• How can I use my keyboard as a mouse?

  - by Michael Durrant

  I'm using my keyboard more and more these days for basic command line stuff, vim editing, alt-tab window switching and the like. Q) How can I use my number pad keys to move the cursor around on the screen without using the mouse? I looked to try and install btnx as mentioned by others but it doesn't seem to exist anymore as an available package I also tried shift-numlock as mentioned by another but that didn't work either (just turns numlock on/off).

• Assigning shortcuts (accelerators) to Nautilus 3

  - by abruski

  I want to assign some shortcuts to menu actions in Nautilus 3.2.1 running under Ubuntu 11.10. I followed the steps shown here How do you create a "new document" keyboard shortcut? but it did not work for me. Switched to gnome classic so I can get the normal menu, hovered over the desired action pressed the desired keys but nothing happened (restarted nautilus, re-logged and nothing). Any suggestions or ideas on how to assign custom shortcuts to actions in Nautilus 3

• Choose identity from ssh-agent by file name

  - by leoluk

  Problem: I have some 20-30 ssh-agent identities. Most servers refuse authentication with Too many failed authentications, as SSH usually won't let me try 20 different keys to log in. At the moment, I am specifying the identity file for every host manually, using the IdentityFile and the IdentitiesOnly directive, so that SSH will only try one key file, which works. Unfortunately, this stops working as soon as the original keys aren't available anymore. ssh-add -l shows me the correct paths for every key file, and they match with the paths in .ssh/config, but it doesn't work. Apparently, SSH selects the indentity by public key signature and not by file name, which means that the original files have to be available so that SSH can extract the public key. There are two problems with this: it stops working as soon as I unplug the flash drive holding the keys it renders agent forwarding useless as the key files aren't available on the remote host Of course, I could extract the public keys from my identity files and store them on my computer, and on every remote computer I usually log into. This doesn't looks like a desirable solution, though. What I need is a possibility to select an identity from ssh-agent by file name, so that I can easily select the right key using .ssh/config or by passing -i /path/to/original/key, even on a remote host I SSH'd into. It would be even better if I could "nickname" the keys so that I don't even have to specify the full path.

• Navigating Libgdx Menu with arrow keys or controller

  - by Phil Royer

  I'm attempting to make my menu navigable with the arrow keys or via the d-pad on a controller. So Far I've had no luck. The question is: Can someone walk me through how to make my current menu or any libgdx menu keyboard accessible? I'm a bit noobish with some stuff and I come from a Javascript background. Here's an example of what I'm trying to do: http://dl.dropboxusercontent.com/u/39448/webgl/qb/qb.html For a simple menu that you can just add a few buttons to and it run out of the box use this: http://www.sadafnoor.com/blog/how-to-create-simple-menu-in-libgdx/ Or you can use my code but I use a lot of custom styles. And here's an example of my code: import aurelienribon.tweenengine.Timeline; import aurelienribon.tweenengine.Tween; import aurelienribon.tweenengine.TweenManager; import com.badlogic.gdx.Game; import com.badlogic.gdx.Gdx;

• Generating Entity Keys

  - by David Veeneman

  I have run into my first dissapointment with Entity Framework 4. It turns out that SQL CE, when used with EF4, does not support autogenerated primary keys. I get a System.Data.UpdateException from OnjectContext.SaveChanges() with this message: Server-generated keys and server-generated values are not supported by SQL Server Compact. So, now I have to manually generate keys for my entities. Assuming I want to use auto-incremented integer keys, what is the best way to go about generating and keeping track of the keys when using Entity Framework? Thanks for your help.

• Compound dictionary keys

  - by John Keyes

  I have a particular case where using compound dictionary keys would make a task easier. I have a working solution, but feel it is inelegant. How would you do it? context = { 'database': { 'port': 9990, 'users': ['number2', 'dr_evil'] }, 'admins': ['[email protected]', '[email protected]'], 'domain.name': 'virtucon.com' } def getitem(key, context): if hasattr(key, 'upper') and key in context: return context[key] keys = key if hasattr(key, 'pop') else key.split('.') k = keys.pop(0) if keys: try: return getitem(keys, context[k]) except KeyError, e: raise KeyError(key) if hasattr(context, 'count'): k = int(k) return context[k] if __name__ == "__main__": print getitem('database', context) print getitem('database.port', context) print getitem('database.users.0', context) print getitem('admins', context) print getitem('domain.name', context) try: getitem('database.nosuchkey', context) except KeyError, e: print "Error:", e Thanks.

