• Problem when scaling game screen in Libgdx

  - by Nicolas Martel

  Currently, I'm able to scale the screen by applying this bit of code onto an OrthographicCamera Camera.setToOrtho(true, Gdx.graphics.getWidth() / 2, Gdx.graphics.getHeight() / 2); But something quite strange is happening with this solution, take a look at this picture of my game below Seems fine right? But upon further investigation, many components are rendered off by one pixels, and the tiles all are. Take a closer look I circled a couple of the errors. Note that the shadow of the warrior I circled appears fine for the other warriors. Also keep in mind that everything is rendered at pixel-perfect precision when I disable the scaling. I actually thought of a possible source for the problem as I'm writing this but I decided to still post this because I would assume somebody else might run into the same issue.

• WebCenter Content Web Search Performance: Do you really need that folder path info?

  - by Nicolas Montoya

  End-users want content at their fingertips at the speed of thought if possible. When running search operations in the WebCenter Conter Web Interface every second or fraction of a second improvement does matter. When doing some trace analysis on the systemdatabase tracing on a customer environment, we came across some SQL queries that were unnecessarily being triggered! These were related to determining the folder path for every entry part of the search result set. However, this folder path was not even being used as part of the displayed information in the user interface.Why was the folder path information being collected when it was not even displayed in the UI? We found that the configuration parameter 'FolderPathInSearchResults' was set to 'true' under Administration > Admin Server > General Configuration > Additional Configuration Variables as shown below:When executing a quicksearch by keyword we were getting 100 out of 2280 entries in the first page of the result set.When thera 'FolderPathInSearchResults' configuration parameter is set to 'true', the following queries appear in the systemdatabase tracing:100 executions for a query on the FolderFiles table for each of the documents displayed in the first page:>systemdatabase/6       12.13 11:17:48.188      IdcServer-199   1.45 ms. SELECT * FROM FolderFiles WHERE dDocName='SLC02VGVUSORAC140641' AND fLinkRank=0[Executed. Returned row(s): true]382 executions for a query of the folders tables - most of the documents that match the keyword criteria are at a folder depth level of three or four:>systemdatabase/6       12.13 11:17:48.114      IdcServer-199   2.57 ms. SELECT FolderFolders.*,FolderMetaDefaults.* FROM FolderFolders,FolderMetaDefaults WHERE FolderFolders.fFolderGUID=FolderMetaDefaults.fFolderGUID(+) AND((FolderFolders.fFolderGUID = '1EB8E527E19B09ED3FE82EE310AEA13A' ) )[Executed.Returned row(s): true]By setting this 'FolderPathInSearchResults' configuration parameter to 'false', the above queries were no longer reported in the Server Output System Audit Information.Now, let's consider a practical scenario:Search result set page = 100Average folder depth der document in the search result set: 5The number of folder path related queries will be: 100 + 5*500 = 600If each query takes slightly over 3 ms. You would have 2000 ms (2 seconds) spent in server time to get this information.The overall performance impact goes beyond seerver time execution, as this information needs to travel from the server to the browser. If the documents are further nested into the folder hierarchy, additional hundreds of queries may be executed. If folder path is not being displayed in the end-user interface profile, your system may be better of with the 'FolderPathInSearchResults' configuration parameter disabled.

• Upgrade to 12.04, nothing in dash, no date&time

  - by Nicolas

  I've upgraded from ubuntu netbook remix something to 12.04 lts, and I've got two issues. (Got an Asus eeePc 32bits, Intel 945GME x86/MMX/SSE2 and Intel Atom CPU N270 @ 1.6Ghz x2) Nothing in the dash. Only the "home" tab, other tabs are missing. No search result whatsoever. Missing elements in the system panel, privacy and date&time. No date&time on the right corner either. I've tried to reset unity with the terminal but the process was a whole mess full of errors. It did show date&time in the system panel (not on the top-right corner) while the process was going on in the terminal. But then it was such a mess (no more icons on the right corner amongst other things), and the process wouldn't complete: so I had to reboot the computer and get unity as before, still no date&time and privacy. Thanks for any help. nic

• How to simulate a USB plug?

