• Not allowed to upload .HTML files to my own DNN Site: Is it normal?

  - by Jake M

  My Question: Our webhost provider wont make it so we can upload .html files to our DNN site trhough the DNN File Manager page. Is that normal, should I push them to allow me to do this? We have recently transferred our website to a Dot Net Nuke run website. We originally had our website on a Linux server with Python scripts handling the backend. Obviously we now have a Windows server running .NET with ASP .NET code on the backend. Our webhost is a local Australian company. And they are saying we cant upload any .html files to the main part of the server, ie, www.ourdomain.com/Portals/0/. They are saying that the only place I can upload .html files is via FTP to this folder *www.ourdomain.com/Portals/0/html_content* This is a major problem for me because I am trying to upload my own skin which means I need to upload a main.html file to www.ourdomain.com/Portals/0/skins/myskin/ but they wont let me?! I guess what I am asking is, is this normal practice, why would they not allow this? As an experienced web admin for Linux servers and as someone who is used to being able to do whatever I want on my OWN server this is someing that really pis$%s me off!

• Best practice for designing a risk-style board game

  - by jyanks

  I'm just trying to figure out how to set up the code for a game like risk... I would like it to be extensible, so that I can have multiple maps (ie- World, North America, Eurasia, Africa) so hardcoding in the map doesn't seem to make a whole lot of sense I'm a bit confused on how/where items should be stored/accessed. Here are the objects I see the game theoretically using: -Countries/Territories -Cities (Can be contained within territories) -Capitols -Connections -Continents -Map -Troops At the moment, I feel like: -A map should have a list of continents and countries. The continents would be more of a 'logical' thing where the continents would just be lists of countries that are checked for bonuses at the start of turns -Countries should have a list of countries that they're connected to for the connections What I can't figure out is: Where do I store the troops? Do I have an object for every single troop or do I just store the number of troops on a country object as an integer? What about capitols and cities? Do those just have a reference to the country they reside in? Is there anything I'm not seeing here that's going to screw me over in the long run with the way that I'm thinking about things now? Any advice would be appreciated.

• How do I create my own programming language and a compiler for it

  - by Dave

  I am thorough with programming and have come across languages including BASIC, FORTRAN, COBOL, LISP, LOGO, Java, C++, C, MATLAB, Mathematica, Python, Ruby, Perl, Javascript, Assembly and so on. I can't understand how people create programming languages and devise compilers for it. I also couldn't understand how people create OS like Windows, Mac, UNIX, DOS and so on. The other thing that is mysterious to me is how people create libraries like OpenGL, OpenCL, OpenCV, Cocoa, MFC and so on. The last thing I am unable to figure out is how scientists devise an assembly language and an assembler for a microprocessor. I would really like to learn all of these stuff and I am 15 years old. I always wanted to be a computer scientist some one like Babbage, Turing, Shannon, or Dennis Ritchie. I have already read Aho's Compiler Design and Tanenbaum's OS concepts book and they all only discuss concepts and code in a high level. They don't go into the details and nuances and how to devise a compiler or operating system. I want a concrete understanding so that I can create one myself and not just an understanding of what a thread, semaphore, process, or parsing is. I asked my brother about all this. He is a SB student in EECS at MIT and hasn't got a clue of how to actually create all these stuff in the real world. All he knows is just an understanding of Compiler Design and OS concepts like the ones that you guys have mentioned (ie like Thread, Synchronisation, Concurrency, memory management, Lexical Analysis, Intermediate code generation and so on)

• Google analytics - drop in traffic

  - by user1001421

  Bit of a general question here. We are in the process of converting a number of our clients from older web sites to new ones. The problem we are getting, and sorry for being so general here, is we are getting a sharp decline in traffic as reported on Google Analytics. It's not a gradual decline, it seems to hit almost as soon as the new site goes live. I've just got a few questions to see if there is something we are doing wrong: a) We are using the same analytics accounts going from old to new site. Is this a bad idea? b) The actual analytics code is integrated into the pages using a server-side include. IS this a bad idea? c) We structure our sites differently to our old site. IE. The old sites would pretty must have all the web pages in the root directory, and hyperlinks would be linked to the page files: EG. <a href="somepage.aspx">Link</a> Our new sites now have a directory structure that pretty much reflects the navigation structure, and hyper links link to the pages directory instead of the actual page: EG. <a href="/new-items/shoes/">New shoes</a> Is this a bad idea. I'm really searching for a needle in a haystack here. Would appriciate any help or advice as to why we are getting such a sharp and sudden drop in traffic. Again, so this is such a general question. Thanks in advance.

