• Certificate Revocation checking affecting system performance [migrated]

  - by Colm Clarke

  I have a .NET 3.5 desktop application that had been showing periodic slow downs in functionality whenever the test machine it was on was out of the office. I managed to replicate the error on a machine in the office without an internet connection, but it was only when i used ANTS performance profiler that i got a clearer picture of what was going on. In ANTS I saw a "Waiting for synchronization" taking up to 16 seconds that corresponded to the delay I could see in the application when NHibernate tried to load the System.Data.SqlServerCE.dll assembly. If I tried the action again immediately it would work with no delay but if I left it for 5 minutes then it would be slow to load again the next time I tried it. From my research so far it appears to be because the SqlServerCE dll is signed and so the system is trying to connect to get the certificate revocation lists and timing out. Disabling the "Automatically detect settings" setting in the Internet Options LAN settings makes the problem go away, as does disabling the "Check for publishers certificate revocation". But the admins where this application will be deployed are not going to be happy with the idea of disabling certificate checking on a per machine or per user basis so I really need to get the application level disabling of the CRL check working. There is the well documented bug in .net 2.0 which describes this behaviour, and offers a possible fix with a config file element. <?xml version="1.0" encoding="utf-8"?> <configuration> <runtime> <generatePublisherEvidence enabled="false"/> </runtime> </configuration> This is NOT working for me however even though I am using .net 3.5. The SQLServerCE dll is being loaded dynamically by NHibernate and I wonder if the fact that it's dynamic could somehow be why the setting isn't working, but I don't know how I could check that. Can anyone offer suggestions as to why the config setting might not work? Or is there another way I could disable the check at the application level, perhaps a CAS policy setting that I can use to set an exception for the application when it's installed? Or is there something I can change in the application to up the trust level or something like that? I have also tried using to no advantage ServicePointManager.CheckCertificateRevocationList = false; http://rusanu.com/2009/07/24/fix-slow-application-startup-due-to-code-sign-validation/ I have also tried those registry settings out and unfortunately they didn't help. The dlls that appear to be the cause of the hold up are native SQL Server CE dlls, and looking at the stack traces in ProcMon mscorwks.dll doesn't appear to be involved even though the checks on crypto and cert registry keys are being done under the .NET application. It's definitely still something to do with publisher certificate checking because unticking "Check for publisher revocation certificate" still works but something odd is going on.

• Unable to install Konstruktor program

  - by George Barnick

  I've recently switched to Linux, having a good knowledge of how it works before switching, since I've had experience working with Ubuntu-based servers for several months. I've been trying to install a LEGO CAD program that I have found based on an open source library. Information on that is here. The program I'm looking at is called Konstruktor, and for the most part it should be working. One dependency however does not seem to be able to install. The missing dependency is "kdelibs5", which I know what it is and what it's for, but can't get it to install. When trying to install, I get this error: george@GEORGE-PC:~$ sudo apt-get install kdelibs5 Reading package lists... Done Building dependency tree Reading state information... Done Package kdelibs5 is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package 'kdelibs5' has no installation candidate When trying to install the proper package of Konstruktor for my system, I get this error: george@GEORGE-PC:~$ sudo dpkg -i '/home/george/Downloads/konstruktor_0.9-beta1-2_amd64.deb' Selecting previously unselected package konstruktor.

I tried the package "kdelibs5-dev", which installed fine, but "kdelibs5" won't, and Konstruktor still won't install. I am on Ubuntu 13.10 with GNOME shell on amd64 architecture. Any help would be much appreciated. (originally posted my issue here) Thanks ahead of time.

• July, the 31 Days of SQL Server DMO’s – Day 25 (sys.dm_db_missing_index_details)

