• “Function” calling inside store procedure

  - by idimba

  Hi, I have a big store procedure, that contains a lot of INSERTs. There're many INSERTS that almost identical - they're different by some parameter(s) (all INSERTs to the same table) Is there a way to create a function/method, to which I'll pass the above parameter(s) and the function/method will generate concrete INSERT's? Thanks

• Collision free hash function for a specific data structure

  - by Max

  Is it possible to create collision free hash function for a data structure with specific properties. The datastructure is int[][][] It contains no duplicates The range of integers that are contained in it is defined. Let's say it's 0..1000, the maximal integer is definitely not greater than 10000. Big problem is that this hash function should also be very fast. Is there a way to create such a hash function? Maybe at run time depending on the integer range?

• How can I visually format JSON data (programmatically)?

  - by Ian Robinson

  I'm working with big blobs of JSON. These blobs change slightly over time and a revision history is kept. I'd really like to be able to do a visual diff on them, but my problem is they're being stored without any formatting at all - everything is on one line, so that makes it a little hard to see what changed. Is there a good way to programatically format them ala http://jsonformat.com/ or http://jsonformatter.curiousconcept.com/?

• What browser incompatibilities does jquery solve?

  - by pd1138

  I'm currently on the fence about using or not using jquery. I've spent hours researching the pros and cons of using jquery (or any library for that matter). One of the big selling points of jquery is that it frees a developer from worrying about browser incompatibilities. I've tried to find any documentation on exactly which incompatibilities it overcomes. So far I haven't found any. Can anyone help me out with this.

• What's the best way to use python-syntax config files (in python of course)?

  - by Gabe

  My config file is really just a big python dict, but I have many config files to run different experiments and I want to 'import' a different one based on a command line option. Instinctively I want to do import ConfigFileName where ConfigFileName is a string with the config file's python package name in it... but that doesn't work. Any ideas?

  - by brilliant

  I know this question may well be the silliest question you've herd today, but to me it is a big question at this stage of my programming learning. Why is the second empty line needed in this Python code? What does that line do? print 'Content-Type: text/plain' print '' print 'Hello, world!'

• efficiently convert string (or tuple) to ctypes array

  - by Mu Mind

  I've got code that takes a PIL image and converts it to a ctypes array to pass out to a C function: w_px, h_px = img.size pixels = struct.unpack('%dI'%(w_px*h_px), img.convert('RGBA').tostring()) pixels_array = (ctypes.c_int * len(pixels))(*pixels) But I'm dealing with big images, and unpacking that many items into function arguments seems to be noticeably slow. What's the simplest thing I can do to get a reasonable speedup? I'm only converting to a tuple as an intermediate step, so if it's unnecessary, all the better.

• Using sed and/or awk, how can do a sed swap on all text in a file until I see a line matching a reg

  - by Ross Rogers

  How can I do a sed regex swap on all text that preceed a line matching a regex. e.g. How can I do a swap like this s/foo/bar/g for all text that precedes the first point this regex matches: m/baz/ I don't want to use positive/negative look ahead/behind in my sed regex, because those are really expensive operations on big files.

• Speeding up Math calculations in Java

  - by Simon

  I have a neural network written in Java which uses a sigmoid transfer function defined as follows: private static double sigmoid(double x) { return 1 / (1 + Math.exp(-x)); } and this is called many times during training and computation using the network. Is there any way of speeding this up? It's not that it's slow, it's just that it is used a lot, so a small optimisation here would be a big overall gain.

• Is passing a struct value to a method by-reference in C# an acceptable optimization?

  - by Arc

  Say I have a struct: struct MyStruct { public int X public int Y } And a method in some class that is iterated over many times elsewhere: public bool MyMethod( MyStruct myStruct ) { return ... } Is changing the MyMethod signature to the following an acceptable optimization? public bool MyMethod( ref MyStruct myStruct ) If so, how much of an advantage would it really be? If not, about how many fields would a struct need for a big enough advantage using ref this way?

• Should I move this task to a message queue?

  - by Fedyashev Nikita

  I'm a big fan of using message queue systems(like Apache ActiveMQ) for the tasks which are rather slow and do not require instant feedback in User Interface. The question is: Should I use it for other tasks(which are pretty fast) and do not require instant feedback in User Interface? Or does it in involve another level of complexity without not so much benefits?

Notice how the newArray only has home_ids from the big jsonArray array.

• What are the downside of not having an index.html file to some directories

  - by Pennf0lio

  Hi, I'm curious what are some effects/downside of not putting an index.html file to your directories (e.g images). I know when an index file is not present to a directory, files inside that directory are no longer private and will be visible to the browsers when point (eg yoursite.com/images/). Aside from that what are some big effects to consider? and how to properly secure them. thanks!

• What is the best way to modify a few fields in an XML using Java

  - by Kailas J C

  I have a big XML which contains around 300 elements. I need to modify 2 or 3 elements in this xml using Java. I don't want to go for conventional marshalling and unmarshalling as it involves the parsing of the whole XML. How is XPath/XSLT manipulation? I know that I can easily read the data but i need to modify the same and put in back in the same XML. The primary concern here is performance. Kindly advise
