I have following RDF (Turtle) file, this RDF is generated from CSV file using CSV2RDF conversion process by java language. I need to publish this RDF file on the web using linked data principles. How can i publish this RDF data on the web? thanks

You may want to read the Best Practices document.
Off the top of my head you should tweak your conversion process:
Eliminate some of the blank nodes, so that the data can be retrieved over the web. Hash URIs would be a good choice
file:/// URIs are also no good, because they are meaningless for external consumers
You should include some links to other datasets like DBpedia or Wikidata. The links are what defines Linked Data
Finally, for starters the publishing itself could be as simple as putting your turtle as static content file.

When trying to access an SmbFile with a DFS URL, the jcifs library fails. But when I use the UNC returned by dfsutil it works.
NtlmPasswordAuthentication auth = new NtlmPasswordAuthentication( domain, user, pass );
SmbFile folder = new SmbFile(path,auth);
If path is set to
smb://mydomain.example.com/ourdfs/go/to/my/folder
the call fails with
Exception in thread "main" jcifs.smb.SmbException: The network name cannot be found.
But it is successful when invoked with the resolved name
dfsutil diag viewdfspath \\mydomain.example.com\ourdfs\go\to\my\folder
The DFS Path <\\mydomain.example.com\ourdfs\go\to\my\folder>
resolves to -> <\\someserver.example.com\sharename$\my\folder>
Then the following url works for path
smb://someserver.example.com/sharename$/my/folder
How do I set up jcifs to handle DFS properly i.e. not having to translate urls thru dfsutil?
The solution is to set the WINS configuration. IPCONFIG /ALL will show the information:
Connection-specific DNS Suffix . : MYDOMAIN.EXAMPLE.COM
Description . . . . . . . . . . . : Ethernet Connection
Physical Address. . . . . . . . . : DE-AD-BE-EF-F0-0D
DHCP Enabled. . . . . . . . . . . : Yes
Autoconfiguration Enabled . . . . : Yes
IPv4 Address. . . . . . . . . . . : 10.10.1.42(Preferred)
Subnet Mask . . . . . . . . . . . : 255.0.0.0
Lease Obtained. . . . . . . . . . : December 3, 2018 09:03:04 AM
Lease Expires . . . . . . . . . . : December 9, 2018 09:03:04 AM
Default Gateway . . . . . . . . . : 10.10.1.1
DHCPv4 Class ID . . . . . . . . . : O-mobile
DHCP Server . . . . . . . . . . . : 10.10.11.13
DNS Servers . . . . . . . . . . . : 10.10.4.48
10.10.4.56
Primary WINS Server . . . . . . . : 10.10.1.59
Secondary WINS Server . . . . . . : 10.10.2.58
NetBIOS over Tcpip. . . . . . . . : Enabled
The then configuration item has to be set as follows:
jcifs.netbios.wins=10.10.1.59
or by setting it with jcifs.Config.setProperty()
i need a regular expression to separate left and right part of this pattern . . . . . :
for e.g.
Media State . . . . . . . . . . . : Media disconnected
Connection-specific DNS Suffix . : alumnus.co.in
Description . . . . . . . . . . . : Microsoft ISATAP Adapter
Physical Address. . . . . . . . . : 00-00-00-00-00-00-00-E0
DHCP Enabled. . . . . . . . . . . : No
Autoconfiguration Enabled . . . . : Yes
and store them into two variable.
i have written this regular expression
regexp {([[a-z]*[0-9]*.*[0-9]*[a-z]*]*" "):([[a-z]*[0-9]*.*[0-9]*[a-z]*]*)} 6*rag5hu. . :4ku5-1a543m match a b
but it is not working.
Any help will be appreciated.
I would do this:
set text {Media State . . . . . . . . . . . : Media disconnected
Connection-specific DNS Suffix . : alumnus.co.in
Description . . . . . . . . . . . : Microsoft ISATAP Adapter
Physical Address. . . . . . . . . : 00-00-00-00-00-00-00-E0
DHCP Enabled. . . . . . . . . . . : No
Autoconfiguration Enabled . . . . : Yes}
foreach line [split $text \n] {
if {[regexp {^(.+?)(?: \.)+ : (.+)$} $line -> name value]} {
puts "$name => $value"
}
}
outputs
Media State => Media disconnected
Connection-specific DNS Suffix => alumnus.co.in
Description => Microsoft ISATAP Adapter
Physical Address. => 00-00-00-00-00-00-00-E0
DHCP Enabled. => No
Autoconfiguration Enabled => Yes
This uses a non-greedy quantifier (+?), and that make every quantifier in the regex non-greedy. You then require the anchors so that the bits you want to capture contain all the text you need.
Borrowing the definition of text:
package require textutil
foreach line [split $text \n] {
lassign [::textutil::splitx [string trim $line] {\s*(?:\. )+:\s*}] a b
puts "a: $a\nb: $b"
}
Giving the output
a: Media State
b: Media disconnected
a: Connection-specific DNS Suffix
b: alumnus.co.in
a: Description
b: Microsoft ISATAP Adapter
a: Physical Address
b: 00-00-00-00-00-00-00-E0
a: DHCP Enabled
b: No
a: Autoconfiguration Enabled
b: Yes

