  • Problems with Routing URLs using CGI and Bottle.py

    - by Risingson
    I've been having difficulty getting anything more than a simple index / to return correctly using bottle.py in a CGI environment. When I try to return /hello I get a 404 response. However, if I request /index.py/hello import bottle from bottle import route @route('/') def index(): return 'Index' @route('/hello') def hello(): return 'Hello' if __name__ == '__main__': from wsgiref.handlers import CGIHandler CGIHandler().run(bottle.default_app()) And here is my .htaccess file DirectoryIndex index.py <ifmodule mod_rewrite.c=""> RewriteEngine on RewriteBase / RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ /index.py/$1 [L] </ifmodule> I copied much of the code from here as I'm using DH and it seemed relevant: http://blog.coderonfire.com/2010/02/running-bottle-python-micro-framework.html Thanks for helping.

  • PHP on Windows: Apache or IIS7?

    - by josecortesp
    Here's the thing: Due to a new project, I have to learn PHP from scratch. I'm now in windows and I DON'T want to change quickly, so, don't tell me to change. I need to setup a DreamWeaverCS4/PHP5 develop environment, and, I don't have a clue whether to use Apache or IIS7. I just need some advice relating to it. Remarks: I really don't care about performance(yet), neither portability, and so on. I just need to set it up quickly and easily. Thanks in advance

  • Is preg_match safe enaught in input satinization?

    - by DaNieL
    Im building a new web-app, LAMP environment... im wondering if preg_match can be trusted for user's input validation (+ prepared stmt, of course) for all the text-based fields (aka not html fields; phone, name, surname, etc..). For example, for a classic 'email field', if i check the input like: $email_pattern = "/^([a-zA-Z0-9_\-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)" . "|(([a-zA-Z0-9\-]+\.)+))([a-zA-Z]{2,4}" . "|[0-9]{1,3})(\]?)$/"; $email = $_POST['email']; if(preg_match($email_pattern, $email)){ //go on, prepare stmt, execute, etc... }else{ //email not valid! do nothing except warn the user } can i sleep easy against the sql/xxs injection? I write the regexp to be the more restrictive as they can.

  • 2 listbox to exchange value with DBML

    - by Garcia Julien
    Hi, i'have two Listbox. the think is i do the transfert like : click on field in the left listbox, hit "move right" button and it wll display in the right list box.' The other think it's the first Listbox is bind on Dataset and the second on Entity (Linq-to sql). So when i click on the move next i do that : Dim newSite As New List(Of vw_SiteList) For Each row As SitesDataset.FDDSTRow In SiteAdsListBox.SelectedItems newSite.Add(New vw_SiteList With { _ .SITECODE = row.DEST_COD, _ .SiteDisplay = row.SiteDisplay, _ .CREATEDBY = Environment.GetEnvironmentVariable("USERNAM"), _ .DATECREATED = Now _ }) Next JCDataContext.vw_SiteLists.InsertAllOnSubmit(NewSite) I would like to see now the new field in the right listbox but it isn't there because the field itr's not yet added in the database. How can i do that? Thanks Ju

  • How to parse AMF data in Ruby?

    - by Matchu
    So I see that there are a few Rails plugins for serving AMF. However, is there a library that I can use in a Ruby environment to act as an AMF client: to read AMF data, and deserialize it into a Ruby object? If not, how could I best go about using tools built in other languages? I suppose I could write something in Python or Java or whatever, and call it from Ruby directly via backticks... but I'd first like to ensure that there isn't really any better option. Thanks!

  • Using OpenSessionInViewInterceptor with Hibernate and JSF 2

    - by sammy
    I'm building an application in Hibernate, Spring and JSF2 using only annotations. How can I take advantage of OpenSessionInViewInterceptor found in Spring to catch any hibernate session that might open within a bean? I'm trying to elegantly solve the common “failed to lazily initialize a collection of role: your.Class.assocation no session or session was closed.” problem when trying to read from a yet uninitialized list of POJOs inside another POJO (A Tag entity retrieved by a DAO that contains a List of Project objects I want to read). I've found this: http://www.paulcodding.com/blog/2008/01/21/using-the-opensessioninviewinterceptor-for-spring-hibernate3/ but failed to make use of it in my environment. Please provide a detailed answer, as the Internet is full of foggy, unhelpful tutorials. I'll also be greatful for an alternative solution, given a step-by-step instruction is provided.

