They aren't arbitrary. They're a compromise/trade-off between several conflicting goods (e.g. aligning the clock to solar time and using time for regional coordination). If you change their number/size on goal will get worse and the other better.

I have on average about 3-10 Zoom calls daily and I definitely see the value for this. Right now, I'm literally bouncing between Outlook, opening calendar invite, pressing the link, having Safari launch a new tab, press Allow, and then Zoom opens up.

Curious to know what the longer term plan is. How will this grow past being a calendar widget?

That "once again, Canada is not the problem" line in the viral post is missing the point so, so badly.

Like, yeah, lots of industrial waste comes from developing countries where the major production centers are, mostly in Asia. But the people sharing that image should ask themselves where those products go after they're made. A huge amount of that production is for the richer Western countries, and that does make it your responsibility if you live there.

This is how industrialized countries lower their CO2 output as well: just outsource it other countries. Under the Paris Agreement, countries are only held responsible for emissions that occur within its borders. It's just another way for the greatest consumers to be able to shrug and say "not our fault".
Man, that is it exactly, they threw everything and the kitchen sink into it AND made it unnecessarily difficult to update systems / be compatible with IPv4.

They should have had IPv6 with a header or config for IPv4 gateway(s) configured at the IPv6 boundary of your current network (could even be local / on device if needed). Want to talk to IPv6 - you go native. Want to talk to IPv4, connect using known prefix to IPv4 boundary gateway and it NATs you out.

The implementation / firewall changes needed for this are crazy, the config stuff also crazy, the number of layers of encryption I'm hitting (I'm IPv6 on a VPN using wireguard tunnels and browsing in SSL on my remote machine) seems nuts.
>> but even the B-2 can be spotted pretty easily via the Mk 1 eyeball.

It has a visual cloaking device too. It isn't terribly complicated. The bottom of the aircraft is a particular color. If you fly at an altitude that the sky above is the same color as the bottom of your plane, people on the ground cannot see you. So a tiny camera pointed up can be used to calibrate the altitude to best hide.

Also see counterillumination, a trick used by many sea creatures to hide from things below them. I doubt the B2 uses this but the military has studied it as an option in the past.

Yes, at home I have choice of computers and usually I take a desktop.
Just add a good webcam and headset (or microphone) and it's the perfect work-from-home system. Much faster than any laptop, better ergonomics and cheaper too. And you can even disconnect mic and webcam physically (a.k.a. unplug from USB) as a security feature!

In a nutshell, I moved away from Electron (which was a quick prototype anyway) and have built a local service with uWebSockets.js and a systray icon.

Unfortunately for Fraidycat, I had an opportunity to collaborate with someone that I'd really been wanting to work with - so we've spent the last four months working on a blogging tool that's supposed to pair well with Fraidycat.

But I will be back to Fraidycat in the next few months to finish. I appreciate your curiosity very much!
Have you tried actually contacting any school boards to ask why you're being blocked?
As someone that actually uses LTSpice I’ve never considered speed to be an issue. The main draws for it are

1. It’s free unlike Altium addons or orcad p-spice

2. Graphical, I’m happy to code things but code literacy varies widely among EEs. Much easier to share results when it looks like a schematic

3. Good enough component library. The time spent finding and inputting component parameters are gonna be way bigger than any savings on the actual computation

I mostly work on small embedded systems boards and use simulation to probe behavior of analog sub systems I’m concerned about, rather than simulating the whole board. Maybe more complex designs get more like CFD models where computation time is measured in hours or days. Would love to see someone use this as a backend for an alternative to the major spice programs, LTSpice UI isn’t exactly pleasant, and is unusable on Mac so it wouldn’t take a whole lot to get me to switch.

Exactly. The built-in Calendar app is adequate for most tasks (definitely adequate for just delivering notifications).

Besides, there are quite a few decent free calendar widgets out there already.

Set your calendar to notify you 15 min before the meeting starts. It's a trivial problem to solve without paying $120/yr.

