  • Microsoft Access as a Weapon of War

    - by Damon
    A while ago (probably a decade ago, actually) I saw a report on a tracking system maintained by a U.S. Army artillery control unit.  This system was capable of maintaining a bearing on various units in the field to help avoid friendly fire.  I consider the U.S. Army to be the most technologically advanced fighting force on Earth, but to my terror I saw something on the title bar of an application displayed on a laptop behind one of the soldiers they were interviewing: Tracking.mdb Oh yes.  Microsoft Office Suite had made it onto the battlefield.  My hope is that it was just running as a front-end for a more proficient database (no offense Access people), or that the soldier was tracking something else like KP duty or fantasy football scores.  But I could also see the corporate equivalent of a pointy-haired boss walking into a cube and asking someone who had piddled with Access to build a database for HR forms.  Except this pointy-haired boss would have been a general, the cube would have been a tank, and the HR forms would have been targets that, if something went amiss, would have been hit by a 500lb artillery round. Hope that solider could write a good query :)

  • ASP.NET: Serializing and deserializing JSON objects

    - by DigiMortal
    ASP.NET offers very easy way to serialize objects to JSON format. Also it is easy to deserialize JSON objects using same library. In this posting I will show you how to serialize and deserialize JSON objects in ASP.NET. All required classes are located in System.Servicemodel.Web assembly. There is namespace called System.Runtime.Serialization.Json for JSON serializer. To serialize object to stream we can use the following code. var serializer = new DataContractJsonSerializer(typeof(MyClass)); serializer.WriteObject(myStream, myObject); To deserialize object from stream we can use the following code. CopyStream() is practically same as my Stream.CopyTo() extension method. var serializer = new DataContractJsonSerializer(typeof(MyClass));   using(var stream = response.GetResponseStream()) using (var ms = new MemoryStream()) {     CopyStream(stream, ms);     results = serializer.ReadObject(ms) as MyClass; } Why I copied data from response stream to memory stream? Point is simple – serializer uses some stream features that are not supported by response stream. Using memory stream we can deserialize object that came from web.

  • Copying photos from camera stalls - how to track down issue?

    - by Hamish Downer
    When I copy files from my camera (connected via USB) to the SSD in my laptop a few files get copied and then the copy stalls. I'm not sure why, any ideas or things to investigate appreciated, or bug reports to go and look at. I have read this answer - the camera (Canon 40D in case that matters) mounts fine using gvfs. I can see the photos in Nautilus, or in the terminal (in /run/user/username/gvfs/... ) and I can copy a few photos, but not many. Using the terminal or Nautilus the process hangs until the camera goes to sleep. Digikam fails to copy any at all, as does Rapid Photo Downloader. Shotwell did manage it in the end, but that is very much a work around for me. I have disabled thumbnail generation by nautilus. Load average stays about 1 while this is happening, while CPU usage is half idle, half wait (and a little user/sys for other programs). None of the programs at the top of the cpu list in top are related to copying photos. There is not much in the logs - from /var/log/syslog Dec 2 16:20:52 mishtop dbus[945]: [system] Activating service name='org.freedesktop.UDisks' (using servicehelper) Dec 2 16:20:52 mishtop dbus[945]: [system] Successfully activated service 'org.freedesktop.UDisks' Dec 2 16:21:24 mishtop kernel: [ 2297.180130] usb 2-2: new high-speed USB device number 4 using ehci_hcd Dec 2 16:21:24 mishtop kernel: [ 2297.314272] usb 2-2: New USB device found, idVendor=04a9, idProduct=3146 Dec 2 16:21:24 mishtop kernel: [ 2297.314278] usb 2-2: New USB device strings: Mfr=1, Product=2, SerialNumber=0 Dec 2 16:21:24 mishtop kernel: [ 2297.314283] usb 2-2: Product: Canon Digital Camera Dec 2 16:21:24 mishtop kernel: [ 2297.314287] usb 2-2: Manufacturer: Canon Inc.

