• Design Patterns Recommendation for Filtering Option

  - by Tarik

  Hi people, I am thinking to create a filter object which filters and delete everything like html tags from a context. But I want it to be independent which means the design pattern I can apply will help me to add more filters in the future without effecting the current codes. I thought Abstract Factory but it seems it ain't gonna work out the way I want. So maybe builder but it looks same. I don't know I am kinda confused, some one please recommend me a design pattern which can solve my problem but before that let me elaborate the problem a little bit. Lets say I have a class which has Description field or property what ever. And I need filters which remove the things I want from this Description property. So whenever I apply the filter I can add more filter in underlying tier. So instead of re-touching the Description field, I can easily add more filters and all the filters will run for Description field and delete whatever they are supposed to delete from the Description context. I hope I could describe my problem. I think some of you ran into the same situation before. Thanks in advance...

• Standard Apache (not OHS) with mod_osso for Single Signon

  - by Markos Fragkakis

  The mod_osso.so (the Apache plugin for Single Signon, provided by Oracle) is distributed with the Oracle HTTP Server (OHS), which is essentially a modified Apache. I am trying to use it on the standard Apache HTTP Server, and have not managed to get it to work. Configuration: Apache 2.2.15 OHS from the Oracle Web Tier Tools 11.1.1.2.0 Red Hat Linux 64 bit I have: Included the module in the modules directory (copied from corresponding modules dir in OHS) Included the libraries libiau.so and libclutsh.so.11.1 from Oracle Home. The absence of these libraries produced an error on starting Apache. Produced a osso.conf using the ssoreg.sh tool provided with OID (the LDAP implementation of Oracle) Created the required mod_osso.conf file, which I included in httpd.conf. The error I get when starting Apache is this: # /opt/apache_sso/bin/apachectl -k start httpd: Syntax error on line 1075 of /opt/apache_sso/conf/httpd.conf: Syntax error on line 1 of /opt/apache_sso/conf/mod_osso.conf: Cannot load /opt/apache_sso/modules/mod_osso.so into server: /opt/apache_sso/modules/mod_osso.so: undefined symbol: _audit_authentication_request My mod_osso.conf: # cat /opt/apache_sso/conf/mod_osso.conf LoadModule osso_module modules/mod_osso.so <IfModule mod_osso.c> OssoIdleTimeout off OssoIpCheck on OssoConfigFile conf/osso.conf #Location is the URI you want to protect <Location /myapp> require valid-user #OHS 11g AuthType Osso #OHS 10g AuthType Basic AuthType Osso </Location> </IfModule> Has anyone made mod_osso work on standard Apache HTTP server?

• How to copy lots of files between two computers, without network?

  - by Steve Bennett

  I want to copy around 50Gb of files from my desktop to my work laptop. For some reason, the laptop won't connect to my home network. I haven't had any luck with a direct ethernet connection either, and I'm not willing to change any of the laptop's network configuration (last time I did that, I couldn't get onto the network at work, making me Not Very Popular). So...what else is there? The obvious route is copying via SD card. My largest card is 8Gb. But I can't find a good workflow. Is there a tool designed for this, where I could just repetitively move the card back and forth, without having to select files? I've tried using teracopy, but you end up missing a few files. I guess I could zip everything up into multi-volume .rars or something...but is there a more elegant way?

• How does firefox chose which plugin to use?

  - by Brian Postow

  I have written a plugin which allows the user to view multi-page TIFF images within firefox. The problem is that Quicktime also thinks it can view TIFF images. How does Firefox chose which one gets used? through trial and error I've determined that: Sometimes, my plugin (Accel VIewTIFF) just runs, and everyone is happy. Sometimes I need to disable Quicktime in the Add-ons window. Sometimes I need to remove the QuickTime plugin files from the / Library/Internet Plug-ins folder (I'm on a mac) Sometimes I can put QuickTime BACK after having successfully run Accel ViewTIFF. I've yet to figure out when (if ever) each step is necessary. Please help me escape the cargo cult! (or at least point me to the right place in a manual.) thanks.

• Suggestions for a nice&small - high battery life programmer notebook

  - by Emir

  Hi guys, I'm planning to buy a new notebook since the Toshiba I have now sucks in battery life. I'm a web designer & programmer, and the main features of the notebook should be: High battery life Small, 13.3" or 14" screen A fast processor and RAM that won't let me down while multi-tasking Anything other than these is secondary, I wouldn't like it to be very pricey though :) I'm now leaning towards Macbook Pro 13.3", 2.66 Ghz; it has 10 hours of battery life. However, I mostly develop on Windows, so I don't know how many hours of battery will I get if I run Windows 7 on Bootcamp. Your ideas and suggestions will be much appreciated.

