  • Data Aggregation of CSV files java

    - by royB
    I have k csv files (5 csv files for example), each file has m fields which produce a key and n values. I need to produce a single csv file with aggregated data. I'm looking for the most efficient solution for this problem, speed mainly. I don't think by the way that we will have memory issues. Also I would like to know if hashing is really a good solution because we will have to use 64 bit hashing solution to reduce the chance for a collision to less than 1% (we are having around 30000000 rows per aggregation). For example file 1: f1,f2,f3,v1,v2,v3,v4 a1,b1,c1,50,60,70,80 a3,b2,c4,60,60,80,90 file 2: f1,f2,f3,v1,v2,v3,v4 a1,b1,c1,30,50,90,40 a3,b2,c4,30,70,50,90 result: f1,f2,f3,v1,v2,v3,v4 a1,b1,c1,80,110,160,120 a3,b2,c4,90,130,130,180 algorithm that we thought until now: hashing (using concurentHashTable) merge sorting the files DB: using mysql or hadoop or redis. The solution needs to be able to handle Huge amount of data (each file more than two million rows) a better example: file 1 country,city,peopleNum england,london,1000000 england,coventry,500000 file 2: country,city,peopleNum england,london,500000 england,coventry,500000 england,manchester,500000 merged file: country,city,peopleNum england,london,1500000 england,coventry,1000000 england,manchester,500000 The key is: country,city. This is just an example, my real key is of size 6 and the data columns are of size 8 - total of 14 columns. We would like that the solution will be the fastest in regard of data processing.

  • 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?

  • wynapse.com down last night, SC tonight

    - by Dave Campbell
    In an industry segment that nobody is ever 'asleep', I suppose no time is a good time to take SQL Server down for upgrades, and I had forgotten that my host was going to be doing that. Last night about 9pm (Arizona), in the middle of working on a blog post, things started going wonky and I finally realized everything was ok except for SQL Server. I turned in a ticket on it and was reminded about the maintenance schedule... guess I file those away in memory and just assume they'll happen while I'm asleep :) So, looking at the schedule, it appears that SQL Server for SilverlightCream is going to be down tonight. Minimum is 9-12pm Arizona time... mileage and time may vary. Since all the posts are run through SC to get the Skim count, having SQL down sucks, but I'd rather we got maintenance than have to react to a crash because of something that wasn't maintained. I'll try to get the next 'Cream post out early so that the bulk of folks can dig through it prior to the outage. Meanwhile, for those of you in Phoenix, tonight is our Phoenix Silverlight User Group April meeting, and Joel Neubeck is going to be giving us the run-through on Windows Phone 7! We're not as advanced as those MVP rock-stars in California like Victor Gaudioso who streams his user group meeting, so you'll just have to show up for the goodness! And for anyone that's interested, here's some WP7 bling for your desktop... I want some of this real bad for my laptop! Get the full image in the post by Ozymandias:

  • Hybrid USB Install Method - netboot and iso

    - by Samus Arin
    I was following the steps here ("Preparing Files for USB Memory Stick Booting") https://help.ubuntu.com/10.04/installation-guide/i386/boot-usb-files.html to create a installation usb drive for 12.1. The very first paragraph of the article states "The second is to also copy a CD image onto the USB stick and use that as a source for packages, possibly in combination with a mirror." However, the only instructions mentioned regarding an iso image is to simply copy one somewhere on the drive (after its been made bootable and syslinux, vmlinuz and initrd.gz installed/copied): "you should now copy an Ubuntu ISO image onto the stick." I thought it strange there where no configuration steps for "pointing" the kernel to the iso (like a line in syslinux.cfg or a boot: option or something), but went ahead with the install anyway. I don't think the iso was used at all, it appeared that all the OS files where downloaded during the install process. Therefore, I was wondering if anyone knew how to use this local iso image in this particular installation technique (I know the image can be installed with dd, but thats a different technique), b/c I need to reinstall (I installed unity, but it's wayy to much for my little Atom based netbook) ? Thank you.

  • Is comparing an OO compiler to a SQL compiler/optimizer valid?

