• Core debugger enhancements in VS2010

  Since my team offers "parallel debugging", we refer to the team delivering all the other debugging features as the "core debugger" team. They have published a video of new VS2010 debugger features that I encourage you to watch to find out about enhancements with DataTips, breakpoints, dump debugging (inc. IL interpreter) and Threads window.The raw list of features with short description is also here. Comments about this post welcome at the original blog.

• Black screen on latest Nvidia Cards when starting LightDM/Ubuntu

  - by Luis Alvarado

  Today I installed an Nvidia GT440 on my computer, changing the one that existed there, an Nvidia 9500GT. After changing it I started getting a problem where the screen just went black when loading the lightdm login screen (Where I punt my user and password). The thing is, if I disconnect the VGA cable and connect it again I get to see the lightdm greeter and everything works perfect. The problem is that I have to connect/disconnect every time I reboot the PC. I tried installing the 285.xx drivers. Same problem. I removed the Nvidia drivers installed with Jockey, rebooted, same problem. I install the current 280.xx again, same problem. After all that I installed a fresh install of Ubuntu, selected to install the Nvidia drivers while installing it from the livecd. After booting the same problem appeared. Dmesg does not say anything wrong about it. Same goes for the log from Jockey. What else should I check or what to do to solve it. Just to clarify, this does not happen BEFORE the lightdm greeter appears. Am guessing before the actual use of the video card with X starts with all the 2D/3D stuff that is used in ligthdm and unity. I can use any tty and even see the Ubuntu logo when starting. UPDATE: When I open a game in fullscreen the problem appears again. I have to unplug the monitor cable and plug it back in to see the game. Then when I quit the game I have to do it again to see the desktop. UPDATE 2: Today I bought a HDMI cable, connected the video card to the TV am testing it with and it actually did log in correctly without any black screen but it shows the resolution a little over the actual size of the screen. So I see only half of the launcher since the left side of it is hidden outside of the real resolution and the top bar is beyond the resolution. So the black screen is related to the VGA connection.

• What should I do to scale out an high-traffic website?

  - by makerofthings7

  What Best Practices should be undertaken for a Website that needs to "scale out" to handle capacity? This is especially relevant now that people are considering the cloud, but may be missing out on the fundamentals. I'm interested in hearing about anything you consider a best practice from development-level tasks, to infrastructure, to management. Use your best judgement when posting multiple answers, since it may make sense to post them separately for voting purposes. (hint: you'll likely get more reputation points for many small answers than one large answer)

• What makes games responsive to user input?

  - by zaftcoAgeiha

  Many games have been praised for its responsive gameplay, where each user action input correspond to a quick and precise character movement (eg: super meat boy, shank...) What makes those games responsive? and what prevents other games from achieving the same? How much of it is due to the game framework used to queue mouse/keyboard events and render/update the game and how much is attributed to better coding?

• check when a page was first seen by google

  - by sam

  Is there a way to see when a page was first published, by checking when it was first cahced by google (obviously its not 100% fool proof because there is a couple of days delay in some cases but it will give you a good idea.) The only other way i could think of checking it published date is if the page / post had a publicly viable time stamp on it, but in the case im looking for it, it dosnt have a publicly visible time stamp.

• How to determine the source of a request in a distributed service system?

  - by Kabumbus

  Map/Reduce is a great concept for sorting large quantities of data at once. What to do if you have small parts of data and you need to reduce it all the time? Simple example - choosing a service for request. Imagine we have 10 services. Each provides services host with sets of request headers and post/get arguments. Each service declares it has 30 unique keys - 10 per set. service A: name id ... Now imagine we have a distributed services host. We have 200 machines with 10 services on each. Each service has 30 unique keys in there sets. but now to find to which service to map the incoming request we make our services post unique values that map to that sets. We can have up to or more than 10 000 such values sets on each machine per each service. service A machine 1 name = Sam id = 13245 ... service A machine 1 name = Ben id = 33232 ... ... service A machine 100 name = Ron id = 777888 ... So we get 200 * 10 * 30 * 30 * 10 000 == 18 000 000 000 and we get 500 requests per second on our gateway each containing 45 items 15 of which are just noise. And our task is to find a service for request (at least a machine it is running on). On all machines all over cluster for same services we have same rules. We can first select to which service came our request via rules filter 10 * 30. and we will have 200 * 30 * 10 000 == 60 000 000. So... 60 mil is definitely a problem... I hope to get on idea of mapping 30 * 10 000 onto some artificial neural network alike Perceptron that outputs 1 if 30 words (some hashes from words) from the request are correct or if less than Perceptron should return 0. And I’ll send each such Perceptron for each service from each machine to gateway. So I would have a map Perceptron <-> machine for each service. Can any one tall me if my Perceptron idea is at least “sane”? Or normal people do it some other way? Or if there are better ANNs for such purposes?

  - by me

  Author: Peter Reiser - Social Business Evangelist, Oracle WebCenter  Solution SummaryAzul Linhas Aéreas Brasileiras (Azul Brazilian Airlines) is the third-largest airline in Brazil serving  42 destinations with a fleet of 49 aircraft and employs 4,500 crew members. The company wanted to offer an innovative site with a simple purchasing process for customers to search for and buy tickets and for the company’s marketing team to more effectively conduct its campaigns. To this end, Azul implemented Oracle WebCenter Sites, succeeding in gathering all of the site’s key information onto a single platform. Azul can now complete the Web site content updating process—which used to take approximately 48 hours—in less than five minutes. Company OverviewAzul Linhas Aéreas Brasileiras (Azul Brazilian Airlines) has established itself as the third-largest airline in Brazil, based on a business model that combines low prices with a high level of service. Azul serves 42 destinations with a fleet of 49 aircraft. It operates 350 daily flights with a team of 4,500 crew members. Last year, the company transported 15 million passengers, achieving a 10% share of the Brazilian market, according to the Agência Nacional de Aviação Civil (ANAC, or the National Civil Aviation Agency).

• Alfa AWUS036H USB wireless adapter not recognized

  - by GFiasco

  The Alfa AWUS036H USB wireless adapter will not be recognized by my netbook (Ubuntu 14.04, Asus X201E). As I understand it, the drivers should already be built in to this version of Linux, but I tried a make/make install of the latest Realtek drivers (as mentioned on How do I install drivers for the Alfa AWUS036H USB wireless adapter?) and it didn't work. I then followed the advice of this thread (ALFA AWUS036NH driver) and did a make/make install of the most up-to-date backport of the drivers, but that didn't work. At this point I tried a series of commands from this thread (http://ubuntuforums.org/showthread.php?t=2187780) in an attempt to identify the problem, but at no point could I get the laptop to ever recognize the USB adapter. I have also troubleshot the USB cable itself, tried both the USB 2.0 and 3.0 ports on the laptop, have never received an error message regarding a need to update the firmware, and have seemingly successfully installed all manner of variation of Realtek drivers which were supposed to make the adapter work. (I also tried to delete/clean up after each install, in the hope I wasn't making things worse.) Not sure what I should do next. Please let me know if I need to post any more information. Thanks very much for your help. EDIT: Before inserting Alpha USB adapter: :~$ lsusb Bus 002 Device 002: ID 8087:0024 Intel Corp.

• What's the problem with Scala's XML literals?

  - by Oak

  In this post, Martin (the language's head honcho) writes: [XML literals] Seemed a great idea at the time, now it sticks out like a sore thumb. I believe with the new string interpolation scheme we will be able to put all of XML processing in the libraries, which should be a big win. Being interested in language design myself, I'm wondering: Why does he write that it was a mistake to incorporate XML literals into the language? What is the controversy regarding this feature?
