  • Lightest weight ubuntu desktop for text editing in big terminal windows?

    - by Kevin Pauli
    I have an older windows laptop onto which I'm installing ubuntu within a VM. My goal is just to use terminal-based linux tools such as vim and shell scripting. I don't give a hoot about any gui for this box. So I first installed ubuntu minimalcd and chose "Basic Ubuntu Server". Upon boot, the text-based terminal came up and I logged in, but the problem is it only gives me 80 columns. I want to do terminal mode vim but have a couple hundred columns to take advantage of my large monitor. If you happen to know how to do that, please see my question here . This post is assuming that the other question is not answerable, and that I will need a desktop to get more than 80 columns in a terminal window. So if that is the case, I want the lightest weight one possible, because this is older hardware and all I want is the ability to have nice big text-based terminal windows for editing text. From the ubuntu minimal CD, I see options for Edubuntu, Kubuntu, etc. Which one of the available desktops would be a good choice for my needs?

  • My Big Break - this is my story and I am sticking to it ;)

    - by dbasnett
    The value of undertaking new and difficult tasks can have many wonderful consequences, don't you agree? Here is the story of my big break. Remember yours? During the mid 70's I was in the Navy and worked as a computer operator at the CNO's Command and Control computer system (WWMCCS) in the Washington Navy Yard. I was a tape ape, but knew that I wanted to be a systems programmer. One day the Lieutenant in charge of the OS group was running a test that required the development system to be re-booted, and I was politely hinting that I wanted out of computer operations. As he watched the accounting tape rewind to BOT and then search for where it had just been (severalminutes) he told me if I would fix "that" he would have me transferred. I couldn't say "Deal" fast enough. Up until then my programming experience had been on Edsger Dijkstra's favorite computer (sic), an IBM 1620. It took almost 6 months of learning the assembler for the Honeywell 6000 and finding the code responsible for rewinding the tape and then forwarding it. After much trial and error at o’dark thirty I succeeded. The tape barely moved and my “patch” was later adopted by many other sites. Lieutenant Jack Cowan kept his promise and I have gone on to have a varied and enjoyable career. To Jack, and the rest of the crew (Ken, Stu, Neil, Tom, Silent W, Mr. Jacobs, Roy, Rocco, etc.) I’d like to thank you all.

  • How to mange big amount users at server side?

    - by Rami
    I built a social android application in which users can see other users around them by gps location. at the beginning thing went well as i had low number of users, But now that I have increasing number of users (about 1500 +100 every day) I revealed a major problem in my design. In my Google App Engine servlet I have static HashMap that holding all the users profiles objects, currenty 1500 and this number will increase as more users register. Why I'm doing it Every user that requesting for the users around him compares his gps with other users and check if they are in his 10km radius, this happens every 5 min on average. That is why I can't get the users from db every time because GAE read/write operation quota will tare me apart. The problem with this desgin is As the number of users increased the Hashmap turns to null every 4-6 hours, I thing that this time is getting shorten but I'm not sure. I'm fixing this by reloading the users from the db every time I detect that it became null, But this causes DOS to my users for 30 sec, So I'm looking for better solution. I'm guessing that it happens because the size of the hashmap, Am I right? I have been advised to use spatial database, but that mean that I can't work with GAE any more and that mean that I need to build my big server all over again and lose my existing DB. Is there something I can do with the existing tools? Thanks.

  • Rendering a big game universe - bitmaps or vector graphics?

    - by user1641923
    I am new to an Android development, though I have much experience with Java, C++, PHP programming and a bit experience with vector graphics too (basic 3d Studio Max, Flash, etc). I am starting to work on an Android game. It is going to be a 2D space shooter/RPG, and I am not going to use any game engines and any 3D party libs. I really want to create a very large game universe, or even pseudo-infinite (without visible borders, as if it were a 2D projection of a sphere). It should include 10-12 clusters of 7-8 planets/other space objects and random amount of single asteroids/comets, which player can interact with and also not interactive background. I am looking for a least complicated aproach to create such a universe. My current ideas are: Simply create bitmaps with space scenery background so that they can be tiled seamlessly repeated and construct my 2D universe of this tiles, then place interactive objects (planets, other spaceships) on it. Using vector graphics. I would have a solid color background, some random background objects and gradients here and there. My problems here: Lack of knowledge of how well vector graphics is integrated in Android. Performance? Memory usage? Does Android manage big bitmaps well? Do all of the bitmaps have to be in memory during all game process? I am interested in technical details regarding each of the ideas and a suggestion, which I should go with.

