  • Using SimpleModal (jQuery plugin) to display a popup iFrame without unnecessary scrollbars

    - by Alex Black
    I'm using SimpleModal: http://www.ericmmartin.com/projects/simplemodal/ And displaying an iframe, as per the example: // Display an external page using an iframe var src = "http://365.ericmmartin.com/"; $.modal('<iframe src="' + src + '" height="450" width="830" style="border:0">', { closeHTML:"", containerCss:{ backgroundColor:"#fff", borderColor:"#fff", height:450, padding:0, width:830 }, overlayClose:true }); And the popup has two sets of scrollbars, one perhaps for the HTML element representing the popup, and one for the iFrame. Try the demo to see. Ideally I'd like no scrollbars if the content fits, otherwise a single vertical scrollbar. Any ideas? Thanks! Alex

  • JQuery live event binding prevents additional callbacks

    - by Alex Ciminian
    Hey! I was building an AJAX listing of elements in my site, with the ability to delete them (also via AJAX). The following piece of code handles the deletion: $('ul.action-menu a.delete').live('click', function () { $.post($(this).attr('href'), function (data) { var recvData = eval( '(' + data + ')' ); if ((recvData.status == 1) && (recvData.delId)) { $('#alert-' + recvData.delId).fadeOut(); } else { alert(recvData.message); } }); return false; }); This works just fine. The problem is that, for elements that were not there when the page was loaded (i.e. that were added dynamically), the post callback does not get executed and it doesn't fade out after being deleted (the AJAX call is being made, it just doesn't execute the callback). Do you have any idea why this is happening? Thanks, Alex

  • Nginx A/B testing

    - by Alex
    Hey, I'm trying to do A/B testing and I'm using Nginx fo this purpose. My Nginx config file looks like this: events { worker_connections 1024; } error_log /usr/local/experiments/apps/reddit_test/error.log notice; http { rewrite_log on; server { listen 8081; access_log /usr/local/experiments/apps/reddit_test/access.log combined; location / { if ($remote_addr ~ "[02468]$") { rewrite ^(.+)$ /experiment$1 last; } rewrite ^(.+)$ /main$1 last; } location /main { internal; proxy_pass http://www.reddit.com/r/lisp; } location /experiment { internal; proxy_pass http://www.reddit.com/r/haskell; } } } This is kind of working, but css and js files woon't load. Can anyone tell me what's wrong with this config file or what would be the right way to do it? Thanks, Alex

  • How to sign installation files of a Visual Studio .msi

    - by Alex
    This may be a duplicate, though I can't find it at this time. If so please point me in the right direction. I recently purchased an authenticode certificate from globalsign and am having problems signing my files for deployment. There are a couple of .exe files that are generated by a project and then put into a .msi. When I sign the .exe files with the signtool the certificate is valid and they run fine. The problem is that when I build the .msi (using the visual studio setup project) the .exe files loose their signatures. So I can sign the .msi after it is built, but the installed .exe files continue the whole "unknown publisher" business. How can I retain the signature on these files for installation on the client machine? You help is appreciated. -Alex

  • Template engine recommendations

    - by alex
    I'm looking for a template engine. Requirements: Runs on a JVM. Java is good; Jython, JRuby and the like, too... Can be used outside of servlets (unlike JSP) Is flexible wrt. to where the templates are stored (JSP and a lot of people require the templates to be stored in the FS). It should provide a template loading interface which one can implement or something like that Easy inclusion of parameterized templates- I really like JSP's tag fragments Good docs, nice code, etc., the usual suspects I've looked at JSP- it's nearly perfect except for the servlet and filesystem coupling, Stringtemplate- I love the template syntax, but it fails on the filesystem coupling, the documentation is lacking and template groups and stuff are confusing, GXP, TAL, etc. Ideas, thoughts?

