i need input on idea had. if you're interested/experienced in sqlite , lowest-budget-high-end-solutions (win ;)) you. while fleshing out question have gotten pretty excited idea, bear me. there's tl;dr below i have developed vb.net (3.5) desktop application sqlite. data structured in eav-model, because need flexibility (the semantic structure of data stored separately in xml file). application performs above expectations, - scenario @ hand - large database (about 120mb main file). as expected performance abysmal when sqlite file(s) on network folder. it's bearable have higher goals. expected scenarios (for now) max. 10 users need access database concurrently within local windows network. 98% of concurrence required heavy read-access, inserts , updates sparse , small. the software used exclusively within environments low budget , technical infrastructure (support , hardware) lower, goal avoid using database server. not want implement own sqlite "server" ...

i want create random integer between 1 , 2 (for player1 , player2). if it's 1, player 1 should win first move, , if it's 2, player 2 should win first move. tried this, it's not working: random generator = new random(); int rand = generator.nextint(2) + 1; if(rand == 1){ player1 = true; player2 = false; toast.maketext(getapplicationcontext(), playeronename + " won first move!", toast.length_short); } else { player1 = false; player2 = true; toast.maketext(getapplicationcontext(), playertwoname + " won first move!", toast.length_short); } it doesn't give errors, nothing happens. it's player 1 takes first move, , toast doesn't appear! first notice toast command not complete, , should be: toast.maketext(getapplicationcontext(), playeronename + " won first move!", toast.length_short).show(); then you'll have better on what's

i need show window inside tab of window , using following var childwindoweditor = new mainwindow(); //window embed object content = childwindoweditor.content; //take out content of window embed childwindoweditor.content = null; editortab.content = content; //just tab in tabbed group its working fine, problem if wanted access functions of window class? i know tha should create user control, there solution without having create content of window user control? would casting content window got content work? you should use mvvm pattern. viewmodel datacontext of childwindoweditor . editortab.datacontext = childwindoweditor.datacontext; and that's it. recommend use mvvm . makes life easier.

i have listview until today have positioned 2 views: 1 imageview left of parent, , use textview positioned right of imageview. in xml use following code that: android:layout_torightof="@+id/single" , single imageview. ... no problem whatsoever :-) but today came new idea - want imageview in listview. positioned new view right side of parent (listview). android:layout_alignparentright="true" now small problem arised when did this: in cases have long sentence in textview overlappes new imageview. according android documentation found code: android:layout_tostartof="@+id/volume" , volume id new imageview. i thought work. end of means positions end edge of view start of given anchor view id.

couchdb uses javascript validate, query, map-reduce , on. i'd know there way use node.js library in these javascript functions? such use require('http') or third party modules installed npm . thanks. you can use node.js libraries long don't require node.js-specific libraries http . example, async works in couchdb. rule of thumb: if it's intended server and client, should good. you can use commonjs's module.exports , exports[something] patterns share code between views. check out the documentation more details. for example, consider view: { _id:"_design/test", views: { lib: { test: "exports.guests = 42;" }, fish_per_person: { map: function(doc){ var guests = require('views/lib/test').guests; // 42 emit(doc.number_of_fish, doc.number_of_fish / guests); } } } } the fish_per_person view requires value guests exported in lib/test .

i have feature users can add notes, , every note can have multiple file attachments. when user clicks 'upload attachment', file begins uploading amazon s3 instantly (before users save note). done ajax. what best way (flow) make sure these amazons3 files linked note (when note submitted) or discarded if note isn't saved? i can think of 2 approaches: go ahead , save note, have column on model tells whether or not it's temporary. if user clicks save, change column temporary permanent. run rake task in background clear out temporary notes more day old, etc., if wanted that. put sort of reference in image's file name. can't use id, since won't exist yet, may have other unique identifiers such combination of username , post title. if can 1st option, i'd preferable. gives unique id note, has express purpose of making possible reference note externally.

ok guys. more of "can done?" question opposed "how do this?" i have wcf project multiple services , lining fine. 2 of them wrapped in windows service installers go on 2 different servers. possible call method in 1 service other service if on 2 separate machines? or have use callback scenario have seen used before? i appreciate advice or ideas. thanks. this depends on binding using , firewall / network route rules on , between 2 machines. if using namedpipebinding, answer no because named pipes bound machine. however, if using of other bindings webhttp, basichttp, etc should ok. beauty of wcf should able spin service endpoint using different binding if necessary -- if using named pipes, should pretty straight forward swap out different binding. a wcf service can client wcf service.

