Just taking the temperature - how many people would be interested in a devRant podcast? We'd probably start with it being every other week.
It would feature things like inside devRant updates, guest interviews, rant readings, and anything else fun we could think of.
Hi there fellas,
I'm new to devrant and I'll like to share with you my first story.
It was my first payed job. A good friend of mine (media designer in print) called me "My customer needs a website, do you think you can do that?"
At this time I've never build a single page, so my answer was "Of course, easy-peasy".
She told me it was a family business and a nationwide player in finance sector.
I met the CEO, did my research and build a prototype. Well, the CEO and his staff liked it so I finished the website and prepared for the first review.
I booted the laptop and tried to connect to their network. There was none. They just never had a wireless connection not a single cable in the entire office. That was the time I realized that I work for a family business.
The CEO was an ancient guy who probably saw Jesus Christ hanging on the cross in personal and internet is weird thing controlled by the devil himself.
I took the laptop and went over to the CEOs personal office, plugged the network cable out of his Computer and into the laptop. Finally I could show them what I've done.
He took a look at it and called for his assistant. "Might you print that website for us?" That was my second wtf moment.
The assistant returned with a half chopped down and bleached rainforest that contained an image of their new website.
I tried to tell him that a website on paper can't show him the functions n shit, but he looked at me like I was talking two foreign languages at once.
So we reviewed the website on paper and his one and only problem was the size of the letters. "I can't read it well, please make the text bigger" At this moment I wanted to hit my forehead on the table and tell him that it is normal to have readings difficulties when you are walking the shores of Styx.
At the end everything went well, but I realized that dealing with customers is a lot more difficult than developing something for them. The future should prove me right.
My first story about my first job.
Thank you for reading 😊12
Development plus laboratories is kind of my expertise, so I ended up in a little grimey HR office looking out over the factory floor of a cocoa processing facility. I was applying for an automation job, a temp thing for three weeks, updating some ugly scripts which took readings from machines and threw them into excel sheets.
"We don't think a developer like you has enough experience working in an environment like this. Safety and working in sterile conditions is very important to us"
I had sent them my certifications in advance, plus references to the work I did in a biosafety level 3 lab for JnJ and cleanroom work at an aerospace company.
There were fat sweaty guys on sneakers, taking cocoa paste samples right next to the window.
They ended up hiring a friend of mine with zero experience, for minimum wage.
Just be fucking honest, don't waste my time with courtesies and lies. If they had just told me about the low salary indication, I would still have done the work. I was in between jobs anyway, bored, trying to fill up some spare time.4
I propose a list of interesting readings. Not limited to developing.
Yes, I'm in need of something new to read...
I'll start in the comments, feel free to comment new readings or critique the ones proposed.29
So I'm using a temperature sensor to detect the air temperature in a box. I'm getting readings of about 225°C. Thinking that's weird I check the algorithm converting the input to celceius. Seems legit. Okay must be hardware, let's try resetting the sensor into the board. Turns out the readings weren't lying... Long story short, if you reverse the polarity of a temperature sensor you get a very powerful heater...5
Can someone recommend me some good js readings ( algorithms / pure js / no framework related ) ? I just discovered this website: http://www.thatjsdude.com/ and I want more ...4
In a real-time multiplayer competitive game where you control a vehicle, is it feasible to simulate the whole thing on server side, such that the client only sends controls and receives sensor results? I mean like the client doesn't even know its own precise rotation, just the readings of a gyroscope and an accelerometer which are both susceptible to errors, and deduces the "down" direction from those two and approximate control forces. This would both solve hacking (writing a good robot is just as challenging) and lead to fun results like an attitude indicator going crazy from a gust of wind.18
Compass readings on Android phone might get messed up when iPhone gets close to it.
I have azimuth showing in my app, we wanted to check if it's working and we put an Android phone on the table and iPhone with compass app running. Android showed 20 degrees less. Colleague picked up iPhone and azimuth on Android changed by 20 degrees :D2
I think another intriguing job asides programming is engineering (*for some*). A week has past and I've been on the hike assisting my beloved brother on his contracted engineering job while I am less occupied. The job is based on 🗼Tower analysis and It's quite risky as you'd have to climb up to 56 meters high just to take readings of antennas, and fix some other stuffs. The only thing I find intriguing about this job is his love for it, funny enough he also thinks I love the job too and I guess I'm guilty for his thoughts (*Sorry bro, I love the job for you not me*).
