Search - "regression"
Buzzword dictionary to deal with annoying clients:
Dark web—Onion service
Data science—statistics done by nonstatisticians
I just started playing around with machine learning in Python today. It's so fucking amazing, man!
All the concepts that come up when you search for tutorials on YouTube (you know, neural networks, SVM, Linear/Logic regression and all that fun stuff) seem overwhelming at first. I must admit, it took me more than 5 hours just to get everything set up the way it should be but, the end result was so satisfying when it finally worked (after ~100 errors).
If any of you guys want to start, I suggest visiting these YouTube channels:
At one of my former jobs, I had a four-day-week. I remember once being called on my free Friday by an agitated colleague of mine arguing that I crashed the entire application on the staging environment and I shall fix it that very day.
I refused. It was my free day after all and I had made plans. Yet I told him: OK, I take a look at it in Sunday and see what all the fuzz is all about. Because I honestly could fathom what big issue I could have caused.
On that Sunday, I realized that the feature I implemented worked as expected. And it took me two minutes to realize the problem: It was a minor thing, as it so often is: If the user was not logged in, instead of a user object, null got passed somewhere and boom -- 500 error screen. Some older feature broke due to some of my changes and I never noticed it as while I was developing I was always in a logged in state and I never bothered to test that feature as I assumed it working. Only my boss was not logged in when testing on the stage environment, and so he ran into it.
So what really pushed my buttons was:
It was not a bug. It was a regression.
Why is that distinction important?
My boss tried to guilt me into admitting that I did not deliver quality software. Yet he was the one explicitly forbidding me to write tests for that software. Well, this is what you get then! You pay in the long run by strange bugs, hotfixes, and annoyed developers. I salute you! :/
Yet I did not fix the bug right away. I could have. It would have just taken me just another two minutes again. Yet for once, instead of doing it quickly, I did it right: I, albeit unfamiliar with writing tests, searched for a way to write a test for that case. It came not easy for me as I was not accustomed to writing tests, and the solution I came up with a functional test not that ideal, as it required certain content to be in the database. But in the end, it worked good enough: I had a failing test. And then I made it pass again. That made the whole ordeal worthwhile to me. (Also the realization that that very Sunday, alone in that office, was one of the most productive since a long while really made me reflect my job choice.)
At the following Monday I just entered the office for the stand-up to declare that I fixed the regression and that I won't take responsibility for that crash on the staging environment. If you don't let me write test, don't expect me to test the entire application again and again. I don't want to ensure that the existing software doesn't break. That's what tests are for. Don't try to blame me for not having tests on critical infrastructure. And that's all I did on Monday. I have a policy to not do long hours, and when I do due to an "emergency", I will get my free time back another day. And so I went home that Monday right after the stand-up.
Do I even need to spell it out that I made a requirement for my next job to have a culture that requires testing? I did, and never looked back and I grew a lot as a developer.
I have familiarized myself with both the wonderful world of unit and acceptance testing. And deploying suddenly becomes cheap and easy. Sure, there sometimes are problems. But almost always they are related to infrastructure and not the underlying code base. (And yeah, sometimes you have randomly failing tests, but that's for another rant.)9
What is it with clients who have never even seen a single line of code in their entire lives telling me how long they believe a certain change request should take to code.
I mean, what if I told you that your "seemingly simple enough" change needed an update to 36 class files, 9 oracle stored procedures AND several database schema changes. Also, who the fuck is going to perform a regression test to make sure I didn't break anything? Your Uncle Bob??6
Ooh this is good.
At my first job, i was hired as a c++ developer. The task seemed easy enough, it was a research and the previous developer died, leaving behind a lot of documentation and some legacy fortran code. Now you might not know, but fortran can be really easily converted to c, and then refactored to c++.
Fine, time to read the docs. The research was on pollen levels, cant really tell more. Mostly advanced maths. I dug through 500+ pages of algebra just to realize, theres no way this would ever work. Okay dont panic, im a data analyst, i can handle this.
