• Fixing Windows 7 hibernation

  - by 80skeys

  I've been mucking around with the partitions on my laptop (I'm an experienced Linux/grub guy) and have somehow ended up affecting the ability of Windows 7 to go into hibernate mode. All other functionality seems to be okay. But when I press Hibernate, it behaves as if it starts to (screen goes dark, a little disk activity) but never powers off and if I move the mouse the login screen instantly comes up. I don't know if Window uses a separate partition for hibernation? There is a 200MB partition on the drive - I seem to recall it was related to diagnostics or some other Windows- boot menu stuff. In any case, wondering if there's some commands I can run to restore the ability to hibernate and also which partitions need to be marked "active" and if there's anything I need to do to the MBR of the hard drive or the MBR of the Windows partition? As I said, Windows boots fine as long as it is designated the Active partition. I just need to fix Hibernation.

• Adding multiple vectors in R

  - by Elais

  I have a problem where I have to add thirty-three integer vectors of equal length from a dataset in R. I know the simple solution would be Vector1 + Vector2 + Vector3 +VectorN But I am sure there is a way to code this. Also some vectors have NA in place of integers so I need a way to skip those. I know this may be very basic but I am new to this.

• Youtube video processing on iPhone

  - by Chonch

  Hey In my iPhone app, I want to load a video from youtube, perform some basic image processing on it and display it to the user. I am using openCV to do my image processing, and I know I can use it for grabbing all of the frames from the video as well (cvRetrieveFrame). My only problem is that cvRetrieveFrame expects to get its source of type CvCapture* which can be created either by a camera source or by a file name. How can I set a youtube video file as the source for CvCapture*? Thanks,

• Remove CGI from IIS7

  - by jekcom

  I ran some security scan and the scan said that all kind of CGI stuff are potential thread. This is part of the result : (ash) is present in the cgi-bin directory (bash) is present in the cgi-bin directory By exploiting this vulnerability, a malicious user may be able to execute arbitrary commands on a remote system. In some cases, the hacker may be able to gain root level access to the system, in which case the hacker might be able to cause copious damage to the system, or use the system as a jumping off point to target other systems on the network for intrusion and/or denial of service attacks. and many more related to cgi-bin directory. First I searched all the server for cgi-bin folder and it did not find any. Second I'm running my website on pure .NET and I don't use any scripts like php. Question is how can I remove this CGI thing from the IIS?

• WPF Timeline Control

  Hi, I am looking for a WPF Timeline User Control. I have checked out Blendables Timeline and Animated Timeline control from IdentityMine, but it is rather basic and buggy. I am looking for a timeline control that is similar to the MIT Similie timeline. http://www.simile-widgets.org/timeline/ What i need to be able to do is add interactive objects to the timeline, for example video, images, etc. Any ideas?

• Alt, Meta and other modifier keys

  - by KAction

  I want to get more combos in Emacs, so I tried to bind Alt, Super, Hyper via modmap to keys. I failed at it. So I tried to use xdotool. I started emacs -Q for clean experiment. Pressed C-hC-c and executed in other terminal: xdotool key --window 119537875 "meta+x" xdotool key --window 119537875 "alt+x" Both commands resulted in M-x runs the command execute-extended-command. So, Emacs do not differ between Alt and Meta. How can I fix it?

  - by japs

  Hi all, I'm writing a Python+Qt4 application that would ideally need to pop up a window every once in a while, to display pdf documents and allow very basic operations, namely scrolling through the different pages and printing the document. I've found the reportLab to create pdf files, but nothing about pdf viewers. Does anyone knows anything that might help. i was really hoping for the existence of something like the QWebView widget... thanks in advance to all

• Printing Stdout In Command Line App Without Overwriting Pending User Input

  - by Chris S

  In a basic Unix-shell app, how would you print to stdout without disturbing any pending user input. e.g. Below is a simple Python app that echos user input. A thread running in the background prints a counter every 1 second. import threading, time class MyThread( threading.Thread ): running = False def run(self): self.running = True i = 0 while self.running: i += 1 time.sleep(1) print i t = MyThread() t.daemon = True t.start() try: while 1: inp = raw_input('command> ') print inp finally: t.running = False Note how the thread mangles the displayed user input as they type it (e.g. hell1o wo2rld3). How would you work around that, so that the shell writes a new line while preserving the line the user's currently typing on?

