  • Why does Ubuntu gets stuck on the loading screen?

    - by mohit
    I've been experiencing many problem lately since I fresh installed Ubuntu 12.04 LTS on my SONY VAIO VPCEH with Windows 7 previously installed. Sometimes when I try to boot Ubuntu, it gets stuck at loading screen. There seems to be some problem with driver (as far I can judge). Following is the log generated, when I press Esc during the boot (before the problem occurs): ... * Stopping System V initialization compatibility [ok] * Starting System V runlevel compatibility [ok] * Starting crash report submission daemon [ok] * Starting automatic crash report generation [ok] ... ... * Starting LightDM Display Manager [ok] Nothing works after that, no Esc, etc, except restart. Also I've observed the following: Inactivity of Hard-drive (Led doesn't glows). Flashing, or blinking, of Caps-lock and Scroll-lock On restart, Ubuntu seem to load successfully. However, the loading screen has somewhat basic graphics. This problem started after I installed Additional drivers: NVIDIA accelerated graphics driver Also, most of the times Ubuntu loads without any problem. However, it is annoying to restart everytime it fails. So my question is: Why this happens and what is the solution?

  • What does your Lisp workflow look like?

    - by Duncan Bayne
    I'm learning Lisp at the moment, coming from a language progression that is Locomotive BASIC - Z80 Assembler - Pascal - C - Perl - C# - Ruby. My approach is to simultaneously: write a simple web-scraper using SBCL, QuickLisp, closure-html, and drakma watch the SICP lectures I think this is working well; I'm developing good 'Lisp goggles', in that I can now read Lisp reasonably easily. I'm also getting a feel for how the Lisp ecosystem works, e.g. Quicklisp for dependencies. What I'm really missing, though, is a sense of how a seasoned Lisper actually works. When I'm coding for .NET, I have Visual Studio set up with ReSharper and VisualSVN. I write tests, I implement, I refactor, I commit. Then when I'm done enough of that to complete a story, I write some AUATs. Then I kick off a Release build on TeamCity to push the new functionality out to the customer for testing & hopefully approval. If it's an app that needs an installer, I use either WiX or InnoSetup, obviously building the installer through the CI system. So, my question is: as an experienced Lisper, what does your workflow look like? Do you work mostly in the REPL, or in the editor? How do you do unit tests? Continuous integration? Packaging & deployment? When you sit down at your desk, steaming mug of coffee to one side and a framed photo of John McCarthy to the other, what is it that you do? Currently, I feel like I am getting to grips with Lisp coding, but not Lisp development ...

  • What a web developer can learn [closed]

    - by knoxxs
    There are many things to learn in web development. You can easily find what are the most important thing that you need to learn if you want to be a webmaster. Answer to questions about how to become a web developer or a webmaster only contained limited items that someone need to master. (Some eg - a, b ) But the problem is that these resources are not complete. When I started learning web development i follow the same steps. But after learning the basic development I didn't know that I have learnt nothing, there are many more things to learn. I realized this by following blogs , Q&A sites. When I first downloaded the HTNL% Boilerplate, the issue that they have covered, some of them I haven't even heard about. I want you to just suggest what are the possible things, issues that someone can learn and why to learn. I know the answer is follow blogs and do your work you will learn with time, but with these platforms I could get some benefit out of other experiences. This question is not how to become a webmaster, but answer to this may also cover that too.

  • Is this possible?

    - by PythonNewbie2
    Hello, I'm exploring some technologies and JSP with JSF 2.0 and Primefaces seems really cool. I'm new to all of these, but I'm a fast learner. I wondering if I can create the web app I want withh JSP/JSF/Primefaces or should I be looking to different technologies? If I should, which ones do you recommend? Here's a basic description of the app: Users log in with their username and password (maybe I can somehow incorporate google OPENID)? With a really nice UI, they will be presented a large list of questions specific to a certain category, for example, JSP. When they click on any of these questions, a little input opens up below it to allow the user to put in a link. If the link they enter has the same question on that webpage the URL points to, they will be awarded one point. This question then disappears and gets added to a different page that has a list of all correctly linked questions. On the right side of the screen, there will be a leaderboard with the usernames of the people with the top ten points. Is this possible with JSP/JSF/Primefaces, or should I be looking elsewhere for a different web technology? The idea is relatively simple - to be able to compile links to external websites for specific questions. I know I can build the UI easily with Primefaces. What I'm not sure is if JSP/JSF gives the ability to parse HTML at a certain URL to see if it contains words. I can do this with python easily by using urllib. Any help would be appreciated!!! What would be more helpful than a "Yes" or "No" answer would be links to where I can see sample code of external HTML parsing. Your input is truly appreciated! Thanks!

  • Transaction classification. Artificial intelligence

    - by Alex
    For a project, I have to classify a list of banking transactions based on their description. Supose I have 2 categories: health and entertainment. Initially, the transactions will have basic information: date and time, ammount and a description given by the user. For example: Transaction 1: 09/17/2012 12:23:02 pm - 45.32$ - "medicine payments" Transaction 2: 09/18/2012 1:56:54 pm - 8.99$ - "movie ticket" Transaction 3: 09/18/2012 7:46:37 pm - 299.45$ - "dentist appointment" Transaction 4: 09/19/2012 6:50:17 am - 45.32$ - "videogame shopping" The idea is to use that description to classify the transaction. 1 and 3 would go to "health" category while 2 and 4 would go to "entertainment". I want to use the google prediction API to do this. In reality, I have 7 different categories, and for each one, a lot of key words related to that category. I would use some for training and some for testing. Is this even possible? I mean, to determine the category given a few words? Plus, the number of words is not necesarally the same on every transaction. Thanks for any help or guidance! Very appreciated Possible solution: https://developers.google.com/prediction/docs/hello_world?hl=es#theproblem

  • Web Sites All Start When Debugging a Web Site - Visual Studio 2010

    - by Daniel Lackey
    I wanted to blog about this because it was an annoyance to me and I couldn't figure out why for quite some time. Have you ever tried debugging one web application in your solution but when you do, all other web sites in your solution build and then start up their respective Visual Studio Development Server? It's not a major problem, but it adds time to waiting for what you are actually trying to debug to start up. After digging through Visual Studio 2010 settings, I finally found the option to turn it off. It is called Always Start When Debugging and is located in the Properties pane for the web project (click on the project .proj file in Visual Studio IDE). This is set to True by default each time you create a new Web Application project. Setting this to false will solve your problems. You will need to set this to false for all web applications in your solution as shown below: In addition, you can set properties on which port the development server uses each time it debugs. This is helpful if you want the port to stay the same for testing purposes. In contrast, you can set it to use a dynamic port each time so if you have a co-worker that is debugging it on a different session on the same server, you won't run into any problems with using the same port. The machine won't allow you to debug two sessions on the same port. Pretty basic stuff but it seemed like a really quirky setting to me.

  • Why does glGetString returns a NULL string

    - by snape
    I am trying my hands at GLFW library. I have written a basic program to get OpenGL renderer and vendor string. Here is the code #include <GL/glew.h> #include <GL/glfw.h> #include <cstdio> #include <cstdlib> #include <string> using namespace std; void shutDown(int returnCode) { printf("There was an error in running the code with error %d\n",returnCode); GLenum res = glGetError(); const GLubyte *errString = gluErrorString(res); printf("Error is %s\n", errString); glfwTerminate(); exit(returnCode); } int main() { // start GL context and O/S window using GLFW helper library if (glfwInit() != GL_TRUE) shutDown(1); if (glfwOpenWindow(0, 0, 0, 0, 0, 0, 0, 0, GLFW_WINDOW) != GL_TRUE) shutDown(2); // start GLEW extension handler glewInit(); // get version info const GLubyte* renderer = glGetString (GL_RENDERER); // get renderer string const GLubyte* version = glGetString (GL_VERSION); // version as a string printf("Renderer: %s\n", renderer); printf("OpenGL version supported %s\n", version); // close GL context and any other GLFW resources glfwTerminate(); return 0; } I googled this error and found out that we have to initialize the OpenGL context before calling glGetString(). Although I have initialized OpenGL context using glfwInit() but still the function returns a NULL string. Any ideas? Edit I have updated the code with error checking mechanisms. This code on running outputs the following There was an error in running the code with error 2 Error is no error

  • How to fix bad Collada produced by FBX?

    - by David
    I tried to use the FBX SDK (2011.3.1) to load FBX files and save them as Collada files in order to be able to import FBX files in Panda3D. Unfortunately the resulting Collada files are not usable for several reasons, among them: There's a Maya specific extra technique diffuse <diffuse> <texture texture="Map__2-image" texcoord="CHANNEL0"> <extra> <technique profile="MAYA"> <wrapU sid="wrapU0">TRUE</wrapU> <wrapV sid="wrapV0">TRUE</wrapV> <blend_mode>ADD</blend_mode> </technique> </extra> </texture> </diffuse> It assigns a texcoord channel name that isn't referenced anywhere else in the file (in the previous code sample, no geometry uses "CHANNEL0"...) Every polygon is exported twice, a first time with a basic material (only diffuse color, specular color, etc.) and a second time with a textured material -- this doubles the number of polygons of each model without any valuable reason Anyway, the resulting Collada file cannot be opened correctly either with OpenCOLLADA or Panda3D's "dae2egg". Anyone has any experience on how to "fix" it and make it understandable by common and well-reputed Collada importers such as OpenCOLLADA?

  • Building a Redundant / Distrubuted Application

    - by MattW
    This is more of a "point me in the right direction" question. I (and my team of 3) have built a hosted web app that queues and routes customer chat requests to available customer service agents (It does other things as well, but this is enough background to illustrate the issue). The basic dev architecture today is: a single page ajax web UI (ASP.NET MVC) with floating chat windows (think Gmail) a backend Windows service to queue and route the chat requests this service also logs the chats, calculates service levels, etc a Comet server product that routes data between the web frontend and the backend Windows service this also helps us detect which Agents are still connected (online) And our hardware architecture today is: 2 servers to host the web UI portion of the application a load balancer to route requests to the 2 different web app servers a third server to host the SQL Server DB and the backend Windows service responsible for queuing / delivering chats So as it stands today, one of the web app servers could go down and we would be ok. However, if something would happen to the SQL Server / Windows Service server we would be boned. My question - how can I make this backend Windows service logic be able to be spread across multiple machines (distributed)? The Windows service is written to accept requests from the Comet server, check for available Agents, and route the chat to those agents. How can I make this more distributed? How can I make it so that I can distribute the work of the backend Windows service can be spread across multiple machines for redundancy and uptime purposes? Will I need to re-write it with distributed computing in mind? I should also note that I am hosting all of this on Rackspace Cloud instances - so maybe it is something I should be less concerned about? Thanks in advance for any help!

  • Problem Installing Xubuntu 12.04 Audio-Video codecs

    - by Seib
    I used Crouton to install Xubuntu 12.04.4 LTS with the XFCE environment on my HP Chromebook 11. I've gotten it all fully installed and everything; the only thing I'm doing now is the basic setup things, like adding codecs and other things like LibreOffice, VLC, Firefox, Ubuntu Software Center, etc. This information I got from 2 sources: http://www.efytimes.com/e1/fullnews.asp?edid=137269 http://www.binarytides.com/better-xubuntu-14-04/ . I'm currently on the same step at both URLs, which is #6 on Link 1 and #8 on Link 2. Per the articles, which both said the same thing, I typed in sudo apt-get install xubuntu-restricted-extras libavcodec-extra and it didn't do anything. It just kept on saying the same thing: Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package libavcodec-extra I've spend the last hour or so scouring the internet for a solution, for a hint even at what is going on. I don't want to do a clean reinstall, for two reasons: 1) it's takes like 1.5h just to get the croot fully installed, and 2) everything but this out of what I've done so far (up to #6 at Link 1 & up to #8 at Link 2) works except the audio. I've already installed flash, so YouTube works fine. It's just I can't hear any audio. Please help? Thanks in advance. I appreciate all the great help I've been getting from AskUbuntu lately. You all are great.

  • Good Laptop .NET Developer VM Setup

    - by Steve Brouillard
    I was torn between putting this question on this site or SuperUsers. I've tried to do a good bit of searching on this, and while I find plenty of info on why to go with a VM or not, there isn't much practical advise on HOW to best set things up. Here's what I currently HAVE: HP EliteBook 1540, quad-core, 8GB memory, 500GB 7200 RPM HD, eSATA port. Descent machine. Should work just fine. Windows 7 64-bit Host OS. This also acts as my day-to-day basic stuff (email, Word Docs, etc...) OS. VMWare Desktop Windows 7 64-bit Guest OS with all my .NET dev tools, frameworks, etc loaded on it. It's configured to use 2 cores and up to 6GB of memory. I figure that the dev env will need more than email, word, etc... So, this seemed like a good option to me, but I find with the VM running, things tend to slow down all around on both the host and guest OS. Memory and CPU utilization don't seem to be an issue, but I/O does. I tried running the VM on an external eSATA drive, figuring that the extra channel might pick up the slack. Things only got worse (could be my eSATA enclosure). So, for all of that I have basically two questions in one. Has anyone used this sort of setup and are there any gotchas either around the VMWare configuration or anything else I may have missed here that you can point me to? Is there another option that might work better? For example, I've considered trying a lighter weight Host OS and run both of my environments as VMs? I tried this with Server 2008 Hyper-V, but I lose too much laptop functionality going this route, so I never completed setup. I'm not averse to Linux as a host OS, though I'm no Linux expert. If I'm missing any critical info, feel free to ask. Thanks in advance for your help. Steve

  • Squid 3 and Internet Explorer 11 with authentication

    - by StBlade
    Need some help. My college has up until now been running Squid 3 on Ubuntu 12.02 and now 14.04 successfully. That was till recently. Our WSUS server is dishing out updates to all our workstations of which Internet Explorer 11 is one of them. Now all of a sudden users do not need to authenticate via the squid proxy to be able to use the internet. This makes it rather difficult as I also use SARG to generate usage logs for all users each day. All our workstations also have Chrome on them, and Chrome authenticates fine via the Squid proxy. Doing a couple of Googles, I ran into and article, where someone made mention that Microsoft has deprecated digest and basic authentication from IE 11. Reason was given that Office 2013 was giving problems as it was not giving the popup screen for authentication when Office tries to download templates from the internet. I have run into this problem, but by setting those sites to not authenticate via squid fixed the problem. Has anyone else run into something similiar? Would changing to NTLM or Kereberos be a solution?

  • how do I write a functional spec quickly and efficiently

    - by giddy
    So I just read some fabulous articles by Joel on specs here. (Was written in 2000!!) I read all 4 parts, but Im looking for some methodical approaches to writing my specs. Im the only lonely dev, working on this fairly complicated app (or family of apps) for a very well known finance company. I've never made something this serious, I started out writing something like a bad spec, an overview of some sorts, and it has wasted a LOT of my time. Ive also made 3 mockup-kinda-thingies for my client so I have a good understanding of what they want. Also released a preview (a throw away working app with the most basic workflow), and Ive only written and tested some of the very core/base systems. I think the mistake Ive been making so far is not writing a detailed spec, so Im getting to it now. So the whole thing comprises of An MVC website (for admins & data viewing) 2 Silverlight modules (For 2 specific tasks) 1 Desktop Application Im totally short on time, resources and need to get this done quick, also, need to make sure these guys read it up equally quick and painlessly. So how do I go about it, Im looking for any tips, any real world stuff, how do you guys usually do it? Do you make a mock screenie of every dialog/form/page? Im thinking of making a dummy asp.net web forms project, then filling in html files in folders and making it look like my mvc url structure. Then having a section in the spec for the website and write up a page for every URL Ive got with a screenie. For my win forms app, Ive made somewhat of a demo Win Form project, would I then put in a dialog or stucture everything as I would in the real app and then screen shot it?

  • RAM caching causes severe performance drops

    - by B T
    I have read plenty of threads on memory caching and the standard response of "large cache is good, it shouldn't effect performance", "the kernel knows best". I have recently upgraded from 12.04 to 12.10 and changed from VirtualBox to VMware Workstation and the performance differences are severe (I suspect it is because of the latter). When I am running my virtual machine the system load monitor graph shows less than 50% memory usage generally. System load indicator is showing me that the rest of my RAM is used in the cache all the time. Plain and simple this is the comparison: BEFORE Cache was very sparingly used, pretty much none of my memory usage was the cache Swappiness was 0 (caused my memory to be used first, then swap only if needed) Performance was quite good and logical RAM was used fully first, caching was minimal. I could run enough software to utilize my full 4GB of RAM without any performance degradation whatsoever Swap space was then used as needed which was obviously slower (I am on a HDD) but was still usable when the current program was loaded into memory AFTER Cache is used to fill the full 4GB as soon as my virtual machine is run Swappiness is 0 (same behaviour as before but cache uses full memory straight away) Performance is terrible and unusable while running Ubuntu software Basic things like changing windows takes 2 minutes + Changing screens happens frame by frame over sometimes up to 5 minutes Cannot run an IDE and VM like I could with ease before So basically, any suggestions on how to take my performance back to how it was before while keeping my current setup? My suspicion is VMWare is the problem, but how do I see what is tied to the use of the cache? Surely there is a way to control this behaviour in software as polished as VMware? Thanks EDIT: Could also be important to note that the behaviour differs depending on whether VMware is open or closed. If VMware is open, then the ram will lock at like 50% and 50% cache and go into the complete lock up mentioned above. Contrastingly, if VMware is closed (after being open), then the RAM will continue to rise as it needs / cache will stay as the complete remaining memory and there is no noticeable performance degradation.

  • Reading Open Source Projects

    - by Hossein
    About my programming knowledge: I have basic knowledge of programming. Have never worked in a team project. Have done, only, a couple of small solo projects. Problem: Consider a typical open source project. We want to know about the project, so that we can contribute, test it, just out of curiosity, etc. The documentations do not describe the code architecture, usually, so RTFM(!) wouldn't apply here. They usually tend to describe how to use the software, not how it is designed. Mailing Lists in big projects are very crowded. Tens of e-mails are send in just an hour. also, following the mailing list to know the project is like understanding a film when you have arrived late, when half of the film is gone or even worse. Obviously, the code is not like a novel. So, you can't start from downloading the source code and just "start from the first page and so on"! Question: How should one understand open source project? What are the steps to do in an open source project, to understand how the whole thing works and get into speed with the "under the hood"?

  • Transform coordinates from 3d to 2d without matrix or built in methods

    - by Thomas
    Not to long ago i started to create a small 3D engine in javascript to combine this with an html5 canvas. One of the issues I run into is how can you transform 3d to 2d coords. Since I cannot use matrices or built in transformation methods I need another way. I've tried implementing the next explanation + pseudo code: http://freespace.virgin.net/hugo.elias/routines/3d_to_2d.htm Unfortunately no luck there. I've replace all the input variables with data from my own camera and object classes. I have the following data: An object with a rotation, position vector and an array of 4 3d coords (its just a plane) a camera with a position and rotation vector the viewport - a square 600 x 600 surface. The example uses a zoom factor which I've set as 1 Most hits on google use either matrix calculations or don't implement camera rotation. Basic transformation should be like this: screen.x = x / z * zoom screen.y = y / z * zoom Can anyone point me in the right direction or explain to me howto achieve this? edit: Thanks for all your posts, I haven't been able to apply all this to my project yet but I hope to do this soon.

  • Language parsing to find important words

    - by Matt Huggins
    I'm looking for some input and theory on how to approach a lexical topic. Let's say I have a collection of strings, which may just be one sentence or potentially multiple sentences. I'd like to parse these strings to and rip out the most important words, perhaps with a score that denotes how likely the word is to be important. Let's look at a few examples of what I mean. Example #1: "I really want a Keurig, but I can't afford one!" This is a very basic example, just one sentence. As a human, I can easily see that "Keurig" is the most important word here. Also, "afford" is relatively important, though it's clearly not the primary point of the sentence. The word "I" appears twice, but it is not important at all since it doesn't really tell us any information. I might expect to see a hash of word/scores something like this: "Keurig" => 0.9 "afford" => 0.4 "want" => 0.2 "really" => 0.1 etc... Example #2: "Just had one of the best swimming practices of my life. Hopefully I can maintain my times come the competition. If only I had remembered to take of my non-waterproof watch." This example has multiple sentences, so there will be more important words throughout. Without repeating the point exercise from example #1, I would probably expect to see two or three really important words come out of this: "swimming" (or "swimming practice"), "competition", & "watch" (or "waterproof watch" or "non-waterproof watch" depending on how the hyphen is handled). Given a couple examples like this, how would you go about doing something similar? Are there any existing (open source) libraries or algorithms in programming that already do this?

  • Java Desktop Application For Network users

    - by Motasem Abu Aker
    I'm developing a desktop application using Java. My application will run in a network environment where multiple users will access the same database through the application. There will be basic CRUD opreations (Insert, Update, Delete, & select), which means there will be chances of deadlock, or two users trying to update the same record at same time. I'm using the following Java Swing for Clients (MVC). MySQL Server for database (InnODB). Java Web start. Now, MySQL is centralized on the network, and all of the clients connect to it. The Application for ERP Purpose. I searched the internet to find a very good solution to ensure data integrity & to make sure that when updating one record from one client, other clients are aware of it. I read about Socket-server-client & RESTful web services. I don't want to go web application & don't want to use any extra libraries. So how can I handle this scenario: If User A updates a record: Is there a way to update User B's screen with the new value? If user A starts updating a record, how can I prevent other users from attempting to update the same record?

  • Looking for 2D Cross platform suggestions based on requirements specified

    - by MannyG
    I am an intermediate developer with minor experience on enterprise mobile applications for iphone, android and blackberry looking to build my first ever mobile game. I did a google search for some game dev forums and this popped up so I thought I would try posting here as I lack luck elsewhere. If you have ever heard of the game for the iphone and android platform entitled avatar fight then you will have an idea of the graphic capabilities I require. Basically the battles which are automated one sprite attacking another doing cool animations but all in 2d. My buddy and I have two motivations, one is to jump into mobile Dev as my experience is limited as is his so we would like some trending knowledge (html5 would be nice to learn) . The other is to make some money on the side, don't expect much but polishing the game and putting our all will hopefully reward us a bit. We have looked into corona engine, however a lot of people are saying it is limited in the graphics department, we are open to learning new languages like lua, c++, python etc. Others we have looked at include phonegap, rhomobile, unity, and the list goes on. I really have no idea what the pros and cons of these are but for a basic battle sequence and some mini games we want to chose the right one. Some more things that we will be doing include things like card games, side scrolling flying object based games, maybe fishing stuff. We want to start small with these minigames and work our way up to the idea we would like to implement in the future. We only want to work in 2D. So with these requirements please help me chose a platform to work on (cross platform is what we are ideally leaning towards). Please feel free to throw in some pieces of advice you may have for newbie game developers like myself too. Thank you for reading!

  • Self-referencing anonymous closures: is JavaScript incomplete?

    - by Tom Auger
    Does the fact that anonymous self-referencing function closures are so prevelant in JavaScript suggest that JavaScript is an incomplete specification? We see so much of this: (function () { /* do cool stuff */ })(); and I suppose everything is a matter of taste, but does this not look like a kludge, when all you want is a private namespace? Couldn't JavaScript implement packages and proper classes? Compare to ActionScript 3, also based on EMACScript, where you get package com.tomauger { import bar; class Foo { public function Foo(){ // etc... } public function show(){ // show stuff } public function hide(){ // hide stuff } // etc... } } Contrast to the convolutions we perform in JavaScript (this, from the jQuery plugin authoring documentation): (function( $ ){ var methods = { init : function( options ) { // THIS }, show : function( ) { // IS }, hide : function( ) { // GOOD }, update : function( content ) { // !!! } }; $.fn.tooltip = function( method ) { // Method calling logic if ( methods[method] ) { return methods[ method ].apply( this, Array.prototype.slice.call( arguments, 1 )); } else if ( typeof method === 'object' || ! method ) { return methods.init.apply( this, arguments ); } else { $.error( 'Method ' + method + ' does not exist on jQuery.tooltip' ); } }; })( jQuery ); I appreciate that this question could easily degenerate into a rant about preferences and programming styles, but I'm actually very curious to hear how you seasoned programmers feel about this and whether it feels natural, like learning different idiosyncrasies of a new language, or kludgy, like a workaround to some basic programming language components that are just not implemented?

  • Review: Data Modeling 101

    I just recently read “Data Modeling 101”by Scott W. Ambler where he gave an overview of fundamental data modeling skills. I think this article was excellent for anyone who was just starting to learn or refresh their skills in regards to the modeling of data.  Scott defines data modeling as the act of exploring data oriented structures.  He goes on to explain about how data models are actually used by defining three different types of models. Types of Data Models Conceptual Data Model  Logical Data Model (LDMs) Physical Data Model(PDMs) He further expands on modeling by exploring common data modeling notations because there are no industry standards for the practice of data modeling. Scott then defines how to actually model data by expanding on entities, attributes, identities, and relationships which are the basic building blocks of data models. In addition he discusses the value of normalization for redundancy and demoralization for performance. Finally, he discuss ways in which Developers and DBAs can become better data modelers through the use of practice, and seeking guidance from more experienced data modelers.

  • Bookmark Sentry Scans Your Chrome Bookmarks File For Bad Links and Dupes

    - by Jason Fitzpatrick
    Chrome: Bookmark Sentry, a free Chrome extension, takes the hard work out of checking your bookmark file for bad links and duplicates. Install it, forget about it, and get scheduled reports on the state of your bookmarks file. It’s that simple. Once you install the extension, open the options to toggle some basic settings to your liking (like the frequency of the scan, how long you want it to wait for a response, and whether you want it to look for bad links and/or duplicates). Once it finishes scanning you’ll get a report indicating the status of the links (why they are marked as missing or duped) and the ability to selectively or mass delete them. The only caveat we’d share is that it will tell you links behind any sort of security are unavailable. If you bookmark pages that you use for work, behind your corporate firewall for example, if the scanner runs when you’re not authenticated then it won’t be able to reach them. Other than that, it works like a charm. Bookmark Sentry is free, Google Chrome only.