• Windows Workflow Foundation - Application-Integrated Debugging

  - by user292103

  I've got a typical n-tier app that has a heavy workflow component to it, so I'm interested in using WWF. There's a server-side piece that runs as a Windows Service, and there's the client-side piece written in Silverlight. To have a really great, seamlessly integrated experience for my users, what I want is to incorporate both a workflow designer and a workflow debugger into the application. Not Visual Studio, but something tightly integrated right into the app itself. Using the Silverlight client, the user (probably more of a power user) can design workflows. But not only that, they can open a debugger from within the Silverlight client, set breakpoints (which are really remote breakpoints back to the Windows Service), catch in-process workflows, and step through them. Wouldn't that be great? I think I have some idea how I might go about incorporating an integrated designer (use a Silverlight diagramming component, save the diagram to .XAML, parse the .XAML to re-create the diagram, etc., etc.) but how on Earth would I do the debugger? I have no idea how I would do that part. Is there some kind of debugging support engineered into WWF?

• ECC RAM in GA-G33M-DS2R? Or any Gigabyte/G33M motherboard?

  - by Gregory Hoerner

  I'm looking to retire a server which has 12GB of ECC DDR2 RAM. I'd like to upgrade my multi-purpose machine (firewall, file server, VM host for Windows Home Server, etc.) using the RAM from the server. I was just wondering: Has anyone had experience using ECC RAM in a GA-G33M-DS2R motherboard (or any Gigabyte GA-G33M-XXXX motherboard for that matter)? Has anyone had experience using ECC RAM in a motherboard with a G33M chipset. I've searched everywhere and found the attitude positive of ECC memory working in a Non-ECC board, but I would like some specific positive feedback before proceeding tonight. I have to kick the entire house offline, which I don't like to do without good reason :)

• How do you keep your business rules DRY?

  - by Mario

  I periodically ponder how to best design an application whose every business rule exists in just a single location. (While I know there is no proverbial “best way” and that designs are situational, people must have a leaning toward one practice or another.) I work for a shop where they prefer to house as much of the business rules as possible in the database. This requires developers in many cases to perform identical front-end validations to avoid sending data to the database that will result in an exception—not very DRY. It grates me anytime I find myself duplicating any kind of logic—even lowly validation logic. I am a single-point-of-truth purist to an anal degree. On the other end of the spectrum, I know of shops that create dumb databases (the Rails community leans in this direction) and handle all of the business logic in a separate tier (in Rails the models would house “most” of this). Note the word “most” which implies that some business logic does end up spilling into other places (in Rails it might spill over into the controllers). In way, a clean separation of concerns where all business logic exists in a single core location is a Utopian fantasy that’s hard to uphold (n-tiered architecture or not). Furthermore, is see the “Database as a fortress” and would agree that it should be built on constraints that cause it to reject bad data. As such, I hold principles that cause a degree of angst as I attempt to balance them. How do you balance the database-as-a-fortress view with the desire to have a single-point-of-truth?

• ADSIEdit freezes gettings properties of a group with hundred of thousands members

  - by ixe013

  Doing performance testing on an AD-LDS (Server 2008 R2 64 bits), we created a milion user in a single OU. We also created a single group object and made those milion users member of that group. When we try to list the milion of users ADSIEdit times out with an error message saying it cannot display that many users. Fine. But if we open the properties for the group, ADSIEdit freezes, eating up all available memory and CPU trashing (nearly 60M page faults in under an hour). AD-LDS (running on another computer) is barely hitting the 1% CPU mark, servicing other ldap requests as if nothing were. We can throw more memory at the problem, but more users will have to be managed one day and we will be back at square one. Is there a way to set a limit in ADSIEdit so that it will not hang the computer when retreving a very large multi-value object ?

• While porting a windows application to web, is it better to stick to conventional web technologies o

  - by Kabeer

  Hello. The web based application I am working on currently is a port from a windows application. This application is very data intensive. There are scores of modules and each of these modules have number of forms (data entry screens) and reports whereas the forms have many many fields and likewise the reports. I have been trying to identify the most suitable architecture for the presentation tier. There are many functions that are not very easily portable, for example printing (this too is very complex). For most of the others, I am planning to us "Ext JS" library which looks like capable of handling about 70% of complexity out of the box while for the remaining I would be custom coding or extending Ext JS. Having said that (sorry for being so descriptive), I wonder, if this is an Intranet application, why not port the entire application to SilverLight? While I am good at .Net, I'm somewhat alien to SilverLight. Considering I know my target audience and that the software will be used per seat license, would it be better to ride on SilverLight or is it better to stick to conventional web (XHTML, JS, CSS, etc)? Further, I have to support multiple devices in future and considering that SilverLight plug-ins for many devices are yet not out, would it be a risk?

