  • Persisting and applying Linq Query to collection

    - by MattiasK
    I have a scenario where I would want a plugin to construct a LINQ (to objects) query, send it across an appdomain and then apply and run it against a collection of my choosing Is it possible, how? If not, perhaps I could send a whole method (interface) across the appdomain and run it against the data on the appside? The main thing is that I want the data to reside in the CurrentDomain and the logic for operating on it in the plugin so I don't have to send the data across the boundary...

    - by BahaiResearch.com
    (I'm coming from an iPhone dev world. ) In Android do we need to worry what OS version we compile against? In the iPhone world I would usually target a release that's at least 6 months old to limit the number of issues with installing on iPhones with old OSs. What strategy should I use when choosing what to compile against on the Android?

  • The Evolution of Television and Home Entertainment

    - by Bill Evjen
    This is a group that is focused on entertainment in the aviation industry. I am attending their conference for the first time as it relates to my job at Swank Motion Pictures and what we do for our various markets. I will post my notes here. The Evolution of Television and Home Entertainment by Patrick Cosson, Veebeam TV has been the center of living rooms for sometime. Conversations and culture evolve around the TV. The way we consume this content has dramatically been changing. After TV, we had the MTV revolution of TV. It has created shorter attention spans, it made us more materialistic, narcissistic, and not easily impressed. Then we came to the Internet. The amount of content has expanded. It contains a ton of user-generated content, provides filtering, organization, distribution. We now have a problem. We are in the age of digital excess. We can access whatever we want. In conjunction with this – we are moving. The challenge we have now is curation. The trends  we see: rapid shift from scheduled to on demand consumption. A move to Internet protocols from cable Rapid fragmentation of media a transition from the TV set to a variety of screens Social connections bring mediators and amplifiers. TiVo – the shift to on demand It is because of a time-crunch Provides personal experiences Once old consumption habits are changed, there is no way back! Experiences are that people are loading up content and then bringing it with them on planes, to hotels, etc. Rapid fragmentation of media sources Many new professional content sources and channels, the rise of digital distribution, and the rise of user-generated content contribute to the wealth of content sources and abundant choice. Netflix, BBC iPlayer, hulu, Pandora, iTunes, Amazon Video, Vudu, Voddler, Spotify (these companies didn’t exist 5 years ago). People now expect this kind of consumption. People are now thinking how to deliver all these tools. Transition from the TV set to multi-screens The TV screen has traditionally been the dominant consumption screen for TV and video. Now the PC, game consoles, and various mobile devices are rapidly becoming common video devices. Multi-screens are now the norm. Social connections becoming key mediators What increasingly funnels traffic on the web, social networking enablers, will become an integral part of the discovery, consumption and sharing model for Television. The revolution will be broadcasted on Facebook and Twitter. There is business disruption There are a lot of new entrants Rapid internationalization Increasing competition from existing media players A fragmenting audience base Web browser Freedom to access any site The fight over the walled garden Most devices are not powerful enough to support a full browser PC will always be present in the living room Wireless link between PC and TV Output 1080p, plays anything, secure Key players and their challenges Services Internet media is increasingly interconnected to social media and publicly shared UGC Content delivery moving to IPTV Rights management issues are creating silos and hindering a great user experience and growth Devices Devices are becoming people’s windows into all kinds of media from all kinds of sources There won’t be a consolidation of the device landscape, rather the opposite Finding the right niche makes the most sense. We are moving to an on demand world of streaming world. People want full access to anything.

