  • (How) Can I approximate a "dynamic" index (key extractor) for Boost MultiIndex?

    - by Sarah
    I have a MultiIndex container of boost::shared_ptrs to members of class Host. These members contain private arrays bool infections[NUM_SEROTYPES] revealing Hosts' infection statuses with respect to each of 1,...,NUM_SEROTYPES serotypes. I want to be able to determine at any time in the simulation the number of people infected with a given serotype, but I'm not sure how: Ideally, Boost MultiIndex would allow me to sort, for example, by Host::isInfected( int s ), where s is the serotype of interest. From what I understand, MultiIndex key extractors aren't allowed to take arguments. An alternative would be to define an index for each serotype, but I don't see how to write the MultiIndex container typedef ... in such an extensible way. I will be changing the number of serotypes between simulations. (Do experienced programmers think this should be possible? I'll attempt it if so.) There are 2^(NUM_SEROTYPES) possible infection statuses. For small numbers of serotypes, I could use a single index based on this number (or a binary string) and come up with some mapping from this key to actual infection status. Counting is still darn slow. I could maintain a separate structure counting the total numbers of infecteds with each serotype. The synchrony is a bit of a pain, but the memory is fine. I would prefer a slicker option, since I would like to do further sorts on other host attributes (e.g., after counting the number infected with serotype s, count the number of those infected who are also in a particular household and have a particular age). Thanks in advance.

  • Connection string problems on shared hosting with sql server 2005 express

    - by dagogo
    hi i have problem connecting to my db on a shared hosting, my host provider says they deployed sql 2005 express on their database and i prepared my connection string as follows to take advantage of sql express. \ the data source nae i used originally was ./SQLExpress but my host provider asked that i change it to local host, although with the former it didnt connect, but still with the change as indicated above the error still comes up on access to my default page. the error is as follows; Server Error in '/' Application. Invalid value for key 'attachdbfilename'. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.ArgumentException: Invalid value for key 'attachdbfilename'.

  • .NET 4 ... Parallel.ForEach() question

    - by CirrusFlyer
    I understand that the new TPL (Task Parallel Library) has implemented the Parallel.ForEach() such that it works with "expressed parallelism." Meaning, it does not guarantee that your delegates will run in multiple threads, but rather it checks to see if the host platform has multiple cores, and if true, only then does it distribute the work across the cores (essentially 1 thread per core). If the host system does not have multiple cores (getting harder and harder to find such a computer) then it will run your code sequenceally like a "regular" foreach loop would. Pretty cool stuff, frankly. Normally I would do something like the following to place my long running operation on a background thread from the ThreadPool: ThreadPool.QueueUserWorkItem( new WaitCallback(targetMethod), new Object2PassIn() ); In a situation whereby the host computer only has a single core does the TPL's Parallel.ForEach() automatically place the invocation on a background thread? Or, should I manaully invoke any TPL calls from a background thead so that if I am executing from a single core computer at least that logic will be off of the GUI's dispatching thread? My concern is if I leave the TPL in charge of all this I want to ensure if it determines it's a single core box that it still marshalls the code that's inside of the Parallel.ForEach() loop on to a background thread like I would have done, so as to not block my GUI. Thanks for any thoughts or advice you may have ...

  • Cannot bind to IPv6 address

    - by ereOn
    I am facing a strange problem on my Ubuntu Karmic system. When I call getaddrinfo() with AI_PASSIVE and AF_UNSPEC, for an empty host and the UDP 12000 port to get a bindable address, I only get back one IPv4 result (0.0.0.0:12000 for instance). If I change my call and specify AF_INET6 instead of AF_UNSPEC, then getaddrinfo() returns "Name or service not known". Shouldn't I get [::]:12000 as a result ? The same thing happens if I set the host to ::1. When I call getaddrinfo() without AI_PASSIVE (to get a "connectable" address) for the host "localhost" and the UDP 12000 port, I first get [::1]:12000 then 127.0.0.1:12000. So apparently, my system is IPv6 ready (I can ping to both IPv4 and IPv6 addresses, as well as DNS resolution). But how is it that I can't get an IPv6 address to bind to with getaddrinfo() ? Do you guys have any idea about what could be wrong ? My OS is Ubuntu Karmic, fresh install without any networking tweaking. Thank you.

