  • hash tables and 2d vectors

    - by Sunil
    I want to push a 2d vector into a hash table row by row and later search for a row (vector) in the hash table and want to be able to find it. I want to do something like #include <iostream> #include <set> #include <vector> using namespace std; int main(){ std::set < vector<int> > myset; vector< vector<int> > v; int k = 0; for ( int i = 0; i < 5; i++ ) { v.push_back ( vector<int>() ); for ( int j = 0; j < 5; j++ ) v[i].push_back ( k++ ); } for ( int i = 0; i < 5; i++ ) { std::copy(v[i].begin(),v[i].end(),std::inserter(myset)); // This is not correct but what is the right way ? // and also here, I want to search for a particular vector if it exists in the table. for ex. the second row of vector v. } return 0; } I'm not sure how to insert and look up a vector in a set. So if nybody could guide me, it will be helpful. Thanks

  • How to identify end of InputStream in java

    - by Vardhaman
    I am trying to read bytes from server using Socket program, ie I am using InputStream to read the bytes. If I pass the length size I am able to read the bytes, but I am not sure what may be the length. So I am not able initialize the byte array. Also I tried while (in.read() !=-1), I observered it loop works fine when the data is sent , but the next line after the loop is not executable , I feel its still looking for the data in the stream but there is no ata. If I close the Server connection , then my client will execute the next line followed to the loop. I am not sure where I am going wrong? this.in = socket.getInputStream(); int dataInt = this.in.read(); while(dataInt != -1){ System.out.print(","+i+"--"+dataInt); i++; dataInt = this.in.read(); } System.out.print("End Of loop"); I get the output as:- ,1--0,2--62,3--96,4--131,5--142,6--1,7--133,8--2,9--16,10--48,11--56,12--1,13--0,14--14,15--128,16--0,17--0,18--0,19--48,20--0,21--0,22--0,23--0,24--0,25--1,26--0,27--0,28--38,29--114,30--23,31--20,32--70,33--3,34--20,35--1,36--133,37--48,38--51,39--49,40--52,41--49,42--55,43--49,44--52,45--52,46--54,47--55,48--50,49--51,50--52,51--48,52--53,53--56,54--51,55--48,56--48,57--57,58--57,59--57,60--57,61--57,62--57,63--57,64--56 But no output for :- End Of loop Please guide how shall I close the loop?

  • NSInvalidArgumentException accessing NSMutableArray in a UITableView

    - by kashar28
    Hello, I am a noob in iPhone programming so kindly guide me. I have 5 buttons in a custom UITableViewCell. Following is the code to determine which button was pressed. In ProductTableCustomCell.m -(IBAction) getRating:(id) sender { ProductTableView *ptv = (ProductTableView *)self.superview; if((UIButton *) sender == box1) { [ptv.totalComments addObject:@"BOX2"]; } else if((UIButton *) sender == box2){ NSLog(@"Box2"); [ptv.totalComments addObject:@"BOX2"]; NSLog(@"Am I here?"); }else if((UIButton *) sender == box3){ NSLog(@"Box3"); [ptv.totalComments addObject:@"BOX3"]; }else if((UIButton *) sender == box4){ NSLog(@"Box4"); [ptv.totalComments addObject:@"BOX4"]; }else if((UIButton *) sender == box5){ NSLog(@"Box5"); [ptv.totalComments addObject:@"BOX5"]; } } Here totalComments is a NSMutableArray in ProductTableView which is a UITableView. If for example I click button2, then I get the following error: * Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '* -[UITableView totalComments]: unrecognized selector sent to instance 0x4036e00'** I don't understand the problem. I have double checked the IBOutlets and IBActions as well. Everything seems proper. I think the problem is in the superview.Any help would be appreciated.

