  • Where does Rails get it's datetime for creating records?

    - by gwapEs9
    I have a rails app with a data model called 'jobs' and i'm faced with a critical design choice crossroads. I don't know enough about Rails and it's inner workings to be able to say for sure what I should do despite a complete read of the rails and ruby docs. I want to be able to accurately display the age of a job record in days. So when a customer logs in, they can see that the job they submitted is 'x' days old. Where does a rails app on Heroku get it's time stamps? From Heroku? or the customers system clock? If a customer has a out of date system clock and submits a job, it could really mess up the sorting of their job list, not to mention me the overseer of job records. Any advice out there? EDIT: Just to be clear, i'm not asking how to list jobs by their date, but to which clock does a rails app on Heroku base it's records.

  • Cannot save all of the property settings for this Web Part.

    - by ybbest
    I would like to display all the items of custom content type of Animals in a SharePoint content query WebPart. After choosing the appropriate values in the web part editor and click on Save I got this error: Cannot save all of the property settings for this Web Part. There is a problem with one or more of the field values below. But when I examine all the values below , it does not flag any error information. I finally manage to locate the error flag after I expand the presentation section. I then delete the text in the Link textbox , now I can save the settings. However , I think the error message should have been more specific so that users can quickly locate the error. The worst part for this is that I did not even change anything in the presentation section, I merely configure the Source in the Query section. Well, I guess I am still new to SharePoint, I just have to get used to these generic error message ):

  • Can't connect to wireless without typing sudo modprobe b43 in terminal

    - by user90889
    I just upgraded to 12.04 on an old ACER Travelmate 5320 using Broadcom 4311. I wasn't able to connect to the internet through the wireless for a few days. It didn't even display wireless networks. I was finally able to make it work by following the instructions found here: http://linuxwireless.org/en/users/Drivers/b43#supported However, each time I log on to the computer I have to go to the terminal and type sudo modprobe b43 to make the wireless work. Is there somehow I can avoid this? I have used Ubuntu for many years but always relied on other people to help me with the technical stuff. The terminal is alien to me so I literally follow online forum instructions without knowing what I'm doing. Also, I tried many many things before I managed to make it work. So I'm worried I may have installed something that now conflicts with whatever the sudo modprobe b43 does. Thank you

    - by Tigz
    I Just recently installed desktop 12.10 on laptop, all was working fine logged in and it stated it wanted to update as it found updates. naturally I let it update and it asked me to reboot to use the new updates did that, now it boots fine i get login prompt. login as per normal then all i get is background with nothing else, if i turn off the wireless i get the disconnection notification pop up but i have nothing else on screen any wrror messages gets displayed as well but their is nothing. their was one program that failed that no longer prompts which gives options of reloading or just closing and continuing either way it just look like it hangs I can ctrl alt del to log out and it does that fine but still wont load no mater how many times i try saw a topic about a ati driver playing up which he typed the following in a ty which i can get to all of them as well. export DISPLAY=:0;gnome-shell --replace the answer i got back was the program gnome-shell is not installed you can install it by typing sudo apt-get install gnome-shell i also tried sudo pkill X which did nothing any help would be appreciated Thanks

  • What's involved in resetting the graphics device?

    - by Donutz
    I'm playing with XNA 4.0, VS2010. I've created a window (not maximized) and drawn some sprites. All is good until I resize the window, after which the sprites stop displaying or only partially display. I'm pretty sure it has something to do with needing to reset the device or something, but can't find any clear instructions or sample code. It's not just a case of needing to increase the preferredbackbuffer size, because even if I shrink the window I get this symptom. I've looked at the source code that I was able to get from Microsoft before they shut down XNA, but it doesn't actually explain anything. Any help or advice? If it makes any difference I'm creating DrawableGameComponents and doing my updates and drawing in their Draw/Update routines.

  • 2-D Lighting Theory

    - by Richard
    I am writing a rogue-like 'zombie' management game. The game map will be similar to Prison Architect. A top-down 50 X 50 grid. I want to implemented a day night cycle and during the night I would like the player to be able to position lights. I would like to be able to lighten and dark to whole map to display the day and night cycle. Then lights would be a circle of light blocked by game entities such as walls, players, trees etc. How would I achieve and what is the standard way of achieving this?

