There is. My latest creation. A 8bit microcontroler made in minecraft.
Features:
(1.0 version without control room)
-8bit full adder + overflow flag
-8x8bit RAM
-16x8(4bit instruction, 4bit address)
program memory
-64 possible microinstructions (16 instructions with 4 step each)
-uncondintional and if oveflow jumps
(place determined using address written with instruction)
-1/3Hz clock speed 😨
New working version (2.0) has 1Hz clock and new faster instruction decoder.
In 3.0 in addition to that useless bus was replaced with 16x8bit "hardware" stack that can store adresses and data. The clock is going to be yeeted out because it is unnecesary #clocklessisbetter (WIP tho)
Might add more documentation and post it as learning model for CS wanabees 🤔. What do you think?

About two years ago I get roped into a something when someone was requesting an $8000 laptop to run an "program" that they wrote in Excel to pull data from our mainframe.
In reality they are using our normal application that interacts with the mainframe and screen scrapping it to populate several Excel spreadsheets.
So this guy kept saying that he needed the expensive laptop because he needed the extra RAM and processing power for his application. At the time we only supported 32 bit Windows 7 so even though I told him ten times that the OS wouldn't recognize more than 3.5 GB of RAM he kept saying that increasing the RAM would fix his problem. I also explained that even if we installed the 64 bit OS we didn't have approval for the 64 bit applications.
So we looked at the code and we found that rather than reusing the same workbook he was opening a new instance of a workbook during each iteration of his loop and then not closing or disposing of them. So he was running out of memory due to never disposing of anything.
Even better than all of that, he wanted a faster processor to speed up the processing, but he had about 5 seconds of thread sleeps in each loop so that the place he was screen scrapping from would have time to load. So it wouldn't matter how fast the processor was, in the end there were sleeps and waits in there hard coded to slow down the app. And the guy didn't understand that a faster processor wouldn't have made a difference.
The worst thing is a "dev" that thinks they know what they are doing but they don't have a clue.7 -
Friend: I bought a new phone.
Me: nice!
Friend: It's really fast coz it has 3gb ram!!
Me: okay... Other specs? Cpu? Camera?
Friend: 13 MEGAPIXELS!
Me: yeah but other specs?
Friend: doesn't matter! The photos are of 8mb!
Me: yeah. Best phone ever. 😑😓10 -
Use SSDs.
It's not hard. They've been around for a while, small ones are cheap now and are more than enough for at least 90% of developers. The rest can probably afford 2TB NVMe.
Why waste 60$ on a worthless 500GB HDD that will load the OS in the time that's enough for you to make scrambled eggs?
Instead, use 60$ on a 128GB SSD. Sure, it's smaller, but if speed is important for you, you can forget a bit about saving all of the porn you see online, or about installing every free game from Steam.
SSDs are cheap already. And the performance advantage they give is ENORMOUS. You can have a core i9, 64GB of fastest RAM bla bla bla, but if you don't have an SSD, a Celeron with an SSD will seem faster.
Get one, and NEVER again cry about long loading times of IDEs, unless you feel like 30 seconds for the longest load time is too much. If your time is THAT valuable, then you can afford NVMe SSDs in RAID 10 (which can be done easily in software with btrfs if you're on Linux).
Seriously!
Every day I see posts like "Visual Studio is crap because it installs for 6 hours", or "Android studio starts in 30 minutes", or "Visual Studio Code sucks because it loads for too long compared to vim".
It's as if you only have access to budget 10 year old computers.27 -
!rant but history
I found this old micro controller: The TMS 1000 (from 1974). The specs: 100-400kHz clock speed, 4-bit architecture, 1kB ROM and 32 bytes (!) RAM. According to data sheet, you sent the program to TI and they gave you a programmed controller back - updates to the once upload program were impossible, but an external memory chip was possible.
I'm glad we have computers with more processing power and storage (and other languages than assembler) - on the other hand it enforced good debugging before deployment and and efficient code.

Can someone help me understand?
I subscribed to a nifty IT-releated magazine, and on its back, there's an ad for "Dedicated root server hosting", nothing unusual at a first glance, but after I read the issue, I decided to humor them and see what it is that they offered, and... It just... Doesn't make sense to me!
An ad for "Dedicated Root Server" - What is a dedicated root server first of all? Root servers of any infrastructure sound pretty important.
But, the ad also boasts "High speed performance with the new Intel Core i9-9900K octa-core processor", that's the first weird thing.
