  • Do you think natively compiled languages have reached their EOL?

    - by Yuval A
    If we look at the major programming languages in use today it is pretty noticeable that the vast majority of them are, in fact, interpreted. Looking at the largest piece of the pie we have Java and C# which are both enterprise-ready, heavy-duty, serious programming languages which are basically compiled to byte-code only to be interpreted by their respective VMs (the JVM and the CLR). If we look at scripting languages, we have Perl, Python, Ruby and Lua which are all interpreted (either from code or from bytecode - and yes, it should be noted that they are absolutely not the same). Looking at compiled languages we have C which is nowadays used in embedded and low-level, real-time environments, and C++ which is still alive and kicking, when you want to get down to serious programming as close to the hardware as you can, but still have some nice abstractions to help you with day to day tasks. Basically, there is no real runner-up compiled language in the distance. Do you feel that languages which are natively compiled to executable, binary code are a thing of the past, taken over by interpreted languages which are much more portable and compatible? Does C++ mark an end of an era? Why don't we see any new compiled languages anymore? I think I should clarify: I do not want this to turn into a "which language is better" discussion, because that is not the issue at hand. The languages I gave as example are only examples. Please focus on the question I raised, and if you disagree with my statement that compiled languages are less frequent these days, that is totally fine, I am more than happy to be proved mistaken.

  • Exchange 2003 Sending Double E-mails?

    - by Beuy
    Hello there, We have an exchange 2003 single-machine setup that is behaving very oddly. For various users it sends the same e-mail twice (I've checked the logs and each e-mail has a unique mail identifier which confirms that the problem is not the same e-mail being received twice, but it being sent twice) I've done a quick search and found tons of information regarding POP3/IMAP connectors etc, however these Employes are using Outlook 2003/2007 in Cached Mode. The Symantec AntiVirus for Mail is also not causing the issue, it's correctly scanning both e-mails coming through. Any ideas?

  • Win 7 accessing large files uses 100% RAM

    - by user181276
    Running Win 7 64-bit SP1 with 8 GB RAM. I first noticed this problem when using the GUI to copy some large (5+ GB) files from one disk to another. What happens is the physical memory in use rises quite quickly to 100% and the system comes to a crawl. If I just start to access the file in a media player (it is a movie) the memory usage climbs up slowly but eventually reaches 100%. When copying the same files via XCOPY I do not have this problem. Using RAMMAP I see most of the memory usage is under "Mapped File" and is allocated under the "Active" column. If I select "Empty System Working Set" the RAM usage drops back down but then starts to climb back up. Any ideas on what I can check/test to eliminate this issue?

  • AABB Sweeping, algorithm to solve "stacking box" problem

    - by Ivo Wetzel
    I'm currently working on a simple AABB collision system and after some fiddling the sweeping of a single box vs. another and the calculation of the response velocity needed to push them apart works flawlessly. Now on to the new problem, imagine I'm having a stack of boxes which are falling towards a ground box which isn't moving: Each of these boxes has a vertical velocity for the "gravity" value, let's say this velocity is 5. Now, the result is that they all fall into each other: The reason is obvious, since all the boxes have a downward velocity of 5, this results in no collisions when calculating the relative velocity between the boxes during sweeping. Note: The red ground box here is static (always 0 velocity, can utilize spatial partitioning ), and all dynamic static collisions are resolved first, thus the fact that the boxes stop correctly at this ground box. So, this seems to be simply an issue with the order the boxes are sweept against each other. I imagine that sorting the boxes based on their x and y velocities and then sweeping these groups correctly against each other may resolve this issues. So, I'm looking for algorithms / examples on how to implement such a system. The code can be found here: https://github.com/BonsaiDen/aabb The two files which are of interest are [box/Dynamic.lua][3] and [box/Manager.lua][4]. The project is using Love2D in case you want to run it.

  • Does a Required Restart for Windows Update log an event? If so what is the source/id?

    - by Beuy
    Hi there, Does anyone happen to know if a required restart in order to apply Windows Updates creates a entry in the event log? If so which log is it under, and what is the source/id? I have a legacy system that needs to an account, constantly logged into console for applications to function as required (Some old PROCOMS modem software for customers without Internet access but a telephone (Dial-up? Separate issue, don't get me started -.-)). When an update is applied to this machine that requires a restart (Server 2003) I would like an e-mail alert to be sent.