  • Detecting (on the server side) when a Flex client disconnects from BlazeDS destination

    - by Alex Curtis
    Hi all, I'd like to know whether it's possible to easily detect (on the server side) when Flex clients disconnect from a BlazeDS destination please? My scenario is simply that I'd like to try and use this to figure out how long each of my clients are connected for each session. I need to be able to differentiate between clients as well (ie so not just counting the number of currently connected clients which I see in ds-console). Whilst I could program in a "I'm now logging out" process in my clients, I don't know whether this will fire if the client simply navigates away to another web page rather than going though said logout process. Can anyone suggest if there's an easy way to do this type of monitoring on the server side please. Many thanks, Alex

  • Running Awk command on a cluster

    - by alex
    How do you execute a Unix shell command (awk script, a pipe etc) on a cluster in parallel (step 1) and collect the results back to a central node (step 2) Hadoop seems to be a huge overkill with its 600k LOC and its performance is terrible (takes minutes just to initialize the job) i don't need shared memory, or - something like MPI/openMP as i dont need to synchronize or share anything, don't need a distributed VM or anything as complex Google's SawZall seems to work only with Google proprietary MapReduce API some distributed shell packages i found failed to compile, but there must be a simple way to run a data-centric batch job on a cluster, something as close as possible to native OS, may be using unix RPC calls i liked rsync simplicity but it seem to update remote notes sequentially, and you cant use it for executing scripts as afar as i know switching to Plan 9 or some other network oriented OS looks like another overkill i'm looking for a simple, distributed way to run awk scripts or similar - as close as possible to data with a minimal initialization overhead, in a nothing-shared, nothing-synchronized fashion Thanks Alex

  • github url style

    - by Alex Le
    Hi all, I wanted to have users within my website to have their own URL like http://mysite.com/username (similar to GitHub, e.g. my account is http:// github. com/sr3d). This would help with SEO since every profile is under the same domain, as apposed to the sub-domain approach. My site is running on Rails and Nginx/Passenger. Currently I have a solution using a bunch of rewrite in the nginx.conf file, and hard-coded controller names (with namespace support as well). I can share include the nginx.conf here if you guys want to take a look. I wanted to know if there's a better way of making the URL pretty like that. (If you suggest a better place to post this question then please let me know) Cheers, Alex

  • How to determine Windows.Diagnostics.Process from ServiceController

    - by Alex
    This is my first post, so let me start by saying HELLO! I am writing a windows service to monitor the running state of a number of other windows services on the same server. I'd like to extend the application to also print some of the memory statistics of the services, but I'm having trouble working out how to map from a particular ServiceController object to its associated Diagnostics.Process object, which I think I need to determine the memory state. I found out how to map from a ServiceController to the original image name, but a number of the services I am monitoring are started from the same image, so this won't be enough to determine the Process. Does anyone know how to get a Process object from a given ServiceController? Perhaps by determining the PID of a service? Or else does anyone have another workaround for this problem? Many thanks, Alex

  • Modifying generator.yml views in Symfony

    - by Alex Ciminian
    Hey! I'm currently working on a web app written in Symfony. I'm supposed to add an "export to CSV" feature in the backend/administration part of the app for some modules. In the list view, there should be an "Export" button which should provide the user with a csv file of the elements that are displayed (considering filtering criteria). I've created a method in the actions class of the module that takes a comma separated list of ids and generates the CSV, but I'm not really sure how to add the link to it in the view. The problem is that the view doesn't exist anywhere, it's generated on the fly from the data in the generator.yml configuration file. I've posted the relevant part of the file below. list: display: [=name, indemn, _status, _participants, _approved_, created_at] title: Lista actiuni object_actions: _edit: ~ _delete: ~ filters: [name, county_id, _status_filter, activity_id] fields: name: name: Nume Actiune indemn: name: Îndemn la actiune description: name: Descriere approved_: name: Operatiune created_at: name: Creata la status: name: Status Actiune I'm new to Symfony, so any help would be appreciated :). Thanks, Alex

  • Vim OmniCppComplete on vectors of pointers

    - by Alex
    Hi, I might have done something wrong in the set up but is OmniCppComplete supposed to provide the members/functions of classes when doing this? vectorofpointers[0]-> At the moment all I get when trying that are things relating to the vector class itself, which obviously isn't very useful. I think it might have been working before I tagged /usr/include/ but I could be wrong. Also, is it possible to disable the preview window? I find it just clutters up my workspace. And since I enabled ShowPrototypeInAbbr I don't really need it. Thanks, Alex

