  • Limit a process's relative (not absolute) processor consumption in Linux

    - by BobBanana
    What is the standard way in Linux to enforce a system policy to limit the relative CPU use of a single process? That is, on a quad-core machine, I never want a process to use more than 2 CPUs at once, even if the process creates more threads. I do not want an absolute time limit, just a relative limit so that one task cannot dominate the machine. This is also different than renice, which allows a process to use all the resources but just politely step aside if others need them too. ulimit is the usual resource limiting tool, but it does not allow such CPU restrictions.. it can limit the number of processes per user, or absolute CPU time, not restrict the maximum number of active threads of a single process. I've found a couple of user-level tools, like CPUlimit, but not a system level tool or setting. Does such a standard resource controller exist in Linux (Red Hat Enterprise, if it matters.) If there is such a limit imposed, how would a user identify it?

  • Migrating users and IIS settings from a workgroup win2k3 machine to a new win2k8r2

    - by amber
    I am retiring my old Windows Server 2003 Standard 32bit machine to a new machine with Windows Server 2008 R2 Standard. The two sticking points are migrating user accounts (and there are a lot of them) and IIS settings/websites (again, there are a lot). The new machine has not been provisioned yet. I'm at that point where I'm about install the OS on it. The old machibe is configured with a mirrored set for its OS and data partitions. I have broken the mirror set, replicated all of the data to an external drive, and then rebuilt the mirror set. In short, I have an image of the old machine to play with while safely leaving it up and running. Thanks!

  • Hardware for multipurpose home server

    - by Michael Dmitry Azarkevich
    Hi guys, I'm looking to set up a multipurpose home server and hoped you could help me with the hardware selection. First of all, the services it will provide: Hosting a MySQL database (for training and testing purposes) FTP server Personal Mail Server Home media server So with this in mind I've done some research, and found some viable solutions: A standard PC with the appropriate software (Either second hand or new) A non-solid state mini-ITX system A solid state, fanless mini-ITX system I've also noted the pros and cons of each system: A standard second hand PC with old hardware would be the cheapest option. It could also have lacking processing power, not enough RAM and generally faulty hardware. Also, huge power consumption heat generation and noise levels. A standard new PC would have top-notch hardware and will stay that way for quite some time, so it's a good investment. But again, the main problem is power consumption, heat generation and noise levels. A non-solid state mini-ITX system would have the advantages of lower power consumption, lower cost (as far as I can see) and long lasting hardware. But it will generate noise and heat which will be even worse because of the size. A solid state, fanless mini-ITX system would have all the advantages of a non-solid state mini-ITX but with minimal noise and heat. The main disadvantage is the read\write problems of flash memory. All in all I'm leaning towards a non-solid state mini-ITX because of the read\write issues of flash memory. So, after this overview of what I do know, my questions are: Are all these services even providable from a single server? To my best understanding they are, but then again, I might be wrong. Is any of these solutions viable? If yes, which one is the best for my purposes? If not, what would you suggest? Also, on a more software oriented note: OS wise, I'm planning to run Linux. I'm currently thinking of four options I've been recommended: CentOS, Gentoo, DSL (Damn Small Linux) and LFS (Linux From Scratch). Any thoughts on this? Any other distro you would recomend? Regarding FTP services, I've herd good things about FileZila. Anyone has any experience with that? Do you recommend it? Do you recommend something else? Regarding the Mail service, I know nothing about this except that it exists. Any software you recommend for this task? Home media, same as mail service. Any recommended software? Thank you very much.

  • SSD RAID 5 or 10?

    - by Kyle
    I have a few extra SSD drives (I know its rare but this has actually happened). I figured since I have almost 500 GB in SSD's I might as well replace all of my standard HDD's with them. I currently have a RAID 5 setup and enjoy the the speed and redundancy with 10k RPM drives. Should I bother to put my SSD's in RAID 5? I have not heard of anyone doing this and have no idea how it is going to work out. The loss of space doesn't really bother me since I have a 2 TB NAS with all my media on it. Does anyone have experience with putting solid state drives in a RAID 5. If RAID 5 is a bad idea has anyone had experience with a RAID 10? is it possible to stripe the SSD's and provide redundancy with standard HDD's?

  • Apache: Stealth 404 the admin area until authenticated via basic auth, then allow access

    - by Kzqai
    Given a administrative area with urls like this: wp-admin/ wp-admin/whatever wp-admin/another-page wp-adminsecretlogin/ A standard basic-auth coverage would provide a username and password prompt on all three urls, and return a 403 on all failed auth attempts. This is a pretty obvious signal that something exists there, and thus is an invitation to script/brute force access. I would like to instead, require basic auth everywhere, but when not authenticated, not prompt for username and password, and instead return a 404 not found error for all urls except a wp-adminsecretlogin/ url. At that individual-to-the-site url, basic auth could go through, and unlock the rest of the administrative functionality (though the standard application login would still be necessary). How would I do that via apache .htaccess or .conf directives?

  • Ubuntu + SSL ports + AVAST

    - by jurajvt
    I have an interesting problem with communication via standard SSL ports. Fresh installed Ubuntu 14.04 server + Postfix + Dovecot, SASL authentication provided by Dovecot, self-signed certificate generated trough the Dovecot script mkcert.sh. Redirected ports on ZyWALL USG 200. I can send and receive e-mails from outside with standard ports 25 and 110, but not over 587. I am connecting to my server from machine with Windows 8.1 + VMWare Player + Ubuntu 14.04 Desktop + ssh. On Windows host I have installed Avast! antivirus. When I am trying to telnet from virtual machine to server over 587, it refused connection. But when I turn on Avast! it let me in to message Connected to... Same with nmap. When Avast! is turned on it is show me all SSL ports. When I turned it off, only standard ports appeared. OpenSSL shows me CONNECTED(00000003). But outside virtual machine directly in Windows 8.1 using nmap with zenmap there are not opened SSL ports in both Avast! states. From other external linux machines are problems with touching SSL ports same - refused. I have turned on submission in master.cf and 587 port is correctly listening on 0.0.0.0 in process master.pid which belongs to Postfix. I can telnet, or nmap over port 587 to my domain directly from server. Other ports like 995, 993 are OK on localhost, too. It is true, that I can't send emails via 587 anyway (Avast! turned on/off), but I can see ports opened. It is possible, that I have simply bad certificate and Avast! has right one, so with turned it on I can see opened ports? EDIT: To be more clear, I can't see or using port 587 everywhere from outside (tried Thunderbird, telnet, openssl, nmap, putty, swaks; both from Linux or Windows machines) and that is my problem. It was only by chance that I saw opened ports when Avast! is turned on.

  • upgrading servers, need to keep domain same as before. what are the best practices?

    - by nLL
    Hi, I am upgrading a domain controller/file server from win2003 standard to win2008 r2 standard. We are planing to have a file server and an AD controller. Our old hardware will be scrapped, we want to copy all AD users/computers to new machine and keep current domain name. I never done this before. What are the best practices? Is it better if we get a contractor to do it for us? I guess best way to start is to build new servers, copy data, take old server down and put new server online. My gut says we would need to re-join all computers. Is that correct? Any input appreciated.

  • For web development which is more important - CPU and Graphics card OR Ram and SSD Harddrive?

    - by adam
    Buying a laptop is always hard work and questions about specific models dont age well on forums. A popular dilema (especially with apple macbooks) is whether to spend more for a faster cpu and graphics card but settle for standard ram and hd OR drop down and spend the savings on more ram and a faster harddrive such as a ssd. Im wondering for web development i.e. ide, unit tests, photoshop work and some user testing screen capturing now and again what would provide better performance. ( No games, music production or spielberg standard video editing.) For examples sake the current apple lineup for their 15inch macbookpros. 2.66 cpu i7 4gb ram 5400rpm drive 4gig ram vs 2.4 cpu i5 8gb ram 124gb sdd roughly the same price.

  • Is there a way to import a scheduled task from windows 2003 (.job) to windows 2008 (.xml) ?

    - by Rodrigo
    I had some jobs to be moved from the old production server (windows 2003 server standard) to the new machine (windows 2008 server standard), but the new server is unable to read the old .job format, also the import wizard only imports from .xml job files (same version). Obviously I don't want to rebuild all the jobs by hand, but can't find a tool that makes the process a very little easier. I don't trust in Microsoft for this kind of tools, my previously experiences had been to bad (DTS - SSIS). Any ideas? Thanks in advance.

  • Print to UNC Path Permissions

    - by awilinsk
    I am running Windows Server 2008 (not R2) for a print server and I have a program that needs to write to the UNC path of the network printer. I have found that anyone in the Print Operators group is able to write to the UNC path of the network printer, but standard users are not. I have tried adding the same permissions as the Print Operators group to a user, but when I try to write to the UNC path, I get Access Denied. I cannot add users to the Print Operators group because it gives too many permissions. What permissions do I need to set to allow standard users to print to the UNC path of a network printer?

  • Is it worth having SATA 6GB/s cables? [duplicate]

    - by zyboxenterprises
    This question already has an answer here: Are all SATA cables compatible with SATA 3? 2 answers I've just received some SATA 3 6GB/s cables that I ordered last week, and it struck me how ordinary they look when compared to normal standard SATA cables. My PCI-E SATA3 card is yet to arrive. My question is, would a standard SATA cable have the same transfer speeds as my SATA 3 6GB/s cables? Question is similar to this one, but however it doesn't have an answer. This question isn't asking 'are all SATA cables compatible with SATA 3', it's asking whether SATA 2 and SATA 3 transfer speeds are the same.

  • Oracle Fusion Applications: Changing the Game

    - by kellsey.ruppel(at)oracle.com
    Originally posted in the Oracle Profit Magazine, November 2010 Edition. When the order processing system red-flags a customer's credit status, the IT department doesn't get the customer's call. When a supplier misses a delivery date for a key automotive assembly, it's not the CIO who has to answer for the error. Knowledge workers (known in IT circles as "users") are on the front lines when an exception occurs in an established business process. They're also the ones who study sales trends to decide when to open a new store in an up-and-coming neighborhood, which products are most profitable, how employee skill sets are evolving, and which suppliers are most efficient. In short, knowledge workers are masters of business as unusual. Traditional enterprise resource planning (ERP) systems and other familiar enterprise applications excel at automating, managing, and executing standard business processes. These programs shine when everything goes as planned. Life gets even trickier when a traditional application needs to be extended with a new service or an extra step is added to a business process when new products are brought to market, divisions are merged, or companies are acquired. Monolithic applications often need the IT department to step in and make the necessary adjustments--incurring additional costs and delays. Until now. When Oracle unveiled the much-anticipated family of Oracle Fusion Applications at Oracle OpenWorld in September 2010, knowledge workers in particular had a lot to cheer about. Business users will soon have ready access to analytical information and collaboration tools in the context of what they are working on, so they can make better decisions when problems or opportunities arise. Additionally, the Oracle Fusion Applications platform will make it easy for business users to tweak processes, create new capabilities, and find information, often without the need for IT department assistance and while still following company guidelines. And IT leaders will be happy to hear about new deployment options, guided implementation and setup tools, and cost-saving management capabilities. Just as important, the underlying technologies in Oracle Fusion Applications will allow organizations to choose among their existing investments and next-generation enterprise applications so they can introduce innovations at a pace that makes the most business and financial sense. "Oracle Fusion Applications are architected so you don't have to do rip and replace," says Jim Hayes, managing director of the consulting firm Accenture. "That's very important for creating a business case that will get through the steering committee and be approved by the board. It shows you can drive value and make a difference in the near term." For these and other reasons, analysts and early adopters are calling Oracle Fusion Applications a game changer for enterprise customers. The differences become apparent in three key areas: the way we innovate, work, and adopt technology. Game Changer #1: New Standard for InnovationChange is a constant challenge for most businesses, whether the catalysts are market dynamics, new competition, or the ever-expanding regulatory environment. And, in an ongoing effort to differentiate, business leaders are constantly looking for new ways to do business, serve constituents, and bring new products and services to market. In addition, companies face significant costs to keep their applications up-to-date. For example, when a company adds new suppliers to a procurement system, the IT shop typically has to invest time, effort, and even consulting fees for custom integrations that allow various ERP systems to communicate with each other. Oracle Fusion Applications were built on Web services and a modular SOA foundation to ease customizations and integration activities among all applications--whether from Oracle or another vendor. Interfaces and updates written in ubiquitous Java, rather than a proprietary coding language, allow organizations to tap into existing in-house technical skills rather than seek expensive outside specialists. And with SOA, organizations can extend a feature set or integrate with other SOA environments by combining Web services such as "look up customer" into a new business process managed by the BPEL orchestration engine. Flexibility like this has long-term implications. "Because users capture these changes at a higher metadata layer, not in the application's code, changes and additions are protected even as new versions of Oracle Fusion Applications are released," says Steve Miranda, senior vice president of applications development at Oracle. "This is a much more sustainable approach because you don't incur costly customizations that prevent upgrades and other innovations." And changes are easier to make: if one change is made in the metadata, that change is automatically reflected throughout the application interface, business intelligence, business process, and business logic. Game Changer #2: New Standard for WorkBoosting productivity comes down to doing the basics right: running business processes more efficiently and managing exceptions more effectively, so users can accomplish more in the course of a day or spend more quality time with the most profitable customers. The fastest way to improve process efficiency is to reduce the number of steps it takes to execute common tasks, such as ordering office equipment from an internal procurement system. Oracle Fusion Applications will deliver a complete role-based user experience with business intelligence and collaboration capabilities provided in the context of the work at hand. "We created every Oracle Fusion Applications screen by asking 'What does the user need to know?' 'What does he or she need to do?' and 'Who do they need to work with to get the job done?'" Miranda explains. So when the sales department heads need new laptops, the self-service procurement screen will not only display a list of approved vendors and configurations, but also a running list of reviews by coworkers who recently purchased the various models. Embedded intelligence may also display prevailing delivery lead times based on actual order histories, not the generic shipping dates vendors may quote. The pervasive business intelligence serves many other business activities across all areas of the enterprise. For example, a manager considering whether to promote a direct report can see the person's employee profile, with a salary history, appraisal summaries, and a rundown of skills and training. This approach to business intelligence also has implications for supply chain management. "One of the challenges at Ingersoll Rand is lack of visibility in our supply chain," says Mike Macrie, global director of enterprise applications for global industrial firm Ingersoll Rand. "Oracle Fusion Applications are going to provide the embedded intelligence to give us that visibility and give us the ability to analyze those orders at any point in our supply chain." Oracle Fusion Applications will also create a "role-based user experience" that displays a work list of events that need attention, based on user job function. Role awareness guides users with daily lists of action items and exceptions. So a credit manager may see seven invoices with discounts that are about to expire or 12 suppliers that have been put on hold because credit memos are awaiting approval. Individualization extends to the search capabilities of Oracle Fusion Applications. The platform uses Web-style search screens powered by an Oracle enterprise search engine, with a security framework that filters search results so individuals will only see the internal information they're authorized to access. A further aid to productivity is Oracle Fusion Applications' integration with Web 2.0 collaboration and social networking resources for business environments. Hover-over text will reveal relevant contact information whenever the name of a person appears in an Oracle Fusion Application. Users can connect via an online chat, phone call, or instant message without leaving the main application, reducing the time required for an accounts payable staffer to resolve a mismatch between an invoiced charge and the service record, for example. Addresses of suppliers, customers, or partners will also initiate hover-over text to show contact details and Web-based maps. Finally, Oracle Fusion Applications will promote a new way of working with purpose-driven communities that can bring new efficiencies to everything from cultivating sales leads to managing new projects. As soon as a lead or project materializes, the applications will automatically gather relevant participants into an online community that shares member contact information, schedules, discussion forums, and Wiki pages. "Oracle Fusion Applications will allow us to take it to the next level with embedded Web 2.0 tools and the embedded analytics," says Steve Printz, CIO and vice president, supply chain management, at window-and-door manufacturer Pella. "[This] allows those employees today who are processing transactions to really contribute to the success of the company and become decision-makers." Game Changer #3: New Standard for Technology AdoptionAs IT becomes a dominant component of how businesses run and compete, organizations need to lower the cost of implementing applications and introducing new application features. In the past, rolling out new code often required creating a test bed system, moving beta code to a separate system for user feedback, and--once all the revisions were made--moving version one of the software onto production systems, where business users could finally get the needed new features. Oracle Fusion Applications will use a dedicated setup manager application to streamline this process. First, the setup manager will help scope out the project, querying users about their requirements. "From those questions and answers we determine the steps and the order of those steps that will enable that task," Miranda says. Next, system utilities will assign tasks to owners, track completion status, and monitor the overall status of a programming effort. Oracle Fusion Applications can then recommend Web services that allow users to migrate setup choices and steps across all the various deployments of the application. Those setup capabilities automate the migration from test systems to production systems, as well as between different business units that may be using the same application. "The self-service ability of the setup manager helps business users change setups with very little intervention from the IT team," says Ravi Kumar, vice president at IT services company Infosys. "That to me is a big difference from how we've viewed enterprise applications before." For additional flexibility, organizations will be able to adopt Oracle Fusion Applications modules in either of two modes: a single-instance alternative uses one database for all Oracle Fusion Applications, while a "pillar mode" creates separate databases to underpin each application. This means IT departments running any one of Oracle's applications or even third-party applications can plug Oracle Fusion Applications modules into their environment and see additional business value created on top of their existing systems. And Oracle Fusion Applications offer a hybrid approach to deployment. The applications are all software-as-a-service-ready, so customers can choose on-premises, public or private cloud, or a combination of these to suit their business needs. It's that combination of flexibility and a roadmap for the future that may be the biggest game changer of all. "The Oracle Fusion Applications architecture allows us to migrate our company at a pace that's consistent with our business strategy, whereas before we might have had to do it with a massive upgrade," says Macrie of Ingersoll Rand. "We're looking forward to that architecture to really give us more flexibility in how we migrate over time."

  • Just released: a new SEO extension for the ASP.NET MVC routing engine

    - by efran.cobisi
    Dear users,after several months of hard work, we are proud to announce to the world that Cobisi's new SEO routing engine for ASP.NET MVC has been officially released! We even provide a free edition which comes at no cost, so this is something you can't really miss if you are a serious ASP.NET developer. ;)SEO routes for ASP.NET MVCCobisi SEO Extensions - this is the name of the product - is an advanced tool for software developers that allows to optimize ASP.NET MVC web applications and sites for search engines. It comes with a powerful routing engine, which extends the standard ASP.NET routing module to provide a much more flexible way to define search optimized routes, and a complete set of classes that make customizing the entire routing infrastructure very easy and cool.In its simplest form, defining a route for an MVC action is just a matter of decorating the method with the [Route("...")] attribute and specifying the desired URL. The library will take care of the rest and set up the route accordingly; while coding routes this way, Cobisi SEO Extensions also shows how the final routes will be, without leaving the Visual Studio IDE!Manage MVC routes with easeIn fact, Cobisi SEO Extensions integrates with the Visual Studio IDE to offer a large set of time-saving improvements targeted at ASP.NET developers. A new tool window, for example, allows to easily browse among the routes exposed by your applications, being them standard ASP.NET routes, MVC specific routes or SEO routes. The routes can be easily filtered on the fly, to ease finding the ones you are interested in. Double clicking a SEO route will even open the related ASP.NET MVC controller, at the beginning of the specified action method.In addition to that, Cobisi SEO Extensions allows to easily understand how each SEO route is composed by showing the routing model details directly in the IDE, beneath each MVC action route.Furthermore, Cobisi SEO Extensions helps developers to easily recognize which class is an MVC controller and which methods is an MVC action by drawing a special dashed underline mark under each items of these categories.Developers, developers, developers, ...We are really eager to receive your feedback and suggestions - please feel free to ping us with your comments! Thank you! Cheers! -- Efran Cobisi Cobisi lead developer Microsoft MVP, MCSD, MCAD, MCTS: SQL Server 2005, MCP

  • Time Warp

    - by Jesse
    It’s no secret that daylight savings time can wreak havoc on systems that rely heavily on dates. The system I work on is centered around recording dates and times, so naturally my co-workers and I have seen our fair share of date-related bugs. From time to time, however, we come across something that we haven’t seen before. A few weeks ago the following error message started showing up in our logs: “The supplied DateTime represents an invalid time. For example, when the clock is adjusted forward, any time in the period that is skipped is invalid.” This seemed very cryptic, especially since it was coming from areas of our application that are typically only concerned with capturing date-only (no explicit time component) from the user, like reports that take a “start date” and “end date” parameter. For these types of parameters we just leave off the time component when capturing the date values, so midnight is used as a “placeholder” time. How is midnight an “invalid time”? Globalization Is Hard Over the last couple of years our software has been rolled out to users in several countries outside of the United States, including Brazil. Brazil begins and ends daylight savings time at midnight on pre-determined days of the year. On October 16, 2011 at midnight many areas in Brazil began observing daylight savings time at which time their clocks were set forward one hour. This means that at the instant it became midnight on October 16, it actually became 1:00 AM, so any time between 12:00 AM and 12:59:59 AM never actually happened. Because we store all date values in the database in UTC, always adjust any “local” dates provided by a user to UTC before using them as filters in a query. The error we saw was thrown by .NET when trying to convert the Brazilian local time of 2011-10-16 12:00 AM to UTC since that local time never actually existed. We hadn’t experienced this same issue with any of our US customers because the daylight savings time changes in the US occur at 2:00 AM which doesn’t conflict with our “placeholder” time of midnight. Detecting Invalid Times In .NET you might use code similar to the following for converting a local time to UTC: var localDate = new DateTime(2011, 10, 16); //2011-10-16 @ midnight const string timeZoneId = "E. South America Standard Time"; //Windows system timezone Id for "Brasilia" timezone. var localTimeZone = TimeZoneInfo.FindSystemTimeZoneById(timeZoneId); var convertedDate = TimeZoneInfo.ConvertTimeToUtc(localDate, localTimeZone); The code above throws the “invalid time” exception referenced above. We could try to detect whether or not the local time is invalid with something like this: var localDate = new DateTime(2011, 10, 16); //2011-10-16 @ midnight const string timeZoneId = "E. South America Standard Time"; //Windows system timezone Id for "Brasilia" timezone. var localTimeZone = TimeZoneInfo.FindSystemTimeZoneById(timeZoneId); if (localTimeZone.IsInvalidTime(localDate)) localDate = localDate.AddHours(1); var convertedDate = TimeZoneInfo.ConvertTimeToUtc(localDate, localTimeZone); This code works in this particular scenario, but it hardly seems robust. It also does nothing to address the issue that can arise when dealing with the ambiguous times that fall around the end of daylight savings. When we roll the clocks back an hour they record the same hour on the same day twice in a row. To continue on with our Brazil example, on February 19, 2012 at 12:00 AM, it will immediately become February 18, 2012 at 11:00 PM all over again. In this scenario, how should we interpret February 18, 2011 11:30 PM? Enter Noda Time I heard about Noda Time, the .NET port of the Java library Joda Time, a little while back and filed it away in the back of my mind under the “sounds-like-it-might-be-useful-someday” category.  Let’s see how we might deal with the issue of invalid and ambiguous local times using Noda Time (note that as of this writing the samples below will only work using the latest code available from the Noda Time repo on Google Code. The NuGet package version 0.1.0 published 2011-08-19 will incorrectly report unambiguous times as being ambiguous) : var localDateTime = new LocalDateTime(2011, 10, 16, 0, 0); const string timeZoneId = "Brazil/East"; var timezone = DateTimeZone.ForId(timeZoneId); var localDateTimeMaping = timezone.MapLocalDateTime(localDateTime); ZonedDateTime unambiguousLocalDateTime; switch (localDateTimeMaping.Type) { case ZoneLocalMapping.ResultType.Unambiguous: unambiguousLocalDateTime = localDateTimeMaping.UnambiguousMapping; break; case ZoneLocalMapping.ResultType.Ambiguous: unambiguousLocalDateTime = localDateTimeMaping.EarlierMapping; break; case ZoneLocalMapping.ResultType.Skipped: unambiguousLocalDateTime = new ZonedDateTime( localDateTimeMaping.ZoneIntervalAfterTransition.Start, timezone); break; default: throw new InvalidOperationException(string.Format("Unexpected mapping result type: {0}", localDateTimeMaping.Type)); } var convertedDateTime = unambiguousLocalDateTime.ToInstant().ToDateTimeUtc(); Let’s break this sample down: I’m using the Noda Time ‘LocalDateTime’ object to represent the local date and time. I’ve provided the year, month, day, hour, and minute (zeros for the hour and minute here represent midnight). You can think of a ‘LocalDateTime’ as an “invalidated” date and time; there is no information available about the time zone that this date and time belong to, so Noda Time can’t make any guarantees about its ambiguity. The ‘timeZoneId’ in this sample is different than the ones above. In order to use the .NET TimeZoneInfo class we need to provide Windows time zone ids. Noda Time expects an Olson (tz / zoneinfo) time zone identifier and does not currently offer any means of mapping the Windows time zones to their Olson counterparts, though project owner Jon Skeet has said that some sort of mapping will be publicly accessible at some point in the future. I’m making use of the Noda Time ‘DateTimeZone.MapLocalDateTime’ method to disambiguate the original local date time value. This method returns an instance of the Noda Time object ‘ZoneLocalMapping’ containing information about the provided local date time maps to the provided time zone.  The disambiguated local date and time value will be stored in the ‘unambiguousLocalDateTime’ variable as an instance of the Noda Time ‘ZonedDateTime’ object. An instance of this object represents a completely unambiguous point in time and is comprised of a local date and time, a time zone, and an offset from UTC. Instances of ZonedDateTime can only be created from within the Noda Time assembly (the constructor is ‘internal’) to ensure to callers that each instance represents an unambiguous point in time. The value of the ‘unambiguousLocalDateTime’ might vary depending upon the ‘ResultType’ returned by the ‘MapLocalDateTime’ method. There are three possible outcomes: If the provided local date time is unambiguous in the provided time zone I can immediately set the ‘unambiguousLocalDateTime’ variable from the ‘Unambiguous Mapping’ property of the mapping returned by the ‘MapLocalDateTime’ method. If the provided local date time is ambiguous in the provided time zone (i.e. it falls in an hour that was repeated when moving clocks backward from Daylight Savings to Standard Time), I can use the ‘EarlierMapping’ property to get the earlier of the two possible local dates to define the unambiguous local date and time that I need. I could have also opted to use the ‘LaterMapping’ property in this case, or even returned an error and asked the user to specify the proper choice. The important thing to note here is that as the programmer I’ve been forced to deal with what appears to be an ambiguous date and time. If the provided local date time represents a skipped time (i.e. it falls in an hour that was skipped when moving clocks forward from Standard Time to Daylight Savings Time),  I have access to the time intervals that fell immediately before and immediately after the point in time that caused my date to be skipped. In this case I have opted to disambiguate my local date and time by moving it forward to the beginning of the interval immediately following the skipped period. Again, I could opt to use the end of the interval immediately preceding the skipped period, or raise an error depending on the needs of the application. The point of this code is to convert a local date and time to a UTC date and time for use in a SQL Server database, so the final ‘convertedDate’  variable (typed as a plain old .NET DateTime) has its value set from a Noda Time ‘Instant’. An 'Instant’ represents a number of ticks since 1970-01-01 at midnight (Unix epoch) and can easily be converted to a .NET DateTime in the UTC time zone using the ‘ToDateTimeUtc()’ method. This sample is admittedly contrived and could certainly use some refactoring, but I think it captures the general approach needed to take a local date and time and convert it to UTC with Noda Time. At first glance it might seem that Noda Time makes this “simple” code more complicated and verbose because it forces you to explicitly deal with the local date disambiguation, but I feel that the length and complexity of the Noda Time sample is proportionate to the complexity of the problem. Using TimeZoneInfo leaves you susceptible to overlooking ambiguous and skipped times that could result in run-time errors or (even worse) run-time data corruption in the form of a local date and time being adjusted to UTC incorrectly. I should point out that this research is my first look at Noda Time and I know that I’ve only scratched the surface of its full capabilities. I also think it’s safe to say that it’s still beta software for the time being so I’m not rushing out to use it production systems just yet, but I will definitely be tinkering with it more and keeping an eye on it as it progresses.

  • Why is C++ backward compatibility important / necessary?

    - by Giorgio
    As far as understand it is a well-established opinion within the C++ community that C is an obsolete language that was useful 20 years ago but cannot support many modern good programming practices, or even encourages bad practices; certain features that were typical of C++ (C with classes) during the nineties are also obsolete and considered bad practice in modern C++ (e.g., new and delete should be replaced by smart pointer primitives). In view of this, I often wonder why backward compatibility with C and obsolete C++ features is still considered important: to my knowledge there is no 100% compatibility, but most of C and C++ are contained in C++11 as a subset. Of course, there is a lot of legacy code and libraries (possibly containing templates) that are written using a previous standard of the language and which still need to be maintained or used in connection with new code. Nevertheless, maybe it would still be possible to drop obsolete C and C++ features (e.g. the mentioned new / delete) from a future C++ standard so that it is impossible to use them in new code. In this way, old and dangerous programming practices would be quickly banned from new code, and modern, better programming practices would be enforced by the compiler. Legacy code could still be maintained using separate compilation (having C alongside C++ source files is already a common practice). Developers would have to choose between one compiler supporting the old-style C++ that was common during the nineties and a compiler supporting the modern C++? style (the question mark indicates a future, hypothetical revision). Only mixing the two styles would be forbidden. Would this be a viable strategy for encouraging the adoption of modern C++ practices? Are there conceptual reasons or technical problems (e.g. compiling existing templates) that make such a change undesirable or even impossible? Has such a development been proposed in the C++ community. If there has been some extended discussion on the topic, is there any material on-line?

  • Oracle Coherence & Oracle Service Bus: REST API Integration

    - by Nino Guarnacci
    This post aims to highlight one of the features found in Oracle Coherence which allows it to be easily added and integrated inside a wider variety of projects.  The features in question are the REST API exposed by the Coherence nodes, with which you can interact in the wider mode in memory data grid.Oracle Coherence and Oracle Service Bus are natively integrated through a feature found in the Oracle Service Bus, which allows you to use the coherence grid cache during the configuration phase of a business service. This feature allows you to use an intermediate layer of cache to retrieve the answers from previous invocations of the same service, without necessarily having to invoke the real business service again. Directly from the web console of Oracle Service Bus, you can decide the policies of eviction of the objects / answers and define the discriminating parameters that identify their uniqueness.The coherence REST APIs, however, allow you to integrate both products for other necessities enabling realization of new architectures design.  Consider coherence’s node as a simple service which interoperates through the stardard services and in particular REST (with JSON and XML). Thinking of coherence as a company’s shared service, able to have an implementation of a centralized “map and reduce” which you can access  by a huge variety of protocols (transport and envelopes).An amazing step forward for those who still imagine connectors and code. This type of integration does not require writing custom code or complex implementation to be self-supported. The added value is made unique by the incredible value of both products independently, and still more out of their simple and robust integration.As already mentioned this scenario discovers a hidden new door behind the columns of these two products. The door leads to new ideas and perspectives for enterprise architectures that increasingly wink to next-generation applications: simple and dynamic, perhaps towards the mobile and web 2.0.Below, a small and simple demo useful to demonstrate how easily is to integrate these two products using the Coherence REST API. This demo is also intended to imagine new enterprise architectures using this approach.The idea is to create a centralized system of alerting, fed easily from any company’s application, regardless of the technology with which they were built . Then use a representation standard protocol: RSS, using a service exposed by the service bus; So you can browse and search only the alerts that you are interested on, by category, author, title, date, etc etc.. The steps needed to implement this system are very simple and very few. Here they are listed below and described to be easily replicated within your environment. I would remind you that the demo is only meant to demonstrate how easily is to integrate Oracle Coherence and the Oracle Service Bus, and stimulate your imagination to new technological approaches.1) Install the two products: In this demo used (if necessary, consult the installation guides of 2 products)  - Oracle Service Bus ver. 11.1.1.5.0 http://www.oracle.com/technetwork/middleware/service-bus/downloads/index.html - Oracle Coherence ver. 3.7.1 http://www.oracle.com/technetwork/middleware/coherence/downloads/index.html 2) Because you choose to create a centralized alerting system, we need to define a structure type containing some alerting attributes useful to preserve and organize the information of the various alerts sent by the different applications. Here, then it was built a java class named Alert containing the canonical properties of an alarm information:- Title- Description- System- Time- Severity 3) Therefore, we need to create two configuration files for the coherence node, in order to save the Alert objects within the grid, through the rest/http protocol (more than the native API for Java, C + +, C,. Net). Here are the two minimal configuration files for Coherence:coherence-rest-config.xml resty-server-config.xml This minimum configuration allows me to use a distributed cache named "alerts" that can  also be accessed via http - rest on the host "localhost" over port "8080", objects are of type “oracle.cohsb.Alert”. 4) Below  a simple Java class that represents the type of alert messages: 5) At this point we just need to startup our coherence node, able to listen on http protocol to manage the “alerts” cache, which will receive incoming XML or JSON objects of type Alert. Remember to include in the classpath of the coherence node, the Alert java class and the following coherence libraries and configuration files:  At this point, just run the coherence class node “com.tangosol.net.DefaultCacheServer”advising you to set the following parameters:-Dtangosol.coherence.log.level=9 -Dtangosol.coherence.log=stdout -Dtangosol.coherence.cacheconfig=[PATH_TO_THE_FILE]\resty-server-config.xml 6) Let's create a procedure to test our configuration of Coherence and in order to insert some custom alerts in our cache. The technology with which you want to achieve this functionality is fully not considerable: Javascript, Python, Ruby, Scala, C + +, Java.... Because the protocol to communicate with Coherence is simply HTTP / JSON or XML. For this little demo i choose Java: A method to send/put the alert to the cache: A method to query and view the content of the cache: Finally the main method that execute our methods:  No special library added in the classpath for our class (json struct static defined), when it will be executed, it asks some information such as title, description,... in order to compose and send an alert to the cache and then it will perform an inquiry, to the same cache. At this point, a good exercise at this point, may be to create the same procedure using other technologies, such as a simple html page containing some JavaScript code, and then using Python, Ruby, and so on.7) Now we are ready to start configuring the Oracle Service Bus in order to integrate the two products. First integrate the internal alerting system of Oracle Service Bus with our centralized alerting system based on coherence node. This ensures that by monitoring, or directly from within our Proxy Message Flow, we can throw alerts and save them directly into the Coherence node. To do this I choose to use the jms technology, natively present inside the Oracle Weblogic / Service Bus. Access to the Oracle WebLogic Administration console and create and configure a new JMS connection factory and a new jms destination (queue). Now we should create a new resource of type “alert destination” within our Oracle Service Bus project. The new “alert destination” resource should be configured using the newly created connection factory jms and jms destination. Finally, in order to withdraw the message alert enqueued in our JMS destination and send it to our coherence node, we just need to create a new business service and proxy service within our Oracle Service Bus project.Our business service is responsible for sending a message to our REST service Coherence using as a method action: PUT Finally our proxy service have to collect all messages enqueued on the destination, execute an xquery transformation on those messages  in order to translate them into valid XML / alert objects useful to be sent to our coherence service, through the newly created business service. The message flow pipeline containing the xquery transformation: Incredibly,  we just did a basic first integration between the native alerting system of Oracle Service Bus and our centralized alerting system by simply configuring our coherence node without developing anything.It's time to test it out. To do this I create a proxy service able to generate an alert using our "alert destination", whenever the proxy is invoked. After some invocation to our proxy that generates fake alerts, we could open an Internet browser and type the URL  http://localhost: 8080/alerts/  so we could see what has been inserted within the coherence node. 8) We are ready for the final step.  We would create a new message flow, that can be used to search and display the results in standard mode. To do this I choosen the standard representation of RSS, to display a formatted result on a huge variety of devices such as readers for the iPhone and Android. The inquiry may be defined already at the time of the request able to return only feed / items related to our needs. To do this we need to create a new business service, a new proxy service, and finally a new XQuery Transformation to take care of translating the collection of alerts that will be return from our coherence node in a nicely formatted RSS standard document.So we start right from this resource (xquery), which has the task of transforming a collection of alerts / xml returned from the node coherence in a type well-formatted feed RSS 2.0 our new business service that will search the alerts on our coherence node using the Rest API. And finally, our last resource, the proxy service that will be exposed as an RSS / feeds to various mobile devices and traditional web readers, in which we will intercept any search query, and transform the result returned by the business service in an RSS feed 2.0. The message flow with the transformation phase (Alert TO Feed Items): Finally some little tricks to follow during the routing to the business service, - check for any queries present in the url to require a subset of alerts  - the http header "Accept" to help get an answer XML instead of JSON: In our little demo we also static added some coherence parameters to the request:sort=time:desc;start=0;count=100I would like to get from Coherence that the results will be sorted by date, and starting from 1 up to a maximum of 100.Done!!Just incredible, our centralized alerting system is ready. Inheriting all the qualities and capabilities of the two products involved Oracle Coherence & Oracle Service Bus: - RASP (Reliability, Availability, Scalability, Performance)Now try to use your mobile device, or a normal Internet browser by accessing the RSS just published: Some urls you may test: Search for the last 100 alerts : http://localhost:7001/alarmsSearch for alerts that do not have time set to null (time is not null):http://localhost:7001/alarms?q=time+is+not+nullSearch for alerts that the system property is “Web Browser” (system = ‘Web Browser’):http://localhost:7001/alarms?q=system+%3D+%27Web+Browser%27Search for alerts that the system property is “Web Browser” and the severity property is “Fatal” and the title property contain the word “Javascript”  (system = ‘Web Broser’ and severity = ‘Fatal’ and title like ‘%Javascript%’)http://localhost:8080/alerts?q=system+%3D+%27Web+Browser%27+AND+severity+%3D+%27Fatal%27+AND+title+LIKE+%27%25Javascript%25%27 To compose more complex queries about your need I would suggest you to read the chapter in the coherence documentation inherent the Cohl language (Coherence Query Language) http://download.oracle.com/docs/cd/E24290_01/coh.371/e22837/api_cq.htm .

