35mm – Point and shoot advancer unwinding film

I'm new to filming cameras and recently bought my first camera for close-up shots. It worked great until somebody opened the movie box without knowing that he should not. The camera is fully automatic, so the film continues to move after the tray is closed. It ended up with the entire roll of film being wound up, and always when I put in a new roll of film. The camera shoots perfectly without film, but does not work when a movie is inserted. When a movie is loaded, the camera does not register it correctly and displays "0" as the exposure number. Everything works fine as long as no movie is loaded, and I hate wasting film when I know that it will only be unwound once it's loaded. Any ideas?

Reference Request – Geometric morphism whose point of view is epic

Is there a name for the class of geometric morphisms whose contours are epic (corresponding to which direct images are faithful)?

This includes in particular the class of inclusions / embeds of toposes. By example A4.6.2 in Johnstone Sketches of an elephant: A Topos Theory CompendiumAll of these morphisms are local, but since Johnstone does not have a name there (and his cross-references are generally very thorough), I assume they are not self-contained in the text.

If no one can dig up a reference, I would like to say so injection as a name for this property, not only because fidelity gives injectivity to hom sets, but also because this is the conceptual dual of a geometric surjection that has a monistic unity / an exact inverse image.

Log / View remote calls / queries to the database in Toad Data Point

I'm running an Apache Sqoop job from a local machine against an Oracle database that we're connected to through a virtual tunnel, and we notice that the process on certain large sqoop jobs after completing a certain X% method Keeps hanging. I want to see exactly what queries are sent and read from the database to Toad Data Point (the interface that is normally used to manually run queries against the remote database). Does anyone know how to do that?

$ EN cap FM = X $ and $ EC cap FB = Y $. Prove that $ XY $ goes through a fixed point.

$ E $ and $ F $ are points each on segments $ AB $ and $ AC $ so that $ EF parallel BC $, The tangents of $ (AEF) $ at points $ E $ and $ F $ cuts $ BC $ resepctively $ M $ and $ N $, $ EN cap FM = X $ and $ EC cap FB = Y $, Prove that $ XY $ goes through a fixed point.

Enter image description here

I have a prediction in which $ XY $ cuts $ BC $ at the fixed point $ D $, Maybe where $$ dfrac {DM} {DB} left (= dfrac {DX} {DY} right) = dfrac {DN} {DC} $$, But I'm unsure.

linux – Amazon S3 Bucket Mount Point is automatically removed

I use s3fs on an aws Ubuntu instance to mount s3 bucket. It follows the command with which I have mounted the spoon.

sudo fusermount -u /s3/project1
sudo s3fs -o allow_other project1 /s3/project1  

The machines will never be restarted. Often, however, this mount came off. And while I access the mount, I get the following error message.

can not access & # 39; / s3 / project1 & # 39; access: transport endpoint is not connected

How is it fixed permanently?

8 – Why was my code overwritten from my point of view "Use replacement tokens from first line"?

In Drupal 8, I'll create two view blocks with a header containing the following code (Global: text area):

  

When I activate the tokens, the buttons in my view are overridden:

Enter image description here

If I want to disable the tokens, the buttons in my view will work as follows:

Enter image description here

Why did I override my code in my opinion using "substitute tokens from the first line"?

All lines containing the code disappear when the tokens are activated.

Algorithm for point classification out of range

I have a device that sends its coordinates every 30 seconds. When I get the coordinates, I classify the point either as belonging to a predefined area (ie, inside it) (so I assign it an area number> 0) or as an "external" point (specified by area – 1).

External points can be caused essentially for two reasons:

1) The device is moving and is currently between two areas. So if you are moving from area 100 in area 78, a sequence like 100, … 100, -1, -1, …, -1, 78 will be displayed. 78, 78 … The sequence of -1 is longer or shorter depending on the distance between the two sections and the device speed.

2) The device is located near an area boundary. Due to the limited accuracy of the device's GPS signal, it may sometimes appear that the device is entering and exiting the area. So it's about 99, -1, 99, 99, -. 1, -1, 99, 99 … until finally it returns to a constant run of 99 as the device moves back into the range (or into another range, in this case we have Case 1).

At the end of the day, I have a list of entries (timestamp, coordinates, area) (approximately 2500 points, which include an unknown number of ranges, depending on how the device moved during the day).

Now I have to classify external points (area == -1) and assign them to a real area. For example, for case 1), half (more or less) of -1 should be assigned to area 100, the other half to area 78, while for case 2) all -1 should be assigned to area 99.
Of course, this reclassification is done when the full data is available for the day, not in real time.

I just need an introduction to tackle the problem or the existing algorithms that perform this task, and then I'll do my research. Thank you very much.

c ++ – Check if it is possible to get to a point represented by a number

The problem is to see if we can move horizontally and vertically to a wall that is represented by a number or not. If we can, print one of the correct answers and we can not print -1.

We have three entrances. The first is the distance to the wall (s). The second is our foot length (x) and the third is our foot width (y).

1 ≤ n, x, y ≤ 100 000

I wrote a code for it and it's almost right, I think. I want an optimized and faster solution.
