This really cracks me up. Every time i pull out a bag of beef jerky the same thing happens:

"Eww, what is that??"
"It's Beef Jerky."
"Are You Sure?"
"Yah, I made it.. You want some??"
"Uhh..."
"Come on, you'll like it"
Ok, Ok.
**Tries the Jerky**
"OMFG!! ITS SO GOOD"
"I Know"
"How do you make it??"
"Cut up steak, marinade it, and dehydrate it"
"What's a dehydrator??"
"It dries things"
"Give me another pice!!!"
"OK OK"
"I'Il buy the bag!"

Basically the last couple steps repeat every day as they come to me for their jerky needs. I am happy (i think) to say that everyone who's tried my beef jerky, is now addicted.

An then comes the final comment, as they stuff more jerky into their mouth: "You should seriously make this a business."
So I pondered and realized that at first, the business would be successful. I wouldn't even need much marketing, world of mouth would do the trick. But when you start to get orders out of your community, larger orders, you need to boost production. And thats were the problem lies.

When your business model is born, you need to make sure it can do one thing and one thing only, SCALE. Yeah, selling jerky to my friends will work, but when I go global, something happens. There is a correlation between more production and quality. In order to make the jerky faster to meet my demand i need to cut time, and the only thing that will end up doing is diminishing my homemade goodness and quality. That's why Slim Jim's taste like S#%&T (And aren't made of the Finest Beef you can get)

This is could be an awesome time saving tool for web site development and deployment... No more cutting / cropping / scaling. Sign me up!
Check out the video - very impressive, especially the object removal algorithm.

Interesting yet very brief interview on what the New York Times is doing with Hadoop. It's always fascinating to me to read about the tools and approaches people use with the level of scalability most of us don't have to worry about. Also interesting to me is the MapReduce functionality in Hadoop since it's the same idea used by CouchDB views, and I'm absolutely loving the bit of work I've been doing with CouchDB.

Database Sharding at Netlog, with MySQL and PHP

This article accompanies the slides from a presentation on database sharding. Sharding is a technique used for horizontal scaling of databases we are using at Netlog. If you're interested in high performance, scalability, MySQL, php, caching, partitioning, Sphinx, federation or Netlog, read on ...

This presentation was given at the second day of FOSDEM 2009 in Brussels. FOSDEM is an annual conference on open source software with about 5000 hackers. I was invited by Kris Buytaert and Lenz Grimmer to give a talk in the MySQL Dev Room. The talk was based on an earlier talk I gave at BarcampGent 2.

Doing research now about ESI / Varnish, and saw this useful explanation of the entire process. ESI looks like a pretty powerful weapon in the web scaling arsenal.

Why are we partitioning our dataset and how does it help us to achieve scalability of our application?

It is difficult, if not nearly impossible, to massively scale your data layer when the data is limited to residing on a single server. Whether the limiting factor is a hardware cost issue, or you’ve simply equipped your server with the highest performing hardware possible, we ultimately find ourselves up against a wall – there are inherent limitations to what is currently possible by vertical scaling our hardware, it is a simple matter of fact. If we instead take our dataset schema, duplicate it onto multiple servers (shards), and split (or partition) the data on the original single server into equal portions distributed amongst our new set of servers (shards), we can parallelize our query load across them. Adding more servers (shards) to our existing set of servers results in near limitless scalability potential. The theory behind how this works is simple, but the execution is a fair bit more complex thanks to a series of scale-specific issues one encounters along the way.

Great article, hat tip to Mike Montano from Backtype. We are both going through massive scale growing pains. Articles like this are like a balm for burn victims. ;-)

Here is a list of projects that could potentially replace a group of relational database shards. Some of these are much more than key-value stores, and aren’t suitable for low-latency data serving, but are interesting none-the-less.

Name Language Fault-tolerance Persistence Client Protocol Data model
Project Voldemort Java partitioned, replicated, read-repair Pluggable: BerkleyDB, Mysql Java API Structured / blob / text
Ringo Erlang partitioned, replicated, immutable Custom on-disk (append only log) HTTP blob
Scalaris Erlang partitioned, replicated, paxos In-memory only Erlang, Java, HTTP blob
Kai Erlang partitioned, replicated? On-disk Dets file Memcached blob
Dynomite Erlang partitioned, replicated Pluggable: couch, dets Custom ascii, Thrift blob
MemcacheDB C replication BerkleyDB Memcached blob
ThruDB C++ Replication Pluggable: BerkleyDB, Custom, Mysql, S3 Thrift Document oriented
CouchDB Erlang Replication, partitioning? Custom on-disk HTTP, json Document oriented (json)
Cassandra Java Replication, partitioning Custom on-disk Thrift Bigtable meets Dynamo
HBase Java Replication, partitioning Custom on-disk Custom API, Thrift, Rest Bigtable
Hypertable C++ Replication, partitioning Custom on-disk Thrift, other Bigtable

Awesome review of a bunch of possible Key-value store pairs. Tokyo Tyrant conspicuously missing.
