  • How do you get better working conditions? [closed]

    - by 0A0D
    I work at a business who has a software side and manufacturing side. The software we write is sold as a package along with other hardware that our customers purchase. I basically work in a warehouse. There is one door that seperates the engineers from the warehouse noise. I have asked for noise cancelling walls to be put in. I have asked multiple times over 6 months to be moved up front to one of two vacant sales offices, but they seem reluctant to let an Engineer move into a sales office. In fact, sales are the only ones with windows and they get commission though they make mistakes or overpromise to the customer. So, my question is how can I get better working conditions without necessarily having to leave my current job? It is very hard to work and concentrate. UPDATE I think I can finally close this chapter in my life. I have moved on to a large corporation which follows CMMI religiously and has even started using Agile in many of its projects. Nevertheless, there is organization, respect, and genuine care for the engineers and scientists that work for them. Pierre was right - quitting was the right answer. My life does not nearly have the amount of stress it used to have because I now work for a place that is organized and knows what it wants its engineers to do along with treating them like they should be treated.

  • How do I require use of the 5 GHz band when connecting to a Wireless N access point?

    - by cqcallaw
    What is says in the topic: there's a Wireless N access point to which I'd like to connect using the 5 GHz band exclusively. How does one accomplish this? Using the directive band=a in the connection configuration file in /etc/NetworkManager/system-connections doesn't seem to affect anything (/var/log/syslog still shows attempts by wpa_supplicant to connect using the 2.4 GHz band), and running iwconfig wlan0 freq 5G per this question results in the following error: Error for wireless request "Set Frequency" (8B04) : SET failed on device wlan0 ; Invalid argument. [Edit] I'm hoping the answer won't depend on the hardware in use, but here's some information about the hardware, just in case: System is an Asus ZenBook Prime UX31A-DB51, running Ubuntu 12.04. lspci output: 00:00.0 Host bridge: Intel Corporation Ivy Bridge DRAM Controller (rev 09) 00:02.0 VGA compatible controller: Intel Corporation Ivy Bridge Graphics Controller (rev 09) 00:04.0 Signal processing controller: Intel Corporation Device 0153 (rev 09) 00:14.0 USB controller: Intel Corporation Panther Point USB xHCI Host Controller (rev 04) 00:16.0 Communication controller: Intel Corporation Panther Point MEI Controller #1 (rev 04) 00:1a.0 USB controller: Intel Corporation Panther Point USB Enhanced Host Controller #2 (rev 04) 00:1b.0 Audio device: Intel Corporation Panther Point High Definition Audio Controller (rev 04) 00:1c.0 PCI bridge: Intel Corporation Panther Point PCI Express Root Port 1 (rev c4) 00:1c.1 PCI bridge: Intel Corporation Panther Point PCI Express Root Port 2 (rev c4) 00:1d.0 USB controller: Intel Corporation Panther Point USB Enhanced Host Controller #1 (rev 04) 00:1f.0 ISA bridge: Intel Corporation Panther Point LPC Controller (rev 04) 00:1f.2 SATA controller: Intel Corporation Panther Point 6 port SATA Controller [AHCI mode] (rev 04) 00:1f.3 SMBus: Intel Corporation Panther Point SMBus Controller (rev 04) 00:1f.6 Signal processing controller: Intel Corporation Panther Point Thermal Management Controller (rev 04) 02:00.0 Network controller: Intel Corporation Centrino Advanced-N 6235 (rev 24) The driver for the wireless interface is iwlwifi.

  • What's the best way to manage error logging for exceptions?

