  • Sitecore Item Web API and Json.Net Test Drive (Part II –Strongly Typed)

    - by jonel
    In the earlier post I did related to this topic, I have talked about using Json.Net to consume the result of Sitecore Item Web API. In that post, I have used the keyword dynamic to express my intention of consuming the returned json of the API. In this article, I will create some useful classes to write our implementation of consuming the API using strongly-typed. We will start of with the Record class which will hold the top most elements the API will present us. Pretty straight forward class. It has 2 properties to hold the statuscode and the result elements. If you intend to use a different property name in your class from the json property, you can do so by passing a string literal of the json property name to the JsonProperty attribute and name your class property differently. If you look at the earlier post, you will notice that the API returns an array of items that contains all of the Sitecore content item or items and stores them under the result->items array element. To be able to map that array of items, we have to write a collection property and decorate that with the JsonProperty attribute. The JsonItem class is a simple class which will map to the corresponding item property contained in the array. If you notice, these properties are just the basic Sitecore fields. And here’s the main portion of this post that will binds them all together. And here’s the output of this code. In closing, the same result can be achieved using the dynamic keyword or defining classes to map the json propery returned by the Sitecore Item Web API. With a little bit more of coding, you can take advantage of power of strongly-typed solution. Have a good week ahead of you.

  • Move Data into the Grid for Scalable, Predictable Response Times

    - by JuergenKress
    CloudTran is pleased to introduce the availability of the CloudTran Transaction and Persistence Manager for creating scalable, reliable data services on the Oracle Coherence In-Memory Data Grid (IMDG). Use of IMDG architectures has been key to handling today’s web-scale loads because it eliminates database latency by storing important and frequently access data in memory instead of on disk. The CloudTran product lets developers easily use an IMDG for full ACID-compliant transactions without having to be concerned about the location or spread of data. The system has its own implementation of fast, scalable distributed transactions that does NOT depend on XA protocols but still guarantees all ACID properties. Plus, CloudTran asynchronously replicates data going into the IMDG to back-end datastores and back-up data centers, again ensuring ACID properties. CloudTran can be accessed through Java Persistence API (JPA via TopLink Grid) and now, through a new Low-Level API, or LLAPI. This is ideal for use in SOA applications that need data reliability, high availability, performance, and scalability. Still in limited beta release, the LLAPI gives developers the ability to use standard put/remove logic available in Coherence and then wrap logic with simple Spring annotations or XML+AspectJ to start transactions. An important feature of LLAPI is the ability to join transactions. This is a common outcome for SOA applications that need to reduce network traffic by aggregating data into single cache entries and then doing SOA service processing in the node holding the data. This results in the need to orchestrate transaction processing across multiple service calls. CloudTran has the capability to handle these “multi-client” transactions at speed with no loss in ACID properties. Developing software around an IMDG like Oracle Coherence is an important choice for today’s web-scale applications and services. But this introduces new architectural considerations to maintain scalability in light of increased network loads and data movement. Without using CloudTran, developers are faced with an incredibly difficult task to ensure data reliability, availability, performance, and scalability when working with an IMDG. Working with highly distributed data that is entirely volatile while stored in memory presents numerous edge cases where failures can result in data loss. The CloudTran product takes care of all of this, leaving developers with the confidence and peace of mind that all data is processed correctly. For those interested in evaluating the CloudTran product and IMDGs, take a look at this link for more information: http://www.CloudTran.com/downloadAPI.php, or, send your questions to [email protected].

  • Lagging digital tv over ethernet

    - by Steve
    I have a HD Home Run TV over ethernet device, which connects the aerial to my router, and from there the router connects to my PC over about 15m of 100Mbps ethernet cable. The TV output lags every second. It does not do so for a computer much closer to the router. It is odd to me that the network rate is around 7Mbps on a 100Mbps cable. I am not downloading or streaming anything else on the affected computer. Is this lag caused by the speed of the cable, the length of the cable, or interference on the cable? I am considering swapping the ethernet cable with shielded ethernet cable.

