We are still looking for a space so ping me if you can help host 100 people, but if you want to register you can do it here. also, details about the event are on my twitter account and at the #OpenVolcano10 hashtag on twitter. ...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • Any frameworks or library allow me to run large amount of concurrent jobs schedully?

    - by Yoga
    Are there any high level programming frameworks that allow me to run large amount of concurrent jobs schedully? e.g. I have 100K of urls need to check their uptime every 5 minutes Definitely I can write a program to handle this, but then I need to handle concurrency, queuing, error handling, system throttling, job distribution etc. Will there be a framework that I only focus on a particular job (i.e. the ping task) and the system will take care of the scaling and error handling for me? I am open to any language.

  • Question Virtual Network and NAT set-up

    - by Jay
    Hi Guys! I need some help. I'm completely new to Linux. I'm trying to set up the following scenario: +-----+eth0 +-----+ +---+ | VM2 |-----------| VM1 |---------------| H | +-----+ eth1 +-----+eth0 (NAT) +---+ VM2 - Virtual machine from Virtual Box, using Ubuntu VM1 - Virtual machine from Virtual Box, using Ubuntu: I want this to act as a NAT. H - Host, my Windows Vista The dots were just added since after saving the spaces disappear. So if I ping H from VM2, H would receive a different IP address from VM2. Could you give me a step by step on this? All machines are of course 32 bit. Thanks. Would appreciate the help so much.

  • IIS isn't propagating domain

    - by ErocM
    I called Godaddy and 'verified' my settings for the two ips were correct. ns1.asezo.com = xx.xx.xx.15 ns2.asezo.com = xx.xx.xx.16 then I set the nameserver of asezo.com to the ns1/ns2 above, which Godaddy tech support says is right. When I try to visit my site, it says Oops! Google Chrome could not find asezo.com. When I try to ping the website, it gives me a time out. I have the bindings in IIS for the default website as: http - xx.xx.xx.15 - 80 www.asezo.com and http - xx.xx.xx.15 - 80 asezo.com And I'm still getting nothing. I can go directly to the ip http://xx.xx.xx.15/ and it gives me the IIS default website, I just can't get the url to propagate. What am I doing wrong?

  • What failure can kill a long running IRC client? [closed]

    - by Xeoncross
    I have an IRC bot that I built in PHP using sockets that attempts to run forever and (if disconnected) reconnects again. I have it listening to several channels. Apparently it's fairly resilient, because it can run for several days before the process ends and CRON has to start it up again. However, based on the fact the process ends I'm assuming there are other conditions I'm not accounting for that are causing problems. I have nothing in my error logs giving me a hint. In addition, sometimes the process will continue running - but I notice it's no longer present in any of the channels on the IRC server which makes me think it violated some part of the protocol. I have logic setup to handle: reply to PING's correctly reconnect on disconnect (and reconnect to channels) respond to private messages (so someone doesn't ban it) prevent memory leaks What other failure could be killing my long-running IRC client?

  • Static IP breaks Network connection

    - by Pasquale Tedesco
    I am somewhat new to Linux. I am setting up a Web server and installed Ubuntu server 14.04 on an vSphere ESXi 5.5 host. I am connecting perfectly fine to the internet when using DHCP but when I apply my Static settings I loose the ability to connect to websites. Whats weird is I can Ping google.com but if I try wget gooogl.com it hangs at connecting to google.com (google.com):173.194.43.32:80 and I get "failed: connection refused" But if I am set to DHCP the connection resolves perfectly. Thanks # This file describes the network interfaces available on your system # and how to activate them.

  • Connection timed out when connecting to a website (ubuntu only)

    - by S.C.
    I've been struggling with these problem for months. It happens randomly and it happens on Ubuntu only (12.04). It's about my hosted company website. Some facts: I can ping it I can traceroute it I can dig it I can make a nslookup But whenever I try to open it in Chrome it won't open. I also tried using polipo but got same connection time out issue. I'm connected through a LAN network and I'm experiencing no problem with any other website. Is there a more accurate debugging technique I'm missing other than pinging/tracerouting, etc.?

