  • Python: how to calculate data received and send between two ipaddresses and ports [closed]

    - by ramdaz
    I guess it's socket programming. But I have never done socket programming expect for running the tutorial examples while learning Python. I need some more ideas to implement this. What I specifically need is to run a monitoring program of a server which will poll or listen to traffic being exchange from different IPs across different popular ports. For example, how do I get data received and sent through port 80 of 192.168.1.10 and 192.168.1.1 ( which is the gateway). I checked out a number of ready made tools like MRTG, Bwmon, Ntop etc but since we are looking at doing some specific pattern studies, we need to do data capturing within the program. Idea is to monitor some popular ports and do a study of network traffic across some periods and compare them with some other data. We would like to figure a way to do all this with Python....

  • Computer hanged in the middle of bios flashing process

    - by Stalker
    I have a laptop: Toshiba Satellite c660-17j, today I decided to update BIOS. I've downloaded bios updater from manufacturer's web site, and in the middle of flashing process computer hanged. I was waiting more than 30 minutes, but nothing was changed on the screen, i've tryed to PRESS MORE BUTTONS, but there were no reactions, so i've turned it off by removing battery (all other methods failed, even pressing power button for ~10 secs). After that computer can't start. I understand, that there's MESS in BIOS chip, and it's possible to re-flash it with hardware programmer, but I don't have it. I remember, that on some PCs (even on my eeepc) there was possibility to re-flash bios by inserting usb flash-disk (with .dat file on it, which contained BIOS), and power on PC, while holding some keys combination, then PC was switching to BIOS programming mode and re-flashed BIOS, after that it was possible to boot up normaly. Is there a way to recover computer without hardware programming BIOS chip? p.s. sorry for my english.

  • Why no Win16 support in 64-bit Windows?

    - by dsimcha
    My understanding (from Wikipedia) is that the x64 instruction set supports executing 16-bit protected mode code from long mode, but cannot execute real mode code without being switched out of long mode because long mode lacks virtual 8086 mode. Therefore, it stands to reason that real mode DOS apps can't be run in Win64 w/o software emulation or dynamic translation. However, why was support for Win16 protected-mode apps excluded when support for them seems (at least at first glance) to be reasonably implementable and is included in newer versions of Win32? Was it just a matter of demand not being high enough to justify implementation costs (and the win32 version was already implemented), or is there a good technical reason?

  • XDMCP is slow any ideas? (looking for alternative remote desktops)

    - by peteri
    I've been used to using RDP on Windows to remote to machines, and I've got an asus eee 701 which I want to use to do some *nix programming on. While the eee is a lovely little machine the screen and keyboard are a little small to use for lots of programming. I've tried using Xming (the free version) to remote login into the eee from my desktop using XDMCP (or even using a ssh session as a straight X11 server and no desktop on the eee) the whole thing seems seriously slow over wifi the initial desktop takes at least 5 seconds to paint (might even be 10 seconds I haven't actually timed it). So my real question is what do other folks use for remote control with a GUI for their *nix boxes? I am finding it hard to believe the performance is so bad over a wifi network (It makes the Mac IIs I used to use a college in 1988 seem fast) or is this just a problem with Xming and using say the Cygwin X11 server would be better.

  • Create and redirect subdomain for a parked domain?

    - by Steve
    I have a domain parked.com which is parked onto real.com. I have created the subdomain m.parked.com by editing parked.com's named file: m 14400 IN A ip-address www.m 14400 IN A ip-address This works somewhat: if I go to m.parked.com it redirects to http://m.parked.com/cgi-sys/defaultwebpage.cgi This is my question: I would like to redirect this subdomain to real.com as that is the domain it is parked on. I do not know how to do this as parked.com does not have its own .htaccess file, etc. (due to it being a parked domain) so I can't do any mod_rewrite magic. Can anyone help me? Thanks EDIT: Clarification

