[Rdkit-discuss] RDKit and the 2017 Google Summer of Code

[Greg Landrum]

Dear all,

The "OpenChemistry" organization has once again been selected to be a
mentoring organization for the Google Summer of Code:
https://summerofcode.withgoogle.com/organizations/6519372857212928/

I'm really happy to share that the RDKit will be part of the program this
year (many thanks to Geoff and Adam for the invite). This is a great chance
to get some students involved in RDKit coding by having Google pay them to
work with us on a project for the summer. Now we just need to find the
students; I'm hoping that the community can help here.

There are a list of project ideas here:
http://wiki.openchemistry.org/GSoC_Ideas_2017
but it's perfectly ok for students to propose their own ideas.

Here's the description of the program:
https://summerofcode.withgoogle.com/how-it-works/

If know of any students (or are one!) who are interested in working on one
of the listed projects list or who have other project ideas, please get in
touch with me

Feel free to forward this message and/or put interested students directly
in contact with me.

Best,
-greg

 Maybe this one here helps, too, although it is basically the same what TJ said:

The server itself must be told to allow remote connections.
You might check these two things.
1.  You can edit the postgresql.conf file (not sure where that is on your 
system).
 https://www.postgresql.org/ docs/9.2/static/runtime- config-connection.html
 Uncomment or add the line listen_addresses='*'. You can
 tailor that to be more specific, but try this first.
 
2.  The file pg_hba.conf also controls access.  Look at this:
      https://www.postgresql.org/ docs/9.3/static/auth-pg-hba- conf.html

Be sure to restart the server after you make changes to these files.

Hope this helps,
TJ O'Donnell

Hi,I've installed rdkit on a CentOS machine using anaconda python and set up a 
postgresql compound database in the rdkit environment. It works great on the 
machine's console.I now want to access it remotely and I'm trying to set up a 
jdbc postgres driver to access it from a windows client but this is not 
working. If I test the driver on the server it tells me that the connection is 
refused and I should check that the machine is accepting TCP requests.
I have opened the standard port that postgres uses
-A INPUT -m state --state NEW -m tcp -p tcp --dport 5432 -j ACCEPT
iptables -L returnsACCEPT tcp  --  anywhere anywhere    
state NEW tcp dpt:postgres 

this is where I don't know what to check next. A few things that might be 
relevant. If I "ps -eaf | grep post" I see four postgres processes running 
under my username (not postgres), so I think there is a server working. There 
is also a "system" postgresql (version 9.2) which I have connected to 
previously a long time ago. This connection no longer works either and I don't 
really care about that but could be an interfering factor.
If anyone has suggestions about what to check next or solve this I'd be grateful

thanks,Neil
