Hello devRant, a question for you.

I'm looking to redisign/setup my server 'infrastructure'.

It'll exist out of:
7 vps's (6+gb ram/500gb+/100mbs up/down per vps)
2 dedicated servers running as virtualization servers. (16gb/4tb/1gbit up/down and another one but let's leave that one out for now because it's gonna take a shit ton of time to solve that clusterfuck)

One server will function as an entry point for all websites I run, multiple database servers and multiple backup ones.

Any advices/tips/ideas?

Just a very serious hobby thing :)

friend of mine: "I like my servers like I like my girls"
me: "insecure?"

So, I was gonna rant about how it can be difficult to design event-based Microservices.

I was gonna say some shit about gateways APIs and some other stuff about data aggregation and keeping things idempotent.

I was going to do all this but then as I was stretching out the old ranting fingers I decided to draw a diagram to maybe go along with the rant.

Now I’m not here to really rant about all that Jazz...

I’m here to give you all a first class opportunity to tear apart my architecture!

A few things to note:

Using a gateway API (Kong) to separate the mobile from the desktop.

This traffic is directed through to an in intermediate API. This way the same microservices can provide different data, and even functionality for each device.

Most Microservices currently built in golang.

All services are event based, and all data is built on-the-fly by events generated and handled by each Microservices.

RabbitMQ used as a message broker.

And finally, it is hosted in Google Cloud Platform.

The currently hosted form is built with Microservices but this will be the update version of things.

So, feel free to rip it apart or add anything you think should change.

Also, feel free to tell me to fuck right off if that’s your cup of tea as well.

Peace ✌🏼

Any upcoming "online hackathon" ?!

My first complete pipeline with Jenkins:

- push on gitlab
- build with maven
- test with junit
- deploy with Ansible
- integration test with Selenium

I love devops!

rant? rant!

I work for a company that develops a variety of software solutions for companies of varying sizes. The company has three people in charge, and small teams that each worked on a certain project. 9 months ago I joined the company as a junior developer, and coincidentally, we also started working on our biggest project so far - an online platform for buying groceries from a variety of vendors/merchants and having them be delivered to your doorstep on the same day (hadn't been done to this scale in Estonia yet). One of the people from management joined the team working on that. The company that ordered this is coincidentally being run by one of the richest men in Estonia. The platform included both the actual website for customers to use, a logistics system for routing between the merchants, the warehouse, and the customers, as well as a bunch of mobile apps for the couriers, warehouse personnel, etc. It was built on Node.js with Hapi (for the backend stuff), Angular 2 (for all the UIs, including the apps which are run through a WebView wrapper), and PostgreSQL (for the database). The deadline for the MVP we (read: the management) gave them, but we finished it in about 7 months in a team of five.

The hours were insane, from 10 AM to 10 PM if lucky. When we weren't lucky (which was half of the time, if not more), we had to work until anywhere from 12 PM to 3 AM, sometimes even the whole night. The weekends weren't any better, for the majority of the time we had to put in even more extra hours on the weekends. Luckily, we were paid extra for them, but the salary was no way near fair (the majority of the team earned about 1000€/mo after taxes in a country where junior developers usually earn 1500€/month). Also because of the short deadline given to us, we skipped all the important parts like writing tests, doing CI, code reviews, feature branching/PR's, etc. I tried pushing the team and the management to at least write tests and make feature branches/PRs, but the management always told me that there wasn't enough time to coordinate and work on all that, that we'll do that after launching the MVP, etc. We basically just wrote features, tested them by hand, and pushed into the "test" branch which would later get tested and merged into master.

During development, one of the other juniors managed to write the worst kind of Angular code you could imagine - enormous amounts of duplication, no reusable components (every view contained the everything used in the view, so popups and other parts that should logically be reusable were in every view separately), fuck - even the HTML was broken (the most memorable for me were the "table > tr > div > td" ones, but that's barely scratching the surface). He left a few months into the project, and we had to build upon his shit, ever so slightly trying to fix the shit he produced. This could have definitely been avoided if we did code reviews.

A month after launching the MVP for internal testing, the guy working on the logistics system had burned out and left the company (he's earning more than twice the salary he got here, happy for him, he is a great coder and an even better team player). This could have been avoided if this project had been planned better, but I can't really blame them, since it was the first project they had at this scale (even though they had given longer deadlines for projects way smaller than this).

