  • Server-side Architecture for Online Game

    - by Draiken
    basically I have a game client that has communicate with a server for almost every action it takes, the game is in Java (using LWJGL) and right now I will start making the server. The base of the game is normally one client communicating with the server alone, but I will require later on for several clients to work together for some functionalities. I've already read how authentication server should be sepparated and I intend on doing it. The problem is I am completely inexperienced in this kind of server-side programming, all I've ever programmed were JSF web applications. I imagine I'll do socket connections for pretty much every game communication since HTML is very slow, but I still don't really know where to start on my server. I would appreciate reading material or guidelines on where to start, what architecture should the game server have and maybe some suggestions on frameworks that could help me getting the client-server communication. I've looked into JNAG but I have no experience with this kind of thing, so I can't really tell if it is a solid and good messaging layer. Any help is appreciated... Thanks ! EDIT: Just a little more information about the game. It is intended to be a very complex game with several functionalities, making some functionalities a "program" inside the program. It is not an usual game, like FPS or RPG but I intend on having a lot of users using these many different "programs" inside the game. If I wasn't clear enough, I'd really appreciate people that have already developed games with java client/server architecture, how they communicated, any frameworks, apis, messaging systems, etc. It is not a question of lack of knowledge of language, more a question for advice, so I don't end up creating something that works, but in the later stages will have to be rewriten for any kind of limiting reason. PS: sorry if my english is not perfect...

  • How to split file on Windows 2003 using MS supported tool

    - by Rune
    Hi, Is it possible to split a large file into smaller files on Windows 2003 using a tool provided/supported/sanctioned by Microsoft? I see that there are a lot of freeware tools (various zip tools) for this task, but I need to move files off of a production server, thus would like to avoid tools I don't know if I can trust. I would much prefer some tool included in the Windows Server 2003 Resource Kit Tools or something along those lines. Does such a tool exist? Thank you.

  • Hyperlink to doc file slow opening

    - by mserioli
    I've two excel file with inside some link to .doc and .pdf file. Both excel files and linked files are on a network shared folder. The first excel file is an .xls, the second an .xlsm. While opening link to .pdf file is very fast (the file is open in few seconds) it take a long time to open .doc files (about 40 secs.). I have searched on internet but found no solution at the moment. I have this problem with both excel 2007 and 2010. Does anyone know how to solve this problem? Thanks a lot Marco

  • Throttling apache downloads selectively

    - by Synchro
    I have a linux box running Debian Sarge (old I know) and apache 2.0.54. It serves two kinds of files - regular web pages and small images, and a lot of large podcast mp3s. The podcast downloads swamp the connection and make the rest of the site unresponsive, so I'm looking to throttle the data transfer rate (not the request rate) of just the podcasts. I've set up haproxy using this technique which does what it says it will, but solves a different problem - even only 5 simultaneous podcast downloads is enough to saturate the link. In a perfect world, haproxy would support per-connection throttling, but it doesn't. So far I've looked at mod_bw (won't compile for me, seems unsupported), mod_cband (unsupported, widely reported as problematic) and iptables using tc. The iptables approach would allow me to throttle things, but would not be at all selective, slowing down everything on the server, not just the podcasts, so would just move the bottleneck without changing overall behaviour. Ideas?

  • Looking for MRP software

    - by Samuel
    I am looking for MRP software. All the stuff I have found so far looks like it's from the 90's and has that very old person business feel. I want something fresh and new. I would prefer an open source, web based solution. PHP/MySQL would be best but not required. I couldn't find anything that was web based that didn't make me want to cry. Superuser doesn't have a lot of eye candy but it still looks great. I am the web developer at my company so if I don't find anything I will be making it my self (well, try to at least).

  • How does datomic handle "corrections"?

