generate about $1 ARPU/month, meaning, to turn your game into a viable business, you need to have a ton of players or as you put it, "...you really want as many potential wallets as possible."

There are a few new monetization methods out there such as Kiip that you should check out, although I can't speak for how well they work.

One new monetization method that I can speak for, which is proven to work are, real-money gambling and betting mechanics, which produce monthly ARPU in the neighborhood of $300/month -- that's 300X better than the other monetization options currently available to game devs. I know the knee jerk reaction is to think you can't do that without a license and that obtaining a license is nearly impossible, both of which are true, but Betable (developers.betable.com) just launched a real-money gambling engine that hosts and operates all gambling code on behalf of a game dev, enabling them to piggy-back on Betable's licenses, so they don't have to get their own.

FULL DISCLOSURE, I'M THE FOUNDER OF BETABLE. Sorry for the self-promotions, but given the current state of game monetization methods available to devs, I thought it was important for me to jump into the conversation and make people aware of what else is out there. Hope this is helpful.

At least Apple, I think, sells music and videos and books and apps because people want them. Sure, they make some money (not much compared to the rest of the business) but they mostly do it to turn their devices into something people actually like to use.

People want music, want videos, want books, want apps. The market gives them what they want. This is not a case of the market delivering something consumers don’t actually like.

This is not a conspiracy of big companies to dumb people down. People are already that way. The PC didn’t help with that one bit and tablets certainly also won’t help.

Again: there is no problem.

See, this is super funny and all but (as much as hate her guts) I think this sort of think is playing into her hand, as Newsweek's editor Tina Brown found out from the backlash the cover caused. The way to handle such people is to show how hateful and inconsistent they are in a simple manner so the whole public can easily understand.
I'm not convinced that Amazon will be marketing it in the Kindle sector. Kindle at the moment is very much associated as a device incredibly well suited to reading a book, and the existing third generation one is incredible at this. If I'm paying three times as much for a Kindle tablet, they've got to be selling it me on features that compensate for the less-optimal reading screen and massively reduced battery life. They've got to be selling it on the basis of tablet-like apps.

This might mean a focus on magazine/more graphically designed newspapers, perhaps distributed through the Kindle Store, that take advantage of the nature of the Tablet's screen; but at the very least it will have to be a tablet with an exceptionally capable browser.

Thanks for the feedback. You are definitely right on #3 but we found going through the trials with our baseball teams that parents did want to share photos but none wanted to necessarily post them on any type of public service (such as facebook). That's why we did a quick and dirty implementation of them. Going forward I'd probably just like to offload that to a third party service and just provide a way for everyone to see the galleries for their teams from within teamloop.

One of the things that made Apple successful was having a very small number of products. Having a small number of amazing products is a good way to go.
I agree with the thrust of your argument. Many are drawing a false sense of opposition between consumption and creation. Listening to music (consuming) became insanely easy in the last decade, but, surprise surprise, the tools to create music improved just as dramatically. Just as importantly, the ease of consuming enabled musicians to draw on an unprecedented pool of influences - many genres have undergone wild transformations as artists have been able to access more inspiration with increased ease.

Some here might dismiss TV completely, but many consider this a "Golden Age" for television writing, too. Is it a stretch to think that almost unlimited access to the history of film might actually be inspiring more and more people to write smarter material for popular media?

I think the iPad is one vector. I think the social networks you mention are another. That also feels to me like a closing down, or a narrowing. I think Facebook, to take the biggest example, restricts and narrows and makes shallow our communication.[0] It reduces our interactions to shallow, superficial comments, likes, low-fidelity photos, etc. In its way, I think the move toward closed social networks is also a step backward from the open exchange of ideas that blogging represented. And I think this is partially due to the tools we've made, too.

This doesn't negate releasing an update of the e-ink Kindle; though I don't think this will necessarily happen.

I can definitely see another Kindle pricedrop on the cards for the Holiday season though.
No, as a matter of fact, I'm not yet. I plan on adding in something resembling a visibility timeout in SQS, before I do this. So that I can ensure that messages always get delivered. I was going to continue using SQS until this functionality is well tested.

Having said that, this is a good temporary solution for me to shutdown the crawlers. And I see absolutely no harm in abstracting the use of capped collections into an easy to use library.

Is it as well developed as a mature AMQP queueing solution? Of course not, I don't claim that it is. Having said that, I trust MongoDB in my stack as a means to communicate between processes, and am confident using it for the use-cases that I am. As long as I'm doing this, I see no harm in open-sourcing the helper libraries I create for doing so.

