What gaming keyboard(s) will work with Ubuntu?

- by belacqua

I've been looking at gaming keyboards to use on Ubuntu system. Microsoft has a few popular ones (e.g., Sidewinder X4, X6), but the programmable function keys appear to be unusable without the Windows software. (Though here's a post from someone who has a more recent project that uses usbmon and xdotool to add functions to some keys.) Another choice in my budget is the Cyborg V.05. It seems about right for my needs, but I would be depressed having a bunch of useless, nonprogrammable keys on it. Logitech has some models (e.g., the Logitech G110), though again I expect that the extensive macro capabilities (which I don't need) would be lost under Linux. There's a project called g15tools which has some code to work with older Logitech gaming models, but I don't know what the current status is. Last entry there was in March 2010. There are also a number of very old posts around the internet with regard to the Logitech G11 and G15. Compatibility with the current keyboards, Ubuntu version, and Linux kernel are suspect. I'm in the U.S., and so it appears that few of the Roccat keyboards are available, and they're over-priced. Support might be OK for these, though -- there's a short Phoronix article about Roccat improving their Linux support, and there's also a project and webpage for "Using Roccat Hardware with Linux". Honestly, the only feature I have to have is good backlighting for the keys, and if it's not wired (which is fine), the wireless capability should function. I could probably live with dead function keys, as long as they weren't in places that would interfere with things like Unity/compiz shortcuts. Any experience or suggestions? I've not seen much to inspire confidence with programmable/macro keys. There is a thread (with no solutions) on the Sidewinder X4 on ubuntuforums here. I'm also considering the Logitech Illuminated Keyboard as a possibility, even though it's not specifically a gaming keyboard. It is backlit, and it's supposed to be a nice keyboard.

How can I enable special Fn-Keys on my on lenovo s206 (e.g. touchpad on/off)?

- by user2546783

I can turn the touchpad off in the mouse settings, but two things won't work: The "disable while typing" option The standard on/off button for the touch pad won't work (it's the one with the little touchpad symbol crossed off, on the F6 key). I've tried any of the following combinations: Alt+F6 Fn+F6 Ctrl+F6 Super+F6 Shift+F6. Almost all the other keys of that kind work, like brightness control, volume control, Wifi toggle, but this one and the mic off and camera off won't work.

What are the right reverse PTR, domain keys, and SPF settings for two domains running the same appli

- by James A. Rosen

I just read Jeff Atwood's recent post on DNS configuration for email and decided to give it a go on my application. I have a web-app that runs on one server under two different IPs and domain names, on both HTTP and HTTPS for each: <VirtualHost *:80> ServerName foo.org ServerAlias www.foo.org ... </VirtualHost> <VirtualHost 1.2.3.4:443> ServerName foo.org ServerAlias www.foo.org </VirtualHost> <VirtualHost *:80> ServerName bar.org ServerAlias www.bar.org ... </VirtualHost> <VirtualHost 2.3.4.5:443> ServerName bar.org ServerAlias www.bar.org </VirtualHost> I'm using GMail as my SMTP server. Do I need the reverse PTR and SenderID records? If so, do I put the same ones on all of my records (foo.org, www.foo.org, bar.org, www.bar.org, ASPMX.L.GOOGLE.COM, ASPMX2.GOOGLEMAIL.COM, ..)? I'm pretty sure I want the domain-keys records, but I'm not sure which domains to attach them to. The Google mail servers? foo.org and bar.org? Everything?

How can I restore the registry keys from another C drive? (Windows 7 64bit)

- by graham3d

I ran Uniblue registry booster on my system which was working fine. It did a full back up of the registry keys. Now I cannot boot from that disk. I also cannot get into the BIOS! To restore the registry I have to run Uniblue registry booster from within windows. I cannot get there. I can boot up on another C drive, and can see the files on the drive with the problem. Is there any way I can find the Registry Booster backup files and restore it from the other disk? Or find the registry backup and upload it into the registry so I can boot off the other disk again? Or, Can I do a windows repair from the other disk? NB: not getting in to the bios means I cannot boot off the CD/DVD! (I can use the DVD drive from within windows) Any ideas? I do not want to reinstall everything yet again, it takes about 6 hours.

How do I get the F1-F12 keys to switch screens in gnu screen in cygwin when connecting via SSH?

