• MySQL server stopped working after upgrade

• Exam 70-541 - TS: Microsoft Windows SharePoint Services 3.0 - Application Development

  - by DigiMortal

  Today I passed Microsoft exam 70-541: Microsoft Windows SharePoint Services 3.0 - Application Development. This exam gives you MCTS certificate. In this posting I will talk about the exam and also give some suggestions about books to read when preparing for exam. About exam This exam was good one I think. The questions were not hard and also not too easy. Just enough to make sure you really know what you do when working with SharePoint. Or at least to make sure you how things work. After couple of years active SharePoint coding this exam needs no additional preparation. The questions covered very different topics like alerts, features, web parts, site definitions, event receivers, workflows, web services and deployments. There are 59 questions in the exam (this information is available in internet) and you have time a little bit more than two hours. It took me about 40 minutes to get questions answered and reviewed. I strongly suggest you to study the parts of WSS 3.0 you don’t know yet and write some code to find out how to use these things through SharePoint API. Good reading For guys with less experience there are some good books to suggest. Take one or both of these books because there are no official study materials or training kits available for this exam. One of my colleagues who is less experienced than me suggested Inside Microsoft Windows SharePoint Services 3.0 by Ted Pattison and Daniel Larson. He told me that he found this book most useful for him to pass this exam.   When I started with SharePoint Services 3.0 my first book was Developer’s Guide To The Windows SharePoint Services v3 Platform by Todd C. Bleeker. It helped me getting started and later it was my main handbook for some time. Of course, there are many other good books and I suggest you to take what you find. Of course, before buying something I suggest you to discuss with guys who have read the book before. And make sure you mention that you are preparing for exam.   Conclusion If you are experienced SharePoint developer then this exam needs no preparation. Okay, some preparation is always good but if you don’t have time you are still able to pass this exam. If you are not experienced SharePoint developer then study before taking this exam – it is not easy stuff for novices. But if you pass this exam you can proudly say – yes, I know something about SharePoint! :)

• Backpacks and Booth Paint: TechEd 2012

  - by The Un-T Guy

  Arriving in the parking lot of the Orange County Convention Center, I immediately knew I was in the right place. As far as the eye could see, the acres of asphalt were awash in backpacks, quirky (to be kind) outfits, and bad haircuts. This was the place. This was Microsoft Mecca v2012 for geeks and nerds, the Central Florida event of the year, a gathering of high tech professionals whose skills I both greatly respect and, frankly, fear a little. I was wholly and completely out of element, a dork in a vast sea of geek jumbo. It like was wearing dockers and a golf shirt walking into a RenFaire, but one with really crappy costumes and no turkey legs...save those attached to some of the attendees. Of course the corporate whores...errrr, vendors were in place, ready to parlay the convention's fre-nerd-ic energy into millions of dollars by convincing the big-brained and under-sexed in the crowd (i.e., virtually all of them...present company excluded, of course) that their product or service was the only thing standing between them and professional success, industry fame, and clear skin. "With KramTech 2012," they seemed to scream, "you will be THE ROCK STAR of your company's IT department!" As car shows and tattoo parlors learned long ago, Tech companies seem to believe that the best way to attract the attention of this crowd is through the hint of the promise of sex. They recruit and deploy an army of "sales reps" whose primary qualifications appear to be long hair, short skirts, high heels, and a vagina. Unlike their distant cousins in the car and body art industries, however, this sub-species of booth paint (semi-gloss decoration that adds nothing to the substance of the product) seems torn between committing to being all-out sex objects and recognition that they are in the presence of intelligent, discerning people. People who are smart enough to know exactly what these vendors are doing. Also unlike their distant car show and tattoo shop cousins, these young women (what…are there no gay tech professionals who could use some eye candy?) seem to realize that while IT remains a male-dominated field, there are ever-increasing numbers of intelligent, capable, strong professional women – women who’ve battled to make it in this field through hard work and work performance rather than a hard body and performing after work. This is not to say that all of the young female sales reps are there only because of their physical attributes. Many are competent, intelligent, and driven -- not to mention attractive. They're working hard on the front lines of delivering the next generation of technology. The distinction is pretty clear, however, between these young professionals and the booth paint. The former enthusiastically deliver credible information about the products they’re hawking. The latter are positioned in the aisles, uncomfortably avoiding eye contact as they struggle to operate the badge readers. Surprisingly, not all of the women in attendance seemed to object to the objectification of their younger sisters. One IT professional woman who came of age in the industry (mostly in IT marketing) said, “I have no problem with it. I was a ‘booth babe’ for years and it doesn’t bother me at all.” Others, however, weren’t quite so gracious. One woman I spoke with, an IT manager from Cheyenne, Wyoming, said it was demeaning and frankly, as more and more women grow into IT management positions, not a great marketing idea. “Using these young women is, to me, no different than vendors giving out t-shirts to attract attention. It’s sad because it’s still hard for a woman to be respected in the IT field and this just perpetuates the outdated notion that IT is a male-dominated field.” She went on to say that decisions by vendors to employ these young women in this “inappropriate way” could impact her purchasing decisions. “I might be swayed toward a vendor who has women on staff who are intelligent and dynamic rather than the vendors who use the ‘decoration’ girls.” So in many ways, the IT industry is no different than most other industries as it struggles to maximize performance by finding and developing talent – all of the talent, not just the 50% with a penis. Women in IT, like their brethren, struggle to find their niche in the field, to grow professionally, and reach for the brass ring, struggling to overcome obstacles as they climb the mountain of professional success in a never-ending cycle of economic uncertainty. But as (generally) well-educated and highly-trained professionals, they are probably better positioned than those in many other industries. Beside, they’ve got one other advantage over their non-IT counterparts as they attempt their ascent to the summit: They’ve already got the backpacks.