  • Menu bar and launcher missing in new installation of ubuntu 13.04

    - by Assimiz
    I have just installed ubuntu 13.04 on my ThinkPad laptop. I am missing the launcher and upper bar. I only found references to the same problem for upgrades, so I tried everything written here, here and here with no success. However, referring to the second link, I ran ccsm and found my Ubuntu Unity Plugin unchecked. Checking it required to also enable the OpenGL and so I did. But, apparently I am unable to enable the OpenGL. Trying to enable it manually...and the checkbox gets automatically unchecked after few seconds. Please help. Update: I have Intel graphics driver, maybe the problem is specifically with it?. I also tried running ccsm after logging using CTRL+ALT+F1 like given here. I was able to enable OpenGL and the Ubuntu Unity Plugin there, but still, no effect on my display, also after reboot.

  • OKI-B2540 printer doesn't print?

    - by NCLI
    There is a driver for the OKI-B2520, and it is automatically selected when the printer is connected. From looking at various websites, it seems like the B2500, B2520, and B2540 all work perfectly fine with the OKI-B2520 driver, so I let it install that. Everything went smoothly, the printer shows up as available, and I can queue jobs without any problems, and they disappear after a few seconds. However, nothing actually comes out. There is no error message on the printer display, or from Ubuntu. This is the output from the CUPS error log: http://pastebin.com/S6ifZAup So my question is: What is wrong??

  • Microsoft Launches Outlook.com

    Microsoft announced the news in its Outlook blog, calling the new service modern email for the next billion mailboxes. The company is touting a fresh, clean user interface with fewer pixels in the header and no display ads; it should work well on portable devices. Another key point: it uses Exchange ActiveSync to synchronize your mail, calendar and social experience across your smartphone, tablet and desktop computer. Perhaps the biggest advance, though, is that Microsoft is connecting the email service to Facebook, Twitter, LinkedIn, Google; Skype will be part of this list, too, though i...

  • Web programming, standard way to deal with a response that takes time to complete

    - by wobbily_col
    With normal form submission I use the pattern Post / Redirect / Get, when processing the forms. I have a database application built with Django. I want to allow the users to select a number of items from the database, then launch a computationally intensive task based on those items. I expect the task to take between 10 minutes and 2 hours to complete. Is there a standard approach to dealing with requests like this (i.e. that don't return immediately)? Ideally there would be some way to display the progress.

  • Transfer iptables rules to another server (almost) real time

    - by MrShunz
    I'm running 2 cPanel servers with ConfigServer Security & Firewall plugin. One of the functions of the plugin is to block via iptables (temporarily and/or permanently) IPs which fail various authentications (POP3/IMAP, SMTP, FTP, webmail, mod_security and such). Now, i'd like to push those IP blocks to the border router to drop packets as soon as possible (and doing so protecting the other machines on the network). Keep in mind that after N failed logins IP is blocked for 5 minutes, then re-allowed. If multiple bans occours in an hour IP is blocked permanently and should be unlocked "by hand". So I need a near realtime solution. What I'm looking for is a better way than firing some cronjobs both on cPanels and border router to: dump the rules to file transfer the file to border router (via scp/sftp) load the rules from the file in the border router I'm aware that I will need some scripts to parse and modify the rules as cPanels have one ethernet interface and some aliases while border router has two ehternet interfaces and some loopbacks. All machines involved use Linux. EDIT as per @pjmorse comment. The plugin consists of a bunch of perl and config files. The part I'm intrested in is a process which scans logfiles (lfd) and installs iptables rules (and sends an alert email). Fact is, it upgrades quite often (one or two times a week) and itself is 7000 lines of perl so I'm not comfortable on tampering with it.

  • Bridging networks problems

    - by Eric
    In my setup I have 3 computers and 2 (wireless d-link) routers. Computer1 has ethernet and wireless interfaces ethernet : 192.168.0.x (DHCP) wireless : 192.168.10.254 (static) Computer 2 has ethernet with two ips ethernet1 : 192.168.0.90 (static) ethernet2 : 192.168.10.110 (static) Computer 3 is a particular device with a hardcoded ip that I can't change wireless : 192.168.10.41 (static) Router1 manages internet and DHCP for network 192.168.0.0/24 Router2 is more complicated. I don't use DHCP. I use it to bridge between both networks. Its static ip is 192.168.10.1 Computer1 can ping Computer2. Computer1 can ping Computer3. Computer1 can ping Router1. Computer1 cannot ping Router2. Computer2 cannot ping Computer3. Computer2 can ping Router2. Router1 can ping Router1 Router2 can ping Computer2 Router2 cannot ping Computer1 Router2 cannot ping Computer3 This is very weird. Router2 manages the wireless connection, it should be able to ping its own computers right? My question is obviously : How can I make it so Computer2 can access everything else. This is a traditional case of "it was working before christmas and now it doesn't". The ethernet wiring is as follow : [ Computer1 ]----[ Router1 ]---[ Router2 ]---[ Computer3 ] I am using switch (lan) ports on Router1/2.

