  • Connecting my flex application to Restlet webservices

    - by Vatsala
    Hi, I am doing some trial testing awith Amazon ec2 boxes, deploying flex apps running on top of restlet powered webservices. I have this problem - Everytime i deploy the app to the cloud, I'm having to hardcode the IP address of the server into the ActionScript/MXML files (http://72.93.48.39:8080/xxx/abc/) and for certain reasons, i am forced to choose a different IP everytime. and i think its really not the right way to deploy the application. I would like to know what other people do in such scenarios? On thinking about it, i thought i could make it pickup values from the HTMLVars of the HTML wrapper. but that again has to be edited everytime again and again. will it be possible to be able to supply these values : server's ip address, server's port number(in case its not 8080 on some machine) at build time? if so can anyone give me a barbones sample build.xml just as an example?

  • Why is 'heroku create' doing nothing?

    - by vlasits
    I opened a heroku account. I followed the instructions on http://docs.heroku.com/quickstart. I have a working rails app which I have deployed successfully elsewhere. I have a github account that works. I have a local git repository for my rails app. I installed the heroku gem. It shows up in my gem list. I typed 'heroku create' at the command prompt... My command console showed that it was thinking about it, but did nothing. No errors. No action. Possible related facts: I am using a Windows 7 machine. I have also failed miserably at deploying with capistrano with a similar--issue command, get no response--pattern.

  • Errors detected when loading a vim plugin from .vimrc

    - by Tejinder
    I have installed vim 7.3 on debian system along with some vimrc i have downloaded from internet. It used to work fine on my other debian machine but here i get these error messages while i load the vim editor.

  • Installing CakePHP on Windows with Apache

    - by GeoSQL
    Hi, I'm trying to install CakePHP on my Windows XP machine running Apache 2.2. I have installed the Cake folder in my doc root. I've read the installation instructions that say to include this line in the httpd.conf file; <Directory /path/to/cake> Does anyone know how to translate that into Windows? I currently have the following in my conf file: <Directory "C:/Apache/Apache2.2/htdocs/cakeapp/"> Whenever I uncomment this line it crashes Apache. I've tried switching the slashes to "\" and I tried taking the slash off the end. Any advice? Thanks

  • code throws std::bad_alloc, not enough memory or can it be a bug?

    - by Andreas
    I am parsing using a pretty large grammar (1.1 GB, it's data-oriented parsing). The parser I use (bitpar) is said to be optimized for highly ambiguous grammars. I'm getting this error: 1terminate called after throwing an instance of 'std::bad_alloc' what(): St9bad_alloc dotest.sh: line 11: 16686 Aborted bitpar -p -b 1 -s top -u unknownwordsm -w pos.dfsa /tmp/gsyntax.pcfg /tmp/gsyntax.lex arbobanko.test arbobanko.results Is there hope? Does it mean that it has ran out of memory? It uses about 15 GB before it crashes. The machine I'm using has 32 GB of RAM, plus swap as well. It crashes before outputting a single parse tree. The parser is an efficient CYK chart parser using bit vector representations; I presume it is already near the limit of memory efficiency. If it really requires too much memory I could sample from the grammar rules, but this will decrease parse accuracy of course.

