  • git: Switch branch and ignore any changes without committing.

    - by boyfarrell
    Hello, I have got the git branch I'm working on to a nice place. So I make a commit with a useful commit message. I then absentmindedly make minor changes to the code that are not work keeping. I now want to changes branches, but git gives me, error: You have local changes to "X"; cannot switch branches. I thought that I could change branches without committing? If so how can I set this up. If not, how do I get out of this problem? I want to ignore the minor changes without committing and just changes branches! Cheers, Dan

  • Android: Communication with host computer

    - by dannyn382
    I am looking for ideas as to how all of you can think to solve this issue. I am going to be using an Android Tablet as basically a touch screen input for a project. I need to be able to control servos and solenoids and such, so I will be using a Raspberry Pi to do this. I am looking for ideas on how to get the tablet and the Raspberry Pi to talk. Here are a few that I have though of so far. Use Wifi (which I really do not want to, Ethernet would be okay) to ssh into the Raspberry Pi (with an external library) and run scripts that way from the Android app. Use a com port for Android (maybe Andropod if there hardware becomes available?) and run scripts on the Raspberry Pi. Those are probably two of the "best" ideas that I can think of for now. Can anyone think of any other "better" ideas? Thanks in advance for the help, Dan

  • Design cache mechanism

    - by Delashmate
    Hi All, I got assignment to write design for cache mechanism, This is my first time writing a design document, Our program display images for doctors, and we wan't to reduce the parsing time of the images So we want to save the parsed data in advance (in files or inside database) Currently I have several design key ideas Handle locks - each shared data structure should be handled, also files Test - add test to verify the data from the cache is equal to the data from the files To decouple the connection to the database- not to call directly to the database Cleanup mechanisem- to delete old files if the cahce directory exceed configurable threshold Support config file Support performance tool in the feature I will also add class diagram, data flow charts, and workflow What do you think I should add to the key ideas? Do you know good link to atricales about design? Thanks in advance, Dan

  • Informal Interviews: Just Relax (or Should I?)

    - by david.talamelli
    I was in our St Kilda Rd office last week and had the chance to meet up with Dan and David from GradConnection. I love what these guys are doing, their business has been around for two years and I really like how they have taken their own experiences from University found a niche in their market and have chased it. These guys are always networking. Whenever they come to Melbourne they send me a tweet to catch up, even though we often miss each other they are persistent. It sounds like their business is going from strength to strength and I have to think that success comes from their hard work and enthusiasm for their business. Anyway, before my meeting with ProGrad I noticed a tweet from Kevin Wheeler who was saying it was his last day in Melbourne - I sent him a message and we met up that afternoon for a coffee (I am getting to the point I promise). On my way back to the office after my meeting I was on a tram and was sitting beside a lady who was talking to her friend on her mobile. She had just come back from an interview and was telling her friend how laid back the meeting was and how she wasn't too sure of the next steps of the process as it was a really informal meeting. The recurring theme from this phone call was that 1) her and the interviewer got along really well and had a lot in common 2) the meeting was very informal and relaxed. I wasn't at the interview so I cannot say for certain, but in my experience regardless of the type of interview that is happening whether it is a relaxed interview at a coffee shop or a behavioural interview in an office setting one thing is consistent: the employer is assessing your ability to perform the role and fit into the company. Different interviewers I find have different interviewing styles. For example some interviewers may create a very relaxed environment in the thinking this will draw out less practiced answers and give a more realistic view of the person and their abilities while other interviewers may put the candidate "under the pump" to see how they react in a stressful situation. There are as many interviewing styles as there are interviewers. I think candidates regardless of the type of interview need to be professional and honest in both their skills/experiences, abilities and career plans (if you know what they are). Even though an interview may be informal, you shouldn't slip into complacency. You should not forget the end goal of the interview which is to get a job. Business happens outside of the office walls and while you may meet someone for a coffee it is still a business meeting no matter how relaxed the setting. You don't need to be stick in the mud and not let your personality shine through, but that first impression you make may play a big part in how far in the interview process you go.

