  • stripe payment issue ruby on rails

    - by Admir Huric
    So I have made a stripe payment option in my app. When I click the button pay now, it shows me that the payment is successful. and when I go to my stripe account and go to stripe-test and check logs, I can see my test payment with the code 200 OK. But this payment doesn't show in stripe-test events, or in stripe-test payments. Are the payments from logs processed the next day or am I doing something wrong? def charge Stripe.api_key = "some_test_api_key" customer = Stripe::Customer.retrieve(stripe_customer_id) if stripe_customer_id.nil? Stripe::Charge.create( :amount => 2500, :currency => "cad", :customer => stripe_customer_id, :description => "Usage charges for #{name}" ) end rescue Stripe::StripeError => e logger.error "Stripe Error: " + e.message errors.add :base, "Unable to process charge. #{e.message}." false end

  • How can I catch a "catchable fatal error" on PHP type hinting?

    - by Ho
    Hello, I am trying to implement Type Hinting of PHP5 on one of my class, class ClassA { public function method_a (ClassB $b) {} } class ClassB {} class ClassWrong{} Correct usage: $a = new ClassA; $a->method_a(new ClassB); producing error: $a = new ClassA; $a->method_a(new ClassWrong); Catchable fatal error: Argument 1 passed to ClassA::method_a() must be an instance of ClassB, instance of ClassWrong given... May I know if it is possible to catch that error(since it says "catchable")? and if yes, how? Thank you.

  • Writing datatable to database file, one record at a time

    - by Kevin
    I want to write a C# program that will read a row from a datatable (named loadDT) and update a database file (named Forecasts.mdb). My datatable looks like this (each day's value is a number representing kilowatts usage forecast): Hour Day1 Day2 Day3 Day4 Day5 Day6 Day7 1 519 520 524 498 501 476 451 My database file looks like this: Day Hour KWForecast 1 1 519 2 1 520 3 1 524 ... and so on. Basically, I want to be able to read one row from the datatable, and then extrapolate that out to my database file, one record at a time. Each row from the datatable will result in seven records written to the database file. Any ideas on how to go about this? I can connect to my database, the connection string works, and I can update and delete from the database. I just can't wrap my head around how to do this one record at a time.

  • What makes you want to learn Common Lisp? What do you want from it?

    - by JasonFruit
    I'm working on a toolkit (sort of a live-CD Lisp-in-a-Box) for people new to Common Lisp, and I want to make sure it is broadly satisfying. What is attractive to you about Lisp? What do/did/would you need to get you started and keep you interested? What I have so far: SBCL 10.22, Emacs 22.3, SLIME, and LTK bundled together and configured on a Linux live-CD that boots entirely to RAM. I've now released the result of this; it is available at the Thnake website.

  • Why implement DB connection pointer object as a reference counting pointer? (C++)

    - by DVK
    At our company one of the core C++ classes (Database connection pointer) is implemented as a reference counting pointer. To be clear, the objects are NOT DB connections themselves, but pointers to a DB connection object. The library is very old, and nobody who designed is around anymore. So far, nether I, nor any C++ experts in the company that I asked have come up with a good reason for why this particular design was chosen. Any ideas? It is introducing some problems (partially due to awful reference pointer implementation used), and I'm trying to understand if this design actually has some deep underlying reasons? The usage pattern these days seems to be that the DB connection pointer object is returned by a DB connection manager class, and it's somewhat unclear whether DB connection pointers were designed to be able to be used independently of DB connection manager.

  • What good software or scripts are available for managing users and subscriptions on our website?

    - by undefined
    hi all, Ok so it's not exactly a programing question but does anyone know or have experience with looking for a system for managing users on a website we are building? what is the shortlist of good feature rich secure solutions. we need Php and mysql integration and payment support for main credit cards. We will also want to be able to track users and generate reports about usage, subscription etc, create and send batch emails etc. It would also be great to have the ability to integrate customer support with this so we can view support tickets raised by users. cheers we are running PHP, mysql on an IIS server

  • Program seems to get stuck ?

