  • exim4: multiple domains/IPs

    - by ButterdBread
    On my VPS I have 3 IPs which all have their own domain and their own reverse-DNS records. I have a website on each domain, sending emails. The problem is: the emails are rejected by many hosts because the reverse dns doesn't fit the host in the helo. All the emails are sent from the primary IP and therefore only one of the three domains work. I am looking for a way for exim to check which email adress i'm using to send the email and adapt the domain/IP transmitted in the helo. I have already tried many configurations but nothing has worked up to now. Simply changing MX-Records is impossible too, as I recieve (and also send) email via gmail and I don't want to set up my own webmail. Does anyone know a solution?

  • How do I disable spell checking in IE 11 (Win 8.1)?

    - by ComFreek
    My issue is similar to the one mentioned here: Disable spell checking in Internet Explorer 10 (Windows 8) I am using Windows 8.1 Pro 64-bit What I've tried already: Deactivating the spelling options: From the following, borrowed screenshot from the old Windows 8 (my interface is German, therefore I couldn't create one myself), I have turned both options off and restarted IE. It's still "correcting" my texts. Searching for 'spelling correction' addons: The indicated option in the following borrowed screensnot does not exist on my PC. Is there any way of disabling it? I prefer a canonical solution if one is available. If not, I am also interested in registry hacks or other solutions.

  • Pasting into Vista cmd.exe broke, why?

    - by Michel de Ruiter
    I use Windows Vista x64 and regularly use the command line window CMD.EXE. I have enabled QuickEdit Mode (and Insert Mode and AutoComplete), to be able to quickly copy and paste text. Copying (select block, Enter) works fine. Pasting (right click) text also works, as long as it has been copied inside a CMD.EXE window. When I copied the text somewhere else (in an editor, browser or whatever) however, pasting into CMD.EXE does not work! :-( Using the menu to Edit, Paste does not do anything either, so it's not a mouse thing. I also tried elevating CMD.EXE. I can copy/paste freely between CMD.EXE instances of all sorts: elevated/normal, x64/x86... I'm sure it did work on this machine until relatively recently. What could have happened? Some Windows Update perhaps? The problem has been reported by others, but without a solution.

  • Am I programming too slow?

    - by Jonn
    I've only been a year in the industry and I've had some problems making estimates for specific tasks. Before you close this, yes, I've already read this: http://programmers.stackexchange.com/questions/648/how-to-respond-when-you-are-asked-for-an-estimate and that's about the same problem I'm having. But I'm looking for a more specific gauge of experiences, something quantifiable or probably other programmer's average performances which I should aim for and base my estimates. The answers range from weeks, and I was looking more for an answer on the level of a task assigned for a day or so. (Note that this doesn't include submitting for QA or documentations, just the actual development time from writing tests if I used TDD, to making the page, before having it submitted to testing) My current rate right now is as follows (on ASP.NET webforms): Right now, I'm able to develop a simple data entry page with a grid listing (no complex logic, just Creating and Reading) on an already built architecture, given one full day's (8 hours) time. Adding complex functionality, and Update and Delete pages add another full day to the task. If I have to start the page from scratch (no solution, no existing website) it takes me another full day. (Not always) but if I encounter something new or haven't done yet it takes me another full day. Whenever I make an estimate that's longer than the expected I feel that others think that I'm lagging a lot behind everyone else. I'm just concerned as there have been expectations that when it's just one page it should take me no more than a full day. Yes, there definitely is more room for improvement. There always is. I have a lot to learn. But I would like to know if my current rate is way too slow, just average, or average for someone no longer than a year in the industry.

  • How can I avoid heroku stopping my dyno?

    - by iwein
    I build MVP's for clients regularly. Often I deploy on Heroku so they can see if the product works and demo it to prospects and investors. Then I have an application deployed on heroku, and it works like a charm, if not for one little thing. The app takes about 30 seconds to start up and heroku has the annoying habit of killing dyno's if they don't get traffic. My client is using the application for demo purposes now, so the load is extremely low and intermittent. I'm looking for a solution that is preferably: cost effective can be applied to multiple apps simultaneously What is the best way to avoid having the first request taking 30 seconds?

