• Kernel panic on reboot after failed logical volume resize

  - by Derek

  I attempted to do a logical volume resize yesterday using the follwoing commands $sudo pvdisplay "/dev/sda8" is a new physical volume of "113.11 GiB" --- NEW Physical volume --- PV Name /dev/sda8 VG Name PV Size 113.11 GiB Allocatable NO PE Size 0 Total PE 0 Free PE 0 Allocated PE 0 PV UUID jwyO1o-b2ap-CW51-kx7O-kf26-arim-SM8V6m $sudo vgextend vg /dev/sda8 sudo vgdisplay vg --- Volume group --- VG Name vg System ID Format lvm2 Metadata Areas 2 Metadata Sequence No 9 VG Access read/write VG Status resizable MAX LV 0 Cur LV 5 Open LV 5 Max PV 0 Cur PV 2 Act PV 2 VG Size 131.74 GiB PE Size 4.00 MiB Total PE 33725 Alloc PE / Size 4769 / 18.63 GiB Free PE / Size 28956 / 113.11 GiB VG UUID AhusW2-pzFv-3W32-mpv2-s5VG-FN7S-kVSadx $sudo lvresize -L +20GB /dev/mapper/vg-var So as you can see, it looks like adding the physical volume to the vg worked, because i see free space available there. When I typed the lvresize command, it never returned. I let this run overnight in the background, but this morning I still couldnt successfully do a "pvdisplay" or "lvdisplay" because I think it was waiting on a lock or something, so the command never returned. When i went to log onto the server's console, I saw a bunch of messages like: rcu_sched_state detected stall on cpu 2 Now when I boot, I get a kernel panic error, and a message about not being able to mount /mapper/vg-root cannot open root device "mapper/vg-root" or unknown_block(0,0) Kernel Panic -not syncing: VFS: Unable to mount root file system on unknown_block(0,0) What should I do to get my system back up and running? Did I attempt to do the logical volume resize correctly? Thanks

• Processing component pools problem - Entity Subsystem

  - by mani3xis

  Architecture description I'm creating (designing) an entity system and I ran into many problems. I'm trying to keep it Data-Oriented and efficient as much as possible. My components are POD structures (array of bytes to be precise) allocated in homogeneous pools. Each pool has a ComponentDescriptor - it just contains component name, field types and field names. Entity is just a pointer to array of components (where address acts like an entity ID). EntityPrototype contains entity name and array of component names. Finally Subsystem (System or Processor) which works on component pools. Actual problem The problem is that some components dependents on others (Model, Sprite, PhysicalBody, Animation depends on Transform component) which makes a lot of problems when it comes to processing them. For example, lets define some entities using [S]prite, [P]hysicalBody and [H]ealth: Tank: Transform, Sprite, PhysicalBody BgTree: Transform, Sprite House: Transform, Sprite, Health and create 4 Tanks, 5 BgTrees and 2 Houses and my pools will look like: TTTTTTTTTTT // Transform pool SSSSSSSSSSS // Sprite pool PPPP // PhysicalBody pool HH // Health component There is no way to process them using indices. I spend 3 days working on it and I still don't have any ideas. In previous designs TransformComponent was bound to the entity - but it wasn't a good idea. Can you give me some advices how to process them? Or maybe I should change the overall design? Maybe I should create pools of entites (pools of component pools) - but I guess it will be a nightmare for CPU caches. Thanks

• Bounding volume hierarchy - linked nodes (linear model)

  - by teodron

  The scenario A chain of points: (Pi)i=0,N where Pi is linked to its direct neighbours (Pi-1 and Pi+1). The goal: perform efficient collision detection between any two, non-adjacent links: (PiPi+1) vs. (PjPj+1). The question: it's highly recommended in all works treating this subject of collision detection to use a broad phase and to implement it via a bounding volume hierarchy. For a chain made out of Pi nodes, it can look like this: I imagine the big blue sphere to contain all links, the green half of them, the reds a quarter and so on (the picture is not accurate, but it's there to help understand the question). What I do not understand is: How can such a hierarchy speed up computations between segments collision pairs if one has to update it for a deformable linear object such as a chain/wire/etc. each frame? More clearly, what is the actual principle of collision detection broad phases in this particular case/ how can it work when the actual computation of bounding spheres is in itself a time consuming task and has to be done (since the geometry changes) in each frame update? I think I am missing a key point - if we look at the picture where the chain is in a spiral pose, we see that most spheres are already contained within half of others or do intersect them.. it's odd if this is the way it should work.

