• CPAN mirroring problem in cpan::mirrror

  - by user304122

  I am on a corporate PC that forces mcshield on everything that moves. I get blocked when trying to mirror on :- . . . . . . authors/id/J/JV/JV/EekBoek-2.00.01.tar.gz ... updated authors/id/J/JV/JV/CHECKSUMS ... updated Could not stat tmpfile '/cygdrive/t/cpan_mirror/authors/id/J/JW/JWIED/Mail-IspMailGate-1.1013.tar.gz-4712': No such file or directory at /usr/lib/perl5/site_perl/5.10/LWP/UserAgent.pm line 851. authors/id/J/JW/JWIED/Mail-IspMailGate-1.1013.tar.gz At this point, I get the Virus scanner mcshield sticking its Awr in. To maintain my mirror I execute:- #!/usr/bin/perl CPAN::Mini-update_mirror( remote = "http://mirror.eunet.fi/CPAN", local = "/cygdrive/t/cpan_mirror/", trace = 1, errors = 1, module_filters = [ qr/kjkjhkjhkjkj/i, qr/clamav/i, qr/ispmailgate/i, qr/IspMailGate/, qr/Mail-IspMailGate/, qr/mail-ispmailgate/i, ], path_filters = [ qr/ZZYYZZ/, #qr/WIED/, #qr/RJBS/, ] ); It skips OK if I enable the path_filter WIED. Just cannot get it to skip the module failing module to complete other WIED modules. Any ideas ?? .

• Why is software quality so problematic?

  - by Yuval A

  Even when viewing the subject in the most objective way possible, it is clear that software, as a product, generally suffers from low quality. Take for example a house built from scratch. Usually, the house will function as it is supposed to. It will stand for many years to come, the roof will support heavy weather conditions, the doors and the windows will do their job, the foundations will not collapse even when the house is fully populated. Sure, minor problemsdo occur, like a leaking faucet or a bad paint job, but these are not critical. Software, on the other hand is much more susceptible to suffer from bad quality: unexpected crashes, erroneous behavior, miscellaneous bugs, etc. Sure, there are many software projects and products which show high quality and are very reliable. But lots of software products do not fall in this category. Take into consideration paradigms like TDD which its popularity is on the rise in the past few years. Why is this? Why do people have to fear that their software will not work or crash? (Do you walk into a house fearing its foundations will collapse?) Why is software - subjectively - so full of bugs? Possible reasons: Modern software engineering exists for only a few decades, a small time period compared to other forms of engineering/production. Software is very complicated with layers upon layers of complexity, integrating them all is not trivial. Software development is relatively easy to start with, anyone can write a simple program on his PC, which leads to amateur software leaking into the market. Tight budgets and timeframes do not allow complete and high quality development and extensive testing. How do you explain this issue, and do you see software quality advancing in the near future?

• How to Compile Mod_Python 3.3.1 for Python 2.6 and Apache 2.2 on Windows?

  - by John

  I have no experience compiling code other than using Visual Studio's Build command. I am hoping we can create a step by step guide for compiling mod_python on windows. Please be as descriptive as possible. This is what I've done so far: Download and install python 2.6.2 Download and install apache 2.2.11 Download the most recent source code for mod_python from svn From here I'm lost to what the next step is. I've downloaded Microsoft Visual C++ 2008 Express Edition. As mentioned by Hao I've already tried the tutorial mentioned in that link. Here is the error messages I'm receiving with that tutorial.

• .NET assembly cache / ngen / jit image warm-up and cool-down behavior

  - by Mike Jiang

  Hi, I have an Input Method (IME) program built with C#.NET 2.0 DLL through C++/CLI. Since an IME is always attaching to another application, the C#.NET DLL seems not able to avoid image address rebasing. Although I have applied ngen to create a native image of that C#.NET 2.0 DLL and installed it into Global Assembly Cache, it didn't improved much, approximately 12 sec. down to 9 sec. on a slow PIII level PC. Therefore I uses a small application, which loads all the components referenced by the C#.NET DLL at the boot up time, to "warm up" the native image of that DLL. It works fine to speed up the loading time to 0.5 sec. However, it only worked for a while. About 30 min. later, it seems to "cool down" again. Is there any way to control the behavior of GAC or native image to be always "hot"? Is this exactly a image address rebasing problem? Thank you for your precious time. Sincerely, Mike

