a co-worker told me when visit website on ssl certificate no longer guarantees you're dealing intended recipient. due called "multi-domain ssl certificates". quick google search seems show these exist - under impression ssl provided encryption and authentication. no longer case? surely step in wrong direction? there wildcard certificates, allow hosts in 1 domain covered same cert. they're more expensive issued (since cas wouldn't make money if you'd ordered multiple separate single-domain certs), when need cover multiple hostnames in domain ssl, can quite savings. a issued cert cover @ least 1 host name, www.example.com. , wildcarding, can cover *.example.com. ssl guarantees nothing in way of identification - link encrypted. certificate - self-signed ones. "commercial" certs (theoretically) trustworthy third party saying "we've verified person www.example.com certificate issused www.example.com"

i still quite new php/ajax/mysql. in anycase, i'm creating search function returning data i'm looking for. in brief, have mysql database set up. php website has search function. i'm trying add link mysql database search rather showing results. in search.php, echo line working fine $string .= not returning anything. i'm trying same echo link mysql php record. missing simple? //echo $query; $result = mysqli_query($link, $query); $string = ''; if($result) { if(mysqli_affected_rows($link)!=0) { while($row = mysqli_fetch_array($result,mysqli_assoc)) { echo '<p> <b>'.$row['title'].'</b> '.$row['post_id'].'</p>'; $string .= "<p><a href='set-detail.php?recordid=".$row->post_id."'>".$row->title."</a></p>"; } } else { echo 'no results :"'.$_get['keyword'].

i'm trying use function count number of unique cells in spreadsheet that, @ same time, meet multiple criteria. given following example: a b c quant store# product 1 75012 banana 5 orange 6 56089 orange 3 89247 orange 7 45321 orange 2 apple 4 45321 apple in example above, need know how many unique stores valid store# have received oranges or apples. in case above, result should 3 (stores 56089, 89247 , 45321). this how started try solving problem: =sum(if(frequency(b2:b9,b2:b9)>0,1)) the above formula yield number of unique stores valid store#, not ones have received oranges or apples. how can add criteria? mine done different way (and works), main reason posting because wondering if second part of formula somehow made array formula making shorter. to this, sort 3 columns on column b smallest largest , since part of array formula, type in formula , [ctrl]+[shift]

i'm using cleditor website i'm working on. i'm trying add dynamic text textarea jquery. i'll using like: $('#mytext').val('here dynamic text'); but doesn't work cleditor. when disabling cleditor works fine however, enabling again text disappears. tried looking on website solution, can't find any. had same problem lately? thanks in advance. $("#input").cleditor({width:500, height:250,updatetextarea:function (){....}})

i assume there's no way so, if had to, how implement set operations on appengine's datastore? for example given 2 collections of integers, how store them in datastore performance intersect , except (all items in not in b) operations? there aren't built in set operations in datastore api. see having 2 options: for smallish sets (hundreds of items) might away doing keys-only queries both set , set b, , doing intersection in application code. precise definition of "smallish" depend on application. for largish sets (millions of items) if know ahead of time intersections you'll want, can calculate them each time insert new record. example, assume have 2 sets , b, , know you'll want query on (a intersects b). whenever insert a, check see if in b. if is, record fact somewhere (either in separate entity type, or boolean property on or b itself). of course, you'll need b's also. with option 1, can have lots of different sets, l

in swing application, when remove jogl glcanvas main component add jpanel @ same place, there display glitches: during time when old component has been removed , before new 1 has been added, remanent images of popup menus have been displayed before on top of glcanvas visible on background of main component. how can avoid this? when adding/removing components visible gui code should like: panel.remove(...); panel.add(...); panel.revalidate(); panel.repaint(); also, the code should execute on event dispatch thread . if code executed within listener on edt. if code executed outside of listener need use swingworker or swingutilities.invokelater().

my need simple. given windows directory path want actual path. sure terminology wrong, giving example. given c:\documents , settings\all users method should display: c:\programdata on windows 7 c:\documents , settings\all users on windows 2003 this because on windows 7 c:\documents , settings junction referencing c:\users , c:\users\all users yet junction referencing c:\programdata , actual directory. so, question .net api lets me this? thanks. check out this code sample has figured out already. essentially, have use win32 function deviceiocontrol via p/invoke passing fsctl_get_reparse_point dwiocontrolcode parameter. as guy on codeproject says... i find interesting .net framework's fileattributes enumeration includes value fileattributes.reparsepoint there no other built-in support reparse points. there no "native" .net api this, bear in mind of framework wrapper around p/invoke calls anyway, shouldn't fear th

background a developer on team has implemented application reviewing. has used interfaces everywhere. app has typical service layer, data layer , poco objects passed website down db. assumption ioc used (through unity) inject runtime concrete service , data class. pocos have nothing , set methods on public properties. question i understand why interface used @ service , data layer why use interfaces on poco objects? overkill? do poco interfaces serve purpose? if yes, may not overkill. however, if not used, violate yagni principle. however, on more general note, i'm beginning think properties on interfaces design smells , violate law of demeter . i posted some thoughts on better abstractions .

how select reading being handled on linux systems in case process forked after opening udp socket? - possible in kind of program: so = open socket fork for(;;) { select() reading on socket recv } two packets wake 1 of processes (in case arrive before waiting process notified / exits select) , second 1 of packets not received? or can assume udp, every packet wake process or leave flag set? each processes, parent , child, has fie descriptor same socket. per file descriptor attributes independent (e.g. blocking, being able close socket). in scenario indeed feasible legal 1 of processes, example waken , read data socket before other 1 getting select.

laurent of mvvm light fame introduced me mvvm, , convention of 1 view has 1 view model. rule of thumb user controls? 1 viewmodel each user control? when creating view leveraging more 1 user control, create viewmodel aggregate user control view models? thanks in advance input. richard in mvvm projects have tended suggest: 1 viewmodel per usercontrol viewmodel aggregates these together. that aggregating viewmodel viewmodel window rather usercontrol - though isn't necessary , may more result of preferences , history , fact work in wpf. the 1 place don't have seperate viewmodel usercontrol create specific reusable usercontrols - things buttons specific visual effects, or custom sliders. that reflected in project structure - have 2 standard folders usercontrols (which not have viewmodels) , views either windows or usercontrols, , have viewmodels.
