Take these kind of comments to Reddit, you obviously know nothing about Rails and Ruby, especially Rack and Metal.
"Metal components operate outside the realm of the usual Rails timing and logging components, so you don’t get any internal measurements of page performance."
The secret to burning a lot of calories is resistance. Try arobic weightlifing for a while. You can get a resonable caculation of work by mesuring the the energy it takes to move the weights * the inificency of the human body.

PS: I don't know if this is a good idea, but I used to peg my heart rait at 190-200BPM for 45min to an hour a day.
Being too successful is a funny way of describing premature optimization and the risks behind great yet narrow specialization.

Specialists are by definition exceptionally successful in exceptional circumstances. I don't think that makes them too successful. It just makes them high risk-high reward takers.
It was there when this news.yc item had 0 comments. Also notice in the flickr comments the answer was given 6 weeks ago.
'day jobs and their stupid managers' This says a lot about your maturity and attitude dude. Your manager is your manager for a reason, one day you'll work it out, I'm not going to help turn the bulb on, you'll find the switch one day. I also note, it's normally people in 'day jobs' that has as negative an attitude in life as you. We're offering the chance to join our dream not to work as a slave!
Yeah, obviously. The OP's point is that attributing the drop in CPU usage to PHP5 (which was the answer to the original Flickr poster's question) is non-obvious (or it is a plausible candidate among a bunch of possibilities).
This is a good article, and the consensus among food writers, reporters, scholars and enthusiasts is clearly that much of western food/agri regulation is wrongheaded (note that even "enlightened" continental Europe retains some of the US's signature bonehead moves, like bans on young raw milk cheese).

That fact does not, however, indict the whole concept of regulation. Nobody is making a case for why yard sales should sell recalled or contaminated toys.
True, but you could also look at it this way: perhaps these 37signals articles are helping to illuminate WHY some of these things survive.

After all, success criteria in iPhone apps (or apps in general) may not be objectively quantifiable, but I'm sure there are plenty of do's and don'ts that will help.
That was very thorough, thank you. I wish people thought more about the context within which the chose to apply words.

Shall I put out a request asking for someone with very little experience and no previous proven application of that knowledge and skill? Then maybe you will apply.

It's actually not that bad. I updated my little game "Recall" coughshameless plugcough and it only took a few days from submitting the new binary to getting it pushed through.
This is less an interesting comment than it is a My Chemical Romance song. I also note that you've ignored a few of the other powers governments have, like deciding how much fat a steak needs to have before it can be called "Prime", or generating statistics on the number of businesses operating in 2003 with 50-99 employees.
No, it's nothing like Swoopo, it's not in that space at all. It's also 'like' a reverse auction but it's not. It's not in medical or in military but it is a very big industry. It's actually targeted towards construction initially. But it's NOT in construction.
I've been running Rails 2.3 in production for a while with great performance.

In the article the author mentions it has to do with serving static files, which is something that nobody should be using Rails to do anyway. I'm not surprised nobody found it until now.
Online Marketing Does Really Help Sell your Unwanted Timeshares
Most of Timeshare owners tend to hire or seek the services of an online sale-by-owner marketing or advertising firm. With these companies or marketing gurus, your overall agenda in doing this covers the following:
• To be able to market your Timeshares throughout the web to cover a broader audience. In terms of millions of traffic or surfers that may bump to your ad and be interested with your Timeshare.
• Doing this approach may simply cut-off marketing expenses compared to advertising your ad on TV or radio. Online marketing has a competitively low price in terms of advertising or marketing your Timeshare that has been for sale in decades.
• Online advertising or marketing assures you that you deal with “straight talk” and there are no hidden fees from online advertising or marketing firms.
• The bottom line here is that due to the various marketing and advertising schemes that you have implemented, none of those have succeeded and this is the last “straw” to get rid of your timeshare and this now depends on the online marketing or advertising firm or company that you are scouting for to do this.

How to Track an Online Company that Can Help Sell your Timeshare?

That is the most important question of all and there are various online firms that promises that “they can market your timeshare property to thousands and thousands of traffic or surfers on a daily basis”, organic traffic or “real persons” who will be interested in your timeshare inventory and that these companies are actively mining the net to track these investors.

But even if there is a slim chance to get that perfect company or firm that will be the “guardian angel” of selling your Timeshares, there are a few chosen firms that I can refer you that use an effective “internet marketing plan” in achieving the goal of selling your Timeshare. Sites such as the link indicated in the author’s bio is highly recommendable and it seems that those professional marketers or consultants have been selling and buying Timeshares for decades and has the greatest exposure in this field.

Once you start selling your Timeshares, the first thing to you must know is that you don’t need realtors or a real estate lawyer or even big realty firms to help you. Those are nonsense.