the async-await pattern of .net 4.5 paradigm changing. it's true. i've been porting io-heavy code async-await because blocking thing of past. quite few people comparing async-await zombie infestation , found rather accurate. async code likes other async code (you need async function in order await on async function). more , more functions become async , keeps growing in codebase. changing functions async repetitive , unimaginative work. throw async keyword in declaration, wrap return value task<> , you're pretty done. it's rather unsettling how easy whole process is, , pretty text-replacing script automate of "porting" me. and question.. if code turning async, why not make async default? the obvious reason assume performance. async-await has overhead , code doesn't need async, preferably shouldn't. if performance sole problem, surely clever optimizations can remove overhead automatically when it's not needed. i've read ...

i'm trying multisort db array based on users status. status = 1 go @ top, status = 0 go @ bottom of array. thought had working stopped today addition of new rows db. uasort($ven, function ($a, $b) { return $a['v_status'] == '1' ? false : true; }); it's simple db array mysql: array ( [0] => array( [name] => '', [v_status] => 0 [1] => array( [name] => '', [v_status] => 1 ) as mentioned in comments other answer, splitting array active/inactive arrays better solution sorting. $items = array( array('name' => 'active1', 'active' => '1'), array('name' => 'inactive1', 'active' => '0'), array('name' => 'active2', 'active' => '1'), array('name' => 'inactive2', 'active' => '0'), array('name' => 'inactive3', 'activ...

i want following calculation without losing precision in c. uint64_t ts_1 = 0x5212cb03ca115ac0; uint64_t ts_2 = 0x5212cb03ca115cc0; uint64_t ts_delta = (ts_2 - ts_1) double scale_factor = ts_delta/(2^32) i getting value of ts_delta 0x200. value of scale_factor 15.000000 .basically losing precision during calculation. how do without losing precision.? here short self contained example on how trying print. #include <stdio.h> #include <stdint.h> #include <inttypes.h> int main() { uint64_t ts_1 = 0x5212cb03ca115ac0; uint64_t ts_2 = 0x5212cb03ca115cc0; uint64_t ts_delta = (ts_2 - ts_1); double scale_factor = ((double)ts_delta) / (((uint64_t)1) << 32); printf("ts_delta %"prix64" scale factor %f \n",ts_delta,scale_factor); return 0; } you're not doing calculation think you're doing. ^ operator in c not perform exponentiation, performs bitwise exclusive or. divi...

similar, not quite one: force browser save file after clicking link i don't want make file download rather render (the end doing "content-disposition: attachment" header. want our internal website users click link , dialog lets them choose directory load file to. this, opposed natural state of things non-right-click downloads directly users' downloads folder. if understood correctly , without plugins, think impossible. way can require verify browser , browser chrome (due spec http://dev.w3.org/2009/dap/file-system/file-dir-sys.html ) can that.

i know each port can assigned 1 app. however, want this: (1) want monitor port, such 80. port assigned app, such apache (2) can copy every sockets sent port, , redirect ports port i have searched tcpdump, can capture packets(with whole content). not how copy packets , send them port? or, maybe there other tools can capture packet easily? can give me details if want implement myself? because not @ socket programming. as correctly noted, not able use socket packets port 80 easily. because if second socket receive packets port, need reuse port (so_reuseaddr option). if application third-party , cannot set option server socket, not work. probbaly try checking out scapy has option of sniffing packets , see if meets our requirement: http://www.secdev.org/projects/scapy/doc/usage.html .

sorry being javascript noob, can please explain why recommended not use .innerhtml . when have faster , easier in form of .innerhtml , why shouldn't use ? innerhtml sledgehammer. blast away contents of selected dom element , replace them whatever happens assigned @ time. leads number of html escaping , validation issues. more importantly, pages large number of events bound, using innerhtml append element regenerate dom elements, means event bindings can lost. there issues regarding memory leaks in older versions of ie when elements removed dom. with of said, i'm not telling you shouldn't using innerhtml . use time in jquery when use $(selector).html() . sledgehammer right tool job, , when events delegated won't matter how content reloaded.
