Can anyone recommend a good sleep tracker with a smart alarm?

I had one of the original Jawbone Ups, and it was great for this. Sadly, it didn't last forever and now they're discontinued. I did a solid search about a year ago and couldn't find anything that suited - essentially a sleep tracker with a smart alarm that's not tied to a mobile phone, and ideally with the ability to wake via light as well as noise.

(I get that the Apple Watch offers options, but it never seemed sensible to use a) use quite a bulky watch to sleep with, and b) choose a watch that would ideally charge overnight, to capture sleep data.)
Right, I mean memory is sufficient for most sorts of things, but if you want to do the sort of retrospective debugging and analysis the article talks about, you either need to be born a savant or rely on some external system. Eventually, when we have good neural interfaces, I think this will be done automatically, but that may or may not happen in any of our lifetimes.

Natural selection is good for ensuring you make it to a bit past reproductive age, but for everything else it's really hit-or-miss. As one would expect. We're just the first known lifeforms that seem to have an imperative beyond replication.
Not sure what you're talking about. You can run whatever software you want in iOS. You don't even have to have built the app yourself. We do this all the time where I work - we create our own apps we distribute to our employees and we receive apps from vendors that aren't distributed through the app store. Yes it's a different process than we're normally accustomed to but it's certainly doable.

Bottom line - no Apple approval is required to run whatever software you want on an iOS device.
It's not fine, but it's certainly to be expected.

BackInTime is an excellent alternative to TimeMachine! Searching old backups is literally just browsing directories. I've used it for years until Ubuntu started nagging to use the included backup utility.

Once you make the first snapshot, BackInTime is much faster that the recommended backup. Where the native backup shines is encryption and file splitting: you could backup to a cloud drive and not worry about strangers looking at or extracting metadata from your personal files.
I believe the Time Machine is a white elephant, a relic.

It ought to be able to do these things as good as (if not better) apps like restic, borg, backblaze etc : dedup, compression, unlimited versioning (at file level), integrity checks, granular search/restore, possibility to set a cloud destination (at least iCloud).

But a lot of these things it doesn't even try to.

It is very hard to understand what dgit really does when its using terminology (decentralized git) clearly incorrectly.
Presumably you'll grab the dimensions (could cache after first load) and then render dynamically based on that. If you're doing some sort of if statement on the server to deliver content based on screen size you're probably doing it wrong. Obviously I can't speak for every mobile user, but for myself, it's infuriating to have a completely different set of functionality on mobile.

What if I have flu and that corona virus which do not affect humans. People will think I have COVID.

Edit:

The test developed was done against 75 people with various other diseases as listed below to find out the false positive rate. With the 75 samples (having listed diseases), the false positive rate was 0.

I hope we didn't any other major common virus, and also is 75 a big enough number to say that the false positive rate is definitely 0?
> We faltered because of our failure to consider risk in its full context, especially when dealing with coupled risk—when multiple things can go wrong together. We were hampered by our inability to think about second- and third-order effects and by our susceptibility to scientism—the false comfort of assuming that numbers and percentages give us a solid empirical basis. We failed to understand that complex systems defy simplistic reductionism.

This puts words on what's been frustrating me the most when talking about this issue with some of my friends and on online boards.

I haven't considered it before, but when I think about it now I realize that I see a clear distinction among those I have been talking to between those who have done an MSc or higher in an area such as physics, mathematics or computer science.

(I don't mean to imply that those people are in some way more intelligent, but it goes to show how extended practice of systemic thinking and problem solving can prime us to better understand complex issues in general, or at least get a better approximation for our uncertainty and how that relates to risk)

I also think there's the simple fact that the vast majority of even educated people have a hard time understanding simple statistics.

There's been this notion that "Japan has handled the outbreak well" or, among the conspiratoricals, "the government is hiding the real numbers" where my take is that the data is just not there to make any kind of conclusion either way yet.

