I just can't understand what will lead an so called Software Company, that provides for my local government by the way, to use an cloud sever (AWS ec2 instance) like it were an bare metal machine.
They have it working, non-stop, for over 4 years or so. Just one instance. Running MySQL, PostgreSQL, Apache, PHP and an f* Tomcat server with no less than 10 HUGE apps deployed. I just can't believe this instance is still up.
By the way, they don't do backups, most of the data is on the ephemeral storage, they use just one private key for every dev, no CI, no testing. Deployment are nightmares using scp to upload the .war...
But still, they are running several several apps for things like registering citizen complaints that comes in by hot lines. The system is incredibly slow as they use just hibernate without query optimizations to lookup and search things (n+1 query problems).
They didn't even bother to get a proper domain. They use an IP address and expose the port for tomcat directly. No reverse proxy here! (No ssl too)
I've been out of this company for two years now, it was my first work as a developer, but they needed help for an app that I worked on during my time there. I was really surprised to see that everything still the same. Even the old private key that they emailed me (?!?!?!?!) back then still worked. All the passwords still the same too.
I have some good rants from the time I was there, and about the general level of the developers in my region. But I'll leave them for later!
Is it just me or this whole shit is crazy af?3 -
For my final project as a first year computer engineer, I have to implement a FAT32 file system using a bare metal c++ compiler that will need to work on arduino uno/due....
I've only been in the computer engineering space for 2 months.
Not sure I can do it, but I'm going to try my best!
Wish me luck10 -
Help.
I'm a hardware guy. If I do software, it's bare-metal (almost always). I need to fully understand my build system and tweak it exactly to my needs. I'm the sorta guy that needs memory alignment and bitwise operations on a daily basis. I'm always cautious about processor cycles, memory allocation, and power consumption. I think twice if I really need to use a float there and I consider exactly what cost the abstraction layers I build come at.
I had done some web design and development, but that was back in the day when you knew all the workarounds for IE 5-7 by heart and when people were disappointed there wasn't going to be a XHTML 2.0. I didn't build anything large until recently.
Since that time, a lot has happened. Web development has evolved in a way I didn't really fancy, to say the least. Client-side rendering for everything the server could easily do? Of course. Wasting precious energy on mobile devices because it works well enough? Naturally. Solving the simplest problems with a gigantic mess of dependencies you don't even bother to inspect? Well, how else are you going to handle all your sensitive data?
I was going to compare this to the Arduino culture of using modules you don't understand in code you don't understand. But then again, you don't see consumer products or customer-specific electronics powered by an Arduino (at least not that I'm aware of).
I'm just not fit for that shooting-drills-at-walls methodology for getting holes. I'm not against neither easy nor pretty-to-look-at solutions, but it just comes across as wasteful for me nowadays.
So, after my hiatus from web development, I've now been in a sort of internet platform project for a few months. I'm now directly confronted with all that you guys love and hate, frontend frameworks and Node for the backend and whatever. I deliberately didn't voice my opinion when the stack was chosen, because I didn't want to interfere with the modern ways and instead get some experience out of it (and I am).
And now, I'm slowly starting to feel like it was OKAY to work like this.10 -
Soooo I think I have finally come to the point that I may have to create a YouTube channel, to teach software engineering from the ground up... and teach it the way the universities and everyone else should be teaching it, so that they have a solid foundation.... throwing hello world, and loops and variables at folks out of the box without any of the environment context or low level embedded register, even logic gate understanding
That lack of understanding is why, soooo many college students and younger folks, are actually pretty shitty engineers. Everything is high level languages and theoretical concepts to them. Nothing practical, that’s why there’s sooo many python and java developers that can’t for the life of them understand memory management, low level hardware interfacing etc, because the colleges don’t teach it the way it use to be taught.
I seriously fear 30 years from now or sooner when there are few embedded engineers only left till retirement, as without those folks the whole pyramid of electronics falls to pieces.