• Rotating wheel with touch adding velocity

  - by Lewis

  I have a wheel control in a game which is setup like so: - (void)ccTouchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [touches anyObject]; CGPoint location = [touch locationInView:[touch view]]; location = [[CCDirector sharedDirector] convertToGL:location]; if (CGRectContainsPoint(wheel.boundingBox, location)) { CGPoint firstLocation = [touch previousLocationInView:[touch view]]; CGPoint location = [touch locationInView:[touch view]]; CGPoint touchingPoint = [[CCDirector sharedDirector] convertToGL:location]; CGPoint firstTouchingPoint = [[CCDirector sharedDirector] convertToGL:firstLocation]; CGPoint firstVector = ccpSub(firstTouchingPoint, wheel.position); CGFloat firstRotateAngle = -ccpToAngle(firstVector); CGFloat previousTouch = CC_RADIANS_TO_DEGREES(firstRotateAngle); CGPoint vector = ccpSub(touchingPoint, wheel.position); CGFloat rotateAngle = -ccpToAngle(vector); CGFloat currentTouch = CC_RADIANS_TO_DEGREES(rotateAngle); wheelRotation += (currentTouch - previousTouch) * 0.6; //limit speed 0.6 } } I update the rotation of a the wheel in the update method by doing: wheel.rotation = wheelRotation; Now once the user lets go of the wheel I want it to rotate back to where it was before but not without taking into account the velocity of the swipe the user has done. This is the bit I really can't get my head around. So if the swipe generates a lot of velocity then the wheel will carry on moving slightly in that direction until the overall force which pulls the wheel back to the starting position kicks in. Any ideas/code snippets?

• Sharing an internet connection through the Ethernet port

  - by Bob Cunningham

  I have a small living room PC (Bohica, running fully-updated Ubuntu 10.10/Maverick) connected to my HDTV that I use for web browsing and media streaming. It connects via WiFi (wlan0) to my Fedora server (Snafu) that in turn connects to the internet. I use static addressing, and everything has been working fine. I just got a Blu-ray player, and I'd like to give it wired network access to the internet via Bohica's available wired ethernet port (eth0). So far, I haven't been to get eth0 and the network configured to get the Blu-ray player talking to the internet. Here's my wlan0 configuration: ip4 addr: 192.168.0.100 mask: /24 (255.255.255.0) gateway: 192.168.0.4 (fedora box) The Blu-ray player is set to an IP of 192.168.0.98/24, with the same gateway as above. I want eth0 set to an IP of 192.168.0.99/24, but when I do this using nm-connection-editor I lose internet access (the system tries to use eth0 as the default internet access interface). How do I get my blu-ray player to talk to the internet through Bohica, and do so without disrupting my current (working) network? Thanks. Edit: Here's the relevant output from nm-tool with the Blu-ray player connected: $ nm-tool NetworkManager Tool State: connected - Device: eth0 Type: Wired Driver: forcedeth State: disconnected Default: no HW Address: 90:FB:A6:2C:94:32 Capabilities: Carrier Detect: yes Speed: 100 Mb/s Wired Properties Carrier: on - Device: wlan0 [wlan0] Type: 802.11 WiFi Driver: ndiswrapper State: connected Default: yes HW Address: 00:26:5A:C0:D0:05 IPv4 Settings: Address: 192.168.0.100 Prefix: 24 (255.255.255.0) Gateway: 192.168.0.4

• How to build the mainline kernel source package?

  - by Maxime R.

