  • Sesame Data Browser: filtering, sorting, selecting and linking

    - by Fabrice Marguerie
    I have deferred the post about how Sesame is built in favor of publishing a new update.This new release offers major features such as the ability to quickly filter and sort data, select columns, and create hyperlinks to OData. Filtering, sorting, selecting In order to filter data, you just have to use the filter row, which becomes available when you click on the funnel button: You can then type some text and select an operator: The data grid will be refreshed immediately after you apply a filter. It works in the same way for sorting. Clicking on a column will immediately update the query and refresh the grid.Note that multi-column sorting is possible by using SHIFT-click: Viewing data is not enough. You can also view and copy the query string that returns that data: One more thing you can to shape data is to select which columns are displayed. Simply use the Column Chooser and you'll be done: Again, this will update the data and query string in real time: Linking to Sesame, linking to OData The other main feature of this release is the ability to create hyperlinks to Sesame. That's right, you can ask Sesame to give you a link you can display on a webpage, send in an email, or type in a chat session. You can get a link to a connection: or to a query: You'll note that you can also decide to embed Sesame in a webpage... Here are some sample links created via Sesame: Netflix movies with high ratings, sorted by release year Netflix horror movies from the 21st century Northwind discontinued products with remaining stock Netflix empty connection I'll give more examples in a post to follow. There are many more minor improvements in this release, but I'll let you find out about them by yourself :-)Please try Sesame Data Browser now and let me know what you think! PS: if you use Sesame from the desktop, please use the "Remove this application" command in the context menu of the destkop app and then "Install on desktop" again in your web browser. I'll activate automatic updates with the next release.

  • Macedonian Code Camp 2011

    - by hajan
    Autumn was filled with lot of conferences, events, speaking engagements and many interesting happenings in Skopje, Macedonia. First at October 20, I was speaking at Microsoft Vizija 9 on topic ASP.NET MVC3 and Razor. One week ago, November 15 I was speaking for first time on topic not related to web development (but still deployment of web apps was part of the demos) on topic “Cloud Computing – Windows Azure” at Microsoft BizSpark Bootcamp. The next event, which is the biggest event by the number of visitors and number of tracks is the Code Camp 2011 event. After we opened the registrations for the event, we sold out (free) 600 tickets in the first 15 hours! We all got astonished by the extremely big number of responses we’ve got… In this event, I can freely say that we expect about 700 attendees to come, and we already have 900+ registered. The event will be held at Saturday, 26 November 2011. At Code Camp 2011, I will speak on topic ASP.NET MVC Best Practices. There are many interesting things to say on this presentation, I will mainly focus on Tips, Tricks, Guidelines and other Practices that I have been using in real-life projects developed by using ASP.NET MVC Framework, with special focus on ASP.NET MVC3 and the next release, ASP.NET MVC4 Developer Preview. There are big number of known local and regional speakers, including 7 MVPs. You can find more info about this event at the official event website: http://codecamp.mkdot.net As for my session, if you have some interesting trick or good practice you have been using in your ASP.NET MVC projects, you can freely share it with me… If I find it interesting and if it’s not part of the current practices I have included for the presentation (I can’t tell you which ones for now… *secret* ;))… I will consider including it in the presentation. Stay tuned for more info soon… Regards, Hajan

  • TechEd 2012: Day 3 &ndash; Build Me A Solution

    - by Tim Murphy
    While digesting my lunch it was time to digest some TFS Build information. While much of my time is spent wearing my developer’s hat I am still a jack of all trades and automated builds are an important aspect of any project.  Because of this I was looking forward to finding out what new features are available in the latest release of Team Foundation Server. The first feature that caught my attention is the TFS Admin Client.  After being used to dealing with NAnt in the past it is nice to see a build a configuration GUI that is so flexible and well thought out.  The bonus is that it the tools that are incorporated in Visual Studio 2012 are just as feature rich.  Life is good. Since automated builds are the hub of your development process in a continuous integration shop I was really interested in the process related options. The biggest value add that I noticed was merge gated check-ins.  Merge or batch gated check-ins are an interesting concept.  If the build breaks with all the changes then TFS will run separate builds for each of the check-ins.  This ability to identify the actual offending check-in can save a lot of time and gray hair. The safari of TFS Build that was this session was packed with attractions.  How do you set it up builds, what are the different flavors of builds, how does the system report how the build went?  I would suggest anyone who is responsible for build automation spend some serious time with TFS 2012 and VS2012. del.icio.us Tags: Team Foundation Server 2012,TFS,Build,TechEd,TechEd 2012,Visual Studio 2012

