• VGA monitor won't detect on NVIDIA Quadro NVS 4200M

  - by tanmayk

  I am on a Dell Latitude E6420 and just installed 12.04. When I plug in my external monitor's VGA cable, the laptop doesn't detect any new monitor. Here's the output of my lspci: 00:00.0 Host bridge: Intel Corporation 2nd Generation Core Processor Family DRAM Controller (rev 09) 00:01.0 PCI bridge: Intel Corporation Xeon E3-1200/2nd Generation Core Processor Family PCI Express Root Port (rev 09) 00:16.0 Communication controller: Intel Corporation 6 Series/C200 Series Chipset Family MEI Controller #1 (rev 04) 00:16.3 Serial controller: Intel Corporation 6 Series/C200 Series Chipset Family KT Controller (rev 04) 00:19.0 Ethernet controller: Intel Corporation 82579LM Gigabit Network Connection (rev 04) 00:1a.0 USB controller: Intel Corporation 6 Series/C200 Series Chipset Family USB Enhanced Host Controller #2 (rev 04) 00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 04) 00:1c.0 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 1 (rev b4) 00:1c.1 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 2 (rev b4) 00:1c.2 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 3 (rev b4) 00:1c.3 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 4 (rev b4) 00:1c.5 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 6 (rev b4) 00:1d.0 USB controller: Intel Corporation 6 Series/C200 Series Chipset Family USB Enhanced Host Controller #1 (rev 04) 00:1f.0 ISA bridge: Intel Corporation QM67 Express Chipset Family LPC Controller (rev 04) 00:1f.2 RAID bus controller: Intel Corporation 82801 Mobile SATA Controller [RAID mode] (rev 04) 00:1f.3 SMBus: Intel Corporation 6 Series/C200 Series Chipset Family SMBus Controller (rev 04) 01:00.0 VGA compatible controller: NVIDIA Corporation GF119 [Quadro NVS 4200M] (rev a1) 01:00.1 Audio device: NVIDIA Corporation HDMI Audio stub (rev a1) 03:00.0 Network controller: Intel Corporation Centrino Advanced-N 6205 (rev 34) 0b:00.0 SD Host controller: O2 Micro, Inc.

• Is it wise to ask about design decisions made on a product during an interview?

  - by Desolate Planet

  I've been thinking about interview questions lately and I've been reflecting on bad interview experiences I've had in the past. One of particular note is where I had asked the interviewer why the team chose to use Spring over EJB3 in their product. The interviewer pretty much tore my face off, yelling "Because Spring is not the be all and end all of Java software development, do you want this job or not?". In response to this, I told him that this probably wasn't the job for me and I walked out the interview. He told me at the start of the interview that they had high stuff turnover, the product had gone from Modula 3 to Perl to Java then after asking him a technical question, he went in flames. It seemed obvious to me that he was toxic to the company with that kind of attitude. Question: Is it a good idea to probe on architectural choices taken in an interview? If not, why? From my own point of view, an interview is a two-way process. If the interviewers are testing me on my technical skills, I've got every right to ask them the same questions to 1) Figure out what their mindset and attitudes towards developing software solutions are and 2) To figure out if there are in line with how I would approach problems of that kind. It's very possible that the interviewer who got angry was a bad interviewer and forgot that an interview is a two-way process. If I was asked this, I would have simply said something along the lines of wanting to leverage the container more, but I certainly wouldn't have tried to put him in a state of meek capitulation. The interviewer in question was the lead developer in the team.

• Suitability of ground fog using layered alpha quads?

  - by Nick Wiggill

  A layered approach would use a series of massive alpha-textured quads arranged parallel to the ground, intersecting all intervening terrain geometry, to provide the illusion of ground fog quite effectively from high up, looking down, and somewhat less effectively when inside the fog and looking toward the horizon (see image below). Alternatively, a shader-heavy approach would instead calculate density as function of view distance into the ground fog substrate, and output the fragment value based on that. Without having to performance-test each approach myself, I would like first to hear others' experiences (not speculation!) on what sort of performance impact the layered alpha texture approach is likely to have. I ask specifically due to the oft-cited impacts of overdraw (not sure how fill-rate bound your average desktop system is). A list of games using this approach, particularly older games, would be immensely useful: if this was viable on pre DX9/OpenGL2 hardware, it is likely to work fine for me. One big question is in regards to this sort of effect: (Image credit goes to Lume of lume.com) Notice how the vertical fog gradation is continuous / smooth. OTOH, using textured quad layers, I can only assume that layers would be mighty obvious when walking through them -- the more sparse they were, the more obvious this would be. This is in contrast to where fog planes are aligned to face the player every frame, where this coarseness would be much less obvious.