  - by Tamarick Hill

  The sys.dm_db_missing_index_details Dynamic Management View is used to return information about missing indexes on your SQL Server instances. These indexes are ones that the optimizer has identified as indexes it would like to use but did not have. You may also see these same indexes indicated in other tools such as query execution plans or the Database tuning advisor. Let’s execute this DMV so we can review the information it provides us. I do not have any missing index information for my AdventureWorks2012 database, but for the purposes of illustrating the result set of this DMV, I will present the results from my msdb database. SELECT * FROM sys.dm_db_missing_index_details The first column presented is the index_handle which uniquely identifies a particular missing index. The next two columns represent the database_id and the object_id for the particular table in question. Next is the ‘equality_columns’ column which gives you a list of columns (comma separated) that would be beneficial to the optimizer for equality operations. By equality operation I mean for any queries that would use a filter or join condition such as WHERE A = B. The next column, ‘inequality_columns’, gives you a comma separated list of columns that would be beneficial to the optimizer for inequality operations. An inequality operation is anything other than A = B. For example, “WHERE A != B”, “WHERE A > B”, “WHERE A < B”, and “WHERE A <> B” would all qualify as inequality. Next is the ‘included_columns’ column which list all columns that would be beneficial to the optimizer for purposes of providing a covering index and preventing key/bookmark lookups. Lastly is the ‘statement’ column which lists the name of the table where the index is missing. This DMV can help you identify potential indexes that could be added to improve the performance of your system. However, I will advise you not to just take the output of this DMV and create an index for everything you see. Everything listed here should be analyzed and then tested on a Development or Test system before implementing into a Production environment. For more information on this DMV, please see the below Books Online link: http://msdn.microsoft.com/en-us/library/ms345434.aspx Follow me on Twitter @PrimeTimeDBA

• A* navigational mesh path finding

  - by theguywholikeslinux

  So I've been making this top down 2D java game in this framework called Greenfoot [1] and I've been working on the AI for the guys you are gonna fight. I want them to be able to move around the world realistically so I soon realized, amongst a couple of other things, I would need some kind of pathfinding. I have made two A* prototypes. One is grid based and then I made one that works with waypoints so now I need to work out a way to get from a 2d "map" of the obstacles/buildings to a graph of nodes that I can make a path from. The actual pathfinding seems fine, just my open and closed lists could use a more efficient data structure, but I'll get to that if and when I need to. I intend to use a navigational mesh for all the reasons out lined in this post on ai-blog.net [2]. However, the problem I have faced is that what A* thinks is the shortest path from the polygon centres/edges is not necessarily the shortest path if you travel through any part of the node. To get a better idea you can see the question I asked on stackoverflow [3]. I got a good answer concerning a visibility graph. I have since purchased the book (Computational Geometry: Algorithms and Applications [4]) and read further into the topic, however I am still in favour of a navigational mesh (See "Managing Complexity" [5] from Amit’s Notes about Path-Finding [6]). (As a side note, maybe I could possibly use Theta* to convert multiple waypoints into one straight line if the first and last are not obscured. Or each time I move back check to the waypoint before last to see if I can go straight from that to this) So basically what I want is a navigational mesh where once I have put it through a funnel algorithm (e.g. this one from Digesting Duck [7]) I will get the true shortest path, rather than get one that is the shortest path following node to node only, but not the actual shortest given that you can go through some polygons and skip nodes/edges. Oh and I also want to know how you suggest storing the information concerning the polygons. For the waypoint prototype example I made I just had each node as an object and stored a list of all the other nodes you could travel to from that node, I'm guessing that won't work with polygons? and how to I tell if a polygon is open/traversable or if it is a solid object? How do I store which nodes make up the polygon? Finally, for the record: I do want to programme this by myself from scratch even though there are already other solutions available and I don't intend to be (re) using this code in anything other than this game so it does not matter that it will inevitably be poor quality. http://greenfoot.org http://www.ai-blog.net/archives/000152.html http://stackoverflow.com/q/7585515/ http://www.cs.uu.nl/geobook/ http://theory.stanford.edu/~amitp/GameProgramming/MapRepresentations.html http://theory.stanford.edu/~amitp/GameProgramming/ http://digestingduck.blogspot.com/2010/03/simple-stupid-funnel-algorithm.html

