A practical scalable distributed B-tree - http://www.hpl.hp.com/techrep...
Nagender Parimi, binic, Dmitry 'radiant' Volkov and 76 other people liked this
"Moreover, our algorithm is conceptually simple: we use transactions to manipulate B-tree nodes so that clients need not use complicated concurrency and locking protocols used in prior work. To execute these transactions quickly, we rely on three techniques: (1) We use optimistic concurrency control, so that B-tree nodes are not locked during transaction execution, only during commit. This well-known technique works well because B-trees have little contention on update. (2) We replicate inner nodes at clients. These replicas are lazy, and hence lightweight, and they are very helpful to re- duce client-server communication while traversing the B-tree. (3) We replicate version numbers of inner nodes across servers, so that clients can validate their transactions efficiently, without creating bottlenecks at the root node and other upper levels in the tree."
- Paul Buchheit
Paul, I think many of us are going to trust your opinion on this white paper. All Greek to me.
- Jon-Paul Bussoli
All I understand is that it is in my best interests to cheer for the way you access B-tree nodes in order to continue to enjoy friendfeed reliably. Go friendfeed algorithm go!
- Jon-Paul Bussoli
What, no comparison to BigTable?
- ⓞnor
@nor It's really not the same thing, unless somehow you're using a distributed B-tree on hash collision, however, if you're getting that many collisions, then the hash algorithm is probably wrong or your key width is too small. Then again, I really don't know what I'm talking about.
- Eric Florenzano
Curious as to what problem Paul is looking at... My default data toolkit these days would probably include sqlite for in-memory data, sharded bdb's for btrees that are too big for memory, and hbase/hypertable for a distributed store. I wonder where this fits in...
- DeWitt Clinton
Ok this is a really *nerdy* post! :*)
- Susan Beebe
DeWitt, I just thought that it looked like an interesting paper. As for the several solutions you mention, I don't know that any of them have distributed transactions (maybe bdb, but that doesn't really work).
- Paul Buchheit

@DeWitt - no room for a traditional SQL based database except as an in memory database?
- Nick Lothian
we had designed and implemented distributed tree control, but transactions were considered "too much" for near-real-time, and they were already in protocol... the rest you know as xGSN boxes in GPRS/3G/HSDPA - dynamic routing for mobile packet networks. I'd left team in 2003...
- A.T.
@paul - I'll readily admit to being out of my depth, but it depends on what the definition of "distribution transaction" is. With bdb a combination of local transactions and guaranteed consistent replication you can approximate a distributed transaction at the cost of speed. See http://www.oracle.com/technol... and http://www.oracle.com/technol.... But those won't work across bdb shards.
- DeWitt Clinton
@paul - A table-based distributed store can do this via a lock on entity groups, where entity groups are defined by relationship formed by instances of similar models that belong to the same parent-based ancestry chain. This is how App Engine transactions work -- see http://code.google.com/appengi... and http://code.google.com/appengi.... Ping ryan for some background there. Not sure if hbase or hypertable support this via their api.
- DeWitt Clinton
@nlothian - I dunno. Offline maybe?
- DeWitt Clinton
DeWitt: have you ever successfully used BDB with millions of newly written entries and transaction support turned on? We kept getting transaction logs with millions of entries that were never consumed, so restarts would take hours as it replayed the logs. Configuring BDB to work for large databases is insanely esoteric to say the least, and it may be impossible to get it to work acceptably in some cases.
- Bret Taylor
@bret -- no, definitely not with large databases. We used bdb's heavily at my last company, though. Aggressive sharding is the key if you want to support either transactions or replication, which matches intuition about how it is implemented.
- DeWitt Clinton
But your comment about millions of entries makes me wonder about which data is getting written to which place. I suspect a lot of problems like this end up with the bulk of the data being written transactionless + replicated to a table-based store (or a transactionless bdb), and only a small subset of the data gets transaction support. So multiple datastores. But you guys know this better than I do, so why am I rambling? : )
- DeWitt Clinton
DeWitt, you can also look into all the trouble that Gaia had with bdb - I simply wouldn't trust any fancy bdb functionality.
- Paul Buchheit
Also, AppEngine transactions are limited to a single "entity group", which I assume means a single BigTable tablet. Essentially, they solved distributed transactions by not having them -- all transactions must be local to a single tablet. From the docs: "Every entity belongs to an entity group, a set of one or more entities that can be manipulated in a single transaction. Entity group relationships tell App Engine to store several entities in the same part of the distributed network."
- Paul Buchheit
@paul - yup, that's the trade-off. Entity groups ensure locality, locality makes transactions fast(er). Same old lever problem -- speed of consistency vs. scope of the transactions.
- DeWitt Clinton
DeWitt, there's nothing wrong with having local transactions -- I'm just pointing out that they aren't distributed transactions.
- Paul Buchheit
Point taken. I got way off-topic regarding your original post anyway.
- DeWitt Clinton
The design seems reasonable. The only part that is under-specified is the way they switch from a master node to a slave. I'm curious why they don't use transactions to maintain replicas but instead rely on some unspecified master/slave replication scheme.

