• Windows expand over 2 monitors in quad-monitor setup

  - by Martin

  i just installed ubuntu 11.10 with my previous hardware setup: 4 monitors and 2 identical nvidia graphic cards. draging windows around all 4 monitors works nice, but when i maximize a window it expand always over 2 screens. (2x twinview). i had an workaround for this in 11.04 but cant remember what it was... may one of you guys have quad monitors up and running with window maximizing on only one screen my xorg.conf looks like this: # nvidia-settings: X configuration file generated by nvidia-settings # nvidia-settings: version 280.13 (buildd@allspice) Thu Aug 11 20:54:45 UTC 2011 # nvidia-xconfig: X configuration file generated by nvidia-xconfig # nvidia-xconfig: version 280.13 ([email protected]) Wed Jul 27 17:15:58 PDT 2011 Section "ServerLayout" # Removed Option "Xinerama" "1" # Removed Option "Xinerama" "0" Identifier "Layout0" Screen 0 "Screen0" 0 0 Screen 1 "Screen1" 0 1080 InputDevice "Keyboard0" "CoreKeyboard" InputDevice "Mouse0" "CorePointer" Option "Xinerama" "1" EndSection Section "Files" EndSection Section "InputDevice" # generated from default Identifier "Mouse0" Driver "mouse" Option "Protocol" "auto" Option "Device" "/dev/psaux" Option "Emulate3Buttons" "no" Option "ZAxisMapping" "4 5" EndSection Section "InputDevice" # generated from default Identifier "Keyboard0" Driver "kbd" EndSection Section "Monitor" Identifier "Monitor0" VendorName "Unknown" ModelName "Samsung SMB2220N" HorizSync 31.0 - 80.0 VertRefresh 56.0 - 75.0 Option "DPMS" EndSection Section "Monitor" Identifier "Monitor1" VendorName "Unknown" ModelName "Samsung SMB2220N" HorizSync 31.0 - 80.0 VertRefresh 56.0 - 75.0 Option "DPMS" EndSection Section "Device" Identifier "Device0" Driver "nvidia" VendorName "NVIDIA Corporation" BoardName "GeForce GTX 550 Ti" BusID "PCI:2:0:0" EndSection Section "Device" Identifier "Device1" Driver "nvidia" VendorName "NVIDIA Corporation" BoardName "GeForce GTX 550 Ti" BusID "PCI:3:0:0" EndSection Section "Screen" # Removed Option "TwinView" "True" # Removed Option "MetaModes" "nvidia-auto-select, nvidia-auto-select" # Removed Option "metamodes" "CRT-0: nvidia-auto-select 1920x1080 +0+0, CRT-1: nvidia-auto-select 1920x1080 +1920+0" Identifier "Screen0" Device "Device0" Monitor "Monitor0" DefaultDepth 24 Option "TwinView" "1" Option "TwinViewXineramaInfoOrder" "CRT-0" Option "metamodes" "CRT-0: nvidia-auto-select +0+0, CRT-1: nvidia-auto-select +1920+0" SubSection "Display" Depth 24 EndSubSection EndSection Section "Screen" # Removed Option "TwinView" "True" # Removed Option "MetaModes" "nvidia-auto-select, nvidia-auto-select" # Removed Option "metamodes" "CRT-0: nvidia-auto-select 1920x1080 +0+0, CRT-1: nvidia-auto-select 1920x1080 +1920+0" Identifier "Screen1" Device "Device1" Monitor "Monitor1" DefaultDepth 24 Option "TwinView" "1" Option "TwinViewXineramaInfoOrder" "CRT-0" Option "metamodes" "CRT-0: nvidia-auto-select +0+0, CRT-1: nvidia-auto-select +1920+0" SubSection "Display" Depth 24 EndSubSection EndSection Section "Extensions" Option "Composite" "Disable" EndSection

• [MINI HOW-TO] Update Your Zune Player Software

  - by Mysticgeek

  Keeping your computer and software up to date is very important in keeping everything running smooth and secure. It’s also important to keep your geeky gadgets updated as well. Here we take a look at updating a Zune HD. Note: In this example we’re updating a Zune HD out of the box which hasn’t been updated yet. The first thing you’ll need to do if you haven’t already is download and install the latest Zune software (link below). Now plug your Zune into your computer with the included USB connection cable and give it a moment to be recognized. Next launch the Zune Desktop software and you should get the following screen. Just accept the EULA… Then the update kicks off. Make sure not to disconnect the Zune while the update takes place. The update will take a few minutes, and after it’s complete you should be good to go and can start using your Zune. To update your player in the future, go to General Settings then Player Update. Just like your computer’s hardware and software, you want to keep your other geeky gadgets updated as well. This will help the device run more smoothly, and sometimes add additional functionality.

