• JMS message received at only one server

  - by BJH

  I'm having a problem with a JEE6 application running in a clustered environment using WebSphere ApplicationServer 8. A search index is used for quick search in the UI (using Lucene), which must be re-indexed after new data arrived in the corresponding DB layer. To achieve this we're sending a JMS message to the application, then the search index will be refreshed. The problem is, that the messages only arrives at one of the cluster members. So only there the search index is up to date. At the other servers it remains outdated. How can I achieve that the search index gets updated at all cluster members? Can I receive the message somehow on all servers? Or is there a better way to do this?

• Getting service unavailable message when sending messages to google xmpp using wokkel

  - by Code freak

  Hi, I made a wokkel (twisted python) bot to send and receive messages from the google xmpp service. Everything (auth, presence) etc works fine. One of the rquirements of our prject is that we need to send broadcast messages to everyone in the list. Normal messages and replies work fin, but when i snd a broadcast message, i get this service unavailable error 503 message. There are about 1000 user in my contact list. Is this some bug in the code or is it google policy to prevent rapid messaging. Also, how do other google bots cater to a large contact base ? does google provide a commercial solution for such applications ? Thanks

  - by George2

  Hello everyone, I am using SQL Server 2008 Enterprise. When we met with such error message from stored procedure, Message 1205, Level 13, State 52, the process Pr_FooV2, Line 9 Services (Process ID 111) and another process is deadlock in the lock | communication buffer resources, and has been chosen as the deadlock victim.

• Broadcast message or file to nearby Bluetooth devices

  - by Medjeti

  Hiya, A client of ours is attending a business fair and would like to push some sort of "welcome message" to people visiting their space. I'm not too familiar with Bluetooth, so I have a few questions: What kind of content can you transfer via Bluetooth? (Is it files only or is it possible to send a simple text message?) Is it possible to push content only to recipients within a certain distance? (ie. based on signal strength or similar) Can anybody recommend a piece of software that can do some or all of the above? If necessary we could program a custom solution ourselves (.NET), but I'm sure there must be a program out there that can do the job. I've googled a bit and came across the 32feet.NET framework - does anybody have any experience with this framework? Thanks in advance for any suggestions!

• C++ runtime, display exception message

  - by aaa

  hello. I am using gcc on linux to compile C++ code. There are some exceptions which should not be handled and should close program. However, I would like to be able to display exception string: For example: throw std::runtime_error(" message"); does not display message, only type of error. I would like to display messages as well. Is there way to do it? it is a library, I really do not want to put catch statements and let library user decide. However, right now library user is fortran, which does not allow to handle exceptions. in principle, I can put handlers in wrapper code, but rather not to if there is a way around Thanks

• Use AJAX to check for a new message

  - by Luke

  Quite simply, I need to alert the end user when they have a new private message. From a combination of research and other opinion, I realise I need to use AJAX for this. The mysql query would be SELECT id FROM tbl_messages WHERE to_viewed = 1 So when someone sends a message, I want an alert to popup on the screen to inform the user without a page reload. I have absolutely no idea what I am doing, but know what I want. Really need help with this, AJAX is definitely something I want to improve as it opens up greater possibilities! Thanks

• Rails: How to preload a message to user

  - by Michael

  I have a Rails based prelaunch site that has some rotating background images (which are important for selling the idea of the site) that are taking too long to load, such that the users are leaving the site before they load. The only thing they're seeing is the email submission box. What's a good way to show a message to the users that the site will take some time to load but then have that message disappear after a reasonable period of time. I'm guessing a jQuery fadeOut() with a timer, but I'm not sure how long to set the timer for, because I'm not sure at what time it would start counting. Any suggestions?

• Is it viable to become a contract programmer straight out of college?

  - by M G

  I have a Bachelor of Science in Computer Science and four months research experience designing and implementing a research project. I realize this is highly dependent on my skill set - which includes C, C++, Java, Python, and SQL. I feel I have an advantage in two ways: I am young and am not afraid to work overtime. I am willing to take lower pay to gather a client base/experience, and work nights/weekends to get a few projects under my belt. This may be cliche, but I feel that I can learn new technologies quicker than most. At the very least, I am not a slow study. With this being said, is it viable for me to become a contract programmer? Or do I need the 10+ year skill set that most contractors bring to the table?

• How should I license code written for a startup without a contract?

  - by andijcr

  I wrote a fair amount of code for a startup, but I haven't signed a contract before doing so. The only document that I signed with them does not mention the fact that I have to pass the rights on the code to them, and after a consulting with a lawyer it seems that I own the full rights. Now I want to preemptively correct this situation by giving them some sort of exclusive license. Is there an existing license for closed-source, exclusive use that is used in these cases or I simply write somewhere "I grant exclusive license to use and modify this piece of code to FooBar-inc at the followings conditions: bla bla bla signed me, them"?

• Error with TextMate 2 --shell-escape and gnuplot 10.8.2

  - by Manuel

  I have had TM 1.X since a long time ago, but a week ago I updated my system to Mountain Lion 10.8.2 and installed TM2. The problem is that I write with LaTeX, and sometimes I use gnuplot for the graphs (I installed gnuplot with macports). But now it doesn't work because the --shell-escape doesn't work, this is the error message I get: Package pgfplots Error: Sorry, the gnuplot-result file '"untitled 2.pgf-plot.table"' could not be found. Maybe you need to enable the shell-escape feature? For pdflatex, this is ' pdflatex -shell-escape'. You can also invoke ' gnuplot .gnuplot' manually on the respective gnuplot file.. And then, looking around I discovered that it's not just gnuplot but everything which needs --shell-escape. Question What happened? How can I get TM have the correct rights so this works? It worked right in Snow Leopard with TM 1.5.

