I've got a mini stroke today. My project ended and I got delegated elsewhere.
"It's going to be fine, it's c++, you will find yourself there"
Suspicious, it's a project everybody was staying out of as hard as they can. But hey, it's cool, how bad can it be? what can go wrong with that?
Reality was brutal, project that uses Boost C++ as framework and bjam as builder. Builds with a decent dose of luck, and only under special circumstances, only under one specific version of compiler. No docs, quartet of the code is in Fortran, just to use ancient lisp part which was second qarter. The most senior Dev around does not have idea how it all works. Also everything is inside one enormous try/catch block. Because of the reasons.
That's how people end up with severe alcoholism and meth addiction.8 -
Yet another rant about crappy electronic designs.
Just now I was cleaning my desk and stumbled upon some old hard drive in a caddy that I still had laying around.. I figured, let's plug it in and see whether the drive still works. And to some extent, it does! Except that every few minutes it craps out on me. And after disassembling the caddy, I think that I know why.
Just as background information, hard drives work at 12V and generally require about 10W to spin their motor. Meanwhile USB operates at 5V. So a boost converter needs to be present in the controller to step up the voltage and power the drive.
Now what's a boost converter? It's an inductor, a capacitor, a transistor and a diode in a specific arrangement (if you're interested in the design, check out https://youtube.com/watch/...), along with feedback circuitry to stabilize output voltage. Now that transistor is important.. it switches at very high frequency, and its rise and fall times create heat. In the particular transistor used in that controller, it apparently causes the transistor to operate at 65-68°C. That's quite toasty IMO, and overheating may be why the controller is so unstable. But the Chinese manufacturers thought that it's just fine and okay to be sold without heatsink or some research into transistors with better rise and fall times.
So the hard drive craps out on me and yet again it's because of certified shitdesigns. MOTHERFUCKTURERS!!!!27 -
As a consultant, you get tasked with a variety of stuff. Last few weeks been struggling to maintain an old C++ application that was written by a complete tool of an a$$hole with zero knowledge on how to write maintainable and production quality code. It would hardly run without a crash. First it was a challenge I had to accept, but as I stabilized the code and just fell over even more traps, I had to admit defeat and review my approach.
Rewrite is something I would choose last, but this one ticked all the marks worthy of a rewrite. So, the customer is a very friendly researcher and gladly spent 15 hours with me explaining all the math and concepts - just a delight for a programmer to have such a customer. Two days in, with a DDD approach - a functional, more precise, faster and stable application.
Sometimes there is no rant to share, it's rare to have that perfect communication with a customer that is so dedicated that he spends so much time teaching you his speciality and actually understand your approach. DDD was really a lifesaver here, by using it's key concepts and ubiquitous language. The program is essentially 8000 lines of math, but wrapping it up with value objects and strong domain models made me understand his domain and him mine. It also allowed me to parallelize the computations, giving me a huge performance boost. Textbook approach, there will not be many like this!4 -
I've been using microsoft dev stack for as long as i remember. Since I picked up C#/.NET in 2002 I haven't looked back. I got spoiled by things like type safety, generics, LINQ and its functional twist on C#, await/async, and Visual Studio, the best IDE one could ask for.
Over the past few years though, I've seen the rise of many competing open source stacks that get many things right, e.g. command line tooling, package management, CI, CD, containerization, and Linux friendliness. In general many of those frameworks are more Mac friendly than Windows. Microsoft started sobering up to this fact and started open sourcing its frameworks and tools, and generally being more Mac/Linux friendly, but I think that, first, it's a bit too late, and second, it's not mature yet; not even comparable to what you get on VS + Windows.
More recently I switched jobs and I'm mainly using Mac, Python, and some Java. I've also used node in a couple of small projects. My feeling: even though I may be resisting change, I genuinely feel that C# is a better designed language than Java, and I feel that static type languages are far superior to dynamic ones, especially on large projects with large number of developers. I get that dynamic languages gives you a productivity boost, and they make you feel liberated, but most of the time I feel that this productivity is lost when you have to compensate for type safety with more unit tests that would not be necessary in a static type language, also you tend to get subtle bugs that are only manifested at runtime.
