  • How can I remove the Unity Launcher?

    - by Magnus Hoff
    I'm running Ubuntu Netbook. With the recent upgrade to 10.10 I was excited about the Application Menu/the global menu bar and its implications for screen real estate. Unfortunately, the Unity Launcher on the left hand side of the screen takes more valuable space away than the new menu bar gives. Is there any way to get rid of the Launcher? Alternatives I would be satisfied with include: Not having the Launcher at all Having the Launcher hide automatically Having applications open on top of the Launcher (not next to it) (edit:) Note that I am specifically looking for a way to keep the global menubar, while getting rid of the Launcher.

  • bootable USB / installation requirements

    - by Chris Wilson
    Originally asked on One Hundred Paper Cuts Answers thread On the official site: http://www.ubuntu.com/netbook/get-ubuntu/download The instructions for creating a bootable USB key for installing Ubuntu Netbook Remix include a line saying: "Insert a USB stick with at least 2GB of free space" I recently installed UNR on a netbook -- in fact, the one I'm using right now -- and I went ahead despite only having a 1GB USB key on hand. Everything went smoothly and installed 100% correctly. If I had waited to go out and buy a 2GB USB key I would have spent that money unnecessarily and wouldn't have been able to use the computer in the meantime. I was wondering if there's a specific rationale for requiring a 2GB USB key, or if the instructions could be changed to indicate that it can be done with only 1GB. Thanks!

  • What's the difference between IEquatable and just overriding Object.Equals() ?

    - by devoured elysium
    I want my Food class to be able to test whenever it is equal to another class. I will later use it against a List, and I want to use its List.Contains() method. Should I implement IEquatable or just override Object.Equals()? From MSDN: This method determines equality by using the default equality comparer, as defined by the object's implementation of the IEquatable.Equals method for T (the type of values in the list). So my next question is: which functions/classes of the .NET framework make use of Object.Equals()? Should I use it in the first place? Thanks

  • Best SEO practices for mobile URLs: 301, rel=canonical, or something else?

    - by Chris
    I am developing a site with a mobile version and am trying to figure the appropriate way to manage the URLs for search engines. So far I've considered: Having a separate mobile site (m.example.com) with rel="canonical" links to the regular site. Putting both the mobile site and full site on one URL (example.com), and doing user agent sniffing. Another opinion: Spencer: "If you have a mobile site at a separate location or URL, you should 301 redirect each and every mobile page to its corresponding page on your main website. Employ user agent detection so that the mobile optimized version is served up if someone's coming in from a hand-held. - http://developer.practicalecommerce.com/articles/1722-Mobile-site-Development-Best-Practices-for-SEO-Usability Both 2 and 3 make it hard for a user who wants to switch to the full site or mobile site manually, but I'm not sure 1 is the best alternative. What's the best way to write URLs for a mobile site?

  • Do we need use case levels or not?

    - by Gabriel Šcerbák
    I guess no one would argue for decomposing use cases, that is just wrong. However sometimes it is necessary to specify use cases, which are on lower, more technical level, like for example authetication and authorization, which give the actor value, but are further from his business needs. Cockburn argues for levels when needed and explains how to move use cases from/to different levels and how to determine the right level. On the other hand, e.g. Bittner argues against use case levels, although he uses subflows and at the end of his book mentions, that at least two levels areneeded most of the time. My questionis, do you find use case levels necessary, helpful or unwanted? What are the reasons? Am I misssing some important arguments?

  • Auto-tiling with Yoshi's Island style tiles

    - by Boreal
    I'm creating a 2D platformer and I'd like to implement an auto-tiling system. Normally, this wouldn't be particularly difficult. However, I'd like to have tiles like in Yoshi's Island, where the graphics extend past the actual collidable tile's boundaries. Consider this image: Although the eggs and the Piranha Plant are clearly resting on the ground, the flower tiles continue behind them, out of the collidable tile. I know that it would be simple to do by hand, but extremely time consuming. Using an auto-tiling algorithm would save me a lot of time and boredom, but I'm not sure where to start.

