Search - "emulation"
A few years ago when I was still an apple fan boy, friend of mine bragging me about how android is awesome, we were drinking some shots at our local pub and I was starting to get light headed. At one point he showed me so called "terminal emulator" app. I checked it out, and assumed it's an emulation, just like dosbox, so I decided to verify that "rm -rf *"... (the phone was rooted)
The phone shutdown within seconds, I couldn't stop laughing, while my friend was shock that his new phone was longer booting.
Luckily he managed to reflash the ROM. What can I learn from that experience?
1. Don't drink and sudo
2. Don't call your app an emulator if it's the real deal.24
So this shit happened today...
We were asked to implement a functionality on the device that allows it to go to standby mode to save battery power. Once the device enters that state, it can only be woken up by actual bus-network activity, and usually that means connecting a shit-ton of wiring harness and network emulation devices... Before implementing and releasing the device software that does this, we told that fucktard customer how difficult it would be for him to connect to the device without such a setup. He seemed to be fine with it and said rather arrogantly that we should implement the requirement as asked...
Well okay you cock-sucking motherfucker, you'll get exactly what you asked for... We implement the functionality and deliver the software...
Now this pile of shit comes back running his mouth on how the device tears down all its interfaces (to reduce power consumption) and he can't connect to the device anymore.... Well what else were you expecting you dickhead.
To make things worse for me apparently he runs to the manager describing his apparent problem. Both of them come to my desk.. With that fucking Bastard hiding his smugly mug behind the manager's back... He thought he was going to have the upper hand... Well guess what fucked piece of shit, I came prepared... I showed the manager how this was a part of the requirements by throwing that JIRA ID in their faces... The manager seems to understand but this relentless fuck wanted me to implement a "workaround" that would allow him to connect to the device easily... The manager almost had me implement that workaround, when I expose a huge security flaw in doing so. Guess what, now the entire team comes to my desk and start supporting my statement... To make it better they also tell how doing so will violate other requirements...
I've never felt so happy in my entire fucking career, when the entire team stood by me and watched that asshole drag his sorry ass back to his place5
Project i got to work couldn't get worse
2)mathematical model based emulation
3)no proper comments
When the so called "css expert" ask you why you're implementing so many things in @media all and (max-width: 800px) because it "doesn't change anything"
I had to teach him about responsive web design and chrome developer tools mobile emulation...3
I am new to this "vim" thing, should I use the "original" or am I making sins by using vim emulation on VS code ?5
Win 10 on ARM will not make it. Here's why:
- The devices are ridiculously overpriced.
- Performance is abysmal with emulation.
- Native ports are rare because nobody buys the devices.
- MS doesn't get it.
Instead of addressing the chicken and egg problem, MS even fucks up more: Win 10 S, which is usually pre-installed, can only run shit from the app store. Yeah MS, you think just because Apple gets away with this crap, so can you? Newsflash, Windows isn't iOS, and you aren't Apple.
Even VS 2019 doesn't install the ARM toolchains by default. Because, why would MS entice devs to address ARM64 as conveniently as possible?
MS will just keep gawking at Apple like a pig at a clockwork, and Win 10 on ARM will go down like Windows Phone.31
Can any dev's recommend a good windows emulation program that supports x64 applications?
Really want to be able to run Gamemaker studio 2 on Linux but would rather not install a fully fledged VM.
I'm willing to work with a VM but just rather not have a 12GB installation for a 256MB program...39
WHY IS IT SO FUCKIN ABSURDLY HARD TO PUSH BITS/BYTES/ASM ONTO PROCESSOR?
I have bytes that I want ran on the processor. I should:
1. write the bytes to a file
2a. run a single command (starting virtual machine (that installed with no problems (and is somewhat usable out-of-the-box))) that would execute them, OR
2b. run a command that would image those bytes onto (bootable) persistent storage
3b. restart and boot from that storage
But nooo, that's too sensible, too straightforward. Instead I need to write those bytes as a parameter into a c function of "writebytes" or whatever, wrap that function into an actual program, compile the program with gcc, link the program with whatever, whatever the program, build the program, somehow it goes through some NASM/MASM "utilities" too, image the built files into one image, re-image them into hdd image, and WHO THE FUCK KNOWS WHAT ELSE.