• C# Count registry keys existing using a partial value

  - by cheeseman

  Microsoft.Win32.RegistryKey registryPath = Microsoft.Win32.Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Wow6432Node\Testing"); Microsoft.Win32.RegistryKey entryKey = registryPath.OpenSubKey("Entry Point"); I have a lot of keys in Testing, in the format: "Entry Point 011", "Entry Point 123" - so Entry Point with random numbers after it. Would I be able to search the registryPath variable above and get a count of the number of keys containing the "Entry Point" keyword? Assuming that there are also other keys existing without this keyword. At the moment I have been using a for loop and looping for all possible combinations to get a count of all the keys, checking if the key exists or not, but as there are keys as high as "Entry Point 9000" having a for loop execute 9000 times is very inefficient. for (int i = 0; i <= highestEntryPointValue; i++) { Microsoft.Win32.RegistryKey entryKey = steamApps64.OpenSubKey("Entry Point " + Convert.ToString(i)); if (entryKey != null) { count++; } }

• 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.

• Problem with shared ssh keys

  - by warren

  Following the process I've used in other environments (http://www.trilug.org/pipermail/trilug/Week-of-Mon-20080602/054712.html), I've tried setting-up shared keys between my Mac and my CentOS 4 webserver. I've seen the same problem with my older Ubuntu 7.10 workstation trying to connect via keys to the same webserver. I have tried both dsa and rsa keytypes (sshkeygen -t <type>). The sshd_config file on my webserver seems to be allowing key-based logins: RSAAuthentication yes PubkeyAuthentication yes AuthorizedKeysFile .ssh/authorized_keys And my .ssh/authorized_keys has my dsa and rsa keys added. Where should I be looking for what to change next to make key-based logins "Just Work™"? Is it related to the line #UseDNS yes and sshd is trying to do a reverse-lookup on my IP, but cannot because it's NAT'd?

• SSH keys fail for one user

  - by Eli

  I just set up a new Debian server. I disabled root SSH and password auth, so you've gotta use a key file. For my primary user, everything works exactly as expected. I used ssh-keygen -t dsa and got myself a public and private key. Put one in authorized keys, put the other in a pem file locally. I wanted to create a user that I can deploy things with, so I did basically the same process. I addusered it, made a .ssh folder, ran ssh-keygen -t dsa (I also tried RSA), put the keys in their appropriate locations. No luck. I'm getting a Permission denied (publickey) error. When I use the exact same keys as the account that works, same error. When I enable password authentication, I can log in via SSH with the password. How do I debug this?

• Using ctrl-arrow keys with PuTTY and screen

  - by kbosak

  I searched and couldn't find a solution for this anywhere. I'm using PuTTY from Windows to connect to various servers where I run bash and screen. It seems bash works fine with ctrl-arrow keys to jump word-to-word on the command line but within screen it's not working. Not in screen, ctrl-left sends "^[OC and ctrl-right is "^[OD". Within screen I instead get "^[[C" and "^[[D", which appears to be the codes for just the left/right arrow keys. Is there any way to get screen to recognize ctrl-arrow keys when using PuTTY? (FYI, I don't remember having this problem when using gnu-terminal in linux instead of PuTTY).

• arrow keys stop working to scroll pages

  - by Delirium tremens

  Sometimes, the arrow keys stop working to scroll pages. Sometimes, in Firefox - Tools - Options - Advanced - Accessibility - General, the first checkbox, about using arrow keys to scroll pages, appears checked and some other times, unchecked. When it's unchecked, I check it. When it's checked, I keep it checked. In both times, I click OK. Then, the arrow keys restart working to scroll pages. I'm having to do it all the time. What should I do?

• Keyboard doesn't let me press certain keys at the same time

  - by kitchen

  I'm not sure how to word the problem other than I can't use certain keys at the same time. For example, when playing games that require you to use the arrow keys to move and jump/duck I am unable to move to the left and jump (left arrow + up arrow) at the same time. As a result, I don't play many games when I get to a point where the jumps and what not are too far. This happens with other keys as well. In FPS I am unable to hold W to move forward and hit 2 to select my secondary weapon. Some information that might help you: I am using Windows 7 64-bit I am using a Micro Innovations KB565BL keyboard How can I fix this?

• Microsoft Basic Office 2007 Activation Keys won't work after re-installing on my Laptop

  - by Rolnik

  So, I've upgraded my hard-drive on my laptop, and proceeded to grab my trusty copper-faced Official MS Office disk to do an install. I have three licenses with the fancy green-blue paper that identifies the license keys. Problem is, that for each of these license keys, when the Office 2007 software asks that I enter the "Product Key" it states: The key is incorrect. Verify that you have the correct key, and then retype it Why would Microsoft want to inhibit/prohibit re-installs on the same machine that the software was initially installed to? Incidentally, the same goofy error happens with each of the three valid product key (activation keys) that I enter.

