It should be mentioned that the '100T device pictured actually requires the full paid version of ISE. The free-as-in-beer ISE Webpack only supports up to the '75T. Thankfully Xilinx implemented compatible packages through the devi

The hardware sounds dead simple, not to mention cheap. The service is the actual product here.

When I talked to somebody at Blue Waters (petascale supercomputer at UIUC), she told me that they had uncorrectable errors once or twice per day, even with ECC. Blue Waters has 22640 compute nodes that contain 16 cores each (we'll igno

Your comment dredged up old memories about this flight sim pod place. My friend (well, his dad) took us there a few times for his birthday. It amounted to ten minutes or less inside the pod, with primitive graphics and kind of twitchy contr

The comments on this EETimes article[0] are snarky but the criticisms sound cogent to me. 0: http://www.eetimes.com/document.asp?doc_id=1325499

I like VHDL, but SystemVerilog does have some very nice features.

Back maybe ten years ago, I was on an AT&T family plan, and the bill had every single text printed out on it. But texts were 10 cents apiece so I didn't really use them.

Yeah, enthusiasts were A/Bing MP3s a decade ago. There are new frontiers now.

Companies like Micron are looking to reduce their exposure to the commodity hardware business by getting more into services. This platform still looks pretty complicated to use, but Micron/Convey would probably be happy to take care of

I looked at Bowler's thesis. The DAC chips set the performance, the FPGA is just a natural way of interfacing to them. http://www.nist.gov/pml/div688/grp10/upload/Bowler15_thesis-...

Well, Reagan did tell them to "throw deep".

It made no difference for me. Try it yourself with a control. The "freeze a big block and cut off the ugly part" definitely works though.

I'm not familiar with the nitty-gritty of the LHC experiments, but in general the various detector subsystems have different response times and rate capabilities. There are certain types of detectors with explicit time granularity (e.g

The trumpet can be played one-handed, actually. Gets a little heavy after a while, but you can rest the bell on the dashboard. Also you won't be able to use the first and third valve slides to correct the lower notes, but who's li

Yeah, my hard copy is probably going to show up Wednesday or Thursday. Sometimes I wish the discussion on New Yorker articles would get delayed a week.

A fusion/fission rocket engine using a pinch seems pretty blue-sky at this point, to be honest. Their paper[0] only briefly mentions the main problem with cylindrical geometries: "With a successful Phase II award the team will tes

The JEDEC SmartBrief is a really great overview of what's going on in the chip industry. I also like getting Crowd Supply news every so often so I can see what's going on in the hobbyist space.

One of my profs told the class (NucE) that after the cold fusion announcement, people would come around the department to furtively ask for heavy water and such. So you can bet that smart people aren't going to pass up the opportunity

No, the X200s only came with TN screens. I actually swapped my 1400x900 TN screen for a 1280x800 AFFS. (In order to do this, you have to swap the entire screen assembly for a X200 one, _then_ swap out the standard panel for a HV121WX4-120.

That particular screen has horrible viewing angles though, move your head a little bit and the colors shift.

Vivado is good and bad. Vivado's schematic and device views are much better than the earlier FPGA Editor et al. The interface for adding Chipscope debug signals is quite nice. However there are lingering bugs. The hardware manager cras

Is Sonic fiber still limited to that stretch of Florence Ave? Wish they'd bring it to more residential areas (I'm in Santa Rosa), but I guess they're focusing on business customers.

You'll need to change the RAM primitive to the Altera equivalent, but it should fit just fine. Then you have to figure out how you're going to interface to it.

The problem is that what we send down cables aren't nice sharp square-edged waveforms. If you decompose a square-edge digital waveform into its Fourier series, you'll find that it takes roughly 10x the fundamental frequency of the

I've been buying my glasses from Zenni for a couple years now. I'm rather nearsighted (-7), with astigmatism, so I was pleasantly surprised that the optical quality is pretty good. The frames are somewhat less consistent though, I

I'm not sure what you mean by 'physically reroute traces'. If you mean, physically move a metal trace across the chip, that's not really possible at this point. One-time programmable devices (GAL and PAL devices that are

The theoreticians usually figure out what exactly to look at. The experimentalists figure out how to do it, and then carry it out. A common joke is that you don't let the theorists anywhere near the apparatus, because they'll brea
