• Heading Out to Oracle Open World

  - by rickramsey

  In case you haven't figured it out by now, Oracle reserves an awful lot of announcements for Oracle Open World. As a result, the show is always a lot of fun for geeks. What will the Oracle Solaris team have to say? Will the Oracle Linux team have any surprises? And what about Oracle hardware? For my part, I'll be one of the lizards at the OTN Lounge with the OTN crew, handing out t-shirts to system admins and developers, or anyone who is willing to impersonate one. I understand, not everyone can have the raw animal magnetism of a sysadmin, or the debonair sophistication of a C++ developer, so some of you have no choice but to pretend. I won't judge. I'll also be doing video interviews of as many techie people as I can corner. I've got more than 30 interviews already scheduled. Most of them will be 3-5 minutes long. I'll be asking our best technical minds what's cool about their latest technologies and what impact it will have on system admins or system developers. I'll be posting those videos here: Find OTN Systems Videos from Oracle Open World Here! We've got some great topics in mind. A dummies guide to hardware-assisted cryptography with Glenn Brunette. ZFS deduplication. The momentum building around Oracle Solaris 11, with Lynn Rohrer, plus conversations with partners who have deployed Oracle Solaris 11. Migrating to Oracle Database with SQL Developer. The whole database cloud thing. Oracle VM and, of course, Oracle Linux. So even if you can't be part of the fun, keep an eye out for the videos on our YouTube channel. - Rick Website Newsletter Facebook Twitter

• Would You Swim Laps in Lake Baikal?

  - by rickramsey

  source This is the lake where Yuli Vasiliev's countrymen swim laps. Yuli is one of my favorite OTN writers not just because he really knows his stuff. Not just because his writing is clear and accurate. And not just because his English is better than the English of most native speakers. Yo, those are all good reasons. But it's the Lake Baikal thing. Yuli recently wrote two wicked good how-to's about Oracle VM Templates. You should read them. You might gain a gram of Yuli's respect. Two grams, if you can head butt icebergs while you swim. How to Use Oracle VM Templates How to prepare an Oracle VM environment to use Oracle VM Templates, how to obtain a template, and how to deploy the template to your Oracle VM environment. Also how to create a virtual machine based on that template and how you can clone the template and change the clone's configuration. How to Use Oracle VM VirtualBox Templates How to use Oracle VM VirtualBox Templates in Oracle VM VirtualBox. Similar to the article above, but it describes how to download, install, and configure the templates within Oracle VM VirtualBox, instead of on bare metal.

• Is it unethical to sell the award of a competition? [closed]

  - by Ahmet Yildirim

  This summer, i won a competition held by microsoft & nokia... Winners from each uni. received an high-end smartphone... Knowing that particular "high-end smartphone" had not much user to develop for, as soon as i receive it, i put an ad on a ebay-like site to sell it. Eventually i exchanged it with a tablet which had high developer demand & many many users to develop for , so i could make money by developing for it. I also email microsoft asking, when something technical goes wrong with the device , can i get it fixed by warranty. Which i never received a respond. Later on, after a while... I got some feedback from a connection i have from nokia, regarding sale of the device & asking for the warranty.. He says and i quote : " They say, they werent happy that you sold the device and got offended that you asked for warranty. You should not expect anything at all from microsoft or nokia in the future. " I was like what the frak, they didnt gave it to me as a gift, i won it in a competition as an award , it is my right to do whatever i want. How ethical is that , they dont respond to my email directly? Is it unethical to sell a gadget you won in a competition? Is it unethical to ask for warranty on award?

• Mono is frequently used to say "Yes, .NET is cross-platform". How valid is that claim?

  - by Thorbjørn Ravn Andersen

  In What would you choose for your project between .NET and Java at this point in time? I say that I would consider the "Will you always deploy to Windows?" the single most important (EDIT: technical) decision to make up front in a new web project, and if the answer is "no", I would recommend Java instead of .NET. A very common counter-argument is that "If we ever want to run on Linux/OS X/Whatever, we'll just run Mono", which is a very compelling argument on the surface, but I don't agree for several reasons. OpenJDK and all the vendor supplied JVM's have passed the official Sun TCK ensuring things work correctly. I am not aware of Mono passing a Microsoft TCK. Mono trails the .NET releases. What .NET-level is currently fully supported? Does all GUI elements (WinForms?) work correctly in Mono? Businesses may not want to depend on Open Source frameworks as the official plan B. I am aware that with the new governance of Java by Oracle, the future is unsafe, but e.g. IBM provides JDK's for many platforms, including Linux. They are just not open sourced. So, under which circumstances is Mono a valid business strategy for .NET-applications? Edit: Mark H summarized it as: "If the claim is that "I have a windows application written in .NET, it should run on mono", then not, it's not a valid claim - but Mono has made efforts to make porting such applications simpler.".

• Modelling work-flow plus interaction with a database - quick and accessible options

  - by cjmUK

  I'm wanting to model a (proposed) manufacturing line, with specific emphasis on interaction with a traceability database. That is, various process engineers have already mapped the manufacturing process - I'm only interested in the various stations along the line that have to talk to the DB. The intended audience is a mixture of project managers, engineers and IT people - the purpose is to identify: points at which the line interacts with the DB (perhaps going so far as indicating the Store Procs called at each point, perhaps even which parameters are passed.) the communication source (PC/Handheld device/PLC) the communication medium (wireless/fibre/copper) control flow (if leak test fails, unit is diverted to repair station) Basically, the model will be used as a focus different groups on outstanding tasks; for example, I'm interested in the DB and any front-end app needed, process engineers need to be thinking about the workflow and liaising with the PLC suppliers, the other IT guys need to make sure we have the hardware and comms in place. Obviously I could just improvise in Visio, but I was wondering if there was a particular modelling technique that might particularly suit my needs or my audience. I'm thinking of a visual model with supporting documentation (as little as possible, as much as is necessary). Clearly, I don't want something that will take me ages to (effectively) learn, nor one that will alienate non-technical members of the project team. So far I've had brief looks at BPMN, EPC Diagrams, standard Flow Diagrams... and I've forgotten most of what I used to know about UML... And I'm not against picking and mixing... as long as it is quick, clear and effective. Conclusion: In the end, I opted for a quasi-workflow/dataflow diagram. I mapped out the parts of the manufacturing process that interact with the traceability DB, and indicated in a significantly-simplified form, the data flows and DB activity. Alongside which, I have a supporting document which outlines each process, the data being transacted for each process (a 'data dictionary' of sorts) and details of hardware and connectivity required. I can't decide whether is a product of genius or a crime against established software development practices, but I do think that is will hit the mark for this particular audience.

• Learning Programming during the job?

  - by Hossein

  Introduction: I have read and heard advice, about learning programming by accepting programming projects. I need real assistance to understand this, because: Problem: Although, it would seem to me that one would gain much more technical knowledge by doing, real world projects, if one doesn't know much about a technology, it would add much more risk to the actual delivery of the final product! Even the smallest of real world projects could be too much for a newbie. There is a contradiction here: You need to know the job to do it! and It's recommended to do the job, in order to learn it! Question: Any personal experiences in this case would be very pleasant to know while describing: How new was the subject to you? didn't have a clue at all? Or, did you have experience with similar technologies? Was it a solo project or were you in a team? If team, then did others help you with learning it? Did it work as expected? Did you deliver on time? Do you recommend this approach to others as well?

• Which opcodes are faster at the CPU level?

  - by Geotarget

  In every programming language there are sets of opcodes that are recommended over others. I've tried to list them here, in order of speed. Bitwise Integer Addition / Subtraction Integer Multiplication / Division Comparison Control flow Float Addition / Subtraction Float Multiplication / Division Where you need high-performance code, C++ can be hand optimized in assembly, to use SIMD instructions or more efficient control flow, data types, etc. So I'm trying to understand if the data type (int32 / float32 / float64) or the operation used (*, +, &) affects performance at the CPU level. Is a single multiply slower on the CPU than an addition? In MCU theory you learn that speed of opcodes is determined by the number of CPU cycles it takes to execute. So does it mean that multiply takes 4 cycles and add takes 2? Exactly what are the speed characteristics of the basic math and control flow opcodes? If two opcodes take the same number of cycles to execute, then both can be used interchangeably without any performance gain / loss? Any other technical details you can share regarding x86 CPU performance is appreciated

• What reasons are there to reduce the max-age of a logo to just 8 days? [closed]

  - by callum

  Most websites set max-age=31536000 (1 year) on the Cache-control headers of static assets such as logo images. Examples: YouTube Yahoo Twitter BBC But there is a notable exception: Google's logo has max-age=691200 (8 days). I've checked the headers on the Google logo in the past, and it definitely used to be 1 year. (Also, it used to be part of a sprite, and now it is a standalone logo image, but that's probably another question...) What could be valid technical reasons why they would want to reduce its cache lifetime to just 8 days? Google's homepage is one of the most carefully optimised pages in the world, so I imagine there's a good reason. Edit: Please make sure you understand these points before answering: Nobody uses short max-age lifetimes to allow modifying a static asset in future. When you modify it, you just serve it at a different URL. So no, it's nothing to do with Google doodles. Think about it: even if Google didn't understand this basic trick of HTTP, 8 days still wouldn't be appropriate, as only those users who don't have the original logo cached would see the doodle on doodle-day – and then that group of users would go on seeing the doodle for the following 8 days after Google changed it back :) Web servers do not worry about "filling up" the caches of clients (or proxies). The client manages this by itself – when it hits its own storage limit, it just starts dropping the lowest priority items to make space for new items. The priority score is based on the question "How likely am I to benefit from having cached this URL?", which is nothing to do with what max-age value the server sent when the URL was originally requested; it's a heuristic based on the "frecency" of requests for that URL. The max-age simply lets the server set a cut-off point – the time at which the client is supposed to discard the item regardless of how often it's being re-used. It would be very nice and trusting of a downstream client/proxy to rely on all origin servers "holding back" from filling up their caches, but I don't think we live in that world ;)

• Writing Web "server less" applications

  - by crodjer

  TL;DR What are the prospects of write applications which are completely based on a REST database server (CouchDB) and web applications which directly access the DB instead of having a web server in between? I recently started looking up some NoSQL databases. MongoDB seems to be a popular choices. I also liked the project. But I personally liked the REST interface of CouchDB. So what I wanted to know is if there was the possibility of applications (maybe cached apps in web browser, a chrome extension etc.) which could just just query the database directly with no requirement of a webserver in between. All the computational logic would reside in the client application and the database will do what it does, CRUD. Since mostly (I don't know which doesn't) client frameworks support REST quaries, it could be a good way writing applications well optimized for respective framework. These applications though won't be doing complicated computation, but still provide enough functionality which could replace lots of conventional applications. Are existing resources and projects which would help me move towards writing such applications and also the scope and moving towards developing in this way? Are their any technical/security issues with this? This post will help me decide to look into project like CouchDB (and maybe Dive into Erlang later) or stay with the conventional frameworks (like django) and SQL databases. Update A specific point of such apps I had in mind is creation of offline applications just by replicating couchdb data on client.

• Advice on developing a social network [on hold]

  - by Siraj Mansour

  I am doing research on assembling a team, using the right tools, and the cost to develop a highly responsive social network that is capable of dealing with a lot of users. Similar to the Facebook concept but using the basics package for now. Profile, friends, posts, updates, media upload/download, streaming, chat and Inbox messaging are all in the package. We certainly do not expect it to be as popular as Facebook or handle the same number of users and requests, but in its own game it has to be a monster, and expandable for later on. Neglecting the hosting, and servers part, i am looking for technical advise and opinions, on what kind of team i need ? how many developers ? their expertise ? What are the right tools ? languages ? frameworks ? environments ? Any random ideas about the infrastructure ? Quick thoughts on the development process ? Please use references, if you have any to support your ideas. Development cost mere estimation ? NEGLECTING THE COST OF SERVERS I know my question is too broad but my knowledge is very limited and i need detailed help, for any help you can offer i thank you in advance.

• Advice on software infrastructure for a FLOSS bounty site

  - by michaeljt

  I am planning to set up a simple web site where people can offer bounties for work on FLOSS projects. Unfortunately I have no experience at web development (I am a C/C++ developer), so I was hoping someone might be able to suggest out-of-the-box packages (preferably Debian ones) I could use to build the site from. My idea of how the site would work is to keep things as simple as possible. The person proposing a bounty would enter a description with relevant links (particularly to a bugtracker entry with the project the work is to be done on, where the real discussion and work would take place) and information and place an initial contribution. Other people would be able to add (donate, not pledge) contributions, but any discussion would take place on the project's bugtracker. I am also planning to run a mailing list rather than a forum (at least initially), so that is not a requirement. Paypal seems to me to be the handiest payment mechanism. So overall what I need is probably a simple interface with Paypal integration and a simple database backend. I hope this is the right place for my question, if not I would be grateful for pointers to somewhere better. And of course, this is purely about the technical side, though I am more than happy to discuss other aspects of the project elsewhere.

• How can Highscores be more meaningful and engaging?

  - by Anselm Eickhoff

  I'm developing a casual Android game in which the player's success can very easily be represented by a number (I'm not more specific because I'm interested in the topic in general). Although I myself am not a highscore person at all, I was thinking of implementing a highscore for that game, but I see at least 2 problems in the classical leaderboard approach: very soon the highscore will be dominated by hardcore players, leaving no chance for beginners, who are then frustrated. This is very severe especially in casual games. there is no direct reward for being a loyal player who plays the game over and over again My current idea is to "reset" the highscore every 24 hours (for example) and each day nominate the "player of the day" who then gets a "star". Then there would be some kind of meta-highscore of players with the most stars. That way even beginners might have a chance to be "player of the day" once and continued or repeated play is rewarded much more. The idea is still very rough and there are many problems in the details and the technical implementation but I have a feeling it is a step in the right direction. Do you have creative and new ideas on how to implement highscores? Which games are doing this well / what types of highscores do you find most engaging?

• How can I discourage the use of Access?

  - by Greg Buehler

  Lets pretend that a very large company (revenue numbers with more than 8 figures) is looking to do a refresh on a software system, particularly the dashboard used by employees. This system was originally put together in the early 1990's to handle inventory tracking and storage across a variety of facilities (10+). Since this large company is now in the process of implementing some of these inventory processes with SAP they are in need of a major refresh. The existing system: Microsoft Access project performs dashboard duties Unique shipping/receiving configurations at different facilities require unique forms and queries within the Access project Uses 3rd party libraries referenced by Access to directly interface with at control system (read: motors, conveyors, and counters) Individual SQL Server 2000 instances (some traces of pre-update SQL Server 6.0 documents) at each facility The Issue: This system started as a home brewed inventory tracking scheme with a single internal sponsor who is still in charge of the technical direction. The original sponsor prescribing the desired deliverables that are being called for in the current RFP. The RFP describes a system based around a single Access project. Any suggestion that Access is ill suited for a project of this scope are shot down under the reasoning that "it works for the scope now". Are there any case studies, notices, or statements that can be used to disuade this potential customer from repeating their mistake? Does Microsoft make any statements directly about when it is highly recommended to ditch Access?

• Information about how much time in spent in a function, based on the input of this function

  - by olchauvin

  Is there a (quantitative) tool to measure performance of functions based on its input? So far, the tools I used to measure performance of my code, tells me how much time I spent in functions (like Jetbrain Dottrace for .Net), but I'd like to have more information about the parameters passed to the function in order to know which parameters impact the most the performance. Let's say that I have function like that: int myFunction(int myParam1, int myParam 2) { // Do and return something based on the value of myParam1 and myParam2. // The code is likely to use if, for, while, switch, etc.... } If would like a tool that would allow me to tell me how much time is spent in myFunction based on the value of myParam1 and myParam2. For example, the tool would give me a result looking like this: For "myFunction" : value | value | Number of | Average myParam1 | myParam2 | call | time ---------|----------|-----------|-------- 1 | 5 | 500 | 301 ms 2 | 5 | 250 | 1253 ms 3 | 7 | 1268 | 538 ms ... That would mean that myFunction has been call 500 times with myParam1=1 and myParam2=5, and that with those parameters, it took on average 301ms to return a value. The idea behind that is to do some statistical optimization by organizing my code such that, the blocs of codes that are the most likely to be executed are tested before the one that are less likely to be executed. To put it bluntly, if I know which values are used the most, I can reorganize the if/while/for etc.. structure of the function (and the whole program) to optimize it. I'd like to find such tools for C++, Java or.Net. Note: I am not looking for technical tips to optimize the code (like passing parameters as const, inlining functions, initializing the capacity of vectors and the like).

• Why is there no facility to overload static properties in PHP?

  - by Jon

  Intro PHP allows you to overload method calls and property accesses by declaring magic methods in classes. This enables code such as: class Foo { public function __get($name) { return 42; } } $foo = new Foo; echo $foo->missingProperty; // prints "42" Apart from overloading instance properties and methods, since PHP 5.3.0 we can also overload static methods calls by overriding the magic method __callStatic. Something missing What is conspicuously missing from the available functionality is the ability to overload static properties, for example: echo Foo::$missingProperty; // fatal error: access to undeclared static property This limitation is clearly documented: Property overloading only works in object context. These magic methods will not be triggered in static context. Therefore these methods should not be declared static. As of PHP 5.3.0, a warning is issued if one of the magic overloading methods is declared static. But why? My questions are: Is there a technical reason that this functionality is not currently supported? Or perhaps a (shudder) political reason? Have there been any aborted attempts to add this functionality in the past? Most importantly, the question is not "how can I have dynamic static properties in userland PHP?". That said, if you know of an especially cute implementation based on __callStatic that you want to share then by all means do so.

• bash-like features in sqlplus, rman and other Oracle command line tools

  - by Gilles Haro

  As far as I can remember, I have always been complaining about the lack of “recall last command” from within sqlplus. Such a basic thing, available in any bash shell or windows cmd terminal, remains missing with Oracle command lines tools. Thanks to davidw who published a post in the french blog EASYTEAM, it is now possible to use a simple rpm package rlwrap to enhance sqlplus, dgmgrl, rman, … tools and give them bash “recall/completion” capabilities. I installed it in a few minutes and I am already wondering how can people work without it. The steps are here : Get the rpm file from sites like RPM PBone. AS root, install the package rpm -ivh rlwrap-0.37-1.el5.x86_64.rpm As Oracle, create a dictionnary file (for autocompletion) . This file is made of a series of words to be used for autocompletion. Put in it the list of dictionary tables, the list of sql commands, the list of sqlplus commands… whatever your like. And use the <tab> key as you would in a bash shell. $HOME/.oracle_keywords Create an alias for sqlplus alias sqlplus='/usr/bin/rlwrap -if $HOME/.oracle_keywords $ORACLE_HOME/bin/sqlplus' And enjoy it !!! Thank you DavidW. Gilles Haro Technical Expert - Core Technology, Oracle Consulting  Technorati Tags: rlwrap bash sqlplus

Cloud API and service designers, stop thinking small | Cloud Computing - InfoWorld "The focus must shift away from fine-grained APIs that provide some type of primitive service, such as pushing data to a block of storage or perhaps making a request to a cloud-rooted database," says InfoWorld's David Linthicum. "To go beyond primitives, you must understand how these services should be used in a much larger architectural context. In other words, you need to understand how businesses will employ these services to form real workplace solutions -- inside and outside the enterprise." Oracle Solaris 8 P2V with Oracle database 10.2 and ASM | Orgad Kimchi Orgad Kimchi's technical post illustrates the migration of "a Solaris 8 physical system, with Oracle database version 10.2.0.5 with ASM file-system located on a SAN storage, into a Solaris 8 branded zone inside a Solaris 10 guest domain on top of a Solaris 11 control domain."

• New XAML-Based User Group started in Birmingham, Alabama.

  - by mbcrump

  I’m pleased to announce that a new XAML-Based User Group has started in Birmingham, Alabama. The group is being hosted by Michael Crump and Jonathan Marbutt. The reason is very simple: we feel that Birmingham needs a fresh start. We are both very passionate about .NET and are hoping to share our experiences with the community. We have created a site (http://allaboutxaml.net) and our first meetup is now scheduled. We are here to discuss all things that have to do with xaml. This includes Silverlight, WPF, Windows Phone 7, Surface, Lightswitch and Silverlight with SharePoint 2010. We: believe strongly in xaml and are passionate about what we talk about. believe in an open-forum. believe a user group should be FUN as well as educational. do not claim to be an expert on anything, we are here to share. record every presentation and put it on the web for others to benefit. meet monthly but are flexible on the actual date. do our events outside of technical colleges. have families and our meetings start and stop on time. welcome new speakers. welcome adult beverages. Our first meeting is going to be on February 15th, 2011 (6PM), at Logan's on HWY 280. It is going to be more of a meetup than a meeting. I would like to discuss current xaml-based projects that you are working on and get to know one another. If you are interested in coming then please sign up here so that we know how many to expect. Please visit our site to find out more about us: http://allaboutxaml.net.

• Video on Hyperion Tax Provision

  - by Lia Nowodworska - Oracle

  ( in via Jan) EPM Information Development has asked us to remind you about the new video available for Hyperion Tax Provision. You can view it on the OracleEPMWebcasts YouTube channel here: http://bit.ly/1jxLlCy An information rich 4:40 minutes of your time.  So please take a look. The video gives a brief overview of the main features of  Hyperion Tax Provision. You will learn ... That Tax Provision and reporting System builds on the Hyperion Financial Close Reporting Platform That much of the Tax Provision flow process is similar to the Financial Close Process and that the modules have been aligned to work together very closely. That HTP enables you to integrate Book- and Tax Reporting on a common platform. That It uses the technology of HFM, ties in with SmartView and can be used with Hyperion Financial Reporting. That the native integration between the Financial System and the Tax System creates transparency for the Tax Departments and removes bottlenecks in the tax process. More technical information can be found here: Oracle Hyperion Tax Provision Data Sheet Oracle Hyperion Tax Provision White Paper Oracle Hyperion Tax Provision Documentation If you have another 45 minutes to spare and want to get into greater detail, then you can check out the recording of an Advisor Webcast that we did earlier last year: You can find this via KM Doc Oracle Business Analytics Advisor Webcast Schedule and Archive Recordings (Doc ID 1456233.1) -> Select the Tab "Archived 2013" and it is the third from the top: "Oracle Hyperion Tax Provision - Features and Overview with Demo" If you have questions towards that Advisor Webcast, you may participate in the Community Discussion about it.