• Fluid VS Responsive Website Development Questions

  - by Aditya P

  As I understand these form the basis for targeting a wide array of devices based on the browser size, given it would be a time consuming to generate different layouts targeting different/specific devices and their resolutions. Questions: Firstly right to the jargon, is there any actual difference between the two or do they mean the same? Is it safe to classify the current development mainly a html5/css3 based one? What popular frameworks are available to easily implement this? What testing methods used in this regard? What are the most common compatibility issues in terms of different browser types? I understand there are methods like this http://css-tricks.com/resolution-specific-stylesheets/ which does this come under?. Are there any external browser detection methods besides the API calls specific to the browser that are employed in this regard? Points of interest [Prior Research before asking these questions] Why shouldn't "responsive" web design be a consideration? Responsive Web Design Tips, Best Practices and Dynamic Image Scaling Techniques A recent list of tutorials 30 Responsive Web Design and Development Tutorials by Eric Shafer on May 14, 2012 Update Ive been reading that the basic point of designing content for different layouts to facilitate a responsive web design is to present the most relevant information. now obviously between the smallest screen width and the highest we are missing out on design elements. I gather from here http://flashsolver.com/2012/03/24/5-top-commercial-responsive-web-designs/ The top of the line design layouts (widths) are desktop layout (980px) tablet layout (768px) smartphone layout – landscape (480px) smartphone layout – portrait (320px) Also we have a popular responsive website testing site http://resizemybrowser.com/ which lists different screen resolutions. I've also come across this while trying to find out the optimal highest layout size to account for http://stackoverflow.com/questions/10538599/default-web-page-width-1024px-or-980px which brings to light seemingly that 1366x768 is a popular web resolution. Is it safe to assume that just accounting for proper scaling from width 980px onwards to the maximum size would be sufficient to accommodate this? given we aren't presenting any new information for the new size. Does it make sense to have additional information ( which conflicts with purpose of responsive web design) to utilize the top size and beyond?

• Is there a better term than "smoothness" or "granularity" to describe this language feature?

  - by Chris Stevens

  One of the best things about programming is the abundance of different languages. There are general purpose languages like C++ and Java, as well as little languages like XSLT and AWK. When comparing languages, people often use things like speed, power, expressiveness, and portability as the important distinguishing features. There is one characteristic of languages I consider to be important that, so far, I haven't heard [or been able to come up with] a good term for: how well a language scales from writing tiny programs to writing huge programs. Some languages make it easy and painless to write programs that only require a few lines of code, e.g. task automation. But those languages often don't have enough power to solve large problems, e.g. GUI programming. Conversely, languages that are powerful enough for big problems often require far too much overhead for small problems. This characteristic is important because problems that look small at first frequently grow in scope in unexpected ways. If a programmer chooses a language appropriate only for small tasks, scope changes can require rewriting code from scratch in a new language. And if the programmer chooses a language with lots of overhead and friction to solve a problem that stays small, it will be harder for other people to use and understand than necessary. Rewriting code that works fine is the single most wasteful thing a programmer can do with their time, but using a bazooka to kill a mosquito instead of a flyswatter isn't good either. Here are some of the ways this characteristic presents itself. Can be used interactively - there is some environment where programmers can enter commands one by one Requires no more than one file - neither project files nor makefiles are required for running in batch mode Can easily split code across multiple files - files can refeence each other, or there is some support for modules Has good support for data structures - supports structures like arrays, lists, and especially classes Supports a wide variety of features - features like networking, serialization, XML, and database connectivity are supported by standard libraries Here's my take on how C#, Python, and shell scripting measure up. Python scores highest. Feature C# Python shell scripting --------------- --------- --------- --------------- Interactive poor strong strong One file poor strong strong Multiple files strong strong moderate Data structures strong strong poor Features strong strong strong Is there a term that captures this idea? If not, what term should I use? Here are some candidates. Scalability - already used to decribe language performance, so it's not a good idea to overload it in the context of language syntax Granularity - expresses the idea of being good just for big tasks versus being good for big and small tasks, but doesn't express anything about data structures Smoothness - expresses the idea of low friction, but doesn't express anything about strength of data structures or features Note: Some of these properties are more correctly described as belonging to a compiler or IDE than the language itself. Please consider these tools collectively as the language environment. My question is about how easy or difficult languages are to use, which depends on the environment as well as the language.

• How do you structure computer science University notes?

