  • I want to scramble an array in PHP

    - by BRUL
    I want PHP to randomly create a multi-dimensional array by picking a vast amount of items out of predefined lists for n times, but never with 2 times the same. Let me put that to human words in a real-life example: i want to write a list of vegetables and meat and i want php to make a menu for me, with every day something else then yesterday. I tried and all i got was the scrambling but there were always doubles :s

  • Good, secure video chat program

    - by wag2639
    I'm looking for something similar to skype but basically just for me to video chat with my girlfriend. Skype has been kind of buggy lately with its recent iterations and doesn't seem to be progressing as much as when it was with its previous backers. Are there any good, secure video chat programs? Something that customizable and lets you choose framerate vs pixelation and is generally secure (I don't care if the NSA can tap it but no one else, especially over unencrypted wifi's). Open source is preferred but not required. Free or really really cheap is practically required. Also, since this is point to point, an i am a power user (and my gf as well), it can involve some manual setup to establish a point-to-point link. Any suggestions, Thanks.

  • What is your IT-department to staff ratio?

    - by Bart Silverstrim
    This is a topic that may be rather political but it related to system administration still...how many people do you have supporting your users in your IT department? We have three people supporting something near 1500 systems and around 2400 people and a recent question was raised about why we have long times to get systems replaced, repaired, work orders fulfilled, etc. along with the system admin duties of maintaining the servers (mail, proxy, filters, VOIP, wireless, backup, etc.) Does anyone have numbers on what the "best practices" average is of support people to employees in an organization? EDIT:...from some of the answers that are appearing I'm starting to feel depressed...

  • Live Folder: browser intent error

    - by MrSnowflake
    I'm trying to make a Live Folder with URIs. The intent I set to the Live Folder items is an Intent{Intent.ACTION_VIEW, Uri.parse(url)}. I have verified url is indeed http://www.google.com (for testing purposes). But when I click the item in the live folder I get an error message: "Application is not installed on your phone." I guess I'm missing something, but I have no idea how to make the browser launch.

  • Giving event control back to xaml/callee to access check/uncheck

    - by dovholuk
    Hi All, I've scoured the Internet but my search-foo must not work if it's out there cause I just can't find the proper search terms to get me the answer I am looking for. So I turn to the experts here as a last resort to point me in the right direction. What I'm trying to do is create a composite control of a text box and a list box but I want to allow the control consumer to decide what to do when say the checkbox is checked/unchecked and I just can't figure it out... Maybe i'm going about it all wrong. What I've done thus far is to: create a custom control that extends ListBox expose a custom DP named "Text" (for the Text box but it's not the important part) craft the generic.xaml so that the list items have a default ItemTemplate/DataTemplate inside the DataTemplate I'm trying to set the "Checked" or "Unchecked" events expose 'wrapper' events as DPs in the custom control that would get 'set' via the template when instatiated As soon as I try something like the following (inside generic.xaml): <DataTemplate> <...> <CheckBox Checked="{TemplateBinding MyCheckedDP}"/> <...> </DataTemplate> I get runtime exceptions, the designer - vs2010 - pukes out a LONG list of errors that are all very similar and nothing I do can make it work. I went so far as to try using the VisualTreeHelper but no magic combination I could find would work nor would it allow me to traverse the tree because when the OnApplyTemplate method fires the listbox items don't exist yet and aren't in the tree. So hopefully this all makes sense but if not please let me know and I'll edit the post for clarifications. Thanks to all for any pointers or thoughts... Like I said maybe I'm heading about it in the wrong way from the start... EDIT (Request for xaml) generic.xaml datatemplate: <DataTemplate > <StackPanel Orientation="Horizontal" > <local:FilterCheckbox x:Name="chk"> <TextBlock Text="{Binding Path=Display}" /> </local:FilterCheckbox> </StackPanel> </DataTemplate> usercontrol.xaml (invocation of custom control) <local:MyControl FancyName="This is the fancy name" ItemChecked="DoThisWhenACheckboxIsChecked" <-- this is where the consumer "ties" to the checkbox events ItemsSource="{Binding Source={StaticResource someDataSource}}" />

  • Float: left not showing up after a certain point.

    - by Bobby K
    http://test.jptgraphics.com/products?cat=APPAREL This works fine in Safari but shows incorrectly in the latest version of Firefox ( was fine in 3.5) and in some versions of IE. In the middle column the product thumbnails drop down below when the 'float: left;' parameter is used. It is as if it is being escaped by a tag from that point forward no 'float: left's work and all the items are centered moving forward.

The question is how to make it, I can only use ViewFlipper to flip to next screen or prev screen, how to manage these child views here? How to put them in my layout xml file?

