• Pulling in changes from a forked repo without a request on GitHub?

  - by Alec

  I'm new to the social coding community and don't know how to proceed properly in this situation: I've created a GitHub Repository a couple weeks ago. Someone forked the project and has made some small changes that have been on my to-do. I'm thrilled someone forked my project and took the time to add to it. I'd like to pull the changes into my own code, but have a couple of concerns. 1) I don't know how to pull in the changes via git from a forked repo. My understanding is that there is an easy way to merge the changes via a pull request, but it appears as though the forker has to issue that request? 2) Is it acceptable to pull in changes without a pull request? This relates to the first one. I'd put the code aside for a couple of weeks and come back to find that what I was going to work on next was done by someone else, and don't want to just copy their code without giving them credit in some way. Shouldn't there be a to pull the changes in even if they don't explicitly ask you to? What's the etiquette here I may be over thinking this, but thanks for your input in advance. I'm pretty new to the hacker community, but I want to do what I can to contribute!

• Can I build a laptop from scratch?

  - by Ciaran

  I've been looking at this as the same approach as building a desktop computer from scratch but I've never really come across the core things. Can I buy a laptop "case"? Can I buy a motherboard/PSU to fit that case? Can I choose a CPU fan? What are my battery options? Obviously taking into consideration the case. Why isn't this as easy as putting together a desktop computer? Shouldn't there be standards such as ATX? If they exist, what are they?

• Html 5 clock, part ii - CSS marker classes and getElementsByClassName

  - by Norgean

  The clock I made in part i displays the time in "long" - "It's a quarter to ten" (but in Norwegian). To save space, some letters are shared, "sevenineight" is four letters shorter than "seven nine eight". We only want to highlight the "correct" parts of this, for example "sevenineight". When I started programming the clock, each letter had its own unique ID, and my script would "get" each element individually, and highlight / hide each element according to some obscure logic. I quickly realized, despite being in a post surgery haze, …this is a stupid way to do it. And, to paraphrase NPH, if you find yourself doing something stupid, stop, and be awesome instead. We want an easy way to get all the items we want to highlight. Perhaps we can use the new getElementsByClassName function? Try to mark each element with a classname or two. So in "sevenineight": 's' is marked as 'h7', and the first 'n' is marked with both 'h7' and 'h9' (h for hour). <div class='h7 h9'>N</div><div class='h9'>I</div> getElementsByClassName('h9') will return the four letters of "nine". Notice that these classes are not backed by any CSS, they only appear directly in html (and are used in javascript). I have not seen classes used this way elsewhere, and have chosen to call them "marker classes" - similar to marker interfaces - until somebody comes up with a better name.

• Parse text file on click and display

  - by John R

  I am thinking of a methodology for rapid retrieval of code snippets. I imagine an HTML table with a setup like this: one two ... ten one oneTwo() oneTen() two twoOne() twoTen() ... ten tenOne() tenTwo() When a user clicks a function in this HTML table, a snippet of code is shown in another div tag or perhaps a popup window (I'm open to different solutions). I want to maintain only one PHP file named utitlities.php that contains a class called 'util'. This file & class will hold all the functions referenced in the above table (it is also used on various projects and is functional code). A key idea is that I do not want to update the HTML documentation everytime I write/update a new function in utilities.php. I should be able to click a function in the table and have PHP open the utilities file, parse out the apropriate function and display it in an HTML window. Questions: 1) I will be coding this in PHP and JavaScript but am wondering if similar scripts are available (for all or part) so I don't reinvent the wheel. 2) Quick & easy Ajax suggestions appreciated too (probably will use jquery, but am rusty). 3) Methodology for parsing out the functions from the utilities.php file (I'm not to good with regex).

• How to adjust the appearance of the Unity in 12.10?