  - by Sai Perchard

  I am completing a year of postgraduate study in CS next semester. I am finishing a law degree this year, and I will use this to briefly explain what I mean when I refer to the 'structure' of University notes. My preferred structure for authoring law notes: Word Two columns 0.5cm margins (top, right, bottom, middle, left) Body text (10pt, regular), 3 levels of headings (14/12/10pt, bold), 3 levels of bulleted lists Color A background for cases Color B background for legislation I find that it's crucial to have a good structure from the outset. My key advice to a law student would be to ensure styles allows cases and legislation to be easily identified from supporting text, and not to include too much detail regarding the facts of cases. More than 3 levels of headings is too deep. More than 3 levels of a bulleted list is too deep. In terms of CS, I am interested in similar advice; for example, any strategies that have been successfully employed regarding structure, and general advice regarding note taking. Has latex proved better than Word? Code would presumably need to be stylistically differentiated, and use a monospaced font - perhaps code could be written in TextMate so that it could be copied to retain syntax highlighting? (Are notes even that useful in a CS degree? I am tempted to simply use a textbook. They are crucial in law.) I understand that different people may employ varying techniques and that people will have personal preferences, however I am interested in what these different techniques are. Update Thank you for the responses so far. To clarify, I am not suggesting that the approach should be comparable to that I employ for law. I could have been clearer. The consensus so far seems to be - just learn it. Structure of notes/notes themselves are not generally relevant. This is what I was alluding to when I said I was just tempted to use a textbook. Re the comment that said textbooks are generally useless - I strongly disagree. Sure, perhaps the recommended textbook is useless. But if I'm going to learn a programming language, I will (1) identify what I believe to be the best textbook, and (2) read it. I was unsure if the combination of theory with code meant that lecture notes may be a more efficient way to study for an exam. I imagine that would depend on the subject. A subject specifically on a programming language, reading a textbook and coding would be my preferred approach. But I was unsure if, given a subject containing substantive theory that may not be covered in a single textbook, people may have preferences regarding note taking and structure.

• This Task Is Currently Locked by a Running Workflow and Cannot Be Edited

  - by Jayant Sharma

  Problem: In SharePoint Workflow, "This task is currently locked by a running workflow and cannot be edited" is the common exception, that we face. Solution: Generally this exception occurs 1.  when the number of items in the Task List gets highThis exception says that the workflow is not able to deliver the all the events at a given time and so the tasks get locked.  Out Of Box, the default event delivery throttle value is 15.  Event delivery throttle value Specifies the number of workflows that can be processed at the same time across all front-end Web serverslook at following link.(http://blogs.msdn.com/b/vincent_runge/archive/2008/09/16/about-the-workflow-eventdelivery-throttle-parameter.aspx)If the value returned by query is superior to the throttle (15 by default), any new workflow event will not be processed immediately. so we need to change it by stsadm command like...stsadm -o setproperty -pn workflow-eventdelivery-throttle -pv "20"(http://technet.microsoft.com/en-us/library/cc287939(office.12).aspx) 2. When we modify a Workflow Task from Custom TaskEdit Page.   when we try to modify the workflow task from outside workflow default Page, like custom workflow taskedit page. then is exception occurs.suppose we have custom task edit page with dropdown  and values are submitted/ Progress/ completed etc and we want to complete task from here. it will throw exception on SPWorkflowTask.AlterTask method, which changes the TaskStatus.When I debug, to find the root cause I actully found that the workflow is not locked. The InternalState flag of the workflow does not include the Locked flag bits(http://msdn.microsoft.com/en-us/library/dd928318(v=office.12).aspx) When I found this link http://geek.hubkey.com/2007/09/locked-workflow.htmlIt is exactly what I wanted. It says that "when the WorkflowVersion of the task list item is not equal to 1" then the error occurs. The solution that is propsed here works fantastically if ((int)task[SPBuiltInFieldId.WorkflowVersion] != 1){    SPList parentList = task.ParentList.ParentWeb.Lists[new Guid(task[SPBuiltInFieldId.WorkflowListId].ToString())];    SPListItem parentItem = parentList.Items.GetItemById((int)task[SPBuiltInFieldId.WorkflowItemId]);    SPWorkflow workflow = parentItem.Workflows[new Guid(task[SPBuiltInFieldId.WorkflowInstanceID].ToString())];    if (!workflow.IsLocked)    {       task[SPBuiltInFieldId.WorkflowVersion] = 1;       task.SystemUpdate();      break;    }} It will reset the workflow version to 1 again.Conclusion: This Exception is completely confusing. So, we need to find at first whether our workflow is really locked or not. If it is really locked then use 1st method. If not, then check the workflow version and set it to 1 again.Jayant Sharma

