Go Tooling in Action

[@masticore252]

It's been 5 years since this video was uploaded and it's still awesome, very informative and concise Thank you for doing this! 💪

[@joeferrucci]

Probably one of the most useful Go videos on the web. +1

[@juhaszJanos]

It is really that one.

[@rishabhbohra]

This is the absolutely necessary information about Go that folks learning this language should get. Amazing! +1

[@gabrielpetry4099]

This is the best format for a video tutorial, i have ever seen.

mate, you are the Jeffrey Way of Golang. LOVE THE MUSIC! and specially the rhythm of you r tutorial. You are a natural, thank you so much. I tried so many videos, courses, books...was so lost. Finally making some progress in Go! Gracias!

[@damienstanton]

I find this is a good presentation for getting friends to try or move to Go. The documentation and tooling is just plain awesome, and this walks through it all. Thanks!

[@EdSchroedinger]

'in a nutshell' award! clear, reproducable, no frills, brilliant! ...and I like the catchy 8bit jingle introducing each step ^^ moreover, I actually was compelled to give vscode another go (no pun intended :D) as it seems to integrate very well with various sdk tools without being such a multi gigabyte giant like the full blown visual studio...

[@stillcuriouslychase]

+1 to that. I spend most of my time in vim and had a hard time getting delve working in VS Code, this video was the most compelling reason that caused me to switch.

[@dapodix]

Really liked this presentation style - quick, terse, to the point - kept me engaged and most of all, I learned :) Make more videos like this??

[@briiclv]

Thanks for sharing and explaining! I was using only "-bench" to detect if there is improvement after changing code. Now I'm inspired to dive into "pprof" :) Thanks!

[@bestformspielt]

Excellent presentation!

[@zhe_li]

Really like the part for profiling and benchmarking, looking forward to more stuff! ☺️

[@cazino4]

Great video particularly liked the fine-grained performance tuning techniques that was demonstrated. Had no idea GO shipped with such powerful integrated application runtime analysis tools. Thank you.

[@MVMn]

This video is simply great. Makes it so much easier to begin actually doing stuff with go. Thanks!

[@MrMgmuhilan]

This is absolutely great stuff for a beginner in go.. Thanks so much!

[@rajendragosavi2233]

You are a gem. I did use profiling earlier in go but this video gave much more info. Thanks a lot :)

[@kennethsizer6217]

Spectacular! From the pace and the content to the 8-bit retro sound effects. Spot on.

[@PanosGeorgiadis]

This is better than Netflix!

[@cenntraru]

Wow! Thank you SO MUCH for your amazing video. I'm coming from Python which is totally interactive so when my program crashes I can easily trace what went wrong, because Python executes code line by line and very often simple print statements are enough to find errors especially when I was just starting. Compiled langs are very different in that sense, one little error breaks whole compilation so it's much harder to find problems without using proper debuggers. This video is very helpful and now I can get everything I need to Go: IDE, debugger, profiler, the whole work-flow of a good Go programmer. Thanks again!

[@premrajm1329]

Really Great. I gave the mark 5/5. I believe, no-one can do better than this. Thank you very much

[@sahinnezerov9979]

Thank you for the most useful video. I also like the sounds in the video.

[@steffenn6372]

Hi Campoy Im on my journey to learn Golang and I really enjoyed the video :) It covered a lot of useful go tools I will be using and why didnt I start to learn this language before now damn. Another thing to mention is the Visual Studio code editor Im used to Jetbrains products like webstorm, phpstorm, etc. but just this debugging you showed us made me switch from webstorm to VS Code. I cant wait to see more videos from you 👍

[@marcsantiago2238]

Awesome! Thanks for taking the time to make such a video. It has now been added to my list of reference tools!

[@Nightwulf1269]

If I could have been able to give more than one "thumbsup", I would give 10 of those. Well done!

[@thetooth]

Nice! Very clear voice and easy to understand(what is it with youtube screencasts and people doing voice overs in drain pipes). Been using Go for a while and good to be reminded that these tools exist, sometimes forget since also using VSCode so it's all automated.

[@Luix]

I cannot believe I enjoined a programming video so much

[@higiniofuentes2551]

Thank you for this awesome and very useful video!

[@morwar_]

very nice video, this was really great. I didn't know that VSCode was so neat, with all the debugging and stuff. Thanks for the video!

[@morwar_]

after I saw the video I was thinking "Man, I know that 'Francesc' name from somewhere". I just realize that you will talk in the GopherConBR 2016 in Florianópolis SC, Brazil. I'm already excited about your talk. See you there!

[@JustForFunc]

Hah, it's a small world!

[@AmarjeetAnandsingh]

Thank you so much for this video. Very helpful.

[@mohammedhewedy8231]

Perfect thanks, especially the profiling part.

[@clemensqueiner849]

Superb ! Thanks. That was really eyes opening for me.

[@mujibrahmanbd]

A brilliant presentation by fransesc. Thanks :)

[@ulissemini5492]

best golang video ever!

[@mybigbeak]

Really appreciate all the tips in this. Thanks

[@paracha3]

What an amazing video. Learnt so much new.

[@dc5]

Awesome... as usual. Thank you Francesc!

[@dgolja]

Really good presentation ! Thank you

[@weblancaster]

So good. Thank you.

[@audreyli836]

Great video! Lots of useful tips!

[@RichardBuckerCodes]

this editor is so simple it should be runnable in a browser.

[@tudor_turcu]

Nice presentation! One small issues: at least on Windows, the format for go list does not 'like' spaces, only go list -f '{{.Name}}:{{.Doc}}' works..