  • Print table data mysql php

    - by Marcelo
    Hi people, i'm having a problem trying to print some data of a table. I'm new at this php mysql stuff but i think my code is right. Here it is: <html> <body> <h1>Lista de usuários</h1> <?php $host="localhost"; // Host name $username="root"; // Mysql username $password=""; // Mysql password $db_name="sabs"; // Database name $tbl_name="doador"; // Table name // Connect to server and select database. mysql_connect("$host", "$username", "$password")or die("cannot connect"); mysql_select_db("$db_name")or die("cannot select DB"); $sql="SELECT * FROM $tbl_name"; $result=mysql_query($sql); while($rows = mysql_fetch_array($result)){ echo $row['id'] . " " .$row['nome'] . " " . $row['sobrenome'] . " " . $row['email'] . " " . $row['login'] . " " . $row['senha'] . " " . $row['idade'] . " ". $row['peso'] . " " . $row['fuma'] . " " . $row['sexo'] . " " . $row['doencas']; echo "<BR/>"; } mysql_close(); ?> </body> </html> All columns of the echo command exist in my table in the database. Don't get why it's not printing those values. Thanks for the attention.

  • Actionscript flex sockets and telnet

    - by MAC
    I am trying to make a flex application where it gets data from a telnet connection and I am running into a weird problem. To give a brief introduction, i want to read data from a process that exposes it through a socket. So if in the shell i type telnet localhost 8651i receive the xml and then the connection is closed (I get the following Connection closed by foreign host.) Anyway i found a simple tutorial online for flex that essentially is a telnet client and one would expect it to work but everything follows Murphy's laws and nothing ever works! Now i have messages being printed in every event handler and all places that i can think off. When i connect to the socket nothing happens, no event handler is triggered even the connect or close handler and if i do the following the socket.connected returns false! I get no errors, try catch raises no exception. I am at a loss as to whats going wrong? socket.connect(serverURL, portNumber); msg(socket.connected.toString()); Is there something about telnet that i do not know and its causing this to not work. Whats more interesting is why none of the events get fired. Another interesting thing is that i have some python code that does the same thing and its able to get the xml back! The following is the python code that works! def getStats(host, port): sock = socket.socket() sock.connect((host, port)) res = sock.recv(1024*1024*1024, socket.MSG_WAITALL) sock.close() return statFunc(res) So i ask you whats going wrong!!!!!! Is there some inherent problem with how flex handles sockets?

  • Create 2nd tables and add data

    - by Tyler Matema
    I have this task from school, and I am confuse and lost on how I got to do this. So basically I have to create 2 tables to the database but I have to created from php. I have created the first table, but not the second one for some reason. And then, I have to populate first and second tables with 10 and 20 sample records respectively, populate, does it mean like adding more fake users? if so is it like the code shown below? *I got error on the populating second part as well Thank you so much for the help. <?php $host = "host"; $user = "me"; $pswd = "password"; $dbnm = "db"; $conn = @mysqli_connect($host, $user, $pswd, $dbnm); if (!$conn) die ("<p>Couldn't connect to the server!<p>"); $selectData = @mysqli_select_db ($conn, $dbnm); if(!$selectData) { die ("<p>Database Not Selected</p>"); } //1st table $sql = "CREATE TABLE IF NOT EXISTS `friends` ( `friend_id` INT NOT NULL auto_increment, `friend_email` VARCHAR(20) NOT NULL, `password` VARCHAR(20) NOT NULL, `profile_name` VARCHAR(30) NOT NULL, `date_started` DATE NOT NULL, `num_of_friends` INT unsigned, PRIMARY KEY (`friend_id`) )"; //2nd table $sqlMyfriends = "CREATE TABLE `myfriends` ( `friend_id1` INT NOT NULL, `friend_id2` INT NOT NULL, )"; $query_result1 = @mysqli_query($conn, $sql); $query_result2 = @mysqli_query($conn, $sqlMyfriends); //populating 1st table $sqlSt3="INSERT INTO friends (friend_id, friend_email, password, profile_name, date_started, num_of_friends) VALUES('NULL','[email protected]','123','abc','2012-10-25', 5)"; $queryResult3 = @mysqli_query($dbConnect,$sqlSt3) //populating 2nd table $sqlSt13="INSERT INTO myfriends VALUES(1,2)"; $queryResult13=@mysqli_query($dbConnect,$sqlSt13); mysqli_close($conn); ?>

  • How to ensure nginx serves a request from an external IP?

