• Thoughts on exception handling.

  - by AndyScott

  Was working on a windows form app (something I haven't done in a while), adding threading and logging so that it would work a little more smoothly and have a record of who did what.  I was just about at the point where I was going to check it into source control when I noticed that the Output window was showing "A first chance exception of type 'System.InvalidCastException' occurred in mscorlib.dll", so I googled it.  In reading some threads about the error, I came across the following comment and it got me thinking: "In addition, while they should be avoided if possible, exceptions are a quite legitimate part of program execution. It's their going unhandled that is a real issue, because that means crashy, crashy." How do you normally use exception handling?  I feel that exceptions are intended to handle errors in code (in my experience generally related to bad data making its way into the system).  Now don't get me wrong, I understand that exceptions happen and should be dealt with, but I feel that they are a "last resort" to keep a program from crashing, but should never be a way to pass data or continue logical processing that could be handled in standard code flow. I mention this, because I have seen it done. What do you think?

• 64kb limit on the size of MSMQ Multicast Messages

  - by John Breakwell

  When Windows 2003 came out, Microsoft introduced the ability to broadcast messages to any machines that were listening back. All you had to do was send out a message on a particular port and IP address and any client that had set up a Multicast queue with matching port and IP address would get a copy. Since its introduction, there have been a couple of security vulnerabilities that needed to be removed: Microsoft Security Bulletin MS06-052 Vulnerability in Pragmatic General Multicast (PGM) Could Allow Remote Code Execution (919007) Microsoft Security Bulletin MS08-036 Vulnerabilities in Pragmatic General Multicast (PGM) could allow denial of service (950762) The second of these, MS08-036, was resolved through an undocumented change in functionality. Basically, a limit of 64kb was put on the maximum size of a message that could be broadcast using the Multicast method. Obviously this has caused a few problems for any existing MSMQ Multicast applications that expected to be able to send larger messages. A hotfix has been developed to resolve this problem. 961605 FIX: Multicast messages larger than 64 kilobytes (KB) are not delivered as expected by using Message Queuing 3.0 after security update MS08-036 is installed A registry change is required: Open the registry with Regedit Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\RMCAST\Parameters\ Create a DWord called MaxpacketSize Set the value to the desired number of bytes. You can set it to a value between zero and 4MB. If you specify anything above 4MB, it will default to 64K. A reboot is needed after adding this value.

• How do I draw a dotted or dashed line?

  - by Gagege

  I'm trying to draw a dashed or dotted line by placing individual segments(dashes) along a path and then separating them. The only algorithm I could come up with for this gave me a dash length that was variable based on the angle of the line. Like this: private function createDashedLine(fromX:Float, fromY:Float, toX:Float, toY:Float):Sprite { var line = new Sprite(); var currentX = fromX; var currentY = fromY; var addX = (toX - fromX) * 0.0075; var addY = (toY - fromY) * 0.0075; line.graphics.lineStyle(1, 0xFFFFFF); var count = 0; // while line is not complete while (!lineAtDestination(fromX, fromY, toX, toY, currentX, currentY)) { /// move line draw cursor to beginning of next dash line.graphics.moveTo(currentX, currentY); // if dash is even if (count % 2 == 0) { // draw the dash line.graphics.lineTo(currentX + addX, currentY + addY); } // add next dash's length to current cursor position currentX += addX; currentY += addY; count++; } return line; } This just happens to be written in Haxe, but the solution should be language neutral. What I would like is for the dash length to be the same no matter what angle the line is. As is, it's just adding 75 thousandths of the line length to the x and y, so if the line is and a 45 degree angle you get pretty much a solid line. If the line is at something shallow like 85 degrees then you get a nice looking dashed line. So, the dash length is variable, and I don't want that. How would I make a function that I can pass a "dash length" into and get that length of dash, no matter what the angle is? If you need to completely disregard my code, be my guest. I'm sure there's a better solution.

• Best way to mask 2D sprites in XNA?

