Small houses challenge our notions of need as well as minimum-size standards

Down a rambling residential road on the outskirts of Sebastopol, the dream house sits like a testament to discriminating taste.

This dream house is the love child of artist-builder Jay Shafer, who lovingly hand-crafted it. The stainless-steel kitchen, gleaming next to the natural wood interior, is outfitted with customized storage and built-ins. From his bed, Shafer can gaze into the Northern California sky through a cathedral window. In his immaculate office space, a laptop sits alongside rows of architectural books and magazines -- many featuring his house on the cover. And from the old-fashioned front porch, he can look out on a breathtaking setting: an apple orchard in full bloom.

But in an era when bigger is taken as a synonym for better, calling Shafer's home a dream house might strike some as an oxymoron. Why? The entire house, including sleeping loft, measures only 96 square feet -- smaller than many people's bathrooms. But Jay Shafer's dream isn't of a lifestyle writ large but of one carefully created and then writ tiny.

Shafer, the founder of Tumbleweed Tiny Houses, began his love affair with diminutive dwellings about 10 years ago when teaching drawing at the University of Iowa in Iowa City. "I was living in an average-sized apartment and I realized I just didn't need so much space," he said. "I always envied people who had smaller homes, because they didn't have to do as much housework."

He bought an Airstream trailer, remodeled it and spent two years suffering the long, bitter winters before conceding that insulation was one amenity he was unwilling to forgo. "So I started from scratch and built myself a small house," he told me. He built the 100-square-foot home on wheels and parked it on a friend's farm outside of Iowa City. Eventually, he moved back into town but not without some difficulty. "I wasn't allowed to put the house on a city lot, because it was too small," he explained, referring to the minimum-size standards in the codes of many cities and counties across the country. So he bought a house, put his little house in the backyard and rented out the main house.

By 2000, he had decided this would be a way to channel his artwork, feed his hunger for simplicity and escape the rental rat race. After a friend asked him to build a house for him to live in, Shafer launched Tumbleweed Tiny House Co. in 2000. The friend went on to become the president of the Small House Society -- and thus was written one more episode of the small-is-beautiful movement. Shafer began building and designing little houses for people who wanted them as backyard retreats, second homes or primary residences. Eventually, he sold his own first home because he wanted something smaller and then built himself a 70-square-foot home on wheels (now called the XS House on his Web site).

"I knew I was going to be traveling out here and didn't know where I was going to put my house," he explained. "I wanted for it to fit in a parking place -- actually, I wanted to be able to parallel-park it."

I'd heard of getting a car small enough to parallel-park -- but a house?

Shafer pulled his house out West on a U-Haul and parked it in a public lot smack in the center of Sebastopol, hoping he would meet people sympathetic to the pursuit of the simple life and invite him to live on their property. It took exactly 20 minutes. For the next six months, Shafer lived on 40 acres of land with a creek outside the upscale town of Occidental. He then moved closer to Sebastopol, before selling his home to build his current one -- which he dragged to its current location in an apple orchard.

Over the years, he has built and sold 10 homes and dozens of house plans, which cost about $1,000. But the real story is that he's become a poster boy for simple living, with interviews or mentions in This Old House magazine, the New York Times, USA Today, the Wall Street Journal, the Los Angeles Times and, last February, even on "Oprah." What's behind the rush to peek inside Shafer's tiny living room and grill him about his lifestyle?

"Our society's been based on excess for so long, it's still a somewhat novel idea to live simply," he said. At 42, Shafer has a quiet, boyish presence and the unclouded brow of a man content with his choices. But he's also someone who obviously has gone to great lengths to live life according to his own principles -- an intensity seems to flicker in his eyes and in the humility of his explanations. You won't find much in the way of ranting about greed and gluttony. Though he does sometimes utter words like "excess," he maintains it's not for him to judge the needs of others.

"I can't say what the definition of a small house is," he said. "Maybe it's 4,000 square feet, if that's what it takes to suit their needs. The idea is that the house is being well-used. Some people need more space than others." Even when asked about the likes of Larry Ellison (whose recent building plans involve battling for a house bigger than a city block), Shafer resisted: "I don't know his needs."

