A "support" guy my boss got in. I had told my boss numerous times, "Get rid of this guy, he's only wasting our time and money. And he's going to end up doing something where we will end up having to put out the fires."
Sure as a pair of nuts on a squirrel, this crazy bastard goes and DELETES a client's database. Yes folks, in fucking production. A live database. The heart of the business' transactions are... *poof*... GONE!!!
No backups for the day! No synchronisation beforehand! No nothing... just GONE!!! Fucking flat-lining!
Well, when I realised what he has done, I had to remove myself from the room before shit got outta hand!
I told the boss man that is the last straw and he needs to go...
The long and short of it...
- The client had luckily only lost about half a days data.
- I'm no longer at the company.
- This dumb fuck still is.

Anyone who creates a Facebook Libra account and puts money in it and uses it to buy stuff/for transactions should have their fucking voting rights removed and be submitted to a mental health institution.
Just my personal opinion.26 -
The network starts slowing down, transactions start to fail across the 450+ stores, the website starts to spit 500 errors what is going on?
Queue a frantic running around the office working out what was going wrong... Calls from all 3 data centres, nothing is going in or out of the network.
Notice the network admin come back to his desk, his eyebrows raise and he looks left and right before unplugging his laptop ethernet from one of the server access points
The network rushes back to life, everything is fine.
That particular network mapping tool is now banned for use on production.10 -
I very very rarely drink, but when I do I party hard.
I negotiated an entire piece of complex web architecture (really huge, works at 50k transactions per second), with my boss who's a lead architect, from a bar (he thought I was home), while moderately drunk.
It got me a lotta praise and till date it's one of the best pieces of software I've ever written. It saved the company 500+ hours or something #humblebrag.
To this day I have no recollection of what I said (huge hangover after) or how I managed to come up with that shit. I don't think I'd have been able to do it sober. The sheer size of the problem would've made me go "yea it works, I'm not touching that. Nope."
DAE notice any increase in pattern recognition in their code while drunk?1 -
A major bank had a bug in their system that triggered multiple postings of transactions in all of their clients' accounts. When they found out the root cause, they just had to mention that the programmer was a female. Like that was any bearing to the problem. It's not like they have like a whole fucking team of QA testers that should have checked that shit before it went to production.14

Short version:
Dear devRantdairy,
today I was stupid.
The End.
Full version:
I am working on some messaging system, trying to use less as possible overhead sending data. Therefore there of course are asynchronous calls and some templating. But that's just the setting of the rant: I designed an architecture to save conversations in a database. Working with transactions in pdo I wrote a query wich in my eyes should have worked well. But the result just didn't appear in the table. So I started debugging data. Recreated the table. Rewrote the query. Went to bed. Woke up. Further tryed to make this work. And in the end I realized I just forgot to commit the transaction.
How dumb can you be? There's way too much time gone for that mistake. Is there a hole? I want do dig myself.7 -
WHY can I only make digital payments on weekdays, 7:00-16:00?? Its not like there's a human authorizing all transactions. And computers don't sleep!!4
-
Well on my first job we had to integrate payment gateways in client apps for online payment. On my second week in office I published an app on the play store with payment gateway credentials for a different client cause they were there as default values. So the money for one client would go to the other. Nobody noticed it for two weeks and when they did, I thought I had just lost my job and also I would now have to pay all the losses out of my pocket but fortunately I didn't have to cause no transactions had yet been made. After that I always checked my integrations atleast five times before publishing. The incident scared the shit out of me but taught me the value of developer responsibility.2

