I understand why it costs this much. I don't understand why we think it is worth doing. Rather than fabricate a flying White House, why not deputize the vice president to carry out presidential duties while the president is in the air? There is a well-defined presidential line of succession that exists expressly to ensure continuity of government in case the president is incapacitated. Why reserve its use for emergencies? We can use it routinely.

Database basics: binary expressions and WHERE filtering
Interesting, didn't realize it imposed a lot of client side changes, I'm curious to hear your experience on that? Was it the change in MySQL compatibility that makes it an upfront cost?

With Vitess I believe most get started with just deploying VTGate and just proxying their existing queries to their existing MySQL server, then once that is working nicely, start to range shard and expand the cluster sitting behind VTGate.
Isn't this more like a sandbox that lets you play in the sandbox with a CLI? I don’t think it actually gives you shell access to your iOS device, just a shell interface to its own program (and the other commands it supports).
QFT says it's all fields because it is. Particles simply cannot explain the conjunction of quantum mechanics with special relativity.
You're forgetting time of infection.

You only need to download tokens for people who tested positive in the recent past (14 days - assuming you're not infected, any contact before that couldn't have infected you.)

While that's likely still a lot of data in areas with large daily case counts, at least it won't keep growing indefinitely.

BTW it's one token per day per person, to improve privacy. When someone tests positive, their tokens for the last 14 days are published.
Bespoke professional services work costs bespoke professional service work rates, film at 11, but one factor not already discussed here:

A lot of contracting arrangements like this will ratably assign overhead to particular change orders or line items in ways which will cause the apparent cost of the line item to be higher than one might think necessary. This is, mostly, to avoid there being a "$250k for the manual; $5 billion for Miscellaneous Expenses" sort of bill.

(The question of whether government contracting is optimal is a long and involved one outside the scope of this comment.)
There is a team at Debian forming to package machine/deep learning software:

There is reportedly a lot of specialized gear added so it's not surprising there's extensive documentation. What I find really surprising is the new aircraft cuts aerial refueling capability: https://www.thedrive.com/the-war-zone/14199/the-next-air-for...
After working in Aero, I'm still amazed airplanes fly at all.

Every single line of that document would have been double checked multiple times, and literally have 3x more documentation tracking why that piece of top level documentation exists and tracking any changes to it.
It's a problem in the sense that you still don't want to infect more people than you have to, there's still 20% hospitalization rate. Though I agree it's easier to maintain quarantine in countries with lower density and larger houses / suburbs. But one additional problem identified is adherence, especially without sufficient incentive (i.e. economic), hence location tracking or forced out of home quarantines. People become unreliable at scale.
It seems unlikely that anyone will deploy a version of DP-3T that differs significantly from the approach built into Android and iOS, due to the need for apps to obtain special permissions to run in the background. So the alternative variants that go under that brand are probably a dead letter.
Right, advertising is a form of disseminating information, but the issue is that there are limited resources to process all this information in the world.
What ads do is forcibly take my attention and direct my resources towards processing their content without my permission.
Sure, I can look away but I need to exert effort (even if it is the slightest bit).
Processing what they want to tell me makes me more informed about their product (as opposed to their competitors) which, if their ad wasn't terrible, will make me less uncertain about it.
This easily makes a number of people more likely to buy it since it will feel familiar, thus making this company better off even if their competitor had a better, but at first more unfamiliar product.

Santa Barbara is a terrible place to consider for buying/building a house. Sky high property taxes and inflated property values are begging the local economy to dry out due to rental prices (The Bay is cheaper if you compare similar apartments with similar interior/exterior). The city can't expand because of geology, and it refuses to build up to preserve the "historical view of the Riviera". Sure it's a pretty city, but it won't mean much if it's dead.
I had no idea this worked. It’s a little odd to have to give my SSH client location access, but I just tested this and it totally works.

