VirtualBox USB 2.0 errors

VBI was getting error messages regarding USB 2.0 when launching Windows virtual machines in VirtualBox 4.0+. The message mentioned loading the “Oracle VM VirtualBox Extension Pack”. Like Oracle’s VirtualBox, the extension pack is free.

The extension pack can be downloaded from the [VirtualBox download page]( It’s a one size fits all extension. The link is as follows.

Instructions for installing the extension pack are available [in the online manual]( I also found [abbreviated instructions]( in the VirtualBox forums.

Everything worked for me as advertised.

NASA-Funded Group Doctors Sea Level Data

James Taylor reports online at Forbes in the blog column Endpoint Analysis:


“Faced with the embarrassing fact that sea level is not rising nearly as much as has been predicted, the University of Colorado’s NASA-funded Sea Level Research Group has announced it will begin adding a nonexistent 0.3 millimeters per year to its Global Mean Sea Level Time Series. As a result, alarmists will be able to present sea level charts asserting an accelerating rise in sea level that is not occurring in the real world.”

The Rosetta Stone

Rosetta_Stone.JPGToday’s featured article on Wikipedia is The Rosetta Stone.

“The Rosetta Stone is a fragment of an Ancient Egyptian granodiorite stele whose engraved text provided the key to the modern understanding of Egyptian hieroglyphs. The inscription records a decree that was issued at Memphis in 196 BC on behalf of King Ptolemy V. The decree appears in three texts: the upper one is in ancient Egyptian hieroglyphs, the middle one in Egyptian demotic script, and the lower text in ancient Greek.”

This fascinated me when I was a child. What a remarkable find! Read the rest of the story at Wikipedia.


Project Management Software

I’m checking out project management software. Here are some interesting options.


  • OpenProj is a free and open source Microsoft Project clone, but it seems a little out of date. This appears to be a Java based application.

RationalPlan Multi Project


  • RationalPlan Multi Project offers some impressive multi-user options with a server component. This is a Java based application.



  • OmniPlan is a relatively new product from Omni and doesn’t have as many advanced features. This is a native Mac OS X application.

Today in 1947 — the ENIAC computer


1947 – ENIAC (pictured), the world’s first general-purpose electronic digital computer, was turned on in its new home at the Ballistic Research Laboratory at Aberdeen Proving Grounds, remaining in continuous operation until October 2, 1955.

The ENIAC’s design and construction were financed by the United States Army during World War II. The construction contract was signed on June 5, 1943, and work on the computer was begun in secret by the University of Pennsylvania’s Moore School of Electrical Engineering starting the following month under the code name “Project PX”.

Overtreated: More medical care isnt always better – Yahoo! News

> More medical care won’t necessarily make you healthier — it may make you sicker. It’s an idea that technology-loving Americans find hard to believe.

> Anywhere from one-fifth to nearly one-third of the tests and treatments we get are estimated to be unnecessary, and avoidable care is costly in more ways than the bill: It may lead to dangerous side effects.

> It can start during birth, as some of the nation’s increasing C-sections are triggered by controversial fetal monitors that signal a baby is in trouble when really everything’s fine.
It extends to often futile intensive care at the end of the life.

Terrifying Sinkhole Opens in Guatemala, Swallows Three-Story Building

Terrifying Sinkhole Opens in Guatemala, Swallows Three-Story Building: “Looks like you could travel to India — or another dimension — through this thing.”

The Guatemalan government posted this picture Monday of a massive 200-foot-deep sinkhole in the capital of Guatemala City, which opened after a weekend of heavy rain from tropical storm Agatha.

A three-story building and at least one man were swallowed by its gaping maw, which officials estimate to be 100 feet in diameter.

About 146 people have died across Central America since Agatha’s landfall, with Guatemala reporting most of the casualties, according to the Daily Mail.

Mudslides are mostly to blame, and to make matters worse, officials are saying ash from the Pacaya volcano has blocked drains. Ash is also keeping Guatemala City’s airport closed, which could hamper international aid efforts.

Sinkholes are pretty common in Guatemala, Florida and other spots; just last month, a farmhouse with four people inside collapsed into a sinkhole in St. Jude, Quebec.

Sinkholes form in places where the underlying ground layer consists of limestone, salt beds or other soluble rock, which dissolves in water. Groundwater coursing beneath the surface eats away at the rock, slowly eroding and destabilizing it. Often, new underground caves are created, which then collapse in catastrophic scenes like this one.

Unfortunately, not much can be done to prevent the phenomenon — other than hope you don’t get swallowed.”

GraphicConverter X for Mac

GraphicConverter XGraphicConverter X for Mac – Graphics editing program and much more. MacUpdate Mac Software Downloads.

This is a very powerful image editing and conversion utility. It’s not in the same class as Photoshop, but it doesn’t try to be. Things that are easy to do in Photoshop may not be so easy in GrachicConverter, and vice versa. As a shareware application, GraphicConverter doesn’t have quite the ‘polish’ of a commercial application, but at the correspondingly lower price, it really packs a lot of power and versatility.
