3D NAND - Die with M2 SSD

On 3/26/2015, Intel Corporation and Micron Technology, Inc. posted a press release touting their new 3D NAND Flash Memory.

In short, what this means is that they have created a new way to create higher density solid state memory… 3D Memory! They boast that this increases capacity by 3x and that boost of capacity comes along with a “significant cost savings, low power usage and high performance.”

Highlights

  • New technology that uses floating gate cells – 3x capacity than other production methods
  • Enambles the creation of smaller form factor devices with large storage – 2.5″ SSDs with greater than 10TB
  • New processes and techniques that will extend Moore’s Law for flash storage
  • Expected to increase both performance and endurance of the storage

Multiple Maps On a Single Page with jQuery

Computers, Programming, Web

I recently added a “locations” page to my website and was looking for a simple way to display multiple maps (Google Maps) on the page for the corresponding locations, without having to do a ton of coding or having to maintain a lot of JavaScript.

What I decided on was a simple jQuery implementation that uses data- elements to supply latitude (lat) and longitude (lng) vales for the map rendering.

Google Maps API Simple Async Loading

In doing some page testing on my site using the Google PageSpeed Insights tool I found that on a couple of my pages, one of the things slowing my page loads down was the loading of the Google Maps API.

There are a lot of articles out there talking about a ton of different ways to load the Google Maps API in an asynchronous (async) manner, this basically sums up what I found… Basically the simplest way, that actually works (and a way that didn’t work).

Ubiquiti UniFi Hotspot Customization

Computers

After getting a Ubiquity UniFi AP and controller setup, I decided to get the hotspot running, just for the fun of it.

The default UniFi hotspot is not bad, as far as a free setup goes, but it’s not very “clean” as far as a web system goes. I’m sure as the product develops along it will get cleaned up. But for a businesses use, out of the box, there is a lot to be desired.

So what I decided to do was to clean up the HTML, integrate a responsive UI template, and get things matched up to my website a little better with a logo and a similar color scheme.

downdimgd.com – Win32/DomaIQ Malware

Computers

I recently came across a website that would redirect users via an ad network to a site posing as a Java update page. The site as since been notified and fixed, but here are the details.
 
After sitting on a page for a little bit, the page would eventually redirect to a page that looked something like the page below (more details below). So you would be on a page you normally would visit, then in a few seconds, boom, you would be asked to install some malicious software!

RT 4 – Slow Page Loads And Apache CPU Spikes

Computers

I recently ran into a server running Best Practical Request Tracker (RT) version 4.0.8 that was having major performance issues displaying certain pages and causing the system to run out of resources.
 
What was happening was that when a user would click to view a ticket or navigate around a tickets information, it would take a few minutes for the page to load; on the server the Apache processes (httpd) would be spiked at 100% CPU usage.
 
Here is the output from top for the httpd process while this was occurring.

PID  USER      PR   NI  VIRT   RES   SHR   S  %CPU   %MEM   TIME+    COMMAND
