Even when it's "Business ClassTM", you still don't get an SLA. That's why we don't use TWCBC anymore... they lie about the speeds, and they fix it whenever they fix it.
Static addressing is wasteful, subnets even more so. And every internet registry has frowned upon the practice for nearly 20 years. We'd've run out of IPv4 addresses LONG ago had they not stopped that shit. IPv6, on the other hand, is geared toward everything being a (rather unnecessarily large) LAN. But next to no ISPs in the US have any serious intentions for IPv6. (what little there is, is a colossal joke... a marketing hand-wave around World IPv6 Day.)
Port blocking was done out of f'ing necessity. There are just too many stupid people connecting machines to the internet. Running insecure software that they don't know how to secure -- and in many cases they don't even know was installed.
EXACTLY. Net Neutrality is all about packet level equality. No matter where they came from, where they're going, are what's in them, every packet gets the same equal and fair passage through the network. Under this plan, it would be "illegal" to prioritize your own (eg) VoIP traffic and/or degrade, or out right block, intentionally or otherwise, any competing service(s).
This has nothing to do with what you are allowed to do with your internet connection. The terms of which say it's for *your* *personal* use; by hosting "servers", you're allowing others to use that connection.
Yeah. I saw that too and was completely unsurprised by their "findings". They connected a computer to the diag connector. If you know the protocol, you can do ANYTHING to the car at that point.
Exactly. When you're handed a legal document, you send it to the lawyers. (where possible, carry it to them with your own hands.) Today, I (we, not in the ISP business) cut out the middle man... our registered business address is the lawyer's office. (sure, most expensive mbx on earth, but at least we aren't dealing with 'em.)
While I never had an actual warrant while working for an ISP, I have had a few "preserve the evidence" requests.
I wasn't talking about environmental impact. I was talking about water usage. Water pumped into a cooling tower is no longer available for use, as the point is to have it evaporate. (1000 gals go to the top of the tower, way less than that makes it to the bottom.) Thus, they USE water; it ceases to be available for any other use. In a drought, that's a real problem. Water drawn out of a lake for a heat exchanger, gets returned to the lake (or downstream of it); it's immediately available for other uses -- a bit hotter, but it's all still there. In a drought, that's a non-problem. (it's a problem for the power plant when the water level gets too low, or the intact water gets too hot.)
They're both "bad for the environment" in that sense. One is a source of heat pollution, and the other takes water away from other uses. Yes, where one has plentiful water, a tower has the least impact. (aside from the acreage required to build it.:-))
(Of course, we're ignoring the water used by office HVAC systems. And that is not pumped out of a lake.)
Most power plants built the lake in the first place. And they don't discharge into the lake; they discharge at or downstream of the dam -- so they aren't pulling in their own hot water. Next to none (read: NONE) of the intake water is used in the turbine steam loops -- those are 100% closed loops, if you're losing water you have a problem. (a serious problem for nuke plants.) [note: steam loops use distilled water -- ZERO minerals, RO reduces the mineral/particle volume, but it's not zero.]
That said, there are still numerous plants that use evaporative cooling towers. And they do, indeed, require a significant volume of water that is "consumed" -- it goes up as vapor. While it isn't "drinking water", it's water that's not available to the filter plant that feeds your taps. In a drought, you have a choice... cool the power plant, or have water to drink.
Many plants already use evaporative cooling towers. The problem is still there... water still has to be pumped into those systems where it is "consumed" (turned into vapor.) Ponds tend to be far too small. Lakes rarely have an inflow matching or exceeding the cooling need -- they're basically huge reservoirs buffering the inflow -- as such, a decrease in rain can (does/has/and will) cause issues.
While there's a great deal of saltwater on the planet, very few power plants are near the ocean. (esp. in the US) Plus there are all kinds of issues with using seawater. (*cough*corrosion*cough*)
No, because your (possibly illegal) house cleaner isn't a LEO. HOWEVER, they can present whoever opens the door the warrant and proceed to search the property. If nobody answers the door... they rarely go away and try again later. (they enter anyway)
Indeed. Except in this case the "logout" function simply instructs the browser to forget that cookie. Any machine that still has that cookie is still logged in. A logout should not only remove the cookie, but invalidate it's contents. Changing your password should invalidate every login immediately. Additionally, each "login" should create a different value.
If (when) someone gets ahold of that cookie, they will have access to the account until the thing expires (if ever.) You have no way to get them out of your account; a logout won't do it, changing your password won't do it. (not that they knew your password in the first place)
vxWorks, QNX... any number of much smaller, true real time OSes that are a far better fit for such tasks. Of course, they aren't free and the people who know how to program for them aren't cheap.