  • First Project a big one, How much should we charge?

    - by confuzzled
    Two of my cousins and I started a freelance computer repair/web design business just to make some money on the side during college, and received our first major web design project about three weeks ago. Now we've created websites before, but it was mostly for family businesses and have never really charged money, and most of the websites have been static, and don't really require a CMS. This project, however, was a big one (for us anyways). We created a news site that had several categories, we created the banners, we created a classifieds page (not a web app just something static that they control). Several links, a few graphical assets, CSS drop down menu, RSS feed from a different news site, weather, all the normal stuff you would find on a regular news site. On top of that we put in all the usual Joomla stuff (search, Jcomments, Jslide pictures, JCE, etc.). Then we uploaded the first 10 articles they gave us, and we are going to train them how to use Joomla. Now, at first we decided for 700 dollars. I assumed they just wanted a simple blog like website where they can upload articles. But then we had a meeting, and they asked for a lot more. Note: we did not hard code the template from scratch, but customized the gantry framework to fit their needs. We did code quite a bit however. I estimate that we put in about 50-60 hours in total. I'm wondering if 700 dollars is a bit low, this price is definitely not set in stone. Please keep in mind that this is our first project, and we are newbies, please be kind. Thank You!

  • Facebook - Isn't this a big vulnerability risk for users? (After Password Change)

    - by Trufa
    I would like to know you opinions as programmers / developers. When I changed my Facebook password yesterday, by mistake I entered the old one and got this: Am I missing something here or this is a big potencial risk for users. In my opinion this is a problem BECAUSE it is FaceBook and is used by, well, everyone and the latest statistics show that 76.3% of the users are idiots [source:me], that is more that 3/4!! All kidding aside: Isn't this useful information for an attacker? It reveals private information about the user! It could help the attacker gain access to another site in which the user used the same password Granted, you should't use use the same password twice (but remember: 76.3%!!!) Doesn't this simply increase the surface area for attackers? It increases the chances of getting useful information at least. In a site like Facebook 1st choice for hackers and (bad) people interested in valued personal information shouldn't anything increasing the chance of a vulnerability be removed? Am I missing something? Am I being paranoid? Will 76.3% of the accounts will be hacked after this post? Thanks in advance!! BTW if you want to try it out, a dummy account: user: [email protected] (old) password: hunter2

  • Client/Server game even in solo: any big problem?

    - by Klaim
    I'm making a game which have strong basic design based on multiplayer but also should provide a really interesting and self-sufficient solo game. A bit like a real-time strategy game. The events and actions taken shouldn't be as massive and immediate as in a FPS, so you can also think the networking like for an RTS. It's a PC game, targetting Windows, MacOSX and Linux (Ubuntu & Fedora). It's programmed in C++, using a variety of open source libraries, so I have great (potential) control over the performances. So far I always considered that just making the game work with two applications, client & server, even in solo mode was ok. However, as I'm in the process of starting the network code I'm having doubts about if it's a good idea. I'm not a specialist so I might be missing something in my analysis. I see these pros and cons: Pros: The game works only one way so if I fix a bug it should apply on all game modes, whatever the distance with the server is; Basic networking issues would be detected early, including behaviour with the protection softwares (firewall) installed (i am not specialist so this might be wrong); Cons: I suppose that even if it should be really fast enough, networking client and server on the same computer would still be slower than no networking and message passing in (one) process memory. Maybe debugging would be more difficult? I don't have experience in this case but so far I assume that debugging with Visual Studio allows me to debug multiple process so it shouldn't be really different. Also, remote debugging. My question is: is there a big disadvantage that I missed? Or maybe there are advantages that I missed and that should encourage me to just continue with only client-server game sessions?

  • Amazon Upgrades FreeTime; More Content for the Kid-Friendly Walled Garden

    - by Jason Fitzpatrick
    Earlier this year Amazon introduced FreeTime, a walled garden area intended to provide a kids-only app gallery on the Kindle Fire. It was up to parents to populate the content but now, with the recent update, Amazon brings together unlimited books, movies, games, and apps. Intended for children ages 3-8 the upgraded service eschews the you-pick-it-all approach and goes with a hand-curated collection of games, educational apps, books and more. In addition to the pile of hand-curated content, FreeTime also has built in time limits and individual profiles for different children. Every Kindle Fire, Kindle Fire HD, and Kindle Fire HD 8.9″ user can try out the service for thirty days without charge. After the thirty day trial the subscription price is $4.99 per month ($2.99 for Prime members). Hit up the link below to check out the full description of the service.

