  • Targus USB-to-RS232 not working with Linux?

    - by Ethan Leroy
    I have the Targus PA088 USB to RS232 converter, but it seems that it does not work with linux. Its RX and TX lights are flashing, but I can't see the data in minicom/picocom. When using it with Windows and hterm, everything's fine. Any idea what could be the problem? Additional info: When I plug in the adapter, I can see the following messages in /var/log/messages.log Nov 25 01:47:31 localhost kernel: [ 831.787066] usb 2-1.1: new full speed USB device number 5 using ehci_hcd Nov 25 01:47:32 localhost kernel: [ 832.554810] mct_u232 2-1.1:1.0: MCT U232 converter detected Nov 25 01:47:32 localhost kernel: [ 832.555002] usb 2-1.1: MCT U232 converter now attached to ttyUSB0 Nov 25 01:47:32 localhost mtp-probe: checking bus 2, device 5: "/sys/devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.1" Nov 25 01:47:32 localhost mtp-probe: bus: 2, device: 5 was not an MTP device

  • Can you get to a command line on the iPhone?

    - by Ethan
    I'm not even sure why I'd want to do this. I guess I'm just curious. Is there a way to get to some kind console, command line, or text-based UI on the iPhone? I'm referring to accessing the iPhone system itself, poking around in the directories, opening files in something akin to vi, that sort of thing.

    whenever I want to install a new vim script to the linux server I'm working in , my typical workflow is as the following: surf the plugin's homepage in vim online using fireXXXX download a right version of the plugin to my laptop by click some highlighted link upload the downloaded plugin from my laptop to linux server using winscp which is really inconvenient.

  • Installing SSL certs with nginx on Amazon EC2

    - by Ethan
    I finally got a cert from an authority and am struggling to get things working. I've created the appropriate combined certificate (personal + intermediate + root) and nginx is pointing to it. I got an elastic IP and connected it to my EC2 instance. My DNS records point to that IP. But when I point the browser to the hostname, I get the standard "Connection Untrusted" bit, with ssl_error_bad_cert_domain. Port 443 is open - I can get to the site over https if I ignore the warning. Weird thing is, under technical details, it lists the domain I tried to access as valid! When I try and diagnose with ssl testing sites, they don't even detect a certificate! What am I missing here? domain is yanlj.coinculture.info. Note I've got coinculture.info running on a home server without a dedicated IP and have the same problem, but I'll be moving that to the same EC2 instance as soon as I figure this thing out. I thought the elastic IP would solve things but it hasn't

  • How do you make a randomly generated url address after form input?

    - by pmal10

  • Transactions in codeigniter with multiple tables.

    - by Ethan
    Hey SO, I'm new to transactions in general, but especially with CodeIgniter. I'm using InnoDB and everything, but my transactions aren't rolling back when I want them to. Here's my code (slightly simplified). $dog_db = $this->load->database('dog', true); $dog_db->trans_begin(); $dog_id = $this->dogs->insert($new_dog); //Gets primary key of insert if(!$dog_id) { $dog_db->trans_rollback(); throw new Exception('We have had an error trying to add this dog. Please go back and try again.'); } $new_review['dog_id'] = $dog_id; $new_review['user_id'] = $user_id; $new_review['date_added'] = time(); if(!$this->reviews->insert($new_review)) //If the insert fails { $dog_db->trans_rollback(); throw new Exception('We have had an error trying to add this dog. Please go back and try again.'); } //ADD DESCRIPTION $new_description['description'] = $add_dog['description']; $new_description['dog_id'] = $dog_id; $new_description['user_id'] = $user_id; $new_description['date_added'] = time(); if(!$this->descriptions->insert($new_description)) { $dog_db->trans_rollback(); throw new Exception('We have had an error trying to add this dog. Please go back and try again.'); } $booze_db->trans_rollback(); //THIS IS JUST TO SEE IF IT WORKS throw new Exception('We have had an error trying to add this dog. Please go back and try again.'); $booze_db->trans_commit(); } catch(Exception $e) { echo $e->getMessage(); } I'm not getting any error messages, but it's not rolling back either. It should roll back at that final trans_rollback right before the commit. My models are all on the "dog" database, so I think that the transaction would carry into the models' functions. Maybe you just can't use models like this. Any help would be greatly appreciated! Thanks!