  Ubuntu kernel PPA only provides linux-headers*.deb and linux-image*.deb packages. How can I build the corresponding linux-source*.deb package ? Context: I'm currently running Ubuntu 11.10 with the mainline kernel (3.2 rc6 now) to get a better support for my sandybridge IGP (Dell E6420 laptop with intel i5-2520M CPU). Appears, i'd like to install this touchpad driver, ALPS touchpads being badly supported (see previous link bug report), while waiting for upstream support in kernel version 3.3. Problem is, DKMS keeps complaining about not finding the full kernel source: Module build for the currently running kernel was skipped since the kernel source for this kernel does not seem to be installed. Appears I may not need the full source but I'd still like to try having it installed to see if it solve my problem. What I tried : Uncompressing the kernel.org source archive in /usr/src/. DKMS still complaining. Manually updating the kernel source package with uupdate and the mainline source package like explained here. Did not succeed. Manually building the linux-source package following @roadmr and @elmicha instructions. I eventually succeeded to build it but DKMS still complained about the missing source. At last I noticed an error I did not catch in the first place while reinstalling the kernel headers. Appears the .deb I got may have been corrupted, downloading it again did the trick :) Alas, while DKMS agreed to compile the module i ran into the following error which appears to have already been reported. This issue isn't yet solved but I won't try to because of the following: in the end I decided to test the precise kernel version 3.2-rc6 through the xorg-edgers ppa which appears to be correctly patched: it works. Nevertheless, it might still be of some interest to know how to build the mainline linux-source package as the Ubuntu Kernel Team doesn't provide it. Not to mention that I learned a lot in the process ^^

• Problems with Ubuntu and AMD A10-4655M APU

  - by Robert Hanks

  I have a new HP Sleekbook 6z with AMD A10-4655M APU. I tried installing Ubuntu with wubi--the first attempt ended up with a 'AMD unsupported hardware' watermark that I wasn't able to remove (the appeared when I tried to update the drivers as Ubuntu suggested) On the second attempted install Ubuntu installed (I stayed away from the suggested drivers) but the performance was extremely poor----as in Windows Vista poor. I am not sure what the solution is--if I need to wait until there is a kernel update with Ubuntu or if there are other solutions--I realise this is a new APU for the market. I would love to have Ubuntu 12.04 up and running--Windows 7 does very well with this new processor so Ubuntu should, well, be lightening speed. The trial on the Sleekbook with Ubuntu 12.10 Alpha 2 release was a complete failure. I created a bootable USB. By using either the 'Try Ubuntu' or 'Install Ubuntu' options resulted in the usual purple Ubuntu splash screen, followed by nothing...as in a black screen without any hint of life. Interestingly one can hear the Ubuntu intro sound. In case you are wondering, this same USB was trialed subsequently on another computer with and Intel Atom Processor. Worked flawlessly. Lastly the second trial on the Sleekbook resulted in the same results as the first paragraph. Perhaps 12.10 Beta will overcome this issue, or the finalised 12.10 release in October. I don't have the expertise to know what the cause of the behaviour is-the issue could be something else entirely. Sadly, the Windows 7 performance is very good with this processor-very similar and in some instances better to the 2nd generation Intel i5 based computer I use at my workplace. Whatever the cause is for the performance with Ubuntu 12.04 or 12.10 Alpha 2, the situation doesn't bode well for Ubuntu. Ubuntu aside, the HP Sleekbook is a good performer for the price. I am certain once the Ubuntu issue is worked on and solutions arise, the Ubuntu performance will probably be better than ever.

• How can I debug VNC screen repainting issues?

  - by stevecoh1

  I have what some might consider a trivial use for VNC, but I'd like to get it to work and it's technically interesting to me. My use case is that I'd like sometimes to be able to control my desktop from my living room while watching tv. The desktop runs Ubuntu, currently 12.04, but that may change soon. I'm using the default Vino server. I'd like to control it from my IPad and I have a nicely performing WiFi. I got the well-regarded (if reviews can be believed) app Vnc Viewer for the iPad. It's not working as well as I'd hoped. The problem is the speed of repainting. It's abysmally slow. I can click a close button, walk over to the desktop and see that the window has closed, but on the iPad, the VNC Client won't show the close for minutes if ever. I've noticed that CLOSING windows takes a lot longer to update than to open them. So the question is is this primarily client or server-caused? And if server-caused what can be done about it? Is Vino the best client or is something else better? Thanks