  • Layering Design Pattern in Java clean code style

    - by zeraDev
    As a Java developer, I am developing trying to use the clean code rules. But in my team we are facing a concrete problem: We have a business layer offering a service called "createObject", this service makes a lot of operation which can result to problem. E.g: parentObjectDontExist, objectAlreadyExist, dontHaveAuthorizationToCreate, operationFailed... and we want the UI using this service to display different information messages depending which error occurred. In old java dev, we should have create all signed exception type and throw it in createObject. As Clean code says, it is forbidden to use Exception for business logic AND signed exceptions are evil... Why not...But i don't know how to solved this problem and i don't want to use return code. How do you do? Thanks for youre experience return.

  • SQL binary value to PHP variable leading zeros

    - by Agony
    Using sql query to pull data from a mssql database results in a value that still has leading zeros. The data in database is stored as binary(13) - so it will pull all 13 digits. However the value is a text, so any leading zeros will generally show up as '?' in a form on the site - and in return will update wrong data to the database later. So what i need is to only select/display the text itself, not all 13 bytes. using: SELECT CONVERT(char,uilock_pw) AS uipwd FROM tbl_UserAccount or SELECT uilock_pw FROM tbl_UserAccount still adds the leading zeros to the char array. Example in database: 0x71776531323300000000000000 Would show up as: qwe123??????? But should be: qwe123 Im not even sure what character those ? represent. Using Echo results in a normal qwe123 - but not in a form.

  • Image caching when rendering the same images on different pages

    - by HelpNeeder
    I'm told to think about caching of images that will be displayed on the page. The images will be repeated throughout the website on different pages and I'm told to figure out the best way to cache these images. There could be few to dozen of images on single page. Here's few questions: Will browser caching work to display the same images across different web pages? Should I rather store images in stringified form in a memory instead, using JavaScript arrays? Store them on hard drive using 'localStorage'? What would be easiest yet best option for this? Are there any other alternatives? How to force cache? Any other information would be greatly appreciated...

  • Why do my window titles lag behind the window contents?

    - by user8758
    The window title displayed in my maverick is often for the previous window. This is most noticeable in Firefox after using the back key to go to the previous window, but it also happens in file search and various media players. This even occurs in brand new installs of maverick and linux mint 10, so I know it has nothing to do with any configuration file snafu. I am using a Toshiba Satellite notebook with Intel graphics. Oddly enough, linux mint does not display this glitch when running in virtualbox (don't know about maverick in vbox). Any help with this issue would be greatly appreciated.

  • Problems booting Ubuntu 10.10 with Nvdia GeForce 6600gt

    - by SlyrNemesis
    I am quite new to Ubuntu and I already stumbled upon a problem. I run Ubuntu 10.10 Maverick Meerkat now and Install went fine, when trying to boot the screen popped black and I faced this message "gpu lockup - switching to software fbcon." When setting the display to onboard VGA through BIOS Ubuntu has no problem at all, but when I switch back to my AGP card (which is a Nvidia GeForce 6600GT) I get that message again. I do not use VGA for that card I use my DVI cable for it. Does anyone have an answer for me to make this work? Thank you

  • How can I generate filesystem images that are usable on many different virtualization systems?

    - by Mark Longair
    I have written a script that generates a root filesystem image (based on Debian lenny) suitable for User-Mode Linux. (Essentially this script creates a filesystem image, mounts it with a loop device, uses debootstrap to create a lenny install, sets up a static IP for TUN/TAP networking, adds public keys for login by SSH and installs a web application.) These filesystem images work pretty well with UML, but it would be nice to be able to generate similar images that people can use on alternative virtualization software, and I'm not familiar with these options at all. In particular, since the idea is to use this image as a standalone server for testing the web application, it's important that the networking works. I wonder if anyone can suggest what would be involved in customizing such root filesystem images such that they could be used with other virtualization software, such as VMware, Xen or as an Amazon EC2 instance? Two particular concerns are: If such systems don't use a raw filesystem image (e.g. they need headers with metadata or are compressed in some particular way) do there exist tools to convert between the different formats? I assume that in the filesystem, at least /etc/network/interfaces will have to be customized, but are more involved changes likely to be necessary? Many thanks for any suggestions...

