  • How to use multiple monitors effectivelly

    - by maaartinus
    I'm currently using a single monitor, since I see no value in something like this mentioned in this answer. It may be a good exercise for my neck, but besides of this I see no use therein at all. This amounts to 5760x1200 pixels, which is nearly 7M pixels, just fantastic, except for me not being a cyklop-han. The ratio of 24:5 is IMHO too bad for this to be usable. I don't even think that two 16:10 monitors side by side is a good idea. I never tried so I may be completely wrong, but I suppose that the 4:3 ratio would be much better for this. Or even 1:1, but no such thing is available (with some exceptions, either very expensive or very low resolution). Does anybody use two monitors arranged vertically (resulting in 16:20)? or two pivoted monitors side by side (resulting in 20:16)? or another such variant?

  • Robots.txt and "Bad" Robots

    - by Lynda
    I understand robots.txt and its purpose. I have read some people saying that using a Robots.txt gives "bad" robots or robots who do not obey a robots.txt a way to access pages on your site that you do not want accessed. While I am not looking to get into a debate about that I do have a question: If I have a structure like this: /Folder/ /Sub-Folder 1/ /Sub-Folder 2/ (Note: There are no pages within /Folder/ only other folders.) If I Disallow: /Folder/ it will prevent "good" robots from accessing the directory and any contents within the sub-folders. While we know that bad robots will see the /Folder/ will they be able to see and acess the sub-folders and the pages within the subfolders if they are not listed in the robots.txt? (Note: I do not fully understand how robots good or bad crawl a site beyond using a robots.txt and links within the site.)

  • How to best prepare for the GRE Computer Science Subject Test?

    - by Maddy.Shik
    How do I prepare for the GRE Computer Science subject test? Are there any standard text books I should follow? I want to score as competitively as possible. What are some good references? Is there anything that top schools like CMU, MIT, and Standford would expect? For example, Cormen et al is considered very good for algorithms. Please tell me standard text books for each subject covered by the test, like Computer Architecture, Database Design, Operating Systems, Discrete Maths etc.

  • Is it Hard to Write a Blog?

    - by Joe Mayo
    Responding to a tweet I received, asking if I found it hard to write a blog and keep it interesting. This is one of the situations where a 140 character response doesn’t do a question justice. There’s a lot to think about between the subjects of writing, subject matter, and entertainment.  Here’s my take on each of these three topics: There’s all types of writing you can do with various degrees of difficulty. If you’re writing a book and you have a gazillion editors bleeding over your every utterance, then the task becomes harder because you’re second-guessing yourself, not knowing whose opinion will be violated. However, if you’re communicating in a public forum, not too many people care about the grammar as much as whether what you have to say is correct.  For a blog, I would say it’s somewhere in-between.  Right now, I’m using Windows Live Writer, which gives me a few advantages to just typing into the blog editor, such as spelling correction and the ability to save my work and resume later.  Overall, writing is one of those things that you just need to get used to.  It’s an essential skill for developers because you need to document your work, depending on what your definition of proper documentation is, and communicate with other developers via various communications mediums. Not begin good (or not thinking that you’re good) shouldn’t hold you back.  Like most things in life, practice will improve your skill.  So, push away that inner voice that keeps you from moving forward and just do it. A good grasp on the subject matter you’re writing about helps.  However, don’t let a lack of knowledge stop you from writing about something. I recall reading something a while back by a developer who didn’t know a technology but wrote about their experience in learning it. They ended up learning more by expressing their thoughts in writing. If you look around out many blogs today, there are many items written by developers learning what they’re writing about.  So, whether you are sure or unsure, you can still write – just be honest with yourself and your readers about what you’re writing. Also, don’t be afraid to have a different opinion or worry if someone will disagree.  I’ll freely admit that it took a while for me to become accustomed to being criticized. Take the good with the bad and use the bad to make yourself better. Guaranteed, someone will disagree with one or more parts of what I’ve written here or think they have a better approach. No problem, more power to them, and whatever constructive comments they have will be a benefit to me in the future; Otherwise, to h*ll with them. :)  Every time you get knocked down, get right back up, dust the dirt off your backside, and keep moving forward.  You’ll learn in time how to align a subject with your own presentation of the material. Entertainment could be hard or could be natural, depending on the personality of yourself and your target audience. It’s even more challenging because you can say something you think is funny and someone will be offended. In fact, there are a lot of things that you shouldn’t say in the name of a joke, but I won’t mention any of them here for want of not offending anyone. Of course, I probably offended someone by saying that and there is probably an organization somewhere in the world out to get me now. I’m probably not the best person to be giving you advice on entertaining an audience.  I mean, every time I try to tell a joke on Twitter 10 people unfriend me. Okay, maybe 15, but you get my point. One thing you might be interested in knowing is that it’s not too hard for one technical person to entertain other technical people, especially when the subject is of interest.  It’s the excitement in each sentence and passion in each paragraph that will keep another developer entertained and interested in what you have to say. Not everyone will like what you’ve written, but the important part is to find your own voice and it’s likely that there is one person in some corner of the world that likes what you have to say, even if it’s your mom and she doesn’t understand a single word you write. :)   If I could leave you with one final thought; Just do it and don’t let anyone or anything hold you back.   Joe