    - by Peter Boughton
    Introduction If an error occurs on a website or system, it is of course useful to log it, and show the user a polite message with a reference code for the error. And if you have lots of systems, you don't want this information dotted around - it is good to have a single centralised place for it. At the simplest level, all that's needed is an incrementing id and a serialized dump of the error details. (And possibly the "centralised place" being an email inbox.) At the other end of the spectrum is perhaps a fully normalised database that also allows you to press a button and see a graph of errors per day, or identifying what the most common type of error on system X is, whether server A has more database connection errors than server B, and so on. What I'm referring to here is logging code-level errors/exceptions by a remote system - not "human-based" issue tracking, such as done with Jira,Trac,etc. Questions I'm looking for thoughts from developers who have used this type of system, specifically with regards to: What are essential features you couldn't do without? What are good to have features that really save you time? What features might seem a good idea, but aren't actually that useful? For example, I'd say a "show duplicates" function that identifies multiple occurrence of an error (without worrying about 'unimportant' details that might differ) is pretty essential. A button to "create an issue in [Jira/etc] for this error" sounds like a good time-saver. Just to re-iterate, what I'm after is practical experiences from people that have used such systems, preferably backed-up with why a feature is awesome/terrible. (If you're going to theorise anyway, at the very least mark your answer as such.)

  • How to decide on a price for the project as a freelancer

    - by Shekhar_Pro
    I have seen similar question on this SE site but none comes close to a sure shot answer and many are rather subjective. So i am taking a website as an example to be more objective for you to decide its development price i should quote for the complete work.I would like to have specific figures. In past I have developed many projects for my classmates (Computer science and few .net) when i was in college and there i just arbitrarily quoted the price i will take depending on my mood and customer's ability to pay.. usually ranging from Rs.500 (about $10 USD) to Rs. 1500 (about $30 USD). I have also developed few websites but that was open-source and free. But this time impressed by my work i have got a client that wants to get a website developed similar to this: [ http://www.jeetle.in/ ]. So taking this website as an example tell me how much should i charge for complete work from designing to payment gateway implementation (Excluding the charge the payment gateway provider will take). Few information you might like to consider. I am the only developer on this project if that makes any difference. And i would be using ASP.Net and MSSQL Express for server side processing and jQuery on client. Time period for development offered is about 4 to 6 Weeks. Its like i know my work but not how much I'm worth

  • What is an appropriate language for expressing initial stages of algorithm refinement?

    - by hydroparadise
    First, this is not a homework assignment, but you can treat it as such ;). I found the following question in the published paper The Camel Has Two Humps. I was not a CS major going to college (I majored in MIS/Management), but I have a job where I find myself coding quite often. For a non-trivial programming problem, which one of the following is an appropriate language for expressing the initial stages of algorithm refinement? (a) A high-level programming language. (b) English. (c) Byte code. (d) The native machine code for the processor on which the program will run. (e) Structured English (pseudocode). What I do know is that you usually want to start your design implementation by writing down pseuducode and then moving/writing in the desired technology (because we all do that, right?) But I never thought about it in terms of refinement. I mean, if you were the original designer, then you might have access to the original pseudocode. But realisticly, when I have to maintain/refactor/refine somebody elses code, I just keep trucking with the language it currently resides in. Anybody have a definitive answer to this? As a side note, I did a quick scan of the paper as I havn't read every single detail. It presents various score statistics, can't find where the answers are with the paper.

  • Conflict resolution for two-way sync

    - by K.Steff
    How do you manage two-way synchronization between a 'main' database server and many 'secondary' servers, in particular conflict resolution, assuming a connection is not always available? For example, I have an mobile app that uses CoreData as the 'database' on the iOS and I'd like to allow users to edit the contents without Internet connection. In the same time, this information is available on a website the devices will connect to. What do I do if/when the data on the two DB servers is in conflict? (I refer to CoreData as a DB server, though I am aware it is something slightly different.) Are there any general strategies for dealing with this sort of issue? These are the options I can think of: 1. Always use the client-side data as higher-priority 2. Same for server-side 3. Try to resolve conflicts by marking each field's edit timestamp and taking the latest edit Though I'm certain the 3rd option will open room for some devastating data corruption. I'm aware that the CAP theorem concerns this, but I only want eventual consistency, so it doesn't rule it out completely, right? Related question: Best practice patterns for two-way data synchronization. The second answer to this question says it probably can't be done.

