  • Doubling the DPI with a shader?

    - by Mathias Lykkegaard Lorenzen
    I'm developing a game where the map is generated with Perlin Noise, but on the CPU. I am generating some perlin noise onto a texture with a small size, and then I stretch it out to the whole screen to simulate a map. The reason for the CPU generating the noise is that I want it to look the same on all devices. Now, here's the end-result. Please ignore the bullets and the explosion on the picture. What matters is the background (the black/gray pixels) and the ground (the brown-ish pixels). They are rendered to the same texture through perlin noise. However, this doesn't look very pretty. So I was wondering if it would be possible to double the amount of pixels using a shader, and rounding edges at the same time? In other words, improve the DPI. I'm using SharpDX with DirectX 11, through its toolkit feature. But any help that'll lead me in the right direction (for instance through HLSL) would be a great help. Thanks in advance.

  • Why doesn't my grub background show?

    - by luri
    I've tried to change resolution, colors and background image for my grub menu, but I get no background (well, just a black one, no image).... What am I doing wrong? This is my grub.cfg (omitting the OS's part): # # DO NOT EDIT THIS FILE # # It is automatically generated by grub-mkconfig using templates # from /etc/grub.d and settings from /etc/default/grub # ### BEGIN /etc/grub.d/00_header ### if [ -s $prefix/grubenv ]; then set have_grubenv=true load_env fi set default="${saved_entry}" if [ "${prev_saved_entry}" ]; then set saved_entry="${prev_saved_entry}" save_env saved_entry set prev_saved_entry= save_env prev_saved_entry set boot_once=true fi function savedefault { if [ -z "${boot_once}" ]; then saved_entry="${chosen}" save_env saved_entry fi } function recordfail { set recordfail=1 if [ -n "${have_grubenv}" ]; then if [ -z "${boot_once}" ]; then save_env recordfail; fi; fi } function load_video { insmod vbe insmod vga } insmod part_msdos insmod ext2 set root='(hd1,msdos5)' search --no-floppy --fs-uuid --set 42509bf9-f3e6-460a-8947-ec0f5c1fbcc8 if loadfont /usr/share/grub/unicode.pf2 ; then set gfxmode=1280x1024x24 load_video insmod gfxterm fi terminal_output gfxterm insmod part_msdos insmod ext2 set root='(hd1,msdos5)' search --no-floppy --fs-uuid --set 42509bf9-f3e6-460a-8947-ec0f5c1fbcc8 set locale_dir=($root)/boot/grub/locale set lang=es insmod gettext if [ "${recordfail}" = 1 ]; then set timeout=-1 else set timeout=10 fi ### END /etc/grub.d/00_header ### ### BEGIN /etc/grub.d/05_debian_theme ### insmod part_msdos insmod ext2 set root='(hd1,msdos5)' search --no-floppy --fs-uuid --set 42509bf9-f3e6-460a-8947-ec0f5c1fbcc8 insmod jpeg if background_image /boot/grub/Serenity_Enchanted_by_sirpecangum.jpg ; then set color_normal=black/white set color_highlight=brown/light-gray else set menu_color_normal=white/black set menu_color_highlight=black/light-gray fi ### END /etc/grub.d/05_debian_theme ### The selected image has been copied to /boot/grub/Serenity_Enchanted_by_sirpecangum.jpg with no luck.

  • OpenGL profiling with AMD PerfStudio 2

    - by Aurus
    I'm rendering just a really small amount of polygons for my UI but however I still tried to increase the FPS. In the end I removed redundant calls which increased the FPS. I really don't want to lose FPS for nothing so I keep looking for more improvements. The first thing I noticed is the "huge" time where no calls are made before SwapBuffer (the black one). Well I know that OpenGL works asynchronous so SwapBuffer has to wait until everything is done. But shouldn't PerfStudio mark this time also as black ? Correct me If I am wrong. The second thing I noticed is that some glUniform2f calls just take longer (the brown ones). I mean they should all upload 2floats to the GPU how can the time be so different from call to call. The program isn't even changed or something like that. I also tried to look at other programs like gDebugger or CodeXL but they often crashed and they show less statistics (only # of calls or redundant calls etc.) EDIT: I also realized that the draw calls also have different durations, which was obvious for me but sometimes drawing more vertices is faster than drawing less vertices.

