• THE FASTEST Smarty Cache Handler

  - by rob.effect

  Does anyone know if there is an overview of the performance of different cache handlers for smarty? I compared smarty file cache with a memcache handler, but it seemed memcache has a negative impact on performance. I figured there would be a faster way to cache than through the filesystem... am I wrong?

• Machine learning - training step

  - by palau1

  When you're using Haar-like features for your training data for an Adaboost algorithm, how do you build your data sets? Do you literally have to find thousands of positive and negative samples? There must be a more efficient way of doing this... I'm trying to analyze images in matlab (not faces) and am relatively new to image processing.

  I'm displaying a list of events. I wanted displayed the page with the events for today by default. That was easy accomplished by: page = number_of_records_before_RECORD / number_of_pages + 1 Now I want to display the first item of today's events as the first item in that page. Maybe there is a way to generate page numbers around a record with negative values to get back.

• Programmer tendency to preach [closed]

  - by Daniel

  I've run across several SO posts that come across as preachy or condescending. Do pedagogical programmers feel plagued by thoughtless questions? Or, do programmers count self-sufficiency such a virtue that any perceived lack of ambition merits scolding? These are some theories, admittedly negative ones. Can anyone offer some insight?

• crows foot notation in Visio 2007

  - by user10487

  I'm using the standard Database Model Diagram template in Visio 2007. When I try to connect two entities, the line is a "one and only one" type. I need a "zero or more" type, but no amount of line editing will change the line. Is this a bug? The Visio help does not describe how to do this and the MS website turns up no results for 2007 (plenty for 2003, but the menu options it refers to are not in 2007).

• I want to execute the commands in a loop at the same time, not one after another

  - by Felipe Alvarez

  I'd like to write a loop ('for') that will do some action 'X' number of times.

Script or a one liner are fine. example ONLY: for i in 1 2 3 4 5; do dd if=/dev/zero of=/tmp/disk$i bs=10M count=10; done

  As all mail things change I wanted to get some thought if checking PTR DNS records these days is advisable? 1) I do want to use it if it will actually bring benefit and 2) I do need to keep false positives as close to zero as possible.

• RFC2616 : Do I really need to set WWW_Authenticate when returning 401?

  - by Chris McCauley

  According to RFC2616 if I return 401 in response to a request to my (Ruby) server, I "MUST include a WWW-Authenticate header field." Is this really true? Not setting the header seems to have no negative impact. I'm using Merb as a web framework and it doesn't force me to set the header. Am I missing something or is this a rule more honoured in the breach?