I recommend Serious Cryptography by Jean-Philippe Aumasson. After reading it, you will gain enough understanding to compose cryptographic primitives and build your own secure system based on well-known best practices, as long as you don't deviate too much from the golden paths. Although with that, you still won't know how to design or implement these primitives yourself. It's like having a nice toolkit of screwdrivers, hammers, spanners etc to build your thing, but you can't build those tools themselves.

Yes, a lot of extra junk is needed to make them actually work, but the extra junk goes a long way toward obscuring what you actually need to know.

Ultimately, though, you are right that you have to understand it all, once, even if you can't remember it all a month later. The explanations I find online are not good at presenting just the details you need when you need them, and building up to the full picture.
If you haven't bought the VR kit, they added a full 3D editor on top of the engine from the first few releases, which allows you to create VR or non-VR games. It's absolutely incredible and was sadly overlooked. I've been hoping for them to update it with proper sharing and do a new marketing push but doubtful such a thing is coming. There are 2 VR sets available- the full kit is more impressive but the software is the same on both if you care more about the diy games than what Nintendo provides.
> Disagree with PM on a feature? If you feel strongly enough, you build it your way until they remove you from the project.

This really only works in certain companies tho. I’ve seen some of our best developers removed from our project because they refused to build features that didn’t make sense. Word just goes up to senior management, and all of the sudden you’re to blame for project delays, and eventually pushed to another project.
Are they really both significant issues? A successful cyber attack could enable a single individual to decide multiple elections. A voter id attack could enable at most, what, 10 votes per conspirator? An undetected voter id fraud changing the outcome of an election seems absurd.
Thanks for your response!

Unfortunately, I can't find my pentalobe screwdriver to open the case so I had to order one. It should be here on Tuesdsay. I can't try a different battery or check for water damage until then.

To add a little more context, this is a 13 in Early 2015 Macbook Pro (A1502.) My laptop was working until the battery died earlier today. I plugged it in and pressed the power button and I still just get black screen(I don't even hear any fans starting or anything like that.) The charging indicator is orange which makes me think that the battery is functional. When I do a SMC restart the indicator changes from orange to green for a few seconds and then turns back to orange. I have tried plugging the laptop into a monitor to rule out an issue with the screen, but still no signal on the monitor. Are there any other diagnostic tests you can recommend until I can open the laptop up?

Warren Spector said that his initial idea for the game was "what if every conspiracy theory was true?", so that's pretty intentional. So as long as you buy into that conceit, there's a lot of amazingly clever writing in the game.

My favorite conversation in the game is probably the one with the AI Morpheus: https://www.youtube.com/watch?v=1b-bijO3uEw
So because there is a mention of Norwegian heritage it's only talking about "white" immigrants? So if he had said Hispanic, etc he would be OK.

Not a convincing argument for anything.
Having never read it, the part from Google's SRE book is amusing in the best of ways - a perspective I had never considered in the way it was framed!
Odd there is no `which` command; this limits discovery.

1. You clearly didn’t reference the panel where Alice is choosing to upload data with exempting sections from it.

3. Yea, that’s great and all. The point is that you may compelled to upload your contacts - NOT your beacons. You are collecting people you met. You likely do understand some of the ways contract testing could be abused. Think about police trying to prove contact with someone they do have beacons for.

5. So why bother with passcodes, or any security at all anywhere for any new or existing feature? This is a slight evolution on “I have nothing to hide”.
There are too many factors at play right now to do anything but delay the inevitable.
I see some states saying that they want to reopen by a certain day. I appreciate my governor’s proclamation that she’s not going to give a date but the lock down will continue until she says so. That seems a lot more logical than setting a arbitrary date in the future and either disappointing people when it turns out to not be realistic or going for it anyway and creating a massive health crisis.
That's an interesting point and can help you go anywhere when starting off.

With what you've done over the past couple of decades (I assume you're the guy that has written one of the first C++ compilers and invented D), would it not have been better for you to take more classes on compiler design or other computer science/computer engineering related courses? Did jet engine analysis (I assume you're a mechE) ever help you once you found your niche?

Btw...you've seemed to accomplish far more (technically speaking) in your life than me :), so I'm genuinely asking and not trying to lecture you.

