  • Perl throws an error message about syntax

    - by Ben Dauphinee
    So, building off a question about string matching (this thread), I am working on implementing that info in solution 3 into a working solution to the problem I am working on. However, I am getting errors, specifically about this line of the below function: next if @$args->{search_in} !~ /@$cur[1]/; syntax error at ./db_index.pl line 16, near "next " My question as a perl newbie is what am I doing wrong here? sub search_for_key { my ($args) = @_; foreach $row(@{$args->{search_ary}}){ print "@$row[0] : @$row[1]\n"; } my $thiskey = NULL; foreach $cur (@{$args->{search_ary}}){ print "\n" . @$cur[1] . "\n" next if @$args->{search_in} !~ /@$cur[1]/; $thiskey = @$cur[0]; last; } return $thiskey; }

  • ANSI SQL question - how to insert or update a record if it already exists?

    - by morpheous
    Although I am using mySQL (for now), I dont want any DB specific SQL. I am trying to insert a record if it doesn't exist, and update a field if it does exist. I want to use ANSI SQL. The table looks something like this: create table test_table (id int, name varchar(16), weight double) ; //test data insert into test_table (id, name, weight) values(1,'homer', 900); insert into test_table (id, name, weight) values(2,'marge', 85); insert into test_table (id, name, weight) values(3,'bart', 25); insert into test_table (id, name, weight) values(4,'lisa', 15); If the record exists, I want to update the weight (increase by say 10)

  • tcpdf - HTML table showing up way too small

    - by LinuxGnut
    Hi folks. I'm using tcpdf (http://www.tcpdf.org/) to generate PDFs of some tables and images. The images are loaded without an issue, but I'm having issues with the writeHTML() function. I can't seem to control the font sizes or table width/height through the HTML, so I end up with a tiny, tiny, tiny table that you have to print of and squint at to even attempt reading. I've tried editing the table itself, CSS, even putting the table itself inside an h1, but nothing is changing the font size. I have the font size in tcpdf set to 16, but this also has no affect. Has anyone else run into this issue?

  • CUDA SDK compilation error

    - by ZeroDivide
    I am in the process of setting up a CUDA workstation. Platform specs: Intel Core 2 Duo Nvidia GTX 280 Fedora 10 GCC version 4.3.2 I have installed the developer driver, toolkit, and the SDK. When I try to compile the SDK example code I get the following errors: make[1]: * [obj/i386/release/cutil.cpp.o] Error 1 make: * [lib/libcutil.so] Error 2 I think this means that I am missing a library file but I'm not sure.

  • Large Scale VHDL techniques

    - by oxinabox.ucc.asn.au
    I'm thinking about implimenting a 16 bit CPU in VHDL. A simplish CPU. ADD, MULS, NEG, BitShift, JUMP, Relitive Jump, BREQ, Relitive BREQ, i don't know somethign along these lines Probably all only working with 16bit operands. I might even cut it down and use only a single operand and a accumulator. With Some status regitsters, Carry, Zero, Neg (unless i use a Accumlator), I know how to design all the parts from logic gates, and plan to build them up from first priciples, So for my ALU I'll need to 'build' a ADDer, proably a Carry Look ahead, group adder, this adder it self is make up oa a couple of parts, wich are themselves made up of a couple of parts. Anyway, my problem is not the CPU design, or the VHDL (i know the language, more or less). It's how i should keep things organised. How should I use packages, How should I name my processes and port maps? (i've never seen the benifit of naming the port maps, or processes)

  • Difference between BOOST_CHECK_CLOSE and BOOST_CHECK_CLOSE_FRACTION?

    - by Rhys Ulerich
    Can anyone describe the difference in behavior between BOOST_CHECK_CLOSE and BOOST_CHECK_CLOSE_FRACTION? The documentation implies the that both macros treat their third parameter identically, which makes me suspect the documentation is wrong. In particular, BOOST_CHECK_CLOSE_FRACTION gives me some odd looking results: error in "...": difference between *expected{0} and *actual{-1.7763568394002506e-16} exceeds 9.9999999999999995e-07 Is there a gotcha because I expect a zero result? I've not been successful at reading through the underlying macro declarations. Please note BOOST_CHECK_SMALL isn't appropriate for my use case (comparing two vectors after a linear algebra operation).

  • Logging into table in MS SQL trigger

    - by Martin
    I am coding MS SQL 2005 trigger. I want to make some logging during trigger execution, using INSERT statement into my log table. When there occurs error during execution, I want to raise error and cancel action that cause trigger execution, but not to lose log records. What is the best way to achieve this? Now my trigger logs everything except situation when there is error - because of ROLLBACK. RAISERROR statement is needed in order to inform calling program about error. Now, my error handling code looks like: if (@err = 1) begin INSERT INTO dbo.log(date, entry) SELECT getdate(), 'ERROR: ' + out from #output RAISERROR (@msg, 16, 1) rollback transaction return end

  • [C] Signed Hexadecimal string to long int function

    - by Ben
    I am trying to convert a 24bit Hexadecimal string (6 characters) signed in two's complement to a long int in C. This is the function I have come up with: long int hex2li (char string[]) { char *pEnd; long int result = strtol (string, &pEnd, 16); if (strcmp (pEnd, "") == 0) { if (toupper (string[0]) == 'F') { return result - 16777216; } else { return result; } } return LONG_MIN; } Is it valid? Is there a better way of doing this?

  • pgp key information

    - by calccrypto
    can someone show a description of the information of what a pgp looks like if only the descriptions were there but not the actual information? something like (i dont remember if the values are correct): packet-type[4 bits], total length in bytes[16 bits], packet version type [4 bits], creation-time[32 bits], encryption-algorithm[8 bits], ...,etc,etc ive tried to understand rfc4880, but its tedious and confusing. so far, i am think i have extracted the 4 i wrote above, but i cant seem to get the rest of the information out. can anyone help? i know i can just find some pgp program, but the whole point of this is to allow me to learn how those programs work in the first place

  • Segmentation fault when accessing a PHP page

    - by Justin Ethier
    Sometimes when one of our Apache web servers is restarted, we experience segmentation faults when any PHP page is subsequently accessed. The following line is printed in the httpd error_log: [Wed Jun 16 10:59:33 2010] [notice] child pid 31513 exit signal Segmentation fault (11) There will be one of these lines for each PHP page that is accessed. This appears to happen randomly - the "workaround" to-date is to restart httpd, which eventually fixes the problem (almost always after a single restart). Although we only see this happen rarely, it still happens frequently enough to be of concern. So my question is, why is this happening in the first place? Is this a known bug with the version of Apache / PHP / Linux / etc that we are using? Any ideas? The environment is: Fedora 11 Apache 2.2.15 (Default settings) PHP 5.2.13 I can provide more information if that would help narrow things down, since this error message is rather generic... Any help is appreciated.

  • Why is ARG_MAX not defined via limits.h?

    - by Josh Matthews
    On Fedora Core 7, I'm writing some code that relies on ARG_MAX. However, even if I #include <limits.h>, the constant is still not defined. My investigations show that it's present in <sys/linux/limits.h>, but this is supposed to be portable across Win32/Mac/Linux, so directly including it isn't an option. What's going on here?

  • Does the compiler provides extra stack space for byte-spilling?
