php - Facebook's HipHop - What's it for? -


Today's PHP is the news in the world, which:

Hip hop is for PHP Technically, a compiler is itself a source code transformer, HipHop programmatically changes your PHP source code to highly optimized C ++ and then uses G ++ to compile it. Hip hop performs the source code in a manner consistently and uses some of the less-used features - such as eval () - in exchange for better performance.

My question is, what types of web applications are, code transformers in Hiphop, a revision of PHP runtime system, and rewriting of many common PHP extensions. Is it really useful for?

It seems that the typical database-bound web application can not be done much by this, but there will be rare CPU-bound apps.

Web applications that use lots of processing and / or memory, apparently this hip hop CPU Reduce usage by about 50% and reduce memory usage (I did not know how much memory usage would be mentioned). This means that you should be able to request the same number with fewer servers.

An additional advantage may be that there should be some basic type of inquiry to ensure that the code is compatible before compiling it. This should help in the generation of bugs as a result of a weak type of system.

The downside appears to be that it has some of PHP's more dynamic features like eval (though arguably it's also a positive one).

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
