I'm using stackprof to profile a sinatra application which uses Active Record. When I inspect the output of the generated files, I get the following:
[vagrant#localhost vagrant]$ bin/stackprof tmp/stackprof-cpu-5754-1468440335.dump --text --limit 10

When I subscribe and log the notifications, they are simply AR query notifications, which I don't care about at the moment.
It also appears that ActiveSupport::Subscribers / notifications are a performance bottleneck. Is there a way to disable turn these via an ActiveSupport configuration?

I have generated a dxf file but when I opened it with AutoCAD, crashes AutoCAD and gives a message ID 11 incorrect: already used.
the dxf content: https://github.com/tarikjabiri/dxf/blob/dev/examples/latest.dxf
I can't spot the problem 3 days I am trying to solve it.
I think something wrong with the APPID because it holding the ID 11 or the Handle in the language of DXF.
I have a dxf working: https://github.com/tarikjabiri/dxf/blob/dev/examples/Minimal_DXF_AC1021.dxf
Thanks in advance.

Somewhere in your source, usually at the root of a particular component's html/xml, you have a view that is only rendered on iOS. However, because it fails on iOS and not Android, it is likely that you have not placed the similar restriction on the other top-level element.
<ios>
<Label text="only iOS"></Label>
</ios>
<Label text="only Android"></Label> <!-- Error; is present in template for both!! -->
It is hard for me to guess where exactly the issue might be, but I'd suggest having a look through your templates for the usage of ios.
Well in ios u cant have free templates floating arround everything was too be inside a LayoutContainer

I have a situation where each Order can have Feedback. In case the product is physical, the Feedback can have many packaging_feedbacks. The packaging_feedbacks are supposed to be a relation to the packaging_feedback_details.
Feedback Model
public function packagingFeedbacks()
{
return $this->hasManyThrough('App\PackagingFeedbackDetail', 'App\PackagingFeedback',
'feedback_id', 'id', 'id', 'user_selection');
}
packaging_feedback_details
id|type_id(used to group the "names" for each feedback option)|name
1 0 well packed
2 0 bad packaging
3 1 fast shipping
4 1 express delivery
packaging_feedbacks
id|feedback_id|user_selection (pointing to the ID of packaging_feedback_details)
1 1 2
2 1 6
3 1 7
4 1 12
5 1 15
6 1 17
7 2 1
8 2 6
9 2 7
10 2 12
11 2 15
12 2 17
13 3 1
14 3 6
15 3 7
16 3 12
17 3 15
18 3 17
Now I would like to be able to get the average selection of the users for a physical product. I started by using:
$result = Product::with('userFeedbacks.packagingFeedbacks')->where('id', 1)->first();
$collection = collect();
foreach ($result->userFeedbacks as $key) {
foreach ($key->packagingFeedbacks as $skey) {
$collection->push($skey);
}
}
foreach ($collection->groupBy('type_id') as $key) {
echo($key->average('type_id'));
}
But it returns not the average id since it will calculate the average not the way I need it to calculate. Is there some better way, because I think it's not the cleverest way to do so. Is my database design, in general, the "best" way to handle this?
The type of average you're looking for here is mode. Laravel's collection instances have a mode() method which was introduced in 5.2 which when provide a key returns an array containing the highest occurring value for that key.
If I have understood your question correctly this should give you what you're after:
$result->userFeedbacks
->flatMap->packagingFeedbacks
->groupBy('type_id')
->map->mode('id');
The above is taking advantage of flatMap() and higher order messages() on collections.
I recently started learning Hadoop,
I found this data set http://stat-computing.org/dataexpo/2009/the-data.html - (2009 data),
I want some suggestions as what type of patterns or analysis can I do in Hadoop MapReduce, i just need something to get started with, If anyone has a better data set link which I can use for learning, help me here.
The attributes are as:
1 Year 1987-2008
2 Month 1-12
3 DayofMonth 1-31
4 DayOfWeek 1 (Monday) - 7 (Sunday)
5 DepTime actual departure time (local, hhmm)
6 CRSDepTime scheduled departure time (local, hhmm)
7 ArrTime actual arrival time (local, hhmm)
8 CRSArrTime scheduled arrival time (local, hhmm)
9 UniqueCarrier unique carrier code
10 FlightNum flight number
11 TailNum plane tail number
12 ActualElapsedTime in minutes
13 CRSElapsedTime in minutes
14 AirTime in minutes
15 ArrDelay arrival delay, in minutes
16 DepDelay departure delay, in minutes
17 Origin origin IATA airport code
18 Dest destination IATA airport code
19 Distance in miles
20 TaxiIn taxi in time, in minutes
21 TaxiOut taxi out time in minutes
22 Cancelled was the flight cancelled?
23 CancellationCode reason for cancellation (A = carrier, B = weather, C = NAS, D = security)
24 Diverted 1 = yes, 0 = no
25 CarrierDelay in minutes
26 WeatherDelay in minutes
27 NASDelay in minutes
28 SecurityDelay in minutes
29 LateAircraftDelay in minutes
Thanks
