  • Revolutionizing Digital Commerce

    - by bwalstra
    The confluence of the Internet, the pace of change in technology, and the demands of the value-conscious consumer are accelerating the evolution of the global digital marketplace at an unprecedented rate. Success in the new digital economy has become inextricably linked with the agility to launch innovative products, services, and new business models efficiently with minimal risk. A major obstacle to agility, and by extension to success in digital commerce, is the fact that by and large information technology (IT) infrastructure is tightly coupled with particular business models. Enterprises, through well intentioned but misconstrued costsaving belief, continue to customize existing infrastructure and create now silos to support new business models. In reality, this approach results in rigid, inflexible business processes and exposes the enterprise to unnecessary risks, higher opportunity costs, and lower profit margins. Oracle, a leading supplier of business solutions to the enterprise, is enabling the business strategies necessary to succeed in the digital economy by offering a modern, open, modular, and functionally comprehensive revenue management solution that decouples IT infrastructure from business models. Enterprises using the Oracle solution are able to focus on core competencies and innovate unimpeded, assuring that business and IT systems will seamlessly adapt to changing conditions of the digital economy.

  • Why would accessing photos over a network be a problem for Digikam?

    - by Shedeki
    Digikam has always worked nicely for me. I recently setup a Synology DiskStation (DS212+) and moved all my pictures to it, keeping them in an encrypted folder. I mount that folder using cifs, as some bug prevents eCryptfs and NFS from working together. This has led Digikam to being incredibly slow. Startup takes a very long time (several minutes for 41779 items, 123.8GB) but worse is how long it takes Digikam to write files. I like using Digikams import feature to copy new images from my camera to the hard drive because it checks for duplicates as well as creating a clear folder structure according to the dates the images were taken. Since I moved to using the network drive Digikam takes about 5 to 10 times as long to import photos than it did before. Saving modified or converted images takes equally long. What I am looking for is a way to help Digikam speed things up or an alternative piece of software (I have never liked Digikam being so very much KDEish…). There are just so many features that only Digikam seems to combine, e.g.: Batch processing. Respects existing folder structure. Does not mess up files for other applications. *.NEF support. Caches thumbnails in a clean way.

  • Were the first assemblers written in machine code?

    - by The111
    I am reading the book The Elements of Computing Systems: Building a Modern Computer from First Principles, which contains projects encompassing the build of a computer from boolean gates all the way to high level applications (in that order). The current project I'm working on is writing an assembler using a high level language of my choice, to translate from Hack assembly code to Hack machine code (Hack is the name of the hardware platform built in the previous chapters). Although the hardware has all been built in a simulator, I have tried to pretend that I am really constructing each level using only the tools available to me at that point in the real process. That said, it got me thinking. Using a high level language to write my assembler is certainly convenient, but for the very first assembler ever written (i.e. in history), wouldn't it need to be written in machine code, since that's all that existed at the time? And a correlated question... how about today? If a brand new CPU architecture comes out, with a brand new instruction set, and a brand new assembly syntax, how would the assembler be constructed? I'm assuming you could still use an existing high level language to generate binaries for the assembler program, since if you know the syntax of both the assembly and machine languages for your new platform, then the task of writing the assembler is really just a text analysis task and is not inherently related to that platform (i.e. needing to be written in that platform's machine language)... which is the very reason I am able to "cheat" while writing my Hack assembler in 2012, and use some preexisting high level language to help me out.

  • Do we have enough time to build an electric car future?