• javamail vs sendmail performance during bulk email

  - by Glenn2041

  Hi all, I'm writing a Java mass emailer application to send out emails to send between 50,000 to 100,000 a day to users. The current plan is to delegate the sending to delegate to sendmail (on the local unix server). From our testing sendmail is sending a maximum of 5 emails per second. Would JavaMail be a faster option? Does anyone know what a faster way to send emails. We want to get this process out as quick as possible. Edit: BTW, a pdf will be attached too

• Default shell for running scripts (w/o shebang) in macos?

  - by Igor Spasic

  I have ZSH as default shell in MacOS, everything is working fine. ZSH is installed as brew package, Ive set default shell in my account, new shell is listed in /etc/shells... everything is set, like I've said. I have some shell scripts in which I use some commands from zsh, like print. When I execute the script from command line, the print command is not recognized and the script fails. This script does not have the shebang line. When I put the shebang line for zsh, then everything works; the print command is working. Since I am using only ZSH, is it possible to set default shell for running scripts, so I don't have to put shebang line in my .zsh scripts? Or is it possible to associate .zsh extension to ZSH shell execution?

• Dynamips Virtual Router not pinging external host after bridging

  - by maiky

  I have setup a virtual router image with dynamips and setup bridging between tap0 interface of the virtual router and eth0 and br0 with commands [root@cisco_host]# brctl addbr br0 [root@cisco_host]# ifconfig br0 up [root@cisco_host]# ifconfig eth1 0.0.0.0 [root@cisco_host]# brctl addif br0 eth1 [root@cisco_host]# ifconfig br0 192.168.0.100 netmask 255.255.255.0 up In dynagen configuration I have: f0/0 = NIO_tap:tap0 So, [root@cisco_host]# brctl addif br0 tap0 [root@cisco_host]# ifconfig tap0 up router(config)#int fa0/0 router(config-if)#ip address 192.168.0.101 255.255.255.0 router(config-if)#no shutdown After the configuration above I was expecting that from inside the router I could ping an external machine with IP 192.168.0.1 Actually from the host I can ping the external host 192.168.0.1 as well as 192.168.0.100 and 192.168.0.101. So what am I missing here? tap0 is bridged with br0 and in turn with eth1. So why the router is not pingable from 192.168.0.1 and vice-versa??

• Native Windows Application Development Options

  - by Michael Stum

  Long winded title, short question: If one wants to develop for Windows but not have to rely on any external dependency (no runtime, thus ruling out .net), what supported, alive and fully functioning* alternatives are there? Visual Basic 6 is dead, Visual C++ is obvious and Delphi seems to be the prime choice for that, but I wonder if there are any other alternatives? *as in: Being able to use all the Windows Features like putting an icon in the Notification Area, making the Taskbar Icon flash etc.

• When using grep from VIM, how to jump to results?

  - by Marplesoft

  When using the grep plugin to VIM, I can search the current directory for all occurrences of a string within a set of files, like this: :grep Ryan *.txt This outputs something like this: file1.txt:3:Ryan was here file2.txt:10:Ryan likes VIM file3.txt:5:superuser.com is a fav of Ryan (1 of 3): Ryan was here Press ENTER or type command to continue If I press enter, it just takes me back to my editor. What I really want to do is be able to open up one of those files and jump to the place where the string was found. Is there a way to do this? The 1 of 3 part makes me think there's a way to tab through the results, but I don't know what commands are available to me. Can anybody shed some light on this?

• Failing to install activerecord-jdbcmysql-adapter gem

  I am trying to follow the basic "Create a blog in 20 minutes" Rails screencast but have hit a stumbling block already. When I try to rake db:migrate I get errors about the gem activerecord-jdbcmysql-adapter not being installed. When I try to install it, I am told it doesn't exist.

