  • How to keep the function key locked on Lenovo E431?

    - by Bob
    For the Lenovo e431, how do you keep the function key locked. Right now, the default is when you press F1-F12, he multimedia controls are active. To get to the standard F1-F12, you have to hold down Fn+the function key. This used to available in bios, but for this laptop model, it no longer is available. You can press Fn+esc, and it locks it for that session, but when the computer reboots, this is reset back to the default. Is there a way so that the default is not the multimedia function keys, but just the standard, legacy function keys? Thanks.

  • HTG Explains: What Are the Sys Rq, Scroll Lock, and Pause/Break Keys on My Keyboard?

    - by Chris Hoffman
    Glance at your keyboard and chances are you’ll see a few keys you never use near the top-right corner – Sys Rq, Scroll Lock, and Pause / Break. Have you ever wondered what those keys are for? While these keys have been removed from some computer keyboards today, they’re still a common sight — even on new keyboards.

  • What is the "Apple" key and what key is it that is depicted as part of an upper case X?

    - by Marnix A. van Ammers
    I read in some answers about using the "Apple" + "Space bar" keys. Which is the "Apple" key? Also, I see in my Mac OS X Safari menu bar that to open the download window I can use a 3 key combination. The last of the 3 keys are the Command key (depicted with a clover leaf symbol) and the 'L' key. The first key is the one I don't see anywhere. It is depicted by a symbol that looks to me like an upper case 'X' with most of the forward slash part removed. What key is that? OK, just discovered by trial and error that it must be a symbol for the "option" key. What is that symbol called and why is it not on the keyboard?

  • strategy /insights for avoiding document content loss due to encryption

    - by pbernatchez
    I'm about to encourage a group of people to begin using S-Mime and GPG for digital signatures and encryption. I foresee a nightmare of encrypted documents which can no longer be recovered because of lost keys. The thorniest issue is archiving. The natural way to preserve privacy in an archive is to archive the encrypted document. But that opens us up to the risk of a lost key when time comes to unarchive a document, or a forgotten password. After all it will be a long way in the future. This would be equivalent to having destroyed the document. First thought is archiving keys with documents, but that still leaves the forgotten pass phrase. Archiving the passphrase too would be tantamount to archiving in the clear. No privacy. What approaches do you use? What insights can you offer on the issue?

  • Function key taken by another program, how to default it

    - by Milox
    Everytime I press the F11 key it opens up a browser window with the same URL. This happens anywhere I press it and I need this key to have it's default behavior because I use it to program on Visual Studio (Windows 7). Any ideas why this is happening and how to go back to default function keys?, I haven't installed anything that I remember can cause this behavior. This is a standard Dell desktop key board, no multimedia keys, like this one: Firing URL is http://argos:8080/Login.jsp?jsessionid=55rh3obsahm9m seems like one of our company's internal addresses but IT guys say they have no idea about it. I don't see any suspicious software that can be causing this.

  • is it possible to ssh into ubuntu server with keys and from another computer using password?

    - by Sandro Dzneladze
    I have ubuntu server at home, and I use SSH keys to log in via terminal from my laptop. Rarely, but mostly from work, I need to access this server, but I dont want to copy keys on my work laptop - Id rather just use plain password for that. So if I enable password log in from ssh config file, it will ask me password on my laptop too even though it contains keys, right? Is there a way to stop this behavior? Thanks.

  • Getting State of Modifier Keys Compact Framework

    - by CDM
    How can I get the state of a modifier key using VB.NET on the Compact Framework, in this case Windows Mobile 6.1. I want to be able to determine if the following keys are pressed or locked: Shift CTRL ALT and for the Psion Teklogix machines Orange Blue Although I may be able to work this out, if I can determine the others. I want to create my own on-screen indicator panel and want to poll the keys, not using events. Thanks Colin

  • iPhone - Merge keys in a NSArray (Objective-C)

    - by ncohen
    Hi everyone, I'm having troubles with arrays and keys... I have an array from my database: NSArray *elementArray = [[[menuArray valueForKey:@"meals"] valueForKey:@"recipe"] valueForKey:@"elements"] The problem here is that I would like all my elements of all my meals of all my menus in an array such that: [elementArray objectAtIndex:0] = my first element etc... In the example above, the elements are separated by the keys. How can I get that? Hope it's clear enough... Thanks

  • Storing secret keys on iPhone source and project resources

    - by hgpc
    Is storing secret keys (internal use passwords and such) on iPhone source code and project resources (such as plist files) secure? Obviously nothing is 100% secure, but can this information be extracted easily from an installed app? How do you recommend storing these keys to use them in the source code? Just in case, this question is not about storing user passwords.

