• Does fast typing influence fast programming? [closed]

  - by Lukasz Lew

  Many young programmers think that their bottleneck is typing speed. After some experience one realizes that it is not the case, you have to think much more than type. At some point my room-mate forced me to turn of the light (he sleeps during the night). I had to learn to touch type and I experienced an actual improvement in programming skill. The most surprising was that the improvement not due to sheer typing speed, but to a change in mindset. I'm less afraid now to try new things and refactor them later if they work well. It's like having a new tool in the bag. Have anyone of you had similar experience? Now I trained a touch typing a little with KTouch. I find auto-generate lessons the best. I can use this program to create new lessons out of text files but it's only verbatim training, not auto-generated based on a language model. Do you know any touch typing program that allows creation of custom, but randomized lessons?

• Structural Typing or Dynamic Typing?

  - by WeNeedAnswers

  I think that the future is for one or both of these type systems. But when would you use Structural over Dynamic and vice vera?

• What is the best free software to learn touch-typing?

  - by gojira

  What is the best free software to learn touch-typing? Features it needs to have: should NOT display the keyboard layout on the screen! should give detailed statistics which actually measure progress (for which key do I have the highest error rate, graphs showing how typing speed improved over time, etc) should enable me to actually learn touch-typing in about one long weekend were I don't do much else than learning to touch-type. it would be very good if it were possible to load a text-file and the program will use words from the text-file for the exercises as well My goals are: at least same typing speed as I have now but which touch-typing, want to be able to look at the screen only when typing P.S.: EDIT: I forgot to mention, I'm using Win 7. And I know what the Dvorak and Colemak keyboard layouts are, but I'm not interested in them. My question was with respect to standard US keyboard layout.

• Optional structural typing possibilty in C++ or anyother language?

  - by ambhai

  In C++ how to tell compiler that Ogre::Vector3 IS_SAME_AS SomeOtherLIB::Vector3 ? I feel that.. in languages like c++ which are not structural typed but there are cases when it makes sense. Normally as game developer when working with 4+ libraries that provide sort or their own Vector3 implementation. The code is littered with ToOgre, ToThis, ToThat conversion function. Thats a lot of Float3 copying around which should not happen on first place. Is in C++ or any other languages where we dont have to convert (copying) from one type to another which is essentially the samething. But any solution in C++ as most of the good gamedevs libs are for c/c++.

• How can I re-enable the typing break in 11.10?

  - by Hamish Downer

  I've just upgraded to beta 2 of Oneiric/11.10 and the typing break has gone. I've gone into the system settings and looked in "Keyboard Layout" and "Keyboard" and can't find anything. Has it just been dropped? Is there some hidden way to re-enable it? Update: Thought I'd write an update based on some stuff that has happened since this question (and the two answers) were written. Workrave has now been re-instated in oneiric-backports and for 12.04 (how to enable backports). It works fine, though if you want to put it in your systray then you need to allow it in there. The easy/lazy command line way to allow workrave into the notification area is to do something like: gsettings set com.canonical.Unity.Panel systray-whitelist "['all']" But read this question if you want a more detailed explanation about what you're doing here. Meanwhile the Gnome typing break has been split out into an app called DrWright, however it has not (at time of writing) been packaged for 11.10 (or later). And as mentioned in the other answer, another option is RSIBreak. It is a KDE app but works fine in Unity.

• What's an example of duck typing in Java?

  - by Cuga

  I just recently heard of duck typing and I read the Wikipedia article about it, but I'm having a hard time translating the examples into Java, which would really help my understanding. Would anyone be able to give a clear example of duck typing in Java and how I might possibly use it?

• Touch Typing Software recommendations

  - by Mike

  Since the keyboard is the interface we use to the computer, I've always thought touch typing should be something I should learn, but I've always been, well, lazy is the word. So, anyone recommend any good touch typing software? It's easy enough to google, but I'ld like to hear recommendations.

• Most Up-To-Date C# Duck-Typing Library

  - by Anton Gogolev

  The title says it all, basically. What is the current state of the art on duck typing for C# below version 4.0? I know about Duck Typing Project, I know that BLTookit has something to that end, but I'd like to know if I'm missing something really wicked apart from DLR languages and C# 4.0. The inevitable:

• Strong Signing, and Updating A Referencing Assembly

  - by Alan

  Hi, I have two, third party assemblies: Foo.dll and ReferencesFoo.dll As noted, ReferencesFoo.dll is an assembly that has a reference to Foo.dll For my application, I need to resign these assemblies. I use ildasm/ilasm in combination along with a signing key to resign them, however, ReferencesFoo.dll still contains (in it's manifest?) the reference to the Foo.dll old public key and public key token. So, how do I sign both dll's with my key, and update the references in ReferencesFoo.dll without getting the source code and recompiling?

