QUESTION
Is there a thread-safe reference counter class in the standard C++ library, (or as an extension in Visual Studio), or would I need to write this kind of object from scratch?
I'm hoping for an object that purely performs reference counting as shared_ptr
might, with the exception that it does so across multiple threads accurately, and without managing anything. shared_ptr
and it's cousin structures are nice because they define all the copy constructors and assignment operators you'd need, which ... are the most error prone part of C++ to me; C++ Constructors are to C++ what the Kick-off is to American Football.
ANSWER
Answered 2021-Aug-26 at 10:22The warnings about thread safety w.r.t. std::shared_ptr
are
- If you have multiple threads that can access the same pointer object, then you can have a data race if one of those threads modifies the pointer. If each thread has it's own instance, pointing to the same shared state, there are no data races on the shared state.
- The final modification of the pointed-to object on a thread does not inter-thread happens before another thread observing a
use_count
of 1. If nothing is modifying the pointed-to object, there are no data races on the pointed-to object.

I've created a multi-sheet workbook that has Manifest Data (Sheet1), Sammy (Sheet2), Trev (sheet3), Scan Data In (Sheet4). On each of the worksheets is a column labeled Connote and the data within cells of the column relates to a barcode on the paperwork we use. When I open a drivers worksheet i will scan the barcode from the paperwork and information will be pulled from the Manifest Sheet as well Time/Date Stamping using VBA. But what I'm trying to do is pull the drivers name which is in a cell on their worksheet back to the Manifest Data sheet which relates to the connote they have just scanned. I'm happy to upload the working sheet if required. Manifest Data Sheet Drivers Sheet https://1drv.ms/x/s!AiXQNwMzQ3OrnCxn4D54gpnBH9V0?e=fxsTnz

I thought I had everything covered, but I'm now having issues with flip boxes working on Mac. I was able to make them compatible with different browsers on phones. I had someone with a Mac say that they were having problems with the animation. I heard that they saw a weird blinking and can see the front of the card through the back. I'm not sure what I'm missing. The last time I had this issue was with iOS, but I was just missing one line of code. Any suggestions? Honestly, I'm winging this as I go and can use any guidance.

QUESTION
I don't really have any background of HTML or CSS. I've been figuring out how to change existing codes to help make sections of a website. The only issue is that I can't make it mobile-friendly. I made a code to create 8 flip boxes that work when you visit the website on a computer. However, they don't work so well on mobile. I don't really know what I'm doing, but is there anyway I can align the 8 boxes in one column for mobile use and use touch to make them flip? Thanks!
...ANSWER
Answered 2021-Apr-28 at 00:33For making it responsive to mobile use media queries: https://www.w3schools.com/css/css_rwd_mediaqueries.asp
Also, hover on mobile acts like a touch input so I don't think you have a problem with that

I'm trying to understand and implement a research work on Triple Attention Learning, which consists on
...ANSWER
Answered 2021-Mar-02 at 00:56When paper introduce they method they said:
The attention modules aim to exploit the relationship between disease labels and (1) diagnosis-specific feature channels, (2) diagnosis-specific locations on images (i.e. the regions of thoracic abnormalities), and (3) diagnosis-specific scales of the feature maps.
(1), (2), (3) corresponding to channel-wise attention, element-wise attention, scale-wise attention
We can tell that element-wise attention is for deal with disease location & weight info, i.e: at each location on image, how likely there is a disease, as it been mention again when paper introduce the element-wise attention:
The element-wise attention learning aims to enhance the sensitivity of feature representations to thoracic abnormal regions, while suppressing the activations when there is no abnormality.
OK, we could easily get location & weight info for one disease, but we have multiple disease:
Since there are multiple thoracic diseases, we choose to estimate an element-wise attention map for each category in this work.
We could store the multiple disease location & weight info by using a tensor A
with shape (height, width, number of disease)
:
The all-category attention map is denoted by A ∈ RH×W×C, where each element aijc is expected to represent the relative importance at location (i, j) for identifying the c-th category of thoracic abnormalities.
And we have linear classifiers for produce a tensor S
with same shape as A
, this can be interpret as:
At each location on feature maps X(CA)
, how confident those linear classifiers think there is certain disease at that location
Now we element-wise multiply S
and A
to get M
, i.e we are:
prevent the attention maps from paying unnecessary attention to those location with non-existent labels
So after all those, we get tensor M
which tells us:
location & weight info about certain disease that linear classifiers are confident about it
Then if we do global average pooling
over M
, we get prediction of weight for each disease, add another softmax
(or sigmoid
) we could get prediction of probability for each disease
Now since we have label and prediction, so, naturally we could minimizing loss function to optimize the model.
ImplementationFollowing code is tested on colab and will show you how to implement channel-wise attention and element-wise attention, and build and training a simple model base on your code with DenseNet121 and without scale-wise attention:
QUESTION
I'm trying to write a batch file to update our paperwork folders for the new year, and I can't find a way to make this a one-click operation. I've got around a hundred folders all containing the following folders:
- 2020
- Archive
- 2018
- 2019
I need to move the 2020 folder (and all its contents) to the archive and create a new 2021 folder in its place. I'm using robocopy to do this in each individual folder, but I haven't been able to find a way to have the script go to the next folder when it's done. Making things more complicated, the top-level folders have no set naming structure.

I'm downloading two files from a C-More industrial HMI FTP server. I don't know what OS the HMI is running but I suspect that its FTP server has some quirks. Using Jython 2.7, one file can be read without difficulty but the other has a space in the file name and the normal wrap-in-quotes solution doesn't work - yet.
The following works in the Windows 10 FTP client.

Answered 2020-Dec-21 at 13:53The ftplib has no issue with spaces. The problem are the quotes you add to the RETR

Answered 2020-Dec-07 at 07:21Here's a jq solution that assumes the CSV input is very simple (e.g., no field has embedded commas), followed by a brief explanation.
To handle arbitrary CSV, you could use a CSV-to-TSV conversion tool in conjunction with the jq program given below with trivial modifications.
A SolutionThe following jq program assumes jq is invoked with the -R option.
(The -n option should not be used as the header row is read without using input
.)
