  • BizTalk 2009 - Size Functoid Fun

    - by StuartBrierley
    Recently when mapping a flat file from a third party source, I needed to check whether some elements had been sent with any content or not. In the source message these elements were being supplied in the form: <comment /> I though I would try using the size functoid, assuming that it would return a size of 0 for these empty elements.  What actully happens is that the Size funtoid returned a size of 1 rather than the 0 I was expecting. To get what I considered to be the correct output I needed to add a String Right Trim functoid before the Size functoid.  This then returned the "required" size of 0.

  • FFmpeg multi pass encoding

    - by Levan
    Sorry, I am really new to this, and have problems doing some tasks without help. So I have a terminal command: ffmpeg \ -y \ -i '/media/levan/BEEA60D8EA608E89/Downloads/Videos/Tony Braxton - Un-Break My Heart.VOB' \ -s 1920x1080 \ -aspect 16:9 \ -r 25 \ -b 15550k \ -bt 19792k \ -vcodec libtheora \ -acodec libvorbis \ -ac 2 \ -ar 48000 \ -ab 320k \ ddd.ogg and I want to have 3 pass video in output video, but how do I accomplish this? I found that I must write -pass n command some where, but where to write it I do not know. I tested this and wrote -pass 3 at the end but then the terminal just showed a > symbol.

  • I can't get a native resolution of 1920x1080 on 11.10 (AOC f22 on a Nvidia Geforce GTS 450)

    - by Mikeeeee
    I have a problem were the highest resolution I can get is 1360x769, this is a 22 inch LCD monitor with a native resolution of 1920x1080_60 I have tried numerous drivers but nothing changed I tried editing the xorg.conf scipt with no success (I am a noob with linux though). Running many commands in terminal witch I got from people with similar problems only gives me errors like "Failed to get size of gamma for output default. I get edid checksum is invalid error on boot down also. I think there maybe a communication problem between my screens EDID and ubuntu although xp and windows 7 detect my screen without any errors and automatically set native resolution. also when I am installing ubuntu I get a horrible screen flashing every few seconds until I have installed the nvidia driver. pc specks if it helps x64 os, mainboard N68PV-GS, 4 gig ram, AMD Phenom(tm) 9350e Quad-Core Processor × 4, Nvidia Geforce gts450 512mb, hard drives set up in a onboard nvidia raid array striped. realy need to get a better resolution, 1360x769 does not look nice on a 22 inch screen. ty

  • How can I use smbclient to connect to Windows shares by hostname when a firewall is enabled?

    - by skyblue
    I can't connect to file shares on Windows computers using smbclient -L //hostname when the firewall is enabled. This occurs whether I'm using ufw (which allows outgoing traffic and replies back in with the default configuration) or iptables (where I'm allowing outgoing traffic and replies back in with iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT). However, smbclient -L //ip-address works whether the firewall is enabled or not. I also tested this against a Samba server running on Ubuntu and again smbclient -L //hostname does not work when the firewall is enabled, but smbclient -L //ip-address works whether the firewall is enabled or not. For reference, here are the iptables rules I used during testing: *filter :INPUT DROP [0:0] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [0:0] -A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT -A INPUT -p icmp -j ACCEPT -A INPUT -d 224.0.0.251/32 -p udp -m udp --dport 5353 -j ACCEPT COMMIT

  • How to xkill an application by its id?

    - by Hanynowsky
    I need to simulate the behavior of the keyboard shortcut (ALT+F4) using Terminal for a given application. If I open for example gedit and click ALT + F4 , then GEDIT will be xkilled. If I want to achieve same thing using Terminal, how should I proceed? The command export PIDTOKILL=pidof gedit | grep [^*]; xkill -id $PIDTOKILL does not work and gives the following error: xkill: killing creator of resource 0x3f38 X Error of failed request: BadValue (integer parameter out of range for operation) Major opcode of failed request: 113 (X_KillClient) Value in failed request: 0x3f38 Serial number of failed request: 8 Current serial number in output stream: 9 I think I am confusing application id and process id here

  • Where does ntpdate get its settings from and what is the "no servers can be used" error about?