  • P4 vs. i3/i5 *T in power consumption and performance [migrated]

    - by Walter Zomb
    I am running an Intel P4 prescott with HT on my home server (linux file server on encrypted disks on software-RAID5 and virtualisation host for three further machines). The performance for this purpose is really okay. When the system is idle it consumes about 140W power. I am considering buying a new mainboard for an e.g. Intel i3-2100T or an Intel i5-2390T. Both are low power CPUs with a TDP about 40W. Has anyone experiences how much power a recent mainboard with one of these CPUs an 3-4 'green-energy' disks (6W each) consumes? Do I get underneath the 100W threshold? What's about the performance of these low power CPUs? Are they comparable to an Intel P4 with HT? regards, walter

  • How do you manipulate form values based off local input?

    - by dmanexe
    I have a form that has a series of check boxes and some line items have a text input next to them that defines quantity of the item. <input type="checkbox" name="measure[][input]" value="<?=$item->id?>"> <input class="item_mult" type="text" name="measure[][input]" /> What is the best way to capture the integer from the input field and have it correspond to the check box so I can use it to calculate the total later on?

  • What files should be excluded from a complete Windows backup?

    - by tro
    I'm starting to use CrashPlan to backup my Win 7 PC. I've got it writing to my external HD (for quick local restores) and to CrashPlan Central (for offsite storage). I'd like to backup my entire C:\ drive (the only partition) in a way that: Preserves all of my installed software and configuration, but Avoids backing up log files and other ephemeral / temporary files that are regenerated during normal operation of the OS. Which files and/or directories should I be excluding from backups? I'd like to make this a community wiki, so that we could all contribute towards a definitive list. Here's a list of regular expressions identifying the directories and files that CrashPlan excludes on Windows by default listed at http://support.crashplan.com/doku.php/articles/admin_excludes: .*/(?:42|\d{8,})/(?:cp|~).* (?i).*/CrashPlan.*/(?:cache|log|conf|manifest|upgrade)/.* .*\.part .*/iPhoto Library/iPod Photo Cache/.* .*\.cprestoretmp.* *\.rbf :/Config\\.Msi.* .*/Google/Chrome/.*cache.* .*/Mozilla/Firefox/.*cache.* .*\$RECYCLE\.BIN/.* .*/System Volume Information/.* .*/RECYCLER/.* .*/I386.* .*/pagefile.sys .*/MSOCache.* .*UsrClass\.dat\.LOG .*UsrClass\.dat .*/Temporary Internet Files/.* (?i).*/ntuser.dat.* .*/Local Settings/Temp.* .*/AppData/Local/Temp.* .*/AppData/Temp.* .*/Windows/Temp.* (?i).*/Microsoft.*/Windows/.*\.log .*/Microsoft.*/Windows/Cookies.* .*/Microsoft.*/RecoveryStore.* (?i).:/Config\\.Msi.* (?i).*\\.rbf .*/Windows/Installer.* Other excludes: .*\.(class|obj) .*/hiberfil.sys (?i).*\.tmp (?i).*/temp/ (?i).*/tmp/ .*Thumbs\.db .*/Local Settings/History/ .*/NetHood/ .*/PrintHood/ .*/Cookies/ .*/Recent/ .*/SendTo/

  • iTunes command+tab does not bring main window the foreground after command+h

    - by ecoffey
    Related to : Cmd-Tab does not bring iTunes to foreground There people claim that command+h will continue to work, but the behavior I'm seeing is: Launch a full screen Terminal instance (or anything else really) Launch a fresh iTunes command+h to hide it command+tab back to iTunes, this works and the main app window is given focus command+tab to Terminal command+tab to iTunes What I expect to happen: the main iTunes window is brought to the foreground and given focus. What does happen: The application menu bar shows iTunes, but an additional command+` is needed to bring the main app to foreground. I thought it might have been related to a Chrome interaction, since I'm usually commmand+tabbing between my browser and everything else, but that does not seem to be the case. I do have two "plugins" running: last.fm scrobbler Alfred app mini itunes player interface Not sure if either of those create some phantom window or something that is mixing something up. Versions of stuff: OS X: 10.6.5 iTunes: 10.1.1 (4) last.fm: can't find it, but it's recent Alfred: 0.8 (89) So after that big long rant, anyone else seeing this behavior?

  • What virtual machine software for fail-over and snapshots?

    - by consolibyte
    We're looking to virtualize a few machines with the hope that we can: a) Take "snapshots" of a machine to use as backups b) Implement a system where if the software/hardware fails, we can quickly and easily load up an recent snapshot on new hardware and replace the failed machine with a new one. As always, cost is a concern- there's only 3 or 4 servers we're going to do this with, so we don't want to drop $50,000 on this. I'm confused by all of the different virtual machine offerings. Which one is does what I want, and does it easily?

  • alternatives to accessing google reader with oauth?

    - by Dustin Getz
    I'm really new to this oauth stuff. I want to access a user's google reader liked items feed. This blog says that oauth doesn't work (yet) with google reader. The working way seems to be to get the user's google credentials (email, password) directly, and login directly to google. This also gives me access to the rest of their services. Is there a better way, or must the user trust me with their google credentials?