  • Steam not opening or responding at all

    - by user109409
    The steam client won't open nor does it display any error message. I have tried right click > Games. I ran steam steam://open/games command, but the client just does not respond. Removing it with apt-get remove steam, deleting the Steam directory & the .deb file and reinstalling it, did not work either. This problem only occurred after I used killall steam.sh to force quit it, it was working fine before. I'm running 12.10 on a 64bit laptop with no additional drivers installed. Anyone else have this problem and a possible workaround? Thank you

  • Compiz cube issues since upgrading to 12.10. The caps and 3d windows are all over the place.

    - by Slarty
    I think it's due to residual settings from the old reflection and deformation plug in. I've attempted a complete reset of the settings and still no go though. The cube caps stay black and glitch out when I spin it etc and I see multiple copies of each window. It's like it's trying to display the "inside the cube" setting and the regular just floating 3d window at the same time. Here's one example (rep isn't high enough yet for fancy img imbed, sorry) http://i.stack.imgur.com/rrbBd.jpg Any ideas? I'm trying this on my desktop which is using an NVIDIA 8800 GTS card. I also tried it on an older laptop that uses an intel card and same deal. I think maybe I can use the dconftool and try to see if there are still settings from the deformation and reflection plug in causing this. Unless someone knows how to get that back (either a beta or an old version) somehow?

  • Android Java: Way to effectively pause system time while debugging?

    - by TheMaster42
    In my project, I call nanoTime and use that to get a deltaTime which I pass to my entities and animations. However, while debugging (for example, stepping through my code), the system time on my phone is happily chugging along, so it's impossible to look at, say, two sequential frames of data in the debugger (since by the time I'm done looking at the first frame, the system time has continued to move ahead by seconds or even minutes). Is there a programming practice or method to pause the system clock (or a way for my code to intercept and fake my deltaTime) whenever I pause execution from the debugger? Additional Information: I'm using Eclipse Classic with the ADT plugin and a Samsung SII, coding in Java. My code invoking nanoTime: http://pastebin.com/0ZciyBtN I do all display via a Canvas object (2D sprites and animations).

  • Problem with connecting two different networks

    - by tanascius
    I have two networks: 192.168.13.0/24 (blue) and 192.168.15.0/24 (green). Computer A is connected to the 13-net, only. Computer B has two interfaces, one in each network. There is third computer that acts like a router and connects the 13-net to the 15-net (only in this direction). Now, I'd like to ping 192.168.15.100 from computer A to B. Unfortunately there is never a reply. But when I use a hub instead of a switch it works. In my opinion the ping packet travels through the switch to the router (which is the default route/gateway for A). The router sends the packet back to the switch to B. Probably B receives it on its 15-net interface but answers with it's 15th interface? Is this possible? The problem is, that B may have only a gateway 192.168.13.50 - but I am not really sure of it (B is a embedded system with limited configuration possibilities). Can anyone explain what happens here? Thank you!

  • iptables, forward traffic for ip not active on the host itself

    - by gucki
    I have kvm guest which's netword card is conntected to the host using a tap device. The tap device is part of a bridge on the host together with eth0 so it can access the public network. So far everything works, the guest can access the public network and it can be accessed from the public network. Now the kvm process on the host provides a vnc server for the guest which listens on 127.0.0.1:5901 on the host. Is there any way to make this vnc server accessible by the ip address which the guest is using (ex. 192.168.0.249), without interrupting the guest from using the same ip (port 5901 is not used by the guest)? It should also work when the guest is not using any ip address at all. So basically I just want to fake IP xx is on the host and only answer/ forward traffic to port 5901 to the host itself. I tried using this NAT rule on the host, but it doesn't work. Ip forwarding is enabled at the host. iptables -t nat -A PREROUTING -p tcp --dst 192.168.0.249 --dport 5901 -j DNAT --to-destination 127.0.0.1:5901 I assume this is because the IP 192.168.0.249 is not not bound to any interfaces and so no ARP requests for it get answered and so no packets for this IP arrive at the host. How can make it work? :)
