• What is your solution to the FizzBuzz problem?

  - by saniul

  See here Write a program that prints the numbers from 1 to 100. But for multiples of three print "Fizz" instead of the number and for the multiples of five print "Buzz". For numbers which are multiples of both three and five print "FizzBuzz". Disclaimer: I do realize this is easy, and I understand the content of the Coding Horror post I just linked to

• lexers vs parsers

  - by Naveen

  Are lexers and parsers really that different in theory ? It seems fashionable to hate regular expressions: coding horror, another blog post. However, popular lexing based tools: pygments, geshi, or prettify, all use regular expressions. They seem to lex anything... When is lexing enough, when do you need EBNF ? Has anyone used the tokens produced by these lexers with bison or antlr parser generators?

• CodeCharge : is it any good?

  - by David Burrows

  Hi, A job came in to me that's built with CodeCharge - had a look at it and seems to be a pretty basic point-and-click site builder tool. Has anyone got any in-depth experience with it? My first reaction is one of horror and to just rebuild the code in Rails or PHP but I thought I'd ask the question first, maybe i'm missing something...

• Script to Change Pronunciations on Mac

  - by user106990

  So I've been looking around on how to change how my mac says things, I have found my answer but what I need is some help with the coding. Here is what I want to do: Create a list of word pairs. Create a script that substitutes words in its parameter list according to your word-pairs list, and passes the modified parameter list to "/usr/bin/say". I This is a quick copy of http://superuser.com/q/170041/106990 and I have very little coding know how and would like some help. I don't care in what language. Any help would be really appreciated. Thanks in advanced.

• to measure throughput of testing device connect to server via AP

  - by samantha

  Description of project- I have a test tool to which DUT connects. The test tool has an access point in it and once DUT get connected to it via mac address we check RSSI and some other features of WiFi of DUT. Now I am wondering is there is any way I can measure throughput of Device under test via mac address of DUT from server side. Test-tool has LINUX fedora 11 in it and major coding is done in c/C++ and json command. Previously, I have tried to install ftp server on test-tool and DUT can connect to it and we can measure the throughput or data transfer rate, but this is not feasible solution as it requires lot of intervention from DUT. What I am interested in is 1) To run some script on server side /test tool and it gives me throughput of bandwidth of connected device may be via mac address of DUT OR 2) Server script transfer some files/packets to DUT and we can measure the throughput. Coding is not a major challenge at this stage , I just need some tool which requires minimum intervention from DUT.

• What's the worst working environment you've had to suffer?

  - by John

  We'll leave "worst job ever" for another day if it wasn't already done... but after some recent discussions on good environments, what is the worst you've had? I've always been quite lucky - seats that go up and down, some kind of natural light, etc. But I think I dodged a bullet... what horror stories can you share?

• Most suitable Unix platform for developing device drivers

  - by bugspy.net

  I completely newbie in device drivers, so I hope my question is in place, but I need to develop a driver to control some equipment. I was thinking on using Linux as the host OS, but not sure if it is such good idea. I've heard some horror stories about the mess of developing device drivers under Linux. Is there a better alternative under the *Nix world? Or maybe should I check other OSes?

• How do i keep a newly started program from taking focus?

  - by Jugglingnutcase

  Say i'm coding in emacs and want to start up a music program. Because it takes too long to start up i go back to coding and type away. When the music application starts up, the focus is stolen (gasp! stolen!) away from emacs and goes to the music application, often mid-thought. Is there any way to keep this from happening and have the newly started application not have focus until i see that it's up and ready to be used? Besides getting rid of my ADD of course. Or getting an impossibly fast computer that can keep up with my mind. i'm using a Windows XP system, but i will soon have a Windows 7 system, and i have Linux at home.

• How can I make XSLT work in chrome?

  - by Eric

  I have an XML document here that is served with a corresponding XSL file. The transformation is left to be executed client-side, without JavaScript. This works fine in IE (shock horror), but in Google Chrome, just displays the document's text nodes. I know that it is possible to do client-side XSL in Chrome, as I have seen examples of it, but I am yet to be able to replicate this success myself What am I doing wrong?