  - by piedro

  Now I updated to 12.10 and would like to adjust the desktop, well unity, appearance. I know there is the theme setting, but I cannot adjust the symbol theme or windows decoration with the systemsettings. I used to use the tool "unsettings" but it doesn't work with 12.10 anymore. Ubuntu Tweak used to be an option but at this point many features are broken and a lot of settings seem to mess up my system or they don't change anything at all (I understand that there has been a design settings change - gsettings, dconf, something ...) myunity has some options to change stuff but I couldn't find it for 12.10 ... not to forget "gnome-tweak-tool" which seems to work for most settings but not for all, e.g. it doesn't change the mouse cursor and the windows decorations do not show some decorations I'd like to use and I am also afraid of messing things up because it is supposed to be used in gnomeshell ... actually as I found out right now it really messes things up: fonts get inverted, suddenly high contrast accessibility setings are used in some windows, nautilus has white fonts on white background and even the login manager is a mess now ... So: How can I adjust the theme, symbol, decorations, fonts for the normal user and for the desktop and for the applications including the applications started as sudo user? I should mention that I upgraded from 12.04 and that some applications like synaptic completely ignore any settings ... sadly it is a mess, there was a time when gnome theming was really well done and very adjustable, I wonder what happened ... Just now I read that further development of Ubuntu Tweak has been stopped. The developer announced that he won't go any further with the software and the online services ... That is sad and destroys my hope for easy appearance editing just by waiting ... has been such a nice tool for 12.04 ... r.i.p.

• How to keep track of previous scenes and return to them in libgdx

  - by MxyL

  I have three scenes: SceneTitle, SceneMenu, SceneLoad. (The difference between the title scene and the menu scene is that the title scene is what you see when you first turn on the game, and the menu scene is what you can access during the game. During the game, meaning, after you've hit "play!" in the title scene.) I provide the ability to save progress and consequently load a particular game. An issue that I've run into is being able to easily keep track of the previous scene. For example, if you enter the load scene and then decide to change your mind, the game needs to go back to where you were before; this isn't something that can be hardcoded. Now, an easy solution off the top of my head is to simply maintain a scene stack, which basically keeps track of history for me. A simple transaction would be as follows I'm currently in the menu scene, so the top of the stack is SceneMenu I go to the load scene, so the game pushes SceneLoad onto the stack. When I return from the load scene, the game pops SceneLoad off the stack and initializes the scene that's currently at the top, which is SceneMenu I'm coding in Java, so I can't simply pass around Classes as if they were objects, so I've decided implemented as enum for eac scene and put that on the stack and then have my scene managing class go through a list of if conditions to return the appropriate instance of the class. How can I implement my scene stack without having to do too much work maintaining it?

• Performance issues with new dedicated server [closed]

  - by Pierre Espenan

  I have just subscribed to a new dedicated server and am getting worst than expected PHP execution performance. Execution times are twice as high as on my old mutualized server! I'm definitely not an expert at server management, so I'm wondering what I missed. Here are some stuff that can help you understand what's wrong here : My server (in french but easy to understand) : http://www.online.net/fr/serveur-dedie/dedibox-sc phpinfo(); output : http://jsfiddle.net/E8b7W/embedded/result/ PHP bench script (dedicated server) : http://jsfiddle.net/EhXzK/embedded/result/ PHP bench script (old mutualized) : http://jsfiddle.net/ANbWt/embedded/result/ Is it normal to get such poor performances after a kernel update and basics "apt-get install" for apache2 and php ? Thanks !

• emacs keybindings

  - by Max

  I read a lot about vim and emacs and how they make you much more productive, but I didn't know which one to pick. Finally when I decided to teach myself common lisp, the decision was straight forward: everybody says that there's no better editor for common lisp, than emacs + slime. So I started with emacs tutorial and immediately I ran into something that seems very unproductive to me. I'm talking about key bindings for cursor keys: forward/backward: Ctrl+f, Ctrl+b up/down: Ctrl+p, Ctrl+n I find these bindings very strange. I assume that fingers should be on their home rows (am I wrong here?), so to move cursor forward or backward I should use my left index finger and for up and down right pinky and right index fingers. When working with any of Windows IDEs and text editors to navigate text I usually place my right hand in a position so that my thumb is on the right ctrl and my index, ring and middle fingers are on the cursor keys. From this position it is very easy and comfortable to move cursor: I can do one-character moves with my 3 right fingers, or I can press ctrl with my right thumb and do word-moves instead. Also I can press shift with my left pinky and do single-character or word selections. Also it is a very comfortable position to reach PgUp, PgDn, Home, End, Delete and Backspace keys with my right hand. So I have even more navigation and selection possibilities. I understand that the decision not to use cursor keys is to allow one to use emacs to connect to remote terminal sessions, where these keys are not supported, but I still find the choice of cursor keys very unfortunate. Why not to use j, k, i, l instead? This way I could use my right hand without much finger stretching. So how is emacs more productive? What am I doing wrong?

