i've got nodes represent maven artifacts, e.g.: create (n:module {artifactid:"com.my.test", version:"1.0.0"}) return n.artifactid, n.version; someone got idea how query nodes in range of e.g. [1.0.0, 2.0.0]? split version 3 properties version_major, version_minor, version_micro, if results in easier query. if storing version string can rely on lexicographical sort order query: match (n:module) n.version >= "1.0.0" , n.version <= "2.0.0" return n

i have node socket server running on same vps website is. there way can prevent other "websites" or other node projects connecting socket server , emitting data? my website , node project have same ip address. for example: (client side html) <script> var socket = io.connect('localhost') //localhost example socket.on('example', function(data) { console.log(data) ; }); socket.emit('sendtoserver', 'hello world'); </script> i want code right here usable website (or ip) edit: if there isnt within socket.io, there way can authenticate socket server make ip can emit things if you're concerned it, should consider allowing authenticated users. otherwise trying ban explicit ip addresses , maintaining list isn't feasible.

i solving question on hackerrank. following question (in brief): there exist n robbers trying rob bank. can stay there atmost g minutes. 2 robbers can enter vault @ time. a[]={a_1,a_2,...,a_n} is user specified array such that a_i is time the i_th robber wishes stay in vault. a heist successful if robbers wish. given n,g, a[]; the output must "success" or "failure". my logic follows: sort(a) in descending order define slot1 , slot2 1st , 2nd person in vault respectively slot1=slot2=g fill in slot1 , slot2 sorted a, such whenever robber finished in slot, next 1 takes place if robbers can accommodated, success, else failure. i try having double pass. first, add time robbers want, halve , round up. that's ideal time. (at point, check if 1 of robbers at/over amount; if so, that's limit.) then, try fit robbers time frame. if can fit them evenly, you're good. otherwise, increase time , try again.

in debug, code works fine. when release apk proguard 5, proguard offuscate variables, , when try "jsonify", resulting string offuscated, , so, php script doesn't understand anything. here's code: arraylist lcapturas=...; if (lcapturas != null) { gson gson = new gson(); type listofcapturaobject = new typetoken<list<captura>>() { }.gettype(); json = gson.tojson(lcapturas, listofcapturaobject); } and json string [{"j":"2014-09-10 17:35:25","e":"2014-09- 10","f":"19.3641107,-99.1785061","d":28809,"c":85,"b":2705,"a":1,"l":1,"m":0}] i guess must proguard not offuscate captura objects. there way of disabling option? or how should do??? i resolved issue : -keep class com.pkg.vo.myclass { *; } for each class need keep variable names. stackoverflow didn't

i have std::multiset, stores std::pair. want first attribute have no constraint on uniqueness, want second 1 unique. so, decided pass own function multiset, in order achieve (if not please let me know). based on this answer, wrote similar function fails, , have no idea why (no idea of λ - , greek :) ). auto f = [](std::pair<float, int>& a, std::pair<float, int>& b) { return (a.first < b.first && a.second != b.second); }; error: error: expression ‘#‘lambda_expr’ not supported dump_expr#<expression error>’ not constant-expression sorry, unimplemented: non-static data member initializers error: unable deduce ‘auto’ ‘<expression error>’ i think cannot pass lambda (runtime construct) template parameter (compile-time construct). using struct operator() works instead: #include <set> struct my_compare { bool operator() (const std::pair<float, int>& a, const std::pair<float, int>& b) { return (

i work solution has lot of projects in it. created new build configuration speed working it. to speed compiling, set of projects not build in new build configuration. speed debugging, set of projects build release in new build configuration. this great, until have check in change project file, or latest else's changes project file. painful merge changes, or shelve , unshelve them constantly. is possible store build configuration in separate file? ideas workarounds welcome. to answer question directly: no cannot store config in seperate file. unless seperate files solution file of course. there workarounds, stored locally on machine (too long comment i'm posting answer anyway): i set of projects not build in new build configuration just build them once, unload projects not built again. these settings stored in .suo file. if insist on keeping seperate build configuration: ask team if it's ok push source control, maybe others can benefit well? or writ

imagine client , service application registered in windows azure. the client console , runs unattended on-premise (e.g. performing tests overnight) service webapi service protected oauth , accessed using openid connect, hosted in azure. how can client authenticate service without sort of user login interaction (i.e. app authenticates service using adal .net)? i tried adal .net daemon webapi sample still pops authentication dialog... thanks! [ edit ] here's code show very how communicate client. app ids etc. correct. var authcontext = new authenticationcontext("https://login.windows.net/common"); var result = await authcontext.acquiretokenasync(serviceappid, clientcredential); var client = new httpclient { baseaddress = new uri("https://localhost:44301/"), }; client.defaultrequestheaders.authorization = new authenticationheadervalue( authenticationheaderscheme.bearer, result.accesstoken); var response = await client.g

i need write several floats file using format() method. want round floats given number of decimal places and write them aligned @ same time. here's mwe: a = 546.35642 b = 6785.35416 c = 12.5235 d = 13.643241 line = [str('{:.2f}'.format(a)), str('{:.4f}'.format(b)), str('{:.5f}'.format(c)), str('{:.3f}'.format(d))] open('format_test.dat', "a") f_out: f_out.write('''{:>10} {:>15} {:>16} {:>15}'''.format(*line)) f_out.write('\n') this gets job done seems awfully convoluted me. there better way using format() ? you can add .#f in format alignment. with open('format_test.dat', "a") f_out: f_out.write('''{:>10.2f} {:>15.4f} {:>16.5f} {:>15.3f}'''.format(a, b, c, d)) f_out.write('\n')