  • Dealing with a developer continuously ignoring edge cases in his work

    - by Alex N.
    I have an interesting, fairly common I guess, issue with one of the developers in my team. The guy is a great developer, work fast and productive, produces fairly good quality code and all. Good engineer. But there is a problem with him - very often he fails to address edge cases in his code. We spoke with him about it many times and he is trying but I guess he just doesn't think this way. So what ends up happening is that QA would find plenty issues with his code and return it back for development again and again, ultimately resulting in missed deadlines and everyone in the team unhappy. I don't know what to do with him and how to help him overcome this problem. Perhaps someone with more experience could advise? Thank you!

  • Books and stories on programming culture, specifically in the 80's / early 90's

    - by Ivo van der Wijk
    I've enjoyed a number of (fiction/non-fiction books) about hacker culture and running a software business in the 80's, 90's. For some reason things seemed so much more exciting back then. Examples are: Microserfs (Douglas Coupland) Accidental Empires (Robert X. Cringely Almost Pefect (W.E. Peterson, online!) Coders at Work (Peter Seibel) Today I'm an entrepeneur and programmer. Back in the 80's a I was a young geek hacking DOS TSR's and coding GWBasic / QBasic. In the 90's I was a C.S. university student, experiencing the rise of the Internet world wide. When reading these books running a software business seemed so much more fun than it is nowadays. Things used to be so much simpler, opportunities seemed to be everywhere and the startups seemed to work with much more real problems (inventing spreadsheets, writing word processors in assembly on 6 different platforms) than all our current web 2.0 social networking toys. Does anyone share these feelings? Does anyone have any good (personal) stories from back then or know of other good books to read?

  • Where and how to mention Stackoverflow participation in the résumé?

    - by Sandeepan Nath
    I think I have good enough reputation on SO now - here is my profile - http://stackoverflow.com/users/351903/sandeepan-nath. Well, this may not be that much as compared to so many other users out there but I am happy with mine. So, I was thinking of adding my profile link on my résumé. (Just the profile link and not that "I have this much reputation on SO"). Those who haven't seen, can see this question Would you put your stackoverflow profile link on your CV / Resume?. How would this look like? Forums/Blogs/Miscellaneous others No blogging as yet but active participant in Stackoverflow. My profile link - http://stackoverflow.com/users/351903/sandeepan-nath I think of putting this section after Project Details and Technical Expertise sections. Any tips/advice? Thanks Update MKO has made a very good point - "do you really want a potential employeer to be able to evaluate in detail everything you've ever written on SO". I thought of commenting but it would be too long - In my questions/answers I put a lot of statements like - "AFAIK ...", "following are my assumptions so far ...", "am I correct to conclude that... ?", "I doubt if it is possible to ..." etc. when I am not sure about something and I rarely involve in fights with other users. However I do argue on topics sometimes if I feel it is necessary and if I have a valid point. I do accept my mistakes and apologize for the same. As we all know nobody is perfect. I must have written many things which may be judged as wrong by a potential employer. But what if the same employer notices that I have improved in the quality of content by comparing old content with new one? Isn't that great? I also try to go back to older questions/answers and put corrective comments etc. when I feel I was wrong or if I can improve my post. Of course there are many employers who want you (potential employees) to be correct each and every time. They immediately remove you from consideration when you say a single incorrect thing. I have personally met such an interviewer few months back. He didn't even care to listen to any good thing I had done after he found a single wrong thing. Now the question is do you really care to work with such people? Or do you like those people who give value to the fact that you are striving to improve every day. I personally prefer the latter.