  • SQL SERVER – Difference between COUNT(DISTINCT) vs COUNT(ALL)

    - by pinaldave
    This blog post is written in response to the T-SQL Tuesday hosted by Jes Schultz Borland. Earlier today, I was presenting a 45-minute session at the Community College about “The Beginning SQL Server Database”. One of the students asked me the following question. What is the difference between COUNT(DISTINCT) vs COUNT(ALL)? I found this question from the student very interesting. He seems to have read the documentation (Book Online) and was then asking me this question. I always carry laptop which has SQL Server installed. I quickly opened it and ran the following script. After looking at the result, I think it was clear to everybody. Here is the script: SELECT COUNT([Title]) Value FROM [AdventureWorks].[Person].[Contact] GO SELECT COUNT(ALL [Title]) ALLValue FROM [AdventureWorks].[Person].[Contact] GO SELECT COUNT(DISTINCT [Title]) DistinctValue FROM [AdventureWorks].[Person].[Contact] GO The above script will give me the following results. You can clearly notice from the result set that COUNT (ALL ColumnName) is the same as COUNT(ColumnName). The reality is that the “ALL” is actually  the default option and it needs not to be specified. The ALL keyword includes all the non-NULL values. I know this is very simple and may be it does not change how we work; however looking at the whole angle, I really enjoyed the question.

  • when to introduce an application services tier in an n-tier application

    - by user20358
    I am developing a web based application whose primary objective is to fetch data from the database, display it on the UI, take in user inputs and write them back to the database. The application is not going to be doing any industrial strength algorithm crunching, but will be receiving a very high number of hits at peak times (described below) which will be changing thru the day. The layers are your typical Presentation, Business, Data. The data layer is taken care of by the database server. The business layer will contain the DAL component to access the database server over tcp. The choices I have to separate these layers into tiers are: The presentation and business layers can be either kept on the same tier. The presentation layer on a separate tier by itself and the business layer on a separate tier by itself. In the case of choice 2, the business layer will be accessed by the presentation layer using a WCF service either over http or tcp. I don't see any heavy processing being done on the Business layer, so I am leaning towards option 1 above. I also feel for the same reason, adding a new tier will only introduce the network latency. However, in terms of scalability in case I need to scale up or scale out, which is a better way to go? This application will need to be able to support up to 6 million users an hour. There will be a reasonable amount of data in each user session, storing user's preferences and other details. I will be using page level caching as well.

  • I spoke at SQL Saturday #77 and all I got was this really awesome speaker's shirt!

    - by Most Valuable Yak (Rob Volk)
    Yeah, it was 2 weeks ago, but I'm finally blogging about something! I presented Revenge: The SQL! at SQL Saturday #77 in Pensacola on June 4.  The session abstract is here, and you can download the slides from that page too.  You can see how I look in the speaker's shirt here. Overall it went pretty well.  I discovered a new bit of evil just that morning and in a carefully considered, agonizing decision-making process that was full documented, tested, and approved…nah, I just went ahead and added it at the last minute.  Which worked out even better than (not) planned, since it screwed me up a bit and made my point perfectly.  I had a few fans in the audience, and one of them recorded it for blackmail material posterity. I'd like to thank Karla Landrum (blog | twitter) and all the volunteers for putting together such a great event, and for being kind enough to let me present. (Note to Karla: I'll get the next $100 to you as soon as I can.  Might need a few extra days on the next $100.) Thanks to Audrey (blog | twitter), Peg, and Dorothy for attending and keeping the heckling down.  Thanks also to Aaron (blog | twitter) for providing room and board and also not heckling.  Thanks to Julie (blog | twitter) for coming up with the title for the presentation.  (boo to Julie for getting sick and bailing out on us)  And thanks to all of them for listening to a preview and offering their suggestions and advice! Cross your fingers that I get accepted at SQL Saturday 81 in Birmingham, SQL Saturday 85 in Orlando, or SQL Saturday 89 in Atlanta, or just attend them anyway!