  • Bridging two connections in windows 7

    - by Serban Razvan
    I have recently bought an Samsung UE32ES5500 and I want to connect it to the internet. Not wanting to buy an expensive Samsung wireless adapter for the TV, I've decided to use an ethernet cable. Because the Internet cable passes through underground to the bedroom and the TV is located in the living room, i decided to put a router in the bedroom, and receive it's signal in the living room using a windows 7 laptop. Afterwards I connected the laptop to the TV through an ethernet cable, and bridged the two connections in Network Connections in Control Panel on the laptop. The TV successfully finds the laptop (and the router I think) but still cannot connect to the internet. Does anyone knows a solution to this problem? (the connections must be bridged because I want to have only one network in the house)

  • Trick Ubuntu into resolving a domain name locally

    - by Matthew Brown
    I have an Ubuntu box that I use for all sorts of things. One thing I really want to do is redirect a sub domain to a local script. For example thisbit.example.com should actually show the content from localhost/~USER/FAKE.thisbit.example.com/ which is a folder that Apache is running for me which contains a very simple PHP script which implements an offline version of a server script that I am testing against. But example.com should continue to behave normally as should notthisbit.example.com etc. Ideally I need to be able to switch from testing to live with minimal fuss when the time comes.

  • Windows Media Center won't Play MSN Video Player

    - by Chris Spicer
    My install of Windows Media Center won't play MSN Video Player videos. They appear in the main guide, but when I click on them, nothing happens. If I look on the main menu, I don't have any icons for MSN Video player there. People have suggested I try downloading updates, but that makes no difference. I have internet connectivity. My region is set to the UK (which is where I am). If I navigate to the MSN Video Player using Internet Explorer, the videos play fine. The machine is an Acer Revo RL100, running Windows 7 64-bit. Does anyone have a solution for this? Any help would be gratefully received.

  • Randomly and uniquely iterating over a range

    - by Synetech
    Say you have a range of values (or anything else) and you want to iterate over the range and stop at some indeterminate point. Because the stopping value could be anywhere in the range, iterating sequentially is no good because it causes the early values to be accessed more often than later values (which is bad for things that wear out), and also because it reduces performance since it must traverse extra values. Randomly iterating is better because it will (on average) increase the hit-rate so that fewer values have to be accessed before finding the right one, and also distribute the accesses more evenly (again, on average). The problem is that the standard method of randomly jumping around will result in values being accessed multiple times, and has no automatic way of determining when each value has been checked and thus the whole range has been exhausted. One simplified and contrived solution could be to make a list of each value, pick one at random, then remove it. Each time through the loop, you pick one fromt he set of remaining items. Unfortunately this only works for small lists. As a (forced) example, say you are creating a game where the program tries to guess what number you picked and shows how many guess it took. The range is between 0-255 and instead of asking Is it 0? Is it 1? Is it 2?…, you have it guess randomly. You could create a list of 255 numbers, pick randomly and remove it. But what if the range was between 0-232? You can’t really create a 4-billion item list. I’ve seen a couple of implementations RNGs that are supposed to provide a uniform distribution, but none that area also supposed to be unique, i.e., no repeated values. So is there a practical way to randomly, and uniquely iterate over a range?

  • Optimal way to make MySQL backups for fairly large databases (MyISAM / InnoDB)

    - by WinkyWolly
    Currently we have one beefy MySQL database that runs a couple of high traffic Django based websites as well as some e-commerce websites of decent size. As a result we have a fair amount of large databases using both InnoDB and MyISAM tables. Unfortunately we've recently hit a wall due to the amount of traffic so I've setup another master server to help alleviate reads / backups. Now at the moment I simply use mysqldump with a few arguments and it's proven to be fine.. until now. Obviously mysqldump is a slow quick method however I believe we've outgrown its use. I now need a good alternative and have been looking into utilizing Maatkits mk-parallel-dump utility or an LVM snapshot solution. Succinct short version: I have a fairly large MySQL databases I need to backup Current method using mysqldump is inefficient and slow (causing issues) Looking into something such as mk-parallel-dump or LVM snapshots Any recommendations or ideas would be appreciated - since I have to re-do how we're doing things I rather have it done properly / most efficient :).