  • How do I install Zimbra Desktop in an Ubuntu-friendly way?

    - by d3vid
    I'd like to install Zimbra Desktop but I'm worried about picking logical installation locations and how it will integrate with the Unity desktop. If it doesn't appear in the Messaging Menu there isn't much I can do about that, but what about the launcher? There doesn't seem to be PPA or similar resource. These instructions for 10.10 seem complete: http://www.ubuntugeek.com/how-to-install-zimbra-desktop-on-ubuntu-10-10-maverick.html 6 If you would, accept the default directori where it install /opt/zimbra/zdesktop Is this the logical location for Ubuntu? 9 Now you’ll be asked about where to install files, for example: Home//.zdesktop Sounds right. Is it? 10 And then you’ll be asked about the path where to locate the icon where you’ll launch Zimbra, for example: /home//Desktop How about this?

  • A big flat text file or a HTML site for language documentation?

    - by Bad Sector
    A project of mine is a small embeddable Tcl-like scripting language, LIL. While i'm mostly making it for my own use, i think it is interesting enough for others to use, so i want it to have a nice (but not very "wordy") documentation. So far i'm using a single flat readme.txt file. It explains the language's syntax, features, standard functions, how to use the C API, etc. Also it is easy to scan and read in almost every environment out there, from basic text-only terminals to full-fledged high-end graphical desktop environments. However, while i tried to keep things nicely formatted (as much as this is possible in plain text), i still think that being a big (and growing) wall of text, it isn't as easy on the eyes as it could be. Also i feel that sometimes i'm not writing as much as i want in order to avoid expanding the text too much. So i thought i could use another project of mine, QuHelp, which is basically a help site generator for sites like this one with a sidebar that provides a tree of topics/subtopics and offline full text search. With this i can use HTML to format the documentation and if i use QuHelp for some other project that uses LIL, i can import LIL's documentation as part of the other project's documentation. However converting the existing documentation to QuHelp/HTML isn't a small task, especially when it comes to functions (i'll need to put more detail on them than what currently exists in the readme.txt file). Also it loses the wide range of availability that it currently has (even if QuHelp's generated code degrades gracefully down to console-only web browsers, plain text is readable from everywhere, including from popular editors such as Vim and Emacs - i had someone once telling me that he likes LIL's documentation because it is readable without leaving his editor). So, my question is simply this: should i keep the documentation as it is now in the form of a single readme.txt file or should i convert it to something like the site i mentioned above? There is also the option to do both, but i'm not sure if i'll be able to always keep them in sync or if it is worth the effort. After asking around in IRC i've got mixed answers: some liked the wide availability of the single text file, others said that it is looks as bad as a man page (personally i don't mind that - i can read man pages just fine - but other people might have issues reading them). What do you think?

  • Which of these URL scenarios is best for big link menus? [seo /user friendly urls]

    - by Sam
    Hi folks, a question about urls... me and a good friend of mine are exploring the possibilities of either of the three scenarios for a website where each webpage has a menusystem with about 130 links.: SCENARIO 1 the pages menu system has SHORT non-descriptive hyperlinks as well as a SHORT canonical: <a href:"design">dutch design</a> the pages canonical url points to e.g.: "design" OR SCENARIO 2 the pages menu system has SHORT non-descriptive hyperlinks wwith LONG canonical urls: <a href="design">dutch design</a> the pages canonical url points to: dutch-design-crazy-yes-but-always-honest OR SCENARIO 3 the pages menu system has LONG descriptive hyperlinks with LONG canonical urls: <a href="dutch-design-crazy-yes-but-always-honest">dutch design</a> the pages canonical url points to: dutch-design-crazy-yes-but-always-honest Currently we have scenario 2... should we progress to scenario 3? All three work fine and point via RewriteMod to the same page which is fetched underwater. Now, my question is which of these is better in terms of: userfriendlyness (page loading times, full url visible in url bar or not) seo friendlyness (proper indexing due to the urls containing descriptive relevant tags) other concerns we forgot like possible penalties for so many words in link hrefs?? Thanks very much for your suggestions: much appreciated!

  • Pros and cons of creating a print friendly page to remove the use of pdfs?