So I'm really torn: enjoy world class development platform and language, but sacrifice large ecosystem of open source tools and practices that get the devops culture; or be content with less polished frameworks/languages but much larger community that gets how apps should be built, deployed, monitored, etc.
Damn you Microsoft for coming late to the open source party.11 -
Here's one that involves Windows, Linux (at the same time!), WInZip, Python, Lua and Minecraft, sort of.
So, when I get depressed I often find that old 2011 Minecraft videos help a lot from the nostalgia boost. If its stupid, but it works, it isn't stupid. Anyways, I was thinking about how much fun it must have been to just fuck around with code and make something like Minecraft. Naturally, I got a huge code boner and really wanted to do something I hadn't in a while: binding c to a higher level language.
This time around, I wanted to try Python. C + Python seems like a good pair. I watched a tutorial and it seemed pretty interesting and simple enough but I remembered that I actually like Lua a lot better than Python, so I went to the download page of Lua.
The download is a tar.gz so I let out a sigh and start typing "WinZip" into google. But no, fuck that, I hate 3rd party decompression programs on Windows. They all just give me this eerie feeling.
"This would be so much fucking easier on Linux"...
I remember that I haven't tried the Windows Subsystem for Linux. I guess it's time, isn't it?
I read the docs of how to do it. Nice little touch, they tell you how to enable WSL from PowerShell but don't mention the GUI way to do it. It's genuinely a nice touch.
So I get everything installed and go to the app store to choose a distro. I want Ubuntu. I click the Install button...
...
... "Something unexpected happened"
Windows and their fucking useless error messages. Jesus, okay. I restart computer. Same issue. I update Windows. Same thing. Uninstall WSL. Reboot. Install WSL. Reboot. Same thing. HOLY SHIT.
Went to bed. Woke up. Tried to install Ubuntu.
"Yea ok lul i'll work this time for no reason"
Finally unzipped Lua.4 -
Linus Torvalds on C++
“C++ leads to really really bad design choices. You invariably start using
the nice library features of the language like STL and Boost and other total and utter crap, that may help you program, but causes:
- infinite amounts of pain when they don't work (and anybody who tells me
that STL and especially Boost are stable and portable is just so full of BS that it's not even funny)
- inefficient abstracted programming models where two years down the road you notice that some abstraction wasn't very efficient, but now all your code depends on all the nice object models around it, and you cannot fix it without rewriting your app.”

How I got selected for GSoC'19:
I will describe my journey from detail i.e from the 1st year of the college. I joined my college back in 2017 (July), I was not even aware of Computer Science. What are the different languages of CS, but I had a strong intuition of doing BTech from CSE only?
So yeah I was totally unaware of the computer science stuff, but I had a strong desire to learn it and I literally don’t know why I had this desire. After getting into college, I was learning HTML, Python, and C, also I am really thankful to my friends who really helped me to learn, building logic and making stuff out of it. During the 1st month of joining the college, I got to know what is Open Source, GSoC, Github due to my helpful seniors. But I was not into Open Source during my 1st year of college as I thought it is very difficult to start. In my 1st year, I used to do competitive programming and writing scripts in Python to automate various stuff. I never thought that I would even start doing Open Source development, also in the summer vacations after the 1st year I used to practice programming on HackerRank and learnt an awesome course called Automate the Boring Stuff with Python(which I think is one of the most popular courses for Python) which really helped me to build by Python skills.