  • VLC (Server) re-stream Security Camera Feed

    - by Aaron
    I purchased a Swann Home Security DVR system and was hoping for some help on how to duplicate the streaming video on my server. In order to get their web view (streaming video in the browser) to work, I had to install the following plugins: HiDvrPlugin.dmg for mac. Hidvrocx.cab for Windows. I was originally thinking it was a sign of some form of DRM? Maybe. Maybe not. HTML wise, the following code is in the source of the safari version of the web view: <embed pluginspage="SurveilClient.dmg" width="10px" height="10px" type="application/x-scplugin" id="MacDiv" style="height: 592px; width: 720px; left: 278px; top: 61px; "> It seems to be the main display area. Using wireshark, I am able to see that the video stream is on port 9000. However, I have no idea what type of stream it is. I've tried opening it in VLC with no such luck. http://dvr_ip:9000 tcp://dvr_ip:9000 My hope was to do the following to redistribute the feed vlc dvr_ip:9000 --sout h264-version-on-localhost:3000 TLDR; Trying to re-distribute a stream from a security camera (can't tell the format) using vlc (re-distribute via h.264 / HTML5). Not sure how to accomplish this. Is it possible that the software has some type of DRM that only the plugins can decode?

  • Performance analytics via DBMS "plugins", or other solution

    - by Polynomial
    I'm working on a systems monitoring product that currently focuses on performance at the system level. We're expanding out to monitoring database systems. Right now we can fetch simple performance information from a selection of DBMS, like connection count, disk IO rates, lock wait times, etc. However, we'd really like a way to measure the execution time of every query going into a DBMS, without requiring the client to implement monitoring in their application code. Some potential solutions might be: Some sort of proxy that sits between client and server. SSL might be an issue here, plus it requires us to reverse engineer and implement the network protocol for each DBMS. Plugin for each DBMS system that automatically records performance information when a query comes in. Other problems include "anonymising" the SQL, i.e. taking something like SELECT * FROM products WHERE price > 20 AND name LIKE "%disk%" and producing SELECT * FROM products WHERE price > ? AND name LIKE "%?%", though this shouldn't be too difficult with some clever parsing and regex. We're mainly focusing on: MySQL MSSQL Oracle Redis mongodb memcached Are there any plugin-style mechanisms we can utilise for any of these? Or is there a simpler solution?

  • PXE boot and DHCP server configuration Failing Auto Installation

    - by Harihara Vinayakaram
    I have a ISC DHCP Server installed on Ubuntu 9.10 . I have managed to successfully boot a PXE client , obtain a DHCP address and load the initrd.gz file. But I am facing a vague problem when the debian installer starts up and tries to get a DHCP server The client send a DHCP request and I verified that is the same MAC Address. But I get a DHCP DECLINE (The client declines the address ). It offers all the address in the pool and then there is a DHCP NAK (no more free leases ) I tried using the Option no-ping, and also option one-client-one-lease but it does not help . If I set the client to use a fixed-address then the above problem is not there and the installation proceeds smoothly Can you give me any clues on what should be the DHCP server configuration My dhcpd.conf looks like this { ddns-update-style none; option domain-name "hadoop-myorg.org"; option domain-name-servers 192.168.3.5; default-lease-time 600; max-lease-time 7200; group { filename "pxelinux.0"; next-server 192.168.13.184; host hadoop1 { hardware ethernet 90:e6:ba:d5:53:f8; } } subnet 192.168.13.0 netmask 255.255.255.0 { option routers 10.0.0.254; pool { option domain-name-servers 192.168.3.5; max-lease-time 3000; range 192.168.13.55 192.168.13.65; deny unknown-clients; } } }