[@sluongng]

I think there were a small part missing which is to introduce how to setup VS Code for GoLang (installing which package etc..)

[@NekonyaNyaNya1]

very cool stuff my man

[@danvilela]

Excellent!

[@shawnmofid7131]

Thank you for creating these presentations. I love the language. If I do not end up working for Google, can I still use Go? I mean would you do a video on use case scenarios Go would do better than other languages? I did hear somethings about this in your other videos, but I have not found any content yet that would say something like these are they type of activities and environment, which Go would shine in. I also wonder why I never ran into the idea of channels in .net and C# development. This is partly because I am very new to programming, and I have focused on C# and .net mainly. Are they the same as IOstreams?

[@AmarnathReddyDornala]

Omg you are amazing dude. :bow:

[@stephenkamenar]

That was a really well done tutorial

[@hahsun6470]

Very nice. Thank you!

[@mehranrafiee4063]

This was awesome Thanks dude!

[@ShepardEffekt]

This was great! Thank you

[@FilipMarekk]

Really good video, thank you for it!

[@oneryx]

Nice video, very helpful.

[@lolpanda0]

Great video! I noticed your http handler took 52ms under stress at the slowest request. Do you know how this possibly simplest handler could go such slow?

[@JustForFunc]

my laptop was recording at the same time and ScreenFlow loves eating CPU so I wouldn't trust much on the absolute values :)

[@ChalithaWikramathilaka]

thanks for the tutorial, easy to understand... :)

[@DavidGuan]

Thanks, leant a lot.

[@CaseyCS7]

Great video! Thanks a lot!

[@michaeldasilva6753]

quality video, good job

[@MrOgrable]

For go-wrk : look in the description for the correct repo. The repo printed in the video (github.com/adjust/go-wrk) is not the repo used on screen (github.com/tsliwowicz/go-wrk)

[@igalshnaider7919]

Thank u very mach, awesoem !!!!

[@berma3726]

No, thank you for that great video!

[@meditating010]

Awesome!

[@jeffreyguan8387]

so cool

[@hunar-ahmad]

that was awesome. thanks

[@chandragarre2036]

vscode is awesome.

[@arangogutierrez]

Which is your recommended build tool for big Go projects. Make or bash?

[@egretx2652]

like the music....

[@Daidera91]

Hi, i got a question. Compared to the structure and support you get with things like routing in a web framework like django in python... would you still take google go for larger web projects? I ask cause we are working on our start up and thinking about moving to go :)

[@Nerd2k7]

awesome!

[@Jonas-jj1zc]

At 40:34 there's still net/http.DetectContentType in the Graph, that shouldn't be there anymore, or should it? Did I miss something?

[@xnoreq]

He forgot to update the graph after that last tweak. But if you're that much into performance you shouldn't use Go anyway.

[@Jonas-jj1zc]

John Doh just wanted to be sure I understand it correctly, thank you!

[@farhanyousaf5616]

@@xnoreq Use Rust or C... Though, Go, is by far, the easiest language to grasp and create super fast websites. I don't think Rust is there yet.

[@sgtWolfgang]

Great presentation! On another note, when trying to do go-wrk -d url, It keeps executing for 1 second and giving me the benchmark output. I looked at the code and a -d flag is not supported it seems. Is anyone else seeing this behavior? Thanks in advance.

[@nerdbenana]

The right one is github.com/tsliwowicz/go-wrk

[@NitishKumar-nz8qy]

Awesome

[@komuwairagu3942]

awesome

[@magicly007]

good lecture, thanks so much~

[@agendaaaa]

thanks

[@simonholdsworth6867]

What shell / terminal program do you use or recommend for Mac?

[@AliBigdeli]

it was useful

[@布雷-z7h]

time at10:01, what is the 'errcheck' command

[@WeiseGuy91]

I get an error saying errcheck command not found. How do I fix that?

[@dmitriysuhinin]

Could you explain how to configure Debugging under MacOS?

[@JustForFunc]

follow this guide carefully :-) github.com/derekparker/delve/blob/master/Documentation/installation/osx/install.md

[@GertCuykens]

How did you paste your selected output to cat > file on mac?

[@SarkisVarozian]

Do you all still use $GOPATH when developing these days or made the switch to modules and developing outside $GOPATH?

[@ketub]

what is the font in the terminal?

[@skaldence3073]

Very nice video, it helped me a lot :) Just a little thing, you did not link the source of go-wrk you are actually using. You linked from github.com/adjust (which is not working very good), but you used github.com/tsliwowicz, which is a far better tool :D

[@JustForFunc]

good catch! I'll change the annotation

[@tcsiwula]

I love you 😍

[@fenghu5850]

Asesome

[@hishamkaram2119]

vscode debug in windows not working

[@JustForFunc]

have you gone through the installation process here? github.com/derekparker/delve/tree/master/Documentation/installation

[@hishamkaram2119]

+JustForFunc first thank you so much second after 7 hours searching web and nothing help me i found that bitdefender block dlv.exe and debug process then uninstall bitdefender. every think working 😎

[@theblacktechexperience]

i thought fmt was format. fomt

[@easternsunking255]

errcheck tool ,where can i install it? is this link go get -u github.com/kisielk/errcheck ?

[@mikoajkakol7813]

4000ns/op is 4us/op :-) not milliseconds as you told, it's amusing how often people confuse those

[@c2oo7]

Would you like to tell me what editor/ide to be used?

[@SARANSASIDHARAN1]

Thank you.. That was awesome...

[@AdityaFingerstyle]

Excellent !

[@ancogamer]

Amazing video ! Thanks !
