Dennis Ritchie on C and UNIX

Dennis Ritchie, designer of the C programming language, and co-inventor of UNIX — arguably two of the most influential computer science creations ever — passed away at 70.  As my formative years in computing were highlighted by UNIX and C, I felt a bit of nostalgia as well as gratitude for “dmr”s contributions.  I still think of the original K&R as the best programming book ever – when a colleague told me he was going to write a book on C, I couldn’t understand why – since K&R existed, nothing else need be said!  In fact its conciseness greatly influenced my own writing style – some might say to a fault.  Years later, I used the first edition K&R as guidance for the original DMTF DMI 1.0 spec (sadly, no longer available), which was somewhat ironic that I’d use it for a standards committee document:

When I read commentary about suggestions for where C should go, I often think back and give thanks that it wasn’t developed under the advice of a worldwide crowd.
— Dennis Ritchie

Tonight I spent quite a bit of time reading sections of his Bell Lab’s home page — technical materials and observations that I hope stays up for posterity.  These are important artifacts that brought us to where we are now.

From an operating system research point of view, Unix is — if not dead — certainly old stuff, and it’s clear that people should be looking beyond it.

— Dennis Ritchie, 1990 Summer Usenix keynote speech

UNIX, if you don’t know, is the basis for the software that runs Mac OS X, Linux, Android, iPhones & iPads, and lots of other stuff.  Not too shabby.

What comes next after Insanely Great?

I don’t have any personal stories to tell about meeting Steve Jobs.

I’m not a “long-time” Apple user.  But I am acutely aware of the date I would become one: January 7, 2003.  Steve Jobs introduced the 12″ Aluminum PowerBook G4 at MacWorld.  I’m not sure how I knew about the keynote – perhaps because I had an iPod and thought it was great – but that afternoon I found myself watching the QuickTime replay from Apple’s web site, hunched over some Windows laptop.  I’d never seen a SteveNote before, and was hooked by everything about it, and I said “I am switching to the Mac.”  Keep in mind I hadn’t even used one at the time, but I still knew it.

Long story short, while diving into Apple’s worldview can be daunting, it’s been incredibly rewarding.  I’ve learned a lot about how difficult it is to make something appear simple.  I started thinking about software in words like elegance, and started using the word design to mean more than architecture.

The iPod and the PowerBook have long since been retired, obsoleted by newer models.  But I still have them, because they were my first.

Rest in Peace, Steve Jobs.

iPhone Sales Tax is on the Unsubsidized Price

So the iPhone 3G S is lust-worthy, if for no other reason than the 3MP autofocus camera and the speed increase. There’s plenty of news about how AT&T is lagging – no MMS (coming), no tethering (maybe coming), giving smaller discounts to iPhone 3G customers than to new customers.

I’m not eligible for the $299 price because I’ve given Apple too much business, thus AT&T has had to subsidize me twice (read: I bought an original iPhone and a year later bought an iPhone 3G). So I get the option to wait until October to get the $299 price, or pay $499 now. I’ll wait, thanks. Maybe for whatever Apple announces next summer.

But Heidi never upgraded to the iPhone 3G, so she’s eligible for the $299 price. Great, let’s put that puppy in the cart. Whoa, look at the tax!

AT&T iPhone tax

Yep, the tax is calculated as 9.5% (welcome to California) on the full $699 retail price of the phone. AT&T doesn’t subsidize that, and I couldn’t find it disclosed anywhere. I asked the Apple Store live chat — they were useless (told me the tax was on the $499 price) until I (duh) backed into the number on my own.

So, Apple’s ads should say the 32GB iPhone costs $699, minus an “instant rebate” that depends on how much AT&T has already subsidized you. But giving the real price wouldn’t sound as lust-worthy, would it?

Update July 18:At the online Apple Store, there’s small print at the bottom of the buy iPhone page that says

In CA, MA, and RI, sales tax is collected on the unbundled price of iPhone.

The CA regulation that requires Apple to collect this tax is documented at What Apple doing isn’t illegal — just a bit misleading.

Yahoo! acquires IndexTools

iPhone in Hungary
Today Yahoo! and IndexTools announced that Yahoo! is acquiring IndexTools. Here is the official press release.