• Powershell: Select-Object with additional calculated difference value

  - by David.Chu.ca

  Let me explain my question. I have a daily report about one PC's free space as in text file (sp.txt) like: DateTime FreeSpace(MB) ----- ------------- 03/01/2010 100.43 DateTime FreeSpace(MB) ----- ------------- 03/02/2010 98.31 .... Then I need to use this file as input to generate a report with difference of free space between dates: DateTime FreeSpace(MB) Change ----- ------------- ------ 03/01/2010 100.43 03/02/2010 98.31 2.12 .... Here are some codes I have to get above result without the additional "Change" calculation: Get-Content "C:\report\sp.txt" ` | where {$_.trim().length -gt 0 -and -not ($_ -like "Date*") -and -not ($_ -like "---*")} ` | Select-Object @{Name='DateTime'; expression={[DateTime]::Parse($_.SubString(0, 10).Trim())}}, ` @{Name='FreeSpace(MB)'; expression={$_.SubString(12, 12).Trim()}}, ` | Sort-Object DateTime ` | Select-Object DateTime, 'FreeSpace(MB)' |ft -AutoSize # how to add additional column Change to this Select-Object? My understanding is that Select-Object will return a collection of objects. Here I create this collection from an input text file(parse each line into parts: datetime and freespace(MB)). In order to calculate the difference between dates, I guess that I need to add additional calculated value to the result of the last Select-Object, or pipe the result to another Select-Object with the calculation as additional property or column. In order to do it, I need to get the previous row's FreeSpace value. Not sure if it is possible and how?

• what can be causes of http server crash?

  - by mithunmo

  Hello , I am using WAMP server on Windows XP. - Apache 2.2.11 - MySQL 5.1.36 (INNODB engine) - PHP 5.3.0 I observe that my WAMP server crashes in the following scenarios 1) IF I use a Low end PC ( low processor speed and low RAM) 2) After making some changes to httpd.conf file .For eg changing the Allow from IP address . But here it crashes only once and then it starts to work fine. 3) Random crashes CRASH LOG szAppName : httpd.exe szAppVer : 2.2.11.0 szModName : php5ts.dll szModVer : 5.3.0.0 offset : 0000c309 C:\DOCUME~1\blrcom\LOCALS~1\Temp\WERc677.dir00\httpd.exe.mdmp C:\DOCUME~1\blrcom\LOCALS~1\Temp\WERc677.dir00\appcompat.txt My questions 1) Does high CPU utilization/LOW RAM can also cause the HTTP server to crash ? 2) excessive file reading as in every 10 seconds ? 3) unlimited script execution time . I have set the maximum execution time in php script to 0 as my script has to execute for sometimes 2-3 days. Is there any way to avoid this ? 4) Access to Database ? Should we use lock before reading and writing Can these be the reasons for random wamp server crashes ? OR is is some other programming error ? Please guide me . Regards, Mithun

• Building Cross Platform app - recommendation

  - by Ben

  Hi, I need to build a fairly simple app but it needs to work on both PC and Mac. It also needs to be redistributable on a disc or usb drive as a standalone desktop app. Initially I thought AIR would be perfect for this (it ticks all the API requirements), but the difficulty is making it distributable, as the app would require the AIR runtime to be installed to run. I came across Shu Player as an option as it seems to be able to package the AIR runtime with the app and do a (silent?) install. However this seems to break the T&C from Adobe (as outlined here) so I'm not sure about the legality. Another option could be Zinc but I haven't tested it so I'm not sure how well it'll fit the bill. What would you recommend or suggest I check out? Any suggestion much appreciated EDIT: There's a few more discussions on mono usage (though no real conclusion): Here and Here EDIT2: Titanium could also fit the bill maybe, will check it out. Any more comments from anyone? Ben

• Server port 16080 problem: webserver adds the port number 16080 in the URL

  Hello everybody. On my wordpress website one little thing doesn't work. Sometimes the Webserver adds the port number 16080 in the URL, which leads to an error (network timeout). Wrong: http://www.example.com:16080/about-us/weekly-program/?month=may&yr=2010 Correct: http://www.example.com/about-us/weekly-program/?month=may&yr=2010 Has someone a "Server port 16080 problem fix"? Is it possible, that I need to add a ServerName directive to the config file to tell the domain name of the server? Cheers Juri !!!update!!!

