A senior developer come to interrupt me.

Senior developer: blah...blah....blah about this concept...... that concept... So, any new things you learn lately that you would like to share?

Me: I am learning back C++
Immediately he stop me and said, "Why did you learn C++? It is obsolete, no one use it anymore"

Me (in my head): But, you just said what I learn. It doesn't matter if its obsolete or not. Infact you are wrong, C++ is not obsolete anytime soon. I was about to share on webassembly.

Senior developer: So, would you like to join me in a short sharing session this afternoon.

Me: No thanks, I am really busy (just want to avoid at any cost)

Thus far I've had little success trying to teach code to people I know.

But yesterday.....man

My best friend told me that he was serious about learning. He asked me about my recommendation would be. Against all odds, and after small demonstrations he asked to learn about Java.

I made some coffee and braced myself. Either the dude is a hidden genius or I am an amazing instructor, but he got the whole thing. I introduced him to the basics, oop, variables etc and he got it down in one session. He was able to understand errthing a do a little code along.

So proud.

I've found and fixed any kind of "bad bug" I can think of over my career from allowing negative financial transfers to weird platform specific behaviour, here are a few of the more interesting ones that come to mind...

#1 - Most expensive lesson learned

Almost 10 years ago (while learning to code) I wrote a loyalty card system that ended up going national. Fast forward 2 years and by some miracle the system still worked and had services running on 500+ POS servers in large retail stores uploading thousands of transactions each second - due to this increased traffic to stay ahead of any trouble we decided to add a loadbalancer to our backend.

This was simply a matter of re-assigning the IP and would cause 10-15 minutes of downtime (for the first time ever), we made the switch and everything seemed perfect. Too perfect...

After 10 minutes every phone in the office started going beserk - calls where coming in about store servers irreparably crashing all over the country taking all the tills offline and forcing them to close doors midday. It was bad and we couldn't conceive how it could possibly be us or our software to blame.

Turns out we made the local service write any web service errors to a log file upon failure for debugging purposes before retrying - a perfectly sensible thing to do if I hadn't forgotten to check the size of or clear the log file. In about 15 minutes of downtime each stores error log proceeded to grow and consume every available byte of HD space before crashing windows.

#2 - Hardest to find

This was a true "Nessie" bug.. We had a single codebase powering a few hundred sites. Every now and then at some point the web server would spontaneously die and vommit a bunch of sql statements and sensitive data back to the user causing huge concern but I could never remotely replicate the behaviour - until 4 years later it happened to one of our support staff and I could pull out their network & session info.

Turns out years back when the server was first setup each domain was added as an individual "Site" on IIS but shared the same root directory and hence the same session path. It would have remained unnoticed if we had not grown but as our traffic increased ever so often 2 users of different sites would end up sharing a session id causing the server to promptly implode on itself.

#3 - Most elegant fix

Same bastard IIS server as #2. Codebase was the most unsecure unstable travesty I've ever worked with - sql injection vuns in EVERY URL, sql statements stored in COOKIES... this thing was irreparably fucked up but had to stay online until it could be replaced. Basically every other day it got hit by bots ended up sending bluepill spam or mining shitcoin and I would simply delete the instance and recreate it in a semi un-compromised state which was an acceptable solution for the business for uptime... until we we're DDOS'ed for 5 days straight.

My hands were tied and there was no way to mitigate it except for stopping individual sites as they came under attack and starting them after it subsided... (for some reason they seemed to be targeting by domain instead of ip). After 3 days of doing this manually I was given the go ahead to use any resources necessary to make it stop and especially since it was IIS6 I had no fucking clue where to start.

So I stuck to what I knew and deployed a $5 vm running an Nginx reverse proxy with heavy caching and rate limiting linked to a custom fail2ban plugin in in front of the insecure server. The attacks died instantly, the server sped up 10x and was never compromised by bots again (presumably since they got back a linux user agent). To this day I marvel at this miracle $5 fix.

