Comment After weeks of delay.... (Score 4, Insightful) 32

bmajik launches a first post.

According to the mission profile, due to moderation, his positive karma will burn up during re-entry.

More seriously, I'm glad Space X is apparently doing things right. More successful launches... not just more launch attempts. The eyes are on them and lots of vested interests are looking to pounce and capitalize once they make a serious mistake.

Comment Re:What's wrong with Windows Server? (Score 1) 613

Nothing.

One critical difference: services.msc isn't actually responsible for orchestrating system startup on windows.

Services.msc is an administrative tool meant for interactive use. It is one of several administrative surfaces for interacting with windows service configuration. The commandline tool "sc" still exists and is still functional, and powershell undoubtedly has a more robust suite of tools for manipulating system startup.

The actual inner plumbing of starting up a windows machine is in some way abstracted from the management surfaces used. For instance, during the Windows XP era, a bunch of work was done on making bootup faster. Part of that work was done by allowing some parts of system startup to happen in parallel that were previously serial.

In versions of windows since XP, other subtle changes have been made to windows startup behavior to positively impact performance. The measure people most care about is how long until you can see your desktop, so some startup services have been moved into Deferred groups if they aren't implicated in giving you a login desktop.

All of these changes have been possible without critically altering the different management surfaces that exist for windows administrators. Service dependency chains, run levels, etc have been in the NT family since early days.

New features show up in these experiences over time; e.g. once upon a time every single service ran as the SYSTEM credential; now there are lots of pre-built discrete identities with different rights to effect some degree of privsep. But these were new values showing up on combo boxes in the existing tooling; not throwing away everything you knew and asking you to start over with something entirely foreign.

One key difference between Windows and rc/sysV is that the latter makes it much easier to promote a random shell script into something the unix startup orchestration knows about.

Windows services have a richer interface contract (start, stop, query status, etc) that is based on C-style calling conventions (iirc). Implementing something as a windows service as a practical matter requires knowing that's what you want it to be before you start coding.

The downside of the unix flexibility is that people ship broken ass shit like Ubuntu LTS where half your stuff is reasonable and half your stuff tells you, "hey, i'm an upstart job! So what you tried won't work any more for some reason that has no fucking bearing on your life! fuck you buddy!"

I got my start on linux in the a.out binary days, and simultaneously worked on Solaris and IRIX machines about 20 years ago. I've added other unicies since then. I'm very comfortable with both rc and sysV. Recent follow-ons like "upstart" have jut felt like hacky shit to me that unceremoniously throws out what met my needs and provides a fundamentally worse experience.

I spent a great deal of time debugging OSX startup a while back (http://blogs.msdn.com/b/mattev/archive/2004/06/21/161770.aspx) and that system was at least sensical and consistently implemented.

If you want the real deal on windows internals, the Windows Internals Books with Mark Russinovich are excellent, and explain the internal kernel concepts and data structures in tremendous detail. System startup is also covered, including the orchestration between smss.exe, lsass.exe, csrss.exe, and all other associated friends.

There was a very nice system, including PIN numbers to manage the POS terminals. Way back when stock trade was 49$, it was 25 cent per transaction irrespective of the size of transaction. This should have become zero. But that is not what happened.

The 25 cent transaction fee is charged by the acquiring bank, not Visa and Mastercard - whose fees for debit are typically 1 cent per transaction as they are a volume based business.

The reason that acquirers charge is because they incur costs associated with that transaction (including, but not limited to, interchange fees). If they didn't charge, it would fail as a viable business model.

Pre-paid cards still have to use Visa or MC to get the request for the money from the acquirer (who has the relationship with the merchant and typically provides the terminal) to the card issuer (the bank that supplied the pre-paid card).

Regarding AppStore vs MC+Visa, in order for Apple to be able to accept payments directly they would have to get an e-money licence so they could issue virtual debit or credit cards for use on their phones. By doing so, they'd still need the rails that Visa and MC provide - unless they really want to get into the business of connecting themselves to all the banks worldwide (aka becoming a payment processor).

Absolutely. There are all sorts of reasons why a person lands in jail. Some are in their control, some aren't.

But, to tie this back to the original poster and to the various responses, is it entirely beyond the pale to even entertain the notion that, possibly, due to some combination of nature and nurture, of social upbringing, evolutionary selection, and everything else, that maybe, just maybe, women and men are different?

And that, for some things, those differences may prove to be helpful or harmful? Isn't it better to have the discussion, to figure out what the differences are, and in some cases, make allowances or adjustments for them?

Premise: Women in western society, for a variety of factors both social and biological, tend to be more collaborative than adversarial. Assertion: Wikipedia editing is an adversarial process, in the same way the US legal system is adversarial: people argue their positions with the intent that the best argument wins. Implication of assertion: many women, who prefer collaboration to adversarial systems, will avoid Wikipedia.

To me, that is in no way sexist, demeaning, or anything else negative. But many people, whom I would term 'overly PC,' would attack me for even putting that little paragraph together.

Faith is defined as 'belief without evidence.' In other words, and *at best*, one makes a knowledge claim without any supporting fact or evidence whatsoever.

The problem is, 'belief without evidence' rapidly tends to turn into 'belief *despite* evidence.' In other words, the same knowledge claim is often made *despite* clear and contradictory evidence. That's a hell of a way to run a railroad.

Well, given that the majority of incarcerated males in the US are black, it could be argued, just as was previously argued, that you are implicitly saying that black people have inherently inferior reasoning ability.

Comment Re:You don't need to archive video. (Score 2) 455

You really seem to have an unrealistic expectation of how departments and the boards that oversee them will be allowed to use cameras. You also seem to have an unrealistic expectation that a prosecutor, judge, and jury will not press charges or convict someone simply because an officer did not have a camera present.

I think there needs to be a sea change in how the system works, yes. I doubt there will be.

The current LEO system is based on Victorian ideals about how some people are inherently noble and honest, and some aren't. This isn't true. Either a) hiring and training standards need to change, or b) technology needs to be used to smooth out the rough edges.

Comment Re:You don't need to archive video. (Score 3, Interesting) 455

I disagree, but we'll go with that. The camera now has an off switch. Any time the camera is not recording, the officer is off-duty, and does not have LEO authority and privileges. Note that this would be retroactive; you arrest a perp, it's all righteous, you get back to the station, and oh shit, your camera failed? Perp walks. On the spot. In court, the cop does not 'testify,' he comments on the video. No video? The cop doesn't get to talk. Period.

In the long run, humanity would be better served if people just learned to lighten up and not get so upset about things written by people they don't know and will never meet.

Death threats in the real world? Yes, that's a thing that is actionable. That's not what I'm talking about.

You do not have a right to never be offended.

It was a hard lesson for me when I was an opinionated teenager who hopped on IRC in the 90s.. all of these older smarter people were trolling me and being mean to me! Poor me!

It was also a GOOD lesson for me. In the internet of back then, the trolls were smarter, and there were no feelings police... no forum moderators... people said what they liked and you either dealt with it or you didn't.

And I look at people who come unglued over what they read on the internet and just shake my head.

An online forum with no rules and no judges and no consequences is one of the most interesting and wonderful things in human history.

I don't want it to die because of your hurt feelings. I'd rather you went somewhere else.