Why would anyone responsible enough want to put an i9 into a highly-reliable root server, when the thing doesn't even support ECC? Also, come on, octa-core isn't much, I deal with servers that have anywhere between 2 and 24 cores. 8 isn't exactly a win, even if it has a higher per-core clock.
Oh, also, further down the ad has a list of, seeming, advantages/specs of the servers, they proclaim that the CPU "incl. Hyper-Threading-Technology"... Isn't that... Standard when it comes to servers? I have never seen a server without hyperthreading so far at my job.
"64 GBs of DDR4 RAM" - Fair enough, 64 gigs is a good amount, but... Again, its not ECC, something I would never put into a server.
"2 x 8 TB SATA Enterprise Hard Drive 7200 rpm" - Heh, "enterprise hard drive", another cheap marketing word, would impress me more if they mentioned an actual brand/model, but I'll bite, and say that at least the 7200 rpm is better than I expected.
"100 GBs of Backup Space" - That's... Really, really little. I've dealt with clients who's single database backup is larger than that. Especially with 2x8 TB HDD (Even accounting for software raids on top)
This one cracks me up - "Traffic unlimited"
Whaaaat?! You are not gonna give me a limit to the total transferred traffic to the internet for my server in your data center? Oh, how generous of you, only, the other case would make the server just an expensive paperweight! I thought this ad was for semi-professionals at least, so why mention traffic, and not bandwidth, the thing that matters much more when it comes to servers? How big of a bandwidth do I get? Don't tell me you use dialup for your "Dedicated Root Server"s!
"Location Germany or Finland" - Fair enough, geolocation can matter when it comes to latency.
"No minimum contract" - Oooh, how kiiiind of you, again, you are not gonna charge me extra for using the server only as long as I pay? How nice!
"Setup Fee £60" - I guess, fair enough, the server is not gonna set itself up, only...
The whole ad is for "monthly from £55.50", that's quite the large fee for setup.
Oh, and a cherry on top, the tiny print on the bottom mentions: "All prices exclude VAT and are a subject to..." blah blah blah.
Really? I thought that this sort of almost customer deceipt is present only in the common people's sphere!
I must say, there's being unimpressed, and then... There's this. Why, just... Why? Anyone understands this? Because I don't...12 -
Recep Tayyip Erdogan had a problem — after his army service, he got so used to cold that he could only sleep on a raw, cold metal grill. Usually, normal people put mattress on top, but Erdogan didn’t feel right this way. So, in one of his personal prisons, he established a social project for making a full metal bed for himself.
For starters, to calculate the shape, he took the smallest man ever (3 inches high) with his fingers and sunk him into molten plastic. “What are you doing?! It hurts!” — man screamed. “Shut up. You’re on an important mission. Your motherland won’t forget you.”
After three months, the bed was ready. It was more of the same — metal bars, but this time with some kind of structure built of metal hinges, rebar and strong springs. This was the day — this was the big reveal event. It took place in the same prison — three prisoners were ready to lay on their new full metal beds, while news crews congratulated Erdogan and celebrated his greatness. “Well, it is time!” — he said.
Prisoners laid flat. An awful screeching sound. Prisoner number two is bleeding out. The spring mechanism broke out and impaled his chest onto a large metal bar. He’s not breathing.
“Shut it down. Shut it all down. No more cameras, no more news”, — said Erdogan.
“Yes, our master”, — said news crews.
They wanted to draft me to Afghanistan.
“No!”, — a young officer shouted, misgendering me — “He doesn’t know the stages of pain. Useless.”
“Are you perhaps arguing pain with a bipolar patient?” — I replied.
“You are a rave. Nothing but a rave.”
Raves spawned near your doors at night. Sometimes, they even spawned on the inside. I can’t say you were in danger, but it certainly wasn’t a pleasant thing to happen to anyone. They looked ugly. They dressed weird. They spoke in riddles.
“How do I move to Europe?”, — a rave asked.
“I…”
“Shut up!”
Rave took a door, suspiciously painted over and over multiple times, and started to slam my door with it, using it as a ram.
My door started giving in.
Alarm system.
On a separate note, to disable the alarm system, you have to speedrun Stanley Parable. It’s the hardest speedrun ever, specifically its hidden ending. It disables all alarm systems in three-mile radius IRL. No one knows how it works, but it does. Back to the danger zone!
“The better quality time you spend sitting on your toilet, the more you’ll live.”, — an officer said.