Edit: I think pretty much all knowledge I've learned has had some use, but surely the applicability would've been higher for you with more computer hardware, compiler, and algorithms related coursework?
If there was a correlation between tax rates, revenues gathered and services etc at local level I think you would have a valid point. But cities with high taxes don't seem to have any fewer problems than those with lower tax rates.. unless you see some data.
The Library of Congress launches an open source hip-hop sampling tool
Dispersion does come up; the last time I got new lenses for my glasses, one of the brochures on the table had the Abbe number [0] listed for various materials.

Generally lenses with the highest refractive indices have fairly low Abbe numbers and have a lot of dispersion; a lower dispersion lens would have to be thicker and heavier (and thus increase geometric distortion).

There are some fancy extra-low-dispersion glass formulations used in camera lenses, but apparently these are generally more fragile than typical glass and that's not suited for glasses.

I also asked my optician if there were any achromatic doublet glasses, but he told me that those would end up having to be extremely thick and heavy.

That could just be density or demographics, or fewer people with co-morbidities. I doubt it's anything to do with different approaches taken by states -- after all Wyoming didn't even have lockdowns until a week or two ago.

Lack of voter ID, combined with mail-in voting, can lead to fraudulent “ballot harvesting,” where boxes of votes are “found” at the last minute, for example. Also, many people aren’t aware that ballot harvesting is actually legal in some jurisdictions including California. [0]

I guess I am just jumping to conclusions but this article seems to describe the behavior I am seeing[1]. Here is some more context:

This is a 13 in Early 2015 Macbook Pro (A1502.) My laptop was working until the battery died earlier today(so this didn't happen immediately after a spill but I also have not been the most careful when it comes to this laptop). I plugged it in and pressed the power button and I still just get black screen(I don't even hear any fans starting or anything like that.) The charging indicator is orange which makes me think that the battery is functional. When I do a SMC restart the indicator changes from orange to green for a few seconds and then turns back to orange. I have tried plugging the laptop into a monitor to rule out an issue with the screen, but still no signal on the monitor. Are there any other diagnostic tests you can recommend until I can open the laptop up?

First of all, please don't be uncivil. Getting upset and insulting people is no way to discuss a complex issue.

As for your post; that ability gradually disappears, just as it gradually builds up when the economy is functioning properly.

Capital depreciates. A washing machine breaks down, and in the absence of a repair service provider, or an ability to pay them, the washing machine loses its utility, and a person's quality of life regresses, which has long term implications for their health.

Beyond simple equipment malfunctions, the complex interplay of incentives, trust and relationships that constitutes a productive enterprise are also disrupted and destroyed by shocks and bankrupties.

It takes years to get a productive enterprise up and running. The bankruptcies happening now will hurt the production of goods/services for years to come.

Fewer goods/services translates to a lower quality of life from less labor-saving specialization/technology, which in turn increases the strain on individuals, and thereby reduces their life expectancy.

The economic factors that affect life expectancy are far more numerous and complex than an inert piece of equipment for harvesting crops or manufacturing goods, and your analysis ignores all of that.

You should at least be able to grasp the implications of the statistical evidence, which clearly show that all things being held equal, every percentile drop in GDP is associated with a drop in life expectancy.

To discount the Economy's relevance to human life is deeply misinformed.

>>You know what can disappear, become depleted, or stretched to thin? Trained medical personal. And money flow can't replenish that resource.

Completely irrelevant to my point. I wasn't suggesting that minimizing strain on the healtcare system isn't important, or even that it isn't more important than avoiding doing some amount of harm to the general economy.

I was simply contesting your claim that the Economy is irrelevant to sustaining human life. I am criticizing how you rudely implied that even suggesting the damage to it should be weighed against the deaths caused by the SARS-CoV-2 pandemic, deserves nothing but derision and contempt.
Socrates didn't draw a crowd mostly because he was super annoying.

