  • How can I convert (string) timestamp to mysql datetime on Windows 32 bit PHP?

    - by user239619
    I'm attempting to call LinkedIn's API and store Network Updates. Each update has a Unix timestamp that I'm retrieving as a string variable from the REST XML response. I want to convert the string timestamp to a mysql datetime format. The date() function accepts an integer as the second argument for time to be converted. However, I'm on Windows 32 bit PHP and the integer type for this platform is limited to 2147483647. $timestamp = '1293714626675'; // sample pulled from linkedin $timestamp = (int) $timestamp; // timestamp now equals 2147483647 $mysqlDatetime = date('Y-m-d H:i:s', $timestamp); // produces incorrect time Is there a better method of creating the mysql datetime in PHP? I realize that I can convert it upon insert into MySQL however, that would require changing other dependent code.

  • Username correct, password incorrect?

    - by jonnnnnnnnnie
    In a login system, how can you tell if the user has entered the password incorrectly? Do you perform two SQL queries, one to find the username, and then one to find the username and matching (salted+hashed etc) password? I'm asking this because If the user entered the password incorrectly, I want to update the failed_login_attempts column I have. If you perform two queries wouldn't that increase overhead? If you did a query like this, how would you tell if the password entered was correct or not, or whether the username doesn't exist: SELECT * FROM author WHERE username = '$username' AND password = '$password' LIMIT 1 ( ^ NB: I'm keeping it simple, will use hash and salt, and will sanitize input in real one.) Something like this: $user = perform_Query() // get username and password? if ($user['username'] == $username && $user['password'] == $password) { return $user; } elseif($user['username'] == $username && $user['password'] !== $password) { // here the password doesn't match // update failed_login_attemps += 1 }

  • How to avoid that the robot gets trapped in local minimum?

    - by nesmoht
    Hi, I have some time occupying myself with motion planning for robots, and have for some time wanted to explore the possibility of improving the opportunities as "potential field" method offers. My challenge is to avoid that the robot gets trapped in "local minimum" when using the "potential field" method. Instead of using a "random walk" approach to avoid that the robot gets trapped I have thought about whether it is possible to implement a variation of A* which could act as a sort of guide for precisely to avoid that the robot gets trapped in "local minimum". Is there some of the experiences of this kind, or can refer to literature, which avoids local minimum in a more effective way than the one used in the "random walk" approach.

  • where id = multiple artists

    - by pixel
    Any time there is an update within my music community (song comment, artist update, new song added, yadda yadda yadda), a new row is inserted in my "updates" table. The row houses the artist id involved along with other information (what type of change, time and date, etc). My users have a "favorite artists" section where they can do just that -- mark artists as their favorites. As such, I'd like to create a new feature that shows the user the changes made to their various favorite artists. How should I be doing this efficiently? SELECT * FROM table_updates WHERE artist_id = 1 and artist_id = 500 and artist_id = 60032 Keep in mind, a user could have 43,000 of our artists marked as a favorite. Thoughts?

  • Sharing Eclipse directory on Dropbox between Windows and Mac OS X

    - by sowbug
    This question was close to mine, but not quite. I have a Windows desktop and a MacBook Pro. I'd like to be able to keep my Eclipse workspace in my Dropbox folder. The problem is that many project settings change between platforms: references to JREs, JDKs, and other libs. Every discussion I've seen of this problem seems to suggest taking advantage of the source control system's ignore functionality, so that such-and-such file remains local-only and thus able to remain platform-specific. But when you're working with a real single shared folder, that class of solution doesn't apply. Have you had luck working with a Java Eclipse project living in a single folder shared over the network, cross-platform?