• Lost Windows 7 files

  - by Pader

  My intention was to have a dual boot system with Ubuntu and Windows 7. Obviously I did something wrong because although I had a system menu on booting (is it normal to appear DOS-like?) which gave me an option of booting into windows 7, I was unable to do so. Also, when I booted into Ubuntu, my Windows 7 drive was not available. The Windows 7 drive was an internal 1TB drive partitioned into a 200GB (OS) and a second partition making up the remainder. I was still unable to access this Windows 7 drive even after deleting Ubuntu as I kept getting an 'requires an NTFS drive' error, or something similar. I could not even re-install Windows 7 as the disk was not recognised. I did eventually get the drive back by but I cannot for the life of me remember how. I did try to recover my lost W7 data using Ontrack Easy Recovery (which has always been succesfull in the past for post format recovery) but it would not recognise the 1TB although it was now formatted as NTFS. From other posts on this site, I gather that this is considered a 'Windows 7 Site' problem by Linux users. However, I would dearly love to recover some of my lost Windows 7 files. I had resigned myself to a lot of lost personal data but I happened to notice that a 2TB drive I had connected through a USB docking station had been repartitioned. It must have happened when I installed Ubuntu as I can think of no other explanation. I certainly do not remember consciously requiring Ubuntu to do this. The additional two partitions on the 2TB drive, the original Windows

• Aberdeen 10/25 Webcast: Service Excellence and the Path to Business Transformation

  - by Charles Knapp

  The uncertain economy has had a sustained impact on service organizations and processes. The impact has contributed to new complexities - new customer engagement channels, enhanced user and customer expectations, rapidly evolving technologies, increased competition, and increased compliance and regulatory mandates. Yet many organizations have embraced these challenges by investing in and transforming customer service to evolve, differentiate, and thrive under current constraints. What is their secret? Transforming Support Centers into Profit Centers According to the recent Aberdeen research report, “Service Excellence and the Path to Business Transformation”, service is now viewed as a strategic profit center at nearly 70% of organizations. As customers demand improved service, in terms of speed, efficiency and reliability, an organization's success has become increasingly dependent on optimizing the customer ownership experience. Those service organizations focused on providing easy, consistent, and relevant interactions across the customer lifecycle, including service and support delivery, are experiencing higher levels of customer acquisition and retention and are achieving better revenue and margin growth rates.  Don't miss this opportunity to learn how to transform to provide the next generation of service offerings.

• How to market R at your institute?

  - by ran2

  Okay, I admit there are lots of threads R vs. something. The strengths of R are obvious to most people here. Still though advertising R in an environment that has been preferring various kinds of other software for quite some time is not easy. Moreover, even in the limited time I´ve been dealing with R, it improved so dramatically that I would mention things among its strengths that I would not have listed when I started my personal R-evolution. So, what I am trying to do here is to collect the most recent and striking arguments that can be put in nutshell and be presented easily. What I got on my list so far is: the Springer useR series ggplot2 and its documentation open source CRAN Rapache rcpp rsocket What can you add to this list? SO threads are also very welcome as answers. EDIT: so far, though indeed very helpful, most answers are arguments (pros) why one would want to use R. Do you have some specific hints that I could include in some kind of overview presentation? EDIT2: I wanted to add this link about R's future to the list...

• SQL Server 2012 and SQLMail - will it still work?

  - by Kharlos Dominguez

  We are considering upgrading our SQL Server, which is currently running 2005. We use SQLMail heavily in the organization, both to send e-mails and to import some into a database. I've read on various places that SQLMail was deprecated and superseded by "Database Mail". I'm confused because this MS page: http://msdn.microsoft.com/en-us/library/bb402904.aspx seems to imply that it would still work? I understand the dangers of SQLMail but we do not have the resources to rewrite the scripts right now and would prefer to do it later on. Does SQLMail still work in 2012, and if not, how easy is it to replace with Database Mail, both for reading and sending e-mails?

