  • C++: Accessing std::map keys and values

    - by Jay
    How do you access an std::vector of the keys or values of an std::map? Thanks. Edit: I would like to access the actual elements, not just copies of their contents. essentially I want a reference, not a copy. This is essentially what I am wanting to do: std::map<std::string, GLuint> textures_map; // fill map glGenTextures( textures_map.size(), &textures_map.access_values_somehow[0] );

  • Foreign Keys Duplicated in DataGridView

    - by John Doe
    I created a Windows Forms Application to which I added a DataGridView and LINQ to SQL Classes from one of my databases. I can successfully bind one of my database's tables to my DataGridView: var dataSource = from c in _db.NetworkedEquipments select c; dataGridView1.DataSource = dataSource; However, the foreign keys get duplicated, that is, the columns appear twice. How can I prevent this?

  • when to index on multiple keys in mongodb

    - by Evan
    say I have an Item document with :price and :qty fields. I sometimes want to find all documents matching a given :price AND :qty, and at other times it will be either :price on its own or :qty on its own. I have already indexed the :price and :qty keys, but do I also need to create a compound index on both together or are the single key indexes enough?

  • Fastest way to add prefix to array keys?

    - by Kirzilla
    Hello, What is the fastes way to add string prefixes to array keys? was $array = array( '1' => 'val1', '2' => 'val2', ); needed $array = array( 'prefix1' => 'val1', 'prefix2' => 'val2', ); According to http://www.phpbench.com/ (see Modify Loop) I should use "for" statement, but probably there is more elegant way? Thank you.

  • Iterating over key/value pairs in a dict sorted by keys

    - by Helper Method
    I have the following code, which just print the key/value pairs in a dict (the pairs are sorted by keys): for word, count in sorted(count_words(filename).items()): print word, count However, calling iteritems() instead of items() produces the same output for word, count in sorted(count_words(filename).iteritems()): print word, count Now, which one should I choose in this situation? I consulted the Python tutorial but it doesn't really answer my question.

  • Dual Exchange 2010 on different VM + single public IP + multiple domains

    - by Shivan Raptor
    Here is the scenario: I have 2 Exchange Server 2010 on 2 different Virtual Machines, created by and based on Hyper-V. They have IP and domain: 192.168.5.11, domainA.com ; and 192.168.5.12, domainB.com respectively. The problem is, I only have 1 public IP, say 123.123.1.1 . How do I configure the settings so that I can successfully receive emails using both Exchange servers? Given that I cannot use single Exchange server for multiple domains. -- UPDATE -- To clarify, the domainA.com and domainB.com mentioned above are website domains, instead of multiple Active Directory forests. Users of the two Exchange Server shares the same Active Directory. I know that ONE Exchange Server can handle multiple domains, but I would like to separate them into different Virtual Machines, for load balancing and data separation.

  • KVM recommendations

    - by alex
    I recently tried out a cheaper KVM solution, a dual monitor one with a USB hub and audio/mic support. It seemed the perfect KVM. However, these are my experiences. When using my keyboard via the PS/2 connection, none of my multimedia keys work (useful, because it has a volume control and my speakers do not, only on a wireless remote control.) I plugged the keyboard in via the USB port - and it seemed to work. However, I believe to switch the hub from PC to Mac, you need to use a keyboard combo, which is only supported when the keyboard is plugged in via PS/2 Sometimes the middle mouse button doesn't work when connected via PS/2. The multi monitor is VGA - I just found out by the looks of things my Mac Mini outputs DVI Digital only (though this is my fault!). Mac works with 2 screens, but switching and switching back can cause it not to display on the 2nd screen unless I go detect displays again. My question is - is there a KVM out there that supports these features? USB keyboard and mouse inputs will full multimedia keys support Dual monitor DVI connections Hotkey to change PCs and physical button USB hub Emulate screens attached when switching to a different computer Works with PC and Mac Audio / Microphone support Does one exist, that won't cost the world? So far the only one that seems to support all this (that I can tell) is this one. UPDATE I ended up buying the Aten CS1642. It's expensive, but it seems to work great!

