how fix hash table chaining when items hash same slot (one giant linkedlist)? does hash table chaining uses table doubling? if when time double size of table. expanding on answer nikic's comments: for first question, unfortunately real possibility when implementing chained hash table. assuming have hash function - or, better yet, choosing hash function involves element of randomness - extremely unlikely. unfortunately, bad people use take down web servers. not long ago, attack called "hash dos" developed whereby craft bunch of specialized requests web server cause stored in same slot in chained hash table, led huge performance drops , took websites offline. news, though, many programming language implementations have been updated hash tables aren't vulnerable things this. for second question, answer "it depends." implementations of chained hash tables rehash , grow when load factor gets high (usually, load factors between 1 , 2 common). i...

i struggling correct syntax iterating through array pass properties (and number of items) external js constructor function. the syntax constructor is: `swal.withform({ formfields: [ { id: 'x', type:'y', name:'z', value:''}, {etc...} ] })` but let's number of formfields dynamic, , stored in array. how can iterate through inside constructor function? or there way "paste" externally created syntax function? hope question makes sense. do mean want populate formfields array dynamic data? if should it. var myfields = []; myfields.push({ id: 'x1', type:'y', name:'z', value:''}); myfields.push({ id: 'x2', type:'y', name:'z', value:''}); myfields.push({ id: 'x3', type:'y', name:'z', value:''}); swal.withform({ formfields: myfields }) you build array using loop or map function if have array need convert f...

i released net::nscang::client while ago , getting lot of test failures on openbsd. reason nscang protocol uses openssl in preshared-key mode (rfc4279), folks @ libressl (default on openbsd now) have ripped out. however, seem have been hell-bent on doing intransparent way: include files have functions defined, shared library missing corresponding symbols, compilation works fine tests fail. there compatibility package on openbsd called eopenssl, , testing first in makefile.pl (using extutils::pkgconfig ) can make work if compatibility library installed. if isn't, things still fail. i check cpp symbol openssl_no_psk, includes come libressl, fails if linking eopenssl work fine. idea have left try , have test program run part of compilation phase autoconf it. possible extutils::makemaker (or else -- wouldn't mind switching build system if necessary)? it's easy write feature tests devel::checklib . following can used check presence of function your_func (in ...
