Seastrom also remembers what he calls the "Site Finder debacle" of 2003 where VeriSign unilaterally decided to serve ads to users who typed in a non-existent dot-com domain name, rather than return an error as internet specifications dictate. "VeriSign would be completely nonstarter [as root signer] for any one that remembers that hack," Seastrom said, adding that any for-profit entity with financial interests in the contents of the zone file should be not be signing it. - alex de carvalho

Palin reinforces the overall message of the reactionary right, which has been in play since 1980, that social justice is liberal-radical, that minorities and immigrants, being different from "us" pure American types, can be ignored, that progressivism takes too much effort and globalism is a foreign threat. The radical right marches under the banners of "I'm all right, Jack," and "Why change? Everything's OK as it is." The irony, of course, is that Gov. Palin is a woman and a reactionary at the same time. She can add mom to apple pie on her resume, while blithely reversing forty years of feminist progress. The irony is superficial; there are millions of women who stand on the side of conservatism, however obviously they are voting against their own good. The Republicans have won multiple national elections by raising shadow issues based on fear, rejection, hostility to change, and narrow-mindedness. - alex de carvalho

On Thursday one of FriendFeed's co-founders, Paul Bucheit, will be on a FastCompanyTV webinar with me along with Matt Mullenweg and Nat Brown, the CTO of iLike to talk about how to make a system that stays up and responds quickly, even with millions of users. I can't wait, but I'm also terrified and need your help. - Robert Scoble
A link from work (Not sponsored, not an ad) for anyone interested. It's related to Robert's topic: http://www.bluearc.com/dataflo... (And don't shoot me for blending the work life with FriendFeed) - Louis Gray
Thanks Louis, checking it out now. - Robert Scoble
I would like to hear their opinions on Rails and if the scalability issue is a myth. - Mona N.
This website may help with your research: http://highscalability.com - imabonehead
Mona, here's a Google video on "Ruby & Scalable Architectures" (note this also includes Rails) - http://is.gd/3A7C - imabonehead
"Breakthrough Failures That Help Sites Scale" - http://is.gd/3A85 - imabonehead
There is usually a session at mix with the myspace crew. It's Microsofy centric bit might help. - Roberto Bonini
Robert, I left you a comment on your blog post - but maybe it'd easier to catch you here. Come on up into the city anytime this week before your interview, and it'd be my honor to help answer your questions, and take you through what we did at Technorati (and now at Offbeat Guides) with regards to building scalable systems - including all the mistakes we made, some of them not so obvious! Give me a ring at 415 846-0232 or DM me or whatever, we'll set it up... - David Sifry via twhirl
I'd ask a simple one about the fact that traffic spikes can happen at any point, day or night, how do they deal it? Do they have round-the-clock staff or any type of early warning system? - Cains
I've built several sites for Yahoo! and give conference presentations on website scalability. Would you like to chat before then? - Glen C
http://blog.broadpool.com/2008... some thoughts on scalability. - Glen C
I have a bunch of conference presentations on scalability; let me know if you're interested (might be too technical for your audience) - Glen C
Glen, I guess many of us are interested so if you can share them we would be very grateful! - Andrés David Aparicio via twhirl
These guys have all answered these questions before and know how to talk about the topic. So I don't think you are on the hook for deep insightful questions. More of just getting the conversation started. Maybe take it from an uber user point of view and ask for stories about how they've scaled, made performant, and made reliable some of your favorite features with special attention to challenges and how they were solved. The proud parents will do the rest. - todd
All this time I thought Glen was just this funny guy on Friendfeed :) Love the anonymity! - Charlie Anzman
There's some excellent videos over at parleys.com, especially: http://parleys.com/display/PAR... and http://parleys.com/display/PAR... - Jason Carreira
http://files.broadpool.com/ has directories for various things. "dcphp2007" was a presentation entitled "Drinking from the Firehose"; "phpconference2008" was on service-oriented architectures; "webinale2008" was on the best ways to bring down your website (and how to avoid them). - Glen C
