QUESTION
I want to port the working matlab code of a GA to python. In matlab I get to optimum within a 10% margin (good enough for a quick glance) with a population of 10 and 10K generations. Now I tried to port this code to python and get the odd behaviour that the solution seems stuck on a specific (but random) value sometimes way too far from the optimum.
A call of example1p6A(10000,10,0,0) using the provided matlab code results in

QUESTION
I have a device, a Geiger counter, which is programmed to issue a HTTP request on my local network to an Apache server on that same network. This server always answers with "400 Bad request". Consistent with that, Apache's error log says: "AH00566: request failed: malformed request line".
Now I copy this "malformed" line taken from wireshark output, and enter this line into a browser (both Firefox and Chrome used): The server gives a 200 response, and of course no error. So seemingly the HTTP request is proper. Why is it not when coming from the Geiger counter?
Should wireshark not give an answer? I have reached my limit in interpreting wireshark, and I hope you can help.
I am attaching the 2 lines from wireshark, the request and the response, fully expanded, hoping that this contains the things I need to look out for.
EDIT: I have now added the mod_log_forensic module to my Apache server. This is supposed to give me all header info before and after processing them. The bummer is, it gives me all header info when the request succeeds, but none whatsoever when it fails as in my cases with "malformed requests". I don't see any options to set for this module :-((
...ANSWER
Answered 2021-Sep-16 at 07:45The question has found an answer over at Wireshark: https://ask.wireshark.org/question/24316/where-do-i-even-look-to-find-the-reason-for-a-400-bad-request/?answer=24330#post-id-24330
The problem is that the Geiger counter formed a http request which is not fully in accordance with the http rules: https://datatracker.ietf.org/doc/html/rfc7230#section-3.5
I.e, it concluded the http request with a LF-only, while it should have send a CRLF.
A Microsoft ASP server accepts this, while an Apache server rejects it as a security issue (https://httpd.apache.org/security/vulnerabilities_24.html, scroll to: "important: Apache HTTP Request Parsing Whitespace Defects (CVE-2016-8743)")
One can overcome the Apache rejection by inserting HttpProtocolOptions Unsafe into apache2.conf. Tested on my local Apache server and it works!
I wonder how the admins will feel of inserting the word "Unsafe" into their config files ...
QUESTION
I am trying to transfers a packet from an interface to another by using raw packets (just for playing). First I focused on received packets.
On my machine (archlinux, that has 192.168.30.3 as IP) I created this code:
...ANSWER
Answered 2021-Aug-23 at 08:52Since the observed total packet length is way greater than that of a typical jumbo frame (MTU 9k), it's apparent that the receiver side employs either Large Receive Offload (LRO) or Generic Receive Offload (GRO) thus reassembling smaller packets into larger ones on the network interface driver level. This might explain why the packet socket in question sees already reassembled (large) packets.
In this specific case, ethtool -k output indicates clearly that LRO is always disabled whilst GRO is indeed active and can be adjusted. As per the discussion in comments, disabling GRO indeed bears fruit.
QUESTION
I am working on a project to upload my trades directly to an app I am building, by consuming a CSV file produced by my broker, instead of having to manually enter trades in a journal or paying for one.
My problem is that the data is represented as transactions not trades, therefore I have to match transactions (Buys/sells) and create another object from that. The reason I want to create a "Trade" Object is to store a list of them in a database and pass those objects to other methods to calculate stuff.
Here is what the data looks like from my broker:
Here is the Header for the CSV file:
Account,T/D,S/D,Currency,Type,Side,Symbol,Qty,Price,Exec Time,Comm,SEC,TAF,NSCC,Nasdaq,ECN Remove,ECN Add,Gross Proceeds,Net Proceeds,Clr Broker,Liq,Note
Sample data of the CSV file containing multiple examples of transactions:

Here, I matched the same transactions per color to better explain the concept. In yellow are two transactions forming 1 trade. The opening transaction is a "Buy" (B), therefore to close it, the matching transaction should be a "Sell" (S).
Same concept, slightly more complicated in green. The opening trade is a "Buy" with 450 as quantity. The subsequent transactions are also "Buy" with the same symbol, therefore adding to the position (450 + 75 + 15 = 540 quantity). A matching transaction to close the trade should be "Sell", but it could also be in increments. So I should keep track of quantity once a trade is initialized. See how the last green transaction is a sell of 540 quantity with the same symbol, bringing the total quantity to zero for the trade, meaning the trade is completed (Closed).
I have made a Transaction class with all the required fields, a constructor, getters and setters, as well as a Trade class.
...ANSWER
Answered 2021-Mar-19 at 17:34For your first problem,
- Sometimes I scale out of positions meaning that I do not sell in 1 transactions (Multiple transactions to close trades), which means I would have to match multiple transactions.
Use groupingBy method :
Group your transactions by 'symbol' and collect as map.
Map postsPerType = transactions.stream() .collect(groupingBy(Transactions::getSymbol));
This way you get all transactions grouped together.
- There is the possibility of a trade being still partially opened in the list passed. I do not know how to handle that possibility.
Iterate above collected transactions and match the quantity by filtering out Buy and Sell transactions to ensure whether trade is completed.

I have a text file from which I need to extract certain data. The data I need will appear under a header that begins with "No.". So I know what to look for when searching the file and I can split and print each header. However, I want to extract the data that is on the next line of the one that begins with "No." I cannot use regex either. How can I accomplish this? I was able to successfully locate each header in the file using the below code but as mentioned I want to get the next line.

I want to use a DB that will keep track of our ECNs here at work. So I have a table for the ECN entries. ECN Entries Table When the use clicks on the hyperlink to open the document, I create a record in a log table like this: Log Entries Table. What I want to do is show a form that will only display ECN entries that have not been viewed yet. This is the query that I am trying to come up that will show the ECN entries that have not been viewed.
SELECT ECNEntries.* FROM ECNEntries, Logs WHERE ******
So I have this query that will set a recorset based on 3 conditions: 1- User Name 2- Log Type 3- ECN Number
...ANSWER
Answered 2020-Nov-25 at 20:32Seems like at its heart, you need to join Entries and Logs to find all the times Logs does not have a corresponding match for this entry + user. That is the definition of a LEFT JOIN.
