• Talking JavaOne with Rock Star Raghavan Srinivas

  - by Janice J. Heiss

  Raghavan Srinivas, affectionately known as “Rags,” is a two-time JavaOne Rock Star (from 2005 and 2011) who, as a Developer Advocate at Couchbase, gets his hands dirty with emerging technology directions and trends. His general focus is on distributed systems, with a specialization in cloud computing. He worked on Hadoop and HBase during its early stages, has spoken at conferences world-wide on a variety of technical topics, conducted and organized Hands-on Labs and taught graduate classes.He has 20 years of hands-on software development and over 10 years of architecture and technology evangelism experience and has worked for Digital Equipment Corporation, Sun Microsystems, Intuit and Accenture. He has evangelized and influenced the architecture of numerous technologies including the early releases of JavaFX, Java, Java EE, Java and XML, Java ME, AJAX and Web 2.0, and Java Security.Rags will be giving these sessions at JavaOne 2012: CON3570 -- Autosharding Enterprise to Social Gaming Applications with NoSQL and Couchbase CON3257 -- Script Bowl 2012: The Battle of the JVM-Based Languages (with Guillaume Laforge, Aaron Bedra, Dick Wall, and Dr Nic Williams) Rags emphasized the importance of the Cloud: “The Cloud and the Big Data are popular technologies not merely because they are trendy, but, largely due to the fact that it's possible to do massive data mining and use that information for business advantage,” he explained. I asked him what we should know about Hadoop. “Hadoop,” he remarked, “is mainly about using commodity hardware and achieving unprecedented scalability. At the heart of all this is the Java Virtual Machine which is running on each of these nodes. The vision of taking the processing to where the data resides is made possible by Java and Hadoop.” And the most exciting thing happening in the world of Java today? “I read recently that Java projects on github.com are just off the charts when compared to other projects. It's exciting to realize the robust growth of Java and the degree of collaboration amongst Java programmers.” He encourages Java developers to take advantage of Java 7 for Mac OS X which is now available for download. At the same time, he also encourages us to read the caveats. Originally published on blogs.oracle.com/javaone.

• How to open a VirtualBox (.VDI) Virtual Machine

  - by [email protected]

   How to open a .VDI Virtual MachineSometimes someone share with us one Virtual machine with extension .VDI, after that we can wonder how and what with?Well the answer is... It is a VirtualBox - Virtual Machine. If you have not downloaded it you can do this easily, just follow this post.http://listeningoracle.blogspot.com/2010/04/que-es-virtualbox.htmlorhttp://oracleoforacle.wordpress.com/2010/04/14/ques-es-virtualbox/Ok, Now with VirtualBox Installed open it and proceed with the following:1. Open the Virtual File Manager. 2. Click on Actions ? Add and select the .VDI fileClick "Ok"3.  A new Virtual machine will be displayed, (in this Case, an OEL5 32GB Virtual Machine is available.)4. This step is important. Once you have open the settings, under General option click the advanced settings. Here you must change the default directory to save your Snapshots; my recommendation set it to the same directory where the .Vdi file is. Otherwise you can have the same Virtual Machine and its snapshots in different paths.5. Now Click on System, and proceed to assign the correct memory and define the processors for the Virtual machine. Note: Enable  "Enable IO APIC" if you are planning to assign more than one CPU to the Virtual Machine.6. Associated the storage disk to the Virtual machineThe disk must be selected as IDE Primary Master. 7. Well you can verify the other options, but with these changes you will be able to start the VM. Note: Sometime the VM owner may share some instructions, if so follow his instructions.8. Click Ok and Push Start Button, and enjoy your Virtual Machine

• xcopy file, suppress &ldquo;Does xxx specify a file name&hellip;&rdquo; message