  • Interpreting Inkscape SVG path coordinates for HTML map

    - by tovare
    I needed some coordinates for a HTML MAP and tried to use inkskape by opening the image and just draw a path with my polygon coordinates. My document properties are set to 256 x 256 pixels and units: px When opening the svg file i get coordinates which are not immediately apparent. <path style="fill:none;stroke:#000000;stroke-width:1px;stroke-linecap:butt; stroke-linejoin:miter;stroke-opacity:1" d="m 23.864407,126.91525 3.254237, 44.47458 35.79661, 44.47458 71.593216, 19.52542 71.59322, -37.9661 22.77967, -72.67797 L 218.0339, 64 192,49.898305 l -32.54237, 8.677966 -18.44068, -35.79661 1.08474, -17.3559322 -71.593215,0 L 45.559322,34.711864 35. 79661,57.491525 5.4237288, 74.847458 6.5084746,101.9661 23.864407,126.91525 z" id="path2840" /> How can I get coordinates I can use ? The original image The SVG file from inkscape Link to SVG Progress: I tried a tool called InkscapeMap which looks promising and simple, but unfortunately it looks like it didn't work with this particular svn file. Solved! Saving the file as a Plain SVG solved the problem and InkscapeMap worked perfectly. (Btw. saving as an optimized svg caused a parsing error) Update 13.11 Using inkscapeMap 0.6 and Inkscape 0.48 i needed to uncheck relative coordinates in SVG output preferences. Also if you get a C error message, hunt down the polygon with a C in it, and redraw the polygon using the XML editor in inkscape. Update 25.11.2011 I modified the source to improve parsing. http://tovare.com/articles/createhtmlimagemapsusinginkscape/

  • Making always-on-top windows follow the same MRU order as other windows

    - by nitro2k01
    Note: I'm using Windows 7 with the classical alt-tab style, ie the registry key AltTabSettings set to 1. I want to use MRU (most recently used) ordering of windows in the alt-tab list. However, because the windows are ordered in the Z order of the windows rather than actual MRU, this sometimes gives a different order after switching from an always-on-top application. Example: I have applications A, B and C open. A is set to always-on-top while the others aren't. A is focused. I now press alt-tab and application B is focused. I now press alt-tab but instead of application A receiving focus, application C does. Since A has a higher Z order, it's now left of application B, despite being the most recently used, and application C is placed right of B and is the one first getting focus by the cursor. To switch to application A, I need to press shift+alt-tab or cycle through all the other open windows. This is annoying when flicking focus back and forth between an always-on-top application and one that isn't always-on-top. Is there a way to make the alt-tab ordering strictly MRU?

  • Ubuntu in VirtualBox File Modified Time in Future and PHP slow file operations

    - by user1750
    For some reason, some of my files have a last modified date in the future. In addition to this, file operations in PHP are SUPER slow. For example, rebuilding the Symfony2 cache can take over 40 seconds (its takes 1-2 on my MacBook Pro). Notice the time for ListingsCRUDController.php. It just says "2012". In order see the date more clearly I ran ls --time-style="full-iso" -l For some reason it shows that this file's last modified date is ~5 hours into the future. System time: To make things more confusing, the system will intermittently speed up. Suddenly, my app will start serving requests in 1-2 seconds (down from 40 seconds) for no apparent reason. I mean I don't do anything to my code/system config - it just changes. Also, during a slow PHP request, the php5-fpm process (nginx) uses 100% of the CPU for the duration of the request. This is the second VM this has happened on and I need to know why its doing this. It has become unusable. Information About My Setup VirtualBox 4.2.0 Host: Macbook Pro Guest: Ubuntu Server 12.04 Package dkms is installed Timezones match for Ubuntu and PHP. Things I've Tried Both Apache and Nginx. APC enabled and disabled. Xdebug enabled and disabled. 1 processor up to 4 processors. 1gb memory up to 4gb memory. I've installed Ubuntu using the regular kernel and the VM kernel.

