  • Is it convenient to use a XML/JSON generated based system? [closed]

    - by Marcelo de Assis
    One of my clients insists that we missed a requisite for the project(a little social network, using PHP + MySql), is that all queries are made from XML / JSON static files (using AJAX) and not directly from the database. Edit: The main reason, stated by client, is a way to economize bandwith. Even the file loading, has to be using AJAX, to avoid server side processing. We will still use a database to store and insert data. These XML / JSON files will be (re) generated whenever any data is changed by CMS or users. As the project was developed without this "technique", we'll have a lot of work ahead, so I would like to avoid that. I'm asking if it's convenient to use a XML generated based system, because I think a database is already "optimized" and secure to deal with a lot of data traffic. Other issue I'm afraid of, is a chance of conflict when a user is trying to read a XML/JSON which is being just generated.

  • Commenting Code AS3 - Not being an API

    - by Marcelo Noronha
    How should I comment a method? What are the best practices on commenting code? Example: /* Checks if a color is allowed in a given point * of the bitmapdata of the current floor * @param value - color to be checked * @return boolean - if color is allowed returns true, else, return false */ private function isAllowed(value:uint):Boolean { //code... } Is that the best way to comment a method? I´ve heard there´s the use of the tag @see. What should be on this tag? I wonder if it could be something that has a relation to the method, is that right? Thanks.

    I'm trying to add shortcuts to folders in "My Computer". This .reg almost works, I can execute programs like EXPLORE.exe, but I want to open a folder in the same window.

  • Cloudfront - How to invalidate objects in a distribution that was transformed from secured to public?

    - by Gil
    The setting I have an Amazon Cloudfront distribution that was originally set as secured. Objects in this distribution required a URL signing. For example, a valid URL used to be of the following format: https://d1stsppuecoabc.cloudfront.net/images/TheImage.jpg?Expires=1413119282&Signature=NLLRTVVmzyTEzhm-ugpRymi~nM2v97vxoZV5K9sCd4d7~PhgWINoTUVBElkWehIWqLMIAq0S2HWU9ak5XIwNN9B57mwWlsuOleB~XBN1A-5kzwLr7pSM5UzGn4zn6GRiH-qb2zEoE2Fz9MnD9Zc5nMoh2XXwawMvWG7EYInK1m~X9LXfDvNaOO5iY7xY4HyIS-Q~xYHWUnt0TgcHJ8cE9xrSiwP1qX3B8lEUtMkvVbyLw__&Key-Pair-Id=APKAI7F5R77FFNFWGABC The distribution points to an S3 bucket that also used to be secured (it only allowed access through the cloudfront). What happened At some point, the URL singing expired and would return a 403. Since we no longer need to keep the same security level, I recently changed the setting of the cloudfront distribution and of the S3 bucket it is pointing to, both to be public. I then tried to invalidate objects in this distribution. Invalidation did not throw any errors, however the invalidation did not seem to succeed. Requests to the same cloudfront URL (with or without the query string) still return 403. The response header looks like: HTTP/1.1 403 Forbidden Server: CloudFront Date: Mon, 18 Aug 2014 15:16:08 GMT Content-Type: text/xml Content-Length: 110 Connection: keep-alive X-Cache: Error from cloudfront Via: 1.1 3abf650c7bf73e47515000bddf3f04a0.cloudfront.net (CloudFront) X-Amz-Cf-Id: j1CszSXz0DO-IxFvHWyqkDSdO462LwkfLY0muRDrULU7zT_W4HuZ2B== Things I tried I tried to set another cloudfront distribution that points to the same S3 as origin server. Requests to the same object in the new distribution were successful. The question Did anyone encounter the same situation where a cloudfront URL that returns 403 cannot be invalidated? Is there any reason why wouldn't the object get invalidated? Thanks for your help!

  • Can I set up a 2nd home wireless router, with router2 connecting to the internet through a desktop which is wirelessly connected to router1?

    - by gil b.
    Hi, I apologize for the crudeness of my MSPaint drawing, but please view my diagram of what I'd like to accomplish: Proposed home network architecture Currently, all devices are connected to 1 wireless router. I would like to make my own subnet, with a box in-between my subnet and the shared wireless router, so that I can learn about IDS, traffic analysis, etc. I was also given a cisco PIX firewall to play around with, and it'd be an added bonus if I could incorporate that into my network. The reason for this proposed architecture is so that I can monitor all MY traffic, without seeing anything going on with my roommates' traffic. my MAIN Question is, is it possible to have my desktop connect to the wireless router with internet via wireless card AND share that connection via the ethernet card, hooked to wireless router 2? cable modem - wireless router - desktop pc connected wirelessly - wireless router 2 getting internet from wired connection to desktop pc - laptops connected wirelessly The PIX can be left out for now, but I'm wondering if it could eventually be incorporated? THANKS!

  • Large keepalive_requests values are severely slowing-down Nginx

    - by Gil
    When running a bacon (43-byte transparent pixel) load test on Nginx, we have tried several keepalive_requests values (from 10 to 100,000) and the optimal value seems to be 10. Here are the server HTTP headers of this tiny reply: HTTP/1.1 200 OK Server: nginx/1.5.6 Date: Wed, 23 Oct 2013 12:39:45 GMT Content-Type: image/gif Content-Length: 43 Last-Modified: Mon, 28 Sep 1970 06:00:00 GMT Connection: keep-alive Nginx is twice slower with keepalive_requests 100000 than with keepalive_requests 10. Can you help understanding that result? Or tell what we do wrong? For reference, here is the nginx.conf file.