  • Speakers, Please Check Your Time

    - by AjarnMark
    Woodrow Wilson was once asked how long it would take him to prepare for a 10 minute speech. He replied "Two weeks". He was then asked how long it would take for a 1 hour speech. "One week", he replied. 2 hour speech? "I'm ready right now," he replied.  Whether that is a true story or an urban legend, I don’t really know, but either way, it is a poignant reminder for all speakers, and particularly apropos this week leading up to the PASS Community Summit. (Cross-posted to the PASS Professional Development Virtual Chapter blog #PASSProfDev.) What’s the point of that story?  Simply this…if you have plenty of time to do your presentation, you don’t need to prepare much because it is easy to throw in more and more material to stretch out to your allotted time.  But if you are on a tight time constraint, then it will take significant preparation to distill your talk down to only the essential points. I have attended seven of the last eight North American Summit events, and every one of them has been fantastic.  The speakers are great, the material is timely and relevant, and the networking opportunities are awesome.  And every year, there is one little thing that just bugs me…speakers going over their allotted time.  Why does it bother me so?  Well, if you look at a typical schedule for a Summit, you’ll see that there are six or more sessions going on at the same time, and only 15 minutes to move from one to another.  If you’re trying to maximize your training dollar by attending something during every session time slot, and you don’t want to be the last guy trying to squeeze into the middle of the row, then those 15 minutes can be critical.  All the more so if you need to stop and use the bathroom or if you have to hike to the opposite end of the convention center.  It is really a bad position to find yourself having to choose between learning the last key points of Speaker A who is going over time, and getting over to Speaker B on time so you don’t miss her key opening remarks. And frankly, I think it is just rude.  Yes, the speakers are the function, after all they are bringing the content that the rest of us are paying to learn.  But it is also an honor to be given the opportunity to speak at a conference like this, and no one speaker is so important that the conference would be a disaster without him.  Speakers know when they submit their abstract, long before the conference, how much time they will have.  It has been the same pattern at the Summit for at least the last eight years.  Program Sessions are 75 minutes long.  Some speakers who have a good track record, and meet other qualifying criteria, are extended an invitation to present a Spotlight Session which is 90 minutes (a 20% increase).  So there really is no excuse.  It’s not like you were promised a 2-hour segment and then discovered when you got here that it was only 75 minutes.  In fact, it’s not like PASS advertised 90-minute sessions for everyone and then a select few were cut back to only 75.  As a speaker, you know well before you get here which type of session you are doing and how long it is, so as a professional, you should plan accordingly. Now you might think that this only happens to rookies, but I’ll tell you that some of the worst offenders are big-name veterans who draw huge attendance numbers for their sessions.  Some attendees blow this off as, “Hey, it’s so-and-so, and I’d stay here for hours and listen to him/her talk.”  To which I would reply, “Then they should have submitted for a pre- or post-conference day-long seminar instead, but don’t try to squeeze your day-long talk into a 90-minute session.”  Now I don’t really believe that these speakers are being malicious or just selfishly trying to extend their time in the spotlight.  I think that most of them are merely being undisciplined and did not trim their presentation sufficiently, or allowed themselves to get off-track (often in a generous attempt to help someone in the audience with a question or problem that really should have been noted for further discussion after the session). So here is my recommendation…my plea, even.  TRIM THE FAT!  Now.  Before it’s too late.  Before you even get on the airplane, take a long, hard look at your presentation and eliminate some of the points that you originally thought you had to make, but in reality are not truly crucial to your main topic.  Delete a few slides.  Test your demos and have them already scripted rather than typing them during your talk.  It is better to cut out too much and end up with plenty of time at the end for Questions & Answers.  And you can always keep some notes on the stuff that you cut out so that you could fill it back in at the end as bonus material if you really do end up with a whole bunch of time on your hands.  But I don’t think you will.  And if you do, that will look even better to the audience as it will look like you’re giving them something extra that not every audience gets.  And they will thank you for that.

