  • A simple example of movement prediction

    - by Daniel
    I've seen lots of examples of theory about the reason for client-side prediction, but I'm having a hard time converting it into code. I was wondering if someone knows of some specific examples that share some of the code, or can share their knowledge to shed some light into my situation. I'm trying to run some tests to get a the movement going (smoothly) between multiple clients. I'm using mouse input to initiate movement. I'm using AS3 and C# on a local Player.IO server. Right now I'm trying to get the Client side working, as I'm only forwarding position info with the client. I have 2 timers, one is an onEnterFrame and the other is a 100ms Timer, and one on mouseClick listener. When I click anywhere with a mouse, I update my player class to give it a destination point On every enterFrame Event for the player, it moves towards the destination point At every 100ms it sends a message to the server with the position of where it should be in a 100ms. The distance traveled is calculated by taking the distance (in Pixels) that the player can travel in one second, and dividing it by the framerate for the onEnterFrame handler, and by the update frequency (1/0.100s) for the server update. For the other Players, the location is interpolated and animated on every frame based on the new location. Is this the right way of doing it?

  • AD account locks out when using Outlook 2007?

    - by Down Town
    Hi, I/we have a problem with our Windows Server 2008 forest and Exchange. We are buying Exchange hosting from another firm and Exchange Server is in their Windows Server 2008 forest. So, we have two forests and there isn't any trusts between these two forests. Our own forest logon name is [email protected] and we also use the same email address to logon to the Exchange mailbox. Everything works fine if both our AD account and Exchange mailbox account have the same password, but if the passwords don't match, our AD account gets locked out. I have tried to figure out why Outlook sends false logon attemps to our AD. If someone can help, please do.

  • How can I use fetchmail (or another email grabber) with OSX keychain for authentication?

    - by bias
    Every fetchmail tutorial I've read says putting your email account password clear-text in a config file is safe. However, I prefer security through layers (since, if my terminal is up and someone suspecting such email foolery slides over and simply types "grep -i pass ~/.*" then, oops, all my base are belong to them!). Now, with msmtp (as opposed to sendmail) I can authenticate using the OSX keychain. Is there an email 'grabber' that lets me use Keychains (specifically the OSX keychain) or at least, that lets me MD5 the password? This is a duplicate of my unanswered question on serverfault. I've put it on superuser because I'm doing this on a personal computer (viz. with OSX) so it's more of a superuser question.

  • How to sell logistical procedures that require less time to perform but more finesse?

    - by foampile
    I am working with a group where part of the responsibilities is managing a certain set of configuration files which, of course, have the same skeleton/structure across different environments but different values (like server, user, this setting, that setting etc.). Pretty classic scenario... The problem is that everyone just goes and modifies final, environment-specific files and basically repeats the work for every environment. Personally, I am offended to have to peform repeatable, mundane tasks in this day and age when we have technologies to automate it all. So I devised a very simple procedure of abstracting the files into templates, stubbing env-specific values with parameters and then wrote a simple Perl script that, given a template and an environment matrix with env-specific values for each param, produces the final file. So this is nothing special, cutting-edge or revolutionary -- I am pretty sure that 20 years ago efficient places did their CM like that. However, that requires that changes are made at the template level and then distributed across different environments using the script and not making changes in the final environment-specific files. This is where I am encountering resentment as they feel "comfortable" doing it their old, manual, repeated labor way. Personally, I don't have a problem with them working hard rather than smart but the problem is when I have to build on top of someone else's changes, I have to merge their changes into my template from a specific file, which takes time and is grueling. So my question is how to go about selling my method, which makes it so much faster in an environment that is resentful to change and where most things have to be done at the level of the least competent team member?

