  • How should I isolate computers with different roles on a network

    - by fishhead
    I work in an industrial plant and we have one network(physical wire) that us used for both office usage and for process systems. The office computers are only used for typical office needs but occasionally do connect to the process computers to obtain information from a sql server or for some other purpose. A new initiative is in the works and is rolling down hill from corporate and that is to standardize how the the computers are used at work and they would be severely locked down and only a standard set of applications will be allowed to execute. one of the requirements is to also have non office computers isolated from the company domain. our non-office computers are a mix of Man-Machine interfaces and sql-servers all running software that non standard. My question is, how can we divorce the control systems computers from the company domain but still have access to the servers from the company domain. thanks

  • EloTouch touchscreen suspends correctly but does not come out of standby on Ubuntu 10.04

    - by Ton van den Heuvel
    I am using an EloTouch touchscreen on a minimal Ubuntu 10.04 installation. I have a bare Xserver running without any desktop environment, just an xterm. The touchscreen is working great, but there is still one small problem. As soon as the touchscreen goes to standby, it is not coming out of standby when touching the screen. Using a keyboard or mouse does get it out of standby though. I am looking for any hints or directions to a cause of this problem. Is this an x.org configuration problem? A driver problem? Is this a known problem with touchscreens in general? Any pointers are welcome. The driver I am using is an unreleased EloTouch driver (3.5.0). I received it through a reseller who can not give me any technical information unfortunately.

    - by Teddy
    I have a server that runs JBoss. When I type bad URL to that server it gives me version like this: JBossWeb/2.0.1.GA - what version of JBoss that would be? A SSL certificate will be bought and provided for me so that I could install it in JBoss. I would really appreciate any HOWTO or any information how to install ready SSL certificate on JBoss. Do I need to generate any files with openssl, when this SSL certificate will be bought from some other company that sells SSL certificates? Thanks in advance for any help.

  • Modern techniques for spriting

    - by DevilWithin
    Hello, I would like to know the flow for making modern 2D game artwork. How are the assets made nowadays? Bitmap? Vector-based? Hand-drawn and painted? Drawn digitally? Modeled in 3D and exported to bitmaps? I would like some information on programs as well, for fine looking art. Why does Flash's vector art style look good in most games? How do I make equivalent graphics with external tools? Or equaly good and not vector-based, anyway. Any special hints for animating? An answer oriented towards a one-man-army indie developer with little experience but some artistic sense would be appreciated! Not a complete dummy with paint programs, but also not a master at all, just need efficient ways to achieve results. Thanks. NOTE: Pixel art is not the goal of this question, nothing related to direct pixel manipulation should be brought up here, but you're free to do exactly that :)

  • How do i find out what's preventing delete requests from working in iis7.5 and iis8?

    - by Simon
    Our site has an MVC Rest API. Recently, both the live servers and my development machine stopped accepting DELETE requests, instead returning a 501 Not Implemented response. On my development machine, which is Windows 7 running IIS7.5, the solution was to add these lines to our Web.config, under system.webServer / handlers: <remove name="ExtensionlessUrlHandler-Integrated-4.0" /> ... <add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE" type="System.Web.Handlers.TransferRequestHandler" resourceType="Unspecified" requireAccess="Script" preCondition="integratedMode,runtimeVersionv4.0" /> However, this didn't work on any of our live servers; not on Sever 2008 + IIS7.5 and not on Server 2012 + IIS8. There are no verbs set up in Request Filtering, and WebDAV is not installed on any of our live servers. The error page gives no further information, and nothing gets recorded in the logs. How do I find out what's preventing DELETE requests from working in iis7.5 and iis8?