• Talend Enterprise Data Integration overperforms on Oracle SPARC T4

  - by Amir Javanshir

  The SPARC T microprocessor, released in 2005 by Sun Microsystems, and now continued at Oracle, has a good track record in parallel execution and multi-threaded performance. However it was less suited for pure single-threaded workloads. The new SPARC T4 processor is now filling that gap by offering a 5x better single-thread performance over previous generations. Following our long-term relationship with Talend, a fast growing ISV positioned by Gartner in the “Visionaries” quadrant of the “Magic Quadrant for Data Integration Tools”, we decided to test some of their integration components with the T4 chip, more precisely on a T4-1 system, in order to verify first hand if this new processor stands up to its promises. Several tests were performed, mainly focused on: Single-thread performance of the new SPARC T4 processor compared to an older SPARC T2+ processor Overall throughput of the SPARC T4-1 server using multiple threads The tests consisted in reading large amounts of data --ten's of gigabytes--, processing and writing them back to a file or an Oracle 11gR2 database table. They are CPU, memory and IO bound tests. Given the main focus of this project --CPU performance--, bottlenecks were removed as much as possible on the memory and IO sub-systems. When possible, the data to process was put into the ZFS filesystem cache, for instance. Also, two external storage devices were directly attached to the servers under test, each one divided in two ZFS pools for read and write operations. Multi-thread: Testing throughput on the Oracle T4-1 The tests were performed with different number of simultaneous threads (1, 2, 4, 8, 12, 16, 32, 48 and 64) and using different storage devices: Flash, Fibre Channel storage, two stripped internal disks and one single internal disk. All storage devices used ZFS as filesystem and volume management. Each thread read a dedicated 1GB-large file containing 12.5M lines with the following structure: customerID;FirstName;LastName;StreetAddress;City;State;Zip;Cust_Status;Since_DT;Status_DT 1;Ronald;Reagan;South Highway;Santa Fe;Montana;98756;A;04-06-2006;09-08-2008 2;Theodore;Roosevelt;Timberlane Drive;Columbus;Louisiana;75677;A;10-05-2009;27-05-2008 3;Andrew;Madison;S Rustle St;Santa Fe;Arkansas;75677;A;29-04-2005;09-02-2008 4;Dwight;Adams;South Roosevelt Drive;Baton Rouge;Vermont;75677;A;15-02-2004;26-01-2007 […] The following graphs present the results of our tests: Unsurprisingly up to 16 threads, all files fit in the ZFS cache a.k.a L2ARC : once the cache is hot there is no performance difference depending on the underlying storage. From 16 threads upwards however, it is clear that IO becomes a bottleneck, having a good IO subsystem is thus key. Single-disk performance collapses whereas the Sun F5100 and ST6180 arrays allow the T4-1 to scale quite seamlessly. From 32 to 64 threads, the performance is almost constant with just a slow decline. For the database load tests, only the best IO configuration --using external storage devices-- were used, hosting the Oracle table spaces and redo log files. Using the Sun Storage F5100 array allows the T4-1 server to scale up to 48 parallel JVM processes before saturating the CPU. The final result is a staggering 646K lines per second insertion in an Oracle table using 48 parallel threads. Single-thread: Testing the single thread performance Seven different tests were performed on both servers. Given the fact that only one thread, thus one file was read, no IO bottleneck was involved, all data being served from the ZFS cache. Read File ? Filter ? Write File: Read file, filter data, write the filtered data in a new file. The filter is set on the “Status” column: only lines with status set to “A” are selected. This limits each output file to about 500 MB. Read File ? Load Database Table: Read file, insert into a single Oracle table. Average: Read file, compute the average of a numeric column, write the result in a new file. Division & Square Root: Read file, perform a division and square root on a numeric column, write the result data in a new file. Oracle DB Dump: Dump the content of an Oracle table (12.5M rows) into a CSV file. Transform: Read file, transform, write the result data in a new file. The transformations applied are: set the address column to upper case and add an extra column at the end, which is the concatenation of two columns. Sort: Read file, sort a numeric and alpha numeric column, write the result data in a new file. The following table and graph present the final results of the tests: Throughput unit is thousand lines per second processed (K lines/second). Improvement is the % of improvement between the T5140 and T4-1. Test T4-1 (Time s.) T5140 (Time s.) Improvement T4-1 (Throughput) T5140 (Throughput) Read/Filter/Write 125 806 645% 100 16 Read/Load Database 195 1111 570% 64 11 Average 96 557 580% 130 22 Division & Square Root 161 1054 655% 78 12 Oracle DB Dump 164 945 576% 76 13 Transform 159 1124 707% 79 11 Sort 251 1336 532% 50 9 The improvement of single-thread performance is quite dramatic: depending on the tests, the T4 is between 5.4 to 7 times faster than the T2+. It seems clear that the SPARC T4 processor has gone a long way filling the gap in single-thread performance, without sacrifying the multi-threaded capability as it still shows a very impressive scaling on heavy-duty multi-threaded jobs. Finally, as always at Oracle ISV Engineering, we are happy to help our ISV partners test their own applications on our platforms, so don't hesitate to contact us and let's see what the SPARC T4-based systems can do for your application! "As describe in this benchmark, Talend Enterprise Data Integration has overperformed on T4. I was generally happy to see that the T4 gave scaling opportunities for many scenarios like complex aggregations. Row by row insertion in Oracle DB is faster with more than 650,000 rows per seconds without using any bulk Oracle capabilities !" Cedric Carbone, Talend CTO.

• Dynamic Bursting ... no really!

  - by Tim Dexter

  If any of you have seen me or my colleagues present BI Publisher to you then we have hopefully mentioned 'bursting.' You may have even seen a demo where we talk about being able to take a batch of data, say invoices. Then split them by some criteria, say customer id; format them with a template; generate the output and then deliver the documents to the recipients with a click. We and especially I, always say this can be completely dynamic! By this I mean, that you could store customer preferences in a database. What layout would each customer like; what output format they would like and how they would like the document delivered. We (I) talk a good talk, but typically don't do the walk in a demo. We hard code everything in the bursting query or bursting control file to get the concept across. But no more peeps! I have finally put together a dynamic bursting demo! Its been minutes in the making but its been tough to find those minutes! Read on ... It's nothing amazing in terms of making the burst dynamic. I created a CUSTOMER_PREFS table with some simple UI in an APEX application so that I can maintain their requirements. In EBS you have descriptive flexfields that could do the same thing or probably even 'contact' fields to store most of the info. Here's my table structure: Name                           Type ------------------------------ -------- CUSTOMER_ID                    NUMBER(6) TEMPLATE_TYPE                  VARCHAR2(20) TEMPLATE_NAME                  VARCHAR2(120) OUTPUT_FORMAT                  VARCHAR2(20) DELIVERY_CHANNEL               VARCHAR2(50) EMAIL                          VARCHAR2(255) FAX                            VARCHAR2(20) ATTACH                         VARCHAR2(20) FILE_LOC                       VARCHAR2(255) Simple enough right? Just need CUSTOMER_ID as the key for the bursting engine to join it to the customer data at burst time. I have not covered the full delivery options, just email, fax and file location. Remember, its a demo people :0) However the principal is exactly the same for each delivery type. They each have a set of attributes that need to be provided and you will need to handle that in your bursting query. On a side note, in EBS, you use a bursting control file, you can apply the same principals that I'm laying out here you just need to get the customer bursting info into the XML data stream so that you can refer to it in the control file using XPATH expressions. Next, we need to look up what attributes or parameters are required for each delivery method. that can be found in the documentation here.  Now we know the combinations of parameters and delivery methods we can construct the query using a series a decode statements: select distinct cp.customer_id "KEY", cp.template_name TEMPLATE, cp.template_type TEMPLATE_FORMAT, 'en-US' LOCALE, cp.output_format OUTPUT_FORMAT, 'false' SAVE_FORMAT, cp.delivery_channel DEL_CHANNEL, decode(cp.delivery_channel,'FILE', cp.file_loc , 'EMAIL', cp.email , 'FAX', cp.fax) PARAMETER1, decode(cp.delivery_channel,'FILE', c.cust_last_name||'_orders.pdf' ,'EMAIL','[email protected]' ,'FAX', 'faxserver.com') PARAMETER2, decode(cp.delivery_channel,'FILE',NULL ,'EMAIL','[email protected]' ,'FAX', null) PARAMETER3, decode(cp.delivery_channel,'FILE',NULL ,'EMAIL','Your current orders' ,'FAX',NULL) PARAMETER4, decode(cp.delivery_channel,'FILE',NULL ,'EMAIL','Please find attached a copy of your current orders with BI Publisher, Inc' ,'FAX',NULL) PARAMETER5, decode(cp.delivery_channel,'FILE',NULL ,'EMAIL','false' ,'FAX',NULL) PARAMETER6, decode(cp.delivery_channel,'FILE',NULL ,'EMAIL','[email protected]' ,'FAX',NULL) PARAMETER7 from cust_prefs cp, customers c, orders_view ov where cp.customer_id = c.customer_id and cp.customer_id = ov.customer_id order by cp.customer_id Pretty straightforward, just need to test, test, test, the query and ensure it's bringing back the correct data based on each customers preferences. Notice the NULL values for parameters that are not relevant for a given delivery channel. You should end up with bursting control data that the bursting engine can use:  Now, your users can run the burst and documents will be formatted, generated and delivered based on the customer prefs. If you're interested in the example, I have used the sample OE schema data for the base report. The report files and CUST_PREFS table are zipped up here. The zip contains the data model (.xdmz), the report and templates (.xdoz) and the sql scripts to create and load data to the CUST_PREFS table.  Once you load the report into the catalog, you'll need to create the OE data connection and point the data model at it. You'll probably need to re-point the report to the data model too. Happy Bursting!