    - by Matt
    I have a strange situation, where my nginx setup stopped handling external requests. I'm pretty stuck. If I hit the domain without a subdomain, I properly get redirected, however, if I request the full url, that fails and doesn't log anything, anywhere. I am able to curl localhost on the server itself, however when I attempt to curl from an external machine, it fails with: curl: (7) couldn't connect to host I've also noticed that bots can get through, I've seen Google hit the log every now and then. My nginx.conf file: upstream mongrels { server 127.0.0.1:5000; } server { listen 80; server_name culini.com; rewrite ^/(.*) http://www.culini.com/$1 permanent; } # the server directive is nginx's virtual host directive. server { # port to listen on.

  • powershell: use variable with wildcard with get-aduser

    - by user179037
    powershell newbie here. I am building a simple bit of code to help me find user's by entering letters of user names. How do I get a wildcard to work w/ a variable? this works: $name=read-host -prompt "enter user's first or last initial" $userInput=get-aduser -f {givenname -like 'A*' } cmd /c echo "output: $userInput" this does not: $name=read-host -prompt "enter user's first or last initial" $userInput=get-aduser -f {givenname -like '$name*' } cmd /c echo "output: $userInput" The first bit of code delivers a list of users with "A" in their name. Any suggestions woudl be appreciated. thanks

  • Hyper-V and Hyper-threading: On or off?

    - by CapBBeard
    Hey all, With the new Xeon CPUs supporting Hyper-threading, what is the current wisdom with regard to using it (or not) on a Hyper-V host machine? I was originally under the impression that turning it on in a virtual host environment could be detrimental as the 'extra' CPUs were not true cores. However I've also read (unconfirmed) comments along the lines of MS doing some hard work to get Hyper-V running well in a Hyper-threading environment. Does anyone have any solid information or experience in this regard? Cheers!

  • SCVMM 2012 R2 - Installing Virtual Switch Fails with Error 2916

    - by Brian M.
    So I've been attempting to teach myself SCVMM 2012 and Hyper-V Server 2012 R2, and I seem to have hit a snag. I've connected my Hyper-V Host to SCVMM 2012 successfully, and created a logical network, logical switch, and uplink port profile (which I essentially blew through with the default settings). However when I attempt to create a virtual switch on my Hyper-V host, I run into an issue.

  • "No active network adapters found" Hyper-V 2008 R2

    - by mnemosyn
    I fiddled around with the virtual network settings of my Hyper-V server, because Windows Update failed to run in the VMs. I set the flag that makes the NIC exclusively usable by the VM. Now, the host system tells me it has no active network adapters. What does that even mean? According to netsh, there are three enabled network connections. I tried to restart the NICs using devcon.exe (the correct x64 version), but that doesn't make any difference - still, devcon reports the NICs are there and they are activated?! Is there any way I can force the host to re-enable the NICs?

  • GRE keepalive with Linux and RouterOS

    - by eri
    I have a Linux host and couple of routerboadrs. I created a GRE tunnel, but Linux does not answer keepalive packages. Then router mark gre connection as unreachable, so I cant send to Linux host from router subnet. If linux sends something into tunnel (ping, etc.) - RouterOS mark connection as reacheble. Second and next packages routed nicely until one minute idle (no traffic). Tunnel in linux a make in this way: remote=x.x.x.x dev=gre21 network=10.21.0.0/16 ip tunnel add ${dev} mode gre remote ${remote} ttl 255 ip addr add 172.16.1.1/24 peer 172.16.1.21 dev ${dev} ip link set ${dev} up ip route add ${network} dev ${dev} And ip l: 14: gre21: <POINTOPOINT,NOARP,UP,LOWER_UP> mtu 1476 qdisc noqueue state UNKNOWN link/gre 0.0.0.0 peer 109.60.170.15 How to set state "running"? How to keep alive tunnel? Ping in cron?

