  • How can email possibly be routed to the right place with no to: address?

    - by agent154
    I'm no novice on networking technology, but one thing I don't really know much about in detail is email and headers. How does email work SPECIFICALLY? I'm getting spam in my hotmail inbox when I've made painful attempts to not give out my actual email. I use my own domain name to forward email to my inbox using several aliases. Yet now I'm getting spam with no address in the to: line, or also "undisclosed recipients". Looking at the headers is of no help whatsoever. So from a technical standpoint, I have to wonder... if I send an email to a certain address in my personal domain and it gets forwarded to my hotmail account, how does hotmail know what inbox to dump the message in if that address is not listed in the headers?

  • Upscaling audio from 2.1 to 5.1 in Windows 7

    - by Darth Android
    I'm currently using the onboard sound on my Asus P6T6 WS Revolution motherboard (SoundMAX Integrated Digital Audio) and was wondering if there was any way to make either windows or the audio drivers upscale 2-channel audio to 5-channel audio (basic duplication would suffice)? I was using a creative sound card but got fed up with the memory leaks and poor sound quality.

  • Relationship between RAM & processor speed

    - by deostroll
    RAM is just used for temporary storage. But since this storage is in the cpu memory (RAM) it is fast. Programs can easily read/write values into it. I've noticed more the RAM less time it takes for the application to load/execute. But doesn't this actually depend of the processor speed (MHz or GHz values). I am wondering what is the science/relationship between processor speed and RAM.

  • Shut down windows service based on load

    - by JP
    Hello, I was wondering if there are any free / open source solutions that will start and stop a windows service based on load? I have some pubsub subscriber services that do background work which is not critical. Ideally i would like tot be able to automate things so that these services could start if memory/cpu/disk i/o was under a certain threshold and stop gracefully if that threshold was met. Do you know of any solutions? Thanks JP

  • Windows 8 Fails to resume from sleep

    - by AnonymousAppDev
    I have this weird issue. When I put the computer to sleep by pressing the power button, or using the sleep option in Charms, I can wake it up normally. However, if I close the lid, and later reopen it, all the fans come on, but nothing appears on the screen. I didn't have this issue using Windows 7. Here are my system specs: HP G60-235DX Notebook PC Intel Pentium Dual Core T4200 at 2.00Ghz 3 GBS of RAM Intel Graphics Media Accelerator 4500MHD with 1309MB of video memory Windows 8 Pro 64 bit

  • How can user change the jre parameter values after the exe is generated in Launch4j?

    - by Wing C. Chen
    Is it possible to change the jre parameter values after the exe file is generated through Launch4j? The ideal scenario is like this: The default parameter values are applied when the program is started. However, when the user wants to change some jre parameter values, he goes to a .ini file, MyProgram.ini for example, changes the values there, and the new values will be applied next time the program is started. I think eclipse uses the same way for its memory and some other parameter settings.

  • Which EC2 instance best for Chef server?

    - by hakunin
    I want to setup chef server as cheaply as possible, while leaving it enough room to run without crashing. The only article I found on the subject warned that RabbitMQ would crash on a micro instance due to insufficient memory. The question is: what's the cheapest EC2 instance that can run chef server reliably, considering that I don't use CouchDB or RabbitMQ for anything else in my app, so would probably have to set them up exclusively for chef server on that same instance.

  • Auto-rebooting blackberry [closed]

    - by Mr Fooz
    My BlackBerry Bold (9000) auto-reboots approximately daily, generally while I am listening to podcasts that have been saved to my add-in memory card. Neither the built-in card nor my add-in card are full. An OS update had no effect. I am using the default media player. Has anyone else experienced this or does anyone know how to fix this problem?

  • Debian tuning for increasing read/write buffer.

    - by Claudiu
    Is there a way to modify Debian settings so the memory could be used more for disk read/write caching ? I am already using RAID 0 but thats not enough for multiple users, and the disk is almost struggled. Torrents use the disk very much and rTorrent doesn't have cache settings.

  • Avoid read-write access to bad sectors on HDD to continue working on the HDD

    - by goldenmean
    I have a HP Pavilion dv6446 notebook. It had Windows Vista Home premium. After 4.5+ years of usage, just recently it started malfunctioning. While working fine, its screen goes white or sometimes some thin black lines horizontally. Laptop freezes. Hard reboot works. Again it works for some 2 hrs or so, same error. To diagnose I did run the Memory and Hard disk check which is present in the Bios Setup. Memory test passed. Hard disk test returned an error saying something like - "Replace the hard disk". Bad.. Some sectors or platters have gone bad on the disk. (I confirmed this later by further tests mentioned below) Then I tried installing a Ubuntu 11.10. It listed 3 partitions /dev/sda1, sda2, sda2. It again gave error and could not install grub loader on /dev/sda1. Bad sectors. Then redid the Ubuntu installation, this time asked to to install the Ubuntu on /dev/sda3. and kept /dev/sda1 for /home. Installed fine, and works fine as well. Due to unavailability of WiFi/ Ethernet driver for that adapters under Ubuntu( at least I could not configure them and get the networking working at all), I decided to go back to reinstall windows Vista. It did install fine. I did not have to format one data partition which has my data. I just formatted one partition which installed Windows So in effect HDD has not undergone a full format here. Worked ok for 1 day. But same white screen and freeze happened. Looks like while it is in use, it accesses the bad sectors for storing some data and that's when it bombs. I am inclined to think HDD has not failed fully or crashed but has developed bad sectors. Else if it was a HDD crash, it would have refused to boot at all let alone install on it. Questions: Is there any HDD test check under windows or any such tools windows/linux based ewhere which can identify the bad sectors of the HDD and 'lock/isolate' them from further read-write access of any kind. If not what are my options, if any to salvage this laptop HDD without replacing it. EDIT: Would the Disk Error checking tool under windows help in any way?

