• memory and time intensive php task

  - by Goddard

  Sorry if this question has been asked before, but I couldn't find anything usable. I'm working on a project for a client and currently I have to loop through the users table which is about 3000 records and still growing. I have to do some calculations on a nightly basis which I am going to be using cron/php. The calculations script uses about 3.5mb of memory and takes about 1 second to run. When loading individual users my current php setup handles this fine, but if I try and loop through the user list my php script execution time runs out. I've read after doing some searching that I can make the page reload itself after each user calculation and just keep my previous place in the loop and this sounds like a good idea, but I wanted to hear some opinions from others that have handled similar situations and how you handled these types of tasks. Thanks.

• client website compromised, found a strange .php file. any ideas?

  - by Kevin Strong

  I do support work for a web development company and I found a suspicious file today on the website of one of our clients called "hope.php" which contained several eval(gzuncompress(base64_decode('....'))) commands (which on a site like this, usually indicates that they've been hacked). Searching for the compromised site on google, we got a bunch of results which link to hope.php with various query strings that seem to generate different groups of seo terms like so: (the second result from the top is legitimate, all the rest are not) Here is the source of "hope.php": http://pastebin.com/7Ss4NjfA And here is the decoded version I got by replacing the eval()s with echo(): http://pastebin.com/m31Ys7q5 Any ideas where this came from or what it is doing? I've of course already removed the file from the server, but I've never seen code like this so I'm rather curious as to its origin. Where could I go to find more info about something like this?

• Which folders need to be backedup for migration in Joomla?

  - by Devdatta Tengshe

  I have never used Joomla before, so this might be a noobish question. I have tried searching, but haven't found anything relevant. I'm helping someone update & migrate their old website, built on the Joomla framework. Currently it is running on Joomla 1.5.8 which is an ancient version. I've convinced them to upgrade Joomla to atleast 2.5 I have already taken the database backup. Most links I have seen talk of backing up the entire public_html folder (The website runs on a shared host). But in my fresh Joomla installation there are several folders that are in the public_html folder. So which of the folders in the public_html folder are from the content of the website, and which are of the old Joomla framework? I'm afraid that I might overwrite files of the new Joomla framework with the old framework, if copy all the files and folders into the new installation.

• Learn a language bottom-up or top-down?

  - by Hanno Fietz

  When starting the first project in a new language, you have basically two approaches to learning. Either you do a quick Google search, pull together the most popular frameworks and libraries and work your way from their tutorials towards what you want to achieve (top-down). Or you start with the language basics and the standard library and by and by replace your own simple components with more sophisticated third-party components once you know what you're searching for (bottom-up). Now I'm about to embark on my first serious Javascript project. There's probably as much to know about the language as there is about jQuery, ExtJS and whathaveyou, and I'm trying to decide what to focus on.

• How to show the right country domain in Google Places?

  - by Baumr

  Background A site has multiple ccTLDs: example.com for the US, example.co.uk for UK users, example.de for Germans, etc. Googling for certain city keywords will return rich snippets with a list of Google Places: Problem When searching on Google Germany, the domain for US users (example.com) appears instead of the corresponding ccTLD (example.de). This is not good user experience, as users would most likely like to book on a site localized for them (e.g. language and currency). Question What solutions are there? Is it possible to return different ccTLDs in rich snippets for Google searches in Germany/UK? Ideas Would implementing the hreflang annotation resolve this? What about entering multiple corresponding URLs in the structured data markup?

• DirectX 9.0c and C++ GUI

  - by SullY

  Well, I'm trying to code a gui for my engine, but I've got some problems. I know how to make a UI overlay but buttons are still black magic for me. Anything I tried was to compilcated ( if it goes big ). To Example I tried to look if the mouse position is the same as the Pixel that is showing the button. But If I use some bigger areas it's getting to complicated. Now I'm searching for a Tutorial how to implement your own gui. I'm really confused about it. Well I hope you have/ know some good tutorials. By the way, I took a look at the DXUTSample, but it's to big to get overview.

• Gmail Now Searches Inside PDF, Word, and PowerPoint Attachments

  - by Jason Fitzpatrick

  Gmail has long had a robust system for searching within the subjects and bodies of your emails, now you can search inside select attachments–PDF, Word, and PowerPoint attachments are all searchable. Prior to this update, Gmail could search inside of HTML attachments but lacked more advanced attachment querying abilities. Now when you search your Gmail account you’ll see search results for not only the subject and body contents but also the contents of popular formats like PDF and Word documents. Don’t forget to take advantage of advanced search terms to speed up your query. If you know the information you need is in an attachment but can’t remember which email, include “has:attachment” in your search to only peek inside emails with attachments.