Java, C#, python, all that shit don’t run on the bare metal... there’s this magical layer of C, and assembler that does all the work just so folks can abstract their thoughts.
Either 1 of two situations will happen.. price of electronics will rise because the embedded guys are few and far between therefore salaries skyrocket... OR everything starts running shit like java on the metal, where there are a over abundance of developers, their salaries will be low because there are soo many but the processing power, space, and energy needed to run java natively causes electronics cost to increase
but regardless 30 years from now if those script kiddies are building everything I fear it cuz there’s gonna be memory leaks, and overflow issues everywhere.. shit be blowing up more than 4th of July.. lol
Soooo in effort to prevent that and keep the embedded engineers up, or atleast properly educate the script kiddies, I’m gonna make that YouTube channel.. 1 maybe 2 videos a week, 1-2 hours sessions each.. starting at the fucken ground and building up.39 -
Since fucking when did "bare metal" mean just running on an OS?? At a conference and literally everyone is like "we got kubernetes running on bare metal", got super excited for a bit because just the idea of that sounds amazing but they're using it as slang for "basically not in a container or vm."
Nothing exciting at all. Now we're patting ourselves on the back for getting software working without it being preconfigured as a container or a VM image. No one knows how to do anything any more. MUCH too much abstraction going on.
I guess it keeps me more employable, but the state of the world from a developer standpoint is just sad.
(For reference, this is what the first sentence of "Bare Metal" looks like on wikipedia "In computer science, bare machine (or bare metal) refers to a computer executing instructions directly on logic hardware without an intervening operating system.")4 -
I wanna meet the dumbass that decided it was a good idea to teach scratch, basic, java, or even python as a first programming language course in college.
I’m so sick of seeing developers out of with shitty code structure and practices, and absolutely no understanding of what is going on behind the scenes of the IDE when you push run.
In order to be a good engineer you MUST know the basics, the root level, bare bones, bare metal shit.
I fear the future, less and less software engineers are comming out of colleges, the majority today is script kiddies, and folks with some basic java experience.
Who the hell is going to be writing firmware in the future then?
It’s insane the lack of foundational skills these students get in college. If they would get a strong foundation in C, and C++ they can easily attack at problem in any language, but missing the foundation, and relying on IDEs.. you will never be-able to go from a knowing only a high level languages and scripts to Lower level problems.
RIP the future of Software Engineering
Welcome to the hell full of script kiddies27 -
Personal project: I design and build single-board computers with old processors like Z80, 6502 etc when I'm not being too lazy. A few run CP/M. One that's been more interesting in terms of digging deeper has been an 80C188, for which I've written a BIOS (despite the chip's built-in peripherals and interrupts being at non-standard addresses) mostly in C, which it can use to boot DOS from an image file on an SD card (bit-banged off the UART chip with FatFs). (Yes it's slow, but so is a 5.25" floppy.)
Work: My first project at my current job. Not particularly exciting compared to some stuff on here, but it got me into making useful contributions to the open-source CRM we used at the time. Was building a basic extension to deal with duplicated organisation names. So learned CiviCRM fairly deeply, a bit of Drupal, a bit of PHP. It's a shame we don't use that system any more, the community was cool.7 -
This will definitely trigger many but the truth regardless of how you feel is the greatest programmers are those who understand both the hardware level and software .. only then are you more than a dev or programmer.. you are an engineer...
I challenge the devs who dis believe to go out and learn to build circuits, write optimized, efficient bare metal code.: no sdk.. no api... no drivers ..remove the unneeded abstraction layers that have blinded you...build it yourself, expand your potential and understanding..
Not only will you become more valuable overall, but you will write better code as you are more conscious of performance and space and physics of the physical layer.
I’m not talking about Arduino or raspie
Those who stand strong that high level abstraction languages and use of third party apis is a sufficient sustainable platform of development are blind to reality.. the more people who only know those levels, the less people pushing the industry of the low level.., which is the foundation of everything in the industry.. without that low level software the high level abstractions and systems cannot run
Why did we have huge technology advancements from 70s to early 2000s.... because more people in our industry understood the hardware layer..: wrote the software at the less abstracted layers..