Now the 2nd year came, I was totally confused between doing Open Source development or continue with my Competitive programming. But I wanted to know about Open Source development, so I thought to start now will be a good idea. I started attending meetups of OSDC(Open Source Developers Club) which is a hub of my college, which really helped me to know more about Open Source development from my seniors. I started looking for beginner friendly projects in Python on the website Up For Grabs, it’s really helpful for the beginners. So I contributed in a few of them, and in starting it was really tough for me but yeah I continued, which really helped me to at least dive into Open Source. Now I thought to start contributing in any bigger project, which has millions of lines of code which will be really interesting. So I started looking for the project, as I was into web development those days so I thought to find a project which matches my domain. So yeah I finally landed on Oppia:
Oppia
I started contributing into Oppia in November, so yeah in starting it was really difficult for me to solve any issue (as I wasn’t aware of the codebase which was really big), but yeah mentors at Oppia are really helpful, they guided me which really helped me to start my journey with Oppia. By starting of January I was able to resolve around 3–4 issues, which helped me to become the collaborator at Oppia, afterward I really liked contributing to it and I was able to resolve around 9–10 issues by the end of February, which landed me to become a Team Member at Oppia which was really a confidence boost and indication for me that I am in the right direction.
Also in February, the GSoC organizations list was out, and yeah Oppia was also participating in it. The project ideas of Oppia were really interesting, I became even confused to pick anyone because there were 4–5 ideas which seemed interesting to me. After 1–2 days of thought process I decided to go for one of them, i.e “Asking students why they picked a particular answer”, a full stack project.
I started making proposals on it, from the first week of March. I used to get my proposal reviewed frequently from the mentors, which really helped me to build a good and strong proposal.
I must say a well-defined proposal is the most important key for getting selected in GSoC, also you must have done some contributions to the organization earlier which I think really maximize your chances of selection in GSoC.
So after my proposal was made, I submitted it on the GSoC website.
Result Day:
It was the result day, by the way, I had the confidence of being selected, but yeah I was a little bit nervous. All my friends were asking when is your result coming, I told them it will come at 12.30AM (IST). Finally, the time came when I refreshed the GSoC website, Voila the results were out. I opened the Oppia organization page, and yeah my name was there. That was the day I was really happy and satisfied, I was thinking like I have achieved something in my life. It was a moment of pleasure for me, I called my parents and told them my result, they were really happy for me.
I say cracking GSoC is worth it, the preparation you do, the contributions you do, the making of the proposal is really worth.
I got so many messages from my juniors, friends, and seniors, they congratulated me. After that when I uploaded my result of Facebook and LinkedIn, there were tons of comments and likes on the post. So yeah that’s my journey.
By the way, I am writing this post after really late, sorry for it. I must have done it earlier, but due to milestone 1 of GSoC, I was busy.3 -
It is the time for the proper long personal rant.
Im a fresh student, i started few months ago and the life is going as predicted: badly or even worse...
Before the university i had similar problems but i had them under control (i was able to cope with them and with some dose of "luck" i graduated from high school and managed to get into uni). I thought by leaving the town and starting over i would change myself and give myself a boost to keep going. But things turned out as expected. Currently i waste time everyday playing pc games or if im too stressed to play, i watch yt videos. Few years ago i thought i was addicted, im not. It might be a effect of something greater. I have plans, for countess inventions, projects, personal, for university and others and ALL of them are frozen, stopped, non existant. No motivation. I had few moments when i was motivated but it was short, hours or only minutes. Long term goals dont give me any motivation. They give as much short lived joy, happines as goals in games and other things... (no substance abuse problems, dont worry). I just dont see point of my projects anymore. Im sure that my projects are the only thing that will give me experience and teach me something but... i passed the magic barrier of univercity, all my projects are becoming less and less impressive... TV and other sources show people, briliant people, students, even children that were more succesful than me
if they are better than me why do i even bother? companies care more for them, especialy the prestigious ones, they have all the fame, money, funding, help, gear without question!
of course they hardworked for ther positions, they could had better beggining or worse but only hard work matters right?
As i said. None of my work matters, i worked hard for my whole life, studing, crafting, understanding: programming, multiple launguages, enviorements, proper and most effcient algorithms, electronic circuits, mechanical contraptions. I have knowlege about nearly every machine and i would be able to create nearly everything with just access to those tools and few days worth of practice. (im sort of omnibus, know everything) But because had lived in a small town i didnt have any chances of getting the right equpment. All of my electronical projects are crap. Mechanical projects are made out of scrap. Even when i was in high school, nobody was impressed or if they were they couldnt help me.
