Long answer: the component that does "copy&paste" is not alone defined by the distribution. This is a function of the desktop system / window manager. In other words: there is no such thing as the "default system file" copier for "Linux".
There are file mangers like dolphin for KDE; or nautilus on gnome that all come with their own implementation of file copy. Some good, some not so much (try copying a whole directory with thousands of files with nautilus).
But the real question here: why do you want to do that? What makes you think that your file-copy implementation that requires an interpreter to run ... is suited to replace the defaults that come with Linux? Why do you think that your re-invention of an existing wheel will be better at doing anything?!
Edit: if your reason to "manage" system copy is some attempt to prevent the user from doing certain things ... you should better look into file permissions and such ideas. Within a Linux environment, you simply can't manage what the user is doing in the first place by manipulating some tools. Instead: understand the management capabilities that the OS offers to you, and use those! | 1 | 0 | 0 | 0 | I have coded a python app to manage file copies on linux, I want to know how can I get it to process copy/paste calls, like those launched by pressing ctrl + c/ ctrl + v or right click / Copy..., or drag and drop, instead of using system copier.
Can I do this for all deb based linux dist. or its on different ways for Ubuntu, Mint, Debian, and so on????

it picked up the 32-bit python correctly. My question is how to force conda to pickup 32-bit python 3.5.2? so I can use some of the packages that only support python 3.5.

installed both 32-bit and 64-bit pythons

The single quote in ''' should be escaped: '\''. Your backslash escapes the quote at Python level, and not the MySQL level. Thus the Python string should end with ENCLOSED BY '\\'';
You may also use the raw string literal notation:
r"""INTO TABLE table1 FIELDS TERMINATED BY ',' ENCLOSED BY '\'';""" | 2 | 1 | 0 | 0 | I built a simple statement to run a load data local infile on a MySQL table. I'm using Python to generate the string and also run the query. So I'm using the Python package pymysql.
This is the line to build the string. Assume metadata_filename is a proper string:
load_data_statement = """load data local infile """ + metadata_filename + """INTO TABLE table1 FIELDS TERMINATED BY ',' ENCLOSED BY '\'';"""
I originally had string substitution, and wanted to see if that was the issue, but it isn't. If I edit the statement above and commend out the ENCLOSED BY part, it is able to run, but not properly load data since I need the enclosed character
If I print(load_data_statement), I get what appears to be proper SQL code, but it doesn't seem to be read by the SQL connector. This is what's printed:
load data local infile 'filename.txt' INTO TABLE table1 FIELDS TERMINATED BY ',' ENCLOSED BY ''';
That all appears to be correct, but the Mysql engine is not taking it. What should I edit in Python to escape the single quote or just write it properly?
Edit:
I've been running the string substitution alternative, but still getting issues: load_data_statement = """load data local infile 'tgt_metadata_%s.txt' INTO TABLE table1 FIELDS TERMINATED BY ',' ENCLOSED BY '\'';""" % metadata_filename
Also tried raw strings:load_data_statement = r"""load data local infile 'tgt_metadata_%s.txt' INTO TABLE table1 FIELDS TERMINATED BY ',' ENCLOSED BY '\'';""" % metadata_filename
Also tried raw strings:load_data_statement = r"""load data local infile 'tgt_metadata_%s.txt' INTO TABLE table1 FIELDS TERMINATED BY ',' ENCLOSED BY '\'';""" % metadata_filename
And tried adding extra escapes: Also tried raw strings:load_data_statement = r"""load data local infile 'tgt_metadata_%s.txt' INTO TABLE table1 FIELDS TERMINATED BY ',' ENCLOSED BY '\\'';""" % metadata_filename

You should use %s instead of your strings and then (in this case text) would be your string. This is the most secure way of protecting from SQL Injection | 2 | 1 | 0 | 0 | I built a simple statement to run a load data local infile on a MySQL table. I'm using Python to generate the string and also run the query. So I'm using the Python package pymysql.
This is the line to build the string. Assume metadata_filename is a proper string:
load_data_statement = """load data local infile """ + metadata_filename + """INTO TABLE table1 FIELDS TERMINATED BY ',' ENCLOSED BY '\'';"""
I originally had string substitution, and wanted to see if that was the issue, but it isn't. If I edit the statement above and commend out the ENCLOSED BY part, it is able to run, but not properly load data since I need the enclosed character
If I print(load_data_statement), I get what appears to be proper SQL code, but it doesn't seem to be read by the SQL connector. This is what's printed:
load data local infile 'filename.txt' INTO TABLE table1 FIELDS TERMINATED BY ',' ENCLOSED BY ''';
That all appears to be correct, but the Mysql engine is not taking it. What should I edit in Python to escape the single quote or just write it properly?

