  • Why was Scala not implemented with C or C++

    - by jpartogi
    Does anybody know why was Scala implemented in Java and .NET instead of C or C++? Most languages are implemented with Cor C++ [i.e Erlang, Python, PHP, Ruby, Perl]. What are the advantages for Scala implemented in Java and .NET other than giving access to Java and .NET libraries? UPDATE Woudln't Scala gain more benefit if it is implemented in C because it can be tuned better rather than relying on JVM?

  • How to manage own bots at the server?

    - by Nikolay Kuznetsov
    There is a game server and people can play in game rooms of 2, 3 or 4. When a client connects to server he can send a request specifying a number of people or range he wants to play with. One of this value is valid: {2-4, 2-3, 3-4, 2, 3, 4} So the server maintains 3 separate queues for game room with 2, 3 and 4 people. So we can denote queues as #2, #3 and #4. It work the following way. If a client sends request, 3-4, then two separate request are added to queues #3 and #4. If queue #3 now have 3 requests from different people then game room with 3 players is created, and all other requests from those players are removed from all queues. Right now not many people are online simultaneously, so they apply for a game wait for some time and quit because game does not start in a reasonable time. That's a simple bot for beginning has been developed. So there is a need to patch server code to run a bot, if some one requests a game, but humans are not online. Input: request from human {2-4, 2-3, 3-4, 2, 3, 4} Output: number of bots to run and time to wait for each before connecting, depending on queues state. The problem is that I don't know how to manage bots properly at the server? Example: #3 has 1 request and #4 has 1 request Request from user is {3,4} then server can add one bot to play game with 3 people or two bots to play game of 4. Example: #3 has 1 request and #4 has 2 requests Request from user is {3,4} then in each case just one bot is needed so game with 4 players is more preferrable.

  • Iphone/Android app – chatroom development – what framework & hosting needs?

    - by MikaelW
    I have some experience regarding IPhone and Android development but I am now struggling to solve a new class of problem: apps that involve a client/server chatroom feature. That is, an app when people can exchange text over the internet, and without having the app to constantly “pull” content from the server. So that problem can’t be solved with a normal php/mysql website, there must be some kind of application running on a server that is able to send message from the server to the phone, rather than having the phone to check for new messages every 10 seconds… So I’m looking for ways to solve the different problems here: What framework should I use on the two sides (phone / server)? It should be some kind of library that doesn’t prevent me to write paid apps. It should also be possible to have the same server for the Iphone and android version of the app. What server / hosting solution do I need with what sort of features, I just have no experience regarding server application that can handle and initiate multiple connections and are hosted on hardware that is always online I tried to find resources online but couldn’t so far, either the libraries had the wrong kind of license/language or I just didn’t understand… Sometimes there were nice tutorial but for different needs such as peer2peer chat over local network… Same with the server and the hosting problem, not sure where to start really, I’m calling for help and I promise I will complete this page with notes about the experience I will get :-) Obviously the ideal would be to find a tutorial I missed that include client code, server code and a free scalable server… That being said, If I see something as good, it probably means that I have eaten the wrong kind of mushroom again… So, failing that, any pointer which might help me toward that quest, would be greatly appreciated. Thanks in advance. Mikael

  • What would be the level of effort required to implement a screencapture command on a PS3 game?

    - by Sean Scott
    Looking to see what the level of effort is for implementing a screen capture command into PS3 game by a mid-level PS3 game developer. Bonus for a description of what is involved in the process... EDIT Not sure how to get back my question since it was the first but let me clarify some things. @Nate Bross, nope I am not the actor although i've fielded calls for him on occasion @coderanger my intent was to try and speak to other PS3 developers, however coming from a web development no one in my social circle close or extended develops on the PS3. Additionally i'm interested in hearing the effort required in terms of hours so that this information can be passed on to a client. A client who has a game on the PS3 using the unreal engine. Convo with devs sometimes go something like "can you implement feature a" which gets a response "this will take us 8 weeks and an army". Trying to be educated before the ask. I hope that helps If anyone here is a PS3 game dev and would like to respond off site so as not to break NDA that would be awesome. @Roger it would be from within the game, something that users can use. Something akin to the iphone screencap utility. No need to get fancier than that.