• Scan Your Thumb Drive for Viruses from the AutoPlay Dialog

  - by Mysticgeek

  It’s always a good idea to scan someone’s flash drive for viruses when you use it on your PC. Today we look at how to use Microsoft Security Essentials to scan thumb drives via the AutoPlay dialog. Editor Note: This technique was created by our friend Ramesh Srinivasan from the winhelponline tech blog. If you haven’t done so already, download and install Microsoft Security Essentials (link below), which has earned the How-To Geek official endorsement. Next download the mseautoplay.zip (link below). Unzip the file to view its contents. Then move the msescan.vbs script file into the Windows directory. Next double-click on the mseautoplay.reg file… Click Yes to the warning dialog window asking if you’re sure you want to add to the registry. After it’s added you’ll get a confirmation message…click OK. Now when you pop in a thumb drive, when AutoPlay comes up you will have the options to scan it with MSE first. MSE starts the scan of the thumb drive…   You can use this to scan any removable media. Here is an example of the ability to scan a DVD with MSE before opening any files. You can also go into Control Panel and set it as a default option of AutoPlay. Open Control Panel, View by Large icons, and click on AutoPlay. Notice that now when you go to change the default options for different types of media, Scanning with MSE is now included in the dropdown lists. Remove Settings If you want to remove the MSE AutoPlay Handler, Ramesh was kind enough to create an undo registry file. Double-click on undo.reg from the original MSE AutoPlay folder and click yes to the message to remove the setting.   Then you will need to go into the Windows directory and manually delete the msescan.vbs script file. This is an awesome trick which will allow you to scan your thumb drives and other removable media from the AutoPlay dialog. We tested it out on XP, Vista, and Windows 7 and it works perfectly on each one.

• SharePoint 2010 Data Retrival Techinques

  - by Jayant Sharma

  In SharePoint, we have two options to perform CRUD operation.1. using server side code2. using client side codeusing server side code, we have 1. CAML2. LINQusing client side code, we have 1. Client Object Model    1.1.      Managed Client Object Model     1.2.     Silverlight Client Object Model    1.3.     ECMA Client Object Model2. SharePoint Web Services3. ADO Data Service (based on REST Web Services)4. Using RPC Call (owssvr.dll)Which and when these options are used depend upon requirements. Every options are certain advantages and disadvantages. So, before start development of any new sharepoint project, it is important to understand the limitations of different methods.Server Object Model is used when our application is host on the same server on which sharepoint is installed. while Client Side code is used to access sharepoint from client system. In SharePoint 2010 specially Client Object Model (COM) are introduced to perform the sharepoint operations from client system. Advantage of CAML:    -  It is fast.    -  Can be use it from all kind of technology like Silverlight, or Jquery    -  You can use U2U CAML Query builder to generate CAML Query.Disadvantage Of CAML:    - Error Prone, as we can detect the error only at runtimeAdvantage of LINQ:    -  Object Oriented technique (Object Relation Model)    -  LINQ  to SharePoint provider are working with Strongly Type List Item Objects, So intellisence are present at runtime    -  No need of knowledge of CAML    -  Less Error Prone as it as it uses C# syntex.    -  You can compare two Fields of SharePoint ListDisadvantage Of LINQ:    -  List Attachment is not supported in SPMetal Tool    -  Created By, Created, Modified and Modified By Fields are not created by SPMetal Tool.    -  Custom fields are not created by SPMetal Tools    -  External Lists are not supported    -  Though at backend LINQ genenates CAML Query so it is slower than directly using CAML in Code.  Advantage of Client Object Model    -  Used to access sharepoint from client system    -  No WebServer is required at Client End    - Can use Silverlight and JavaScripts to make better and fast User experienceDisadvantage of Client Object Model    -  You cannot use RunwithEleveatedPrivilege    - Cross Site Collection query are not possible    - Lesser API's are availableADO.Net Data Services:    -  Only List based operations are possible, other type of operations are not possible.SharePoint Web Services and RPC Call:    - Previously it was used in SharePoint 2007 but after the introduction  of Client Object Model,  Microsoft recommends not to use Web Services to fetch data from SharePoint. In SharePoint 2010 it is avaliable only for backward compatibility.Ref: http://msdn.microsoft.com/en-us/library/ee539764Jayant Sharma

