  • NodeJS Supervisord Hashlib

    - by enedebe
    I have an problem with my NodeJS app. The problem is the include of the library Hashlib I've followed more than 10 times the instructions to install. Get a clone of the repo, do make and make install. NodeJS is installed in default path, and that's the tricky point: When I launch node app.js it works, perfectly. The problem starts when I configured my Supervisord to run with the same user, with the same config file as I have in other systems working, and I get that NodeJS can't find hashlib. module.js:337 throw new Error("Cannot find module '" + request + "'"); ^ Error: Cannot find module 'hashlib' I'm getting crazy, what can I do?! Why my user launching node from the console works great, but not the supervisord? Thanks!

  • How do I choose the scaling factor of a 3D game world?

    - by concept3d
    I am making a 3D tank game prototype with some physics simulation, am using C++. One of the decisions I need to make is the scale of the game world in relation to reality. For example, I could consider 1 in-game unit of measurement to correspond to 1 meter in reality. This feels intuitive, but I feel like I might be missing something. I can think of the following as potential problems: 3D modelling program compatibility. (?) Numerical accuracy. (Does this matter?) Especially at large scales, how games like Battlefield have huge maps: How don't they lose numerical accuracy if they use 1:1 mapping with real world scale, since floating point representation tend to lose more precision with larger numbers (e.g. with ray casting, physics simulation)? Gameplay. I don't want the movement of units to feel slow or fast while using almost real world values like -9.8 m/s^2 for gravity. (This might be subjective.) Is it ok to scale up/down imported assets or it's best fit with a world with its original scale? Rendering performance. Are large meshes with the same vertex count slower to render? I'm wondering if I should split this into multiple questions...

  • Should I go with OpenGL to see my future in Game Development industry? [closed]

    - by Priyank
    Possible Duplicate: Should I continue studying OpenGL or just switch to DirectX to give me a better chance of landing a job in the game industry? I tried Google but found quite old articles, so I am in search of an answer in context to year 2012. Hi all, I don't know if you will consider this question appropriate for this community but I am constantly searching for a perfect answer. What I have seen is that most of the games that are released these days are DirectX 1x based. Except for few games like Starcraft or Diablo which don't have high end graphics are using OpenGL. So I have few questions to ask. The platforms i would like to target are PC (windows), Xbox 360 and PS3 (must). Should I go with learning OpenGL to see my future in game development industry? Or should I shift to Directx? If I learn OpenGL first, will it be difficult to learn direcx then? Which API is most suitable for indie development? Which one of the two API's are better from coder's (programmer's) point of view? Like OOP and style of coding. Is openGL being cross platform should be the only reason to choose it over Directx? Even when vendors are not providing enough stable drivers for it. Thanks in advance. I have read this post, but I have few questions. Should I continue studying OpenGL or just switch to DirectX to give me a better chance of landing a job in the game industry?

  • boot up fails. drops to initramfs prompt 12.04

    - by dpm
    I am running an HP pavilion dv6000 dual boot win7 and Ubuntu 12.04. (well, up until today). after a reboot, the boot process drops to the busy box shell and i end up at the prompt: BusyBox v1.18.5 (Ubuntu 1:1.18.5-1ubuntu4) built-in shell (ash) Enter 'help' for a list of built-in commands. (initramfs) Ive been researching others who have had this same problem, but haven't been able to find any of those solutions to work for me. I tried the method described here: http://www.proposedsolution.com/solutions/ubuntu-booting-to-initramfs-prompt/ and after the final command mount -t ntfs-3g /dev/sda1 /root -o force it does nothing and gives me another (initramfs) prompt. I can boot to a live CD (USB) and get to a terminal, but it doesn't seem to do much good, as I can see the /dev/sda1 in the ls command, but it doesn't recognize it when I try to cd to it. My command line skills are very green, and am just starting to grasp them. One more question: using the command fdisk -l how can I tell which mount point (sda1/sda2) is my windows partition and which one is Ubuntu? Any help? I'm in a bit over my head right now...