  - by Nicolas Delvaux

  I have an app that implements some automations when an USB key is plugged. While developing, I have to test it in a specific environment (derivative from Debian Squeeze). The app subscribe to HAL events via DBUS. The problem is: my desk is on the third floor while my test machines are in the basement. I would really like to have a way to simulate a USB plug. usbip does not work on Ubuntu. I can't manage to use the g_mass_storage module on Ubuntu (I lack the dummy_hcd module) and in Debian. Maybe it is possible to simulate a dbus call? My work station is on Ubuntu 12.04.

• Which CMS can I use for my project?

  - by Nicolás A.

  I have to build a new website for my client.. and he needs this stuff: A user generated content website.. where users can upload their own videos.. (i will use a video hosting platform with api like fliqz.com) I must manage a big user system.. where users can create their own "sub-users"... the site must manage paid subscriptions and payments through paypal.. and other payment gateways... So the question is.. i have to use a pre-built CMS and extend it.. or just a good framework? I've been thinking about joomla, drupal and expressionengine... It's not neccesary to use a open source cms... I've looking at drupal.. but is not as easy to understand and extend... Can anyone help me to make a good decision?

• How to setup VPN as Proxy

  - by Nicolas Nox

  I have an PerfectPrivacy VPN connected via the OpenVPN-Network-Manger-Plugin (Ubuntu 12.04.1) and I want to assign a system wide proxy over that VPN. I have tried proxydriver that should do that automatically, but it works partially. The browser says that I have the IP of the VPN, but when I tried to send an eMail over SMTP (Port 25), I can´t connect to the mail server. In our company the smtp server port is closed, but that should be not a problem, when I do that over a VPN, shouldn´t it? greetings

• List of backlinks to a specific website, listed by decreasing PageRank

  - by Nicolas Raoul

  With backlinkwatch.com I can get a list of pages that link to a particular website. Unfortunately, it lists tons of obscure blogs and small forums, it has hard to find what link is really important. Is there a similar service, where links would be displayed sorted by "importance"? For instance, a link New York Times would be shown at the top of the list, while links in small blogs would not appear before a few pages. "Importance" can be subjective, so I suggest using the PageRank, but other metrics could be fine too.

• Paypal (sandbox) buy now link redirects to paypal (sandbox) login page instead of order summary

  - by Nicolas

  Hi, Before going live I try to test the paypal process against the paypal sandbox mode, but after the summary of what the user is going to pay on my website(buy now button), the link does not redirect to a paypal summary of the prder but ask the user to connect to paypal. Even after logging into the buyer sandbox account there's no summary of the order. It just disappears. Here's is the code I use on the checkout page: <form action="https://www.sandbox.paypal.com/cgi-bin/webscr" method="post"> <input type="hidden" name="cmd" value="_s-xclick"> <input type="hidden" name="hosted_button_id" value="XXXXXXXXXXXXXXXX"> <input type="hidden" name="notify_url" value="http://www.website.com/paypal/"> <div class="suggestion"> <input type="image" src="https://www.sandbox.paypal.com/en_GB/i/btn/btn_paynowCC_LG.gif" border="0" name="submit" alt="PayPal - The safer, easier way to pay online!"> <img alt="" border="0" src="https://www.sandbox.paypal.com/en_GB/i/scr/pixel.gif" width="1" height="1"> </div> </form> Any idea why it redirects to the payapl login page instead of the order one? Btw I'm using the Website Basic Payment (not PRO then). Cheers, Nicolas.

• searching article for names in the database before submitting article to the database

  - by zurna

  I want to create a function that will search through a text, find names those match with existing names in the database and add links to those names before submitting the article to the database. i.e. text: Chelsea are making a change now as goalscorer Nicolas Anelka is replaced by in-form Florent Malouda who can do no wrong lately. Nicolas Anelka exists in the database in the Players table with ID column equals to 1. I want text to be converted to Chelsea are making a change now as goalscorer Nicolas Anelka is replaced by in-form Florent Malouda who can do no wrong lately. I know my code is logically wrong but I could build the correct logic.