After we finished and launched the MVP, the second guy from management joined, because he saw we needed extra help. Again I tried to push us into investing the time to write tests for the system (because at this point we had created an unstable cluster fuck of a codebase), but again to no avail. The same "no time, just test it manually for now, we'll do that later when we have time" bullshit from management.

Now, a few weeks ago, the third guy from management joined. He saw what a disaster our whole project was. Him joining was simply a blessing from the skies. He started off by writing migrations using sequelize. I talked to him about writing tests and everything, and he actually listened. He told me that I'm gonna be the one writing them, and also talked to the rest of management about it. I was overjoyed. I could actually hear the bitterness in the voices of the rest of management when they told me how to write the tests, what to test, etc. But I didn't give a flying rat's ass, I was hapi.

I was told to start off by writing a smoke test for the whole client flow using Puppeteer. I got even happier, since I was finally able to again learn new things (this stopped at about 4 or 5 months into the project).

I'm using jest as the framework and started writing the tests in TypeScript. Later I found a library called jest-extended, but it didn't have type defs, so I decided to write them and, for the first time in my life, contribute to the open source community.

Don't do "git pull" quickly. Always do a "git fetch" THEN "git log HEAD..origin" OR "git log -p HEAD..origin". It is like previewing first what you will "git pull".

OR something like (example):
- git fetch
- git diff origin/master
- git pull --rebase origin master

Sometimes it is a trap, you will pull other unknown or unwanted files that will cause some errors after quickly doing a git pull when working in a team. Better safe than sorry.

Other tips and tricks related are welcome 😀

Let the student use their own laptops. Even buy them one instead of having computers on site that no one uses for coding but only for some multiple choice tests and to browse Facebook.

Teach them 10 finger typing. (Don't be too strict and allow for personal preferences.)

Teach them text navigation and editing shortcuts. They should be able to scroll per page, jump to the beginning or end of the line or jump word by word. (I am not talking vi bindings or emacs magic.) And no, key repeat is an antifeature.

Teach them VCS before their first group assignment. Let's be honest, VCS means git nowadays. Yet teach them git != GitHub.

Teach git through the command line. They are allowed to use a gui once they aren't afraid to resolve a merge conflict or to rebase their feature branch against master. Just committing and pushing is not enough.

Teach them test-driven development ASAP. You can even give them assignments with a codebase of failing tests and their job is to make them pass in the beginning. Later require them to write tests themselves.

Don't teach the language, teach concepts. (No, if else and for loops aren't concepts you god-damn amateur! That's just syntax!)

When teaching object oriented programming, I'd smack you if do inane examples with vehicles, cars, bikes and a Mercedes Benz. Or animal, cat and dog for that matter. (I came from a self-taught imperative background. Those examples obfuscate more than they help.) Also, inheritance is overrated in oop teachings.

Functional programming concepts should be taught earlier as its concepts of avoiding side effects and pure functions can benefit even oop code bases. (Also great way to introduce testing, as pure functions take certain inputs and produce one output.)

Focus on one language in the beginning, it need not be Java, but don't confuse students with Java, Python and Ruby in their first year. (Bonus point if the language supports both oop and functional programming.)

And for the love of gawd: let them have a strictly typed language. Why would you teach with JavaScript!?

Use industry standards. Notepad, atom and eclipse might be open source and free; yet JetBrains community editions still best them.

For grades, don't your dare demand for them to write code on paper. (Pseudocode is fine.)

Don't let your students play compiler in their heads. It's not their job to know exactly what exception will be thrown by your contrived example. That's the compilers job to complain about. Rather teach them how to find solutions to these errors.

Teach them advanced google searches.

Teach them how to write a issue for a library on GitHub and similar sites.

Teach them how to ask a good stackoverflow question :>

I am thinking to start freelancing with PHP. I need more money besides my actual job and I just love to code.

It will be my first time developing profissionaly.

Any tips?