  • Guest blog: A Closer Look at Oracle Price Analytics by Will Hutchinson

    - by Takin Babaei
    Overview:  Price Analytics helps companies understand how much of each sale goes into discounts, special terms, and allowances. This visibility lets sales management see the panoply of discounts and start seeing whether each discount drives desired behavior. In Price Analytics monitors parts of the quote-to-order process, tracking quotes, including the whole price waterfall and seeing which result in orders. The “price waterfall” shows all discounts between list price and “pocket price”. Pocket price is the final price the vendor puts in its pocket after all discounts are taken. The value proposition: Based on benchmarks from leading consultancies and companies I have talked to, where they have studied the effects of discounting and started enforcing what many of them call “discount discipline”, they find they can increase the pocket price by 0.8-3%. Yes, in today’s zero or negative inflation environment, one can, through better monitoring of discounts, collect what amounts to a price rise of a few percent. We are not talking about selling more product, merely about collecting a higher pocket price without decreasing quantities sold. Higher prices fall straight to the bottom line. The best reference I have ever found for understanding this phenomenon comes from an article from the September-October 1992 issue of Harvard Business Review called “Managing Price, Gaining Profit” by Michael Marn and Robert Rosiello of McKinsey & Co. They describe the outsized impact price management has on bottom line performance compared to selling more product or cutting variable or fixed costs. Price Analytics manages what Marn and Rosiello call “transaction pricing”, namely the prices of a given transaction, as opposed to what is on the price list or pricing according to the value received. They make the point that if the vendor does not manage the price waterfall, customers will, to the vendor’s detriment. It also discusses its findings that in companies it studied, there was no correlation between discount levels and any indication of customer value. I urge you to read this article. What Price Analytics does: Price analytics looks at quotes the company issues and tracks them until either the quote is accepted or rejected or it expires. There are prebuilt adapters for EBS and Siebel as well as a universal adapter. The target audience includes pricing analysts, product managers, sales managers, and VP’s of sales, marketing, finance, and sales operations. It tracks how effective discounts have been, the win rate on quotes, how well pricing policies have been followed, customer and product profitability, and customer performance against commitments. It has the concept of price waterfall, the deal lifecycle, and price segmentation built into the product. These help product and sales managers understand their pricing and its effectiveness on driving revenue and profit. They also help understand how terms are adhered to during negotiations. They also help people understand what segments exist and how well they are adhered to. To help your company increase its profits and revenues, I urge you to look at this product.

  • Implementing Light Volume Front Faces

    - by cubrman
    I recently read an article about light indexed deferred rendering from here: http://code.google.com/p/lightindexed-deferredrender/ It explains its ideas in a clear way, but there was one point that I failed to understand. It in fact is one of the most interesting ones, as it explains how to implement transparency with this approach: Typically when rendering light volumes in deferred rendering, only surfaces that intersect the light volume are marked and lit. This is generally accomplished by a “shadow volume like” technique of rendering back faces – incrementing stencil where depth is greater than – then rendering front faces and only accepting when depth is less than and stencil is not zero. By only rendering front faces where depth is less than, all future lookups by fragments in the forward rendering pass will get all possible lights that could hit the fragment. Can anyone explain how exactly you need to render only front faces? Another question is why do you need the front faces at all? Why can't we simply render all the lights and store the ones that overlap at this pixel in a texture? Does this approach serves as a cut-off plane to discard lights blocked by opaque geometry?

  • MS Word - Close Word when you close the last open document **using keyboard**

    - by Chad
    In MS Word, by default, you can use: Ctrl+F4 to close Word Ctrl+W to close the current document Is it possible to make Word close when you close the last open document? For instance, in Chrome, if you keep hitting Ctrl+W you'll eventually close the last tab, which will also close Chrome. I'd like the same functionality with Word (and the other Office products) where I can just keep closing documents until I close the last one, at which point the application closes. Unfortunately, Ctrl+W doesn't close Word, even when there are no documents open.