  • USB AutoRun Dialog: Open a webpage option not shown in dialog

    - by Jake M
    I am attempting to make our webpage open when someone plugs in our USB device. My Problem: When we plug in the USB device the autorun dialog appears but there is never an option to open/run the webpage we have specified. See below pic of the dialog we see. Isn't there meant to be an option that says something like "Open in Internet Explorer" or etc.? What we are hoping to achieve is to have another option below 'Use this drive for backup' that says something like 'Open in Web Browser' or something that will ultimately open our webpage when the users decides to. Heres our code that is inside the file autorun.inf which is placed on the USB device: [autorun] shellexecute=http://exds-test.epicservices.com.au/V10InstallationInfo.aspx action=Open Website label=EXDS USB Drive

  • Ubuntu Linux: Process swap memory and memory usage

    - by David Halter
    My Ubuntu eats more memory than the task manager is showing: sudo ps -e --format rss | awk 'BEGIN{c=0} {c+=$1} END{print c/1024}' 1043.84 free -m total used free shared buffers cached Mem: 3860 1878 1982 0 20 679 -/+ buffers/cache: 1178 2681 Swap: 2729 1035 1693 That's strange. Can someone explain this difference? But what is more important: I'd like to know how much memory a process is really using. I don't want to know the virtual memory size, but rather the resident memory plus swap of a process. I have also tried to output the format param "sz" of 'ps', but the sum of this is to high (5450 MB) (param 'size' gives 8323.45 MB). Are there any other options? I really want to use this, to determine which programs/processes are eating to much memory (and swap), to kill them, because hibernate might not be working if the swap partition is to little.

  • Excel VBA Function runtime error 1004: Application-defined or object-defined error

    - by music2myear
    I'm trying to learn functions for the purpose of simplifying and reusing code whenever necessary. I began by turning something I use pretty often into a function: Returning the integer value of the last non-blank row in a spreadsheet. Function FindLastDataLine(strColName As String) As Long FindLastDataLine = Range(strColName).Offset(Rows.Count - 1, 0).End(xlUp).Row End Function Sub PracticeMacro() intItemCount = FindLastDataLine("A:A") MsgBox ("There are " & intItemCount & " rows of data in column A.") End Sub When I run this I recieve the runtime error '1004' "Application-defined or object-defined error" which Help helpfully defines as "someone else's fault" to quote not quite verbatim. Where might I be going wrong?

  • Can't install Linux drivers for ASUS N-13 wireless adapter

    - by jcc
    I have a USB N13 wireless Adapter with install CD-- For Windows. I downloaded drivers from ASUS FOR N13 for Linux. Disregard install CD that came with adapter; it's for Windows. I then downloaded Windows Wireless driver install program app from Software Center in Ubuntu 12.10. The problem is me. I am newbie with all things linux; software sources, G Debi, default archive manager, synaptic package manager and the Terminal. The downloaded driver file is a .zip file. I managed to extract it to a tar.gz file and then to open it to the contained files. When I use the Windows Wireless driver program it ends up telling me there is no .inf file and goes no further. It wants to install .inf file but I don't even see one in all the files. Can someone please help me . I think you can tell by my wording I don't have a clue. I hope this is'nt too chatty. I've tried to be explicit and to the point. Thank you. Oh, this is on an ASUS LAPTOP K53E. I've looked all over Ask Ubuntu and finally found some questions even on the N13 but they didn't help; still some differences in the exact problem.

  • What is wrong with my logic for the divide and conquer algorithm for Closest pair problem?

    - by Programming Noob
    I have been following Coursera's course on Algorithms and came up with a thought about the divide/conquer algorithm for the closest pair problem, that I want clarified. As per Prof Roughgarden's algorithm (which you can see here if you're interested): For a given set of points P, of which we have two copies - sorted in X and Y direction - Px and Py, the algorithm can be given as closestPair(Px,Py): Divide points into left half - Q, and right half - R, and form sorted copies of both halves along x and y directions - Qx,Qy,Rx,Ry Let closestPair(Qx,Qy) be points p1 and q1 Let closestPair(Rx,Ry) be p2,q2 Let delta be minimum of dist(p1,q1) and dist(p2,q2) This is the unfortunate case, let p3,q3 be the closestSplitPair(Px,Py,delta) Return the best result Now, the clarification that I want is related to step 5. I should say this beforehand, that what I'm suggesting, is barely any improvement at all, but if you're still interested, read ahead. Prof R says that since the points are already sorted in X and Y directions, to find the best pair in step 5, we need to iterate over points in the strip of width 2*delta, starting from bottom to up, and in the inner loop we need only 7 comparisions. Can this be bettered to just one? How I think is possible seemed a little difficult to explain in plain text, so I drew a diagram and wrote it on paper and uploaded it here: Since no one else came up with is, I'm pretty sure there's some error in my line of thought. But I have literally been thinking about this for HOURS now, and I just HAD to post this. It's all that is in my head. Can someone point out where I'm going wrong?

