i learning js, html, css, , general web development first time , wanted create simple (or thought) table use keeping track of items have. essentially want make dynamically-sized table can take , save input. i thinking of way make javascript function in order add tags tables input given. have seen personal website developer had input boxes submit button, causes data added in table in html file's table. for instance, if have: <table id="inventory"> <thead> <tr> <th>item name</th> <th>item number</th> <th>item color</th> </tr> </thead> </table> would possible me add <tr class = "boxtype"> <th>boxv1</th> <th>#1111</th> <th>blue</th> </tr> the above block table using javascript , inputs? i tried making addrows method after snooping around web, , created temporary version of table empty when re...

we know each file in hdfs occupy 300 bytes memory in namenode, because each file has 2 other replicates, 1 file totally occupy 900 bytes memory in namenode, or replicates don't occupy memory in namenode. looking @ optimisation name node memory usage , performance done @ hadoop-1687 can see memory usage blocks multiplied replication factor. however, memory usage files , directories not have increased cost based on replication. the number of bytes used block prior change (i.e. in hadoop 0.13) 152 + 72 * replication, giving figure of 368 bytes per block default replication setting of 3. files typically using 250 bytes, , directories 290 bytes, both regardless of replication setting. the improvements included 0.15 (which did include per-replication saving, there still per-replication cost). i haven't seen other references indicating per-replication memory usage has been removed.

following scikit-learn documentation labelshufflesplit , wish randomise train/validation batches ensure i'm training on possible data (e.g. ensemble). according doc, should see (indeed, notice train/validation sets are evenly split via test_size=0.5 ): >>> sklearn.cross_validation import labelshufflesplit >>> labels = [1, 1, 2, 2, 3, 3, 4, 4] >>> slo = labelshufflesplit(labels, n_iter=4, test_size=0.5, random_state=0) >>> train, test in slo: >>> print("%s %s" % (train, test)) ...

i have trigger execute when table updated. trigger updates table. i'd display changes of second table. this code have: create or replace trigger update_club_fee after update of fee on sporting_clubs each row begin update club_membership set amount = (duration*:new.fee) :old.club_id = :new.club_id; dbms_output.put_line('customer id is: '||:new.customer_id); dbms_output.put_line('previous amount '||:old.amount); dbms_output.put_line('new amount '||:new.amount); end; i don't think trigger appropriate tech solution. ui code captures change club membership should propagate changes child tables , deliver reporting. but if need use triggers, it's not going possible quite that: you cannot reference :old , :new on club_membership - these records relate trigger's owning table (sporting_clubs in case). :old.amount not resolve an update on 1 row in sporting_clubs may result in many rows being updated in club_membership (each clu...

this question has answer here: replace “\\” “\” in string in c# 7 answers in c# application, desktop folder doing : string path = environment.getfolderpath(environment.specialfolder.desktopdirectory); which gives string : "c:\\users\\username\\desktop". see there 2 slashes, problematic. there easy way delete slash each time meet them ? thank in advance. just know, "\\" 1 character - backslash escape character (it used in things \r or \n). since escape character, string representation of actual backslash, have escape it, leading double backslash, "\\". tldr: "\\" in string represents single backslash. if want verify this, try printing out string "\\". in general, remove duplicate character, can use .replace function: mystring.replace("xx", "x");

foreach (objecta in alist()) { foreach (objectb b in blist) { if (a.variable != b.variable1 && a.variable() != b.variable2) { a.setvariable("error"); } } } the problem getting goes through foreach loop first time , sets variable error without checking if other values (when goes through loop again) finds match. what wait until goes through lists , @ last foreach loop iteration if nothing in alist matches variable target && variable source in blist set error flag. any suggestions around appreciated. try doing other way around. search match instead of searching non-matches. foreach (objecta in alist()) { bool foundmatch = false; foreach (objectb b in blist) { if (a.variable == b.variable1 || a.variable() == b.variable2) { foundmatch = true; break; } } if (!foundmatch) { a.setvariable("error"); } } ...

how know uiview resizing , frame increasing or decreasing (or inner side or outer side)? for e.g. have uiimageview (and using third party library resize object). current frame is, (somex, somey, 200,50), if resize in way changes width 300 , in case changes 150. should able know that, increased/decreased. you can key-value observing . example, if uiimageview *imageview can: [imageview addobserver:self forkeypath:@"frame" options:0 context:null]; you need implement method in order react changes: - (void)observevalueforkeypath:(nsstring *)keypath ofobject:(id)object change:(nsdictionary *)change context:(void *)context { uiimageview *imageview = (uiimageview *)object; // gotta do, save current size in // instance variable can compare , see increase/decrease in size }

okay trying accomplish using while loops , using them efficiently. nested while loops tricky me , hard understand. trying make 10x10 multiplication table header. so current code is: firstnumber = int(input("please enter first number: ")) secondnumber = int(input("please enter second number: ")) count = 0 while(count < 1): print("{:17} {:5} {:5} {:5} {:5} {:5} {:5} {:5} {:5} {:5}"\ .format(firstnumber, firstnumber + 1, firstnumber + 2, firstnumber + 3,\ firstnumber + 4, firstnumber + 5, firstnumber + 6, firstnumber\ + 7, firstnumber + 8, firstnumber + 9)) print("{:5} {:}".format(" ", "-"*65)) count += 1 counter = 0 while(counter < 10): downsolution = firstnumber * secondnumber print("{:5} {:5} {:5} {:5} {:5} {:5} {:5} {:5} {:5} {:5} {:5} {:5}"\ .format(secondnumber, "|", downsolution,\ downsolu...

i'm looping through object. if 1 of keys matches value of fields object return value of type of fields object: // objects user: { email: '', password: '' } formfields: [ { name: 'email', type: 'text', required: true }, { name: 'password', type: 'password', required: true } ] // html <input :type="getproptype($key)" // function getproptype (key) { console.log(this.fields) console.log(key) return this.fields.map(field => { if (field.name === key) return field.type }) } it works except comma returned every field.type : which strange since logs don't output commas: what cause? i think trying extract type of object same name value of key, in case more appropriate solution - ie find element given name extract type getproptype(key) { console.log(this.fields) console.log(key); var type; this.fields.some(field => { if (field.name === key) { type =...

i'm using avcapturedevice capture video frame image process , control exposure duration, iso using setexposuremodecustomwithduration:(cmtime)duration iso:(float)iso completionhandler:(void (^)(cmtime synctime))handler and think keep exposure level setting. when set mode avcaptureexposuremodecustom, can see preview image's brightness changed when move camera capture different position. (especially light dark side) but when change exposure mode avcaptureexposuremodelocked, brightness fixed. i have been check white-balance, focus, torchmode locked or disable, isadjustingexposure keeping false, , exposure duration , iso parameter not change during problem happening. - (void) setcameraexposure:(cmtime)exposureduration iso:(int)iso { [self.avsession beginconfiguration]; avcapturedevice *videodevice = [avcapturedevice defaultdevicewithmediatype:avmediatypevideo]; if (videodevice) { [videodevice lockforconfiguration:nil]; // set exposure ...
