Calling all COBOL geeks........ I have never used COBOL. I wonder about the latest claims of waste fraud and abuse made by Trump/Musk about 150 yr old recipients of government largesse. Talking heads claim that, in fact, COBOL actually defaults birthdates to 1875 as an error code . I would...

I use ChatGPT at this point as basically my personal tutor. It has been a huge help in learning Python code, fixing issues when I'd have them, verify it's working as intended, etc. Also helped me with some of my problems in other classes too (it's difficult for me to make it to office hours a...

I have a masters degree in computer science. I spent 5 years in the army, with two years in Vietnam. I spent most of my career in the manufacturing sector of the economy utilizing my analysis skills.

Hello! So, my answer is off by one from the answer sheet to this question. I can not spot where and nor can online friendly chatbots. Here is the question: And here is the answer key: I have problems in specifically the CPI question. I am correct with the other questions (data/instruction...

I'm a marginal computer nerd & electro-mechanical tech.

In 1983, a Yugoslavian engineer created a small computer that gave fellow Yugoslavians a taste of computing that they couldn't get otherwise because of strict import rules. https://www.theguardian.com/games/2024/oct/24/how-one-engineer-beat-the-ban-on-home-computers-in-socialist-yugoslavia

Hello! I work as a data scientist, computer vision engineer, and computer science engineer. Lastly, but certainly not least, I play music (guitar, piano, cello, while practising extreme vocal) 😁 I received my degree in robotics and mechatronics seven years ago from Bauman Moscow State Technical...

Is anyone else experiencing this, or do I have some problem with my system? Almost every time I wake my computer from sleep mode, Windows springs into action downloading updates and hogging resources, locking out other programs (my browser, mail) for minutes at a time. I base this on the tasks...

This is on my wife's computer, which we bought many months ago but has not been used (much). I am getting this popup. The computer is not running McAfee; it is running BitDefender and Windows Firewall. Task Manager tells me this is Malware nwjs (see background in screenshot). When I ended...

A week ago my Windows 10 laptop overheated and decayed. I bought a new one with Windows 11. The first thing I did was download a video. Ads pop up and I'm often redirected to sleazy sites selling something. That never happened before. This happens with Chrome, Firefox, and DuckDuckGo. I...

Hi, So, PC powered of all the sudden, wont power on. Battery had not been charging when PC was plugged in. So, can I conclude neither battery nor power cord are working well? I guess my options for doing something to have battery recharge are limited, given PC won't power on. Do I have any...

Goal/Background I've taken these courses before(from different college/sources but didn't resonate) So my current career goal is to get into computer graphics industry or research. Open to both game engines or simulation graphics Academic goal is to prepare myself for upcoming Computer...

Hi it's my first post here! I'm in my second year of my degree and looking to replace my computer. The new M-series chips seem like a better deal, however I am nervous that some software that might not be compatible with the ARM architecture. For more context on my workflow I do quite a bit of...

I thought this was a fun and quick video of an engineer giving a tour of their quantum computer. Only about 30 seconds, but it looks well, quite beautiful! The engineer mentioned they achieved milestone 2 which has something to do with size. I also haven't heard of the field "Quantum Metrology"...

I am researching self-learning AI, and one of the most talked of solutions is returning to analog computing. Analog computing uses real time changes in voltage and frequency to run calculations or perform functions. Does anyone have any experience in building electronic analog computers based on...

Hello. I need to ask about my folders. My 26,263 folders became 'date modified' in 8 minutes. I created those folders and I am aware they stood there. I think any human being can't be so quick. It seems that this is a good news bad news scenerio, and the only good reason I can think of for...

For the first part, I have used a= 2, b = eps/2, c = eps/2 which I believe works and I have tested it in MATLAB however haven't had any luck reproducing the second part in MATLAB with any numbers. Any hints? Thanks

I am currently a final-year undergraduate student whose primary major is Physics. I double major in Computer Science, and my grade is currently near-top in my department from a prestigious university (non-US, top in my country). My research experience during undergrad has primarily been about...

I know that this expression evaluates to 1 when a is equal to 0. Also for when a is equal to 1/n when n is a positive number, but I'm confused about how to go about this in double precision?