I just want... an emulator? probably. something. something which out of the box works in a way that I provide file with bytes, and it just starts executing them in the same way as an empty processor starts executing stuff.
What's so fuckin hard about it? I want the iron here, and I want a byte funnel into that iron, and I want that iron to run the bytes i put into the fuckin funnel.
Fuckin millions of indirection layers. Fuck off. Give me an iron, or a sensible emulation of that iron, and give me the byte funnel, and FUCK THE FUCK AWAY AND LET ME PLAY AROUND.9
Check out my simple universe emulator.
They fight, they have sex and make children, their genes drift and it produces mutations.
Who knows, maybe the entire history of our universe is two seconds in universe N + 1, where some child launched a program like that and it emulated us. We'll never know
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.7
I've been working on an Emscripten emulation layer for a fledgling startup, and it's just a huge bitch. Seriously, Emscripten is the worst designed project I've ever seen. It embeds constants into a js file that it spits out. It turns out you can't fucking run the wasm that Emscripten emits without these magic constants from the js file.
Additionally, all the wasm imports that emscripten specifies are weirdly cased, with apparently no naming convention. They also use some weird, shitty vararg implementation when it already fucking knows exactly how many arguments are going to get passed to an import.
Also, there are a ton of broken things left over from when emscripten compiled to asm.js that they never bothered to replace with features from wasm. God knows how it even works.
Anyone able to link me to some good reading material on compilers, interpreters, emulation and CPU design?
Keen to actually get some of this knowledge under my belt, don't mind if it requires a little investment as long as it isn't written in (fucking) python, preferably C if anyone knows of anything.
Thanks guys! :-D9
TL;DR - an entire emulation of a closed source CMS to develop a theme
The longer version:
We are using a cms that is closed source, and we only have access to frontend files alongside twig files. The CMS is custom built but many aspects are in a very rudimentary state, for example it is nearly impossible to develop locally, we have to use an integrated text editor to code stuff.
So out of frustration, and for my development needs, I decided I would make an emulation based on Symfony 4. Also because my PM was pressing me to optimise our site. I wrote some custom JS to handle everything smoothly, a semi-sass framework and well-structured twig files.
I was also supposed to work with our graphic designer, but she didn't get any alloted time from our pm to work on it...
Now PM asks me to write a specifications document in order to make another company build the new version
I mean wtf, I'm so bored, I can actually enjoy my day by coding, and no, I'm just there to write the specs.
When I told PM I am currently building the new version, she's like "but we didn't validate anything", when she explicitly said I had a green Go to code it a few months back
Instead I have to make prezies and convert them back to PowerPoint because we have computer-illiterate people in the company who aren't flexible to understand simple tools.
Let's hope it won't get useless by Friday (I have a presentation to give, alongside my estimates and project management presentation)1
I'm preparing slides for my "Vim in an IDE world" talk right now. Do you use vim emulation plugins inside Intellij-based or any other IDEs? What do you think about them? What can you recommend to the beginners?12
Integrated vterm package in Emacs, I'm glad having true-and-efficient terminal emulation inside Emacs4
Day #1 on THE other project. Nothing fancy, just setting up my dev env. Got a decent pc with all the required network permissions. And this time I got w10 [last year I was working there on w7 pc via rdp from another w7 laptop. Dont ask...]
of course no localadmin rights to set shit up. Downloaded all the installs, found someone who has admin rights to run them. I even managed to get admin powershell!
Ran all installers, enabled long paths support, env vars, tweak here, tweak there,... Installed git bash to at least have a taste of shell. Decided to try out wsl. Enabled the feature, didnt reboot right away.
Rebooted. 2xclick on ubuntu setup and I get an error claiming wsl is not ebabled. Wtf? Did I do it wrong? I see bash command is there now so I must have done it right. After some googling I found out that even though I can enable wsl, it doesnt work on my version of windows. It's too okd they say. Yeah, tx MS, that's very intuitive and user friendly!
