• making "xwacom set" changes permanent

  - by Philippe

  On my Thinkpad X220 Tablet the touch-finger works flawlessly but the pen is terribly miscalibrated. The calibration tool in System settings - Wacom tablet does not work. Instead, whenever I wan't to use the pen I first need to sudo xsetwacom set 'Wacom ISDv4 E6 Pen stylus' Area 0 0 27760 15690 These changes do not remain permanent. That is, after every reboot they are gone. How can I make the change permanent - I'm not looking for a startup scrip, I'd like to set the right area once for all. Any idea?

• 2D collision resolving

  - by Philippe Paré

  I've just worked out an AABB collision algorithm for my 2D game and I was very satisfied until I found out it only works properly with movements of 1 in X and 1 in Y... here it is: public bool Intersects(Rectanglef rectangle) { return this.Left < rectangle.Right && this.Right > rectangle.Left && this.Top < rectangle.Bottom && this.Bottom > rectangle.Top; } public bool IntersectsAny(params Rectanglef[] rectangles) { for (int i = 0; i < rectangles.Length; i++) { if (this.Left < rectangles[i].Right && this.Right > rectangles[i].Left && this.Top < rectangles[i].Bottom && this.Bottom > rectangles[i].Top) return true; } return false; } and here is how I use it in the update function of my player : public void Update(GameTime gameTime) { Rectanglef nextPosX = new Rectanglef(AABB.X, AABB.Y, AABB.Width, AABB.Height); Rectanglef nextPosY; if (Input.Key(Key.Left)) nextPosX.X--; if (Input.Key(Key.Right)) nextPosX.X++; bool xFree = !nextPosX.IntersectsAny(Boxes.ToArray()); if (xFree) nextPosY = new Rectanglef(nextPosX.X, nextPosX.Y, nextPosX.Width, nextPosX.Height); else nextPosY = new Rectanglef(AABB.X, AABB.Y, AABB.Width, AABB.Height); if (Input.Key(Key.Up)) nextPosY.Y--; if (Input.Key(Key.Down)) nextPosY.Y++; bool yFree = !nextPosY.IntersectsAny(Boxes.ToArray()); if (yFree) AABB = nextPosY; else if (xFree) AABB = nextPosX; } What I'm having trouble with, is a system where I can give float values to my movement and make it so there's a smooth acceleration. Do I have to retrieve the collision rectangle (the rectangle created by the other two colliding)? or should I do some sort of vector and go along this axis until I reach the collision? Thanks a lot!

• In browser trusted application Silverlight 5

  - by Philippe

  With the new Silverlight 5, we can now have a In-Browser elevated-trust application. However, I'm experiencing some problems to deploy the application. When I am testing the application from Visual Studio, everything works fine because it automatically gives every right if the website is hosted on the local machine (localhost, 127.0.0.1). I saw on MSDN that I have to follow 3 steps to make it work on any website: Signed the XAP - I did it following the Microsoft tutorial Install the Trusted publishers certificate store - I did it too following the Microsoft Tutorial Adding a Registry key with the value : AllowElevatedTrustAppsInBrowser. The third step is the one I am the most unsure about. Do we need to add this registry key on the local machine or on the server ? Is there any automatic function in silverlight to add this key or its better to make a batchfile? Even with those 3 steps, the application is still not working when called from another url than localhost. Does anybody has successfully implemented a In-browser elevated-trust application? Do you see what I'm doing wrong? Thank you very much!

