Alternate Payments We've seen several alternate payment schemes emerge over the last two years, and 2011 may be the year one of them takes hold. Any competition that can drive down fees will be good for everyone. I'm betting that Apple will add NFC chips to their next version of the iPhone, then enable payments in stores using iTunes accounts on the backend. Paypal will continue to make inroads, and Isis will announce a pilot. The iPhone 4S did not contain an NFC chip, so we’ll have to continuing waiting for the iPhone 5. PayPal announced its moving into in-store payments, and Google launched its wallet in selected cities.  Overall I think the payment scene is heating up and that trend will continue. 2. Engineered Systems The industry is moving toward purpose-built appliances that are optimized across the entire stack. Oracle calls these "engineered systems" and the first two examples are Exadata and Exalogic, but there are other examples from other vendors. These are particularly important to the retail industry because of the volume of data that must be processed. There should be continued adoption in 2011. Oracle reports that Exadata is its fasting growing product, and at the recent OpenWorld it announced the SuperCluster and Exalytics products, both continuing the engineered systems trend. SAP’s HANA continues to receive attention, and IBM also seems to be moving in this direction. 3. Social Analytics There are lots of tools that provide insight into how a brand is perceived across popular internet sites, but as far as I know, these tools are not industry specific. The next step needs to mine the data and determine how it should influence retail operations. The data needs to help retailers determine how they create promotions, which products to stock, and how to keep consumers engaged. Social data alone does not provide the answers, but its one more data point that will help retailers make better decisions. Look for some vendor consolidation to help make this happen. In March, Salesforce.com acquired leading social monitoring vendor Radian6 and followed up with acquisitions of Heroku and Model Metrics. The notion of Social CRM seems to be going more mainstream now. 4. 2-D Barcodes Look for more QRCodes on shelf-tags, in newspaper circulars, and on billboards. It's a great portal from the physical world into the digital one that buys us time until augmented reality matures further. Nobody wants to type "www", backslash, and ".com" on their phones. QRCodes are everywhere. ‘Nuff said. 5. In the words of Microsoft, "To the Cloud!" My favorite "cloud application" is Evernote. If you take notes on your work laptop, you will inevitably need those notes on your home PC. And if you manage to solve that problem, you'll need to access them from your mobile phone. Evernote stores your notes in the cloud and provides easy ways to access them. Being able to access a service from anywhere and not having to worry about backups, upgrades, etc. is great. Retailers will start to rely on cloud services, both public and private, in the coming year. There were no shortage of announcements in this area: Amazon’s cloud-based Kindle Fire, Apple’s iCloud, Oracle’s Public Cloud, etc. I saw an interesting presentation showing how BevMo moved their systems to the cloud.  Seems like retailers are starting to consider the cloud for specific uses. 6. F-CommerceTop of Form Move over "E" and "M" so we can introduce "F-Commerce," which should go mainstream in 2011. Already several retailers have created small stores on Facebook, and it won't be long before Facebook becomes a full-fledged channel in the omni-channel world of retail. The battle between Facebook and Google will heat up over retail, where both stand to make lots of money. JCPenney and ASOS both put their entire catalogs on Facebook, and lots of other retailers have connected Facebook to their e-commerce site. I still think selling from the newsfeed is the best approach, and several retailers are trying that approach as well. I just don’t see Google+ as a threat to Facebook, so I think that battle is over.  I called 2011 The Year of F-Commerce, and that was probably accurate. Its good to look back at predictions, but we also have to think about what was missed.  I didn't see Amazon entering the tablet business with such a splash, although in hindsight it was obvious. Nor did I think HP would fall so far so fast.  Look for my 2012 predictions coming soon.

• Google Analytics on Android

  - by pjv

  There is a specific and official analytics SDK for native Android apps (note that I'm not talking about webpages in apps on a phone). This library basically sends pages and events to Google Analytics and you can view your analytics in exactly the same dashboard as for websites. Since my background is apps rather than websites, and since a lot of the Google Analytics terminology seems particularly inapplicable to a native app, I need some pointers. Please discuss my remarks, provide some clarification where you think I'm off-track, and above all share good experiences! 1. Page Views Pages mostly can match different Activities (and Dialogs) being displayed. Activities can be visible behind non-full-screen Activities however, though only the top-level Activity can be interacted. This sort-off clashes with a "(page) view". You'd also want at least one page view for each visit and therefore put one page view tracker in the Application class. However this does not constitute a window or sorts. Usually an Activity will open at the same time, so the time spent on that page will have been 0. This will influence your "time spent" statistics. How are these counted anyway? Moreover, there is a loose coupling between the Activities, by means of Intents. A user can, much like on any website, step in at any Activity, although usually this then concerns resuming the application where he left off. This makes that the hierarchy of Activities usually is very flat. And since there are no url's involved. What meaning would using slashes in page titles have, such as "/Home"? All pages would appear on an equal level in the reports, so no content drilldown. Non-unique page views seem to be counted as some kind of indicator of successfulness: how often does the visitor revisit the page. When the user rotates the screen however usually an Activity resumes again, thus making it a new page view. This happens a lot. Maybe a well-thought-through placement of the call might solve this, or placing several, I'm not sure. How to deal with Page Views? 2. Events I'd say there are two sorts: A user event Something that happened, usually as an indirect consequence of the above. The latter particularly is giving me headaches. First of all, many events aren't written in code any more, but pieced logically together by means of Intents. This means that there is no place to put the analytics call. You'd either have to give up this advantage and start doing it the old-fashioned way in favor of good analytics, or, just be missing some events. Secondly, as a developer you're not so much interested in when a user clicks a button, but if the action that should have been performed really was performed and what the result was. There seems to be no clear way to get resulting data into Google Analytics (what's up with the integers? I want to put in Strings!). The same that applies to the flat pages hierarchy, also goes for the event categories. You could do "vertical" categories (topically, that is), but some code is shared "horizontally" and the tracking will be equally shared. Just as with the Intents mechanism, inheritance makes it hard for you to put the tracking in the right places at all times. And I can't really imagine "horizontal" categories. Unless you start making really small categories, such as all the items form the same menu in one category, I have a hard time grasping the concept. Finally, how do you deal with cancelling? Usually you both have an explicit cancel mechanism by ways of a button, as well as the implicit cancel when the "back"-button is pressed to leave the activity and there were no changes. The latter also applies to "saves", when the back button is pressed and there ARE changes. How are you consequently going to catch all these if not by doing all the "back"-button work yourself? How to deal with events? 3. Goals For goal types I have choice of: URL Destination, Time on Site, and Pages/Visit. Most apps don't have a funnel that leads the user to some "registration done" or "order placed" page. Apps have either already been bought (in which case you want to stimulate the user to love your app, so that he might bring on new buyers) or are paid for by in-app ads. So URL Destination is not a very important goal. Time on Site also seems troublesome. First, I have some doubt on how this would be measured. Second, I don't necessarily want my user to spend a lot of time in my already paid app, just be active and content. Equivalently, why not mention how frequent a user uses your app? Regarding Pages/Visit I already mentioned how screen orientation changes blow up the page view numbers. In an app I'd be most interested in events/visit to measure the user's involvement/activity. If he's intensively using the app then he must be loving it right? Furthermore, I also have some small funnels (that do not lead to conversion though) that I want to see streamlined. In my mind those funnels would end in events rather than page views but that seems not to be possible. I could also measure clickthroughs on in-app ads, but then I'd need to track those as Page Views rather than Events, in view of "URL Destination". What are smart goals for apps and how can you fit them on top of Analytics? 4. Optimisation Is there a smart way to manually do what "Website Optimiser" does for websites? Most importantly, how would I track different landing page designs? 5. Traffic Sources Referrals deal with installation time referrals, if you're smart enough to get them included. But perhaps I'd also want to get some data which third-party app sends users to my app to perform some actions (this app interoperability is possible via Intents). Many of the terminologies related to "Traffic Sources" seem totally meaningless and there is no possibility of connecting in AdSense. What are smart uses of this data? 6. Visitors Of the "Browser capabilities", "Network Properties" and "Mobile" tabs, many things are pointless as they have no influence on / relation with my mostly offline app that won't use flash anyway. Only if you drill down far enough, can you get to OS versions, which do matter a lot. I even forgot where you could check what exact Android devices visited. What are smart uses of this data? How can you make the relevant info more prominent? 7. Other No in-page analytics. I have to register my app as a web-url (What!?)?

