• from Java to SAS

  - by Giovanni Rossi

  I am a seasoned python,java,...other programmer having a (fairly advanced) mathematical education (so I do understand statistics and data mining, for example) . For various reasons I am thinking to switch to SAS/BI area (I am naming SAS because it might be, for me, a possible way to enter in BI). My question, for whoever might have an experience of both: is it, in BI current state, worth it? I mean, the days of big ideas in BI for business seem to be over (there are the APIs, managers think that they know what you can do with them), and my mathematical background might turn out to be superflous. Also, the big companies now have their data organized, have their BI procedures well established, and trying to analyze it from a different standpoint might not be what they want. Another difference is: while in Java etc. development one codes and codes and codes, I don't know if this is the case for BI; in fact, from what I read on the net, a BI (or OLAP, ...etc) developer, in a big organization, is usually in a state of standby, and does in fact little coding. Any opinions, and in particular strong opinions, will be appreciated.

• "custom" routers for VPN - useful or waste of money?

  - by Andrew Heath

  I use VPN in China and my current service contract expires soon so I was checking what sort of plans are out there now. I found that Witopia offers a "Cloak Box", what appears to be a Linksys wireless router with allegedly hacked/custom firmware to support VPN. Aside from allowing multiple computers to share one VPN connection, is there anything else at work here to justify that price when most new routers are $100 or less these days? Or is this something targeted towards the cd-rom cupholder crowd? And yes, I've contacted them, but haven't heard back yet... EDIT I've heard back from the company - here are the details if anyone else is interested: the router is a Linksys WRT54GL running TomatoVPN custom firmware the hardware waranty is one (1) year, from Linksys/Cisco the VPN is hard-set, so any device connected to the router MUST use the VPN (Witopia blocks torrents) I've decided it's not for me, but hopefully this information will prove useful to others.

• Move model forward base on model orientation

  - by ChocoMan

  My model rotates on it's own Y-axis regardless of where it is in the world. Here are the controls for the left ThumbStick: UP (move model forward on Z-Axis) DOWN (move model backward on Z-Axis) LEFT & RIGHT (strafe to either side) The problem is adjusting the direction the model's orientation UP and DOWN if the player should also rotate the player while moving forward or backwards. An example what Im trying to achieve would be a car doing donuts. The car is always facing the current direction that it interprets as forward (or rear as backwards) in relation to it's local rotation. Here is how Im calling the movement: // Rotate model with Right Thumbstick along X-Axis modelRotation -= pController.ThumbSticks.Right.X * mRotSpeed; // Move Forward if (pController.IsButtonDown(Buttons.LeftThumbstickUp)) { modelPosition.Z -= -pController.ThumbSticks.Left.Y * speed; } // Move Backward if (pController.IsButtonDown(Buttons.LeftThumbstickDown)) { modelPosition.Z += pController.ThumbSticks.Left.Y * speed; } // Strafe Left if (pController.IsButtonDown(Buttons.LeftThumbstickLeft)) { modelPosition.X += -pController.ThumbSticks.Left.X * speed; } // Strafe Right if (pController.IsButtonDown(Buttons.LeftThumbstickRight)) { modelPosition.X -= pController.ThumbSticks.Left.X * speed; } // DeadZone if (!pController.IsButtonDown(Buttons.LeftThumbstickUp) && !pController.IsButtonDown(Buttons.LeftThumbstickDown) && !pController.IsButtonDown(Buttons.LeftThumbstickLeft) && !pController.IsButtonDown(Buttons.LeftThumbstickRight)) { }