• Sea Monkey Sales & Marketing, and what does that have to do with ERP?

  - by user709270

  Tier One Defined By Lyle Ekdahl, Oracle JD Edwards Group Vice President and General Manager  I recently became aware of the latest Sea Monkey Sales & Marketing tactic. Wait now, what is Sea Monkey Sales & Marketing and what does that have to do with ERP? Well if you grew up in USA during the 50’s, 60’s and maybe a bit in the early 70’s there was a unifying media of culture known as the comic book. I was a big Iron Man fan. I always liked the troubled hero aspect of Tony Start and hey he was a technologist. This is going somewhere, just hold on. Of course comic books like most media contained advertisements. Ninety pound weakling transformed by Charles Atlas in just 15 minutes per day. Baby Ruth, Juicy Fruit Gum and all assortments of Hostess goodies were on display. The best ad was for the “Amazing Live Sea-Monkeys – The real live fun-pets you grow yourself!” These ads set the standard for exaggeration and half-truth; “…they love attention…so eager to please, they can even be trained…” The cartoon picture on the ad is of a family of royal looking sea creatures – daddy, mommy, son and little sis – sea monkey? There was a disclaimer at the bottom in fine print, “Caricatures shown not intended to depict Artemia.” Ok what ten years old knows what the heck artemia is? Well you grow up fast once you’ve been separated from your buck twenty five plus postage just to discover that it is brine shrimp. Really dumb brine shrimp that don’t take commands or do tricks. Unfortunately the technology industry is full of sea monkey sales and marketing. Yes believe it or not in some cases there is subterfuge and obfuscation used to secure contracts. Hey I get it; the picture on the box might not be the actual size. Make up what you want about your product, but here is what I don’t like, could you leave out the obvious falsity when it comes to my product, especially the negative stuff. So here is the latest one – “Oracle’s JD Edwards is NOT tier one”. Really? Definition please! Well a whole host of googleable and reputable sources confirm that a tier one vendor is large, well known, and enjoys national and international recognition. Let me see large, so thousands of customers? Oh and part of the world’s largest business software and hardware corporation? Check and check JD Edwards has that and that. Well known, enjoying national and international recognition? Oracle’s JD Edwards EnterpriseOne is available in 21 languages and is directly localized in 33 countries that support some of the world’s largest multinationals and many midsized domestic market companies. Something on the order of half the JD Edwards customer base is outside North America. My passport is on its third insert after 2 years and not from vacations. So if you don’t mind I am going to mark national and international recognition in the got it column. So what else is there? Well let me offer a few criteria. Longevity – The JD Edwards products benefit from 35+ years of intellectual property development; through booms, busts, mergers and acquisitions, we are still here Vision & innovation – JD Edwards is the first full suite ERP to run on the iPad as just one example Proven track record of execution – Since becoming part of Oracle, JD Edwards has released to the market over 20 deliverables including major release, point releases, new apps modules, tool releases, integrations…. Solid, focused functionality with a flexible, interoperable, extensible underlying architecture – JD Edwards offers solid core ERP with specialty modules for verticals all delivered on a well defined independent tools layer that helps enable you to scale your business without an ERP reimplementation A continuation plan – Oracle’s JD Edwards offers our customers a 6 year roadmap as well as interoperability with Oracle’s next generation of applications Oh I almost forgot that the expert sources agree on one additional thing, tier one may be a preferred vendor that offers product and services to you with appealing value. You should check out the TCO studies of JD Edwards. I think you will see what the thousands of customers that rely on these products to run their businesses enjoy – that is the tier one solution with the lowest TCO. Oh and if you get an offer to buy an ERP for no license charge, remember the picture on the box might not be the actual size.

• The Unspoken - The Why of GC Ergonomics

  - by jonthecollector

  Do you use GC ergonomics, -XX:+UseAdaptiveSizePolicy, with the UseParallelGC collector? The jist of GC ergonomics for that collector is that it tries to grow or shrink the heap to meet a specified goal. The goals that you can choose are maximum pause time and/or throughput. Don't get too excited there. I'm speaking about UseParallelGC (the throughput collector) so there are definite limits to what pause goals can be achieved. When you say out loud "I don't care about pause times, give me the best throughput I can get" and then say to yourself "Well, maybe 10 seconds really is too long", then think about a pause time goal. By default there is no pause time goal and the throughput goal is high (98% of the time doing application work and 2% of the time doing GC work). You can get more details on this in my very first blog. GC ergonomics The UseG1GC has its own version of GC ergonomics, but I'll be talking only about the UseParallelGC version. If you use this option and wanted to know what it (GC ergonomics) was thinking, try -XX:AdaptiveSizePolicyOutputInterval=1 This will print out information every i-th GC (above i is 1) about what the GC ergonomics to trying to do. For example, UseAdaptiveSizePolicy actions to meet *** throughput goal *** GC overhead (%) Young generation: 16.10 (attempted to grow) Tenured generation: 4.67 (attempted to grow) Tenuring threshold: (attempted to decrease to balance GC costs) = 1 GC ergonomics tries to meet (in order) Pause time goal Throughput goal Minimum footprint The first line says that it's trying to meet the throughput goal. UseAdaptiveSizePolicy actions to meet *** throughput goal *** This run has the default pause time goal (i.e., no pause time goal) so it is trying to reach a 98% throughput. The lines Young generation: 16.10 (attempted to grow) Tenured generation: 4.67 (attempted to grow) say that we're currently spending about 16% of the time doing young GC's and about 5% of the time doing full GC's. These percentages are a decaying, weighted average (earlier contributions to the average are given less weight). The source code is available as part of the OpenJDK so you can take a look at it if you want the exact definition. GC ergonomics is trying to increase the throughput by growing the heap (so says the "attempted to grow"). The last line Tenuring threshold: (attempted to decrease to balance GC costs) = 1 says that the ergonomics is trying to balance the GC times between young GC's and full GC's by decreasing the tenuring threshold. During a young collection the younger objects are copied to the survivor spaces while the older objects are copied to the tenured generation. Younger and older are defined by the tenuring threshold. If the tenuring threshold hold is 4, an object that has survived fewer than 4 young collections (and has remained in the young generation by being copied to the part of the young generation called a survivor space) it is younger and copied again to a survivor space. If it has survived 4 or more young collections, it is older and gets copied to the tenured generation. A lower tenuring threshold moves objects more eagerly to the tenured generation and, conversely a higher tenuring threshold keeps copying objects between survivor spaces longer. The tenuring threshold varies dynamically with the UseParallelGC collector. That is different than our other collectors which have a static tenuring threshold. GC ergonomics tries to balance the amount of work done by the young GC's and the full GC's by varying the tenuring threshold. Want more work done in the young GC's? Keep objects longer in the survivor spaces by increasing the tenuring threshold. This is an example of the output when GC ergonomics is trying to achieve a pause time goal UseAdaptiveSizePolicy actions to meet *** pause time goal *** GC overhead (%) Young generation: 20.74 (no change) Tenured generation: 31.70 (attempted to shrink) The pause goal was set at 50 millisecs and the last GC was 0.415: [Full GC (Ergonomics) [PSYoungGen: 2048K-0K(26624K)] [ParOldGen: 26095K-9711K(28992K)] 28143K-9711K(55616K), [Metaspace: 1719K-1719K(2473K/6528K)], 0.0758940 secs] [Times: user=0.28 sys=0.00, real=0.08 secs] The full collection took about 76 millisecs so GC ergonomics wants to shrink the tenured generation to reduce that pause time. The previous young GC was 0.346: [GC (Allocation Failure) [PSYoungGen: 26624K-2048K(26624K)] 40547K-22223K(56768K), 0.0136501 secs] [Times: user=0.06 sys=0.00, real=0.02 secs] so the pause time there was about 14 millisecs so no changes are needed. If trying to meet a pause time goal, the generations are typically shrunk. With a pause time goal in play, watch the GC overhead numbers and you will usually see the cost of setting a pause time goal (i.e., throughput goes down). If the pause goal is too low, you won't achieve your pause time goal and you will spend all your time doing GC. GC ergonomics is meant to be simple because it is meant to be used by anyone. It was not meant to be mysterious and so this output was added. If you don't like what GC ergonomics is doing, you can turn it off with -XX:-UseAdaptiveSizePolicy, but be pre-warned that you have to manage the size of the generations explicitly. If UseAdaptiveSizePolicy is turned off, the heap does not grow. The size of the heap (and the generations) at the start of execution is always the size of the heap. I don't like that and tried to fix it once (with some help from an OpenJDK contributor) but it unfortunately never made it out the door. I still have hope though. Just a side note. With the default throughput goal of 98% the heap often grows to it's maximum value and stays there. Definitely reduce the throughput goal if footprint is important. Start with -XX:GCTimeRatio=4 for a more modest throughput goal (%20 of the time spent in GC). A higher value means a smaller amount of time in GC (as the throughput goal).

