  • Forensics on Virtual Private servers [closed]

    - by intiha
    So these days with talks about having hacked machines being used for malware spreading and botnet C&C, the one issue that is not clear to me is what do the law enforcement agencies do once they have identified a server as being a source or controller of attack/APT and that server is a VPS on my cluster/datacenter? Do they take away the entire machine? This option seems to have a lot of collateral damage associated with it, so I am not sure what happens and what are the best practices for system admins for helping law enforcement with its job while keeping our jobs!

  • The Grenelle II Act In France: A Milestone Towards Integrated Reporting

    - by Evelyn Neumayr
    By Elena Avesani, Principal Product Strategy Manager, Oracle In July of 2010, France took a significant step towards mandating integrated sustainability and financial reporting for all large companies with a new law called Grenelle II. Article 225 of Grenelle II requires that many listed companies on the French stock exchanges incorporate information on the social and environmental consequences of their activities into their annual reports, as well as their societal commitments for sustainable development. The decree that implements Article 225 of Grenelle II was passed in April 2012. Grenelle II is the strongest governmental mandate yet in support of sustainability reporting. The law defines the phase-in process, with large listed companies expected to comply in their 2012 reports and smaller companies expected to comply with their 2014 annual reports. This extra-financial information will have to be embedded in the annual management report, approved by the Board of Directors, verified by a third-party body and given to the annual general meeting. The subjects that must be reported on are grouped into Environmental, Social, and Governance categories. Oracle solutions can help organizations integrate financial and sustainability reporting and provide a more accurate and auditable approach to collecting, consolidating, and reporting such environmental, social, and economic metrics. Through Oracle Environmental Accounting and Reporting and Oracle Hyperion Financial Management Sustainability Starter Kit organizations can collect environmental, social and governance data and collect and consolidate corporate sustainability reporting data from multiple systems and business units.

  • San Joaquin County, California Wins AIIM 2012 Carl E. Nelson Best Practice Award

    - by Peggy Chen
    Last month, AIIM, the global community of information professionals, announced the winners of the 2012 Carl E. Nelson Best Practices Awards. And San Joaquin County, California won in the small company category for 1-100 employees. The Carl E. Nelson Best Practices Award was established to recognize excellence in the area of information management. "Best practice" denotes a standard of excellence that has been achieved with an organization and refers to a process that can be quantified, adapted and repeated. Like many counties, San Joaquin County, California, was faced with huge challenges due to decreasing funds and staff, including decreased cost of building capability. It needed to streamline processes, cut costs per activity, modernize and strengthen the infrastructure, and adopt new technology and standards such as the National Information Exchange Model (NIEM). The Integrated Justice Information System (IJIS) provides a Web-based system to link more than 650,000 residents, 18 agencies countywide and other law enforcement systems nationwide. The county’s modernization initiative focused on replacing its outdated warrant system, implementing service-oriented architecture (SOA) to simplify integration between county law and justice systems, deploying Business Process Management (BPM), Case Management with content management, and Web technologies from Oracle. A critical part of their success has been the proper alignment of our Strategic Vision to the way the organization was enabled to plan and execute (and continues to execute) their modernization project. Congratulations to San Joaquin County!