  • How to Achieve OC4J RMI Load Balancing

    - by fip
    This is an old, Oracle SOA and OC4J 10G topic. In fact this is not even a SOA topic per se. Questions of RMI load balancing arise when you developed custom web applications accessing human tasks running off a remote SOA 10G cluster. Having returned from a customer who faced challenges with OC4J RMI load balancing, I felt there is still some confusions in the field how OC4J RMI load balancing work. Hence I decide to dust off an old tech note that I wrote a few years back and share it with the general public. Here is the tech note: Overview A typical use case in Oracle SOA is that you are building web based, custom human tasks UI that will interact with the task services housed in a remote BPEL 10G cluster. Or, in a more generic way, you are just building a web based application in Java that needs to interact with the EJBs in a remote OC4J cluster. In either case, you are talking to an OC4J cluster as RMI client. Then immediately you must ask yourself the following questions: 1. How do I make sure that the web application, as an RMI client, even distribute its load against all the nodes in the remote OC4J cluster? 2. How do I make sure that the web application, as an RMI client, is resilient to the node failures in the remote OC4J cluster, so that in the unlikely case when one of the remote OC4J nodes fail, my web application will continue to function? That is the topic of how to achieve load balancing with OC4J RMI client. Solutions You need to configure and code RMI load balancing in two places: 1. Provider URL can be specified with a comma separated list of URLs, so that the initial lookup will land to one of the available URLs. 2. Choose a proper value for the oracle.j2ee.rmi.loadBalance property, which, along side with the PROVIDER_URL property, is one of the JNDI properties passed to the JNDI lookup.(http://docs.oracle.com/cd/B31017_01/web.1013/b28958/rmi.htm#BABDGFBI) More details below: About the PROVIDER_URL The JNDI property java.name.provider.url's job is, when the client looks up for a new context at the very first time in the client session, to provide a list of RMI context The value of the JNDI property java.name.provider.url goes by the format of a single URL, or a comma separate list of URLs. A single URL. For example: opmn:ormi://host1:6003:oc4j_instance1/appName1 A comma separated list of multiple URLs. For examples:  opmn:ormi://host1:6003:oc4j_instanc1/appName, opmn:ormi://host2:6003:oc4j_instance1/appName, opmn:ormi://host3:6003:oc4j_instance1/appName When the client looks up for a new Context the very first time in the client session, it sends a query against the OPMN referenced by the provider URL. The OPMN host and port specifies the destination of such query, and the OC4J instance name and appName are actually the “where clause” of the query. When the PROVIDER URL reference a single OPMN server Let's consider the case when the provider url only reference a single OPMN server of the destination cluster. In this case, that single OPMN server receives the query and returns a list of the qualified Contexts from all OC4Js within the cluster, even though there is a single OPMN server in the provider URL. A context represent a particular starting point at a particular server for subsequent object lookup. For example, if the URL is opmn:ormi://host1:6003:oc4j_instance1/appName, then, OPMN will return the following contexts: appName on oc4j_instance1 on host1 appName on oc4j_instance1 on host2, appName on oc4j_instance1 on host3,  (provided that host1, host2, host3 are all in the same cluster) Please note that One OPMN will be sufficient to find the list of all contexts from the entire cluster that satisfy the JNDI lookup query. You can do an experiment by shutting down appName on host1, and observe that OPMN on host1 will still be able to return you appname on host2 and appName on host3. When the PROVIDER URL reference a comma separated list of multiple OPMN servers When the JNDI propery java.naming.provider.url references a comma separated list of multiple URLs, the lookup will return the exact same things as with the single OPMN server: a list of qualified Contexts from the cluster. The purpose of having multiple OPMN servers is to provide high availability in the initial context creation, such that if OPMN at host1 is unavailable, client will try the lookup via OPMN on host2, and so on. After the initial lookup returns and cache a list of contexts, the JNDI URL(s) are no longer used in the same client session. That explains why removing the 3rd URL from the list of JNDI URLs will not stop the client from getting the EJB on the 3rd server. About the oracle.j2ee.rmi.loadBalance Property After the client acquires the list of contexts, it will cache it at the client side as “list of available RMI contexts”.  This list includes all the servers in the destination cluster. This list will stay in the cache until the client session (JVM) ends. The RMI load balancing against the destination cluster is happening at the client side, as the client is switching between the members of the list. Whether and how often the client will fresh the Context from the list of Context is based on the value of the  oracle.j2ee.rmi.loadBalance. The documentation at http://docs.oracle.com/cd/B31017_01/web.1013/b28958/rmi.htm#BABDGFBI list all the available values for the oracle.j2ee.rmi.loadBalance. Value Description client If specified, the client interacts with the OC4J process that was initially chosen at the first lookup for the entire conversation. context Used for a Web client (servlet or JSP) that will access EJBs in a clustered OC4J environment. If specified, a new Context object for a randomly-selected OC4J instance will be returned each time InitialContext() is invoked. lookup Used for a standalone client that will access EJBs in a clustered OC4J environment. If specified, a new Context object for a randomly-selected OC4J instance will be created each time the client calls Context.lookup(). Please note the regardless of the setting of oracle.j2ee.rmi.loadBalance property, the “refresh” only occurs at the client. The client can only choose from the "list of available context" that was returned and cached from the very first lookup. That is, the client will merely get a new Context object from the “list of available RMI contexts” from the cache at the client side. The client will NOT go to the OPMN server again to get the list. That also implies that if you are adding a node to the server cluster AFTER the client’s initial lookup, the client would not know it because neither the server nor the client will initiate a refresh of the “list of available servers” to reflect the new node. About High Availability (i.e. Resilience Against Node Failure of Remote OC4J Cluster) What we have discussed above is about load balancing. Let's also discuss high availability. This is how the High Availability works in RMI: when the client use the context but get an exception such as socket is closed, it knows that the server referenced by that Context is problematic and will try to get another unused Context from the “list of available contexts”. Again, this list is the list that was returned and cached at the very first lookup in the entire client session.

  • This Week in Geek History: Gmail Goes Public, Deep Blue Wins at Chess, and the Birth of Thomas Edison