  • Transitioning from Internal to Public Speaking

    - by TJB
    For whatever reason, I've always enjoyed giving presentations. As a developer, I've grown from giving the rare presentation when asked to frequently doing 'brown bag' talks and other presentations on new technology, projects etc. I'd like to expand as a presenter and start giving talks in public, outside of just my workplace, and I'm looking for tips on how to get there. At a high level, I'd love to know a good path to take & useful tips to help me grow from just giving internal talks to my group (10-20 people) to eventually be a presenter at medium-large sized conferences. Here are some specific questions, but I will take any advice you can offer: 1. How much experience do I need to speak at user groups etc? I've been in industry for around 5 years, which pales in comparison to most speakers that I normally see. 2. What is a good venue for my 1st public talk? 3. What surprises can I expect when transistioning from speaking to a small group of friends to presenting in public to strangers? I live in southern California and my background is mostly .net / web, so if you have any specific user group / venues those are also greatly appreciated.

  • bubble sort on array of c structures not sorting properly

  • What's wrong with this jQuery? It isn't working as intended

    Using cookies, I want it to remember the colour layout of the page. (So, if they set the gallery one color and the body background another color, it will save that on refresh. But it doesn't seem to be working. jQuery: $(document).ready(function() { if (verifier == 1) { $('body').css('background', $.cookie('test_cookie')); } if (verifier == 2) { $('#gallery').css('background', $.cookie('test_cookie')); } if (verifier == 3) { $('body').css('background', $.cookie('test_cookie')); $('#gallery').css('background', $.cookie('test_cookie')); } $('#set_cookie').click(function() { var color = $('#set_cookie').val(); $.cookie('test_cookie', color); }); $('#set_page').click(function() { $('body').css('background', $.cookie('test_cookie')); var verifier = 1; }); $('#set_gallery').click(function() { $('#gallery').css('background', $.cookie('test_cookie')); var verifier = 2; }); $('#set_both').click(function() { $('body').css('background', $.cookie('test_cookie')); $('#gallery').css('background', $.cookie('test_cookie')); var verifier = 3; }); }); HTML: <p>Please select a background color for either the page's background, the gallery's background, or both.</p> <select id="set_cookie"> <option value="#1d375a" selected="selected">Default</option> <option value="black">Black</option> <option value="blue">Blue</option> <option value="brown">Brown</option> <option value="darkblue">Dark Blue</option> <option value="darkgreen">Dark Green</option> <option value="darkred">Dark Red</option> <option value="fuchsia">Fuchsia</option> <option value="green">Green</option> <option value="grey">Grey</option> <option value="#d3d3d3">Light Grey</option> <option value="#32cd32">Lime Green</option> <option value="#f8b040">Macaroni</option> <option value="#ff7300">Orange</option> <option value="pink">Pink</option> <option value="purple">Purple</option> <option value="red">Red</option> <option value="#0fcce0">Turquoise</option> <option value="white">White</option> <option value="yellow">Yellow</option> </select> <input type="button" id="set_page" value="Page's Background" /><input type="button" id="set_gallery" value="Gallery's Background" /><input type="button" id="set_both" value="Both" /> </div> </div> </body> </html> Thanks so much for the help, I appreciate it. jsFiddle: http://jsfiddle.net/hL6Ye/

  • XSLT and possible alternatives [on hold]