  - by MarkPearl

  Today we had an interesting problem with file copying. We wanted to use xcopy to copy a file from one location to another and rename the copied file but do this impersonating another user. Getting the impersonation to work was fairly simple, however we then had the challenge of getting xcopy to work. The problem was that xcopy kept prompting us with a prompt similar to the following… Does file.xxx specify a file name or directory name on the target (F = file, D = directory)? At which point we needed to press ‘Y’. This seems to be a fairly common challenge with xcopy, as illustrated by the following stack overflow link… One of the solutions was to do the following… echo f | xcopy /f /y srcfile destfile This is fine if you are running from the command prompt, but if you are triggering this from c# how could we daisy chain a bunch of commands…. The solution was fairly simple, we eventually ended up with the following method… public void Copy(string initialFile, string targetFile) { string xcopyExe = @"C:\windows\system32\xcopy.exe"; string cmdExe = @"C:\windows\system32\cmd.exe"; ProcessStartInfo p = new ProcessStartInfo(); p.FileName = cmdExe; p.Arguments = string.Format(@"/c echo f | {2} {0} {1} /Y", initialFile, targetFile, xcopyExe); Process.Start(p); } Where we wrapped the commands we wanted to chain as arguments and instead of calling xcopy directly, we called cmd.exe passing xcopy as an argument.

• SEO Implications of creating Niche Product Blogs vs Main Company Blog with Categories.

  - by Frank

  Our company has a dilemma that I am hoping the users of Pro WebMasters can help us with. Right now as it stands we create a seperate website for each product that we sell. We also have our corporate site which lists each of these brands. For Example: www.Apple.com < --- main company site www.Ipad.com <--- Product www.Iphone.com <--- Product www.Imac.com <-- Product We are looking to build a wordpress blog mainly for the purpose of increasing our SEO rank. Here are our two options: SINGLE BLOG - On Our Corporate Domain http://apple.com/blog Each post is categoried http://apple.com/category/ipad/ipad-5-realeasd.htm Easier to manage than multiple blogs More content since its listing about all our products. ONE BLOG PER PRODUCT - on each site http://ipad.com/blog Each product has its own blog with only its own articles Harder to manage, but does it benefit SEO? Can the team here tell me the SEO benefits of either approach? Similar to Apple all the products our company sells are loosely related. Although its not likely that a customer of product A would be interested in product B.

• How to deal with static utility classes when designing for testability

  - by Benedikt

  We are trying to design our system to be testable and in most parts developed using TDD. Currently we are trying to solve the following problem: In various places it is necessary for us to use static helper methods like ImageIO and URLEncoder (both standard Java API) and various other libraries that consist mostly of static methods (like the Apache Commons libraries). But it is extremely difficult to test those methods that use such static helper classes. I have several ideas for solving this problem: Use a mock framework that can mock static classes (like PowerMock). This may be the simplest solution but somehow feels like giving up. Create instantiable wrapper classes around all those static utilities so they can be injected into the classes that use them. This sounds like a relatively clean solution but I fear we'll end up creating an awful lot of those wrapper classes. Extract every call to these static helper classes into a function that can be overridden and test a subclass of the class I actually want to test. But I keep thinking that this just has to be a problem that many people have to face when doing TDD - so there must already be solutions for this problem. What is the best strategy to keep classes that use these static helpers testable?

• Cross-Platform Mobile Development With Mono for Android and MonoTouch

  - by Wallym

  Many years ago, in fact pre-Java, I remember a hallway discussion about the desire to write a single application that could easily run across various platforms. At the time, we were only worried about writing applications on Windows 3.1 and Mac OS 7.x. There were many discussions about windows, user interface concepts, and specifically a rather long discussion as to whether Mac users would accept a Mac application that didn't have balloon help. Thankfully, the marketplace answered this question for us with the Windows API winning the battle.A similar set of questions is currently going on in the mobile world. Unfortunately, at this point in time, there is currently no winning API and none currently in sight. What's a developer to do? Here are some questions that developers have (and there are many more):How can mobile developers target Android and the iPhone with the same code?How can .NET developers share their code across Android, iPhone and other platforms?How can developers give applications the look and feel of the specific platform and still allow as much code as possible to be shared?Mobile devices share many common features, such as cameras, accelerometers, and address books. How can we take advantage of them in a platform independent way and still give the users the look of every other application running on their platform?In this article, we'll look at some solutions to these cross-platform and code-sharing questions between Mono for Android, MonoTouch and the .NET Framework available to developers.

