  • Generating a scalogram of a signal

    - by Goz
    Hi there, I'm trying to build a scalogram view for my app to see whether there is relevant information we can retrieve from a wavelet transform as opposed to using a spectograms to see what can be retrieved via an FFT. So far I can take a wave form and I can perform the forward wavelet transform on it. However I am lost at the next step. How do I turn this information into power/energy information? I have a set of wave forms at different frequencies but I have, as I say, no frequency information. Can anyone tell me what the next step is for turning this transformed data into a scalogram? Any help would be much appreciated because my google skills are failing me!

  • java keytool question

    - by user384706
    Hi, I created a java keystore programmatically of type jks (i.e. default type). It is initially empty so I created a DSA certificate. keytool -genkey -alias myCert -v -keystore trivial.keystore How can I see the public and private keys? I.e. is there a command that prints the private key of my certificate? I could only find keytool -certreq which in my understanding prints the certificate as a whole: -----BEGIN NEW CERTIFICATE REQUEST----- MIICaTCCAicCAQAwZTELMAkGA1UEBhMCR1IxDzANBgNVBAgTBkdyZWVjZTEPMA0GA1UEBxMGQXRo BQADLwAwLAIUQZbY/3Qq0G26fsBbWiHMbuVd3VICFE+gwtUauYiRbHh0caAtRj3qRTwl -----END NEW CERTIFICATE REQUEST----- I assume this is the whole certificate. How can I see private (or public key) via keytool? Thank you

  • How to make prevent public key inside jar to be saved using Java code

    - by Abhijith V R
    After signing a jar , we can retrieve the public keys from jar using Certificate[] cert = jarentry.getCertificates(); Once certificate is extracted we can save this to a new keystore as trusted cert. Once this is done , then second user can sign any jar using this certificate , isn't ? I want to distribute content as jars , contents will contain properties files for a application init. I want to make sure that an user is not capable to rebuilding the property files using the certificate he extracted from jarentry. In the code which reads the jar contents i am checking that jar is signed with my certificate only and also checking that jar is not tampered with . But the issue came to my mind that if i am able to extract the cerificate from jar then why don;t a third guy ? Can any one help me in this............

  • Google OAuthGetRequestToken returns "signature_invalid"

  • Does Python/Scipy have a firls( ) replacement (i.e. a weighted, least squares, FIR filter design)?

    - by delicasso
    I am porting code from Matlab to Python and am having trouble finding a replacement for the firls( ) routine. It is used for, least-squares linear-phase Finite Impulse Response (FIR) filter design. I looked at scipy.signal and nothing there looked like it would do the trick. Of course I was able to replace my remez and freqz algorithsm, so that's good. On one blog I found an algorithm that implemented this filter without weighting, but I need one with weights. Thanks, David

  • Compass accuracy dilemma

    - by mob1lejunkie
    I need to build compass for my application. From reading the documentation it seems there are two reasonable ways of doing this: Sensor.TYPE_ORIENTATION method: This is the easy way of doing it. The problem with this is it is not accurate. When I compare my reading with Snaptic Compass it is about 10-15 degress off which for my purposes is unacceptable. Sensor.TYPE_ACCELEROMETER, Sensor.TYPE_MAGNETIC_FIELD and getRotationMatrix() in conjunction with remapCoordinateSystem() and getOrientation() method: The documentation says this "is usually more accurate". The problem is regardless of the delay I register with listener the compass goes crazy even when the device is stationary on flat surface. Any suggestions for solving this problem will be greatly appreciated.

  • How can I know if a file has been changed in .NET C#?

    - by Anthony D
    I have an application that requires a secure way to store its configuration. There are users that can change the configuration. I need some sort of signature scheme where I can verify that the config file has not changed with out a valid user. I had thought about using RSA, where the private key is encrypted with the users password, and the public key is used to sign the config. However there is nothing to prevent someone from changing the user file and adding their own public key, thus circumventing my security. Any ideas?

  • Programmatically Determine If An Excel File (.xls) Contains Macros

    - by Gkakk McJkakk
    Is there any way to programmatically determine if an .xls contains macros, without actually opening it in Excel? Also are there any methods to examine which certificate (including timestamp cert) these macros are signed with? Again without using Excel. I'm wondering in particular if there are any strings that always show up in the raw data of an Excel file when macros are present.