  • Removed Java replaced with newest "Sun Java", disc won't boot, and won't let me re-install grub using boot repair disc

    - by Al Rowe
    Had a minor problem with my Stock market platform. Set-up screen would freeze program. Called their tech support, got their "Linux guy", who advised remove all Java and replace, not with synaptic version, but newest Sun Java. After removing, computer auto rebooted, and went to blue mem-test screen. Showed no errors, but couldn't get back in. Tried two versions of boot repair disc from iso (checked md5sum, showed good.), but fix aborted, giving apt-error detected. Opened a terminal and typed (or copy/paste): sudo chroot "/mnt/boot-sav/sda1" apt-get -f install. My system is Ubuntu 12.04. Had a few very minor issues from install, all fixed. Also added some of my favorite gnome tricks just to make life easier, but none that could have caused this. Added script to add shortcuts to desktop, open terminal in any menu from inside it, access root terminal, etc. System was firewalled and using avast antivirus (o.k., I'm paranoid. Used to do Windows sys-op and security.) But relative newbie to Linux.

  • Radeon HD 6850 VMware 3D Support?

    - by Matt
    I'm a new Ubuntu user (new to all of linux actually). I've installed Ubuntu 11.10 x64 and have been enjoying it, but I wanted to see how it would perform using VMware for small time gaming since I find dual booting too much of a nuisance to even bother using Ubuntu at all (sorry!). I have an Asus EAH6850 DirectCU Radeon HD 6850 graphics card and I've installed the additional ATI/AMD proprietary FGLRX graphics driver, but when I open a Windows XP 32bit machine I installed through VMware, I get this message: "The GPU driver currently installed on this host may cause issues with VMware products. If you notice any issues please disable the 3D support in the affected virtual machines." I still have 3D capabilities in the VM but they are very very choppy even running the DX tests (the spinning cube). I've seen people on youtube and other forums saying that since the new 3D acceleration in VMware 8 gaming is very possible through VMs (and I've seen them running the DX tests with the spinning cube very smoothly). I'm wondering if my graphics card isn't fully supported or if I have installed it wrong. Also when I check system info (on the host Ubuntu machine) it says "Graphics VESA:BARTS" Should my Radeon HD 6850 be showing up there? The rest of my basic system info i5 2500k 8GB 1600MHz memory Guest is running with access to all 4 cores of processor and 3gb memory assigned.

  • JavaScript 3D space ship rotation

    - by user36202
    I am working with a fairly low-level JavaScript 3D API (not Three.js) which uses euler angles for rotation. In most cases, euler angles work quite well for doing things like aligning buildings, operating a hovercraft, or looking around in the first-person. However, in space there is no up or down. I want to control the ship's roll, pitch, and yaw. To do that, some people would use a local coordinate system or a permenant matrix or quaternion or whatever to represent the ship's angle. However, since I am not most people and am using a library that deals exclusively in euler angles, I will be using relative angles to represent how to rotate the ship in space and getting the resulting non-relative euler angles. For you math nerds, that means I need to convert 3 euler angles (with Y being the vertical axis, X representing the pitch, and Z representing a roll which is unaffected by the other angles, left-handed system) into a 3x3 orientation matrix, do something fancy with the matrix, and convert it back into the 3 euler angles. Euler to matrix to euler. Somebody has posted something similar to this on SO (http://stackoverflow.com/questions/1217775/rotating-a-spaceship-model-for-a-space-simulator-game) but he ended up just working with a matrix. This will not do for me. Also, I am using JavaScript, not C++. What I want essentially are the functions do_roll, do_pitch, and do_yaw which only take in and put out euler angles. Many thanks.

  • How do I get Graphics drivers / bluetooth / card reader working on an Acer Aspire V3-571G?