• Windows Azure Virtual Machine Readiness and Capacity Assessment for SQL Server

  - by SQLOS Team

  Windows Azure Virtual Machine Readiness and Capacity Assessment for Windows Server Machine Running SQL Server With the release of MAP Toolkit 8.0 Beta, we have added a new scenario to assess your Windows Azure Virtual Machine Readiness. The MAP 8.0 Beta performs a comprehensive assessment of Windows Servers running SQL Server to determine you level of readiness to migrate an on-premise physical or virtual machine to Windows Azure Virtual Machines. The MAP Toolkit then offers suggested changes to prepare the machines for migration, such as upgrading the operating system or SQL Server. MAP Toolkit 8.0 Beta is available for download here Your participation and feedback is very important to make the MAP Toolkit work better for you. We encourage you to participate in the beta program and provide your feedback at [email protected] or through one of our surveys. Now, let’s walk through the MAP Toolkit task for completing the Windows Azure Virtual Machine assessment and capacity planning. The tasks include the following: Perform an inventory View the Windows Azure VM Readiness results and report Collect performance data for determine VM sizing View the Windows Azure Capacity results and report Perform an inventory: 1. To perform an inventory against a single machine or across a complete environment, choose Perform an Inventory to launch the Inventory and Assessment Wizard as shown below: 2. After the Inventory and Assessment Wizard launches, select either the Windows computers or SQL Server scenario to inventory Windows machines. HINT: If you don’t care about completely inventorying a machine, just select the SQL Server scenario. Click Next to Continue. 3. On the Discovery Methods page, select how you want to discover computers and then click Next to continue. Description of Discovery Methods: Use Active Directory Domain Services -- This method allows you to query a domain controller via the Lightweight Directory Access Protocol (LDAP) and select computers in all or specific domains, containers, or OUs. Use this method if all computers and devices are in AD DS. Windows networking protocols --  This method uses the WIN32 LAN Manager application programming interfaces to query the Computer Browser service for computers in workgroups and Windows NT 4.0–based domains. If the computers on the network are not joined to an Active Directory domain, use only the Windows networking protocols option to find computers. System Center Configuration Manager (SCCM) -- This method enables you to inventory computers managed by System Center Configuration Manager (SCCM). You need to provide credentials to the System Center Configuration Manager server in order to inventory the managed computers. When you select this option, the MAP Toolkit will query SCCM for a list of computers and then MAP will connect to these computers. Scan an IP address range -- This method allows you to specify the starting address and ending address of an IP address range. The wizard will then scan all IP addresses in the range and inventory only those computers. Note: This option can perform poorly, if many IP addresses aren’t being used within the range. Manually enter computer names and credentials -- Use this method if you want to inventory a small number of specific computers. Import computer names from a files -- Using this method, you can create a text file with a list of computer names that will be inventoried. 4. On the All Computers Credentials page, enter the accounts that have administrator rights to connect to the discovered machines. This does not need to a domain account, but needs to be a local administrator. I have entered my domain account that is an administrator on my local machine. Click Next after one or more accounts have been added. NOTE: The MAP Toolkit primarily uses Windows Management Instrumentation (WMI) to collect hardware, device, and software information from the remote computers. In order for the MAP Toolkit to successfully connect and inventory computers in your environment, you have to configure your machines to inventory through WMI and also allow your firewall to enable remote access through WMI. The MAP Toolkit also requires remote registry access for certain assessments. In addition to enabling WMI, you need accounts with administrative privileges to access desktops and servers in your environment. 5. On the Credentials Order page, select the order in which want the MAP Toolkit to connect to the machine and SQL Server. Generally just accept the defaults and click Next. 6. On the Enter Computers Manually page, click Create to pull up at dialog to enter one or more computer names. 7. On the Summary page confirm your settings and then click Finish. After clicking Finish the inventory process will start, as shown below: Windows Azure Readiness results and report After the inventory progress has completed, you can review the results under the Database scenario. On the tile, you will see the number of Windows Server machine with SQL Server that were analyzed, the number of machines that are ready to move without changes and the number of machines that require further changes. If you click this Azure VM Readiness tile, you will see additional details and can generate the Windows Azure VM Readiness Report. After the report is generated, select View | Saved Reports and Proposals to view the location of the report. Open up WindowsAzureVMReadiness* report in Excel. On the Windows tab, you can see the results of the assessment. This report has a column for the Operating System and SQL Server assessment and provides a recommendation on how to resolve, if there a component is not supported. Collect Performance Data Launch the Performance Wizard to collect performance information for the Windows Server machines that you would like the MAP Toolkit to suggest a Windows Azure VM size for. Windows Azure Capacity results and report After the performance metrics are collected, the Azure VM Capacity title will display the number of Virtual Machine sizes that are suggested for the Windows Server and Linux machines that were analyzed. You can then click on the Azure VM Capacity tile to see the capacity details and generate the Windows Azure VM Capacity Report. Within this report, you can view the performance data that was collected and the Virtual Machine sizes.   MAP Toolkit 8.0 Beta is available for download here Your participation and feedback is very important to make the MAP Toolkit work better for you. We encourage you to participate in the beta program and provide your feedback at [email protected] or through one of our surveys.

• Metrics - A little knowledge can be a dangerous thing (or 'Why you're not clever enough to interpret metrics data')

  - by Jason Crease

  At RedGate Software, I work on a .NET obfuscator  called SmartAssembly.  Various features of it use a database to store various things (exception reports, name-mappings, etc.) The user is given the option of using either a SQL-Server database (which requires them to have Microsoft SQL Server), or a Microsoft Access MDB file (which requires nothing). MDB is the default option, but power-users soon switch to using a SQL Server database because it offers better performance and data-sharing. In the fashionable spirit of optimization and metrics, an obvious product-management question is 'Which is the most popular? SQL Server or MDB?' We've collected data about this fact, using our 'Feature-Usage-Reporting' technology (available as part of SmartAssembly) and more recently our 'Application Metrics' technology: Parameter Number of users % of total users Number of sessions Number of usages SQL Server 28 19.0 8115 8115 MDB 114 77.6 1449 1449 (As a disclaimer, please note than SmartAssembly has far more than 132 users . This data is just a selection of one build) So, it would appear that SQL-Server is used by fewer users, but more often. Great. But here's why these numbers are useless to me: Only the original developers understand the data What does a single 'usage' of 'MDB' mean? Does this happen once per run? Once per option change? On clicking the 'Obfuscate Now' button? When running the command-line version or just from the UI version? Each question could skew the data 10-fold either way, and the answers only known by the developer that instrumented the application in the first place. In other words, only the original developer can interpret the data - product-managers cannot interpret the data unaided. Most of the data is from uninterested users About half of people who download and run a free-trial from the internet quit it almost immediately. Only a small fraction use it sufficiently to make informed choices. Since the MDB option is the default one, we don't know how many of those 114 were people CHOOSING to use the MDB, or how many were JUST HAPPENING to use this MDB default for their 20-second trial. This is a problem we see across all our metrics: Are people are using X because it's the default or are they using X because they want to use X? We need to segment the data further - asking what percentage of each percentage meet our criteria for an 'established user' or 'informed user'. You end up spending hours writing sophisticated and dubious SQL queries to segment the data further. Not fun. You can't find out why they used this feature Metrics can answer the when and what, but not the why. Why did people use feature X? If you're anything like me, you often click on random buttons in unfamiliar applications just to explore the feature-set. If we listened uncritically to metrics at RedGate, we would eliminate the most-important and more-complex features which people actually buy the software for, leaving just big buttons on the main page and the About-Box. "Ah, that's interesting!" rather than "Ah, that's actionable!" People do love data. Did you know you eat 1201 chickens in a lifetime? But just 4 cows? Interesting, but useless. Often metrics give you a nice number: '5.8% of users have 3 or more monitors' . But unless the statistic is both SUPRISING and ACTIONABLE, it's useless. Most metrics are collected, reviewed with lots of cooing. and then forgotten. Unless a piece-of-data could change things, it's useless collecting it. People get obsessed with significance levels The first things that lots of people do with this data is do a t-test to get a significance level ("Hey! We know with 99.64% confidence that people prefer SQL Server to MDBs!") Believe me: other causes of error/misinterpretation in your data are FAR more significant than your t-test could ever comprehend. Confirmation bias prevents objectivity If the data appears to match our instinct, we feel satisfied and move on. If it doesn't, we suspect the data and dig deeper, plummeting down a rabbit-hole of segmentation and filtering until we give-up and move-on. Data is only useful if it can change our preconceptions. Do you trust this dodgy data more than your own understanding, knowledge and intelligence?  I don't. There's always multiple plausible ways to interpret/action any data Let's say we segment the above data, and get this data: Post-trial users (i.e. those using a paid version after the 14-day free-trial is over): Parameter Number of users % of total users Number of sessions Number of usages SQL Server 13 9.0 1115 1115 MDB 5 4.2 449 449 Trial users: Parameter Number of users % of total users Number of sessions Number of usages SQL Server 15 10.0 7000 7000 MDB 114 77.6 1000 1000 How do you interpret this data? It's one of: Mostly SQL Server users buy our software. People who can't afford SQL Server tend to be unable to afford or unwilling to buy our software. Therefore, ditch MDB-support. Our MDB support is so poor and buggy that our massive MDB user-base doesn't buy it.  Therefore, spend loads of money improving it, and think about ditching SQL-Server support. People 'graduate' naturally from MDB to SQL Server as they use the software more. Things are fine the way they are. We're marketing the tool wrong. The large number of MDB users represent uninformed downloaders. Tell marketing to aggressively target SQL Server users. To choose an interpretation you need to segment again. And again. And again, and again. Opting-out is correlated with feature-usage Metrics tends to be opt-in. This skews the data even further. Between 5% and 30% of people choose to opt-in to metrics (often called 'customer improvement program' or something like that). Casual trial-users who are uninterested in your product or company are less likely to opt-in. This group is probably also likely to be MDB users. How much does this skew your data by? Who knows? It's not all doom and gloom. There are some things metrics can answer well. Environment facts. How many people have 3 monitors? Have Windows 7? Have .NET 4 installed? Have Japanese Windows? Minor optimizations.  Is the text-box big enough for average user-input? Performance data. How long does our app take to start? How many databases does the average user have on their server? As you can see, questions about who-the-user-is rather than what-the-user-does are easier to answer and action. Conclusion Use SmartAssembly. If not for the metrics (called 'Feature-Usage-Reporting'), then at least for the obfuscation/error-reporting. Data raises more questions than it answers. Questions about environment are the easiest to answer.