• Lenovo ThinkPad L520 slows down when AC power adapter is plugged in

  - by Aamir

  I have a new laptop Lenovo ThinkPad L520 (7859-5BG) Core i5-2520M(2.5GHz) with 4GB RAM. Having installed Ubuntu 11.10 32-bit, while browsing with Chrome on GNOME classic (no effects), I noticed 173% CPU usage by chrome browser process, and the system slowly got very very slow, Now, at this stage as I removed the power adapter, the system suddenly got faster (and stopped the lagging behavior) and CPU usage drops down to 48% !! Observation 1: I was browsing through chrome when my system seemed to be seriously lagging, so I killed chrome to see if it gets any faster. But there remained no difference. Notice that CPU usage was a bit strange here. It showed no high activity, but as soon as I would click on applications in gnome panel, it would shoot CPU usage to 70, or 80 or 90 or 143% etc. depending on how quickly i clicked back and forth. At this instance I removed by AC adapter of my laptop, and suddenly system got fine. So i again clicked on gnome panel, and noticed that it now took only 7% or 12% or 13% at max, with same kind of clicks in application menu. Observation 2: At the other times, with AC adapter plugged in, top indicates four instances of chromium taking 90%, 60%, 47% and 2% (for example), and then once I take out the AC adapter same processes take lesser CPU all of a sudden Intermediate conclusions: What does this indicate ? I cannot figure out any "other" process in "top" that is suddenly being triggered, its the same process that hogs up my CPU once AC power is plugged in ! NOTE: the problem is now CONFIRMED, as i can repeat that when I have power adapter plugged in ! Can anyone tell me what exactly does this indicate ? What is wrong, is it some bug with power management or what ?

• How to View Netflix Watch Instantly in XBMC

  - by Justin Garrison

  Netflix streaming isn’t just a feature that is nice to have, for many people it is a must have for any video streaming software. Unfortunately it has been missing from XBMC for various reasons, until today. In order to get Netflix Watch Instantly working in XBMC you just need to have XBMC 10.0+ installed on Windows or OS X. Because of a lack of Silverlight support, this currently does not work on XBMC Live, Linux, or iOS devices (iPhone, iPad, AppleTV).

• TDD - Outside In vs Inside Out

  - by Songo

  What is the difference between building an application Outside In vs building it Inside Out using TDD? These are the books I read about TDD and unit testing: Test Driven Development: By Example Test-Driven Development: A Practical Guide: A Practical Guide Real-World Solutions for Developing High-Quality PHP Frameworks and Applications Test-Driven Development in Microsoft .NET xUnit Test Patterns: Refactoring Test Code The Art of Unit Testing: With Examples in .Net Growing Object-Oriented Software, Guided by Tests---This one was really hard to understand since JAVA isn't my primary language :) Almost all of them explained TDD basics and unit testing in general, but with little mention of the different ways the application can be constructed. Another thing I noticed is that most of these books (if not all) ignore the design phase when writing the application. They focus more on writing the test cases quickly and letting the design emerge by itself. However, I came across a paragraph in xUnit Test Patterns that discussed the ways people approach TDD. There are 2 schools out there Outside In vs Inside Out. Sadly the book doesn't elaborate more on this point. I wish to know what is the main difference between these 2 cases. When should I use each one of them? To a TDD beginner which one is easier to grasp? What is the drawbacks of each method? Is there any materials out there that discuss this topic specifically?

• Thinktecture IdentityServer v1.0

  - by Your DisplayName here!

  Yeah – it is finally done. I just uploaded the v1 bits to Codeplex and the documentation to our server. Here’s the official blurb… Thinktecture IdentityServer is an open source security token service based on Microsoft .NET, ASP.NET MVC, WCF and WIF. High level features Multiple protocols support (WS-Trust, WS-Federation, OAuth2, WRAP, JSNotify, HTTP GET) Multiple token support (SAML 1.1/2.0, SWT) Out of the box integration with ASP.NET membership, roles and profile Support for username/password and client certificates authentication Support for WS-Federation metadata Support for WS-Trust identity delegation Extensibility points to customize configuration and user management handling Disclaimer I did thorough testing of all features of IdentityServer - but keep in mind that this is an open source project and I am the only architect, developer and tester on the team. IdentityServer also lacks many of the enterprise-level features like configuration services, proxy support, operations integration etc. I only recommend using IdentityServer if you also understand how it works (to be able to support it). I am offering consulting to help you with customization and lock down - contact me. Download. Documentation. Up next is v1 of the Azure version. Have fun!