“I once had a girl blow me while I was shitting,” — Matthias replied — “You have nothing on me.”
“Fair enough!”
It is a little known fact, but the liquid that Northern cities use to clean up snow isn’t quite what it seems like. It’s not salt — in reality, there are bases on Mars, and they store pink goo that… “iMpRoVeS” dead bodies. The liquid is biological in nature, and it expires. Expired liquid is recycled as snow melter. You learn that in high school, but now, living on a train, you should know that there are special learning rooms here, in every. single. carriage. The small gym ball with two handles on its sides is called Gandhi ball. Fun fact: if you wear headless Segways on top of your shoes, and then lay flat holding a Gandhi ball, you can reach the speed of 270 kph!

This shit is long story of my computer experience over my lifetime.
When I was young I got my first PC with windows it was not so bad. It required safe shut down of it’s fat32 partition. From time to time I needed to reinstall it cause of slow down but I got used to it I was only a gamer.
Time passes and I got more curious about computers and about this linux. Everything worked there but installation of anything was complete madness and none of windows programs worked well, and I wanted to play games and be productive so I sticked with windows.
I bought hp laptop once with nvidia card, it was overheating and got broken. So I bought toshiba and all I told to the seller was I want ATI card. Took me 5 minutes to do it and I was faster then my friend buying pack of cigarettes because I was earning money using computer.
Then I grown up running my small one person programming businesses and I wanted to run and compile every fucking program on this world. I wanted linux shell commands. I wanted package manager, and I wanted my os to be simple because I wasn’t earning money by using my os but by programming. So after getting my paycheck I bought mac. I can run windows and linux on vm if I need it. I try not to steal someones work so I didn’t want to run hackintosh. I am using this mac for some time.
Also I use playstation for gaming. Because I only want to run and play game I am not excited about graphics but gameplay. I think I am pragmatic person.
I can tell you something about my mac.
When I close lid it go sleep when I open it wakes up instantly. I never need to wonder if I want to hibernate or shut down or sleep and drain battery. It is fucking simple.
When I want to run or open something it doesn’t want me to wait but it gives me my intellij or terminal or another browser or whatever I search for. Yeah search is something that works.
Despite it got 8 gigs of ram I can run whatever number of programs I want at the same speed. The speed is not very fast sometimes but it’s constant fast.
I have a keychain so my passwords are in one place I can slow down shared internet speed, I can put my wifi in monitor mode and I don’t need to install some 3rd party software.
And now I updated my mac to high sierra, cause it’s free and I want to play with ios compilation. Before I did it I didn’t even backup whole work. I just used time machine and regular backups. And guess what, it still works at the same speed and all I did was click to run update and cook something to eat.
When I got bored I close the lid, when got idea open lid and code shit, not waiting for fucking wakeup or fucking updates.
I wanted to rant apple products I use but they work, they got fucking updates all along at the same time. And all of updates are optional.
I cannot tell that about all apple products but about products I use.
I think I just got old and started to praise my limited time on this world. Not being excited about new crap. When I buy something I choose wisely. I bought iPhone. I can buy latest iPhone x but I bought iPhone 7 cause it’s from fucking metal. And I know that metal is harder then glass, why the fucking apple forgot about it? I don’t know.
I know that I am clumsy and drop stuff. Dropped my phone at least 100 times and nothing.
I am not a apple fan boy I won’t buy mac with this glowing shit above keyboard that would got me blind at night.
I buy something when I know that it can save my time on this world. I try to buy things that make me productive and don’t break after a year.
So now piece of advise, stop wasting your time, buy and update wisely, wait a week or a month or a year when more people buy shit and buy what’s not broken. And if something’s broken rant this shit so next customer can be smarter.

> wait, what do you mean new motherboards are $300? Wait.
> Wait, no, how is the one Ryzen motherboard under $100 a shit B450M on sale? The fuck are these prices?
TIL motherboards are volatile as fuck on price. In fact, mobos are less stable in value than most crypto.
Jesus fuck.
(The one B450M i saw is actually now $140-some and a nice X570 is currently $120. Why does the price of these fuckers change *daily?*)
as for case none under $100 are good so i picked some random mostly-mesh ATX mid case over my preferred ATX full case and i'm just gonna pray i can find some fan config that works because at this point i'm done with this shit fuck this, a bottom-barrel mobo, low-tier cpu and a decent case shouldn't be $400 or more12
