If my processor is marketed as 1200 MIPS but can run at 2000 MIPS for up to 0.5 seconds out of every 15 second window (due to thermal constraints), but only up to 1700 MIPS when executing SIMD instructions for 0.5 seconds and 1000 MIPS ther

Most professional photographers who used DSLRs ten years ago are still using them. Electronic viewfinders are fundamentally inferior in terms of the viewing experience and battery life, but have other pluses like light weight, low cost and

Should we also stop using tax money to subsidize education for doctors? College athletics are education too. It's not like you become a tennis pro by just hitting the gym a lot. The best players study the rules, study physiology, study

Here are two options which various people might find intuitive: 1. Make a good old numeric for loop like "for ii in range(len(df))" with df.iloc or df.ix, etc. 2. Use df.apply() to create a new DataFrame with your changes. Both of

I haven't even seen that Top Gear episode but I'm sure it's the same one. This, the main highway in Naypyitaw, is very famous for its incredible width and underutilization. Trip Advisor rates it the #2 best place to visit i

Of course they are colored. Like this: http://www.evertopcomms.com/144-fiber-count-gyts-fiber-optic... It is still a lot of work, and so far not automated.

This is not how Intel sees it. They describe hyperthreading as a single core having two (or more, but usually two) sets of architectural state which basically means registers. It's not two cores, it is one core that can switch between

Hoarders love regular CL too. I sold a huge and somewhat expensive 21" CRT monitor on CL and the buyer asked me to deliver it. When I got to his door, he cracked it open and said just leave the monitor in the hall. The apartment was co

I've seen a similar group without the second rule. It's a mess because the instant anyone posts anything there are many users who reflexively post "Q" (as in queue for item). Then when you reply to give them the item, th

It's not only about minimizing total infections. If it were, priority would be given based on social sphere sizes, eg priests and postmen before old people. It's also about giving people a vaccine they can believe in, which allows

zipfile uses zlib which is C. But it's even better than that: it releases the GIL, so it gives linear speedup with multiple threads. If you need to (de)compress a bunch of files, you can do them all at once quite easily using e.g. conc

Sure but can you sell a thermal camera that takes e.g. one second per exposure? And costs even more than current models? I'm not sure there's much of a market there.
140.
by jzwinck 6y ago
Thermal cameras measure much larger waves (7-14 microns as described in the article), and their sensitivity to amplitude is high. A major limiting factor in camera sensor resolution is signal to noise ratio. It is well known that if you bum

Little endian has one nice feature for network communication: integer fields can be expanded or shrunk without changing code of the peer so long as the actual numbers don't overflow. Most mainstream protocols don't really take adv

I think the majority of binary integer data sent and received today is big endian. Calling it "legacy" seems like a stretch. People are still designing plenty of brand new protocols using big endian. When I encounter a little endi

Write tax laws that are clear, simple, automatable and enforced. Then people will pay tax. Complicated tax laws beget complicated tax dodges. At this point no one in the UK or US or many other countries is able to answer a simple question l

How about recvmmsg? I never saw that before Linux, and haven't been able to find a reference to anything similar on say AIX or Solaris.
