  • #altnetseattle - Kanban

    - by GeekAgilistMercenary
    The two main concepts of Kanban is to keep the queues minimum and to maintain visibility. Management/leadership needs to make sure the Kanban Queue doesn’t get starved.  This is key and also very challenging, being the queue needs to be minimal but also can’t get too small during the course of work.  This is to maintain maximum velocity. Phases of the Kanban need to be kept flowing too, bottlenecks need removed ASAP when brought up. Victory Wall – I dig that idea.  Somewhere to look to see the success of the team. The POs work in Rally or other tools for some client management, but it causes issues with the lack of "visibility" – a key fundamental ideal & part of Kanban. One of the big issues is fitting things into a sprint, when Kanban is used with Scrum, but longer sprints are wasteful. Kanban work sizes are of a set size. At this point I got a bit side tracked by the actual conversation and missed out on note taking.  Overall, people doing Kanban and Lean Style Software Development I would say are some of the happiest coders around.  The clean focus, good velocity, sizing, and other approaches that are inferred by Kanban help developers be the rock stars and succeed. This is definitely a topic I will be commenting on a lot more in the near future.

  • Best Method of function parameter validation

    - by Aglystas
    I've been dabbling with the idea of creating my own CMS for the experience and because it would be fun to run my website off my own code base. One of the decisions I keep coming back to is how best to validate incoming parameters for functions. This is mostly in reference to simple data types since object validation would be quite a bit more complex. At first I debated creating a naming convention that would contain information about what the parameters should be, (int, string, bool, etc) then I also figured I could create options to validate against. But then in every function I still need to run some sort of parameter validation that parses the parameter name to determine what the value can be then validate against it, granted this would be handled by passing the list of parameters to function but that still needs to happen and one of my goals is to remove the parameter validation from the function itself so that you can only have the actual function code that accomplishes the intended task without the additional code for validation. Is there any good way of handling this, or is it so low level that typically parameter validation is just done at the start of the function call anyway, so I should stick with doing that.

  • How to improve Minecraft-esque voxel world performance?

    - by SomeXnaChump
    After playing Minecraft I marveled a bit at its large worlds but at the same time I found them extremely slow to navigate, even with a quad core and meaty graphics card. Now I assume Minecraft is fairly slow because: A) It's written in Java, and as most of the spatial partitioning and memory management activities happen in there, it would naturally be slower than a native C++ version. B) It doesn't partition its world very well. I could be wrong on both assumptions; however it got me thinking about the best way to manage large voxel worlds. As it is a true 3D world, where a block can exist in any part of the world, it is basically a big 3D array [x][y][z], where each block in the world has a type (i.e BlockType.Empty = 0, BlockType.Dirt = 1 etc.) Now, I am assuming to make this sort of world perform well you would need to: A) Use a tree of some variety (oct/kd/bsp) to split all the cubes out; it seems like an oct/kd would be the better option as you can just partition on a per cube level not a per triangle level. B) Use some algorithm to work out which blocks can currently be seen, as blocks closer to the user could obfuscate the blocks behind, making it pointless to render them. C) Keep the block object themselves lightweight, so it is quick to add and remove them from the trees. I guess there is no right answer to this, but I would be interested to see peoples' opinions on the subject. How would you improve performance in a large voxel-based world?

  • Motherboard memory question

    - by JERiv
    I am currently drawing up specs on a new workstation for my office. I am considering the Asus P6X58D for a motherboard. This board's specs list it as supporting 24 gigs of memory. Suppose I were to use six four gig memory cards and then two video cards with 1 gig of memory apiece. Is the maximum supported memory similar to how 32 bit operating systems only have enough address space for 4 gigs of memory? Simply: Will the board post? If so, will the system be able to address all the memory, both the 24 gigs on the ddr3 bus and the 3 gigs on the graphics card?

  • Looking at desktop virtualization, but some users need 3D support. Is HP Remote Graphics a viable solution?

