  • Is it possible to live-boot VirtualBox from a USB flash drive?

    - by bw.
    To clarify, I'm not asking if you can boot from USB from within VirtualBox. I would like to make a portable version of Windows 7 that I can run from a USB drive on any machine. I'm putting a distro of Linux on my laptop, but I manage a Windows domain at work so I'd like an easier management solution than trying to use Linux tools to interface with a Windows DC(as RDP to a DC is not always an option). The reason I'm inquiring about VirtualBox... I plan on carrying this portable installation with me and using it on multiple machines, so I would like to avoid driver conflicts (which I imagine would happen if I only installed Windows on a flash drive). Basically, I need a way to boot an installation of Windows 7 from USB that still allows me to install/remove/update programs as if it were installed on a standard hard drive, and not freak out over different hardware configurations. Please help, superusers!

  • Is it possible to connect these machines with ssh tunnels or another mechanism?

    - by frankc
    I am physically on a machine that is behind a firewall and cannot be ssh'd into. Let's call that PC. PC can connect out to two machines, one on AWS and one that is part of a vpn connection, call them A and V, respectively. A and V cannot talk to each other directly. I need to frequently move files between A and V and have been doing this by scp'ing to PC and then scp'ing from pc. Is there a better way to do this? A and V are linux but PC has cygwin.

  • Is it possible to really delete a Facebook chat message or the whole chat?

    - by Forza
    Ok, so a few months ago me and a friend send a whole bunch of smileys to each other in Facebook chat just for fun. I wish I had known at that time how stupid that was. Even until today, every time I open the chat with that contact, the Facebook tab totally locks up when I try to load that chat. It will load eventually after five minutes or so, but it becomes very inconvenient at times. On Facebook Messenger for Android, there's no problem and the chat works fine. I'd like to know if there's any way to completely delete a Facebook chat (not archive them) and start over so it won't load the smileys anymore.

  • Is it possible to come over the time out issue for a function call in C#?

    - by infant programmer
    In my program I call a method xslTransform.Load(strXmlQueryTransformPath, xslSettings, new XmlUrlResolver()); The problem I am facing is: sometimes this function doesn't execute well within the time. Sometimes compiler raises the time out issue after a long time of trial.. which inturn causes this part of application to shut. That is what I want to avoid. So if it exceeds certain time say 10 seconds I need to recall the method. Is it possible to add some code lines adjacent to this, which can meet the requirement?

  • Is it possible to view Facebook news feeds page by page rather than loading it all as I scroll?

    - by oscilatingcretin
    If you want to scroll through your Facebook news feed (be it on the main feed, your personal feed, or in groups) to older parts, you have to scroll to the bottom, wait for the ajax load of the next part of the feed, and repeat. The problem with this is that, if you're scrolling down very far, the HTML document just gets bigger and bigger until your browser starts to die due to the overload of resources brought on by added HTML, text, and even images. This pretty much sets a limit to how far back you can scroll. Clicking on months and years on your personal feed has the same effect of cumulatively adding feed segments to the HTML document. I notice that this month/year feature is not available on the main feed and for groups. If there were a way to literally page through the feed so that only a single page's worth of feed data is loaded at a time, that would make scrolling through it much more doable.

  • AWS Free Usage Tier + Cloudflare... possible?

    - by crashintoty
    If I throw my MySQL/PHP app up on a Amazon EC2 instance (using their AWS Free Usage Tier program) and couple it with CloudFlare (the free plan of course) roughly how many daily visitors can I comfortably handle before performance starts to suffer? Just looking for a rough estimate or educated guess - I understand this setup might be less than ideal but I'm still very curious nonetheless. Thanks in advance

  • Visual Studio 2010: Is it possible to force editor to use ANSI rather than UTF-8?

    - by Mark Redman
    I am having issues with some files in automated processes, specifically with batch files and sql files. Visual Studio seems to create these as UTF-8 rather than ansi and adds some kind of special characters to the beginning of the file (I think this is a called a pre-amble) This breaks running batch files and running swl files through osql.exe. I have had issues myself in the past in creating text files using C#, but can get around that through encoding. However its seems a bit strange I cant use Visual studio to create batch files and sql files in a database project for automation.

