Find fractions strictly not preceded by certain characters

Asked 2021-Jun-14 at 21:20

I'm trying to find fractions not preceded by a word followed by a /, for example, s2. My code doesn't work for that one but it's able to capture for other ones. Can you please help modify the regex expression? The expected is given followed by _f.

We could match either a regex lookaround to match the lower case letters ((?<=[a-z])) followed by either one or more space, comma ([, ]+) followed by any / and digits (\\d+) and other characters (.*) or (|) one or more digits and other characters and replace with blank ("")

...

ANSWER

Answered 2021-May-12 at 21:53

What happens here is that the code that sends back the response is executed before the axios responses arrive:

First, a call to a database (is that correct?) using a async/await approach.
Then you define a function that returns a Promise and call it processing the response in the then() function.
That piece of code is executed when the Promise is resolve()d (watch out there's no code to handle a rejected response).
Now the promise is resolved once the for loop ends, it doesn't wait for the axios promises to return, it just triggers the requests and continue. The code block after they return will be run in another moment.

If you want to solve this, one thing you could do is to use async/await everywhere, and make the calls sequentially, something like this:

QUESTION

Communicating with a Bronkhorst Mass Flow Sensor - Device has no serial number?

Asked 2021-Apr-30 at 15:24

I'm trying to communicate with a few scientific measurement devices in our lab and came across a strange issue. We use Bronkhorst Mass Flow Readers to measure the amount of helium gas running through our lines.

NOTE --- I'm running my code through git bash on a Windows 10 machine. The hardware is connected via an RS232 cable. I have not tested this on Linux, but I can if necessary for troubleshooting. We are forced to use Windows 10 because of a different piece of hardware. If Linux ultimately works, I'll need to find a Windows 10 solution anyway.

In an attempt to write a class to automate the COM port determination, I found that these devices don't output a serial number. The below code shows what I'm doing, I'll provide more detail momentarily.

...

ANSWER

Answered 2021-Apr-30 at 15:24

I can't imagine the devices do not have serial numbers.

Sorry, you did hit the jackpot with those Prolific chips. Apparently, they ship with no serial number written. Older devices did not even have a spot to write a unique serial number (see here).

If you are lucky your chips will be of the newer sort and you should be able to write a serial number yourself using Prolific's tool.

If that's not a solution for you (I'm thinking maybe those are client's products and you'd have to ask for their permission) maybe you can tweak pyserial to swallow and clean those numbers (whatever they are) you are getting.

If you look at the code that should not be very difficult...

I used to have some of these Prolific bridges but unfortunately, I could not find any of them so all of the above is just hearsay. Anyway, I hope you find it helpful.

EDIT: I got hold of one Prolific bridge but unfortunately, this one was of the older 2303HXA type. There is no OTP memory or even an EEPROM so writing the serial number is out of the question (there is no place to write it to).

But I can confirm the same behavior you got on Windows (I even got a warning informing me that the device has been phased out and not supported since 2012). On Linux, there is no serial number anywhere either.

I've also noticed that if you want to write to the newer chips you will need to supply the port with 6.5V instead of the normal 5V you get from the USB (Prolific offers an adaptor but I guess it should not be difficult to DIY it).

Logic to adopt when an webelement is showing and desapearring two times

Asked 2021-Apr-22 at 15:39

I'm struggling with something right now and I don't know how to solve this.

Using Selenium and Helium, I'm running some test on a web app.

At some point, the web app print a screen blocker. This screen locker appears and disappears two times.

I have to wait for the second one to disappear to move on to other stuff.

How can I do this?

ANSWER

Answered 2021-Apr-22 at 11:35

If you want it to just appear and disappear, you could just replace the first print with a blank string and then print a second message after putting a time.sleep(2). After the second message you can do the same.