• Let your Signature Experience drive IT-decision making

  - by Tania Le Voi

  Today’s CIO job description:  ‘’Align IT infrastructure and solutions with business goals and objectives ; AND while doing so reduce costs; BUT ALSO, be innovative, ensure the architectures are adaptable and agile as we need to act today on the changes that we may request tomorrow.”   Sound like an unachievable request? The fact is, reality dictates that CIO’s are put under this type of pressure to deliver more with less. In a past career phase I spent a few years as an IT Relationship Manager for a large Insurance company. This is a role that we see all too infrequently in many of our customers, and it’s a shame.  The purpose of this role was to build a bridge, a relationship between IT and the business. Key to achieving that goal was to ensure the same language was being spoken and more importantly that objectives were commonly understood - hence service and projects were delivered to time, to budget and actually solved the business problems. In reality IT and the business are already married, but the relationship is most often defined as ‘supplier’ of IT rather than a ‘trusted partner’. To deliver business value they need to understand how to work together effectively to attain this next level of partnership. The Business cannot compete if they do not get a new product to market ahead of the competition, or for example act in a timely manner to address a new industry problem such as a legislative change. An even better example is when the Application or Service fails and the Business takes a hit by bad publicity, being trending topics on social media and losing direct revenue from online channels. For this reason alone Business and IT need the alignment of their priorities and deliverables now more than ever! Take a look at Forrester’s recent study that found ‘many IT respondents considering themselves to be trusted partners of the business but their efforts are impaired by the inadequacy of tools and organizations’.  IT Meet the Business; Business Meet IT So what is going on? We talk about aligning the business with IT but the reality is it’s difficult to do. Like any relationship each side has different goals and needs and language can be a barrier; business vs. technology jargon! What if we could translate the needs of both sides into actionable information, backed by data both sides understand, presented in a meaningful way?  Well now we can with the Business-Driven Application Management capabilities in Oracle Enterprise Manager 12cR2! Enterprise Manager’s Business-Driven Application Management capabilities provide the information that IT needs to understand the impact of its decisions on business criteria.  No longer does IT need to be focused solely on speeds and feeds, performance and throughput – now IT can understand IT’s impact on business KPIs like inventory turns, order-to-cash cycle, pipeline-to-forecast, and similar.  Similarly, now the line of business can understand which IT services are most critical for the KPIs they care about. There are a good deal of resources on Oracle Technology Network that describe the functionality of these products, so I won’t’ rehash them here.  What I want to talk about is what you do with these products. What’s next after we meet? Where do you start? Step 1:  Identify the Signature Experience. This is THE business process (or set of processes) that is core to the business, the one that drives the economic engine, the process that a customer recognises the company brand for, reputation, the customer experience, the process that a CEO would state as his number one priority. The crème de la crème of your business! Once you have nailed this it gets easy as Enterprise Manager 12c makes it easy. Step 2:  Map the Signature Experience to underlying IT.  Taking the signature experience, map out the touch points of the components that play a part in ensuring this business transaction is successful end to end, think of it like mapping out a critical path; the applications, middleware, databases and hardware. Use the wealth of Enterprise Manager features such as Systems, Services, Business Application Targets and Business Transaction Management (BTM) to assist you. Adding Real User Experience Insight (RUEI) into the mix will make the end to end customer satisfaction story transparent. Work with the business and define meaningful key performance indicators (KPI’s) and thresholds to enable you to report and action upon. Step 3:  Observe the data over time.  You now have meaningful insight into every step enabling your signature experience and you understand the implication of that experience on your underlying IT.  Watch if for a few months, see what happens and reconvene with your business stakeholders and set clear and measurable targets which can re-define service levels.  Step 4:  Change the information about which you and the business communicate.  It’s amazing what happens when you and the business speak the same language.  You’ll be able to make more informed business and IT decisions. From here IT can identify where/how budget is spent whether on the level of support, performance, capacity, HA, DR, certification etc. IT SLA’s no longer need be focused on metrics such as %availability but structured around business process requirements. The power of this way of thinking doesn’t end here. IT staff get to see and understand how their own role contributes to the business making them accountable for the business service. Take a step further and appraise your staff on the business competencies that are linked to the service availability. For the business, the language barrier is removed by producing targeted reports on the signature experience core to the business and therefore key to the CEO. Chargeback or show back becomes easier to justify as the ‘cost of day per outage’ can be more easily calculated; the business will be able to translate the cost to the business to the cost/value of the underlying IT that supports it. Used this way, Oracle Enterprise Manager 12c is a key enabler to a harmonious relationship between the end customer the business and IT to deliver ultimate service and satisfaction. Just engage with the business upfront, make the signature experience visible and let Enterprise Manager 12c do the rest. In the next blog entry we will cover some of the Enterprise Manager features mentioned to enable you to implement this new way of working.

• WCF client endpoint identity - configuration question

  - by Roel

  Hi all, I'm having a strange situation here. I got it working, but I don't understand why. Situation is as follows: There is a WCF service which my application (a website) has to call. The WCF service exposes a netTcpBinding and requires Transport Security (Windows). Client and server are in the same domain, but on different servers. So generating a client results in the following config (mostly defaults) <system.serviceModel> <bindings> <netTcpBinding> <binding name="MyTcpEndpoint" ...> <reliableSession ordered="true" inactivityTimeout="00:10:00" enabled="false" /> <security mode="Transport"> <transport clientCredentialType="Windows" protectionLevel="EncryptAndSign"/> <message clientCredentialType="Windows" /> </security> </binding> </netTcpBinding> </bindings> <client> <endpoint address="net.tcp://localhost:xxxxx/xxxx/xxx/1.0" binding="netTcpBinding" bindingConfiguration="MyTcpEndpoint" contract="Service.IMyService" name="TcpEndpoint"/> </client> </system.serviceModel> When I run the website and make the call to the service, I get the following error: System.ServiceModel.Security.SecurityNegotiationException: Either the target name is incorrect or the server has rejected the client credentials. ---> System.Security.Authentication.InvalidCredentialException: Either the target name is incorrect or the server has rejected the client credentials. ---> System.ComponentModel.Win32Exception: The logon attempt failed --- End of inner exception stack trace --- at System.Net.Security.NegoState.EndProcessAuthentication(IAsyncResult result) at System.Net.Security.NegotiateStream.EndAuthenticateAsClient(IAsyncResult asyncResult) at System.ServiceModel.Channels.WindowsStreamSecurityUpgradeProvider.WindowsStreamSecurityUpgradeInitiator.InitiateUpgradeAsyncResult.OnCompleteAuthenticateAsClient(IAsyncResult result) at System.ServiceModel.Channels.StreamSecurityUpgradeInitiatorAsyncResult.CompleteAuthenticateAsClient(IAsyncResult result) --- End of inner exception stack trace --- Server stack trace: at System.ServiceModel.AsyncResult.End[TAsyncResult](IAsyncResult result) at System.ServiceModel.Channels.ServiceChannel.SendAsyncResult.End(SendAsyncResult result) at System.ServiceModel.Channels.ServiceChannel.EndCall(String action, Object[] outs, IAsyncResult result) .... Now, if I just alter the configuration of the client like so: <endpoint address="net.tcp://localhost:xxxxx/xxxx/xxx/1.0" binding="netTcpBinding" bindingConfiguration="MyTcpEndpoint" contract="Service.IMyService" name="TcpEndpoint"> <identity> <dns /> </identity> </endpoint> everything works and my server happily reports that it got called by the service account which hosts the AppPool for my website. All good. My question now is: why does this work? What does this do? I got to this solution by mere trial-and-error. To me it seems that all the <dns /> tag does is tell the client to use the default DNS for authentication, but doesn't it do that anyway? Thanks for providing me with some insight.

• Troubleshooting Windows Authentication problems (no challenge) in IIS 7.5?