Shafer said that small-house fans tend to be a nonjudgmental lot because so many have experienced "discrimination": Most building codes across the nation maintain a minimum-size requirement that prohibits the building of very small houses like Shafer's. Some homeowners associations and towns maintain this high standard in order to maintain high property values -- as well as keep out the affordable-housing riffraff. This has meant that many tiny-house aficionados only live their dream by skirting the law, living in someone else's backyard or heading for a rural county with no planning department.

But even in counties where tiny houses are allowed, lenders don't always look kindly on homes the size of a walk-in closet. Indeed, Shafer knows that some people might even see his house as a threat to their property values: That was an argument he heard often from his father, who recently sold his 4,000-square-foot suburban home in Mission Viejo to move into an RV. Now, Shafer thinks his father may be coming around to understanding the inherent beauty of living small.

Shafer chose Sebastopol in part because he thinks the politically liberal community will be supportive of abolishing minimum-size standards. His next dream is to create a little community of small houses, with a half-dozen or more connected by walking paths on a small piece of land.

"Trailer parks get a bad rap because they are made of cheap materials, but their structure is very conducive to community," he said. "Everyone knows high density is the way to go." Indeed, the tiny house may be the antidote to vertical high density in small towns and rural areas where neighborhoods are eager to preserve views and open space. Unlike in a three-story, lot-covering, mixed-use development, from a cluster of tiny houses, you can still smell the apple blossoms.

The Tabbed Breadcrumb Navigation

tabbed_breadcrumb_header.jpg

Typically when a site is architected with a structure that is both deep and wide, we look to elements like secondary and tertiary navigation and/or traditional breadcrumbs to help a user navigate. They’ve been around a long time and are now considered “best practices” by convention. rogers.jpg

Is a traditional 3+ layered navigation system really the “best” way to design a site whose structure has breadth and depth? We’re not so sure. One of the drawbacks of these methods is the fact that they can require quite a bit of visual overhead. We commonly see them take the form of sidebars with expanding and collapsing navigation. This not only eliminates space for page level content but the number of simultaneous navigation links they present can often make it visually and mentally overwhelming to decipher (see for yourself in the Rogers example).

Recently, we came across a new navigational system on some Yahoo properties like Food and TV then later on Marketwatch. The homepage navigation looks pretty standard. It’s when you dive deeper into the site that things begin to change. The navigation becomes focussed on whatever section you’re in and all of the parent sections become part of an integrated breadcrumb. The first level of navigation is held within a dropdown on the home tab. For conversation sake we’re calling this tabbed breadcrumbs.

We were immediatly intrigued by how natural this navigation system felt. It just seemed to get out of the way and provide a high level of focus on the section we were in. No matter how deep we dove, we never felt lost nor abstracted from the top-most navigation tier.

tabbed_breadcrumb.jpg

While we don’t think this type of navigation is right for every site, it is worth a look for those that need to go deep. A huge factor at this point that we honestly haven’t spent much time thinking about is how usable it is to the masses – will others find it as natural? Do you? The screenshots here don’t really do it justice – you really need to experience it first hand.

Bookmark Bliss: 10 Tools to help you select a Web 2.0 Color Palette

Well, another day and another entry in our Bookmark Bliss series here at Fuzzy Future. I’ll be the first to admit that when it comes to designing any interface my biggest roadblock has to be deciding on a color scheme. Whether it be a standalone application or a new web layout, I could come up with the best interface design but no one would care if the color scheme is an assault on the senses.

Lucky for me, there are a lot of helpful tools that can turn color coordination nightmares into a dream come true :) If you’re in the same boat as I am, have a look at some of these sites I unearthed from my bookmarks:

ColourLovers

EasyRGB

ColorBlender

ColorJack

Steel Dolphin Color Scheme Tool

DeGraeve.com Color Palette from Image Generator

Color Schemer

Kuler

Daily Color Scheme

Colr.org

The list is not too long, but really, how many different color resources do you need? My personal favorites are ColourLovers, EasyRGB, and Kuler. I really like the sites that allow people to submit their own color schemes and put together really comprehensive sets that include 5-10 different matching colors. These type of sites make it really easy to quickly choose one you like and incorporate it into your design immediately.

Have you found this list useful? If so, show your support by subscribing to our news feed. We’ve posted several other entries in our Bookmark Bliss series that you might find interesting as well…

The Great Tennessee Marijuana Cave

Law enforcement officers in Tennessee make the greatest underground discovery since Tutankhamen’s tomb was unearthed in the Valley of the Kings.

