Conversation today...
Guy: "Hey I need a real quick script to pull some values out of an XML document...is that possible?"
Me: "Uh...yeah that's pretty simple if that's all it has to do."
Guy: "Ok excellent I'll send you some files and documentation."
Me: "Ok so is this like a one time use thing or do you need to parse multiple of these?"
Guy: "Actually it needs to run all the time, on this specific PC, watch directories for any files that are added, then generate a XLSX files of the values, and also log information to a database. Etc"
Me: "Oh that adds quite a bit of complexity from what you originally said. It's going to take more time."
Guy: "But you said it was easy."
Well fuck you...12 -
We can't use a db so they give us a xlsx with this in one cell
=IF(AND(B4=D2;BJ4=E2);{B4:BK29};IF(AND(B4=D2;BH4=E2);{B4:BI29};IF(AND(B4=D2;BF4=E2);{B4:BG29};IF(AND(B4=D2;BD4=E2);
...
some others if

I think this is so far one of the most priceless WTF moments I encountered at my current work:
A coworker of mine came up to me explaining the problem he had with russian characters in the filename. He explained in detail that everything works ok (the other part of the code he was fixing) if he changes the name of the file to test1.xlsx for example which doesn't use russian characters. OK great.
Then he goes on to show me how he fixed the other stuff and of course everything blows up. The file he used for demonstration was of course the original file our cusotomer provided, he just deleted the obvious russian chars and left the rest.
МТС != MTC
I cracked up: but you still have russian chars in the name.
The guy: no way, I deleted them all.
Me: but what about that МТС in the name?! Guy: what about it?
Me: did you actually typed that in or you left it there?! Those are russian chars that are fucking things up for you.
Guy: no way, it's MTC.
Me: checked the logs, you have ??? In the filename instead of МТС..don't you find that at least a little bit suspicious?!
Guy: but it looks the same. How does it (the computer) know it is in russian?!? //Why doesn't it understand?!
O.o I still can't believe it.. Is it just me & my high standards, or should it be normal for coders to know things such as character encoding & stuff?!?
I almost died of laughter, he and some other guy had problems finding customers in the software due to not being able to type the russian chars << happened more then once before, even after I told them about a quick hack on how to use google translate onboard keyboard & other stuff to make proper chars so they can get a match..
I think when they bury me, I'll still be facepalming and laughing over this incident. 🤣🤣🤣🤣🤣🤣🤣7 -
Customer: Can you do a database query for me?
Me: Made the query and send them the result as a csv-file.
Customer: Is it possible to send it as an excel-worksheet because the columns don't have the right width.
Me: Resize the columns to the right width, saved it as xlsx-file and send it back.5 -
Well, for starters there was a cron to restart the webserver every morning.
The product was 10+ years old and written in PHP 5.3 at the time.
Another cron was running every 15 minutes, to "correct" data in the DB. Just regular data, not from an import or something.
Gotta have one of those self-healing systems I guess.
Yet another cron (there where lots) did run everyday from 02:00 to 4ish to generate the newest xlsx report. Almost took out the entire thing every time. MySQL 100%. CPU? Yes. RAM? You bet.
Lucky I wasn't too much involved at the time. But man, that thing was the definition of legacy.
Fun fact: every request was performed twice! First request gave the already logged-in client an unique access-token. Second request then processed the request with the (just issued) access-token; which was then discarded. Security I guess.
I don't know why it was build this way. It just was. I didn't ask. I didn't wanted to know. Some things are better left undisturbed. Just don't anger the machine. I became superstitious for a while. I think, in the end, it help a bit: It feels like communicating with an alien monster but all you have is a trumpet and chewing gum. Gentle does it.
Oh and "Sencha Extjs 3" almost gave me PTSD lol (it's an ancient JS framework). Followed by SOAPs WSDL cache. And a million other things.5 -
Hey everyone, cozyplanes here with another quick excel prank i thought of.
It is called TEEST, and the technique behind is simple, but interesting. Recommend taking a look, and pranking with your friends.
The following is the README of TEEST (Text in Excel Every Single Time) in Github.
You can check the simple project here ( https://github.com/cozyplanes/teest )
Disclaimer: Do not use or modify neither the program or the source code to make software violating the law.
### How do I use it?
1. Head to https://github.com/cozyplanes/teest and download the latest release `EXE` file.
1. Windows may warn you with the missing signature. The file is a DEBUG file, so there isn't a publisher signature. You can proceed downloading anyway since it has been virus checked by the developer.
2. Type the message you want to display in the textbox.
3. Click `Save text` button.
5. To check the file, click `Cancel` button in the opened popup dialog.
### What happens?
When an MS Excel file (`.xlsx`) has been opened, by using TEEST, two files gets opened.
1. The original file user opened
2. Excel file named `message.txt` with the custom message you have written.
`message.txt` excel file will open every single time a person opens a excel file.
*In some older versions of Excel, the message may overlap with the user opened file.*
### Why does this happen?
When MS Excel program is executed, it is programmed to check the files in the following 2 folders.
- `C:\Program Files\Microsoft Office\Office[versionnumber]\XLSTART`
- `C:\Users\%username%\AppData\Roaming\Microsoft\Excel\XLSTART`
In normal conditions, there is no file in those folders (or the folders doesn't exist at all) but when you use TEEST and click `Save text` button, it saves `message.txt` file in the folders above. From MS Excel is executed again, it will find out there is a file in the folders above, so it will show those text files in Excel.
### Where is this technique used?
There should be a lot of software using this trick, but it is widely known for ransomwares such as `GandCrab` and `TeslaCrypt` displaying decryption methods in MS Excel by this trick.
### How can I disable it?
1. Open TEEST again.
2. Click `Save text` button and click `Cancel` in the following popup.
3. Delete `message.txt` file in the opened explorer.