    - by wirrbel
    I had a look at XSLT for transforming one XML file into another one (HTML, etc.). Now while I see that there are benefits to XSLT (being a standardized and used tool) I am reluctant for a couple of reasons XSLT processors seem to be quite huge / resource hungry XML is a bad notation for programming and thats what XSLT is all about. It do not want to troll XSLT here though I just want to point out what I dislike about it to give you an idea of what I would expect from an alternative. Having some Lisp background I wonder whether there are better ways for tree-structure transformations based upon some lisp. I have seen references to DSSSL, sadly most links about DSSSL are dead so its already challenging to see some code that illustrates it. Is DSSSL still in use? I remember that I had installed openjade once when checking out docbook stuff. Jeff Atwood's blog post seems to hint upon using Ruby instead of XSLT. Are there any sane ways to do XML transformations similar to XSLT in a non-xml programming language? I would be open for input on Useful libraries for scripting languages that facilitate XML transformations especially (but not exclusively) lisp-like transformation languages, or Ruby, etc. A few things I found so far: A couple of places on the web have pointed out Linq as a possible alternative. Quite generally I any kind of classifications, also from those who have had the best XSLT experience. For scheme http://cs.brown.edu/~sk/Publications/Papers/Published/kk-sxslt/ and http://www.okmij.org/ftp/Scheme/xml.html

  • Is it worth replacing mouse by standalone trackpad for heavy code-editing? [on hold]

    - by heltonbiker
    I recently got more interested in improving my tools, workspace and worflow. The first sting came with a sore finger due to a crappy keyboard, and then after some research I fell in love with the "mechanical keyboard is what you need" doctrine, bought one (cherry MX Brown if you're curious), and am very happy with the results. Currently I am replacing my previous text editor (Geany) with Sublime Text 3, and am also very happy and feeling much more powerful and professional :) Well, but while I re-read all the ancient debates about VIM vs whatever-else, the following excerpt from a blog post got me thinking again about the mouse vs keyboard, and the "moving around from the very home row" (in VIM) versus gesturing away with the tiny and unstable mouse cursor: Reaching for a mouse may indeed slow you down, but developers are commonly on machines where the trackpad is a micro-hand movement away. Most novice programmers can click on a character on screen faster than an expert Vimmer can type 20jFp; or LkEEE or /word or any other nasty way Vimmers have to use. The point of a mouse is to make arbitrary on screen jumps efficient, and it’s very good at doing that. Don’t you ever think you can beat a mouse. Well, although there is some bitterness in this statement, it makes a lot of sense, and EVEN MORE if you consider your direct input to be a TRACKPAD conveniently placed in front of your spacebar (which oddly is where I like to put my mouse, rotated 90° ccw, due to a serious tendonitis in my right shoulder, already healed, but you knod...). So, the question is: Has anyone replaced mouse by a standalone trackpad, to work in code editing in a desktop machine (that is, with a sandalone keyboard)? Was it worth the change?

  • How to setup a project to use TweetSharp

    - by Stuart Helwig
    I am trying to follow Pete Brown's introductory WPF tutorial which makes use of the TweetSharp libraries to interact with Twitter. I have downloaded what appears to be the latest TweetSharp binaries (and a few others including the ReleaseCandidate) from Codeplex (http://tweetsharp.codeplex.com/). No matter what references I add and no matter what using statements I try, I cannot create a reference to the TwitterService for the FluentTwitter class. I simply get the compiler error - "The type or namespace cannot be found". Now I've noticed that the TweetSharp.dll that Pete references is 518KB but the one contained in each of my different downloads is only 84kb. (I've tried several times - I am getting the full download here). The link from Pete's article to the TweetSharp libraries, no longer works (http://code.google.com/p/tweetsharp/). What basic element am I missing here or what could I be doing wrong?

  • Is it possible to use best_in_place with typeahead from twitter bootstrap?

