  • Why is connecting to external FTP sites slow on virtual 2008 R2 and not on host?

    - by subkamran
    I have Windows Server 2008 R2 installed as a virtual guest in my Windows 7 host via VirtualBox 4.0. I did this to move my development activity to a controlled environment that doesn't affect my host OS when I don't want to develop. The problem I have is that when I try to connect to my shared hosting FTP, it's slow as hell on the virtual OS but perfectly fast on the host. I tried: Disabling Windows Firewall Trying several different FTP clients Anyone else have this issue?

  • CPU running at full capacity when boot to DOS?

    - by Kevin H
    Does the CPU is run at 100% or near full capacity when the computer is booted into MS-DOS? Will the CPU temperature become higher even though we are not running any program in DOS mode? In Windows, we can see the CPU usage in % of utilization in Task Manager. From what I heard, CPU is running at near 100% capacity in DOS OS or in the BIOS MAIN screen. Is this caused by lack of CPU optimization in DOS OS?

  • Does anyone know why my WiFi connection suddenly keeps disconnecting, and will not re-connect withou

    - by Xavierjazz
    Does anyone know why my WiFi connection suddenly keeps disconnecting, and will not re-connect without a boot? I looked at other questions, but the OS is different and its not regular. Also the only answer there is not useful. I have had this connection for about 2 weeks with no problems, but suddenly, yesterday, it happened a few times and today it has happened at least 8 times so far. ISP: Bell Sympatico OS: XP SP3 Thanks all.

  • Virtual Box for everyday use?

    - by Mark
    I was just thinking about how nice virtual machines are...and how even "rebooting" is less painful, because at the very least, you don't have to wait for your physical computer to turn off and on with all the mobo shannanigans at the start... so, what if I ran everything in a virtual machine? Then I wouldn't really need a primary OS, I just need something than can run VirtualBox or what have you. So what's the lightest weight OS I could install, that supports a good virtual machine?

  • Use a RAID Controller without drivers?

    - by cian1500ww
    Ordered an Adaptec 1420SA RAID card for my Debian Squeeze media server but didn't check to see if it was compatible, turns out it's not because it uses something called hostRAID which requires special drivers that aren't available for Debian. Could I still use the card as an ordinary controller and just use OS software RAID?? I'm not looking for speed, just need to mirror some drives that will be used for storage, the OS will reside on a disk connected to the server's onboard controller so the system won't be booting from any drives on the Adaptec controller.

  • How to use USB Key in Xen 5.6 Environment?

    - by Az
    I am looking for a way to use USB key on a guest OS running on a 5.6 Xen Server environment. The catch is that I need to actually detect in the Guest OS (Win2003 Server) like an actual USB Key. Attaching it as a storage drive doesnt work (It is a key with special attributes that servers as a licensing mechanism). Just wondering if anyone has had a similar need and found a good solution? Thanks, Nate

