• In a virtual machine monitor such as VMware's ESXi Server, how are shadow page tables implemented?

  - by ali01

  My understanding is that VMMs such as VMware's ESXi Server maintain shadow page tables to map virtual page addresses of guest operating systems directly to machine (hardware) addresses. I've been told that shadow page tables are then used directly by the processor's paging hardware to allow memory access in the VM to execute without translation overhead. I would like to understand a bit more about how the shadow page table mechanism works in a VMM. Is my high level understanding above correct? What kind of data structures are used in the implementation of shadow page tables? What is the flow of control from the guest operating system all the way to the hardware? How are memory access translations made for a guest operating system before its shadow page table is populated? How is page sharing supported? Short of straight up reading the source code of an open source VMM, what resources can I look into to learn more about hardware virtualization?

• Getting camera preview data without using a preview callback

  - by velocipedestrian

  I have an app that does some processing to camera preview frames before displaying them to the user. I'm currently using preview callbacks to access the image data, but the problem I have is that the onPreviewFrame() function stops getting called if you start recording video using a MediaRecorder, and I want the processing to continue when video is being recorded. I've tried doing the following: public static Bitmap convertViewToBitmap(View view) { Bitmap bitmap = Bitmap.createBitmap(view.getWidth(),view.getHeight(), Bitmap.Config.ARGB_8888); view.draw(new Canvas(bitmap)); return bitmap; } to convert the preview surface to a bitmap, but when I pass the preview SurfaceView to the function it returns an all-black bitmap (it works when I test it on normal views though). Is there any other way I can access the image data if preview callbacks are not available?

• google contacts api service account oauth2.0 sub user

  - by user3709507

  I am trying to use the Google Contacts API to connect to a user's contact information, on my Google apps domain. Generating an access_token using the gdata api's ContactsService clientlogin function while using the API key for my project works fine, but I would prefer to not store the user's credentials, and from the information I have found that method uses OAuth1.0 So, to use OAuth2.0 I have: Generated a Service Account in the developer's console for my project Granted access to the service account for the scope of https://www.google.com/m8/feeds/ in the Google apps domain admin panel Attempted to generate credentials using SignedJwtAssertionCredentials: credentials = SignedJwtAssertionCredentials( service_account_name=service_account_email, private_key=key_from_p12_file, scope='https://www.google.com/m8/feeds/', sub=user_email') The problem I am running into is that attempting to generate an access token using this method fails. It succeeds in generating the token when I remove the sub parameter, but then that token fails when I try to fetch the user's contacts. Does anyone know why this might be happening?

• How is an SOA architecture really supposed to be implemented?

  - by smaye81

  My project is converting a legacy fat-client desktop application into the web. The database is not changing as a result. Consequently, we are being forced to call external web services to access data in our own database. Couple this with the fact that some parts of our application are allowed to access the database directly through DAOs (a practice that is much faster and easier). The functionality we're supposed to call web services for are what has been deemed necessary for downstream, dependent systems. Is this really how SOA is supposed to work? Admittedly, this is my first foray into the SOA world, but I have to think this is the complete wrong way to go about this.

• JPA in distributed Java EE configuration

  - by sof

  Hello, I'm developing a JEE application to run on Glassfish: Database (javaDB, MS SQL, MySQL or Oracle) EJB layer with JPA (Toplink essentials - from Glassfish) for database access JSF/Icefaces based web UI accessing the EJB layer The application will have a lot of concurrent web client, so I want to run it on different physical servers and use a load-balancer. My problem is now how to keep the applications synchronized. I intend to set up multiple servers, each running Glassfish with my EAR app installed. Whenever on one of the servers data is added to or removed from the database (via JPA, no direct SQL queries), this change should be reflected in the JPA layer on the other servers. I've been looking around for solutions to this, but couldn't find anything I really like (the full Toplink from Oracle claims to have a solution, but don't know). Doing a refresh before every access to a JPA entity could work, but is far from efficient. Are there any patterns, libraries, ... that could help here? Thanks a lot!

• Strange Phantom Local Disks appearing in my drive list...

  - by Paul

  Win7 Home Prem 32 bit I seem to have several phantom Local Disks mapped to different letters, they are of 0 bytes in size? Strangely they do not show up when i view my drives through windows explorer but if i open an application such as ACDSee Pro or MS Word and then go to open a file i can see all these Local Disks mapped to different letters. This means when i plug in my external hard disk it ends up mapped to letter R instead of its usual G which messes up any programs i have pointing to it by default. How did they get there and more importantly how do i get rid of them please??

• Outlook can not recognize PDF v1.7 attachments - those become corrupted after receiving on linux client

  - by SkyRaT

  MS Outlook cannot recognize PDF format 1.7 when sending it as an attachment. Therefore it's sent as: Content-Type: application/pdf; Content-Transfer-Encoding: quoted-printable When receiving such an e-mail under Linux (Thunderbird), the PDF content is being parsed as a plain text and converted. This results in a corrupted file loosing all the bytes 0x0a (LF) which are being removed by the EOL conversion. It's definitely a problem of Outlook which is IMO hard to fix and deploy. Is there a way to fix that on Thunderbird's site?