  • Manage Large E-Book Archive

    - by Cnkt
    I have a very large e-book archive (approx. 1TB) including various file formats eg. PDF, DJVU, MOBI and EPUB. I put them in different folders by subject eg. Engineering, Programming etc. But after many years, things are going crazy. The programming folder itself is 220GB and file names are cryptic. Some filenames are well defined like: 236659889_Final_Report_of_2012_Climate_Change_Conference.pdf but some filenames are just ISBN numbers or just download.pdf. I need an application for organizing and searching my e-books. I already tried Calibre, Mendeley and Debenu. But all these apps try to import files first and I dont have any spare 1+ TB for the apps import folder. Is there any good Windows application for just indexing filenames and contents of ebooks without importing them?

  • Linux periodically "losing" ability to connect to server via SSH?

    - by gct
    I know this isn't exactly a programming question, but it popped up in my use of git for programming projects at least. I've got a web server that I use to host my git repos on, but my ubuntu box seems to "lose" the ability to connect to it via SSH. I'll get a "connection refused" error when I try to ssh or use git. Rebooting my local machine will fix the problem, but only temporarily. I can still connect to the web interface just fine, and the problem manifests with other servers as well. I've been working around it by pulling my changes over to my laptop and pushing from there, but that's sub-optimal as you can imagine. Has anyone seen something like this? I'd be tempted to say it's some kind of IP caching problem, but I can't connect even using the IP address of the server directly... Running Ubuntu 9.04

  • Equalizer for Toshiba Satellite Pro Laptop (Windows 7) (has Realtek sound)

    - by Need Help
    Hi, I've been trying to find a way to have a real equalizer for my Toshiba Satellite Pro Laptop. I don't know much about computers but the guys in the store seem to know less than I do! From what I've been able to glean through friends, Windows 7 no longer supports a real equalizer function with Realtek, and the result is a fake "equalizer" that does nothing. I have hearing issues so not being able properly adjust the higher frequencies is causing me physical pain and ringing in my ears. I've tried to decipher the threads I find online but am quite confused by them. Basically I need an equalizer that will work with Windows 7 (with everything, internet, skype, music, etc). The current drivers offered by Realtek do nothing except make the sound inaudible. The one that may possibly work and provide an actual equalizer is a few versions back and can't be found anywhere. Thanks! And sorry if this is a duplicate question but I am confused a bit by the threads online.

  • Is there a difference in page fault rates between CPU bound and I/O bound processes?

    - by user198864
    I was thinking, should there be any difference in expectation of the page fault rate on CPU-bound vs I/O bound processes? At first I thought maybe we could, since CPU-bound processes would likely be using more memory accesses per time quantum, so I expect it would move from locality to locality faster. At the same time, the CPU-bound process is probably given a larger working set... but this doesn't affect the fault overhead as it hits a new locality IF this wasn't pre-paged in. Is there actually any real difference in the page fault rates or am I just musing about something nonexistent? And if there is, how would it impact a real-world OS like linux?

  • Learning HTML5 - Sample Sites

    - by Albers
    Part of the challenge with HTML5 is understanding the range of different technologies and finding good samples. The following are some of the sites I have found most useful. IE TestDrive http://ie.microsoft.com/testdrive/ A good set of demos using touch, appcache, IndexDB, etc. Some of these only work with IE10. Be sure to click the "More Demos" link at the bottom for a longer list of Demos in a nicely organized list form. Chrome Experiments http://www.chromeexperiments.com/ Chrome browser-oriented sumbitted sites with a heavy emphasis on display technologies (WebGL & Canvas) Adobe Expressive Web http://beta.theexpressiveweb.com/ Adobe provides a dozen HTML5 & CSS3 samples. I seem to end up playing the "Breakout" style Canvas demo every time I visit the site. Mozilla Demo Studio https://developer.mozilla.org/en-US/demos/tag/tech:html5/ About 100 varied HTML5-related submitted web sites. If you click the "Browse By Technology" button there are other samples for File API, IndexedDB, etc. Introducing HTML5 samples http://html5demos.com/ Specific Tech examples related to the "Introducing HTML5" book by Bruce Lawson & Remy Sharp HTML5 Gallery http://html5gallery.com/ HTML5 Gallery focuses on "real" sites - sites that were not specifically intended to showcase a particular HTML5 feature. The actual use of HTML5 tech can vary from link to link, but it is useful to see real-world uses. FaceBook Developers HTML5 Showcase http://developers.facebook.com/html5/showcase/ A good list of high profile HTML5 applications, games and demos (including the Financial Times, GMail, Kindle web reader, and Pirates Love Daisies). HTML5 Studio http://studio.html5rocks.com/ Another Google site - currently 14 samples of concepts like slideshows, Geolocation, and WebGL using HTML5.

  • Enum.HasFlag method in C# 4.0

    - by Jalpesh P. Vadgama
    Enums in dot net programming is a great facility and we all used it to increase code readability. In earlier version of .NET framework we don’t have any method anything that will check whether a value is assigned to it or not. In C# 4.0 we have new static method called HasFlag which will check that particular value is assigned or not. Let’s take an example for that. First I have created a enum called PaymentType which could have two values Credit Card or Debit Card. Just like following. public enum PaymentType { DebitCard=1, CreditCard=2 } Now We are going to assigned one of the value to this enum instance and then with the help of HasFlag method we are going to check whether particular value is assigned to enum or not like following. protected void Page_Load(object sender, EventArgs e) { PaymentType paymentType = PaymentType.CreditCard; if (paymentType.HasFlag(PaymentType.DebitCard)) { Response.Write("Process Debit Card"); } if (paymentType.HasFlag(PaymentType.CreditCard)) { Response.Write("Process Credit Card"); } } Now Let’s check out in browser as following. As expected it will print process Credit Card as we have assigned that value to enum. That’s it It’s so simple and cool. Stay tuned for more.. Happy Programming..

  • Extended JMS Support

    - by ACShorten
    In a previous post I discussed the real time JMS integration we added in FW4.1 and also as patches for FW2.2. There are some additional aspects of this integration I did not mention which may be of interest: JMS Topic Support - In the post I concentrated on talking about JMS Queue support but failed to mention that the MDB and outgoing real time JMS also supports JMS Topics. JMS Queues are typically used for point to point decoupled integration and JMS Topics are used for hub integration that uses Publish and Subscribe. JMS Selector Support - By default the MDB will process every message from a JMS resource (Queue or Topic). If you want to alter this behaviour to selectively filter JMS messages then you can use JMS Selectors to specify the conditions for the MDB to selectively process JMS messages based upon conditions. JMS Selectors allow filters to be specified on elements in the JMS Header and JMS Message Properties using SQL like syntax. Note: JMS Selectors do not support filters on the body elements. JMS Header Support - It is possible to place custom information in the JMS Header and JMS Message Properties for outgoing messages (so that other applications can use JMS selectors if necessary as well). This is only available when installing Patches 11888040 (FW4.1) and 11850795 (FW2.2). These facilities coupled with the JMS facilities described in the previous posts gives the product integration capabilities in JMS which can be used with configuration rather than coding. Of course, the JMS facility I have described can also be used in conjunction with SOA Suite to provide greater levels of traceability and management.

  • DevDays ‘00 The Netherlands day #1

    - by erwin21
    First day of DevDays 2010, I was looking forward to DevDays to see all the new things like VS2010, .NET4.0, MVC2. The lineup for this year is again better than the year before, there are 100+ session of all kind of topics like Cloud, Database, Mobile, SharePoint, User experience, Visual Studio, Web. The first session of the day was a keynote by Anders Hejlsberg he talked about the history and future of programming languages. He gave his view about trends and influences in programming languages today and in the future. The second talk that i followed was from the famous Scott Hanselman, he talked about the basics of ASP.NET MVC 2, although it was a 300 level session, it was more like a level 100 session, but it was mentioned by Scott at the beginning. Although it was interesting to see all the basic things about MVC like the controllers, actions, routes, views, models etc. After the lunch the third talk for me was about moving ASP.NET webform applications to MVC from Fritz Onion. In this session he changed an example webform application part by part to a MVC application. He gave some interesting tips and tricks and showed how to solve some issues that occur while converting. Next and the fourth talk was about the difference between LINQ to SQL and  the ADO.NET  Entity Framework from Kurt Claeys. He gave a good understanding about this two options, the demos where in LINQ to SQL and the Entity Framework, the goal was to get a good understanding when and where to use both options. The last talk about this day was also from Scott Hanselman, he goes deeper into the features of ASP.NET MVC 2 and gave some interesting tips, the ninja black belt tips. He gave some tips about the tooling, the new MVC 2 html helper methods, other view engines (like NHaml, spark),T4 templating. With this tips we can be more productive and create web applications better and faster. It was a long and interesting day, I am looking forward to day #2.

  • Examples of temporal database designs? [closed]

    - by miku
    I'm researching various database design for historical record keeping - because I would like to implement a prototypical web application that (excessively) tracks changes made by users and let them undo things, see revisions, etc. I'd love use mercurial or git as backend (with files as records) - since they already implement the kind of append-only changes I imagine. I tried git and dulwich (python git API) - and it went ok - but I was concerned about performance; Bi-temporal database design lets you store a row along with time periods, when this record was valid. This sure sound more performant than to operate on files on disk (as in 1.) - but I had little luck finding real-world examples (e.g. from open source projects), that use this kind of design and are approachable enough to learn from them. Revisions à la MediaWiki revisions or an extra table for versions, as in Redmine. The problem here is, that DELETE would take the whole history with it. I looked at NoSQL solutions, too. With a document oriented approach, it would be simple to just store the whole history of an entity within the document itself - which would reduce design plus implementation time in contrast to a RDBMS approach. However, in this case I'm a bit concerned about ACID-properties, which would be important in the application. I'd like ask about experiences about real-world and pragmatic designs for temporal data.

  • Turning a board game idea into a browser based, slow paced gameplay

    - by guillaume31
    Suppose I want to create a strategy game with global mutable state shared between all players (think game board). But unlike a board game, I don't want it to be real time action and/or turn-based. Instead, players should be able to log in at any time of the day and spend a fixed number of action points per day as they wish. As opposed to a few hours, game sessions would run over a few weeks. This is meant to reward good strategy rather than time spent playing (as an alternative, hardcore players could always play multiple games in parallel instead) as well as all kind of issues related to live playing like disconnections and synchronization. The game should remain addictive still have a low time investment footprint for casual players. So far so good, but this still leaves open the question of when to solve actions and when they should be visible. I want to avoid "ninja play" like doing all your moves just a few minutes before daily point reset to take other players by surprise, or people spamming F5 to place a well-timed action which would defeat the whole point of a non real-time game. I thought of a couple of approaches to that : Resolve all events in a single scheduled process running once a day. This basically means a "blind" gameplay where players can take actions but don't see their results immediately. The thing is, I played a similar browser game a few years ago and didn't like the fact that you feel disconnected and powerless until there's that deus ex machina telling you what really happened during all that time. You see the world evolve in large increments of one day, which often doesn't seem like seeing it evolve at all. For actions that have an big impact on the game or on other players (attacks, big achievements), make them visible to everyone immediately but delay their effect by something like 24 hours. Opposing players could be notified when such an event happens, so that they can react to it. Do you have any other ideas how I could go about solving this ? Are there any known approaches in similar existing games ?

