• Getting time from a cell in Google Spreadsheet

  - by lostInTransit

  Hi I have created a Google Spreadsheet form in which for one of the fields I get the time (hh:mm:ss) in 24-hour format. I am using Google Apps Scripts to read values from this spreadsheet and put it into another file. But the other file gets the entire date (don't know from where) and shows a date from 1899. Also the time is shown in PDT (not my time zone). Even the time it prints is not correct How do I read the column value as a string and put it in the other file OR get just the time from the column value (and the correct time) I am using a simple row[0][3] to get the values from an array after doing range.getValues() Thanks.

• Ajax request. Which callback is executed first complete or success?

  - by Gutzofter

  I could spike this to find out, but I'm going to use SO. In my unit tests (qunit) I use the asynchShould (alias for asynchTest) test. Part of the assertion is to wait for the completion/success of the request. Like this: asyncShould('talk to customer list server', 1, function() { stop(2000); var forCustomerList = newCustomerListRequest(); forCustomerList.page = 'helpers/helper.php'; forCustomerList.data += '&action=customerListServer&DB=11001'; var originalSuccess = forCustomerList.success; forCustomerList.success = function(msg) { if (msg.flash !== undefined && msg.data !== undefined && msg.status !== undefined) { ok(true, 'json structure correct') } else { ok(false, 'json structure not correct'); } originalSuccess(msg); start(); }; testController.getServerData(forCustomerList); })

• Python lxml - returns null list

  - by Chris Finlayson

  I cannot figure out what is wrong with the XPATH when trying to extract a value from a webpage table. The method seems correct as I can extract the page title and other attributes, but I cannot extract the third value, it always returns an empty list? from lxml import html import requests test_url = 'SC312226' page = ('https://www.opencompany.co.uk/company/'+test_url) print 'Now searching URL: '+page data = requests.get(page) tree = html.fromstring(data.text) print tree.xpath('//title/text()') # Get page title print tree.xpath('//a/@href') # Get href attribute of all links print tree.xpath('//*[@id="financial"]/table/tbody/tr/td[1]/table/tbody/tr[2]/td[1]/div[2]/text()') Unless i'm missing something, it would appear the XPATH is correct: Chrome screenshot I checked Chrome console, appears ok! So i'm at a loss $x ('//*[@id="financial"]/table/tbody/tr/td[1]/table/tbody/tr[2]/td[1]/div[2]/text()') [ "£432,272" ]

• Putting li's into rows

  - by panthro

  I have a long list of li's. <ul> <li> <img src="test.jpg"> </li> <li> <img src="test.jpg"> </li> //etc Each li has this styling: width: 10%; display: inline-block; vertical-align: middle; When I get to more than 10 li's in a row, they go on to the next row. Is this the correct way to do it? or should I wrap each 10 li's into something that breaks the line? What the best/correct method? i intialy chose this method as it would be easily to loop out data from a database.

• Rails gives wrong headers after upgrade 2.3.5 -> 2.3.8

  - by macsniper

  I just upgraded from rails 2.3.5 to rails 2.3.8, but now my redirects are not working properly. I get the following as the response HTTP Headers: HTTP/1.1 302 Moved Temporarily Date: Wed, 02 Jun 2010 09:40:39 GMT Content-Length: 93 Content-Type: text/html whereas I got previous: HTTP/1.1 302 Moved Temporarily Connection: close Date: Wed, 02 Jun 2010 09:41:18 GMT Set-Cookie: _session_id=<correct id>; path=/ Status: 302 Found Location: <correct url> Cache-Control: no-cache Server: Mongrel 1.1.5 Content-Type: text/html; charset=utf-8 Content-Length: 93 Anyone knows how to fix this? Despite the fact that the redirect is not working, the login-cookie is not set too (but I think, this is both related somehow). I have already tried to override redirect_to in order to set response.headers['Location'] etc., but they did not appear in the response.

• unused memory using 32 bit integer in C

  - by endmade

  I have the folowing struct of integers (32 bit environment): struct rgb { int r; int g; int b; }; Am I correct in saying that, since rgb component values (0-255) only require 8-bits(1 byte) to be represented, I am only using 1 byte of memory and leaving 3 bytes unused for each component? Also, if I instead did the following: struct rgb{ unsigned int r:8; unsigned int g:8; unsigned int b:8; }; Assuming that what I said above is correct, would using this new struct reduce the number of unused bytes to 1?