Lets take a look at the fortran code, maybe that makes more sense. Turns out it had nothing to do with the task. It looped through some external data i couldnt find anywhere and thats it. Yay.
So i exported everything we had to a csv file, wrote a java program to apply linefit with linear regression and filter out the bad records. After that i spent 2 days in a hot server room, hoping that the old intel xeon wouldnt break down from sending java outputs directly to haskell, but it held on its own.1
So our service has a 9% test coverage (that 9% was from me sneaking tests into my PRs, before I arrived there was only one test and it was assertTrue(True)) but they won't allow me to take some time to go and write the regression tests myself.
Now whenever I make a change to the service and I get asked how sure I am that I won't introduce regression I look them dead in the eye and say "9% sure". One day they'll get tired of it and let me write tests5
I am staying late tonight because some dummy deployed their minor fix to one of my devices in the middle of a 3 hour regression, forcing me to restart it.
A month ago. The code for a feature was removed because my boss thought it would not be required. When that was done, a lot of regression testing was done and a lot of code was changed all over the code base. And those changes were merged to main branch along with a bunch of other changes.
But now, he wants me to put that feature back just as the release date is approaching. It's just a humongous waste of time. Now I need to find where all the tentacles of that bloody feature reach and manually put back the code. And the bloody testing needs to be done all over again.
When will I get to stop dealing with these kind of people.9
Hey, if you buy my algorithm and dont actually hire me (not that i would have accepted anyway), dont fucking spam my phone 2 months later to explain a fucking regression to your msc students who seem to have learned jackshit @ college.
How many times do I have to tell my co-workers that testing isn’t just about proving your shit works in nice ways. It’s also about proving it works with sparse or inadequate data. Also, regression testing is a thing so do it!2
i'd rather burn a site to the ground to preserve it in its current state than let it devolve into a place for SJWs to basically outlaw everything because they're special snowflakes. It's about breaking video games, you don't need to say "well you can't use he/she/him/her pronouns ever, you can't acknowledge binary genders, you can't say the word 'retarded' even when referring to the dictionary definition of the word (synonym of regression), you can't send PMs at all because privacy is against God, you can't say/reference God or Christianity because #NotAllReligions"
just fuck off. We break Pokemon games, we don't plot to genocide the white race because all whites are cis racist Nazi cucks like you do goddammit
Dev nightmares :
- Not finding bug fix on stackoverflow/GitHub .
- Losing code that hasn't been pushed to GitHub.
- Dealing with an unclean and inconsistent database.
- Installing Node Dependencies.
- Resolving CORS and 500s.
- Training a Linear Regression Model with 700 epochs on an entry-level Laptop.
Keep appending to this list.
I seriously thought I was losing my mind this morning.
Loaded up my IDE and got to work.
Needed to find something in the project, so I hit the keyboard shortcut to find all usages in the project path.
The dialog pops up, but my selection is replaced with a long hex string. I thought it was weird, but I just installed the latest update of my IDE so I thought I'd found a regression. I grabbed the hex string and went over to Google to see if anything useful popped up.
The first result is the reddit post for my keybase key.
Wait. The "random" hex string was the fingerprint for my keybase public key? I double-checked to make sure that keybase wasn't running and I didn't have anything weird hanging out on my clipboard. Nothing amiss, but I still got my key whenever I searched for something.
This is the point where my brain got a little melty. I started running weird conspiracy theories in my head. My ever-helpful coworkers could only suggest to "stop using a Mac".
I saw that the app menu got highlighted when I opened the dialog, so I opened the menu and looked at the Services. Lo and behold, the GPG Suite update I installed recently very "helpfully" added a global shortcut to "Insert My Fingerprint" with the same keyboard shortcut as the IDE action.2
Most recently... taking something previous devs had failed at and knocking it out of the park.
Best example was a statistical regression and graphing tool on ASP MVC.
The devs were doing a massive brute force recalculation on the server layer. It would take 24h then fail to save (Entity framework brute force).
We moved it to the database layer and got it down to a passable time.
