Its my first time working with cygwin so bear with me please.
I need to install a processing library via cygwin in order for it to work.
I followed all the steps in this tutorial and in the last step (00:22 seconds mark) I need to "cp" LeapMotion to the directory where Processing stores it's librarys.
I store mine in "D:\Processing Sketches\libraries" and i don't know how to copy it there. I'm confused with the ~/home/ part.
I tried "$ cp -R LeapMotion /D:/Processing\ Sketches/libraries/" but that doesnt work :/
Under cygwin DOS drive letters are mapped to /cygdrive/<drive>, so you would do it like this:
$ cp -R LeapMotion /cygdrive/d/Processing\ Sketches/libraries/

On Ubuntu, I installed Atom from the .deb package. But I mistakenly run it as root on the first time.
Then I get this error:
$ atom
$ /usr/bin/atom: line 185: /home/fabien/.atom/nohup.out: Permission denied
A ~/.atom directory has been created with the root privileges.
It can be solved:
by changing the ~/.atom owner:
sudo chown -R -v <username> ~/.atom
by simply removing this directory:
sudo rm -fr ~/.atom

I need to query this curl code in R:
curl -u user:pwd \
-k https://localhost/adapars/apply/Iris_NN?maxThreads=8 \
-X POST -F \
file=#Iris_NN.csv
I am using RCurl but I don't really see how to do it.
in httr
not tested, but:
library("httr")
url = "https://localhost/adapars/apply/Iris_NN?maxThreads=8"
POST(url, authenticate("user", "pwd"), body=list(file = upload_file("Iris_NN.csv")))

I need to use sbt for run spark in my fedora box, but what surprised me most is
sbt cannot use in my Fedora, I've tried two fedora machines, both failed.
I guess a lot of people meet this problem before, any ideas?
Thanks.
Jovi
UPDATE
For RPM based distributions ( http://www.scala-sbt.org/0.13/tutorial/Installing-sbt-on-Linux.html ) following instructions work:
curl https://bintray.com/sbt/rpm/rpm | sudo tee /etc/yum.repos.d/bintray-sbt-rpm.repo
sudo yum install sbt
OLD INSTRUCTIONS
Setting up SBT on fedora is pretty straightforward.
Older version sbt-0.12.2:
$ sudo yum localinstall http://scalasbt.artifactoryonline.com/scalasbt/sbt-native-packages/org/scala-sbt/sbt//0.12.2/sbt.rpm
Latest version sbt-0.13.1:
$ sudo yum localinstall http://repo.scala-sbt.org/scalasbt/sbt-native-packages/org/scala-sbt/sbt/0.13.1/sbt.rpm

Is there any way to know when a crontab was installed on ubuntu server?
Thanks
You can list user's cron tabs:
sudo ls -l /var/spool/cron/crontabs
To see when those files were last changed.
Also, you could read your logs (/var/log/syslog) and search for crontab keyword.
On a default installation of a cron job using crontab -e, the cron get logged in var/log/syslog file.
You can see when a cron job was was installed from that file by running:
grep "END EDIT" /var/log/syslog
The date and time is firt on the line.
Source: https://askubuntu.com/a/56811/147044
try crontab -e . Add 0 0/5 * * * /your/path/to/script/

I have just, in my groggy morning state, reversed & confused the arguments to ln, replacing /usr/share/zoneinfo/America/Toronto with a link to the non-existant /etc/localtime, when I really wanted to link /etc/localtime to Toronto. Now I have no timezone file for where I live. Does anybody have a copy or know where I could get one? It's just instructions on how to translate unix time into toronto time, but I cat'd a few of the other files, and they don't seem like something I'm up to the task of writing by hand.
I know. At least I've never rm -r'd my /
edit:
Before anybody asks, I just tried sudo dpkg-reconfigure tzdata, gleefully entered "America" then "Toronto", only to crash and read, cp: cannot stat '/usr/share/zoneinfo/America/Toronto': no such file or directory. ARGH.
apt-get install --reinstall tzdata
Depending on which GNU/Linux distro you're using, you may be able to just re-download the whole of the tzdata package using its package manager. I know ArchLinux has a package for the time zone data and so does Debian.
However, you can also manually download the whole package and extract the time zone file that you want.