• Why would cat6 connectors not work with cat5e patch cable?

  - by Lee Tickett

  I had a naff batch of cat5 connectors (the latching mechanism didn't work) so decided to order in some cat6 connectors in preparation for the inevitable upgrade. My existing reel of for making patch cables is cat5e utp stranded. I made up a few cables and tested them- none of them worked. I recrimped and still nothing. When i check them with a multi-meter not all pins are connected. This reel has always worked with the previous cat5 connectors so I tested the cat6 connectors on a reel of solid cat5e cable and they work fine. Any ideas what I might be doing wrong? Or what might be at fault? (cable/connectors) and how I can diagnose? Thanks Lee

• Delay between printing via lp in opensuse

  - by adamweeks

  I am experiencing a 10-15 second delay when printing multiple documents to a barcode printer in opensuse. I have had the same setup on other systems with older versions of opensuse without any issue. The setup is as follows: The print queue is setup as a "generic with driver Raw Queue". The files being sent down to the printers are simple text files with the lp command: lp -dprinter1 /path/file The printer is a JetDirect compatible device (Intermec brand) with a standard 9100 port socket setup. If I send a multi-page document to the printer, it will print nonstop the multiple pages. If I send 2 or more text files down via separate "lp" commands, the delay will be there between each printout. I've tried multiple different printers and they all experience the same issue.

• .NET WF4: Should it be in the middle of everything?

  - by stimpy77

  I am aware that WF4 (Windows Workflow 4.0, part of .NET 4.0) is a significant rework and redesign of WF3, where much of what made WF3 a poor technology choice has been cleaned up in WF4. For example, as far as I can tell, WF4 (Windows Workflow 4.0) activities are more or less testable with [TestMethod] and mocking. This among other things, like improved performance, has grabbed my attention about the technology again, whereas I had previously pooh-poohed WF3. I'm working on a new architecture for essentially an n-tier collaborative application (not enterprise-class, just a smallish project with potential to grow significantly) where I'm already trying to discipline myself to use IoC and, to some extent, TDD, and I'm wondering, in general terms, whether it is wiser to just hand-code workflow logic or if I should delve into learning and integrating WF4 so that WF becomes literally the controller of the entire application, i.e. the practical C in "MVC" (not ASP.NET MVC but rather the pattern). So should workflow activities in WF4 be the primary controller for a highly expandable/growable web-based collaborative application? Or am I asking entirely the wrong question? This is a vague question, I'm sure, so abstract answers are as welcome as specific ones.

• Keep only "lock" a single app open in iOS?

  - by CT.

  Is there anyway to "lock" open a single app in iOS? My use case for this is simple. There are many apps and games designed for children. While these applications are appropriate for children, many other applications installed on an iPad are not. But even more so than protecting them from inappropriate content, I would just like to prevent them from leaving the application. They accidentally hit the home button or multi-touch gesture out of the application. I know you can turn gestures off. Developers also have links to their website or other related applications. Kids are constantly exiting the application and then bringing the device to me asking "Can you get me back into the game?" every couple minutes. How can I hand a child an iPad with "Angry Birds" running and make sure only "Angry Birds" runs? Cydia or jailbreak tweaks welcome. Thanks.

The item I am looking for is a multi word string. How do I provide a search criteria as a cell reference (E3) in to LOOKUP(E3, B1:B20, C1:C20) and have it match the value in B1:B20 EXACTLY? Right now it is matching partial strings rather than matching the cell values exactly.

• How much processor speed and cores do I need for these tasks?

  - by ajay

  I am planning to buy a new laptop as I find my current one very slow. My question here is specifically related to RAM size and CPU power. I will mostly be doing development (not much games). I would be dabbling in distributed computing, multithreaded and data intensive parallelizable tasks on multi-cores. For e.g. I would want to be able to Concurrent programming in Scala/Java/Clojure etc. and be able to see parallelization. Furthermore, I would want the RAM to be enough. But from a developer machine standpoint, do you think 4GB RAM and 2.53GHz Dual Core processor would be enough. I'm basically looking at this model: http://store.apple.com/us/configure/MC118LL/A?mco=MTM3NDcyODk (link dead)

• Online OCR website for processing an entire pdf file at one time?

