Oh, the columns are offset by 6 months aren't they

(btw I didn't click the link before because I assumed it had the answer, rather than the problem :P)

trichoplax

Ah I see. Well, it does, but the answer is the problem...

@Sp3000 Even if you compare with the next row down, there still seems to be a problem...

VTCAKAVSMoACE

lol

I just used 3 languages in that birth years question.

Sp3000

@trichoplax Is there? If you compare (5500 vs 5800) and (6000 vs 5800) for a single year, the +300-200 = 100 seems consistent with the fact that the gap between 500+1000 and 1600 is 100

Unless you mean something else

1:18 PM

Hmm okay I think I get said other problem

trichoplax

The problem I see is that a 500 salary increase only pays you an additional 500 per year, which is only 250 per 6 months

Because the figures shown are for 6 months, it isn't obvious that the 500s should actually be 250s. It's only looking at the annual figures that it falls apart

The left column increases by 2000 per year

quartata

Like spelling 'dammit' correctly -- with two m's -- it's a troll that works best on the most literate.

TimmyD

@trichoplax No, the pay raise is 500 every 6 months

quartata

I may or may not have started doing this

trichoplax

@TimmyD I read that as "Every 6 months, your salary increases by 500"

But the salary is still an annual figure

TimmyD

@trichoplax Ah, so meaning a chart more like this one --

I think the problem with this question is that it's a bit like asking "If you put $1 in your bank account at 1% per annum, how much would you have after a year" to which the answer is "Compounded how often?"

Bald Bantha

trichoplax

@Sp3000 Even if you compound arbitrarily often, there's still an upper limit on how much you get per year, so I think there's a bigger problem - the table ends up doubling the salary increases

Is the accept tick exempt from the cap too?

VTCAKAVSMoACE

Sp3000

@trichoplax The problem seems to be that fact that with the 500 per 6 months rise, if you're comparing to a year ago that's two increases ago, so there's a gap of 1000 per 6 months, or 2000 per year total

It... seems to me there's wording issues at play here though

@TùxCräftîñg

trichoplax

@Sp3000 I can't see a way that a year would give a 2000 increase. Every 12 months there are two increases, each of 500, so that's 1000 per year. If the salary starts at 10000, then it will be 11000 12 months later. The cumulative total of pay received will be affected by the frequency of pay increases, but the salary itself is simply 11000, because they are fixed size increases, not percentage increases

zyabin101

Hey, it's been four days since launch of my new Quitter feed!

I should probably share something. :3

TimmyD

2:12 PM

Yeah, it has to do with the wording. If they're intending "During this six-month period, we're basing your actual paychecks on a total yearly salary of X" and then changing X by 500 every six months or 1600 every year, then you get the situation that taking the 1600/yr is better --

TimmyD

If, however, they're intending "Your starting pay is 5000 every six months. Under plan A, we increase that by 500 every six months. Under plan B, we increase that by 1600 every 12 months." then you get the chart they have in the book.

zyabin101

"A question from a new user gone horribly good." :P

trichoplax

@TimmyD I think that's the source of the error. I can't imagine any circumstance where "salary" would mean "pay per 6 month period"

TimmyD

Well, that's the weaseling -- they state you're getting a pay rise, without mentioning the period.

zyabin101

2:16 PM

Well, ping me when you finish discussing salary increases.

I have readied a headline.

FryAmTheEggman

Also, for whatever it's worth, those befunge programs prints the reversed list of digits after the first 9 as a base 9 number.

trichoplax

@TimmyD Yes, I wouldn't complain if they specified a 6 month period, but in the absence of specification I'm pretty sure they intended the period to be a year. In any case, if "salary" means per 6 month period, then there should be 1600 added in the right hand column, not 800. Otherwise the definition of salary is different per column

Question to the hard ware guys: For windows, would you prefer installing a (graphic card) driver manually or is the built in windows Treiber "good enough"?

@El'endiaStarman Do you know about the principal component analysis / SVD ? It makes a whole lot of sense if you think about it that way. Especially when you e.g. use the SVD with zeroing for pseudoinverses or dimensionality reduction in ML.

TùxCräftîñg

the builtin ~~triber~~ driver is crap

Nathan Merrill

@flawr why not experiment?

Rainbolt

@flawr I prefer installing graphics drivers manually. I've encountered crashes with auto update multiple times. A majority of the improvements (meaning more FPS while playing games) are found in the first year after the release of the card, so I will frequently update for a while, and then stop updating.

TimmyD

@flawr I would always install the driver direct from the manufacturer

Rainbolt

I assumed all drivers came from the manufacturer. I thought his question was "auto update or manual update" but now I'm not sure.

TimmyD

2:49 PM

Because of standards, Windows has a lot of "good enough" drivers.

VTCAKAVSMoACE

New sandbox post should be popping up any moment

Rainbolt

Well in that case the answer is easy. The driver from the manufacturer is better. I can show you charts from LinusTechTips that shows improvements in FPS with the exact same card using newer drivers every couple of months.

TimmyD

Additionally, there are drivers that are "released" by the manufacturer as ones that passed extremely stringent HQL testing and can therefore be bundled in e.g., Windows Update mechanisms.

flawr

As far as I know the windows drivers are made by the manufacturers, but might be just minimal or out of date.