Well on my last full-time job, that ware using cookies for authentication (not something new, eh?). The thing is, you see, the cookies had the 'accountId' which if you change to another number, kaboom you're that account, oh but that was not all, there was an option to mark the account type in there 'accountType', which was kind of obvious in VLE (virtual learning environment), 'Teacher', 'Student', 'Manager' put what of those values and boom you are that role for the session

Thing was open of SQL injection from the login form, from said cookies and form every part you can pass input to it, when I raised the question to my TL he said 'no one is going to know about thatt, I don't see what is the problem', then escalated to higher management 'oh well speak to *tl_guy*'

Oh and bonus points for it being written in ASP CLASSIC in 2014+ (I was supposed to rewrite, but ended up patching ASP code and writing components in PHP)

In 2015-2016, in a private college, charging kind-of big money per year

# Retrospective as Backend engineer

Once upon a time, I was rejected by a startup who tries to snag me from another company that I was working with.
They are looking for Senior / Supervisor level backend engineer and my profile looks like a fit for them.
So they contacted me, arranged a technical test, system design test, and interview with their lead backend engineer who also happens to be co-founder of the startup.

## The Interview

As usual, they asked me what are my contribution to previous workplace.
I answered them with achievements that I think are the best for each company that I worked with, and how to technologically achieve them.

One of it includes designing and implementing a `CQRS+ES` system in the backend.
With complete capability of what I `brag` as `Time Machine` through replaying event.

## The Rejection

And of course I was rejected by the startup, maybe specifically by the co-founder. As I asked around on the reason of rejection from an insider.

They insisted I am a guy who overengineer thing that are not needed, by doing `CQRS+ES`, and only suitable for RND, non-production stuffs.

Nobody needs that kind of `Time Machine`.

## Ironically

After switching jobs (to another company), becoming fullstack developer, learning about react and redux.
I can reflect back on this past experience and say this:

The same company that says `CQRS+ES` is an over engineering, also uses `React+Redux`.
Never did they realize the concept behind `React+Redux` is very similar to `CQRS+ES`.

- Separation of concern
- CQRS: `Command` is separated from `Query`
- Redux: Side effect / `Action` in `Thunk` separated from the presentation
- Managing State of Application
- ES: Through sequence of `Event` produced by `Command`
- Redux: Through action data produced / dispatched by `Action`
- Replayability
- ES: Through replaying `Event` into the `Applier`
- Redux: Through replay `Action` which trigger dispatch to `Reducer`

---

The same company that says `CQRS` is an over engineering also uses `ElasticSearch+MySQL`.
Never did they realize they are separating `WRITE` database into `MySQL` as their `Single Source Of Truth`, and `READ` database into `ElasticSearch` is also inline with `CQRS` principle.

## Value as Backend Engineer

It's a sad days as Backend Engineer these days. At least in the country I live in.
Seems like being a backend engineer is often under-appreciated.
Company (or people) seems to think of backend engineer is the guy who ONLY makes `CRUD` API endpoint to database.

- I've heard from Fullstack engineer who comes from React background complains about Backend engineers have it easy by only doing CRUD without having to worry about application.
- The same guy fails when given task in Backend to make a simple round-robin ticketing system.
- I've seen company who only hires Fullstack engineer with strong Frontend experience, fails to have basic understanding of how SQL Transaction and Connection Pool works.
- I've seen company Fullstack engineer relies on ORM to do super complex query instead of writing proper SQL, and prefer to translate SQL into ORM query language.
- I've seen company Fullstack engineer with strong React background brags about Uncle Bob clean code but fail to know on how to do basic dependency injection.
- I've heard company who made webapp criticize my way of handling `session` through http secure cookie. Saying it's a bad practice and better to use local storage. Despite my argument of `secure` in the cookie and ability to control cookie via backend.

Best part of working in Company:
Getting learning sessions from Seniors and sharing design aspects and their pros and cons.
Had an awesome session on how to focus on making a code testable.
With hands on coding too.
Never expected to have such a great experience.

v0.0005a (alpha)
- class support added to lua thanks to yonaba.
- rkUIs class created
- new panel class
- added drawing code for panel
- fixed bug where some sides of the UI's border were failing to drawing (line rendering quark)

v0.0014a (alpha) 11.30.2023 (~2 hours)
- successfully retrieving basic data from save folder, load text into lua from files
- added 'props' property to Entity class
- added a props table to control what gets serialized and what doesn't
- added a save() base method for instances (has to be overridden to be useful beyond the basics)
- moved the lume.serialize() call into the :save() method on the base entity class itself
- serialized and successfully saved an entities property table.
- fixed deserializion bugs involving wrong indexes (savedata[1] not savedata[2])
- moved deserialization from temp code, into line loading loop itself (assuming each item is on one line)
- deser'd test data, and init()'d new player Entity using the freshly-loaded data, and displayed the entity sprite

All in all not a bad session. Understanding filing handling and how to interact with the directory system was the biggest hurdle I was worried about for building my tools.

