• PYTHON: ntlm authentication

  - by Svetlana

  Hello!! I'm trying to implement NTLM authentication on IIS (Windows Server 2003) from Windows 7 with python. LAN Manager Authentication Level: Send NTLM response only. Client machine and server are in the same domain. Domain controller (AD) is on another server (also running Windows Server 2003). I recieve 401.1 - Unauthorized: Access is denied due to invalid credentials. Could you please help me find out what is wrong with this code and/or show me the other possible directions to solve this problem (using NTLM or Kerberos)?

• Android layout with 2 evenly spaced Buttons

  - by Rpond

  I have this layout that works correctly, a relative layout with a text view and two buttons spaced evenly below it. <RelativeLayout android:id="@+id/entrypopup" android:layout_width="fill_parent" android:layout_height="wrap_content" android:padding="5px" android:visibility="gone" android:layout_below="@+id/ad" android:background="#80000000"> <TextView android:id="@+id/title" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="Entry Popup..." android:textColor="#ffffffff" android:textSize="20sp" /> <TableLayout android:id="@+id/TableLayout01" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_below="@id/title"> <TableRow android:layout_weight="1"> <Button android:id="@+id/buttonVisit" android:text="View" android:layout_height="fill_parent" android:layout_width="0dip" android:layout_weight="1"/> <Button android:id="@+id/buttonCancel" android:text="Cancel" android:layout_width="0dip" android:layout_weight="1" android:layout_height="fill_parent"/> </TableRow> </TableLayout> </RelativeLayout> But running layoutopt it says that "this TableRow layout or its TableLayout parent is possible useless". Is there a way to do this layout then without the tables?

• IIS 7.5, ASP.NET, impersonation, and access to C:\Windows\Temp

  - by Heinzi

  Summary: One of our web applications requires write access to C:\Windows\Temp. However, no matter how much I weaken the NTFS permission, procmon shows ACCESS DENIED. Background (which might or might not be relevant for the problem): We are using OLEDB to access an MS Access database (which is located outside of C:\Windows\Temp). Unfortunately, this OLEDB driver requires write access to the user profile's TEMP directory (which happens to be C:\Windows\Temp when running under IIS 7.5), otherwise the dreaded "Unspecified Error" OleDbException is thrown. See KB 926939 for details. I followed the steps in the KB article, but it doesn't help. Details: This is the output of icacls C:\Windows\Temp. For debugging purposes I gave full permissions to Everyone. C:\Windows\Temp NT AUTHORITY\SYSTEM:(OI)(CI)(F) CREATOR OWNER:(OI)(CI)(IO)(F) BUILTIN\IIS_IUSRS:(OI)(CI)(S,RD) BUILTIN\Users:(CI)(S,WD,AD,X) BUILTIN\Administrators:(OI)(CI)(F) Everyone:(OI)(CI)(F) However, this is the screenshot of procmon: Desired Access: Generic Read/Write, Delete Disposition: Create Options: Synchronous IO Non-Alert, Non-Directory File, Random Access, Delete On Close, Open No Recall Attributes: NT ShareMode: None AllocationSize: 0 Impersonating: MYDOMAIN\myuser

• Permission denied: .hg\store\lock

  - by harpo

  This smells like a serverfault question, yet there are many similar questions here. Your call. I'm setting up Mercurial over IIS6, and thanks to a number of detailed blogs, it's working fine — almost. I can browse and clone the repositories fine, but this is what happens when I try to push: D:\sample2>hg push pushing to http://localhost/hg/sample2 searching for changes abort: HTTP Error 500: Permission denied: .hg\store\lock First of all, there is no such file or folder. Second, the App Pool's logon has total permission on the repository's parent directory, with these inherited ad infinitum. The repository is located on another logical drive (on the same machine), and if I push to it directly, that also works: D:\sample2>hg push e:\hg\sample2 pushing to e:\hg\sample2 searching for changes adding changesets adding manifests adding file changes added 1 changesets with 1 changes to 1 files If I change the password in my hgrc, the message indicates a failed authorization, so I believe that's working. I've been fighting this for a couple of days, so any leads would be helpful. Thanks!