  • Embedded Tomcat Cluster

    - by ThreaT
    Can someone please explain with an example how an Embedded Tomcat Cluster works. Would a load balancer be necessary? Since we're using embedded tomcat, how would two separate jar files (each a standalone web application with their own embedded tomcat instance) know where eachother are and let eachother know their status, etc? Here is the code I have so far which is just a regular embedded tomcat without any clustering: import javax.servlet.ServletException; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import java.io.File; import java.io.IOException; import java.io.Writer; public class Main { public static void main(String[] args) throws LifecycleException, InterruptedException, ServletException { Tomcat tomcat = new Tomcat(); tomcat.setPort(8080); Context ctx = tomcat.addContext("/", new File(".").getAbsolutePath()); Tomcat.addServlet(ctx, "hello", new HttpServlet() { protected void service(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException { Writer w = resp.getWriter(); w.write("Hello, World!"); w.flush(); } }); ctx.addServletMapping("/*", "hello"); tomcat.start(); tomcat.getServer().await(); } } Source: java dzone

  • Creating a custom NAS compatible with the Mac Time machine and for media streaming

    - by Bobby Alexander
    I am planning to assemble a custom NAS machine using an Intel Atom processor. I need the NAS for the following purposes: It should be accessible from by Windows PC so that I can dump data on the NAS (installations, media etc) It should be accessible from my Macbook for the above use. I should be able to use it with the Mac time machine software for backup. The media should be available to my PS3 for streaming. I should be able to access it from my iphone. All the above features should be available over wireless. The time machine feature is very important. Is this even possible? Can someone provide resources on how I can assemble such a machine and setup the required software on it? Much appreciated.

  • How to solve this problem with a 'tuned' prompt in ZSH?

    - by Mnementh
    I have an adjusted prompt in my ZSH-configuration. Main feature is, that this prompt is colored red, so that I can easily it distinguish from the outputs of programs. My prompt is defined as follows: PROMPT=$'\e[0;31m%n@%m:%~> \e[0m' This works mostly fine, but sometimes my cursor switches to another position on tab-completion and some characters are left behind on the screen and mangle up the commandline. That is a little annoyance, but if someone knows a solution for this, I would appreciate it.

  • Exporting a VM running as a Domain Controller

    - by AndyM
    There is a Microsoft KB article that talks about best practices for running a DC on a VM. One of the notes is "Do not use the Export feature on a virtual machine that is running a domain controller". In order to export a VM, the VM needs to be turned off. If you turn off a DC VM, export it, import it on another server and then power the VM back on, there should be no risk as long as the original (exported) VM is never powered back on. Can someone explain to me why this isn't supported? After doing some searching on Google, the sites I found just regurgitated this line from the KB article, but didn't offer any explanation as to why this isn't supported.

  • configure open_basedir under Plesk

    - by cori
    This might be a question for ServerFault, and if it wasn't for the Plesk aspect I would ask it there to start with, so if it's better suited for over there let me know and I'll move it. I'm working on a dedicated server set up as a reseller account with Plesk to manage the domains and server configuration, and I need to add a directory to the local open_basedir configuration for a specific vhost. Given Plesk's normal methodology, I expected to be able to go to /var/www/vhost/{%DOMAINNAME%}/conf and modify vhost.conf and place a new value there, as I have successfully done with other configuration settings for this domain (turning safe_mode off, for instance). When I do so, however, the new setting doesn't take (per phpinfo();). If I edit httpd.conf (which the plesk configuration specifically says not to do in the notes at the top of httpd.conf) the setting takes. Is there something specific about the open_basdir setting that makes it not configurable in vhost.conf? How much trouble am I letting myself in for by editing the vhost-specific httpd.conf (I imagine is someone makes changes in the plesk web interface it might be overwritten, but what other risk is there)? Thanks!

