  • Implementing new required feature after software release

    - by TiagoBrenck
    Fake Scenario There is a software that was released 1 year ago. The software is to map and register all kind of animals on our planet. When the software was released, the client only needed to know the scientific name of the animal, a flag if it is in risk of extinction and a scale of dangerous(that is a fake software and specification, I don't want to discuss this here). There are already 100.000 animals records saved on DB. New Feature One year later, the client wants a new feature. It is really important to him to know the animals classes, and this is a required field. So he asks me to put a field to input the animal class, and this field is required. Or maybe where this animal was discovered. Problem I have already 100.000 recorded animals without a class or where it was discovered, but I need to insert a new column to storage this information and this column can't be null. I don't have a default value for this situation (there isn't a default animal class or where it was discovered). I don't want to keep the requirement rule only on my software, my DB must have this requirement too(I like to keep business rules on DB too). What are the alternatives to solve this situation? I am on a situation that this new feature cannot be previewed or reviewed for the existing records. The time already passed and I can't go back on time to get it

  • Application to organize / manage installed networks

    - by vicmp3
    I was wondering if there is a Application where you can organize networks. I mean if you have installed some networks you have to note every pc's name, his ip-address and so on. Is there a Application where you can manage it? I saw the monitoring tools but that is not exactly what I'm looking for. Maybe I didnt explain me well, after all my englis his not so good :) For example if I install many different networks I write in a book how I configured them. I write pc-name ip-address ip-gateway ip-broadcast and so on for each network. It will be great if I can do it in a program to organize it well, and for example it gives me a node view of the network.

  • Why is it good to have website content files on a separate drive other than system (OS) drive?

    - by Jeffrey
    I am wondering what benefits will give me to move all website content files from the default inetpub directory (C:) to something like D:\wwwroot. By default IIS creates separate application pool for each website and I am using the built-in user and group (IURS) as the authentication method. I’ve made sure each site directory has the appropriate permission settings so I am not sure what benefits I will gain. Some of the environment settings are as below: VMWare Windows 2008 R2 64 IIS 7.5 C:\inetpub\site1 C:\inetpub\site2 Also as this article (moving the iis7 inetpub directory to a different drive) points out, not sure if it's worth the trouble to migrate files to a different drive: PLEASE BE AWARE OF THE FOLLOWING: WINDOWS SERVICING EVENTS (I.E. HOTFIXES AND SERVICE PACKS) WOULD STILL REPLACE FILES IN THE ORIGINAL DIRECTORIES. THE LIKELIHOOD THAT FILES IN THE INETPUB DIRECTORIES HAVE TO BE REPLACED BY SERVICING IS LOW BUT FOR THIS REASON DELETING THE ORIGINAL DIRECTORIES IS NOT POSSIBLE.

  • Is it possible to get xRandR to see two separate outputs with the nvidia driver?

    - by rumtscho
    I have two monitors, which I have set up with nvidia-settings in Twinview. The result: When I want to do something in xRandR, it does not function. It doesn't report one output per video card head, but a single output mapped to the combined area of both monitors: rumtscho@bradbury:~$ xrandr xrandr: Failed to get size of gamma for output default Screen 0: minimum 3840 x 1440, current 3840 x 1440, maximum 3840 x 1440 default connected 3840x1440+0+0 0mm x 0mm 3840x1440 50.0* Now I promised somebody to help test a driver. The developer is using an open source driver for Intel video cards, and his driver assumes that there is more than one xRandR output, each mapped to a monitor. So I tried rewriting my xorg.conf to somehow get two outputs to show up, but failed. Googling showed that people faced with the xRandR-nvidia problem either stopped using xRandR and achieved what they needed with nvidia-settings, or changed their driver to nouveau. The first is not going to help in my situation, and I am not willing to give up the proprietary driver, because Compiz won't work without it. So does anybody know a way to get nvidia to actually pass on information on outputs to xRandR?

  • Why don't languages use explicit fall-through on switch statements?

    - by zzzzBov
    I was reading Why do we have to use break in switch?, and it led me to wonder why implicit fall-through is allowed in some languages (such as PHP and JavaScript), while there is no support (AFAIK) for explicit fall-through. It's not like a new keyword would need to be created, as continue would be perfectly appropriate, and would solve any issues of ambiguity for whether the author meant for a case to fall through. The currently supported form is: switch (s) { case 1: ... break; case 2: ... //ambiguous, was break forgotten? case 3: ... break; default: ... break; } Whereas it would make sense for it to be written as: switch (s) { case 1: ... break; case 2: ... continue; //unambiguous, the author was explicit case 3: ... break; default: ... break; } For purposes of this question lets ignore the issue of whether or not fall-throughs are a good coding style. Are there any languages that exist that allow fall-through and have made it explicit? Are there any historical reasons that switch allows for implicit fall-through instead of explicit?