• Best practice for SEO "special characters" in products pages

  - by rhodesit

  Whats a best practice for creating websites do to the fact that i need to enter "ö" within the content/title/meta. Should I spell it without, and just use a "normal" character or do i put in this code everywhere. or do i spell it half the time with and half the time without. whats the best practice for seo? Google takes into account user intent. Which makes things complicated(in my mind). The user will be searching without the "special characters" but because of the whole "user intent" thing, I don't know the best practice for this situation is. Should I use a mix of both spellings? Should I use the special characters in anchortext/headers/title/metadescription?

• Can I host a high traffic website at home?

  - by eric01

  I've been searching this up on google but I can't formulate my google search with the right terms to find an accurate answer to my question. Is it possible to have a super-fast connection at home to host a high traffic website? What is the generic term for that kind of connection? What's the major drawback of hosting at home? (I have no idea of the price range but it's probably quite expensive) Do you have to be a company to have the right to own such a connection?

• Ways to find a tutor for 1st year University student

  - by Craig H

  I tried searching here (and SO) without much luck. I also stared at the yellow box to the right and think this question is relatively on topic and can be answered. A co-worker asked me if I had any suggestions for how to find a tutor for his son. In this specific case, it was for Eclipse and Java, but it got me thinking about good general strategies one could use in situations like this. He preferred a local 1-to-1, but I suppose online might be a reasonable (or perhaps more likely) alternative. Any suggested strategies?

• How do I make Unity quit opening Firefox under the Shiretoko icon?

  - by Azendale

  I'm using Ubuntu 12.04, and whenever I open Firefox, whether it is from searching on the dash or clicking a 'quick-launch' launcher, it always opens yet another icon for the running instance that is a blank page and says Shiretoko. It will pulse the Firefox icon for a while (I'm guessing until a timeout or something). It's as if Unity no longer recognizes the Firefox process as Firefox and misidentifies it as Shiretoko. (I know Shiretoko was a testing version of Firefox a long time ago.) How do I set Unity straight? I imagine that it has something to do with me once using Shiretoko, but I believe that was even on a different installation, just the same home folder. Is there some place Unity caches this information that I can clear (or remove specific parts of)?

• SmS Gateways - How do other sites do it? [closed]

  - by chobo2

  Possible Duplicate: Send and Receive SMS from my Website I would love to have a feature on my site that sends Email reminders and SmS(text messages) to people mobile phones. I been searching around and all I am finding is api's that charge money per SmS message(as low as 1cent per message). However even at 1cent per message that is still too much. The amount of money I am charging per year could be servilely eroded by just the Sms messages along. I could of course charge more money for my service or have an add on for SmS messages but I don't think either would work as most people expect it to be free feature and if they have to pay anything that is because of their carrier charging them not the website. How do other sites do it? I guessing companies like google have their own gateway providers or something like that. But how about smaller sites what do they do? I can't see them paying per sms text message.

• What would be a good game making engine supporting Vector images?

  - by Qqwy

  I want to create a simple platforming game, in which you are a square in a wonderful world. I would like this game to be able to be played in browsers. Basically I am searching for something similar to "Flixel", but with the following features: Support Vector Graphics Allow zooming/rotating objects without producing huge amounts of lag as soon as you are using more objects. (Because I want to rotate the map around the player) So in other words, preferably zoom the viewport/camera instead of the objects themselves. Does an engine like that exist?

• Low CPU/Memory/Memory-bandwith Pathfinding (maybe like in Warcraft 1)

  - by Valmond

  Dijkstra and A* are all nice and popular but what kind of algorithm was used in Warcraft 1 for pathfinding? I remember that the enemy could get trapped in bowl-like caverns which means there were (most probably) no full-path calculations from "start to end". If I recall correctly, the algorithm could be something like this: A) Move towards enemy until success or hitting a wall B) If blocked by a wall, follow the wall until you can move towards the enemy without being blocked and then do A) But I'd like to know, if someone knows :-) [edit] As explained to Byte56, I'm searching for a low cpu/mem/mem-bandwidth algo and wanted to know if Warcraft had some special secrets to deliver (never seen that kind of pathfinding elsewhere), I hope that that is more concordant with the stackexchange rules.