  • CUPS: HP printer DNS url

    - by wintersolutions
    The URL for my printer generated by hp-makeuri looks like this: hp:/net/Officejet_6500_E710n-z?ip=192.168.178.30 But the printer is on a dhcp enabled wifi network and so its IP-address does and could change. On the other hand my wifi router seems smart enough to have some sort of DNS: $ ping hp-6500a PING hp-6500a.fritz.box (192.168.178.30) 56(84) bytes of data. 64 bytes from hp-6500a.fritz.box (192.168.178.30): icmp_req=1 ttl=255 time=11.3 ms I tried to use the hostname in the CUPS URL/DeviceUID but it failed, any suggestions if this is possible and the correct format?

  • How to Save Hundreds or Thousands of Dollars on Cell Phone Service

    - by Chris Hoffman
    Cell phone contracts are bad. You get a seemingly cheap phone up front, but you more than pay for the cost of the phone over two years. Prepaid phone plans are surging in North America for a reason. Prepaid phone plans will be cheaper and more flexible than traditional contracts with big carriers for many people. However much you use your phone, there’s a good chance you can save money with a prepaid service. No More Contracts Here’s how cell phone service typically works in North America: You get a subsidized phone for “free”, $99, or $199. You sign up for a two-year contract and more than pay back the cost of that phone over the length of the contract. This is similar to leasing something or purchasing it on a credit card and paying it back over two years — you spend less up front, but you’re paying more in the long run. But this isn’t the only option. You could opt for a cheaper prepaid service that doesn’t lock you into a contract. If you don’t use your phone much, you could just pay for what you use and avoid the hefty cell phone bills. If you use your phone a lot, you could get a cheaper plan, too. Now, this certainly isn’t for everyone. If you want the latest iPhone or Galaxy smartphone every two years and require a 4G data connection, prepaid services may not be for you. On the other hand, if you don’t need the latest phone, you can save money here. You can also save a huge amount of money if you don’t use your phone much. Phone Options When you choose your prepaid or contract-free service, you’ll often be able to purchase a phone from them. You’ll generally be able to find dirt-cheap dumbphones and the cheapest, slowest Android phones for not very much money. If you are able to buy a top-of-the-line smartphone, you’ll have to pay the full, unsubsidized price. That’s $649 for either an iPhone 5S or Samsung Galaxy S4. Whatever phones the service provider offers, you could always buy a phone elsewhere — for example, you could buy an unsubsidized iPhone direct from Apple and then take it to your cell phone service of choice. Most services will allow you to get a SIM card and pop it into your existing phone rather than purchasing a phone. If you can get a hand-me-down smartphone, you can often save quite a bit of money. For example, you may have a family member upgrading from an iPhone 4S to an iPhone 5S. You could take their phone to a prepaid carrier and have a nicer phone on a cheap cell phone plan. If you brought an old smartphone to a big carrier like AT&T or Verizon, they wouldn’t give you a discount on your monthly plan. You’d have to pay the same amount of money every month as if you had gotten a subsidized phone. Google’s Nexus phones are also great options for people looking to buy smartphones and pay up-front. Google’s Nexus 4 offered a modern, almost top-of-the-line Android smartphone experience at $299 or $349 when it came out last year. Google will soon be releasing the Nexus 5 and it’s expected to be priced at $349. That’s certainly a lot more than a cheap phone, but it’s a fairly high-end smartphone at almost half the price of an iPhone 5S or Galaxy S4. Nexus phones can be purchased online from Google’s Play Store. Service Options When choosing a service, you need to consider what you actually use. If you’re someone who only uses your phone rarely, you can get plans that will allow you to pay as little as a few dollars per month. If you’re someone who’s usually in range of Wi-Fi, you may not need much data at all. If you want a plan with unlimited talk, texting, and data usage, you can get it for much cheaper than you’d pay on a major carrier like AT&T. The options here range from pay-as-you-go plans, like the ones offered by T-Mobile, which allow you to put a certain amount of money in and only drain that balance when you actually use minutes, texts, or data. If you only make a few calls and send a few texts per month, you’d only pay a few bucks. On the other end, Walmart’s Straight Talk service is a popular option that offers unlimited talk, texting, and data at $45 per month. Which service is right for you depends on a lot of things, including your usage and what each network’s coverage is like in your area. You’ll want to do some research of your own before choosing a service. Prepaid services also offer you even more flexibility after you choose one. If you’re not happy or a better deal comes along, you can switch — you’re not locked into your service for two years and you won’t pay an early termination fee.

