  • Is comparing an OO compiler to a SQL compiler/optimizer valid?

    - by Brad
    I'm now doing a lot of SQL development at my new job where as before I was doing Object Oriented desktop app stuff. I keep running across very large scripts (thousands of lines) and wanting to refactor in some way. I am seeing that SQL is a different sort of beast and it's probably fine to have these big scripts for the most part but while explaining this to me people are also insisting that the whole idea of refactoring is bad. That stuff like the .NET compiler are actually burdened by refactored code and that a big wall of code is more efficient and better design than code designed for reuse, readability and scalability. The other argument is that OO compilers are almost dangerously inefficient and don't have efficient memory management or runs too many CPU instructions compared to older "simpler" compilers and compared to SQL. Are these valid complaints? Even if some compiler like a C compiler is modestly more "efficient" (whatever that means on this high of a level without seeing code) would you want to write applications in C over C# or Java? Is comparing an OO compiler to a SQL compiler/optimizer even valid?

  • How to talk a client out of a Flash website?

    - by bunglestink
    I have recently been doing a bunch of web side projects through word of mouth recommendations only. Although I am much more a of a programmer than a designer by any means, my design skills are not terrible, and do not hate dealing with UI like many programmers. As a result, I find myself lured into a bunch of side projects where aside from a minimal back end for content administration, most of the programming is on front end interfaces (read javascript/css). By far the biggest frustration I have had is convincing clients that they do not want Flash. Aside the fact that I really do not enjoy Flash "development", there are many practical reasons why Flash is not desirable (lack of compatibility across devices, decreased client accessibility, plug-in requirements, increased development time, etc.). Instead of just flat out telling the clients "I will not build you a flash website", I would much rather use tactics to convince/explain to them that this is not what they actually want, ie: meet their requirements any better than standard html/css/js and distract users from their content. What kind of first hand experience do others have with this? How do you explain to someone that javascript/css/AJAX is usually a better option for most websites? Why do people want to use Flash so bad to begin with? This question pertains to clients who do not have any technical reasons for wanting flash, but just want it because they think it makes pretty websites.

  • Taking our Friendships to the next level.

    - by RedAndTheCommunity
    Red Gate have been running the Friends of Red Gate program for years now, and over that time we've built some great relationships with some truly awesome members of the SQL and .NET communities. When I took over the running of the program from Annabel in 2011, I was overwhelmed by the enthusiasm and commitment of our Friends. There were just so many of them, however, that it was hard to make the most of the relationships we had with people, and I wanted to fix that. I decided to survey all our Friends, to find out what they wanted to get out of, and put into, being in the Friends of Red Gate (FoRG) program. From the results of that survey, I identified 30 FoRGs that were really willing and able to go that step further to help Red Gate improve their tools, improve their relationship with the community, and improve the Friends of Red Gate program. Those 30 Friends of Red Gate have been awarded 'FoRG+' status. That means they'll: Have a closer relationship with the product teams, by getting involved in projects Have even more access to the inside track about the tools they're interested in Get the opportunity to come visit us at the Red Gate office and really influence the development of the tools. Plus more, depending on how the individual FoRG+ wants to work with us. This doesn't mean I've forgotten our other Friends; I'm working on ways to improve their experience of the Friends of Red Gate program. I'll write about them in another post. If you're an existing Friend of Red Gate, and you're interested in finding out how to get involved in the FoRG+ program, then I'd love to chat to you. For anyone that's interested in joining the Friend of Red Gate program, take a look at the web page dedicated to the program, and get in touch at [email protected] to be put on the waiting list for our 2013 program.

  • Ranking hit after WP site migration

    - by Ben
    I migrated my site from its old domain over a month ago. I followed WMT completely, including 301 redirects from every existing URL to the new domain, and then submitting a change of address. Traffic continued as normal, but then a few days after submitting the change of address traffic plummeted to about 20-30% of what it was previously. Most of my traffic come from organic search, and I can see that for the keywords I had targeted before and performed well with and am now ranking much much lower for. In some cases for low competition keywords I've only lost a few places, for higher competition terms I have really suffered. This has started to pick up a bit (one of my keywords I have risen from 195 to 100 in the last week), but it seems to be a very slow process. How seamless is this process normally? I was under the impression that this would not affect my rankings too severely, but it has now been a month since the move and recovery seems to be very slow, if at all. Is it likely that I've missed something? The only change is that I have moved what was the home page to be more of a sub-page, and now in its place is a magazine-style home page. I understand that links to the old site will now be pointing to the latter which means that rankings for some keywords attributed to the old home page will take a hit, but even on other pages that seem to fit in exactly the same page structure as the previous site I have seen a drop in rankings. Any help would be greatly appreciated. Thanks!

  • "Don't do programming after a few years of starting career". Is this a fair advice?

    - by Muhammad Yasir
    I am a little experienced developer having approximately 5 years experience in PHP and somewhat less in Java, C# and trying to learn some Python nowadays. Since the start of my career as a programmer I have been told every now and then by fellow programmers that programming is suitable for a few early years of a career (most of them take it as 5 years) and that one must change the direction after it. The reason they present include headaches and pressures associated with programming. They also say that programmers are less social and don't usually like to give time to their families, etc. and especially "Oh come on, you can not do programming your entire life!" I am somewhat confused here and need to ask others about it. If I leave programming then what do I do?! I guess teaching may be a good option in this case, but it will require to first earn a PhD degree perhaps. It may also be noteworthy that in my country (Pakistan) the life of a programmer is not very good in that normally they must give 2-3 extra hours in the office to accomplish urgent programming tasks. I have a sense that situation is somewhat similar in other countries and regions as well. Do you think it is fair advice to change career from programming to something else after spending 5 years in this field? UPDATE Oh wow... I never knew people can have 40+ years of experience in this field. I am both excited and amazed seeing that people are doing it since 1971... That means 15 years before my birth! It is nice to be able to talk to such experienced people, we don't get such a chance here in Pakistan.

  • Which would be a better way to load data via ajax

    - by Mike
    I am using google maps and returning html/lat/long from my MySQL database Currently A user picks a business category e.g; "Video Production". an ajax call is sent to a CodeIgniter controller the Controller then queries the db, and returns the following data via JSON Lat/Long of the marker HTML for the popup window this is approximately 34 rows in the database across two tables per business the ajax call receives this data and then plots the marker along with the html onto the map The data that is returned from the controller is one big json object... This is done for all businesses that exist in the Video Production category (currently approx 40 businesses). As you can see, pulling this data for multiple categories (100s of businesses) can get very very taxing on the server. My question is Would it be more beneficial to modify the process flow as such: a user picks a business category e.g; "Video Production". an ajax call is sent to a CodeIgniter controller the controller then queries the database for the location base information lat/long level (used to change marker icon color) This would be a single row per business with several columns the ajax call receives this data and then plots the marker on the map when the user clicks a marker an ajax call is sent to a CodeIgniter Controller the controller queries the database for the HTML and additional data based on business_id and if not, what are some better suggestions to this problem? In summary this means rather than including the HTML and additional data along for each business, only submitting minimal location information and then re-query for that information when each business marker is clicked. Potential Downsides longer load times when a user clicks a marker icon more code?? more queries to the database

  • How to create per-vertex normals when reusing vertex data?

    - by Chris Smith
    I am displaying a cube using a vertex buffer object (gl.ELEMENT_ARRAY_BUFFER). This allows me to specify vertex indicies, rather than having duplicate vertexes. In the case of displaying a simple cube, this means I only need to have eight vertices total. Opposed to needing three vertices per triangle, times two triangles per face, times six faces. Sound correct so far? My question is, how do I now deal with vertex attribute data such as color, texture coordinates, and normals when reusing vertices using the vertex buffer object? If I am reusing the same vertex data in my indexed vertex buffer, how can I differentiate when vertex X is used as part of the cube's front face versus the cube's left face? In both cases I would like the surface normal and texture coordinates to be different. I understand I could average the surface normal, however I would like to render a cube. Also, this still doesn't work for texture coordinates. Is there a way to save memory using a vertex buffer object while being able to provide different vertex attribute data based on context? (Per-triangle would be idea.) Or should I just duplicate each vertex for each context in which it gets rendered. (So there is a one-to-one mapping between vertex, normal, color, etc.) Note: I'm using OpenGL ES.

  • What is the rationale behind Apache Jena's *everything is an interface if possible* design philosophy?

    - by David Cowden
    If you are familiar with the Java RDF and OWL engine Jena, then you have run across their philosophy that everything should be specified as an interface when possible. This means that a Resource, Statement, RDFNode, Property, and even the RDF Model, etc., are, contrary to what you might first think, Interfaces instead of concrete classes. This leads to the use of Factories quite often. Since you can't instantiate a Property or Model, you must have something else do it for you --the Factory design pattern. My question, then, is, what is the reasoning behind using this pattern as opposed to a traditional class hierarchy system? It is often perfectly viable to use either one. For example, if I want a memory backed Model instead of a database-backed Model I could just instantiate those classes, I don't need ask a Factory to give me one. As an aside, I'm in the process of writing a library for manipulating Pearltrees data, which is exported from their website in the form of an RDF/XML document. As I write this library, I have many options for defining the relationships present in the Peartrees data. What is nice about the Pearltrees data is that it has a very logical class system: A tree is made up of pearls, which can be either Page, Reference, Alias, or Root pearls. My question comes from trying to figure out if I should adopt the Jena philosophy in my library which uses Jena, or if I should disregard it, pick my own design philosophy, and stick with it.

  • Brand New Annotations Support

    - by Ondrej Brejla
    Hi all! Today we would like to introduce you our brand new annotation support for NetBeans 7.2. The first thing which is different is the look of annotations in code completion. As you can see, there is a new annotation icon and an annotation type. Because we have a lot of modules with their own annotations, we differ them in code completion window by their type. We support annotations for: ApiGen (legacy PHPDoc annotations), PHPUnit, Doctrine 2 (ORM and ODM) and Symfony 2. Every annotation can be associated with some context. We recognize four of them: function, class/interface (type), method and field. It means that you will get just proper annotations for your class field as well as your global function. Do you have your own annotations? Or do you simply miss some? There is nothing hard to add it in there. We have a simple UI for adding your custom annotations! It's in Tools -> Options -> PHP -> Annotations. Here you can simply add, edit or delete your annotations. When you try to create new one, all fields are prefilled by some default values. So you really don't have to remember "how to use that crazy freemarker syntax". If you are satisfied with your new annotation, you can see it in a code completion window among other annotations. As you can see it has its own "Custom" type. That's all for today and as usual, please test it and if you find something strange, don't hesitate to file a new issue (component php, subcomponent Editor). Thanks.

  • Podcast Show Notes: Old Habits Die Hard in the New SOA World

    - by OTN ArchBeat
    Like the previous series, the latest OTN ArchBeat Podcast program was also recorded in a hotel room just around the corner from Oracle OpenWorld in San Francisco just a few weeks ago. The gathered experts, all members of the OTN architect community, agreed to participate in an informal roundtable discussion of what's happening in Service Oriented Architecture. As you'll hear, the conversation ranged from the maturity of Service Oriented Architecture technology and tools, to the the lingering and typically self-imposed problems that can prevent organizations from realizing the full potential of SOA, to what SOA means in the era of *aaS, mobile computing, and big data. Hajo Normann, Torsten Winterberg, Ronald van Luttikhuizen, and Guido Schmutz (L-R) Hajo Normann, Torsten Winterberg, Danilo Schmeidel, and Lonneke Dikmans (L-R) The Panelists (Listed alphabetically) Lonneke Dikmans, Managing Partner at Vennster, Oracle ACE Director Ronald van Luttikuhuizen, Managing Partner at Vennster, Oracle ACE Director Hajo Normann, SOA & BPM Lead for ASG at Accenture, Oracle ACE Director Danilo Schmiedel, Solution Architect at Opitz Consulting Guido Schmutz, Technology Manager for SOA/BPM and Architecture Board at Trivadis, Oracle ACE Director Torsten Winterberg, Director of Strategy and Innnovation and head of SOA Competence Center at Opitz Consulting, Oracle ACE Director The Conversation Listen to Part 1: SOA technology and tools are mature, says this panel of experts, but why do some organizations still struggle to take full advantage of industrialized SOA? Listen to Part 2 (Nov 6): Human nature and a lack of trust among stakeholders can thwart successful SOA. Can a marketplace approach and social tools improve the situation? Listen to Part 3 (Nov 13): Do SOA stakeholders recognize the problems caused by poor communication among siloed service development teams?

  • CodeGolf : Find the Unique Paths

    - by st0le
    Here's a pretty simple idea, in this pastebin I've posted some pair of numbers. These represent Nodes of a unidirected connected graph. The input to stdin will be of the form, (they'll be numbers, i'll be using an example here) c d q r a b d e p q so x y means x is connected to y (not viceversa) There are 2 paths in that example. a->b->c->d->e and p->q->r. You need to print all the unique paths from that graph The output should be of the format a->b->c->d->e p->q->r Notes You can assume the numbers are chosen such that one path doesn't intersect the other (one node belongs to one path) The pairs are in random order. They are more than 1 paths, they can be of different lengths. All numbers are less than 1000. If you need more details, please leave a comment. I'll amend as required. Shameless-Plug For those who enjoy Codegolf, please Commit at Area51 for its very own site:) (for those who don't enjoy it, please support it as well, so we'll stay out of your way...)

  • Can web apps allow fast data-typists to "type-ahead"?

    - by user61852
    In some data entry contexts, I've seen data typists, type really fast and know so well the app they use, and have a mechanic quality in their work so that they can "type ahead", ie continue typing and "tab-bing" and "enter-ing" faster than the display updates, so that in many occasions they are typing in the data for the next form before it draws itself. Then when this next entry form appears, their keystrokes fill the text boxes and they continue typing, selecting etc. In contexts like this, this speed is desirable, since this persons are really productive. I think this "type ahead of time" is only possible in desktop apps, but I may be wrong. My question is whether this way of handling the keyboard buffer (which in desktop apps require no extra programming) is achievable in web apps, or is this impossible because of the way web apps work, handle sessions, etc (network latency and the overhead of generating new web pages ) ? Edit: By "type ahead" I mean "keyboard type ahead" (typing faster than the next entry form can load), not suggets-as-you-type-like-google type ahead. Typeahead is a feature of computers and software (and some typewriters) that enables users to continue typing regardless of program or computer operation—the user may type in whatever speed he or she desires, and if the receiving software is busy at the time it will be called to handle this later. Often this means that keystrokes entered will not be displayed on the screen immediately. This programming technique for handling user what is known as a keyboard buffer.

  • How to Hibernate from .NET Apps and How to enable Hibernate in Windows XP

    The usage of Computer desktop or laptop is increased all around the world phenomenally. This link gives you the picture on how power consumption is for various devices we use daily. to reduce the power consumption Hibernate is one of the best way provided by default in Windows Vista or Windows 7. Hibernate feature enables you to close the machine without closing your applications, that means the applications will be restored as they were once we restart the machine. Hibernate feature is not enabled in Windows XP by default. I’ve seen many people that they run (do not switch off) the machines months and months as they do not want to close the windows or applications running in Windows XP. below are the steps to enable Hibernate in Windows XP. Right click on Desktop. Click on properties. Go to screen save tab. Click on power button Select Hibernate tab Check the checkbox “Enabled Hibernate” Apply the settings. Now when you try to shutdown, “Shut down windows” dialog shows “Hibernate” options. Now you can safely close the machine without closing your applications or windows as they will be restored once you on the machine. </SPAN? Some time you might want to provide this future programmatically for the applications you develop for windows. Generally you might want to provide this option in windows applications where process needs huge time. Download managers are the one of the best example. below is the code to do a Hibernate from the .NET code. using System.Windows.Forms;namespace CodeKicks.WinApp.Machine{ public static class MyMachineHelper { public static void DoHibernate() { //Application.SetSuspendState(PowerState.Suspend, true, false); Application.SetSuspendState(PowerState.Hibernate, true, false); } }} span.fullpost {display:none;}

  • Do any CDN services offer multiple urls (or aliases) for your files?

    - by Jakobud
    Lets say a company has multiple commercial web properties that happen to use a lot of the same images on each site. For SEO reasons, the sites must not appear to be related to eachother in any way. This means that the sites can't all link to the same image, even though they all use the same one. Therefore, an image is uploaded to each site and served from each site separately. In order to improve maintainability and latency, lets say the company wanted to use a CDN service. What I'm wondering is, if you upload a file, like an image or something, to a CDN, is there basically one single URL that you access that image at? Or do some (or all) CDN services offer alias URLs so that you can access the same resource from multiple URLs? Example of undesirable situation: Both sites link to the same file URL Site ABC links to <img src="http://123.cdnservice.com/some-path/myimage.jpg"/> Site XYZ links to <img src="http://123.cdnservice.com/some-path/myimage.jpg"/> Example of DESIRABLE situation: Both sites link to the same file via different URLs Site ABC links to <img src="http://123.cdnservice.com/some-path/myimage.jpg"/> Site XYZ links to <img src="http://123.cdnservice.com/some-alias-path/myimage.jpg"/> So in the end, there is only one single file, myimage.jpg on the CDN server, but it is accessible from multiple URLs. Is this possible with CDN services? I know this would make browsers cache the same image twice, but at least it would be better for maintainability. Only one file would ever have to be uploaded.

  • How can I find the shortest path between two subgraphs of a larger graph?

    - by Pops
    I'm working with a weighted, undirected multigraph (loops not permitted; most node connections have multiplicity 1; a few node connections have multiplicity 2). I need to find the shortest path between two subgraphs of this graph that do not overlap with each other. There are no other restrictions on which nodes should be used as start/end points. Edges can be selectively removed from the graph at certain times (as explained in my previous question) so it's possible that for two given subgraphs, there might not be any way to connect them. I'm pretty sure I've heard of an algorithm for this before, but I can't remember what it's called, and my Google searches for strings like "shortest path between subgraphs" haven't helped. Can someone suggest a more efficient way to do this than comparing shortest paths between all nodes in one subgraph with all nodes in the other subgraph? Or at least tell me the name of the algorithm so I can look it up myself? For example, if I have the graph below, the nodes circled in red might be one subgraph and the nodes circled in blue might be another. The edges would all have positive integer weights, although they're not shown in the image. I'd want to find whatever path has the shortest total cost as long as it starts at a red node and ends at a blue node. I believe this means the specific node positions and edge weights cannot be ignored. (This is just an example graph I grabbed off Wikimedia and drew on, not my actual problem.)

  • .NET Demon 1.0 Released

    - by theo.spears
    Today we're officially releasing version 1.0 of .NET Demon, the Visual Studio Extension Alex Davies and I have been working on for the last 6 months. There have been beta versions available for a while, but we have now released the first "official" version and made it available to purchase. If you haven't yet tried the tool, it's all about reducing the time between when you write a line of code and when you are able to try it out so you don't have to wait: Continuous compilation We use spare CPU cycles on your machine to compile your code in the background when you make changes, so assemblies are up to date whenever you want to run them. Some clever logic means we only recompile code which may have been affected by your changes. Continuous save .NET Demon can perform background saving, so you don't lose any work in case of crashes or power failures, and are less likely to forget to commit changed files. Continuous testing (Experimental) The testing tool in .NET Demon watches which code you change in your solution, and automatically reruns tests which are impacted, so you learn about any breaking changes as quickly as possible. It also gives you inline test coverage information inside Visual Studio. Continuous testing is still experimental - it will work fine in many cases, but we know it's not yet perfect. Releasing version 1.0 doesn't mean we're pausing development or pushing out improvements. We will still be regularly providing new versions with improved functionality and fixes for any bugs people come across. Visit the .NET Demon product page to download

  • WARNING Retrying Bulk Insert for file:sqlldr due to Communication Error:256

    - by user702295
    WARNING Retrying Bulk Insert for file:sqlldr due to Communication Error:256 I am running my engine on Linux and am receiving an intermittent message "WARNING Retrying bulk insert for file: sqlldr due to communication Error: 256" The engine seems to have completed successfully, but it is not clear if this error caused some of the forecast to not complete. It is also not clear what caused the error. Generally if you see only the WARNING of it, it means that next retries of the same load request have eventually succeeded and so the run a a whole is not affected. In order to know more about what happens, look for .log/.bad files left in the engines bin directory or possibly a quote of them within the specific engine log that had the issue.  The sqlnet.log file may also have some information about it and perhaps at the database server side there may be some log/alert regarding what happened.  Look at the alert.log. In general it could be that the database server/network was over loaded at the time and somehow the connection was rejected/failed/aborted either due to specific setting on concurrent connections/sessions or inadvertently due to glitch in network/os/hardware. If this repeats and becomes more frequent during the run you should look further into it as mentioned above. You can also track this using either SQL*Trace or java.util.logging.  - Globally enable logging by setting the oracle.jdbc.Trace system property java -Doracle.jdbc.Trace=true - Client Side Tracing: Your SQLNET.ORA file should contain the following lines to produce a client side trace file: trace_level_client = 10 trace_unique_client = on trace_file_client = sqlnet.trc trace_directory_client = <path_to_trace_dir> Server Side Tracing: To enable server side tracing, use the following parameters: trace_level_server = 10 trace_file_server = server.trc trace_directory_server = <path_to_trace_dir> Tracing Levels: The following values can be used for TRACE_LEVEL* parameters:     16 or SUPPORT — WorldWide Customer Support trace information     10 or ADMIN — Administration trace information     4 or USER — User trace information     0 or OFF — no tracing, the default Additional information is readily available via the web.