  • Oracle Delivers Special Recognition for Specialized Partners

    - by michaela.seika(at)oracle.com
    Since announcing Oracle PartnerNetwork Specialized (OPN Specialized) in October 2009, Oracle has been focused on building a program that first enables solution providers to become highly skilled Oracle partners who deliver value to customers and that then recognizes and rewards their achievements in a meaningful way. Today the company unveiled new benefits reserved for partners who have achieved one or more of the over 50 specializations currently available. The benefits demonstrate Oracle's commitment to showcase these valued partners to three key audiences: customers, other partners, and Oracle employees.With today's launch of www.oracle.com/specialized Oracle has taken what IDC believes is a first of its kind approach to putting top partners front and center with customers and prospects. While most vendors offer a business partner finder tool on their website none has gone as far as Oracle with the creation of this new site dedicated to the promotion of Specialized Partners. The tag lines - "Recognized by Oracle, Preferred by Customers" and "Specialized. Recognized. Preferred." gets right to the point - these are the solution providers with which customers should choose to engage. The contents of the page offer multiple proof points to justify the marketing phrases.One of the benefits Oracle offers its Specialized Partners is video creation and placement. While Oracle works with partners to create informal or "guerilla" videos which often are placed on YouTube to generate awareness and buzz, the company also produces professional videos for its partners. The greatest value the partner receives from this benefit isn't the non-trivial production costs that Oracle covers but instead the prominent exposure Oracle gives the finished product. Partner videos are featured on www.oracle.com/specialized, used as part of monthly OPN Specialized Partners monthly webcasts, placed on a customer facing website, the Oracle Media Network, which includes several partner sites such as PartnerCast. A solution provider gains a great deal of credibility when they can send a prospect to an Oracle website where they are featured. Read the full article here.

  • How can I diagnose a "502 Bad Gateway" response from an Apache/Tomcat configuration?

    - by Structure
    I just finished up configuring a fairly default configuration of Tomcat. My Apache configuration was pre-existing and post-tomcat it still has no issues. I am using mod_jk to (if I am saying this correctly) interface between Apache and Tomcat and have my conf files setup for my workers, etc. I put my test file (Simply: http://tomcat.apache.org/tomcat-4.1-doc/appdev/sample/web/hello.jsp) into my tomcat/webapps/ directory and then call it via http://localhost/test/hello.jsp. From here Apache returns a "502 Bad Gateway" response. I confirmed this via the Apache logs, but beyond that I have no idea how to diagnose the issue. I assume the 502 is because Tomcat did not respond. I'd like to confirm if Tomcat received the request, but cannot locate the log file. At this point I had thought my installation was complete, so not sure where to go from here. Any input would be appreciated.

  • Greiner-Hormann clipping problem

    - by Belgin
    I have a set of planar polygons in 3D space defined by their vertices in counterclockwise order. Let's define the 'positive face' as being the face of the 3D polygon such as when observed, the vertices appear in counterclockwise order, and the 'negative face', the face which when observed, the vertices appear in clockwise order. I'm doing perspective projection of the set of polygons onto a projection polygon defined by the points in this order: (0, h, 0), (0, 0, 0), (w, 0, 0), and (w, h, 0), where w and h are strictly positive integers. The positive face of this projection polygon is oriented towards positive Z, and the camera point is somewhere at (0, 0, d), where d is a strictly negative number. In order to 'clip' the projected polygons into the projection polygon, I'm applying the Greiner-Hormann (PDF) clipping algorithm, which requires that the clipper and the to-be-clipped polygons be in the same order (i.e. clockwise or counterclockwise). My question is the following: How can I determine whether the projected face of the 3D polygon is the negative or the positive one? Meaning, how do I find out if I have to work with the vertices in normal or inverted order for the algorithm to work? I noticed that only if the 3D polygon is facing the projection polygon with its negative face, both of them are in the same order (counterclockwise), otherwise, a modification needs to be done. Here is a picture (PNG) that illustrates this. Note that the planes described by the polygon from the set and the projection polygon may not always be parallel.

  • Basket Analysis with #dax in #powerpivot and #ssas #tabular

    - by Marco Russo (SQLBI)
    A few days ago I published a new article on DAX Patterns web site describing how to implement Basket Analysis in DAX. This topic is a very classical one and is also covered in the many-to-many revolution white paper. It has been also discussed in several blog posts, listed here in historical order: Simple Basket Analysis in DAX by Chris Webb PowerPivot, basket analysis and the hidden many to many by Alberto Ferrari Applied Basket Analysis in Power Pivot using DAX by Gerhard Brueckl As usual, in DAX Patterns we try to present the required DAX formulas in a way that is easy to adapt to specific models. We also try to show a good implementation from a performance point of view. Further optimizations are always possible in DAX. However, in order to keep the model simple to adapt in different scenarios, we avoid presenting optimizations that would require particular assumptions or restrictions on the data model. I hope you will find the Basket Analysis pattern useful. Even if you do not need it today, reading the DAX formula is a good exercise to check your knowledge of evaluation contexts in DAX. For example, describing how does it work the following expression is not a trivial task! [Orders with Both Products] := CALCULATE (     DISTINCTCOUNT ( Sales[SalesOrderNumber] ),     CALCULATETABLE (         SUMMARIZE ( Sales, Sales[SalesOrderNumber] ),         ALL ( Product ),         USERELATIONSHIP ( Sales[ProductCode], 'Filter Product'[Filter ProductCode] )     ) ) The good news is that you can use the patterns even if you do not really understand all the details of the DAX formulas you are using! Any feedback on this new pattern is very welcome.

