• It's possible to use google smtp for sending email from my server?

  - by Magnetic_dud

  Well, I am becoming crazy to let my email deliver to gmail/hotmail from my new ip. Last year, i had no problems with my past ip, but now my emails go straight to the spam folder of gmail and hotmail. I checked with mxtoolbox.com and i am not blacklisted, not an open proxy, rdns is configured the right way, SPF policy is present on the DNS. My spf is v=spf1 a mx ~all But, still, I am filtered. So, I am wondering: since gmail does not accept my emails, it's possible to use gmail smtp server to deliver all mails from my server? AFAIK, it will change all the "from" address, but maybe there is a way to not let it happen?

• Postfix not delivering mails

  - by Sotocan

  Hi all, I have problems with a recently configured postfix MTA. When postfix starts the following warning appears: "postfix/qmgr[5078]: warning: connect to transport private/filter: No such file or directory" I have amavis-new as a content-filter, but even if I comment-out the relevant line, the warning appears. As a result (I think), of the above, I get errors like below, for every virtual domain that I have: "postfix/error[5080]: 254851834107: to=, relay=none, delay=13082, delays=13082/0.01/0/0.01, dsn=4.3.0, status=deferred (mail transport unavailable)" The good news for me, is that somehow I managed to fix that (don't ask me how!!!!) The problem is that now I have 50 or so mails, that were affected by the aforementioned problem, in the mail-queue... If I "postqueue -f " I get the same style of error as before (mail transport unavailable)...however new mails are delivered to their final destination properly... Any suggestions? Kind regards. P.S. Local mail delivery from/to Unix and virtual users, was OK write from the beginning!

• spurious hardware memory 'errors' on hp dl380 g5's being generated

  - by friedchicken

  Hi All, i've got 2 new HP dl380g5 servers running HP's esxi4 patched to 219382. they have both been patched up to the latest hp firmware levels (firmware cd 8.7) both are running 32gb (4 x 8gb sticks) both servers are showing the same symptoms - the memory lights come on for two (random) dimms on the front of the server and the health led turns red. sometimes the server stays up and running with no problems. othertimes the server locks dead and only a power reset can bring it back. there is nothing showing in the ilo logs and nothing within the vmware hardware monitoring. the memory has been replaced i've got other customers that have been running dl380g5's with out any issues on esx3.5 - this is our first vsphere deployment with them. these are meant to go live soon so any advice would be great. thanks in advance.

• What's the point of the Prototype design pattern?

  - by user1905391

  So I'm learning about design patterns in school. Many of them are silly little ideas, but nevertheless solve some recurring problems(singleton, adapters, asynchronous polling, ect). But today I was told about the so called 'Prototype' design pattern. I must be missing something, because I don't see any benefits from it. I've seen people online say it's faster than using "new"' but this is doesn't make any sense, since at some point, regardless how the new object is created, memory needs to be allocated for it ect. Furthermore, doesn't this pattern run in the same circles as the 'chicken or egg' problem? By this I mean, since the prototype pattern essentially is just cloning objects, at some point the original object must be created itself (ie, not cloned). So this would mean, that I would need to have an existing copy of every object that I would ever want to clone already ready to clone? Seems stupid to me. Can anyone explain what the use of this pattern is? Original post: http://stackoverflow.com/questions/13887704/whats-the-point-of-the-prototype-design-pattern

• Bad password when logging in via Remote Desktop

  - by Shiraz Bhaiji

  I have just setup a windows 2003 server running in hyper-V. When I log in via Hyper-V it works fine. When I try to login via remote desktop I get a bad user name or password error. I have: Disabled the firewall Enabled remote connections Before I did the above I did not get to the login screen. I can ping the ip address of the image. I am trying to login as Administrator. Anyone have an idea about how to fix this? Edit I have now managed to fix this by changing the password to something without special characters. Strange thing is the I could not see any problems with the passord, had tried typing it into the user name field to check it.

• Netbeans automatically changes the file owner when updating files

  - by Alon_A

  We use Netbeans IDE 7.2 to edit our PHP files. In the Run Configuration it is configured as Remote Web Site to automatically save the changes on our web server (Centos OS 6.3). The problem is that every time it is updating the files the owner of the file is changed from apache:apache to userThatUploadedTheFile:users. This causes us problems with SOAP cache files that are configured with apache:apache ownership, and we need to manually chownit back to apache:apache. We've checked the "Preserve Remote File Permissions" checkbox, so the permissions are not changed, only the owner. Is there any solution to preserve the ownership ?