  • C# setup project output automatically start with administrative rights

    - by Alex
    Hi, i've created an setup project for a .net-application which works fine. The problem is, that the application begins to write log-files after startup and this requires administrative rights on windows vista and windows 7. I know there are some folders which i could use to write into without administrative rights. When i start the application as administrator, everything works fine. I asked myself, if it's possible to change the setup project in visual studio in a way that the installed application automatically owns administrative rights on the target system? Thanks for every help in advance! Alex

  • Looking for some thoughts on an image printing app

    - by Alex
    Hey All, Im looking for thoughts/advice. I have an upcoming project (all .net) that will require the following: pulls data once a day from an online service provider based on certain criteria. saves data locally for reference and reporting the data thats pulled will be used to create gift cards. So after the data is loaded, a process will run to generate "virtual cards" and send them to a network printer. Once printed, the system will updated the local data recording a successful or failed print. My initial thought was to create a windows service to pull the data...but then I couldnt decide how I was going to put a "virtual card" together and get it to print. Then I considered doing it as a WPF app. I figure that will give me access to the graphics and printing ability. Maybe neither of these are the right direction....Any ideas or thoughts would be greatly appreciated. Alex

  • Setting refresh-policies in Ehcache

    - by Alex Ciminian
    Is there any to specify a data refresh policy in Ehcache? I am currently migrating an application from OSCache to Ehcache and I can't seem to find any way to specify when an element needs refreshing, besides setting timeToIdle and timeToLive. What I want is: on accessing an element from the cache, check with it's associated resource to see if it was updated later than the lastUpdateTime of the cache element. If yes, refresh the cache; else serve the content from the cache. In OSCache this was done by catching NeedsRefreshExceptions and setting custom refresh policies for the elements. I've been digging around in the docs for a while now, but I wasn't able to find any methods or examples of how I could accomplish this in Ehcache. Any help would be appreciated :). Alex

  • Calculating co-ordinate of a point on a path given a distance

    - by Alex
    I'm working on a project that surveys the condition of a road or highway using a calibrated trip computer connected to a rugged-PC. An operator keys in defect codes as they travel along a pre-defined route. I need to show an indicator on the map screen that shows the vehicles current position, taking into account the distance data from the trip computer. I know the exact lat lon co-ordinates at the starting point of each section of road, and the road is made up of a series of points. The question is: how can I calculate the lat lon co-ordinates of the vehicle assuming that it has continued on the route and traveled a certain distance (e.g. 1.4km). The co-ordinates would be 'locked onto' the road line, as shown in blue on the diagram below. Thanks, Alex

  • Get status of servlet request before the response is returned

    - by Alex
    Good evening, I am in the process of writing a Java Servlet (Struts 2, Tomcat, JSP etc) which is capable of doing some fairly complex simulations. These can take up to 2 minutes to complete on the and will return a graph of the results. It is trivial to calculate the percentage of the simulation completed because the process works by repeating the same calculations 1000s of times. I would be interested to know if anyone has ever tried to use client side technology to provide any estimate of the percentage complete. I.e query the servlet processing to get the number of cycles completed at various point throughout the simulation. This could then be displayed as a bar in the client browser. Any thoughts, advice, resources would be much appreciated. Thanks, Alex

  • WCF high instance count: anyone knows negative sideffects?

    - by Alex
    Hi there! Did anyone experience or know of negative side effects from having a high service instance count like 60k? Aside from the memory consumption of course. I am planning to increase the threshold for the maximum allowed instance count in our production environments. I am basically sick of severe production incidents just because "something" forgot to close a proxy properly. I plan to go to something like 60k instances which will allow the service to survive using default session timeouts at a call rate average for our clients. Thanks, Alex

  • What is the difference between MVC model 1 and model 2?

    - by Alex Ciminian
    I've recently discovered that MVC is supposed to have two different flavors, model one and model two. I'm supposed to give a presentation on MVC1 and I was instructed that "it's not the web based version, that is refered to as MVC2". As the presentations are about design patterns in general, I doubt that this separation is related to Java (I found some info on Sun's site, but it seemed far off) or ASP. I have a pretty good understanding of what MVC is and I've used several (web) frameworks that enforce it, but this terminology is new to me. How is the web-based version different from other MVC (I'm guessing GUI) implementations? Does it have something to do with the stateless nature of HTTP? Thanks, Alex

  • "Circuit breaker" for net.msmq?