• Making an interactive 2D map

  - by Chad

  So recently I have been working on a Legend of Zelda: A Link to the Past clone, and I am wondering how I could handle certain map interactions (like cutting grass, lifting rocks, etc). The way I am currently doing the tilemap is with 2 PNGs. The first is the "tilemap" where each pixel represents a 16x16 tile and the (red, green) values are the (x, y) coords for the tile in the second PNG (the "tileset"). I am then using the blue channel to store collision data. Each tile is split into 4 8x8 tiles and represented by a 2 bit value (0 = empty, 1 = Jumpdown point, 2 = unused right now, 3 = blocking). 4 of these 2 bit values make up the full blue channel (1 byte). So collisions work great, and I am moving on to putting interactive units on the level; but I am not sure what a good way is to do it. I have experimented with spawning an entity for each grass and rock, but there are just WAY to many; FPS just dies even if I confine it to the current "zone" the user is in (for those who remember LTTP it had zones you moved between). It does make a difference that this is a browser-based JavaScript game. tl;dr: What is a good way to have an interactive map without using full blown entities for each interactive item?

• SAP or Navision? Career Path

  - by codebased

  This could be tricky to ask; I may or may not ask this question here but I thought to give it a try. I've been in Software Industry since 2002 and now it has been a time that I'm at Senior level where I normally code, lead and define the architect; giving technical solutions to the management is one of my asset that I've earned during my services. Now it is the time to define the road map for the future, $$$. I am not in favor of Project Management roles. I've been thinking of going through the ERP and my current company does provide me an option to go for Navision/ Microsoft Dynamics. They are currently on 4.0 but they are planning to move for 2009 and also to build one of their own plug-in. Indeed the option is good because Microsoft is trying to accomplish the market for Dynamics products. However, they have less success in Australia. Now, Another option is with SAP where person can go with 200 K $ a year. Where as I'd doubt that if the same kind of growth, financial, is available for Microsoft geek. What is your opinion on Navision or SAP? If I try to completely move to SAP it could be bit challenging as market will consider me a fresher. However the return is quite good. Where in case of Microsoft, I think technology changes so fast that there is a less chance to grow in, within, the same experience; in other word, if any new framework comes in .net then market look for that person who knows this new framework and not .net But in case of SAP, where the base remain same and chances are to grab more money from the market. What would you do if you were me? In stackoverflow - Navision questions are 20+ where in SAP 200+///?? :-)

• How can I use iteration to lead targets?

  - by e100

  In my 2D game, I have stationary AI turrets firing constant speed bullets at moving targets. So far I have used a quadratic solver technique to calculate where the turret should aim in advance of the target, which works well (see Algorithm to shoot at a target in a 3d game, Predicting enemy position in order to have an object lead its target). But it occurs to me that an iterative technique might be more realistic (e.g. it should fire even when there is no exact solution), efficient and tunable - for example one could change the number of iterations to improve accuracy. I thought I could calculate the current range and thus an initial (inaccurate) bullet flight time to target, then work out where the target would actually be by that time, then recalculate a more accurate range, then recalculate flight time, etc etc. I think I am missing something obvious to do with the time term, but my aimpoint calculation does not currently converge after the significant initial correction in the first iteration: import math def aimpoint(iters, target_x, target_y, target_vel_x, target_vel_y, bullet_speed): aimpoint_x = target_x aimpoint_y = target_y range = math.sqrt(aimpoint_x**2 + aimpoint_y**2) time_to_target = range / bullet_speed time_delta = time_to_target n = 0 while n <= iters: print "iteration:", n, "target:", "(", aimpoint_x, aimpoint_y, ")", "time_delta:", time_delta aimpoint_x += target_vel_x * time_delta aimpoint_y += target_vel_y * time_delta range = math.sqrt(aimpoint_x**2 + aimpoint_y**2) new_time_to_target = range / bullet_speed time_delta = new_time_to_target - time_to_target n += 1 aimpoint(iters=5, target_x=0, target_y=100, target_vel_x=1, target_vel_y=0, bullet_speed=100)

• "Automatically Connect" option for Mobile Broadband crashes GNOME Shell, how to remove network configurations?

  - by Kush

  I'm using Fedora 15, in GNOME Shell, my mobile broadband connection was working absolutely fine, until I set the connection type to Connect Automatically using nm-connection-manager. Now, when I start the Fedora, the Top panel network icon shows red exclamation symbol and when I click it, instead of showing me available networks' list, it shows only "Network Settings", and when I open it, it shows GNOME 3's new Network Manager app, and it pops out the dialog saying that, "Current network settings service is incompatible with this version". And after a few seconds of log in, the shell freezes and all I can do is log out using Ctrl+Alt+BackSpace. I'm facing this problem since I opened old network manager app using nm-connection-manager in the run dialog, and editing my connection to connect automatically. After logging in to the shell I somehow managed to delete that connection from the same app and created a new one, but the problem still exists. How can I delete all network preferences (by deleting its configuration files from my home directory or something like that) and reset the GNOME 3's network manager to its default state?

• benchmark tcp: ab or iperf like tool to send hex/binary/pcap data?

  - by olan

  Hello all, I have written a server in Twisted for a current project I'm working on, and now I need to test it. It receives TCP packets, with the payload consisting of just a serialised binary string. I want to be able to test the server for concurrency/throughput using the binary data as the payload, but can not find any tool that will allow me to do this. I tried iperf -F but it didn't work, as I think it was sending the binary/hex data as chars. I've also looked at ab which seems to be perfect - if only for http. As well as these, I've had a look at tcpreplay, but it doesn't perform any testing (or establish TCP connections) so it's not much use. Any help would be greatly appreciated as I'm rather stuck on this one!

• Code maintenance: keeping a bad pattern when extending new code for being consistent or not ?

  - by Guillaume

  I have to extend an existing module of a project. I don't like the way it has been done (lots of anti-pattern involved, like copy/pasted code). I don't want to perform a complete refactor. Should I: create new methods using existing convention, even if I feel it wrong, to avoid confusion for the next maintainer and being consistent with the code base? or try to use what I feel better even if it is introducing another pattern in the code ? Precison edited after first answers: The existing code is not a mess. It is easy to follow and understand. BUT it is introducing lots of boilerplate code that can be avoided with good design (resulting code might become harder to follow then). In my current case it's a good old JDBC (spring template inboard) DAO module, but I have already encounter this dilemma and I'm seeking for other dev feedback. I don't want to refactor because I don't have time. And even with time it will be hard to justify that a whole perfectly working module needs refactoring. Refactoring cost will be heavier than its benefits. Remember: code is not messy or over-complex. I can not extract few methods there and introduce an abstract class here. It is more a flaw in the design (result of extreme 'Keep It Stupid Simple' I think) So the question can also be asked like that: You, as developer, do you prefer to maintain easy stupid boring code OR to have some helpers that will do the stupid boring code at your place ? Downside of the last possibility being that you'll have to learn some stuff and maybe you will have to maintain the easy stupid boring code too until a full refactoring is done)

• What platform to use for browser based turn based strategy game

  - by sunwukung

  I want to write a browser based strategy game that can be played by two players in separate locations. The game itself is predominantly turn based. To that end, I want to determine the correct platform on which to build this game. To prevent gamers "gaming" the system, the business logic needs to reside in the server. I could arguably use AJAX for a large part of the games functionality, but at two key points in the game loop, the opposing player can "counter" the current players move. In addition, when it's time for the players to swap, AJAX polling is likely to fall short, so it's starting to look like WebSockets is going to be a requirement to pull this off smoothly. So, the remaining question is regarding the back end. I'd kinda like to build this in Python/Flask - but this is primarily out of wanting to tackle a project with that language, not neccessarily because it's the appropriate tool for the job. The next most likely candidate has got to be NodeJS given it's (apparently) tighter integration with the WebSockets protocol. My question, then, is regarding the best platform on which to pursue this objective.

• Code Contracts and Pex at MSDN Live 2010

  - by terje

  One of the 6 sessions I and Mikael Nitell is running on MSDN Live 2010 here in Norway is about Code Quality, and part of that session goes through the use of Code Contracts and Pex.  Both fantastic tools ! They can be used togethers, but are also completely independent from each other, and can be used as a single Code Contracts  has to downloaded separately from VS 2010 (works also on VS 2008).   Start looking at http://msdn.microsoft.com/en-us/devlabs/dd491992.aspx . This download is a free download.   Code Contracts originates form the ideas of Bertrand Meyer – Design by Contract, take a look here. Pex is found on the MSDN Subscription download, so it requires an active MSDN Subscription. Start to get it from here http://research.microsoft.com/en-us/projects/pex/downloads.aspx .  The current version as of 14.4.10 is 0.9, which works with the 2010 RC.  A new version is due this week.  Pex is a tool to generate unit tests, and does this very intelligently.  Perfect to make tests for legacy code, but also to make sure you get all paths tested.  See the Reference information and project startup information.

• FreeType2 Crash on FT_Init_FreeType

  - by JoeyDewd

  I'm currently trying to learn how to use the FreeType2 library for drawing fonts with OpenGL. However, when I start the program it immediately crashes with the following error: "(Can't correctly start the application (0xc000007b))" Commenting the FT_Init_FreeType removes the error and my game starts just fine. I'm wondering if it's my code or has something to do with loading the dll file. My code: #include "SpaceGame.h" #include <ft2build.h> #include FT_FREETYPE_H //Freetype test FT_Library library; Game::Game(int Width, int Height) { //Freetype FT_Error error = FT_Init_FreeType(&library); if(error) { cout << "Error occured during FT initialisation" << endl; } And my current use of the FreeType2 files. Inside my bin folder (where debug .exe is located) is: freetype6.dll, libfreetype.dll.a, libfreetype-6.dll. In Code::Blocks, I've linked to the lib and include folder of the FreeType 2.3.5.1 version. And included a compiler flag: -lfreetype My program starts perfectly fine if I comment out the FT_Init function which means the includes, and library files should be fine. I can't find a solution to my problem and google isn't helping me so any help would be greatly appreciated.

• Replacing a W2K3 Domain Controller - what do I need to know?

  - by Marko Carter

  I have a network of around 70 machines, currently with two DCs both running Windows Server 2003 (DC0 & DC1). DC0 is a five year old Poweredge 1850 and has recently become increasingly flakey, and in the past fortnight has fallen over twice. I want to replace this machine, but I'm cautious as there is huge scope for this sort of thing to go wrong. The way I imagine doing this is building a new machine then doing a DCPROMO and running three domain controllers for a month or so until I'm happy that everything is working as it should be before retiring the old machine. Particular areas of concern are the replication of roles from the current controllers (GP settings for instance) and the ramifications of switching off the machine that has, up until now, been the 'primary'. If there are compelling reasons to use Server 2008 I'm willing to do so, however I don't know if this would cause problems with my exisiting 2003 machines. Any advice on best practice or previous experiences would be most welcome.

• Modify .htm files on wireless router

  - by mdeitrick

  What am I trying to do? I am attempting to access the .htm files on my wireless router to modify the look and feel of the Netgear GENIE webpage(s). What have I done? I've read several articles on eHow and Instructables that detail how to setup your router as an FTP server, since I figured the best way to access the files would be through FileZilla. Setting up an FTP server through my router doesn't sound like what I should do to accomplish my task... or perhaps it is? I've also read the documents provided by Netgear for getting started and setting up functionality on the router. Maybe I overlooked something? My specifications Netgear router WNR2000v3 FileZilla v3.8.1 UPDATE: Since someone voted to close this question I'll clarify what I'm asking for... At the present I am dissatisfied with the current UI/webpage look when logging into routerlogin.net. Furthermore I would like to make changes to the admin dashboard.

• Windows command line built-in compression/decompression tool?

  - by Will Marcouiller

  I need to write a batch file to unzip files to their current folder from a given root folder. Folder 0 |----- Folder 1 | |----- File1.zip | |----- File2.zip | |----- File3.zip | |----- Folder 2 | |----- File4.zip | |----- Folder 3 |----- File5.zip |----- FileN.zip So, I wish that my batch file is launched like so: ocd.bat /d="Folder 0" Then, make it iterate from within the batch file through all of the subfolders to unzip the files exactly where the .zip files are located. So here's my question: Does the Windows (from XP at least) have a command line for its embedded zip tool? Otherwise, shall I stick to another third-party util?

• What techniques would you use for a next generation java web application?

  - by jakob

  I'm working at a site similar to Foursquare and Yelp, with approximately 100000 unique requests each week that generates content, growing steadily. We are currently using: Seam as Java web framework. MySQL as DB Hibernate as ORM Hibernate Search as Index EhCache for Caching. Since our site is slowly growing out of the current setup and has a lot of legacy code, it is time for us to start thinking about a major refactoring/changing setup. Web framework We are not ready to change the language but we are leaning towards Spring Web Framework, since: Seam is no more. Almost all of us have worked with Spring and liked it. DB and ORM We have done a little research and we are thinking about MongoDB. Index Do we need to have a separate Index if we use MongoDB? Cache ? So my question is basically: If you take Spring Web Framework and MongoDB into consideration, how would a good setup be for a web application that is growing and handles a lot of logged in users generating input and performing searches?

• Client side latency when using prediction

  - by Tips48

  I've implemented Client-Side prediction into my game, where when input is received by the client, it first sends it to the server and then acts upon it just as the server will, to reduce the appearance of lag. The problem is, the server is authoritative, so when the server sends back the position of the Entity to the client, it undo's the effect of the interpolation and creates a rubber-banding effect. For example: Client sends input to server - Client reacts on input - Server receives and reacts on input - Server sends back response - Client reaction is undone due to latency between server and client To solve this, I've decided to store the game state and input every tick in the client, and then when I receive a packet from the server, get the game state from when the packet was sent and simulate the game up to the current point. My questions: Won't this cause lag? If I'm receiving 20/30 EntityPositionPackets a second, that means I have to run 20-30 simulations of the game state. How do I sync the client and server tick? Currently, I'm sending the milli-second the packet was sent by the server, but I think it's adding too much complexity instead of just sending the tick. The problem with converting it to sending the tick is that I have no guarantee that the client and server are ticking at the same rate, for example if the client is an old-end PC.

• I want to install an MSI twice

  - by don.vince

  I have a peculiar wish to install an msi twice on a machine. The purpose of the double install is to first install under the pre-production folder, run the deployment in a safe environment prior to deploying in the production folder. We typically use separate machines to represent these different environments however in this case I need to use the same box. The two scenarios I get are as follows: I've installed pre-production, I'm happy, I want to install production, I run the msi, it asks whether I want to repair or remove the installation I've production installed, I want to install the new version of the msi, it tells me I already have a version of the product installed and I must first un-install the current version The first scenario isn't too bad as we can at that point sensibly un-install and re-install under the production folder, but the second scenario is a pain as we don't want to un-install the live production deployment. Is there a setting I can give to msiexec that will allow this? Is there a more suitable different approach I could use?

• How to protect your real time online shooter from potential bots

  - by Zaky German

  I'm looking to create a multiplayer top down shooter. While i've read about different topics, i can see them i've got some real challenges ahead, but i'm all up for it. One thing i can't understand is how am i supposed to be protecting the game from people who try to create bots? What i mean is, as far as i understand, it's impossible to protect the network traffic in a way that players won't be able to create programs that listen to what's going on and understand it. So what worries me is that people can create bots that listen to the current location of rival players, and send communication that mimic as if the player is shooting in the exact "perfect" location to win that match. So what kind of techniques are used to protect real time games from such bots? Also i'd like to mention that i've tried searching for discussions (as this sounds like something many people struggle with), but couldn't find anything about it specifically, only as a part of broader questions about networking in real time games. If i should have looked harder feel free to put me in my place :) Thanks alot!

• Use Network-Manager to Connect to a wifi Access Point on the command-line

  - by Stefano Palazzo

  I'd like to connect to a wireless access point from the command-line. ideally, I'd only need the name of the AP. But the hardware-address would work as well. I know I can use nmcli to connect to a managed network connection, but in my case, the access point may not be configured for Network-Manager yet (See the difference between the output of nm-tool and nmcli con). Example output of nmcli: Auto pwln 3a3d62b1-bbdf-4f76-b4d2-c211fd5cfb03 802-11-wireless [...] Wired Network aa586921-accf-4932-98c4-c873c310f08e 802-3-ethernet [...] Cisco-UDP Uni 7f94847b-04dc-40b7-9955-5246fb77cc65 vpn [...] T-mobile (D1) 867f345a-cbbf-4bd4-b883-a5e5ae0932f0 gsm [...] Example output of nm-tool: State: connected - Device: eth1 [Auto pwln] ---------------------------------------------------- [...] Wireless Access Points (* = current AP) *pwln: Infra, [...], Freq 2472 MHz, Rate 54 Mb/s, Strength 80 WPA WPA2 WLAN: Infra, [...], Freq 2422 MHz, Rate 54 Mb/s, Strength 20 WPA WPA2 [...] How do I connect to an access point that may or may not be known to NM? Extra: Finding out if the connection needs a pass-phrase, and submitting it on the command-line as well would be great too (that is to say It'd be nice if network-manager wouldn't pop open any keyring dialogues or errors on the gui)

• Standards for how developers work on their own workstations

  - by Jon Hopkins

  We've just come across one of those situations which occasionally comes up when a developer goes off sick for a few days mid-project. There were a few questions about whether he'd committed the latest version of his code or whether there was something more recent on his local machine we should be looking at, and we had a delivery to a customer pending so we couldn't wait for him to return. One of the other developers logged on as him to see and found a mess of workspaces, many seemingly of the same projects, with timestamps that made it unclear which one was "current" (he was prototyping some bits on versions of the project other than his "core" one). Obviously this is a pain in the neck, however the alternative (which would seem to be strict standards for how each developer works on their own machine to ensure that any other developer can pick things up with a minimum of effort) is likely to break many developers personal work flows and lead to inefficiency on an individual level. I'm not talking about standards for checked-in code, or even general development standards, I'm talking about how a developer works locally, a domain generally considered (in my experience) to be almost entirely under the developers own control. So how do you handle situations like this? Are the one of those things that just happens and you have to deal with, the price you pay for developers being allowed to work in the way that best suits them? Or do you ask developers to adhere to standards in this area - use of specific directories, naming standards, notes on a wiki or whatever? And if so what do your standards cover, how strict are they, how do you police them and so on? Or is there another solution I'm missing? [Assume for the sake of argument that the developer can not be contacted to talk through what he was doing here - even if he could knowing and describing which workspace is which from memory isn't going to be simple and flawless and sometimes people genuinely can't be contacted and I'd like a solution which covers all eventualities.]

• new project; entire node.js app

  - by Jared

  I have been looking into Node.js, express and Nowjs and love how easy it is to have real time interactions between clients. My background is mostly from CodeIgniter MVC using PHP and MYSql. I want to re make a current web project of mine from scratch to make everything better and more real time with this newer technology. After researching and doing test examples I want to use node.js , express and Nowjs for the real time interactions once someone connects to the socket.io to pull data back to clients. But use Code Igniter for the control of the site and user management , possible shopping cart/store , pretty much everything else. This is purely due to time constraints and that I am already familiar with doing it that way. I have been looking at MongoDB as an alternative to MySql, Basically the app is going to be multiple chat rooms all on one page. with the ability of notifications and private messaging. Lots of data transfer and images. before I started piecing it together I wanted to get people who have already done something similar. My model would use Code Igniter and MySQL to render the page and then connect them onto a node.js server and broadcast using express and nowjs would using a mongoDB be better than mySQL for tons of messages and data being stored or MYSQL? Also does it make since to not make the whole site on Node.js , kinda piece it together like that? I was asked to re post this somewhere else as it was not up to the format for SO, OP from here http://stackoverflow.com/questions/12649469/new-project-need-some-start-up-advice-node-js-app#comment17062924_12649469