• JQuery SelectList Option Changed doesn't refresh

  - by Jean-Philippe

  Hi. I have this select list: <select url="/Admin/SubCategories" name="TopParentId" id="ParentList"> <option value="">Please select a parent category</option> <option value="1" selected="selected">New Store</option> <option value="2">Extensions</option> <option value="3">Remodel</option> <option value="4">Bespoke Signage</option> <option value="5">Tactical Signage</option> <option value="6">Size Chart</option> <option value="7">Contact Info</option> </select> As you can see the option 1 is marked as selected. When I change the selection, I use this code to do an ajax call to get some values to populate a new select list: $("#ParentList").unbind("change"); $("#ParentList").change(function() { var itemId = $(this).val(); var url = $(this).attr("url"); var options; $.getJSON(url, itemId, function(data) { var defaultoption = '<option value="0">Please select a sub-category</option>'; options += defaultoption; $.each(data, function(index, optionData) { var option = '<option value="' + optionData.valueOf + '">' + optionData.Text + '</option>'; options += option; }); $("#SubParentList").html(options); }); }); My problem is that whenever I change the selection, the itemId is always the id of option 1, because it is marked as selected. It doesn't pick up the value of the option it is being changed too. Can someone please enlighten me of their knowledge. Regards, Jean-Philippe

• Including a pyd directly in a setup.py file

  - by Philippe Beaudoin

  I have a complex build process to generate a couple of python extension modules (.pyd). I want to include these in my setup.py for use with distutils. The distutils page talks in length about how to add extension modules from source, but I'd want to simply package these precompiled .pyd. What is the best practice to do this? Eventually, I'd also like to freeze everything in an executable with py2exe. Will I be able to do this if I directly specify the .pyd?

• Making GWT application crawlable by a search engine.

  - by Philippe Beaudoin

  I want to use the #! token to make my GWT application crawlable, as described here: http://code.google.com/web/ajaxcrawling/ There is a GWT sample app available online that uses this, for example: http://gwt.google.com/samples/Showcase/Showcase.html#!CwRadioButton Will serve the following static webpage to the googlebot: http://gwt.google.com/samples/Showcase/Showcase.html?_escaped_fragment_=CwRadioButton I want my GWT app to do something similar. In short, I'd like to serve a different flavor of the page whenever the _escaped_fragment_ parameter is found in the URL. What should I modify in order for the server to serve something else (a static page, or a page dynamically generated through a headless browser like HTML Unit)? I'm guessing it could be the web.xml file, but I'm not sure. (Note: I thought of checking the Showcase app provided with the GWT SDK, but unfortunately it doesn't seem to support serving static files on _escaped_fragment_ and it doesn't use the #! token..)

• How to get rid of Internet Explorer 7 reloading on fragment change

  - by Philippe Beaudoin

  I have an anchor <a href="#!admin">General</a> somewhere in my page. Clicking this in any browser but IE7 (haven't tried IE6) causes no page reload, as expected. However, under IE7 it reloads the page as soon as it's clicked. The strangest thing is that I have the exact same anchor elsewhere in the page and it causes no reload. The only difference I can see between these is a slight difference in style, and the fact that the faulty anchor is deeply nested in divs, where the other is closer to the top. My questions: Is this a known bug with IE7? If so, is there any work around? If not, any clue as to what might be going wrong? Edit: If you want to see this yourself, go to http://filouguestbook.appspot.com/#!main sign-in with a google account and click on the Settings link the the top bar. Switch between the General and Accounts pages, the app will reload. From the Accounts page, click on Settings in the top bar, this will switch tab but not reload!

• How do I apply a servlet filter when serving an HTML page directly?

  - by Philippe Beaudoin

  First off, I'm using Google AppEngine and Guice, but I suspect my problem is not related to these. When the user connect to my (GWT) webapp, the URL is a direct html page. For example, in development mode, it is: http://127.0.0.1:8888/Puzzlebazar.html?gwt.codesvr=127.0.0.1:9997. Now, I setup my web.xml in the following way: <?xml version="1.0" encoding="UTF-8"?> <web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5"> <display-name>PuzzleBazar</display-name> <!-- Default page to serve --> <welcome-file-list> <welcome-file>Puzzlebazar.html</welcome-file> </welcome-file-list> <filter> <filter-name>guiceFilter</filter-name> <filter-class>com.google.inject.servlet.GuiceFilter</filter-class> </filter> <filter-mapping> <filter-name>guiceFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- This Guice listener hijacks all further filters and servlets. Extra filters and servlets have to be configured in your ServletModule#configureServlets() by calling serve(String).with(Class<? extends HttpServlet>) and filter(String).through(Class<? extends Filter) --> <listener> <listener-class>com.puzzlebazar.server.guice.MyGuiceServletContextListener </listener-class> </listener> </web-app> Since I'm using Guice, I have to configure extra filters in my ServletModule, where I do this: filter("*.html").through( SecurityCookieFilter.class ); But my SecurityCookieFilter.doFilter is never called. I tried things like "*.html*" or <url-pattern>*</url-pattern> but to no avail. Any idea how I should do this?

