There comes a time in pretty much every programming project when you need to communicate with a database of some sort.  When doing this in Java, one choice is to manipulate DriverManagers or DataSources directly.  However, if you want to take advantage of POJOs to represent your data from the database, manipulating data as objects, you might be staring down the task of writing all sorts of ugly reflection code or a really long constructor to make this happen.  There is an alternative: the Java Persistence API. Old news, buddy! JPA is old-school, clocking in at over 10 years old!  (Jeez, I might as well bust out my IBM 5150 .)  However, I did not feel like writing reflection like what was done on the last project, so I searched for an alternative.  JPA provides you a mechanism to add in details pertaining to object/relational metadata (ORM), and thus run all sorts of CRUD operations with minimal code, by offering convenience functions for these oper...

Recently, I dug up an old email where I was musing on the big marquee on an old television game show called The Magnificent Marble Machine .  It was a very fancy prop at the time, as most television shows of the era relied on art cards with big, bold letters that would be flipped, slid, or otherwise revealed by stagehands upon the emcee's verbal cue.    k Slide it, Earl!

( Family Feud ) - Sources: YouTube, Game Show Utopia This is about as fancy as it got for electronic graphics on game show props in the 1970s ( Tic Tac Dough ).  However, they never upgraded this board during the 1980s...

Lately, I have been working with the LTC4151-1 chip by Linear Technology.  It is used to measure voltage and current with high resolution typically in telecommunications equipment.  In the process of validating my design, I need to test it with the simplest circuit possible in order to simplify fabrication and eliminate variables introduced by other intermediate devices (namely, the required optoisolators). The LTC4151-1 chip communicates over the I2C bus.  Only problem: its setup breaks out the SDA (serial data) signal into SDAI (data in from the microcontroller) and /SDAO (data out to the microcontroller, inverted).  It is broken out like this (with SDAO inverted) so that people can conveniently wire up optoisolators to reconcile different ground potentials that exist between the MCU and the unit whose voltage is being measured.  (Many times, the V- out of the battery will not be the same as the GND used by your microcontroller logic, computer, or etc., espe...

Lately, I have decided to write the front ends for my personal Web projects in Polymer .  It gives me the ability to construct the UI, and even tie in AJAX actions and database calls , by simply including Web Components as elements in the DOM, just like plain HTML.  To me, it seems less bloated and denser than even Angular 1 (sorry, haven't played with Angular 2 yet), not to mention plain JavaScript or JQuery where you still need to write out most of the interactions between the model, view, controller, and external APIs yourself.  The Web Components aspect was most appealing to me because now I could leverage previous work, standing on the shoulders of giants, rather than reinventing the wheel for the needed interactions.  Better yet, if I use Google's implementations of Web components, I can even get Material styling on my DOM elements with no extra work. However, Polymer suffers from some of the problems I've had with Perl too.  You really need to be in t...

The place I work at during the day tries to foster a whole lot of creativity as we tackle tough problems from many different angles, starting with carefully designed user experiences and including the best performance and functionality in order to delight our customers.  We have incredibly talented people working as leaders and contributors on our tech and design teams, and it takes lots of incentives in order to keep a team such as this together without suffering from attrition.  Many of my coworkers came from the startup world and, for all we know, are only trying to pay off some bills while chasing their great big hit on the side. One particular perk I've had a big hand in lately hasn't quite been mentioned on the Internet yet that I could tell, other than hinted at within various event invitations that you could probably dig up if you tried hard or maybe within social media interactions originating from the attendees, thus I'll refrain from talking about that particul...