Yeah it takes longer todo things at that low level abstraction.. but good robust products that change the world and industry don’t take a few week or months to build.....
Take this with what you will... I’m just trying to open the eyes of the blind developers to the true nature and reality of our industry23 -
Going out on a limb here... have any of you done any bare-metal phone programming (not counting compiling like AOSP and such, like totally arbitrary code at boot-time, or bootloader coding, ideally) or know someone that has? A friend got bit by a bad iOS app on a jailbroken iPhone 8 (checkra1n, so no unsigned firms or anything) that has installed a bad iCloud lock on the device, and I need checkm8 shellcode to zero most of if not all of the NAND to get rid of it (since an iTunes restore preserves that data) and I can't figure out jack shit about how any of this works, since ARM isn't strict on what goes where in the address space or how to access hardware.11

About slightly more than a year ago I started volunteering at the local general students committee. They desperately searched for someone playing the role of both political head of division as well as the system administrator, for around half a year before I took the job.
When I started the data center was mostly abandoned with most of the computational power and resources just laying around unused. They already ran some kvm-hosts with around 6 virtual machines, including a cloud service, internally used shared storage, a user directory and also 10 workstations and a WiFi-Network. Everything except one virtual machine ran on GNU/Linux-systems and was built on open source technology. The administration was done through shared passwords, bash-scripts and instructions in an extensive MediaWiki instance.
My introduction into this whole eco-system was basically this:
"Ever did something with linux before? Here you have the logins - have fun. Oh, and please don't break stuff. Thank you!"
Since I had only managed a small personal server before and learned stuff about networking, it-sec and administration only from courses in university I quickly shaped a small team eager to build great things which would bring in the knowledge necessary to create something awesome. We had a lot of fun diving into modern technologies, discussing the future of this infrastructure and simply try out and fail hard while implementing those ideas.
Today, a year and a half later, we look at around 40 virtual machines spiced with a lot of magic. We host several internal and external services like cloud, chat, ticket-system, websites, blog, notepad, DNS, DHCP, VPN, firewall, confluence, freifunk (free network mesh), ubuntu mirror etc. Everything is managed through a central puppet-configuration infrastructure. Changes in configuration are deployed in minutes across all servers. We utilize docker for application deployment and gitlab for code management. We provide incremental, distributed backups, a central database and a distributed network across the campus. We created a desktop workstation environment based on Ubuntu Server for deployment on bare-metal machines through the foreman project. Almost everything free and open source.
The whole system now is easily configurable, allows updating, maintenance and deployment of old and new services. We reached our main goal for this year which was the creation of a documented environment which is maintainable by one administrator.
Although we did this in our free-time without any payment it was a great year with a lot of experience which pays off now. -
PouchDB.
It promised full-blown CRDT functionality. So I decided to adopt it.
Disappointment number one: you have to use CouchDB, so your data model is under strict regulations now. Okay.
Disappointment number two: absolutely messed up hack required to restrict users from accessing other users’ data, otherwise you have to store all the user data in single collection. Not the most performant solution.
Disappointment number three: pagination is utter mess. Server-side timestamps are utter mess. ANY server-side logic is utter mess.
Just to set it to work, you need PouchDB itself, websocket adapter (otherwise only three simultaneous syncs), auth adapter (doesn’t work via sockets), which came out fucking large pile of bullshit at the frontend.
Disappointment number four, the final one: auth somehow works but it doesn’t set cookie. I don’t know how to get access.
GitHub user named Wohali, number one CouchDB specialist over there, doesn’t know that either.
It also doesn’t work at Incognito mode, doesn’t work at Firefox at all.
