  • How can I transform this haml into a table?

    - by mmr
    I have the following haml code: - @theLinks.each_index do |x| %br %form{:action=>'/Download', :method=>"post",:enctype=>"multipart/form-data"} %input{:type=>"submit", :name=>"#{@theLinks[x].url}", :value=>"Name: #{@theLinks[x].Name} Study Time: #{@theLinks[x].studyTime} Comments: #{@theLinks[x].comments}"} Basically, for each person, list the time they participated in a study and the comments on the study. Right now, this renders as a set of buttons. I'd like to render it as a table, with each row clickable in the same way (ie, using the 'post' method, so that only the haml file has to be edited without touching the rest of the files). Ideally, I'd also like to be able to sort the table by name, time, or comments, but that might be getting ahead of myself. So how can I change this list of buttons into a table with clickable rows?

  • How does memory management in Java and C# differ?

    - by David Johnstone
    I was reading through 2010 CWE/SANS Top 25 Most Dangerous Programming Errors and one of the entries is for Buffer Copy without Checking Size of Input. It suggests using a language with features to prevent or mitigate this problem, and says: For example, many languages that perform their own memory management, such as Java and Perl, are not subject to buffer overflows. Other languages, such as Ada and C#, typically provide overflow protection, but the protection can be disabled by the programmer. I was not aware that Java and C# differed in any meaningful way with regard to memory management. How is it that Java is not subject to buffer overflows, while C# only protects against overflows? And how is it possible to disable this protection in C#?

  • Installing Ruby On Rails - Issues with gem (and no RVM)

    - by JXPheonix
    I'm having this issue whenever i run "gem install rails": usr/local/lib/ruby/1.9.1/yaml.rb:56:in `<top (required)>': It seems your ruby installation is missing psych (for YAML output). To eliminate this warning, please install libyaml and reinstall your ruby. ERROR: Loading command: install (LoadError) cannot load such file -- zlib ERROR: While executing gem ... (NameError) uninitialized constant Gem::Commands::InstallCommand Ruby and Rubygems were both installed from source. I've installed libyaml from source and from apt-get. I'm running ubuntu 12.04. I am NOT running RVM as far as I know (trying "rvm" returns "bla bla bla not installed apt-get". I'm pretty sure this speaks of 2 separate issues but I need solutions to both. Thanks.

  • Malloc to a CGPoint Pointer throwing EXC_BAD_ACCESS when accessing

    - by kdbdallas
    I am trying to use a snippet of code from a Apple programming guide, and I am getting a EXC_BAD_ACCESS when trying to pass a pointer to a function, right after doing a malloc. (For Reference: iPhone Application Programming Guide: Event Handling - Listing 3-6) The code in question is really simple: CFMutableDictionaryRef touchBeginPoints; UITouch *touch; .... CGPoint *point = (CGPoint *)CFDictionaryGetValue(touchBeginPoints, touch); if (point == NULL) { point = (CGPoint *)malloc(sizeof(CGPoint)); CFDictionarySetValue(touchBeginPoints, touch, point); } Now when the program goes into the if statement it assigns the 'output' of malloc into the point variable/pointer. Then when it tries to pass point into the CFDictionarySetValue function it crashes the application with: Program received signal: “EXC_BAD_ACCESS”. Someone suggested not doing the malloc and pass the point var/pointer as: &point, however that still gave me a EXC_BAD_ACCESS. What I am (and it looks like Apple) doing wrong??? Thanks in advance.

  • Use only some parts of Django?

    - by Hanno Fietz
    I like Django, but for a particular application I would like to use only parts of it, but I'm not familiar enough with how Django works on the inside, so maybe someone can point me into the right direction as to what I have to check out. Specifically, I want to use: The models and database abstraction The caching API, although I want to avoid database lookups by caching, not HTML generation, and since the caching framework in Django is intended for the latter, I'm not sure yet whether that's really appropriate. I would not use: Templating urlconfigs Or, more exactly, I'm neither using HTTP nor HTML. So basically, I have a different input / output chain than usual. Can this work? My personal killer feature in Django is the Object / database mapping that I can do with the models, so if there's another technology (doesn't have to be Python, I'm in the design phase and I'm pretty agnostic about languages and platforms) that gives me the same abilities, that would be great, too.