  • back-end SQL server 2005 databases for website

    - by Datapimp23
    Hi, We're migrating an existing IIS website + MS SQL 2005 database (on the same server) to a new test set-up. The existing set-up is too slow. I want one ISS server and 2 X MS SQL server 2005. One live DB server for the website queries (inserts, updates) and another for backups, reports or stored procedures. So the live DB should be more aimed at performance. The other doesn't even need to be synced instantly. What is the best way in SQL server 2005 to set this up. Can somebody point me in the right direction and give me some pointers. Thanks

  • Eclipse no longer useful

    - by dgood1
    When I got my Eclipse from the Ubuntu Software Center, it was good and worked fine. I could work on Java projects fine. This week I was required to add ADT and tried the ADT-bundle, assuming it had everthing I needed, seeing that the SDK had more steps. So now, I can create Android apps using the ADT-bundle. I tried to work on my java projects again and I now discovered: I can't run my java projects: "The selection cannot be launched. And there are no recent launches." error. I also believe Eclipse doesn't know it's a java program because it all in black and white. Not the usual green/blue/red/black things when making comments, variables and Strings. I can't make new projects of ANYTHING unless I use the adt-bundle. New project only offers CVS (whatever that is) My perspectives seem limited. I remembered more choices and now I'm limited to [Java], Resource, CVS Repository, debug, Team Sync. I was told to be able to use perspectives to swap between Android and Java developing. Even after the ADT installation using "Install new Software",nothing. I can't uninstall/purge/remove Eclipse via the terminal. I tried removing it then reinstalling it via the Ubuntu Software Cetner. No results other than it's temporary removal. (Possibly unrelated) A large number of repositories are not found when updating Eclipse. (See Step 8 in Summary of what I did...) Although, on checking the versions and installation history, I confirmed Android and Java are installed. It probably just doesn't know it's there. Eclipse Indigo: Version: 3.7.2 Build id: I20110613-1736 Summary of what I did before and during the problem: Downloaded adt-bundle. Attempted instructions from teacher. (Install new Software) (Failed but other than an annoying "can't find repository" during each update, no damage to report) (Fixed) Ran "eclipse" executable from the adt-bundle. Updated Eclipse. (After restart, I noticed the problem) NOTE: other than window arrangement, I had no customizations. Played around with the Windowspreferences and Projectpropertied. Restored to default settings after no results. Tried "apt-get purge eclipse". Couldn't find Eclipse so, nothing happened. Used Software center. No results. Tried swapping workspaces. I tried different folder, deeper folder, renaming. All return the same problem. Deleted adt-bundle (browsed folders then delete). Got Adt-sdk only. Installed. Can't find any changes other than some disk space usage. Of course, I can't make Android apps until I unzip the bundle again. WindowsPreferencesInstall/UpdateAvailable Software Sites, Checked as many repositories as possible, then updated. Still nothing. I'm about to get a second try on uninstalling it, because I think my last action will just be taking up space. But I'll wait for tomorrow, in case the answer will help. Any thoughts?