Scalability is about identifying bottlenecks that keep the system as a whole from achieving the goal of linear scalability (adding 2x as many boxes gives 2x as much throughput). Ask about what typical bottlenecks they avoid, and which bottlenecks they're still fighting. Also, the largest cluster-size they've run, and where the tipping points are for when certain bottlenecks become a problem. - Jason Carreira
todd, -10 for using the word "performant" :-) - Glen C
Allow me to mix together a few prior comments by pointing out this great article: "Scaling Bumper Sticker: A 1 Billion Page Per Month Facebook RoR App " http://highscalability.com/sca... - Daniel J. Pritchett
Glen, Jason: thanks for the links :) - Andrés David Aparicio via twhirl
Anytime Glen. Creative blending of obsfucation and bloviation is a talent :-) - todd
I think a good question to ask would be what assumptions each of them made that ended up being wrong and the most expensive to fix? All developers/architects make assumptions ... about how much traffic they'll see, what kind of traffic they will see, what the most important performance metric will be (the responsiveness vs. throughput question, which anyone building a scalable application needs to answer for their domain) ... Did any of their assumptions in these or other areas lead to big problems? - J. McConnell
IMHO the biggest problems I've seen with up-and-coming web apps is that they tend to think of scalability as something you "add on" instead of something you build in. If you've designed the architecture properly, you can increase the scale by simply adding hardware; any solutions that require additional coding or extra software (i.e., "just recode that using memcached") simply are not properly scalable. - Glen C
Glen, maybe the reason they're up-and-coming is that they're thinking in terms of value to the user, and not thinking, e.g., "how much harder will it be to shard our data if we implement this feature?" - Bruce Lewis via fftogo
Mr. Scoble - If I had one question to ask it would be "How do you BUILD for an predictable spike?" Say you're WalMart.com and you KNOW your biggest day of the year is going to be day after Thanksgiving. Walk us through preparing for surviving the spike and servicing all the transactions. If I had time for a second question I'd ask about the current state of cloud computing (namely Amazon's EC2)? And, a third question would be framework related (ala Ginger or MaryAnn?).... Rails or C? - Gerald Buckley
Bruce, absolutely true; however, it's actually cheaper to build scalability in at the beginning than to add it on later. And it doesn't have to be more difficult (sharding data? no one at Yahoo! does that, so why would a smaller company need to?), just a different architecture. - Glen C
I'd suggest that database sharding is a bandaid solution for the wrong up-front architecture. - Jason Carreira
My main interest in scalability (and the most problematic in my 10 years of experience) is always the database. I'd ask if there's a rule of thumb for the design of databases to support a truly scalable application. - JungleG
Scalability is all about CAPACITY PLANNING. Numerous aspects of systems design (and potential failure) must be examined and well planned in order to avert potential future failures. In an ideal world, you'd know the limits your system will need to scale to. But we don't live in a perfect world now do we. So product managers must work with IT architects to build a system that can "scale" to meet burgeoning demands as their product "takes off". Get your crystal ball out to start forecasting demand. - Susan Beebe
Cont'd: CAPACITY PLANNING involves all 7 layers of the OSI model. GO from the electrical plug in the wall to the "presentation" layer (screen) of the customer's view of your product. Now consider all the potential SPF (single points of failure) along the way; whether that be core infrastructure issues like bandwidth, load balancing (web servers handling the load), memory caching, DNS, optimized O/S, application design, database design, well structured queries, smart technologies like Java and AJAX - Susan Beebe
SCALABILITY actually refers to the concept of a Production Application running withing acceptable SLA limits without downtime or performance degradation, which can be caused by a slew of offending issues. Volumes have been written about scalability. Focus on key bottlenecks: bandwidth, infrastructure hardware, application design, data storage, especially as it pertains to database / query design. Sometimes large queries, reports, sprocs, batch jobs can hose a good app (needs smart devs to optimize). - Susan Beebe
Where are your users and where are your servers? Scaling globally. When did you move away from managed hosting and run your own racks? What do you consider successful site responsiveness? Have you noticed positive correlation between really quick page loads and user engagement? - Niall Kennedy
Great webinar, Robert, I posted some of my thoughts here http://cli.gs/L4bDzV - JungleG