Next steps will be defining some basic UI elements (with overridable draw code), and then loading and initializing the UI from lua or json.

New projects can be set as subfolders folders in appdata, using 'Setidentity("appname/projectname") to keep things clean.

I'm not even dreading writing basic syntax highlighting!

Idea is to dogfood the whole process. UI is in-engine rendered just like you might see with godot, unity, or gamemaker, that way I have maximum flexibility to style it the way I want. I'm familiar enough with constructing from polygons, on top of stenciling, on top of nine-slicing, on top of existing tweening and special effects, that I can achieve exactly what I want.

Idea is to build a really well managed asset pipeline. Stencyl, as 'crappy' as it appeared, and 'for education' was a master class in how to do things the correct way, it was just horribly bloated while doing it.

Logical tilesets that you import, can rearrange through drag-n-drop, assign custom tile shapes to, physics materials, collisions groups, name, add tag data to, all in one editor? Yes please.
Every other 2D editor is basic-bitch, has you importing images, and at most generates different scales and does the slicing for you.

Code editor? Everything behavior was in a component, with custom fields. All your code goes into a list of events, which you can toggle on and off with a proper toggle button, so you can explicitly experiment, instead of commenting shit out (yes git is better, but we're talking solo amateurs here, they're not gonna be using git out the gate unless they already know what they're doing).

Components all have an image assignable to identify them, along with a description field, and they're arranged in a 2d grid for easy browsing, copying, modifying.

The physics shape editor, the animation editor, the map editor, all of it was so bare bones and yet had things others didn't.

I want that, except without the historic ties to flash, without the overhead of java, and with sexier fucking in-engine rendering of the UI and support for modding and in-engine custom tools.

Not really doing it for anyone except myself, and doubt I'll get very far, but since I dropped looking for easy solutions, I've just been powering through all the areas I don't understand and doing the work.

I rediscovered my love of programming after 3-4 years of learning to hate it, and things are looking up.

One of my college professor just reached out to me on Whatsapp and he told me that my college is conducting a short crash course on "Machine Learning" for students. He asked me if I could visit and take a session along with others. He also sent me an ad banner which my collage had designed for this purpose.

Soon after the chat, I just opened up Instagram and saw my privacy going for a huge toss 🤪😡!!

I love this wk108 tag. Have a lot of stories related to it.
For me , my mentors are the reason i am what i am today. In this crazy selfish world where people only want to run faster than the others, having nice helping people around is great.
(Val titanLannister=xx)

(1)class 6-10th, xx is a curious, but poor boy with no desktop/mobile , but still loves cs classes due to various ,caring teachers.
(2) class 11th end,programming for the first time that year, hates programming, one day when everybody goes out for lunch, xx tears down while talking to his cs teacher "why can't i score good marks when i was the best till 10th? Is programming so tough?" . I remember him giving me a little but greatest motivational lecture followed by 40 minutes of the most basic concepts in which i might had asked him a 1000 questions. "You are my chaempion", he used to say😂 (bad accent) . But god, if he hadn't motivated me that day, i swear i would have left all this and go for business. Thank-you, lokesh sir💗💗

First year : tried to go for a competitive learning course. Mann, am not cool in that stuff. Again was about to break (i was among the top scorers in school boards and had designed many small games back then. I should have been good here too, but nah... the other guys were like bullets .)
Oh my, my deepest bow to this amazing teacher SUMEET MALIK (oh sir, you were so good) .
How this guy taught? Well, he first explained the concept. Fo those who understood, he gave them question 'A', for those who didn't, he repated . For those who understood , can do question a again, and those eho did A already gets an even advance question B. And this cycle went on until the weakest student(usually me) understood the concept.
And no, it never happened even once that class finished with even a single child not doing all questions he gave.he used to teach very less concepts each class and would go to everybody's desk to check they understood the concept, the question, its working, weather we implemented or not and weather our implementation is correct or not +our doubts. Hell , i even took doubts with him for hours after the class and he always just smiled💗(oh sir, am so sorry for being so dumb)
Real Doubt classes, doubts on whatsApp, revision assignments , tests , competitions,... damn, i haven't seen a teacher with this much dedication. At one point of time, that institution was famous for our Sumeet sir's classes 😂