• Confusion about Kerberos, delegation and SPNs.

  - by Vilx-

  I'm trying to write a proof-of-concept application that performs Kerberos delegation. I've written all the code, and it seems to working (I'm authenticating fine), but the resulting security context doesn't have the ISC_REQ_DELEGATE flag set. So I'm thinking that maybe one of the endpoints (client or server) is forbidden to delegate. However I'm not authenticating against an SPN. Just one domain user against another domain user. As the SPN for InitializeSecurityContext() I'm passing "[email protected]" (which is the user account under which the server application is running). As I understand, domain users have delegation enabled by default. Anyway, I asked the admin to check, and the "account is sensitive and cannot be delegated" checkbox is off. I know that if my server was running as a NETWORK SERVICE and I used an SPN to connect to it, then I'd need the computer account in AD to have the "Trust computer for delegation" checkbox checked (off by default), but... this is not the case, right? Or is it? Also - when the checkbox in the computer account is set, do the changes take place immediately, or must I reboot the server PC or wait for a while?

• Development process for an embedded project with significant hardware changes

  - by pierr

  I have a good idea about Agile development process but it seems it does not fit well with a embedded project with significant hardware changes. I will describe below what we are currently doing (Ad-hoc way, no defined process yet). The changes are divided into three categories and different processes are used for each of them: complete hardware change example : use a different video codec IP a) Study the new IP b) RTL/FPGA simulation c) Implement the legacy interface - go to b) d) Wait until hardware (tape out) is ready f) Test on the real hardware hardware improvement example : enhance the image display quality by improving the underlying algorithm a) RTL/FPGA simulation b) Wait until hardware and test on the hardware Minor change example : only change hardware register mapping a) Wait until hardware and test on the hardware The worry is it seems we don't have too much control and confidence about software maturity for the hardware changes as the bring-up schedule is always very tight and the customer desired a seamless change when updating to a new version of hardware. How did you manage this kind of hardware change? Did you solve that by a Hardware Abstraction Layer (HAL)? Did you have a automatic test for the HAL layer? How did you test when the hardware platform is not even ready? Do you have well-documented processes for this kind of change?

• Code Golf: 1x1 black pixel

  - by Joey Adams

  Recently, I used my favorite image editor to make a 1x1 black pixel (which can come in handy when you want to draw solid boxes in HTML cheaply). Even though I made it a monochrome PNG, it came out to be 120 bytes! I mean, that's kind of steep. 120 bytes. For one pixel. I then converted it to a GIF, which dropped the size down to 43 bytes. Much better, but still... Challenge The shortest image file or program that is or generates a 1x1 black pixel. A submission may be: An image file that represents a 1x1 black pixel. The format chosen must be able to represent larger images than 1x1, and cannot be ad-hoc (that is, it can't be an image format you just made up for code golf). Image files will be ranked by byte count. A program that generates such an image file. Programs will be ranked by character count, as usual in code golf. As long as an answer falls into one of these two categories, anything is fair game.

• Is it possible to seletively color a wrapping TextBlock in Silverlight/WPF

  - by joemoe

  For instance, if I have a TextBlock: "Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum." I want the first 10% of this TextBlock, such that the font color should be red, and the rest should be green. This perhaps means it would color the "Lorem ipsum dolor sit amet, consectetur adipisici", and part of the "n". Basically pixel-wise font coloring instead of character-wise. Another important behavior is that the percentage respects the wrapping, in that if 50% of the TextBlock contents is colored, it should mean 50% of the text in reading order is colored, and not the first half of the block. For example, this is a similar question (with correct answers), but regarding Label/TextBlocks with no wrapping: http://stackoverflow.com/questions/2394421/is-it-possible-to-seletively-color-a-label-in-silverlight

