In addition to what lmm mentioned, giving to patreon usually comes with some sort of perk or special content, and it's also a subscription by default which I imagine isn't the case with a donate button.
Everyone says strings in java are immutable, yet you can still re-assign to string variables. It really is up for debate.
There is no doubt that quitting smoking or nicotine products is incredible difficult for some people.

The worst thing about nicotine is how it alters reality so much. It’s like a science fiction mind control nightmare. From the outside I see people standing in the cold with a burning bit of crap in their mouth. To them it is among the most important thing in their lives.

It is why I think we should ban commercial sale of nicotine completely, whether through smoking or vaping. I’m not directing this at you personally, but I’m sick of hearing mind hacked smokers complaining about how hard it is to quit and how good their lives were standing in the cold with a burning piece of crap in their mouth. You want to grow your own tobacco and smoke it, be my guest. But letting someone make money from hacking your brain permanently? That is madness. If the brain was a software product you would urgently patch the nicotine receptor as a critical vulnerability.
I think your anecdote only shows how much discretion the immigration department has in enforcing the law. That same discretion could easily go the other way if someone were to embarrass Japanese authorities.
Au contraire, they’re some of the best textbooks I’ve had the fortune of reading! :-)

They make the student work (participate actively in your own education), which I’ve noticed that American textbooks (at least modern high school & college textbooks) seem loath to do. I don’t know why — you don’t develop what you don’t exercise!
Can you elaborate? I am interested in knowing about these programs for my son.

It wouldn't be that major of a project with today's equipment. Just attach any modern camera. However, most of those missions were designed around equipment available decades before they are actually being used, so they are outdated by today's standards but were high end back then. Also, B&W sensors with filters have so much more resolution than dividing by the RGBG pixel arrangement. Maybe Carl Sagan will have had enough of an impact that future mission will include a "regular" camera specifically for the function of making everything more human relatable.
Wirecutter has a good guide: https://thewirecutter.com/reviews/best-robot-vacuum/

But honestly, actual needs are going vary by what your house is like, who lives in it, how they live, and what their standards are. And on how your habits and preferences adjust as you get used to what they can do for you.

At the end of the day, none of these are as good as manual vacuuming. But they're way better than not vacuuming. I'm sure it's frustrating to have to just try one and see, but I honestly don't think there's a better approach.

0.8% is still an underestimate. The average size of a TCP packet in real networks is about 500 bytes, due to the ACKs. And timestamps need to be present in the ACKs too.
We have an Ecovacs Deebot and it can get in amongst a mess of chair legs quite well, even when the gaps are barely wider than its body. Where it's trouble though, as you say, is having the kids keep the ground bot-ready - toys/crafts everywhere. Best combo is probably a bot and then a stick Dyson, I suspect.

Generalized door-to-door self-driving is decades away. And when it's here, the average person isn't going to be renting out their car. If the economics work, cars will come from centralized rental services like... ZipCar. Maybe car manufacturers will decide they want to rent cars directly but they could today and don't.
But they are not on the federal level, with the benefits and disadvantages of this. The benefit is that they don't get dragged into partisan politics and have their agendas changed every four years. The disadvantage is in reach and scale. In some countries they can get the top 2000 middle school math students across the country into the same campus. In the US it's more like the Top 100 students in Virginia, which is a different experience.
I think the reasoning is that the incentives are flipped. Capitalist school gets more money the more you stick around. Communist school spends more money the more you stick around. One has a perverse incentive to get as many people to pass as possible. The other has a perverse incentive to get as many people to fail as possible.
They basically said just that in their statement:

> This decision was not made lightly and consisted of several other factors beyond the financial ones. Prior to the pandemic, we had completed an in-depth performance review cycle and deployed a new company strategy – both exercises highlighted the need for different skill sets moving forward.

It was this combination of economic uncertainty, performance reviews and a shift in strategy that prompted us to make this change.
Somewhat cynically, I think the point of many textbooks is to make money for the authors.