Let me tell you straight to the point: Dealing with the best experienced online marketers who know the nature of the Timeshare industry by heart is what you need. The best part here is that the company will even pay you out for a certain amount and I don’t know the details here but the fact that paying you out instead of you buying out their services gives the assurance that they know what they are doing.

no wise cracks on that comment :) Actually, no give me wise cracks, this should be fun
Good idea, sue your current students, alumni, and faculty for promoting your half ass college. How does this make any business sense in this economy?
He might have made those comments in a socially appropriate way - by joking. It sounded to me like the author already decided "antisocial nerd" and fished for ways to make him fit.

And if he is an antisocial nerd with poor social skills, I don't see any reason to point it out in the article - it's certainly not going to help him. Saying he's never had a girlfriend isn't just patronizing, it's embarassing. Why even mention it?
I'm not sure that many medically qualified researchers would advocate a diet based on ketosis (a la Atkins). You can have low carb and not go that low.

The example cited is not death by too much success but rather death by not diversifying the product line.
Laid off...Best thing ever to have happened ?
Hey! I am a LAMP developer with some ASP.NET experience under my belt too; today I've been laid off by my firm which is having financial troubles in these times.

I'm thinking to myself that this might be a blessing in disguise, since this might be my chance to move on to something new.

Anybody needs a web-application developer ? I'm looking forward to being part of a startup, preferably and I'm not seeking any money beyond subsistence. (just enough money to pay rent, food, etc. ).

If there's someone interested, kindly bump me at harnal.shubham@gmail.com and I can then forward my resume.
Thanks.
It just seems reasonable that an application has a minimum memory requirement. Is it really so bad on the iPhone that memory can be arbitrarily low? What if the iPhone never gives my app more than 1KB memory? I just see no way to make it run reasonably with 1KB.

Also a crash is different from exiting with an error (although still annoying from the user's perspective).
A U.S. patent application is normally published 18 months after its filing date (or other priority date). Looks like that's what happened here.

In a way, why does it matter if it has paging or not? Either way the total memory available is limited (hard disks don't have infinite storage space).

Well, I really just meant "games". I'm not a game programmer, just an occasional player.

But, maybe I chose the word "simulation" because his works are always grounded in ordinary body physics. The typical fight game is really a button-masher with the reward of seeing a body fall to the ground if you win. Mechner's fight mechanics are about things like leverage, timing, moves and countermoves. They aren't really 'realistic' either but he's going one level deeper.
We take the raw data streams (e.g. a data mining feed from Twitter) and process them, ourselves.
But we know how to build antidepressants which work on everyone.

It took me a while in my offline personal life for the very evident counterexample to come to mind. In fact, it is well known that human mood can go wrong in two ways: by being too low (depression) but also by being too high (mania). To date, there isn't any medication that reliably raises the mood of individuals in normal mood states without subjecting some of those individuals to severe risk of psychotic mania. Anyone proposing policy reform as to this issue should be aware of this fact. Here are some reading references for HN participants who would like to know more about the medical research on mood disorders:

Interesting. I worked in the .edu space before my current company–including working with Blackboard a bit when they were young.

I still think there's a ton of room for new startups in this space–these companies (Angel and BB) are still, as far as I know, very mired in old/web1.0 technologies and methodologies.

The biggest problem is the sales cycle in education is painfully long. It takes months to get a deal started, approved and then paid.

I'm not sure if the solution is to go with a cheaper SaaS solution that requires less approval, but I definitely hope to see some YC companies in this space soon (I have an idea for one but no time at the moment).
Except that the opt-in process enables transparent third party verification. Updates can be tested individually. When an opt-in update misbehaves, word can (and does) spread. It can be avoided.

If a silent update misbehaves, how do we have a chance to -do- anything?
The update was likely applied before we could even open an app to get the news. Should we go online in a VM to verify that it's safe to connect with our preferred OS/software?
This is one of the sessions I skipped at RailsConf ... you should see the twitter feedback (rough)

http://search.twitter.com/search?q=Ferris+%23railsconf
I checked that, and I couldn't find any case where the body _wasn't_ a String.

It's true, that the problem only becomes really glaring when the pages being served are quite large (this example was 1300 lines of HTML), but I still assert that good performance regression testing ought to have popped this up. With 100 lines of output, which is pretty reasonable, you'd still be looking at an extra 10ms on each request.

An incredibly mature attitude about piracy.

My first job was at a chain music store where I became familiar with the term "shrink". I noticed that the most-often-stolen item was cassette singles, which made sense given their target audience. What didn't make sense to me was that they were placed near the entrance/exit, which seemed to make them even more vulnerable.

