• More Mobile Payments

  - by David Dorf

  In the previous post I discussed the Bump Payments from PayPayl, but that's not the only innovative way to make purchases using your phone. Verizon recently announced a partnership with Danal that allows shoppers to charge online purchases to their Verizon bill. For e-commerce sites that accept this type of payment, it's a two step process. At checkout, the shopper enters their mobile number and billing zip code. Then a SMS message is sent to the mobile phone that contains a one-time code that must be entered on the e-commerce site. This two-factor authentication seems pretty secure, and no pre-registration or credit card is necessary. There's a $25 a month maximum, but I bet the limit gets raised as Verizon gets more comfortable with security. Merchants are charged a fee similar to credit card fees. Another example of mobile payments is offered by BlingNation. Customers attach a small NFC sticker to their phones that allows them to "tap" the POS device to make a payment. The NFC chip is connected to their checking account, so the transaction is treated as a debit payment. Text messages are sent to the mobile that confirm the payments so shoppers can easily verify their purchases. BlingNation is working with banks like Adirondack Trust Company and The State Bank of La Junta in Colorado. Heck, you can even send money to inmates in the Arkansas prison system using your mobile phone now that the state of Arkansas supports payments via their mobile website. Everyone is getting into the act now.

• SOA Suite Integration: Part 2: A basic BPEL process

  - by Anthony Shorten

  This is the next in the series about SOA Suite integration with Oracle Utilities Application Framework. One of the first scenarios I am going to illustrate in this series is building a basic BPEL process using Web Service calls to the Oracle Utilities Application Framework. The scenario is this. I will pass in the userid and the BPEL process will call our the AS-User Web Service we created in Part 1. This is just a basic test and illustrate how to import the Web Service into SOA Suite. To use this scenario, you will need access to Oracle SOA Suite, access to a copy of any Oracle Utilities Application Framework based product and Oracle JDeveloper (to build the process). First of all you need to start Oracle JDeveloper and create a new SOA Project to house the BPEL process in. For the purposes of this example I will call the project simpleBPEL and verify that SOA is part of the project. I will select "Composite with BPEL" to denote it as a BPEL process. I can also the same process to create a Mediator or OSB project (refer to the JDeveloper documentation on these technologies). For this example I will use BPEL 1.1 as my specification standard (BPEL 2.0 can also be used if desired). I give the individual BPEL process as simpleBPEL (you can use a different name but I wanted to keep the project and process the same for this example). I will also build a Synchronous BPEL Process as I want a response from the Web Service. I will leave the defaults to save time. I have no have a blank canvas to build my BPEL process against. Note: for simplicity I am going to use as much defaulting as possible. In fact I am not going to specify an input schema for the incoming call as I will use the basic single field used by BPEL as default. The first step is to import the AS-User Web Service into my BPEL project. To do this I use the standard Web Service BPEL component from the Component Palette to import the WSDL into the BPEL project. Now the tricky part (a joke), you drag and drop the component from the Palette onto the right side of the canvas in the Partner Links swim lane. This swim lane is reserved for Partner Links that have a Partner Role (i.e. being called rather than calling). When you drop the Web Service onto the canvas the Create Web Service wizard is invoked to ask for details of the Web Service. At this point you give the BPEL node a name. I have used the name RetrieveUser as a name. I placed the WSDL URL from the XAI Inbound Service screen in the WSDL URL. Once you specify the URL you can press the Find existing WSDL's button to load the information into BPEL from the call. You will notice the Port Type is prefilled with the port from the WSDL. I also suggest that you check copy wsdl and it's dependent artifacts into the project if you intending to work on the BPEL process offline. If you do not check this your target application must be accessible when you work on the BPEL process (that is not always convenient). Note: For the perceptive of you will notice that the URL specified in this example is different to the URL in the last post. The reason is for the demonstrations I shifted to a new server and did not redo all of the past screen captures. If you copy the WSDL into the project you will get an information screen about Localize Files. It is just a confirmation screen. The last confirmation screen is a summary of the partner link (the main tab is locked for editing at this stage). At this stage you have successfully imported the Web Service. To complete the setup of the Web Service you need to set the credentials for the Web Service to use. Refer to the past post on how to do that. Now to use the Web Service. To call the Web Service (as it is just imported not connected to the BPEL process yet), you must add an Invoke action to your BPEL Process. To do this, select Invoke action from the BPEL Constructs zone on the Component Palette and drop it on the edit nodes between the receiveInput and replyOutput nodes This will create an empty Invoke action. You will