  • Failed Project: When to call it?

    - by Dan Ray
    A few months ago my company found itself with its hands around a white-hot emergency of a project, and my entire team of six pulled basically a five week "crunch week". In the 48 hours before go-live, I worked 41 of them, two back to back all-nighters. Deep in the middle of that, I posted what has been my most successful question to date. During all that time there was never any talk of "failure". It was always "get it done, regardless of the pain." Now that the thing is over and we as an organization have had some time to sit back and take stock of what we learned, one question has occurred to me. I can't say I've ever taken part in a project that I'd say had "failed". Plenty that were late or over budget, some disastrously so, but I've always ended up delivering SOMETHING. Yet I hear about "failed IT projects" all the time. I'm wondering about people's experience with that. What were the parameters that defined "failure"? What was the context? In our case, we are a software shop with external clients. Does a project that's internal to a large corporation have more space to "fail"? When do you make that call? What happens when you do? I'm not at all convinced that doing what we did is a smart business move. It wasn't my call (I'm just a code monkey) but I'm wondering if it might have been better to cut our losses, say we're not delivering, and move on. I don't just say that due to the sting of the long hours--the company royally lost its shirt on the project, plus the intangible costs to the company in terms of employee morale and loyalty were large. Factor that against the PR hit of failing to deliver a high profile project like this one was... and I don't know what the right answer is.

  • Optimized algorithm for line-sphere intersection in GLSL

    - by fernacolo
    Well, hello then! I need to find intersection between line and sphere in GLSL. Right now my solution is based on Paul Bourke's page and was ported to GLSL this way: // The line passes through p1 and p2: vec3 p1 = (...); vec3 p2 = (...); // Sphere center is p3, radius is r: vec3 p3 = (...); float r = ...; float x1 = p1.x; float y1 = p1.y; float z1 = p1.z; float x2 = p2.x; float y2 = p2.y; float z2 = p2.z; float x3 = p3.x; float y3 = p3.y; float z3 = p3.z; float dx = x2 - x1; float dy = y2 - y1; float dz = z2 - z1; float a = dx*dx + dy*dy + dz*dz; float b = 2.0 * (dx * (x1 - x3) + dy * (y1 - y3) + dz * (z1 - z3)); float c = x3*x3 + y3*y3 + z3*z3 + x1*x1 + y1*y1 + z1*z1 - 2.0 * (x3*x1 + y3*y1 + z3*z1) - r*r; float test = b*b - 4.0*a*c; if (test >= 0.0) { // Hit (according to Treebeard, "a fine hit"). float u = (-b - sqrt(test)) / (2.0 * a); vec3 hitp = p1 + u * (p2 - p1); // Now use hitp. } It works perfectly! But it seems slow... I'm new at GLSL. You can answer this questions in two ways: Tell me there is no solution, showing some proof or strong evidence. Tell me about GLSL features (vector APIs, primitive operations) that makes the above algorithm faster, showing some example. Thanks a lot!

  • Hobbyist programmer releasing software with a donate button

    - by espais
    I'd like to start this with a disclaimer that I realize that a full, clear-cut answer should be sought out by a lawyer. I am more so curious about what other users of this community have done Say that I had a small program that I had developed for fun, that I wished to release to the public. I'll drop it out there with one of the various open-source licenses, and probably put it up on SourceForge or Git in case if anybody should ever want to fork/maintain/check out code. Also say that I wanted to accept donations for the project, with absolutely 0 expectation that people will send any money. However, if somebody donated in order to buy me a beer or a pizza for the work that they liked, I would accept gladly. The question, then, is what are the general requirements of accepting donations? Can it go into a personal account with no questions asked as a "gift," or do I need to setup an LLC to avoid any taxation issues? (US citizen here). Again, yes this should be lawyer discussed, but I also know that many projects that I see have the ability to donate, and assume that the community probably has a decent amount of experience in this regard.