  • When Ubuntu Server restarts eth0 Doesn't come back up

    - by JoelGsus
    Every time I restart my Ubuntu Server 11.10 I can't ssh into it because ETH0 doesn't come up automatically. I never had this problem before upgrading to 11.10. I have to login to the server and start the ETH0 manually. I would appreciate it any help. Thanks. Here is my /etc/networks/interfaces file: #The loopback network interface auto lo eth0 iface lo inet loopback # The primary network interface iface eth0 inet static address 192.168.1.102 netmask 255.255.255.0 broadcast 192.168.1.255 network 192.168.1.0 gateway 192.168.1.1

  • How do I open multiple windows when Outlook 2010 starts?

    - by Eric
    OS: Windows 7 64-bit App: Outlook 2010 32-bit Server: Exchange 2010 I'd like to modify Outlook's default startup behavior so that it shows both my Inbox and Calendar when I click my shortcut. I use both of them all day, and know how to just right-click the calendar and select "Open in New Window." I run my inbox on one screen and my calendar on another. I also configured my calendar to be the folder that opens by default when I start Outlook so I don't miss early appointments, but if I could somehow have BOTH open in two separate windows, that would be awesome. Is there a command-line interface or something that can accomplish this? Thanks in advance.

  • Changing Admin Site URL (actually port) - how?

    - by TomTom
    I have a new install of the band new SharePoint 2010. I use host header identified site collections for everything. By default the admin site is on a random port. I would like to move the admin site to port 80, for the server name. As all sites have coded names (for example "intranet", "projects") this would allow administration via the server name - which is easier as external access does not have to remember the port number. How do I do this? I already changed the default URL, but the site (application) is still wrongly mapped. I dont find anything to change the IIS settings in the admin site. I possibly just miss it - so can anyone point me in the right direction?

  • FeedValidator & Feedburner get 404 when accessing wordpress RSS feeds when permalinks are enabled.

    - by Wazbaur
    I'm helping a friend set up a self-hosted Wordpress blog + feedburner and I'm seeing a problem with the feeds that I'm finding somewhat mysterious. Using the default permalink structure (e.g., ?p=123) everything works as expected; I can follow the feed in Google reader, navigate to it manually, and set it up in feedburner. However, once I switch away from the default permalink structure, feedburner and feedvalidator both report that accessing the feed is returning HTTP-404 and Google reader no longer shows new posts (I'm assuming for the same reason), but I can navigate to the feed using a browser. When I do that it appears as though nothing is wrong; there is a feed there and it contains all the posts I expect it to have. I've re-started the feedburner & reader set-up from the beginning after changing the link structure, so I don't think they're doing anything silly like looking at the feed at its old address. I've seen people with similar problems in various other places but there doesn't seem to be a good answer anywhere.

  • Gigaom Article on Oracle, Freescale, and the push for Java on Internet of Things (IoT)

    - by hinkmond
    Here's an interesting article that came out during JavaOne which talks about the Oracle and Freescale partnership, where we are putting Java technology onto the Freescale i.MX6 based "one box" gateway. See: Oracle and Prosyst team up Here's a quote: When it comes to connected devices, there’s still plenty of debate over the right operating system, the correct protocols for sending data and even the basics of where processing will take place — on premise or in the cloud. This might seem esoteric, but if you’re waiting for your phone to unlock your front door, that round trip to the cloud or a fat OS isn’t going to win accolades if you’re waiting in the rain. With all of this in mind, Oracle and Freescale have teamed up to offer an appliance and a Java-based software stack for the internet of things. The first version of the "one box" will work in the connected smart home, but soon after that, Oracle and Freescale will develop later boxes for other industries ranging from healthcare, smart grid to manufacturing.