    - by Frank
    I have a Java program, I did some change and the strange thing is no matter what I do now, it will output the same result before my change, I looked into my system (Windows Vista), and clicked on "Generate a system health report", the result says : Symptom : A service is reported as having an unexpected error code Cause : One or more services has failed. The service did not stop gracefully, suggesting the service may have crashed or one of its components stopped in an unsupported way. Details : Service exited with code not equal to 0 or 1077 Resolution : Restart the service It doesn't say which service, and I defragmented my drives a few times, it still gave me the same report. I also checked my memory, it says no problem with ram. Everything else is ok, I re-started the windows a few times, got more free space on my C: drive, yet the Java program is still not responding to my new changes, unless I intentionally make a mistake, it gives me compile error, but if it can compile successfully, it still gives me the results before the change. What can I do to fix this ? Frank

  • .Net OutOfMemory on Server but not Desktop

    - by Jörg Battermann
    Is it possible that the .Net framework behaves differently when it comes to garbage collection / memory limitations on server environments? I am running explicitly x86 compiled apps on a 64bit server machine with 32gbs of physical ram and I am running out of memory (SystemOutOfMemoryException) even though nothing but that particular app is running and the server/all other apps utilize 520mb total.. but I cannot reproduce that behaviour on my own (client win7) machine. Now I know that the app -is- memory intensive, but why is it causing problems on the server and not on the client?

  • Multi-process builds in Visual Studio 2010: Worth it?

    - by coryr
    I've started testing our C++ software with VS2010 and the build times are really bad (30-45 minutes, about double the VS2005 times). I've been reading about the /MP switch for multi-process compilation. Unfortunately, it is incompatible with some features that we use quite a bit like #import, incremental compilation, and precompiled headers. Have you had a similar project where you tried the /MP switch after turning off things like precompiled headers? Did you get faster builds? My machine is running 64-bit Windows 7 on a 4 core machine with 4 GB of RAM and a fast SSD storage. Virus scanner disabled and a pretty minimal software environment.

  • Are there any C++ tools that detect misuse of static_cast, dynamic_cast, and reinterpret_cast?

    - by chrisp451
    The answers to the following question describe the recommended usage of static_cast, dynamic_cast, and reinterpret_cast in C++: http://stackoverflow.com/questions/332030/when-should-static-cast-dynamic-cast-and-reinterpret-cast-be-used Do you know of any tools that can be used to detect misuse of these kinds of cast? Would a static analysis tool like PC-Lint or Coverity Static Analysis do this? The particular case that prompted this question was the inappropriate use of static_cast to downcast a pointer, which the compiler does not warn about. I'd like to detect this case using a tool, and not assume that developers will never make this mistake.

  • glDrawElements allocating memory and not releasing it

    - by Joshua Weinberg
    Using OpenGLES 1.1 on the iPhone 3G (device, not simulator), I do normal drawing fun. But at points during the run of the application I get giant memory spikes, after a lot of digging with instruments I have found that it is glDrawElements that is grabbing the memory. The buffer being allocated is 4 meg, which to me means its loading a texture into RAM, which I guess could be valid, but its never releasing this buffer, and is allocating multiple of them. How do I make sure that these buffers that GL is creating get destroyed, instead of just hanging around?

  • How to reliably measure available memory in Linux?

    - by Alex B
    Linux /proc/meminfo shows a number of memory usage statistics. MemTotal: 4040732 kB MemFree: 23160 kB Buffers: 163340 kB Cached: 3707080 kB SwapCached: 0 kB Active: 1129324 kB Inactive: 2762912 kB There is quite a bit of overlap between them. For example, as far as I understand, there can be active page cache (belongs to "cached" and "active") and inactive page cache ("inactive" + "cached"). What I want to do is to measure "free" memory, but in a way that it includes used pages that are likely to be dropped without a significant impact on overall system's performance. At first, I was inclined to use "free" + "inactive", but Linux's "free" utility uses "free" + "cached" in its "buffer-adjusted" display, so I am curious what a better approach is. When the kernel runs out of memory, what is the priority of pages to drop and what is the more appropriate metric to measure available memory?