I feel I am getting paid for getting trolled (you read that right) - I have had now two completely seperate clients, a month apart - paying me hundreds of dollars for "testing".
I have explained both of them atleast for a total of 8 hours why there's "sandbox" accounts and that the "virtual money" is the same as "real money", so later when you go live, it will be the exact same, just without the need of actually testing with actual money.
I even as a last suggestion asked to atleast be developing with $0.01 transactions (to literally not run out of additional money, because of the different packages), but they wanted it to be as "real" as possible. -
Accountant: Can we just get one big Excel file with all the transactions instead of separate reports that are filled out specifically for each dorm?
Me: Hell yes you can.3 -
User: I need you to extract all the invoice data for us.
Me: What invoice data in particular, what are filters you require. This is a massive database with millions of transactions.
User: JUST EXTRACT THE TABLE!
Me: Right.....(this is a database with 3000+ tables and hundreds of joins)7 -
Massive payment gateway (not gonna say names) with more then 10k transactions / hour telling md5 is one of most secure encryptions they have. Only to made worse by the fact that they send the key and hashed key in the same request.
I am advising all our clients to change payment gateway asap if they use this one.1 -
kinda coding i guess, company specialising in making statistics for other companies, analytic stuff or such, wanted stack: php, mysql
Interviewer: so here is our tech guy, who will be your boss if... so he would like to ask a few questions
techGuy: how would you ask for all the rows in a table? * looks at me *
Interviewer: * looks at me too *
me (learning inner, outer, left, right joins and transactions yesterday): * am i a joke to you? *
also me: * they must be making fun of me or something * well the query should be SELECT * FROM tableName; but one should really not use that, as * in theory really slows things down, because it loads unnecessary meta data bla bla
they: * look at each other * You're really good young man! Yes of course we know that, haha!
Interviewer: You said you just finished Uni, you doesn't seem like a junior to me! good job!
techGuy: so how would you LIMIT your results to 100 rows?
me: sigh * looks at door without turning head, so they wont notice *4 -
Dogecoin hit USD $0.40 recently, which means it's time for the Crypto Rant.
TL;DR: Dogecoin is shit and is logically guaranteed to eventually fall unless it is fundamentally changed.
===========================
If you know how Crypto works under the hood, you can skip to the next section. If you don't, here's the general xyz-coin formula:
Money is sent via transactions, which are validated by *anybody*.
Since transactions are validated by anybody, the system needs to make sure you're not fucking it up on purpose.
The current idea (that most coins use today) is called proof-of-work. In short, you're given an extremely difficult task, and the general idea is you wouldn't be willing to do that work if you were just going to fuck up the system.
For validating these transactions, you are rewarded twofold:
1) You are given a fixed-size prize of the currency from the system itself. This is how new currency is introduced, or "minted" if you prefer.
2) You are given variable-size and user-determined prize called "transaction fees", but it could be more accurately called a "bribe" since it's sole purpose is to entice miners to add YOUR transaction to their block.
This system of validation and reward is called mining.
===========================
This smaller section compares the design o f BTC to Dogecoin - which will lead to my final argument
In BTC, the time between blocks (chunks of data which record transactions and are added to the chain, hence blockchain) is ten minutes. Every ten minutes, BTC transactions are validated and new Bitcoins are born.
In Dogecoin, the time between blocks is only one minute. In Theory, this means that mining Dogecoin is about ten times easier, because the system expects you to be able to solve the proof of work in an average of one minute.
The huge difference between BTC and Doge is the block reward (Fixed amount; new coins minted). The block reward for BTC is somewhat complicated compared to Doge: It started as 50 BTC per block and every 4 years it is halved ("the great halving"). Right now it's 6.25 BTC per block. Soon, the block reward will be almost nothing until BTC hits it's max of 21 million bitcoins "minted".
Dogecoin reward is 10,000 coins per block. And it will be that way for the end of time - no maximum, no great halving. And remember, for every 1 BTC block mined, 10 Doge blocks are mined.
===========================
Bitcoin and Dogecoin are now the two most popular coins in pop culture. What makes me angry is the widespread misunderstanding of the differences between the two. It is likely that most investors buy Dogecoin thinking they're getting in "early" because it's so cheap. They think it's cheap because it isn't as popular as Bitcoin yet. They're wrong. It's cheap because of what's outlined in section two of this rant.
Dogecoin is actually not very far off Bitcoin. Do the math: there's a bit over 100 billion Dogecoin in circulation (130b). There's about 20 million BTC. Calculate their total CURRENT values:
130b * $0.40 = 52b
20m * $60k = 1.2t
...and Doge is rising much, much faster than BTC because of the aforementioned lack of understanding.
The most common thing I hear about Doge is that "nobody expects it to reach Bitcoin levels" (referring to being worth 60k a fucking coin). They don't realize that if Doge gets to be worth just $10 a coin, it will not just reach Bitcoin levels but overtake Bitcoin in value ($1.3T).
===========================
It's worth highlighting that Dogecoin is literally designed to fail. Since it lacks a cap on new coins being introduced, it's just simple math that no matter how much Doge rises, it will eventually be worthless. And it won't take centuries, remember that 100k new Doge are mined EVERY TEN MINUTES. 1,440 minutes in a day * 10K per minute is 14.4 million new coins per day. That's damn near every Bitcoin to ever exist mined every day in Dogecoin

So I started getting email notifications telling me about transactions made using my credit card. But I DON'T have a credit card in the first place.
Instead of trying to call customer care and pressing an endless array of buttons, I drive to the bank. I tell them the situation and they check every database they have but they couldn't find any trace of a card connected to my account. Turns out their database somehow had cross-links in their database.
How does the one of the biggest banks in the country possibly have such an issue. Worst part is that it's been a day and they still haven't fixed it -_-7 -
Am I the only one who doesn't understand apple card? Like really, it's just the worst pitch ever!
"Apple card. Made by apple. Not a bank" that's a REAL ad I saw today. Why would you trust APPLE more than an FDIC insured bank with decades or (in some select cases) CENTURIES of experience in finance?
"No more card numbers and CVV"
Cool. I get it. Card numbers get leaked and stolen. But that's why banks insure cards and reverse fradulant transactions. How an I'm supposed to use it on Amazon?! I'm sure they have an answer. Like maybe one time use generated cards. But they haven't advertised it yet, and that's a problem!
Why do they think people want this!? And even more so, because I've seen some people are excited: WHY DO PEOPLE WANT THIS?! why is apple trying to make everything?!15 -
Boss: So what are your biggest achievements for this year?
Me: mmm, probably not killing myself
Boss: .....
Me: I meant I reduced the number of fraudulent transactions in our service by adding machine learning to flag suspicious transaction
Boss: Yeah, you should've start with that
Me: .....3 -
Spec'ing out a data analysis tool for several billion transactions and I got this when sending the final spec to the client.
Client: "I don't see why it takes so long, I downloaded this template from theme forest and edited it in dreamweaver, it only took 3 hours"2 -
There are many, but in in particular,
EA!!!
There could many reasons, overpriced games, micro-transactions...
All of them can be described as "just business"
But one stands out and makes it personal, the reason I wouldn't just shoot the game-designer but stab him and watch him drown in his own blood.
MASSEFFECT ANDROMEDA!!!!!
It felt like they took all the mistakes the third game made, and continued to add some more.
1. The PS4-Version had so many performance-issues, it was pretty much unplayable
2. Instead of a good story, interesting characters and fun battles, we got an open-world.
3. Facial animations and voice-acting from hell.10 -
On the nth day of Christmas, my true love gave to me:
1 misconfigured autoscaling group
200 unnecessary servers
29 urgent emails
3 support teams that would have fixed the problem in an hour of anybody had bothered going to them first
Ugh. Idiots. Somehow the whole issue was caused by a single full hard disk, which caused database transactions to fail, which caused the group to scale out and spin up new instances, which didn't actually fix the problem so it kept scaling until it hit the limit and then continuously failed to create new instances for several hours straight, generating loads of notification emails and generally causing problems for everyone involved. -
Noticed a rant on here about transactions not redirecting the user back to the previously visited page, on certain sites. Just implemented the functionality to my shitty little project and I currently feel better than the big players.1
-
i nearly had a panic attack when 3 tables contaning transactions shows empty,. then i reconnected dbeaver and it turns out it was fine,. damn my shitty internet!

Wow so much hate for WordPress. Le me to the rescue 💀
Yes WP is bloated and crappy and full of security issues etc etc. Agreed. That doesn't mean it is useless though.
It is alright to use for someone who is not really good with web, someone who just needs a blog, someone who just needs a home page, about page and contact form with a possibility of updating photo and text once or two times a month.
It is not suitable for e-commerce nor lots of transactions/forms involving websites.
As long as you know what kind of horse/vehicle you are on, you won't end up in the dirt.4 -
Today I had plans to refresh my knowledge about transactions' internals in dbms and in general.
Then the rainy weather hit the town. The whole sleepy day wasted on Netflix.
Well.. I guess it was time for a break :) haven't had one in weeks3 -
Someone stole my CC number and paid a bunch of spam ads on FB with it tonight. When I woke up and blocked it, there's been already 400€ worth of transactions done with it :(
But the real rant is that it took 3 fucking hours before I managed to get in contact with someone at FB who could actually help me. Fuck those AI chat bots & "Tenk yu kom agan" support guys!9 -
Really glad the privacy community can make some impact. I still don't understand why venmo has to has any public transaction feed and I don't think they have public off by default still, but at least they are explaining things to users instead of being sneaky with their dumb social-network-ish-thingy that made ALL OF YOUR FINANCIAL TRANSACTIONS PUBLIC!!????
I don't understand why they hid this whole public feed thing. I'm pretty privacy focused and I didn't even know that my transactions where public untill I saw https://publicbydefault.fyi/.

Just spent 8 hours debugging an issue that had been sitting in my issue queue for a week. WooCommerce was claiming transactions were failing, but going through in the background anyway.
Can’t share any more specifics here, but the gist of it is that the server the code was developed on was set to PHP version 7.1, while the server the dev site was on was set to version 5.6 (which I didn’t even think was still installed, never mind the default...).
So yeah, fun times over a trivial fix.1 -
So today I accidentally updated more than 3000 records in a table and wasn’t using transactions so I couldn’t Rollback, LOL had the whole team freak out this Monday morning and we had to pull a backup6
-
I worked for this Chinese company, one of their systems that was supposedly handling millions of US$ in transactions per day had an API that returned HTML tables...
I stop you right there commenter, there was no format=json parameter.
Another of their API I gave up on:
Status = 200
Content = "error"3 -
Customer: the user summary report does not show all the transaction data I want to see
Me: there is a report called "transaction log report" that will show all the transactions
Customer: is that the user summary report? -
"Our supplier asks that you double the number of php child processes for this fpm pool"
"Are you aware, that that would lead to about 100% of memory overcommit, taken the current limit of 128MB/child, and that if a lot of them started at once, the system would probably go for OOM-Kill, which would most probably kill your database, that still runs on 100% MyISAM tables that do not support transactions, and you'd have to kiss your data integrity goodbye, right?"
"Uh... Nevermind then"
I get that some people are not IT-versed, but really... Hire someone who knows what they are doing and doesn't live 20 years in the past, god damn it! -
I applied for two technical talks in a popular conference summit, the two talks were turned down and the reason was that they are much more technical talks than mine. I switched to watch the live stream today and all i see is a bunch of stupid talks (they decided to pick a talk on git aliases over working with change streams and multi document transactions in mongodb). A friend of mine just told me, your talk won't be accepted if you don't know any of the organizers3
-
Thanks MongoDB for introducing transactions (ACID) in 4.0 version ... This is really going to help a lot.1