• Accessing second hard drive

  - by Jonathan

  Hi, So I recently installed Ubuntu 10.10 64-bit on my computer. I installed it on my 60gb SSD hard drive, and in the installation it never acknowledged the existence of my second hard drive. The hard drive that I keep all my files on, and which I want to make my home folder if I can, is a Western Digital Caviar Black 1TB SATA 6Gb/s 64MB cache (WD1002FAEX). I've read the following: https://help.ubuntu.com/community/Mount but honestly cannot work out how to access the hard drive from my Ubuntu installation. I did have Windows 7 64-bit prior to installing Ubuntu. I have backed up all the files on the hard drive, but if I could just access them straight off that would be super cool. Does anyone know how I can use the second hard drive? Thank you for your help EDIT: The following directories are currently in my /dev/ folder: ati/, block/, bsg/, bus/, char/, cpu/, isk/, input/, mapper/, net/, pktcdvd/, pts/, shm/, snd/, and usb/ EDIT: Result from sudo fdisk -l Disk /dev/sda: 60.0 GB, 60022480896 bytes 255 heads, 63 sectors/track, 7297 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x000d2dfd Device Boot Start End Blocks Id System /dev/sda1 * 1 6994 56174592 83 Linux /dev/sda2 6994 7298 2438145 5 Extended /dev/sda5 6994 7298 2438144 82 Linux swap / Solaris

• Using EC2 instance as main development platform

  - by David

  My problem I am working as a consultant for various companies. Each company provides me with a laptop where with their software on and I also have my own where I have my development environment. I tend to buy a new laptop every second year and find myself spending lots of time configuring and installing software. I also sometimes spend a lot of time waiting for my laptop to process things. To solve all these issues, I am now considering using EC2 (running windows instances) as my main development platform and just access this from any PC I happen to be at. I calculated that running the High-CPU On-Demand Instances (medium) for 8 hours a day for a year costs me 580$, which is acceptable. I imagine that when I approach the workplace each day, I will make a single click my phone to fire up the instance, so it is ready when I get to work. I should have different icons on my phone to fire up the various instance types. The same software should of course automatically be loaded on the various hardware (sometimes I would even need their instance with 68.4 GB of memory). Another advantage is that if I am having a specific problem with my instance, I could fire up another instance and have someone look into the problem and update the image. My question: Does anyone have experience with such a setup on EC2? What kind of problems do you forsee?

• An Oracle's Interns Story by Samarth Varshney

  - by user769227

  I have written a short write-up about my experience at Oracle and am attaching some pics along:  I joined Oracle on 5th January 2011 as part of my internship program in BITS Pilani Goa Campus. In the short period of six months, I had the most beautiful and interesting time of my life. It was fun to work in Oracle, thanks to the whole team. I had an excellent manager, simple and sophisticated, who gave me the utmost enthusiasm to work. I gained a lot of knowledge during my internship, thanks to my colleagues. They were very helpful and motivated us (interns) in every possible way. In the initial stages of work, in which you know almost nothing, they helped me gain knowledge at a rapid speed. Thanks to the vast database of study material at the Oracle site, that I could start on with my project in a very short time.  For me, the time flew like anything and made the 6 months look like a few days. It was probably due to the team, that the work was so much fun. We had our deadlines but had full freedom as to how to work and when to work. I don't remember a single instance, in which I was working and not listening to songs. I mean it will always be a time to remember. I hope to join this company and make this time last forever.  Samarth

• Horse Drawn Fiber Optics Bring Broadband to Remote Areas

  - by Jason Fitzpatrick

  When you think of fiber optics and high speed internet the last thing you likely think of is… horses. Yet horses have been put to use rolling out fiber optics to remote rural locations. In Vermont a Belgium draft horse named Fred, seen in the photo above being tended by his handler Claude, is a distinctly 19th century solution to a 21st century problem; how to run fiber optic cable through remote areas where trucks cannot easily pass. The man and animal are indispensable to cable and phone-service provider FairPoint Communications because they easily can access hard-to-reach job sites along country roads, which bulky utility trucks often cannot. “It just saves so much work – it would take probably 15 guys to do what Fred and Claude can do,” said Paul Clancy, foreman of a line crew from FairPoint. “They can pull 5,000 feet of cable with no sweat.” You can read more about the use of draft horses to draw lines and the roll out of broadband to rural Vermont at the link below.

• How to reduce the fan noise and how to increase battery life in ubuntu 11.10/12.04?

