  • PostGreSQL load increasing over time, why?

    - by TravisO
    It's a CentOS server (I don't know the specs) and just before anybody states the obvious, keep in mind these mitigating factors: the server does a nightly VACUUM job all the tables are indexed it's pretty much read only (meaning the DBs are not increasing in size) the number of queries being ran has been the same every month Here's a graph of the server load:

  • How does PHP work - literature

    - by Ondrej Slinták
    I'm interested in literature (articles on internet, in magazines, books, podcasts - I don't really mind anything) that describes how PHP works internally, about its gotchas and perhaps some advanced functions. Is there anything like this out there? I tried to search on Google, but majority of articles were about starting with PHP and its basic functions. Any input is really welcome as I'm trying to understand the language internally - I'm tired of my mindless typing of code without understanding its essence.

  • Other HTML serialisations?

    - by Delan Azabani
    After keeping in mind that HTML has both an SGML and XML serialisations, which are just encodings for a parser to "explode" into a DOM, I'm wondering whether there are other serialisations for HTML. A JSON serialisation? If so, are there any parsers for these alternative serialisations?

  • Scrapy - Follow RSS links

    - by Tupak Goliam
    Hello, I was wondering if anyone ever tried to extract/follow RSS links using SgmlLinkExtractor/CrawlSpider. I can't get it to work... I am using the following rule: rules = ( Rule(SgmlLinkExtractor(tags=('link',), attrs=False), follow=True, callback='parse_article'), ) (having in mind that rss links are located in the link tag). I am not sure how to tell SgmlLinkExtractor to extract the text() of the link and not to search the attributes ... Any help is welcome, Thanks in advance

  • Testing a db structure before beginnning to code the app

    - by driverate
    I'm in the beginning stages of writing (and learning as I go) a Python database app using SQLite. I have the db structure planned on paper, and I have the queries I'll need in mind, but before I start coding I want to fully test the db design so I know it's right and ready. What's the best free software to use to test the db structure quickest?

Now, I want to remove the transperant background too and just keep the faces. Don't know if this is possible and mind you, this isn't a programming question.

  • Business Logics on the client side

    - by Ivo Rossi
    Why do people say that business logics should be implemented on the server side code (e.g. EJB) and not on the client application code? The example that I have in mind is a business object validation on a EJB based architecture. Does it really have to be delegated to the EJB or is it ok to run it on the client before the object is sent to be server to be saved?

  • Commercial Java LIB / API to read and write Word 2007 docs

    - by AlfaTeK
    I need a simple to use / good docs / good support java lib to read and write word documents, namely word 2007 support (and word 2010 support planned). As the project I'm in has budget and time-constraints I don't mind buying a commercial lib :) I know they are XML files in a somewhat open format but I really don't want to waste time understanding the XML specification. Any good recommendations from happy customers? (Right now my choice is going to Aspose.Words for Java)

  • Form Builder GUI for PHP

    - by Alan Storm
    I'm looking around for an open source form building package for PHP, and figured the hive-mob-mind of StackOverflow might be able to tilt me in the right direction. Specifically, I'm looking for a form/survey builder application. I want something that lets an end user use a web based GUI to create and configure/surveys and web-based forms. What are the de-facto standard tools/packages that people use for this kind of thing these days. I'm interested in software packages, not in hosted services.

  • What's the best way to reference a .DLL - as a normal reference or as a web service?

    - by dotnetdev
    Hi, What is the best way to reference an existing .NET dll (Class library)? Is there any benefit to expose web services from the class library and reference these as opposed to referencing the actual .dll (Although one benefit of the web service approach is the granularity and thus surface area exposed is up to you at coding time)? I am thinking with loose coupling in mind, as a criteria. Thanks

  • Using JavaScript's split to chop up a string and put it in two arrays

    - by Pieter
    I can use JavaScript's split to put a comma-separated list of items in an array: var mystring = "a,b,c,d,e"; var myarray = mystring.split(","); What I have in mind is a little more complicated. I have this dictionary-esque string: myvalue=0;othervalue=1;anothervalue=0; How do I split this so that the keys end up in one array and the values end up in another array?

  • How is Java Process.getOutputStream() Implemented?

    - by Amit Kumar
    I know the answer depends on the particular JVM, but I would like to understand how it is usually implemented? Is it in terms of popen (posix)? In terms of efficiency do I need to keep something in mind (other than using a Buffered stream as suggested by the javadoc). I would be interested to know if there is a general reference about implementations of JVMs which answers such questions.