  • Is it possible to compute the minimum of three numbers by using two comparisons at the same time?

    - by Milo Hou
    I've been trying to think up of some way that I could do two comparisons at the same time to find the greatest/least of three numbers. Arithmetic operations on them are considered "free" in this case. That is to say, the classical way of finding the greater of two, and then comparing it to the third number isn't valid in this case because one comparison depends on the result of the other. Is it possible to use two comparisons where this isn't the case? I was thinking maybe comparing the differences of the numbers somehow or their products or something, but came up with nothing. Just to reemphasize, two comparisons are still done, just that neither comparison relies on the result of the other comparison. EDIT: what about: boolA = A^2 + B^2 < C^2 boolB = A > B if boolA then max=C else if boolB then max=A else max=B

  • Is it possible to run a compiled program with Xcode on Mac OS X in FreeBSD? (Objective-C/Cocoa)

    - by Eonil
    Hi. I have a plan to build a web-site which running CGI made with Cocoa. My final goal is develop on Mac OS X, and run on FreeBSD. Is this possible? As I know, there is a free implementation of some NextStep classes, the GNUStep. The web-site is almost built with only strings. I read GNUStep documents, classes are enough. DB connection will be made with C interfaces. Most biggest problem which I'm concerning is linking and binary compatibility. I'm currently configuring FreeBSD on VirtualBox, but I wanna know any possibility informations about this from experts. This is not a production server. Just a trial. Please feel free to saying anything.

  • Possible reasons for high CPU load of taskmgr.exe process on VM?

    - by mjn
    On a VMware virtual machine which has severe performance problems I can see a constant average of 20+ percent CPU load for the TASKMGR.EXE (task manager) process. The apps running on this server have lower load, around 4 to 10 percent average. The VM is running Windows 2003 Server Standard with 3.75 GB assigned RAM. I suspect that the task manager CPU load has something to do with other VM instances on the VMWare server but could not see a similar value on internal ESXi systems (the problematic VM runs in the customers IT).

  • SQL Server on VMWare - is transaction log corruption possible?

    - by demp
    Scenario: SQL Server 2005 or 2008, Windows 2008 OS. Running in a VM hosted on VMWare ESX server. Is there any known issue with VMWare when it caches pass-through write request and it never reaches the disk, while SQL Server "thinks" that write actually happened? This may lead to transaction log corruption in case of power failure or VM reboot. Just overheard the conversation but couldn't find it in relation to ESX.

  • Is it possible to reinterpret pointer as dimensioned array reference?

    - by aaa
    hi. Suppose I have some pointer, which I want to reinterpret as static dimension array reference: double *p; double (&r)[4] = ?(p); // some construct? // clarify template< size_t N> void function(double (&a)[N]); ... double *p; function(p); // this will not work. // I would like to cast p as to make it appear as double[N] Is it possible to do so? how do I do it?

  • Is it possible to cause artificial network packet loss or latency?

    - by nbolton
    I'm trying to reproduce some issues on a deployed application where the MSSQL server and client are running in two separate machines. I think there may be network issues between the two machines, so I'd like to try and reproduce these conditions on two Hyper-V virtual machines (on the same virtual server). Of course, the network for these virtual machines is "local" so it's actually far from the conditions in a live environment. Is there a program I can run on either virtual machine which will degrade the network performance? Or maybe any other work arounds? For example, one way to reproduce the conditions may be to run the VMs on separate Hyper-V servers in geographically dispersed locations (so the SQL traffic goes over VPN or something) -- but this is a little long winded I think. There must be a simpler way.

  • Custom attributes in Active Directory - determining usage/function and possible removal options?

