  • Mac OS X change IP configuration automatically by location (by Wifi network)?

    - by Seppo Sade
    Can Mac OS X be setup to automatically configure its Airport interface with a static IP address when connected to a Wifi network with a certain name, and on all other Wifi networks use DHCP? Currently I'm using the "Locations" feature of the "Network" section in System Preferences to manually switch between two IP address setups. I have a "my static IP" setup, and a default "DHCP" setup. However this requires entering System Preferences to change the Location drop-down each time when switching locations. Can this be automated? Preferably this would be done without third-party software.

  • Hylafax with serial over IP modem

    - by zero_r
    I'm looking into virtualizing a Hylafax server which currently runs on a dedicated hardware running CentOS with a Divalogic card. The main issue obviously is, how to connect the modem to the VM. There are serial over IP devices available at digi.com. Maybe there are others? Regarding digi.com devices, as far as I understood one can install the RealPort software and then have a /dev/ttySx device presented to the Linux server. This device then can be used as serial connection to the modem. Does someone have such a configuration in place? Or does someone have another idea to virtualize a Hylafax server (outbound faxes only). Thank you in advance

  • What does the term 'overinstallation' mean?

    - by Kent Pawar
    I came across this term here: "11882875 -- Essbase Server does not start after an overinstallation." I know that a clean install is a software installation in which any previous version is removed. Googling 'overinstallation' turned up nothing, and I don't like to just assume it simply means 're-install'. UPDATE: So my understanding now is - the term "re-install" can be a bit ambiguous as it could either signify an installation after an uninstallation or otherwise. On the other hand the term "over-installation" specifically talks about installing something over an existing installation, that involved no uninstallations.

  • Preventing apps to access info from wifi device?

    - by heaosax
    Browsers like Chrome and Firefox can use my wifi device to get information about the surrounded APs and pin point my physical location using Google Location Services, I know these browser always ask for permissions to do this, and that these features can also be "turned off". But I was wondering if there's a better way to prevent ANY application to access this information from my wifi device. I don't like anyone on the internet knowing where I live, and I am worried some software could do the same as these browsers but without asking for permissions. I am using Ubuntu 10.04.

  • Is this a good implementation of a loop in Prolog?

    - by Carles Araguz
    First of all, let me tell you that this happens to be the first time I ask something here, so if it's not the right place to do so, please forgive me. I'm developing a rather complex software that has a Prolog core implementing a FSM. Since I don't want it to stop (ever), I'm trying to write a good loop-like predicate that would work using Prolog's recursion. After a few unsuccessful tries (mainly because of stack problems) I ended up having something similar to this: /* Finite State Transition Network */ transition(st0,evnt0,st1). transition(st1,evnt1,st2). transition(st2,evnt2,st0). fsm_state(state(st0),system(Energy,ActivePayloads),[]) :- /* ... */ transition(st0,evnt0,NextState), !, fsm_state(state(NextState),system(Energy,ActivePayloads),[]). fsm_state(state(st1),system(Energy,ActivePayloads),[]) :- /* ... */ transition(st1,evnt1,NextState), !, fsm_state(state(NextState),system(Energy,ActivePayloads),[0,1,2]). fsm_state(state(st2),system(Energy,ActivePayloads),[P|Params]) :- /* ... */ transition(st2,evnt2,NextState), !, fsm_state(state(NextState),system(Energy,ActivePayloads),[]). start :- Sys = system(10,[]), fsm_state(state(s0),Sys,[]). Is this a good approach?

  • 'Unlimited' free trial of Windows Server 2008 by deleting and reinstalling VM? [closed]

    - by MrVimes
    I am using Virtual Machine software (VirtualBox) to learn Windows Server 2008 R2 Network Infrastructure (70-642). Trouble is - I'm learning at an extremely slow pace and so the trial periods of my virtual machines are close to running out. If I delete the VMs then install WS2008R2 from scratch on new VMs is that violating the acceptable use policy of Microsoft? I am aware that I can extend the trial, but it seems I can only do that by 10 days at a time. Also I think having to re-install from scratch is a good way to reinforce the knowledge.

