• Erlang-style light-weight processes in .NET

  - by alexey

  Is there any way to implement Erlang-style light-weight processes in .NET? I found some projects that implement Erlang messaging model (actors model). For example, Axum. But I found nothing about light-weight processes implementation. I mean multiple processes that run in a context of a single OS-thread or OS-process.

• Eventlet and locking

  - by TheDude

  Since Eventlet uses green threading and asynchronous I/O, do I still need to set locks before accessing objects? My understanding is that greenlets are all part of one thread and locking isn't necessary. Can anyone confirm or deny this?

• Product Recommendation: Good job scheduler for windows servers?

  - by Bret Fisher

  Looking for a mostly-GUI tool that is low cost (less then $1k, but not required) and allows you to create scheduled tasks and jobs without writing vbscript, batch files, or powershell. Something simple that speaks SMB/CIFS, SMTP, LDAP, etc. for such things as "delete some files based on a list of folders from this text file" or "disable all users with expired accounts" or "delete all disabled users not in this AD group". I've seen some of the big multi-OS enterprise task automation systems and they just look way overkill. We're a windows-only shop, Server 2003 or newer and there's got to be a simple non-agent based product that is drag-n-drop for some of this basic automation. Today we use all three languages mentioned above, and the scripts are not as reliable as a workflow-based-tool would be. Thanks.

• Servlet IOException when streaming a Byte Array

  - by MontyBongo

  I occasionally get an IOException from a Servlet I have that writes a byte array to the outputstream in order to provide a file download capability. This download servlet has a reasonable amount of traffic (100k hits a month) and this exception occurs rarely, around 1-2 times a month. I have tried recreating the exception by using the exact same Base64 String and no exception is raised and the Servlet behaves as designed. Is this IO Exception being caused by something outside my applications control? For example a network issue or the user resetting the connection? I have tried to google the cause of an IOException at this point in the stack but to no avail. The environment is running Tomcat 5.5 on CentOS 5.3 with an Apache HTTP Server acting as a proxy using proxy_ajp. ClientAbortException: java.io.IOException at org.apache.catalina.connector.OutputBuffer.realWriteBytes(OutputBufferjava:366) at org.apache.tomcat.util.buf.ByteChunk.append(ByteChunk.java:352) at org.apache.catalina.connector.OutputBuffer.writeBytes(OutputBuffer.java:392) at org.apache.catalina.connector.OutputBuffer.write(OutputBuffer.java:381) at org.apache.catalina.connector.CoyoteOutputStream.write(CoyoteOutputStream.java:89) at org.apache.catalina.connector.CoyoteOutputStream.write(CoyoteOutputStream.java:83) at com.myApp.Download.doPost(Download.java:34) at javax.servlet.http.HttpServlet.service(HttpServlet.java:710) at javax.servlet.http.HttpServlet.service(HttpServlet.java:803) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:269) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:188) at org.apache.catalina.core.ApplicationDispatcher.invoke(ApplicationDispatcher.java:691) at org.apache.catalina.core.ApplicationDispatcher.processRequest(ApplicationDispatcher.java:469) at org.apache.catalina.core.ApplicationDispatcher.doForward(ApplicationDispatcher.java:403) at org.apache.catalina.core.ApplicationDispatcher.forward(ApplicationDispatcher.java:301) at com.myApp.EntryServlet.service(EntryServlet.java:278) at javax.servlet.http.HttpServlet.service(HttpServlet.java:803) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:269) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:188) at com.myApp.filters.RequestFilter.doFilter(RequestFilter.java:16) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:215) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:188) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:210) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:172) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:117) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:108) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:151) at org.apache.coyote.ajp.AjpAprProcessor.process(AjpAprProcessor.java:444) at org.apache.coyote.ajp.AjpAprProtocol$AjpConnectionHandler.process(AjpAprProtocol.java:472) at org.apache.tomcat.util.net.AprEndpoint$Worker.run(AprEndpoint.java:1286) at java.lang.Thread.run(Thread.java:636) Caused by: java.io.IOException at org.apache.coyote.ajp.AjpAprProcessor.flush(AjpAprProcessor.java:1200) at org.apache.coyote.ajp.AjpAprProcessor$SocketOutputBuffer.doWrite(AjpAprProcessor.java:1285) at org.apache.coyote.Response.doWrite(Response.java:560) at org.apache.catalina.connector.OutputBuffer.realWriteBytes(OutputBufferjava:361) And the code in the Download Servlet: @Override protected void doPost (HttpServletRequest request, HttpServletResponse response) throws ServletException, java.io.IOException { try { response.setContentType("application/pdf"); response.setHeader("Pragma", ""); response.setHeader("Cache-Control", ""); response.setHeader("Content-Disposition", "Inline; Filename=myPDFFile..pdf"); ServletOutputStream out = response.getOutputStream(); byte[] downloadBytes = Base64.decode((String)request.getAttribute("fileToDownloadBase64")); out.write(downloadBytes); } catch (Base64DecodingException e) { e.printStackTrace(); response.getOutputStream().print("An error occurred"); } }

• What are shared by multi threads in the same process?