• Ubuntu+Mono+Postgres+ASP.NET 4.0. No problem?

  - by wreck_of_u

  Would this be ok? I'm an ASP.NET developer and I'm planning to build "portable" web app servers based on Atom D510 mini-ITX. I have ran Ubuntu 10 with MySQL along with a separate IIS machines (win 2k3, 2k8) before with no problems. But now I'm thinking of "packaging" a web/db server into one small, cheap machine. I thought of Ubuntu/Mono/Postgres/ASP.NET, that it would be a good idea but I'm not sure? I have not actually tried it yet. Your thoughts?

• Wierd Windows File Share Behavior

  - by CT

  Scratching my head awhile on this. I'm on a Vista client trying to access a file share running on a Windows Server 2008 R2 box. Windows Active Directory Domain. The shares I am trying to access: \\Server1\FileShare1\Folder1\foo and \\Server1\FileShare1\Folder1\bar The client does not have any permissions at Folder1. The client has read permissions at folders foo and bar. In this example I can access \Server1\FileShare1\Folder1\foo but I get the following error when I try to access \Server1\FileShare1\Folder1\bar: "Network Error: Windows cannot access \Server1\FileShare1\Folder1\bar. Check the spelling of the name. Otherwise, there might be a problem with your network. To try to identify and resolve network problems, click Diagnose" I hit Diagnose. It returns with "Windows checked the path and '\Server1\FileShare1' is correct but 'Folder1' could not be found." What is going on? It finds Folder1 fine when going to \Server1\FileShare1\Folder1\foo.

• Browsing freezes after installing SP2 on Vista

  - by n21jc

  After installing SP2 on Vista 32-bit HP laptop, all browsers (Firefox, IE, Maxthon) periodically freeze randomly. It occurs when opening a new webpage. It might happen after 45 minutes of browsing, or 3 minutes. The only way to get out of it is to right click the taskbar, "end program", and say "close now" when it tries to search for a solution. Or occasionally, I have to hard reboot. It doesn't seem to correlate with any one particular type of webpage, but I'm assuming that something being loaded doesn't play well with my system. I would uninstall SP2, but it fixed several even more annoying system problems I'd had with my computer.

• Windows 2008 R2 on ESXi 4.1 cpu utilization kernel high

  - by MK.

  I have a Win2k8 guest running on ESXi 4.1. The host has 12 cores and the problem happens even if the guest is the only VM on the host. We have 4 cores dedicated to the guest. We noticed that network starts chocking when the CPU load goes up. After some testing we noticed that when running a simple CPU hogging tool set up to run 3 threads at 100% the regular CPU load goes to 75% like it should and the "kernel times" graph in task manager goes up to 25%. My intuition tells me that the network problem and kernel times problem are the same. This is confirmed by another similar VM we created on the same host which doesn't have either of the problems. VMWare tools are obviously installed. The nic is e1000. What else can we do to troubleshoot this?

• Choosing the correct network protocol for my type of game (its Wc3 Warlock style)

  - by Moritz

  I need to code a little game for a school project. The type of the game is like the Warcraft 3 map "Warlock", if anyone doesnt know it, here is a short description: up to ten players spawn into an arena filled with lava, the goal of each player is to push the other players into the lava with spells (basically variations of missiles, aoe nukes, moba spells etc) http://www.youtube.com/watch?v=c3PoO-gcJik&feature=related we need to provide multiplayer-support over the internet, for that reason I am looking for the best network protocol for this type of game (udp, tcp, lock step, client-server...) what the requirements are: - same/stable simulation on all clients - up to ten players - up to ~100 missiles on the field - very low latency since its reaction based (i dont know the method wc3 used, but it was playable with the old servers) what would be nice (if even possible, since the traffic might be too big): - support for soft bodies over the network (with bullet physics), but this is no real requirement I read several articles about the lock step method used for RTS games, this seems to be great, but does it fit for real-time action games too (ping-related)? If anyone has run into the same problems/questions like me, I would be very happy about any help