  • The .NET Rocks! Visual Studio 2010 Road Trip

    - by Laila
    Carl Franklin and Richard Campbell, the two .NET Rocks radio show hosts, have decided to set off to 15 cities in the US, between April 19th and May 7th, in their DotNetMobile (a 30 foot RV). What for you'll ask me? Well, to drive around the US, meet up with .NET developers, and show off the latest and greatest in Visual Studio 2010 and .NET 4.0! Each evening, they stop in a city and host a three hour event in front of a 100 to 300 crowd of developers, where Carl is showing off media features in Silverlight 4 and their road trip tracking application, whilst Richard is demo-ing the web performance testing features of VS2010 using his portable server rig. But before they take to the stage, they have a special guest brought in - a rock star from the Visual Studio world - whom they interview for an hour as a .NET Rock episode. So far, they've had - amongst others - Phil Haack, a Program Manager with the ASP.NET team working on ASP.NET MVC, Dan Fernandez, an Evangelism Manager in the Developer and Platform Evangelism team at Microsoft, and Beth Massi, Senior Program Manager on the Visual Studio Community Team at Microsoft. I love the fact that the audience gets a chance to participate, ask questions and have a great laugh, as you can hear in the first episode! Along the way, the .NET Rocks guys are giving away great prizes (including .NET Reflector Pro, ANTS Memory Profiler licenses, and "40" LCD TVs!). Even more out of the ordinary, at each stop on the road trip, one lucky attendee (who entered in the Ride Along competition) gets to jump in the RV with Carl and Richard and ride along with them to the next stop on the roadtrip. How cool is that! Richard told us: "Our first winner in Mountain View was Eric Ziko. I was looking for him to announce that he had won, when he found us and gave us a bottle of scotch he had brought just to say 'thanks for the great show'. We all had a toast from the bottle the next night when he headed back home." Cheeky! There's still space to a few of these events, so if you want to attend, register now, because it's first come first serve. We're grateful to Richard and Carl for giving us the opportunity to sponsor this major .NET event! A unique .NET adventure worth following for sure. Cheers, Laila

  • BI Publisher - Hottest Show in Vegas

    - by mike.donohue
    Two days down, two to go. Monday was a very busy and rewarding day. Attended "XML Publisher and FSG for Beginners" given by Susan Behn and Alyssa Johnson from Solution Beacon. It was packed, standing room only ... even though it was at 8:00 am. Later in the afternoon, despite being at the same time and in conflict with other Publisher related sessions, Noelle's session, "The Reporting Platform for Applications: Oracle Business Intelligence Publisher" and my session, "Introduction to Oracle Business Intelligence Publisher" were both very well attended. Immediately following our presentations we ran the BI Publisher Hands On Lab which was great fun. The turnout was so large that unfortunately we could not accommodate everyone who came to the lab. There were as many as 5 people huddled around each of the 20 machines. All the the groups completed the 2 main exercises. Some groups even took the product for an off-road test drive. Look at all the fun we had ... For those who could not attend or want the Hands On Lab document: Hands On Lab Oracle BI Publisher Collaborate 2010.pdf Note that these lab instructions assume a specific set up and files that you may not have in your environment. You can download and install a trial license version of BI Publisher from the download page. Highly recommend taking a look at the additional Tutorials available on OTN. Big thanks to Dan Vlamis and Jonathan Clark from Vlamis Software Solutions and to the Oracle BIWA SIG for setting up these machines and getting the time and space to run this lab. It was inspiring to see all of the attendees successfully creating reports. On Tuesday morning we were up early again for a rousing session of BI Publisher Best Practices that was also, very well attended especially considering the 8 am start. Later that morning saw Ben Bruno from STR Software and two of his customers speak on the additional functionality and ROI they have achieved by using Publisher within EBS and AventX to FAX and Email Publisher generated documents. Spent the afternoon staffing the BI Technology demo pod and had a steady flow of people dropping by with questions. Having a great conference so far and looking forward to the rest of it.

