  • ASP.NET Session Management

    - by geekrutherford
    Great article (a little old but still relevant) about the inner workings of session management in ASP.NET: Underpinnings of the Session State Management Implementation in ASP.NET.   Using StateServer and the BinaryFormatter serialization occuring caused me quite the headache over the last few days. Curiously, it appears the w3wp.exe process actually consumes more memory when utilizing StateServer and storing somewhat large and complex data types in session.   Users began experiencing Out Of Memory exceptions in the production environment. Looking at the stack trace it related to serialization using the BinaryFormatter. Using remote debugging against our QA server I noted that the code in the application functioned without issue. The exception occured outside the context of the application itself when the request had completed and the web server was trying to serialize session state into the StateServer.   The short term solution is switching back to the InProc method. Thus far this has proven to consume considerably less memory and has caused no issues. Long term the complex object stored in session will be off-loaded into a web service used to access the information directly from the database outside the context of the object used to encapsulate it.

  • How do you manage a complexity jump?

    - by glenatron
    It seems an infrequent but common experience that sometimes you're working on a project and suddenly something turns up unexpectedly, throws a massive spanner in the works and ramps up the complexity a whole lot. For example, I was working on an application that talked to SOAP services on various other machines. I whipped up a prototype that worked fine, then went on to develop a regular front end and generally get everything up and running in a nice, fairly simple and easy to follow fashion. It worked great until we started testing across a wider network and suddenly pages started timing out as the latency of the connections and the time required to perform calculations on remote machines resulted in timed out requests to the soap services. It turned out that we needed to change the architecture to spin requests out onto their own threads and cache the returned data so it could be updated progressively in the background rather than performing calculations on a request by request basis. The details of that scenario are not too important - indeed it's not a great example as it was quite forseeable and people who have written a lot of apps of this type for this type of environment might have anticipated it - except that it illustrates a way that one can start with a simple premise and model and suddenly have an escalation of complexity well into the development of the project. What strategies do you have for dealing with these types of functional changes whose need arises - often as a result of environmental factors rather than specification change - later on in the development process or as a result of testing? How do you balance between avoiding the premature optimisation/ YAGNI/ overengineering risks of designing a solution that mitigates against possible but not necessarily probable issues as opposed to developing a simpler and easier solution that is likely to be as effective but doesn't incorporate preparedness for every possible eventuality?

  • Oracle Java Olympics Between Russia, Ukraine, Belarus, Ukraine and Kazakhstan

    - by Tori Wieldt
    Last month, 151 universities in 11 locations (Saint-Petersburg, Moscow, Donetsk, Tomsk, Odessa, Rostov-on-Don, Ekaterinburg, Khabarovsk, Almaty, Kiev, and Samara) competed in the second round of the Oracle Java Olympics. For two weeks in February, the best university students from Russia, Ukraine, Belarus, Ukraine and Kazakhstan were invited to compete with each other and prove just how good they are in Java programming.  A team of engineers from Oracle Development center in Saint-Petersburg prepared the set of problems to solve during the competition. To win, participants needed to show deep knowledge of Java technologies from Classloader and NIO to Reflection and JavaDB. Students in each location had a PC with Oracle JDK 1.7u2 and Netbeans 7.1.  As a testing system, the organizers used the open source software Ejudge (with several tweaks specifically for the competition).  Participants submitted their solutions to the remote server where they were tested by prepared test harnesses. All results were posted in real-time. "I followed the competition coming in from the many sites, and it was a really exciting experience, like a horse race or football game!" exclaimed Java Evangelist Alexander Belokrylov. Congratulations to everyone who competed! The Olympic finals will on April 4th.

  • Architectural and Design Challenges with SOA

    With all of the hype about service oriented architecture (SOA) primarily through the use of web services, not much has been said about potential issues of using SOA in the design of an application. I am personally a fan of SOA, but it is not the solution for every application. Proper evaluation should be done on all requirements and use cases prior to deciding to go down the SOA road. It is important to consider how your application/service will handle the following perils as it executes. Example Challenges of SOA Network Connectivity Issues Handling Connectivity Issues Longer Processing/Transaction Times How many of us have had issues visiting our favorite web sites from time to time? The same issue will occur when using service based architecture especially if it is implemented using web services. Forcing applications to access services via a network connection introduces a lot of new failure points to the application. Potential failure points include: DNS issues, network hardware issues, remote server issues, and the lack of physical network connections. When network connectivity issues do occur, how are the service clients are implemented is very important. Should the client wait and poll the service until it is accessible again? If so what is the maximum wait time or number of attempts it should retry. Due to the fact of services being distributed across a network automatically increase the responsiveness of client applications due to the fact that processing time must now also include time to send and receive messages from called services. This could add nanoseconds to minutes per each request based on network load and server usage of the service provider. If speed highly desirable quality attribute then I would consider creating components that are hosted where the client application is located. References: Rader, Dave. (2002).

  • Purpose oriented user accounts on a single desktop?

    - by dd_dent
    Starting point: I currently do development for Dynamics Ax, Android and an occasional dabble with Wordpress and Python. Soon, I'll start a project involving setting up WP on Google Apps Engine. Everything is, and should continue to, run from the same PC (running Linux Mint). Issue: I'm afraid of botching/bogging down my setup due to tinkering/installing multiple runtimes/IDE's/SDK's/Services, so I was thinking of using multiple users, each purposed to handle the task at hand (web, Android etc) and making each user as inert as possible to one another. What I need to know is the following: Is this a good/feasible practice? The second closest thing to this using remote desktops connections, either to computers or to VM's, which I'd rather avoid. What about switching users? Can it be made seamless? Anything else I should know? Update and clarification regarding VM's and whatnot: The reason I wish to avoid resorting to VM's is that I dislike the performance impact and sluggishness associated with it. I also suspect it might add a layer of complexity I wish to avoid. This answer by Wyatt is interesting but I think it's only partly suited for requirements (web development for example). Also, in reference to the point made about system wide installs, there is a level compromise I should accept as experessed by this for example. This option suggested by 9000 is also enticing (more than VM's actually) and by no means do I intend to "Juggle" JVMs and whatnot, partly due to the reason mentioned before. Regarding complexity, I agree and would consider what was said, only from my experience I tend to pollute my work environment with SDKs and runtimes I tried and discarded, which would occasionally leave leftovers which cause issues throught the session. What I really want is a set of well defined, non virtualized sessions from which I can choose at my leisure and be mostly (to a reasonable extent) safe from affecting each session from the other. And what I'm really asking is if and how can this be done using user accounts.

  • Skynet Big Data Demo Using Hexbug Spider Robot, Raspberry Pi, and Java SE Embedded (Part 3)

    - by hinkmond
    In Part 2, I described what connections you need to make for this demo using a Hexbug Spider Robot, a Raspberry Pi, and Java SE Embedded for programming. Here are some photos of me doing the soldering. Software engineers should not be afraid of a little soldering work. It's all good. See: Skynet Big Data Demo (Part 2) One thing to watch out for when you open the remote is that there may be some glue covering the contact points. Make sure to use an Exacto knife or small screwdriver to scrape away any glue or non-conductive material covering each place where you need to solder. And after you are done with your soldering and you gave the solder enough time to cool, make sure all your connections are marked so that you know which wire goes where. Give each wire a very light tug to make sure it is soldered correctly and is making good contact. There are lots of videos on the Web to help you if this is your first time soldering. Check out Laday Ada's (from adafruit.com) links on how to solder if you need some additional help: http://www.ladyada.net/learn/soldering/thm.html If everything looks good, zip everything back up and meet back here for how to connect these wires to your Raspberry Pi. That will be it for the hardware part of this project. See, that wasn't so bad. Hinkmond

  • Spotlight on GlassFish 4.1: #7 WebSocket Session Throttling and JMX Monitoring

    - by delabassee
    'Spotlight on GlassFish 4.1' is a series of posts that highlights specific enhancements of the upcoming GlassFish 4.1 release. It could be a new feature, a fix, a behavior change, a tip, etc. #7 WebSocket Session Throttling and JMX Monitoring GlassFish 4.1 embeds Tyrus 1.8.1 which is compliant with the Maintenance Release of JSR 356 ("WebSocket API 1.1"). This release also brings brings additional features to the WebSocket support in GlassFish. JMX Monitoring: Tyrus now exposes WebSocket metrics through JMX . In GF 4.1, the following message statistics are monitored for both sent and received messages: messages count messages count per second average message size smallest message size largest message size Those statistics are collected independently of the message type (global count) and per specific message type (text, binary and control message). In GF 4.1, Tyrus also monitors, and exposes through JMX, errors at the application and endpoint level. For more information, please check Tyrus JMX Monitoring Session Throttling To preserve resources on the server hosting websocket endpoints, Tyrus now offers ways to limit the number of open sessions. Those limits can be configured at different level: per whole application per endpoint per remote endpoint address (client IP address)   For more details, check Tyrus Session Throttling. The next entry will focus on Tyrus new clients-side features.