• dual boot ubuntu installation mishap

  - by user590849

  I have Windows 7 pc ,where i had 2 partitions, a c drive for my system files and a d drive for my data. I decided to install ubuntu 11.10 a couple of days ago and thought of install it in a separate partition of its own. So i made a separate Linux partition of 30GB. I downloaded ubuntu on my usb stick and installed. During the installation process i was asked where to install ubuntu so i opened up a screen that was similar to this one There were six partitions present ( I had made only 3 partition via windows). Their names were totally different from the ones that i had given in windows. So i selected a drive which had the same size as my Linux partition that i had made in windows ( no other partition had the same size). I clicked on install now and got an error message saying that "There was no root folder set". I set the newly made partition as my root folder and clicked install now. Now out of the 6 partitions that were created 3 were logical ( i had only created 3 partitions in windows). As soon as i clicked install now, the system asked me where i wanted to put my "swap space". I selected one of the logical drives and hit install. Ubuntu successfully installed on my system and at the end it asked me to reboot. I did and got the following error message: "missing operating system". I was shocked. I tried my windows recovery disk ( that i had gotten when i had purchased my laptop) and there i went into startup repair. In the startup repair option i was not able to locate windows. The system asked me to click the "Load drivers" button to load the drivers to my harddrive where windows was installed, but i could not locate any drivers to my harddrive. I tried this several times but to no success. I panicked and installed ubuntu, now this time click "ok" at every step( not worrying about the partition and all). The os installed correctly and i am now able to access my harddrive. NO data within the c drive is lost. All the windows system files are intact. I wish to recover my windows installation. How do i go about it? Thank you in advance. I do not want to format my computer and install windows again.

• Are there any tools for monitoring individual Apache virtual hosts in real-time?

  - by Dave Forgac

  I'm looking for a way to monitor and record Apache traffic, separated by virtual host. I am currently using Munin to capture this and other data for the entire server however I can't seem to find a way to do this by vhost. This link describes using a module called mod_watch which is apparently no longer in development: http://www.freshnet.org/wordpress/2007/03/08/monitoring-apaches-virtualhost-with-munin/ The file that is listed as being compatible with Apache 2.x is reported to have problems with missing vhosts an reporting data correctly. Does anyone know of a reliable way to determine real-time traffic per vhost? If I can find this it should be easy enough to write a new Munin plugin.

• F# &ndash; Converting your C# brain to the F# way

  - by MarkPearl

  My brain still thinks in C#!!! I have been looking at F# and trying to figure out the basics of it, but all the time in the back of my mind I am going – what is the C# equivalent to this or that… It’s frustrating because I almost want a F# to C# dictionary the whole time – and simply translate my C# code to F# – which would negate the main motivation for learning F# – as I want learn functional programming - if I was simply doing C# code in a F# syntax I would be gaining nothing! So I am experiencing pain while my brain forms some new neural networks… but luckily I live in a country where we have 11 official spoken languages, and plenty more unofficial languages so I have gone through the pain of learning how to speak a new language before – and I am finding the process is almost identical in learning a programming language that promotes a different way of looking at problems (from Object Orientated to Functional). That beings said… the first thing to learn is the basic syntax… I have searched the web for appropriate places to get a translation – and have been quite disappointed with what is out there for F#. Luckily, OCaml came to the rescue. There are some really good tutorials on getting started with OCaml syntax, one in particular that stood out was the OCamal-Tutorial. What I particularly like about it is that it is doing comparisons between C based languages and OCaml. Give it a read sometime – it’s well worth it and has definitely helped me understand F# a little better.

• Netbeans hard freezes Windows XP, how to debug

  - by Jestep

  I get this problem about once to twice a day while editing in netbeans. I will be editing some code in Netbeans and I get a hard freeze requiring a full reboot. There hasn't been any correlation with an actual event that I can tell. Sometimes it's when I focus, sometimes while typing, sometimes while clicking on another window. I need to figure out how to track down what's causing the problem, as no error is generated when this happens. No error in Netbeans logs or Windows logs. I've also tried letting it sit to see if it recovers, and it's definitely stuck. I haven't had any problems with other apps running JRE, so I'm thinking it's Netbeans itself. I can't submit a bug report because I can't get a log or any reproduce-able explanation of the problem.