Sorry, but you're marketing your app as "luxury" without delivering any luxury.

What are you basing this on? Current research does not agree with this and, anecdotally, my daily experience also doesn't agree with this. People can buy things on Amazon easily because Amazon has optimized for that. Anything outside of that (account management, returns, etc.) are still not intuitive for most people.

Scientific computing has always been around, but as you allude, a bit in the background. It used to be matlab/mathematica on your desktop or a supercomputer that very few could get access to and program. With cloud computing, GPUs, ability to get terabytes of RAM on a single compute node, and all the exciting developments in CPUs despite skirting the edge of Moore's Law - a lot of opportunities are showing up.

You can now simulate science in ways like never before. Today, the median scientist can easily rent a cluster of hundreds of nodes for a few hundred dollars an hour. It is increasingly the case that you can actually simulate entire products in silico before you do anything in the lab. SciML is a large part of that story because we are able to use ML to approximate science and speed it up even more.

I like to think about it as follows - 10x faster CPUs, 100x from GPUs when possible, 100x from ML when possible, 100x through easier access to parallel computing on cloud. So your best case speedup compared to a decade ago is easily 10^7x. Because of this huge space for improvement, we can easily find 1000x improvements in so many cases.

And this is what we as software engineers can do to change the world - by simulating science, building new batteries, designing new drugs, solving power infrastructure, getting climate right and its impact on our cities, food production, and so on and so forth.

Bret Victor captures this really well in his essay: http://worrydream.com/ClimateChange/ and at Julia Computing, we are doing a lot of what it outlines, and really grateful that ARPA-e and DARPA are funding all this hard science and improvements to Julia and its ecosystem.
This is about funding for future work, not payment for achieved bonuses, it seems.
What, from a black box perspective (i.e. performance, reliability, cost/compute, maintenance-cost/compute) distinguishes a modern mainframe from a modern onsite private compute cluster?

Let's say both are running the same OS and application using VMs, and neither is doit specialized types of compute (i.e GPU stuff), just processing gobs of transactions.

Obviously there are big internal architectural differences, but ultimately these must manifest in some quantitative and qualitative differences and tradeoffs from a black box perspective.

Please discuss.

This isn't true at all. Many many many of my non-technical family members would not have any clue why emoji domain names and emoji email addresses could not be used. They love emoji (like most people) and want to use them everywhere. And if someone offered them an emoji email address, they'd easily pay for it and expect it to work like gmail/hotmail/yahoo

They would not understand the following terms: unicode, punycode, domain name, mailserver, mail forwarding, tld. They would even probably reply to the wrong email (the website shows that the emoji email forwards mail to a normal email which sends the mail to you, so you should not click "Reply" on any email forwarded from this service to you).

I do think there can be a beauty in more esoteric words and longer sentences that cause them to feel more like poetry. This can, perhaps counterintuitively, make sentences feel more conversational as opposed to less.

I can edit the above to;

> I do think specific words and long sentences have their place. They can be used to alter the flow of a sentence and make it feel more conversational instead of less.

But it's not the way I talk. I enjoy the way you can alter the cadence of sentence to impact the reader. For example: the phrase, "perhaps counterintuitively," is like a rolling hill the reader spends extra energy to climb but then engages them with the writer, "I'm interested, I like hearing about counterintuitive things" -- it's almost an invitation. You've set an expectation that something counterintuitive is ahead, so what's next?

Generally, I could use more of Paul's advice in my own writing. And that's the fun of writing, learning to write is a very organic process. But I'm sure everyone can find their own style somewhere in between simple, poetic, natural, or whatever makes you feel the happiest about your work.
That was freaking awesome.

Basically it's a long and technical shaggy dog story. He started with an insane premise (emoji domain name ?!), added enough detail (The night of 150 emojis) to strain even a willing suspension of disbelief yet still without breaking it, and then ended with an anti-climactical (because it is a shaggy dog story even if true) $1440/year ARR.