    - by Jason Fitzpatrick
    Every week we bring you a snapshot of the week in Geek History. This week we’re taking a peek at the public release of Gmail, the first time a computer won against a chess champion, and the birth of prolific inventor Thomas Edison. Gmail Goes Public It’s hard to believe that Gmail has only been around for seven years and that for the first three years of its life it was invite only. In 2007 Gmail dropped the invite only requirement (although they would hold onto the “beta” tag for another two years) and opened its doors for anyone to grab a username @gmail. For what seemed like an entire epoch in internet history Gmail had the slickest web-based email around with constant innovations and features rolling out from Gmail Labs. Only in the last year or so have major overhauls at competitors like Hotmail and Yahoo! Mail brought other services up to speed. Can’t stand reading a Week in Geek History entry without a random fact? Here you go: gmail.com was originally owned by the Garfield franchise and ran a service that delivered Garfield comics to your email inbox. No, we’re not kidding. Deep Blue Proves Itself a Chess Master Deep Blue was a super computer constructed by IBM with the sole purpose of winning chess matches. In 2011 with the all seeing eye of Google and the amazing computational abilities of engines like Wolfram Alpha we simply take powerful computers immersed in our daily lives for granted. The 1996 match against reigning world chest champion Garry Kasparov where in Deep Blue held its own, but ultimately lost, in a  4-2 match shook a lot of people up. What did it mean if something that was considered such an elegant and quintessentially human endeavor such as chess was so easy for a machine? A series of upgrades helped Deep Blue outright win a match against Kasparov in 1997 (seen in the photo above). After the win Deep Blue was retired and disassembled. Parts of Deep Blue are housed in the National Museum of History and the Computer History Museum. Birth of Thomas Edison Thomas Alva Edison was one of the most prolific inventors in history and holds an astounding 1,093 US Patents. He is responsible for outright inventing or greatly refining major innovations in the history of world culture including the phonograph, the movie camera, the carbon microphone used in nearly every telephone well into the 1980s, batteries for electric cars (a notion we’d take over a century to take seriously), voting machines, and of course his enormous contribution to electric distribution systems. Despite the role of scientist and inventor being largely unglamorous, Thomas Edison and his tumultuous relationship with fellow inventor Nikola Tesla have been fodder for everything from books, to comics, to movies, and video games. Other Notable Moments from This Week in Geek History Although we only shine the spotlight on three interesting facts a week in our Geek History column, that doesn’t mean we don’t have space to highlight a few more in passing. This week in Geek History: 1971 – Apollo 14 returns to Earth after third Lunar mission. 1974 – Birth of Robot Chicken creator Seth Green. 1986 – Death of Dune creator Frank Herbert. Goodnight Dune. 1997 – Simpsons becomes longest running animated show on television. Have an interesting bit of geek trivia to share?

  • How do NTP Servers Manage to Stay so Accurate?

    - by Akemi Iwaya
    Many of us have had the occasional problem with our computers and other devices retaining accurate time settings, but a quick sync with an NTP server makes all well again. But if our own devices can lose accuracy, how do NTP servers manage to stay so accurate? Today’s Question & Answer session comes to us courtesy of SuperUser—a subdivision of Stack Exchange, a community-driven grouping of Q&A web sites. Photo courtesy of LEOL30 (Flickr). The Question SuperUser reader Frank Thornton wants to know how NTP servers are able to remain so accurate: I have noticed that on my servers and other machines, the clocks always drift so that they have to sync up to remain accurate. How do the NTP server clocks keep from drifting and always remain so accurate? How do the NTP servers manage to remain so accurate? The Answer SuperUser contributor Michael Kjorling has the answer for us: NTP servers rely on highly accurate clocks for precision timekeeping. A common time source for central NTP servers are atomic clocks, or GPS receivers (remember that GPS satellites have atomic clocks onboard). These clocks are defined as accurate since they provide a highly exact time reference. There is nothing magical about GPS or atomic clocks that make them tell you exactly what time it is. Because of how atomic clocks work, they are simply very good at, having once been told what time it is, keeping accurate time (since the second is defined in terms of atomic effects). In fact, it is worth noting that GPS time is distinct from the UTC that we are more used to seeing. These atomic clocks are in turn synchronized against International Atomic Time or TAI in order to not only accurately tell the passage of time, but also the time. Once you have an exact time on one system connected to a network like the Internet, it is a matter of protocol engineering enabling transfer of precise times between hosts over an unreliable network. In this regard a Stratum 2 (or farther from the actual time source) NTP server is no different from your desktop system syncing against a set of NTP servers. By the time you have a few accurate times (as obtained from NTP servers or elsewhere) and know the rate of advancement of your local clock (which is easy to determine), you can calculate your local clock’s drift rate relative to the “believed accurate” passage of time. Once locked in, this value can then be used to continuously adjust the local clock to make it report values very close to the accurate passage of time, even if the local real-time clock itself is highly inaccurate. As long as your local clock is not highly erratic, this should allow keeping accurate time for some time even if your upstream time source becomes unavailable for any reason. Some NTP client implementations (probably most ntpd daemon or system service implementations) do this, and others (like ntpd’s companion ntpdate which simply sets the clock once) do not. This is commonly referred to as a drift file because it persistently stores a measure of clock drift, but strictly speaking it does not have to be stored as a specific file on disk. In NTP, Stratum 0 is by definition an accurate time source. Stratum 1 is a system that uses a Stratum 0 time source as its time source (and is thus slightly less accurate than the Stratum 0 time source). Stratum 2 again is slightly less accurate than Stratum 1 because it is syncing its time against the Stratum 1 source and so on. In practice, this loss of accuracy is so small that it is completely negligible in all but the most extreme of cases. Have something to add to the explanation? Sound off in the comments.

  • GCC 4.2.1 Compiling on Cygwin(Win7 64bit) for iPhone [closed]