• Dynamics CRM Customer Portal Accelerator Installation

  - by saturdayplace

  (I've posted this question on the codeplex forums too, but have yet to get a response) I've got an on-premise installation of CRM and I'm trying to hook the portal to it. My connection string in web.config: <connectionStrings> <add name="Xrm" connectionString="Authentication Type=AD; Server=http://myserver:myport/MyOrgName; User ID=mydomain\crmwebuser; Password=thepassword" /> </connectionStrings> And my membership provider: <membership defaultProvider="CustomCRMProvider"> <providers> <add connectionStringName="Xrm" applicationName="/" enablePasswordRetrieval="false" enablePasswordReset="true" requiresQuestionAndAnswer="false" requiresUniqueEmail="true" passwordFormat="Hashed" minRequiredPasswordLength="1" minRequiredNonalphanumericCharacters="0" name="CustomCRMProvider" type="System.Web.Security.SqlMembershipProvider" /> </providers> </membership> Now, I'm super new to MS style web development, so please help me if I'm missing something. In Visual Studio 2010, when I go to Project ASP.NET Configuration it launches the Web Site Administration Tool. When I click the Security Tab there, I get the following error: There is a problem with your selected data store. This can be caused by an invalid server name or credentials, or by insufficient permission. It can also be caused by the role manager feature not being enabled. Click the button below to be redirected to a page where you can choose a new data store. The following message may help in diagnosing the problem: An error occurred while attempting to initialize a System.Data.SqlClient.SqlConnection object. The value that was provided for the connection string may be wrong, or it may contain an invalid syntax. Parameter name: connectionString I can't see what I'm doing wrong here. Does the user mydomain\crmwebuser need certain permissions in the SQL database, or somewhere else? edit: On the home page of the Web Site Administration Tool, I have the following: **Application**:/ **Current User Name**:MACHINENAME\USERACCOUNT Which is obviously a different set of credentials than mydomain\crmwebuser. Is this part of the problem?

• Issues Connecting to SQLExpress using Oracle SQL Developer

  - by ArtDeveloper

  Hey Guys, I'm trying to create a connection inside Oracle SQL Developer to a SQLExpress database I have Everything I have resides on the same machine so there isn't any network issues I should have to deal with but everytime I follow the instructions and I try to connect I get the following message "Failure - Unable to get information from SQL Server: localhost." I can connect to the SQLExpress DB using the SQL Management Studio and through an ODBC connection. I've installed the third party extensions and I've enabled the TCP protocol on the SQL Server Configuration manager as well as enabled the IP Addresses I'm assuming that the SQLExpress Database is on port 1433 because I didn't change this when I installed but if someone can tell me how to double check that I would appreciate that info as well. I setup the new connection with the following information name: databasename I'm using windows authentication so the username and password aren't filled in host:localhost port:1433/databasename;instance=SQLEXPRESS *databasename - this is replaced with the actual DB name I've just changed the name here to protect the innocent I've spent about a full day on this trying to get it connected and many google attempts where other ppl have had this issue but have gotten it solved through various methods that I've tried and it hasn't resolved my issue. Any information would be much appreciated Thank you in Advance, AD

• Difference between JodaTime and Calendar for years before 1900

  - by Yury Khrol

  I'm getting different values in milliseconds for the same date in past while using JodaTime lib and java.util.Calendar. For example for the first year AD void test() { int year = 1; DateTime dt = new DateTime(year, 1,1,0,0,0,0); dt = dt.toDateTime(GregorianChronology.getInstance()); Calendar cal = Calendar.getInstance(); cal.clear(); cal.set(year, 0, 1, 0, 0, 0); DateTime endDate = new DateTime(cal.getTimeInMillis()); endDate = endDate.toDateTime(GregorianChronology.getInstance()); System.out.println("JodaTime: " + dt); System.out.println("JodaTime, ms: " + dt.getMillis()); System.out.println("Calendar: " + cal.getTime()); System.out.println("Calendar, ms: " + cal.getTimeInMillis()); System.out.println("JodaTime by Calendar: " + endDate); } By default DateTime use ISOChronology and Calendar is GregorianCalendar (except TH and JA locales). So I set GregorianChronology, but nothing changed. Result of execution is JodaTime: 0001-01-01T00:00:00.000+01:34:52 JodaTime, ms: -62135602492000 Calendar: Sat Jan 01 00:00:00 EET 1 Calendar, ms: -62135776800000 JodaTime by Calendar: 0000-12-29T23:34:52.000+01:34:52 Could someone suggest am I wrong with something?