• Real-time stock market application

  - by Sam

  I'm an amateur programmer. I'd like to develop a software application (like Tradestation), to analyse real-time market data. Please teach me if the following approach is correct, ie the procedures, knowledge or software needed etc: Use a DB to read the real-time feed from data provider: what should be the right DB to use? I know it should be a time serious one. Can I use SQL, Mysql, or others? What database can receive real-time data feed? Do I need to configure the DB to do this? If the real-time data is in ASCII form, how can it be converted to those that can be read by the DB and my application? Should I have to write codes or just use some add-ins? What kind of add-in are needed? How should I code the program to retrieve the changing data from the DB so that the analysis software screen data can also change asynchronously? (like the RTD in excel) Which aspects of programming do I need to learn to develop the above? Are there web resources/ books I can refer to for more information?

• Help setting up wireless in Ubuntu 13.04

  - by James

  I'm having problems connecting my WIFI in Ubuntu 13.04 . So I was wondering if filling in the data manually ie: the IPv4, IPv6, the SSID and BSSID info etc. I did try this before but maybe I put in the wrong data or maybe not enough. Would that make it work? I just don't know how to find out some of the data you need to put in? I'm new and it's confusing. Does anyone know the solution?

• What functionality should a (basic) mock framework have?

  - by user1175327

  If i would start on writing a simple Mock framework, then what are the things that a basic mock framework MUST have? Obviously mocking any object, but what about assertions and perhaps other things? When I think of how I would write my own mock framework then I realise how much I really know (or don't know) and what I would trip up on. So this is more for educational purposes. Of course I did research and this is what i've come up with that a minimal mocking framework should be able to do. Now my question in this whole thing is, am I missing some important details in my ideas? Mocking Mocking a class: Should be able to mock any class. The Mock should preserve the properties and their original values as they were set in the original class. All method implementations are empty. Calls to methods of Mock: The Mock framework must be able to define what a mocked method must return. IE: $MockObj->CallTo('SomeMethod')->Returns('some value'); Assertions To my understanding mocking frameworks also have a set of assertions. These are the ones I think are most important (taken from SimpleTest). expect($method, $args) Arguments must match if called expectAt($timing, $method, $args) Arguments must match when called on the $timing'th time expectCallCount($method, $count) The method must be called exactly this many times expectMaximumCallCount($method, $count) Call this method no more than $count times expectMinimumCallCount($method, $count) Must be called at least $count times expectNever($method) Must never be called expectOnce($method, $args) Must be called once and with the expected arguments if supplied expectAtLeastOnce($method, $args) Must be called at least once, and always with any expected arguments And that's basically, as far as I understand, what a mock framework should be able to do. But is this really everything? Because it currently doesn't seem like a big deal to build something like this. But that's also the reason why I have the feeling that i'm missing some important details about such a framework. So is my understanding right about a mock framework? Or am i missing alot of details?

• Installation problems with Gimp 2.8 on Kubuntu 12

  - by Martyn

  I've just upgraded to Kubuntu 12.04 and having problems installing Gimp 2.8, I was wondering if anyone can help me? I've followed these instructions: sudo add-apt-repository ppa:otto-kesselgulasch/gimp sudo apt-get update sudo apt-get install gimp but get this error: The following packages have unmet dependencies. gimp : Depends: libwebkitgtk-1.0-0 (>= 1.3.10) but it is not going to be installed E: Unable to correct problems, you have held broken packages. I've tried running these and trying again with the same problems: sudo apt-get clean sudo apt-get autoremove sudo apt-get update sudo apt-get upgrade sudo apt-get -f install also running sudo apt-get install libwebkitgtk-1.0-0 gives me this error The following packages have unmet dependencies. libwebkitgtk-1.0-0 : Depends: libgail18 (>= 1.18.0) but it is not going to be installed E: Unable to correct problems, you have held broken packages. and then running sudo apt-get install libgail18 gives me this error The following packages have unmet dependencies. libgail18 : Depends: libgtk2.0-0 (= 2.24.10-0ubuntu6) but 2.24.10-1oneiric6~ppa is to be installed E: Unable to correct problems, you have held broken packages.