Am I a huge advocate of MongoDB? No, but if you happen to have it in your stack, as I do, It's handy to be able to use it in a similar manner to the way that Resque leverages Redis.

Hidden Benefits of a Bad-Ass Infosec Policy
If this device has no physical buttons, then it seems likely that it would have to be a true fork.
Two factors have led to the perception that tablets are "consumption" devices.

1) A tablet is a computer you can hold. Books and magazines have over time become optimized for holding (see size and weight) precisely due to the ergonomics of reading. Thus one would expect that tablets, which can store a vast number of books and magazines, would be "optimized" for such content.

2) Due to (1) it makes sense to trade power for battery life and thus iPad-era tablets use ARM processors. Word processors, music editors, video editors do exist for tablets and each has full privileges to have any interface it wants by assuming the full screen. Over time that software will get more powerful as these low-power processors advance. It can't be argued that iOS itself hinders content creation, but it can be argued that slow processors do. Time will take care of this.

Also I don't see consumption--by which you mean reading--to be a bad thing to do with a computer. Amazon's stated purpose for the Kindle is to enable every book in every language ever printed to be available in under a minute. That's an extraordinary vision if you think about it, and we're getting there very quickly. Hardly a step backwards.
Thanks! The one linked in the headline read like to chatbots randomly writing stuff at each other.
Nemerle is also a hybrid OO-FP, statically typed language, with subtyping-savvy type inference, targeting the CLI. Moreover, it allows metaprogramming using Lisp-style macros.

Nemerle has been available at least since 2005, but I can't blame you for not being aware of it. I probably wouldn't have heard about it, had I not attended the university where it was invented.

Check it out:

I think you mean "an insufficient amount of time." Some finite amount of time should be enough to come up with something quite good for any finite interface with reasonable requirements.

(And an infinite amount of time still probably wouldn't be enough to come up with a good interface based on bad requirements.)

Strangely, the pure spam doesn't seem to get turned dead very quickly, which is as you point out part of the difficulty with just changing the threshhold.

I'm just going to bookmark this comment, and someday I'll come back to it and have a chuckle about how short-sighted it is.

A good music recording studio costs more than many movie sets...and yet, people manage to make records that sell hundreds of thousands of copies with a few thousand bucks worth of gear. I've worked on records and movies and in television. I have complete confidence that great films and great television shows will be made by independent artists in the coming years.

Some early proof:

http://www.watchtheguild.com - Shot with Canon DSLR cameras, mostly in bedrooms.

http://www.drhorrible.com - Cost $200k to make, and included seriously high end talent, like NPH and Captain Mal. Netflix and Hulu could easily fund shows like this. Or, an independent production company could start turning out series along these lines. It takes far fewer viewers to pay back $200k than it takes to pay back a million an episode...and every eyeball that is watching Dr. Horrible is not watching Weeds or whatever content Starz has exclusive rights to.

Or, just browse WikiPedia: http://en.wikipedia.org/wiki/List_of_Web_television_series

A huge amount of money is not required to make something fun to watch, and the number of people who realize it will only increase with time.

I'm surprised someone on HN could be so short-sighted as to think that just because the old way of doing things can never be replicated on a tiny budget, it doesn't mean entertainment will not be produced in new ways on much smaller budgets. Doesn't matter how it's produced, or if it is up to the standards of high end movies. All that matters is that some people (even small numbers for any given film) tune into the new media rather than the old, and I'm certain some people will. I don't know anyone under the age of 30 that hasn't watched both the Guild and Dr. Horrible. That's what the future looks like, at least one aspect of it.

Python vs. Scala, a better breakdown
I can't speak for chc, but content creation on tablets and smart phones is real for joe average. Maybe not the kind of content joebadmo is thinking about, but the iphone 4 is the most popular camera on Flickr: photo and video editing power is given to the normal user without learning Photoshop or Avid. Even the customizing of your "personal" news magazine in apps like flipboard, Zite, ... is some kind of "content creation". Moreover, social media doesn't need keyboard and PC - most content on SM sites is created/shared "on the fly". I could go on. And lets wait for the integration of voice recognition in iOS 5 (and coming Android versions) - I don't thing the post-PC area is a step backwards. Content and content creation is changing for the non-power user ... and tablets and smart phones are heading to fill this niche.

Mom 'n' pop users don't care about "apps". They want books, email, web browsing, music, free streaming movies, and whatever silly game is popular at the moment (Angry Birds, Sudoku, and Bejeweled). A Kindle tablet can do all of these.
And here we find one of the major advantages of open source development: their efforts need not be lost, and that productivity need not be wasted. Instead, there is now an opportunity for someone to stand up and continue making MeeGo something awesome.
