  • PHP Sessions data lost when changing directory?

    - by Ineffable
    I've got a simple login system using PHP sessions, but just recently it seems that if you visit pages not in a certain directory (/login/) you will always be flagged as not logged in, even when you are. It seems that my session data is being lost when I change directories (say, to /login/user/). I don't think I've touched the code myself since the problem appeared, is there something my web host could have done to my PHP installation that would delete the session data, and is there a workaround?

  • What is the most robust way of determining the current codepage from a shell script?

    - by rewbs
    Hi all, I'd like to determine the environment's current codepage at runtime from a Unix shell script. What's the most reliable way of doing this? I'm looking into parsing environment variable $LC_ALL, but it isn't always set to a useful value, and its format seems to vary (can be <locale, or <locale.<code page, or <locale.<code page@<modifier etc...). Is there a better way? I'm essentially after a shell equivalent of what I'd get if I called nl_langinfo(CODESET) from C.

  • Is the W3 standard a major factor when google decides SERP position?

    - by Camran
    I have a dynamic php website which index only has around 800 errors according to the w3 validator online. I have tried checking major websites like ebay, stackoverflow and others also, all with around 400 errors. So my first thought is, what good is that validator when it always displays errors? Secondly, will the errors affect my SERP ranking? ie, will me fixing these errors as good as I can increase my Google search position? Thanks

  • InternetCheckConnection in VB6 returning false

    - by user191582
    Hi all, Not a VB6 expert... Trying to come up with a VB6 test app that calls InternetCheckConnection. In my test app, InternetCheckConnection always returns false regardless of the URL I use. I copied and pasted this code from a larger spaghetti-code app, but in the spaghetti-code, InternetCheckConnection seems to work fine, returns true. Is there some other function I have to call first in order for InternetCheckConnection to work?

  • About the armlink behavior when the linked object is not explicitly used by the main executable

    - by thincal
    I want to link the example with liba.so, and also the example is NOT using anything inside the liba.so ... armlink --userlibpath /mylib/lib liba.so --fpic --shared -o example main.o demo.o So finally I got nothing from: readelf -d example | grep NEEDED, it seems that armlink do some optimization to remove the linked library which is not really used by the "example" ? If I want to let the liba.so be always linked into example, what need I do with armlink options ? Any information is very appreciated ;)

  • persistant message queues

    - by Will
    I have several services on different machines and a message-passing system suits my problem. Reliability - sent messages always delivered, even if one end goes down - is the key concern, although it should also be fast and reasonably bandwidth-efficient. So which message queue should I use?

    - by markus

  • MySQL: how to index an "OR" clause

    - by JoséMi
    I'm executing the following query SELECT COUNT(*) FROM table WHERE field1='value' AND (field2 = 1000 OR field3 = 2000) There is one index over field1 and another composited over field2&field3. I see MySQL always selects the field1 index and then makes a join using the other two fields which is quite bad because it needs to join 146.000 rows. Suggestions on how to improve this? Thanks

  • Neural Network: Handling unavailable inputs

    - by Mike
    Hopefully the last NN question you'll get from me this weekend, but here goes :) Is there a way to handle an input that you "don't always know"... so it doesn't affect the weightings somehow? Soo... if I ask someone if they are male or female and they would not like to answer, is there a way to disregard this input? Perhaps by placing it squarely in the centre? (assuming 1,0 inputs at 0.5?) Thanks

  • quoting HTML attribute values

    - by Flavius
    Hi I know the spec allows both ' and " as delimiters for attribute values, and I also know it's a good practice to always quote. However I consider " being the cleaner way, maybe it's just me having grown up with C and C++' syntax. What is the cleanest way of quoting attribute values and why? Please no subjective answers.

  • Performance impact using culture invariant resources

    - by Praveen S
    I would like to know the performance impact of using the culture invariant resources instead of culture specific ones. For example, we plan to deploy a website and not have any en-US resources. This is because our culture invariant resources are always identical to the en-US resources. Is this a good idea ? What are the cons?

  • Java overloading and overriding

    - by Padmanabh
    We always say that method overloading is static polymorphism and overriding is runtime polymorphism. What exactly do we mean by static here? Is the call to a method resolved on compiling the code? So whats the difference between normal method call and calling a final method? Which one is linked at compile time?
