My first post in 5 years. I’m alive and well

A lot changes in 5 years, where it be in your personal life, social circle or career. It’s been a pretty busy five years since my last post on my website (just checked and it was on 2011/10/20)… so wow 5 years is a long time and a lot has changed since then.

You may be wondering why I stopped posting System Administration tips/code snippets and solutions to problems I have had for the past five years, mainly I have nobody but myself to blame for not dedicating time to writing up more articles but the trigger that caused me to go offline for so long had to do with a security vulnerability that my blog software (wordpress) suffered; back then in 2011 someone had decided to exploit my blog and redirect all my web traffic elsewhere.

As a “nuke it all” overkill solution I decided to take down the website, place a simple index.html site and thought to myself “I will fix my website when I get some free time and wordpress fixes their security” – this also happened during my senior year in college so my time was limited. I was running around trying to finish my last couple of high level courses and my final project to graduate while at the same time working part-time to pay for school.

The good news? In mid 2012 after 5 years at California State University Fullerton (CSUF) I had finally completed all my courses and obtained my Business Management Computer Information Systems degree. Shortly after that I started concentrating on my career. My internship at a major bank in southern California had yielded me a nice full-time job offer right out of college and so I went from being a full-time student into becoming a full-time Network Operations Center Technician.

During my time working in a Network Operations Center (NOC) I learned a lot about being a part of corporate america, but I learned way more about networking. This incentivized me to pursue and become better in networking by studying and successfully obtaining the Cisco Certified Entry Networking Technician (CCENT).

The thirst for more career growth

Work at the bank was good, but my learning had plateau for a good 12 months and opportunities to transfer into a Network Engineer role was non-existent, so I started looking elsewhere for opportunities while still working full-time at the NOC.

A few weeks into my job search I came across an opportunity on LinkedIn for a very small company I had never heard from before, they claimed on their website that their business was digital media and asset delivery. At the time I did not understand much other than some sort of transcoding in the cloud was what they did.

Sure enough, submitted my resume and the next day received a phone screen and an invite to come for an onsite interview in their office in Los Angeles. The job opportunity was for a linux system administrator role with networking duties in a datacenter environment.

Although in my professional career I had never used Linux, I did have some personal experience with Linux as I had been experimenting and using Redhat Linxu 7.2 since the early 2000s (back when Redhat was free! and wayy before Fedora even existed). After a written technical test on linux, of 25 questions or so I did get about 17 of my answers right and so I ended up with a job offer as a System & Network Engineer.

I was excited, I decided to take the plunge and leave a relatively safe position at a bank with no growth into the unknown of a job that depended on my linux skills. It was a perfect mix as I would still be able to use my networking skills by being responsible of the datacenter deployments in Los Angeles for this little company that had just hired me.

The green card crusade is finally over… and the job at Google

Fast forwarding a couple of years, I was able to finally get my green card after waiting in line and dealing with all the red tape that is involved with trying to become a permanent resident the right way.

Around the same time, I had accepted a job offer with Google in their Los Angeles office and that is where I have been for almost two years. During my time at Google I still try to learn new skills on my own and play around with new technologies, just a few months ago in October 2016 I attended PuppetConf 2016, studied and passed their Puppet Certified Professional 2016 exam.

As you can see, it has been a pretty busy five years for me. A lot of learning, growth, career moves and finally achieving one of my most ambitious goal, becoming a U.S. permanent resident.

What’s next for 2017?…

Learning never stops and if there is something I regret is not bringing back my website back online sooner. I have worked on some cool things and have found a couple tips and solutions that originally took me several days or even weeks to learn. As a first step for the next year I am hoping to be able to use my blog again to help people find all this information and help others grow.

The technology landscape also keeps continually changing, recall my post discussing building a vmware ESXi (all-in-one) server. Nowadays there are exciting new technologies like Docker that I am hoping to dig into it myself sometime soon.

Apple iPhone 4S Cellular Network comparison AT&T 3G vs Sprint 3G (video)

Last week Apple released the newest iPhone 4S in the United States for all three major wireless carriers: AT&T, Sprint and Verizon.

As an iPhone user I wanted to compare the wireless networks of AT&T, my current carrier since the release of the iPhone 3GS in 2009, and Sprint the defacto Unlimited data wireless carrier since all data plans from the other major carriers carry a data-cap.

This is the first time that Sprint carries Apple’s flagship phone and despite the amaizing features of the phone, as you can see in the video, the wireless network of Sprint falls short of expectations for a proper iPhone experience to support YouTube streaming, data downloading, etc.

Further the video shows AT&T constantly offering amazing speeds (probably thanks to HDSPA+ wireless data technology only available for AT&T iPhones) in comparison to Sprint’s poor network performance during ping, download and web browsing tests.

For the time being AT&T will keep me as a customer, thanks to their superior data speeds and thanks to fact that AT&T is the only carrier to support web-browsing while on a call. If Sprint enhances their network to offer at least 100 KB/s (1MB steady downstream) they may become the defacto winner for new and current iPhone users looking to save some money (I could save $15+ a month by switching to Sprint). However due to their poor network performance I decided to stick with AT&T. I would love to hear about your experiences with the Sprint iPhone 4S on their network.

Building a low power Sandy Bridge ESXi + ZFS Storage Array

I have finals this week, so I will update this post as I have more time. In the meantime, I am working to get vmware ESXi (free version of vmware Virtualization server hypervisor) onto a custom whitebox build to replace my aging Intel Core 2 Quad Q9450 server that uses around 125 Watts while idle.

Find disk by id in Linux

You may be wondering why linux is not pointing to a standard /dev/sdX for your SATA hard drives. When you come across a reference to a hard-drive in the ID form like this:

Spring Break is here… Acronis True Image and Gigabyte Motherboard don’t play nice

Finally got a break for school, which means that after work I can get home and play with my toys instead of doing homework. This weekend I set myself to fix my video card so that I can once again use my three monitor screens on computer (it stopped working awhile ago).

So I went out to Frys Electronics and got myself another video card that I could match up with my old ATI RADEON 4870 512MB DDR5 via Crossfire. Crossfire is a protocol from ATI/AMD that allows you to use two video cards as one for better performance.

Quick C# Programming Notes on String Formatting

Here is a few examples on the different ways to format strings when outputting data to the user. Computers usually store numbers without formatting.

Some of these notes will tell you the exact code you would need to make a computer’s “224” to be outputted as “$224” or “224 %”.
