• Message Passing Interface (MPI)

  So you have installed your cluster and you are done with introductory material on Windows HPC. Now you want to develop an application with the most common programming model: Message Passing Interface.The MPI programming model is a standard with implementations from many vendors.

• vsftpd: chroot_local_user causes GNU/TLS-error

  - by akrosikam

  Distro: Ubuntu 12.04.2 Server 32-bit Server client: vsftpd 2.3.5 (from default "main" repository) Problem: Since upgrading from Ubuntu 10.04 to Ubuntu 12.04 (nothing changed on client-side), vsftp has refused to make chroot-jails with the "chroot_local_user" directive on FTP(e/i)S-connections. Here's my vsftpd.conf: anonymous_enable=NO local_enable=YES write_enable=YES local_umask=022 dirmessage_enable=YES xferlog_enable=YES xferlog_std_format=YES ftpd_banner=How are you gentlemen. listen=YES pam_service_name=vsftpd userlist_enable=YES userlist_deny=NO tcp_wrappers=YES connect_from_port_20=YES ftp_data_port=20 listen_port=21 pasv_enable=YES pasv_promiscuous=NO pasv_min_port=4242 pasv_max_port=4252 pasv_addr_resolve=YES pasv_address=your.domain.com ssl_enable=YES allow_anon_ssl=NO force_local_logins_ssl=YES force_local_data_ssl=YES ssl_tlsv1=YES ssl_sslv2=NO ssl_sslv3=NO rsa_cert_file=/home/maw/ssl_ftp_test/vsftpd.pem rsa_private_key_file=/home/maw/ssl_ftp_test/vsftpd.pem debug_ssl=YES log_ftp_protocol=YES ssl_ciphers=HIGH chroot_local_user=NO How to reproduce: Have a working SSL/TLS-secured vsftpd-configuration (I suggest similar to the one above) ready. Try to connect with an FTP user client and upload some files. With my setup, the above listed config works well at this point. Edit /etc/vsftpd.conf and set chroot_local_user= to YES. Make sure that chroot_list_enable= and/or chroot_list_file= are not set. Comment them out if they are. Save and exit. Run sudo restart vsftpd (or sudo service vsftpd restart if you like) in a terminal. Try to connect with an FTP user client. You should see a message more or less like this: GnuTLS error -15: An unexpected TLS packet was received. This is an issue for me, as I do not want FTP-sessions to be able to list files outside the user's home folder. I have checked with several client-side apps, and I get the same results with every one of them. Filezilla is not so good regarding cipher methods nowadays, but as I am able to make an FTP(e)s-connection over TLS (as long as chroot'ing is disabled and ssl_ciphers is set to HIGH) I have a feeling ciphers are not the issue this time, and that I won't find the answer by tweaking configs on the client side. My vsftpd.log stays empty, even though debug_ssl and log_ftp_protocol are enabled, so no info there either.

• CodeCritics.com: A no nonsense place for coders to critique code and raise awareness of standards and "good coding standards" [closed]

  - by Visionary Software Solutions

  StackOverflow has been a boon for increasing programming knowledge by allowing developers to ask for help and knowledge related to programming. Oftentimes these questions boil down to: This code is broken, fix it I don't know how to do this Is this the best approach (hard question to answer on StackExchange, but democratic) Oftentimes, however, these questions are discussed at a very high level. "I use web services with a proxy client to ..." But, as Grady Booch is fond of saying "the Truth is raw, naked, running code". Those high level descriptions can be accomplished in any ways. Programming is an Art, and there are an infinite number of different ways to do things. But some are better than others. A site devoted to Q&A can help increase knowledge...a site devoted to critique of code can help elevate standards and result in higher quality knowledge. By upvoting the most elegant ways to solve a short, concise problem statement, or just looking at a piece of code and saying "this is ugly, how can we fix it?" we can increase community participation in discussions about the substantive details of an approach: "is my commenting clear? "Is this 3 nested for-loops with a continue that breaks in a special case a good way of building an object?" "Does this extremely generic and polymorphic inheritance hierarchy have issues?") Code is an art/craft and science/engineering artifact. Doesn't it deserve the same type of review treatment as a painting and an experiment? For praising those that provide that moment of zen when looking at exceptionally good code that makes you believe in a better tomorrow, and panning those whose offal is so offensive that were you to meet them on the job you'd say "YOU! GET OUT!!!" Hence, CodeCritics. A collaborative critiquing platform in the style of StackOverflow focused solely on critiquing code that can act as a collaborative code review and assist in the discovery of Design Patterns.

