  • Does F# kill C++?

    - by MarkPearl
    Okay, so the title may be a little misleading… but I am currently travelling and so have had very little time and access to resources to do much fsharping – this has meant that I am right now missing my favourite new language. I was interested to see this post on Stack Overflow this evening concerning the performance of the F# language. The person posing the question asked 8 key points about the F# language, namely… How well does it do floating-point? Does it allow vector instructions How friendly is it towards optimizing compilers? How big a memory foot print does it have? Does it allow fine-grained control over memory locality? Does it have capacity for distributed memory processors, for example Cray? What features does it have that may be of interest to computational science where heavy number processing is involved? Are there actual scientific computing implementations that use it? Now, I don’t have much time to look into a decent response and to be honest I don’t know half of the answers to what he is asking, but it was interesting to see what was put up as an answer so far and would be interesting to get other peoples feedback on these questions if they know of anything other than what has been covered in the answer section already.

  • 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.

  • Encrypt SSD or not?

    - by JamesBradbury
    My desktop machine is running Ubuntu 12.04 (and will probably stay with it until the next LTS). I've got a new 120GB SSD on the way as my existing 420GB spinning disk. If it makes any difference I'll be dual-booting with Windows 7 across both disks too. I've read some helpful answers here about /home setup and enabling TRIM, which I intend to follow. So most of my /home will be on the SSD, with only photos, videos and music on the spinning disk. The question is, when I reinstall Ubuntu from CD or USB, whether I should encrypt the SSD? Specifically: I'm reading that drive wear isn't much of an issue with modern SSDs as they last decades even if you spam them. Is this true? How big a performance reduction will encrypting cause (I have an i7 Sandybridge, so I guess it can cope)? Is it more important from a security point of view to encrypt an SSD? I think I read somewhere that it may be hard to reliably wipe data. By all means answer even if you only know about one of those things.

  • Do you know how to move the Team Foundation Server cache

    - by Martin Hinshelwood
    There are a number of reasons why you may want to change the folder that you store the TFS Cache. It can take up “some” amount of room so moving it to another drive can be beneficial. This is the source control Cache that TFS uses to cache data from the database. Moving the Cache is pretty easy and should allow you to organise your server space a little more efficiently. You may also get a performance improvement (although small) by putting it on another drive.. Create a new directory to store the Cache. e.g. “d:\TfsCache\” Figure: Create a new folder Give the local TFS WPG group full control of the directory   Figure: You need to use the App Tier Service WPG In the application tier web.config (~\Application Tier\Web Services\web.config) add the following setting (to the appSettings section). Figure: The web.config for TFS is stored in the application folder <appsettings> ... <add value="D:\" key="dataDirectory" /> ... </appsettings> Figure: Adding this to the web.config will trigger a restart of the app pool Figure: Your web.config should look something like this The app pool will automatically recycle and Team Web Access will start using the new location.  If you then download a file (not via a proxy) a folder with a GUID should be created immediately in the folder from #1.  If the folder doesn’t appear, then you probably don’t have permissions set up properly.

  • Upcoming events : OBUG Connect Conference 2012

    - by Maria Colgan
    The Oracle Benelux User Group (OBUG) have given me an amazing opportunity to present a one day Optimizer workshop at their annual Connect Conference in Maastricht on April 24th. The workshop will run as one of the parallel tracks at the conference and consists of three 45 minute sessions. Each session can be attended stand alone but they will build on each other to allow someone new to the Oracle Optimizer or SQL tuning to come away from the conference with a better understanding of how the Optimizer works and what techniques they should deploy to tune their SQL. Below is a brief description of each of the sessions Session 7 - 11:30 am Oracle Optimizer: Understanding Optimizer StatisticsThe workshop opens with a discussion on Optimizer statistics and the features introduced in Oracle Database 11g to improve the quality and efficiency of statistics-gathering. The session will also provide strategies for managing statistics in various database environments. Session 27 -  14:30 pm Oracle Optimizer: Explain the Explain PlanThe workshop will continue with a detailed examination of the different aspects of an execution plan, from selectivity to parallel execution, and explains what information you should be gleaning from the plan. Session 47 -  15:45 pm Top Tips to get Optimal Execution Plans Finally I will show you how to identify and resolving the most common SQL execution performance problems, such as poor cardinality estimations, bind peeking issues, and selecting the wrong access method.   Hopefully I will see you there! +Maria Colgan

  • How to cover the widest range of computers when publishing?

    - by DevilWithin
    When you plan a game, or even when you already made a game, and its time to publish, you wonder how much of your audience is covered by the game technology demands. I'm directing this essentialy to casual games, as I constantly see people having old laptops and being unable to replace them. Laptops with integrated cards whose OpenGL version doesn't even support textures larger than 1024x1024. These people may be avid gamers as well, and a reasonable share of the audience to consider giving them the chance to play casual games, once they cannot play any blockbusters. As I've seen happening, a very "noticeable" example is Angry Birds. It's gameplay is merely casual (I think nobody disagrees here) and still, it uses so high resolution textures that at least OpenGL 2.0 or around is needed, which blocks away a lot of people. So, the actual question is: what is a good tradeoff for this issue? Would it be better to just sacrifice the texture resolution for everyone, but have more supported hardware? Would it be better to keep the high quality and just slice the textures into smaller ones, sacrificing the performance a little bit? What else? Any ideas about this topic are welcome for discussion.

  • Financial institutions build predictive models using Oracle R Enterprise to speed model deployment

    - by Mark Hornick
    See the Oracle press release, Financial Institutions Leverage Metadata Driven Modeling Capability Built on the Oracle R Enterprise Platform to Accelerate Model Deployment and Streamline Governance for a description where a "unified environment for analytics data management and model lifecycle management brings the power and flexibility of the open source R statistical platform, delivered via the in-database Oracle R Enterprise engine to support open standards compliance." Through its integration with Oracle R Enterprise, Oracle Financial Services Analytical Applications provides "productivity, management, and governance benefits to financial institutions, including the ability to: Centrally manage and control models in a single, enterprise model repository, allowing for consistent management and application of security and IT governance policies across enterprise assets Reuse models and rapidly integrate with applications by exposing models as services Accelerate development with seeded models and common modeling and statistical techniques available out-of-the-box Cut risk and speed model deployment by testing and tuning models with production data while working within a safe sandbox Support compliance with regulatory requirements by carrying out comprehensive stress testing, which captures the effects of adverse risk events that are not estimated by standard statistical and business models. This approach supplements the modeling process and supports compliance with the Pillar I and the Internal Capital Adequacy Assessment Process stress testing requirements of the Basel II Accord Improve performance by deploying and running models co-resident with data. Oracle R Enterprise engines run in database, virtually eliminating the need to move data to and from client machines, thereby reducing latency and improving security"

  • Using Behavior Trees and Events together

    - by weichsem
    I am beginning to work with behavior trees and am unsure how events should be handled within the tree. Lets say we have a space game where the player is dogfighting with a handful of other ships, some friendly some not. The player destroys a ship and the rest of the hostile ships should then start to retreat. How was should the shipWasDestroyed event effect the other ship's behavior trees so that they start running the retreat behavior? One way I could think of doing this is have all the conditions I care about be high level nodes that effectively state change the ship. This would mean I'd have to check all of these state change conditions on every frame the behavior tree was run, even if they are very rare occurrences. I'd prefer not doing this for performance and complexity reasons. From looking at the Halo papers on behavior trees it seems that they handled this by dynamically placing nodes into the tree when the event occurred. It seems like calculating where the new node should go could be problematic depending on the current state of the running behavior. How is this normally handled?

  • Generalise variable usage inside code

    - by Shirish11
    I would like to know if it is a good practice to generalize variables (use single variable to store all the values). Consider simple example Strings querycre,queryins,queryup,querydel; querycre = 'Create table XYZ ...'; execute querycre ; queryins = 'Insert into XYZ ...'; execute queryins ; queryup = 'Update XYZ set ...'; execute queryup; querydel = 'Delete from XYZ ...'; execute querydel ; and Strings query; query= 'Create table XYZ ... '; execute query ; query= 'Insert into XYZ ...'; execute query ; query= 'Update XYZ set ...'; execute query ; query= 'Delete from XYZ ...'; execute query ; In first case I use 4 strings each storing data to perform the actions mentioned in their suffixes. In second case just 1 variable to store all kinds the data. Having different variables makes it easier for someone else to read and understand it better. But having too many of them makes it difficult to manage. Also does having too many variables hamper my performance?

  • Price Drop for Processor based License on Exalytics

    - by Mike.Hallett(at)Oracle-BI&EPM
    ·       33% reduction in the list `per processor` license pricing for the Oracle BI Foundation Suite ·       New capacity-based licensing which allows customers to think big & start small, significantly lowering the entry price point for an Exalytics. Oracle BI Software List Price changes In response to new powerful platforms like the in-memory Oracle Exalytics with 40 cpu cores (counted under Oracle pricing policy as 20 “processors”), the list price of “Oracle BI Foundation Suite” (BIFS) is reduced by 33% from $450K per processor to $300K per processor. Capacity-based licensing on Exalytics (Trusted Partitions) “Capacity-based pricing” for the BIFS, Endeca, Essbase and Times Ten for Exalytics software is now available for Exalytics systems. This is delivered using “Oracle VM” (OVM).  We still ship a full Exalytics machine to all customers, but they may choose to only use and license a subset of the processors installed in the machine.   Customers can license Exalytics software in units of 5 “processors”: 5, 10, 15 or the full capacity 20.   As the customer’s implementation and workload increases, it is a simple matter to license additional processors and, using OVM, make them available to the BI or EPM application. Endeca Information Discovery now available on Exalytics Oracle has also announced the certification of “Oracle Endeca Information Discovery” (EID) on the Exalytics machine.    EID can be licensed alone or in combination with the BIFS & Times Ten for an Exalytics stack, and also participates in the capacity based pricing outlined above.   The Exalytics hardware is the perfect platform for EID, and provides superb power and performance for this in-memory hybrid text-search-analytics.   For more information : Oracle Price lists Oracle Partitioning Policy Discussion by Mark Rittman (Rittman Mead Consulting ltd.) on Oracle Trusted Partitions for Oracle Engineered Systems, Oracle Exalytics and Updated BI Foundation Pricing.

  • Refactoring and Open / Closed principle

    - by Giorgio
    I have recently being reading a web site about clean code development (I do not put a link here because it is not in English). One of the principles advertised by this site is the Open Closed Principle: each software component should be open for extension and closed for modification. E.g., when we have implemented and tested a class, we should only modify it to fix bugs or to add new functionality (e.g. new methods that do not influence the existing ones). The existing functionality and implementation should not be changed. I normally apply this principle by defining an interface I and a corresponding implementation class A. When class A has become stable (implemented and tested), I normally do not modify it too much (possibly, not at all), i.e. If new requirements arrive (e.g. performance, or a totally new implementation of the interface) that require big changes to the code, I write a new implementation B, and keep using A as long as B is not mature. When B is mature, all that is needed is to change how I is instantiated. If the new requirements suggest a change to the interface as well, I define a new interface I' and a new implementation A'. So I, A are frozen and remain the implementation for the production system as long as I' and A' are not stable enough to replace them. So, in view of these observation, I was a bit surprised that the web page then suggested the use of complex refactorings, "... because it is not possible to write code directly in its final form." Isn't there a contradiction / conflict between enforcing the Open / Closed Principle and suggesting the use of complex refactorings as a best practice? Or the idea here is that one can use complex refactorings during the development of a class A, but when that class has been tested successfully it should be frozen?

  • Why don't C++ Game Developers use the boost library?

    - by James
    So if you spend any time viewing / answering questions over on Stack Overflow under the C++ tag, you will quickly notice that just about everybody uses the boost library; some would even say that if you aren't using it, you're not writing "real' C++ (I disagree, but that's not the point). But then there is the game industry, which is well known for using C++ and not using boost. I can't help but wonder why that is. I don't care to use boost because I write games (now) as a hobby, and part of that hobby is implementing what I need when I am able to and using off-the-shelf libraries when I can't. But that is just me. Why don't game developers, in general, use the boost library? Is it performance or memory concerns? Style? Something Else? I was about to ask this on stack overflow, but I figured the question is better asked here. EDIT : I realize I can't speak for all game programmers and I haven't seen all game projects, so I can't say game developers never use boost; this is simply my experience. Allow me to edit my question to also ask, if you do use boost, why did you choose to use it?

  • Experiences with Ubuntu One?

    - by rsuarez
    I'm currently testing several backup/sync services: Dropbox, SpiderOak and Ubuntu One. Of them, Dropbox is the winner hands down; SpiderOak is nice too, but a bit more intrusive and unpredictable (sometimes is slow in syncing some files, or doesn't sync them at all). Ubuntu One has promise, but I've used it much less than the other two. I'm thinking about buying a "20 pack" and using Ubuntu One as my only synchronization software. It's the cheapest of them all (3$/month vs 10$ in Dropbox and SpiderOak), and 20GB of space is enough for me. My intention is to sync most of my $HOME folder. All the computers I'll connect will have Ubuntu installed, so not being multiplatform doesn't really matter to me. If its performance is as good as Dropbox's, I'm sold. But I'd like to gauge some experiences here first. Is anyone using it seriously? I.e., to sync a lot of files that change often (like the aforementioned $HOME folder, program sources, or something alike). What have been your experiences? Thanks in advance.

    With 2012 coming to an end soon, we find ourselves reflecting on the year behind us and the year ahead. Now is a good time for reflection on your customer experience initiatives to see how far you have come and where you need to go. Looking back on your customer experience efforts this year, were you able to accomplish the following? Customer journey mapping Align processes across the entire customer lifecyle (buying and owning) Connect all functional areas to the same customer data Deliver consistent and personal experiences across all customer touchpoints Make it easy and rewarding to be your customer Hire and develop talent that drives better customer experiences Tie key performance indicators (KPIs) to each of your customer experience objectives This is by no means a complete checklist for your customer experience strategy, but it does help you determine if you have moved in the right direction for delivering great customer experiences. If you are just getting started with customer experience planning or were not able to get to everything on your list this year, consider focusing on customer journey mapping in 2013. This exercise really helps your organization put your customer in the center and understand how everything you do affects that customer. At Oracle, we see organizations in various stages of customer experience maturity all learn a lot when they go through journey mapping. Companies just starting out with customer experience get a complete understanding of what it is like to be a customer and how everything they do affects that customer. And, organizations that are further along with customer experience often find journey mapping helps provide perspective when re-visiting their customer experience strategy. Happy holidays and best wishes for delivering great customer journeys in 2013!

  • Java Champion Dick Wall Explores the Virtues of Scala (otn interview)

    - by Janice J. Heiss
    In a new interview up on otn/java, titled “Java Champion Dick Wall on the Virtues of Scala (Part 2),” Dick Wall explains why, after a long career in programming exploring Lisp, C, C++, Python, and Java, he has finally settled on Scala as his language of choice. From the interview: “I was always on the lookout for a language that would give me both Python-like productivity and simplicity for just writing something and quickly having it work and that also offers strong performance, toolability, and type safety (all of which I like in Java). Scala is simply the first language that offers all those features in a package that suits me. Programming in Scala feels like programming in Python (if you can think it, you can do it), but with the benefit of having a compiler looking over your shoulder and telling you that you have the wrong type here or the wrong method name there.The final ‘aha!’ moment came about a year and a half ago. I had a quick task to complete, and I started writing it in Python (as I have for many years) but then realized that I could probably write it just as fast in Scala. I tried, and indeed I managed to write it just about as fast.”Wall makes the remarkable claim that once Java developers have learned to work in Scala, when they work on large projects, they typically find themselves more productive than they are in Java. “Of course,” he points out, “people are always going to argue about these claims, but I can put my hand over my heart and say that I am much more productive in Scala than I was in Java, and I see no reason why the many people I know using Scala wouldn’t say the same without some reason.”Read the interview here.

  • Augmenting functionality of subclasses without code duplication in C++

    - by Rob W
    I have to add common functionality to some classes that share the same superclass, preferably without bloating the superclass. The simplified inheritance chain looks like this: Element -> HTMLElement -> HTMLAnchorElement Element -> SVGElement -> SVGAlement The default doSomething() method on Element is no-op by default, but there are some subclasses that need an actual implementation that requires some extra overridden methods and instance members. I cannot put a full implementation of doSomething() in Element because 1) it is only relevant for some of the subclasses, 2) its implementation has a performance impact and 3) it depends on a method that could be overridden by a class in the inheritance chain between the superclass and a subclass, e.g. SVGElement in my example. Especially because of the third point, I wanted to solve the problem using a template class, as follows (it is a kind of decorator for classes): struct Element { virtual void doSomething() {} }; // T should be an instance of Element template<class T> struct AugmentedElement : public T { // doSomething is expensive and uses T virtual void doSomething() override {} // Used by doSomething virtual bool shouldDoSomething() = 0; }; class SVGElement : public Element { /* ... */ }; class SVGAElement : public AugmentedElement<SVGElement> { // some non-trivial check bool shouldDoSomething() { /* ... */ return true; } }; // Similarly for HTMLAElement and others I looked around (in the existing (huge) codebase and on the internet), but didn't find any similar code snippets, let alone an evaluation of the effectiveness and pitfalls of this approach. Is my design the right way to go, or is there a better way to add common functionality to some subclasses of a given superclass?

  • Fresh install on SSD with Ubuntu and Windows Vista, using whole disk encryption for Ubuntu

    - by nategator
    I would like to do a fresh install on a OCZ Vertex Plus R2 SSD 60GB drive I purchased on the cheap. Since the AES-encryption looks like it may not work optimally for this drive, I would like to set up a dual-boot to Windows Vista (the only Windows copy I have for clean install purposes) and Ubuntu 12.04 with the best encryption scheme possible. My plan is to have Windows around just in case I need to use a program that won't work with Wine and Ubuntu as my daily OS with all of my information secured in case the laptop is ever stolen or sold. Although this setup will not provide a lot of space, I think I can squeeze both OSes and have enough for second-computer office tasks. So, my questions are: Which OS should I install first, Ubuntu or Vista? Any special considerations when partitioning the drive? How should I install Ubuntu to ensure full disk encryption for the Linux partition(s) and or my daily computing? Is there a significant performance upgrade with doing a solo install of Ubuntu instead of a dual boot setup? Will TRIM, for example, work correctly? Are there any significant security concerns with going the route of a dual-boot, other than the fact that any activity on Windows may be fully recoverable if the drive is stolen or sold? Thanks in advance!

  • Lubuntu 12.04 on Acer laptop boots to blank blue screen

    - by WGCman
    My previous question on this was closed, but I am posting it again as the solution which my son eventually found may assist other users of the forum, or someone may be able to tweak the solution to improve the performance. Having installed Kubuntu 12.04.01 from a live USB onto my desktop, I wanted to do the same on my laptop, an Acer Aspire 1362 Laptop, which has 256MB RAM (actually 512 "on the box", but a good deal can be borrowed by the graphics!). I found Kubuntu wouldn't run on so little memory but downloaded: Lubuntu-12.04-alternate-i386.iso, which I understood was light enough to go. The laptop has one internal 40GB Toshiba hard drive divided into 3 partitions: C,19GB with Windows XP, Windows program files and some data, D, 19GB mostly data, and a small 2GB partition with some Acer software, which XP can't normally “see”. I transferred most of the contents of D to a memory stick, leaving 16GB free for Lubuntu. I did not want to dump XP yet, though it is painfully slow. I installed Lubuntu from then USB stick, accepting the default answers to most of the questions. The D: partition was further partitioned into a 500MB boot partition, 10GB for Linux, 2GB Swap and 6GB for data shareable between Linux and Windows. I had no error messages during installation, rebooted, was offered the choice of Ubuntu or XP, and selected the former. After a few minutes, I get a dark blue screen announcing Lubuntu with five dots underneath which lighten in turn. Eventually the lights stopped, and whatever I try the screen remains blank apart from “Lubuntu” I tried several solutions suggested on the forum for “identical” questions but without success.

  • Cropping images & SEO

    - by user1181950
    So I have a page with a bunch of images with largely varying sizes. Also the layout of the page is such that the images are all in the shape of square tiles, so just resizing will cause distorted images. What I've been doing previously is when users upload images, I resize and crop them appropriately and display the new image as the thumbnail and load full image when user clicks on it. However, I just realized this is an issue with SEO as google will crawl the thumbnails and stick the thumbnails on Google Images instead of the full images. Is there any way to show a cropped/resized image but have Google Image show the full image? I can do something with css using an enclosing div and overflow:hidden, but I'd imagine the performance on that would be pretty bad. Any suggestions? Thanks! PS. I saw this (Make google index the actual image not the thumbnail), but in my case I have users continuously uploading images, and the database of images is always changing and pretty big (thousands), so sitemap will be pretty unwieldy..

  • Ubuntu 12.04 Faster boot, Hibernate & other questions

    - by Samarth Shukla
    I've recently started exploring Ubuntu (my 1st distro). I fresh installed precise without a swap (4GB ram). The only issues are, slow boot (regardless of the swap) and instability after a few days of installation. The runtime performance is immaculate otherwise. Even though not needed, I still set swappiness = 10. I've tried the quiet splash profile to GRUB; already have preload installed. But it still is pretty slow. I am not too confident on recompiling the kernel yet. But you could please advice me on that too. I've also added the following to fstab: #Move /tmp to RAM: tmpfs /tmp tmpfs defaults,noexec,nosuid 0 0 (Also if you could please tell me the exact implication/scope of this tweak on physical ram & the swap.) But nothing has happened really. So what alternatives are there to make it boot faster? Also, right after fresh install, though no swap partition, the system still showed /dev/zram0 of arond 2GB which was never used (probably because of the above fstab edit). Finally, I experimented with Hibernate a little, but many claim that it doesn't work on 12.04. (Not to mention, I made a swap file of 4GB for it). What I did was: sudo gedit /var/lib/polkit-1/localauthority/50-local.d/hibernate.pkla Then I added the following lines, saved the file, and closed the text editor: [Re-enable Hibernate] Identity=unix-user:* Action=org.freedesktop.upower.hibernate ResultActive=yes I also edited the upower policy for hibernate: gksudo gedit /usr/share/polkit-1/actions/org.freedesktop.upower.policy I added these lines: < allow_inactive >no< /allow_inactive > < allow_active >yes< /allow_active > But it did not work. So is there an alternate method perhaps that can make it work on 12.04?
