• Throttle and overheating on Dell XPS Studio 1645

  - by Ross

  I realise there is an older thread on the very subject but that seems to be pretty dead. I just got a Dell Studio XPS 1645 laptop and the fan noise and overheating is pretty ridiculous. This is actually a well known problem with the laptop that is apparently solved with the combination of a BIOS update and the purchase of their 130w charger. I plan on buying this charger as soon as possible, however I've noticed that since installing Ubuntu the fan noise has became more permanent and the overheating is quite a bit worse too. I've had to turn it off twice to let it cool down for an hour or so because it starts seriously affecting the performance. It makes watching things, listening to music or leaving the laptop on while I sleep a real pain. If anyone has some new information on this issue or could help out in anyway at all I'd be very grateful. Thanks.

• Asus 1215n GPU driver/s don't give me a "full" OS experience

  - by AFD

  I'm use to not having specific drivers from a manufacture on my laptop when running a Linux OS and that has always been fine - there's been adequate FOSS drivers for my needs and it hasn't ruined any of my OS experience. When I bought an Asus 1215n one of the upsides to the hardware seemed to be the switchable GPU that could give lots of performance or lots more battery life and would switch on-the-fly... with Windows of course. Seems that the Nvidia driver are crap and people advise not installing them. I have some sort of workaround for vga_switcharoo (?) and the on-the-fly nature of the GPUs has turned in to a manual one :( The worst bit though (aside from shorter battery life) is the web experience with HTML5. If I visit Mozilla's Web O'Wonder site I'm told I don't have WebGL working due to driver issues. This really blows - is it possible that proprietary drivers can now ruin my web experience too?!

• Public Cloud, co-location and managed services ... what is the cloud?

  - by llaszews

  Recently I have had conversation with a number of people that are selling and implementing 'cloud' solutions. I put cloud in quotes as implementations like co-location (aka co-lo) and managed services (sometimes referred to as 'your mess for less') have become popular options for companies moving to the cloud. These are obviously not pure public cloud offerings and probably more of hybrid cloud implementations as the infrastructure (PasS and IaaS)is dedicated to a specific customer. This eliminates the security, multi-tenancy, performance and other concerns that companies have regarding public cloud. Are co-location and managed services cloud to you? Are they something your company is considering when you think about cloud ?

• How to manage two video cards on a laptop (ATI and Intel)?

  - by Marc-François Cochaux-Laberge

  I have a laptop with two video cards. One ATI and on integrated Intel. On Windows, I can choose which video card I want to use. For example, I use the Intel card for normal use and for gaming, I switch to my ATI card for better performance, but a shorter battery life. In Ubuntu 10.10, only the Intel driver is installed, the ATI driver for my card doesn't work at all and there's heat coming out of my computer all the time, like when I'm playing video games on Windows. I think both cards are active, but only the Intel one is usefull. How can I solve this by making sure Ubuntu is aware of the two video cards and by disabling my ATI. Or may be I am all wrong about this?

• Displaying thumbnails in google search results for flash games?

  - by serg

  Some sites are somehow displaying video preview thumbnails for pages that contain flash games in google search results. For example search for: site:www.thorgaming.com game I see this only on small sites which makes me believe google is not very happy about it. How do they do it and is it ok with google? I assume they are submitting thumbnails through video sitemaps, but I can't find any information about using them with flash games. I also run a few such sites through rich snipped testing tool and it didn't detect any microdata tags on a page.

• Empathy 3.6.0 requires reauthorisation to Windows Live on every reboot

  - by Allu2

  I've been testing Ubuntu 12.10 beta2 and the only problem I've faced has been that with Windows Live Messenger(a.k.a MSN) After I have added Windows Live in the online-accounts in system settings, empathy works fine and connects to Windows Live Messenger with no problems until I reboot my system. After rebooting and logging in, when empathy connects to services it shows me message "Windows Live account requires authorisation" next to it is a button that takes me back to online-accounts where i can see the authorized Windows Live. So far the only way to get MSN work again has been to remove the Windows Live authorisation and add it again, which makes it work till the next time i close my computer. How could i make empathy to remember the authorisation to Windows Live

• ANTLRWorks 2: Early Access Preview 10

  - by Geertjan

  I took a quick look at how the ANTLRWorks 2 project is getting on... and discovered that today, March 23, the new early access preview 10 has been released: http://www.antlr.org/wiki/display/ANTLR4/1.+Overview Downloaded it immediately and was impressed when browsing through the Java.g file that I also found on the Antlr site: (Click to enlarge the image above.) On the page above, the following enhancements are listed: Add tooltips for rule references Finally fixed the navigator update bug Major improvements to code completion Fix legacy mode Many performance and stability updates I've blogged before about how the developers on the above project consider their code completion to be "scary fast". Some discussions have taken place about how code developed by the ANTLRWorks team could be contributed to the NetBeans project, since NetBeans IDE and ANTLRWorks 2 are both based on the NetBeans Platform.

