Imagine doubling the processing power of your devices!

This might be hype, but it seems like great news if true -- we're getting several years worth of Moore's law type improvement's (a doubling every two to three years) for "free". Who said there is no such thing as a free lunch?

Maybe the growth of AI will exceed expectations!

No this is not some great revolution doubling the speed of all computers. It might be technique to help speed up some very specific architectures for some specific tasks. It is not a change in paradigm of anything. Did you read the article by chance?

Does that mean that Google could "colorize" all of the pictures in all of history twice as fast as it did the other day? The mind boggles.

8:51 -- The claims could be somewhat true, in that very few codes run at peak performance given the hardware that is available, under the constraints of running at minimum cost and minimum wall clock time (or minimum power consumption in mobile devices, etc). It can be far more than a factor of two in lost performance.

Of course, many scientific codes involve computations such as modeling events in several dimensions or in the quantum domain, and suffer from unfavorable scaling in any case, so the algorithm in use may play a greater role in changing the scaling power law or exponent, it may not be that important to lower the prefactor.

Better operating systems, languages, and compilers and scheduling algorithms can help performance though, and this could be part of the answer.

In real code environments, code maintenance and refactoring can also be an issue, code can be bloated or intentionally obfuscated by developers, and of course in high performance computing there can be perverse incentives to utilize more resources rather than less, and so on. Code features also become bloated and obfuscated, as in Microsoft office and Windows, as a way of generating a technological moat, driving ever-greater computing needs for basic tasks.

Maybe AI coding tools will cut this Gordian knot and lead to more efficient and maintainable code, it could also erode some of the power of entrenched platforms and operating systems at the big tech companies, leading to a new wave of innovative and performant software.

Plutonium Shots on NIF.

Tri-Valley Cares needs to be on this if they aren't already. We need to make sure that NNSA and LLNL does not make good on promises to pursue such stupid ideas as doing Plutonium experiments on NIF. The stupidity arises from the fact that a huge population is placed at risk in the short and long term. Why do this kind of experiment in a heavily populated area? Only a moron would push that kind of imbecile area. Do it somewhere else in the god forsaken hills of Los Alamos. Why should the communities in the Bay Area be subjected to such increased risk just because the lab's NIF has failed twice and is trying the Hail Mary pass of doing an SNM experiment just to justify their existence? Those Laser EoS techniques and the people analyzing the raw data are all just BAD anyways. You know what comes next after they do the experiment. They'll figure out that they need larger samples. More risk for the local population. Stop this imbecilic pursuit. They wan...

Trump is to gut the labs.

The budget has a 20% decrease to DOE office of science, 20% cut to NIH. NASA also gets a cut. This will  have a huge negative effect on the lab. Crazy, juts crazy. He also wants to cut NEA and PBS, this may not seem like  a big deal but they get very little money and do great things.

Why Workplace Jargon Is A Big Problem

From the Huffington Post Why Workplace Jargon Is A Big Problem http://www.huffingtonpost.com/2014/04/25/work-words_n_5159868.html?utm_hp_ref=business&ir=Business When we replace a specific task with a vague expression, we grant the task more magnitude than it deserves. If we don't describe an activity plainly, it seems less like an easily achievable goal and more like a cloudy state of existence that fills unknowable amounts of time. A fog of fast and empty language has seeped into the workplace. I say it's time we air it out, making room for simple, concrete words, and, therefore, more deliberate actions. By striking the following 26 words from your speech, I think you'll find that you're not quite as overwhelmed as you thought you were.