    - by Kenneth Noland
    Hey This is going to take a long while to explain, but the short version is that I am currently attempting to compile the LLVM GCC frontend for ARMv7 to compile apps for the Cortex-A8(iPhone 3GS). I'm running into an error from LD when compiling libgcc(part of the gcc compilation process) that has been driving me mad! The command is this: /usr/llvm-gcc-4.2-2.8.source/build/./gcc/xgcc \ -B/usr/llvm-gcc-4.2_2.8.source/build/./gcc \ -B/usr/local/arm-apple-darwin/bin \ -B/usr/local/arm-apple-darwin/lib \ -isystem /usr/local/arm-apple-darwin/include \ -isystem /usr/local/arm-apple-darwin/sys-include \ -O2 -g -W -Wall -Wwrite-strings -wstrict-prototypes -Wmissing-prototypes -Wold-style-definition -fno-inline -dynamiclib -nodefaultlibs -W1,-dead_strip \ -marm \ -install_name /usr/local/arm-apple-darwin/lib/libgcc_s.1.dylib \ -single_module -o ./libgcc_s.1.dylib.tmp \ -W1,-exported_symbols_list,libgcc/./libgcc.map -compatibility_version 1 -current_version 1.0 -DIN_GCC -DCROSS_DIRECTORY_STRUCTURE -DHAVE_GTHR_DEFAULT -DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED -Dinhibit_libc \ ... long list of .o files ... \ -lc And the result is typically a lot of undefined references to malloc, free, exit, etc. which typically indicate that libc is not getting compiled in. After going through the list of errors that ld is throwing, I see at the top that it is attempting to pull in /usr/lib/libc.a and complains that it is not the correct platform. Okay, that makes sense, so I spent 5 minutes on google and found an answer. Turns out that if I copy the libSystem.dylib and rename it to libc.dylib, that should solve the problem, but it doesn't. I couldn't find a copy of that file on my phone, so I pulled it directly from the SDK. I then get this strange error: ld64: in /usr/local/arm-apple-darwin/lib/libc.dylib, can't re-map file, errno=22 At this point, I did everything I could think of. I grabbed a fresh copy of my /usr/lib folder from my iphone and confirmed that libSystem.dylib(and libSystem.B.dylib) wasn't there. I unpacked the raw .ipsw package for iOS 4.2.1 and once again, I could not find a copy of libSystem.dylib there either. I unpacked the iPhoneSDK and MacOS SDK and I managed to find a copy of it in both, but that error just kept persisting. I copied libSystem.dylib, libSystem.B.dylib, tried all sorts of combinations of renaming to libc.dylib and still nothing but errors. I can't find a way to get it to recognize the file and link against it. I also tried linking against the libc.a located in the iphone SDK and that didn't work either. I checked what ./xgcc was firing off, and it was my freshly built copy of arm-apple-darwin-ld64 which should be fine. A little bit of background here. I built LLVM+Clang 2.8 with no errors, and I rebuilt the ODCCTools with some light modifications to get it to compile on Cygwin(I'll post my changes in a patch along with a tutorial if I can get this to work). I also grabbed the iphone-dev "includes" and "csu" project and those completed successfully, although there really is no point to them since I can't get it to link against crt0.a. I'm running out of ideas here. Can anyone help me out on this?

  • Automated SSRS deployment with the RS utility

    - by Stacy Vicknair
    If you’re familiar with SSRS and development you are probably aware of the SSRS web services. The RS utility is a tool that comes with SSRS that allows for scripts to be executed against against the SSRS web service without needing to create an application to consume the service. One of the better benefits of using this format rather than writing an application is that the script can be modified by others who might be involved in the creation and addition of scripts or management of the SSRS environment.   Reporting Services Scripter Jasper Smith from http://www.sqldbatips.com created Reporting Services Scripter to assist with the created of a batch process to deploy an entire SSRS environment. The helper scripts below were created through the modification of his generated scripts. Why not just use this tool? You certainly can. For me, the volume of scripts generated seems less maintainable than just using some common methods extracted from these scripts and creating a deployment in a single script file. I would, however, recommend this as a product if you do not think that your environment will change drastically or if you do not need to deploy with a higher level of control over the deployment. If you just need to replicate, this tool works great. Executing with RS.exe Executing a script against rs.exe is fairly simple. The Script Half the battle is having a starting point. For the scripting I needed to do the below is the starter script. A few notes: This script assumes integrated security. This script assumes your reports have one data source each. Both of the above are just what made sense for my scenario and are definitely modifiable to accommodate your needs. If you are unsure how to change the scripts to your needs, I recommend Reporting Services Scripter to help you understand how the differences. The script has three main methods: CreateFolder, CreateDataSource and CreateReport. Scripting the server deployment is just a process of recreating all of the elements that you need through calls to these methods. If there are additional elements that you need to deploy that aren’t covered by these methods, again I suggest using Reporting Services Scripter to get the code you would need, convert it to a repeatable method and add it to this script! Public Sub Main() CreateFolder("/", "Data Sources") CreateFolder("/", "My Reports") CreateDataSource("/Data Sources", "myDataSource", _ "Data Source=server\instance;Initial Catalog=myDatabase") CreateReport("/My Reports", _ "MyReport", _ "C:\myreport.rdl", _ True, _ "/Data Sources", _ "myDataSource") End Sub   Public Sub CreateFolder(parent As String, name As String) Dim fullpath As String = GetFullPath(parent, name) Try RS.CreateFolder(name, parent, GetCommonProperties()) Console.WriteLine("Folder created: {0}", name) Catch e As SoapException If e.Detail.Item("ErrorCode").InnerText = "rsItemAlreadyExists" Then Console.WriteLine("Folder {0} already exists and cannot be overwritten", fullpath) Else Console.WriteLine("Error : " + e.Detail.Item("ErrorCode").InnerText + " (" + e.Detail.Item("Message").InnerText + ")") End If End Try End Sub   Public Sub CreateDataSource(parent As String, name As String, connectionString As String) Try RS.CreateDataSource(name, parent,False, GetDataSourceDefinition(connectionString), GetCommonProperties()) Console.WriteLine("DataSource {0} created successfully", name) Catch e As SoapException Console.WriteLine("Error : " + e.Detail.Item("ErrorCode").InnerText + " (" + e.Detail.Item("Message").InnerText + ")") End Try End Sub   Public Sub CreateReport(parent As String, name As String, location As String, overwrite As Boolean, dataSourcePath As String, dataSourceName As String) Dim reportContents As Byte() = Nothing Dim warnings As Warning() = Nothing Dim fullpath As String = GetFullPath(parent, name)   'Read RDL definition from disk Try Dim stream As FileStream = File.OpenRead(location) reportContents = New [Byte](stream.Length-1) {} stream.Read(reportContents, 0, CInt(stream.Length)) stream.Close()   warnings = RS.CreateReport(name, parent, overwrite, reportContents, GetCommonProperties())   If Not (warnings Is Nothing) Then Dim warning As Warning For Each warning In warnings Console.WriteLine(Warning.Message) Next warning Else Console.WriteLine("Report: {0} published successfully with no warnings", name) End If   'Set report DataSource references Dim dataSources(0) As DataSource   Dim dsr0 As New DataSourceReference dsr0.Reference = dataSourcePath Dim ds0 As New DataSource ds0.Item = CType(dsr0, DataSourceDefinitionOrReference) ds0.Name=dataSourceName dataSources(0) = ds0     RS.SetItemDataSources(fullpath, dataSources)   Console.Writeline("Report DataSources set successfully")       Catch e As IOException Console.WriteLine(e.Message) Catch e As SoapException Console.WriteLine("Error : " + e.Detail.Item("ErrorCode").InnerText + " (" + e.Detail.Item("Message").InnerText + ")") End Try End Sub     Public Function GetCommonProperties() As [Property]() 'Common CatalogItem properties Dim descprop As New [Property] descprop.Name = "Description" descprop.Value = "" Dim hiddenprop As New [Property] hiddenprop.Name = "Hidden" hiddenprop.Value = "False"   Dim props(1) As [Property] props(0) = descprop props(1) = hiddenprop Return props End Function   Public Function GetDataSourceDefinition(connectionString as String) Dim definition As New DataSourceDefinition definition.CredentialRetrieval = CredentialRetrievalEnum.Integrated definition.ConnectString = connectionString definition.Enabled = True definition.EnabledSpecified = True definition.Extension = "SQL" definition.ImpersonateUser = False definition.ImpersonateUserSpecified = True definition.Prompt = "Enter a user name and password to access the data source:" definition.WindowsCredentials = False definition.OriginalConnectStringExpressionBased = False definition.UseOriginalConnectString = False Return definition End Function   Private Function GetFullPath(parent As String, name As String) As String If parent = "/" Then Return parent + name Else Return parent + "/" + name End If End Function

