• How can I use WebGL to create a tile-based multi-layer scrolling platform game?

  - by Nicholas Hill

  I've found WebGL (based on OpenGL) to be a fiendish and unforgiving framework for those learning to write HTML5-based games. Despite the presence of many examples on how to get started, I'm really struggling to understand how I could simply load a bunch of images and render them to a canvas quickly using WebGL. My specific scenario involves trying to render a map using a bespoke but simple multi-layered tile engine, where each value in a three dimensional array points to the image to use for that location in the rendered image. Think "Sonic the Hedgehog" via tilesets, tiles, maps, layers, sprites etc. Can anyone enlighten me: 1) How can I load an image that I can use as a texture in WebGL? 2) How can I dynamically select an image at run time and draw it at any co-ordinate, that I also select at run time?

• Transition to new site

  - by James Hill

  I'm almost finished rewriting the website for a non-profit organization. The existing site receives ~5,000 a month. The new site is being written in ASP.Net and the existing site is PHP. The current hosting provider does not support .Net hosting, so I'll be switching providers. My question revolves around the transition from the old site to the new. I would really like to get the new site up at the new hosting provider and do thorough testing before changing the DNS records for the domain. Question: How can I put the new site up, test it, make any changes/additions necessary before updating the domain DNS to point to the new IP without Google indexing the content? Also, what SEO repercussions should I be aware of when making such a drastic change to the content that exists under the domain name?

• Ubuntu 13.10 not playing DVD videos

  - by John Hill

  I installed Ubuntu Gnome 13.10 on my computer yesterday, and everything seems to be working fine so far, except that it isn't reading video or audio CD's and DVD's. At first, I inserted a DVD video, and it played normally for maybe 30-45 seconds before coming up with a "internal read error" or something like that. I was using the Totem player when the problem occurred, so I tried installing the VLC media player. It wouldn't read the disc at all, so I uninstalled the player. Now, the Totem player won't even begin playing the DVD. The player sometimes doesn't even open up when I insert the DVD, and other times it will but says it can't read it. I've tried several different DVD's and CD's with similar results. The computer is recognizing the optical drive, because when I open "Files", it shows the drive and the disc, but can't play it. Previously, I ran Ubuntu 13.04 with the Gnome desktop installed from the software center, and I had no issues. Any help is appreciated!

• Can WebGL be used to create a tile-based multi-layer scrolling platform game?

• Given two sets of DNA, what does it take to computationally "grow" that person from a fertilised egg and see what they become? [closed]

  - by Nicholas Hill

  My question is essentially entirely in the title, but let me add some points to prevent some "why on earth would you want to do that" sort of answers: This is more of a mind experiment than an attempt to implement real software. For fun. Don't worry about computational speed or the number of available memory bytes. Computers get faster and better all of the time. Imagine we have two data files: Mother.dna and Father.dna. What else would be required? (Bonus point for someone who tells me approx how many GB each file will be, and if the size of the files are exactly the same number of bytes for everyone alive on Earth!) There would ideally need to be a way to see what the egg becomes as it becomes a human adult. If you fancy, feel free to outline the design. I am initially thinking that there'd need to be some sort of volumetric voxel-based 3D environment for simulation purposes.

• Thread count in Java game

  - by Taylor Hill

  I'm just curious as to what a reasonable number of threads is for a simple 2D mmo in Java. Is it reasonable to have two threads per connection, one for the input stream and one for the output stream? The reason I ask is because I use a blocking method on the input stream, and a workaround seems unnecessarily complex if I were to try to get around it without adding threads. This is mostly for my own edification; I don't expect to have 5 million people playing it ever, or even 5, but I'm wondering what a good scalable solution is, and if this is reasonable for a small server (<30 connections).

• how to set php SERVER_PORT var to 80, behind varnish?

  - by Daniel

  how to force php to read SERVER_PORT as 80, when apache listens on 8080 and varnish listens on 80 ?? if my apache vhost is set to 8080, SERVER_PORT will always be 8080, this is troubling me a little since in many parts of the application some links are calculated with SERVER_NAME and SERVER_PORT together, .. so what I need is that php "believes" that SERVER_PORT is 80, so all links will pass trough varnish regards Daniel

• I want to use Windows 8 from within Ubuntu

  - by sus hill

  I have a CD of windows 8. I bought a laptop which has a windows 7 OS but I removed it to use Ubuntu 12.04 but for some of the programs I need Windows 8 without separate partitions. I heard about vmware and how it can help to run the OS insideanother. As I have only allocated 50GB for Ubuntu 12.04 64bit, which I am using right now, I want to use windows 8 from within my Ubuntu 12.04. Could anyone help? Thank you very much.