    Dhcpd running on Linux gets a dhcp request over dhcrelay which is running on other remote machine.

However reply does not go to the requesting dhcrelay external IP(192.168.0.81). Instead, it goes to the internal interface IP of machine running dhcrelay. And I think because of this remote machine running dhcrelay or the dhcrealy itself discarding packet.

HOWEVER, I have deleted route on dhcpd server to reach 172.16.17.x subnet. It again tries to send reply to 172.16.17.81.

Because, it is not much meaningful to add routes to subnet we distribute IP for. Internet - dhcpd - 192.168.0.1 - SOMENET - 192.168.0.81 - dhcrelay - 172.16.17.0/24 192.168.0.1 has no route for 172.16.17.0 and has no interface directly attached to that net.

  • when to use squid on server side?

    - by ajsie
    so i have set up apache serving my php pages. i read about squid but don't understand why/how i should use it to speed up my web server. from what i've learned squid is located in same network (or another) and caches content requested by the web browsers, and then when another web browser wants a same page, squid returns that page cached locally, so it never sends a request to the apache server (faster response time for the client, and reduced load for the server). so it seems that squid is for the client side (web browser), and has nothing to do with the server side (apache). but then some people tell others how they have speeded up apache using squid. so im confused. could squid be used on the server side too? and how will it work?

  • JMX Monitoring of GlassFish Servers

    - by tjquinn
    Did you ever wonder what this message in your GlassFish server.log file means? JMXStartupService has started JMXConnector on JMXService URL service:jmx:rmi://192.168.2.102:8686/jndi/rmi://192.168.2.102:8686/jmxrmi It means you can monitor any GlassFish server process, remotely or locally, using any standard Java Management Extensions (JMX) client.  Examples: jconsole or jvisualvm.   Copy the part of the log message that starts with "service:" into the Add JMX Connection dialog of jvisualvm:  or into the New Connection dialog of jconsole: (The full string is truncated in the on-screen display, but if you copied from the server.log and pasted into the form it should all be there.) The examples above are for a DAS, and your host will probably be different.   The server.log files for other GlassFish servers (instances) will have similar log entries giving the JMX connection string to use for those processes.  Look for the host and/or port to be different. Note a few things about security: Here we've assumed you are using the default admin username and password.  If you are not, just enter a valid admin username and password for your installation.  Once connected, you have normal access to all the JVM statistics and controls. You can use JMX clients that support MBeans to view the GlassFish configuration.  When you connect to the DAS, you can also change that configuration, but you can only view configuration when you connect to an instance. To use a JMX client on one system to connect to a GlassFish server running on another system, you need to enable secure admin if you have not already done so: asadmin change-admin-password (respond to the prompts) asadmin enable-secure-admin asadmin restart-domain (as prompted in the output from enable-secure-admin)

  • Overcrowded Windows XP Folders

    - by BlairHippo
    I know that, technically, an individual Windows XP directory can hold an immense number of files (over 4.29 billion, according to a quick Google search). However, is there a practical ceiling where too many files in one directory starts having an impact on reads to those files? If so, what factors would exacerbate or help the issue? I ask because my employer has several hundred XP machines in the field at client sites, and the performance on some of the older ones is getting "sludgy." The machines download and display client-defined images, and my supervisor and I suspect that our slacktastic approach to cache management could be to blame. (Some of the directories have tens of thousands of images in them.) I'm trying to gather evidence to support or contest the theory before spending time on a coding fix.

