In a user-interface design meeting over a regulatory compliance implementation:
User: “We’ll need to input a city.”
Dev: “Should we validate that city against the state, zip code, and country?”
User: “You are going to make me enter all that data? Ugh…then make it a drop-down. I select the city and the state, zip code auto-fill. I don’t want to make a mistake typing any of that data in.”
Me: “I don’t think a drop-down of every city in the US is feasible.”
Manage: “Why? There cannot be that many. Drop-down is fine. What about the button? We have a few icons to choose from…”
Me: “Uh..yea…there are thousands of cities in the US. Way too much data to for anyone to realistically scroll through”
Dev: “They won’t have to scroll, I’ll filter the list when they start typing.”
Me: “That’s not really the issue and if they are typing the city anyway, just let them type it in.”
User: “What if I mistype Ch1cago? We could inadvertently be out of compliance. The system should never open the company up for federal lawsuits”
Me: “If we’re hiring individuals responsible for legal compliance who can’t spell Chicago, we should be sued by the federal government. We should validate the data the best we can, but it is ultimately your department’s responsibility for data accuracy.”
Manager: “Now now…it’s all our responsibility. What is wrong with a few thousand item drop-down?”
Me: “Um, memory, network bandwidth, database storage, who maintains this list of cities? A lot of time and resources could be saved by simply paying attention.”
Manager: “Memory? Well, memory is cheap. If the workstation needs more memory, we’ll add more”
Dev: “Creating a drop-down is easy and selecting thousands of rows from the database should be fast enough. If the selection is slow, I’ll put it in a thread.”
DBA: “Table won’t be that big and won’t take up much disk space. We’ll need to setup stored procedures, and data import jobs from somewhere to maintain the data. New cities, name changes, ect. ”
Manager: “And if the network starts becoming too slow, we’ll have the Networking dept. open up the valves.”
Me: “Am I the only one seeing all the moving parts we’re introducing just to keep someone from misspelling ‘Chicago’? I’ll admit I’m wrong or maybe I’m not looking at the problem correctly. The point of redesigning the compliance system is to make it simpler, not more complex.”
Manager: “I’m missing the point to why we’re still talking about this. Decision has been made. Drop-down of all cities in the US. Moving on to the button’s icon ..”
Me: “Where is the list of cities going to come from?”
<few seconds of silence>
Dev: “Post office I guess.”
Me: “You guess?…OK…Who is going to manage this list of cities? The manager responsible for regulations?”
User: “Thousands of cities? Oh no …no one is our area has time for that. The system should do it”
Me: “OK, the system. That falls on the DBA. Are you going to be responsible for keeping the data accurate? What is going to audit the cities to make sure the names are properly named and associated with the correct state?”
DBA: “Uh..I don’t know…um…I can set up a job to run every night”
Me: “A job to do what? Validate the data against what?”
Manager: “Do you have a point? No one said it would be easy and all of those details can be answered later.”
Me: “Almost done, and this should be easy. How many cities do we currently have to maintain compliance?”
User: “Maybe 4 or 5. Not many. Regulations are mostly on a state level.”
Me: “When was the last time we created a new city compliance?”
User: “Maybe, 8 years ago. It was before I started.”
Me: “So we’re creating all this complexity for data that, realistically, probably won’t ever change?”
User: “Oh crap, you’re right. What the hell was I thinking…Scratch the drop-down idea. I doubt we’re have a new city regulation anytime soon and how hard is it to type in a city?”
Manager: “OK, are we done wasting everyone’s time on this? No drop-down of cities...next …Let’s get back to the button’s icon …”

*Got a request for installing and configuring an online shop for a client*
Me: Do you have a web space already?
Client: No, I don't want to pay for it. (FYI: They only cost about 20€ a year)
Me: Okay, but free hosters are often slow and unprofessional. I really do not recommend using free hosting services.
Client: Doesn't matter, do it.
Me: *Working on the shop for several weeks, finally goes online*
One week later, client contacts me saying shop is offline. I realize the free hoster he used shut down their services (bankruptcy), resulting in the loss of about 90% of the work that I had done (no proper backups due to complexity)
Client: How can that even happen? You'll redo the shop, right?

Back in the day, I joined a little agency in Cape Town, small team small office with big projects, projects they weren’t really supposed to take on but hey when the owner of a tech business is not a tech person they do weird things.