• Record Screen Activity with CamStudio

  - by Asian Angel

  Sometimes a visual demonstration works much better than a list of instructions. If you need to make a demo video for family and/or friends then you might want to have a look at CamStudio. Using CamStudio To get properly set up you will need to install two different files (the main program followed by the codec). Once that is done you are ready to get started. When you start the program you will see a surprisingly small window. Notice the highlighted Record to text…it serves as a visual indicator for the video type selected for recording. Before you start creating a video it would be a good idea to look through some of the settings. The first one to look at is the region or area that you want to record. Next you will want to look through the video options since these will affect the quality and final size of your video files. The default setting for quality is 70…adjust that to the level that best suits your needs. Note: For our example we maxed out the various video settings for best quality. On our system Microsoft Video 1 was listed as the default compressor but as you can see there were other options available. You can configure the settings for the compressor you want to use if desired. Keep in mind that each compressor will have unique settings of their own, so if you change it, be certain to go back and check. We decided to use the CamStudio Lossless Codec for our example (it gave the best results while trying the software). Going back to the main window you can toggle back and forth between .avi and .swf output using the last button. Once you are satisfied with the settings click on the red record button to start. If you need to pause while recording or stop recording click on the system tray icon and select the appropriate command. When you are finished recording, you will be presented with the save file window. Browse for the desired save location and name your new file. Once you have saved the file the movie player window will automatically open so that you view your new video. Our sample video shown here is at 50% of original size so may look slightly “gritty”. The detail was much better at 100%. If you decide to record and save as .swf the process will be identical to recording in .avi format until the movie player window opens. At that time the conversion process from .avi to .swf will begin. When complete you will have a new flash video and html file that goes with it. Depending on which browser you have set as default, you may run into a small problem when the preview for your new .swf file tries to open. There is a small bug in the generated html file. You can use this work-around or… Just open the .swf file directly in your favorite browser. Conclusion CamStudio may not produce the highest quality videos, but it’s free and does a very nice job nonetheless. If you are working on a tight budget or only need to make an occasional video then CamStudio is a very sensible choice.

• TFS 2010 SDK: Integrating Twitter with TFS Programmatically

  - by Tarun Arora

  Technorati Tags: Team Foundation Server 2010,TFS API,Integrate Twitter TFS,TFS Programming,ALM,TwitterSharp   Friends at ‘Twitter Sharp’ have created a wonderful .net API for twitter. With this blog post i will try to show you a basic TFS – Twitter integration scenario where i will retrieve the Team Project details programmatically and then publish these details on my twitter page. In future blogs i will be demonstrating how to create a windows service to capture the events raised by TFS and then publishing them in your social eco-system. Download Working Demo: Integrate Twitter - Tfs Programmatically   1. Setting up Twitter API Download Tweet Sharp from => https://github.com/danielcrenna/tweetsharp  Before you can start playing around with this, you will need to register an application on twitter. This is because Twitter uses the OAuth authentication protocol and will not issue an Access token unless your application is registered with them. Go to https://dev.twitter.com/ and register your application   Once you have registered your application, you will need ‘Customer Key’, ‘Customer Secret’, ‘Access Token’, ‘Access Token Secret’ 2. Connecting to Twitter using the Tweet Sharp API Create a new C# windows forms project and add reference to ‘Hammock.ClientProfile’, ‘Newtonsoft.Json’, ‘TweetSharp’ Add the following keys to the App.config (Note – The values for the keys below are in correct and if you try and connect using them then you will get an authorization failure error). Add a new class ‘TwitterProxy’ and use the following code to connect to the TwitterService (Read more about OAuthentication - http://dev.twitter.com/pages/auth) using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Configuration;using TweetSharp; namespace WindowsFormsApplication2{ public class TwitterProxy { private static string _hero; private static string _consumerKey; private static string _consumerSecret; private static string _accessToken; private static string _accessTokenSecret;  public static TwitterService ConnectToTwitter() { _consumerKey = ConfigurationManager.AppSettings["ConsumerKey"]; _consumerSecret = ConfigurationManager.AppSettings["ConsumerSecret"]; _accessToken = ConfigurationManager.AppSettings["AccessToken"]; _accessTokenSecret = ConfigurationManager.AppSettings["AccessTokenSecret"];  return new TwitterService(_consumerKey, _consumerSecret, _accessToken, _accessTokenSecret); } }} Time to Tweet! _twitterService = Proxy.TwitterProxy.ConnectToTwitter(); _twitterService.SendTweet("Hello World"); SendTweet will return the TweetStatus, If you do not get a 200 OK status that means you have failed authentication, please revisit the Access tokens. --RESPONSE: https://api.twitter.com/1/statuses/update.json HTTP/1.1 200 OK X-Transaction: 1308476106-69292-41752 X-Frame-Options: SAMEORIGIN X-Runtime: 0.03040 X-Transaction-Mask: a6183ffa5f44ef11425211f25 Pragma: no-cache X-Access-Level: read-write X-Revision: DEV X-MID: bd8aa0abeccb6efba38bc0a391a73fab98e983ea Cache-Control: no-cache, no-store, must-revalidate, pre-check=0, post-check=0 Content-Type: application/json; charset=utf-8 Date: Sun, 19 Jun 2011 09:35:06 GMT Expires: Tue, 31 Mar 1981 05:00:00 GMT Last-Modified: Sun, 19 Jun 2011 09:35:06 GMT Server: hi Vary: Accept-Encoding Content-Encoding: Keep-Alive: timeout=15, max=100 Connection: Keep-Alive Transfer-Encoding: chunked   3.

• .NET 4: &ldquo;Slim&rdquo;-style performance boost!

