RFSoC is an fpga with high speed ADCs and DACs integrated, 8 5Gsps ADC, and 16 10 GSPS DACs in a single device, and less than 1000 bucks IIRC, though not sure on volume (i.e. If you can buy single parts)

And try have meeting free zones. 8 half hour meetings spread over a day is nearly as bad as 8 hour meetings in terms of getting work done, 30 mins gaps only allows for easy tasks (email, etc), but not true engineering/deeper work.

What's particularly lacking in the MS interior? Very comfortable, leather all round, heated and adjustable seats. Best infotainment/nav system hands down, glass panoramic roof, and a very clean look.

If you leave the self driving aside, the model s is an amazing car. Compared with a high end bmw/merc/audi you get more features as standard - though I do admit the finish/build quality on those cars is superior. I have a 4 y

I did think it was imminent at one point, but the fact the delivery date keeps pushing out shows its far from complete, and is only usable in controlled circumstances. I use it in traffic jams, or motorway driving, and that's it, anywh

That rate sounds too high. Typically scan test gives 99.9% logic coverage. This me as random defects must hit this exact subset of logic to cause a fault undetectable by production test. Given defect rates are low, 1 in 1000 having a fault

There was a big hack recently in Ireland that had taken out the health service IT systems, with a ransom demand. The entry point there was what seems like social engineering, they got an employee to call a number from a Web popup claiming t

I've a Dell precision 5530 for work, absolutley roasting, continuously, even under no load. It's so bad, I'm switching to a mac book pro 16. Seems like out of the frying pan and into the fire for me!

That's brilliant, congrats. Typing on a terminal of a machine you built from scratch must be so satisfying. I like that this runs an OS also, as many home brew CPUs run much simpler SW.

Nice project. Reading through some of the gotchas is interesting, though one stood out - the RT related gltich. Having some combinatioral logic control a reset is in general a no-no, for exactly this reason, a race can happen and combo logi

Airgapping critical functions needs to be a thing. Infotainment that's online should be no where near driving, safety or engine management functions. If those fictions require an OTA update, then it could be done by enabing a physical

This is the same thing that happens to so many companies, and I blame Wall Street, and the growth at all costs mentality. We all know rationally that continuous growth is impossible, yet its what wallstreet and bean counters demand. Cadbury

I think the shift in culture is directly correlated to being better off for the average person. Dublin is very different from rural places, that have changed more slowly. Its modernisation, for better or worse. Politics is as crooked as eve

Having large multinational corporations is hugely beneficial to the Irish economy, through direct employment. Sure any company that is just a brass plaque and funneling money through Ireland is of no benefit, but most of the big ones have s

I agree. We're inundated with wellbeing emails and events, and while I appreciate the effort, it is just a token as only the lucky few with spare time can go to these things. When the balance is way off, taking more time for such meeti

Thanks, though I'm not sure all compile time detectable undefined behaviours is exposed through warnings today. In the example in the article, why would something like left shift of a -ve value require runtime detection, surely the fac

by tails4e 5y ago
Sorry for my ignorance, but surely some UB being used for optimization by the compiler is compile time only. This is the part that should default on. Runtime detection is a different thing entirely, but compile time is a no brainer.

Changing gcc version could cause your code with undefined behaviour to change. If you rely UB, whether you know you are or not, you are in for a bad time. Ubsan at least let's you know if your code is robust, or a ticking time bomb...

by tails4e 5y ago
Ubsan should default on. If people don't like it, then they should be made turn it off with a switch, so at least it's more likely to be run than not run. Could save a huge amount of time debugging when compilers or architecture c

Interesting fact, the term tape out comes from the way chips were physically laid out back in the early days. The chip layout was manually arranged using pieces of coloured tape on a large workspace/table. Once complete, this was photo

Is the resolution of the images off? In my area where recent images have decent resolution, all images in time-lapse mode are very low res, including ones from. 2016, 2020.

Exactly, this is disingenuous to say the least. To measure the danger a drug poses it should be comparing the drugs effect per user, not multipied by how popular it is, or at least show both charts together to remove any doubt.

While I love the amazing engineering that goes into getting a helicopter onto Mars, the pace things are tried at is frustratingly slow. While I'm sure in part it's to ensure nothing goes wrong/not risk it, can someone specula

A HW startup will not be suddenly successful because of their EDA flow. They could however fail badly if they have their EDA incorrectly setup, as if your chip STA flow was incorrect and you have hold time issues on silicon, you just blew 6

Yes and no, if a startup has experienced designers, they can work around issues. I've often done this and I have access to AEs, as to get an issue resolved externally takes more time than a bit of debug on why the tool is not doing wha

The EDA tools are often given for almost free to startups, as the vendors recognise startups can't start without them, and if they are too expensive to a fledgling company they are shooting themselves in the foot. Startups get the tool

I'm curious about this. It seemed to be alot of 'work' just to get arguments. While I could read the code with no prior experience, there were enough unexpectedly verbos things in there that suggested it could take a consider

Nice, I have the xaoimi mi vaccum Mop, not sure it's supported by that site just yet, but glad someone has taken up the challenge. It's a great little device.
