Flying a simulated spacecraft controlled by a ZX Spectrum and Sinclair BASIC my first computer and programming language. Terribly inefficient right now because the serial port is so slow and the CPU spends lots of cycles bit banging to talk to it. There's a Python program in between which... show more

Did you know that many C64 and ZX Spectrum games were developed on a Tatung Einstein computer? The Tatung was used to edit/assemble and deploy the code to the target machine via a serial/parallel link. Here's the editor in action loading Bubble Bobble source code for the Spectrum

This is a Commodore 1541 5.25" floppy disk drive. It functions as a computer in its own right, with its own 8-bit CPU, ROM, and operating system (CBM DOS). It is its own computer with its own operating system. The Commodore 64 or 128 or Vic 20 or whatever would talk to it over a serial cable and send commands to the onboard computer. These drives were so robust and overbuilt.

My 8080 CPU simulation in 74-series logic can now boot CP/M (floppies simulated over a serial line) and run Zork. At a simulated 25KHz instead of 2.5MHz as a real CPU does it takes over 7 minutes to boot and start playing. (Video mostly sped up to 20x)

#WATCH | Delhi | In response to ANI's question on Chabahar Port, Iranian Foreign Minister Abbas Araghchi says, "Chabahar port is one of the symbols of cooperation between Iran and India. We are so glad that Indians played an important role in the development of that port. It is now somehow slowed down because of the US sanctions. But I am confident that this port would be like a golden gate for India to access Central Asia, the Caucasus and then Europe through this transit route and also for Europeans, Central Asians and others to access the Indian Ocean... I hope that Indians would continue their work in Chabahar port so it would be fully developed at the service of the interests of India and other countries around. I think India, with its good reputation, can play a greater role in this region to help diplomacy and to promote peace and security. India is a friend to all countries in the Persian Gulf... We appreciate any positive constructive role played by India in this region."

ASSIMETRY for ZX Spectrum (by MANU & KIT, 2025) Very cool side-scroller/run and gun game. Was part of YRGB, a game development competition for the ZX Spectrum computer, where it got 1st place in graphics and 2nd place overall. ℹ️ #ZXReposts #gamedev #8bit

“Spectrum is its own commodity race…you have fights brewing in Washington around what spectrum is going to be put up for auction to the private sector, and what spectrum is going to be held on to by government. Connectivity enabled by spectrum is in higher demand right now.”

🖨️ It took over a year and lots of help from Claude Code but I have now been able to create a real dot matrix printer on the web that prints from Windows 3.11 in your browser: Here's the test page: I couldn't get the LPT1 port to work but COM2 did work (the dial up model already uses COM1), the JS receives the COM2 serial data (just raw print data) and then prints it Next is to make the dot matrix printer better looking (kinda 3d like on pieter dot com) and have the paper also flowing in 3d out of the printer and integrate it on the page My idea was that it might work because we also capture the COM1 data (from the dial up modem) and send it to a Websocket as a dial up connection, so we should be able to capture the COM2 traffic too but I didn't know how, but now I do IT WORKS!! 😊

I did a quick and dirty port of some python Asteroids code to adapt it to my USB->HP bridge, and here it is displaying on the HP1345 vector monitor!

Jensen Huang built the world's most valuable chip company and is telling the next generation of programmers prompt engineering is the future: "Why program in Python? So weird." "The first time I talk to the computer, I'm just speaking in plain English." "English, by the way, human, it's the best programming language of the future." "How do you make a computer do what you want it to do? How do you fine tune the instructions with that computer? That's called prompt engineering. There's an artistry to that." PS.

A Moment for history. Yesterday we did a single port lobectomy on a patient 8,000 km away, from China to Romania. This is the first transcontinental thoracic surgery in history, the first telesurgery from Asia to Europe and the first single-port robotic transcontinental surgery

Most C Programmers don't have a clue as to how the CPU works. Here is a lecture from my course on the C Language that introduces how to visualise the CPU as a C (or general software) Programmer.... More Details are at: Being able to model the behaviour of CPU provides a solid base to reason about your code. The summary is - - The CPU is a state machine which maintains it's states in registers. - It has busses to memory for requesting data/instruction read/writes. - Interrupts to attend to events. I discuss this and more in my course on the C Language.

Commissioner of the port of Seattle: I'm looking out at the port of Seattle right now, and we currently have no container ships at berth. And that happens every once in a while in normal times. But it is pretty rare. And so to see it tonight is, I think, a stark reminder that the impacts of the tariffs have real implications

🚨Iran’s Chabahar Port VITAL for the global south, India’s🇮🇳 PM Modi may be the ONLY ONE capable of bringing peace to the region ‘The US or Israelis have attacked not only the Bandar Abbas Port, there has been attack on the Kharg island which happens to be quite an important port for energy exports. Now Chabahar Port will definitely play an important role, but there is ambiguity towards that. India was working on developing the Chabahar Port. Given the recent political issues, there has been a slowdown on the development of Chabahar Port. So whether that will be reactivated by India, that needs to be seen. 85% of the exports from that region is catered to the Global South. So it’s not only India that will benefit, the entire Global South will benefit out of this. Iran has been under embargo and sanctions for decades now. India has taken the initiative to develop that port, and they have achieved considerable success in that, and they wanted to move forward on that. However, in the recent past we have seen that there had been a slowdown. We feel that India should relook into activating that port, and to bring sanity, as that could be part of one of the peace talks. As far as BRICS is concerned, BRICS has become a very strong body. The next BRICS meeting is in a couple of months, so they may play a very important role to bring sanity in this region. The Global South should stand up to this and find sanity. There has been talk that the Prime Minister of India is perhaps the only person who can bring peace to this region. The Israelis have said they don’t want to accept Pakistanis as a mediator. So the world may have to go back to India, to Prime Minister Modi. Whether he’ll accept or not accept, that remains to be seen. But for the sanity of the world, probably he may have to look at that positively and come forward for peace.’ -Dr. S. V. Anchan, Chairman of the Safesea Group, which owns the Safesea Vishnu which was attacked by the IRGC Watch the full interview in the quoted post below👇

Will Cogley designed a highly bionic robotic head for a humanoid robot called the Stewart Platform Neck, demonstrating the ultimate pursuit of fine facial expressions and head posture control, which is inspiring for more realistic human-computer interaction in the future. The Stewart Platform consists of six linear actuators connecting two plates to achieve six degrees of freedom, simulating the complex structure of human neck muscles. It is controlled by Python programming and inverse kinematics algorithms, and supplemented by a 3D printed flexible spine to provide support and flexibility.