There is no reason why a calculus book needs to cost $200 (in the 1990’s) and get refreshed every 2-3 years. That subject has been known for hundreds of years and they rob poor engineering and science student of that $200.

Sorry, I just have a bad taste in my mouth from crap like that in undergrad. Not saying you’re wrong, just think it’s more greed oriented than we’d like to think.

That's a really interesting document.
Yeah, theirs is far less obfuscated than most fraud/bot detection libraries I've seen. I believe almost all of the JS code I've seen from companies that primarily do fraud detection and web security is pretty heavily obfuscated. Here, it looks like Stripe.js is doing much more than just the fraud stuff - this is their client library for everything, including payment handling.

I haven't analyzed it and can't say this with any certainty, but my guess is that you're probably right: they're focusing primarily on backend analysis and ML comparing activity across a massive array of customers. This is different from smaller security firms who have a lot less data due to fewer customers, and a kind of sampling bias of customers who are particularly worried about or inundated by fraud.

They may be less interested in suspicious activity or fingerprinting at the device level and more interested in it at the payment and personal information level (which is suggested by articles like https://stripe.com/radar/guide).

Pure, uninformed speculation, but it's possible that if they get deeper into anti-fraud in the future (perhaps if fraudsters get smarter about this higher layer of evasion), they might supplement the data science / finance / payment oriented stuff with more lower-level device and browser analysis, in which case I wouldn't be surprised if they eventually separate out some of the anti-fraud/security parts into an obfuscated portion. (Or, more likely, have Stripe.js load that portion dynamically. Maybe they're already doing this, even? Dunno.)
Depends on the initial pay. Not everyone on the Internet is making $150k.
There are four large .gif files. I believe the one you are referring to is 2.6 MB and named `Duo_540X540_TransparentBG_3s_splitscreen_05.gif`, with a split screen comparison of what it would look like at 30kbps. The overhead is the graphics of the "montage", I figure.
I'm 28. We emigrated to Australia(from Russia) when I was in approximately grade 3-4. I basically did no mathematical study for 4-5 years, the system was that far ahead. From family in Russia I hear that ridiculous amounts of homework(2hrs daily if you're on top of everything) is still a thing for young children although there's all sorts of strange pro-putin insertions in the curriculum but ultimately I don't know, it seems like Russia as a whole has very quickly lost the few positives the Soviet Union brought. I felt the quality of teaching was much better aswell. It seemed like many Australian teachers did not fully grasp many of the concepts themselves. From what I understand the American curriculum is even more relaxed so I'm not entirely sure where the above commenter gets their information from or if they're being entirely honest.
Theoretically I'd agree with you. And tbh that's how most of us saw teams before this situation. It looked like yet another over engineered enterprise "communications" tool that was bound to have a lot of half-assed hard corner cases -- so we just ignored it and hoped it would just go away.

Now that we've all been forced to use it and come to terms with it, the deep integration is extremely powerful. In fact the couple areas within it where the integration is still a little thin stand out because the workflows around those end up being a bit fussy.

It can be difficult to explain to somebody who doesn't use it, but it's not something Google has sorted out yet, not even close. It's like saying "I have all the ingredients for a cake in my pantry, so they're all together, it's basically the same as having them together in cake form."

Google has all the pieces to do something even better than this, but their corporate culture is like a hammer shattering all the pieces into different bits with only the most superficial connections between them. They may be allergic to even try given what happened with Wave, but even a half-decent copy using the building blocks they have would be pretty great.
I feel like this sort of comment can only come from somebody who's never had to deal with operations.

When you have a lot of users (especially when they rely on you to get money from you!) even 0.1% of them asking questions and having difficulties is a huge work generator!

It's not "oh it's easy to write a for loop". It's "my for loop now has 20 non-orthogonal options, and a user is saying we emptied their bank account and now we gotta make sure if we did". Also a content host, a CMS, and reporting software for taxes and the like.

I mean I bet you could get away with 100 people or something for this but there's _so much_ that can go wrong and would require lots of intervention.
You are probably really gifted. I don't think this is a typical experience, that a fourth grader in any country who doesn't do much homework knows most of US high school math.
Besides the Create, iRobot also left an easily accessible serial port connector on various series of Roombas, and published the interface protocols, and sold a cable, for education/hobby purposes.

A lot of general info about this is collected in the documentation for a particular library that uses it: https://www.neilvandyke.org/racket/roomba/

I wrote this library when I found a Roomba 400 in a Goodwill thrift store for $20. When, if living in the future of having your own robot vacuum cleaner was not cool enough, hey, what's this mini-DIN connector for... :)

(Also on the topic of liking iRobot: That same $20 Roomba was also the first time I met an iRobot person. I eventually bought a used 530, and was giving the 400 to a friend. Since I owned robots but not a car, I strapped the Roomba's retail box to my trusty little luggage cart, to meet my friend for lunch. Afterwards, as we're walking along the dirt path along a bank of the Charles River near Harvard Square, rolling the Roomba behind us, this jogger comes running along, and then stops. Turns out she worked for iRobot, was super-nice, and was tickled to see a vintage Roomba in nature.)

That is probably not that intentionally. That is just a result of my own observations.

I have a similar combination, the i7 with a 240, and I also think they're great. I can't even remember life before daily automatic floor cleanings. I think you're right about iRobot's competition iterating more quickly, and I'm also concerned that they might get left behind. Another concern is their pricing. They're clearing trying to establish their robots as the premium models in the market space—ones that "just work"—but the price tags are astronomical. Their two flagship models, which were advertised as working best in tandem, cost nearly $2,000 together when they were first released.

If prisoners had a single test, and the false negative rate of the test is 25%, or if 25% had recovered, that would mean nearly 100% were infected. That would mean a very high R0 (believable in highly crowded conditions), and a high R0 would mean than most inmates had been infected recently?

Before anything can be implied about population death rate:

1. need to wait about 3 weeks

2. need to know the age demographics

3. need to know if at-risk inmates were isolated

Edit: on reflection, R0 itself doesn’t mean anything about how quickly people get infected. I think a fast rate of infection through the facility could be implied.

The fact that Zuckerberg and Facebook are making this bet, using the data they have, suggests that the Modi era will continue for quite a while. Ambani’s fortunes are closely tied to Modi.

The patreon podcasts I listen to have all said they're sorry to see people go but know money will be tight for many, and that if we can stand remote recordings, they'll be making just as much content as before.

Not sure if they're all just spooked or if they've seen hits already.
It’s an empty, pointless prediction; easy and uncontroversial to make now when things look grim (for everyone), and zero cost to you if it turns out to be wrong.

I know little about the details of Lambda School’s business, but they seem like they’re in a good position to do well in an economic downturn and recovery, if they stay focused and prudent, which seems to be exactly what they’re trying to do now.
Addendum: I have no clue if they actually are using fingerprinting or supercookies. I just know many anti-fraud service providers do.
> I have a metric shit ton of Apple stock after being there for several years. At least until I hold the stock for a year and only pay capital gains on it.

Genuine question for anyone who gets RSUs at a public company like this. Why do you keep your $FANG stock when it is granted?

You've already paid income tax on the basis, which is the closing price the day you got it. The year long timer for long term capital gains tax starts the day you get it. So vesting $X of grants on your vesting day and holding is equivalent to just buying $X of stock on any old day. As a bonus, you're already heavily heavily exposed to that stock because A) they're your employer, and B) presumably unvested RSUs coming in the future.

>If they got rid of the excessive whitespace at each side of the chat and used libnotify like civilized folks I'd be super happy.

I wouldn't hold my breath. They use the same custom notification on Mac os and even on Windows.

Oh, and on Linux, have you tried using it with a tiling wm ? The notification gets its own regular window. The first time it happened it was quite jarring to have it fill half my 32" monitor. Even since that happened, I've went back to using it through Firefox, which honors the system notification setup.
No. It's well worth your time to read the whole piece.
You'll never get self service out of a company that works this way. But it's not all bad.

Behind the salespereson is an engineer who knows the product well and is paid to impress you. Use that to your advantage. Tell them what you want and let them put on a show! They are very likely willing to invest multiple engineer-weeks in helping you build a POC in their environment, fielding your questions, etc.

The initial contact may start from the assumption that you're a bureaucrat but once it's clear what you're interested in and what kind of evidence is going to be persuasive to you, a good sales process will play ball.
Thank you for your feedback. I am one of the authors of this paper.

I don't think the paper gives any hints on us dividing universities into classes and comparing. Would love to know how you reached that conclusion.

At the same time, yes, we could have divided universities into different classes: research vs liberal arts, this vs. that state, big vs. small size, etc. These are all trivial groupings but none of these would change the conclusions of this paper. For all practical purposes, we could easily have replaced the university names with labels like U1, U2, ... and still the conclusions would not change. What matters is how a weight-based composite index can be gamed and the paper does show that in multiple ways. Pls review the ILP formulations yourself and run them on the dataset of your choice.
Surely two Uber rides would be cheaper than that.
It wasn’t just marketing. Historically, a kilobyte was 1024 bytes in memory contexts where everything was based on powers of two but nowhere else. This was obviously confusing because everywhere else used kilo as 1000 — a 420MB hard drive would have been measured in units of 1024 for capacity and 1000 for transfer speed.

When the SI units were standardized in 1998, it helped drive manufacturers advertise larger numbers but it also rectified this accident of history where a standard prefix had been used with a non-standard definition in only one part of computing.
> Llvm makes some questionable choices about how to do SSA, alias analysis, register allocation, and instruction selection.

Do you mind expanding more on these points or directing me to some places where I can learn more about them? Compilers are a fairly new field for me, so anything I can learn about their design decisions and tradeoffs are worth their weight in gold.
Are there similar retro-UI systems for other older interfaces? While I don't have that much nostalgia for Win98 myself, I could see how it could be cute to have similar systems for classic (System 6-7) Mac, Amiga, etc. I've seen websites that try to go for these looks, but I think they were manually done.
Rather than paying for parking, herds of cars will slowly cruise local streets, awaiting summons.
Years ago I worked on a project to do exactly that for local development ordinances. Try to boil down the intent to the simplest version of rules that would encompass that intent, while stripping out all the rest. It got some local interest, but there were too many local interests that each wanted everything simplified except for the couple rules they specifically benefitted from in some way. So it didn’t go anywhere.
Did you read the whole article? I didn’t get the impression Joel took any stance. It felt more like “look this is how it is, and here’s why.”
That was on laptop cpus though. Even if Google optimized the encoder to accomplish this on mobile processors, a fully utilized cpu would drain batteries so fast that the user experience would suffer.

Wow! Very interesting news. (Bad for us consumers ofcourse.)

Reliance Jio is focusing on vertical integration by even building and rolling out their own 5G tech (https://content.techgig.com/jio-develops-in-house-5g-tech-ai...). And I am sure they plan to expand to other countries in 5 years or so. It will be very interesting to watch how they change the telecom industry in these countries too, in the future.

Speculating because I don't know the details, but feels like Facebook got the better end of the deal - FB bought WhatsApp, a messaging platform, for $19 billion. $5.7 Billion for 10% stake in one of the largest mobile network in the world sounds a real bargain ... right?
I have been using it to supplement my son's maths lessons, using some of the problems the author gives as examples and creating more in similar style.
As many good things as I say about it, there's still some rough edges.

- Starting a group telecon from a channel doesn't seem to exist. You have to start a chat with the same people and then you can start the meeting.

- The screensharing selection interface is kinda wonky and doesn't show certain applications, it consistently won't give me an option to show Excel, but every other thing I have open is visible (MacOS).

- It gets hung up sometimes if people paste lots of images into a long chat.

- It needs better management of old chats, channels and so on, for example there's certain old chats from last year when we were first testing it that I really don't need around anymore and I'd like to get rid of.

- The notification system is a bizarre mess, I can't quite seem to find the magic combination that turns off notification sounds, but plays a sound when somebody calls me for a voice or video chat.