Then last year, i got another mentor . Harshit bhiya. The guy is awesome, and a little extra swaggy 😂. He got a lot of chill, with his big AAD badge, a bag full of stickers and his every day association with people at udacity and google. As always i tried to overwhelm him with my ton of doubts in class, but he use to just give me a few pointers/links, after which i was like quiet for the complete session😂. He gave me a lot to think/work upon and i got a kind of career to work on.

I also think of mentioning a fucked up depressing-bot assholic friend of mine, but he don't deserve to be in this list of my best people. Just fuck you mann with a blockchain of dicks, if you are reading this.

Even though I’ve been working through a C# book about WinForms, which I’m half way done with, I still don’t feel like I’m working productively and I hate the negative feeling it’s giving me.

It’s going to sound stupid but it’s making me feel like I’m not spending enough time programming even though I’ve been programming quite a bit this week. I mean the small apps aren’t practical they’re just for learning how it all works but still. Im not reading the book for learning the programming logic it’s for the WinForms knowledge.

I think it’s just that I want to make progress on my main project and just have a 4+ hour coding session.

In school,our c++ teacher gave an list of programs we had to do in lab that annual session,i was excited about learning programming so i strtrd reading my c++ book & completed all those programs in less than a month......

I provide training for our clients on our company CMS after having built them their sites.

I once had 3 ladies could me in for their FREE training session who were incredibly rude. They I territories me mid sentence to talk about unrelated stuff, spoke over me, were clearly uninterested in learning the system, and devolved the meeting into their own board meeting.

I didn't know how to deal with such rudeness without being rude back long story short they left having learned nothing, too dumb to work the system out themselves and I find ways to be unhelpful each time they ring up to ask for support they haven't paid for...

Looks like unzipping on disk drive where you keep your dataset can crash machine learning training session.
Thanks nvidia for your great drivers.
I like your solutions.

27 days ago I asked here for advice on how to mentor software engineer student that was terrible at coding.

So, we are in the middle of the mentoring, my approach is for her to get used to normal engineering tools, in this occasion she is learning Git and "kanban" (basically we are using Clubhouse for this one) and Github PR submission and approval (I'm the one who approves them, naturally) by doing.

With git, things are hard because we cannot share a terminal session (via upterm) due to her using Windows on her laptop (WSL is an option for using upterm but her internet is so damn slow doing the configuration takes way too long), otherwise teaching her use git would be smoother than it is currently, with the other tools she is gaining a good grasp of them, it pleases me that the bottleneck is with Git itself.

She is working on a hangman game with Python, nothing fancy just the terminal. I made the stories with the requirements in Clubhouse for her to work on each as a unit removing some "thought process" of reading requirements and implementing solutions (at Uni it seems the professor writes a document of several pages detailing the background of the project and the requirements, I can see how it can become confusing for some students like her).

She will start Uni again this August 10th, there is a chance that our first "session" at this will end by then, my fear is that she forgets how to use the tools she learned, so I need to find a way to encourage her to keep using them somehow.

Dell Summer Internship Experience 

Firstly,to be a part of this process it is important to clear the exam conducted by college and according to me it wasn't something which can't be easily achieved so to prepare of this exam stick to basics of all subjects which have been taught so far till semester majorily data structures,data base,Java,C, operating system were asked.Basics of all following subjects should be clear which also going to help during internship.I myself prepared for the test from geeksforgeek.I tried to gain as much as basic knowledge of subjects I can.And after selecting from test you have you go through hackathon on that personally I think one should be prepared with latest demanding skills.Mostly all the hackathon topics were in and around Machine Learning,Block chain,Web development,Databases.So typically should be aware of all these technologies and how this can be used to enhance in project.During hackathon days it is important to be interactive,it  is good to clear doubts or explain your idea and how innovative you project is and how different it can be and further keep in mind how your project can be industrial utilized.Try to make your project more in aspect of how industry going to adapt this or how this problem's solution is perfect in every terms for a company.And majorily at last it comes down to how to present your project infront of your panel.I think keep that session as much as interactive you can,try to answer their queries,and most importantly know your part of the project very well on theoretical as well as on code level. At last you have to go through a HR interview in which firstly you have to be prepare with a nice resume in which you to include all your achievement's,projects and most importantly keep it short and simple and include only those things which you are completely aware of.For interview first try to know and learn about company, it's goals,in what field it is presently working and during interview there is nothing to worry about you just have to talk like you are talking with a normal person,express all your views ,try to speak out. Confidence is one important thing for this interview.So this was conclusion of my experience from hackathon hiring process from Dell.