  • SQL SERVER – Load Generator – Free Tool From CodePlex

    - by pinaldave
    One of the most common questions I receive is if there any tool available to generate load on SQL Server. Absolutely there is a fabulous free tool available to generate load on SQL Server on Codeplex. This tool was released in 2008 but it is still extremely relevant to generate the load on SQL Server as well works fabulously. CodePlex is a project initiated by Microsoft for hosting open source softwares. The best part of this SQL Server Load Generator is that users can run multiple simultaneous queries again SQL Server using different login account and different application name. The interface of the tool is extremely easy to use and very intuitive as well. One of the things which I felt needed improvement was a default configuration. As every single time when I was adding a query the default settings were showing up and I had to manually change that. However, when I went to Menu >> Tools >>Options I was really happy as it has options to change every single default which is available. Here one can give default username, password, database name as well various settings related to configuration. Additionally application logging is also possible through the options. A couple of other important points I noticed was the button to reset counters as well status bar containing useful information of Total Threads, Completed Queries and Failed Queries. I use this frequently for my load testing. What tool do you use for SQL Server Load Generator?

  • What is user/owner 24561?

    - by ralphthemagician
    So, I just installed the node.js package from nodejs.org and I was poking around to see what it installed. Over in /usr/local/bin I saw this owner 24561. I see it in a few other places too. What is this? What does it mean? Should it be root like everything else? lrwxr-xr-x 1 root wheel 66 Jun 23 13:02 mate -> /Applications/TextMate.app/Contents/SharedSupport/Support/bin/mate -rwxr-xr-x 1 24561 wheel 18865984 Jun 29 09:32 node -rwxr-xr-x 1 24561 wheel 355 Jun 29 09:32 node-waf lrwxr-xr-x 1 root wheel 38 Jul 3 12:15 npm -> ../lib/node_modules/npm/bin/npm-cli.js What was curious is that I couldn't find any other information about this user by Googling. Using OS X Lion 10.7.4 with Xcode installed if that makes any difference.

  • #altnetseattle &ndash; MEF, What is it?

    - by GeekAgilistMercenary
    I dived into the MEF session with Glenn Block, Sourabh Mathur, Brian Henderson, and others.  Glenn covered the basic architectural ideas of MEF and then dived into a few examples. Is a framework around decoupling components. Built around the idea of discoverable type systems. Traditional extensibility mechanisms have a host and the respective extensions, commonly linking these two aspects with a form of registration. MEF removes the need for the registration part of the architecture and uses a contract. At some point with MEF you get down to parts, which removes even the complexity of a host or extensions, but a truly evolvable architecture based on natural growth of parts. Also referred to as the framework that removes the "new" keyword. The idea is that parts pull together other parts that they need.  Between each part is a contract. Each part has imports or exports for the parts it needs or the things it offers. If one checks out the MEF Codeplex Site you will find a host of additional information.  The framework download also has some decent examples that help one get kick started.

  • Working with data and meta data that are separated on different servers

    - by afuzzyllama
    While developing a product, I've come across a situation where my group wants to store meta data for data entry forms (questions, layout, etc) in a different database then the database where the collected data is stored. This is mostly for security because we want to be able to have our meta data public facing, while keeping collected data as secure as possible. I was thinking about writing a web service that provides the meta information that the data collection program could access. The only issue I see with this approach is the front end is going to have to match the meta data with the collected data, which would be more efficient as a join on the back end. Currently, this system is slated to run on .NET and MSSQL. I haven't played around with .NET libraries running in SQL, but I'm considering trying to create logic that would pull from the web service, convert the meta data into a table that SQL can join on, and return the combined data and meta data that way. Is this solution the wrong way to approach the problem? Is there a pattern or "industry standard" way of bringing together two datasets that don't live in the same database?

  • Can't boot into Ubuntu from CD, or from Acronis True Image recovery disk

    - by ChrisA
    I can boot my computer off a home-burned-from-ISO-image Windows 7 (x64 or x86) installation CD, without problems. It's a Quad 6600, 4GB RAM, 8800GT and most of the time runs Win7 with no problems. However, if I boot off a CD containing Ubuntu (10.04 or 9.something IIRC), or a recovery disk created with Acronis True Image Home 2010, it: boots starts to load the OS from the CD then hangs ... and I have to reset. I've tried all these CDs on another computer, and they boot up into Ubuntu or Acronis respectively with no problems at all. Any ideas what to look for? Sorry this is a little vague but I have no idea where to start, really ... if there's more information needed I'll edit the question. TIA!