  - by Vitus

  RTM version of .NET 4 and Visual Studio 2010 is available, and now we can do some test with it. Parallel Extensions is one of the most valuable part of .NET 4.0. It’s a set of good tools for easily consuming multicore hardware power. And it also contains some “upgraded” sync primitives – Slim-version. For example, it include updated variant of widely known ManualResetEvent. For people, who don’t know about it: you can sync concurrency execution of some pieces of code with this sync primitive. Instance of ManualResetEvent can be in 2 states: signaled and non-signaled. Transition between it possible by Set() and Reset() methods call. Some shortly explanation: Thread 1 Thread 2 Time mre.Reset(); mre.WaitOne(); //code execution 0 //wating //code execution 1 //wating //code execution 2 //wating //code execution 3 //wating mre.Set(); 4 //code execution //… 5 Upgraded version of this primitive is ManualResetEventSlim. The idea in decreasing performance cost in case, when only 1 thread use it. Main concept in the “hybrid sync schema”, which can be done as following:   internal sealed class SimpleHybridLock : IDisposable { private Int32 m_waiters = 0; private AutoResetEvent m_waiterLock = new AutoResetEvent(false);   public void Enter() { if (Interlocked.Increment(ref m_waiters) == 1) return; m_waiterLock.WaitOne(); }   public void Leave() { if (Interlocked.Decrement(ref m_waiters) == 0) return; m_waiterLock.Set(); }   public void Dispose() { m_waiterLock.Dispose(); } } It’s a sample from Jeffry Richter’s book “CLR via C#”, 3rd edition. Primitive SimpleHybridLock have two public methods: Enter() and Leave(). You can put your concurrency-critical code between calls of these methods, and it would executed in only one thread at the moment. Code is really simple: first thread, called Enter(), increase counter. Second thread also increase counter, and suspend while m_waiterLock is not signaled. So, if we don’t have concurrent access to our lock, “heavy” methods WaitOne() and Set() will not called. It’s can give some performance bonus. ManualResetEvent use the similar idea. Of course, it have more “smart” technics inside, like a checking of recursive calls, and so on. I want to know a real difference between classic ManualResetEvent realization, and new –Slim. I wrote a simple “benchmark”: class Program { static void Main(string[] args) { ManualResetEventSlim mres = new ManualResetEventSlim(false); ManualResetEventSlim mres2 = new ManualResetEventSlim(false);   ManualResetEvent mre = new ManualResetEvent(false);   long total = 0; int COUNT = 50;   for (int i = 0; i < COUNT; i++) { mres2.Reset(); Stopwatch sw = Stopwatch.StartNew();   ThreadPool.QueueUserWorkItem((obj) => { //Method(mres, true); Method2(mre, true); mres2.Set(); }); //Method(mres, false); Method2(mre, false);   mres2.Wait(); sw.Stop();   Console.WriteLine("Pass {0}: {1} ms", i, sw.ElapsedMilliseconds); total += sw.ElapsedMilliseconds; }   Console.WriteLine(); Console.WriteLine("==============================="); Console.WriteLine("Done in average=" + total / (double)COUNT); Console.ReadLine(); }   private static void Method(ManualResetEventSlim mre, bool value) { for (int i = 0; i < 9000000; i++) { if (value) { mre.Set(); } else { mre.Reset(); } } }   private static void Method2(ManualResetEvent mre, bool value) { for (int i = 0; i < 9000000; i++) { if (value) { mre.Set(); } else { mre.Reset(); } } } } I use 2 concurrent thread (the main thread and one from thread pool) for setting and resetting ManualResetEvents, and try to run test COUNT times, and calculate average execution time. Here is the results (I get it on my dual core notebook with T7250 CPU and Windows 7 x64): ManualResetEvent ManualResetEventSlim Difference is obvious and serious – in 10 times! So, I think preferable way is using ManualResetEventSlim, because not always on calling Set() and Reset() will be called “heavy” methods for working with Windows kernel-mode objects. It’s a small and nice improvement! ;)

• Great event : Microsoft Visual Studio 2010 Launch @ Microsoft TechEd Blore

  - by sathya

  Great event : Microsoft Visual Studio 2010 Launch @ Microsoft TechEd Blore   I was really excited on attending the day 1 of Microsoft TechEd 2010 in Bangalore. This is the first Teched that am attending. The event was really fun filled with lot of knowledge sharing sessions and lots of goodies and gifts by the partners Initially the Event Started by Murthy's Session. He explained about the Developers relating to the 5 elements of nature (Pancha Boothaas) 1. Fire - Passion 2. Wave (Water) - Catch the right wave which we need to apply. 3. Earth - Connections and lots of opportunities around the world 4. Air -  Its whatever we breathe. Developers.. Without them nothing is possible. they are like the air 5. Sky - Cloud based applications   Next the Keynote and the announcement of Visual Studio by SomaSegar. List of things that he delivered his speech on : 1. Announcement of Visual Studio 2010 2. Announcement of .NET 4.0 3. Announcement of Silverlight later this week 4. What is the current Trend? Microsoft has done a research with many developers across the globe and have got the following feedback from the users. Get Lost (interrupted) - When we do some work and somebody is calling or interrepting by someother way we lose track of what we were doing and we need to do from the start Falling Behind- Technology gets updated  phenomenally over a period of time and developers always have a scenario like they are not in the state of the art technology and they always have a doubt whether they are staying updated. Lack of Collobaration - When a Manager asks a person what the team members have done and some might be done and some might not be and finally all are into a state like we dont know where we are. So they have addressed these 3 points in the VS 2010 by the following features : Get Lost - Some cool features which could overcome this. We have some Graphical interface. which could show what we have done and where we are. Some Zoom features in the code level. Falling Behind - Everything is based on .NET language base. 2010 has been built in such a way that if developers know the native language that's enough for building good applications. Lack of Collobaration - Some Dashboard Features which would show where exactly the project is. And a graphical user interface is shown on clicking which it directly drills down even to the code level. 5. An overview on all new features in VS 2010. 6. Some good demos of new features in VS 2010 by Polita and one more girl. Some of the new features included : 1. Team Explorer 2. Zoom in Code 3. Ribbon Development 4. Development in Single Platform for Windows Phone, XBox, Zune, Azure, Web Based and Windows based applications 5. Sequence Diagram Generation directly from code 6. Dashboards to show project status 7. Javascript and JQuery intellisense 8. Native support for JQuery 9. Packaging feature while deploying. 10. Generation of different versions of web.config like Web.Config.Production, Web.Config.Staging, etc. 11. IntelliTrace - Eliminating the "Not Reproducible" statement. 12. Automated User Interface Testing. At last in the closing of the day we had a great event called Demo Extravaganza, where lot of cool projects that were launched by Microsoft and also the projects that are under research were also shown. I got a lot of info about Bing today. BING really rocks!!! It has the following : 1. Visual Search 2. Product based search. For each product different menu filters were provided to make an advanced search 3. BING Maps was awesome!! It zoomed in to the street level and we can assume that we are the persons who are walking or running on the road and we can see the real objects like buildings moving by our side. 4. PhotoSynth was used in BING to show up all the images taken around the globe in a 3D format. 5. Formula - If we give some formula it automatically gives the value for the variable or derivation of expression Also some info about some kool touch apps which does an authentication and computation of Teched Attendee's Points that they have scored and the sessions attended. One guy won an XBOX in lucky draw as a gift. There were lot of Partner Stalls like Accenture,Intel,Citrix,MicroFocus,Telerik,infragistics,Sapient etc. Some Offers were provided for us like 50% off on Certifications, 1 free Elearning Course, etc. Stay tuned!! Wil update you on other events too..

