the following python code: import networkx nx g = nx.digraph() g.add_nodes_from([0, 1]) g.add_edges_from([(0,0), (0,1), (1,0), (1,1)]) nx.write_dot(g, 'g.dot') gl = nx.line_graph(g) nx.write_dot(gl, 'gl.dot') creates following dot format graphs: --- g.dot --- digraph { 0 -> 0; 0 -> 1; 1 -> 0; 1 -> 1; } --- gl.dot --- strict digraph { "(0, 1)" -> "(1, 1)"; "(1, 0)" -> "(0, 0)"; "(0, 0)" -> "(0, 1)"; "(1, 1)" -> "(1, 0)"; } should edges: "(1, 0)" -> "(0, 1)"; "(0, 1)" -> "(1, 0)"; "(0, 0)" -> "(1, 1)"; "(1, 1)" -> "(0, 0)"; be in line graph construction? http://en.wikipedia.org/wiki/line_graph#line_digraph nx.line_graph creates strict digraph. strict means there no loops , no repeated edges.

say have piece of code such as: [myattribute("long long text 1", "some more long text 1")] [myattribute("long long text 2", "some more long text 2")] [myattribute("long long text 3", "some more long text 3")] public class testclass { [...] } is there way introduce consts substitute common substrings in these attributes (i.e. long long text , some more long text in example) ? understand might not possible in terms of actual 'const' surely there must feature ? you can use constants: public class someclass { public const string someconstant = "long long text 1"; } [myattribute(someclass.someconstant)] public class someotherclass { } you have reference them properly.

i'm using open mpi 1.6.5 run openfoam in parallel on 3 nodes. i'm allowed open few tcp ports security reasons. opened ports 49990-50009 open mpi , set values in openmpi-mca-params.conf follows: btl_tcp_port_min_v4=49990 btl_tcp_port_range_v4=10 oob_tcp_static_ports=50000-50009 when ran mpirun, got message: mca_oob_tcp_init: unable create ipv4 listen socket: unable open tcp socket out-of-band communications. did miss something? how can set mpi run range of ports? the value of oob_tcp_static_ports should comma-separated list of specific ports used, not range of ports. set port range tcp oob, assign oob_tcp_dynamic_ports instead. note port numbers (also tcp btl) affect listening sockets, i.e. incoming connections. connection initiator side uses whatever port number os binds socket to. reference - the open mpi user's mailing list .

i'm having little trouble figuring out how make subscription reactive publication query. my publication follows: meteor.publish('alldata', function(){ return data.find({ttl: {$gt: new date()}}) }) as can see, documents contain ttl field. long time live still greater current time, can sent client, if not, shouldn't. the subscription: this.autorun(() => { this.subscribe('alldata') }) on initial load, data fine, whenever ttl expires, document remains on client unless reload page. there anyway handle reactively, making expired documents disappear client? a combination of reactivevar , autorun did trick me. it's possible overkill, works. let cutofftimestamp = new reactivevar(); meteor.setinterval(function() { cutofftimestamp.set(date.now() - 1); }, 60000); meteor.publish("mypub", function() { this.autorun(function() { return mycollection.find({ timestamp: { $gte: cutofftimestamp.get(); } }); })

solved: use fetchall instead of fetch i have simple sql query works in phpmyadmin, in php first row returned. table has lot of rows, since it's cities of world table (around 44.000 rows). function getallcities(){ include 'db.php'; $response = json_decode('{"status":"error"}'); if(isset($_session['user'])) { $query = $conn->prepare("select * cities_countries"); $query->execute(); $result = $query->fetch(pdo::fetch_assoc); $response->status = "success"; $response->cities = $result; } echo json_encode($response); } this gets returned: { status: "success", cities: { id: "1", name: "bombuflat, india" } } as mentioned above, if run query in phpmyadmin, results. what doing wrong? if want output results should use fetchall method