  • Use ASP.NET 4 Browser Definitions with ASP.NET 3.5

    - by Stephen Walther
    We updated the browser definitions files included with ASP.NET 4 to include information on recent browsers and devices such as Google Chrome and the iPhone. You can use these browser definition files with earlier versions of ASP.NET such as ASP.NET 3.5. The updated browser definition files, and instructions for installing them, can be found here: http://aspnet.codeplex.com/releases/view/41420 The changes in the browser definition files can cause backwards compatibility issues when you upgrade an ASP.NET 3.5 web application to ASP.NET 4. If you encounter compatibility issues, you can install the old browser definition files in your ASP.NET 4 application. The old browser definition files are included in the download file referenced above. What’s New in the ASP.NET 4 Browser Definition Files The complete set of browsers supported by the new ASP.NET 4 browser definition files is represented by the following figure:     If you look carefully at the figure, you’ll notice that we added browser definitions for several types of recent browsers such as Internet Explorer 8, Firefox 3.5, Google Chrome, Opera 10, and Safari 4. Furthermore, notice that we now include browser definitions for several of the most popular mobile devices: BlackBerry, IPhone, IPod, and Windows Mobile (IEMobile). The mobile devices appear in the figure with a purple background color. To improve performance, we removed a whole lot of outdated browser definitions for old cell phones and mobile devices. We also cleaned up the information contained in the browser files. Here are some of the browser features that you can detect: Are you a mobile device? <%=Request.Browser.IsMobileDevice %> Are you an IPhone? <%=Request.Browser.MobileDeviceModel == "IPhone" %> What version of JavaScript do you support? <%=Request.Browser["javascriptversion"] %> What layout engine do you use? <%=Request.Browser["layoutEngine"] %>   Here’s what you would get if you displayed the value of these properties using Internet Explorer 8: Here’s what you get when you use Google Chrome: Testing Browser Settings When working with browser definition files, it is useful to have some way to test the capability information returned when you request a page with different browsers. You can use the following method to return the HttpBrowserCapabilities the corresponds to a particular user agent string and set of browser headers: public HttpBrowserCapabilities GetBrowserCapabilities(string userAgent, NameValueCollection headers) { HttpBrowserCapabilities browserCaps = new HttpBrowserCapabilities(); Hashtable hashtable = new Hashtable(180, StringComparer.OrdinalIgnoreCase); hashtable[string.Empty] = userAgent; // The actual method uses client target browserCaps.Capabilities = hashtable; var capsFactory = new System.Web.Configuration.BrowserCapabilitiesFactory(); capsFactory.ConfigureBrowserCapabilities(headers, browserCaps); capsFactory.ConfigureCustomCapabilities(headers, browserCaps); return browserCaps; } At the end of this blog entry, there is a link to download a simple Visual Studio 2008 project – named Browser Definition Test -- that uses this method to display capability information for arbitrary user agent strings. For example, if you enter the user agent string for an iPhone then you get the results in the following figure: The Browser Definition Test application enables you to submit a user-agent string and display a table of browser capabilities information. The browser definition files contain sample user-agent strings for each browser definition. I got the iPhone user-agent string from the comments in the iphone.browser file. Enumerating Browser Definitions Someone asked in the comments whether or not there is a way to enumerate all of the browser definitions. You can do this if you ware willing to use a little reflection and read a private property. The browser definition files in the config\browsers folder get parsed into a class named BrowserCapabilitesFactory. After you run the aspnet_regbrowsers tool, you can see the source for this class in the config\browser folder by opening a file named BrowserCapsFactory.cs. The BrowserCapabilitiesFactoryBase class has a protected property named BrowserElements that represents a Hashtable of all of the browser definitions. Here's how you can read this protected property and display the ID for all of the browser definitions: var propInfo = typeof(BrowserCapabilitiesFactory).GetProperty("BrowserElements", BindingFlags.NonPublic | BindingFlags.Instance); Hashtable browserDefinitions = (Hashtable)propInfo.GetValue(new BrowserCapabilitiesFactory(), null); foreach (var key in browserDefinitions.Keys) { Response.Write("" + key); } If you run this code using Visual Studio 2008 then you get the following results: You get a huge number of outdated browsers and devices. In all, 449 browser definitions are listed. If you run this code using Visual Studio 2010 then you get the following results: In the case of Visual Studio 2010, all the old browsers and devices have been removed and you get only 19 browser definitions. Conclusion The updated browser definition files included in ASP.NET 4 provide more accurate information for recent browsers and devices. If you would like to test the new browser definitions with different user-agent strings then I recommend that you download the Browser Definition Test project: Browser Definition Test Project

  • Python - Calling a non python program from python?

    - by Seafoid
    Hi, I am currently struggling to call a non python program from a python script. I have a ~1000 files that when passed through this C++ program will generate ~1000 outputs. Each output file must have a distinct name. The command I wish to run is of the form: program_name -input -output -o1 -o2 -o3 To date I have tried: import os cwd = os.getcwd() files = os.listdir(cwd) required_files = [] for i in file: if i.endswith('.ttp'): required_files.append(i) So, I have an array of the neccesary files. My problem - how do I iterate over the array and for each entry, pass it to the above command (program_name) as an argument and specify a unique output id for each file? Much appreciated, S :-)

  • EXC_BAD_INSTRUCTION (SIGILL) at random during use of app. Bug in AppKit?

    - by Ger Teunis
    I'm currently testing a new version of an app of mine on OSX 10.5 An user reported some weird crashes during use of the application, sadly not reproducible by me. At first sight it seems to happen randomly, once he had the crash while opening an NSOpenPanel and once during focusing an NSTextField and once during NSView switch in a parent view. If you have any idea which area I should look at it would be greatly appreciated! I'm completely lost here.

