  • Reducing volume of an audio device on windows 7

    - by bdonlan
    I have a USB headset with a very loud amplifier, but low granularity in its gain control. In order to get comfortable audio, I have to reduce the individual application levels in the mixer to '1', and the master mixer to around '10'. Of course, new applications start out at '10', and immediately blast out my ears. Is there a way to add a filter to cut down the volume some so I can get better control of it? That is, reduce the volume of '100' so I can work within a reasonable range.

  • What exactly are Link Relation Values?

    - by bckpwrld
    From REST in Practice: Hypermedia and Systems Architecture: For computer-to-computer interactions, we advertise protocol information by embedding links in representations, much as we do with the human Web. To describe a link's purpose, we annotate it. Annotations indicate what the linked resource means to the current resource: “status of your coffee order” “payment” and so on. We call such annotated links hypermedia controls, reflecting their enhanced capabilities over raw URIs. ... link relation values, which describe the roles of linked resources ... Link relation values help consumers understand why they might want to activate a hypermedia control. They do so by indicating the role of the linked resource in the context of the current representation. I interpret the above quotes as saying that Hypermedia control contains both a link to a resource and an annotation describing the role of linked resource in the context of the current representation. And we call this annotation ( which describes the role of linked resource ) a link relation value. Is my assumption correct or does the term link relation value actually describe something different? Thank you

  • Making Windows 7 default to "All Files" when opening a document?

    - by krebshack
    I'm taking over an old coworkers job and part of that means I'll be working on various IFS tickets without any real ERP experience. I'm working with one user who is trying to check in documents in IFS. Right now, IFS defaults to JPEGs and then she has to select "All Files" in order find PDFs. Example: http://i.imgur.com/xK0iAfF.png As much as I'd like to say "it's one extra step, come on" the user's manager has insisted it interrupts her workflow and asked us to get on it. I've spoken with our IFS experts and they're unaware of any setting that would make the open dialog default to All Files in IFS. I've searched in Google for any setting in Windows 7 that would do that - but those have been unsuccessful - I keep getting results about changing which program opens a specific file type.

  • systemctl (Fedora 17) and interacting spawned processes's consoles

    - by Sean
    Introduction I've recently upgraded to Fedora 17 and I'm getting used to the newer systemctl daemon manager versus shell init scripts. A feature I need on some of my daemons is the ability to interact with their consoles because unclean shutdowns not initiated by the process itself can cause database corruption. So, performing a systemctl stop service-name.service for example might cause irreversible data loss. These consoles read user input through stdin or similar methods, so what I've been doing on my old OS is to place those daemons foregrounded in a screen session, and I suspended that screen session with ^A ^z. It's also worth noting that I've now made systemctl do this automatically if the computer reboots, but it still doesn't solve my potential data corruption problem I'm trying to avoid. My Question Is there a way to use systemctl in order to directly interact with the console of processes it spawns? Can I hook a process through systemctl to get access to its console? Thanks You guys always give great answers, so I'm turning to you!

  • OpenGL, objects disappear at a certain z distance

    - by smoth190
    I'm writing a managed OpenGL library in C++, and I'm having a pretty annoying problem. Whenever I set an objects position to -2.0 or lower, the object disappears. And at distances 0 through -1.9, it doesn't appear to move away from them camera. I have a world matrix (which is multiplied by the objects position to move it), a view matrix (which is just the identity matrix currently) and a projection matrix, which is setup like this: FOV: 45.0f Aspect Ratio: 1 zNear: 0.1f zFar: 100.0f using GLMs glm::perspective method. The order the matrices are multiplied by in the shader is world, view, projection, then position. I can move the object along the X and Y axis perfectly fine. I have depth testing enabled, using GL_LEQUAL. I can change the actually vertices positions to anything I want, and they move away from the camera or towards it perfectly fine. It just seems to be the world matrix acting up. I'm using glm::mat4 for the world matrix, and glm::vec3 for positions. Whats going on here? I'm also using OpenGL 3.1, GLSL version 140 (1.4?).

  • Conflicts between 2 NICs

    - by funbi_grace
    Hi, I have an HP server (Windows server 2003) with 2 external NICs (couldn't get the builtin NIC to work). One is for an internal network of 4 PCs and the other is for part of an Internet-facing network. Many times a day, we have to disable the internal NIC in order to get the other NIC to see the network. I know this is happening on a server, but the issue is more related to the conflicts on the NICs. Any suggestions from the community on where to look for a solution?

