Ho John Lee's Weblog

These are my links for January 30th through February 4th:

• Op-Ed Contributor – Microsoft’s Creative Destruction – NYTimes.com – Unlike other companies, Microsoft never developed a true system for innovation. Some of my former colleagues argue that it actually developed a system to thwart innovation. Despite having one of the largest and best corporate laboratories in the world, and the luxury of not one but three chief technology officers, the company routinely manages to frustrate the efforts of its visionary thinkers.
• Leonardo da Vinci’s Resume Explains Why He’s The Renaissance Man For the Job – Davinci – Gizmodo – At one time in history, even da Vinci himself had to pen a resume to explain why he was a qualified applicant. Here's a translation of his letter to the Duke of Milan, delineating his many talents and abilities. "Most Illustrious Lord, Having now sufficiently considered the specimens of all those who proclaim themselves skilled contrivers of instruments of war, and that the invention and operation of the said instruments are nothing different from those in common use: I shall endeavor, without prejudice to any one else, to explain myself to your Excellency, showing your Lordship my secret, and then offering them to your best pleasure and approbation to work with effect at opportune moments on all those things which, in part, shall be briefly noted below..The document, written when da Vinci was 30, is actually more of a cover letter than a resume; he leaves out many of his artistic achievements and instead focuses on what he can provide for the Duke in technologies of war.
• jsMath: jsMath Home Page – The jsMath package provides a method of including mathematics in HTML pages that works across multiple browsers under Windows, Macintosh OS X, Linux and other flavors of unix. It overcomes a number of the shortcomings of the traditional method of using images to represent mathematics: jsMath uses native fonts, so they resize when you change the size of the text in your browser, they print at the full resolution of your printer, and you don't have to wait for dozens of images to be downloaded in order to see the mathematics in a web page. There are also advantages for web-page authors, as there is no need to preprocess your web pages to generate any images, and the mathematics is entered in TeX form, so it is easy to create and maintain your web pages. Although it works best with the TeX fonts installed, jsMath will fall back on a collection of image-based fonts (which can still be scaled or printed at high resolution) or unicode fonts when the TeX fonts are not available.
• Josh on the Web » Blog Archive » Abusing the Cache: Tracking Users without Cookies – To track a user I make use of three URLs: the container, which can be any website; a shim file, which contains a unique code; and a tracking page, which stores (and in this case displays) requests. The trick lies in making the browser cache the shim file indefinitely. When the file is requested for the first – and only – time a unique identifier is embedded in the page. The shim embeds the tracking page, passing it the unique ID every time it is loaded. See the source code.

  One neat thing about this method is that JavaScript is not strictly required. It is only used to pass the message and referrer to the tracker. It would probably be possible to replace the iframes with CSS and images to gain JS-free HTTP referrer logging but would lose the ability to store messages so easily.

• Panopticlick – Your browser fingerprint appears to be unique among the 342,943 tested so far.

  Currently, we estimate that your browser has a fingerprint that conveys at least 18.39 bits of identifying information.

  The measurements we used to obtain this result are listed below. You can read more about the methodology here, and about some defenses against fingerprinting here

• Benlog » Don’t Hash Secrets – If I tell you that SHA1(foo) is X, then it turns out in a lot of cases to be quite easy for you to determine what SHA1(foo || bar) is. You don’t need to know what foo is. because SHA1 is iterative and works block by block, if you know the hash of foo, then you can extend the computation to determine the hash of foo || bar

  That means that if you know SHA1(secret || message), you can compute SHA1(secret || message || ANYTHING), which is a valid signature for message || ANYTHING. So to break this system, you just need to see one signature from SuperAnnoyingPoke, then you can impersonate SuperAnnoyingPoke for lots of other messages.

  What you should be using is HMAC: Hash-function Message Authentication Code. You don’t need to know exactly how it works, just need to know that HMAC is specifically built for message authentication codes and the use case of SuperAnnoyingPoke/MyFace. Under the hood, what’s approximately going on is two hashes, with the secret combined after the first hash

• All Your Twitter Bot Needs Is Love – The bot’s name? Jason Thorton. He’s been humming along for months now, sending out over 1250 tweets to some 174 followers. His tweets, while not particularly creative, manage to be both believable and timely. And he’s powered by a single word: Love.

  Thorton is the creation of developer Ryan Merket, who built him as a side project in around three hours. Merket has just posted the code that powers him, and has also divulged how he made Thorton seem somewhat realistic: the bot looks for tweets with the word “love” in them and tweets them as its own.

