how make app icon enabled in actionbarsherlock (not title icon) in whats app. the title clickable icon since android 4.2.2. whatsapp uses custom view display 2 line title. disables title click along way. can same way: actionbar actionbar = getsupportactionbar(); actionbar.setdisplayhomeasupenabled(true); actionbar.setdisplayshowtitleenabled(false); actionbar.setdisplayshowcustomenabled(true); actionbar.setcustomview(r.layout.ab_title); textview title = (textview) findviewbyid(android.r.id.text1); title.settext("title"); /res/layout/ab_title.xml: <textview xmlns:android="http://schemas.android.com/apk/res/android" android:id="@android:id/text1" style="@style/textappearance.sherlock.widget.actionbar.title" android:layout_width="match_parent" android:layout_height="match_parent" android:ellipsize="end" android:gravity="center_vertical" />

i'm looking query string better search results. at moment use operator like select title table lower(column) '%data%' but results not accurate enough. my "search engine" looking events, news , webcontent on website, want results 'data' word 'big-data' , 'big data.' , 'all data' , no results 'maxdata' , 'bigdata' , 'datapool' . can use regexp_like ? select title table regexp_like(column, '(\w|^)data(\w|$)', 'i')

i testing ruby, python , scala see 1 has better support huge arrays. ruby (each) -> 84 mb, 2s # = [];(0...1e7).each{|i| a[i]=i} ruby (expand) -> 254 mb, 60s #a = [*(0...1e7)] python (numpy) -> 95 mb, < 1s # = np.arange(0, 1e7) python (range) -> 391 mb, < 1s # = list(range(0, int(1e7))) scala (range) -> memory limit exceeded :-) # var = range(0, 1e7.toint).map(_.toint) as can see, memory limit exceeds when using scala, what's problem?!!! --update ok should've used var = array.range(0, 1e7.toint) but, if want map array strings? var b = a.map(_.tostring()) failure here... scala's range isn't identical array in pure sense (inside doing additional work besides keeping n items, less memory efficient , eats memory faster). array.range(0, 1e7.toint) closer python's np.arange , work fine.

i wondering if give me advice on how add impulsive , gamma noise image separately? it's easy imnoise function of matlab, i'm not allowed use imnoise, our ta said can use rand function. i came across code seems doesn't work should(for impulse noise): noisyimage=originalimage+255*rand(size(originalimage)); there's few issues line of code: if image rgb (e.g., loaded colour jpeg or something), you'll have add 3 layers of noise; e.g., use rand([size(originalimage) 3]) 255*rand() generates double-valued numbers, whereas image of type uint8 or (check class(originalimage) ). fix, use randi instance: noisyimage = randi(255, [size(originalimage) 3], class(originalimage)); you add noise of maximum magnitude 255 all pixels. might overflow many of pixels (that is, assigned values higher 255). avoid, use noisyimage = min(255, originalimage + randi(...) ); the noise direction positive . true noise brings down values of pixels. so, use noi

ploti'm new d3 , new javascript (most of experience python). went trough tutorial in book interactive data visualization: web scott murray on creating bar chart. didn't have nay issues completing tutorial, approach takes in book seems procedural using global variables. create similar chart, use object-oriented approach able encapsulate variables , reuse code generate multiple charts in 1 script without having repeat code on , on again. i've tried far without luck: function d3chart(id, data, width, height, padding) { this.id = id this.data = data this.width = width this.height = height this.padding = padding this.svg = d3.select("body") .append("svg") .attr("width", width) .attr("height", height) .attr("class", "chart") .attr("id". this.id);

i have application upgrading ravendb 1 ravendb 2. application not store domain object in database directly. instead, domain objects converted document objects prior persistance (and vice versa when reading). example, domain object: public class user { public string id { get; private set; } public string email { get; set; } public string passwordsalt { get; private set; } public string passwordhash { get; private set; } public void changepassword(string oldpassword, string newpassword) { ... } . . . } and corresponing document object (which gets stored in database): class userdocument { public static userdocument fromentity(user user) { ... } public string id { get; set; } public string email { get; set; } public string passwordsalt { get; set; } public string passwordhash { get; set; } public user toentity() { ... } } so, if want change user document stored in database, typically

i'm writing system dropout field borders form image. fields may have writing in them need correctly keep if handwriting crosses field border. i have 2 images: 1 color image (converted hsv colorspace) , 1 black/white image line pixel per pixel (these produced scanner) i remove (pluck) field border pixels black , white image, given colors in color image. i have advantage in know apriori exact location of field, , widths/heights of field border lines. my current implementation consists of (for each field), scanning field border on color image , calculating average hsv value field border (since know field border is, visit "field border" pixels, may visit few handwriting pixels if cross field border, idea won't skew average much). once have "average" hsv value field border, scan field border again, , each pixel compute following delta function: if delta value between "current" pixel , average hsv less 0.07 (found empirically) set pixe

i trying implement dijkstra algorithm. foreach distance d d = infinity d[source] = 0 create_heap_based_on_distances(); while(true) bestedge = heap[0] remove_minimum_from_heap //it heap[0] foreach adjacency of bestedge if (weight + bestedge_distance < current_distance) { current_distance = weight + bestedge_distance // have update heap, how can that? } if (heap_empty) break so, in relaxation, how can update heap, have correct order? don't have heap's index node in step. mean have create new array nodes[edge] = heapindex , heap's index node? seems inefficient need update insert_to_heap , remove_minimum functions. c or java code okay. does mean have create new array nodes[edge] = heapindex, heap's index node? yes. but seems inefficient need update insert_to_heap, remove_minimum functions. array updates cheap, both in theory , in practice, , have few of per heap operation, not
