• How to make WinServer's AD work with Linux DNS/DHCP on VMware?

  - by Borald

  Hope you're fine. I got 2 virtual machines : Windows Server 2008 with Active Directory installed. Linux that works as a DNS and DHCP Server I need to make them work together, but I don't if this is going to be possible because VMWARE is sharing the NIC with other virtual machines and computer itself. I've assigned different IP static adresses to the servers. Is there a way for me to make these things get interconnected and test them on some virtual clients ? Any help will be much appreciated... (useful links,tutorials,..) Thanks in advance !

• How do I use an API?

  - by GRardB

  Background I have no idea how to use an API. I know that all APIs are different, but I've been doing research and I don't fully understand the documentation that comes along with them. There's a programming competition at my university in a month and a half that I want to compete in (revolved around APIs) but nobody on my team has ever used one. We're computer science majors, so we have experience programming, but we've just never been exposed to an API. I tried looking at Twitter's documentation, but I'm lost. Would anyone be able to give me some tips on how to get started? Maybe a very easy API with examples, or explaining essential things about common elements of different APIs? I don't need a full-blown tutorial on Stack Overflow; I just need to be pointed in the right direction. Update The programming languages that I'm most fluent in are C (simple text editor usually) and Java (Eclipse). In an attempt to be more specific with my question: I understand that APIs (and yes, external libraries are what I was referring to) are simply sets of functions. Question I guess what I'm trying to ask is how I would go about accessing those functions. Do I need to download specific files and include them in my programs, or do they need to be accessed remotely, etc.?

• print job doesn't go to print queue

  - by flatsguide

  I have two printers hooked up to my intel imac. I am having a printing error. It seems that whenever i try to print (a simple text doc) I am unable to get the print job to go to print queue with one of my printers. I have a HP c7280 and a HP c3100. I am able to get one working properly, but the other doesn't seem to allow it to go to the print queue. I have switched usb cables (with the printer that I know works) and both printers are recognized by the computer in the printer preferences pane. I've tried reseting the printer system in the printer setup utility.. reloaded the drivers from HP.. etc. If anyone has a suggestion or could point me to a little help i'd be VERY grateful Best Regards..

• Is there a software that can remap the keys for a speficic keyboard?

  - by Vilx-

  There are several keyboards attached to my computer. I'd like to remap the keys on ONE of them, but keep the rest as they were. Is there a software that does this? As for the "why" - I have this idea that I'd like to have a "multimedia keypad" which is separate from my main keyboard, but I could not find any online. So I think that I could take a typical USB numpad (they cost like 5$), and remap the keys on one of them. Add appropriate stickers, and I'm all seat, cheaply. I know that it's theoretically possible, but before I get my hands dirty and write my own software, I'd like to see if there's maybe an existing one out there. Oh, yes, I'm running Windows 7.

• Auto-connect Bluetooth headphones in Windows 7 64bit

  - by CptSkippy

  I have a pair of bluetooth headphones that I've successfully paired with my Windows 7 64bit machine and audio plays through them without a hitch. On the Device Stage under the properties of the headphones in troubleshooting it shows "last connected" as "currently connected" even if I power cycle the headphones or after a reboot of my computer. So the Windows bluetooth stack has no trouble finding them. The problem I have is that whenever the headphones reconnect to my pc they show up as disconnected in the Sound Settings and no sound is routed to them until I manually connect them. I have to go into Sound Settings, then from the Playback tab right click on the headphones and choose the Connect option. Is there a way to make the Sound Settings connect automatically whenever the headphones are available to Windows?

• Does the password get sent in the clear when connecting to Sql-Server?

  - by Scott Chamberlain

  I was asked this today and I honestly did not know the answer. If you connect using a connection string without sspi to a server is there any way a 3rd party can intercept on the wire the password used to log in? "Data Source=MyServer;Initial Catalog=MyDatabase;User Id=sa;Password=CanThisBeSniffed;" I am not asking about MiTM attacks just someone listing on the same computer or on the same hub on the network with wireshark or something similar running. I fired up wireshark myself and did not see it in plain text but it could be a simple obfuscation or proper encryption, I just wanted to know which.

• How do I interpolate air drag with a variable time step?