    - by wilhil
    When I run ntpdate on its own, I get the following output: 8 Jun 15:47:46 ntpdate[31251]: no servers can be used, exiting If I run it with the -q ntp.ubuntu.com switch, it seems to query just fine. I have been hunting through many files and the most relevant one I have found is /etc/default/ntpdate, however, even with NTPDATE_USE_CONF set to no, I just can't understand/see how this error is occurring Any ideas? Update-- been looking non stop... It appears that ntupdate-debianworks fine and is the actual command that makes use of /etc/default/ntupdate, but, this doesn't answer the main question and I still can't find it...

  • Resize hard drive partition to make more space for /var

    - by user3357381
    I am running out of space in the /var partition. I have plenty of space in my /home partition. How do I shrink the /home partition to make more space for the /var partition? I have read some blogs that say to use the GParted Live CD. As a new user, I'm not quite sure if this is the ideal route. What is the best way to create more space for /var ?

  • Bumblebee optirun appears to depend on Intel

    - by user206398
    I have a Lenovo T420 with Intel and Nvidia graphics. On upgrade to Ubuntu Saucy, I had to purge and reinstall bumblebee-nvidia to get beyond optirun failing to find a GPU driver. Now, "optirun glxgears" and "optirun sol" succeed, but optirun fails on 2 Virtual Life viewers that it supported in the past, Cool VL (CoolVLViewer-1.26.8.34-Linux-x86) and Imprudence (Imprudence 1.4.0 beta2). In both cases, the error output is huge, but it starts with libGL error: failed to load driver: i965 and libGL error: failed to load driver: swrast From the little I can discover, i965 is an Intel graphics driver, which should not be invoked at all. I haven't found any information about swrast. I suspect that some of the X configuration associated with Bumblebee has some Intel dependence that is invoked on certain library calls, but not others. I haven't discovered any definite information on this line. The Cool VL Viewer runs without optirun, but complains about the insufficiency of the Intel graphics.

  • Cocos2d: carom like game

    - by Raj
    Now I am working on carrom like game using cocos2d+Box2d. I set world gravity(0,0), want gravity in z - axis. I set following value for coin striker body: Coin body: density = 20.0f; friction = 0.4f; restitution = 0.6f; Shape Circle with radius - 15/PTM_RATIO Striker body: density = 25.0f; friction = 0.6f; restitution = 0.3f; Shape Circle with radius - 15/PTM_RATIO Output is not smooth, when I apply ApplyLinearImpulse(force,position); Coin movement looks like floating in air....takes too much time to stop... Which value of coin and striker makes it look like real carom?

  • Thread count in Java game

    - by Taylor Hill
    I'm just curious as to what a reasonable number of threads is for a simple 2D mmo in Java. Is it reasonable to have two threads per connection, one for the input stream and one for the output stream? The reason I ask is because I use a blocking method on the input stream, and a workaround seems unnecessarily complex if I were to try to get around it without adding threads. This is mostly for my own edification; I don't expect to have 5 million people playing it ever, or even 5, but I'm wondering what a good scalable solution is, and if this is reasonable for a small server (<30 connections).

  • Optical Character Recognition software recommendations?

    - by Tim
    I have seen some ebooks/papers that were apparently scanned from their paper versions but the text in the ebooks/papers can amazingly be copied out. I suppose the directly-scanned versions must have been processed by some Optical Character Recognition software. So I would like to know what are the recommended Optical Character Recognition softwares? Especially those that are either for Ubuntu or free? If those for Windows are far more superior, please let me know as well. I am particularly interested in those OCRs that can accept a scanned pdf file as input and still produce as output another pdf file that looks the same as the input one but with its text copyable. Thanks and regards! Please limit one software per answer

  • Non-mathematical Project Euler (or similar)?