This implies spending less, saving more and selling assets. But the trouble is that banks and consumers alike are trying to lighten their debt burdens at the same time. It is not impossible, and it does not even mean a terribly long recession, though we are probably in for a long period of weak growth. What it does imply, unless the U.S. Federal Reserve can somehow pull a new bubble out of its hat, is the return of boring old parsimony. Stocks will struggle during the transition from excess to frugality, but once we are there, the rally could be huge. After all, by that point stocks will have more than a decade to make up for. - alex de carvalho

"The ideal situation is to have the legislation published online immediately." Miller says. "Our position is that every piece of legislation should have a minimal online-public-availability time of 72 hours, which would give citizens and lawmakers a chance to read, digest, think about and comment. There's no better place to start with than with this bill that involves hundreds of billions of dollars and affects the lives of everyone." - alex de carvalho

Latest ABC News/Washington Post poll: Obama 52%, McCain 43% - Andrew Baron via Bookmarklet
I pray this is a harbinger of what's to come. - Dave Hussein Winer
Too bad this race is being decided on marketing and not substance. Because Obama is nothing but an empty suit. I'm sure that ABC poll oversamples democrats as usual. - Spencer Scott
@spencer, and how would you describe McCain? - Andrew Baron
Spencer: well, McCain is a bigger asshole than Obama, so, marketing or not, it's a question of choosing the better of two evils. - Marcos Marado
Wish I could have gone one election without hearing the "two evils" moan YET again - Christopher Galtenberg
I'll take an empty suit over a deranged nutjob who'd rather WIN the election than pick the best qualified candidate for the VP job... - Jeremy Toeman
If God wanted us to vote, he'd provide us with candidates. - Jason Shultz via twhirl
Really fascinating to watch all you good people deal with the troll, who I blocked, and can't see. I encourage you all to do the same. It's pointless to argue with trolls. It's not like one day he's going to say "Oh I see your point now, you're right, I change my mind and by the way I'm sorry!" - Dave Hussein Winer
So Winer, anyone without your far left viewpoint is somehow a troll. Got it. Why don't you toss in the race card like Obama does? How about some of you name some accomplishments from Obama? - Spencer Scott
guys, let's not - esp on Andrew's thread - take it to your own, if you must - Christopher Galtenberg
Rasmussen has it Obama 49% McCain 47%. Gallup is Obama 47% McCain 44%. - David Ward
@Spencer - how about you explain to us how McCain is doing the best for his country in selecting a woman who is clearly power-hungry, deceptive, and uninformed (at best) as his #2? - Jeremy Toeman

