• Laser range finder, what language to use? Beginner advice

  - by DrOnline

  I hope this is the right place. I am a programming beginner, and I want to make a laser range finder, and I need advice about how to proceed etc. In a few weeks I will get a lot of dirt cheap 3-5V lasers and some cheap usb webcams. I will point the laser and webcam in parallel, and somehow use trigonometry and programming to determined distance. I have seen online that others made done it this way, I have purposefully not looked at the details too much because I want to develop it on my own, and learn, but I know the general outline. I have a general idea of how to proceed. The program loads in a picture from the webcam, and I dunno how images work really, but I imagine there is a format that is basically an array of RGB values.. is this right? I will load in the red values, and find the most red one. I know the height difference between the laser and the cam. I know the center dot in the image, I know the redmost dot. I'm sure there's some way to figure out some range there. TO THE POINT: 1) Is my reasoning sound thus far, especially in terms of image analysis? I don't need complete solutions, just general points 2) What I need to figure out, is what platform to use. I have an arduino... apparently, I've read it's too weak to process images. Read that online. I know some C I know some Python I have Matlab. Which is the best option? I do not need high sampling rates, I have not decided on whether it should be automated or whether I should make a GUI with a button to press for samples. I will keep it simple and expand I think. I also do not need it to be super accurate, I'm just having fun here. Advice!

• How does Game Salad compare with Cocos2D in terms of 2D game development?

  - by jih

  I want to make some 2d games for iOS. I first come across cocos2d and kobold but then wanted something more graphical for rapid prototyping. I then found Game Maker which doesn't support iOS but is fairly easy to learn and then found Game Salad which supports iOS as well as other platforms. I know this question has been ask before but I want to know in terms of the types of games I want to develop what an learning investment path would be best. The types of games genre I am interest are: Side scrollers Simple games like diamond dash or ninja fruits, shanghai, etc Old fashioned zelda or dragonquest type (nintendo fan here:-) 2d adventure RPG games (real time or turn based) Mystery turn based games like carmen sandiego, wizardry, myst etc. So now the question becomes for me becomes which game development environment should I invest my time in learning. Game Salad or cocos2d? To make that decision I was wondering if experienced game programmers and help with some pointers: It would seem game salad would be great for quickies being graphical but in terms of 2d platform games etc would there be speed/performance/feature penalties? Are there certain 2d games genre of the 4 above that Game salad is better at while certain type cocos2d would be better at?

• Installing software from source

  - by Learning

  I'm trying to understand the rational behind installing from software from source in Ubuntu 12.04. Obviously, I know I can download what I need from repos, but I want to develop a deeper understanding of Linux. As a Windows users, when I download a program I double click it, and it installs into the program files directory unless I specify otherwise. When I want to uninstall it, Windows has a tools that does that for me. When I install a program in Linux, where does it install to? How do I uninstall it afterwards? Are there residual files left over? How would I tell if it's been fully removed? For instance, I'm going to install LMMS (Linux Multimedia Studio) from source. I download and decompress the tar ball, and have a folder name lmms_XXX.tar (whatever). The folder is now on my desktop with an install file. If I run the install file from that location, does it install into that folder? If so, can I move that folder to where ever I want? I want thinking about putting it in /opt/lmms

• Grub2 cannot detect Windows 8

  - by MetaChrome

  At installation it did not detect Windows. I mounted the Windows partition and have run os-prober with no results returning. I am able to boot Windows or Ubuntu by specifying the partition in UEFI boot order. The bios does not appear to allow booting with legacy. SecureBoot is on. This is with Ubuntu 12.04 LTS on a Inspiron 15. Here is the gdisk: 1 2048 1026047 500.0 MiB EF00 EFI system partition 2 1026048 1107967 40.0 MiB FFFF Basic data partition 3 1107968 1370111 128.0 MiB 0C01 Microsoft reserved part 4 1370112 2394111 500.0 MiB 2700 Basic data partition 5 2394112 544743423 258.6 GiB 0700 Basic data partition 6 606183424 625140399 9.0 GiB 2700 Microsoft recovery part 7 544743424 545230847 238.0 MiB 0700 (/boot) 8 545230848 556949503 5.6 GiB 8200 (swap) 9 556949504 606181375 23.5 GiB 0700 (/) When installing ubuntu, I believe I specified that the bootloader be installed on /dev/sda. I added the following to /etc/grub.d/40_custom but booting ubuntu did not offer a grub menu: menuentry "Windows 8" { set root = "(hd0,4)" chainloader +1 } When booting I think I see "EFI Disk error" flash very quickly before Ubuntu starts booting.