• Migrating from Apache2 to Lighttpd creating errors in PHP/mySQL?

  - by Jean-Philippe Murray

  Ok, I've been using basics ubuntu LAMP setups for years now, and I wanted to give lighttpd a try. My LAMP setup run in a virtual machine with scripts running just fine. So I created a new virtual machine, starting with a fresh install of ubuntu and made my setups. On this new VM, lighttpd + php works just fine. (Or at least it seems...) Problem occurs when I take the scripts from my LAMP setup and upload them to the new VM. I'm getting : Warning: mysql_real_escape_string(): Access denied for user 'www-data'@'localhost' (using password: NO) My lighttpd setup is configured as php-cgi but not my apache2 setup. Could this be the source of the problem? I think that scripts would be independent of the server configuration, so I doubt it. Also, I know that my DB connexion informations are good (as I can log in via phpmyadmin perfectly). I'm in the dark here, any pointers ? Thanks,

• Recovering OST file without profile

  - by Philippe

  We have a Microsoft Exchange Server 2007 and offer this solution to many customers. Recently, a customer had his personal Exchange server crash (which is what made him our customer). He called some technician to see if he could repair his server before calling us, but this said tech wasn't able to do anything for them. Now that all his mailbox are on our server, he would like to transfer his old emails over to the new profile, but the tech deleted all profiles on the client machines while trying to repair his Exchange server. So my customer still has the OST files but they are not related to any profiles. Is there any way to re-attach them to a profile, or to convert them into PST files that he could then import into his new profile? The only thing I found were third party software that could to the conversion, but I am wondering if Microsoft has any tools that could re-attach the OST to a new profile. I have also tried the scanpst.exe and scanost.exe to no avail. Thank you

• net use mapping not working in batch files but works in cmd

  - by Philippe

  Ok so here's the problem : I've got users using logon script in the domain (username.bat). The script simply lists 4 or 5 (net use letter: \\SERVER\directory\). However, when they open their session, the logon script doesnt work and returns system error 53 or 67 for all of them. I tried running the script after the profile has loaded and evrything is running, and it still gives me the error. I've then tried to run the same command in the cmd.exe. Everything mapped correctly. It also works fine if I map the drives using the "Tools Map network drives" utility. Is there anything that can prevent a command to work when ran in a batch-file but works correctly when typed in manually?

• Is there Powershell way to re-apply a restored password for the IIS IUSR account?

  - by Philippe Monnet

  On one of our IIS web servers the IUSR account suddenly expired or got corrupted, I recovered the password from the IIS metabase (using Cscript adsutil.vbs get w3svc\anonymoususerpass after switching IsSecureProperty = False). I then reset the password accordingly. Now I have to re-key that password on the Directory Security tab of all virtual directories (for the anonymous account) of all web sites on that server. Is there a way to automate this using Powershell? (I have searched so far in vain)

• How to manage processes-to-CPU cores affinities ?

  - by Philippe

  I use a distributed user-space filesystem (GlusterFS) and I would like to be sure GlusterFS processes will always have the computing power they need. Each execution node of my grid have 2 CPU, with 4 cores per CPU and 2 threads per core (16 "processors" are seen by Linux). My goal is to guarantee that GlusterFS processes have enough processing power to be reliable, responsive and fast. (There is no marketing here, just the dreams of a sysadmin ;-) I consider two main points : GlusterFS processes I/O for data access (on local disks, or remote disks) I thought about binding the Linux Kernel and GlusterFS instances on a specific "processor". I would like to be sure that : No grid job will impact the kernel and the GlusterFS instances Researchers jobs won't be affected by system processes (I'd like to reserve a pool of cores to job execution and be sure that no system process will use these CPUs) But what about I/O ? As we handle a huge amount of data (several terabytes), we'll have a lot of interuptions. How can I distribute these operations on my processors ? What are the "best practices" ? Thanks for your comments!

