  • Getting the location in Android programatically

    - by steveo225
    I know this has been asked a ton, so my apologies. I have the following code, and cannot get the location, always a null response. I am trying to avoid a LocationListener in this instance because I am already using an update Service, and the location really doesn't have to be that fine, so the last known location is good enough. Thanks for the help. LocationManager lm = (LocationManager)getSystemService(Context.LOCATION_SERVICE); String providers[] = {"gps", "network", "passive"}; Location loc = null; for(String x : providers) { loc = lm.getLastKnownLocation(x); if(loc != null) break; } if(loc != null) { // do something, never reached }

  • Is there a cap on the number of modules WinDbg can see?

    - by Bethor
    Does anyone know if there is a cap on the number of DLLs WinDbg can see ? I believe Visual Studio was once capped at 500 but I can't find a source for this claim outside of some second hand accounts at work. I'm trying to debug a hairy scenario and WinDbg's stack trace is incomplete. According to Process Explorer, the module I'm interested in is loaded but it doesn't show up in the output of 'lm' in WinDbg. Suspiciously, said output is exactly 500 modules long, even though I know there are many more than that loaded, leading me to believe WinDbg isn't seeing DLLs beyond the first 500. Can anyone confirm ? Or suggest some other reason why a loaded module might not show up in 'lm' ?

  • Data frame linear fit in R

    - by user1247384
    This is perhaps a simple question, but I am n00b.Say I have a data frame with a bunch of columns. I need to call lm function over the column 1 and 2, 1 and 3, and so on. So basically I need to loop over all columns and store the results of the fit as I build the model. The problem I am running into is that lm(df[1]~df[2], data = df) doesnt work. In this case df is the data frame object and df[1] is the first column. What is a good way to do this in a loop, as in access the columns of df in an iterative fashion. Thanks.

  • Anova test in the loop and outputing the p-value in separate column

    - by Juanhijuan
    Once again I'm trying to get an answer. I am already stuck for like 5h with that so that's why I keep trying to get an answer. That's my data: id Sequence variable value 75 AAAAGAAAVANQGKK BiotinControl1_2 3893050.50 192 AAAAGAAAVANQGKK BiotinControl1_2 900604.61 3770 AAFTKLDQVWGSE BiotinControl1_2 90008.14 The code which I am trying to use to calculate the p-value: My Code: tbl_anv <- tbl_all_onlyK[,c("id", "BiotinControl1_2", "BiotinControl2", "BiotinControl3", "BiotinTreatment1_2", "BiotinTreatment2", "BiotinTreatment3", "Sequence")] tbl_reo <- melt(tbl_anv, measure.vars=2:7) set.seed(1) vars <- c("id", "BiotinControl1_2", "BiotinControl2", "BiotinControl3", "BiotinTreatment1_2", "BiotinTreatment2", "BiotinTreatment3", "Sequence") tbl_reo <- as.data.frame(tbl_reo) by(tbl_reo,tbl_reo$Sequence,function(x){ anova(lm(value ~ variable, data = x))$"Pr(>F)"[1] }) An error ocurs: There were 50 or more warnings (use warnings() to see the first 50) Anyway, how can I do that and export the p-value in the separate column. That's what I tried to do on my own: aov_test <- by(tbl_reo,tbl_reo$Sequence,function(x){ anova(lm(value ~ variable, data = x))$"Pr(>F)"[1] }) tbl_reo[,5] <- aov.test[[1]]$'Pr(>F)'[1]

  • What's wrong with this addProximity code?

    - by Pentium10
    I have this code: private void setupProximity() { Intent intent = new Intent(this, viewContacts.class); PendingIntent sender = PendingIntent.getBroadcast(this, 0, intent, 0); LocationUtils.addProximity(this, -37.40, 144.55, 1000, 1000000, sender); } public static void addProximity(Context ctx,double lat, double lon, float rad,long exp, PendingIntent pintent) { LocationManager lm = (LocationManager) ctx.getSystemService(Context.LOCATION_SERVICE); lm.addProximityAlert(lat, lon, rad, exp, pintent); } Why I don't get the class to fire up? I am in the range of the zone.

  • C++ - Where to code a member function for an inherited object.

    - by Francisco P.
    Hello! I have a few classes (heat, gas, contact, pressure) inheriting from a main one (sensor). I have a need to store them in a vector<Sensor *> (part of the specification). At some point in time, I need to call a function that indiscriminately stores those Sensor *. (also part of the specification, not open for discussion) Something like this: for(size_t i = 0; i < Sensors.size(); ++i) Sensors[i]->storeSensor(os) //os is an ofstream kind of object, passed onwards by reference Where and how shall storeSensor be defined? Is there any simple way to do this or will I need to disregard the specification? Mind you, I'm a beginner! Thanks for your time!