  • When creating a GUI wizard, should all pages/tabs be of the same size? [closed]

    - by Job
    I understand that some libraries would force me to, but my question is general. If I have a set of buttons at the bottom: Back, Next, Cancel?, (other?), then should their location ever change? If the answer is no, then what do I do about pages with little content? Do I stretch things? Place them in the lone upper left corner? According to Steve Krug, it does not make sense to add anything to GUI that does not need to be there. I understand that there are different approaches to wizards - some have tabs, others do not. Some tabs are lined horizontally at the top; others - vertically on the left. Some do not show pages/tabs, and are simply sequences of dialogs. This is probably a must when the wizard is "non-linear", e.g. some earlier choices can result in branching. Either way the problem is the same - sacrifice on the consistency of the "big picture" (outline of the page/tab + location of buttons), or the consistency of details (some tabs might be somewhat packed; others having very little content). A third choice, I suppose is putting extra effort in the content in order to make sure that organizing the content such that it is more or less evenly distributed from page to page. However, this can be difficult to do (say, when the very first tab contains only a choice of three things, and then branches off from there; there are probably other examples), and hard to maintain this balance if any of the content changes later. Can you recommend a good approach? A link to a relevant good blog post or a chapter of a book is also welcome. Let me know if you have questions.

  • How do I create the "Gnome-Desktop-Item-Edit" program's launch icon with root privileges and more?

    - by GanZ
    I personally dont prefer running commands in terminal to achieve a task and prefer apps to execute the job. Creating launcher for apps is one such command where I prefer the gnome-desktop-item-edit application for creating launchers. If the gnome package is installed, just searching "create launcher" opens the app. But, it doesnt serve any purpose, because for starters the application cannot create launchers for various apps without root permission and the location where the apps have to be created. Usually the launcher apps with root permission can be created at /usr/share/applications and without root permission at /.local/share/applications. I dont prefer the latter location as it is vulnerable to deletion. Hence, in order to create the launchers through gnome with root, everytime I am forced to open this through terminal using the below command! $ sudo gnome-desktop-item-edit ~/.local/share/applications --create-new I dont want to open terminal everytime I want to create an application launcher on unity! I am able to lock the "Create Launcher" App in the Launcher, but not with root privileges So I want to be able to create the "Create Launcher" app shortcut on unity with default root privileges and for the app to create the launchers at usr/share/applications by default! Please help! P.S. I dont have enough rep points to add screenshots to help with the question!

  • User WinWget to keep web site alive in a Windows Server 2003

    - by Menelaos Vergis
    I have a site that must stay alive due to a service that runs and check a directory for changes. The site is running in IIS at a Windows Server 2003 and the solution I came up it that I will Schedule a task that requests the home page every 5 minutes. I am sure that this way the site will stay alive almost all the time. I have downloaded Wget from Wget from Windows and I have installed it at my windows server 2003 but I don't know how to use it in order to ping the server but not download anything. Since I want to use this forever I don't want to save anything on the disk, can you provide me with the command that pings a web page but don't save anything on the disk?

  • What's the best way to handle numerous recurring log entries in game loop?

    - by Kaa
    I have a custom logging system, use of which is scattered all over the engine and game. The system is linked to a "LogStore" that has an std::vector<string> logs[NUM_LOG_TYPES] - each vector corresponds with it's log type (info, error, debug, etc.). There's one extra std::vector that has "coordinates" to all log entries in the order they were received. Now, all the logging output is also displayed inside my development console in the game. The game console is handled by HTML-type GUI and therefore requires a new <p> element being added for each log output. My problem is that the log entries that are generated in the main loop each frame freeze the engine, because they continue to add elements to the in-game console, and if the console or guy generates a warning - that creates an infinite logging loop. I want to solve it by handling the recurring log entries in an elegant way that lets you know that something is critically wrong, but won't freeze the engine - like displaying the count of errors in the last 60 frames instead of displaying errors themselves. But how do you guys handle this? Does anyone know any nifty tricks to do this? I understand the question may sound vague, but if someone came across this type of issue I'm sure they would know exactly what's happening. Example problematic log entries: OpenGL warnings (I actually do check for errors every frame in many places) Really any prints anywhere in the main loop (may be debugging, may be warnings)