  - by Tim

  I am looking for an online OCR website for processing a multi-page pdf file at one time. Free preferably. I know http://www.newocr.com/. If I am correct, it can only OCR one page at a time, by manually clicking "Preview" and then clicking "OCR" for each page. After each page is OCRed, I have to copy out the text result manually too. If my pdf file has 30~ pages, it will be tedious to repeat the above process for each page. I wonder if there is some other online websites that OCR a whole pdf file, without asking me for manual operation? Thanks!

• best ftp program (paid - not free)

  - by Victor Kimura

  Just would like some feedback on the best ftp program (not free). The requirements I'm looking for is: - secure ftp - for use on mac, linux, windows - backup utility with scheduler - for use on more than one computer (multi-license) I'm using wsftp from 2007 right now but it's only good for windows. It's license is only good for one computer. And after some vista updates it's making some strange noises. I tried to turn off the noise (via control panel) and it's still making that noise and I turned off the sound within wsftp too. I like the program but I think it's time to look for a new one. Thank you, Victor

• Green System Administrator looking for helpful tips

  - by Joshua Anderson

  I have just been promoted to Systems Administrator for our product. We are designing a application that communicates with the cloud(Amazon EC2). I will be in charge of maintaining all Instances and their underlying components. So far this involves a set of load balanced services instances that connect to a central DB in a multi-tennant DB design. Im interested in what other Sys. Admins have discovered as invaluable tools or practices. Any resources provided will be greatly appreciated.

• MODI leaking memory

  - by Khragg

  I have an app where I'm using MODI 2007 to OCR several multi-page tiff files. I have found that when I kick it off on a directory that contains several good tiffs but also some tiffs that cannot be opened in Windows Picture and Fax Viewer, then MODI also fails to OCR those "bad" tiffs. When this happens, the app is unable to reclaim any of the memory that was used by MODI to OCR those tiffs. After the tool tries to OCR too many of these "bad" tiffs, the machine runs out of memory and the app crashes. I have tried several code fixes from the web that supposedly fix any MODI memory leaks, but so far none have worked for me. I am pasting in the part of the code below that does the OCRing: StringBuilder strRecText = new StringBuilder(10000); MODI.Document doc1 = new MODI.Document(); doc1.Create(name); try { doc1.OCR(MODI.MiLANGUAGES.miLANG_ENGLISH, true, true); // this will ocr all pages of a multi-page tiff file } catch (Exception e) { doc1.Close(false); // clean up if (doc1 != null) { GC.Collect(); GC.WaitForPendingFinalizers(); GC.Collect(); GC.WaitForPendingFinalizers(); System.Runtime.InteropServices.Marshal.FinalReleaseComObject(doc1); doc1 = null; } } MODI.Images images = doc1.Images; for (int imageCounter = 0; imageCounter < images.Count; imageCounter++) { if (imageCounter > 0) { if (!noPageBreakFlag) { strRecText.Append((char)pageBreakChar); } } MODI.Image image = (MODI.Image)images[imageCounter]; MODI.Layout layout = image.Layout; strRecText.Append(layout.Text); GC.Collect(); GC.WaitForPendingFinalizers(); GC.Collect(); GC.WaitForPendingFinalizers(); if (layout != null) { System.Runtime.InteropServices.Marshal.FinalReleaseComObject(layout); layout = null; } if (image != null) { System.Runtime.InteropServices.Marshal.FinalReleaseComObject(image); image = null; } } File.AppendAllText(ocrFile, strRecText.ToString()); // write the OCR file out to disk GC.Collect(); GC.WaitForPendingFinalizers(); GC.Collect(); GC.WaitForPendingFinalizers(); if (images != null) { System.Runtime.InteropServices.Marshal.FinalReleaseComObject(images); images = null; } GC.Collect(); GC.WaitForPendingFinalizers(); GC.Collect(); GC.WaitForPendingFinalizers(); doc1.Close(false); // clean up if (doc1 != null) { System.Runtime.InteropServices.Marshal.FinalReleaseComObject(doc1); doc1 = null; } GC.Collect(); GC.WaitForPendingFinalizers(); GC.Collect(); GC.WaitForPendingFinalizers();

• How to edit multilevel list in Word 2011 Mac

  - by Tim Kemp

  I use the multilevel list feature in Word as described here to set up proper nested numbering linked to styles. I did this on Windows, and it worked well. Now I am editing the documents on my Mac using Word 2011. I need to modify the list style; I can create a new multi-level list style from the toolbar dropdown, but I can't right-click to edit an existing one. How can I edit my existing list style on Word for Mac? Thanks
