Just some experiences with chatGPT and VHDL. I had asked chatGPT to create a template for a testbench with a component with specified signals. It did a pretty good job creating the template, including inferring that some of signals were clocks and creating square waves for them automatically...

No OS? No problem! ChatGPT can emulate a linux shell for you. It can emulate lynx for you. It can emulate python for you. It can even emulate YOU for you (ok maybe it cant do that, not sure yet). https://www.engraved.blog/author/jonas/ Some of the comments are also interesting.

It's been a few months since the AMD 6900hs 6800hs mobile cpu release, but I'm not seeing many laptop options. edit: See links below, I'm starting to see more options, with some better prices than before.

I have 2 4-pin fan outputs from system. I need to either to limit the duty cycle to some max value, or to adjust the duty cycle to limit the tach to some max value. I don't care which. The tach from each fan MUST come back to the 4-pin fan output from the system (I need the system to still...

This is not strictly networking. Please feel free to move it if this is the wrong place. I need ideas Small company I work for has most of their tech infrastructure in-house (email server, smb share, etc etc). We need to move it into the "cloud" so that employees can work remotely from home...

If this post looks familiar it's because I have this same post posted at anandtech Say I have a webserver that is unfixably insecure and is on my local network. What I mean is that if an intruder was determined and had network access to the webserver he could exploit the machine like crazy, and...

I am not a fan of screen tearing. Screen tearing is caused when the video frame buffer and the screen refresh rate are not synced correctly. The monitor draws pixels on the screen left to right, going down each row, the same order as when you read a book, from the video buffer. So...

1)There are 100 prisoners in solitary cells. There's a central living room with one light bulb; this bulb is initially off. No prisoner can see the light bulb from his or her own cell. Everyday, the warden picks a prisoner equally at random, and that prisoner visits the living room. While there...

I have this issue, and i have read the manual and played around with this reciever but i wanna see if you guys have any feedback for me. I got an onkyo tx-sr500 reciever and i have a 5 satellites and an active sub hooked up to it. I am currently just using my onboard realtek sound via analog...

I understand the concept of polarity, but I wasn't sure how to actually detect which setting would be correct to use. I recently got a subwoofer that has a button for normal or reverse polarity. I know i stayed consistent with my wiring between satellites, but i don't know if all of them are...

I've been researching some blue screen issues some computers were having regarding storage drivers and i came across these 3 drivers: iastor iastorV msahci 1) Do amd chipsets use msahci or yet a another driver? amd_sata.sys, is that it? 2) is msahci just a microsoft generic ahci driver...

So i'm hearing about these tv's that dynamically "upconvert" 2d movies to 3d. Do you guys know how this technology works? I can't even begin to comprehend how a tv can dynamically extract any depth information from a 2d movie. I've heard this is a gimmick, but I wonder how "smart" the...

Stop Online Piracy Act What is the SOPA bill? What are the pros and cons of it? Also, why are so many people against it? I tried reading the actual bill, and it seemed to only reference dns and internet providers in fighting piracy specifically. It doesn't seem like the bill has any...

Do standard hard drive diagnostics tell you anything on ssd's? I can't find much information on this topic, except for some post on the internet somewhere where someone simply said that standard tests do not work at all on ssd's. I can see how a test that tells you your drive is fine may...

Do you guys know how much space (i dont know, measured in percentage of transistors i guess?) is kept alive on modern processors for legacy instructions, How much of the x86-64 processors exists to keep it backwards compatable with all x86 code? For example, is x86 real mode really used for...

looking for some new speakers for a friend for around 150$. I can get the klipsh media 2.1 system for 90$, anyone have experience with these speakers? Otherwise i can get the m-audio av40's for 120$, but i think my friend would appreciate the extra bass more than the clarity of the...

so I've been obsessed with passive cooling for a while now (i keep researching builds for completely passive setups). Anyways, while i am obssessed with the idea, I don't feel like it would be that satisfying to just start dropping 600$ on a computer i dont actually need. Recently, i recieved...
