• Long access time for static web page on virtual machine

  - by Karol

  My setup Windows 7 on workstation that I use at work (with domain) and home (no domain) Virtual machine (VMWare) that runs Arch Linux (I will call it just "Linux") with network interface in bridged mode. Linux serves web pages with Nginx. IP address of Linux machine is 192.168.0.16 and is added to C:\windows\system32\drivers\etc\hosts: 192.168.0.16 bridged bri IP address of Windows workstation is added to /etc/hosts: 192.168.0.10 workstation I can add more details to my setup description (I am not sure what is relevant). The question Often (but not always) it takes long time for a web browser (Firefox) to open static web page served by Linux. I am sure it is not a performance issue. To be more specific: it takes about ~20 seconds to resolve(?) the address http://bridged for a web browser. Additionally I have just installed samba service and noticed similar problem, so it is not specific to browser & http. Initial access for samba shares also takes long time.

• How to use multiple variables in time calculator c#

  - by Peter O'Dwyer

  I am building a video time calculator and need to use the number of frames instead of milliseconds. e.g 25FPS HH:MM:SS:FR 00:00:10:24 <-- Last frame of 10 seconds 00:00:11:00 <-- First frame of 11 seconds My problem is that if the start frames are lower than my end frames it can't calculate the time. 00:00:10:05 <-- Start 01:00:10:10 <-- End 00:59:59:05 <-- Answer which I can't get!! HERE'S MY CODE string Startdate = Dur_txtStart.Text; string Enddate = Dur_txtEnd.Text; string Startdate1 = Startdate.Substring(0, 8); int Startframe1 = Convert.ToInt32(Startdate.Substring(9, 2)); string Startdate2 = Enddate.Substring(0, 8); int Startframe2= Convert.ToInt32(Enddate.Substring(9, 2)); TimeSpan diff = DateTime.Parse(Startdate2).Subtract(DateTime.Parse(Startdate1)); int frameDiff = Startframe2 - Startframe1; int Hour = Convert.ToInt32(diff.Hours); int Min = Convert.ToInt32(diff.Minutes); int Sec = Convert.ToInt32(diff.Seconds); if (frameDiff < 0 && Sec > 0) { Sec -= 1; string frameDiffBuild = string.Format("{0}:{1}:{2}:{3}",Hour.ToString("D2"), Min.ToString("D2"), Sec.ToString("D2"), (Convert.ToInt32(Dur_txtFPS.Text + frameDiff)).ToString("D2")); Dur_txtOutTime.Text = frameDiffBuild; } else { string frameDiffBuild = string.Format("{0}:{1}:{2}:{3}",Hour.ToString("D2"), Min.ToString("D2"), Sec.ToString("D2"), frameDiff.ToString("D2")); Dur_txtOutTime.Text = frameDiffBuild; } Hope you can help guys my head is mashed!

• Windows 7 hangs after going into sleep a second time

  - by Brian Stephenson

  I've searched everywhere around Google and can't figure out why this is happening so I decide to ask here to see if anyone has a problem like this. Like it says in the title, whenever I sleep ONCE I'm able to wake the system, but going back to sleep again AFTER waking up for the first time results in it hanging on no input and no output, with the fan spinning as fast as possible and alot of heat being spewed out by the fan as well. I've tried various things like setting all USB Hub Root's to not get switched off for power saving, disabling USB selective suspend, disabling PCI-e link state power management, and even unplugging ALL USB devices and it wont wake up after the second attempt. And I've even waited up to a full hour of the CPU fan spinning loudly and it's still stuck trying to wake up. The only USB devices I use are a Microsoft USB Comfort Curve Keyboard 2000 (IntelliType Pro) and a generic HID compliant mouse from Creative model number OMC90S "CREATIVE MOUSE OPTICAL LITE". My other devices like external drives and controllers are unplugged when I'm not using them as having too many USB devices plugged in at a time causes a deadlock on almost all of the ports I have. Here's my system specifications (Most of these are from CPU-Z): Brand: Gateway DX4300-19 Mainboard: Gateway RS780 Chipset: AMD 780G Rev 00 Southbridge: AMD SB700 Rev 00 LPCIO: ITE IT8718 BIOS: American Megatrends Inc. ver P01-A4 09/15/2009 CPU: AMD Phenom II X4 810 at 2.60 GHz RAM: 8.0 GB DDR2 Dual Channel Ganged Mode at 400 MHz GPU: ATI Radeon HD3200 Graphics Intergrated - RS780 OS: Windows 7 Home Premium x64 OEM (Acer Group) HDD: WDC WD10EADS-22M2B0 1.0 TB (Western Digital Green Caviar) My BIOS has absolutely no control over how I setup the sleep mode to be either S1 or S3. So I can't check these settings or even change them. Hybrid sleep is also disabled, I can successfully go into hibernation and wake from hibernation but this is painfully slow due to a harddrive problem I'm having with this "Green Drive". (Hibernation takes over ~3 minutes to complete) Any help would be appreciated, thanks.