    Six years ago, I started this SQLAuthority.com blog. There are so many things I want to say today – it is very very emotional. Instead of writing long I am including few images and cartoons. Last month we have also reached 50 Million Total Views on this blog. Here is the screen captured at that time. Click Image to Enlarge In 6 years there are total 2192 days (including 2 leap year day) and my total blog post count is 2300. That means I have been blogging more than 1 blog post every day. Here is the quick glance to all the numbers. Here you can find the list of all the 2300 blog posts. I am very glad to see my many of the friends stay in USA, India, United Kingdom, Canada and Australia in that order. You can see the geographic distribution of the support I receive on the blog from worldwide. On this day I would like to call out one 2 individuals who contribute equally or more in my success. When I started this blog 6 years ago, I was walking alone. After 2 years my wife Nupur joined my journey and 3 years later my daughter Shaivi joined the journey. Here is the example of the common conversation among us almost every day - Shaivi: Daddy, play catch-catch. Nupur: Shaivi, daddy will play with you once he finishes tomorrow’s blog. Shaivi: Daddy, Finish Blog. Okey. I play catch-catch (alone). SQLAuthority Family Well, thank you very much! We all love you!

  • Iphone/Android app – chatroom development – what framework & hosting needs?

    - by MikaelW
    I have some experience regarding IPhone and Android development but I am now struggling to solve a new class of problem: apps that involve a client/server chatroom feature. That is, an app when people can exchange text over the internet, and without having the app to constantly “pull” content from the server. So that problem can’t be solved with a normal php/mysql website, there must be some kind of application running on a server that is able to send message from the server to the phone, rather than having the phone to check for new messages every 10 seconds… So I’m looking for ways to solve the different problems here: What framework should I use on the two sides (phone / server)? It should be some kind of library that doesn’t prevent me to write paid apps. It should also be possible to have the same server for the Iphone and android version of the app. What server / hosting solution do I need with what sort of features, I just have no experience regarding server application that can handle and initiate multiple connections and are hosted on hardware that is always online I tried to find resources online but couldn’t so far, either the libraries had the wrong kind of license/language or I just didn’t understand… Sometimes there were nice tutorial but for different needs such as peer2peer chat over local network… Same with the server and the hosting problem, not sure where to start really, I’m calling for help and I promise I will complete this page with notes about the experience I will get :-) Obviously the ideal would be to find a tutorial I missed that include client code, server code and a free scalable server… That being said, If I see something as good, it probably means that I have eaten the wrong kind of mushroom again… So, failing that, any pointer which might help me toward that quest, would be greatly appreciated. Thanks in advance. Mikael

  • Just Another Web Service (JAWS) vs SOA

    Over the last few years SOA has been a hot topic lending it to be abused by many that have no understanding of the concept. In my opinion, one of the largest issues facing SOA is the lack of understanding and experience implementing SOA by business and IT alike. I just recently deployed a new web services that is called by multiple service clients. Would you call this SOA because it is a web service that can be called by any requesting client? In my opinion, this is not SOA; instead it is Just Another Web Service (JAWS).  Just because a company creates a web service does not mean that they are using SOA, in fact it only means that they are using a web service. SOA is an architectural style that focuses on the design of systems based on the consumer and providers thorough the use of contracts.  With this approach SOA needs to be applied for the top down in order for it to reach its full potential. In the case of the web service, the service is just a small part of the entire system that is reusable and has the flexibility to change. In order for a company in this case to move towards SOA then they need to define business processes that can be shared through the use of reusable software and loose coupling. Once the company’s thought and development process change to address changes in this manner they can start to become more SOA.