How to Use English Punctuation Correctly

Would you like to write a great paper for one of your classes? Maybe you need to submit a polished, impeccable proposal to your boss? If so, it will help to know proper usage of punctuation. The following is a list of common English punctuation marks and their usage.

Steps

  1. End your sentences with a period (full stop), question mark, or exclamation point (exclamation mark or shout mark).
    • Use the period (full stop) to denote a full stop at the end of a statement. The period ( . ) is one of the most commonly used punctuation marks.
      • The accessibility of the computer has increased tremendously over the past several years.
    • The question mark ( ? ), used at the end of a sentence, suggests an interrogatory remark or inquiry.
      • What has humanity done about the growing concern of global warming?
    • The exclamation point (exclamation mark, shout mark)( ! ) suggests excitement or emphasis in a sentence.
      • I can't believe how difficult the exam was!
  2. Use the semicolon and colon properly.
    • The semicolon ( ; ) has a few uses.
      • Use a semicolon to separate two related but independent clauses. Note that, if the two clauses are very wordy or complex, it is better to use a period instead.
        • People continue to worry about the future; our failure to conserve resources has put the world at risk.
      • Use a semicolon to separate a complex series of items, especially those that contain commas.
        • I went to the show with Jake, my close friend; his friend, Jane; and her best friend, Jenna.
    • The colon ( : ) has multiple uses.
      • Use the colon to introduce a list. Be careful not to use a colon when denoting a regular series. Usually, the word following suggests the use of a colon. Use only after a noun.
        • The professor has given me three options: to retake the exam, to accept the extra credit assignment, or to fail the class.
        • INCORRECT - The Easter basket contained: Easter eggs, chocolate rabbits, and other candy.
  3. Understand the differences between a hyphen and a dash.
    • The hyphen ( - ) was once a common punctuation mark on typewriters, when a long word might have been split between two lines. The hyphen is still used in a number of other areas:
      • Use a hyphen when adding a prefix to some words. The purpose of this hyphen is to make the word easier to read. If you were to leave the hyphen out of a word like re-examine, it would be reexamine, which would be harder to read. Understand that some words do not require a hyphen to separate the prefix from the word, such as restate, pretest, and undo. Let a dictionary be your guide for when to use the hyphen after a prefix.
        • Cara is his ex-girlfriend.
      • Use hyphens when creating compound words from separate words.
        • The up-to-date newspaper reporters were quick to jump on the latest scandal.
      • Use a hyphen when writing numbers out as words. Separate the two words of any number under one hundred with a hyphen.
        • There are fifty-two playing cards in a deck. ("The amount is one hundred and eighty." No hyphen is needed.)
            • Be careful with spelling out numbers above one hundred—if the number is used as an adjective, it is completely hyphenated, since all compound adjectives are hyphenated (I have one-hundred tapes). Otherwise, a hyphen should only occur if a number <100 occurs within the larger number, e.g., He lived to be one hundred twenty-one. Note that an "and" may often be used after "hundred."
    • The dash ( -- or ) should be used when making a brief interruption within a statement, a sudden change of thought, an additional comment, or a dramatic qualification. It can also be used to add a parenthetical statement, such as for further clarification, but should still be relevant to the sentence. Otherwise, use parentheses. Keep in mind that the rest of the sentence should still flow naturally. Try to remove the statement within the dash from the sentence; if the sentence appears disjointed or does not make sense, then you may need to revise. There should be spaces before and after the dash in British English.
      • An introductory clause is a brief phrase that comesyes, you guessed itat the beginning of a sentence.
      • This is the end of our sentenceor so we thought.
  4. Use the double quotation mark and single quotation mark/apostrophe for different purposes.
    • The double quotation ( " ) encloses a direct quotation, whether made by a person or taken from a piece of literature.
      • "I can't wait to see him perform!" John exclaimed.
      • According to the article, the value of the dollar in developing nations is "strongly influenced by its aesthetic value, rather than its face value."
    • The single quotation mark or apostrophe ( ' ) has a variety of uses.
      • Use the apostrophe together with the letter s to indicate possession. Be aware of the difference in using an apostrophe with singular or plural nouns. A singular noun will use 's, whereas the plural version of that singular noun will use s'. Also, be mindful of nouns that are always considered to be plural, such as children and people — here, you should use 's. Be aware of words that are possessive by nature and do not require apostrophes, such as hers and its (it's is used only for the contraction of it is). Their is possessive without apostrophe or s, except as a predicate adjective, where it becomes theirs.
        • The hamster's water tube needs to be refilled.
          • A singular noun with possession.
        • In the pet store, the hamsters' bedding needed to be changed.
          • A pluralized singular noun with possession.
        • These children's test scores are the highest in the nation.
          • A plural noun with possession.