  • Tell me what&rsquo;s wrong! &ndash; An XNA sample demonstrating exception handling and reporting in

    - by George Clingerman
    I’ve always enjoyed using Nick Gravelyn’s exception handling in all of my games. You’re always going to encounter those unhandled exception that your players are going to ferret out and having a method to display them rather than just crashing to the dashboard is definitely more of an elegant solution. But the other day I got to thinking…what if we could do more? What if instead of just displaying the error, we could encourage the players to send us the error. So I started playing with that an expanding upon Nick’s sample code to see what I could come up with. I got close to what I envisioned, but unfortunately there were some limitations to just what the XNA API could do. In my head I was picturing the players hitting “Send Message” and a 360 message would just be sent to the XBLIG developer. Unfortunately, you can only send messages in an XNA game to someone you’re currently in a network session with. Since I didn’t want to have a 360 server running all the time, virally connecting to players just to get error messages, I did the next best thing and just open up a 360 message and encourage them to manually enter the gamertag. Maybe someday we’ll be able to do that a little better, but this works for now. In the sample, players can hit the “A” button or key to generate in an exception. If the debugger is not attached, then the Exception message screen will be shown explaining what has happened and giving the player a chance to send a 360 message to the gamertag provided or maybe even just send an email. Nick’s code has been changed just a bit. It now accepts any PlayerIndex (no longer hard coded to just PlayerIndex.One) and it no longer uses a MessageBox to get the users selection. The code has also been modified so that it works both for the 360 and for the PC. Check out “Tell me what’s wrong!” and let me know if you have any thoughts or suggestions. I really do appreciate the feedback.

  • Manage SQL Server Connectivity through Windows Azure Virtual Machines Remote PowerShell

