Comment Re:Subtraction... (Score 0) 119

Significant digits (figures)? Fuck that shit - everyone does it incorrectly, and it's fucking retarded when done "correctly". Seriously, why the FUCK would you consider a reading of "20" to be less valid than a reading of "21" when all else (measurement device, environment, methodology, etc.) is the same? Yet "2.0x10^1" is more significant than 20? It's absurd.

Further, 26.3 / 25.6 is a calculation, not a measurement, and you can't apply significant figures to raw calculations like that without fucking everything up. Significant figures are meant to handle the inaccuracy/imprecision of measurements. Only a few classes of calculations are imprecise (essentially because they are based on measurements or approximations, like trig functions on shitty, not cool angles).

What if I asked you to convert 1 meter to inches? 1 meter is exactly 5000/127 inches. Using 1 significant figure, to match 1 meter, we need to do 5000/100! 1 meter is not 50 fucking inches.

For 26.3/25.6 You get exactly 1.02734375.

Now, IF you know the significant figures of the measurements (and you don't necessarily just by seeing the number there), then you can do the following:

Assume 26.3 means a value in the range of [26.25, 26.35) and 25.6 means a value in the range of [25.55, 25.65).
We can take the extremes, 26.25/25.65 and 26.35/25.55 and get 1.0233918128654970760233918128655 to 1.0313111545988258317025440313112. The mean of which is 1.0273514837321614538629679220883, if you want to take a statistical stab at it. Remember our calculated value of 1.02734375? How does that compare?

If we used "significant figures" we'd get 1.03 for a 3% increase. But wait, it gets more retarded. Because if we calculate the percentage increase instead of the ratio, we get a different result even though they're giving us the same fucking information!
(26.3-25.6)/25.6 = 0.02734375, rounded to 3 significant figures gets us 2.73x10^-2, or 2.73% (as leading zeroes are never significant).

I knew you would come back with this shit. The window includes not just reading the post but the you landing on the story after it was posted, browsing at 0 or -1 to even see it, reading other posts attached to the story before getting to it, finally getting to it, reading it, deciding to reply, and ultimately typing out a response and hitting submit.

I simply don't believe that's gonna happen in less than 5 minutes or before 31 other Slashdot posts are created, especially since you're replying to a bad troll with a pointless post about how it's a good troll. No one takes the effort to praise shitty trolls unless they're the same shitty troll who loves the smell of their own shit.

I caught you, fucking deal with it.

It's considered poor form to reply to your own post just to agree with it or praise it.

Or are you going to claim that that AC posted, you loaded the page after that, read it all, reflected on it, had a chuckle, and decided to post about how you enjoyed that chuckle, all within a 30 post (sitewide) / 5 minute window? HIGHLY UNLIKELY!

A walkout is not in anybody's best interest and it's unfortunate that the union chose to do that

I'm generally anti-union because they almost always devolve into pieces of shit, but fuck AT&T and fuck the obvious bullshit line about a strike not being in anyone's best interest. It's in the best interest of the union (and hopefully of the employees).

Comment Re:SSD as cache (Score 1) 63

Are you kidding me? 2 GB of "slow" DDR3 blows away whatever SSD you're imagining in terms of both speed and latency. And the ASICs in RAID controllers can keep up just fine. They're typically designed to saturate all their internal links, with headroom.

When the battery backup fails, nothing happens unless the server also loses power.

Where are you getting servers with "100's of GB in DDR4 RAM" as a dedicated cache? Why would such amounts of cache matter when just a few GBs can provide a very low cache miss rate? How do you ultimately account for the lack of speed from running a single device compared to, for example, 4, devices in RAID 10? If you're advocating software RAID or various fake RAIDs, who is supporting it and what are you running on it? Can you boot from it?

Yes, I suppose the RAID controller itself could fail. I've seen it once in my life in a server that was already decommissioned and resurrected to give it away to someone else.

A modern file system with SSD write caches? WTF? I'm talking about the most popular "solution" in the server space - VMware ESXi. How do you set up software RAID in ESXi and use your "modern file system" as such? RAM-based SSD? You mean a fucking RAM drive? Those haven't been relevant for ages due to practical limitations on capacity and power, and of course the fucking cost. Maybe if someone goes back to them using HBM2 they'll be an option, but so far all I can conclude is that you're insane.

Comment Re:SSD as cache (Score 1) 63

RAID provides redundancy and speed. ESXi for example doesn't let you do RAID across multiple storage devices at a software level. My hardware RAID controller has 8 PCIe 3.0 lanes, cache, and battery backup. Yes, battery backup is still important. Yes, a RAM cache is faster than SSDs (though you'll wants to toggle the write cache policy). I don't live in pretend fairy land where SSDs never fail, and I don't shuffle shit off to a SAN/etc. device over network, fiberchannel, etc. because I want the performance.

trump is a disaster who advocated abandoning nato, japan, and south korea so that we could be "allies" with putin.

I'd rather be on good terms with the nation that's an actual superpower than:

1 - Continue to fund a failed organization nearly by ourselves
2 - Be military allies with a nation that's barred from having a real standing military, even if we've becomes friends since they were Nazi Germany's other half in WWII.
3 - Be involved with the powder keg that is South/North Korea.

But of course, it's not a this-or-that scenario.

We can and should demand that other NATO members pay their own way. We can and should step back a bit from other regions in the far east. We can (and should) be friendly with Russia. They're our actual ally. And yes, so is China. Yeah, both do shady shit most people don't agree with. That's their business, as is our shady shit most people don't agree with. But the media really wants to trump up this Trump/Putin link (despite zero evidence being proffered), while ignoring everything regarding China or everything Clinton has done.

None of this means we have to abandon NATO or our far east allies. And it doesn't mean we have to lick Putin's boot. It just means we stop paying for everything and we stop stirring shit outside of our borders.
