  • Understanding exceptional cases

    - by Justin
    I've been studying the use of exceptions in various php projects (such as Doctrine and Zend Framework). Exceptions seem to be thrown when unordinary input/state occurs. A perfect example is Doctrine throwing an exception when you try to use a invalid query string. I think the creators of the doctrine api understood that first, you can't query data by using an invalid DQL statement, and a developer should immediately be warned that an error has occurred, rather then letting execution continue with the possibility of an error code going un-checked. I also bet that this simplifies reading the code. I can't think of a situation where you would want to use an invalid DQL statement, except unit testing. Since this is true, it's better to avoid plaguing a bunch of code with null/error checks and use exceptions. I've read in books that exceptions shouldn't be thrown when validating dating user input. I've seen examples where of where the guideline is broken. One example is the Zend framework. If supplying an invalid controller or action name, an exception is thrown. Unlike doctrine, the user has more direct control over this sort of input. I know you can configure an error controller and set up a 404 message or what have you, but I'm curious why they have used an exception in this scenario? I guess you can argue the Zend Framework does not know how to continue processing the quest. One last example Is I wrote a function to return some html based on a given resource type. This resource type is hard-coded and sent when a user interacts with a web site (such as clicking a button to display the form to input data). I don't expect users to be mucking around with the request type. Under normal operating conditions, the resource type should be valid. To clean up some logic, I was going to throw an exception if a particular form wasn't found. This is mainly to find the correct form associated with a resource type so proper validation can occur. Does this sound like a valid use case for an exception? Right now it's pretty trivial, but I do plan to implement a restful consumer and re-using a function to map resources to their validation services would be very useful. I can then catch the exception and based on the consumer, return an error message suitable for the request type...

  • samsung printer SCX 5737FW on Ubuntu 11.10

    - by Pepe
    can anyone please help? I am trying to install samsung printer SCX 5737FW on Ubuntu 11.10, but when I plug in the usb cable it tries to look for the driver, but can't find it. Indeed the webpage http://www.samsung.com/uk/consumer/print-solutions/print-solutions/mono-multi-function-products/SCX-5737FW/SEE-spec tells me that the printer is supported up to Ubuntu 10. This true because it installs perfectly on my other machine with ubuntu 9. Can anyone help please? Thanks

  • windows azure thoughts.

    - by foxjazz
    Well I had a relatively unpleasant exprience with Microsoft's new offerings when it comes to azure.And of course they deleted the forum trail.They don't want the consumer as a customer, expect to pay $200 - $250 or more a year for azure and that doesn't include a good email solution. This is for the smallest slice offering.If you want a simple website solution 1and1.com isn't a bad choice and it's less than $50 a year.

  • If you are in Brussels next week... come join a policy dialog on the European Accessibility Act

    - by Peter Korn
    Next week I will be in Brussels attending a policy dialog held at the European Policy Centre on Thursday October 11th. It is titled "The Accessibility Act – ensuring access to goods and services across the EU", and I will be part of a distinguished panel exploring some of the issues the upcoming European Accessibility Act may address - with a particular emphasis in my case on the role of ICT accessibility. This morning policy dialog will be followed by a more focused workshop in the afternoon looking at specific challenges and potential solutions to those challenges. Oracle is sponsoring this policy dialog and workshop, alongside the European Disability Forum. If you are in Brussels, you are invited to attend. Registration by e-mail is now open.

  • Is it possible to pay customers with PayPal?

    - by CJxD
    Usually with PayPal we buy goods and services by sending money from customer to business. Now, I want my business to pay my customers; I want to allow them to withdraw money from a virtual wallet on my website. I did notice there is an 'Adaptive Payments API' which mentioned something vaguely similar to this, but I haven't been able to search up enough information to come to any conclusion. So is it possible to send money from business to customer (autonomously) with PayPal? If not, are there any alternatives?

  • Would opencv be a good choice for image colour summarization?

    - by codecowboy
    I would like to analyse a set of hundreds of thousands of product images (clothing, electronic goods etc) and retrieve the dominant colours in each. I'm only interested in the top 3 or 4 colours. The aim is to achieve a degree of certainty that x image is mostly red or image y is mostly orange and blue. The images are likely to be colour jpegs of reasonable quality and approximately 100kb in size. I would like to use C# and the solution should run on a Linux server, preferably using open source libraries. Would opencv be a good choice for this? What other libraries or specific algorithms might be helpful?

    In a world where people continents apart work together for that same cause, and may not even know it, it can be confusing to hire someone when you cannot be familiar with them.