• Oracle WebCenter: Social Networking & Collaboration

  - by kellsey.ruppel(at)oracle.com

  We’ve talked in previous weeks about the key goals of the new release of WebCenter are providing a Modern User Experience, unparalleled Application Integration, converging all the best of the existing portal platforms into WebCenter and delivering a Common User Experience Architecture.  We’ve provided an overview of Oracle WebCenter and discussed some of the other key goals in previous weeks, and this week, we’ll focus on how the new release of Oracle WebCenter provides unprecedented Social Networking and Collaboration.We recently talked with Carin Chan, Principal Product Manager at Oracle, around the topic of Social Networking and Collaboration. In today’s work environment, employees have come to expect social and collaborative services to augment their work environment. Whether it is to post a blog or to poll fellow coworkers, employees expect and demand access to highly integrated, collaborative work environments that allow them to quickly contribute at work -- whether it is to make informed decisions, contribute on projects, or share knowledge.Social and collaborative services from Oracle WebCenter add an immeasurable amount of value to achieving a modern user experience. Oracle WebCenter Services provides rich and comprehensive social computing services that include services such as wikis, blogs, instant messaging, presence, activity streams and graphs, and polls/surveys that offer employees access to rich collaborative services to work efficiently.Employees can create pages or spaces that mix and match collaborative services while bringing in data from other applications to share with groups, teams, or organizations. These out of the box social and collaborative services include: People Connections and Activity Streams enable users to quickly assemble and visualize their social business networks and track user activities.Activity Graphs tracks all user activities in real-time and gathers intelligence about these users, their connections and the way they use information to make educated recommendations and provide on the spot information discovery.Wikis and blogs enable the community authoring of documents and sharing of ideas and also allow for the gathering of feedback and comments on those ideas.Tags and links allow users to easily mark, connect and share information with others.RSS feeds are available to track new or changed information related to discussion forums, processes or activities in an Oracle WebCenter environment.Discussion forums enable sharing of group knowledge and easy creation of communities around specific topics.Announcements allow you to manage and publish important news to your user base.Instant Messaging and Presence enable real-time awareness and communication with available users in the context of a business task.Web and Voice Conferencing enables real-time communication with internal and external business users.Lists provide a way to manage list data directly on the web as well as export and import it from and to Microsoft Excel.Oracle WebCenter Analytics provides comprehensive reporting metrics on activity and content usage within portals or composite applications.Activity Streams allow you to track activities and visualize your business networks.While being able to integrate into your portal deployment, these services are also integrated into how users are already working. This includes integration with software such as Microsoft Outlook, Microsoft Office and mobile devices such as the Apple iPhone. These services are just a tip of the iceberg regarding social and collaborative services that Oracle WebCenter has to offer your employees. Be sure to keep checking back this week for in future posts, we’ll delve deeper into a few of these collaborative services and discuss how a combination of collaborative services offer a better portal deployment to empower business users.

• Should I be put off a junior role that uses an online development test?

  - by Ninefingers

  I've applied for a junior development role, or rather been found by a recruiter looking for a developer. In order to get to a telephone interview stage I've been asked to sit one of those online coding assessments. This wasn't quite what I expected. I consider myself a fairly good developer for my age and experience, but I've no illusions about being Don Knuth or anything. The test was a series of incredibly obtuse questions asking about the results of various obscure evaluations. About 30 minutes in I was thinking to myself I hadn't intended to enter an obfuscated code contest/code golf exercise. After my last telephone interview I was asked to build something. I did. That seemed fair. Go away and work this out is more my in office experience of programming than "please evaluate this combination of lambdas, filters, maps, lists, tuples etc". So I'm a little put off, to be honest. I never claimed to know the language inside out or all the little corner cases. My questions, then: Should I be put off? Why? Why not? Are these kinds of tests what I should be expecting for junior roles? Should I learn stuff exam style? That seems to be the objective of these tests, for which you are timed and not supposed to use references or books? Normally, in the course of development I have a fairly good idea of basic types, rules, flow control and whatever. Occasionally I'll come up on something I need to use a regex for and have to go and remind myself of the exact piece of syntax I need if trying what I think should work doesn't. Or I'll come up against a module I've not used before and go and look it up. For example, if I wanted to write a server using sockets in C right now, I'd probably check the last piece of code I wrote doing that (and or the various books I have) and work from there. Chances are I probably couldn't do it exactly from scratch and from memory, although I can tell you you'd need a socket(), bind(), listen() and accept() call and you might also want select() depending on whether you intend to pthread_create or not. So I know what the calls are, but not their specific parameter list. What are your experiences if you are a recruiting manager? Are you after programmers who can quote you the API or do you not mind if your programmers have a few books on their desk and google function calls every so often?