  • getUserPrincipal() in JCIFS / Lan-Manager authentitation level setting in Windows 2k8

    - by Chris
    I have to find out in which exact format JCIFS stores the user principal in the "getUserPrincipal()" property. Therefor i created a test Environment like this: Windows Server 2008 Domain Controller Domain named "MYDOMAIN" Many Testusers in Active Directory Tomcat Application Server with my Web Application (which simply reads the user Principal and displays its values). The user should be logged in to the web-application with SSO therefor i need the format that jcifs is using to store the user. (For example user@MYDOMAIN or MYDOMAIN\user...) I tested the Authentication with other SSO frameworks with Kerberos Method and it works as expected. I'm now trying to use SSO through the NTLMHttpFilter of JCIFS. When i try to login i get the following error message: jcifs.smb.SmbException: The parameter is incorrect. jcifs.smb.SmbTransport.checkStatus(SmbTransport.java:541) jcifs.smb.SmbTransport.send(SmbTransport.java:641) jcifs.smb.SmbSession.sessionSetup(SmbSession.java:322) jcifs.smb.SmbSession.send(SmbSession.java:224) jcifs.smb.SmbTree.treeConnect(SmbTree.java:176) jcifs.smb.SmbSession.logon(SmbSession.java:153) jcifs.smb.SmbSession.logon(SmbSession.java:146) jcifs.http.NtlmHttpFilter.negotiate(NtlmHttpFilter.java:189) jcifs.http.NtlmHttpFilter.doFilter(NtlmHttpFilter.java:121) Regarding to the documentation i'm using to configure this, this is a know issue with the Group policy. It is stated there, that i have to change the Group policy "Networkaccess: lan-manager authentication level" to respond to NTLMv1 request. I have done this, but it's still not working. So what i also have to configure is the same policy on the client computer. I have to change the policy, so that the client computer sends NTLMv1. But it is always sending NTLMv2 tokens. The problem now is that i'm somehow not able to change this setting. (I already was before) because the dropdown box to choose the authentication method is "greyed out". edit: just to make this clear, this dialog is on the client-side in the "local-security policies" As you can see from this screenshot, the chosen method is "Only send NTLMv2 responses" which is the wrong setting and i'm pretty sure that this is causing the error above. My question is now, why can't i change this setting? Why is it greyd out?

  • firehol (firewall) with bridge: how to filter

    - by Leon
    I have two interfaces: eth0 (public address) and lxcbr0 with 10.0.3.1. I have a LXC guest running with ip 10.0.3.10 This is my firehol config: version 5 trusted_ips=`/usr/local/bin/strip_comments /etc/firehol/trusted_ips` trusted_servers=`/usr/local/bin/strip_comments /etc/firehol/trusted_servers` blacklist full `/usr/local/bin/strip_comments /etc/firehol/blacklist` interface lxcbr0 virtual policy return server "dhcp dns" accept router virtual2internet inface lxcbr0 outface eth0 masquerade route all accept interface any world protection strong #Outgoing these protocols are allowed to everywhere client "smtp pop3 dns ntp mysql icmp" accept #These (incoming) services are available to everyone server "http https smtp ftp imap imaps pop3 pop3s passiveftp" accept #Outgoing, these protocols are only allowed to known servers client "http https webcache ftp ssh pyzor razor" accept dst "${trusted_servers}" On my host I can connect only to "trusted servers" on port 80. In my guest I can connect to port 80 on every host. I assumed that firehol would block that. Is there something I can add/change so that my guest(s) inherit the rules of the eth0 interface?

  • Running a bash script from an HTML link or button

    - by Andrew
    I have a webserver that's hosting lots of images. I want the client to be able to press a button or a link, which will run a bash script, which will create a video based on all these pictures. The script I'm trying to run is this: #!/bin/bash # cd to the directory cd /var/www/gallery # use ffmpeg to make video ffmpeg -pattern_type glob -i 'img-*jpg' -r 1 video.mp4 # Take the first file in the directory and name it video.mp4.jpg (for thumbnail) cp `ls | sort -n | head -1` video.mp4.jpg The script is located on the server. So when the client clicks the link or button, the script will run, and the video is created. I've tried both solutions listed here but I can't seem to get it to work. I have php installed on my server.