Hello, I an clear on how the modulo operator ##%##, also called the remainder operator, is used in programming. It gives the remainder of the integer division. For example, ##5 % 2 = 1## because the divisor 2 fits 2 wholly times into the dividend 5 leaving behind a reminder of 1. ## 6% 3 =0##...

I have a question regarding the storage capacity of quantum computers. I read that 32 qubits (4 "quantum bytes" if you will - not sure if that's an actual term or not yet) can store the equivalent of 500mb of data. Is this directly proportional? I.e., would 8 qubits store the equivalent of...

I am currently in my final year of high school in India, and slightly confused as to which course I should take. I've always been interested in physics, and would eventually like to do research in quantum computing. I'm not sure whether to take a B.S. in Physics, or engineering (a BTech) in...

I'm 27 and I'm currently attending an online university for compsci. I did the math recently and I won't get my degree until I'm almost 30. Is it still possible for me to find jobs once I graduate?

If this is not the correct forum, perhaps someone would be so kind as to move it to a more appropriate one? Thanks. The current trend in computer chip manufacturing is towards making transistors smaller and smaller, so more and more can be packed in a single chip. This has a number of...

My wife just bought a new Dell computer because the HD on her old computer went bad. The computer is a minitower. She is using the old VGA monitor through an HDMI adaptor (using HDMI to VGA cable). Could that be the problem? Occasionally, the monitor screen goes blue and she has to restart...

Im 14 years old and in the future I want to study computer science, I have found the OSSU course, it would be a good start?Thanks

I've been reading Computer Graphics: Principles and Practice by Folly and I've encountered the following paragraph in chapter 1.5. I haven't understood how he got to the result in the following calculation, that if there exists a single 100W light bulb, emitting an order of ## 10^{12} ##...

Hi all, I just finished my undergrad degree in CS. I did reasonably well and would like to pursue a PhD at some point in the next 6 years, however I am not ready to do so immediately. I have taken a job as a software engineer and intend to work there for a year or two to save up some money. I...

A while ago I started writing a quantum computer simulator in order to learn more about quantum computing. It certainly has helped me. The simulator is written in Python and the development was done on a Raspberry Pi 4. It has also been tested on a pc. In order to see it do something useful I...

Hi guys, 1. Most of the design textbooks which I have seen on computer architecture put stress ONLY till the RTL design of computer architecture. But the story of computer system design goes much beyond the RTL description(i.e how RTL design is converted into actual hardware) 2. We begin from...

Firstly, I don't expect there to a single good answer to this question. I've done some googling and it seems there are multiple options, but I am still interested in suggestions and/or what your experiences are. We started using GIT (GITLab) a couple of years ago and it works well when we are...

I am 18 and currently in the middle of taking a gap year from high school to college. I am going to college this fall, and I want to go into college with a better grip on what I want to do than I have now. I absolutely love physics, science, and math. I also have a huge attachment to the idea of...

Computer languages handle the scope of variables in a precise way so that if one symbol, such as "k" is used in different contexts, the program keeps these separate. When sophisticated human beings re-use symbols in writing mathematics, they can keep things straight, but I don't think they...

Consider the following scenario: a space station is put into orbit, which is absurdly well shielded from all sorts of radiation, a.k.a. "a box". You cannot make any effective observation of what the astronaut inside is up to. (This postulate may be implausible, but in the age of "weakly...

Analog computers were the most powerful computers for thousands of years, relegated to obscurity by the digital revolution. This Veritasium video looks at the history of computers and the differences between analog and digital computers.

When I worked for Kantronics, Inc back in the '70s, this was the first computer, the DEC PDP 8, I used to do IC testing after hot & cold temperature soaking, the engineer that could program it with his eyes closed, now works for NASA:

Hi! I am doing some simple observations of different light sources with a simple DIY spectroscope. When I look at a computer screen I see what I believe to be an emission spectrum due to the dark spectrum with emission lines on it. Is this correct? And why does a computer screen emit an...

I've seen Amazon/Fed Ex/etc. drivers fling packages. With Cyber Monday coming up, I'm wondering if it'd be safe to buy a computer and have it mailed/shipped to me vs. buying in person?
