I appreciate the response! Sorry to only be pointing out problems by the way. Plenty of other components do seem well done. I just know that in your shoes I'd want to know where users struggle.

> Initial load

I just poked around a bit, and I think the other commenters on mobile or firefox might mostly just be noticing main.[key].js being slow. The inital load is structured as a couple of sequential requests followed by a lot of js (device dependent, 0.5s - 7s+) and then a lot more requests fired off mostly in parallel.

> Refresh bandwidth, caching

Your heaviest assets are set with max-age=0, and the server often responds to an if-none-match header by regurgitating those assets. Refreshing after doing stuff in the app (or just waiting) for 3min reliably generates nearly as much latency as a cold load.

If you expect most mobile users to prefer your mobile app it might not matter, but a workflow that looks like doing something on your site, navigating to another site or app for a few minutes, and then coming back can often trigger a mobile browser to refresh the page -- especially on lower end devices where the cold load is most expensive.

> Native apps

Awesome!

> Shortcut hijacking

Mostly a misunderstanding on my part. It looks like the following things are happening:

(1) Keyboard hooks apply across the whole app, even in screens where they do nothing (like using CTRL+SHIFT+I in the settings) or when the elements they would apply to don't exist yet (like navigating between cards).

(2) I falsely assumed the cheatsheet of commands was comprehensive.

(3) Nearly every navigation keystroke (space, shift+space, arrows, ...) is actually used by something in the app, mostly stuff that doesn't work till you have cards and friends and whatnot.

The net effect for me was that it looked like all my favorite shortcuts were being swallowed and not doing anything useful in return. I don't have much useful advice here, but easy discoverability of all commands might be nice.

> Privacy

That makes sense. Reflecting back on exactly why I found that off-putting in the first place, I don't necessarily think the problem is with the search feature (some people probably disagree), but with the fact that it wasn't clear the information would be public when I was first asked for it. That might lend itself to a simpler solution.
Forget cooling for a minute. Cooling dissipates energy but you need to collect the energy first and worry about powering the server. It’s going to be a solar-plus-battery system, which is heavy and expensive, with substantial launch costs.
Some systems do have two parity bits but obviously there’s efficiency loss there.
The note on spiders on drugs reminds me of the Canadian documentary bit: https://youtu.be/p2HipedgM3I
I read "90% of unused allowance carries over to the next day" as unused allowance carries over exactly 1 day. That is, it's the allowance that carries over, not the carry over.

If allowance is fungible like you say, then sure, you're right. My experience of accountants and lawyers is that they don't treat these things as fungible, and are more likely to do something like:

Day 1:
allowance 200 emails
carried over 0
consumed 0

Day 2:
allowance 200
carried over 180
consumed 0

Day 3:
allowance 200
carried over 180 // 90% of 200 not 380
consumed 50 // consumption taken from allowance first

Day 4:
allowance 200
carried over 135 // 90% of 150 not 200 or 330
consumed 0

and so on.

Maybe it's treated as fungible, but IMO the above is how lawyers and accountants would treat it.
Of course that's not true. I mean, the Netherlands and Switzerland have private insurance for healthcare. Are you saying they have no incentive to maintain their health?!?
Genuine question here, why go through all the trouble of manually removing the networking code?

Wouldn't it be much easier to replace the import/include/whatever of the low level networking bindings with a stub library where all functions just immediately return with a networking error, as if the computer was off line?

That would make it all but trivial to keep up with upstream code changes, and keep the disconnected version up to date.
This was not the case in 2015/14. These stack overflow answers easily confirm that you needed to open it at least once, and that there have been related bugs in that time: https://apple.stackexchange.com/questions/175069/how-to-acce...

>The Ena.Computer is designed using 550 double triode 6N3P electron-tubes, all configured as identical 5 input NOR gates. Registers and counters are built from these single NOR gates and combined into master/slave D type flip flops, an 8 bit ALU, and all latches and buffers.