And this is hardly a US issue - we see the same pattern most everywhere.
creating models that work with all known physics without predicting new phenomena that can be tested seems very similar to what we did with epicycles.

i.e. it is just creating a complicated system to "curve fit" known data.
> QA: What, as an ordinary citizen now, frightens you most, would you wish, most could happen, to stop the panic at least.

> YH: I think the worse thing is the disunity we see in the world, the lack of cooperation and coordination we see between different countries, and the lack of trust, both between countries, and also between the population and the government. ¶ This is basically the payday for what we've been seeing in the last few years, with the epidemic of fake news, and with the deterioration of international relations. ¶ If you compare this for example with the 2008 financial crisis — which is of course a crisis of a different kind, but there are similarities — in 2008 you had responsible adults in the world which took a leadership position, rallied the world behind them, and prevented the worst outcomes. But over the last four years basically we've seen a rapid deterioration of trust in the international system. The country which was the leader previously, both in the 2008 financial crisis and also in the last big epidemic, the Ebola epidemic in 2014 — and that country is the United States — now it is not taking any kind of leadership position. Actually since 2016, the current administration has made it very clear that the US has resigned its role as world leader, it made it very clear that the US has no longer any friends in the world, it has only interests. And even if now, the US — which is not doing so far — but even if it will try to assume a leadership position, nobody would follow a leader who's motto is “Me first.” ¶ So what really frightens me is the lack of leadership and cooperation, and what people should realize, is that the spread of the epidemic in any one country threatens the entire world because of the danger that if we don't contain this in time, the virus will evolve — that is maybe one of the worse problems with this kind of epidemic — is actually a rapid evolution of the virus. We saw it before with the 2014 Ebola epidemic. It actually started, the Ebola epidemic started, with one genetic mutation in one virus in one person in West Africa, which turned Ebola from a relatively rare disease into a raging epidemic, because this single mutation increased the contagiousness of the virus four times. ¶ Now this could be happening right now, somewhere in Iran, or in Italy, or in anywhere else, and wherever it happens, it endangers the entire world. ¶ Humanity needs to close ranks against the viruses.

Yuval Harari then goes on to describe the second thing that scares him the most: The rise of authoritarianism through governments taking advantage of peoples’ fear about the virus.

The issue is elsewhere: you need to pay your developers to develop the second app. You would most probably need to bring in one more team, for each native platform.

Will you get new users from that? If yes, they will pay for that (in principle). If not, just some existing users would migrate? Then you just increased your cost without increasing your revenues. So you would need to gain enough new users to make it worthwhile.

* * *

In a nutshell, it is the same reason why Adobe won't port their apps to Linux. They already have all the users that need their software, and while it would be nice for some of their users to migrate, it won't bring anything to Adobe.
You linked to a login-walled article where the section above the fold does not clearly make your point. The subtitle "hidden from authorities" would imply it wasn't authorities doing the hiding. You could have clarified this point in your initial response, instead of leaving an ambiguous sarcastic remark.

>if you do indeed live in such a state and are hoping that information freedom and democracy is enough to protect you and yours.

Never said that. I do think information freedom is preferable to the alternative.
They are all garbage, without monitoring brainwaves you have essentially zero useful information about sleep quality/duration/stages. No amount of accelerometer/heart rate data is going to accurately reflect your sleep stages, regardless of what marketing spiel you read.

For a brief time there was a consumer product "Zeo sleep monitor" which was a legitimate EEG-style brainwave headband you would wear to sleep. From what I recall, comparing it's results to those of in-lab sleep studies, it was fairly accurate.

Sadly they went out of business as it was a fairly niche product and pretty expensive.

It's interesting to see our desire for blame kick in.

If Earth was hit by an meteor two weeks ago, or if there was a major earthquake in California, I'm sure we'd see similar blame coming from the media.

Someone that has been warning of meteors or earthquakes for two decades would get on TV and talk about how negligent everyone in power is for ignoring their warnings. Agencies would argue that with more funding they could have responded earlier.

Everyone who already hates Xi Jinping or Trump or Johnson or Pelosi will attach new narratives to their favorite villain blaming them for the event and the response.

