• What happened to GremCheck? Is there a viable replacement?

  - by goober

  I was a big fan of an app called "GremCheck" that was out a while back, that seems to have disappeared. It was a JavaScript included in a master page that placed an icon at the bottom of the page. It was used during testing. You could define your own tests, and the box could pop up per page and viewers would answer the questions you define (such as "Does this page have the correct title?", "Is the Grammar Correct", "Does the design look consistent"). This was useful for end-user tests groups and quick testing for developers if time was squeezed on full functional testing. Anyone know where GremCheck went, if I can get to it, and if there's anything out there that does something similar?

• Resize a RAID 1 volume on OSX Snow Leopard - how? (Note: software raid)

  - by Emmel

  I've scoured the Internet in search of an answer to this question, and as usual with OSX-related topics, I often don't find any deep-dive technical explanations sufficient enough to feel confident doing dangerous things. Here is my question: I have a Mac Pro, running OSX 10.6.2. I have, as my main root/boot disk, a RAID 1 volume called "Mirror1". Mirror1 is comprised of two 1 TB disks. Mirror1, however, is fixed at 640 GB. That's because, I originally took a 640GB disk, bought a terabyte disk, mirrored it (using diskutil appleraid enable...), when it synced I removed the 640GB and replaced it with a second 1 TB disk, and synced again. Voila! A single 640 GB replaced by two 1 TB disks in a mirror.. Actually, no. There's still something missing from the equation: Mirror1 needs to be expanded from 640GB to 1 TB to match the partition sizes on each of those disks. How do I do this? Perhaps the diskutil output will help: -> diskutil list /dev/disk0 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *1.0 TB disk0 1: EFI 209.7 MB disk0s1 2: Apple_RAID 999.9 GB disk0s2 3: Apple_Boot Boot OSX 134.2 MB disk0s3 /dev/disk1 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *1.0 TB disk1 1: EFI 209.7 MB disk1s1 2: Apple_RAID 999.9 GB disk1s2 3: Apple_Boot Boot OSX 134.2 MB disk1s3 /dev/disk2 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *640.1 GB disk2 1: EFI 209.7 MB disk2s1 2: Apple_HFS Mac Disk 2 536.7 GB disk2s2 3: Microsoft Basic Data BOOTCAMP 103.1 GB disk2s3 /dev/disk3 #: TYPE NAME SIZE IDENTIFIER 0: Apple_HFS Mirror1 *639.8 GB disk3 -> diskutil appleraid list AppleRAID sets (1 found) =============================================================================== Name: Macintosh HD Unique ID: 1953F864-B474-4EB6-8E69-41834EBD0247 Type: Mirror Status: Online Size: 639.8 GB (639791038464 Bytes) Rebuild: manual Device Node: disk3 ------------------------------------------------------------------------------- # Device Node UUID Status ------------------------------------------------------------------------------- 0 disk1s2 25109BAE-5697-40EA-B612-0217851444F7 Online 1 disk0s2 11B83AB0-8148-4DB6-8761-DEF08C855F8D Online =============================================================================== Thanks in advance.

• Unable to create context rendering error when run OpenGL application

  Hello, I try to run Mesa gears example and I get following error: freeglut (./gears): Unable to create direct context rendering for window 'Gears' This may hurt performance. though the application runs successfully, but I guess that in future I will have much problems with productivity. I run Linux CentOS 5 on WMvare 7. Mesa's version is 6.5 Relevant output of lspci -v gives: 00:0f.0 VGA compatible controller: VMware SVGA II Adapter (prog-if 00 [VGA controller]) Subsystem: VMware SVGA II Adapter Flags: bus master, medium devsel, latency 64, IRQ 9 I/O ports at 10d0 [size=16] Memory at d0000000 (32-bit, non-prefetchable) [size=128M] Memory at d8000000 (32-bit, non-prefetchable) [size=8M] [virtual] Expansion ROM at 30000000 [disabled] [size=32K] Capabilities: [40] Vendor Specific Information Any one have idea? There is driver of vmvare for CentOS? Thank you for ahead.

• Acceptable sound quality: stereo needed for an Android game?

  - by Thomas Calc

  I have various simple short sound effects (damage sound, dying sound, thunderbolt, fanfare, breaking) for a game that is developed for Android currently. I use OGG files: 96kbps VBR, 44.1KHz, 2 channels (that means stereo, right?). I read the other stackexchange topics about "acceptable sound quality", but they're too general, address too many things. My experience is that even with 80kbps, my effects sound OK. But I tested it on a limited number of Android devices (including a Sony Ericsson Xperia Neo and a HTC Desire HD). My questions: For mobile phones and tablets, generally, what parameters are recommended? Won't my 80kbps sounds be bad on a newer device (such as a modern tablet)? I don't hear any difference between stereo and mono (2 channels vs. 1 channel, right?), is there any noticeable difference at all for mobile phones / tablets? (in terms of the player experience) May it worth it at all? I assume that stereo sounds take much more in memory (when they're decoded to PCM), despite of the fact that the compressed OGG size is practically the same. Reacting to Roy T.'s great comment: Actually, I couldn't measure the PCM size (Android decodes OGG internally), but I thought that stereo will take more space than mono when uncompressed After throwing out one of the WAV channels in Audacity, and re-exporting it: The new WAV file size is half than before The OGG file size is practically the same as before The sound effects and game music was recorded by my friend who is an experienced hobby musician/composer, but he knows little about computers & software so he just gave me some high-quality WAV files generated via his hardware.These were stereo, but if I check them in Audacity, both channels appear to be exactly the same.Can I consider them the same (= moving to mono), or might there be some unnoticeable differences to the human eye?

• Ranking hit after WP site migration

  - by Ben

  I migrated my site from its old domain over a month ago. I followed WMT completely, including 301 redirects from every existing URL to the new domain, and then submitting a change of address. Traffic continued as normal, but then a few days after submitting the change of address traffic plummeted to about 20-30% of what it was previously. Most of my traffic come from organic search, and I can see that for the keywords I had targeted before and performed well with and am now ranking much much lower for. In some cases for low competition keywords I've only lost a few places, for higher competition terms I have really suffered. This has started to pick up a bit (one of my keywords I have risen from 195 to 100 in the last week), but it seems to be a very slow process. How seamless is this process normally? I was under the impression that this would not affect my rankings too severely, but it has now been a month since the move and recovery seems to be very slow, if at all. Is it likely that I've missed something? The only change is that I have moved what was the home page to be more of a sub-page, and now in its place is a magazine-style home page. I understand that links to the old site will now be pointing to the latter which means that rankings for some keywords attributed to the old home page will take a hit, but even on other pages that seem to fit in exactly the same page structure as the previous site I have seen a drop in rankings. Any help would be greatly appreciated. Thanks!

• How Google Web Starter Kit serves adaptive image for mobile?

  - by 5argon

  My website weirdly (in a good way) serves smaller images when viewed on mobile. I wanted to know what cause this? As far as I know this is not the default behaviour, so I think it must be Google Web Starter Kit's doing.Here is the debug information when debugging on device. All images became 231 B size no matter how large it actually is. (On desktop debugging the size varies.) I tried using Google Web Starter Kit (https://github.com/google/web-starter-kit) recently. The tools in it are made of Ruby, Node.js, SASS and Gulp to help you 'build' website. Pre-build you can enjoy automatic reload because the Gulp script will watch all files for you. When build it will run various tools to minify HTML,CSS and compress images. According to this page https://developers.google.com/web/fundamentals/tools/build/build_site the gulp-imagemin was used. So I guess the imagemin is doing the mobile optimization for me? What kind of compression can serve automatically resized image on mobile? And why is the size 231 B? Is this related to my screen size?