• Erlang node acts like it connects, but doesn't [migrated]

  - by Malfist

  I'm trying to setup a distributed network of nodes across a few firewalls and it's not going so well. My application is structured like this: there is a central server that always running a node ([email protected]) and my co-worker's laptops connect to it on startup. This works if we're all in the office, but if someone is at home, they can connect to the masternode, but they fail to connect to the other nodes in the swarm. I.E., erlang fails to gossip correctly. To correct this, I've change epmd's port number and changed the inet_dist_listen ports to a known open port (1755 and 7070 respectively). However, something fishy is going on. I can run net_adm:world() and it reports that it connects to master node, but when I run nodes() I get an empty array. Same with net_adm:ping('[email protected]'). See: Eshell V5.9 (abort with ^G) ([email protected])1> net_adm:world(). ['[email protected]'] ([email protected])2> nodes(). [] ([email protected])3> net_adm:ping('[email protected]'). pong ([email protected])4> nodes(). [] ([email protected])5> What's going on, and how can I fix it?

• Database Backup History From MSDB in a pivot table

  - by steveh99999

  I knocked up a nice little query to display backup history for each database in a pivot table format.I wanted to display the most recent full, differential, and transaction log backup for each database. Here's the SQL :-WITH backupCTE AS (SELECT name, recovery_model_desc, d AS 'Last Full Backup', i AS 'Last Differential Backup', l AS 'Last Tlog Backup' FROM ( SELECT db.name, db.recovery_model_desc,type, backup_finish_date FROM master.sys.databases db LEFT OUTER JOIN msdb.dbo.backupset a ON a.database_name = db.name WHERE db.state_desc = 'ONLINE' ) AS Sourcetable   PIVOT (MAX (backup_finish_date) FOR type IN (D,I,L) ) AS MostRecentBackup ) SELECT * FROM backupCTE Gives output such as this :-  With this query, I can then build up some straightforward queries to ensure backups are scheduled and running as expected -For example, the following logic can be used ;-  - WHERE [Last Full Backup] IS NULL) - ie database has never been backed up.. - WHERE [Last Tlog Backup] < DATEDIFF(mm,GETDATE(),-60) AND recovery_model_desc <> 'SIMPLE') - transction log not backed up in last 60 minutes. - WHERE [Last Full Backup] < DATEDIFF(dd,GETDATE(),-1) AND [Last Differential Backup] < [Last Full Backup]) -- no backup in last day.- WHERE [Last Differential Backup] < DATEDIFF(dd,GETDATE(),-1) AND [Last Full Backup] < DATEDIFF(dd,GETDATE(),-8) ) -- no differential backup in last day when last full backup is over 8 days old.

• Cannot access personal website from home IP. More details inside.

  - by GX67

  This is a recent problem I've been having. My site can be accessed from almost everywhere else except from my home IP, where I do most of my editing/updating, etc. I've tested my connection from my school's network, a friend's connection from out of state (multiple states), and through a tethered connection with my friend's Android. It works in all those cases, both viewing, accessing the cPanel, and using FTP. Here's the problem that happens to me when I try to view it from my home IP: The page times out in Firefox, IE, and Chrome. Using the cmd, I ran tracert and ping, both as failed attempts. Log here. downforeveryoneorjustme.com says my site is up. So do the other site checkers. I can't access my cPanel or FTP accounts. I can't access the host site. (I use perfectz.info for hosting, and I can't access their site either.) System settings: No firewall enabled. Ports are seemingly properly forwarded. (e.g. The ports are open in the router settings, and are open everywhere else.) I have an email forwarder set up from the cPanel that works just fine. (i.e. I can receive emails sent to that address. If any other information is needed, I'll do my best to provide it. UPDATE @ilhan: I use two things: 1) The site cPanel from in-browser. 2) Dreamweaver CS5 FTP. @Matthias: I tested both, and it passes the dual stack with a 10/10. What should I do then?