• Enforce strong type checking in C (type strictness for typedefs)

  - by quinmars

  Is there a way to enforce explicit cast for typedefs of the same type? I've to deal with utf8 and sometimes I get confused with the indices for the character count and the byte count. So it be nice to have some typedefs: typedef unsigned int char_idx_t; typedef unsigned int byte_idx_t; With the addition that you need an explicit cast between them: char_idx_t a = 0; byte_idx_t b; b = a; // compile warning b = (byte_idx_t) a; // ok I know that such a feature doesn't exist in C, but maybe you know a trick or a compiler extension (preferable gcc) that does that. EDIT: I still don't really like the Hungarian notation in general, I couldn't used it for this problem because of project coding conventions, but I used it now in another similar case, where also the types are the same and the meanings are very similar. And I have to admit: it helps. I never would go and declare every integer with a starting "i", but as in Joel's example for overlapping types, it can be life saving.

• Are you supposed to type '6' with the left hand or the right hand?

  - by Joey Adams

  A few weeks ago, I did a Google Images search for keyboard finger charts to see which fingers I'm supposed to be using to type which keys. According to the charts, '6' is supposed to be typed with the right hand: (as shown on en.wikipedia.org/wiki/Typing) However, today I spotted a split keyboard in a store with the '6' on the left side of the split. Indeed, an image search for split keyboards indicates that this is the norm: (as shown on en.wikipedia.org/wiki/Microsoft_Natural_keyboard) When doing touch typing "correctly", should I go with the finger charts (type 6 with my right hand), or should I go with the split keyboards (type 6 with my left hand)? <troll> Is this just another example of Microsoft not following the standards? </troll>

• what is duck typing?

  - by ashish yadav

  I recently read an article about duck-typing.It said about calling functions of different classes using object of any class. Is it true?And how will the compiler do it on runtime? I apologize if i am not clear.But it really fascinates me , if we could do it dynamically. So if u people got any idea.I am all ears. thank you!! how will the function be accessed by object of any other class. that violates the basic principle of OOP.and that too dynamically during runtime. And is this feature possible in case of OOP languages?

• C++ Typing and OOP child classes

  - by Zack

  I'm a bit confused: If I have a base class A, and a class B which extends A, can a variable of the type A hold a value of the type B and vice versa? If yes, why? Aren't they completely different even if B is derived from A? How about type-safety? If this is possible, what things do I have to mind when taking use of this? How would this work out in terms of performance? Note: Sorry if I asked too many questions, just ignore them and just look out for those "marked" with the list decoration dot :) Also, this is not my homework. I'm a hobby programmer and have skills in scripting languages with OOP, yet I'm relatively new to OOP typing in C++.

• Typing tutor games with good playablity

  - by matt wilkie

  Are there any linux typing tutor games which are enjoyable games in their own right? I'm a computer professional, but have never learned to type properly. I also don't want my kids to pick up my bad habits! The kids are okay with TuxTyping, for a time. Something like Typing of the Dead sounds great, but is Windows only, and as far as I can tell one of a kind. I also don't want the young'uns hooked on first person shooters just yet. So are there any quality typing games for a range of ages?

• Inconsistent mouse cursor status while typing

  - by Jim

  I have noticed that when I type in some programs, Text Editor, Terminal, Bluefish, Gnome Baker, etc. the mouse cursor disappears while I am typing. In other programs like Firefox and LibreOffice, it does not. I am not an application programmer, but I imagined it has to do with their cross-platform nature and the way they are compiled or the toolkits they use. Then I noticed that Gnome-Do behaves the same way, the cursor stays on screen while typing. Why is there inconsistent handling of the mouse cursor, while typing, across different applications? Thank you.

• How to practice typing of programmer keys such as tilde, pipe and programmer quote?

  - by user7893

  It is nice that there are services such as TypeRacer where you can practice casual writing but I want to practice programmer keys, covers more numbers and keys not used by regular typist. There was some tutor with which I practiced some programmer keys and noticed that my speed dropped dramatically from 70-80 wpm to even about 15-30 wpm, it also trains different muscles. So how can I practice just programming keys with programming texts or just random code pieces?