  • Custom Memory Allocator for STL map

    - by Prasoon Tiwari
    This question is about construction of instances of custom allocator during insertion into a std::map. Here is a custom allocator for std::map<int,int> along with a small program that uses it: #include <stddef.h> #include <stdio.h> #include <map> #include <typeinfo> class MyPool { public: void * GetNext() { return malloc(24); } void Free(void *ptr) { free(ptr); } }; template<typename T> class MyPoolAlloc { public: static MyPool *pMyPool; typedef size_t size_type; typedef ptrdiff_t difference_type; typedef T* pointer; typedef const T* const_pointer; typedef T& reference; typedef const T& const_reference; typedef T value_type; template<typename X> struct rebind { typedef MyPoolAlloc<X> other; }; MyPoolAlloc() throw() { printf("-------Alloc--CONSTRUCTOR--------%08x %32s\n", this, typeid(T).name()); } MyPoolAlloc(const MyPoolAlloc&) throw() { printf(" Copy Constructor ---------------%08x %32s\n", this, typeid(T).name()); } template<typename X> MyPoolAlloc(const MyPoolAlloc<X>&) throw() { printf(" Construct T Alloc from X Alloc--%08x %32s %32s\n", this, typeid(T).name(), typeid(X).name()); } ~MyPoolAlloc() throw() { printf(" Destructor ---------------------%08x %32s\n", this, typeid(T).name()); }; pointer address(reference __x) const { return &__x; } const_pointer address(const_reference __x) const { return &__x; } pointer allocate(size_type __n, const void * hint = 0) { if (__n != 1) perror("MyPoolAlloc::allocate: __n is not 1.\n"); if (NULL == pMyPool) { pMyPool = new MyPool(); printf("======>Creating a new pool object.\n"); } return reinterpret_cast<T*>(pMyPool->GetNext()); } //__p is not permitted to be a null pointer void deallocate(pointer __p, size_type __n) { pMyPool->Free(reinterpret_cast<void *>(__p)); } size_type max_size() const throw() { return size_t(-1) / sizeof(T); } void construct(pointer __p, const T& __val) { printf("+++++++ %08x %s.\n", __p, typeid(T).name()); ::new(__p) T(__val); } void destroy(pointer __p) { printf("-+-+-+- %08x.\n", __p); __p->~T(); } }; template<typename T> inline bool operator==(const MyPoolAlloc<T>&, const MyPoolAlloc<T>&) { return true; } template<typename T> inline bool operator!=(const MyPoolAlloc<T>&, const MyPoolAlloc<T>&) { return false; } template<typename T> MyPool* MyPoolAlloc<T>::pMyPool = NULL; int main(int argc, char *argv[]) { std::map<int, int, std::less<int>, MyPoolAlloc<std::pair<const int,int> > > m; //random insertions in the map m.insert(std::pair<int,int>(1,2)); m[5] = 7; m[8] = 11; printf("======>End of map insertions.\n"); return 0; } Here is the output of this program: -------Alloc--CONSTRUCTOR--------bffcdaa6 St4pairIKiiE Construct T Alloc from X Alloc--bffcda77 St13_Rb_tree_nodeISt4pairIKiiEE St4pairIKiiE Copy Constructor ---------------bffcdad8 St13_Rb_tree_nodeISt4pairIKiiEE Destructor ---------------------bffcda77 St13_Rb_tree_nodeISt4pairIKiiEE Destructor ---------------------bffcdaa6 St4pairIKiiE ======Creating a new pool object.

Why is this necessary? Is there a way to suppress this? Thanks! Edit: This code tested on x86 machine with g++ version 4.1.2. If you wish to run it on a 64-bit machine, you'll have to change at least the line return malloc(24). Changing to return malloc(48) should work.

  • Why does Perl's Crypt::SSLeay timeout on Intel Mac OS X machines?

    - by Joe
    A have a Perl cron job that recently started having its HTTPS connections start failing with an error of "500 SSL read timeout". I've tracked that the error is being thrown as part of an alarm in Crypt::SSLeay, but I don't know if this is simply something taking too long to respond. So far, I've adjusted the timeout from the default 30 seconds to 10 minutes and it still times out. I've moved the script to other machines, and those on Intel Mac OS X systems all time out, while those under Linux, or on PPC Mac OS X systems run fine, so I don't think it's changes on the network or remote server. When the process started having problems does not coincide with any software updates or reboots on the machine, and I've contacted the server I'm connecting to, and everyone claims that they haven't changed anything. Does anyone have recommendations on trying to debug HTTPS, or have you ever seen this behavior and give recommendations on something I might've overlooked at that could've caused this problem?

  • Speeding up PostgreSQL query where data is between two dates

    - by Roger
    I have a large table ( 50m rows) which has some data with an ID and timestamp. I need to query the table to select all rows with a certain ID where the timestamp is between two dates, but it currently takes over 2 minutes on a high end machine. I'd really like to speed it up. I have found this tip which recommends using a spatial index, but the example it gives is for IP addresses. However, the speed increase (436s to 3s) is impressive. How can I use this with timestamps?

  • Visual Studio: How to override the default "Build Action" for certain extension types per project or solution?

    - by Lukasz Podolak
    I'm serving my asp.net mvc views from many assemblies and copying views to the main application on post-build event. This works, however, I realized, that when I change something in view and just hit F5, changes are not included. What I have to do to see changes is to: save, build<- explicitly clicking, and then hit F5. However, it's pretty annoying solution. I discovered that setting Build action to "Embedded Resource" on view solves the problem as well, however other devs may not remember that they have to do this after adding every view to the solution. Is there a way to override the default build action for certain file extensions, such as: *.aspx, *.ascx in project or (better) in solution ? What I've found is an ability to add this setting globally, per machine, but I do not want to do that (link: http://blog.andreloker.de/post/2010/07/02/Visual-Studio-default-build-action-for-non-default-file-types.aspx) Any ideas ?