In my computer science program, we had an old school prof who insisted we build a virtual CPU using only fundamental components. No VHDL for us! We wanted a JK flip flop? Here are the logic gates. Wire them up baby. The only thing that came for free were the logic gates, a clock, and probes. Some students complained about it; and I get it, it was a very old-school way of doing things. But I can say that I intimately understood my 5-staged pipeline CPU, because I designed it from the ground up, and spent hours wiring every component. I also had plenty of time cursing myself for some stupid design decisions I made along the way. The only thing that might have made it better if we were tasked with actually building it out in actual hardware. I'm a fan of those homebrew cpu's out there. Maybe not practical from computing perspective any more, but sooo cool.

I get the impression that Apple since Jobs' return has actively gone out of its way to try not to have pundits and the general public make the pretty obvious comparisons to B & O or Bose, because they rightly see it as not a flattering comparison for Apple.

If it cost money to produce or is worth keeping for sanity sale ECC. It's just common best practice. Failing that yes you have to burn CPU verify.

Temperatures on the surface of Venus are around 500 deg C, the pressure is around 90 Gs and the atmosphere is actively corrosive with superheated sulphur dioxide etc. While you may indeed be right about terraforming, settling on Mars seems like a cakewalk by comparison.

Occam's Razor would be: They seriously just want telemetry to understand where to focus on. What is being used. What is crashing.

(While I don't think telemtry-driven developement is good: with an audio workflow there are some filters one uses always by default, but the relevant features are the filter one rarely uses, but which make a difference when being used)
I believe it's a use case for RedShift if anything, not DynamoDB.

RedShift is column oriented, if there is some types for numbers/timeseries, that should be able to do the job. It might still be cost prohibitive though.

I personally find the 1M writes to be misleading. It's typically 1000 sensors generating 1000 metrics (a large key=value file). It should be ingested in batch. I guess it's not impressive enough if you call it 1000 requests per second.
Yet, the core is even hotter. So we're mostly talking about the relatively thin crust layer on top. Core and mantle has practically unlimited energy supply as well. The planet is basically alot larger, and contains lots more energy than we normally account for.
What if the aliens had access to culture? They could then maybe raise the clones as cultural humans that could be somewhat close to us.
I think that's the part people need to hear - we're moving from semi-stable to a more chaotic climate.

The extremes are moving, and it doesn't take many shifts to destroy everything. E.g. dry + fire, or ice + time, or storms + floods, or humidity + time
Yes, but urgent care would not have been able to address the issue described here. In general urgent care is only qualified to address simple, common illnesses and conditions.
Why? When you do Raman spectroscopy, in any given session you're likely to see 1 going through a 1 cm^2 sample. Students are taught that if you get a super sharp increasing looking peak, first rerun it because you probably just saw a cosmic ray.

Given the rate required for this its not a reasonable assumption. It's like saying Amazon sees sha256 collisions between S3 buckets. Just doesn't happen in practice.
I've played around a bit with DHT indexing recently and a very simple python program using libtorrent to send sample_infohashes (BEP51) and download metadata (to get names/files) was enough to get me 1-2 .torrent files per second without any special effort or aggressive settings. The bottleneck (by 10x) has been the embarrassingly parallel info hash to .torrent step, so speeding things up shouldn't be very hard.

After running it sporadically for a few months I ended up with 1.4M torrent names and 30M info hashes, but I never put any work into estimating the size of the DHT, so I don't know what sort of coverage that represents.

Checksumming filesystems and file transfer protocols cover many cases. SCP, rsync, btrfs, and zfs all fix this problem.

As for guaranteeing the computed data is correct: I know space systems often have two redundant computers that calculate everything and compare results. It's crazy expensive and power demanding, but it all but solves the problem.
Dont Ignore SEO
In my experience it's better to run redundancy on a higher abstraction level.

I.e. (simplified) you do the computation twice on different systems then interchange hashes of the result and if they match you continue.
Not entirely sure what people need to hear. We need better models and problem definitions.
Comments like this one are depressing. Many in government are passionate about lowering the price of healthcare. A number of politicians support some pretty dramatic proposals for solving the problem. The issue right now (to put things politely) is that the voting population does not agree on the solution, and our political system makes it very difficult to get anything done unless the voters are willing to express their preferences by voting for politicians that support one approach, giving them a super-majority and control of multiple branches. Last time that happened was 2008.