They are using private jets - they could make the vote and then go to the debates. Also as party leaders could they not again congress to agree to vote on Saturday instead? - Ruth Ferguson
It's a smart move strategically. And Ruth - delaying a crucial vote like this, one that could very well sink or save this country, for a debate would be lunacy. We need a decision and a plan ASAP... - Ben Parr
But Ben we were told that on the Iraq vote. I would rather have careful consideration. Not someone yelling at me: now now now. Frankly I would rather have the vote first. - Ruth Ferguson
So what you are saying he is putting election first, country second? that is what i think he is trying to be strategic b/c he is getting slaughtered in the media this week. I hope Obama does not fall for this. - Ruth Ferguson
Ben: neither of the candidates are on the Senate Banking Committee (which is who will be involved in the discussions). How will their absence affect a committee to which neither of them belong? - Stupid Blogger (aka Tina) via fftogo
+1 Tina - Nathaniel Payne
Don't believe the hype. How do we know there's an immediate urgency? How do we know they need $700B all at once, and not smaller amounts in tranches? How do we know this is the best plan? A modicum of skepticism would serve us well right now. Not holding the debate is yet another maneuver to distract us and to instill fear. Politics as usual, once again. - alex de carvalho
mccain is buying time and looking to re-energize his campaign after last week's lies. nothing more than that - Cee Bee
Tina: Obama and McCain are the two most powerful men in the United States. More powerful than Bush, Pelosi, or Reed. What they say and do in those halls is going to sway nearly all of the Senators and Congressman to their side. They actually hold all the cards if they so choose to utilize them. - Ben Parr
If McCain can't handle two things at once, I suggest he not run for President. - joshua m. neff
I've been reading and listening to the reports coming out the Senate Banking Committee, and it sounds to me like they're handling everything just fine. They are all--Democrats AND Republicans--asking the same, logical questions they should be asking. Why this much money? Why so soon? Let's explore other options. Etc. They don't need two Presidential candidates showboating for the cameras in parallel desperate attempts at appearing "presidential" about this issue. I say, carry on with the debate. - Nathaniel Payne
i think suspending his campaign and calling for a delay in the debates is showing he's not ready to be president. you can't call a timeout then. - Faboo Mama
Ben: if that's the case and they each hold that much sway with the other members of Congress and the Senate, then why do they have to be in the halls to make their opinions known? Wouldn't those same opinion's and strategies be aired in Friday's debate? - Stupid Blogger (aka Tina) via fftogo
I thought he invented the Blackberry and thus understands that in the 21st century one does not need to be physically in one place in order to do a job there. And, as a fighter pilot, he is probably aware (unless he forgot by now) that it is possible to go from D.C to UMiss in an hour or two. - Bora Zivkovic
It also allows him to stop spending on advertising and force Obama to do the same, as he is so far behind in money. - Bora Zivkovic
But, as long as he keeps his campaign suspended until November 5th, I'm OK with it. - Bora Zivkovic
+3 Bora! Indeed, why not just Webex/Raindance in to the hearings? At least then they could spend some time catching up on emails, too :P Oh wait, McCain doesn't know how to use email. - Todd Harris
Shows McCain is not ready on day one.. - Darryl
Why the hell didn't he start "focusing" on the economy two weeks ago? -- seems to me what he ought to be proposing, if he were sincere, would be to hold a debate on the economic and financial issues. Contra Ben Parr, I would say an honest debate is PRECISELY what the country needs. - Nathan Rein
looks like McCain believes that he belongs in the Senate - Nailed Jello
agree @Nathan Rein. Debates cost universities millions of dollars and lots of work - canceling is irresponsible, but changing the topic from foreign to economic issues would be just what the doctor ordered. - Bora Zivkovic
from abc news: However a senior Obama campaign official said Obama "intends to debate." "The debate is on," a senior Obama campaign official told ABC News - bob frasier
Of 643 votes taken this Senate session, McCain's missed 412, more than any other Senator. NOW he thinks it's important to be in the Senate? - joshua m. neff
+5 Joshua Neff - Matt Hamilton
+152 Joshua M. Neff :) - Nathaniel Payne
thank you joshua! he hasn't been "active" since april and by active i mean in the building - Cee Bee

In its latest explanation, Tribune said a single visit during a low-traffic period early Sunday morning pushed the undated story onto the list of most popular business news of its South Florida Sun-Sentinel newspaper's Web site. About 30 minutes after that visit, a user viewing a story about airline-cancellation policies during a storm-ravaged weekend clicked on the link for the old story. Seconds later, Google's automated search agent, Googlebot, visited the Web site and found the story. Soon after that, the story became available through Google News, and by Monday the article became more widely distributed to users of Bloomberg LP, the financial-news service widely watched on Wall Street. Tribune said it previously had identified problems with Google's automated search service and had asked Google to stop trolling Tribune Web sites for inclusion in Google News. - alex de carvalho

McCain’s persistence in pushing dubious claims is all the more notable because many political insiders consider him one of the greatest living victims of underhanded campaigning. Locked in a tight race with George W. Bush for the Republican presidential nomination in 2000, McCain was rocked in South Carolina by a whisper campaign claiming he had fathered an illegitimate black child and was mentally unstable. Shaken by the experience, McCain denounced less-than-truthful campaigning. But McCain and his running mate Palin, the Alaska governor, were defiant this week - alex de carvalho

The guy you call “boss,” who incidentally wears a monkey suit every day to work, says that this year, you’re worth a 5% raise. Who the hell is he, anyway? Who is anyone, for that matter, to tell you what you’re worth? This seems like a ridiculous concept to me. Each day, you go out and determine how much you’re worth.

journalism wasn't meant to be a conversation, anyway. It was maybe a monologue, at its most democratic a carefully constructed dialogue.