  • AIIM, Oracle and Keste - Talking Social Business in LA

    - by Brian Dirking
    We had a great event today in Los Angeles - AIIM, Oracle and Keste presented on how organizations are making social business work. Atle Skjekkeland of AIIM presented How Social Business Is Driving Innovation. Atle talked about a number of fascinating points, such as how answers to questions come from unexpected sources. Atle cited the fact that 38% of organizations get half or more of answers from unexpected sources, which speaks to the wisdom of the crowds and how people are benefiting from open communications tools to get answers to their questions. He also had a number of hilarious examples of companies that don't get it. If Comcast were to go to YouTube and search Comcast, they would see the number one hit after their paid ad is a video of one of their technicians asleep on a customer's couch. Seems when he called the office for support he was put on hold so long he fell asleep. Dan O'Leary and Atle Skjekkeland After Atle's presentation I presented on Solving the Innovation Challenge with Oracle WebCenter. Atle had talked about McKinsey's research titled The Rise Of The Networked Enterprise: Web 2.0 Finds Its Payday. I brought in some new McKinsey research that built on that article. The new article is How Social Technologies Are Extending The Organization. A survey of 4,200 Global Executives brought three conclusions for the future: Boundaries among employees, vendors and customers will blur Employee teams will self-organize Data-driven decisions will rise These three items were themes that repeated through the day as we went through examples of what customers are doing today.  Next up was Vince Casarez of Keste. Vince was scheduled to profile one customer, but in an incredible 3 for 1 deal, Vince profiled Alcatel-Lucent, Qualcomm, and NetApp. Each of these implementations had content consolidation elements, as well as user engagement requirements that Keste was able to address with Oracle WebCenter. Vince Casarez of Keste And we had a couple of good tweets worth reprinting here. danieloleary Daniel O'Leary Learning about user engagement and social platforms from @bdirking #AIIM LA and @oracle event pic.twitter.com/1aNcLEUs danieloleary Daniel O'Leary Users want to be able to share data and activity streams, work at organizations that embrace social via @bdirking skjekkeland Atle Skjekkeland RT @danieloleary: Learning about user engagement and social platforms from @bdirking #AIIM LA and @oracle event pic.twitter.com/EWRYpvJa danieloleary Daniel O'Leary Thanks again to @bdirking for an amazing event in LA today, really impressed with the completeness of web center JimLundy Jim Lundy @ @danieloleary @bdirking yes, it is looking good - Web Center shadrachwhite Shadrach White @ @bdirking @heybenito I heard the #AIIM event in LA was a hit We had some great conversations through they day, many thanks to everyone who joined in.

  • Oracle Open World 2012 is Here!

    - by thatjeffsmith
    Just a quick post today and then probably not much more until next week. Speaking, running hands on labs, meets and greets, and trying to keep up with folks like @oraclenerd means I won’t have much time to write until I get home from San Francisco. Wanted to give a quick shout out to my co-worker and partner-in-Product Management-crime, Ashley Chen this morning. She signed me up for a run across the Golden Gate and back with @bamcgill a few months ago…mostly with my permission. The only thing was, I didn’t run at the time, and that’s basically a 5k. But having goals is good. And yesterday I met a big goal of mine – not looking stupid trying to run across the Golden Gate Bridge. Ok, I did the run and mabye looked a little bit stupid. Ashley, Barry, and I Pre-Run Perfect weather and no fog to cloud the view! So the pre-show fun is over and now it’s time for the show fun to begin. At Oracle Open World? Come by our demo pods. We’re with the other Database folks in the back right-hand corner. We’ll have folks on hand to talk and show Oracle SQL Developer, Oracle SQL Developer Data Modeler, Migrations, and Oracle APEX Listener. Oracle SQL Developer Demo Pod I have the full schedule of SQL Developer presentations and hands on labs here. I know there’s a lot of news on tap this week in the world of Oracle, and we’ll start talking more about it soon. So be sure to subscribe to my feed if you don’t want to miss any of my posts. And I promise not to post any more pictures me. Speaking of pictures, thanks to @dmcghan – or as I call him, ‘Dan the Man’ for running with us and being our official portrait photographer! If you don’t follow him, he’s a great fountain of knowledge in the Oracle APEX world and is one of our ACEs.