• Game programming : C# or C++?

  - by Chronix

  Ok so the faq says : "What language should I learn next? (Unless you have a specific requirement and don't know which language meets that requirement.)" so I guess this is not against the rules of questions. So, I've decided what I really want is to do Game Programming. So the question is, as a 18 years old who wants to learn self taught programming, what is the most suited programming language between C# and C++? ( I should state that I don't care about unix because I believe windows will be still the most used os ) I know the basics of C++, but none about C#. I know that C++ has more tutorials guides, dlls and stuff like that, while C# doesn't, but it's far easier to learn and to use for a single person to develop a program, but I've read even if the program is obfuscated it's easy to get the source of it. Well, I kinda want to focus on basic a lot first, I must say that I have a preference for C++ just because it feels more suitable to me, but I must consider that I work alone.. So even if I like it, it may not be the best thing to do. I am really not sure of which one to go for, i've read a lot of threads on various websites and it looks like C# is becoming more popular than C++. But yeah, that said, I also specified I want to do Game Programming. So I need to know some better points than just "C# is easier because of .net memory handling while C++ isnt" because I couldn't just find it. I hope the thread won't be closed because I've read the faq and I have a specific requirement. Thank you, and if you need more details you're free to ask me, but I think just by saying game programming and that I'd work alone should be enough!

• Simple (and fast) dices physics

  - by Markus von Broady

  I'm programming a throw of 5 dices in Actionscript 3 + AwayPhysics (BulletPhysics port). I had a lot of fun tweaking frictions, masses etc. and in the end I found best results with more physics ticks per frame. Currently I use 10 ticks per frame (1/60 s) and it's OK, though I see a difference in plus for 20 ticks. Even though it's only 5 cubes (dices) in a box (or a floor with 3 walls really) I can't simulate 20 ticks in a frame and keep FPS at 60 on a medium-aged PC. That's why I decided to precompute frames for animation, finishing it in around 1700 ticks in 2 seconds. The flash player is freezed for these 2 seconds, and I'm afraid that this result will be more of a 5 seconds or even more, if I'll simulate multi-threading and compute frames in background of some other heavy processes and CPU drawing (dices is only a part of this game). Because I want both players to see dices roll in same way, I can't compute physics when having free resources, and build a buffer for at least one throw of each type (where type is number of dices thrown). I'm afraid players will see a "preparing dices........." message too often and for too long. I think the only solution to this problem is replacing PhysicsEngine with something simpler, or creating own physicsEngine. Do You have any formulas for cube-cube and cube-wall collision detection, and for calculating how their angular and linear velocities should change after a collision occurs?

• Type of AI to tackle this problem?