    - by Dave H
    Basically, I am using best_in_place in my rails webapp to let users edit their profile info in place. The thing is, I would like users to be presented with a typeahead form for certain entries.. Here's what I'm working with: <p>College/University: <input type="text" class="span3" style="margin: 0 auto;" data-provide="typeahead" data-items="8" data-source='["University of Pennsylvania","Harvard","Yale","Princeton","Cornell","Brown","Columbia","Dartmouth"]'></p> This gives me a working form box with typeahead. However, I want to be able to wrap this in best_in_place with something like <%= best_in_place @student, :education %> so that users only see the typeahead form when they click on the text, and upon clicking away from the box or hitting enter the selection is stored in the database. Is there a reasonably easy way to do this?

I have something like this: function cat_filter() { $.ajax({ type: "POST", url: 'json/cat_filter.aspx', data: "catId=" + "&styleId=" + "&colourId=" + "&sizeId=" + "&minPrice=" + "&maxPrice=", dataType: "json", beforeSend: function () { //load loading cursor }, success: function (data) { var CatItems = ""; for (var x = 0; x < data.PRODUCTS.length; x++) { CatItems += '<li class="jcarousel-item jcarousel-item-horizontal jcarousel-item-' + [x] + ' jcarousel-item-' + [x] + '-horizontal jcarousel-item-placeholder jcarousel-item-placeholder-horizontal"><a class="large_image" href="#"><img src="' + data.PRODUCTS[x].product_img + '" alt="' + data.PRODUCTS[x].product_name + '"></a><h3 class="geo_17_darkbrown">' + data.PRODUCTS[x].product_name + '</h3>'; if (data.PRODUCTS[x].product_onsale == 1) { CatItems += '<img alt="sale" src="assets/images/sale.gif" class="sale"><span class="geo_17_red_linethr">&pound;' + data.PRODUCTS[x].product_retailprice + '</span>&nbsp;&nbsp;<span class="price geo_17_darkbrown">&pound;' + data.PRODUCTS[x].product_webprice + '</span>'; } else { CatItems += '<span class="price geo_17_darkbrown">&pound;' + data.PRODUCTS[x].product_webprice + '</span>'; } if (data.PRODUCTS[x].product_COLOURS) { CatItems += '<span class="colour">'; for (var y = 0; y < data.PRODUCTS[x].product_COLOURS.length; y++) { CatItems += '<span><a href="' + data.PRODUCTS[x].product_COLOURS[y].colours_large + '"><img src="' + data.PRODUCTS[x].product_COLOURS[y].colours_thumb + '" alt="' + data.PRODUCTS[x].product_COLOURS[y].colour_name + '" /></a></span>'; } CatItems += '</span>'; } CatItems += '</li>'; } $('.carousel_00 ul').html(CatItems); }, complete: function () { //remove loading cursor } }); } This code generates this html: <div class="carousel_00"> <ul> <li><a href="#" class="large_image"><img src="assets/images/dress1.gif" alt="image"></a> <h3 class="geo_17_darkbrown">Rachel Dress</h3> <span class="price geo_17_darkbrown">&pound;89.99</span> <span class="colour"> <span><a href="assets/images/big_image_1.gif"><img src="assets/images/black.gif" alt="balck"></a></span> <span><img src="assets/images/brown.gif" alt="brown"></span> <span><img src="assets/images/purple.gif" alt="purple"></span> </span> </li> <li><a href="#"><img src="assets/images/dress2.gif" alt="image"></a> <h3 class="geo_17_darkbrown">Rachel Dress</h3> <span class="price geo_17_darkbrown">&pound;89.99</span> </li> <li><img class="sale" src="assets/images/sale.gif" alt="sale" /><a href="#"><img src="assets/images/dress3.gif" alt="image"></a> <h3 class="geo_17_darkbrown">Rachel Dress</h3> <span class="geo_17_red_linethr">&pound;99.99</span>&nbsp;&nbsp;<span class="price geo_17_darkbrown">&pound;89.99</span> </li> <li><a href="#"><img src="assets/images/dress1.gif" alt="image"></a> <h3 class="geo_17_darkbrown">Rachel Dress</h3> <span class="price geo_17_darkbrown">&pound;59.99</span> </li> <li><a href="#"><img src="assets/images/dress2.gif" alt="image"></a> <h3 class="geo_17_darkbrown">Rachel Dress</h3> <span class="price geo_17_darkbrown">&pound;89.99</span> </li> <li><a href="#"><img src="assets/images/dress3.gif" alt="image"></a> <h3 class="geo_17_darkbrown">Rachel Dress</h3> <span class="price geo_17_darkbrown">&pound;89.99</span> </li> <li><a href="#"><img src="assets/images/dress1.gif" alt="image"></a> <h3 class="geo_17_darkbrown">Rachel Dress</h3> <span class="price geo_17_darkbrown">&pound;89.99</span> </li> <li><a href="#"><img src="assets/images/dress2.gif" alt="image"></a> <h3 class="geo_17_darkbrown">Rachel Dress</h3> <span class="price geo_17_darkbrown">&pound;89.99</span> </li> <li><a href="#"><img src="assets/images/dress3.gif" alt="image"></a> <h3 class="geo_17_darkbrown">Rachel Dress</h3> <span class="price geo_17_darkbrown">&pound;89.99</span> </li> </ul></div> What I need is that every 3 li's will be in div /div. I know that this is not semantic and not right, but this is only for example. (Basically if I will figure put how to do this, I will replace li's on spans and that div that i need outside li's on li). Will be very glad if someone will help me. Because code that I have is already too much for me.