I would like to know if anyone has created a CSV file which has 10,000,000 objects ?
1) The data is received via an API call.
2) The maximum data received is 1000 objects at once. So it needs to be in some loop to retrieve and insert the data.11 -
Today my boss decided that he wanted to manage his project properly. After a year he gave us deadlines (we still had deadlines but usually we did not know them). I open the xlsx file (yeah... xlsx) and I see the date of today as deadline. Well, at least it won't be a surprise this time.2

When I asked the client if they have an existing API with xml or json, they said that they will send me Excel xlsx per email.3

We recently hired a new developer, fresh from uni. Very little real experience as I can see.
Unfortunately I weren't available for the interviews, so they chose a dev without me.
All his code is messy, over complicated and uses symfony framework for _everything_
He can't do shit outside of it.
He was tasked to find and replace some links in a few hundred excel documents, he spent ages trying to parse the xlsx documents and the replace the links and write to the document. Spent all day on it, with no results. Even though I often asked him how he was getting on, he said all was fine.
End of day, I get a tad furious, whip out my terminal and do the whole task in 10 minutes with basic bash4 -
I am a Technical Lead in the department in my company that writes code for our clients that have money but doesn't have the technical expertise to handle the complexities of our own software.
Part of my tasks involve taking care of a few projects written by employees that have left after using third-party tools rather than using our own software. No one else in this department knows these third-party tools, they only know our own, and my *still limited* web development experience means I get dumped these things in my lap.
And I'm SO pissed at these projects and their authors and the manager that let these ex-employees write these things. There is this one project that was managed by two different "developers" (I don't know they deserve this title) at two different times, and it is so riddled with different technologies it makes me want to throw up almost daily.
Don't believe me? Here is a complete list of the dependencies listed in the package.json of this project: babel-polyfill, body-parser, cookie-parser, debug, edge, edge-sql, excel-to-json, exceljs, express, html-inline, jade, morgan, mssql, mysql, pug, ramda, request, rotating-file-stream, serve-favicon, webpack, xlsx, xml2js
What this doesn't even show, is that one part of this project (literally one page) is made using react, react-dom, react-redux, and jade. The other part (again literally one page) is made using Angular and Pug. In case you missed it while picking up your jaw, there's also mssql, mysql, edge and edge-sql. excel-to-json, exceljs, xlsx.
Oh you want *more* juicy details? This project takes the entire data object used by the front-end, stringifies it into JSON, and shoves it into the database *as a single field*. And instead of doing WHERE clauses in the SQL queries, it grabs the entire table, loops, parses the json, and does a condition on it. If even one of those JSON entries gets corrupted, the entire solution breaks because these "developers" don't know what try/catch is.
The client asked for a very simple change in their app, which was to add a button that queries the back-end for a URL, shows it in a modal dialog, after which a button is clicked to verify the link by doing a second query to the back-end before modifying a couple of fields in the page.
This. Took. Me. Two. Months*. Save me. Please, save me.
*between constant context switches between this and other projects that were continuously failing because of their mistakes.4 -
when the client sends you a long and very detailled/structured .xlsx to explain fixes... and it turns out it's just a typo in the footer.

Our software outputs some xml and a client has another company loading this xml into some data warehouse and doing reporting on it. The other company are saying we are outputting duplicate records in the data.
I look and see something like this:
<foo name="test">
<bar value="2" />
<bar value="3" />
</foo>
They say there are two foo records with the name test..
We ask them to send the xml file they are looking at. They send an xlsx (Excel!) file which looks like this:
name value
test 2
test 3
We try asking them how they get xlsx from the xml but they just come back to our client asking to find what we changed because it was working before. Well we didn't change anything. This foo has two bar inside it which is valid data and valid xml. If you cant read xml just say so and we can output another format! -
4 hours wasted due to a rather strange "scope poisoning" bug... it was really fucking strange.
Had to move the 5 lines of code, above where the error happened, to a private function.
The 5 lines just called an XLSX library which read a given file and returned an array. I don't know how but the thing somehow messed with my Soap client call one line below. The culprit must have been some IO resource handle which didn't get destroyed when in the same scope due to persisting object references..1