  • How to fetch only the sprites in the player's range of motion for collision testing? (2D, axis aligned sprites)

    - by Twodordan
    I am working on a 2D sprite game for educational purposes. (In case you want to know, it uses WebGl and Javascript) I've implemented movement using the Euler method (and delta time) to keep things simple. Now I'm trying to tackle collisions. The way I wrote things, my game only has rectangular sprites (axis aligned, never rotated) of various/variable sizes. So I need to figure out what I hit and which side of the target sprite I hit (and I'm probably going to use these intersection tests). The old fashioned method seems to be to use tile based grids, to target only a few tiles at a time, but that sounds silly and impractical for my game. (Splitting the whole level into blocks, having each sprite's bounding box fit multiple blocks I might abide. But if the sprites change size and move around, you have to keep changing which tiles they belong to, every frame, it doesn't sound right.) In Flash you can test collision under one point, but it's not efficient to iterate through all the elements on stage each frame. (hence why people use the tile method). Bottom line is, I'm trying to figure out how to test only the elements within the player's range of motion. (I know how to get the range of motion, I have a good idea of how to write a collisionCheck(playerSprite, targetSprite) function. But how do I know which sprites are currently in the player's vicinity to fetch only them?) Please discuss. Cheers!

  • How can I install an Apple Magic Trackpad on a PC without Boot Camp?

    - by rymo
    I have a Apple Magic Trackpad and I'd like to use it with my PC. I have no other Apple hardware besides the Trackpad. I do not have OSX and thus no Boot Camp CD. The Trackpad uses Bluetooth and will pair with Windows 7 without specific drivers (appears as an HID-Compliant Mouse), but all it will do is point and left click (physical click, no touch tap). With Apple's Windows driver update, I should be able to achieve: Tap to click Dragging Drag lock Secondary click Two-finger scrolling Two-finger secondary tap/click But how can I obtain this driver without Boot Camp installed? Apple's Boot Camp update EXE will not install on my PC (non-Apple hardware).

  • Direct DB to Web Server connection

    - by Joel Coel
    I have a database server sitting right underneath a virtual machine host server in the rack, and this vm host is primarily responsible for servers hosting a couple different web sites and app servers that all talk to databases on the other server. Right now both servers are connected to the same switch, and I'm pretty happy with the pathing. However, both servers also have an unused network port. I wondering about the potential benefits of using a short crossover or normal+auto mdix network cable to connect these two servers together directly. Is this a good idea, or would I be doing something that won't show much benefit and is just likely to trip up a future admin who's not looking for this? The biggest weakness I can see right now is that this would likely require a code change for each vm app to point to the new IP of the database server on this private little network, and if I have a problem with the virtual machine host and have to spin up it's guests elsewhere while I fix it I'll have to change this back before things will work.

  • Is it possible to retrieve lost Windows XP profile information?

    - by Simon Shaw
    I'm running Windows XP Professional on a PC which is less than a year old. About 3 months ago I got an error on boot saying windows could not find my profile. At this point it created a temp one. On this occasion I copied the temp data back into my existing profile and carried on using it. After another month it died again and, once again set me up a temp user. Each time this happens I lose everything related to my profile (desktop, start menu, etc). I ran checks on the hard disk and these suggested nothing was wrong so this seems a software issue not a disk problem. On the advice of my computer manufacturer I am now considering reinstalling Windows but just wanted to check if there's any other ideas for things I might be able to try. Any suggestions for what could be causing the problem would also be gladly appreciated.

  • Create 301 Redirection in Amazon Route 53 for Wildcard Subdomains

    - by Eric Yin
    My domain name hosted on Route 53 DNS. Amazon has a guide to do 301 redirection for www. To naked domain by point www. version to a S3 static website with 301 setted up. My question is, how can I have *.domain.com all have 301 redirec to naked domain name. I guess either: Some way to get all wildcard subdomains end up into one S3 bucket, how? Or: Use CloudFront on the www. version S3 site and put wildcard subdomains on the CloudFront, but how? Or: There's some hidden settings just lies on Router 53, then where? Or: use EC2, better not suggest me this, too costing for this task. Please advice.

  • Cocos2d sprite's parent not reflecting true scale value

    - by Paul Renton
    I am encountering issues with determining a CCSprite's parent node's scale value. In my game I have a class that extends CCLayer and scales itself based on game triggers. Certain child sprites of this CCLayer have mathematical calculations that become inaccurate once I scale the parent CCLayer. For instance, I have a tank sprite that needs to determine its firing point within the parent node. Whenever I scale the layer and ask the layer for its scale values, they are accurate. However, when I poll the sprites contained within the layer for their parent's scale values, they always appear as one. // From within the sprite CCLOG(@"ChildSprite-> Parent's scale values are scaleX: %f, scaleY: %f", self.parent.scaleX, self.parent.scaleY); // Outputs 1.0,1.0 // From within the layer CCLOG(@"Layer-> ScaleX : %f, ScaleY: %f , SCALE: %f", self.scaleX, self.scaleY, self.scale); // Output is 0.80,0.80 Could anyone explain to me why this is the case? I don't understand why these values are different. Maybe I don't understand the inner design of Cocos2d fully. Any help is appreciated.