• Fun With the Chrome JavaScript Console and the Pluralsight Website

  - by Steve Michelotti

  Originally posted on: http://geekswithblogs.net/michelotti/archive/2013/07/24/fun-with-the-chrome-javascript-console-and-the-pluralsight-website.aspxI’m currently working on my third course for Pluralsight. Everyone already knows that Scott Allen is a “dominating force” for Pluralsight but I was curious how many courses other authors have published as well. The Pluralsight Authors page - http://pluralsight.com/training/Authors – shows all 146 authors and you can click on any author’s page to see how many (and which) courses they have authored. The problem is: I don’t want to have to click into 146 pages to get a count for each author. With this in mind, I figured I could write a little JavaScript using the Chrome JavaScript console to do some “detective work.” My first step was to figure out how the HTML was structured on this page so I could do some screen-scraping. Right-click the first author - “Inspect Element”. I can see there is a primary <div> with a class of “main” which contains all the authors. Each author is in an <h3> with an <a> tag containing their name and link to their page:     This web page already has jQuery loaded so I can use $ directly from the console. This allows me to just use jQuery to inspect items on the current page. Notice this is a multi-line command. In order to use multiple lines in the console you have to press SHIFT-ENTER to go to the next line:     Now I can see I’m extracting data just fine. At this point I want to follow each URL. Then I want to screen-scrape this next page to see how many courses each author has done. Let’s take a look at the author detail page:       I can see we have a table (with a css class of “course”) that contains rows for each course authored. This means I can get the number of courses pretty easily like this:     Now I can put this all together. Back on the authors page, I want to follow each URL, extract the returned HTML, and grab the count. In the code below, I simply use the jQuery $.get() method to get the author detail page and the “data” variable that is in the callback contains the HTML. A nice feature of jQuery is that I can simply put this HTML string inside of $() and I can use jQuery selectors directly on it in conjunction with the find() method:     Now I’m getting somewhere. I have every Pluralsight author and how many courses each one has authored. But that’s not quite what I’m after – what I want to see are the authors that have the MOST courses in the library. What I’d like to do is to put all of the data in an array and then sort that array descending by number of courses. I can add an item to the array after each author detail page is returned but the catch here is that I can’t perform the sort operation until ALL of the author detail pages have executed. The jQuery $.get() method is naturally an async method so I essentially have 146 async calls and I don’t want to perform my sort action until ALL have completed (side note: don’t run this script too many times or the Pluralsight servers might think your an evil hacker attempting a DoS attack and deny you). My C# brain wants to use a WaitHandle WaitAll() method here but this is JavaScript. I was able to do this by using the jQuery Deferred() object. I create a new deferred object for each request and push it onto a deferred array. After each request is complete, I signal completion by calling the resolve() method. Finally, I use a $.when.apply() method to execute my descending sort operation once all requests are complete. Here is my complete console command: 1: var authorList = [], 2: defList = []; 3: $(".main h3 a").each(function() { 4: var def = $.Deferred(); 5: defList.push(def); 6: var authorName = $(this).text(); 7: var authorUrl = $(this).attr('href'); 8: $.get(authorUrl, function(data) { 9: var courseCount = $(data).find("table.course tbody tr").length; 10: authorList.push({ name: authorName, numberOfCourses: courseCount }); 11: def.resolve(); 12: }); 13: }); 14: $.when.apply($, defList).then(function() { 15: console.log("*Everything* is complete"); 16: var sortedList = authorList.sort(function(obj1, obj2) { 17: return obj2.numberOfCourses - obj1.numberOfCourses; 18: }); 19: for (var i = 0; i < sortedList.length; i++) { 20: console.log(authorList[i]); 21: } 22: });   And here are the results:     WOW! John Sonmez has 44 courses!! And Matt Milner has 29! I guess Scott Allen isn’t the only “dominating force”. I would have assumed Scott Allen was #1 but he comes in as #3 in total course count (of course Scott has 11 courses in the Top 50, and 14 in the Top 100 which is incredible!). Given that I’m in the middle of producing only my third course, I better get to work!

• JDK bug migration: components and subcomponents

  - by darcy

  One subtask of the JDK migration from the legacy bug tracking system to JIRA was reclassifying bugs from a three-level taxonomy in the legacy system, (product, category, subcategory), to a fundamentally two-level scheme in our customized JIRA instance, (component, subcomponent). In the JDK JIRA system, there is technically a third project-level classification, but by design a large majority of JDK-related bugs were migrated into a single "JDK" project. In the end, over 450 legacy subcategories were simplified into about 120 subcomponents in JIRA. The 120 subcomponents are distributed among 17 components. A rule of thumb used was that a subcategory had to have at least 50 bugs in it for it to be retained. Below is a listing the component / subcomponent classification of the JDK JIRA project along with some notes and guidance on which OpenJDK email addresses cover different areas. Eventually, a separate incidents project to host new issues filed at bugs.sun.com will use a slightly simplified version of this scheme. The preponderance of bugs and subcomponents for the JDK are in library-related areas, with components named foo-libs and subcomponents primarily named after packages. While there was an overall condensation of subcomponents in the migration, in some cases long-standing informal divisions in core libraries based on naming conventions in the description were promoted to formal subcomponents. For example, hundreds of bugs in the java.util subcomponent whose descriptions started with "(coll)" were moved into java.util:collections. Likewise, java.lang bugs starting with "(reflect)" and "(proxy)" were moved into java.lang:reflect. client-libs (Predominantly discussed on 2d-dev and awt-dev and swing-dev.) 2d demo java.awt java.awt:i18n java.beans (See beans-dev.) javax.accessibility javax.imageio javax.sound (See sound-dev.) javax.swing core-libs (See core-libs-dev.) java.io java.io:serialization java.lang java.lang.invoke java.lang:class_loading java.lang:reflect java.math java.net java.nio (Discussed on nio-dev.) java.nio.charsets java.rmi java.sql java.sql:bridge java.text java.util java.util.concurrent java.util.jar java.util.logging java.util.regex java.util:collections java.util:i18n javax.annotation.processing javax.lang.model javax.naming (JNDI) javax.script javax.script:javascript javax.sql org.openjdk.jigsaw (See jigsaw-dev.) security-libs (See security-dev.) java.security javax.crypto (JCE: includes SunJCE/MSCAPI/UCRYPTO/ECC) javax.crypto:pkcs11 (JCE: PKCS11 only) javax.net.ssl (JSSE, includes javax.security.cert) javax.security javax.smartcardio javax.xml.crypto org.ietf.jgss org.ietf.jgss:krb5 other-libs corba corba:idl corba:orb corba:rmi-iiop javadb other (When no other subcomponent is more appropriate; use judiciously.)

Since these areas generally have dedicated teams working on them, it is easier to find bugs of interest if these bugs are grouped first by their cross-cutting component rather than by the affected technology. docs doclet guides hotspot release_notes tools tutorial embedded build hotspot libraries globalization locale-data translation performance hotspot libraries The list of subcomponents will no doubt grow over time, but my inclination is to resist that growth since the addition of each subcomponent makes the system as a whole more complicated and harder to use. When the system gets closer to being externalized, I plan to post more blog entries describing recommended use of various custom fields in the JDK project.