  • Server freeze (Disk I/O possibly)

    - by user973917
    I have a Windows Server 2008 machine that is resyncing disks after a powerloss. The issue is that the system becomes unresponsive after about 10 minutes. We've checked with resource monitor and found that the CPU's aren't maxed; but the disk I/O is well over 250MB/s. We've attempted copying data from 1 disk to another; bypassing syncing of disks and this too causes the machine to freeze after about 10 minutes of copying data. I have attempted to let the machine resync the disks for a few days with the machine on in this "frozen" state. By frozen I mean that NOTHING works on the machine, it's completely unresponsive; no mouse movement, etc. I want to know how I would go about definitively checking if this is Disk I/O that is freezing the system. I know that disk I/O can freeze a system; but what can I use to run tests to be sure?

  • Glusterfs : 'No route to host' for fstab mount in CentOS

    - by son_of_fire
    I am using glusterfs, and am using fstab in this way: <IPADDRESS>:/<VOLUMENAME> /some/mount/point glusterfs defaults,_netdev 0 0 but the logs for the mount continue to say the following. [<TIMESTAMP>] E [socket.c:2161:socket_connect_finish] 0-<VOLUMENAME>-client-1: connection to <IPADDRESS>:24007 failed (No route to host) I know this is not true, since when the system is up and running, I can easily issue a mount and the volume gets mounted. (I've done this by using rc.local) after reading more I have seen that using _netdev is preferred, and that if the host cannot be reached netfs will remount the volume after the network comes up, but that is not happening. (netfs is running). Is there a way to make the mount happen at a different time without using a script? (I would prefer to use fstab to manage the mounting even though I can use a script.)

  • Website with large number of users keeps going down due to memory leaks:Tomcat6 and Java 6

    - by user1766478
    We host many websites on one of our two virtual servers. We use tomcat 6 and Java 6. It is an MVC model with a hibernate like layer. The problem is, one of our biggest clients with the most number of members, keeps crashing the server every 6-8 hours(precisely in the mornings when most members login) We have been having this issue for 4 days now. Trying to figure out the problem but we suspect memory leaks. Any suggestions?

    - by Moshe
    I'm trying to repair an xp pro install using the repair cd The issue is a corrupted registry. Following the MS help center instructions, I made a batch file to replace the registry. It's not working. Does the CD need to match the edition and service pack of Windows on the disc? How can I tell (retroactively, with no Windows access) what edition/sp is installed? Any other ideas/thoughts? I am considering an pgrade install to Windows 7... TH\hanks!

  • Is it possible to run pgp 6.5.8 freeware on Windows 7 64 bit machine?

    - by Johnny Holmes
    I am trying to get the PGP Command Line -Freeware Version 6.5.8 by Networks Associates working on a Wndows 7 64 bit machine. Does anyone know if it is possible? I installed it in C:\pgp when i run pgp, it keeps telling me that it can't find the pgp.cfg file. My PGPPATH is defined and set to C:\pgp I have also included this path in my Path variable Can anyone tell me what i am doing wrong. The documentation states that: "The first time you start PGP, the software checks to see if the environment variable PGPPATH is defined. If PGPPATH is defined, the software puts the pgp.cfg in the %PGPPATH% directory" Edit: This is most likely a Windows 7 professional folder rights issue, since the file pgp.cfg can't get written. I tried my best given the folder full rights, but im not 100% confident that i did it right. Anyone help me?

  • Skype message sync and notifications - Windows 8

    - by Raykud
    The problem is that my messages don't seem to sync and neither do I get notifications from the Windows Store App. I have both, the desktop program and the Windows Store App, the problem is that whenever someone messages me I do not receive a notification of the App but I get one from the desktop program. The Skype app is running in the background and does not have disabled the notifications neither have turned on sleep notifications. I have to manually open the app and moreover, open the chat window of the one who is talking to me, then wait like 10 minutes and then the chat will get syncronized. in short: Notifications don't work even: if computer unlocked and Skype is running in background if computer unlocked and Skype is running in foreground These doesn't seem to help: Reboot doesn't affects skype. Having only the App opened. Uninstalling/reinstalling Is there a way to fix this? or is this an issue with the Skype app in Windows 8?