So I have a list of 5 items. All items share the same features, let’s say each item has 3 features for the example.
I pass the list to a ranking function which takes into account the features of every item in the list and returns an arbitrary ordered list of these items.
For example, if I give the following list of items (a, b, c, d, e) to the ranking function, I get (e, a, b, d, c).
Here is the thing, I don’t know how the ranking function works. The only things I have is the list of 5 items (5 is for the example, it could be any number greater than 1), the features of every item and the result of the ranking function.
The goal is to train a model which outputs an ordered list of 5 items the same way the ranking function would have done it.
What ML model can I use to support this notion of ranking ? Also, I can’t determine if it is a classification or a regression problem. I’m not trying to determine a continuous value or classify the items, I want to determine how they rank compared to each other by the ranking function.
I have to my disposition an infinite number of items since I generate them myself. The ranking function could be anything but let’s say it is :
attribute a score = 1/3 * ( x1 + x2 + x3 ) to each item and sort by descending score
The goal for the model is to guess as close as possible what the ranking function is by outputting similar results for the same batch of 5 items.

Treat these as continuous values. So, you can think of your function as operating by taking five distinct input vectors x1, x2, x3, x4, x5 and outputting five scalar target variables t1, t2, t3, t4, t5 where the target variables for your training set are the scores the items get. For example, if the ranking for a single sample is (x1,4), (x2,5), (x3,3), (x4,1), (x5,2) then set t1=4, t2=5, t3=3, t4=1 and t5=2. MLPs have the "universal approximation" capability and given a black box function, they can approximate it arbitrarily close, dependent on the hidden unit count. So, build a 2 layer MLP with the inputs as the five feature vectors and the outputs as the five ranking scores. You are going to minimize a sum of squares error function, the classical regression error function. And don't use any regularization term, since you are going to try to mimic a deterministic black fox function, there is no random noise inherent in the outputs of that function, so you shouldn't be afraid of any overfitting issues. | 2 | 2 | 1 | 0 | I need some orientation for a problem I’m trying to solve.

Since the gateway address is the one present in the Object Dictionary of the CANopen, and the Gateway has addresses of modbus Slaves I/O, how to specify the address of the modbus input ?
As i can see it CANopen uses the node-ID to select the server and an address to select the property to read/write, but in this case i need to go farther than that and point an input.
just to be clear i'm in the "studying" phase i have no CANopen/Modbus gateway in mind.

In this way you have the possibility to duplicate the choosen file with another name. | 2 | 9 | 0 | 0 | Just got started with pycharm and was wondering how can I simply copy a file in pycharm for editing purposes? For instance, I have a file opened, want to edit the code but want to make sure that I do not accidentally "over-save" the original file.
In other environments, I can simply right click the file, and copy it to a new file. I do not see a 'copy to new file' option in pycharm, but instead I do have to manually open a new file (File>New>Python..), and then manually copy all the code from the original file and paste it in the empty new file.

I tried to use 230400 at first but the baud rate my microcontroller can produce is either 235294 or 222222. 235294 yields an error of -2.1% and 222222 yields an error of 3.55%. I naturally picked the one with the lower error however it didn't work and didn't bother trying 222222. For some reason 222222 works when 235294 though. So I don't actually have to use the 250000 baud rate I initially thought I'd have to.
I still don't know why pyserial doesn't work with those baud rates when putty does, so clearly my laptop can physically do it. Anyway will know in future to try more standard baud rates as well as when using microcontrollers which can't produce the exact baud rate required to try frequencies both above and below. | 1 | 3 | 0 | 0 | I'm trying to get pySerial to communicate with a microcontroller over an FTDI lead at a baud rate of 500,000. I know my microcontroller and FTDI lead can both handle it as can my laptop itself, as I can send to a putty terminal at that baud no problem. However I don't get anything when I try to send stuff to my python script with pySerial, although the same python code works with a lower baud rate.
The pySerial documentation says:
"The parameter baudrate can be one of the standard values: 50, 75, 110, 134, 150, 200, 300, 600, 1200, 1800, 2400, 4800, 9600, 19200, 38400, 57600, 115200. These are well supported on all platforms.
Standard values above 115200, such as: 230400, 460800, 500000, 576000, 921600, 1000000, 1152000, 1500000, 2000000, 2500000, 3000000, 3500000, 4000000 also work on many platforms and devices."
So, I'm assuming why it's not working is because my system doesn't support it, but how do I check what values my system supports/is there anything I can do to make it work? I unfortunately do need to transmit at least 250,000 and at a nice round number like 250,000 or 500000 (to do with clock error on the microcontroller).