  • Rails Action and Fragment Caching during Development?

    - by viatropos
    I'm just starting to get into Rails caching and am wondering how to test whether or not caching is working in my development environment. I have set these two config variables for both the development (temporarily) and production environments: config.action_controller.perform_caching = true config.action_controller.page_cache_directory = File.join(RAILS_ROOT, 'public', 'cache') And my controller basically looks like this (using the resource_controller gem): class EventsController < Spree::BaseController resource_controller caches_page :index index.response do |format| format.html format.xml { render :xml => @collection.to_xml } end # ... end If I do that, I get these files: public/cache/events.html public/cache/events.xml But when I change caches_page to caches_action, I don't see any generated files and am not sure how to tell if the response has been cached. What do I need to know to know that this is working? I've read the docs and related, the rails caching guides, the railscast, and a few other docs, but I'm still wondering where everything is stored. Thanks!

  • Explain Python extensions multithreading

    - by Checkers
    Python interpreter has a Global Interpreter Lock, and it is my understanding that extensions must acquire it in a multi-threaded environment. But Boost.Python HOWTO page says the extension function must release the GIL and reacquire it on exit. I want to resist temptation to guess here, so I would like to know what should be GIL locking patterns in the following scenarios: Extension is called from python (presumably running in a python thread). And extension's background thread calls back into Py_* functions. And a final question is, why the linked document says the GIL should be released and re-acquired?

  • IWshShortcut Target Resolution in Windows 7

    - by Dan Walker
    I've got some code to read shortcuts using the Windows Script Host, but it appears to have a problem in Windows 7. When reading shortcuts, if there is an environment variable in the target path, it resolves to the wrong drive. For example, the shortcut to Notepad resolves to D:\Windows\system32\notepad.exe instead of C:\Windows\system32\notepad.exe. The problem is not with my computer's settings, because the shortcut works just fine, and when looking at the value for %SystemRoot%, it shows C:\Windows. Any ideas as to what could be the problem, or alternatively, what a different method of reading shortcuts would be? Thanks, Dan

  • Monitoring pthread context switching

    - by simon
    I would like to monitor the the context switching behavior in a multi-threaded pthread application. In other RTOSes(Micro C OS) I have been able to register a context switch callback for each thread in the application, and then log (or toggle a gpio) and watch the thread context switching in real time. This was a valuable tool for debugging the real time behavior and interaction of the multiple threads. My current environment is embedded linux utilizing the pthread api. Is there a way to montior each of the context switches?

  • Changing postgres user password in a master-slave setup

    - by NRS
    We have PITR setup and WAL shipping enabled. We would like to change the password for the user postgres. The process is simple enough. However, since we cannot connect to the SLAVE how would we make sure all passwords are in synch? Would temporarily disabling WAL shipping allow me to connect to the slave to change the password there? I cant seem to find documentation on a clean way to implement this password change and I don't have a test environment.

  • Silverlight 4 - encoding PCM data from the microphone

    - by Richard
    Hi I've written a basic SL4 application to capture audio data from the microphone using CaptureSource. The trouble is, it's raw PCM output - which means huge and uncompressed. Given that I need this application to run purely within a SL4 environment, how can I compress the PCM audio data into something that can be delivered to a remote server more easily? In conversation, people have suggested Speex and WMA for instance, but I haven't found any libraries or examples that work without requiring reference to DLL's that won't work in a SL4 project. Thanks, Richard.

  • ORM in the realworld

    - by josh
    I am begining a new project that i think will last for some years. Am in the point of deciding the ORM framework to use (or whether to use one at all). Can anyone with experience tell me whether orm frameworks are used in realworld applications. The problem i have in mind is this: The orm tool will generate for me tables and columns etc as i create and modify my entities. However, after the project has gone live and is in production, certain database changes will not be possible. Can this hinder the advancement of the project. If i had used a framework like ibatis for example, i know i would only need to adjust the sql statements based on the database changes. Can someone tell me whether ORM tools have survived the live environment. At my office, we use java based ERP that was done long ago and it was never done using any ORM framework. Regards. Josh

  • I need git-svn to act as a Subversion v1.5+ client

    - by Ben Ward
    I'm running git 1.7 on Mac OSX, installed via Homebrew. I'm trying to use git svn to work with a Subversion server that requires Subversion 1.5 clients (a restriction enforced via a pre-commit hook.) Running git svn --version reveals that as far as git is concerned, git svn is equivalent to svn v1.4.4. I can't establish whether git svn is a total clone of subversion, and thus needs to be updated to meet subversion v1.5 functionality, or if git is compiled against or just points to some version of subversion under the hood. I've struggled finding anyone else trying to upgrade the version of git-svn, and I'm guessing this client version restriction is unusual, but I'm stuck with it (corporate environment.) Is it possible to have git operate as svn 1.5?