• Trying to Create an Enterprise Provisioning Profile--Distribution Tab is Missing

  - by El' Jocko

  I'm attempting to create an Enterprise Provisioning Profile, but the program portal isn't working the way I expect it to (based on the documentation). Here's what I'm seeing: First, I log on as the Team Agent. Second, I navigate to the Provisioning section of the program portal. According to the documentation, I should see 4 tabs at this point: Development, Distribution, History, How To. But when I do this, the Distribution tab isn't there. And without the Distribution tab, I can't create a Enterprise Provisioning Profile (or an Ad Hoc one, for that matter). I've tried contacting Apple administrative support, but they weren't able to provide any help with this. They suggested that I try the forum. :-) Just to fill in a few more details: My company has an enterprise membership in the developer program. And when I navigate to the Certificates section, there is a Distribution tab. I figure that there must be something that I've done incorrectly. Has anyone had a similar experience? Any suggestions on what to try next?

• Need help unformatting text

  - by Axilus

  I am currently programming a Visual C# service to receive emails from various sources then I take certain info and organize it in a database using Regex to retrieve the deferent cell values (such as header, body, problem, cost, etc.etc.). My problem is that I am currently using a Hotmail account to email the service which the service then extracts data and writes it to a csv file; however this is all going fine an dandy except for the fact that the text is formated so when there is a "\n" or something of the sort, the program decides to not input the data that follows that into the cell. For instance, if I emailed this: Cost:$1000.00 Body: Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed vulputate mattis dolor, a dapibus turpis lacinia mollis.

• How to change the Struts2 validation error message in the case of an invalid field value?

  - by FarmBoy

  I'm using Struts2 validation on a web form. In the case that a field is suppose to be an integer or Date, the <s:fielderror> message I receive is a generic Invalid field value for field "[fieldname]" Naturally, I want to customize this for the user. Here's an example validation: <field name="spouseDOB"> <field-validator type="date"> <message>"Spouse Date of Birth" is invalid.</message> </field-validator> <field-validator type="date"> <param name="min">01/01/1900</param> <message>"Spouse Date of Birth" must be after 1900 AD. </field-validator> </field> The message "Spouse Date of Birth" is invalid. never appears, for any invalid date that I have tried. The output is the generic Invalid field value for field spouseDOB spouseDOB is a java.util.Date object in the action class. It is set by a <s:textfield> in the JSP.

• OLAP Web Visualization and Reporting Recommendations

  - by Gok Demir

  I am preparing an offer for a customer. They proide weekly data to different organizations. There is huge amount data suits OLAP that needed to be visualized with charts and pivot tables on web and custom reports will be built by non-it persons (an easy gui). They will enter a date range, location which data columns to be included and generate report and optionally export the data to Excel. They currently prepare reports with MS Excel with Pivot Tables and but they need a better online tool now to show data to their customers. Tables are huge and need of drill-down functionality. My current knowledge Spring, Flex, MySql, Linux. I have some knowledge of PostgreSQL and MSSQL and Windows. What is the easiest way of doing this project. Do you think that SSRP (haven't tried yet) and ASP.NET better suits for this kind of job. Actually I prefer open source solutions. Flex have OLAP Data Grid control which do aggregation on client side. JasperServer seems promising but it seems I need enterprise version (multiple organizations and ad hoc queries). What about Modrian + Flex + PostgreSQL solution? Any previous experience will be appreciated. Yes I am confused with options.