  • Multiple LiveCD iso's on a single USB drive

    - by Keck
    I am looking to create a USB flash drive that I can put multiple LiveCD iso's on and select which boots from startup. The ideal candidate supports linux and windows based iso's, and is relatively simple. It also must have some reasonable process for adding and removing iso from the drive/list. Things that I'm not looking for this specific question: UBCD or other swiss-army knife livecd's. The point is to boot any one of multiple CD's, not to boot a (certainly useful) utility CD. Installing a single LiveCD to a USB drive. I'd like to have multiple iso images, selectable at startup. I don't have a specific purpose in mind, possibilties include a single drive with a knoppix variant, ubuntu desktop, UBCD for dos, UBCD4Win, the Offline NT Password Cracker, etc. Flexible and easy to use are the name of the game!

  • Cloud Computing - Multiple Physical Computers, One Logical Computer

    - by bundini
    I know that you can set up multiple virtual machines per physical computer. I'm wondering if it's possible to make multiple physical computers behave as one logical unit? Fundamentally the way I imagine it working is that you can throw 10 computers into a facility one day. You've got one client that requires the equivalent of two computers worth, and 100 others that eat up the remaining 8. As demands change you're just reallocating logical resources, maybe the 2 computer client now requires a third physical system. You just add it to the cloud, and don't worry about sharding the database, or migrating data over to a new server. Can it work this way? If yes, why would anyone ever do things like hand partition their database servers anymore? Just add more computing resources. You scale horizontally with the hardware, but your server appears to scale vertically. There's no need to modify your application's supporting infrastructure to support multiple databases etc.

  • Smartcards for storing gpg/ssh keys (Linux) - what do I need?

    - by Ninefingers
    Hi All, I'm interested in storing my SSH keys and gpg keys on a smartcard for added security. However, I'm a bit uncertain on a few points, which are as follows: How many keys can I get on a card? I assume both SSH and GPG can store keys on the card. Is there a limit to key size? I see a lot of cards saying they support 2048-bit keys, what about larger sizes? Hardware: can anyone recommend a card/reader combination that works well? I've done a fair amount of research and it seems PC/SC readers can be a bit iffy - is this your experience? Have I missed anything I should be asking? Are there any other hurdles? I'm aware fsf europe give away cards with membership - I'm not sure I want to join, but... are these cards any good?

  • Choose between multiple keyboard layouts for different users in GDM3

    - by Daniel Wagner
    I am trying to set up a computer with multiple users each with different preferred keyboard layouts. The biggest sticking point right now is allowing each to log in comfortably. GDM used to offer a way to choose keyboard layout, but I can't discover how to set this up in GDM3. All the solutions I found when Googling this problem suggest changing the keyboard layout in xorg.conf, but that only sets a different single layout and still does not seem to allow me to change the layout between multiple choices. How can I allow multiple layouts when logging in?

  • How to specify multiple HostName/Port combinations in .ssh/config

    - by leoluk
    I have multiple notebooks and workstations which pull and push from multiple Mercurial repositories on a central server. I usually use .ssh/config to set an alias: Host repo-server HostName server.somedomain User user143 IdentityOnly yes IdentityFile ~/hgkey Port 156 ... and some more options, you get the idea. I can then simply do a hg push ssh://repo-server//hgroot/someproject on every local repository, and I can change the server address and port in one place. For workstations, this works fine, but the notebooks can access the server either from inside the network or from outside, using a different address and a different port. Is there any way I can specify multiple HostName/Port combinations so that SSH automatically tries them in order? This way, the users could push and pull without having to care about the correct address. (of course, using a VPN would be the most correct solution)

  • RSS reader that supports multiple google accounts?

    - by Koen027
    I've been looking around for an RSS reader that can handle more than 1 google account? I have multiple gmail addresses for different things in life. I separate mails this way and also RSS feeds. This works fine on google reader, but i would like to have a desktop app that can handle multiple accounts, like Thunderbird can handle multiple mail accounts. All the desktop clients I've found so far ask you for 1 google account and that's where it ends. You can't add anymore.