  • How can I disable the CTRL-ALT-DEL key combination completely on XP/Vista/7?

    - by Travesty3
    I have been googling extensively to figure this out, and nobody seems to be able to give a direct answer. Let me start by saying that I'm NOT talking about requiring CTRL-ALT-DEL to enter logon information. I'm working on a golf simulator program which is used at golf centers. I need the ability to completely disable the CTRL-ALT-DEL key sequence so that the golf center customers can't get out of the program and access the computer at all. I realize there are other key combinations that need to be handled as well, we already have this entire feature working in XP, but we're going to be switching to Windows 7 soon, and CTRL-ALT-DEL is the only one that doesn't seem to work in Win7. I'd really like an all-around solution if at all possible. This same program may also be installed on a client's personal computer for an in-home golf simulator, but the computers that really need this feature (golf center computers) are provided to the golf center by us, so would the best option be to write a new shell? I don't know anything about that at all, other than others that suggest writing a new shell for kiosk mode. I'd really like a simpler option, like modifying the registry in some way. I have heard that you can remove some buttons from the menu screen that pops up, but unless I can remove pretty much all of them (including the shutdown/restart button in the bottom-right corner), this won't be enough of a solution for me. Thanks for taking the time to read this and thanks again for any help you could provide! -Travis

  • Why am I getting unexpected output trying to write a hash structure to a file?

    - by Harm De Weirdt
    I have a hash in which I store the products a customer buys (%orders). It uses the product code as key and has a reference to an array with the other info as value. At the end of the program, I have to rewrite the inventory to the updated version (i.e. subtract the quantity of the bought items) This is how I do rewrite the inventory: sub rewriteInventory{ open(FILE,'>inv.txt'); foreach $key(%inventory){ print FILE "$key\|$inventory{$key}[0]\|$inventory{$key}[1]\|$inventory{$key}[2]\n" } close(FILE); } where $inventory{$key}[x] is 0 → Title, 1 → price, 2 → quantity. The problem here is that when I look at inv.txt afterwards, I see things like this: CD-911|Lady Gaga - The Fame|15.99|21 ARRAY(0x145030c)||| BOOK-1453|The Da Vinci Code - Dan Brown|14.75|12 ARRAY(0x145bee4)||| Where do these ARRAY(0x145030c)||| entries come from? Or more important, how do I get rid of them?
