• Why is my substitution control suddenly not working in ASP.NET 4.0?

  - by Steve Wortham

  I just upgraded my site from ASP.NET 3.5 to 4.0. I've been working through some breaking changes (there were more than I expected). One I can't figure out, however, is why my <asp:Substitution /> control suddenly stopped working like it should. It's supposed to ignore the output cache settings of the parent page and update upon every request. For some reason that isn't happening. It's caching for the full 10 minutes (the OutputCache setting for my home page). Any ideas?

• create a sparse BufferedImage in java

  - by elgcom

  I have to create an image with very large resolution, but the image is relatively "sparse", only some areas in the image need to draw. For example with following code /* this take 5GB memory */ final BufferedImage img = new BufferedImage( 36000, 36000, BufferedImage.TYPE_INT_ARGB); /* draw something */ Graphics g = img.getGraphics(); g.drawImage(....); /* output as PNG */ final File out = new File("out.png"); ImageIO.write(img, "png", out); The PNG image on the end I created is ONLY about 200~300 MB. The question is how can I avoid creating a 5GB BufferedImage at the beginning? I do need an image with large dimension, but with very sparse color information. Is there any Stream for BufferedImage so that it will not take so much memory?

• nicely display file rename history in git log

  - by Jian

  The git command git log --format='%H' --follow -- foo.txt will give you the series of commits that touch foo.txt, following it across renames. I'm wondering if there's a git log command that will also print the corresponding historical file name beside each commit. It would be something like this, where we can interpret '%F' to be the (actually non-existent) placeholder for filename. git log --format='%H %F' --follow -- foo.txt I know this could be accomplished with git log --format='%H' --follow --numstat -- foo.txt but the output is not ideal since it requires some non-trivial parsing; each commit is strewn across multiple lines, and you'll still need to parse the file rename syntax ("bar.txt => foo.txt") to find what you're looking for.

• How can I convert a file full of unix time strings to human readable dates?

  - by skymook

  I am processing a file full of unix time strings. I want to convert them all to human readable. The file looks like so: 1153335401 1153448586 1153476729 1153494310 1153603662 1153640211 Here is the script: #! /bin/bash FILE="test.txt" cat $FILE | while read line; do perl -e 'print scalar(gmtime($line)), "\n"' done This is not working. The output I get is Thu Jan 1 00:00:00 1970 for every line. I think the line breaks are being picked up and that is why it is not working. Any ideas? I'm using Mac OSX is that makes any difference.

• Nokogiri Not Parsing File

  - by Jesse J

  I'm using Nokogiri to parse pepXML files from different peptide search engines. I have two pepXML files, both of which appear, inasmuch as I can tell, to be of correct format, and puts Nokogiri::XML(IO.read(file)) will output the whole XML file for both files. The problem is, doc.xpath("any valid xpath") will parse the tag from one of the files, but not the other. No errors are given, so I have no idea why it won't parse. Anyone know of any reasons why Nokogiri wouldn't parse something out?

• Sqlite3 activerecord :order => "time DESC" doesn't sort

  - by Ole Morten Amundsen

  rails 2.3.4, sqlite3 I'm trying this Production.find(:all, :conditions = ["time ?", start_time.utc], :order = "time DESC", :limit = 100) The condition works perfectly, but I'm having problems with the :order = time DESC. By chance, I discovered that it worked at Heroku (testing with heroku console), which runs PostgreSQL. However, locally, using sqlite3, new entries will be sorted after old ones, no matter what I set time to. Like this (output has been manually stripped): second entry is new: Production id: 2053939460, time: "2010-04-24 23:00:04", created_at: "2010-04-24 23:00:05" Production id: 2053939532, time: "2010-04-25 10:00:00", created_at: "2010-04-27 05:58:30" Production id: 2053939461, time: "2010-04-25 00:00:04", created_at: "2010-04-25 00:00:04" Production id: 2053939463, time: "2010-04-25 01:00:04", created_at: "2010-04-25 01:00:04" Seems like it sorts on the primary key, id, not time. Note that the query works fine on heroku, returning a correctly ordered list! I like sqlite, it's so KISS, I hope you can help me... Any suggestions?

• Strange behavior of Switch Case statement in Java

  - by supernova

  I understand that Java switch case are designed this way but why is this behavior in Java int x = 1; switch(x){ case 1: System.out.println(1); case 2: System.out.println(2); case 3: System.out.println(3); default: System.out.println("default"); } output : 1 2 3 default My question is why case 2 and 3 are executed? I know I omitted break statement but x was never 2 or 3 but case 2 and case 3 still executes?