  • insert, delete etc. keys not working on Cherry Strait keyboard

    - by Brabster
    Hey folks, I got a Cherry Strait USB wired keyboard for xmas and I've been unable to get several keys working under Ubuntu 10.10 or Win XP. There are a few keys. including the Print Screen key, insert, end, delete, pg up, pg down and home. I've not been able to identify any others that aren't working. I'm not sure as to the best approach to determine what's wrong. Is there any way to confirm whether there is any output from the keyboard in response to pressing those keys, ideally in Ubuntu as that's where I spend most of my time so that I know if it's a fault with the device itself? (I've tried different USB ports and also hitting those keys whilst in the Keyboard Shortcuts app, no response to these keys)

  • How to lookup a value in a table with multiple criteria

    - by php-b-grader
    I have a data sheet with multiple values in multiple columns. I have a qty and a current price which when multiplied out gives me the current revenue (CurRev). I want to use this lookup table to give me the new revenue (NewRev) from the new price but can't figure out how to do multiple ifs in a lookup. What I want is to build a new column that checks the "Product", "Tier" and "Location/State" and gives me the new price from the lookup table (above) and then multiply that by the qty. e.g. Data > Product, Tier, Location, Qty, CurRev, NewRev > Product1, Tier1, VIC, 2, $1000.00, $6000 (2 x $3000) > Product2, Tier3, NSW, 1, $100.00, $200 (1 x $200) > Product1, Tier3, SA, 5, $250.00, $750 (5 x $150) > Product3, Tier1, ACT, 5, $100.00, $500(5 x $100) > Product2, Tier3, QLD, 2, $150.00, $240 (2 x $240) Worst case, if I just get the new rate I can create another column

  • Easiest way to remove Keys from a 2D Array?

    - by dbemerlin
    Hi, I have an Array that looks like this: array( 0 => array( 'key1' => 'a', 'key2' => 'b', 'key3' => 'c' ), 1 => array( 'key1' => 'c', 'key2' => 'b', 'key3' => 'a' ), ... ) I need a function to get an array containing just a (variable) number of keys, i.e. reduce_array(array('key1', 'key3')); should return: array( 0 => array( 'key1' => 'a', 'key3' => 'c' ), 1 => array( 'key1' => 'c', 'key3' => 'a' ), ... ) What is the easiest way to do this? If possible without any additional helper function like array_filter or array_map as my coworkers already complain about me using too many functions. The source array will always have the given keys so it's not required to check for existance. Bonus points if the values are unique (the keys will always be related to each other, meaning that if key1 has value a then the other key(s) will always have value b). My current solution which works but is quite clumsy (even the name is horrible but can't find a better one): function get_unique_values_from_array_by_keys(array $array, array $keys) { $result = array(); $found = array(); if (count($keys) > 0) { foreach ($array as $item) { if (in_array($item[$keys[0]], $found)) continue; array_push($found, $item[$keys[0]]); $result_item = array(); foreach ($keys as $key) { $result_item[$key] = $item[$key]; } array_push($result, $result_item); } } return $result; } Addition: PHP Version is 5.1.6.

  • Managing multiple reverse proxies for one virtual host in apache2

    - by Chris Betti
    I have many reverse proxies defined for my js-host VirtualHost, like so: /etc/apache2/sites-available/js-host <VirtualHost *:80> ServerName js-host.example.com [...] ProxyPreserveHost On ProxyPass /serviceA http://192.168.100.50/ ProxyPassReverse /serviceA http://192.168.100.50/ ProxyPass /serviceB http://192.168.100.51/ ProxyPassReverse /serviceB http://192.168.100.51/ [...] ProxyPass /serviceZ http://192.168.100.75/ ProxyPassReverse /serviceZ http://192.168.100.75/ </VirtualHost> The js-host site is acting as shared config for all of the reverse proxies. This works, but managing the proxies involves edits to the shared config, and an apache2 restart. Is there a way to manage individual proxies with a2ensite and a2dissite (or a better alternative)? My main objective is to isolate each proxy config as a separate file, and manage it via commands. First Attempt I tried making separate files with their own VirtualHost entries for each service: /etc/apache2/sites-available/js-host-serviceA <VirtualHost *:80> ServerName js-host.example.com [...] ProxyPass /serviceA http://192.168.100.50/ ProxyPassReverse /serviceA http://192.168.100.50/ </VirtualHost> /etc/apache2/sites-available/js-host-serviceB <VirtualHost *:80> ServerName js-host.example.com [...] ProxyPass /serviceB http://192.168.100.51/ ProxyPassReverse /serviceB http://192.168.100.51/ </VirtualHost> The problem with this is apache2 loads the first VirtualHost for a particular ServerName, and ignores the rest. They aren't "merged" somehow as I'd hoped.
