A big problem with increasing the clock speed is that your processor still needs to wait for the DRAM to respond. Modern processors are crazy smart about prefetching, caching, and running instructions in parallel, but at some point Memory bandwidth and latency begin to dominate over CPU clock speed. Many players have started looking at puting multiple dies on the same substrate with high-speed interconnects to reduce memory latency and improve throughput. Those improvements could help push the usefulness of higher clocks a bit further.
Can you not make a coherent quadrature detector? I was under the impression that those were pretty common in optical communication systems. Edit: nevermind, 230GHz, so millimeter wave but mixers and oscillators exist at that frequency, are the noise figures just too high to use?
I mean, yeah it makes them less profound. Individual identity is not entirely defined by place of employment. I'd imagine the vast majority of people see their employer as the means to pay bills rather than a political entity whose goals they explicitly support.
Wow. Your post is so misleading it borders on outright lying. Those $31k contributions come entirely from individuals. Comcast the company did not donate any money to her. Conflating individual contributions with Corporate contributions is massively misleading. Comcast has 164k employees. Do you honestly expect that most employees of Corporations agree with the political goals and objectives of their parent companies?
The government cannot compel speech. I don't think that using the power of the government to require some types of speech against the wishes of private entities solves the problem you think it's solving...
The difference is that none of those examples dominate their market. The problem isn't "Amazon uses their platform to promote their own products" it's "Amazon uses their market dominance to promote their own products which might not otherwise be competitive"
That's true for IIR filters but not FIR filters, which modern (This century) signal processing uses. A 1024-point windowed sinc will have linear phase across the entire passband, that's one of the main reasons we use FIR filters.
The thing is that small changes in the mean affect the long tail of the distribution in a very visible way. How is it biased to point out extreme weather events like this which are happening more frequently now than in the past? The NYT has a great graphic illustrating this point. https://www.nytimes.com/interactive/2017/07/28/climate/more-...
I've had a similar experience making an FM transmitter. I used a small air coil inductor that wasn't well secured to the PCB as part of the resonating circuit. My FM tuner would pick up ambient noise since the small sound vibrations would ever so slightly change the size of the inductor, modulating the frequency. Ceramic capacitors also have this problem. The small metal 'fingers' are susceptible to vibrations which change the plate distances, and thus the capacitance. Use your imagination to think about cases when this might be of interest for certain groups!
Yeah that's the problem. 2x is too big and 1x is too small on 3200x1800. Luckily there's a workaround to scale text to 1.5x which for most purposes is fine.
I have the older 13" 3200x1800 screen and it is amazing. I put Ubuntu 18.04 on it since it wasn't available as a developer edition. The display scaling is my only problem but that's more a gnome thing. Running it with Windows was a almost perfect (why, Xilinx can you not do display scaling...). I thought I wouldn't notice the extra resolution due to the small screen but it both looks really nice for text and allows me to scale everything slightly smaller so that I can fit more on my screen for productivity. That being said, I use it as a laptop, on my lap. The extra resolution is pretty useless if I'm using it on a desk or table. But for that I have an XPS15 + 27" 4K setup.
I've noticed the best "online" teachers excel in predicting what questions students will have and addressing them preemptively. I think the person behind 3Brown1Blue on YouTube does a fantastic job doing this. Throughout their explanations, they interject with things such as "Now, you might ask why I did it this way... well here is that reasoning" and then "but you also may have observed this and here's why you did".
In some ways, I feel like the ability to anticipate student's questions and hangups and respond to them is a far better predictor of their efficacy as an instructor than how well they understand the material or the quality of the lecturing.
I mean, you can make a RADAR with a single transistor, 2 diodes, an exotic but off the shelf VCO, and clever transmission lines. I doubt the R&D cost is very high for for the MMIC here.
[1] does not say that it works, don't misrepresent the study. It found that certain markers were increased/changed by the supplement and that a few of the observed physiological functions appear to have improved a merit further study. Also, N=24 so ymmv. Seems like something that may be useful after further study but your conclusion is misleading.
Or groups of people live in certain geographic areas and are not served by public transit or near government offices like a DMV. That can have the effect of making it generally harder one one group despite equal competence.
Adding to that, the word "bitch" is more contextually associated with certain power structures in office environments. Pretending that words are just words is completely naïve and it usually signals that someone is upset that they can't be a jerk to other people without consequences.
Your libertarian fantasy would be fine if it wasn't for the fact that you 2 tonne steel box can kill /other/ people when you drive excessively fast and crash.
Small nitpick. The range resolution improves with increasing pulse/chirp/waveform bandwidth, not increasing carrier frequency. It's true that at higher carrier frequencies there is more bandwidth available and thus better range resolution is possible but the relationship is slightly different than "delta_r ~ frequency"
What the hell are you talking about. That has never been my experience nor the experience of people I know that have been there within the past 2 years. Don't fearmonger about crime.
I'm similarly skeptical that replacing 70 watt bulbs with 15 watt bulbs with poor power factors would end up being a wash. IR loses from the increase in reactive current would not cover the 55 watt gap.
A radio amature most likely can't construct a bandpass filter with a high enough Q to filter out all of the spurs while still getting a usable signal. Releasing a tool like this and handwaving away interfearence concerns with an abstract refrence to 'proper filtering' is still iresponsible.
That's a neat party trick and all but abusing spurious emissions/harmonics to broadcast in licensed spectrum without proper filtering is just plain irresponsible. At low power, with an unmatched antenna those signals /probably/ won't make it out of your house but it's not good practice to spew harmonics all over the spectrum, especially GSM bands. I also can't believe that they are working on increasing the TX power. Purposefully emitting all over the spectrum is both iresponsible and illegal.
Side note: Balint Seeber, the lead on this paper, has given a number of excellent talks on wireless communications and signal processing. I'd recommend his series of "Hacking the wireless world" talks (available on youtube) given at DefCon for anyone interested in digital signal processing and RF security.