    - by Brad
    I'm now doing a lot of SQL development at my new job where as before I was doing Object Oriented desktop app stuff. I keep running across very large scripts (thousands of lines) and wanting to refactor in some way. I am seeing that SQL is a different sort of beast and it's probably fine to have these big scripts for the most part but while explaining this to me people are also insisting that the whole idea of refactoring is bad. That stuff like the .NET compiler are actually burdened by refactored code and that a big wall of code is more efficient and better design than code designed for reuse, readability and scalability. The other argument is that OO compilers are almost dangerously inefficient and don't have efficient memory management or runs too many CPU instructions compared to older "simpler" compilers and compared to SQL. Are these valid complaints? Even if some compiler like a C compiler is modestly more "efficient" (whatever that means on this high of a level without seeing code) would you want to write applications in C over C# or Java? Is comparing an OO compiler to a SQL compiler/optimizer even valid?

  • What is the rationale behind Apache Jena's *everything is an interface if possible* design philosophy?

    - by David Cowden
    If you are familiar with the Java RDF and OWL engine Jena, then you have run across their philosophy that everything should be specified as an interface when possible. This means that a Resource, Statement, RDFNode, Property, and even the RDF Model, etc., are, contrary to what you might first think, Interfaces instead of concrete classes. This leads to the use of Factories quite often. Since you can't instantiate a Property or Model, you must have something else do it for you --the Factory design pattern. My question, then, is, what is the reasoning behind using this pattern as opposed to a traditional class hierarchy system? It is often perfectly viable to use either one. For example, if I want a memory backed Model instead of a database-backed Model I could just instantiate those classes, I don't need ask a Factory to give me one. As an aside, I'm in the process of writing a library for manipulating Pearltrees data, which is exported from their website in the form of an RDF/XML document. As I write this library, I have many options for defining the relationships present in the Peartrees data. What is nice about the Pearltrees data is that it has a very logical class system: A tree is made up of pearls, which can be either Page, Reference, Alias, or Root pearls. My question comes from trying to figure out if I should adopt the Jena philosophy in my library which uses Jena, or if I should disregard it, pick my own design philosophy, and stick with it.

  • PowerShell One Liner: Duplicating a folder structure in a Sharepoint document library

    - by Darren Gosbell
    I was asked by someone at work the other day, if it was possible in Sharepoint to create a set of top level folders in one document library based on the set of folders in another library. One document library has a set of top level folders that is basically a client list and we needed to create the same top level folders in another library. I knew that it was possible to open a Sharepoint document library in explorer using a UNC style path and that you could map a drive using a technique like this one: http://www.endusersharepoint.com/2007/11/16/can-i-map-a-document-library-as-a-mapped-drive/. But while explorer would let us copy the folders, it would also take all of the folder contents too, which was not what we wanted. So I figured that some sort of PowerShell script was probably the way to go and it turned out to be even easier than I thought. The following script did it in one line, so I thought I would post it here in my "online memory". :) dir "\\sharepoint\client documents" | where {$_.PSIsContainer} | % {mkdir "\\sharepoint\admin documents\$($_.Name)"} I use "dir" to get a listing from the source folder, pipe it through "where" to get only objects that are folders and then do a foreach (using the % alias) and call "mkdir".

  • How do I install windows wireless driver for TP-Link TL-WN7200ND

    - by Jim
    I'm using the TP-Link TL-WN7200ND USB wireless adapter. I have downloaded the Windows drivers and updated Ubuntu to 10.10 by manually connecting the computer to the router. I also installed ndiswrapper-gtk. I get a Windows Wireless Drivers in my Administration menu, and I was able to get it to read the Windows 7 .inf file. The .inf for XP does not work. It adds it and the driver appears in the list with "Hardware: present". I set up the wireless connection information (ESSID and WPA2-Personal key). Problem: I don't see the network manager icon in the top right of the screen. I managed to manually start it manually using sudo services network-manager restart but it shows no connections in the menu, saying that there's nothing to manage. In my /etc/network/interfaces file I have an entry for the loopback and the standard two-liner for eth0 with dhcp. From memory, something like: iface eth0 auto eth0 dhcp I had read somewhere that 10.10 would have standard support for my wireless adapter (TL-WN7200ND) but that seems not to be the case. However, I don't ever remember having the network-manager icon in the top-right and it does not auto-start at the moment. This was originally an Ubuntu 9.10 install that I've upgraded over time. I also used to use pppoeconf to connect to the net, which might affect the /etc/network/interfaces file?

  • How important do you find exception safety to be in your C++ code?

    - by Kai
    Every time I consider making my code strongly exception safe, I justify not doing it because it would be so time consuming. Consider this relatively simple snippet: Level::Entity* entity = new Level::Entity(); entity->id = GetNextId(); entity->AddComponent(new Component::Position(x, y)); entity->AddComponent(new Component::Movement()); entity->AddComponent(new Component::Render()); allEntities.push_back(entity); // std::vector entityById[entity->id] = entity; // std::map return entity; To implement a basic exception guarantee, I could use a scoped pointer on the new calls. This would prevent memory leaks if any of the calls were to throw an exception. However, let's say I want to implement a strong exception guarantee. At the least, I would need to implement a shared pointer for my containers (I'm not using Boost), a nothrow Entity::Swap for adding the components atomically, and some sort of idiom for atomically adding to both the Vector and Map. Not only would these be time consuming to implement, but they would be expensive since it involves a lot more copying than the exception unsafe solution. Ultimately, it feels to me like that time spent doing all of that wouldn't be justified just so that the a simple CreateEntity function is strongly exception safe. I probably just want the game to display an error and close at that point anyway. How far do you take this in your own game projects? Is it generally acceptable to write exception unsafe code for a program that can just crash when there is an exception?

  • Is there a way to disable the hardware on/off switch for the Wireless interface?

    - by avee
    I have an HP 520 and is running the latest Ubuntu 11.10. The hardware works fine with Ubuntu with one exception: The device has a hardware switch for turning the wifi on and off. Every time the wi-fi is disabled through the hardware switch, I am unable to bring it on again. The message on the networking popup would be device not ready. What I am looking for is a way to disable the hardware switch altogether so that when users accidentally press the button, the wifi would not be disabled. There is no setting to disable the switch in the BIOS.

  • Designing a Content-Based ETL Process with .NET and SFDC

    - by Patrick
    As my firm makes the transition to using SFDC as our main operational system, we've spun together a couple of SFDC portals where we can post customer-specific documents to be viewed at will. As such, we've had the need for pseudo-ETL applications to be implemented that are able to extract metadata from the documents our analysts generate internally (most are industry-standard PDFs, XML, or MS Office formats) and place in networked "queue" folders. From there, our applications scoop of the queued documents and upload them to the appropriate SFDC CRM Content Library along with some select pieces of metadata. I've mostly used DbAmp to broker communication with SFDC (DbAmp is a Linked Server provider that allows you to use SQL conventions to interact with your SFDC Org data). I've been able to create [console] applications in C# that work pretty well, and they're usually structured something like this: static void Main() { // Load parameters from app.config. // Get documents from queue. var files = someInterface.GetFiles(someFilterOrRegexPattern); foreach (var file in files) { // Extract metadata from the file. // Validate some attributes of the file; add any validation errors to an in-memory // structure (e.g. List<ValidationErrors>). if (isValid) { var fileData = File.ReadAllBytes(file); // Upload using some wrapper for an ORM or DAL someInterface.Upload(fileData, meta.Param1, meta.Param2, ...); } else { // Bounce the file } } // Report any validation errors (via message bus or SMTP or some such). } And that's pretty much it. Most of the time I wrap all these operations in a "Worker" class that takes the needed interfaces as constructor parameters. This approach has worked reasonably well, but I just get this feeling in my gut that there's something awful about it and would love some feedback. Is writing an ETL process as a C# Console app a bad idea? I'm also wondering if there are some design patterns that would be useful in this scenario that I'm clearly overlooking. Thanks in advance!

  • Dummy output after upgrade from 12.04 to 12.10, even though sound card is detected

    - by user115441
    So I just recently upgraded my system from Ubuntu 12.04 to 12.10. However, when I booted into 12.10 for the first time, no sound comes out of my speakers. I checked the sound settings and the Dummy Output was the only thing showing up. I used "hwinfo --sound" to check to see if my sound card was actually installed, and it was installed. hwinfo --sound hal.1: read hal dataprocess 2687: arguments to dbus_move_error() were incorrect, assertion "(dest) == NULL || !dbus_error_is_set ((dest))" failed in file ../../dbus/dbus-errors.c line 282.