  • Using apt-get from Canada

    - by Advant Edge
    I am using Ubuntu Server 12.04 LTS, and until yesterday, everything was quite peachy. I have installed several packages (MySQL, apache2) and to my knowledge have those configured correctly. Upon configuration of phpMyAdmin, I found that I was missing the directory path /etc/phpmyadmin, which got me thinking about the install. I am new to Ubuntu, so I guess I missed the message telling me that I did not download phpMyAdmin successfully. Anyway, trying to use apt-get yesterday/today results in "Failed to fetch..." messages, even if just to run sudo apt-get update. Some notable details: ···no GUI, command line only (sudo apt-get gksu fails, go figure) ···can ping 4.2.2.2, so I know the internet is out there (somewhere) ···this is a dedicated computer, using Samba to share files with Windows, which does work ···attempted to edit my /sources.list file, for various American/Canadian mirror, to no effect ···ensured I have correct DNS settings in /etc/networks/interfaces I'm not sure where along the way it happened, but I seem to have lost connections to repositories... :) Any advice (including GO BACK TO WINDOWS) is appreciated.

  • Adding a 'network' USB printer

    - by AndrewK
    I have a HP Deskjet 1050a printer, hence the 'network' in the title. Its a bog standard USB home printer. I have it attached to my router (has a USB port in it). I have got it connected and working to with Win8 PC and also a MacBook Air. Can't seem to get it to add as a printer to my Xubuntu laptop(s). It doesn't get detected automatically (not an actual network printer) and i've tried multiple options to get it working. It seems to add it but when printing a test page its saying the printer isn't connected. Ping works fine so it can see it, just can't add it as a printer. With Win8 I had to create a port with the IP of the printer (192.168.1.253 in this case), is there an Ubuntu alternative to do this?

  • access to site owner not working

    - by Daveo
    I made a website it works for everyone except for the site owner, who cannot access the site. He gets a server could not be found error. I went to his house and the issue occurs for all of his devices (PC, laptop, iPhone using WiFi) when I turn WiFi off the iPhone it works. So I thought it was a problem on his router so I reset is router to default factory settings but it still does not work, I have flushed his DNS cache and his browser cache. But nothing seems to help. He cannot even PING the server using the domain name. However when he uses the IP address he can see the site fine. I looked in cpanel for an blocked IP addresses but cannot see anything. What could be stopping just him from accessing the site via domainname and not the IP address? Site details are: PHP, osCommerce it is hosted by site5 on my reseller account.

  • Unity3D or UDK or OPENGL from scratch?

    - by Legolas
    I am just very confused which I should choose in terms of high end game development. The application that I am designing is pretty simple, requires some 3D, and some effects. I am looking at a game similar to ping pong, but with high textures and graphics. I will just need web services to submit high scores. From my description, you can see that its pretty straight forward and I am confused whether I should use Unity3D or UDK or write the entire application myself with openGL (which will take a lot of time though). If you had faced this dilemma before, and chose for a particular graphics engine, please provide your suggestions and reasons as to why that was better. It would be helpful. Also, how can this affect in terms of investment and revenue ?

  • My Herokuapp is inaccessible from custom domain name

    - by picardo
    I have a Heroku app that is located at myapp.herokuapp.com. I have mapped a domain name to this app, using the A properties. I followed the instructions on Heroku's website to the letter, and it worked for a few days. Now when I try to access the site from the custom domain, it's timing out! On Chrome, I am getting "Oops! Google Chrome could not find that page!" message. I tried pinging the name as well, but I got this error: ping: cannot resolve yourhostname.org: Unknown host The app itself is working and I don't see any error messages from Heroku. Or from new Relic. What's going on here? Also tried running host and this was the error message: ;; connection timed out; no servers could be reached

  • wifi works only after connecting through wire

    - by orustam
    I have fresh installed ubuntu 12.04. it is my first ubuntu installation and i'm a bit confused about the network connection. Wifi shows up and connects(at least it shows that the connection is established), but i can't open any pages, i've tried to ping some sites and it fails either. If i try to connect through a wire it works, what is interesting to me is that after i used my wire connection i can use my wifi properly without a wire pluged in. i think it probably has to do with my settings? I tried to find a solution but can figure it out on my own. My Proxy set to none(have applied it system wide) Please help me if you have any clue:)

  • Ubuntu and WiFi Network

    - by Anonymous
    I have been trying to figure out this problem. I am currently dual-booting Ubuntu with my Windows machine. My Ubuntu would connect to my wireless router but it cannot access any web pages nor ping any hosts. Wired connection works just fine. My Windows OS in the same machine (with the exact same network configuration as my Ubuntu machine) connects and works fine. I don't know why Ubuntu cannot access the Internet. Any ideas?

  • Can't boot - "Waiting for Network Configuration"

    - by user213017
    After an update on 13.10, my PC won't boot Ubuntu any longer. It displays the infamous "Waiting for Network Configuration" message and then hangs. I can go into recovery mode, and choose "Start networking" and then go to a root prompt, and that works fine. Ping works. /etc/network/interfaces contains just the two lines "auto lo" and "iface lo inet loopback". I've double-checked that my network is working, the cable is working (it works on another PC) and the network card seems to indicate a connection. Any suggestions on how to get my PC booted again? Right now I'm limited to a root shell prompt.