• The overlooked OUTPUT clause

  - by steveh99999

  I often find myself applying ad-hoc data updates to production systems – usually running scripts written by other people. One of my favourite features of SQL syntax is the OUTPUT clause – I find this is rarely used, and I often wonder if this is due to a lack of awareness of this feature.. The OUTPUT clause was added to SQL Server in the SQL 2005 release – so has been around for quite a while now, yet I often see scripts like this… SELECT somevalue FROM sometable WHERE keyval = XXX UPDATE sometable SET somevalue = newvalue WHERE keyval = XXX -- now check the update has worked… SELECT somevalue FROM sometable WHERE keyval = XXX This can be rewritten to achieve the same end-result using the OUTPUT clause. UPDATE sometable SET somevalue = newvalue OUTPUT deleted.somevalue AS ‘old value’,              inserted.somevalue AS ‘new value’ WHERE keyval = XXX The Update statement with output clause also requires less IO - ie I've replaced three SQL Statements with one, using only a third of the IO.  If you are not aware of the power of the output clause – I recommend you look at the output clause in books online And finally here’s an example of the output produced using the Northwind database…

• Unicode license

  - by Eric Grange

  Unicode Terms of use (http://www.unicode.org/copyright.html) state that any software that uses their data files (or a modification of it) should carry the Unicode license references. It seems to me that most Unicode libraries have functions to check if a character is a digit, a letter, a symbol, etc. ans so will contain a modification of the Unicode Data Files (usually in the form of tables). Does that mean the license applies and all applications that use such Unicode libraries should carry the license? I've checked around, and it appears very few Unicode software do carry the license, though arguable most of those that didn't carry the license were from companies that were members of the Unicode consortium (do they get license exemption?). Some (f.i. Mozilla) are only "Liaison Members", and while their software do not carry the license (AFAICT), they do obviously rely on data derived from those data files. Is Mozilla in breach of the license? Should we carry the license in all apps that include any form of advanced Unicode support? (ie. are bound to rely on the Unicode data files) Or is there some form of broad exemption? (since very very few software out there carries the license)

• Estimate of Hits / Visits / Uniques in order to fall within a given Alexa Tier?

  - by Alex C

  I was wondering if anyone could offer up rough estimates that could tell me how many hits a day move you into a given Alexa rank ? Top 5,000 Top 10,000 Top 50,000 Top 100,000 Top 500,000 Top 1,000,000 I know this is incredibly subjective and thus the broad brush strokes with the number ranges... BUT I've got a site currently ranked just over 1.2M worldwide and over 500k in the USA (http://www.alexa.com/siteinfo/fstr.net) Pretty cool for something hand-built on weekends (pat self on back) I was applying to an ad-platform and was told that their program doesn't accept webmasters who have an Alexa rank of greater than 100,000. (Time to take back that pat on the back I guess). I know that my hits in the last 30 days are somewhere on the order of 15,000 uniques and 20,000 pageviews. So I'm wondering how much harder do I have to work to achieve my next "goals"? I'd like to break into the top million, then re-evaluate from there. It'd be nice to know what those targets translate into (very roughly of course). I imagine that alexa ranks and tiers become very much exponential as you move up the ranks, but even hearing annecdotal evidence from other webmasters would be really useful to me. (ie: I have a site that is ranked X and it got Y hits in the last 30 days) Thanks :) - Alex

