i trying create gradient effect on half of image, found gives full gradient overlay effect on image .tinted-image { background: /* top, transparent red */ rgba(255, 0, 0, 0.25), /* bottom, image */ url(image.jpg); } but wondering how can apply effect half of image,i searched online didnt see ws looking for, decided post. by half of image mean vertically not horizontally us there has idea of this multiple backgrounds , suitable color stop in gradient. .tinted-image { width: 460px; height: 300px; border: 1px solid grey; background-image: linear-gradient(to bottom, rgba(0, 255, 0, 0.5), rgba(0, 255, 0, 0) 50%, transparent 50%), url(http://www.fillmurray.com/460/300); margin: auto; } <div class="tinted-image"></div>

edit "please focus answer example below, no broad scenarios" ok. have read word cloud. wondering how can represent words occuring in string variable in example below?: var_x wireless problems, migration competitor dissatisfied customers, technicians visits scheduled call waiting, technicians visits bad customer experience, wireless problems so want is: ("wireless problems" , "technicians visits") representation in cloud. how can done? this code produces frequency distribution of adjacent words can used underlying word cloud data: from nltk import bigrams, freqdist nltk.tokenize import regexptokenizer operator import itemgetter sent = 'wireless problems, migration competitor\n\ dissatisfied customers, technicians visits scheduled\n\ call waiting, technicians visits\n\ bad customer experience, wireless problems' tokenizer = regexptokenizer(r'\w+') sent_words = tokenizer.tokenize(sent) freq_dist = freqdist(bigrams(sent_w

i writing simple formula =if(g295="#n/a","na","somethingelse") but it's not printing 'na' when give value "#n/a" if use above formula =if(g295="r","na","somethingelse") then it's working. can me how reconize value "#n/a"? need write formular if value (#n/a) presents, have other operation, there way this? the isna function identify #n/a =if(isna(g295),"na","somethingelse") unlike iserror , catches #n/a

a colleague of mines encountered problem while working on cobol program , solved @ application level. still curious if possible solve on data access level, sql. somehow related this other question , i'd use ansi sql. i'm looking single sql select query acts on varchar field contains variable length csv rows. purpose of query split every csv field in own result set row. here example schema , data (and here fiddle ): create table table1 (`field` varchar(100)); insert table1 (`field`) values ('hello,world,!') , ('haloa,!') , ('have,a,nice,day,!'); here output i'd have query: hello world ! haloa ! have nice day ! the csv separator used comma, , wouldn't worry escaping. as far can tell, ansi sql: with recursive word_list (field, word, rest, field_id, level) ( select field, substring(field 1 position(',' in field) - 1) word, s

i have float column, call money. i trying insert 0 value 0 , empty string value should null insert t1 (money) values ('0.00') insert t1 (money) values ('') select * t1 this result trying achieve money 0 null i tried using instead of insert trigger (i used '123' visualize condition met) iif(cast(money nvarchar) = '', null, iif(money < '0.0001', '123', money)) select * t1 money 123 123 so seems cannot compare float column against empty string. but when trying following looks in fact possible: case when (money = '' '456' else iif(money < '0.0001', '123', money)) select * t1 money 456 456 which makes me unsure of how sql server converts datatypes internally. uhm, you try wierd things if insert string values float-column. insert t1 (money) values (nullif('0.00', '')) but should invest time in data type conversion ground up. expect calli

is there way force use of -flags when reading in command-line arguments using getopt::long? example in current situation: getoptions('r=s' => \$var1, 'lf=f' => \$var2, 'uf=f' => \$var3, 'trd=i' => \$var4, 'vd=f' => \$var5) or die("$usage"); the script not exit or display $usage if arguments still provided without flags (such -lf). instead runs regardless until inevitably errors later on arguments not read respective variables (and may in wrong order). q: getoptions not return false result when option not supplied a: that's why they're called 'options'. source: getopt::long documentation you add conditionals check value of flags , if not defined call die or call usage .

change html content of <p> element id="demo" : document.getelementbyid("demo").innerhtml = "paragraph changed!"; is right way change html content? if want change contents use document.getelementbyid("demo").innertext = "paragraph changed!"; or want change html tags use, document.getelementbyid("demo").innerhtml = "<h2>heading changed!</h2>"; another method document.getelementbyid("demo").firstchild.nodevalue = "paragraph changed!";

i guess start example code: var sentence = 'lorem ipsum dolor sit amet, consectetuer adipiscing elit.'; // makes array single chars of sentence elements. sentence = sentence.split(''); // makes multi-dimensional array. var result = sentence.map(function(ch) { // using /./ leads multi-dimensional array too. // each array contains 2 empty strings elements. // => ["", ""] return ch.split(/. /); }); result.foreach(function(item, i) { console.log(item); // [ ["l"], ["o"], ["r"] ... ] }); the purpose clear me: it's making multi-dimensional array. each element got 1 char of sentence. what don't understand regular expression used. . stands 1 arbitrary character in regular expressions. what's purpose of blank after dot ( . ) ? moreover: if rid of blank , write /./ results arrays too. each array contains 2 empty strings ( "" ) . that behaviour isn't clear me too.

i need create routine gets data http service, , populates <form> , automatically calls submit() on generated form: <form target="_top" #paymentform action="{{payment?.url}}" method="post"> <input *ngfor="let d of payment?.data | keys" name="{{d}}" value= {{payment.data[d]}}> </form> to populate form request returns payment object, containing url , form data posted: this.globalsservice.placeorder(this.globalsservice.shoppingcart) .subscribe(res => { this.payment = res; this.paymentform.nativeelement.submit() }); even though code executes , data loaded form properly, @ moment submit() action executed form not yet populated, , therefore redirect wrong , values mmissing. i looking elegant solution not involve settimeout, redirecting route or using lifecycle hooks.

i trying validate phone number below condition, if 10 digits of same number,it should display error message. if starts 1, should display error message. please share suggestion if have come across such scenario. without example code, hard see trying - , if have attempted @ solving yourself. but oh well, there multiple ways of doing this, want serverside validation - never want validate on users end. how can limit value input using angularjs? adding listener on model in angularjs 1 (and 'think' want), can update 'something' according being input text area.

how object reference(link) object array(levelarray)? f.e., levelarray has created object "level1" under index 1, , need change variables in object. how it? public class leveleditorscreen implements screen { final drop game; private batch batch; private array<level> levelarray; private int levelcount; private void createlevel(int lvlcount) { levelcount += 1; lvlcount = levelcount; levelarray.add(new level()); } } if know index can use get(int index) method. levelarray.get(0); //this return object of index 0 if don't know index, know variable set specific value can desired object: in example level has variable string name for(level level : levelarray) { if(level.name.equals("awesome level")) { //we found desired level! } }

as title indicates have dyadic-year data. problem have (for reason...) duplicated dyadic column names – example, shown below, a , b b observations make no sense. real data on 70.000 observations. what want generate dummy variable indicate same-same dyadic observations. person1 person2 year 1990 1991 1992 b 1990 b 1991 b 1992 c 1990 c 1991 c 1992 b b 1990 b b 1991 b b 1992 ... the function duplicated() doesn't help, other basic r commands since it's dyadic data. here's reproducible example structure(list(person1 = structure(c(1l, 1l, 1l, 1l, 1l, 1l, 1l, 1l, 1l, 2l, 2l, 2l, 2l, 2l, 2l, 2l, 2l, 2l, 3l, 3l, 3l, 3l, 3l, 3l, 3l, 3l, 3l), .la