• #altnetseattle &ndash; CQRS

  - by GeekAgilistMercenary

  This is a topic I know nothing about, and thus, may be supremely disparate notes.  Have fun translating.  : )   . . .and coolness that the session is well past capacity. Separates things form the UI and everything that needs populated is done through commands.  The domain and reports have separate storage. Events populate these stores of data, such as "sold event". What it looks like, is that the domain controls the requests by event, which would be a product order or something similar. Event sourcing is a key element of the logic. DDD (Domain Driven Design) is part of the core basis for this methodology/structure. The architecture/methodology/structure is perfect for blade style plugin hardware as needed. Good blog entry DDDD: Why I love CQRS and another Command and Query Responsibility Segregation (CQRS), more, CQRS à la Greg Young, a bit by Udi Dahan and there are more.  Google, Bing, etc are there for a reason. It appears the core underpinning architectural element of this is the break out of unique identifiable actions, or I suppose better described as events.  Those events then act upon specific pipelines such as read requests, write requests, etc.  I will be doing more research on this topic and will have something written up shortly.  At this time it seems like nothing new, just a large architectural break out of identifiable needs of the entire enterprise system.  The reporting is in one segment of the architecture, the domain is in another, hydration broken out to interfaces, and events are executed to incur events on the Reports, or what appears by the description to be events on the domain. Anyway, more to come on this later.