• Intermittent timeout when connecting to Sql Server, what do I look for?

  - by Will

  Sql Server 2008 Standard 64bit on Windows Server 2008 R2 virtual machine hosted on a Hyper-V server. I'm getting intermittent timeouts when connecting to the server. This happens for both windows and Sql Authentication. May timeout every 2 out of 5 tries in different applications. When the connection times out, I can see (in Profiler) that no connection was made. Firewall is holey, server port is static (good ol' 1433). If I ping /t the server I get a steady connection that wavers between 1 and 2 ms. Any ideas what else to try would be appreciated, thanks.

• TCP 30 small packets per second flood connection with server

  - by Denis Ermolin

  I'm testing connection with flash client and cloud server(boost::asio for software) over TCP connection. My connection with server already is really poor - 120 ms ping in average. I found when i start to send packets with 2 bytes size (without tcp header) with speed 30 packets/s - ping grow to 170-200 average. I think that it's really bad and my bad connection and bad cloud provider is reason for this high ping without any load. What do you think? (I tested my software - it can compute about 50k small packets/s so software is not a problem). I measure my ping through flash client - send packet with timestamp and immediatly send from server to client.

• How to plot 3D graphs in Excel from CSV data?

  - by Primx

  I have data formatted like this in a csv file: a, 1, 4, 6.0 a, 2, 42, 16.0 a, 5, 14, 69.3 a, 11, 4, 7.0 b, 1, 45, 6.0 b, 2, 45, 1.9 b, 9, 2, 4.4 b, 11, 4, 7.9 lines with first parameter a is one set of data, and first parameter b represents another set. My aim is to plot two lines on the same graph, one with points (1, 4, 6.0), (2, 42, 16.0), (5, 14, 69.3), (11, 4, 7.0) and the other with points (1, 45, 6.0), (2, 45, 1.9), (9, 2, 4.4), (11, 4, 7.9) I am able to import the data directly in MS Excel, but am not sure how to plot them. How can I plot this data?

• static constants return instance of specific class in Flex?

  - by Sang

  So here's what I mean. Let's say I have a class ErrorMessages which holds all my error messages as static constants. So I could access them like ErrorMessages.PASSWORD_INVALID or ErrorMessage.PASSWORD_TOO_SHORT. I want to know if it is possible to have separate classes that hold subset of these constants and access them like ErrorMessages.PASSWORD.INVALID or ErrorMessages.PASSWORD.TOO_SHORT, etc. This way I can more structured static structure and makes it much easier to use autocomplete. I tried few different ways and couldn't figure out if this was possible..

• windows control library in c sharp

  - by apals

  I have just added a textbox, button, label to validate ID of 12 characters. The library is called check_ID. It works fine. The only problem is i have to access the forecolor of label, backcolor of textbox , forecolor of button as per color scheme of the project. But it seems that none of the properties of the objects in check_ID are available for modification. I have even changed the modifier to public of all objects by repoening the check_ID project. Is there another way to access the properties of these objects that are created using windows control library?. A very big thanks in advance.

• Property Scope (Iphone)

  - by Hank

  Hello All. I am having trouble accessing a declared property and I think I am missing something fundamental about the nature of properties and perhaps view controllers. Here's what I'm doing so far: declaring a property "myPhone" in a root view controller called RootViewController. grabbing a phone number from a modally presented people picker setting "myPhone" to the value from the people picker (from within shouldContinueAfterSelectingPerson of ABPeoplePickerNavigationController) trying to access "myPhone" from another modally presented view controller "myPhone" continues to NSLog to null despite trying every permutation of self.myPhone, super, RootViewController, etc. to try and access the value I set. What am I missing?

• Unexpected htaccess behaviour (mod_rewrite and apache)

  - by avastreg

  Yeah, mod_rewrite is driving me crazy. Here is the problem: my htaccess RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ index.php?url=$1 [L,QSA] when i try to access the page advantix (so address was www.mywebsite.com/advantix), i'm being redirected to advantix/?url=advantix Looking at the access log, i have a suspicious 301 in the middle "GET /advantix HTTP/1.1" 301 335 "-" "Mozilla/5.0" "GET /advantix/?url=advantix HTTP/1.1" 200 186 "-" "Mozilla/5.0" There is one important detail: advantix is a directory. So, if i comment that rule, advantix goes to the folder and list the files. Why it applies automatically the / if there's a folder matching? I don't want to reach the folder, i want to reach index.php?url=advantix with a call to advantix. I have the rewriteLogs too, but they didn't help more. My vhost conf has Directory tag with Options All, if helps, i don't know much about that.

• Flag outgoing message for follow-up in Thunderbird

  - by nw

  More and more I need to follow up on specific messages I have sent, but memory fades. Can anyone recommend a way to flag outgoing messages "for follow-up" in Thunderbird? (Not sure but I think MS Outlook supports this.) I have a little hack, which involves a custom rule to tag incoming messages from myself to myself. Then I simply include myself in the recipient list on messages I want to follow up on. But perhaps there is a more elegant extension or technique out there?