  • Guaranteeing ACID properties for InnoDB databases.

    - by plinehan
    What steps must one take to ensure that an otherwise defaultly-configured InnoDB server is truly ACID compliant? The InnoDB configuration page mentions that the hardware itself must be configured to honor fsync calls, i.e. disable any write-back caches. This page mentions some other concerns, but may be conflating the binary log and the InnoDB log, and may be a bit out of date regarding default settings for MySQL 5.x. Upon reading the binary log document page it would seem that the "sync_binlog=1" setting is not required for ACID properties in general, only for ACID properties vis a vis point-in-time recovery and replication. So, is disabling write-back disk caching sufficient, or are there other settings that must be tweaked?

  • How to Open Any Folder as a Project in the NetBeans Platform

    - by Geertjan
    Typically, as described in the NetBeans Project Type Tutorial, you'll define a project type based on the presence of a file (e.g., "project.xml" or "customer.txt" or something like that) in a folder. I.e., if the file is there, then its parent, i.e., the folder that contains the file, is a project and should be opened in your application. However, in some scenarios (as with the HTML5 project type introduced in NetBeans IDE 7.3), the user should be able to open absolutely any folder at all into the application. How to create a project type that is that liberal? Here you go, the only condition that needs to be true is that the selected item in the "Open Project" dialog is a folder, as defined in the "isProject" method below. Nothing else. That's it. If you select a folder, it will be opened in your application, displaying absolutely everything as-is (since below there's no ProjectLogicalView defined): import java.beans.PropertyChangeListener; import java.io.IOException; import javax.swing.Icon; import org.netbeans.api.project.Project; import org.netbeans.api.project.ProjectInformation; import org.netbeans.spi.project.ProjectFactory; import org.netbeans.spi.project.ProjectState; import org.openide.filesystems.FileObject; import org.openide.loaders.DataFolder; import org.openide.loaders.DataObjectNotFoundException; import org.openide.nodes.FilterNode; import org.openide.util.Exceptions; import org.openide.util.ImageUtilities; import org.openide.util.Lookup; import org.openide.util.lookup.Lookups; import org.openide.util.lookup.ServiceProvider; @ServiceProvider(service = ProjectFactory.class) public class FolderProjectFactory implements ProjectFactory { @Override public boolean isProject(FileObject projectDirectory) { return DataFolder.findFolder(projectDirectory) != null; } @Override public Project loadProject(FileObject dir, ProjectState state) throws IOException { return isProject(dir) ? new FolderProject(dir) : null; } @Override public void saveProject(Project prjct) throws IOException, ClassCastException { // leave unimplemented for the moment } private class FolderProject implements Project { private final FileObject projectDir; private Lookup lkp; private FolderProject(FileObject dir) { this.projectDir = dir; } @Override public FileObject getProjectDirectory() { return projectDir; } @Override public Lookup getLookup() { if (lkp == null) { lkp = Lookups.fixed(new Object[]{ new Info(), }); } return lkp; } private final class Info implements ProjectInformation { @Override public Icon getIcon() { Icon icon = null; try { icon = ImageUtilities.image2Icon( new FilterNode(DataFolder.find( getProjectDirectory()).getNodeDelegate()).getIcon(1)); } catch (DataObjectNotFoundException ex) { Exceptions.printStackTrace(ex); } return icon; } @Override public String getName() { return getProjectDirectory().getName(); } @Override public String getDisplayName() { return getName(); } @Override public void addPropertyChangeListener(PropertyChangeListener pcl) { //do nothing, won't change } @Override public void removePropertyChangeListener(PropertyChangeListener pcl) { //do nothing, won't change } @Override public Project getProject() { return FolderProject.this; } } } } Even the ProjectInformation implementation really isn't needed at all, since it provides nothing more than the icon in the "Open Project" dialog, the rest (i.e., the display name in the "Open Project" dialog) is provided by default regardless of whether you have a ProjectInformation implementation or not.