I would really appreciate any help I can get on here.

  • Blank screen after Switch User or Resume

    - by matt wilkie
    About half the time when I switch users or resume from standby or resume the screen goes blank (black). If I work the cursor keys I can hear the system bell when it gets to the end of the user list. I can also successfully login, going from memory, but screen stays black. Sometimes closing and re-opening the lid will light up the screen again. Pressing the special Function key to enable/disable external monitor connection has no effect [Fn]-[F5],[Fn]-[F6]. If none of the previous work I need to put the computer into hibernation or full power off to restore screen function. If I watch closely when switching users I think I can see the screen initially start to light up and then quickly fade to black. The computer is an Acer Aspire 3500, model ZL6, running Ubuntu 10.10 installed 2 days ago. No proprietary drivers are in use. I'll provide a list of hardware details as soon as I can figure out how to generate that (didn't there used to be an entry for hardware details under the System menu?). Possibly related questions: No resume after Hibernate or Standby When I resume from suspension - the screen is blank Switch user fails to complete successfully For what it's worth, blank after resume also used to happen occasionally when the laptop was running XP-Home, but nowhere near as often, perhaps 6 or 8 times a year. UPDATE: I found System Administration System Testing and ran the Monitor test. It went very very dark, but the window elements could be discerned, and the whole screen flashed (from very very dark to black). On the third repeat of that same test the screen went to full blaupck and stayed there. Moving the mouse, via touchpad, or touch keys did not wake it up again. I had to close the lid and put the computer into hibernate, and press the power button to restore it. UPDATE2: output of lshw: http://pastebin.com/q7n8676r, lspci: http://pastebin.com/6ujzVK4r UPDATE3: sometimes I can restore the screen by flipping to console 1 with ctrl-alt-F1 and then back to graphical with ctrl-alt-F7.

  • 12.10 visual performance using nvidia driver

    - by user100485
    My fresh ubuntu 12.10 install is slow, not something extreme but dragging windows, switching workspaces and things like that are just slow and look horrible. it feels like the fps is dropping in a game. Doing some photoshop work in windows was even a relief! This effect gets worse if I connect my external monitor. My system is an intel pentium dual core T4500 with 4gb memory and a GeForce 8200M G/integrated/SSE2 graphics chip. Nothing fancy but should be able to run ok. My "experience" in ubuntu is set to standard. (MSI cr500 laptop) I've installed the nvidia drivers, tried current and experimental and the experimental drivers seem to perform a bit better but overall bad anyway. I set the mode to adaptive in the nvidia-settings tool and it goes to maximum setting directly and doesn't come back. Using htop I found out that compiz or the X server always use a few percent of my cpu, more than I think it should and the time consumed is 5:18 for compiz, 4:33 for /usr/bin/X and 2:41 for google chrome(about 30 tabs open so not too strange I think.) What can I do to increase the visual performance cause this makes me not want to use ubuntu in public!

  • How to create per-vertex normals when reusing vertex data?

    - by Chris Smith
    I am displaying a cube using a vertex buffer object (gl.ELEMENT_ARRAY_BUFFER). This allows me to specify vertex indicies, rather than having duplicate vertexes. In the case of displaying a simple cube, this means I only need to have eight vertices total. Opposed to needing three vertices per triangle, times two triangles per face, times six faces. Sound correct so far? My question is, how do I now deal with vertex attribute data such as color, texture coordinates, and normals when reusing vertices using the vertex buffer object? If I am reusing the same vertex data in my indexed vertex buffer, how can I differentiate when vertex X is used as part of the cube's front face versus the cube's left face? In both cases I would like the surface normal and texture coordinates to be different. I understand I could average the surface normal, however I would like to render a cube. Also, this still doesn't work for texture coordinates. Is there a way to save memory using a vertex buffer object while being able to provide different vertex attribute data based on context? (Per-triangle would be idea.) Or should I just duplicate each vertex for each context in which it gets rendered. (So there is a one-to-one mapping between vertex, normal, color, etc.) Note: I'm using OpenGL ES.

