  • How to mount nexus 7 file system to view files from command line

    - by knotech
    Just got a Nexus 7, switched MTP on and plugged it in. It pops right up in nautilus, is titled Nexus 7, and lets me browse all of the files. However, on the command line, it's simply listed as /media/usbdrive and when I try to list the files, nothing comes up. Do I have to manually mount it in order to navigate the files from the command line? And why is it that nautilus recognizes it, and has access immediately, but I can't get at it from the command line?

  • Find a Faster DNS Server with Namebench

    - by Mysticgeek
    One way to speed up your Internet browsing experience is using a faster DNS server. Today we take a look at Namebench, which will compare your current DNS server against others out there, and help you find a faster one. Namebench Download the file and run the executable (link below). Namebench starts up and will include the current DNS server you have configured on your system. In this example we’re behind a router and using the DNS server from the ISP. Include the global DNS providers and the best available regional DNS server, then start the Benchmark. The test starts to run and you’ll see the queries it’s running through. The benchmark takes about 5-10 minutes to complete. After it’s complete you’ll get a report of the results. Based on its findings, it will show you what DNS server is fastest for your system. It also displays different types of graphs so you can get a better feel for the different results. You can export the results to a .csv file as well so you can present the results in Excel. Conclusion This is a free project that is in continuing development, so results might not be perfect, and there may be more features added in the future. If you’re looking for a method to help find a faster DNS server for your system, Namebench is a cool free utility to help you out. If you’re looking for a public DNS server that is customizable and includes filters, you might want to check out our article on helping to protect your kids from questionable content using OpenDNS.

  • Mac OS X: Getting detailed process information (specifically its launch arguments) for arbitrary run

    - by Jasarien
    I am trying to detect when particular applications are launched. Currently I am using NSWorkspace, registering for the "did launch application" notification. I also use the runningApplications method to get apps that are currently running when my app starts. For most apps, the name of the app bundle is enough. I have a plist of "known apps" that I cross check with the name of that passed in the notification. This works fine until you come across an app that acts as a proxy for launching another application using command line arguments. Example: The newly released Portal on the Mac doesn't have a dedicated app bundle. Steam can create a shortcut, which serves as nothing more than to launch the hl2_osx app with the -game argument and portal as it's parameter. Since more Source based games are heading to the Mac, I imagine they'll use the same method to launch, effectively running the hl2_osx app with the -game argument. Is there a nice way to get a list of the arguments (and their parameters) using a Cocoa API? NSProcessInfo comes close, offering an `-arguments' method, but only provides information for its own process... NSRunningApplication offers the ability to get information about arbitrary apps using a PID, but no command line args... Is there anything that fills the gap between the two? I'm trying not to go down the route of spawning an NSTask to run ps -p [pid] and parsing the output... I'd prefer something more high level.

  • How to check system performance?

    - by Woltan
    Hi all, I am a new Ubuntu user and really like the look and the features of the OS. However, I have a feeling that the performance could be better. With that I mean: Somehow the scrolling within firefox of sites seems laggy. I do not know how I should measure it but there is a difference. Not that it is unusable but it is aggravating. Java programs are running really slow. As a comparison (I know it is not a fair one), I tried to run a game using wine. The graphic specifications using windows were much higher (1600x1200) with a high level of detail, and in ubuntu with the lowest level of detail 1024x768 was the maximum. (My graphics card is a GeForce GTS 450 with 1gb RAM) Coming to my question: Is there a way to measure the performance of 3D acceleration, java applets, firefox scrolling etc. with a tool and compare it with lets say a windows OS or other users having almost the same hardware? Maybe it is a setup issue where some fundamental drivers are missing or something!? Any help, link, suggestion is appreciated! Cherio Woltan

  • How to check if two System.Drawing.Color structures represent the same color in 16 bit color depth?

    - by David
    How can I check if two System.Drawing.Color structures represent the same color in 16 bit color depth (or generally based on the value of Screen.PrimaryScreen.BitsPerPixel)? Let's say I set Form.TransparencyKey to Value1 (of Color type), I want to check that when the user selects a new background color for the form (Value2), I don't set the entire form transparent. On 32bit color depth screens I simply compare the two values: if (Value1 == Value2) However, this does not work on 16bit color depth screens, as more Color values for the Value2 would represent the same actual 16bit color as Value1, as I found out the hard way.