• No Sound via HDMI

  - by Goony Hill

  I have ubuntu installed on a Acer aspire revo 3700 intel atom processor with nvidia ion graphics this is plugged into a celcus 32 inch TV via HDMI (1080p). The video driver shows as an nvidia which I can select. I have set the sound to play via HDMI and the output to HDMI but get no sound. I have tried a sony 1080i TV with the box but get eratic results with the graphics, but the sound picks up straight away that is there is no need to select it. The graphics on the celcus TV work but I get a dialog box showing loads of different resolutions and frequencies which I have to close manually, these appear to be attempts to set different resolutions for the TV. Am I missing some sort of screen/sound driver, if so does anyone know what might support the celcus 32 inch (1080p) tv?

• How to model has_many with polymorphism?

  - by Daniel Abrahamsson

  I've run into a situation that I am not quite sure how to model. Suppose I have a User class, and a user has many services. However, these services are quite different, for example a MailService and a BackupService, so single table inheritance won't do. Instead, I am thinking of using polymorphic associations together with an abstract base class: class User < ActiveRecord::Base has_many :services end class Service < ActiveRecord::Base validates_presence_of :user_id, :implementation_id, :implementation_type belongs_to :user belongs_to :implementation, :polymorphic = true delegate :common_service_method, :name, :to => :implementation end #Base class for service implementations class ServiceImplementation < ActiveRecord::Base validates_presence_of :user_id, :on => :create has_one :service, :as => :implementation has_one :user, :through => :service after_create :create_service_record #Tell Rails this class does not use a table. def self.abstract_class? true end #Default name implementation. def name self.class.name end protected #Sets up a service object def create_service_record service = Service.new(:user_id => user_id) service.implementation = self service.save! end end class MailService < ServiceImplementation #validations, etc... def common_service_method puts "MailService implementation of common service method" end end #Example usage MailService.create(..., :user_id => user.id) BackupService.create(...., :user_id => user.id) user.services.each do |s| puts "#{user.name} is using #{s.name}" end #Daniel is using MailService, Daniel is using BackupService So, is this the best solution? Or even a good one? How have you solved this kind of problem?

• Test your internet connection - Emtel Mobile Internet

  After yesterday's report on Emtel Fixed Broadband (I'm still wondering where the 'fixed' part is), I did the same tests on Emtel Mobile Internet. For this I'm using the Huawei E169G HSDPA USB stick, connected to the same machine. Actually, this is my fail-safe internet connection and the system automatically switches between them if a problem, let's say timeout, etc. has been detected on the main line. For better comparison I used exactly the same servers on Speedtest.net. The results Following are the results of Rose Hill (hosted by Emtel) and respectively Frankfurt, Germany (hosted by Vodafone DE): Speedtest.net result of 31.05.2013 between Flic en Flac and Rose Hill, Mauritius (Emtel - Mobile Internet) Speedtest.net result of 31.05.2013 between Flic en Flac and Frankfurt, Germany (Emtel - Mobile Internet) As you might easily see, there is a big difference in speed between national and international connections. More interestingly are the results related to the download and upload ratio. I'm not sure whether connections over Emtel Mobile Internet are asymmetric or symmetric like the Fixed Broadband. Might be interesting to find out. The first test result actually might give us a clue that the connection could be asymmetric with a ratio of 3:1 but again I'm not sure. I'll find out and post an update on this. It depends on network coverage Later today I was on tour with my tablet, a Samsung Galaxy Tab 10.1 (model GT-P7500) running on Android 4.0.4 (Ice Cream Sandwich), and did some more tests using the Speedtest.net app. The results are actually as expected and in areas with better network coverage you will get better results after all. At least, as long as you stay inside the national networks. For anything abroad, it doesn't really matter. But see for yourselves: Speedtest.net result of 31.05.2013 between Cascavelle and servers in Rose Hill, Mauritius (Emtel - Mobile Internet), Port Louis, Mauritius and Kuala Lumpur, Malaysia It's rather shocking and frustrating to see how the speed on international destinations goes down. And the full capability of the tablet's integrated modem (HSDPA: 21 Mbps; HSUPA: 5.76 Mbps) isn't used, too. I guess, this demands more tests in other areas of the island, like Ebene, Pailles or Port Louis. I'll keep you updated... The question remains: Alternatives? After the publication of the test results on Fixed Broadband I had some exchange with others on Facebook. Sadly, it seems that there are really no alternatives to what Emtel is offering at the moment. There are the various internet packages by Mauritius Telecom feat. Orange, like ADSL, MyT and Mobile Internet, and there is Bharat Telecom with their Bees offer which is currently limited to Ebene and parts of Quatre Bornes.