Live, Thursday Nov 8, 10am PT/ 1pm ET. Solving Big Problems in Our 21st Century Information Society | Irving Wladawsky-Berger "I believe that the kind of extensive collaboration between the private sector, academia and government represented by the Internet revolution will be the way we will generally tackle big problems in the 21st century. Just as with the Internet, governments have a major role to play as the catalyst for many of the big projects that the private sector will then take forward and exploit. The need for high bandwidth, robust national broadband infrastructures is but one such example." — Irving Wladawsky-Berger SOA Still Not Dead: Ratification of Governance Standard Highlights SOA’s Continued Relevance So just about the time I dig into Google Trends to learn that the conversation about governance peaked in 2004, along comes all this InfoQ article by Richard Seroter. And of course you've already listened to the OTN Archbeat Podcast about governance, right? Right? Implications of Java 6 End of Public Updates for Oracle E-Business Suite Users | Steven Chan The short version is: "Nothing will change for EBS users after February 2013." According to Steven Chan, "EBS users will continue to receive critical bug fixes and security fixes as well as general maintenance for Java SE 6." You'll find additional information on Steven's blog. ADF Mobile Custom Javascript – iFrame Injection | John Brunswick The ADF Mobile Framework provides a range of out of the box components to add within your AMX pages, according to John Brunswick. But what happens when "an out of the box component does not directly fulfill your development need? What options are available to extend your application interface?" John has an answer. How Data and BPM are married to get the right information to the right people at the right time | Leon Smiers "Business Process Management…supports a large group of stakeholders within an organization, all with different needs," says Oracle ACE Leon Smiers. "End-to-end processes typically run across departments, stakeholders and applications, and can often have a long life-span. So how do organizations provide all stakeholders with the information they need?" Leon provides answers in this post. Thought for the Day "(When) asking skilled architects…what they do when confronted with highly complex problems…(they) would most likely answer, 'Just use Common Sense.' (A) better expression than 'common sense' is 'contextual sense' — a knowledge of what is reasonable within a given content. Practicing architects through eduction, experience and examples accumulate a considerable body of contextual sense by the time they're entrusted with solving a system-level problem…" — Eberhardt Rechtin (January 16, 1926 – April 14, 2006) Source: SoftwareQuotes.com

  • JUDCon 2013 Trip Report

    - by reza_rahman
    JUDCon (JBoss Users and Developers Conference) 2013 was held in historic Boston on June 9-11 at the Hynes Convention Center. JUDCon is the largest get together for the JBoss community, has gone global in recent years but has it's roots in Boston. The JBoss folks graciously accepted a Java EE 7 talk from me and actually referenced my talk in their own sessions. I am proud to say this is my third time speaking at JUDCon/the Red Hat Summit over the years (this was the first time on behalf of Oracle). I had great company with many of the rock stars of the JBoss ecosystem speaking such as Lincoln Baxter, Jay Balunas, Gavin King, Mark Proctor, Andrew Lee Rubinger, Emmanuel Bernard and Pete Muir. Notably missing from JUDCon were Bill Burke, Burr Sutter, Aslak Knutsen and Dan Allen. Topics included Java EE, Forge, Arquillian, AeroGear, OpenShift, WildFly, Errai/GWT, NoSQL, Drools, jBPM, OpenJDK, Apache Camel and JBoss Tools/Eclipse. My session titled "JavaEE.Next(): Java EE 7, 8, and Beyond" went very well and it was a full house. This is our main talk covering the changes in JMS 2, the Java API for WebSocket (JSR 356), the Java API for JSON Processing (JSON-P), JAX-RS 2, JPA 2.1, JTA 1.2, JSF 2.2, Java Batch, Bean Validation 1.1, Java EE Concurrency and the rest of the APIs in Java EE 7. I also briefly talked about the possibilities for Java EE 8. The slides for the talk are here: JavaEE.Next(): Java EE 7, 8, and Beyond from reza_rahman Besides presenting my talk, it was great to catch up with the JBoss gang and attend a few interesting sessions. On Sunday night I went to one of my favorite hangouts in Boston - the exalted Middle East Club as Rolling Stone refers to it (other cool spots in an otherwise pretty boring town is "the Church"). As contradictory as it might sound to the uninitiated, the Middle East Club is possibly the best place in Boston to simultaneously get great Middle Eastern (primarily Lebanese) food and great underground metal. For folks with a bit more exposure, this is probably not contradictory at all given bands like Acrassicauda and documentaries like Heavy Metal in Baghdad. Luckily for me they were featuring a few local Thrash metal bands from the greater Boston area. It wasn't too bad considering it was primarily amateur twenty-something guys (although I'm not sure I'm a qualified critic any more since I all but stopped playing about at that age). It's great Boston has the Middle East as an incubator to keep the rock, metal, folk, jazz, blues and indie scene alive. I definitely enjoyed JUDCon/Boston and hope to be part of the conference next year again.

  • It is CX a new concept?

    - by Isabel F. Peñuelas
    The Marketing Industry and the Web Industry are talking about CX since some time. However it is only very recently that the concept has reached some common meaning accepted by the analysts’ and the IT community. The new CX model depends on two previous facts: the expansion of the social media, and the impact of the new advanced features of mobile devices regarding brand-customer interaction. CXsers vs UXers First there is some need of disambiguity between User Experience and Customer Experience. User Experience -UX, is a much well established concept related with the design of user interactions for particular devices. UX people are interested on multiple touch points of digital interfaces while CX people are interested on all kind of interfaces including physical ones. UX is an evolution of Web Usability, while CX is a marketing concept. UX is an instrument of User Experience. CX in fact is all about Connections and Interactions. Connections Dan Draper, the creative director Mad Men, understands very well that to market effectively means to connect with people, and the best way to connect to people is to use the connections people have with other people: understanding Social Media connections and taking the customer pulse of customers on those medias, and are strong facilitators of CX strategies.  Interactions We can very simply define CX as the relationship that a customer establishes with a brand through multiple touch points (interactions, channels) through the entire life cycle of his relationship- direct or indirect with the brand. Interactions can be grouped on Customer Journeys through multiple touch points defined as the path a customer follows to achieve a goal. Processes A customer journey today usually starts at the moment he surfs the Web, then he takes a purchase decision; purchases the product;  request a particular service and finally recommends or do not recommends the product.  Customer Journeys are processes, and to analyze customer journeys there exists today a broad offering of modern Customer Journey tools very similar actually to the use cases or UML activity diagrams for IT systems design. As a summary CX is nothing more and nothing less than applying process analysis methods for better understanding how to create value through customer interactions across the multiple user´s touch points with the brand.

  • SQL Saturday 43 (Redmond, WA) Review

    - by BuckWoody
    Last Saturday (June 12th) we held a “SQL Saturday” (more about those here) event in Redmond, Washington. The event was held at the Microsoft campus, at the Mixer in our new location called the “Commons”. This is a mall-like area that we have on campus, and the Mixer is a large building with lots of meeting rooms, so it made a perfect location for the event. There was a sign to find the parking, and once there they had a sign to show how to get to the building. Since it’s a secure facility, Greg Larsen and crew had a person manning the door so that even late arrivals could get in. We had about 400 sign up for the event, and a little over 300 attend (official numbers later). I think we would have had a lot more, but the sun was out – and you just can’t underestimate the effect of that here in the Pacific Northwest. We joke a lot about not seeing the sun much, but when a day like what we had on Saturday comes around, and on a weekend at that, you’d cancel your wedding to go outside to play in the sun. And your spouse would agree with you for doing it. We had some top-notch speakers, including Clifford Dibble and Kalen Delany. The food was great, we had multiple sponsors (including Confio who seems to be at all of these) and the attendees were from all over the professional spectrum, from developers to BI to DBA’s. Everyone I saw was very engaged, and when I visited room-to-room I saw almost no one in the halls – everyone was in the sessions. I also saw a much larger Microsoft presence this year, especially from Dan Jones’ team. I had a great turnout at my session, and yes, I was wearing an Oracle staff shirt. I did that because I wanted to show that the session I gave on “SQL Server for the Oracle DBA” was non-marketing – I couldn’t exactly bash Oracle wearing their colors! These events are amazing. I can’t emphasize enough how much I appreciate the volunteers and how much work they put into these events, and to you for coming. If you’re reading this and you haven’t attended one yet, definitely find out if there is one in your area – and if not, start one. It’s a lot of work, but it’s totally worth it.       Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

  • Oracle At QCon SF 2012

    - by Cassandra Clark - OTN
    Oracle Technology Network is a Platinum sponsor at QCon San Francisco.  (qconsf.com).  Don’t miss these great developer focused sessions: Shay ShmeltzerHow we simplified Web, Mobile and Cloud development for our own developers? - the Oracle StoryOver the past several years, Oracle has beendeveloping a new set of enterprise applications in what is probably one of thelargest Java based development project in the world. How do you take 3000 developers and make them productive? How do you insure the delivery of cutting edge UIs for both Mobile and Web channels? How do you enable Cloud baseddevelopment and deployment?  Come and learn how we did it at Oracle, and see how the same technologies and methodologies can apply to your development efforts. Dan SmithProject Lambda in Java 8Java SE 8 will include major enhancements to the Java Programming Language and its core libraries.  This suite of new features, known as Project Lambda in the OpenJDK community, includes lambda expressions, default methods, and parallel collections (and much more!).  The result will be a next-generation Java programming experience with more flexibility and better abstractions.   This talk will introduce the new Java features and offer a behind-the-scenes view of how they evolved and why they work the way that they do. Arun GuptaJSR 356: Building HTML5 WebSocket Applications in JavaThe family of HTML5 technologies has pushed the pendulum away from rich client technologies and toward ever-more-capable Web clients running on today’s browsers. In particular, WebSocket brings new opportunities for efficient peer-to-peer communication, providing the basis for a new generation of interactive and “live” Web applications. This session examines the efforts under way to support WebSocket in the Java programming model, from its base-level integration in the Java Servlet and Java EE containers to a new, easy-to-use API and toolset that are destined to become part of the standard Java platform. The full conference schedule is here: http://qconsf.com/sf2012/schedule/wednesday.jsp But wait, there’s more!  At the Oracle booth, we’ll also be covering: ·         Oracle ADF Mobile·         Oracle Developer Cloud Service·         Oracle ADF Essentials·         NetBeans Project Easel Lastly we’ll share the results of a short cloud survey at QConSF ater this week.  If you attended this year's Oracle OpenWorld and JavaOne conferences, it would be hard not to notice that Oracle is clearly "all-in" when it comes to the Cloud.  With Cloud computing being such a hot topic on many OTN members' minds, we'd like to know what you're doing in the cloud and invite you to take this short cloud survey.

  • directory with 980MB meta data, millions of files, how to delete it? (ext3)

    - by Alexandre
    Hello, So I'm stuck with this directory: drwxrwxrwx 2 dan users 980M 2010-12-22 18:38 sessions2 The directories contents is small - just millions of tiny little files. I want to wipe it from the filesystem but have been unable to. My first try was: find sessions2 -type f -delete and find sessions2 -type f -print0 | xargs -0 rm -f but had to stop because both caused escalating memory usage. At one point it was using 65% of the system's memory. So I thought (no doubt incorrectly), that it had to do with the fact that dir_index was enabled on the system. Perhaps find was trying to read the entire index into memory? So I did this (foolishly): tune2fs -O^dir_index /dev/xxx Alright, so that should do it. Ran the find command above again and... same thing. Crazy memory usage. I hurriedly ran tune2fs -Odir_index /dev/xxx to reenable dir_index, and ran to Server Fault! 2 questions: 1) How do I get rid of this directory on my live system? I don't care how long it takes, as long as it uses little memory and little CPU. By the way, using nice find ... I was able to reduce CPU usage, so my problem right now is only memory usage. 2) I disabled dir_index for about 20 minutes. No doubt new files were written to the filesystem in the meanwhile. I reenabled dir_index. Does that mean the system will not find the files that were written before dir_index was reenabled since their filenames will be missing from the old indexes? If so and I know these new files aren't important, can I maintain the old indexes? If not, how do I rebuild the indexes? Can it be done on a live system? Thanks!

