• dao as a member of a servlet - normal?

  - by EugeneP

  I guess, DAO is thread safe, does not use any class members. So can it be used without any problem as a private field of a Servlet ? We need only one copy, and multiple threads can access it simultaneously, so why bother creating a local variable, right?

• Monotouch Augmented Reality

  - by cvista

  Hi I'm trying to use the code posted here: http://seanho.posterous.com/monotouch-first-attempt-arkit-c-version however - when i try to overlay it on a camera - it seems to behave really strangely. I'm guess that it's because the camera view only does portrait? Has anyone succesfully used this? Or maybe know's how to get this working? Cheers w://

• login restriction with ldap, but where to store the functional rights/access control list?

  - by jrEwing

  Question is: Best practices when using LDAP authentication like MS ActiveDirectory but having complex access control rights inside each application. Did you put it all in the LDAP or did you link it with information in the application? Looking to build this in asp.net mvc 2 and using membership features, so best practice here i guess is that we roll our own custom provider to acomplish this...

• Idiomatic scheme and generic programming, why only on numbers ?

  - by Skeptic

  Hi, In Scheme, procedures like +, -, *, / works on different types of numbers, but we don't much see any other generic procedures. For example, length works only on list so that vector-length and string-length are needed. I guess it comes from the fact that the language doesn't really offer any mechanism for defining generic procedure (except cond of course) like "type classes" in Haskell or a standardized object system. Is there an idiomatic scheme way to handle generic procedures that I'm not aware of ?

• What is the most painful development related mistake you have done and what you have learned?

  - by burak ozdogan

  What is the most painful programming mistake you have done and what lesson you have learn after? I guess mine was making a release to production on the development code which was not tested yet. The lesson-learned: Delete any projects that can trigger a release on the live application from CCTray. I only add them when a release to production is necessary since then. And once I am done, I delete them from my project lists.

• Can regex match be based on two lines of text?

  - by Matt

  Let's say I have def abc xyz abc And I want to match xyz abc as a whole Is this possible using the most generic RegEx possible? That is not the perl RegEx or .Net Regex which have multi line flags. I guess it would be BNF to match this.

• echo "-e" doesn't print anything

  - by wheleph

  I'm using GNU bash, version 3.00.15(1)-release (x86_64-redhat-linux-gnu). And this command: echo "-e" doesn't print anything. I guess this is because "-e" is one of a valid options of echo command because echo "-n" and echo "-E" (the other two options) also produce empty strings. The question is how to escape the sequence "-e" for echo to get the natural output ("-e").

• How computer multiplies 2 numbers?

  - by ckv

  How does a computer perform a multiplication on 2 numbers say 100 * 55. My guess was that the computer did repeated addition to achieve multiplication. Of course this could be the case for integer numbers. However for floating point numbers there must be some other logic. Note: This was asked in an interview.

• javascript getElementByName doesn't work

  - by phil

  This simple js script can't set the value of "para". I guess getElementByName doesn't work. But why? <script function fn() { document.getElementById("para").setAttribute("name","hi"); document.getElementByName("hi").setAttribute("value","my value is high"); } </script <html <input type="button" onClick="fn()" value="click me" <input id="para" type="text" / </html

• Outputcache - how to determine optimal value for duration?

  - by Steve

  I read somewhere that for a high traffic site (I guess that is a murky term as well), 30 - 60 seconds is a good value. Obviously I could do a load test and vary the values, but I couldn't find any kind of documentation on this. Most samples have a minute, a couple of minutes. There's no recommended range. Is there something on msdn or anywhere that talks about this?

• is it possible to continue a file upload after a browser has been quit?

  - by sprugman

  If a user starts uploading a file (in a web app), and they close their browser before the upload completes, what happens? My guess would be that the upload gets abandoned, and the server has some garbage cleaning mechanism that kicks in eventually, but I'm not sure. Any difference between servers or server languages? Any difference between quitting the browser and just closing a window?

• What time/date do you stamp your deployed data/exe files when they appear on the target system?

  - by Brian Frost

  It seems a good and clean thing to ensure that your deployed files appear on the target system with a consistent time/date. Many Applications seem to do this but other than for care of overwriting Users' existing data I guess it has no real significance. I'm having a purge on my installer packaging and I'd like to know if there any good reasons for specific date/time handling.

• Twisted + SQLAlchemy and the best way to do it.

  - by Khorkrak

  So I'm writing yet another Twisted based daemon. It'll have an xmlrpc interface as usual so I can easily communicate with it and have other processes interchange data with it as needed. This daemon needs to access a database. We've been using SQL Alchemy in place of hard coding SQL strings for our latest projects - those mostly done for web apps in Pylons. We'd like to do the same for this app and re-use library code that makes use of SQL Alchemy. So what to do? Well of course since that library was written for use in a Pylons app it's all the straight-forward blocking style code that everyone is accustomed to and all of the non-blocking is magically handled by Pylons via threading, thread locals, scoped sessions and so on. So now for Twisted I guess I'm a bit stuck. I could: Just write the sql I need directly if it's minimal and use the dbapi pool in twisted to do runInteractions etc when I need to hit the db. Use the objects and inherently blocking methods in our library and block now and then in my Twisted daemon. Bah. Use sAsync which was last updated in 2008 and kind of reuse the models we have defined already but not really and it does address code that needs to work in Pylons either. Does that even work with the latest version SQL Alchemy? Who knows. That project looked great though - why was it apparently abandoned? Spawn a separate subprocess and have it deal with the library code and all it's blocking, the results being returned back to my daemon when ready as objects marshalled via YAML over xmlrpc. Use deferToThread and then expunge the objects returned having made sure to do eager loads so that I have all my stuff that I might need. Seems kind of ugha to me. I'm also stuck using Python 2.5.4 atm so no 2.6 yet and I don't think I can just do an import from future to get access to the cool new multiprocessing module stuff in there. That's OK though I guess as we've got dealing with interprocess communication down pretty well. So I'm leaning towards option 4 mostly as that would avoid the mortal sin of logic duplication with option 1 while also staying the heck away from threads. Any better ideas?

• How to delete Tomcat Access Log after n days?

  - by Andreas

  I only would like to keep the Access Logs of the last n days created by Tomcat Access Log Valve. http://tomcat.apache.org/tomcat-6.0-doc/config/valve.html#Access%20Log%20Valve But there seems to be no configuration-Attribute to define how long to keep the log-files? I guess this is because "Access Log Valve" only creates log files and doesn't delete them, is that correct?