• Building a Twitter Bot – "Meet Jason Thorton. To people who know Jason, he is a successful entrepreneur in San Francisco who tweets 4-5 times a day. But Jason has a secret, he’s not really a human, he’s the product of my simple algorithm in PHP

  Jason tweets A LOT about the word “love” – that’s because Jason actually steals tweets from the public timeline that contain the word “love” and posts them as his own

  Jason also @replies to people who use the word “love” in their tweets, and asks them random questions or says something arbitrary

  It took me about 3 hours to code Jason, imagine what a real engineer could do with real AI algorithms? Now realize that it’s already a reality. Sites like Twitter are full of side projects, company initiatives, spambots and AI robots. When the free flow of information becomes open, the amount of disinformation increases. Theres a real need for someone to vet the people we ‘meet’ on social sites – will be interesting to see how this market grows in the next year

"These new large datacenters are quite different from traditional hosting facilities of earlier times and cannot be viewed simply as a collection of co-located servers. Large portions of the hardware and software resources in these facilities must work in concert to efficiently deliver good levels of Internet service performance, something that can only be achieved by a holistic approach to their design and deployment. In other words, we must treat the datacenter itself as one massive warehouse-scale computer (WSC). We describe the architecture of WSCs, the main factors influencing their design, operation, and cost structure, and the characteristics of their software base."

This approach provides a tractable method to understand user activity on the web site and how this activity depends on web site design choices, especially the choice of what information about other users' behaviors is shown to each user. We illustrate this modeling approach in the context of user-created content on the news rating site Digg.

Spent some time at CloudConnect last week. “Cloud computing” has an increasing amount of buzz lately. I notice that India is the top region and Korean is the top language for searches on the topic. The top 3 cities are Bangalore, San Jose, and Seoul. That sounds consistent with my impression of levels of interest and activity. Infoworld says “Cloud Computing shapes up as big trend for 2009″. It’s certainly turning into a hot label, although the underlying internet service infrastructure ideas have been around for a long time.

The current business environment is characterized by high uncertainty. However, assuming the global economy doesn’t totally collapse, companies that successfully migrate IT activities to the cloud can achieve lower costs and flexible scale, at the potential cost of vendor lock-in, regulatory uncertainty, and the operational risk of the transition itself.

Some of this reminds me of the dynamics around corporate ERP projects a decade ago. If you were the incumbent leader in your market, you’ve already invested in your line-of-business IT infrastructure, and it’s working. You may have even been an early adopter of ERP technologies, gaining time and experience in pilot projects to develop a competitive advantage in your in-house IT. At some point the other competitors in a given market end up in a difficult position – either continue as they are with a strategic disadvantage (no ERP), or take on a risky overhaul of their core IT systems and business processes to become more competitive (if the project succeeds). Kind of like Iron Man rebuilding the power supply for his heart and super-suit. It’s great, as long as it actually works. But it might kill you.

So who went down this path? The leaders tend to, because part of how they became the leaders in their markets is by looking for the next competitive edge, whether it is a technology, business process, or other. The interesting part is that in many ways it is more attractive for an *uncompetitive* company to attempt a radical technology and process overhaul, simply because what they’re doing is already *not* working. So it’s literally adapt or die. The implementation risks were substantial, sometimes companies suffered major setbacks through failed ERP adoption, Hershey’s being a the poster child for a disastrous SAP project, although it didn’t *quite* kill them.

Now let’s look at cloud computing. It is clearly a win for startups and insurgents in a given market. They gain IT capabilities and scale on par with all but the very largest organizations, and don’t have a sunk cost of equipment, staff, and existing business process. They can’t differentiate themselves on better IT per se, but they can develop their processes around the flexbility and scalability of the cloud, and design for competitive advantage within its constraints. They also have nothing to lose, so why not take the risk?

The more typical case is much more difficult. An existing enterprise already has substantial IT infrastracture assets, staff, and business processes. They will be severely criticized and probably sued if someone doesn’t like what they’re doing, which is problematic because they have an actual working business and assets. Nonetheless, in the current business environment, many existing organizations will be approaching that “adapt or die” point, in which the choices are to try something risky and maybe have it fail (in this case, moving IT services and processes to the cloud), or die (weighed down by higher costs and lower flexibility). One implementation risk is that the regulatory issues around privacy, security, accountability etc haven’t been worked out yet, and what major financial institution, bank, insurer, or health care provider would want to be the guinea pig in court? Not their first choice, but the prospect of lower incremental costs and the operating flexibility grow more and more appealing every day. Someone is going to be first, probably get sued, and then everyone will know what the rules are and jump in. Either that, or startups and insurgents in their markets are going to take over first.