Maybe sometimes shit just happens, and we should skip the blame game and focus on improving our response.

The best thing about this story was that it's was self-reflective on the media's 180 on this issue. That's something I don't see often in media. Just four weeks ago all the major media outlets were downplaying everything, and now those same outlets are placing blame for not taking things seriously on everyone but themselves.

The federal government has unmistakably (maliciously at this point) failed us in our greatest time of need. States are now acting fully autonomously and some in open rebellion towards the federal government to support their infrastructure. Every single American is affected by this.

Long term, I see regional (multi-state) partnerships evolving into regional governments. Texas, Cascadia, etc. We may be at a turning point where this won't be a 'nutjob' idea anymore. Trump's election was a cry for help to reorganize our system (drain the swamp).
For many it’s usually “back to IE11 on the locked windows 7 workstations of all financial, insurance etc. institutions I want for a client.”
a search term or a regexp only matches on a single line. i think what op is asking is the ability to match multiple terms across multiple lines.

eg. i want to find all notes that contain the terms "linux" and "webserver" in any order anywhere in the note.

it may be possible to write a multiline regexp to do that, but it's not trivial, and this would be a common use case
This is almost certainly true in practice, but it's a big risk, compared to the risk tolerance that we usually engineer into crypto. For comparison, suppose someone was suggesting: "Why not use 80-bit keys instead of 128-bit keys? No one in the real world can brute force 80 bits, and we'll save on storage." Yes, that's true, but it's taking a relatively large risk for relatively little benefit. Hardware will get faster over time, and an extremely high value target might justify an extremely expensive attack, etc etc. We prefer 128-bit keys because then we don't even have to consider those questions. I think timing attacks are similar: Yes they're very difficult in practice, but they raise questions that we'd rather not have to think about. (And which, realistically, no one will ever revisit in the future, as hardware evolves and new APIs are exposed.)
Much of D3 doesn’t require the DOM, so if you want to do things like generate SVG on the server, you can use d3-shape, d3-scale, d3-path, and the like as-is.

If you do want to use the DOM on the server, you could use JSDOM. d3-selection and d3-transition use JSDOM heavily for unit testing and it’s worked well, but I’ve never used it for server-side rendering.
Your demo page is 3.23 MB. ~500KB is javascript, ~500KB is CSS and another ~400KB is web fonts. The parts database is 24 KB. That's certainly not the first place I would look for an optimization target, even for customers with very large parts databases.
That's not really bare metal either. You should be directly manipulating the electrons flowing through the material :)
I've been going to large conferences since I started my career 20 years ago. When I was a junior engineer I found the sessions very informative, but as I developed more experience, I always got the most value hanging out in the hallway after sessions or the hotel bar at the end of the day.

I've tried "going to" a few virtual conferences and they're basically useless. Losing these physical spaces to gather and discuss will be a huge blow to learning and collaboration.
I'm not suggesting trying to cure or prevent the disease, but to promote its symptoms to emerge in asymptomatic carriers so that they can self-isolate.
anyone who is running git is _already_ running a distributed git node which is not managed by a single central entity.

there are many _many_ web based git apps (many of which provide github like features) that anyone can, in theory, set up.

why would I want to set up a sia node instead?
Novel Hybrid Continual Learning Algorithm Counters Agent Forgetfulness
Yes, but if you can find a chip with public documentation, it's a well-defined initialization sequence.

I learned assembly on TI's AM335x "Sitara" series and it was great, mostly because of the BeagleBone- it has onboard JTAG-over-USB, meaning you can single-step your way through your bare-metal code, set breakpoints, etc.
So "decentralized" is a synonym for "distributed"?

Suppose I mount, under /path, some kind of distributed filesystem whose storage is replicated among many servers (for fault tolerance, availability, and performance) and then store a git repo into /path/to/repo.git.