  • Grub2 cannot detect Windows 8

    - by MetaChrome
    At installation it did not detect Windows. I mounted the Windows partition and have run os-prober with no results returning. I am able to boot Windows or Ubuntu by specifying the partition in UEFI boot order. The bios does not appear to allow booting with legacy. SecureBoot is on. This is with Ubuntu 12.04 LTS on a Inspiron 15. Here is the gdisk: 1 2048 1026047 500.0 MiB EF00 EFI system partition 2 1026048 1107967 40.0 MiB FFFF Basic data partition 3 1107968 1370111 128.0 MiB 0C01 Microsoft reserved part 4 1370112 2394111 500.0 MiB 2700 Basic data partition 5 2394112 544743423 258.6 GiB 0700 Basic data partition 6 606183424 625140399 9.0 GiB 2700 Microsoft recovery part 7 544743424 545230847 238.0 MiB 0700 (/boot) 8 545230848 556949503 5.6 GiB 8200 (swap) 9 556949504 606181375 23.5 GiB 0700 (/) When installing ubuntu, I believe I specified that the bootloader be installed on /dev/sda. I added the following to /etc/grub.d/40_custom but booting ubuntu did not offer a grub menu: menuentry "Windows 8" { set root = "(hd0,4)" chainloader +1 } When booting I think I see "EFI Disk error" flash very quickly before Ubuntu starts booting.

  • How can I make a non-destructive copy of a (NTFS) partition?

    - by violet313
    I want to recover some deleted files from a healthy NTFS partition on an undamaged hard-disk. In order to leave the partition undisturbed, i plan to use dd to clone the partition to a raw image file & then attempt recovery from that mounted clone. Will dd if=/dev/sd<xn> of=/path/to/output.img perform a non-destructive copy ? Is attempting a restore from a clone using dd the best approach? [edit, wrt Deltiks answer, i need to be a bit clearer about what i'm asking] eg: are there some s/w that can do something more with the original sectors ? eg: if it was a damaged hard-disk i am aware that any kind of read is potentially destructive. but assuming my disk head is not going to suddenly spaz out etc, am i reducing my chances of a successful recovery (at any cost) by using an apparently non-destructive single read of my undamaged hard-disk. (btw: i am planning on using ntfsundelete & testdisk for recovery)

  • VirtualBox VRDP server doesn't start on Windows

    - by quanticle
    I've installed VirtualBox 4.1.8 on a Windows 7 Ultimate host system. I've set up an Arch Linux VM that starts just fine from the VirtualBox GUI. However, when I try to start it with VBoxHeadless --startvm <vm_name> it prints the following Oracle VM VirtualBox Headless Interface 4.1.6 (C) 2008-2011 Oracle Corporation All rights reserved. and then it just sits there. I never get the VRDE server is listening on port 3389 message like when I start a headless VM on a Linux machine. Do I have to configure anything else in order to get the VRDE server to run?

  • Shutdown button doesn't work in Windows 8

    - by Yob
    Some time ago I installed Windows 8 64bit ready-to-market version (as a student I had access to it before premiere). What I discovered is that the "shutdown" button doesn't work. When I want to shutdown the computer it simply logs me out. In order to turn off my machine I have to click "restart" and then simply press the poweroff button. I installed some updates but this issue is still not resolved. Is there any way to shutdown the computer in a normal way?

  • When a co-worker asks you to teach him what you know, do you share the information or keep it to yourself? [closed]

    - by Chuck
    I am the only developer/DBA in a small IT department. There is another guy who can do it, but he's more of a backup as he spends his time working on IT support stuff. Anyway we have a new hire and I've been training him on the IT support side of things. Seems like he is eager to learn and be productive, but nobody is going out of their way to show him anything. He's been asking me to teach him database design, SQL, etc. For some reason, the boss has him working with me. He is also sending him to meetings that I go to, yet he hasn't said outright that I have to teach him anything. Meanwhile, the boss insists on doing a lot of the support work himself (i.e. he hoards information and doesn't delegate to anyone). I'm a little bit on the fence. First, the new guy doesn't yet have a strong foundation on the IT support functions which is where we really need help at this time. Second, I paid thousands of dollars for classes and spent many hours learning this stuff. Is it my responsibility to teach others skills that I had to learn on my own? Others here really aren't quick to share information so I'm not sure that I should either in this environment. I do know that if I get him involved, and get him started on projects, then I'd be responsible for his mistakes. I had to take the heat for the other guy when he made mistakes. OTOH the guy wants to learn something, is motivated, and I don't want to stop him. We've had our share of slackers in the group and it's nice to have someone who is willing to work for a change. So what would you guys do? Would you teach him the skills that you spent all of that time learning? Set him up with a test database on his PC and recommend some books for him? Encourage him to get a strong foundation in IT support first and ask later? We haven't had a new hire in years, let alone one that is interested in what I do, so this is new to me.

