Super rough summary of the first half: in order to pick out random vectors with a given shape (where the "shape" is determined by the covariance matrix), MASS::mvrnorm() computes some eigenvectors, and eigenvectors are…
The idea is that memory-only data systems like HyPer are able to make design decisions that make them significantly faster that disk-based systems (eg postgres), even when the working set fits entirely within cache for…
Wonder if this has anything to do with the sliding window: > Sonic only keeps the N most recently pushed results for a given word, in a sliding window way (the sliding window width can be configured) Default window…
> Joules-Thomson effect is what allows for refrigeration I don't think this is true. The "simple" model of refrigeration taught in highschool is just a carnot cycle running backwards, and this can be modeled with an…
Heads up this weights all your scores towards 0. If you want to avoid this, an equally simple approach is to use (x+3)/(y+5) to weight towards 3/5, or any (x+a)/(y+b) to weight towards a/b. It turns out that this…
Free fillable forms is hard to use for taxes in general, but this page is specifically for people who want the CTC without having filed taxes (presumably you otherwise would have gotten the CTC when you filed takes).…
I doubt it? At least the number times the "last updated" column appears on SQL server stats [1] leads me to believe it collects stats async with updates to the table. The only system I've heard of that relies on…
I think I generally agree with the majority of the comments here that burn in can serve a useful purpose (especially if you can't find a high probability density point to start from), but I also wonder: if burn-in vs no…
If you're new to differential privacy and looking for an introduction, I highly recommend the Dwork and Roth book, especially the first three chapters: https://www.cis.upenn.edu/~aaroth/Papers/privacybook.pdf Frank…
I'd also like an answer to this one. It seems like most of these explanations would also apply to plastic or metal getting wet, so why does cloth get so much darker than other materials? It feels like the fact that…
This is basically the issue. If a single line from the bottom of left is present at the top of right, it will fast-forward all the way through left and fail to match anything else from right. The hard part with diffing…
re: efficiency, I think this blog post does a decent job explaining: https://auth0.com/blog/beating-json-performance-with-protobu.... Basically, it doesn't make a huge difference if you're communicating with a…
I might be missing some context here, but usually the L_infinity norm means the max norm, or the maximum absolute difference over all components (data points). This gives (min + max)/2 as GP suggested. Wikipedia entry:…
To be honest, I'm a little confused by your answer. Aren't high contention and deadlocking workloads essentially the same thing to a deadlock-detection db? I can imagine some patterns where that wouldn't necessarily be…
Does anyone know why they use deadlock detection rather than deadlock avoidance (the simplest avoidance algorithm being simply to always acquire locks in the same order)? I can't find a good reference right now, but I…
Even assuming you meant "upper bound" instead of "lower bound", this isn't strictly true in theory. To achieve high throughput with large latency between nodes, all you have to do is group transactions into large…
I'm a little confused about the columnar database comment: > Performing queries across billions of metrics looking for labels that only match a few of them (a common scenario with time series data at scale) is really…
Worth noting that (I'm 99% sure) you're absolutely allowed to benchmark Oracle, just not publish the results publicly. It's pretty common for DB papers to compare against postgres and a number of "mystery" databases…
Could you link/explain how you get those hardware prices, specifically the servers and desktops? Are the available for the average consumer (ie not making a bulk purchase)? I have very little experience buying hardware,…
I think the idea of spending to upgrade your helper AI sounds really interesting and potentially novel, but it's important to push back a little bit on the idea of "removing all the rote" from an RTS. day[9] (ex…
Do you think you could point me towards a source for "mixing reads & writes with a SSD lowers performance"? This seems reasonable, but I've never actually heard it before, and a cursory googling didn't turn much up. I…
Slightly related question from a non-expert in ad-blocking: is it possible to block interstitial ads? While the freedom to render a page as you wish seems to come with controlling the browser on your computer, I can't…
Agreed. Especially given that these rate limits seemed to be aimed at stopping something catastrophic like spammers using 100x allotted capacity, a 2x innacuracy shouldn't really matter. The solution was interesting,…
But depending on node failures, couldn't the same client successfully run cas(nil, A) -> cas(A, B) -> cas(nil, C), with all operations succeeding? Say the first two operations only succeed in writing to a single node…