notice some connectors on the Invoke node. Grab the node closest to your Web Service and drag it to connect the Invoke to your Web Service. This instructs BPEL to use the Invoke to call the Web Service. Once the Invoke action is connected to the Web Service an Edit Invoke edit dialog is displayed. At this point I suggest you name the Invoke node. It is important to name the nodes straightaway and name them appropriately for you to trace the logic. I used InvokeUser as the name in this example. To complete the node configuration you must create Variables to hold the input and output for the call. To do this clock on Automatically Create Input Variable on the Edit Invoke dialog. You will be presented with a default variable name. It uses the node name (that is why it is important to name the node before hitting this button) as a prefix. You can name the variable anything but I usually take the default. Repeat the same for the output variable. You now have a completed node for invoking the service. You have a very basic BPEL process which contains an input, invoke and output node. It is not complete yet though. You need to tell the BPEL process how to pass data from the input to the invoke step and how to take the output from the service call and pass it back to the service. You need to now add an Assign node to assign the input to the Web Service. To do this select Assign activity from BPEL Constructs zone in the Component Palette. Drag and drop the Assign activity between the receiveInput and InvokeUser nodes as you want to pass data between these two nodes. You have now added a new Assign node to your BPEL process Double clicking the node allows you to specify the name of the node. I use AssignUser to describe that I am assigning user data. On the Copy Rules tab you can specify the mapping between the input variable InputVariable/payload/process/input string and the input variable for the Web Service call. We are passing data from the input to BPEL to the relevant input variable on the Web Service. This is simply drag and drop between the two data structures. In the example, I am using the input to pass to the user element in my Web Service as the user is the primary key for the object. The fields become linked (which means data from source will be copied to target). Almost there. You now need to process the output from the Web Service call to the outputVariable of the client call. I have decided to pass back one piece of data, the name associated with the user by concatenating the firstName and lastName elements from the Web Service call. To do this I will use a Transform as it is not just a matter of an Assign action. It is a concatenation operation. This also illustrates how you can use BPEL functionality to transform data from a Web Service call. As with the other components you drag and drop the Transform component to the appropriate place in the BPEL process. In this case we want to transform the output from the Web Service call so we want it after the InvokeUser action and the replyOutput action. The Transform component is actually part of the Oracle Extensions to the BPEL specification. Double clicking the Transform node will allow you to name the node.  In this example I used TransformName. To complete the transform I need to tell the product the source of the transformation and the target of the transform. In the example this is the InvokeUser output variable. I also named the mapper file to TransformName. By clicking the + or pencil icon next to the map I can create the map. The mapping screen is shows the source and target schemas for me to map across. As with the assign I can map the relevant elements. In my example, I first map the firstName from the Web Service to the result element. As I want to concatenate the names, I drop the concat function on the call line. I now attach the last name to the function to indicate the concatenation of the field. By default the names will be concatenated with no space. To make the name legible I add a space between the field by clicking the function and adding a space in the call. I now have a completed mapping. I can now save the whole project as my BPEL process is now complete. As you can see the following happens: We accept input from the client (the userid for the call) in the receiveInput step. We assign that value to the input parameters for the Web Service call in the AssignUser step. We invoke the Web Service call to retrieve the data from the product in the InvokeUser step. We take the output from the InvokeUser step and concatenate the names in the TransformName step. We pass back the data in the replyOutput step. At this point we can deploy the BPEL process to the SOA Suite server. I will not cover this aspect as it really all SOA Suite specific (it is all done via Oracle JDeveloper). Now we need to test the service in SOA Suite. We will use the Fusion Middleware Control test facility. I will assume that credentials have also been setup as per our previous post (else you will get a 401 error). You navigate to the deployed BPEL process within Fusion Middleware Control and select the Test Service option. Specify some test data on the payload at the bottom of the Test Service screen. In my case I am returning my own userid information. On the response tab you will see the result. It works. You can verify the steps using the Audit trace facility on individual calls. As you can see this is a basic BPEL but you get the idea of importing the Web Service is pretty straightforward. You can create more sophisticated BPEL processes using the full facilities in Oracle SOA Suite. I just showed you the basic principals.

