  • Representation of data in application versus database

    - by user1815201
    I'm going to make an application that will be given data to put in a database. The data will for the most part be the same, but the way it is formatted will vary a lot (could be in anything from text files to .xls to .doc). I'm not a very experienced developer, but I can see some potential issues and I want to minimize them. First off I have decided to use the DAO pattern, so that I can easily support new file formats or file suddenly formatted in different ways. What I really wonder about though, is how I should manage the data itself within my application. I'm thinking that the database DAO should have models representing each table of the database with the same relations between them, to make the uploading process easy. But should the filesystem DAO's have to use the same models? I can imaging that when the database changes, the change will suddenly propagate throughout the entire system, all DAOs and models alike. And that is obviously a bad thing. I'm a little bit tired and out of time. Will update with what ever questions you have. Thanks!

  • My Thoughts on Reinventing the Wheel

    - by Matt Christian
    For awhile now I've known that XNA Game Studio contains built-in scene management however I still built my own for each engine.  Obviously it was redundant and probably inefficient due to the amount of searching and such I was required to do.  And even though I knew this, why did I continue to do it? I've always been very detail oriented, probably part of my mild OCD.  But when it comes to technology I believe in both reinventing the wheel and not reinventing it all at the same time.  Here's what I imagine most programmers doing.  When they pick up XNA, they're typically focused on 'I want to make a game with as little code as possible'.  This is great and XNA GS is a great tool, but what will it do for programmers that want to make games with XNA?  If they don't have any prior experience with other tools they will probably not ever learn scene management. So is it better to leverage code and risk not learning valuable techniques, or write it all yourself and fight through the headaches and hours of time you may spend on something already built?

  • Questions about Mac Book Pro Keyboard and shortcuts

    - by SimonSolnes
    I have been researching a lot about this and I cannot seem to find any useful information about this topic, what so ever. I have now been using Ubuntu in one week, and have gotten pretty confident with almost everything. Except keyboard layout and shortcuts. If you know a tutorial or a documents explaining keyboard shortcuts in Ubuntu or linux in general, can you please list it? I use a Mac Book Pro with a Norwegian keyboard, and I have several questions about this: Is there a program for having a consise list of absolutely all keyboard shortcuts, and be able to change them? How do I use my fn keys? (fn button doesnt do the job for some reason) How can I use my alt+letter-key-or-number-key or alt+shift+letter-key-or-number-key to get fancy characters. (Like I do on Mac OS X) How can I swap cmd and ctrl key system wide? Also I really want to be oriented around this subject, since this is the only thing holding me back on Ubuntu, so if there exists some in-depth material on this, it would be great. Also, if there exists some programs or material out there making it easier with Mac hardware I would enjoy that. Sorry if my questions seems vague. Thank you very much Simon

  • Duck checker in Python: does one exist?

    - by elliot42
    Python uses duck-typing, rather than static type checking. But many of the same concerns ultimately apply: does an object have the desired methods and attributes? Do those attributes have valid, in-range values? Whether you're writing constraints in code, or writing test cases, or validating user input, or just debugging, inevitably somewhere you'll need to verify that an object is still in a proper state--that it still "looks like a duck" and "quacks like a duck." In statically typed languages you can simply declare "int x", and anytime you create or mutate x, it will always be a valid int. It seems feasible to decorate a Python object to ensure that it is valid under certain constraints, and that every time that object is mutated it is still valid under those constraints. Ideally there would be a simple declarative syntax to express "hasattr length and length is non-negative" (not in those words. Not unlike Rails validators, but less human-language and more programming-language). You could think of this as ad-hoc interface/type system, or you could think of it as an ever-present object-level unit test. Does such a library exist to declare and validate constraint/duck-checking on Python-objects? Is this an unreasonable tool to want? :) (Thanks!) Contrived example: rectangle = {'length': 5, 'width': 10} # We live in a fictional universe where multiplication is super expensive. # Therefore any time we multiply, we need to cache the results. def area(rect): if 'area' in rect: return rect['area'] rect['area'] = rect['length'] * rect['width'] return rect['area'] print area(rectangle) rectangle['length'] = 15 print area(rectangle) # compare expected vs. actual output! # imagine the same thing with object attributes rather than dictionary keys.

