2015-02-15 Sunday - Sony VAIO VPCF23BFX/B SSD Upgrade

Last night I decided to bite the bullet and upgrade my Sony VAIO VPCF23BFX/B laptop with an SSD.  The Sony support site was less than useless...

As part of my research, I relied on the SSD section of Tom's Guide - and in particular, the recent article: Best SSDs for the Money, January 2015

My existing OEM HDD was a 640GB, 7200 RPM, Toshiba HDD2E81 MK6461GSY

I decided to go with a Patriot Ignite 480GB SATA 3 2.5 (7mm height) Solid State Drive-With Transfer Speeds of Up-To 560 MB/s read, 545 MB/s write. For simple convenience, I decided to get my unit at a local Fry's Electronics...although Amazon's price today would have been a bit better ($199.99).

The Patriot 960GB SSD was also a consideration ($547.99) - but as this laptop may become a secondary machine later this year - I'm looking at this as an interim experiment.

For cloning the original HDD, I decided to go with the Corsair SSD Hard Drive Cloning Kit (listed for $22.69 on Amazon today)

Removing the HDD was a simple process of removing the 8 screws:

  • [2] screws securing the HDD drive bay plate (on the bottom of the laptop)
  • [2] securing the HDD caddy
  • [4] securing the HDD to the caddy

For those unsure of just how to replace the HDD in their laptop, these two articles [link #1, link #2] may be of interest.

During the cloning process, I selected the advanced option to perform verification - which may have significantly increased the time it took to clone the HDD drive (~2.5 hours).

Overall, this was a painless exercise, and I am very pleased with the speed improvements. Booting Windows now seems to take about 25 seconds, and after login - my system is ready for work within 3-5 seconds (previously, with the HDD, this start-up phase... might take several minutes).

Another option I may consider in the future - a 2nd HDD SSD caddy using the laptop's optical drive bay

2015-02-01 Sunday - Microservices

The Seattle Java Users Group (Seajug) mailing list recently included a link that may be of interest to folks who wish to learn more about microservices...

And, you may be interested in reading the article by Martin Fowler and James Lewis (from March 25, 2014)

While attending QCon and Strange Loop conferences last year, I noted microservices were certainly garnering a large percentage of mind-share in the various scheduled sessions...

In my own consulting work, I have recently started working with a new client that uses RESTful services exclusively in their architecture (no classical Service Bus) - and most of which I would certainly consider classifying as microservices. This is quite a change from my last two client engagements (over the last 5 years) - who were strong adopters of the classical Enterprise Service Bus (ESB) - with heavyweight canonical message models.
