Comment Re:memory management circa 2014 (Score 1) 637

Sorry. coding 8-bit, 32-bit and 64-bit embedded, as well as desktop apps. You missed the point. parent said

go out and buy another gig or two of ram for a few bucks. seriously...its hard enough to find professionals to build software without getting bogged down with mallocs and leaks for god's sake. when java first hit in the 90's, prettty much the #1 feature was its automated garbage collection...why now are we debating this now?

The reason I'm arguing it's important is that there are still a lot of applications out there where dropping in another gigabyte of RAM isn't an option. Embedded doesn't always have gigabytes of memory; sometimes your cost constraints put you in a 25 cent processor with kilobytes of memory. I'm coding 8-bit processors because I write code for embedded application which are cost sensitive. I'll use a 32-bit processor if the design specs show it's called for.

Comment Re:The Story of Mel (Score 2) 637

I just went on a rant at work because one of our programmers decided, at some point in the past, to write blocks of code in inline hexadecimal. With little to no comments. It had a bug... five bugs actually. I spent two days in the code, finding and fixing problems which should have taken at most a couple of hours, all because someone decided to be a "Real Programmer", aka elite ass. I don't care what the esteemed Mr. Raymond and Mr. Nather (the author of the article in catb.org) believe; we created higher level languages, like C, to make it easier to write and maintain code. I can write code directly using machine instructions too; but, I have too much work to do. As the parent said, don't be like Mel, we all have real work that we have to get done and someone will hate you later.

Of course they're saying a vaccine is coming. You don't think they're trying to keep a general panic from occurring? Step 1, tell everyone it can't happen here. Check. Step 2, tell everyone it can only be passed via contaminated body fluids. Check. Step 3, tell everyone that a vaccine is imminent. Check. Step 4, ... you don't want me to tell you about step 4.

Comment Your bulding is wired with 3 phase source. (Score 1) 260

Based on your commend, I suspect someone wired out your building in 230V 3 phase, since it's "close enough" to get away with in place of 120V/240V split phase; and, lets them put in more efficient 3 phase pumps and air conditioning systems. Some residential buildings and residential neighborhoods are wired out in 3 phase but the private residences only uses 2 of the 3 phases, except for the A/C system. Usually that's done in 208V 3 phase; but, it's conceivable someone could have put in 230V transformers.

Comment Re:FUD filled.... (Score 1) 212

It sounds like this transformer had its center tap grounded and was the path to ground on one side of a ground loop as the geomagnetic field moved under pressure from a CME, inducing a common-mode current in the long-distance power line. A gas pipeline in an area of poor ground conductivity in Russia was also destroyed, it is said, resulting in 500 deaths.

One can protect against this phenomenon by use of common-mode breakers and perhaps even overheat breakers. The system will not stay up but nor will it be destroyed. This is a high-current rather than high-voltage phenomenon and thus the various methods used to dissipate lightning currents might not be effective.

Submission + - Letter to Congress: Ending U.S. Dependency on Russia for Access to Space 1

Bruce Perens writes: I've sent a letter to my district's senators and member of congress this evening, regarding how we should achieve a swifter end to U.S. dependency on the Russians for access to space. Please read my letter, below. If you like it, please join me and send something similar to your own representatives. Find them here and here. — Bruce

Dear Congressperson Lee,

The U.S. is dependent on the Russians for present and future access to space. Only Soyuz can bring astronauts to and from the Space Station. The space vehicles being built by United Launch Alliance are designed around a Russian engine. NASA's own design for a crewed rocket is in its infancy and will not be useful for a decade, if it ever flies.

Mr. Putin has become much too bold because of other nations dependence. The recent loss of Malaysia Air MH17 and all aboard is one consequence.

Ending our dependency on Russia for access to space, sooner than we previously planned, has become critical. SpaceX has announced the crewed version of their Dragon spaceship. They have had multiple successful flights and returns to Earth of the un-crewed Dragon and their Falcon 9 rocket, which are without unfortunate foreign dependencies. SpaceX is pursuing development using private funds. The U.S. should now support and accelerate that development.

SpaceX has, after only a decade of development, demonstrated many advances over existing and planned paths to space. Recently they have twice successfully brought the first stage of their Falcon 9 rocket back to the ocean surface at a speed that would allow safe landing on ground. They have demonstrated many times the safe takeoff, flight to significant altitude, ground landing and re-flight of two similar test rockets. In October they plan the touchdown of their rocket's first stage on a barge at sea, and its recovery and re-use after a full flight to space. Should their plan for a reusable first-stage, second, and crew vehicle be achieved, it could result in a reduction in the cost of access to space to perhaps 1/100 of the current "astronomical" price. This would open a new frontier to economical access in a way not witnessed by our nation since the transcontinental railroad. The U.S. should now support this effort and reap its tremendous economic rewards.

This plan is not without risk, and like all space research there will be failures, delays, and eventually lost life. However, the many successes of SpaceX argue for our increased support now, and the potential of tremendous benefit to our nation and the world.

Please write back to me.

Many Thanks

Bruce Perens
