"Who the heck is the parent of this child?" -
I ask to myself when a button doesn't position itself relative to its container div as expected..
:/
In the end, it looks as it's supposed to, but the way it's done is just bad4 -
So, some time ago, I was working for a complete puckered anus of a cosmetics company on their ecommerce product. Won't name names, but they're shitty and known for MLM. If you're clever, go you ;)
Anyways, over the course of years they brought in a competent firm to implement their service layer. I'd even worked with them in the past and it was designed to handle a frankly ridiculous-scale load. After they got the 1.0 released, the manager was replaced with some absolutely talentless, chauvinist cuntrag from a phone company that is well known for having 99% indian devs and not being able to heard now. He of course brought in his number two, worked on making life miserable and running everyone on the team off; inside of a year the entire team was ex-said-phone-company.
Watching the decay of this product was a sheer joy. They cratered the database numerous times during peak-load periods, caused $20M in redis-cluster cost overrun, ended up submitting hundreds of erroneous and duplicate orders, and mailed almost $40K worth of product to a random guy in outer mongolia who is , we can only hope, now enjoying his new life as an instagram influencer. They even terminally broke the automatic metadata, and hired THIRTY PEOPLE to sit there and do nothing but edit swagger. And it was still both wrong and unusable.
Over the course of two years, I ended up rewriting large portions of their infra surrounding the centralized service cancer to do things like, "implement security," as well as cut memory usage and runtimes down by quite literally 100x in the worst cases.
It was during this time I discovered a rather critical flaw. This is the story of what, how and how can you fucking even be that stupid. The issue relates to users and their reports and their ability to order.
I first found this issue looking at some erroneous data for a low value order and went, "There's no fucking way, they're fucking stupid, but this is borderline criminal." It was easy to miss, but someone in a top down reporting chain had submitted an order for someone else in a different org. Shouldn't be possible, but here was that order staring me in the face.
So I set to work seeing if we'd pwned ourselves as an org. I spend a few hours poring over logs from the log service and dynatrace trying to recreate what happened. I first tested to see if I could get a user, not something that was usually done because auth identity was pervasive. I discover the users are INCREMENTAL int values they used for ids in the database when requesting from the API, so naturally I have a full list of users and their title and relative position, as well as reports and descendants in about 10 minutes.
I try the happy path of setting values for random, known payment methods and org structures similar to the impossible order, and submitting as a normal user, no dice. Several more tries and I'm confident this isn't the vector.
Exhausting that option, I look at the protocol for a type of order in the system that allowed higher level people to impersonate people below them and use their own payment info for descendant report orders. I see that all of the data for this transaction is stored in a cookie. Few tests later, I discover the UI has no forgery checks, hashing, etc, and just fucking trusts whatever is present in that cookie.
An hour of tweaking later, I'm impersonating a director as a bottom rung employee. Score. So I fill a cart with a bunch of test items and proceed to checkout. There, in all its glory are the director's payment options. I select one and am presented with:
"please reenter card number to validate."
Bupkiss. Dead end.
OR SO YOU WOULD THINK.
One unimportant detail I noticed during my log investigations that the shit slinging GUI monkeys who butchered the system didn't was, on a failed attempt to submit payment in the DB, the logs were filled with messages like:
"Failed to submit order for [userid] with credit card id [id], number [FULL CREDIT CARD NUMBER]"
One submit click later and the user's credit card number drops into lnav like a gatcha prize. I dutifully rerun the checkout and got an email send notification in the logs for successful transfer to fulfillment. Order placed. Some continued experimentation later and the truth is evident:
With an authenticated user or any privilege, you could place any order, as anyone, using anyon's payment methods and have it sent anywhere.
So naturally, I pack the crucifixion-worthy body of evidence up and walk it into the IT director's office. I show him the defect, and he turns sheet fucking white. He knows there's no recovering from it, and there's no way his shitstick service team can handle fixing it. Somewhere in his tiny little grinchly manager's heart he knew they'd caused it, and he was to blame for being a shit captain to the SS Failboat. He replies quietly, "You will never speak of this to anyone, fix this discretely." Straight up hitler's bunker meme rage.13 -
The idea was simple. Create a div.
Add two 50% div's inside. Float them. Add clearfix to parent.
Everything was fine.
Noticed that one of the childs had a height bigger than the other. But due to an adaptive design, setting static heights did not work.
Simple fix. Add a height to parent div and set overflow-y to hidden.
It didn't work.
Tried using the legendary !Important (a.k.a. not important but important.) Didn't work. Set position to relative, set static height. Set the childs to absolute position with height 100%. Problem solved.
No. It. Didn't. Fucking. Work.
Tried every possible css combination could could fucking think off.
After 15 minutes (8 hours in dev-stress mode) realized the clearfix changed the div DISPLAY TO FUCKING TABLE. A TABLE. FUCKING TABLES CANT HAVE FUCKING HEIGHTS FUCK.
Anyway. 6 years after my first clearfix. I learnt something new about the code that saves my life every project.5 -
I DID IT :D
I VERTICALLY ALIGNED A DIV IN CSS
I'm a noob in front-end development, I usually use bootstrap but now I did it in vanilla CSS inside ReactJs =D
or is it lol, I don't know, I used these:
position: "relative",
top: "50%",
transform: "translateY(-50%)"

This is what happens when you make style more important than function.
Pop quiz: when you lift the handle, what temperature water do you expect to come out? (This isn’t a trick question; assume you have an awesome water heater with instant warm-up time)
“Hot,” you might say, because the “H” is pointed towards you and aligned with the faucet.
“Cold,” you might say, because the handle is turned in the direction of the “C”.
There wouldn’t be any ambiguity if the H/C markings were on an immobile part of the fixture so that the relative position of the handle made the answer obvious.
(If you instinctively answered “cold” then congrats this is the perfect faucet for you.)14 -

I just want to share a small win in my career. finally, I got a 6-digit salary (relative to my country's currency)
the down side though, it's a .NET position10 -
dev, ~boring
This is either a shower thought or a sober weed thought, not really sure which, but I've given some serious consideration to "team composition" and "working condition" as a facet of employment, particularly in regard to how they translate into hiring decisions and team composition.
I've put together a number of teams over the years, and in almost every case I've had to abide by an assemblage of pre-defined contexts that dictated the terms of the team working arrangement:
1. a team structure dictated to me
2. a working temporality scheme dictated to me
3. a geographic region in which I was allowed to hire
4. a headcount, position tuple I was required to abide by
I've come to regard these structures as weaknesses. It's a bit like the project management triangle in which you choose 1-2 from a list of inadequate options. Sometimes this is grounded in business reality, but more often than not it's because the people surrounding the decisions thrive on risk mitigation frameworks that become trickle down failure as they impose themselves on all aspects of the business regardless of compatibility.
At the moment, I'm in another startup that I have significantly more control over and again have found my partners discussing the imposition of structure and framework around how, where, why, who and what work people do before contact with any action. My mind is screaming at me to pull the cord, as much as I hate the expression. This stems from a single thought:
"Hierarchy and structure should arise from an understanding of a problem domain"
As engineers we develop processes based on logic; it's our job, it's what we do. Logic operates on data derived from from experiments, so in the absence of the real we perform thought experiments that attempt to reveal some fundamental fact we can use to make a determination.
In this instance we can ask ourselves the question, "what works?" The question can have a number contexts: people, effort required, time, pay, need, skills, regulation, schedule. These things in isolation all have a relative importance ( a weight ), and they can relatively expose limits of mutual exclusivity (pay > budget, skills < need, schedule < (people * time/effort)). The pre-imposed frameworks in that light are just generic attempts to abstract away those concerns based on pre-existing knowledge. There's a chance they're fine, and just generally misunderstood or misapplied; there's also a chance they're insufficient in the face of change.
Fictional entities like the "A Team," comprise a group of humans whose skills are mutually compatible, and achieve synergy by random chance. Since real life doesn't work on movie/comic book logic, it's easy to dismiss the seed of possibility there, that an organic structure can naturally evolve to function beyond its basic parts due to a natural compatibility that wasn't necessarily statistically quantifiable (par-entropic).
