There's more than one way to lessen effective resources being given towards something - inefficient allocation and cronyism isn't exactly a partisan issue. Perhaps we could leave behind the rhetoric about this being the fault of one side, and focus on how literally the entire country has been caught out as woefully unprepared? People used to have savings in this country, and it's not because corporations have squeezed it all out of them that they don't now - it's because people choose not to save anymore.

There's an outrage at people buyings masks and basic preparedness items now, but where's the outrage at hospitals who haven't even stockpiled trivially inexpensive (at the time) items like masks and gloves in preparation for a crisis? Did Trump force them to sell their stockpiles when he was elected? The blame game is a waste of enough time and resources when there isn't an international emergency - those politicians playing it now are practically criminal.

> How does Rust deal with long-lived objects that cannot be block-scoped (or request-scoped, in the context of a server for example)?

The issue is not really the scope, the issue is how many owners the data needs to have. A variable that needs to live longer than a scope, but only has a single owner, can be directly returned from that scope. Once you have the need for multiple owners, the most straightforward answer is "reference count them," but it depends on your exact requirements.

> A typical example here would be a UI framework, where memory has to be managed for the window and its widgets, and then the entire application is suspended until the next event.

GTK heavily uses reference counting. People are also investigating what a "rust-native" UI toolkit would look like; taking strong influences from ECSes. It's an open question if those architectures end up better than refcounts.
I've always enjoyed Amelia Wattenberger's approach to teaching D3. Her intro blog post (https://wattenberger.com/blog/d3) actually pushed me to purchase her book (https://www.newline.co/fullstack-d3). I found her on the last D3 post on HN (https://news.ycombinator.com/item?id=22480270).
If the string theory framework has yet to come up with a verified model nearly 40 years later, is it really that good of a framework?
It was never real good about backing up over a network except with hardware specifically designed to support that, like network routers that support Time Machine drives (or Apple's own Time Capsule).

I don't know that I'd say my own experience with Time Machine is perfect, but it's generally done what I needed to do, and has actually saved my bacon a few times by letting me restore individual files back to specific versions easily -- something I'm not sure an rsync-based solution would really provide (e.g., versioning for everything).
That's because broken theories can be used as frameworks to predict outcomes in coarser grained slicing of systems. Falsification is used when it comes to modelling but as a scientific test or rigor it's still important to pursue it because it finds the limit of your theories.
A sleep number bed with the app tracks sleep quite well, and you don't have to wear any sensors. I find it pretty accurate.

> If it is valuable, maybe browser is not the best medium for it.

Progressive web apps are not "the browser". It's a platform to ship apps using web technology that integrate into the operating system pretty like any other app, at least from the user's perspective. It works well enough on Android.

If you have to explain to your users all the caveats that such an app has on their platform, it just becomes pointless. If it becomes pointless on iOS, then it becomes pointless in general. You might as well go with a Web View app then.

Of course Apple has never been all that enthusiastic about PWAs, giving half-assed support at best. It was never a great platform to begin with, but now it's effectively dead in the water, at least for apps that are expected to work offline.

This is great! Thanks Mike!

When I've helped teach D3 it's always hard to get some of the basic concepts of joins and scales locked in. Mike gives a thorough overview of what is going on (and this is still an introduction) it's hard to teach when to choose what type of scale for people that might have forgotten some of their math lingo.

I've had some success in (maybe wrongly) demonstrating scales with mapping temperature in Farenheit and Celsius and how the scale is drawn if the domain and range are both 0-100 vs a scale of 0-100 and a domain of 32-212.

Curious if anyone else has any examples that help demonstrate some of these concepts based on their experiences!

I have a withings steel HR Sport (but the steel series are all the same tech). It's nice as a smartwatch to discretly read notifications, but I wouldn't recommend it as a sleep tracker. It's reasonable comfortable to wear at night (like a watch), but the actual sleep tracking is lacking. Often the last few hours get updated after I already woke up and picked up my phone. Also the sleep-cycle alarm always goes of at the earliest possible time for me and I can't figure out if thats the problem with the sync mentioned above or if I'm just always in light sleep at that time.