  • erratic audio levels on windows vista

    - by old retired dude
    I'm somewhat hard of hearing. I've been listening to my windows Vista machine with a pair of headphones so I don't annoy the others. I have 2 issues: 1) the volume varies enormously depending on the source. Having a windows alert occur while I am listening to a DVD or Youtube is a painful experience. Is there a preferred way to set all the different audio controls so I have a more constant volume? I already have lowered the volumes of the windows alerts. 2)Is there a way to limit the volume of my headphones to protect what is left of my hearing? Is there a software solution or should I be going for a hardware limiter? thanks retired dude

  • Laptop keyboard and touchpad disabled on startup

    - by JAM
    I use Ubuntu 14.04 LTS on my Toshiba Satellite L775D laptop. 14.04 is the only operating system installed. I am new to Linux and only barely scratching the surface of doing things in terminal. When I boot my laptop keyboard and touchpad are disabled (99.99% of the time) if I do nothing. The only direct effect I can have is to keep pressing the "numlock" key during boot when I notice the "numlock" light goes off. If I do this then I have a 95% chance of the keyboard and touchpad working when I am in the operating system. I am able to use my wireless mouse regardless. I have not seen any messages during boot. Previously I have tried playing with input method settings and utilities as well as language support settings. This same problem exists with the 12.... and 13... versions of ubuntu. With everything I have tried (from looking at other posts/suggestions) it seems I can have only a temporary effect. Please help me find a permanent solution to this problem. thank you.

  • Visual Studio 2010 haunted keyboard

    - by Ryan
    It seems the haunted keyboard is back in VS2010 ... after working on a web application for a short while I find that some keys just don't work, or are behaving like certain keys are stuck. This is only in VS, and I am definitely not triggering any keyboard changes in VS or Windows (I have disabled that in Windows) and I have reset my environment settings several times. Aargh! This is so frustrating ... anyone else getting this problem? Is there a solution?

  • Get system info from C program?

    - by Hamid
    I'm writing a little program in C that I want to use to output some system stats to my HD44780 16x2 character display. The system I'll be working with is a Debian ARM system and, although irrelevant, the display is on the GPIO header.(The system is a Raspberry Pi). As an initial (somewhat unambitious) attempt, I'd like to start with something simple like RAM and CPU usage (I'm new to C). I understand that if I make external command calls I need to fork() and execve() (or some equiv that will let me return the results), what I would like to know is how I go about getting the information I want in a nice clean format that I can use. Surely I will not have to call (for e.g); free -h And then use awk or similar to chop out the piece I want? There must be a cleaner way? The question should be seen as more of a generic, what is best practice for getting info about the system in C (the RAM/CPU usage are just an initial example).

  • Context Menu for Browser to download file to specific folder

    - by elcojon
    There is this website which has customized audio files for me. I would like to save them in a special folder. Now I don't want to select the "special folder" each time in the file-chooser dialogue of my browser. I would rather prefer to have a custom entry in the context menu when I right-click the download link. This context-menu-entry should do the trick and download the file to the predefined "special folder". How would I start about that? I am using Safari and Chrome. So a solution in either browser is fine. To get into the context menu of the browser, what kind of programming do I need to do? Is it an extension, plugin, etc.? Thanks

  • How to detect a touch on transparent area of an image in a (libgdx) stage?