  - by Valentin Krummenacher

  So I have a little game which works with small steps, however those steps vary in time, so for example I sometimes have 10 Steps/second and then I have 20 Steps/second. This changes automatically depending on how many steps the user's computer can take. To avoid inaccurate positioning of the game's player object I use y=v0*dt+g*dt^2/2 to determine my objects y-position, where dt is the time since the last step, v0 is the velocity of my object in the beginning of my step and g is the gravity. To calculate the velocity in the end of a step I use v=v0+g*dt what also gives me correct results, independent of whether I use 2 steps with a dt of for example 20ms or one step with a dt of 40ms. Now I would like to introduce air drag. For simplicity's sake I use a=k*v^2 where a is the air drag's acceleration (I am aware that it would usually result in a force, but since I assume 1kg for my object's mass the force is the same as the resulting acceleration), k is a constant (in this case I'm using 0.001) and v is the speed. Now in an infinitely small time interval a is k multiplied by the velocity in this small time interval powered by 2. The problem is that v in the next time interval would depend on the drag of the last which again depends on the v of the last interval and so on... In other words: If I use a=k*v^2 I get different results for my position/velocity when I use 2 steps of 20ms than when I use one step of 40ms. I used to have this problem for my position too, but adding +g*dt^2/2 to the formula for my position fixed the problem since it takes into account that the position depends on the velocity which changes slightly in every infinitely small time interval. Does something like that exist for air drag too? And no, I dont mean anything like Adding air drag to a golf ball trajectory equation or similar, for that kind of method only gives correct results when all my steps are the same. (I hope you can understand my intermediate english, it's not my main language so I would like to say sorry for all the silly mistakes I might have made in my question)

• Why is my disk full?

  - by Agmenor

  I installed Ubuntu 12.04 by doing a fresh install where there was previously Ubuntu 11.10. My computer warns me now that my disk is nearly full. After having run apt-get purge, run apt-get autoremove and emptied the Trash can, I still have this problem as shown by this screenshot of Gparted: The disk /dev/sda7 is indeed full. I ran the Disk Usage Analyzer (Baobab) and I am still not sure of what is happening: One of my hypothesis is that when installing Ubuntu 12.04, I didn't configure my disks well and the disk /dev/sda6 is not mounted well as /home. Is this the reason indeed? What should I do to verify this and then to get the things fixed? Here are a few additional details to answer the questions I received (thank you everybody): My home directory is not encrypted. The Backup utility (Déjà Dup) is not set for automatic backups. (I do it myself and manually.) After I mount /dev/sda6, the command df -h gives Filesystem Size Used Avail Use% Mounted on /dev/sda7 244G 221G 12G 96% / udev 3,9G 4,0K 3,9G 1% /dev tmpfs 1,6G 904K 1,6G 1% /run none 5,0M 0 5,0M 0% /run/lock none 3,9G 164K 3,9G 1% /run/shm /dev/sda6 653G 189G 433G 31% /media/8ec2fa69-039b-4c52-ab1b-034d785132a1 (sorry but formatting this into code does not work, for an unknown reason) Thanks to izx's post, I realized /dev/sda6 was not even mounted before. It contains all the documents I used to have when I was running Ubuntu 11.10.

• Remote Access using Windows 7 Home Premium

  - by klelky

  I'm hoping to try and do some trans-atlantic tech support for my in-laws. Both my machine and theirs are running Windows 7 Home Premium. I read in this HowToGeek article that the Home editions of Windows 7 and Vista don't support remote access. What's the most straightforward way for me to access their machine - bearing in mind that they are a retired couple and this is their first computer and therefore anything that needs to happen at their end needs to be super simple. Free would be prefered but if there is a good paid for solution I'd consider it.

• Can't install newer NVIDIA display driver on Windows 7

  - by Mr.X

  I'm using Windows 7, and the latest version of NVIDIA display driver I can install on my computer is 275.33 (or 266.58, I can't decide now, see below). When installing newer version of the driver (e.g. 275.50 and 280.26), the installer always fails at "Installing NVIDIA Control Panel", then Windows 7 reverts to 275.33 (the newest stock version?). I tried to find installation logs but couldn't find it. I tried to completely delete (in fact I renamed) c:\progra~1\nvidia~1 folder but still couldn't install. How to resolve this problem? Any help is appreciated.

• Can't login to Unity 3d after enabling Xinerama for a short moment

  - by Amir Adar

  Today I connected a second monitor to my computer. I set it up using nVidia's control panel, and all was working quite well, so I figured it won't be a problem to try Xinerama, just to see the difference between that and twinview. After enabling Xinerama and restarting the X session, I saw that I was logged into a Unity 2d session. I thought it was a problem with Xinerama, so I switched back to twinview, but it still logged me into Unity 2d. I tried disconnecting the second monitor, no luck: still Unity 2d. I tried changing GPU drivers and installing drivers from a separate ppa, and still I was logged into Unity 2d. Up until this point, I didn't have any problem logging into Unity 3d. It only happened after I tried using Xinerama. I should note that I was doing all this while updates were going on in the background, so it could be something related to that, though I can't imagine what (I tried booting with another kernel, but no luck). So what exactly happened? Did changing the mode to Xinerama triggered some other changes that I'm not aware of? Did these updates cause a certain malfunction in the driver? Is it something else?

  My 4 roomates and I have a problem: One of my roomies is downloading torrents all the time. When somebody need make a call or doing something like you tube or a quiz using the internet conection. The internet is very slow.... I can not create a network using a computer as a proxy. I just need a good router (and in the budget no more than $50).. I just want to split a 16MB connection into a separated 4 x 4 mb (theoretically)..

• First request too slow even if I have a load balancer in the back

  - by adrian7

  I have an Apache 2 on Centos + bind with a wordpress website on it (e.g example.com). I have also set up, on another server in a different contry a load balancer (varnish:80 + nginx 127.0.0.1:8080) for it - which task is to server all static content under /wp-content/. Using Simple DNS editor I added an A entry to cdn.example.com pointing to the server's IP. So no extra work from a 2nd dns server. Then using htaccess I redirect all requests to jpg|gif|css|js files to cdn.example.com. That works and all files are saved on the "cdn" server and served right away. My problem is that for the first time I enter on example.com (e.g after restarting the computer or closing the browser) the load time is 1 up to 3 seconds, while any subsequent page loads take only 300 to 600 miliseconds. I know it might be a DNS issue, but I have done a cache check on several websites and cdn.example.com indicates the right IP. Do you have any ideas where I should dig to solve this first-time slowness?

• Linux Mint on VirtualBox has no internet connection

  - by Martin

  Physical machine: Mac Mini running OSX 10.7.5 Virtual machine: Linux Mint 15 Cinnamon 64-bit Using VirtualBox. I am trying to make the linux connect to the internet. For some reason I can access the host computer with 192.168.2.100. Its set up to show me a web-page that says "It works". This I can see from the linux. But I cannot reach anything on the internet. Either FireFox says "Unable to connect" or when I run nslookup google.com I get connection timed out; no servers could be reached. My setting on VirtualBox under the Network tab are: Bridge Adapter vnic0 promiscouos Mode:Allow All`. If it makes a difference, the host has a WiFi connection to the home router. What have I missed?

• Looking for internet traffic manager software for Windows 7

  - by Semyon Perepelitsa

  I have 128 KB/s (1 Mbit/s) internet connection. Not quite fast for downloading big files, but it is okay for internet browsing. When I start big file dowload, I cannot surf the web normally: pages appears slowly, especially pictures there. Therefore I pause downloading, but I'm regularly spending much time on reading articles or leaving the computer alone, when I can allow the file being dowloaded. Is there any software that can automize the process of pausing and resuming download or simply automatically regulate internet speed for each application using Internet? I download files using different software and protocols (Download Master for http, ftp; uTorrent for torrents; many other programs for updating themselves), so I don't want to be tied to particular program for downloading.

• I'd like to archive files from Ubuntu to Windows between two computers on a shared home network

  - by Wabbitseason

  I have an old laptop running Ubuntu 9.10 which I use as a LAMP environment for web development, and I have a comfortable, powerful desktop computer with Windows 7 installed on it. These two are connected to a home router so both can access the internet. I have been able to set up Samba so I can mount my Apache home directory so it is accessible from Windows and is mapped as a network drive. What I'd like to do is access some Windows folders from Linux so I could automatically create backups (with cron scripts) of my work to physically different locations on the Windows box. Perhaps at a later time I'd set up a local Subversion repository but I'd love to keep backups of that on the Windows drives too. Using Ubuntu's Places/Network menu I can see my desktop but I'm unable to log in to that despite having created the corrent username and password on Windows. All I can get is the following error message: "Unable to mount location. Failed to retrieve share list from server." What could be misconfigurated?

• No write access on Windows 2008 workgroup share

  Hi All, I'm trying to access network shares on my new Windows 2008 server (workgroup) using my server's local admin account. I can read files but not modify them. Permissions (sharing + file system) say: Users = Read only. Admins = Full Control. Even though I connect using my admin account (net use x: \\server\share /user:server\me), I can't write. OTOH, I have another share on the same computer where users have Read AND Write. I can write into that one. What's the problem? Does it have to do with UAC? TIA for your help.

• Show Slave Status not working from console, nor client.

  - by Mr. Leinad

  Hello, I have a somewhat strange case. Whenever one of my coworkers executes this line: show slave status; from their MySQL clients, it works smoothly. But if I do that, it says: ERROR 1227 (42000): Access denied; you need the SUPER,REPLICATION CLIENT privilege for this operation We are all going against the same database, and if I check privileges I can see: GRANT ALL PRIVILEGES ON . TO 'usermysql'@'%' IDENTIFIED BY PASSWORD 'password' There's something wrong with my computer.. but I can't pinpoint where it is.. Thanks EDIT: It's kinda bizarre.. it goes through a VPN remotely. But if I change the internet connection, then it works.. If the previous internet connection is restored, it doesn't.. Could we classify this among the great mysteries of the world? Or someone has an idea?

• does any sync software find files that have moved paths within a folder?

  - by kpierce8

  Say I have a pictures folder which I reorganized on one computer. I'd like to use that directory as the base and compare it with another version on a backup drive. Will any sync/compare program find that a file in one folder has moved locations within a compare folder. For instance say I reorganized my pictures from trips into folders by year with the trips folders inside each year folder. If I use a regular compare utility I wind up with two copies of everything that's moved in different locations.