  • How does using a LGPL gem affect my MIT licensed application?

    - by corsen
    I am developing an open source ruby application under the MIT license. I am using this license because I don't want to place any restrictions on the users of the application. Also I can actually read and understand this license. I recently started using another ruby gem in my project (require "somegem"). This ruby gem is under the LGPL license. Do I have to change anything about my project because I am using this other ruby gem that is licensed with LGPL? My project does not contain the source code for the other gem and it is not shipped with my project. It is simply listed as a dependency so that ruby gems will install it and my project will call into it from my code. Additionally, it would be helpful to know if there are any licenses I need to "watch out for" because using them would affect the license of my project. There are some other post about this topic but phrased in different ways. Since I find this license stuff tricky I am hoping to get a answer directed at my situation. Thank you, Corsen

  • Friday Tips #6, Part 2

    - by Chris Kawalek
    Here is a question about updating Oracle VM: Question: How can I perform Oracle VM 3 server updates from Oracle VM Manager? Answer by Gregory King, Principal Best Practices Consultant, Oracle VM Product Management: Server Update Manager is a built-in feature of the Oracle VM Manager. Basically, Server Update Manager automatically configures YUM updates on all the Oracle VM Servers, pointing each to our Unbreakable Linux Network (ULN) update channel for Oracle VM. The servers periodically check with our Oracle YUM repository and notify the Oracle VM Manager that an update is available for each server. Actual server updates must be triggered by the Oracle VM administrator – they are not executed automatically. At this point, you can use the Oracle VM Manager to put a server into maintenance mode which live migrates all the running Oracle VM Guests to other Oracle VM Servers in the server pool. Once all the Oracle VM Guests have been migrated, the Oracle VM administrator can trigger the update on the server. The entire process is documented in the Installation and Upgrade Guide of Oracle VM Documentation so I won’t spend time detailing the steps. However, configuring the Server Update Manager is exceedingly simple. Simply navigate to the Tools and Resources tab in the Oracle VM Manager, select the link for Server Update Manager and ensure the following values are added to the text boxes as shown in the illustration below: YUM Base URL: http://public-yum.oracle.com/repo/OracleVM/OVM3/latest/x86_64 YUM GPG Key: file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle Every server in the pool will be automatically configured for YUM updates once you choose the Apply button. Many thanks to Greg and Rick for providing the answers to this week's questions. If you want to ask us something, hit up Twitter and use hashtag #AskOracleVirtualization. See you next week! -Chris

  • Speed up ADF Mobile Deployment to Android with Keystore

    - by Shay Shmeltzer
    As you might have noticed from my latest ADF Mobile entries, I'm doing most of my ADF Mobile development on a windows machine and testing on an Android device. Unfortunately the Android/windows experience is not as fast as the iOS/Mac one. However, there is one thing I learned today that can make this a bit less painful in terms of the speed to deploy and test your application - and this is to use the "Release" mode when deploying your application instead of the "Debug" mode. To do this you'll first need to define a keystore, but as Joe from our Mobile team showed me today, this is quite easy. Here are the steps: Open a command line in your JDK bin directory (I just used the JDK that comes with the JDeveloper install). Issue the following command: keytool –genkey –v –keystore <Keystore Name>.keystore –alias <Alias Name> -keyalg RSA –keysize 2048 –validity 10000 Both keystore name and alias names are strings that you decide on. The keytool utility will then prompt you with various questions that you'll need to answer. Once this is done, the next step is to configure your JDeveloper preferences->ADF Mobile to add this keystore there under the release tab:  Then for your application specific deployment profile - switch the build mode from debug to release. The end result is a much smaller mobile application (for example from 60 to 21mb) and a much faster deployment cycle (for me it is about twice as fast as before).

