Biggest scaling challenge I've faced?

Around 2006~2007 the business was in double-digit growth thanks to the eCommerce boom and we were struggling to keep up with the demand.

Upper IT management being more hardware focused and always threw more hardware at the problem. At its worst, we had over 25 web servers (back then, those physical tall-rectangle boxes..no rack system yet) and corresponding SQL server for each (replicated from our main sql server)

Then business boomed again and projected the need for 40 servers (20 web servers, 20 sql servers) over the next 5 years. Hardware+software costs (they were going to have to tear down a wall in order to expand the server room) were going to be in the $$ millions.

Even though we were making money, the folks spending it didn't seem to care, but I knew this trajectory was not sustainable, so I started utilizing (this was 2007) WCF services and Microsoft's caching framework Velocity. Started out small, product lookup data (description, price, the simple stuff) and within a month, I was able to demonstrate the web site could scale with less than half of our current hardware infrastructure.

After many political battles (I've ranted about a few of those), the $$ won and even with the current load, we were able to scale back to 5 web servers and 2 sql servers. When the business increased in the double-digits again, and again...we were still the same hardware for almost 5 years. We only had to add another service server when the international side of the business started taking off.

Challenge wasn't the scaling issue, the challenge was dealing with individuals who resisted change.

Worst dev team failure I've experienced?

One of several.

Around 2012, a team of devs were tasked to convert a ASPX service to WCF that had one responsibility, returning product data (description, price, availability, etc...simple stuff)
No complex searching, just pass the ID, you get the response.

I was the original developer of the ASPX service, which API was an XML request and returned an XML response. The 'powers-that-be' decided anything XML was evil and had to be purged from the planet. If this thought bubble popped up over your head "Wait a sec...doesn't WCF transmit everything via SOAP, which is XML?", yes, but in their minds SOAP wasn't XML. That's not the worst WTF of this story.

The team, 3 developers, 2 DBAs, network administrators, several web developers, worked on the conversion for about 9 months using the Waterfall method (3~5 months was mostly in meetings and very basic prototyping) and using a test-first approach (their own flavor of TDD). The 'go live' day was to occur at 3:00AM and mandatory that nearly the entire department be on-sight (including the department VP) and available to help troubleshoot any system issues.

3:00AM - Teams start their deployments
3:05AM - Thousands and thousands of errors from all kinds of sources (web exceptions, database exceptions, server exceptions, etc), site goes down, teams roll everything back.

3:30AM - The primary developer remembered he made a last minute change to a stored procedure parameter that hadn't been pushed to production, which caused a side-affect across several layers of their stack.

4:00AM - The developer found his bug, but the manager decided it would be better if everyone went home and get a fresh look at the problem at 8:00AM (yes, he expected everyone to be back in the office at 8:00AM).

About a month later, the team scheduled another 3:00AM deployment (VP was present again), confident that introducing mocking into their testing pipeline would fix any database related errors.

3:00AM - Team starts their deployments.
3:30AM - No major errors, things seem to be going well. High fives, cheers..manager tells everyone to head home.
3:35AM - Site crashes, like white page, no response from the servers kind of crash. Resetting IIS on the servers works, but only for around 10 minutes or so.
4:00AM - Team rolls back, manager is clearly pissed at this point, "Nobody is going fucking home until we figure this out!!"
6:00AM - Diagnostics found the WCF client was causing the server to run out of resources, with a mix of clogging up server bandwidth, and a sprinkle of N+1 scaling problem. Manager lets everyone go home, but be back in the office at 8:00AM to develop a plan so this *never* happens again.

About 2 months later, a 'real' development+integration environment (previously, any+all integration tests were on the developer's machine) and the team scheduled a 6:00AM deployment, but at a much, much smaller scale with just the 3 development team members.

Why? Because the manager 'froze' changes to the ASPX service, the web team still needed various enhancements, so they bypassed the service (not using the ASPX service at all) and wrote their own SQL scripts that hit the database directly and utilized AppFabric/Velocity caching to allow the site to scale. There were only a couple client application using the ASPX service that needed to be converted, so deploying at 6:00AM gave everyone a couple of hours before users got into the office. Service deployed, worked like a champ.

A week later the VP schedules a celebration for the successful migration to WCF. Pizza, cake, the works. The 3 team members received awards (and a envelope, which probably equaled some $$$) and the entire team received a custom Benchmade pocket knife to remember this project's success. Myself and several others just stared at each other, not knowing what to say.