    - by Juha Untinen
    I checked the post (Where can I find programming puzzles and challenges?) where there's a lot of programming challenges and such, but after checking several of them, they all seem to be about algorithms and mathematics. Is there a similar site for purely logic/functionality-based challenges? For example: - Retrieve data using a web service - Generate output X from a CSV file - Protect this code against SQL injection - Make this code more secure - What is wrong with this code (where the error is in logic, not syntax) - Make this loop more efficient Does a challenge site like that exist? Especially one that provides hints and/or correct solutions. That would be a very helpful learning site.

  • Check validity Partition in python

    - by fadhil
    I have a question, I really don't understand about partition of set. There are 3 definition that we have to know, and I don't know how to implement the definition into python language. In my case, I have a set of RegionsCode which is set(['Sub-Saharan Africa', 'East Asia & Pacific\n', 'Region\n', 'Middle East & North Africa\n', 'North America\n', 'Latin America & Caribbean\n', 'South Asia\n', 'Sub-Saharan Africa\n', 'Europe & Central Asia\n']) And the question is: Determine if RegionCodes is a valid partition of ?????????????????????? n ??????????????????. There are three steps to showing that a partition is valid, all three steps need to be included here. Output the result of each step to the terminal. I would really appreciate if there is someone helps me.. thank you

  • Looking for a dynamic programming solution

    - by krammer
    Given a sequence of integers in range 1 to n. Each number can appear at most once. Let there be a symbol X in the sequence which means remove the minimum element from the list. There can be an arbitrarily number of X in the sequence. Example: 1,3,4,X,5,2,X The output is 1,2. We need to find the best way to perform this operation. The solution I have been thinking is: Scan the sequence from left to right and count number of X which takes O(n) time. Perform partial sorting and find the k smallest elements (k = number of X) which takes O(n+klogk) time using median of medians. Is there a better way to solve this problem using dynamic programming or any other way ?

  • BCM4313 Wireless on Ubuntu Server 12.04

    - by KJ Tsanaktsidis
    I'm trying to run an old netbook with Broadcom BCM4313 wireless as a print server with Ubuntu Server 12.04. Setting up the wireless without the GUI, however, is proving problematic. I do think however I've narrowed down the problem. I've tried both the wl driver (from bcmwl-kernel-source) as well as the (included) brcmsmac driver. With both of them, when I issue the command iwlist wlan0 scanning (eth1 for wl), I only see neighbouring networks- not my own. I believe this might be because my networks are n-only, but my neighbouring networks are mixed mode (I suspect this because the output of iwlist wlan0 scanning shows "Bit Rates" only as high as 54 Mb/s). Any ideas how to go about getting this thing to connect?

So i did the following: sudo add-apt-repository ppa:ubuntu-audio-dev sudo apt-get update sudo apt-get dist-upgrade And still couldn't get the sound . Then i found the temp fix for this issue. The temp fix is to Suspend the machine completely and resume. However after restart the same thing happens. Is there a solution to this issue?

  • Using VBA to model data in Autodesk Inventor?

    - by user108478
    I have a close friend who is using a specific device that records the dimensions of an object as it is eroded and outputs the dimensional data to an excel sheet. The object is spherical in nature but is eroded from the top and bottom, so the shape is constantly changing and a single formula for surface area and volume would not work. This is where Inventor comes in. My friend can plug the dimensional data to Inventor and it immediately returns the surface area and volume. The erosion process takes several minutes to complete and records data at very short intervals, so it would be very arduous to plug in the data thousand of time. Since Inventor supports macros and VBA, is there a way to plug the data into Inventor and output it into another spreadsheet? Any suggestions would be appreciated.

  • Determining the angle to fire a shot when target and shooter moves, and bullet moves with shooter velocity added in