  • How do I circumvent Spotify's updater for my regular users in Windows?

    - by cros
    I run a Windows Vista machine where I have Spotify installed. My account is the only account with administrator rights on the machine, which means only I can update Spotify. This means that any other user on the machine won't be able to run Spotify if there is an update that I haven't installed. Is there any way to circumvent this? EDIT: I tried setting up a task in the Task Scheduler to start spotify.exe with administrative rights any time someone logged in, which I hoped would allow an update, but it didn't, so I'm open to new suggestions.

  • Session Evaluations

    - by BuckWoody
    I do a lot of public speaking. I write, teach, present and communicate at many levels. I love to do those things. And I love to get better at them. And one of the ways you get better at something is to get feedback on how you did. That being said, I have to confess that I really despise the “evaluations” I get at most venues. From college to technical events to other locations, at Microsoft and points in between, I find these things to be just shy of damaging, and most certainly useless. And it’s not always your fault. Ouch. That seems harsh. But let me ask you one question – and be as honest as you can with the answer – think about it first: “What is the point of a session evaluation?” I’m not saying there isn’t one. In fact, I think there’s a really important reason for them. In my mind, it’s really this: To make the speaker / next session better. Now, if you look at that, you can see right away that most session evals don’t accomplish this goal – not even a little. No, the way that they are worded and the way you (and I) fill them out, it’s more like the implied goal is this: Tell us how you liked this speaker / session. The current ones are for you, not for the speaker or the next person. It’s a popularity contest. Don’t get me wrong. I want to you have a good time. I want you to learn. I want (desperately, oh, please oh please) for you to like me. But in fact, that’s probably not why you went to the session / took the class / read that post. No, you want to learn, and to learn for a particular reason. Remember, I’m talking about college classes, sessions and other class environments here, not a general public event. Most – OK, all – session evaluations make you answer the second goal, not the first. Let’s see how: First, they don’t ask you why you’re there. They don’t ask you if you’re even qualified to evaluate the session or speaker. They don’t ask you how to make it better or keep it great. They use odd numeric scales that are meaningless. For instance, can someone really tell me the difference between a 100-level session and a 200-level one? Between a 400-level and a 500? Is it “internals” (whatever that means) or detail, or length or code, or what? I once heard a great description: A 100-level session makes me say, “wow - I’m smart.” A 500-level session makes me say “wow – that presenter is smart.” And just what is the difference between a 6 and a 7 answer on this question: How well did the speaker know the material? 1  2  3  4  5  6  7  8  9  10 Oh. My. Gosh. How does that make the next session better, or the speaker? And what criteria did you use to answer? And is a “10” better than a “1” (not always clear, and various cultures answer this differently). When it’s all said and done, a speaker basically finds out one thing from the current session evals: “They liked me. They really really liked me.” Or, “Wow. I think I may need to schedule some counseling for the depression I’m about to go into.” You may not think that’s what the speaker hears, but trust me, they do. Those are the only two reactions to the current feedback sheets they get. Either they keep doing what they are doing, or they get their feelings hurt. They just can’t use the information provided to do better. Sorry, but there it is. Keep in mind I do want your feedback. I want to get better. I want you to get your money and time’s worth, probably as much as any speaker alive. But I want those evaluations to be accurate, specific and actionable. I want to know if you had a good time, sure, but I also want to know if I did the right things, and if not, if I can do something different or better. And so, for your consideration, here is the evaluation form I would LOVE for you to use. Feel free to copy it and mail it to me any time. I’m going to put some questions here, and then I’ll even include why they are there. Notice that the form asks you a subjective question right away, and then makes you explain why. That’s work on your part. Notice also that it separates the room and the coffee and the lights and the LiveMeeting from the presenter. So many presenters are faced with circumstances beyond their control, and yet are rated high or low personally on those things. This form helps tease those apart. It’s not numeric. Numbers are easier for the scoring committees but are useless for you and me. So I don’t have any numbers. We’re actually going to have to read these things, not put them in a machine. Hey, if you put in the work to write stuff down, the least we could do is take the time to read it. It’s not anonymous. If you’ve got something to say, say it, and own up to it. People are not “more honest” when they are anonymous, they are less honest. So put your name on it. In fact – this is radical – I posit that these evaluations should be publicly available. Forever. Just like replies to a blog post. Hey, if I’m an organizer, I would LOVE to be able to have access to specific, actionable information on the attendees and the speakers. So if you want mine to be public, go for it. I’ll take the good and the bad. Enjoy. ------------------------------------------------------------------------------------------------------------------------------------------- Session Evaluation – Date, Time, Location, Topic Thanks for giving us your time today. We know that’s valuable, and we hope you learned something you can use from the session. If you can answer these questions as completely as you can, it will help the next person who attends a session here. Your Name: What you do for a living: (We Need your background to evaluate your evaluation) How long you have been doing that: (Again, we need your background to evaluate your evaluation) Paste Session Description Here: (This is what I said I would talk about) Did you like the session?                     No        Meh        Yes (General subjective question – overall “feeling”. You’ll tell us why in a minute.)  Tell us about the venue. Temperature, lights, coffee, or the online sound, performance, anything other than the speaker and the material. (Helps the logistics to be better or as good for the next person) 1. What did you expect to learn in this session? (How did you interpret that extract – did you have expectations that I should work towards for the next person?) 2. Did you learn what you expected to learn? Why? Be very specific. (This is the most important question there is. It tells us how to make the session better for someone like you.) 3. If you were giving this presentation, would you have done anything differently? What? (Helps us to gauge you, the listener, and might give us a great idea on how to do something better. Thanks!) 4. What will you do with the information you got? (Every presenter wants you to learn, and learn something useful. This will help us do that as well or better)