• How to group strings by prefix

  - by namenlos

  I am writing a Winform UI in which the user must select a single customer. (For reasons beyond my control I am limited to a UI that uses dropdown lists, text fields, checkboxes, radiobuttons only -i.e. no fancy special UI controls) The situation There are a lot of customers (a thousand for example) If i put all the customers in a single dropdown there's no way it will be easy for a customer to even see all the customers. Also the it will take too long to retireve all the customers from the DB to populate the dropdown My thought is to have two combo box, the first lists groups of the customers by their last name something like a phone book "Aa-Ac", "Ad-Ade", "Adf-B", when selecting the first combo box, it scope the second one to a managable set customer names (no more than for example 40 names) The question I need a reasonable way of grouping their names such that it will be clear to customer which group contains the name. I.e. given a group of names I need to bucketize then int "Aa-Ac". Comments I don't need to solve the general problem of an immense number of names - we know based on our data that 1000 names is the max our users will encounter. If there are other techniques please do share, but I am interested specifically in an answer to my specific question around how to determine the buckets ("Aa-Ac", etc.)

• Silverlight performance with a large number of Objects Org Chart.

  - by KC

  Hello, I’m working on a org chart project(SL 3) and I’m seeing the UI thread hang when the chart is building around 2,000 nodes and when it renders it takes about a min and then FPS drop to a crawl. Here is the code flow. Page.xaml.cs calls a wcf service that returns a list of AD users. Then we use Linq to build a collection of nodes to bind to the Orgchart.cs OrgChart.cs is a canvas and displays a collection of nodes and connecting lines. Node.cs is a canvas and has user data can contain children nodes. NodeContent.xaml is a user control that has borders so I can set the background, textblocks to display user's data, Events that handle the selected and expaned nodes, and storyboards that resize the nodes when they are selected or expanded.I noticed during hours of debugging , here in the InitializeComponent(); section where it loads the xaml it seems to be where the preformance hit is happening. System.Windows.Application.LoadComponent(this, new System.Uri("/Silverlight.Custom;component/NodeContent.xaml", System.UriKind.Relative)); So I guess I have two questions. Can threading help in any way with the UI thread hanging while drawing the nodes? How can I avoid the hit when calling this user control? Any advice or direction anyone can lend would be greatly appreciated. Thanks, KC

• Dynamic where clause using Linq to SQL in a join query in a MVC application

  - by jhoefnagels

  Dear .Net Linq experts, I am looking for a way to query for products in a catalog using filters on properties which have been assigned to the product based on the category to which the product belongs. So I have the following entities involved: Products -Id -CategoryId Categories [Id] Properties [Id, CategoryId] PropertyValues [Id, PropertyId] ProductProperties [ProductId, PropertyValueId] When I ad a product to the catalog, multiple ProductProperties will be added based on the category and I would like to be able to filter all products from a category by selecting values for one or more properties. I will gather all filters, which I will hold in a list, by reading the URL. Now it is time to actually get the products based on multiple properties and I have been trying to find the right strategy but untill now it does not really work. Is there a way to make this work without writing SQL? I was trying something like this: productsInCategory = ProductRepository.Where(p => p.Category.Name == category); foreach (PropertyFilter pf in filterList) { productsInCategory = (from product in productsInCategory join pp in ProductPropertyRepository on product.Id equals pp.ProductId where pp.PropertyValueId == pf.ValueId select product); }

• How to show AdMob ads in real iPhone device?

  - by iPhoney

  I want to integrate AdMob ads in my iPhone app. I'm using IB way to add the view and follow AdMob's pdf guide: 1. Add AdMob group(AdMobView.h,AdMobDelegateProtocol.h,libAdMob.a) 2. Add required frameworks(AudioToolbox,MediaPlayer,MessageUI,QuartzCore) 3. Add TouchJSON group 4. Add IBSupport group(AdViewController.h,AdViewController.m) 5. Add a 320*48 UIView in IB, add NSObject and change its class to AdViewController, link AdViewController's view to the 320*48 UIView and link AdViewController's viewController to current view controller. Now the iPhone simulator can show ads from AdMob, but when I test it on real device, I get the error "AdMob: Did fail to receive ad". I've tried to add test device's UDID to testDevices array, but still get the same error. - (NSArray *)testDevices { return [NSArray arrayWithObjects: ADMOB_SIMULATOR_ID, DEVICE_UDID, nil]; } Is there any problem in the above steps? Does anybody know why can't I get the ads in real device? By the way, what should be changed to build for real for-sale app, not just for test?