  • Super Computer Built from Raspberry Pi Boards and LEGO Bricks

    - by Jason Fitzpatrick
    It was only a matter of time before someone chained together dozens of Raspberry Pi boards into a serviceable super computer; read on to see how a team of Southampton scientists built a 64-core machine using them. Image courtesy of Simon Cox and the University of Southampton. From the University of South Hampton press release: Professor Cox comments: “As soon as we were able to source sufficient Raspberry Pi computers we wanted to see if it was possible to link them together into a supercomputer. We installed and built all of the necessary software on the Pi starting from a standard Debian Wheezy system image and we have published a guide so you can build your own supercomputer.” The racking was built using Lego with a design developed by Simon and James, who has also been testing the Raspberry Pi by programming it using free computer programming software Python and Scratch over the summer. The machine, named “Iridis-Pi” after the University’s Iridis supercomputer, runs off a single 13 Amp mains socket and uses MPI (Message Passing Interface) to communicate between nodes using Ethernet. The whole system cost under £2,500 (excluding switches) and has a total of 64 processors and 1Tb of memory (16Gb SD cards for each Raspberry Pi). Professor Cox uses the free plug-in ‘Python Tools for Visual Studio’ to develop code for the Raspberry Pi.

  • Visual Basic 2010 Language Enhancements

    Earlier this month Microsoft released Visual Studio 2010, the .NET Framework 4.0 (which includes ASP.NET 4.0), and new versions of their core programming languages: C# 4.0 and Visual Basic 10 (also referred to as Visual Basic 2010). Previously, the C# and Visual Basic programming languages were managed by two separate teams within Microsoft, which helps explain why features found in one language was not necessarily found in the other. For example, C# 3.0 introduced collection initializers, which enable developers to define the contents of a collection when declaring it; however, Visual Basic 9 did not support collection initializers. Conversely, Visual Basic has long supported optional parameters in methods, whereas C# did not. Recently, Microsoft merged the Visual Basic and C# teams to help ensure that C# and Visual Basic grow together. As explained by Microsoft program manager Jonathan Aneja, "The intent is to make the languages advance together. When major functionality is introduced in one language, it should appear in the other as well. ... [T]hat any task you can do in one language should be as simple in the other." To this end, with version 4.0 C# now supports optional parameters and named arguments, two features that have long been part of Visual Basic's vernacular. And, likewise, Visual Basic has been updated to include a number of C# features that it was previously missing. This article explores some of these new features that were added to Visual Basic 2010.

  • Faq and Best tips Regarding Learning Database ?

    - by AdityaGameProgrammer
    For a programmer with no prior exposure to databases What would be a good database to learn Oracle vs SQLserver vs MySQLvs PostgreSQL? I have come across lot of discussion MySQL and PostgreSQL and frankly I am confused on which to start with. Are these very different, in the sense if one had to switch, would the exposure to one be counter-productive to learning the other? Is working with databases heavily platform dependent? What exactly do people mean by Data base programming vs. administration? Do people chose databases based on the programming language used for the application developed? In general, Working with databases is it implicit that we work with some server? Does the choice of databases differ when it comes to game development? If so what factors does it differ by? What are the Best Tips that you have found to be useful when learning databases Edit: Some FAQ i had and found the same on SO What should every developer know about databases? Which database if learning from scratch in 2010? For a beginner, is there much difference between MySQL and PostgreSQL What RDBMS should I learn/use? (MySql/SQL Server/Oracle etc.) To what extent should a developer learn database? How are database programmers different from other programmers? what kind of database are used in games?

  • We Don’t Need No Regions

    - by João Angelo
    If your code reaches a level where you want to hide it behind regions then you have a problem that regions won’t solve. Regions are good to hide things that you don’t want to have knowledge about such as auto-generated code. Normally, when you’re developing you end up reading more code than you write it so why would you want to complicate the reading process. I, for one, would love to have that one discussion around regions where someone convinces me that they solve a problem that has no other alternative solution, but I’m still waiting. The most frequent argument I hear about regions is that they allow you to structure your code, but why don’t just structure it using classes, methods and all that other stuff that OOP is about because at the end of the day, you should be doing object oriented programming and not region oriented programming. Having said that, I do believe that sometimes is helpful to have a quick overview of a code file contents and Visual Studio allows you to do just that through the Collapse to Definitions command (CTRL + M, CTRL + O) which collapses the members of all types; if you like regions, you should try this, it is much more useful to read all the members of a type than all the regions inside a type.