• Unity 3D (with Nvidia driver) becomes very slow and laggy

  - by Graham

  How can I prevent my Unity 3D desktop from becoming slow after a while, given that I have an Nvidia Quadro NVS 290 graphics in TwinView mode? The desktop starts out fast on login, but becomes slow / lagging / hesitant / high latency after a while, symptoms being spikes in CPU usage by /usr/bin/X whenever I cause any graphical activity with the mouse or keyboard (e.g. typing, changing tabs, dragging windows). The desktop remains slow even with all windows (except htop in Terminal) and extraneous processes killed. Detail: Changing tabs in Terminal takes about a second, and X spikes to 76% CPU. As I type into Firefox, X spikes to 95% CPU. Dragging Termiinal window, X goes to 70% CPU. Basically, every graphical action sends CPU usage of X through the roof. Device: Nvidia Quadro NVS 290 Driver package: binary driver nvidia-current-updates (280.13-0ubuntu5) Dual Monitors: Pair of DELL UltraSharp 1908FP in TwinView (X screen 2560x1024) OS: Fresh install of Ubuntu 11.10 amd64 Desktop with all updates. Hardware: Dell Precision T5400 Workstation Pastebin of Xorg.0.log Pastebin of xorg.conf Pastebin of nvidia-xconfig -t output (easier to read than xorg.conf) Output of /usr/lib/nux/unity_support_test -p: To obtain the following htop screenshow I typed "asdf" several times in in this text box, alt-tabbed to Terminal and took a screenshot of the high X CPU usage. This also happens when firefox is not running: Quadro NVS 290 has "No" thermal sensor according to sensors-detect: Next adapter: NVIDIA i2c adapter 0 at 2:00.0 (i2c-0) Do you want to scan it? (YES/no/selectively): Client found at address 0x50 Probing for `Analog Devices ADM1033'... No Probing for `Analog Devices ADM1034'... No P robing for `SPD EEPROM'... No Probing for `EDID EEPROM'... Yes (confidence 8, not a hardware monitoring chip) I tried the nouveau driver by disabling the nvidia-current-updates under Additional Drivers, but Ubuntu and xrandr -q fail to detect the second monitor. This may be issue 737349. Funniest thing is that Nouveau wiki says that XRandR 1.2 dual-monitor is supported so it should work with a second monitor.

• What is the best strategy for transforming unicode strings into filenames?

  - by David Cowden

  I have a bunch (thousands) of resources in an RDF/XML file. I am writing a certain subset of the resources to files -- one file for each, and I'm using the resource's title property as the file name. However, the titles are every day article, website, and blog post titles, so they contain characters unsafe for a URI (the necessary step for constructing a valid file path). I know of the Jersey UriBuilder but I can't quite get it to work for my needs as I detailed in a different question on SO. Some possibilities I have considered are: Since each resource should also have an associated URL, I could try to use the name of the file on the server. The down side of this is sometimes people don't name their content logically and I think the title of an article better reflects the content that will be in each text file. Construct a white list of valid characters and parse the string myself defining substitutions for unsafe characters. The downside of this is the result could be just as unreadable as the former solution because presumably the content creators went through a similar process when placing the files on their server. Choose a more generic naming scheme, place the title in the text file along with the other attributes, and tell my boss to live with it. So my question here is, what methods work well for dealing with a scenario where you need to construct file names out of strings with potentially unsafe characters? Is there a solution that better fills out my constraints?