  - by Aaronaught

  I know that there are thousands of reports of people having trouble getting Integrated Windows Authentication to work with IIS, but they all seem to lead to web pages that don't apply or solutions that I've already tried. I've deployed dozens of sites like this before, so either there's something bizarre going on with the server/configuration, or I've been looking at this too long and not seeing the obvious. Simply put, everything works perfectly on my local machine, but falls apart on the production server, which as far as I can tell has the exact same configuration. On the local machine: The machine is running Windows 7 Ultimate, Service Pack 1, IIS 7.5. The site has been tested successfully, using both IIS and the VS Web Development Server. The IIS site config has all authentication methods disabled except Windows Authentication. The local machine is not on any domain. The Providers set up are Negotiate and NTLM (not Negotiate:Kerberos). Extended Protection is Off. All browsers tested (IE, Firefox, Chrome) show the challenge prompt and allow me to log in to the localhost domain with my (local) Windows account. All browsers tested also work using an opaque local IP address - so the browsers themselves don't seem to care whether the site appears "local" or "remote". I've added a display line to the web page which shows the currently-logged-in user and it shows exactly what I would expect (whichever local user I logged in with). On the remote machine: The server is running Windows Server 2008 R2, IIS 7.5. Loading the web page results in an immediate 401.2 error: You are not authorized to view this page due to invalid authentication headers. No challenge prompt ever appears. The IIS site config has all authentication methods disabled except Windows Authentication. The remote machine is not on any domain. The Providers set up are Negotiate and NTLM (not Negotiate:Kerberos). Extended Protection is Off. On the remote machine (remote desktop session), the same error appears in Internet Explorer regardless of whether the domain is localhost or the external IP address. If I try to view the remote web site from my local machine, the error is still 401, but a slightly different 401. No subcode, with the text: Access is denied due to invalid credentials. The Windows Authentication IIS role feature is installed. The WindowsAuthentication Module is added (at the Server level). The exact same error occurs if I turn off Windows Authentication and enable Basic Authentication. The site does load if I turn off Windows Authentication and enable Anonymous (obviously). I've already followed all of the troubleshooting steps on Microsoft Support: Troubleshooting HTTP 401 errors in IIS I've already tried the workaround shown on another Microsoft support page (supposedly to force NTLM as the only method). Last but not least, I tried turning on FREB for 401.2 errors and the results don't seem to tell me anything useful, all I see is the following warning: MODULE_SET_RESPONSE_ERROR_STATUS ModuleName IIS Web Core Notification 2 HttpStatus 401 HttpReason Unauthorized HttpSubStatus 2 ErrorCode 2147942405 ConfigExceptionInfo Notification AUTHENTICATE_REQUEST ErrorCode Access is denied. (0x80070005) ...this seems to just be telling me what I already know (that it's simply rejecting the request instead of negotiating the credentials). The trace does indicate that the WindowsAuthentication module is correctly loaded because there is a NOTIFY_MODULE_START line with ModuleName = WindowsAuthentication (and various other ASP.NET follow-up events - [un]fortunately, no interesting errors or warnings here). Can anyone tell me what I might be missing here? Quick Update: I'm a little uncomfortable sending a whole Wireshark dump as it would reveal IPs, URLs and other stuff, but I did a side-by-side comparison of the HTTP responses from localhost and the remote server in Fiddler, and it seems fairly self-evident what the problem is: Localhost: HTTP/1.1 401 Unauthorized Cache-Control: private Content-Type: text/html; charset=utf-8 Server: Microsoft-IIS/7.5 WWW-Authenticate: Negotiate WWW-Authenticate: NTLM X-Powered-By: ASP.NET Date: Sat, 17 Dec 2011 23:42:34 GMT Content-Length: 6399 Proxy-Support: Session-Based-Authentication Remote: HTTP/1.1 401 Unauthorized Content-Type: text/html Server: Microsoft-IIS/7.5 X-Powered-By: ASP.NET Date: Sat, 17 Dec 2011 23:43:13 GMT Content-Length: 1293 Aside from a few seemingly-inconsequential differences like cache-control, the main difference is that the remote server is not sending the WWW-Authenticate headers back to the client. So, I guess that narrows the question down to: Why is IIS not sending WWW-Authenticate headers when Windows Authentication appears to be installed, loaded, and exclusively enabled?

• .NET SerialPort DataReceived event not firing

  - by Klay

  I have a WPF test app for evaluating event-based serial port communication (vs. polling the serial port). The problem is that the DataReceived event doesn't seem to be firing at all. I have a very basic WPF form with a TextBox for user input, a TextBlock for output, and a button to write the input to the serial port. Here's the code: public partial class Window1 : Window { SerialPort port; public Window1() { InitializeComponent(); port = new SerialPort("COM2", 9600, Parity.None, 8, StopBits.One); port.DataReceived += new SerialDataReceivedEventHandler(port_DataReceived); port.Open(); } void port_DataReceived(object sender, SerialDataReceivedEventArgs e) { Debug.Print("receiving!"); string data = port.ReadExisting(); Debug.Print(data); outputText.Text = data; } private void Button_Click(object sender, RoutedEventArgs e) { Debug.Print("sending: " + inputText.Text); port.WriteLine(inputText.Text); } } Now, here are the complicating factors: The laptop I'm working on has no serial ports, so I'm using a piece of software called Virtual Serial Port Emulator to setup a COM2. VSPE has worked admirably in the past, and it's not clear why it would only malfunction with .NET's SerialPort class, but I mention it just in case. When I hit the button on my form to send the data, my Hyperterminal window (connected on COM2) shows that the data is getting through. Yes, I disconnect Hyperterminal when I want to test my form's ability to read the port. I've tried opening the port before wiring up the event. No change. I've read through another post here where someone else is having a similar problem. None of that info has helped me in this case. EDIT: Here's the console version (modified from http://mark.michaelis.net/Blog/TheBasicsOfSystemIOPortsSerialPort.aspx): class Program { static SerialPort port; static void Main(string[] args) { port = new SerialPort("COM2", 9600, Parity.None, 8, StopBits.One); port.DataReceived += new SerialDataReceivedEventHandler(port_DataReceived); port.Open(); string text; do { text = Console.ReadLine(); port.Write(text + "\r\n"); } while (text.ToLower() != "q"); } public static void port_DataReceived(object sender, SerialDataReceivedEventArgs args) { string text = port.ReadExisting(); Console.WriteLine("received: " + text); } } This should eliminate any concern that it's a Threading issue (I think). This doesn't work either. Again, Hyperterminal reports the data sent through the port, but the console app doesn't seem to fire the DataReceived event. EDIT #2: I realized that I had two separate apps that should both send and receive from the serial port, so I decided to try running them simultaneously... If I type into the console app, the WPF app DataReceived event fires, with the expected threading error (which I know how to deal with). If I type into the WPF app, the console app DataReceived event fires, and it echoes the data. I'm guessing the issue is somewhere in my use of the VSPE software, which is set up to treat one serial port as both input and output. And through some weirdness of the SerialPort class, one instance of a serial port can't be both the sender and receiver. Anyway, I think it's solved.

• Is there a C pre-processor which eliminates #ifdef blocks based on values defined/undefined?

  - by Jonathan Leffler

  Original Question What I'd like is not a standard C pre-processor, but a variation on it which would accept from somewhere - probably the command line via -DNAME1 and -UNAME2 options - a specification of which macros are defined, and would then eliminate dead code. It may be easier to understand what I'm after with some examples: #ifdef NAME1 #define ALBUQUERQUE "ambidextrous" #else #define PHANTASMAGORIA "ghostly" #endif If the command were run with '-DNAME1', the output would be: #define ALBUQUERQUE "ambidextrous" If the command were run with '-UNAME1', the output would be: #define PHANTASMAGORIA "ghostly" If the command were run with neither option, the output would be the same as the input. This is a simple case - I'd be hoping that the code could handle more complex cases too. To illustrate with a real-world but still simple example: #ifdef USE_VOID #ifdef PLATFORM1 #define VOID void #else #undef VOID typedef void VOID; #endif /* PLATFORM1 */ typedef void * VOIDPTR; #else typedef mint VOID; typedef char * VOIDPTR; #endif /* USE_VOID */ I'd like to run the command with -DUSE_VOID -UPLATFORM1 and get the output: #undef VOID typedef void VOID; typedef void * VOIDPTR; Another example: #ifndef DOUBLEPAD #if (defined NT) || (defined OLDUNIX) #define DOUBLEPAD 8 #else #define DOUBLEPAD 0 #endif /* NT */ #endif /* !DOUBLEPAD */ Ideally, I'd like to run with -UOLDUNIX and get the output: #ifndef DOUBLEPAD #if (defined NT) #define DOUBLEPAD 8 #else #define DOUBLEPAD 0 #endif /* NT */ #endif /* !DOUBLEPAD */ This may be pushing my luck! Motivation: large, ancient code base with lots of conditional code. Many of the conditions no longer apply - the OLDUNIX platform, for example, is no longer made and no longer supported, so there is no need to have references to it in the code. Other conditions are always true. For example, features are added with conditional compilation so that a single version of the code can be used for both older versions of the software where the feature is not available and newer versions where it is available (more or less). Eventually, the old versions without the feature are no longer supported - everything uses the feature - so the condition on whether the feature is present or not should be removed, and the 'when feature is absent' code should be removed too. I'd like to have a tool to do the job automatically because it will be faster and more reliable than doing it manually (which is rather critical when the code base includes 21,500 source files). (A really clever version of the tool might read #include'd files to determine whether the control macros - those specified by -D or -U on the command line - are defined in those files. I'm not sure whether that's truly helpful except as a backup diagnostic. Whatever else it does, though, the pseudo-pre-processor must not expand macros or include files verbatim. The output must be source similar to, but usually simpler than, the input code.) Status Report (one year later) After a year of use, I am very happy with 'sunifdef' recommended by the selected answer. It hasn't made a mistake yet, and I don't expect it to. The only quibble I have with it is stylistic. Given an input such as: #if (defined(A) && defined(B)) || defined(C) || (defined(D) && defined(E)) and run with '-UC' (C is never defined), the output is: #if defined(A) && defined(B) || defined(D) && defined(E) This is technically correct because '&&' binds tighter than '||', but it is an open invitation to confusion. I would much prefer it to include parentheses around the sets of '&&' conditions, as in the original: #if (defined(A) && defined(B)) || (defined(D) && defined(E)) However, given the obscurity of some of the code I have to work with, for that to be the biggest nit-pick is a strong compliment; it is valuable tool to me. The New Kid on the Block Having checked the URL for inclusion in the information above, I see that (as predicted) there is an new program called Coan that is the successor to 'sunifdef'. It is available on SourceForge and has been since January 2010. I'll be checking it out...further reports later this year, or maybe next year, or sometime, or never.