So, if you want to use PouchDB, bear that in mind:
1. CouchDB only
2. No server-side logic
3. Authorization is a mess
4. Error logs are mess too: “ERROR 83929629 broken pipe” means “out of disk space” in Erlang, the CouchDB language.
5. No hosting solutions. No backup solutions, no infrastructure around that at all. You are tied to bare metal VPS and Ansible.
6. Huge pile of bullshit at frontend. Doesn’t work at Incognito mode, doesn’t work at Firefox.8 -
Hello devRant!
Man its been a while, i havent logged in here in like 4 years.
Recently ive been getting into home-labbing, and i thought to myself
"all of these people on youtube/reddit run Plex on pre-built NASs that have awful celerons and whatnot, we can do much better!"
And by "much better" i meant a bare metal k8s cluster.
My hybris knows no bounds apparently.
Turns out this shit is quite hard.
Really gives u an appreciation of just how much stuff cloud providers magically abstract away....
My final goal is to run stableDiffusion on this thing, even know i know full-well the moment i try Nvidia will fuck me raw with some hidden enterprise subscrition :) -
I have a rant. A genuine rant, not a funny story, etc.
I want a keyboard. I need one. It can cost €500, as long as it won't break in a year and fulfils all my needs. Make it a €1000, I don't care. What are my needs then? Well...
It has to be a split keyboard - two halves. But wireless in every aspect, ergonomic, with multimedia keys on its outer edges (preferably pointing outwards, not up) and a heavy metal trackball on the right outer edge (preferably upper right corner). That's a bare minimum.
On top of that it probably some magnetic scrolls for things like navigating pages, changing volume and fidgeting in general wouldn't hurt. Also I'd prefer it to snap back into a one-piece whenever I need it to lie on my knees, e.g. when I type while sitting on a coach (I have a coach PC setup, no desk, and there's a reason). Why do I need it to split then...?
I had an accident. Kind of broke my back when I was 11. It's mostly okay now after couple years of rehabilitation and many more years of careful living. Luckily the only two wheels I ride on are powered by a 105.97 hp @ 9,970 rpm engine. Still, I try to be careful so I tried tons of work hygiene techniques over the years and I found out anything over 2 hours is best done while lying flat.
Coding while lying flat has its challenges, mostly focused around screen and input. Ever since I got a VR headset half of them got solved but the other half - acquiring a suitable keyboard - it's very hard to satisfy. I tried that with a one-piece keyboard lying on my stomach. Turns out actively bending elbows quickly wears them out (hello tennis players). So a split keyboard it has to be. So far I tried 4 different ones and I had to modify the cable connecting both halves in each and every one of them so that it'd be long enough to go behind my back. The main cable itself I only had to modify once because usually there're extensions available.
Apart from cables, all of those keyboards had issues. Starting from some kind of de-syncing when keys from both halves would randomly register in a wrong order - I didn't know it's possible with a cable connected halves... I did try two generic WiFi keyboards (using one for each hand) and they unfortunately suffered from that very same issue but I was sure it wouldn't happen if the device was designed to be a one unit from the very beginning, right? And yet it in 2 of the tested devices.
Other than that, plugs disconnecting on their own forcing me to take off the headset and fiddle around, too high key travel that'd strain the wrists after a few hours, even the noise that would wake up my girlfriend sleeping in a separate room were all a common issue (I briefly had an almost completely silent WiFi mechanical keyboard from Logitech we both really liked, but it was a one-piece). Once I got a split keyboard that was "natively" WiFi but not only the two halves were still connected with a cable that turned out to be way too short for my needs, it also had a very noticeable lag despite the high price - a lag way higher than any of the cheap WiFi keyboards I owned in the past. So I sent it back. Now IDK what to do because AFAICT there are no more models available, at least where I live.
So yeah, I need a keyboard and I'll probably have to make one myself. Sorry, just had to vent.5 -
@BindView Thank you for introducing Scaleway to me (don't remember which rant you commented on).