    - by SQLOS Team
    Manage SQL Server Connectivity through Windows Azure Virtual Machines Remote PowerShell Blog This blog post comes from Khalid Mouss, Senior Program Manager in Microsoft SQL Server. Overview The goal of this blog is to demonstrate how we can automate through PowerShell connecting multiple SQL Server deployments in Windows Azure Virtual Machines. We would configure TCP port that we would open (and close) though Windows firewall from a remote PowerShell session to the Virtual Machine (VM). This will demonstrate how to take the advantage of the remote PowerShell support in Windows Azure Virtual Machines to automate the steps required to connect SQL Server in the same cloud service and in different cloud services.  Scenario 1: VMs connected through the same Cloud Service 2 Virtual machines configured in the same cloud service. Both VMs running different SQL Server instances on them. Both VMs configured with remote PowerShell turned on to be able to run PS and other commands directly into them remotely in order to re-configure them to allow incoming SQL connections from a remote VM or on premise machine(s). Note: RDP (Remote Desktop Protocol) is kept configured in both VMs by default to be able to remote connect to them and check the connections to SQL instances for demo purposes only; but not actually required. Step 1 – Provision VMs and Configure Ports   Provision VM1; named DemoVM1 as follows (see examples screenshots below if using the portal):   Provision VM2 (DemoVM2) with PowerShell Remoting enabled and connected to DemoVM1 above (see examples screenshots below if using the portal): After provisioning of the 2 VMs above, here is the default port configurations for example: Step2 – Verify / Confirm the TCP port used by the database Engine By the default, the port will be configured to be 1433 – this can be changed to a different port number if desired.   1. RDP to each of the VMs created below – this will also ensure the VMs complete SysPrep(ing) and complete configuration 2. Go to SQL Server Configuration Manager -> SQL Server Network Configuration -> Protocols for <SQL instance> -> TCP/IP - > IP Addresses   3. Confirm the port number used by SQL Server Engine; in this case 1433 4. Update from Windows Authentication to Mixed mode   5.       Restart SQL Server service for the change to take effect 6.       Repeat steps 3., 4., and 5. For the second VM: DemoVM2 Step 3 – Remote Powershell to DemoVM1 Enter-PSSession -ComputerName condemo.cloudapp.net -Port 61503 -Credential <username> -UseSSL -SessionOption (New-PSSessionOption -SkipCACheck -SkipCNCheck) Your will then be prompted to enter the password. Step 4 – Open 1433 port in the Windows firewall netsh advfirewall firewall add rule name="DemoVM1Port" dir=in localport=1433 protocol=TCP action=allow Output: netsh advfirewall firewall show rule name=DemoVM1Port Rule Name:                            DemoVM1Port ---------------------------------------------------------------------- Enabled:                              Yes Direction:                            In Profiles:                             Domain,Private,Public Grouping:                             LocalIP:                              Any RemoteIP:                             Any Protocol:                             TCP LocalPort:                            1433 RemotePort:                           Any Edge traversal:                       No Action:                               Allow Ok. Step 5 – Now connect from DemoVM2 to DB instance in DemoVM1 Step 6 – Close port 1433 in the Windows firewall netsh advfirewall firewall delete rule name=DemoVM1Port Output: Deleted 1 rule(s). Ok. netsh advfirewall firewall show  rule name=DemoVM1Port No rules match the specified criteria.   Step 7 – Try to connect from DemoVM2 to DB Instance in DemoVM1  Because port 1433 has been closed (in step 6) in the Windows Firewall in VM1 machine, we can longer connect from VM3 remotely to VM1. Scenario 2: VMs provisioned in different Cloud Services 2 Virtual machines configured in different cloud services. Both VMs running different SQL Server instances on them. Both VMs configured with remote PowerShell turned on to be able to run PS and other commands directly into them remotely in order to re-configure them to allow incoming SQL connections from a remote VM or on on-premise machine(s). Note: RDP (Remote Desktop Protocol) is kept configured in both VMs by default to be able to remote connect to them and check the connections to SQL instances for demo purposes only; but not actually needed. Step 1 – Provision new VM3 Provision VM3; named DemoVM3 as follows (see examples screenshots below if using the portal): After provisioning is complete, here is the default port configurations: Step 2 – Add public port to VM1 connect to from VM3’s DB instance Since VM3 and VM1 are not connected in the same cloud service, we will need to specify the full DNS address while connecting between the machines which includes the public port. We shall add a public port 57000 in this case that is linked to private port 1433 which will be used later to connect to the DB instance. Step 3 – Remote Powershell to DemoVM1 Enter-PSSession -ComputerName condemo.cloudapp.net -Port 61503 -Credential <UserName> -UseSSL -SessionOption (New-PSSessionOption -SkipCACheck -SkipCNCheck) You will then be prompted to enter the password.   Step 4 – Open 1433 port in the Windows firewall netsh advfirewall firewall add rule name="DemoVM1Port" dir=in localport=1433 protocol=TCP action=allow Output: Ok. netsh advfirewall firewall show rule name=DemoVM1Port Rule Name:                            DemoVM1Port ---------------------------------------------------------------------- Enabled:                              Yes Direction:                            In Profiles:                             Domain,Private,Public Grouping:                             LocalIP:                              Any RemoteIP:                             Any Protocol:                             TCP LocalPort:                            1433 RemotePort:                           Any Edge traversal:                       No Action:                               Allow Ok.   Step 5 – Now connect from DemoVM3 to DB instance in DemoVM1 RDP into VM3, launch SSM and Connect to VM1’s DB instance as follows. You must specify the full server name using the DNS address and public port number configured above. Step 6 – Close port 1433 in the Windows firewall netsh advfirewall firewall delete rule name=DemoVM1Port   Output: Deleted 1 rule(s). Ok. netsh advfirewall firewall show  rule name=DemoVM1Port No rules match the specified criteria.  Step 7 – Try to connect from DemoVM2 to DB Instance in DemoVM1  Because port 1433 has been closed (in step 6) in the Windows Firewall in VM1 machine, we can no longer connect from VM3 remotely to VM1. Conclusion Through the new support for remote PowerShell in Windows Azure Virtual Machines, one can script and automate many Virtual Machine and SQL management tasks. In this blog, we have demonstrated, how to start a remote PowerShell session, re-configure Virtual Machine firewall to allow (or disallow) SQL Server connections.