  • How can I get ssh-agent working over ssh and in tmux (on OS X)?

    - by Rich
    I have a private key set up for my github account, the passphrase to which is, I believe, stored in OS X's keychain. I certainly don't have to type it in when I open a terminal window and enter ssh [email protected]. However, when I'm running bash over an ssh session, or locally inside a tmux session, I have to type in the passphrase every single time I attempt to ssh to github. This question suggests that a similar problem exists with screen, but I don't really understand the issue well enough to fix it in tmux. There's also this page which includes a fairly complicated solution, but for zsh. EDIT: In response to @Mikel's answer, from a local terminal I get the following output: [~] $ echo $SSH_AUTH_SOCK /tmp/launch-S4HBD6/Listeners [~] $ ssh-add -l 2048 [my key fingerprint] /Users/richie/.ssh/id_rsa (RSA) [~] $ typeset -p SSH_AUTH_SOCK declare -x SSH_AUTH_SOCK="/tmp/launch-S4HBD6/Listeners" Whereas over ssh or in tmux I get: [~] $ echo $SSH_AUTH_SOCK [~] $ ssh-add -l Could not open a connection to your authentication agent. [~] $ typeset -p SSH_AUTH_SOCK bash: typeset: SSH_AUTH_SOCK: not found echo $SSH_AGENT_PID returns nothing whatever shell I run it from.

  • How to extract jpegs from a video file using ffmpeg

    - by Andrew Simpson
    I am using C# and ffmpeg. In this scenario I have 279 individual jpegs and i have used ffmpeg to create a AVI file from these images on my client. CMD Line: -f image2 -r 10 -i "C:\000EC902F17F\img%05d.jpg" -s 352x288 -y "C:\1\test.avi" I then upload to my server. CMD Line: -i c:\1\1.avi c:\1\img-%05d.jpg I then extract jpegs from the AVI file. I get 265 jpegs back. Obviously ffmpeg is dropping these frames (most probable) when the avi is 1st created. Is there a way to 'force' to encode using ALL the images I have? Thanks. PS I did not specify any command line option other than the size of the video output. As far as I am aware if none are specified then ffmpeg automatically chooses the best ones?

  • Microsoft and Application Architectures

    Microsoft has dealt with several kinds of application architectures to include but not limited to desktop applications, web applications, operating systems, relational database systems, windows services, and web services. Because of the size and market share of Microsoft, virtually every modern language works with or around a Microsoft product. Some of the languages include: Visual Basic, VB.Net, C#, C++, C, ASP.net, ASP, HTML, CSS, JavaScript, Java and XML. From my experience, Microsoft strives to maintain an n-tier application standard where an application is comprised of multiple layers that perform specific functions, for example: presentation layer, business layer, data access layer are three general layers that just about every formally structured application contains. The presentation layer contains anything to do with displaying information to the screen and how it appears on the screen. The business layer is the middle man between the presentation layer and data access layer and transforms data from the data access layer in to useable information to be stored later or sent to an output device through the presentation layer. The data access layer does as its name implies, it allows the business layer to access data from a data source like MS SQL Server, XML, or another data source. One of my favorite technologies that Microsoft has come out with recently is the .Net Framework. This framework allows developers to code an application in multiple languages and compiles them in to one intermediate language called the Common Language Runtime (CLR). This allows VB and C# developers to work seamlessly together as if they were working in the same project. The only real disadvantage to using the .Net Framework is that it only natively runs on Microsoft operating systems. However, Microsoft does control a majority of the operating systems currently installed on modern computers and servers, especially with personal home computers. Given that the Microsoft .Net Framework is so flexible it is an ideal for business to develop applications around it as long as they wanted to commit to using Microsoft technologies and operating systems in the future. I have been a professional developer for about 9+ years now and have seen the .net framework work flawlessly in just about every instance I have used it. In addition, I have used it to develop web applications, mobile phone applications, desktop applications, web service applications, and windows service applications to name a few.

  • Computer cables explained

    - by Robert English
    I've noticed lately that places to learn about both power supply cables and also peripherals and fans aren't that easy to find. There's very little information available that gives detailed explanations of what cables are used inside a computer. What I found was very dated and often lacked detailed explanations. For someone planning out their first build it would be great way for this to be explained all in one place, like here! Important things to know about cables and connections in a computer? What are their names? Where do they connect to and why? What typical Voltages do they output? Changing Voltages for Overclocking? Please refernce PSU cables(Full modular, Modular and Non-Modular,24-pin, 20+4-pin etc), SATA(I, II, III), Molex etc. EDIT: Forgot to mention any information about PSU rails would also be appreciated :)

  • Is code like this a "train wreck" (in violation of Law of Demeter)?

    - by Michael Kjörling
    Browsing through some code I've written, I came across the following construct which got me thinking. At a first glance, it seems clean enough. Yes, in the actual code the getLocation() method has a slightly more specific name which better describes exactly which location it gets. service.setLocation(this.configuration.getLocation().toString()); In this case, service is an instance variable of a known type, declared within the method. this.configuration comes from being passed in to the class constructor, and is an instance of a class implementing a specific interface (which mandates a public getLocation() method). Hence, the return type of the expression this.configuration.getLocation() is known; specifically in this case, it is a java.net.URL, whereas service.setLocation() wants a String. Since the two types String and URL are not directly compatible, some sort of conversion is required to fit the square peg in the round hole. However, according to the Law of Demeter as cited in Clean Code, a method f in class C should only call methods on C, objects created by or passed as arguments to f, and objects held in instance variables of C. Anything beyond that (the final toString() in my particular case above, unless you consider a temporary object created as a result of the method invocation itself, in which case the whole Law seems to be moot) is disallowed. Is there a valid reasoning why a call like the above, given the constraints listed, should be discouraged or even disallowed? Or am I just being overly nitpicky? If I were to implement a method URLToString() which simply calls toString() on a URL object (such as that returned by getLocation()) passed to it as a parameter, and returns the result, I could wrap the getLocation() call in it to achieve exactly the same result; effectively, I would just move the conversion one step outward. Would that somehow make it acceptable? (It seems to me, intuitively, that it should not make any difference either way, since all that does is move things around a little. However, going by the letter of the Law of Demeter as cited, it would be acceptable, since I would then be operating directly on a parameter to a function.) Would it make any difference if this was about something slightly more exotic than calling toString() on a standard type? When answering, do keep in mind that altering the behavior or API of the type that the service variable is of is not practical. Also, for the sake of argument, let's say that altering the return type of getLocation() is also impractical.

  • How to tell if OpenGL is really working in Ubuntu 10.04

    - by Jonathan
    I have a lenovo S9e running Intel integrated graphics. Here is my lspci output related to the graphics: 00:02.1 Display controller: Intel Corporation Mobile 945GM/GMS/GME, 943/940GML Express Integrated Graphics Controller (rev 03) Subsystem: Lenovo Device 3870 Flags: bus master, fast devsel, latency 0 Memory at f0580000 (32-bit, non-prefetchable) [size=512K] Capabilities: [d0] Power Management version 2 I want to know how I can make sure OpenGL support is running in full on an Ubuntu 10.04 installation. I have a few hints to think that it is not: The "Desktop Effects" will not load Apps such as stardock, when attempting to use OpenGL rendering, will display black boxes instead of transparency In the games Pioneers, the number-tile icons are suspiciously just black circles Windows games running with Wine will only support software rendering, not hardware rendering When I boot into a Knoppix LiveCD, the desktop effects do work, splendidly, meaning compiz detects my computer as capable. My problem with troubleshooting is that Canonical has basically eliminated the conf-file-based mechanism of X11 as far as I can tell, thus making it even harder to ensure graphics modules are loading properly. How do I debug and test OpenGL on m Ubuntu 10.04 installation?