Palin, and McCain's real sin in the eyes of many is that they refuse to feel liek they are bad people or that the USA is a bad puppy who must humble itself at the feet of European public opinion. These days pride in the USA simply will not be tolerated. As for her abuse of power? Every supposed case of this so far has turned out to be overblown or outright fabricated. Whereas Obama's acceptance of huge sums of lobbyist money and requests for earmarks is a actual fact. Glass houses and all :)

Point that microscope at Obama and you'll see someone who has abused power and tied his fate to special interests and lobbyists in order to trade money for votes and support. But, Obama is a good person who occasionally does bad things for the cause, whereas McCain and Palin are bad people, no matter what they have done, or do. It's just that simple in the eyes of the Left.

- David Vasileff
That's it ... no more hikes in the afternoon! (Sharing .... )
- Charlie Anzman
theory 1: a single "meta feed" which you can poll to get a list of other feeds that have changed recently. (would it cover all feeds on the service, or would FF somehow supply a list of all the feeds they're interested in?) theory 2: a callback/ping/PIMP notification when a feed or feeds change (HTTP? XMPP?). theory 3: a formalization of the "public feed" concept, where you roll every (public) update on the service into a single (rapidly rolling!) feed which FF polls and gets updates for.
- ⓞnor
Someone has to talk to someone to indicate a change occurred, so you can't skip that step, be it push or pull. So my guess is it's a way to get a larger aggregated chunk of what has changed and an idea of the size of the change. What might work is a bulk push of what has changed and then a pull of the changes at FF's leisure.
- Todd Hoff
Providing facts is just cheating. Now there's no room for rampant speculation :-) Add a sequence number and you could know if you missed an update which would indicate polling needed to occur or perhaps a download of the old change notices.
- Todd Hoff
great stuff. imho, when adopted, SUP will be - to the organic growth of services updates - like traffic lights to crowded intersections. or like how gps navigation is to asking people for directions :P
- Dani Radu
Sounds like it's a protocol that others will need to implement and support so friendfeed can process feeds more efficiently. alot of the issues could be fixed if if-modified-since was used and rss feeds were treated more like a web service rather then a static html page, most are generated from a db real-time anyway. Read RFC 977, NNTP fixed this issue by setting up an easy way to poll what's new back in the 80's.

- Susan Beebe
Shawn, we actually already use If-Modified-Since and many sites do properly support it. The key difference with SUP is that it allows feed consumers to monitor many thousands of URLs with a single GET, which is not possible using If-Modified-Since.
- Paul Buchheit
If anything, it shares a few similarities with Sitemaps (which enable webmasters to notify search engines of modified URLs, etc.) Great work on SUP!
- Aviv
This is one of those simple ideas that one wonders why no one thought of before. It's a good proposal and a required one in the rapidly growing aggregation/Lifestreaming world. I am sure the proposal will be widely and quickly SUPported. Well done folks.
- Vinay | विनय
paul, I found and read the ff blog post, and I understand the meta-feed approach. Interesting but I think sup-id storage adds a bit of complexity. Even though the sup-id keeps the size of the feed down, full uri would be better. I think the concern about exposing usernames is a little overdone, I mean it's not going to really stop someone who wants the usernames from getting them.
- Shawn McCollum
Love it. We've used a different approach to interface with "friendly" crawlers, one that is based on the ability to fetch older items in the feeds by request. But it requires a public "recent" feed, and does not work solve the private URLs issue. This is so much better. We'll be experimenting with SUP and would love to help it mature into a well defined spec.