• Play a sound based on the button pressed on the IPhone/xcode.

  - by slickplaid

  I'm trying to play a sound based on which button is pressed using AVAudioPlayer. (This is not a soundboard or fart app.) I have linked all buttons using this code in the header file: @interface appViewController : UIViewController <AVAudioPlayerDelegate> { AVAudioPlayer *player; UIButton *C4; UIButton *Bb4; UIButton *B4; UIButton *A4; UIButton *Ab4; UIButton *As4; UIButton *G3; UIButton *Gb3; UIButton *Gs3; UIButton *F3; UIButton *Fs3; UIButton *E3; UIButton *Eb3; UIButton *D3; UIButton *Db3; UIButton *Ds3; UIButton *C3; UIButton *Cs3; } @property (nonatomic, retain) AVAudioPlayer *player; @property (nonatomic, retain) IBOutlet UIButton *C4; @property (nonatomic, retain) IBOutlet UIButton *B4; @property (nonatomic, retain) IBOutlet UIButton *Bb4; @property (nonatomic, retain) IBOutlet UIButton *A4; @property (nonatomic, retain) IBOutlet UIButton *Ab4; @property (nonatomic, retain) IBOutlet UIButton *As4; @property (nonatomic, retain) IBOutlet UIButton *G3; @property (nonatomic, retain) IBOutlet UIButton *Gb3; @property (nonatomic, retain) IBOutlet UIButton *Gs3; @property (nonatomic, retain) IBOutlet UIButton *F3; @property (nonatomic, retain) IBOutlet UIButton *Fs3; @property (nonatomic, retain) IBOutlet UIButton *E3; @property (nonatomic, retain) IBOutlet UIButton *Eb3; @property (nonatomic, retain) IBOutlet UIButton *D3; @property (nonatomic, retain) IBOutlet UIButton *Db3; @property (nonatomic, retain) IBOutlet UIButton *Ds3; @property (nonatomic, retain) IBOutlet UIButton *C3; @property (nonatomic, retain) IBOutlet UIButton *Cs3; - (IBAction) playNote; @end Buttons are all linked to the event "playNote" in interfaceBuilder and each note is linked to the proper referencing outlet according to note name. All *.mp3 sound files are named after the UIButton name (IE- C3 == C3.mp3). In my implementation file, I have this to play a only one note when the C3 button is pressed: #import "sonicfitViewController.h" @implementation appViewController @synthesize C3, Cs3, D3, Ds3, Db3, E3, Eb3, F3, Fs3, G3, Gs3, A4, Ab4, As4, B4, Bb4, C4; // Implement viewDidLoad to do additional setup after loading the view, typically from a nib. - (void)viewDidLoad { NSString *path = [[NSBundle mainBundle] pathForResource:@"3C" ofType:@"mp3"]; NSLog(@"path: %@", path); NSURL *file = [[NSURL alloc] initFileURLWithPath:path]; AVAudioPlayer *p = [[AVAudioPlayer alloc] initWithContentsOfURL:file error:nil]; [file release]; self.player = p; [p release]; [player prepareToPlay]; [player setDelegate:self]; [super viewDidLoad]; } - (IBAction) playNote { [self.player play]; } Now, with the above I have two issues: First, the NSLog reports NULL and crashes when trying to play the file. I have added the mp3's to the resources folder and they have been copied and not just linked. They are not in an subfolder under the resources folder. Secondly, how can I set it up so that when say button C3 is pressed, it plays C3.mp3 and F3 plays F3.mp3 without writing duplicate lines of code for each different button? playNote should be like NSString *path = [[NSBundle mainBundle] pathForResource:nameOfButton ofType:@"mp3"]; instead of defining it specifically (@"C3"). Is there a better way of doing this and why does the *path report NULL and crash when I load the app? I'm pretty sure it's something as simple as adding additional variable inputs to - (IBAction) playNote:buttonName and putting all the code to call AVAudioPlayer in the playNote function but I'm unsure of the code to do this.

• c# opennetCF background worker - e.result gives a ObjectDisposedException

  - by ikky

  Hi! I'm new working with background worker in C#. Here is a class, and under it, you will find the instansiation of it, and under there i will define my problem for you: I have the class Drawing: class Drawing { BackgroundWorker bgWorker; ProgressBar progressBar; Panel panelHolder; public Drawing(ref ProgressBar pgbar, ref Panel panelBig) // Progressbar and panelBig as reference { this.panelHolder = panelBig; this.progressBar = pgbar; bgWorker = new BackgroundWorker(); bgWorker.WorkerReportsProgress = true; bgWorker.WorkerSupportsCancellation = true; bgWorker.DoWork += new OpenNETCF.ComponentModel.DoWorkEventHandler(this.bgWorker_DoWork); bgWorker.RunWorkerCompleted += new OpenNETCF.ComponentModel.RunWorkerCompletedEventHandler(this.bgWorker_RunWorkerCompleted); bgWorker.ProgressChanged += new OpenNETCF.ComponentModel.ProgressChangedEventHandler(this.bgWorker_ProgressChanged); } public void createDrawing() { bgWorker.RunWorkerAsync(); } private void bgWorker_DoWork(object sender, DoWorkEventArgs e) { Panel panelContainer = new Panel(); // Adding panels to the panelContainer for(i=0; i<100; i++) { Panel panelSubpanel = new Panel(); // Setting size, color, name etc.... panelContainer.Controls.Add(panelSubpanel); // Adding the subpanel to the panelContainer //Report the progress bgWorker.ReportProgress(0, i); // Reporting number of panels loaded } e.Result = imagePanel; // Send the result(a panel with lots of subpanels) as an argument } private void bgWorker_ProgressChanged(object sender, ProgressChangedEventArgs e) { this.progressBar.Value = (int)e.UserState; this.progressBar.Update(); } private void bgWorker_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e) { if (e.Error == null) { this.panelHolder = (Panel)e.Result; } else { MessageBox.Show("An error occured, please try again"); } } } Instansiating an object of this class: public partial class Draw: Form { public Draw() { ProgressBar progressBarLoading = new ProgressBar(); // Set lots of properties on progressBarLoading Panel panelBigPanelContainer = new Panel(); Drawing drawer = new Drawing(ref progressBarLoading, ref panelBigPanelContainer); drawer.createDrawing(); // this makes the object start a new thread, loading all the panels into a panel container, while also sending the progress to this progressbar. } } Here is my problem: In the private void bgWorker_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e) i don't get the e.Result as it should be. When i debug and look at the e.Result, the panel's properties have this exception message: '((System.Windows.Forms.Control)(e.Result)).ClientSize' threw an exception of type 'System.ObjectDisposedException' So the object gets disposed, but "why" is my question, and how can i fix this? I hope someone will answer me, this is making me crazy. Another question i have: Is it allowed to use "ref" with arguments? is it bad programming? Thanks in advance. I have also written how i understand the Background worker below here: This is what i think is the "rules" for background workers: bgWorker.RunWorkerAsync(); => starts a new thread. bgWorker_DoWork cannot reach the main thread without delegates - private void bgWorker_DoWork(object sender, DoWorkEventArgs e) { // The work happens here, this is a thread that is not reachable by the main thread e.Result => This is an argument which can be reached by bgWorker_RunWorkerCompleted() bgWorker.ReportProgress(progressVar); => Reports the progress to the bgWorker_ProgressChanged() } - private void bgWorker_ProgressChanged(object sender, ProgressChangedEventArgs e) { // I get the progress here, and can do stuff to the main thread from here (e.g update a control) this.ProgressBar.Value = e.ProgressPercentage; } - private void bgWorker_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e) { // This is where the thread is completed. // Here i can get e.Result from the bgWorker thread // From here i can reach controls in my main thread, and use e.Result in my main thread if (e.Error == null) { this.panelTileHolder = (Panel)e.Result; } else { MessageBox.Show("There was an error"); } }

• heimdal kerberos in openldap issue

  - by Brian

  I think I posted this on the wrong 'sister site', so here it is. I'm having a bit of trouble getting Kerberos (Heimdal version) to work nicely with OpenLDAP. The kerberos database is being stored in LDAP itself. The KDC uses SASL EXTERNAL authentication as root to access the container ou.