Their rates for bare metal servers are really attractive!3 -
Kids these days and their ultrasonic scalpels. Back in _my_ day, we were doing sugreries with _real_ scalpels made of bare metal. Who cares that ultrasonic ones are way less invasive and it heals faster! If you’re using an ultrasonic scalpel, you’re not even a real surgeon. What’s next? Computer does a surgery for you while you wiggling around the controllers? WHAT DO YOU MEAN ITS ALREADY BEING DONE!? What happened to this country!4

I have never understood people ranting about how Linux is incompatible with their machines. Back in 2006 what ever machine I had tried Linux on was working better with it. More than that all the drivers were working out of the box and the only problem that could possibly happen was with graphics.
FF 10 years. I am using MacBook for some time now and I did no installation of Linux for couple of years now except on bare metal servers. And have just bought my sister a new hp envy. Nothing fucking works. Not even wifi. Installation is hanging and I do not fucking know why! Her previous computer had problems with wifi. If wifi is turned on you could not turn the fucking pc off. It would fucking freeze.
Well fuck my life :(9 -
Part 2 of my distro hunt
So Manjaro it is (99% sure about it). Now, I'm coming from Kubuntu, which has been pretty nice since pretty much all production environments I deal with run Ubuntu. Now, switching to Arch and also Pacman, that most likely means that I wont be able to run all development environments locally on "bare metal" like I'm used to. I guess I could run everything in Docker, but that seems like a bit of a hassle. What's your ideas/solution?15 -
I am currently running a heavily modded version of Ubuntu 18.04. I remove gnome applications, installed xfce with sddm for my login manager, plus removed a bunch of their pre-installed applications. I mostly use AppImages and snaps for installations with occasionally using apt for packages I am too lazy to build or are not in snap form.
I have been contemplating switching to Arch/Antegros/Manjaro. Mostly because I am crazy and heard that I could get a performance boost and I like being more in control of my own software.
My question is this, does it make sense for me to switch distros? Also, I'd like to have a close to the metal Arch install, but last time I did that I got annoyed with configuring too much from the bare bone, took me like close to an hour of setup, it was not hard, just really tedious.... Is Antegros/Manjaro have options to be really close to the bare-metal? Is there maybe a really good install script that I can just tweak some basic settings for?3 -
Itd be cool if we could get something like Schenzen.Io going, but you build the chips from the gates up
Maybe package them into modular units, and connect those at a higher level or abstraction, ad infinitum.
Then add access to virtual LCD output, and other peripherals, or even map output to real hardware, essentially letting you build near bare-metal virtual machines.
Dont know about that last part, but the closest I've seen to the rest is circuit simulator and again, schenzen.
On the machine learning front I figured out I need about ten times as many training samples as validation samples, or vice versa. I'll have to check my notes. Explains why I could get training loss below 2.11
Also, I'm looking at grouping digits, and trying different representations. I'm looking at the hidden variables for primorials to see what that reveals. And I realized because of the amount of configurations and training that I want to do, even a personally built cloud isnt going to be sufficient. I'm gonna have to rent someone else's hardware and run it "in duh cloud."
Any good providers that are ridiculously upfront for beginners to get started with? Namely something cheapish.3 -
Sometimes my hatred for code is so.. overwhelming that I think I need a sabbatical or should even stop altogether.
Let's face it. All code sucks. Just on different levels.
Want to go all bare metal? Love low level bit fiddling. Well, have fun searching for concurrency, memory corruption bugs. Still feel confident? Get ulcers from large C/C++ code base already in production, where something in the shared memory, function pointer magic is not totally right?
So you strive for more clean abstractions, fancy the high level stuff? Well, can you make sense of gcc's template error messages, are you ready for the monad, leaving behind the mundane everyday programmers, who still wonders about the scope of x and xs?
Wherever you go. Isn't it a stinking shit pile of entropy, arbitrary human made conventions? You're just getting more familiar with them, so you don't question them, they become your second skin, you become proficient - congrats you're a member of the 1337.7 -
Bought a new Bare-metal Server in India and SSH to it was visibly slow (even when it's a 1GBpS line)
Did a trace-route via my location in South East Asia
The pings went from SEA -> San Jose (im guessing US) -> … more US -> Chiba (Japan) -> … more Japan -> Singapore -> India.