The same devs were outputting charts to ie 9, chrome, firefox... same deal, half an hour on the initial request (parser churn in the browser)... then failure.
Again got it into a passable time by switching to web sockets and long polling then outputting 1000 or so points at a time to give the browser time to render.
Taking those two cock ups and making them a workable solution was awesome.
Since then, teaching. We have apprentices, newcomers, interns all jumping in and looking to get working. They're all different, what works to teach one person won't the next, each of them so far has caught on to what I was teaching. It's a proud moment to be able to impart knowledge and see someone pick it up, enthusiastically... it's also awesome to see someone excited about what you do.
Annoying Indian professors are everywhere. It's a computer vision class are you really teaching us Regression?
What about transfer learning? object detection! Give us papers to read, let's do projects.. what the hell is this I am going take attendance bullshit and teaching crappy concepts.
I did not sign up for this shit! I came here for my Masters to get away from pompous mother fuckers like you ...
My class is also filled with those idiots,who think bias in a neural network is somehow related to class imbalance ? Now the same idiot proceeds to ask questions like...
Why would the weights change in a neural network?
Motherfucker why you in this class ? Why don't you stick to your shit and ask these questions later..
I am so pissed off right now guys ...
I was sitting in my lab understanding the deeper insights of BN, activation fucntions.. various optimizers ..etc Stuff that this idiot motherfucking teacher must be covering... UGGH.
I shouldn't cuss so much.. or at least add variety to my cuss words..
I am pissed off cuz instead of learning the shit I should be learning I am forced to come and attend this class and waste 2 hrs of my life ...
It's the summer i find it hard to focus anyway (want to go out hiking or swimming or something.) BUT. the moment I find some resolve to focus
I get this fucking bullshit.. !
My mind is so fucked right now... I can't think of anything but standing up in class and screaming " Mother fucker, mother fucker...(point to the idiots in class you) motherfuckers shut the fuck up..
Can someone suggest some colorful swear words ?
My brains not working -_-
It is just about now that I start feeling like "Anger" from inside out12
qa: so yesterday we found some bug, not really related to you but <boss> told me to put it on you
me: yeah, when he doesn't, this dick didn't work since I came
*later this day at ~15:00*
boss: so I'm going home, you **must** deal with this bug today, your algo doesn't work.
me: it did 2 days ago didn't it? did you even check the bug?
me: did you check for regression or just said to put it on me?
me: did you check the changes of the new guy?
me : so why the fuck blame my code?!
*17:10 I'm going home no regression, new guys code deadlocks, not a single fuck thrown*
TLDR: Walmart bug 😠
As a dev, I know that bugs happen. But as a dev from a small shop that has many clients and very few devs, I absolutely despise when a large company with many devs has a bug in a product that millions of people use.
WalmartContacts.com. How many devs do they have? And how many dedicated to this 1 product? How many people in QA? (how many on DevRant... lol)
And yet I can't even place an order using their reorder functionality. Seems like they should have this shit down. Seems like they should have all their regression testing ducks in a row. Seems like they should at least show some kind of error message so the user knows what's going on. Instead, no message at all, just the final checkout payment page reloading when I submit leaving me to wonder if my card has been charged or not.3
my company is "pivoting" way too goddamn fast; they are pulling devs from other projects and throwing them into something that is a fragile system (was supposed to be replaced already) and is using a completely different stack than most of them usually work with. they keep promising 3rd parties that we will knock out their requirements within a week or two, and as such they are pushing haphazardly merged feature branches into production with absolutely no regression testing.
then when shit explodes and operations grinds to a halt, they tell the half of the team that actually knows how the system works to drop everything and fix it, and leave the diverted devs to continue to develop shit based on requirements drawn on a cocktail napkin, and then they fucking push both the hotfixes and the newest features at the same time.
I probably have the most tribal knowledge at this company, and they are paying me ok, so it's enough for me to just pour some rye and suck it up for the time being and milk the gig. but this can't be sustainable, right? i'm passively looking around for other work, as I've already had enough being here for over 3 years, but i'm finding most places to be slow on the application/hiring process lately due to covid.
