• Is it worth being computer languages polyglot?

  - by Anton Barkowski

  You can often hear that programmers should learn many different languages to improve themselves. I still go to school and don't have big programming experience (a little more than year). But what was noble intention to improve programming skills turned into some kind of OCD: I feel that I won't calm down until I learn all relatively known programming languages. And here is question itself: Will being programming languages polyglot actually help you (And I don't mean usual "Programmer should know at least all paradigms", I mean really all languages you usually hear about)? Does anybody have similar experience? Does it help with job/skills/career? How often are you able to apply those skills?

• Enable wifi on my computer - firmware missing

  - by Sarah

  I am attempting to set up a wireless network on 11.04, freshly download today. The router is on and working. However, I do not have a wifi "card" (which I am assuming is a little USB-type thing that allows internet access, but correct me if I am wrong) and every time I try to type in the MAC address and everything, nothing works. I also get the "firmware missing" error when I scroll over the signal strength, which I have tried looking up but have been unsuccessful with completely understanding it. I guess my main question is do I need another little device to be able to use wifi on my ubuntu? I do have an ethernet cable but another person is using it and I do not want to be tied down to that cable. the problem is that none of the wireless networks show up, however they show up when I go into Windows mode on my laptop. I get an error message at the top saying "firmware missing" which I have tried looking up but still have no straight answer for.

• Adding cards to a vector for computer card game

  - by Tucker Morgan

  I am writing a Card game that has a deck size of 30 cards, each one of them has to be a unique, or at least a another (new XXXX) statement in a .push_back function, into a vector. Right now my plan is to add them to a vector one at a time with four separate, depending on what deck type you choose, collections of thirty .push_back functions. If the collection of card is not up for customization, other than what one of the four suits you pick, is there a quicker way of doing this, seems kinda tedious, and something that someone would have found a better way of doing.

• The Best Websites for Downloading and Playing Classic and New Text Adventure Games

  - by Lori Kaufman

  Before computers could handle graphical games, there were text adventure games. The games are interactive stories, so playing a text adventure game is like being part of a book in which you affect the story. Text adventure games are also referred to as “interactive fiction.” Interactive Fiction (IF) is actually a more accurate term for text adventure games, because these games can cover any topics, such as romances or comedies, not just adventures. They can also simulate real life. Even though computers can now handle intensely graphical games, playing text adventure games can still be fun. It’s like reading a good book and getting lost in the universe of the story, except you become the hero or heroine and affect the ending of the story. We’ve collected some links to websites where you can download classic and new text adventure games or play them online. There are also some free tools available for creating your own text adventure games. We even found a documentary about the evolution of computer adventure games and some articles about the art and craft of developing the original text adventure games.

• Toshiba External Hard Drive freezes computer

  - by Ephraim

  I bought a Toshiba Canvio Basics E05A032BAU2XK Portable External 320GB 2.5 Hard Drive: My computer has two Os's on it Win7 and Win XP. I need both. The main one I use is XP. When booting my computer in any OS the computer and hard drive work fine. The same holds true for plugging in the hard drive while running Win7. However, when running WinXP, if the hard drive gets plugged in the computer freezes(my main point is that the HD is portable so it is essential that it does not do this, as I said I usually run XP). After reading some online forums I was informed that there is a compatibility issue with the newest version of Eset Smart Security(I still don't understand this because it works fine in Win7 or when connected on boot...). I disabled the AV and plugged in the HD... Walla! The comnputer did not freeze. However the disk is not recognized in explorer or disk management. In device manager I removed the device and did a scan and installation of device failed. It pretty much sounds like a driver issue but I cannot find any drivers for this HD. In fact, Toshiba claims that there are no downloadable drivers for it and that XP should take care of the drivers itself. What to do? As far as I can tell, all other USB devices work just fine on both OS. Please Help!

• How do I explain what's good about F#?

  - by Ramon Snir

  Many people ask me to explain to them why is F# (or other functional languages) better (or different) than other languages they know (like Java, C#, C++). Until today, I either tried showing few examples or using longs scary words or lending Tomas Petricek's book, but I find those ways either time consuming or unclear. Is there a simple(r) way to explain functional programming to imperative programmers?

• What are some good Photo and Artwork APIs?