• Apache httpd.conf handle multiple domains to run the same application

  - by John Stewart

  So what we are looking for is the ability to do the following: We have an application that can load certain settings based on the domain that it is being accessed from. So if you come from xyz.com we show a different logo and if you come from abc.com we show a different logo. The code is the same, running from same server just detects the domain on the run Now we want to get a dedicated server (any suggestions?) that will enable us to point all the doamins that we want to this server (we change the DNS for the domains to that of our server) and then when the user goes to a certain domain they run the same application. Now as far as I can understand we will need to create a "VirtualHost" in apache to handle this. Can we create a wildcard virtualhost that catches all the domains? I am not an expert with Apache at all. So please forgive if this comes out to be a silly question. Any detailed help would be great. Thanks

• Ubuntu 10.04 server crash

  - by Jamie

  I'm running an Ubuntu 10.04 (x64) as a web/mysql server. The server became unresponsive to SSH, Ping, HTTP etc. and the technician with physical access to the machine sent me this screengrab here: http://img442.imageshack.us/img442/389/img00062201012211332.jpg from the connected monitor before he rebooted (and the situation is fixed). I'm not sure what log this information is kept in as I can't find the text after checking the logs after reboot. Can anyone help me to investigate what happened to try and ensure it doesn't happen again? Thanks

• How to share media stored in an attached drive using Windows Media Player?

  - by David

  We've got a Windows 7 PC with a Windows Media Player music library that includes both files on the internal hard drive and files on a USB-attached hard drive. When we browse this library from another Windows Media Player (on another Windows 7 machine) we see only the files residing on the library host's internal drive. The files residing on the attached drive don't show up at all, yet on the host they appear undistinguished within the library. Is there a configuration change we can make to cause the attached files to be shared properly? We've turned on read-sharing for "Everyone" on the USB drive, but that hasn't helped. Also it might be worth noting that this issue behaves the same way for us if the client machine is a Playstation 3.

• How do I manage the technical debate over WCF vs. Web API?

  - by Saeed Neamati

  I'm managing a team of like 15 developers now, and we are stuck at a point on choosing the technology, where the team is broken into two completely opposite teams, debating over usage of WCF vs. Web API. Team A which supports usage of Web API, brings forward these reasons: Web API is just the modern way of writing services (Wikipedia) WCF is an overhead for HTTP. It's a solution for TCP, and Net Pipes, and other protocols WCF models are not POCO, because of [DataContract] & [DataMember] and those attributes SOAP is not as readable and handy as JSON SOAP is an overhead for network compared to JSON (transport over HTTP) No method overloading Team B which supports the usage of WCF, says: WCF supports multiple protocols (via configuration) WCF supports distributed transactions Many good examples and success stories exist for WCF (while Web API is still young) Duplex is excellent for two-way communication This debate is continuing, and I don't know what to do now. Personally, I think that we should use a tool only for its right place of usage. In other words, we'd better use Web API, if we want to expose a service over HTTP, but use WCF when it comes to TCP and Duplex. By searching the Internet, we can't get to a solid result. Many posts exist for supporting WCF, but on the contrary we also find people complaint about it. I know that the nature of this question might sound arguable, but we need some good hints to decide. We're stuck at a point where choosing a technology by chance might make us regret it later. We want to choose with open eyes. Our usage would be mostly for web, and we would expose our services over HTTP. In some cases (say 5 to 10 percent) we might need distributed transactions though. What should I do now? How do I manage this debate in a constructive way?