Edit: i think i used the wrong tag here, but what the fuck ever. i haven't figured out how to tag shit properly on any platform3
After building some automated regression tests to verify parts of the company website were working, it was discovered that a test case was missing.
Instead of a constructive meeting about fixing the issue and adding a test, I was reamed and my manager was reamed that we "missed this case".
Nevermind that the automation caught several issues before release in nearly every other aspect of coverage.
Nevermind that the missing test case was a useless feature added after the automation was completed.
Nevermind that automation was meant to be the last stop in the gate, not the first...
I was so livid after that meeting I nearly resigned on the spot. My manager was so livid over being told to write me up he was ready to resign.
When you’re fundraising, it’s AI
When you’re hiring, it’s ML
When you’re implementing, it’s linear regression
When you’re debugging, it’s printf()3
Reminds me of some of our testers, who raises similar bugs, if they don't get any issues in regression testing.
Wish me luck. Looks like the feature I am developing is going to be late because QA doesn't feel like following the estimates we agreed on. We already identified that development was going to be the longest part of this whole effort and that QA was going to be relatively easy, but but no. Because this is the day we have to be "code complete", they don't want to test a relatively simple feature. In fact we had to talk them into even starting testing on it today. Even though regression day is Monday and they are basically going to be done testing their last ticket this morning. Like what the fuck were they going to do for the next 7-8 hours? They don't write any documentation. There are no reports to do. There are no meetings. Did they just want a virtual day off?
Edit: they are literally playing with people's careers here. This is not the first time I have had something delayed by QA even though they agreed that it was simple to test and it was delivered with enough time to fucking test. Then I get in trouble because of late delivery.6
Caused my first regression. Being sarcastically congratulated by co workers. Cant describe the feeling in any emotion possible and known to homo sapiens.1
Tl;Dr Im the one of the few in my area that sees sftping as the prod service account shouldn't be a deployment process. And the ONLY ONE THAT CARES THAT THIS IS GONNA BREAK A BUNCH OF SHIT AT SOME POINT.
The non tl;dr:
For a whole year I've been trying to convince my area that sshing as the production service account is not the proper way to deploy and/or develop batch code. My area (my team and 3 sister teams) have no concept of using version control for our various Unix components (shell scripts and configuration files) that our CRITICAL for our teams ongoing success. Most develop in a "prodqa like" system and the remainder straight in production. Those that develop straight in prodqa have no "test" deployment so when they ssh files straight to actual production. Our area has no concept of continuous integration and automated build checking. There is no "test cases", no "systems testing" or "regression testing". No gate checks for changing production are enforced. There is a standing "approved" deployment process by the enterprise (my company is Whyyyyyyyyyy bigger than my area ) but no one uses it. In fact idk anyone in my area who knows HOW to deploy using the official deployment method. Yes, there is privileged access management on the service account. Yes the managers gets notified everytime someone accesses the privileged production account. The managers don't see fixing this as a priority. In fact I think I've only talk to ONE other person in my area who truly understands how terrible it is that we have full production change access on a daily basis. Ive brought this up so many times and so many times nothing has been done and I've tried to get it changed yet nothing has happened and I'm just SO FUCKING SICK that no one sees how big of a deal this. I mean, overall I live the area I work in, I love the people, yet this one glaring deficiency causes me so much fucking stress cause it's so fucking simple to fix.
We even have an newer enterprise deployment. Method leveraging a product called "urban code deploy" (ucd) to deploy a git repository. JUST FUCKING GIT WITH THE PROGRAM!!!!..... IT WAS RELEASED FUCKING 12 YEARS AGO......
Please..... Please..... I just want my otherwise normally awesome team to understand the importance and benefits of version control and approved/revertable deployments2
Not writing tests for your code is like leaving it unguided in the hands of future Devs who gonna just change something and break the core logic and there won't be any regression test to run and check the integrity.
...This algo can predict new thermoelectric material discoveries years in advance...
Me to all material scientists : "Work harder or we'll replace you with AI".