  • Wolfram Workbench and Mathematica Help System

    - by belisarius
    I find the Wolfram Workbench a nice environment for Mathematica development. However, as I program in Mathematica, I need to navigate the Help System very often. The Workbench provides a tooltip tool that shows a very basic help for the Mma functions (just the usage messages), and is not enough for my usual needs. So: Is there a way to bring up and navigate the whole Mma Help System from inside the Workbench? Alternative solutions are also welcome. Re-entering the function name in a notebook and pressing F1 is not :)

  • Parsing getopts in bash

    - by ABach
    I've got a bash function that I'm trying to use getopts with and am having some trouble. The function is designed to be called by itself (getch), with an optional -s flag (getch -s), or with an optional string argument afterward (so getch master and getch -s master are both valid). The snippet below is where my problem lies - it isn't the entire function, but it's what I'm focusing on: getch() { if [ "$#" -gt 2 ] || [ "$1" = "-h" ] || [ "$1" = "--help" ]; then echo "Usage: $0 [-s] [branch-name]" >&2 return 1 fi while getopts "s" opt; do echo $opt # This line is here to test how many times we go through the loop case $opt in s) squash=true shift ;; *) ;; esac done } The getch -s master case is where the strangeness happens. The above should spit out s once, but instead, I get this: [user@host:git-repositories/temp]$ getch -s master s s [user@host:git-repositories/temp]$ Why is it parsing the -s opt twice?

  • Is it valid syntax to have ordered and unordered lists in sequence in markdown?

    - by nfm
    I just wrote some markdown and it doesn't seem to render correctly. Is it legal syntax to have an ordered list, followed by newlines, then followed by an unordered list? Or is this a bug in bluecloth? For example: 1. One 2. Two 3. Three * Apple * Banana * Carrot Bluecloth creates a single <ul> and nests apple, banana and carrot as <li>'s under it. Stackoverflow's markdown parser does this too. Am I just doing it wrong? Surely this is a common usage case...

    How to find the site performance, there is a tools like YSLOW, Speed traker in google that shows the speed of the website. I have done a php project on LMS with Zend Framework, Everything is in live. When user post contents for a subject that may be size 200K and submitted to the server takes too slow. Sometime server may get DOWN. I login to server(PUTTY) and checked i found that there is more resource occupied in my server. It uses full memory on the server. When i cleared the resource the site loads well. Site is in Dedicated server with 3 more domains with 4GB Ram. Because of this LMS website all the website gets down. I need to check what is wrong in my website. How do i Start?

  • Is It Possible To Spring Autowire the same Instance of a protoype scoped class in two places

    - by Mark
    Hi ** changed the example to better express the situation i am using spring 2.5 and have the following situation @Component @Scope("prototype") Class Foo { } class A { @Autowired Foo fooA; } class B { @Autowired Foo fooB; } class C { @Autowired Foo fooC; } i am trying to understand if there is some way to use @Autowired and bind the same instance of FOO onto fooA and fooB while binding a different instance to fooC i understand that if the scope of FOO will be singleton it will work but i am wandering if there is a way to achieve the same goal while using a protoype scope. also please explain is this the correct usage of the autowiring concept ? am i trying to abuse the spring framework purpose

  • MySQL ALTER TABLE on very large table - is it safe to run it?

    - by Timothy Mifsud
    I have a MySQL database with one particular MyISAM table of above 4 million rows. I update this table about once a week with about 2000 new rows. After updating, I then perform the following statement: ALTER TABLE x ORDER BY PK DESC i.e. I order the table in question by the primary key field in descending order. This has not given me any problems on my development machine (Windows with 3GB memory), but, even though 3 times I have tried it successfully on the production Linux server (with 512MB RAM - and achieving the resulted sorted table in about 6 minutes each time), the last time I tried it I had to stop the query after about 30 minutes and rebuild the database from a backup. I have started to wonder whether a 512MB server can cope with that statement (on such a large table) as I have read that a temporary table is created to perform the ALTER TABLE command?! And, if it can be safely run, what should be the expected time for the alteration of the table? Thanks in advance, Tim

  • Is Webhooks a style/pattern or a specification?