• XKB - remap arrow keys and preserve shift behaviour to select text

  - by dgirardi

  I realize arrow key remapping is an old problem, however I cannot seem to find a good solution that lets me select text with SHIFT + remapped keys as I would do with the vanilla arrow keys. For instance, if I remap Caps Lock to ISO_Level3_Shift and set xkb_symbols to read either key <AC08> { [ k, K , Down, Down] }; or key <AC08> { type="THREE_LEVEL", [ k, K , Down ] }; Pressing Shift+CapsLock+K will behave exactly as CapsLock+K (while Shift+Down behaves differently from Down alone). I had somewhat more success using higher level macro utilities and generating keyboard events (i.e. generate both the shift and the arrow keypresses); hoever that approach has a whole set of different problems - often the UI response to a simulated keypress is different from the "real" keypress, and there are performance problems as well - I can type faster than the thing can handle. Tl;dr; how can you shift-select using remapped arrow keys under X?

• Keeping Private SSH Keys Safe

  - by Carmen

  I have a central server where I stored all the private ssh keys to the different machines that I want to ssh to. Currently, only sysadmins have access to this 'central' server. Given the above scenario, I like to ask the following questions: How do you protect your private ssh keys? I read about ssh-agent but I am not sure how to use it or if it can be used in this situation. If a sysadmin leaves and he copies all the private ssh keys, then he has access to all the servers. How do you deal with this situation?

• Remapping special keys on the keyboard

  - by thedude

  Hey there. I just bought a new keyboard today, and to my suprise it doesn't include "Next/Previus track" keys, although it has other media keys. It also has useless keys like "Home" which brings up the webbrowser. Or well, it's not actually the "Home" key, it's a special key on the keyboard with a house on it - no idea what it's called. Anyway, so i'd like to remap the "House" key to "Next track". I've tried three different remapping programs now and none of them seem to be working. I think the real problem is that it's a special key, so it's not included in any keyboard remapping applications. The keyboard is a Logitech, can't seem to find the exact model though. Any tips?

• some keyboard keys not working properly

  - by surfmadpig

  I'm using Windows 7. All of a sudden, a couple of hours ago, this happened: My keyboard number keys [above the letters] stopped working properly, both as numbers and as symbols. Only 5 and 6 are functional. Also, I've noticed that the End key isn't working either, and perhaps a couple more from that group. I'm pretty sure it has something to do with those evil Sticky Keys/Filter Keys/ whatever those ease of access things are, BUT I've turned off all the ease of access keyboard options and nothing has changed. Is it possible that something is still turned on while I unchecked it? Are the on/off checkboxes to control WHEN it happens or IF it happens? I also tried rebooting and uninstalling/reinstalling keyboard from device manager, to no avail. It's certainly a software issue and not a hardware issue, as I've tried another keyboard and the problem persists. And, predictably enough, it's annoying. Any ideas?

• Keyboard layout to shift wasd keys

  - by Joel Coehoorn

  I like to play video games on my computer. One of the things that bugs me, though, is how the wasd keys became the standard movement keys in first person shooters and mmorpgs. To me, esdf makes a lot more sense, because that matches your normal hand placement for typing. "Fixing" that layout is always the first thing I do when installing a new game. Sadly, this is often a pain in the neck, and some games won't let you do it at all. Is there an alternative keyboard layout you can install that will just switch these around, so the wasd keys fall in the esdf positions? And is low-level enough two work with DirectX/DirectInput, perhaps that works with the language bar for easy swapping back and forth?

• Windows 7 CD keys, are they interchangable?

  - by unixman83

  I am talking about during installation. Using regular licensing, not volume licensing. Amongst OSes of the same class, are CD keys interchangeable or are they locked to a specific subset of CDs? In other words: If I have 10 legally purchased copies of Windows 7 Professional, can I throw out the discs for all but one? And all the CD keys will work? UPDATE: How about for service packs (when they come out). If I have Windows 7 Professional SP1 and a Windows 7 RTM original? Do they change CD keys between service packs?