  - by user1154277

  I posted this on stackoverflow but want to get your recommendations as well as a user on overflow recommended I post it here. I'm going to say from the beginning that I am not a programmer, I have a cursory knowledge of different types of AI and am just a businessman building a web app. Anyways, the web app I am investing in to develop is for a hobby of mine. There are many part manufacturers, product manufacturers, upgrade and addon manufacturers etc. for hardware/products in this hobby's industry. Currently, I am in the process of building a crowd sourced platform for people who are knowledgeable to go in and mark up compatibility between those parts as its not always clear cut if they are for example: Manufacturer A makes a "A" class product, and manufacturer B makes upgrade/part that generally goes with class "A" products, but is for one reason or another not compatible with Manufacturer A's particular "A" class product. However, a good chunk (60%-70%) of the products/parts in the database can have their compatibility inferenced by their properties, For example: Part 1 is type "A" with "X" mm receiver and part 2 is also Type "A" with "X" mm interface and thus the two parts are compatible.. or Part 1 is a 8mm gear, thus all bushings of 8mm from any manufacturer is compatible with part 1. Further more, all gears can only have compatibility relationships in the database with bushing and gear boxes, but there can be no meaningful compatibility between a gear and a rail, or receiver since those parts don't interface. Now what I want is an AI to be able to learn from the decisions of the crowdsourced platform community and be able to inference compatibility for new parts/products based on their tagged attributes, what type of part they are etc. What would be the best form of AI to tackle this? I was thinking a Expert System, but explicitly engineering all of the knowledge rules would be daunting because of the complex relations between literally tens of thousands of parts, hundreds of part types and many manufacturers. Would a ANN (neural network) be ideal to learn from the many inputs/decisions of the crowdsource platform users? Any help/input is much appreciated.

• Why choose an established CMS as opposed to building one from scratch?

  - by SkonJeet

  A lot of my research over the next few weeks will be into different CMS's. I've already had a brief look at episerver and umbraco. While reading into these systems I can't help but think that providing content management features are achievable without learning the details and structure of many of these (rather large) CMS platforms. I have, in the past, been given projects whereby my role as a developer must be kept separate to that of an editor (makes sense). i.e. It was my task to develop the design and functionality of the site and my clients' job to update the content. I've achieved this by also implementing a sort of 'portal' on which there were a couple of pages that would accept text input and picture uploads etc. (basically, whatever content they wanted), record this new content to the database and then by design the code-behind would read all this from the database into relevant controls (repeaters for example). For me, this has been an effective enough way of my clients managing the content to deploy with my solutions. I know that I am wrong - and that CMS's are preferable to those that are built from the ground up - but other than the matter of cost, why?

• Lubuntu 12.10: Icon Display Problems

  - by SlcBullseye

  First off, I would like to let you know that I am new to Linux. I finally decided to give it a try and my first project was installing Lubuntu on an old PC and using it for a media server for my PS3. So, one thing that I noticed right away is that my icons for applications, files, folders, etc...are not visible. If I move my mouse over the name of the application or file (It only works if I move the mouse up from the bottom of the name) then the icon will appear, but if I move my mouse back over any other place on the file the icon will disappear again. Also, if I open a folder sometimes an icon or two will be displayed but the rest won't, and like I said before if I move my mouse over the top of the application or file the icon will disappear. Is there any way to fix this? Is this normal? Or could it be a problem with my hardware? I never had this issue when I was running the last OS (Windows XP). Any help would be greatly appreciated. Remember, I am new to Linux so a thorough explanation would be helpful. Also, if there are any tips, tricks, references, or recommendations any of you have to help me jump in and become more familiar with using Linux that would be great! I'm very interested in taking advantage of the power Linux has. Currently I am studying computer programming so maybe one day I will be able to develop my own Linux distribution.

• Can you recommend a game server for a facebook board game?

  - by Yekmer Simsek

  I am seeking a game server that will scale well. All commercial and/or free software alternatives are welcome. Game will be a boardgame that is similar to poker. Some technical details are listed below. There will be a table which consists of 4 people, to send them message I need a channel manager. A table will be ready to play for at least 5 minutes. There should be a reliable channel manager. People will wait for some time(i.e.) and if they are not playing they will be kicked by server, so there will be a reliable timed task queue to execute some tasks. It should be quick enough to response and show the changes to all 4 people on that table simultaneously.To achive this server should have a powerfull I/O library. I think to use inmemory to have quick response times, but it comes with scalability problems. And some variables should be thread safe so a variable should be thread safe between multiple nodes. Flash(AS3) and Unity (.Net 2.0 C# mono) client API's should be available for socket connection. PS: I am using Reddwarf server, it lacks of documentation and multiple node.