  • The Minimalist Approach to Content Governance - Request Phase

    - by Kellsey Ruppel
    Originally posted by John Brunswick. For each project, regardless of size, it is critical to understand the required ownership, business purpose, prerequisite education / resources needed to execute and success criteria around it. Without doing this, there is no way to get a handle on the content life-cyle, resulting in a mass of orphaned material. This lowers the quality of end user experiences.     The good news is that by using a simple process in this request phase - we will not have to revisit this phase unless something drastic changes in the project. For each of the elements mentioned above in this stage, the why, how (technically focused) and impact are outlined with the intent of providing the most value to a small team. 1. Ownership Why - Without ownership information it will not be possible to track and manage any of the content and take advantage of many features of enterprise content management technology. To hedge against this, we need to ensure that both a individual and their group or department within the organization are associated with the content. How - Apply metadata that indicates the owner and department or group that has responsibility for the content. Impact - It is possible to keep the content system optimized by running native reports against the meta-data and acting on them based on what has been outlined for success criteria. This will maximize end user experience, as content will be faster to locate and more relevant to the user by virtue of working through a smaller collection. 2. Business Purpose Why - This simple step will weed out requests that have tepid justification, as users will most likely not spend the effort to request resources if they do not have a real need. How - Use a simple online form to collect and workflow the request to management native to the content system. Impact - Minimizes the amount user generated content that is of low value to the organization. 3. Prerequisite Education Resources Needed Why - If a project cannot be properly staffed the probability of its success is going to be low. By outlining the resources needed - in both skill set and duration - it will cause the requesting party to think critically about the commitment needed to complete their project and what gap must be closed with regard to education of those resources. How - In the simple request form outlined above, resources and a commitment to fulfilling any needed education should be included with a brief acceptance clause that outlines the requesting party's commitment. Impact - This stage acts as a formal commitment to ensuring that resources are able to execute on the vision for the project. 4. Success Criteria Why - Similar to the business purpose, this is a key element in helping to determine if the project and its respective content should continue to exist if it does not meet its intended goal. How - Set a review point for the project content that will check the progress against the originally outlined success criteria and then determine the fate of the content. This can even include logic that will tell the content system to remove items that have not been opened by any users in X amount of time. Impact - This ensures that projects and their contents do not live past their useful lifespans. Just as with orphaned content, non-relevant information will slow user's access to relevant materials for the jobs. Request Phase Summary With a simple form that outlines the ownership of a project and its content, business purpose, education and resources, along with success criteria, we can ensure that an enterprise content management system will stay clean and relevant to end users - allowing it to deliver the most value possible. The key here is to make it straightforward to make the request and let the content management technology manage as much as possible through metadata, retention policies and workflow. Doing these basic steps will allow project content to get off to a great start in the enterprise! Stay tuned for the next installment - the "Create Phase" - covering security access and workflow involved in content creation, enabling a practical layer of governance over our enterprise content repository.