TL;DR: If you actually care about this issue, you shouldn’t be offering vague platitudes blaming it on “government”. You should advocate for your preferred solution and name the politicians/party you think we should vote for to get it passed. I know this is political and not loved on HN, but this is how the system works.
I would like to say I have a job for you but I am afraid that this kind of decisions is way above my pay grade.

Are “cosmic rays” actually the only or primary way bits get flipped? Or is it just a stand-in for “all the ways non-ECC RAM can spontaneously have an erroneous bit or two”?

I live in fairly typical wealthy US suburb, my kid is 7 (1st grade) and goes to school on her own - school is around 0.5 miles away. I have to pick her up from school (parents are required until 3rd grade to check out kid) but often just leave her on playground to play with other kids (unless she has activities that day - which frankly she has more and more of - chess, math, soccer, gymnastics and ballet right now). She walks back home whenever she is done playing. I see kids 10-12 years old biking everywhere and hanging out in Starbucks/restaurants on their own. There are busy roads but you can go around them on secondary roads with low/non existent traffic.

While not majority, there are quite a few people who give the same freedom to kids as us. So far we had zero problems but i am thinking about getting smart watch with GPS for piece of mind.
This is mostly an U.S.A. point of view.
As an European, and now Canadian, of all the countries I lived in, the U.S.A. was the only one who did not think that the health, education, and opportunities of their citizens was good for the nation and more importantly the state.
I think that in this context the meaning of the term trust is different.

Any code executing in privileged mode can bypass security, and is therefore inherently part of a system's trusted computing base (TCB). (Linux is a monolithic kernel running in ring 0)

Most companies are not Linux contributors, they are trusting the kernel developers to write bug free, secure code.

Minimizing the TCB and opting for an auditable open source TCB are really useful concepts in security.

But the cause of these breaches is much more trivial than what you are worrying about: these companies are basically installing whichever piece of software can decrease their costs without thinking about what they’re doing.
A high portion of health insurance claims are automatically adjudicated, but it’s far more complex than you would guess.

Governments do have incentives to keep the population healthy, as seen by free covid vaccinations by a GOP administration. The dead don’t pay taxes.

The important bit is a lot of healthcare makes minimal difference. People have a huge bias around doing something even if it doesn’t help. Governments on the other hand care a lot more about the cost/benefit from healthcare thus vaccination is considered an obvious win but Medicare puts limits on physical therapy etc.
Agreed. The firmware has nothing to do in the schema.

And to make things worse the most used timeseries database, Prometheus, is missing.

10M is not particularly high. If your company run prometheus/nodeexporter monitoring 1000 servers, you should be in that order of magnitude (expect 1000 to 10000 metrics per machine).
Yeah, from the article the baseline for the big stuff is 5 trillion

And this, my ladies and gentlemen, is why healthcare shouldn’t be “insured” but a fundamental human right catered for by an essential public utility (universal healthcare).
So I wrote this back in the day when I was leading a small startup, I think the advice is still valid and can help others. Cheers! :)
There's no reason to think it would have produced better results than a free market economy.
I’ll say Uber rejected this due to highly unlikely user interaction required .
America’s policy in Afghanistan is absolutely horrifying. Invading them, then occupying and setting up a government, then abandoning it is a foolish waste of trillions of dollars. It is incredibly inhumane to all of the Afghanis who supported us and to all of the regular citizenry there. Remember all of those schools for girls and things like that? Those poor girls are now in for a short and tortured life. America should have done what Rome did and annexed Afghanistan and set it up as another state in our union. A permanent commitment would have paid off in the long run, but now we just have created a failed state that will fall into civil war.
I had a fictional concept of gas mining in the atmosphere of Venus (like Bespin's Cloud City) but I couldn't think of a way to mitigate corrosion of the materials you'd use to build it by the sulphur dioxide...