• How can I detect if a file is binary (non-text) in python?

  - by grieve

  How can I tell if a file is binary (non-text) in python? I am searching through a large set of files in python, and keep getting matches in binary files. This makes the output look incredibly messy. I know I could use grep -I, but I am doing more with the data than what grep allows for. In the past I would have just searched for characters greater than 0x7f, but utf8 and the like make that impossible on modern systems. Ideally the solution would be fast, but any solution will do.

  "My search returns a highlighted fragment from a field. I want to know that in that field of particular searched document, where does that fragment starts and ends ?" for instance. consider i am searching "highlighted fragment" in above lines (consider the above para as single document). I am setting my fragmenter as : SimpleFragmenter fragmenter = new SimpleFragmenter(30); now the output of GetBestFragment is somewhat like : "returns a highlighted fragment from" Is it possible to get the starting and ending index of this fragment in the text above (say starting is 10 and ending is 45)

• My Ruby Code: How can I improve? (Java to Ruby guy)

  - by steve

  Greetings, I get the feeling that I'm using ruby in an ugly way and possibly missing out on tonnes of useful features. I was wondering if anyone could point out a cleaner better way to write my code which is pasted here. The code itself simply scrapes some data from yelp and processes it into a json format. The reason I'm not using hash.to_json is because it throws some sort of stack error which I can only assume is due to the hash being too large (It's not particularly large). Response object = a hash text = the output which saves to file Anyways guidance appreciated. def mineLocation client = Yelp::Client.new request = Yelp::Review::Request::GeoPoint.new(:latitude=>13.3125,:longitude => -6.2468,:yws_id => 'nicetry') response = client.search(request) response['businesses'].length.times do |businessEntry| text ="" response['businesses'][businessEntry].each { |key, value| if value.class == Array value.length.times { |arrayEntry| text+= "\"#{key}\":[" value[arrayEntry].each { |arrayKey,arrayValue| text+= "{\"#{arrayKey}\":\"#{arrayValue}\"}," } text+="]" } else text+="\"#{arrayKey}\":\"#{arrayValue}\"," end } end end

• Documenting preprocessor defines in Doxygen

  - by Fire Lancer

  Is it possible to document preprocessor defines in Doxygen? I expected to be able to do it just like a variable or function, however the Doxygen output appears to have "lost" the documentation for the define, and does not contain the define its self either. I tried the following /**My Preprocessor Macro.*/ #define TEST_DEFINE(x) (x*x) and /**@def TEST_DEFINE My Preprocessor Macro. */ #define TEST_DEFINE(x) (x*x) I also tried putting them within a group (tried defgroup, addtogroup and ingroup) rather than just at the "file scope" however that had no effect either (although other items in the group were documented as intended). I looked through the various Doxygen options, but couldn't see anything that would enable (or prevent) the documentation of defines.

• NSDateFormatter iOS6 issue

  - by Angad Manchanda

  I have written a code for UIButton press to decrement date. The present date is shown in a UILabel text property and it changes to the previous date when the button is pressed. The following code works perfectly fine for iOS5 but doesn't work with iOS6. With iOS6, it gives the output as Dec 31, 1999 or null. - (IBAction)showPrevDate:(id)sender { NSString *dateForDecrement = _showDateLbl.text; [dateFormatter setDateFormat:@"MMM d, yyyy (EEE)"]; NSDate *dateObjectForDecrement = [dateFormatter dateFromString:dateForDecrement]; int subtractDays = 1; dateAfterDecrement=[dateObjectForDecrement dateByAddingTimeInterval:-(24*60*60 * subtractDays)]; _showDateLbl.text = [NSString stringWithFormat:@"%@", [dateFormatter stringFromDate:dateAfterDecrement]]; } Can anybody verify this, or tell me if its's a bug in iOS6 ? Thanks guys.