  • Using ExpressionEngine or Joomla templates inside a pre-existing page?

    - by Ethan
    Hey SO, So I'm new to both Joomla and Expression Engine, and want to know if I can use it like I'd like. I've already made a full site, and would like to integrate blogging into the site. The site is on CodeIgniter. Is there a way that I could create a form template for submitting a post which would then save to my Joomla/CodeIgniter DB. Then, on a different page, use a different Joomla/CodeIgniter template to display the blog in the form I would like. Note that this wouldn't necessarily be powered by EE or Joomla. From what I understand, and from all the examples I've seen, you have to make the html of the entire page inside of their templates. At worst, if neither work, is there anything I can use to do this? Thanks!

  • Getting uninitialized constant error when trying to run tests

    - by Ethan
    I just updated all my gems and I'm finding that I'm getting errors when trying to run Test::Unit tests. I'm getting the error copied below. That comes from creating new, empty Rails project, scaffolding a simple model, and running rake test. Tried Googling "uninitialized constant" and TestResultFailureSupport. The only thing I found was this bug report from 2007. I'm using OS X. These are the gems that I updated right before the tests stopped working: $ sudo gem outdated Password: RedCloth (4.2.1 < 4.2.2) RubyInline (3.8.1 < 3.8.2) ZenTest (4.1.1 < 4.1.3) bluecloth (2.0.4 < 2.0.5) capistrano (2.5.5 < 2.5.8) haml (2.0.9 < 2.2.1) hoe (2.2.0 < 2.3.2) json (1.1.6 < 1.1.7) mocha (0.9.5 < 0.9.7) rest-client (1.0.2 < 1.0.3) thoughtbot-factory_girl (1.2.1 < 1.2.2) thoughtbot-shoulda (2.10.1 < 2.10.2) Has anyone else seen this issue? Any troubleshooting suggestions? UPDATE On a hunch I downgraded ZenTest from 4.1.3 back to 4.1.1 and now everything works again. Still curious to know if anyone else has seen this or has any interesting comments or insights. $ rake test (in /Users/me/foo) /usr/local/bin/ruby -I"lib:test" "/usr/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake/rake_test_loader.rb" "test/unit/helpers/users_helper_test.rb" "test/unit/user_test.rb" /usr/local/lib/ruby/gems/1.8/gems/activesupport-2.3.2/lib/active_support/dependencies.rb:105:in `const_missing': uninitialized constant Test::Unit::TestResult::TestResultFailureSupport (NameError) from /usr/local/lib/ruby/gems/1.8/gems/test-unit-2.0.2/lib/test/unit/testresult.rb:28 from /usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require' from /usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `require' from /usr/local/lib/ruby/gems/1.8/gems/activesupport-2.3.2/lib/active_support/dependencies.rb:158:in `require' from /usr/local/lib/ruby/gems/1.8/gems/test-unit-2.0.2/lib/test/unit/ui/testrunnermediator.rb:9 from /usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require' from /usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `require' from /usr/local/lib/ruby/gems/1.8/gems/activesupport-2.3.2/lib/active_support/dependencies.rb:158:in `require' ... 6 levels... from /usr/local/lib/ruby/1.8/test/unit/autorunner.rb:214:in `run' from /usr/local/lib/ruby/1.8/test/unit/autorunner.rb:12:in `run' from /usr/local/lib/ruby/1.8/test/unit.rb:278 from /usr/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake/rake_test_loader.rb:5 /usr/local/bin/ruby -I"lib:test" "/usr/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake/rake_test_loader.rb" "test/functional/users_controller_test.rb"

  • DataMapper Dates

  • ServiceRoute + WebServiceHostFactory kills WSDL generation? How to create extensionless WCF service

