Testing for scientific purposes

What features would you want in a logger?

Here's what I'm planning so far:
- Tagged entries for easy scanning of log file
- Support for indenting to group similar sequential entries
- Multiple entry types (normal, info, event, warning, error, fatal, debug, verbose)
- Meta entries, so the logger logging about itself, e.g. disk i/o failures.
- Ability to add custom entry types, including tag, log-level, etc.
- Customizable timestamp function
- Support for JS's async nature -- this equates to passing a unique key per 'thread'; the logger will re-write all the parent blocks for context, if necessary. if that sounds confusing, it's okay; just trust that it makes sense.
- Caching, retries, etc. in the event of disk i/o issues.
- Support for custom writers, allowing you to e.g. write logs to an API rather than console or disk.

How about these features?
- Multiple (named) logs with separate writers (console, disk, etc.)
- Ability to individually enable/disable writing of specific entry types. (want verbose but not info? sure thing, weirdo!)
- Multiple writers per log. Combined with the above, this would allow you to write specific entry types (e.g. error, warning, fatal) to stderr instead of stdout, or to different apis.
- Ability to write the same log entry to multiple logs simultaneously

What do you think of these features?
What other features would you want?
I'm open to suggestions!

I promised a friend to have a look over his dads website to add a small blog. No big deal, I've got it on my drive, can reuse it just need to adapt it to the environment.

I take a look at what I'm working with and I see the most terrifying piece of "Please, take my data" code I could possibly imagine (And I've seen passwords, in plain text in a script tag). I quote "function queryDB(mode, val) {
var query=" ";
if(mode==="findProd")
query="Select * from Products where ProdNam=" +val;
... (same shit for different cases)
sendQuery(query) ;
}

He literally built the query on the client side sent it to a php script (without validation) and inserted it into the database.
You could literally call window.sendQuery with any sql query and get the result printed into the console.
And other than the plain text passwords guy that wasn't some kid someone knew, this was a "Webdesign" Agency.
Now I took the entire thing offline, called my friends dad, explained it to him and try to sort this out. I would not charge a good friends father but that hack will get a quite hefty bill since my hourly rate just tripled.

And the worst thing : If I publicly name that asshole or warn the people in his portfolio I can, according to Google, be sued. (But, and I assume thats vague enough not to count as bad mouthing, if anyone of you has a customer from Rheinland-Pfalz, Germany with a preexisting page, please have a look at the database interface)
I will call that agency tomorrow, ask for a detailed explanation for why they apparently let trained monkeys write their code and anonymously warn everyone in their portfolio about those flaws...

I don't know if I'm cursed or if there are just that many bad devs but it seems that once a year I have to stumble over some "mistakes" that make me question my sanity.

So..there is 2 of us working on a Wordpress site, my job is front-end and make it look nice, the other persons job is to do some backend development(dont ask me what and why, I have no idea). Basically, I was waiting for the other person to finish his part so I can do front end development. I was expecting it to be just a theme, and then I fix it, add new stuff, etc etc, like usually..but the horror I saw, THE FUCKING "BACKEND" PERSON HAS ACTUALLY MADE A FUCKING THEME EVEN THOUGH IT IS MY FUCKING JOB. Now dont get me wrong, I wouldnt mind if I did almost zero work and got paid, but..THE FUCKING THEME WAS UGLY AS A TWO HEADED DICK SMOKING A FUCKING CIGARETTE. There was STRONG RED FUCKING EVERYWHERE, padding between posts was basically -20px. Well ok, I could have just started making a new theme, but there was already some stuff in this one we needed so I went it it and tried to make it look nice. And trust me, it is great now, great colors, fonts, shadows, button animations, everything, even looks great on mobile.

I started making some changes to the header, and I noticed that post title changes also..hmm wonder why..So I inspect element and what do I see, TAG OF THE FUCKING POST TITLE IS <HEADER>???? WHAT THE ACTUAL FUCK, IF YOU TRIED TO DO SOME FRONT END, AND YOU SAY YOU KNOW SOME, WHY DO FUCKING FUCK WOULD YOU DO THAT???????? WHY THE FUCK WOULD YOU DO MY JOB IF YOU SUCK AT IT??? DONT DO MY FUCKING JOB, I SUCK AT "BACKEND" AND I DONT FUCKING DEAL WITH DATABASES OR TRY TO MAKE THEM FOR YOU!!!!! AAAAAAAAAAAAAAAAAAAAAAAARHHHHHHHH FUCK

What in the actual fuck GitHub?!

Why can't I edit a file direct on the web UI? I was able to this morning! If I can't edit against master then why the fuck is the icon there?!

Also, why did you add the unnecessary step of "add tag" when I am fucking CLEARLY adding a new fucking tag.

Man I'm annoyed!

TL;Dr what does it mean "we're trying to reduce options to a minimum", why don't you go closed source!? why don't you remove themes!?

For anyone who uses rofi, they would know that a few months ago an update made it more compliant with the free-desktop spec, that it only uses the first .desktop file for the given Name tag.

I only found out about this recently as I was only able to update Manjaro recently, and it really annoyed me, cause it took me a while to figure out why tons of my desktop entries disappeared.

Turns out someone made an issue about this, and the given answer was: "that's against the spec". Ok, fine. But when I asked if they could add an option to still ignore that aspect of the spec (i.e. --show-duplicated), the response I got was: "going against the spec is a no-go". WHAT!?

There are so many things that have behavior that goes against the spec (ex. gnu-utils), why can't they add an option to do this!? An OPTION!?

When I decided to try (I don't know C yet) and make a PR, the first and last (it got locked afterwards!) comment I got was:
" As explained on #941, this is a no-go. We want to reduce the number of options to the minimum, and non-compliance to a well-defined and widely implemented spec is definitely not something we want."

Why are you so closed minded!? Yes compliance is amazing, but it's not a safety standard, it's okay if you *give an option* to go against the spec!!!!

WHAT THE HECK!?!?!? WHY!?!?!?

Why is a open source project closed to new features that are part if the scope of the project, and require minimal maintenance!?

I have a platform idea, I need feedback

Problem statement: it’s hard to find researchers of specific area, which discourages students to even start looking for research opportunities. The reason for that is because people often look into their own academic circle, and the resource available is simply not enough.

Solution: by scraping Google scholar, generate detailed tag of sub areas for each professors, make a search system for that which will display the most important works of a researcher and what they are working on recently. If possible, invite the researchers to use the platform to add tags of traits they are looking for in students.

I have quite polarized feedback right now, one is the subarea tagging is really useful and academic circle is a problem, other is this is completely useless.

Please let me know what you think.

(tldr: are foriegn keys good/bad? Can you give a simple example of a situation where foriegn keys were the only and/or best solution?)

i have been recently trying to make some apps and their databases , so i decided to give a deeper look to sql and its queries.

I am a little confused and wanted to know more about foreign keys , joins and this particular db designing technique i use.

Can anyone explain me about them in a simpler way?
Firstly i wanted to show you this not much unheard tecnique of making relations that i find very useful( i guess its called toxi technique) :
In this , we use an extra table for joining 2 tables . For eg, if we have a table of questions and we have a table of tags then we should also have a table of relation called relation which will be mapping the the tags with questions through their primary IDs this way we can search all the questions by using tag name and we can also show multiple tags for a question just like stackoverflow does.

Now am not sure which could be a possibile situation when i need a foriegn key. In this particular example, both questions and tags are joined via what i say as "soft link" and this makes it very scalable and both easy to add both questions and new tags.

From what i learned about foriegn keys, it marks a mandatory one directional relation between 2 tables (or as i say "hard a to b" link)
Firstly i don't understand how i could use foriegn key to map multiple tags with a question. Does that mean it will always going to make a 1to1 relationship between 2 tables( i have yet to understand what 11 1mant or many many relations arr, not sure if my terminology is correct)

Secondly it poses super difficulty and differences in logics for adding either a tag or question, don't you think?
Like one table (say question) is having a foreign key of tags ID then the the questions table is completely independent of tag entries.

Its insertion/updation/deletion/creation of entries doesn't affect the tags table. but for tag table we cannot modify a particular tag or delete a tag without making without causing harm to its associated question entries.
if we have to delete a particular tag then we have to delete all its associated questions with that this means this is rather a bad thing to use for making tables isn't it?

I m just so confused regarding foriegn keys , joins and this toxi approach. Maybe my example of stack overflow tag/questions is wrong wrt to foreign key. But then i would like to know an example where it is useful