Me: *asks for sample data for all tables to test database transactions*
Team member: *gives over 45000 records only for city*

That awkward moment when you're trying to find patterns to pin point trade ahead transactions on stock market and you realized that you were hired as Android developer.

Friday 5:13pm
- Critical report: "We're allowing users to withdraw more money then they actually have in their accounts"
5:16pm
- "False alarm. There is pagination on the transactions interface". Have a nice weekend everyone!1 -
My first simplistic wallet to create raw Bitcoin transactions. The best part was that the transaction was mined succesfully and is now part of history.

Last night I looked at an Android app.
Going to put it bluntly, I don't like java much.
But Android takes it to a whole new level.
I was talking to our (SlimRoms) framework dev about how the database transactions used to take 400ms, and it was cut down to 10ms by, changing to xml with some kind of a reflector (so xml would be saved in the background).
This is atrocious. As a web developer, I live in a world where you can do thousands of transactions in that time (albeit on faster hardware).
So how is it that all of the abstractions in Android add up to a single read/insertion in Android (and I'm talking about an app written by Google) takes 400ms?
Every time I go in that channel to talk to them, I find something screwed up. Gah.4 -
Why yes we have these nine types of transactions mocked. See? The factories make CSV data just like we get in those gigantic CSV files every day that are like ultra-important or whatever.
Wait, you want to actually use the data? to create records? Like build a record like we do in the code? Nonononono that won’t work! Why? Why!? You want us to actually MOCK the data, like make it look real AND MAKE IT PASS VALIDATION? Are you CRAZY!? THERES LIKE THIRTY COLUMNS THERE! No way. No no no way. If you want to do that, you’re on your own. But make sure you don’t break anything with your “improvements” or it’s on you.
Also, all of this is going away soon, so make sure you don’t do anything unnecessary, like mocking all that data. (It’s been “going away” for well over a year now…)

So, we (I'm the backend guy and work with a UI dev) are building this product portfolio management tool for our client and they have a set of 250 users. The team has two point of contacts for the 250 users who maintain the master data, help users with data quality, tool guidance, reporting and other stuff. So one day one of these two support users come to me and say : Hey I'm not able to add new transactions coz a customer is missing.
We have the provision to create / maintain customers.
I check the production DB, application code, try creating the customer and then the transaction, everything works perfectly fine.
I ask the user for a screen sharing session, the user starts reproducing the error like this :
We have a 3 system landscape - Dev / Test and Prod
U : Logs into the test system url, creates the customer.
U : Points out the toast saying customer creation is successful.
U : opens a new tab, opens the production system, tries creating the transaction, searches for the customer and says " see !! cant find the customer here ! the master data management apps never work !! "

It's really funny to me that bitcoin can't be used for transactions anymore because it's way too volatile2

"What language should I learn?" Wellll.
[0]
43 PERCENT Of banking systems are built on COBOL
80 PERCENT Of in-person transactions use COBOL
95 PERCENT Of ATM swipes rely on COBOL code
220 BILLION Lines of COBOL in use today
"Experienced COBOL programmers can earn more than $100 an hour when they get called in to patch up glitches, rewrite coding manuals or make new systems work with old." [1]
Found this pretty interesting/crazy.

Me, working hard on a SQL project with a deadline that is half what it should be with no support from the other people on the project and was mostly made with with data I imagined would be in there cos no one could get me any fucking shit done (i.e. effectively designed, built, tested, fixed, upgraded, documented on my own for an entire weekly/monthly/ad-hoc analysis process that would output various reports for internal/external/management)
Manager - man who is a known waste of space but for some reason is in charge of the smallest part of the project, shouldn't have been fucking involved fucking management guzzling stain magnet...
Manager: Hey, do I need to refresh the database?
Me: .................
Me: .................
Me: ............I dunno, do you think we should refresh the database that this entire project is reliant? I mean...why do we need up to date transactions to analyse? Wait....you telling me it's not been being refreshed this ENTIRE time?
Manager: No....you never said I should. So should I?
Me: ..................I never said you should!?!? Are you not in the meetings talking about dependencies?????? Do you think i should have up to date trans or just run this with old stuff????? Why would you not update it!??!!?!?!? Its transactions...... (Desperately trying not to punch through my screen, through his, into his throat)
Manager: ..............
Me: .................
Manager: I think i'll refresh it and add it to the job?
Me: ....................(goes back to work cursing with music in so I think its quiet but who knows).
Tard, don't know how he even gets to work without someone holding his fucking hand.