• Using a Visual Sourcesafe 2005 database with VB6 still launches VSS 6.0d

  - by John Galt

  I know all versions of VSS have many horror stories and I feel I will escape to a better source control mechanism someday but in the short term I am just trying to do a little cleanup and would like your advice on this issue: Objective - consolidate old VB6 source code in a "new" VSS 2005 database (currently all these old projects are checked in to an "old" VSS 6.0d database); eventually, eliminate the "old" VSS. Progress so far - The new VSS 2005 database now contains a mixture of projects. Some are using Visual Studio 2008, some use Vstudio 2005, and the more recently added ones are the above mentioned VB6 projects. Individually all these projects and "solutions" come up OK, I can check in - check out, launch SourceSafe, view differences, etc. But all the VB6 projects now in a VSS 2005 database launch VSS 6.0d when asked, rather than VSS 2005. Is this normal and just something to cope with until I get to some better nonVSS approach? Or can VB6 be re-configured someway to launch VSS 2005 when I click Tools-SourceSafe-Run SourceSafe? I seem to recall VSS 6.0d got "integrated" into VB6 by way of the "Add-In Manager". At this point, the development PC with VB6 installed has both VSS 2005 and VSS 6.0d clients installed.

• C# File IO with Streams - Best Memory Buffer Size

  - by AJ

  Hi, I am writing a small IO library to assist with a larger (hobby) project. A part of this library performs various functions on a file, which is read / written via the FileStream object. On each StreamReader.Read(...) pass, I fire off an event which will be used in the main app to display progress information. The processing that goes on in the loop is vaired, but is not too time consuming (it could just be a simple file copy, for example, or may involve encryption...). My main question is: What is the best memory buffer size to use? Thinking about physical disk layouts, I could pick 2k, which would cover a CD sector size and is a nice multiple of a 512 byte hard disk sector. Higher up the abstraction tree, you could go for a larger buffer which could read an entire FAT cluster at a time. I realise with today's PC's, I could go for a more memory hungry option (a couple of MiB, for example), but then I increase the time between UI updates and the user perceives a less responsive app. As an aside, I'm eventually hoping to provide a similar interface to files hosted on FTP / HTTP servers (over a local network / fastish DSL). What would be the best memory buffer size for those (again, a "best-case" tradeoff between perceived responsiveness vs. performance). Thanks in advance for any ideas, Adam

Here's what it's coming out as: The correct blocks above the non-inline blocks are from a table with the same exact widths as the ones I'm using on the Divs. There isn't any CSS adding pixels to them, I don't think. I need to line these up, and I can't figure out where my problem is here. Any help would be appreciated.

• Opened SerialPort crashes C# application

  - by Stefan Teitge

  The computer is connected to measuring device via a physical COM1. I have simple form where I open a serial port, tell the device that I'm alive and occasionally the device sends data. (every some minutes) Thread _readThread = new Thread(Read); SerialPort _serialPort = new SerialPort("COM1", 9600); _serialPort.Parity = Parity.None; _serialPort.DataBits = 8; _serialPort.StopBits = StopBits.One; _serialPort.Handshake = Handshake.None; _serialPort.DtrEnable = true; _serialPort.Open(); _readThread.Start(); _serialPort.Write("#listening"); The read function (which works): public void Read() { string message = _serialPort.ReadLine(); } After approximately one minute the application crashes (even while debugging). It reports an ObjectDisposedException (for the underlying stream?). The message tells that the SafeHandle was closed. Stack strace is below: at Microsoft.Win32.UnsafeNativeMethods.GetOverlappedResult(SafeFileHandle hFile, NativeOverlapped lpOverlapped, Int32& lpNumberOfBytesTransferred, Boolean bWait) at System.IO.Ports.SerialStream.EventLoopRunner.WaitForCommEvent() at System.Threading.ThreadHelper.ThreadStart_Context(Object state) at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state) at System.Threading.ThreadHelper.ThreadStart()* Any ideas? The problem is reported widely but usually involve the device beeing physically detached from the PC.