  • Java Desktop Application For Network users

    - by Motasem Abu Aker
    I'm developing a desktop application using Java. My application will run in a network environment where multiple users will access the same database through the application. There will be basic CRUD opreations (Insert, Update, Delete, & select), which means there will be chances of deadlock, or two users trying to update the same record at same time. I'm using the following Java Swing for Clients (MVC). MySQL Server for database (InnODB). Java Web start. Now, MySQL is centralized on the network, and all of the clients connect to it. The Application for ERP Purpose. I searched the internet to find a very good solution to ensure data integrity & to make sure that when updating one record from one client, other clients are aware of it. I read about Socket-server-client & RESTful web services. I don't want to go web application & don't want to use any extra libraries. So how can I handle this scenario: If User A updates a record: Is there a way to update User B's screen with the new value? If user A starts updating a record, how can I prevent other users from attempting to update the same record?

  • How to configure remote access to multiple subnets behind a SonicWALL NSA 2400

    - by Kyle Noland
    I have a client that uses a SonicWALL NSA 2400 as their firewall. I need to setup a second LAN subnet for a handful of PC. Management has decided that there should be a second subnet even though intend to allow access across the two subnets - I know... I'm having trouble getting communication across the 2 subnets. I can ping each gateway, but I cannot ping or seem to route traffic fron subnet A to subnet B. Here is my current setup: X0 Interface: LAN zone with IP addres 192.168.1.1 X1 Interface: WAN zone with WAN IP address X2 Interface: LAN zone with IP address 192.168.75.1 I have configured ARP and routes for the secondar subnet (X2) according to this SonicWALL KB article: http://www.sonicwall.com/downloads/supporting_multiple_firewalled_subnets_on_sonicos_enhanced.pdf using "Example 1". At this point I don't minding if I have to throw the SonicWALL GVC software VPN client into the mix to make it work. It feel like I have an Access Rule issue, but for testing I made LAN LAN, WAN LAN and VPN LAN rules wide open with the same results.