  - by electroflame

  I currently am trying to mask some sprites. Rather than explaining it in words, I've made up some example pictures: The area to mask (in white) Now, the red sprite that needs to be cropped. The final result. Now, I'm aware that in XNA you can do two things to accomplish this: Use the Stencil Buffer. Use a Pixel Shader. I have tried to do a pixel shader, which essentially did this: float4 main(float2 texCoord : TEXCOORD0) : COLOR0 { float4 tex = tex2D(BaseTexture, texCoord); float4 bitMask = tex2D(MaskTexture, texCoord); if (bitMask.a > 0) { return float4(tex.r, tex.g, tex.b, tex.a); } else { return float4(0, 0, 0, 0); } } This seems to crop the images (albeit, not correct once the image starts to move), but my problem is that the images are constantly moving (they aren't static), so this cropping needs to be dynamic. Is there a way I could alter the shader code to take into account it's position? Alternatively, I've read about using the Stencil Buffer, but most of the samples seem to hinge on using a rendertarget, which I really don't want to do. (I'm already using 3 or 4 for the rest of the game, and adding another one on top of it seems overkill) The only tutorial I've found that doesn't use Rendertargets is one from Shawn Hargreaves' blog over here. The issue with that one, though is that it's for XNA 3.1, and doesn't seem to translate well to XNA 4.0. It seems to me that the pixel shader is the way to go, but I'm unsure of how to get the positioning correct. I believe I would have to change my onscreen coordinates (something like 500, 500) to be between 0 and 1 for the shader coordinates. My only problem is trying to work out how to correctly use the transformed coordinates. Thanks in advance for any help!

• .htaccess rules to rewrite URLs to front end page?

  - by Dizzley

  I am adding a new application to my site at example.com/app. I want views at that URL to always open myapp.php. E.g. example.com/app -> example.com/app/myapp.php and example.com/app/ -> example.com/app/myapp.php What's the correct form of rewrite rules in the .htaccess file? I've got: <IfModule mod_rewrite.c> RewriteEngine On RewriteBase /app/ RewriteRule ^myapp\.php$ - [L] RewriteRule ^myapp.php$ - [L] RewriteRule . - [L] </IfModule> ...based on what the Wordpress front-end does. But all I see at example.com/app is a directory of files. :( (I put those rewrites at the top of my .htaccess file). Any ideas? Update What actually worked: RewriteEngine On RewriteBase / RewriteCond %{REQUEST_URI} ^/app(/.*)?$ [NC] RewriteCond %{REQUEST_FILENAME} !-f RewriteRule . /app/myapp.php [L] This is good because: Explicit or implicit calls to app/myapp.php work. example.com/app redirects to app/myapp.php example.com/app/ redirects to app/myapp.php example.com/app/subfunction redirects to app/myapp.php All other calls to example.com/otherstuff are untouched. Item 4 is Wordpress-like Front Controller pattern behaviour. I think that rule RewriteCond %{REQUEST_URI} ^/app.*$ [NC] needs refining as it allows /app-oh-my-goodness etc. through too. Thanks for the answers.

• Entity system in Lua, communication with C++ and level editor. Need advice.

  - by Notbad

  Hi!, I know this is a really difficult subject. I have been reading a lot this days about Entity systems, etc... And now I'm ready to ask some questions (if you don't mind answering them) because I'm really messed. First of all, I have a 2D basic editor written in Qt, and I'm in the process of adding entitiy edition. I want the editor to be able to receive RTTI information from entities to change properties, create some logic being able to link published events to published actions (Ex:A level activate event throws a door open action), etc... Because all of this I guess my entity system should be written in scripting, in my case Lua. In the other hand I want to use a component based design for my entities, and here starts my questions: 1) Should I define my componentes en C++? If I do this en C++ won't I loose all the RTTI information I want for my editor?. In the other hand, I use box2d for physics, if I define all my components in script won't it be a lot of work to expose third party libs to lua? 2) Where should I place the messa system for my game engine? Lua? C++?. I'm tempted to just have C++ object to behave as servers, offering services to lua business logic. Things like physics system, rendering system, input system, World class, etc... And for all the other things, lua. Creation/Composition of entities based on components, game logic, etc... Could anyone give any insight on how to accomplish this? And what aproach is better?. Thanks in advance, HexDump.