  • Unity stuck in 2D mode, Nvidia Quadro graphics "unknown", Nvidia-Current active but not in use

    - by Jordan Lund
    I've seen this problem reported under several questions, but I haven't been able to resolve any of it so I thought I'd bring it all in under one umbrella. I started a new job and was given a Dell Precision M6400 laptop with Nvidia Quadro FX 2700M graphics card. It had a previous version of Ubuntu on it, but nobody had any passwords for it so I wiped the drive and did a fresh install of 11.10 from scratch. I didn't do any updates during installation, preferring to do them after boot. Updates ran fine and the system works... except Unity is in 2D mode. System Settings - Additional Drivers shows that Nvidia-Current is active but not in use. System Settings - System Info shows Graphics Driver Unknown, Experience Standard Nvidia X Server Settings is installed and working, re-writing the xorg.conf did nothing. /usr/lib/nux/unity_support_test -p OpenGL vendor string: NVIDIA Corporation OpenGL renderer string: Quadro FX 2700M/PCI/SSE2 OpenGL version string: 3.3.0 NVIDIA 285.05.09 Not software rendered: yes Not blacklisted: yes GLX fbconfig: yes GLX texture from pixmap: yes GL npot or rect textures: yes GL vertex program: yes GL fragment program: yes GL vertex buffer object: yes GL framebuffer object: yes GL version is 1.4+: yes Unity 3D supported: yes One suggestion was to do a sudo apt-get --purge remove nvidia* and that resulted in a scrambled screen on boot and a non-bootable installation. Pressing the Delete key on boot allowed me to access the recovery console and do a sudo apt-get install nvidia-current, which brought me back to a working, bootable system. Another suggestion was to edit /etc/default/grub and change the line reading "GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to read "GRUB_CMDLINE_LINUX_DEFAULT="quiet splash vmalloc=192MB" thus allocating more video RAM. I did that, followed by a sudo update-grub and a re-boot. No change. Created a brand new standard user and logged on with that account, no change.

  • SQL Server 2008 R2 Installation and the Phantom of SQL Server 2005 Express

    - by Davide Mauri
    Today I’ve happy started to install SQL Server 2008R2 on my development machine, which has this software installed Windows Server 2008 R2 Standard SQL Server 2008 SP1 CU5 Visual Studio 2008 SP1 BOL October 2009 AdventuresWorks2008 Databases SR4 Visual Studio 2010 RTM So, all the basic standard stuff. SQL Server 2008 R2 installation went smooth ‘till somewhere in the middle, where the rule engine checks that software pre-requisite are satisfied before starting to copy files. Here I had this @][@@[?!?! error: “The SQL Server 2005 Express Tools are installed. To continue, remove the SQL Server 2005 Express Tools.” Fun enough, I don’t have and I’ve never had SQL Server 2005 Express on my machine. Armed with patience I analyzed the install log here C:\Program Files\Microsoft SQL Server\100\Setup Bootstrap\Log\yyyymmdd_hhmmss\Detail.txt and I’ve found that the rule “Sql2005SsmsExpressFacet” is the one in charge of this check and it look for existance of the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\90\Tools\ShellSEM (on x86) HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Microsoft SQL Server\90\Tools\ShellSEM (on x64) In my registry I’ve found that key existsing, due to the installation of the uber-cool Red-Gate SQL Search. I removed the registry key and here it is! SQL Server 2008 R2 is installing while I’m writing this post. A note to Microsoft: can you please add more detailed information on the setup while such error happens. Just saying “you have SQL Server 2005 Express installed” is not enough. Please show us what the rule look for and why it has failed directly in the Detailed Report, so that we don’t have to spend time to look for the needle in the logs. Thanks! :) PS I did a side-by-side installation with the existing SQL Server 2008 instance. Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

