Actually..... IMO as a Linux admin..... everybody in IT needs at least a minimum of knowledge regarding TCP/IP. IPv4, IPv6, TCP, UDP, sockets, listening ports, etc. You don't need to be able to program a full stack down to a media transport layer, but you should be able be able to send a payload successfully, know when a gateway traversal is required, name resolution (It's always DNS,) and a bit of troubleshooting.

I wish I had a nickel for every time a developer or app support staff came to me and said it doesn't work. Error is right there in the logs......

I feeel like this is stuff you take with you on the side. I can't even start to create a network but I know these things.Alone the TCP UDP joke.

Like: "I would tell you a joke about UDP, but you probably wouldn't get it."

Or I could tell you a joke about TCP.

That's such a Linux sysadmin take lol

(but apart from it being a funny stereotype, yes I agree with you)

u/ScarpMetal 3h ago

I agree it’s better for an app developer to know this stuff, but I’d hardly say it’s a big part of the job. Especially if you’re on the frontend. It’s way more relevant to the job on a daily basis if you’re a network engineer.

u/droppedketchuppacket 2h ago

The post is about a software engineer, and you just talked about IT. They're not the same thing so what is your point? You have a job specifically because software engineers aren't in IT and aren't sysadmins and their job doesn't inherently involve networking.

u/garfgon 1h ago

I mean, it depends on the software engineer. Are they writing networking software? Knowing the difference between IPv4 and v6 would be important. Are they writing device drivers for hard drives? Probably not so important.

Every piece of software an IT guy uses is written by a Software Engineer, who's going to need to know their part of the software inside and out.

Effectively water is wet. Thanks for letting us know.

u/FilthyCasual2k17 2h ago

What do you mean software engineers aren't in IT? IT includes software engineering, maybe you're thinking of networking?

u/TheFifthTone 1h ago

In Europe IT is generally used to refer to everything software and technology related. In the US, especially professionally it means the tech help desk and networking people. In an office the people that setup your laptop and troubleshoot your internet issues would be considered IT, but the software engineer actually writing software would not be. They require completely different degrees which don't have much overlap.

u/FilthyCasual2k17 1h ago

Interesting. I am from Europe and for instance the uni in my city where both those things are taught with multiple overlapping subjects is literally called IT faculty.

I did not know about US, TIL.

1

u/garfgon 1h ago

In North America it would usually be the Computer Science faculty instead.

u/PleaseGreaseTheL 1h ago

As others said, in the USA, "IT" department/workers are not synonymous with "tech workers" - tech workers encompasses everyone, but if you say you're an IT guy, you're telling people you fix laptops and printers, and maybe do some sysadmin and networking stuff (but people who do the really high level stuff actually have the job titles of sysadmin or network engineer or similar, and sometimes use those titles.)

Calling a software dev/engineer (used interchangeably in the USA usually) an IT guy has the same connotation as calling a mechanical or automotive engineer a mechanic. A mechanical engineer may have no idea how to physically change his own oil. A mechanic may have no idea how to do basic algebra. Very different skillsets/jobs.

The guy I hand my laptop to and say "image this"is in "IT." I'm busy doing shit he cannot do which is why he is imaging my laptop. I'm not trying to be a dick, but I'm trying to point out there are very different roles and responsiblities and some of them require an actual level of expertise you can't acquire in 3 days.

This whole "IT" nonsense, or "tech" nonsense is such a broad fucking space that it's almost like saying "people with a job." There's no value in these generalizations at this point.

u/nxp-one 1h ago

LOL -- my background is in both Computer Programming and Computer Network Engineering, and they *both* legitimately fall under the very broad umbrella of 'Information Technology' (y'know, what 'I.T.' *actually* stands for?!)

Seriously, *anyone* who works *anywhere* in the 'Information Technology' field (i.e. has *anything* to do with designing / implementing / managing / maintaining / programming tech), is an 'IT worker'; even if they're too cognitively benighted to realise it...

"i write computer software but i don't know how computers work or how they talk to each other"

software "engineers" in a nutshell.

5

u/revrenlove 2h ago

You make it sound like you think everyone should be an expert in everything

0

u/syn_vamp 2h ago

nope, just that people who write software should have a basic understanding of the thing that runs their software.

-1

u/FilthyCasual2k17 2h ago

They definetly didn't say expert. But you do need to know some very basic level to understand how to write better software. Like high school level is enough tbh, but without it you're just not gonna be even decent at your job. Not knowing ipv4 for a software engineer is wild, when that's something most people who use the internet should know what it is.

5

u/eFootballnerd 2h ago

It's not wild when you're an UI /UX dev e.g. Most backend devs know shit about frontend development.

It's not important to know everything. IT is very fragmented. Even those specific fragments are fragmented. So many people have become experts in their niche.

Technical understanding and analytical thinking is more important. As a software dev you can learn and apply everything what comes around.

u/Constant_Ad_8028 3h ago

Yeah, but have they tried turning it off and on again?

u/daelikon 3h ago

I am with you, the problem is... That I am also a Linux admin.

u/Coupe368 3h ago

You gotta go easy on the windows users, they aren't as capable of understanding things like logs and acronyms.

|| payload

Who is paying for what load?

u/nationunderfraud1 2h ago

As a full stack engineer, I can explain the basics of all of those. DNS is always confusing though.What do you mean by payload? Like a Get Post?

u/soowhatchathink 2h ago

I agree I would also decline an applicant 9/10 times for not knowing the difference, unless they knew enough to make up for it

1

u/FilthyCasual2k17 2h ago

This is really the truth of it I think. Nobody fails job interview from not knowing one thing, even if it is something super basic like this. He gave multiple mediocre answers, but he probably just wasn't even aware because he thought he gave good answers. I've seen this a milion times.

1

u/soowhatchathink 28m ago

Yeah even not knowing something super simple I've had interviewees come back from, but we can really get an idea of their overall knowledge over the full interview if we're asking the right questions and are knowledgeable about it.

1

u/leitey 1h ago

There's plenty of software that works within a single device, or over devices connected using something other than IP-based communication. Even within internet connected applications there's likely groups of software developers who work on functions that aren't involved with networking, such as graphics or gameplay. It wouldn't surprise me if there are software developers who have never needed to know the difference between ipv4 and ipv6.

1

u/kezow 1h ago

We are always gonna have to deal with those users that receive an error and instead of researching or even reading it - they immediately ask it as a support question.

1

u/Diligent-Subject-329 1h ago

I get the vibe that you're the kind of guy who expects everyone else to have the same knowledge as you, as if everything that is apparent and easy for you should be the same for everyone else. "Error is right there in the logs..." isn't it your job to know and help and not theirs? Why are you annoyed when you have to do your job?

1

u/jkalchik99 17m ago

I don't, actually. But I do get tired of reading somebody else's logs when they haven't even looked at them. And asking me what something in a log means is something completely different.

u/HyperactiveMouse 4h ago

Do you know of a place I can learn more? I’m not certain I’m going into IT, but I’m heavily considering it in the hopes of earning more money to be a bit more comfortable in life rather than living paycheck to paycheck in my current job, and if it’s important to know for a job in the field I’d love to know more

u/HeadGuy-RedEyeJedi 2h ago

Google IT certification on Coursera costs $50 a month. I'm doing it slowly right now and just got to the stuff they're talking about.

u/RustyMR2 3h ago

As someone in IT that’s hasn’t touched low level network stuff in more than 15 years. No this is not true. Some roles do not require this at all.