• Bring the windows of two different apps in mac os to the front?

  - by Nicolas Kokkalis

  How do I easily bring to the front of the screen the top windows of two different application in Mac OS X? I prefer to use the keyboard only. Example Scenario: Say there are 10 Firefox and 10 TextEdit windows open. Also, say that these windows are having various different sizes so that the windows of each application fully cover the desktop. Goal: I want to bring to the front of my screen the top window of Firefox along with the top window of TextEdit, so that I can visually compare some data. Restrictions: I cannot use expose (since having 20 windows on the screen already renders expose useless) And I do not want to use multiple desktop (too complex and time consuming) I prefer to use a keyboard shortcut. Unfortunately cmd+tab brings all windows of each application to the top, covering all windows of the other applications.

• Installing gitosis and closed port?

  - by Nicolas GUILLAUME

  I'm trying to install gitosis on a Server (hosted by OVH and running Ubuntu server 11.04). I've done it a few times and never had any problems. But this time I have something very wired when I simply try to clone gitosis. [root@ovks-1:~/]#git clone git://eagain.net/gitosis.git Cloning into gitosis... eagain.net[0: 208.78.102.120]: errno=Connection refused fatal: unable to connect a socket (Connection refused) zsh: exit 128 git clone git://eagain.net/gitosis.git Based on my searches it looks like the port 9418 is closed. But I don't understand, a server by definition shouldn't have any closed port and I can't find a way to see if they are. So how can I check is a port is open and how can I open it if closed? Thank you for your help. Requested by WesleyDavid: iptables -L result [root@odeoos-vks-1:~/]#iptables -L Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination I have no idea what it means... Thanks :)

• Buying replacement Macbook Pro Battery - Genuine vs. eBay

  - by Nicolas Webb

  I'm looking to replace my Macbook Pro's battery (15", last model before the Unibody). It's currently at 55% capacity (as reported in System Information and Battery Health Monitor). I've reset the SMC firmware, calibrated the battery, and it's just not lasting that long anymore. I've seen some genuine replacements that are "pulls" (pulled from used computers) that are rated at least 90% capacity (iFixit, MacSales). I've also seen a variety of batteries on eBay that look more like clones than genuine batteries, but are new. A new battery from Apple is $129, and when I brought my laptop in they ran the Battery test and said if I bought the battery right then they'd give me a discount (around $100). Anyone out there used one of these "OEM Compatible" batteries? Fit/finish good? (I don't want a funky color or a corner that sticks out.) Or, should I just suck it up and get the genuine replacement (for about twice the price)?

• VM image including ready-to-use Kerberos server?

  - by Nicolas Raoul

  I implemented client-side Kerberos support to an open source software, and I want to test it. I don't have a Kerberos network at home and unfortunately don't have the skills/time to reliably set up one. Is there a Virtual Machine image that I could fire up, and that would include a properly working Kerberos environment, so that I can test my client app? (freely downloadable Linux/Microsoft/anything all acceptable)

Does anyone knows how to use LESS files with NGINX ?

• pam_filter usage prevent passwd from working

  - by Henry-Nicolas Tourneur

  Hello everybody, I have PAM+LDAP SSL running on Debian Lenny, it works well. I always want to restrict who's able to connect, in the past I used pam_groupdn for that but I recently got a situation where I has to accept 2 different groups. So I used pam_filter like this : pam_filter |(groupattribute=server)(groupattribute=restricted_server) The problem is that with this statement, passwd doesn't work anymore with LDAP accounts. Any idea why ? Please find hereby some links to my config files : Since serverfault.com only allow me to post 1 link, please find hereunder the link to other conf files : http://pastebin.org/447148 Many thanks in advance :)

