Comment Apple has the same problem with launchd (Score 1) 308

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) 67

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.

Comment So does it still let you "always click to flash"? (Score 2) 96

So does it still let you "always click to flash"?

It'd be a real pain in the ass if, by watching one video, I have to always allow Facebook (major example) to run flash content, rather than just the specific flash content I authorize.

Also: where's the "click to run HTML5 video", please?

Comment Well, that's utter bullshit (Score 1) 579

Well, that's utter bullshit.

The very first link's very first sentence in the transcript:

"During the presidential campaign, Donald Trump suggested that he might favor creating a database for Muslims who enter the United States."

That's just adding religious affiliation to the already massive amount of information we collect about visitors entering the U.S., including their fingerprints and criminal records.

It's for visitors.

Slashdot editors: Please corrector your headline to add the word "Visitors" after the word "Muslim", and replace "Muslim-Americans" with "Muslim Visitors" in the first sentence of your summary.

Thanks.

No, what you're saying is that people with no expertise in a field feel that they have an ability to critique a rather specialized field they have no expertise in.

It's a fallacious appeal to authority, full stop.

You are claiming authority without evidence when you argue, but when they argue under the same circumstances, you claim fallacy.

You are engaging in a variant of the false equivalence fallacy called the false inequivallence fallacy.

You right, because you're right, and they're wrong, because they disagree with you, even though you are not an acknowledged expert, nor are you citing sources who are acknowledged experts. Full stop.

So what you're saying is that a lot of people who have no expertise in a given field believe that they're unrelated qualifications make them an expert.

No, what I'm saying is that their ability to think critically qualifies them generally to make judgements as to whether *your* qualifiecations in unrelated fields make *you* an expert.

And you have been found wanting.

Well, that all depends on what the rest of the world was doing. The US doesn't exist in a vacuum. If things get only a little bit worse in the US, but much worse in the global economy, then the president has done a good job.

That's not actually true, if the rest of the world's economy is an amplified following function of the U.S. economy. Which it is, since the U.S. dollar is the defacto world reserve currency. Yes, there are other reserve currencies, but as long as the vast majority of oil exchanges are denominated in U.S. dollars, it's the only commodity backed currency. That makes it the benchmark.

I can speak to any story on AGW, where every pseudo-skeptic poster shows up en masse to attack climatologists, so yes, the Libertarians and Conservatives here are a significant fraction of the posters.

I'm pretty sure half the problems are:

* so many of the people on slashdot are STEM educated, and realize correlation is not causation, which damages the narrative
* the people speaking in favor of GW tend not to be accredited climatologists with PhDs
* the people speaking in favor of GW portray it as having solely AGW origins, rather than humans as a contributing factor
* presuming (as I do) that GW is real, but not solely attributable to AGW, no one is willing to give a percentage breakdown on cause

It doesn't help that there is a strong following of conspiracy theories on slashdot, and the disclosure of the emails talking about investigators specifically squelching debate reeks of conspiracy.

It doesn't help that the GW == (AGW & GW) proponents tend to be rabidly antinuclear, and can't solve some of the basic technical problems -- most of which, BTW, could be resolved by placing the panels in orbit, rather than on rooftops.

It doesn't help that a lot of us think "So what? We'll just science the shit out of it".

You don't really have to be a libertarian or a conservative or a "pseudo-skeptic" (whatever the hell that is) to jump down the throat of an AGW proponent who's not an accredited climatologist. In fact, in this forum, it's kind of considered your civic duty, like serving on a jury, or going out to vote.