  • FireFox 6 Super Slow? Cache Settings Corruption

    - by Rick Strahl
    For those of you that follow me on Twitter, you've probably seen some of my tweets regarding major performance problems I've seen with the install of FireFox 6.0. FireFox 6.0 was released a couple of weeks ago and is treated as a 'force feed' update for FireFox 5.0. I'm not sure what the deal is with this braindead versioning that Mozilla is doing with major version releases coming out, what now every other month? Seriously that's retarded especially given the limited number of new features these releases bring, and the upgrade pain for plug-ins that the major version release causes. Anyway, after the FireFox updater bugged me long enough I finally gave in last week and updated to FireFox 6. Immediately after install I noticed terrible performance. Everything was running at a snail's pace with Web pages loading slowly and most content actually slowly 'painting' the page. A typical sign of content downloading slowly. However these are pages that should be mostly cached on my system and even repeated accesses ran just as slow. Just for a reality check I ran the same sites in Chrome (blazing fast) and IE (fast enough :-)) but FireFox - dog on a stick. Why so slow Boss? While complaining lots of people recommended to ditch FireFox - use Chrome, yada yada yada. Yeah, Chrome is fast and getting better but I have a number of plug-ins that I use in FF that I can't easily give up. So I suffered and started looking around more closely at what was happening. The first thing I noticed when accessing pages was that I continually saw accesses to the Google CDN downloading jQuery and jQuery UI. UI especially is pretty heavy in size and currently I'm in a location with a fairly slow IP connection where large files are a bit of an issue. However, seeing the CDN urls pop up repeatedly raised a flag with me. That stuff should be caching and it looked like each and every hit was reloading these scripts and various images over and over again. Fired up FireBug and sure enough I saw something like this on a repeated hit to my blog: Those two highlights are jquery and the main CSS file for the site and both are being loaded fully and taking a while to load. However, since this page had been loaded before, these items should be cached and show 304 requests instead of the full HTTP requests returning 200 result codes. In short it looked like FireFox was not caching ANY content at all and constantly reloading all page resources. No wonder things were running dog slow. Once I realized what the problem was I took a look in the about:config settings and lo and behold a bunch of the cache settings were set to not cache: In my case ALL the main cache flags were set to false for some reason that I can't figure out.  It appears that after the FireFox 6 update these flags somehow mysteriously changed and performance took a nose dive. Switching the .enable flags back to true and resetting all the cache settings tote default reverted performance back to the way it's supposed to be: reasonably fast and snappy as soon as content is cached and accessed again  from cache. I try not to muck with the about:config settings much (other than turning off the IPV6 option) but when there are problems access to these features can be really nice. However, I treat this as a last resort so it took me quite some time before I started looking through ALL the settings. This takes a while, not knowing what I was looking for exactly. If Web load performance is slow it's a good idea to check the cache settings. I have no idea what hosed these settings for me - I certainly didn't explicitly set them in about:config and while in FireFox's Options dialog I didn't see any option that would affect global caching like this, so this remains a mystery to me. Anyway, I hope that this is helpful to some, in case some of you end up running into a similar issue.© Rick Strahl, West Wind Technologies, 2005-2011Posted in FireFox   Tweet (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

  • PycURL RESUME_FROM

    I can't seem to get the RESUME_FROM option to work. Here's some example code that I have been testing with: import os import pycurl import sys def progress(total, existing, upload_t, upload_d): try: frac = float(existing)/float(total) except: frac = 0 sys.stdout.write("\r%s %3i%%" % ("file", frac*100) ) url = "http://launchpad.net/keryx/stable/0.92/+download/keryx_0.92.4.tar.gz" filename = url.split("/")[-1].strip() def test(debug_type, debug_msg): print "debug(%d): %s" % (debug_type, debug_msg) c = pycurl.Curl() c.setopt(pycurl.URL, url) c.setopt(pycurl.FOLLOWLOCATION, 1) c.setopt(pycurl.MAXREDIRS, 5) # Setup writing if os.path.exists(filename): f = open(filename, "ab") c.setopt(pycurl.RESUME_FROM, os.path.getsize(filename)) else: f = open(filename, "wb") c.setopt(pycurl.WRITEDATA, f) #c.setopt(pycurl.VERBOSE, 1) c.setopt(pycurl.DEBUGFUNCTION, test) c.setopt(pycurl.NOPROGRESS, 0) c.setopt(pycurl.PROGRESSFUNCTION, progress) c.perform()