  • Opensource showcase for MVC in Java Swing

    - by Regular John
    I've allready created small desktop CRUD applications using Java/Swing. In hindsight I'm not quite sure if the overall design of these applications is good. I've also done some reading on MVC and looked at different Swing-tutorials. My problem is, that I've got a very theroatical knowledge of MVC and on the other hand, most Swing-resources don't implement the MVC-pattern. Now I would like to get my hands dirty and see how MVC is implemented in Swing in a real-world-application. Are there any opensource project you could recommend? It would be also interesting to have more than one project, to see different approaches. Best fit would be a software, that uses a relational database in the backend, to see an overall design, that I can compare to my former applications.

  • DI/IoC in Java for a .NET'er used to Castle.Windsor

    - by Ciddan
    Is there a Java DI container that works in a similar way to the most excellent Castle.Windsor container on the .NET side? The Java containers I've had a look at all seem to rely on annotations (Guice) within my services, which I don't dig all that much - I'd like to go POJO all the way if possible. Spring on the other hand can do without the annotations, but it requires a lot of XML. XML configuration != maintainability. One of the really nice things about Castle.Windsor is the wiring you're able to set up in code with Installers, auto wiring based on naming conventions and whatnot. Ideally the container should also support lifecycle management and configuration; i.e. registering components as transient, singleton, pooled etc. Another bonus would be support for interceptors. Any tips would be greatly appreciated.

  • Proper way to create and work with a subdomain?

    - by Genadinik
    My site got effected by Panda, and I am trying to see if making a subdomain would work. The site is comehike.com, and I created a subdomain which is currently empty at hiking.comehike.com I have a directory /outdoors that has some high quality hand-written articles. I want to put those into the new subdomain to see what would happen. My questions are: Should I just copy and paste the files for those pages into the new subdomain's folder, and just change all the links in all my pages from the original domain to the new subdomain? Should I just do a 301 redirect to the new subdomain? Since test.site.com and www.site.com are different domains, will the new page have to start from scratch in terms of Pagerank, and its rankings in the SERPs?

  • Examples of interesting implementations of character stats?

    - by Tchalvak
    I've got this BBG going ( http://ninjawars.net ), and the character stats currently are simplistic. I'm looking to add a few stats to the current 1/2 (strength and maximum hitpoints, essentially). I've come up with: (strength (unchanged), speed, stamina, and some others that are somewhat interesting wildcard stats). However, I'm not satisfied with how boring the effects of some of these stats are, because they're very linear. Better stat, better effects of the stat, but the stats don't interact with each-other, there's no Rock-Paper-Scissors interaction, having more is always better all the time. So what I'd really like is to see examples of interesting character stats or effects of stats? Examples that I can think of off hand: Call of Cthulu's Insanity stat (things get really weird/chaotic if you start losing sanity) White Wolf stats, to a certain extent (the stats themselves have some basic effects, and all skills effectiveness base themselves off of stats as well) What are some other ways people have used stats to check out?