  • Filling in PDF Forms with ASP.NET and iTextSharp

    The Portable Document Format (PDF) is a popular file format for documents. PDF files are a popular document format for two primary reasons: first, because the PDF standard is an open standard, there are many vendors that provide PDF readers across virtually all operating systems, and many proprietary programs, such as Microsoft Word, include a "Save as PDF" option. Consequently, PDFs server as a sort of common currency of exchange. A person writing a document using Microsoft Word for Windows can save the document as a PDF, which can then be read by others whether or not they are using Windows and whether or not they have Microsoft Word installed. Second, PDF files are self-contained. Each PDF file includes its complete text, fonts, images, input fields, and other content. This means that even complicated documents with many images, an intricate layout, and with user interface elements like textboxes and checkboxes can be encapsulated in a single PDF file. Due to their ubiquity and layout capabilities, it's not uncommon for a websites to use PDF technology. For example, when purchasing goods at an online store you may be offered the ability to download an invoice as a PDF file. PDFs also support form fields, which are user interface elements like textboxes, checkboxes, comboboxes, and the like. These form fields can be entered by a user viewing the PDF or, with a bit of code, they can be entered programmatically. This article is the first in a multi-part series that examines how to programmatically work with PDF files from an ASP.NET application using iTextSharp, a .NET open source library for PDF generation. This installment shows how to use iTextSharp to open an existing PDF document with form fields, fill those form fields with user-supplied values, and then save the combined output to a new PDF file.

  • Pivotal Announces JSR-352 Compliance for Spring Batch

    - by reza_rahman
    Pivotal, the company currently funding development of the popular Spring Framework, recently announced JSR 352 (aka Batch Applications for the Java Platform) compliance for the Spring Batch project. More specifically, Spring Batch targets JSR-352 Java SE runtime compatibility rather than Java EE runtime compatibility. If you are surprised that APIs included in Java EE can pass TCKs targeted for Java SE, you should not be. Many other Java EE APIs target compatibility in Java SE environments such as JMS and JPA. You can read about Spring Batch's support for JSR-352 here as well as the Spring configuration to get JSR-352 working in Spring (typically a very low level implementation concern intended to be completely transparent to most JSR-352 users). JSR 352 is one of the few very encouraging cases of major active contribution to the Java EE standard from the Spring development team (the other major effort being Rod Johnson's co-leadership of JSR 330 along with Bob Lee). While IBM's Christopher Vignola led the spec and contributed IBM's years of highly mission critical batch processing experience from products like WebSphere Compute Grid and z/OS batch, the Spring team provided major influences to the API in particular for the chunk processing, listeners, splits and operational interfaces. The GlassFish team's own Mahesh Kannan also contributed, in particular by implementing much of the Java EE integration work for the reference implementation. This was an excellent example of multilateral engineering collaboration through the standards process. For many complex reasons it is not too hard to find evidence of less than amicable interaction between the Spring ecosystem and the Java EE standard over the years if one cares to dig deep enough. In reality most developers see Spring and Java EE as two sides of the same server-side Java coin. At the core Spring and Java EE ecosystems have always shared deep undercurrents of common user bases, bi-directional flows of ideas and perhaps genuine if not begrudging mutual respect. We can all hope for continued strength for both ecosystems and graceful high notes of collaboration via efforts like JSR 352.

  • Why Standards Only Get You So Far

    - by Tim Murphy
    Over the years I have been exposed to a number of standards.  EDI was the first.  More recently it has been the CIECA standard for Insurance and now the embattled document standards of Open XML and ODF. Standards actually came up at the last CAG meeting.  The debate was over how effective they really are.  Even back in the late 80’s to early 90’s people found they had to customize these standards to get any work done.  I even had one vendor about a year ago tell me that they really weren’t standards, they were more of a guideline. The problem is that standards are created either by committee or by companies trying to sell a product.  They never fit all situations.  This is why most of them leave extension points in their definition.  Of course if you use those extension points everyone has to have custom code to know how to consume the new product. Standards increase reliability but they stifle innovation and slow the time to market cycle of products.  In this age of ever shortening windows of opportunity that could mean that a company could lose its competitive advantage. I believe that standards are not only good, but essential.  I also believe that they are not a silver bullet.  People who turn competing standards into a type of holy war are really missing the point.  I think we should make the best standards we can, whether that is for a product so that customers can use API, or by committee so that they cross products.  But they also need to be as feature rich and flexible as possible.  They can’t be just the lowest common denominator since this type of standard will be broken the day it is published.  In the end though, it is the market will vote with their dollars. del.icio.us Tags: Office Open XML,ODF,Standards,EDI

  • Daylight Saving Time Visualized

    - by Jason Fitzpatrick
    When you map out the Daylight Saving Time adjusted sunrise and sunset times over the course of the year, an interesting pattern emerges. Chart designer Germanium writes: I tried to come up with the reason for the daylight saving time change by just looking at the data for sunset and sunrise times. The figure represents sunset and sunrise times thought the year. It shows that the daylight saving time change marked by the lines (DLS) is keeping the sunrise time pretty much constant throughout the whole year, while making the sunset time change a lot. The spread of sunrise times as measured by the standard deviation is 42 minutes, which means that the sunrise time changes within that range the whole year, while the standard deviation for the sunset times is 1:30 hours. Whatever the argument for doing this is, it’s pretty clear that reason is to keep the sunrise time constant. You can read more about the controversial history of Daylight Saving Time here.

  • Unity install removed window borders, and display drivers.

    - by Vivek Sharma
    I installed unity, used for a while. Then i installed gnome-shell, used it for a while. Now decided to switch back to standard. Gnome is not working the way it use to be. I am using T61 with nvidia-latest drivers. Following issues... Window borders are not showing. Installed compiz settings, and re-check window decorations option. I had to re-install nvidia driver, as when I tried to apply normal visual effects, it said no display driver found. Gnome panel is not coming, and mouse pointer is a "cross" than a "arrow". I then opened a terminal and enter gnome-panel. Panel came and window borders came back. Nothing is showing on desktop, and the right click is also not populating the menu. When i loging, an error message saying, docky did not start and it requires compiz to work. After starting gnome-panel from terminal, i went to systempreferencesAppearance. And selected normal visual effects. It activated, i selected keep the settings. Now when i restart or re-login, everything is gone. I have to run gnome-panel manually, and then re-enable visual setting. Ofcourse i can add gnome-panel in startup applications, but i want to know what has installing unity/gnome-shell has done, that these setting are messed up. I manually removed mutter, as Appearance application was showing mutter installed, cant enable effects. What shall i do to get back a standard gnome-desktop back.