  • Nokia porte à nouveau plainte contre Apple et lui reproche la violation de 13 de ses brevets

    Nokia porte à nouveau plainte contre Apple, et lui reproche la violation de 13 de ses brevets Mise à jour du 16.12.2010 par Katleen Le feuilleton juridique Apple vs. Nokia continue. Alors que les deux firmes semblent jouer au ping pong en se renvoyant sans cesse la balle de plainte en plainte, le constructeur finlandais vient d'en remettre une couche. Nokia a en effet rapporté aux tribunaux des violations de brevet de la part de la compagnie de Steve Jobs, pour la quatrième fois. Alors que l'ITC est toujours en train de délibérer avant de rendre ses conclusions sur une affaire similaire entre les deux firmes, une nouvelle plainte vient d'être déposée. Nokia accuse Apple...

  • Internet (HTTP) is not working on Sony Viao

    - by vijay
    I switched my sony viao laptop from XP to ubuntu 10.04 recently. I have it connected through router at home. The internet was working fine with XP. With ubuntu, i am not able to connect to interenet. I am able to update using apt, and i am able to ping too. It seems like there is a DNS issue, when i try to goto sites from firefox, it doesn't work. I tried disabling the ipv6 in firefox config, it doesn't work. My router is on 192.168.2.1 instead of 192.168.1.1 any ideas on what config i might need to change to make this work? or could this be a drive issue?

  • Why hamachi time-outs after 5 minutes or so?

    - by Vik89
    I installed hamachi and hamachi-gui on my girlfriend's pc and on my girlfriend's netbook. After 5 minutes or so (even if I keep using it during that time) it loses the connection, I mean I have to 'go offline' and then 'go online' again for it to see my ip again. If I don't and I ping my IP, it says 'Host unreachable'. If I connect with my Mac from the office the problem doesn't exist, so I wouldn't say it is a problem of my hamachi (server) installation, I'm tempted to say it is a problem of my girlfriend's connection, since it happens from her home, and we haven't tried yet to connect from another home with her setup. What would you say? I followed these instructions http://ubuntuforums.org/showthread.php?t=135036

  • Wireless will not work in fresh ubuntu 12.04 lts installation

    - by Taake Manning
    I did a fresh Ubuntu 12.04 install on my Sony Vaio laptop, which worked perfectly with 10.04. Now my wireless won't work. I have read just about every Q&A on the subject and I have tried different solutions, including the official troubleshooting guides. My laptop is equipped with a Intel 5100 wireless device. Ubuntu recognizes the device and it's status is given as connected in nm-tool. I can ping the gateway, my own IP number and localhost. Rfkill shows no soft or hard blocks. Any ideas? I am just a few hours shy of reinstalling good old 10.04! Taake

  • alx driver not working properly

    - by user292768
    My alx driver seems to be working fine for everything except apt-get. I can navigate to web pages, the ping command works just fine, but whenever I try to do apt-get update or apt-get install it hangs on trying to connect to whatever archive it's trying to pull info from. There's no error message, nothing to imply that it can't connect, it just hangs there and does nothing at all. I've tried re installing alx, upgrading/downgrading my linux kernel, downloading source and building alx from scratch, etc etc but nothing works. Does anybody else have this problem/know how to fix it?

  • Connection make b/w iphone to windows pc-rajay [on hold]

    - by Rajay
    I Need to create connection between ios to windows by using socket programming in ios. I'm trying to to use an application to communicate with Windows via sockets. At the minimum, I'm trying to at least figure out how I can create a connection from the iPhone (maybe using the iPhone to ping the Windows machine?) I'm not really clear on where I need to start. I'm pretty new to iOS development in general, and brand new to socket/network programming. I've tried several tutorials that haven't gotten me far. My goal is: Connect to a server via sockets (the server will be a Windows machine with a service waiting for incoming connections from the iPhone) If possible, I would like to write/build the client piece first, but I have been lost thus far. Hopefully the nice folks in the SO community can lend a hand and point me in the right direction.

  • Ubuntu 12.04 VM goes dead unexpectedly

    - by pyInTheSky
    I'm not a super savvy super user, so I'm not sure what to look for. I have a vm running 12.04. It runs fine, and then just dies (no ping, no ssh). When I log into vmwaresphere, I see the vm still 'UP', but the console gives me a response-less black screen. This lead me to believe that Ubuntu was going into some sort of sleep/hibernate state. I double checked the power settings and found nothing out of the ordinary, so now I'm stuck on how to fix the problem. There are 5-7 (centos-5.8 & 6) machines running on the same server/vm setup with no problems at all. thanks.