    - by blueberryfields
    tl;dr Rich Hickey describes datomic as a system which implicitly deals with timestamps associated with data storage from my experience, data is often imperfectly stored in systems, and on many occasions needs to retroactively be corrected (ie, often the question of "was a True on Tuesday at 12:00pm?" will have an incorrect answer stored in the database) This seems like a spot where the abstractions behind datomic might break - do they? If they don't, how does the system handle such corrections? Rich Hickey, in several of his talks, justifies the creation of datomic, and explains its benefits. His work, if I understand correctly, is motivated by core the insight that humans, when speaking about data and facts, implicitly associate some of the related context into their work(a date-time). By pushing the work required to manage the implicit date-time component of context into the database, he's created a system which is both much easier to understand, and much easier to program. This turns out to be relevant to most database programmers in practice - his work saves everyone a lot of time managing complex, hard to produce/debug/fix, time queries. However, especially in large databases, data is often damaged/incorrect (maybe it was not input correctly, maybe it eroded over time, etc...). While most database updates are insertions of new facts, and should indeed be treated that way, a non-trivial subset of the work required to manage time-queries has to do with retroactive updates. I have yet to see any documentation which explains how such corrections, or retroactive updates, are handled by datomic; from my experience, they are a non-trivial (and incredibly difficult to deal with) subset of time-related data manipulation that database programmers are faced with. Does datomic gracefully handle such updates? If so, how?

  • Lost Windows 7 files

    - by Pader
    My intention was to have a dual boot system with Ubuntu and Windows 7. Obviously I did something wrong because although I had a system menu on booting (is it normal to appear DOS-like?) which gave me an option of booting into windows 7, I was unable to do so. Also, when I booted into Ubuntu, my Windows 7 drive was not available. The Windows 7 drive was an internal 1TB drive partitioned into a 200GB (OS) and a second partition making up the remainder. I was still unable to access this Windows 7 drive even after deleting Ubuntu as I kept getting an 'requires an NTFS drive' error, or something similar. I could not even re-install Windows 7 as the disk was not recognised. I did eventually get the drive back by but I cannot for the life of me remember how. I did try to recover my lost W7 data using Ontrack Easy Recovery (which has always been succesfull in the past for post format recovery) but it would not recognise the 1TB although it was now formatted as NTFS. From other posts on this site, I gather that this is considered a 'Windows 7 Site' problem by Linux users. However, I would dearly love to recover some of my lost Windows 7 files. I had resigned myself to a lot of lost personal data but I happened to notice that a 2TB drive I had connected through a USB docking station had been repartitioned. It must have happened when I installed Ubuntu as I can think of no other explanation. I certainly do not remember consciously requiring Ubuntu to do this. The additional two partitions on the 2TB drive, the original Windows

  • Windows Phone 7 and WS-Trust

    - by Your DisplayName here!
    A question that I often hear these days is: “Can I connect a Windows Phone 7 device to my existing enterprise services?”. Well – since most of my services are typically issued token based, this requires support for WS-Trust and WS-Security on the client. Let’s see what’s necessary to write a WP7 client for this scenario. First I converted the Silverlight library that comes with the Identity Training Kit to WP7. Some things are not supported in WP7 WCF (like message inspectors and some client runtime hooks) – but besides that this was a simple copy+paste job. Very nice! Next I used the WSTrustClient to request tokens from my STS: private WSTrustClient GetWSTrustClient() {     var client = new WSTrustClient(         new WSTrustBindingUsernameMixed(),         new EndpointAddress("https://identity.thinktecture.com/…/issue.svc/mixed/username"),         new UsernameCredentials(_txtUserName.Text, _txtPassword.Password));     return client; } private void _btnLogin_Click(object sender, RoutedEventArgs e) {     _client = GetWSTrustClient();       var rst = new RequestSecurityToken(WSTrust13Constants.KeyTypes.Bearer)     {         AppliesTo = new EndpointAddress("https://identity.thinktecture.com/rp/")     };       _client.IssueCompleted += client_IssueCompleted;     _client.IssueAsync(rst); } I then used the returned RSTR to talk to the WCF service. Due to a bug in the combination of the Silverlight library and the WP7 runtime – symmetric key tokens seem to have issues currently. Bearer tokens work fine. So I created the following binding for the WCF endpoint specifically for WP7. <customBinding>   <binding name="mixedNoSessionBearerBinary">     <security authenticationMode="IssuedTokenOverTransport"               messageSecurityVersion="WSSecurity11 WSTrust13 WSSecureConversation13 WSSecurityPolicy12 BasicSecurityProfile10">       <issuedTokenParameters keyType="BearerKey" />     </security>     <binaryMessageEncoding />     <httpsTransport/>   </binding> </customBinding> The binary encoding is not necessary, but will speed things up a little for mobile devices. I then call the service with the following code: private void _btnCallService_Click(object sender, RoutedEventArgs e) {     var binding = new CustomBinding(         new BinaryMessageEncodingBindingElement(),         new HttpsTransportBindingElement());       _proxy = new StarterServiceContractClient(         binding,         new EndpointAddress("…"));     using (var scope = new OperationContextScope(_proxy.InnerChannel))     {         OperationContext.Current.OutgoingMessageHeaders.Add(new IssuedTokenHeader(Globals.RSTR));         _proxy.GetClaimsAsync();     } } works. download