  • 11 ADF Mobile Apps in 30 Hours

    - by Shay Shmeltzer
    The Oracle ADF Mobile team took part in a special "hackathon" this weekend, where 11 teams of new college hires who joined Oracle lately spent 30 hours building enterprise mobile applications leveraging ADF Mobile. One important thing to note - none of the participants worked with Oracle ADF Mobile before! In fact 90% of them didn't develop with ADF previously. All they had is a 2 hour training session before the event - and that's all they needed. From that point on they were able to build great cross device mobile applications. So what did they build? Here are some examples: A mileage expense tracking system: An ad campaign analysis system An expense report entry system Bug tracking system with data analysis: Carpooling social system: College Hiring system with CV scanning: Shipment management system for Farmers: Project time entry system: For sale post-it system (with item location): Conference event experience system with conference map and twitter feed integration: It was great to see how fast developers were able to learn and leverage ADF Mobile - and how creative the teams were. Here they are in action: So how about you? What would you build next? What would be your first ADF Mobile application? Start today!

  • Use 3 monitors w/built-in intel adapter + two old nvidia PCI cards on 10.10?

    - by Kendall Gifford
    I'd like to move from windows with my current workstation. The only thing holding me back is that I have 3 monitors connected to the system and I really take advantage of the real estate when working. I just installed Ubuntu 10.10 on the system and one of the monitors is up and running just fine. This monitor is connected to the built-in Intel adapter. I also have two old nVidia GeForce4 MX 4000 (nv19pl) cards in my two PCI slots with two monitors connected to them respectively. I installed the legacy (and proprietary) nVidia drivers (the nvidia-96 package) that claims to support these old cards. Now the question is how to get X configured to use all adapters (using two different drivers) so I can use all three monitors (and is this even possible)? From what I've read, it looks like I'll have to write an xorg.conf file since the nVidia driver doesn't support the auto-magic configuration supported by other drivers. On this site: http://wiki.ubuntu.com/X/Config it says that on 10.10 I just need to write an xorg.conf "containing only those sections and options that you need to override Xorg's autoconfigurated settings". So, does this mean I can get away with only including the nVidia-specific configuration stuff and all else will get auto-configured? Or, will providing a config with a "Device" section overrule the auto-magic from detecting/using the Intel adapter? I ran the included nvidia-xconfig to generate a basic, nVidia-specific xorg.conf but I'm hesitant to reboot with it in place, suspecting I'll have a screwed up display. Also, is there any way (any tool or command) to generate an xorg.conf from the current, auto-configured running state of an X session? If I have to write a full, complete config, I'd rather start with one that includes everything that's been auto-detected thus far (and merge it with my nVidia version). Anyhow, any info and thoughts are greatly appreciated (as are answers).

  • Rails/Node.js interaction

    - by lpvn
    I and my co-worker are developing a web application with rails and node.js and we can't reach a consensus regarding a particular architectural decision. Our setup is basically a rails server working with node.js and redis, when a client makes a http request to our rails API in some cases our rails application posts the response to a redis database and then node.js transmits the response via websocket. Our disagreement occurs in the following point: my co-worker thinks that using node.js to send data to clients is somewhat business logic and should be inside the model, so in the first code he wrote he used commands of broadcast in callbacks and other places of the model, he's convinced that the models are the best place for the interaction between rails and node. I on the other hand think that using node.js belongs to the runtime realm, my take is that the broadcast commands and other node.js interactions should be in the controller and should only be used in a model if passed through a well defined interface, just like the situation when a model needs to access the current user of a session. At this point we're tired of arguing over this same thing and our discussion consists in us repeating to ourselves our same opinions over and over. Could anyone, preferably with experience in the same setup, give us an unambiguous response saying which solution is more adequate and why it is?

  • Continuous Integration using Docker

    - by Leon Mergen
    One of the main advantages of Docker is the isolated environment it brings, and I want to leverage that advantage in my continuous integration workflow. A "normal" CI workflow goes something like this: Poll repository for changes Pull from repository Install dependencies Run tests In a Dockerized workflow, it would be something like this: Poll repository for changes Pull from repository Build docker image Run docker image as container Run tests Kill docker container My problem is with the "run tests" step: since Docker is an isolated environment, intuitively I would like to treat it as one; this means the preferred method of communication are sockets. However, this only works well in certain situations (a webapp, for example). When testing different kind of services (for example, a background service that only communicated with a database), a different approach would be required. What is the best way to approach this problem? Is it a problem with my application's design, and should I design it in a more TDD, service-oriented way that always listens on some socket? Or should I just give up on isolation, and do something like this: Poll repository for changes Pull from repository Build docker image Run docker image as container Open SSH session into container Run tests Kill docker container SSH'ing into the container seems like an ugly solution to me, since it requires deep knowledge of the contents of the container, and thus break the isolation. I would love to hear SO's different approaches to this problem.

  • Cannot FTP without simultaneous SSH connection?

    - by Lucas
    I'm trying to set up an old box as a backup server (running 10.04.4 LTS). I intend to use 3rd party software on my PC to periodically connect to my server via FTP(S) and to mirror certain files. For some reason, all FTP connection attempts fail UNLESS I'm simultaneously connected via SSH. For example, if I use putty to test the connection to port 21, the system hangs and times out. I get: 220 Connected to LeServer USER lucas 331 Please specify the password. PASS [password] <cursor> However, when I'm simultaneously logged in (in another session) everything works: 220 Connected to LeServer USER lucas 331 Please specify the password. PASS [password] 230 Login successful. Basically, this means that my software will never be able to connect on its own, as intended. I know that the correct port is open because it works (sometimes) and nmap gives me: Starting Nmap 5.00 ( http://nmap.org ) at 2012-03-20 16:15 CDT Interesting ports on xx.xxx.xx.x: Not shown: 995 closed ports PORT STATE SERVICE 21/tcp open ftp 22/tcp open ssh 53/tcp open domain 139/tcp open netbios-ssn 445/tcp open microsoft-ds Nmap done: 1 IP address (1 host up) scanned in 0.15 seconds My only hypothesis is that this has something to do with iptables. Maybe it's allowing only established connections? I don't think that's how I set it up, but maybe? Here's my iptables rules for INPUT: lucas@rearden:~$ sudo iptables -L INPUT Chain INPUT (policy DROP) target prot opt source destination fail2ban-ssh tcp -- anywhere anywhere multiport dports ssh ufw-before-logging-input all -- anywhere anywhere ufw-before-input all -- anywhere anywhere ufw-after-input all -- anywhere anywhere ufw-after-logging-input all -- anywhere anywhere ufw-reject-input all -- anywhere anywhere ufw-track-input all -- anywhere anywhere ACCEPT tcp -- anywhere anywhere tcp dpt:ftp I'm using vsftpd. Any thoughts/resources on how I could fix this? L

  • Ubuntu 12.04 LTS loops the login screen unless you login as Guest

    - by Mário Silva
    I am running a VMWare Player with a Ubuntu 12.04 LTS Precise Pangloin as Guest on my Windows 7. Sometimes I get the shutdown blue screen error in Windows, this time it happened when I was running the Player. When I restarted everything Ubuntu gave the not so unfamiliar in this forum Login Loop in adminstrator login. I login and there's this black screen where I can only read: "piix4...smbus:0.0.0.07.3 Host Smbus controller not enabled" . When I go to the Prompt in root mode it fails to update and only upgraded, specially some plugins ( I think graphic plugins) which also appear in one an error message after quitting the prompt, but they´are successfully installed. They are not the error message. After that I have been working with the Fail/safe Mode recovery panel. When I try to update via Root I get errors like this: W:failed to fetch http://extras.ubuntu.com/ubuntu/dists/precise/release.gpg could not resolve 'extras/ubuntu.com There are 8 more like this referring to areas like: -archive/canonical.com -ppa.Launchpad.net -security.Ubuntu.com -Us.archive.ubuntu.com - release.gpg precise-updates/release.gpg precise_backport/release.gpg Final Message: some index files failed to download.....they have been ignored or old files are used. The black screens most of the time pass by too fast for me to pick up any information. But in general I think I have done everything I was able to in the recovery panel including updating network and graphic packages and recovering filesystem packages and the basic stuff ( I am a beginner regarding Linux ) in the root prompt. Now I am stuck in this screen with graphic options: - Run in low-graphics mode just for one session - Reconfigure Graphics - Troubleshoot the error - Exit to console login I am trying to choose to reconfigure graphics but the mouse disappears in the virtual machine screen and sometimes when options change ity´s only the first and last option. ut this happens from the blue without messages. This particular option menu is in the regular GUI style against a black screen in Terminal style. Really strange. Thanx in advance, all is welcome and appreciated.