• Interactive Reporting with BI Publisher 11G

  - by kanichiro.nishida

  One of the new features that came out with BI Publisher 11G and made me really excited about is the Interactive Viewer, which allows you to interact with the data presented in the reports and gain more insights about the data. You can have as many Table, Chart, Pivot Table, Gauge components in a single report and all of them are linked together so that you can click on any data point on the components such as Chart, Pivot Table, Gauge, and that would refresh other components in the report to reflect the selection without refreshing the whole report or page. No longer you need to navigate to another report or open other reports to see related data or drill down to the detail data. It’s all there within a single report. Well, sounds cliché but really this is a typical case of ‘seeing is believing’, so instead of reading I would love you guys to take a look so I’ve recorded the following video. Please take a look !   The above video shows you the power of the BI Publisher Interactive Viewer with a real data from San Francisco Airport. The lists shown at the top or the left are one of the new features that we’ll be introducing in coming future very soon, but everything else is there with 11.1.1.3. So why not start today ? And please share your feedback with us!

• Is it possible to skip .rvmrc confirmation?

  - by Viacheslav Molokov

  We are using RVM for managing Ruby installations and environments. Usually we are using this .rvmrc script: #!/bin/bash if [ ! -e '.version' ]; then VERSION=`pwd | sed 's/[a-z/-]//g'` echo $VERSION > .version rvm gemset create $VERSION fi VERSION=`cat .version` rvm use 1.9.2@$VERSION This script forces RVM to create new gem environment for each our project/version. But each time we was deploying new version RVM asks us to confirm new .rvmrc file. When we cd to this directory first time, we are getting something like: =============================================================== = NOTICE: = =============================================================== = RVM has encountered a not yet trusted .rvmrc file in the = = current working directory which may contain nasty code. = = = = Examine the contents of this file to be sure the contents = = are good before trusting it! = = = = Press 'q' to exit the reader when finished reading the file = =============================================================== (press enter to continue when ready) This is not as bad for development environments, but with auto deploy it require to manually confirm each new version on each server. Is it possible to skip this confirmation?

• Other user SSHed from my hardware

  - by Alex

  While logged into our HPC cluster I used w to check out who else was logged in. I happened to notice that it looks like there's another user logged in from my (personal) computer; 19:04:47 up 40 days, 6:39, 44 users, load average: 0.10, 0.14, 0.18 USER TTY FROM LOGIN@ IDLE JCPU PCPU WHAT ME pts/4 zerg.neuron12. 18:55 0.00s 0.09s 0.04s w SOMEONE_ELSE pts/35 zerg.neuron12. Sat14 2:27m 0.08s 0.08s -bash Is this something I should be worried out - I tried to kill the other session but had a permission denied message. Is it possible we just both have the same hardware name? I'd have thought that if this were the case the server would give one of us a different name (e.g. zerg1) when we logged in to prevent confusion. This is not an area I have any experience with, so any advice would be greatly appreciated!