  • Write access from a Windows client via a ZFS SMB, to a file created on the host in OpenIndiana

    - by Gerald Kaszuba
    I've got an OpenIndiana server running ZFS that is shared using a nobody user and group. I don't fully understand Solaris ACL permissions, but I do know Linux style permissions. The client is Windows 8 and the server is OpenIndiana is oi_148. I'm failing to work out how to make write permission work correctly for the Windows client. It is able to make new files, but can not modify files created by the shell in OpenIndiana. When a file ("local file") is created locally as the user nobody in bash, and another file ("smb file") created remotely via SMB (as nobody also), they are quite different in permissions: # ls -V -rw-r--r-- 1 nobody nobody 0 Dec 2 12:24 local file owner@:rw-p--aARWcCos:-------:allow group@:r-----a-R-c--s:-------:allow everyone@:r-----a-R-c--s:-------:allow -rwx------+ 1 nobody nobody 0 Dec 2 12:24 smb file user:nobody:rwxpdDaARWcCos:-------:allow group:2147483648:rwxpdDaARWcCos:-------:allow In bash, I'm able to write to smb file, but vice versa, the Windows client is not able to write to local file. This is confusing to me because it appears that it should allow the SMB client to write to local file, because nobody is the owner and it has a w in the ACL. The sharesmb setting is is fairly boring, although I'm hoping there can something to set in here similar to a umask: sharesmb name=shared,guestok=true How can I make these two work together and have a symmetrical permission system, where both SMB and the local user produce the same permissions? Is there some sort of ACL that can set at the root of the file system to allow all files to be created in a similar manner?

  • Is On-The-Fly string replacement possible using GreaseMonkey and Firefox

    - by Gary M. Mugford
    I have looked for means to stop Brightcove videos from autostarting in Firefox and have come to the conclusion it isn't possible without external programming via something like Grease Monkey. However, I'm not proficient in javascript let alone GM. So I thought I'd ask here first whether what I want to do is feasible, or whether it's a fool's errand. What I want to accomplish is have a site specific script executed to replace a string value on the run in that site's code. Specifically, what I am looking for is something GM-style that would do this: if site_domain = 'www.SiteWithAutoPlayVideos.com' then replace_all('<param name="autoStart" value="true" />', '<param name="autoStart" value="false" />'); Having looked through Super User for anything GreaseMonkey that might relate, I see notices that the sandbox GM executes scripts in has to remain separate for security reasons. So, I suspect I might be in for disappointment. BUT if it is accomplishable and somebody here can confirm it, then I will do my best to struggle through the learning curve and get this noisome little problem put to rest. Yes, I have tried Flash Block and FlashDisable in order to attack this issue with no avail. Thanks in advance for your time.

  • Running multiple services on different servers with IPv6 and a FQDN

    - by Mark Henderson
    One of the things NAT has permitted us to do in the past decade is split physical services onto different servers whilst hiding behind a single interface. For example, I have example.com behind a NAT on 192.0.2.10. I port-forward :80 and :443 to my web server. I'm also port forward :25 to my mail server, and :3389 to a terminal server and :8080 to the web interface of my computer that downloads torrents, and the story goes on. So I have 5 port forwardings going to 4 different computers on example.com. Then, I go and get me some neat IPv6. I assign example.com an IPv6 address of 2001:db8:88:200::10. That's great for my websites, but I want to go to example.com:8080 to get to my torrents, or example:3389 to log on to my terminal server. How can I do this with IPv6, as there is no NAT. Sure, I could create a bunch of new DNS entries for each new service, but then I have to update all my clients who are used to just typing example.com to get to either the website or the terminal server. My users are dumber than two bricks so they won't remember to connect to rdp.example.com. What options do I have for keeping NAT-style functionality with IPv6? In case you haven't figured it out, the above scenario is not a real scenario for me, or perhaps anyone yet, but it's bound to happen eventually. You know, with devops and all.