  • MATLAB Easter Egg Spy vs Spy

    I heard that MATLAB 2009b or earlier had a fun function. When you typed spy in the console, you would get something like this: http://t2.gstatic.com/images?q=tbn:ANd9GcSHAgKz-y1HyPHcfKvBpYmZ02PWpe3ONMDat8psEr89K0VsP_ft However, now you have an image like this:http://undocumentedmatlab.com/images/spy2.png I'd like it if I could get the code of the original spy vs spy image FYI, there's a code, but has certain errors in it: c = [';@3EA4:aei7]ced.CFHE;4\T*Y,dL0,HOQQMJLJE9PX[[Q.ZF.\JTCA1dd' '-IorRPNMPIE-Y\R8[I8]SUDW2e+' '=4BGC;7imiag2IFOQLID8''XI.]K0"PD@l32UZhP//P988_WC,U+Z^Y\<2' '&lt;82BF>?8jnjbhLJGPRMJE9/YJ/L1#QMC$;;V[iv09QE99,XD.YB,[_]=3a' '9;CG?@9kokc2MKHQSOKF:0ZL0aM2$RNG%AAW\jw9E.FEE-_G8aG.d]_W5+' '?:CDH@A:lpld3NLIRTPLG=1[M1bN3%SOH4BBX]kx:J9LLL8H9bJ/+d_dX6,' '@;DEIAB;mqmePOMJSUQMJ2\N2cO4&TPP@HCY^lyDKEMMN9+I@+S8,+deY7^' '8@EFJBC<4rnfQPNPTVRNKB3]O3dP5''UQQCIDZ_mzEPFNNOE,RA,T9/,++\8_' '9A2G3CD=544gRQPQUWUOLE4^P4"Q6(VRRIJE[n{KQKOOPK-SE.W:F/,,]Z+' ':BDH4DE>655hSRQRVXVPMF5_Q5#R>)eSSJKF\ao0L.L-WUL.VF8XCH001_[,' ';3EI<eo ?766iTSRSWYWQNG6$R6''S?*fTTlLQ]bp1M/P.XVP8[H9]DIDA=]' '?4D3=FP@877jUTSTXZXROK7%S7(TF+gUUmMR^cq:N9Q8YZQ9_IcIJEBd_^' '@5E@GQA98b3VUTUY*YSPL8&T)UI,hVhnNS_dr;PE.9Z[RCaR?+JTFC?e+' '79FA?HRB:9c4WVUVZ+ZWQM=,WG*VJ-"gi4OTes-XH+bK.#hj@PUvftDRMEF,]UH,UB.TYVWX,e\' '9;ECAKTY< ;eWYXWX\:)YSOE.YI,cL/$ikCqV1guE/PFL-^XI-YG/WZWXY1+]' ':AFDBLUZ=jgY[ZYZ-<7[XQG0[K.eN1&"$K2u:iyO9.PN9-_K8aJ9_]]82[' '?CEFDNW\?khZ[Z[==8\YRH1\M/!O2''#%m31Bw0PE/QXE8+R9bS;da^]93\' '@2FGEOX]ali[][9(ZSL2]N0"P3($&n;2Cx1QN9--L9,SA+T< +d_:4,' 'A3GHFPY^bmj\^]\]??:)[TM3^O1%Q4)%''oA:D0:0OE.8ME-TE,XB,+da;5[' '643IGQZ_cnk]_^]^@@;5\UN4_P2&R6*&(3B;E1<1PN99NL8WF.^C/,a+bY6,' '7:F3HR[dol^_^AA<6]VO5Q3''S>+'');CBF:=:QOEEOO9_G8aH6/d,cZ[Y' '8;G4IS\aep4_a-BD=7''XP6aR4(T?,(5@DCHCC;RPFLPPDH9bJ70+0d\\Z' '9BH>JT^bf45ba.CE@8(YQ7#S5)UD-)?AEDIDDD/QKMVQJ+S?cSDF,1e]a,' ':C3?K4_cg5[acbaADFA92ZR8$T6*VE.*@JFEJEEE0.NNWTK,U@+TEG0?+_bX' ';2D@L9dh6\bdcbBEGD:3[S=)U7+cK/+CKGFLIKI9/OWZUL-VA,WIHB@,`cY']; i = double(c(:)-32); j = cumsum(diff([0; i])< =0) + 1; S = sparse(i,j,1)'; spy(S)