• Tiny Wings - Placing items

  - by Federico

  I'm currently developing a Flash game like 'Tiny Wings'. I have a lot of work done, but i'm currently working on placing the items ( coins and obstacles ) on the terrain. My player it is moving on a auto-generated terrain (based on Emanuele Feronato's tutorials) so every time the player's x position is greater than (screenWidth + x) another hill is generated and so on. I'm currently having problems placing the items in a correct angle and put 5 or more items together on a hill. Could you please help me with this? Thanks, Regards.

• Allow Incoming Responses Apache. On Ubuntu 11.10 - Curl

  - by Daniel Adarve

  I'm trying to get a Curl Response from an outside server, however I noticed I cant neither PING the server in question nor connect to it. I tried disabling the iptables firewall but I had no success. My server is running behind a Cisco Linksys WRTN310N Router with the DD-wrt firmware Installed. In which I already disabled the firewall. Here are my network settings: Ifconfig eth0 Link encap:Ethernet HWaddr 00:26:b9:76:73:6b inet addr:192.168.1.120 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::226:b9ff:fe76:736b/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:49713 errors:0 dropped:0 overruns:0 frame:0 TX packets:30987 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:52829022 (52.8 MB) TX bytes:5438223 (5.4 MB) Interrupt:16 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:341 errors:0 dropped:0 overruns:0 frame:0 TX packets:341 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:27604 (27.6 KB) TX bytes:27604 (27.6 KB) /etc/resolv.conf nameserver 192.168.1.1 /etc/nsswitch.com passwd: compat group: compat shadow: compat hosts: files dns networks: files protocols: db files services: db files ethers: db files rpc: db files netgroup: nis /etc/host.conf order hosts,bind multi on /etc/hosts 127.0.0.1 localhost 127.0.0.1 callcenter # The following lines are desirable for IPv6 capable hosts ::1 ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters /etc/network/interfaces # The loopback network interface auto lo iface lo inet loopback # The primary network interface auto eth0 iface eth0 inet static address 192.168.1.120 netmask 255.255.255.0 network 192.168.1.1 broadcast 192.168.1.255 gateway 192.168.1.1 The Url to which im trying to get a connection to is https://www.veripayment.com/integration/index.php When I ping it on terminal heres what I get daniel@callcenter:~$ ping https://www.veripayment.com/integration/index.php ping: unknown host https://www.veripayment.com/integration/index.php daniel@callcenter:~$ ping www.veripayment.com PING www.veripayment.com (69.172.200.5) 56(84) bytes of data. --- www.veripayment.com ping statistics --- 2 packets transmitted, 0 received, 100% packet loss, time 1007ms PHP Function in codeigniter public function authorizePayment(){ //--------------------------------------------------- // Authorize a payment //--------------------------------------------------- // Get variables from POST array $post_str = "action=payment&business=" .urlencode($this->input->post('business')) ."&vericode=" .urlencode($this->input->post('vericode')) ."&item_name=" .urlencode($this->input->post('item_name')) ."&item_code=" .urlencode($this->input->post('item_code')) ."&quantity=" .urlencode($this->input->post('quantity')) ."&amount=" .urlencode($this->input->post('amount')) ."&cc_type=" .urlencode($this->input->post('cc_type')) ."&cc_number=" .urlencode($this->input->post('cc_number')) ."&cc_expdate=" .urlencode($this->input->post('cc_expdate_year')).urlencode($this->input->post('cc_expdate_month')) ."&cc_security_code=" .urlencode($this->input->post('cc_security_code')) ."&shipment=" .urlencode($this->input->post('shipment')) ."&first_name=" .urlencode($this->input->post('first_name')) ."&last_name=" .urlencode($this->input->post('last_name')) ."&address=" .urlencode($this->input->post('address')) ."&city=" .urlencode($this->input->post('city')) ."&state_or_province=" .urlencode($this->input->post('state_or_province')) ."&zip_or_postal_code=" .urlencode($this->input->post('zip_or_postal_code')) ."&country=" .urlencode($this->input->post('country')) ."&shipping_address=" .urlencode($this->input->post('shipping_address')) ."&shipping_city=" .urlencode($this->input->post('shipping_city')) ."&shipping_state_or_province=" .urlencode($this->input->post('shipping_state_or_province')) ."&shipping_zip_or_postal_code=".urlencode($this->input->post('shipping_zip_or_postal_code')) ."&shipping_country=" .urlencode($this->input->post('shipping_country')) ."&phone=" .urlencode($this->input->post('phone')) ."&email=" .urlencode($this->input->post('email')) ."&ip_address=" .urlencode($this->input->post('ip_address')) ."&website_unique_id=" .urlencode($this->input->post('website_unique_id')); // Send URL string via CURL $backendUrl = "https://www.veripayment.com/integration/index.php"; $this->curl->create($backendUrl); $this->curl->post($post_str); $return = $this->curl->execute(); $result = array(); // Explode array where blanks are found $resparray = explode(' ', $return); if ($resparray) { // save results into an array foreach ($resparray as $resp) { $keyvalue = explode('=', $resp); if(isset($keyvalue[1])){ $result[$keyvalue[0]] = str_replace('"', '', $keyvalue[1]); } } } return $result; } This gets an empty result array. This function however works well in the previous server where the script was hosted before. No modifications where made whatsoever Thanks in Advance