*Changes everything he possibly can for 2 hours*
None of the changes are reflected 🚫

Realizes he is making changes on live database and viewing development 🤔
*Switches to development*

Forgets to switch back to live 👴
*Pushes project with development connection to live*

Doing Linux server management stuff via ssh with a FUCK 500ms PING IS NOT FUN AT ALL

GET OFF THE FUCKING NETWORK EVERYONE 😤😤😤😤😤

The PCs in our school have a software called "Dr. Kaiser" which purpose is to prevent changes to the disk. I thought it's working like DeepFreeze for OSX devices; having a copy-on-write feature or something like that. One day a friend of mine (kinda newbie in hacking) said he wanted to create a backdoor in the system so you can login as the local administrator of the device. He replaced the "sethc.exe" in the windows directory with cmd.exe on a live distro and claimed it was working perfectly. It turned out that "Dr. Kaiser" is indeed loading the default image on startup, but doesn't verify checksums for system files (and also doesn't include the files in the default image). Long story short: You now can open a cmd with System permissions on every PC in the building.

This. Is. Stupid. It should be forbidden to sell this software 😖

Just finished this great book! It was really entertaining and interesting 🙂
And it explained the advantages of DevOps and CI/CD in a very understandable way 😁

Do you have any other good recommendations for IT novels?

I'm a junior dev less than 1 year into my first job out of college. I'm halfway done reading Clean Code (my first software book out of college) and I'm really enjoying it!

What should I read next? I was thinking something about design patterns. Should I go for the classic GoF book or continue with Robert C Martin and read "Agile Software Development, Principles, Patterns, and Practices"?

For fucks sack I just created my server and fail2ban already blocked 6 IP addresses dafuq is going on on the internet 😓

I'm the worst with color combinations and I want to enable dark mode on the privacy/security blog!

What color combinations (if you have hex codes or something, please share!) would you think would suit the blog?

Halp :P

When management produces a list of priorities but every item on the list is #1 priority. So some items are in BOLD to signify their even greater priority over other priorities.

As much as I love developing I have been also enjoying pentesting a lot lately.

So if you have any resources for a beginner to share please link them in the comments :)

The past 2 years where I work:

Me: hey let's use git instead of ftp!
Boss: should we?
Some time later: he is loving it...

Me: hey let's use trello instead of excell!!??!
Boss: huumm.. Dunno... Should we?
After much convincing: whole departments are using and loving it....

Me: hey let's move from rackspace to DO!
Boss: huumm... Convince me...
Year latter: everything smooth and muuuch lower prices... Managing 6 servers instead of one...

Me: UNIT TESTS!!!
Boss: nah, this but a waste of time...

For real? Get a grip man, I only encourage solutions tested ( no pun intended, or is it ) by me for a long time...

Anyone with Jetbrains Webstorm?
Or what IDE do you use for web design/programming?

After a hard search and test work my boss finally agreed upon using YouTrack as a software management tool.

😁😁

Hey, my team is attending a hackathon kind of thing tonight. Can you recommend us some interesting php+js stacks?

I built a decently large project at work, and everything works perfectly. It's beautiful, it's fast, it's light, it's organized and clean, and deploying is a breeze. I'm very proud of it.

The biggest reason, though, is that it uses exclusively technology I had never touched before:
• React
• Redux
• ES6/Babel
• Webpack
• Express.js
• Material Design
• Apple lappy (I'm a linux girl)

I was completely new to all of these, including my dev machine. Every single aspect of the project was outside my skillet.

But it went from my first experimental `import React from 'react'` to production-ready in three weeks. I'm really proud 😊

In my hunt for the perfect productivity app I came upon something called Freeter.

It is a productivity app that lets me gather what I need for the work I'm working on, and then manage it all in one place.

For me, It's super nice to be able to check tasks in Trello, or communicating in Slack without having to change tabs or open a new browser.

Try it out and tell me what you think

I’m back for a fucking rant.

My previous post I was happy, I’ve had an interview today and I felt the interviewer acted with integrity and made the role seem worthwhile. Fuck it, here’s the link:
https://www.devrant.io/rants/889363

So, since then; the recruiter got in touch: “smashed it son, sending the tech demo your way, if you can get it done this evening that would be amazing”

Obviously I said based on the exact brief I think that’s possible, I’ll take a look and let them know if it isn’t.

Having done loads of these, I know I can usually knock them out and impress in an evening with no trouble.

Here’s where shit gets fucked up; i opened the brief.

I was met with a brief for an MVP using best practice patterns and flexing every muscle with the tech available...

Then I see the requirements, these fucking dicks are after 10 functional requirements averaging an hour a piece.