  • The importance of knowing c++ for web application development

    - by neitony
    I'm a php developer and I want to broaden my knowledge base by learning a higher language (java, c#, c++). My specialty is in building web applications (ria etc). I'm trying to think of the appropriate path to take (hedging my bets so to speak) in terms of which language I should be focusing on. I love open source technology but at the same time C# seems to be getting a lot of notoriety. Despite the newer technologies available there still remains c++ which is the staple for many popular vendors including google and facebook (hip hop) in building scalable and robust cross platform apps. Can anyone offer suggestions as to how I should be looking at this. Should I go Java, C# or C++). They all take time to master and I just want to choose a specialty. Thanks

  • VSS Analyze - Access to file [filename] is denied

    - by AJ
    Our VSS database appears to be horribly out of shape. I've been trying to archive and run "analyze" and keep getting "Access to file [filename] is denied. The file may be read-only, may be in use, or you may not have permission to write to the file. Correct this problem and run analyze again." No one is logged into SourceSafe (including myself) and I'm running the analyze utility from the VS command prompt as follows: analyze -v -f -bbackuppath databasepath I get similar errors if I try and create project archives from the ssadmin tool. The database is on a network share, and we're running VSS 2005 v8.0.50727.42. I'd love to be able to do this, as it would be a first step in a move away from VSS. Thanks in advance. More Info Every time I run analyze, the file that spawns the access denied message changes. It's almost as if running analyze unlocks that file so that the next time I get through to the next one.

  • JavaScript - Is it possible to get height from div in separate page?

    - by Kenny Bones
    Hi, I'm wondering, is it possible to collect the height of a specific div container from a separate page with JavaScript? I'm using jQuery btw and I'm in need of comparing heights of div containers. Edit: To clarify a bit more, I load content from a specific div in a separate page using jQuery. This content is faded into a different container with dynamic height. But in the small fraction of time before the content arrives, it shrinks down to it's min-height. What I've done so far is collecting the height of the container before and after the load. But it only works after I've loaded content once. Because I don't have the height before it's been loaded the first time.

  • Extendable accessing of sqlite database on android platform

    - by mscriven
    Hi, I am fairly new to the android sdk and databases and have been searching for an answer to this quite some time. I am trying to build an app which has multiple tables within a database. e.g. one for weapons, armours etc. However, my DatabaseManager class which handles all of my table creating, DatabaseHelper inner class and populating of data is creating for an extremely large class requiring high maintenance. Every time I would like to add or remove a table column I need to change quite a few areas of code, - Every reference to the addition of a row in that table with data - The method that the above calls - The method returning all of the database rows - The code in the helper class creating the table - Any specific update methods My question is this: Surely there must be some better way of coding this system, maybe using a database isn't the best way to go, or am i just not used to such large classes having only learned java at university and my largest class consisting of a mere 400-600 lines of code. Thanks for any help!

  • When convert a void pointer to a specific type pointer, which casting symbol is better, static_cast or reinterpret_cast?

    - by BugCreater
    A beginner question with poor English: Here I got a void* param and want to cast(or change) it to a specific type. But I don't know which "casting symbol" to use. Either**static_cast** and reinterpret_cast works. I want to know which one is better? which one does the Standard C++ recommend? typedef struct { int a; }A, *PA; int foo(void* a) // the real type of a is A* { A* pA = static_cast<A*>(a); // or A* pA = reinterpret_cast<A*>(a);? cout<<pA->a<<endl; return 0; } Here I use A* pA = static_cast(a); or A* pA = reinterpret_cast(a); is more proper?

  • What is the advantage of creating an enumerable object using to_enum in Ruby?

    - by Jason
    Hi, Why would you create a proxy reference to an object in Ruby, by using the to_enum method rather than just using the object directly? I cannot think of any practical use for this, trying to understand this concept & where someone might use it, but all the examples I have seen seem very trivial. For example, why use: "hello".enum_for(:each_char).map {|c| c.succ } instead of "hello".each_char.map {|c| c.succ } I know this is a very simple example, does anyone have any real-world examples? Thanks!

  • How to access device settings on a S60 symbian based mobile phone?