• Windows 7 system CPU bogged by windows services, no explanation

  - by Alex

  I'm looking at a laptop for a colleague which is running terribly slow. A quick look showed that the CPU was 100% used by 2-3 SVCHost processes, which off course doesn't tell much since those are just 'cover' processes with services running underneath them. So I fired up process explorer in hopes of finding a shady rogue service which was bogging the system, but to my suprise I found genuine MS Windows processes (or at least damn-good disguised ones) are bogging down the system: dnscache (DNS Client) IKEEXT (IKE and AuthIP IPSec Keyring modules) iphlpsvc (IP Helper) Seen separately, these processes might seem odd to be using a lot of CPU, but taking a step back one can conclude that all three services are quite closely related to networking. I've tried running: netsh int ip reset log.txt which has helped me save bizarre network-related problems in the past, but this didn't help Off course I though about a virus, but both MS Security Essentials as well as malwarebytes (let both run a full scan).

• How can I make my PHP development environment more efficient?

  - by pixel

  I want to start a home-brew pet project in PHP. I've spent some time in my life developing in PHP and I've always felt it was hard to organize the development environment efficiently. In my previous PHP work, I've used a windows desktop machine and a linux server for development. This configuration had it's advantages: it's easy to configure Apache (and it's modules)/PHP/MySql on a linux box, and, at the time, this configuration was the same like on production server. However, I never successfully set up a debug connection between my Eclipse install and X-debug on server. Transferring files from my local workspace to the server was also very annoying (either ftp or Bazaar script moving files from repository to web root). For my new setup, I'm considering installing everything on my local machine. I'm afraid that it will slow down workstation performance (LAMP + Eclipse), and that compatibility problems will kick-in. What would you recommend? Should I develop using two separate machines? On one? Do you have experience using one of above configurations in your work?

• Terminal, vim and ssh color problem

  - by xaph

  I'm using vim for my editor. I've problems about the colors of vim. The same colorscheme of vim gives different outputs in terminal, ssh session and screen. I learnt they've different colors(16, 88 or 256). I don't care of using 16 color or 256 color. Also the terminal emulator is not very important to me. My questions: 1- How do I use same vim colorscheme with same output on everywhere? 2- I want to write a color definition and use it every terminal(maybe with Xdefaults file). Is it possible?

• Trying to reinstalling .net framework 4 on windows server 2003 SP2

  - by LBR

  I had a problem with an application that was using .net framework 4. So I tried to fix the installation but it didn't solved. So I proceed to uninstall the framework and install it again. But then the problems started... the setup just wouldn't finish to download the framework. So i tried the full installer, and then it got stuck (freezes) at "installing client profile"... The server works well but the installation progress bar just stays at the same place (but the "wheel" keeps turning, like it was doing something, but stays like this for hours...) I tried the .net clean unistall software but the problem remains. I'm all out of ideas... I've searched the web but couldn't solve the problem with any solution I found... Any ideas on how to force the installation?

• Korea&rsquo;s Anti Abortion / Pro Life Movement

  - by Randy Walker

  The South Korean government is in dire straits.  The national birth rate continues to decline and as the population grows older, there aren’t enough children being born to support the country long term.  The social issues of post Korean War are coming back to haunt the empowered nation.  Being torn apart by the Korean War (nicknamed the forgotten war in America) and with a nation facing starvation, South Korea allowed hundreds of thousands of their children to be adopted abroad.  This has created a problem of epidemic proportions, essentially devaluing life in Korea and child rearing. In an effort to encourage birth rates, the government encouraged their workers to go home early and procreate by turning off the lights in buildings.  Something unknown to me, was the illegalization of abortion except in special cases. According to the this article, http://joongangdaily.joins.com it’s working.  Abortions are down and women are being encouraged to give birth.  However the flip side is illegal risky abortions are on the rise, with potential back alley abortions looming.  But with a nation facing it’s potential implosion, it has to continue it’s efforts to encourage mothers to give birth. Many of the issues that America has faced is in stark contrast to South Korea.  Abortion has been a generally accepted procedure for some time.  If you’ll recall, I mentioned South Korea devalued their children.  But the nation’s problems lie so much deeper.  Being an Asian nation, saving “face” is an important aspect of life.  And being an unwed mother disgraces the family.  Living as a single mother in South Korea is a difficult life.  Most married mothers stay at home to take care of the children.  Being a shunned single mother that has a hard time getting a job (because you are a single mother) and affording child care isn’t like life in America. If we in the states suddenly faced a birthrate crisis, what would the U.S. government do?