  • A complete tool for auditing and archiving emails would be helpful for the community?

    - by Renato Todorov
    Please, don't treat this like a discussion question, I'm looking for direct answers: Yes / No, because... I work on a financial company and I'm needing a tool for email archiving and auditing. The compliance sector is asking for it and I have to provide it. I've searched and found two solutions: MailStore (commercial, Windows only) and Enkive (open source, very poor UI and lack of features). I'm using Postfix as MTA and Courier for IMAP/POP access. I'm almost deciding to write it myself, I have the knowledge needed, but I'm wondering right now if it's worth to put (a lot) more hours to make it open source and user friendly. So my question is, have you ever had the same need? Would this be a helpful solution? Is there any other good tool that I haven't found? Thank you!

  • Dual Boot menu with Ubuntu and Windows 8 not showing up

    - by user180630
    I know a lot of posts have been written, and I had read most of them when I encountered the problem. None of them solved the problem. I have successfully installed Ubuntu 12.04 on top of Windows 8. Now my PC simply boots into Windows 8. If I press 'Esc' at start of BIOS, and then F9,the GRUB shows up and Ubuntu is listed at the top of the several options to boot from. I did run Boot-Repair once I logged into Ubuntu explicitly from GRUB as mentioned above. I did all said by Stormvirux in this link but was still unsuccessful. The debug info is listed here. Something which confuses me is the message which Boot-Repair stated after it did its job. You can now reboot your computer. Please do not forget to make your BIOS boot on sda (8004MB) disk! The boot files of [The OS now in use - Ubuntu 12.04.2 LTS] are far from the start of the disk. Your BIOS may not detect them. You may want to retry after creating a /boot partition (EXT4, 200MB, start of the disk). This can be performed via tools such as gParted. Then select this partition via the [Separate /boot partition:] option of [Boot Repair]. (https://help.ubuntu.com/community/BootPartition) I don't know why it says it is far from the start of the disk as I see it first in the GRUB menu which comes up at startup. One more input, when I try to place the GRUB in sda, Boot-Repair does not progress giving me the following error: GPT detected. Please create a BIOS-Boot partition (>1MB, unformatted filesystem, bios_grub flag). This can be performed via tools such as Gparted. Then try again. Alternatively, you can retry after activating the [Separate /boot/efi partition:] option. I had to select Separate /boot/efi partition: sdb2

  • How do I get around restrictive email policies by ISP?

