  • Almost time to hit the road again

    - by Chris Williams
    I’ve had a few months of not much traveling, but now that the weather is improving… conference season is starting up again. That means it’s time for me to start hitting the road. In June, I have Tech Ed 2010 in New Orleans, LA. I lived in New Orleans for several years, both as military and civilian and I have a few friends still down there. I haven’t been there since before Hurricane Katrina, so I have mixed feelings about returning… but I am still looking forward to it. Also in June, I have Codestock in Knoxville, TN. Codestock is one of my favorite events, primarily because of the excellent people that speak there and also attend sessions. It’s a great mix of people and technologies. Sometime in July or August, I’m headed to Austin, TX for a couple days. I don’t know the exact date yet, but if you have an event down there in that timeframe, let me know and maybe we can sort something out. In September, I’m heading to Seattle for my first PAX (Penny Arcade Expo.)  I’m going strictly as an attendee and it looks like a LOT of fun. Really excited to check it out. Also in September, I’m headed to Omaha for the Heartland Developers Conference. This is a FANTASTIC event, and certainly one of my local favorites. (I guess local is relative, it’s about a 6 hour drive.) In addition to speaking on WP7, I’ll be doing a series of hands on labs on XNA they day before the conference starts, so that should be a lot of fun as well.   In addition to all this stuff, I have my own XNA User Group to take care of. In August, Andy “The Z-Man” Dunn is coming to speak and check out the various food on a stick offerings at the Minnesota State Fair!

  • GWB -- Little More Interesting Info

    - by lavanyadeepak
    GWB -- Little More Interesting Info Whilst writing the post on 'Warming with GWB', I just recalled another historic entity often shortly known as GWB. It is in fact 'GWBasic' which we I started programming about fifteen years back way back in 1994 to 1995.   GWBASIC was actually a version of BASIC in the lines of BASICA from Compaq. Eventually it was absorbed into QBasic and QuickBasic suite of products. Just thought I would share this recollection too in this context.

  • Running Multiple sites with multiple domains apache

    - by PsychoData
    I am having a rough time running apache and using multiple domain names here is a snippet of my config file. I keep getting a error saying that NameVirtualHost has no VirtualHosts. I want them both running on the same IP and I'm not sure why this doesn't work. I've been digging through the documentation for VirtualHosts, NameVirtualHost, and apache's page about name based virtual hosting. That example in the name based page is almost exactly my config! What am I doing wrong? Listen *:80 NameVirtualHost *:80 <VirtualHost *:80> ServerName www.sample1.net DocumentRoot /var/www/sample1-net </VirtualHost> <VirtualHost *:80> ServerName www.example2.net DocumentRoot /var/www/example2-net </VirtualHost>

  • What emulator / VM software can I use to create a Win32-portable Linux Guest?

    - by Jotham
    Hi, I want to create a portable VM setup so that I can boot a Linux install regardless of which Windows XP / Windows 7 host machine I am on. I was looking at Qemu but it doesn't appear to have a relatively safe win32 build. Other things like VirtualBox require complete install on the host OS for performance reasons. I'm not so concerned about performance, I just want to run a few curses based applications. My ideal end goal would be a a memory stick of some size with a VM/Emulator I can boot on most WinXP/Windows 7 machines and access my own curses based applications (probably archlinux or debian). Any help would be appreciated. Regards,

  • Recommend an SFTP solution for Windows (Server & Client) that integrates well with Dreamweaver

    - by aaandre
    Could you please recommend a secure FTP solution for updating files on a remote windows server from windows workstations? We would like to replace the FTP-based workflow with a secure FTP one. Windows Server 2003 on the remotely hosted webserver, WinXP on the workstations. We manage the files via Dreamweaver's built-in FTP. My understanding is Dreamweaver supports sFTP out of the box so I guess I am looking for a good sFTP server for Windows Server 2003. Ideally, that would not require cygwin. Ideally, the solution would use authentication based on the existing windows accounts and permissions. Thank you!

  • Shared resources in Windows Server 2008 were lost

    - by user316687
    We have an Oracle database in Windows Server 2003, which has its archived redo logs stored on a shared resource of a Windows Server 2008: \\192.168.1.189\d$\folder_for_archivedlogs However, according to Oracle's alert.log, at 10:01 p.m that shared resource got lost and the database was inaccessible. From my Windows Server 2003, on Windows Explorer, I couldn't access that shared resource, but I got a response when I did ping 192.168.1.189. I reviewed all the Event Logs on that Windows 2008, but there is no error at 10:00pm or 11:00pm. Has anyone seen some similar case before? (Shared resources get lost, but you still can ping the server and there are no error events in the Event Logs).

  • Copy/move EBS volume from one Region to another

    - by Gnanam
    Background of our setup: We've hosted our web-based application in Amazon EC2 US East (Virginia) Region. Our instance is based on Linux distribution (CentOS) and AMI is S3-backed. 1 EBS volume (400 GB size) is attached to this instance. Question: We've planned to migrate our deployment to US West (N. California) Region. From AWS doc, I understood that for moving AMI, there is a command-line tool available - ec2-migrate-bundle. But for moving EBS volume across Region, currently there is no tool available. I'm looking for easiest and/or fastest way of copying/moving EBS volume from one Region to another. Also, are there any hidden risks involved during and/or after the migration? Experts ideas/suggestions/recommendations on this are highly 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 ;)

  • C# 5: At last, async without the pain

    - by Alex.Davies
    For me, the best feature in Visual Studio 11 is the async and await keywords that come with C# 5. I am a big fan of asynchronous programming: it frees up resources, in particular the thread that a piece of code needs to run in. That lets that thread run something else, while waiting for your long-running operation to complete. That's really important if that thread is the UI thread, or if it's holding a lock because it accesses some data structure. Before C# 5, I think I was about the only person in the world who really cared about asynchronous programming. The trouble was that you had to go to extreme lengths to make code asynchronous. I would forever be writing methods that, instead of returning a value, accepted an extra argument that is a "continuation". Then, when calling the method, I'd have to pass a lambda in to it, which contained all the stuff that needed to happen after the method finished. Here is a real snippet of code that is in .NET Demon: m_BuildControl.FilterEnabledForBuilding(     projects,     enabledProjects = m_OutOfDateProjectFinder.FilterNeedsBuilding(         enabledProjects,         newDirtyProjects =         {             // Mark any currently broken projects as dirty             newDirtyProjects.UnionWith(m_BrokenProjects);             // Copy what we found into the set of dirty things             m_DirtyProjects = newDirtyProjects;             RunSomeBuilds();         })); It's just obtuse. Who puts a lambda inside a lambda like that? Well, me obviously. But surely enabledProjects should just be the return value of FilterEnabledForBuilding? And newDirtyProjects should just be the return value of FilterNeedsBuilding? C# 5 async/await lets you write asynchronous code without it looking so stupid. Here's what I plan to change that code to, once we upgrade to VS 11: var enabledProjects = await m_BuildControl.FilterEnabledForBuilding(projects); var newDirtyProjects = await m_OutOfDateProjectFinder.FilterNeedsBuilding(enabledProjects); // Mark any currently broken projects as dirty newDirtyProjects.UnionWith(m_BrokenProjects); // Copy what we found into the set of dirty things m_DirtyProjects = newDirtyProjects; RunSomeBuilds(); Much easier to read! But how is this the same code? If we were on the UI thread, doesn't the UI thread have to block while FilterEnabledForBuilding runs? No, it doesn't, and that's the magic of the await keyword! It cuts your method up into its constituent pieces, much like I did manually with lambdas before. When you run it, only the piece up to the first await actually runs. The rest is passed to FilterEnabledForBuilding as a continuation, which will get called back whenever that method is finished. In the meantime, our thread returns, and can go back to making the UI responsive, or whatever else threads do in their spare time. This is actually a massive simplification, and if you're interested in all the gory details, and speed hacks that the await keyword actually does for you, I recommend Jon Skeet's blog posts about it.

  • C# Dev - I've tried Lisps, but I don't get it.

    - by Jonathan Mitchem
    After a few months of learning about and playing with lisps, both CL and a bit of Clojure, I'm still not seeing a compelling reason to write anything in it instead of C#. I would really like some compelling reasons, or for someone to point out that I'm missing something really big. The strengths of a Lisp (per my research): Compact, expressive notation - More so than C#, yes... but I seem to be able to express those ideas in C# too. Implicit support for functional programming - C# with LINQ extension methods: mapcar = .Select( lambda ) mapcan = .Select( lambda ).Aggregate( (a,b) = a.Union(b) ) car/first = .First() cdr/rest = .Skip(1) .... etc. Lambda and higher-order function support - C# has this, and the syntax is arguably simpler: "(lambda (x) ( body ))" versus "x = ( body )" "#(" with "%", "%1", "%2" is nice in Clojure Method dispatch separated from the objects - C# has this through extension methods Multimethod dispatch - C# does not have this natively, but I could implement it as a function call in a few hours Code is Data (and Macros) - Maybe I haven't "gotten" macros, but I haven't seen a single example where the idea of a macro couldn't be implemented as a function; it doesn't change the "language", but I'm not sure that's a strength DSLs - Can only do it through function composition... but it works Untyped "exploratory" programming - for structs/classes, C#'s autoproperties and "object" work quite well, and you can easily escalate into stronger typing as you go along Runs on non-Windows hardware - Yeah, so? Outside of college, I've only known one person who doesn't run Windows at home, or at least a VM of Windows on *nix/Mac. (Then again, maybe this is more important than I thought and I've just been brainwashed...) The REPL for bottom-up design - Ok, I admit this is really really nice, and I miss it in C#. Things I'm missing in a Lisp (due to a mix of C#, .NET, Visual Studio, Resharper): Namespaces. Even with static methods, I like to tie them to a "class" to categorize their context (Clojure seems to have this, CL doesn't seem to.) Great compile and design-time support the type system allows me to determine "correctness" of the datastructures I pass around anything misspelled is underlined realtime; I don't have to wait until runtime to know code improvements (such as using an FP approach instead of an imperative one) are autosuggested GUI development tools: WinForms and WPF (I know Clojure has access to the Java GUI libraries, but they're entirely foreign to me.) GUI Debugging tools: breakpoints, step-in, step-over, value inspectors (text, xml, custom), watches, debug-by-thread, conditional breakpoints, call-stack window with the ability to jump to the code at any level in the stack (To be fair, my stint with Emacs+Slime seemed to provide some of this, but I'm partial to the VS GUI-driven approach) I really like the hype surrounding Lisps and I gave it a chance. But is there anything I can do in a Lisp that I can't do as well in C#? It might be a bit more verbose in C#, but I also have autocomplete. What am I missing? Why should I use Clojure/CL?

  • Baseline for GIS Applications

    - by Geertjan
    The application I introduced here yesterday can best be understood via its author's explanation: "As I developed several different WorldWind-based applications, I noticed that they all started out the same. Terramenta was born so I wouldn't have to recreate the baseline every time, I could just provide NetBeans plugin modules to introduce the new features required by different projects." So, to try it out for myself, I checked out the sources from the Mercurial repo today, built them, and ran them. hg clone https://bitbucket.org/heidtmare/terramenta On Windows, things worked fine, on Ubuntu they didn't because the relevant native libraries aren't provided yet out of the box. Here's the result: The above provides the WorldWind globe, together with all the standard options, e.g., for showing names and other WorldWind features, together with several features that I don't understand yet, such as tools for creating shapes and a recorder for replaying sequences. The complete application is like this, i.e., one single functionality module is provided, which exposes several API packages that can be extended: It would really be cool if the above module could also be added to a Maven-based application via a reference to a Maven repository, in the way that Timon Veenstra and the AgroSense team have made available their GeoViewer. One cool thing from the GeoViewer solution is the Flamingo menubar, which I added to Terramenta by simply putting the dependency below into the application POM: <dependency>    <groupId>nl.cloudfarming.client</groupId>    <artifactId>menu</artifactId>    <version>1.0.24</version></dependency> The result, without doing anything other than the above: I am looking forward to helping to document the use cases and developer scenarios for Terramenta! Something like this, created by Timon to demonstrate the GeoViewer use case would be cool to have: http://java.net/projects/agrosense/pages/ExampleGeoviewerNormal