    - by Ethan J. Brown
    I'm trying to use extenionless / .svc-less WCF services. Can anyone else confirm or deny the issue I'm experiencing? I use routing in code, and do this in Application_Start of global.asax.cs: RouteTable.Routes.Add(new ServiceRoute("Data", new WebServiceHostFactory(), typeof(DataDips))); I have tested in both IIS 6 and IIS 7.5 and I can use the service just fine (ie my extensionless handler is correctly configured for ASP.NET). However, metadata generation is totally screwed up. I can hit my /mex endpoint with the WCF Test Client (and I presume svcutil.exe) -- but the ?wsdl generation you typically get with .svc is toast. I can't hit it with a browser (get 400 bad request), I can't hit it with wsdl.exe, etc. Metadata generation is configured correctly in web.config. This is a problem of course, because the service is exposed as basicHttpBinding so that an old style ASMX client can get to it. But of course, the client can't generate the proxy without a WSDL description. If I instead use serviceActivation routing in config like this, rather than registering a route in code: <serviceHostingEnvironment aspNetCompatibilityEnabled="true"> <serviceActivations> <add relativeAddress="Data.svc" service="DataDips" /> </serviceActivations> </serviceHostingEnvironment> Then voila... it works. But then I don't have a clean extensionless url. If I change relativeAddress from Data.svc to Data, then I get a configuration exception as this is not supported by config. (Must use an extension registered to WCF). I've also attempted to use this code in conjunction with the above config: RouteTable.Routes.MapPageRoute("","Data/{*data}","~/Data.svc/{*data}",false); My thinking is that I can just point the extensionless url at the configured .svc url. This doesn't work -- the /Data.svc continues to work, but /Data returns a 404. Anyone with any bright ideas?

  • GWT and java.io.Serializable

    - by Ethan Leroy
    Hello, In my GWT app I have the following model class: import com.google.gwt.user.client.rpc.IsSerializable; public class TestEntity implements IsSerializable { public String testString; } This class implements the GWT custom IsSerializable marker interface - which I really don't like, because I use my model classes not only for GWT. So I prefer java.io.Serializable. But if I modify the class to implement Serializable instead of IsSerializable, the GWT RPC mechanism doesn't work anymore. I don't get an error on the server side, but on the client AsyncCallback.onFailure is invoked. I am using... GWT 1.7.0. Spring 2.5.6.SEC01 Spring and GWT are configured as described here.

  • how to temporarily set makeprg in vim

    - by Haiyuan Zhang
    In the normal case I use vim's make utility I will set makeprg to the Makefile of the project I'm currently working for. Since usually the project will last for weeks or even longer, I don't need to change the setting of makeprg very often . But sometimes I need to write some "foobar" code either for practicing my c++ skill or for prototyping some primitive ideas in my mind. So whenever I switch to the "foobar" mode of vim usage, I need to comments the original makeprg setting add the new setting as following : au FileType c set makeprg=gcc\ % au FileType cpp set makeprg=g++\ % which is really very very inconvenient . when I back to the "normal project mode" of vim usage, I need to change back to the original setting . back and forth .... what I want to know from you guys is that : is it possible to make the setting of makeprg temporarily . for example , define a function in which first set a local value of makeprg and then call make before return form the function call automatically restore makeprg to the value before the function call.

  • CSS Margins Increase with H1 Length

    Consider the following markup: <!DOCTYPE html> <html> <head> <title>Test Page</title> <link href="screen.css" rel="stylesheet" /> </head> <body> <h1>Test</h1> <h3>Description</h3> </body> </html> And the CSS: h3{ margin-top: -25px; } Now, I want the H3 to have a margin-left of however long H1 is, and it is consistently 20px away. So, if I have a H1 block of 200px long, then H3 would have a margin-left of 220px, and so on and so forth. How would I do this?

  • Matching math expression with regular expression?

Any idea? If there is better solution than regular expression, I'll accept as well. But regex is preferred.

Is there an easy way i didnt see, or are boosts ptr_vector the false choice for this case? Thanks in advance.