+TDD so * 1.25,
+DI and dependency inversion principle * 1.1
+CI setup (1h on this platform)
+One ill requirement to use a stored proc in SQL server to return a view (1h)
+UX/UI design consideration using an old tech (1-2h)
+unobtrusive jquery form post validation (2h)
+AES-256 encryption in the db... add 2h for proper testing.

These cunts want me to knock 15-20h of Work into their interview tech demo.

I’ve done a lot of these recently, all of them topped out at 3h max.

The job is middling: average package, old tech, not the most exciting or decent work.

The interviewer alluded to his lead being a bit of a dick; one of those “the code comes first” devs.

Here’s where shit gets realer:
They’ve included mock ups in the tech demo brief’s zip... I looked at them to confirm I wasn’t over estimating the job... I wasn’t.

Then I looked at the other files in the fucking zip.

I found 3 of the images they wanted to use were copyright withheld... there’s no way these guys have the right to distribute these.

Then I look in the font folder, it’s a single ttf, downloaded from fucking DA Font... it was published less than 2mo ago, the license file had been removed: free for Personal, anything else; contact me.

There’s no way these guys have any rights to this font, and I’ve never seen a font redistributed legally without it’s accompanying licence files.

This fucking company is constantly talking about its ethical behaviours.

Given that I know what I’m doing; I know it would have taken less time to find free-for-commercial images and use a google font... this sloppy bullshit is beyond me.

Anyway, I said I’d get back to the recruiter, he wasn’t to know and he’s a good guy. I let him know I’d complete the tech demo over the weekend, he’s looked after me and I don’t want him having trouble with his client...

I’ll substitute the copyright fuckery with images I have a license for because there’s no way I’m pushing copyright stolen material to a public github repo.

I’ll also be substituting the topic and leaving a few js bombs in there to ensure they don’t just steal my shit.

Here’s my hypotheses, anyone with any more would be greatly welcomed...
1: the lead dev is just a stuck up arsehole, with no real care for his work and a relaxed view on stealing other people’s.
2: they are looking for 15-20h free work on an MVP they can modify and take to market
3: they are looking for people to turn down this job so they can support someone’s fucking visa.

In any case, it’s a shit show and I’ll just be seeing this as box checking and interview practice...

Arguments for 1: the head told me about his lead’s problems within 20mn of the interview.
2: he said his biggest problem was getting products out quickly enough.
3: the recruiter told me they’d been “picky”, and they’re making themselves people who can’t be worked for.

I’m going to knock out the demo, keep it private and protect my work well. It’s going to smash their tits off because I’m a fucking great developer... I’ll make sure I get the offer to keep the recruiter looked after.

Then fuck those guys, I’m fucking livid.

After a wonderful interview experience and a nice introduction to the company I’ve been completely put off...

So here’s the update: if you’re interviewing for a shitty middle level dev position, amongst difficult people, on an out of date stack... you need people to want you, don’t fuck them off.

If they want my time to rush out MVPs, they can pay my day rate.

Fuuuuuuuuck... I typed this out whilst listening to the podcast, I’m glad I’m not the only one dealing with shit.

Oh also; I had a lovely discriminatory as fuck application, personality test and disability request email sent to me from a company that seems like it’s still in the 90s. Fuck those guys too, I reported them to the relevant authorities and hope they’re made to look at how morally reprehensible their recruitment process is. The law is you don’t ask if the job can be done by anyone.

So last year I sent my PC to get a motherboard replacement, as I couldn't be arsed replacing it or even research what motherboard I should get(was dealing with more urgent personal matters).

Anyway, I get it back and everything works good but not the front USB port.. I always found it weird, but also didn't bother to open the case and double check, so I let it go and assumed, since the motherboard was fried, that the USB wires were faulty.

Time passes by and I decide to open the case for annual cleaning job... Turns out the motherfucker didn't connect the port, why?? Fucks knows why... Obviously the wires were "short" and he didn't even try to pull it out further!!! You little piece of shit,for a full year I've been living with a missing usb port, the fucking front facing mother fucking usb port. Fuck.

Moral of story? Don't be a lazy ass and fix your shit on your own!

I don't use Google/Facebook for privacy reasons (and their sub-services etc). Haven't used them for ages but noticed that google still loads a lot of domains like analytics etc. This goes for facebook as well.

I now blocked a lot of google/facebook domains through my hosts file.

It's funny to see the amount of DNS requests to those fb/google connected domains nearly go to zero and also the fact that I literally can't load google/facebook anymore!

Hackers are ready...