There is also the overhead of automatically unblocking a remote server during an unattended reboot. Reading the encryption password on a USB stick or fetching it through internet is a no from me. I think there are solutions about storing the password in RAM or in an unencrypted partition, but that's the overhead I'm talking about. I wonder how companies deal with that.

I doubt the information is really anonymized in the first place. Making it really anonymous requires will, skill, incentive, hierarchical validation and resources.

PyCM 2.6 released: Machine learning library for confusion matrix analysis
I literally just today had to kiss 2 months of some folders goodbye because TimeMachine utterly randomly decided to stop backing them up. First it decided to stop backing up the home folder; happened to catch that before reformatting. When later I reformatted.... some folders in ~/Documents were empty. Ironically important ones (“archive - important” :( ). I sleuthed through logs, exception rules, everything: no rhyme or reason, no explanation. It just didn’t back them up.

Pure luck that the last reinstall was 2 months, and that version did back it all up. Lesson learned: don’t trust Time Machine. It’s a nice to have.
Maybe. Still not switching away from Firefox though. I have Chrome installed because WebRTC is a lot better and teleconferencing needs have shot up recently, and because I lock my phone away in a Kitchen Safe and use 2FA with Authy the Chrome app, but Firefox is my daily driver :)
I suspect keeping a sleep log is more accurate than most other methods, particularly for anyone who has had a chance to calibrate estimation with a sleep study. One exception might be trackers with electrodes like Dreem (I have not tried it and like many it is a cloud thing that becomes completely useless if the company goes away, which many have).

I find the accelerometer based trackers to be completely useless. I haven't tried a combo pulse/accelerometer type that should be better but I am doubtful.

I use a Contec CMS50I pulse oximiter on occasion in addition to the sleep log. I can determine when I first get to sleep based on my pulse but otherwise it doesn't help other than that I can tell when I take it off. My estimates of when I get to sleep have always been close, although I'm guessing this might not be the case for most people.

For the sleep log, I record when I get in and out of bed (rounded to 15 minutes), when I guess I get to sleep and wake up (rounded to 30 minutes), time in bed, estimated sleep, any medications I took before bed, time I use light therapy in the morning, and any notes I want to remember about how I slept (or anything else since I don't otherwise keep a journal).

I'm not convinced sleep tracking is actually a good idea for most people (or necessarily anyone as a regular thing). The negative of a sleep log is that thinking about when you get to sleep and wake up enough to make a guess will wake you up a bit. The trackers mostly don't seem accurate enough to be all that useful. I'm not sure what most people would do with the information; it seems mostly helpful to compare different sleep medication or practices or to convince yourself that you are getting more or less sleep than you think. I suspect that just writing down in the morning how well you think you slept, how you are feeling, and maybe when you got in and out of bed might be at least as useful as anything more elaborate.

> A recent patchset proposed for the Linux KASLR randomizes not only the kernel base address, but also reorders every function at boot time.

(I assume this just puts each function in its own section and reorders them at boot?)
I recall reading a paper that found that compared to clinical sleep study equipment (you know, electrodes all over your head) that most devices were random at best in terms of measuring REM sleep. I did a lot of research when a friend went all in on sleep monitoring and wound up worse than when he started (worrying over data).

I didn't exhaustively research but based on un-biased available science I found at the time, any investment (in devices/apps) was not worth time and money. Maybe that has changed.

See https://www.nytimes.com/2019/07/17/technology/personaltech/s...

"For a person to be worrying about their sleep stages is like being worried about the gas makeup of the air you're breathing in," he said."

""From EBE analysis, ŌURA ring had a 96% sensitivity to detect sleep, and agreement of 65%, 51%, and 61%, in detecting "light sleep" (N1), "deep sleep" (N2 + N3), and REM sleep, respectively. Specificity in detecting wake was 48%."

Specificity in detecting wake was 48%! If this was a medical test, it would never be approved by FDA."

The NYT article summed up reality for most nicely:

"Dr. Vallat told me that if I really wanted to get better sleep, I should simply try to sleep and wake up at the same time every day — that would help my brain learn how to build a structure for optimal sleep. He also advised making the bedroom a cool environment (about 68 degrees) and as dark as possible; avoiding alcohol in the evening; not checking email or social media right before bed; and asking myself each morning when I woke up, "Do I feel refreshed?""

Stop drinking and watching tv/screens and go to bed on time... don't need an expensive ring or watch to tell you this...

Falsifiability is not a political cult bugbear. There are very good reasons to pursue it that you can't just handwave away like that, IMO.

The psychology and economics examples are very ironic to me as I see the main issue with the effectiveness of those fields being precisely the lack of falsifiable results in their research. Its prone to a large body of bogus theories being used to the detriment of the field.

> There’s a pretty easy solution to this problem if you don’t want to tracked.

- That's assuming enough people know and care about it. You are tracked by the sensors carried by others too. And even if you are not, you live in the society built around the collected data anyway. It affects you.

- it's a twisted point of view. I should be able to enjoy the benefit of technology without having the threat of my own fellow human using it against me. This is bullying.
I would guess they have built something into chrome that gets even more data that isn't user-agent based.

UA has a lot of limitations and is fairly easy to work around giving data to for power users. I would imagine Google didn't want to keep playing around with that.
I don’t think there’s any indication that heart rate and movement monitoring can provide any robust insight into sleep cycles, and in my experience struggle to even understand sleep start and end points. Seems like you need to go to a device with an EEG to get decent information, I’d be interested if there were studies dealing with this question though.

Not for a technical reason, but they had a reason: they provided no support or guarantee that Netflix would ever work on Linux + FF (Ubuntu + Chrome was guaranteed) and they didn't want any support calls for something that they wouldn't help people with anyway.

A lot of stuff gets blocked for this reason. The company doesn't want you calling them because HD video doesn't work on Firefox even though you pay for HD quality, they do not test or guarantee Firefox compatibility in the slightest and yet they have to talk to an angry customer now. It makes business sense to redirect people to supported use cases when you know your product probably won't work as intended otherwise.

You don't have to agree with the decision (and you can always cancel your membership if you do) but they had their reasons.

I haven't seen Withings Sleep mentioned - https://www.withings.com/us/en/sleep .

This one is basically "set it and forget it". You put it under your mattress and calibrate it, then it tracks automatically.

I like it because I don't have to bring any gadgets into the bedroom, or remember to turn on tracking.

It seems pretty accurate from what I've seen so far, although I don't have anything to compare it to. I've found it very useful for testing various sleep interventions.

Maybe we should learn how to, because this may not be the last pandemic we face.

Retailers and citizens can't pay rent. Landlords only need that money (per se) because they owe money to banks via mortgage, or the government via taxes. So government should order the banks to halt collections on real estate, and government should halt collections of property taxes.

Banks might go under? Have the fed print them money. Governments can't afford it? Have the government print money.

Inflation due to increased monetary supply? That's where my idea ends. Perhaps instead of the printed money being a gift, perhaps it is a zero percent long term loan.

Landlords need the money to live? Give its employees the same cushioning we should be giving all citizens through the pandemic.

I second this, Autosleep has amazingly fitted A LOT of data into their screens, a bit surprising for the price of it.

Screen sharing works in many video conferencing software packages but OBS gives you a lot more options. Frequently on Twitch you'll see the game taking up most of the screen, a video of the host overlayed on the video, with smaller areas showing parts of other windows, text, and videos. It also lets you save any number of these scenes and transition between them smoothly.

I was actually trying to get this working for myself because I'm doing a presentation in a few days and I'd like to be able to swap between myself full screen, and then either the slides or another piece of software with my face in a smaller area. If a "virtual webcam" tool was available for OS X I would be able to pipe that into Zoom.

I could just do a screen share and switch back and forth but I want to do something a little more polished.
I used beddit (https://www.beddit.com/) a lot, but since they were bought by apple there is not really any updates for app or hardware. It works like withings sleep where you don‘t wear anything, but it needs Bluetooth connection to your phone the whole night because it doesn’t have any storage.