• Refresh QTextEdit in PyQt

  - by Mark Underwood

  Hi all, Im writing a PyQt app that takes some input in one widget, and then processes some text files. What ive got at the moment is when the user clicks the "process" button a seperate window with a QTextEdit in it pops up, and ouputs some logging messages. On Mac OS X this window is refreshed automatically and you cna see the process. On Windows, the window reports (Not Responding) and then once all the proccessing is done, the log output is shown. Im assuming I need to refresh the window after each write into the log, and ive had a look around at using a timer. etc, but havnt had much luck in getting it working. Below is the source code. It has two files, GUI.py which does all the GUI stuff and MOVtoMXF that does all the processing.

• Constant Memory Leak in SpeechSynthesizer

  - by DudeFX

  I have developed a project which I would like to release which uses c#, WPF and the System.Speech.Synthesizer object. The issue preventing the release of this project is that whenever SpeakAsync is called it leaves a memory leak that grows to the point of eventual failure. I believe I have cleaned up properly after using this object, but cannot find a cure. I have run the program through Ants Memory Profiler and it reports that WAVEHDR and WaveHeader is growing with each call. I have created a sample project to try to pinpoint the cause, but am still at a loss. Any help would be appreciated. The project uses VS2008 and is a c# WPF project that targets .NET 3.5 and Any CPU. You need to manually add a reference to System.Speech. Here is the Code: <Window x:Class="SpeechTest.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" Height="300" Width="300"> <Grid> <StackPanel Orientation="Vertical"> <Button Content="Start Speaking" Click="Start_Click" Margin="10" /> <Button Content="Stop Speaking" Click="Stop_Click" Margin="10" /> <Button Content="Exit" Click="Exit_Click" Margin="10"/> </StackPanel> </Grid> // Start of code behind using System; using System.Windows; using System.Speech.Synthesis; namespace SpeechTest { public partial class Window1 : Window { // speak setting private bool speakingOn = false; private int curLine = 0; private string [] speakLines = { "I am wondering", "Why whenever Speech is called", "A memory leak occurs", "If you run this long enough", "It will eventually crash", "Any help would be appreciated" }; public Window1() { InitializeComponent(); } private void Start_Click(object sender, RoutedEventArgs e) { speakingOn = true; SpeakLine(); } private void Stop_Click(object sender, RoutedEventArgs e) { speakingOn = false; } private void Exit_Click(object sender, RoutedEventArgs e) { App.Current.Shutdown(); } private void SpeakLine() { if (speakingOn) { // Create our speak object SpeechSynthesizer spk = new SpeechSynthesizer(); spk.SpeakCompleted += new EventHandler(spk_Completed); // Speak the line spk.SpeakAsync(speakLines[curLine]); } } public void spk_Completed(object sender, SpeakCompletedEventArgs e) { if (sender is SpeechSynthesizer) { // get access to our Speech object SpeechSynthesizer spk = (SpeechSynthesizer)sender; // Clean up after speaking (thinking the event handler is causing the memory leak) spk.SpeakCompleted -= new EventHandler(spk_Completed); // Dispose the speech object spk.Dispose(); // bump it curLine++; // check validity if (curLine = speakLines.Length) { // back to the beginning curLine = 0; } // Speak line SpeakLine(); } } } } I run this program on Windows 7 64 bit and it will run and eventually halt when attempting to create a new SpeechSynthesizer object. When run on Windows Vista 64 bit the memory will grow from a starting point of 34k to so far about 400k and growing. Can anyone see anything in the code that might be causing this, or is this an issue with the Speech object itself. Any help would be appreciated.

• Load-balancing between a Procurve switch and a server

  - by vlad

  Hello I've been searching around the web for this problem i've been having. It's similar in a way to this question: How exactly & specifically does layer 3 LACP destination address hashing work? My setup is as follows: I have a central switch, a Procurve 2510G-24, image version Y.11.16. It's the center of a star topology, there are four switches connected to it via a single gigabit link. Those switches service the users. On the central switch, I have a server with two gigabit interfaces that I want to bond together in order to achieve higher throughput, and two other servers that have single gigabit connections to the switch. The topology looks as follows: sw1 sw2 sw3 sw4 | | | | --------------------- | sw0 | --------------------- || | | srv1 srv2 srv3 The servers were running FreeBSD 8.1. On srv1 I set up a lagg interface using the lacp protocol, and on the switch I set up a trunk for the two ports using lacp as well. The switch showed that the server was a lacp partner, I could ping the server from another computer, and the server could ping other computers. If I unplugged one of the cables, the connection would keep working, so everything looked fine. Until I tested throughput. There was only one link used between srv1 and sw0. All testing was conducted with iperf, and load distribution was checked with systat -ifstat. I was looking to test the load balancing for both receive and send operations, as I want this server to be a file server. There were therefore two scenarios: iperf -s on srv1 and iperf -c on the other servers iperf -s on the other servers and iperf -c on srv1 connected to all the other servers. Every time only one link was used. If one cable was unplugged, the connections would keep going. However, once the cable was plugged back in, the load was not distributed. Each and every server is able to fill the gigabit link. In one-to-one test scenarios, iperf was reporting around 940Mbps. The CPU usage was around 20%, which means that the servers could withstand a doubling of the throughput. srv1 is a dell poweredge sc1425 with onboard intel 82541GI nics (em driver on freebsd). After troubleshooting a previous problem with vlan tagging on top of a lagg interface, it turned out that the em could not support this. So I figured that maybe something else is wrong with the em drivers and / or lagg stack, so I started up backtrack 4r2 on this same server. So srv1 now uses linux kernel 2.6.35.8. I set up a bonding interface bond0. The kernel module was loaded with option mode=4 in order to get lacp. The switch was happy with the link, I could ping to and from the server. I could even put vlans on top of the bonding interface. However, only half the problem was solved: if I used srv1 as a client to the other servers, iperf was reporting around 940Mbps for each connection, and bwm-ng showed, of course, a nice distribution of the load between the two nics; if I run the iperf server on srv1 and tried to connect with the other servers, there was no load balancing. I thought that maybe I was out of luck and the hashes for the two mac addresses of the clients were the same, so I brought in two new servers and tested with the four of them at the same time, and still nothing changed. I tried disabling and reenabling one of the links, and all that happened was the traffic switched from one link to the other and back to the first again. I also tried setting the trunk to "plain trunk mode" on the switch, and experimented with other bonding modes (roundrobin, xor, alb, tlb) but I never saw any traffic distribution. One interesting thing, though: one of the four switches is a Cisco 2950, image version 12.1(22)EA7. It has 48 10/100 ports and 2 gigabit uplinks. I have a server (call it srv4) with a 4 channel trunk connected to it (4x100), FreeBSD 8.0 release. The switch is connected to sw0 via gigabit. If I set up an iperf server on one of the servers connected to sw0 and a client on srv4, ALL 4 links are used, and iperf reports around 330Mbps. systat -ifstat shows all four interfaces are used. The cisco port-channel uses src-mac to balance the load. The HP should use both the source and destination according to the manual, so it should work as well. Could this mean there is some bug in the HP firmware? Am I doing something wrong?

• Debian apt dependency mismatch (libc6)

  Earlier, I tried to install package via apt-get (cython), but it failed with the Errors were encountered while processing: message, and since then, apt is refusing to install anything. apt-get check output below: root@dix:~# apt-get check Reading package lists...

• How to disable Mac OS X from using swap when there still is "Inactive" memory?