  • Passenger 2.2.4, nginx 0.7.61 and SSL

    - by boompa
    Has anyone had any luck configuring Passenger and nginx with SSL? I've spent hours trying to get this configuration working as I'd like, using what few resources there are out there on the net, and I can't get any of the supposedly forwarded headers to show up in the Rails controller. For example, with a conf file of the following (and multiple variations thereof): server { listen 3000; server_name .example.com; root /Users/website/public; passenger_enabled on; rails_env development; } server { listen 3443; root /Users/website/public; rails_env development; passenger_enabled on; ssl on; #ssl_verify_client on; ssl_certificate /Users/website/ssl/server.crt; ssl_certificate_key /Users/website/ssl/server.key; #ssl_client_certificate /Users/website/ssl/CA.crt; ssl_session_timeout 5m; ssl_protocols SSLv3 TLSv1; ssl_ciphers ALL:!ADH:RC4+RSA:+HIGH:+MEDIUM:-LOW:-SSLv2:-EXP; proxy_set_header Host $http_host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X_FORWARDED_PROTO https; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; #proxy_set_header X-SSL-Subject $ssl_client_s_dn; #proxy_set_header X-SSL-Issuer $ssl_client_i_dn; proxy_redirect off; proxy_max_temp_file_size 0; } and Rails code in the controller like this: request.headers.each { |k, v| RAILS_DEFAULT_LOGGER.error "Header #{k} Val #{v}" } other headers appear, but not those set in nginx, e.g.: Header rack.multithread Val false Header REQUEST_URI Val /login/new Header REMOTE_PORT Val 64021 Header rack.multiprocess Val true Header PASSENGER_USE_GLOBAL_QUEUE Val false Header PASSENGER_APP_TYPE Val rails Header SCGI Val 1 Header SERVER_PORT Val 3443 Header HTTP_ACCEPT_CHARSET Val ISO-8859-1,utf-8;q=0.7,*;q=0.7 Header rack.request.query_hash Val Header DOCUMENT_ROOT Val /Users/website/public I've even gone so far as to modify Passenger's abstract_request_handler's main_loop method, i.e., headers, input = parse_request(client) if headers if headers[REQUEST_METHOD] == PING process_ping(headers, input, client) else headers.each { |h,v| log.unknown "abstract_request_handler: #{h} = #{v}" } process_request(headers, input, client) end end only to find that the supposedly added headers do not exist there either: abstract_request_handler: HTTP_KEEP_ALIVE = 300 abstract_request_handler: HTTP_USER_AGENT = Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9.1) Gecko/20090624 Firefox/3.5 abstract_request_handler: PASSENGER_SPAWN_METHOD = smart-lv2 abstract_request_handler: CONTENT_LENGTH = 0 abstract_request_handler: HTTP_IF_NONE_MATCH = "b6e8b9afbc1110ee3bf0c87e119252ad" abstract_request_handler: HTTP_ACCEPT_LANGUAGE = en-us,en;q=0.5 abstract_request_handler: SERVER_PROTOCOL = HTTP/1.1 abstract_request_handler: HTTPS = on abstract_request_handler: REMOTE_ADDR = 127.0.0.1 abstract_request_handler: SERVER_SOFTWARE = nginx/0.7.61 abstract_request_handler: SERVER_ADDR = 127.0.0.1 abstract_request_handler: SCRIPT_NAME = abstract_request_handler: PASSENGER_ENVIRONMENT = development abstract_request_handler: REMOTE_PORT = 64021 abstract_request_handler: REQUEST_URI = /login/new abstract_request_handler: HTTP_ACCEPT_CHARSET = ISO-8859-1,utf-8;q=0.7,*;q=0.7 abstract_request_handler: SERVER_PORT = 3443 abstract_request_handler: SCGI = 1 abstract_request_handler: PASSENGER_APP_TYPE = rails abstract_request_handler: PASSENGER_USE_GLOBAL_QUEUE = false I'm tired of banging my head against the wall, so I'd truly appreciate any help I can get!

  • How to selectively route network traffic through VPN on Mac OSX Leopard?

    - by newtonapple
    I don't want to send all my network traffic down to VPN when I'm connected to my company's network (via VPN) from home. For example, when I'm working from home, I would like to be able to backup my all files to the Time Capsule at home and still be able to access the company's internal network. I'm using Leopard's built-in VPN client. I've tried unchecking "Send all traffic over VPN connection." If I do that I will lose access to my company's internal websites be it via curl or the web browser (though internal IPs are still reachable). It'd be ideal if I can selectively choose a set of IPs or domains to be routed through VPN and keep the rest on my own network. Is this achievable with Leopard's built-in VPN client? If you have any software recommendations, I'd like to hear them as well.

  • Why use FQDN as DNS-server option in DHCP?

    - by Filip Haglund
    I've seen multiple default configurations of DHCP-servers with a FQDN set as the DNS-server option. Doesn't this imply a catch-22, or the need for that DNS-server to be in the hosts file of every single client? example from dhcp3-server in debian 6: option domain-name-servers ns1.internal.example.org; I can see how using a dns name is convenient because it's only an A-record to change, and they can be load balanced if wanted, but I don't see how the client is going to resolve the name. Why are people using FQDN's as DNS-server addresses in DHCP?

  • Connection to mysql server in SYN_SENT

    - by Sunil
    We are facing a strange problem from last few days between our application server and database server(Mysql): connection to database server from application server hangs in SYN_SENT state and after that we are not able to make any connection to database server on mysql port(3306). When we checked the netstat output on database server its in SYN_RECV state. What I can figure out is mysql server is receiving the SYN request and responding also and its not reaching to the client hence SYN_RECV at server side and SYN_SENT at client side. I think SYN_SENT state should go after some time and because of this other db connection attempts to same server should not hang. Does anybody have any idea how can we resolve this issue? Out setup details : Application server: RHEL 5.4, kernel-release = 2.6.18-164.el5, x86_64 Database server: Mysql Version : 5.1.49 RHEL 5.4, kernel-release = 2.6.18-164.el5, x86_64