• Naming your website longname.com vs shortcatchy.net vs shortcatchy.info

  - by jskye

  I'm designing a website that will basically be a social network for sharing information. I have the domain $$$$d.net and the same domain $$$$d.info where $$$$ is a word (that runs into the d) pertaining to the purpose of the site . The .com of this domain was already taken, but they've got nothing showing. They only have a not reached google error showing ie. dont seem to be trying to sell it either. I also have the long name of the site $$$$------&&&&&&&&&.com where the words $$$$ and &&&&&&&&& would contribute relevant seo to the site. In fact the word $$$$------ would also if a one letter spelling mistake is recognised at all by google, which i doubt but am unsure about. But as a brandname the $$$$------ word still works relevantly. Which do you think is a better choice to use? The short catchy name with the .info for relevance to information The .net which is more familiar than .info but slightly less relevant maybe. (But i think net as in network still works cos as i said it will be a social networking site). The long, .com domain which has more SEO plus a pun albeit on a spelling mistake. I know its kind of a subjective question and also hard to answer without knowing the name (which I've obfuscated because I'm only in initial design stage) but nevertheless im interested in what some of you guys think.

• How to handle fine grained field-based ACL permissions in a RESTful service?

  - by Jason McClellan

  I've been trying to design a RESTful API and have had most of my questions answered, but there is one aspect of permissions that I'm struggling with. Different roles may have different permissions and different representations of a resource. For example, an Admin or the user himself may see more fields in his own User representation vs another less-privileged user. This is achieved simply by changing the representation on the backend, ie: deciding whether or not to include those fields. Additionally, some actions may be taken on a resource by some users and not by others. This is achieved by deciding whether or not to include those action items as links, eg: edit and delete links. A user who does not have edit permissions will not have an edit link. That covers nearly all of my permission use cases, but there is one that I've not quite figured out. There are some scenarios whereby for a given representation of an object, all fields are visible for two or more roles, but only a subset of those roles my edit certain fields. An example: { "person": { "id": 1, "name": "Bob", "age": 25, "occupation": "software developer", "phone": "555-555-5555", "description": "Could use some sunlight.." } } Given 3 users: an Admin, a regular User, and Bob himself (also a regular User), I need to be able to convey to the front end that: Admins may edit all fields, Bob himself may edit all fields, but a regular User, while they can view all fields, can only edit the description field. I certainly don't want the client to have to make the determination (or even, for that matter, to have any notion of the roles involved) but I do need a way for the backend to convey to the client which fields are editable. I can't simply use a combination of representation (the fields returned for viewing) and links (whether or not an edit link is availble) in this scenario since it's more finely grained. Has anyone solved this elegantly without adding the logic directly to the client?

• Fix a jQuery/HTML5 dynamic content issue by upgrading jQuery

  - by Steve Albers

  The default NuGet template for MVC3 pushes down jQuery 1.5.1.  You can upgrade to a new version (1.7.1 is current when this is written) to avoid a problem with the creation of “unknown” HTML5 tags in IE6-8: Take this sample HTML page using HTML5Shiv to provide support for new HTML5 tags in IE6 – IE8.  The page has a number of <article> tags that are backwards compatible in Internet Explorer 6-8 thanks to the HTML5Shiv. After the article elements there is a jQuery 1.5.1 script tag, and a ready() event handler that appends a footer element with a copyright to each of the article tags.  This appears correctly in IE9, but in older IE browsers the unknown tag problem reappears for the dynamic <footer> elements, even though we have the HTML5Shiv at the top of the page.  The copyright text sits outside of the two separate footer tags. To solve the issue upgrade your jQuery files to an up-to-date version.  For instance in Visual Studio 2010: In the Solution Explorer right click on References and choose Manage NuGet Packages. In the Manage NuGet Packages window select the jQuery item on the middle of the page and click the “Upgrade” button. You may need to upgrade your script src references to point at the new version. Using the updated jQuery library the incorrect tags should disappear and styles should work properly:   You can find more information about the issue on the jQuery Bug Tracker site.

• What are my choices for server side sandboxed scripting?