Consult a lawyer on the differences between "lost", "misplaced", and "abandoned". A parked car (or jet ski) is none of those. A contain falling off a ship at sea is "lost". (International law, maritime salvage, applied here.)
Bullshit. At the simplest, one need know only who to pay, how much, and how often. Information any accounting package can handle with ease. The problem is not finding a system -- tho they'll happily burn through millions over many years "looking at options"; the problem is getting from the old system to the new system, without making an even bigger mess.
There are private firms with more complex payroll systems than the US Military. Yet, they aren't running century old software on systems no one understands. It's not cost them billions totaled over the entire life of the company. EDS and ADP run payroll for *THOUSANDS* of companies, and they turn a huge profit on it.
The entire problem here is the people writing the checks are ".gov". Government contractors are there to cash checks first, if there's time left over, they may give you something useful. (It usually falls to sub or sub-sub contractors to get to where any real work is done.)
The sad thing is, anyone in the payroll office could walk to their local Office Max, and there on the shelf (for mac or windows) find software that can do much more than the 60 year old COBOL system they've been using. For a few $$$ even. The real work comes from getting all the records from the old system into the new system.
(been there, project abandoned instead of handling the conflicts in merging systems)
A motorcycle is a very small surface area to act over, with a significant amount of gyroscopic stability. Go ride by a semi holding a sheet of plywood next to you. The XL1 has a fair amount of siding be hit by wind.
Also, motorcycle tires have a rounded contour and tread up the sidewall, because they lean. A four wheel car cannot lean into a situation. A gust of air will push a car sideways; a cyclist can lean into it without a problem.
a) "racing slicks" (r-comp, race rubber, etc. or in other words "NOT STREET LEGAL") are not designed for use on wet pavement. b) if they are "hydroplaning" on drive payment, they're broken. (dried out, too many heat cycles, or it's just too cold to use them -- they don't work worth a damn until heated up)
What I'm talking about is a tire's cornering capability. That is mostly a function of width. (along with many other factors) Just watch highspeed video of cars turning hard at speed. (I've seen some where the tire should've come off the rim.)
Even modern US road legal cars can have problems with cross wind. Granted the safety regulations test these things, so they aren't out of control when a semi screams by. The XL1 simply doesn't have the tire traction to hold it's own here; without computers (abs) the loss of control will not end well.
The problem with RWD is that 99% of drivers have never driven one and have no clue how to properly handle one. But then, 99% of drivers simply don't know how to drive at all, so it doesn't really matter.
The thin little tires are what bothers me most. There's a damn good reason we don't use "bicycle wheels" on cars... traction and cornering stability. (and the reviewer breifly mentioned how quickly the tires give up.)
Have you ever been to a lemons race? This is a long standing standard Saturday night. If you cannot replace a transmission in the rain and mud, by flashlight, then Lemons isn't a place for you. (and most of the time the team's half drunk while doing it.) Formula Un it isn't, but knowing nothing about the car you're racing is not going to turn out well for you.
They aren't "gun detectors", they're metal detectors. Guns, being made of metal, set them off. But so will my glasses, wrist watch, zippers, even the rivets on my Levi's(TM). As far as I've seen, the bullets are still made of metal, and thus detectable by the current generation of security machines.
Note: the article doesn't say they had any bullets for that gun on them. As such, they were walking around with slightly more plastic on them, and there's nothing illegal or even questionable about that.
It doesn't have to be particularly poor, just not sufficient for a data center. You want the heat load in the room to be as near 100% equipment as possible -- no leaks from outside the room. You also what the cold to stay in the room -- i.e. not blowing through cracks (or holes) in the floor, wall seams, through doors, etc. It's fairly simple to test the efficiency of the room... turn off all load, and watch how much the HVAC has to work to keep it at the setpoint.
As I said, I don't know the specifics of your situation. It could simply be the small increase inside created significantly higher temp in the outside loop -- thus significantly improving your heat rejection. Of course, it could also be the result of the DC matching the surrounding office temp, thus the HVAC isn't working to cool the rest of the building. You knowingly changed one out of a multitude of variables and concluded it "good" without a thought to the other variables. Honestly, you got the result you were looking for, so "why" becomes less important.
This suggests your DC may be rather poorly insulated.
I don't know your environment (pre- or post-) so I cannot say what that +7F did to the thermodynamics of your HVAC system... +7F room, +20F servers, +50F exhaust? (greater deltaTemp == faster / more efficient energy transfer) for example, if you're in Az and your heat rejection (cooling coils) are only reaching 120F, they aren't going to be very good at dumping heat into >100F air. (this is where water cooling should be used.)
(Note: I had that "talk" with the nuts that built our last office DC... placed a system on the roof rated to 95F... next to RDU. 6months out of the year it was nearly useless. The system we've inherited at the current office is much better... it uses the building chilled water during the day.)
