• How to hide items under the options from one select box upon selection of an item in another select

  - by jl

  Hi, I am new to jQuery and would like to know how is it possible for me to hide an option in a selection box based on the selection of another selection box. I have 5 selection boxes, this is for the administrator to select the users of a limited criteria. The <options> are create dynamically from the results of a database query and php, and they all have the same <options>. e.g. this is an example of the selection boxes with their option values. userbox1 - Amy, Bosh, Cathy, Daniel, Ethan userbox2 - Amy, Bosh, Cathy, Daniel, Ethan userbox3 - Amy, Bosh, Cathy, Daniel, Ethan userbox4 - Amy, Bosh, Cathy, Daniel, Ethan userbox5 - Amy, Bosh, Cathy, Daniel, Ethan So if the administrator selects Cathy in userbox1, Cathy will be automatically be hidden from the selection on the rest of the userbox. And if the administrator changes his/her mind and reselect another user call Ethan. The userboxes should be able to show the availability of Cathy in the selection. I am not sure is hide/show the correct status to be used in such cases. May I know how is it possible to write the function as stated above? If I am missing some current references, kindly point me to it. Thanks in advance.

• Switched to xubuntu, unity theme wont go away

  - by Ethan

  I got fed up with unity and decided to switch to xubuntu, following the instructions on this thread. Almost everything went well, and I'm much happier with the system. but the window borders from the unity theme are still being used, overriding the xubuntu themes. I've uninstalled all the unity stuff that I can find. I have, however, kept compiz for some of its functionality. I note that if I disable the "Window Decoration" plugin the whole border disappears leaving nothing behind. I want to have normal xubuntu borders. (note that stuff like chromium that handles its own borders displays correctly) I'll gladly give more details, or upload screenshots. Just let me know what information would be helpful. Thanks, Ethan

• How to implement multi relationship in MS SQL?

  - by Ethan

  I’m trying to design a database to use with ASP.net MVC application. Here is the scenario: There are three entities and users can post their comments for each of these different entities. I just wonder how just put one table for Comments and link all other entities to it. Obviously, Comments table needs 3 references (foreign key) to those tables but as you know these foreign keys can’t be null and just one of them can be filled for each row. Is there any better way than implementing three different tables for each entity’s comments? Cheers Ethan

• Any thoughts on Squarespace as a blogging platform?

  - by Ethan

  I'd like to start a blog and I'm leaning towards a hosted, paid platform. I don't want to maintain a Web server. I also don't want the hosting company to put their own ads or branding on my site. Squarespace looks interesting, though kind of pricey. About the same price as TypePad I guess. (I might consider TypePad, but I personally find their UI difficult to use.) WordPress is cheaper but I think they're more known for their software than their hosting. Has anyone tried Squarespace? Are there other options I should consider? Thanks.

• Unauthorized response from Server with API upload

  - by Ethan Shafer

  I'm writing a library in C# to help me develop a Windows application. The library uses the Ubuntu One API. I am able to authenticate and can even make requests to get the Quota (access to Account Admin API) and Volumes (so I know I have access to the Files API at least) Here's what I have as my Upload code: public static void UploadFile(string filename, string filepath) { FileStream file = File.OpenRead(filepath); byte[] bytes = new byte[file.Length]; file.Read(bytes, 0, (int)file.Length); RestClient client = UbuntuOneClients.FilesClient(); RestRequest request = UbuntuOneRequests.BaseRequest(Method.PUT); request.Resource = "/content/~/Ubuntu One/" + filename; request.AddHeader("Content-Length", bytes.Length.ToString()); request.AddParameter("body", bytes, ParameterType.RequestBody); client.ExecuteAsync(request, webResponse => UploadComplete(webResponse)); } Every time I send the request I get an "Unauthorized" response from the server. For now the "/content/~/Ubuntu One/" is hardcoded, but I checked and it is the location of my root volume. Is there anything that I'm missing? UbuntuOneClients.FilesClient() starts the url with "https://files.one.ubuntu.com" UbuntuOneRequests.BaseRequest(Method.{}) is the same requests that I use to send my Quota and Volumes requests, basically just provides all of the parameters needed to authenticate. EDIT:: Here's the BaseRequest() method: public static RestRequest BaseRequest(Method method) { RestRequest request = new RestRequest(method); request.OnBeforeDeserialization = resp => { resp.ContentType = "application/json"; }; request.AddParameter("realm", ""); request.AddParameter("oauth_version", "1.0"); request.AddParameter("oauth_nonce", Guid.NewGuid().ToString()); request.AddParameter("oauth_timestamp", DateTime.Now.ToString()); request.AddParameter("oauth_consumer_key", UbuntuOneRefreshInfo.UbuntuOneInfo.ConsumerKey); request.AddParameter("oauth_token", UbuntuOneRefreshInfo.UbuntuOneInfo.Token); request.AddParameter("oauth_signature_method", "PLAINTEXT"); request.AddParameter("oauth_signature", UbuntuOneRefreshInfo.UbuntuOneInfo.Signature); //request.AddParameter("method", method.ToString()); return request; } and the FilesClient() method: public static RestClient FilesClient() { return (new RestClient("https://files.one.ubuntu.com")); }