  • How do I compare two Excel documents?

    - by arathorn
    The compare function in Word 2007 is very handy -- is there a similar capability in Excel 2007? I can't seem to find it... The documents I'm trying to compare are essentially two versions of the same content. Unfortunately, "Track Changes" has not been used. If file comparison not a built-in feature, what alternatives are out there for doing this? UPDATE [2009-08-05]: I ran across this (somewhat dated) overview of some of the third-party options that are available: http://www.comparesuite.com/solutions/compare_utilities_review/compare-files-excel.htm UPDATE [2009-08-12]: I ended up going with the Beyond Compare answer, but several of the other answers below were adequate as well, and might be more useful for someone else. (E.g., if you don't own a license for BeyondCompare, or want a comparison GUI that's integrated into Excel.) See also: How do I diff two spreadsheets on Stack Overflow

  • What's the shortest way to post a cropped screenshot on the web?

    - by Borek
    If I want to send someone a piece of my screen this is what I currently do: PrtScr or Alt+PrtScr Open Paint.NET Paste the screen shot Make a selection Crop image to selection Save image to some location - and remember it! Go to some image hosting site (there are plenty of them in the days of Twitter) Click their "Browse" button Browse for the image if I happened to remember the location where I stored it :) Upload the image and obtain the link which I can share This is simply too many steps. I don't usually mind doing steps 1 to 5 but especially steps 6 and 9 are annoying. Jing is pretty close to what I'm looking for but I find their horrible URLs unbearable. If there was something with similar functionality but better or pluggable hosting, that would be great.

  • Spherical to Cartesian Coordinates

    - by user1258455
    Well I'm reading the Frank's Luna DirectX10 book and, while I'm trying to understand the first demo, I found something that's not very clear at least for me. In the updateScene method, when I press A, S, W or D, the angles mTheta and mPhi change, but after that, there are three lines of code that I don't understand exactly what they do: // Convert Spherical to Cartesian coordinates: mPhi measured from +y // and mTheta measured counterclockwise from -z. float x = 5.0f*sinf(mPhi)*sinf(mTheta); float z = -5.0f*sinf(mPhi)*cosf(mTheta); float y = 5.0f*cosf(mPhi); I mean, this explains that they do, it says that it converts the spherical coordinates to cartesian coordinates, but, mathematically, why? why the x value is calculated by the product of the sins of both angles? And the z by the product of the sine and cosine? and why the y just uses the cosine? After that, those values (x, y and z) are used to build the view matrix. The book doesn't explain (mathematically) why those values are calculated like that (and I didn't find anything to help me to understand it at the first Part of the book: "Mathematical prerequisites"), so it would be good if someone could explain me what exactly happen in those code lines or just give me a link that helps me to understand the math part. Thanks in advance!

