Stinkhorn Mushrooms

The Phallaceae are a family of fungi, commonly known as stinkhorn mushrooms.
I have come across them in my backyard over many years. My daughters and I often wondered what the hell they are? They looked fearful and smelt rather offensive!

Ruthenium – a rare earth metal

Ruthenium has the symbol Ru and the atomic number 44.

Because of its ability to harden platinum and palladium, ruthenium is used in platinum and palladium alloys to make wear-resistant electrical contacts.

Currently, 50 percent of the ruthenium is used by the electronics industry and 40 percent is used by the chemical industry, whilst the remainder is primarily used to create alloys of platinum (for jewelry) and titanium (for corrosion-resistant underwater pipes).

Parker pens uses ruthenium to make the nib of its “RU” fountain pen: the nib is 14-carat gold with a ruthenium tip!

eScience – Data Intensive Science

Data-intensive science – a new research paradigm
Data-intensive science is now taking a place alongside theoretical science, experimental science, and computational science as a fundamental research paradigm.

What is data-intensive science?
Data intensive science is now taking a place as a new fourth fundamental research paradigm. Why is that so?

Currently, the enormous volume of scientific, financial and business data from data sensors, automated machines and computers. The data deluge from social media. That is why! The data will need to be stored, curated, annotated, archived and shared by researchers effectively and efficiently. This generates a new set of demands.

Cloud computing infrastructure was created to deal with the Internet’s sheer data challenges.

The new demands will mean new data services for storage, sharing, curation and access. The quantity and availability of data also mean the new demand for new analytics. Powerful data visualization engines, complex system modelling tools and machine learning algorithms are needed to cope with the ever huge data sets.

“The impact of Jim Gray’s thinking is continuing to get people to think in a new way about how data and software are redefining what it means to do science.”
— Bill Gates, Chairman, Microsoft Corporation

Till next time

Interactive Digital Signage

Hello earthlings,

This is my second post on all things related to science and technology. I will keep my posts brief so I can keep up and write posts regularly. This time I will look at interactive digital signage. This is the next big thing after smart phones and tablets.

What is digital signage?

Digital signage involves the electronic display which shows television programming, interactive menus, advertising and other electronic messages for the public.

Digital signs (uses LCD, LED, plasma displays, or projected images to display content) can be installed in different environments such as retail stores, hotels, restaurants, and corporate buildings for example.

The “Content” is the name used to describe anything designed and displayed on digital signage or large digital screens for public consumption. Content Producers are the people who prepare and publish digital information.

Consumers are the people who participate or consume information from the digital signage.

Interactive signage solutions such as touch-screen kiosks will pop all over the place very soon. Stay tuned for the proliferation of digital signage!

Transit of Venus capture

I used my Meade Spotting Telescope and my iPhone to take photos of the projection of the transit of Venus on my clipboard on 6th June. The author, Deaf Dave has a goatee at the moment. Normally he is a squeaky clean guy…
