  • NVIDIA error "fallen off the bus"

    - by yurividal
    i have been having a Serious Issue with my LG notebook and its Nvidia Geforce 310M GPU. It usualy (99% of the time) happens when i leave the computer idle for a while, but it has also happened sometimes while i was using the PC. Suddenly, (usualy when computer is idle) the screen goes black, and the pc freezes completely on the black screen. (not even ping responses). The only sollution is to Hard Reset the machine. When analizing the syslog, i see the following error: Sep 18 20:58:08 yuri-notebook kernel: [ 1936.510073] NVRM: GPU at 0000:01:00.0 has fallen off the bus. Sep 18 20:58:08 yuri-notebook kernel: [ 1936.510087] NVRM: GPU at 0000:01:00.0 has fallen off the bus.

The problem does not seem to be hardware, because when i boot into windows 7, it works normaly, for days. I am desperate with this problem, because it makes my Ubuntu practicaly unusable. Thanks in advance, Yuri

  • How can create the smallest possible mirror of the archive?

    - by Registered User
    I need to create an http url at my laptop to have a Ubuntu installation begin within my laptop on a Xen environment. This is how the final thing will look like. The host and client are both going to be my laptop, I Googled and came across apt-mirror and some other packages. I do not want to archive entire 15 GB Ubuntu repositories on my machine. It is not possible to use a CD,ISO,loop mounted disk (reason mentioned below). I have tried using netboot image on local machine which failed because if you are attempting to create a virtual machine on a hardware which does not support VT virt-manager installer necessarily needs a URL of this sort http://archive.ubuntu.com/ubuntu/dists/hardy/main/installer-i386/current/images/netboot/ Any other option to create guest OS is simply grayed out. The unfortunate part is my Ethernet connections do not work when I boot with Xen-4.0 and a pv-ops Dom0 kernel from Jeremy's tree. Which is where I have to do this work. So I have to create a URL structure which is similar to Ubuntu mirrors. So how can I do this in bare minimum so that at least the console boots and once the console comes I can do some work.

  • OpenGL CPU vs. GPU

    - by Nitrex88
    So I've always been under the impression that doing work on the GPU is always faster than on the CPU. Because of this, in OpenGL, I usually try to do intensive tasks in shaders so they get the speed boost from the GPU. However, now I'm starting to realize that some things simply work better on the CPU and actually perform worse on the GPU (particularly when a geometry shader is involved). For example, in a recent project I did involving procedurally generated terrain, I tried passing a grid of single triangles into a geometry shader, and tesselated each of these triangles into quads with 400 vertices whose height was determined by a noise function. This worked fine, and looked great, but easily maxed out the GPU with only 25 base triangles and caused a very slow framerate. I then discovered that tesselating on the CPU instead, and setting the height (using noise function) in the vertex shader was actually faster! This prompted me to question the benefits of using the GPU as much as possible... So, I was wondering if someone could describe the general pros and cons of using the GPU vs CPU for intensive graphics tasks. I know this mainly comes down to what your trying to achieve, so if necessary, use the above scenario to discuss why the "CPU + vertex shader" was actually faster than doing everything in the geometry shader on the GPU. It's possible my hardware (newest macbook pro) isn't optomized well for the geometry shader (thus causing the slow framerate). Also, I read that the vertex shader is very good with parallelism, and would love a quick explanation of how this may have played a role in speeding up my procedural terrain. Any info/advice about CPU/GPU/shaders would be awesome!

  • RPi and Java Embedded GPIO: Using Java to read input

    - by hinkmond
    Now that we've learned about using Java code to control the output of the Raspberry Pi GPIO ports (by lighting up LEDs from a Java app on the RPi for now and noting in the future the same Java code can be used to drive industrial automation or medical equipment, etc.), let's move on to learn about reading input from the RPi GPIO using Java code. As before, we need to start out with the necessary hardware. For this exercise we will connect a Static Electricity Detector to the RPi GPIO port and read the value of that sensor using Java code. The circuit we'll use is from William J. Beaty and is described at this Web link. See: Static Electricity Detector He calls it an "Electric Charge" detector, which is a bit misleading. A Field Effect Transistor is subject to nearby electro-magnetic fields, such as a static charge on a nearby object, not really an electric charge. So, this sensor will detect static electricity (or ghosts if you are into paranormal activity ). Take a look at the circuit and in the next blog posts we'll step through how to connect it to the GPIO port of your RPi and then how to write Java code to access this fun sensor. Hinkmond

  • installing ubuntu on SSD

    - by kunal
    Going to install Ubuntu 10.10 on new intel x25M 80GB SSD. It will be fresh install. I have been googling for past few days and getting overwhelming articles/blogs/Q&As. One particularly very useful being: Optimize for SSD (I could not post other links as i dont have enough credits) But with so many suggestions and differences of opinions (on different links) this simple OS install process seems to be daunting task to me and I really want to stick with ubuntu (although have used for very short period of time). Can someone help me by answering few questions (yes they are repeated as i couldnt comprehend the answers elsewhere) which file system (ext2/3/4 or something else)? (consider SSD life) can it be changed after installation? should i partition the disk? (as we do in traditional HDD) for now, no plan of dual booting. Only ubuntu will live on scarce space of 80GB SSD. i have 2 GB RAM, should i still allocate swap space (if i dont allocate swap space, can i still hibernate the machine)? will swap space impact SSD life? should i consider putting additional 1GB RAM to avoid swap space? Linux experience - absolute novice intended usage - heavy browsing, programming, regular video/music and some other non-CPU/RAM-intensive programs. will backup big files to an external hard drive. laptop config - 3 yr old vaio, core2 duo, 2GB RAM Please pardon the repetition and i really appreciate anyone helping me getting started with ubuntu.

  • Language parsing to find important words

    - by Matt Huggins
    I'm looking for some input and theory on how to approach a lexical topic. Let's say I have a collection of strings, which may just be one sentence or potentially multiple sentences. I'd like to parse these strings to and rip out the most important words, perhaps with a score that denotes how likely the word is to be important. Let's look at a few examples of what I mean. Example #1: "I really want a Keurig, but I can't afford one!" This is a very basic example, just one sentence. As a human, I can easily see that "Keurig" is the most important word here. Also, "afford" is relatively important, though it's clearly not the primary point of the sentence. The word "I" appears twice, but it is not important at all since it doesn't really tell us any information. I might expect to see a hash of word/scores something like this: "Keurig" => 0.9 "afford" => 0.4 "want" => 0.2 "really" => 0.1 etc... Example #2: "Just had one of the best swimming practices of my life. Hopefully I can maintain my times come the competition. If only I had remembered to take of my non-waterproof watch." This example has multiple sentences, so there will be more important words throughout. Without repeating the point exercise from example #1, I would probably expect to see two or three really important words come out of this: "swimming" (or "swimming practice"), "competition", & "watch" (or "waterproof watch" or "non-waterproof watch" depending on how the hyphen is handled). Given a couple examples like this, how would you go about doing something similar? Are there any existing (open source) libraries or algorithms in programming that already do this?

  • Read On Phone Pushes Data from Your Desktop to the Appropriate Android App

    - by ETC
    Read On Phone is a free Android application that intelligently pushes data to your phone from your bowser. Rather than simply opening the URL on your phone, it opens the appropriate application for the task and formats text. Most send-to-phone type tools simply take the URL of the web page you’re looking at on your computer and shuttle it to your phone. Read On Phone is a more active and effective tool. When you send a page that is text, it formats the text for easy reading on your phone. When you send a YouTube video, map, or telephone number, it opens up the appropriate tool on your phone such as your YouTube viewer, Google Maps, or your phone dialer. In addition to that handy functionality Read On Phone also includes adjustments for day and night reading, font size, auto-scrolling, and pagination. Read On Phone is available as both a Chrome extension and as a bookmarklet for cross-browser use. Hit up the link below for additional information.

  • cygwin GNU make .net program piping inconsistent behavior

    - by Codism
    This question may sound like a superuser question but I feel there is something related to programming. Anyway, my computer had a fresh installation of Win 7 64 and cygwin recently. Now I observed some problem with pipe handling in gnu make file. The following is the Makefile I use to reproduce the issue: all: fsutil | cat my-dotnet-console.exe | cat The problem is: for the first command line, the piping works every time but for the second command line, the piping barely works - I got no result for the second command for most cases, regardless of the environment (cmd or bash) in which the make file is invoked. However, if I copy paste the second command line into cmd (or bash), the pipe works every time. The following is my .net program: static void Main(string[] args) { Console.WriteLine(new string('a', 40)); Console.Out.Flush(); } The make version is 3.82.90 but the same problem was observed in a previous version (because of the windows path handling problem in 3.82.9, I replaced make.exe with a previous version). I don't know the exact cygwin version I have installed but the current version on cygwin.com is 1.7.11-1. Currently, my work around is to redirect the output to a temporary file but it would be great if I can avoid the temporary file. Thanks

  • 12.04 No Sound - ALC888 / Radeon 3200HD

    - by Ross
    Evening all. I have a MSI U230 netbook, MV40 processor, 4Gb RAM with integrated ATI Radeon 3200HD grahics & an ALC888 codec integrated soundcard. It has HDMI out as well. I've tried a few distro's and have been around linux for a short time. I reckon I've settled on Ubuntu 12.04 (32bit) due to it doing pretty much everything I want it to. I'm working with a fresh install right now. I recently re-installed when I was going in circles trying to solve my problem before. I install Ubuntu and it works, except for the sound. I have tried things like reinstalling Alsa, editing my asound.conf file, installing HDA Verb and a few other things. Its at the point where I need to ask for help... Some outputs: ross@ross:~$ aplay -l ** List of PLAYBACK Hardware Devices ** card 0: SB [HDA ATI SB], device 0: ALC888 Analog [ALC888 Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: HDMI [HDA ATI HDMI], device 3: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0 ross@ross:~$ uname -r 3.2.0-34-generic-pae ross@ross:~$ lspci | grep VGA 01:05.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RS780M/RS780MN [Mobility Radeon HD 3200 Graphics] ross@ross:~$ lspci | grep Audio 00:14.2 Audio device: Advanced Micro Devices [AMD] nee ATI SBx00 Azalia (Intel HDA) 01:05.1 Audio device: Advanced Micro Devices [AMD] nee ATI RS780 HDMI Audio [Radeon HD 3000-3300 Series] Added options snd-hda-intel position_fix=1 to alsa-base.conf file Unmuted all in alsamixer Can anyone suggest anything more?

  • Woman Is the World's First Computer Programmer? [closed]

    - by Sveta Bondarenko
    This week, on 10th December, we celebrate the 197th birth anniversary of Ada Lovelace, often considered as the world's first computer programmer. Ada became famous not only as a daughter of romantic poet Lord Byron but also as an outstanding 19th century mathematician. Her works on analytical engine are recognized as the first algorithm intended to be processed by a machine. Women always played a crucial role in the computer science evolution, but unfortunately, they are considered to be not so good at programming and engineering as men. Even though the fair sex makes up a growing portion of computer and Internet users, there is still a large gender gap in the field of Computer Science. But all is not lost! According to the study women's enrollment in the computer science raised from 7 percent in 1995 to 42 percent in 2000. And it is still increasing. Soon women will take a well-deserved position among the world's top computer programmers. After all, a number of notable female computer pioneers such as Ada Lovelace, Grace Hopper, and Anita Borg have proven that women make great computer scientists. But will women make great contributions to the modern technologies industry? Or successful and famous female computer programmer is just a pipe dream?

  • Visual Studio 2010 on Macbook Air

    - by Kyle B.
    Does anyone here run Visual Studio 2010 (or VS12 RC) on a Macbook Air? I have the current model with 4GB ram, 13" screen, and 256GB SSD drive. Before I go through the effort of configuring this, I'd like to know if anyone from the community has done this and: Was the performance acceptable? If it is, I plan to get a larger cinema display monitor as a second display and do all my coding on this machine ditching my desktop. Did you use Boot camp, Parallels, or VMWare? I feel to maximize performance that boot camp would be necessary to make the most utilization of the memory, but am not sure if this completely necessary. I'd prefer to use a VM, but wasn't sure if this was practical and would value your input before buying a license. Did you also run anything else on the Windows installation, such as SQL Server express, IISExpress, etc? Did performance lag after a certain point? Note: I would have asked this in superuser.com, but felt this applied more directly to the programming community.

  • Long term plan of attack to learn math?

    - by zhenka
    I am a web-developer with a desire to expand my skill-set to mathematics relevant to programming. As 2nd career, I am stuck in college doing some of the requirements while working. I was hoping the my education will teach me the needed skills to apply math, however I am quickly finding it to be too much easily-testable breadth-based approach very inefficient for the time invested. For example in my calculus 2 class, the only remotely useful mind expanding experience I had was volumes and areas under the curve. The rest was just monotonous glorified algebra, which while comes easy to me, could be done by software like wolfram alpha within seconds. This is not my idea of learning math. So here I am a frustrated student looking for a way to improve my understanding of math in a way that focuses on application, understanding and maximally removed needless tedium. However I cannot find a good long term study strategy with this approach in mind. So for those of like mind, how would you go about learning the necessary math without worrying too much about stuff a computer can do much better?

  • Whats the greatest most impressive programing feat you ever witnessed? [closed]

    - by David Reis
    Everyone knows of the old adage that the best programmers can be orders of magnitude better than the average. I've personally seen good code and programmers, but never something so absurd. So the questions is, what is the most impressive feat of programming you ever witnessed or heard of? You can define impressive by: The scope of the task at hand e.g. John single handedly developed the framework for his company, a work comparable in scope to what the other 200 employed were doing combined. Speed e.g. Stu programmed an entire real time multi-tasking app OS on an weekened including its own C compiler and shell command line tools Complexity e.g. Jane rearchitected our entire 10 millon LOC app to work in a cluster of servers. And she did it in an afternoon. Quality e.g. Charles's code had a rate of defects per LOC 100 times lesser than the company average. Furthermore he code was clean and understandable by all. Obviously, the more of these characteristics combined, and the more extreme each of them, the more impressive is the feat. So, let me have it. What's the most absurd feat you can recount? Please provide as much detail as possible and try to avoid urban legends or exaggerations. Post only what you can actually vouch for. Bonus questions: Was the herculean task a one-of, or did the individual regularly amazed people? How do you explain such impressive performance? How was the programmer recognized for such awesome work?

  • Changes to the LINQ-to-StreamInsight Dialect

    - by Roman Schindlauer
    In previous versions of StreamInsight (1.0 through 2.0), CepStream<> represents temporal streams of many varieties: Streams with ‘open’ inputs (e.g., those defined and composed over CepStream<T>.Create(string streamName) Streams with ‘partially bound’ inputs (e.g., those defined and composed over CepStream<T>.Create(Type adapterFactory, …)) Streams with fully bound inputs (e.g., those defined and composed over To*Stream – sequences or DQC) The stream may be embedded (where Server.Create is used) The stream may be remote (where Server.Connect is used) When adding support for new programming primitives in StreamInsight 2.1, we faced a choice: Add a fourth variety (use CepStream<> to represent streams that are bound the new programming model constructs), or introduce a separate type that represents temporal streams in the new user model. We opted for the latter. Introducing a new type has the effect of reducing the number of (confusing) runtime failures due to inappropriate uses of CepStream<> instances in the incorrect context. The new types are: IStreamable<>, which logically represents a temporal stream. IQStreamable<> : IStreamable<>, which represents a queryable temporal stream. Its relationship to IStreamable<> is analogous to the relationship of IQueryable<> to IEnumerable<>. The developer can compose temporal queries over remote stream sources using this type. The syntax of temporal queries composed over IQStreamable<> is mostly consistent with the syntax of our existing CepStream<>-based LINQ provider. However, we have taken the opportunity to refine certain aspects of the language surface. Differences are outlined below. Because 2.1 introduces new types to represent temporal queries, the changes outlined in this post do no impact existing StreamInsight applications using the existing types! SelectMany StreamInsight does not support the SelectMany operator in its usual form (which is analogous to SQL’s “CROSS APPLY” operator): static IEnumerable<R> SelectMany<T, R>(this IEnumerable<T> source, Func<T, IEnumerable<R>> collectionSelector) It instead uses SelectMany as a convenient syntactic representation of an inner join. The parameter to the selector function is thus unavailable. Because the parameter isn’t supported, its type in StreamInsight 1.0 – 2.0 wasn’t carefully scrutinized. Unfortunately, the type chosen for the parameter is nonsensical to LINQ programmers: static CepStream<R> SelectMany<T, R>(this CepStream<T> source, Expression<Func<CepStream<T>, CepStream<R>>> streamSelector) Using Unit as the type for the parameter accurately reflects the StreamInsight’s capabilities: static IQStreamable<R> SelectMany<T, R>(this IQStreamable<T> source, Expression<Func<Unit, IQStreamable<R>>> streamSelector) For queries that succeed – that is, queries that do not reference the stream selector parameter – there is no difference between the code written for the two overloads: from x in xs from y in ys select f(x, y) Top-K The Take operator used in StreamInsight causes confusion for LINQ programmers because it is applied to the (unbounded) stream rather than the (bounded) window, suggesting that the query as a whole will return k rows: (from win in xs.SnapshotWindow() from x in win orderby x.A select x.B).Take(k) The use of SelectMany is also unfortunate in this context because it implies the availability of the window parameter within the remainder of the comprehension. The following compiles but fails at runtime: (from win in xs.SnapshotWindow() from x in win orderby x.A select win).Take(k) The Take operator in 2.1 is applied to the window rather than the stream: Before After (from win in xs.SnapshotWindow() from x in win orderby x.A select x.B).Take(k) from win in xs.SnapshotWindow() from b in     (from x in win     orderby x.A     select x.B).Take(k) select b Multicast We are introducing an explicit multicast operator in order to preserve expression identity, which is important given the semantics about moving code to and from StreamInsight. This also better matches existing LINQ dialects, such as Reactive. This pattern enables expressing multicasting in two ways: Implicit Explicit var ys = from x in xs          where x.A > 1          select x; var zs = from y1 in ys          from y2 in ys.ShiftEventTime(_ => TimeSpan.FromSeconds(1))          select y1 + y2; var ys = from x in xs          where x.A > 1          select x; var zs = ys.Multicast(ys1 =>     from y1 in ys1     from y2 in ys1.ShiftEventTime(_ => TimeSpan.FromSeconds(1))     select y1 + y2; Notice the product translates an expression using implicit multicast into an expression using the explicit multicast operator. The user does not see this translation. Default window policies Only default window policies are supported in the new surface. Other policies can be simulated by using AlterEventLifetime. Before After xs.SnapshotWindow(     WindowInputPolicy.ClipToWindow,     SnapshotWindowInputPolicy.Clip) xs.SnapshotWindow() xs.TumblingWindow(     TimeSpan.FromSeconds(1),     HoppingWindowOutputPolicy.PointAlignToWindowEnd) xs.TumblingWindow(     TimeSpan.FromSeconds(1)) xs.TumblingWindow(     TimeSpan.FromSeconds(1),     HoppingWindowOutputPolicy.ClipToWindowEnd) Not supported … LeftAntiJoin Representation of LASJ as a correlated sub-query in the LINQ surface is problematic as the StreamInsight engine does not support correlated sub-queries (see discussion of SelectMany). The current syntax requires the introduction of an otherwise unsupported ‘IsEmpty()’ operator. As a result, the pattern is not discoverable and implies capabilities not present in the server. The direct representation of LASJ is used instead: Before After from x in xs where     (from y in ys     where x.A > y.B     select y).IsEmpty() select x xs.LeftAntiJoin(ys, (x, y) => x.A > y.B) from x in xs where     (from y in ys     where x.A == y.B     select y).IsEmpty() select x xs.LeftAntiJoin(ys, x => x.A, y => y.B) ApplyWithUnion The ApplyWithUnion methods have been deprecated since their signatures are redundant given the standard SelectMany overloads: Before After xs.GroupBy(x => x.A).ApplyWithUnion(gs => from win in gs.SnapshotWindow() select win.Count()) xs.GroupBy(x => x.A).SelectMany(     gs =>     from win in gs.SnapshotWindow()     select win.Count()) xs.GroupBy(x => x.A).ApplyWithUnion(gs => from win in gs.SnapshotWindow() select win.Count(), r => new { r.Key, Count = r.Payload }) from x in xs group x by x.A into gs from win in gs.SnapshotWindow() select new { gs.Key, Count = win.Count() } Alternate UDO syntax The representation of UDOs in the StreamInsight LINQ dialect confuses cardinalities. Based on the semantics of user-defined operators in StreamInsight, one would expect to construct queries in the following form: from win in xs.SnapshotWindow() from y in MyUdo(win) select y Instead, the UDO proxy method is referenced within a projection, and the (many) results returned by the user code are automatically flattened into a stream: from win in xs.SnapshotWindow() select MyUdo(win) The “many-or-one” confusion is exemplified by the following example that compiles but fails at runtime: from win in xs.SnapshotWindow() select MyUdo(win) + win.Count() The above query must fail because the UDO is in fact returning many values per window while the count aggregate is returning one. Original syntax New alternate syntax from win in xs.SnapshotWindow() select win.UdoProxy(1) from win in xs.SnapshotWindow() from y in win.UserDefinedOperator(() => new Udo(1)) select y -or- from win in xs.SnapshotWindow() from y in win.UdoMacro(1) select y Notice that this formulation also sidesteps the dynamic type pitfalls of the existing “proxy method” approach to UDOs, in which the type of the UDO implementation (TInput, TOuput) and the type of its constructor arguments (TConfig) need to align in a precise and non-obvious way with the argument and return types for the corresponding proxy method. UDSO syntax UDSO currently leverages the DataContractSerializer to clone initial state for logical instances of the user operator. Initial state will instead be described by an expression in the new LINQ surface. Before After xs.Scan(new Udso()) xs.Scan(() => new Udso()) Name changes ShiftEventTime => AlterEventStartTime: The alter event lifetime overload taking a new start time value has been renamed. CountByStartTimeWindow => CountWindow

  • Using XSLT for messaging instead of marshalling/unmarshalling Java message objects

    - by Joost van Stuijvenberg
    So far I have been using either handmade or generated (e.g. JAXB) Java objects as 'carriers' for messages in message processing software such as protocol converters. This often leads to tedious programming, such as copying/converting data from one system's message object to an instance of another's system message object. And it sure brings in lots of Java code with getters and setters for each message attribute, validation code, etc. I was wondering whether it would be a good idea to convert one system's XML message into another system's format - or even convert requests into responses from the same system - using XSLT. This would mean I would no longer have to unmarshall XML streams to Java objects, copy/convert data using Java and marshall the resulting message object to another XML stream. Since each message may actually have a purpose I would 'link' the message (and the payload it contains in its properties or XML elements/attributes) to EXSLT functions. This would change my design approach from an imperative to a declarative style. Has anyone done this before and, if so, what are your experiences? Does the reduced amount of Java 'boiler plate' code weigh up to the increased complexity of (E)XSLT?

  • JEE frameworks, a road map to learn? and should I learn them?

    - by vibhor
    Background Information I have been into programming since past 1 years professionally, my day to day work includes writing BIRT reports, designing and validating forms using JEE (struts/spring, hibernate). I don't have a comp Sci 4 year degree (Electronics), so I have very Limited experience in comp Sci. Question JEE frameworks (struts1/2, spring, hibernate etc) are hot nowadays, however java world have a tendency of building A4j, B4J... mayway4J kind of stuff (and I am tired of it). AFAIK, frameworks are nothing but bunch of XML config files and hundreds of classes built to cram (by developer). And sooner then later a new framework come into picture that says I am the best among all. So My Question is - 1.What will you do to learn a framework (many frameworks) considering that it can be obsolete till you'll be master in it (Learning frameworks can take significant amount of time)? 2.Considering early into your career, will you give a damn that how well someone knows framework (knowing frame work is important but still..) and why/how should I learn a framework knowing I have to (un)learn it in order to learn other one (plenty of of 4Js....)? I am just trying to get a big picture, that, if you're in place of me, what would be your learning/cramming strategy (Road map)? I am not intended to start a holy war between A versus B, (frameworks are more or less essential).

  • Comparing the Performance of Visual Studio's Web Reference to a Custom Class

    As developers, we all make assumptions when programming. Perhaps the biggest assumption we make is that those libraries and tools that ship with the .NET Framework are the best way to accomplish a given task. For example, most developers assume that using ASP.NET's Membership system is the best way to manage user accounts in a website (rather than rolling your own user account store). Similarly, creating a Web Reference to communicate with a web service generates markup that auto-creates a proxy class, which handles the low-level details of invoking the web service, serializing parameters, and so on. Recently a client made us question one of our fundamental assumptions about the .NET Framework and Web Services by asking, "Why should we use proxy class created by Visual Studio to connect to a web service?" In this particular project we were calling a web service to retrieve data, which was then sorted, formatted slightly and displayed in a web page. The client hypothesized that it would be more efficient to invoke the web service directly via the HttpWebRequest class, retrieve the XML output, populate an XmlDocument object, then use XSLT to output the result to HTML. Surely that would be faster than using Visual Studio's auto-generated proxy class, right? Prior to this request, we had never considered rolling our own proxy class; we had always taken advantage of the proxy classes Visual Studio auto-generated for us. Could these auto-generated proxy classes be inefficient? Would retrieving and parsing the web service's XML directly be more efficient? The only way to know for sure was to test my client's hypothesis. Read More >

  • Game Trees Conceptual Question

    - by Chris Corbin
    I am struggling to conceptually understand a question in a programming assignment for an algorithms class. The problem is dealing with a fictitious 2 player game, named Easy. The rules of the game are simple; each player may chose one of 4 integers {0-3} after which that integer is not available for the other player. The catch is, a player picks {0} it means they quit. The objective is for Player 1 to get {1} and Player 2 to get {2}, in which case they may win, however if both or neither succeed, then the game ends in a draw. I have been asked to draw the game tree for Easy, showing all nodes, which they explained as 4! = 24. Labeling the edges, which represent moves (selecting a number) and the leaves with who won (1 means Player 1 won, -1 means Player 2 won, and 0 means a tie). I have drawn out a game tree, which I believe is correct, however I am not 100% certain hence I am asking the question. My game tree only has 16 leaves. I am thinking that when a player picks {0}, and then quits, the game tree stops there? I don't see how it is possible to get to 24 leaves? Any help would be greatly appreciate, and if you need more information I would be happy to provide it. Thanks

  • Presenting the Cloud in a Different Way

    - by BuckWoody
    I had the honor of presenting the Developers at the Portland PASS chapter, and decided to go a different way than just using PowerPoint Slides…. (click on any picture to enlarge) The point is that when you need to get a point across, it’s OK to change tactics to make sure the information sticks. In this case, I decided to make the audience the PowerPoint. I used a few props to show the various paradigms we use to describe what the industry uses for the word “cloud” First, we talked about Infrastructure as a Service. I picked a gentleman who didn’t quite fit the hard hat and safety vest I picked out for him. Notice our “user” as she accesses our “Server” (complete with tray and glass) which has been virtualized.    Software as a service comes next. In this case, the user and potentially even customers just access software (represented here as a Windows ME box…) remotely – everything is virtualized. Finally, Platform as a Service – Yup, Platform shoes as a necklace, and a tie-dye shirt to represent the 70’s – a decade when mainframes used stateless programming as well. Notice also the components of Windows Azure – Compute (Keyboard) Application Fabric (Toy Bus) and Storage (Bucket).   And at the end of the day, it’s all about serving those customers…