Later, my manager pulls several of us into a conference room
Me: "What the hell? This is one of the biggest failures I've been apart of. We got rewarded for thousands and thousands of dollars of wasted time."
<others expressed the same and expletive sediments>
Mgr: "I know..I know...but that's the story we have to stick with. If the company realizes what a fucking mess this is, we could all be fired."
Me: "What?!! All of us?!"
Mgr: "Well, shit rolls downhill. Dept-Mgr-John is ready to fire anyone he felt could make him look bad, which is why I pulled you guys in here. The other sheep out there will go along with anything he says and more than happy to throw you under the bus. Keep your head down until this blows over. Say nothing."

My code review nightmare part 3

Performed a review on/against a workplace 'nemesis'. I didn't follow the department standards document (cause I could care less about spacing, sorted usings, etc) and identified over 80 bugs, logic errors, n+1 patterns, memory leaks (yes, even in .net devs can cause em'), and general bad behavior (ex.'eating' exceptions that should be handled or at least logged)

Because 'Jeff' was considered a golden child (that's another long TL;DR), his boss and others took a major offense and demanded I justify my review, item by item.

About 2 hours into the meeting, our department mgr realized embarrassing Jeff any further wasn't doing anyone any good and decided to take matters into his own hands. Thinking 'well, its about time he did his job', I go back to my desk. About an hour later..
Mgr: "I need you in the conference room, RIGHT NOW!"
<oh crap>
Mgr: "I spoke to Jeff and I think I know what the problem is. Did you ever train him on any of the problems you identified in the review?"
Me: "Um, no. Why would I?"
Mgr: "Ha!..I was right. So lets agree the problems are partially your fault, OK?"
Me: "Finding the bugs in his code is somehow my fault?"
Mgr: "Yes! For example, the n+1 problem in using the WCF service, you never trained him on how to use the service. You wrote the service, correct?"
Me: "Yes, but it's not my job to teach him how to write C#. I documented the process and have examples in the document to avoid n+1. All he had to do was copy/paste."
Mgr: "But you never sat with Jeff and talked to him like a human being? You sit over there in your silo and are oblivious to the problems you cause. This ends today!"
Me: "What the...I have no idea what you are talking about. What in the world did Jeff tell you?"
Mgr: "He told me enough and I'm putting an end to it. I want a compressive training class developed on how to use your service. I'll give you a month to get your act together and properly train these developers."

3 days later, I submit the power-point presentation and accompanying docs. It was only one WCF with a handful of methods. Mgr approved the training, etc..etc. execute the 'training', and Jeff submits a code review a couple of weeks later. From over 80 issues to around 50. The poop hits the fan again.

Mgr: "What's your problem? When are you going to take your responsibility seriously?"
Me: "Its pretty clear I don't have the problem. All the review items were also verified by other devs. Its not me trying to be an asshole."
Mgr: "Enough with the excuses. If you think you can do a better job *you* make the code changes and submit them for Jeff for review. No More Excuses!"

Couple of days later, I make the changes, submit them for review, and Jeff really couldn't say too much other than "I don't see this as an improvement"

TL;DR, I had been tracking the errors generated by the site due to the bugs prior to my changes. After deployment, # of errors went from thousands per hour to maybe hundreds per day (that's another story) and the site saw significant performance increases, fewer customer complaints, etc..etc.

At a company event, the department VP hands out special recognition awards:

VP: "This award is especially well earned. Not only does this individual exemplify the company's focus on teamwork, he also went above and beyond the call of duty to serve our customers. Jeff, come on up and get this well deserved award."

Developer came to our area to rant a bit about a problem he was having with Xamarin. A particular android device was receiving a java runtime error trying to de-serialize data from a WCF contract. What he found was not to use WCF and use WebAPI (or a simple REST service that sent back/forth JSON).

When he proposed changing the service (since the data transport didn’t really matter, he could plug the assembly into a WebAPI project in less than an hour), the dev manager shot down the idea pointing him to our service standard that explicitly stated no WebAPI (it’s in bold letters).

I showed him the date on the “standard”, which was 5 years ago. We have versioning on our sharepoint server, so I also him my proposal notes on the change request document (almost two years before that) stating we should stop using WCF in favor of REST based web standards. Dev manager at the time had wrote in his comment “Will never use REST. Enterprise developers prefer RPC.”
He just about fell over laughing when I showed him this gif.