  • Where can I find a good, tab-less privacy filter for my monitor?

    - by KeyStroke
    Hi, I have an ASUS laptop with a 14" monitor (12" by 7" to be more specific), and I've been looking for a decent privacy filter that I can use with for, yet I couldn't find any. The problem with the filters I've found is that they all use those ugly "tabs" that you have to stick on the sides of your monitor in order to slip the filter in. I'm looking for ones that are like HP privacy filter, where parts of it goes under the frame of the monitor to hold it in place. Too bad HP doesn't sell filters that fit my screen. So, any idea where I can get a good privacy filter? Your help is so much appreciated

  • Snort monitoring of spanning interface

    - by aHunter
    I have configured a Cisco 3500 switch with a port SPAN and have my snort node (fedora 13) plugged into it. I am running snort as a daemon and have configured a rule to log all tcp traffic but I am only seeing traffic with a destination of the snort node. I know that the SPAN port is working and wanted to know if there is a specific option that I needed to start snort with in order for it to pickup all the traffic? Or is there something that I have missed here? Many thanks.

  • How to Activate wifi in Toshiba Satellite C655?

    - by user4106
    I've recently bought a Toshiba Satellite C655. It came with Windows 7 preinstalled. I've never had a notebook before, but as a desktop user, I was a Ubuntu user since 2 years, and I've never had a problem with drivers, wifi, etc. When I tried to install the Ubuntu 10.04, and also the new and fresh 10.10, in my new laptop, I experienced some troubles with some of the componentes of my computer. For example, I was not able to activate my wi-fi card, although I know the kernel recognizes it correctly, because when doing "lspci" at the terminal, it was listed. Anyhow, I'm not able to "activate" the wifi, or whatever it's necessary to do in order to be able to search for public networks available, and to connect with them. The wifi-card the laptops brings is the (the lspci output): 03:00.0 Network Controller: Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) [168c:002b] (rev 01). It's anything in you can help me? Thanks a lot in advance! Edit Neither solution seems to work. In first place, i've tried installig what hhlp told me. After the installation, nothing seems to change: on right-clicking the wireless icon, it seems to recognize the card, because the option "Enable wifi" was ticked. But, once again, i was not able to "turn the wi-fi" on. In second place, i didn't try installing the drives, because the card is already recongnized. The issue is that i cannot seem to turn it on! One thing i've probably missed is that the Toshiba cames with a windows sofntware that allows you to enable / disable the wifi tools. So, it does not have an external "button" to turn it off. I don't know if that's the problem, but i have the feeling that the issue may be aroud there: in how to turn ON the wifi-signal (or to verify if it's on or off) in my ubuntu.

  • SSD and HDD have window 7 recovery partition. Can I delete one to make room for ubuntu?

    - by Brian Ecker
    I'm trying to install ubuntu right now, and I've run into a problem. I have Windows 7 installed on my SSD, and I want to install ubuntu on my HDD, but I already have three partitions on my HDD. The partitions are two Recovery Partitions and one data partition. What I don't understand is why my data drive(the HDD) has recovery partitions for Windows 7? The same recovery partitions(or atleast I think they are the same. Same sizes, same names, same order) are on the SSD with the Windows 7 install. Can I safely delete the recovery partitions on the HDD? My other option, I think, is to put the boot partition for ubuntu on the SSD where I only have three partitions. Then I can put the other three logical partitions for ubuntu in an extended partition on the HDD. Can I do that, put the boot partition on one drive and the other partitions on another? Here is a picture of the partitions and I have circled the one I would like to delete to make room. http://imgur.com/XOpJQ

  • What do ptLineDist and relativeCCW do?

    - by Fasih Khatib
    I saw these methods in the Line2D Java Docs but did not understand what they do? Javadoc for ptLineDist says: Returns the distance from a point to this line. The distance measured is the distance between the specified point and the closest point on the infinitely-extended line defined by this Line2D. If the specified point intersects the line, this method returns 0.0 Doc for relativeCCW says: Returns an indicator of where the specified point (PX, PY) lies with respect to the line segment from (X1, Y1) to (X2, Y2). The return value can be either 1, -1, or 0 and indicates in which direction the specified line must pivot around its first endpoint, (X1, Y1), in order to point at the specified point (PX, PY). A return value of 1 indicates that the line segment must turn in the direction that takes the positive X axis towards the negative Y axis. In the default coordinate system used by Java 2D, this direction is counterclockwise. A return value of -1 indicates that the line segment must turn in the direction that takes the positive X axis towards the positive Y axis. In the default coordinate system, this direction is clockwise. A return value of 0 indicates that the point lies exactly on the line segment. Note that an indicator value of 0 is rare and not useful for determining colinearity because of floating point rounding issues. If the point is colinear with the line segment, but not between the endpoints, then the value will be -1 if the point lies "beyond (X1, Y1)" or 1 if the point lies "beyond (X2, Y2)".

