  • Dynamic Attachment Size for Paperclip (Rails)

    - by CalebHC
    Is there anyway to have the validates_attachment_size except a dynamic file size limit? Here's an example: class Document < ActiveRecord::Base belongs_to :folder has_attached_file :document validates_attachment_size :document, :less_than => get_current_file_size_limit private def get_current_file_size_limit 10.megabytes # This will dynamically change end end I've tried this but I keep getting an error saying "unknown method". Lambdas and Procs don't work either. Has anyone ever tried this? Thanks

  • Does the DMA Buffer Size should be same as UART FIFO size?

    - by ddpd
    I have written a driver for a UART in omap4460 panda board running on Linux platform.I have enabled DMA in FIFO mode in UART.My user application transfers 100 bytes of data from user space to kernel buffer(DMA buffer). As soon as the DMA channel is enabled, data from DMA buffer is copied to FIFO which is then transmitted to TSR of UART.Since my FIFO size is 64bytes,only 64 bytes is transmitted to TSR. What should I do to transfer remaining bytes from DMA buffer to FIFO?/ IS there any overflow occuring?

    How do I obtain the number of bytes before allocating the byte size of the array 'handsize' as shown below as the incoming ByteArray data are sent in 3 different sizes. Thanks. BufferedInputStream bais = new BufferedInputStream(requestSocket.getInputStream()); DataInputStream datainput = new DataInputStream(bais); //need to read the number of bytes here before proceeding. byte[] handsize = new byte[bytesize]; datainput.readFully(handsize);

  • Programicaly measure size and way-order of L1 and L2 caches

    - by osgx
    Hello How can I measure programicaly (not query the OS, but measure) the size and order of associativity of L1 and L2 caches (data caches)? Assumtions about system: It has L1 and L2 cache (may be L3 too, may be cache sharing), It may have a hardware prefetch unit (just like P4+), it has a stable clocksource (tickcounter or good HPET for gettimeofday). There are no assumtions about OS (it can be Linux, Windows, smth non-standart), and we can't use posix queries. Language is C. And Compiler optimizations may be disabled.

  • realloc(): invalid next size

    - by Kewley
    I'm having a problem with the realloc function. I'm using C only (so no vector) with LibCurl. The problem I'm having is that I'm getting the following error (realloc(): invalid next size) on the 12th iteration of the write_data function (the function I pass to Curl as a callback, it is called each time libcurl has some data to pass back (data is passed in chunks) ). Trace: Source: http://pastebin.com/WBWhV5fr Thanks in advance,

  • Problems with JQuery's Droppable Tolerance 'fit' feature when using the same size divs

    - by Chris
    Hi I'm just wondering if anybody else can manage to get the tolerance:'fit' option to work when using the 'droppable' feature in jQuery's UI? I want to call a function only when the draggable div is dropped perfectly onto a droppable div. Both divs are the same size and I'm using snapMode:outer to help the end user. I simply cannot get it to work with 'fit'. Works perfectly with 'intersect'. Would really appreciate some help. Thanks Chris

  • array size for extendible hashing

    - by Phenom
    If I want to use extendible hashing to store a maximum of 100 records, then what is the minimum array size that I need? I am guessing that an array of 100 would be sufficient, but I could be wrong. I also suspect that I can use a smaller array.

  • mysql innodb max size of transaction

    - by chris
    Using mysql 5.1.41 and innodb I'm doing some data import, but can't use load data infile, so I'm manually issuing insert statements. I found that it's much faster to disable auto commit and issue say, 100 insert statements and then commit, instead of the implicit commit after each insert. It got me thinking, what limits are there to how much data I can put into a transaction? Is there a limit on the number of statements, or does it have to do with the size in bytes etc...?

  • Optimum size of transaction in Postgres?

    - by Joe
    I'm running a process that does a lot of updates ( 100,000) to a table. I have the choice between putting all the updates in a single transaction or committing transactions every 1000 or so. Ignore for the moment the case where a transaction fails and is aborted. I'm interested in the best size of transaction for memory and speed efficiency.