    - by julien.groues
    A recent article from Greenbang has posed the question 'Do we have enough time to build an electric car future?'. The writer discusses that, although the future of transport might lie with electric cars, there is concern regarding whether we'll be able to build the market and infrastructure required to support them, before carbon and oil constraints create difficulties in powering the vehicles. Of course, the increasing use of Electric vehicles (EVs) is going to put excessive pressure on energy grids, as large volumes of electricity will need to be directed to charging points, which in turn must handle fluctuating demand at peak times. EVs are increasing in popularity as a sustainable method of transport to reduce carbon consumption, and electric utilities will have the opportunity, and the challenge, to quickly determine the best methods to fuel these vehicles and accommodate the associated increases in demand for energy. Critically, efficient software is required to provide diagnostic and predictive capabilities related to EV refuelling - for example, anticipated electricity flow will need to be addressed as the number of EVs on the road increases, and electricity will need to be directed to specific areas on-demand as vehicles attempt to recharge en-mass. But a smart grid infrastructure can meet these demands, intelligently. The implementation of a smart grid is not in the distant future, it is an achievable reality for utilities via simple installation of new software and technologies, which can be done incrementally for those facing existing legacy systems or concerned with upfront costs. The smart grid is integral to the monitoring and control of energy use as well as the future-proofing of the energy grid. A smart grid will be critical to meeting the electricity requirements of new EVs and will ensure their successful deployment by providing a reliable foundation for the data handling required to record and manage electricity distribution - from recording and assessing energy usage, to analysing data and sharing information with consumers via green billing. http://www.greenbang.com/do-we-have-enough-time-to-build-an-electric-car-future_14248.html

  • Upgrade from Linux Mint 12 to Kubuntu 12.04?

    - by MountainX
    Is there an "easy" way to "upgrade" my existing Linux Mint 12 install to Kubuntu 12.04 beta 2? I know I could reinstall. Usually I would do a clean install to avoid unexpected issues. But in this case, I don't have time to reconfigure everything from my printers to my installed software, so I am looking for the quick/easy way, but I also want to avoid big risks of an upgrade gone wrong. I'm hoping to just change some repos and run a few commands from the terminal. I don't mind editing a few config files as long as I can find good HOWTOs. But I don't want to be the pioneer (arrows in back). I'm hoping someone has done this before and has a set of steps. For context, I recently installed KDE 4.8 SC onto Kubuntu 11.10 using PPAs. This was on another computer. That wasn't a problem. But I decided to do a fresh install of Kubuntu 12.04 later. I like it well enough that I want to change my other computer from Linux Mint 12 to Kubuntu. (I'm going all-in with KDE. It's now my desktop of choice.) This Linux Mint upgrade will be a move from Gnome and MGSE to KDE, so that will probably complicate things at bit compared to something like upgrading Kubuntu 11.10 to KDE 4.8. References: http://www.psychocats.net/ubuntu/kde Is it safe to install Kubuntu-desktop in 11.10?

  • Is .Net Going to Die As far as Server Apps and Desktop Apps are concerned? [closed]

    - by Graviton
    Possible Duplicate: What does Windows 8 mean for the future of .NET? The Windows 8 preview doesn't mention .Net, and the demo seems to showcase what HTML, CSS and Javascript can do on Windows 8 OS. The impression I get from watching it is that HTML , Javascript is going to figure prominently in Windows 8, even for the traditional windows desktop applications. That, couple with the fact that there is no mentioning of .Net 5 and Visual Studio 2012 or 2013( MS is pretty quick to announce the next generation VS tools) yet, makes me worry that sooner or later, Microsoft will abandon the .Net platform completely. Yes, not just abandoning Silverlight, but the .Net platform in general. Which means that all the desktop apps, server apps you wrote in .Net is going to be obsolete, much like how VB6 apps are now obsolete. Is .Net going to die? Of course you won't find that all .Net apps stop running tomorrow. But will there be a day-- even when at that time Microsoft is alive and kicking-- when .Net apps are looked upon as legacy apps in the way we perceive VB6 apps? Edit: I've changed the wording of the title, so it's not a dupe of existing question. Please take note.