Now im at university. My projects are stagnant, mostly because of my mental problems. Even my lifestyle took a big hit. I neglect a lot of things i shouldnt. Of course greg, you should go out with friends! You cant dedicate 100% of your life to science!
I fucking tried. All of them are busy or there are other things that prevent that... So no friends for me. I even tried doing something togheter! Nope, same reasons or in most cases they dont even do anything...
Science clubs? Mostly formal, nobody has time, tools are limited unless you designed you thing before... (i want to learn!, i dont have time to design!), and in addition to that i have to make a recrutment project... => lack of motivation to do shit.
The biggest obstacle is money. Parts require money, you can make your parts but tools are money too. I have enough to live in decent apartment and cook decently as well but not enough to buy shit for projects. (some of them require a lot or knowlege... and nobody is willing to give me the second thing). Ok i found a decent job oppurtunity. C# corporation, very nice location, perfect for me because i have a lot of time, not only i can practice but i can earn for stuff. I have a CV or resume just waiting for my friend to give me the email (long story, we have been to that corp because they had open days and only he has the email to the guy, just a easier way)
But there are issiues with it as well so it is not that easy.
If nobody have noticed im dedicated to the science. Basicly 100% scientist that want to make a world a better place.
I messaged a uni specialist so i hope he will be able to help me.
For long time i have thought that i was normal, parent were neglecting my mental health and i had some situations that didnt have good infuence on me as well. I might have some issiues with my brain as well, 96% of aspargers symptoms match, with other links included. I dont want to say i have it but it is a exciuse for a test. In addition to that i cant CANT stop thinking, i even tried not thinking for few minutes, nope i had to think about something everytime. On top of that my biological timer is flipped. I go to sleep at 5 am and wake up at 5pm (when i dont have lectures).
I prefer working at night, at that time my brain at least works normaly but i dont want to disrupt roommates...
And at the day my brain starts the usual, depression, lack of motivation, other bullshit thing.
I might add something later, that is all for now. -
JSON de/serializer for C++, recommendations?
I used boost serialization until now, and it's fine.
But I will need to send some stuff over REST protocol to my future-web-GUI.
I would like something that is easy to build, not bloated, and could handle class serialization.
Shoot!18 -
I get this compliment when I just started to learn C# and wrote a class to convert DB time zone on azure windows and Linux app services.
“Wow, didn’t know you can convert nullable datetimeoffset this way, I’m going to use this class in rest of our Projects. “
It really boost my mood for weeks.1 -
Roses are red
Boost I need you
You do so much I cannot breath
You fucking need to be hacked around every time I have to compile you for a different compiler or VS version getyourshittogheter fucking hell it makes me hate you -
Ok so one of the advantages of Java is that it has a huge ecosystem of libraries.
Then why is there no fucking decent graph library?! I just need to display this planar graph. I'm so fucking close to learning c++ and using boost to layout the graph.
I'm seriously stuck with this since like a week.
FUUUUUCK10 -
std::chrono is::a::fucking::pile::of::dog::shit. What a fucking disgrace. Hated it in boost, now this shit is in std. Each time I use it, I have to use google. Google should become part of std chrono in c++, without it you cannot write chrono code.
To make time_point member in your own class you have to do this: std::chrono::high_resolution_clock::time_point t; ... WTF7 -
I honestly have come a long way. But I still have these moments when I just lose confidence In myself, and while grieving it can be worse/more frequent.
I’m being taught some networking programming from this person I befriended and it’s going wonderfully! But I don’t know how much I’m taking in. I don’t know if I’ll be able to completely understand while I’m using what I’m learning, but I guess part of the learning is by using and doing. But what if I need to change it up for a different purpose but I don’t know how?
What if I’m not programming enough? When working on this project/learning the stuff from my new teacher friend to actually make some of the stuff I usually work on that for 30 mins to an hour and a half maybe even 2. Relax, do some college, play games, then later I’ll try to work through a few exercises of my C# WinForms book.