• WCF RIA Silverlight deployment issues

  - by Handleman

  It seems the world is awash with people having problems deploying RIA WCF services, and now I'm one too. I've already tried a bunch of things, but to no avail. I need WCF RIA to support a Silverlight 3 application I've built. The short story is, using the new WCF RIA services (Nov 09?) I open VS 2008, create new project (silverlight application), enabling ".NET RIA services". Add new item to web project - Linq2SQL dbml file (from SQL 2005 DB prepared earlier) and compile. I add a new item to the web project - domain service (link the tables I need) and compiled. Using the domain context I "Load" data with a standard RIA get query in the MainPage and add a TextBlock to display returned data. Build & run (cassini) - success. Using VS to publish to IIS on local PC - success. Using VS to publish to test server (IIS6) - browse to location and the Silverlight app loads but Fiddler tells me I've got a 404 on all the the WCF .svc requests. Use Fiddler to "launch IE" on the service request and it's true - 404. I have already run aspnet_regiis, ServiceModelReg and added mime types for .xap, .xaml, .xbap and .svc. I have included the System.Web.Ria and System.Web.DomainServices DLL with copy local true. I need help with either a) a solution b) an approach to find a solution

• Best cubicle toys for programming

  - by dlamblin

  I need some employee/co-worker Christmas gift ideas. Do you have any good cubicle toys that help you to do any of: think about programming problems solve programming problems by representing common abstractions can be directly programmed can interface with a PC based IDE to be programmed. it may present problems that can be solved, to kick start problem solving. Disallowed items are: reference material in book, pamphlet, poster or cheat-sheet form, even if it has kick ass pop-cultural references. edibles. [discuss separately] things that need their own lab-space and/or extensive tools to be worked with. So yes, Lego Mindstorms come to mind, but they aren't cubicle toys because they cost more than cubicle toys would, and they have too many losable parts. comments on the answers so far: The 20 Questions game sounds quite neat as it could get you thinking; The bean balls could be used as tokens in a problem, so I can see that working. The magnetic toys like ball of whacks or the ball-and-stick ones present hands on fun of a structural nature... now can there be a similar hands on fun toy that aids in representing a solution to a problem? The Gui Mags clearly could, but they're quite utility oriented. The AVR Butterfly is less of a toy but definitely priced attractively, cheaper and more responsive than a basic stamp. I'm not going to pick an answer; there's several great suggestions here. Thank you.

• branch prediction

  - by Alexander

  Consider the following sequence of actual outcomes for a single static branch. T means the branch is taken. N means the branch is not taken. For this question, assume that this is the only branch in the program. T T T N T N T T T N T N T T T N T N Assume a two-level branch predictor that uses one bit of branch history—i.e., a one-bit BHR. Since there is only one branch in the program, it does not matter how the BHR is concatenated with the branch PC to index the BHT. Assume that the BHT uses one-bit counters and that, again, all entries are initialized to N. Which of the branches in this sequence would be mis-predicted? Use the table below. Now I am not asking answers to this question, rather than guides and pointers on this. What does a two level branch predictor means and how does it works? What does the BHR and BHT stands for?

• How would the conversion of a custom CMS using a text-file-based database to Drupal be tackled?