  • English to French translation of computing terminology

    - by Rich
    I work in France as a Java programmer, mainly in French, but am a native English speaker. My level of French is pretty good (French wife!), but one thing I have problems with is working out whether to use English terminology or a French equivalent. Examples: lock (as in a synchronisation lock) - do I use the verb "locker" or do I use verrouiller? shard (databases) - "un shard" or "un tesson" (which means a shard of glass) ...and so-on... So, what do people recommend? Can anyone point out some good websites for translating this kind of terminology? The usual online translation tools are a bit too everyday English/French, not the slightly more specialised version that I find myself needing.

  • Learning Python from Beginner to Advanced level

    - by Christofer Bogaso
    I have some problems in my hand and would like to resolve them by myself (rather than hiring some professional, obviously due to cash problem!): build a really good website (planning to set-up my own start-up). build some good software (preferrably with exe installation files) on many mathematical and statistical techniques. To accomplish those tasks, is it worth to learn Python in advance level? I have advanced programming experiences with R and Matlab and VBA (and some sort of C), however not anything on Python. Be very grateful if experts put some guidance here. Thanks for your time.

  • Java - learning / migrating fast

    - by Yippie-Kai-Yay
    Hello! This is not one of those questions like "How do I learn Java extremely fast, I know nothing about programming, but I heard Java is cool, yo". I have an interview for a Java Software Developer in a couple of weeks and the thing is that I think that I know C++ really good and I am somewhat good at C# (like, here I can probably answer on a lot of questions related to these languages), but I have almost zero experience with Java. I have a lot of projects written in both languages, I participiated in several open-source projects (mostly C++, though). Now, what should I do (in your opinion) to prepare myself for this Java interview. I guess migrating from C# to Java should be kind of fast, especially when you know a lot about programming in global, patterns, modern techniques and have a lot of practical experience behind you. But still two weeks is obviously not enough to get Java in-depth - so what should I focus on to have the best chances to pass the interview? Thank you.

  • Need help to install Ubuntu on Win7 Alienware M17xR3, installing not working

    - by Rodrigo
    Please I need help to install linux on my computer to start analyzing Next Generation Sequencing (molecular genetics) for my work. I've tried to install from all different ways and forms and it gave me different errors. First I will describe my system: Alienware M17x R3 Raid Drive 596GB (2x 298 GB) Windows7 primary partition C: The hardrive is divided in 3 primary partitions (can't do 4 don't know why) 1st: Fat16 no name capacity 40mbs almost not used (has files like command.com, dellbio.bin, dellrmk.bin and oobedone.flg) I dont know what this is for but is blocked and non system (Status:none). 2nd: Recovery NTFS 9GB (Status:system) and it seems to have boot files. 3rd: CD: Windos OS (status:boot). And I have 2 Logical drivers F: data for backup and games :D (300gb) G: For trying to install the Linux (Already tried with Fat32, Ext2, ext3 and ext4) Installing with Wubi on F: and G: Instalation looks good on windows ask to restart dos mode appears: try (HD0,0) non-ms:skip try (HD0,1) NTFS5: No Wibildr try (HD0,2) NTFS5: Error: "Prefix" is not set. Installing with Wubi on C: Installation looks good on windows ask to restart dos mode apears: Mount denied becouse NTFS volume is already exclusive opened, the volume may be already mounted or another software may use it which could be identified for example by the help of the 'FUSER' command Mount devdm-4 Could not find installation files /ubuntu/install custom-installation Run 'Chkdsk /r' on windows and restart...blablablalba... that should correct. done this didn't work. Tried installing with USB drive and after burning a CD with the Iso file download from the official website: I've tried the option to install along windows with a G: drive in FAT32, EXT2,3 and 4, I've tried to leave unallocated data, without the driver G at all... appears this everytime: http://i.stack.imgur.com/eo2Ie.png pres ok it ask me to: Not possible to install the boot loader at the location: specify new location: I've tried to select all the drivers non is accepted If I ask to continue without installing the boot loader he ask me to install later by myself which I'm trying to figure it out but I'm not really good to understand how ppl get to the programming part like a DOS to write down couse I'm a newb and I've dont work on dos or linux before... I've read that the boot loader has to be installed on the primary partition, but I'm not sure what I can delete from those 2 partitions that would let me get 1 extra... and it seems that the one that windows use is protected to write down so the software is not touching it... Please if someone have any idea to help me out... I've got a course tomorrow of how to use the software to analyze the data and I wanted to take my computer with me, so I've passed the last 3 days trying to search different ways to solve. My question is also post on the bugs.launchpad.net link here: lounchpad.net bug #882695

  • Does syntax really matter in a programming language?