Personal transactions application
Too much, just too much... -
Okay, so, my company does some stuff around blockchain. I had source for smart contract prepared before and it was on 'todo' queue. So, time for it, time to deploy on Kovan, time to test it on actual chain. Riiiight? Okay compiled no problem, deployed, no problem, i plug into several gui's ABI provided by compiler, and... Well..
I still do not understand why each and every gui prompted me to send view transactions (external view), instead of, well, eval them locally, i checked the ABI manually, it is correct, i stripped it down, it is correct, all up to spec.
I try older version of offline MEW, to have older web3.js with no success that thing works properly.
Every
Single
Web3.js based client
Behaved
Differently
And none behaved correctly.
I would, like, understand, if I didnt use official compiler, but official compiler should for F sakes be compatible with official client.
Today this stole 6 hours of my life, I didnt manage to solve it, and I am legitmitely pissed.
Im getting close to re-implement segment of web3JS to be able to do the tests I need to do.
Its not like I havent done it before.... -
O.M.F.G how much longer is that gonna take?!?! It's been 2 days already! 2 fucking days!!!
That's it. Fuck the docs. I'm going hardcore now: hooking up a debugger and diving into the unseen depths of Spring's automatic JPA repo initialization.
Unless any one of you knows how to
1. Manually create jpa repo interface bean
2. Make transactions work [also enable them manually by declaring beans in @Configuration]
and do all this in a single @Bean method. Jpa provider - hibernate.
Nobody? Not a single one? Allright then, I'm going in :(1 -
Another team didn't bother testing their code correctly, they passed us invalid values that another microservice needs, as a result they have a bunch of unstored data (that they would have seen wasn't being stored if they bothered checking the last stage of the process to see if it was stored). Now it's been so long that the data is expired. They want us to manually store millions of transactions for them.
Now tell me...if I came and shit in your bed, shouldn't I have to clean it up? -
Why the fuck is debit cards that don't need a PIN for transactions even a thing? What is so difficult to understand or implement in a two factor authentication? Like do these companies have meetings where some fucktard proposes removing a crucial security feature and the others just nod approval?6
-
Is There any good open source test automation frameworks testers can use to verify database insertions, such as message transactions? Everyday I get questions from testers to verify data and it's so tedious looking at MySQL tables to see if there data is present.4

How would you guys feel if your favorite app gave you 3 monetization options.
Crypto Mining at max 70% load
Giving you 100% privacy.
Ads, rip privacy, rip cpu.
Paid content /micro transactions
Rip wallet , some privacy concerns, happy cpu.
Thoughts?6 -
You can't make this shit up. Google it. WTF.

Question: Why are my <<Major Bank>> reports missing transactions, or why don't they reconcile?
Answer:

Data is missing from your <<Major Bank>> reports.
Cause
System issues at <<Major Bank>> can compromise the completeness of your report data.1 -
My visceral hate of Spring.Net burns with the force of a thousand suns.
Almost everything it does is done wrong or solved better by other solutions.
Specifying which classes to instantiate from .xml files? Sure why not, compile type safety (the whole reason for using a static programming language) is obviously overrated and dependency based injection is surely impossible!
And for extra bonus points, now our client code must be aware of the internals of the service classes, and all of their references as well, because, encapsulation? Who cares.
Have you made an typo? Good fucking luck finding out from which of the 100 config files we have floating around...
And, because it has baked in AOP and Transactions its woven into the fabric of the project like a tapewom.
Of course this may just be how our "special snowflake" project uses Spring.
What makes it more painful is that I love good DI tools (ninject, castlewindsor, autofac, there are so many...) and we're stuck with this turd because 7 years ago some java devs couldn't be arsed to learn a new library...1 -
!rant with a l'il rant at the end.
Anyone have any Android games they would recommend? I just want something to help me unwind, without being baited every 10 minutes into buying upgrades or coins or whatever.
In app transactions have ruined Android games for me. It drives me insane, but, I still would like something for when I'm not bothered to boot up my ps4 and spend hours living in The Witcher.4 -
How do you diagnose speed issues?
I've been lumped with looking after a legacy app.
It connects to our ERP system to handle raising invoices etc. And in June is developed slowness, which we sort of fixed by making one section load later (the SQL was a horrible view in a view in a view).
We then upgraded our ERP software, and the SQL issues are resolved (had to upgrade SQL server etc at the same time) and now the legacy app is running really slowly.
I know that it is when it loops through a data set to set column values etc.
A particular project has 1900 time transactions and takes upto 2 minutes to load.
This part of the program hasn't been changed in over a year, and has only started running slowly since the upgrade.
Are there any good way I can investigate and diagnose exactly why it has suddenly started running slowly?8 -
Deadline was 2-3 days for product launch and doing distributed transactions was not an opinion as it requires heavy modifications.
I was doing money transfer app between one transactional system and one not transactional system so the way I did it was :
1. transfer money from one system to my app that was using Akka STM ( software transactional memory)
2. try to transfer money to second system
3. transfer money back on failure
There was no database, no state only transactional log as installing database would require to much time and paper work.
Sometimes transfer back failed so we need to look back at logs and search for money, it was quite easy cause there was error and there were not so many failed transactions like this.
About one or two in a month and everyone accepted that.
I started to write some sort of reconciliation thread but then was assigned to other work and it worked like this for couple of years transferring couple millions worth of transactions.1 -
Did an assignment where we had to emulate deadlock using C and openMPI, I wanted to make a generalised resource manager process and create deadlock by locking some resources using the other processes, but my teammate said that would be too hard and instead the resource manager was hardcode with for loops for the number of transactions we were gonna make cause it was just a proof of concept.
Then my marker literally leads with, let me tell you the story of a good programmer, and a better programmer. The good programmer writes a function called destroy_earth(), but the better programmer writes a function called destroy_planet(earth) and passes in earth. I sighed so fuckin hard, I should have spoken up. -
An project I was working on was required to always identify users who took part in certain transactions (think of financial processing regulations).
Because some of the contacts on your phone might only contain a mobile phone number (and no name) a mandatory 'recipient' field was thus created to be filled for each transaction. This name was then checked against some international UN sanctions blacklists (you know, so Bin Ladens cousin can't use the thing...).
Only thing was... you could simply enter whatever name you wanted to. Like '%#^@/}(#' or 'John Doe', or 'Micky Mouse'... Everyone was well aware of this - but because ITS' THEM RULES we had to do it anyway.
Hope Bin Ladens cousin doesn't figure it out. :P -
Automate is a great app...