  • The Best BPM Journey: More Exciting Destinations with Process Accelerators

It was interesting to hear definite patterns emerging from those conversations: “BPM is a journey”, “experiences to share”, “our organization now understands what BPM is”, and my favorite (with some caveats): “BPM is like wine tasting, once you start, you want to try more”. These customers have started their journey, climbed up the learning curve, and reached a vantage point that allows them to see their next BPM destination. They see the next few processes they are going to tackle and improve with BPM. These processes/destinations target both horizontal processes where BPM replaces or coordinates manual activities, and critical industry processes that the company needs to improve to compete and deliver increasing value. Each new destination generates value, allowing the organization to reduce the cost of manual processes that were not supported by apps/custom development, and increase efficiency of end-to-end processes partially covered by apps/custom dev. The question we wanted to answer is how to help organizations experience deeper success with BPM, by increasing their awareness of the potential for reaching new targets, and equipping them with the right tools. We decided that we needed to identify destinations, and plot routes to show the fastest path to those destinations. In the end we want to enable customers to reach “Process Excellence”: continuously set new targets and consistently and efficiently reach them. The result is Oracle Process Accelerators (PA), solutions built using the rich functionality in Oracle BPM Suite. PAs offers a rapidly expanding list of exciting destinations. Our launch of the latest installment of Process Accelerators at Oracle Open World includes new Industry-focused solutions such as Public Sector Incident Reporting and Financial Services Loan Origination, and improved other horizontal PAs, including Travel Request Management, Document Routing and Approval, and Internal Service Requests. Just before OOW we had extended the Oracle deployment of Travel Request Management, riding the enthusiastic response from early adopters among travelers (employees), management and support (approvers). “Getting there first” means being among the first to extract value from the PA approach, while acquiring deeper insights into the customers’ perspective. This is especially noteworthy when it comes to PAs, a set of solutions designed to be quickly deployed and iteratively improved by customers. The OOW launch has generated immediate feedback from customers, non-customers, analysts, and partners. They all confirmed that both Business and IT at organizations benefit from PAs when it comes to exploring the potential for BPM to improve their business processes. PAs help customers visualize what can be done with BPM, and PAs are made to be extended: you can see your destination, change the path to fit your needs, and deploy. We're discovering new destinations/processes that the market wants us to support, generic enough across industries and within industries. We'll keep on building sets of requirements, deliver functional design, construct solutions using Oracle BPM, and test them not only functionally but for performance, scalability, clustering, making them robust, product-quality. Delivering BPM solutions with product-grade quality is the equivalent of following a tried-and-tested path on a map. Do you know of existing destinations in your industry? If yes, we can draw a path to innovative processes together.

  • XMLHttpRequest cross site scripting on same server but differnt port

    - by clamp
    hello, using XMLHttpRequest it is not possible to open a connection to a document on a different domain than where the page itself is hosted. but what about different ports? for example i have a webserver running on my machine listening on port 80 so the webaddress would look like this: http://localhost:80/mypage.html and i have another webserver running on localhost which is meant to process the ajax requests but listens on a different port. so the javascript in mypage.html would look like this: var xmlhttprequest = new XMLHttpRequest(); xmlhttp.open("GET", "http://localhost:1234/?parameters", true); xmlhttp.send(); would this work? or will it give a security exception as well?

  • Attach Console to Service

    - by MemphiZ
    I currently have a WCF Service Library which will be started through a Console Application acting as ServiceHost. The ServiceHost starts the service and then waits with Console.ReadLine() for the "quit" command. If i do "Console.WriteLine();" in the service this will be printed to the ServiceHosts Console of course. The Service prints some information when the clients connect for example. Is it possible to have the ServiceHost converted to a real Windows Service (to start up when the machine boots without console window) and attach or detach a command prompt (cmd.exe) or another Console Application to it when needed? For example if I want so see which clients connect from now on? Thanks in advance!

  • Is a .Net membership database portable, or are accounts somehow bound to the originating Web site or

    - by Deane
    I have an ASP.Net Web site using .Net Membership with a SQL Server provider, so the users and roles are stored in the SQL tables created by Aspnet_regsql.exe. Is this architecture totally self-contained and portable, or are users in it somehow bound to the specific Web site on which they create their account? Put another way, if we create a bunch of users in dev or UAT, the back up and restore this database to another server, accessed under another domain name, should it still work just fine? We're seeing some odd behavior when we move the database, like users losing group affiliation and such, and I'm curious how portable and environment-agnostic this database really is. I have a sneaking suspicion that something is bound to the machine key or the domain.