  - by MarkPearl

  Learning Outcomes Name different device categories Discuss the functions and structure of I/.O modules Describe the principles of Programmed I/O Describe the principles of Interrupt-driven I/O Describe the principles of DMA Discuss the evolution characteristic of I/O channels Describe different types of I/O interface Explain the principles of point-to-point and multipoint configurations Discuss the way in which a FireWire serial bus functions Discuss the principles of InfiniBand architecture External Devices An external device attaches to the computer by a link to an I/O module. The link is used to exchange control, status, and data between the I/O module and the external device. External devices can be classified into 3 categories… Human readable – e.g. video display Machine readable – e.g. magnetic disk Communications – e.g. wifi card I/O Modules An I/O module has two major functions… Interface to the processor and memory via the system bus or central switch Interface to one or more peripheral devices by tailored data links Module Functions The major functions or requirements for an I/O module fall into the following categories… Control and timing Processor communication Device communication Data buffering Error detection I/O function includes a control and timing requirement, to coordinate the flow of traffic between internal resources and external devices. Processor communication involves the following… Command decoding Data Status reporting Address recognition The I/O device must be able to perform device communication. This communication involves commands, status information, and data. An essential task of an I/O module is data buffering due to the relative slow speeds of most external devices. An I/O module is often responsible for error detection and for subsequently reporting errors to the processor. I/O Module Structure An I/O module functions to allow the processor to view a wide range of devices in a simple minded way. The I/O module may hide the details of timing, formats, and the electro mechanics of an external device so that the processor can function in terms of simple reads and write commands. An I/O channel/processor is an I/O module that takes on most of the detailed processing burden, presenting a high-level interface to the processor. There are 3 techniques are possible for I/O operations Programmed I/O Interrupt[t I/O DMA Access Programmed I/O When a processor is executing a program and encounters an instruction relating to I/O it executes that instruction by issuing a command to the appropriate I/O module. With programmed I/O, the I/O module will perform the requested action and then set the appropriate bits in the I/O status register. The I/O module takes no further actions to alert the processor. I/O Commands To execute an I/O related instruction, the processor issues an address, specifying the particular I/O module and external device, and an I/O command. There are four types of I/O commands that an I/O module may receive when it is addressed by a processor… Control – used to activate a peripheral and tell it what to do Test – Used to test various status conditions associated with an I/O module and its peripherals Read – Causes the I/O module to obtain an item of data from the peripheral and place it in an internal buffer Write – Causes the I/O module to take an item of data form the data bus and subsequently transmit that data item to the peripheral The main disadvantage of this technique is it is a time consuming process that keeps the processor busy needlessly I/O Instructions With programmed I/O there is a close correspondence between the I/O related instructions that the processor fetches from memory and the I/O commands that the processor issues to an I/O module to execute the instructions. Typically there will be many I/O devices connected through I/O modules to the system – each device is given a unique identifier or address – when the processor issues an I/O command, the command contains the address of the address of the desired device, thus each I/O module must interpret the address lines to determine if the command is for itself. When the processor, main memory and I/O share a common bus, two modes of addressing are possible… Memory mapped I/O Isolated I/O (for a detailed explanation read page 245 of book) The advantage of memory mapped I/O over isolated I/O is that it has a large repertoire of instructions that can be used, allowing more efficient programming. The disadvantage of memory mapped I/O over isolated I/O is that valuable memory address space is sued up. Interrupts driven I/O Interrupt driven I/O works as follows… The processor issues an I/O command to a module and then goes on to do some other useful work The I/O module will then interrupts the processor to request service when is is ready to exchange data with the processor The processor then executes the data transfer and then resumes its former processing Interrupt Processing The occurrence of an interrupt triggers a number of events, both in the processor hardware and in software. When an I/O device completes an I/O operations the following sequence of hardware events occurs… The device issues an interrupt signal to the processor The processor finishes execution of the current instruction before responding to the interrupt The processor tests for an interrupt – determines that there is one – and sends an acknowledgement signal to the device that issues the interrupt. The acknowledgement allows the device to remove its interrupt signal The processor now needs to prepare to transfer control to the interrupt routine. To begin, it needs to save information needed to resume the current program at the point of interrupt. The minimum information required is the status of the processor and the location of the next instruction to be executed. The processor now loads the program counter with the entry location of the interrupt-handling program that will respond to this interrupt. It also saves the values of the process registers because the Interrupt operation may modify these The interrupt handler processes the interrupt – this includes examination of status information relating to the I/O operation or other event that caused an interrupt When interrupt processing is complete, the saved register values are retrieved from the stack and restored to the registers Finally, the PSW and program counter values from the stack are restored. Design Issues Two design issues arise in implementing interrupt I/O Because there will be multiple I/O modules, how does the processor determine which device issued the interrupt? If multiple interrupts have occurred, how does the processor decide which one to process? Addressing device recognition, 4 general categories of techniques are in common use… Multiple interrupt lines Software poll Daisy chain Bus arbitration For a detailed explanation of these approaches read page 250 of the textbook. Interrupt driven I/O while more efficient than simple programmed I/O still requires the active intervention of the processor to transfer data between memory and an I/O module, and any data transfer must traverse a path through the processor. Thus is suffers from two inherent drawbacks… The I/O transfer rate is limited by the speed with which the processor can test and service a device The processor is tied up in managing an I/O transfer; a number of instructions must be executed for each I/O transfer Direct Memory Access When large volumes of data are to be moved, an efficient technique is direct memory access (DMA) DMA Function DMA involves an additional module on the system bus. The DMA module is capable of mimicking the processor and taking over control of the system from the processor. It needs to do this to transfer data to and from memory over the system bus. DMA must the bus only when the processor does not need it, or it must force the processor to suspend operation temporarily (most common – referred to as cycle stealing). When the processor wishes to read or write a block of data, it issues a command to the DMA module by sending to the DMA module the following information… Whether a read or write is requested using the read or write control line between the processor and the DMA module The address of the I/O device involved, communicated on the data lines The starting location in memory to read from or write to, communicated on the data lines and stored by the DMA module in its address register The number of words to be read or written, communicated via the data lines and stored in the data count register The processor then continues with other work, it delegates the I/O operation to the DMA module which transfers the entire block of data, one word at a time, directly to or from memory without going through the processor. When the transfer is complete, the DMA module sends an interrupt signal to the processor, this the processor is involved only at the beginning and end of the transfer. I/O Channels and Processors Characteristics of I/O Channels As one proceeds along the evolutionary path, more and more of the I/O function is performed without CPU involvement. The I/O channel represents an extension of the DMA concept. An I/O channel ahs the ability to execute I/O instructions, which gives it complete control over I/O operations. In a computer system with such devices, the CPU does not execute I/O instructions – such instructions are stored in main memory to be executed by a special purpose processor in the I/O channel itself. Two types of I/O channels are common A selector channel controls multiple high-speed devices. A multiplexor channel can handle I/O with multiple characters as fast as possible to multiple devices. The external interface: FireWire and InfiniBand Types of Interfaces One major characteristic of the interface is whether it is serial or parallel parallel interface – there are multiple lines connecting the I/O module and the peripheral, and multiple bits are transferred simultaneously serial interface – there is only one line used to transmit data, and bits must be transmitted one at a time With new generation serial interfaces, parallel interfaces are becoming less common. In either case, the I/O module must engage in a dialogue with the peripheral. In general terms the dialog may look as follows… The I/O module sends a control signal requesting permission to send data The peripheral acknowledges the request The I/O module transfers data The peripheral acknowledges receipt of data For a detailed explanation of FireWire and InfiniBand technology read page 264 – 270 of the textbook