• What popular "best practices" are not always best, and why?

  - by SnOrfus

  "Best practices" are everywhere in our industry. A Google search on "coding best practices" turns up nearly 1.5 million results. The idea seems to bring comfort to many; just follow the instructions, and everything will turn out fine. When I read about a best practice - for example, I just read through several in Clean Code recently - I get nervous. Does this mean that I should always use this practice? Are there conditions attached? Are there situations where it might not be a good practice? How can I know for sure until I've learned more about the problem? Several of the practices mentioned in Clean Code did not sit right with me, but I'm honestly not sure if that's because they're potentially bad, or if that's just my personal bias talking. I do know that many prominent people in the tech industry seem to think that there are no best practices, so at least my nagging doubts place me in good company. The number of best practices I've read about are simply too numerous to list here or ask individual questions about, so I would like to phrase this as a general question: Which coding practices that are popularly labeled as "best practices" can be sub-optimal or even harmful under certain circumstances? What are those circumstances and why do they make the practice a poor one? I would prefer to hear about specific examples and experiences.

• What do we call to "non-programmers" ? ( Like "muggle" in HP ) [closed]

  - by OscarRyz

  Sometimes I want to refer to people without coding powers as Muggles. But it doesn't quite feel right. Gamers have n00b ( but still a n00b has some notion of gaming ) I mean, for all those who Windows in the only OS in the world ( what's an OS ? would they ask ) For project manager who can't distinguish between excel and a database. For those who exclaim "Wooow! when you show them the ctrl-right click to see the webpage source code. What would be a good word to describe to these "persons without lack of coding ability?" Background I didn't mean to be disrespectful with ordinary people. It's just, sometimes it drives me nuts seeing coworkers struggling trying to explain to these "people" some concept. For instance, recently we were asked, what a "ear" was (in Java). My coworker was struggling on how to explain what is was, and how it differ from .war, .jar, etc. and talking about EJB's application server, deployment etc, and our "people"1 was like o_O. I realize a better way to explain was "Think about it as an installer for the application, similar to install.exe" and he understood immediately. This is none's fault, it is sometimes our "poeple" come from different background, that's it. Is our responsibility to talk at a level they can understand, some coworkers, don't get it and try very hard to explain programming concepts ( like the source code in the browser ). But I get the point, we I don't need to be disrespectful. ... But, I'm considering call them pebkac's 1As suggested

• OTN Developer Days (Review) - San Juan, PR - April 29, 2010

  - by dana.singleterry

  A quick update on the San Juan, PR event. First off it was a great success with the Keynote audience of 200+. Mickey Ralat, Managing Director Oracle Caribbean, kicked off the event with a quick introduction followed by me delivering the Keynote Message - The Fusion Development Platform which is the first session in the regular OTN DD events that we run in North America. Following this session was a partner, SDT, basically marketing their services which covers the Oracle stack and then following was a very brief presentation on APEX. After this we broke out into the various tracks of Java, (APEX) DB SQL Developer, .NET on Oracle. After the breakout we ran the following sessions in the Java track: Developing with JDBC, UCP, and Java in Database, Rich Internet Applications in Web 2.0, Development Made Simple Without Coding: Developing Reusable Business Components. As expected with the various tracks, we ended up with 50 - 70 in the various sessions within the JAVA track and the audience was very impressed with the power of JDeveloper/ADF 11g and we got a number of questions from licensing cost to upgrading / integrating from Forms. As for the Forms questions, I fielded a number of them and for those I couldn't, I pointed them towards Grants resources which seemed to suffice. They were all, for the most part, unaware of the recent 11.1.1.3 release which occurred only a couple of days prior to the event. The indication was that they were going to download it and use it for the lab that was included on the DVD which we did not have the time for them to even start on. For those of you that attended the event, you can download the updated presentations as follows: Keynote - The Fusion Development Platform Rich Internet Applications in Web 2.0 Development Made Simple Without Coding - Developing Reusable Business Components