      • Use the apostrophe to combine some basic subject-verb statements into a contraction. For example, cannot becomes can't, you are becomes you're, and they have becomes they've.
      • Use the single quotation mark within a regular quotation to indicate a quotation within a quotation.
        • Ali said, "Anna told me, 'I wasn't sure if you wanted to come!'"
      • Note that an apostrophe is not used with 's' to make a plural noun from a singular. This is a very common mistake and should be avoided.
        • CORRECT - apple → apples
        • INCORRECT - apple → apple's
  5. Indicate a break or pause within a sentence with the comma ( , ). This is another commonly used punctuation mark. There are several instances where you might use a comma:
    • Use the comma when denoting an appositive, or a break within a sentence that supplements and adds information to the subject.
      • Bill Gates, CEO of Microsoft, is the developer of the operating system known as Windows.
    • Use the comma when denoting a series. This is a set of three or more "list" items within a sentence. To save space in newspapers, some writers may omit the last comma.
      • The fruit basket contained apples, bananas, and oranges.
      • The computer store was filled with video games, computer hardware and other electronic paraphernalia.
    • Use a comma if your subject has two or more adjectives describing it. This is somewhat similar to a series, except that it is incorrect to place a comma after the final adjective.
      • INCORRECT - The powerful, resonating, sound caught our attention.
      • CORRECT - The powerful, resonating sound caught our attention.
    • Use a comma when referring to a city and state. It is also necessary to use a comma to separate the city and state from the rest of the sentence.
      • I am originally from Freehold, NJ.
      • Los Angeles, CA, is one of the largest cities in the United States.
    • Use a comma to separate an introductory phrase (which is usually one or more prepositional phrases) from the rest of the sentence. An introductory phrase briefly introduces the sentence, but is not part of the sentence's subject or predicate, and it therefore should be separated from the main clause by a comma.
      • After the show, John and I went out to dinner.
      • On the back of my couch, my cat's claws have slowly been carving a large hole.
    • Use the comma to separate two independent clauses. Having two independent clauses in a sentence simply means that you can split the sentence into two. If your sentence contains two independent clauses that are separated by a conjunction (such as and, as, but, for, nor, so, or yet ), place a comma before the conjunction.
      • Ryan went to the beach yesterday, but he forgot his sunscreen.
      • Water bills usually rise during the summer, as people are thirstier during hot and humid days.
    • Use a comma when making a direct address. When calling one's attention by name, separate the person's name and the rest of the statement with a comma. Note that this kind of comma is used rarely in writing, because this is something that we do normally while speaking.
      • Amber, could you come here for a moment?
    • Use a comma to separate direct quotations. A comma should come after the last word before a quotation that is being introduced. It is not necessary to use a comma in an indirect quote. A comma is usually not necessary if you are not quoting an entire statement.
      • While I was at his house, John asked me if I wanted anything to eat.
        • An indirect quotation that does not require a comma.
      • While I was at his house, John asked, "Do you want anything to eat?"
        • A direct quotation.
      • According to the client, the lawyer was "lazy and incompetent."
        • A partial direct quotation that does not require a comma.
  6. Understand the difference between parentheses, brackets, and braces.
    • Use parentheses ( ( ) ) to clarify, to place an afterthought, or to add a personal comment. Be sure to include the period after the closing parenthesis.
      • Steve Case (AOL's former CEO) resigned from the Time-Warner board of directors in 2005.
        • Used for clarification. Here, commas can replace the parentheses.
      • You will need a flashlight for the camping trip (don't forget the batteries!).
        • An afterthought. Note that the period (full stop) follows the last parentheses — not before the first. Also note that replacing the parentheses with a comma may not be entirely suitable here, and is better off with a period or a semicolon. And that if the parenthetical thought is an "independent" one, perhaps it should be a sentence in itself. In the above example: "...the camping trip. (Don't forget the batteries!)"
      • Most grammarians believe that parentheses and commas are always interchangeable. (I disagree.)
        • A personal comment.
    • Use brackets ( [ ] ) to signify an editor's note in a regular piece of writing. You can also use brackets to clarify or to revise a direct quote so that it appeals to your own writing. Brackets are often used to encompass the word "sic" (Latin for thus), suggesting that the previous word or phrase was written "as is", with the error intended to be displayed.
      • "[The blast] was absolutely devastating", said Susan Smith, a local bystander at the scene of the incident.
        • "It was absolutely devastating!" – the actual quote by Susan Smith.
      • The English professor's report read, "Their [sic] are too many problems in are [sic] department."
    • Braces ( { } ) are most widely used in denoting a numeric set in mathematics. Though generally uncommon, braces can also be used in regular writing to indicate a set of equal, independent choices.
      • { 1, 2, 5, 10, 20 }
      • Choose your favorite utensil { fork, knife, spoon } and bring it to me.