    - by Adam
    A couple of days ago I bought an Acer Aspire V3-571G laptop without a system installed on it. The only thing that was there was Linux Linpus. I created a bootable CD with Ubuntu 12.04 64-bit - I read that my processor was 64 bit and that it might be a good configuration for my gear (I'm not especially fluent with all the computer stuff, still trying to learn) and replaced Linpus with Ubuntu. Everything seemed to work fine, but there're few exceptions to that which came pass my way. My bluetooth doesn't work. It seems to be switched on, but when I check my system settings the button is actually off, and I can't drag it 'perminently' to the 'on' position. Tried a couple of commands I found on the net, none of them helped and there was no word whatsoever in my BIOS settings about enabling bluetooth. My card reader has some serious problems with copying more than one file at a time. I tried to put some music on my phone through a MicroSD card adapter (because my bluetooth doesn't work) and it got stuck every single time I copied an album on it. I'm not sure if all my drivers were properly installed, so I checked in the terminal if it could tell me sth about my graphics. typed: sudo lshw -c display and what i got was: *-display UNCLAIMED description: VGA compatible controller product: NVIDIA Corporation vendor: NVIDIA Corporation physical id: 0 bus info: pci@0000:01:00.0 version: a1 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress vga_controller cap_list configuration: latency=0 resources: memory:b2000000-b2ffffff memory:a0000000-afffffff memory:b0000000-b1ffffff ioport:2000(size=128) *-display description: VGA compatible controller product: Ivy Bridge Graphics Controller vendor: Intel Corporation physical id: 2 bus info: pci@0000:00:02.0 version: 09 width: 64 bits clock: 33MHz capabilities: msi pm vga_controller bus_master cap_list rom configuration: driver=i915 latency=0 resources: irq:44 memory:b3000000-b33fffff memory:c0000000-cfffffff ioport:3000(size=64) As I said I'm no expert and not english-speaking generally, but it doesn't seem to be right.

  • Setting up Cluster Configuration using an existing web server as a Primary Node?

    - by RapidWebs
    Thanks in advance for any help which is issued! I am having a slight issue, and need help with the decision making process when it comes to setting up my Cluster Configuration, consisting on a line of Ubuntu Servers (12.04). We currently have a Primary node, which resides in the US within a Datacenter, but we are going to be using this for all serious bandwidth and resource intensive websites, and through a configuration of Virtualmin + Webmin, will be setup as a sort of pseudo-cluster, using Virtualmins Cluster Modules. Anyways, on to the issue: We also have a business line setup locally, with three servers. here are their specs: Intel P4 2.4 ghz, 1GB Ram, 110 gb sata, Ubuntu 12.04* AMD 1.3 ghz, 512MB Ram, 20 GB IDE P3 Xeon 800mhz (dual physical processors), 1GB Ram, 3 * 25 GB Raid Configuration (one in use for host operating system). The first machine is currently IN USE and is serving virtual hosts off a sub-domain. My question is this: How can I integrate the Secondary node (which will be the Primary node per say, in this smaller configuration...) which is currently in use, into the cluster configuration w/ the other two servers for: Sharing Resources Redundancy (HA?) NFS /w the two Raid Disks without having the FORMAT the secondary node, and start fresh moving all my services in to a DRBD network drive or something similar, and than restoring all active virtualmin's Virtual hosts. the idea is that I want minimal downtime to people currently being served from server2.mywebsite.com, and from what I understand, all services need to be on a NFS so that they can be mounted on demand and accessed from the other machine taking over (i.e. Heartbeat + DRBD Config.) but my issue is that i already have all these services installed to their default directory structure: how can i most easily setup this NFS and HA system, move all my desires services to this new drive, and do it with minimal down time, and without breaking Virtualmin and everything else on my server? even just some pointers, a thread i could read, or a step by step check list or run down of commands i could issue to get started would be great! thanks!

  • Ubuntu won't fit 10" netbook's native display

    - by Daniel
    I recently removed Windows 7 Starter from my netbook, and replaced it with Ubuntu 12.10. The problem is some bits of the system doesn't fit the native display resolution of 1024x600 i.e. the bottom bits of Ubuntu is hidden beneath the screen & the only 2 available resolutions are: the default 1024x768 and 800x600. I've also thought about replacing Ubuntu with Lubuntu or Puppy Linux, as the system does run a bit slow, but I can't, as then I won't be able to access the taskbar and application menu which will be hidden beneath the screen. Only Ubuntu with Unity is currently usable, as I can see the Unity Launcher. My Netbook model is HP Mini 210-1004sa, which comes with Intel Graphics Media Accelerator 3150, and has a display 10.1" Active Matrix Colour TFT 1024 x 600. I was able to define a custom resolution 1024x600 using the Q&A: How set my monitor resolution? but when I set that resolution, the desktop area is lowered, with bits of it hidden beneath the screen; & there's a black space left at the top of the screen. I had to revert to the old setting 1024x768 to push the desktop upwards and remove the black space.