I have installed a Jena Fuseki server on OpenShift.
The --config services.ttl configuration file is as shown below.
What I observe is the following:
If I perform a SPARQL update from the Control Panel I get Update Succeeded and some TDB files do change on the server (in ./app-root/data/DB/).
However when I perform a SPARQL query such as SELECT ?s ?p ?o WHERE { ?s ?p ?o. } again in the Control Panel I get zero statements back. This same is true for this GET request:
http://<obfuscated>.rhcloud.com/ds/query?query=SELECT+%3Fs+%3Fp+%3Fo+WHERE+{+%3Fs+%3Fp+%3Fo.+}&output=text&stylesheet=
The log file on OpenShift contains these entries:
INFO [24] GET http://<obfuscated>.rhcloud.com/ds/query?query=SELECT+%3Fs+%3Fp+%3Fo+WHERE+{+%3Fs+%3Fp+%3Fo.+}+&output=text&stylesheet=
INFO [24] Query = SELECT ?s ?p ?o WHERE { ?s ?p ?o. }
INFO [24] exec/select
INFO [24] 200 OK (2 ms)
So it appears as if RDF statements can be written to TDB but not retrieved. If I try the same on a local installation of Fuseki the problem does not manifest.
What else can I do to diagnose and resolve this problem with Fuseki on OpenShift?
UPDATE Apparently the problem does not manifest if I INSERT statements into a named GRAPH (not the default graph).

tdb:unionDefaultGraph true turned out to be the culprit. From the documentation:
An assembler can specify that the default graph for query is the union
of the named graphs. This is done by adding tdb:unionDefaultGraph.
Since this does not mention the default graph as part of the union I guess with this configuration there is no default graph other than the union of the named graph and hence updates that do not name a graph are ignored.
The described problem disappears with the alternative configuration tdb:unionDefaultGraph false.
I need to open exim relay to a list of ips in a mysql database.
I think if I can run a script before a email is queued, I can do that. Is there a way?
Mail Enable for windows has a similar solution called "SMTP Inbound Command Scripting".
# configure
. . . . .
hide mysql_servers = localhost/myoneandonlybase/login/pass
hostlist myfriends = ${lookup mysql{SELECT ipaddr FROM submitters}}
. . . . .
acl_smtp_connect = acl_conn
acl_smtp_rcpt = acl_rcpt
acl_smtp_data = acl_data
. . . . .
begin acl
acl_conn:
accept hosts = +myfriends
. . . . .
acl_rcpt:
accept hosts = +myfriends
. . . . .
acl_data:
accept hosts = +myfriends
. . . . .
The default exim configuration file already has a hostlist relay_from_hosts that you can easily populate with an SQL lookup and get the desired result:
hide mysql_servers = localhost/myoneandonlybase/login/pass
hostlist relay_to_domains = ${lookup mysql{SELECT ipaddr FROM submitters}}
Nothing more than that is needed.

On the three browsers above, the arabic text is well displayed.
On Chrome (V 15) bellow, it's a bit not well organized.
What seems to be the problem ?
PS: i'm using Fusioncharts
EDIT:
That's how I'm writing it:
echo '<set label="' . addslashes($label) . ' - \' + value_' . $i . ' + \'% (' . $label_value . ') " value="' . $data_pie['nb'] . '" />\';' . "\n";