  - by Tim

  I don't know how it suddenly became this but here's what's happening right now: e.g. I have 2 firefox windows open, so I see 2 small arrows on the left side icon of the unity launcher. Before, when I click on the firefox icon, I see 2 small windows of the firefox so I can choose which one. Now it suddenly stopped working. (super+W still works though).

• On-board HDMI Audio

  - by TrackStar

  I have tried searching for answers to this issue but have had no luck. My HDMI display is working but I have no audio from the HDMI .There is no option for HDMI under sound preferences hardware or output. Purging and re-installing pulse audio doesn't change anything. I am using the on-board HDMI port on my motherboard, I do not have a PCI graphics card installed. CPU: i7-3770 Mobo: Asus Sabertooth z77 Kernel: 2.6.39-3-bb03 running aplay -l returns ** List of PLAYBACK Hardware Devices ** card 0: Intel [HDA Intel], device 0: ALC892 Analog [ALC892 Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: Intel [HDA Intel], device 1: ALC892 Digital [ALC892 Digital] Subdevices: 1/1 Subdevice #0: subdevice #0 Seems as if the system doesn't even recognize the possibilty of HDMI audio output. Any ideas?

• Selective bandwidth shaping

  - by the_candyman

  I was searching something for bandwidth shaping. I found trickled and wondershaper which works on the total bandwidth. I would like to know if there exists a selective bandwidth shaping. I mean, I run 2 application which uses internet. I would like to limit the bandwidth of one of these 2 in real time (just like a sound equalizer). For example, I'm downloading something. Meanwhile, someone calls me on skype. So I want to slow the downloading to have more band in my video calling. Is this possible?

• Android opengles 2.0 :different resolutions rendering and input

  - by kkan

  I'm currently developing a sprite based 2D game for android using opengles 2.0. I've got some basic rendering done that mimics the spritebatch functionality of xna (draw sprite, rotation, color). But all of this works for a fixed projection matrix, but android has a lot of screen sizes. Q1)Would this be an okay method to scale up/down the drawing? 1)Draw the whole screen to a texture. 2)Draw the above texture as a quad to the device. I found the above through some searching, not sure if it's the best one, are there any alternatives? Q2)How do you handle inputs for different resolutions? I currently get the position of a touch and use it raw. Would it be okay to get the position, and then scale the position to size of the texture used for rendering, and the perform calculations on it? Thanks.

• tty1 prompt before lightdm

  - by David Weldon

  After upgrading to 13.10, every time I boot I'm shown a login prompt (tty1) for ~30 seconds before lightdm automatically starts. Everything works fine after that. Any ideas on what I could try to fix/debug this? My /var/log/lightdm/x-0-greeter.log contains lines like the following: ** (at-spi2-registryd:1381): WARNING **: Failed to register client: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.gnome.SessionManager was not provided by any .service files ** (at-spi2-registryd:1381): WARNING **: Unable to register client with session manager WARNING: Failed to open sessions directory: Error opening directory '/usr/share/lightdm/sessions': No such file or directory ** Message: PID 1534 (we are 1534) sent signal 15, shutting down... ** (gnome-settings-daemon:1401): WARNING **: Name taken or bus went away - shutting down Searching for these errors results in a variety of bugs filed over the years. Maybe a clean install will fix this.

• Facebook Java API

  - by Filippo

  I'd like to write a program in java (not a servlet, not jsp, not a webapp) which allows me to do simple things, such as connecting to a FB account and retrieve the status or posts on the wall. I know facebook no longer supports official JavaAPI, so I was wondering what are the best (and most simple, being the program very basic) unofficial api out there. If possible, i would also like some example-code. searching through the web, I've read that you need two secret keys to create a facebook application, and I have not a fb account. Is it indispensable to have an account? thank you everyone

  I want to open the Application lens in the Unity Dash as the default lens, since I much more open a programm then searching for a wikipedia article, the weather or anything else the home lens offers. Here How do I show the Applications Lens By Default? and here What are Unity's keyboard and mouse shortcuts? are the same questions, but the suggested answers don't work anymore on Trusty. I know that I can open the application lens with Super + A but I just would like to press Super to open it. An alternative would be to only get online suggestions whe partikular asked for them, but even though I just select the application scope in the filter section I get some useles online results. Btw. I don't want to open the online search results in generall, since I just reactivated them to try it out.