• Strategy for hosting 700+ domains, each with static HTML site

  - by jonschlinkert

  I have a portfolio of more than 700 domain names, and ideally I'd like to put up a single-page HTML/CSS/JavaScript webpage for each domain. Is there a system/strategy/workflow that will allow me to: Automate the deployment of new websites, quickly and easily without having to manually initiate each new website in an admin panel. For instance, I've seen dropbox-based solutions that claim to make it simple to setup new websites on your dropbox account, but you still have to set each one up in an admin interface first. It would be so much easier to have a folder naming convention that allowed the user to easily clone/copy/duplicate sites inside their Dropbox App folder (https://www.dropbox.com/developers/blog/23) to create new ones. Sounds interesting, however... It's easy to managing CNAMEs on the registrar-side, is there a way to quickly associate CNAMEs with new websites, maybe gh-pages-style (https://help.github.com/articles/setting-up-a-custom-domain-with-pages)? With GitHub's gh-pages, all you have to do is drop a file called CNAME into your repo, with the domain name you want associated with the repo inside the file. gh-pages isn't a good solution for what I'm doing though unfortunately. I'm also a front-end developer, specializing in rapid web development and "front-end build systems", so I building and maintaining static assets for hundreds of sites is no problem. It's the hosting-side that I really struggle with. Any suggestions?

• GeForce and Radeon: what is present condition of opensource and proprietary drivers?

  - by Septagram

  So, it'm about to buy a fresh videocard. Since I do most of my stuff on Linux, I wonder how well will either videocard perform. I recently had a good experience with GeForce 6600 with proprietary drivers and a less than satisfactory experience with Radeon 9000 a while ago. From my experience, proprietary drivers for GeForce used to work very well, while proprietary drivers for Radeon failed miserably. And opensource drivers were sloooow. A few months ago I found out that ATI opened their specifications, and a work on fully featured opensource driver is in progress. I prefer to use free software whenever possible, with the exception of games, so, if that driver is fast enough, feature-rich enough and reliable enough I'd very much like to try it out. I wish I could say that if I can just to basic things, like watch video, heavily use compiz and work with simple applications, this may be enough. I do most of my gaming under Windows anyway. However, there is a good chance I'll go into indie game development in a few months fulltime, so it should also be able to run not-so-very-demanding games (say Nexuiz). But if it isn't, I'd like to know, what to expect from proprietary drivers. Do recent proprietary drivers from NVIDIA and ATI work well? Are ATI drivers just as easy to install on Ubuntu as are NVIDIA drivers?

• Displaying a Grid of Data in ASP.NET MVC

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

• Choosing Truecrypt volume names and keyfile names

  - by Howiecamp

  Any recommendations on what to name Truecrypt volumes (container files) and where to locate them? Certainly a name like "this is a truecrypt volume.tc" isn't a good idea. Any recommended storage locations? Same question for keyfiles that are generated with Truecrypt. Finally, lets say you choose an existing file, ymca.mp3, as your keyfile. Given that that file is innocuous and normal looking, isn't it easy to forget that's your key file so when you get sick of the Village People and delete the song you're hosed?

• Hosting and scaling of a facebook application on cloud?

  - by DhruvPathak

  We would be building a facebook application in django(Python), but still not sure of where to host it economically,and with a good provision to scale in case the app gets viral. Some details about the app: i) Would be HTML based like a website,using django as a framework. ii) 100K is the number of expected pageviews in a day,if the app is viral. iii) The users will not generate any media content,only some database data will be generated by them. It would be great if someone with more experience can guide on following points: A) Hosting on google app engine or Amazon EC2 or some other cloud like RackSpace : Preferable points found in AppEngine were ease of deployment,cost effectiveness and easy scaling. For EC2: Full hold of the virtual machine,Amazon NoSQL and RDMBS database services in case we decide to use them. B) Does backend technology affect monthly cost ? eg. would CPU and memory usage difference of Django over , for example , PHP framework like CodeIgnitor really make remarkable difference in running costs. ( Here is the article that triggered this thought process : http://journal.dedasys.com/2010/01/12/rough-estimates-of-the-dollar-cost-of-scaling-web-platforms-part-i#comments) C) Does something like Heroku , which provides additional services over Amazon EC2, prove to be better than raw cloud management ? It is not that we are trying for premature scaling, we just want to have a good start so that we are ready to handle unpredicted growth and scale.