  • WebSVN accept untrusted HTTPS certificate

    - by Laurent
    I am using websvn with a remote repository. This repository uses https protocol. After having configured websvn I get on the websvn webpage: svn --non-interactive --config-dir /tmp list --xml --username '***' --password '***' 'https://scm.gforge.....' OPTIONS of 'https://scm.gforge.....': Server certificate verification failed: issuer is not trusted I don't know how to indicate to websvn to execute svn command in order to accept and to store the certificate. Does someone knows how to do it? UPDATE: It works! In order to have something which is well organized I have updated the WebSVN config file to relocate the subversion config directory to /etc/subversion which is the default path for debian: $config->setSvnConfigDir('/etc/subversion'); In /etc/subversion/servers I have created a group and associated the certificate to trust: [groups] my_repo = my.repo.url.to.trust [global] ssl-trust-default-ca = true store-plaintext-passwords = no [my_repo] ssl-authority-files = /etc/apache2/ssl/my.repo.url.to.trust.crt

  • mod_rewrite and SEO friendliness

    - by John Doe
    My website has an atypical structure and I'm not sure if this could create problems in the long run, specially for SEO positioning purposes. I have a unique, large PHP script, and I use the Apache module mod_rewrite in the .htaccess file to create friendly URLs, for example: RewriteRule ^$ /index.php?section=Main RewriteRule ^createArticle$ /index.php?section=Main&view=CreateArticle RewriteRule ^configuration$ /index.php?section=Configuration RewriteRule ^article/([0-9]{1,10})$ /index.php?section=Article&view=Default&id=$1 RewriteRule ^deleteArticle/([0-9]{1,10})$ /index.php?section=Article&view=Delete&id=$1 RewriteRule ^reportArticle/([0-9]{1,10})$ /index.php?section=Article&view=Report&id=$1 RewriteRule ^logIn$ /index.php?section=Authentication ... So, www.example.com/index.php?section=Article&view=Default&id=105 would become www.example.com/article/105. The only real physical file is index.php, in which the parameters of the URL queried is processed and the corresponding result is outputted. My question is, do the crawling robots (e.g. Googlebot) recognize these links? Do they index the resulting HTML outputted by index.php with the specified parameters as if it was a actual HTML file? Also, would this become a problem when creating a Sitemap?

  • receiving "command not found" error messages after fresh reinstall of Lubuntu 14.04

    - by user236378
    Lubuntu 14.04 was working really great. . .until I messed up and had to do a complete fresh reinstall. Now I receive error messages when I input commands into the Terminal, even after immediately completing the fresh install. For example I type: sudo leafpad ?/etc/default/ or sudo leafpad ?/etc/default/grub I get: sudo: leafpad: command not found I type: sudo update-initramfs ?-u or sudo update-grub I get: sudo: update-initramfs: command not found or sudo: update-grub: command not found If I use the command mkdir I get: mkdir: command not found I also get this same exact error message, command not found, with sudo apt-get and wget In other words I can't do anything that I was able to do when inputting commands into the terminal. So I cannot add any repositories or update anything at all. I am not really sure what is causing the problem(s). It appeared to me that Lubuntu installed and booted up OK. However just as soon as I enter anything into the Terminal I immediately get the above error messages. I have tried to do the reinstall three times, same error messages. If anyone can suggest any fixes I would really appreciate it very much. Thank you!

  • 1080p Screen resolution problem after 10.04 to 12.04 update

    - by Ale
    I have a Samsung LCD 40" with a NVidia GeForce 6150SE nForce 430 Card. I recently upgraded from 10.04 to 12.04 and the best resolution I can get is 1360x768. I've tried the propietary drivers available on the repository kmod:nvidia_current kmod:nvidia_173_updates kmod:nvidia_current_updates kmod:nvidia_96 kmod:nvidia_96_updates kmod:nvidia_173 I've also downloaded latest from NVidia's Web, version: 295.40. But still no luck. With Nouveau driver, I can only get 1024x768. I know there is no problem with my hardware (video card, cable and monitor), I was using it perfectly on 10.04. Can anybody suggest something else I could try, to get my 1920x1080 resolution back? Thanks in advance.

  • SmS Gateways - How do other sites do it? [closed]

    - by chobo2
    Possible Duplicate: Send and Receive SMS from my Website I would love to have a feature on my site that sends Email reminders and SmS(text messages) to people mobile phones. I been searching around and all I am finding is api's that charge money per SmS message(as low as 1cent per message). However even at 1cent per message that is still too much. The amount of money I am charging per year could be servilely eroded by just the Sms messages along. I could of course charge more money for my service or have an add on for SmS messages but I don't think either would work as most people expect it to be free feature and if they have to pay anything that is because of their carrier charging them not the website. How do other sites do it? I guessing companies like google have their own gateway providers or something like that. But how about smaller sites what do they do? I can't see them paying per sms text message.