  • High level project workflow

    - by user775060
    We are a small software company trying our hand at our second game. Since our first games' process was a living nightmare (since we used webdevelopment workflow) I have decided to educate myself on how to manage a game project on a high level. How does your process work, from idea to launch? Preferably in situations where you have a team that needs to cooperate. I've seen these 2 links, which are useful in a way, but was wondering if there are better/more comprehensive ways to do this? http://www.goodcontroller.com/blog/?p=136 http://gogogic.wordpress.com/2009/02/09/symbol6-how-we-created-an-iphone-game/ All input would be infinitely appreciated.

  • What do you do when every possible business idea is already taken?

    - by jonathanconway
    I have a bit of free time and lots of enthusiasm for software and the web. I want to make a start-up, to sell kind of product or online service, but I'm having a hard time coming up with business ideas that haven't already been implemented. For example, I thought of making an e-ordering website for ordering food from restaurants online. Good thing I typed it into Google, because the market is already full of hundreds of websites doing the same thing and competing heavily. The same thing has happened with so many other business ideas I've become excited and passionate about - they're all taken. What's your response to this? Do you agree that all the good ideas seem to be taken? Or do you think there is room for new businesses, and that I'm just not thinking (or looking) hard enough? Have you ever tried idea after idea, only to find that it was already being done, and you had to move onto something else?

  • Blu-ray player?

    - by Dox
    I'd like to play bluray discs in my laptop. I found the official documentation, and there it's explained that one should use mplayer and ffmpeg. Looking at the repositories, there exist two different mplayer packages (in conflict with each other) mplayer mplayer2 Any ideas with of them should I install? On the other hand the official documentation seems to be out of date since no mention to Ubuntu after 9.04 is done. Does the DumpHD package from the repositories work? Finally, Where could the keydb.cfg keys be found? I'm open to suggestions, specially of people who had done the job of making it work. Cheers

  • Geotargeted subfolder questions (Portugal/Brazil and Switzerland)

    - by Lucy
    We are at the beginning of the process to get multilingual versions of a website. We will be using subfolders working off the core domain (eg mydomain.com/fr/), set the geotargeting at webmaster tools and set hreflang attribute. I would really appreciate your help with a couple of questions. 1/Portuguese: we will have a Portuguese language version of the site. Our intention is to use this to cover users in both Portugal AND Brazil. ie, we are not going to do separate folders mydomain.com/pt/ and mydomain.com/br/ Can I use 2 hreflang attributes for this language version to tell Google it covers Brazil AND Portugal? What country code to use for this subfolder? 2/Switzerland Does anyone have best practice advice how to do this? One one hand, the subfolder should be mydomain.com/ch/ but as Switzerland covers 2 language possibilities (French AND German) - what to do? thanks

  • Flash messages in ASP.NET MVC without sessions

    - by Fernando Correia
    I'm developing a web application for Windows Azure using ASP.NET MVC 4. I would like to enforce one restriction in the architecture: do not use Session. To achieve availability on Azure, and since there is no sticky sessions, I would need to store the session data in some central service, probably either SQL Azure or the Caching Service. I would rather avoid sessions on the SQL database to avoid the increased latency, and the caching service on Azure is very expensive for the ammount of memory offered. On the other hand, I would like to have the ability to easily pass Flash-style messages among redirects. TempData is the recommended way to do this, but by default it uses the session object. So I would like to know: Is there an alternative way to use TempData that doesn't require sessions or shared data between servers? Cookies perhaps? Is there a better alternative I'm overlooking?

  • A rather long question about installation/uninstall

    - by user2364312
    Ok so here's the deal guys, last week I decided I want to install Ubunutu again because I really missed it. (Last time I had an ubunutu was 7.somehting) I downloaded 12.04 and isntalled it via bootable usb device. Knowing how dual boots works I cleared up some space on my hard disc before hand using the windows 7 built in disc manager. During Ubunutu's installation I thought that by choosing "Install Ubuntu alongside Windows 7" will automatically just use the space I cleared before, but apperentaly it did not since that partition is still 100% free space. On what partition is Ubunutu installed when using that method? And how can I uninstall it to re-install it back on the space I cleared up for it? Thank you very your time reading and helping!

