Comment: The art of doing more with less (Score 4, Insightful) 167

..seems to be forgotten

Old time programmers remember squeezing every bit of performance out of a system

I remember doing image processing on a 4MHz 8088, in 1986, in assembly

Modern processors are INSANELY powerful..yet, most of the power is wasted on layers and layers of crap that incompetent programmers don't even realize is there

We need to re-discover efficiency in programming

Simple programs used by the general public could conceivably be served from the cloud to a browser

Even for those simple things, many people will still prefer local data and local control

I find it hard to imagine that serious stuff like CAD, video editing, digital audio workstations, etc could ever be forced into this model

I, for one, require local data, local software and local control..and I will NEVER rent software

..that they are totally honest and competent, and that weakening security will only hurt the bad guys

In the real world, government security is done by people who actually want to work for the government..if you're at the bottom of the technological barrel..hey, a job is a job..and government jobs have job security. Yeah, I have to take a drug test..but that's OK..I don't use illegal drugs (within the testing window)

If you are on the other side of the fence..all that matters is technical competence

You might be a criminal, or a terrorist, or someone who is just pissed off..but IF you have the ability to exploit the weaknesses that are intentionally introduced, under the pretext of national security..you will win

..of the personal computer era

Most of the speculations about how personal computers would be used were wrong..comically wrong

Most of the articles I see today about the Internet of Things seem silly, comically silly (NO, I don't want my refrigerator to order anything)

I suspect that there may actually be some useful ways to put "things" on the internet..we just haven't invented them yet

Comment: Going off the grid completeletly is stupid (Score 2, Insightful) 281

by MpVpRb (#49450245) Attached to: The Myth of Going Off the Power Grid

Why not use the grid as a reservoir..like a battery or capacitor?

When your local production exceeds your demand..push the rest into the reservoir

When you have a deficit..draw from it

Many people who advocate being off the grid are extreme isolationists..who value isolation over practicality

Sometimes, being a bit dependent, and interconnected, is good

They should dump the "content" divisions..the movie studio and record company

The "content" divisions crippled innovation by insisting that the first priority must be content restrictions

They should shift their focus from style to substance

The "style" advocates crippled innovation by insisting that the first priority must be fashion

They should do whatever it takes to return to being the world's best electronics company

Comment: Some new devices are unrepairable (Score 1) 840

Regardless of your skill, some devices are designed to be throwaway

Some are assembled with glue or welding
Some are completely encased in plastic by potting or overmolding
Some components, like ICs in BGA packaging, cannot easily be replaced with common tools
Many manufacturers don't offer repair parts..at any price
Sometimes, manufacturers grind off the identifying information on common parts to make repair and reverse engineering more difficult
Schematics and repair manuals are often completely unavailable, or very expensive
Many products require special tools that are unavailable at any price
Even if you have the skill to build your own tools, software interface documentation is rarely available, and often the interface is obfuscated
I have been building stuff, fixing stuff and reverse engineering stuff for many, many years
Yes, I agree that fixing stuff is a valuable skill that should be taught and not allowed to die
But, much of the fault lies with the manufacturers who aggressively resist any attempt by users to gain control over their devices

This practice should be illegal, we should have the legal right to fix stuff we own if we have the knowledge to do so

Vinnie Cilurzo of Russian River published a homebrew recipe for Pliny the Elder along with a detailed description of how he designed it

Mitch Steele of Stone wrote a book on IPA which included recipes for many of Stone's beers

Craft brewing and homebrewing have a long and interconnected history

Many craft brewers started as homebrewers and many craft breweries own homebrew supply stores and support homebrew clubs

The craft brewers I have visited freely answered any questions I asked

Yes, it's a cool demo..congratulations to a bunch of cool engineers

No, it's not a 3D printed car

At best, it's a crudely 3D printed body shell over traditionally made parts

There is no 3D printing tech available now that can print a ball bearing..or gears..or springs..or a motor