• Wireless with WEP extremely slow on an Acer Timeline 4810T with a Centrino Wireless-N 1000

  - by noq38

  I've upgraded an Acer Timeline 4810T to Ubuntu 11.10. Everything works fine except for the darn wireless interface (network manager). I just tested the wireless interface over a non-encrypted signal and it works beautifully. The issue is definitely related to WEP. Unfortunately, some of the networks I need to connect to are WEP encrypted, therefore this is a serious issue for me that is preventing me from using Ubuntu on my laptop. This was no problem in 11.04 and prior. Is there a simple solution for this? Any suggestions? Here's more hardware information. Hopefully this helps to debug the network issue: sudo lshw -class network *-network description: Wireless interface product: Centrino Wireless-N 1000 vendor: Intel Corporation physical id: 0 bus info: pci@0000:02:00.0 logical name: wlan0 version: 00 serial: 00:1e:64:3c:5e:e0 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=iwlagn driverversion=3.0.0-13-generic-pae firmware=39.31.5.1 build 35138 latency=0 link=no multicast=yes wireless=IEEE 802.11bgn resources: irq:43 memory:d2400000-d2401fff lspci 02:00.0 Network controller: Intel Corporation Centrino Wireless-N 1000 rfkill list 0: phy0: Wireless LAN Soft blocked: no Hard blocked: no 1: acer-wireless: Wireless LAN Soft blocked: no Hard blocked: no Many thanks for your help!

• Exalogic&ndash;The One Day Installation Challenge

  - by james.bayer

  It’s a really exciting time for the extended WebLogic community as we are enjoying seeing the impressive results of Exalogic deployments.  At Oracle Open World, a lot of people I spoke with came away impressed with the raw performance.  However, Exalogic offers a lot more than just raw performance.  I had the pleasure of working with Ram Sivaram during one of the Exalogic training sessions in Santa Clara.  In this video diary, he shows the Exalogic machine arrive on the shipping dock, get unpacked, wired up, powered on, configured, and installed with a WebLogic Server cluster in just about 10 hours.  I’ve worked with customers in the past that have taken several weeks or longer to get an environment ready after the hardware arrives.  This typically involves many different specialized teams in their organization.  Mohamad Afshar just wrote a great explanation of the benefit of Engineered Systems and contrasting that to the status quo.  Being able to streamline deployment of middleware capacity will have a lot of value for customers shortening time to deployment.  Thanks for the video Ram, you’ve set a high bar, we’ll see if anyone can top your time!

• deWitters Game loop in libgdx(Android)

  - by jaysingh

  I am a beginner and I want a complete example in LibGDX for android(Fixed time game loop) how to limit the framerate to 50 or 60. Also how to mangae interpolation between game state with simple example code e.g. deWiTTERS Game Loop: @Override public void render() { float deltaTime = Gdx.graphics.getDeltaTime(); Update(deltaTime); Render(deltaTime); } libgdx comments:- There is a Gdx.graphics.setVsync() method (generic = backend-independant), but it is not present in 0.9.1, only in the Nightlies. "Relying on vsync for fixed time steps is a REALLY bad idea. It will break on almost all hardware out there. See LwjglApplicationConfiguration, there's a flag in there that let s use toggle gpu/software vsynching. Play around with it." (Mario) NOTE that none of these limit the framerate to a specific value... if you REALLY need to limit the framerate for some reason, you'll have to handle it yourself by returning from render calls if xxx ms haven't passed since the last render call. li