• What's wrong with this Open GL ES 2.0. Shader?

  - by Project Dumbo Dev

  I just can't understand this. The code works perfectly on the emulator(Which is supposed to give more problems than phones…), but when I try it on a LG-E610 it doesn't compile the vertex shader. This is my log error(Which contains the shader code as well): EDITED Shader: uniform mat4 u_Matrix; uniform int u_XSpritePos; uniform int u_YSpritePos; uniform float u_XDisplacement; uniform float u_YDisplacement; attribute vec4 a_Position; attribute vec2 a_TextureCoordinates; varying vec2 v_TextureCoordinates; void main(){ v_TextureCoordinates.x= (a_TextureCoordinates.x + u_XSpritePos) * u_XDisplacement; v_TextureCoordinates.y= (a_TextureCoordinates.y + u_YSpritePos) * u_YDisplacement; gl_Position = u_Matrix * a_Position; } Log reports this before loading/compiling shader: 11-05 18:46:25.579: D/memalloc(1649): /dev/pmem: Mapped buffer base:0x51984000 size:5570560 offset:4956160 fd:46 11-05 18:46:25.629: D/memalloc(1649): /dev/pmem: Mapped buffer base:0x5218d000 size:5836800 offset:5570560 fd:49 Maybe it has something to do with that men alloc? The phone is also giving a constant error while plugged: ERROR FBIOGET_ESDCHECKLOOP fail, from msm7627a.gralloc Edited: "InfoLog:" refers to glGetShaderInfoLog, and it's returning nothing. Since I removed the log in a previous edit I will just say i'm looking for feedback on compiling shaders. Solution + More questions: Ok, the problem seems to be that either ints are not working(generally speaking) or that you can't mix floats with ints. That brings to me the question, why on earth glGetShaderInfoLog is returning nothing? Shouldn't it tell me something is wrong on those lines? It surely does when I misspell something. I solved by turning everything into floats, but If someone can add some light into this, It would be appreciated. Thanks.

• How do I know when my on-board ethernet is dead? (Realtek 8112L LAN controller w/ AI NET2 )

  - by Usagi

  So I have an ASUS P7P55D-E Pro motherboard. It has an on-board Realtek 8112L LAN controller w/ AI NET2. I suspect that my LAN controller is dead but I don't really know for sure. This is what I know thus far: Everything was working, I have a triple booted system and ethernet was functional under Linux, Win7, and OSX. My ethernet is no longer functional under all three of the operating systems. I was experiencing random momentary internet outages before everything finally went dark. I don't know much about the AI NET BIOS tool but I believe it just checks for ethernet problems before you boot into an operating system. In any case, it doesn't find a connection upon boot. I've checked the connection on a couple of other machines and everything worked fine. I think I already know the answer to my question, but are there any other possible explanations, or is it dead?

• Can IP v4 and IP v6 share a single physical Ethernet?

  - by sleske

  I keep reading about the transition from IP v4 to IP v6, and the possible advantages and problems. One thing that keeps popping up is "dual-stack" networking, meaning (I believe) a host can speak both IPv4 and IPv6. I don't quite understand how this works, however. Can a host actually transmit using IPv4 and IPv6 at the same time over the same physical Ethernet (like e.g. HTTP and FTP can be used simultaneously)? Or is the physical network strictly IPv4 or IPv6, with the "other" protocol sent via tunneling?

• Is there a way to make IETab always open a site in Internet Explorer?

  - by reg

  Hello, IETab offers a setting that lets you define sites that should always be opened using IE's rendering engine. This is great and I use it all the time. There are a few sites, though, with which I encounter problems when I access them this way (needless to say that these have some IE-only features, otherwise I would simply use Firefox without IETab). So my question is: is there a way to make IETab (or any other extension that does the same thing) automatically open a specific list of sites in IE? To be clear: I want a way to specify a list of sites that will open an external IE process from Firefox, when clicking on those links or bookmarks from within Firefox.