  • Dapper and object validation/business rules enforcement

    - by Eugene
    This isn't really Dapper-specific, actually, as it relates to any XML-serializeable object.. but it came up when I was storing an object using Dapper. Anyways, say I have a user class. Normally, I'd do something like this: class User { public string SIN {get; private set;} public string DisplayName {get;set;} public User(string sin) { if (string.IsNullOrWhiteSpace(sin)) throw new ArgumentException("SIN must be specified"); this.SIN = sin; } } Since a SIN is required, I'd just create a constructor with a sin parameter, and make it read-only. However, with a Dapper (and probably any other ORM), I need to provide a parameterless constructor, and make all properties writeable. So now I have this: class User: IValidatableObject { public int Id { get; set; } public string SIN { get; set; } public string DisplayName { get; set; } public IEnumerable<ValidationResult> Validate(ValidationContext validationContext) { // implementation } } This seems.. can't really pick the word, a bad smell? A) I'm allowing to change properties that should not be changed ever after an object has been created (SIN, userid) B) Now I have to implement IValidatableObject or something like that to test those properties before updating them to db. So how do you go about it ?

  • Bypass Facebook Social Reader Apps using Google Chrome Extension

    - by Gopinath
    One of the most annoying features of Facebook  is it’s Social Reader Apps that share automatically whatever your read, watch or listen online.  I don’t like to share what ever I do online to Facebook as I want my privacy. Few of  my friends knowingly or unknowingly are using Social Reader apps and their online activity is automatically posted to the wall. To read these articles or watch videos shared by Social Reader application I need to add the application and allow it to automatically post. I don’t like Social Reader Apps and if you are one like me, here is a Google Chrome browser plugin that allows us to bypass Social Reader Apps. The extension Facebook Unsocial Reader smartly rewrites Facebook links in such a way that you will be able to access content of links without adding Social Reader Apps to your account. To rewrite the links, the extension cleverly uses Google I’m Feeling Lucky service and searches for the article’s title. The first search result of Google is almost perfect in identifying the original article link. If you are a heavy Facebook user and concerned about using Social Reader Apps, this plugin is must to have. Photo (cc) Josh Hallett. Facebook Unsocial Reader Extension for Google Chrome

  • Compiz not drawing window controls in ubuntu 11.10

    - by Siva Prasad Varma
    I have recently installed driver for my ATI graphic card in my Dell Studio laptop. I have also read this somewhere on the web that Ubuntu enables compiz window manager by default if your hardware can run it. Is it true ? In my case before Installing graphic card driver the window manager was Metacity, but now I have compiz as my Window manager. I found this out uisng Displex Indicator applet also confirmed by wmctrl -m. From the time I have installed graphic card drivers, the window manager(Compiz) is not drawing window control buttons for some of the windows. For example if I open a terminal I have to close it using key board shortcuts or use the File - Quit option in app-menu. Also I am not able to move the window because of this. From then when-ever I find a window without window control buttons I am restarting the window manager using Displex Indicator applet. But this is very annoying and also consumes a lot of time(when I am doing my work). Can any one suggest any solution for this. What are up's and down's of using Compiz Vs Metacity.

  • Visual WebGui helps Dawsons put its Windows Forms HR system on the web

    - by Webgui
    Dawsons needed to upgrade their existing Windows Forms LAN human resources system to allow better and flexible access to the ever increasing data size as labor hire clients are demanding easy access to copies of tickets and licenses and etc. The company has some 30,000 applicants on file, but access to this data has been complex and limited with the current system. Therefore the IT department was asked to find a possible solutions that would allow creating a web based application while utilizing as much of the existing Windows Forms code as possible. Visual WebGui was found to be highly regarded in many frameworks comparisons so the team decided to give Visual WebGui a try. It didn’t take long for them to recognize that the Visual WebGui controls appear and react over the web the same as desktop controls. This and the fact that most of the code was directly ported which saved Dawsons hundreds of development hours are what make Visual WebGui so unique and productive. “My first impression of Visual WebGui was perhaps disbelief. Not being a seasoned Web programmer, I initially found it hard to accept so much functionality from a web based application. Also, the speed is exceptional” said John Sainsbury, Financial Controller of the Dawsons Group who added “Since working with Visual WebGui, I have showcased parts of the application to our major clients, some of whom use SAP portals, and they are amazed.” The result was so satisfying that the company is now looking to produce a mobile version for accessing the labor pool on the go. “By removing the barriers of the local network, Visual WebGui has changed how we can do business” said Lloyd Everist, General Manager Dawsons Group.