• Solaris 11 Live CD alapú telepítés

  - by AndrasF

  Az elozo részben megigért két telepítési eljárás helyett kénytelen vagyok ebben a bejegyzésben kizárólag a Live CD-s változattal foglalkozni. Korábban nem gondoltam, hogy ennek bemutatása is több, mint 50 képernyo kimenetet igényel, ezért változtatnom kellett a korábbi tervezeten. A Solaris 11 Live CD-s telepítés elsosorban az asztali (desktop) felhasználók igényeit veszi figyelembe és kizárólag x86-os architektúrájú gépeken támogatott (annak ellenére, hogy SPARC-os rendszerek is rendelkeznek grafikus kártyával - pl. T4-1).A folyamat két részre bontható: eloször a vendéggép kerül kialakítása VirtualBox környezetben, majd ezt követi a Solaris 11-es telepítése virtuális gépre. HCL és segédprogramok (DDT, DDU) Mielott telepíteni szeretnénk a Solaris operációs rendszert, célszeru tájékozódni fizikai rendszerünk támogatottságáról. Erre jól használható a már említett hardver kompatibilitási (HCL) lista, vagy az alábbi két segédprogram: Device Detection Tool Device Driver Utility Mindkét alkalmazás képes rendszerünk hardver komponenseit feltérképezni és ellenorizni azok meghajtóprogram (driver) ellátottságát. Eltérés köztük abban nyilvánul meg, hogy míg a DDT futtatásához Java szükséges, addig a DDU Solarist igényel. Ez utóbbiról a telepítés során röviden szó fog esni. Telepíto készletek letöltési helye Hálózati installációtól eltekintve (*) telepítokészletre van szükségünk, mely az alábbi oldalról töltheto le. Célszeru letöltenünk mindhárom állományt és a csomagokat tartalmazó ún. repository médiát (a következo felsorolás utolsó eleme) is: sol-11-1111-live-x86.iso sol-11-1111-text-x86.iso sol-11-1111-ai-x86.iso sol-11-1111-repo-full.iso Az elso három változat indítható USB formátumban is rendelkezésre áll - ekkor iso végzodés helyett usb található a fájlnevek végén. Rövid utalást az egyes készletek feladatáról az elozo blog bejegyzés tartalmaz (link). Amennyiben SPARC architektúrájú rendszerre szeretnénk a telepítést végezni, 'x86' helyett a 'sparc' szöveget tartalmazó állományokra lesz szükség. (*) - arra is lehetoség van, hogy AI készletrol történo indítás segítségével végezzük a hálózaton keresztül történo telepítést. Ez akkor fontos, ha célgépünkön nincs PXE (Preboot Execution Environment) boot támogatás. VirtualBox konfigurálás Külön fizikai eszköz felhasználása nélkül virtuális környezetben is használható a Solaris 11, mint vendéggép. A VirtualBox használatával erre kényelmes lehetoség kínálkozik. Gazdagépünknek (Windows, Unix, Linux) megfelelo telepíto program, vagy programcsomag (jelenleg a 4.1.16-os verzió a legfrissebb változat) és az installációt is taglaló felhasználói kézikönyv letöltheto a termék oldaláról. A sikeres telepítést követoen az alábbi lépések során jutunk el az új virtuális gép kialakulásáig: 1. A VBox indítása után a központi ablak megmutatja a már létezo virtuális gépeinket (Sol11demo, Sol11u1b07, Sol11.1B16, Sun_ZFS_Storage_7000) és az aktuálisan kiválasztott egyed (Sol11demo) fobb jellemzoit (megnevezés, memória mérete, virtuális tároló eszközök listája...stb.) 2. A New gombra kattintva elindul a virtuális gépet létrehozó segéd (wizard) 3. Ezt követoen nevet kell adnunk a vendéggépnek és ki kell választanunk az operációs rendszer típusát (beszédes név használata esetén a VirtualBox képes az operációs rendszer családját kiválasztani, nekünk pusztán csak verziót kell beállítanunk): adjuk meg Solaris11-et névként és válasszuk a 64bites változatot (feltéve, hogy gazdagépünk támogatja ezt) 4. Telepítéshez és a kezdeti lépések megtételéhez 1536MB memória tökéletesen megfelel (ez késobb módosítható az elvárások függvényében) 5. Fizikai társaihoz hasonlóan, egyetlen virtuális gép sem létezhet merevlemez (jelen esetben virtuális diszk) nélkül. Használhatunk egy már létezo területet (virtuális lemezt tartalmazó állomány), de létrehozhatunk egy nekünk tetszo új példányt is. Maradjunk ez utóbbinál (Create new hard disk)! 6. A lehetséges formátumok közül - az egyszeruség okán - éljünk a felkínált alaptípussal (VDI - VirtualBox Disk Image). 7. Létrehozás során a virtuális lemez készülhet egyidejuleg (Fixed size), vagy több lépésben dinamikusan (Dynamically allocated). Az elso változat sokkal kevésbé terheli a rendszert, a második elonye pedig a helytakarékosság. Válasszuk a fix méretu változatot. 8. Most már csak egyetlen adat ismeretlen a VirtualBox számára, mégpedig a létrehozásra kerülo virtuális lemez nagysága. 8GB-os terület jelen esetben alkalmas az ismerkedés elkezdéséhez. 9. Amennyiben minden beállítást helyesen adtunk meg, a Create gomb megnyomása után elindul a virtuális lemez létrehozása. 10. Ez a muvelet a megadott adatoktól függoen néhány perc alatt befejezodik. 11. Hasonló megerosítés (Create gomb aktiválása) után elkezdodik a kért virtuális gép létrehozása is. 12. Sikeres végrehajtás után az új vitruális gép közvetlenül megjelenik a központi ablak baloldali listáján a rendelkezésre álló virtuális gépek közt. A blog bejegyzés folyamatosan frissül...a rész fennmaradó tartalma hamarosan felkerül az oldalra.

• Configure IPv6 on your Linux system (Ubuntu)

  After the presentation on IPv6 at the first event of the Emtel Knowledge Series and some recent discussion on social media networks with other geeks and Linux interested IT people here in Mauritius, I thought that I should give it a try (finally) and tweak my local network infrastructure. Honestly, I have been to busy with contractual project work and it never really occurred to me to set up IPv6 in my LAN. Well, the following paragraphs are going to shed some light on those aspects of modern computer and network technology. This is the first article in a series on IPv6 configuration: Configure IPv6 on your Linux system DHCPv6: Provide IPv6 information in your local network Enabling DNS for IPv6 infrastructure Accessing your web server via IPv6 Piece of advice: This is based on my findings on the internet while reading other people's helpful articles and going through a couple of man-pages on my local system. Let's embrace IPv6 The basic configuration on Linux is actually very simple as the kernel, operating system, and user-space programs support that protocol natively. If your system is ready to go for IP (aka: IPv4), then you are good to go for anything else. At least, I didn't have to install any additional packages on my system(s). We are going to assign a static IPv6 address to the system. Hence, we have to modify the definition of interfaces and check whether we have an inet6 entry specified. Open your favourite text editor and check the following entries (it should be at least similar to this): $ sudo nano /etc/network/interfaces auto eth0# IPv4 configurationiface eth0 inet static  address 192.168.1.2  network 192.168.1.0  netmask 255.255.255.0  broadcast 192.168.1.255# IPv6 configurationiface eth0 inet6 static  pre-up modprobe ipv6  address 2001:db8:bad:a55::2  netmask 64 Of course, you might have to adjust your interface device (eth0) or you might be interested to have multiple directives for additional devices (eth1, eth2, etc.). The auto instruction takes care that your device is enabled and configured during the booting phase. The use of the pre-up directive depends on your kernel configuration but in most scenarios this might be an optional line. Anyways, it doesn't hurt to have it enabled after all - just to be on the safe side. Next, either restart your network subsystem like so: $ sudo service networking restart Or you might prefer to do it manually with identical parameters, like so: $ sudo ifconfig eth0 inet6 add 2001:db8:bad:a55::2/64 In case that you're logged in remotely into your PC (ie. via ssh), it is highly advised to opt for the second choice and add the device manually. You can check your configuration afterwards with one of the following commands (depends on whether it is installed): $ sudo ifconfig eth0eth0      Link encap:Ethernet  HWaddr 00:21:5a:50:d7:94            inet addr:192.168.160.2  Bcast:192.168.160.255  Mask:255.255.255.0          inet6 addr: fe80::221:5aff:fe50:d794/64 Scope:Link          inet6 addr: 2001:db8:bad:a55::2/64 Scope:Global          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1 $ sudo ip -6 address show eth03: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qlen 1000    inet6 2001:db8:bad:a55::2/64 scope global        valid_lft forever preferred_lft forever    inet6 fe80::221:5aff:fe50:d794/64 scope link        valid_lft forever preferred_lft forever In both cases, it confirms that our network device has been assigned a valid IPv6 address. That's it in general for your setup on one system. But of course, you might be interested to enable more services for IPv6, especially if you're already running a couple of them in your IP network. More details are available on the official Ubuntu Wiki. Continue to configure your network to provide IPv6 address information automatically in your local infrastructure.