- by Mikey

I'm connecting to a desktop running cygwin via SSH from the terminal app in Mac OS X. I have already started screen on the cygwin side and can connect to it over the SSH session. Furthermore, I have the following in the .screenrc file: bindkey -k k1 select 1 # F1 = screen 1 bindkey -k k2 select 2 # F2 = screen 2 bindkey -k k3 select 3 # F3 = screen 3 bindkey -k k4 select 4 # F4 = screen 4 bindkey -k k5 select 5 # F5 = screen 5 bindkey -k k6 select 6 # F6 = screen 6 bindkey -k k7 select 7 # F7 = screen 7 bindkey -k k8 select 8 # F8 = screen 8 bindkey -k k9 select 9 # F9 = screen 9 bindkey -k F1 prev # F11 = prev bindkey -k F2 next # F12 = next However, when I start multiple windows in screen and attempt to switch between them via the function keys, all I get is a beep. I have tried various settings for $TERM (e.g. ansi, cygwin, xterm-color, vt100) and they don't really seem to affect anything. I have verified that the terminal app is in fact sending the escape sequence for the function key that I'm expecting and that my bash shell (running inside screen) is receiving it. For example, for F1, it sends the following (hexdump is a perl script I wrote that takes STDIN in binmode and outputs it as a hexadecimal/ascii dump): % hexdump [press F1 and then hit ^D to terminate input] 00000000: 1b4f50 .OP If things were working correctly, I don't think bash should receive the escape sequence because screen should have caught it and turned it into a command. How do I get the function keys to work?

Mapping composite foreign keys in a many-many relationship, with overlapping components.

- by Kirk Broadhurst

I have a Page table and a View table. There is a many-many relationship between these two via a PageView table. Unfortunately all of these tables need to have composite keys (for business reasons). Page has a primary key of (PageCode, Version), View has a primary key of (ViewCode, Version). PageView obviously enough has PageCode, ViewCode, and Version. The FK to Page is (PageCode, Version) and the FK to View is (ViewCode, Version) Makes sense and works, but when I try to map this in Entity framework I get Error 3021: Problem in mapping fragments...: Each of the following columns in table PageView is mapped to multiple conceptual side properties: PageView.Version is mapped to (PageView_Association.View.Version, PageView_Association.Page.Version) So clearly enough, EF is having a complain about the Version column being a common component of the two foreign keys. Obviously I could create a PageVersion and ViewVersion column in the join table, but that kind of defeats the point of the constraint, i.e. the Page and View must have the same Version value. Has anyone encountered this, and is there anything I can do get around it? Thanks!

Why would memcached refuse to store data with some keys ?

- by Pierre

Hello, I use the memcache extension for python, and I have a very strange problem. Memcached refuses to store the exact same data with some keys, and succeeds in caching some others. >>> conn.set('138b9c95d693760840aab85ee5591d2', 'test'); True >>> conn.set('138b9c95d693760840aab85ee5591d3', 'test'); 0 >>> conn.set('138b9c95d693760840aab85ee5591d4', 'test'); True >>> conn.set('138b9c95d693760840aab85ee5591d5', 'test'); 0 >>> conn.set('138b9c95d693760840aab85ee5591d6', 'test'); True >>> conn.set('138b9c95d693760840aab85ee5591d7', 'test'); 0 >>> conn.set('138b9c95d693760840aab85ee5591d8', 'test'); True >>> conn.set('138b9c95d693760840aab85ee5591d9', 'test'); True >>> conn.set('138b9c95d693760840aab85ee5591e0', 'test'); True >>> conn.set('138b9c95d693760840aab85ee5591e1', 'test'); True I don't really understand. I should add that I use the version 1.40 of the memcache module with memcached 1.2.8 running on Ubuntu Server 9.10. I restarted the memcached daemon, same result, with the same keys. Thanks. Update: I upgraded memcached to version 1.4.2, packaged on lucid repos, with the exact same result.

Database design and foreign keys: Where should they be added in related tables?

- by Carvell Fenton

I have a relatively simple subset of tables in my database for tracking something called sessions. These are academic sessions (think offerings of a particular program). The tables to represent a sessions information are: sessions session_terms session_subjects session_mark_item_info session_marks All of these tables have their own primary keys, and are like a tree, in that sessions have terms, terms have subjects, subjects have mark items, etc. So each on would have at least its "parent's" foreign key. My question is, design wise is it a good idea to include the sessions primary key in the other tables as a foreign key to easily select related session items, or is that too much redundency? If I include the session foreign key (or all parent foreign keys from tables up the heirarchy) in all the tables, I can easily select all the marks for a session. As an example, something like SELECT mark FROM session_marks WHERE sessionID=... If I don't, then I would have to combine selects with something like WHERE something IN (SELECT... Which approach is "more correct" or efficient? Thanks in advance!

jQuery: How to use modifier keys on form submit?