  • 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...

  • Is 12.10 ready from prime time?

    - by Mikey
    I recently installed 12.10 - dual boot using Wubi. I had numerous stability problems: many sporadic, unaccounted for system errors, software that was installed and then seemed to disappear from App Launcher, etc. Machine is new HP quad with 4 gig memory - wonderful piece of hardware - definitely no hardware problems there. I went back to 12.04 (installed from ISO image, not Wubi) and it's rock solid - never any issues at all. Is 12.10 not ready for prime time? Are there fixes-updates in the pipe? Should I get a DVD disc and install 12.10 from ISO instead of Wubi? New to Linux/Ubuntu after 20 years on MS/Windows and loving it - I develop in C++ and Python - maybe will try Lazarus since I know Delphi. Would like to use the latest and greatest Ubuntu but I will not sacrifice stabilty. Are there known problems with 12.10? Would using the standard install instead of Wubi help? Seems a lot of users are voting down this question - not sure why since other users have confirmed problems.

  • Gnome 3 - Multiple Video Cards - Xinerama -- Forced Fallback Mode

    - by Alvin
    Just installed a 2nd nvidia video card -- previously had gnome 3 working perfectly with 2 monitors on a a single video card using twinview tried a number of things thus far twinview on 1 card + xinerama no xinerama no twinview various manual xorg.conf hacks based on random forums (couple references below) xinerama no twinview with and without Extensions Composite The last one is what I'm using now -- it results in a forced fallback mode with Composite Disable set at the end of xorg.conf via nvidia-settings Section "Extensions" Option "Composite" "Disable" EndSection when I disabled that last snippet it boots to gnome 3 full with the left monitor on a black screen and the middle monitor as primary but non-responsive switching to console mode Ctrl+Alt+F1 and then switching back I get 3 black screens with a mouse that can move around but nothing to interact with issue seems related to OpenGL and the multiple video cards -- I can boot into Unity without issue though my Glx-Dock shows up with the black background as barely shows in the screenshot below indicating the OpenGL is not initiated has anyone had any luck with getting Xinerama to work with Multiple NVidia Video Cards with OpenGL support? Found this in the logs while looking a bit further [ 23.208] (II) NVIDIA(1): Setting mode "nvidia-auto-select+0+0" [ 23.254] (WW) NVIDIA(1): The GPU driving screen 1 is incompatible with the rest of the [ 23.254] (WW) NVIDIA(1): GPUs composing the desktop.

  • Ubuntu 12.04 - Brightness controls not working

    - by Juan Manuel Zolezzi Volpi
    Controls from "Brightness and Lock" were not working so I've tried a solution that involved changing grub, which I'm detailing below: # If you change this file, run 'update-grub' afterwards to update # /boot/grub/grub.cfg. # For full documentation of the options in this file, see: # info -f grub -n 'Simple configuration' GRUB_DEFAULT=0 #GRUB_HIDDEN_TIMEOUT=0 GRUB_HIDDEN_TIMEOUT_QUIET=true GRUB_TIMEOUT=10 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` GRUB_CMDLINE_LINUX="quiet splash acpi_backlight=vendor" # Uncomment to enable BadRAM filtering, modify to suit your needs # This works with Linux (no patch required) and with any kernel that obtains # the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...) #GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef" # Uncomment to disable graphical terminal (grub-pc only) #GRUB_TERMINAL=console # The resolution used on graphical terminal # note that you can use only modes which your graphic card supports via VBE # you can see them in real GRUB with the command `vbeinfo' #GRUB_GFXMODE=640x480 # Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux #GRUB_DISABLE_LINUX_UUID=true # Uncomment to disable generation of recovery mode menu entries #GRUB_DISABLE_RECOVERY="true" # Uncomment to get a beep at grub start #GRUB_INIT_TUNE="480 440 1" After doing this, the brightness control dissapeared like you can see at http://screencloud.net/img/screenshots/6b90d56604b70cc749a632d0bc005a20.png Any ideas? Would love to be able to configure Brightness or even use apps like F.lux to regulate it automatically. Edit: I've modified the following line to GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi=" and now the brightness controls are back, but whatever I change the brightness remains the same. Just in case I'm using Intel H77