• IoT end-to-end demo – Remote Monitoring and Service By Harish Doddala

  - by JuergenKress

  Historically, data was generated from predictable sources, stored in storage systems and accessed for further processing. This data was correlated, filtered and analyzed to derive insights and/or drive well constructed processes. There was little ambiguity in the kinds of data, the sources it would originate from and the routes that it would follow. Internet of Things (IoT) creates many opportunities to extract value from data that result in significant improvements across industries such as Automotive, Industrial Manufacturing, Smart Utilities, Oil and Gas, High Tech and Professional Services, etc. This demo showcases how the health of remotely deployed machinery can be monitored to illustrate how data coming from devices can be analyzed in real-time, integrated with back-end systems and visualized to initiate action as may be necessary. Use-case: Remote Service and Maintenance Critical machinery once deployed on the field, is expected to work with minimal failures, while delivering high performance and reliability. In typical remote monitoring and industrial automation scenarios, although many physical objects from machinery to equipment may already be “smart and connected,” they are typically operated in a standalone fashion and not integrated into existing business processes. IoT adds an interesting dynamic to remote monitoring in industrial automation solutions in that it allows equipment to be monitored, upgraded, maintained and serviced in ways not possible before.

• Workflow: Operate Zones

  - by Owen Allen

  The Operate Zones workflow is another of the workflow documents that we introduced recently. It follows naturally after the Deploy Oracle Solaris 11 Zones workflow that I talked about last week, so I thought I'd talk about it next. This workflow is less linear than the zone deployment workflow. It's built around this image: The left side shows you the prerequisites for zone operation: you have to deploy libraries and deploy either Oracle Solaris 10 or 11 zones - whichever type you want to manage using this workflow. Once you have the zones deployed, you can begin to operate them. If you want to associate resources with the global zone, the workflow directs you to the Exploring Your Server Pools how-to, which talks about adding global zones to server pools and associating libraries and network resources with them. Otherwise, it directs you to a set of how-tos about zone management: Managing the Configuration of a Zone, which explains how to add storage, edit zone attributes, and connect zones to networks; Lifecycle Management of Zones, which explains how to halt, shut down, boot, reboot, or delete a zone; and Migrating Zones, which explains how to move a zone to a new global zone in the same server pool. Finally, it directs you to the Update Oracle Solaris workflow when you want to update your zones, and to the Monitor and Manage Incidents workflow to learn more about monitoring your assets.

• Munq is for web, Unity is for Enterprise

  - by oazabir

  The Unity Application Block (Unity) is a lightweight extensible dependency injection container with support for constructor, property, and method call injection. It’s a great library for facilitating Inversion of Control and the recent version supports AOP as well. However, when it comes to performance, it’s CPU hungry. In fact it’s so CPU hungry that it makes it impossible to make it work at Internet Scale. I was investigating some CPU issue on a portal that gets around 3MM hits per day and I found unusually high CPU. Here’s why: I did some CPU profiling on my open source project Dropthings and found that the highest CPU is consumed by Unity’s Resolve<>(). There’s no funky use of Unity in the project. Straightforward Register<>() and Resolve<>(). But as you can see, Resolve<>() is consuming significantly high CPU even after the site is warm and has been running for a while. Then I tried Munq, which is a basic Dependency Injection Container. It has everything you will usually need in a regular project. It boasts to be the fastest DI out there. So, I converted all Unity code to Munq in Dropthings and did a CPU profile and Whala!   There’s no trace of any Munq calls anywhere. That proves Munq is a lot faster than Unity.