  • Netbook performs hard shutdown without warning on low battery power

    - by Steve Kroon
    My Asus EEE netbook performs a hard shutdown when it reaches low battery power, without giving any warning - i.e. the power just goes off, without any shutdown process. I can't find anything in the syslog, and no error messages are printed before it happens. I've had this problem on previous (K)Ubuntu versions, and hoped updating to Ubuntu Precise would help resolve the issue, but it hasn't. The option in the Power application for "when power is critically low" is currently blank - the only options are a (grayed-out) hibernate and "Power off". I have re-installed indicator-power to no effect. The time remaining reported by acpi is unstable, as is the time remaining reported by gnome-power-statistics. (For example, running acpi twice in succession, I got 2h16min, and then 3h21min remaining. These sorts of jumps in the remaining time are also in the gnome-power-statistics graphs.) It might be possible to write a script to give me advance warning (as per @RanRag's comment below), but I would prefer to isolate why I don't get a critical battery notification from the system before this happens, so that I can take action as appropriate (suspend/shutdown/plug in power) when I get a notification. Some additional information on the battery: kroon@minia:~$ upower -i /org/freedesktop/UPower/devices/battery_BAT0 native-path: /sys/devices/LNXSYSTM:00/device:00/PNP0A08:00/PNP0C0A:00/power_supply/BAT0 vendor: ASUS model: 1005P power supply: yes updated: Fri Aug 17 07:31:23 2012 (9 seconds ago) has history: yes has statistics: yes battery present: yes rechargeable: yes state: charging energy: 33.966 Wh energy-empty: 0 Wh energy-full: 34.9272 Wh energy-full-design: 47.52 Wh energy-rate: 3.7692 W voltage: 12.61 V time to full: 15.3 minutes percentage: 97.248% capacity: 73.5% technology: lithium-ion History (charge): 1345181483 97.248 charging 1345181453 97.155 charging 1345181423 97.062 charging 1345181393 96.970 charging History (rate): 1345181483 3.769 charging 1345181453 3.899 charging 1345181423 4.061 charging 1345181393 4.201 charging kroon@minia:~$ cat /proc/acpi/battery/BAT0/state present: yes capacity state: ok charging state: charging present rate: 332 mA remaining capacity: 3149 mAh present voltage: 12612 mV kroon@minia:~$ cat /proc/acpi/battery/BAT0/info present: yes design capacity: 4400 mAh last full capacity: 3209 mAh battery technology: rechargeable design voltage: 10800 mV design capacity warning: 10 mAh design capacity low: 5 mAh cycle count: 0 capacity granularity 1: 44 mAh capacity granularity 2: 44 mAh model number: 1005P serial number: battery type: LION OEM info: ASUS

  • Design Pattern Advice for Bluetooth App for Android

    - by Aimee Jones
    I’m looking for some advice on which patterns would apply to some of my work. I’m planning on doing a project as part of my college work and I need a bit of help. My main project is to make a basic Android bluetooth tracking system where the fixed locations of bluetooth dongles are mapped onto a map of a building. So my android app will regularly scan for nearby dongles and triangulate its location based on signal strength. The dongles location would be saved to a database along with their mac addresses to differentiate between them. The android phones location will then be sent to a server. This information will be used to show the phone’s location on a map of the building, or map of a route taken, on a website. My side project is to choose a suitable design pattern that could be implemented in this main project. I’m still a bit new to design patterns and am finding it hard to get my head around ones that may be suitable. I’ve heard maybe some that are aimed at web applications for the server side of things may be appropriate. My research so far is leading me to the following: Navigation Strategy Pattern Observer Pattern Command Pattern News Design Pattern Any advice would be a great help! Thanks

  • XNA C# Platformer - physics engine or tile based?