(On Venus at 50 miles up, the atmospheric pressure is approximately the same as Earth, whereas on the surface it's the equivalent pressure of Earth's Mariana trench.)
The design of the Venera landers is fascinating, wikipedia has some good pictures https://en.wikipedia.org/wiki/Venera

The probes were optimized for surface operations with an unusual looking design that included a spherical compartment to protect the electronics from atmospheric pressure and heat for as long as possible. Beneath this was a shock absorbing "crush ring" for landing. Above the pressure sphere was a cylindrical antenna structure and a wide dish shaped structure that resembled an antenna but was actually an aerobrake. They were designed to operate on the surface for a minimum of 30 minutes. Instruments varied on different missions, but included cameras and atmospheric and soil analysis equipment. All four landers had problems with some or all of their camera lens caps not releasing.
Of all the possible outcomes of Copilot, someone suing Github and demanding they make their source code available would be by far the most hilarious timeline of the whole Copilot debacle.
Another issue I think is that the average hides a lot. Both (1, 2, 8, 9) and (4, 5, 5, 6) have the same average.

Now extend that to 365 days, and there's a lot of room for wild events leading to "just" a 1 degree increase in average temperature.
> I want to deny network connections by default and specifically enable who can speak to the outside world.

I also want to filter the network data. I want my firewall to inspect what the software is sending over the network and delete, randomize or nullify all data that isn't strictly necessary for it to perform the desired function. Like uBlock Origin but for the network stack.

This would enable normal operation of the software while also at least partially subverting the "legitimate business interests" of these corporations.
My favourite shell scripting function definition technique: idempotent functions by redefining the function as a noop inside its body:

foo() {
foo() { true; }
echo "This bit will only be executed on the first foo call"
}

(The `true;` body is needed by some shells, e.g. bash, and not others, e.g. zsh.)

> You’ll rarely review single commits anyway.

This is just because Github and its imitators are bad software - which isn't really git's fault. git and Linux practice only commit-level review.

> Many of my colleagues view using Git not as part of their core work but an inconvenient chore.

Many people don't care about version history, and ignorance of how git works (or adherence to superstitious rulesets) on the part of the people who do care provides them cover for trashing the history.

Many people don't care about code quality or maintainability. However, these people are more likely to be prevented from trashing the codebase itself than the ones who don't care about history are from trashing the history.

Commit history is just as subject to review as the contents of diffs.
Some patients are too complex, in terms of pre-existing health conditions, to go to urgent care.

I am American (living abroad) and I have 2 rare immune-mediated neurological diseases affecting my peripheral nervous system, plus type 1 diabetes (autoimmune and insulin-dependent). My doctors in America told me to never go to urgent care for my health issues in the US.

Even ear infections can be complex. One time I had blisters on my eardrums (bullous myringitis) which is considered to be excruciatingly painful. After 3 out of 5 nights being sleepless due to pain, I wish I had went to the ER instead of waiting to finally see an ENT--after going to an urgent care (where I received improper treatment).

ProTip: With respect to cleaning your ears, don't use Q-Tips, ever. Get a digital otoscope (technically an ear endoscope) instead. It is the best piece of technology that I purchased on Amazon, that I thought would be junk. It allows me to thoroughly clean and inspect my ears daily.
So better documentation of exactly how badly we are screwed? The ship is sinking. We can measure water inflow to better predict how long we have, or we can start plugging the holes asap and pray we can do so in time.
The deal to be acquired by Muse Group was announced 30 April, and "Muse Group was formed just a few days prior to the Audacity announcement, on 26 April"

The latest release "Audacity-3.0.2" tag on github is 14th April, as is the date that the Windows 3.0.2 installer was signed. So the current latest release predates the announcement and formation of Muse Group.

The privacy notice was updated 2nd July. We don't know if that's when the new clause was added, however issue #1213 on github suggests that it was.

But I've not looked at the code, so don't know what telemetry was already in place before the project was acquired. Anyone?
I just spun up a very simple 3 node EKS cluster using eksctl on us-east-1 and it took 19 minutes. Still seems quite slow to me, I'm not sure how you got 11 minutes over a sample size of 50+ clusters, maybe it's dependent on region or what worker node types you used?

You multiply the probability of two random events to get the probability they will happen at the same time. If the expected value of a bit flip is 10^-18 then two would be 10^-36 and three would he 10^-54.

At some point it becomes a philosophical question of how much can the tails of the distribution be tolerated. We've never seen a quantum fluctuation make a whale appear in the sky.