  • Port forwarding for samba

    - by EternallyGreen
    Alright, here's the setup: Internet - Modem - WRT54G - hubs - winxp workstations & linux smb server. Its basically a home-style distributed internet connection setup, except its at a school. What I want is remote, offsite smb access. I figured I'd need to find out which ports need forwarding and then forward them to the server on the router. I'm told in another question on SF that multiple ports will need forwarding, and it gets somewhat complicated. One of the things I need to know is which ports require forwarding for this, and what complications or vulnerabilities could arise from this. Any additional information you think I should have before doing this would be great. I'm told SMB doesn't support encryption, which is fine. Given I set up authentication/access control, all this means is that once one of my users authenticates and starts downloading data, the unencrypted traffic could be intercepted and read by a MITM, correct? Given that that's the only problem arising from lack of encryption, this is of no concern to me. I suppose that it could also mean a MITM injecting false data into the data stream, eg: user requests file A, MITM intercepts and replaces the contents of file A with some false data. This isn't really an issue either, because my users would know that something was wrong, and its not likely anyone would have incentive to do this anyway. Another thing I've been informed of is Microsoft's poor implementation of SMB, and its crap track record for security. Does this apply if only the client-end is MS? My server is linux.

    - by Svyatoslavik
    How install ImageMagic 6.6.2 on Ubuntu 10.04 (lucid) Problem that lucid have old ImageMagic version(6.5.2) Its very important because me need work with SVG grafics, In my local pc I have ubuntu 11.04 and ImageMagic 6.6.2 and all work fine, In server I have 6.5... and I have problem. Reinstall ubuntu to 11.* this is no solution. I tried change /etc/apt/source.list from ubuntu 10.04 (lucid) to list from ubuntu 11.04 (natty) and update ImageMagic.

  • glib2 64-bit compile fails on Solaris 10

    - by Aaron
    I'm encountering a problem building glib-2.26.1 on a Solaris 10 box - 64-bit. Goo diligence doesn't turn anything up, but no matter what I do the build fails in the same way.

  • Joining Samba to Active Directory with local user authentication

    - by Ansel Pol
    I apologise that this is somewhat incoherent, but hopefully someone will be able to make enough sense of this to understand what I'm trying to achieve and provide pointers. I have a machine with two network interfaces connected to two different networks (one of which it's providing several other services for, such as DNS), running two separate instances of Samba, one bound to each interface. One of the instances is just a workgroup-style setup using share-level authentication, which is all working fine. The problem is that I'm looking to join the other instance to an MS Active Directory domain (provided by MS Windows Small Business Server 2003) to enable a subset of the domain users to access the shares from Windows machines on the other network. The users who need access from the domain environment have accounts (whose names are all-lowercase versions of their domain usernames) on the machine running Samba, but I'm not sure about how to map the UIDs and everything I've read concerns authenticating accounts on that machine against either AD or another LDAP server. To clarify: I only want the credentials for AD users accessing the non-workgroup Samba instance to be authenticated against AD, not the accounts on the machine running Samba. I hope this is sufficiently clear. EDIT: In addition to being able to access the Samba shares from AD, I do also need to be able to access a share on the domain from the machine running Samba but would still like everything non-Samba-related to authenticate locally.

  • No external src ip in log files (my router ip appears instead)

    - by bongo_fury
    I recently retired my workhorse WRT54G router/AP in favor of a Linksys EA2700. Since then, all inbound traffic (bound to an Ubuntu 10.02 box running LAMP)logged to Syslog, Apache's error and access logs, etc. (all behind said router) is getting logged with a src ip of 192.168.1.1, that of the router's internal ip. For example, here is an old entry from apache's access.log: 74.82.68.20 - - [22/Feb/2011:10:14:34 -0600] "GET /assets/css/style.css HTTP/1.1" 304 154 "http://example.com/view.php?event_id=1" "BlackBerry8520/5.0.0.822 Profile/MIDP-2.1 Configuration/CLDC-1.1 VendorID/100" And here is one since switching the router: 192.168.1.1 - - [05/Oct/2012:21:29:25 -0500] "GET /somedir/print.css HTTP/1.1" 200 650 "http://example.com/somedir/" "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:15.0) Gecko/20100101 Firefox/15.0.1"** That first field is the problem. Each and every entry in every log shows an "external" IP of 192.168.1.1, which isn't very helpful. Any ideas? Much thanks from a n00b!