Tips

  • If you write in a professional capacity, be sure to follow any guidelines or style guides provided by your employer. In some cases, their rules can be at odds with what you read here or elsewhere, but their rules always take precedence. For example, some companies use serial commas (a, b, and c) and others do not (a, b and c).
  • Many grammar experts believe that parentheses and commas are often interchangeable when setting off information. While this is sometimes true, there are some cases where a set of parentheses might be more suitable, such as in indicating one's personal thought.
  • Although dashes and parentheses have similar uses, remember that parentheses indicate a stronger "side notion" than dashes.
  • There are exceptions to the hyphen-dash rule. In making compound words, when one of the words is itself composed of two words, use an en dash ( – ) rather than a hyphen, as in, "He took the Paris–New York route." En dashes are also used between numbers, as in page numbers or years, to denote a range. ("A discussion on personal finance is found in pages 45–62.")
  • The placement of punctuation marks before or after a closing quotation mark varies. American English leaves the punctuation mark inside the quotation if it is part of the quotation, "like so." (Commas and periods (full stops) are always put inside the quotation marks for a sentence in American English, regardless of whether the quotation has punctuation at the end. Other types of punctuation marks are put outside the quotation if they are not part of the quotation.) British English tends to leave the punctuation mark outside the quotation, "like so".
    • At times, British English will switch back and forth between the inside and outside, depending on the context. For example, interrogative quotations may keep the question mark inside the quotation, as in, "Do you like this question?"
  • In formal writing, try to avoid excessive use of question marks and exclamation points. Most of your sentences should be declarative statements.
  • Dashes are usually considered to be informal. You might want to replace the use of a dash with a set of parentheses, or even commas. Similarly, limit the frequency of dash use in your writing; they should be reserved to emphasize a couple of important points.
  • If you decide against the serial comma in your work, make sure that the meaning of the sentence can stand without its use. Think about the classic example of a sentence in which the serial comma is needed: "My heroes are my parents, Mother Teresa and the Pope."
  • If you find that a sentence seems to drag on, find a way to add a comma or two, so that it is easier on the reader's eyes. If a sentence becomes too long, then consider splitting it into two or more sentences.
  • Never be afraid to have short sentences in your writing by splitting up long sentences that contain several points. Your reader will appreciate writing that is clear and concise with briefer statements, as opposed to a one-page paragraph with twenty words per sentence.

Warnings

  • The ability to use English punctuation appropriately may help your writing to flow much more smoothly, generally creating a more "intelligent" appearance. Don't overdo it by adding punctuation when it is inappropriate!

The Future of RSS

Written by Alex Iskold / April 03, 2007

There is little doubt that RSS is a disruptive, game-changing technology. The so called Really Simple Syndication (previously also called Rich Site Summary and RDF Site Summary), has powered a fundamentally new way to deliver and consume web content. Before RSS, users had to visit individual web sites to find out what was new. Today, news is delivered via RSS directly to web browsers, desktops and aggregators. With RSS, the dynamics of the web changed into an on-demand medium.

RSS usage has since spread beyond simple news delivery. Companies like de.licio.us, Flickr and YouTube added another dimension to RSS - i.e. they made it an integral part of the Social Web (social networking, photos, video, etc). Also Google built Google Base, its Craigslist competitor, entirely on RSS. Other companies too are beginning to extend RSS, sometimes with proprietary extensions.

In short, because of RSS ubiquity it is now a very attractive delivery medium for all kinds of content. However because the basic format is simple and primitive, there is no way to encode semantics without building an extension. So in this post, we look at RSS today and ask if RSS is evolving into a tool for delivering complex, semantically rich information.