• Implicit typing of arrays that implement interfaces

  - by Sir Psycho

  Hi, I was under the impression that the C# compiler will implicitly type an array based off a type that they can all be implicitly converted to. The compiler generates No best type found for implicitly-typed array public interface ISomething {} public interface ISomething2 {} public interface ISomething3 {} public class Foo : ISomething { } public class Bar : ISomething, ISomething2 { } public class Car : ISomething, ISomething3 { } void Main() { var obj1 = new Foo(); var obj2 = new Bar(); var obj3 = new Car(); var objects= new [] { obj1, obj2, obj3 }; } I know that the way to correct this is to declare the type like: new ISomething [] { obj1, ...} But I'm after an under the covers type help here :-) Thanks

• Interpreter typing in C

  - by typus

  I'm developing an interpreter and I have some questions to it. I recently saw a small C interpreter that used a very simple struct like the below for all its objects/values in the language: struct Object { ubyte type; ubyte value; }; This struct can hold strings, integers, bools and lists (I think) used in the language the interpreter is working with. How can you get this Object struct to hold all these types?

• Borland problem: typing

  - by b3y4z1d

  When I type in Borland C++,it types over the line,not on a new one.That means that every time I press enter,it doesn't give me a fresh,new,empty line in which to type but goes to the one underneath. And there when I try to type I expect the symbols,numbers and letters to move as I add text behind them in the line,but the new symbols keep overwriting the old ones.Sort of deleting them and replacing them with the new characters as I type. Could it be some kinda option I've activated unvoluntarily?

• Generate a Strong Password using Mac OS X Lion’s Built-in Utility

  - by Usman

  You might’ve heard of the LinkedIn and last.fm security breaches that took place recently. Not to mention the thousands of websites that have been hacked till now. Nothing is invulnerable to hacking. And when something like that happens, passwords are leaked. Choosing a good password is essential. A good password generator can give you the best blend of alphanumeric and symbolic characters, making up a strong password. There are a variety of password generators out there, but not many people know that there’s one built right into Mac OS X Lion. Read on to see how you can generate a strong password without any third party application. To do this, open System Preferences. Click “Users & Groups”.

• In what way does non-"full n-key rollover" hinder fast typists?

  - by Michael Kjörling

  Wikipedia claims (although the latter claim does not cite a source) that: High-end keyboards that provide full n-key rollover typically do so via a PS/2 interface as the USB mode most often used by operating systems has a maximum of only six keys plus modifiers that can be pressed at the same time.[4] This hinders fast typists, ... In what way would the system being able to recognize only six non-modifier keys at once hinder a fast typist? I consider myself a relatively fast typist and I usually press one key, plus modifiers, at once; I can't imagine any real-life situation in which the system only recognizing six non-modifier keys being pressed at once has been a limiting factor in my keyboard usage. (Multi-stroke keyboard shortcuts as used by high-end software like Visual Studio, Emacs and the like are a different matter.) Note that I am not really interested in answers centered around multiplayer computer games; I'm looking for answers that give reasons that would be relevant to typists, somehow supporting the statement made on Wikipedia.

• Creating a Strong Bridge to the Post PC World

  - by Webgui

  Moving from location to location requires strong roads.  When crossing a barrier though, like a body of water or valley, we are required to build a strong bridge to get us from point A to point B in a way that is fast, safe, and easy.Yet we are not talking here about driving a car or riding a bus.  As we in the computing world are evidencing the move to the post-PC era, modernizing and migrating legacy applications to harness the power of HTML5 web, cloud and mobile is one of the most difficult challenges enterprises have faced.  Constant technological changes have weakened the business value of legacy systems, which have been developed over the years through huge investments.  There are several risks of course in this move.  Do you choose to simply rewrite code of legacy apps and transform them to HTML5 one by one?  This is quite expensive (according to research firm Gartner, the cost is $6 - $26 per line of code).  Of course, the pace of the rewriting process is very slow – around 170 lines per day for each developer – which slows down business productivity in a world in which no organization can afford to fall behind.  Other questions include whether the new cloud-based apps will have the same functionality as the trusted applications that worked for you for years.  How will the user experience be affected?  And of course, what about data security?  So we are faced with the challenge of building a sturdy bridge to stabilize our move in order to allow us to confidently and easily move our legacy applications into the post-PC era.   We at Gizmox are excited to release the first downloadable Community Technology Preview (CTP) of our Instant CloudMove Transposition Studio.Developers: To download the tool, and try it out for yourself, please visit http://www.visualwebgui.com/download.aspx.The CTP is the first and only tool-based solution allowing any Microsoft Visual Studio developer to extend VB6 and .NET enterprise client/server applications into HTML5 web, cloud and mobile applications, including the ability to upgrade their code and UI while doing so.   It is the only solution to fully replicate enterprise desktop applications behavior in the post-PC era.  With Instant CloudMove, the transposed application is available on any mobile or tablet device, browser and across any client operating system. Moreover, the extended application logic and data remains on the server behind the fire-wall and therefore the application’s front end is secured-by-design.   We would love for you to try out the tool for yourselves and let us know what you think.  How are you finding the move?