  • How to add Spatial Solr to a Solrnet query

    - by Flo
    Hi, I am running Solr on my windows machine using jetty. I have downloaded the Spatial Solr Plugin which I finally managed to get up and running. I am also using Solrnet to query against Solr from my asp.net mvc project. Now, adding data into my index seems to work fine and the SpatialTierUpdateProcessorFactory does work as well. The problem is: How do I add the spatial query to my normal query using the Solrnet library. I have tried adding it using the "ExtraParams" parameter but that didn't work very well. Here is an example of me trying to combine the spatial query with a data range query. The date range query works fine without the spatial query attached to it: new SolrQuery("{!spatial lat=51.5224 long=-2.6257 radius=10000 unit=km calc=arc threadCount=2}") && new SolrQuery(MyCustomQuery.Query) && new SolrQuery(DateRangeQuery); which results in the following query against Solr: (({!spatial lat=51.5224 long=-2.6257 radius=100 unit=km calc=arc threadCount=2} AND *:*) AND _date:[2010-05-07T13:13:37Z TO 2011-05-07T13:13:37Z]) And the error message I get back is: The remote server returned an error: (400) Bad Request. SEVERE: org.apache.solr.common.SolrException: org.apache.lucene.queryParser.Pars eException: Cannot parse '(({!spatial lat=51.5224 lng=-2.6257 radius=10000 unit= km calc=arc threadCount=2} AND *:*) AND _date:[2010-05-07T13:09:49Z TO 2011-05-0 7T13:09:49Z])': Encountered " <RANGEEX_GOOP> "lng=-2.6257 "" at line 1, column 2 4. Was expecting: "}" ... Now, the thing is if I use the Solr Web Admin page and execute the following query against it, everything works fine. {!spatial lat=50.8371 long=4.35536 radius=100 calc=arc unit=km threadcount=2}text:London What is the best/correct way to call the spatial function using SolrNet. Is the best way to somehow add that bit of the query manually to the query string and is so how? Any help is much appreciated!

  • .NET4: In-Process Side-by-Side Execution Explained

    - by emptyset
    Overview: I'm interested in learning more about the .NET4 "In-Process Side-by-Side Execution" of assemblies, and need additional information to help me demystify it. Motivation: The application in question is built against .NET2, and uses two third-party libraries that also work against .NET2. The application is deployed (via file copy) to client machines in a virtual environment that includes .NET2. Not my architecture, please bear with me. Goal: To see if it's possible to rebuild the application assemblies (or a subset) against .NET4, and ship the application as before, without changing the third-party libraries and including the .NET4 Client Profile (as described here) in the deployment. Steps Taken: The following articles were read, but didn't quite provide me enough information: In-Process Side-by-Side Execution: Browsed this article, and Scenario Two is the closest it comes to describing something that resembles my situation, but doesn't really cover it with any depth. ASP.NET Side-by-Side Execution Overview: This article covers a web application, but I'm dealing with a client WinForms application. CLR Team Blog: In-Process Side-by-Side: This is useful to explain how plug-ins to host processes function under .NET4, but I don't know if this applies to the third-party libraries. Further Steps: I'm also unclear on how to proceed upgrading a single .NET2 assembly to .NET4, with the overall application remaining in .NET2 (i.e. how to configure the solution/project files, if any special code needs to be included, etc.).

  • GHC 6.12 and MacPorts

    - by absz
    I recently installed GHC 6.12 and the Haskell Platform 2010.1.0.1 on my Intel MacBook running OS X 10.5.8, and initially, everything worked fine. However, I discovered that if I use cabal install to install a package which depends on a MacPorts library (e.g., cabal install --extra-lib-dirs=/opt/local/lib --extra-include-dirs=/opt/local/include gd), things work fine in GHCi, but if I try to compile, I get the error Linking test ... Undefined symbols: "_iconv_close", referenced from: _hs_iconv_close in libHSbase-4.2.0.0.a(iconv.o) "_iconv", referenced from: _hs_iconv in libHSbase-4.2.0.0.a(iconv.o) "_iconv_open", referenced from: _hs_iconv_open in libHSbase-4.2.0.0.a(iconv.o) ld: symbol(s) not found collect2: ld returned 1 exit status After some Googling, I found a long Haskell-cafe thread discussing this problem. The upshot seems to be that MacPorts installs an updated version of libiconv, and the binary interface is slightly different from the version included with the system. Consequently, if you try to link with any MacPorts library, the MacPorts libiconv gets linked in too; and since the base library was built to link against a different version of libiconv, things break. I've tried setting LD_LIBRARY_PATH and DYLD_LIBRARY_PATH and adding more flags to try to get it to look at /usr/lib again (e.g. cabal install --extra-lib-dirs=/opt/local/lib --extra-include-dirs=/opt/local/include --extra-lib-dirs=/usr/lib --extra-include-dirs=/usr/include gd), but neither worked. Uninstalling the MacPorts libiconv isn't really an option, since I have a bunch of ports installed which depend on it---including some ports I want Haskell to link to, like gd2. From what I've seen online, the upshot really seems to be "you're boned": you cannot link against any MacPorts library while compiling with GHC, and there doesn't seem to be a solution. However, that thread was from the end of 2009, so I figure there's a chance that someone has a solution, workaround, ridiculous hack… anything, really. So: does anybody know how to get GHC 6.12 to link against the system libiconv at the same time as it links to libraries from MacPorts? Or, failing that, a way to make linking not break in some other clever way?