• How do I handle having too many links on a webpage because of my menu

  - by RandomBen

  I am developing a website that has a drop-down menu at the top of it. The Menu has around 100 links in it that are repeated on every page. Every page also has some number of links below the Menu that may or may not be in the menu itself. My issue is that Google says they generally don't like pages with more than 100 links on them. Is there any way to change the links on the menu so that they no longer "count" towards my max of 100 links? It seems like there should be an easy way to do this but their really doesn't seem to be. the rel=nofollow still counts towards the number of links on the page at least according to Google, so what other options do I have? I looked into where the 100 comes from and I found that it used to be here: http://www.google.com/support/webmasters/bin/answer.py?hl=en&answer=35769#2 but that is no longer the case. I found a more definitive and frankly muddier answer here: http://www.seomoz.org/blog/questions-answers-with-googles-spam-guru from Matt Cutts from 2007. Long story short, in 2007 they still felt 100 links was a good number but they stated you could go far beyond that. In fact, they said that pages with high PageRank could have 2-300. It did sound like having many links could reduce the PageRank of the page with all of the links or possibly all of the items linked to. Also, I know IIS7's SEO 1.0 toolkit suggests that pages should have no more than 250 links.

• B.S.in Computer Science, weak eyes => career change

  - by Prometheus

  So I am going to earn B.S. in Computer Science soon. I like computers. I like programming. The problem is that my eyes are very weak. Depending on their condition, I can only put in about 6 hours in front of computer a day. If I push myself, I have trouble even keeping my eyes open because of soreness/pain, consequently headaches. My eyes do not have medical conditions. I was just born with weak eyes. I tried many different approaches to work around this problem - better monitor, breaks every 10 minutes, supplements... I even memorized a lot of shortcuts to reduce my time on computers! But I am finally giving up. I do not think I can be a programmer for the rest of my life. I was the top of my class in high school because all works were paper-based, I did average in college due to the nature of my eyes and the difficulty of the material. So what do you recommend I do? Or, Is there a career that is similar to programming but requires interacting with computers less?

• Why does TDD work?

  - by CesarGon

  Test-driven development (TDD) is big these days. I often see it recommended as a solution for a wide range of problems here in Programmers SE and other venues. I wonder why it works. From an engineering point of view, it puzzles me for two reasons: The "write test + refactor till pass" approach looks incredibly anti-engineering. If civil engineers used that approach for bridge construction, or car designers for their cars, for example, they would be reshaping their bridges or cars at very high cost, and the result would be a patched-up mess with no well thought-out architecture. The "refactor till pass" guideline is often taken as a mandate to forget architectural design and do whatever is necessary to comply with the test; in other words, the test, rather than the user, sets the requirement. In this situation, how can we guarantee good "ilities" in the outcomes, i.e. a final result that is not only correct but also extensible, robust, easy to use, reliable, safe, secure, etc.? This is what architecture usually does. Testing cannot guarantee that a system works; it can only show that it doesn't. In other words, testing may show you that a system contains defects if it fails a test, but a system that passes all tests is not safer than a system that fails them. Test coverage, test quality and other factors are crucial here. The false safe feelings that an "all green" outcomes produces to many people has been reported in civil and aerospace industries as extremely dangerous, because it may be interepreted as "the system is fine", when it really means "the system is as good as our testing strategy". Often, the testing strategy is not checked. Or, who tests the tests? I would like to see answers containing reasons why TDD in software engineering is a good practice, and why the issues that I have explained above are not relevant (or not relevant enough) in the case of software. Thank you.

• SQLAuthority News – My Evaluation of Singapore SharePoint Conference

  - by pinaldave

  Earlier this year I presented at SQLAuthority News – Presenting at South East Asia SharePoint Conference – Oct 26, 27, 2010 – Singapore. I felt very good to be presenting at Singapore as SharePoint Conference as I was the only SQL Speaker at the event. The event was filled with SharePoint enthusiasts and lots of other experts from all around the globe. The event was one of the best organized event, I attended in subcontinent. I just received my feedback score of the event. I was very much surprised and stunned. My ratting are very high as well, my demo were considered as one of the best demo of the whole event. I am not sure how much feedback I can share with community as organizer did not specify to me but I am very certain that I am allowed to share my own feedback. Speaker – 4.39 (best score 4.74, average 3.84) Contents – 4.37 (best score 4.39, average 3.65) Demo – 4.48 (best score, 4.48, average 3.61) I am very glad that all of my efforts to do presentations at SharePoint Conference are finally paid up. I was very much worried earlier if attendees will accept me or not as I am coming as speaker from foreign technology and no one knows me there. I must thank all of you for the same.

• I want to build a Virtual Machine, are there any good references?

  - by Michael Stum

  I'm looking to build a Virtual Machine as a platform independent way to run some game code (essentially scripting). The Virtual Machines that I'm aware of in games are rather old: Infocom's Z-Machine, LucasArts' SCUMM, id Software's Quake 3. As a .net Developer, I'm familiar with the CLR and looked into the CIL Instructions to get an overview of what you actually implement on a VM Level (vs. the language level). I've also dabbled a bit in 6502 Assembler during the last year. The thing is, now that I want¹ to implement one, I need to dig a bit deeper. I know that there are stack based and register based VMs, but I don't really know which one is better at what and if there are more or hybrid approaches. I need to deal with memory management, decide which low level types are part of the VM and need to understand why stuff like ldstr works the way it does. My only reference book (apart from the Z-Machine stuff) is the CLI Annotated Standard, but I wonder if there is a better, more general/fundamental lecture for VMs? Basically something like the Dragon Book, but for VMs? I'm aware of Donald Knuth's Art of Computer Programming which uses a register-based VM, but I'm not sure how applicable that series still is, especially since it's still unfinished? Clarification: The goal is to build a specialized VM. For example, Infocom's Z-Machine contains OpCodes for setting the Background Color or playing a sound. So I need to figure out how much goes into the VM as OpCodes vs. the compiler that takes a script (language TBD) and generates the bytecode from it, but for that I need to understand what I'm really doing. ¹ I know, modern technology would allow me to just interpret a high level scripting language on the fly. But where is the fun in that? :) It's also a bit hard to google because Virtual Machines is nowadays often associated with VMWare-type OS Virtualization...

• From the Tips Box: Revitalizing Ink Cartridges with a Water Infusion

  - by Jason Fitzpatrick

  If you’re convinced your ink cartridge has more ink to share than it is willing to give up, you’re right. Read on to see how How-To Geek reader Max squeezes extra life out of his cartridges with plain old water. Max wrote in with his simple solution. He wasn’t as interested in refilling his cartridges as he was in getting all the ink out of them. Here’s his detailed guide to getting nearly every drop of ink out of your high-priced ink cartridge: The ink in many brands of ink jet printer cartridges is generally water soluble. To see if your ink is water soluble, wet your finger and rub it across a page from your printer you don’t mind wasting.  If the print smears the ink is obviously water soluble. The top of the printer cartridge generally has the manufacturer’s label attached. It covers tiny holes through which the ink was injected into the cartridge during manufacture.

• Am I too young to burn out?

  - by Steve McMesse

  I feel like I have burned out, even though I am only out of college for 5 years. For the first 3 years of my career, things were going awesome. I was never anything special in school, but I felt special at my company. Looking back, I could tell that I made all the right moves: I actively tried to improve myself daily. I made a point of helping anyone I could. I made a point (and read books about) being a good team member. I had fun. After 3 years in a row as being rated as a top employee, I converted that political capital into choosing to work on an interesting, glamorous project with only 2 developers: me and a highly respected senior technical leader. I worked HARD on that project, and it came out a huge success. High in quality, low in bugs, no delays, etc. The senior tech lead got a major promotion and a GIGANTIC bonus. I got nothing. I was so disappointed that I just stopped caring. Over the last year, I have just kind of floated. During my first 4 years I felt energized after a 10 hour day. Now I can barely be bothered to work 6 hours a day. Any advice? I don't even know what I'm asking. I am just hoping smart people see this and drop me a few pieces of wisdom.

• Learning C, C++ and C#

  - by Zac

  I'm sure you guys are tired of this question but after wading through hours of similar posts and questions I've really not made any progress to my specific concerns. I was hoping you guys could shed some light on a couple of questions I have before I decide on a course of action. BACKGROUND: I'm wanting to enroll in some type of program to learn a programming language/get a certificate/degree to work in the field. I've always been interested and bought a book on VB back in high school and dabbled. Now I want to get serious after a huge hiatus. Question 1: I've read it's counter-productive to learn C first, then C++ or C# because you develop bad habits. In a lot of college courses I've looked at, learning C/C++ is mandatory to advance. Should I ever bother learning C? On a related note, I really don't understand the difference between C and C++, or C# for the matter other than it incorporates .NET (which, I understand, is a compilation of tools and libraries that make programming easier and faster). Question 2: Where did you guys learn to program? Where do you recommend? Is it possible to land a job programming being self-taught? Is my best chance an ITT tech or a regular college? I was going to enroll in a JC and go from there but I can't decide what to do. LAST question :) I heard C++ is being "ported" to .NET. True? And if so, is this going to make C++ a solid, in-demand language to learn? Thanks for looking. :)

• GIS-based data visualization and maintenance tool

  - by Dave Jarvis

  Background Looking to leverage an existing GIS system for exploring organizational data. Architecture The following figure represents a high-level overview of the system's desired features: The most basic usage would be as follows: The user visits a web site. The system presents a map (having regions, cities, and buildings). The user drills-down on the map to a particular building. The system provides a basic CRUD interface. The user can view and modify information about personnel (e.g., their assigned teams), equipment (e.g., network appliances), applications, and the building itself (e.g., contact and phone numbers). Ideally, all the components should be open-source (or otherwise free). Problem This must be a small project that needs a quick (but functional) prototype, mostly to confirm whether or not such a system would be useful in the long term. Questions What software components would you use to quickly develop a working prototype? What open-source solutions already exist, if any? Ideas Here is what I am thinking: PostGIS - Define the regions, cities, and sites Google Maps - Display an interactive, clickable map geoJSON - Protocol between PostGIS and Google Maps Seam - CRUD interface Custom Development For example, this would entail: Installation and configuration Configure SSH for remote logins Subversion (or git) PostgreSQL PostGIS Java Tomcat Seam JasperReports Enter GIS information into PostGIS Aggregate data sources into PostgreSQL database Develop starting page for map interface Develop clickable Google Maps interface Develop summary reports Develop CRUD interface using Seam for data maintenance Surely something like this already exists? Thank you!

• How should I manage persistent score in Game Center leaderboards?

  - by Omega

  Let's say that I'm developing an iOS RPG where the player gains 1 point per monster kill. The amount of monsters killed is persistent data: it is an endless adventure, and the score keeps on growing. It isn't a "session score" like Fruit Ninja, but rather a "reputation score". There are Game Center leaderboards for that score. Keep killing monsters, your score goes up, and the leaderboards are updated. My problem is that, technically, you can log out and log in using a different Game Center account, kill one monster, and the leaderboards will be updated for the new GC account. Supposing that this score is a big deal, this could be considered as cheating, because if you have a score of 2000, any of your friends who have never played the game can simply log into your iPhone, play the game, and the system will update the score for their accounts, essentially giving them 2000 points in the leaderboards for doing nothing. I have considered linking one GC account to a specific save game. It won't update your score unless you're using the linked GC account. But what if the player actually needs to change their GC account? Technically they would be forced to start a new game and link their account to that profile. How should I prevent this kind of cheat? Essentially, I don't want someone to distribute a high schore to multiple GC accounts, given the fact that the game updates the score constantly since it isn't a "session score". I do realize that it isn't quite a big deal. But I'm curious about how to avoid this.

• Addicted to the MIX Buzz

  - by Dave Campbell

  Well it's the Friday before MIX10, and I'm officially of no use to anybody. I'll be driving up to 'Vegas Sunday ... hopefully rolling in mid-late afternoon, checking in at my $31.50/night (including WiFi) Motel, and getting registered then hanging out around registration to see who is there. First organized thing to do is 9PM, so I'm open to suggestions Sunday evening... maybe we can get a gang together for dinner ?? Monday is the Keynote ... I'm addicted to the buzz in the ballroom the first day, hope to be close to the front, trying to live blog. Then straight to Ballroom A and stake out the spot I'll be in for all 3 days, and you all know why :) I've tagged 40 sessions that I 'want' to see, and there's only 12 slots... damn... if I could, I'd try the Multiplicity thing, but I'm afraid I'd get the idiot first try -- or maybe got that one already :) ... but at least I tagged them to make it easy to find after the videos are up. Stuff going on Sunday, Monday, and Tuesday night. I'm staying over for an event on Thursday, and driving back on Friday. I'm not sure how much blogging I'll be doing, but I'll try to hit some 'Cream high spots. I'm sure everyone #NotAtMIX is going to be tuned into the sessions online. I'll be wearing TShirts with WynApse.com and SilverlightCream.com printed on the back... so if you see some old curmudgeon with such a shirt, IT'S ME! I look forward to seeing all the people I only see once or twice a year, and meeting ones I haven't met yet What a week... Bring It On and Stay in the 'Light!

• 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?

• Strange Ubuntu Random Display [Video]

  - by d4v1dv00

  I had this random display issue ever since Ubuntu 11.04 and now running Ubuntu 11.10 and this problem still persist. It is very hard for me to explain, so I uploaded a video to elaborate itself. Before I convert from Windows 7, this issue never happened. The symptom is so random that I cannot reproduce or tell precisely when will this happen again. My wild guess is, should this be related to driver? Below are my detail system information: $ lspci 00:00.0 Host bridge: Intel Corporation 2nd Generation Core Processor Family DRAM Controller (rev 09) 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) 00:16.0 Communication controller: Intel Corporation 6 Series/C200 Series Chipset Family MEI Controller #1 (rev 04) 00:1a.0 USB Controller: Intel Corporation 6 Series/C200 Series Chipset Family USB Enhanced Host Controller #2 (rev 05) 00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 05) 00:1c.0 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 1 (rev b5) 00:1c.3 PCI bridge: Intel Corporation 6 Series/C200 Series Chipset Family PCI Express Root Port 4 (rev b5) 00:1d.0 USB Controller: Intel Corporation 6 Series/C200 Series Chipset Family USB Enhanced Host Controller #1 (rev 05) 00:1f.0 ISA bridge: Intel Corporation H67 Express Chipset Family LPC Controller (rev 05) 00:1f.2 SATA controller: Intel Corporation 6 Series/C200 Series Chipset Family 6 port SATA AHCI Controller (rev 05) 00:1f.3 SMBus: Intel Corporation 6 Series/C200 Series Chipset Family SMBus Controller (rev 05) 02:00.0 Ethernet controller: Broadcom Corporation NetLink BCM57788 Gigabit Ethernet PCIe (rev 01) is there any other information i need to post and how do i do that?

• probability of trouble-free upgrade

  - by intuited

  One of the problems with recommending Ubuntu to potential future users, especially those not particularly given to technical endeavours, is that there is a chance that upgrades will break their machine, and they'll have to pay or otherwise coerce some knowledgeable person into fixing them. In my limited experience of running successive versions of Ubuntu since 8-something on a couple of different laptops, this chance is quite high. I'm not sure if I'm just unlucky with the hardware that I'm using, or if it's a result of the higher-than-average number of packages I have installed, or if upgrades are just typically problematic. So I'd like to know the likelihood, for a casual user, of doing a release upgrade, for example from 10.04 to 10.10, without experiencing any regression bugs. Obviously this is dependent on the hardware that people are running. Canonical seems to be making some efforts towards collecting data on this, for example with the "I am affected by this bug" checkbox on their issue tracker, and with the laptop compatibility reports, but I've not seen anything comprehensive. I'm hoping for an objective reference here, for example a study carried out by relatively unbiased individuals. However, anecdotal evidence is probably useful too.

• BDD/TDD vs JAD?

  - by Jonathan Conway

  I've been proposing that my workplace implement Behavior-Driven-Development, by writing high-level specifications in a scenario format, and in such a way that one could imagine writing a test for it. I do know that working against testable specifications tends to increase developer productivity. And I can already think of several examples where this would be the case on our own project. However it's difficult to demonstrate the value of this to the business. This is because we already have a Joint Application Development (JAD) process in place, in which developers, management, user-experience and testers all get together to agree on a common set of requirements. So, they ask, why should developers work against the test-cases created by testers? These are for verification and are based on the higher-level specs created by the UX team, which the developers currently work off. This, they say, is sufficient for developers and there's no need to change how the specs are written. They seem to have a point. What is the actual benefit of BDD/TDD, if you already have a test-team who's test cases are fully compatible with the higher-level specs currently given to the developers?