  • SQL Server Licensing in a VMware vSphere Cluster

    - by Helvick
    If I have SQL Server 2008 instances running in virtual machines on a VMware vSphere cluster with vMotion\DRS enabled so that the VM's can (potentially) run on any one of the physical servers in the cluster what precisely are the license requirements? For example assume that I have 4 physical ESX Hosts with dual physical CPU's and 3 separate single vCPU Virtual Machines running SQL Server 2008 running in that cluster. How many SQL Standard Processor licenses would I need? Is it 3 (one per VM) or 12 (one per VM on each physical host) or something else? How many SQL Enterprise Processor licenses would I need? Is it 3 (one per VM) or 8 (one for each physical CPU in the cluster) or, again, something else? The range in the list prices for these options goes from $17k to $200k so getting it right is quite important. Bonus question: If I choose the Server+CAL licensing model do I need to buy multiple Server instance licenses for each of the ESX hosts (so 12 copies of the SQL Server Standard server license so that there are enough licenses on each host to run all VM's) or again can I just license the VM and what difference would using Enterprise per server licensing make? Edited to Add Having spent some time reading the SQL 2008 Licensing Guide (63 Pages! Includes Maps!*) I've come across this: • Under the Server/CAL model, you may run unlimited instances of SQL Server 2008 Enterprise within the server farm, and move those instances freely, as long as those instances are not running on more servers than the number of licenses assigned to the server farm. • Under the Per Processor model, you effectively count the greatest number of physical processors that may support running instances of SQL Server 2008 Enterprise at any one time across the server farm and assign that number of Processor licenses And earlier: ..For SQL Server, these rule changes apply to SQL Server 2008 Enterprise only. By my reading this means that for my 3 VM's I only need 3 SQL 2008 Enterprise Processor Licenses or one copy of Server Enterprise + CALs for the cluster. By implication it means that I have to license all processors if I choose SQL 2008 Standard Processor licensing or that I have to buy a copy of SQL Server 2008 Standard for each ESX host if I choose to use CALs. *There is a map to demonstrate that a Server Farm cannot extend across an area broader than 3 timezones unless it's in the European Free Trade Area, I wasn't expecting that when I started reading it.

  • AppCmd returns error: Object 'SET' is not supported

    - by RHPT
    I am trying to set SSL Host Headers and Secure Site Bindings in IIS7. I followed the directions on this website http://www.digicert.com/ssl-support/ssl-host-headers-iis-7.htm (among others), but when I run the appcmd command mentioned, I get the error "Object 'SET' is not supported. Run 'appcmd.exe /?' to display supported objects". I have also tryed "appcmd site set" but it still returns the same error. What am I doing wrong? The server I am working on is Windows 2008 R2 x64, if that matters. Thank you.

  • LVM mirror attempt results in "Insufficient free space"

    Attempting to add a disk to mirror an LVM volume on CentOS 7 always fails with "Insufficient free space: 1 extents needed, but only 0 available". Having searched for a solution, I have tried specifying disks, multiple logging options, adding 3rd log partition, but have not found a solution Not sure if I am making a rookie mistake, or there is something more subtle wrong (I am more familiar with ZFS, new to using LVM): # lvconvert -m1 centos_bi/home Insufficient free space: 1 extents needed, but only 0 available # lvconvert -m1 --corelog centos_bi/home Insufficient free space: 1 extents needed, but only 0 available # lvconvert -m1 --corelog --alloc anywhere centos_bi/home Insufficient free space: 1 extents needed, but only 0 available # lvconvert -m1 --mirrorlog mirrored --alloc anywhere centos_bi/home /dev/sda2 Insufficient free space: 1 extents needed, but only 0 available # lvconvert -m1 --corelog --alloc anywhere centos_bi/home /dev/sdi2 /dev/sda2 Insufficient free space: 1 extents needed, but only 0 available The two disks are of the same size, and have identical partition layouts via "sfdisk -d /dev/sdi part_table; sfdisk /dev/sda < part_table".