    - by Hugh
    I would like to get some opinions on whether i should develop my game using a physics engine (farseer physics seems to be the best option) or follow the traditional tile-based method. Quick background: - its a college project, my first game, but have 4 years academic programming experience - Just want a basic platformer with a few levels, nothing fancy - want a shooting mechanic, run and gun, just like contra or metal slug for example - possibly some simple puzzles I have made a basic prototype with farseer, the level is hardcoded with collisions and not really tiled, more like big full-screen sized tiles, with collision bodies drawn manually along the ground and walls etc. My main problem is i want a simple retro feel to the jumping and physics but because its a physics simulation engine its going to be realistic, whereas typical in air controllable physics for platformers arent realistic. I have to make a box with wheel body fixture under it to have this effect and its glitchy and doesnt feel right. I chose to use a physics engine because i tried the tile method initially and found it very hard to understand, the engine took care of alot things to save me time, mainly being able to do slopes easily was nice and the freedom to draw collision bounds wherever i liked, rather then restricted to a grid, which gave me more freedom for art design also. In conclusion i don't know which method to pick, i want to use a method which will be the most straight forward way to implement and wont give me a headache later on, preferably a method which has an abundance of tutorials and resources so i dont get "stuck" doing something which has been done a million times before! Let me know i haven't provided enough information for you to help me! Thanks in advance, Hugh.

  • Wireless not working on desktop with Asus USB-N13 (B1) wireless adapter

    - by user900749
    I am trying to connect my desktop to a wireless network. I have purchased an ASUS USB-N13 B1 adapter. I have followed instructions for installing drivers and disabling conflicting drivers. I have thoroughly searched and could not find a solution. The adapter is recognized and powered on. I have entered the ssid and password information into the wireless network configuration. Other machines can connect to this wireless network, and the machine can connect online via ethernet without issue. Here is the output of some commands which summarize my configuration, and might give some clues : ~$ cat /etc/lsb-release DISTRIB_ID=Ubuntu DISTRIB_RELEASE=12.04 DISTRIB_CODENAME=precise DISTRIB_DESCRIPTION="Ubuntu 12.04.1 LTS" ~$ uname -a Linux petra 3.2.0-29-generic #46-Ubuntu SMP Fri Jul 27 17:03:23 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux ~$ lsusb Bus 001 Device 006: ID 0b05:17ab ASUSTek Computer, Inc. ~$ dmesg [ 1883.823150] wlan0: authenticate with 48:5b:39:e7:25:5e (try 1) [ 1884.020027] wlan0: authenticate with 48:5b:39:e7:25:5e (try 2) [ 1884.220025] wlan0: authenticate with 48:5b:39:e7:25:5e (try 3) [ 1884.420023] wlan0: authentication with 48:5b:39:e7:25:5e timed out Any assistance would be appreciated as I have been trying to get this machine online for several weeks now to no avail.

  • Windows XP problems displaying internet browser backgrounds correctly

    - by Samurai Waffle
    My friend has a Windows XP computer that doesn't show the colored background on pages, it's always white. On top of that some pictures won't show up, there will just be an empty white frame. Also when you left click on a folder, instead of opening it up, it opens up a new window that turns out to be the search results window. I've never heard of these problems before, and I can't find any information on the internet about it. I assume it's a virus deeply imbedded into the system, but no virus scanner has found it. Thanks for the help!