  The Indexing Service filter daemon keeps crashing on my WinXP Pro machine, with the following error message: "Indexing Service filter daemon has encountered a problem and needs to close. We are sorry for the inconvenience." Not a big deal, I can click "Don't Send Error Report" all day. But what's going on, here? Is this a service that I need? Is the frequent crashing indicative of something worse that's happening behind the scenes? Thanks!

• how to include error messages into backup reports for SQL Server 2008 R2?

  - by avs099

  Right now I have daily (differential) and weekly (full) backups set on my SQL Server 2008 R2 as jobs for SQL Server Agent with email notifications if job fails. I do get emails like this: JOB RUN: 'Daily backup.Diff backup' was run on 4/11/2012 at 3:00:00 AM DURATION: 0 hours, 0 minutes, 28 seconds STATUS: Failed MESSAGES: The job failed. The Job was invoked by Schedule 9 (Daily backup.Diff backup). The last step to run was step 1 (Diff backup). but often that happens because we delete/create new databases - and diff backup fails. And the only way for me to see the actual reason is to go to Log Viewer - Maintenance Plans logs. Is it possible to include "Error Message" field from the logs into notification emails? And more generic - is it possible to change notification email templates somehow?.. Thanks you.

• How to get users to read error messages?

  - by FX

  If you program for a nontechnical audience, you find yourself at a high risk that users will not read your carefully worded and enlightening error messages, but just click on the first button available with a shrug of frustration. So, I'm wondering what good practices you can recommend to help users actually read your error message, instead of simply waiving it aside. Ideas I can think of would fall along the lines of: Formatting of course help; maybe a simple, short message, with a "learn more" button that leads to the longer, more detailed error message Have all error messages link to some section of the user guide (somewhat difficult to achieve) Just don't issue error messages, simply refuse to perform the task (a somewhat "Apple" way of handling user input) Edit: the audience I have in mind is a rather broad user base that doesn't use the software too often and is not captive (i.e., not an in-house software or narrow community). A more generic form of this question was asked on slashdot, so you may want to check there for some of the answers.

• ZooKeeper and RabbitMQ/Qpid together - overkill or a good combination?

  - by Chris Sears

  Greetings, I'm evaluating some components for a multi-data center distributed system. We're going to be using message queues (via either RabbitMQ or Qpid) so agents can make asynchronous requests to other agents without worrying about addressing, routing, load balancing or retransmission. In many cases, the agents will be interacting with components that were not designed for highly concurrent access, so locking and cross-agent coordination will be needed to avoid race conditions. Also, we'd like the system to automatically respond to agent or data center failures. With the above use cases in mind, ZooKeeper seemed like it might be a good fit. But I'm wondering if trying to use both ZK and message queuing is overkill. It seems like what Zookeeper does could be accomplished by my own cluster manager using AMQP messaging, but that would be hard to get really right. On the other hand, I've seen some examples where ZooKeeper was used to implement message queuing, but I think RabbitMQ/Qpid are a more natural fit for that. Has anyone out there used a combination like this? Thanks in advance, -Chris

• Git to svn: Adding commit date to log messages

  - by Arnauld VM

  How should I do to have the author (or committer) name/date added to the log message when "dcommitting" to svn? For example, if the log message in Git is: This is a nice modif I'd like to have the message in svn be something like: This is a nice modif ----- Author: John Doo <[email protected] 2010-06-10 12:38:22 Committer: Nice Guy <[email protected] 2010-06-10 14:05:42 (Note that I'm mainly interested in the date, since I already mapped svn users in .svn-authors) Any simple way? Hook needed? Other suggestion? (See also: http://article.gmane.org/gmane.comp.version-control.git/148861) Thank you in advance. Yours faithfully, -- Arnauld Van Muysewinkel

• Whats the best method for queuing time-sensitive messages with PHP/MySQL?

  - by Mike Diena

  I'm building an SMS call and response system in a new app that receives a message via an aggregator gateway, checks it for functional keywords (run, stop, ask, etc), then processes it appropriately (save to the database, return an answer, or execute a task based on the users authorization). It's running fine at the moment as there are only a few users, but I figure its going to have more issues as we scale it up. We're currently running it on a single DV machine (mediatemple base dv). My question is this: does it make more sense to set something up like Memcached to run a queue, or a simple database with a daemon running to process each message one by one? I don't have much experience with either, so any advice would be helpful. Since the messaging is somewhat time-sensitive, what would be the fastest and most reliable way to handle this? Also, since we're sending responses, I'll probably need to set up and outbound message queue as well. Would it make sense to use the same concept for both?

• Just an experiment changing the application data path

  - by Arthur

  When I change the Appication Data path in windows xp registry to a network folder I get this error message on the next system startup: "windows cannot load the user's profile but has logged you with the default profile system" The registry keys are: "[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders]" "[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders]" under the names "AppData" and "Local AppData" I dont care if "Windows logins you with the default profile system" but is there a way to disable that message, or change the message timeout form 30 seconds to 0?,or maybe create an script that changes the Application Data path every system startup? P.S. The computer with the shared folder is always on.

• Calling finish() After Starting a New Activity

  - by stormin986

  The first Activity that loads in my application is an initialization activity, and once complete it loads a new Activity. I want to ensure if the user presses 'Back' they go straight to the Launcher, and not the initialization screen. Side note, is this even the best approach, or would this be better done with some kind of Intent Flag? Is it correct to call finish() after calling startActivity() on the new activity? onCreate() { ... startActivity(new Intent(this, NextActivity.class)); finish(); ... } I'm still taking in the whole 'Message Queue' method of doing things in Android, and my assumption is that calling startActivity() and then finish() from my first Activity's onCreate() will log each respective message in the message queue, but finish execution of onCreate() before moving on to starting the next Activity and finishing my first one. Is this a correct understanding?