I'm definitely not proposing that, nor do I subscribe to the 10x ninja founders are ideal theory. Moreso, this line of reasoning leads me to the thought that team composition can be grown organically based on an acceptance of a few observed truths about shipping products:
1. demand is constant
2. skills can either be bought or developed
3. the requirement for skills grows linearly
4. hierarchy limits the potential for flexibility
5. a team's technically proficiency over time should lead to a non-linear relationship relationship between headcount and growth
Given that, I can devise a heuristic, organic framework for growing a team:
- Don't impose reporting structure before it has value (you don't have to flatten a hierarchy that doesn't exist)
- crush silos before they arise
- Identify needed skills based on objectives
- base salary projections on need, not available capital
- Hire to fill skills gap, be open to training since you have to pay for it either way
- Timelines should always account for skills gap and training efforts
- Assume churn will happen based on team dynamics
- Where someone is doesn't matter so long as it's legal. Time zones are only a problem if you make them one.
- Understand that the needs of a team are relative to a given project, so cookie cutter team composition and project management won't work in software
- Accept that failure is always a risk
- operate with the assumption that teams that are skilled, empowered and motivated are more likely to succeed.
- Culture fit is a per team thing, if the team hates each other they won't work well no matter how much time and money you throw at it
Last thing isn't derived from the train of thought, just things I feel are true:
- Training and headcount is an investment that grows linearly over time, but can have exponential value. Retain people, not services.
- "you build it, you run it" will result in happier customers, faster pivoting. Don't adopt an application maintenance strategy

As I already said on devrant, I'm a freelance web developer and I also often sell my services for teaching, loving that. Currently I'm teaching PHP with 30 students and it's going very well.
But yesterday, I received an offer for giving another course next month, this time on HTML and CSS, for a company I don't know yet. Almost every line of this email is wrong, outdated by 20 years, or just basically meaningless...
So I thought I could do my best to translate this as close as possible to the original, preserving the wrong formulations too, just for you devranters fellas.
"Hello,
I have an offer for a 2 days course for 5 people (level 1+ and/or 2), on HTML5 and CSS3. Below, the program :
1. XHTML AND CSS2 INTRODUCTION
Advantages and benefits of change
Understanding compatibility for different versions of browsers

Relative and absolute measures units
2. LAYOUT TECHNIQUES
Full CSS, XHTML websites demo

Positioning elements with the help of Javascript : positionning elements relatively to the mouse, move elements
Show/hide elements for creating hierarchical menus
Code optimisation techniques : using objects, objects litterals, loops optimisation
Can you please give me your availability ?"
Seriously...
CSS-fucking-1 ! Is it a course for dinosaurs ?
...And if only my rant was just about the program...
It's totally impossible to cover all these subjects in only 2 days with people of different levels and experience.
The guy exactly said to me : "don't worry about the program, it's an old text but they agreed to it anyway. They just want to learn HTML and CSS, some of them already know it but want to learn more, and the others are total beginers.".
And here is the meaning for the "(level 1+ and/or 2)" part in the email.
So... Surprizingly, I accepted the offer, but asked for at least a 3rd day. I'm waiting for their answer, but I'll do it anyway, adapting the course content to the actual students knowledge. I need the money, after all.
Wish me luck...
It's just sad that these formation companies are selling bullshit to clients that just want to learn something useful. It's too often like that, they sell shitty/useless programs and we have to catch up in real time with students that don't understand why they don't learn what was told to them.3 -
Oh,I have learned a lot, I would not say from programming but from the career as a whole
Never get peer pressured
Always show empathy
If in a leading position, taking care of people is your top priority
Overconfidence will destroy a lot of good work
People by definition will always remember your mistakes
Never get over involved in the company you are working for, it's just a job
Your health is more than important
Nobody knows everything
Always be humble
There is a lot of bullshitters out there
Success is relative
Competition is high and there is always someone with better skill set, so you will suffer if you don't accept that -
So while exploring some new ideas, I decided to figure out if I could use variables in the known set to determine the bounds of variables in the unknown set.
The variables in question are algebraic identities derived from the semiprimes, so you already know where this is going.
The existing known set is 1194 identities.
And there are, if I recall, roughly two dozen unknowns.
Many knowns have the unknowns as their factors. The d4 product set for example is composed of variables d4a, d4u, d4z, d4z9, d4z4, d4alpha, d4theta, d4omega, etc.
The component variables themselves are unknown, just their products are known. Anyway.
What I've found interesting is if you know the minimum of some of these subsets, for example d4z is smallest out of the d4's for some semiprimes, then you know the upperbound of both the component variables d4 and z.
Unless of course either of them is < 1.
So the order of these variables, based on value, changes depending on the properties of the semiprime, which I won't get into. Most of the time the order change is minor, but for some variables they can vary a lot between semiprimes, rapidly shifting their rank in the known set. This makes it hard to do anything with them.
And what I found myself asking, over and over again, was if there was a way to lock them down? Think of it like a giant switch board, where flipping one switch lights up N number of others, apparently at random. But flipping some other switch completely alters how that first switch works and what lights it seemingly interacts with. And you have a board of them thats 1194^2 in total. So what do you do?
I'd had a similar notion a while back, where I would measure relative value in the known set, among a bunch of variables, assign a letter if the conditions were present, and generate a string, called a "haplotype."
It was hap hazard and I wrote a lot of code to do filtering, sorting, and set manipulation to find sets of elements in common, unique elements, etc. But the 'type' strings, a jumble of random letters, were only useful say, forty percent of the time. For example if a semiprime had a particular type starting with a certain series of letters, 40% of the time a certain known variable was guaranteed to be above a certain variable from the unknown set...40%~ of the time.
It was a lost cause it seemed.
But I returned to the idea recently and revamped the entire notion.
Instead what I would approach it from a more complete angle.
I'd take two known variables J and K, one would be called the indicator, and the other would be the 'target'.
Two other variables would be the 'component' variables (an element taken from the unknown set), and the constraint variable (could be from either the known or unknown set).
The idea was that relationships between the KNOWN variables (an indicator and a target variable) could be used to indicate the rank relationship between the unknown component variable and the constraint variable.
You'd think this wouldn't work either, but my intuition was there were so many seemingly 'random' rank changes of variables in the known set for any two semiprimes, that 1. no two semiprimes ever shared the same order for every variable, and 2. the order of the known variables had to be leaking information about the relationships of the unknown variables.
It turns out my intuition was correct.
Imagine you are picking a lock, and by knowing the order and position of the first two pins, you are able to deduce the relative position of two pins further back that you can't reach because of the locks security features. It doesn't let you unlock the lock directly, but by knowing this, if you can get past the lock's security features, you have a chance of using information about the third pin to get a better, if incomplete, understanding about the boundary position of the last pin.
I would initiate a big scoring list, one for each known element or identity. And then I would check it in tandem like so:
if component > constraint and indicator > target:
indicator[j]+= 1
This is a simplication, but the idea was to score ALL such combination of relationship, whether the indicator was greater than the target at the same time a component was greater than a constraint, or the opposite.
This worked out to four if checks and four separate score lists.
And by subtracting one scorelist from another, I could check for variables that were a bad fit: they'd have equal probability of scoring for example, where they were greater than the target one time, and then lesser than it for another semiprime.
So for any given relationship, greater or lesser between any unknown variable and constraint variable, I could find any indicator variable and target variable whose relationship strongly correlated to the unknown's.18 -
one of my friend is new to frontend dev.
and he's trying to center a div (text).
using position absolute and relative.
It's not working BTW.
We're communicating over text.
Must be loosing his mind.
He'll finally understand center div memes.6 -
Today on "fuck Firefox": elements with display: inline and position: relative completely mess up z-index and nested fixed / absolute positioned elements. It's a known bug, it has open issues on bugzilla since 2005, but still no fix. IE 8 can get it right, but not Firefox...9

I hate those mother fucking, Cock sucking, dick farting retarded faggots, who get the opportunity of a new job/internship just because they have a certain "relative" in the said company/organisation.
I mean its ok that you are getting an opportunity, but just don't act all-knowing-god-tier while you don't even know how to print a statement in c++ and got it.
How many more relationships should I increase of mine so that I get into the same position like them.
One of my friends got the internship just because his girlfriend's brother works for the firm.
Now that's just super barbaric unless he gave a blowjob to the gf's brother.
Their Fucking assholes need to be drilled by a giant pile drivers.5 -

Prequel to my previous post:
I received an offer from a startup that did not meet the originally advertised salary range. In every other aspect this place seemed like where I'd enjoy working the most and each previous interaction made a very good impression on me. So needless to say this was quite a shock.
They immediately apologised and explained the situation. They only now started to expand to and hire from my location (which can be verified) and I would be the very first person from this location (seems true too but I could only really verify this after joining). They explained the salary range I had seen was for their main hub location (accurate too) and said that the recruiter who posted the ad did not adjust it to mine. I asked why tf they didn't notify me of this earlier and they said they are super busy with everything, are new to location based salaries and normally don't check the recruiters posts as it should be her work.
Now, even if this is totally true, it was an awful sudden shock and felt a bit like a scam - totally contradicting my previous impressions.
Here are a couple of other points that I'll just sum to save time:
- before seeing the job ad I had a *reasonable* salary expectation even lower than their actual offering
- on the ad, the bottom end of their salary range far exceeded my reasonable exp.
- the relative level of my position would be even higher up the range that I have seen realised would be top 5%
- having had seen the ad, I started to have an *ideal* expectation being the bottom of the range
- in first interview I told them my exp. is the bottom end of their range +- a bit
- I told this to a dev guy who has no fucking idea about this stuff and I don't blame him but he noted this down to higher management
- generally I have not been very precise of my expectation as previously I only had lower class dev jobs, this would be the first decent.
- Hence I have seen an enormously high variation in salaries offered to me so this advertised range whilst high seemed possible
Now, with all this in mind I posted here a question about what some of you would do in my position.
I received the following group of responses:
- it's a scam, bad place, run
- it's an intentional (common) trick
- people make mistakes like this esp. startups so find out if this is intentional or not
- just decide if their current offering is reasonable for the position and location, ignore the rest
- just decide if the amount is enough
- location based salaries are retarded, don't work there (I kinda agree and also don't)
- if they can afford the higher pay in another place they should have no prob. meeting the range
- it's more important that you'd enjoy it there if the pay is sufficient for general needs
- company culture is generally more important these days
- fuck recruiters and hr people (amen to that btw)
Here is what I did:
Regardless of whether I believe them or not I hyperfocused on the potential scam/trick aspect.
I told them that every other interaction with them was positive and would love to join them but this was a really bad impression and feels like they are playing with me. I made up some bullshit previous examples of companies trying the same trick on me (which obv. never happened).
Then I said that I think to resolve this they should invite me to their main office for a day (all interviews had been online) and if after that they are still not ok to offer me at least the bottom of the adv. range then we can part ways. Otherwise this should ensure both of us that we are a good match, etc.
They seemed to love the idea and said that I should go there for x till y (3 days) and if we don't hate each other by the end I'll get the amount at the bottom of the range and they apologised again about it looking like a scam, etc.
So thanks a bunch again to those of you who provided valuable input. -
background-position works relative to its actual size (as in if you scale the background up 2 times, 256px have a whole different position).
like dafuq. how am i supposed to use that with pixels as units?4 -
A question on the CSS position property. I have a hard time understanding position, so I thought I would finally conquer it so that website development it easier.
Q.) Absolute removes the content from the flow and bases its position on the body, unless a container in the body has absolute, meaning the lowest level element finds the highest element that has absolute and bases its position from that and relative keeps it flow as if it was still there and moves relative to is current position in the documents as just a visual, as it does not move the other elements. Am I getting that correct?3 -
Since when did Entry Level turn into 3 years experience? WTF! To get an entry level job, I need experience, but to get experience, I need to get a job first... WTF...
A couple days back, I saw a junior position ask for 10 years experience in Javascript and HTML/CSS. Um. I'm sorry, WHAT?! Experience is so relative.. I could've learned HTML/CSS/JS 10 years ago and barely use it every year and still say I have 10 years of experience as opposed to somebody that learned it consistently in around a year. That person with 1 year experience would have more experience than me from the consistency with using these technologies. I just hate how employers will filter out resumes based on years of experience but it's getting better now, since you still have a chance if you don't have the "required" or "preferred" experience. -