  • iptables ACCEPT policy

    - by kamae
    In Redhat EL 6, iptables INPUT policy is ACCEPT but INPUT chain has REJECT entry in the end. /etc/syconfig/iptables is as below: *filter :INPUT ACCEPT [0:0] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [0:0] -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT -A INPUT -p icmp -j ACCEPT -A INPUT -i lo -j ACCEPT -A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT -A INPUT -j REJECT --reject-with icmp-host-prohibited -A FORWARD -j REJECT --reject-with icmp-host-prohibited COMMIT Do you know why the policy is ACCEPT not DROP? I think setting DROP policy is safer than ACCEPT in case to make mistake in the chain. Actually the policy is not applied to any packet: # iptables -L -v Chain INPUT (policy ACCEPT 0 packets, 0 bytes)

  • Missing disk space in Windows XP

    - by Jørn Schou-Rode
    On my mother's Lenovo laptop, Windows XP claims that the hard drive is almost full. According to the properties window, 52.7 out of 55.2 GB is in use: By deleting temp files from Internet Explorer, System Restore, Recycle bin, Windows Update, System Cleanup, I managed to free up about one GB. That's still 50 GB in use, which still is a lot more than I expected. Hence, I gave good old WinDirStat a spin, and here's the output: It might be hard to read here, but the first line says that the total amount of disk space in use on drive C is 24.3 GB. So Windows claims usage of 52.7 GB and WinDirStat can only account for 24.3 GB. Where is the other half of that disk space being used? I hope someone has an answer, or some tricks or tips to do further research. UPDATE: The laptop in question has an SSD hard drive. I am aware that these disk (at least the earlier ones) have a limited life-time. Could the symptoms described be caused by wear and tear on the SSD?

  • free Raw-File Converter/Editor

    - by RCIX
    I have RAW files output by a program with a specific set of properties (Photoshop RAW, 16 bits, IBM PC byte order, no header, 1 non-interleaved channel, variable sizes like 257X257 or 129X513); does anyone know of a free tool that will allow me to convert to and from this format, and possibly do basic editing (selection, copy/paste, rotation of selection)? I've tried Picasa, XNView, and Paint Shop Pro 7 and none of them work properly. The closest i get is Paint Shop Pro which will at least make a serviceable attempt to open these files but i can't set all of the proper settings. XNView just might be able to edit it if i can figure out how to change the open settings for a particular raw file. So my questions at current are: how do i tell XNView to open a raw file a particular way? Failing that, is there any free tool that can open Photoshop-RAW files with the above settings (that's not photoshop)? If it helps, i'm trying to import/export/edit hieghtmap data for maps for Supreme Commander.

  • PHP Script causing high CPU

    - by user20996
    I have a website which is causing me a major headache. There is one PHP script which is using far to much CPU, this only seem to happen when bots hit the site, I dont want to block all the bots because we need them. I have the the process manager output: Pid Owner Priority CPU % Memory % Command 16943 (Trace) (Kill) specialone 0 99.4 1.0 /usr/bin/php /var/www/specialone/page.php I ran strace -p 16943 on the process but it comes up with nothing. We have 2GB of RAM and the php memory_limit is set to 128M which should be enough. The trouble I have is the PHP code is a Framework and the culprit page.php pulls in a lot of other PHP files so I cant debug the PHP. Is there any way of finding out what the script is doing when its using so much CPU which will help me solve it?

  • 11.10 liveCD black screen

    - by Shaun Killingbeck
    Attempting to install/try ubuntu 11.10 on my new laptop, using a liveCD (and tried USB). I get the purple screen (with the man/keyboard at the bottom) and after that the screen flashes bright white before going black. Ubuntu continues to load in the background, with login sound etc but the screen is off. I have tried as many different solutions as I could find including: using nomodestep, xforcevesa, i915.modeset=0 in boot options (seperately): varying consequences, but either I end up at a blinking cursor with no prompt, a command line (startx fails: no screen found), or the original blank screen again Tried booting from VirtualBox - it crashes at the same place the screen would go blank when using a CD/USB tried 11.04: I don't have this problem BUT when trying to install, I get a ubi-partman error 141 (possibly down to the three partitions that came on my laptop... not sure why HP needed there own separate partition for HP Tools...) Model: HP Pavillion DV6 6B08SA Processor: AMD Quad-Core A6-3410MX APU with Radeon HD 6545G2 Dual Graphics (1.6 GHZ 4 MB L2 cache ) Chipset: AMD RS880M Any help would be greatly appreciated. I just want to be able to partition the drive and install Ubuntu. I'm assuming the issue is graphics card related, although I have no confirmation of that. I have caught a glimpse of some output to do with pulseaudio and [fail], but I can't imagine why that would cause a screen problem and the sound definitely works anyway.