  • Command line import of database using latin1 encoding

    - by chrisjlee
    I'm using a particular cloud hosting solution (one which i won't name) and they don't provide ssh access so i'm at a whim on how the database is dumped. I downloaded the dump which is packed into a tar.gz file. I discover that this file utilizes latin1 encoding. Which i don't get to specify the encoding for the host i'm using because i don't have SSH access or DB access. I try to import it via command line for my local development environment (mysql -uroot foodb < file.db) like i usually do with other databases but am having problems. Is it possible to import a database via command line by specifying which encoding (preferably latin1) before importing it? Or do i have to convert it to UTF8?

  • How could I let Skydrive desktop sync to MicroSD in Windows 8 tablet?

    - by peSHIr
    I have a Samsung Slate 7 tablet with (now) Windows 8 on it. This machine has a 64 Gb SSD and I have a 64 Gb MicroSD card in it. I also have a Skydrive on my main Microsoft ID that contains about 45 Gb of content. With Windows and some development stuff installed, my Skydrive will not fit on the main drive of the tablet. (Besides, my idea was to keep data on the memory card anyway, to make it easier to repave the machine without data loss if need be.) My problem should now be clear: I want to install the Skydrive desktop app to sync my Skydrive to the MicroSD card. This is not possible, as Skydrive does not allow syncing files to removable drives. I have tried a number of things already, but none of them worked: Use the mklink command line tool to create a directory link/junction from a folder name on SSD to a folder on the MicroSD and then try to install Skydrive sync to the SSD link folder. Skydrive however still recognizes this as something it does not want to sync onto. The various different filter drivers mentioned on Agnipulse (including the Hitachi one) that should make windows see some or all of the removable drives in the system as fixed drives do not seem work on (64-bit) Windows 8: they either can't be installed, do nothing and/or cause Windows 8 to go into Automatic Repair mode when rebooting. The Lexar BootIt app seems to be meant to flip the relevant bit in the on-board drive controller of supported USB pen drives, but I tried it anyway. Of course it did nothing to how the MicroSD card was seen. I have now run out of ideas, it seems, and I was wondering if anyone here has a solution to let Windows 8 see the MicroSD memory card in my tablet as a fixed drive instead of removable drive, or some other way of getting the Skydrive desktop to sync my Skydrive data to that MicroSD card. And to be complete: this is not a duplicate question of this or this as those ask about getting USB drives multiple partitions to work on Windows XP. This question is specific about getting desktop Skydrive to sync to MicroSD card in Windows 8, which seems to be a question I have not seen on superuser so far.

  • Puppet: how to use data from a MySQL table in Puppet 3.0 templates?

    - by Luke404
    I have some data whose source-of-truth is in a MySQL database, size is expected to max out at the some-thousands-rows range (in a worst-case scenario) and I'd like to use puppet to configure files on some servers with that data (mostly iterating through those rows in a template). I'm currently using Puppet 3.0.x, and I cannot change the fact that MySQL will be the authoritative source for that data. Please note, data comes from external sources and not from puppet or from the managed nodes. What possible approaches are there? Which one would you recommend? Would External Node Classifiers be useful here? My "last resort" would be regularly dumping the table to a YAML file and reading that through Hiera to a Puppet template, or to directly dump the table in one or more pre-formatted text file(s) ready to be copied to the nodes. There is an unanswered question on SF about system users but the fundamental issue is probably similar to mine - he's trying to get data out of MySQL.

  • Windows 7 Computer Maintenance - Restore removed Desktop Shortcuts

    - by HaydnWVN
    I'm aware about the inbuilt nightmate 'tool' of Microsofts which is making every network administrators job a nightmare (if left turned on). In short it'll happily delete every desktop shortcut to a network resource. We have it disabled by default. My question is related to recovering these shortcuts, Windows doesn't seem to dump them into the Recycle Bin and although you can 'restore previous versions' of the Desktop folder, you are unable to do it with the user logged in... Rather a problem if you only have the 1 user account. We have a user who (although the 'Computer Maintenance' tool is turned off) had it come up in 'Action Centre' and chose to run it. I've been unable to reproduce it, but the tool has certainly run (and removed 24 shortcuts from her desktop) although it is still saying 'Windows is not checking your system for maintenance problems'. ?! Very fustrating! Any ideas if these shortcuts are backed up/moved elsewhere so i can easily find and restore them?