P.S : I also need to work harder as I barely know the surface of Linear Regression.1
I decided to upgrade my intellij ultimate from 2019.3 to 2020.2 and I saw there is update button.
I clicked on it.
As I expected it didn’t work and it was 30 minutes waiting looking at progress bar going back and forth couple of times before I decided just to download latest version and drag and drop it to applications folder ( took me 5 minutes) - I use mac so it replaces all crap ( I think ).
I cleared the old cache that growed to 2 gigabytes leaving some configuration files.
Next as always crash on startup cause of incompatible plugins with long java stacktrace - at least I could click the close button or popup closed itself I can’t remember ( one version I remember this button couldn’t be clicked cause it was off the screen and you need to do some cheating to launch ide )
The font has changed and I see that it at least work a little faster - that is nice. Indexing is finally fixed after all those years - probably thanks to visual studio code intellisense pushing those lazy bastards to deal with this.
But the preloader on first logo disappears so I think they decided to remove it cause it’s so fast - no it loads the same time or maybe little longer when I launch it on my old macbook.
After that as always I looked at plugins to see if there’s something interesting, so to find ability to scroll over whole plugins I needed to click couple of times. I think they assume I remember all the nice plugins in their marketplace and I only type search.
Maybe I should be type of user who reads best 2020 plugins for your best ide crap articles filled with advertising or even waste more time to watch all of this great videos about ide ( are there any kind of this stuff ? )
After a few operations I unfortunately clicked apply instead of restart ide and it hanged up on uninstalling some plugin I’m no longer interested in for 5 minutes so I decided to use always working ‘kill -9’ from command line.
Launched again and this time success.
Fortunately indexing finished for this workspace and I can work.
I’m intellij ultimate subscriber for 7+ years and I see those craps are not changing from like forever.
What’s the point of automate something that you can’t regression test ?
I started thinking that now when most people are facebook wall scrolling zombies companies assume that when new software comes out everyone is installing it right away and if not they’re probably not our customers cause they’re dead.
What a surprise they have when I pay for another year I can only imagine ( to be fair probably they even don’t know who I am ).
Yeah for sure I am subscribed to newsletters and I have jetbrains as a start page cause I shit myself with money and have nothing better to do then be grupie ( is there corporate grupies already a big community? )
Well I am a guy who likes to spend some time when installing anything and especially software that is responsible for my main source of income and productivity speed up.
Anyway I decided to upgrade cause editing es7 and typescript got to be pain in the ass and I see it’s working fine now. I don’t know if I like the font but at least the editor it’s working the same or maybe faster then the original that is huge improvement as developers lose most of their time between keyboard and screen communication protocol.
I don’t write it to discourage intellij as it’s great independent ide that I love and support for such a long time but they should focus on code editor and developers efficiency not on things that doesn’t make sense.
Congratulations if you reached this point of this meaningless post.
Now I started thinking that maybe it’s working faster cause I removed 2 gigs of crap from it.
Well we’ll see.1
Worked all day yesterday (8am to 11pm) trying to get a regression test developed in ReadyAPI to behave properly in Maven/Jenkins. All I have to say is that I have some words for Smartbear.
(disclaimer: this might sound like a 13 year old guy just coming out from a theater after watching matrix but in some ways, its not )
Why the fuck should i feel discouraged from getting into ml/ai by all these smart ass people continuously taunting that "yeah, you might get into ml/ai but you won't get successful if you have a bad maths"
Ok, 1) i totally agree with these guys. Checked some pages and everywhere itse regression ,linear something, nlp's and neural networks, which even by the name sounds full of maths. BUT here is a thing:
1) All i can think of this as an ocean: just like web development is so vast, android is so vast, i can assume this to be so vast too.
BUT I WANT TO APPLY IT, NOT MAKE IT! why? Because that's what a beginner would do. It's data "sciences" and ppl who are deep into it will be called data "scientist" , a fuckin doctorate profession!
And toda i see it at so manypaces : from alexa playing song to google searches , youtube recommendation, hell even coffe machines are getting smarter!
I like these things and want to apply them as a developer to my apps and websites. But tell me, do everyone making a scanner or search engines learns regression algorithms and lambda calculas?
I love automation. So much that if given a chance, i would make robot to fuckin suck me off! From smart searches , self driving cars, map routes to latest apps with awesome pattern recognitions, i love them all. What i want to do is to look at some codes, tweak them for my usage and make something extraordinary and automated machine learning from ussr's interaction. I don't think my interest to learn applications of a technology and not the technology itself should be considered wrong because both are a carreer in their own! Learning ml/ai vs learning their applications is like a learning physics vs learning furniture designing: one being a part of other but completely existential on its own .
Thus the question comes what should i do? I got attracted by ML's achievements and fireworks but every ml course wants me to be the cracker maker! I want to get into data sciences bcz of its achievements ; and i want to replicate them again nd again until get termed as a professional nd if i feel the urge, maybe re visit my collage books and read maths and get into nlp designing (or whatever)
Where to get knowledge of this "life automation technologies" / data sciences (if they both are rea equal) and knowledge of such "ml toolkits" , if its really possible to be into ml without maths?8
Ugh... some people...
Just left the office early because of the toxic climate. That one infamous collegue is basically unable to communicate without being a narcissistic 5-year-old and was arguing whether we should write a test (I was going to write the test) that would need a single additional branch in the build system.
(The test was for a parser and it should test whether it can handle absolute paths. A simple regression test with a file and an expected output. Because absolute paths are different for every platform and user, the files to be parsed would have to be generated with appropriate paths before the tests were run. Well that would require one single python script and a single line in the script that runs the script and DONE)
Well that guy was unable to focus on his own work and started an argument about whether that test was necessary.
Even though I still think it is necessary, it might have been a reasonable argument if he would have acted more agreeable. But he was saying the feature was useless anyways "everyone will use relative paths only anyways" and "because noone here cares a ratass about maintaining the tests it will all fall on me again" ..
Wtf was this guys problem, I (CAPS) was going to write the stupid test and since when do we not write tests in order to better maintain our product? I get that he worries that the test environment will get more messy, but thats better than having the product code go messy or unfunctional! And c'mon guys, how are absolute paths a redundant feature...
Spent months building a full regression testing framework app at the request of my boss...
Now he just says need a simple app to test a few static URLs...
I could've written that in 1 day... FML...
And now I've been pulled away from the main thing he wanted me to work on...
and keeps asking if it's done yet...
The gap of data science in industry and academia is so large. As a data scientist in a large financial company, I see that people are still using traditional models such as linear regression and SVM, while people in academia keep inventing new concepts and techniques such as deep learning.
I am not saying that we should completely embrace deep learning, or stick to classic methods. But I just feel so surprised that the gap is so large...Sometimes I am even thinking whether I am doing the right "data science"...3
One day I'll stop creating bugs on production. I think the last 3 releases I've introduced bugs. They need to hire a tester for our team. The other two teams have dedicated testers. I suck at regression testing.3
After three months of development, my first contribution to the client is going live on their servers in less than 12 hours. And let me say, I shall never again be doing that much programming in one go, because the last week and a half has been a nightmare... Where to begin...
So last Monday, my code passed to our testing servers, for QA to review and give its seal of approval. But the server was acting up and wouldn't let us do much, giving us tons of timeouts and other errors, so we reported it to the sysadmin and had to put off the testing.
Now that's all fine and dandy, but last Wednesday we had to prepare the release for 4 days of regression testing on our staging servers, which meant that by Wednesday night the code had to be greenlight by QA. Tuesday the sysadmin was unable to check the problem on our testing servers, so we had to wait to Wednesday.
Wednesday comes along, I'm patching a couple things I saw, and around lunch time we deploy to the testing servers. I launch our fancy new Postman tests which pass in local, and I get a bunch of errors. Partially my codes fault, partially the testing env manipulating server responses and systems failing.
