Place for feedback?

Where do we report typos or issues with LFS201 please? Nothing major to report, but it would be nice to offer feedback if possible.

This post suggests we send them to training@linuxfoundation.org:

Thanks,

Thanks for the link Adam. I'd also asked Foundation via their social media pages, without any response. Lots of course promo but no clear channels for user interaction. Can't be the Linux way!

Hi sorry, I didn't realize I was supposed to be monitoring this. Indeed the best way to send us typos, corrections, etc is to mail training@linuxfoundation.org. Please mention LFS201 in the subject.

We have been continually revising the class, fixing minor errors, typos and adapting students' suggestions and we welcome them.

Hi,

Sorry too -- didn't mean to come across as critical. It really is a great course so far!

I have generated heaps of course notes so far and remembered to jot down a few glitches along the way. I will email them as suggested.

Thanks,

David Harrison

I tried to send an email to training@linuxfoundation.org with some feedback about the LFW211 course, but I get an automatic response with this message: "This email address is no longer accepting Training & Certification Customer Support Requests.". Is there another way to send feedback?. Thanks.

Hi @federicopenaranda

That email has been disabled for a couple of years. Content related feedback can be provided in this forum.

Thank you,

Hi, I'm doing the LFW211 course, and I found a couple of things that could be an error:

1) In the page of the link below, the text mentions a flatstr package, but I couldn't find that package in the list of packages that the page shows.
https://trainingportal.linuxfoundation.org/learn/course/nodejs-application-development-lfw211/packages-dependencies/packages-dependencies?page=4

2) In the lab 2 on "Key Javascript Concepts" are some lines of code that validates the script with some assert statements:
https://trainingportal.linuxfoundation.org/learn/course/nodejs-application-development-lfw211/key-javascript-concepts/lab-exercises?page=2

assert(Object.getOwnPropertyNames(felixProto).length, 1)
assert(Object.getOwnPropertyNames(felixProtoProto).length, 1)
assert(Object.getOwnPropertyNames(felixProtoProto).length, 1)
assert(typeof felixProto.meow, 'function')
assert(typeof felixProtoProto.purr, 'function')
assert(typeof felixProtoProtoProto.hiss, 'function')
console.log('prototype checks passed!')

I believe that it should be like this (I put the change in bold text on the line with an arrow):

assert(Object.getOwnPropertyNames(felixProto).length, 1)
assert(Object.getOwnPropertyNames(felixProtoProto).length, 1)
---> assert(Object.getOwnPropertyNames(felixProtoProtoProto).length, 1)
assert(typeof felixProto.meow, 'function')
assert(typeof felixProtoProto.purr, 'function')
assert(typeof felixProtoProtoProto.hiss, 'function')
console.log('prototype checks passed!')

Just to let you know in case it can improve the course.

Regards.

Hi, I'm doing the LFW211 course, and I found a typo, double "the":

Using a caret on version numbers is basically the same as using an x in the MINOR and PATCH positions, so ^7.6.2 is the same as 7.x.x. However there are exceptions when using 0, for example ^0.0.0 is not the the same as 0.x.x, see the "Caret Ranges ^1.2.3 ^0.2.5 ^0.0.4" section of npmjs Documentation. For non-zero MAJOR numbers, ^MAJOR.MINOR.PATCH is interpreted as MAJOR.x.x.

Hi, I'm doing the LFW211 course, and I found a typo in the code:

https://trainingportal.linuxfoundation.org/learn/course/nodejs-application-development-lfw211/nodes-module-systems/nodes-module-systems?page=6

const isMain = process.argv[1] &&
await realpath(fileURLToPath(import.meta.url)) ===
await realpath(process.argv[1])

It should be:

const isMain = process.argv[1] &&
---> await realpath(url.fileURLToPath(import.meta.url)) ===
await realpath(process.argv[1])

Regards.

Hi @federicopenaranda ,

You can post in the LFW211 forum (because this one is for LFS201):

Regards,

Oops!, sorry!.

re the example command here https://trainingportal.linuxfoundation.org/learn/course/essentials-of-linux-system-administration-lfs201/rpm/rpm?page=3

do NOT parse the output of ls, use the find command instead, more details here https://mywiki.wooledge.org/ParsingLs

it works in this case, but this is an anti-pattern, it should not be taught like this