  • What to monitor on MSSQL Server

    - by user361434
    Hi all I have been asked to monitor MSSQL Server (2005 & 2008) and am wondering what are good metrics to look at? I can access WMI counters but am slightly lost as to how much depth is going to be useful. Currently I have on my list: user connections logins per second latch waits per second total latch wait time dead locks per second errors per second Log and data file sizes I am looking to be able to monitor values that will indicate a degradation of performance on the machine or a potential serious issue. To this end I am also wondering at what values some of these things would be considered normal vs problematic? As I reckon it would probably be a really good question to have answered for the general community I thought i'd court some of you DBA experts out there (I am certainly not one of them!) Apologies if a rather open ended question. Ry

  • Error including image in Latex

    - by euphoria83
    I am getting the following error while compiling my Latex File : ! LaTeX Error: Cannot determine size of graphic in tree.jpg (no BoundingBox). Why do I get this error ? What has this to do with an .eps file ? Infact, I could compile it fine with MacTex on my machine. But when I submit it online to a scientific journal for publication, it compiles it on the server and sends me the resultant PDF which as all these error that prevent it from compiling. I am using the following syntax for including the images : \begin{figure}[!h] \begin{center} \scalebox{0.45}{ \includegraphics{tree.jpg}} \end{center} \caption{\small A sample} \label{tree} \end{figure} What should I do ? Could it be that their server is using an old compiler ? UPDATE : It finally worked. I converted the first image to PDF and the compilation happened perfectly. I guess it used the bounding box value from that PDF and applied it to all images.

I'd like the numbers to scroll by as if they're on a slot machine wheel. I've managed to mostly hack something together using the ScrollTo plugin, but it's slow and choppy. It always stops briefly at certain divs along the way. Perhaps I'm using it wrong. Is there a better way to accomplish such an effect?

  • Jetty 6: Unknown Error 99

    - by Silvio Donnini
    The system I'm developing is comprised of a jetty server (v6.1.2rc4) and a php frontend that sends http requests to jetty via curl_exec. The server and the client are on the same machine. The requests I send can be both POSTs and GETs, I get the same error for either which is: Failed to connect to 127.0.0.1: Unknown error 99 This is rather cryptic. It seems that after the first problematic request, some of the following (unrelated) requests also get corrupted. It looks like jetty is simply refusing the connection, but I can't read more than that into the error message. I thought it was a problem with the server's configuration, so I tried changing jetty's maxIdleTimeMs, but without success. Any idea about what to do is welcome thanks, Silvio

  • Why is floating point byte swapping different from integer byte swapping?

    - by CJ
    I have a binary file of doubles that I need to load using C++. However, my problem is that it was written in big-endian format but the fstream operator will then read the number wrong because my machine is little-endian. It seems like a simple problem to resolve for integers, but for doubles and floats the solutions I have found won't work. How can I (or should I) fix this? I read this as a reference for integer byte swapping: http://stackoverflow.com/questions/105252/how-do-i-convert-between-big-endian-and-little-endian-values-in-c

  • Java memory mapped files and swap

    - by MarkS
    I'm looking at some memory mapped files in Java. Let's say I have a heap size set to 2gb, and I memory map a file that is 50gb - far more than the physical memory on the machine. The OS will cache parts of that 50gb file in the os file cache, the java process will have 2gb of heap space. What I'm curious about is how does the OS decide how much of the 50gb file to cache? For instance, if I have another java process, also with a 2gb heap size, will that 2gb be swapped out to allow the os to cache parts of the memory mapped file? Will parts of the heap space of the first process be swapped out to allow the OS to cache? Is there any way to tell the OS not to swap heap space for OS caching? If the OS doesn't swap out main processes, how does it determine how big its file cache should be?

  • WMI: How to differentiate between Wireless mouse and touch screen

    - by kingas
    I am using Win32_PointingDevice class to detect mice connected to the system. I ran my device discovery script on a machine which has touch screen. The discovery shows up with 3 pointing devices, directly connected USB mouse, wireless mouse and touch screen. My question is how to distinguish between USB mouse with touch screen. If Win32_PointingDevice class doesn't provide information then are there any other methods which I can use to get mouse and touch information. This is extension to my previous question at http://stackoverflow.com/questions/1746689/wmi-class-for-wireless-mouse