A month had passed and it was all good, then came a project from Europe, Poland to be specific. The manager introduced me to the project, it was a big brand - a segment of Lego, built on Umbraco (they should change the name to slowbraco or uhmmm..braco somewhere there) the manager was like so this one is gonna be quite a challenge and I remember you said you are keen on that, I was like hell yeah bring it on (genuinely I got excited) now the challenge was not even about complexity of the problem or code or algorithms etc you get my point… the challenge was that the fucking site was in polish - face palm 1 - so I am like okay code is code, its just content, and I already speak/familiar with 13 human languages so I can’t fail here ill get around it somehow. So I spin up IIS, do the things and boom dev environment is ready for some kick ass McCoding. I start to run through the project to dig into the previous dev’s soul. I could not relate, I could not understand. I could not read, I could not, I could not. - face palm 2 - This dude straight up coded this project in polish variable names in polish, class names in polish, comments in freaking polish. Look, I have no beef with the initial guy, its his language so why not right? sure. But not hey this is my life and now I should learn polish, so screw it, new tab - google translate, new notes, I create a dictionary of variables and class etc 3 days go by and I am fucking polish bro. Come at me. I get to read the previous devs soul through his comments, what a cool dude, his code wasn’t shit either - huge relief. So I rock on and make the required changes and further functionality. The project manager is like really, you did it? I am like yeah dude, there it is. Then I realise I wasn’t the first on this, this dude done tried others and it didn’t go down well, they refused. - face palm 3 -
Anyway, now I am a rock star in the office, and to project managers this win means okay throw him in the deep - they move me to huge project that is already late of course and apparently since I am able to use google translate, I can now defeat time, let the travelling begin. - face palm 4 - I start on the project and they love me on it as they can see major progress however poland was knocking on the door again, they need a whole chunk of work done. I can’t leave the bigger project, so it was decided that the new guy on Monday will start his polish lessons - he has no idea, probably excited to start a new job, meanwhile a shit storm is being prepared for him.
Monday comes, hello x - meet the team, team meets x
Manager - please join our meeting.
I join the meeting, the manager tells me to assist the new dev to get set up.
Me: Sure, did you tell him about he site?
Manager: Yes, I told him you knocked it out the park and now we just need to keep going
Me: in my head (hmm… that’s not what I was asking but cool I guess he will see soon enough -internal face palm 5 - ) New dev is setup, he looks at the project, I am ask him if he is good after like an hour he is like yeah all good. But his face is pink so I figured, no brother man is not okay. But I let him be and give him space.
Lunch time comes, he heads out for lunch. 1hr 15mins later, project manager is like, is the new dude still at lunch.
We are all like yeah probably. 2hrs pass 3hrs pass Now we are like okay maybe something happened to him, hit by a car? Emergency? Something… So I am legit worried now, I ask the manager to maybe give him a ring. Manager tries to call. NOTHING, no response. nada.
Next day, 8am, 9am, 10am no sign of the dude. I go to the manager, ask him what’s up. Manager: he is okay. However he said he is not coming back.7 -
In my previous rant about IPv6 (https://devrant.com/rants/2184688 if you're interested) I got a lot of very valuable insights in the comments and I figured that I might as well summarize what I've learned from them.
So, there's 128 bits of IP space to go around in IPv6, where 64 bits are assigned to the internet, and 64 bits to the private network of end users. Private as in, behind a router of some kind, equivalent to the bogon address spaces in IPv4. Which is nice, it ensures that everyone has the same address space to play with.. but it should've been (in my opinion) differently assigned. The internet is orders of magnitude larger than private networks. Most SOHO networks only have a handful of devices in them that need addressing. The internet on the other hand has, well, billions of devices in it. As mentioned before I doubt that this total number will be more than a multiple of the total world population. Not many people or companies use more than a few public IP addresses (again, what's inside the SOHO networks is separate from that). Consider this the equivalent of the amount of public IP's you currently control. In my case that would be 4, one for my home network and 3 for the internet-facing servers I own.
There's various ways in which overall network complexity is reduced in IPv6. This includes IPSec which is now part of the protocol suite and thus no longer an extension. Standardizing this is a good thing, and honestly I'm surprised that this wasn't the case before.
Many people seem to oppose the way IPv6 is presented, hexadecimal is not something many people use every day. Personally I've grown quite fond of the decimal representation of IPv4. Then again, there is a binary conversion involved in classless IPv4. Hexadecimal makes this conversion easier.