  • Caching WCF javascript proxy on browser

    - by oazabir
    When you use WCF services from Javascript, you have to generate the Javascript proxies by hitting the Service.svc/js. If you have five WCF services, then it means five javascripts to download. As browsers download javascripts synchronously, one after another, it adds latency to page load and slows down page rendering performance. Moreover, the same WCF service proxy is downloaded from every page, because the generated javascript file is not cached on browser. Here is a solution that will ensure the generated Javascript proxies are cached on browser and when there is a hit on the service, it will respond with HTTP 304 if the Service.svc file has not changed. Here’s a Fiddler trace of a page that uses two WCF services. You can see there are two /js hits and they are sequential. Every visit to the same page, even with the same browser session results in making those two hits to /js. Second time when the same page is browsed: You can see everything else is cached, except the WCF javascript proxies. They are never cached because the WCF javascript proxy generator does not produce the necessary caching headers to cache the files on browser. Here’s an HttpModule for IIS and IIS Express which will intercept calls to WCF service proxy. It first checks if the service is changed since the cached version on the browser. If it has not changed then it will return HTTP 304 and not go through the service proxy generation process. Thus it saves some CPU on server. But if the request is for the first time and there’s no cached copy on browser, it will deliver the proxy and also emit the proper cache headers to cache the response on browser. http://www.codeproject.com/Articles/360437/Caching-WCF-javascript-proxy-on-browser Don’t forget to vote.

  • Pub banter - content strategy at the ballot box?

    - by Roger Hart
    Last night, I was challenged to explain (and defend) content strategy. Three sheets to the wind after a pub quiz, this is no simple task, but I hope I acquitted myself passably. I say "hope" because there was a really interesting question I couldn't answer to my own satisfaction. I wonder if any of you folks out there in the ethereal internet hive-mind can help me out? A friend - a rather concrete thinker who mathematically models complex biological systems for a living - pointed out that my examples were largely routed in business-to-business web sales and support. He challenged me with: Say you've got a political website, so your goal is to have somebody read it and vote for you - how do you measure the effectiveness of that content? Well, you would. umm. Oh dear. I guess what we're talking about here, to yank it back to my present comfort zone, is a sales process where your point of conversion is off the site. The political example is perhaps a little below the belt, since what you can and can't do, and what data you can and can't collect is so restricted. You can't throw up a "How did you hear about this election?" questionnaire in the polling booth. Exit polls don't pull in your browsing history and site session information. Not everyone fatuously tweets and geo-tags each moment of their lives. Oh, and folks lie. The business example might be easier to attack. You could have, say, a site for a farm shop that only did over the counter sales. Either way, it's tricky. I fell back on some of the work I've done usability testing and benchmarking documentation, and suggested similar, quick and dirty, small sample qualitative UX trials. I'm not wholly sure that was right. Any thoughts? How might we measure and curate for this kind of discontinuous conversion?

  • Boot failure after update and system crash 11.10

    - by Alubuntu
    I'm using: Dell XPS M1330 laptop, Ubuntu 11.10 32bits, single boot (only Linux OS), Virtualbox (with Windows XP on virtual machine). System crashed while working with a very heavy image on GIMP (and Virtualbox was on). During the same session, I made an automatic system update, but don't know what was exactly updated. After the crash the system doesn't boot. Always freezes on terminal screen but at different stages, ""Starting CUPS printing spooler/server", "Checking battery state", "mountall: plymouth command failed", etc. Sometimes indicates [failed] in some of the processes and sometimes they're all [ok]. Did a Boot info summary with boot-repair and gave me this report http://paste.ubuntu.com/1050743/ This is not a new install, have been using it for almost 6 months...though since last month it couldn't halt..it started shutting down and stopped at black screen with fan on and on/off light still on (I used to finish the shutdown process by forcing halt with a long-press of the power button). I don't know if these has anything to do with the boot failure. Is there anyway I can solve this issue (the boot failure) or make some sort of system check to find out what is the cause of the problem? I wasn't sure if this was the right place to ask the question, so I also did it at https://answers.launchpad.net/ubuntu/+question/201004