    - by Emilio
    I've been reading about Webhooks and I'm trying to determine if it's a specification vs a style/pattern. By "specification" I mean that the implementation details, e.g. headers, payload and so on are well defined. By "style" or "pattern" I mean in the sense that REST is a style (as opposed to a spec) or a pattern which describes usage but doesn't define implementation details. From what I see, Webhooks is a style/pattern. That the event(s) which triggers the http callbacks are generated however the developer wants, and that the http callbacks have no specific implementation requirements except to be an http post. Is this correct?

  • Database design: Using hundred of fields for little values

    - by user964260
    I'm planning to develop a PHP Web App, it will mainly be used by registered users(sessions) While thinking about the DB design, I was contemplating that in order to give the best user experience possible there would be lots of options for the user to activate, deactivate, specify, etc. For example: - Options for each layout elements, dialog boxes, dashboard, grid, etc. - color, size, stay visible, invisible, don't ask again, show everytime, advanced mode, simple mode, etc. This would get like 100s of fields ranging from simple Yes/No or 1 to N values..., for each user. So, is it having a field for each of these options the way to go? or how do those CRMs or CMS or other Web Apps do it to store lots of 1-2 char long values? Do they group them on Text fields separated by a special char and then "explode" them as an array for runtime usage? thank you

  • Recreation of DB using "mysql mydb < mydb.sql" is really slow when the table has tens of millions of

    - by Jian Lin
    It seems that a MySQL database that has a table with tens of millions of records will get a big INSERT INTO statement when the following mysqldump some_db > some_db.sql is done to back up the database. (is it 1 insert statement that handles all the records?) So when reconstructing the DB using mysql some_db < some_db.sql then the CPU is hardly busy (about 1.8% usage by the mysql process... I don't see a mysqld either?) and also the hard disk doesn't seem to be too busy... Last time, the whole restore process took 5 hours. Is there a way to make it faster? Such as, when doing mysqldump, can it break the INSERT statement into shorter ones, so that the mysql doesn't need to parse the line so hard when restoring the DB?

  • Does a program exist for checking two similar directories for file differences?

    - by John Sullivan
    Is there a program to compare one folder and all subfolders to another folder and all subfolders for differences in the files contained therein (presence, absence of files, size and list of filenames)? Example of usage: I have 100 DLL files from environment 1 and I want to check if any of them are different (in size and date modified) from the 100 DLL files in environment 2. So I copy and paste all the DLLs in environment 1 into directory A, and all the DLLs in environment 2 into directory B. I then run my "directory comparison" program on directories A and B and find out that, aha, here is a list of 7 DLLs that have different modified dates and times between the two directories. EDIT: OS is windows XP

  • Uses for static generic classes?

    What are the key uses of a Static Generic Class in C#? When should they be used? What examples best illustrate their usage? e.g. public static class Example<T> { public static ... } Since you can't define extension methods in them they appear to be somewhat limited in their utility. Web references on the topic are scarce so clearly there aren't a lot of people using them.

  • jQuery.keypad Performance Issues

    - by John Duff
    I am working on a Kiosk Touch Screen application and using the JQuery.keypad plugin and noticing some major performance issues. If you click a number of buttons in rapid succession the CPU gets pegged, the button clicks don't keep up with the clicking and some button presses even get lost. On my dev machine this isn't as noticeable, but on the Kiosk itself with 1 gig of ram it's painful. Trying the demo keypad at http://keith-wood.name/keypad.html#inline the one with multiple targets (which is the case with mine) has the exact same issues. Does anyone have any suggestions on how we might be able to improve this? The Kiosk runs in Firefox only so something specific to that would work. I'm using v1.2.1 of jquery.keypad and just upgraded to v1.4.2 of jquery.