  • Is my dns server being attacked? And what should I do about it?

    - by Mnebuerquo
    I've been having some intermittent dns problems with a web server, where certain isp's dns servers don't have my hostnames in cache and fail to look them up. At the same time, queries to opendns for those hostnames resolve correctly. It's intermittent, and it always works fine for me, so it's hard to identify the problem when someone reports connectivity problems to my site. In trying to figure this out, I've been looking at my logs to see if there are any errors I should know about. I found thousands of the following messages in my logs, from different ip's, but all requesting similar dns records: May 12 11:42:13 localhost named[26399]: client 94.76.107.2#36141: query (cache) 'burningpianos.com/MX/IN' denied May 12 11:42:13 localhost named[26399]: client 94.76.107.2#29075: query (cache) 'burningpianos.com/MX/IN' denied May 12 11:42:13 localhost named[26399]: client 94.76.107.2#47924: query (cache) 'burningpianos.com/MX/IN' denied May 12 11:42:13 localhost named[26399]: client 94.76.107.2#4727: query (cache) 'burningpianos.com/MX/IN' denied May 12 11:42:14 localhost named[26399]: client 94.76.107.2#16153: query (cache) 'burningpianos.com/MX/IN' denied May 12 11:42:14 localhost named[26399]: client 94.76.107.2#40267: query (cache) 'burningpianos.com/MX/IN' denied May 12 11:43:35 localhost named[26399]: client 82.209.240.241#63507: query (cache) 'burningpianos.com/MX/IN' denied May 12 11:43:35 localhost named[26399]: client 82.209.240.241#63721: query (cache) 'burningpianos.org/MX/IN' denied May 12 11:43:36 localhost named[26399]: client 82.209.240.241#3537: query (cache) 'burningpianos.com/MX/IN' denied I've read of Dan Kaminski's dns cache poisoning vulnerability, and I'm wondering if these log records are an attempt by some evildoer to attack my dns server. There are thousands of records in my logs, all requesting "burningpianos", some for com and some for org, most looking for an mx record. There are requests from multiple ip's, but each ip will request hundreds of times per day. So this smells to me like an attack. What is the defense against this?

  • Keep-Alive header not sent from Tomcat 5.5 http connector?

    - by Codek
    We're currently using a hardware load balancer, which then goes to Apache and that then goes to Tomcat 5.5 via the AJP connector. We've decided to dump apache for various reasons - In our current system it doesnt provide any advantage. However when I look at the headers sent when we do this, the "Keep-Alive: timeout=15 max=96" header doesnt get sent when you use the tomcat http connector Interestingly, i can find no documentiation on "keepalivetimeout" for tomcat5.5, but i can for tomcat6. But neither can i find evidence that tomcat5.5 doesnt support this setting. here's my connector: <Connector port="8090" maxHttpHeaderSize="8192" maxThreads="400" minSpareThreads="150" maxSpareThreads="300" enableLookups="false" connectionTimeout="2" maxKeepAliveRequests="400" disableUploadTimeout="true" /> So; Is there any way I can specify the keepalive timeout if we use the http connector with tomcat 5.5, and force this header entry to be sent? Just to be clear - the exact header entry i see back from the server is this with apache: Keep-Alive: timeout=2, max=100 But nothing from tomcat/coyote. I've looked at this some more, and I dont think the Keep-Alive header entry really matters. The problem seems to be that keep-alives are simply not supported in tomcat 5.5 http connector? They do seem to work in tomcat6 (+java 6). Thanks, Dan