Bravo.
We are on the phones since the start of the week with no avail. It sounds like there are some shadowy IT providers that are hard to reach that are doing all the blocking and locking down of machines. Someone else on this thread mentioned one such provider.

The lobbying effort in the mid 2000s for a "nuclear renaissance" was absolutely a tour de force. It passed laws in US states that put all construction economic risk (the biggest risk of nuclear) onto rate payers rather than the utilities that start nuclear construction projects. These sorts of shady laws sneak through state legislatures all the time, but these ones in particular were the only reason that utilities in Georgia and South Carolina embarked on construction projects. Of course, these have been massive economic and management failures, as nuclear too often is. All the US/UK efforts are echoes from that lobbying push.

And in the mid 2000s, nuclear seemed to be a much better idea. Solar and wind were more expensive, not far less expensive, than estimated nuclear costs. It seemed like nuclear was going to be an absolutely essential part of a carbon neutral or negative society.

Fifteen years later, we have had an energy technology revolution, and we are still in the middle of it. Personally, I don't see a future for nuclear, and for that matter I see only niche applications for thermally generated electricity. Other technology will undercut the steam turbine driven electricity that has been the basis of grids for a century. We might have some chemical storage in hydrogen, methanol, methane, or longer carbon chains that comes from atmospherically extracted CO2 for use in extreme scenarios, but it also seems likely that long-duration battery storage (e.g. vanadium flow batteries) will get cheap enough to replace even that.
Impossible. That has 84 characters. Also, since it doesn’t seem possible for a language to receive grant money, I don’t think there is much chance for a dangerous level of confusion.

I set up a personal mailserver a few years back, and have hit a lot of painpoints. The main ones were software complexity (setup) and dealing with blacklists (ongoing).

Setup for a normal mailserver requires Postfix (SMTP send/recieve), Dovecot (IMAP mailbox management), SpamAssassin, a webmail frontend (Roundcube), something for user management (MySQL + PHPMyAdmin for me) and a generous amount of glue. Things like DNS records, config files, spam rules and classifiers, etc).

Blacklists are far more annoying, especially w.r.t. GMail. I use a DigitalOcean node, and some of their IP ranges are blacklisted due to past spamminess. Depending on the provider, there may or may not be a bounce email, and may or may not be a whitelisting process. I've even seen mixed results within GMail. I can send from my custom domain to my GMail without trouble, but emails to a friend using a custom domain on GMail are dropped silently. (That's the worst of self-hosting, I think. Silently dropped messages are way harder to detect than a mailer-daemon block notification.)

Long story short, it's a mess :)

On the flipside, similar commercial plans (3 domains, 20GB shared storage) run $30/mo or so, which is way more than I'm willing to spend on a vanity email. Sounds like a similar story for mailing lists.

I'd give self-hosting a shot and see how it goes. Since mailing lists are opt-in, users will know if they aren't receiving what they signed up for, and are likely to reach out for support help. That's different than conventional email, where a silent drop and no reply are hard to tell apart for the recipient.

Hope that wasn't too much info/text, and good luck!
Many people have the notification center on Do Not Disturb indefinitely. It's noisy and unactionable for a a lot of people, including myself.

We want to integrate deeply into SaaS platforms to provide one-click access to features within those platforms. For example, viewing and resolving comments on a Google Doc. This just isn't possible through Mac's notification center.

Since this is based on ML, I would have trouble trusting the results. Can you verify the results with standard mathematical methods? E.g. solve a linear system using AI, then compute the residue and meaningfully interpret it? Would it be possible to apply ML techniques iteratively, and let the error approach zero?

I have no idea what you're talking about. I'm using multiple Google Calendar accounts just fine with the built-in Calendar app.

So basically, a calendar widget and a notification center (which is already a part of the OS)?
I am always baffled by this take. I run k8s because it's by far the easiest way to do what I want (deploy a handful of services to a handful of servers), not because it's cool or massively powerful.

In the past few years, k8s simply got easy to get started with and it feels like no one noticed.
The 1000x goal here specially refers to algorithmic accelerations. Depending on your baseline simulator, there may also be improvements because Julia's simulation capabilities are extremely fast, but those gains are multiplicative, since we're using our own simulator as a baseline for measuring the algorithmic improvements. Just to be clear though the 1000x is a goal. We've demonstrated the same techniques at about 100x algorithmic improvement (for close to 1000x overall), but haven't quite gotten to that point yet in this domain. It is still a research project at this point. We are quite actively exploring what to do with just the simulator components though, because we think there's a good opportunity to replace some legacy tooling in this space even before factoring in the algorithmic improvements.

Calendar.app works fine with GCal though (notifications, accepting/cancelling invites, etc.). I still go through the Web UI to create invites and what not (because I want my automatic zoom meeting and decent scheduling tools), but that happens seldomly.
When your founder and CEO makes growth the only thing that matters, everything else is not important. If selling people lies makes more money, sell more lies, etc. If Facebook charged people $1 a month per account, and deleted all the ads, the data selling, the lie promotions, etc, 95% of their company could be laid off. They would also make less money for sure, and that's something Zuckerberg could never support.
It's because it is a common spam action to use <site>@<free_email> when blasting out stuff. It's also common to try and use <something>@<site> in either/or the to/reply-to fields for spambots.

> So "thousands of years" is a popular misunderstanding, in my view.

"Thousands of years" comes from the half life of Plutonium-239, which is 24,000 years.

Pu-239 isn't unusually dangerous for an isotope. It's chemically toxic and somewhat radioactive but so is tons of stuff. The biggest problem with it is that you can make nuclear weapons from it.

Most commercial reactors make both Pu-239 and Pu-240. They're infeasible to separate (harder than separating U-235 from natural uranium) and enough Pu-240 makes the plutonium unsuitable for weapons.

But Pu-240 has a shorter half life than Pu-239. So if you take the plutonium out of a legacy reactor and bury it in the ground for a long time, it turns into weapons-grade plutonium. Burying it in the ground is very stupid because then you have to guard it for tens of thousands of years to keep anyone from going in and taking it to make nuclear weapons from.

But that ship has sailed. We have a half century of the stuff already. Half again as much or not makes no difference, we need a solution for what do with what we already have regardless of whether we make any more.

The solution is that newer reactors can use plutonium as fuel, which permanently eliminates it. So far from nuclear waste being a reason not to build newer reactors, it's the reason we should, so we can get rid of what we already have before it becomes suitable for weapons.

They -can- emit higher frequencies with better fidelity (and DR), however that's a product of mastering the CD, not something that need occur in the CD by its very nature. So the way you're stating it is incorrect. A CD can replicate anything a cassette/vinyl can do (that is perceptible by human hearing). Now whether industry respects that or not is up to the company/band/whatever making the CD and what they choose to emphasize.

Teaching Android Development with Kotlin: The Stanford Approach
Many people keep saying something to the effect of, "There is a right time to scale a system and we need to focus on that." This is true. There is a right time to scale up. In my experience, you rarely know when that might be except in hindsight.

I worked at a startup once and we built the product in a way that it should have been able to scale up pretty well. Then one of the co-founders went on a national news channel and started talking about our company. Our servers got absolutely slammed with traffic. We did the best we could but it didn't go well.

Now, we should have known to expect increased traffic from an event like that, and, in fact, we did. We simply didn't know just how much traffic we were going to get, and, honestly, couldn't have known that. We had only had a tiny fraction of that traffic until that event. That was the best basis for comparison we had at that point in time.

We updated and upgraded some things after that and the next time he went on that news channel, things were a lot better.

Knowing when to scale up is a hard problem. You have hints, sure, but there's never a data point that says, "Ok, you have until July to migrate this system from a single VPS to a full Kubernetes build-out."
