• Hbase / Hadoop Query Help

  - by zechariahs

  I'm working on a project with a friend that will utilize Hbase to store it's data. Are there any good query examples? I seem to be writing a ton of Java code to iterate through lists of RowResult's when, in SQL land, I could write a simple query. Am I missing something? Or is Hbase missing something?

• Uploading file from file object with PyCurl

  - by Tom

  I'm attempting to upload a file like this: import pycurl c = pycurl.Curl() values = [ ("name", "tom"), ("image", (pycurl.FORM_FILE, "tom.png")) ] c.setopt(c.URL, "http://upload.com/submit") c.setopt(c.HTTPPOST, values) c.perform() c.close() This works fine. However, this only works if the file is local. If I was to fetch the image such that: import urllib2 resp = urllib2.urlopen("http://upload.com/people/tom.png") How would I pass resp.fp as a file object instead of writing it to a file and passing the filename? Is this possible?

• DropDownList doesn't postback on SelectedIndexChanged

  - by Sergey Volegov

  I'm writing an ASP.Net webform with some DropDownList controls on it. Then user changes selected item in one of dropdowns, ASP.Net doesn't seem to handle SelectedIndexChanged event until form is submitted with a 'Submit' button click. How do I make my dropdowns handle SelectedIndexChanged instantly? P.S. It's a classic question I have answered too many times, but it seems no one asked it before on stackoverflow.

• Drag and Drop file upload in Silverlight 4?

  - by Parvenu74

  I'm working on re-writing a WinForms application into Silverlight. One use case in the WinForms app allows users to drag TIFF images (of faxes) from Outlook directly onto an "attach an image or fax to this case" control in the WinForms app. Is there a Silverlight 4 control which allows for the same functionality? It's important to realize that saving the file to the local filesystem and then selecting and uploading the file with a standard upload control will not meet the business requirements as outlined in the project.

• Does changing window.location stop execution of javascript?

  - by Aleksander Kmetec

  When writing server-side code you need to explicitly stop execution after sending a "Location: ..." header to the client or your code will continue to execute in the background. But what about when you change window.location in a client-side script? Does this immediately stop execution of the current script or is it up to the programmer to make sure that any code located after this call is not reached?

To write out normal parameters in JDT you could do something like the following Signature.createTypeSignature("int", false)

• Method name collision in interface implementation - Java

  - by Bhaskar

  If I have two interfaces , both quite different in their purposes , but with same method signature , how do I make a class implement both without being forced to write a single method that serves for the both the interfaces and writing some convoluted logic in the method implementation that checks for which type of object the call is being made and invoke proper code ? In C# , this is overcome by what is called as explicit interface implementation. Is there any equivalent way in Java ?

• Wanted: a very simple java RegExp API

  - by itsadok

  I'm tired of writing Pattern p = Pattern.compile(... Matcher m = p.matcher(str); if (m.find()) { ... Over and over again in my code. I was going to write a helper class to make it neater, but I then I wondered: is there a library that tries to provide a simpler facade for Regular Expressions in Java? I'm thinking something in the style of commons-lang and Guava.

• Hyphens or underscores in CSS and HTML identifiers?

  - by Török Gábor

  As both hyphen (-) and underscore (_) are valid characters in CSS and HTML identifiers, what are the advantages and disadvantages using one or the other? I prefer writing CSS class names with hyphens (e.g. field-text) and underscores for IDs (e.g. featured_content). Is there a best practice or it's only the matter of taste?

• RTS AI: where to start?

  - by awegawef

  I'd like to begin tinkering around with an RTS AI, but I'm having trouble finding a good environment to work with, ie a game that has been already created. I have looked at Spring RTS and Bos Wars, but they don't seem to be conducive to creating simple examples. I am not totally opposed to writing my own game environment, it would just take a long time. Does anyone have a suggestion as to how I can get my feet wet without programming my own game?

• lexer/parser ambiguity

  - by John Leidegren

  How does a lexer solve this ambiguity? /*/*/ How is it that it doesn't just say, oh yeah, that's the begining of a multi-line comment, followed by another multi-line comment. Wouldn't a greedy lexer just return the following tokens? /* /* / I'm in the midst of writing a shift-reduce parser for CSS and yet this simple comment thing is in my way.