• WINAPI window management question

  - by gekod

  I'm learning to develop windows applications using WINAPI and plain C. Now I got a bit confused with all those handles and would like to ask if you guys could teach me some good practices to structure and handle controls and windows. Here's where I get confused: Using the IDs declared in the resources for each object, we can get their handles using GetDlgItem(). Now what if we don't know their parent, which is needed by this function. One example: We have the main window created at launch. Then we register two new window classes and create a window for each new class and we create a message function for each too. Now if inside one of the children windows I create a button and inside the other child window I create a text label. Now when we click the button inside of child window A the label in child window B shall be modified to whatever. The WM_COMMAND for the button is interpreted inside the message loop for child window A. Now what would be the best and more elegant way to access the text label inside the child window B? I am in the process of learning the WINAPI and just want to learn it right from the start instead of producing Hacked code that someday becomes unreadable and to later have to adapt to a new way of programing.

• How can I make sure my evening project code is mine?

  - by Sebastian

  I'm a physicist with a CS degree and just started my PhD at a tech company (wanted to do applied research). It deals with large scale finite element simulations. After reviewing their current approach, I think that a radically different method has to be applied (they are using a commercial tool which is very limited). I'd rather base my research on an open source finite element solver and write a program which makes use of it. I'd like to develop this idea in the evenings, because that's the time that best suits me for programming (during the day I prefer reading and maths) and use it at a late stage of my PhD. I'd like to have the option to release my program as open source on my website as a reference, for future personal or even commercial (e.g. consulting) use. How can I make sure that my company doesn't claim the code ownership? I don't really I thought that a version control system could help (check out only in the evening). This would document that I programmed not during regular office hours (documented elsewhere). But these data can be easily manufactured. Any other ideas? I want to stress that I'm not interested in selling software. Jurisdiction is EU, if that matters. Thank you.

• Game with changing logic

  - by rsprat

  I'm planing to develop a puzzle like mobile game (android/ios) with a different logic for each puzzle. Say, for example one puzzle could be a Rubik's cube and another one a ball maze. Many more new puzzles will appear during the life of the game, and I want the users to be able to play those new puzzles. The standard way for managing this would be through application updates. Each time a new puzzle or bunch of puzzles appear, create a new update for the app that the user can download. However, I would like to do it in a more transparent way. When a new puzzle appears, the basic info of the puzzle would be displayed in the app menu, and the user would be able to play it by just clicking it. What comes to my mind is that the app would automatically download a .dll or .jar and inject it in the application at runtime. Is that even possible? Are there any restrictions from the OS? Is there a better way for solving it? Thanks alot

• How to handle the fear of future licensing issues of third-party products in software development?

  - by Ian Pugsley

  The company I work for recently purchased some third party libraries from a very well-known, established vendor. There is some fear among management that the possibility exists that our license to use the software could be revoked somehow. The example I'm hearing is of something like a patent issue; i.e. the company we purchased the libraries from could be sued and legally lose the ability to distribute and provide the libraries. The big fear is that we get some sort of notice that we have to cease usage of the libraries entirely, and have some small time period to do so. As a result of this fear, our ability to use these libraries (which the company has spent money on...) is being limited, at the cost of many hours worth of development time. Specifically, we're having to develop lots of the features that the library already incorporates. Should we be limiting ourselves in this way? Is it possible for the perpetual license granted to us by the third party to be revoked in the case of something like a patent issue, and are there any examples of something like this happening? Most importantly, if this is something to legitimately be concerned about, how do people ever go about taking advantage third-party software while preparing for the possibility of losing that capability entirely? P.S. - I understand that this will venture into legal knowledge, and that none of the answers provided can be construed as legal advice in any fashion.