• SQL SERVER – Weekly Series – Memory Lane – #039

  - by Pinal Dave

  Here is the list of selected articles of SQLAuthority.com across all these years. Instead of just listing all the articles I have selected a few of my most favorite articles and have listed them here with additional notes below it. Let me know which one of the following is your favorite article from memory lane. 2007 FQL – Facebook Query Language Facebook list following advantages of FQL: Condensed XML reduces bandwidth and parsing costs. More complex requests can reduce the number of requests necessary. Provides a single consistent, unified interface for all of your data. It’s fun! UDF – Get the Day of the Week Function The day of the week can be retrieved in SQL Server by using the DatePart function. The value returned by the function is between 1 (Sunday) and 7 (Saturday). To convert this to a string representing the day of the week, use a CASE statement. UDF – Function to Get Previous And Next Work Day – Exclude Saturday and Sunday While reading ColdFusion blog of Ben Nadel Getting the Previous Day In ColdFusion, Excluding Saturday And Sunday, I realize that I use similar function on my SQL Server Database. This function excludes the Weekends (Saturday and Sunday), and it gets previous as well as next work day. Complete Series of SQL Server Interview Questions and Answers Data Warehousing Interview Questions and Answers – Introduction Data Warehousing Interview Questions and Answers – Part 1 Data Warehousing Interview Questions and Answers – Part 2 Data Warehousing Interview Questions and Answers – Part 3 Data Warehousing Interview Questions and Answers Complete List Download 2008 Introduction to Log Viewer In SQL Server all the windows event logs can be seen along with SQL Server logs. Interface for all the logs is same and can be launched from the same place. This log can be exported and filtered as well. DBCC SHRINKFILE Takes Long Time to Run If you are DBA who are involved with Database Maintenance and file group maintenance, you must have experience that many times DBCC SHRINKFILE operations takes a long time but any other operations with Database are relatively quicker. mssqlsystemresource – Resource Database The purpose of resource database is to facilitates upgrading to the new version of SQL Server without any hassle. In previous versions whenever version of SQL Server was upgraded all the previous version system objects needs to be dropped and new version system objects to be created. 2009 Puzzle – Write Script to Generate Primary Key and Foreign Key In SQL Server Management Studio (SSMS), there is no option to script all the keys. If one is required to script keys they will have to manually script each key one at a time. If database has many tables, generating one key at a time can be a very intricate task. I want to throw a question to all of you if any of you have scripts for the same purpose. Maximizing View of SQL Server Management Studio – Full Screen – New Screen I had explained the following two different methods: 1) Open Results in Separate Tab - This is a very interesting method as result pan shows up in a different tab instead of the splitting screen horizontally. 2) Open SSMS in Full Screen - This works always and to its best. Not many people are aware of this method; hence, very few people use it to enhance performance. 2010 Find Queries using Parallelism from Cached Plan T-SQL script gets all the queries and their execution plan where parallelism operations are kicked up. Pay attention there is TOP 10 is used, if you have lots of transactional operations, I suggest that you change TOP 10 to TOP 50 This is the list of the all the articles in the series of computed columns. SQL SERVER – Computed Column – PERSISTED and Storage This article talks about how computed columns are created and why they take more storage space than before. SQL SERVER – Computed Column – PERSISTED and Performance This article talks about how PERSISTED columns give better performance than non-persisted columns. SQL SERVER – Computed Column – PERSISTED and Performance – Part 2 This article talks about how non-persisted columns give better performance than PERSISTED columns. SQL SERVER – Computed Column and Performance – Part 3 This article talks about how Index improves the performance of Computed Columns. SQL SERVER – Computed Column – PERSISTED and Storage – Part 2 This article talks about how creating index on computed column does not grow the row length of table. SQL SERVER – Computed Columns – Index and Performance This article summarized all the articles related to computed columns. 2011 SQL SERVER – Interview Questions and Answers – Frequently Asked Questions – Data Warehousing Concepts – Day 21 of 31 What is Data Warehousing? What is Business Intelligence (BI)? What is a Dimension Table? What is Dimensional Modeling? What is a Fact Table? What are the Fundamental Stages of Data Warehousing? What are the Different Methods of Loading Dimension tables? Describes the Foreign Key Columns in Fact Table and Dimension Table? What is Data Mining? What is the Difference between a View and a Materialized View? SQL SERVER – Interview Questions and Answers – Frequently Asked Questions – Data Warehousing Concepts – Day 22 of 31 What is OLTP?

Look at the simple question – ‘What is the toughest challenge you have faced in your present job and how did you handle it’? and its various answers. Each answer has its own story. SQL SERVER – Interview Questions and Answers – Guest Post by Rick Morelan – Day 27 of 31 Rick Morelan of Joes2Pros has written an excellent blog post on the subject how to find top N values. Most people are fully aware of how the TOP keyword works with a SELECT statement. After years preparing so many students to pass the SQL Certification I noticed they were pretty well prepared for job interviews too. Yes, they would do well in the interview but not great. There seemed to be a few questions that would come up repeatedly for almost everyone. Rick addresses similar questions in his lucid writing skills. 2012 Observation of Top with Index and Order of Resultset SQL Server has lots of things to learn and share. It is amazing to see how people evaluate and understand different techniques and styles differently when implementing. The real reason may be absolutely different but we may blame something totally different for the incorrect results. Read the blog post to learn more. How do I Record Video and Webcast How to Convert Hex to Decimal or INT Earlier I asked regarding a question about how to convert Hex to Decimal. I promised that I will post an answer with Due Credit to the author but never got around to post a blog post around it. Read the original post over here SQL SERVER – Question – How to Convert Hex to Decimal. Query to Get Unique Distinct Data Based on Condition – Eliminate Duplicate Data from Resultset The natural reaction will be to suggest DISTINCT or GROUP BY. However, not all the questions can be solved by DISTINCT or GROUP BY. Let us see the following example, where a user wanted only latest records to be displayed. Let us see the example to understand further.

