Understanding HotSpot in Plain English

Not having a degree in Computer Science means that my view of web technology begins at a granular level and necessarily seeps from the top down into the foundations of how software works. For ColdFusion this course traverses the basics of HTTP and CSS, expands into the full range of CFML tags, functions, and architecture, then arcs into databases and SQL, and continues well into the depths of Java and J2EE technology and all that's contained therein. One low level topic that has often piqued my interest has been the question of what exactly is the Sun HotSpot technology for Java Virtual Machines? Sure many ColdFusion pundits share recommendations for JVM tuning parameters, but if you're like me you find it rather superficial and want to know more about this HotSpot black box.

The Real Patriot's Day: Dawn Salute at Buttrick Hill in Concord

This morning I had the opportunity to attend the annual Remembrance Ceremony held on April 19th at Buttrick Hill in Concord, MA, adjacent to the North Bridge. The event heralds the arrival of Samual Prescott on horseback at the North Bridge to warn the hundreds of militia of the pending arrival of British troops from Boston on the morning of April 19, 1775, and the ensuing start of the Revolutionary War.

Its not often that I'm awake at 5am, but I was pleased to find the event well worth my effort. The ceremony lasted about 30 minutes from the cries of "Samuel Prescott" galloping across the bridge until then the end of the dawn salute with blazing muskets by the resident militia.

For some additional photos from another spectator, including some very nice photos of Dr. Prescott on horseback, see these.

Teye and Belen, Flamenco at Club Passim

Last weekend my wife and I spent a fantastic evening watching and listening to Teye, a dutch flamenco guitarist, and his Spanish wife Belen, a dancer from Sevilla. Club Passim sits unnoticed in a Harvard Square alley, half sunken but with many windows to let in the light on the lower level. The atmosphere was small and friendly as though one were in a living room, and Teye was eager to chat. Belen began by accompanying the guitar while seated on a percussion box - a cajon - where she slapped out the staccato rhythms of Flamenco. From there she leaped into brilliant dance, strutting, twirling, and tapping her way into what seemed like a frenzy. Teye's guitar playing was equally hypnotic while his hands were all a blur as he thrashed the strings. If you have an opportunity to see them perform, you must.

Annotations for ColdFusion Podcast Episode 21: Performance Tuning

I enjoy keeping up with the ColdFusion Podcast whenever I can, but I usually lag behind by a couple weeks until I find the time to listen to a few of them during some downtime. This morning I began listening to the most recent podcast at home, and then continued during my drive to work. The podcast was so interesting that I found that I had to share my right hand between the manual shifter and a notepad where I was jotting down some thoughts regarding Episode 21, Performance Tuning ColdFusion MX Applications.

Here I'd just like to take a moment to annotate some of the bullet points from the discussion while also extending with additional information.

Better to edit jvm.config manually than thru Java/JVM page of CFAdmin

There have been at least two bugs in the ColdFusion MX Administrator's ability to properly update the JVM settings in cf_root/runtime/bin/jvm.config when using the Java/JVM page to enact the change. A technote was just released for How to upgrade the JVM shipped with ColdFusion, which demonstrates how to change JVM settings from the Administrator. I recommend that you familiarize yourself with the contents of the jvm.config file and carefully edit the file by hand instead, after making an original back up copy.

My First Photo Contest, A Main Street Point of View

The Concord Museum called me this week to let me know that I won the photo contest for A Main Street Point of View. This weekend I visited the museum's Brooke Hall to see my photos on display, where they will remain for the duration of the museum's exhibit of the same name as the contest. My prize was a gift certificate to Anderson Photo, the cosponsor of the contest, along with a few museum passes to give out. Here's a litte more background about the contest.

There were only nine photographers contributing to the show, but it was my first photo contest so I'm very proud anyway.

Stacking up the IT Certificates

If you're in Massachusetts, you might want to know that the Boston chapter of the IEEE is holding a 21 hour course on an Introduction to Java Servlets and JSPs, using Head First Servlets & JSP as a guide. This local chapter of the IEEE has a fantastic continuing education program. This Servlet and JSP class will run on Monday nights from late April to May at the Sheraton in Lexington, right off Rt 128. The price is very reasonable at around $550, a bargain at less than $22/hour.

The course perfectly complements the Java and J2EE certificate program that I'm taking at Boston University on other nights. In fact, the IEEE course on Servlets and JSP overlaps with the BU classes on JSP and Servlets.

Using these complementary courses to propel me, I expect to take the Sun Certified Developer and Sun Certified Web Component Developer exams at the end of June.

In mid-April I'll retake the hottest certificate exam, the RHCE. (Update: Mission Accomplished!)

In May I'm scheduled to finally attend the Moving Up to ColdFusion MX 7 and Advanced ColdFusion MX 7 at RemoteSite Training, and I'll follow that up with the ColdFusion MX 7 certificate exam, too. This will be the first time I've had ColdFusion development classes since 2000 with Fast Track and Advanced CF4.5.

On a couple upcoming weekends I'll be taking the Stanford Computer Security Certificate Program, an 8 hour online course in Computer Security Principles, Introduction to Cryptography, and Secure Programming Techniques. The course is concluded with an online exam.

Once these Server and Programming courses are over, I'll add to my 40 hours of Photoshop CS2 training from TotalTraining and try to knock out an Adobe Photoshop ACE certificate this summer or fall.

I feel like I've been progressing well on many related technologies, ... getting my ducks lined up, so to speak. This will be the year to knock them all in.

Recommendation for BodasDVD Wedding Photographer of Barcelona

I highly recommend Bodas DVD wedding photographers in Barcelona, Spain. They met with us on several occassions the year of the wedding to coordinate the plan and requirements, and they were very accomodating to our wishes. They even traveled 4 hours to the wedding without charging us, although we did provide a hotel room for them. Carlos and his collegues were very helpful and patient throughout our wedding day. The result was a one hour interactive DVD movie of our wedding and a beautiful, leather bound wedding album of 20"x30". Everyone to whom we showed the album commented that they've never seen such a beautiful and unique album, and they all complemented the photographer's skill and style. Carles de Gispert also runs the multimedia business of Inedita and IneditAleph, and regularly uses Adobe image and video design products.

A Main Street Point of View - Concord Museum holds photo contest

More information here, but Anderson Photo is hosting a photo contest of Concord's main streets while collaborating with the Concord Museum. The museum is hosting a show of the same name, and I gather that the contest is a way to draw attention to and benefit both parties.

I stopped by Anderson Photo just this morning to provide my 3 entries printed in their original aspect ratio on heavy weight archival matte paper. The rules do not state that the photos must be 8x10", nor do they say that they must perform the printing and matting. Rather, the rules suggest that they will do the matting for you if you provide an 8x10, and they specifically say it is permitted to submit photos in print form. They firmly let me know that the prints are required to be 8x10 and that they must do the printing in glossy or satin, but not matte. Rats!

You can imagine that I was rather unhappy when I was abruptly told that my 7x10" photos were not acceptable and that Anderson Photo must do the printing. I tried 3 times to contact the owner Lynda Anderson but she was not available since she arrives late in the day, but then was out walking her dog when I called at the time I was told she'd be in, and she has not returned my email inquiry on the matter.

Update: Can you imagine how ticked off I was after all this hassle from Andersen Photo that when I arrived to see all the contest photos on display about half of them were NOT in 8x10 format. Why did they give me such a run around for then? /END RANT