• Performance of Serialized Objects in C++

  - by jm1234567890

  Hi Everyone, I'm wondering if there is a fast way to dump an STL set to disk and then read it back later. The internal structure of a set is a binary tree, so if I serialize it naively, when I read it back the program will have to go though the process of inserting each element again. I think this is slow even if it is read back in correct order, correct me if I am wrong. Is there a way to "dump" the memory containing the set into disk and then read it back later? That is, keep everything in binary format, thus avoiding the re-insertion. Do the boost serialization tools do this? Thanks! EDIT: oh I should probably read, http://www.parashift.com/c++-faq-lite/serialization.html I will read it now... no it doesn't really help

• specifying multiple Error in aov

  - by essopapas

  Greetings to all This is my model: aov.fit<-aov(Y~A+B+C+D+E+A:C+A:E, data=dat) In summary(aov.fit) all F values are comptuted by eg MS(A)/MS(Residuals). This is not correct (or what I want), except for F(B) and F(A:E). I suppose P values are not correct either. Can I specify how the F computations will be done? I 'd like them to be like this: F(A)=MS(A)/MS(E), F(C)=MS(C)/MS(E), F(D)=MS(D)/MS(E), F(E)=MS(E)/MS(A:E), F(A:C)=MS(A:C)/MS(A:E) thanks

• In PHP can I check a boolean on a function call?

  - by Chris

  I have a function which checks the passed value and returns false or true, if false I want it to add something to an array. The code I've written is below. if(!check_input($_POST['username'])){ $errors[] = "Username"; } Right now it adds to my array anyway, regardless of what is entered in the form. Is the way I've written that the correct way to check if the return from check_input() is false? I've checked the function's logic by altering the returns to echoes and it's returning the correct value, I'm just not sure if I'm checking it wrong. I'd previously attempted to write it as $X=check_input etc, and then if(check_value == false) but that doesn't seem to give me the desired result either. Hmmm a quick pointer please!

• Warning of "Control may reach end of non-void function"

  - by Cloud_cal

  I ran a C++ program in Xcode, and encountered a warning of "Control may reach end of non-void function". Here is the code: Node* search(Node* head, int x) { if(!head) return NULL; else if(x == head->key) return head; else if(x < head->key) search(head->lchild, x); else search(head->rchild, x); } I got the same warning when compiling it in Linux, but got the correct result. But in Xcode, the result was wrong. By the way, I got the correct answer and no warning in Visual Studio.

• Django template CSS/IMG is "off" in the URL

  I have /path/to/my/theme/static/css/frontend.css which is called by base.html <link rel="stylesheet" type="text/css" href="{{ STATIC_URL }}css/frontend.css" media="all" /> In which I've got a background for the header: #header-wrapper min-width: 960px; height: 150px; background: transparent url(img/header-bg.png) repeat-x center bottom; } The file is /path/to/my/theme/static/img I've run manage.py collectstatic to gather the files and almost everything looks correct except the link generated looks like: http://example.com/static/css/img/header-bg.png In which the image does not show, because the correct URL is: http://example.com/static/img/header-bg.png Where am I going wrong??

• Calling finish() After Starting a New Activity

  - by stormin986

  The first Activity that loads in my application is an initialization activity, and once complete it loads a new Activity. I want to ensure if the user presses 'Back' they go straight to the Launcher, and not the initialization screen. Side note, is this even the best approach, or would this be better done with some kind of Intent Flag? Is it correct to call finish() after calling startActivity() on the new activity? onCreate() { ... startActivity(new Intent(this, NextActivity.class)); finish(); ... } I'm still taking in the whole 'Message Queue' method of doing things in Android, and my assumption is that calling startActivity() and then finish() from my first Activity's onCreate() will log each respective message in the message queue, but finish execution of onCreate() before moving on to starting the next Activity and finishing my first one. Is this a correct understanding?

