  • Is Tracking Software Usage Illegal?

    - by Graviton
    Let's say if I am doing desktop application, and I am interested to know whether our software really gets used or not. Is it alright to insert in code that tracks whether our software is used, for how long and so on? Note that no person-identifiable information will be collected, all I am interested to know is how frequent and for how long the software is used. The information will be sent to our server for diagnosis. What do you think?

  • Displaying performance data per engine subsystem

    - by liortal
    Our game (Android based) traces how long it takes to do the world logic updates, and how long it takes to a render a frame to the device screen. These traces are collected every frame, and displayed at a constant interval (currently every 1 second). I've seen games where on-screen data of various engine subsystems is displayed, with the time they consume (either in text) or as horizontal colored bars. I am wondering how to implement such a feature?

  • Secret of SQL Trace Duration Column

    - by Dan Guzman
    Why would a trace of long-running queries not show all queries that exceeded the specified duration filter?  We have a server-side SQL Trace that includes RPC:Completed and SQL:BatchCompleted events with a filter on Duration >= 100000.  Nearly all of the queries on this busy OLTP server run in under this 100 millisecond threshold so any that appear in the trace are candidates for root cause analysis and/or performance tuning opportunities. After an application experienced query timeouts, the DBA looked at the trace data to corroborate the problem.  Surprisingly, he found no long-running queries in the trace from the application that experienced the timeouts even though the application’s error log clearly showed detail of the problem (query text, duration, start time, etc.).  The trace did show, however, that there were hundreds of other long-running queries from different applications during the problem timeframe.  We later determined those queries were blocked by a large UPDATE query against a critical table that was inadvertently run during this busy period. So why didn’t the trace include all of the long-running queries?  The reason is because the SQL Trace event duration doesn’t include the time a request was queued while awaiting a worker thread.  Remember that the server was under considerable stress at the time due to the severe blocking episode.  Most of the worker threads were in use by blocked queries and new requests were queued awaiting a worker to free up (a DMV query on the DAC connection will show this queuing: “SELECT scheduler_id, work_queue_count FROM sys.dm_os_schedulers;”).  Technically, those queued requests had not started.  As worker threads became available, queries were dequeued and completed quickly.  These weren’t included in the trace because the duration was under the 100ms duration filter.  The duration reflected the time it took to actually run the query but didn’t include the time queued waiting for a worker thread. The important point here is that duration is not end-to-end response time.  Duration of RPC:Completed and SQL:BatchCompleted events doesn’t include time before a worker thread is assigned nor does it include the time required to return the last result buffer to the client.  In other words, duration only includes time after the worker thread is assigned until the last buffer is filled.  But be aware that duration does include the time need to return intermediate result set buffers back to the client, which is a factor when large query results are returned.  Clients that are slow in consuming results sets can increase the duration value reported by the trace “completed” events.

  • How do I make this rendering thread run together with the main one?

    - by funk
    I'm developing an Android game and need to show an animation of an exploding bomb. It's a spritesheet with 1 row and 13 different images. Each image should be displayed in sequence, 200 ms apart. There is one Thread running for the entire game: package com.android.testgame; import android.graphics.Canvas; public class GameLoopThread extends Thread { static final long FPS = 10; // 10 Frames per Second private final GameView view; private boolean running = false; public GameLoopThread(GameView view) { this.view = view; } public void setRunning(boolean run) { running = run; } @Override public void run() { long ticksPS = 1000 / FPS; long startTime; long sleepTime; while (running) { Canvas c = null; startTime = System.currentTimeMillis(); try { c = view.getHolder().lockCanvas(); synchronized (view.getHolder()) { view.onDraw(c); } } finally { if (c != null) { view.getHolder().unlockCanvasAndPost(c); } } sleepTime = ticksPS - (System.currentTimeMillis() - startTime); try { if (sleepTime > 0) { sleep(sleepTime); } else { sleep(10); } } catch (Exception e) {} } } } As far as I know I would have to create a second Thread for the bomb. package com.android.testgame; import android.graphics.Bitmap; import android.graphics.Canvas; import android.graphics.Rect; public class Bomb { private final Bitmap bmp; private final int width; private final int height; private int currentFrame = 0; private static final int BMPROWS = 1; private static final int BMPCOLUMNS = 13; private int x = 0; private int y = 0; public Bomb(GameView gameView, Bitmap bmp) { this.width = bmp.getWidth() / BMPCOLUMNS; this.height = bmp.getHeight() / BMPROWS; this.bmp = bmp; x = 250; y = 250; } private void update() { currentFrame++; new BombThread().start(); } public void onDraw(Canvas canvas) { update(); int srcX = currentFrame * width; int srcY = height; Rect src = new Rect(srcX, srcY, srcX + width, srcY + height); Rect dst = new Rect(x, y, x + width, y + height); canvas.drawBitmap(bmp, src, dst, null); } class BombThread extends Thread { @Override public void run() { try { sleep(200); } catch(InterruptedException e){ } } } } The Threads would then have to run simultaneously. How do I do this?

    OTN Architect Day - Boston - Sept 12: What to Expect If you've never attended an OTN Architect Day, here's a little preview. You start with a continental breakfast. Then you have keynotes by an Oracle expert, and a member of the Oracle ACE community. After that come the break-out sessions, so you have your choice of two sessions in each time slot. So you'll get in two breakouts before lunch. Then you eat. After that there's a panel Q&A during which the audience tosses questions at the assembled session speakers. Then it's on to another set of break-out sessions, followed by a short break. Then the audience breaks into small groups for round table discussions. After that there's a drawing for some cool prizes, followed by the cocktail reception. All that costs you absolutely zero. Register now.

    Possible Duplicate: What are some good tools for introducing kids to programming? Long-long time ago I had a great book by Frank DaCosta about writing adventure games in Basic, it had a great influence on me. I would like to show the world of programming to my child too but I have two problems: I can not found books like DaCosta's (but we can replace it with our fantasy so not a big deal) Which programming language should I use?

  • Toshiba wireless is blocked

    I have the same problem, a 32 bits toshiba nb255, it first had the windows 7 bu next I installed the ubuntu 11.04. The wifi does not turn on. I used the following issues the commands rfkill unblock wlan0, sudo ifconfig wlan0 down; they were not able. by setting up the bios in advanced menu, the wireless communication sw in ON, but it did not work also. neither the utilities toshiba nor utilities of ubuntu (wicd, wifi radar). by using gedit to file group, nothing. by installing madwifi packet, nothing. by exporting the wifi driver from windows to ubuntu, by means of the NDISwrapper packet, neither.

Toshiba does not supply drivers or soft support for linux, marketing of course. I only see the device is up by protocols and down phisically, My question is, is it possible to enable or not shutdown physically the device?, because in the toshiba model nb255 the wifi is not set up/down bye means of a physical switch, but by means a combination of Fn + F8 (only for windows 7, no one more), Is there one possibility to configure the hot keys in ubuntu?