  • How to apply verification and validation on the following example

    - by user970696
    I have been following verification and validation questions here with my colleagues, yet we are unable to see the slight differences, probably caused by language barrier in technical English. An example: Requirement specification User wants to control the lights in 4 rooms by remote command sent from the UI for each room separately. Functional specification The UI will contain 4 checkboxes labelled according to rooms they control. When a checkbox is checked, the signal is sent to corresponding light. A green dot appears next to the checkbox When a checkbox is unchecked, the signal (turn off) is sent to corresponding light. A red dot appears next to the checkbox. Let me start with what I learned here: Verification, according to many great answers here, ensures that product reflects specified requirements - as functional spec is done by a producer based on requirements from customer, this one will be verified for completeness, correctness). Then design document will be checked against functional spec (it should design 4 checkboxes..), and the source code against design (is there a code for 4 checkboxes, functions to send the signals etc. - is it traceable to requirements). Okay, product is built and we need to test it, validate. Here comes our understanding trouble - validation should ensure the product meets requirements for its specific intended use which is basically business requirement (does it work? can I control the lights from the UI?) but testers will definitely work with the functional spec, making sure the checkboxes are there, working, labelled, etc. They are basically checking whether the requirements in functional spec were met in the final product, isn't that verification? (should not be, lets stick to ISO 12207 that only validation is the actual testing)

  • Methodology To Determine Cause Of User Specific Error

    - by user3163629
    We have software that for certain clients fails to download a file. The software is developed in Python and compiled into an Windows Executable. The cause of the error is still unknown but we have established that the client has an active internet connection. We suspect that the cause is due to the clients network setup. This error cannot be replicated in house. What technique or methodology should be applied to this kind of specific error that cannot be replicated in house. The end goal is to determine the cause of this error so we can move onto the solution. For example; Remote Debugging: Produce a debug version of the software and ask the client to send back a debug output file. This involves alot of time (back and forth communication) and requires the client to work and act in a timely manor to be successful. In-house debugging: Visit the client and determine their network setup, etc. Possibly develop a series of script tests before hand to run on the clients computer under the same network. Other methodologies and techniques I am not aware of?

  • How to minimize the usage of static variables and objects

    - by Peter Penzov
    I'm trying to implement this JavaFX code where I want to call remote Java class and pass boolean flag: final CheckMenuItem toolbarSubMenuNavigation = new CheckMenuItem("Navigation"); toolbarSubMenuNavigation.setOnAction(new EventHandler<ActionEvent>() { @Override public void handle(ActionEvent e) { //DataTabs.renderTab = toolbarSubMenuNavigation.isSelected(); DataTabs.setRenderTab(toolbarSubMenuNavigation.isSelected()); // call here the getter setter and send boolean flag System.out.println("subsystem1 #1 Enabled!"); } }); Java class which I want to call: public class DataTabs { private static boolean renderTab; // make members *private* private static TabPane tabPane; public static boolean isRenderTab() { return DataTabs.renderTab; } public static void setRenderTab(boolean renderTab) { DataTabs.renderTab = renderTab; tabPane.setVisible(renderTab); } // somewhere below // set visible the tab pane TabPane tabPane = DataTabs.tabPane = new TabPane(); tabPane.setVisible(renderTab); } This implementation works but I want to optimize it to use less static variables and objects. Can you tell me which sections of the code how can be optimized?

  • Code base migration - old versioning system to modern

    - by JohnP
    Our current code base is contained in a versioning system that is old and outdated (Visual Sourcesafe 5.0, mid 1990's), and contains a mix of packages that are no longer used, ones that are being used but no longer updated, and newer code. It is also a mix of 4 languages, and includes libraries for some of our systems (Such as Dialogic, Sun Tzu {clipper}) implementations. This breaks down into the following categories: Legacy code - No longer used (Systems that have been retired or replaced, etc) Legacy code - In current use (No intentions for upgrades or minor bug fixes, only major fixes if needed) Current code - In current use, and will be used for future versions/development Support libraries - For both legacy and current code (Some of the legacy libraries are no longer available as well) We would like to migrate this to a newer versioning system as we will be adding more developers, and expanding the reach to include remote programmers. When migrating, how do you structure it? Do you just perform a dump of all the data and then import it into the new system, or do you segregate according to type before you bring it into the new system? Do you set up a separate area for libraries, or keep them with the relevant packages? Do you separate by language, system, both? A general outline and methodology is fine, it doesn't need to be broken down to individual program level.