• Are `break` and `continue` bad programming practices?

  - by Mikhail

  My boss keeps mentioning nonchalantly that bad programmers use break and continue in loops. I use them all the time because they make sense; let me show you the inspiration: function verify(object) { if (object->value < 0) return false; if (object->value > object->max_value) return false; if (object->name == "") return false; ... } The point here is that first the function checks that the conditions are correct, then executes the actual functionality. IMO same applies with loops: while (primary_condition) { if (loop_count > 1000) break; if (time_exect > 3600) break; if (this->data == "undefined") continue; if (this->skip == true) continue; ... } I think this makes it easier to read & debug; but I also don't see a downside. Please comment.

• Workshop in Holland - and open questions

  - by Mike Dietrich

  Thanks to everybody visiting yesterday the Upgrade Workshop in Maarsen. I had lots of fun - and I hope you'd enjoy it, too :-) The slides, as always, can be downloaded from: http://apex.oracle.com/folien Use the Schluesselwort/Keyword: upgrade112 And thanks to all those of you sending feedback regarding "traget/destination" (will change it in the slides) and other topics such as Enterprise Manager Grid Control 11g. Enterprise Manager 11g will be launched on 22-APR-2010 - and you can join the event live if you will be accidentialy in New York:http://www.oracle.com/enterprisemanager11g/index.html Thanks for this hint!!! Regarding the open questions: Will there be PSUs available for Intel Solaris? PSUs will be made available on nearly all platforms including Intel Solaris. Please see Note:882604.1 for platform information and Note:854428.1 for direct links to the PSU download location. Is COMMIT_WRITE=NOWAIT the default in patch set 10.2.0.4? I tried to verify this and neither couldn't find a bug entry nor a documentation saying the 10.2.0.4 has a different default setting (default behaviour is WAIT). Checked it in my 10.2.0.4 instances as well and there it is set to WAIT. If this parameter is not explicitly specified, then database commit behavior defaults to writing commit records to disk before control is returned to the client. If only IMMEDIATE or BATCH is specified, but not WAIT or NOWAIT, then WAIT mode is assumed. If only WAIT or NOWAIT is specified, but not IMMEDIATE or BATCH, then IMMEDIATE mode is assumed Please feedback to me if you have different experiences. Service Request escalation by telephone? Thanks for this update - I didn't realize that ;-) Now I know why it hasn't helped last month when I've updated an SR ... here's the official information on that: Note:199389.1 - Note has been updated on 24-FEB-2010. See the telephone number to Oracle support to request an escalation here: http://www.oracle.com/support/contact.html

• Weird entry for robots.txt on a Naked Domain in Google Webmaster Tools

  - by Metalshark

  We own a .co.uk address and use an Internet hosting company that has made mistakes around DNS in the past. Our main site is hosted on www. and their reluctance to allow editing of AAAA records on-line means our naked domain does not resolve. Currently when we attempt to reach the naked version there is no entry for the browser to go to and it displays an unreachable page (nslookup just says Name: name of domain with no further entries such as an IP or Canonical Name). We recently added the relevant TXT records to verify us to view both the www. version and the naked version of the domain in Google Webmaster Tools (in anticipation of the requests to our Internet host coming to fruition). Imagine our shock when double checking the Site configuration Crawler access and finding a (admittedly failing) robots.txt with a dynamically generated HTML page (full of crude pop-up JavaScript) with references to 3 of our most prominent competitors. What could cause this to happen? As we are in the UK I am assuming some DNS server is serving Google bad information. We are going to contact the Internet hosting company to fix our A and AAAA records once and for all, then check that they work in the US (using something like OpenDNS). Should we be doing more though, for instance informing Google (through Webmaster Tools) that we are now aware there is something currently wrong with our naked domain? UPDATE: We have fixed our A records (not AAAA) and that has resolved the issue. But if there are further actions we should take for effectively having a parking page hosted on our active visitor-heavy, SEO-rich domain that advertised our competitors to US visitors, what would they be?

• Growing Into Enterprise Architecture

  - by pat.shepherd

  I am writing this post as I am in an Enterprise Architecture class, specifically on the Oracle Enterprise Architecture Framework (OEAF).  I have been a long believer that SOA’s key strength is that it is the first IT approach that blends or unifies business and technology.  That is a common view and is certainly valid but is not completely true (or at least accurate).  As my personal view of EA is growing, I realize more than ever that doing EA is FAR MORE than creating a reference architecture, creating a physical architecture or picking a technology to standardize on.  Those are parts of the puzzle but not the whole puzzle by any stretch. I am now a firm believer that the various EA frameworks out there provide the rigor and structure required to allow the bridging of business strategy / vision to IT strategy / vision. The flow goes something like this: Business Strategy –> Business / Application / Information / Technology Architecture –> SOA Reference Architecture –> SOA Functional Architecture.  Governance is imbued throughout to help map, measure and verify the business-to-IT coherence. With those in place, then (and only then) can SOA fulfill it’s potential to be more that an integration strategy, more than a reuse strategy; but also a foundation for tying the results of IT to business vision. Fortunately, EA is a an ongoing process that it is never too late to get started with an understanding of frameworks such as TOGAF, FEA, or OEAF.  Also, EA is never ending in that it always needs to be apply, even once a full-blown Enterprise Architecture is established it needs to be constantly evolved.  For those who are getting deeper into EA as a discipline, there is plenty runway to grow as your company/customer begins to look more seriously at EA. I will close with a pointer to a Great Book I have recently read on this subject: Enterprise Architecture as Strategy (http://www.amazon.com/Enterprise-Architecture-Strategy-Foundation-Execution/dp/1591398398/ref=sr_1_1?ie=UTF8&s=books&qid=1268842865&sr=1-1)

• Juju Zookeeper & Provisioning Agent Not Deployed

• Is this a secure solution for RESTful authentication?

  - by Chad Johnson

  I need to quickly implement a RESTful authentication system for my JavaScript application to use. I think I understand how it should work, but I just want to double check. Here's what I'm thinking -- what do you guys think? Database schema users id : integer first_name : varchar(50) last_name : varchar(50) password : varchar(32) (MD5 hashed) etc. user_authentications id : integer user_id : integer auth_token : varchar(32) (AES encrypted, with keys outside database) access_token : varchar(32) (AES encrypted, with keys outside database) active : boolean Steps The following happens over SSL. I'm using Sinatra for the API. JavaScript requests authentication via POST to /users/auth/token. The /users/auth/token API method generates an auth_token hash, creates a record in user_authentications, and returns auth_token. JavaScript hashes the user's password and then salts it with auth_token -- SHA(access_token + MD5(password)) POST the user's username and hashed+salted password to /users/auth/authenticate. The /users/auth/authenticate API method will verify that SHA(AES.decrypt(access_token) + user.password) == what was received via POST. The /users/auth/authenticate will generate, AES encrypt, store, and return an access token if verification is successful; otherwise, it will return 401 Unauthorized. For any future requests against the API, JavaScript will include access_token, and the API will find the user account based on that.

• Meta-licensing of applications

  - by Gene

  I'm currently evaluating license management solutions for our customized and project-based applications, which are supported by a single server in the intranet of the customer. The applications use common functionality provided by the server (session handling, data synchronization, management capabilities, etc) and are installed on mobile devices. We allow our customers to run the applications on X devices and want to check on the server, whether the customer sticks to this limit (based on the sessions). We don't want licensing software to be installed on the devices itself (for example providing X serials to the customer) nor do we want to host an additional server for licensing in the intranet of the customer. If a client connects, our server should load the license for the application running on the client and verify, that there are sessions left. The licensing managers I looked at (12 products so far) focus on the application itself and don't allow me to implement such a floating behavior as described above. For example, this software could easily be used to create a "Standard Edition" or a "Professional Edition" of our server software, which is not our intention. In XHEO DeployLX there is a "Session Limit", which allows to limit the license to the currently established sessions in ASP.NET, which comes very close to my needs. I'm currently thinking of implementing a custom solution, which allows me to load and enforce custom-defined licenses per application on the server-side and a simple editor to define such licenses (which would contain a type and the limit itself), but I would appreciate an existing, easy to integrate commercial solution. I think it could be possible to use DeployLX for this task, but I would spend a lot of money for implementing most of the solution myself (except for the editor). Thanks in advance for any suggestions or hints. Gene

• What is a “pretty and proper OO” way for handling sessions and authentication?

  - by asdfqwer

  Is coupling these two concepts a bad approach? As of right now I'm delegating all session handling and whether or not a user desires to logout in my config.inc file. As I was writing my Auth class I started wondering whether or not my Auth class should be taking care of most of the logic in my config.inc. Regardless, I'm sure there's a more elegant way of handling this... Here is what I have in my config.inc (also a large chunk of this code is based on a reply I found on SO except I can't find the source ._.): ini_set('session.name', 'SID'); # session management session_set_cookie_params(24*60*60); // set SID cookie lifetime session_start(); if(isset($_SESSION['LOGOUT']) { session_destroy(); // destroy session data $_SESSION = array(); // destroy session data sanity check setcookie('SID', '', time() - 24*60*60); // destroy session cookie data #header('Location: '.DOCROOT); } elseif(isset($_SESSION['SID_AUTH'])) { // verify user has authenticated if (!isset($_SESSION['SID_CREATED'])) { $_SESSION['SID_CREATED'] = time(); } elseif (time() - $_SESSION['SID_CREATED'] > 6*60*60) { // session started more than 6 hours ago session_regenerate_id(); // reset SID value $_SESSION['SID_CREATED'] = time(); // update creation time } if (isset($_SESSION['SID_MODIFIED']) && (time() - $_SESSION['SID_MODIFIED'] > 12*60*60)) { // last request was more than 12 hours ago session_destroy(); // destroy session data $_SESSION = array(); // destroy session data sanity check setcookie('SID', '', time() - 24*60*60); // destroy session cookie data } $_SESSION['SID_MODIFIED'] = time(); // update last activity time stamp }

• Configure SQL Server to Allow Remote Connections

  - by Ben Griswold

  Okay. This post isn’t about configuring SQL to allow remote connections, but wait, I still may be able to help you out. "A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 – Could not open a connection to SQL Server)" I love this exception. It summarized the issue and leads you down a path to solving the problem.  I do wish the bit about allowing remote connections was left out of the message though. I can’t think of a time when having remote connections disabled caused me grief.  Heck, I can’t ever remember how to enable remote connections unless I Google for the answer. Anyway, 9 out of 10 times, SQL Server simply isn’t running.  That’s why the exception occurs.  The next time this exception pops up, open up the services console and make sure SQL Server is started.  And if that’s not the problem, only then start digging into the other possible reasons for the failure.

