Re:RepRapMicron on Sunday October 18, 2026 @07:09PM (#50146428)
It’s a fun thought experiment! Napkin maths assuming max 78RPM at 300mm, min 33RPM at 80mm (I think inner groove is bigger than this but wateva) gives ~3 to ~30 microns for half-wavelength of 20kHz (not that 20k is really stamped into vinyl). Actually, not bad.

Amplitude though, 78s are the best case scenario, and assuming mono for simplicity, they have lateral displacement of about 76 microns peak to peak. So assuming 1 micron resolution that’s just over 6 bits of dynamic range absolute best case. Crunchy.

Dodgy maths aside there are lots of reasons this would not produce a good sound. There are maybe clever things you could do with a spinning bed or something? but even then.

At that point though even a normal analogue cutter head will be easier!

I don't. I've been away so long that I may go wrong and lose my way
You could disable Turbo and EIST in the BIOS - most will have a setting for these, and that will result in the cores running at nominal freq.

I don't know about a nice high-level linux interface, there may well be one, but if you need to access these settings from a running machine there are MSRs you can poke.

You’re surely right about the incentives at play, and why no intelligence agency is going to spend millions doing x company’s validation work for them. But how in the world would selective patching work? How do you hide that?
Re:When Your Profiler Lies on Monday December 10, 2018 @12:55PM (#18649723)
Is the laptop using the HPET for the QPC timer? (10MHz..) and the added latency[0] of calling into that is messing up the reported timings in the profiler?

It may seem that way, but at least here in the UK homelessness is a huge problem in the immigrant community. It is virtually invisible though. You can get kicked out of the UK as a migrant (even from the EU) for being homeless, so keeping a low profile is essential.

I'm not even sure they're going to let you program the FPGA drectly (with HDL)?

I expect the main workflow will be using OpenCL to offload arbitrary work to the coprocessor along with a few Intel-provided modules capable of common tasks.

The great thing about having the FPGA on-die via UPI is that the cache-coherency, decreased latency and massive bandwidth will allow much more granular offloading of work. This is as compared with PCIe coprocessor where it only makes sense to offload larger chunks of work and minimise the communication and data passing between the two.

The greater the granularity of work that we can offload, the more viable the OpenCL/high-level synthesis/heterogeneous computing type stuff will be, as it will integrate more seamlessly into existing software development methods. This is the holy grail at the moment for FGPA vendors: to get to the point where software developers can program them on their own.

As to your point though I guess we'll find out soon what the dev tools for this will actually look like.

The flip side of that is, if they are stronger than us, many would take it for granted that they would attempt to communicate with us, even though we've made no such attempt to do the same with species on our own planet.

The high taxes for cigarettes (and similarly alcohol) should also be taken into account when considering net gains/losses. According to this [1] in the uk at least the taxes more than cover it for tobacco

Re:The Yale Problem Begins in High School on Wednesday November 25, 2015 @03:37PM (#10629514)
I agree that artificially imposing a "fair and balanced" framework onto news/discourse is a bogus concept as, like you say, the centre of gravity can be shifted in favour of nonsense ideas just by posing the question.

But in your second paragraph, you seem to imply (maybe I'm wrong here) that there is a sense of objectivity inherent in news reporting, because the reporting leads logically from the facts. However, the facts are hand-picked, meaning bias is unavoidably baked into the premise. In which case we are no closer to avoiding "focussing on opinion diversity", as the same opinion diversity arguments apply to choosing the facts on which to report.

Could someone tell me exactly what was wrong with the home icon in the top corner? I'm not defending the design - it looks like crap, but I couldn't put my finger on why that particular bit was wrong. There's a home icon top left in my browser as I type this.

What sort of range of engineers will this be aiming to recruit? Only the very best (and most expensive)? Or a range including more junior / less well-paid positions?