• Why won't .attr('checked','checked') set?

  - by Jason

  I have the following snippet of code (I'm using jQuery 1.4.2): $.post('/Ads/GetAdStatsRow/', { 'ad_id': id }, function(result) { $('#edit_ads_form tbody').prepend(result); $(result).find('td.select-ad input').attr('checked','checked').click(); }); Assume that the post works correctly and returns a correct pre-built <tr> with some <td>s. Here's the weirdness: the $(result).find() line finds the correct input (which is a checkbox, as it's the only input in the cell) and runs the chained click() function correctly, but it REFUSES to set the box as checked, which I need to happen. Here's a crazy twist, too... when I get super specific and change the $(result).find() line to this (the id of the checkbox): $('#ad_' + id).click(); It checks the box, but doesn't run the click() function! If I set it to $('#ad_' + id).attr('checked','checked').click(); it runs the click function as though the box were checked, but the box remains unchecked, and if I do $('#ad_' + id).click().attr('checked','checked'); it does nothing at all. What in the world could be the matter with this? I'm running out of hair.... Thanks!

• Symfony/Propel NestedSet left/right ID corruption/adjustment

  - by Mike Crowe

  Hi folks, I have a nested set application that seems to be getting corrupted. Here's what I'm seeing: We're using nested sets for a binary tree (any node can have 2 children). It appears to be working fine, but some event causes a discrepancy. For instance, when I do a getNumberOfDescendants() for the root node, it will slowly increase as this event happens. However, displaying the tree works fine, as does inserting (apparently). Has anybody seen anything like this before? For instance, my repair program shows this as the repairs that it makes: User pxxxxx left 0=>0, right 145=>129 User axxxxx left 1=>1, right 124=>106 User mxxxxx left 119=>117, right 120=>118 User fxxxxx left 125=>107, right 144=>128 User fxxxxx left 126=>108, right 131=>113 User rxxxxx left 127=>109, right 128=>110 User mxxxxx left 129=>111, right 130=>112 User mxxxxx left 132=>114, right 143=>127 User cxxxxx left 133=>115, right 142=>126 User gxxxxx left 134=>116, right 137=>121 User mxxxxx left 135=>119, right 136=>120 User jxxxxx left 138=>122, right 141=>125 User axxxxx left 139=>123, right 140=>124 I thought at first it was when I deleted a user, but it has since occurred w/o that event. Anybody know of a cause that might generate this? I've tested ad nauseum on my local machine, but I can't duplicate it. I do have an issue where my production box is PHP 5.2.0, whereas my test device is 5.2.10. Could that be an issue? TIA Mike

• choosing row (from group) with max value in a SQL Server Database

  - by sriehl

  I have a large database and am putting together a report of the data. I have aggregated and summed the data from many tables to get two tables that look like the following. id | code | value id | code | value 13 | AA | 0.5 13 | AC | 2.0 13 | AB | 1.0 14 | AB | 1.5 14 | AA | 2.0 13 | AA | 0.5 15 | AB | 0.5 15 | AB | 3.0 15 | AD | 1.5 15 | AA | 1.0 I need to get a list of id's, with the code (sumed from both tables) with the largest value. 13 | AC 14 | AA 15 | AB There are 4-6 thousand records and it is not possible to change the original tables. I'm not too worried about performance as I only need to run it a few times a year. edit: Let me see if I can explain a bit more clearly, imagine the id is the customer id, the code is who they ordered from and the value is how much they spent there. I need a list of the all the customer id's and the store that customer spent the most money at (and if they spent the same at two different stores, put a value such as 'ZZ' in for the store name).