When I asked the manager why this was, she explained "the margin on those tapes is lower than almost anything else in the store".

Brilliant.
No, we only incidentally found it while working on a piece of our app that serves static files. The issue looks universal to me, although with dynamic content or smaller output, the relative hit would be less noticable.
I don't get any popups in Firefox ever.
Also note that the "birth-death" model fudge-factor they used for April was 226,000 which was about double what it was for March.

Watch out for revisions as well:
"February was revised down from -651k to -681k (-30,000) and March was revised from -663k to -699k (-36,000). See a pattern there? That's 66,000 jobs that were reported as existing but revised out later."

The amazing thing is that there is a lot of repetition even at 10 paragraphs. Some of the other comments here sum it up in twitter-sized chunks.

The missing piece is how to identify over-specialization, and it's missing because it can't be usefully generalized.
This is a fun game to play, actually, any time a new technology is introduced.

Imagine the new technology was invented first, and the old technology is actually the new challenger. What are the advantages and benefits of the old technology you can promote over the new one?

> he doesn't even mention Twitter in the title

Nor Apple!
As the article mentions (and as I've heard from some other developers), pirates are generally the among the first people to buy any app -- they pirate everything, regardless of price.

...It's a pity that Apple probably wouldn't let you submit thousands of applications, as you could make a fair amount of money off of the pirates before anyone noticed.
Their claim is pathetic, based on hypothetical misrepresentation. I hope they save face and drop it, and maybe rethink how how many lawyers a community college needs.

> This is an expenses paid (but no wage) internship

I'm expecting to save $3000 CAD/month this summer as an intern after all expenses (I'm living cheaply, but my wages are quite average). The work I'll be doing is also a great deal more interesting, I suspect, than any web startup could ever offer.

While I would't expect to make as much money if I was working for a startup, this offer is simply a rip off. As reference, personally I would expect to be offered a bare minimum of $12/hour for technical work. That's the level at which I wouldn't laugh in your face and walk off.

If your company is too cheap to pay students working for them, that also raises questions about the sort of work that they would be doing, and now interesting it might be. It also implies strongly that the students would be on a lower rung and would be a "lower class" at the company, with poorer working conditions and a lack of respect.

Overall, unpaid positions without massive perks [edit: or other forms of payment] scream "AVOID!".
For crackers, it's not about the money. It never has been.

To understand anything completely, you need to understand, everything completely.
I do sometimes use psuedocode, especially to either work out for myself a complicated algorithm or help provide additional documentation for readers. However one key difference is instead of unstructured natural language, I use Python or Scheme - this is beneficial for me, because it forces me to concretely express what I am trying to do, instead of hand waving, and for a future reader, who will probably have an easier time unambiguously parsing a real language instead of random half-sentences. And it is often succinct - it is amazing and amusing how often (the gist of) hundreds of lines of optimized C/C++ can be expressed in a line or three of Python.
Does mibbit or chatterous or an Instant message client allow for search of conversations? If not I think all chat clients should make an API to search data, especially links shared in email & chat clients!
I'm not sure why individuals feel the need to write an entire page of text regarding a relatively straight-forward bug fixes. "Improved [Rails|Ruby|...] performance by [X] ms by changing [N < 20] lines of code" posts are becoming a common occurrence.

The regular occurrence of such issues in a project implies an immature, poorly profiled code base, and are the kinds of things that other projects fix without fanfare.

Our most recent database-backed dynamic web application can serve >10000 requests/sec on our mid-range hardware at <2 ms/req, which we achieved by running the most basic of profiling early on and throughout the development process, and using software that does the same. I don't expect a gold star for this.
I didn't feel like getting into the nitty-gritty details of my analysis, but Ruby does have a profiler, and it integrates into Rails quite well, and I was using it together with timers in this investigation. However, the exact same issue applies to the profiler as to simple timers, which is that the 150ms in question happens _after_ Rails hands off the reply to the web server, so as long as you are only measuring within the Rails framework, you will not see it.
I can make some very educated guesses now, and I like where you're going with it.
The guy went to my high school! That's cool, but not that surpsising since they have an excellent gifted enrichment program. That's also why I went there.

In the 12th grade I remember there was a couple people doing cancer research at the hospital and another dude doing some kind of physics research at U of T.

Myself, I was using FEA software to test model aicraft structures and skipping exams to attend competitions. Fun times.
I don't think I ever once had the patience to solve a cube that someone handed me. The puzzle just never interested me, much like a 15-puzzle fails to interest me. But I certainly spent lots of time playing with the mechanism itself, trying to divine how it was built.

So to answer your question I'd have still bought one today if I'd never seen it before, computer games notwithstanding. It remains a clever hack.
I can condense it down into one sentence:
