• Theory Of A Weird Thought - Forms Submission

  - by user2738336

  In theory, if you were to open two computers that were perfectly synced together on a website that has a form. This form has fields where say for example the username has to be unique. Assuming both computers have the same information on the form, and in theory let's say that the submit button was pressed at the same time, and that these two computers have the exact same build and internet speed and the same response time from the server, whose information would be submitted to the database and whose information would be denied knowing the username field is unique.

• What makes a great place to work

  - by Rob Farley

  Co-incidentally, I’ve been looking for office space for LobsterPot Solutions during the same few days that Luke Hayler ( @lukehayler ) has asked for my thoughts (okay, he ‘tagged’ me) on what makes a great place to work .

  I'm looking into the best way to deploy a customized Ubuntu image and it looks like I have two options: To make an "OEM install" version To make a custom Ubuntu image Could someone help me understand the difference between these two methods of customizing a Ubuntu install?

• Editing /.config/dconf/user

  - by user86322

  I am having a problem with Gnome3 (actually, I have it set to fallback mode, or Gnome 2). I have two displays and I need an X screen (I used nvidia-xconfig and nvidia-settings to do this) for each screen. However, every time I either restart X or log in, Gnome seems to be adding the objects values under /gnome/gnome-panel/layouts (ex. first time I set the two separate X screens I had clock, then log out/in, there was clock and clock1 under objects, and then log out/in there were three, clock, clock1, clock2,.......log out/in, ............30 times....clock, clock1, clock2, ......clock 42.....!! The same thing goes for top-panels, menu-bars, etc.) After a while, I found out I could remove all those using the dconf-editor, going to /gnome/gnome-panel/layouts, removing all the repetitions under fields objects-id-list and top-id-list and leaving one value of each object. This is not a solution but at least allow me to keep using Linux without so much problem. However, the problem persists every time I restart X or log in. I now finally learned about "dconf" and where the user profile settings are located (~/.config/dconf/user) and one can use "dconf" to see the keys. In my case, I need to change/remove many keys (all those clocksX, workspace-X, menu-bar-X, etc., where goes from 1 to 42 and still counting) so it's really tedious and boring to be changing one by one using "dconf write". So I found "dconf dump", which actually allow me to dump everything into a .txt file and edit the file really quick (i.e, "dconf dump / >> dump_user.txt"). The problems? Two of them: How do I "load" back "dump_user.txt" I edited into the user profile? (I read somewhere there was a "dconf reload" but reload doesn't exist as a command under "dconf") How do I stop Gnome from keep adding more objects to my desktop environment every time I log in/restart X? NOTE: The problem doesn't occur when I set the displays to use TwinView feature (i.e., the desktop is extended/shared by both displays). However, for my case I need two separate X's. Any help/suggestion would be greatly appreciated. Thanks

• What different ways are there to model restitution in a physics engine?

  - by Mikael Högström

  In my physics engine I give a body a value for restitution between 0 and 1. When two bodies collide there seems to be different views on how the restitution of the collision should be calculated. To me the most intuitive seems to be to take the average of the two but some seem to take only the largest one. Are there other ways to do it? Also, could the closing velocity or some other parameter come into effect?

• Synchronise Database between servers via php [closed]

  - by Emmanuel

  Hi Guys, I'm needing to synchronise two mysql databases between different servers on a regular basis, by a client-initiated interface. I've been doing it by remote MYSQL connection, and adding the IP of the servers to the whitelist for MYSQL remote connections. Problem is however, that the client has a dynamic IP, so as soon as it changes they can no longer sync. So I'm trying to find an alternative way of synchronising the two databases via some sort of secure php script.

• Real-Time Multi-User Gaming Platform

  - by Victor Engel

  I asked this question at Stack Overflow but was told it's more appropriate here, so I'm posting it again here. I'm considering developing a real-time multi-user game, and I want to gather some information about possibilities before I do some real development. I've thought about how best to ask the question, and for simplicity, the best way that occurred to me was to make an analogy to the field (or playground) game darebase. In the field game of darebase, there are two or more bases. To start, there is one team on each base. The game is a fancy game of tag. When two people meet out in the field, the person who left his base most recently timewise captures the other person. They then return to that person's base. Play continues until everyone is part of the same team. So, analogizing this to an online computer game, let's suppose there are an indefinite number of bases. When a person starts up the game, he has a team that is located at, for example, his current GPS coordinates. It could be a virtual world, but for sake of argument, let's suppose the virtual world corresponds to the player's actual GPS coordinates. The game software then consults the database to see where the closest other base is that is online, and the two teams play their game of virtual tag. Note that the user of the other base could have a different base than the one run by the current user as the closest base to him, in which case, he would be in two simultaneous battles, one with each base. When they go offline, the state of their players is saved on a server somewhere. Game logic calls for the players to have some automaton-logic of some sort, so they can fend for themselves in a limited way using basic rules, until their user goes online again. The user doesn't control the players' movements directly, but issues general directives that influence the players' movement logic. I think this analogy is good enough to frame my question. What sort of platforms are available to develop this sort of game? I've been looking at smartfoxserver, but I'm not convinced yet that it is the best option or even that it will work at all. One possibility, of course, would be to roll out my own web server, but I'd rather not do that if there is an existing service out there already that I could tap into. I will be developing for iOS devices at first. So any suggestions would be greatly appreciated. I think I need to establish the architecture first before proceeding with this project. Note that darbase is not the game I intend to implement, but, upon reflection, that might not be a bad idea either.

• Anyone know a way to find out the number of Twitter followers for a particular account on any given date?

  - by mejpark

  I manage two corporate Twitter accounts and two personal Twitter accounts, and it would be really useful to know how many followers each account has at the end of each week. I'm using TweetStats.com to gather statistics at the moment, but the follower stats functionality isn't granular enough to determine the precise number of followers. Does anyone know of any useful and free tools that can provide the exact number of followers for a specific Twitter account on any given date? Thank you, Mike.

• How do I disable mouse magnet on middle edge with multi monitors?

  - by piquadrat

  I use Ubuntu 12.04 on a two screen setup. Multiscreen on 12.04 has generally become much better, but there is one thing that really gets on my nerves: there's a mouse magnet of sorts on the middle edge (between the two screens). It's undoubtedly there to make it easier to interact with the launcher on the right screen. But I have enough trust in my mousing skills, the magnet is more annoying than helpful in my case. Can I disable it somehow?

• What is a good design model for my new class?

  - by user66662

  I am a beginning programmer who, after trying to manage over 2000 lines of procedural php code, now has discovered the value of OOP. I have read a few books to get me up to speed on the beginning theory, but would like some advice on practical application. So,for example, let's say there are two types of content objects - an ad and a calendar event. what my application does is scan different websites (a predefined list), and, when it finds an ad or an event, it extracts the data and saves it to a database. All of my objects will share a $title and $description. However, the Ad object will have a $price and the Event object will have $startDate. Should I have two separate classes, one for each object? Should I have a 'superclass' with the $title and $description with two other Ad and Event classes with their own properties? The latter is at least the direction I am on now. My second question about this design is how to handle the logic that extracts the data for $title, $description, $price, and $date. For each website in my predefined list, there is a specific regex that returns the desired value for each property. Currently, I have an extremely large switch statement in my constructor which determines what website I am own, sets the regex variables accordingly, and continues on. Not only that, but now I have to repeat the logic to determine what site I am on in the constructor of each class. This doesn't feel right. Should I create another class Algorithms and store the logic there for each site? Should the functions of to handle that logic be in this class? or specific to the classes whos properties they set? I want to take into account in my design two things: 1) I will add different content objects in the future that share $title and $description, but will have their own properties, so, I want to be able to easily grow these as needed. 2) I will add more websites constantly (each with their own algorithms for data extraction) so I would like to plan efficienty managing and working with these now. I thought about extending the Ad or Event class with 'websiteX' class and store its functions there. But, this didn't feel right either as now I have to manage 100s of little website specific class files. Note, I didn't know if this was the correct site or stackoverflow was the better choice. If so, let me know and I'll post there.

• Is there a library that handles hexagon tiled 2D maps?

  - by Pete Mancini

  It would represent a map that is semi-square of arbitrary size. It would have a simple system for representation of the map coordinates such as 0101 (first column, 1st hex). I'd want the map to be able to tell me the distance between two points, and what other hexes lay between those two points as a list or array. I don't care as much about the language but c# or python would be ideal. Does one exist?