  - by skydoor

  I found that each thread still has its own registers. Also has its own stack, but other threads can read and write the stack memory. My questions, what are shared by the multi threads in the same process? What I can imagine is 1) address space of the process; 2) stack, register; 3) variables Can any body elaborate it and add more?

• Internet cafe software for linux

  - by pehrs

  I have gotten a request to roll out a total of 8 internet cafe's in a large network. Budget is non-existent as it will all be done for a non-profit. I was planing to use Ubuntu and live-cds to minimize the amount of management required, but I can't seem to find any suitable internet cafe system that is Ubuntu based. The requirements are pretty basic: It needs to keep track of logged in time and log out users when their time it up. No billing will be done, it will just be used to ensure people can share the computers fairly. It should be possible to force logout from a central system. Users will be unskilled, so it has to have a GUI. What (preferably free, considering the shoe-string budget) software would you suggest to manage this?

• Accessing the MSP and PSP registers of the Cortex-M3 in C/C++ code using Keil's µVision

  - by Captain NedD

  I need to access the MSP and PSP registers (the main and process stack registers) of the Cortex-M3 processor. I'm writing in C/C++. The µVision and associated compiler doesn't let you do inline assembly for this Thumb-2 only core (and I'm not sure that'd be such a good idea anyway). I need to do this so that I can extract the immediate value of an svc instruction regardless of whether it was executed while in thread or handler mode. Thanks,

• Distributed sequence number generation?

  - by Jon

  I've generally implemented sequence number generation using database sequences in the past. e.g. Using Postgres SERIAL type http://neilconway.org/docs/sequences/ I'm curious though as how to generate sequence numbers for large distributed systems where there is no database. Does anybody have any experience or suggestions of a best practice for achieving sequence number generation in a thread safe manner for multiple clients?

• Will a ScheduledExecutorService create new threads as needed?

  - by Matt Ball

  I'm using Executors.newScheduledThreadPool() to create a ScheduledExecutorService, specifying the number of threads like so: int corePoolSize = 42; ScheduledExecutorService foo = Executors.newScheduledThreadPool(corePoolSize); According to the JavaDocs, the corePoolSize argument sets the number of threads to keep in the pool, even if they are idle. Does this mean that this ExecutorService implementation may create more than corePoolSize threads as needed, similar to a cached thread pool?

• Winlogon.exe causes C++ runtime error

  - by Evan

  Recently I've become unable to log into my Dell Precision M2400. It uses the Dell Controlpoint login GUI instead of the typical windows one, and has now started giving me a runtime error on winlogon.exe that ends with a c000021a BSOD. I have tried running through safe mode and a restore to the last known good setting with no success. Unfortunately by BIOS password is locked and the one IT guy with the password is on vacation and unreachable until after I leave for a business trip. Is there anyway to bypass the Dell logon screen and get to the default windows one? Thanks.

• Windows 7, file properties, date modified, how do you show seconds?

  - by Jordan Weinstein

  Anyone know a way to immediately show the seconds of a file's date modified property in the GUI? So if you create a file, any file in any directory, right-click and choose Properties, the date modified (if it's recent) will say something like "dd/mm/yyy hh:mm, one minute ago" - reminder this is in Windows 7. Windows XP did it normally. Then they changed something. If you wait a while, eventually you'll see the seconds, I'm not sure how long a while is, but this is incredibly annoying if you want to troubleshoot something that relies on the seconds of timestamps... is there a setting? registry key I can change perhaps? I'm literally using Chrome, pasting in the path of the directory to be able to see the seconds quickly (as a workaround) but would be nice to be able to use Win7.

• Implementation code of native methods

  - by Tapas Bose

  At first I want to let you know that this question is not related with What is native implementation in Java. I got many useful information from that thread. I want to know that are the codes of the native implementations available? I have jdk source code but I can not find the native codes for System.currentTimeMillis or Runtime.getRuntime().availableProcessors() or other native method. Thanks and regards.

• iphone, get the object count without performing a fetch?

  - by Andrew

  Hi, I seem to recall that it's possible to return the resulting object count from an NSPredicate in CoreData without actually performing a fetch, but I can't find any reference to this. Can someone confirm that I wasn't dreaming (sad dream to have!), and would this be safe to do in another thread? Thanks Andy

• Getting GPU clock speeds with SetupDiEnumDeviceInfo

  - by user157078

  Hi everyone! I posted a question earlier regarding obtaining GPU clock speeds, but I guess the thread appeared as already answered since someone had replied to it. I'd been advised by one of your members to try extracting GPU clock speeds using SetupDiEnumDeviceInfo. However, I looked around at some examples, like this one: http://www.codeproject.com/KB/system/DevMgr.aspx and nothing seemed to be displayed about the clock speed. Could someone please elaborate on how to achieve this, if at all possible? Thanks again

• Execute background program in bash without job control

  - by Wu Yongzheng

  I often execute GUI programs, such as firefox and evince from shell. If I type "firefox &", firefox is considered as a bash job, so "fg" will bring it to foreground and "hang" the shell. This becomes annoying when I have some background jobs such as vim already running. What I want is to launch firefox and dis-associate it with bash. Consider the following ideal case with my imaginary runbg: $ vim foo.tex ctrl+z and vim is job 1 $ pdflatex foo $ runbg evince foo.pdf evince runs in background and I get me bash prompt back $ fg vim goes foreground Is there any way to do this using existing program? If no, I will write my own runbg.