  • Easter eggs as IP protection in software

    - by Simon
    I work in embedded software, and for some reason, management wants to hide an Easter egg as means of IP protection. They call it a watermark, and since our software interact with the video preview feed (the image displayed on a screen before you take a photo), they want me to implement a trigger which will react to some unusual video input (a video konami code like dark - bright - dark - bright - whatever). When this trigger fires, something strange happens (which is outside of the normal behavior of the software). The goal is to check whether our software is included in a device. Does it sound like a good idea? I have many argument against this move: What if the konami code is too sensitive and user triggers it? Does this kind of watermark have any legal value? What if this "feature" is discovered by the client? The performance penalty should be very small, since the soft run on small devices. I am the one developping this trigger. If things go wrong, what is my responsibility? What is your opinion about this method? I can't find a link, but I remember seeing an answer on this site suggesting that putting Easter eggs for protection purpose was a good idea. Has anyone tried it with good results?

  • Running CORN job on Ubuntu server for SugarCRM

    - by Logik
    i am pretty inexperienced in Linux.So be descriptive on your answer. My environment :Local Linux server 12.04 hosting Sugar CRM 6.5.2. There is area in sugar CRM called scheduler. I can configured some predefined jobs here. in my case i am trying to run email reminders (ever min/hour/day/month). For this scheduler to be effective, i read some where i need to setup CRON job. So i did some research & finally put following lines in CRONTAB for the root user, as per instructions given in sugarCRM. cd /var/www/crm; php -f cron.php /dev/null 2&1 Well i am creating contracts in my sugarCRM (AOS module) & i want email reminders to be sent for these contracts to the concern person. Now my sugarCRM email is configured correctly & i can send test emails using it. But the CRON + scheduler not giving any result. I can't receive any emails. Then i tried to read /var/log/syslog & it is showing entry for following line each minute. Oct 27 15:03:01 unicomm CRON[28182]: (root) CMD (cd /var/www/crm; php -f cron.php /dev/null 2&1) I've few questions: 1) what does the CRON job line i've added in crontab mean? cd /var/www/crm; php -f cron.php /dev/null 2&1 is not making any sense to me. 2) How am i suppose to get this thing work? I've searched a lot (including SugarCRM forum), but no luck.

  • Logic / Render phases with a single thread

    - by DevilWithin
    The question I have may generate different opinions from different developers, but I'd still like to have an answer on this. Its all about the updating and rendering steps of the game loop, and their use under multi and single threaded environments. Currently, there is one thread running, which takes care of sequentially executing events , logic and rendering. Sometimes, the logic part may wish to change the game state to something else, and in between do some loading of files. The result is that the game hangs completely while loading, and then proceeds to normal rendering of the new state. To go around this, i could make another thread, do the loading there while the main thread renders a smooth loading animation, and then proceed normally. The real question is about if i don't create another thread. I could refresh the screen from the logic thread, and provide some basic loading screen, which could be not so smoothly updated while the files load. In fact, this approach is not loved by a lot of developers, as it scrambles render code in the logic step, which may cause problems of different sorts.. Hope its clear!

  • What are some general guidelines for setting up an iOS project I will want to personally publish but sell in the future?

    - by RLH
    I have an idea for a personal iOS project that I would like to write and release to the iOS store. I'm the type of developer who enjoys developing and publishing. I want to write quality software and take care of my customers. Assuming that I wrote an application that had reasonable success, there is a fair chance that I would want to sell the ownership rights of the app to another party and I'd use the proceeds to develop my next personal project which, in turn, I'd probably want to sell in the future. With that said, what are some general guidelines for creating, making and publishing an iOS project that I will eventually want to transfer to another company/developer? I know this is a bit of a broad question, but I request that the given advice be a general list of tips, suggestions and pitfalls to avoid. If any particular bullet point on your list needs more explanation, I'll either search for the answer or post a new question specific to that requirement. Thank you! Note Regarding this Question I am posting this question on Programmers.SO because I think that this is an issue of software architecting, seeking advice for setting a new application project and publishing a project to the Apple iOS store-- all within the requirements for questions on this site.