Fifteen minutes before I leave work on the day we have to leave everything ready to pass to staging, I find another bug, which is not really something I can ignore. My typing skills go to work as I'm hammering line after line of code out, trying to get it finished so we can deploy and test when I get home. Done just in time to catch the bus home...
So I get home. Run the tests. Still a couple failures due to the bug I tried to resolve. We ask for an extension till the following morning, thus delaying our deployment to staging. Eight hours later, at 1AM, after working a full 8 hours before, I push my code and leave it ready for deployment the following morning. Finally, everything works and we can get our code up to staging. Tests had to be modified to accommodate the shitty testing environment, but I'm happy that we're finally done there.
Staging server shits itself for half a day, so we end up doing regression tests a full day late, without a change in date for our upload to production (yay...).
We get to staging, I run my tests, all green, all working, so happy. I keep on working on other stuff, and the day that we were slated to upload to production, my coworkers find that throughout the development (which included a huge migration), code was removed which should not have. Team panics. Everyone is reviewing my commits (over a hundred commits) trying to see what we're missing that is required (especially legal requirements). Upload to production is delayed one day because of this. Ended up being one class missing, and a couple lines of code, which is my bad (but seriously, not bad considering I'm a Junior who was handed this project as his first task at his first job).
I swear to God, from here on out, one feature per branch and merge request. Never again shall I let this happen. I don't even know why it was allowed to happen, it breaks our branch policies. But ohel... I will now personally oppose crap like this too...
Now if you'll excuse me... I'm going to be highly unproductive and rest, because I might start balding otherwise after these weeks...
Everyday Build releases for closed Alpha.
My PM wants our QA to do "Little bit Smoke testing" and "little bit regression" .
i hate the QA guys when they gets excited finding a "SUPER REGRESSION OMG THE APP IS BROKEN" just to find out that they haven't read the new specifications.4
hey guys, im a total noob and new to this field. this post is open for criticism and suggestions.
so i wanna forecast slippage (dependent) using the % WT Plan (planned work, the predictor).
i get -0.35 for correlation.
and im using knn regression
how does this look to you? insights and comments are appreciated. thanks!44
Today I learned if you ack a message twice, RabbitMQ shits the bed. Dang. Another day wasted on a dumb refactoring regression.2
Something weird is happening at my company. Me and my colleague were in a team building a web application (October CMS and angular 8). I just returned from vacation and was absent for the first 2 weeks of dev. Some days in management announced that the project is "on hold", I guess something to do with paperwork, but the dev will continue. I got to work in the project only for 2 days and was shifted (with a colleague) to work on regression tests for some app I have never seen. A week or more has passed and still I have no VPN access to the app. (the app is hosted by some other company) I am bored of doing nothing. I have experienced a pattern of shifting between projects a lot. Still have not been in one from start till the very end. It is annoying. I feel that there is a lack of communication here.
Currently in our 4th cycle of manual regression testing for a release and still finding bugs. Automated tests? What are those? That sounds an awful lot like it would take time to implement. Time that could be spent fixing the bugs and getting the release out the door.
When release dates take priority over quality....
So I'm testing a co-workers code and doing regression scenarios when suddenly it "loses" data in two fields after I save the data and go out/come back into the form. That's weird says I, lets have a look....
And I find the following conditional::
if (field empty) then failValidation("hey stoopid user")
else blank field value
Happy Friyay everyone....
Updating WordPress plugins and pushing directly through Test to Live without stopping and doing regression tests on Test first. “It’s just Yoast SEO. What could go wrong?”
Who the fuck authorizes a new build to be pushed at 430pm on a friday and then demands full regression testing be done immediately regardless of how long it takes? Fucking analysts shouldn't be allowed to dictate the schedule if they don't understand the effort required behind the scenes.
99% of the time I wouldn't care but I'm the only tester with DB access and I'm supposed to go on the first date I've had in months tonight at 6.
Been stuck a week with JSON serializer struggles on the backend I'm working on... First of all, this project has source code dating back to 2013, and the dudes back then decided to use three versions of json. So you have your usual application/json and then two custom ones.