• Remote login/access on windows

  - by acidzombie24

  Hi I was wondering what software I can use to access my and other machines remotely? I used ssh which is nice but i don't know how it would be like on windows. (I assume its the same idea but windows console instead of a bash terminal?) Windows has a lot of applications that require GUI/MouseClicks. Actually I don't know a single ssh or vpn command line installer not that i'm complaining (but is helpful if you can mention some). I haven't use a VPN, is this taking control of a users screen/session? Or is it another instance/session as if you logged in as a different user on that box? What solutions are at my disposal for windows? (7)

• Ubuntu 10.4 Lucid Server Minimal Install: Slow terminal scrolling

  - by noname

  I have a minimal install of Ubuntu 10.4 Server for testing and learning purposes. There is a very annoying occurrance: whenever I try to "man dpkg" or any command that load a few screens length of text (eg. "ls -al") the redraw speed of the console is just way too slow. I can see how each new line causes the whole screen to redraw. Note: that this doesn't happen inside X. No gui is installed. I have been experimenting with adding vesafb to the grub line as some guides suggested, but no speedups happened. You might be able to reproduce this behaviour on your linux system by switching to terminal using CTRL+ALT+F1. Is there any way to speed scrolling up?

• X11Forwarding on MacOSX (Leopard/Snow Leopard)

  - by Shyam

  Hi, I have some remote boxes, which are a bunch of Mac Mini's. I access them now through SSH, and it fits my needs to do the maintenance. In the past, I used X11Forwarding with Linux boxes, when I was still using Debian myself, and I was able to run a specific application as if it was natively present (Firefox). I haven't succeeded to do this yet, but I assume because of the BSD underneath the fancy Apple GUI should be able to do such a task similar. I am aware of the remote administration, but I rather keep access limited to SSH on these boxes for inbound connections. Background information about the why's, tips, advice and comments are all helpful! Thanks!

• fedora13 mouse change -I Beam

  - by tom smith

  hi. sorry to have to ask such a basic question!! i've got fedora 13, trying to figure out how to change the "I Beam" pointer. earlier, i had a "thin" "I Beam" pointer in my gedit/term windows. now, I have a "thicker/shadow" kind of "I Beam" pointer when i move the mouse over the gedit/term windows. obviously, i've made some change, but i can't figure out what I changed, or where this attribute is set. i've checked google/irc, as well as looked through the "system-preferences-appearance" with no luck.. i saw the customize part of the gui, and could resize the "arrow" but nothing for the "I-Beam". this isn't critical, but it is anoying!! any thoughts/pointers would be helpful. thanks

• Can the Windows 8.1 update be applied without local terminal?

  - by Ben Voigt

  It is possible to access the Windows Store from a remote desktop session and initiate the Windows 8.1 Update from the Windows Store, but the update hangs after the first reboot, likely waiting for the user to accept the license check. This leaves the computer unusable remotely. Is there a way to pre-accept the license terms so that the update can complete autonomously? Perhaps an UNATTEND.XML such as would be used for an unattended clean install? Failing that, is there a way to connect with remote desktop during that phase of the install (it appears to be GUI-mode setup running with the usual Windows kernel and full OS)?

• Further explanation of IntentService

  Hi all, I was trying to get the purpose of the IntentService, and when should I use it? I tried to understand from the API, but not enough details on that one. Is there any analogy between this and running long-task on a working thread? Any further explanation and samples on why I would use IntentService would be very welcome. Thanks, ray.

• How to remove an "extra" (unwanted) network from a windows 2008 failover cluster?

  - by Trondh

  Hi, We had a severe crash on one node of our 2-node Windows 2008 / Exchange 2007 CCR Cluster the other day, and i tried to rebuild the node from scratch. I'm using this as a rough outline: http://edmckinzie.spaces.live.com/Blog/cns!687C72A5909E4230!508.entry?sa=641979772 The problem: Our cluster was originally setup with only one NIC per host, as this is supposedly supported in Win2008 (no dedicated heartbeat NIC). When I add my freshly installed node to the cluster, it shows up with two cluster networks, "Cluster Network 1" & 2. The existing node's NIC has been placed in one cluster network and my fresh installed has ended up in the other. I can't find anywhere in the GUI to choose which cluster network each physical NIC should be part of, but i KNOW I have done this before. Time is of the essence on this one, so I was hoping someone in here had the answer on the top of their head... Thanks for any pointers. regards, Trond Hindenes