  • Loop through multi-dimensional array and remove certain keys

    - by Webkungen
    Hi! I've got a nested tree structure which is based on the array below: Array ( [1] = Array ( [id] = 1 [parent] = 0 [name] = Startpage [uri] = 125 [basename] = index.php [child] = ) [23] = Array ( [id] = 23 [parent] = 0 [name] = Events [uri] = 0 [basename] = [child] = Array ( [24] = Array ( [id] = 24 [parent] = 23 [name] = Public news [uri] = 0 [basename] = [child] = Array ( [27] = Array ( [id] = 27 [parent] = 24 [name] = Add [uri] = 100 [basename] = news.public.add.php [child] = ) [28] = Array ( [id] = 28 [parent] = 24 [name] = Overview [uri] = 101 [basename] = news.public.overview.php [child] = ) ) ) [25] = Array ( [id] = 25 [parent] = 23 [name] = Private news [uri] = 0 [basename] = [child] = Array ( [29] = Array ( [id] = 29 [parent] = 25 [name] = Add [uri] = 67 [basename] = news.private.add.php [child] = ) [30] = Array ( [id] = 30 [parent] = 25 [name] = Overview [uri] = 68 [basename] = news.private.overview.php [child] = ) ) ) [26] = Array ( [id] = 26 [parent] = 23 [name] = Calendar [uri] = 0 [basename] = [child] = Array ( [31] = Array ( [id] = 31 [parent] = 26 [name] = Add [uri] = 69 [basename] = news.event.add.php [child] = ) [32] = Array ( [id] = 32 [parent] = 26 [name] = Overview [uri] = 70 [basename] = news.event.overview.php [child] = ) ) ) ) ) ) I'm looking for a function to loop (recursive?) through the array and remove some keys. I my system I can allow users to certain functions/pages and if I deny access to the whole "block" "Events", the array will look like this: Array ( [1] = Array ( [id] = 1 [parent] = 0 [name] = Startpage [uri] = 125 [basename] = index.php [child] = ) [23] = Array ( [id] = 23 [parent] = 0 [name] = Events [uri] = 0 [basename] = [child] = Array ( [24] = Array ( [id] = 24 [parent] = 23 [name] = Public news [uri] = 0 [basename] = [child] = ) [25] = Array ( [id] = 25 [parent] = 23 [name] = Private news [uri] = 0 [basename] = [child] = ) [26] = Array ( [id] = 26 [parent] = 23 [name] = Calendar [uri] = 0 [basename] = [child] = ) ) ) ) As you can see above, the whole "block" "Events" is useless right now, becuase there is no page associated with each option. So I need to find all "keys" where "basename" is null AND where child is not an array or where the array is empty and remove them. I found this function when searching the site: function searchAndDestroy(&$a, $key, $val){ foreach($a as $k = &$v){ if(is_array($v)){ $r = searchAndDestroy($v, $key, $val); if($r){ unset($a[$k]); } }elseif($key == $k && $val == $v){ return true; } } return false; } It can be used to remove a key any where in the array, but only based in one thing, for example remove all keys where "parent" equals "23". But I need to find and remove (unset) all keys where "basename" is null AND where child isn't an array or where the array is empty. Can anyone help me out and possibly tweak the function above? Thank you,

  • Is it possible to use pure Encoding and Decoding keys in asymmetric cryptography instead of private

    - by macropas
    Is it possible to use pure Encoding and Decoding keys instead of private and public keys? As I know in .Net asymmetric RSA implementation private key RSAParameters parameters = (new RSACryptoServiceProvider()).ExportParameters(true) is a superset of public key. And using private key we can both encode and decode our data. But I need key only for decoding data. How to do it? I experimented on nulling RSAParameters fields, but RSACryptoServiceProvider object can't import such parameters.

  • What's faster Model.get(keys) or Model.get_by_id(ids, parent=None)

    - by WooYek
    I'm wondering is there a difference in terms of computing cost for the Model.get(keys) and Model.get_by_id(ids, parent=None) methods? Is there a server side computing advantage of using numeric id's over encoded string keys, or other way around? How big is the difference? PS. Sorry, if it's a dupe. I'm sure I read an article about it, but I cannot find it now.

  • deployment public keys

    - by hyperboreean
    How do you guys deploy your code on your servers? I am using Fabric and Python and I would like a more automated way of pulling code from the repository through the use of public keys, but without any ops or manual intervention to set up the public keys. Are you storing them in the code as text or in a database and generate the pk file on the fly?

  • Can't change the layout of alternatives keys show on android keyboard

    - by Tebam
    I want to change the default layout which Android uses for show the alternative keys when performs a long-press on a key. Keys have an attribute "android:popupKeyboard" used for define the layout of the alternative key list (which could be a Keyboard reference) but when I use it the Android's default layout still appears. Is possible to change or override this layout?

  • C# Get Keys from a Dictionary<string, Stream>

    - by alex
    Suppose I have a Dictionary like so: Dictionary<string, Stream> How can I get a list (or IEnumerable or whatever) of JUST the Keys from this dictionary? Is this possible? I could enumerate the dictionary, and extract the keys one by one, but I was hoping to avoid this. In my instance, the Dictionary contains a list of filenames (file1.doc, filex.bmp etc...) and the stream content of the file from another part of the application.