• K2 4.5 Quick Thoughts

  I just finished attending a webcast on K2 4.5 and I thought Id share a few quick thoughts. Power User Story Improved Given it is just a presentation and I havent actually played with it, the story seemed improved and more believable that real world power users would be able to define workflows in SharePoint.  Power users who would be comfortable with Excel functions may be able to do some more worthwhile workflows since there is new support for inline functions and conditions.  The new SilverLight K2 designer seems pretty user friendly, though the dialog windows can really stack up which may get confusing.  I thought the neatest part was that the workflow can be defined just by starting with a SharePoint Lists settings which may be okay for some organizations and simpler workflows that dont need to define the workflow and push it through lots of testing in different environments.  The standalone K2 Studio is back.  In K2 2003 it was required because Visual Studio integration didnt exist.  Its back now for use by power users who need functionality up to the point of code.  Not sure if this Administration/Installation Installation is supposed to be simplified, with unattended install and other details I didnt catch.  Install and configuration has always seemed daunting to me so anything to improve that is good.  Related to that there is a new tool that is meant to help diagnose issues in your installation.  That may include figuring out missing permissions or services that arent running.  Also, now all K2 SharePoint features deployed as solutions. Dynamic SQL Service Broker Create a smart object to go against a table that you created, NOT the SmartBox.  This seems promising and something that maybe should have been there all along. Reference Event Allows you to call functionally that youve referenced, in the sample showing it was calling a web service that was referenced.  It seemed odd because it was really like writing code using dialogs (call constructor, set timeout, call web service method).  Seemed a little odd to me. Help We were reminded that help.k2.com site is newish site that is supposed to be the MSDN of K2 for partners and customers. VS 2010 Support Still no hard date on this, but what we were told is approximately 90 days after VS 2010 is officially released.Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• How to Assign a Default Signature in Outlook 2013

  - by Lori Kaufman

  If you sign most of your emails the same way, you can easily specify a default signature to automatically insert into new email messages and replies and forwards. This can be done directly in the Signature editor in Outlook 2013. We recently showed you how to create a new signature. You can also create multiple signatures for each email account and define a different default signature for each account. When you change your sending account when composing a new email message, the signature would change automatically as well. NOTE: To have a signature added automatically to new email messages and replies and forwards, you must have a default signature assigned in each email account. If you don’t want a signature in every account, you can create a signature with just a space, a full stop, dashes, or other generic characters. To assign a default signature, open Outlook and click the File tab. Click Options in the menu list on the left side of the Account Information screen. On the Outlook Options dialog box, click Mail in the list of options on the left side of the dialog box. On the Mail screen, click Signatures in the Compose messages section. To change the default signature for an email account, select the account from the E-mail account drop-down list on the top, right side of the dialog box under Choose default signature. Then, select the signature you want to use by default for New messages and for Replies/forwards from the other two drop-down lists. Click OK to accept your changes and close the dialog box. Click OK on the Outlook Options dialog box to close it. You can also access the Signatures and Stationery dialog box from the Message window for new emails and drafts. Click New Email on the Home tab or double-click an email in the Drafts folder to access the Message window. Click Signature in the Include section of the New Mail Message window and select Signatures from the drop-down menu. In the next few days, we will be covering how to use the features of the signature editor next, and then how to insert and change signatures manually, backup and restore your signatures, and modify a signature for use in plain text emails.