• Coding in large chunks ... Code verification skills

  - by Andrew

  As a follow up to my prev question: What is the best aproach for coding in a slow compilation environment To recap: I am stuck with a large software system with which a TDD ideology of "test often" does not work. And to make it even worse the features like pre-compiled headers/multi-threaded compilation/incremental linking, etc is not available to me - hence I think that the best way out would be to add the extensive logging into the system and to start "coding in large chunks", which I understand as code for a two-three hours first (as opposed to 15-20 mins in TDD) - thoroughly eyeball the code for a 15 minutes and only after all that do the compilation and run the tests. As I have been doing TDD for a quite a while, my code eyeballing / code verification skills got rusty (you don't really need this that much if you can quickly verify what you've done in 5 seconds by running a test or two) - so I am after a recommendations on how to learn these source code verification/error spotting skills again. I know I was able to do that easily some 5-10 years ago when I din't have much support from the compiler/unit testing tools I had until recently, thus there should be a way to get back to the basics.

• Ambiguous in the namespace problem

  - by Agha Usman Ahmed

  From the last few days, I was ignoring an error that keep coming at the compile time. I spent some two hours on it before but didn’t get it work. The error is quit confusing and of course difficult to manage. 'ApplicationSettingsBase' is ambiguous in the namespace 'System.Configuration' 'MailMessage' is ambiguous in the namespace 'System.Net.Mail' And there are couple of other similar errors that is pointing to some ambiguous references in my project.  The confusing part is that the MailMessage object throws similar error when you are importing the old and new email namespace. For example, Imports System.Web.Mail Imports System.Net.Mail So if you are only encountering ambiguous problem in MailMessage object. It is more possible that you have define both the namespaces in your code behind which is actually confusing the compiler about your referencing object. The quick solve for this problem is that remove Imports System.Web.Mail and it should work smooth. But with me, I never used the old asp.net mail namespace in my project. Then I start looking at my references and luckily I found the problem there. Follow the steps below to investigate the issue 1. Go to your project 2. Then references 3. Right click on “System” and see properties. it should point to the following path x:\Windows\Microsoft.NET\Framework\v2.0.50727\System.dll Where x is name of your operating system directory. This was the problem with my project. I had my operating system install on “D” drive and some how it is pointing to “C” drive which is the root cause of this problem. After that I verify all my references and found 5 –6 assemblies that are pointing to wrong path and get it worked. Also note, the problem can occur in any type of project either it is website , web application etc.

• [MINI HOW-TO] Remove a Network Computer from Windows Home Server

  - by Mysticgeek

  One of the cool features of Windows Home Server is the ability to backup and monitor the computers on your network. If you no longer need a machine on to be monitored or backed up, here we show you how to remove it. Remove Computer from WHS The process if straight-forward and basic –Open Windows Home Server Console and click on Computers & Backup. Right-click on the computer that you no longer need and click Remove. You’ll be prompted to verify that you want to remove the machine and delete all of its backup data. Check the box I am sure I want to remove this computer then click the Remove button. That’s all there is to it! The computer and all of its backup data is removed. Remember that if you remove a computer, all of its backup data will be deleted as well. If you no longer have the computer, you probably don’t need the backed up data anyway, but you’ll want to be sure you no longer need it before removing it.

• Is my sequence diagram correct?

  - by Dummy Derp

  NOTE: I am self studying UML so I have nobody to verify my diagrams and hence I am posting here, so please bear with me. This is the problem I got from some PDF available on Google that simply had the following problem statement: Problem Statement: A library contains books and journals. The task is to develop a computer system for borrowing books. In order to borrow a book the borrower must be a member of the library. There is a limit on the number of books that can be borrowed by each member of the library. The library may have several copies of a given book. It is possible to reserve a book. Some books are for short term loans only. Other books may be borrowed for 3 weeks. Users can extend the loans. Draw a use case diagram for a library. I already drew the Use Case diagram and had it checked by a community member. This time I drew sequence diagrams for borrowing a book and extending the date of return. Please let me know if they are correct. I drew them using Visual Paradigm and I dont know how to keep a control of the sequence numbers. If you do, please let me know :) Diagrams

• How to open a VirtualBox (.VDI) Virtual Machine

  - by [email protected]