  • Linux virtual disk stripping or multi-path samba share?

    - by wachpwnski
    I am trying to build a file storage box for media. It needs to span two or more directories or partitions as one share. There are a few solutions but reasons why I want to avoid them, among these are: Using LVM2 for stripping. I don't really have the resources to back up everything on the volumes incase one HDD goes south. I would end up loosing everything. Maybe there is a better option for this to prevent data loss with hot swappable drives or some kind of raid. Using symbolic links in the share. This will get tedious every time a new sub-directory is added. Is there some kind of software raid I can use to merge two directories virtually? I am aware of the issue where /dev/hda1/media/file.1 and /dev/hdb1/media/file.1 both exist. But I'm sure there are some creative solutions for this.

  • Mouse selects everything on its own

    - by meneer
    I have a strange problem that my mouse keeps selecting everything I point to. For example, if I open Rhythmbox, then at the top of the screen there is a text which says which song is playing. If I move my mouse over this text, then it will select this text; but I am not clicking. This behaviour does not happen in all programs. For example in Firefox I have no problem at all. Maybe it is Gtk related? Nautilus also behaves strangely; I cannot open files by clicking on them, I have to select and make a box around the file and then press enter to open it. If I click, then nothing happens. Similar problems also happen with other Gtk software. I think the problem might be related to touchscreen issues (I have a touchscreen). I run Gnome 3 on Ubuntu 12.04. I have a HP touchsmart 610 desktop computer. Any help is greatly appreciated. UPDATE: I just did a fresh reinstall, and I am 90% certain that it is related to the touchscreen drivers. Here is what happens when I reinstall. At first boot, so exactly after install, everything works fine, except the touchscreen: The touchscreen does not respond. I update ubuntu, because I installed from an old CD (CD with ub. 12.04). Then on next reboot I have touchscreen working , but the working touchscreen comes together with the mouse selecting everything on its own. SECOND QUESTION: Would anybody know how I could figure out what those touchscreen drivers are (so that I can disable them) ?

  • Windows backups to VM Esxi

    - by Martyn
    I'm very new to ESXi, so apologies if this is a silly question. I have ESXi 5.1 running running on HP Proliant Microserver with internal LUNs RAIDed with HP P410 Smart Array card. I have 2 Windows Server 2012 VMs running as Domain controllers. These are being backed-up up with GhettoVCB to a dedicated datastore hosted on LUNs on a eSata external device. I have several Windows 8 & 7 PC's connected to this domain. I want to back up these Windows PCs, via the built in backup software, ideally to the external eSata device as well. What do I need to do to have the Windows PC's see the datastore? I assume I could create a VM for FreeNas or something, or share out the datastore via one of the Windows Server 2012 VMs. Both those options seem a little bit of an over kill?

  • good books about server architecture?

    - by ajsie
    when the traffic for a website grows i dont think one apache server in a vps is the way to go. i would like to know more about how i then should set up the server side architecture. im not that much into hardware stuff (what kind of cables to use, different cpu architectures etc), but interested in the software architecture: what servers (apache, nginx, squid, varnish etc) to use and how they interact with each other one server in one machine? how many mysql servers. how many apache, nginx servers and so on. how the "machine court" looks like. are there any good books about this area?

  • how can I get rid of duplicate administrators on 2 macbook pro's

    - by BCITY
    I got a new MacBook Pro (insurance payout) and passed my old one (previous generation MacBookPro 2008) on to a staff member whose MacBook Pro died. I used carbon copy to move my data to the new laptop but couldn't do the same with her move as the older Macbook wouldn't allow it as it was on an old OS. Ended up just migrating her software onto my old MBP. Now however, they both have the same admin identities and her computer is synching with my mobile me account. Can I change the administrator identity and save all her applications? I am hoping that I don't have to wipe and reinstall everything to change her computers identity.