Not happy with that, they decide on using two serializers, XStream and Jackson. One custom and application/json run through XStream, and the other more legacy custom JSON runs through Jackson. So this is a bloody mess.
But now they want application/json running through Jackson, and this is breaking all the regression tests. Have to reimplement all the type, field, alias and other kinds of mappings they made for XStream, and sort out all the regressions this causes.
And the dude who designed all of this is revered in the company, although he left a while back. Not sure if I'm too much of an idiot to understand the utter brilliance of the approach, or its just poorly designed... Fuck my life, those due dates just keep creeping closer and closer and this kinda crap just keeps coming :S2
For a little background on the sort of stuff I'm dealing with, check out my last rant.
Anyways, I'm testing this pipeline at work and was just reminded of the fucktarded way a "software engineer", who had a bachelor's biology degree, decided to handle a json file.
The script is question is loading a json file containing an array of objects. The script is written in perl. There's a JSON module. Use that? Fuck no! Let's rather perform an in-place sed command on the file substituting the commas separating objects in the array with newlines, then proceed to read the file line-by-line and parse out the tokens manually. Mind you, in the process of adding the newlines he didn't keep the commas, so now all of these json files his bullshit handled are invalid json that cannot be parsed.
The dumb ass was lucky the data in the file is always output upstream as a single line and the tokens for each object are always in the same order, so that never led to problems. But now, months later after I fixed his stupidity I am being reminded of it again as I'm testing and debugging some old projects as part of regression testing new changes I'm making.
TL;DR Fuck dumbwit motherfuckers who can't even google search "parsing a json file" and doing literally anything that is less fucktarded than manually parsing a json file2
Technical lead decides to change some transitively resolved dependencies to Maven with some configurations not existing, 2 days before release to production. Thanks to our none existing regression tests, no users can log in after releasing. Guess who can fix it ASAP (of which business thinks it means, in half an hour)
A friend who just got into ML recently.
"Dude, did you know how amazing ML is??"
"I'm training a computer to give out outputs, basic AI dude"
"Dude logistic regression is the shizz"
"You heard about backprop mate?"
"ANN is the next big thing. I'm currently working on one of the biggest AI project now"
So I casually ask him whether he completely his project or not. He proudly showed me a 9 lined code he copy pasted from Google (search for neural network in 9 lines) and said, "Dude I trained my laptop with some advanced AI techniques to give out the perfect XOR outputs"
He rounded off values like 0.99 to 1 and 0.02 to 0 to make it look perfect.
Finally on github.
I use this to test the css changes to my ui.
It's still a work in progress, not even documented properly, but I'm just happy that company allowed this code to go open sourced.
So, I’m currently a software tester (please don’t hate me) who is looking to move into development. I’ve been teaching myself programming and have been applying for junior dev jobs.
But it’s been tough, places I’ve been applying for want candidates who have had at least 1 year experience developing in a previous role.
I’ve had an interview for a junior role, but they wanted someone with more experience (and it was my first technical interview so I may have made a few mistakes)
I don’t want to be testing software manually forever (seriously, the manual regression test pack where I work is 1000+ test cases), I find programming more interesting and fun.
What can I do devRant?
Onwards and upwards with the applications. 👍4
- we need to show progress to the business
- but rewriting this component to be generic AND implementing it on the whole website can't be completed in one sprint. This will require a lot of regression testing, modifications to existing functionality, etc. we need to split it in two
- that's disappointing
we were forced to write shitty patchworks for over 2 years and now everyone's surprised it takes time to replace with proper code -.-
Me: it's a regression bug, I'll update you once I've patched and deployed.
Tester: What's a regression bug?
New version, new regression tests. It's the first time I'm trying to run them fully automated. Tests were ok separately, but as it turns out, "random" generated number is not OK for creating unique names if it's being created from datetime (yymmddmmss), and tests run within one minute.
Also, new version broke our hack of disabling browser pop-up confirmations. Fuck.1
Hey rants! So I am going to test Balmer curve once again! Preparing regression model for altered SIR model with time dependent parameters (for Covid). Wish me successful code!