  • Calculate the Intersection of Two Volumes

    - by igrad
    If you've ever played The Swapper, you'll have a good idea of what I'm asking about. I need to check for, and isolate, areas of a rectangle that may intersect with either a circle or another rectangle. These selected areas will receive special properties, and the areas will be non-static, since the intersecting shapes themselves will also be dynamic. My first thought was to use raycasting detection, though I've only seen that in use with circles, or even ellipses. I'm curious if there's a method of using raycasting with a more rectangular approach, or if there's a totally different method already in use to accomplish this task. I would like something more exact than checking in large chunks, and since I'm using SDL2 with a logical renderer size of 1920x1080, checking if each pixel is intersecting is out of the question, as it would slow things down past a playable speed. I already have a multi-shape collision function-template in place, and I could use that, though it only checks if sides or corners are intersecting; it does not compute the overlapping area, or even find the circle's secant line, though I can't imagine it would be overly complex to implement. TL;DR: I need to find and isolate areas of a rectangle that may intersect with a circle or another rectangle without checking every single pixel on-screen.

  • Windows 8 + Ubuntu dualboot problem - ubuntu does not load after windows updates

    - by Michal Biros
    I have installed Windows 8 64-bit and Ubuntu 14.04 64-bit in dualboot with EFI mode. Everything worked great. I could run Ubuntu or Windows without any problems. Only one little issue was that Windows locked NTFS partitions when I shut it down. When I clicked on restart button in Windows and started Ubuntu, partitions mounted successfully. But today ... I opened windows and downloaded all available updates. When I wanted to come back to Ubuntu I noticed that grub did not count down seconds to automatic start. After choosing Ubuntu option manually, the OS did not load. Just black screen with white underscore in the upper left corner. Windows is accessible always without such issues. Last time I solved it by reinstalling ubuntu but I dont want to do it each time windows downloads some updates. Have you ever meet such problem, or do you know how to solve it? EDIT Ubuntu boots, but it won't start. It ends on loading screen.

  • Is It Time To Specialize?

    - by Tim Murphy
    Originally posted on: http://geekswithblogs.net/tmurphy/archive/2013/06/18/is-it-time-to-specialize.aspx Over my career I have made a living as a generalist.  I have been a jack of all trades and a master of none.  It has served me well in that I am able to move from one technology to the other quickly and make myself productive.  Where it becomes a problem is deep knowledge.  I am constantly digging for the things that aren’t basic knowledge.  How do you make a product like WCF or Windows RT do more than just “Hello World”? As an architect I need to be a jack of all trades.  This is what helps me to bring the big picture of a project into focus for developers with different skills to accomplish the goals of the project. It is a key when the mix technologies crosses Windows, Unix and Mainframe with different languages and databases.  The larger the company that the project is for the more likely this scenario will arise. As a consultant and a developer I need to have specialized skills in order to get the job done efficiently.  if I have a SharePoint or Windows Phone project knowing the object model details and possible roadblocks of the technology allow me to stay within budgets as well as better advise the client on technology decisions. What is the solution?  Constant learning and associating with developers who specialize in a variety of technologies is the best thing you can do.  You may have thought you were done with classes when you left college, but in this industry you need to constantly be learning new products and languages.  The ultimate answer is you must generally specialize.  Learn as many subject areas as possible, but go deep when ever you can.  Sleep is overrated.  Good luck. del.icio.us Tags: software development,software architecture,specialization,generalist

  • C# XNA: Effecient mesh building algorithm for voxel based terrain ("top" outside layer only, non-destructible)

    - by Tim Hatch
    To put this bluntly, for non-destructible/non-constructible voxel style terrain, are generated meshes handled much better than instancing? Is there another method to achieve millions of visible quad faces per scene with ease? If generated meshes per chunk is the way to go, what kind of algorithm might I want to use based on only EVER needing the outer layer rendered? I'm using 3D Perlin Noise for terrain generation (for overhangs/caves/etc). The layout is fantastic, but even for around 20k visible faces, it's quite slow using instancing (whether it's one big draw call or multiple smaller chunks). I've simplified it to the point of removing non-visible cubes and only having the top faces of my cube-like terrain be rendered, but with 20k quad instances, it's still pretty sluggish (30fps on my machine). My goal is for the world to be made using quite small cubes. Where multiple games (IE: Minecraft) have the player 1x1 cube in width/length and 2 high, I'm shooting for 6x6 width/length and 9 high. With a lot of advantages as far as gameplay goes, it also means I could quite easily have a single scene with millions of truly visible quads. So, I have been trying to look into changing my method from instancing to mesh generation on a chunk by chunk basis. Do video cards handle this type of processing better than separate quads/cubes through instancing? What kind of existing algorithms should I be looking into? I've seen references to marching cubes a few times now, but I haven't spent much time investigating it since I don't know if it's the better route for my situation or not. I'm also starting to doubt my need of using 3D Perlin noise for terrain generation since I won't want the kind of depth it would seem best at. I just like the idea of overhangs and occasional cave-like structures, but could find no better 'surface only' algorithms to cover that. If anyone has any better suggestions there, feel free to throw them at me too. Thanks, Mythics

  • Start Debugging in Visual Studio

    - by Daniel Moth
    Every developer is familiar with hitting F5 and debugging their application, which starts their app with the Visual Studio debugger attached from the start (instead of attaching later). This is one way to achieve step 1 of the Live Debugging process. Hitting F5, F11, Ctrl+F10 and the other ways to start the process under the debugger is covered in this MSDN "How To". The way you configure the debugging experience, before you hit F5, is by selecting the "Project" and then the "Properties" menu (Alt+F7 on my keyboard bindings). Dependent on your project type there are different options, but if you browse to the Debug (or Debugging) node in the properties page you'll have a way to select local or remote machine debugging, what debug engines to use, command line arguments to use during debugging etc. Currently the .NET and C++ project systems are different, but one would hope that one day they would be unified to use the same mechanism and UI (I don't work on that product team so I have no knowledge of whether that is a goal or if it will ever happen). Personally I like the C++ one better, here is what it looks like (and it is described on this MSDN page): If you were following along in the "Attach to Process" blog post, the equivalent to the "Select Code Type" dialog is the "Debugger Type" dropdown: that is how you change the debug engine. Some of the debugger properties options appear on the standard toolbar in VS. With Visual Studio 11, the Debug Type option has been added to the toolbar If you don't see that in your installation, customize the toolbar to show it - VS 11 tends to be conservative in what you see by default, especially for the non-C++ Visual Studio profiles. Comments about this post by Daniel Moth welcome at the original blog.

  • Red Dot Scope Makes Sighting In Long Lenses a Snap

    - by Jason Fitzpatrick
    If you’ve ever used a high power lens, you know how tricky it can be to sight a distant subject as the field of view through the lens is so tiny. This hack takes care of that problem by using a zero-magnification red dot rifle scope. Chris Malcolm enjoys photographing birds and other wildlife with high power lenses. The problem, when shooting with huge 500mm lens and other high power lenses, is that they’re practically telescopes and acquiring a fast moving target like a bird using a through-the-lens technique is very tricky. Malcolm’s solution hinges on mounting a zero-magnification red dot rifle scope in parallel with the lens. His mock up is a bit unpolished (although we can understand not wanting to run out and buy a brand new black scope just for the experiment) but works great to get him on target. Hit up the link below to read more about his build, how be created the rail mount for the scope, and why he opted to mount it to the barrel of the lens and not the hot shoe mount on the camera. 500mm Reflex Lens with Red Dot Sight [via DIY Photography] Make Your Own Windows 8 Start Button with Zero Memory Usage Reader Request: How To Repair Blurry Photos HTG Explains: What Can You Find in an Email Header?

  • 5 Ways Microsoft Can Improve the Windows 8 Start Screen

    - by Matt Klein
    After having used Windows 8 over the past few months, we’ve found a few ways Microsoft could immediately improve the Start Screen to make it less disorienting and more usable, not only for tablets but desktops and laptops as well. It’s safe to say that the one thing Windows 8 doesn’t lack is criticism. Since the Consumer Preview debuted in February, it has proven to be one of the most polarizing Windows releases ever. But regardless of whether you love or hate it, Windows 8 is where Microsoft’s venerable operating system is headed. Portable computing is here to stay and if the company is to survive, let alone remain relevant, it has to change, adapt, embrace, and extend. Perhaps the single most universally controversial change to Windows is Microsoft’s decision to remove the Start button (or orb, if you’ve moved beyond XP) and with it, what we know to be the Start Menu. In their place we now have a Start hot corner (a workable alternative) and the newly redesigned Metro Start Screen. The Start Screen is, if nothing else, different. Beyond a doubt, there has not been such a radical redesign of Windows’ Start functionality since it went to a two-column design with a nested “All Programs” menu in Windows XP. The Start Screen can be a little jarring because it requires users to not only relearn what they’ve known for nearly two decades but to also rethink the way they interact with Windows. However, the Start Screen maintains its core elements: a Start “menu”, a place for all installed programs (All apps), and a search pane. The Start Screen is attractive, clean, bold, and very imperfect. Here are five changes we’d like to see in the Start Screen before Windows 8 goes gold … How to Make Your Laptop Choose a Wired Connection Instead of Wireless HTG Explains: What Is Two-Factor Authentication and Should I Be Using It?

  • Programming as a minor

    - by Tomas Cokis
    Hello Everyone! I've never asked a question here at programmers, and for reasons which will become obvious later I've never answered one here, but I do poke around in short bursts. Anyway, I'm 15 right now, and I've been programming in C++ for 4 years, just working on my own projects that are aim so high as to never be finished. I've been working on a single project for the last year, and every 3 months, I add a new system into it. It might be a value tabling directory enabled log system, or a render system, or a class to load up xml files, whatever it is, I don't mind too much that the overall project (a 3d engine) isn't ever going to get finished, I just get some satisfaction from getting what I have done building and running. I don't know what I want to do when I grow up, although I suspect I'll go into some form of engineering, but I was interested in knowing if I do choose to go into a career as a developer, what kind of material I could look at to push myself up and get myself experience that might help my career later. I'm not talking about books in particular, I'm more interested in subjects areas that will get me access to good job opportunities, or that will give me a hand-up if I do computer science and software related courses at uni. One of the things I was thinking of doing was designing some of the logic gate components of a small computer - which I started briefly over the holidays, working out integer addition, subtraction and multiplication. That kind of stuff interests me, but is it really useful - or more useful then just more programming? But anyway, Any advice? Should I continue on my perpetual 3d engine? Are there any other projects or particular accomplishments that would help my education? Perhaps I should mention that I live in Perth, Australia, so local software companies are likely to be more scarce then usual.

    - by Jeffrey West
    I’m new to blogging.  This is the second blog post that I have written, and before I go too much further I wanted the readers of my blog to know a bit more about me… Kid’s Stuff By trade, I am a programmer (or coder, developer, engineer, architect, etc).  I started programming when I was 12 years old.  When I was 7, we got our first ‘family’ computer – an Apple IIc.  It was great to play games on, and of course what else was a 7-year-old going to do with it.  I did have one problem with it, though.  When I put in my 5.25” floppy to play a game, sometimes, instead loading my game I would get a mysterious ‘]’ on the screen with a flashing cursor.  This, of course, was not my game.  Much like the standard ‘Microsoft fix’ is to reboot, back then you would take the floppy out, shake it, and restart the computer and pray for a different result. One day, I learned at school that I could topple my nemesis – the ‘]’ and flashing cursor – by typing ‘load’ and pressing enter.  Most of the time, this would load my game and then I would get to play.  Problem solved.  However, I began to wonder – what else can I make it do? When I was in 5th grade my dad got a bright idea to buy me a Tandy 1000HX.  He didn’t know what I was going to do with it, and neither did I.  Least of all, my mom wasn’t happy about buying a 5th grader a $1,000 computer.  Nonetheless, Over time, I learned how to write simple basic programs out of the back of my Math book: 10 x=5 20 y=6 30 PRINT x+y That was fun for all of about 5 minutes.  I needed more – more challenges, more things that I could make the computer do.  In order to quench this thirst my parents sent me to National Computer Camps in Connecticut.  It was one of the best experiences of my childhood, and I spent 3 weeks each summer after that learning BASIC, Pascal, Turbo C and some C++.  There weren’t many kids at the time who knew anything about computers, and lets just say my knowledge of and interest in computers didn’t score me many ‘cool’ points.  My experiences at NCC set me on the path that I find myself on now, and I am very thankful for the experience.  Real Life I have held various positions in the past at different levels within the IT layer cake.  I started out as a Software Developer for a startup in the Dallas, TX area building software for semiconductor testing statistical process control and sampling.  I was the second Java developer that was hired, and the ninth employee overall, so I got a great deal of experience developing software.  Since there weren’t that many people in the organization, I also got a lot of field experience which meant that if I screwed up the code, I got yelled at (figuratively) by both my boss AND the customer.  Fun Times!  What made it better was that I got to help run pilot programs in Taiwan, Singapore, Malaysia and Malta.  Getting yelled at in Taiwan is slightly less annoying that getting yelled at in Dallas… I spent the next 5 years at Accenture doing systems integration in the ‘SOA’ group.  I joined as a Consultant and left as a Senior Manager.  I started out writing code in WebLogic Integration and left after I wrapped up project where I led a team of 25 to develop the next generation of a digital media platform to deliver HD content in a digital format.  At Accenture, I had the pleasure of working with some truly amazing people – mentoring some and learning from many others – and on some incredible real-world IT projects.  Given my background with the BEA stack of products I was often called in to troubleshoot and tune WebLogic, ALBPM and ALSB installations and have logged many hours digging through thread dumps, running performance tests with SoapUI and decompiling Java classes we didn’t have the source for so I could see what was going on in the code. I am now a Senior Principal Product Manager at Oracle in the Application Grid practice.  The term ‘Application Grid’ refers to a collection of software and hardware products within Oracle that enables customers to build horizontally scalable systems.  This collection of products includes WebLogic, GlassFish, Coherence, Tuxedo and the JRockit/HotSpot JVMs (HotSprocket, maybe?).  Now, with the introduction of Exalogic it has grown to include hardware as well. Wrapping it up… I love technology and have a diverse background ranging from software development to HW and network architecture & tuning.  I have held certifications for being an Oracle Certified DBA, MSCE and Cisco Certified Network Professional (CCNP), among others and I have put those to great use over my career.  I am excited about programming & technology and I enjoy helping people learn and be successful.  If you are having challenges with WebLogic, BPM or Service Bus feel free to reach out to me and I’ll be happy to help as I have time. Thanks for stopping by!   --Jeff

  • Creating reproducible builds to verify Free Software

    - by mikkykkat
    Free Software is about freedom and privacy, Open Source software is great but making that fully practical usually won't happen. Most Free Software developers publicize binaries that we can't verify are really compiled from the source code or have something bad injected already! We have the freedom to change the code, but privacy for ordinary users is missing. For desktop software there is a lot of languages and opportunities to create Free Software with a reproducible build process (compiling source code to always produce the exact same binary), but for mobile computing I don't know if same thing is possible or not? Mobile devices are probably the future of computing and Android is the only Open Source environment so far which accept Java for coding. Compiling same Android application won't result in the exact same binary every time. For Open Source Android apps how we can verify the produced binary (.apk) is really compiled from the source code? Is there any way to create reproducible builds from the Android SDK or does Java fail here for Free Software? is there any java software ever wrote with a reproducible build?

  • Stop Your Mouse from Waking Up Your Windows 7 Computer

    - by The Geek
    If you use Sleep Mode on your PC, have you ever noticed that moving your mouse will wake the computer from sleep mode? If you would prefer to only have the PC wake up when you hit a key instead, there’s a simple tweak. Just type Mouse into the start menu search box, or the Control Panel search box, and then open up the Mouse Properties panel. Find the Hardware tab, select your mouse in the list, and then click the Properties button. You’ll have to click the “Change settings” button before you can see the Power Management tab… And now, you can uncheck the box from “Allow this device to wake the computer”. That’s all there is to it.

  • Perl - can't flush STDOUT or STDERR

    - by Jim Salter
    Perl 5.14 from stock Ubuntu Precise repos. Trying to write a simple wrapper to monitor progress on copying from one stream to another: use IO::Handle; while ($bufsize = read (SOURCE, $buffer, 1048576)) { STDERR->printflush ("Transferred $xferred of $sendsize bytes\n"); $xferred += $bufsize; print TARGET $buffer; } This does not perform as expected (writing a line each time the 1M buffer is read). I end up seeing the first line (with a blank value of $xferred), and then the 7th and 8th lines (on an 8MB transfer). Been pounding my brains out on this for hours - I've read the perldocs, I've read the classic "Suffering from Buffering" article, I've tried everything from select and $|++ to IO::Handle to binmode (STDERR, "::unix") to you name it. I've also tried flushing TARGET with each line using IO::Handle (TARGET-flush). No dice. Has anybody else ever encountered this? I don't have any ideas left. Sleeping one second "fixes" the problem, but obviously I don't want to sleep a second every time I read a buffer just so my progress will output on the screen! FWIW, the problem is exactly the same whether I'm outputting to STDERR or STDOUT.