  • How to make my display Grayscale?

    - by Oldarney
    I want to reduce the saturation of my laptop monitor to the point that it is almost grayscale. That's the goal. Intel and Asus don't have an answer. Asus Splendid and the intel graphics control panel can increase the saturation, but not lower it. I would prefer a software solution, although I DIY'ed a vga grayscale adapter for my desktop. I have an Asus UL30A with an Intel GMA 4500MHD. I know that the latest ATI cards, windotosh's and high end nvidia cards all support control panel desaturation. Why? black and white makes me 3 times more productive.

    At work there are about 40 PCs. I want to block all the websites and only allow a few Domains/Websites for operators. A few operators can access anything. I want something quick and easy so I can filter the Block/Allow websites for all computers from one main computer, like a server or something. Windows Vista Home and Windows 7 Home are installed on the PCs. Is there any software can do this? PS: Please don't answer about Microsoft Windows Server OS..

  • Is there a way to undo deletion of registry keys while the machine is still running?

    - by Oliver Giesen
    [ also posted from a programmer's POV at http://stackoverflow.com/questions/3299230 ] I messed up big time and deleted a large portion of my registry during a programming experiment: As a result most of the contents of HKEY_CURRENT_USER\Software\ are gone. I haven't logged off or shutdown since this happened. The applications that were already running seem to be coping fine so far but I suspect that after the next reboot there won't be much happiness left... Also, System Restore tells me there are no restore points even though I'm pretty sure there should have been. Could this be another symptom of the purged registry? I wouldn't have expected this information to be stored under HKCU, though... Does anybody know of a technique or utility that can possibly restore some or all of the deleted entries? I'm on Windows 7 Enterprise 32bit. I'm not really holding my breath but you can always hope, can't you?

  • Should I be concerned that I can't program very fast without Google? [closed]

    - by seth
    Possible Duplicate: Google is good or bad for programmer? I'm currently in college to be a software engineer, and one of the main principles taught to us is how to learn for ourselves, and how to search the web when we have a doubt. This leads to a proactive attitude - when I need something, I go get it. Recently, I started wondering how much development would I be able to do without internet access and the answer bugged me quite a bit. I know the concept of the languages and how to use them, but I was amazed by how "slow" things were without having the Google to help in the development. Most of the problems I have are related to specific syntax. For example, reading and writing to a file in Java. I have done this about a dozen times in my life, yet every time I need to do it, I end up googling "read file java" and refreshing my memory. I completely understand the code and fully understand what it does, but I am sure that without Google it would take me a few tries to get the code correct. Is this normal? Should I be worried and try to change something in my programming behaviour?

  • Searching Objects on SonicWALL (NSA 2600, SonicOS 6.1)

    - by Justin Scott
    Ok, this may sound like a dumb question, but does the SonicOS web interface not have a search option for object definitions? One of my clients recently decided to replace their Astaro Security Gateways with SonicWALL firewalls. These sit in front of a small data center full of servers and we have several hundred custom service and address definitions that need to be ported. The SonicOS interface provides a basic list for service and address definitions but no search option to be found. To make it worse, there is no option to list them all on one page (they're paginated 50 at a time) so I can't use the text search on the web browser either. The Astaro units have a nice search option on their definitions so perhaps I just got spoiled by their software. Am I missing something or is there some way to search for an object without paging through the list and finding an entry manually?

  • What does it mean for a computer to be an "IBM Compatible PC"?

    - by Jon
    A couple questions about this: 1) Is this term even relevant any more? 2) Does this mean anything from a developer's stand point? It is not exactly clear to me if this is a BIOS, architecture, bus or a combination. A piece of software I'm working on expects to see a "Description" of the system and currently windows machines report "AT/AT Compatible". Having been tasked to port this to Mac, I really don't know what a proper "Description" would be - this will most likely be omitted but I was wondering if anyone could provide some insight on the modern usage of this term.

  • Security considerations when giving access to SQL Server db for a web application

    - by rem
    I need to expose our SQL Server 2008 database for an access from a asp.net web application. This is a new task for me, so I would like to know what basic security requirements are there for configuring software and hardware components of web server and DB Server. Is it OK to have both Web Server (Windows Server 2008) with IIS holding ASP.NET application and SQL Server 2008 on the same machine? Should I have to install additional firewall, like Forefront TMG? Should it be on separate computer? In case a web application is hosted on an external web hosting privider server and SQL Server DB on a our internal server what are "pro's" and "con's" of such configuration?

  • why can't i delete this file on my pc

    - by ooo
    i am trying to install some software and it requires removing the following file: cd %SYSTEMROOT%\assembly\GAC rename Microsoft.Office.Interop.Outlook Microsoft.Office.Interop.Outlook.Old the problem is when i do the rename it looks like its successful but it doesn't seem to actually delete Microsoft.Office.Interop.Outlook i tried to explicitally do: del Microsoft.Office.Interop.Outlook and again it looks like it works but then when i do a "dir" i still see that file. Do you have any suggestions on why this wouldn't allow me to delete this file. I have outlook closed when i am doing this so i wouldn't think outlook is locking the file.

  • Backup Mongodb on EC2 through EBS snapshots - timing issue

    - by DmitrySemenov
    I'm following this guidance http://docs.mongodb.org/ecosystem/tutorial/backup-and-restore-mongodb-on-amazon-ec2/ I have 4 EBS 1000 IOPS volumes assigned to instance These 4 volumes through MDADM assembled into software RAID10 array. I want to do backups through EBS Snapshots as explained in the article above Question: Mongodb says - that I need to mongo shelldb.runCommand({fsync:1,lock:1}); -- this will lock the db for writing ....run snapshot creation... mongo shell db.$cmd.sys.unlock.findOne(); -- this will unlock the db for writing so do I need to unlock the DB for writing after I issued the comand ec2-create-snapshot or after it's finished and the actual snapshot is created thanks, Dmitry

  • Will installing an Ultra ATA cable backwards affect performance?

    - by GMMan
    I've recently purchased a hard drive upgrade for my Xbox 320GB WD Caviar Blue WD3200AAJB and StarTech.com Ultra ATA/66/100/133 cable IDE66 yes I'm crazy When it came to installing the cable, it was too short (my fault), and there wasn't enough space between the master and slave ends to reach both the DVD drive and the hard drive. The only thing I could do was install the cable backwards and twisting it quite a bit to make it fit. The upgrade works, but reading the manual for the hard drive I replaced (10GB Seagate U Series 5), apparently there is a specific way you have to connect the cable. I don't have that option, so the question comes down to, will my drive performance be at Ultra ATA levels, or is it still performing at original ATA speeds? Is there any way I can test this (benchmarking software for Xbox)?

  • Pull/push student assignment files from computer lab computers (Windows 7)

    - by mkstreet
    I have a computer lab with about 35 PC's all running Windows 7. The students do their work and save it on the D-drive in a particular folder such as a folder with the same name as the computer's name (e.g. LABPC001). I'd like a centralized way to pull all these folders in to the teacher's computer in the lab to check the assignments. It would be best if this didn't involve using an external website (e.g. Dropbox). I would also like to be able to distribute (send) files to the students in these same folders. I've seen software applications that do this but they cost about US$1000 which is far beyond our means. Suggestions for free, or almost free, best ways to set this up?

  • Netbook recomendations for a developer

    - by Joe
    I am thinking about getting a netbook for a secondary laptop. Ideally it would mainly be used for surfing/email/travel, but I would like it to be good enough to be able to run Visual Studio for when I am at conferences and the like. I as thinking it would be nice to be able to put a 16-32GB SSD in it, as well as 2GB of memory. Do you have any recomendations? Will a netbook even suffice, or should I upgrade to a small-form laptop? Edit: I don't need to be able to build software on it. It would just be nice to occasionally be able to try out new tools, APIs, or what have you without getting frustrated due to limited computing power.
