• Are any of these SQL Queries open to SQL injection attacks?

  - by Phil

  I have re-written my code after great help from some friendly stack overflow members (big thanks to Martin B and Kev Chadders especially). I would now like to check if my code is still open to SQL Injections after this work. I believe the code is now working as it should, but any blinding errors that you see i'd love to hear about too. My code is now looking like: -code removed-

• BigInteger.pow(BigInteger) ?

  - by PeterW

  I'm playing with numbers in Java, and want to see how big a number I can make. It is my understanding that BigInteger can hold a number of infinite size, so long as my computer has enough Memory to hold such a number, correct? My problem is that BigInteger.pow accepts only an int, not another BigInteger, which means I can only use a number up to 2,147,483,647 as the exponent. Is it possible to use the BigInteger class as such? BigInteger.pow(BigInteger) Thanks.

• CakePHP: Can I ignore a field when reading the Model from the DB?

  - by Daniel Magliola

  In one of my models, I have a "LONGTEXT" field that has a big dump of a bunch of stuff that I never care to read, and it slows things down, since I'm moving much more data between the DB and the web app. Is there a way to specify in the model that I want CakePHP to simply ignore that field, and never read it or do anything with it? I really want to avoid the hassle of creating a separate table and a separate model, only for this field. Thanks! Daniel

• Visual Studio incorrectly smart indents the opening brace

  - by PretzelSteelersFan

  When I type the closing brace in an html page, this i what Visual Studio does. Notice the opening brace is now 1 indent before the foreach. They should be even as shown by the closing brace. Not a big thing but driving me nuts. <% foreach (var item in Model.Messages) { %> <% } %>

• EADDRNOTAVAIL when binding 127.0.0.1 on localhost?

  - by Jonas Byström

  I'm getting errno==49 (EADDRNOTAVAIL) when trying to UDP-bind() to 127.0.0.1:47346 running Mac OS X on a G5 (big endian PowerPC). Is there something preventing me from doing so? I've tried other addresses and ports (192.168.1.2 and port 47346) but with no success. Here's a gdb printout of my sockaddr_in: $1 = { sin_len = 0 '\0', sin_family = 2 '\002', sin_port = 47346, sin_addr = { s_addr = 3232235778 }, sin_zero = "???\000\000??" }

• Very basic question about Hadoop and compressed input files

  - by Luis Sisamon

  I have started to look into Hadoop. If my understanding is right i could process a very big file and it would get split over different nodes, however if the file is compressed then the file could not be split and wold need to be processed by a single node (effectively destroying the advantage of running a mapreduce ver a cluster of parallel machines). My question is, assuming the above is correct, is it possible to split a large file manually in fixed-size chunks, or daily chunks, compress them and then pass a list of compressed input files to perform a mapreduce?

• Is Prince the best way to PDF in Ruby on Rails?

  - by Angela

  After several Google searches, it appears that the way to create PDF's in Rails from HTML and CSS (versus a new markup language) is to use Prince. With licensing at $3800 for my non-big-commercial app, I'm wondering if this is, in fact, consensus or people have an alternative they can share the what's and how's.

• What's faster Model.get(keys) or Model.get_by_id(ids, parent=None)

  - by WooYek

  I'm wondering is there a difference in terms of computing cost for the Model.get(keys) and Model.get_by_id(ids, parent=None) methods? Is there a server side computing advantage of using numeric id's over encoded string keys, or other way around? How big is the difference? PS. Sorry, if it's a dupe. I'm sure I read an article about it, but I cannot find it now.

Which technology did you use right away: AOP, complex Hibernate...

• Several ifstream vs. ifstream + constant seeking

  - by SpyBot

  I'm writing an external merge sort. It works like that: read k chunks from big file, sort them in memory, perform k-way merge, done. So I need to sequentially read from different portions of the file during the k-way merge phase. What's the best way to do that: several ifstreams or one ifstream and seeking? Also, is there a library for easy async IO?

  I try to setup UltraMon with a really big width and height for my Safari on Windows.

I want UltraMon not to change my width and height, even if they are bigger than the screen resolution.

• Finding a small image in a bigger one

  - by tur1ng

  Given an image with a large dimension ( 1.000 x 1.000). What is a good approach to find a small image (e.g. 50 x 50) in the big one? The smaller image can be rotated and differ in the size, but only with a 1:1 ratio. It's not related to any programming language - I'm just interested in pattern recognition. Thank you.

• Is it possible to avoid Focus on SplitContainer?

  - by Filini

  The WinForm SplitContainer gets the focus when it's dragged or clicked, while the Splitter does not. The side-effect of this, is that dragging a SplitContainer bar fires Leave/Validate on other controls, and I need to avoid this. I already tried setting TabStop and CausesValidation to False, but with no success. Is there a way to stop the SplitContainer from getting focused? (not a big deal, I can still use the old Splitter, but I lose some nice VS properties...)

• Efective way to avoid integer overflow when multiplying?

  - by Jonathan

  Hi, I'm working on a hash function which gets a string as input. Right now I'm doing a loop and inside the hash (an int variable) is being multiplied by a value and then the ASCII code for the current character is added to the mix. hash = hash * seed + string[i] But sometimes, if the string is big enough there is an integer overflow there, what can I do to avoid it while maintaining the same hash structure? Maybe a bit operation included inside the loop?