  • Disable reverse PTR check in Zimbra and force accept from invalid domains

    - by ewwhite
    I've moved an older Sendmail/Dovecot system to a Zimbra community edition system. I need to be able to receive messages from certain standalone Linux hosts that may not have valid A records or proper reverse DNS entries established (e.g. AT&T is the ISP or systems sitting on a consumer-level ISP). Establishing the reverse DNS or setting a SMARTHOST is not an option. The error I get in zimbra.log is: zimbra postfix/smtp[2200]: DB83B231B53: to=<root@host_name.baddomain.com>, relay=none, delay=0.07, delays=0.06/0/0/0, dsn=5.4.4, status=bounced (Host or domain name not found. Name service error for name=host_name.baddomain.com type=A: Host not found How can I override this? Is this more of a Postfix issue or is it Zimbra? edit - The problem seems to be with an underscore in the hostname of the server. So it's a problem with root@host_name.baddomain.com. Again, how can I override this in Zimbra?

  • Standard Protection:Prevent IRC communication

    - by awe
    I have McAffee virusscan on my work computer, and every time I start up, I get 2 log entries like this: Blocked by port blocking rule C:\Program Files\Skype\Phone\Skype.exe Anti-virus Standard Protection:Prevent IRC communication The difference between the two, is that at the end there are 2 different IP addresses (which I don't recognise as belongs to us) with port :6667 on one and :6669 on the other. Although this is logged, Skype seems to work as expected; including talking, chatting and screen sharing (new feature in Skype 4.1). Anyone knows anything about what this is? EDIT: I also have a Skype certified plugin in Skype called Cucku Backup. I did not find anything in the documentation that Cucku is trying to access these ports through Skype, but it could be...? EDIT2: I did a search on the IP addresses in question on www.webyield.net, and resulted in the following: IP 71.251.72.173 (this one used port :6667): Host name: pool-71-251-72-173.tampfl.fios.verizon.net IP 79.87.54.165 (this one used port :6669): Host name: 165.54.87-79.rev.gaoland.net

  • Mac OS X bypass proxy for certain domains

    - by Brian
    In college I'm behind a proxy. When I try to visit one of my local Apache virtual hosts behind the proxy, then my college DNS attempts to resolve the host, thus bypassing my local host file. In the advanced setting for proxies you seem to be able to enter values into "Bypass proxy settings for these Hosts & Domains". I added the last 2 to the end - "*.local, 169.254/16, *.dev, *.sb". But it doesn't work. Is there a solution?

  • Choice of operating systems for a Rackspace cloud installation

    - by riteshmnayak
    I am planning to use Rackspace cloud services to host a java web application and also run apace for wordpress and trac. What would be a stable operating system to host such an application. My requirements are that the core OS bundle should be minimalistic (so I can install only what I want), consume very little memory and be performant. I would also need it to contain softwares for the common lamp stack, J2EE stack etc. A supported package manager would be lovely. My choices are listed below. RHEL 5.3 or 5.4 Debian Lenny Ubuntu 8.04 onwards Centos 5.3 or 5.4 Arch 2009.02 Gentoo 2008.0 or 10.1 Fedora 11 or 12 PS: can somebody add the rackspace tag to this? Edit to remove this line as well. Thanks

  • Can I minimize VMWare Workstation from exclusive mode?

    - by Blorgbeard
    I am running a VM on two monitors, in fullscreen exclusive mode. I would like to be able to minimize the VM and mess around in the Host, then go back to the VM. I can do this by pressing CTRL+ALT to get out of fullscreen mode, but this puts the VM back onto a single monitor, which moves all my VM's windows back to the main virtual screen. This is annoying, because when I come back to the VM, I have to go back to multiple monitor mode, and move windows back to where they should be. Is there a way to temporarily escape from fullscreen exclusive mode, without disturbing multi-monitor layout? I should note that I'm only using exclusive mode to get rid of the popup toolbar that otherwise appears when your mouse gets too close to the top of the screen. If there's another way to kill that, please let me know. My host and guest are both Windows 7 x64, and I'm running VMWare Workstation 8.
