An upcoming symposium on citizen science at Yale-NUS College, 3-4 March 2017 which will feature a mixture of talks and workshops, with the goal of increasing understanding of citizen science both locally and internationally. Anticipated topics are the role of technology in citizen science, and bridging citizen science with pedagogy.
All are invited to register to attend (free) at the registration page.
I have been having an interesting discussion with old friend Keith Phua about server migration to Github, Amazon S3 or Bluehost. This Thursday morning discussion was a long time coming, as first notice was served in April this year.
Keith has been providing me with tech support since 1999, when I first learnt a few HTML commands and how to FTP. I then was bale to become an early adopter of Science servers for webpages and blogs: these were wings to let me fly when it was most needed for mangroves, coastal cleanups, Chek Jawa, Habitatnews, Raffles Museum News, Otterman speaks… etc.
But now it is time to shift!
My many servers are mostly static and dynamic content can be pushed to blogs. Server access is low but the pages are evergreen and I am still referencing pages made over a decade ago. So where to migrate content to?
GitHub allows multiple repositories under a single account so I could push all files to a single site and map domains to relevant repositories. It is really meant for project management by geeks but there a desktop client which eases things for me. I’ll give it a spin and map the old domain to the github URL and decide about permanent residence later.
Nice to see my colleagues from Ridge View Residential College shopping for our herb garden. I’ve asked them to create a forest patch, vegetable garden and fruit orchard too!

In 2010, the late 2009 model quad-core 2.66GHz iMac with its large 27.1″ screen and 1TB 7200rpm hard drive was mind-blowing. And extremely helpful for tired eyes managing multiple windows. After half a decade, it seemed to slow to a crawl. In preparation for some intense use, it has been given a new lease of life with a long-awaited upgrade!
Shopping at OWC last week procured a 1TB SSD hardisk and 32GB of RAM. I paid close attention to the installation videos which had served me well when upgrading the Mac Book Air’s battery. And indeed, the process of replacing the hardisk and RAM ran smooth.
There were just two hiccups – the very strong magnets along the screen perimeter kept displacing the last eight screws. Eventually a tweezer was brandished and forced the screws to align, solving that problem. Then a missing Phillips #2 screwdriver threatened to upset the RAM installation but my handy bike tool came to the rescue!
It was nice to see some clean insides this time, because the cats can’t perch on top of this machine, and it was free of the heat-producing harassment of fur which peppered the Mac Book Air’s innards.
After six and a half years, it’s great to see the iMac experience a second wind. The old hardisk will continue its long life as an external drive once enclosed in a 3.5″ case, and the RAM will be recycled though OWC.
With each version of OS X, it is necessary to update NUS VPN to access certain university sites remotely. This prevented me from using the macOS Sierra beta version as the VPN software would not be updated until stable release.
The Pulse Secure version that works in macOS sierra is 5.2r5.0-b869, which is available from NUS Computer Centre at https://comcen.nus.edu.sg/eguides/
If you have updated your OS, you should go ahead and download this latest version.
About half of the new 22 km Murnane pipeline is being laid under the Rail Corridor, from Bukit Timah to Tanjong Pagar. This project lays a new set of water pipes to carry water from the Murnane Service Reservoir to Marina South & Fort Canning Service Reservoir in the city, to meet future demands and replace ageing pipes [link].
The work is being done in phases and the southern stretch of the Rail Corridor is being closed as follows:
PUB had discussions with the http://www.thegreencorridor.org/tag/murnane-service-reservoir/ before the announcement in June 2014.
Thanks to Jerome Lim for his many posts about this project since 2014 to keep us informed.