• Exchange 2003 resource scheduling with mixed client versions

  - by Daniel Lucas

  We run Exchange 2003, but have a mix of Outlook 2003/2007/2010 in the environment. We have three rooms that need to be configured as resources. Some observations we've made with resource scheduling/booking are: Outlook 2010 users have trouble with the native Exchange 2003 resource scheduling method and require direct booking to be configured via registry Outlook 2007 users are unable to use direct booking (is this accurate?) Outlook 2003 users can only use the native Exchange 2003 resource scheduling method (is this accurate?) Direct booking cannot be combined with the auto-accept agent What is the correct way to setup resource scheduling in a mixed environment like this? Thanks, Daniel

• rsync error: some files/attrs were not transferred

  - by Daniel Ball

  Using rsync(ubuntu) and a DeltaCopy server on W2K3 to back up some of the data on the file server before I migrate from W2K3 to Ubuntu server. After it completed I ran a dry run just in case something had been missed or changed ... I got the following: sudo rsync -az -n 198.3.9.25::Music /mnt/raid/music [sudo] password for daniel: file has vanished: "?????\#267????" (in Music) file has vanished: "????????" (in Music) ... rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1526) [generator=3.0.7] I just want to make sure I'm reading it right, that somehow there are files on the receiving end that aren't on the sending?

• How can I remove HTTP headers with .htaccess in Apache?

  - by Daniel Magliola

  I have a website that is sending out "cache-control" and "pragma" HTTP headers for PHP requests. I'm not doing that in the code, so I'm assuming it's some kind of Apache configuration, as suggested by this question (you don't really need to go there for this question's context) I don't have anything in my .htaccess files, so it's gotta be in Apache's configuration itself, but I can't access that, this is a shared hosting, I only have FTP access to my website's directory. Is there any way that I can add directives to my .htaccess files that will remove the headers added by the global configuration, or otherwise override the directive so that they're not added in the first place? Thank you very much Daniel

• Finding day of week in batch file? (Windows Server 2008)

  - by Daniel Magliola

  I have a process I run from a batch file, and i only want to run it on a certain day of the week. Is it possible to get the day of week? All the example I found, somehow rely on "date /t" to return "Friday, 12/11/2009", however, in my machine, "date /t" returns "12/11/2009". No weekday there. I've already checked the "regional settings" for my machine, and the long date format does include the weekday. The short date format doesn't, but i'd really rather not change that, since it'll affect a bunch of stuff I do. Any ideas here? Thanks! Daniel

• subversion: enforce TLS

  - by Daniel Marschall

  Hello, I am running subversion on a Debian Squeeze system with Apache2 and mod_dav for viewing the contents with a webbrowser. I want to enforce the usage of TLS, so that the login data and the SVN contents cannot be read from the connection. I have tried following: <Location /svn> DAV svn SVNParentPath /daten/subversion/ # our access control policy AuthzSVNAccessFile /daten/subversion/access_control # try anonymous access first, resort to real # authentication if necessary. Satisfy Any Require valid-user # how to authenticate a user AuthType Basic AuthName "Subversion repository" AuthUserFile /daten/subversion/.htpasswd # Test SSLRequireSSL RewriteEngine On RewriteCond %{SERVER_PORT} !443 RewriteRule ^svn/(.)$ https://www.viathinksoft.de/svn/$1 [R,L] </Location> at file /etc/apache2/conf.d/subversion.conf Alas, this does not work. There is no redirect and there is still a HTTP request working at /svn/(projectname)/(somefolder) . This SSL-enforce-policy should work for - viewing the contents with webbrowser - retrieve contents with TurtoiseSVN client - committing contents with TurtoiseSVN client Can you please help me? Regards Daniel Marschall

• Set up a root server using Ubuntu and Virtualization

  - by Daniel Völkerts

  Hello, I'd like to setup a fresh root server and install a linux based virtualization on it. My thoughts are on: Intel VTs Hardware Ubuntu 9.10 KVM based virt. The access to the root server will only be SSH for Administration. Has anybody done this before, what was your glues discovered in the daily use? My requirements are: very secure, so the root server only has ssh to the dom-0 and minimalistic ports for the guest (e.g. http/s). good monitoring of host/guest (my idea is to using zabbix for it) easy and fast administration (how are the command line tools working for you? cryptiv? high learning curve?) I'm pleased to learn from your suggestions. Regards, Daniel Völkerts