I’m really jazzed about it. IndexTools is a great group that’s been laser focused on the stuff that customers care about. They have a very practical attitude towards their products. Because they started in 2000, they learned from the pioneers, and built a deep analytics system that really works well. That much was clear as soon as we popped the hood and poked around inside .. unlike a lot of their competition, they didn’t have an old and a new product that they bolted together.

So does this mean we’re going to do “Yahoo! Analytics”, and try to “steal” web sites away from Google Analytics or the commercial web analytics vendors? See, that’s not what this is about. Yahoo! has stated its desire to be a “partner of choice”, and as the new Yahoo! strategy began to sink in, it became clear that the new Yahoo! was going to need to offer a new level of products to its partners. We have many, many thousands of small and medium businesses partnering with us now, and we want to make sure they have the tools they need. We’ve already announced an open strategy where developers can take advantage of Yahoo! products and services; we want to make sure they get the analytics they need too. Yahoo! has so many partners in so many places that can benefit from this technology, it became clear — even obvious — it was now the right thing to do.

Yeah, we still have a team working on analytics solutions for our “owned and operated” world — Yahoo! is too big a customer for IndexTools, or any other commercial vendor for that matter. There’s a world of difference between massive scale for one huge customer, and massive scale for a huge number of small and medium-sized customers. Now we have both.

As for what this means for the web analytics industry, I’ll leave that to the pundits, analysts and fortune tellers.

Here’s some of the combined team after a day of meetings at IndexTools.

The Behavioral Targeting Penguin

Behavioral PenguinHi kids! Today the cute and cuddly Mr. Penguin from AOL will answer all your questions on behavioral targeting! Isn’t he cute! Now you know that behavioral targeting is your friend!

Have a good day! And a tip o’the cap to the Good People at AOL who keep Mr. Penguin in anchovies in return for a little education gig he does for them.

PS oh, and did you know that Google doesn’t track you around the web? Hahahahahahaha!

PPS Seriously, why doesn’t AOL focus on the benefits of BT — like that the ads you’ll get are actually relevant? I am also concerned that they are confusing BT with tracking across an ad network. They are not the same. As it is, what I see from the storyboard is I get a TRACKING COOKIE ON MY COMPUTER followed closely by somebody thinking “I should remove that cookie”… is BT the new cookie? Is the cookie the new cookie?

Twitter: Social Microblogging

TwitterI’ve been dorking with Twitter .. still trying to figure out if it’s a great waste of time, or a lousy waste of time. I’m sure the cool kids are using it via SMS, but something about having my phone buzz me to learn that one of my friends is now eating a cookie just doesn’t get me that excited. The web site seems to be the best place for browsing and discovery, but for plain ol’ status updating, I’m using Twitterific for a local Mac app that grabs updated tweets every so often. PC users might want to opt for TwitBox.

I dismissed Twitter when I first tried it, but later read that what I experienced was typical, and exploring a bit can lead to an appreciation for the nuances of the service. But it wasn’t until I read Jeffrey Walker’s two Twitter posts that I decided to take another look.

With a little web spelunking, there’s an interesting social web under Twitter. (e.g. Jenna Jameson is “friends” with Barack Obama and John Edwards) but from what I can tell, the definition of “friend” is pretty loose. The “six degrees” aspect isn’t being visualized yet, but that isn’t to say people aren’t trying various mashups: witness David Troy’s Twittervision and Twittermaps. For more, check out the Twitter Fan Wiki.

I can see a great use of Twitter: as a (non-human) status service. In this specific case, you can see BART service messages – useful if you need real-time status updates for the Bay Area Rapid Transit system. Another: Red Sox updates! Having Twitter as a micro multicast/social alert system (or heck, an emergency broadcast system) is a great idea – it’s faster than the typical way one uses RSS. To that end, I wonder what Bob Wyman thinks of this “publish/subscribe” system.

I know I started the post sounding skeptical, but the Twitter crew did the right thing by providing an API to the service. That means it’ll become a platform, and taken in directions the developers haven’t thought of yet. One of these may end up being a killer app.
