Arduino Powered RFID Door Lock

regulate — Sat, 20 Mar 2010 01:31:56 +0000

I recently prototyped out a project that I thought was the coolest thing, a RFID Door Lock. I saw a cool instructable that shows you how to build a RFID powered door lock utilizing an Atmel AVR chip with the ever so popular Arduino firmware all for under $50!! Basically the microcontroller sends a signal to an electric door strike to open the door if the RFID card matches what is programmed into the memory. There is a master card that is used to program other RFID cards, you just swipe the master the led flashes to state it is in programming mode and then you swipe the new RFID tag and voila, it’s saved to the chips memory. A totally cool project, I invite you to check it out here.. Stay tuned for pics!

The High Cost of Losing a Developer

regulate — Wed, 18 Nov 2009 20:02:06 +0000

I recently stumbled upon an amazing accurate article about how it would cost double to replace a developer on a legacy / complex code base. Being a developer myself I find that as time goes on the more under appreciated talent becomes, maybe the adage of familiarity breeds contempt but retaining good developers is imperative to keeping costs down and projects on track. Getting a new developer up to speed at a small company could prove to be the company’s downfall. Check out the article here

Fixing a Broken MySQL Slave on Linux

admin — Wed, 04 Nov 2009 16:41:49 +0000

During a recent slave addition to our architechture I ran into a few problems getting the slave back up and running after it had stopped for a period of time. I ran into multiple errors which included Duplicate / Primary Keys, missing tables, corrupted binary log entries etc. The solution was to use a handy feature in a one liner that would loop through and restart the slave and increment the SQL_SLAVE_SKIP_COUNTER until there weren’t any errors being reported by MySQL. The handy one liner is as follows, hope this helps someone else out as much as it has helped me:

while [ 1 ]; do if [ `mysql -e "show slave status\G" | grep "Duplicate entry" | wc -l` -eq 1 ]; then mysqladmin stop-slave; mysql -e “set global sql_slave_skip_counter=1″; mysqladmin start-slave; fi; sleep 7; done

Your mileage may vary to get this to work with your system depending on the shell and the mysql settings you use.

Dumb .NET Choir Boys Bashing On Ruby

Here we go again, I work with some Microsoft choir boys who insist on bashing on something they don’t have any clue about.. Just because they can’t use a command line and need they’re precious GUI to do anything remotely useful they constantly bash Ruby and open source in general. It’s a sad day

The Search For a Good WYSIWYG

regulate — Sat, 27 Jun 2009 00:49:20 +0000

During our recent efforts at work to integrate a different WYSIWYG into our email marketing application we had decided to try out TinyMCE. Boy was that a bad idea, we ran into problem after problem with the open source WYSIWYG and the way it takes it upon itself to format the source and add all kinds of funky attributes to perfectly good tags. I was finding sizcache and sizset attributes in my table tags and it took it upon itself to wrap my source in it’s own container div, also using the fullpage plugin it could not even determine that they’re were html and head tags and kept duplicating those and sticking them in arbitrary locations. Basically it messed everyones code up and boy they were pissed!! This editor lacks clear and consise documentation and needs a lot of work. For an editor that is as mature as TinyMCE is, it’s sad that it is in the state it currently is in, I had to downgrade to get it semi working. Although I do sympithize with the developer as it is ever increasingly more difficult to write javascript to confirm to the ever changing DOM (or everyones different interpretation of it), especially with Microsoft’s one sided approach to making IE the worst browser in the world when it comes to following standards. Every browser has its own twerk and writing code for each one must be a nightmare, especially the complexity with writing a WYSIWYG as it seems no one can get it right. Hopefully someday this will change maybe when the browser makers can get on the same page but I don’t foresee that happening anytime soon, especially with Microsoft’s ability to throw a wrench in the works!

Happy Fathers Day!!

Ahh yes, another fathers day and a special one at that!! It’s is my first fathers day for me, a father to be!! I figured that would warrant a post to my blog which has been feeling neglected lately to say the least. In less than a month and two weeks I am going to be a proud father of a baby girl that we still have not been able to settle on a name for but we have some good candidates. Who knew coming up with a name would be so difficult, but i’m sure we’ll figure it out before she’s here. These past few months have been pretty nerve wracking from dealing with so called friends who really aren’t my friends, to trying to muster up motivation to tackle projects left on the back burner. Hopefully I can get everything sorted out before the baby comes. Either way I just wanted to wish everyone a happy fathers day and promise to start posting more technology related content ASAP… Thanks for visiting and I’ll be talking to u soon!

What happened to America’s healthcare?

admin — Wed, 31 Dec 2008 01:16:29 +0000

During a recent visit to my local hospital because my father was having severe abdominal pain, I was astonished by the amount of time they left him in the waiting room groaning and crying out because of his pain. They hospital staff could have cared less, even though there was hardly anyone in the emergency room.. Looking back on a recent article I had seen about a lady who had died waiting in the emergency room while the doctors, nurses and hospital staff were oblivious to the urgent attention needed for some patients just because they opt’ed not to take an ambulance to the hospital doesn’t mean they couldn’t have and are not sick enough to recieve immediate care. Sad to say she had passed away in the emergency room and was left there on the floor for hours on end. Who allows the hospital staff to behave in such a manner? I can understand being de-sensitized after seeing so much death and sick individuals, but aren’t they there to save lives and at least make people comfortable while they wait? I am disgusted with the way the health care system is in its current state and can only imagine how it will be when we have a public health care system.

New Hobby Time: Microcontrollers and Electronics

regulate — Tue, 30 Dec 2008 19:37:45 +0000

Well I’ve decided to pick up on a new hobby that relates the digital world that I live in other than more web development. I’ve recently been heading over to sparkfun.com and browsing their different products. To my delight they have all kinds of cool breakout and development boards that a hacker like me can fiddle around with. I picked up a new breadboard and an Arduino Duellimenov some LEDs and resistors and went to town. I got my blinky lights going at my desk and loving it like Mickey Ds.. I’ve been experimenting with the PWM (Pulse Width Modulation) which make the LEDs look more like candles flickering. I was lucky enough to grab a course book on Digital Fundimentals from a co-worker which will hopefully enlighten me with more knowledge about circuitry and microcontrollers. I’ve started learning on the Atmel AVR series and am working my way up to the bad boy ARM processor. I’ll keep everyone posted with my new stories and pictures of my new projects and creations. Well thats all until next time, keep in touch with yourselves.