  • Prevalence of WMI enabled in real Windows Server networks

    - by TripleAntigen
    Hi I would like to get opinions from systems administrators, on how common it is that WMI functionality is actually enabled in corporate networks. I am writing an enterprise network application that could benefit from the features of WMI, but I noted after creating a virtual network based on Server 2008 R2, that WMI seems to be disabled by default. Do systems admins in practical corporate networks enable WMI? Or is it usually disabled for security purposes? What is it used for if it is enabled? Thanks for any advice! MORE INFO: I should have said, I really need to be able to query the workstations but I understand that by default the WMI ports on Win7 and XP firewalls (at least) are disallowed, so do you use some sort of group policy or other method to leave a hole open for WMI on the workstations? Or is just the servers that are of interest? Thanks for the responses!!

  • Inaccurate bandwidth limiting in altq queues

    - by overkordbaever
    I'm setting up an environment where I have one Linux server, one OpenBSD router and one Linux client and I want to be able to limit how much bandwidth the client should be able to use. I've been performing these tests with "netcat" and "time" (using time to measure the time of the transfer with netcat), and what happens when trying these tests (using the TCP protocol, the queues will for some reason not work with UDP) is that the queues aren't exact at all. For example: when setting a bandwidth limit of 10mbit, the client cannot use more than five mbits, when setting a limit of 100mbit, the client cannot use more than around 50mbit. The config looks like (using a 100mbit limit in the example): #queue rules altq on { $int_if, $ext_if } cbq bandwidth 100Mb queue { def, low } queue def bandwidth 0Mb cbq(default) queue low bandwidth 100Mb cbq(default) #Passrules test pass out quick from $int_if to $ext_if queue low pass in quick from $ext_if to $int_if queue low pass out quick from $ext_if to $int_if queue low pass in quick from $int_if to $ext_if queue low

  • Static IP breaks Network connection

    - by Pasquale Tedesco
    I am somewhat new to Linux. I am setting up a Web server and installed Ubuntu server 14.04 on an vSphere ESXi 5.5 host. I am connecting perfectly fine to the internet when using DHCP but when I apply my Static settings I loose the ability to connect to websites. Whats weird is I can Ping google.com but if I try wget gooogl.com it hangs at connecting to google.com (google.com):173.194.43.32:80 and I get "failed: connection refused" But if I am set to DHCP the connection resolves perfectly.

  • I can't get grub menu to show up during boot

    - by wim
    After trying (and failing) to install better ATI drivers in 11.10, I've somehow lost my grub menu at boot time. The screen does change to the familiar purple colour, but instead of a list of boot options it's just blank solid colour, and then disappears quickly and boots into the default entry normally. How can I get the bootloader back? I've tried sudo update-grub and also various different combinations of resolutions and colour depths in startupmanager application with no success (640x480, 1024x768, 1600x1200, 16 bits, 8 bits, 10 second delay, 7 second delay, 2 second delay...) edit: I have already tried holding down Shift during bootup and it does not seem to change the behaviour. I get the message "GRUB Loading" in the terminal, but then the place where the grub menu normally appears I get a solid blank magenta screen for a while. Here are the contents of /etc/default/grub # If you change this file, run 'update-grub' afterwards to update # /boot/grub/grub.cfg. # For full documentation of the options in this file, see: # info -f grub -n 'Simple configuration' GRUB_DEFAULT=0 GRUB_HIDDEN_TIMEOUT=0 GRUB_HIDDEN_TIMEOUT_QUIET=true GRUB_TIMEOUT=10 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" GRUB_CMDLINE_LINUX=" vga=798 splash" # Uncomment to enable BadRAM filtering, modify to suit your needs # This works with Linux (no patch required) and with any kernel that obtains # the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...) #GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef" # Uncomment to disable graphical terminal (grub-pc only) #GRUB_TERMINAL=console # The resolution used on graphical terminal # note that you can use only modes which your graphic card supports via VBE # you can see them in real GRUB with the command `vbeinfo' #GRUB_GFXMODE=640x480 # Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux #GRUB_DISABLE_LINUX_UUID=true # Uncomment to disable generation of recovery mode menu entries #GRUB_DISABLE_RECOVERY="true" # Uncomment to get a beep at grub start #GRUB_INIT_TUNE="480 440 1"

  • Having set up a DCHP server, what do I need to do for the rest of my network?

    - by fredley
    I've got a Raspberry Pi arriving any day now, and I intend to use it (amongst other things) as a DHCP server. Currently we have a few devices on our network to which we would like to assign static IPs, and a router, which is currently the DHCP server (the router can assign static IPs, but is buggy as hell, I've never got the config to stick for more than a few hours). Having connected the Pi to the network and configured dhcpl-3-server, what do I need to do on the rest of my network so that it works properly (clients get their IPs from the Pi, and use the Router as the default gateway)?
