Arghhh, rant time :|

So yesterday I completed a database migration of 167,000 products from an old ecommerce system to a new one. Everything was brought over, orders, customer addresses, everything, really chuffed :)

The only thing the client picked up on was the lack of his spammy "meta keywords" data that I intentionally did not import. I mean the tag isn't used and a list of 40 comma separated random words you'd like to rank for isn;t going to help the sites SEO on bit.

Anyway, the client is now moaning a lot and insisting I add them in. Even after I explained that the meta keywords is gone for good reasons he insists on keeping the data.

Soooo, pointless :|

(note the tags for the sake of satire :) )

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 ✌🏼

iPhones are ridiculously picky when it comes to finding a mate- um charger. And knowing why doesn't really make it any easier to understand why. If anything it baffles me more.

So, let's start with appliances that are not phones. Think Bluetooth headsets, keyboards, earbuds, whatever. Those are simple devices. They see 5V on the VCC line and 0V on ground, and they will charge at whatever current they are meant to. Usually it will not exceed 200mA, and the USB 2.0 spec allows for up to 500mA from any USB outlet. So that's perfectly reasonable to be done without any fuss whatsoever.

Phones on the other hand are smarter.. some might say too smart for their own good. In this case I will only cover Android phones, because while they are smarter than they perhaps should be, they are still reasonable.

So if you connect an Android phone to the same 5V VCC and 0V ground, while leaving the data lines floating, the phone will charge at 500mA. This is exactly to be within USB 2.0 spec, as mentioned earlier. Without the data lines, the phone has no way to tell whether it *can* pull more, without *actually* trying to pull more (potentially frying a charger that's not rated for it). Now in an Android phone you can tell it to pull more, in a fairly straightforward way. You just short the data lines together, and the phone will recognize this as a simple charger that it can pull 1A from. Note that shorting data lines is not a bad thing, we do it all the time. It is just another term for making a connection between 2 points. Android does this right. Also note that shorted data lines cannot be used to send data. They are inherently pulled to the same voltage level, probably 0V but not sure.

And then the iPhones come in, Thinking Different. The iPhones require you to pull the data lines to some very specific voltage levels. And of course it's terribly documented because iSheep just trying to use their Apple original white nugget charger overseas and shit like that. I do not know which voltage levels they are (please let me know!), but it is certainly not a regular short. Now you connect the iPhone to, say, a laptop or something to charge. An Android phone would just charge while keeping data transmission disabled (because they can be left floating or shorted). This is for security reasons mostly, preventing e.g. a malicious computer from messing with it. An iPhone needs to be unlocked to just charge the damn thing. I'm fairly sure that that's because the data lines need to be pulled up, which could in theory enable a malicious computer to still get some information in or out of it. USB data transmission works at at least 200mV difference between the data lines. It could be more than that. So you need to unlock it.

Apple, how about you just short your goddamn data lines too like everyone else? And while you're at it, get rid of this Lightning connector. I get it, micro USB was too hard for your users. I guess they are blind pigs after all. But USB-C solved all of that and more. The only difference I can think of is that the Lightning connector can be a single board with pads on either side on the connector, while in USB-C that could be at the socket end (socket being less common to be replaced). And at the end of the day, that really doesn't matter with all the other things that will break first.

Think Different. Think Retarded. Such tiny batteries and you can't even fucking charge them properly.

If anyone has been keeping up with my data warehouse from hell stories, we're reaching the climax. Today I reached my breaking point and wrote a strongly worder email about the situation. I detailed 3 separate cases of violated referential integrity (this warehouse has no constraints) and a field pulling from THE WRONG FLIPPING TABLE. Each instance was detailed with the lying ER diagram, highlighted the violating key pairs, the dangers they posed, and how to fix it. Note that this is a financial document; a financial document with nondeterministic behavior because the previous contractors' laziness. I feel like the flipping harbinger of doom with a cardboard sign saying "the end is near" and keep having to self-validate that if I was to change anything about this code, **financial numbers would change**, names would swap, description codes would change, and because they're edge cases in a giant dataset, they'll be hard to find. My email included SQL queries returning values where integrity is violated 15+ times. There's legacy data just shoved in ignoring all constraints. There are misspellings where a new one was made instead of updating, leaving the pk the same.