• How do you install Firefox plugins from a file?

  - by Ethan

  I would like to install this SQLite Manager plug-in for Firefox on Mac OS X. However, the page advertising the plug-in does not offer the customary "get addon" link (or whatever it's called). There is only the possibility of downloading files. Such as: SQLiteManager_0.5.0b5.xpi How do you use that to install the plug-in?

• Ubuntu boots into command line instead of X.

  - by Ethan Turkeltaub

  I posted this on the Ubuntu forums and they had no good answer. I hope you guys have a solution! On my relatively new install, it's booting into command line instead of X--again. This is the reason I reinstalled in the first place. This has happened to me three times now. So, I boot up and it gets past GRUB, past the glowing Ubuntu option, then it prompts me for my username, then password. I run: startx And that starts the GUI for about a minute, then it runs the GUI login system. To add to the mess, the network-applet is not shown in the panel. Additionally, Chrome will not launch (I ran Firefox from the terminal). What's the problem here?

• How can I format a USB "thumb drive" so it will be readable on OS X and Windows?

  - by Ethan

  I have an OS X system. I want to use it to put some files on a USB drive and then be able to loan the drive to Mac and XP and Vista users so they can get the files off it. I also need to wipe the drive clean first to make sure there's nothing sensitive on it by accident because I'm going to be passing it around. What the name of the filesystem format I want? What's the procedure? Command line operations are fine.

• Automounting Active Directory home drives on a Linux server on login

  - by Ethan

  I've got a Centos 5.7 box authenticating against Active Directory through PBIS Open (the new LikeWise Open), which works well. Now, I'm trying to get the server to automount the user's AD home directory, located at //ad.server.dom/shares/home directories (Yeah, it's a space in the path. I didn't set this up). Each user has a directory in there with the same name as the user. I've tried to get pam_mount working, but it has a series of issues on RedHat and friends, and I can't seem to get that working. The directory does need to be automounted for the server to perform it's role. My reading on automount seems to suggest that there's no way to get it to do it's thing with authentication, though I'm happy to be proved wrong. I've looked at this resource, but it requires version RedHat (thus CentOS) 6 or higher, and newer packages than I have. I can manually (As root) mount the AD directory using the command mount.cifs "//ad.server.dom/Shares/home directories/testuser" /home/local/AD/testuser/nfs_mount/ -o username=testuser and when I log in as testuser, I can see all of the sample files in the nfs_share directory. Any tips towards the right direction would be highly appreciated. This is going to be on a server at a college, so it needs to be fairly stable, and would lead towards more Linux adoption there.

• Excel - Referring to a certain cell based off of data in another

  - by Ethan Brouwer

  I have a spreadsheet where there is one table with the headings: Coordinate, Lat, Long Another with headings Triangle, Coordinate 1, Coordinate 2, Coordinate 3, Area What this is for, is taking the triangles formed by the specified three coordinates' area based off of Girard's theorem, as they are all spherical triangles. I need to take the specific latitude and longitude values from the first table based on the coordinate numbers underneath the three coordinate headings in the second table. I hope this makes sense. Here are pictures detailing what the two tables look like: Table 1 Table 2 Thanks in advance. And I really do hope this makes sense.

• 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

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.

• 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

  - by pmal10

  this is my first time ever posting on a Stackexchange website so I don't know much but my friend, a guy named Ethan know. But, to get on topic, I have a problem or question.

• 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.

• 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?