  • DirectCompute

    In my previous blog post I introduced the concept of GPGPU ending with:On Windows, there is already a cross-GPU-vendor way of programming GPUs and that is the Direct X API. Specifically, on Windows Vista and Windows 7, the DirectX 11 API offers a dedicated subset of the API for GPGPU programming: DirectCompute. You use this API on the CPU side, to set up and execute the kernels on the GPU. The kernels are written in a language called HLSL (High Level Shader Language). You can use DirectCompute with HLSL to write a "compute shader", which is the term DirectX uses for what I've been referring to in this post as "kernel".In this post I want to share some links to get you started with DirectCompute and HLSL.1. Watch the recording of the PDC 09 session: DirectX11 DirectCompute.2. If session recordings is your thing there are two more on DirectCompute from nvidia's GTC09 conference 1015 (pdf, mp4) and 1411 (mp4 plus the presenter's written version of the session).3. Over at gamedev there is an old Compute Shader tutorial. At the same site, there is a 3-part blog post on Compute Shader: Introduction, Resources and Addressing.4. From PDC, you can also download the DirectCompute Hands On Lab.5. When you are ready to get your hands even dirtier, download the latest Windows DirectX SDK (at the time of writing the latest is dated Feb 2010).6. Within the SDK you'll find a Compute Shader Overview and samples such as: Basic, Sort, OIT, NBodyGravity, HDR Tone Mapping.7. Talking of DX11/DirectCompute samples, there are also a couple of good ones on this URL.8. The documentation of the various APIs is available online. Here are just some good (but far from complete) taster entry points into that: numthreads, SV_DispatchThreadID, SV_GroupThreadID, SV_GroupID, SV_GroupIndex, D3D11CreateDevice, D3DX11CompileFromFile, CreateComputeShader, Dispatch, D3D11_BIND_FLAG, GSSetShader. Comments about this post welcome at the original blog.

  • Is there a way to track data structure dependencies from the database, through the tiers, all the way out to a web page?

    When we design applications, we generally end up with the same tiered sets of data structures: A persistent data structure that is described using DDL and implemented as RDBMS tables and columns. A set of domain objects that consist primarily of data structures, usually combined with business-rule level logic, that are implemented in a programming language such as Java. A set of service layer interfaces that directly support use case implementations (which use the domain data structures as parameters), implemented as EJBs or something equivalent in another programming language. UI screens that allow users to C reate, R etrieve, U pdate, and (maybe) D elete all manner of data structures and graphs of data structures, with numerous screens and with multiple UI widgets, all structured to support the same data structures. But if you want to change the data structures in any of these tiers, it always seems extremely difficult to assess the impact(s) the change will have across the application. UML can help, but tracing through diagram after diagram is not a real solution to this problem. The best I have ever seen was a homespun data tracking spreadsheet document that listed all of the data structures and walked the relationships from tier-to-tier. Is there a tool or accepted approach that makes it easy to identify a data structure in any tier and easily obtain a list of all dependent: database table and column data structures domain object data structures service layer interface methods and parameter data structures screen & UI component data structures

  • Oracle BPM enable BAM by Peter Paul

    - by JuergenKress
    BPMN processes created in the BPM Suite can be monitored by standardized dashboard in the BPM workspace. Besides that there a default views to export Oracle BPM metrics to a data warehouse. And there is another option: BAM – Business Activity Monitoring. BAM takes the monitoring of BPMN processes one step further. BAM allows you to create more advanced dashboards and even real-time alerts. BAM enables you to make decisions based on real-time information gathered from your running processes. With BPMN processes you can use the standard Business Indicators that the BPM Suite offers you and use them to with BAM without much extra effort. However you have to enable BAM in BPM processes.