With my little experience so far on my *new brotherly job* I noticed the most hectic task isn't going up and down the tower taking readings but at the end of all operations, he'll have to gather the values and snapshots he took while on the tower to prepare reports on msword & excel for the other buttwags at the office (or home I guess)
then archive and sends via mail. Seeing this lengthy process I was forced to ask why he wasn't using any reporting tool like Jotforms or any other equivalent and I was willing to look up some recommendations for him, his reply was: "I'm already used to this form of reporting, its what I was trained with and what the company provided, nevertheless a friend of mine suggested something of such weeks back but I would have to pay monthly fee for its usage which is quite on the high side and I don't think I'd prefer that."
Sounds convincing but not enough, okay here is another deal: You use an android phone right? and at my office we work on system automation (*basically does not know what I do for a living probably thinks I'm a hacker the illegal one*), how about i design you an android app for you to capture the tower data and a PC software for you to auto generate the msword & excel reports, I can get this ready for you in less than 5 nights (*I've got less task on my desk, and was willing to take the timeout to prepare the solution that he needed, all I needed to hear for a kick start was an "Okay" just to be sure he wants it*) I suggested and re-assured but up to this point he still declined my offer and is willing to stick with his current reporting pattern (*Me died*).1
Helped a friend code an Android weather app that got readings from 4 different sites and could rate their accuracy based on one trusted site.
Didn't think I had material for a rant but... Oh boy (at least at the level I'm at, I'm sure worse is to come)
I'm a Java programmer, lets get that out of the way. I like Java, it feels warm and fuzzy, and I'm still a n00b so I'm allowed to not code everything in assembly or whatever.
So I saw this video about compilers and how they optimize and move and do stuff with the machine code while generating the executable files. And the guy was using this cool terminal that had color, autocomplete past commands and just looked cool. So I was like "I'll make that for my next project!"
So I Google around and find a code snipped that gives me "raw" input (vs "cooked" input) and returns codes and I'm like 😎. Pressing "a" returns 97 (I think that's the ASCII value) and I think this is all golden now.
No point in ranting if everything goes as planned so here is the *but*
Tabs, backspaces and other codes like that returned appropriate ASCII codes in Unix. But in windows, no such thing. And since I though I'd go multiplatform (WORA amarite) now I had to do extra work so that it worked cross platform.
Then I saw arrow keys have no ASCII codes... So I pressed a arrow key and THREE SEPARATE VALUES WERE REGISTERED. Let me reiterate. Unix was pretending I had pressed three keys instead of one, for arrow keys. So on Unix, I had to work some magic to get accurate readings on what the user was actually doing (not too bad but still...). Windows actually behaved better, just spit out some high values and all was good. So two more systems I had to set up for dealing with arrow keys.
Now I got to ANSI codes (to display color, move around the terminal window and do other stuff). Unix supports them and Windows did but doesn't but does with some Win 10 patch...? But when tested it doesn't (at least from what I've seen). So now, all that work I put into making one Unix key and arrow key reader, and same for Windows, flies out the window. Windows needs a UI (I will force Win users, screw compatibility).
So after all the fiddling and messing, trying to make the bloody thing work on all systems, I now have to toss half the input system and rework it to support UI. And make a UI, which I absolutely despise (why I want to do back end work and thought this would be good, since terminal is not too front end).2
Been working on trying to get JMdict (relatively comprehensive Japanese dictionary file) into a database so I can do some analysis on the data therein, and it's been a bit of a pain. The KANJIDIC XML file had me thinking it'd be fairly straightforward, but this thing uses just about every trick possible to complicate what one would think would be a straightforward dictionary file:
* Readings and Spellings/Kanji usage are done in a many-to-many manner, with the only thing tying them together being an arbitrary ID. Not everything is related, however, as there can be certain readings that only apply to specific spellings within the group and vice versa. In short, there's no way to really meaningfully establish a headword fora given entry.
* Definitions are buried within broader Sense groups, which clumsily attach metadata and have the same many-to-many (except when not) structure as the readings/spellings.
Suffice to say, this has made coming up with a logical database schema for it a bit more interesting than usual.
It's at least an improvement over the original format, however, which had a couple different ways of setting up the headword section and could splatter tagging information across any part of a given entry. Fine if you're going to grep the flat file, but annoying if you're looking for something more nuanced.