• Wordpress blog website apache and IIS subdirectory

  - by Philippe

  The issue is this : Our company has a website hosted on an IIS server. I have recently been given the task to configure a WordPress server for an eventual WordPress blog so that our social media employee could test and see how it works. This was completed successfully and easily on a new server and on a WAMP configuration. The website was published as wordpress.domain.com and works fine. HOWEVER! I have now been requested to ensure that the soon-to-go-online blog would be accessible through the address domain.com/blog. Is there a way to modify the original company website and simple redirect the /blog to the Apache WordPress website? If not, is there a way to transfer the wordpress.domain.com on the IIS server hosting the main website and keep the configuration? Is there a better solution that I haven't thought about (probably)? If so, what would you all suggest?

• Is there such thing as a portable database that runs easily OsX and Windows?

  - by Jean-Philippe Murray

  I need to make a small database for a project at school (not computer related at all, I'm indexing and categorizing paper documents of a research projet). The thing is that in september, my semester is over and other students will have to taker over the project (and so on, for every semester!), so I'd need something that would be free and OS agnostic (or at least OsX/Windows) so it would easily be given to the next students on the project. I was thinking about a WAMP running USB key that would have a MySQL / HTML interface, but it will become locked to the OS I choose first. LibreOffice and the likes will be an option in the end if I don't find anything truly portable. Anyone has a solution in mind?

• Any way to disable specific CPU sleep modes?

  - by Philippe

  I just got a new Toshiba Tecra S11 notebook, which has a Core i5 520M CPU, and it appears to suffer from a well-known problem: a high pitched noise when the CPU is idle. Googling around revealed that this is caused by a specific power-saving mode in the CPU. In most cases, C4 mode is blamed for the noise. So my question is: is it possible to disable C4 mode (or any other "sleep" mode) using some utility or BIOS setting? I don't mind if it hurts battery life. I'd appreciate any advice on this matter. It's driving me crazy.

• Where can I find a link to download the SP2 of OES2?

  - by Philippe

  Hi, I have a Netware Novell server with an eDirectory and different objects configured. I implemented an OEServer2 SP1 to emulate a DSfW to manage the eDirectory with AD. I join the domain with the Administrator login and I am logged as the Administrator domain. So far, there are no problems. When I open the MMC window on Windows Server 08 and snap in the "Active Directory Users and Computers" I can see all the OUs and objects presented in the Netware N. server. But, when I select some OUs I can have an error, and when I select other I don’t have this error. Error: “Data from XXXXX is not available from Domain Controller OES2.yyyy.local because: The server is unwilling to process the request. Try again later, or choose another DC by selecting Connect to Domain Controller on the Domain context menu.” With XXXX= OU’s name and yyyy.local= domain name and OES2 server name If somebody can upload this SP or post a link to download it... Thank you for your help!

• Script on startup without update-rc.d

  - by Jean-Philippe Blary

  I've a debian minimal installation, and I just want to start a script at startup. So, I've a script at /etc/init.d/myscript, I put a chmod 700, and create symlinks ('S20myscript') into /etc/rc2.d, rc3.d, rc4.d and rc5.d. But the script is NOT launched at all. When I put this script with update-rc.d (or insserv...), it works. I don't understand, am I forced to use this command? (and no, I don't want to use /erc/rc.local). Thanks!