• ADF Hands on Training &ndash; Prerequisites for 22nd March 2011

  - by Grant Ronald

  For those of you coming to the ADF Hands on training on the 22nd March in London, there was a link to the prerequisites.  Unfortunately, in a reshuffle of content on OTN, this page was removed.  So, over the next day or so I’m hoping to the pull together the relevant information into this blog post.  So keep checking back! Firstly, you need to being your laptop with you to do the hands on exercises.  No laptop, no hands on. Recommended 2GB RAM running Microsoft Windows XP SP2, 2003 Server SP2, Vista (32 bit only), Windows 7 or Linux or Mac 2GHz Processor (less will be acceptable but slower) Mozilla Firefox 2.0 or higher, Internet Explorer 7 or higher, Safari 3.0 and higher, Google Chrome 1.0 or higher Winzip or other extracting software Adobe Acrobat reader Flash (if you want to see dynamic graphs in your application) As for software, you will need have installed JDeveloper 11g.  The hands on instructions are based on 11.1.1.2 (or is it 11.1.1.3)! anyway, either of those or 11.1.1.4 would be required. You also need an Oracle database on your machine and access to the HR schema (which should be unlocked).  Don’t expect to have access to a network and VPN to a database. A simple test, unplug your laptop from your corporate network, run up JDev  and select File –> New –> Database connection and make sure you can connect to HR database and see the Emp/Dept etc tables.  If you can do that, you should be good to go. I would strongly recommend ensuring you have this in place before you arrive on Tuesday. Look forward to seeing you there.

• Will buy simple Cocos2D bubbles iPad game for private use (source)

  - by boliva

  Hi, First of all, sorry if this is the wrong place for posting this kind of request. IDK if is there already a marketplace on the stack community. I'm a fairly experienced iPhone/iPad developer with several Apps already published. I have a deep understanding of Objective-C and the Cocoa framework, as well as with the iPhone development tools. However, I have never used Cocos2d (or any other gaming engine for that matter) as I've mostly specialized in utilities/productivity Apps. I am in the urgent need of developing a really simple iPad game (for which I will provide all of the media assets - graphics and sounds) that needs to be deployed in about a week from now. Basically the game should allow the user to pop bubbles of different size and speed as they move from the bottom to the top of the screen. While I could take the time to read the documentation and start working on this game myself, I'm currently with a couple of other projects that I need to finish soon, so I would like to ask for the help of some other more experienced Cocos2D developer which could develop this game on its basic form for me. If you think you can help, please send me your quote, timing and, if possible, samples of previous work done with Cocos2D that would be similar to what I need. I can provide more detail upon request. Best and thank you all.

• Building MySQL with boost on windows

  - by user13177919

  As you've probably heard already MySQL needs boost to build. However, in the good ol' MySQL tradition, the above link does give you only the instructions on how to build it on linux. And completely ignores the fact that there're other OSes too that people develop on. To fill in that gap, I've compiled a small step by step guide on how to do it on windows. Note that I always, as a principle, build out-of-source. The typical setup I have is : bzr clone lp:~mysql/mysql-server/5.7 mysql-trunkcd mysql-trunkmkdir bldcd bldcmake -DWITH_DEBUG=1 -DMYSQL_PROJECT_NAME=mysql-trunk ..devenv /build debug mysql-trunk.sln This has been tested to work on a 32 bit compile using VS2013 on a Windows7 64 bit build. Note that you'll need other things too (bison, eventually openssl etc) that I will assume you already have set up. Steps: Download Boost 1.55.0. It's the *only* version that is known to work currently. Extract boost_1_55_0/ from the zip to c:\boost\boost_1_55_0 Go to Control Panel/System/Environment variables and set WITH_BOOST=C:\boost\boost_1_55_0 in User variables. Make sure you restart your open command line terminal windows after this !  If you're upgrading from non-boost build, remove your bld/ directory and create a new one. run cmake as you'd typically do. You should get: -- Local boost dir C:/boost/boost_1_55_0 -- Local boost zip LOCAL_BOOST_ZIP-NOTFOUND -- BOOST_VERSION_NUMBER is #define BOOST_VERSION 105500 -- BOOST_INCLUDE_DIR C:/boost/boost_1_55_0 Build as normal (devenv /build debug ...). It should work.