  • Python multithreading not working on VPS server

    - by Sabirul Mostofa
    I am running an python multithreaded application with multiple processes which scrapes data from some websites. While running on my localhost It works great, but on the vps server I am using( Centos 5.8, 2.6 GHZ with 4 cores) performs very slow. From the nethogs command I get the network usage too low. I get around 8KBps with 15 threads. On other hand, in my PC I get the usage around 100-120KBPS. I have read about the Python GIL and threading limitations. It seems GIL never releases the lock on the VPS though it should while doing I/0 Is there any configuration in the VPS that I need to change for the threading to work properly?

  • ListView item background via custom selector

    - by Gil
    Is it possible to apply a custom background to each Listview item via the list selector? The default selector specifies @android:color/transparent for the state_focused="false" case, but changing this to some custom drawable doesn't affect items that aren't selected. Romain Guy seems to suggest in this answer that this is possible. I'm currently achieving the same affect by using a custom background on each view and hiding it when the item is selected/focused/whatever so the selector is shown, but it'd be more elegant to have this all defined in one place. For reference, this is the selector I'm using to try and get this working: <selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:state_focused="false" android:drawable="@drawable/list_item_gradient" /> <!-- Even though these two point to the same resource, have two states so the drawable will invalidate itself when coming out of pressed state. --> <item android:state_focused="true" android:state_enabled="false" android:state_pressed="true" android:drawable="@drawable/list_selector_background_disabled" /> <item android:state_focused="true" android:state_enabled="false" android:drawable="@drawable/list_selector_background_disabled" /> <item android:state_focused="true" android:state_pressed="true" android:drawable="@drawable/list_selector_background_transition" /> <item android:state_focused="false" android:state_pressed="true" android:drawable="@drawable/list_selector_background_transition" /> <item android:state_focused="true" android:drawable="@drawable/list_selector_background_focus" /> </selector> And this is how I'm setting the selector: <ListView android:id="@android:id/list" android:layout_width="fill_parent" android:layout_height="fill_parent" android:listSelector="@drawable/list_selector_background" /> Thanks in advance for any help!

  • SIMPLE reverse geocoding using Nominatim

    i am developing an online mapping application using OpenLayers + OpenStreetMaps. i need help implementing a simple reverse geocoding function in javascript (or php) that receives Latitude and Longitude and returns an Address. i would like to work with Nominatim, if possible. i do NOT want to use Google, Bing or CloudMade or other proprietary solutions. this link returns a reasonable response and i used simple_html_dom.php to break down the result but it is sort of an ugly solution. <?php include('simple_html_dom.php'); $url = "http://nominatim.openstreetmap.org/reverse?format=xml&lat=-23.56320001&lon=-46.66140002&zoom=27&addressdetails=1"; $html = file_get_html($url); foreach ($html->find('road') as $element ) { echo $element; } ?> any suggestions of a more elegant solution?

  • Very slow remote page load performance in QtWebKit (Windows)

    - by Gil
    I get very slow load times on QtWebKit on Windows 7, through ADSL. I am using the Qt Demo Browser, on a Core2 Quad, 64 bit Windows 7, 4GB ram, 2gb processor. through a VPN. Simplest example: google search page takes ~18 seconds to load, compared to 2.5 on Chrome (cash cleared). On larger pages, with scripts etc. it is worse. I tried Qt 4.6 and also the Qt 4.7 beta, but don't see any difference. I see the same results with Arora browser. Are there any settings, or patches that can be applied to fix this? Thanks

  • C++ HTML template framework, templatizing library, HTML generator library

    - by Marcin Gil
    I am looking for template/generator libraries for C++ that are similar to eg. Ruby's Erb, Haml, PHP's Smarty, etc. It would be great if I it would sport some basic features like loops, if/else, int conversion to strings, etc. Parameter passing to template rendering engine is also important if I could pass all of them in a hash map instead of calling some function for each of parameters. Do you have any recommendations? I can see also the possibility of embedding languages like Lua, however I haven't found a templatizing library for that either. Thanks!

  • Qt on Mac: where to find "configure"

    - by Gil
    hi, I am very new to Mac. I downloaded QT SDK Mac Open source (http://get.qt.nokia.com/qtsdk/qt-sdk-mac-opensource-2010.02.dmg) and installed the Package. I can run qmake, build samples and run demos, but I cannot run configure (in order to build the Qt libraries statically). It says: -bash: No such file or directory. Documentation says I should run this in the "Qt root folder", but what is this folder in Mac? I looked for it in /usr/bin, /usr/local/Qt4.6, /Developer/Tools/Qt. Anyway, what is "configure" on Mac. is it an executable or a script? Thanks a lot

  • Is there a summary of differences in rendering/behavior between QtWebKit and Chrome/Safari WebKit?

    - by Gil
    I wrote a simple Qt application (Windows+Mac) that uses QtWebKit to render a web site inside a window. But I already saw differences in layout and behavior between our app and Chrome (that uses WebKit as well), e.g.: - different fonts are displayed for the same web page - an html anchor link with "javascript:someFunction()" is not working Is there somewhere a summary list of all such differences (not the entire QtWebKit bug list)? Also: is there a way to use a WebKit version more similar to Chrome in my application?

  • How to embed a web browser control in a cross-platform application?

    - by Gil
    hi, I need to write quickly this application: a simple window that wraps a web browser control, that runs html pages. The Browser UI (e.g. Navigation buttons) should be suppressed. As a .net developer, I would embed the WebBrowser OCX in a Windows Form. But this has to run on Mac as well!! I found the following cross-platform candidates. Which one would you choose (in terms of simplicity, stableness, community support, etc.): 1) wxWidgets (www.kirix.com/labs/wxwebconnect.html) 2) QT: www.youtube.com/watch?v=Ee8eRwjbcFk&feature=related 3) MONO: www.mono-project.com/WebBrowser Thanks!