  • Why does Ubuntu 13.10 not detect my Win7 partition?

    - by goutham
    I'm trying to install Ubuntu 13.10 alongside Windows 7 on my DELL INSPIRON 14z 5423 laptop and I'm new to all of this. I'm using the Ubuntu 13.10 64-bit ISO burned onto a CD. The first time I tried to install it, Ubuntu said it did not detect any other OS, which meant I only had 4 options: Erase disk and install Ubuntu (I don't want to do this) Encrypt new Ubuntu. Use LVM. Something else. If I choose the Something else option, it brings me to the partition menu and says that I have 1 disk with free space of (500Gb), but that's not true because I have Windows 7. I restarted the laptop several times and booted the CD again and I got exactly the same as I did previously. How do fix this problem and install Ubuntu alongside Windows 7?

  • Laptop Charger Not Recognised Properly on Samsung NP900X3F

    - by user193732
    Firstly thanks for your time. Secondly, having an issue with my power charger on my Samsung Series 9 NP900X3F. When I boot into Ubuntu with the charger plugged in it recognises it as charging. When I unplug the charger after this it is still says it is charging. If I suspend in Ubuntu then plug/unplug during this suspended state it recognises it, but not during normal running. If I knew a little more I'm sure I could grab logs and find out what the difference between wake on suspend and normal running is, but alas I need help! I also am having issues with my keyboard backlight via the fn keys, but that I care about far less. Thank you very much. Linux mikey-900X3F 3.12.0-031200rc1-generic #201309161735 SMP Mon Sep 16 21:38:21 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux (I upgraded my kernel version to remove heinous horizontal artefacts I was getting) Happy to list more info about my system, ima bit of a noob. I did try searching however I can't find any questions at all about my system or related models with the same issue.

  • One of the partion on a usb harddisk cannot automount

    - by holmescn
    It is a very strange problem. My usb harddisk has four partitions, one is primary, the other three are logical (contained within an extended partition). When I plug in the disk, three of the partitions are mounted automatically except one--the first logical partition in the extended partition. Initially I thought it is the problem of system (at that time I used Mint). But after I change to Ubuntu 12.04, the problem wasn't solved. I don't want to add a rule in fstab, and I want to know what happened. The disk is fine, and the partition can be accessed in Windows and mounted manually. result of dmesg | tail: [100933.557649] usb 2-1.2: new high-speed USB device number 4 using ehci_hcd [100933.651891] scsi8 : usb-storage 2-1.2:1.0 [100934.649047] scsi 8:0:0:0: Direct-Access SAMSUNG PQ: 0 ANSI: 0 [100934.650963] sd 8:0:0:0: Attached scsi generic sg2 type 0 [100934.651342] sd 8:0:0:0: [sdb] 625142448 512-byte logical blocks: (320 GB/298 GiB) [100934.651977] sd 8:0:0:0: [sdb] Write Protect is off [100934.651989] sd 8:0:0:0: [sdb] Mode Sense: 03 00 00 00 [100934.652836] sd 8:0:0:0: [sdb] No Caching mode page present [100934.652848] sd 8:0:0:0: [sdb] Assuming drive cache: write through [100934.655354] sd 8:0:0:0: [sdb] No Caching mode page present [100934.655367] sd 8:0:0:0: [sdb] Assuming drive cache: write through [100934.734652] sdb: sdb1 sdb3 < sdb5 sdb6 sdb7 > [100934.737706] sd 8:0:0:0: [sdb] No Caching mode page present [100934.737725] sd 8:0:0:0: [sdb] Assuming drive cache: write through [100934.737731] sd 8:0:0:0: [sdb] Attached SCSI disk result of parted -l: Model: SAMSUNG (scsi) Disk /dev/sdb: 320GB Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 1 32.3kB 21.5GB 21.5GB primary ntfs 3 21.5GB 320GB 299GB extended lba 5 21.5GB 129GB 107GB logical ntfs 6 129GB 236GB 107GB logical ntfs 7 236GB 320GB 83.8GB logical ntfs