So it crosses CONTINENTS and OCEANS even though both are in Asia, connected by land.
Also, there's direct submarine cable route to Singapore, so why go to US in the first plane :v
Idk whom to blame but have internet routes always been this unmanaged/inefficient? I was sure DCs go out of their way to ensure the shortest connection route is followed -.- but look at this ffs7 -
Just installed ubuntu-server bare metal.
Neither of the ethernet ports works.
Honestly, this is exactly the kind of shit that pushes people to Mac and Windows on the desktop.4 -
I spent the easter weekend migrating a bare metal Windows installation to a Proxmox VE server with a Windows VM (and set up an rdp client).2

Whenever I see the name @CoffeeBoy come up I think to myself:
-Umm hey I think we just ran out of coffee,
-Aw shit and we are working overtime till we finish.
-Are you thinking what I'm thinking ?
-Are you thinking about how good it would be to be a cat.
-Uuh no why do you want to be a cat ?
-Well duuh cat's sleep all day. It's great !
-They also live for only 15 years so I would think in total you will sleep more than cats do.
-You like to ruin things for me don't you.
-I call it productive refactoring. But getting back on topic. I hear we have a new intern ?
-Yeah, that's Jim over there.
-Well lets tell him to get us coffee.
-Oh yeah that's a good idea, because interns already have the bare minimum of expectations from their life anyways !
-Hey Jim, yeah you Jimmie buddy can you get us a few cups of coffee we really need those to stay functioning right now.
-Yeah sure, what do you need.
-George drinks cappuccino, you can get me whatever. Thanks man here is the money. Buy yourself a cup too it's on me.
-Oh thanks.
*Jim walks out of the room*
30 minutes has passed...
-Dude where is Jim at ? It shouldn't be that hard to get 3 cups of coffee from just a few blocks away.
-I hope he didn't get robbed or something he has MY money on him.
*22 minutes ago, jim walks out of the coffee shop carrying the 3 cups securely held under his arm *
-I thought he was just gonna use me as an errand boy or a coffee boy to be exact in this case. But it's nice of him to also pay for my cup. Maybe they are not such bad--
His sentence got cut off by the sudden impact with a metal surface at high velocity. He got hit by a car while he was crossing the street, too deep in thought to notice the speeding car in time.
After hitting Jim the car suddenly come to a halt with a screech noise from it's tires.
But it was too late the impact shattered his lower spine. Leaving a blodied body on the ground. Coffee from the smashed cups merged with his blood. Little did anyone know that day would be the birth of a new hero.
He,he,he he is the COFFEE BOY,
Fighting the evil villain Sleep Deprivation day and night, but mostly night. And his sidekick Mugatron always covering for Coffee Boy !!! -
Am I an asshole for not wanting to learn infrastructure/AWS?
im sure it isnt rocket science, but somewhere from within, even if I try my body rejects it will every fibre of its being
manual bare metal servers, deployment scripts and firewalls? sure im all in
Containers, k8s tied to nginx on the said server? sure
Entire end to end as long as it doesnt involve AWS? done and dusted
But add AWS/Azure to the mix and I'm oil to water 😪7 -
me: this installation needs swap space on server
ops: we don't do swap space on AWS
me: ಠ_ಠ OK, what other solution can you provide me?
ops: here, use this real (bare metal) server we have
me: will it have all the same access and installed packages I had used on the AWS server?
ops: no, you need to create tickets for that
me: ಠ_ಠ -
I'm wondering if I should buy a ~1800usd/year bare-metal server to put ALL my random websites/projects/app-backends, instead of buying VPSes here and there
But the thought "all eggs in 1 basket" is kinda scary -.-
And no, buying a static IP and hooking it to a home-server ain't happening (unfortunately), coz I move around a lot9