  - by alfa64

  I'm building a public website where users share data and scripts to run over some data. The scripts are run serverside in some sort of sandbox without other interaction this cycle: my Perl program reads from a database a User made script, adds the data to be processed into the script ( ie: a JSON document) then calls the interpreter, it returns the response( a JSON document or plain text), i save it to the database with my perl script. The script should be able to have some access to built in functions added to the scripting language by myself, but nothing more. So i've stumbled upon node.js as a javascript interpreter, and and hour or so ago with Google's V8(does v8 makes sense for this kind of thing?). CoffeeScript also came to my mind, since it looks nice and it's still Javascript. I think javascript is widespread enough and more "sandboxeable" since it doesn't have OS calls or anything remotely insecure ( i think ). by the way, i'm writing the system on Perl and Php for the front end. To improve the question: I'm choosing Javascript because i think is secure and simple enough to implement with node.js, but what other alternatives are for achieving this kind of task? Lua? Python? I just can't find information on how to run a sandboxed interpreter in a proper way.

• How can I make myself better at programming working at a shi* job ?

  - by Scrooge

  I recently graduated with an Engineering degree in Computer Science, but my employer (a mid-sized software company) is not using my logical and programming skills. I want to move to a better opportunity but how do I do that since my experience here is not going to count as much? How do I get a better programming job? The worst part is that I am still reading from books (and not writing code myself) even after I have started working. They are paying me a standard entry level Indian IT job rate but I really dont care. It's not worth it. Please advise as to how I can do something worthwhile. (I have studied C++; Core Java; Ruby On Rails ..made a couple of academic projects but no relevant practical real world experience). Just to make things easier .. let me list a few basic queries How I get better at programming without a good project at my company? Please suggest projects where I can learn to write practical code (platform doesn't matter) Best place to take part in open source development? Is it possible that I earn slightly more while I learn? (apart from my sh** job I mean) What kind of practical projects are best suited for me? (ie for an entry level programmer)

• Please, tell us how you made Agile work for you?

  - by Paul

  I've been seeing many questions related to Agile. There seems to be confusion between the people who are doing Agile successfully, and those of us who don't understand it. So I'm wondering if some of the successful teams would be willing to give the result of us some examples of how you succeeded. Some of the things I know I wonder What steps did you use? (ie. Talk to users, mock up, tests, code, testing, (whatever)) Tools that helped you? Did you generate any artifacts, other than a working implementation? How did you prevent spaghetti architecture / code? How do you pass along to new team members, or is the team stable for the project How did you determine exit criteria, or was it open ended. (Scope of project?) Did you do this as contracting? How did you develop a contract up-front? Did the business do any up front work? Or did they come to the table with "We want to implement a "bleh bleh blah"? What types of tests did you use? Unit, Integration, UAT? Or did the process make some/all of those unnecessary? Bonus: Do you have an situations / links to "How To" Agile articles, books, etc? Wiki, describes what but not how (to the uninitiated) At least to me, not a duplicate

  I have an arbitrary number of tables with an arbitrary number of rows in each, and all tables are the same height. My initial approach was to just set the overall height of the table and hope the rows were smart enough to distribute themselves appropriately. That's not the case. I have 4 different behaviors going on with 4 browsers, but I need them to all render at the very least in a similar way. Safari & Chrome (WebKit): All rows are equal height, creating scroll bars as needed and fitting within table height. Firefox: All rows are the height necessary to fit their content, with the remaining rows overflowing out of the table. Additionally, If the content of the rows does not take up all of the height, only the part of the table with content in it takes the background (though it seems, through use of Firebug, that the actual table [and TR] extend to the bottom of the proper table height). IE: All rows are the height necessary to fit their content, with the remaining rows overflowing out of the table. Obviously this only includes one version of each browser and additional variation would likely appear with more being tested. Ideally, a solution where the browser renders TRs with less content smaller than those with larger content, while still using scrolling within the variable height TRs when the overall height of the table is not enough would be optimum. I could potentially see a solution to achieve that with JS, but can it be done with CSS? Or, if not, can the behavior that WebKit displays be made to work across the browsers? Thanks! PS: Example can be found here.

• Storing data offline with javascript

  - by Walker

  My question is about storing data offline and potentially whether I will need to bring in an outside programmer or could this be learned within a few weeks? The website I am working on will have an interface where users will login and go through a series of quizzes in the form of checkbox, drop down menus, and others. Each page/quiz area could have 20-100 total checkboxes in a series of 3-5 rows because of the comprehensive nature of course. This I can do - I know how to code the quiz and return a correct or incorrect answer based on each individual checkbox and present a cumulative score (ie: you got 57% correct). The issue lies in the fact that I would like to save the users results and keep them informed of their progress. When they complete all of the quizzes, I would like to have a visual output of their performance in each area. Storing the output from their results offline is where I think I may run into a problem with my lack of coding experience. I would also like to have a sidebar with their progress of each section (10-15) with a green percentage completion bar or a % correct which would draw from this. I have never had to code something that stores information like this offline - so back to my question - would it be better to learn the language needed or bring in a coder/developer for the back end stuff.

• Is it possible to use 3G internet for a TCP/IP game server?

  - by Amit Ofer

  I'm working on a turned based multiplayer android game with a friend. I started working on the game server and client using socket programming. I found a few tutorials on how to implement a basic chat on android and I started extending that example to suit my needs. Basically the game is really simple and the communication only include sending a few string from the client to the server every turn and sending the calculated scores back to all the clients after each turn. the idea is that one of the players creates the game and thus initialize the server, and each player connects to this client using ip. I tried this solution and it seems to work great when all the players are using the same wifi connection or by using router port forwarding. The problem is when trying to use 3G internet for the server, I guess the problem is that 3G ip address isn't global and you can't use port forwarding there, correct me if I'm wrong here. Is there a way to overcome this issue? or the only solution is to limit my game to wifi only or think of a different solution than the standard socket programming solution? I.E web server etc. what do you think would be the best approach here? Thanks.

• Ubiquitous Language and Custom types

  - by EdvRusj

  Note that my question is referring to those attributes that even on their own already represent a concept ( ie on their own provide a cohesive meaning ). Thus such attribute needs no additional functional support and as such is self-contained. I'm also well-aware that even with self-contained attributes the custom types may prove beneficial ( for example, they give the ability to add new behavior later, when business requirements change ). Thus, my question focuses only on whether custom types for self-contained attributes really enrich Ubiquitous Language UL a) I've read that in most cases, even simple, self-contained attributes should have custom, more descriptive types rather than basic value types ( double, string ... ), because among other things, descriptive types add to the UL, while the use of basic types instead weakens the language. I understand the importance of UL, but how does having a basic type for a self-contained attribute weaken the language, since with self-contained attributes the name of the attribute already adequately describes the concept and thus contributes to the UL vocabulary? For example, the term person_age already adequately explains the concept of quantifying the number of years a person has: class Person { string person_age; } so what could we possibly gain by also introducing the term ThingAge to the UL: class person { ThingAge person_age; } thanks

• Pros and Cons of Facebook's React vs. Web Components (Polymer)

  - by CletusW

  What are the main benefits of Facebook's React over the upcoming Web Components spec and vice versa (or perhaps a more apples-to-apples comparison would be to Google's Polymer library)? According to this JSConf EU talk and the React homepage, the main benefits of React are: Decoupling and increased cohesion using a component model Abstraction, Composition and Expressivity Virtual DOM & Synthetic events (which basically means they completely re-implemented the DOM and its event system) Enables modern HTML5 event stuff on IE 8 Server-side rendering Testability Bindings to SVG, VML, and <canvas> Almost everything mentioned is being integrated into browsers natively through Web Components except this virtual DOM concept (obviously). I can see how the virtual DOM and synthetic events can be beneficial today to support old browsers, but isn't throwing away a huge chunk of native browser code kind of like shooting yourself in the foot in the long term? As far as modern browsers are concerned, isn't that a lot of unnecessary overhead/reinventing of the wheel? Here are some things I think React is missing that Web Components will care of. Correct me if I'm wrong. Native browser support (read "guaranteed to be faster") Write script in a scripting language, write styles in a styling language, write markup in a markup language. Style encapsulation using Shadow DOM React instead has this, which requires writing CSS in JavaScript. Not pretty. Two-way binding
