Socrative is a classroom app for fun, effective classroom engagement. No matter where or how you teach, Socrative allows you to instantly connect with the student receiving a instant feedback.
Using true or false or text questions is possible to generate reports to check the learning process
Text to speech is a important solution for several people, however, the application could be bigger. On linux the eSpeak is a solution. To install on debian: apt-get install espeak
espeak -v ‘en-us’ ‘Text test’
Git a simple system for version control system, with a basic steps is possible to install or compile git and start using.
cd gitrepo (with the code)
git init #init repository
git config –global user.name “user”
git config –global user.email “email@example.com”
git commit -m ‘initial commit’
git push master
git config core.bare true
git status #shows the changed files
git add -u #add changed files or git add -u
git commit #inform the changes
git push #send the files
ROOT from CERN is a very useful tool for data analysis for scientific data, with a C++ interface is possible to generate the plots and some data processing:
Generating plots like this one:
Molecular dynamics (MD) are based on a algorithm, the figure below shows the basic molecular dynamics steps:
For each MD step (lines 3, 4 and 5), is necessary to integrate the Newton’s motions equation, the Verlet algorithm is widely use for this task. However, there is a important issue to tackle, the Delta T has to be small (on 1 fs order) to minimize the error and result on a correct simulation. To solve this issue is possible to use accelerated molecular dynamics.
If you like to research, there is a lot of information on the web can be used. NASA, releases a lot of raw data to be processed. The Infrared Science Archive (IRSA) have a some TBs of image to with free images, the figure shows the data amount over the years.
Which is the minimum hardware for InfiniBand for HPC ?
– InfiniBand Adapter Card, Single-Port QSFP QDR IB (40Gb/s) ($495 ~ R$ 4000)
– Mellanox Passive Copper Cable, IB QDR/FDR10, 40Gb/s, QSFP, ($134 ~R$1200)
– Switch QDR 36-Port Managed InfiniBand ($10000 ~ R$50000)
For 10 computer nodes 10 x $495 (adpter card) + 10 x $134 Copper Cable + $10000 (switch) = $16290 ~ R$102000
For software, RocksCluster is very suitably solution.
Astronomy software was able to show the planets, today, we can process more imagens and events: http://www.upf.br/seer/index.php/rbca/article/view/4072