  • You Can&rsquo;t Upload An Empty File To SharePoint 2007 Or SharePoint 2010

    - by Brian Jackett
    The title of this post is pretty self explanatory, but I thought it worth mentioning since I had never run across this rule until just recently.  A few weeks ago I was testing out a new workflow attached to a SharePoint 2007 document library.  I uploaded various file types to ensure all were handled properly.  One of the files I happened to test with was an empty .txt file to which I got the following error.      As you can see from the error message you aren’t allowed to upload a file that is empty.  Fast forward to this week when I was doing some research for my upcoming SharePoint 2010 beta exams.  I remembered that error I got a few weeks ago and decided to try out with SharePoint 2010 as well.  No surprises I got a similar error. Conclusion     Next time you are uploading files to a SharePoint 2007 or 2010 document library, make sure the file is not empty.  Coincidentally when I tweeted about this issue a few friends replied that they had also found this error recently.  I don’t know the internal reasoning why this is prevented but I assume it has something to do with how the blob for the file is stored in the database.  I assume that this would still be the case even if you had Remote Blob Storage (RBS) configured for your farm, but don’t have access to such a farm to confirm.  If anyone reading this does have access and wants to confirm that would be appreciated, just leave a comment.         -Frog Out

  • Why would Java app make RPC call to itself?

    - by amphibient
    I am working with a multithreaded homegrown multi-module app in my new job. We use the the Thrift protocol to communicate RPC calls between different stand-alone applications in a distributed system. One of them listens on multiple ports and I just noticed that it actually makes an RPC call to itself from one thread invoked from one socket it listens to (web service call) to another port within the same app. I verified that it could accomplish the same thing if it just went and directly called the method that the remote procedure ultimately invokes as it is all within the same application, same JVM. To make it even more mysterious, the call is completely synchronous, i.e. no callbacks involved. The first thread totally sits and waits until it makes a call across the wire to itself and comes back. Now, I am perplexed why anybody would do it this way. It seems like calling somebody on the phone that sits in the same room as you do. Can anybody provide an explanation why the developer before me would come up with the above mentioned model? Maybe there is a reason and I am missing something.

  • Display Problems running Ubuntu 12.04 in Windows VMware Player

    - by Alex Reynolds
    I am posting this again because I have changed to VMWare Player and I discovered something new. I am running Ubuntu 12.04 LTS (Guest) in VMWare Player 6.0.2 on Windows 7 64-bit Host. I have VMWare Tools installed properly. I am running MATE but the problem persists when I change (to and from) xfce, gnome, mate a-- and back again I had been using this for a couple of years without any graphics issues. After an Ubuntu update (typical) -- my video is corrupt and will not refresh correctly. My desktop icons are "mirrored" and when I open a terminal window (for instance) -- sometimes -- the window appears multiple times. Of course, only one is the real image. It seems to be a refresh problem. When I move an active window around the screen the "older" images "erase" and my icons (for instance) are in the correct location. For instance, I can move the terminal around a pretty corrupted window and the screen behind it is repainted correctly. NEW: Next, I got the idea to try and Remote Desktop in to the Ubuntu 12.04 LTS Guest OS from my Windows 7 64-bit Host. Once working, and connected via Win RDC -- using MATE as default in my /etc/xrdp/startws.sh -- my video is not corrupted and works fine (as in the past). Any ideas about what is going on ? or how to fix this ?

  • Limitations of the SharePoint join using CAML

    - by ybbest
    Limitation One In SharePoint 2010, you can join the primary list to a foreign list and include more than one field from the foreign list. However, the limitation is that the included fields from foreign list have to be the following type: Calculated (treated as plain text) ContentTypeId Counter Currency DateTime Guid Integer Note (one-line only) Number Text The above limitation also explains why you cannot include some types of the fields from the remote list when creating a lookup. Limitation Two When using CAML query to join SharePoint lists, there can be joins to multiple lists, multiple joins to the same list, and chains of joins. However, the limitations are only inner and left outer joins are permitted and the field in the primary list must be a Lookup type field that looks up to the field in the foreign list. Limitation Three The support for writing the JOIN query in CAML is very limited.I have to hand-code the CAML query to join the lists,not fun at all.Although some blogs post mentioned about using LINQ to SharePoint and get the CAML code from there , but I never get it to work.You can check this blog post  for this.Let me know if it works for you.

  • IPv6 tunnels - any easy way to turn them on and off?

