• XMLRPC with long integer entry in hashMap from java server is not obtained in ruby client

  - by Mahesh M

  I am using XMLRPC to get data from a Java server. I use HashMap as return value for a particular remote call. The server puts a long int into the HashMap (which is returned) along with other data. At the client end, which is ruby, I get all other data but for the long int. How can I get this data at the client?

• What is on your desk?

  - by Jack

  I have read that what you keep on your desk is very influential in how you work and your level of productivity. I am trying to optimise the way that I work (I am a terrible procrastinator), and am curious what other programmers' desks look like. What do you have on your desk? Is there anything you deliberately avoid? There is no need to mention if you have things like computer, screen, mouse, keyboard, or speakers.

• CentOS - mdadm raid1 drive won't mount to default location

  - by danny

  I'm running CentOS 5.5, the system, boot, swap, etc. is all on /dev/sda and I have two identical single-partition drives /dev/sdb1 /dev/sdc1 that are configured in RAID1 (using mdadm). It was working fine (configured to mount to /mnt/data in the fstab file) and I recently let yum install a couple of automatic updates without paying attention to what they were, and now it doesn't work. Raid is working fine (dmesg shows it gets loaded correctly). mdstat shows: # cat /proc/mdstat Personalities : [raid1] md0 : active raid1 sdc1[1] sdb1[0] XXXX blocks [2/2] [UU] unused devices: <none> Additionally, I can mount it anywhere other than its default directory (i.e. the following works, and I can read data off the drives). # mount /dev/md0 /mnt/data2 EXT3-fs warning: mounting fs with errors, running e2fsck is recommended But when I run the following I get: # mount -a mount: /dev/sdb1 already mounted or /mnt/data busy It says nothing is mounted when I try to umount /dev/sdb1 or umount /mnt/data, so I assume it's the second of those errors. However, lsof | grep mnt shows nothing. The weird thing is that I can save files in /mnt/data. So something is obviously mounted there, but when I try to umount it I get the error that nothing is mounted. /etc/mtab doesn't mention any of the partitions or files I am trying to work with, and fstab just has that one line I mentioned above that is supposed to mount my raid partition. Again, it was all working fine until I On Google I've found a few things about dmraid interfering with mdadm after an update, but I yum remove'd dmraid and rebooted and it didn't help. I'm really confused and need to get this working to get on with my work!

• Is there a difference between only <NSXMLParserDelegate>, only setDelegate method, or the use of bot

  - by gotye

  Hey, I noticed that when I do this : [myParser setDelegate:self]; it works :D (even if I didn't add the code in the header file ... you know, the <delegateStuff, delegateOtherStuff> in the interface declaration) When are you supposed to modify the header file to make your delegate work ? Is the setDelegate method enough to make it work ? Cheers for any help ;) Gauthier

• Windows server 2008, Dns. I'm confused

  - by Dejan.S

  Hi. I recently setup a window server 2008 server at work. Keep in mind I have never worked with it before:). Background story is I try to host a couple of sites on the server through iis7, I got domains (currently hosted at other hosters for the moment). I want to point the domain NS to my server on all of them. I have read how to setup a DNS on the server, so far so good. now my dns is companyname.com in the server manager I got DNS / companyname.com in there I got ns.comanyname.com, in there I got Host(A) with the server ip now this is where I get confused about how things work with DNS, NS & Host(A). I dont know how to assign(so to speak) the Host(A) to one of my webapps hosted on the iis7, because that is the pointer right?. To leave an example to work with lets say, Hosted.com is hosted on my iis7, on port 81. You don't understand how great full I would be if somebody could explain this confusion. EDIT: Do I need to create a DNS for every site hosted on my server? Or just make a A Host/Record? Thanks guys

• PHPUnit won't run tests by directory

  - by Frank Schwieterman

  I'm new to PHP, trying to get multiple tests to run at once. I was hoping to just run all tests in a directory, which seemed to work awhile (instead of using a phpunit.xml). I am able to run a test individually like so: phpunit FirstUnitTest sites\all\modules\experiment\unit-tests\FirstUnitTest.lua But when I try to run the same test by directory, its not found. I try using: phpunit sites\all\modules\experiment\unit-tests Does anyone know why this may not work?