• Downloaded chm is blocked, is there a solution?

  - by David Rutten

  CHM files that are downloaded are often tagged as potentially malicious by Windows, which effectively blocks all the html pages inside of it. There's an easy fix (just unblock the file after you download it), but I was wondering if there's a better way to provide unblocked chm files. What if I were to download the chm file (as a byte stream) from our server inside the application, then write all the data to a file on the disk. Would it still be blocked? Is there another/better way still? Edit: Yes, downloading the file using a System.Net.WebClient does solve the problem. But, is there still a better way?

• easiest way to (download and) convert HTML-structures into EPUB?

  - by gojira

  How would one (download and) convert HTML-structures into EPUB (or any other format suitable for the Sony PRS-505 reader)? My question is not how to convert a single HTML file into an EPUB file, as this is easy; what I mean is, I have some books I want to read on my Sony PRS-505 and these books are most often online in HTML format but withmany interlinked pages and there is one page with the list of contents, like this example http://www.edge.org/documents/ThirdCulture/d-Contents.html ... or sometimes it's a little bit more complicated as the list of contents only lists the chapters, and inside the chapters there are links to sub-chapters, like in this example: http:SLASHSLASHwww.hyw.com/Books/WargamesHandbook/Contents.htm (I can only post 1 hyperlink now b/c of user restriction, so this is why there is SLASHSLASH instead of //) I want to convert these examples and several others, with correct chapters, images and some acceptable formatting etc, so basically I want to make a proper ebook out of the HTML-tree. What is the easiest way?

• How to Effectively Create Bullet Patterns

  - by SoulBeaver

  I'm currently creating a top-down shooter like Touhou. The most important factor of the game is that there are many diverse patterns and ways at which bullets are generated and shot at the player, see this video: http://www.youtube.com/watch?v=4Nb5Ohbt1Sg#start=0:60;end=9:53; At the moment, I'm using a class "Pattern" which has a series of steps on moving and shooting. However, I feel this method is quite laborous as I have to create a new Pattern for each attack and perhaps new Bullet classes that will implement a certain behavior. This question received a comment suggesting I should look into BulletML for easy creation and storage of bullets with a specific pattern. It looks decent, but it led me to wonder, what other solutions do you have that I should take into consideration? Update My current design is as follows: An example of an implemented pattern: My GigasPattern first executes a teleport which moves Alice to a certain point (X, Y) on the screen. After this is completed, the pattern starts using the Mover to move the sprite around (whereas teleporting has separate effects and animation). These are of no concern, really, as they are quite simple. The Shooter also creates various Attacks, which are classes again that the Shooter can use to create various patterns of bullets, much like the one in the question I posted. Once the Mover has reached it's destination, both it and the shooter stop and return to an inactive state. The pattern completes, is removed by the AI and a new one gets chosen.

• Release notes for 9/25/2012

  Below are the release notes from today's deployment. 1. With today’s deployment we’ve made some significant changes to the source code experience. First of all, you’ll noticed that we moved the Source Code tab closer to the project home tab.   We believe that this will help make source code more discoverable and emphasizes our focus on developer collaboration. The next thing you’ll notice is that when you click on the Source Code tab, you will immediately be browsing code. We want to get you to the project source code in a minimum number of clicks, and this change helps get you there. The changeset history is still there, which brings us to the next change… We implemented an action bar in the source code section, which will make certain actions more discoverable, including forking, cloning, and downloading source code The popups in the action bar will help you perform the tasks you need to do when contributing to projects, as well as managing your own projects. Take a look at how easy it is to find the clone/connection URL now! 2. The second exciting thing we turned on this week is the ability to enable Windows Azure Web Sites to build and deploy your project source code (for Git source code projects). You can read more about how to do this in Mark's post here. 3. We also made some improvements in other areas this week: Made some improvements to screen reader accessibility Fixed some minor UI issues in the browse source code page We'd love to have your feedback on the new changes to the source code tab. Please let us know what you think on our suggestions page, send us a message on Twitter @codeplex, or you can reach Mark Groves directly @mgroves84

• Leveraging NuGet as a central repository for PowerShell modules

  - by cibrax

  We have been working a lot lately with PowerShell as part of our star product at Tellago Studios, “Moesion”. One of the main features we provide in Moesion is the ability to execute PowerShell commands remotely in a given server using a web mobile interface (You can read more in my previous post about Moesion). One of the things we realized in all this time is that PowerShell lacks of a central repository where IT guys or we, the developers, can easily grab and reuse commands.  All the commands or modules are basically spread across multiple places or websites, like personal blogs, TechNet or CodePlex projects to name a few making the search of them very hard. You are usually limited to use your favorite search engine and copy what you find. In addition, there is not an easy way to reuse, extend or version these commands, which also limits any contribution that you could make to the community.  My friend Jose wrote a great post the other day about the importance of reusing PowerShell modules, and what is the mechanism to reuse them. Jose, however, based his post in a custom implementation using a GIT repository for storing the modules. We have NuGet in the .NET platform for sharing and reusing existing libraries or code, so why can’t just leverage it for reusing PowerShell modules as well ?. Some teams in Microsoft are using NuGet for distributing libraries and binaries so it would be a great thing for all of us if they also distribute the scripting interfaces in PowerShell using NuGet. This applies to the .NET OS community as well. In fact, it looks like Andrew Nurse had the same idea and implemented a project for this in BitBucket, PsGet.

• Zensyslog Clear Events

  - by Stefan Mai

  I've hooked up Zenoss' Zensyslog so that messages from a distributed list of client machines are all conglomerated into events on the Zenoss server. This is all fantastic, and I can bump messages by simply using the logger command: logger -t webserver_is_down "The web server is down" What I'd like to be able to do is also post an event that clears for when the webserver comes up. logger -t webserver_is_up "The web server is up" I've tried to set this up with Event classes but with no dice. Is there a Syslog level that correlates with Zenoss' clear/0 level? Is there another easy way to do this? Thanks for any help you can give!

• How to remove the last character from Stringbuilder

  - by hmloo

  We usually use StringBuilder to append string in loops and make a string of each data separated by a delimiter. but you always end up with an extra delimiter at the end. This code sample shows how to remove the last delimiter from a StringBuilder. using System; using System.Collections.Generic; using System.Text; using System.Linq; class Program { static void Main() { var list =Enumerable.Range(0, 10).ToArray(); StringBuilder sb = new StringBuilder(); foreach(var item in list) { sb.Append(item).Append(","); } sb.Length--;//Just reduce the length of StringBuilder, it's so easy Console.WriteLine(sb); } } //Output : 0,1,2,3,4,5,6,7,8,9 Alternatively,  we can use string.Join for the same results, please refer to blow code sample. using System; using System.Collections.Generic; using System.Text; using System.Linq; class Program { static void Main() { var list = Enumerable.Range(0, 10).Select(n => n.ToString()).ToArray(); string str = string.Join(",", list); Console.WriteLine(str); } }

• Visually and audibly unambiguous subset of the Latin alphabet?

  - by elliot42

  Imagine you give someone a card with the code "5SBDO0" on it. In some fonts, the letter "S" is difficult to visually distinguish from the number five, (as with number zero and letter "O"). Reading the code out loud, it might be difficult to distinguish "B" from "D", necessitating saying "B as in boy," "D as in dog," or using a "phonetic alphabet" instead. What's the biggest subset of letters and numbers that will, in most cases, both look unambiguous visually and sound unambiguous when read aloud? Background: We want to generate a short string that can encode as many values as possible while still being easy to communicate. Imagine you have a 6-character string, "123456". In base 10 this can encode 10^6 values. In hex "1B23DF" you can encode 16^6 values in the same number of characters, but this can sound ambiguous when read aloud. ("B" vs. "D") Likewise for any string of N characters, you get (size of alphabet)^N values. The string is limited to a length of about six characters, due to wanting to fit easily within the capacity of human working memory capacity. Thus to find the max number of values we can encode, we need to find that largest unambiguous set of letters/numbers. There's no reason we can't consider the letters G-Z, and some common punctuation, but I don't want to have to go manually pairwise compare "does G sound like A?", "does G sound like B?", "does G sound like C" myself. As we know this would be O(n^2) linguistic work to do =)...