  • configure.in: AM_DISABLE_SHARED doesn't change my Makefile

    - by t2k32316
    I'm extremely new to using Makefiles and autoconf. I'm using the Camellia image library and trying to statically link my code against their libraries. When I run "make" on the Camellia image library, I get libCamellia.a, .so, .la, and .so.0.0.0 files inside my /usr/local/lib directory. This is the command I use to compile my code with their libraries: gcc -L/usr/local/lib -lCamellia -o myprogram myprogram.c This works fine, but when I try to statically link, this is what I get: gcc -static -L/usr/local/lib -lCamellia -o myprogram myprogram.c /tmp/cck0pw70.o: In function `main': myprogram.c:(.text+0x23): undefined reference to `camLoadPGM' myprogram.c:(.text+0x55): undefined reference to `camAllocateImage' myprogram.c:(.text+0x97): undefined reference to `camZoom2x' myprogram.c:(.text+0x104): undefined reference to `camSavePGM' collect2: ld returned 1 exit status I want to statically link because I'm trying to modify the Camellia source code and I want to compare my version against theirs. So after some googling, I tried adding AM_DISABLE_SHARED into the configure.in file. But after running ./configure, I still get the exact same Makefile. After I "make install", I still get the same results above. What is an easy way to get two versions of my code, one with the original Camellia source code compiled and one with my modified version? I think static libraries should work. There is an easy way to get static libraries working or are there other simple solutions to my problem? I just don't want to re-"make" and re-"make install" everytime I want to compare my version against the original.

  • Credit card system implementation?

    - by Mark
    My site is going to have a credit system that basically works a lot like a credit card. Each user has an unlimited credit limit, but at the end of each week, they have to pay it off. For example, a user might make several purchases between March 1st and 7th, and then at the end of March 7th, they would be emailed an invoice that lists all their purchases during the week and a total that is due by the 14th. If they don't pay it off, their account is simply deactivated until they do. I'm just trying to wrap my head around how to implement this. I have a list of all their purchases, that's not a problem, but I'm just trying to figure out what to do with it. On the end of the 7th day, I could set up a cronjob to generate an invoice, which would basically have an id, and due date, and then I would need another many-to-many table to link all the purchases to the invoice. Then when a user adds money to their account, I guess it's applied against their current outstanding invoice? And what if they don't pay off their invoice by the time a new invoice rolls around, so now they have 2 outstanding ones, how do I know which to apply it against? Or do I make the cronjob check for any previous outstanding invoices, cancel them, and add a new item to the new invoice as "balance forward (+interest)"? How would you apply the money against an invoice? Would each payment have to be linked to an invoice, or could I just deposit it to their account credit, and then somehow figure out whats been paid and what hasn't? What if they pay in advance, before their invoice has been generated? Do I deduct it from their credit from the invoice upon generation, or at the end of the week when its due? There are so many ways to do this... Can anyone describe what approach they would take?

  • Abusing the word "library"

    - by William Pursell
    I see a lot of questions, both here on SO and elsewhere, about "maintaining common libraries in a VCS". That is, projects foo and bar both depend on libbaz, and the questioner is wondering how they should import the source for libbaz into the VCS for each project. My question is: WTF? If libbaz is a library, then foo doesn't need its source code at all. There are some libraries that are reasonably designed to be used in this manner (eg gnulib), but for the most part foo and bar ought to just link against the library. I guess my thinking is: if you cut-and-paste source for a library into your own source tree, then you obviously don't care about future updates to the library. If you care about updates, then just link against the library and trust the library maintainers to maintain a stable API. If you don't trust the API to remain stable, then you can't blindly update your own copy of the source anyway, so what is gained? To summarize the question: why would anyone want to maintain a copy of a library in the source code for a project rather than just linking against that library and requiring it as a dependency? If the only answer is "don't want the dependency", then why not just distribute a copy of the library along with your app, but keep them totally separate?

  • Are Parameters really enough to prevent Sql injections?

    - by Rune Grimstad
    I've been preaching both to my colleagues and here on SO about the goodness of using parameters in SQL queries, especially in .NET applications. I've even gone so far as to promise them as giving immunity against SQL injection attacks. But I'm starting to wonder if this really is true. Are there any known SQL injection attacks that will be successfull against a parameterized query? Can you for example send a string that causes a buffer overflow on the server? There are of course other considerations to make to ensure that a web application is safe (like sanitizing user input and all that stuff) but now I am thinking of SQL injections. I'm especially interested in attacks against MsSQL 2005 and 2008 since they are my primary databases, but all databases are interesting. Edit: To clarify what I mean by parameters and parameterized queries. By using parameters I mean using "variables" instead of building the sql query in a string. So instead of doing this: SELECT * FROM Table WHERE Name = 'a name' We do this: SELECT * FROM Table WHERE Name = @Name and then set the value of the @Name parameter on the query / command object.

