If you are unsure about something, or it misses something you'd like added, feel free to e-mail the author. I am in touch with him at times and he seems friendly.
I remember he wanted to implement more than just detecting CPU instructions, but he did not want to make it bloated with checking for cache sizes and whatnot (can't remember the details).
Am I missing something, or is this article making a big fuss out of a relatively mundane privilege escalation? "MILLIONS AFFECTED, PATCH ASAP!" If you already have access to the machine, you can read physical memory and break KASLR.
This is excellent information, thank you for posting this! I was not familiar with this example previously, but it is a perfect example of summary statistics not capturing certain distributions well. It's very approachable, even if you had to limit the discussion to mean and variance alone. Bookmarked, and much appreciated.
I heavily caution against the feeling that "standard deviation is a simple way to essentially include percentiles." The usefulness of the standard deviation depends on the distributions that you are working with. Heavy tailed distributions appear a fair amount in practice, and the combo of summary statistics mentioned would not do well on those. Also, Madars' comment in this thread is a beautiful example of this: 4 completely different distributions, with identical mean and standard deviation (among other things). Histograms and percentiles, and if necessary their approximations, are more desirable for the above reasons.
I assume most of the distributions a marketing department would be dealing with are generally normal in which case stddev is a great way to analyze the data. This can be easily verified by just plotting said data and making sure the tails don't look weird.
I can't help but idly wonder what humans are doing when they are eyeballing the tails, to see if things look good. Like lets say we wanted to do the eyeball test but automatically. Would the best way be to use an image classifier on the plot? Is there something magic about the plot representation that would make it good even for computers to use?
Solid analysis, and a great read. I'm happy you posted this, as I was disappointed by the other Apple v Epic article that was making its way around HN today [0]. This article is significantly more substantive IMO.
The author makes some wise predictions on Apple's response to the lawsuit. Particularly on whether Apple will appeal the injunction because it was based on the UCL, but the injunction applies nationwide. Though no matter what happens, I hope consumers and developers get a fair shake.
When you tried the carbon steel pan, was it properly seasoned? They stick like hell before they are well seasoned, but seasoning them gives the carbon steel its non-stick properties. Woks are the ultimate tool for this, as they are carbon steel (so non-stick when seasoned) and their shape minimizes the amount of oil necessary to fry the rice. It is ubiquitous for fried rice across almost all of Asia.
Yeah but they use a lot of oil in those woks, and they get them really hot. Any Chinese street vendor with an open fire and cheap steel wok can do shit I can't dream of doing in my fancy ass American kitchen.
J Kenji Lopez-Alt has a lot of great wok content for American kitchens. In [0], he uses a butane torch to get the smoky wok flavor (wok hei) in a standard kitchen. He also reviews outdoor wok setups for those who want something close to Chinese street vendor-type vibe.
I cook with my carbon steel somewhat often, and it seems to have built up a nice thin black layer that keeps most things from sticking. Cleaning is a breeze, some dish soap and a couple scrubs. None of the black layer comes off.
Rice does not stick at first, but as it gets hot it does, unless I put around 3x the oil I would prefer. I have a gas range with a large burner so it gets very hot.
I don't have an account, and the change has been noticeable and annoying. It's more than just clicking on another tweet, though from what I can tell they've been A/B testing this behavior (sometimes I get it and sometimes I do not). On mobile, you can't click through to someone's profile from the tweet without creating an account. If the tweet chain is more than 4 or 5 tweets, you cannot read the rest without creating an account. It's prevented me from normal browsing habits multiple times, like reading the ASML twitter thread that was posted on HN a couple of days ago.