  • Extreme Optimization – Numerical Algorithm Support

    - by JoshReuben
    Function Delegates Many calculations involve the repeated evaluation of one or more user-supplied functions eg Numerical integration. The EO MathLib provides delegate types for common function signatures and the FunctionFactory class can generate new delegates from existing ones. RealFunction delegate - takes one Double parameter – can encapsulate most of the static methods of the System.Math class, as well as the classes in the Extreme.Mathematics.SpecialFunctions namespace: var sin = new RealFunction(Math.Sin); var result = sin(1); BivariateRealFunction delegate - takes two Double parameters: var atan2 = new BivariateRealFunction (Math.Atan2); var result = atan2(1, 2); TrivariateRealFunction delegate – represents a function takes three Double arguments ParameterizedRealFunction delegate - represents a function taking one Integer and one Double argument that returns a real number. The Pow method implements such a function, but the arguments need order re-arrangement: static double Power(int exponent, double x) { return ElementaryFunctions.Pow(x, exponent); } ... var power = new ParameterizedRealFunction(Power); var result = power(6, 3.2); A ComplexFunction delegate - represents a function that takes an Extreme.Mathematics.DoubleComplex argument and also returns a complex number. MultivariateRealFunction delegate - represents a function that takes an Extreme.Mathematics.LinearAlgebra.Vector argument and returns a real number. MultivariateVectorFunction delegate - represents a function that takes a Vector argument and returns a Vector. FastMultivariateVectorFunction delegate - represents a function that takes an input Vector argument and an output Matrix argument – avoiding object construction  The FunctionFactory class RealFromBivariateRealFunction and RealFromParameterizedRealFunction helper methods - transform BivariateRealFunction or a ParameterizedRealFunction into a RealFunction delegate by fixing one of the arguments, and treating this as a new function of a single argument. var tenthPower = FunctionFactory.RealFromParameterizedRealFunction(power, 10); var result = tenthPower(x); Note: There is no direct way to do this programmatically in C# - in F# you have partial value functions where you supply a subset of the arguments (as a travelling closure) that the function expects. When you omit arguments, F# generates a new function that holds onto/remembers the arguments you passed in and "waits" for the other parameters to be supplied. let sumVals x y = x + y     let sumX = sumVals 10     // Note: no 2nd param supplied.     // sumX is a new function generated from partially applied sumVals.     // ie "sumX is a partial application of sumVals." let sum = sumX 20     // Invokes sumX, passing in expected int (parameter y from original)  val sumVals : int -> int -> int val sumX : (int -> int) val sum : int = 30 RealFunctionsToVectorFunction and RealFunctionsToFastVectorFunction helper methods - combines an array of delegates returning a real number or a vector into vector or matrix functions. The resulting vector function returns a vector whose components are the function values of the delegates in the array. var funcVector = FunctionFactory.RealFunctionsToVectorFunction(     new MultivariateRealFunction(myFunc1),     new MultivariateRealFunction(myFunc2));  The IterativeAlgorithm<T> abstract base class Iterative algorithms are common in numerical computing - a method is executed repeatedly until a certain condition is reached, approximating the result of a calculation with increasing accuracy until a certain threshold is reached. If the desired accuracy is achieved, the algorithm is said to converge. This base class is derived by many classes in the Extreme.Mathematics.EquationSolvers and Extreme.Mathematics.Optimization namespaces, as well as the ManagedIterativeAlgorithm class which contains a driver method that manages the iteration process.  The ConvergenceTest abstract base class This class is used to specify algorithm Termination , convergence and results - calculates an estimate for the error, and signals termination of the algorithm when the error is below a specified tolerance. Termination Criteria - specify the success condition as the difference between some quantity and its actual value is within a certain tolerance – 2 ways: absolute error - difference between the result and the actual value. relative error is the difference between the result and the actual value relative to the size of the result. Tolerance property - specify trade-off between accuracy and execution time. The lower the tolerance, the longer it will take for the algorithm to obtain a result within that tolerance. Most algorithms in the EO NumLib have a default value of MachineConstants.SqrtEpsilon - gives slightly less than 8 digits of accuracy. ConvergenceCriterion property - specify under what condition the algorithm is assumed to converge. Using the ConvergenceCriterion enum: WithinAbsoluteTolerance / WithinRelativeTolerance / WithinAnyTolerance / NumberOfIterations Active property - selectively ignore certain convergence tests Error property - returns the estimated error after a run MaxIterations / MaxEvaluations properties - Other Termination Criteria - If the algorithm cannot achieve the desired accuracy, the algorithm still has to end – according to an absolute boundary. Status property - indicates how the algorithm terminated - the AlgorithmStatus enum values:NoResult / Busy / Converged (ended normally - The desired accuracy has been achieved) / IterationLimitExceeded / EvaluationLimitExceeded / RoundOffError / BadFunction / Divergent / ConvergedToFalseSolution. After the iteration terminates, the Status should be inspected to verify that the algorithm terminated normally. Alternatively, you can set the ThrowExceptionOnFailure to true. Result property - returns the result of the algorithm. This property contains the best available estimate, even if the desired accuracy was not obtained. IterationsNeeded / EvaluationsNeeded properties - returns the number of iterations required to obtain the result, number of function evaluations.  Concrete Types of Convergence Test classes SimpleConvergenceTest class - test if a value is close to zero or very small compared to another value. VectorConvergenceTest class - test convergence of vectors. This class has two additional properties. The Norm property specifies which norm is to be used when calculating the size of the vector - the VectorConvergenceNorm enum values: EuclidianNorm / Maximum / SumOfAbsoluteValues. The ErrorMeasure property specifies how the error is to be measured – VectorConvergenceErrorMeasure enum values: Norm / Componentwise ConvergenceTestCollection class - represent a combination of tests. The Quantifier property is a ConvergenceTestQuantifier enum that specifies how the tests in the collection are to be combined: Any / All  The AlgorithmHelper Class inherits from IterativeAlgorithm<T> and exposes two methods for convergence testing. IsValueWithinTolerance<T> method - determines whether a value is close to another value to within an algorithm's requested tolerance. IsIntervalWithinTolerance<T> method - determines whether an interval is within an algorithm's requested tolerance.

  • Visual Studio &amp; TFS 11 &ndash; List of extensions and upgrades

    - by terje
    This post is a list of the extensions I recommend for use with Visual Studio 11. It’s coming up all the time – what to install, where are the download sites, last version, etc etc, and thus I thought it better to post it here and keep it updated. The basics are Visual Studio 11 connected to a Team Foundation Server 11. Note that we now are at Beta time, and that also many live in a side-by-side environment with Visual Studio 2010.  The side-by-side is supported by VS 11. However, if you installed a component supporting VS11 before you installed VS11, then you need to reinstall it.  The VSIX installer will understand that it is to apply those only for VS11, and will not touch – nor remove – the same for VS2010. A good example here is the Power Commands. The list is more or less in priority order. The focus is to get a setup which can be used for a complete coding experience for the whole ALM process. The list of course reflects what I use for my work , so it is by no means complete, and for some of the tools there are equally useful alternatives. Many components have not yet arrived with VS11 support.  I will add them as they arrive.  The components directly associated with Visual Studio from Microsoft should be common, see the Microsoft column. If you still need the VS2010 extensions, here they are: The extensions for VS 2010.   Components ready for VS 11, both upgrades and new ones Product Notes Latest Version License Applicable to Microsoft TFS Power Tools Beta 111 Side-by-side with TFS 2010 should work, but remove the Shell Extension from the TFS 2010 power tool first.

  • Fight for your rights as a video gamer.

    - by Chris Williams
    Soon, the U.S. Supreme Court may decide whether to hear a case that could have a lasting impact on computer and video games. The case before the Court involves a law passed by the state of California attempting to criminalize the sale of certain computer and video games. Two previous courts rejected the California law as unconstitutional, but soon the Supreme Court could have the final say. Whatever the Court's ruling, we must be prepared to continue defending our rights now and in the future. To do so, we need a large, powerful movement of gamers to speak with one voice and show that we won't sit back while lawmakers try to score political points by scapegoating video games and treating them differently than books, movies, and music. If the Court decides to hear the case, we're going to need thousands of activists like you who can help defend computer and video games by writing letters to editors, calling into talk radio stations, and educating Americans about our passion for and appreciation of computer and video games. You can help build this movement right now by inviting all your friends and fellow gamers to join the Video Game Voters Network. Use our simple tool to send an email to everyone you know asking them to stand up for gaming rights: http://videogamevoters.org/movement You can also help spread the word through Facebook and Twitter, or you can simply forward this email to everyone you know and ask them to sign up at videogamevoters.org. Time after time, courts continue to reject politicians' efforts to restrict the sale of computer and video games. But that doesn't mean the politicians will stop trying anytime soon -- in fact, it means they're likely to ramp up their efforts even more. To stop them, we must make it clear that gamers will continue to stand up for free speech -- and that the numbers are on our side. Help make sure we're ready and able to keep fighting for our gaming rights. Spread the word about the Video Game Voters Network right now: http://videogamevoters.org/movement Thank you. -- Video Game Voters Network

  • Will people respect a Masters of Science in IT w/software engineering concentration from RPI?

    - by twneale
    Here's my thing: I got my undergraduate degree in political science, then a law degree. Then I figured out that I love programming and I'm pretty good at it too. It's fun and rewarding enough for me that I'd prefer to do it for a living over almost any form of pure law practice. So I'm looking at getting a masters degree to put some weight behind a possible career switch. If I actually want to develop software (web, in particular), would people in programming circles respect a master's of science in IT? Specifically, consider as an example the MS in IT from Rensselaer Polytechnic Institute (with a concentration in software engineering). Here's the home page: http://www.rpi.edu/IT/graduate/masters_program.html In particular, I mean to draw a contrast between IT as specifically contemplated by the RPI masters program (an interdisciplinary tech/business program) and other MS degrees in computer science or software engineering that focus more on the science and technical aspects. I guess I want to make sure that other programmers would respect my credentials and not consider me as different or underqualified based on the connotations of the phrase "IT". I believe RPI has an unimpeachable reputation for hard science, and the program seems excellent, but it still matters to me how people in industry would perceive it.

  • Project Showcase: SaaS Web Apps Hits a Home Run with New SCMS Database

    - by Webgui
    We love seeing projects from start to finish, and we’re happy to share the latest example with you. Who: SaaS Web Apps – they use Software as a Service to create web applications that look and feel like desktop applications. What: SaaS Web Apps needed to build a Sports Contract Management System (SCMS) for one of its customers, Premier Stinson Sports. Why: The SCMS database is used for collecting, analyzing and recording college coach and athletic directors’ employment and contract data. The Challenge: Premier Stinson Sports works with a number of partners, each with its own needs and unique requirements. For example, USA Today uses the system to provide cutting edge news analysis while The National Sports Law Institute of Marquette University Law School uses it to for the latest sports contract data and student analysis. In addition, the system needed to be secure due to the sensitivity of the data; it was essential that the user security and permissions be easily configurable. As always, performance was a key factor, especially with the intense reporting and analytical capabilities for this project. Because of this, most of the processing had to be done on a dedicated server but the project called for the richness and responsiveness of a desktop application. The Solution: To execute the project, SaaS Web Apps used APS.Net-based Visual WebGui from Gizmox, combined with SQL Server 2008 and SQL Reporting Services. This combination resulted in a quick deployment for SaaS Web Apps’ customers. The Result: The completed project gave each partner the scalability and availability of a web application with the performance and security of a desktop application. As an example, USA Today pulls data from this database to give readers the latest sports stats – Salary analysis of 2010 Football Bowl Subdivision Coaches. And here’s a screenshot of the database itself. Great work, SaaS Web Apps!

  • VMware Workstation Error: Cannot find a valid peer process

    - by Robert Claypool
    I am running VMware Workstation 6.1.5 (build-126130) on CentOS 5.3 (Final). One of the guest machines is reporting an error when I try to power on the most recent snapshot. Snapshots further back in the timeline will power on without any problem. Error: Unable to change virtual machine power state: Cannot find a valid peer process to connect to. Apparently I'm not the only one with this problem. Others have been reporting it since at least early 2005. The forums say to delete unused lock files and restart any hung VMware processes (or restart the host machine), which I have done. Still no luck. Any other ideas?

  • low-cost RAID NAS for home use?

    - by gravyface
    Have a noisy, power-hungry Pentium 4 based Ubuntu server that I want to replace with a nice, low-power mini-ITX/Intel Atom-based machine to do my network services (DHCP, DNS, IPSec, Web/mail, FTP, etc.) and am thinking of a (hopefully) equally-low powered NAS using NFS over GbE with at least 1 TB space and a RAID 5 (preferred) or RAID 0 (likely) configuration for redundancy with a couple of spare disks I can swap in as needed down the road. Would I be better off getting a full sized ATX mobo/case and configuring the RAID internally? I really want to keep power consumption down as much as possible as I leave my home server up 24/7.

