For at least the first half of it's life, wikipedia grew at an astonishing rate precisely because it wasn't being moderated by pedantic self-appointed editors.

This is simply factually not true. If anything, Wikipedia is considerably looser on inclusion standards now than it was a few years ago. Most of the people with more traditional views of inclusion standards left around the time that Larry Sanger forked to form Citizendium, plus a few waves after that. It's also gotten much more permissive than it used to be when it comes to things like covering famous internet memes (which used to be deleted on sight).

Things Founders Can Do for the Startup Ecosystem
NO - 3D secure is not good for the customers.

the system has no safeguards for vulnerabilities like man-in-the-middle,etc. attacks. Yet it gives credit card companies, the right to deny chargebacks to customers (whose credit card was stolen/hacked) because they can now wash their hands off the matter ("hey only the customer knew the second password... he must have been careless with it, not us")
I have been reading books about Scala and used it for scripting here and there. I gained some Scala experience over the last years, yet it still amazes me how often people state:

"Scala is not ready yet, but when it is, it is gonna take over Java as the next big language".

Years have passed and this has failed to materialize. Maybe it will never be 'ready enough' to take over? What do you think?
I feel this is a good thing!

If you are stupid enough to fail to use and understand the new system, they you wont be able to purchase it.

And thus they will end up avoiding huge credit card debt's like poor Americans.

Also hardly anyone buys from Amazon and only pathetic people buy from apple iTunes.

It usually is :) but cleartrip might just be right here to blame the banks. Asking for more secure authentication is a good idea, particularly in India where on more than one occasion, I've had to stop people from writing down my credit card number for "the record".

That transaction volumes decreased on the /first/ day 3-D secure (and now, the one-time password) was implemented is hardly surprising, but I think once customers get used to it it would have returned back to normal.

A question I hope someone here can answer:

I'm now working on my first major webapp, so I've been learning how to be a sysadmin, pretty much from scratch (almost no previous experience with running webapps, lots of experience with other things though).

Anyway, I've been trying to find resources to help learn, but it's been extremely difficult. These are the questions that are still bugging me, hopefully someone here can point me to some good reading about them. Note that my stack is Python/Django over Apache (mod_wsgi) right now. Also note that my site has a "ping" system, where each client connected continuously pings the server every few seconds to see if any new info arrived, making me have to handle a larger amount of requests per second, I believe.

The questions:

1. What kind of load do I need to handle? Is 12,000 requests per second terrible/good/great performance? How do I go about figuring out how many people are online at once for most sites? How do I even estimate it?

2. How can I test the performance of my application? I've learned that Apache Bench is used a lot, but are there better tools?

3. What are the best tools to help me monitor and understand the load on my server?

4. How do I go about understanding the bottlenecks in my application? Right now, my Apache process is taking most of the cpu. What does that imply about where I should optimize?

Sorry to braindump, but I've been looking for answers to these questions online and haven't found any clear help.

Bought the first from makerbot, was a huge pain and disappointment, but it got me as far as printing the parts for the second one, a Reprap Mendel. That one in turn printed me (and a number of other people) the more streamlined Prusa Mendel. I'm a contributor to the Prusa variant (I wrote the build documentation and the makefiles, and contributed to some of the parts), but did not design it. So yes, as others said below, I have two repraps (and one non-reprap), and I did build them myself.

3D secure is not very user friendly at all. Most users aren't setup with 3D secure details or have forgotten the necessary details to use it.

Perhaps it's a good idea in principle, much like OpendID, but in the real world it's a pain to use for everyone involved.

Indeed, but with clever design you can avoid support material during builds and still get adequate results.

I fully agree that you can get lattice structures in a number of processes, but printing is the only reasonable way to get internal, closed lattice structures. And I believe the article was meant to create awareness of a reasonably unknown process, rather than claim that everything else should step aside. Milling, routing, turning and molding aren't going anywhere. But that doesn't make printing any less impressive in the areas it's good at.

FDM scales linearly, which is a good thing and a bad thing. It means you have no cost savings when you make large quantities of the same object, but it also means you have no additional cost to make a different object every time. That's what I think is most exciting about it.
Pattern Matching Database Records with F#
Um, but varnish is just a cache and so of course it's faster for static content? Or am I missing something?

Litespeed can work with php several times faster than apache+php while serving dynamic content (and so can nginx).
we started using apache and fastcgi php in feb 2001.
since memcache didnt existed yet or at least we didnt knew about it, we used ram disks to temp store things like logs and had logrotate get rid of it and in addition shared mem within php. we hand compiled apache with every available cpu flag we could find to get it down to a 400kb bin. we adjusted everything we could on the network settings.
two servers, 2gb ram, dual core amd64.

answering 12k static req/sec and around 3000 dyn req/sec.

it took most of the internet another 5 years to understand this. since that time i feel kinda like a guru.

we also were first to adapt lighttpd in 2006/2007 on a large scale ad server.

and im working on implementing node.js at the moment.

you just have to stay cutting edge. saves you a lot of money too.

