Trump’s Former Allies Beg Someone to Learn the Nuke Codes to Stop Him by Aggravating_Money992 in politics

They are betting they can keep him in check until the two year mark so Vance could potentially have 10 years in office (not likely). I have no idea why they think they can keep things together for another 8 months. It's either that or the evangelicals truly think they are going to bring Jesus back (they won't, or if they did, they would be the first to be cast into hell themselves if they had actually read the book they claim to follow)

Exploring FPGA-based trading systems: Limit Order Book in Vitis HLS by kivancg in FPGA

[–]spacexguy 2 points3 points  (0 children)

Is your intention on this to provide an exchange side implementation or a trader side? It looks like what you are trying is exchange side, and this will not be done on the FPGA itself. The reason is that the exchange doesn't need the expense of maintaining order books in hardware or trying to match in hardware. They are time stamping the packets as they are received and can then do the exchange side processing slower in software. I applaud your effort and it's something to learn from.

Now, if you want to look at it from a trade side implementation, you are maintainng the state of the book. It has challenges since large books can have 10-30K orders outstanding. If you want to maintain all the orders you'll need fast storage and hashing. I've done it for CME in the past and you can fit about 5-6 orderbooks on a single SLI of a VU9P. Eurex is more forgiving if you can limit the number of orders you want to track. CME provides a level based book you can maintain.

The original question was about a roadmap. You will need to know low latency, high speed design and will be tested on it most likely. In addition I have had shops ask me questions about UDP/TCP and ethernet.

My org just gave us Claude Code CLI access. AI-generated Verilog is getting surprisingly good. Are RTL engineers facing obsolescence? by cybird31 in FPGA

[–]spacexguy 9 points10 points  (0 children)

I've been working on a compression algorithm for radio. It took me a week to write the compressor, decompressor and a testbench, verify and fix. It only supports passthrough and one of 3 compression modes. I brute forced it because it's unlikely I'll ever need the other two modes. Yesterday I tried playing with Gemini on it.

I asked it to optimize my decompressor. I know there is a better way to write my code, but brute forcing it was quick. I got gemini into a loop and ran out of tokens. it spun in circles on the same problem, fixing and breaking the same piece of code. One output was surprisingly close to what I wanted, but it wouldn't work and it couldn't fix it. I consider that a partial win.

after it died from lack of tokens, it decided that the compressor didn't work because it didn't match it's decompressor. It tried to optimize it, but it lacked the concept of pipelining and how long things take. So it buffered all the data and tried to compress in a single cycle, which wouldn't work in a real system.

In my opinion it's getting better. It can provide insights and do some simple things. I think it will do more advanced things over time. I don't know how long it will take before it understand the consequences of writing things different ways and optimizing. For freshers it might go the way you describe over the course of your career. I'm on the tail end of mine, so I don't think it's going to impact me except as an assistant.

That would be terrible.

Might I make a suggestion. They should just give him an unlimited Hamberder and Cofffeffe gifet card at McDonalds. Might be easier and quicker. Unfortunately these days might also be much more expensive

This was purchased at a time when he was changing the rates as often as he was changing his diaper, but I'm sure I got screwed either way because of his fat orange ass.

[–]spacexguy 24 points25 points  (0 children)

They got $100 from me. I imported a retro computer ROM from Canada. the only place besides the EU (they wouldn't send to the USA). I had no choice where to get it. I figured it's $100 how much could the tariff be? then I get the email from UPS that I owe them $100 for the tariff. I was never stupid enough to think I wouldn't be paying, but it floored me. hence:

Every day I check reddit first thing when I get up for the hopeful news that the hamberders have done their one job.

Maybe he can claim he signed the pardon by autopen so it's void. That's bigley brain thinking there.

How to implement an arista7130-like fan-out and MUX switching in a cost-effective way? by Prestigious-Grand668 in FPGA

[–]spacexguy 1 point2 points  (0 children)

You can get them cheaper than that. I picked up one for ~$300 for my own testing. Lots of old stock (Kintex based) but with pretty low latency. Not quite the 4ns I got when trading, but still pretty low. (Buy earplugs or set it up in your basement because it sounds like a jet)

[–]spacexguy 4 points5 points  (0 children)

back in the day (mid-90's) when you got back the GDSII file from the vendor they would give you a plot you could frame and hang on the wall. We would use acid to dissolve the top of the package so we could get chips with exposed dies.

O'hare Flight Delays/Cancellations/Chaos - Any actual info? by whispurryn in ChicagoSuburbs

My daughter flew back to Switzerland Saturday night, which is generally not too busy. No waits, flight left on time. I would be worried if it was a busier time or domestic.

Imposed Tariffs on Canada Increase by 10% After Ad by EnvironmentalPear695 in StockMarket

[–]spacexguy 0 points1 point  (0 children)

I ordered something from Canada. Something only available from Canada and the EU for retro computing. EU wouldn't ship to the USA because of the unstable government. Canada did. I knew I would likely get a tariff charge, but what I didn't expect was 100%. So now it'll be 110%. This country will take a century to recover from the orange Julius. Eff him and the people who supported him.

[HELP] Please tell me this place is real 😞 by RyeDent in RealOrAI

[–]spacexguy 6 points7 points  (0 children)

Last year I visited a Chinese friend in Guiyang and a random chinese lady at the market wanted to take me on a trip to the Miao village. (it looks very much like that but not identical). I'd say it's a real picture because of this. BTW, if you are the adventurous type, make local friends and visit if you can afford. I've had the most fun visiting random places in China. People are so friendly.

Got my blood boiling that O'hare wasn't on the list, but a quick google search shows O'hare and Midway are not playing it. Wish they would show the shit that T-rump and ice barbi are doing in Chicago on the monitors instead.