Brief History of RSS

RSS is an XML-based language and its early roots can be traced to back to 1995, to Apple Labs and then slightly later to Netscape, Userland Software and Microsoft. The first major use of RSS was in 1999 when it was integrated into the My Netscape portal. So RSS is not a new kid on the block, in fact it was around way before the new Social Web came about. So why did it not take off earlier? It appears to have been misunderstood and de-emphasized by AOL, and was downplayed after the Netscape acquisition.

RSS survived mainly because of one man's heavy-lifting - Dave Winer. Dave authored RSS 0.91, RSS 0.92 and then the widely used RSS 2.0 specification. Over the years he has drummed the beat of RSS on his blog and every corner of the web, until it got adopted by companies such as Microsoft and Yahoo. [Ed: there were also heated format wars during this time, with RSS 1.0 and then ATOM, but we won't re-hash those here!]

RSS in a Nutshell

RSS is rather simple language to describe the latest headlines (or the full content of articles). The following explanation of RSS is based on the RSS 2.0 format, but other formats are similar. Here is a sample of what it looks like:

Each RSS file consists of items delivered in a single channel. Each item has a title, a link and a description (attributes). The on-demand aspect of RSS is enabled by two timestamps - the lastBuildDate in the channel indicates the last time this channel changed, while the pubDate of the item indicates when the item was published. RSS aggregators (a.k.a. RSS readers) take advantage of these timestamps to decide when new content is available.

The old web was a pure pull medium, because users had to visit each web site in order to find out what (if anything) had changed. However, businesses and advertisers in particular love push technologies - where content is delivered to the user when it becomes available. RSS is an interesting mix between the two extremes, neither of which could actually work in our information-overloaded and advertising-saturated world. RSS is basically a filtered push - the user subscribes (pulls in) to channels that he/she likes, and after that content is delivered automatically.

RSS - Beyond the Distribution Medium

So today RSS is a great distribution medium. Why? Because it has become ubiquitous. If you are an online business with customers and you do not utilize RSS, then you are simply missing out. Smart companies are leveraging blogs, photos, video, podcasts to stay in touch with customers daily. Other services, like del.icio.us (owned by Yahoo), allow users to publish and subscribe to feeds, enabling powerful social networks outside the website.

The ubiquity of RSS is so powerful that publishers want to deliver more and more content to users via RSS. But the problem is that basic RSS cannot be used to deliver structured information.

Lets look at a specific example. Suppose your bank wants to deliver you statements in RSS instead of email. However if you use RSS as it is today, then the bank statements would need to be encoded in HTML - meaning no financial application would be able to manipulate the data. When your Quicken software connects to the bank, the information gets downloaded in a structured format. But with RSS, it is simply not possible currently - because there is no way to describe bank transactions using standard RSS.

Why this matters

At first glance this might not make much sense. Why do we care about RSS having structure? Because structured RSS holds the promise of information portability. Going back to the bank statement example, it would be great if the statement also can be taken as an input by a financial application of your choice. Since we are moving our desktops online - e.g. the trend of Web Office suites - the formats that we used in the Windows age are not going to work well. We need something lighter and more portable to carry our information around - hence XML and RSS. 

Note that businesses are probably the most interested party here, because to a business a loss of structure leads to loss of meaning, loss of trail and ultimately the loss of customers.

Extending RSS

To extend RSS basically means to add a custom tag. For example, Google Base currently has 148 attributes that it recommends to add to RSS. Here are some examples starting with the letter 'a': age, actor, agent, apparel type, artist. These are everyday concepts that might come handy in classifieds and other aspects of life. All of these tags allow Google Base to make RSS structured, whilst preserving its basic capability. 

Similarly, FeedBurner inserts proprietary attributes into their RSS feeds. This is done purely for house keeping purposes, because only FeedBurner's engine is meant to process these attributes.

The main problem with extending RSS is agreeing on what things mean. In the case of FeedBurner it is not critical, but in the case of Google Base it is much more important. In order for RSS extensions to work, the second piece of the old technology dilemma needs to be solved. There needs to be a common format for communicating data between applications:

Conclusion

Purists, myself included, would argue that using RSS for the delivery of complex content is a hack. After all, what does a news format have to do with semantics? But technologies do not evolve in a pure way. Some things catch on and succeed, and become widely adopted. The fact is that RSS is becoming a pervasive on-demand technology, which outweighs the fact that it was never meant to be the semantic agent of the web. But even from a purist's perspective, there may not be much to pick at - RSS is just another XML-language and in that respect it is as good as any other flavor of XML.