• Python - calendar.timegm() vs. time.mktime()

  - by ibz

  I seem to have a hard time getting my head around this. What's the difference between calendar.timegm() and time.mktime()? Say I have a datetime.datetime with no tzinfo attached, shouldn't the two give the same output? Don't they both give the number of seconds between epoch and the date passed as a parameter? And since the date passed has no tzinfo, isn't that number of seconds the same? >>> import calendar >>> import time >>> import datetime >>> d = datetime.datetime(2010, 10, 10) >>> calendar.timegm(d.timetuple()) 1286668800 >>> time.mktime(d.timetuple()) 1286640000.0 >>>

• remote function with pthread

  Hi all, I wrote some code in c, using pthread (I configured the linker and compiler in eclipse IDE first). #include <pthread.h> #include "starter.h" #include "UI.h" Page* MM; Page* Disk; PCB* all_pcb_array; void* display_prompt(void *id){ printf("Hello111\n"); return NULL; } int main(int argc, char** argv) { printf("Hello\n"); pthread_t *thread = (pthread_t*) malloc (sizeof(pthread_t)); pthread_create(thread, NULL, display_prompt, NULL); printf("Hello\n"); return 1; } that works fine. However, when I move display_prompt to UI.h no "Hello111 " output is printed. anyone know how to solve that? Elad

• XML Parsing in Groovy strips attribute new lines

  - by Bill James

  I'm writing code where I retrieve XML from a web api, then parse that XML using Groovy. Unfortunately, it seems that both XmlParser and XmlSlurper for Groovy strip newline characters from the attributes of nodes when .text() is called. How can I get at the text of the attribute including the newlines? Sample code: def xmltest = ''' <snippet> <preSnippet att1="testatt1" code="This is line 1 This is line 2 This is line 3" > <lines count="10" /> </preSnippet> </snippet>''' def parsed = new XmlParser().parseText( xmltest ) println "Parsed" parsed.preSnippet.each { pre -> println pre.attribute('code'); } def slurped = new XmlSlurper().parseText( xmltest ) println "Slurped" slurped.children().each { preSnip -> println [email protected]() } the output of which is: Parsed This is line 1 This is line 2 This is line 3 Slurped This is line 1 This is line 2 This is line 3

• Issuing native system commands in Scala

  - by Tony

  I want to issue a native system command from a Scala program, and perhaps trap the output. ("ls" comes to mind. There may be other ways to get directory information without issuing the command, but that's beside the point of my question.) It would correspond to os.system(...) in Python. I've looked in "Programming in Scala". I've looked in O'Reilly's "Programming Scala". I've Googled several combinations of terms. No luck yet. Can someone out there give me an example, or point me at a resource where I can find an example?

• ColdFusion static key/value list?

  - by richardtallent

  I have a database table that is a dictionary of defined terms -- key, value. I want to load the dictionary in the application scope from the database, and keep it there for performance (it doesn't change). I gather this is probably some sort of "struct," but I'm extremely new to ColdFusion (helping out another team). Then, I'd like to do some simple string replacement on some strings being output to the browser, looping through the defined terms and replacing the terms with some HTML to define the terms (a hover or a link, details to be worked out later, not important). Can anyone point me in the right direction of: How to define the stucture (if that is what I need for a key/value pair list) How to query at the application start-up and reuse the list properly The best way to do the string replacement

• How are variables bound to the body of a define_method?

  - by Chris

  While trying to brush up my Ruby skills I keep running across this case which I can't figure out an explanation for by just reading the API docs. An explanation would be greatly appreciated. Here's the example code: for name in [ :new, :create, :destroy ] define_method("test_#{name}") do puts name end end What I want/expect to happen is that the name variable will be bound to the block given to define_method and that when #test_new is called it will output "new". Instead each defined method outputs "destroy" -- the last value assigned to the name variable. What am I misunderstanding about define_method and its blocks? Thanks!

• Passing URIs as URL arguments in Drupal

  - by wynz

  I'm running into problems trying to pass absolute URIs as parameters with clean URLs enabled. I've got hook_menu() set up like this: function mymodule_menu() { return array( 'page/%' = array( 'title' = 'DBpedia Display Test', 'page callback' = 'mymodule_dbpedia_display', 'page arguments' = array(1), ), ); } and in the page callback: function mymodule_dbpedia_display($uri) { // Make an HTTP request for this URI // and then render some things return $output; } What I'm hoping to do is somehow pass full URIs (e.g. "http://dbpedia.org/resource/Coffee") to my page callback. I've tried a few things and nothing's worked so far... http://mysite.com/page/http%3A%2F%2Fdbpedia.org%2Fresource%2FCoffee Completely breaks Drupal's rewriting http://mysite.com/page/?uri=http%3A%2F%2Fdbpedia.org%2Fresource%2FCoffee Gives a 404 http://mysite.com/page/http://dbpedia.org/resource/Coffee Returns just "http:", which makes sense I could probably use $_GET to pull out the whole query string, but I guess I'm hoping for a more 'Drupal' solution. Any suggestions?