• Atheros wireless not working

  - by Chandru1

  I have been struggling hard since i have installed Ubuntu 10.10 but it has been difficult for me to get my wifi working. So here is what i tried. First i checked whether i have the driver using the ifconfig command and it shows the wireless lan driver as wlan0. Next, i tried the command iwlist wlan0 scanning by becoming the root which gave me the output as no scan results. Next, i visited this link https://help.ubuntu.com/community/WifiDocs/Driver/Atheros to see as to what problem my laptop may have. I do own have an ath5k chipset. And as i followed the instructions in the above link in one of the blacklist-ath_pci.conf file had this written in it. For some Atheros 5K RF MACs, the madwifi driver loads buts fails to correctly initialize the hardware, leaving it in a state from which ath5k cannot recover. To prevent this condition, stop madwifi from loading by default. Use Jockey to select one driver or the other. (Ubuntu: #315056, #323830 I am not that good at Linux but i have given it a try. I am desperate to have my wifi working and i would be glad if this community could help. ADDED: If anyone would like to know as to what drivers i am using this is the output. network description: Wireless interface product: AR2413 802.11bg NIC vendor: Atheros Communications Inc. physical id: 3 bus info: pci@0000:0a:03.0 logical name: wlan0 version: 01 serial: 00:19:7d:d3:0c:fd width: 32 bits clock: 33MHz capabilities: pm bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=ath5k driverversion=2.6.35-24-generic firmware=N/A latency=168 link=no maxlatency=28 mingnt=10 multicast=yes wireless=IEEE 802.11bg resources: irq:18 memory:d0000000-d000ffff Some more information and output as to what i have done. lsmod | grep ath ath5k 130083 0 mac80211 231541 1 ath5k ath 8153 1 ath5k cfg80211 144470 3 ath5k,mac80211,ath led_class 2633 1 ath5k

• How to re-configure graphics from Intel integrated to Intel / ATI switchable?

  - by Bucic

  There are lots of 'how to get switchable graphics to work' guides but I found none on how to configure a system for switchable graphics operation on Ubuntu from the ground up, nor explaining the current driver situation for particular computer models (integrated+discrete combinations). Example: https://help.ubuntu.com/community/HybridGraphics My system being mature and on Intel integrated card also makes things complicated. System information: Ubuntu 12.04 amd64, installed clean with system configured to use only the integrated Intel card Lenovo Thinkpad T500 Intel GMA 4500MHD / ATI Mobility Radeon HD 3650 Current situation: Mature and up-to-date system with no configuration changes to what's given above. I've made a backup image of the system (Clonezilla) so regardless of what's written below let's assume it's our starting point. If something in What I have already tried is not clear you may as well diregard it. What I have already tried: Configuring BIOS to switchable graphics and: Installing Additional Hardware drivers - returned an error. Installing proprietary amd-driver-installer-12.6-legacy-x86.x86_64.run automatically - system starts to 'low-graphics mode'. Tried fixing as per https://help.ubuntu.com/community/BinaryDriverHowto/ATI#Manually_installing_Catalyst_12.6.2C_special_case_for_Intel.2BAC8-ATI_hybrid_graphics Got lost, gave up. Please note that while configuring BIOS for integrated graphics only is pretty straightforward, configuring for switchable graphics is not.

• high performance with xen, vmware or virtualbox

  - by Marchosius

  I was wondering which is the best method to go about if I want to play win based games. I do not want to go with the dual boot method as this will cost me time to restart, login and run a os to do my work or pass the time, and some of my apps rely on win and my graphics to run. for example Daz3d, Photoshop, Flash etc. Now I read about HVM(hardware virtual machines) and then I know about the 3D virtualisation of VMware and VirtualBox. How ever the 2 later virtualise the 3D not using the full power of the GPU. So this option wont perform perfect for latest games like D3. I was wondering if anyone have experience in HVM(like xen if i am not mistaken) and tried something similar to access the full power of the GPU and successfully run newer games and other products relying on the GPU? Will be the first time setting up a HVM, no experience in this so don't know what to expect. This will help a lot as I do not want to revert back to win or as mentioned do dual boot.