• Web development and tips for building a website and the advantages of using HTML 5 in the site

  - by Siddarth

  I am trying to make a website for my college, and the program starts from jan 13 and we get 15 days of time to develop a running site. The best site will become the college site. I am participating, for all these days i used to participate in C and C++ contests and also won a few contests, now i am really into web dev for the last 2 months. I knew HTML long ago recently i brushed up on it and learnt javascript from "javascript and jquery the missing manual"(sorry for not adding the link) and recently bought "PHP and MySQL web development" and I am going on fine with it, but still a lot of pages to cover in that book. After this what do i need to know ajax is one language to concentrate on, what else do i need to do to make this project up and running. Can someone let me know the tricks of this trade and complete information to build a site like this. Right now i am good with javascript HTML and CSS and thats it, what else I am studying HTML5 and CSS3 its pretty fast and neat. The info on site is a college website which includes students profiles where the have to register their info with college id number and pretty much thats it. Think of it as a college site + a social networking site for students, where they can upload there pics and videos pdf books etc.

• Multilingual sites and Google search results, using sub-folders for language

  - by AWinter

  About three months ago we added an English version of our, previously Japanese only, site under the subfolder /en/ we've tried to follow the sometimes incomplete best practices laid out by Google by adding alternate tags to all pages that are currently translated. The top page for instance has the following meta tags for language. <link rel="canonical" href="/"> <link rel="alternate" hreflang="ja" href="/"> <link rel="alternate" hreflang="en" href="/en/"> While the English main page under /en/ has <link rel="canonical" href="/en/"> <link rel="alternate" hreflang="ja" href="/"> <link rel="alternate" hreflang="en" href="/en/"> Alternate languages are setup in the sitemap. (as per Google's recommendations) It seems however that Google absolutely refuses to show the English top page in results when the user is using English at google.com if you search you'll, as of this post, get the Japanese description and a title that Google has apparently invented instead of the title and description in the meta-tags for the /en/ index page. Does anyone have any experience with subfolders actually working to affect search results? What are the best practices for ensuring that the correct language version of my website is displayed through Google and other search engines? And how long will it take before the new language version becomes prominent in search engine results?

• What should I do when the GETDEB repository is down?

• How can I properly create /dev/dvd?

  - by chazomaticus

  Certain programs look for /dev/dvd by default to find DVDs. When I first boot my computer without a DVD inserted, /dev/dvd exists and points to the correct place (/dev/sr0). However, when I insert a DVD, /dev/dvd disappears. I'd like it to stick around so I don't have to navigate to /dev/sr0 in programs that are looking for DVDs. How do I ensure that the /dev/dvd symlink exists and points to the right place? It looks like I can add something to /etc/udev/rules.d/70-persistent-cd.rules. This site gives a couple of examples, but the 70-persistent-cd.rules file says "add the ENV{GENERATED}=1 flag to your own rules", which isn't part of the examples. The man 7 udev page is impenetrable to me, and I'm not convinced the linked page gives 100% of the information I need. So, what can I do on a modern, Ubuntu 12.04 (or later) system to make /dev/dvd always exist and point to the right device? EDIT: Is it as simple as adding ENV{GENERATED}=1 to the rules in the linked page, something like this: SUBSYSTEM=="block", KERNEL=="sr0", SYMLINK+="dvd", GROUP="cdrom", ENV{GENERATED}=1 Is that the right information for modern Ubuntu? What is ENV{GENERATED} doing there, when it wasn't generated, but hand-written?