• Textures quality issues with Libgdx

  - by user1876708

  I have drawn several vector objets and characters ( in Adobe Illustrator ) for my game on Android. They are all scalable at any size without any quality losses ( of course it's vector ^^ ). I have tried to simulate my gameboard directly on Illustrator just before setting my assests on libdgx to implement them in my game. I set all the objects at the good size, so that they fit perfectly on my XHDPI device I am running my test on. As you can see it works great ( for me at least ^^ ), the PNG quality is good for me, as expected ! So I have edited all my PNG at this size, set my assets on libgdx and build my game apk. And here is a screenshot of my gameboard ( don't pay attention at the differences of placing and objects, but check at the objets presents on both screenshot ). As you can see, I have a loss of my PNG quality in the game. It can be seen clealry on the hedgehog PNG, but also ( but not as obvious ) on the mushroom ( check at the outline ) and the hole PNG. If you really pay attention, on every objects, you can see pixels that are not visible on my first screenshot. And I just can't figure out why this is happening Oo If you have any ideas, you are very welcome ! Thanks. PS : You can check more clearly the 2 gameboard on this two links ( look at them at 100%, display at high resolution ) : Good quality link, from Illustrator Poor quality link, from the game Second phase of tests : We display an object ( the hedgehog ) on our main menu screen to see how it looks like. The things is that it looks like he is suppose to, which means, high quality with no pixels. The hedgehog PNG is coming from an atlas : layer.addActor(hedgehog); No loss of quality with this method So we think the problem is comming from the method we are using to display it on our gameboard : blocks[9][3] = new Block(TextureUtils.hedgehog, new Vector2(9, 3)); the block is getting the size from the vector we are associating to it, but we have a loss of quality with this method.

• Is there a Content Management System that allows multiple & independent blogs to be running on one domain?

  - by Ron

  Hello Webmasters, I am a Wordpress fan, and I'm now building a new site and I'm not sure which CMS can achieve what I'm trying to do. I am building a food blog network for a bunch of cities in the US, and I want to my city pages to be independently running blogs themselves. So basically... Home Page - Its own blog with its own users, talking about Food in general Dallas Page (child of home page) - Its own blog with its own users Chicago Page ..... so on and so forth. The web layout and design will be all the same, but just trying to achieve 25~50 independent blogs on one domain. How can I achieve this? I'm hoping that I don't have to install Wordpress into as many subdomains that I create... Thank you for your help in advance. -RP

• Ubuntu installation does not recognize drive partitioning

  - by Woltan

  I have a 1TB drive and installed Windows 7 on a 128GB partition. When I now try to install Ubuntu 11.04 it does not recognize the Windows partition but offers the complete 1TB drive to install Ubuntu on instead. It displays: However, in the Ubuntu Disk Utility the Windows partitions are recognized. What do I need to do in order for Ubuntu to recognize the Windows 7 partition and install Ubuntu as a dual boot?

• When is meta description still relevant?

  - by Jeff Atwood

  I received this bit of advice about the meta description tag recently: Meta descriptions are used by Google probably 80% of the time for the snippet. They don’t help with rankings but you should probably use them. You could just auto generate them from the first part of the question. The description tag exists in the header, like so: <meta name="Description" content="A brief summary of the content on the page."> I'm not sure why we would need this field, as Google seems perfectly capable of showing the relevant search terms in context in the search result pages, like so (I searched for c# list performance): In other words, where would a meta description summary improve these results? We want the page to show context around the actual search hits, not a random summary we inserted! Google Webmaster Central has this advice: For some sites, like news media sources, generating an accurate and unique description for each page is easy: since each article is hand-written, it takes minimal effort to also add a one-sentence description. For larger database-driven sites, like product aggregators, hand-written descriptions are more difficult. In the latter case, though, programmatic generation of the descriptions can be appropriate and is encouraged -- just make sure that your descriptions are not "spammy." Good descriptions are human-readable and diverse, as we talked about in the first point above. The page-specific data we mentioned in the second point is a good candidate for programmatic generation. I'm struggling to think of any scenario when I would want the Google-generated summary, that is, actual context from the page for the search terms, to be replaced by a hard-coded meta description summary of the question itself.