  - by Ryan T

  We had an idea for starting a ecards service and were looking into the possibility of populating our site using photo/artwork APIs. Due to legal reasons, Flikr probably won't work, although I've started to scour the web for other options. Basically we just need two functions the user should be able to browse the site's collection and choose a picture we should be able to recall and render a specific picture on our site. From there we should have no problem building our application. The main obstacle is that we're lacking content at the moment. I haven't been able to find too many examples of this being done, so I was wondering if anyone here might know people who have done something similar to what we're trying to do, or know of any leads that might be able to help us out. Suggestions for other APIs that are out there, or forums/communities that might be able to point us in the right direction are also welcome.

• Does TDD lead to the good design?

  - by Eugen Martynov

  I'm in transition from "writing unit tests" state to TDD. I saw as Johannes Brodwall creates quite acceptable design from avoiding any of architecture phase before. I'll ask him soon if it was real improvisation or he had some thoughts upfront. I also clearly understand that everyone has experience that prevents to write explicit design bad patterns. But after participating in code retreat I hardly believe that writing test first could save us from mistakes. But I also believe that tests after code will lead to mistakes much faster. So this night question is asking for people who is using TDD for a long time share their experience about results of design without upfront thinking. If they really practice it and get mostly suitable design. Or it's my small understanding about TDD and probably agile.

• Windows 7: Setting up backup to an external hard drive on another computer on the network

  - by seansand

  I have an external hard drive connected to a Windows 7 (Home Edition) computer. I have another computer (with Windows 7 Ultimate), and I want to have the Windows 7 Ultimate back up to the same external hard drive, without having to disconnect and move the external hard drive from the Home Edition PC. When I get to the "Set up backup" dialog within Windows 7, it asks me where to save the backup. I select "Save on a network". However, when I enter "\\computername\harddrivename" under Browse, the "OK" button remains grayed out. The button remains grayed out unless I also enter a Username and Password under "Network credentials". However, the account I have on the other computer doesn't have a password for it. To un-gray out the button I must enter a fake password, allowing me to click "OK", but then obviously I get a "bad password" error. Does anyone know how to get around this problem? (Seems kind of ridiculous.) I made sure that the security settings with the external hard drive on the other computer are full access to Everyone, so permissions is not the problem. I also thought about using Homegroup instead of the regular security settings, but there is no obvious way to go about it that way, either.

• Good Scoop: The PeopleSoft/IBM Backstory

  - by [email protected]

  By Brian Dayton on April 12, 2010 11:15 AM Sometimes you're searching for something online and you find an unrelated, bonus nugget. Last week I stumbled across an interesting blog post from Chris Heller of a PeopleSoft consulting shop in San Ramon, CA called Grey Sparling. I don't know these guys. But Chris, who apparently used to work on the PeopleTools team, wrote a great article on a pre-acquisition, would-be deal between IBM and PeopleSoft that would have standardized PeopleSoft on IBM technology. The behind-the-scenes perspective is interesting. His commentary on the challenges that the company and PeopleSoft customers would have encountered if the deal had gone through was also interesting: · "No common ownership. It's hard enough to get large groups of people to work together when they work for the same company, but with two separate companies it is much, much harder. Even within Oracle, progress on Fusion applications was slow until Thomas Kurian took over Fusion applications in addition to Fusion middleware." · "No customer buy-in. PeopleSoft customers weren't asking for a conversion to WebSphere, so the fact that doing that could have helped PeopleSoft stay independent wouldn't have meant much to them, especially since the cost of moving to whatever a "PeopleSoft built on WebSphere" would have been significant." · "No executive buy-in. This is related to the previous point, but it's worth calling out separately. If Oracle had walked away and the deal with IBM had gone through, and PeopleSoft customers got put through the wringer as part of WebSphere move, all of the PeopleSoft project teams would be put in the awkward position of explaining to their management why these additional costs and headaches were happening. Essentially they would need to "sell" the partnership internally to their own management team. That's not a fun conversation to have." I'm not surprised that something like this was in the works. But I did find the inside scoop and Heller's perspective on the challenges particularly interesting. Especially the advantages of aligning development of applications and infrastructure development under one roof. Here's a link to the whole blog entry.

• A good interpreted language for a small embedded project

  - by Earlz

  I have an mbed which has a small ARM Cortex M3 on it. Basically, my effective resources for the project are ~25Kb of RAM and ~400Kb of Flash. For I/O I'll have a PS/2 keyboard, a VGA framebuffer(with character output), and an SD card for saving/loading programs(up to a couple of Mb maybe) The reason I ask this here is because I'm trying to figure out what programming language to implement on the thing. I'm looking for an interpreted language that's easy for me to implement, and won't break the bank on my resources. I also intend for this to be at least possible to write on th device itself, though the editor can be interpreted(yay bootstrapping) Anyway, I've looked at a few simple languages. Some nice candidates: Forth BASIC Scheme? Has anyone done something like this or know of any languages that can fit this bill or have comments about my three candidates so far?