  • Oracle SPARC SuperCluster and US DoD Security guidelines

    - by user12611852
    I've worked in the past to help our government customers understand how best to secure Solaris.  For my customer base that means complying with Security Technical Implementation Guides (STIGs) from the Defense Information Systems Agency (DISA).  I recently worked with a team to apply both the Solaris and Oracle 11gR2 database STIGs to a SPARC SuperCluster.  The results have been published in an Oracle White paper. The SPARC SuperCluster is a highly available, high performance platform that incorporates: SPARC T4-4 servers Exadata Storage Servers and software ZFS Storage appliance InfiniBand interconnect Flash Cache  Oracle Solaris 11 Oracle VM for SPARC Oracle Database 11gR2 It is targeted towards large, mission critical database, middleware and general purpose workloads.  Using the Oracle Solution Center we configured a SSC applied DoD security guidance and confirmed functionality and performance of the system.  The white paper reviews our findings and includes a number of security recommendations.  In addition, customers can contact me for the itemized spreadsheets with our detailed STIG reports. Some notes: There is no DISA STIG  documentation for Solaris 11.  Oracle is working to help DISA create one using their new process. As a result, our report follows the Solaris 10 STIG document and applies it to Solaris 11 where applicable. In my conversations over the years with DISA Field Security Office they have repeatedly told me, "The absence of a DISA written STIG should not prevent a product from being used.  Customer may apply vendor or industry security recommendations to receive accreditation." Thanks to the core team: Kevin Rohan, Gary Jensen and Rich Qualls as well as the staff of the Oracle Solution Center and Glenn Brunette for their help in creating the document.

  • Windows Azure Virtual Machines - Make Sure You Follow the Documentation

    - by BuckWoody
    To create a Windows Azure Infrastructure-as-a-Service Virtual Machine you have several options. You can simply select an image from a “Gallery” which includes Windows or Linux operating systems, or even a Windows Server with pre-installed software like SQL Server. One of the advantages to Windows Azure Virtual Machines is that it is stored in a standard Hyper-V format – with the base hard-disk as a VHD. That means you can move a Virtual Machine from on-premises to Windows Azure, and then move it back again. You can even use a simple series of PowerShell scripts to do the move, or automate it with other methods. And this then leads to another very interesting option for deploying systems: you can create a server VHD, configure it with the software you want, and then run the “SYSPREP” process on it. SYSPREP is a Windows utility that essentially strips the identity from a system, and when you re-start that system it asks a few details on what you want to call it and so on. By doing this, you can essentially create your own gallery of systems, either for testing, development servers, demo systems and more. You can learn more about how to do that here: http://msdn.microsoft.com/en-us/library/windowsazure/gg465407.aspx   But there is a small issue you can run into that I wanted to make you aware of. Whenever you deploy a system to Windows Azure Virtual Machines, you must meet certain password complexity requirements. However, when you build the machine locally and SYSPREP it, you might not choose a strong password for the account you use to Remote Desktop to the machine. In that case, you might not be able to reach the system after you deploy it. Once again, the key here is reading through the instructions before you start. Check out the link I showed above, and this link: http://technet.microsoft.com/en-us/library/cc264456.aspx to make sure you understand what you want to deploy.

  • FreeType2 Crash on FT_Init_FreeType

    - by JoeyDewd
    I'm currently trying to learn how to use the FreeType2 library for drawing fonts with OpenGL. However, when I start the program it immediately crashes with the following error: "(Can't correctly start the application (0xc000007b))" Commenting the FT_Init_FreeType removes the error and my game starts just fine. I'm wondering if it's my code or has something to do with loading the dll file. My code: #include "SpaceGame.h" #include <ft2build.h> #include FT_FREETYPE_H //Freetype test FT_Library library; Game::Game(int Width, int Height) { //Freetype FT_Error error = FT_Init_FreeType(&library); if(error) { cout << "Error occured during FT initialisation" << endl; } And my current use of the FreeType2 files. Inside my bin folder (where debug .exe is located) is: freetype6.dll, libfreetype.dll.a, libfreetype-6.dll. In Code::Blocks, I've linked to the lib and include folder of the FreeType 2.3.5.1 version. And included a compiler flag: -lfreetype My program starts perfectly fine if I comment out the FT_Init function which means the includes, and library files should be fine. I can't find a solution to my problem and google isn't helping me so any help would be greatly appreciated.