  • How to sign XML document or verify XML document signature with C++?

    - by Budda
    Subj. I need to sign/verify in native C++ (no .NET), using private key for signing, public key for verification. I saw few examples on MSDN (http://msdn.microsoft.com/en-us/library/ms761363(VS.85).aspx) that demonstrate how to sign the document with CSP (I don't know what this means). For my case I need to create a "key" from the binary data array... can somebody help me with that? Thank you in advance.

  • How to go about signing text in a verifiable way from within ruby in a simple yet strong & portable

    - by roja
    Guys, I have been looking for a portable method to digitally sign arbitrary text which can be placed in a document and distributed while maintaining its verifiable origin. Here is an example: a = 'some text' a.sign(<private key>) # => <some signature in ASCII format> The contents of a can now be distributed freely. If a receiver wants to check the validity of said text they can do the following: b = 'some text' b.valid(<public key>, <signature supplied with text>) # => true/false Is there any library out there that already offers this kind of functionality? Ruby standard library contains SHA hashing code so at lest there is a portable way to perform the hashing but from that point I am struggling to find anything which fits purpose. Kind Regards, Roja

  • Has anyone succeeded in converting files to the mpg-format that a Sony Digital Camera can play?

    - by user645552
    I'm trying to play a mpeg movie on my Sony Cybershot digital camera, it's from a DV-camera converted to MPEG1. But sony refuses to play it with File error. The only files sony can play are from my previous Sony camera. The other way around gives no problem, the movies the camera takes play on various software media players. Has anyone succeeded in converting files to the mpg-format that a Sony Digital Camera can play?

  • Template function overloading with identical signatures, why does this work?

    - by user1843978
    Minimal program: #include <stdio.h> #include <type_traits> template<typename S, typename T> int foo(typename T::type s) { return 1; } template<typename S, typename T> int foo(S s) { return 2; } int main(int argc, char* argv[]) { int x = 3; printf("%d\n", foo<int, std::enable_if<true, int>>(x)); return 0; } output: 1 Why doesn't this give a compile error? When the template code is generated, wouldn't the functions int foo(typename T::type search) and int foo(S& search) have the same signature? If you change the template function signatures a little bit, it still works (as I would expect given the example above): template<typename S, typename T> void foo(typename T::type s) { printf("a\n"); } template<typename S, typename T> void foo(S s) { printf("b\n"); } Yet this doesn't and yet the only difference is that one has an int signature and the other is defined by the first template parameter. template<typename T> void foo(typename T::type s) { printf("a\n"); } template<typename T> void foo(int s) { printf("b\n"); } I'm using code similar to this for a project I'm working on and I'm afraid that there's a subtly to the language that I'm not understanding that will cause some undefined behavior in certain cases. I should also mention that it does compile on both Clang and in VS11 so I don't think it's just a compiler bug.

  • How to Add a Business Card, or vCard (.vcf) File, to a Signature in Outlook 2013 Without Displaying an Image