  • 12.04 GPU lockup

    - by soandos
    I was able to install Ubuntu 12.04 using the alternative version of the image, (64 bit) but when I start the system it tells me the GPU locked up, and instead presents a text only screen. I understand that this site is not for bug reports, but at the same time, I know that there are some versions of the installer than have to be compatible with my graphics card (Nvidia GTS 360M). I assumed that the mere fact that the alternative installer ran was an indication that I could get some sort of graphical interface running after the install. Is there some way of getting some type of graphical interface running on my machine? Even better would be is there a way to get the rest of the system running as normal (i.e. GPU up and running)? If an internet connection is required to download driver support or something similar, directions for how to configure a wireless connection with WPA2-Personal protection from the text-only interface (bash). Any help would be appreciated. Note: I was able to find this which tells me that the card is supported. Note 2: In the install software stage of the install, I was unable to install anything (no internet connection) Update: The exact error message is [8.591394] [drm] 0000:01:00.0: GPU Lockup - switching to software fbcon Update 2: If I try to install with the regular version of Ubuntu, the screen goes staticy. This also happens if I install with Wubi (distasteful I know) and then try to use Ubuntu. Update 3: I've tried xforcevesa, nomodeset and xforcevesa nomodeset as my wubi boot options. Update 4: Thanks to jokerdino, I can now connect to the internet, so internet tools would now be a possibility.

  • How to Set Up a MongoDB NoSQL Cluster Using Oracle Solaris Zones

    - by Orgad Kimchi
    This article starts with a brief overview of MongoDB and follows with an example of setting up a MongoDB three nodes cluster using Oracle Solaris Zones. The following are benefits of using Oracle Solaris for a MongoDB cluster: • You can add new MongoDB hosts to the cluster in minutes instead of hours using the zone cloning feature. Using Oracle Solaris Zones, you can easily scale out your MongoDB cluster. • In case there is a user error or software error, the Service Management Facility ensures the high availability of each cluster member and ensures that MongoDB replication failover will occur only as a last resort. • You can discover performance issues in minutes versus days by using DTrace, which provides increased operating system observability. DTrace provides a holistic performance overview of the operating system and allows deep performance analysis through cooperation with the built-in MongoDB tools. • ZFS built-in compression provides optimized disk I/O utilization for better I/O performance. In the example presented in this article, all the MongoDB cluster building blocks will be installed using the Oracle Solaris Zones, Service Management Facility, ZFS, and network virtualization technologies. Figure 1 shows the architecture:

I already tried logging out and killing x with service lightdm stop, but still, it freezes as soon as I echo DIS > switch. typing blindly, echo IGD > switch returns me to my console where it reads [ 179.555171] i915: switched off, but it seems the discrete card never gets switched on... running echo DDIS > switch gives me the following: [540....] [drm:atop_op_jump] *ERROR* atombios stuck in loop for more than 5secs aborting [540....] [drm:atom_execute_table_locked] *ERROR* atombios stuck executing CEE2 (len 62, WS 0, PS 0) @ 0xCEFE [540....] [drm:atom_execute_table_locked] *ERROR* atombios stuck executing BBF6 (len 1036, WS 4, PS 0) @ 0xBCF3 [540....] [drm:atom_execute_table_locked] *ERROR* atombios stuck executing BB8C (len 76, WS 0, PS 0) @ 0xBB94 [541....] [drm:r600_RING_TEST] *ERROR* radeon: ring test failed (scratch(0x8504)=0xFFFFFFFF) [541....] [drm:evergreen_resume] *ERROR* evergreen startup failed on resume after that, the atombios part repeats a few times. also, the terminal locks up again and sysrq+REISUB is my only rescue. Has anybody an idea how I can switch to my discrete card without the system locking up? #uname -srvmpio Linux 3.2.0-24-generic #39-Ubuntu SMP Mon May 21 16:52:17 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux #lsb_release -r Description: Ubuntu 12.04 LTS

  • How to set up an inter-OS partition?

