Comment Re: Init alternatives (Score 1) 220

Let's rephrase that: Linux finally has an init system that does something devleopers find useful enough to make their software use that functionality.

How dare systemd be useful? It should stay as useless as all the rest, so that we can have more useless init systems and switch back and forth between those.

Comment Re:Billing address? (Score 1) 72

Maybe getting the card numbers (card, code, expiry) is just phase I of weakness with limited applicability for in-person transactions. Nobody asks my address at the electronics shop when I have a $800 TV in my cart.

And perhaps they have other databases that allow them to correlate incomplete card numbers with names and addresses to create useful online transactions where they info can be asked.

IMHO, the only useful solution to this is two factor RSA-style authentication. Go ahead and know all the card info, but unless you can guess the random digits it would be worthless. Pity that fraud doesn't cost VISA and merchants can build most of their costs into product pricing.

Comment Re:No safe-guards? (Score 1) 72

Why not just build 2 factor authentication into the card itself? They could offer a card with an in-built RSA token or a way to use a smartphone app for cards without token hardware.

Something tells me this is something we should have, but given the sparring and profiteering over getting chip enabled terminals in the US (I'm STILL swiping at many terminals). I suspect that it's not the two factor part that keeps it from happening but the terminals and merchant software costs combined with a bunch of middlemen who figure that fraud deterrence for merchants and consumers isn't their problem since they make merchants eat it, who then make consumers eat it in higher prices.

And then there's the spreadsheet guys, who predict transaction fee revenue drops from failed transactions and doom-and-gloom of lost sales pitched to merchants.

Comment Re:3D editing is hard (Score 1) 171

I think 3D modeling software is a big reason 3D printing hasn't been the home revolution.

I've been using computer based 2D drawing software since MacDraw in the 1980s and have used it for drafting home improvement projects, woodworking projects and floor plans. I've downloaded Sketch-Up a few times and always found myself baffled quite quickly, even tinkering with generic rectilinear shapes.

And even drawing some boxes or other regular geometric shapes doesn't get you very fair in a world of tapered curves, irregular shapes, etc, let alone the same needing accurate scale and tolerances down to the millimeter.

And it's not that it's impossible, either, but it's got a wicked learning curve over 2D just doing the drawings let alone the phase where you have to consider how you design will actually be output by the thing making it.

Strangely it's almost the blade-and-razor model in reverse. In theory, they should give you the razor handle (the easy to learn 3D design software) for free so that you'll buy the 3D printer and supplies, but I suspect that in terms of cost, the easy to use 3D modeling software is the actual expensive part and the 3D printer should be the cheap part. It's kind of like 2D design software -- an annual contract for Adobe Creative Cloud is almost more expensive than a decent color laser printer.

I'm not sure if that's a serious question or an attempt to troll, but regardless...

Speed is not why you should want (or not) systemd. It's Linux. How often do you expect to reboot the thing, anyway?

In the spirit of "Do one thing and do it well", systemd's goal is "manage services and dependencies". To that end, the only real interaction you normally have with systemd is to start or stop a service, and view the associated logs if some service is misbehaving. In my opinion, them, I don't really see the point in changing one's distro (including support lifecycles, development trust, and organization philosophy) just to swap out init. It's just not that big a deal.

It most certainly is if you manage servers!

Most performance evaluations include an uptime requirement. Most businesses it is 99.97% uptime while some Slashdot readers it might be as high as 99.99% or 99.9999% if they work at Amazon or a Wall Street trading firm where any downtime costs millions a minute.

If servers randomly do things behind your back or you restart one during a standard change and it doesn't come back up and your change window is between 1am - 3am (like my employer) you can be in hot water if you can't get it back up if something weird happens during a patch or other activity. SystemD's benefit is it's downfall which is that is event driven. Let's say theoretically you can have SystemD launch tasks or do something in the event your network is hacked or if one of the NIC teaming cards fail. That sounds cool. Problem is if it fails and does something that crashes it.

I am learning FreeBSD now more after I stopped touching it in awhile. Sometimes boring but predictable non event oriented boot only procedures are bah but predictable and nice. You know what you are going to get. It's in that ugly RC script hack but hey you can debug it!