• Unable to connect to server after a certain amount of time

  - by Troy

  I am a business FIOS subscriber with 5 static IPs. I have the following network setup: Verizon provided ONT Dlink switch Dell server running Ubuntu 12.04 with iptables enabled and a static IP address. The makes/models of hardware are: FIOS ONT Alcatel-Lucent I-211M-H ONT D-Link D-Link Web Smart Switch DES-1228P Server Dell Optiplex 755 (Ubuntu 12.04 Server) I have iptables running on the server with http, https and ssh ports open. I can connect to a website on the server from an external computer, but after a certain amount of time (mins to hours), I can no longer connect. All I have to do to re-enable connectivity is connect to the server via SSH from a computer INSIDE the network. I don't have to actually login, I just have to establish a connection. I can then access the website externally again. I did some googling and it seems some of verizon's equipment had an ARP bug where the ARP entries would expire after a certain time period, but those issues all seem to be from back in 2009 - 2010. I know the switch has an 'auto learning Mac address' feature, but I'm not sure if that could be the problem or not. Does anyone have any ideas or advice on how I can troubleshoot this? Thanks!

• Hearing a clicking noise from soundcard all the time

  - by Mehrdad

  I have installed Fedora 17 on my laptop. A few days ago I updated my fedora (but not upgraded). I shut down my computer and since the next time I turned it on I am hearing a clicking noise all the time from speakers. Even when I plug my headphones in I hear the noise through the headphone. I surfed over the internet and found the following shell commands: su -c 'echo "options snd_hda_intel power_save=0" /etc/modprobe.d/snd_hda_intel.conf' su -c 'echo 0 /sys/module/snd_hda_intel/parameters/power_save' I tried them but they didn't work. Here is the part of "lspci" command related to my sound-card: 00:1b.0 Audio device: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) High Definition Audio Controller (rev 03) I have to add that my sound-card is working and I can play some audio file, I mean I can hear the voice and noise simultaneously. But everything is OK in windows xp which is also installed on my laptop. Could it be related to the sound-card driver? If so, how can I revert it to the previous version?

• Snow Leopard takes a long time to connect to Windows/Samba server

  - by hood

  We run a very heterogeneous network here: There is some XP, Vista, 7, Leopard, Snow Leopard clients, and Windows 2003 (one remaining legacy app), 2008, and Linux servers. The main file server runs Ubuntu Linux and has been added to the Windows Domain and has been used for many years; SBS 2008 is the PDC (the 2003 and 2008 are on the domain also). In Leopard there were no problems at all authenticating to the file servers. We've upgraded one of the Leopard iMacs to Snow Leopard, though the same problem occurs in a new MBP which came with the newer OS as well as a clean install on another iMac. It does not matter whether connected through wired or wireless. In the Finder when clicking on the server - whether on first boot or after it is connected - it will display "Connecting..." for up to a few minutes before either generally working (if username/password in keychain) or displaying "Connection Failed" - at which time clicking "Connect As" and typing in the username/password will take some more time and eventually work. Sometimes it will display "Connecting..." indefinitely. (I've left it as long as 15 minutes before trying something else) Accessing shares on the the 2003 and SBS servers have the problem (so I don't think it's a Samba server issue). The Server 2008 Standard is connecting instantly at the moment. Accessing the share through an alias/stacks doesn't have this problem. Leopard and Windows clients still have no problem. I've searched Google but hasn't yielded any working result. How do I get rid of this delay?