  • GnuPG Shell Script - Refuses to read password

    - by OopsForgotMyOtherUserName
    The script below used to work on Mac OS X, but, since moving it to Ubuntu, it doesn't seem to read from the password file at all. Even when I run it from the command line, no matter what I do, I get a popup prompt asking me for the password. As this will run via cron, I don't want this to happen... I want it to read the password from the file with no prompt. To note, I did try using passphrase-fd and passphrase-file, neither of which worked... #!/bin/sh p=$(<pass.txt) set -- $p pass_phrase=$1 destination="/var/www/decrypted" cd /var/sl_bin/ for FILE in *.pgp; do FILENAME=${FILE%.pgp} gpg --passphrase "$pass_phrase" --output "$destination/$FILENAME" --decrypt "$FILE" rm -f $FILE done

  • sending control+c (SIGINT) to NSPIPE in objective-c

    - by Ron
    Hello, I am trying to terminate an openvpn task, spawned via NSTask. My question: Should I send ctrl+c (SIGINT) to the input NSPipe for my NSTask? inputPipe = [NSPipe pipe]; taskInput = [inputPipe fileHandleForWriting]; NSString dataString = @"\cC"; [taskInput writeData:[dataString dataUsingEncoding: [NSString defaultCStringEncoding]]]; Alternatively, I was thinking about using kill( pid, SIGINT ); but it would be much more complicated since the process ID has to be determined via a detour ([task processIdentifier] does not help here) - the original NSTask calls: /bin/bash -c sudo -S | mypassword .... That's not nice, I know but it is only called once and the sudo password has been entered in that case already. thanks for any suggestions/opinions/etc. Ron

  • PHP urlize function

    - by Maxime
    Hello guys, I'm using this function on my website to transform user input into acceptable URL: function urlize($url) { $search = array('/[^a-z0-9]/', '/--+/', '/^-+/', '/-+$/' ); $replace = array( '-', '-', '', ''); return preg_replace($search, $replace, utf2ascii($url)); } function utf2ascii($string) { $iso88591 = "\\xE0\\xE1\\xE2\\xE3\\xE4\\xE5\\xE6\\xE7"; $iso88591 .= "\\xE8\\xE9\\xEA\\xEB\\xEC\\xED\\xEE\\xEF"; $iso88591 .= "\\xF0\\xF1\\xF2\\xF3\\xF4\\xF5\\xF6\\xF7"; $iso88591 .= "\\xF8\\xF9\\xFA\\xFB\\xFC\\xFD\\xFE\\xFF"; $ascii = "aaaaaaaceeeeiiiidnooooooouuuuyyy"; return strtr(mb_strtolower(utf8_decode($string), 'ISO-8859-1'),$iso88591,$ascii); } I'm having a problem with it though, with numbers. For some reason when I try: echo urlize("test 23342"); I get "test-eiioe". Why is that and how can I fix it? Thank you very much!

  • ASP.NET MVC & ADO.NET Entity Framework clientside validation

    - by JK
    Using aspnet mvc2 with the model auto-generated by entity framework: Is it possible to tell entity framework to auto-annotate all fields? eg: If database field says not null then add [Required] If DB field is a nvarchar(x) then add [StringLength(x)] And so on? What if the field name contains the string "email" eg CustomerEmail - can I get EF to auto-annotate that with an appropriate annotation ([Regex()] maybe) As I understand it, if the model fields are annotated, and I use both Html.ValidationMessageFor() and use if (ModelState.IsValid) in my controller, then that is all I need to do to have basic clientside input validation working? Thanks

  • Can't get expand_aliases to take effect

    - by sachmet
    I can't get expand_aliases to take effect in bash. I've tried a lot of different things, and nothing works. Here's the simple test case: /bin/bash -c 'shopt -s expand_aliases; alias cdtmp="cd /tmp"; alias; cdtmp; pwd;' And the output: $ /bin/bash -c 'shopt -s expand_aliases; alias cdtmp="cd /tmp"; alias; cdtmp; pwd;' alias cdtmp='cd /tmp' /bin/bash: cdtmp: command not found /home/user $ /bin/bash --version GNU bash, version 3.2.25(1)-release (i686-redhat-linux-gnu) Copyright (C) 2005 Free Software Foundation, Inc.

  • Check if key is pressed using python (a daemon in the background)

    - by Nazarius Kappertaal
    I've created a python script in which an event needs to be executed each time I press the Super (or WinKey) on my keyboard. How can one achieve this without the python process being "focused" - as it is running in the background waiting for the key to be pressed to execute the event? I've seen a lot of posts around the web showing me how to read input - but they have all required one to have the process "focused" and none have showed me how to capture the Super (or WinKey) using a python script. I'm running Ubuntu 9.10.

