    - by xeross
    Hey, Somehow I keep getting a not enough resources to install device whenever I try to install the hamachi network adapter, and I tried installing other tunneling services but their network adapters can't seem to install either.

  • Slower/cached Linux file system required

    - by Chopper3
    I know it sounds odd but I need a slower or cached filesystem. I have a lot of firewalls that are syslog'ing their data to a pair of Linux VMs which write these files to their 'local' (actually FC SAN attached) ext3-formatted disks and also forward the messages to our Splunk servers. The problem is that the syslog server is writing these syslog messages as hundreds, sometimes thousands, of tiny ~4k writes per second back to our FC SAN - which can handle this workload right now but our FW traffic's going to be growing by at least a factor of 5000% (really) in coming months and that'll be a pain for the SAN, I want to fix the root cause before it's a problem. So I need some help figuring out a way of getting these writes cached or held-off in some way from the 'physical' disks so that the VMs fire off larger, but less frequent, writes - there's no way of avoiding these writes but there's no need for it to do so many tiny ones. I've looked at the various ext3 options, setting noatime and nodiratime but that's not made much of a dent in the problem. Obviously I'm investigating other file systems but thought I'd throw this out in case others have the same problem in the future. Oh and I can't just forward these messages to Splunk, our firewall team insist they're in their original format for diag purposes.

  • Create and copy a Windows Mobile 5.0 operating system image

    - by user20119
    We have several dozen Windows Mobile 5.0 devices (Symbol MC7095 handhelds equipped with embedded Verizon WLAN, if that matters) that all need the same software and configuration. We connect all of these devices via a USB cradle to add software to them via Microsoft ActiveSync, and then do several configuration changes directly on the handhelds themselves, in the OS. That process takes 30 minutes or more, per device. Is there any way to set up one device and take a 'disk image' of the entire OS/software, such that things could then be copied (quickly/easily) to the other devices? Is such a thing possible, with Windows Mobile devices?

  • DrawString only works in top-left part of form vb.net

    - by WillumMaguire
    Here is my code Public Class Form1 Public MyFormObject As Graphics = Me.CreateGraphics Public objFont = New System.Drawing.Font("arial", 20) Public a, b As Integer Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Randomize() For i = 1 To 10 a = CInt(Int(Rnd() * Me.Width)) b = CInt(Int(Rnd() * Me.Height)) MyFormObject.DrawString("text", objFont, System.Drawing.Brushes.Black, a, b) Next End Sub End Class As you can see, I have one button that draws the string "text" randomly in the form 10 times. My problem is that it will ONLY draw the string in the upper-left portion of the form, roughly 260x260 starting at 0,0. It literally cuts off the text if it goes beyond. Why is this? Shouldn't it work for the entire form?

  • Recover Partition-Table still present in running system

    - by theomega
    Hy, I accidentially overwrote the first 1M of my harddisk on linux (using dd). So, the partition-table is gone. I can still access all partition (except the first one) using /dev/sda2 (and so on), so the data is still there. I only need the partition boundaries to restore the table. How can I do this? The Linux-Kernel must still know them because all mount-points still work. fdisk -l /dev/sda doesn't work because it acctualy reads the partition table. Thanks!

  • Implementing a live voting system

    - by Will Eddins
    I'm looking at implementing a live voting system on my website. The website provides a live stream, and I'd like to be able to prompt viewers to select an answer during a vote initiated by the caster. I can understand how to store the data in a mySQL database, and how to process the answers. However: How would I initially start the vote on the client-side and display it? Should a script be running every few seconds on the page, checking another page to see if a question is available for the user? Are there any existing examples of a real-time polling system such as what I'm looking at implementing?

  • Reporting system for organization. Architecture advise required

    - by Andrew Florko
    We have several legacy & 3'd-party systems in organization that use several RDBMS vendors (& more specific data storages). Cross-system data reporting (as well as extra-reports that are not implemented in 3'd-party systems) is required with charts and population of templates (winword, excel). Reporting system is visioned as intranet web-site with custom user access to reports. We expect ~50 reports per day. Would you suggest to use BizTalk or any other integration software if commercial-department doesn't plan to buy anything expensive. Would you suggest to create centralized data storage for reporting that is populated regularly or rely on on-demand services that providers always up-to-request data. Thank you in advance!