- by Svish

Say I have a form that looks like this: [ Animal name input field ] Add button If I type a name and hit enter, an animal with the given name is added to a table. Works fine. What I would like now is to call the current way of working "quick add" and add a new feature called "slow add", which I am not quite sure how to do. Basically what I want is that if for example the shift key is held down when enter or the button is clicked, I want the form submit method to do something slightly different. In my case I want it to open up a form where more details on the animal can be added before it is added to the table. Problem is I'm not quite sure how to do this. I have tried add a FireBug console.info(eventData) in my current submit function and I have found that the eventData contains an altKey, shiftKey and controlKey property, but they are always undefined even when I hold those keys down. So, does anyone know how I can do something special in my submit handler when certain modifier keys were pressed when the form was submitted?

Processing a resultset to look up foriegn keys (and poulate a new table!)

- by Gilly

Hi, I've been handed a dataset that has some fairly basic table structures with no keys at all. eg {myRubishTable} - Area(varchar),AuthorityName(varchar),StartYear(varchar),StartMonth(varcha),EndYear(varchar),EndMonth(varchar),Amount(Money) there are other tables that use the Area and AuthorityName columns as well as a general use of Month and Years so I I figured a good first step was to pull Area and Authority into their own tables. I now want to process the data in the original table and lookup the key value to put into my new table with foreign keys which looks like this. (lookup Tables) {Area} - id (int, PK), name (varchar(50)) {AuthorityName} - id(int, PK), name(varchar(50) (TargetTable) {myBetterTable} - id (int,PK), area_id(int FK-Area),authority_name_id(int FK-AuthorityName),StartYear (varchar),StartMonth(varchar),EndYear(varchar),EndMonth(varchar),Amount(money) so row one in the old table read MYAREA, MYAUTHORITY,2009,Jan,2010,Feb,10000 and I want to populate the new table with 1,1,1,2009,Jan,2010,Feb,10000 where the first '1' is the primary key and the second two '1's are the ids in the lookup tables. Can anyone point me to the most efficient way of achieving this using just SQL? Thanks in advance Footnote:- I've achieved what I needed with some pretty simple WHERE clauses (I had left a rogue tablename in the FROM which was throwing me :o( ) but would be interested to know if this is the most efficient. ie SELECT [area].[area_id], [authority].[authority_name_id], [myRubishTable].[StartYear], [myRubishTable].[StartMonth], [myRubishTable].[EndYear], [myRubishTable].[EndMonth], [myRubishTable].[Amount] FROM [myRubishTable],[Area],[AuthorityName] WHERE [myRubishTable].[Area]=[Area].[name] AND [myRubishTable].[Authority Name]=[dim_AuthorityName].[name] TIA

PHP - Pull out array keys that have matching values?

- by MAZUMA

Is there a way to look inside an array and pull out the keys that have keys with matching values? Questions like this have been asked, but I'm not finding anything conclusive. So if my array looks like this Array ( [0] => Array ( [title] => Title 1 [type] => [message] => ) [1] => Array ( [title] => Title 2 [type] => [message] => ) [2] => Array ( [title] => Title 3 [type] => [message] => ) [3] => Array ( [title] => Title 2 [type] => Limited [message] => 39 ) [4] => Array ( [title] => Title 4 [type] => Offline [message] => 41 ) [5] => Array ( [title] => Title 5 [type] => [message] => ) And I want to get this Array ( [1] => Array ( [title] => Title 2 [type] => [message] => ) [3] => Array ( [title] => Title 2 [type] => Limited [message] => 39 ) )

Detecting modifier keys held down during startup in OS/X (or Windows)?

- by Tom Swirly

I've searched here and not found any question that really covers this. I have a cross-platform Windows-OS/X application in which I'd like to be able to detect whether modifier keys like shift or control are being held down while the application starts up. We'd like to do this to allow the application to start up without reading its preferences file, in case that somehow gets corrupted (we saw in testing a prefs bug, now fixed, that made the window size 0 by 0, for example). We're using the excellent and comprehensive cross-platform C++ library named Juce. Unfortunately, Juce's master tells me that he believes this is impossible on OS/X at least since you only get keyboard events and there is no way to read the state of the keys unless something changes. Is this true? Or is there some way around this? I'm almost sure I've used Mac programs that used this mechanism to bypass their preferences. Or... stepping up one level... is there another solution to providing the functionality of "run the program but don't read the prefs file" other than "holding a key down while launching the program"? This is consumer software so we can't expect too much from the user. The final solution will end up being a cross-platform one so hints on the Windows side will also be appreciated. Thanks, and be well! I'll report in with progress on my end.

Is MongoDB a good choice or not for my application?

- by shubham

I have a Reporting application which stores the reports in xml format as recieved from source (XML schema is not defined, it can be any format) and those reports contain some keys and values. Like jobid, setid be keys for 1 type of report and userid, groupId for another type of report etc. The type of keys that can be referred from the document is determined by the namespaces used in the xml doc. These keys are stored on the basis of namespace used in the xml document. For e.g. If a tag in xml fragment uses namespace= "myspace1", then I have keys A and B for myspace1 stored in another table. It will fetch those keys from that table for this namespace, look for their values in xml doc and store it in another table along with the pointer to this xml document (Id of a record storing complete xml document in a cell). Use cases: When the user comes and queries for that key and value, I return the document or a set of documents that are having those key/value pairs. When the user comes and queries for a certain key and provide a name for xslt (pre stored), I fetch the set of documents fulfilling that criteria and convert that xml to html with the specified xslt. When the user comes and asks for a particular fragment of a doc then it can fetch a subset from a particular document also. When the user comes and queries for top x values of a certain key, I return the set of documents that are having top 10 values of that key. I am using DB2 database for its support of xml along with relational capabilities. That makes easier for me to run xpath expressions and fetch values of keys and also aggregate a set of documents fullfilling a criteria, all on the database side. Problems: DB2 stores XML doc of upto 2GB in size. Retrieval is very slow. If some thing involves many documents, then it takes significant time for things to show up in browser, and the user has to wait. Can MongoDb help in this case, as it is document oriented? can I do xml related xpath queries and document transformations on db side? Or is it ok to use both in such a case?

How to make Shared Keys .ssh/authorized_keys and sudo work together?

- by farinspace

I've setup the .ssh/authorized_keys and am able to login with the new "user" using the pub/private key ... I have also added "user" to the sudoers list ... the problem I have now is when I try to execute a sudo command, something simple like: $ sudo cd /root it will prompt me for my password, which I enter, but it doesn't work (I am using the private key password I set) Also, ive disabled the users password using $ passwd -l user What am I missing? Somewhere my initial remarks are being misunderstood ... I am trying to harden my system ... the ultimate goal is to use pub/private keys to do logins versus simple password authentication. I've figured out how to set all that up via the authorized_keys file. Additionally I will ultimately prevent server logins through the root account. But before I do that I need sudo to work for a second user (the user which I will be login into the system with all the time). For this second user I want to prevent regular password logins and force only pub/private key logins, if I don't lock the user via" passwd -l user ... then if i dont use a key, i can still get into the server with a regular password. But more importantly I need to get sudo to work with a pub/private key setup with a user whos had his/her password disabled. Edit: Ok I think I've got it (the solution): 1) I've adjusted /etc/ssh/sshd_config and set PasswordAuthentication no This will prevent ssh password logins (be sure to have a working public/private key setup prior to doing this 2) I've adjusted the sudoers list visudo and added root ALL=(ALL) ALL dimas ALL=(ALL) NOPASSWD: ALL 3) root is the only user account that will have a password, I am testing with two user accounts "dimas" and "sherry" which do not have a password set (passwords are blank, passwd -d user) The above essentially prevents everyone from logging into the system with passwords (a public/private key must be setup). Additionally users in the sudoers list have admin abilities. They can also su to different accounts. So basically "dimas" can sudo su sherry, however "dimas can NOT do su sherry. Similarly any user NOT in the sudoers list can NOT do su user or sudo su user. NOTE The above works but is considered poor security. Any script that is able to access code as the "dimas" or "sherry" users will be able to execute sudo to gain root access. A bug in ssh that allows remote users to log in despite the settings, a remote code execution in something like firefox, or any other flaw that allows unwanted code to run as the user will now be able to run as root. Sudo should always require a password or you may as well log in as root instead of some other user.

I am a newbie to Unix so I "sudo" perhaps unnecessarily here, but I got confirmation in the terminal that it had installed but also some errors: alex@ubuntu:~/NodeHelloWorld$ sudo gem install foreman Invalid gemspec in [/var/lib/gems/1.8/specifications/foreman-0.26.1.gemspec]: invalid date format in specification: "2011-11-10 00:00:00.000000000Z" Invalid gemspec in [/var/lib/gems/1.8/specifications/term-ansicolor-1.0.7.gemspec]: invalid date format in specification: "2011-10-13 00:00:00.000000000Z" Invalid gemspec in [/var/lib/gems/1.8/specifications/foreman-0.26.1.gemspec]: invalid date format in specification: "2011-11-10 00:00:00.000000000Z" Invalid gemspec in [/var/lib/gems/1.8/specifications/term-ansicolor-1.0.7.gemspec]: invalid date format in specification: "2011-10-13 00:00:00.000000000Z" Successfully installed term-ansicolor-1.0.7 Successfully installed foreman-0.26.1 Then when I try to start foreman I get similar: alex@ubuntu:~/NodeHelloWorld$ foreman start Invalid gemspec in [/var/lib/gems/1.8/specifications/foreman-0.26.1.gemspec]: invalid date format in specification: "2011-11-10 00:00:00.000000000Z" Invalid gemspec in [/var/lib/gems/1.8/specifications/term-ansicolor-1.0.7.gemspec]: invalid date format in specification: "2011-10-13 00:00:00.000000000Z" /usr/lib/ruby/vendor_ruby/1.8/rubygems.rb:926:in `report_activate_error': Could not find RubyGem foreman (>= 0) (Gem::LoadError) from /usr/lib/ruby/vendor_ruby/1.8/rubygems.rb:244:in `activate_dep' from /usr/lib/ruby/vendor_ruby/1.8/rubygems.rb:236:in `activate' from /usr/lib/ruby/vendor_ruby/1.8/rubygems.rb:1307:in `gem' from /usr/local/bin/foreman:18 Can anyone help me? I am a newbie to Unix after finally dumping windows as I found I could not get foreman-windows to work for me either I have found this post from someone with apparently the same issue. Does this mean my version of ruby could be wrong? I am running 1.9.1, though again new to ruby as well; alex@ubuntu:~/NodeHelloWorld$ ruby1.9.1 -v ruby 1.9.2p290 (2011-07-09 revision 32553) [i686-linux] Thanks

Is there an high quality natural text reader for the mac?

- by Another Registered User

I'm reading about 150 pages of text on screen, every day. I will have to read about 15.000 in the next upcoming months. No joke. Well, the problem is this: I suffer from a sort of attention deficit hyperactivity disorder which forces me to read every sentence up to 10 times until I really get it. Mac OS X Snow Leopard has a built-in text reader with the name "Alex". Although it is already pretty good quality, I know there are far better natural sounding voices out there. I have heard already voices that are absolutely amazing compared to Alex. They're so good, that you can't tell anymore the difference between a real person or a computer. Alex still has this "metal factor" in its voice, which makes my ears hurt after 8 hours of listening. The next problem with Alex is, that he never makes a break after a sentence. Also, it's not possible to think about a sentence and then continue reading. It's also not possible to have him repeat a sentence, without tedious text selection and shortcut usage. Actually, the best tool I can imagine would have the option to read a sentence and move on to the next one after pressing a special key, OR repeating the previously one after pressing a special key. That would help so much! And if that's even with one of those bell lab / AT&T / whatever super-natural voices, even better! But it would be already a great relief if there was just a better tool to control Alex. To let him make breaks after sentences or let him speak big chunks of text sentence-by-sentence with fine-grained control over repetition and moving on. Is there anything?

Choosing an open source license such that maximum value is added to a startup

- by echo-flow

There are many companies that produce open source software products, and many business models that these companies can use. I'm particularly interested in companies like 280 North, the company behind Objective-J and Cappucino frameworks. My understanding of this organization's business model is that they: worked to develop a tool which added significant value to developers, released the tool under an open source license, built a community around the tool (which was helped by the project's open source licensing), created interesting demos illustrating the project's value All of these things added value to the project, and the company that owned it. Finally, 280 North was sold to Motorola. My question has to do with the role of software licensing in this particular business model. 280 North licensed their software projects under the LGPL, which gave them some proprietary control over how the project could be used. I believe that the LGPL is what's known as a "weak copyleft" license, meaning that the project can be linked to, without the linking code also being licensed under the LGPL; but software derived directly from the project would need to be licensed under the LGPL. For web-oriented libraries in particular, weak copyleft, or non-copyleft licensing seems to be quite common; I can't think of a single example of a popular or well-known web-oriented library that is licensed under the GPL (or AGPL). The question then, is, how much value would a weak copyleft license like the LGPL add to a software venture like 280 North, versus a non-copyleft license, such as the BSD license or the Apache Software License? I'd really appreciate any insight anyone can offer into this, but I'd be most interested in answers that can cite other companies as case studies or examples.