• My old Conchango blog posts are currently not accessible

  - by jamiet

  Some of you reading this may be aware that I used to blog at http://blogs.conchango.com/jamiethomson. That URL later changed to http://consultingblogs.emc.com/jamiethomson after Conchango (my employer) got taken over by EMC. In my last post on that site: I stated that I had 676 blog posts on that site. Unfortunately, as of today, those 676 posts are inaccessible. If you try to get to http://consultingblogs.emc.com/jamiethomson today you will see this: I am not the only one affected either; it seems that EMC have taken the same action for many blog sites of my old colleagues (e.g. http://consultingblogs.emc.com/merrickchaffer is also inaccessible). Early indications are that EMC have removed all blog posts by any former employees although that is yet to be confirmed.   A few of us former employees are endeavouring to get this situation rectified so watch this space. I am aware that many people in the SSIS community still refer to those old blog posts so please be aware that any attempt to access any of them will be futile for the foreseeable future. @Jamiet

• Integrating Social, Marketing, and Loyalty to Deliver Great Customer Experiences

  - by Charles Knapp

  Eighty nine percent of consumers quit a brand after one bad experience. With the high cost of acquiring new customers, what can brand leaders do? At the Loyalty World Conference this week in London, global business leaders such as the co-founder of Ben & Jerry’s shared the latest in how to retain customers and boost advocacy. Melissa Boxer and Sundar Swaminathan of Oracle shared that by taking an outside-in approach, you can deliver a differentiated, loyalty-building experience throughout the customer lifecycle, from researching and selecting through to using and recommending. To transform customer experiences, you need to integrate your brand’s social, marketing, and loyalty functions from the commonplace silos. Three key strategies: Know more and understand, unifying and capturing insights across touch points to better understand who to serve, how to serve, and when to serve.  Connect and engage across social and traditional channels, empowering a relationship ecosystem between social communities, customers, and employees. Make the personalized experience easy and rewarding. Visit us on twitter.com/oraclecrm to learn more useful highlights from the #lwconf conference.

