For Parkinson's the odor comes from chemicals expressed by sebaceous glands.

I didn't know this until reading your comment. It does seem weird that the skin is so permeable, so I looked it up. At least in this case, it doesn't seem to have anything to do with permeable skin.

EDIT: It's mentioned in passing in the linked article: "For one experiment in Manchester, sebum samples were taken from the upper backs of test participants." Other sources are more clear about the relationship to sebaceous glands.
I agree that it's dumb. The only clear alternative, N years after the work was created, has its own problems though, such as trying to figure out when each work was created to determine whether it's in the public domain or not.
I worked in Biotech for a while and spent years working with various cell lines i.e cancer. Cancer has a distinct smell. I was out shopping one day and the scent hit me, I turned around and next to me was an elderly man in a wheelchair. I am definitely a super smeller. After developing chronic migraines I'm now very sensitive to scent, every product I use has to be unscented and I have to avoid crowded areas due to the risk of setting a migraine off. It's the super power I wish I didn't have.
Tbh I'm tired of the Nature articles about this. When is something going to change?
GitHub 2fa is the worse implementation than the most I have encountered. They tell you that you can save recovery codes in facebook but guess what? It doesn't work! So you get lulled into having recovery codes safe in your FB account until you need it when they simply through error message that "oops, sorry. something went wrong, contact customer service.". So next, you try to find customer service and guess what? They have the worse setup for that as well! They have enterprise, pro and all kind of variations. You are expected to literally learn about their internal hierarchy of customer support organization and you scratch your head who the hell runs this thing? When you finally actually get through all that you find out pro is not pro and enterprise is not really enterprise and, BTW, whole team if off on some training this entire week so don't expect any response. You see, they don't think you actually have a job or any kind of urgengy. So you wait for response for days and likely you won't get any. There is no phone nuber to talk to human and emails are bounced around in their internal hierarchy. Losing your phone could be pretty bad thing if you have setup github 2fa.

Given how we all have placed GitHub front and center of our lives, there is no excuse for any of this. Even if I'd no recovery codes, I would expect GitHub had some process to get back access back. GitHub account should be looked upon with same reverence as bank account. The idea that you need to forget about money you have in bank account because you lose your phone and recovery code is mind numbing. They could charge you $500, run professional background check on you, get your credit card/bank info and verify it's really you, wait for 30 days, remove private repos and then grant you access again at least for your public repos. That's what I would expect an efficient customer obsessed organization to do.
That's great! But it's not enough to contribute positive things; you also need to not contribute negative things. It is like society: good deeds don't mean you can break laws.

Another factor too: people tend to overestimate the value of their positive contributions and underestimate the damage of their negative ones. Probably by an order of magnitude in both directions, in which case many of us are adding a hundred times less value than we imagine, if we're adding value at all.
Why do people of such intelligence subject themselves to being interviewed by dumb-as-a-rock Joe Rogan?

I must admit that I often watch his interviews because he invites interesting people, but I can't help but cringe when Rogan gives his opinions.
You go guy! Trees are worth more than most people.
I kinda want to go spear hunting but it is illegal where I live. The only animal I can legally spear is a fish in my State an I would rather fish with a flyrod than spear.
Is it the cancer or the treatment that you're smelling?
I worked in an animal lab on masters research that required strict 12/12 light cycles. 12 hours bright white, 12 hours red light (circadian rhythms impacted the study design). No windows and no support from post doc or supervisors (both had different serious health problems). I'm quite an upbeat person so it was fine short term, it did put me off academia and purusing a PhD though. Good decision in retrospect and after staying in contact with my peers who have not learned much new and have in my opinion over-specialised.

> what does this have to do with OP

OP made the point that Google does not want to address this problem and may even facilitate it (maybe passively). However, they have actively prevented progress on search engines that may be more difficult to SEO engineer/hack (because of their specificity) and particularly have prevented people with good vertical search algorithms from building a business (read: actively sabotaged their business). [1]

In any case, Google known as well to quash any other small projects that they feel challenges them. [2] [3] [4]

Simplifying Azure DevOps Pipelines with Decorators
I'm actually a bit confused by why it matters at this point. HDMI is ubiquitous, can handle a high enough resolution/ rate that most human eyes can't distinguish better, and is relatively cheap. It's an optimized, widely available format, and does a great job. USB is a downgrade for this particular task. Other than novelty, I don't see a reason to ever do this.
I give a 25% referral fee standard and bake it in on the backend. Value based projects have plenty of "margin" where I am happy to share the profit. That business wouldn't have happened otherwise.