• Rsyslog mail module not working

  Hi *, I would like to email snort alerts from my Debian Lenny fw. Syslog is sending log messages from the firewalls to a central rsyslog. On my central rsyslog, I got something like : $ModLoad ommail $ActionMailSMTPServer server.company.local $ActionMailFrom [email protected] $ActionMailTo [email protected] $ActionExecOnlyOnceEveryInterval 1 $template mailSubject,"[SNORT] Alert from %hostname%" $template mailBody,"Snort message\r\nmsg='%msg%'" $ActionMailSubject mailSubject if $msg regexp 'snort[[0-9]]: [[0-9]:[0-9]:[0-9]].*' then ommail:;mailBody But I doesn't get any mails, I even can trigger snort with something like ping -s 1400, it logs things like following but still no mail ! 2010-01-08T09:25:58+00:00 Hostname snort[4429]: [1:499:4] ICMP Large ICMP Packet [Classification: Potentially Bad Traffic] [Priority: 2]: {ICMP} ip_dest - ip_src Any idea ?

• Cadaver with Kerberos: 401 Unauthorized

  How to make Cadaver connect to a WebDAV server that uses Kerberos authentication? Usually cadaver http://localhost:8080/alfresco/webdav works, I can browse files, but on a network with Kerberos I get: Could not open collection: 401 Unauthorized Even though I have logged in with kinit successfully and have a valid ticket. I can see that Kerberos support has been implemented in Cadaver in 2005. Is there a special syntax to use? No info in the man.

• Enabling Multiple Monitor Support from Terminal Services/Remote Desktop over Citrix

  - by Nicolas Webb

  Our Remote Desktop/Terminal Services solution where I work relies on Citrix for machines not connected via the VPN. We're using Citrix Xen server (I'm pretty sure) and I'm going to try to connect to a Windows 7 Host (my work computer) and I think the RDC client runs on a Win2003 host (exposed via Citrix). Is it possible to take advantage of Windows 7 multiple monitor support for RDC with this setup? Would I need to try getting my Citrix guys to have a different host machine for the RDC (Win2008, or Win7?)? I'm probably going to connect using the OS X Citrix client, but I'd be willing to BootCamp/Fusion up a Windows instance to work remotely, as well. I really want to be able to use multiple monitors remotely. It does "span" multiple montiors currently (I have a 3000x1024 desktop, for example) but I'd rather it be "true" multiple monitor instead of one giant desktop, if possible.

• Instabilities with Bridged and bonded interfaces

  - by Henry-Nicolas Tourneur

  I did post yesterday to get a working setup with several bridged interfaces used for virtual machines (KVM/libvirt). One of the bridged interface is just using eth3 as its ports while the second one (public traffic) is using an ethernet bonded interface. That setup is working but not all the time ! I can start a download from a vm, then it will stop and freeze! So I don't know if my bridge parameters are correct, could you check the below config ? iface eth3 inet manual auto bond0 iface bond0 inet manual slaves eth1 eth2 pre-up ip link set bond0 up down ip link set bond0 down auto br0 iface br0 inet static address 10.160.0.7 netmask 255.255.255.128 bridge_ports eth3 bridge_fd 9 bridge_hello 2 bridge_maxage 12 bridge_stp on auto br0:1 iface br0:1 inet static address 10.160.0.9 netmask 255.255.255.255 auto br0:2 iface br0:2 inet static address 10.160.0.10 netmask 255.255.255.255 auto br1 iface br1 inet static address 217.4.40.242 netmask 255.255.255.240 gateway 217.4.40.241 pre-up /etc/network/firewall start bridge_ports bond0 bridge_fd 9 bridge_hello 2 bridge_maxage 12 bridge_stp on auto br1:1 iface br1:1 inet static address 217.4.40.252 netmask 255.255.255.255 auto br1:2 iface br1:2 inet static address 217.4.40.253 netmask 255.255.255.255 And yes, it also sometimes speaks about martian on the host: kernel: [249146.055172] martian source 10.160.0.17 from 10.160.0.10, on dev vnet2 kernel: [249146.073122] ll header: ff:ff:ff:ff:ff:ff:54:52:00:76:c3:5c:08:06