    - by Ryan Thompson
    My company is looking at desktop virtualization, and are planning to move all of the desktop compute resources into the server room or data center, and provide users with thin clients for access. In most cases, a simple VNC or Remote Desktop solution is adequate, but some users are running visualizations that require 3D capability--something that VNC and Remote Desktop cannot support. Rather than making an exception and providing desktop machines for these users, complicating out rollout and future operations, we are considering adding servers with GPUs, and using HP's Remote Graphics to provide access from the thin client. The demo version appears to work acceptably, but there is a bit of a learning curve, it's not clear how well it would work for multiple simultaneous sessions, and it's not clear if it would be a good solution to apply to non-3D sessions. If possible, as with the hardware, we want to deploy a single software solution instead of a mishmash. If anyone has had experience managing a large installation of HP Remote Graphics, I would appreciate any feedback you can provide.

  • Internet Timeouts with TP-Link TL-WN821N v2 wireless usb stick

    - by user1622959
    A short time after accessing the internet, the browser/download times out. Before the timeout, the internet works OK briefly; afterwards, the wireless is still connected with a strong signal, but every internet access results in a timeout. When I leave the PC for a while, the internet is back just to timeout again as soon as I start using it. The same happens when I reconnect to the router. Also, when I surf the internet, it takes a couple of minutes until the timeout, but when I download something, it times out in a matter of seconds. The wireless adapter works just fine in Windows and internet via ethernet cable works just fine in Ubuntu. Does anyone have the same problem or knows a solution. I use Ubuntu 12.10 x64. The problem occurs since I installed ubuntu (which was a few days ago). Here some stuff that might be usefull: serus@serus-Ubuntu-PC:~$ lsusb Bus 002 Device 002: ID 0cf3:1002 Atheros Communications, Inc.

  • Weird system freeze. Nothing works keyboard/mouse/reset button - Ubuntu 12.04 64bits [closed]

    - by Simon
    I have fresh PC: i5 3570K with Intel 4000 onboard ASrock Z77 Extreme4-m 8GG RAM - Adata 1333Mhz... 1TB Seagate drive 7200rpm I've also fresh systems - Ubuntu/Win7 and today there was something strange. Ubuntu twice just freezed. Everything stopped, even keyboard and mouse wasn't responding. Even RESET button didn't work. Right now memtest is running, but I'd like to know, where else can i look for cause. Can it be software fault if even reset isn't working? Only long reset pressing rebooted PC... I'm a bit confused. Or should I test components - CPU, motherboard, disk. Which logs in Ubuntu should I check to diagnose cause? EHm I had few adventures with this PC already. Shipped motherboard was broken (ASrock Z68 Extreme3) and had old bios, so I had to contact with reseller, replace it and at the end decided on Z77, but everything took 3 weeks, so I have bad feelings... Edit: Both freezes were during editing something in gedit (it can be coincidence) and after few updates today - when memtest is end I'll check what was updated

  • Warning in Apache log: Cannot get media type from 'x-mapp-php5'

    - by IronGoofy
    I have no idea what is causing this issue, but it seems to be related to the displayed file (just a simple index.php to print phpinfo) being in an aliased directory. Any suggestions what I can do to avoid the warning? Here's an excerpt from my httpd.conf: <Directory "<dir with broken php>"> Options Indexes FollowSymLinks ExecCGI Includes AllowOverride All Order allow,deny Allow from all </Directory> Alias /smartersoftware/ "<broken dir>" <FilesMatch \.php$> SetHandler application/x-httpd-php </FilesMatch> The last three lines were required to make php work at all (which I found a bit strange, and it may or may not be related to my problem). Adding a AddType application/x-mapp-php5 .php didn't change anything.

  • How important is Domain knowledge vs. Technical knowledge?

    - by Mayank
    I am working on a Trading and Risk Management application and although from a C# background, I have been asked to work on SSIS packages. Now I can live with that. The pain point is that there is too much emphasis on business understanding. Trading (Energy Trading to be exact) is a HUGE area and understanding every little bit of it is overwhelming. But for the past two months I have been working on understanding the business terms - Mark To Market, Risk Metrics, Positions, PnL, Greeks, Instruments, Book Structure... every little detail (you get the point). Now IMHO, this is the job of a BA. Sure it is very important for developers to understand the business but where do you draw the line? When I talked to my manager about this, he almost mocked me by saying that anybody can learn a technology in a week. It's the business that's harder. My long term aspiration is to remain on the technical side, probably become an architect (if possible). If I wanted to focus so much on business I would have pursued an MBA! I want to know if I am wrong or too naive in understanding the business importance or is my frustration justified?

  • Secure copy in Linux

    - by Michael
    Hi all, I wanna simpy exchange 3 directories to a collegue's home directory (I dont have write access to that one) from my home directory, probably using secure copy if possible. I am not good with Linux command line, so I am not sure how to do that and I would very much appreciate it if somebody could help me a bit out with this. I guess it should look something like that scp -r /home/user1/directoy1 /home/user2/directoy1 scp -r /home/user1/directoy2 /home/user2/directoy2 scp -r /home/user1/directoy3 /home/user2/directoy3 Do I need to specify the login name of my collegue so that the files can be copied when he enters his password? Thanks for your help, Michael

  • how to get the update manager window visible?

    - by Max Waterman
    I can see from the launcher that the Update Manager is running - it has the little triangle by it. However, I am having trouble seeing the window. If I click on it from one desktop, it switches to another, so I assume that the Update Manager has its window on that other desktop, but it still doesn't show anything. If I click alt-tab to switch between apps, I can see that the Update Manager is there, but selecting it just shows me a blank screen. Also, when I select it, while still holding the alt-key, I see the top menu bar switch to 'Update Manager', but when I release alt, it changes back to Ubuntu Desktop. It's almost like the app is off the screen somewhere, perhaps with just a single pixel showing or something like that. disclaimer: One thing that might be affecting things is that I have 'focus follows mouse' configured, which makes things a bit funky with the menu not being on the window, where it should be (perhaps there's a way to put it back with the window?) - I like to be able to type into background windows, and manually control which window is in the foreground.

  • VLC 2.0: can't enable UPnP support

    - by Craig
    I'm attempting to use VLC 2.0.1 (Intel 64 bit) to connect to a UPnP server (Serviio 0.6.2 on OS X Snow Leopard). I've tried to enable the feature by right clicking the "Universal Plug 'n Play" node in the LOCAL NETWORK section of the Main Window. While I am able to select 'Enable', the setting doesn't seem to 'stick'. Moreover, UPnP isn't listed in the Playlist Service discovery section of the preferences. The 'Service discovery modules' is currently set to upnp_intel:sap. I am able to connect to the UPnP server with my Samsung TV, so I know that the service works.

  • OpenVPN Permission Denied Error

    - by LordCover
    I am setting OpenVPN up, and I'm in the state of adding users. Details: Host System: Windows Server 2003 32-bit. Guest System: Ubuntu Linux (with OpenVPN installed already), actually I downloaded it from OpenVPN.Net. Virtualization: VMWare v7.0 Problem: I can access the Access Server web portal (on the port 5480), but when I login to http://host_ip:943/admin and enter my (correct) login info, it shows me a page saying that "You don't have enough permissions". I am the (root) user!!!! that is really weird!!! Note: if I enter wrong login it will denote an incorrect login, this means that I am logging in successfully but the problem comes after the login process. What I tried: I tried to create another user after (root) logging in to Linux Bash using (useradd) command, but the same resulted.

  • Two graphical entities, smooth blending between them (e.g. asphalt and grass)

    - by Gabriel Conrad
    Supposedly in a scenario there are, among other things, a tarmac strip and a meadow. The tarmac has an asphalt texture and its model is a triangle strip long that might bifurcate at some point into other tinier strips, and suppose that the meadow is covered with grass. What can be done to make the two graphical entities seem less cut out from a photo and just pasted one on top of the other at the edges? To better understand the problem, picture a strip of asphalt and a plane covered with grass. The grass texture should also "enter" the tarmac strip a little bit at the edges (i.e. feathering effect). My ideas involve two approaches: put two textures on the tarmac entity, but that involves a serious restriction in how the strip is modeled and its texture coordinates are mapped or try and apply a post-processing filter that mimics a bloom effect where "grass" is used instead of light. This could be a terrible failure to achieve correct results. So, is there a better or at least a more obvious way that's widely used in the game dev industry?

  • Using Ogre with android [closed]

    - by Rich
    I am trying get Ogre 3d to work on android, I have managed to download and run the ogre sample browser but I am really struggling with trying to get a basic application working i have been trying for days now with no avail. Does anyone have any pointers on where to start with this? Thanks if anyone can help EDIT: Very sorry for my rubbish question! I am a bit new to this and I am just trying to seek some guidance. Ok so i followed the instructions on the Ogre wiki to build ogre for android and the sample browser here: http://www.ogre3d.org/tikiwiki/tiki-index.php?page=CMake+Quick+Start+Guide&tikiversion=Android so it is deffinately possible. The issue I am having is knowing what I need to do to get started with ogre e.g just a simple hello world style app where it might just show the ogre head, so tutorials might actually be good because I could not really find any simple ones as I am very new to 3D development. I just found that the sample browser was just massive and yes it has everything in it but it's very difficult to understand how it all works. What I am asking is basically some help, as I have been trying to pull out some parts of the sample browser to just create a view with a 3D model. Hope this is better?

  • Looking for way to download all the free software I need to setup my PC all at once . . .

    - by Jim McKeeth
    I am in the middle of reinstalling Windows 7, and I would like to install all the software in as few steps as possible. I saw a web site recently that listed a lot of different Freeware and Opensource appliations. There was a checkmark next to each one so you could select the ones you want, and then they would all download in a single package to install at one time. The idea was for when you were setting up after a fresh install. It was for Windows and they were adding 64-bit applications.

  • Server reboots every 4.5-5.5 minutes...

    - by Andy
    Hi, I've recently installed a server in colocation, and my server is rebooting every 4.5-5.5 minutes. Regardless of the OS I run, it reboots. I have all ECC memory in the server, so it should correct errors if there is a bad bit in the memory, right? It's weird because it always happens about 4.5-5.5 minutes after bootup. My motherboard is a Supermicro X8DTL-iF. I read on a blog that another person had the problem, and supermicro recommended to do a BIOS update. Is this the right course of action?

  • Control convention for circular movement?

    - by Christian
    I'm currently doing a kind of training project in Unity (still a beginner). It's supposed to be somewhat like Breakout, but instead of just going left and right I want the paddle to circle around the center point. This is all fine and dandy, but the problem I have is: how do you control this with a keyboard or gamepad? For touch and mouse control I could work around the problem by letting the paddle follow the cursor/finger, but with the other control methods I'm a bit stumped. With a keyboard for example, I could either make it so that the Left arrow always moves the paddle clockwise (it starts at the bottom of the circle), or I could link it to the actual direction - meaning that if the paddle is at the bottom, it goes left and up along the circle or, if it's in the upper hemisphere, it moves left and down, both times toward the outer left point of the circle. Both feel kind of weird. With the first one, it can be counter intuitive to press Left to move the paddle right when it's in the upper area, while in the second method you'd need to constantly switch buttons to keep moving. So, long story short: is there any kind of existing standard, convention or accepted example for this type of movement and the corresponding controls? I didn't really know what to google for (control conventions for circular movement was one of the searches I tried, but it didn't give me much), and I also didn't really find anything about this on here. If there is a Question that I simply didn't see, please excuse the duplicate.

  • Displaying a Grid of Data in ASP.NET MVC

    One of the most common tasks we face as a web developers is displaying data in a grid. In its simplest incarnation, a grid merely displays information about a set of records - the orders placed by a particular customer, perhaps; however, most grids offer features like sorting, paging, and filtering to present the data in a more useful and readable manner. In ASP.NET WebForms the GridView control offers a quick and easy way to display a set of records in a grid, and offers features like sorting, paging, editing, and deleting with just a little extra work. On page load, the GridView automatically renders as an HTML <table> element, freeing you from having to write any markup and letting you focus instead on retrieving and binding the data to display to the GridView. In an ASP.NET MVC application, however, developers are on the hook for generating the markup rendered by each view. This task can be a bit daunting for developers new to ASP.NET MVC, especially those who have a background in WebForms. This is the first in a series of articles that explore how to display grids in an ASP.NET MVC application. This installment starts with a walk through of creating the ASP.NET MVC application and data access code used throughout this series. Next, it shows how to display a set of records in a simple grid. Future installments examine how to create richer grids that include sorting, paging, filtering, and client-side enhancements. We'll also look at pre-built grid solutions, like the Grid component in the MvcContrib project and JavaScript-based grids like jqGrid. But first things first - let's create an ASP.NET MVC application and see how to display database records in a web page. Read on to learn more! Read More >

  • Raspberry Pi, Time Capsule Progress

    - by Richard Jones
    So by way of an update. I thought all was good with my Raspberry Pi, Debian and Netatalk Apple Time Capsule Clone. However something very strange going on. Although I could backup my Mac's + PC's fine to Raspberry Pi with external USB HD; strangely with RPI running, I couldn't use AirPlay. I found myself unable to play anything from Mac to Apple TV. So after lots of trying to make this work, I about turned and finally went out and got myself a 2TB Apple Time Capsule. More cash than I would want to spend on anything like this, but Apple you got me. I would like to offer a top tip, which maybe goes a small way to justifying silly expenditure... You can easily add a USB HD to any Time Capsule. I've just added a 3 TB external USB HD, giving me a 5 TB of total backup grunt. 3 TB External USB HD, was peanuts by comparison to Apple kit. So all working, its all solid as you'd expect.Apple 2, maybe me .5. But strong, solid backups now happening, without hassle (but a bit of a credit card bill to follow)

  • Hello PCI Council, are you listening?

    - by David Dorf
    Mention "PCI" to any retailer and you'll instantly see them take a deep breath and start looking for the nearest exit.  Nobody wants to be insecure, but few actually believe that PCI does anything more than focus blame directly on retailers.  I applaud PCI for making retailers more aware of the importance of security, but did you have to make them PAINFULLY aware?  POS vendors aren't immune to this pain either as we have to undergo lengthy third-party audits in addition to the internal secure programming programs.  There's got to be a better way. There's a timely article over at StorefrontBacktalk that discusses the inequity of PCI's rules, and also mentions that the PCI Council is accepting comments until April 15th. As a vendor, my biggest issue with PCI is that they require vendors to disclose the details of any breaches, in effect "ratting out" customers.  I don't think its a vendor's place to do this.  I'd rather have the trust of my customers so we can jointly solve the problem. Mary Ann Davidson, Oracle's Chief Security Officer, has an interesting blog posting on this very topic.  Its a bit of a long read, but I found it very entertaining and thought-provoking.  Here's an excerpt: ...heading up the list of “you must be joking” regulations are recent disturbing developments in the Payment Card Industry (PCI) world. I’d like to give [the] PCI kahunas the benefit of the doubt about their intentions, except that efforts by Oracle among others to make them aware of “unfortunate side effects of your requirements” – which is as tactful I can be for reasons that I believe will become obvious below - have gone, to-date, unanswered and more importantly, unchanged. I encourage you to read the entire posting, Pain Comes Instantly, and then provide feedback to the PCI Council.

  • My internet connection slows or dies unexpectedly

  • How to use graphical line drawing characters with Midnight Commander on OS X under ssh?

    - by Sorin Sbarnea
    I discovered that when I do ssh to a machine using OS X 10.6 and use mc I do not see the graphical line drawing characters. This does not happen if I open terminal and start mc. I'm connecting using putty configured to use xterm-color, configuraton that works just fine if I do ssh to a linux machine. The mc from OS X is version 4.7.0 (installed using macports). What locale returns: LC_CTYPE="C" <== ssh LC_CTYPE="UTF-8" <== Terminal.app ssh: mc display bits shows: 7-bit ASCII (changing does not help, it defaults to the same value) Terminal.app: mc display bits shows: UTF-8 The environment shows TERM=xterm-color in both cases Terminal.app and ss but mc looks different. I filed a bug to mc with this information at http://www.midnight-commander.org/ticket/2339

  • Ubuntu crashes with menu bar launcher freeze during software centre use

    - by UbunUser
    I recently reinstalled Ubuntu 12.04 LTS on a Dell Studio 1588 64-bit and ran into crashes as I was installing some software on the software centre. Before this, I had display/screen problems that I needed to fix so I will briefly describe that in case it has any connection to the crashes. The problem was of screen crash/flickering (related to ATI Mobility Radeon HD 5400x) when trying to adjust brightness and so I followed guidance from an earlier chain (question 131967) to (a) use jockey to install fglrx update driver (deactivate experimental beta driver) and (b) edit grub to add acpi_backlight=vendor dell_laptop.backlight=0 The crashes that happened (twice, while software centre was just finishing installation in the background) was that all tabs (on open Firefox window) stayed open along with cursor control with mousepad but all menu bars disappeared completely along with the launcher and the keyboard also turned unresponsive. So there seemed to be no way to close windows or shut down the computer except for a forced hard shut down of the system using the start button. This is very similar to Questions #167540 and #298843, which seem to be closed. Why is this happening? Is there some update or fix I need to make? Thanks!