  • System starts without sound in Lubuntu

    - by cipricus
    When I log in the sound is muted. Why is that? This image is from the Xfce mixer, while the lxde volume does not show that the sound is off. So, I can see the sound muted only in Xfce Mixer. But I can also start the sound in another application, Pulse Audio Volume Control, if I change a setting in Output Devices from Analog Mono Output to LFE on Mono Separate Devices: The Analog Mono Output option here sets in fact the Xfce Mixer in the mute position from the first image. Could this be related to managing sessions (and therefore to these question)? This happens in LXDE session as well as in Lubuntu session. Starting sound and logging out and in between any of these two sessions would mute the volume as shown. Starting the volume in one of these and logging out and then logging in into the Gnome session, the sound would be off; but then, after starting sound, logging out of Gnome and then logging in into any session, the sound would not be muted. But after restart it would be so no matter the session.

  • (rsErrorOpeningConnection) Could not obtain information about Windows NT group/user

    - by ChelleATL
    I am trying to deploy a report to the Reporting Services Server but keep running up against this error: An error occurred during client rendering. An error has occurred during report processing. (rsProcessingAborted) Cannot create a connection to data source 'dataSource1'. (rsErrorOpeningConnection) Could not obtain information about Windows NT group/user 'DOMAIN\useradmin', error code 0x5. Here’s my situation: Everything is being ran using DOMAIN\useradmin and the report is using a remote database. Reporting Services and SQL Server are both ran under DOMAIN\useradmin. DOMAIN\useradmin is a windows AD login and is part of the server machine Administrators group. My test report is using a data source model that in turn is using a data source that is connection to a database on a different SQL Server. The data source is using “Credentials stored securely in the report server” with the options “Use as Windows credentials when connecting to the data source” and “Impersonate the authenticated user after a connection has been made to the data source.” I am using the credentials of DOMAIN\useradmin that is the db owner of the remote database. DOMAIN\useradmin is assigned the roles, System Administrator, System User and Browser, Content Manager, My Reports, Publisher, Report Builder. So if everything is being run under an über AD account, why I am getting this Could not obtain information about Windows NT group/user 'DOMAIN\useradmin' error? Under normal circumstances , an AD login with Publisher permissions will developing reports using a datasource model created by DOMAIN\useradmin but using one of the remote database’s users which is mapped from yet another AD login. I ran the following statements and non errors were returned: use master go xp_grantlogin 'DOMAIN\useradmin' go xp_logininfo 'DOMAIN\useradmin' go

  • Slick2D + LWJGL collision system

    - by Connor W
    So I've been learning java for a while and have explored slick and lwjgl before but went away from using Slick for a while. But I've recently gone back to using it (as I'm making a platformer and Tiled will be really helpful). But here's where my problems begin: collision. I have a player polygon and I check to see if it's colliding with my tiled map with this method: public static boolean playerCollisionWith() { for(int i = 0; i < Blockmap.entities.size(); i++) { Block entity1 = (Block) Blockmap.entities.get(i); if(playerPoly.intersects(entity1.poly)) { return true; } } return false; } This would work normally but I'm using a different method for movement. Instead of just adding a speed variable to the player's x axis. I move like this: if(Keyboard.isKeyDown(Keyboard.KEY_RIGHT)) { speedX = Math.min(5, speedX + 1); moving = true; playerPoly.setX(x); if(playerCollisionWith()) { speedX = -5; playerPoly.setX(x); } } That Math.min call is what is messing me up =. I can't just call speedX = -5, because when I do the player "bounces" when the right mouse button is down and it's colliding. Bounces as in flashes back and forth REALLY quickly. But I don't really know how I would make it so that collisions on the y axis would work either, whether the player is jumping or not. So if I could get some help with how to fix this problem that would be great. Thank you for the help!

  • Database Design Question regaurding duplicate information.