  • hyper-v fails when attaching more disk to VM. The VM won't start and generates an error

    - by CasperDK
    I'm lost at what to do about this: Hi... System: Windows 2008 R2 Hyper-V farm running with failover cluster with a EVA 4400 as backend. When I attach a new disk to a VM it fails when I try to start it. If I move the VM to another, say node 1, I can add the disk and I can get them to start. If I move the VM back to node 2 where the problem arose and the VM is running, I get an error during live migration and the VM fails back to node1 where it did run... So it's like there is something wrong with Hyper-V on node 2 and not node 1. Also node 3 has the same issue. Restarting the nodes is NOT an option since I will have this problem again at a later time AND because not all the VMs can run on node 1 which means my client company will experience downtime on the VMs not running on node 1. Any fix for this? An update I have missed perhaps? It has been two years... Here are the errors: An error ocurred while attempting to change the state of virtual machine XXX. 'XXX' failed to start.

  • Motherboard wiring

    - by ML
    I am putting a new motherboard in a chenbro chasis and I dont get how to plugin the wires for powerSW resetSW, etc. It is a SuperMicro P4DP6 motherboard. ** I cant post an image yet, but here is a long to the spot on the mobo where this goes: http://andrewslack.info/mobo.png The powerSW lead is a green and white wire. I have the wire for PowerSW in place as the white wire ground and I have tried the reverse even (green to ground). The wire is covering Pin 1 and 2 in the diagram And I press the power button on the machine and nothing happens. It worked before I replaced the motherboard, the 24-pin ATX power leas is connected as well as the 2dn 6-pin optional power. Thoughts?

  • which factors determines the speed of a processor? [closed]

    - by Deb
    I think that clock rate of processor determines the speed of core, in my case it is 1.86GHz. But If I am not wrong, it also determines that how much energy it will consume. If you have more frequency then more power it will consume. I choose Power Saver scheme to increase my battery life, however it reduces my core speed to half of the actual speed. I understand this happens because of SpeedStep, but I don't see any slowdown of my computer. So my problem is why we have such high frequency cores as it uses too much power. We can use low frequency cores. Actually I get confused between the two terms Speed of the processor and its frequency. So how much important is the frequency of core in case of any processor.

  • About HDD enclosure

    - by kmitnick
    hey guys, how r u doin? I have this 3.5" IDE enclosure, and it works great, I mean I love the idea of enclosures ( not the power feeding thing :), btw can't I just insert a chargable battery to feed the power when I am unable to find an electricity block), anyway my question is, when I finish the usage of the enclosure I safely remove it when using Windows or umount when working with Linux, and after that I got confused whether to turn it off or no? when I turn it off, the HDD suddenly stop spinning as if power failure not as when it was an internal and normally shuted down the pc. So is it ok to turn it off the way I've just said??? regards, ~Abed

  • How does one calculate voltages for overclocking?

    - by TardisGuy
    So, all I know is voltage and clock have something to do with each other. Unstable if too low voltage Too high voltage, and too much heat. or higher voltage + lower clock may heat less than that voltage at higher clock. The reason why im asking is because if I can learn how the power vs speed works, Then i might be able to project some kind of thermal curve to find out where my perfect overclock might be (without 50 burn-ins) But, as is apparent im sure. I have no idea what im talking about. If anyone can help me learn more about this; throw me a page, a macro, whathaveyou I will bow before your awesomeness and... Mail you a phantom hand written thank you letter. Some clarification Rev 1 What im trying to learn: is how much power a cpu is using with measurements (Core Voltage) vs (Clock speed) - It would answer the question: Would a 1.4v core @ 4.0Ghz use as much power as a 1.4v core @ 3.0Ghz?