Here is my code private void btnGo_Click(System.Object sender, System.EventArgs e) { this.Cursor = Cursors.WaitCursor; Application.DoEvents(); // Load the images. Bitmap bm1 = (Bitmap) (Image.FromFile(txtFile1.Text)); Bitmap bm2 = (Bitmap) (Image.FromFile(txtFile2.Text)); // Make a difference image. int wid = Math.Min(bm1.Width, bm2.Width); int hgt = Math.Min(bm1.Height, bm2.Height); Bitmap bm3 = new Bitmap(wid, hgt); // Create the difference image. bool are_identical = true; int r1; int g1; int b1; int r2; int g2; int b2; int r3; int g3; int b3; Color eq_color = Color.White; Color ne_color = Color.Transparent; for (int x = 0; x <= wid - 1; x++) { for (int y = 0; y <= hgt - 1; y++) { if (bm1.GetPixel(x, y).Equals(bm2.GetPixel(x, y))) { bm3.SetPixel(x, y, eq_color); } else { bm1.SetPixel(x, y, ne_color); are_identical = false; } } } // Display the result. picResult.Image = bm1; Bitmap Logo = new Bitmap(picResult.Image); Logo.MakeTransparent(Logo.GetPixel(1, 1)); picResult.Image = (Image)Logo; this.Cursor = Cursors.Default; if ((bm1.Width != bm2.Width) || (bm1.Height != bm2.Height)) { are_identical = false; } if (are_identical) { MessageBox.Show("The images are identical"); } else { MessageBox.Show("The images are different"); } //bm1.Dispose() // bm2.Dispose() }

  • wmpnetwk.exe hogging system resources

    - by cometbill
    I have recently noticed wmpnetwk.exe using a more than usual amount of processor cycles. I'm on Windows 7 Home Premium on a Netbook. I'm guessing it's a feature of Windows Media player that recently got turned on, possibly because of a Windows update or accidental key combination. I don't usually use Media player that often. Does anyone know if it is a feature that has recently turned on, and if so, how do I turn it off ?

  • "The requested operation could not be completed due to a file system limitation" 3202

    - by user46529
    I backup SQL Server database and it fails BACKUP DATABASE dd TO DISK = '\backupServer\backups\dd.bak' WITH COMPRESSION, CHECKSUM, NOFORMAT, INIT , BlockSize = 65536 , BufferCount = 2200 , MaxTransferSize = 4194304 The backup size is 3TB and I have 6TB free space on bacup server. I am using backup parameters per SQLCAT whitepaper. Everything works ok when I backup to local HDD and it always fails when I backup to network share. After about 6 hours. Can't find why. Thank you. Yes. The backup over the network is fastest and saves me 3Tb of local disk space :) Thanks for pointing to the memory issue. I left 4Gb to OS and it worked!

  • Solving linear system over integers with numpy

    - by A. R. S.
    I'm trying to solve an overdetermined linear system of equations with numpy. Currently, I'm doing something like this (as a simple example): a = np.array([[1,0], [0,1], [-1,1]]) b = np.array([1,1,0]) print np.linalg.lstsq(a,b)[0] [ 1. 1.] This works, but uses floats. Is there any way to solve the system over integers only? I've tried something along the lines of print map(int, np.linalg.lstsq(a,b)[0]) [0, 1] in order to convert the solution to an array of ints, expecting [1, 1], but clearly I'm missing something. Could anyone point me in the right direction?

  • Wastage of resources in Virtualization

    - by Sabeen Malik
    I am not sure if this is the write place to ask the question. However i hope it is. When looking for a VPS earlier today, I was trying to understand how each container would work in the background. Keeping in mind the fact that the operating system uses most of the power and power on a system, wouldn't having multiple operating systems in the same machine mean more wastage of resources. For instance if i was running centOS on a dedicated box and it was running lets say 20 background OS level processes. Then i go and install a virtualization platform and install 5 more centOS virtual machines in the same system which are exactly the same as the host operating system. Doesn't this mean duplication of those 20 processes 6 times? So internally the context switching is happening between 120 processes instead of 20?