  • .NET Active Directory Password Expiration on Windows 2008

    - by Brent Pabst
    Searched SO and Everywhere else, including the .net developers guide to directory services programming book - no luck. I am trying to create a simple password reset web page that allows the user to change their password. The change password portion of the code is working fine. For the users I would also like to display when their current password will expire next. Using the sample code from the book mentioned above I was able to get all of the code setup however, the attribute that is returned is always equal to Long.MinValue and hence cannot be inverted to a positive number, plus this means it did not find the proper domain setting. Does anyone have sample code or references for getting the password expiration in a Windows 2008 or R2 domain environment where password policies can be different for each user?

  • problem with two .NET threads and hardware access

    - by mack369
    I'm creating an application which communicates with the device via FT2232H USB/RS232 converter. For communication I'm using FTD2XX_NET.dll library from FTDI website. I'm using two threads: first thread continuously reads data from the device the second thread is the main thread of the Windows Form Application I've got a problem when I'm trying to write any data to the device while the receiver's thread is running. The main thread simply hangs up on ftdiDevice.Write function. I tried to synchronize both threads so that only one thread can use Read/Write function at the same time, but it didn't help. Below code responsible for the communication. Note that following functions are methods of FtdiPort class. Receiver's thread private void receiverLoop() { if (this.DataReceivedHandler == null) { throw new BackendException("dataReceived delegate is not set"); } FTDI.FT_STATUS ftStatus = FTDI.FT_STATUS.FT_OK; byte[] readBytes = new byte[this.ReadBufferSize]; while (true) { lock (FtdiPort.threadLocker) { UInt32 numBytesRead = 0; ftStatus = ftdiDevice.Read(readBytes, this.ReadBufferSize, ref numBytesRead); if (ftStatus == FTDI.FT_STATUS.FT_OK) { this.DataReceivedHandler(readBytes, numBytesRead); } else { Trace.WriteLine(String.Format("Couldn't read data from ftdi: status {0}", ftStatus)); Thread.Sleep(10); } } Thread.Sleep(this.RXThreadDelay); } } Write function called from main thread public void Write(byte[] data, int length) { if (this.IsOpened) { uint i = 0; lock (FtdiPort.threadLocker) { this.ftdiDevice.Write(data, length, ref i); } Thread.Sleep(1); if (i != (int)length) { throw new BackendException("Couldnt send all data"); } } else { throw new BackendException("Port is closed"); } } Object used to synchronize two threads static Object threadLocker = new Object(); Method that starts the receiver's thread private void startReceiver() { if (this.DataReceivedHandler == null) { return; } if (this.IsOpened == false) { throw new BackendException("Trying to start listening for raw data while disconnected"); } this.receiverThread = new Thread(this.receiverLoop); //this.receiverThread.Name = "protocolListener"; this.receiverThread.IsBackground = true; this.receiverThread.Start(); } The ftdiDevice.Write function doesn't hang up if I comment following line: ftStatus = ftdiDevice.Read(readBytes, this.ReadBufferSize, ref numBytesRead);

  • Query and/or Search for SharePoint Document ID

    - by Paul-Jan
    We have the sharepoint 2010 environment with Document ID's enabled. Given (part of) a Doc ID, we want to programmatically retrieve the document(s) matching that ID. The problem seems to be that this column is rather special, in that it might need special handling. Using an SPSiteDataQuery, fetching the _dlc_DocId field as part of the viewfields works fine. However, including it as part of the where query never results in any documents being fetched. Using the Search API has gotten us nowhere at all. Has anyone pulled this off, or any suggestions on how to tackle this problem? [Update] Looks like DocumentIdProvider.GetDocumentUrlsById might be used for this purpose. If necessary, the matching SPListItem can then be found by querying on the URL. However, the MSDN documentation doesn't document the documentId arugment properly, so I'm unsure whether partial ID's are allowed and in what format.

