ninjinxo··on S.Korea broadband firm sues Netflix after traffic surge from 'Squid Game'
Similarly, Australia had problems when Netflix was first becoming popular here, putting huge strains on the network and causing widespread congestion issues from 6 to 10 pm.

I wonder if we'll ever see a predictive home-caching system; if I watch the first three episodes of squid game in one night, it might be sensible to have my TV download the rest of the series overnight.

ninjinxo··on Beware of 'shrinkflation,' inflation's devious cousin
In Australia, supermarkets display the unit normalised price on the shelf tag (they do this to highlight the value of their own brand of items).

ninjinxo··on Steam required additional 57.51 GB download for a review
Tried this recently, and it's a complete mess if you run low on disk space. When trying to move a 100GB game to the SSD recently it turned out that:

1) steam will not rediscover the files automatically at startup or by attempt to launch the game, nor is there any specific option

2) the existing file discovery process is instantiated by forcing a new download of the game

3) this process will not begin unless there is enough free space for the game

So in the end, I had to copy the files back to the HDD to make space on the SSD, start an install of the game on the ssd, exit steam, copy the files to the SSD again, open steam and resume download, then wait for it to verify each file.

ninjinxo··on Temptation of the Apple: Dolphin on macOS M1
Whilst very impressive, it's a bit exaggerated, they should have been locked to the same framerate for comparison:

* 9900k is boosting to 5ghz which is sacrificing efficiency.

* 9900k PC is delivering a much higher framerate, so it'd also have much higher GPU utilisation.

* Afaik RTX3090 will have high power draw even at low utilisation (large card, lots of memory).

From anandtech:

>Should users be interested, in our testing at 4C/4T and 3.0 GHz, the Core i9-9900K only hit 23W power. Doubling the cores and adding another 50%+ to the frequency causes an almost 7x increase in power consumption.

ninjinxo··on Tim Cook’s Fortnite trial testimony was unexpectedly revealing
>you are free to use your own service

Do you have any sources on how restrictive valve are or have been with that, or is that just speculation? Can developers default to their own payment systems and bypass valve's, or is theirs required to take a secondary, less-accessible option (when it's even allowed)?

From the same thread, the mtx cut taken was a dealbreaker for redfall studios, so it certainly sounds like they didnt get the option for their own mtx transaction service: https://www.reddit.com/r/pathofexile/comments/1ogbo7/will_mo...

ninjinxo··on Bitcoin is a ‘boon for surveillance’, says former CIA director
Being generous you can mine ~$10 of crypto per day with a 3080 based on its hashrate, zero electricity cost.

So to transfer $1 million out over 3 years, you'd need to run mine ~$900 of crypto per day, ie. run 90 RTX3080s 24/7/365.

Also note that this would draw around 20kW.

ninjinxo··on France reports three new cases of thrombosis, more deaths after AstraZeneca jabs
I don't know how you can "deliver" such snark; if you gave 100 people shots and 30 developed clots, by your erroneous reasoning, N = 30.

What matters is the number of clots relative to the normal (incidence) rate, and the odds that you'd find 30 clots when sampling a randomized size-matched subset of the total population.

Please don't try to talk with authority on a topic when you're undereducated, aside from coming across as an ass, your brazen confidence and lack of knowledge just gives room to counter-argue that would instead harm your supported causes.

ninjinxo··on Scientists who never won a Nobel Prize
He effectively won in 1948. They don't do posthumous awards, so they abstained from giving out the prize that year, stating directly that: "there was no suitable living candidate".

And he didn't get one a decade prior because he was reportedly a tad racist, giving other candidates the edge.

ninjinxo··on The demise of the second-hand bookshop
I take issue with those sections too; you completely ignored that often customers won't know exactly what they want, importance of browsing, and the expert service provided that is the salesperson giving book suggestions and advice to customers.

Your points about alternative revenue streams by providing alternative services are directly covered in 20 year old tv show (black books) where a 'dysfunctional' bookstore either has them already implemented or trials them. For example, coffee is about keeping the customers in the store and browsing, people leave if they get hungry or thirsty. If you're actually deriving substantial profit from your hot drinks, then you're running a niche cafe, and you're in competition against legitimate baristas with fancier machines. It also takes up a large amount of space, and can cause volume issues otherwise.

Most secondhand bookstores are small, and items have a large volume-time footprint i.e. the turnover of any individual item is low. Get rid of all the low margin books for dining, and you ruin the browsing experience in multiple ways. You're just suggesting the secondhand bookstore should ditch it's secondhand books, and instead sell only high turnover popular stuff i.e. compete with modern normal bookstores, which are already doing beyond what you've suggested.

ninjinxo··on Simple Proof to the Container with Most Water Problem
I think it's much more clear if you start by trying to apply the constraint to the brute force algorithm.

The water container area is the distance the two sides are apart (width), by the height of the shorter side [therefore, the longer side acts to mimic it].

Doing brute force on array $[n_1 n_2 ... n_k]$;

You'd naturally start at $n_1$ and calculate volume $V(n_1, n_k)$ and work your way inwards calculating each volume. However, if at any point $n_1$ is the shorter side, then the secondary side $n_j$ now mimics $n_1$ in height; and therefore, any new side closer to $n_1$ cannot increase the height of the container (but would decrease the width, and therefore area).

Then you'd continue the same with $n_2$, breaking iteration when $n_2$ becomes the shorter side or if $n_2$ cannot develop a greater area than $n_1$ did (either n_1 > n_2 or oldArea > n_2 * width).

etc.

ninjinxo··on Why tennis balls are yellow or green
They're using low compression (lower speed, kid friendly) balls, often they're the same colour as your standard adult tennis balls just with a small alternatively coloured circle to indicate.

Look at the box of balls at 1:30.

ninjinxo··on Why tennis balls are yellow or green
Tennis balls are fluorescent; UV light gets reflected back as a set wavelength. This means they'll be brighter than a non-fluorescent yellow/green and thus easier to see. The amount of UV light (time of day, natural vs artificial light, overall light levels) will push the subjective colour between green and yellow.

This becomes a minor consideration when doing tennis court lighting upgrades, as Metal Halide lamps emit UV whilst new LED ones don't. Since tracking of the ball is primarily based on strong and consistent contrast against the background, having a UV light component that only lights the tennis ball is a major boon.

Tennis can be played under blacklight with relatively weak lights: https://www.youtube.com/watch?v=-x4mfQITXtM