  • StreamInsight Now Available Through Microsoft Update

    - by Roman Schindlauer
    We are pleased to announce that StreamInsight v1.1 is now available for automatic download and install via Microsoft Update globally. In order to enable agile deployment of StreamInsight solutions, you have asked of us a steady cadence of releases with incremental, but highly impactful features and product improvements. Following our StreamInsight 1.0 launch in Spring 2010, we offered StreamInsight 1.1 in Fall 2010 with implicit compatibility and an upgraded setup to support side by side installs. With this setup, your applications will automatically point to the latest runtime, but you still have the choice to point your application back to a 1.0 runtime if you choose to do so. As the next step, in order to enable timely delivery of our releases to you, we are pleased to announce the support for automatic download and install of StreamInsight 1.1 release via Microsoft Update starting this week. If you have a computer: that is subscribed to Microsoft Update (different from Windows Update) has StreamInsight 1.0 installed, and does not yet have StreamInsight 1.1 installed, Microsoft Update will automatically download and install the corresponding StreamInsight 1.1 update side by side with your existing StreamInsight 1.0 installation – across all supported 32-bit and 64-bit Windows operating systems, across 11 supported languages, and across StreamInsight client and server SKUs. This is also supported in WSUS environments, if all your updates are managed from a corporate server (please talk to the WSUS administrator in your enterprise). As an example, if you have SI Client 1.0 DEU and SI Server 1.0 ENU installed on the same computer, Microsoft Update will selectively download and side-by-side install just the SI Client 1.1 DEU and SI Server 1.1 ENU releases. Going forward, Microsoft Update will be our preferred mode of delivery – in addition to support for our download sites, and media based distribution where appropriate. Regards, The StreamInsight Team

  • Is djvubundle available in Ubuntu?

    - by Tim
    The official webpage says Assembling DjVu Images into Multipage Documents The batch compressors distributed as part of the DjVuText and DjVuLayered packages can directly produce multipage DjVu file when fed with multiple input files. The files produced are smaller than if the pages are compressed separately because the compressor can extract and share redundant information accross multiple pages. Individually compressed DjVu pages can be assembled into multipage documents using the free package DjVuMulti. To assemble a bunch of DjVu images into a single BUNDLED document simply type: djvubundle page1.djvu page2.djvu.... pageN.djvu document.djvu To assemble a bunch of DjVu images into an INDIRECT document, type: djvujoin page1.djvu page2.djvu.... pageN.djvu documentdir/index.djvu where documentdir must be an existing directory where all the individual page files will be copied. To disassemble a BUNDLED document into an INDIRECT one, simply say: djvujoin document.djvu documentdir/indexfile.djvu To convert a multipage document from one of the old 2.0 multipage formats, do djvureindex olddocument newdocument The programs djvujoin, and djvubundle supersede the 2.0 programs djvuindex and djvumerge. I couldn't find djvujoin and djvubundle for Ubuntu. djvulibre doesn't have them either. Do I miss something? Thanks.

  • MOSC Bits - Personalized Profile

    - by Irina Donaldson - Moderator -Oracle
    It is a good idea to have a unique profile in MOSC. Your activities there are better recognized and might even become a well known brand! This leads to recognition and trust. My Oracle Support Communities (MOSC)  is a well established platform where experiences are shared. Reputation and trust are the basis for the quality of all communication there. A personalized  profile can help to build up a good reputation. Besides the experience counter, a good name, details about your location and business experience are valuable details. Although a little bit hidden, the profile's avatar can be customized, too. The profile's avatar is an eye catcher and can act as an unique visual representation for  you.  How to add / modify MOSC profile avatar (picture, icon)  ?    Don't look in Edit Profile section. After login, click on  your profile's name on top right.   This lists all public information as part of the Bio section. Select the Activity tab. The Change Avatar link is on same level at far right. A list of predefined symbolic pictures is populated. Choose from the list of existing pictures or try Add Another to upload an image file from your local computer (JPG, PNG, GIF, or BMP only, maximum file size of 2.0 MB). Note: New added images can be used only after running through a review process. Usually after one business day they can be selected for your personal avatar.

  • Visage

    - by Geertjan
    Raj, the Chennai JUG lead, together with others from that JUG, is interested in Visage, the JavaFX script language closely associated with Stephen Chin. He sent me the related lexer and parser and I started by having a look at them in the new version of ANTLRWorks being developed by Sam Harwell (who demonstrated it very effectively during JavaOne): Notice how the lexer and parser are shown in a tree structure, as well as in a cool syntax diagram. Next, I downloaded a bunch of JARs from here, so that packages such as from "com.sun.tools.mjavac" can be used, i.e., these are Visage-specific packages that aren't found anywhere except in the location below: http://code.google.com/p/visage/wiki/GettingStarted It turns out that there's also a Visage NetBeans plugin out there: http://code.google.com/p/visage/source/browse/?repo=netbeans-plugin Rather than recreating everything from scratch, i.e., generating ANTLR Java classes from the lexer and parser, I copied a lot of stuff from the site above and now a file Raj sent me looks as follows, i.e., basic syntax coloring is shown: For anyone wanting to seriously support Visage in NetBeans IDE, I recommend downloading the existing Visage NetBeans plugin above, rather than creating everything yourself from scratch, and then figuring out how to use that code in some way, i.e., add the JARs I pointed to above, and work on its build.xml file, which could be frustrating in the beginning, but there's no point in recreating everything if everything already exists.

  • Turn-based JRPG battle system architecture resources

    - by BenoitRen
    The past months I've been busy programming a 2D JRPG (Japanese-style RPG) in C++ using the SDL library. The exploration mode is more or less done. Now I'm tackling the battle mode. I have been unable to find any resources about how a classic turn-based JRPG battle system is structured. All I find are discussions about damage formula. I've tried googling, searching gamedev.net's message board, and crawling through C++-related questions here on Stack Exchange. I've also tried reading source code of existing open source RPGs, but without a guide of some sort it's like trying to find a needle in a haystack. I'm not looking for a set of rules like D&D or anything similar. I'm talking purely about code and object structure design. A battle system asks the player for input using menus. Next the battle turn is executed as the heroes and the enemies execute their actions. Can anyone point me in the right direction? Thanks in advance.

  • Dirt Cheap Bi-Directional Antenna Wirelessly Extends Your LAN

    - by Jason Fitzpatrick
    If you’re looking for an effective way to link remote LANs without the hassle of laying cable, this DIY bi-directional antenna is a quick (and cheap) method for bringing internet access to outbuildings and other locations. Tinker Danilo Larizza needed to share internet access between apartments that are relatively close together but not hardwired–ruling out simply sharing the access via existing LAN infrastructure. His solution combines a simple scrap wire antenna array mounted inside a plastic food bin (seen here with the cover removed to show the antenna) and some coaxial cable to link the antenna to two routers. Our favorite part about his build is that he constructed the pair to establish if the antenna setup would even work in his location and intended to buy commercial antennas if it did; his Tupperware models worked so well, however, they’re now the permanent solution.

  • OUM is Flexible and Scalable

    - by user535886
    Flexible and Scalable Traditionally, projects have been focused on satisfying the contents of a requirements document or rigorously conforming to an existing set of work products. Often, especially where iterative and incremental techniques have not been employed, these requirements may be inaccurate, the previous deliverables may be flawed, or the business needs may have changed since the start of the project. Fitness for business purpose, derived from the Dynamic Systems Development Method (DSDM) framework, refers to the focus of delivering necessary functionality within a required timebox. The solution can be more rigorously engineered later, if such an approach is acceptable. Our collective experience shows that applying fit-for-purpose criteria, rather than tight adherence to requirements specifications, results in an information system that more closely meets the needs of the business. In OUM, this principle is extended to refer to the execution of the method processes themselves. Project managers and practitioners are encouraged to scale OUM to be fit-for-purpose for a given situation. It is rarely appropriate to execute every activity within OUM. OUM provides guidance for determining the core set of activities to be executed, the level of detail targeted in those activities and their associated tasks, and the frequency and type of end user deliverables. The project workplan should be developed from this core. The plan should then be scaled up, rather than tailored down, to the level of discipline appropriate to the identified risks and requirements. Even at the task level, models and work products should be completed only to the level of detail required for them to be fit-for-purpose within the current iteration or, at the project level, to suit the business needs of the enterprise and to meet the contractual obligations that govern the project. OUM provides well defined templates for many of its tasks. Use of these templates is optional as determined by the context of the project. Work products can easily be a model in a repository, a prototype, a checklist, a set of application code, or, in situations where a high degree of agility is warranted, simply the tacit knowledge contained in the brain of an analyst or practitioner. For further reading on agility, see Balancing Agility and Discipline: A guide fro the Perplexed.

  • SubMain Ghost Doc Pro with SpellChecking

    - by TATWORTH
    SubMain have announced at http://community.submain.com/forums/2/1556/ShowThread.aspx#1556 that the next version of GhostDoc will include a VS2005/VS2008/VS2010 compatible spell checker. This replaces their existing spellchecker (http://submain.com/products/codespell.aspx)  which is being discontinued. If you buy GhostDoc Pro now (I urge you to as it helps tremendously in documenting both C# and VB.NET code) , be sure to include Licence Protection as it means you will get the next version that includes the spell-checker free! Why is a spell checker important? By spell checking all your comments, you will make your documentation much easier to read. This means that instead of you being distracted by typographic errors, your mind will be free to see errors in what has been written. Remember the next person that has to struggle to read your code could well be yourself! So be kind to your self. Do the following: Document whole source files in VB.NET of C# with GhostDoc Pro Run Stylecop and fix the issues it uncovers. Run the spellchecker (when it is available) Add remarks where necessary Specify in the project to produce XML documentation Compile the XML using Sandcastle to help files Review the help files and ask yourself if the explanations are sufficient.

    This question already has an answer here: Methodology for Documenting Existing Code Base 6 answers When do you start documenting the code? 13 answers Where should a programmer explain the extended logic behind the code? 5 answers I have been in this problem for long time and I want to know how it's done in real / big companies project? Suppose I have the project to build a website. Now I divide the project into sub tasks and do it. But you know that suppose I have task1 in hand like export the page to pdf. Now I spend 3 days to do that , came across various problems, many Stack Overflow questions and in the end I solve it. Now 4 months after someone told me that there is some error in the code. Now by that I completely forgot about (60%) of how I did it and why I do this way. I document the code but I can't write the whole story of that in the code. Then I have to spend much time on code to find what was the problem so that I added this line etc. I want to know that is there any way that i can log steps in completing the project. So that I can see how I end up with code, what errors I got, what questions I asked on SO and etc. How people do it in real time? Which software to use? I know in our project management software called JIRA we have tasks but that does not cover what steps I took to solve that tasks. What is the best way so that when I look back at my 2 year old project, I know how I solve particular task?

  • How to create an extensible rope in Box2D?

    - by Thomas
    Let's say I'm trying to create a ninja lowering himself down a rope, or pulling himself back up, all whilst he might be swinging from side to side or hit by objects. Basically like http://ninja.frozenfractal.com/ but with Box2D instead of hacky JavaScript. Ideally I would like to use a rope joint in Box2D that allows me to change the length after construction. The standard Box2D RopeJoint doesn't offer that functionality. I've considered a PulleyJoint, connecting the other end of the "pulley" to an invisible kinematic body that I can control to change the length, but PulleyJoint is more like a rod than a rope: it constrains maximum length, but unlike RopeJoint it constrains the minimum as well. Re-creating a RopeJoint every frame using a new length is rather inefficient, and I'm not even sure it would work properly in the simulation. I could create a "chain" of bodies connected by RotationJoints but that is also less efficient, and less robust. I also wouldn't be able to change the length arbitrarily, but only by adding and removing a whole number of links, and it's not obvious how I would connect the remainder without violating existing joints. This sounds like something that should be straightforward to do. Am I overlooking something?

  • Removing 301 redirect from site root

    - by Jon Clements
    I'm having a look at a friends website (a fairly old PHP based one) which they've been advised needs re-structuring. The key points being: URLs should be lower case and more "friendly". The root of the domain should be not be re-directed. The first point I'm happy with (and the URLs needed tidying up anyway) and have a draft plan of action, however the second is baffling me as to not only the best way to do it, but also whether it should be done. Currently http://www.example.com/ is redirected to http://www.example.com/some-link-with-keywords/ using the follow index.php in the root of the Apache2 instance. <?php $nextpage = "some-link-with-keywords/"; header( "HTTP/1.1 301 Moved Permanently" ); header( "Status: 301 Moved Permanently" ); header("Location: $nextpage"); exit(0); // This is Optional but suggested, to avoid any accidental output ?> As far as I'm aware, this has been the case for around three years -- and I'm sorely tempted to advise to not worry about it. It would appear taking off the 301 could: Potentially affect page ranking (as the 'homepage' would disappear - although it couldn't disappear because of the next point...) Introduce maintainance issues as existing users would still have the re-directed page in their cache Following the above, introduce duplicate content Confuse Google/other SE's as to what the homepage actually is now I may be over-analysing this but I have a feeling it's not as simple as removing the 301 from the root, and 301'ing the previous target to the root... Any suggestions (including it's not worth it) are sincerely appreciated.

  • Setting Gmail as mail server

    - by Tim S.
    I’m in a slightly weird situation right now, and I don’t have sufficient knowledge to sort this myself without truly understand what I’m doing. Yesterday, I’ve registered a domain (.com) and ordered a VPS, attached to that domain. Chances are I may receive mail on my .com address to confirm the domain. Unfortunately, that domain is nothing, but an empty domain. Currently, there’s no mailserver that fetches my mail. Because I don’t have a mailserver available, I (temporarily) want to use Gmail. I prefer to add it to my existing, personal address, but I’m okay with creating a new account as well. I just want to read possible incoming mails. I’ve tried to set MX records to What do I need to do to get mail to a Gmail address? PS. I’m aware of Google, NSA, etc. PPS. I just want to receive mail. I don’t care if I can’t send via my domain. PPS. Detailed steps would be greatly appreciated, I’m a noob.

  • Pre game loading time vs. in game loading time

    - by Keeper
    I'm developing a game in which a random maze is included. There are some AI creatures, lurking the maze. And I want them to go in some path according to the mazes shape. Now there are two possibilities for me to implement that, the first way (which I used) is by calculating several wanted lurking paths once the maze is created. The second, is by calculating a path once needed to be calculated, when a creature starts lurking it. My main concern is loading times. If I calculate many paths at the creating of the maze, the pre loading time is a bit long, so I thought about calculating them when needed. At the moment the game is not 'heavy' so calculating paths in mid game is not noticeable, but I'm afraid it will once it will get more complicated. Any suggestions, comments, opinions, will be of help. Edit: As for now, let p be the number of pre-calculated paths, a creatures has the probability of 1/p to take a new path (which means a path calculation) instead of an existing one. A creature does not start its patrol until the path is fully calculated of course, so no need to worry about him getting killed in the process.

  • Problem connecting to isp server using xl2tpd as client. Ubuntu server 13.04

    - by Deon Pretorius
    I have followed guides found on google and ubuntu support pages and can get xl2tpd connection up but only under the following conditions: 1 - ADSL model must be configured and connected to the ISP or 2 - ADSL modem in bridge mode I must have an existing PPPoe connection established. If neither of the above are active xl2tpd wont trigger pppd and connect to the isp and thus tunnel connection fails to connect to the L2TP server of the ISP. Am I doing something wrong; /etc/ppp/options.l2tpd.axxess ipcp-accept-local ipcp-accept-remote refuse-eap refuse-chap require-pap noccp noauth idle 1800 mtu 1200 mru 1200 defaultroute usepeerdns debug lock connect-delay 5000 name (name used for ppp connection) /etc/ppp/pap-secrets # * password (name used for ppp connection as above) * (ppp password supplied by isp) /etc/xl2tpd/xl2tpd.conf [global] ; Global parameters: auth file = /etc/xl2tpd/l2tp-secrets ; * Where our challenge secrets are access control = yes ; * Refuse connections without IP match debug tunnel = yes [lac axxess] lns = 196.30.121.50 ; * Who is our LNS? redial = yes ; * Redial if disconnected? redial timeout = 5 ; * Wait n seconds between redials max redials = 5 ; * Give up after n consecutive failures hidden bit = yes ; * User hidden AVP's? length bit = yes ; * Use length bit in payload? require pap = yes ; * Require PAP auth. by peer require chap = no ; * Require CHAP auth. by peer refuse chap = yes ; * Refuse CHAP authentication require authentication = yes ; * Require peer to authenticate name = BLA85003@axxess ; * Report this as our hostname ppp debug = yes ; * Turn on PPP debugging pppoptfile = /etc/ppp/options.l2tpd.axxess ; * ppp options file for this lac /etc/xl2tpd/l2tp-secrets # Secrets for authenticating l2tp tunnels # us them secret # * marko blah2 # zeus marko blah # * * interop * vzb_l2tp (*** secret supplied by isp) ^ isp server host name Any help will be greatly appreciated

  • NHibernate Tools: Visual NHibernate

    - by Ricardo Peres
    You probably know that I’m a big fan of Slyce Software’s Visual NHibernate. To me, it is the best tool for generating your entities and mappings from an existing database (it also allows you to go the other way, but I honestly have never used it that way). What I like most about it: Great support: folks at Slyce always listen to your suggestions, give you feedback in a timely manner, and I was even lucky enough to have some of my suggestions implemented! The templating engine, which is very powerful, and more user-friendly than, for example, MyGeneration’s; one of the included templates is Sharp Architecture; Advanced model validations: it even warns you about having lazy properties declared in non-lazy entities; Integration with NHibernate Validator and generation of validation rules automatically based on the database, or on user-defined model settings; The designer: they opted for not displaying all entities in a single screen, which I think was a good decision; has support for all inheritance strategies (table per class hierarchy, table per class, table per concrete class); Generation of FluentNHibernate mappings as well as hbm.xml. I could name others, but… why don’t you see for yourself? There is a demo version available for downloading. By the way, I am in no way related to Slyce, I just happen to like their software!

  • Do you store mysql exports in your version control tool for reverting to in event of error?

    - by Rob
    We run an internal web server with in-house software to run a manufacturing line. When new product features are to be added, either or both of the following occur: changes to the in-house server software may be required to support these - these are for significant changes in functionality, being code drive. changes to the MySQL database for new entries for the part numbers, these are for smaller changes, configurations, changes to already existing values and parameters -- such changes don't require code changes. Ideally we'd want our changes to be here rather than in item 1. Item 1 is version controlled in Subversion, so previous revisions can be referred to for rolling back to in the event of problems introduced in the latest revision. But what about changes to the MySQL database? We have quality processes to ensure that such changes are error-free but there is always a chance that errors can pass through, e.g. mistake in data entry or faults with the code that uses the MySQL corrupting the database etc. We have a automated backup every 6 hours but what if we want more manual defined checkpoints in between these intervals, we could use the same backup system but I wondered if folks here used other methods to store previous states of databases, e.g. exporting the database as a plain text SQL dump -- at least with this method it would be possible to see diffs e.g. in Beyond Compare for trouble shooting. Thoughts?
