QUESTION
I am using NesTing library within omnet++. For scheduling of switch gates a gate control list is defined within a xml file which is loaded by the .ini file. For example,
...ANSWER
Answered 2022-Mar-22 at 10:42I believe NesTing is not prepared to change the parameters and scheduling on the fly. So you cannot do that.

Following this tutorial, I am trying to extract basic property information from zillow.com. More specifically, I want to extract the information pertinent to property cards displayed on the website.
The following code is able to extract information of only 3 properties, even though several property cards exist on the first page. Can someone please explain why is the code skipping the remaining properties?

ANSWER
Answered 2022-Jan-31 at 20:27I can't reproduce the behavior you're seeing. I compiled Maxima 5.43.2 (version number slightly mixed up in build_info output below) and I don't get the results you're seeing. Here's what I see with the command line interface (I get the same result with wxMaxima).
QUESTION
We have an application that tries to migrate existing application logs of about a year into google cloud logging. I have created a custom logging bucket with a retention time of 400d and a custom sink that writes all the requests for a given logName into this bucket. I also excluded this logName from the _DEFAULT bucket.
Now if i write log entries for the given logName, with timestamps from all over the last year, all entires that are older than 30d are discarded. I even increased the retention time of the _DEFAULT bucket to e.g. 60d but still no logs older than 30d can be written. That means that the write successfully happened for all log entries but only entries that are older than 30d do not show up in the Log Explorer.
According to Routing - Log Retention the bucket should define the retention period:
Cloud Logging retains logs according to retention rules applying to the log bucket type where the logs are held.
Also there doesn't seem to be any quota that should limit this.
Does anybody know why entries with a timestamp older than 30d are silently discarded despite properly configured logging bucket and sink?
Or are there any better solutions to import logs into GCL without having to write a custom app to do so?
...ANSWER
Answered 2022-Jan-26 at 23:34Cloud Logging currently has time bounds on the timestamp of the LogEntries it can ingest in its storage. Logs can only be ingested if the timestamps are within the last 30 days or 1 day in the future. This applies even if your bucket retention period is set to 60 days or more.
This is a current limitation and may change in the future.

QUESTION
handler-case is key to handling conditions in Common Lisp, but GCL 2.6.12 on Ubuntu 18.04 considers it to be an undefined function:
ANSWER
Answered 2021-Jul-01 at 08:01The situation is explained in the project's README.Debian:
[...] The common lisp standard in effect when GCL was first released is known as "Common Lisp, the Language" (CLtL1) after a book by Steele of the same name providing this specification. Subsequently, a much expanded standard was adopted by the American National Standards Institute (ANSI), which is still considered the definitive common lisp language specification to this day.
[...]
To toggle the use of the ANSI image, set the environment variable GCL_ANSI to any non-empty string.
(This Debian bug has a little more info.)
handler-case requires ANSI support, so on Debian-based systems, GCL needs to be started with the GCL_ANSI environment variable set; for example:
QUESTION
So I am working on a Maxima program that involves a bunch of iterations (the Souriau-Frame Drazin Inverse Algorithm, to be specific), each step of which yields a polynomial. I need to check and stop my iterations when the polynomial goes to zero (i.e., all coefficients go to zero).
Maxima seems to never truncate small numbers to zero up until it reaches something absurd like $10^{-323}$ and so on.
The following code snippet gives an idea of what I need:
...ANSWER
Answered 2021-Apr-16 at 03:58First let's step back a moment. What is the behavior you are hoping to find? If you need to convert very small floats to rational numbers accurately, try rationalize instead of rat. Does that work correctly for 1e-323?
If you want floats smaller than a tolerance to be converted to zero, we'll need to take a different approach. I'll hold off on that for the moment.
About the specific behavior you have observed, it appears to be implementation-dependent; I get a different (still buggy) behavior with Maxima + SBCL, which reports a floating point overflow. What does build_info(); report?
I don't know if it matters, but 1e-323 is a so-called denormalized float -- it is smaller than the smallest normalized (full precision) float, which is about 1e-308.

I'm trying to use and convert following code in a Pine screener
...ANSWER
Answered 2021-Feb-04 at 09:07All calculations that are necessary for the function screenerFunc must be included in this function. Also, if you use the history access operator [1], you must first declare the variable. The errors in the script below are fixed, but you should check for yourself whether the script creates the labels correctly.