  • The PATRIOT Act and how it relates to the Internet

    The subject of the Internet and anonymity is a very sticky situation for me because I primarily develop web applications for a living.  As a part of my job I have to track users as they enter, navigate and leave specific applications. The level of tracking depends on where the user goes within a website.  The basic information that I capture includes the user’s IP address, browser type, operating system, the date/time they entered the site and the URL from which the user was referred to the website. In addition to the custom logging that is placed on the website, web servers also have methods of logging built-in as well. Web server logging allows companies to have a central repository to store all user activity across the entire server. Not to mention that they can also create a central repository that allows multiple servers to store log files in one location. This allows users to be tracked across multiple servers as they browse website located on a specific collection of servers that host multiple websites. All this being said there are methods to attempt to protect your privacy by using proxy servers and increasing your browser security levels, but that will only limit the amount of logging not eliminate it. I have to agree with Traynor when he states that the PATRIOT Act eviscerates the constitutional protections of anonymous communication on the Internet. Therefore, given the recent passage and implementation of the PATRIOT Act, the constitutional guarantees of the right to anonymity have been severely compromised. I think that the PATRIOT Act is a direct violation of our first amendment rights because it allows for the government to directly monitor any and all activity on the internet including communications, usage, and transactions that can occur.  This opens the door to scrutiny and persecution of individuals who are not in line with the government’s beliefs and actions. If England had this type of monitoring capabilities during the revolutionary war, I believe it would have been almost impossible to succeed from England.

  • Future of WPF and free controls ? [closed]

    - by Justin
    I am willing to work on a personal project that I would like to release publicly. I am working with Silverlight and have experience with XAML, as it is my full-time job. It is enjoyably for me to create UIs in Blend and XAML. I am also a big fan of C# language. I don't know what I would do without LINQ now. Anyways, I was looking at using WPF for my personal project. It seems that a lot of the controls out on the web are pay for items. The only place I have found to have a significant number of free controls is the WPF extended framework on codeplex. I want to make a financial application and need a powerful datagrid type of control that will allow me to enter transaction data. I haven't found such control for free in the net. It doesn't seem like there is much free community libraries/controls out there for Microsoft products. So, I was wondering if WPF would be the right way for me to go. I couldn't find any information on WPF usage in Windows 8, which coming very soon. I don't know Microsoft's plans for this technology. Would it be a better idea to use something different for the UI instead of WPF?

  • A little tidbit on Team Build 2010 and error MSB3147

    - by Enrique Lima
    The problem? Performing a build on a ClickOnce solution would not be successful due to the setup.bin not being located. Ok, now what? Researched from corner to corner, install, re-install, update.  Found some interesting posts to fix the issue, but most of them were focused on Team Foundation Server/Team Build 2008, and some other on 2005.  The other interesting tidbit was the frequent indication to modify the registry to help Team Build find the bootstrapper. Background info:  This was a migration I posted about a few days ago, a 32 bit TFS implementation to a full 64 bit TFS implementation.  Now, the project has binaries and dependencies on X86 (This piece of information became essential to moving from a failed build to a successful build). So, what’s the fix? The trick in this case was to go back into the Build Type and check the properties/configuration.  Upon further investigation, I found the following:  Once you Edit the Build Definition, then select Process, expand 3. Advanced and look for MSBuild Platform, switch from Auto to X86.  Ran the Build, and success!