Comment Re:Because it's not software (Score 2) 107

I thought Henry Ford was a visionary because of his business model -- an assembly line that could mass produce cars for everyone -- not because he necessarily innovated the automobile concept itself.

Musk's advancement mostly seems in the electric drivetrain, less so in the business model. He wants to do direct sales, but while it runs against the grain of the existing car sales business, existing regulation and low production volume make it appear less than revolutionary, especially when many products are sold directly buy their maker.

Less hours and more free time drastically reduces the value of your labor. Since MBA cost accountants figure overhead as fixed + variable costs it makes sense to fire you and overwork the other guy.

During the recession everyone worked 70 to 80 hours a week or 0. You just have one guy do the work of the laid off one or get rid of the secretaries and assistants or lead scouts and place the burden on the other guy ... And still expect same numbers.

Time is never reduced ever

Comment Re:You should *NOT* be projecting.... (Score 1) 61

I think there are fair arguments about not distracting other drivers. But one thing nice about this vs. a HUD is that it actually projects imagery onto the surface you're supposedly to be looking at -- you want to focus on the road in front of you generally so seeing directional markings there is completely natural and doesn't require a change in visual focus or the distraction of having to look through a HUD's imagery to the road beyond.

Some potential ideas to make is less distracting for others -- don't display markings when another car is within a distance where they may easily see them, display markings such that they're oriented/displayed in a way meaningful to other drivers or communicate that they should be ignored. I drive through intersections many times a day with turn arrows and lane markings not relevant to me and I don't get confused.

I also wonder if there's some way of projecting them with a light color, pattern or polarization that's made more visible by filters laminated into the originating car's windshield, especially if it managed to do it such that other cars windshields acted as passive filters due to their polarization.

I think it's a great way to put information exactly where it belongs for driver visual focus. Distraction to other motorists *could* be a problem, but overall people are already visually attuned to ignore markings that are backwards or don't apply to them and their direction of travel. Roads have all kinds of markings already and nobody complains about excess street markings. And it may be possible to project them in a way that makes it difficult for other drivers to see them at all.

A wall won't stop them, but it will slow them down enough for people behind the wall to shoot them dead.

Don't be naive, if refugee/migration pressures are this severe do not think of a second that the people with will demand the invading hordes without be stopped by any means necessary.

I'm of the opinion that it's happening already. We argue around the margins about immigration, pretending it's about jobs, racism or some other bullshit but I think at the heart of it people really are nervous about long-term resource access. It's low level and you can easily rationalize away any kind of urgency about it, but I think the level of news coverage about refugees into Europe, the noticeable increase in Hispanic populations in the US over the last 10-20 years, etc is invoking something of a panic mindset.

We laugh about Trump's wall now for all the obvious reasons but it wouldn't surprise me at all if fortifying the border specifically against mass refugee influxes doesn't become something more than a fringe idea.

Comment Re:Disturbing, but practical (Score 1) 404

If you see mosquito larvae infesting a pond, do you kill the larvae or do you wait until they grow into mosquitoes and bite you before swatting them?

Speak for yourself.

Myself, I store all mosquito larvae for at least two years, then I torture the resulting mosquitos and cross-breed them with more aggressive specimens, before finally releasing them two years later back into my own backyard.

That method may not be particularly effective, but at least it makes me feel good.

Comment Re:DEA already has rescheduled and overruled itsel (Score 1) 146

I'm on board with most of that, but if economics was a good enough explanation we wouldn't have seen the DEA making opiates much harder to obtain -- more intensive prescription databases to get doctor shoppers, more intensive audits of prescribing physicians, and the rescheduling of hydrocodone from III to II. The irony, of course, is that it has jacked up street prices and moved many low-level pill users accustomed to uniform dosing to street heroin, which despite DEA enforcement has become cheaper than made-in-the-USA pills, and with all the worse addiction and overdose outcome you'd expect.

I'm more inclined to think that the DEA was largely a political creation designed to attack the counterculture of its founding era, using criminalization of LSD and marijuana as an excuse for law enforcement action. This I think goes a long way towards explaining the DEAs aggressive moves against any substance with recreational value.