Pretty much every country in the world required voter-id. Even India with a population of over 900 million voters, securely counted over 600 million votes which was the largest turnout ever few months ago.
Two times zero is still zero.

We need to be able to test every single person in the country, and not just once. Not just once per month. Maybe not just once per week. Maybe not even just once per day.

The tests are not reliable. We need to be able to test every single person in the country enough times that we can be very, very sure of the results and not just pin everything on a single negative or positive result. And we need to be able to do that frequently.
On Twitter, there is a single type of content (a tweet). With blogs, there are two types of content (posts and comments). While it seems like a small difference, it changes behavior and appeal. When Alice comments on Bob's blog post, Alice is on Bob's "territory". Her comment is not an equal blog post in response. It will primarily be seen by Bob's audience, and most of her own readers will be unaware of it.

On Twitter, there is discoverability. As you browse, you frequently jump across profiles, and are continuously recommended users to follow.

On Twitter, there is brevity. In general, blogs are not designed for hundreds of short posts.

On Twitter, you do not have to pay for hosting, nor do you have to manage anything.

So there are a mix of technical, social, and network effects. Until these problems are overcome with a single solution, Twitter will retain its stranglehold on content.

Personally, I wish Twitter would just remove post length restrictions and make it a proper micro-to-macro blogging service. (To be clear: I'm not a fan of a Twitter monoculture, I hate their UI, they make getting data difficult, their site is painfully slow, and they are often user-hostile. But it's been years and no micro-to-macro blogging service has overtaken them, and at this point it'd be better to have something dastardly that works, than something dastardly that doesn't.)

> "There is plenty of work, why focus so much about the big tech companies?"

Big tech companies tend to have interesting work. Why would anybody jump through the hoops to go to a top university to get an ordinary coding job?
Isn't TOPS available to all that graduate highschool with 4 years of math, English, and 2 years of foreign language (i.e. everyone)? It seems pretty egalatarian to me. Granted, the rich can afford to study and hire tutors, so getting a 32 on the ACT is far easier for them, than someone that is poor. That's more of a problem with our failing public schools though.
I think the problem with a lot of these ideas is that the value of fork() is only marginally higher than the value of starting a fresh process with arguments on a remote machine. The complexity of moving a full process to another machine is 10 times higher than just starting a new process on the remote machine with all the binaries present already.

Quite frankly, vfork only exists and gets used because it's so damned cheap to copy the pagetable entries and use copy-on-write, to save RAM. Take away the cheapness by copying the whole address space over a network, adding slowness, and nobody will be interested any more.

And both techniques are inferior to having a standing service on the remote machine that can accept an RPC and begin doing useful work in under 10 microseconds.

RPC is how we launch mapshards at Google with a worker process that is a long-running server and it just receives a job spec over the network and can execute right away against the job spec.
I've said this before, so apologies for repeating myself:

Luck is making the better decision in a timely manner based on incomplete knowledge where each option appears equally valid. However, people generally are poor at calculating probability combined with risk/reward and simply make bad decisions. And sometimes, all choices lead to bad outcomes.

https://news.ycombinator.com/item?id=19308323

To expand on this; if you are a healthy, intelligent adult I don't accept the idea that sometimes you don't have a choice, that somehow it is all out of your hands. That thinking leads to victimhood which is really an avoidance of taking responsibility for your decisions.

Yes, sometimes you get the bear, sometimes the bear gets you - but you chose to take on the bear, whether directly or due to some previous decision (that didn't involve a bear at all).

Enjoyed watching "The Gentleman" the other night and a fan of films like Lock Stock, Two Smoking Barrels and the idea of events snowballing from the choices people make (and then the interaction of each individual's ongoing choices). But the situations that they find themselves in were a result of something they did.

Yeah, I keep hearing that, but - over 10+ jobs - have never experienced it.

Maybe I screen out those jobs in my searches. Or they screen me out :)

My bigger point is that there are many different SW engineering worlds even in SV. You, and everyone you know, may be in the one you describe.

But there are other and better ones out here. One caveat: You may have to "level up" to join some of them.