• How to use cursor keys to switch buffers in GNU screen

  - by suvayu

  I want to use cursor keys or cursor keys with a modifier like Ctrl to switch between screen buffers (e.g. C-a [arrow] or C-a C-[arrow]). So far I have tried settings like the ones below with no success. bind \224\115 prev bind \224\116 next bindkey -d ^[[1;5D prev bindkey -d ^[[1;5C next They are either ignored or behave unexpectedly (the second one). I am also not sure how to specify the keys. To get the characters, I either used C-v to quote them in bash, or tried to look-up on the Internet (e.g. http://ascii-table.com/ansi-escape-sequences.php). Any idea how I can achieve this key binding?

• SQL SERVER – Disable Clustered Index and Data Insert

  - by pinaldave

  Earlier today I received following email. “Dear Pinal, [Removed unrelated content] We looked at your script and found out that in your script of disabling indexes, you have only included non-clustered index during the bulk insert and missed to disabled all the clustered index. Our DBA[name removed] has changed your script a bit and included all the clustered indexes. Since our application is not working. When DBA [name removed] tried to enable clustered indexes again he is facing error incorrect syntax error. We are in deep problem [word replaced] [Removed Identity of organization and few unrelated stuff ]“ I have replied to my client and helped them fixed the problem. What really came to my attention is the concept of disabling clustered index. Let us try to learn a lesson from this experience. In this case, there was no need to disable clustered index at all. I had done necessary work when I was called in to work on tuning project. I had removed unused indexes, created few optimal indexes and wrote a script to disable few selected high cost indexes when bulk insert (and similar) operations are performed. There was another script which rebuild all the indexes as well. The solution worked till they included clustered index in disabling the script. Clustered indexes are in fact original table (or heap) physically ordered (any more things – not scope of this article) according to one or more keys(columns). When clustered index is disabled data rows of the disabled clustered index cannot be accessed. This means there will be no insert possible. When non clustered indexes are disabled all the data related to physically deleted but the definition of the index is kept in the system. Due to the same reason even reorganization of the index is not possible till the clustered index (which was disabled) is rebuild. Now let us come to the second part of the question, regarding receiving the error when clustered index is ‘enabled’. This is very common question I receive on the blog. (The following statement is written keeping the syntax of T-SQL in mind) Clustered indexes can be disabled but can not be enabled, they have to rebuild. It is intuitive to think that something which we have ‘disabled’ can be ‘enabled’ but the syntax for the same is ‘rebuild’. This issue has been explained here: SQL SERVER – How to Enable Index – How to Disable Index – Incorrect syntax near ‘ENABLE’. Let us go over this example where inserting the data is not possible when clustered index is disabled. USE AdventureWorks GO -- Create Table CREATE TABLE [dbo].[TableName]( [ID] [int] NOT NULL, [FirstCol] [varchar](50) NULL, CONSTRAINT [PK_TableName] PRIMARY KEY CLUSTERED ([ID] ASC) ) GO -- Create Nonclustered Index CREATE UNIQUE NONCLUSTERED INDEX [IX_NonClustered_TableName] ON [dbo].[TableName] ([FirstCol] ASC) GO -- Populate Table INSERT INTO [dbo].[TableName] SELECT 1, 'First' UNION ALL SELECT 2, 'Second' UNION ALL SELECT 3, 'Third' GO -- Disable Nonclustered Index ALTER INDEX [IX_NonClustered_TableName] ON [dbo].[TableName] DISABLE GO -- Insert Data should work fine INSERT INTO [dbo].[TableName] SELECT 4, 'Fourth' UNION ALL SELECT 5, 'Fifth' GO -- Disable Clustered Index ALTER INDEX [PK_TableName] ON [dbo].[TableName] DISABLE GO -- Insert Data will fail INSERT INTO [dbo].[TableName] SELECT 6, 'Sixth' UNION ALL SELECT 7, 'Seventh' GO /* Error: Msg 8655, Level 16, State 1, Line 1 The query processor is unable to produce a plan because the index 'PK_TableName' on table or view 'TableName' is disabled. */ -- Reorganizing Index will also throw an error ALTER INDEX [PK_TableName] ON [dbo].[TableName] REORGANIZE GO /* Error: Msg 1973, Level 16, State 1, Line 1 Cannot perform the specified operation on disabled index 'PK_TableName' on table 'dbo.TableName'. */ -- Rebuliding should work fine ALTER INDEX [PK_TableName] ON [dbo].[TableName] REBUILD GO -- Insert Data should work fine INSERT INTO [dbo].[TableName] SELECT 6, 'Sixth' UNION ALL SELECT 7, 'Seventh' GO -- Clean Up DROP TABLE [dbo].[TableName] GO I hope this example is clear enough.