    - by Peter Turner
    Apparently we've been restricted (though packet filtering) to some arbitrarily small and untenable number of emails a day by some bankrupt ISP (and they say that's how it's always been chortle). We've been using our own mail server for the last 15 years, and only recently they've been giving us guff. Is there a way for a legitimate business to email their clients, who really want to receive these emails, by bypassing the ISP? The way we've been doing it is by breaking up into 20 or 30 emails, but that gets complicated and requires a lot of manual labor by the receptionist, and unless she's really careful we wind up emailing lots of people twice. So what are my options (Hosted Email, Lithuanian Proxy Server, Different ISP, not writing awful PHP that sends out zillions of emails and gets us blacklisted)?

  • How to suggest changes as a recently-hired employee ?

    - by ereOn
    Hi, I was recently hired in a big company (thousands of people, to give an idea of the size). They said they hired me because of my rigor and because I was, despite my youngness (i'm 25), experienced as a C/C++ programer. Now that I'm in, I can see that the whole system is old and often uses obsolete technologies. There is no naming convention (files, functions, variables, ...), they don't use Version Control, don't use exceptions or polymorphism and it seems like almost everybody lost his passion (some of them are only 30 years old). I'd like to suggest somes changes but i don't want to be "the new guy that wants to change everything just because he doesn't want to fit in". I tried to "fit in", but actually, It takes me one week to do what I would do in one afternoon, just because of the poor tools we're forced to use. A lot my collegues never look at the new "things" and techniques that people use nowadays. It's like they just given up. The situation is really frustrating. Have you ever been in a similar situation and, if so, what advices would you give me ? Is there a subtle way of changing things without becoming the black sheep here ? Or should I just give up my passion and energy as well ? Thank you. Updates Just in case (if anyone cares): following your precious advices I was able to suggest changes and am now in charge of the team that must create and deploy Subversion :D Thanks to all of you !

  • Apache - The name

    - by Joshua Enfield
    I am working on a migration to a newer virtualized server. The old one has Apache 2.2.4 according to the old servers phpinfo(). The new one with the most up to date has 2.2.3. How can this be assuming no trickery is involved? The old one is years old. A lot of the guides I reference use apache2 in folders names and many of the conventions. The newest version of things, as I understand it is called httpd. Did apache change the name from what it originally was? (i.e. break the web server component into its own project called httpd, I realize the original daemon was probably still called httpd)

  • OWA no longer accessing 1 backend exchange server

    - by Morchuboo
    We have IIS hosting OWA that is the web frontend to 3 backend exchange servers. Yesterday we got a lot of event 9791 warnings: "Cleanup of the DeliveredTo table for database 'Second Storage Group\Mailbox Store EUROPE 2' was pre-empted because the database engine's version store was growing too large. 0 entries were purged. At this point the server was crawling. Our Mail admin is currently away and not contactable so we rebooted the server. Everything seems ok when reading mail from outlook and evolution-mapi clients but OWA and active-sync connections cannot access. When logging into OWA, users whos mailboxes are not on this backend server are fine but users on this server can log into the OWA frontend but once submitting their credentials the page returns a 503 service unavailable error. We have since rebstarted the affected exchange server and the IIS server as well as iisreset /noforce but problem persists. Can anyone suggest what we should look at...

  • Will an online degree get you a job that requires "CS or equivalent 4-year degree"? [on hold]

    - by qel
    I'm a nerdy slacker type who didn't get my life together till I was 30. I've had a real job for a couple years doing C#/SQL. I've gotten several raises, but I'm making less than most developers, and the atmosphere is ... not positive. Looking for a new job, I think my applications get thrown out because I don't have a degree. And I want to finish a Bachelor's just to feel like less of a loser. I have a lot of college credits from 1996-2003 and a low GPA, so I don't know if that's worth much. An online degree looks like a good option, but I just don't know what I should be looking at for online schools because they all look like fake degrees. If they had programs equivalent to a real Comp Sci degree, I don't think they would have weird sounding names like they do. University of Phoenix has a B.S./Information Technology-Software Engineering. DeVry has a B.S./Computer Engineering Technology program. But that's not CS, and most other things I see have even more fake-sounding names. Are these useless degrees? Some people say DeVry and UoP are acceptable, some people say they're a joke. I have enough experience now, though, that maybe all I'm missing is being able to check the box that I have a 4-year degree. Harvard Extension seems like a real degree, even if it isn't a real Harvard degree, but I'd have to live there at least 3 months, which kinda defeats the purpose of an online degree fitting around work.