    - by Azaral
    I saw this question: Predicting enemy position in order to have an object lead its target and followed the link in the answer to stack overflow. In the stack overflow page I used the 2nd answer, the one that is a large mathematical derivation. My situation is a little different though. My first question though is will the answer provided in the stack overflow page even work to begin with, assuming the original circumstances of moving target and stationary shooter. My situation is a little different than that situation. My target moves, the shooter moves, and the bullets from the shooter start off with the velocities in x and y added to the bullets' x and y velocities. If you are sliding to the right, the bullets will remain in front of you as you move so as long as your velocity remains constant. What I'm trying to do is to get the enemy to be able to determine where they need to shoot in order to hit the player. Unless the player and enemy is stationary, the velocity from the ship adding to the velocity of the bullets will cause a miss. I'd rather like to prevent that. I used the formula in the stack overflow answer and did what I thought were the appropriate adjustments. I've been banging at this for the last four hours and I just can't make it click. It is probably something really simple and boneheaded that I am missing (that seems to be a lot of my problems lately). Here is the solution presented from the stack overflow answer: It boils down to solving a quadratic equation of the form: a * sqr(x) + b * x + c == 0 Note that by sqr I mean square, as opposed to square root. Use the following values: a := sqr(target.velocityX) + sqr(target.velocityY) - sqr(projectile_speed) b := 2 * (target.velocityX * (target.startX - cannon.X) + target.velocityY * (target.startY - cannon.Y)) c := sqr(target.startX - cannon.X) + sqr(target.startY - cannon.Y) Now we can look at the discriminant to determine if we have a possible solution. disc := sqr(b) - 4 * a * c If the discriminant is less than 0, forget about hitting your target -- your projectile can never get there in time. Otherwise, look at two candidate solutions: t1 := (-b + sqrt(disc)) / (2 * a) t2 := (-b - sqrt(disc)) / (2 * a) Note that if disc == 0 then t1 and t2 are equal. If there are no other considerations such as intervening obstacles, simply choose the smaller positive value. (Negative t values would require firing backward in time to use!) Substitute the chosen t value back into the target's position equations to get the coordinates of the leading point you should be aiming at: aim.X := t * target.velocityX + target.startX aim.Y := t * target.velocityY + target.startY Here is my code, after being corrected by Sam Hocevar (thank you again for your help!). It still doesn't work. For some reason it never enters the section of code inside the if(disc = 0) (obviously because it is always less than zero but...). However, if I plug the numbers from my game log on the enemy and player positions and velocities it outputs a valid firing solution. I have looked at the code side by side a couple of times now and I can't find any differences. There has got to be something simple I'm missing here. If someone else could look at this code and determine what is going on here I'd appreciate it. I know it's not going through that section because if it were, shouldShoot would become true and the enemy would be blasting away at the player. This section calls the function in question, CalculateShootHeading() if(shouldMove) { UseEngines(); } x += xVelocity; y += yVelocity; CalculateShootHeading(); if(shouldShoot) { ShootWeapons(); } UpdateWeapons(); This is CalculateShootHeading(). This is inside the enemy class so x and y are the enemy's x and y and the same with velocity. One output from my game log gives Player X = 2108, Player Y = -180.956, Player X velocity = 10.9949, Player Y Velocity = -6.26017, Enemy X = 1988.31, Enemy Y = -339.051, Enemy X velocity = 1.81666, Enemy Y velocity = -9.67762, 0 enemy projectiles. The output from the console tester is Bullet position = 2210.49, -239.313 and Player Position = 2210.49, -239.313. This doesn't make any sense. The only thing that could be different is the code or the input into my function in the game and I've checked that and I don't think that it is wrong as it's updated before this and never changed. float const bulletSpeed = 30.f; float const dx = playerX - x; float const dy = playerY - y; float const vx = playerXVelocity - xVelocity; float const vy = playerYVelocity - yVelocity; float const a = vx * vx + vy * vy - bulletSpeed * bulletSpeed; float const b = 2.f * (vx * dx + vy * dy); float const c = dx * dx + dy * dy; float const disc = b * b - 4.f * a * c; shouldShoot = false; if (disc >= 0.f) { float t0 = (-b - std::sqrt(disc)) / (2.f * a); float t1 = (-b + std::sqrt(disc)) / (2.f * a); if (t0 < 0.f || (t1 < t0 && t1 >= 0.f)) { t0 = t1; } if (t0 >= 0.f) { float shootx = vx + dx / t0; float shooty = vy + dy / t0; heading = std::atan2(shooty, shootx) * RAD2DEGREE; } shouldShoot = true; }