  • The term "interface" in C++

    - by Flexo
    Java makes a clear distinction between class and interface. (I believe C# does also, but I have no experience with it). When writing C++ however there is no language enforced distinction between class and interface. Consequently I've always viewed interface as a workaround for the lack of multiple inheritance in Java. Making such a distinction feels arbitrary and meaningless in C++. I've always tended to go with the "write things in the most obvious way" approach, so if in C++ I've got what might be called an interface in Java, e.g.: class Foo { public: virtual void doStuff() = 0; ~Foo() = 0; }; and I then decided that most implementers of Foo wanted to share some common functionality I would probably write: class Foo { public: virtual void doStuff() = 0; ~Foo() {} protected: // If it needs this to do its thing: int internalHelperThing(int); // Or if it doesn't need the this pointer: static int someOtherHelper(int); }; Which then makes this not an interface in the Java sense anymore. Instead C++ has two important concepts, related to the same underlying inheritance problem: virtual inhertiance Classes with no member variables can occupy no extra space when used as a base "Base class subobjects may have zero size" Reference Of those I try to avoid #1 wherever possible - it's rare to encounter a scenario where that genuinely is the "cleanest" design. #2 is however a subtle, but important difference between my understanding of the term "interface" and the C++ language features. As a result of this I currently (almost) never refer to things as "interfaces" in C++ and talk in terms of base classes and their sizes. I would say that in the context of C++ "interface" is a misnomer. It has come to my attention though that not many people make such a distinction. Do I stand to lose anything by allowing (e.g. protected) non-virtual functions to exist within an "interface" in C++? (My feeling is the exactly the opposite - a more natural location for shared code) Is the term "interface" meaningful in C++ - does it imply only pure virtual or would it be fair to call C++ classes with no member variables an interface still?

  • Password History Storage and Variability Comparison

    - by z3ke
    I believe this situation would be similar to many others out there, so maybe some of you can shed some light... Supposedly, when making password changes through MS exchange every 90 days, you cannot use any simple variation of one of your old passwords, up to whatever limit the admin's set for a system. My question: If your previous passwords are only stored as hashes, how can they check for the "just changed one letter" case. Wouldn't they have to have access to the old plain-text passwords in order to make those comparisons? The only other thing I can think of is if upon original creation of a password, they also stored all other one character permutations of it, so that they can be banned later?

  • Should I indicate that the user exists or was deleted on the error page?

    - by animuson
    On an ordinary public website, the user's profile is always publicly visible to all visitors (such as Stack Overflow), where they can limit certain pieces of information via privacy settings or just removing the information. Now the user has decided to delete their account (in my case deactivate) so that their account doesn't technically "exist" anymore. The way my system is set up, when their account is deactivated, their username for any content connected to them just becomes "Anonymous User" as if it were a guest that posted. I feel like this could cause some confusion for other users. I'm also concerned about what kind of error to display when someone attempts to view their profile page. My gut tells me to just display a standard 404 page to hide the fact that they ever existed, but then you also have to consider that, since usernames must be unique, anyone can go to the register page and type in the username to see if it really exists or not. I have a similar problem with another website, which gives users the ability to hide their profiles from the public and only allow registered users to view it. Again it's with the dilemma of what kind of error message to display when an unregistered users attempts to view their profile with invalid permissions. So, would it be acceptable to display basic errors such as "user has been deactivated" or "you must be logged in to view this profile" in order to give other visitors some idea of why the page can't be displayed, or should I attempt to cover the user's privacy a little and just display a standard 404 without indicating in any way that the user might exist? Are there any other issues that I'm not realizing about either route? To go back to the beginning, should I even bother changing the user's name to "Anonymous User" when their account is deactivated? Would it be acceptable to just display a non-linked version of their username in place of the normal linked display name?

I know TextWrangler has a macro ability but I can't figure out a efficient way to do this. Since I have to do it so often I'd love to just have a simple keybinding or menu item to do this simple replace/find all for me. Anyone know how to do this? ^_^