• ForeignSecurityPrincipals with LDAP connection on Active Directory servers with trusted forest

  - by Killerwhile

  The context is the following : Two domains mutually trusted dc=dom1 dc=dom2 a group cn=group1,ou=someou,dc=dom1 with users inside : cn=user11,ou=anotherou,dc=dom1 cn=user12,ou=anotherou,dc=dom1 cn=user13,ou=anotherou,dc=dom1 cn=user21,ou=anotherou,dc=dom2 cn=user22,ou=anotherou,dc=dom2 cn=user23,ou=anotherou,dc=dom2 The questions : 1. Test user's credentials How can I do a ldap bind to test credentials for users of dom2 ? I tried to bind as usual but I cannot authenticate users of dom2, even if I connect in ldaps. Is there any trick ? Special permissions to set ? 2. Search and display users from the group. How can I retrieve the detailed informations about the users of dom1 and dom2 using LDAP(s) connection on the AD of dom1 ? I have an technical user which has right to browse both domain. I'm able to see 6 entries in the group with the following filter : (&(memberOf=cn=group1,ou=someou,dc=dom1)(|(objectClass=user)(objectClass=foreignSecurityPrincipal))) but the users from the other domain are seen as cn=...(some key)...,cn=foreignSecurityPrincipal,dc=dom1 Java hints would be better. Thanks a lot !

• Developmnet process for an embedded project with significant Hardware change

  - by pierr

  Hi, I have a good idea about Agile development process but it seems it does not fit well with a embedded project with significant hardware change. I will describe below what we are currently doing (Ad-hoc way , no defined process yet). The change are divided to three categories and different process are used for them : complete hardware change example : use a different video codec IP a) Study the new IP b) RTL/FPGA simulation c) Implement the leagcy interface - go to b) d) Wait until hardware (tape out) is ready f) Test on the real Hardware hardware improvement example : enhance the image display quaulity by improving the underlie algorithm a)RTL/FPGA simulation b)Wait until hardware and test on the hardware Mino change exmaple : only change hardware register mapping a)Wait until hardware and test on the hardware The worry is it seems we don't have too much control and confidence about software maturity for the hardware change as the bring up schedule is always very tight and the customer desired a seemless change when updating to a new version hardware. How did you manage this kind of hardware hardware change? Did you solve that by a Hardware Abstraction Layer (HAL)? Did you have a automatical test for the HAL layer? How did you test when the hardware platform is not even ready? Do you have well documented process for this kind of change? Thanks for your insight.

• Create Keyword Object Perl Microsoft::AdCenter

  - by toobsco42

  So I looked at the perldoc for the Microsoft::AdCenter module and it shows this as an example of how to create a keyword object: ~$ perldoc Microsoft::AdCenter #Create a Keyword object my $keyword = Microsoft::AdCenter::V7::CampaignManagementService::Keyword->new ->Text("some text") ->BroadMatchBid(Microsoft::AdCenter::V7::CampaignManagementService::Bid->new->Amount(0.1)) ->ExactMatchBid(Microsoft::AdCenter::V7::CampaignManagementService::Bid->new->Amount(0.1)); However, doesn't this violate the new policy of using only one match type per keyword? Campaign Management changes: "Previously, you would create a single Keyword object and specify a bid value for each match that you wanted to bid on (for example, exact match or phrase match). If you did not specify a bid value at the keyword-level, adCenter used the default bid value specified at the ad group level. Now, you must create a Keyword object for each match type that you want to bid on. For example, to bid on the keyword car by using exact match and phrase match, create a Keyword object and set the Text element to car and the ExactMatchBid element to a bid amount. Then, create a second Keyword object and set the Text element to car and PhraseMatchBid to a bid amount. When you add the keywords, you’ll get a unique keyword ID for each keyword and match-type combination."
