FTP problems with Linksys e4200 router

FTP problems with Linksys e4200 router

Mar 20, 2015 by Paul White

Updates on your hardware with new software is usually a good thing,  Except when those updates break things.  This turned out to be the case for people with the Linksys e4200 router who were updating to the latest 1.0.06 Firmware.  It was impossible setup USB devices as FTP or Media storage due to a new (Feature) where sessions would be passed in the Querystring as part of a security update that Linksys added.

Ebaying Hard Drives, Server, RAID Controller, Computer Parts

Ebaying Hard Drives, Server, RAID Controller, Computer Parts

Nov 19, 2014 by Paul White

Anyone who works in technology is usually surrounded by the clutter of old hardware.  Over the years I have upgraded systems where the old components were no longer needed, be it memory, or Hard Drives.  So my office had slowly become a graveyard for perfectly good but older hardware.  Finally after getting ahead of my inbox, I decided to conquer my office clutter and do an Ebay blitz to sell off this stuff.  After all Technology doubles in power every 18 months ( Moore's Law ), but this also means it depreciates by 50% every 18 months ( My Law ).  Holding onto old hardware thinking that someday you might need it again is a bad habbit for most of us.  It's time to sell it.

RocketRaid 4520 and WD 2TB Green Drives a recipe for failure

RocketRaid 4520 and WD 2TB Green Drives a recipe for failure

Aug 5, 2014 by Paul White

A couple months ago I colocated my new server, and have been slowly migrating all the data from my old server to the new one.  All this time, the new sever has been solid.   That was until last night.  When my raid card decided to drop a couple drives.  Making the system unresponsive, resulting in about 6 hours of downtime while My datacenter guy and me tried to diagnose the problem and get it back online.  For anyone thinking about putting WD green drives in a server, you might want to rethink that.

HighPoint RocketRaid 4520 Raid Card SSD Benchmarks and Review

HighPoint RocketRaid 4520 Raid Card SSD Benchmarks and Review

Feb 21, 2013 by Paul White

I took a gamble and decided to try Highpoint's latest flagship Raid Card ( RocketRaid 4520 ) for my new web server.  Naturally when I get a new piece of hardware I like to put it through some benchmarks to see if it really performs the way it should.  When this combined with your Operating System's Buffering and Caching this card is Excellent, but when Direct I/O is tested is falls short.  To make a long story short, the Rocketraid 4520 does not perform well for IOPS at 4K.  I have already contacted HighPoint and they inferred that their engineering team is aware of this, and are working on a new firmware that should fix the issues.

How to Measure your Server's Disk Writes for SSD consideration

How to Measure your Server's Disk Writes for SSD consideration

Jan 18, 2013 by Paul White

Before anyone considers throwing an SSD into your server, its important to be sure your server is not going to destroy that SSD with writes after a few months. In this guide I will show you how to use Performance monitoring in Windows Server 2008 R2 to determine what kind of write activity your server is currently doing. Then after that we can calculate our daily and annual writes, allowing us to determine how long that shiny new SSD will last in our server.

Which SSD should I use in my Web Server

Which SSD should I use in my Web Server

Dec 30, 2012 by Paul White

I am currently building a new Server for Colocation. This time around I am going to use SSD drives instead of the 15K SAS drives. Even though the 15K SAS drives have been reliable performers, the newest SSD drives simply blow them away in terms of IO. However SSD drives have a few issues you should be aware of. Wear Leveling! But before you decided that SSD drives are too much risk for your server, do the math, and ask yourself, how much writing does your server really do.

Save Money by upgrading from LCD to LED Monitors

Save Money by upgrading from LCD to LED Monitors

Mar 30, 2012 by Paul White

If you read my previous blog post, you know that I was having a little trouble with my Samsung 2493HM Syncmaster LCD monitor. I actually have 2 of them on my work station. I finally gave up on trying to repair it after the repair failed twice. I have upgraded to Dell 24" LED monitors. LED monitors cost a bit more than their LCD counterparts, but the cost savings in energy are worth it. I break out the kill-a-watt meter and put my old monitors against my new ones.

How to Fix a Samsung SyncMaster 2493HM LCD Monitor

How to Fix a Samsung SyncMaster 2493HM LCD Monitor

Mar 9, 2012 by Paul White

As some of you know I have invested into some serious desktop real estate. I have 3 Samsung Syncmaster LCD Displays. One is a 30" and the other 2 are 24". Everything has been working great for years. Then one of my displays ( Samsung Syncmaster 2493HM ), starting to randomly go out. Then it would make some weird clicking sounds. After a while it would make a loud pop and come back on. Occasionally it would also flicker before going out. Over time it got worse. After some researching, I figured out the problem, and was able to repair it myself for about $20 in Parts.

Super Talent Pico C USB Flash Drive Review and Benchmarks

Super Talent Pico C USB Flash Drive Review and Benchmarks

Nov 18, 2011 by Paul White

I finally decided that my old USB flash drive was taking up a little too much bulk in my pocket.  That and I was close to maxing out its 8GB capacity.  So I upgraded to a Super Talent Pico C USB Flash Drive.  This is by far the smallest USB drive available ( That I know of ).  It also comes in Chrome, Silver, and 24K gold plated finishes.  Bling and Nerd Credit come together.  I know the question many are asking.  Is it all show and no go?  I put both my old drive and my new drive through some benchmarks for comparison.

Unplugging from Cable and Phone but keeping internet

Unplugging from Cable and Phone but keeping internet

Sep 20, 2011 by Paul White

After getting our last bill from Comcast, I decided that I really don't need Cable or Phone.  After all both my wife and I have cell phones with unlimited talk, and even though we do occasionally watch TV, the quality of entertainment in my opinion has gone to crap.  I was able to shave $80 off my Comcast Bill, by keeping the internet only and buying my own DOCSIS 3.0 modem to avoid their $7 / month rental fee.