• Backdoor Strategy- opinion needed.

  - by the Hampster

  I'm creating an application to track publications and grants for a university. Professors will need to put they CV into the system when it is up and running. Yeah, right. The person in charge is planning on hiring someone to input all of the information, but my questions is how? The strategy I'm thinking of is to install a backdoor. The lucky undergrad can log in as any professor using the backdoor. Once all the data is removed, the backdoor can be removed. Doing so would probably be as simple as editing out a comment in the config file. The IT guys would still have access, but since they control the machines, they would have access anyway. Are there any flaws to this strategy?

• How to scrub a document of all text between brackets with find and replace

  - by sam

  I have a log file and I need to find all instances of <password> hash here </password> and remove the hash and replace it with some dummy text like aaa-aaa-aaa-aaaa. The recurring search argument is anything that matches a bracket that starts with <password> and ends with </password>. All the hashes being replaced will be different. What's the easiest way to go a bout this? The log is on a windows machine. Probably easiest would be to use MS word for me, unless it's achievable with wordpad, notepad, or some other light weight editor like textpad. thanks

• Django ORM dealing with MySQL BIT(1) field

  - by Carles Barrobés

  In a Django application, I'm trying to access an existing MySQL database created with Hibernate (a Java ORM). I reverse engineered the model using: $ manage.py inspectdb > models.py This created a nice models file from the Database and many things were quite fine. But I can't find how to properly access boolean fields, which were mapped by Hibernate as columns of type BIT(1). The inspectdb script by default creates these fields in the model as TextField and adds a comment saying that it couldn't reliably obtain the field type. I changed these to BooleanField but it doesn't work (the model objects always fetch a value of true for these fields). Using IntegerField won't work as well (e.g. in the admin these fields show strange non-ascii characters). Any hints of doing this without changing the database? (I need the existing Hibernate mappings and Java application to still work with the database).

• How to reference a string from another package in a library using XML in Android?

  - by Garret Wilson

  The Android documentation tells me that I can access a string from another package by using the "package name", whatever that means: @[<package_name>:]<resource_type>/<resource_name> So in my manifest I want to access a string that I've placed in a separate library project, in the com.globalmentor.android package---that's where my R class is, after all: <activity android:label="@com.globalmentor.android:string/app_applicationlistactivity_label" android:name="com.globalmentor.android.app.ApplicationListActivity" > </activity> That doesn't even compile. But this does: <activity android:label="@string/app_applicationlistactivity_label" android:name="com.globalmentor.android.app.ApplicationListActivity" > </activity> Why? What does the Android documentation mean which it talks about the "package_name"? Why doesn't the first example work, and why does the second example work? I don't want all my resource names merged into the same R file---I want them partitioned into packages, like I wrote them.

• Is a Multi-DAL Approach the way to go here?

  - by Krisc

  Working on the data access / model layer in this little MVC2 project and trying to think things out to future projects. I have a database with some basic tables and I have classes in the model layer that represent them. I obviously need something to connect the two. The easiest is to provide some sort of 'provider' that can run operations on the database and return objects. But this is for a website that would potentially be used "a lot" (I know, very general) so I want to cache results from the data layer and keep the cache updated as new data is generated. This question deals with how best to approach this problem of dual DALS. One that returns cached data when possible and goes to the data layer when there is a cache miss. But more importantly, how to integrate the core provider (thing that goes into database) with the caching layer so that it too can rely on cached objects rather than creating new ones. Right now I have the following interfaces: IDataProvider is used to reach the database. It doesn't concern itself with the meaning of the objects it produces, but simply the way to produce them. interface IDataProvider{ // Select, Update, Create, et cetera access IEnumerable<Entry> GetEntries(); Entry GetEntryById(int id); } IDataManager is a layer that sits on top of the IDataProvider layer and manages the cache interface IDataManager : IDataProvider{ void ClearCache(); } Note that in practice the IDataManager implementation will have useful helper functions to add objects to their related cache stores. (In the future I may define other functions on the interface) I guess what I am looking for is the best way to approach a loop back from the IDataProvider implementations so that they can access the cache. Or a different approach entirely may be in order? I am not very interested in 3rd party products at the moment as I am interested in the design of these things much more than this specific implementation. Edit: I realize the title may be a bit misleading. I apologize for that... not sure what to call this question.

• Linux cannot see Windows 7 partitions on install

  - by Nash0

  I've been trying to install Linux as a dual boot with Windows 7 on my Dell latitude e6510. It is currently running Windows 7 and I have used the MS disk tools to shrink the Win 7 NTFS partition to make room for Linux. The issue I'm having is that when I run Linux installers by boot from CD they see the entire hard drive as unallocated space. I have tried Ubuntu 10.10, Kbuntu 10.10 and Fedora 14 and they all have the same problem. I have also tried the Ubuntu "install in Windows" option and could not get it to work. EDIT: Booting Gparted 0.8.0 from a usb drive did not work. It reported the entire drive as unpartitioned.