• Route53 only for wildcard subdomain

  - by Philippe Gerber

  We recently moved our web application to AWS. One thing that is still managed by our old hoster is DNS. OLD HOSTER example.com. NS <Old hoster's name server> example.com. A <ElasticIP on EC2 instance> *.example.com. CNAME example.com. ... I'm now trying to setup and play around with Route53 and use it for name resolution of our EC2 instances. ROUTE53 web-01.aws.example.com. CNAME ec2-xx-xx-xx-xx.eu-west-1.compute.amazonaws.com. web-02.aws.example.com. CNAME ec2-xx-xx-xx-xx.eu-west-1.compute.amazonaws.com. ... Now my question: Is it possible to forward DNS queries for *.aws.example.com to Route53 (ns-xxxx.awsdns-59.co.uk.)? What kind of record would I have to add?

• I can access my company mail on iPhone, but not on a PC/Mac

  - by Philippe

  On my iPhone (4), I can set up my company e-mail, which allows me to receive and send e-mail and use the calender to manage appointments. The company is using Exchange 2003. The problem is that this is the only way I can access my e-mail when I'm not at the office. I've tried setting up an account on Outlook 2007, Outlook 2010, Outlook 2011 (Mac) and the OSX Mail app, but it doesn't work. The server cannot be reached, even though I've used the exact same settings as on the iPhone. The info I use on the iPhone is: Server name of the company mail server (it's the same as for webmail) Use SSL AD Domain of my account My AD account name Password When I enter this on the iPhone, it works like a charm, but whatever I try on one of my desktops, it doesn't work. FYI: I can't ask the company IT guys because according to them, it doesn't work from a remote location, not even on the iPhone (but obviously, that works just fine)

• git-receive-pack : command not found.

  I made a git repo on a local machine with "git init --bare" and added it as the remote origin on the project on my main computer with ssh: git add remote origin [email protected]:repoName.git I was able to make a commit and push from my main computer to the other computer the day I created the repo, but today i tried and it didn't work. When I did "git push origin" it returned this error: bash: line 1: git-receive-pack: command not found fatal: The remote end hung up unexpectedly The two machines are mac the main one running Leopard and the server one running Tiger.

• puppet execution of a python script where os.system(...) command is not working

  - by philippe

  I am trying to manage Unix users with puppet. Puppet provides enough tools to create accounts and provide authorized_keys files for instance, but no to set up user password, and it tell to the user. What I have done is a python script which generate a random password and send it to the user by email. The problem is, it is not possible to launch passwd Unix command with python, I have then written a bash script with the command: echo -ne "$password\n$password\n" | passwd $user passwd -e $user Launched manually, the script works fine and the created user has its password sent by email. But when puppet launches it, only the python script gets executed, as if the os.system('/bin/bash my_bash_script') is ignored. No error is displayed. And the user gets its password, but the passwd commands are not launched. Is there any limitation with puppet preventing to perform what I described? Or, how can I otherwise change the user account, its expiration, and send password by email? I can provide more information, but right now, I don't know which are accurate. Many thanks!

• zsh : How to list directory content with tab?

  - by Philippe CM

  I just switched from BASH to ZSH and thing are pretty good, but: when I start typing cd /usr/share/s and hit TAB, this is what I get : $ cd /usr/share/sane/ sane/ skype/ ssl-cert/ screen/ smplayer/ strigi/ seed-gtk3/ snmp/ synaptic/ sgml/ software-properties/ system-config-printer/ sgml-base/ soprano/ sysv-rc/ sgml-data/ sounds/ simple-scan/ splashy/ And this is ok. If I then hit TAB again, I get $ cd /usr/share/screen/, the next candidate, witch is also OK. (BTW, how do I cycle back to the previous candidate? Sorry, on to my question) Now what if I want to see the contents of /usr/share/screen/ now ? You now, BASH-style? The cursor is at the end of the line, will I have to ctrl-a (or home), then del del (to erase cd) then ls then ENTER? That seems like a lot of typing. (And it - possibly unnecessarily - enters the command in the history) Would not there be a key (maybe modifier-TAB? but the obvious candidates are already taken by the desktop... I digress) that would tell zsh to stop cycling through /usr/share/ and instead, just list the content /usr/share/screen/ ?
