• C++: type Length from float

  - by anon

  This is kinda like my earlier question: http://stackoverflow.com/questions/2451175/c-vector3-type-wall Except, now, I want to do this to a builtin rather then a user created type. So I want a type "Length" that behaves just like float -- except I'm going to make it's constructor explicit, so I have to explicitly construct Length objects (rather than have random conversions flying around). Basically, I'm going into the type-a-lot camp.

• Is is faster to filter and get data or filter then get data ?

  - by remi bourgarel

  Hi I have this kind of request : SELECT myTable.ID, myTable.Adress, -- 20 more columns of all kind of type FROM myTable WHERE EXISTS(SELECT * FROM myLink WHERE myLink.FID = myTable.ID and myLink.FID2 = 666) myLink has a lot of rows. Do you think it's faster to do like this : SELECT myLink.FID INTO @result FROM myLink WHERE myLink.FID2 = 666 UPDATE @result SET Adress = myTable.Adress, -- 20 more columns of all kind of type FROM myTable WHERE myTable.ID = @result.ID

• What does the exception "javax.servlet.jsp.JspException: Broken pipe" signify?

  - by Ruepen

  I'm getting the following error: javax.servlet.jsp.JspException: Broken pipe Now I have seen questions/answers with respects to the socket exception, but this error is coming from a different package. Any help is greatly appreciated. BTW, I am seeing quite a lot of these errors in a struts web app Weblogic Node logs and I am thinking that it has to do with end users closing their web browser before the page reloads/executes the next step (database transaction which takes quite a bit of time to execute, anywhere from 30 seconds to 4 mins).

• Correct term for PSD to HTML to CMS

  - by John Magnolia

  Hi, I have heard a lot of different terms to describe the process of turning a website design into a editable CMS. Currently I take the design and "slice" this up into HTML and CSS then I "plug" this into a CMS. I would class this as frontend development depending on the level of customisation required for the CMS. The reason I ask is I am currently writing up my CV and have become stuck on the correct term for this. Kind Regards

• How to reload python module from itself?

  - by mivulf

  I have a python module with a lot of variables. These variables are used and changed by many other modules. And I want to reload this module from itself when it happens (for refresh). How to do that? # ================================== # foo.py spam = 100 def set_spam(value): spam = value foo = reload(foo) # reload module from itself # ================================== # bar.py import foo print foo.spam # I expect 100 # assume that value changes here from some another modules (for example, from eggs.py, apple.py and fruit.py) foo.set_spam(200) print foo.spam # I expect 200

• Is a string formatter that pulls variables from its calling scope bad practice?

  - by Eric

  I have some code that does an awful lot of string formatting, Often, I end up with code along the lines of: "...".format(x=x, y=y, z=z, foo=foo, ...) Where I'm trying to interpolate a large number of variables into a large string. Is there a good reason not to write a function like this that uses the inspect module to find variables to interpolate? import inspect def interpolate(s): return s.format(**inspect.currentframe().f_back.f_locals) def generateTheString(x): y = foo(x) z = x + y # more calculations go here return interpolate("{x}, {y}, {z}")

• Counting context switches per thread

  - by Sarmun

  Is there a way to see how many context switches each thread generates? (both in and out if possible) Either in X/s, or to let it run and give aggregated data after some time. (either on linux or on windows) I have found only tools that give aggregated context-switching number for whole os or per process. My program makes many context switches (50k/s), probably a lot not necessary, but I am not sure where to start optimizing, where do most of those happen.