  - by Motin

  A common phenomena in my day to day usage (and several other's according to various posts throughout the internet) of OS X, the system seems to become slow whenever there is no more "Free" memory available. Supposedly, this is due to swapping, since heavy disk activity is apparent and that vm_stat reports many pageouts. (Correct me from wrong) However, the amount of "Inactive" ram is typically around 12.5%-25% of all available memory (^1.) when swapping starts/occurs/ends. According to http://support.apple.com/kb/ht1342 : Inactive memory This information in memory is not actively being used, but was recently used. For example, if you've been using Mail and then quit it, the RAM that Mail was using is marked as Inactive memory. This Inactive memory is available for use by another application, just like Free memory. However, if you open Mail before its Inactive memory is used by a different application, Mail will open quicker because its Inactive memory is converted to Active memory, instead of loading Mail from the slower hard disk. And according to http://developer.apple.com/library/mac/#documentation/Performance/Conceptual/ManagingMemory/Articles/AboutMemory.html : The inactive list contains pages that are currently resident in physical memory but have not been accessed recently. These pages contain valid data but may be released from memory at any time. So, basically: When a program has quit, it's memory becomes marked as Inactive and should be claimable at any time. Still, OS X will prefer to start swapping out memory to the Swap file instead of just claiming this memory, whenever the "Free" memory gets to low. Why? What is the advantage of this behavior over, say, instantly releasing Inactive memory and not even touch the swap file? Some sources (^2.) indicate that OS X would page out the "Inactive" memory to swap before releasing it, but that doesn't make sense now does it if the memory may be released from memory at any time? Swapping is expensive, releasing is cheap, right? Can this behavior be changed using some preference or known hack? (Preferably one that doesn't include disabling swap/dynamic_pager altogether and restarting...) I do appreciate the purge command, as well as the concept of Repairing disk permissions to force some Free memory, but those are ways to painfully force more Free memory than to actually fixing the swap/release decision logic... Btw a similar question was asked here: http://forums.macnn.com/90/mac-os-x/434650/why-does-os-x-swap-when/ and here: http://hintsforums.macworld.com/showthread.php?t=87688 but even though the OPs re-asked the core question, none of the replies addresses an answer to it... ^1. UPDATE 17-mar-2012 Since I first posted this question, I have gone from 4gb to 8gb of installed ram, and the problem remains. The amount of "Inactive" ram was 0.5gb-1.0gb before and is now typically around 1.0-2.0GB when swapping starts/occurs/ends, ie it seems that around 12.5%-25% of the ram is preserved as Inactive by osx kernel logic. ^2. For instance http://apple.stackexchange.com/questions/4288/what-does-it-mean-if-i-have-lots-of-inactive-memory-at-the-end-of-a-work-day : Once all your memory is used (free memory is 0), the OS will write out inactive memory to the swapfile to make more room in active memory. UPDATE 17-mar-2012 Here is a round-up of the methods that have been suggested to help so far: The purge command "Used to approximate initial boot conditions with a cold disk buffer cache for performance analysis. It does not affect anonymous memory that has been allocated through malloc, vm_allocate, etc". This is useful to prevent osx to swap-out the disk cache (which is ridiculous that osx actually does so in the first place), but with the downside that the disk cache is released, meaning that if the disk cache was not about to be swapped out, one would simply end up with a cold disk buffer cache, probably affecting performance negatively. The FreeMemory app and/or Repairing disk permissions to force some Free memory Doesn't help releasing any memory, only moving some gigabytes of memory contents from ram to the hd. In the end, this causes lots of swap-ins when I attempt to use the applications that were open while freeing memory, as a lot of its vm is now on swap. Speeding up swap-allocation using dynamicpagerwrapper Seems a good thing to do in order to speed up swap-usage, but does not address the problem of osx swapping in the first place while there is still inactive memory. Disabling swap by disabling dynamicpager and restarting This will force osx not to use swap to the price of the system hanging when all memory is used. Not a viable alternative... Disabling swap using a hacked dynamicpager Similar to disabling dynamicpager above, some excerpts from the comments to the blog post indicate that this is not a viable solution: "The Inactive Memory is high as usual". "when your system is running out of memory, the whole os hangs...", "if you consume the whole amount of memory of the mac, the machine will likely hang" To sum up, I am still unaware of a way of disabling Mac OS X from using swap when there still is "Inactive" memory. If it isn't possible, maybe at least there is an explanation somewhere of why osx prefers to swap out memory that may be released from memory at any time?

• How to overcome shortcomings in reporting from EAV database?

  - by David Archer

  The major shortcomings with Entity-Attribute-Value database designs in SQL all seem to be related to being able to query and report on the data efficiently and quickly. Most of the information I read on the subject warn against implementing EAV due to these problems and the commonality of querying/reporting for almost all applications. I am currently designing a system where almost all the fields necessary for data storage are not known at design/compile time and are defined by the end-user of the system. EAV seems like a good fit for this requirement but due to the problems I've read about, I am hesitant in implementing it as there are also some pretty heavy reporting requirements for this system as well. I think I've come up with a way around this but would like to pose the question to the SO community. Given that typical normalized database (OLTP) still isn't always the best option for running reports, a good practice seems to be having a "reporting" database (OLAP) where the data from the normalized database is copied to, indexed extensively, and possibly denormalized for easier querying. Could the same idea be used to work around the shortcomings of an EAV design? The main downside I see are the increased complexity of transferring the data from the EAV database to reporting as you may end up having to alter the tables in the reporting database as new fields are defined in the EAV database. But that is hardly impossible and seems to be an acceptable tradeoff for the increased flexibility given by the EAV design. This downside also exists if I use a non-SQL data store (i.e. CouchDB or similar) for the main data storage since all the standard reporting tools are expecting a SQL backend to query against. Do the issues with EAV systems mostly go away if you have a seperate reporting database for querying? EDIT: Thanks for the comments so far. One of the important things about the system I'm working on it that I'm really only talking about using EAV for one of the entities, not everything in the system. The whole gist of the system is to be able to pull data from multiple disparate sources that are not known ahead of time and crunch the data to come up with some "best known" data about a particular entity. So every "field" I'm dealing with is multi-valued and I'm also required to track history for each. The normalized design for this ends up being 1 table per field which makes querying it kind of painful anyway. Here are the table schemas and sample data I'm looking at (obviously changed from what I'm working on but I think it illustrates the point well): EAV Tables Person ------------------- - Id - Name - ------------------- - 123 - Joe Smith - ------------------- Person_Value ------------------------------------------------------------------- - PersonId - Source - Field - Value - EffectiveDate - ------------------------------------------------------------------- - 123 - CIA - HomeAddress - 123 Cherry Ln - 2010-03-26 - - 123 - DMV - HomeAddress - 561 Stoney Rd - 2010-02-15 - - 123 - FBI - HomeAddress - 676 Lancas Dr - 2010-03-01 - ------------------------------------------------------------------- Reporting Table Person_Denormalized ---------------------------------------------------------------------------------------- - Id - Name - HomeAddress - HomeAddress_Confidence - HomeAddress_EffectiveDate - ---------------------------------------------------------------------------------------- - 123 - Joe Smith - 123 Cherry Ln - 0.713 - 2010-03-26 - ---------------------------------------------------------------------------------------- Normalized Design Person ------------------- - Id - Name - ------------------- - 123 - Joe Smith - ------------------- Person_HomeAddress ------------------------------------------------------ - PersonId - Source - Value - Effective Date - ------------------------------------------------------ - 123 - CIA - 123 Cherry Ln - 2010-03-26 - - 123 - DMV - 561 Stoney Rd - 2010-02-15 - - 123 - FBI - 676 Lancas Dr - 2010-03-01 - ------------------------------------------------------ The "Confidence" field here is generated using logic that cannot be expressed easily (if at all) using SQL so my most common operation besides inserting new values will be pulling ALL data about a person for all fields so I can generate the record for the reporting table. This is actually easier in the EAV model as I can do a single query. In the normalized design, I end up having to do 1 query per field to avoid a massive cartesian product from joining them all together.