    - by Usman
    Can some one please help to detect a touch on an image which I am using as an actor in a stage. The image is actually a long diagnol brush which has plenty of transparent area. The problem is when I touche the transparent area of the brush image it is also triggering the clicklistener of the image. I need the click listener should only be called when the finger actually touched the visible image not the area which is empty. I am using libgdx-0.9.4 libraries. Here is my simple piece of code. import com.badlogic.gdx.scenes.scene2d.ui.Image; import com.badlogic.gdx.scenes.scene2d.ui.ClickListener; Image brushImg = new Image(ImageCache.getTexture("brush")); brushImg.width = mStage.width()*0.75f; brushImg.height = mStage.height()*0.75f; brushImg.setClickListener(new ClickListener() { @Override public void click(Actor actor, float x, float y) { SoundFactory.play("brush"); }

  • Communicate from PC in internet to remote GSM device

    I have several remote devices that use GSM modem and gather data. I need to communicate with those devices from a PC station located in a office using the dial up connection. Is there a way to do this WITHOUT an additional GSM modem connected to that PC? Is there some way to accomplish PC to remote GSM device communication using e.g. VoIP or similar technology? I want to avoid installing an additional GSM modem in the office and use some software solution instead.

  • Recovering a deleted partition

    - by Kishore
    I had a dual boot PC running Ubuntu 12.04 and Windows 7. About a month back, I deleted the Ubuntu partition via the disk management utility (I do not remember whether or not I formatted the partition after performing this action). I ran into some grub issues and used lilo to solve the issue. I followed the simple instructions described in this blog post. I now realize that there were some files in the Ubuntu installation that I need. Of course, I backed up the data, but not this folder apparently. Is there any way to get the data back? I tried following the process suggested on another post on askubuntu (suggesting the use of TestDisk), but was not able to even install TestDisk. The live USB I use is running Ubuntu 12.04 and it does not have a synaptic package manager. Installing from the terminal does not work because even after I type: sudo apt-get update sudo apt-get upgrade the command: sudo apt-get install testdisk fails to work.

  • Ethernet port sleeping on PS3 running linux

    - by Doug
    My lab has a PS3 running Ubuntu Linux 9.04 Server Edition. After a period of a few hours with no use, the Ethernet connection (eth0) seems to go to sleep, causing the connection to be lost. Pinging or trying to SSH into the machine results in no response. The fix I've been using is to access the machine locally and restart it (trying to bring eth0 down then up doesn't seem to correct it). I've tried setting up an hourly cron job that runs on the PS3 and pings another machine just to create network activity, but this doesn't seem to solve the problem either. Update: The solution was to run the above cron job much more frequently: every 10 minutes works.

  • How to move an object along a circumference of another object?

    - by Lumis
    I am so out of math that it hurts, but for some of you this should be a piece of cake. I want to move an object around another along its ages or circumference on a simple circular path. At the moment my game algorithm knows how to move and position a sprite just at the edge of an obstacle and now it waits for the next point to move depending on various conditions. So the mathematical problem here is how to get (aX, aY) and (bX, bY) positions, when I know the Centre (cX, cY), the object position (oX, oY) and the distance required to move (d)

  • How to call a program and exit from the shell (the caller) when program is active?

    - by Jack
    I want to run a program with GUI, by typing into konsole: foo args … and exit from the shell (that's the caller) when the program (foo) is active. How do I this? Is there a Linux/Unix built-in command/program to do it? I'm not a shell-man, really. I know that it's possible by writing a small program in C or C++ (any other programming language with small I/O interface on POSIX) programming language with the fork() and one-of exec*() function family. It may take some time; I'll do it only if there is no native solution. Sorry for my bad English; it's not my native language. Also, not sure on tags, please edit for me, if I'm wrong. If it matters, I'm using OpenSUSE 10.x.

  • How to Get the Folder Name of USB Disk?

    - by Kate Moss' Open Space
    When an USB Disk plugs into CE/Mobile based device, how do you know the folder name of the mounting point? Usually, it should be "USB Disk" but it is really depends on how OS image builder; they may change the folder name for whatever reason. FindFirstFlashCard looks simple and promising, the drawback is it only available on Windows Mobile. In fact, these find flash card API set will enumerate all of the mountable file system which includes SD card, CF and etc that we don't expect to get. So I am going to introduce you another way via Storage Manager. Here is the steps.