    - by Lori Kaufman
    Whenever you add a Business Card to your signature in Outlook 2013, the Signature Editor automatically generates a picture of it and includes that in the signature as well as attaching the .vcf file. However, there is a way to leave out the image. To remove the business card image from your signature but maintain the attached .vcf file, you must make a change to the registry. NOTE: Before making changes to the registry, be sure you back it up. We also recommend creating a restore point you can use to restore your system if something goes wrong. Before changing the registry, we must add the Business Card to the signature and save it so a .vcf file of the contact is created in the Signatures folder. To do this, click the File tab. Click Options in the menu list on the left side of the Account Information screen. On the Outlook Options dialog box, click Mail in the list of options on the left side of the dialog box. On the Mail screen, click Signatures in the Compose messages section. For this example, we will create a new signature to include the .vcf file for your business card without the image. Click New below the Select signature to edit box. Enter a name for the new signature, such as Business Card, and click OK. Enter text in the signature editor and format it the way you want or insert a different image or logo. Click Business Card above the signature editor. Select the contact you want to include in the signature on the Insert Business Card dialog box and click OK. Click Save below the Select signature to edit box. This creates a .vcf file for the business card in the Signatures folder. Click on the business card image in the signature and delete it. You should only see your formatted text or other image or logo in the signature editor. Click OK to save your new signature and close the signature editor. Close Outlook as well. Now, we will open the Registry Editor to add a key and value to indicate where to find the .vcf to include in the signature we just created. If you’re running Windows 8, press the Windows Key + X to open the command menu and select Run. You can also press the Windows Key + R to directly access the Run dialog box. NOTE: In Windows 7, select Run from the Start menu. In the Open edit box on the Run dialog box, enter “regedit” (without the quotes) and click OK. If the User Account Control dialog box displays, click Yes to continue. NOTE: You may not see this dialog box, depending on your User Account Control settings. Navigate to the following registry key: HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Outlook\Signatures Make sure the Signatures key is selected. Select New | String Value from the Edit menu. NOTE: You can also right-click in the empty space in the right pane and select New | String Value from the popup menu. Rename the new value to the name of the Signature you created. For this example, we named the value Business Card. Double-click on the new value. In the Value data edit box on the Edit String dialog box, enter the value indicating the location of the .vcf file to include in the signature. The format is: <signature name>_files\<name of .vcf file> For our example, the Value data should be as follows: Business Card_files\Lori Kaufman The name of the .vcf file is generally the contact name. If you’re not sure of what to enter for the Value data for the new key value, you can check the location and name of the .vcf file. To do this, open the Outlook Options dialog box and access the Mail screen as instructed earlier in this article. However, press and hold the Ctrl key while clicking the Signatures button. The Signatures folder opens in Windows Explorer. There should be a folder in the Signatures folder named after the signature you created with “_files” added to the end. For our example, the folder is named Business Card_files. Open this folder. In this folder, you should see a .vcf file with the name of your contact as the name of the file. For our contact, the file is named Lori Kaufman.vcf. The path to the .vcf file should be the name of the folder for the signature (Business Card_files), followed by a “\”, and the name of the .vcf file without the extension (Lori Kaufman). Putting these names together, you get the path that should be entered as the Value data in the new key you created in the Registry Editor. Business Card_files\Lori Kaufman Once you’ve entered the Value data for the new key, select Exit from the File menu to close the Registry Editor. Open Outlook and click New Email on the Home tab. Click Signature in the Include section of the New Mail Message tab and select your new signature from the drop-down menu. NOTE: If you made the new signature the default signature, it will be automatically inserted into the new mail message. The .vcf file is attached to the email message, but the business card image is not included. All you will see in the body of the email message is the text or other image you included in the signature. You can also choose to include an image of your business card in a signature with no .vcf file attached.

  • How to Assign a Default Signature in Outlook 2013

    - by Lori Kaufman
    If you sign most of your emails the same way, you can easily specify a default signature to automatically insert into new email messages and replies and forwards. This can be done directly in the Signature editor in Outlook 2013. We recently showed you how to create a new signature. You can also create multiple signatures for each email account and define a different default signature for each account. When you change your sending account when composing a new email message, the signature would change automatically as well. NOTE: To have a signature added automatically to new email messages and replies and forwards, you must have a default signature assigned in each email account. If you don’t want a signature in every account, you can create a signature with just a space, a full stop, dashes, or other generic characters. To assign a default signature, open Outlook and click the File tab. Click Options in the menu list on the left side of the Account Information screen. On the Outlook Options dialog box, click Mail in the list of options on the left side of the dialog box. On the Mail screen, click Signatures in the Compose messages section. To change the default signature for an email account, select the account from the E-mail account drop-down list on the top, right side of the dialog box under Choose default signature. Then, select the signature you want to use by default for New messages and for Replies/forwards from the other two drop-down lists. Click OK to accept your changes and close the dialog box. Click OK on the Outlook Options dialog box to close it. You can also access the Signatures and Stationery dialog box from the Message window for new emails and drafts. Click New Email on the Home tab or double-click an email in the Drafts folder to access the Message window. Click Signature in the Include section of the New Mail Message window and select Signatures from the drop-down menu. In the next few days, we will be covering how to use the features of the signature editor next, and then how to insert and change signatures manually, backup and restore your signatures, and modify a signature for use in plain text emails.