• Update drivers for TL-WN851ND

  - by Tony_GPR

  Today I bought a new PCI wireless card, TP-Link WN851ND, with Atheros AR9227 chipset. It has 2 antennas and is compatible with Wifi N so I thought it would improve the quality of the signal. But after install it on my computer the result is the opposite to expected. It doesn't connect to my network, while my old Wifi BG card connect without problems, I created an access point from my smartphone to try the card, and work, but is very slow loading pages. In Windows 7 works perfectly, so I think the problem is the driver. I have Ubuntu 12.04 LTS with kernel 3.2.0.31, is there a way to update the driver or I can apply a patch to improve the performance of the card? Otherwise, anyone know if there is a work in progress to improve compatibility with this chipset, or is it better to change the card and buy one with better driver compatibility. And finally, which wireless N compatible chipsets have good support under Linux/Ubuntu?

• Online iPad 1&2 emulators give different results compared to the real thing

  - by Systembolaget

  I'm designing a centered website (jQuery Isotope). Thre sandbox is here. I have used some online iPad 1&2 emulators to test how the site is viewed on these devices. Then, I managed to get hold of the real thing. Result: on real iPads, the site is centered and the layout adjusts automatically as expected. In online iPad emulators, the site is not quite centered and additional Isotope elements are squeezed in. Of course, I trust the real thing more than online emulators, but why is this happening? To me, it feels like website testing with online emulators is not so reliable after all? If this question is wrong here, please move it or tell me where it should go. SO is about programming, this question isn't. Thanks!

• Design a Distributed System

  - by Bonton255

  I am preparing for an interview on Distributed Systems. I have gone through a lot of text and understand the basics of the area. However, I need some examples of discussions on designing a distributed system given a scenario. For example, if I were to design a distributed system to calculate if a number N is primary or not, what will the be design of the system, what will be the impact of network latency, CPU performance, node failure, addition of nodes, time synchronization etc. If you guys could present your in-depth thoughts on this example, or point me to some similar discussion, that would be really helpful.

• Setting coding priorities

  - by dotnetdev

  Hi, In the dev shops I've worked in, nobody has ever mentioned "coding priorities". I read this in a book or site somewhere, and sets the expectation of what priority should be first in the code. In places where this is not specified, what should the first priority be? It may sound simple to say "do what the business need requires", but that could be at the expense of performance/maintainability. Many people say maintainability first, regardless, some say fulfill the need regardless. I am a young developer, so I am probably missing the point somewhere. Of course, programming is engineering and tough because you can never have the perfect solution. Thanks

• How to keep a team well-trained?

  - by PierrOz

  Hi dear fellows, I'm currently mentoring a small team of 4 junior dev in small software company. They are very smart and often achieve their tasks with a high-quality job but I'm sure they still can do better - actually I have exactly the same feeling for myself :) -. Besides some of them are more "junior" than other. So I would like to find of a funny way to improve their CS skills (design, coding, testing, algorithmic...) in addition to the experience they acquire in their daily work. For instance, I was thinking of setting up weekly sessions, not longer than 2 hours, where we could get together to work on challenging CS exercises. A bit like a coding dojo. I'm sure the team would enjoy that but is it really a good idea? Would it be efficient in a professional context? They already spend all their week to code so how should I organize that in order for them to get some benefits? Any feedback welcome !

• Penny auction concept and how the timer works

  - by madi

  I am creating a penny auction site using PHP yii framework. The main consideration of the system is to update the database records of all active auctions (max 15 auctions) with the current ticker timer. I am seeking for advice on how i should design the system where every auction item will have a its own countdown timer stored in the database and when someone bids the auction item, the counter resets to 2 min. Every users who are connected to the system should see the same countdown timer for that particular auction. I am little confused on how i should design the system. Will there be a performance issue when there are frequent updates to the database (Mysql) where 15 active auctions are updated every seconds, the countdown timer decreases by a second in the database table for the particular auction. Schema Sample for auction_lots: Auction_id,startdatetime,counter_timer,status I am seeking for advice on how I should design this. Please help. Thank you!

• How to crawl a webPage with dynamic content added by javascript

  - by blunderboy

  I guess there is a news that Google bots have the capability to understand our javascript code. It means this is possible to fully crawl a webpage which has lazy loading feature enabled. I am using Apache Nutch to crawl websites but I don't think it has the capability to fetch the URLs being injected in HTML page by javascript when the page is scrolled down. I see a lot of websites doing lazy loading for performance issue. So Can somebody please explain me how can i crawl the data which comes in HTML page on lazy load. (On scrolling the page down).
