  • DB API for shell scripting (any shell)

    - by foampile
    I am faced with some legacy shell scripts that run batch data processing jobs in Oracle using SQL+. For the most part, the data tier does not have to communicate back to the script with retrieved data to be passed for shell-level processing but in a few cases it does. The problem is, SQL+ is really meant to be an end user app and not an API that can communicate with other clients programmaticaly. That is why people have invented APIs such as DBD::DBI for Perl, JDBC for Java, ODBC etc. The way it is done is they invoke SQL+ and then parse the output, which is clearly designed for human eye consumption, using tools like sed and awk. The whole thing is at best a hack and very prone to bugs. Since this client is rather conservative with their technology, they don't want to scale their scripts up to Perl or Python where there are data access APIs. So I am wondering whether there are similar APIs for shell, e.g. K or bash. What I would like is if an API would return data in a 2-dimensional array or strings (for the lack of type setting) so that I can just read DB data like that. The way they do it now is akin to parsing regular web page HTML to get a single stock quote rather than cleanly calling a web service and be done with it. Anybody know of a product I can use? Thanks

  • Send an Email at a future date

    - by Ryan
    I'd like to write up an email that gets sent out in a few days. I'd prefer to use Gmail, but I could use some other client if necessary. It doesn't look like Gmail has this feature in their labs anywhere, but it could just be hiding somewhere. Any ideas? EDIT: a bit more backstory on my particular situation. My wife is out of town for three weeks, and I've decided to email her every day while she's out. Unfortunately, I myself am going camping this weekend, so I wanted to pre-record a message that gets sent while I'm out. Unfortunately, FutureMail and FutureMe both are for sending email to yourself, probably for anti-spam reasons. I guess the best solution is to use thunderbird on my laptop (so it's shielded from power outages). Seems a little excessive to keep a computer running just to send a few emails, but whatever gets the job done :).

  • Dark Sun Dispatch 001

    - by Chris Williams
    If you aren't into tabletop (aka pen & paper) RPGs, you might as well click to the next post now... Still here? Awesome. I've recently started running a new D&D 4.0 Dark Sun campaign. If you don't know anything about Dark Sun, here's a quick intro: The campaign take place on the world of Athas, formerly a lush green world that is now a desert wasteland. Forests are rare in the extreme, as is water and metal. Coins are made of ceramic and weapons are often made of hardened wood, bone or obsidian. The green age of Athas was centuries ago and the current state was brought about through the reckless use of sorcerous magic. (In this world, you can augment spells by drawing on the life force of the world & people around you. This is called defiling. Preserving magic draws upon the casters life force and does not damage the surrounding world, but it isn't as powerful.) Humans are pretty much unchanged, but the traditional fantasy races have changed quite a bit. Elves don't live in the forest, they are shifty and untrustworthy desert traders known for their ability to run long distances through the wastes. Halflings are not short, fat, pleasant little riverside people. Instead they are bloodthirsty feral cannibals that roam the few remaining forests and ride reptilians beasts akin to raptors. Gnomes are extinct, as are orcs. Dwarves are mostly farmers and gladiators, and live out in the sun instead of staying under the mountains. Goliaths are half-giants, not known for their intellect. Muls are a Dwarf & Human crossbreed that displays the best traits of both races (human height and dwarven stoutness.) Thri-Kreen are sentient mantis people that are extremely fast. Most of the same character classes are available, with a few new twists. There are no divine characters (such as Priests, Paladins, etc) because the gods are gone. Nobody alive today can remember a time when they were still around. Instead, some folks worship the elemental forces (although they don't give out spells.) The cities are all ruled by Sorcerer King tyrants (except one city: Tyr) who are hundreds of years old and still practice defiling magic whenever they please. Serving the Sorcerer Kings are the Templars, who are also defilers and psionicists. Crossing them is as bad, in many cases, as crossing the Kings themselves. Between the cities you have small towns and trading outposts, and mostly barren desert with sometimes 4-5 days on foot between towns and the nearest oasis. Being caught out in the desert without adequate supplies and protection from the elements is pretty much a death sentence for even the toughest heroes. When you add in the natural (and unnatural) predators that roam the wastes, often in packs, most people don't last long alone. In this campaign, the adventure begins in the (small) trading fortress of Altaruk, a couple weeks walking distance from the newly freed city of Tyr. A caravan carrying trade goods from Altaruk has not made it to Tyr and the local merchant house has dispatched the heroes to find out what happened and to retrieve the goods (and drivers) if possible. The unlikely heroes consist of a human shaman, a thri-kreen monk, a human wizard, a kenku assassin and a (void aspect) genasi swordmage. Gathering up supplies and a little liquid courage, they set out into the desert and manage to find the northbound tracks of the wagon. Shortly after finding the tracks, they are ambushed by a pack of silt-runners (small lizard people with very large teeth and poisoned pointy spears.) The party makes short work of the creatures, taking a few minor wounds in the process. Proceeding onward without resting, they find the remains of the wagon and manage to sneak up on a pack of Kruthiks picking through the rubble and spilled goods. Unfortunately, they failed to take advantage of the opportunity and had a hard fight ahead of them. The party defeated the kruthiks, but took heavy damage (and almost lost a couple of their own) in the process. Once the kruthiks were dispatched, they followed a set of tracks further north to a ruined tower...

  • With which class to start Test Driven Development of card game application? And what would be the next 5 to 7 tests?

    - by Maxis
    I have started to write card game applications. Some model classes: CardSuit, CardValue, Card Deck, IDeckCreator, RegularDeckCreator, DoubleDeckCreator Board Hand and some game classes: Turn, TurnHandler IPlayer, ComputerPlayer, HumanPlayer IAttackStrategy, SimpleAttachStrategy, IDefenceStrategy, SimpleDefenceStrategy GameData, Game are already written. My idea is to create engine, where two computer players could play game and then later I could add UI part. Already for some time I'm reading about Test Driven Development (TDD) and I have idea to start writing application from scratch, as currently I have tendency to write not needed code, which seems usable in future. Also code doesn't have any tests and it is hard to add them now. Seems that TDD could improve all these issue - minimum of needed code, good test coverage and also could help to come to right application design. But I have one issue - I can't decide from where to start TDD? Should I start from bottom - Card related classes or somewhere on top - Game, TurnHandler, ... ? With which class you would start? And what would be the next 5 to 7 tests? (use the card game you know the best) I would like to start TDD with your help and then continue on my own!

  • Test Data in a Distributed System

    - by Davin Tryon
    A question that has been vexing me lately has been about how to effectively test (end-to-end) features in a distributed system. Particuarly, how to effectively manage (through time) test data for feature testing. The system in question is a typical SOA setup. The composition is done in JavaScript when call to several REST APIs. Each service is built as an independent block. Each service has some kind of persistent storage (SQL Server in most cases). The main issue at the moment is how to approach test data when testing end-to-end features. Functional end-to-end testing occurs through the UI, and it is therefore necessary for test data to be set up before the test run (this could be manual or automated testing). As is typical in a distributed system, identifiers from one service are used as a link in another service. So, some level of synchronization needs to be present in the data to effectively test. What is the best way to manage and set up this data after a successful deployment to a test environment? For example, is it better to manage this test data inside each service? Or package it together with the testing suite? Does that testing suite exist as a separate project? I'm interested in design guidance about how to store and manage this test data as the application features evolve.

  • Limiting game loop to exactly 60 tics per second (Android / Java)

    - by user22241
    So I'm having terrible problems with stuttering sprites. My rendering and logic takes less than a game tic (16.6667ms) However, although my game loop runs most of the time at 60 ticks per second, it sometimes goes up to 61 - when this happens, the sprites stutter. Currently, my variables used are: //Game updates per second final int ticksPerSecond = 60; //Amount of time each update should take final int skipTicks = (1000 / ticksPerSecond); This is my current game loop @Override public void onDrawFrame(GL10 gl) { // TODO Auto-generated method stub //This method will run continuously //You should call both 'render' and 'update' methods from here //Set curTime initial value if '0' //Set/Re-set loop back to 0 to start counting again loops=0; while(System.currentTimeMillis() > nextGameTick && loops < maxFrameskip){ SceneManager.getInstance().getCurrentScene().updateLogic(); //Time correction to compensate for the missing .6667ms when using int values nextGameTick+=skipTicks; timeCorrection += (1000d/ticksPerSecond) % 1; nextGameTick+=timeCorrection; timeCorrection %=1; //Increase loops loops++; } render(); } I realise that my skipTicks is an int and therefore will come out as 16 rather that 16.6667 However, I tried changing it (and ticksPerSecond) to Longs but got the same problem). I also tried to change the timer used to Nanotime and skiptics to 1000000000/ticksPerSecond, but everything just ran at about 300 ticks per seconds. All I'm attempting to do is to limit my game loop to 60 - what is the best way to guarantee that my game updates never happen at more than 60 times a second? Please note, I do realise that very very old devices might not be able to handle 60 although I really don't expect this to happen - I've tested it on the lowest device I have and it easily achieves 60 tics. So I'm not worried about a device not being able to handle the 60 ticks per second, but rather need to limit it - any help would be appreciated.

  • Enable dtrace without sudo on Mac OS X?

    - by Juan
    How do I enable users to use dtrace on Mac OS X. I am trying to do the equivalent of strace on Linux, and I don't like running applications with elevated privileges. UPDATE Ok, the best I can tell. The only way to keep a nefarious application from ruining the system by debugging it is to. Attach to the process in a separate console Use sudo twice So that: sudo dtruss sudo -u myusername potentially_harmful_app I verified this with this short program: #include <iostream> #include <unistd.h> int main() { std::cout << "effective euid " << geteuid() << "\n"; } See this discussion for more info: http://discussions.apple.com/message.jspa?messageID=6430877

  • media player or dj software

    - by Dale
    Been searching for quite some time for a player that will cross fade correctly. What I mean by that, most players have the ability to start fading with a given time left of the song (ex:10 secs) While at times that can be fine, but is there software or a plugin for software that can tell the difference between a song that fades out, or a song that has a cold ending? So far the best one out there that I have tested is PCDJ, but I am sure there has to be something that can distinguish between endings of songs. Should add...this is for windows. Running vista Thanks in advance

  • A bounce-rate attack to manipulate SEO ?

    - by Denis Volovik
    This is a question to experienced people that might help us shed some light on the issue. We noticed a very strange behavior on our site, in Google Analytics. Some dude from Finland, namely, from Kouvola city is hitting one of our pages - only one page on our site, 'bout a hundred times per day, all with an average bounce rate of 90%+... This is causing our overall bounce rate to go up by 1 to 3% per day... which is very disturbing.. since we're trying to do our best in order to keep it as low as possible. And obviously having it jumped from ~24% to 27%, just because of that crazy dude is not making us happy at all... We tried implementing a geo-targeted script in order to catch this particular visitor and deliver him a juicy message, and it seemed like it helped in the beginning, it has stopped for a day or two, but now he's back... The geo-targeted script was also logging all IP addresses for page requests originating from Finland in order to find out more details and (in order to block them on the server level, later).. but thing is, it was all mainly cable or DSL connections with various, but not constantly repeating IPs... we are all wondering what is he up to really ? I think that this page should be kept updated with ideas on how to combat this and perhaps someone could also shed light on what it might be ? What is the reason for doing this "bounce-rate attack", as I call it? There was a similar question asked on stackoverflow earlier, with no meaningful answer - here - How to stop bounce rate manipulation.

  • How does one guarantee a remote client the same local IP address every time when connecting to a VPN?

    - by Joe Carroll
    I need to configure a VPN for secure remote access to a PACS serving DICOM radiological images. The DICOM standard requires that any clients accessing the PACS must be using a fixed IP address that is pre-registered in PACS. I haven't implemented this solution before and would appreciate any guidance. I believe it should be possible to use RADIUS on the server to authenticate users connecting to the VPN and with it assign each user their own specific local subnet IP address, which would be registered with the PACS. The server runs Windows Server 2003 R2 Enterprise Edition SP2 and the VPN device is a FortiGate 60C. The What would be the best and/or simplest way to set this up?

  • Tuning B2B Server Engine Threads in SOA Suite 11g

    - by Shub Lahiri, A-Team
    Background B2B 11g has a number of parameters that can be tweaked to tune the engine for handling high volumes of messages. These parameters are also known as B2B server properties and managed via the EM console.  This note highlights one aspect of the tuning exercise and describes the different threads, that can be configured to tune the performance of a B2B server. Symptoms The most common indicator of a B2B engine in need of a tuning is reflected in the constant build-up of messages in an internal JMS queue within the B2B server. It is called B2B_EVENT_QUEUE and can be monitored via the Weblogic server console. Whenever such a behaviour is seen, it usually results in general degradation of performance. Remedy There could be many contributing factors behind a B2B server's degradation of performance. However, one of the first places to tune the server from the out-of-the-box, default configuration is to change the number of internal engine threads allocated within the B2B server. Usually the default configuration for the B2B server engine threads is not suitable for high-volume of messaging loads. So, it is necessary to increase the counts for 3 types of such threads, by specifying the appropriate B2B server properties via the EM console, namely, Inbound - b2b.inboundThreadCount Outbound - b2b.outboundThreadCount Default - b2b.defaultThreadCount The function of these threads are fairly self-explanatory. In other words, the inbound threads process the inbound messages that are coming into the B2B server from an external endpoint. Similarly, the outbound threads processes the messages that are sent out from the B2B server. The default threads are responsible for certain B2B server-specific special tasks. In case the inbound and outbound thread counts are not specified, the default thread count also dictates the total number of inbound and outbound threads. As found in any tuning exercise, the optimisation of these threads is usually reached via an iterative process. The best working combination of the thread counts are directly related to the system infrastructure, traffic load and several other environmental factors.

  • Simple Multiplayer CCG System

    - by TobiHeidi
    I am working on a cross plattform Multiplayer CCG (web, android, ios). Here are my goals in design: I want to game to be easly accessible and understandable for non CCG players within the first minute of play. a single game should be played by 2 - 4 players a once, without problems if one players drops out during play. players should make their next turn simultaneous (without waiting for other to make their turns) My current approach: each Card has a point value for four Elements. In each Turn an Element is (randomly) selected and every Player chooses 1 card out of 3. The Player choosen the card with the highest value for that element wins the Round. After 10 Rounds the players a ranked by how many rounds they won. Why does this approach seems not optimal? It seems really to easy to determin the next best turn. Your own turn is to little affected by the play style of the others. I would love the have a system where some cards are better against other cards. A bit of rock paper scissors where you have to think about what next turn the other players will make or so. But really think freely. I would love to hear ideas may it be additions or new systems to make a CCG with roughly the stated design goals. Thanks

  • Nagios configuration management

    - by HannesFostie
    I am going to implement Nagios (most likely anyway, could turn out to be another tool as well) and I was wondering if anyone would like to share their best practices when it comes to creating, managing and maintaining the config files when it comes to scalability and managability as I find that it might quickly become a real big mess. Any tips, examples or even full configurations would be most welcome and I'd happily look them over. Tools would be welcome as well. Tried out NConf so far, but the generated config files don't seem to do what was promised (not including the parent information for one, and just a PITA to get them working - they generate a ton of errors when checking the config files with the script supplied by nagios) Thanks

  • Automated Error Reporting = More Robust Software

    - by Laila
    I would like to tell you how to revolutionize your software development process </marketing hyperbole> On a more serious note, we (Red Gate's .NET Development team) recently rolled a new tool into our development process which has made our lives dramatically easier AND improved the quality of our software, and I (& one of our developers, Alex Davies) just wanted to take a quick moment to share the love. I work with a development team that takes pride in what they ship, so we take software testing rather seriously. For every development project we run, we allocate at least one software tester for every two developers, and we never ship software without first shipping early access releases and betas to get user feedback. And therein lies the challenge -encouraging users to provide consistent, useful feedback is a headache, but without that feedback, improving the software is. tricky. Until fairly recently, we used the standard (if long-winded) approach of receiving bug reports of variable quality via email or through our support forums. If that didn't give us enough information to reproduce the problem - which was most of the time - we had to enter into a time-consuming to-and-fro conversation with the end-user, to get scrape together the data we needed to work out where the problem lay. As I'm sure you're aware, this is painfully slow. To the delight of the team, we recently got to work with SmartAssembly, which lets us embed automated exception and error reporting into our software with very little pain, and we decided to do a little dogfooding. As a result, we've have made a really handy (if perhaps slightly obvious) discovery: As soon as we release a beta, or indeed any release of software, we now get tonnes of customer feedback through automated error reports. Making this process easier for our users has dramatically increased the amount (and quality) of feedback we get. From their point of view, they get an experience similar to Microsoft's error reporting, and process is essentially idiot-proof. From our side of things, we can now react much faster to the information we get, fixing the bugs and shipping a new-and-improved release, which our users rather appreciate. Smiles and hugs all round. Even more so because, as we're use SmartAssembly's Automated Error Reporting, we get to avoid having to spend weeks building an exception reporting mechanism. It takes just a few minutes to add reporting to a project, and we get a bunch of useful information back, like a stack trace and the values of all the local variables, which we can use to fix bugs. Happily, "Automated Error Reporting = More Robust Software" can actually be read two ways: we've found that we not only ship higher quality software, but we also release within a shorter time. We can ship stable software that our users are happy to upgrade to, and we then bask in the glory of lots of positive customer feedback. Once we'd starting working with SmartAssembly, we were curious to know how widespread error reporting was as a practice. Our product manager ran a survey in autumn last year, and found that 40% of software developers never really considered deploying error reporting. Considering how we've now got plenty of experience on the subject, one of our dev guys, Alex Davies, thought we should share what we've learnt, and he's kindly offered to host a webinar on delivering robust software with Automated Error Reporting. Drawing on our own in-house development experiences, he'll cover how to add error reporting to your program, how to actually use the error reports to fix bugs (don't snigger, not everyone's as bright as you), how to customize the error report dialog that your users see, and how to automatically get log files from your users' machine. The webinar will take place on Jan 25th (that's next week). It's free to attend, but you'll still need to register to hear Alex's dulcet tones.

  • Grid-Based 2D Lighting Problems

    - by Lemoncreme
    I am aware this question has been asked before, but unfortunately I am new to the language, so the complicated explanations I've found do not help me in the least. I need a lighting engine for my game, and I've tried some procedural lighting systems. This method works the best: if (light[xx - 1, yy] > light[xx, yy]) light[xx, yy] = light[xx - 1, yy] - lightPass; if (light[xx, yy - 1] > light[xx, yy]) light[xx, yy] = light[xx, yy - 1] - lightPass; if (light[xx + 1, yy] > light[xx, yy]) light[xx, yy] = light[xx + 1, yy] - lightPass; if (light[xx, yy + 1] > light[xx, yy]) light[xx, yy] = light[xx, yy + 1] - lightPass; (Subtracts adjacent values by 'lightPass' variable if they are more bright) (It's in a for() loop) This is all fine and dandy except for a an obvious reason: The system favors whatever comes first in the for() loop This is what the above code looks like applied to my game: If I could get some help on creating a new procedural or otherwise lighting system I would really appreciate it!

  • Home server - HP Proliant Microserver - Software and setup - OS on USB stick?

    - by Lloyd Watkin
    I've just purchased a HP ProLiant Microserver for home use. I want to set up with web server, samba shares, the usual stuff. My question is really about system setup. It has an internal USB socket so I've attempted to install a copy of Fedora 14 onto it. I turned off X/Gnome, but it still ran like a pig. I've now put the OS on one of the internal disks (250Gb, 7200rpm), but I was wondering if there was a way to utilise the internal USB to give me better power-saving allowing the hard drives to be shut down when not in use. How would you set this server up? I'd rather not go to the extra cost of an SSD right now, but if that's the best way then so be it.

  • Planning home network

    - by gakhov
    I'm planning to setup my home network from scratch and want to ask professional opinions or tips. My home is connected to Internet with a cable connection (100 Mb/s). The devices I would like to connect are VoIP phone (RJ-45), TV (WiFi/LAN), 3 laptops (WiFi), 2 smartphones (WiFi), an iPad (WiFi), a Kindle (WiFi), a network printer and, probably, a home media storage (WiFi/LAN). As you can see, the most load will be on WiFi connections (probably, even if TV supports WiFi it's better to connect it by LAN?). So, I need help to choose the best router (or combination of routers) to support stable connections for all these devices and minimize the total number of routers/adapters. I like how Cisco/Linksys devices were working for me in the past, so preferably (but not obligatorily) I want to setup network with their solutions. Any thoughts?

  • Good free OCR with GUI for correcting mistakes? (for Windows)

    - by Hugh Allen
    I've used SimpleOCR, which has a nice GUI for correcting mistakes. Unfortunately it makes a lot of mistakes! (and suffers other bugs and limitations) On the other hand Tesseract is more accurate but has no GUI at all. Is there a free OCR program for Windows which has a nice GUI and a low error rate? I want it to highlight suspect words (by OCR uncertainty, not just spell checking) and show the original (bitmap) word while I'm editing the OCRed word similar to what SimpleOCR does. Open-source would be best, followed by freeware, then trial / demo / crippleware a long way behind.

  • XNA C# Platformer - physics engine or tile based?

    - by Hugh
    I would like to get some opinions on whether i should develop my game using a physics engine (farseer physics seems to be the best option) or follow the traditional tile-based method. Quick background: - its a college project, my first game, but have 4 years academic programming experience - Just want a basic platformer with a few levels, nothing fancy - want a shooting mechanic, run and gun, just like contra or metal slug for example - possibly some simple puzzles I have made a basic prototype with farseer, the level is hardcoded with collisions and not really tiled, more like big full-screen sized tiles, with collision bodies drawn manually along the ground and walls etc. My main problem is i want a simple retro feel to the jumping and physics but because its a physics simulation engine its going to be realistic, whereas typical in air controllable physics for platformers arent realistic. I have to make a box with wheel body fixture under it to have this effect and its glitchy and doesnt feel right. I chose to use a physics engine because i tried the tile method initially and found it very hard to understand, the engine took care of alot things to save me time, mainly being able to do slopes easily was nice and the freedom to draw collision bounds wherever i liked, rather then restricted to a grid, which gave me more freedom for art design also. In conclusion i don't know which method to pick, i want to use a method which will be the most straight forward way to implement and wont give me a headache later on, preferably a method which has an abundance of tutorials and resources so i dont get "stuck" doing something which has been done a million times before! Let me know i haven't provided enough information for you to help me! Thanks in advance, Hugh.

  • video streaming infrastructure advice

    - by Alchemical
    We would like to set-up a live video-chat web site and are looking for basic recomendations for software and hardware set-up. Most streams will be broadcast live from a single person with a web cam, etc., and viewed by typically 1-10 people, although there could be up to 100+ viewers on the high side. Audio and video do not have to be super-high quality, but do need to be "good enough". The main point is to convey the basic info in the video (and audio). If occasionally the frame-rate drops low and then goes back to normal fairly soon, we could live with that. Budget is an issue, so we are in general looking for a lower cost solution that will give us most of what we need in temers of performance and quality. We are looking at Peer1 for co-lo. The rest of our web site will be .Net / Windows platform. We are open to looking at any platform for the best streaming solution, although our technical expertise is currently more on the Windows side.

  • CruiseControl.Net - not able to see Project Statistics

    - by Anders Juul
    Hi all, I've made a reinstallation of the buildserver and can no longer see the standard graphs of project statistics. The error message shown is "Missing/Invalid statistics reports. Please check if you have enabled the Statistics Publisher, and statistics have been collected atleast once after that." To the best of my knowledge, the ccnet.config file has not been changed in this respect and by inspection it is verified that I have a Statistics / statisticsList-section for the project. Furthermore, the values appear in the Artifacts\statistics.csv and Artifacts\report.xml files. My guess would then be StatisticsGraph.xslt, which I have copied fresh from distribution to both Server\xlst and WebDashboard\xslt (why are they located in both places, by the way!?). Rebuild and check - still same error message. Any hints to how to debug this would be appreciated!

  • How to retain background colors when pasting between documents in Excel

    - by Iain Fraser
    I have a script that programatically generates excel spreadsheets - cleaning up ugly reports that are given to us from another organisation. For interests sake; I'm using PHPExcel to generate the "clean" reports. We get these reports every week for an event that happens every couple of months. The reports contain a list of attendees along with a group id that allows us to know that some attendees belong together. To help the event organisers out, I've taken the event ID and generated a unqiue color code (based on the hash of the event ID - truncated to 6 characters). This unique colour code is set as the background color of a cell in each row. This helps organisers quickly visually identify group members. Trouble is, when the organisers copy the rows from the weeks report into the master report (which contains all attendees, not just the ones that signed up this week) - all the colour-codes snap to the master template's color pallette. Thank you very much for your time All the best Iain

  • Basic Connections Through Socket Server

    - by Walrus
    I'm designing a simple 2 player RTS with Stencyl, a program that uses blocks for coding. The current code updates lists whenever an actor moves (new X and Y), and I'd want the server to update the game state with each change to the list. However, to start off: I don't even know how to set up a socket server. Stencyl has taught me the basics of logic, but I've yet to learn any programming languages. I've downloaded a Smartfox 2X socket server that I'm intending to use. Right now I'm only looking to make baby steps; I want to do something to this effect: "When someone connects to the server, open insert file here". How can I do this? My intention is to have this file be the game client. Is this "open file when connected" method the best way to go about this? When answering: assume that I know nothing, because really, though I have done research (I know that UDPTCP for real time), implementation-wise I know nothing.
