• How do I serve a large file using Pylons?

  - by Chris R

  I am writing a Pylons-based download gateway. The gateway's client will address files by ID: /file_gw/download/1 Internally, the file itself is accessed via HTTP from an internal file server: http://internal-srv/path/to/file_1.content The files may be quite large, so I want to stream the content. I store metadata about the file in a StoredFile model object: class StoredFile(Base): id = Column(Integer, primary_key=True) name = Column(String) size = Column(Integer) content_type = Column(String) url = Column(String) Given this, what's the best (ie: most architecturally-sound, performant, et al) way to write my file_gw controller?

• Regex: Match any character (including whitespace) except a comma

  - by selecsosi

  I would like to match any character and any whitespace except comma with regex. Only matching any character except comma gives me: [^,]* but I also want to match any whitespace characters, tabs, space, newline, etc. anywhere in the string. For example, I would like to be able to match all of this up until the comma: "bla bla bla" "asdfasdfasdfasdfasdfasdf" "asdfasdfasdf", Is there a simple way to do this without knowing where the whitespace may be?

Can I be sure that this works always or do have have to use nested if statements?

• Open SSL without SHA1

  - by Hellnar

  Is there any way to use Open SSL without any SHA1 hash functions and using one of SHA2 functions instead of it? I think firstly, I should find all the functions that call SHA1 algorithm, and I should understand why SHA1 is still used. While changing the hash function, the bits are different in SHA1 and SHA2 so it may cause some problems. It confuses me...

• Floating point arithmetics restricted to integers

  - by user396672

  I use doubles for a uniform implementation of some arithmetic calculations. These calculations may be actually applied to integers too, but there are no C++-like templates in Java and I don't want to duplicate the implementation code, so I simply use "double" version for ints. Does JVM spec guarantees the correctness of integer operations such a <=,=, +, -, *, and / (in case of remainder==0) when the operations are emulated as corresponding floating point ops? (Any integer, of course, has reasonable size to be represented in double's mantissa)

• Where to define exception classes, inside classes or on a higher level?

  - by rve

  Should exception classes be part of the class which may throw them or should they exist on a higher level? For example : class Test { public: class FooException: public ExceptionBase { }; void functionThrowingFooException(); }; or class FooException: public ExceptionBase { }; class Test { public: void functionThrowingFooException(); }; (functionThrowingFooException() is the only function to ever throw a FooException)

• MySQL: LOAD DATA reclaim disk space after delete

  - by Michael

  I have a DB schema composed of MYISAM tables, i am interested to delete old records from time to time from some of the tables. I know that delete does not reclaim the memory space, but as i found in a description of DELETE command, inserts may reuse the space deleted In MyISAM tables, deleted rows are maintained in a linked list and subsequent INSERT operations reuse old row positions. I am interested if LOAD DATA command also reuses the deleted space? UPDATE I am also interested how the index space reclaimed?

• How to instantiate a particular view controller with storyboard in iOS at early stage of loading?

  - by dmirkitanov

  When using tabs with storyboard in iOS 5, some of them may take quite a long time to initialize when switching to it (for example, a tab containing GLKViewController). This happens because an amount of work in viewDidLoad method in this controller could be very big. Is there a way to initialize particular view controller (and call it's viewDidLoad method) defined in the storyboard at early stage - when an application starts? Having done this, the delay should be eliminated.

• form validation without reset

  - by Paulo Bueno

  Hi guys Is there a way to check the data sent by a form to a PHP page return to the form page WITHOUT resetting the data sent and show a error? The form has 20 fields and I need to check one of them on a bd. If it fails the user may be redirected to the form page with the form populated and displaying a error message on the field which is 'wrong'. I would like any advice of a technique instead of populating each field using PHP.

• Implementation of interface when using child class of a parent class in method of interface

  - by dotnetdev

  I don't have access to my dev environment, but when I write the below: interface IExample void Test (HtmlControl ctrl); class Example : IExample { public void Test (HtmlTextArea area) { } I get an error stating the methods in the class implementation don't match the interface - so this is not possible. HtmlTextArea is a child class of HtmlControl, is there no way this is possible? I tried with .NET 3.5, but .NET 4.0 may be different (I am interested in any solution with either framework). Thanks

• What is the preferred syntax for initializing a dict?

  - by daotoad

  I'm putting in some effort to learn Python, and I am paying close attention to common coding standards. This may seem like a pointlessly nit-picky question, but I am trying to focus on best-practices as I learn, so I don't have to unlearn any 'bad' habits. I see two common methods for initializing a dict: a = { 'a': 'value', 'another': 'value', } b = dict( a='value', another='value', ) Which is considered to be "more pythonic"? Which do you use? Why?