  • 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.

  • Open Source Web-based CMS for writing and managing API documentation

    - by netcoder
    This is a question that have somewhat been asked before (i.e.: How to manage an open source project's documentation). However, my question is a little different because: We're not developing open source software, but proprietary software The documentation has to be hand-written, because we do not want to publish the actual software API documentation, but only the public API documentation I do want developers and project managers to write the documentation collaboratively Obviously, wikis are a solution, but they're very generic. I'm looking for a more specialized tool for this job. I've looked around and found a few like Adobe Robohelp, SaaS solutions and such, but I'd like to know if any open source software exists for that purpose. Do you know any Open Source Web-based CMS for writing and managing API and software documentation?

  • What's the importance of the "title" tag?

    - by Matteo Mosca
    Talking with some other people recently, it came up an interesting topic. The core question at hand is: What's the real importance and weight of the <title> tag in a web site? For instance, what are the consequences if a site has the same <title> tag on all the pages, reporting only the site name? Or better (or worse) no title tag at all? Will that be a little/medium/huge SEO problem? How will the pages appear on search engines? Will fixing it in a later stage be problematic since pages have already been indexed? How does it compromise the overall usability/accessibility/experience? Is that a "feature" that can be omitted, or it can't even be considered a "feature" but a core element? I have quite my opinion on this topic, but I'd really love to hear what other experts (you) think about it.

  • How do you answer "Rate yourself" questions?

    - by Vinoth Kumar
    Hi , I have been frequently asked questions like "Rate yourself in java" It goes like interviewer : Rate yourself in java on the scale of 10 me: 9 interviewer : Rate yourself in J2EE me : 8 .... But really I just come up with arbitrary numbers. Sure I know Java well , but what does it mean to say "9 out of 10" . I think it is a very subjective question, that does not make sense overall. The problem is ,if I say 9 , If I am not able to answer any question , the interviewer might think , "this guy just said 9" . On the other hand If I said 6 , there is a good chance the interviewer might think "He rates himself this low...not good" How do you respond to such questions ?

  • Wine: How to open a whole folder, not a single file?

    - by Boris Karl Schlein
    I am using foobar2000 under my Ubuntu with Wine since… I don't know. Now, with the new Ubuntu 12.10 release foobar2000 was not starting anymore correctly so I reinstalled it (foobar2000 1.1.15, wine 1.4). Naturally I have to set up my foobar2000 configuration from scratch but thats not a problem at all. Everything works fine except adding whole folders to the music library using the Add-button under "File-Preferences-Media Library". Problem is one can only open files with the Add-dialog but not a whole folder. Under Windows everything works fine. Editing the foobar2000 configuration file ([foobar2000-folder]/configuration/Core.cfg) by hand does not work… I also tried it with a hex editor. :( So… what can I do? Thanks. :)

  • Establishing relationships with unsolicited recruiters

    - by Michael
    Several times each year, I receive unsolicited introductions from tech recruiters, usually via LinkedIn and usually local firms. I am not currently looking for a new job. Is it advisable to establish a relationship with one or more recruiters when I'm not interested in finding new work, so that they have my resume on file? Here's another way I approach the question: My plumber was first hired at the point of need: I had a plumbing problem, looked up a few of them, and evaluated and hired based on their demeanor and cost estimates. I established a relationship with a general attorney, on the other hand, well in advance of ever actually needing services so that if or when services are needed he already knows enough about me to begin work. Should I approach recruiters like I approached my plumber or my lawyer? A separate discussion, I suppose, is whether or not the type of recruiters who troll LinkedIn for clients are generally helpful or not. Edit: I have never worked with a recruiter before, and therefore have little idea what to expect.