    - by galford13x
    I have a database that contains a history of product sales. For example the following table CREATE TABLE SalesHistoryTable ( OrderID, // Order Number Unique to all orders ProductID, // Product ID can be used as a Key to look up product info in another table Price, // Price of the product per unit at the time of the order Quantity, // quantity of the product for the order Total, // total cost of the order for the product. (Price * Quantity) Date, // Date of the order StoreID, // The store that created the Order PRIMARY KEY(OrderID)); The table will eventually have millions of transactions. From this, profiles can be created for products in different geographical regions (based on the StoreID). Creating these profiles can be very time consuming as a database query. For example. SELECT ProductID, StoreID, SUM(Total) AS Total, SUM(Quantity) QTY, SUM(Total)/SUM(Quantity) AS AvgPrice FROM SalesHistoryTable GROUP BY ProductID, StoreID; The above query could be used to get the Information based on products for any particular store. You could then determine which store has sold the most, has made the most money, and on average sells for the most/least. This would be very costly to use as a normal query run anytime. What are some design descisions in order to allow these types of queries to run faster assuming storage size isn’t an issue. For example, I could create another Table with duplicate information. Store ID (Key), Product ID, TotalCost, QTY, AvgPrice And provide a trigger so that when a new order is received, the entry for that store is updated in a new table. The cost for the update is almost nothing. What should be considered when given the above scenario?

  • Hosting a WCF Service Lib through a Windows service get a System.InvalidOperationException: attempti

    - by JohnL
    I have a WCF Service Library containing five service contracts. The library is hosted through a Windows Service. Most if not all my configuration for the WCF Library is declaritive. The only thing I am doing in code for configuration is to pass the type of the class implementing the service contracts into ServiceHost. I then call Open on each of the services during the Windows Service OnStart event. Here is the error message I get: Service cannot be started. System.InvalidOperationException: Service '[Fubu.Conversion.Service1' has zero application (non-infrastructure) endpoints.

  • Rails and Mongoid best way to implement sharing system

    - by Matteo Pagliazzi
    I have to model User and Board in rails using mongoid as ODM. Each board is referenced to an user through a foreign key user_id and now I want to add the ability to share a board with other users. Following CRUD I'd create a new Model called something like Share and it's releated Controller with the ability to create/edit/delete a Share but I have some doubts: First, where to save informations about Shares? I think I may create a field in the Board's collection called shared_with including an array of user ids. in a MySQL I'd created a new table with the ids of who share, the resource shared and the user the resources is shared with but I don't think that's necessary using MongoDB. Every user a Board is shared with should be able to edit the Board (but not to delete it) so the Board should have two relations one with the owner and another with the users the board is shared with, right? For permission (the owner should be able to delete a board but the users it is shared with shouldn't) what to use? I'm using Devise for authentication but I think something like CanCan would fit better. but how to implement it? What do you think about this way? Do you find any problems or have better solutions?

  • Convert bitmap image information into CGImage in iPhone OS 3

I know all the color and alpha information to create the image, which stored in the matrix CML, but how can I do that?

  • System Wide Performance Sanity Check Procedures

    - by user702295
    Do you need to boost your overall implementation performance? Do you need a direction to pinpoint possible performance opportunities? Are you looking for a general performance guide? Try MOS note 69565.1.  This paper describes a holistic methodology that defines a systematic approach to resolve complex Application performance problems.  It has been successfully used on many critical accounts.  The 'end-to-end' tuning approach encompasses the client, network and database and has proven far more effective than isolated tuning exercises.  It has been used to define and measure targets to ensure success.  Even though it was checked for relevance on 13-Oct-2008, the procedure is still very valuable. Regards!

  • Where to find iPhone system buttons and icons graphics?