  • Can't Shut Down computer with windows 8 Release Preview

    - by Bram Winda
    I downloaded Release Preview and installed it. I have a problem when I shut down the computer. After I press windows key + I Power Shut Down, a box pops up titled "Winlogon.exe - No Disk. Then under that is the message "There is no disk in the drive. Please insert a disk into Drive G". After hitting the retry button a couple of different times the screen finally goes dark. When I was going to turn it back on, I noticed the Power Button was still list. The only way to do a complete Shutdown is to hold in the power button directly. How do I fix this problem?

  • scheduled chkdsk on Windows 7 blinking the hard disk light every 5 seconds, what can I do?

    - by Jian Lin
    PG&E (the local electricity company) came and took out the old power meters and put in a new ones by brute force and with no advance notice in our neighborhood, so my computer went down in power. So I went to Windows 7's drive C and schedule a Disk Cleanup (chkdsk) on the next boot up. When it boots up, it says A disk check has been scheduled To skip disk checking, press any key within __ second(s). and then after it shows To skip disk checking, press any key within 1 second(s). it just sits there, with no further message. the hard disc light blinks every 5 seconds. So what is to be done now? I certainly don't want to brute force power off again.

  • How to lock screen in linux before hibernating?

    - by Emanuel Ey
    So when i hibernate my laptop the screen doesn't lock automatically. To solve this i've changed /etc/acpi/powerbtn.sh to contain: su - myUsername -c "gnome-screensaver-command -l" sudo pm-hibernate exit 0 When running this file from a command line it works as intended (ie, lock the screen and then hibernate). Unfortunately, when pressing the power button, it still just hibernates without locking the screen -what am I missing? EDIT: I've added the line whoami>>~/Desktop/test.txt to verify which user is executing the /etc/acpi/powerbtn.shscript. When pressing the power button, the file test.txt is created, but is empty. From this i conclude that the script is in fact being called when pressing the power button. What i do not understand is how the output of whoami can be empty...

  • Suspended Laptop Cannot Wake Up - Ubuntu

    - by Zack
    I've got an ASUS G73JH, and whenever I suspend it or hibernate it, it will not wake up. The screen stays backlight but is black. I can't: Awaken it with the keyboard Awaken it with the mouse Soft power-off by pressing the power button I have to hold down the power button and shut it down that way, and this seems a little unreasonable. Is there a place I could look for more detail as to what's causing this? Is there a known quick-fix to this issue?

  • Cables for building a computer

    - by Faken
    I'm looking at building a computer and I have already done a whole bunch of research the topic and I think I know what I'm doing. My question is where do all the cables required for connecting everything come from? I'm pretty sure that the cables required come from their respective components (power connectors from the power supply, assorted cables from the motherboard, ect). However nowhere have I seen it explicitly stated that the cables come with the component I am buying. Just to confirm, if I buy all the components needed for a basic computer (CPU, motherboard, power supply, case, ram, video card, hard drive) from a website, say newegg, will I have all the screws, cables,connectors, and components to put together a working computer or will I need to buy some cables somewhere?

  • Notebook computer battery says: plugged in but not charging with no further information. Is the bat

    - by Jian Lin
    My 1.5 year old Dell Studio 15 notebook computer has a battery and I keep it attached to the notebook but 98% of the time I just plug in the power adapter. Lately when I unplugged the power adapter, the battery was only good for 10 minutes, and a few days ago, when I unplugged the power adapter, the computer simply turned off. When clicking on the battery icon on Win 7, it says "Plugged in, not charging": is the battery dead? Or can Win 7 have any option to not charge the battery? It is a Dell Studio 15, I wonder if in such case, it looks like it can be a manufacture's defect, would Dell replace the battery? (if there was a recall, then they probably would, i think). The notebook is 1.5 year old.

  • While updating the firmware on my parent's WNR3500v1, I bricked it

    - by Matt
    While updating the firmware on my parent's WNR3500v1, I bricked it. Basically, all that happens now is the power light just flashed. I tried pressing the factory reset button for up to a minute with the power on as well as with the power off. To no avail. Is there anything that can be done other than try to RMA it? Googling around, I found nothing promising. I'm wondering if anyone else has any other solution.