So will RSS become more than it is today? Will it be able to solve the second piece of the old technology industry puzzle - the common format? As usual, only time will tell. However RSS does look like a strong front runner at this point, as we do not have a lot of attractive, simple and widespread alternatives. But again, who knows, technology is not a predictable thing. 

Do you think RSS will expand beyond what it is today? What real world things are you are seeing that hint at RSS being used in more ways?

The Digg Crew

The much anticipated interview with various members of the Digg staff team is finally here! We thank the ever busy development team for taking the time to give us some responses.

Q: What’s the best part of working for a young company? Is it the same as an everyday job, or is it more fun to be part of such a highly successful site?

Digg

The Digg team is still relatively small, but we are completely focused on developing new features for our users..and yes, it’s a blast to work for a company like Digg because we have such a loyal following and close relationship with the community.

Q: On a hosting / tech specs related question, how do you estimate or determine the amount of bandwidth you’ll need each month to run such a high traffic site?

We grew fairly quickly right out of the gate, so before too long one server became two servers, myisam become innodb, we moved to Debian then we went to three servers, Apache 2.x, mysql master-slave replication, started using memcached, moved to PHP 5.x, hired a dba. And then the pace picked up yet again. We try to account for 1,000 requests per second at high points in the day for traffic.

The Digg Team

Q: How likely is it that you will be going strong and still run by the same people in the next 5 - 10 years? Is selling to another company something that you see in the near future?

We just recently closed a 2nd round of funding, and are completely devoted to focusing on growing the site internally into something that will continue to offer users the best social experience on the Net.

Digg, at its current design state (April 2007)

Q: What’s it like knowing that everything you do front-end wise is going to have both positive and negative feedback from the hardcore users? Do you take a lot of the feature and design suggestions to heart?

We always listen to the users, and check every email that comes to the feedback address. It might take some time for us to get everything that’s requested rolled out, but that’s because we want to do it right.

Q: How long will it be before the Digg API is released?

Soon, very soon.

Q: Are there any plans for allowing users to register as “owners” of a particular URL (similar to how a user can register as the owner of a blog at technorati) and to allow them to “adjust” poorly chosen (or sometimes blatantly false) titles and descriptions that link to their content?

We don’t have any plans along those lines at this time, but I would add that Digg currently provides users with a variety of tools to report inaccurate content on the site. With these tools, Digg empowers its more than one million users as editors of content on the site.

Q: Care to shed some light on any future plans and what we should be looking out for from Digg in the coming months / year?

Stay tuned. As always, Digg will continue to innovate and offer cool new features. Also, please come out to the Digg user celebration party at Mezzanine in San Francisco on April 19th.

The Male Brain vs The Female Brain

Some interesting differences between men's and women's brains, collected from sources listed below. Read with a grain of salt, and further investigate the ones that get you riled up.


1. Men's brains are larger, but as they age, they also shrink faster than women's brains.

2. Women's brains operate at a higher temperature, due to burning more glucose.

3. Women use more of their brains when they think.

4. Men's brains contain roughly 6.5 times the amount of grey matter related to general intelligence as women's brains, while women's brains contain about 10 times as much white matter related to general intelligence as men's. Researchers point to this finding to explain the controversial belief that in general, men may naturally excel at math while women tend to excel in areas like language. Read more about this research here.

5. Men tend to score an average of 4 to 5 points higher on intelligence tests, as reported by the journal Intelligence in Sept. 2006. Don't believe us? Click here.

6. The average man will think about sex as often as once a minute, while the average woman will think of sex much less often, as infrequently as once every one or two days.

7. Why do women always want to talk? Researchers have found that connecting with another through talking will trigger the pleasure centers in a woman's brain, a high second only to an orgasm.

8. Baby girls have been observed to typically have stronger reactions than boys to disturbing or distressful sounds.

9. A 20-second hug will trigger the release of oxytocin in a woman's brain. The effect of this chemical will often give the woman a feeling of trust in the person hugging her.

10. Men reportedly use fewer words per day than women. Depending on which study you believe (if any), the "word gap" can be anywhere from 1,000 to 10,000 words a day.