  • Cocos2d v2.0 and OpenGL 2.0/1.0: where to start

    - by mm24
    I started developing my very first game 3 months ago using Cocos2d 2.0 for iPhone. I am now in the stage where I'd like to add some cool effects to the bullets and some special weapons (see my waveforms question here). I got a good answer in the cocos2d-iphone forum (see this one). Unfortunately I am a bit paralized now. I don't know if I will be overdoing by learning OpengGL 2.0 or if I should just stick ot the old 1.0. There is a good intro on various tutorial's written in Steffen Itterheims blog (see this post). I would like to add to my game: a blur effect to the bullets (here is a tutorial for OpenGL 1.0) a waveform (see above) some realistic water ripples (here is a nice sample code) So now, given that I don't want to overdo things but at the same time I want to achieve those effects, from where should I start? Should I discard the OpenGL 1.0 tutorials? OR should I use only OpenGL 1.0 code? How can I avoid confusion? I mean, it seems that the compiler recognizes both, but that there are some conflictual calls in some circumnstances, I am fairly sure this has some explanation, is there some reference to this somewhere?

  • Ubuntu 13.04 alongside Windows 8 - How to partition from Windows

    - by mengelkoch
    I plan to install Ubuntu 13.04 alongside Windows 8, and I'm looking for a CLEAR answer on how to conduct partitioning appropriately. I'm very new to all of this so a thorough explanation with minimal jargon would be great. I have an Acer Aspire M5 x64 with 6G RAM. I think I already figured out how to deal with the fast startup, UEFI and SecureBoot issues (I disabled fast startup and disabled Secure Boot). I am able to boot into Ubuntu from a LiveUSB, and I think I am ready to install Ubuntu. Note - despite some advice found here, I do have to disable SecureBoot to boot 13.04 from my LiveUSB. From what I have read here, it seems that I should (at least at first) create the partitions from WITHIN Windows 8, not from the LiveUSB, to avoid reported problems. I have run compmgmt.msc and I see the existing partitions. I see the following: Disk 0: 400 MB Recovery; 300 MB EFI System; Acer (C:) 444.95 GB (Boot, Page File, Crash Dump, Primary Partition); 20 GB Recovery Disk 1: 3.74 GB Primary Partition; 14.90 GB Primary Partition I gather I need to create a mounting point '/' Partition (??), a swap partition, and a home partition. Please explain what these are, how big they should be, how I create them from Windows Disk Management, and anything else I need to know. Eventually, I plan to fully replace Windows 8 with Ubuntu, but for now I want to run alongside Windows 8 and not screw things up. I don't have any critical files saved on this computer yet. Thanks.

  • running adb via wifi on ubuntu 13.04

    - by Blaze Tama
    First, im new on linux so please bear with me. I have a rooted android phone and i was able to run the adb via wifi network on windows, where i just need to go to the adb's directory and type adb connect. However, i can't just do that in my ubuntu. Everytime i enter adb connect, the terminal always said that i dont have the adb and i must install it. When i check the ADT Bundle (I downloaded the bundled one from here), i can see the adb is there inside the platform-tools folder. I already tried to change the directory to the platform-tools and run the adb connect from there, but its still not working. Do i need to install the adb again via terminal? Or did i miss something? You may be wondering why dont i just download the adb (again) via terminal and do trial and error? The answer is because i dont have a good internet connection, so i want to avoid unnecessary downloads. Thanks for your time :D

  • Thoughts on type aliases/synonyms?