  • Memcache won't flush or clear memory

    - by pedalpete
    I've been trying to clear my memcache as I'm noticing the storage taking up almost 30% of server memory when using ps -aux. So I ran the following php code. $memcache = new Memcache; $memcache-connect("localhost",11211); $memcache-flush(); print_r($memcache-getStats()); This results in the output of ( [pid] = 4936 [uptime] = 27318915 [time] = 1255318611 [version] = 1.2.2 [pointer_size] = 64 [rusage_user] = 9.659531 [rusage_system] = 49.770433 [curr_items] = 57864 [total_items] = 128246 [bytes] = 1931734247 [curr_connections] = 1 [total_connections] = 128488 [connection_structures] = 17 [cmd_get] = 170288 [cmd_set] = 128246 [get_hits] = 45464 [get_misses] = 124824 [evictions] = 1009 [bytes_read] = 5607431213 [bytes_written] = 1806543589 [limit_maxbytes] = 2147483648 [threads] = 1 ) This should be fairly basic, but clearly, I'm missing something.

  • Outlook Macro not executing

    - by Tim
    Hello all, we are using an an outlook macro for incoming emails to unzip the attachments, log them in sql server and copy them to a special working folder where a windows service processes them. The problems are: the user must be logged in at the server otherwise the macro wont run. I think there is no workaround for this. whenever a modal dialog pops up in outlook and waits for user input, the macro wont execute either (f.e. AutoArchive) I have stopped AutoArchiving all x-days in the options. Because its a productive environment, are there other possible windows preventing the macro to execute, which i must disable now? Our outlook-macro solution surely is not the best because of above problems. Are there better alternatives to read emails, unzip attachments and move them to a working folder? My language is VB.Net and server OS is windows 2008. Regards, Tim

  • PostgreSQL - CREATE INDEX

    - by mocopera
    Hi! I'm working with PostgreSQL to create some data types written in C. For example, I have: typedef struct Point3D { char id[50]; double x; double y; double z; } Point3D; The input and output functions are working properly. But the problem is the following: Every id of Point3D must be unique (and can be NULL), so I have decided to create an unique index on this field id, but is that possible? I'm thinking in something like this: create unique index test_point3d_idx on test_point3d (( getID(columname) )); where getID returns the field ID of columname. But I need to implement getID and I am really blocked. Any advice?

  • How can I compile a Perl script inside a running Perl session?

    - by Joel
    I have a Perl script that takes user input and creates another script that will be run at a later date. I'm currently going through and writing tests for these scripts and one of the tests that I would like to perform is checking if the generated script compiles successfully (e.g. perl -c <script>.) Is there a way that I can have Perl perform a compile on the generated script without having to spawn another Perl process? I've tried searching for answers, but searches just turn up information about compiling Perl scripts into executable programs.

  • iPhone: fast hash function for storing web images (url) as files (hashed filenames)

    - by Stefan Klumpp
    What is a fast hash function available for the iPhone to hash web urls (images)? I'd like to store the cached web image as a file with a hash as the filename, because I suppose the raw web url could contain strange characters that could cause problems on the file system. The hash function doesn't need to be cryptographic, but it definitely needs to be fast. Example: Input: http://www.calumetphoto.com/files/iccprofiles/icc-test-image.jpg Output: 3573ed9c4d3a5b093355b2d8a1468509 This was done by using MD5(), but since I don't know much about that topic I don't know if it is overkill (- slow).

    We are using Crystal Reports to generate pdf's of customer bills (from a CR template). It works fine except the engine seems to be adding the letter "i" to random words in the output. Certain alignment problems are also evident (words overlapping etc). Standard fonts are being used. We are using .net 4 and C# linked to the 10.5 CR assemblies. Latest version of Adobe Acrobat reader is installed on the server. We have now tried this via 12.2 CR assemblies with the same results. We have also tried multiple .rpt files with the same results.

  • How can I use images provided by the iPhone OS?

    - by Topher Fangio
    Hello all, First, let me state what brought this question about: I saw the green checkmark icon in this post and I would like to use it in my own application. However, since it looks so much like the UITableViewCellAccessoryDetailDisclosureButton my assumption is that this green checkmark icon is provided by the iPhone OS in some form or fashion. So, my question is: how can I use the green checkmark icon and/or other OS-provided images in my own applications? As a side question: where can I find a list of the OS-provided images (if they even exist)? Thanks very much for any input :-)