• install android sdk on kubuntu

  - by dot

  I'm trying to follow the instructions for installing the android sdk found here: http://developer.android.com/sdk/installing/adding-packages.html After i've unpackaged and i run the android program under tools, I don't get all the options that I'm supposed to. The only 2 folders that show up are tools, and extras. Under tools, it only shows the "Android SDK Tools" with the status "Installed". Under the "extas" folder, I have nothing. I've made sure that my http: proxy settings are correct. And I've checked the logs. there are no errors. According to the android developer site, I'm supposed to install the SDK platform tools. has anyone tried this on ubuntu? I also checked and saw others were instructed to do an apt-get install ia32-libs but it failed for me. Besides which, I am running the 32bit os... so I don't think i would need to install that... ??

• How to add display resolution fo an LCD in Ubuntu 12.04? xrandr problem

  - by SeregaI

  I am fresh for Ubuntu and Linux in general. I have installed Ubuntu 12.04 and stuck trying to setup correct resolution for my LCD display. The native resolution for the LCD is 1920x1080 here is the output from xrandr: $xrandr Screen 0: minimum 320 x 200, current 1280 x 720, maximum 4096 x 4096 LVDS1 connected 1280x720+0+0 (normal left inverted right x axis y axis) 0mm x 0mm 1280x720 60.0*+ 800x600 60.3 56.2 640x480 59.9 VGA1 disconnected (normal left inverted right x axis y axis) Then I create new modeline: $ cvt 1920 1080 60 1920x1080 59.96 Hz (CVT 2.07M9) hsync: 67.16 kHz; pclk: 173.00 MHz Modeline "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync So far so good. then I create new mode using xrandr: $ xrandr --newmode "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync But for some reason that new mode was created for VGA (VGA1) output instead of LCD output (LVDS1): $ xrandr Screen 0: minimum 320 x 200, current 1280 x 720, maximum 4096 x 4096 LVDS1 connected 1280x720+0+0 (normal left inverted right x axis y axis) 0mm x 0mm 1280x720 60.0*+ 800x600 60.3 56.2 640x480 59.9 VGA1 disconnected (normal left inverted right x axis y axis) 1920x1080_60.00 (0xbc) 173.0MHz <---------- ????!!!!!! h: width 1920 start 2048 end 2248 total 2576 skew 0 clock 67.2KHz v: height 1080 start 1083 end 1088 total 1120 clock 60.0Hz So, if I try to add mode to LVDS1, I get an error: $ xrandr --addmode LVDS1 "1920x1080_60.00" X Error of failed request: BadMatch (invalid parameter attributes) Major opcode of failed request: 149 (RANDR) Minor opcode of failed request: 18 (RRAddOutputMode) Serial number of failed request: 25 Current serial number in output stream: 26 Adding that new mode to VGA1 works fine, but I don't use that VGA1 output.

• What is a Coding Dojo?

  - by huwyss

  Recently i found out that there is a thing called "coding dojo". The point behind it is that software developers want to have a space to learn new stuff like processes, methods, coding details, languages, and whatnot in an environment without stress. Just for fun. No competition. No results required. No deadlines.Some days ago I joined the Zurich coding dojo. We were three programmers with different backgrounds.We gave ourselves the task to develop a method that takes an input value and returns its prime factors. We did pair programming and every few minutes we switched positions. We used test driven development. The chosen programming language was Ruby.I haven't really done TDD before. It was pretty interesting to see the algorithm develop following the testcases.We started with the first test input=1 then developed the most simple productive program that passed this very first test. Then we added the next test input=2 and implemented the productive code. We kept adding tests and made sure all tests are passed until we had the general solution.When we improved the performance of our code we saw the value of the tests we wrote before. Of course our first performance improvement broke several tests.It was a very interesting experience to see how other developers think and how they work. I will participate at the dojo again and can warmly recommend it to anyone. There are  coding dojos all over the world.Have fun!

• How to handle fine grained field-based ACL permissions in a RESTful service?

  - by Jason McClellan

  I've been trying to design a RESTful API and have had most of my questions answered, but there is one aspect of permissions that I'm struggling with. Different roles may have different permissions and different representations of a resource. For example, an Admin or the user himself may see more fields in his own User representation vs another less-privileged user. This is achieved simply by changing the representation on the backend, ie: deciding whether or not to include those fields. Additionally, some actions may be taken on a resource by some users and not by others. This is achieved by deciding whether or not to include those action items as links, eg: edit and delete links. A user who does not have edit permissions will not have an edit link. That covers nearly all of my permission use cases, but there is one that I've not quite figured out. There are some scenarios whereby for a given representation of an object, all fields are visible for two or more roles, but only a subset of those roles my edit certain fields. An example: { "person": { "id": 1, "name": "Bob", "age": 25, "occupation": "software developer", "phone": "555-555-5555", "description": "Could use some sunlight.." } } Given 3 users: an Admin, a regular User, and Bob himself (also a regular User), I need to be able to convey to the front end that: Admins may edit all fields, Bob himself may edit all fields, but a regular User, while they can view all fields, can only edit the description field. I certainly don't want the client to have to make the determination (or even, for that matter, to have any notion of the roles involved) but I do need a way for the backend to convey to the client which fields are editable. I can't simply use a combination of representation (the fields returned for viewing) and links (whether or not an edit link is availble) in this scenario since it's more finely grained. Has anyone solved this elegantly without adding the logic directly to the client?

• Updating Google sitemap for mobile

  - by dimo414

  I have a series of utilities to generate Google sitemaps for my whole site. These files are massive, and slow to build. We want to start telling Google these pages are mobile-crawl-able too, by adding them to mobile sitemaps, but the documentation is unclear if I need to specify physically different files for my mobile URLs than for my normal ones. If this is my current sitemap: <?xml version="1.0" encoding="UTF-8" ?> <urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"> <url> <loc>http://mobile.example.com/article100.html</loc> </url> </urlset> Can I simply change it to: <?xml version="1.0" encoding="UTF-8" ?> <urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9" xmlns:mobile="http://www.google.com/schemas/sitemap-mobile/1.0"> <url> <loc>http://mobile.example.com/article100.html</loc> <mobile:mobile/> </url> </urlset> Or do I need to create new files with the additional markup, alongside my existing files?

• Is Wordpress more appropriate than Magento/Opencart for site like this?

  - by Alex

  The premise of the site is that a user pays a small fee to advertise an item that they want to sell. Therefore the user is responsible for adding the "products", not the administrator. The product upload will create a product page for that item. This is a rather common framework that I'm sure you're familiar with. My initial thought was that it would be best suited using Magento - mainly because it needs to accept payments - and the products will grow to form a catalog of categorized products. However - there is no concept of a shopping cart. A buyer does not buy the item online, or go to a checkout. They simply look at the product, and contact the seller if they like it. The buyer and seller then take it from there. For this reason, I then begin to suspect that Magento is perhaps too overkill, or just simply not the right CMS if there is on checkout procedure (other than the uploader making a payment) So then I begin to think Wordpress....Hmmm Feature requirements: User's can add content via a form process User's can be directed to a payment gateway For each product listing - a series of photographs shall be displayed, in thumbnail form Zoom capabilities/rotate on the images would be a welcome feature In short - e-commerce CMS, or something more simple?

• Unsure about TRIM enabled on my SSD

  - by user84750

  I have a SSD OCZ Vertex4 installed on my laptop. I'm running Ubuntu 12.04 LTS. I have enable TRIM by adding "discard" to my fstab file. (also added option noatime). I rebooted my Ubuntu and followed These instructions here to test TRIM. The end results of my tempfile was all ffff's, when it should have read all zero's, which is telling me TRIM is not really working or enabled correctly. Did I miss something? Also, will it be a problem if only my /home directory is encrypted. AND if you ask why I have swap on my SSD, it's because I let Ubuntu set up my partition. When I have my SSD, I just wanted to install Ubuntu as fast as possible. =) I've done testing to see at which point it will start to use swap and it took a lot of applications open to finally use swap. I currently have 4 GB of memory. I might shrink this to like 512 MB or 1 GB the most. Here's some info about my file system setup. sudo hdparm -I /dev/sda1 | grep "TRIM supported" Data Set Management TRIM supported (limit 16 blocks) sudo fdisk -l /dev/sda Device Boot Start End Blocks Id System /dev/sda1 * 2048 242016255 121007104 83 Linux /dev/sda2 242018302 250068991 4025345 5 Extended /dev/sda5 242018304 250068991 4025344 82 Linux swap / Solaris ls /dev/mapper control cryptswap1

• Calendar issue in simple java form using swing package?

  - by Rand Mate

  I have created a form using java swing package, For the purpose of adding Date of Birth in the form I have used the following code particularly to add in java Frame via Swing Package. Is there any alternative way to simplify the code. JLabel l2 = new JLabel("Date of Birth"); l2.setBounds(200,160,100,20); String day[] ={"1","2","3","4","5","6","7","8","9","10","11","12","13","14","15","16","17","18","19","20","21","22","23","24","25","26","27","28","29","30"}; String month[] = {"Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"}; String year[] = {"2012","2011","2010","2009","2008","2007","2006","2005","2004","2003","2002","2001","2000","1999","1998","1997","1996","1995","1994","1993","1992","1991","1990","1989","1988","1987","1986","1985","1984","1983","1982","1981","1980","1979","1976","1975"}; JComboBox cb1 = new JComboBox(day); cb1.setBounds(450,160,50,20); JComboBox cb2 = new JComboBox(month); cb2.setBounds(500,160,50,20); JComboBox cb3 = new JComboBox(year); cb3.setBounds(550,160,60,20);

• Would form keys reduce the amount of spam we receive?

  - by David Wilkins

  I work for a company that has an online store, and we constantly have to deal with a lot of spam product reviews, and bogus customer accounts. These are all created by automated systems and are more of a nuisance than anything. What I am thinking of (in lieu of captcha, which can be broken) is adding a sort of form key solution to all relevant forms. I know for certain some of the spammers are using XRumer, and I know they seldom request a page before sending us the form data (Is this the definition of CSRF?) so I would think that tying a key to each requested form would at least stem the tide. I also know the spammers are lazy and don't check their work, or they would see that we have never posted a spam review, and they have never gained any revenue from our site. Would this succeed in significantly reducing the volume of spam product reviews and customer account creations we are seeing? EDIT: To clarify what I mean by "Form Keys": I am referring to creating a unique identifier (or "key") that will be used as an invisible, static form field. This key will also be stored either in the database (relative to the user session) or in a cookie variable. When the form's target gets a request, the key must be validated for the form's data to be processed. Those pesky bots won't have the key because they don't load the javascript that generates the form (they just send a blind request to the target) and even if they did load the javascript once, they'd only have one valid key, and I'm not sure they even use cookies.

• XNA 2D Spritesheet drawing rendering problem

  - by user24092

  I'm making a tile-based game, using one spritesheet containing all tile graphics. Each tile has a size of 32x32 pixels. The main problem is: when I draw the tile to the screen, if the tile position x and y are not rounded or if scale is activated in spriteBatch.Draw() method (scale != 1.0f), I get some lines of adjacent tiles on the spritesheet into the current tile drawed. I already tried setting SamplerState to PointClamp, removing AntiAlias, but still doesn't work. Here I'll show images of some tests that I made, with a test sprite sheet that I've created (I made a 9x9 spritesheet, with each sprite of size 32x32 containing a unique solid color). Tests: http://img6.imageshack.us/img6/5946/testsqj.png SpriteSheet used: http://imageshack.us/a/img821/1341/tilesm.png Already tried to remove anti-alias, set PointClamp as sampler state, but still getting this issue, XNA keeps drawing part of the adjacent pixels of the texture on the screen. What I want is to get the correct area of the tilesheet texture (as seen in the first test, that gets just the yellow pixels). My question is: Is there any way that I can fix this, WITHOUT adding tile spacing or any other modification involving the tilesheet? Maybe disabling a texture filtering that is done by XNA, or something like that.