  - by James Morris

  Just today I've started using Drupal for a site I'm designing/developing. For my own site http://jwm-art.net I wrote a user-unfriendly CMS in PHP. My brief experience with Drupal is making me want to convert from the CMS I wrote. A CMS whose sole method (other than comments) of automatically publishing content is by logging in via SSH and using NANO to create a plain text file in a format like so*: head<<END_HEAD title = Audio keywords= open,source,audio,sequencing,sampling,synthesis descr = Music, noise, and audio, created by James W. Morris. parent = home END_HEAD main<<END_MAIN text<<END_TEXT Digital music, noise, and audio made exclusively with @=xlink=http://www.linux-sound.org@:Linux Audio Software@_=@. END_TEXT image=gfb@--@;Accompanying image for penonpaper-c@right ilink=audio_2008 br= ilink=audio_2007 br= ilink=audio_2006 END_MAIN info=text<<END_TEXT I've been making PC based music since the early nineties - fortunately most of it only exists as tape recordings. END_TEXT ( http://jwm-art.net/dark.php?p=audio - There's just over 400 pages on there. ) *The jounal-entry form which takes some of the work out of it, has mysteriously broken. And it still required SSH access to copy the file to the main dat dir and to check I had actually remembered the format correctly and the code hadn't mis-formatted anything (which it always does). I don't want to drop all the old content (just some), but how much work would be involved in converting it, factoring into account I've been using Drupal for a day, have not written any PHP for a couple of years, and have zero knowledge of SQL? How might a team of developers tackle this? How do-able is it for one guy in his spare time?

• Silverlight 4, Out of browser, Printing, Automatic updates

  - by minal

  I have a very critial business application presently running using Winforms. The application is a very core UI shell. It accepts input data, calls a webservice on my server to do the computation, displays the results on the winforms app and finally send a print stream to the printer. Presently the application is deployed using Click-once. Moving forward, I am trying to contemplate wheather I should move the application into a Silverlight application. Couple of reasons I am thinking silverlight. Gives clients the feel that it is a cloud based solution. Can be accessed from any PC. While the clickonce app is able to do this as well, they have to install an app, and when updates are available they have to click "Yes" to update. The application presently has a drop down list of customers, this list has expanded to over 3000 records. Scrolling through the list is very painful. With Silverlight I am thinking of the auto complete ability. Out of the browser - this will be handy for those users who use the app daily. I haven't used Silverlight previous hence looking for some expert advice on a few things: Printing - does silverlight allow sending raw print data to the printer. The application prints to a Zebra Thermal label printer. I have to send raw bytes to the printer with the commands. Can this be done with SL, or will it always prompt the "Print" dialog? Out of browser - when SL apps are installed as out of browser, how to updates come through, does the app update automatically or is the user prompted to opt for update?

• General question about DirectShow.NET, DirectShow and Windows Media Format

  - by Paul Andrews

  I searched and googled for an answer but couldn't find one. Basically I'm developing a webcam/audio streaming application which should capture audio and video from a pc (usb webcam/microphone) and send them to a receiving server. What the server will do with that it's another story and phase two (which I'm skipping for now) I wrote some code using DirectShow and Windows Media Format and it worked great for capture audio/video and sending them to another client, but there's a major problem: latency. Everywhere in the internet everyone gave me the same answer: "sorry dude but media format isn't for video conferencing, their codecs have too high latency". I thought I could skip the .wmv problems but seems like it's not possible to do... this road ends here then. So I saw a few examples with DirectShow.NET which were faster for both audio and video.. my question is: how come that DirectShow.NET is faster and better for video/audio conferencing? Shouldn't it be just a .NET porting of C++'s DirectShow? Am I missing something? I'm a bit confused at this point

• Is there any special tool for interactive GUI development

  - by niko

  Hi, Currently I am preparing exercises about networks and mobile communications for students. I was thinking about creating an interactive user-interface which enables the user to drag&drop predefined elements and then implement a logic based upon element distances etc. An example would be to place two base stations (a predefined element with several properties), set the scale in the interface and then check the signal interferrence in the environment (user-interface). The first part might be too abstract whereas the example might be too specific, but I was wondering whether there already exists any friendly framework or language which enables developers to create interactive interfaces (for teaching/learning purpouses) in short ammount of time. Usually I write applications for PC environment in .NET but in this case it would take too much time to create a specific interface for every exercise. I would appreciate if anyone could suggest any way to create interactive user-interface in short ammount of time. Are there any special programming languages or development tools for this kind of applications or are there any useful frameworks for .NET, Java or any other language to speed up the development of user-interfaces? Thank you!