  • Media meta file system for windows

    - by Chris Marisic
    I have a large assortment of media that is currently arranged using folders. As the library has grown I've started to notice that folders aren't the best at conveying meaning. Also as the number of folders serving as categories/tags has grown has lead to data duplication for not realizing it was already filed under a different tag. As I started to think about this I realized tag cloud visualization would be tremendously powerful and figured there has to be something like this out there.

  • Response.Redirect causes System.Threading.ThreadAbortException

    - by RandomBen
    When I use Response.Redirect(...) to redirect my form to a new page I get the error: A first chance exception of type 'System.Threading.ThreadAbortException' occurred in mscorlib.dll An exception of type 'System.Threading.ThreadAbortException' occurred in mscorlib.dll but was not handled in user code My understanding of this is that the error is being caused by the webserver aborting the remainder of the page the response.redirect was called on. I know I can add a second parameter to Response.Redirect that is called endResponse. If I set endResponse to True I still get the error but if I set it to False then I do not. I am pretty sure though that that means the webserver is running the rest of the page I redirected away from. Which would seem to be inefficient to say the least. Is there a better way to do this? Something other than Response.Redirect or is there a way to force the old page to stop loading where I will not get a ThreadAbortException?

  • TOP CPU usage for whole system

    - by heike
    I am using a machine that has using cat /proc/cpuinfo | grep processor | wc -l returning 8 I am trying to load the server using a load generator that I wrote, and capture the behaviour of TOP command for idle (as the software that is tested on server runs on ROOT). Doing the load as an increasing step function, I capture the idle state every second, and see the result. Strange thing is that when I increase the load every 1 minute, the idle state is infact increasing (??). This honestly does not make sense .. I thought with more load, the idle state will decrease, and the cpu usage will increase. Is there any reasonable explanation for this behaviour, maybe for the server utilization itself? Thanks for any feedback -- ok, no idea for the down vote. but I try to find this behaviour a lot, can not find any reasonable things to explain this ..

  • Suppress checking for changes on file system in Eclipse RCP

    - by panschk
    Okay, I guess this question is too difficult, but it's worth a try. I have an eclipse RCP application that edits HTML-files. I deal with the content of the files only in a W3C-Dom representation. There is some stuff that I can not do with that, so I the program edits each file each time after it is saved (save, save as). Of course, the file is then out of synch with the file system, and the next time I touch it, eclipse complains: "The file has been changed on the file system. Do you want to replace the editor contents with these changes? (Yes/No)" I do not want to load the changes into the editor ("No") Maybe there is a way to tell Eclipse programmatically to not check that file for changes, or to configure it to not check for changes on any file? edit: Everything has to be done either programatically or by editing some XML files. I can not expect the user to do anything;-)

  • Using system time directly to get random numbers

    - by Richard Mar.
    I had to return a random element from an array so I came up with this placeholder: return codes[(int) (System.currentTimeMillis() % codes.length - 1)]; Now than I think of it, I'm tempted to use it in real code. The Random() seeder uses system time as seed in most languages anyway, so why not use that time directly? As a bonus, I'm free from the worry of non-random lower bits of many RNGs. It this hack coming back to bite me? (The language is Java if that's relevant.)

  • Capturing system command output as a string

    - by dreeves
    Perl and PHP do this with backticks. For example: $output = `ls`; This code returns a directory listing into the variable $output. A similar function, system("ls"), returns the operating system return code for the given command. I'm talking about a variant that returns whatever the command prints to stdout. (There are better ways to get the list of files in a directory; the example code is an example of this concept.) How do other languages do this? Is there a canonical name for this function? (I'm going with "backtick"; though maybe I could coin "syslurp".)

  • Was Windows 95 an Operating System?

    - by shantnu
    This question maybe a bit historical, but we didn't have Superuser at the time. Around 2000 when I was starting my Computer science degree, a subject was Operating systems. The teacher asked us to list a few OS. I said Windows 95. I was immediately shot down. Windows 95 wasn't on OS, as it used DOS to boot up. The actual OS was DOS, Win 95 was just a graphical wrapper around it. I pointed that all trade magazines called Win95 an OS, but was told that they were run by laymen, and as a professional, I should know better. DOS was the only OS from Microsoft, at least till Win2K came out later that year. So 12 years on, I'm still not sure. Could Win 95 be considered an OS?