I'm an idiot. I freely admit this. I spent a solid 3 hours on a new endpoint in a WCF service, only to have it looked upon and told to fix it. I knew that the service I was calling didn't work like that. I did, I knew it. I didn't think about it while coding the endpoint, but I knew it. At least the changes only needed to happen in one file, and only took about 25 minutes with tests and all. But damn it, I knew better. I looked at my buddy, straight in the eye, and told him "Told you I was an idiot." He laughed, I laughed, the table laughed, we killed the table. It was a great time!

I'm a backend (Java, Kotlin) developer and I mainly design & develop services and Android apps which consume these services.

My team in my current organization (I've been working here since past 2 years) just got merged with another team.

And now the new boss wants me to fix some fuck ups in their project which is written in C#, with some WCF and other stuff.

As this stuff is completely new for me, I asked for some time to get familiar with the environment. But the answer was a big NO.

As a result, "I've started looking out for a new job"
😡😠

Fuckin management screws up everything!

During interview :
We are going build the next big thing. We are going to use the latest and greatest, now tell me what WCF and SOAP are.

*Releases software for State project comprising of a solution with 3 WinServices and 2 WCF Services*

Echo "Hello world"
Echo "Hello devrant"

Conversation yesterday (senior dev and the mgr)..

SeniorDev: "Yea, I told Ken when using the service, pass the JSON string and serialize to their object. JSON eliminates the data contract mismatch errors they keep running into."
Mgr: "That sounds really familiar. Didn't we do this before?"
SeniorDev: "Hmmm...no. I doubt anyone has done this before."
Me: "Yea, our business tier processor handled transactions via XML. It allowed the client and server to process business objects regardless of platform. Partners using Perl,
clients using Delphi, website using .aspx, and our SQLServer broker even used it."
Mgr: "Oh yea...why did we stop using it?"
Me: "WCF. Remember, the new dev manager at the time and his team broke up the business processor into individual WCF services."
Mgr: "Boy, that was a crap fest. We're still fighting bugs from the mobile devices. Can't wait until we migrate everything to REST."
SeniorDev: "Yea, that was such a -bleep-ing joke."
Me: "You were on Jake's team at the time. You were the primary developer in the re-write process saying passing strings around wasn't the way true object-oriented developers write code.
So it's OK now because the string is in JSON format or because using a JSON string your idea?"

SeniorDev turns around in his desk and puts his headphones back on.

That's right you lying SOB...I remember exactly the level of personal attacks you spewed on me and other developers behind our backs for using XML as the message format.

Keep your fat ass in your seat and shut the hell up.

Management directed a 2-month project including 5 developers, 3 DBAs, plus Q&A to replace a SOAP service that retrieved data from a single table. End result, project lasted 9+ months, 5 spectacular failed 3:00AM deployments, and a WCF service that retrieved data from a single table. Justification? Management wanted to eliminate SOAP, because SOAP uses XML and XML is slow. Thank goodness no one opened up Fiddler to see how WCF communicates.

"This is your last chance. After this, there is no turning back. You take the blue pill - the story ends, you wake up in your bed and believe whatever you want to believe. You take the red pill - you stay in Wonderland and I show you how deep the rabbit-hole goes."

Said to a new team member before they embarked on a journey of pain as I took them through a huge web app made with jQuery (think: 10K lines of DOM manipulation horror), WCF, and sadness.

Worst architecture I've seen?

The worst (working here) follow the academic pattern of trying to be perfect when the only measure of 'perfect' should be the user saying "Thank you" or one that no one knows about (the 'it just works' architectural pattern).

A senior developer with a masters degree in software engineering developed a class/object architecture for representing an Invoice in our system. Took almost 3 months to come up with ..

- Contained over 50 interfaces (IInvoice, IOrder, IProduct, etc. mostly just data bags)
- Abstract classes that implemented the interfaces
- Concrete classes that injected behavior via the abstract classes (constructors, Copy methods, converter functions, etc)
- Various data access (SQL server/WCF services) factories

During code reviews I kept saying this design was too complex and too brittle for the changes everyone knew were coming. The web team that would ultimately be using the framework had, at best, vague requirements. Because he had a masters degree, he knew best.

