Testivus On Test Coverage
Early one morning, a programmer asked the great master:
“I am ready to write some unit tests. What code coverage should I aim for?”
The great master replied:
“Don’t worry about coverage, just write some good tests.”
The programmer smiled, bowed, and left.
...
Later that day, a second programmer asked the same question.
The great master pointed at a pot of boiling water and said:
“How many grains of rice should I put in that pot?”
The programmer, looking puzzled, replied:
“How can I possibly tell you? It depends on how many people you need to feed, how hungry they are, what other food you are serving, how much rice you have available, and so on.”
“Exactly,” said the great master.
The second programmer smiled, bowed, and left.
...
Toward the end of the day, a third programmer came and asked the same question about code coverage.
“Eighty percent and no less!” Replied the master in a stern voice, pounding his fist on the table.
The third programmer smiled, bowed, and left.
...
After this last reply, a young apprentice approached the great master:
“Great master, today I overheard you answer the same question about code coverage with three different answers. Why?”
The great master stood up from his chair:
“Come get some fresh tea with me and let’s talk about it.”
After they filled their cups with smoking hot green tea, the great master began to answer:
“The first programmer is new and just getting started with testing. Right now he has a lot of code and no tests. He has a long way to go; focusing on code coverage at this time would be depressing and quite useless. He’s better off just getting used to writing and running some tests. He can worry about coverage later.”
“The second programmer, on the other hand, is quite experience both at programming and testing. When I replied by asking her how many grains of rice I should put in a pot, I helped her realize that the amount of testing necessary depends on a number of factors, and she knows those factors better than I do – it’s her code after all. There is no single, simple, answer, and she’s smart enough to handle the truth and work with that.”
“I see,” said the young apprentice, “but if there is no single simple answer, then why did you answer the third programmer ‘Eighty percent and no less’?”
The great master laughed so hard and loud that his belly, evidence that he drank more than just green tea, flopped up and down.
“The third programmer wants only simple answers – even when there are no simple answers … and then does not follow them anyway.”
The young apprentice and the grizzled great master finished drinking their tea in contemplative silence.

Attended one of the best meetups ever. To give you an idea how awesome it was..
Speaker took the first ~20 minutes introducing himself.
His intro card deck kept referring to himself in the third person (he is the only employee in consulting 'company'). Ex. "Mr. Smith began his humble career .."
The powerpoint presentation began with him clicking each page, not executing the slideshow (ex. pressing F5).
Finally someone asked "Can you make slide bigger?"
S:"You can't read that?..um..sure...I guess .."
Starts fumbling around the zoom ...
Dev: "No, can you start the slideshow?"
S: "I don't know what you mean...there...I zoomed it, is that better? Now I can't see my notes..just sec.."
<fumbles again with the zoom>
Dev: "No, not zoom, start the slide show, press F5"
S: "Oh...you want me to F5 it...OK..."
<he *clicks* the slide show button>
Finally getting into code, trying to get out of powerpoint ...
S: "How do I get out of this fullscreen?.."
Dev: "Hit escape"
S:"No..um.."
<keeps trying to click on 'something'>
S:"I see visual studio, but its not on the big screen... "
<keeps click on 'something', no one is sure whats going on>
Dev: "Hit Escape to stop the slideshow"
<finally hits escape, then able to put Visual Studio on the big screen>
S: "Ahh...there, I figured it out."
Speaker had no end of making wild/random statements like:
".Net Core is the future of Microsoft, if you're using .Net 4.5...forget it, its not even supported anymore."
"When I was at Microsoft Build, I asked them why not put all the required .Net assemblies in one directory. Looks like with .Net Core, they listened to me" (he was serious)
"I don't use SQL Server Mgmt Studio. Its free and it sucks. I use <insert a very expensive SSMS clone>, its great, you guys should check it out", then proceeds to struggle to open a query window to write some SQL.
"When you use .Net Core and EntityFramework, you have to write your own stored procedures. If a developer can't write stored procedures, he shouldn't be in this business."
I was on the edge of my seat, hungry for the next crazy bat-shit thing to come out of his mouth. He did not disappoint. BEST MEETUP EVER!9 -
This motherfucker tried to fuck me!
Ok, here's the full story.
I applied for a quick job as freelancer. He told me I just had to implement stripe payment gateway. After finishing that he asked to save the user data from payment to the database, too. I added that. All the way he wanted me to work on his ugly project on a rotten server through cpanel. But I refused instead I uploaded a showcase environment on my own server.
After he tested my code and all was working as expected he again tried to make me implement the code right away into his retarded project before payment. When I mentioned that he has to pay me first he started bitching that he won't pay in advance.
At this point I left that fucker. Knowing that my feeling was right and this bitch never had the intention to pay for my work. He just wanted to steel my code.
Fuck you. I hope you get eaten in your bed by very hungry slugs one day. Like this one guy here on devrant.19 -
I'm getting ridiculously pissed off at Intel's Management Engine (etc.), yet again. I'm learning new terrifying things it does, and about more exploits. Anything this nefarious and overreaching and untouchable is evil by its very nature.
(tl;dr at the bottom.)
I also learned that -- as I suspected -- AMD has their own version of the bloody thing. Apparently theirs is a bit less scary than Intel's since you can ostensibly disable it, but i don't believe that because spy agencies exist and people are power-hungry and corrupt as hell when they get it.
For those who don't know what the IME is, it's hardware godmode. It's a black box running obfuscated code on a coprocessor that's built into Intel cpus (all Intell cpus from 2008 on). It runs code continuously, even when the system is in S3 mode or powered off. As long as the psu is supplying current, it's running. It has its own mac and IP address, transmits out-of-band (so the OS can't see its traffic), some chips can even communicate via 3g, and it can accept remote commands, too. It has complete and unfettered access to everything, completely invisible to the OS. It can turn your computer on or off, use all hardware, access and change all data in ram and storage, etc. And all of this is completely transparent: when the IME interrupts, the cpu stores its state, pauses, runs the SMM (system management mode) code, restores the state, and resumes normal operation. Its memory always returns 0xff when read by the os, and all writes fail. So everything about it is completely hidden from the OS, though the OS can trigger the IME/SMM to run various functions through interrupts, too. But this system is also required for the CPU to even function, so killing it bricks your CPU. Which, ofc, you can do via exploits. Or install ring-2 keyloggers. or do fucking anything else you want to.
tl;dr IME is a hardware godmode, and if someone compromises this (and there have been many exploits), their code runs at ring-2 permissions (above kernel (0), above hypervisor (-1)). They can do anything and everything on/to your system, completely invisibly, and can even install persistent malware that lives inside your bloody cpu. And guess who has keys for this? Go on, guess. you're probably right. Are they completely trustworthy? No? You're probably right again.
There is absolutely no reason for this sort of thing to exist, and its existence can only makes things worse. It enables spying of literally all kinds, it enables cpu-resident malware, bricking your physical cpu, reading/modifying anything anywhere, taking control of your hardware, etc. Literal godmode. and some of it cannot be patched, meaning more than a few exploits require replacing your cpu to protect against.
And why does this exist?
Ostensibly to allow sysadmins to remote-manage fleets of computers, which it does. But it allows fucking everything else, too. and keys to it exist. and people are absolutely not trustworthy. especially those in power -- who are most likely to have access to said keys.
The only reason this exists is because fucking power-hungry doucherockets exist.26 -
that moment when you start to code at 9am and you are starting to get hungry so you check the clock 15 minuts later and it is already 5pm6

My Perfect Day : Assumption
Woke up at 6. Went for morning walk or do yoga or some sort of stuff.
Came back at 7. Went for daily routine, like bathing and all.
Went to prepare breakfast at 7:45. Prepared some eggs and bread and coffee.
It is 8:15 now. Reading news papers or watching tv and doing breakfast.
At 9 check mails and prepare some stuff.
At 9: 30 went for office. Reached office 5 minute before 10, safe and sound.
Came back at 7 by evening. Did some rest. Prepare dine till 9. Take a bath. Complete the dine.
At 10:30 ready to sleep.
Actual Scenario :
Woke up at 8:30. No time for yoga or morning walk. No time for preparing breakfast as well. Went straight to bathroom. Came back in 20 minutes. Made a cup of coffee. No time for newspaper or tv.
Feeling lazy and tired already. At 9:10 went for office. Before reaching office stopped at fast food joints. buy some junk food. Eat them. Got traffic jam and reached office late.
Started working but feeling lazy. Boss asked twice about the project status and i am unable to think a single line of code.
However, days passed. Boss scolded me. I promised him to finish the work after reaching home.
Reached home at 7:30. Late for no reason. Went straight to bed. Sleeps a hour. But took 20 minutes to leave bed.
Started working on projects i did not complete in the office.
Time fly and it is already 1 in morning. No dinner. Tired as fuck but hungry as well. So made some eggs and eat. Wrapped the task but it is 3:30 in morning and i jumped to bed for sleep.

Writing bad code has its perks.
Whenever you are hungry you only have to write a few lines of code and you get some spaghetti3 -
Third call of the morning. No one I need is answering. Boss fell asleep (but went on mute, thankfully) and deputy director is on the line listening in.
I'm hungry. Cranky. And feeling ignored.
To all my dev friends here: please answer your phones of you're needed to give information about your code. These are code specific issues (ie- application/program specific) that require knowing the code to know what broke so we know how to fix it.10 -
Consumers ruined software development and we the developers have little to no chance of changing it.
Recently I read a great blog post by someone called Nikita, the blog post talks mostly about the lack of efficiency and waste of resources modern software has and even tho I agree with the sentiment I don't agree with some things.
First of all the way the author compares software engineering to mechanical, civil and aeroespacial engineering is flawed, why? Because they all directly impact the average consumer more than laggy chrome.
Do you know why car engines have reached such high efficiency numbers? Gas prices keep increasing, why is building a skyscraper better, cheaper and safer than before? Consumers want cheaper and safer buildings, why are airplanes so carefully engineered? Consumers want safer and cheaper flights.
Wanna know what the average software consumer wants? Shiny "beautiful" software that is either dirt ship or free and does what it needs to. The difference between our end product is that average consumers DON'T see the end product, they just experience the light, intuitive experience we are demanded to provide! It's not for nothing that the stereotype of "wizard" still exists, for the average folk magic and electricity makes their devices function and we are to blame, we did our jobs TOO well!
Don't get me wrong, I am about to become a software engineer and efficient, elegant, quality code is the second best eye candy next to a 21yo LA model. BUT dirt cheap software doesn't mean quality software, software developed in a hurry is not quality software and that's what douchebag bosses and consumers demand! They want it cheap, they want it shiny and they wanted it yesterday!
Just look at where the actual effort is going, devs focus on delivering half baked solutions on time just to "harden" the software later and I don't blame them, complete, quality, efficient solutions take time and effort and that costs money, money companies and users don't want to invest most of the time. Who gets to worry about efficiency and ms speed gains? Big ass companies where every second counts because it directly affects their bottom line.
People don't give a shit and it sucks but they forfeit the right to complain the moment they start screaming about the buttons not glaring when hovered upon rather than the 60sec bootup, actual efforts to make quality software are made on people's own time or time critical projects.
You put up a nice example with the python tweet snippet, you have a python script that runs everyday and takes 1.6 seconds, what if I told you I'll pay you 50 cents for you to translate it to Rust and it takes you 6 hours or better what if you do it for free?
The answer to that sort of questions is given every day when "enganeers" across the lake claim to make you an Uber app for 100 bucks in 5 days, people just don't care, we do and that's why developers often end up with the fancy stuff and creating startups from the ground up, they put in the effort and they are compensated for it.
I agree things will get better, things are getting better and we are working to make programs and systems more efficient (specially in the Open Source community or high end Tech companies) but unless consumers and university teachers change their mindset not much can be done about the regular folk.
For now my mother doesn't care if her Android phone takes too much time to turn on as long as it runs Candy Crush just fine. On my part I'll keep programming the best I can, optimizing the best I can for my own projects and others because that's just how I roll, but if I'm hungry I won't hesitate to give you the performance you pay for.

No work experience: I'm gonna be the best programmer in the world. My code is beautiful. This is my passion.
After 1-2 years experience: just f@#$!ng work pls so i can go home goddamit i hate my life im hungry f@$!% everyone.4 -
I have already done like 3 internships of 6 months now. And all the companies sucked!
Now the current company I work at is at least not a marketing company filled with cocaïne sniffing callcenter junkies. But why do they always lie so much. They promised free food and drinks and code reviews. What I get is a computer with an i5 and a fucking Jira account.
This is fucking annoying me, im hungry, thirsty and somebody should really check the code im about to push because it cant be good!!!3 -
Hey Code-tards,
We're announcing a new update to our software `FUCK YOU` to include a new 'feature' no one asked and would give a FLYING FUCK about, but we were sitting on our MOTHERFUCKING ASSES and had to justify our salaries somehow.
So this new feature really just makes your life horrible by taking away or breaking all useful features you were PERFECTLY HAPPY with before, but FUCK YOU if you aren't happy with it and don't throw half of your salary our way every month.
Remember our library you were perfectly OK with, that u integrated in your codebase? DEPRECATED from this second onwards. WHY? BECAUSE FUCK YOU ! That's WHY.
Oh yeah, and one last thing before we make your life a living hellhole, give us your SSN, credit card(s) and mortgage payments to us, you money-hungry CUNT. Haven't you heard the phrase already? YOU WILL OWN NOTHING AND YOU WILL BE HAPPY.2 -
How surprising is it when a person designs code in a very clear and impressive structure and just when you think about asking them for guidance, they reveal themselves to be complete turds?
I've been working with this person's "infra" code, at work. I've rewritten some classes to use their infra. I had a vague idea of how the classes work. I had no idea of how their code works. Expectedly, there were some issues but now only minor ones remain.
I asked them for a description of what I'm supposed to do for the few bugs I'm facing. They replied in such a condescending tone, it made me want to punch them through the screen.
Almost a month later, we're still going back and forth with emails. I've been swallowing it and responding calmly. I never got direct answers. Always deflections to irrelevant things or veiled insults. I took it because they did correct one silly error of mine that actually my code reviewer should've caught. (What's worse is that it got introduced by me just before my review and commit.)
But does that give them the right to insult me in front of the whole team including my project manager? I got a reply today from them with everyone of note in cc implying very clearly that I have not done any work. They highlighted a line from my code with some todo tag (that was not meant for them) to make their invalid point. A line that's unrelated to the bug I asked them about. This is after I proved them wrong when they insisted that I had done something wrong about a feature related to the bug.
If you don't understand what I asked for fucking ask me to ask again. But do not fucking try establish yourself on higher ground by pointing out irrelevant things in my code.
I was shocked and enraged that they'd do such a thing. I double checked everything like a mad man. Despite knowing that the fix has to come from them, I was instantly transported to the noob stage, grasping at straws. I wanted to send a really scathing reply right away but my manager asked me to wait.
My mind is now a see saw shifting between a panicked noob questioning every fucking thing I ever did in my nada life and a hungry enraged monster looking to maul that fucking shithead for burning me like that.1 -
!dev, !rant
Was thinking about the things I miss thanks to the 'rona whilst coding. Restaurants are a big one (I haven't had an oyster in a dog's age). We've lost a ton of businesses recently, most of which will never be back. As much as I Uber eats and doordash, restaurants lose money on those mechanisms frequently due to the up to 30% order commission.
There's definitely a potential market for an epic games-store style player in that segment who wants to compete on cost and fees. Hard part would be the political weight that's coming down on those businesses now. It's a really shitty time to be in most businesses.
Tl;Dr There will never be a better name for a donut shop than "Hole Foods." RIP2 -
Rant rant rant!
Le me subscribe to website to buy something.
Le register, email arrives immediately.
*please not my password as clear text, please not my password as clear text *
Dear customer your password is: ***
You dense motherfucker, you special bread of idiotic asshole its frigging 2017 and you send your customer password in an email!???
They frigging even have a nice banner in their website stating that they protect their customer with 128bit cryptography (sigh)
Protect me from your brain the size of a dried pea.
Le me calm down, search for a way to delete his profile. Nope no way.
Search for another shop that sells the good, nope.
Try to change my info: nope you can only change your gender...
Get mad, modify the html and send a tampered form: it submits... And fail because of a calculation on my fiscal code.
I wanna die, raise as a zombie find the developers of that website kill them and then discard their heads because not even an hungry zombie would use that brains for something.1 -
I thought iPhone simulator was ONE THING that worked smoothly but NO, it is also a load of crap, hogging away the memory. Can’t develop ANYTHING without spoiling the mood because of this slow performance. It’s the same with android studio, Xcode, android emulators, and now simulator with vscode is doing the same thing. It’s 2020 you’d think a developer can write code smoothly on a huge MacBook Pro but no what a fucked up world, I’m hungry again, I have eaten up everything what to do I hate fruits !!7

Finished exams, in 3 days i have a flight to my parents house to see them.
Before that, thought about comming to my grandma's home, which has a beach nearby so i can spend 1-2 days relaxing.
Came here. No one is home. I don't have keys either. I'm hungry too.
Fortunately the wifi signal is ok.
Sat in front of the door, and opened my laptop.
Time to start migrating my projects from duck to static typing and practising my ability to write python code with type annotations until someone comes home.3 -
I don't get publicity hungry personalities on Medium. Their usual headlines :

Play Store's $25 registration fee - for getting PWA listed in their shitty catalogue? Who in the right mind would even jump in this clusterfuck of store to find a *web* app? For all you know, Google, there is such thing as QR codes - and customers can just scan the code (or type in that sweet address). Voila! Boom!!! Ching-ching!
Hello-hello, monopolistic cashgrabage! I came to inform you that your TWA bullshit is unneeded in ETHICAL space. The only ones who would benefit from this thing are permission-hungry publishers. And I'm already sick of this culture where people are put into store bubbles. You can't hide the fact that this data and features you provide, with "native" layer, may be misused in a jiffy - and by big players, no less. Of course, as a vile dumpster that you are, you don't mind it.
Don't even bring up a battery consumption that comes with PWA and browser. This doesn't matter if you use an app for some 2 minutes to tick your mental checkboxes! I'm just sick of app stores and native apps that collect the data without normal warning, and dare to take more than 1 second to fucking load the cached data. Take a lesson or two from PWAs that collect (probably useful) cache, instead of my specs, and load almost instantly.12 -
Shit, I lost the rant again. Well let's begin from the top.
This is little bit personal but I'm not keeping any of this as a secret. I'm a hyperactive thinker at nights (ADHD). I must write this down, although it's well over middle-night at this point.
I just discovered that I might be better writer whilst I'm sleepy, hungry, out of affection of the meds or all of the above.
And may I remind you that I'm not a native English speaker or writer.
* Saved to clipboard, so I won't lose this again *
I've written now 2 long rants, 8 issue reports (devRant) and a loong collab posting in this one sitting, or rather laying. It feels like I'm writing perfectly without missing a beat. I know that's not right, it's the main symptom in ADHD; My brain is actually running slower than an average, much slower. That's a reasonable explanation for the “fast” innovation.
I'm running without restrictions of a normal human, I don't "overthink" every single word and rather go with the flow. That's what spell checkers are for.
* Save *
You can probably see what's happening. It's certainly also true when writing code. I left out the normal cleaning up (except for the grammar, found 10 errors).
It's pretty much the same thing as I'd imagine being drunk or even high.
I must not be the only one.

everytime i see posts of code humor of doing ordinary things (for example while hungry eat) i wished i was dead.
they are too lazy and beginner. and they exist because the internet gives everyone some chance of exposure.
while this may seem like a positive and democratic thing, it results in too much low quality and everyone's standards getting lowered.
i don't mind people telling bad jokes to friends and family, because at least then even though sometimes people laugh, a frown will surely happen.
while in the internet, you don't get that reaction. In fact, the shittier the thing you post, the more points you get!
this is my version expressing how i feel about the matter:
while !is_dead()
eat_excrement_from(corpse)
bile_and_shit = vomit()
eat(bile_and_shit)
while it is true that most things online are garbage, that also means that some isn't.
for example, code-poetry.com has very clever code poems that actually does run and has some interesting STDOUT. and those do are worthwhile.
let me also do a preemptive comment to the first fucking idiot that posts a "you must be fun at parties". fuck parties and fuck you too.1 -
unlimited time is not the only problem. During that time I'd get hungry, cold and tired -- I need to afford to buy food, have a home with roof and warmth. So with unlimited time, I'll also need unlimited funds.
And if I had unlimited funds I'd spend most of my time AFK: buying a house, making it pretty, setting up my own lab and a solar+wind powerplant, recruiting some folks to finish my project for me. Then travel all around the world, while my code monkeys are busy making me famous for introducing new tech to the world - so new, that it'll change the way we live, that it'll change our communication, interaction and other habits. And then I'll be ready for the EternalLife underground project, where another set of teams of bio-monkeys will be busy making my consciousness alive after my body wears out.
If only I had all those funds...
Care to chip in? -
I never thought in my life that I would say this sentence one day - but:
Today I switched back to VS Code because it uses less memory than IntelliJ.
Context: Only temporary, very resource hungry dev environment, TypeScript, IntelliJ used >4.5 GB of ram and started lagging.5 -
It took me 48 hours ( not continuously) to fix a bug by going through a cluster fuck code of multiple modules. Tracing the error through 5 or 6 layers. And u dont get error logs right away. You need to recreate that error and see the logs on a kubernetes pod. Just to find out the bug was a duplicate.
Yes jokes are on me. I fucked up by not checking for duplicate. I steered right away on that shit dipped bug like a hungry/zombie hound. Fuck me. -
Okay, so not eating has become a major problem now. This morning when i got out of bed and stood up, i fell backwards in to my bed again. I couldn't see anything, all black. A few minutes went past and i got back on my feet, got dressed and headed to school.
The thing is, a day can go past and i won't feel hungry at all. But i have to eat, but i don't.
Am i the only one with this problem?
Another thing that is happening is that when i get home from school i sit down in front of my computer and start to write some code, hours fly by and there goes that day, no homework done either.
No food, no homework. Only coding. I think i have a serious problem 😂.
On a side note, a few days ago i tasted coffee for the first time, and now i can't resist buying a cappuccino/latte when i walk past espresso house in the morning.
Here's a interesting question, why the fuck did you waste your time reading this? 😂1