    - by Confuzzled Persun
    I need a working partition configuration for use and accessibility on both Ubuntu and Windows. I have an 8GB USB flash drive onto which I am installing Ubuntu 11.10 so that I can have a personal bootable OS wherever I go. I've installed Ubuntu several times, but I just can't seem to get this one partition right. This is my own configuration: Partition 1: Primary - 200MB - Beginning - Ext4 - /boot Partition 2: Primary - 1300MB - End - swap area Partition 3: Logical - 5200MB - Beginning - Ext4 - / Partition 4: Logical - 1258MB - Beginning - Ext4 - /home Partition 5: Logical - 42MB - End - FAT32? - /windows? What I want to do is to get partition 5 configured so I can access it on both the installed Ubuntu system and a Windows system (when the USB drive is connected while Windows is booted). Basically, what I want is Ubuntu installed on the USB drive along with a partition that I can access with other operating systems. I'm thinking I just need the technical configuration of "Use as:" and "Mount point:" for my final partition. But I don't know. Any help with this is appreciated. And any other tips are appreciated as well.

  • Recovering data from /

    - by Abhijit Gavas
    I accidentally installed Ubuntu to one of my data drives from Windows. The drive was a NTFS drive and contained about 80 GB of important data. The size of the drive is 110 GB. Its new file system is ext4. In an attempt to recover the data, I downloaded foremost and tried the following commands: foremost -i / -o /media/281C8DB01C8D7998/Recovery/ -T -v foremost -i /dev/sda7 -o /media/281C8DB01C8D7998/Recovery/ -T -v (sda7 is the drive in question.) It appears that with either command, foremost gets stuck reading some file. Here is the console output: abhi@abi-PC:/dev$ foremost -i /dev/sda7 -o /media/281C8DB01C8D7998/Recovery/ -T -v Foremost version 1.5.7 by Jesse Kornblum, Kris Kendall, and Nick Mikus Audit File Foremost started at Fri Sep 28 20:58:00 2012 Invocation: foremost -i /dev/sda7 -o /media/281C8DB01C8D7998/Recovery/ -T -v Output directory: /media/281C8DB01C8D7998/Recovery_Fri_Sep_28_20_58_00_2012 Configuration file: /etc/foremost.conf Processing: stdin |------------------------------------------------------------------ File: stdin Start: Fri Sep 28 20:58:00 2012 Length: Unknown Num Name (bs=512) Size File Offset Comment Killed As you can see I have to kill it from system monitor. This approach does not seem to be working. What else could I try to recover the files? Please help. The files are very important and I will be devastated if I cannot recover them.

  • Apache DVB http video Streaming bandwidth or priority problem

    - by igino manfre'
    I'm streaming few precompressed DVB videos from cloud. The streams are generated from VLC on "impossible" ports (such as 64085, 64086 etc) reverse proxed by Apache on port 80 and 8080. All the generated streams are listed in "http://95.110.164.61/indexv.html". From an ADSL connection with enough downlink bandwidth, recalling the stream generated by VLC (such as "http://95.110.164.61:64087/mpg2_6.4") it flows fluently. Recalling the same stream proxed by Apache ("http://95.110.164.61/mpg2_6.4") the stream stops and goes. The only situation in which the Apache proxed streams flow regularly is from a site connected through 64 Mbps warranted bandwith with RTT to the server less than 10 mseconds. Please note that streams below 2 Mbps are fluently proxed. The system is a single core xeon with windows 2008 R2 on 4 GB of RAM with 1 Gbps of network bandwidth. The drain of computational and bandwidth resources is negligeable, the RAM usage always lower than 50%. On the system I run many VLC streamers. Any of them drains a variable amount of RAM (from about 25 to 70 MB). On the contrary the couple of httpd.exe processes drain no more than 7 MB. Using Wireshark (on the server) I see that VLC directy send to the client much more packets than Apache, and the stream is framgmented on many frames. I'm not a programmer, a newby of Apache. Can anyone please address me to a specific portion of the Apache's huge documentation? Thank you. igino