He was proud of nearly perfect academic design (almost 100% test code coverage, very nice class diagrams, lines and boxes, auto-generated documentation, etc), until the DBAs changed table relationships (1:1 turned into 1:M and M:M), field names, etc, and users changed business requirements (ex. concept of an invoice fee changed the total amount due calculation, which broke nearly everything).

That change caused a ripple affect that resulted in a major delay in the web site feature release.

By the time the developer fixed all the issues, the web team wrote their framework and hit the database directly (Dapper+simple DTOs) and his library was never used.

A few years ago, i had a task to implement a webservice of an insurance-company into our .NET Development.

The security requirements of this insurance-company webservice were top notch.
As a client you had to build a request that used a negotiated certificate, canonical header structures, security timestamp, a secret token in header, ...

To configure all this stuff via web.config WCF was pure pain in the ass.

After many phonecalls and emails, i finally managed to meet all security requirements to send a valid request.

First, i didn't recognized my breakthrough, because my client still had thrown exceptions while calling the insurance-webservice.

Why was that?

The exception told me on the most possible gentle way, that .Net isn't able to process an unsecured response, when there was a secured request before.

So there was top notch security for requesting, but dumbass unsecured responding with all the precious customer information.

*epicfacepalmnuclearexplosionfollowing*

I even had to raise the. Net Version of our. Net client, because i wasn't able to configure that it is allowed to process an unsecured response after using a secured request.

Whyyyyyyy?!!?!!1el even!?!

I did something potentially extremely stupid today

In 2020 when I was a teenager I suggested my uncle who ran a family business with my father to start a e commerce website. I did lot of stupid stuff doing this too. Planned to use AWS free tier to host the website and used Godaddy for domains IIRC. Setup godaddy email forwarding to his gmail account too IIRC

I registered a AWS account with my email(bad idea since my uncle's debit card was the payment method). I then setup a EC2 instance but instead of using the free instance I used some other instance because I didn't read what instance was free and setup his debit card as the payment method.

Setup woocommerce on it and pointed the domain to instance's static IP. We didn't do a lot of stuff on the website but next month on AWS we got a bill but it was a small amount. Uncle paid the bill and I terminated the EC2 instance IIRC. Next month there was a very small bill I don't remember what I did after it.

Today I remembered about it logged in to AWS and paid the bill. The problem is I used the default billing address which is in my uncle's name and the address of the family business. IIRC we didn't give them tax details of the business so we can't claim tax credit on it.

But still since there is a bill with the address of the business which Amazon probably reported to the government there could be tax discrepancies. Bill was due 4 years ago so maybe it will affect his 2020 returns which could be painful. The bill was also paid by me not from my Uncle's account so that might complicate things.

Thankfully the surprise AWS bill had basically zero affect on my relationship with my uncle.

Today I spent 9 hours trying to resolve an issue with .net core integration testing a project with soap services created using a third party soap library since .net core doesn't support soap anymore. And WCF is before my time.

The tests run in-process so that we can override services like the database, file storage, basically io settings but not code.

This morning I write the first test by creating a connected service reference to generate a service client. That way I don't need to worry about generating soap messages and keeping them in sync with the code.

I sent my first request and... Can't find endpoint.

3 hours later I learn via fiddler that a real request is being made. It's not using the virtual in-process server and http client, it's sending an actual network request that fiddler picks up, and of course that needs a real server accepting requests... Which I don't have.

So I start on MSDN. Please God help me. Nope. Nothing. Makes sense since soap is dead on .net core.

Now what? Nothing on the internet because above. Nothing in the third party soap library. Nothing. At this point I question of I have hit my wall as a developer.

Another 4 hours later I have reverse engineered the Microsoft code on GitHub and figured out that I am fucked. It's so hard to understand.

2 more hours later I have figured out a solution. It's pure filth..I hide it away in another tooling project and move all the filth to internal classes :D the equivalent of tidying your room as a kid by shoving it all under the bed. But fuck it.

My soap tests now use the correct http client with the virtual server. I am a magician.

WCF doesn't like me adding to lists...

I have to make an uno game that supports multiplayer with WCF for school...

I have a player class that has a list of card classes.

I have a function called dealHand, it adds Cards to the hand list...

I also have a callback function for updating my wpf gui...

For whatever reason if when the gui calls dealhand and I try to use myList.add(new Card()) then the updategui function in my wpf client doesn't fire...