• Wildcards!

  - by Tim Dexter

  Yes, its been a while, Im sorry, mumble, mumble ... no excuses. Well other than its been, as my son would say 'hecka busy.' On a brighter note I see Kan has been posting some cool stuff in my absence, long may he continue! I received a question today asking about using a wildcard in a template, something like: <?if:INVOICE = 'MLP*'?> where * is the wildcard Well that particular try does not work but you can do it without building your own wildcard function. XSL, the underpinning language of the RTF templates, has some useful string functions - you can find them listed here. I used the starts-with function to achieve a simple wildcard scenario but the contains can be used in conjunction with some of the others to build something more sophisticated. Assume I have a a list of friends and the amounts of money they owe me ... Im very generous and my interest rates a pretty competitive :0) <ROWSET> <ROW> <NAME>Andy</NAME> <AMT>100</AMT> </ROW> <ROW> <NAME>Andrew</NAME> <AMT>60</AMT> </ROW> <ROW> <NAME>Aaron</NAME> <AMT>50</AMT> </ROW> <ROW> <NAME>Alice</NAME> <AMT>40</AMT> </ROW> <ROW> <NAME>Bob</NAME> <AMT>10</AMT> </ROW> <ROW> <NAME>Bill</NAME> <AMT>100</AMT> </ROW> Now, listing my friends is easy enough <for-each:ROW> <NAME> <AMT> <end for-each> but lets say I just want to see all my friends beginning with 'A'. To do that I can use an XPATH expression to filter the data and tack it on to the for-each expression. This is more efficient that using an 'if' statement just inside the for-each. <?for-each:ROW[starts-with(NAME,'A')]?> will find me all the A's. The square braces denote the start of the XPATH expression. starts-with is the function Im calling and Im passing the value I want to check i.e. NAME and the string Im looking for. Just substitute in the characters you are looking for. You can of course use the function in a if statement too. <?if:starts-with(NAME,'A')?><?attribute@incontext:color;'red'?><?end if?> Notice I removed the square braces, this will highlight text red if the name begins with an 'A' You can even use the function to do conditional calculations: <?sum (AMT[starts-with(../NAME,'A')])?> Sum only the amounts where the name begins with an 'A' Notice the square braces are back, its a function we want to apply to the AMT field. Also notice that we need to use ../NAME. The AMT and NAME elements are at the same level in the tree, so when we are at the AMT level we need the ../ to go up a level to then come back down to test the NAME value. I have built out the above functions in a sample template here. Huge prizes for the first person to come up with a 'true' wildcard solution i.e. if NAME like '*im*exter* demand cash now!

• Integrating Windows Form Click Once Application into SharePoint 2007 &ndash; Part 2 of 4

  - by Kelly Jones

  In my last post, I explained why we decided to use a Click Once application to solve our business problem. To quickly review, we needed a way for our business users to upload documents to a SharePoint 2007 document library in mass, set the meta data, set the permissions per document, and to do so easily. Let’s look at the pieces that make up our solution.  First, we have the Windows Form application.  This app is deployed using Click Once and calls SharePoint web services in order to upload files and then calls web services to set the meta data (SharePoint columns and permissions).  Second, we have a custom action.  The custom action is responsible for providing our users a link that will launch the Windows app, as well as passing values to it via the query string.  And lastly, we have the web services that the Windows Form application calls.  For our solution, we used both out of the box web services and a custom web service in order to set the column values in the document library as well as the permissions on the documents. Now, let’s look at the technical details of each of these pieces.  (All of the code is downloadable from here: )   Windows Form application deployed via Click Once The Windows Form application, called “Custom Upload”, has just a few classes in it: Custom Upload -- the form FileList.xsd -- the dataset used to track the names of the files and their meta data values SharePointUpload -- this class handles uploading the file SharePointUpload uses an HttpWebRequest to transfer the file to the web server. We had to change this code from a WebClient object to the HttpWebRequest object, because we needed to be able to set the time out value.  public bool UploadDocument(string localFilename, string remoteFilename) { bool result = true; //Need to use an HttpWebRequest object instead of a WebClient object // so we can set the timeout (WebClient doesn't allow you to set the timeout!) HttpWebRequest req = (HttpWebRequest)WebRequest.Create(remoteFilename); try { req.Method = "PUT"; req.Timeout = 60 * 1000; //convert seconds to milliseconds req.AllowWriteStreamBuffering = true; req.Credentials = System.Net.CredentialCache.DefaultCredentials; req.SendChunked = false; req.KeepAlive = true; Stream reqStream = req.GetRequestStream(); FileStream rdr = new FileStream(localFilename, FileMode.Open, FileAccess.Read); byte[] inData = new byte[4096]; int bytesRead = rdr.Read(inData, 0, inData.Length); while (bytesRead > 0) { reqStream.Write(inData, 0, bytesRead); bytesRead = rdr.Read(inData, 0, inData.Length); } reqStream.Close(); rdr.Close(); System.Net.HttpWebResponse response = (HttpWebResponse)req.GetResponse(); if (response.StatusCode != HttpStatusCode.OK && response.StatusCode != HttpStatusCode.Created) { String msg = String.Format("An error occurred while uploading this file: {0}\n\nError response code: {1}", System.IO.Path.GetFileName(localFilename), response.StatusCode.ToString()); LogWarning(msg, "2ACFFCCA-59BA-40c8-A9AB-05FA3331D223"); result = false; } } catch (Exception ex) { LogException(ex, "{E9D62A93-D298-470d-A6BA-19AAB237978A}"); result = false; } return result; } The class also contains the LogException() and LogWarning() methods. When the application is launched, it parses the query string for some initial values.  The query string looks like this: string queryString = "Srv=clickonce&Sec=N&Doc=DMI&SiteName=&Speed=128000&Max=50"; This Srv is the path to the server (my Virtual Machine is name “clickonce”), the Sec is short for security – meaning HTTPS or HTTP, the Doc is the shortcut for which document library to use, and SiteName is the name of the SharePoint site.  Speed is used to calculate an estimate for download speed for each file.  We added this so our users uploading documents would realize how long it might take for clients in remote locations (using slow WAN connections) to download the documents. The last value, Max, is the maximum size that the SharePoint site will allow documents to be.  This allowed us to give users a warning that a file is too large before we even attempt to upload it. Another critical piece is the meta data collection.  We organized our site using SharePoint content types, so when the app loads, it gets a list of the document library’s content types.  The user then select one of the content types from the drop down list, and then we query SharePoint to get a list of the fields that make up that content type.  We used both an out of the box web service, and one that we custom built, in order to get these values. Once we have the content type fields, we then add controls to the form.  Which type of control we add depends on the data type of the field.  (DateTime pickers for date/time fields, etc)  We didn’t write code to cover every data type, since we were working with a limited set of content types and field data types. Here’s a screen shot of the Form, before and after someone has selected the content types and our code has added the custom controls:     The other piece of meta data we collect is the in the upper right corner of the app, “Users with access”.  This box lists the different SharePoint Groups that we have set up and by checking the boxes, the user can set the permissions on the uploaded documents. All of this meta data is collected and submitted to our custom web service, which then sets the values on the documents on the list.  We’ll look at these web services in a future post. In the next post, we’ll walk through the Custom Action we built.