    - by Alex
    Hi, The Circuit Breaker pattern, from the book Release It!, protects a service from requests while it is failing (or recovering). The net.msmq binding used with transactions give us nice retry and poison message capabilities. But I am missing the implementation of such a "Circuit breaker" pattern. A service is put under even heavier load by retries while it is already in a failure condition (like DB connectivity issues causing loads of blocked threads etc.). Anyone knows about a behavior extension or similar that explicitly closes the service host when defined failure thresholds have been exceeded? Cheers, Alex

  • Sector bancario, un reto de transformación tecnológica

    - by Fabian Gradolph
    El sector financiero se encuentra en un momento clave. No sólo por la coyuntura económica actual, sino también por cuestiones estructurales y normativas que obligan a las entidades bancarias -normalmente a la cabeza de la innovación tecnológica, por cierto- a seguir dando pasos hacia el futuro, manteniendo la tecnología en el corazón de su estrategia de negocio. Así se ha puesto de manifiesto en el encuentro que se ha celebrado hoy en Madrid: Oracle in Banking, donde expertos de Oracle, clientes de la compañía y analistas han puesto sobre la mesa algunos de los desafíos a los que se enfrenta el sector e ideas para aprovechar al máximo la tecnología en la resolución de estos desafíos. El evento ha sido todo un éxito, con asistencia masiva de clientes y partners. En la imagen que ilustra este artículo pueden verse, por este orden: una panorámica de la sala, Modesto Villajos, Regional Sales Manager de Oracle, quien ejerció de maestro de ceremonias. Leopoldo Boado, Country Manager de Oracle España, quien realizó la introducción, Alex Kwiatkowski, de IDC, quien expuso los prinicipales desafíos a los que se enfrenta la banca, y Máximo Díez, Senior Director Financial Services de Oracle, que planteó las diferentes estrategias de transformación que pueden emprender los bancos. El evento se completó con intervenciones de clientes de Oracle (Banco Espírito Santo -BES- de Portugal; y BBVA, de España), y presentaciones y demostraciones técnicas.  De particular interés fue la intervención de Alex Kwiatkowski. De acuerdo con su punto de vista hay cuatro áreas esenciales a las que se enfrenta el sector. La primera de ellas es el marco regulatorio. El sector financiero está sometido a una constante presión normativa (probablemente acrecentada en estos tiempos de incertidumbre), no sólo a nivel nacional, sino también a nivel europeo y global. El cumplimiento exquisito de todas estas normas es esencial para el buen funcionamiento del sistema. La segunda área crítica es la necesidad de ofrecer una experiencia de usuario multicanal satisfactoria, de forma que se potencie la retención de clientes. A veces es difícil darnos cuenta, pero hoy en día nuestras interacciones con el banco han alcanzado una gran diversidad de canales (sucursal, ATM, Internet, banca telefónica, banca móvil...). Esto supone un permanente desafío tecnológico y de procesos para las entidades financieras. El tercer elemento crítico es el del incremento de la eficiencia de las operaciones, manteniendo los costes bajo control o incluso reduciéndolos aún más. Por último, las entidades bancarias tienen ante sí el reto de encontrar nuevas fuentes de ingresos, de forma que el foco deje de estar únicamente en la reducción de costes y la minimización de riesgos. Lo cierto es que en la actualidad, la atención principal se centra en estos dos puntos, pero como mencionó Alex Kwiatkowski "los CIO`s de los bancos se van a plantar en la mesa del CEO con la necesidad de realizar renovaciones completas de los sistemas de core banking y la necesidad de invertir en el desarrollo de nuevos canales". Máximo Díez también enfatizó esta necesidad en su presentación. Los bancos tienen la obligación de econtrar nuevas fórmulas para impulsar el crecimiento, pero la implementación de estrategias en este sentido presenta fuertes desafíos a causa de las limitaciones de los sistemas IT existentes. No hay duda de que se presenta un futuro muy interesante en el ámbito tecnológico para el sector financiero. Lo que Oracle puede hacer y ofrece a las entidades financieras puede encontrarse en este enlace: Financial Services.
