Last week the Australian Government passed the Telecommunications and Other Legislation Amendment (Assistance and Access) Bill 2018, which allows certain government agencies to issue secret notices compelling Australian IT workers and software developers to insert secret malicious code into any software or computer systems, for the purpose of gaining access to the content of encrypted messages […]

Raijintek Morpheus II

RX Vega 56 launched in August 2017 with a blower-style stock cooler that is incapable of adequately handling the excess heat from this GPU at its full performance level. The default settings deliberately limit the power consumption and fan speed to keep it running comfortably within its physical limitations. Can it be improved with a […]

Accelerated R with CUDA on Linux

The R programming language uses Basic Linear Algebra Subprograms (BLAS) for performing common linear algebra operations such as vector addition, scalar multiplication, dot products, linear combinations, and matrix multiplication. R includes Netlib BLAS by default. Significant performance gains can be achieved by replacing that with a different BLAS library such as OpenBLAS or ATLAS. Further […]

External GPU with Thunderbolt 3

The AKiTiO Node Thunderbolt 3 eGFX Box is a 7Kg black metal powered external enclosure for connecting a full-size graphical processing unit (GPU) to any computer with a Thunderbolt 3 port. The front 12cm fan can be removed to make room for a water cooling radiator. The carry handle helps it to be more portable […]

The Total Carbon Column Observing Network (TCCON) is a global network of instruments that measure the amount of carbon dioxide, methane, carbon monoxide, nitrous oxide and other trace gases in the Earth’s atmosphere. There are two TCCON instruments in Australia: Darwin and Wollongong (and one nearby in Lauder, New Zealand).

Visualising OCO-2 XCO2 in R with DeltaRho

NASA JPL’s Orbiting Carbon Observatory 2 (OCO-2) was launched into sun-synchronous orbit around the Earth on July 2, 2014. It carries 3 grated spectrometers for measuring the spectrum of sunlight reflected off the surface of the earth, which is used to calculate the average concentration of Carbon Dioxide in the column of atmosphere beneath the satellite […]