Was looking online last night to see if anyone had a PHP class written to handle entries and didn't turn anything up, but *did* find this amusing exchange from a while back where the creator basically said, "I like my idiosyncratic format and it works for me. Deal with it!": https://sci.lang.japan.narkive.com/...
Grateful to the creator for producing the dictionary I've used most in my studies over the years, but still...3
I'll move in with my girlfriend in August. So it's time to get a cleaning robot!
To either iRobot Roomba or Neato Botvac.
Which would you suggest and why? From the readings I've done so far, when it's about performance it's Roomba 980 >= Botvac Connected > Roomba 880, but then again the Roomba 980 is a lot more expensive.
Is there a dev, as lazy as I am with hands on expirience?
Note: there will be only a small carpet below the table in the living room and the appartment will have 4 rooms: living, sleeping, kitchen and bath. As the house is a little older, there's a "obstacle" the doors between the rooms to climb of about 1cm.
Thanks for suggestions in advance. On another note: I'm planing to get connected lightbulps and speakers, so we'll be able to control most of the stuf from our smartphones. So far I don't see any advantages, incorporating a vacuum bot in there, as long as you can set a scedule, any thoughts on that?5
TL;DR: Can anyone recommend or point at any resources which deal with best practices and software design for non-beginners?
I started out as a self-taught programmer 7 years ago when I was 15, now I'm computer science student at a university.
I'd consider myself pretty experienced when it comes to designing software as I already made lots of projects, from small things which can be done in a week, to a project which i worked on for more than a year. I don't have any problems with coming up with concepts for complex things. To give you an example I recently wrote a cache system for an android app I'm working on in my free time which can cache everything from REST responses to images on persistent storage combined with a memcache for even faster access to often accessed stuff all in a heavily multithreaded environment. I'd consider the system as solid. It uses a request pattern where everthing which needs to be done is represented by a CacheTask object which can be commited and all responses are packed into CacheResponse objects.
Now that you know what i mean by "non-beginner" lets get on to the problem:
In the last weeks I developed the feeling that I need to learn more. I need to learn more about designing and creating solid systems. The design phase is the most important part during development and I want to get it right for a lot bigger systems.
I already read a lot how other big systems are designed (android activity system and other things with the same scope) but I feel like I need to read something which deals with these things in a more general way.
Do you guys have any recommended readings on software design and best practices?3
During my readings of Nim I found a technique known as stropping.
This gives devs the ability to use keywords as identifiers.
var `var` = "fucking why?"
Can anyone tell me WHY would someone subject themselves to such confusion notion? Mind you Nim has large features for macro programming and the creation of dsls, i have not gotten far enough to assess this, but what other use could you highly knowledgeable lads and lasses think of?22
Not being able to lol at "Monad is a monoid in the category of endofunctors." joke even after several readings of articles/guides online.
Anyone worked with the Nordic API before? Trying to get two small VL53L0X sensors to work, but only managing one. I'm setting ethe address to two different ones when I need the readings, but it still isn't giving any sadly. Any suggestions?
Anyone else get told their rates are too high (by potential clients)? Too low (by fellow freelancers)? How does one put a value to their time and still stay market competitive?
Details: USA only. Not on any platforms such as freelancer, upwork, or fiver. Cost of living is Portland Oregon standards. Ask for any other details.
Looking for thoughts, recommended readings, any helpful input would be awesome.2
DevOps With Ruby and Chef on FreeBSD (and Linux)
I am Ops and Dev by heart. I have always automated *nix systems long before any automation framework was invented because I am pretty lazy. Doing stuff more than once manually is just one time too often for me. Imho Ruby is a really elegant language. The same applies for the tools that are built around it. The Chef ecosystem fits into this with its own elegance and stability perfectly because the server is Erlang driven and the rest is Ruby.
Being a Linux and BSD user since the early 90s I have always loved a *nix system for it's concepts and simplicity. One command for exactly one purpose and everything is combineable like letters are combinable to words in my mother language. I have always loved FreeBSD more though. Imho it is even more focused on simplicity. Because it is a really clean approach of system design that envies a base system and keeps 3rd party separated in a clean way for example. It also values classic UNIX philosophies that most Linux distros these days abandon but which saved my life multiple times through better design and execution that also focuses alot more on stability, fault tolerance and ease of use than any Linux I have come across. The hardcore guys should read "Design and Implementation of the FreeBSD Operating System", compare the readings to the Linux way of things and see for themselves.*