  • Block site on a PC logged into a domain and using a proxy

    - by Rauf
    I read lot of posts related with blocking sites. Most of the posts says to edit hosts file. I know it is a good method. But this one is not working for me. Can you guess what is the issue by analyzing the following details, My PC is joined to a domain and using proxy settings, and the logged in user having administrator privileges. After reading some answers, I did the following Changed the hosts file to have # 38.25.63.10 x.acme.com # x client host 127.0.0.1 localhost 127.0.0.1 www.facebook.com Added no proxy for facebook, Still, it is not working.

  • Windows Azure AppFabric SDK - June CTP - Download issues

    - by Charles Young
    Microsoft has announced availability of the June CTP for Windows Azure AppFabric. See http://blogs.msdn.com/b/appfabric/archive/2011/06/20/announcing-the-windows-azure-appfabric-june-ctp.aspx. This is an exciting release and provides greater insight into where the AppFabric team is heading in terms of developer and management tooling. Microsoft is offering space in the cloud to experiment with the CTP, but this is limited, so register early to get a namespace! You can download the SDK for the June CTP. However, we ran into a lot of trouble trying to do this today. Whenever we followed the link, we ended up on the page for the May CTP. We found what appeared to be a workaround which we were able to repeat on another box (and which I reported on Connect), but then a few minutes later I couldn't repeat it. Just now, the given link appears to be working every time in IE, but not in Firefox!   Frankly, the behaviour seems random!   It looks like the same URL points to two different pages, and I suspect that which page you end up on is hit and miss. The link to the download page is http://www.microsoft.com/download/en/details.aspx?id=17691. If you end up on the wrong page, try again later and you may get to the right place. Or try googling "Windows Azure AppFabric SDK CTP – June Update" and following a link to this page. For some reason, that sometimes seems to work. Good luck!

  • Windows7 + Dell D830 = frequent blue screens

    I'm using Windows 7 on a Dell laptop (Latitude D380). The laptop used to be incredibly stable on Windows XP, but now I experience frequent blue screens (with a message saying "MEMORY DUMP") when I open a lot of applications concurrently. Is there a way to diagnose the issue and track it down? It could be some incompatible drivers or application. I checked the folder C:\Windows\Minidump and I found some files. THen I tried to open them and they disappeared. Any hints?

  • Which Ubuntu linux kernel tree matches my installed kernel?

    - by Rmano
    Answering a recent question, and before that, trying to see if a patch which is fundamental for my machine had been included in a kernel release, I have found the following problem: How can I match the kernel version I have for my kernel, which is [:~] % uname -a Linux samsung-romano 3.13.0-29-generic #53-Ubuntu SMP Wed Jun 4 21:00:20 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux with the exact kernel source, which I suppose should be stored in http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=summary? In that page there are quite a lot of tags, for example: But none of them correspond to 3.13.0-29 which is my running kernel right now. The mapping should be in https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable, where it is said that the 3.13 Ubuntu kernel is based on 3.13.11 --- I think. But from there to finding the tree I have installed is not straightforward. Notice: I know I can install the kernel source corresponding with my installed kernel. But I do not want to install them; I would like ti have a pointer to the git tree to be able to browse it online (and check for commits, patches, etc.). The best options seems to go to linux3.13-y.review or linux3.13-y.queue, but I am unable to find where this tree are marked for the release - if I understand well the policy, in -review the patches are accumulated for testing, and in -queue accumulated for the next minor release/update --- but I am unable to find the exact release tree. I mean, a tag equivalent to 3.13.0-29 was cut here.