• Silverlight layout hack: Centered content with fixed maxwidth

  - by brainbox

   Today we need to create centered content with fixed maxwidth. It is very easy to implement it for fixed width, but is not clear how to achieve the same for maxwidth.The solution to the problem is Grid with 3 columns: <Grid>      <Grid.ColumnDefenitions>            <ColumnDefenition Width="0.01*" />             <ColumnDefenition Width="0.98*" MaxWidth="1280" />            <ColumnDefenition Width="0.01*" />      </Grid.ColumnDefenitions> </Grid>Huh... like html coding xaml coding is still full of dirty tricks =)

• Time management and self improvement

  - by Filip

  Hi, I hope I can open a discussion on this topic as this is not a specific problem. It's a topic I hope to get some ideas on how people in similar situation as mine manage their time. OK, I'm a single developer on a software project for the last 6-8 months. The project I'm working on uses several technologies, mainly .net stuff: WPF, WF, NHibernate, WCF, MySql and other third party SDKs relevant for the project nature. My experience and knowledge vary, for example I have a lot of experience in WPF but much less in WCF. I work full time on the project and im curios on how other programmers which need to multi task in many areas manage their time. I'm a very applied type of person and prefer to code instead of doing research. I feel that doing research "might" slow down the progress of the project while I recognize that research and learning more in areas which I'm not so strong will ultimately make me more productive. How would you split up your daily time in productive coding time and time to and experiment, read blogs, go through tutorials etc. I would say that Im coding about 90%+ of my day and devoting some but very little time in research and acquiring new knowledge.

• Advice on selecting programming languages to concentrate on? (2nd year IT security student)

  - by Tyler J Fisher

  I'm in the process of considering which programming languages I should devote the majority of my coding studies to. I'm a 2nd year CS student, majoring in IT security. What I want to do/work with: Intelligence gathering Relational databases Virus design Snort network IPS Current coding experience (what I'm going to keep): Java - intermediate HTML5 - intermediate SQL (MySQL, Oracle 11g) - basic BASH - basic I'm going to need to learn (at least) one of the following languages in order to be successful in my field. Languages to add (at least 1): Ruby (+Metasploit) C++ (virus design, low-level driver interaction, computationally intensive applications) Python (import ALL the things) My dilemma: If I diversify too broadly, I won't be able to focus on, and improve in a specific niche. Does anyone have any advice as to how I should select a language? What I'm considering + why I'm leaning towards Ruby because of Metasploit support, despite lower efficiency when compared to Python. Any suggestions based on real-world experience? Should I focus on Ruby, Python, or C++? Both Ruby, and Python have been regarded as syntactically similar to Java which my degree is based around. I'm going to be studying C++ in two years as a component of my malicious code class. Thanks, Tyler

• How can i be sure that professional programming is not for me ?

  - by user17766

  Hello everybody I love programming, developing projects for hobby and learning new concepts. I am getting harder too much in current job Despite learnt many thing well. I can even hardly understand assigned tasks. I am asking why i am getting harder to myself. It may not my fault? Our architecture doesn't spend enough time to explain complicated sides of project for us or i am not enough smart one for understand fastly. Our architecture also doesn't know what kind of hell he is creating ? Seeing 3 level generic types and 4-5 level generic inheritance in domain model objects hell makes me think so really. It looks abusing concepts more than reduce complexity. Thinking that he hasn't experienced before such a big project while he is getting confused in problems of the project. May i am not in right company ? May i am not good programmer ? May i am really stupid ? Become good in programming concepts is not enough to deal big project's complications so someone should to tell me that i have to still effort too much even i am good programmer for adopting myself to any big project ? Also i had another bad experiences from previous job but my professional experiences is almost few months but i spend 2 years for learning and coding for fun and i really can say that i have well skills on OOP, Design Patterns, coding standards and deep knowledge in language currently used. Sometimes i am thinking to leave programming professionally and work in any lame job while doing programming just for hobby. Waiting suggestions and insights

• How to handle people who lie on their resume [closed]