The Amazon link is a bait/switch, it's for an N90 (35mm camera) not the D90. ;-)
- cmiper
grrrr.. is that right cmiper? it said they had one left. I'll have to try to search for it someplace else.
- Thomas Hawk
Regardless of your brand... this means all sorts of win for the consumer :)
- Johnny Worthington
@Thomas - They do have a listing for D90, it's atleast 100$ less then the cost quoted in your blog post (for version with Kit) and less than 1000$ for non-kit body only version.
- Yuvi
ok, looks like the price is actually $999.95 on Amazon, but that it is out of stock. I fixed that link. I'll go check over to see if there are any available at B&H.
- Thomas Hawk
hmm. B&H isn't showing a listing for the D90 yet. I guess it will probably be a few days before these start showing up for sale.
- Thomas Hawk
John, you are absolutely right. This is a huge win for the consumer, video and geotagging now raises a new bar. I will be very interested in what Canon brings to the table with the new 5D likely to be announced at photokina next month.
- Thomas Hawk
Also, I'm wondering how GPS will work when you want to use another flash in the hotshoe (the GPS addon plugs in to the hotshoe)
- Yuvi
Ok, the Nikon Press release confirms the $999.95 price point: http://www.imaginginsider.com/...
- Thomas Hawk
Hmm...didn't realize it had GPS. That certainly makes it more intriguing.
- Matt
GPS is *awesome* it would save me a lot of time having to manually geotag my photos. This is some of the best camera tech news I've seen in a while.
- Thomas Hawk
Wow, great intro vid. I wonder if it's worth switching to Nikon...
- Michael
phenomenal! The video was so cool and the Blakes rock. Now to convince the girlfriend to buy the camera!
- Randy Ksar
Michael, I wouldn't until at least Photokina :)
- Johnny Worthington
@Micheal - GPS on the unit apparently uses EXIF, so Flickr and co should be able to pull those up without much trouble.
- Yuvi
Ha, like I can even afford the 5D now... I did just get some new Canon Lenses though.
- Michael
As a long time Canon user (i had an A2 SLR) I've been pretty jealous of the Nikons since last year. It seems Nikon has really stepped up to the plate, and Canon isn't answering. I'm not going to go switching my gear or anything, as I have the lenses, but still...I guess this tit-for-tat is pretty typical and in a year Canon will have some of these killer features.
- Todd
GPS with auto geotagging is something that willbe needed before I upgrade from my 20D. Lots I good features already but nothing had come out yet to make it worth my money to upgrade yet.
- Dean Clark
Time to upgrade the D70s
- Eric @ CS Techcast
@yuvi... the GPS unit is not required to mount on the hot shoe. That is purely for convenience. I would prefer to have it attached to my strap, which could easily be done with a rubber band, or even a bicycle inner tube.
- Neil Bernhart
This is screaming to stream video live to the web....maybe bluetooth connection to a smartphone?
- Jamie Ginsberg
@Jamie Just wait for a revision (if it needs one) of the EyeFi SD-Card :)
- Holger Eilhard
Looks like time to start saving
- Zach Chisholm
want.
- Sean Oliver
Thx for the heads up ... I placed an order, hope that this'll be a backup body for a d3x (or at least the d700) someday not-all-that-far-away ;-) Actually that sounds like a great combination for a lot of stuff - a solid full-frame with the right glass for the situation, and the d90 with that really handy nikon 18-200 to catch everything else.
- Bob Lozano
Video is cool, but don't know how much I'd really use it. I'm hoping the new 5D will have built in GPS / Geo tagging also.
- Jeff P. Henderson
FYI - D90 GPS is NOT included. The D90 is simply compatible with the GPS that Nikon will begin selling in November. This GPS is also compatible with the D200, D300, D700 and D3. Still looks like a cool camera.
- gfurry
Included GPS would be awesome. Really hoping that Canon comes up with something good.
- Jauder Ho
@jauderho I hope so too. Canon had an early lead in the prosumer DSLR market and just doesn't seem to be innovating as much lately. The 50D is just not compelling me to upgrade my 30D.
- Andy Denmark
The 5D coming out next month at photokina had better be damn good is all I can say. I'm planning on buying one so I'm hoping it will at least have geotagging capability.
- Thomas Hawk
Andy, well the 50D does have some nice improvements. But then again for me, I went from a 20D to a 5D because of the viewfinder and full frame. I still have the 20D and will probably get it converted to infrared at some point.
- Jauder Ho
In case anyone is looking for a deal and does not mind an older but still plenty good model. From Ken Rockwell's site, Ritz Camera is selling brand-new Canon 30D cameras on closeout for $699. http://twurl.nl/bryoys
- Jauder Ho
So I'm getting emails / blog comments / etc that I need to "fix our Facebook app". Thing is, we don't *have* a Facebook app. D'oh.