But if I take a seperate method called makeHand which returns a list of cards, and just do myList = makeHand() then that works fine...

Never been so baffled/cursed so much at code before... Is there something about Lists that WCF doesn't like? Seriously... was weird...

Hopefully that was somewhat coherent...

I love C# and WPF, but hate WCF.

Are airwaves cast by WiFi and cell towers dangerous. Please link a credible source for it. During lunch my father brought up the fact that a actress sued the Indian government asking them to announce of 5g is dangerous or not. I said that it is not dangerous since we get higher amounts of radiation at us every day so 5g should not be anything dangerous for us. I should have said that it is non ionising radiation though. He also brought up that fact that there have been numerous instances of misleading advertising saying that what we use at our home is bad like saying ghee causes cholesterol which is bad and then a few years later saying that ghee is actually good. He just believes that companies could be doing false advertising saying that 5g is good when it actually is not. Can't blame him since he has seen multiple instances of false advertising.

Digging up on Google landed me on a nytimes article which basically said radiation 5g airwaves not effect us since our skin reflects that off and the small amount that does not get reflected heats up our skin to a negligible amount

TL Dr :- Debugging a software I barely know about was slow and ended up breaking in the shop it was used in and reverting the changes does not solve the problem

I asked my father a few days ago why he was buying a dedicated server for his ERP software and not using a client computer as his server which he is doing in his shop currently. He said that it was slow on other computers in the LAN which is an wired. The solutions given by the company that made it did not work. Big bills would sometimes also dissapear which took around 30 minutes to make. So when he bought the computer to home during lockdown I pulled up the debugging guide from the company which summed up to check latency,ram and add these files to exclusion list of your antivirus. Latency was kinda high at the first when pinging another computer on the LAN but I was testing on WiFi so it could be pretty inaccurate. The computer met the ram requirements so that was not a problem. I checked the data path by opening the software and accidentally typed something but I did not worry since the changes needed to be manually accepted. I added the files to the Windows defender exclusion list and shut it down.

Next day :- My father calls me up and says the software is working on the server but is broken on other computers. So I check if the changes were automatically accepted for some reason and yes that happened. So so pull up a guide to configure the software in multi user mode and I replace the mistyped setting with the correct one and it still does not work. My father asks me to undo everything by using anydesk. I remove all the exclusions I added to Windows defender and disable windows firewall. Still does not work. Restart the computer and software. Still does not work. Check permissions on data folder. They are correct.

WTF I reverted all the changes I made and the software does not work on other computers.

I work daily on a project, in which, rather than buy in a decent message bus a bunch of half interested, unqualified developers were tasked with hammering together an in-house solution. This monstrosity has around six layers of abstraction, separate objects per project and dynamically loading converters between the components. It's largely not unit testable, certainly not integration testable and has already wasted more money in developer time and Bugfixes than a half decent external solution would have cost.

Every time I have to change an object in one part, start the associated web/win service and do a "update service references" I die a little inside.

There are so many better ways but we'll never be able to change because "there's no time for that"

And all for some up front savings

Sent a CV for a full-stack C# role. The CV is mainly a mix of working in ASMX/WCF, SQL, SSRS, SSIS, Distributed transaction architectures then with about 40% ASP.NET focusing on server side but also with some client side technologies and that I sometimes use Illustrator for creating/manipulating SVGs.
Was told I am too "front-end"

s it just me that finds WCF cumberlicated? I'm having trouble to get my client up and running every time we set up some sort of new service solution at work. All these service references and classes that cannot be resolved just cause a meltdown in my head. GGGGGGGGGGGGGNNNNNNNNNNNNNNHHHHHHHHHHHH! *going mad*

What is your wishlist for things that need to die or change next year. Mine is :-
1. Games that use peer to peer and have servers for data. Please buy servers on aws or any good cloud service.

2. ISP's that block all incoming connections for security

Nothing like changing state contract ws-security polices to make your eyes bleed and your brain melt with symmetric encryption binding in WCF services

This kind of question has been asked before.

Is coding on mobile actually a plausible idea or should I just leave the idea. I am mostly doing some c# with .net core. It is mostly console apps

I wont have access to my laptop for quite a while because I spent quite a lot of my free time on my laptop. Also me being dumb refused their offer of 1 hour of continuous access to the laptop every day.

Duuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuck off you bloody infamous basterds flattening their fat asses at Microsoft.

I wasted half of my dev day to configure my wcf rest-api to return an enumeration property as string instead of enum index as integer.

There is actually no out-of-the-box attribute option to trigger the unholy built-in json serializer to shit out the currently set enum value as a pile of characters clenched together into a string.

I could vomit of pure happiness.

And yes.
I know about that StringEnumConverter that can be used in the JsonConvert Attribute.

Problem is, that this shit isn't triggered, no matter what I do, since the package from Newtonsoft isn't used by my wcf service as a standard serializer.

And there is no simple and stable way to replace the standard json serializer.

Christ, almighty!

I have wpf clients that connect to a service, they connect fine but for whatever reason my callback isn't firing to update the gui... the thing is though, it was firing earlier (mind you when it fired off I ended up getting null references)

I fixed the null references (turns out I wasn't serializing stuff that needed serializing) but now my updategui method just doesn't fire, period. zero exceptions are being thrown, zero errors are being given...

At this point I might just rewrite the whole thing until it breaks so I can figure out what broke it... Like trying to debug something with zero errors/exceptions being thrown is hard...

Was curious abut how painfu to work with and deploying .net core, asp.net core, blazor and xamarin are. I am currently learning c# and I have heard stuff such as ".net is a dumpster fire" and xamarin has had pretty negative reviews. Is that stuff true

I always try to make problems more ... interesting, fancy, challenging. As soon as it gets boring, my mind is wandering.

Like now, when I wrote like a gazillion stored procedures, connected them to the back end classes, connected them to the new WCF service methods, connected them to the front end ... That's when I try to do anything but work.

Debugging a WCF app and could for the love of it not get its main window up. Then I realized it was freaking Photoshop that placed itself on top of it. PS is great for editing images, but has useless management of windows and memory, at least on Windows, originally developed for Mac as it is.

What should i use for making a app which needs to learn on both android and windows and maybe ios. It is pretty simple. Mainly needs notification, network and file acccess, does not cost an arm and a leg, uses less than 1 gb of memory at a time and being able to be used as to make a backend is a plus. Being able to be used commercially is a plus too. Also please suggest somehing that does not have a steep learning curve

Any tips to speed up wordpress site. I have googled and tried as many solutions I can except adding cdn. I have minified images, html, css and js. I have used caching on the server with litespeed cache. There are not many plugins on the site.

The plugins installed are elementor, litespeed, orbit fox, wp-optimize, updraft plus and wpforms lite. The site takes around 4 to 5 seconds to fully load. I am doing this for a releative(don't worry he is sane and I am doing pretty simple stuff for him which is simply not worth charging). I cannot use cloudflare cdn since they need nameserver access and the hosting service used is hostinger which have put a lot of dns records which I don't understand and don't wanna mess with unless it is the last option.

Sorry if this has been been asked before and asking useless questions

Is there a way to compile a game for Windows from Linux in Unreal engine? I did google some posts but the answer was either use a Virtual machine which will not be done or use the the theoretical method of using mingw but the forum posts state that it will be tricky business or use a windows machine. I have dual booted windows with linux on my machine.

However since the machine has a 512 gb ssd most of the storage space is devoted to unreal engine which takes 47 gigs in itself and have a lot of programs installed I have a usable 20 gigs left out of 145 gig partition. Windows has around 318 gigs of storage to it but I have 100 gigs free at most. So after installing the windows sdk, visual studio with extensions, unreal engine and some other stuff I don't have much space left for myself. I need that much space since I install a lot of games to my ssd. So now I cant load my bigger projects for playing on my windows. I could use my hdd which is mostly used for backups and 100+ gig stuff. Though the hdd's are of course far slower than ssd's which shouldn't be a problem however last time I used visual studio it ate more than 2 gigs of ram for a solution meaning that the compiler has very low memory for itself to actually compile so for any large files the hdd has more of a bottleneck.

Oh and I can't upgrade my ssd's or ram because I don't have enough money.

Thanks for the answers in advance

Dumb question
What are some good companies for consumer networking equipment. I need a unmanaged switch and might buy a router from them. There will be 7 cables run though it. I have heard praises for ubiquiti but mostly from U.S. youtubers and I live in India so service might defer. Being cheap is a plus point.