• Is sticking to one language a good practice?

  - by Ans

  I'm developing a pipeline for processing text that will go into production. The question I keep asking myself is: should I stick to one language when looking for a tool to do a particular task (e.g. NLTK, PDFMiner, CLD, CRFsuite, etc.)? Or is it OK to mix and match looking for the best tool regardless of what language it's written in (e.g. OpenNLP, ParsCit, poppler, CFR++, etc.) and warp my code around them?

• Bay Area JUG Roundup 2010 - A Good Time for All

  - by Justin Kestelyn

  The first Bay Area JUG Roundup (#roundup10) convened at Oracle HQ on Wednesday evening, in the palatial surroundings of the Oracle Conference Center. (Yes, there will be more!) A couple hundred people were there, I'd say. More came out of this meetup than a bunch of new contacts and some mild indigestion (or even a mild hangover): - We (meaning, Oracle) announced the opening of the eight annual Duke's Choice Awards. As described on the Web page, "The awards celebrate extreme innovation in the world of Java technology and are granted to the best and most innovative projects using the Java platform." Entries will be accepted through July 1, with winners announced at JavaOne 2010. - Even more exciting, we offered a sneak preview of the Java Road Trip, a cross-country, 20-stop bus tour this Summer involving one rock-star bus, one full-time blogger/videographer, a whole bunch of Java demos and speakers, and lots of beer and prizes. Stay tuned for more info about this. - Sonya Barry, Java.net community manager, announced the beta.java.net project - which will be the end result of the java.net migration to a Kenai back-end and retooled social/community layer (already in progress). Sonya also announced that Maven support for Java.net projects is imminent, with just a contract to be signed in the next couple of weeks. Finally, we were all treated to a typically hilarious Java Posse appearance. Arun Gupta has posted photos as well as meetup slideware at his blog. And as soon as the video replay (thanks, Steve Chin) and Java Posse podcasts are available, I'll post links to those here too.

• Good and easy way to share files on local machine

  - by jb

  I would like to have a directory that has following properties: Many users can copy files into it These files can be deleted/changed by these users (user A can delete/modify file that was copied into this directory) it cant be done using normal file permissions (because permissions are retained on copy). Here is what I found on the net: brainstorm idea blueprint Some use cases: Sharing music on local machine Simple git repository sharing (just make a bare repository writeable to many people) --- i know that there are solutions like gitosis Allow many developers to modify test instance of php app without giving them root (i guess they would copy files) --- I'm leading a team of nonprofit junior developers and I need to keep that one simple! EDIT AFAIK setting SGID bit is not enugh, it only affects newly created files --- and basic workflow for these use cases ivnolves copying and other operations (which cleave file's gid unchanged)

• How to write good code with new stuff?

  - by Reza M.

  I always try to write easily readable code that is well structured. I face a particular problem when I am messing around with something new. I keep changing the code, structure and so many other things. In the end, I look at the code and am annoyed at how complicated it became when I was trying to do something so simple. Once I've completed something, I refactor it heavily so that it's cleaner. This occurs after completion most of the time and it is annoying because the bigger the code the more annoying it is the rewrite it. I am curious to know how people deal with such agony, especially on big projects shared between many people ?

• Is "no installation" software a good thing?

  - by Yaron Naveh

  I am building an application that will, hopefully, be used by developers. To be appealing to developers I want it to be lightweight, small in size, and with no installation (e.g. xcopy). I trust more an application without installation to not put garbage in my registry, to be lightweight etc. My friend thinks the opposite: An installer puts shortcuts on the desktop / menu for me, it ensures cleanup via the uninstaller, and seems more official. I'm curious - what is everyone's take on this?

• Good practices while working with multiple game engines, porting a game to a new engine

  - by Mahbubur R Aaman

  I have to work with multiple game engines, like Cocos2d Unity3d Galaxy While working with multiple game engines, what practices should i follow? EDIT: Is there any guideline to follow, that would be better as while any one working with multiple game engines? EDIT: While a game made by Cocos2d and done well at AppStore, then our target it to port to other platforms, then we utilize Unity3D. Here what should we do?