And before you say it I’m not balancing too much on my head. I’ve learned GUI’s before with Python I’m just reflecting that to C# and it’s easy and I’m always in a separate headspace for networking. But it all just doesn’t feel like enough?
It also doesn’t help that i don’t feel like I’m doing anything special that I can boost my confidence with. Usually in a project I won’t feel like I’m doing anything until a cool or special feature is made and I know that’s bad I hate it but I can’t avoid it and I want to feel good even when nothing completely out of this world is made that day.
And I’ve definitely come a long way I’m proud of myself but I just hate getting these feels. And It happens a bit when I’m learning because I’m afraid I’m not learning and I’m gonna keep copy pasting the same code snippets for different projects and I don’t want that I want to be able to fucking edit and change it or make a completely new one of whatever it is but my design but I guess that takes experience with it first.
Thanks for coming to my TED talk -
Ok, I'm starting with C++, I want to do a couple of things without reinventing the wheel
I want to parse flags passed to my soft… — Use Boost
Ok, now I want to do some checks about filepa… — Use Boost
What about getting a file size without having to pull my hair out ? BOOST
Alright, Boost is actually the jQuery of C++, right ?8 -
It's weird no one seems to be mentioning a major problem with mordern Intel CPUs: Turbo boost. On newer laptops I always turn gimmick off now. Half the time the safeties don't kick in and you end up with 100+ degree C on your CPU for sustained amount of time (especially compiling!). Keep that happening over a couple of years I would not be surprised if that contributed heavily on battery stress and the shortening of the product... *cough* Apple "80°C+ idling is totally normal" *cough* (Actual reply from Apple when I queries about my McToasty 2015!)
Anyone else noticed this issue?2 -
first contact was with games. There are actually 2 events I connect with that, but I cant remember which one was first - so here you have both:
Both happened on the Computer from my dad - Windows 95 with Boost button - which of course was always active to make everything super fast :D (yeees, now I now that it actually made it 'slower')
1) Playing Lemmings from 2 Floppy’s (3.5inch 1.44bm)
Until my dad kept Disc 1 in his Jacket for whatever reason I cant remember (maybe because I played to much) and my mother had the great Idea of washing the jacket... bye bye lemmings :( never played it again since then, but still remember the music and soundefects. still love them :)
2) Trying to install AoE on the PC. But since HDDs where cheap (not) and had a ridiculously amount of space (not) (sth. ~250MB) and AoE needed ~150MB, my young and smart me came up with the amazing solution to delete the largest folder on disk, which was C:/WINDOWS. I do not have to mention that my dad was not amused ^^ -
Already starting to regret trying to learn c++ AND test driven development at the same time. Do you think i can even get the boost-test headers located anywhere from a binary package installation.
3 days on no learning code cause i cant even get the testing suite up and verified.1 -
String char replacement in C++ (according to SO):
Boost - replace_all(str1, str2);
C++ STL - 12 lines of code to iterate over the length of the string and store the result in a <char> vector.
Noooooooope. Thank God for Boost.1 -
In Python my favs are lxml and sqlalchemy. Very simple to use and solve the problem of xml and database very easily.
In C++ my fav is the Qt system of libraries. Very nice solutions for structuring an application, cross platform, good memory management, COW if you want it, etc. Every release gets better and better. Oh and boost should get an honorable mention. I really like the ranges library and some of the more esoteric libs it provides.2 -
With C++11, fell in love with std::enable_if and others in type_traits.
Lets you take generic programming to a whole new level. I never used it when this was part of boost thinking it didn't make as much sense. Now, I like to qualify my template definitions to be as restrictive as possible based on the expected usage. -
Trying to run the examples of Boost networking in two programs with QtCreator. Same Qmake file, one program compile, the other has a linker error. Why?????2

Hey fellow c++ devs, i have a question. I am currently working for a company that has a system with more than 300 000 thousand lines of maintained code and it is written in C++03. A lot of it utilises boost and custom performance work arounds and migration is currently out of the question, but I would really love to see some Cpp11 sugar in the code-base. I know there might not be too much business value to this potential endevour, but what do you think?1