  • C++ project type: unicode vs multi-byte; pros and cons

    - by Stefan Valianu
    I'm wondering what the Stack Overflow community thinks when it comes to creating a project (thinking primarily c++ here) with a unicode or a multi-byte character set. Are there pros to going Unicode straight from the start, implying all your strings will be in wide format? Are there performance issues / larger memory requirements because of a standard use of a larger character? Is there an advantage to this method? Do some processor architectures handle wide characters better? Are there any reasons to make your project Unicode if you don't plan on supporting additional languages? What reasons would one have for creating a project with a multi-byte character set? How do all of the factors above collide in a high performance environment (such as a modern video game) ?

  • please explain NHibernate HiLo

    - by Ben
    I'm struggling to get my head round how the HiLo generator works in NHibernate. I've read the explanation here which made things a little clearer. My understanding is that each SessionFactory retrieves the high value from the database. This improves performance because we have access to IDs without hitting the database. The explanation from the above link also states: For instance, supposing you have a "high" sequence with a current value of 35, and the "low" number is in the range 0-1023. Then the client can increment the sequence to 36 (for other clients to be able to generate keys while it's using 35) and know that keys 35/0, 35/1, 35/2, 35/3... 35/1023 are all available. How does this work in a web application as don't I only have one SessionFactory and therefore one hi value. Does this mean that in a disconnected application you can end up with duplicate (low) ids in your entity table? In my tests I used these settings: <id name="Id" unsaved-value="0"> <generator class="hilo"/> </id> I ran a test to save 100 objects. The IDs in my table went from 32768 - 32868. The next hi value was incremented to 2. Then I ran my test again and the Ids were in the range 65536 - 65636. First off, why start at 32768 and not 1, and secondly why the jump from 32868 to 65536? Now I know that my surrogate keys shouldn't have any meaning but we do use them in our application. Why can't I just have them increment nicely like a SQL Server identity field would. Finally can someone give me an explanation of how the max_lo parameter works? Is this the maximum number of low values (entity ids in my head) that can be created against the high value? This is one topic in NHibernate that I have struggled to find documentation for. I read the entire NHibernate in action book and it still doesn't go into how this works in any detail. Thanks Ben

  • Best Database Change Control Methodologies

    - by SnapJag
    As a database architect, developer, and consultant, there are many questions that can be answered. One, though I was asked recently and still can't answer good, is... "What is one of, or some of, the best methods or techniques to keep database changes documented, organized, and yet able to roll out effectively either in a single-developer or multi-developer environment." This may involve stored procedures and other object scripts, but especially schemas - from documentation, to the new physical update scripts, to rollout, and then full-circle. There are applications to make this happen, but require schema hooks and overhead. I would rather like to know about techniques used without a lot of extra third-party involvement.

  • Core dump equivalence for Java

    - by m3rLinEz
    So far I have learned about generating thread dump and heap dump using jstack and and jmap respectively. However, jstack thread dump contains only texts describing the stack on each thread. And opening heap dump (.hprof file) with Java VisualVM only shows the objects allocated in the heap. What I actually want is to be able see the stack, to switch to particular stack frame, and watch local variables. This kind of post-mortem debugging can be done normally with tools like WinDbg, gdb and a core file (for a native C++ program.) I wonder if such 'core' file (which will allow me to debug in non-live environment) exists in Java?

  • Database Network Latency

    - by Karl
    Hi All, I am currently working on an n-tier system and battling some database performance issues. One area we have been investigating is the latency between the database server and the application server. In our test environment the average ping times between the two boxes is in the region of 0.2ms however on the clients site its more in the region of 8.2 ms. Is that somthing we should be worried about? For your average system what do you guys consider a resonable latency and how would you go about testing/measuring the latency? Karl

  • Modifying an old Windows program not to call exit after a keypress without source access

    - by rustyn2
    I have an older C++ Windows program that I've been asked to get run in a kiosk style environment for a student project. From the main menu, hitting ESC will exit the program, which is undesirable. In ye olden days I would have trapped the keyboard interrupt or whatever and dug around to NOOP whatever JMP or CALL was getting referenced in the case statement that likely decides all that, but on Windows everything goes through various registered event handlers, and I haven't done any windows internals work in about 10 years. Is there a good tool to breakpoint a program on certain WM_EVENT (WM_KEYDOWN being a prime target) messages or similar, so that I can narrow down where in the executable the check is made? I'm currently stepping back from various potential system calls made before the various thread cleanups and final exit calls but it seems like there has to be a better way to do this that I'm forgetting.