• Java 7 update 6 installation fails on Windows 7 when Chrome is default browser

  - by ali1234

  I am configuring a brand new Lenovo U410 system with Windows 7 Home Premium for a user. I received the system direct from the shop. As part of the configuration I installed Java using the online installer. This worked correctly. Later, due to a mistake I made, I needed to restore the system to factory default. The factory default FORMATS C:\ and puts back (supposedly) the exact factory configuration. However, after doing this, I was no longer able to install Java successfully using the same method I used before. Now, whenever I attempt to use the online Java installer, the following happens. First of all, a window always appears "Welcome to Java", "Downloading Java Installer...". After short time this window disappears and then one of three things happens: The very first time I do this after doing a factory reset, I get a Windows error report, which contains this information: Application Name: JavaSetup7u5.exe Application Version: 7.0.50.6 Application Timestamp: 4feacd84 Fault Module Name: JavaIC.dll Fault Module Version: 9.9.9.9 Fault Module Timestamp: 4f2343d6 Exception Offset: 000052cb Exception Code: c0000417 Exception Data: 00000000 OS Version: 6.1.7600.2.0.0.768.3 Locale ID: 1033 Additional Information 1: 773c Additional Information 2: 773cd78cf06816f8246f359fa270f3bb Additional Information 3: f51a Additional Information 4: f51aaea7d22f36fa9e3a626b5a5cd1c3 2. Subsequent runs produce either this error message: "Error: Java(TM) installer - Downloaded file C:\Users\\AppData\Local\Temp\fx-runtime.exe is corrupt." or Nothing happens at all. I Believe this is a red herring. Running the installer again causes a different error because the files were downloaded and the installer crashed before it could clean up. This isn't the actual problem, as when this happens the installer deletes the downloaded files, and then when you run it for the third time, it downloads everything again and does the javaic.dll crash. I suspect the downloader is appending to the existing files or something, causing the corruption. I have tried all of the above as Administrator and as a normal user. I have tried reseting the system to factory defaults several times. I have tried downloading with Chrome and Internet Explorer 9. I have tried uninstalling all anti-virus software and disabling the windows firewall entirely. The only thing which makes a difference is running the installer in Windows XP compatibility mode, which allows the installation to complete. I know I can workaround this error by using the offline installer so please don't post that as an answer. I am looking for an explanation of the root cause. Additionally, if I use the offline installer, the updater does not work. The updater also does not work if I install in XP mode. The updater fails because it works by just downloading the newest online setup and running it. Also remember that the installers are digitally signed. The signitures verify correctly so there is no way in hell that this is caused by corrupted downloads. Some theories I have: The Java setup files on java.com actually changed in between the first successful install and my later attempts. Seems unlikely as none of the version numbers have changed. However, I have seen a couple of reports of this error which showed up in the past 24 hours. This looks like the most likely explanation right now: http://www.oracle.com/us/corporate/press/1735645 - Oracle released 7 update 6 two days ago. Careful inspection of the installers reveal that they are in fact attempting to download .6, not .5 as the download page claims. Not actually correct. Only the update tool tries to install 7u6. The online installer still tries 7u5. However, 7u6 being released two days ago is too much of a coincidence to ignore. Update: The 7u6 online installer is available from Oracle technetwork. It crashes in exactly the same way. The factory reset software uses GMT-8 and I am on GMT-1. As a result, after factory reset, any software which cares to check would think that the system was restored 7 hours in the future, due to Window's awful policy of storing local time in the system clock. This could be confusing a certificate check or similar. Update: I discovered that this does cause Windows Update to fail. The workaround, setting the clock back before starting factory reset, does not enable Java to install correctly. The factory reset image isn't really the same as what is installed in the main partition when you buy the system. Naughty Lenovo. The installer appears to crash while installing or displaying something to do with the Ask.com toolbar. That seems to be what javaic.dll does. Microsoft Tuesday was the 14th. Some update in that could be causing this. However, I'm factory reseting the machine every time, so unless the patches get slipstreamed into the recovery image, or there is some mechanism by which they get silently installed even if updates are disabled, then I don't see how this can be the cause. Major breakthrough: The default browser on Lenovo systems is Google Chrome. I noticed that the JavaIC.dll "sponsor check" actually does a check on your default browser in order to decide which sponsor ad to display. Normally that would get you the Ask toolbar on IE9. But that toolbar doesn't work on Chrome, and so the installer tries to display a different ad. The different ad is what causes the crash. Changing the default browser to IE9 allows the installer to run correctly. So this looks like a genuine bug in the sponsor ad code in the installer, caused by a combination of Google Chrome default browser and not being in the US. (Installer also checks your location using IP geolocation service and displays different ads based on that.)

• NSMutableString leaks on append or replaceOccurrencesOfString

  - by John

  Hello Folks, I know similar questions have been asked time and time again but I ask that you please bear with me as I cannot seem to find an answer that helps. My application has leaks that are driving me out of my mind. Actually, they are not reported as leaks using Leaks, but my net bytes in ObjectAlloc goes up and up and up and never stops, eventually leading to a crash if it goes on long enough (not very long). The problem occurs with NSMutableStrings. I think there is either something fundamental I don't understand about them, or I am facing another problem that I am having difficulty tracking down but keeps hiding behind the NSMutableStrings. Specifically, I am noticing that whenever I append to or perform a replace on a NSMutableString, ObjectAlloc reports what appear to be mismatches in malloc/frees behind the scene when resizing the NSMutableString. I'm sorry to say this is the second time I'm facing this problem - the first time I messed around for hours and hours and finally the problem went away (magic!) but I don't really know why. When I look at the code below (and believe me, I've stared at it for hours) I cannot see the problem. I look at the code and think to myself that I should be fine because I'm releasing the only object for which I am responsible (aString) and that NSMutableString should be taking care of cleaning up after any resizing it does. In the second example, just so you know in case it helps, the string being passed in comes from an ASIHTTPRequest object (it's the responseString) and I don't do anything at all with it. It's being called simply like so ([self DoStuff2:[request responseString]]) and I don't free the request myself either (I'm using a ASINetworkQueue and I assume that the requests are destroyed for me (I tried and caused errors because the request was already being release somewhere else). Also, I know it shouldn't do anything, but I even tried wrapping the code in autorelease pools, which of course did nothing. I should mention that this code is being run inside of an NSOperation. I thought that perhaps I am experiencing problems because NSOperations should create an autorelease pool for themselves, but I've tried that to no avail. Not related to NSMutableString, but I find I also have similar problems using the NSString componentsSeparatedByString method. Sometimes the memory used by the array that gets the separated components is never released. Hmmm...strings in general seem to be somewhat problematic for me it seems. I would appreciate ANY help anyone can provide. If you require more info, I'll be glad to add it. I do promise you that I've struggled with this (and other problems) for weeks and every problem I encounter I research hard and long until I find a solution - this is not an idle request, but a true cry for help! I've written so much code and now I'm trying to seal some small leaks etc and I notice this problem. Honestly, I cannot believe how memory management in Objective C can stump me so at times...I've read Apple's memory mgmt docs many times and I thought I thoroughly understood it and I try to be diligent about releasing objects I own, but sometimes I find myself wondering if I truly understand...I would like to put this to bed once and make sure I understand all this fully - to have this sort of question/problem after writing thousands of lines of code is more than a little scary/embarrassing/annoying. So again, if anybody has any insight, I'd be grateful. Thanks for your time and efforts. -(void)DoStuff { NSString *aString [ [[NSString alloc] initWithFormat:@"text %@ more text", self.strVariable]; [self.someMutableStringVar replaceOccurrencesOfString:@"replace" withString:aString options:NSCaseInsensitiveSearch range:NSMakeRange(0, [self.someMutableStringVar length])]; [aString release]; } -(void)DoStuff2:(NSString *)aString { [self.someMutableStringVar appendString:aString]; }

• Server Memory with Magento

  - by Mohamed Elgharabawy

  I have a cloud server with the following specifications: 2vCPUs 4G RAM 160GB Disk Space Network 400Mb/s System Image: Ubuntu 12.04 LTS I am only running Magento CE 1.7.0.2 on this server. Nothing else. Usually, the server has a loading time of 4-5 seconds. Recently, this has dropped to over 30 seconds and sometimes the server just goes away and I get HTTP error reports to my email stating that HTTP requests took more than 20000ms.

If I don't need to upgrade and my configuration is not correct, how do I optimize it?

• Why do UInt16 arrays seem to add faster than int arrays?

  - by scraimer

  It seems that C# is faster at adding two arrays of UInt16[] than it is at adding two arrays of int[]. This makes no sense to me, since I would have assumed the arrays would be word-aligned, and thus int[] would require less work from the CPU, no? I ran the test-code below, and got the following results: Int for 1000 took 9896625613 tick (4227 msec) UInt16 for 1000 took 6297688551 tick (2689 msec) The test code does the following: Creates two arrays named a and b, once. Fills them with random data, once. Starts a stopwatch. Adds a and b, item-by-item. This is done 1000 times. Stops the stopwatch. Reports how long it took. This is done for int[] a, b and for UInt16 a,b. And every time I run the code, the tests for the UInt16 arrays take 30%-50% less time than the int arrays. Can you explain this to me? Here's the code, if you want to try if for yourself: public static UInt16[] GenerateRandomDataUInt16(int length) { UInt16[] noise = new UInt16[length]; Random random = new Random((int)DateTime.Now.Ticks); for (int i = 0; i < length; ++i) { noise[i] = (UInt16)random.Next(); } return noise; } public static int[] GenerateRandomDataInt(int length) { int[] noise = new int[length]; Random random = new Random((int)DateTime.Now.Ticks); for (int i = 0; i < length; ++i) { noise[i] = (int)random.Next(); } return noise; } public static int[] AddInt(int[] a, int[] b) { int len = a.Length; int[] result = new int[len]; for (int i = 0; i < len; ++i) { result[i] = (int)(a[i] + b[i]); } return result; } public static UInt16[] AddUInt16(UInt16[] a, UInt16[] b) { int len = a.Length; UInt16[] result = new UInt16[len]; for (int i = 0; i < len; ++i) { result[i] = (ushort)(a[i] + b[i]); } return result; } public static void Main() { int count = 1000; int len = 128 * 6000; int[] aInt = GenerateRandomDataInt(len); int[] bInt = GenerateRandomDataInt(len); Stopwatch s = new Stopwatch(); s.Start(); for (int i=0; i<count; ++i) { int[] resultInt = AddInt(aInt, bInt); } s.Stop(); Console.WriteLine("Int for " + count + " took " + s.ElapsedTicks + " tick (" + s.ElapsedMilliseconds + " msec)"); UInt16[] aUInt16 = GenerateRandomDataUInt16(len); UInt16[] bUInt16 = GenerateRandomDataUInt16(len); s = new Stopwatch(); s.Start(); for (int i=0; i<count; ++i) { UInt16[] resultUInt16 = AddUInt16(aUInt16, bUInt16); } s.Stop(); Console.WriteLine("UInt16 for " + count + " took " + s.ElapsedTicks + " tick (" + s.ElapsedMilliseconds + " msec)"); }