• Website only displays correctly in IE using compatibility mode?

  - by user21318

  As the resident "IT Whiz" at work (ie: I know how to use a computer) I've been asked to develop a website for our small business. I've altered a wordpress theme for the time being and the company is very happy with the results. The only problem I am having with it at the moment is that for some reason the website does not display correctly and Internet Explorer unless I run it in Compatibility Mode. The main problem that I have is that my menu "slider" (it rotates pictures with links to articles etc) does not display at all, neither does the top menu they are just blink text based links. Even with Compatibility Mode enabled the slider and menus come back but the page is not centered unlike on both Firefox and Chrome. My googling has suggested the most common cause of this is old code but I'm not sure where to be looking. Is it likely in the css file or the actual php? Also any ideas on how to trouble shoot the cause of this? As in is there some dev tools or debugger I can use that would highlight "broken" code for me?

• Making HTML5 videos stored on AWS S3 **difficult** to download (because I cant make it impossible)

  - by Jimmery

  I am building a website that hosts video's stored on AWS's S3 service. The videos are played thru a HTML5 player we have built. Ive just been asked to make sure "nobody can steal our video's". Now I know that if you really don't want something stolen, don't put it up on the internet. However I just need to secure these videos as good as possible, the videos need to at the very least resist someone going thru the source code and trying to download them manually. One option available to me is to completely rebuild the video player in flash. This is not ideal, for several reasons, notably because I would also then have to build an App for mobile devices to be able to view this site. So I am looking for other options. I have heard about using a token to make the file available only during certain times. I have heard of using a separate file to serve the videos that sits between the HTML5 page and the video file. I am also having a look at IAM, the Secure AWS Access Control, in the hopes AWS can solve this problem for me. Can anyone here recommend any of these options? Or perhaps suggest other options available to me? Any help would be greatly appreciated.

• Trouble installing from disk

  - by SuperNatural

  I'm writing this in desperation, Windows is slowly killing me and i need to change my home pc os to Ubuntu 11.04 as soon as possible. I created a USB flash drive to install ubuntu, twice, and both times they failed to begin install on restart of my pc. i read on another forum that you might have to change some boot sequence in BIOS but when pressing F2 to enter it didnt work. After a lot of cursing, I made myself an UBUNTU install cd and booted. To my excitement, it now displayed... try ubuntu and install ubuntu. i clicked install ubuntu which lead me to the preparing to install ubuntu display, i checked download updates while installing and clicked forward. The very next display is ' allocate drive space ' i assume there are meant to be options of drives provided but mine is just a blank box and underneath all the options to create a new partition table, add, change, delete and revert are all greyed out. There is a drop down menu labelled 'device for boot loader installlation' but the only option is /dev/sda. when i click install, a no root file system error comes up telling me to please correct from the partitioning menu. I am extremely frustrated. please!! can anyone help me...

• Battery life low on notebook using ubuntu 11.10 vs. windows 7

  - by les

  Im using a brand new Dell XPS notebook (bought mar 2012) which has 4.5 hrs battery life using a 6 cell battery-when i use windows 7. The machine uses an Intel core 17 2670qm processor, and a 64 bit operating system. I downloaded Ubuntu 11.10 and installed it on a USB drive, which is how i use it. I still have Windows 7 on the machine. When the machine is booting up I hit F12, and run Ubuntu from the flash drive instead of the machine booting Windows, as it normally would. On the Ubuntu menu, on the top right area, there is a battery menu, which shows how long to charge battery, or how much life left etc..with a fully charged battery the most Ubuntu will give me is 1.5 hrs. I've adjusted all power setting etc by clicking on the battery meter where i can make these adjustments, and have even turned down the brightness on the monitor. I've read through these questions here, and a user wrote to install Ubuntu 12(?)(the alpha version) when it's out this month(april), and this has better power management. Other forums (Ubuntu wiki) state that windows 7 controls power management effectively because it's configured to work with the hardware. I'd like to install Ubuntu and wipe windows but can't because of this issue. I need my notebook to go hours, not an hour and a bit. Can anybody recommend possibly a good software to use, that will work with the machines bios under Ubuntu? Another thought of mine, is- since I didn't yet wipe windows off my hard disk, is windows still possibly controlling the power mgmt aspect on the machine? I've thought of calling tech support at Dell and asking for help there, maybe Dell has something (a tweak?), I can download that'll work under Ubuntu. Looking forward to any help/suggestions i can get here, i'm really stuck on this..