Board games have been solved. Now the big boys are working on Starcraft and Dota 2, and it takes a shitload of money to pay for the compute and simulation necessary to train them. No something you can do on the cheap.
How many of them are doing real research, though? Corporate researchers improve ads impressions and academics researches are busy generating pointless papers or they won't be paid. Very few if any do actual research.
I’m assuming this project used the Times API as a starting point, which provides article metadata (such as url and keywords and headline). I’m not particularly interested in word frequency as I am story count and placement. For example, an A1 story about Trump is the same as an A1 story about Obama, regardless of how many times the words Trump and Obama literally appear in the story. Part of this is that it is quantization that maps with how stories are actually written an edited — words used in the story’s headline and lede grafs are the highest quality signals. The other thing is the very nature of the label “Trump”. Many stories about Trump are specifically about his commercial and real estate holdings, which are all branded “Trump”. To quantify a story as being several times as “obsessed” with Trump, just because the story involves Trump’s holdings, seems like an unintended effect.

That said, I’m not surprised by this study’s findings. Coverage of Trump has an intensity that seems to far outstrip what is given for a president, even accounting for the various dustups he personally gets himself into.

But the essay feels a bit shallow in its hypothesis for this “obsession”. The author argues that this obsession is created by the NYT, partly as a response to mutual antagonism between them and Trump...and, that’s it? No mention of how Trump runs his administration far more via personal dictum than his predecessors. His generals and cabinet secretaries and chief staff members are constantly contradicted by Trump himself. Reporters have learned where power flows, and their job is to go straight to where the decisions are being made. Reporters would be absolutely fucking moronic not to focus on Trump, especially when he’s so open to sharing his decisions (in interviews and in tweets).

To put it another way: do the authors honestly believe that during the Bush years, the press wasn’t antagonistic towards GWB? That a greater proportion of stories back then focused on Cheney and Rumsfeld because those two were natural targets of obsession, versus Pence and whoever is filling in for Gen. Mattis?

To reiterate my point, has any of the past administrations since Nixon have had “acting” SecDefs and Chiefs of Staff for as long as Trump currently has?
> This does not change the fact that removable storage (or even storage that's accessible post board-failure) provides an additional margin of risk mitigation against hardware failure.

How much additional margin? If you have backups, you're covered against both failure modes; the only marginal benefit would be to recover the x hours of data since your last backup.
It’s not so different from 10.7 dropping Rosetta, which led to a similar scenario where upgrading your OS meant a bunch of old PPC apps could no longer run.

Again I’m not defending Apple, just pointing out that all of this has happened before and all of this will happen again with Apple.

If you value compatibility with old binaries highly, Windows is a much better platform for that than macOS.

If I were to guess, I would say it comes down to the U in USB, and power delivery.
An average human would realize it if you pose the halting problem to him. I'd expect the same from an AGI. To recognize such a problem and refuse to continue to devote time solving it.

There are counterexamples, such as AlphaGo which is all about planning and deep thinking. It also combines learning with evolution (genetic selection).
Even if you don't connect to the IRC network, even under Windows 10 MCC can still serve with minimal issues as a comic strip generator. That means that yes, you too can have your "own" Jerkcity if you want to.
When the touchbar first came out, I thought we'd see haptics in the second iteration. It seems so obvious that pressure-sensitivity and haptics could mitigate a lot of the weaknesses of the touchbar.

What I really miss is upgradeable RAM and SSD. Still using a 2010 MBP because I was able to upgrade it; that's no longer possible.
> Could a room full of software developers write a bunch of blog posts about random topics? Sure. But, as much as it may seem otherwise from the outside, that's not what a newsroom is doing. In fact, that's not even what the trade press does.