  • Commands don't have permission when using absplute path

When running sudo -u deluge id, I get output uid=113(deluge) gid=124(deluge) skupiny=124(deluge) which shows that user deluge is indeed in group deluge. Also, the behavior was the same when I gave the permissions also to user deluge not just group deluge. When executing as non-system user, it does work. The reason that I want to use absolute paths is that I am using automatically triggered post-download script which extracts some files into the folder. I have spent way too many hours to solve this problem myself. mkdir isn't the only command that fails, touch is doing the same thing, so I suspect that it's not mkdir's fault. If you need more info, I will try to put it in here, just ask. Thanx in advance.

  • TDD with SQL and data manipulation functions

    - by Xophmeister
    While I'm a professional programmer, I've never been formally trained in software engineering. As I'm frequently visiting here and SO, I've noticed a trend for writing unit tests whenever possible and, as my software gets more complex and sophisticated, I see automated testing as a good idea in aiding debugging. However, most of my work involves writing complex SQL and then processing the output in some way. How would you write a test to ensure your SQL was returning the correct data, for example? Then, say if the data wasn't under your control (e.g., that of a 3rd party system), how can you efficiently test your processing routines without having to hand write reams of dummy data? The best solution I can think of is making views of the data that, together, cover most cases. I can then join those views with my SQL to see if it's returning the correct records and manually process the views to see if my functions, etc. are doing what they're supposed to. Still, it seems excessive and flakey; particularly finding data to test against...

Using event markers enables GoldenGate processes to take a defined action based on an event in the data stream. This feature within Oracle GoldenGate simplifies methods to embed specific custom processing in the areas of error handling, alerts, and notification. The event marker system effectively allows for DML driven workflows to be created within GoldenGate and enables customers to craft non-standard processing based on special events. There are a number of supported event actions including: trace, log, checkpoint before, suspend, abort, and several others. With 11gR1 events can now be triggered by DDL operations, plus variables can be passed in and out of the system to shell scripts. Some good use cases for this feature are Automatic switchover to the secondary system during planned outages Better monitoring over source systems’ performance and automated switchover to the standby system in case of an outage with the primary system Automatic switchover from initial load to changed data movement Automatic synchronization of any type of batch processing taking place on both the source and target databases for database consistency Automatic stoppage of the Delivery module to allow end-of-day reporting Finding, tracking, and reporting on transactions that are of interest including the ones that do not have primary keys or transaction record numbers If you would like to see a demo, please visit our youtube channel (http://youtube.com/oraclegoldengate)  To learn more about the new features of Oracle GoldenGate 11gR2 and to ask questions to the PM team, please join us on September 12th  8am or 10am PST for our live webcast.

  • sudo prompts for password over ssh

    - by Joe Watkins
    I have sudo set up for a shell script as follows on "hostname" (sudo -l output): (suser) NOPASSWD: /path/script* sudoers content is: myuser ALL=(suser) NOPASSWD: /path/script* this works fine, so I can run the following, logged in locally on hostname, without need for password: sudo -u suser /path/script however, when I use ssh (with keys set up, so no password require) to login and run, as follows: ssh hostname sudo -u suser /path/script I get prompted for a password, and when the password is entered I get: Sorry, user myuser is not allowed to execute '/path/script' as suser on hostname. Why? NB the following does not prompt for password at any point: $ ssh hostname $ sudo -u suser /path/script