    - by Saif al Harthi
    One of my professors says "the syntax is the UI of a programming language", languages like Ruby have great readability and it's growing, but we see a lot of programmers productive with C\C++, so as programmers does it really matter that the syntax should be acceptable? I would love to know your opinion on that. Disclaimer: I'm not trying to start an argument. I thought this is a good topic of discussion. Update: This turns out to be a good topic. I'm glad you are all participating in it.

  • Travelling MVP #2: Community event at Bucharest, Romania

    - by DigiMortal
    My second trip was to DevReach with two stops. My first stop was at Bucharest where I met with my friend Dimitar Georgiev who is one of authors of Gym Realm service. Romanian MVP Andrei Ignat was our host there and organized meeting with local community guys. With me – it was first time in my life – was one more guy from Estonia visiting DevReach and he made the whole trip with me. Bucharest We arrived to Bucharest 29.09 at night. We stayed at Hotel Michelangelo. It’s small hotel with nice rooms, free WiFi and very good service. Although my room was on the first floor there was no street noise. We visited one restaurant that offers national cuisine and it was really great. Next day we went out with local guys and had some beers in “old town”. Bucharest “old town” is nice and cozy. There are many bars open and I am sure everybody will find there some very okay place. After supper we visited one warm karaoke bar where we had beers with local guys. Andrei Ignat – karaoke star Agu Suur and Andrei Ion Rinea enjoying karaoke and tequila Community event Next day we had community event. I made my session about ASP.NET Web API and Dimitar told about how to port ASP.NET web applications to cloud environment. Sessions were held at study class of one local company. Dimitar Georgiev speaking about porting web apps to Windows Azure. As it was usual community evening and not some bigger event there were about 12 guys attending from Bucharest. There were both IT-PROs and developers and one nice thing about Bucharest community is that they are listening to you very well and they ask questions if something is unclear or if you slide over from topic they are interested in. Okay, we tried to keep up good tempo so people stay awake and I think we succeeded. After sessions we went all together to local Piranha pub that was near event venue. We had some beers with local guys and talked with them on different technology topics. It was another good and interesting evening at Bucharest. I want to go back there for sure. As it was my first trip to Bucharest and mostly I gathered experiences I think my next community trip there will be way stronger. I take it as a challenge. Plus – I have there some new friends and I want to meet them too – be it community event or not. :)

  • Free or Low Cost Web Hosting for Small Website [duplicate]

    - by etangins
    This question already has an answer here: How to find web hosting that meets my requirements? 5 answers I have a small website (between 2000 and 10000) page-views a day. I'm looking for a free or low cost web host. I tried 50webs.com but their server breaks down. So as not to cause debate, I am also just looking for links to good information sources for web hosting if just finding a good web host is too general. I currently only use HTML, CSS, and JavaScript though I'm considering learning PhP and other more advanced languages to step up my game.

  • Connect Team Foundation Service/TFS 2012 with Visual Studio 2010 &amp; Visual Studio 2008

    - by Vishal
    Hello, Microsoft finally released the Team Foundation Service in late October 2012 after its long time in the preview phase. I was already using the TFS Preview which was free but I was happy to see Microsoft releasing the Team Foundation Service also FREE for upto 5 users. Isn't that great news? I know there are bunch of other free source control repositories (Github, Bitbucket, SVN etc.) out there but I somehow like TFS better. Also the other good thing about the final release was that I didn’t had to do any kind of migration of my code from preview to final release version. Just changed the TFS connection URL and it worked like a charm. Anyways, if you are a startup with small team and need some awesome Source Control along with all the good Project Management, Continuous Integration (Build, Test, Deploy), Team Collaboration, Agile/Scrum planning etc. features than Team Foundation Service is your answer. Microsoft has not yet released their pricing for more than 5 users and will be releasing it sometime in early 2013. What if as of now you have a team more than 5 users and you want to use Team Foundation Service, the good news is you can use it for FREE but when they release the final pricing, you will have to transition to the paid plan. Lot of story, getting to the point, connecting to Team Foundation Service with Visual Studio 2012 is straight forward and would work out of the box but it wont for previous versions of Visual Studio. You will have to upgrade to the latest service pack first and than install the forward compatibility pack. (1st : Service Packs & 2nd: Forward Compatibility packs) For Visual Studio 2010: Visual Studio 2010 Service Pack 1. Visual Studio 2010 forward compatibility for TFS 2012 and Team Foundation Service.         For Visual Studio 2008: Visual Studio 2008 Service Pack 1. Visual Studio 2008 forward compatibility for TFS 2012 & Team Foundation Service. Restart your system. Visual Studio 2008 will not work if you only put https://xxx.visualstudio.com. You will have to put your collection name too as shown below.       By the way, it doesn’t matter if you are an Apple Application Developer or Android App Developer, you can still use Team Foundation Service as your source control. Below are few links to connect to Team Foundation Service with other IDEs: Connect Eclipse to Team Foundation Service. Connect XCode to Team Foundation Service. Happy coding. Vishal Mody