  - by mehdi

  I have a brand new Sony Vaio S series laptop.(VPCSA2DGX) It came factory installed with Windows 7 professional Edition 64bit. Runs Intel core i5, 500 GB HDD , 4GB Ram. First I installed ubuntu 11.10 64 bit along side Windows to dual boot. Later,since the problem did not solve, I installed ubuntu 12.04 64bit along side Windows to dual boot. However the problem keeps annoying me. Problem: When running ubuntu 11.10/12.04, the battery lasts only about 1.5 hours. The Fan runs loud and continuously. And there is a lot of heat generated. System monitor shows less than 5% CPU used. My laptop enjoys hybrid graphic and I tried turning off ADM graphic card and keep Intel graphic card on. However I can not get the Fan noise or heat to go away and consequently the battery drain continues. BTW, in windows, the laptop gives 4-5 hours of battery power, Fan is silent and there is no heat problem. Any ideas on how to reduce the fan noise and how to increase battery life in ubuntu 11.10/12.04?

• Collision within a poly

  - by G1i1ch

  For an html5 engine I'm making, for speed I'm using a path poly. I'm having trouble trying to find ways to get collision with the walls of the poly. To make it simple I just have a vector for the object and an array of vectors for the poly. I'm using Cartesian vectors and they're 2d. Say poly = [[550,0],[169,523],[-444,323],[-444,-323],[169,-523]], it's just a pentagon I generated. The object that will collide is object, object.pos is it's position and object.vel is it's velocity. They're both 2d vectors too. I've had some success to get it to find a collision, but it's just black box code I ripped from a c++ example. It's very obscure inside and all it does though is return true/false and doesn't return what vertices are collided or collision point, I'd really like to be able to understand this and make my own so I can have more meaningful collision. I'll tackle that later though. Again the question is just how does one find a collision to walls of a poly given you know the poly vertices and the object's position + velocity? If more info is needed please let me know. And if all anyone can do is point me to the right direction that's great.

• recent unreliable wireless connection on 10.04 and 10.10

  - by gabkdlly

  Recently, my internet connection over wireless has become unreliable, on both a Dell laptop running Ubuntu 10.04 as well as my Desktop running Ubuntu 10.10 . The problem does not seem to occur on a laptop running Windows Vista. The problem does not seem to occur on my Openmoko Freerunner ( running Android 1.5 ), though I hardly ever use this device to connect over WLAN, so the problem may have just slipped by. This problem does not seem to appear when I boot into Ubuntu 9.10 from a live CD ( more precisely, I was able to ping fu-berlin.de for an hour without any packet loss ). Under Ubuntu 10.10, I am experiencing about 33% packet loss. On my main Ubuntu Desktop, I have tried the following wireless devices: a Longshine PCI card ( an old device with an RTL8180L chip ) a D-Link DWL-510 PCI card ( this device threw warnings in dmesg ) a USB device from MSI ( US54EX ). Usually my wireless network shows up in the network manager with a normal signal strength, even when the connection speed is slow ( which happens often ) or the connection gets reset ( asking me to click connect to re-authenticate my wireless connection ). I have observed this problem with a Netgear KWGR614 Router ( with the manufacturers firmware ), as well as with a TP-LINK TL-WR741ND router running OpenWrt. Taking a look at my routers logs, I find many instances of the following line: Tuesday,04 Jan 2011 03:53:01 [TCP SYN Flood][Deny access policy matched, dropping packet] I know that the Netgear router is susceptible to denial of service attacks, as I have previously been able to disrupt its operation by putting an nmap scan into a while loop. I use WEP on the Netgear router and WPA on the TP-LINK to encrypt the wireless connections. Is it possible that someone is jamming my signal ?