(fyi: he's not mentioning if keep-alive is on or off. most likely its on, means the benchmark is kinda off because he gets served straight from system cache after the first request)

You are arguing against a straw-man. I wasn't talking about the standard. The behaviour is, as you say, implementation defined. So, Microsoft are perfectly free to implement volatile access from multiple threads as re-formatting the hard-drive or whatever.

What I did say is that Microsoft have chosen to implement volatile access in a way that is incompatible with other compilers. Their choice to put the barriers in for you is certainly well-intentioned, but really just complicates matters.

> The reason it will (supposedly/hopefully) be different next time is that management overhead, bureaucracy, and outsourcing are killing their software development. If they actually can cut through the red tape, then I don't see it as very far-fetched to say that they can come back as a mobile software shop.

sorry, this just sounds like hot air. anyone can say things like "management overhead" and "cut through red tape", but without a solid plan what exactly does this mean?
India has a lot of public policy mishaps such as this. It seems that the people making these rules oftentimes don't do adequate research regarding what's feasible for such a large developing, and rapidly changing country.

A couple of other examples:
There was recently a rule to limit SMS spam by limiting each cell phone to receive a max of 100 texts per day, there still is a rule where you can't entering the country twice within a certain number of days without getting prior permission, IIT students were arbitrarily limited in the number of hours they could spend online because some administrator thought they should get out more, etc.
Well we won't sue anyone, but the idea is that once the site becomes competitive, we can start pushing the top neovellas through Amazon Singles and then use the percent share calculation we have to distribute a share (more than our own) of royalties back to the authors in proportion to their contributions to the entire collection of short stories.
Actually he is totally serious, Apple has already stated that this functionality is on the Lion OS roadmap, just replace android with iOS
While that is true, European cities tend to be more compact, with more 'empty space' between them. When I moved to the US, the concept of 'urban sprawl' was completely new to me.

This should increase the meaningful population density, as there is little need to have high bandwidth in uninhabited areas.
Some of us are already doing that. Check thingiverse.com for example.
I have both an iPhone and an Android with dozens of apps on them.

But I could do without all of them, all I need is an Email client + a browser + a Skype client.

If you build a usable/reliable OS with a usable browser and email client, people will buy your phone and devs will come.

WP7 is not even on the radar yet for developers. Porting apps to WP7 for me is waisted effort instead of improving the code-bases for Android / iOS (which also have shared logic that I cannot port easily to WP7 because WP7 doesn't allow native code).
Wow, I haven't run my own webserver in a while, but if what you say is true it's remarkable that Apache can be so bad.

If Apache really uses 7-9x more resources than nginx, that speaks more to Apache's awfulness than nginx's awesomeness. You can beat a worthy competitor by 50%, maybe even 100%, but if you're winning by 700% then your competitor is just bad.

I wonder what it does that is so inefficient.
The question is do you feel you are ready to start your own business or is it just the fact you lost your job.
My advice to you, having the idea of starting your own business is great and I encourage to do this if not now maybe later, the feeling of satisfaction of doing something you are passionate about is unlimited and will always drive you to do more.

Starting business is not only about knowing what you want to do or how to do it , there is many factors you need to know before you start your own business, like business itself, law, finance and management.

Look for a good job in the same domain you want to start your business in and start planning your business accordingly, and try to get involved in everything required from you to succeed.

Having your goals set in early age is great.

Good luck.

scala is quite complex. it has O(m + n) complexity from functional and "object oriented" (single dispatch, backported type system) requirements, plus whatever their interactions cost, plus the novel shit. I admire anyone who really grasps it in it's entirety.

as a mere mortal I gravitate to simpler things.
If you want the best user-experience, you have to use the OS-specific APIs.

Otherwise your best options are Webview components + HTML + Javascript + some native hooks to provide the missing functionality. Works quite well, take a look at PhoneGap + JQuery mobile / jQTouch.
Actually, European carriers are often required to let other providers use their network infrastructure at wholesale rates. Hence, if they are expensive, they will get competition from within their own network.

Contrast this with the network monopolies in the US where every (both!) carrier can just make up prices and there is nothing any customer can do about it. This is most certainly why prices are so high in the US and why carriers see little incentive to upgrade their infrastructure.
Agreed. Usability with 3D secure is not bad at all. Breaking the "subscription" model is actually a good thing in the current scenario, where the customer has very little control on when and how he unsubscribes to services, and businesses unscrupulously charge for subscriptions beyond the agreed-on date. This happened recently, when a web hosting provider tried to charge my credit card although I'd canceled - I got an SMS from the bank saying that the charge had not been accepted - how delightful it feels to be in control!
I have stopped using credit cards online for over a year, prefer online banking based payments, because it is one username and 2 passwords(authentication, transaction)

I dont like 2 factor authentication, especially with mobile/sms, when I am abroad or travelling, I still can do my transaction

Completely different to standards-compliance, yes. However it is exactly the same thing as GMail's alphanumeric only rule.

To reiterate - the mailbox names that a email provider will provide are subject to the naming conventions defined by that provider. Whether the convention is firstname.lastname; 5-7 characters only; alphabetic only; or 13375p34k transcriptions of characters from Lord of the Rings. None of that has anything to do with whether they are standards-compliant.

The test is whether they will send email to any RFC-compliant email address regardless of whether it conforms to their own mailbox naming convention. Gmail does.
Am I the only one who doesn't really like the name MeeGo? I don't know anything about it beyond the wikipedia page nor am I making any judgement regarding it as a platform, but I think the name is kind of goofy. Haha.
That's why I said "games", which are written in C++ and for which you only really need OpenGL ES. Other differences can be easily abstracted.

And when speaking about "games", they have their own UI, so providing an optimal UX is not about using OS-specific widgets.

Seriously, why aren't there any decent ARM laptops?

Because demand is extremely low? If it can't run a mass-market OS, anything you make is going to be an extremely niche product.

I like the idea of an Android laptop, but I wonder how well off-the-shelf Android applications would perform on a 16x9 landscape screen with a hardware keyboard and a hard-to-use touch surface.
This.

My laptop doesn't need to be a CPU monster. I'm mostly using it for SSH, vim and surfing the web. And I hate it when the thing heats up like an oven - especially in the summer. (No AC + summer temperatures + aluminum case = inconvenient).

Just give me an ARM-book pro - without an optical drive but with an enormous battery ;)

It's Dell. How passionate are people about new features in Dell products? I don't even know who Dell's CEO is. Dell is boring office stuff.

On the other hand, if Apple would have introduced such a feature we would be hearing from it on TV news. And all tech bloggers would jerk in a circle, etc.

I agree with your point I have found it hard to prevent merchants from writing down credit card numbers(!!!) and these additional layers of security are needed for the market.
On the contrary, though I am a regular user of credit / debit cards for online transactions in India - atleast 3-5 times a month, I have found it really hard to use my credit card from the beginning of the month since they introduced the one-time-password.

I have not been able to use my credit card even once since this was introduced due to various reasons - the SMS service that banks are supposed to deliver One-Time-Password is not sent promptly or I do not have a way to get password to authorize even an IVR transaction in time.

It might all work out after initial issues are resolved but so far I find this to be a pain.
Racket seems to be really neat with support for features like JIT and futures (which have been around before 5.1).

The other day I tried a simple benchmark (nothing elaborate - just fib) and found it to be significantly faster than Python. Unfortunately I don't have the numbers right now.

Does anyone have any experience to share regarding the use of Racket in a production app?
I agree with PG: just ignore patents when you're small. If you ever get big enough for it to matter than things are looking really good and you'll have more bargaining options.
It is as anecdotal as anecdotal gets but I wouldn't be surprised if there was a grain of truth to it. McDonalds franchises are expensive by American standards. They are even more expensive by poor country standards. So one has to be pretty rich to open one.

In my experience the way people stay rich in poor countries is by sucking up to the government. And the best way to suck up to the government is by outing dissidents. So while I doubt it's corporate policy I can see how it would happen.
Man, that's the kind of idea that gets people to quit their jobs and live out their lives as struggling indie game developers. Of course the character would have to be named Fykel Melps or somesuch, but it would be a huge hit with a core gamer demographic: stoners.

> In 2011, "fat nerds" can wield quite a bit of financial power.

While that's true, "fat nerds" (or skinny nerds, or greasy nerds) don't generally do things which display this power. I've met nerds who are effectively retired at 30, fat and happy, who are entirely off the radar of women looking at suits, cars, and Stanford MBA attitudes.

My point is that even though socially we understand that "nerds" have good odds of being reasonably affluent, there's still an awful lot to the "sexy" equation that they don't have.
Actually in some ways it is getting easier (for the geeks, anyway):

* adblock - no stupid commercials for fastfood places, etc
* Downloaded tv (whether brought from iTunes or downloaded from thepiratebay.org) doesn't contain commercials.

Add that a personal mp3 player means you are less likely to hear radio and it becomes that much more difficult to sell you stuff.