  - by Juliet

  Moderator comment Please note that this is a two year old question that has just been migrated from Stack Overflow. Please take your time to read all the answers and ask yourself "would my answer add anything to this?". I'm conducting technical interviews to fill a few .NET positions. Many of the people I interview really do know .NET pretty well, but I find at least 90% embellish their skillset anywhere between "a little" to "quite drastically". Sometimes they fabricate skills relevant to the position they're applying for, sometimes they don't. Most of the people I interview, even the most egregious liars, are not scam artists. They just want to stand out among the crowd, so they drop a few buzzwords on their resume like "JBoss", "LINQ", "web services", "Django" or whatever just to pad their skillset and stay competitive. (You might wonder if a person that lies about those skills is just bluffing their way through a technical interview. My interviews involve a lot of hands-on coding and problem-solving – people who attempt to bluff will bomb the hands-on coding portion in the first 3 minutes.) These are two open-ended questions, but it would really help me out when I make my recommendations to the hiring managers: Regarding interviewing etiquette, should I attempt to determine whether a person really possesses all of the skills they claim to have? Can I do this without making the candidate feel uncomfortable? Regarding the final decision, should I recommend candidates who are genuinely qualified for the positions they're applying for, even if they've fabricated portions of their skillset?

• Teaching myself, as a physicist, to become a better programmer

  - by user787267

  I've always liked physics, and I've always liked coding, so when I got the offer for a PhD position doing numerical physics (details are not relevant, it's mostly parallel programming for a cluster) at a university, it was a no-brainer for me. However, as most physicists, I'm self taught. I don't have broad background knowledge about how to code in an object oriented way, or the name of that specific algorithm that optimizes the search in some kD tree. Since all my work so far has been more concerned about the physics and the scientific results, I undoubtedly have some bad habits - more so because my coding is my own, and not really teamwork. I have mostly used C since it is very straightforward and "what you write is what you get" - no need for fancy abstractions. However, I have recently switched to C++ since I'd like to learn more about the power that comes with abstraction, and it's pretty C-like (syntax-wise at least). How do I teach myself to code in a good, abstract way like a graduate in computer science? I know my code is efficient, but I want it to be elegant as well, and readable. Keep in mind that I don't have time to read several 1000-page tomes about abstract programming. I need to spend time on actual, physics related research (my supervisor would laugh at me if he knew I spent time thinking about how to program elegantly). How do I assess if my work is also good from a programmer's perspective?

• multi user web game with scheduled processing?

  - by Rooq

  I have an idea for a game which I am in the process of designing, but I am struggling to establish if the way I plan to implement it is possible. The game is a text based sports management simulation. This will require players to take certain actions through a web browser which will interact with a database - adding/updating and selecting. Most of the code required to be executed at this point will be fairly straightforward. The main processing will take place by applications which are scheduled to run on the server at certain times. These apps will process transactions added by the players and also perform some automatic processing based on the game date. My plan was to use an SQL server database (at last count I require about 20 tables) and VB.net for all the coding (coming from a mainframe programming background this language is the simplist for me to get to grips with). I will also need a scheduling tool on the server. Can anyone tell me if what I am planning is feasible before I dive into the actual coding stage of my project?

• I'm learning html and I'm confused as to how href's work. [migrated]

  - by Robolisk

  Okay so i'm learning html right now and soon css. In my html coding I have a section like this for navigation: <div id="header"> <h1>Guild Wars 2 Fanbase</h1> <ol id="navigation"> <li><a href="/">Home</a></li> <li><a href="/facts">Facts</a></li> <li><a href="/gallery">Gallery</a></li> <li><a href="/code">Coding</a> <ul><li><a href="/code/line">Lines</a></li> <li><a href="/code/comment">Comment Lines</a></li> </ul> </li> </ol></div> Now when I open up this .html file this is all layed out the way I want it too look (the mark up that is). My question is this, when I click on a link on this site (this site being this code) I get an a error saying this webpage is not found, but of course. But how do I create it so I can have the web pages working together? I'm not sure how to word it correctly. Like, do I create another .html file in the same directory so somehow when I click the link it reads from the second .html file? If you not sure what I'm asking, just let me know and I'll try to be more specific. Thank you for your help (: excuse my mistakes in grammar, not the worlds best in English, trying my best (:
