First time spending my lunch break outside this year. Didn't realize how much I missed it. It really helps to breath some fresh air when you got a bad day in office. How do you guys normally spend you lunch break?

My two cent: Java is fucking terrible for computer science. Why the fuck would you teach somebody such a verbose language with so many unwritten rules?

If you really want your students to learn about computer, why not C? Java has no pointer, no passed by reference, no memory management, a lots of obscure classes structure and design pattern, this shit is garbage. The student will almost never has contact with the compiler, many don't even know of existence of a compiler.

Java is so enterprise focused and just fucked up for educating purpose. And I say it as somebody who (still) uses it as main language.

If you want your students to be productive and learn about software engineering, why not Python? Things are simple in Python can can be done way easier without students becoming code monkeys (assuming they don't use for each task a whole library). I mean java takes who god damn class and an explicitly declared entry point which is btw. fucking verbose to print something into the console.

Fuck Java.

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.

Wipe windows in seconds with Linux😂😂

Interesting bug hunt!

Got called in because a co-team had a strange bug and couldn't make sense of it. After a compiler update, things had stopped working.

They had already hunted down the bug to something equivalent to the screenshot and put a breakpoint on the if-statement. The memory window showed the memory content, and it was indeed 42. However, the debugger would still jump over do_stuff(), both in single step and when setting a breakpoint on the function call. Very unusual, but the rest worked.

Looking closer, I noticed that the pointer's content was an odd number, but was supposed to be of type uint32_t *. So I dug out the controller's manual and looked up the instruction set what it would do with a 32 bit load from an unaligned address: the most braindead thing possible, it would just ignore the lowest two address bits. So the actual load happened from a different address, that's why the comparison failed.

I think the debugger fetched the memory content bytewise because that would work for any kind of data structure with only one code path, that's how it bypassed the alignment issue. Nice pitfall!

Investigating further why the pointer was off, it turned out that it pointed into an underlying array of type char. The offset into the array was correctly divisible by 4, but the beginning had no alignment, and a char array doesn't need one. I checked the mapfiles and indeed, the old compiler had put the array to a 4 byte boundary and the new one didn't.

Sure enough, after giving the array a 4 byte alignment directive, the code worked as intended.

When searching for internship via school I found this small startup with this cute project of building a teaching tool for programming. There were back then 2 programmers: the founder and the co-founder.

Then like 1 week before the internship started, the co-founder had a burnout and had to get off the project, while the company was so low on budget the founder, aka my new b0ss, had to work separate jobs to keep the company alive. (quite metal tbh)

It's funny because I'm a junior developer, 100%. I've been coding as a hobby for around 8 years now but I've never worked in a big company before. (No exception to this workplace either)

First project I get: rewrite the compiler. The Python compiler.
"But wait, why not just embed a real compiler from the first case?"
-nanananana it's never simple, as you probably know from your own projects.

The new compiler, as compared to existing embedded compiler solutions out there, needed these prime features:
- Walk through the code (debugger style), but programmatically.
- Show custom exceptions (ex: "A colon is needed at the end of an if-statement" instead of "Syntax error line 3")
- Have a "Did-you-mean this variable?" error for usage of unassigned variables.
- Be able to be embedded in Unity's WebGL build target

All for the use case of being a friendly compiler.
The last dash in the list is actually the biggest bottleneck which excluded all existing open-source projects (i could find). Compliant with WebAssembly I can't use threads among other things, IL2CPP has lots of restrictions, Unity has some as well...

Oh and it should of course be built using test-driven development.

"Good luck!" - said the founder, first day of work as she then traveled to USA for **3 weeks**, leaving me solo with the to-be-made codebase and humongous list of requirements.

---

I just finished the 6th week of internship, boss has been at "HQ" for 3 weeks now, and I just hit the biggest milestone yet for this project.

Yes I've been succeeding! This project has gone so well, and I'm surprising myself how much code I've been pumping out during these weeks.

I'm up now at almost 40'000 lines of source and 30'000 lines of code. ‼
( Biggest project I've ever worked on previously was at 8'000 lines of code )

The milestone (that I finished today) was for loops! As been trying to showcase in the GIF.

---

It's such a giant project and I can honestly say I've done some good work here. Self-five. Over-performing is a thing.

The things that makes me shiver though is that most that use this application will never know the intricates of it's insides, and the brain work put into it.

The project is probably over-engineered. A lot. Having a home-made compiler gives us a lot of flexibility for our product as we're trying to make more of a "pedagogic IDE". But no matter that I reinvented the wheel for the 105Gth time, it's still the most fun I've had with a project to date.

---

Also btw if anyone wants to see source code, please give me good reasons as I'm actively trying to convince my boss to make the compiler open-source.

Cheers!

so if guys read my prev rants... this is it im quitting my job got a better offer coz my current company blocked devrant started last week i was like wtf 1st thing that my future employer asked me what will make you happy i said "dont block sites that are helpful for devs" he lol'ed so hard btw just got it today thank you so much devrant my macbook and laptop will now look really cool

Sales employee Bob wants a clickable blue button.

Bob tells product owner Karen about his unstoppable desire for clickable blue buttons.

Karen assigns points for potential and impact (how much does a blue button improve Bob's life, how many people like Bob desire blue buttons)

Karen asks the button team how hard it is to build a button. The button team compares the request to a reference button they've built before, and gives an ease score, with higher score being easier (inverse of scrum points).

These three scores are combined to give a priority score. The global buttonbacklog is sorted by priority.

Once every two weeks (a "sprint") the button team convenes, uses the ease scores to assign scrum points. Difficult tasks are broken up into smaller tasks, because there is a scrum point upper limit. They use the average of the last 5 sprints to calculate each developer's "velocity".

The sprint is filled with tasks, from the top of the global button backlog, up to the team's capacity as determined by velocity. Approximate due dates are assigned, Bob is a happy Bob.

What if boss Peter runs into the office screaming "OUR IMPORTANT CLIENT WANTS A FUCKING PINK BUTTON WHICH MAKES HEARTS APPEAR"?

Devs tell boss to shut the fuck up and talk to Karen. Karen has a carefully curated list of button building tasks sorted by priority, can sedate boss with valium so he calms the fuck down until he can make a case for the impact and potential of his pink button.

Karen might agree that Peter's pink button gets a higher priority than Bob's blue button.

But devs are nocturnal creatures, easily disturbed when approached by humans, their natural rhythms thrown out of balance.

So the sprint is "locked", and Peter's pink button appears at the top of the global backlog, from where it flows into the next sprint.

On rare occasions a sprint is broken open, for example when Karen realizes that all of the end users will commit suicide if they don't have a pink heart-spawning button.

In such an event, Peter must make Bob happy (because Bob is crying that his blue button is delayed). And Peter must make the button team of devs happy.

This usually leads to a ritual involving chocolate or even hardware gift certificates to restore balance to the dev ecosystem.

Keyboards (like mine at work) that have play/pause, mute, volume up, volume down, but no next track or previous track are the absolute worst, like what the fuck.

Instead its got a fucking button for calculator, email and a home button.

"How useful was your CS degree and why?" - I studied CS at university, my education always was incredibly useful.

Firstly, the knowledge you gain in itself is useful. Furthermore, we explain and understand the unknown in terms of the known. Thus, the more you know, the easier you learn new things.

But secondly and more importantly, university teaches you *how* to think. In a structured way, like a scientist or engineer. To see the bigger picture.

I originally wanted to end here, but I've read a couple of entries doubting the usefulness of any CS degree.

Our profession isn't all that different from others. It is, however, relatively young. How's this for an analogy: We're still in the stage of building sand castles. That's fine, and can be self taught. But in years to come we'll want to build bridges and sky scrapers, which are not just "sand castles scaled up". Our sand castle knowledge won't help us here. Sky scrapers need entirely different materials and a good understanding of architectural statics.

Can you still teach that yourself? Maybe. Will a formal education with a degree be useful and generally more trusted? I bet.

Anyone else who tend to click on the link below instead of the one above?

Not CS degree, but EE, and totally worth the effort. Not only that without degree, I wouldn't get jobs in many companies, but I actually learnt a lot. Laplace and Fourier will be as valid in a 100 years as they were 200 years ago.

Yeah, it was fucking hard. Math was rather OK, only 50% of the students failed the first exam. EE was harder, 90% failed at the first try. That wasn't regarded as problem - on the contrary, the exams were designed to weed out. After two semesters, we already had 50% student loss.

I remember what the EE prof told us in the first semester: we would learn a lot of things, but most importantly, to think like an engineer. Didn't make sense right away, but 5 years later, I knew what he had been talking about.

!rant
I think that more than learning about CS, I learned how to cope with enormous amounts of frustration that comes with being a dev and I also felt great when I was being challenged with actual deadlines through exams, hackathons, assignments, practicals and tough professors.
Professionally, I think the great knowledge of fundamentals of CS helps a lot and it is just a great way to get your foot inside the door (for internship interviews and career opportunities) of a company and then show what you're made of when it comes to being a dev.
Also, I had the time of my life because I was around like-minded people who loved the same things and it was good to watch them suffer at first and then, watch them succeed at something that I was about to do.

Sleeping bundle of joy.

I believe it is really useful because all of the elements of discipline and perseverance that are required to be effective in the workforce will be tested in one way or another by a higher learning institution. Getting my degree made me little more tolerant of other people and the idea of working with others, it also exposed me to a lot of topics that I was otherwise uninterested and ended up loving. For example, prior to going into uni I was a firm believer that I could and was going to learn all regarding web dev by maaaaaself without the need of a school. I wasn't wrong. And most of you wouldn't be wrong. Buuuuuut what I didn't know is how interesting compiler design was, how systems level development was etc etc. School exposed me to many topics that would have taken me time to get to them otherwise and not just on CS, but on many other fields.

I honestly believe that deciding to NOT go to school and perpetuating the idea that school is not needed in the field of software development ultimately harms our field by making it look like a trade.

Pffft you don't need to pay Johnny his $50dllrs an hour rate! They don't need school to learn that shit! Anyone can do it give him 9.50 and call it a day!<------- that is shit i have heard before.

I also believe that it is funny that people tend to believe that the idea of self learning will put you above and beyond a graduate as if the notion of self learning was sort of a mutually exclusive deal. I mean, congrats on learning about if statements man! I had to spend time out of class self learning discrete math and relearning everything regarding calculus and literally every math topic under the sun(my CS degree was very math oriented) while simultaneously applying those concepts in mathematica, r, python ,Java and cpp as well as making sure our shit lil OS emulation(in C why thank you) worked! Oh and what's that? We have that for next week?

Mind you, I did this while I was already being employed as a web and mobile developer.

Which btw, make sure you don't go to a shit school. ;) it does help in regards to learning the goood shit.

Ngl I probably never would've learned any programming properly without it. I'm too disorganized and get distracted easily so I probably wouldn't have learned any language if it took me more than 30 minutes to get up and running. Plus I made great friends that I wouldn't trade for the world and learned a lot about myself and how I think and work with problems. I really doubt I would've become a hobby programmer so yeah. Unpopular opinion but I'm having a good time at uni. It also seems like my university does a lot more to prepare us for development in the real world than many other universities do so that might have something to do with it.

I found university very worthwhile, mainly for what it exposed me to that I wouldn’t have necessarily learned otherwise. University exposed me to a lot of knowledge which allowed me to discover the fields and concepts that really interested me. It also forced me to learn math, and I’ve come to really love mathematics, even though my knowledge is still not that deep. I really respect and appreciate math now that I have more than a superficial understanding of it.

CS-wise, the things that have been most useful in practice have been complexity, data structures, concurrency, and others, but complexity is probably the absolute most important thing to at least learn the basics of.

I would not say that university is a necessity though. You can absolutely get by teaching yourself, especially if you are disciplined/interested enough to keep doing it. The important thing is to learn *what* to learn.

I think the advantage of CS is that it forces you to explore things you might not think interest you, it also gives a general base and vocabulary to speak "the language" of this career. With that said I often look to hire people without CS degrees but that has the motivation to learn by themselves (I'm self-taught). The degree doesn't say much about, but if during it you explore, stay curious, look beyond 20y/o outdated advice from some professors you'd get the most out of it.

Start making a portfolio even before starting college and stay curious!

Okay so my weekend project went well :D put my retropie system inside of this old r2d2 I've had collecting dust. Has a cooling fan inside as well as a 16x2 lcd I was playing with. Got a red led tied to the rpis txd pin, ports in the front for easy access and power cord and hdmi coming out the back.

Thought of this but no one would truly get it anywhere else...

Family myFamily = new Family();
myFamily.add("husband", "Sept 2011");
myFamily.add("wife", "Sept 2011");
myFamily.add("cat", "July 2012");
myFamily.add("child", "August 2019");

Closing up the weekend!

I go to unlock my car, but the button I usually use is gone. Instead now it unlocks by long-pressing the car handle.

Ok, got it.

Then my ignition isn't there? Oh, it's in the middle of the steering wheel now? Ok.. but it doesn't work? Oh I have to sign in with Google or Facebook, alright...

Wait, where's my odometer? Oh this is "card" view, and I guess I want "compact" view, huh. Is there a dark theme? Guess not.

Why can't I shift? Oh the stick is a hamburger button now, weird. Um, and reverse is in a sub-menu? That's going to get annoying.

Alright just need to look in the mirror to see if.. wtf? You call this "responsive" or something? I can't see out that tiny window.

I'm very disappointed in all this, I wonder if I can roll back. Oh WHERE ARE THE BRAKES OH GOD

UX DESIGNERS

WHY DID WE TRUST THEM AND THEIR GODFORSAKEN UPDATES

Made it!!! Starting at CERN on September 1st! :)

A big thank you to you guys for the support in my previous posts!

1. The quality of the coffee and toilet paper you encounter during an interview tells you more than promises about table tennis or fruit baskets.

2. Try to determine who their primary client is: subscribers, app buyers, advertisers, etc. It's a major influence on the company dynamic.

3. Before an interview, you can just say: "I would like to sit down with a PO and run through one backlog feature and one bug, to get a feel for the type of tasks at the company". Such an activity immediately reveals team structure, whether they have product owners & scrum masters, what a sprint looks like, how they prioritize tasks, and how organized/chaotic your work experience will be.

If I do a job in 30 minutes it’s because I spent 10 years learning how to do that in 30 minutes. You owe me for the years, not the minutes.

It's been a long time since I last posted, I saw it as a good thing - I hadn't had stuff to complain about.

Until my fucking idiot mush-for-brains asswipe roommate locked me out of my own apartment!
Fucker is squatting with me, and while I'm away for work, decides it would be a great idea to change the locks and conveniently forget to mention it.

It's taking a lot of energy not kicking him out.

Truth:
Windows updates have nevah annoyed me !
And
My computer never restarted by itself while i am working!

Is it because i am lucky or you guys dnt know update setting exists?