## Learning k8s

Interesting. So sometimes k8s network goes down. Apparently it's a pitfall that has been logged with vendor but not yet fixed. If on either of the nodes networking service is restarted (i.e. you connect to VPN, plug in an USB wifi dongle, etc..) -- you will lose the flannel.1 interface. As a result you will NOT be able to use kube-dns (because it's unreachable) not will you access ClusterIPs on other nodes. Deleting flannel and allowing it to restart on control place brings it back to operational.

And yet another note.. If you're making a k8s cluster at home and you are planning to control it via your lappy -- DO NOT set up control plane on your lappy :) If you are away from home you'll have a hard time connecting back to your cluster.
A raspberry pi ir perfectly enough for a control place. And when you are away with your lappy, ssh'ing home and setting up a few iptables DNATs will do the trick

netikras@netikras-xps:~/skriptai/bin$ cat fw_kubeadm
#!/bin/bash

FW_LOCAL_IP=127.0.0.15
FW_PORT=6443
FW_PORT_INTERMED=16443
MASTER_IP=192.168.1.15
MASTER_USER=pi

FW_RULE="OUTPUT -d ${MASTER_IP} -p tcp -j DNAT --to-destination ${FW_LOCAL_IP}"

sudo iptables -t nat -A ${FW_RULE}

ssh home -p 4522 -l netikras -tt \
-L ${FW_LOCAL_IP}:${FW_PORT}:${FW_LOCAL_IP}:${FW_PORT_INTERMED} \
ssh ${MASTER_IP} -l ${MASTER_USER} -tt \
-L ${FW_LOCAL_IP}:${FW_PORT_INTERMED}:${FW_LOCAL_IP}:${FW_PORT} \
/bin/bash
# 'echo "Tunnel is open. Disconnect from this SSH session to close the tunnel and remove NAT rules" ; bash'

sudo iptables -t nat -D ${FW_RULE}

And ofc copy control plane's ~/.kube to your lappy :)

I think I'm a good hackhands expert.

If there's something I don't understand, I pause the session, and I do my research.
If a client is learning, I'll pause whenever they have a question, and explain in depth so they get the concept.

But the asshole that I worked with today just didn't understand how debugging works. I try one fucking thing that doesn't immediately work (after I already identified the root of his problem), and, as I PAUSED and start adding debugging for him, he ends the session and leaves first a one star review saying nothing, and then a three star review saying "couldn't fix my problem"

Fuck that guy.

I wrote my first proper promise today

I'm building a State-driven, ajax fed Order/Invoice creation UI which Sales Reps use to place purchases for customers over the phone. The backend is a mutated PHP OSCommerce catalog which I've been making strides in refactoring towards OOP/eliminating spahgetti code and the need for a massive bootstrapper file which includes a ton of nonsense (I started by isolating the session and several crucial classes dealing with currency, language and the cart)

I'm using raw JS and jquery with copious reorganization.

I like state driven design, so I write all my data objects as classes using a base class with a simple attribute setter, and then extend the class and define it's attributes as an array which is passed to the parent setter in the construct.

I have also populateFromJson method in the parent class which allows me to match the attribute names to database fields in the backend which returns via ajax.

I achieve the state tracking by placing these objects into an array which underscore.js Observe watches, and that triggers methods to update the DOM or other objects.

Sure, I could do this in react but
1) It's in an admin area where the sales reps using it have to use edge/chrome/Firefox
2) I'm still climbing the react learning curve, so I can rapid prototype in jquery faster instead of getting hung up on something I don't understand
3) said admin area already uses jquery anyway
4) I like a challenge

Implementing promises is quickly turning messy jquery ajax calls into neat organized promise based operations that fit into my state tracking paradigm, so all jquery is responsible for is user interaction events.