• How do I convert from unicode to single byte in C#?

  How do I convert from unicode to single byte in C#? This does not work: int level =1; string argument; // and then argument is assigned if (argument[2] == Convert.ToChar(level)) { // does not work } And this: char test1 = argument[2]; char test2 = Convert.ToChar(level); produces funky results. test1 can be: 49 '1' while test2 will be 1 ''

• How to reset the postgres super user password on mac os x

  - by Andrew Barinov

  I installed postgres on my mac running 10.6.8 and I would like to reset the password for the postgres user (I believe this is the super user password) and then restart it. All the directions I found do not work because I think my user name is not recognized by pg as having authority to change the password. (I am on the admin account of my mac) Here is what I tried: Larson-2:~ larson$ psql -U postgres Password for user postgres: psql (9.0.4, server 9.1.2) WARNING: psql version 9.0, server version 9.1. Some psql features might not work. Type "help" for help. postgres=# ALTER USER postgres with password 'mypassword' postgres-# \q and for restart I did: Larson-2:~ larson$ su postgres -c 'pg_ctl -D /opt/local/var/db/postgresql84/defaultdb/ restart > Which didn't work, as the password remained the same as it was before. Can someone provide directions for doing this and for making sure it's recognized by PG? Update I went ahead and edited the pg_hba.conf file located in /Library/PostgreSQL/9.1/data and set the settings as follows: # TYPE DATABASE USER ADDRESS METHOD # "local" is for Unix domain socket connections only local all all trust # IPv4 local connections: host all all 127.0.0.1/32 trust # IPv6 local connections: host all all ::1/128 trust However, like before, the password stayed the same after I changed it. I am not sure what further steps I can take from here.

• Highlighting company name in Eclipse stack traces

  - by Robin Green

  Is there a way to make Eclipse highlight com.company (where for company substitute the name of the company you work for) in stack traces? It would make it fractionally easier and faster to home in on which parts of the stack trace were ours, and which were third-party code. I tried the logview plugin here, and while it does work, it makes the location information in the stack traces unclickable, which means I would waste more time than I would save.

• Oracle java 6 on ubuntu

  - by Shanee

  The java library I need (jpcap) only works on java 6, it won't work with java 7 (and I have tried :( ), is it still possible to install java 6 on ubuntu? Only according to https://help.ubuntu.com/community/Java#Choosing_the_default_Java_to_use, 'Oracle (Sun) Java 6 is no longer available to be distributed by Ubuntu, because of license issues' I've tried to use the instructions on the same site but they don't seem to work... "./jre-6u34-linux-i586.bin" doesn't seem to do anything! Thanks!

• What is the web.debug.config and web.release.config file for?

  - by chobo

  Hi, I just upgraded to VS 2010 and MVC 2.0 and I noticed the web.config has two additional files attached to it? Are thee files used to specify debug and release specific settings, so you don't clutter up the main web.config? Does it even make sense to place a connection string in the root web.config file if I have have a local and remote one in the debug and release web.configs respectively. Thanks!

• Windows Virtual Machines will not run

  - by jlego

  I'm trying to setup a few virtual machines to use for testing websites in the various old versions of IE. I had Microsoft Virtual PC working on an older machine using XP mode and 2 other VHD's from Microsoft that allowed me to test in IE6-IE8. I've recently gotten a new work machine and am trying to set up the VMs again for testing, however nothing seems to be working. Both the old and the new system run Windows 7 64-bit Ultimate with AMD processors. I downloaded Virtual PC & XP mode from here http://www.microsoft.com/windows/virtual-pc/download.aspx and go through the installation process. XP mode is installed, but when I try to run it it goes through the initial setup process only to fail when it is almost complete with the error "Cannot Complete Setup". (After googling I see that this might be a conflict with my processor) I download other VHD's from here http://www.microsoft.com/windows/virtual-pc/download.aspx in order to get the other versions of IE and try to set those up in Virtual PC as well. I click on them to start the machine and both Windows 7 with IE8 and Windows Vista with IE7 just hang at a black screen. I try to use Virtual Box instead, and I get Windows XP with IE6 running, but I have no internet connection in the VM. I try all different settings and try to google the correct settings but nothing seems to work. When I load the VM, XP shows that its found new hardware but it needs the drivers. One of these pieces of hardware is the network adapter, but I can't connect to the internet to download the driver in the guest OS. VirtualBox tells me I need to install extensions in order for things to function properly. I go through the installation process in the guest OS and restart the VM, however now XP is asking for validation and I can't access the VM. I try installing the other 2 OS (Vista & 7) but I get a BSOD right after the startup screen appears and the VM restarts itself. I'm getting so frustrated trying to make this work, I would really appreciate any assistance on getting the VMs up and running or any alternatives for testing websites in Internet Explorer.