• How to create a good sitemap for dynamic website

  - by Saif Bechan

  I have a website with dynamic content and different kind of pages. I have some pages that rarely change, and I have pages like blogs that change often. The blog pages also have links for sorting, for example sorting on date, asc, desc. On some of the pages I also have links to different tabbed content, and links that are just anchor links. Now when I use a xml sitemap generator then all the links are thrown into the site, and so I don't think all the links are really relevant. The blogposts up until now are also taken into the sitemap. Is this really necessary? I think the links to the blogposts can be indexed just fine. Is the best way to make a sitemap just to manually assign the main menu links to the sitemap, or is indexing everything really recommended?

• Advice on a good comeback strategy after years of java abstinence

  - by simou

  It's almost 5 yrs since I left the java IT-project/enterprise business. Before I was a highly skilled enterprise developer / OO architect with more than 10 years experience in the business. I was proficient in many of those enterprise related technologies, including DWHing. Since then I haven't been doing any large scale programming, a little bit of C, Python, some dips into Scala, hacking a small java-plugin framework, opengl, but only as fun projects. Now I want to re-enter the java stage again, i.e. I'm looking for job opportunities as a developer. But I fear I might have lost much of my former punching strength, e.g. I would have to give my SQL knowledge a deep refreshing breath, re-visit basic stuff like design patterns, enterprise architectures, etc. and probably learn the new stuff like EJB3.1, JEE 6 too. I also missed the whole scrum craze. So from your own experience, what subject should I tackle first? Like technology (which ones?) or design skills (uml..)? But what I'm also wondering is since the basic design / architectural principles haven't changed much by now, what would be the chance on the job market for someone like me who left the java-world at a time where everything was less fragmented and EJB2.1 and XDoclet were de-facto standards? And how could I convince a potential employer that I'm still an effective on-the-job learner? Should I rather aim for "junior positions" ? Lots of questions but I'd be really glad if you could share your (encouraging :) thoughts with me. cheers! (btw I'm based in Austria)

• Computer Boot/Installation Failure

  - by Marcus

  I recently tried to insatll Kubuntu and it failed. It completely removed everything off of my HDD and there is no operating system. Everytime I try to install a Distro it fails during instillation. I got Ubuntu 13.04 to work but it required a reboot and after that it did not work. I tried to re-install Ubuntu but it failed. I have tried Ubuntu, Kubuntu, and Xubuntu and they all failed. With Kubuntu and Xubuntu I get an error saying, "The 'grub-efi-amd64-signed' package failed to install into /target/. Without the GRUB boot loader, the installed system will not boot". When I select try (distro) it loads up but the installation won't finish. I do not want to have to try the distro everytime I want to get on it. Any help?

• A good substitute for ASMX web service methods, but not a general handler

  - by Saeed Neamati

  The best thing I like about ASP.NET MVC, is that you can directly call a server method (called action), from the client. This is so convenient, and so straightforward, that I really like to implement such a model in ASP.NET WebForms too. However, in ASP.NET WebForms, to call a server method from the client, you should either use Page Methods, or Web Services, both of which use SOAP as their communication protocol (though JSON can also be used). There is also another substitution, which is using Generic Handlers. The problem with them however is that, a separate Generic Handler should be written for each server method. In other words, each Generic Handler works like a simple method. Is there anyway else to imitate MVC model in ASP.NET WebForms? Please note that I can't change to MVC platform right now, cause the project at our hand is a big project and we don't have required resources and time to change our platform. What we seek, is a simple MVC model implementation for our AJAX calls. A problem that we have with Web Services, is the known problem of SoapException, and we're not interested in creating custom SoapExctensions.

• games and rendered surfaces get slow after having computer on for some time

  - by eyecreate

  I have an i5 2500K and nvidia 9600 GT with proprietary driver. For some reason, this set up on 12.04(and was same on 11.10) seems to work fine on boot up, but after about 30 mins of use, games and other accelerated surfaces start running at about 5fps. This is fixed by a reboot to start it all over again. Is there some way I can get rid of this, as I don't have this problem with other systems with Ubuntu?

• Good questions to ask a potential new boss?

  - by David Johnstone

  I first asked this question on Stack Overflow, but it turns out this is a better place for it. Imagine you were working as a software developer. Imagine that the manager of your team leaves and your company is looking for a replacement. Imagine that as part of the hiring process you had the opportunity to talk with him. You are not the only person doing an interview, and while it is not ultimately your decision whether or not to hire him, you do have an influence. What questions would you ask? What would you talk with him about?
