Their efficiency goes way down the colder it gets. They’ll work well at 5-10C, but frost up and require electrically-expensive defrost cycles when it’s colder than -2 or -3 C.
This has always bugged me: what reasons outside of convention do we have for preferring O(V + E) to O(E) on algorithms that only make sense in the context of a single connected component? I know this is slightly OT, but tangentially related.
Hence the spin-off app. A ground-up, UX focused app which does not have to meet feature parity, would attract users who are already confused by email clients.

This is a different target audience to the people who typically use Thunderbird at this time.

For some people Apple Mail is enough.
> your system is distributed

if you don't have a shared data store, or its not fast enough, then you're doing the wrong thing with the wrong tools

> you don't want to be keeping a decryption key secure and in-sync across many (and potentially less-trusted) nodes

keeping shared secrets, which are very high read:write ratio, and change daily or less, should be childs play. If its not, then your security protocols are wrong. Key rotation must be simple and quick if you want your system to scale. When you get to 100 people, you'll be leaking keys weekly.

KMS, Vault and a few others are your friend here. There are off the shelf systems for this.

> the JWT contains attributes useful to the system (e.g. role, user ID, etc.)

having these public can be alright, assuming that you've properly mapped, scrubbed and checked for leakage. However, you shouldn't be reliant on user supplied stuff for this. You simply cannot trust the user.

If you need jwt for caching data, then you have a much bigger architectural problem. The stuff you are storing in JWT needs to be easily and quickly accessed. If its not, you either have a DB or a messaging system issue.

Now, if you are encrypting the whole token, then its less of an issue. But, using it to store anything other than a UUID and a issue time, you are asking for trouble.
Learning from data to predict future symptoms of oncology patients
One optimization is to break a scene into chunks. First you see which chunk a ray intersects and then test a Ray vs each object in that chunk.

This lets you avoid testing most objects for intersections but adds book keeping overhead so it only works really well for specific kinds of scenes. Aka not the classic single ball and a few walls.

Their are also multiple ways to handle chunks. For a space RTS game you might box up all the ships in a squad and first test the box around the squad before testing each ship. For Minecraft you can just split the world into arbitrary boxes that don’t change frequently.
This sort of pseudo science is usually upvoted/supported only because of bacon's popular conception to be unhealthy. That may be true, but your logic is still flawed since there is no correlation between cholesterol or fat consumption and heart diseases (as pointed out by other commenters). However, high glycemic nature of sugar is still based on facts.

I'd desugar it like this:

>>> lookup = {}
>>> for (x, lookup[x]) in ('ab', 'cd', 'ef'):
... pass
...
>>> lookup
{'a': 'b', 'c': 'd', 'e': 'f'}

This makes is much more clear that there is just a double assignment, and that comprehension are pretty close to regular `for` statement.

(this was a great example btw -- I write python3 a lot, and I was staring at it for a long time before Icould figure it out)
FreeCAD is quite workable, I've constructed some 100 parts for 3d-printing, lasercutting and CNC in it. There are some warts in the UI for sure, but once you get to know them not that hard to deal with. Quite a bit fewer learning resources online compared to Fusion360, but enough videos on Youtube to get started, and the FreeCAD Forum is pretty helpful.

For programmers, one can also use Python to define more complex parts or workflows.

Nirrius Studio | Front-end developer | New York, NY | INTERNS | PART-TIME | https://nirri.us

WHO WE ARE:

Nirrius is a consultant firm specializing in web development and technical mentorship. Our journey started with training developers with industry standards such as React/Redux and Node.js. Our mission is to perfect the front-end web development experience.

WHAT WE'RE BUILDING:

2018 generated the most buzzwords in web development history. Developers are expected to know React, Redux, Sagas, Webpack, Babel — the list goes on... These tools have served our growing demands of the front-end, but they always have a rise and fall. A library reaches popularity, and the web browser catches up.

We believe browsers have reached another level of maturity. And a simpler, native approach web development is within reach.

We call it: <my-app /> — An open source native web components library and framework.

WHO YOU ARE:

- You are determined, a self-starter, and in active pursuit of new knowledge and experience.

- You have some web development experience and are looking to expand your skill set.

- You're ready for three months of training in front-end, dev-ops, content writing, and developer relations.

Send us your resume and tell us what you'd like to study at teffen @ nirri.us with "Hacker News" in the subject line.

Infrastructure can't be sustainably paid for by usage fees. There are too many externalities for any individual person to have to shoulder.

The benefits of a transit system accrue to people who aren't using it as much as to people who are. A bus that transports 60 people means you just took at least 30 vehicles off the road (and that's a super conservative estimate). That extra capacity is a benefit to people riding bikes, walking, and driving. So why would you expect only the bus rider expected to pay into the system while everyone else benefits?
But it does clue you into whether the professor used a different set of assumptions than you did.

Obviously there are different scales when it comes to farming operations.

I like to categorize it as sub 50 acres(5-50 acres), sub 100 acres and sub 1000 acres.

Margins are still low.

It becomes more capital intensive and access to land and labour are also factors.
This is functionally equivalent to being given negative marks for getting answers wrong, which I've seen on multiple choice tests.
Heat pump with outside temperatures below zero has same or lower efficiency than resistive heating.
I'm sure of the US govt increased the federal tax credit for EVs from $7.5k to $40-60k, you'd see similar adoption in the US too.

I get your point, but to be fair, the numbers in your comparison are a bit off, since a $40-60k tax credit would make many electric cars effectively free. That would be a much bigger incentive than what Norway has.
or it's testing for people who have the ability to 'meta up a level and see they follow a pattern' which is part of what we call IQ.
Agreed. I love Thunderbird, and gave it a shot last year as my work email client (exchange). Loved almost everything, but ultimately the search and lack of threading sent me back to outlook web access.
>> It abuses platforms that do not implement the BIOS Write Lock mechanism incorrectly

I agree that post-boot the BIOS should be read-only.

> The UEFI payload would work on Linux systems, yes. But the delivery system described would not.

There was a case of rm -rf / erasing UEFI variables on linux system, rendering the system unbootable. Mapping the BIOS into the file-system doesn't strike me as too clever, but then again what do I know.
"Arendt’s notion is that labor—the realm of metabolism, maintenance, and consumption—has colonized and supplanted work—the realm of craft, fabrication, and use. "

Could somebody explain what this sentence means?
Without knowing the details of what your example did: You probably didn't have 75+ retail locations, didn't need to do the kind of marketing effort a quick-growing consumer/fashion brand requires, might have needed less customer support (due to having fewer, larger customers, unless you did very custom things), had less logistics overhead than a company that ships frames to people to try on and return. They also do parts of the production chain in-house.
I agree as well. Maybe it serves to alert the reader to when they are missing a piece of prerequisite knowledge, but there are ways to do this that don't create as much friction.
This is a great resource. Though it is dated this month, there seems to have been a mention of it two years ago and a short HN discussion ensued:

Except when it comes to Vim. Amiright? jk

But really though, this is solid, sound advice. And it's a great way to relate it back to business value. The extra half-second incurred when it comes to additional typing is going to be far less than the time saved when it comes to clarity gained from looking at the code again. Whether that be for future development, debugging, or whatever else.
I think it's to offset the price of manufacturing such that its no longer viable to skip on the electrical side of things due to the lower marginal costs and even if there is skimping, it would be easier for the host device to workaround it.

The cynic in me thinks that having so many turing complete microcontrollers with not insignificant performance and storage is going to be the NSA and other spy agencies wet dream. You wouldn't plug a strange USB into your phone or computer but you'd probably plug a strange cable or charger around your office/house or off Amazon - and that's if you could even tell the difference at a glance.
Why the reddit link that links to medium?

Mortgage brokers also don't include the mortgage interest deduction when marketing mortgage rates or mortgage products, so it's not comparable.

Heck, they didn't even want to do that! They did end up working hard (according to them), but the plan was that it would be essentially free money.

Only path forward is to share the market. Japan and Europe will enter the market in a big way without the logistics friction Tesla is so often in the news for.

There aren't good tech resources because GDPR isn't tech driven. You have to start from a legal standpoint. The tech will present itself from there, highly dependent on your architecture.

There are of course some basic things you can do without understanding the legal, like how to store PII.

The example questions you have are poor. The first one depends on your infra, entirely. The second on depends on a) details you haven't supplied and b) legal structure around the data itself.

You need a consultant.
It's working OK for me (via the Provider for Google Calendar add-on), though I haven't tried starting hangouts.
So with this technology will Google be able to scan anything in the room, including the gestures? If this technology is used the same way microphones are used in IOT devices like Alexa I have some concerns.
I think I agree with you with the caveat that it would depend on what they're researching. If they're researching new model architectures, I don't think it makes sense for them to try to implement the algorithms from scratch in C++/CUDA to do distributed GPU training--why not just use TensorFlow? But if you're researching distributed tensor computation, then that's your bread and butter.

I didn't realize they had retail locations, the employee count makes much more sense when you're running retail locations. I thought they were just a mail order company.

I think what really threw me off was "welcome balloons on desks" which heavily implies (at least to me) all of employees have desk jobs.
>That's why I prefer dynamically typed languages for web systems; they start with the rigth assumption about the ever-evolving nature of the project.

The inverse can be said: a statically typed language makes it easier to replace parts later, do automatic refactorings, etc., and know you got everything right.

Dynamic just let you have less ceremony (no type definitions) but forces you to keep this all in your head (you still don't want to pass the wrong type of thing to the wrong receiver) and doesn't give you any assurances.

With type inference and/or autocomplete, statically typed languages are faster to write and easier to get right than dynamic.

Essential is the contribution of Les Paul: https://www.historyofrecording.com/Les_Paul.html
Ottawa managed this by building a massive BRT system with its own roads and off grade bypasses, as well as dedicated lanes in the downtown area. They're beginning to implement light rail [1], which is fairly simple for them as they can upgrade the existing BRT lines with rail, increasing the capacity and decreasing maintenance costs. As you said, they faced initial political opposition, but I think the political will problem is a one-time cost -- once you have the network in place and the benefits are realized it becomes easy to change or upgrade it.

Both BRT and LRT don't necessarily solve the first- and last-mile problems, though. Many US cities are using park-and-ride stations, but that can just spread traffic out instead of eliminating it. It's important to create networks for short trips to and from transit stations with things like bikes and scooters.

I've been a generalist for the past 10 years spreading my time over network administration, desk side support / service desk, and teaching network administration. I've worked with a little bit of everything, but mostly maintaining Windows hybrid environments.

For the past couple of years I've been focused on building cyber security skills, and most recently working through security and ethical hacking training and full-stack web development CBT courses. Some samples of my work are on http://timwatkins.win, or I'm more than happy to send some your way.
>Everybody surely have cheap electric scooters and bikes or other electric devices and airbag helmets. Few, if any, combustion engine cars are left on the streets. Truly self driving cars are likely too.

None of those are mass transit. Personal vehicles are fine and dandy, but they can only move one person at a time and will always, by definition, take up more space and resources per person than a solution that can ferry tens or hundreds of people at a time.
I believe this is also partly why the early Apple computers cost much more than the equivalent IBM PC/XT/AT --- the latter did not make use of custom chip designs, instead using standard off-the-shelf parts. (This also made them easier to clone... and the rest is history.)
It’s a re-hash of the “start an Internet business and make millions of dollars from home” scam [1].

I always thought the search was excellent when I used it. At one point I had a 100k of emails. But I could find what ever I needed. Meanwhile Outlook failed with a certain local file size limit and caused endless problems. They were apparently okay with that and resisted change to something that actually worked.
