My, what a tangled web we weave! This morning the Northstar Nerd may be found among the corn fields of rural Illinois, a few weeks ago I posted about Silicon Valley vs. Lake Superior Hot Spots. However, most of my visitors today come from the New York Times' article on data visualization. Yes. as I get ready to head back to Minnesota, the NY Times featured my tutorial on Data Visualization.

Exploit the virtues of immutability. Design your application around stateless abstractions interacting with each other through asynchronous message passing. These are some of the mantras that I have been trying to grok recently. In a typical Java EE application, we design the service layer to be maximally stateless. What this means is that each individual service has localized mutability interacting with other services on a shared-nothing basis.

The Web has an interesting property that those building Web applications and online businesses usually encounter soon after they first launch: It has its own unique and unforgiving rules for success and failure. Appreciating them requires a certain level of understanding of the intrinsic nature of the Web and how it works. Actually leveraging those rules requires an even deeper and more profound understanding of the Web.

IT lacks a consistent definition of exactly what it does vis-à -vis its organisational peers. Accounting is the language of business. Finance is how business gets capital. Marketing creates customers. Sales brings them in. Operations are how a business creates value. IT does … what, exactly? Creates new business offerings? Retains customers? Is how business gets done?

Software leaders who are building applications based on Large Language Models (LLMs) often find it a challenge to achieve reliability. It’s no surprise given the non-deterministic nature of LLMs. To effectively create reliable LLM-based (often with RAG) applications, extensive testing and evaluation processes are crucial. This often ends up involving meticulous adjustments to prompts.

Going back to my high school days in the early 70's I've always needed to know how to use statistics for solving technical problems. Back then I used a slide rule; now I use a high power PC. Hopefully my answers are still correct! One software package that I have used in recent years is Minitab. Recently I found an excellent online text book which covers Minitab 15. from "frequency distribution" to "confidence intervals" and "hypothesis testing" I will add this te

Jason Sobel has an interesting post on scaling out of Facebook on to a new data center in the East Coast at Virginia. A really interesting insight into some of the design decisions that have given us one of the most trafficked sites on the face of the planet today. Here are two points that struck me on reading the post. Changing the sql grammar in the replication stream to incorporate eviction of expired items from memcached looks like a hack.

At times all the heavy technical training can become a drag, and one needs a lift. One of my favorite engineering blogs, The Curious Cat Science and Engineering Blog, helped me with a fix of engineering humor: An Engineer's Guide to Cats. I discovered the technical aspects of cat yodeling and aspect ratios. Have some fun!

One challenge for many large companies is. how does one encourage innovation and creativity in corporate environments which often push employees to make "safe" decisions? After all, isn't product feature creep the easiest way to enhance what one already knows? Our customers always want more enhancements to existing products, or so we think!

In my last post on Scala actors, I had mentioned about the actor code being side-effect-free and referentially transparent. James Iry correctly pointed out that Scala react is side-effected, since the partial function that it takes processes a message which is neither a parameter to react nor a value in the lexical scope. Sure! I should have been more careful to articulate my thoughts.

Multi-tenant architecture allows software vendors to realize tremendous efficiencies by maintaining a single application stack instead of separate database instances while meeting data privacy needs. When you use a data warehouse to power your multi-tenant analytics, the proper approach is vital. Multi-tenant analytics is NOT the primary use case with traditional data warehouses, causing data security challenges.

Recently I had the opportunity to visit friends in Silicon Valley. While riding the light rail in Mountain View, I experienced a moment of revelation of how life differs between the shores of Lake Superior and Silicon Valley. Six young men boarded the train. all obviously geeks in their young 30's. their laptops (all Apples) were already fired up and ready.

Do you Google? Would you like to be automatically informed of relevant Google results that match a query you pre-define? Does tracking those Google results via RSS appeal to you? Assuming the answers to these questions are "yes", then you need to use Google Alert. This service allows you to create RSS feeds and/or email notifications against your Google query results.

How many of you really pay attention to what you hear when you take a walk. Those of you who wear iPods may miss out on much of life which is happening around you.

We adjusted our walk and arrived in time to find the two youngster's having a food fight over a fresh kill.

It's 90 degrees outside today. and humid. While it may seem hard to think about Winter during this kind of weather, earlier this week I signed up for three long distance cross-country races. The longest is the American Birkebeiner at 52 kilometers or 32 miles. Although I was not planning upon doing another round of ski races this Winter, the devastation wrought by the Sichuan Earthquake in China has changed everything.

The buzz around generative AI shows no sign of abating in the foreseeable future. Enterprise interest in the technology is high, and the market is expected to gain momentum as organizations move from prototypes to actual project deployments. Ultimately, the market will demand an extensive ecosystem, and tools will need to streamline data and model utilization and management across multiple environments.