Found out that windows automatically backs up your Desktop and Documents folder by redirecting those folders to Onedrive. Why create a seperate folder and redirect instead of just syncing from time to time

When should I develop a website myself using whatever the hot framework currently is and when should I just use something like a cms because it is too complex for only one developer to make the website

Firstly give me the skill equivalent to the best in the field. If the rules allow it all of these skills listed and if not any of these :-
1. Computer networking to the point of having the same knowledge as the best in the field. Why? I am curious about that stuff and being able to work as a network engineer if I don't get a good Dev job

2. Cyber security. Why? I enjoy it and being able to make sure my code is not easily exploitable is a cherry on top. Also having a backup job in case I don't get a good dev job

3. Being able to communicate with non dev people about developer or non developer stuff easily and being a really good leader.

4. Being a good developer in whatever language I use and instantly being able to learn new programming languages and frameworks or libraries with ultra in depth information.

What are some backstage computer science jobs(jobs most people dont know even exist but keep the show runnning and are pretty important)

Windows why do I need to explicitly tell you in a firewall rule to allow port 80 to allow someone in the same NAT as me which is set to a private network to access the web server?

Not exactly a rant but some annoyances

Whenever I copy paste code from kindle it does not space the code. Stack overflow says that kindle is using characters for space which are not present in UTF-8 which causes the issue and the find and replace option coes not work in vs code which the author is using. And if you copy from kindle whether you use the button or Ctrl + C it will add the book title and the author at the end. Who the fuck though this was a good idea.

Oh a table does not fit on the screen render whatever fits even if it is the top line of the table. This is probably not an issue and they cannot fix it and I shoild just deal with it.

The author introduces me to the language compiler and lists a command to what versions are available. I get an error which says the command is not found on windows. I dont find any solutions on google, so I go the next place and author says that he knows about it and shows a link to fix it and tells to folloe the instructions. But the link does not have any instructions and just has instructions to configure the compiler itself. The only releveant information was the path to the compiler which the author could have included there or said that was the only relevant information. The path was correct but I needed to install some stuff through Visual Studio

I just realized I can right click on a wcf service/client web.config and edit the bindings etc. in a gui. This would have made my life so much easier for (*choosing not to share for how long as it is embarrasing*).

Newbie question

Any good free resources for full stack web development. Also if a resource teaches mainly frontend but also teaches some backend it is a full stack web development resource in my eyes. I was looking at freecodecamp but it is a bit too vast for me. I am also looking at the cokplete intro to web development v2 course by Brian holt for free on frontend masters but it is 2 years old and has not been updated. Also it does not teach that much bakcend hust node and express.

Also another question is frontend masters good for web development. I did not find many threads about it. I got a discount for it which gives me a one year subscription for 195 dollars

Sorry for asking this question again but I got no replies or releated replies.

Is app academy open good for learning fullstack web development for a newbie or somewhat new to web development. There are barely any reviews on the internet about it. I did kinda ask about them in one of my previous rants but was recommended fullstackopen by @100110111
. I started fullstackopen pretty recently. App academy seems good too but it is a 1000+ hours soo I wanted to know if I am learning anything useful there.

Also thanks @100110111 fullstackopen is pretty good

Should I go for freecodecamp or app academy open or some other free resource to learn full stack web development. Freecodecamp's explanations are starting to get over my head. App academy open seems great except they teach ruby on rails before teaching MERN stack and there are only three reviews on the internet I could find

On devrant I sometimes see a good amount of posts saying angular is garbage but nearly none about react. Why is angular so hated.

I want to learn c# to build a mobile app with xamarin and a website with asp.net core. I have some programing experience and have build some meh apps. What should I use
Head First C#, 4th Edition
C# 9 and .NET 5 - Modern Cross-Platform Development - Fifth Edition
C# Fundamentals by Scott Allen on Pluralsight

C# 9 and .NET 5 - Modern Cross-Platform Development - Fifth Edition teaches what I want to learn but the Xamarin section seems a bit short. C# Fundamentals by Scott Allen on Pluralsight was recommended a lot to beginners online and I can always learn Xamarin from Microsoft Learn

Need recommendations for CMS compatible with c# and .net core. Headless CMS are fine too

Thanks

I need to run wordpress on a Windows server or Windows 10 to be used for a medium sized WooCommerce site for a reason I don't want to state. What is the best way to do this. My best options seem to be :-

Fuck people using trace rifles in momentum control. How the hell am I supposed to kill someone who kills me in two rounds and also fires at 1000 rounds per minute. I was trying to get the catalyst aka upgrade for the seasonal weapon which is pretty bad and the upgrade makes it usable but I am getting ripped apart after my first kill because someone can kill me with 2 bullets wherever he shot me.