Semi addicted to a time waster mobile game that has micro transactions. Yet you can get free ingame currency by watching ads over and over.
Using automate i managed to 'automate' the process of "watch add. Click ok. Repeat"
Now when i sleep or idle ill just let it rake up some cash. Sadly it isnt full proof as sometimes (1 out of 20 times) it fails to run the ad and that breaks ot all. But restsrting it is easy and thats another 20 cash!
What have you done to skip tedious work for something trivial or some trivial gain but felt good you did it anyways?4 -
Hi guys! We are still searching for another dev to join our team for the hackathon hosted by Deutsche Bank in Berlin (late october). We're currently a team of 2: @ginjikoibito as iOS-/Backend-Dev and me as Designer.
So far the idea we want to apply with goes in this direction: Real-time evaluation of social structures through analyzing wealth & transactions provided by anonymized user-data of the API. It will also incorporate recognizable networks between users.
Sounds interesting? Please leave a comment, we're happy to share more with you :-)2 -
Released the product to customers without realising someone had pre-filled a production test accounted login at the login screen. Obviously it was used for testing purposes and the dev forgot to remove it before committing.
I loled when I found out about it, and some customers started to login and made transactions.
When I checked the commit history... It was under my name :/2 -
Screw our credit card processor so hard. The powers that be decided to sign with them because their rates were better. That's it. Never mind the fact that they don't make/work with mobile readers, which we need. Never mind the fact that their app is trash and is lacking basic features. Never mind the fact that their support is non-existent. Never mind the fact that when I request a new POS machine, I don't hear back for 6 months, and have to follow up again only to find they forgot about it. Never mind the fact that their POS machines can't handle 2 merchants like our ancient, "out-dated" one could, and so we need to spend double the money and have 2 POS machines sitting on the counter. Never mind the fact that their website is trash and lacks basic functionality. Never mind the fact that I cannot manage our user list (which changes CONSTANTLY), or even VIEW IT. I need to email them for all of this, and they may or may not respond. Never mind the fact that I'm going to spend my entire Friday scrolling through thousands of transactions, looking for one specific one, because their website doesn't even allow me to search for a specific transaction amount. Never mind all of that. Slightly lower rates, baby!1

Writing a test helper that handles all the fuckery with DB connections and transactions when the legacy under test uses multiple DB connections is so 👌👌👌👌👌👌👌👌👌👌👌👌👌👌
I can write tests for code that was untestable before 💦💦💦

On page 19 of the ethereum yellow paper: http://gavwood.com/paper.pdf it defines the address of a wallet as: A(pr) = Β[96...255](KEC(ECDSAPUBKEY(Pr))), which is the right most 160-bits of the Keccak hash of the public key generated by the private key.
If I expose the public key to the network, do I allow people to impersonate me and sign transactions even though they don't have Tr, Ts, or Tw? My understanding is no, that without those values you can't hash the transaction.
Subsequently, this leads me to wonder if the purpose of the address (besides identifying users) to obscure the public key so that the private key is at a less risk of being reversed? Or can the public key of any address be captured?
If the public key of any address can be identified on the network or off network (without actually being the owner of that key), how do you do that? Are there any resources on how to perform this that are computationally easy?1 -
Working with external teams on this new project involving pretty sensitive stuff like bank transactions.
Talking about user flow and how to handle authentication, like 2-factor and stuff.
Newish guy on external team (though experienced) says they have a proposal.