  • Cool examples of procedural pixel shader effects?

    - by Robert Fraser
    What are some good examples of procedural/screen-space pixel shader effects? No code necessary; just looking for inspiration. In particular, I'm looking for effects that are not dependent on geometry or the rest of the scene (would look okay rendered alone on a quad) and are not image processing (don't require a "base image", though they can incorporate textures). Multi-pass or single-pass is fine. Screenshots or videos would be ideal, but ideas work too. Here are a few examples of what I'm looking for (all from the RenderMonkey samples): PS - I'm aware of this question; I'm not asking for a source of actual shader implementations but instead for some inspirational ideas -- and the ones at the NVIDIA Shader Library mostly require a scene or are image processing effects. EDIT: this is an open-ended question and I wish there was a good way to split the bounty. I'll award the rep to the best answer on the last day.

  • What are the best social places for programmers to interact?

    - by Chevex
    I know this is not really the right place for this type of question, but I figure it will get me started and hopefully won't be closed right off the bat. I love the programming industry a lot, but I don't have many colleagues that aren't introverted and/or anti-social, or self-centered. What are some good places online to find programming friends that I could share my adventures with? I love stack overflow but it is more technical and doesn't really allow you to put up a personal project just for people to see and critique. Any suggestions? A good forum would be great! The only ones I can find are usually full of inexperienced people who just "want" to be a programmer. I'm looking more for a place who's members are already programmers discussing programming topics.

  • Developing an ELO like point system for a multiplayer gaming site

    - by Alejandro Piad
    I'm currently working on a gaming site where users will submit virtual players for different games, like Chess, Nash, Backgammon, Go, etc. The idea is that users don't compete themselves, but through their virtual players. There will be leagues, tournaments, and other competition formats. The question is which would be a good rating system for users in this environment. Take into account that every user may have many different virtual players playing in many different games. As a general guideline I would like to guarantee the following properties: Users who have a lot of mediocre players should not score higher than users with a few very good players. A user with a high rating should not be penalized if he adds a new bad player, until he has had enough time to improve his player. Users who don't play often should not score higher than users who play every day. Thanks in advance.

  • HTML5 or Native Android/iOS application?

    - by Dimitris
    I would like to hear your opinion on this debate. I want to build a mobile application which will interact with a server and I was wondering what's the best way to do it. Build the entire application using the HTML5 technology and then just create native "browsing" apps for Android/iOS or to build the Android/iOS apps from scratch? Using the HTML5 will save considerable amounts of time but I don't know if the result will be equally good in both platforms. Building native apps will take much more time but the result will be definitely good. What do you think?

  • Beginning HTML and CSS [closed]

    - by romani
    My goal of learning HTML and CSS is to be able to modify popular scripts such as Wordpress, vBulletin, Drupal, etc. I haven't started yet learning CSS and HTML or XHTML. I see many, many books and tutorials out there so it is difficult to make a choice. I think most of web designers were like me in the past and have read many books. So, could you tell me about 1 good book for HTML and 1 good book for CSS? and if I should read the book from cover to cover or only learning the basics is enough for modifying Wordpress, for example!

  • What are the safety benefits of a type system?

    - by vandros526
    In Javascript: The Good Parts by Douglas Crockford, he mentions in his inheritance chapter, "The other benefit of classical inheritance is that it includes the specification of a system of types. This mostly frees the programmer from having to write explicit casting operations, which is a very good thing because when casting, the safety benefits of a type system are lost." So first of all, what actually is safety? protection against data corruption, or hackers, or system malfunctions, etc? What are the safety benefits of a type system? What makes a type system different that allows it to provide these safety benefits?