• RegExp: want to find all links that do not end in ".html"

  - by grovel

  Hi, I'm a relative novice to regular expressions (although I've used them many times successfully). I want to find all links in a document that do not end in ".html" The regular expression I came up with is: href=\"([^"]*)(?<!html)\" In Notepad++, my editor, href=\"([^"]*)\" finds all the links (both those that end in "html" and those that do not). Why doesn't negative lookbehind work? I've also tried lookahead: href=\"[^"]*(?!html\") but that didn't work either. Can anybody help? Cheers, grovel

• who do you admire in a scientific/technical field [closed]

  - by Tshepang

  This off-topic item refers to people with major achievements in fields such as engineering, science, and mathematics. Here's my picks: Eric Drexler for his work on molecular nanotech. His book, Engines of Creations, is mind-blowing. Robert Freitas for his work on molecular nanotech. The breadth of his multi-volume book, Nanomedicine, is impressive. Richard Stallman for promoting Free Software.

  When updating from subversion repository using tortoise svn client I get error looking like that: Could not read chunk size: An existing connection was forcibly closed by the remote host.

• Adobe AIR: problem with OpenID / rpxnow logins

  - by michael

  Does Adobe Air work with OpenID/rpxnow? I'm having a developer build me an AIR app to work with my website so I can have access to desktop photos. However, my site uses OpenID logins via the rpxnow.com implementation. Works fine in the web version, but my developer has told me that he cannot do rpxnow/openid logins from the AIR app because it doesn't allow pop-ups and/or redirects. Has anyone found a workaround? m.

• What is the big deal with IQueryable?

  - by jjr2527

  I've seen a lot of people talking about IQueryable and I haven't quite picked up on what all the buzz is about. I always work with generic List's and find they are very rich in the way you can "query" them and work with them, even run LINQ queries against them. So I'm wondering if there is a good reason to start considering a different default collection in my projects.

• OpenVPN, install a TAP adapter

  - by GolezTrol

  When I try to connect to my work VPN using OpenVPN, the connection fails with the message: All TAP-Win32 adapters on this system are currently in use. Many sources suggest to look in Control Panel\Network and Internet\Network Connections an enable the TAP adapter, but when I look there, there is none. Now I've run addtap.bat which is provided with OpenVPN, but I still don't get to see any TAP adapter, and logging in in VPN still fails. The output of addtap.bat is C:\Windows\system32>"C:\Program Files (x86)\OpenVPN\bin\tapinstall.exe" install "C:\Program Files (x86)\OpenVPN\driver\OemWin2k.inf" tap0801 Device node created. Install is complete when drivers are updated... Updating drivers for tap0801 from C:\Program Files (x86)\OpenVPN\driver\OemWin2k .inf. Drivers updated successfully. I've Run As Administrator both the setup of OpenVPN and addtap.bat. I've run deltapall.bat to remove any (maybe hidden) adapters. It said it removed three of them, after which I ran addtap.bat again to try to create another one. I also run OpenVPN itself as administrator. What's wrong? Running Windows 7 Home Premium on a HP Pavilion dv7 4050ed. It has worked before, but I recently had to reinstall my laptop, for which I used the restore disks I created when I just got it. Everything else seems to work fine. == UPDATE == The TAP adapter is found in Device Manager, but apparently it is disabled because it is incompatible with Windows 7 64bit. I've deïnstalled OpenVPNGui, downloaded a version that should be 64bit compatible, and installed that. Still no cigar. Then I found a tip to install OpenVPN (version 9) after installing OpenVPNGui, because that installs OpenVPN version 8. Now I got a v9 TAP driver in Device Manager, but it still doesn't work and shows up in device manager with an exclamation mark, and not at all in my network devices.