    - by TheRHCP
    Hello everyone, I recently bought a Sony Ericsson mobile phone which embeds Symbian S60 and I would like to add a missing feature myself. In fact I cannot actually disable Internet connection in an easy way when roaming, which cost me a lot of money last time I moved away ... So I would like to develop a little application that would just replace the actual Internet configuration with a fake configuration to avoid auto-connections. So what I would like to know is how can I access programmatically to my phone settings? I believe that this is possible but I do not really have a clue where to start. I know that Sony Ericsson provides a SDK to run Java applications on its customised JVM but Symbian is also providing a SDK to develop applications for S60 devices in many languages. The real questions is which SDK will provide an API able to access phone settings. This is not well documented so I am asking this question with the hope that someone here already had experience with development for Sony Ericsson/Symbian devices. Thanks.

  • Is there a way to arbitrarily load Resources at runtime in Android?

    - by Omega
    I've got some XML resources in my Android app. Each one has a different name like "bicycle.xml" and "car.xml". I'd like to know if there's a way to load resources based on conditions during run time. As an example... Say I had a text input in my app. When the user enters "bicycle", my app can look up an XML resource by that name, parse and load it. Whereas if they enter "car", they would end up with the data from the other XML file. I've noticed so far that to load resources, you have to use the autogenerated "R" class, which restricts you to hard-coding resources at compile time.

  • Validating a date with symfony using sfValidatorSchema

    - by aaronfalloon
    I'm using the following widget to allow a user to input a date $this->widgetSchema['first_registration'] = new sfWidgetFormDate(array( 'format' => '%month%/%year%', 'years' => range(date('Y', time()) - 15, date('Y', time()) + 15) )); The default format for a date using this widget is %month%/%day%/%year% and so that's what the default validator for this widget checks for. However, I've attempted to alter the validator... $this->validatorSchema['first_registration'] = new sfValidatorDate(array( 'date_format' => '%month%/%year%', 'with_time' => false )); This isn't working and I'm still getting an invalid error. Does anybody know why?

  • How can I fake sql data while preserving statements without commenting my server-side code?

    - by Fedor
    I have to use hardcoded values for certain fields because at this moment we don't have access to the real data. When we do get access, I don't want to go through a lot of work uncommenting. Is it possible to keep this statement the way it is, except use '25' as the alias for ratecode? IF(special.ratecode IS NULL, br.ratecode, special.ratecode) AS ratecode, I have about 8 or so IF statements similar to this and I'm just too lazy ( even with vim ) to re-append while commenting out each if statement line by line. I would have to do this: $sql = 'SELECT u.*,'; // IF ( special.ratecode IS NULL, br.ratecode, special.ratecode) AS ratecode $sql.= '25 AS ratecode';

  • Calculate difference in days ActiveSupport:TimeWithZone in the most "rubyish" style?

    - by Nick
    I have a feeling someone is going to point me to another question that answers this but I've been searching with no luck over this simple issue. I have a Activerecord with a datetime property. It returns as an ActiveSupport:TimeWithZone. I know I can't compare that to DateTime.now because that doesn't include a zone so I need to use Time.zone. Makes sense. What I'm wondering is stylewise is there a "cleaner" way to do this than subtracting and dividing the result by 86400? Here's what I do: ((Time.zone.now - myActiveRecord.visit_date)/86400).to_i Works but seems un-rubyish and I feel like I'm missing something. Should I be casting, comparing or converting some other route or is this really the typical way to do this in rails? Appreciate any tips or a link to a question that already covers this. Thank you

  • How does * work in Python

    - by Deqing
    Just switched from C++ to Python, and found that sometimes it is a little hard to understand ideas behind Python. I guess, a variable is a reference to the real object. For example, a=(1,2,5) meaning a - (1,2,5), so if b=a, then b and a are 2 references pointing to the same (1,2,5). It is a little like pointers in C/C++. If I have: def foo(a,b,c): print a,b,c a=(1,3,5) foo(*a) What does * mean here? Looks like it expands tuple a to a[0], a[1] and a[2]. But why print(*a) is not working while print(a[0],a[1],a[2]) works fine?