• Instructor Insight: Using the Container Database in Oracle Database 12 c

  - by Breanne Cooley

  The first time I examined the Oracle Database 12c architecture, I wasn’t quite sure what I thought about the Container Database (CDB). In the current release of the Oracle RDBMS, the administrator now has a choice of whether or not to employ a CDB. Bundling Databases Inside One Container In today’s IT industry, consolidation is a common challenge. With potentially hundreds of databases to manage and maintain, an administrator will require a great deal of time and resources to upgrade and patch software. Why not consider deploying a container database to streamline this activity? By “bundling” several databases together inside one container, in the form of a pluggable database, we can save on overhead process resources and CPU time. Furthermore, we can reduce the human effort required for periodically patching and maintaining the software. Minimizing Storage Most IT professionals understand the concept of storage, as in solid state or non-rotating. Let’s take one-to-many databases and “plug” them into ONE designated container database. We can minimize many redundant pieces that would otherwise require separate storage and architecture, as was the case in previous releases of the Oracle RDBMS. The data dictionary can be housed and shared in one CDB, with individual metadata content for each pluggable database. We also won’t need as many background processes either, thus reducing the overhead cost of the CPU resource. Improve Security Levels within Each Pluggable Database  We can now segregate the CDB-administrator role from that of the pluggable-database administrator as well, achieving improved security levels within each pluggable database and within the CDB. And if the administrator chooses to use the non-CDB architecture, everything is backwards compatible, too.  The bottom line: it's a good idea to at least consider using a CDB. -Christopher Andrews, Senior Principal Instructor, Oracle University

• Monster's AI in an Action-RPG

  - by Andrea Tucci

  I'm developing an action rpg with some University colleagues. We've gotton to the monsters' AI design and we would like to implement a sort of "utility-based AI" so we have a "thinker" that assigns a numeric value on all the monster's decisions and we choose the highest (or the most appropriate, depending on monster's iq) and assign it in the monster's collection of decisions (like a goal-driven design pattern) . One solution we found is to write a mathematical formula for each decision, with all the important parameters for evaluation (so for a spell-decision we might have mp,distance from player, player's hp etc). This formula also has coefficients representing some of monster's behaviour (in this way we can alterate formulas by changing coefficients). I've also read how "fuzzy logic" works; I was fascinated by it and by the many ways of expansion it has. I was wondering how we could use this technique to give our AI more semplicity, as in create evaluations with fuzzy rules such as IF player_far AND mp_high AND hp_high THEN very_Desiderable (for a spell having an high casting-time and consume high mp) and then 'defuzz' it. In this way it's also simple to create a monster behaviour by creating ad-hoc rules for every monster's IQ category. But is it correct using fuzzy logic in a game with many parameters like an rpg? Is there a way of merging these two techniques? Are there better AI design techniques for evaluating monster's chooses?

• Ajax application: using SOAP vs REST ?

  - by coder

  I'm building an ajax heavy application (client-side strictly html/css/js) which will be getting all the data and using server business logic via webservices. I know REST seems to be the hot topic but I can't find any good arguments. The main argument seems to be its "light-weight". My impression so far is that wsdl/soap based services are more expressive and allow for more a more complex transfer of data. It appears that soap would be more useful in the application I'm building where the only code consuming the services will be the js downloaded in the client browser. REST on the other hand seems to have a smaller entry barrier and so can be more useful for services like twitter in allowing other developers to consume these services easily. Also, REST seems to Te better suited for simple data transfers. So in summary SOAP is useful for complex data transfer and REST is useful in simple data transfer. I'm currently under the impression that using SOAP would be best due to the complexity of the messages but perhaps there's other factors. What are your thoughts on the pros/cons of soap/rest for a heavy ajax web app? EDIT: While the wsdl is in xml, the data I'm transferring back and forth is actually in JSON. It just appears more natural to use wsdl/soap here due to the nature of the app. The verbs GET and POST may not be enough. I may want to say something like: processQueue, or executeTimer. This is why my conclusion has been wsdl/soap would be good for bridging a complex layer between two applications (client and server) whereas REST would be better (due to its simplicity) for allowing many developer-users to consume resources programmatically. So you could say the choice falls along two lines Will the app be verb-oriented (completing tasks: use soap) or noun-oriented (consuming resources: use REST) Will the api be consumed by few developers or many developers (REST is strong for many developers)? Since such an ajax heavy app would potentially use many verbs and would only be used by the client developer it appears soap/wsdl would be the best fit.