• Internet is far slower in Ubuntu than Windows 7 on dual-booted machine

  - by Tim

  Edit: I'll leave the original post as-is, but after further investigation, it appears that the problem is something to do with my wi-fi card. Speeds are normal when I connect via cable. Edit 2: Problem was solved. It was something to do with the wireless card drivers. I normally use Windows 7 on my laptop and have internet speeds that are normally about 15-20 Mb/s. I have recently dual-booted with Ubuntu 12.10, and have noticed that internet speeds are drastically slower in Ubuntu. When tested, speeds range from 0.2-2 Mb/s, although occasionally being significantly faster than that or even stopping completely for short periods of time. I've also noticed that when first booting into Ubuntu, speeds start fairly fast, and drop to incredibly slow with a few seconds to a few minutes. There's still some possibility that the issue may be with my ISP, as things seem slower than usual even in Windows, but I suspect that it is related to Ubuntu, as things are far slower in Ubuntu than in Windows. I'm wondering, what could be the cause of this? Potentially relevant information: -I've dual booted before on this machine with earlier versions of Ubuntu (different ISP at the time) with no problem. ISP: Rogers (Major Canadian ISP) System info (Gateway NV53a Laptop): Operating System MS Windows 7 Home Premium 64-bit CPU AMD Phenom II N970 Caspian 45nm Technology RAM 6.00 GB Dual-Channel DDR3 @ 664MHz (9-9-9-24) Motherboard Gateway SJV51_DN (Socket S1G4) Graphics Generic PnP Monitor (1366x768@60Hz) ATI Mobility Radeon HD 4250 (Acer Incorporated [ALI]) Hard Drives 733GB TOSHIBA TOSHIBA MK7559GSXP ATA Device (SATA) Networking info: Connected through Wi-Fi Atheros AR5B97 Wireless Network A

• Sprite Sheets in PyGame?

  - by Eamonn

  So, I've been doing some googling, and haven't found a good solution to my problem. My problem is that I'm using PyGame, and I want to use a Sprite Sheet for my player. This is all well and good, and it would be too, if I wasn't using a Sprite Sheet strip. Basically, if you don't understand, I have a strip of 32x32 'frames'. These frames are all in an image, along side each other. So, I have 3 frames in 1 image. I'd like to be able to use them as my sprite sheet, and not have to crop them up. I have used an awesome, popular and easy-to-use game framework for Lua called LÖVE. LÖVE has these things called "Quads". They are similar to texture regions in LibGDX, if you know what they are. Basically, quads allow you to get parts of an image. You define how large a quad is, and you define parts of an image that way, or 'regions' of an image. I would like to do something similar to this in PyGame, and use a "for" loop to go through the entire image width and height and mark each 32x32 area (or whatever the user defines as their desired frame width and height) and store that in a list or something for use later on. I'd define an animation speed and stuff, but that's for later on. I've been looking around on the web, and I can't find anything that will do this. I found 1 script on the PyGame website, but it crashed PyGame when I tried to run it. I tried for hours trying to fix it, but no luck. So, is there a way to do this? Is there a way to get regions of an image? Am I going about this the wrong way? Is there a simpler way to do this? Thanks! :-)

• How can I tell GoogleBot that a subdirectory is now a subdomain?

  - by cwd

  I had about a million pages of a catalog indexed under a subdirectory, and now that's moved to a subdomain. GoogleBot is crawling each one of them and getting a 301 redirect to the new location. Even though I have set up the redirect rule in the apache sites-enabled configuration file, (i.e. it's early on when apache does the redirect - PHP is not even getting loaded), even though I have done that, the server isn't handling the load well. GoogleBot is making around 5 requests per second, and on top of my normal traffic that is hiking up the CPU for a few hours at a time. I checked in Webmaster Tools and the corresponding documentation for a way to let Google know that the content had been moved from a subdirectory to a subdomain, but with little luck. Basically the most helpful thing I saw said to just send 301 headers for the new location. How can I tell GoogleBot that a subdirectory is now a subdomain? If that is not an option, how can I more efficiently send 301 redirects out for a particular subdomain? I was thinking perhaps the Nginx server but I'm not sure that I can run both Apache and Nginx side by side on port 80 for different subdomains.

