There was a lovely country club where I lived for a while. Out of curiosity I stopped by. It was only something like $5k/yr. I could have afforded it, but I didn't see any good reason to get a membership. They had a pool. I had a pool. They had a golf course. I don't play golf. They had tennis courts. I don't play tennis. They had their bar and sitting room. I have booze and a TV at home. They offered free wifi to members. I had Internet service at home. The buildings and grounds looked very nice. That only goes so far. "Ok, I'm sitting in a nice building."

I can't see wasting money just to say I have money to waste.

We are in a War on Faith, because Faith justifies anything and ISIS takes it to extremes. But in the end they are just a bigger version of Christian-dominated school boards that mess with the teaching of Evolution, or Mormon sponsors of anti-gay-marriage measures, or my Hebrew school teacher, an adult who slapped me as a 12-year-old for some unremembered offense against his faith.

Hm. The covenant of Noah is about two paragraphs before this part (King James Version) which is used for various justifications of slavery and discrimination against all sorts of people because they are said to bear the Curse of Ham. If folks wanted to use the Bible to justify anything ISIS says is justified by God's words in the Koran, they could easily do so.

18 And the sons of Noah, that went forth of the ark, were Shem, and Ham, and Japheth: and Ham is the father of Canaan.
19 These are the three sons of Noah: and of them was the whole earth overspread.
20 And Noah began to be an husbandman, and he planted a vineyard:
21 And he drank of the wine, and was drunken; and he was uncovered within his tent.
22 And Ham, the father of Canaan, saw the nakedness of his father, and told his two brethren without.
23 And Shem and Japheth took a garment, and laid it upon both their shoulders, and went backward, and covered the nakedness of their father; and their faces were backward, and they saw not their father's nakedness.
24 And Noah awoke from his wine, and knew what his younger son had done unto him.
25 And he said, Cursed be Canaan; a servant of servants shall he be unto his brethren.
26 And he said, Blessed be the Lord God of Shem; and Canaan shall be his servant.
27 God shall enlarge Japheth, and he shall dwell in the tents of Shem; and Canaan shall be his servant.

There would be easily missed negatives too. Are they suppose to wear one on both hands, or just their strong hand? When I was training, we had to practice both strong and weak hand firing, so we were just as proficient with either one. If they're only monitoring the strong hand, people will plan on using their weak hand to fire.

It's a good thing it didn't hit the US. If I've learned nothing else from Hollywood, I've learned this... If any object strikes another object moving faster than about 20 feet per second, there will be a huge explosion.

Except for the very very rare incidents which are strictly for comedic value.

Comment: Replacement batteries. (Score 4, Interesting) 131

by JWSmythe (#47734553) Attached to: Ask Slashdot: Where Can I Find Good Replacement Batteries?

Here's my experience. Buy something from eBay or Amazon.

Well, we've bought a lot of batteries from various people I've been harvesting laptop batteries for the 18650 cells to put into phone recharging backs so we can play Ingress for effectively limitless hours, and for eCigarettes. That's given me a look inside them, and what condition the actual cells are. Leftovers, I sell to friends and friends-of-friends at cost.

The recharge packs I have take 4 18650's, so if I get 2500mAhcells, I have a 10000mAh pack. I went with carriers that have a physical on/off switch, rather than the soft switch like the Anker has, so they can sit a long time without discharging. I haven't needed to change batteries on them yet.

Generally, I buy from eBay. I'm looking for the higher cell counts, and aiming for about $1 to $1.50 per cell. So a 8 cell pack I want to spend $8 to $12 on.

When I crack them open (always more work than it sounds) they all have the standard overheat sensors, which was the concern before about exploding batteries. They have all been wired well. Out of say a couple dozen packs, I received one that had a dented cell in it. It didn't hurt the performance of the cell, but since it was dented, I refused to use it or give it to anyone. Some of them, I've damaged the wrapper, so I re-shrink wrap if I'm in urgent need of them, or I dispose of them.

Regardless if it says on the listing that it's an OEM or 3rd party pack, almost all of them have had no-name cells in them. I did get a few true Sony, Panasonic, or Sanyo cell, but they are rarer.

They've all tested out to be the listed capacity, and they all have worked at the expected life expectancy.