• Canonicalization of single, small pages like reviews or product categories [SEO]

  - by Valorized

  In general I pretty much like the idea of canonicalization. And in most cases, Google explains possible procedures in a clear way. For example: If I have duplicates because of parameters (eg: &sort=desc) it's clear to use the canonical for the site, provided the within the head-tag. However I'm wondering how to handle "small - no to say thin content - sites". What's my definition of a small site? An Example: On one of my main sites, we use a directory based url-structure. Let's see: example.com/ (root) example.com/category-abc/ example.com/category-abc/produkt-xy/ Moreover we provide on page, that includes all products example.com/all-categories/ (lists all products the same way as in the categories) In case of reviews, we use a similar structure: example.com/reviews/product-xy/ shows all review for one certain product example.com/reviews/product-xy/abc-your-product-is-great/ shows one certain review example.com/reviews/ shows all reviews for all products (latest first) Let's make it even more complicated: On every product site, there are the latest 2 reviews at the end of the page. So you see, a lot of potential duplicates. Q1: Should I create canonicals for a: example.com/category-abc/ to example.com/all-categories/ b: example.com/reviews/product-xy/abc-your-product-is-great/ to example.com/reviews/product-xy/ or to example.com/review/ or none of them? Q2: Can I link the collection of categories (all-categories/) and collection of all reviews (reviews/ and reviews/product-xy/) to the single category respectively to the single review. Example: example.com/reviews/ includes - let's say - 100 reviews. Can I somehow use a markup that tells search engines: "Hey, wait, you are now looking at a collection of 100 reviews - do not index this collection, you should rather prefer indexing every single review as a single page!". In HTML it might be something like that (which - of course - does not work, it's only to show you what I mean): <div class="review" rel="canonical" href="http://example.com/reviews/product-xz/abc-your-product-is-great/">HERE GOES THE REVIEW</div> Reason: I don't think it is a great user experience if the user searches for "your product is great" and lands on example.com/reviews/ instead of example.com/reviews/product-xy/abc-your-product-is-great/. On the first site, he will have to search and might stop because of frustration. The second result, however, might lead to a conversion. The same applies for categories. If the user is searching for category-Z, he might land on the all-categories page and he has to scroll down to the (last) category, to find what he searched for (Z). So what's best practice? What should I do? Thank you for your help!

• Tips On Using The Service Contracts Import Program

  - by LuciaC

  Prior to release 12.1 there was no supported way to import contracts into the EBS Service Contracts application - there were no public APIs nor contract load programs provided.  From release 12.1 onwards the 'Service Contracts Import Program' is provided to load service contracts into the application. The Service Contracts Import functionality is explained in How to Use the Service Contracts Import Program - Scope and Limitations (Doc ID 1057242.1).  This note includes an attached document which explains the program architecture, shows the Entity Relationship Diagram and details the interface table definitions. The Import program takes data from the interface tables listed below and populates the contracts schema tables:  OKS_USAGE_COUNTERS_INTERFACE OKS_SALES_CREDITS_INTERFACEOKS_NOTES_INTERFACEOKS_LINES_INTERFACEOKS_HEADERS_INTERFACEOKS_COVERED_LEVELS_INTERFACEThese interface tables must be loaded via a custom load program.The Service Contracts Import concurrent request is then submitted to create contracts from this legacy data. The parameters to run the Import program are:  Parameter Description  Mode Validate only, Import  Batch Number Batch_Id (unique id populated into the OKS_HEADERS_INTERFACE table)  Number of Workers Number of workers required (these are spawned as separate sub-requests)  Commit size Represents number of successfully processed contracts commited to database The program spawns sub-requests for the import worker(s) and the 'Service Contracts Import Report'.  The data is validated prior to import and into the Contracts tables and will report errors in the Service Contracts Import Report program output file (Import Execution Report).  Troubleshooting tips are provided in R12.1 - Common Service Contract Import Errors (Doc ID 762545.1); this document lists some, but not all, import errors.  The document will be updated over time.  Additional help is given in Debugging Tip for Service Contracts Import Errors (Doc ID 971426.1).After you successfully import contracts, you can purge the records from the interface tables by running the Service Contracts Import Purge concurrent program. Note that there is no supported way to mass delete data from the Contracts schema tables once they are populated, so data loaded by the Import program must be fully tested and verified before the program is run to load data into a Production system.A Service Contracts Import Test program has been provided which will take an existing contract in the application and load the interface tables using the data from that contract.  This can be used as an example for guidance on how to load the interface tables.  The Test program functionality is explained in How to Use the Service Contracts Test Import Program Provided in Release 12.1 (Doc ID 761209.1).  Note that the Test program has some limitations which do not apply to the full Import program and is not a supported program, it is simply a testing tool.