  • Performance of VIEW vs. SQL statement

    - by Matt W.
    I have a query that goes something like the following: select <field list> from <table list> where <join conditions> and <condition list> and PrimaryKey in (select PrimaryKey from <table list> where <join list> and <condition list>) and PrimaryKey not in (select PrimaryKey from <table list> where <join list> and <condition list>) The sub-select queries both have multiple sub-select queries of their own that I'm not showing so as not to clutter the statement. One of the developers on my team thinks a view would be better. I disagree in that the SQL statement uses variables passed in by the program (based on the user's login Id). Are there any hard and fast rules on when a view should be used vs. using a SQL statement? What kind of performance gain issues are there in running SQL statements on their own against regular tables vs. against views. (Note that all the joins / where conditions are against indexed columns, so that shouldn't be an issue.) EDIT for clarification... Here's the query I'm working with: select obj_id from object where obj_id in( (select distinct(sec_id) from security where sec_type_id = 494 and ( (sec_usergroup_id = 3278 and sec_usergroup_type_id = 230) or (sec_usergroup_id in (select ug_gi_id from user_group where ug_ui_id = 3278) and sec_usergroup_type_id = 231) ) and sec_obj_id in ( select obj_id from object where obj_ot_id in (select of_ot_id from obj_form left outer join obj_type on ot_id = of_ot_id where ot_app_id = 87 and of_id in (select sec_obj_id from security where sec_type_id = 493 and ( (sec_usergroup_id = 3278 and sec_usergroup_type_id = 230) or (sec_usergroup_id in (select ug_gi_id from user_group where ug_ui_id = 3278) and sec_usergroup_type_id = 231) ) ) and of_usage_type_id = 131 ) ) ) ) or (obj_ot_id in (select of_ot_id from obj_form left outer join obj_type on ot_id = of_ot_id where ot_app_id = 87 and of_id in (select sec_obj_id from security where sec_type_id = 493 and ( (sec_usergroup_id = 3278 and sec_usergroup_type_id = 230) or (sec_usergroup_id in (select ug_gi_id from user_group where ug_ui_id = 3278) and sec_usergroup_type_id = 231) ) ) and of_usage_type_id = 131 ) and obj_id not in (select sec_obj_id from security where sec_type_id = 494) )

  • MySQL "OR MATCH" hangs (very slow) on multiple tables

    - by Kerry
    After learning how to do MySQL Full-Text search, the recommended solution for multiple tables was OR MATCH and then do the other database call. You can see that in my query below. When I do this, it just gets stuck in a "busy" state, and I can't access the MySQL database. SELECT a.`product_id`, a.`name`, a.`slug`, a.`description`, b.`list_price`, b.`price`, c.`image`, c.`swatch`, e.`name` AS industry, MATCH( a.`name`, a.`sku`, a.`description` ) AGAINST ( '%s' IN BOOLEAN MODE ) AS relevance FROM `products` AS a LEFT JOIN `website_products` AS b ON (a.`product_id` = b.`product_id`) LEFT JOIN ( SELECT `product_id`, `image`, `swatch` FROM `product_images` WHERE `sequence` = 0) AS c ON (a.`product_id` = c.`product_id`) LEFT JOIN `brands` AS d ON (a.`brand_id` = d.`brand_id`) INNER JOIN `industries` AS e ON (a.`industry_id` = e.`industry_id`) WHERE b.`website_id` = %d AND b.`status` = %d AND b.`active` = %d AND MATCH( a.`name`, a.`sku`, a.`description` ) AGAINST ( '%s' IN BOOLEAN MODE ) OR MATCH ( d.`name` ) AGAINST ( '%s' IN BOOLEAN MODE ) GROUP BY a.`product_id` ORDER BY relevance DESC LIMIT 0, 9 Any help would be greatly appreciated. EDIT All the tables involved are MyISAM, utf8_general_ci. Here's the EXPLAIN SELECT statement: id select_type table type possible_keys key key_len ref rows Extra 1 PRIMARY a ALL NULL NULL NULL NULL 16076 Using temporary; Using filesort 1 PRIMARY b ref product_id product_id 4 database.a.product_id 2 1 PRIMARY e eq_ref PRIMARY PRIMARY 4 database.a.industry_id 1 1 PRIMARY <derived2> ALL NULL NULL NULL NULL 23261 1 PRIMARY d eq_ref PRIMARY PRIMARY 4 database.a.brand_id 1 Using where 2 DERIVED product_images ALL NULL NULL NULL NULL 25933 Using where I don't know how to make that look neater -- sorry about that UPDATE it returns the query after 196 seconds (I think correctly). The query without multiple tables takes about .56 seconds (which I know is really slow, we plan on changing to solr or sphinx soon), but 196 seconds?? If we could add a number to the relevance if it was in the brand name ( d.name ), that would also work

  • Select statement with multiple 'where' fields using same value without duplicating text

    - by kdbdallas
    I will start by saying that I don't think what I want can be done, but that said, I am hoping I am wrong and someone knows more than me. So here is your chance... Prove you are smarter than me :) I want to do a search against a SQLite table looking for any records that "are similar" without having to write out the query in long hand. To clarify this is how I know I can write the query: select * from Articles where title like '%Bla%' or category like '%Bla%' or post like '%Bla%' This works and is not a huge deal if you are only checking against a couple of columns, but if you need to check against a bunch then your query can get really long and nasty looking really fast, not to mention the chance for typos. (ie: 'Bla%' instead of '%Bla%') What I am wondering is if there is a short hand way to do this? *This next code does not work the way I want, but just shows kind of what I am looking for select * from Articles where title or category or post like '%Bla%' Anyone know if there is a way to specify that multiple 'where' columns should use the same search value without listing that same search value for every column? Thanks in advance!