  • Apache misbehaving (returning 404s)

    - by OC2PS
    CentOS 6.4 64-bit Apache 2.4.6 PHP-FPM 5.5.4 Homepage from root loads fine http://csillamvilag.com But all other pages return 404 (CMS is WordPress). I am also able to access and log into WordPress backend. Additionally, Menalto Gallery 3 seems to be loading ok http://csillamvilag.com/kepek/ but all OpenCart pages return 404 http://csillamvilag.com/shop/ or http://csillamvilag.com/shop/hu/ Apache is running as user apache. All relevant WordPress and OpenCart files are owned by user apache. I have a suspicion that it might be a rewrite issue, but I checked .htaccess for both WordPress and OpenCart, and they look ok. e.g. WordPress/root .htaccess is: # BEGIN WordPress <IfModule mod_rewrite.c> RewriteEngine On RewriteBase / RewriteRule ^index\.php$ - [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.php [L] </IfModule>

  • Security exception in Twitterizer [closed]

    - by Raghu
    Possible Duplicate: Security exception in Twitterizer Hi, We are using Twitterizer for Twitter integration to get the Tweets details. When making call to the method OAuthUtility.GetRequestToken, following exception is coming. System.Security.SecurityException: Request for the permission of type 'System.Net.WebPermission, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed. When the application is hosted on IIS 5, the application works fine and the above error is coming only when the application is hosted in IIS 7 on Windows 2008 R2. and the method OAuthUtility.GetRequestToken throws above exception. It seems the issue is something with code access security. Please suggest what kind of permissions should be given to fix the security exception. The application has the Full Trust and I have even tried by registering the Twitterizer DLL in GAC and still the same error is coming. I am not sure what makes the difference between IIS 5 and IIS 7 with regards to code access security to cause that exception. Any help would be greatly appreciated. Thanks in advance. Regards, Raghu

  • Monitor for HD video editing

    - by Kato
    I have been researching for days and nights on a good monitor to buy for a Mac Pro with an ATI Radeon 2600 XT (256mb). It will be used extensively for HD video editing (1080p) and photo editing, and likely also digital/3D animation next year(a lot of FCP + CS4). I am a student, so money is a little bit of an issue, but I want something that I'll be able to use semi-professionally after I'm done school, and am willing to finance something if it is worth the cost. I'm HOPING for something under $1000 though. The IPS Ultrasharps from Dell seem to be getting good reviews from other video editors. Accurate colour correction is a concern for me (hopefully something that covers Adobe spectrum), as well as a decent response time, HD resolutions, and DVI port. Also something with good gradient/definition in black areas, as this is difficult for editing on most LCDs. 1X1 pixel, brightness, good DVD playback etc. Hopefully this is not impossible to find for under $2000!

  • How to add a disclaimer to forwarded messages to outside domains in Exchange 2013?

    - by Vinícius Ferrão
    I would like to implement some kind of filter to add a disclaimer message within emails forwarded to outside domains. Today we have some users that setup filters to forward messages to external mail servers, as example @gmail addresses. So this kind of forward should be marked with the disclaimer message. Not the normal fwd messages. We have a Postfix mailfiltering gateway too, if it's simpler to implement this on the mail filter, it could be a viable option. What would be the best approach to handle this issue? Thanks,

  • MikroTik ipv6 Tunnel

    - by MikeSmitty
    I've got a MikroTik router set up with the latest stable OS on it, and I just set up an ipv6 tunnel with Hurricane Electric, but I'm having an odd issue with it. I can't ping anything until I first ping the tunnel endpoint on HE's side. After that I can ping any ipv6 address fine, but give it a little time (say, maybe 30 sec) and I can't ping any ipv6 addresses again. Whenever it stops allowing ping to go through I notice the counter on my firewall rule that drops invalid connections goes up. this is my ipv6 firewall config: add action=accept chain=input comment="" connection-state=established \ disabled=no in-interface=sit1 add action=accept chain=input comment="" connection-state=related disabled=no \ in-interface=sit1 add action=accept chain=input comment="" disabled=no in-interface=bridge \ src-address=ipv6_address_here/64 add action=drop chain=input comment="" connection-state=invalid disabled=no \ in-interface=sit1 add action=drop chain=input comment="" disabled=no in-interface=sit1 Any ideas on what it could be?