• Linux memory fragmentation

  - by Raghu

  Hi all, Is there a way to detect memory fragmentation on linux ? This is because on some long running servers I have noticed performance degradation and only after I restart process I see better performance. I noticed it more when using linux huge page support -- are huge pages in linux more prone to fragmentation ? I have looked at /proc/buddyinfo in particular. I want to know whether there are any better ways(not just CLI commands per se, any program or theoretical background would do) to look at it.

• Tomcat threads vs Java threads

  - by black666

  When using java threads, one has to take care of the basic problems that come with concurrency through synchronization etc. AFAIK Tomcat also works with threads to handle its workload. Why is it, that I don't have to think about making my code threadsafe when it is running in Tomcat?

• GCC without Xcode on OS X

  - by Konrad Rudolph

  I've just unwrapped my new MacBook Pro (yay!) and am now setting it up properly for development. Since I want to avoid clutter, I'm wondering if I really need to install the Xcode tools at all (I never use the IDE or Mac specific tools), since I'll install a newer version of GCC anyway, using MacPorts. So, is there any benefit in installing Xcode? Is it necessary? What kind of set-up does it do behind the scenes? Basically: can I skip this or will it come back to haunt me because some Unix development tools just assume that OS X is always set up in this way?

• How to get AMD Catalyst working on Arch x86_64

  - by gh403

  I've got a Dell Inspiron 15R 7520 with AMD's hybrid "PowerXpress" graphics. The integrated graphics card is (if I understand it correctly) integrated with the i7-3612QM processor, and the discrete graphics card is a "Southern Islands" Radeon HD 7730M. The integrated graphics work perfectly under Arch. However, the discrete graphics don't. I have tried several different methods, and the one that seems to get me the farthest with the least effort is the AUR package catalyst-total-pxp. After installing, rebooting, and issuing the commands # aticonfig --initial # pxp_switch_catalyst amd # X X completely fails to start. The X log can be found here. I don't understand what is failing; potentially, it has something to do with the way my card is hooked up--I think it's muxless, but I really don't know. What is the matter here? Any help would be appreciated.

• iproute2 rules and iptables NAT... what is the difference?

  - by Jakobud

  We have 2 different ISP connections. Our previous "IT guy" setup our firewall like so: When /etc/rc.local was executed on startup, it did a bunch of ip rule add and ip route add commands in order to route certain internal hosts to use certain ISP connections. Then at the end of /etc/rc.local, he executed our iptables firewall rules that were generated by Firewall Builder. These iptables rules have both Policy and NAT rules setup in them. What I don't understand, is why did he use iproute2 to specify rules and routes but also specify NAT rules for iptables? Why didn't he just do it all in one or the other instead of using them both? Could he have got rid of the iproute2 rules and routes and just put all those same rules into the iptables NAT settings?

• "Beveled" Shapes in Quartz 2D

  - by Shaggy Frog

  I'm familiar with some of the basics of Quartz 2D drawing, like drawing basic shapes and gradients and so on, but I'm not sure how to draw a shape with a "beveled" look, like this: Essentially we've got a shine on one corner, and maybe some shading in the opposite corner. I think -- I didn't make this image, although I'd like to be able to approximate it. Any ideas? This is on the iPhone, and I'd like to use built-in frameworks and avoid any external libraries if at all possible.

• Multiple Ubuntu Server SSH Connections

  - by Craig Smith

  I'm trialing a ubuntu server 12.04 LTS to replace a Windows Server that I use but I have got a little stuck with SSH I'm currently able to SSH into the server but I need to have multiple persistent SSH connections as I have at least 3 applications that need to run in the server and still be able to access their terminals to issue commands to the applications. At the moment this is fine if I use the physical terminals of the machine as I can just jump between the three terminals I use but remotely doing this is the issue. As I'm not entirely familiar with this side of linux I'm not sure if this is even possible to do or how to even get around this issue.