• best practice for Jquery plugin implementation and resource locations

  - by ptutt

  This is probably a very basic question, but I seem to have issues plugging in jquery plug-ins. The issue seems to be around the location of the script, css and images and ensuring the css has the correct url to the images. The standard plug-in has the following folder structure (eg : JPicker) js css images My project is asp.net mvc so I have the default: scripts images content So, I try to split the jquery plugin to the appropriate folders (not sure if this is the best way?). Then I try to correct the references to images (background urls) in the css. I believe the url is relative to the page that is implementing the css file, not the location of the css file itself. Anyway, when I try the above, the plugins don't seem to work. I believe the issue lies with the images not being found. The jquery code runs without errors, so I assume that's not the problem. Any help/advice much appreciated

• Godaddy registrar and Amazon Web Services EC2/Route 53

  - by soshannad

  Ok - I currently have a site hosted on Godaddy and they are the registrar for my domain. My goal is to have my site hosted on AWS with an EC2 server, which I have already set up and it is ready to go. In order to migrate my domain name to Amazon I have set up an A record with Godaddy and another A record with Route 53 (Amazon's routing service) with both of them pointing to the new static IP of the AWS site. My question is - Godaddy told me that I should leave my nameservers as Godaddy since my email is with them and set up an MX record wit Amazon pointing to it. Does this sound correct? Can you leave nameservers with Godaddy and have A records pointed to the new IP? Are there any benefits/cons to this? *FOR THE RECORD - My site is DOWN right now after doing the change - Godaddy says it will take 2 hours to come back, but I'm not sure if their nameserver recommendation is correct.

• Calculating a parabola: What am I doing wrong? [closed]

  - by Nils

  I was following this thread and copied the code in my project. Playing around with it turns out that it seems not to be very precise. Recall the formula: y = ax^2 + bx +c Since the first given point I have is at x1 = 0, we already have c=y1 . We just need to find a and b. Using: y2 = ax2^2 + bx2 +c y3 = ax3^2 + bx3 +c Solving the equations for b yields: b = y/x - ax - cx Now setting both equations equal to each other so b falls out y2/x2 - ax2 - cx2 = y3/x3 - ax3 - cx3 Now solving for a gives me: a = ( x3*(y2 - c) + x2*(y3 - c) ) / ( x2*x3*(x2 - x3) ) (is that correct?!) And then using again b = y2/x2 - ax2 - cx2 to find b. However so far I haven't found the correct a and b coeffs. What am I doing wrong?

• Number guessing game (3+- guessed result)

  - by Nick Waring

  I've been assigned a task to create a game that generates 4 digits and the user has to guess the digits one at a time to get the correct result. If the number is correct a Y is displayed and if not, a N. This was easy, now the next step was to implement another two responses. If the answer is too high, a H is displayed and too low, an N. Again, was easy - now the third is to use the same design as game 2 but if the number is 3 higher than a H is displayed and same if it's 3 lower than a L is displayed - otherwise an X is displayed. I can't figure out how to do this. Here's my test code for game 2 for just one of the digits - any help is appreciated. (5 was used just for a test.) def guess(): x = 5 g= int(input("Guess the number: ")) if g == x: print("Y") elif g < x: print("L") else: print("H")

• MEF Why is ComposePart an extension method?

  - by ILovePaperTowels

  CompositionContainer.ComposePart is an extension method. why is that? Looking into the System.Componentmodel.Composition assembly, it looks like it's because it is ONLY meant to work with the attributed programming model while the .Compose() method is able to take in exports as long as it is a composablepart. ComposePart is even hosted in the 'AttributedModelServices' class which makes me think I'm correct. Am I correct on this? If not, why is it an extension method and not a method in the container class?

• Rails: saving a string on an object -- syntax problem?

  - by Veep

  Hey there, I am trying to write a simple function to clean a filename string and update the object. When I save a test string it works, but when I try to save the string variable I've created, nothing happens. But when I return the string, the output seems to be correct! What am I missing? def clean_filename clean_name = filename clean_name.gsub! /^.*(\\|\/)/, '' clean_name.gsub! /[^A-Za-z0-9\.\-]/, '_' clean_name.gsub!(/\_+/, ' ') #update_attribute(:filename, "test") #<-- correctly sets filename to test #update_attribute(:filename, clean_name) #<-- no effect????? WTF #return clean_name <-- seems to returns the correct string end Thank you very much.

• Buttons created through jquery don't respond to clicks

  - by Atrus

  As I've come to understand using $('.whatever').click() only works for items created initially. Additional items won't respond in the correct fashion. I was then directed to using something like $('.whatever).on('click', myFunction()). However, I'm not detecting any difference, as newly created items are not called. Here is a JSFiddle demonstration my example code: http://jsfiddle.net/atrus6/zaKZN/ My initial input plus 'Kill' will work in the correct fashion, however any additional 'input + kill's will not not do anything. Am I incorrectly using .on() or is it something else?
