why unsigned integral type in haskell called "word"? "ord" stand "ordinal"? here documentation on data.word: http://hackage.haskell.org/package/base-4.6.0.1/docs/data-word.html#t:word this hard question google! from wikipedia : the term 'word' used small group of bits handled simultaneously processors of particular architecture. size of word cpu-specific. many different word sizes have been used, including 6-, 8-, 12-, 16-, 18-, 24-, 32-, 36-, 39-, 48-, 60-, , 64-bit. since architectural, size of word set first cpu in family, rather characteristics of later compatible cpu. meanings of terms derived word, such longword, doubleword, quadword, , halfword, vary cpu , os. in short, word fixed-length group of bits cpu can process. work words powers of two, since modern cpus handle well. word in particular not number, although treat such purposes. instead, think of fixed number of bits in ram can manipulate. common use word8

i learning dijkstra's algorithm , had basic query. have graph looks follows..(non-negative nodes): a---2-----b------16------d-----3-------f * * * * 3 4 * * c----------2---------------------------e not clear above graph display, ac has distance of 3 , ef has distance of 4. i interested in finding shortest path between , f. consider destination node f. when consider nearest node, d (df has weight 3 , ef 4). however, when follow path, shortest path as: a,b,d,f (total distance: 19). a quick observation tells shortest path a,c,e,f (distance: 9). however, since in 1st step, e more distant d, followed d. am missing here? dijkstra's algorithm not showing right result here. yes dijkstra's gives shortest path when edge costs positive. however, can fail when there negative edge costs.

people struggle increase seo of websites, same other websites, studying seo training videos, reading blogs seo. but website made school need reverse, want website not listed in of search engines, because website intended used school's staff , students have direct link website. the safest method if want hide website public (world) password protect it, if want disable seo website use following meta tag: <meta name="robots" content="noindex, nofollow"> you can use robots.txt file in site's root containing following content: user-agent: * disallow: / it should noted search engines indexing site whether honor robots.txt ; not obliged to.

i have created uicollectionviewcell looks this #import "photocell.h" @implementation photocell @synthesize imageview; - (instancetype)initwithframe:(cgrect)frame { self = [super initwithframe:frame]; if (self) { self.backgroundcolor = [uicolor clearcolor]; imageview = [[uiimageview alloc] initwithframe:(cgrect){.origin = cgpointmake(4.0f, 4.0f), .size=cgrectinset(frame, 4.0f, 4.0f).size}]; imageview.autoresizingmask = uiviewautoresizingflexiblewidth | uiviewautoresizingflexibleheight; [self.contentview addsubview:imageview]; } return self; } @end i calling 1 of view controllers trying set uicollectionview.. calling class - (uicollectionviewcell *)collectionview:(uicollectionview *)cv cellforitematindexpath:(nsindexpath *)indexpath; { photocell *cell = (photocell *)[self.photocollectionview dequeuereusablecellwithreuseidentifier:@"cell" forindexpath:indexpath]; nsdictionary *currentphotodict

i trying build dynamic google map using jquery json , php, how managed complete map listing using following code example: <script type="text/javascript"> // root path data directory var dataroot = 'gmap-master/'; // data file markers (could php file dynamic markers) var newdate = new date; var markerfile = dataroot + 'ammap.php'; // set default map properties var defaultlatlng = new google.maps.latlng(49.00, 10.00); // zoom level of map var defaultzoom = 2; var ndefaultzoom = 2; // variable map var map; // variable marker info window var infowindow; // list marker check if exist var markerlist = {}; // set error handler jquery ajax requests $.ajaxsetup({"error": function(xmlhttprequest, textstatus, errorthrown) { alert(textstatus + ' / ' + errorthrown + &#