There seems to be opposition to memorizing IPv6 addresses, for which DNS can be used. I agree, I use this for my IPv4 network already. Makes life easier when you can just address devices by a domain name. For any developers out there with no experience with administration that think that this is bullshit - imagine having to remember the IP address of Facebook, Google, Stack Overflow and every other website you visit. Add to the list however many devices you want to be present in the imaginary network. For me right now that's between 20 and 30 hosts, and gradually increasing. Scalability can be a bitch.
Any other things.. Oh yeah. The average amount of devices in a SOHO network is not quite 1 anymore - there are currently about half a dozen devices in a home network that need to be addressed. This number increases as more devices become smart devices. That said of course, it's nowhere close to needing 64 bits and will likely never need it. Again, for any devs that think that this is bullshit - prove me wrong. I happen to know in one particular instance that they have centralized all their resources into a single PC. This seems to be common with developers and I think it's normal. But it also reduces the chances to see what networks with many devices in it are like. Again, scalability can be a bitch.
Thanks a lot everyone for your comments on the matter, I've learned a lot and really appreciate it. Do check out the previous rant and particularly the comments on it if you're interested. See ya!25 -

Fuck you. Stop asking time complexity or space complexity of functional code. No one fucking knows.8 -
fuck time zones and time changes, why the fuck we don’t have one time on the planet and one date that is just day.
No month, no years - all the complexity would be gone, day wouldn’t have 24 hours but it would be something more precise, there won’t be a second
time that earth goes around sun is
365,25964 days
31558432896 milliseconds
we should start count time differently so it’s not relative in space time continuum, what should be relative is the mass32 -
I definitely made a channel in the dev Slack I'm in for algo practice with the description bigOHNOtation.3

Reminded again why every professional developer should at least read and understand basic algorithms...
Colleague: I don't understand why this agregation query is so slow, the counting is on the DB.
This function used to work fine... Now it sometimes hangs.
Me thinking: why does everyone assume db has unlimited resources and computing power so everything should be quick (no time or space complexity)...
Maybe if everyone understood this stuff our code base wouldn't be so shitty from the start...8 -
Not dev but, enough for the story. Had an assignment to create a hashtable for my DS course. Asked a friend how he managed resizing and the load factor
Friend= tablesize*50
Me= what...
Friend= space complexity what... -
Do dev or engineer needs to know how the program works?. I mean that should they know about time and space complexity?
Till now my answer is yes, they should know. But i have met more than triple Dev's with absolutely no knowledge of complexity and they all are behind code quality.6 -
If we can transform the search space or properties of a product into a graph problem
we could possibly use Kirchhoff's theorem to reveal products which are 'low complexity'
in particular search spaces, yeah?
Now according to
https://en.wikipedia.org/wiki/...
"n Cycle Space, A family of sets closed under the symmetric difference operation can be described algebraically as a vector space over the two-element finite field Z 2 {\displaystyle \mathbb {Z} _{2}} \mathbb{Z } _{2}.[4] This field has two elements, 0 and 1, and its addition and multiplication operations can be described as the familiar addition and multiplication of integers, taken modulo 2"
Wouldn't this relate to pollards algorithm, because it involves looking for factors of coprimes modulo N or am I mistaken?
Now, according to wikipedia, "in a group, the additive identity is the identity element of the group, is often denoted 0, and is unique."
If we make the multiplicative identity of our ring or field a tuple of the ratio of a/b for some product p, or a (and a/w, where w is the square root of p), or any other set such that n*m allows us to derive a or b, we could reduce the additive identity to the multiplicative identity, making the ring trivial. Solving for p would then mean finding a function from R to R, mapping every number to 0, i.e. finding the additive identity.
Now in a system with a multiplication operation the distributes over addition, the "additive
identity annihilates ring elements", so naturally, the function that maps to 0, gives us
our additive identity, we need only find the subset, no?
Forgive me if I'm wrong, but shouldn't this be convertible to a graph search?
I'm WAY out of my depth here so if anyone is familiar and can enlighten me I'd be grateful.
It's all unknown unknowns to me. -
Today I'm starting interviewcamp.io. I graduated from a 4-year university in California with a degree in computer engineering and have almost 3 years of work experience, but my god I am terrible at algorithms.
Big O (time and space complexity), recursion, Binary Search Trees, reversing a fucking linked list, etc. I need the boost and I hope the $250 a year for the material will help me get at least a $5k increase in salary when jumping to another company after the whole pandemic (or get a raise at my current job).
If anyone has any experience with them let me know. So far I'm 2 hours in and it is nice so far.3 -