    - by Phil
    the company I work for has a one page invoice that uses the library tcpdf. they wanted to do some design changes that I found are just incredibly difficult for setting up in .pdf format. Using html/css I could easily create the page and have it print very nicely, but I have a feeling that I am over looking something. What are the pros and cons of setting up a page just for printing? What are the pros and cons of putting out a .pdf? I could also use the CSS inline so that if they wanted to download it and open it they could.

  • How can I easily make printer-friendly pages of any website?

    - by Nathan Fellman
    I tried printing out a short story from http://www.americanliterature.com and it came out with huge margins. The page is set up as a table with 3 columns. The left and right ones have space for ads or menus, and the middle one has the text. When I print it out it makes all the columns the same width. Is there any easy way to get a printer-friendly version of the page?

  • How to better copy&paste big files over RDP?

    - by WebMAOhist
    Recently I was making a few attempts to copy&paste a big (1.2 GB) file to remote computer over RDP. The remote computer is virtual testing machine with MS Windows Server 2008 Datacenter. First I tried to copy&paste before midnight when the transfer speed was limited by client computer ISP to 100 kB/s. So, it required a few hours and I was forced to cancel transfer since remote desktop became too unresponsive and sluggish (slow). So, I re-started it over midnight when my local transfer speed is over 4 GB/s 4MB/s (sorry for typo). So, my impression is that independently on speed (broadband) of copy&paste transfer the remote computer becomes sluggish while copying over RDP. At the same time downloading from internet doesn't make remote host sluggish. AFAIU, it is because clipboard of remote computer and so its memory becomes overloaded by transfer. How can I control (restrict) the usage of clipboard for specific process (pasting of file)? What are the possible way to control it? Update: After reading that slow speed of transfer is caused by encryption used for copy&pasting over RDP and since I believe I am more interested in overall efficiency: both the time, or rapidness, of getting file as well as possibility to work without waiting, I changed the question title from: How to control the usage of remote desktop clipboard usage for pasting a big file? to How to better copy&paste big files over RDP? For example, is it better to copy&paste one huge (zip) archive or unzip it and copy paste a folder with unzipped files? And more exactly I wanted to ask: What are possible ways to improve overall experience: the speed of transfer (i.e. availability of needed file) responsiveness of remote host (making remote coputer available for work before completion of copy&pasting)?

  • Giant online image gallery - How do I avoid OutOfMemoryError?

    - by Ben L.
    For anyone who's wondering, the gallery is http://www.spore.com/sporepedia. My app uses the Spore API to get the 100 newest creations, then displays them in a GridView. The text data about the creations is easy to store, but the images present a problem. As far as I know, I can either keep the images in a Hashtable or grab them every time they are viewed. Neither of these will work - the Hashtable quickly presents an OutOfMemoryError, and the constant reloading causes a lot of load on the server and a lot of lag on the client. Is there a better way to store the images?

  • What is a good way to comment if-else-clauses?

    - by acme
    Whenever I'm writing a typical if-else-construct in any language I wonder what would be the best way (in terms of readability and overview) to add comments to it. Especially when commenting the else clause the comments always feel out-of-place for me. Say we have a construct like this (examples are written down in PHP): if ($big == true) { bigMagic(); } else { smallMagic() } I could comment it like this: // check, what kind of magic should happen if ($big == true) { // do some big magic stuff bigMagic(); } else { // small magic is enough smallMagic() } or // check, what kind of magic should happen // do some big magic stuff if ($big == true) { bigMagic(); } // small magic is enough else { smallMagic() } or // check, what kind of magic should happen // if: do some big magic stuff // else: small magic is enough if ($big == true) { bigMagic(); } else { smallMagic() } What are your best-practice examples for commenting this?

  • How to handle #(hash) character in SEO friendly url?

    - by arvinsim
    How do you bypass the default behaviour if #(hash) which is to go to a specific part of a page? The problem that I have is that the # character is a part of the SEO friendly url which is a title and the #(hash) is part of the content (i.e. like with C#). I can't retrieve the whole string and I only get the characters before the #. Example: www.domain.com/C#-programming-book in this example I only get 'C' and not the '-programming-book' part. I am not using any javascript at the moment and would like to only use a PHP solution for this. Before anyone suggests that I used url encoding, the criteria for the seo friendly url is that it should be human readable and easily remembered. So converting the hash to '%23' does not pass the criteria. Is there no way around it?