    - by HopelessN00b
    I've bumped into a highly-customized Active Directory environment (2003 FL) that's got me wondering if there's any particularly easy way to figure out what a custom attribute's function is, and what, if anything, is "using" that particular attribute. And then what some good options for potentially removing custom attributes from the schema might be. Aside from a restore or starting from scratch. If such an option exists. For example, I think I can be fairly certain what the "isDumbass" attribute with a value of TRUE means, but not so much with "IRPextCONST", containing a value of 393684. Likewise, I'd think it should be pretty safe to delete the "isDumbass" attribute, but would like to a) be sure and b) find out what's querying or updating that value anyway, because I suspect that anything using that attribute might be next on the list of things to remove. Ideally, without having to run a search on the contents of every custom script and bit of source code I can get my hands on, of course. And finally, aside from rebuilding from scratch, or doing an authoritative AD restore from backups that don't exist... is there a way to delete a given custom attribute? (Not blank the value, but actually delete the attribute from the schema - some folks would rather not have attributes like "FaggotMeter" and "DouchebagCounter" hanging around.) I've been able to find and successfully test a method on Windows 2k, but it seems like Microsoft disabled this option in SP4, and the domain in question is a 2003 functional level.

  • Is it possible to make a script/plugin for Finder to toggle hidden files without relaunching?

    - by Andrei
    There are several ways how to toggle hidden files in Finder - via a shell command, or AppleScript, or Automator action, or even a Dashboard widget. All of them are doing the same thing and unfortunately require to close and reopen Finder windows, which is quite annoying. On the other hand, for the Open File dialog one can easily toggle hidden files by pressing Command+Shift+Period. Is it possible to make a script or plugin for Finder to toggle hidden files w/o relaunching? How would you make it?

  • Is it possible to copy a set of files, but automatically skip if file already exists?

    - by awe
    I know that the copy command has an option to automatically replace a file if it already exists, but I want to know if it is a way to copy the files only if they not already exist (/Y). I do not know the actual file names in the batch code, as I copy from the source using wildcards in the copy command: copy *.zip c:\destination The reason I want this instead of automatic overwrite is that the files are large, and to skip existing would save a lot of execution time.

  • MySQL : select/join on strings as fieldnames - is this possible?

    - by Dylan
    I can retrieve all column names from table 'categories' with : SELECT col.column_name FROM information_schema.columns AS col WHERE col.table_schema= database() and col.table_name = "categories" This produces a resultset like this : column_name ----------------- categoryID name description I can retrieve all values for a specific category with : SELECT * FROM categories AS c WHERE c.categoryID=12345 this results in a resultset like this: categoryID | name | description ------------------------------------------------ 12345 | test | this is a test Now I would like to get some kind of join of above selects to get a resultset that looks something like this : fieldname | value ---------------------------------------- categoryID | 12345 name | test description | this is a test Does anyone know if this is possible ? Can you do a join on strings that come from another select ?? The reason for this is that I'm writing a universal stored procedure that outputs all fields + their values from a table, without knowing what fields there are in the table. (The tablename is given in a parameter)

  • Is it possible to print on a networked Windows Print server from an AIX server, without using remote printer queues?

    - by Stringent Software
    I have an application on an AIX server (v5.3) that needs to print via a Windows Print Server over the LAN. The simplest way to do this is to use SMIT to setup a remote print queue - which I've done on the test environment - but the IT department have refused to set up a remote print queue on the Production server. I don't have root access to the Production server. Is there any other method for connecting the app to the print server that doesn't involve print queues on the AIX box?

  • Is it possible to change the look and feel of remote X applications running under Xming?

    - by Rasive
    I am running Eclipse remotely right now, in Xming on my Windows pc, through an ssh tunnel from my laptop running Ubuntu 11.10. As seen below, it doesn't look that bad, but it seems that my applications defaults to the standard theme when it cannot find any others for GTK+ applications. Is there anything I can do about this? Also it would be nice if I could do something about the font settings to make it more easily readable.

  • Is it possible to edit a PDF file directly?

    - by rossmcm
    I have a PDF file that is produced as part of a help file compilation. There is always late breaking stuff which goes into a text file (e.g. "What's new in this version" type of stuff) and while Help and Manual allows you to include stuff from a text file it only works for the CHM output and not for the PDF. I'm wondering if I can do it by generating a unique placeholder string instead and then using some tool (I may need to write one) to do a search and replace of that unique string with the contents of the late breaking info text file. Is this feasible? Or will it break some sort of internal structure?