Ebay is a huge pile of freshly juiced garbage.
Their settings menu looks like its from 2005. And when it looks halfway decent the CSS doesnt load cause you have do not track enabled.
If you go to write their support, it returns an unexpected error.
when you use the shopping cart the number of items you have in it is not the same as the number it says that you have in it. And when you want to checkout that cart, not all items show up on the payment screen. Despite the item being shippable.
And the worst thing of them all: IF YOU THEN CHECK OUT ALL THESE ITEMS IT MAKES AN INDIVIDUAL TRANSACTION FOR EACH ONE. THUS THE FRAUD DETECTION OF THE CARD BLOCKS THE CARD, CAUSE TOO MANY TRANSACTIONS HAPPEND AT ONCE!2 -
! rant, needing advice
I'm about to start a big and ambitious project, and I'm stuck with a dilemma: what to pick for the back end server, node js vs Java JEE
The thing is that node is way faster than jee in concurrency transactions, which is a critical point for the program. But Java is Java.. I never worked on a huge app with JavaScript and it may become really messy..24 -
!Rant.
After reading many articles and watching YouTube videos on Blockchain, how it works, the new framework etc etc. It's evident that blockchain can be used to eliminate many problem faced in different industries and so on. What I cannot seem to find is a perfect application of solution to these problems in real life. I know it's too early to speculate, but thinking of all the internal(or under the table money) transactions happening, what is the possibility of mass adoption of blockchain given these conditions.3 -
Book: “Many cloud services choose not to implement distributed transactions due to the operational problems they engender.”

Related to the project in my last rant...
Project got delayed for about a month in total because the API for the payment gateway wasn’t allowing charges against stored cards. Could save, modify, and delete them, but no charges.
After a week of trying to get things working based on the documentation, I get in touch with the vendor (great people) who file a support request with the people running the processor so we can see what’s up. Long story short, that amounted to 3 weeks of getting ignored until the vendor raised hell on my behalf, only to get the following reply back:
“You’ve been using the dev credentials, try it on live transactions instead!”
Thankfully, we’re able to move the customer to another processor under the same vendor, where I already have all the requests figured out...2 -
I am creating a web api and I am stuck between using asp.net core 2.1 or nodejs' expressjs.
What is your take on this?
take this mind:
this service will also be responsible for processing transactions.7 -
It’s crazy that banks don’t have the technology to provide properly redacted bank statements. Will have to remove the labels of 13 pages of transactions by hand.1

Time to contest some credit transactions heh

Pretending to be the poor starving girl who's bitch mother ate everything she wanted from years ago I snuck food to is pretty fucking low10 -
What is your favorite method of debugging?
Mine is a debug log. I like a key value setting for enabling/disabling, and logging most transactions, calculations, and variables, even if they seem trivial. I've been able to locate bugs much quicker with detailed logs while some coworkers are still stepping through the process line by line. I don't fault the step method as I use it when logging uncovers nothing (it usually means I didn't log something critical :p) or when logging is not possible.1 -
Learn what blobs, trees, hashes and the concept of "commiting" (transactions) are.
Then learn how to use diff/patch.
Then learn Git.
In that order. -
I need to change how payments are applied to invoices.
ApplyPolicyPayments() looks promising! Make changes to the method to look at the bills in order of the invoice due dates.
Run a test on the DEV environment, and the system is still exhibiting the same bug.
At this point, I wrote a quick logging plugin that I could attach to the DLL and start telling me what is going on.
Turns out, payments are actually applied in a method named BalancePolicy(). So what does ApplyPolicyPayments() do? It DOES apply payments to bills, but then just doesn't save the work. Having it commit the transactions breaks the billing system. FML. -
I wasted 470 rupees ($5.6 USD) recharging on the wrong WiFi account, today.
😭 How's your Friday going? 😭
(I did ask Customer support if it can be refunded but they said No, it's not in the policy to refund these transactions).
It's a good thing I always chose 1 month recharge over 3, 6 or 12 months recharge, otherwise I'd have killed myself today.7 -
Tip: when doing transactions, don't pay as cash even if they tell you it is a requirement. Tell them you will pay via cheque or via bank transfer with a contract first with a seal from an attorney. You must have a valid copy first of the contract before doing payments. Also, get a photo of 2 valid IDs the person you are doing transactions. They require you personal infos and IDs? Require them also that.

A new version of a service request queue processor was deployed to test. It was supposed to have a performance boost compared to the previous version. The performance is so good that the new transactions are still locked when SRQP attempts to process their workload, so it ends up issuing empty transactions in another module. Artificial delay time...