  • Getting back from security & location to my application

    - by sandman42
    Hi, I have an application that allows the user to enable GPS. In order to do it, first in the main activity I do: lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE); if (!lm.isProviderEnabled(LocationManager.GPS_PROVIDER)){ showGpsOptions(); } showGpsOptions() is: private void showGpsOptions() { Intent gpsOptionsIntent = new Intent(android.provider.Settings.ACTION_LOCATION_SOURCE_SETTINGS); startActivityForResult(gpsOptionsIntent, BACK_FROM_GPS_ACT); } and finally I override main activity onActivityResult in this way: protected void onActivityResult(int requestCode, int resultCode, Intent data) { if (requestCode == BACK_FROM_GPS_ACT){ ; } super.onActivityResult(requestCode, resultCode, data); } Problem: the page show up and works, but when I press back I get back to home screen. Question: how can I get back to my application? Thanks a lot

  • Is it a header file or library? in a makefile

    - by gccinac
    I already know the differences between a header file and a library. However, when I'm writing my makefile, I have some difficulties on deciding if I should put something as a dependency of the file or just at the linking rule. For example: I have 2 simple files: main.c: #include <stdio.h> main(){ printf("this is the sine or 90"); sinus(90); } and func.c: #include <math.h> sinus(int num){ return sin(num); } and my makefile is: main: main.o func.o gcc main.o func.o -lm -o main func.o: func.c main.o: main.c Well, my question is why this makefile works and this one doesn't: main: main.o func.o gcc main.o func.o -lm -o main func.o: func.c math.h main.o: main.c

  • What does the R function `poly` really do?

    - by merlin2011
    I have read through the manual page ?poly (which I admit I did not completely comphrehend) and also read the description of the function in book Introduction to Statistical Learning. My current understanding is that a call to poly(horsepower, 2) should be equivalent to writing horsepower + I(horsepower^2). However, this seems to be contradicted by the output of the following code. library(ISLR) summary(lm(mpg~poly(horsepower,2), data=Auto))$coef summary(lm(mpg~horsepower+I(horsepower^2), data=Auto))$coef Output: Estimate Std. Error t value Pr(>|t|) (Intercept) 23.44592 0.2209163 106.13030 2.752212e-289 poly(horsepower, 2)1 -120.13774 4.3739206 -27.46683 4.169400e-93 poly(horsepower, 2)2 44.08953 4.3739206 10.08009 2.196340e-21 Estimate Std.

  • How does getAltitude() of Android GPS Location Works

    - by Sebi
    HI I tried to implement a simple GPS tracker. Therefore is used lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE); lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 1000, 0, this); Then i used the public void onLocationChanged(Location location) { method to read the altitude of my current location. But i dont really know what Location.getAltitude() returns. The document says it returns the altitude. But is this in meters? or feets? if i put the phone on the desk next to me, this value changes between 500 and -500?? How does this really work???

  • BAM design pointers

    - by Kavitha Srinivasan
    In working recently with a large Oracle customer on SOA and BAM, I discovered that some BAM best practices are not quite well known as I had always assumed ! There is a doc bug out to formally incorporate those learnings but here are a few notes..  EMS-DO parity When using EMS (Enterprise Message Source) as a BAM feed, the best practice is to use one EMS to write to one Data Object. There is a possibility of collisions and duplicates when multiple EMS write to the same row of a DO at the same time. This customer had 17 EMS writing to one DO at the same time. Every sensor in their BPEL process writes to one topic but the Topic was read by 1 EMS corresponding to one sensor. They then used XSL within BAM to transform the payload into the BAM DO format. And hence for a given BPEL instance, 17 sensors fired, populated 1 JMS topic, was consumed by 17 EMS which in turn wrote to 1 DataObject.(You can image what would happen for later versions of the application that needs to send more information to BAM !).  We modified their design to use one Master XSL based on sensorname for all sensors relating to a DO- say Data Object 'Orders' and were able to thus reduce the 17 EMS to 1 with a master XSL. For those of you wondering about how squeaky clean this design is, you are right ! This is indeed not squeaky clean and that brings us to yet another 'inferred' best practice. (I try very hard not to state the obvious in my blogs with the hope that everytime I blog, it is very useful but this one is an exception.) Transformations and Calculations It is optimal to do transformations within an engine like BPEL. Not only does this provide modelling ease with a nice GUI XSL mapper in JDeveloper, the XSL engine in BPEL is quite efficient at runtime as well. And so, doing XSL transformations in BAM is not quite prudent.  The same is true for any non-trivial calculations as well. It is best to do all transformations,calcuations and sanitize the data in a BPEL or like layer and then send this to BAM (via JMS, WS etc.) This then delegates simply the function of report rendering and mechanics of real-time reporting to the Oracle BAM reporting tool which it is most suited to do. All nulls are not created equal Here is yet another possibly known fact but reiterated here. For an EMS with an Upsert operation: a) If Empty tags or tags with no value are sent like <Tag1/> or <Tag1></Tag1>, the DO will be overwritten with --null-- b) If Empty tags are suppressed ie not generated at all, the corresponding DO field will NOT be overwritten. The field will have whatever value existed previously.  For an EMS with an Insert operation, both tags with an empty value and no tags result in –null-- being written to the DO. Hope this helps .. Happy 4th!