If I clone from this, so that my origin is "file:///path/to/repo.git", is that then a decentralized git remote?
Yes, but the value is to provide that in exchange for money, and ostensibly only to law enforcement agencies and similar organizations. (If you try to sign up on their website, it says "Clearview is available to active law enforcement personnel" and that you need to apply for access.) If you're a random citizen and can get the same data, especially for free, the value proposition breaks. And the privacy implications would be worse.

So, I get why they ask for ID, even though I also get the reluctance to give them your ID since it could help tune their system.
I dunno, if one of my coworkers had put in the work that OP did, showed me the results, and asked my thoughts: if I didn't have enough information I'd ask for more. If you're telling me you don't have enough information to assume some basics about the setup (I'd look at that and assume it was a modern Intel or AMD CPU just based on the throughput) - then how does he have enough information to dismiss the findings as "then this is from lack of understanding on your side."

You can't have your cake and eat it too.
> what percentage of us had the forethought to divest our retirement accounts at that time?

What percentage of us had access to intelligence information saying how bad the situation could truly be?

What percentage of us have jobs in which we are responsible for other people's lives and the stability of our countries?

What percentage of us were getting briefed by the CDC and other related agencies when this whole thing started?

You cannot compare the public's reaction to government officials' reactions. It's their job to be on top of this stuff, react appropriately and guide the public through times of crisis like this. That's why we call them leaders.

However, you can compare their reaction to the reaction of the leaders of other countries. How did the US government react to this pandemic compared to South Korea, Singapore, Taiwan, with months of additional time to do so?
OfferUp and Letgo to Merge
Really excited to share pion/ion! It is a distributed RTC System written in Pure Go and Flutter. It can be used for video conferencing, live streaming and most other media streaming problems. It has a lot of interesting features, but the ones that seem to excite people the most are.

* Distributed by default - Designed to allow running different workloads and scaling them out as you need

* Flutter and JS SDK - Ready to be used on Web, Android and iOS!

* Designed to be modified - Modify the UI/Backend so you can have custom experiences for your use cases. As long as you satisfy public APIs any piece can be swapped.

* Easy to deploy - docker-compose with LetsEncrypt support. Spin up a conference server with on command

* Performant - You can run multi person conference calls on AWS free tier instances

* A joy to develop - Pure Go means quick builds, and a code base that anyone can contribute too!

* Community owned - The only thing driving the project is the contributors and users

We also plan on adding lots more, with some of the following in our road-map already. [0] If you are interested in learning more about some of this stuff, this is a great chance! It is really rewarding seeing all the innovative things being built.

* RTMP Ingestion

* SIP Support

* Server Side Processing/OpenCV

* Record calls

We would also love to have you! If you are interested in working on this project you should join our Slack[1]

Yes definitely some inspiration taken from there. Wanted to get to the equivalent of the release the drones button.
Thank you for pointing that out! <samp> does indeed have a default font-family of monospace there.

And <code> isn't defined at all! I'm not disputing this is all internally consistent or that I used to write what I'm now learning is incorrect HTML, this completely explains what I used to know about the tags and I love it:

I didn't know or forgot <samp> was a thing for whatever reason. I know HTML5 is big and I don't know it all, HTML4 is much less so and I usually do.

I always prefer <pre> when I'm writing HTML to show intentionally-monospace blocks like code or code output because <code> is inconsistent, importantly for me it meant sometimes it didn't|doesn't work. Here I now know why: The CSS2 stylesheet doesn't define anything for <code>!

Other replies have described how it makes more literal/semantic sense to nest these things together and I agree completely; many times I am surprised at how elegant these old specifications are, if indirectly.
> Using dgit doesn't require running a "node" of any kind (aka an SSB peer)

Can you expand on this? An SSB "peer" is entirely local, so conceptually similar to a `.git` directory.

I'm struggling to understand how a decentralised system can operate without peers.

(I clicked through on the Tupelo link, but from what I can glean from the README, a Chain Tree sounds very similar to an SSB peer. Just trying to understand the distinction)
First thing I thought too. I like and trust it as I doubt Mint would play with danger. They're solid.