    - by Ariel
    Hey guys, I'm trying to find a way to use the original Apple system buttons and icons in a web site. Is there a way to get these original graphics in png format? There are not-so-nice ways to obtain them of course. Two I was thinking of: Save them from this link, then convert to png. Take screen captures on the iPhone itself, and cut the icons from the saved images. Is anyone aware of a nicer way to obtain the original graphics? Does anyone know where they are stored on the Mac? Thanks :-) Ariel

  • C library build system dependencies

    - by Ninefingers
    Hello all, This debate has cropped up on a mailing list for a project I'm involved in. Unfortunately we're quite a small bunch at the moment, so I want to ask a wider audience. We're writing a C library (for arbitrary precision arithmetic) and are investigating build systems. Currently we have a bash script in desperate need of work. I believe we can't use autotools etc due to licensing (bsd vs gpl). So I suggested we use a modern scripting language like python or perl. The question is: is having something like perl or python around at build time an unrealistic dependency on Unix-like platforms these days?

  • IVR-style dialog system / workflow / menu

    - by unbeli
    I need to build a dialog system similar to IVR used in call centers. My system is not phone-based, but the dialog is similar. Something like System: "Main menu: Enter [1] for menu1, [2] for menu2" User: [1] System: "menu1: enter [1] for apples, [2] for oranges, [3] for main menu" User: [7] System: "What??" System: "menu1: enter [1] for apples, [2] for oranges, [3] for main menu" User: [2] ... and so on I want to have a nice declarative description of all the possible options and a nice way to run through that tree, guided by user input. Already considered: ANTLR-generated lexer/parser (seems to be an overkill), SCXML-based state machine (seems like only transitions can be declared, the rest needs to be coded)

  • Developing a php system that tracks other websites analytics

    - by CodeCrack
    I want to develop a PHP website feature where users sign up, get a javascript snippet code that display an image on their site, and let's me track the number of visitors, unique hits, clicks and average visitor duration on their page. Is that something that should be done with some open source analytic software such as http://piwik.org/ or it's pretty doable on your own? If I had to do it myself from scratch, I would use image/pixel as a way to track the visit, drop a cookie with javascript snippet to track uniques, track clicks based on image click and redirect, and not sure about the bounce rate. Any thoughts or opinions are welcome.

  • Cannot boot into system after deleting partition

    - by Clayton
    Okay...so this was kind of a stupid thing for me to do now that I think back on it. I was experiencing a ton of lag and not as much memory that I could use after installing Ubuntu 12.04. So after remembering I had installed multiple server versions of Ubuntu 12.04 by mistake, I went into Disk Management and proceeded to delete each and every one. Everything went fine. Up until this week, I have not experienced any problems. But starting yesterday I began to get lag just as I had before, and nothing fixed the problem. I decided to remove the Ubuntu partition, since I was also experiencing a visual error when given the option to select one to boot(the screen doesn't come up at all, and I recieved a monitor resolution error instead, but could still access both Windows and Ubuntu via arrow keys). After deleting the Ubuntu partition, so that I could see if running just Windows would fix the problem, I proceeded with what I was doing, installing a few programs that were not tied to my prediciment in any way. Upon rebooting my desktop, however, I recieved the following error: error: unknown filesystem. grub rescue> Hoping I could boot into Ubuntu via a pendrive and possibly backup my important files and wipe the hard drive to start fresh, I installed Ubuntu 13.04, but even that does not boot. Instead, I get this message on a terminal screen: SYSLINUX 4.06. EDD 4.06-pre1 Copyright (C) 1994-2011 H. Peter Anvin et al ERROR: No configuration file found No DEFAULT or UI configuration directive found! boot: So more or less, my desktop is screwed. I need to be able to get to the files inside because of my job as an artist, as well as retrieve my documents for my stories stored on Windows. Once I can succeed in solving this once and for all, I know for a fact I will stick to Ubuntu only, and install what is required to be able to run any Windows applications I used to use or need to use. I would rather not reformat the hard drive, and if I need to, it is a last resort. And I doubt I can use a Windows Recovery Disk to get my files back, as my mom has thrown out a lot of the installation disks and paperwork I would need to even follow through with that. :\ Keep in mind that I am a novice/newbie when it comes to Linux, but am hoping ot become better at it as time goes by. I appreciate any help you guys can give me. This will probably be the last time I attempt to do anything that could risk the well-being of my PC. (I've also looked through various questions on the site and tested a lot of the solutions. None seem to have worked.)