• White Paper on Analysis Services Tabular Large-scale Solution #ssas #tabular

  - by Marco Russo (SQLBI)

  Since the first beta of Analysis Services 2012, I worked with many companies designing and implementing solutions based on Analysis Services Tabular. I am glad that Microsoft published a white paper about a case-study using one of these scenarios: An Analysis Services Case Study: Using Tabular Models in a Large-scale Commercial Solution. Alberto Ferrari is the author of the white paper and many people contributed to it. The final result is a very technical document based on a case study, which provides a level of detail that I don’t see often in other case studies (which are usually more marketing-oriented). This white paper has the following structure: Requirements (data model, capacity planning, client tool) Options considered (SQL Server Columnstore Indexes, SSAS Multidimensional, SSAS Tabular) Data Model optimizations (memory compression, query performance, scalability) Partitioning and Processing strategy for near real-time latency Hardware selection (NUMA analysis, Azure VM tests) Scalability tests (estimation of maximum users per node) If you are in charge of evaluating Tabular as analytical engine, or if you have to design your solution based on Tabular, this white paper is a must read. But if you just want to increase your knowledge of Analysis Services, you will find a lot of useful technical information. That said, my favorite quote of the document is the following one, funny but true: […] After several trials, the clear winner was a video gaming machine that one guy on the team used at home. That computer outperformed any available server, running twice as fast as the server-class machines we had in house. At that point, it was clear that the criteria for choosing the server would have to be expanded a bit, simply because it would have been impossible to convince the boss to build a cluster of gaming machines and trust it to serve our customers.  But, honestly, if a business has the flexibility to buy gaming machines (assuming the machines can handle capacity) – do this. Owen Graupman, inContact I want to write a longer discussion about how companies are adopting Tabular in scenarios where it is the hidden engine of a more complex solution (and not the classical “BI system”), because it is more frequent than you might expect (and has several advantages over many alternative approaches).

• SQLAuthority News – Scaling Up Your Data Warehouse with SQL Server 2008 R2

  - by pinaldave

  Data Warehouses are suppose to be containing huge amount of the data from the beginning. However, there are cases when too big is not enough. Every Data Warehouse Admin will agree that they have faced situation where they will need to scale up their data warehouse. Microsoft has released white paper discussing the same. Here is the abstract from the Microsoft Official site: SQL Server 2008 introduced many new functional and performance improvements for data warehousing, and SQL Server 2008 R2 includes all these and more. This paper discusses how to use SQL Server 2008 R2 to get great performance as your data warehouse scales up. We present lessons learned during extensive internal data warehouse testing on a 64-core HP Integrity Superdome during the development of the SQL Server 2008 release, and via production experience with large-scale SQL Server customers. Our testing indicates that many customers can expect their performance to nearly double on the same hardware they are currently using, merely by upgrading to SQL Server 2008 R2 from SQL Server 2005 or earlier, and compressing their fact tables. We cover techniques to improve manageability and performance at high-scale, encompassing data loading (extract, transform, load), query processing, partitioning, index maintenance, indexed view (aggregate) management, and backup and restore. Scaling Up Your Data Warehouse with SQL Server 2008 R2 Reference: Pinal Dave (http://blog.SQLAuthority.com)   Filed under: PostADay, SQL, SQL Authority, SQL Documentation, SQL Download, SQL Query, SQL Server, SQL Tips and Tricks, T SQL, Technology

• How to zero out a drive?

  - by Mohd Arafat Hossain

  I'm currently running Ubuntu 12.04 and want to completely format my laptop so I can install Windows 7 (replace Ubuntu). When I put in my bootable USB with the OS it just shows a black screen with a white blinking cursor on the top left corner. I wait for hours (to be specific 5 whole hours) waiting for something to happen but I get nothing, so I pull out the USB and my Ubuntu 12.04 loads up. Repeated this several times with putting different boot priority options on top-est that relate to USB but the results are same. I go and visit some sites on the net like this http://www.techspot.com/community/topics/cant-replace-ubuntu-with-windows.175716/ that say I have to zero out my hard drive. My question is how? Note: Erasing out all my data is no problem cause I have nothing important to backup. If I have to lose my primary OS (Ubuntu 12.04) in the process I am ready to as my aim is just to install Windows 7 successfully. Please don't answer that there is something wrong with my USB or my USB reader/port/hardware or the content inside the USB cause they all works fine on my brothers PC as it boots up flawlessly.

• Ubuntu 12.04 NVIDIA GeForce Go 7600 black screen during boot

  - by Florian Schmidt

  I'm using Ubuntu as the only operating system since two years. In the first Ubuntu versions I had seen my BIOS screen and the boot screens. Actually im using Ubuntu 12.04 and my screen stays black until Ubuntu is started (both screens are missing). I guess this situation appeared the first time in Ubuntu 11 (not sure). I searched via google and tried the popular activities but was not able to fix my issue. I opened the laptop and checked all connections. I'm using boot option nomodeset. I had a look through many many web pages. I don't know how to continue and hope somebody could be helpful.

• Do you think natively compiled languages have reached their EOL?

  - by Yuval A

  If we look at the major programming languages in use today it is pretty noticeable that the vast majority of them are, in fact, interpreted. Looking at the largest piece of the pie we have Java and C# which are both enterprise-ready, heavy-duty, serious programming languages which are basically compiled to byte-code only to be interpreted by their respective VMs (the JVM and the CLR). If we look at scripting languages, we have Perl, Python, Ruby and Lua which are all interpreted (either from code or from bytecode - and yes, it should be noted that they are absolutely not the same). Looking at compiled languages we have C which is nowadays used in embedded and low-level, real-time environments, and C++ which is still alive and kicking, when you want to get down to serious programming as close to the hardware as you can, but still have some nice abstractions to help you with day to day tasks. Basically, there is no real runner-up compiled language in the distance. Do you feel that languages which are natively compiled to executable, binary code are a thing of the past, taken over by interpreted languages which are much more portable and compatible? Does C++ mark an end of an era? Why don't we see any new compiled languages anymore? I think I should clarify: I do not want this to turn into a "which language is better" discussion, because that is not the issue at hand. The languages I gave as example are only examples. Please focus on the question I raised, and if you disagree with my statement that compiled languages are less frequent these days, that is totally fine, I am more than happy to be proved mistaken.

• Algorithm for a lucky game [on hold]

  - by Ronnie

  Assume we have the following Keno(lottery type) game: From 80 numbers(from 1 to 80), 20 are being drawn. The players choose 1 or 2 or 3..... or 12 numbers to play(12 categories). If they choose for example 4 then they win if they predict correctly a certain amount of numbers(2,3 or 4) from the 4 they have played and lose if the predict only 1 or 0 numbers. They win X times their money accordingly to some predefined factor depending on how many numbers they predict from each category. The same with the other categories. And e.g 11 out of 11 gives 250000 times your money and 12 out of 12 gives 1000000 your money. So the company would want to avoid winnings so high. Every draw by the company is being made every 5 minutes and in each draw around 120000 (let's say) different predictions(Keno tickets) are being played. Let's assume 12000 are being played in category 10 and 12000 in category 11 and also 12000 in category 12. I'm wondering if there is an algorithm to allow the company that provides the game in the 5 minutes between the drawings, to find a 20 number set, in order to avoid any "12 out of 12" and "11 out of 11" and "11 out of 12" and "10 out of 11" and "10 out of 10" winning ticket. That means is there any algorithm, where in a time of less than 1 minute approximately(in todays hardware), to be able to find a 20 number set so that none of the 12000 12 and 11 and 10 number sets that the players played(in categories 10,11 and 12) contains any winning of "12 out of 12" and "11 out of 11" and "11 out of 12" and "10 out of 11" and "10 out of 10"? Or even better the generalization of the problem: What is the best algorithm(from a perspective of minimal time), to be able to find a Y number set from numbers 1 to Z(e.g Y=20, Z=80) so that none of the X sets of K-numbers that are being played(in category K) contains more than K-m numbers from the Y-set? (Note that for Y=K and m=1 there is a practical algorithm.)

• N64oid Brings N64 Emulation to Android Devices

  - by ETC

  Craving some Ocarina of Time adventures, Super Mario 64 antics, or some Star Fox 64 flying on your Android device? N64oid brings retro emulation of Nintendo’s popular N64 console to Android devices. N64oid is an N64 console emulator for Android devices. You’ll need a copy of the $5.99 emulator, ROMs (from the usual sources, unless you’ve got a ROM ripping setup in your basement and a stack of old cartridges), and a suitably speedy Android device. Older Android devices will find the playback choppy and subpar, but newer and speedier devices like the Nexus-One and Samsung Galaxy should have no problem handling the emulator. Like all emulators N64oid is a work in progress and emulating an entire closed-system console on a totally different set of hardware is never a perfect 1:1 emulation, but if you’re a die hard fan of classic N64 titles (check out this list of top ranked titles to inspire some nostalgia) N64oid is worth the price of a burger for sure.
