i have application there list of items users page through. have handled paging through index field (i needed other things eitherway figured why not). my issue want implement "goto" feature; user can skip directly item instead of paging through them using provided navigation buttons (next , previous). instance, can enter 1000 in "goto" box , have 1000th item displayed. there disconnect between nth item , index - index guaranteed in order not guaranteed sequential can't filter index. thought using offset parameter of fetch , remember when first started programming using appengine told not use due performance issues. would offset best way go here, or there better way? also, costs associated take longer results, or count towards datastore reads/small operations? edit: don't mean in bad way in order stave off people tell me use cursors... :-) handle paging in way more useful me if use cursors. thank in advance concern. additionally, thought i'd spell o...

for number of uninteresting reasons: need copy many classes 1 project (while preserving package-structure of said classes). in other words, given: origin/src/com/foo/bar/a origin/src/com/baz/qux/b dest/ <empty> we want copy , b such end with: dest/src/com/foo/bar/a dest/src/com/baz/qux/b presently, forced manually create packages in dest , ctrl+c/ctrl+v individual .java files between projects. have eclipse automatically copy files on while automatically creating packages (hence, preserving package structure). you can copy files between project folders using shell script. eclipse pick copied java files including package structure. if select files in source project in navigator window panel (not package explorer) should able ctrl+c/v whole file structure preserving packages new project.

you can embed svg file into (x)html 5 document: <object data="anim.svg" id="svganim"/> or <img src="anim.svg" alt="embedded svg"/> but if anim.svg animated, animation start playing page loads. how can embed animated svg file such animation starts out paused? user can play animation pressing button (using unpauseanimations() in javascript) an inelegant way window.onload = function() { var svg_anim = document.getelementbyid('svganim').contentdocument.rootelement; svg_anim.pauseanimations(); }; disadvantage: doesn't work if embedded svg in different security context parent document. there better way? one way solve make animations not start automatically changing svg file (to add begin="indefinite" animations start automatically). these animations can triggered call beginelement() animation elements want trigger. if have many such elements, it's easier use pauseanimations() . however, <img...

i'm little confused on how captive portal authentication works. in implementations, after user authenticated login page, ip , mac address whitelisted , allowed connect through gateway. has problem of people spoofing mac addresses gain access. if portal sets session between , client, mean every piece of traffic client requests internet must go through portal's server? generally, security in captive portal not considered particularly important. however, there solutions lock mac first port use , disallow use of mac on additional port. similar techniques can used wirelessly, ap refuse pair additional client using same mac address existing client. requires enterprise authentication unique key negotiated each attached device. it's not clear me mean "the portal's server". generally, once mac address authorized , wired port configured or wireless connection established, nothing further needs done portal. traffic authenticated connections routed/natted normally. ...

i need access contents of char* casting array here's demo: from ctypes import * foo = (c_char * 4)() foo.value = "foo" print foo.raw # => 'foo\x00' foo_ptr = cast(foo, c_char_p) print foo_ptr.value # => 'foo' now want convert foo_ptr (c_char * 4). neither of these work foo_ = (c_char * 4)(foo_ptr) foo_ = cast(foo_ptr, c_char * 4) found it foo_ = (c_char * 4).from_address(foo_ptr._get_buffer_value()) print foo_.raw # => 'foo\x00'

i facing problem calling function on click. following code: javascript: $(document).ready(function(){ function showmessage(msg) { alert(msg); }; }) html: <input type="button" value="ahaha" onclick="$(this).showmessage('msg');" /> for reasons cant use click() function. please me. a few things: showmessage() isn't property of jquery object. it's regular function. if you're using jquery, don't use onclick . bind events javascript. there few ways of fixing code. here's one: javascript : $.fn.showmessage = function(message) { alert(message); }; $(document).ready(function() { $('#button').on('click', function() { $(this).showmessage('i message'); }); }); html : <input type="button" value="ahaha" id="button" />