  • rfid programming

    hi guys, I got a gift from a friend, 2 readers for RFID, and some cards (from a Chinese company called daily rfid), the kind of work, because it comes with some demo software written in Delphi, that reads the id of the card (myfare compatible, ISO14443A ) but the problem is that if I try to use the demo to write to them, it doesnt seem to work, it have another demo written in c#, (compiled and executable from /bin/debug, the DL600DemoCSharp.exe), the software opens, but when click on connect, I get this error Unhanded exception.. unable to load DLL 'BasicB.DLL' so I load the dll on windows/system32, but when I try regsvr32 BasicB.dll I get, error the module "BasicB.dll" was loaded but hte entry-point DllRegisterServer was not found. Make sure that "BasicB.dll" is a valid DLL or OCX file and then try again have written to the company but no response, I program in objective C, so I kind of understand c#, but how to make this cards work? - shall I continue with the delphi, and try to write to them with it - or with c# - either way I would have to write the code to read write to them,, or is there any software to work with this modules?? thanks a lot!

  • How to know if my nginx is in good health?

    - by Howard
    I am running a nginx on EC2 (m1.small) for SSL termination. I am using 2 workers on Ubuntu, with latest nginx (stable), the network throughput is around 2Mbps and system load average is around 2 to 3. I am wondering if this system is in good health for now, e.g. what is the queue length (I know nginx can handle a lot of concurrent request, but I mean before the request is being served, how many of them need to wait before being served) what is the average queue time for a given request to be served. I want to know because if my nginx is cpu bounded (e.g. due to SSL), I will need to upgrade to a faster instance. My current nginx status Active connections: 4076 server accepts handled requests 90664283 90664283 104117012 Reading: 525 Writing: 81 Waiting: 3470

  • servers connected to a poweredge 6248 receive traffic for their 'neighbours'

    - by Hannes
    In the network we have a few vlans but at the moment I was investigating vlan2 which carries the most traffic. When tcpdumping on the eth0.2 interface, I see a lot of packets arriving which are not addressed to, nor coming from the server. I checked this on several servers in the network and they all have the same issues. In short, our switches don't switch the traffic but threat it like they are a hub. Can you tell me what settings on the dell poweredge 6248 should prevent this behaviour?

  • Web development and tips for building a website and the advantages of using HTML 5 in the site

    - by Siddarth
    I am trying to make a website for my college, and the program starts from jan 13 and we get 15 days of time to develop a running site. The best site will become the college site. I am participating, for all these days i used to participate in C and C++ contests and also won a few contests, now i am really into web dev for the last 2 months. I knew HTML long ago recently i brushed up on it and learnt javascript from "javascript and jquery the missing manual"(sorry for not adding the link) and recently bought "PHP and MySQL web development" and I am going on fine with it, but still a lot of pages to cover in that book. After this what do i need to know ajax is one language to concentrate on, what else do i need to do to make this project up and running. Can someone let me know the tricks of this trade and complete information to build a site like this. Right now i am good with javascript HTML and CSS and thats it, what else I am studying HTML5 and CSS3 its pretty fast and neat. The info on site is a college website which includes students profiles where the have to register their info with college id number and pretty much thats it. Think of it as a college site + a social networking site for students, where they can upload there pics and videos pdf books etc.

  • Windows 8 Start Screen: Show programs in order of most frequently used

    - by Johnny W
    For me the Windows 8 Start Screen is just a great bit version of the old Start Menu, but unlike the Start Menu, it doesn't seem to order programs by frequency of use? Consider the following: While I DO use Chrome, Steam, and iTunes a lot. I've never ran Adobe Media Encoder, nor Adobe Extension Manager, nor Acrobat Distiller, or indeed most of the things on that list! Or there a way to change sorting to most frequently clicked on? Or perhaps even create FOLDERS in which to group items (e.g. "Adobe Apps" or "Games" or "Microsoft Office"?). Dragging them one at a time takes an age!