Home grown terrorists are the best. Foreign terrorists are stealing jobs from the hard working American terrorists. ;)

How many houses do you have in your house?
- Jason
Do I include the number of houses I had during the end of the last game of Monopoly or technically do you "lose" the houses if you put them back in the box?
- Philipp Lenssen
For different reasons than McCain, I also cannot answer this question. Is it my house if I rent? What if my company pays the rent? Can I count my main residence as a home even if it has a front desk and free breakfast buffet?
- Sarah Miller
The original question was how many houses he *owns*. That seems less ambiguous, though I guess you could still be uncertain about time shares and fractional ownership plans.
- ⓞnor
do you have a lot of timeshares?
- j1m
Sarah Miller might.
- ⓞnor
Sarah Miller is one of the few people I have known to be happy while living out of a hotel. I think it might be her superpower.
- Clare Dibble
To be fair, apparently it's his wife that owns all the property. Depending on their prenup, if he divorces he might not get any of that. If I were in that situation, I might not think I owned any houses either.

A link to cancel a comment with no hack! YAY!!!!

Mona, poster names are still links they're just styled differently so they don't look like the other links.

beta.friendfeed is my new friend !! lots of new stuff to play with.. 8-10hrs lag with list data ..but a very very powerful feature. !! Way to GO TEAM FF !!

The share button no longer appears in my feed. This is counterintuitive. Otherwise, it's been a great experience so far.

Where's the "me" tab? Everything else I LOVE!
- Jennifer Van Grove
Michael: if you're viewing your feed from the main address, there is a 'sharing' box up at the top, and the options (comment, photo, link) appear once you begin typing.
- FFing Enigma (aka Tina)
click on your name Jennifer, above right
- Tibor Holoda
@Jennifer "My Feed" in the sidebar replaces the "me" tab. And like Tibor said, your name works too.
- Dan Hsiao
you launch this right after takeoff from scoble to berlin - coinkydink? :)
- Allen Stern
@Stupid Blogger: Thanks, I'd figured that out, was just pointing out what seems like a bug in the current UI.
- Michael Nielsen
Looks nice on first glance, and it seems easier now to reach rooms. The friend lists should be a great way to organize my imaginary friends which are basically topic subscriptions. The "Add/ Remove friends" link is confusing at first because when you don't have any friends in the list yet, clicking it will result in nothing (making you wonder if it's broken). The message sharing post...

One word: wonderful.
- Brandon Titus
thanks for the iteration.. it's a great step forward
- Travis Parsons
like the new functions, but not the new layout, it just doesn't look like friendfeed and a bit feel like google groups (caused by the side bar maybe). miss the old layout...

It is kind of cool!
- Steve Chou
great design!!
- Ricardo J. Valle
on minor thing: on the main page, Post button and "Show best of: day - week" overlaps if you narrow the browser window.
- Dennis Seah
Fantastic!
- Mohamed J
We need a "remove from home feed" button under the friends settings. Or there must be an option that we can choose the list which shows on main page. For example, i want to see only "Professional" friends' feeds on the main page.

At last, I will be able to add to my feed all the people who subscribe to me, and it won't impact on my main source of infobrainment. It looks nice, too. Looks like you guys have pulled another one out of the bag. +1

I'm truly amazed at how good the UI is. The subtle touches like the use of blue links in just the right places or the contextual help like "How does hiding work?". Really great job. I think mioNews just became a little less useful to me, since FF now natively has friend groups. Oh well :P
- Patrick Lightbody
please have an option to set font size!
- h1ro
It has a great feature in allowing me to separate different people into different lists - that will be worth the whole interface change in itself. I hope that rooms also have embeddable feeds tho!