  • How to Use the Signature Editor in Outlook 2013

    - by Lori Kaufman
    The Signature Editor in Outlook 2013 allows you to create a custom signature from text, graphics, or business cards. We will show you how to use the various features of the Signature Editor to customize your signatures. To open the Signature Editor, click the File tab and select Options on the left side of the Account Information screen. Then, click Mail on the left side of the Options dialog box and click the Signatures button. For more details, refer to one of the articles mentioned above. Changing the font for your signature is pretty self-explanatory. Select the text for which you want to change the font and select the desired font from the drop-down list. You can also set the justification (left, center, right) for each line of text separately. The drop-down list that reads Automatic by default allows you to change the color of the selected text. Click OK to accept your changes and close the Signatures and Stationery dialog box. To see your signature in an email, click Mail on the Navigation Bar. Click New Email on the Home tab. The Message window displays and your default signature is inserted into the body of the email. NOTE: You shouldn’t use fonts that are not common in your signatures. In order for the recipient to see your signature as you intended, the font you choose also needs to be installed on the recipient’s computer. If the font is not installed, the recipient would see a different font, the wrong characters, or even placeholder characters, which are empty square boxes. Close the Message window using the File tab or the X button in the upper, right corner of the Message window. You can save it as a draft if you want, but it’s not necessary. If you decide to use a font that is not common, a better way to do so would be to create a signature as an image, or logo. Create your image or logo in an image editing program making it the exact size you want to use in your signature. Save the image in a file size as small as possible. The .jpg format works well for pictures, the .png format works well for detailed graphics, and the .gif format works well for simple graphics. The .gif format generally produces the smallest files. To insert an image in your signature, open the Signatures and Stationery dialog box again. Either delete the text currently in the editor, if any, or create a new signature. Then, click the image button on the editor’s toolbar. On the Insert Picture dialog box, navigate to the location of your image, select the file, and click Insert. If you want to insert an image from the web, you must enter the full URL for the image in the File name edit box (instead of the local image filename). For example, http://www.somedomain.com/images/signaturepic.gif. If you want to link to the image at the specified URL, you must also select Link to File from the Insert drop-down list to maintain the URL reference. The image is inserted into the Edit signature box. Click OK to accept your changes and close the Signatures and Stationery dialog box. Create a new email message again. You’ll notice the image you inserted into the signature displays in the body of the message. Close the Message window using the File tab or the X button in the upper, right corner of the Message window. You may want to put a link to a webpage or an email link in your signature. To do this, open the Signatures and Stationery dialog box again. Enter the text to display for the link, highlight the text, and click the Hyperlink button on the editor’s toolbar. On the Insert Hyperlink dialog box, select the type of link from the list on the left and enter the webpage, email, or other type of address in the Address edit box. You can change the text that will display in the signature for the link in the Text to display edit box. Click OK to accept your changes and close the dialog box. The link displays in the editor with the default blue, underlined text. Click OK to accept your changes and close the Signatures and Stationery dialog box. Here’s an example of an email message with a link in the signature. Close the Message window using the File tab or the X button in the upper, right corner of the Message window. You can also insert your contact information into your signature as a Business Card. To do so, click Business Card on the editor’s toolbar. On the Insert Business Card dialog box, select the contact you want to insert as a Business Card. Select a size for the Business Card image from the Size drop-down list. Click OK. The Business Card image displays in the Signature Editor. Click OK to accept your changes and close the Signatures and Stationery dialog box. When you insert a Business Card into your signature, the Business Card image displays in the body of the email message and a .vcf file containing your contact information is attached to the email. This .vcf file can be imported into programs like Outlook that support this format. Close the Message window using the File tab or the X button in the upper, right corner of the Message window. You can also insert your Business Card into your signature without the image or without the .vcf file attached. If you want to provide recipients your contact info in a .vcf file, but don’t want to attach it to every email, you can upload the .vcf file to a location on the internet and add a link to the file, such as “Get my vCard,” in your signature. NOTE: If you want to edit your business card, such as applying a different template to it, you must select a different View other than People for your Contacts folder so you can open the full contact editing window.

  • Is Flash a secure content delivery technology for password protected digital content?

    - by Merkel Fastia
    We are working on a project that would be a competitor to Yudu for online publishing and what we are debating is whether to use Flash for content security protection as Yudu does. See for example "The Testicle Cookbok" for which a limited (3-frame) preview is available before a password is requested by the Flash application running in the browser. Do you see any problems with this approach or could you recommend an alternative technology for password proected digital content?