This is an accurate description of most of the news I see. For every piece of news that's actual original journalism, there's 2 articles that essentially amount to summarizing C-Span and another 2 that are essentially blog posts. And then there's the editorial section that really is essentially a collection of blog posts.
> He said that you just changed to be more careful about the lack of magsafe. Maybe I'll learn?

Having magsafe on my retina MacBook, with little kids in the house, may have been the best leisure hack I've ever enjoyed. The hack came from lack of anxiety about the kids tripping over the cord and bringing the laptop crashing to the floor, enabling me to simply set the machine down, walk away, and play with the kids instead. Now I would have to put the laptop somewhere out-of-sight in order for it to charge.

That's also why merchant sites have separate shipping and billing addresses. I bill at home and ship at work as I'm not at home during work hours when the courier arrives. And no, I won't install an Amazon lock to my door. If I can't ship to a different address then maybe the merchant doesn't want my money.

Also there are stores that do not ship to my country despite both being in the EU. They ship to New Caledonia (remote colony) or a poorer neighbouring country though. Maybe it has to do with lack of a VAT number and not giving a damn about getting one.
yes and not actually they are both good for the same reason, IE they don't hold value. This sort of gift is social signalling that you are willing to sacrifice a certain amount of wealth for them. Neither chocolate, flowers or diamonds have good resale value so you are sacrificing for the partners happiness.
It buffles me that software-wonder Docker raises so few money compared to unicorns like WeWork or some SF Startup.

I don't really understand what your point here is. Do you have any evidence that it's higher? I thought interviewing was supposed to be "random".

I work with a handful of people that did, actually

> But everyone knows that this is the truth.

Looks like the US rag industry is ripe for disruption: if you source old clothes & cut locally in Asia, you should be able to cut costs considerably (lower wages, less transport). Of course, the remaining non-trivial problem is getting US buyers to trust you.
The alignment problem?
I see it the other way around. Not changing for over 10 years (in this respect) is extraordinarily stable. When people complain about the site getting too political lately, by "lately" they do not mean a decade. Such perceptions of deterioration are distorted by things like recency bias and nostalgia bias.

The events you mention were from 2010 and 2013. I don't think it was all that different before 2008, either—the toddlerhood if not infancy of this place—because the site was governed by pg's tastes and those didn't change. It's just that there needs to be a bootstrapping period before the usual complaining about how X is worse than it used to be. I'm being oversensitive though!

Entertaining read. What a blunder the USB group has made with v3.x, it’ll all work out and eventually be awesome when every port and every cable just works and things charge fast but, almost every major feature of USB has had issues going back to first release. More reviews and articles should have a liars section.
Thanks for the recommendation! I hadn't heard of it bookwithmatrix.com.
Seriously. That guy is a stoned idiot who massively overestimates the insight of his high ramblings.
>can handle a high enough resolution/ rate that most human eyes can't distinguish better

Could you specify which resolution and refresh rate that is? Are we still talking about 1080p or this is higher?
I remember this TED talk many years ago where the speaker proposes that intelligence is maximizing the future options available to you:

We have lots of inherent biological biases like that.
Okay, so maybe don't opt in to them in the first place then?
Maybe. Yeah, human politics and justice systems leave something to be desired. But my worry was little bit beyond that. That the AIs would take all the meaningful work, discoveries and creativity away from us, leaving us just to amuse ourselves. Some people might be okay with that, but I don't think becoming pets is the best goal for the human race.

If the benevolent AI ruler(s) restrained themselves to allow for humans to flourish, then okay. Assuming it could be constructed benevolently.

If he announced that he is retiring and sailing around the world, I’m sure you’d find people asserting that his skills as a programmer couldn’t possibly translate to being a world-class sailor. Consider for a moment that he might just be very interested in AGI and wants to work on it.
I absolutely speak for them, who else will ? Clearly not people like you. I have the capacity to speak for them and so I do. And I will be the only judge about how much "caring" I do or don't do.
What do you mean? Plenty of computers now ship with no other connectors than USB-C. In other words HDMI is not ubiquitous

What I love about USB-C is I plug in a single cable to my laptop and I get keyboard, mouse, wifi, and monitor (4k 60hz)

At work I have a USB-C hub for my one cable to my computer. The hub has Displayport so I can use HDMI on a different device. At home my monitor does USB-C natively so my keyboard and mouse are plugged into that.
I loved my PocketCHIP, right up to when the software stopped getting updates, and the company ghosted everyone with hundreds of waiting orders.

I still have it, but getting it working again is a couple weekend's of work. (Which makes me somewhat doubt the simultaneous claims of mainline Debian _and_ based on the same underlying hardware as the CHIP.)

I love the form factor that these kinds of computers present. However, the promise of a decent production line will always ring hollow. Many of these companies have popped out, had a small run, and vanished, leaving the customer with a paperweight or a security risk.
Render Ecg Wave on Apple Watch
I am currently a master's student and about to start PhD in one of the top AI labs. I already feel mentally exhausted with all the indirect pressure tactics my supervisor uses like not responding to emails, withholding stipend for several months and so on. It's a disaster and I never imagined myself in this situation. I hope things change soon.
The announcement today has the potential to cut the number of years estimated (to reach AGI) in half, and I'm sure VC funds are DM'ing him non-stop right now. But we don't know which path Carmack will take, and as you rightly point out, current trends in AI is mostly ML/xNN's with a goal of turning data into profit (heavy focus on products/markets). Even those talking about AGI are fractured into different groups. Oddly, many in ML are talking about future abilities that are mostly defined by AGI research (even if they see AGI as a distraction. From his post, I don't think "product development" is a goal. Not clear what challenges or milestones he will set for himself (just having a better testing suite has become an AGI issue of late, so maybe he will contribute to that first).

Is it true that DisplayLink doesn't work well with Linux? Some years ago people were saying that the usb-to-monitor dongles worked well. A casual web search also gives this impression, with good support provided by the DisplayLink company.
Mojssanite (sp?) and zirconium stones have those properties as well, and cost much less. Some other gem stones are very hard to distinguish from diamonds without specific tools.

Does your sister have a preference for diamonds over finely cut zirconium (or even glass)? It’s likely not as simple as that, even if you and her try to rationalize it that way.

John Carmack Stepping Down as CTO of Oculus to Work on AI
AI is not here for doctors but for insurance companies, to charge you more if risky group is detected. There is the money and far lower risks than "helping doctors".

Humans are not AGI's. We're specialised in human survival, not general intelligence. We're pretty limited in intelligence in many ways, actually, and the environment doesn't support generality. Without a proper challenge an agent would not become super intelligent. The cost of developing such an intelligence would conflict with the need to minimise energy for survival.

Apple discontinued Time Capsule and their entire Airport line. The Time Machine software is still in MacOS, but de-emphasized and who knows if they'll retain it going forward.
While this is true, note that this special relationship between gradient, divergence, and curl only exists in 3D, due to the fact that 2 + 1 = 3, and the presence of the [hodge star](https://en.wikipedia.org/wiki/Hodge_star_operator) operator that allows us to convert "areas" into "normal vectors to areas". A curl is really a "infinitesimal area", which we then choose to interpret as "a normal vector".

This is captured by the [De Rham cohomology](https://en.wikipedia.org/wiki/De_Rham_cohomology), whose calculations are sometimes simplified by using the [Penrose notation](https://en.wikipedia.org/wiki/Penrose_graphical_notation) as outlined above.

Having used the notation, I don't think it helps for vector calculus. And I 100% agree with you that we should teach the intuition for div, grad, and curl first, but I wanted to bring to the attention of anyone who's never seen the "fully general" form of these objects as to what it looks like.
I went through 3 of them before finding one that worked (the first was buying before I knew the issue existed. The second was being impatient). I'm using this one on a Macbook Air. (https://www.hypershop.com/products/hyperdrive-duo-hub-for-us...). I'd prefer one that used a single USB-C connection (assuming that's possible) and that used a cable so it was useful for more than just the couple of devices that have 2 USB-C ports exactly that far apart but at the time, a year ago, that was one of the few choices. The good thing is it does work and I have it on 4k@60hz
Stories like these always add fire to the attractiveness of hedge funds, but I keep wondering whether it's still possible to have such wild success in this area these days. The field is so incredibly crowded now compared to a few decades ago, and every finance kid with some decent Quant background probably dreams of working in one