Allright, my hopes to habe a decent sub-os died. Git bash it is :( but I miss tmux soooo much. Then I came across smth that caught my eye. Msys2 it's called. Apparently it's based on cygwin and has a pacman package manager! ´pacman -S tmux´ -- hippee-ka-yay motherfuckers! It's not the best terminal emulation, but it works quite allright and it has tmux. And netcat!
Banished to mouseclickerland still managed to find a good enough shell. Yayy!
So there it is. My first day's ups and downs, disappointments and discoveries.
If you know a better shell I could set up on w10, please, share
N64 emulation possible on Nintendo hardware? Are you SUUUUUUURE???
According to GBATemp:
CPU: Single-core PPC, 729MHz
GPU: 243 MHz single-core
Possible? Yes (always full-speed)
CPUs: 2, Quad-core ARM11 (804MHz), Single-core ARM9 (134MHz)
GPU: 268MHz single-core
CPU: Octa-core (2x Quad-core ARMv8 equivalent), 1.02GHz
GPU: 307.2MHz-768MHz (max. 384MHz when undocked)
Possible? Barely (5FPS or less constant, only half the instruction set possible to implement)
this all makes total fucking sense7
Wish Apple would add Vim emulation to Xcode and never again even think about removing the ESC key.
XVim is buggy and doesn't work with Xcode 9.1
emulation accuracy is important, kids
here's a set of S3&K songs recorded off my 3DS to show why
Recent VM/Emulation Adventures:
The goal was to get TCP/IP and SSH running on whatever weird VM/emulated machine, and connect to the chatroom at chat.tcp.direct successfully.
Longhorn, somewhere late pre-reset: Crashes right after installer begins "Starting Windows", 0x7b from sum-match ISO. Fail.
TempleOS (well, Shrine, but y'know): Dear god. No. No, I am not writing SSH in HolyC myself *fuck that,* fail.
Slackware: oh ffs i gotta use fdisk to partition this damn thing? and it's not even the good fdisk? Oh, wait... it hangs. Fail.
WinME: shockingly, was *fairly* stable... until it hung up WASAPI and the hypervisor two frames into desktop rendering. Fail.
Mac OS 7: First-boot after install, immediate unknown trap. Just works, eh? Fail.
Amiga: After about 85 resets and 7 hours of constant fighting with WinUAE, I finally got TCP/IP working. (Required 10MB of total RAM and an FPU to connect.) Success!
Win98FE: just... PuTTY and done. Easy. (This was the warmup.) Success...
Other people's achievements so far:
- Minecraft using the new QEMU interface mod thing.
- Hacked smart fridge.
- iPhone, from custom initramfs.6
Why do I always get attached to dead/dying platforms 😖😫😭
I mean, I got the PSP Go a mere year before devs dropped support. (Still awesome for emulation because of the physical buttons)
I was really interested in windows phone for a while that I almost bit the bullet and bought it.(you obviously know what happened to the beloved windows phone platform)
And now suddenly a blackberry passport video pops up on my YouTube recommended feed and now I really want one.
The problem is the lack of apps, I was hopeful because it supported android runtime.
Then my hopes were crushed after I knew that its based off KitKat.
Which means one of my favorite apps doesn't work there (my beloved termux, I get a boner whenever I think about using it with an actual keyboard 😂)
Should i just bite the bullet? I'm too broke and that 200$ is kinda of a major purchase for me (I'm 17 in a third world country, so the piggy bank is empty AF)
God, why do I always get introduced to platforms too late...6
Hey, I'm looking for a tool to emulate multiple, maybe around 100 browser clients at the same time, having open the same page at the same time. Every single instance would need a separate IP (VPN/proxy). It should also be sort of ressource friendly(not 100chrome windows/tabs)
Anyone got suggestions on a tool I could use? thanks8
All I want to do is build a robot. ROS is slow as crap on a raspi when you're trying to do SLAM. The chassis isn't big enough for a second raspi, and I can't print a bigger electronics tray until the end of my week off.
Also, Ubuntu just doesn't want to work right on my Surface. Emulation too slow.
So much for building cool things on vacation.