  • Simple monitoring utility with up/down statuses of the host's network connectivity and services

    - by Beaming Mel-Bin
    We've looked at many monitoring tools (SolarWinds, Zabbix, Nagios) through out the last 10 years but they never took hold because they are overly complicated. I am willing to try them again or something new at this point but with a much simpler goal: ping to check up and down of host tcp probes to test up and down of service notifications via e-mail web GUI prefer an OSS solution Wanted to know if someone has any recommendations on this. This could be a Windows or Linux application. Preferably without the reqirement of agents. I don't even need SNMP support but that may be nice for expanding once we have the above mentioned bare minimum in place.

  • Ubuntu impossible to install: "unable to find a medium containing a live filesystem"

    - by Lorenzo
    Yes, I have read questions and answers with similar titles for this issue, which prevented me from installing Ubuntu for several MONTHS now, trying to figure it out. I have a MacBookPro with triple partition (one for Mac Snow Leopard, one for Windows 7, one for Linux) created with reFIT firmware (not BootCamp). I set up the system according to these instructions for reFIT: http://lifehacker.com/5531037/how-to-triple+boot-your-mac-with-windows-and-linux-no-boot-camp-required Now. There is a free partition ready to accept Linux into its arms, but Linux does not want to participate. Most answers to the issue "unable to find a medium containing a live filesystem" point to changing the BIOS booting system (which I don't know how to do, especially using this reFIT booting system), and to changing the socket of the USB (which does not concern me, since I am using a CD, actually I tried with a CD, then with a DVD, since a blank CD is only 700MB while the iso image file of Ubuntu is about 731MB). Anyway. This is what happens: I am in the Mac system (using the Mac partition) I insert the DVD with the burned image of Ubuntu (yes I have tried burning it again and agin on both CD and DVD blank discs). I restart the computer. When reFIT loads, I hold down the ALT key until the CD image appears. I select it, and hit Enter. A small Ubuntu icon appears at the bottom of the screen. Then a Ubuntu sign appears in the middle of the screen with small dots underneath, lighting up progressively over and over to indicate it's loading. Then everything turns black and the following message appears, at the end of a few lines of text: "unable to find medium with live file system". Please provide very practical suggestions on what to do to an unexperienced wannabe Ubuntu very patient user. Please start by saying how do I access the BIOS setup from reFIT bootup, and exactly what and why I need to try and change. (Will this mess up my reFIT bootup?) And anything else I need to do to finally be able to install Ubuntu. Thanks

  • Can't enable wireless lan on Fujitsu Siemens A1665G with Ubuntu 11.10 installed

    - by Theo
    I saw my old Notebook yesterday and wanted to make that work again. On Windows XP the wireless worked still fine. Then I installed new Ubuntu 11.10 32bit and I'm sadly not able to make the wireless enabled. [I replaced Win XP entirely] lspci lists following network: 08:0a.0 Network controller: Broadcom Corporation BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller (rev 02) So after recommendation from this link I installed the b43 firmware module. iwconfig prints the following: wlan0 IEEE 802.11bg ESSID:off/any Mode:Managed Access Point: Not-Associatd Tx-Power=off Retry long limit:7 RTS thr:off Fragment thr:off Power Management: off As you can see, my wireless lan adapter is not turned on. sudo iwconfig wlan0 txpower auto Doesn't change anything. Then I tried to make it work with rfkill. rfkill list 0: phy0: Wirless LAN Soft blocked: no Hard blocked: yes sudo rfkill unblock all rfkill list 0: phy0: Wireless LAN Soft blocked: no Hard blocked: yes remains the same. The question is now, how I could enable the hard blocked wireless LAN. There is no hardware switch for wlan integrated. However there is a button to change the state. I always thought this would be software sided, but it seems to make some hardware changes as well... The wireless LED is also not blinking (as it did on windows xp) I reset bios and searched for some settings in there, but it has only a few options and nothing to do with wireless settings, nothing works here.. At last I tried to install the acer hotkeys but I was not able to manage that. I installed the acerhkgui package, but in initializing progress, it was not able to compile acer hotkeys for my machine. There was a message that asm/linkage.h was not found while compiling. Do you have any ideas what I could do to make this hard blocked stuff disabled and my wireless card work? PS: I also tried sudo rm /dev/rfkill and a reboot to reinit that stuff... No success :(