    - by Rei Miyasaka
    I'm going to try my best to frame this question in a way that doesn't result in a language war or list, because I think there could be a good, technical answer to this question. Different languages support type aliases to varying degrees. C# allows type aliases to be declared at the beginning of each code file, and they're valid only throughout that file. Languages like ML/Haskell use type aliases probably as much as they use type definitions. C/C++ are sort of a Wild West, with typedef and #define often being used seemingly interchangeably to alias types. The upsides of type aliasing don't invoke too much dispute: It makes it convenient to define composite types that are described naturally by the language, e.g. type Coordinate = float * float or type String = [Char]. Long names can be shortened: using DSBA = System.Diagnostics.DebuggerStepBoundaryAttribute. In languages like ML or Haskell, where function parameters often don't have names, type aliases provide a semblance of self-documentation. The downside is a bit more iffy: aliases can proliferate, making it difficult to read and understand code or to learn a platform. The Win32 API is a good example, with its DWORD = int and its HINSTANCE = HANDLE = void* and its LPHANDLE = HANDLE FAR* and such. In all of these cases it hardly makes any sense to distinguish between a HANDLE and a void pointer or a DWORD and an integer etc.. Setting aside the philosophical debate of whether a king should give complete freedom to their subjects and let them be responsible for themselves or whether they should have all of their questionable actions intervened, could there be a happy medium that would allow the benefits of type aliasing while mitigating the risk of its abuse? As an example, the issue of long names can be solved by good autocomplete features. Visual Studio 2010 for instance will alllow you to type DSBA in order to refer Intellisense to System.Diagnostics.DebuggerStepBoundaryAttribute. Could there be other features that would provide the other benefits of type aliasing more safely?

  • How can I disable recent documents in Unity?

    - by detly
    How do I disable the tracking and display of recently opened files (and whatever else is remembered) in a default installation of Ubuntu 11.10? (Note that this is not a duplicate of How can I keep recent files from appearing in Unity?, since that question and its answers are concerned with temporary and specific filtering. I want to disable it completely for a single user account.) Okay, to deflect the inevitable and expand on my motivation... While trawling the usual forums and Google results for a solution, it (unsurprisingly) seems that the near-universal use cases for this request are either browsing porn or Warhammer research. And the obvious solution to this is to create another user account to contain all evidence. However, this is not why I'm asking, and I don't say that to get all high and mighty about it, it's because this answer won't help. (Even though I really don't have any interest in Warhammer, and I have no idea how that paint pot and brush ended up in my drawer, no that's not glue on my thumb, etc.) My actual use case is that I use my personal laptop for presentations in different circles of my life. I have a user account set up with all the settings I like for presentations (shortcuts, small launcher, default associations, etc). But I don't want an accidental keystroke (or the find dialog) to display other recent presentations I've given, or the files I used in composing the presentation, or whatever. I also don't want to have to recreate this profile for every single presentation I might give. I just want a nice little isolated, memoryless, clean corner of my notebook for public display.

  • Dynamic model interactions

    - by Richard
    I am just curious as to how in many games (namely games like arkham asylum/city, manhunt, hitman) do they make it so that your character can "grab" a character in front of you and do stuff to them. I know this may sound very confusing but for an example go to youtube and search "hitman executions", and the first video is an example of what i'm asking. Basically I'm wondering how they make your model dynamically interact with whatever other model you come across, so in hitman when you come up behind some one with the fibre wire you strangle the other character or if you have the anesthetic you come up behind some person and put your hand over there mouth while they struggle and slowly go to the floor where you lay them down. I am confused as to whether it was animated to use two models using specific bone/skeletal identifiers, if it is just two completely separate animations that are played at the correct time to make it look like they are actually interacting or something else all together. I am not an animator so i assume most of what i just said is not right but i hope that some one can understand what i mean and provide an answer. PS) I am a programmer and I am in the process of building a hitmanesque game, just because i love that style of game and I want to increase my skills on something fun, so if you do know what i'm talking about have some examples with involving both models and programming (i use c++ and mainly Ogre3D at the moment but i am getting into unity and XNA) i would greatly appreciate it. Thanks.
