- Do we need to add anyone else to the weekly meetings, e.g. Hossein Javedani of UTM. Saqib has tried to contact Hossein 3 times. He will try again.
- Johari proposes that UTM host a PingER workshop in 2014, maybe associated with another conference. Anjum will be in Malaysia then. Saqib will inform Hanan. Is there an update?

's thesis has around 130 pages. However, almost half of it is about generic stuff about Semantic Web. The other half is specific about PingER LOD project. The Semantic Web generic stuff part should be translated because I believe it is a good material for those who want to study and understand more about it. The PingER LOD part should be translated for further documentation about the project we developed at SLAC. Things Renan needs to do:
- Start translating his thesis, specifically the PingER LOD part (around 50 pages), which is more interesting to us.
- Test (free) alternatives for the RDF Repository, he has already started this. He just needs more time to test it more and have more solid results.
- Paper about Big Data and Social Computing for the conference that will be held at Stanford: He is pretty sure he can argue that we have made fair nice contributions for social computing using (big) data handling technologies. he will discuss with his professor at Rio so she can help him with advice. The deadline for the proposal (3 pages, easy) is Jan 15.
Renan is now working as a systems developer at his university at this moment so he is busy. He has plans to keep in touch with us and producing more work. JCurrently he is unsure he will have an outstanding productivity
He has also made some modifications on the ontology of the project (under supervision of his professor in Rio) hence he will have to modify the code to load the data accordingly.
He has presented his thesis paper. He will need to work on the presentation, including the website design and providing more info for the web page (pingerlod.slac.stanford.edu). He is producing good written material about PingER LOD, just wish it were in English already. He will have a hard time translating everything; but it is necessary since he did not provide good documentation about our project.
After the presentation he will be able work on the code (this has higher priority) and then on the RDF storage alternatives. He will perform more experiments with OWLIM Lite and Open Link Virtuoso, both free of charges. Need to verify if they are good enough for our 50M+ triples.

Ridzuan reports his current progress is that he has considered using Apache Mahout (open source machine learning for big data) for the clustering on the Pinger data. He is awaiting Renan decision on final implementation of RDF storage to be adopted. Then, he can start experiment with the new data structure. Renan should he wait or try with the old interfaces (pingtable.pl)? Renan recommends that Ridzuan wait for a week after his thesis defense on Dec 11, hopefully Renan will have something by then. Ridzuan, how did your tests with pingtable.pl go?

Raja has put together a paper on TULIP. Next step is to submit it.
As Raja's work on TULIP begins to go into testing he will be engaging more with Renan and Linked Open Data. Raja has sent email to Renan and has a list of things from Renan that Raja should look at. This is delyed by finishing off the TULIP paper and the end of year PingER annual report for ICFA.
PingER at SLAC
Les tried again with UFRJ (12/5/2013), making sure Renan is on the email so Renan can go beat on the door of the UFRJ contact. There was no response, Renan can you help?

- Click on Visualizations, there are two choices:
- Multiple Network Metrics: Click on the image: gives a form, choose from Node pinger.slac.stanford.edu pinging to www.ihep.ac.cn, time parameters yearly, 2006 2012, metrics throughput, Average RTT Packet loss and display format Plot graph, then click on submit. In a few seconds time series graph should come up. Mouse over to see details of values at each x value (year).
- A mashup of network metrics x university metrics Click on image: gives another form, pinging from pinger.slac.stanford.edu, School metric number of students, time metric years 2006 2012, display format plot graph, click on submit. Longer wait, after about 35 seconds a google map should show up. Click on "Click for help." Area of dots = number of students, darkness of dots = throughput (lighter is better), inscribing circle color gives university type (public, private etc.) Click on circle for information on university etc.
- etc.
- Renan will be working on providing documentation on the programs, in particular the install guide for the repository and web site etc. This will assist the person who takes this over.
Renan is using OWLIM as RDF Repository. He is using an evaluation version right now. Renan looked into the price for OWLIM (that excellent RDF Database Management System he told us about). It would cost 1200EUR minimum (~ 1620 USD, according to Google's rate for today) for a one time eternal license. It seems too expensive. No wonder it is so good. Anyhow, he heard about a different free alternative. Just not sure how good it would be for our PingER data. He will try it out and evaluate. He will also get a new evaluation of the free OWLIM lite.
He has also made some modifications on the ontology of the project (under supervision of his professor in Rio) hence he will have to modify the code to load the data accordingly.
Raspberry Pi
A quick comparison of the performance of the two hosts (raspberry pi and regular UNIMAS host) without statistical quantification is available at https://confluence.slac.stanford.edu/display/IEPM/Comparison+of+PinGER+RTTs+from+UNIMAS+monitors+N4+and+RASPBERRY. A page has been created to compare the hardware spec between the pinger.unimas.my node (Intel architecture) and the pinger2.unimas.my node (Raspberry Pi ARM architecture), available from the unimas pinger website at http://pinger.unimas.my/pinger/hardware.php. There is a link to hardware.php in the Comparison+of+PinGER+RTTs+from+UNIMAS+monitors+N4+and+RASPBERRY web page.