2 years ago I would have hoped Discord would have started an enterprise version of their software but now it’s bloated with stupid paying gifs animations, activities and other cringe micro-transactions
Problem is there is no alternative of their role-based permissions system, or their open audio channels, or even the audio quality.4 -
Guys check out IOTA, get a light node wallet and buy some as long as it is still low. It is rising at a rising rate since some hours now.
IOTA is the solution to bitcoins speed and scalability problems. IOTA does not use the blockchain but instead a network called the tangle, which enables decentralized peer-to-peer transactions. There are no miners, no fees and the transaction validation speed depends on how many people are using the currency. One transaction requires your device to validate 2 other transactions through proof of work and therefore the system can never be overloaded by too many transaction requests.
Be warned though, the IOTA foundation is only currently building up the infrastructure, and people are just starting to trade since a few weeks so trasactions still may take a few hours.3 -
Who the fuck thinks that an private international api should have a limit of 5 tps (transactions per second) lol. Sadly I can't say the name but damn if I have 5 users just browsing our application, it will be throttled.
Mailed the guy why I need a lot more and now its very silent, really hope he can push the limit.5 -
Where is the best place, on an android app that lists user transactions, to place a sort & filter icon that will make an overlaying filter layout?

What does a bitcoin mining puzzle have to do with verifying transactions/driving consensus across nodes?
The winner just gets to write? The next block but doesn't that mean he is like admin, he can make up all the transactions he wants?22 -
You know
When I first saw etherum talking about am distributed state machine i thought wow. Not very practical but NEAT. I envisioned being able to make a byte code that could be stored in transactions and run by individual clients in an async function and each step of the resulting execution and the values of managed ram would be stored at intervals so other clients could take over and execute a few more statements and compare what should always be expected results that are identical
A grand incredibly inefficient system however really neato from the theoretical computer nerd standpoint !
Boy was I disappointed lol all it is a basic contracts language but yet they state it could be like a word computer ! How ? I thought maybe if you had enough nodes participating maybe you could store registers and the like in transaction values ? Wouldn’t that be the way ?
Seems like as a word computer they’re stuck somewhere between very simplistic js and something prior to amptron in usability yet they advertised as a world computer
Am i missing something ? I mean you could create something that would translate higher level code into smal numeric statements and then send it additions values but what would it be useful for and how would you actually. Store anything ? -
Like many of you, I'm always looking for good opportunities. I invested 124500 USDT in what seemed like a legitimate public sale, but the website crashed days before launch, leaving me feeling hopeless about my investment.

HOW TO RECOVER YOUR STOLEN BITCOIN, ETHEREUM OR OTHER CRYPTOCURRENCY WITH EXPERTS FROM SPARTAN TECH GROUP RETRIEVAL
I met someone on a dating app, and after chatting for a while, we started to get to know each other better. Our conversations soon turned to financial topics, and the person mentioned an opportunity to invest in cryptocurrency. They explained how easy it would be to make returns by sending crypto assets to a particular platform they trusted, which they claimed was based in Singapore. At first, I was skeptical, but the person seemed knowledgeable and convincing, so I decided to give it a try. They provided me with instructions on how to transfer my Ethereum (ETH), Bitcoin (BTC), and USDT to what appeared to be a legitimate banking app. I followed their directions carefully and sent the funds over in three separate transactions. Each time, the process seemed smooth, and I believed I was building a legitimate investment portfolio. However, after a while, I noticed something wasn’t right. The funds I had sent didn’t appear in the app, and my attempts to reach out for help went unanswered. The scammer started becoming more distant and evasive in their communication. That’s when I realized I had been scammed — the money I sent was gone, and I had no way to contact the supposed “banking app” or the person I had been communicating with. Feeling helpless, I decided to hire a specialized recovery service, SPARTAN TECH GROUP RETRIEVAL, which focuses on recovering lost crypto assets. They used blockchain forensic analysis to trace the transactions and eventually identified the scammer’s wallet. With their expertise, I was able to recover all my funds, which amounted to around 448,000 USD. While the ordeal was distressing and costly, I learned the hard way how important it is to be extremely cautious when dealing with online investments, especially involving cryptocurrency. It's crucial to thoroughly vet any platform or individual before sending money, as scams can be hard to detect. Thanks to SPARTAN TECH GROUP RETRIEVAL, I was able to regain my funds, and I hope my story can serve as a warning to others.

EY and ConsenSys announced the formation of the Baseline Protocol with Microsoft which is an open source initiative that combines cryptography, messaging and blockchain to deliver secure and private business processes at low cost via the public Ethereum Mainnet. The protocol will enable confidential and complex collaboration between enterprises without leaving any sensitive data on-chain. The work will be governed by the Ethereum-Oasis Project.
Past approaches to blockchain technology have had difficulty meeting the highest standards of privacy, security and performance required by corporate IT departments. Overcoming these issues is the goal of the Baseline Protocol.
John Wolpert, ConsenSys’ Group Executive for Enterprise Mainnet added, “A lot of people think of blockchains as the place to record transactions. But what if we thought of the Mainnet as middleware? This approach takes advantage of what the Mainnet is good at while avoiding what it’s not good at.”