• Java 7 update 6 installation fails on Windows 7 when Chrome is default browser

  - by ali1234

  I am configuring a brand new Lenovo U410 system with Windows 7 Home Premium for a user. I received the system direct from the shop. As part of the configuration I installed Java using the online installer. This worked correctly. Later, due to a mistake I made, I needed to restore the system to factory default. The factory default FORMATS C:\ and puts back (supposedly) the exact factory configuration. However, after doing this, I was no longer able to install Java successfully using the same method I used before. Now, whenever I attempt to use the online Java installer, the following happens. First of all, a window always appears "Welcome to Java", "Downloading Java Installer...". After short time this window disappears and then one of three things happens: The very first time I do this after doing a factory reset, I get a Windows error report, which contains this information: Application Name: JavaSetup7u5.exe Application Version: 7.0.50.6 Application Timestamp: 4feacd84 Fault Module Name: JavaIC.dll Fault Module Version: 9.9.9.9 Fault Module Timestamp: 4f2343d6 Exception Offset: 000052cb Exception Code: c0000417 Exception Data: 00000000 OS Version: 6.1.7600.2.0.0.768.3 Locale ID: 1033 Additional Information 1: 773c Additional Information 2: 773cd78cf06816f8246f359fa270f3bb Additional Information 3: f51a Additional Information 4: f51aaea7d22f36fa9e3a626b5a5cd1c3 2. Subsequent runs produce either this error message: "Error: Java(TM) installer - Downloaded file C:\Users\\AppData\Local\Temp\fx-runtime.exe is corrupt." or Nothing happens at all. I Believe this is a red herring. Running the installer again causes a different error because the files were downloaded and the installer crashed before it could clean up. This isn't the actual problem, as when this happens the installer deletes the downloaded files, and then when you run it for the third time, it downloads everything again and does the javaic.dll crash. I suspect the downloader is appending to the existing files or something, causing the corruption. I have tried all of the above as Administrator and as a normal user. I have tried reseting the system to factory defaults several times. I have tried downloading with Chrome and Internet Explorer 9. I have tried uninstalling all anti-virus software and disabling the windows firewall entirely. The only thing which makes a difference is running the installer in Windows XP compatibility mode, which allows the installation to complete. I know I can workaround this error by using the offline installer so please don't post that as an answer. I am looking for an explanation of the root cause. Additionally, if I use the offline installer, the updater does not work. The updater also does not work if I install in XP mode. The updater fails because it works by just downloading the newest online setup and running it. Also remember that the installers are digitally signed. The signitures verify correctly so there is no way in hell that this is caused by corrupted downloads. Some theories I have: The Java setup files on java.com actually changed in between the first successful install and my later attempts. Seems unlikely as none of the version numbers have changed. However, I have seen a couple of reports of this error which showed up in the past 24 hours. This looks like the most likely explanation right now: http://www.oracle.com/us/corporate/press/1735645 - Oracle released 7 update 6 two days ago. Careful inspection of the installers reveal that they are in fact attempting to download .6, not .5 as the download page claims. Not actually correct. Only the update tool tries to install 7u6. The online installer still tries 7u5. However, 7u6 being released two days ago is too much of a coincidence to ignore. Update: The 7u6 online installer is available from Oracle technetwork. It crashes in exactly the same way. The factory reset software uses GMT-8 and I am on GMT-1. As a result, after factory reset, any software which cares to check would think that the system was restored 7 hours in the future, due to Window's awful policy of storing local time in the system clock. This could be confusing a certificate check or similar. Update: I discovered that this does cause Windows Update to fail. The workaround, setting the clock back before starting factory reset, does not enable Java to install correctly. The factory reset image isn't really the same as what is installed in the main partition when you buy the system. Naughty Lenovo. The installer appears to crash while installing or displaying something to do with the Ask.com toolbar. That seems to be what javaic.dll does. Microsoft Tuesday was the 14th. Some update in that could be causing this. However, I'm factory reseting the machine every time, so unless the patches get slipstreamed into the recovery image, or there is some mechanism by which they get silently installed even if updates are disabled, then I don't see how this can be the cause. Major breakthrough: The default browser on Lenovo systems is Google Chrome. I noticed that the JavaIC.dll "sponsor check" actually does a check on your default browser in order to decide which sponsor ad to display. Normally that would get you the Ask toolbar on IE9. But that toolbar doesn't work on Chrome, and so the installer tries to display a different ad. The different ad is what causes the crash. Changing the default browser to IE9 allows the installer to run correctly. So this looks like a genuine bug in the sponsor ad code in the installer, caused by a combination of Google Chrome default browser and not being in the US. (Installer also checks your location using IP geolocation service and displays different ads based on that.)

• Windows 7 Connection Sharing unable to access some sites

  - by Kristopher Ives

  I have a pretty sad networking situation that involves connecting to an open Wireless network and sharing that connection to an Ethernet that is plugged into a Linksys router. This has been done with XP and Windows 7, and it works great with XP. The problem with Windows 7 is that only some DNS will work. I don't know if it's been poisoned on the network above us (which we have no control over), but we've tried clearing the DNS cache as well as moving to using Google's DNS servers (8.8.8.8, 8.8.4.4). Here is a really quick list of sites that won't respond to DNS requests at all via dig, although if I get the IP address I can ping them: facebook.com yuilibrary.com twitter.com A lot of sites do work though. Anyone have an idea? It may be a subnet problem? If anyone wants more info let me know.