• Price Drop for Processor based License on Exalytics

  - by Mike.Hallett(at)Oracle-BI&EPM

  ·       33% reduction in the list `per processor` license pricing for the Oracle BI Foundation Suite ·       New capacity-based licensing which allows customers to think big & start small, significantly lowering the entry price point for an Exalytics. Oracle BI Software List Price changes In response to new powerful platforms like the in-memory Oracle Exalytics with 40 cpu cores (counted under Oracle pricing policy as 20 “processors”), the list price of “Oracle BI Foundation Suite” (BIFS) is reduced by 33% from $450K per processor to $300K per processor. Capacity-based licensing on Exalytics (Trusted Partitions) “Capacity-based pricing” for the BIFS, Endeca, Essbase and Times Ten for Exalytics software is now available for Exalytics systems. This is delivered using “Oracle VM” (OVM).  We still ship a full Exalytics machine to all customers, but they may choose to only use and license a subset of the processors installed in the machine.   Customers can license Exalytics software in units of 5 “processors”: 5, 10, 15 or the full capacity 20.   As the customer’s implementation and workload increases, it is a simple matter to license additional processors and, using OVM, make them available to the BI or EPM application. Endeca Information Discovery now available on Exalytics Oracle has also announced the certification of “Oracle Endeca Information Discovery” (EID) on the Exalytics machine.    EID can be licensed alone or in combination with the BIFS & Times Ten for an Exalytics stack, and also participates in the capacity based pricing outlined above.   The Exalytics hardware is the perfect platform for EID, and provides superb power and performance for this in-memory hybrid text-search-analytics.   For more information : Oracle Price lists Oracle Partitioning Policy Discussion by Mark Rittman (Rittman Mead Consulting ltd.) on Oracle Trusted Partitions for Oracle Engineered Systems, Oracle Exalytics and Updated BI Foundation Pricing.

• Should you put personal beliefs in your program?

  - by TheLQ

  Recently I've found two examples of programmer's personal beliefs in programs that have removed or crippled useful functionality uTorrent using KB (rarely used) vs Kb (what most ISPs and other programs use as their metric) in their current connection speed. Various attempts by others and me to give options to at least give an option to show in Kb have ended with "ISPs should use KB" Kleopatra (gpg4Win key manager) not having PGP Key Pictures since they "give a false sense of security" and "increase the size of certificates". While the latter is true, the former is debatable. Both of these hurt the program and its usefulness to me. uTorrent's forums used to be filled with people saying they have 10 Mb download pipe but uTorrent only goes up to 2 MB (not knowing that Mb != MB), and with feature requests to show in Mb. Kleopatra has lost usefulness to me since I don't have the functionality to add pictures to PGP keys. These all are political statements; developers attempting to make change in, in their minds important, issues. But should this come at a cost to end user functionality? If a programmer heavily believes X but everyone else believes Y, should the programmer refuse to add support for Y because in their mind X is horrible? In short, should a programmer make political statements in their program?

• How to Print From Metro Apps in Windows 8

  - by Taylor Gibb

  Printing has become an application aware feature in Metro applications. This makes the outcome of a print job different from application to application, but the question remains, how do you print? Using the Keyboard Not all apps support printing in Windows 8, a good example of one that does is Mail. So fire up the default Mail app select an email you want to print. When you are ready, go ahead and press the ctrl + P keyboard combination. This will bring up a list of available print devices on the right-hand side, you can use the up and down arrows to select a printer. You will get most of the options you are use to when printing, so once you have set up your preferences go ahead and hit the print button. Using the Mouse If you would rather use your mouse, move it to the bottom right hand corner of your screen, which will bring up the Charms bar, from here you will need to click on the devices charm. Using this will list your printers as well as other devices, so make sure you select a printer. That’s all there is to it.

• forward motion car physics - gradual slow

  - by spartan2417

  Im having trouble creating realistic car movements in xna 4. Right now i have a car going forward and hitting a terminal velocity which is fine but when i release the up key i need to the car to slow down gradually and then come to a stop. Im pretty sure this is easy code but i cant seem to get it to work the code - update if (Keyboard.GetState().IsKeyDown(Keys.Up)) { double elapsedTime = gameTime.ElapsedGameTime.Milliseconds; CalcTotalForce(); Acceleration = Vector2.Divide(CalcTotalForce(), MASS); Velocity = Vector2.Add(Velocity, Vector2.Multiply(Acceleration, (float)(elapsedTime))); Position = Vector2.Add(Position, Vector2.Multiply(Velocity, (float)(elapsedTime))); } added functions public Vector2 CalcTraction() { //Traction force = vector direction * engine force return Vector2.Multiply(forwardDirection, ENGINE_FORCE); } public Vector2 CalcDrag() { //Drag force = constdrag * velocity * speed return Vector2.Multiply(Vector2.Multiply(Velocity, DRAG_CONST), Velocity.Y); } public Vector2 CalcRoll() { //roll force = const roll * velocity return Vector2.Multiply(Velocity, ROLL_CONST); } public Vector2 CalcTotalForce() { //total force = traction + (-drag) + (-rolling) return Vector2.Add(CalcTraction(), Vector2.Add(-CalcDrag(), -CalcRoll())); } anyone have any ideas?
