Comment Re:What is the carbon footprint? (Score 1) 73

The "hydrogen economy" would produce huge amounts of CO2 if we use the cheapest most efficient means of producing hydrogen, namely hydrocarbon fractionation. I had read of energy balances for ethanol that show it requires more energy to produce than it actually produces. Not to mention the stupidity of using food for fuel. Ethanol drove up the price of corn enough that there were food riots in latin America.

Having seen this blow up in our faces before I want to raise a warning flag early so we can nip a bad idea in the bud.

Comment Apple has the same problem with launchd (Score 1) 241

Apple has the same problem with launchd.

In Apple's case, the trigger messages are not entirely asynchronous, as with systemd, but they may as well be, since the Mac ports being used most frequently do not have peer information available, and are (effectively) just integers.

This leads to what I call the "on behalf of" problem.

Something starts running. And you want to know *why*. Clearly, it;s running because someone requested one or more of the services it provides -- but there's no way to know who it is running "on behalf of" to provide that service.

Say, however, you figure out that service 'C' is running "on behalf of" service 'M'.

Who is service 'M' running "on behalf of"?

In Mac OS X, it's *almost* possible to get the information as to where every thread in everything is pending a response from something else in its stack. But it's not possible to figure out the entity relationship, because you can't trace the other end of a connection.

So I can perhaps figure out that an application is pinwheeling -- that's the cursor that the display server puts up on a Mac OS X application when it's not responding to "are you alive?" chatter from the display server within it's main app loop. It happens when someone does a blocking operation in the main app loop, instead of packaging up the operation that might block, and giving it to a thread delegate instead: it means someone made a coding error, because they expected an operation to never block ...and then it blocked.

So I actually want to see where it's blocked (which I can) and see who it's trying to get work from, that's not responding to the work request -- which I can't, because I can't see "the service on the other end".

Both launchd/Mach ports, and systemd suffer from this problem.

But if I were permitted to ask the question... then I could find the next entity in the chain... and I could ask "what are you waiting on?", and follow the chain down to the actual problem.

Automatically.

The display server puts up the pinwheel, I option-click it (or whatever), and a dialog pops up and says:

MagicDraw is hung waiting for RemoteFilerPro,
which is hung waiting for access to "remote_filter_cache_file.ca",
which is hung in the kernel on a permissions check,
which is hung, waiting on DirectoryServices,
which is hung, waiting on mDNSResponder,
which is hung waiting on a network response from "VPN.bob.net",
which is hung waiting on a response from network interface "Wi-Fi2" ...which would be frigging useful. Because then I could say to myself "Oh. The VPN is down because the Wi-Fi is out. Better reset the router again."

But I can't do that.

Comment Social media companies urge UK government to ... (Score 1) 51

Social media companies urge UK government to issue national ID cards to everyone over the age of 4.

Social media companies also urge the UK government to implement a back end system so that, given the card, they can verify underage status or not in a government database.

Social media companies further urge that the UK government have plans in place, should the ID card be stolen, for issuing a replacement ID with a different number, and repudiation of the stolen ID, such that it's no longer considered valid ID, by maintaining a revocation status bit in the back end verification database.

Social media companies finally state that the plan can not be implemented without these systems being put in place prior to deployments, and if they are unwilling to get the necessary infrastructure built so that it's even possible to comply, the UK government can go stuff themselves.

Submission + - How to View the SpaceX Falcon 9 Return to Flight at Vandenberg Air Force Base (perens.com)

Bruce Perens writes: Silicon Valley folks should, sometime, take the opportunity to view a launch at Vandenberg Air Force Base. Lompoc is 4-5 hours from the Bay, 2.5 hours from LA if there's ever no traffic. An upcoming SpaceX launch is notable because it's their return to flight, months after their last attempt blew up on the pad during a pre-launch test. Read how to view the launch.

I imagine it would have terrible battery life with that spec

Laptops like those are mobile workstations, meant to be moved from one desk to another. They are usually plugged in at all times. At least mine was when I had one. I personally would love a laptop with a desktop class processor even if it only have a half hour battery life. But I've never found one yet.

Eich resigned because of external pressure on the Mozilla organization. I hear that one of the lobbying activities against him was when the dating site "OK Cupid" started informing Firefox users who accessed the site of Eich's activities and that they should download a browser made by people who don't nominate someone with gender discrimination issues to be their CEO. At the time, 8% of OK Cupid customers were there to arrange same-gender meetings.

They felt he was the public face of the company.

Russ Nelson published a piece on what he theorized was the economic motivation of Blacks to be lazy, and was booted off of the Open Source Initiative board. He wasn't thinking about how it would be perceived. A modified version of the piece is still online, but not the version that got him in trouble. In general, executives are seen as the public faces of their organizations even in the case of Nelson, who was not the chairman of the board, but was simply a member of the executive board. In Nelson's case, it wasn't that he made publicity appearances and press releases, it was that he was one of the people with the power to direct the company (and thus a more real face of the company than soneone who just does PR), and folks did not trust that someone who wrote what he did would behave as they would like in that position.

Playboy departed the nude photo market due to the vast and unending supply of photos and video of all manner of naked people doing sexual things which one can access via the Internet.

However, one can make a case that a good deal of the past content of Playboy was about objectifying women and to some extent the publication still is about that.

It was a dumb decision. Several people just weren't thinking. They're embarrassed now. They learned, and won't do it again.

It was only 1967 when the United States Supreme Court decided Loving v. Virginia, a miscegenation case. Preventing blacks and whites from marrying, as the State of Virginia (and many others) did with laws on its books until it was forced to remove them in 1967, is an issue of racism, nothing else. One doesn't have to be thin skinned to be disgusted by racism.

Why should I feel any different about gender discrminiation? Texas had a law on the book making homosexual relations illegal in 1998, and two men were arrested for it and similarly to Loving, helped to strike it down in the courts. Marriage discrimination is yet another legal wall erected by the prejudiced. Doesn't take a thin skin at all to oppose it and its supporters.