The big flaw I want to address is that I'm still making html elements as JS strings to generate inputs/fields into the pseudo-forms.

Can anyone point me in the direction of a library or practice that allows me to generate Dom elements in a template-style manner.

Hi friends!
I'm I'll since Sunday and my imagination is starting to fade. So far I've read/watched movies on deep learning and CNN, had a long session on Wikipedia on common fallacies, as well as a lot of other things. But now I can't think of what to do.
What is your favourite go to thing when you need to kill time using nothing but eyes and ears?
I'm too tired to code or play games...

Learning power shell for a "shutdown in X hours"-script and windows batch for scripts to start all my games that might need to auto-update, so I could start the next session faster and one to start all games with daily login rewards.

Hey Everyone, first of all I’d like to start with my usual, hope all is well today as always! Today I’d like to post my first official rant.... so anyone that knows me in person or in general knows me as a good helpful young man, right now Milo is happy but has the urge to rant..

So... not naming anyone specifically from uni... one person specifically always on Facebook messaging me for my assessments, now me being me i try to say No, but the issue is i want people to do well, i put my heart into my work and people just want assignments handed to them on a gold platter, it takes me a lot longer to try and get concepts around my head , I usually always stay up late nights to get a better understanding of things. As you may see my work means a lot to me.

I always mention to my friends if they wish to do well, they must sacrifice going out clubbing or other social things for a later time. I spend my majority of the week learning new things related to programming Monday - Saturday, and on Sunday i have my free time , with the usual work out session thrown inbetween :-).

So anyways, thats it for my rant, I’d love to know if anyone has been through a similar instance? If so would love to hear about it!.

Thank you for taking the time to read my long rant once again :-)

Milo 🥂☺️

hi guys so i'll be having a tutorial session tomorrow about java programming(not my choice) and im looking for scratch(like) game or any block programming games that can have classes with methods and properties. btw i want to use block type programming first before getting into hard coding because (at least i think) it can help ease the learning curve, it will help understanding about the concepts first without the pressure of remembering syntax. any recommendations?

I've been planning a startup project for months now. Then, what was a supposedly simple quest of finding out whether session-based or token-based authentication is better, has become a question of whether I should setup my own OpenID Connect (IODC) auth server or stick to simpler methods.

I've already spent almost a week learning OAuth2 and OIDC, and I can't tell whether this route is an overkill for my usecase. (Or that I just don't want to admit I'm falling into the shiny tech trap.)

How about you guys, how would you approach authentication? JWT/JWE? Sessions?

Learning to like manjaro, a lot, setting up i3 for a workstation and kubernetes cluster with a couple of manjaro workstations with just the cli installed... few gotchas on the way, get Hyper-V enhanced mode working but get a message session error on dbus launch - easy fix it is already launched by lightdm, the cli install doesn't start the network driver by default but can get a whole 3 node k8s cluster running in under an hour from scratch and forward i3 to a nice, fast, little windows x-server that I got for free with Microsoft reward points.. winning!

hey, so i have recently started learning about node js and express based backend development.

can you suggest some good github repositories that showcase real life backend systems which i can use as inspiration to learn about the tech?

like for eg, i want to create a general case solution for authentication and profile management : a piece of db+api end points + models to :

- authenticate user : login/signup , session expire, o auth 2 based login/signup, multi account login, role based access, forgot password , reset password, otp login , etc

- authorise user : jwt token authentication, ip whitelisting, ssl pinning , cors, certificate based authentication , etc (

- manage user : update user profile, delete user, map services , subscriptions and transactions to user , dynamic meta properties ( which can be added/removed for a single user and not exactly part of main user profile) , etc

followed by deployment and the assoc concepts involved : deployment, clusters, load balancers, sharding ,... etc

----

these are all the buzzwords that i have heard that goes into consideration when designing a secure authentication system for a particular large scale website like linkedin or youtube. am not even sure how many of these concepts would require actual codelines and how many would require something else.

so wanted inspiration from open source content to learn about it in depth, replicate and create new better stuff if possible .

apart from that, other backend architectures like video/images storage system, or just some server for movie, social media, blog website etc would also help.