  • Hidden DNS master only sending notify to one slave

    - by Rob
    My hidden DNS master is only sending notifies to one of the name servers for a zone I have 3 named servers ns0,ns1 & ns2 all running bind 9.7.3.dfsg-1ubuntu4.1. When an update is processed the master (ns0) seems to behave normally. ns0 (192.168.2.50) zone domain.org/IN: sending notifies (serial 2012060703) client 192.168.2.52#42892: transfer of 'domain.org/IN': AXFR-style IXFR started: TSIG rndc-key client 192.168.2.52#42892: transfer of 'domain.org/IN': AXFR-style IXFR ended ns2 (192.168.2.52) client 192.168.2.50#3762: received notify for zone 'domain.org': TSIG 'rndc-key' zone domain.org/IN: Transfer started. transfer of 'domain.org/IN' from 192.168.2.50#53: connected using 192.168.2.52#55747 zone domain.org/IN: transferred serial 2012060704: TSIG 'rndc-key' transfer of 'domain.org/IN' from 192.168.2.50#53: Transfer completed: 1 messages, 34 records, 1028 bytes, 0.001 secs (1028000 bytes/sec) Nothing happens on ns1. I've turned up the logging level but there's no information in syslog about the actual name servers bind has sent notifications to so I guess this is something it doesn't log. I've also tried watching tcpdump, it never makes any attempt to notify ns1 only ns2 192.168.2.50.56278 > 192.168.2.52.53: [udp sum ok] 56418 notify [b2&3=0x2400] [1a] [1au] ?

I was under the impression bind would automatically send notifies to all NS records on a zone, maybe it's bugged?

  • Streaming media from linux server - low footprint is crucial

    - by Mike Haye
    I recently pre-ordered the Raspberry Pi. http://www.raspberrypi.org/faqs For those of you who don't know it, it's a machine with 256 mb ram and a 700 MHz processor for $35. I plan to run linux on an SD card on this machine and have it act as both a htpc, VPN and media server. In regard to the media server part, I need to find some linux software that has a small footprint, but allows me to stream media to other devices connected to the internet (preferably without having to install any additional software on the client machines) Also, I would love if the video could be compressed, so the data usage wouldn't be so big for the client machine (e.g. when I'm using my data plan on my smartphone ;) ) Thanks in advance for any answers :) Mike.

  • Replicate GAE Datastore On A Server LAN in Java

    - by Franz Noel
    There may be instances wherein one Company Client may not have internet connection on their vicinity. Either their Internet Service Provider currently experience a down time or there are some other problems involving the network, but not their LAN. GAE seems to be needing a connection at all times in the internet. I only need GAE Datastore. I'm thinking about a different application. Creating a Java Swing Client, for instance, and connecting to the Office Server via HRD of GAE Datastore. When I tried to check on the solutions for Java, it does not say anything about uploading all data and I do not need the App. I just need the GAE Datastore. In Java GAE, only indexes can be able to be manipulated. So, is there any tricks/ideas that you can use HRD with GAE Datastore on Java with an Internal Office Server combined? This way, it may provide service even during network down times. (Can somebody create me a tag of gae-datastore, please.)

  • Exchange 2003 ActiveSync fine but GAL lookups not working

    - by Daniel Lucas
    We have Exchange 2003 SP2 and use ActiveSync for our mobile devices (iOS and sever Android versions). Everything works except for GAL lookups and we've confirmed that the devices and client versions we are trying it on are supposed to support it. The symptom is different depending on the client, but there is never an error. In a nutshell, lookups return no results. This was working previously and we aren't sure what has changed. Are there logs in Exchange or IIS that will allow me to see GAL lookup transactions? Could it be a GAL permissions issue? (No issues with GAL in Outlook) Could it have been caused by upgrading our DCs to 2008 and increasing the forest/domain functional levels?