  • Cannot get Virtualbox to install properly on Ubuntu 12.04

    - by lopac1029
    I cannot get Virtualbox to install properly on my 12.04. I first went with a manual install for the .deb from the old builds section of the Virtualbox page. That .deb opened up the Software Center and installed. Then I got the error coming up of VT-x/AMD-V hardware acceleration is not available on your system. Your 64-bit guest will fail to detect a 64-bit CPU and will not be able to boot. which I can only assume was due to my Ubuntu version being 32-bit (System Details - Overview - OC type: 32-bit, right?) So I followed these instructions to remove the .deb manually, restarted my laptop, and then FOUND the actual Virtualbox install in the Software Center and installed from that (assuming it would give me the correct version I need for my system) So after all that (and then some), I'm still getting the same error when I connect to my new job's project in Virtualbox. Can anyone point me in the right direction of what to do here? This is the first time I've ever worked with Virtualbox, and no one at this company is using Ubuntu, so I'm on my own here.

  • overheating and shutdown problems when adobe flash runs?

    - by hamid
    I'm a new user of UBUNTU and using a Dell latitude D630. When I browse to site that have some flash animation (mostly advertisements), the temperature of cores increase dramatically (I check with sensors, in the worse case it was 104C for one core and 93 for the other core) and if I don't close the website it will shutdown the laptop. Do you have any suggestion or solution for that? PS: as an example for crashing sites you can see "tabnak.ir", a news website with lots of ads.

  • Macbook Pro 2011 compatibility

    - by ldx
    Hi there, I'm planning to a buy a new 13" Macbook Pro, the one that was just released this week with the Thunderbolt port. The question is, has anyone given it a shot with Ubuntu (10.10 or 11.04 alpha)? I'd be especially interested whether temperature sensors/fan control, external displays via the displayport and 3D acceleration (for Compiz or some simple 3D games) via the integrated HD3000 GPU work without flaws. Thanks!

  • How to have an Arduino wait until it receives data over serial?

    - by SonicDH
    So I've wired up a little robot with a sound shield and some sensors. I'm trying to write a sketch that will let check the sensors. What I'd like for it to do is print out a little menu over serial, wait until the user sends a selection, jump to the function that matches their selection, then (once the function is done) jump back and print the menu again. Here's what I've written, but I'm not a that good of a coder, so it doesn't work. Where am I going wrong? #include <Servo.h> Servo steering; Servo throttle; int pos = 0; int val = 0; void setup(){   Serial.begin(9600);   throttle.write(90);   steering.write(90);   pinMode(A0, INPUT);   pinMode(7, INPUT);   char ch = 0; } void loop(){   Serial.println("Menu");   Serial.println("--------------------");   Serial.println("1. Motion Readout");   Serial.println("2. Distance Readout");   Serial.println("3. SD Directory Listing");   Serial.println("4. Sound Test");   Serial.println("5. Car Test");   Serial.println("--------------------");   Serial.println("Type the number and press enter");   while(char ch = 0){   ch = Serial.read();}   char ch;   switch(ch)   {     case '1':     motion();   }    ch = 0; } //menu over, lets get to work. void motion(){   Serial.println("Haha, it works!"); } I'm pretty sure a While loop is the right thing to do, but I'm probably implementing it wrong. Can anyone shed some light on this?

  • Why does cpuinfo report that my frequency is slower?

    - by Avery Chan
    My machine is running off of a AMD Sempron(tm) X2 190 Processor. According the marketing copy, it should be running at around 2.5 Ghz. Why is the cpu speed being reported as something lower?

  • Dell Inspiron 1564 overheating but fan not switching on, how to diagnose?

    - by Smugrik
    I've got a Dell Inspiron 1564 laptop that is about one and a half years old. Since about a week, the laptop started to overheat, causing it to switch off unexpectedly... The cpu fan is working erratically, it can start to spin for a while, doing its job and cooling down the cpu before it stops, but then the temperature goes up, and the fan doesn't reacts, once the temperature reaches a critical point (over 85 celsius, checked with speedfan...), the laptop switches off... I already cleaned the vents and fan from dust, to no avail, and it was actually quite clean anyway. Drivers and bios are up-to-date, no crapware was ever installed on this machine. I don't know how to diagnose the problem, could it be the temperature sensors that sends wrong information, so the fan doesn't reacts? but then I believe the computer wouldn't detect the overheat and stop... Is there a way I can pin point the problem? Maybe some low-level diagnostic tools to check functionality of sensors and fans??? The warranty is already over so any suggestion would be welcome. Thanks!!