Yes momentum control is supposed to be a gunfight mode and it comes around rarely but that does not mean a broken weapon can roam around killing anybody in sight before they even know you fired a shot at them from some lane. Shotguns do the same but you need to get close. Shotguns are still a problem but at least you can dodge or counter with a shotgun since your radar tells you someone is nearby and snipers need a headshot. These weapons can fire at your toe and you are dead. Oh the devs knew that such fast firing weapons wil be op and needed their damage and made them use the same ammo as shotguns, sniper and non heavy grenade launchers. However the game mode gives all weapons a damage buff which is enough for trace rifles to be broken. Yes you can use other primaries but what are you gonna do when a auto rifles kills you with two shots to the toe. And since they burn ammo quickly and take more rounds to kill then their counterparts like shotguns which use he same ammo as them they spawn in with 50 in the mag and anybody who is using shotguns snipers or grenade launchers give them ammo and they only need two rounds to kill. Also after I kill 50 PvP opponents I need to kill a few hundred opponents in PVE or PVP to actually apply the upgrade and who you kill does not matter.

Seriously and the second weapon I want to upgrade which is able has tracking but you need to aim down sights after hipfiring the tracking shots
which dl negligible damage so they explode or aim down sights and shoot which deals more damage but I am probably not going to have enough time before some random kills me again.

And this is just the first game. From what I heard it was supposed to be a fun game mode which focused on gunfights with your primary not the infamous laser tag show of Prometheus lens which happened a few years ago but now all trace rifles can do that. Oh and I still need to get 50 kills there for a seasonal challenge so I can get the free version of the premium currency and I can only skip one challenge and I have already skipped one challenge since it requires a dlc K don't own.

Seriously why cant some actual good game come up to challenge this. All the competition seems to be third person shooters. Also most of the guns don't feel good and lore is pretty lacking but lore is not top priority. The only competition is Warframe which is not my style, Titanfall 2 but I get insane pings from here so no multiplayer so after the story nothing to do unless I want to do airtstrafing which is useless since I can't play multiplayer. Granted Titanfall 2 is not a looter shooter but the guns feel good and the movement is too good and Halo 1 - 3 since I heard 4 and 5 are pretty bad and I have only played halo 1. I might complain about jackal snipers in halo 2 but at least they have fixed spawns.

Maybe I am overreacting since it is my first game of momentum control

Any gift recommendations. My birthday comes up in a few days and he asked what I wanted as a birthday gift(gifts are supposed to suprises but being able to choose is good still).

However I cannot ask for electronic gadgets. That knocks a lot of stuff of. The exception is that if something does not make me spend more time on the computer that is allowed. Kinda weird. For example I can ask for a printer or medical equipment like oximeters since that wont make me spend more time on the computer. Both of these examples were given by my father. I could ask for a new printer however we still have a printer but it is currently in the shop since it is not being used and the shops printer broke and is hell to replace since they need chips to verify toners and you need to get those chips separately from what my father told me and the shops printer should be repaired in a few months since lockdown was lifted a few days ago and I won't need to print something since everything is online and they don't need to show student projects yet.

Thia knocks a lot of hardware off since by definition if I am using hardware I still need to code it to do something which is more time on computer which is not allowed. So no fiddling with aurdino or rasberry pie or whatever is the most used hardware kit.

I can buy some course or a book to learn something but I already have problems with consistently learning c# with a good book which will lose value in November and that most topics I would like to learn like computer networking or some new language are practical which is more time on computer which is not allowed.

So the only thing I can buy are some books to enjoy reading for fun or some school books like a science digest book like Together with or the ultra popular maths reference book RD Sharma

So what things should I ask which comply with the rules my father has laid or just skip this thing

Yo anyone who uses hikvision, do they still use npapi requiring use of older browsers or a plugin or other software like iVMS

Should I write my app as a pwa or in electron. The app needs to be on mobile devices too but I wont mind rewriting the app for another platform since the app is pretty small. It only needs notifications, network access and basic read and write access to write some pretty small configs. Most of the code will be for the ui anyways
