Comment Limitations (Score 2, Informative) 474

Instruction level parallelism in superscaler core designs have hit a limit. More pipeline stages becomes counter productive when a misprediction requires a flush. Thread level parallelism exploited by multi core designs can only go so far; only certain tasks can exploit massive parallelism(e.g. ray tracing).
Increases in clock speed have hit a wall with current silicon based semiconductors. Exotic semiconductors and incredible cooling systems aren't practical for the mass market.

I used to write code for an enterprise network switch platform and our C code base started being built with g++. The toolbox analogy is apt. Forget the object orientated fluff, just use C with the STL container library. You have an optimized, standard interface library into commonly used data structures.

SF Bay Area tax revenue has been increasing just fine: http://www.sfchronicle.com/business/networth/article/Bay-Area-property-tax-assessments-on-a-roll-8349188.php

Don't forget that under prop 13 the property tax of a unit is reassessed at market value when it exchanges hands or a brand new unit is sold. With the current housing boom(bubble) going incredibly strong in this part of the country tax revenue has been increasing significantly.

There's no excuse for SF's budget problems except for its own politicians. In SF there are homeless everywhere. Just like there was 20 years ago. Yet in 2016 the SF budget states $241 million was spent on the city's homeless problem. Nearly a quarter of a billion dollars! Currently, the city employs over 30,000 workers to serve a population of 830,000. In 1970 there wasn't even half that many city employees and the population was at 714,000. With what technology and automation have done in 45 years, why is there such a ridiculous ratio of city workers to city population? Especially glaring to the people who live there who still see trash in the streets and have to keep an eye out so they don't step on human feces walking down the sidewalk.

My question for you is - Why should the rest of California's home owners pay with the repeal of prop 13 because San Francisco(and its residents who keep voting for this type of government) is having budget problems running its own socialism experiment?

Bay Area property tax revenue has been going up quite well.


Don't forget that under prop 13 the property tax on a unit is reassessed based on the sale price when it exchanges hands or a newly built unit is sold. With the current housing boom/bubble going on that means quite a large increase in tax revenue.

There's really no excuse for the city of SF to have budget problems except for the greed of its own politicians. In San Francisco there are homeless everywhere. Just like 20 years ago. You have to be careful not to step on human feces in certain places. Yet the city's budget states that $241 million dollars was spent on its homeless problem in 2016. Nearly a quarter of a billion dollars! San Francisco employees 30,000 city workers in a city with 837,000 people. In 1970 the number of city workers was 15,000 serving a population of 714,000. The current ratio is outrageous, especially to people living in the city who wonder what's the result of having all these employees when the streets are filled with trash. The argument as to why SF city worker compensation is so high is that today's city employees are trained in specializations. That's a fair argument. Yet why does the city need twice as many employees for a population that's only 15% greater than it was over 45 years ago? When modern technology has brought more automation in that time and not less? Half of SF's budget goes to its employees.

My question for you is - why should the rest of California's home owners have to pay with the repeal of prop 13 because San Francisco decided(through its residents who keep voting for this type of government) to run its own socialism experiment?

It's not as if Windows 10 offers any significant, or even real, architectural advantage, and it's not like Linux doesn't have plenty of its own development tools. So far as I can tell, Windows 10 has absolutely no developer advantages at all, and in fact, simply represents a pointless extra layer for any developer working on Linux.</p></quote>

Nothing significant? How about good GUI development tools. I write code for a Linux application written in C++. The best setup I've found is Visual Studio w/ WinGDB attached to gdb running the process in a Linux VM. XCode can remotely attach to gdb as well.

What's the best Linux solution for debugging? Emacs?

<p>My only problem with "The Martian" is that the premise for him being marooned on Mars (at least in the film) is completely bogus. Mars has 1% of the atmospheric pressure of earth, there's absolutely no way that a dust storm could cause anything like the effects it had in the movie. It certainly could not lift rocks, never mind knocking over a rocket.</p></quote>

I thought this was an odd statement:

"While the P100D Ludicrous is obviously an expensive vehicle, we want to emphasize that every sale helps pay for the smaller and much more affordable Tesla Model 3 that is in development. Without customers willing to buy the expensive Model S and X, we would be unable to fund the smaller, more affordable Model 3 development."


Given Tesla's history of missed dates and missed production numbers, should we be concerned about the Model 3 viability and timeliness given this statement?

You can compare pointer addresses in C. The signature uses void pointers so that any pointer type can be passed. In the function they are cast as a byte type so the arithmetic works(the third argument is the length in bytes). e.g.

void memmove(void * d, void * s, int len)
   char * src = (char*) s;
   char * dst = (char*) d;

   if (src < dst)
      for(int i = 0; i < len; ++i)
         dst[i] = src[i];
   else if (src > dst)
         dst[len] = src[len];

Comment Re:Telecommuting FTW (Score 1) 163

I've been telecommuting for the past two years, for a virtual company, and I hope I never need to give it up.

There are some things I miss, in particular (a) my wife not needing to keep our kids somewhat quiet during school vacations, and (b) having a ready-made social life due to being cooped up with coworkers.

But after working out some of the kinks, and with a just a little extra self-discipline, it's so, so worth it.

Even if an employer needs to pay and $5k/year to cover telecommute-specific costs (such as decent video conference equipment, etc.), it seems it must be a win-win for just about everyone involved. (At least for software development jobs. Not sure about other kinds.)

$5k/year for telecommute costs? Maintaining a VPN and having decent conferencing equipment shouldn't cost that much. And if it does, the savings in office space(have you seen what SV office space costs?) more than makes up for it.

Not really. At this point Russia has the ability to deliver a crippling first strike on the entire west and they will do everything possible to maintain this position. You can think of the US as a toxic parasite nailed to a table. It can of course still spew forth toxines, when injured but there are so many antidotes to its products in place, it can be slowly killed without fear of retaliation. We can choke it off economically by trading without dollars, we are in absolute control of it militarily.

The US, as well as other countries, have second strike capability with its nuclear subs.