  • DPMS, keep screen off when lid shut

    - by Evan Teran
    I have a laptop running linux. In my xorg configuration, I have DPMS setup so that the screen automatically turns off during several events. In addition to that I have to the following script tied to ACPI lid open/close events: #!/bin/sh for i in $(pidof X); do CMD=$(ps --no-heading $i) XAUTH="$(echo $CMD | sed -n 's/.*-auth \(.*\)/\1/p')" DISPLAY="$(echo $CMD | sed -n 's/.* \(:[0-9]\) .*/\1/p')" # turn the display off or back on export XAUTHORITY=$XAUTH /usr/bin/xset -display $DISPLAY dpms force $1 done Basically, this script takes one parameter ("on" or "off") then iterates through all of my running X sessions and either turns on or turns off the monitor. Here's my issue. When I close the lid of the laptop, the screen goes off as expected, but if a mouse event occurs (like if something bumps into the table...) then the screen turns back on even though it is closed (I can see the light through the side of the laptop). Is there a way to prevent the screen from turning on during a mouse event if the lid is closed?

  • Ubuntu 12.04, xbmc, opengl, intel motherboard

    - by Sean Hagen
    I've got an HTPC that I built myself, with a Asus P5G41T-M Motherboard. It's got an on-board HDMI port, and I've been using that with no problems. I started out with Mythbuntu ( an older version ), and recently updated to 12.04.1 LTS without any issues. I've been thinking about trying out XBMC for a while, and I decided to give it a go. Unfortunately, I seem to be running into quite a few issues. I got XBMC installed from the repos without any issues, but when I try to run it from a console, a box pops up with the following: XBMC needs hardware accelerated OpenGL rendering. Install an appropriate graphics driver. Please consule XBMC Wiki for supported hardware http://wiki.xbmc.org/?title=Supported_hardware In the console, it prints out the following: X Error of failed request: BadRequest (invalid request code or no such operation) Major opcode of failed request: 136 (GLX) Minor opcode of failed request: 19 (X_GLXQueryServerString) Serial number of failed request: 12 Current serial number in output stream: 12 When I run vainfo, I get this: libva: VA-API version 0.32.0 libva: va_getDriverName() returns 0 libva: Trying to open /usr/lib/x86_64-linux-gnu/dri/i965_drv_video.so libva: va_openDriver() returns 0 vainfo: VA-API version: 0.32 (libva 1.0.15) vainfo: Driver version: Intel i965 driver - 1.0.15 vainfo: Supported profile and entrypoints VAProfileMPEG2Simple : VAEntrypointVLD VAProfileMPEG2Main : VAEntrypointVLD The file /usr/lib/x86_64-linux-gnu/dri/i964_drv_video.so exists: # ls -l /usr/lib/x86_64-linux-gnu/dri/i965_drv_video.so -rw-r--r-- 1 root root 628728 Mar 29 2012 /usr/lib/x86_64-linux-gnu/dri/i965_drv_video.so And in /var/log/Xorg.0.log the following error pops up: GLX error: Can not get required symbols. I'm not really sure where to go from here. I've tried searching all over for how to fix this problem.

  • Outlook 2003 (with Exchange 2007) error: You cannot respond to a meeting without an Organizer

    - by Hissohathair
    The company recently upgraded to Exchange 2007. Since the upgrade users who are still on Outlook 2003 (SP3) get the following error for some meeting requests: You cannot respond to a meeting without an organizer. You must add an Organizer field to the item. The item has an organizer field filled in. Exchange is 2007 with SP1 MS Office (incl Outlook) is 2003 with SP3 Some users are using iPhones to accept / reject meetings. The iPhones never get an error like this. There are no delegates for the user attempting to accept or reject the meeting. Sometimes the meeting was previously accepted, sometimes not. We have not detected a pattern in the meeting requests that trigger the issue. I've found a few people asking the same question on other websites but no answers. Experts Exchange claims to have an answer but from looking at the discussion at the bottom of the page I'm pretty sure they don't.