• What about introduction to programming with C# via LINQPad?

  - by Gulshan

  From different questions/answers/articles in this and some other sites, I got the idea that the introductory language for programming should be- High level Less verbose C# is one of the heavily used high level languages being used these days. It's also multi-paradigm and descendant of C, the lingua-franca of all programming languages. So, I think it has the potential to be the introductory programming language. But I felt it's a bit verbose for the novice learners. Then LINQPad came into my mind. With LINQPad, someone can start with C# without it's verbosity. Because you can just run one statement or few statements or a standalone function with LINQPad. Again you can run a full source file also. Another thing it provide is- using SQL. So, it can be used for learning SQL too. And not to mention, it's free. So, what you guys think about the idea of introducing programming with C# via LINQPad? Any thing to watch out? Any suggestion?

• How to Best Optimize up Model Transforms, Import 3DS Animations Into XNA 4.0?

  - by Jason R. Mick

  Relative beginner to XNA, but trying to build a multi-purpose (3D) game frameworking in XNA 4. Been using the Reed (O'Reilly) and Cawood/McGee (McGraw Hill) guides. My question is multi-faceted and involves how to most efficiently handle models. I'm using 3DS Max 2010 with kw-Xport to ship out my models as .X files. Solved an early problem by using my depth stencil state. My models are now loading properly (yay!) and I have basic bounding working, I just want to optimize transforming models and get animations working as a next step. My questions on models are: 1. Do you have any suggestions for good resources on exporting 3DS animations to XNA? I've seen some resources on how to handle animations in XNA, but most skimp on basic topics of how to convert multi-animation 3DS files. For example how do I take one big long string of keyframed animations (say running, frame 5-20, climbing frames 25-45, etc.) and turned them into named XNA animations. To my understanding every XNA animation has to have a name, but I haven't seen any tutorials on creating a new named animation from a subset of frames. 2. Is it faster to load a model once and animate/transform that base model on the fly @ draw time, or to load multiple models? My game will have multiple enemies, and I've already seen some lagginess in XNA, so II want to make my code efficient... 3. I've heard people on app hub talking about making custom content processors for models-- what is the benefit of this? Does it speed up transforming or animating the models? If so, can you point me towards any good (model-centric) tutorials? (I've built a custom height map content processor to generate terrain, following Cawood's examples, I'm just a bit confused as to how a model content processor would be implemented.)

• After update, flash plugin playing video too fast or too slow

  - by John H

  Last night I did an update and reboot. After that, I couldn't reliably play any flash videos. They would either go too fast or stutter (as if they were buffering every 2 seconds). This occurs in both Firefox and Chrome, however I'll troubleshoot in Chrome because it's easier to enable/disable plugins at will. With PPAPI enabled (and npapi disabled), flash videos play at 1.5x speeds and audio is scrambled. With NPAPI enabled (and ppapi disabled), flash videos stutter and skip, despite showing a decent buffer. From one old thread, I went into pavucontrol and tried disabling the high def audio controller. I also tried disabling Totem plugin to no affect. Version other details: Linux freshdesk 3.2.0-29-generic #46-Ubuntu SMP Fri Jul 27 17:03:23 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux $ cat /etc/*-release DISTRIB_ID=Ubuntu DISTRIB_RELEASE=12.04 DISTRIB_CODENAME=precise DISTRIB_DESCRIPTION="Ubuntu 12.04.1 LTS" Shockwave Flash 11.3 r31 /opt/google/chrome/PepperFlash/libpepflashplayer.so 11.3.31.331 PPAPI (out-of-process) Shockwave Flash Version: 11.2 r202 Location: /usr/lib/adobe-flashplugin/libflashplayer.so Type: NPAP 01:00.0 VGA compatible controller: NVIDIA Corporation GT218 [GeForce 8400 GS] (rev a2) 01:00.1 Audio device: NVIDIA Corporation High Definition Audio Controller (rev a1)