• Data recovery on a Samsung SV1203N HDD

  - by Jim Conace

  Let me start by saying that I am a beginner in Ubuntu, but pretty knowledgeable with Windows. I am having a strange problem trying to recover data from a Samsung SV1203N HDD (120 GiB). I have tried numerous things in both Windows 7 and Ubuntu 12.04 LTS (on a flash drive, an external HDD and a Live CD). This drive has some very important data on it and I am praying some of you Ubuntu geeks can help me get it back. Here's my problem. The HDD is clicking while I am booting, but it stops when I get into Ubuntu or Windows. It refuses to be detected in the bios, so I cant perform any tests on it. I have tried numerous things in both Windows (repair CD, Jumpers, etc.) and Ubuntu (Boot-Fix, GParted, Testdisk, Photorec, forcing a mount, etc.). But it all seems to lead me back to the fact that the drive is not being recognized in the BIOS. I've even tried chilling the drive in the fridge, which worked well for another drive I work on, and I recovered all of the data in Ubuntu flawlessly. I am assuming that since the drive stops clicking when I get into the OS' that there is hope for recovery. I am going to try an IDE/SATA to USB cable, and replacing the Logic Board, but I want to exhaust all other possibilities before I do that. Any help would be greatly appreciated Bye

• How can I convince my boss that ANSI C is inadequate for our new project?

  - by justifiably cowardly

  A few months ago, we started developing an app to control an in-house developed test equipment and record a set of measurements. It should have a simple UI, and would likely require threads due to the continuous recording that must take place. This application will be used for a few years, and shall be maintained by a number of computer science students during this period. Our boss graduated some 30 years ago (not to be taken as an offense; I have more than half that time on my back too) and has mandated that we develop this application in ANSI C. The rationale is that he is the only one that will be around the entire time, and therefore he must be able to understand what we are doing. He also ruled that we should use no abstract data types; he even gave us a list with the name of the global variables (sigh) he wants us to use. I actually tried that approach for a while, but it was really slowing me down to make sure that all pointer operations were safe and all strings had the correct size. Additionally, the number of lines of code that actually related to the problem in hand was a only small fraction of our code base. After a few days, I scrapped the entire thing and started anew using C#. Our boss has already seen the program running and he likes the way it works, but he doesn't know that it's written in another language. Next week the two of us will meet to go over the source code, so that he "will know how to maintain it". I am sort of scared, and I would like to hear from you guys what arguments I could use to support my decision. Cowardly yours,

• Reliance on the compiler

  - by koan

  I've been programming in C and C++ for some time, although I would say I'm far from being expert. For some time I've been using various strategies to develop my code such as unit tests, test driven design, code reviews and so on. When I wrote my first programs in BASIC I typed in long listings before finding they would not run and they were a nightmare to debug. So I learnt to write a small bit and then test it. These days I often find myself repeatedly writing a small bit of code then using the compiler to find all the mistakes. That's OK if it picks up a typo but when you start adjusting the parameters types etc just to make it compile you can screw up the design. It also seems that the compiler is creeping into the design process when it should only be used for checking syntax. There's a danger here of over reliance on the compiler to make my programs better. Are there better strategies than this ? I vaguely remember some time ago an article on a company developing a type of C compiler where an extra header file also specified the prototypes. The idea was that inconsistencies in the API definition would be easier to catch if you had to define it twice in different ways.