    - by Rob Hoare
    I've set up a tunnelbroker.net (Hurricane Electric) IPv6 tunnel from my laptop running 12.04. Works fine, and allows me to test the dual-stack configuration on my remote webservers etc. until native IPv6 is available on my ISP. However, there are times when I don't want the tunnel. For example if I'm accessing something that requires an IPv4 address in my own country rather than the Tunnelbroker tunnel endpoint, or if I'm away from the local IPv4 tunnel endpoint, or if I simply want to test without IPv6. Is there a simple way to disable and then re-enable the IPv6 tunnel, without rebooting? For context, here's what's in my /etc/network/interfaces (NNN replaces numbers): auto he-ipv6 iface he-ipv6 inet6 v4tunnel endpoint 216.218.NNN.NNN address 2001:470:NNN:NNN::2 netmask 64 up ip -6 route add default dev he-ipv6 down ip -6 route del default dev he-ipv6 Is there a network manager application (gui or command line) to selectively enable/disable parts of /etc/network/interfaces, or IPv6 in general? I found even by commenting out that out (and reloading networking) it's tough to get the IPv6 to go away. A "tunnel on/off" button in networking would be great, like using a VPN.

  • Is it safer to use the same IV all times data are encrypted, or use a dynamic IV that is sent together the encrypted text? [closed]

    - by kiamlaluno
    When encrypting data that is then send to a server, is it better to always use the same IV, which is already known from the receiving server, or use a dynamic IV that is then sent to the receiving server? I am referring to the case the remote server receives data from another server, or from a client application, and executes operations on a database table, in the table row identified by the received data. Which of the following PHP snippets is preferable? $iv = mcrypt_create_iv(mcrypt_enc_get_iv_size($td), MCRYPT_RAND); $ks = mcrypt_enc_get_key_size($td); $key = substr(md5('very secret key'), 0, $ks); mcrypt_generic_init($td, $key, $iv); $encrypted = mcrypt_generic($td, 'This is very important data'); send_encripted_data(combine_iv_encrypted_text($iv, $encrypted)); $ks = mcrypt_enc_get_key_size($td); $key = substr(md5('very secret key'), 0, $ks); mcrypt_generic_init($td, $key, $iv); send_encripted_data(mcrypt_generic($td, 'This is very important data')); In which way is one of the snippets more vulnerable than the other one?

  • dpkg in uninterruptible sleep

    - by Khaled
    I have several Ubuntu servers 10.04. Today, I tried to upgrade some packages on one of these servers and the process got stuck. I logged in using another SSH session and I found that dpkg is in D state (uninterruptible sleep). According to what I have read, this state results generally from I/O waiting like waiting for NFS share. I can not understand why dpkg will block in this state. I can not see any obvious problems other than this. Here is the output of ps to show the blocking process: $ ps axo pid,cmd,s,wchan | grep dpkg 22571 /usr/bin/dpkg --status-fd 2 D call_rwsem_down_read_failed This process can not be killed even with kill -9. So, I will not be able to install/upgrade any package unless I reboot the server. What makes it worse is that the remote reboot does not succeed in such a case (having processes in D state). Can anyone help with this? How can I avoid this in the future.

  • What's the best way to manage error logging for exceptions?

    - by Peter Boughton
    Introduction If an error occurs on a website or system, it is of course useful to log it, and show the user a polite message with a reference code for the error. And if you have lots of systems, you don't want this information dotted around - it is good to have a single centralised place for it. At the simplest level, all that's needed is an incrementing id and a serialized dump of the error details. (And possibly the "centralised place" being an email inbox.) At the other end of the spectrum is perhaps a fully normalised database that also allows you to press a button and see a graph of errors per day, or identifying what the most common type of error on system X is, whether server A has more database connection errors than server B, and so on. What I'm referring to here is logging code-level errors/exceptions by a remote system - not "human-based" issue tracking, such as done with Jira,Trac,etc. Questions I'm looking for thoughts from developers who have used this type of system, specifically with regards to: What are essential features you couldn't do without? What are good to have features that really save you time? What features might seem a good idea, but aren't actually that useful? For example, I'd say a "show duplicates" function that identifies multiple occurrence of an error (without worrying about 'unimportant' details that might differ) is pretty essential. A button to "create an issue in [Jira/etc] for this error" sounds like a good time-saver. Just to re-iterate, what I'm after is practical experiences from people that have used such systems, preferably backed-up with why a feature is awesome/terrible. (If you're going to theorise anyway, at the very least mark your answer as such.)