  • MSCC: Career & IT Fair 2014

    Already a couple of weeks ago, I've been addressed by Ibraahim and Yunus to see whether it would be interesting to participate in the 1st Career & IT Fair organised by the UoM Computer Club. Well, luckily we met at the Global Windows Azure Bootcamp and I wasn't too sure whether it would be possible for me to attend after all. The main reason is given because of work demand and furthermore due to the fact that the Mauritius Software Craftsmanship Community currently has no advertising material at all. Here's the brief statement of the event: "The UOM Students' Computer Club in collaboration with the UOM Students' Union and UOM CSE Department is organising a 'Career & IT Fair' on the 23rd and 24th April 2014. This event has for objective to provide a platform to tertiary students, secondary students as well as vocational students, the opportunity to meet job recruiters." Luckily, I was reminded that the 23rd is a Wednesday, and therefore I decided that it might be interesting to move our weekly Code & Coffee session to the university and hence be able to attend the career fair. As it turned out it was a great choice and thankfully Pritvi, Nadim as well as Ishwon volunteered to be around at the "community booth". Thankfully, the computer club gave us - the MSCC and the LUGM - one of their spaces in the lobby area of the Paul Octave Wiéhé Auditorium. My impression about the event Very well and professionally organised. Seriously, the lads over at the UoM Computer Club did a great job in organising their 2 days event, and felt very comfortable at any time. Actually, it was kind of amusing to some of the members constantly running around and checking everything. Even though that the whole process went smooth and easy off the hand. There were a couple of interesting pieces of information and announcements during the opening ceremony. For example, the Computer Science faculty is a very young one and has been initiated back in 1988 only - just by 4 staff members at that time. Now, after 25 years they have achieved quite a lot and there are currently 1.000+ active students attending the numerous lectures and courses. But there is no room to rest on previous achievements, and I was kind of surprised to hear that there are plans to extend the campus, and offer new lectures in the fields of nanotechnology, big data handling, and - crossing fingers - the introduction and establishment of a space control centre. Mauritius is already part of the Square Kilometre Array (SKA) and hopefully there will be more activities into that direction in the near future. Community - Awareness and collaboration As stated earlier, I could only spent one morning but luckily other members of the MSCC and the LUGM stayed during the whole two days and provided answers to any interested person. As for me, I took the opportunity to get in touch with the other companies in the lobby. Mainly, to create some awareness about our IT communities but also to see whether there might be options for future engagement in common activities, too. So far, I was able to speak to representatives of the following companies: ACCA Mauritius Business at Work Infomil LinkByNet Microsoft Indian Ocean Islands & French Pacific Spherinity Training Institute Spoon Consulting Ltd. State Informatics Ltd. Unfortunately, I only had a quick chat with an HR representative of LinkByNet but I fully count on our MSCC members like Nitin or LUGM member Ronny to spread our intentions over there.  So far, all of the representatives were really interested in our concepts and activities and I'm currently catching up with an introduction flyer for the MSCC that I'm going to send out to all those contacts via mail. It would be great to have more craftsmen as well as professional support on board. Some pictures from the event MSCC: Fantastic outlook for the near future. Announcements were made on Big data, nanotechnology, and space control centre in Mauritius. Interesting! MSCC: The lobby area was cramped with students. Great way to exchange and network. Good luck to all candidates! Passing the relay staff to... I recommend you to continue to read about the first Career & IT Fair on Ish's blog. He has a great summary and more details on those two days of IT activities than I have. Thanks and feel free to leave a comment (or two)...

  • Unable to configure DD-WRT SNMP monitoring with Zabbix

    - by Jien Wai
    Installed Zabbix on Ubuntu but not sure what setting I missed. Base on my concept, I would like to using SNMP to monitoring DD-WRT router which it using SNMP service. I did enable to SNMP service at DD-WRT router page. And also created a host at Zabbix with included DD-WRT template. After I done it I still unable to get any connection/information at Zabbix which mean the router doesn't communicate with Zabbix. The above picture is my DD-WRT's SNMP configuration. http://img13.imageshack.us/img13/2228/rhj2.png Also this is the Zabbix configuration which I have created the service to monitoring my DD-WRT router. http://imageshack.us/a/img853/7311/hlpr.png

  • Camera field of view: 3D projections & trigonometry

    - by Thomas O
    Okay, here goes. I have a camera at (Xc, Yc, Zc.) The Xc and Yc coordinates are latitude/longitude, and the Zc coordinate is an altitude in metres. I have a point at (Xp, Yp, Zp) and a field of view on the camera (Th1, Th2) - where Th1 is horizontal FOV and Th2 is vertical FOV. Given this information, I'd like to: test if the point is visible (i.e. in the camera's FOV) project the point as the camera would see it I've figured out already that the camera's horizontal view at any given distance is tan(Th1) * distance, but I don't know how to test if the point is visible. Accuracy is not critical. I would prefer a simple solution over a complicated solution, if it works well enough. The computations will be performed by a small microcontroller, which isn't very fast at things like trig functions. P.S. this is not homework, I'm doing this for some game development. It will be integrated with the real world, hence the latitude/longitude/altitude. It involves flying real RC planes through virtual hoops (or chasing virtual targets), so I have to project the positions of these hoops on a display.