  • Suggestions? Password & Encrypted Read/Write File like a Mac (.dmg or .SparseBundle) also R/W on Windows, Ubuntu

    - by Jeff Drew
    For years I have used .dmg or .sparsebundle (Encrypted and Password Protected) to safely keep home directory backups on my Mac. Now, I am looking for a similar Full Permissions/Read/Write that maintains an encrypted, and password protected file that it Tri-Platform. I'd like to have the future ability to use it on Mac OS X, Windows 7/8, and Ubuntu (current releases+). I appreciate your recommendations. Thank you. (I like mounting a DMG and having a file directory structure that can be easily maintained and organized. When done, un-mounting the file.) (I've seen Windows tools to open encrypted DMG files? and I will explore these options, but with the desire to also keep the file accessible on on three OSes, someone might have additional suggestions.)

  • how to create java zip archives with a max file size limit [closed]

    - by Marci Casvan
    I need to write an algorithm in java (for an android app) to read a folder containing more folders and each of those containing images and audio files so the structure is this: mainDir/subfolders/myFile1.jpg It must be in java, something like perl script is not an option. It would preferably be for the compressed archive in order to squeeze as many files as possible before mailing the zip. Just a normal zip (no jar). My problem is that I need to limit the size of the archive to 16mb and at runtime, create as many archives as needed to contain all my files from my main mainDir folder. I tried several examples from the net, I read the java documentation, but I can't manage to understand and put it all together the way I need it. Has someone done this before or has a link or an example for me? I resolved the reading of the files with a recursive method but I can't write the logic for the zip creation I'm open for suggestions or better, a working example. EDIT: FileNotFoundException (no such file or directory) this was my initial post at Stack Overflow. I've got an answer to it, but I can't set the size of the ZipEntry and the logic doesn't work and also when extracting the my files from the zip I get the compression method not supported error.

  • Uninstalled Ubuntu, no GRLDR?

    So I'm a big fat idiot. I installed Ubuntu 11.04 on my school's laptop, and here's come the time that I have to turn it back in. I wrote GRUB to the Master Boot Record, thinking it wasn't going to be permanent. So, fast forward to yesterday. I decided to hell with this, and popped in my Windows 7 CD, deleted the whole partition, formatted to NTFS, and installed Windows 7 on it. I'm surfing the web and my computer overheats [totally typical] I boot up, and get this: Try (hd0,0): FAT32: No GRLDR Try (hd0,1): invalid or null Try (hd0,2): invalid or null Try (hd0,3): invalid or null Try (hd1,0): NTFS5: No grldr Try (hd1,1): invalid or null Try (hd1,2): invalid or null Try (hd1,3): invalid or null Cannot find GRLDR.

  • VMware - Watching multiple virtual machine screens

    Hi, I don't know even if I put the question right, but here's what I'd like to accomplish. I have avoided specifying exact Vmware virtualization product here because I'm not sure which one would be most suitable for the task at hand. I am developing an application that works in local network. This application has to run on several computers at the same time, and it's important to me, as a developer and tester, to see (literally) how it behaves at all times on all computers. Is there any way to connect to screens of virtual machines deployed on ESX, ESXi, Sever 2.0, or some other product, so that I can see something like grid of screens, say 4x4 or 6x4 or whatever number of scaled screens, at the same time? Ability to interact with screens directly from grid (by double-clicking a screen, for instance, and then getting full resolution screen) would be greatly appreciated, of course. I hope that someone understood what I meant here. :)

  • Can not understand this script

    - by Jim
    Can someone help me understand this script? It is from sysconf_add and I am new to scripting. I need to do something similar. function add_word() { local word=$1 local word_quoted=$2 if ! word_present; then $debug && cp $file $tmpf sed -i -e "${lineno} { s/^[[:space:]]*\($var=\".*\)\(\".*\)/\1 $word_quoted\2/; s/=\" /=\"/ }" $file $debug && diff -u $tmpf $file else echo \"$word\" already present fi # some balancing for vim"s syntax highlighting }