The only big exception was the battery for my old cell phone. It originally came with a 1400mAh battery. The only cheap seller listed 1600mAh for about $10/ea. I used them, and they were fine, but they only lasted as long as my original battery when it was new. When they finally started failing, I pealed the stickers off, and the original markings showed they were 1400mAh batteries. If I had been paying extra for the extra capacity, I may have been upset. Since I just needed batteries that worked, it didn't matter much.

I played Ingress a *lot* with my phone though that period. That draws a lot of power, so I kept a couple spare batteries in my pocket all the time so I could swap them as needed.

My new phone came with a much larger battery (part of my selection criteria), and I don't play as much. I let it charge in the car when I'm driving. If I'm walking, still carry the external pack, just in case I need it.

So.. Pick something cheap on eBay. Look for listing saying they're "new". Don't expect a higher capacity batter to be any better than the original battery. Since you're looking for cheap, you can generally afford to get a spare. :)

It's good for your house too. I've seen houses where the homeowner never ran their A/C and they were proud that they saved money. They also had problems with mold, paint peeling, drywall falling apart, and various wood things in their house warping.

At one place I lived, there were ceiling fans throughout the house, which was nice. There were also some on our back porch. The ones inside stayed in almost original condition. The ones outside had rust on the metal parts, and the blades warped.

But this was a discussion about datacenters, so I talked about the corrosion problems with IT equipment.

Well, both sides get charged. We're all either charged on capacity or 95th percentile throughput.

I've never known a residential provider to charge for used throuhgput, because people have a hard time understanding it. People would flip out if their bill was $20 one month, and $300 the next. Rather, residential providers do a bit of math. They look at their bill, the aggregate bandwidth used, and the total Mb/s available to customers. Of course, they tag on a nice profit. There are additional considerations, like what do they need to provide extra services like IPTV, how much does it cost to maintain existing circuits, add new circuits, keep employees paid, travel costs for technicians, etc, etc, etc...

So, you get a nice low flat rate, because consumers don't use 100% of their bandwidth 100% of the time. Basically, they oversubscribe. If they do it right, you never know. If they do it wrong, you have shitty service and everyone complains.

At the datacenter we have equipment, we pay for the rack, power, and on the 95th percentile utilization of that circuit. So if we idle everything for a month, we barely pay anything. If we dump all the load to that datacenter,

If you're running a business where you need to be in a datacenter, your business model better cover all your costs. Otherwise, you'll be out of business quick.

No one gets a free ride. You pay for your end-user line. I pay for the line my server is one. Everyone's paid, and everything works.

since there is no air conditioning, you don't have a condensation problem

No, it's not HVAC induced condensation. Meteorologists call it the dew point.

Right at this moment, the temp is 53.3F with a relative humidity of 78%. The dew point is 47F.

You're suppose to run a datacenter between 40% to 60% relative humidity. Without a system in place to dry the air, they're asking for corrosion on parts.

You can't say computers are corrosion proof either. When I worked in a computer store, we had computers come in all the time that were in houses with no HVAC, so they were exposed to outdoor humidity.

I left some old gear in a friends garage for a while. One of the units was a used Catalyst 5000, with cards I didn't really care about. When I put it in the garage, it was in functional condition.

I decided to bring it back up to play with. There was corrosion on the line card handles, and I'm sure corrosion inside. Nothing looked bright and clean. There was visible corrosion on the cat5 pins (for the cat5 ports). When I took it out, it barely worked with lots of errors. Reseating the cards didn't help at all. I don't know (or care) which parts went bad, I sent it off for electronic scrap recycling.

Someone's going to be really pissed off when they spent a fortune on servers that have to be trashed because they stop working properly.

There are other parts machines in the garage too. I only go to them for fans, power supplies, etc. I had already pulled out all the memory and CPUs. Sometimes they still work. Sometimes they don't.

Specs have some wild numbers on them. Some say they operate in 10% to 90% humidity. Sure, they *can* run in it for a while. They aren't expected to survive in that kind of temperature indefinitely. I've seen some specs that say they'll operate over 120F. Sure, for a very short time. I had one place argue with me because the spec showed wild numbers, but they were already experiencing hardware failures for operating servers in an uncooled server room (the HVAC broke, and they didn't want to fix it).

You know, the difference between this company and the Titanic is that the Titanic had paying customers.