• Perfmon % Processor Time vs. task manager's CPU usage

  - by nat

  I'm new to using Perfmon and performance monitoring in general (so go easy on me please ;) I know that Perfmon doesn't have anything exactly like Task Manager's CPU usage display, but I'm trying to figure out how to monitor user's CPU usage via Perfmon in a similar way, and trying to understand the measurements (or how to convert the numbers to get a similar understanding) For example, if in Task Manager, a particular user is consistently using more than 5% CPU, I would want to contact the user about it. I learn best by example, so here is exactly what I'm trying to do, with a specific example: This is for a 32-bit Dual Quad Core Windows 2003 web server (8 CPUs), there are many web sites on the server, each running within their own application pool/worker process ID. Through other research here I learned of a registry change that I made so that the PID shows up with the w3wp process so I can easily identify the site later by cross-referencing it. I set up a counter with the following settings: Process -> % Processor Time -> all instances Here is an example. Say I'm interested in "black line" user in this graph below, as his process is spiking quite high compared to all the other users: (I wasn't allowed to post the image as I'm a new user on this site.. I've uploaded the image to:) http://i35.tinypic.com/106yn8k.jpg So... using this as an example, I see that they have an AVERAGE % PROCESSOR TIME of 23.264 , and have spiked as high as 103.124 So what exactly does this 23.264 number mean to me? Is it similar to an average of Task Manager's CPU reading for this user? Or, since this server has 8 CPUs, should I divide this number by 8? (23.264/8 = 2.9% AVERAGE CPU LOAD?) Thanks in advance.

• Need help with android.os.Build.VERSION.SDK_INT and SharedPreferences

  - by Fenderf4i

  I have a main activity where I call VersionSettings vs = new VersionSettings(this); if (vs.firstRun2()) vs.versionCheckbox(); What I'm trying to do is set a checkbox (checkboxVideoType) to an unchecked state if the Android version is 1.6-2.1 I only want to do this the very first time the app is ever run, it never needs to run again. I think I'm running into the problem when the main activity calls versionCheckbox(), I get a force close if it attempts to run the code inside that is going to set the checkbox to false. I'm very new to programming and would really appreciate some help with this. I think I'm close, but need a push. Thanks in advance!

• Building a DataTable in C# with one column at a time

  - by Awaken

  I am trying to build a Retirement Calculator as a chance to make something useful and learn C# better. Currently, I am trying to build a DataTable with a dynamic amount of rows/columns. For context, I ask the user for some inputs regarding salary, % of salary being invested, and expected ROI. I have some other stuff too, but it isn't really part of the issue I am having. Because the number of columns I need for the DataTable is unknown until the formula is run (while+for loop completes), I am having trouble doing things as DataColumns. Hopefully the code below will help. I am really trying to build the table one column at a time. I realize I could reverse it to build it one row at a time because the Years before retirement (yearsRetire) is known, but I would prefer not to and I want to learn more. Sorry for the indentation and commenting. I tried to leave some of my commented coding attempts in there. Thanks for any help. public double calcROI() { double testROI = 0.00; double tempRetireAmount = 0; double adjustRetire = goalAmount * (1 + (Math.Pow(inflation,yearsRetire))); // Loop through ROI values until the calculated retire amount with the test ROI // is greater than the target amount adjusted for inflation while (tempRetireAmount < adjustRetire) { //Increment ROI by 1% per while iteration testROI += .01; //Make a new Column to hold the values for ROI for this while iteration //dtMain.Columns.Add(Convert.ToString(testROI)); //DataColumn tempdc = new DataColumn(Convert.ToString(testROI)); //Loop through the number of years entered by user and see the amount //at Retirement with current ROI for (int i = 0; i < yearsRetire; i++) { //Main formula to calculate amount after i years tempRetireAmount = (tempRetireAmount + salary*savingsPct) * (1 + testROI); // Add value for this year/ROI to table/column //DataRow dr = .NewRow(); //dr tempRetireAmount; //tempdc[i] = tempRetireAmount; } //Need to add column of data to my Main DataTable //dtMain.Rows.Add(dr); //dtMain.Columns.Add(tempdc); } return testROI; }

• Openswan + xl2tpd connections time out after a while

  - by Halfgaar

  I have a non-NATed Openswan+xl2tpd server (Ubuntu 12.04), to which I connect with a Windows 8 behind NAT. The client loses its connection after a while of doing nothing (between 30 and 60 minutes, but I didn't time it). The client doesn't have enabled that it should kill inactive connections. Nor does it ever go into sleep mode. I also tried setting the kill-after-time to 24 hours, but that didn't help. The NAT router behind which the client located is Debian Linux, and its router is a Cisco which connects us directly to the data center where the server is. None of our other connections, like SSH, get dropped with inactivity (because of cheap routers). I did however try turning on the keepalives in /etc/ipsec.conf: config setup (...snip...) nat_traversal=yes force_keepalive=yes keep_alive=10 but that didn't help. As you can see in the config later, dead peer detection's action is clear. That would be a first suggestion to fix, but I need clear, because people will be connecting from everwhere but the kitchen sink. Besides, as I said, in the test setup I have now, I can't see any device killing its connection. (edit: 'restart' also has the same effect) These are of one time it happened: Jul 18 16:18:06 host xl2tpd[1918]: Maximum retries exceeded for tunnel 49070. Closing.

• HTTP downloads stop after some time, resuming is not possible

  - by cdauth

  When I try to download a file via HTTP, the downloads sometimes stop after around 30 MB. The download rates goes down to 0 B/s and no data keeps coming. When I stop the download and resume again, the download still hangs. But when I redownload it from byte 0 again, everything works fine up to 30 MB when it stops again. Sometimes, after some hours, it just works again without problems. The position in the file when the download stops is variable, but most of the time it is around 30–35 MB. As a download manager I use wget. The same behaviour happens though using curl and other download managers. The error occurs independently of the server I download from. I have also observed this error on other Linux computers in my network. All computers on my network run Gentoo Linux on x86. All internet connections on my network go through a server on my network which runs a transparent Squid proxy on port 80. That server is connected to a router, which is a Speedport W 700V by Deutsche Telekom AG. That router is connected to the internet using ADSL, with 448 kbit/s down speed and 96 kbit/s up speed. I am almost sure that my transparent proxy is not the problem. I turned that off without resolving the issue. I also connected to the router directly via WLAN without resolving the issue. I also tried to download over another port via HTTP. Furthermore, I tried to download the file using IPv6 with a gateway6 tunnel from my computer, which resulted in exactly the same problem. Now the strange thing is that everything works fine using FTP and HTTPS (also with wget on the same computer). Even more strange: when I resume the download that hanged over HTTP using FTP or HTTPS, download a few bytes that way, stop wget and then resume again using HTTP, it loads data again! But after a few MB, it may stop again. Unfortunately, files downloaded that way are always broken (the MD5 sum is not correct), so at some point, there must have been bogus data. I tried searching for HTML error messages in the downloaded file, but grep -i html does not find anything. (I cannot think of a way to search for GZIP-compressed HTML error messages in the file, so I did not try that.) I tried using strace on wget when it failed to resume a download, you can find the entire output on pastebin. The important lines are repeated every second: clock_gettime(CLOCK_MONOTONIC, {326102, 62176435}) = 0 ) = 1 write(2, "78% [++++++++++++++++++++++++++++"..., 19578% [+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ ] 110,683,685 --.-K/s ) = 195 select(4, [3], NULL, NULL, {0, 949999}) = 0 (Timeout) I have absolutely no idea what could be the reason of this problem. It seems like whatever causes the issue speaks HTTP. It seems to speak HTTP that intelligently that it even regognises it in an IPv6-over-IPv4 tunnel. But what could that be and why does it only happen sometimes? The other possibility would be that there is a problem on my computer that is the same on other Gentoo Linux computers as well. Has anyone ever had such a problem? What could be the reason and where do I have to continue investigating to find out more about the issue? Update: I have just run into the problem again and tried to resume the download over the router’s WLAN, and this time it worked. Maybe I did something wrong during my last tests with the WLAN. Now maybe my transparent proxy server is in fact the problem. It is a very basic Squid proxy server that does not cache anything. Maybe the fact is interesting that a second Squid proxy runs on the same computer on another port. Update: A download hung again and this time I turned off all firewall settings and stopped all proxy servers. I failed to resume the download from my network server, which is directly connected to the router. So my proxy server definitely is not the cause the problem. I will try to upgrade the firmware of my router now, although I do not have admin access to it. I will see what I can do.