   How to open a .VDI Virtual MachineSometimes someone share with us one Virtual machine with extension .VDI, after that we can wonder how and what with?Well the answer is... It is a VirtualBox - Virtual Machine. If you have not downloaded it you can do this easily, just follow this post.http://listeningoracle.blogspot.com/2010/04/que-es-virtualbox.htmlorhttp://oracleoforacle.wordpress.com/2010/04/14/ques-es-virtualbox/Ok, Now with VirtualBox Installed open it and proceed with the following:1. Open the Virtual File Manager. 2. Click on Actions ? Add and select the .VDI fileClick "Ok"3.  A new Virtual machine will be displayed, (in this Case, an OEL5 32GB Virtual Machine is available.)4. This step is important. Once you have open the settings, under General option click the advanced settings. Here you must change the default directory to save your Snapshots; my recommendation set it to the same directory where the .Vdi file is. Otherwise you can have the same Virtual Machine and its snapshots in different paths.5. Now Click on System, and proceed to assign the correct memory and define the processors for the Virtual machine. Note: Enable  "Enable IO APIC" if you are planning to assign more than one CPU to the Virtual Machine.6. Associated the storage disk to the Virtual machineThe disk must be selected as IDE Primary Master. 7. Well you can verify the other options, but with these changes you will be able to start the VM. Note: Sometime the VM owner may share some instructions, if so follow his instructions.8. Click Ok and Push Start Button, and enjoy your Virtual Machine

• OCS 2007 Access Edge Server Certificate issue

  - by BWCA

  We are currently building additional OCS 2007 R2 Access Edge Servers to handle additional capacity.  We ran into a SSL certificate issue when we were setting up the servers. Before running the steps to Deploy an Edge Server, we successfully imported our SSL certificate that we use for external access on all of the new servers.  After successfully completing the first three Deploy Edge Server steps one one of the new servers, we started working on Step 4: Configure Certificates for the Edge Server.  After selecting Assign an existing certificate from the common tasks list and clicking Next to select a certificate, there were no certificates listed as shown below.   The first thing we did was to use the Certificates mmc snap-in to review the SSL certificate information.  We noticed in the General tab that Windows does not have enough information to verify this certificate and in the Certification Path that the issuer of this certificate could not be found for the SSL certificate that we imported successfully earlier.     While troubleshooting, we learned that we could not access the URL for the certificate’s CRL to download the CRL file due to restrictive firewall rules between the new OCS 2007 R2 Access Edge Servers and the Internet. After modifying the firewall rules, we were able to download the CRL file and when we reran Step 4 to assign an existing certificate, the certificate was listed.

• Added key, but still getting "gpg: Can't check signature: public key not found"

  Trying to download Django source package using dget and the .dsc file from here. Then dget fails to verify the source, because it is missing a public key. $ dget https://launchpad.net/ubuntu... [...] dscverify: python-django_1.4.1-2.dsc failed signature check: gpg: Signature made Tue 21 Aug 2012 09:12:04 CEST using RSA key ID F2AC729A gpg: Can't check signature: public key not found Validation FAILED!!

• How do I refresh Disk Utility?

  - by detly

  I do a lot of live system building, which eventually involves imaging a USB drive with the built binary image: dd if=binary.img of=/dev/sdX sync ...where /dev/sdX is a USB drive. As part of my workflow, I like to have Ubuntu's Disk Utility open so I can verify the drive letter and unmount anything that gets mounted automatically. I also use it to create extra partitions for persistence. The trouble is, after writing the image to the device — and even after the sync operation — Disk Utility doesn't show the new partition. It just shows free space. GParted sees it and fdisk sees it. Even after closing and opening Disk Utility, it still shows only free space. If I click "Safe Removal" and physically unplug and replug the USB drive, Disk Utility will then see the partition. Why do I need to remove and re-insert the drive for Disk Utility to see the partitions on it? Can I force Disk Utility to update its information without needing to do this? (using Disk Utility 3.0.2 under Ubuntu 11.10.)