  • libgdx actors and instant actions

    - by vaati
    I'm having trouble with actors and actions. I have a list of actors, they all have either no action, or 1 sequence action This sequence action has either : a couple of actions (some are instant, some have duration 0) a couple of actions followed by a parallel action. My problem is the following: some of the instant actions are used to set the position and the alpha of the actor. So when one of the action is "move to x,y and set alpha to 0" the actor is visible for one frame at position 0,0 , move instantly to x,y for the next frame, and then disappears. Though this behaviours is to be expected, I want to avoid it. How can I achieve that? I tried to intercept the actions before I put actors in the stage but I need the stage width/height for some actions. So something like : Action actionSequence = actor.getActions().get(0); Array<Action> actions = ((SequenceAction) actionSequence).getActions(); for(Action act : actions){ if(act.act(0)) System.out.println("action " + act.toString() + " successfully run"); else System.out.println("action " + act.toString() + " wasn't instant"); } won't work. It gets even more complicated when an actor can also have a repeat action in stead of the sequence action (because you have to only run the actions that have duration 0 once without repeat, and then start the repeat). Any help is appreciated.

  • Expanding existing DVCS Wiki

    - by A Lion
    A portion of my job is to maintain technical documentation for a rapidly expanding manufacturing company. Because it is only a portion of my job and the company's product line is expanding so quickly, I can't stay on top of the documentation. As a result, I've been yearning for an information management system with a handful of specific features. I've found many products that have a subset, but none that have all the features I'm looking for. I'm at the point of picking an existing product and expanding it to cover my desired feature set, however, this will be a pet project and I will be learning the underlying language as I go. So, the main question is which existing product will be the easiest to expand to cover the full feature set and has a relatively easy to learn language? Alternatively, have I missed another existing program that will cover the feature set or should be in my list of "close, but not quite there"? Feature Set web interface based on a distributed version control system (e.g., git) easy to edit by logged in novices (e.g. wiki, multimarkdown) outputs in more traditional formats (e.g., doc, odt, pdf) edits held in queue until editor/engineer/manager approves them (e.g., MS Word editing) [this is the really big elephant in list - suggestions on where to start appreciated] edits held in queue specifically for engineer approval [extra limb of the elephant in the list] well-supported in the open source community Closest, but not quite there ikiwiki - http://ikiwiki.info (php) lots of awesome functionality and extensions, including easy to edit and based on DVCS lacks a review/forward for review queue appears to be well-supported within the OSS community gitit - http://gitit.net/ (haskell) easy to edit and based on DVCS lots of outputs in traditional formats a great web-based gui diff interface lacks a review/forward for review queue appears to be primarily maintained by one individual

  • SOA Starting Point: Methods for Service Identification and Definition

    As more and more companies start to incorporate a Service Oriented Architectural design approach into their existing enterprise systems, it creates the need for a standardized integration technology. One common technology used by companies is an Enterprise Service Bus (ESB). An ESB, as defined by Progress Software, connects and mediates all communications and interactions between services. In essence an ESB is a form of middleware that allows services to communicate with one another regardless of framework, environment, or location. With the emergence of ESB, a new emphasis is now being placed on approaches that can be used to determine what Web services should be built. In addition, what order should these services be built? In May 2011, SOA Magazine published an article that identified 10 common methods for identifying and defining services. SOA’s Ten Common Methods for Service Identification and Definition: Business Process Decomposition Business Functions Business Entity Objects Ownership and Responsibility Goal-Driven Component-Based Existing Supply (Bottom-Up) Front-Office Application Usage Analysis Infrastructure Non-Functional Requirements  Each of these methods provides various pros and cons in regards to their use within the design process. I personally feel that during a design process, multiple methodologies should be used in order to accurately define a design for a system or enterprise system. Personally, I like to create a custom cocktail derived from combining these methodologies in order to ensure that my design fits with the project’s and business’s needs while still following development standards and guidelines. Of these ten methods, I am particularly fond of Business Process Decomposition, Business Functions, Goal-Driven, Component-Based, and routinely use them in my designs.  Works Cited Hubbers, J.-W., Ligthart, A., & Terlouw , L.