• TFS 2010 build config transform problem

  - by Zdenek

  Hi all, I'm facing quite a problem while setting up automated TFS Builds. Basically I created new configuration called Tests, added transform config, defined different connection strings for the Database. Then defined TFS build, building whole solution with MSBuild arguments /p:DeployOnBuild=True /p:Configuration=Tests. The problem is that in the drop location (Build_PublishedWebsites\Project) I get web.config, web.debug.config, web.release.config and web.tests.config, however I would expect just one transformed web.config. I already checked PDC presentation Web Deployment Painkillers: Microsoft Visual Studio 2010 & MS Deploy but didn't help. Thanks for any answer.

• Stop IIS 7 Application Pool from build script

  - by Andrew Hanson

  How can I stop and then restart an IIS 7 application pool from an MSBuild script running inside TeamCity. I want to deploy our nightly builds to an IIS server for out testers to view. I have tried using appcmd like so: appcmd stop apppool /apppool.name:MYAPP-POOL ... but I have run into elevation issues in Windows 2008 that so far have stopped me from being able to run that command from my TeamCity build process because Windows 2008 requires elevation in order to run appcmd. If I do not stop the application pool before I copy my files to the web server my MSBuild script is unable to copy the files to the server. Has anybody else seen and solved this issue when deploying web sites to IIS from TeamCity?

• xcode build to iphone chooses old invalid provisioning profile

  - by sapatos

  I've just gone through some pain with iphone and xcode upgrades and keychain failures etc and decided to uninstall xcode completely and re-install. This fixed my keychain issues however the project I am working on appears to be linked to an old invalid provisioning profile. I've deleted the profile from "Provisioning Profiles" in organiser, and removed it from Provisioning on the Iphone section of Organiser. However when I build an go with the iphone sdk rather than simulator i get the pop up "codesign wants to sign using key "OldKey" in your keychain". It appears the actual app is associated with the old key and I can't seem to find how to point it to the new valid one. Crazy thing is at some point I managed to get it to work and install but the application crashed and won't open. I've not managed to get it to install again. Any ideas?

• Algorithm: Build a recommendation for movies you might like

  - by Faruz

  I need help designing an algorithm for recommendations on movies. Every user in the system grades movies on a score between 1-100. Tables consist of: Table Movies ID Name Year Rating Runtime Table Con_MoviesToGenres MovieID GenreID Table Con_MovieToUser MovieID UserID Grade I'm trying to build a SELECT query to return 5 most recommended movies for a specific movie. Bearing in mind, I want to integrate in some way, similar genres, highest grades & movie Rating (so you want be recommended an R rated movie for a PG rated movie, unless it's really recommended in every other aspect). Also, if movie matches more than one genre, it will increase its recommendation ratio. Bonus: If a user gives a low grade to a movie - it will lose recommendation ratio.

• Showing all a Gem's build flags

  - by Rob

  This is more a curiosity than necessity question. I've just installed nokogiri again with RubyGems and it is saying "WARNING: Nokogiri was built against LibXML version 2.7.5, but has dynamically loaded 2.7.6" This is easy enough to fix, but it lead to a more general question: how do I see all the configuration options for a rubygem before installing it? I found the easiest way I know how is to visit the gem folder an run "ruby nokogiri-0.0.0/ext/nokogiri/extconf.rb -h" and that shows me it, but there has to be an easier way, right? I was expecting some kind of "sudo gem install nokogiri -- --help" command that would show the build flags. I've searched around a bit but didn't see anything, anybody know how to do this before I go digging into RG's source :)?