• Programming Practice/Test Contest?

  - by Emmanuel

  My situation: I'm on a programming team, and this year, we want to weed out the weak link by making a competition to get the best coder from our group of candidates. Focus is on IEEExtreme-like contests. What I've done: I've been trying already for 2 weeks to get a practice or test site, like UVa or codechef. The plan after I find one: Send them (the candidates) a list of direct links to the problems (making them the "contest's problem list) get them to email me their correct answers' code at the time the judge says they have solved it and accept the fastest one into the team. Issues: We had practiced on UVa already (on programming challenges too), so our former teammate (which will be in the candidate group) already has an advantage if we used it. Codechef has all it's answers public, and since it shows the latest ones it will be extremely hard to verify if the answer was copied. And I've found other sites, like SPOJ, but they share at least some problems with codechef, making them inherit the issue of Codechef So, what alternatives do you think there are? Any site that may work? Any place to get all stuff to set up a Mooshak or similar contest (as in the stuff to get the problems, instructions to set up the server itself are easy to google)? Any other idea?

• Duck checker in Python: does one exist?

  - by elliot42

  Python uses duck-typing, rather than static type checking. But many of the same concerns ultimately apply: does an object have the desired methods and attributes? Do those attributes have valid, in-range values? Whether you're writing constraints in code, or writing test cases, or validating user input, or just debugging, inevitably somewhere you'll need to verify that an object is still in a proper state--that it still "looks like a duck" and "quacks like a duck." In statically typed languages you can simply declare "int x", and anytime you create or mutate x, it will always be a valid int. It seems feasible to decorate a Python object to ensure that it is valid under certain constraints, and that every time that object is mutated it is still valid under those constraints. Ideally there would be a simple declarative syntax to express "hasattr length and length is non-negative" (not in those words. Not unlike Rails validators, but less human-language and more programming-language). You could think of this as ad-hoc interface/type system, or you could think of it as an ever-present object-level unit test. Does such a library exist to declare and validate constraint/duck-checking on Python-objects? Is this an unreasonable tool to want? :) (Thanks!) Contrived example: rectangle = {'length': 5, 'width': 10} # We live in a fictional universe where multiplication is super expensive. # Therefore any time we multiply, we need to cache the results. def area(rect): if 'area' in rect: return rect['area'] rect['area'] = rect['length'] * rect['width'] return rect['area'] print area(rectangle) rectangle['length'] = 15 print area(rectangle) # compare expected vs. actual output! # imagine the same thing with object attributes rather than dictionary keys.

• How do I choose a package format for Linux software distribution?

  - by Ian C.

  We have a Java-based application that, to date, we've been distributing as a tarball with instructions for deploying. It's mostly self-contained so deployment is fairly straight-forward: Untar on the disk you'd like it to live on; Make sure Java is in your path and a suitable distro and version; Verify ownership and group on all the files Start up the server processes with our start script If the user wants to get in to start-on-boot stuff with SysV we have some written instructions and a template init file for it in our tarball. We'd like to make this installation process a little more seamless; take care of the permissions and the init script deployment. We're also going to start bundling our own JRE with the application so that we're mostly free of external dependencies. The question we're faced with now is: how do we pick a package format for distribution? Is RPM the standard? Can all package management tools deal with it now? Our clients primarily run RHEL and CentOS, but we do have some using SuSE and even Debian. If we can pick a distro-agnostic format we'd prefer that. What about a self-extracting shell script? Something akin to how Java is distributed. If we're dependency-free would the self-extracting script be sufficient? What features or conveniences would we lose out on going with the script versus a proper package format meant for use by a package manager?

If the person is not a member, the book will not be issued to them for taking away, rather they will have to sit and read in the library. 2. Extending loan: Some books will be lent for 3 weeks while others will be lent for more than 3 weeks in which case the person borrowing has to come to the library and get the date extended. There is a limit on how much the user can extend the date of a particular book.