• USB mouse pointer only moving horizontally on macbook 6.2 with 12.04

  - by Glyn Normington

  After installing Ubuntu 12.04 on a macbook pro 6.2, the touchpad and external USB mouse worked perfectly. After rebooting I can't get either touchpad or external USB mouse to work. Sometimes no mouse pointer is visible, but more often I can only move the mouse pointer horizontally five sixths of the way across the display (from the top left). I have uninstalled mouseemu. xinput list shows the USB mouse. xinput query-state for the USB mouse shows the following: ButtonClass button[1]=up ... button[16]=up ValuatorClass Mode=Relative Proximity=In valuator[0]=480 valuator[1]=2400 valuator[2]=0 valuator[3]=3 and re-issuing this command with the pointer at its right hand extreme displays the same except for: valuator[0]=1679 So the valuator[0] seems to be the x-coordinate of the pointer and the range of motion 480-1679 is indeed about five sixths of the display width (1440). valuator[1] is suspiciously large given the display height is 900. Perhaps this is a side-effect of having previously been using a dual monitor (although booting with that monitor connected does not help). There are other entries listed under xinput list: Virtual core XTEST pointer which seems stuck at position (840,1050). bcm5974 which seems stuck at position (837,6700). Removing the bcm5974 module using rmmod disables the toucpad as expected but does not fix the USB mouse problem. After adding the module back, it is stuck at position (840,1050) instead of (837,6700). /etc/X11/xorg.conf was generated by nvidia-settings and contains: Section "InputDevice" # generated from default Identifier "Mouse0" Driver "mouse" Option "Protocol" "auto" Option "Device" "/dev/psaux" Option "ZAxisMapping" "4 5" although I don't know how plausible these settings are. Any suggestions?

• Is ZeroMQ a good choice to make a Python app and a C# managed assembly work together?

  - by Alex Bausk

  I have a task that involves talking to a .NET-based API (namely AutoCAD) to retrieve data, send commands, and react to events. I want to separate the API operations and the proper program logic (largely already implemented in Python) by using natural tools for both: a C# DLL for the former and a Python app for the latter. To connect these two pieces, I began exchanging JSON in ZeroMQ messages. I'm at early development stages but having recently discovered that ZeroMQ does not guarantee message delivery/order, I have reservations about whether this is a feasible way to go. Right now my app is a very basic REQ/REP pair and I plan to handle reacting to events and executing different commands by adding some sort of 'recipient-function' field to my message format. The reason that I want to use ZMQ is that I might be able to scale the software into a larger, multi-user, distributed solution sometime. I am a lay programmer so I would ask for your advice about this architecture. Should I just go ahead with it and plan to deal with message reliability/ordering when problems appear? Should I consider developing some kind of a REST wrapper around ZMQ?

• How can I choose a Webapp UI Design/dev collaborative tool?

  - by Cheeso

  I am working with a team that's building a webapp for internal use in an enterprise. It's basically a workflow app at heart, where there's a single "request". Each request flows through various stages, and at each stage, there's a person or role that is responsible for moving the request to the next stage. "Moving" the request to the next stage might involve adding more data, validating things, gathering input from some external source and correlating it to the data in the request, and so on. The workflow engine has been selected. The UI for the various roles and stakeholders is being designed. We have a distributed group of stakeholders. I'd like to employ a collaborative design/dev effort, where devs can produce and stand-up mockups or even working prototypes, then solicit feedback on those things. In a centralized team this could be done via design review meetings, with everyone gathered round a screen projector. That just is not going to work for us. So what I'd like is an app that can help with this. Any recommendations on apps or how to choose?