  • How to use WeirdX applet instead of X11 for remote connections in Mac OS X?

    - by penyuan
    When I am away, I've got an Apple PowerBook set up to use X11 forwarding with SSH to connect to a remote iMac in my room. Whenever I start X client programs on the client iMac, X11 would start on my PowerBook, which is OK. Question: Is it possible to change my settings so that the WeirdX applet I have on my PowerBook will take care of the X client programs instead of the default X11? Is there a config file I can edit to chance the $DISPLAY variable, and what should I set it to? Is this even the issue? Thank you very much.

  • DIVIDE vs division operator in #dax

    - by Marco Russo (SQLBI)
    Alberto Ferrari wrote an interesting article about DIVIDE performance in DAX. This new function has been introduced in SQL Server Analysis Services 2012 SP1, so it is available also in Excel 2013 (which still doesn’t have other features/fixes introduced by following Cumulative Updates…). The idea that instead of writing: IF ( Sales[Quantity] <> 0, Sales[Amount] / Sales[Quantity], BLANK () ) you can write: DIVIDE ( Sales[Amount], Sales[Quantity] ) There is a third optional argument in DIVIDE that defines the result in case the denominator (second argument) is zero, and by default its value is BLANK, so I omitted the third argument in my example. Using DIVIDE is very important, especially when you use a measure in MDX (for example in an Excel PivotTable) because it raise the chance that the non empty evaluation for the result is evaluated in bulk mode instead of cell-by-cell. However, from a DAX point of view, you might find it’s better to use the standard division operator removing the IF statement. I suggest you to read Alberto’s article, because you will find that an expression applying a filter using FILTER is faster than using CALCULATE, which is against any rule of thumb you might have read until now! Again, this is not always true, and depends on many conditions – trying to simplify, we might say that for a simple calculation, the query plan generated by FILTER could be more efficient – but, as usual, it depends, and 90% of the times using FILTER instead of CALCULATE produces slower performance. Do not take anything for granted, and always check the query plan when performance are your first issue!

  • How do I configure custom routes when an interface is configured?

    - by ManicDee
    Other Superuser questions have addressed the issue of adding custom routes to access e.g.: multiple networks of a corporate network through one interface, while accessing the Internet through another interface. So assuming that I have a script to add specific routes when en0 is configured, and a separate script to add specific routes when en1 is configured, is there some way I can trigger those scripts to run automatically when Mac OS X/Darwin starts and configures those interfaces? Back in my Linux days, it was possible to add an option in /etc/network/interfaces along the lines of: iface eth0 inet dhcp up /usr/local/sbin/eth0-routes-up Is there something similar for Mac OS X?

  • Designing javascript chart library

    - by coolscitist
    I started coding a chart library on top of d3js: My chart library. I read Javascript API reusability and Towards reusable charts. However, I am NOT really following the suggestions because I am not really convinced about them. This is how my library can be used to create a bubble chart: var chart = new XYBubbleChart(); chart.data = [{"xValue":200,"yValue":300},{"xValue":400,"yValue":200},{"xValue":100,"yValue":310}]; //set data chart.dataKey.x = "xValue"; chart.dataKey.y = "yValue"; chart.elementId = "#chart"; chart.createChart(); Here are my questions: It does not use chaining. Is it a big issue? Every property and function is exposed publicly. (Example: width, height are exposed in Chart.js). OOP is all about abstraction and hiding, but I don't really see the point right now. I think exposing everything gives flexibility to change property and functionality inside subclasses and objects without writing a lot of code. What could be pitfalls of such exposure? I have implemented functions like: zooming, "showing info boxes when data point is clicked" as "abilities". (example: XYZoomingAbility.js). Basically, such "abilities" accept "chart" object, play around with public variables of "chart" to add functionality. What this allows me to do is to add an ability by writing: activateZoomAbility(chartObject); My goal is to separate "visualization" from "interactivity". I want "interactivity" like: zooming to be plugged into the chart rather than built inside the chart. Like, I don't want my bubble chart to know anything about "zooming". However, I do want zoomable bubble chart. What is the best way to do this? How to test and what to test? I have written mixed tests: jasmine and actual html files so that I can test manually on browser.