One way could be to add a last_seen field to your User. Pick some arbitrary number(s) that could serve as a heuristic to determine whether someone is "active". Any sufficiently long gap in activity could trigger a reset of the active_login_count. This obviously has many apparent loopholes, the biggest I see at the moment being, users could simply coordinate logins and potentially rack up an unlimited number of active sessions without your application being any the wiser. It's a shame humans in general tend to use similar "logical" mechanisms to run their entire lives; but I digress...
You could make this approach more sophisticated by trying to track the user's active ip addresses. Add an active_ips field and populate a list of (n) ips, perhaps with some browser information etc to try and fingerprint users' devices and manage it that way.
Another way is to use an external service, such as a Redis instance or even a database. Create up to (n) session ids that are passed around in the http headers and which are checked every time the api is hit. No active session id, or if the next session id would constitute a breach of contract, no access to the app. Then you simply clear out those session ids at regular intervals to keep them fresh.
Hopefully that gives you some useful ideas. | 1 | 3 | 0 | 0 | I'm trying to write a basic Flask app that limits the number of active logins a user can have, a la Netflix. I'm using the following strategy for now:
Using Flask_Security
store a active_login_count field for my User class.
every time a successful login request is completed, the app increases the active_login_count by 1. If doing so makes the count greater than the limit, it calls logout_user() instead.
This is a bad solution, because if the user loses her session (closed the incognito mode without logging out), the app hasn't been able to decrement her login count, and so, future logins are blocked.
One solution is to store the sessions on the server, but I don't know how I would go about authenticating valid sessions. Flask_Sessions is something I'm looking into, but I have no idea how to limit the number of active sessions.
As per my understanding, in the default configuration, Flask generates new session cookies on every request to prevent CSRF attacks. How would I go about doing that? | How to limit number of active logins in Flask | 0 | 0 | 1 | 0 | 0 | 1,075 |

I initialize the class with self.name. However, the main purpose of this class it to retrieve data from an API passing self.name as a parameter, and then parsing the data accordingly. I have a class method called fetch_data(self.name) that makes the API request and returns ALL data. I want to store this data into a class instance variable, and then call other methods on that variable. For example, get_emotions(json), get_personality_traits(json), and get_handle(json), all take the same dictionary as a parameter, assign it to their own local variables, and then manipulate it accordingly.
I know I can make fetch_data(self.name) return data, and then call fetch_data(self.name) within the other methods, assign the return value to a local variable, and manipulate that. The problem is then I will need to call the API 5 times rather than 1, which I can't do for time and money reasons.
So, how do I make the result of fetch_data(self.name) global so that all methods within the class have access to the main data object? I know this is traditionally done in an instance variable, but in this scenario I can't initiliaze the data since I don't have it until after I call fetch_data().

On the backend, it's MongoDB to store the data scraped.
What I have done, is that, I can collect info on the given url, but all data are stored in the same db.collection.
I know I can get parameters using "-a" for running scrapy, but how should I use it?
Should I change the pipelines.py or the spider python file?

I building a web application (specifically in web2py but that shouldn't matter I don't believe) on Python 2.7 to be hosted on Windows.
I have a list of about 2000 items in a database table.
The user will be opening the application which will initially select all 2000 items into Python and return the list to the user's browser. After that the user will be filtering the list based on one-to-many values of one-to-many attributes of the items.
I'm wanting Python to hold the unadulterated list of 2000 items in-memory between the user's changes of filtering options.
Every time the user changes their filter options,
trip the change back to Python,
apply the filter to the in-memory list and
return the subset to the user's browser.
This is to avoid hitting the database with every change of filter options. And to avoid passing the list in session over and over.
Most of this I'm just fine with. What I'm seeking you advise on is how to get Python to hold the list in-memory. In c# you would just make it a static object.
How do you do a static (or whatever other scheme that applies) in Python?
Thanks for your remarks.
While proofreading this I see I'm still probably passing at least big portions of the list back and forth anyway so I will probably manage the whole list in the browser.

When my work is iterative, i.e. I run minimally changed version of some algorithm multiple times, the accumulated cost of repeated initialization can get large at end of a day.
I'm seeking an alternative approach (allowing to avoid the cost of repeated initialization without using a notebook) for the following reasons:
No "out of the box" version control when using notebook.
Occasional problems of "I forgot to rename variable in a single place". Everything keeps working OK until the notebook is restarted.
Usually I want to have usable python module at the end anyway.
Somehow when using a notebook I tend to get code that if far from "clean" (I guess this is more self discipline problem...).
Ideal workflow should allow to perform whole development inside IDE (e.g. pyCharm; BTW linux is the only option). Any ideas?
I'm thinking of implementing a simple (local) execution server that keeps the problematic objects pre-initialized as global variables and runs the code on demand (that uses those globals instead of performing initialization) by spawning a new process each time (this way those objects are protected from modification, at the same time thanks to those variables being global there is no pickle/unpickle penalty when spawning new process).