Now I'd just put sorting and other algos, but the data is processed by a crystal report. It has no debugger. No analysis tools. 11 subreports. The thing takes an hour to run and 77k queries to the oracle backend. It's one of the most disgusting infrastructures I've ever seen. There's no other solution to this but to either move to a general programming language or get the contractor to fix the data warehouse. I feel like I've gotten nowhere trying to debug this for 2 months. Now that I've reached what's probably the root issue, the office beaucracy is resisting the idea of throwing out the fire hazard and keeping the good parts. The upper management wants to just install sprinklers, and I'm losing it.

I'm starting to be really, idk, crazy, but I just can't find anything similar to OneNote, but with SYNC option, for Android and Linux. What do you guys recommend. Already tried Evernote but it's two-devices only limit in free version, nah.

Day 3 of devWholesome...

Go tell a loved one you love them! Give them a hug, call them, text them, etc. Its always great to give love to the ones closest to you. Try and spend some time with them! Again make sure you are eating your meals and drinking your water (maybe with your family?) as well as taking care of yourself and keeping yourself from stress. And as always, make the most out of your day!

Note: If you want to see any devWholesome posts, you can look at all of them by looking up the devwholesome tag!

This is a place for ranting, right? It's "Dev"-"Rant", right?
So, why so much hate when people do actually rant?
Kinda defeats the purpose, doesn't it? Or maybe the name is just misleading...
Or maybe y'all just gate-keeping ranting - which is... ya, okay - you do you, you preppy tosser.

Anyway, on that note:
I fucking hate web-development.
I fucking hate CSS.

CSS isn't a tool, it's a curse.
It's like a soft black magic system:
This specific behavior can sometimes be created by combining these specific elements, but will fall apart if you're a gemini - unless you wore a colorful hat at your fifth birthday party. If you didn't have a party, it'll produce some random behavior of the deer-god's choosing.

What would be the best tips for keeping code clean?

I recently noticed how "unclean" my code is, I try to organize it as much as possible but through that I manage to make the code very messy :/
What are your best tips, advise, tricks... lalala?

Note:
This problem mainly applies to long projects and games :P

Sooo I think my VPS slowly dying. Disk r/w performance has gone to shit - we're talking ~10MB/s write speed on a fucking SSD.
Is there any way to bring it back to life? Or should I just give up?

Note: I've been keeping this VPS alive for years because it only costs me 1 eur/month, and they don't have this offer anymore - it costs triple now, so I reeeeally don't want to lose that price.
Also, I'm using it as a DNS server (among other things), and I really like the IP address, so I don't really wanna lose that either...

What do?

studies in memory indicate that a person recalls information better when exposed to the same biological, and emotional state they were in when the information being recalled, be it semantic or episodic.

other aspects include many other cues.
what conversations people were having
the same people being there
similar sensory inoyt
and being in the original place where the memory was formed.

but some information is so jarring that the brain when kept in a consistently aggravated state of emotional unease and vigilance can be repressed along with from what i note, connected semantic information if say the information recalled was related to a nearly alien state of considerable mind and perception altering terror and unhappiness.

we often forget bad things because its the only way we heal.

the most evil people in the world found a way to recreate this trauma so they could add.
parallel memories. whole tracks of human experience existing apart from each other, just in the hopes of keeping that person quiet.

ironically for a person who is nice, witnessing these types of people responsible for these things get murdered or brutally deformed, also tends to be buried away with the same repressed memories.

Hi devRant!
I'm here asking for your advice!
I'm a MSc student in my mid 20s, I took a gap year to work as an IT consultant and I'm planning on going back to studying, keeping at the same time a part-time job.

I already have some experience as a data engineer, developer and sys admin. I'm also mastering in applied statistics and data science and have a BSc in physics. I'm planning to relocate around Europe. All I want is a salary I can live with and a good work/study/life balance (perhaps work 24-30hrs a week?).

So far I've checked out a few IT jobs website and I've found some suitable positions. Problem is most of them are fulltime.

Where would you search for such a job? Is there any website/portal I should prefer? How would you proceed?
Should I prefer any place in particular (i.e. Northen countries)?

Thank you in advance <3

Note: I know it's a very broad question, that's because I'm open to any piece of advice you are willing to give me