• Why does 12.04 upgrade abort with out of space error when I have lots of it?

  - by Kristian Thomsen

  When upgrading Ubuntu from 11.10 to 12.04 I discovered an unexpected problem. The upgrade was stopped because there wasn't enough free space for the installation. I managed to free some space and do the upgrade but now a prompt appears after logging in saying I'm out of space. This prompt asks me if I want to examine the problem. The "Disk Usage Analyser" is opened. In the top it says: Total filesystem capacity: 47.0 GB (used: 13.5 GB available: 33.4 GB) Folder -- Usage -- Size / -- 100% -- 12.5 GB usr -- 44.8 % -- 5.6 GB home -- 30.3 % -- 3.8 GB lib -- 13.0 % -- 1.6 GB var -- 9.1 % -- 1.1 GB boot 2.5 % 309.5 GB and a lot of small contributors like: etc, opt, sbin, bin etc. I do not really understand this problem since the analyser in the top says that I have 33.4 GB left in this file system. What can I do to make Ubuntu use the remaining space? Running df -i in the terminal gives: Filesystem Inodes IUsed IFree IUse% Mounted on /dev/sda7 610800 576874 33926 95% / udev 213451 563 212888 1% /dev tmpfs 218524 486 218038 1% /run none 218524 3 218521 1% /run/lock none 218524 7 218517 1% /run/shm /dev/sda8 2264752 16371 2248381 1% /home The output of df -h Filesystem Size Used Avail Use% Mounted on /dev/sda7 9,3G 7,8G 1,1G 88% / udev 993M 4,0K 993M 1% /dev tmpfs 401M 884K 400M 1% /run none 5,0M 0 5,0M 0% /run/lock none 1003M 152K 1002M 1% /run/shm /dev/sda8 35G 4,0G 29G 13% /home /dev/sda2 101G 64G 37G 64% /media/A2C8E28BC8E25CD3 Running sudo fdisk -l gives Disk /dev/sda: 160.0 GB, 160041885696 bytes 255 heads, 63 sectors/track, 19457 cylinders, total 312581808 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000080 Device Boot Start End Blocks Id System /dev/sda1 63 96389 48163+ de Dell Utility /dev/sda2 * 98304 210434488 105168092+ 7 HPFS/NTFS/exFAT /dev/sda3 210436094 312576704 51070305+ f W95 Ext'd (LBA) /dev/sda5 306279288 312576704 3148708+ dd Unknown /dev/sda6 210436096 214341631 1952768 82 Linux swap / Solaris /dev/sda7 214343680 233873407 9764864 83 Linux /dev/sda8 233875456 306278399 36201472 83 Linux Partition table entries are not in disk order

• Javascript Implementation Patterns for Server-side MVC Websites

  - by tmo256

  I'm looking for information on common patterns for initializing and executing Javascript page by page in a "traditional" server-side MVC website architecture. A few months ago, my development team began, but abandoned, a major re-architecture of our company's primary web app, including a full front-end redesign. In the process, there was some debate about the architecture of the Javascript in the current version of the site, and whether it fit into a clear, modern design pattern. Now I've returned to the process of overhauling the front end of this and several other MVC websites (Ruby on Rails and MVC.net) to implement a responsive framework (Bootstrap), and in the process will again need to review then revamp and update a lot of Javascript. These web applications are NOT single-page Javascript applications (in fact, we are ripping out a lot of Ajax) or designed to require a Javascript MVC pattern; these apps are basically brochure, catalog and administrative sites that follow a server-side MVC pattern. The vast majority of the Javascript required is behavioral, pre-built plugins (JQuery and Bootstrap, et al) that execute on specific DOM nodes. I'm going to give a very brief (as brief as I can be) run-down of the current architecture only in order to illustrate the scope and type of paradigm I'm talking about. Hopefully, it will help you understand the nature of the patterns I'm looking for, but I'm not looking for commentary on the specifics of this code. What I've done in the past is relatively straight-forward and easy to maintain, but, as mentioned above, some of the other developers don't like the current architecture. Currently, on document ready, I execute whatever global Javascript needs to occur on every page, and then call a page-specific init function to initialize node-specific functionality, retrieving the init method from a JS object. On each page load, something like this will happen: $(document).ready(function(){ $('header').menuAction(); App.pages.executePage('home','show'); //dynamic from framework request object }); And the main App javascript is like App = { usefulGlobalVar: 0, pages: { executePage: function(action, controller) { // if exists, App.pages[action][controller].init() }, home: { show: { init: function() { $('#tabs').tabs(); //et. al }, normalizeName: function() { // dom-specific utility function that // doesn't require a full-blown component/class/module } }, edit: ... }, user_profile: ... } } Any common features and functionality requiring modularization or compotentizing is done as needed with prototyping. For common implementation of plugins, I often extend JQuery, so I can easily initialize a plugin with the same options throughout the site. For example, $('[data-tabs]').myTabs() with this code in a utility javascript file: (function($) { $.fn.myTabs = function() { this.tabs( { //...common options }); }; }) Pointers to articles, books or other discussions would be most welcome. Again, I am looking for a site-wide implementation pattern, NOT a JS MVC framework or general how-tos on creating JS classes or components. Thanks for your help!

• Best video codec for filmed powerpoint presentation

  - by rslite

  I have some presentations that are filmed. The audio is the presenter and the video is all the Powerpoint slides (size 1024x768, video codec H264, audio codec AAC). I would like to reduce their final file size since a 1 hour presentation is about 800 MB. Most of it is the video part which as I said is mostly powerpoint slides that don't change much over a matter of several seconds. Which codec would be better suited to encode this images and reduce the size of the end file?

• Scale a game object to Bounds

  - by Spikeh

  I'm trying to scale a lot of dynamically created game objects in Unity3D to the bounds of a sphere collider, based on the size of their current mesh. Each object has a different scale and mesh size. Some are bigger than the AABB of the collider, and some are smaller. Here's the script I've written so far: private void ScaleToCollider(GameObject objectToScale, SphereCollider sphere) { var currentScale = objectToScale.transform.localScale; var currentSize = objectToScale.GetMeshHierarchyBounds().size; var targetSize = (sphere.radius * 2); var newScale = new Vector3 { x = targetSize * currentScale.x / currentSize.x, y = targetSize * currentScale.y / currentSize.y, z = targetSize * currentScale.z / currentSize.z }; Debug.Log("{0} Current scale: {1}, targetSize: {2}, currentSize: {3}, newScale: {4}, currentScale.x: {5}, currentSize.x: {6}", objectToScale.name, currentScale, targetSize, currentSize, newScale, currentScale.x, currentSize.x); //DoorDevice_meshBase Current scale: (0.1, 4.0, 3.0), targetSize: 5, currentSize: (2.9, 4.0, 1.1), newScale: (0.2, 5.0, 13.4), currentScale.x: 0.125, currentSize.x: 2.869114 //RedControlPanelForAirlock_meshBase Current scale: (1.0, 1.0, 1.0), targetSize: 5, currentSize: (0.0, 0.3, 0.2), newScale: (147.1, 16.7, 25.0), currentScale.x: 1, currentSize.x: 0.03400017 objectToScale.transform.localScale = newScale; } And the supporting extension method: public static Bounds GetMeshHierarchyBounds(this GameObject go) { var bounds = new Bounds(); // Not used, but a struct needs to be instantiated if (go.renderer != null) { bounds = go.renderer.bounds; // Make sure the parent is included Debug.Log("Found parent bounds: " + bounds); //bounds.Encapsulate(go.renderer.bounds); } foreach (var c in go.GetComponentsInChildren<MeshRenderer>()) { Debug.Log("Found {0} bounds are {1}", c.name, c.bounds); if (bounds.size == Vector3.zero) { bounds = c.bounds; } else { bounds.Encapsulate(c.bounds); } } return bounds; } After the re-scale, there doesn't seem to be any consistency to the results - some objects with completely uniform scales (x,y,z) seem to resize correctly, but others don't :| Its one of those things I've been trying to fix for so long I've lost all grasp on any of the logic :| Any help would be appreciated!

• VLC Media Server

  - by Josh

  We are using VLC on ubuntu, and trying to set up a streaming media server. We have the http interface working fine from remote computers, and we can also see the video playing as text if we don't screen VLC. Our problem is the output streaming. When we use the main VLC page you get when you goto the servers IP it does not save the output MRL (refreshing page it will go away, even after clicking save.) We tried to VLM page and it appears to work fine from the http page (it buffers, plays, timers go up when not paused, etc.) However, we still cannot connect remotely with a VLC client. The output parameters do save properly on the VLM page. We are noobs when it comes to this. Does anyone have a very to the point procedure of getting a file X to play and stream on ubuntu using VLC assuming VLC is installed?

• Are there any guidelines for laying out screen "real estate?"

  - by Corey

  I'm wondering if there is any information about creating a decent page layout so that your website will appeal to users of all resolutions. For example, the optimal width for pages. It seems like on my resolution, most websites have their content centered and covers about 80% of the page, which is easy on the eyes. Or maybe the height of the website's logo/header -- some sites I stumble upon have a huge logo with links or navigation under it, making it so that I need to scroll down to see the actual content, like articles or images (these sites don't keep me for very long). I understand that every user is different and may have browser extensions, page zoom or may be running some ancient system that displays in 640x480. I'm not looking for a "best" solution, but rather, some guidelines about designing to accommodate different resolutions. Basically, how can I make sure that I don't design a page where a paragraph might display in several easy-to-read lines on my resolution, but it turns into a single line on a 1920x1080 resolution and makes it hard for the user to follow?

• Technique to have screen independent grid based puzzle with sprite animation

  - by Yan Cheng CHEOK

  Hello all, let's say I have a fixed size grid puzzle game (8 x 10). I will be using sprites animation, when the "pieces" in the puzzle is moving from one grid to another grid. I was wondering, what is the technique to have this game being implemented as screen resolution independent. Here is what I plan to do. 1) The data structure coordinate will be represented using double, with 1.0 as max value. // Puzzle grid of 8 x 10 Environment { double width = 0.8; double height = 1.0; } // Location of Sprite at coordinate (1, 1) Sprite { double posX = 0.1; double posY = 0.1; double width = 0.1; double height = 0.1; } // scale = PYSICAL_SCREEN_SIZE drawBitmap ( sprite_image, sprite_image_rect, new Rect(sprite.posX * Scale, sprite.posY * Scale, (sprite.posX + sprite.width) * Scale, (sprite.posY + sprite.Height) * Scale), paint ); 2) A large size sprite image will be used (128x128). As sprite image shall look fine if we scale from large size down to small size, but not vice versa. Besides the above mentioned technique, is there any other consideration I had missed out?

• Creating GPT partitions on EFI raw disk using diskpart

  - by kafka

  I've got a raw, blank GPT disk for use in a UEFI system. I need to create the partitions on it using diskpart. The only tutorial I've found so far is for diskpart.efi, which I believe is slightly different from the command-line diskpart. MS guide to GPT partitions with diskpart.efi Also the guide says to create a MSR of 32MB, but for a disk= 16GB I know it needs to be 128MB. I'm happy doing it with diskpart, just want to be sure I understand the fundamentals. I'm planning on installing, in this order: ESP partition, size 102 MB (create partition esp size=102) MSR partition, size 128 MB (create partition msr size=128) data partition, the remaining space (approx 460GB) Is this the correct thing to do, or is there anything I'm missing?
