Not Europe, but unfortunately, my state of Massachusetts has terrible electric costs for complicated reasons, so I understand what the OP is saying. I had to keep explaining this to my friends in MA - I replaced a Prius with a Nissan Leaf and my running costs are far higher.

(note that these prices are yearly averages for the state selected, but you can also fill in your own values since things change)

70,000 - 8800 (married filing jointly) - 2000 (two dependents) = $59200 taxable income, $2960 tax bill. An effective rate of 4.22%

To reach the site's stated 3.29%, this family would need to make around 32k a year.

Fwiw, it appears the average household income in Massachusetts is about 80k.

" Customers that have 5 or more End Users will receive a total amount of Google Drive storage equal to 5TB times the number of End Users, with more storage available at Google's discretion upon reasonable request to Google. "

Existing customers (under G-suite) may be grandfathered for an arbitrarily long time, in which case I would agree you don't need to worry.

" Customers that have 5 or more End Users will receive a total amount of Google Drive storage equal to 5TB times the number of End Users, with more storage available at Google's discretion upon reasonable request to Google. "

That is new behavior, and rubbing some people the wrong way.

I think the more curious thing is how long will they grandfather in the existing Gsuite users to the old, "unlimited" behavior. If they do that for long enough, at least it wouldn't feel like a bait-and-switch.

Such an interesting contrast to this frontpage post yesterday:

"The highways themselves were specifically intended to facilitate the reasonable objective of Houstonians not to get annihilated by a nuclear blast...[In] case of atomic attack on our key cities, the road net must permit quick evacuation of target areas"

(Discussion: https://news.ycombinator.com/item?id=24331698)

So one might ask, if all these highways don't even permit quick transit, what the heck are they doing?

Natural gas is roughly $15 for 1 million BTU. There are 3412 BTU in a kwhr, so if you heated resistively, you'd need 293 kwhr to get 1 million BTU.

In my area, which I feel has pretty high electricity cost, we pay $.24 per kwhr, so that'd be $70.

Therefore, you need a 70/15 (4.666) COP for your heat pump to match natural gas by price. My understanding is that that would be an unusually high number for cold weather conditions.

When the laptop screen eventually gave up (I think just the connector) I never ended up rebuilding it. Nowadays you can get a really awesome looking projector setup for so little, it's not really worth trying the same approach.

But from what I skimmed through, this is a build of way higher complexity, cost, and quality. I'm looking forward to watching this video tonight.

I looked at the 2020 Macbook Air (the $~1300 model), and it seems to offer the same or better specs (depending how much you value the display) for the price. Are we at the point where we must pay a premium NOT to run OSX, or am I missing something? I don't love the direction OSX has headed, but I'm still content enough running it and using Linux remotely where needed.

For the i5, they claim 1.1/3.5 which could be a match for https://ark.intel.com/content/www/us/en/ark/products/197119/... with the "configurable TDP" of 1.1 instead of base 800 MHZ.

If anyone can solve this mystery, it would be great to compare to other laptops like the Surface Pro, whose i7 is "Quad-core 10th Gen Intel® Core™ i7-1065G7 Processor"(1.3 / 3.9)

perl -lane # process input by line, split into fields, print outputs with new lines, execute code

netstat -planet # show process, extended info, all socket types

ss -pimento # basically every piece of info about live connections

iostat -txyz # extended, omit first report (the since-boot one), omit devices with no activity, log datetime

Personally, I'm pessimistic that any metric about productivity can be useful in the long term, but I recognize that in this reality, there WILL be metrics used to judge you. So, what's the best way to handle this? Is there anything an individual contributor can do to guide towards better metrics, or even just the perception of such?

So, a bloom filter can tell you whether it's worth spending the expensive check to verify that the block is a duplicate, or whether you should skip that behavior and move on directly.

Same is true for malicious site detection. Google offers this feature in Chrome, but we don't want to make an expensive network request for every URL we visit. And we can't really have a database of all malicious URLs downloaded and updated to everyone's computer. Instead, they can distribute a bloom filter of malicious sites. if the bloom filter says it's malicious, we can afford to check the network for the final answer. If the bloom filter says it's not, we know we don't have to check (and that's the most common case, too!)

In my opinion, the intuition to extract is this. If you need to check membership, the set is expensive to check, and getting a definitive NO is valuable, then you can consider a bloom filter (or another probabilistic structure like a cuckoo filter). In dedup, we need to check membership, the index is big enough to not fit in RAM so it's expensive, and getting a definitive NO means we can skip the index check. In malicious site detection, we need to check membership, the answer requires a network round trip so it's expensive, and getting a definitive NO means we can just move on to loading the site.

Of course, once we start optimizing how the original array is stored, we may have exceeded the limits of this problem as a teaching exercise :)

As for time, it does seem to be O(n) to me; can you clarify why you think it's nlogn? It may not be particularly fast in practice when compared to other O(n) approaches like the bitmap, but I don't think the complexity is wrong.

Your solution is nice - it actually gives you more information (how many appearances, not just T/F >1 appearance), but it does require more additional space and isn't necessarily faster. I think the bitmap approach would be nicer if you're ok with using more space; the bitmap is essentially a very easy to find perfect hash function due to the unique input constraints.

So, I think you're doing fine unless you want to spend more money :)

If you're brewing espresso, where the freshness of the grind is integral to the texture of the result, maybe this is less true. But anyone who's taking espresso seriously has a nice grinder anyway, I guess. (And on the opposite, I think French Press is very tolerant)

Speaking of which, does your model not have a resistive backup? Ours has several modes:

- only use heat pump, unless not safe to do so (ambient too cold) - use heat pump normally but fall back to resistive to recover - use resistive only

We only have 2 people in the house so we are able to leave it on the first mode, but in the second mode it would, presumably, be the same performance as our old resistive-only heater.

In these settings, music with lots of dynamic range may legitimately not sound as good. Due to the quality of reproduction, the low-loudness parts are hard to perceive.

For me, there are certainly songs that I enjoy listening to on good headphones in a quiet room that don't have anywhere near the impact when played on laptop speakers.

Tesla Model 3: 26 kwhr / 100 mi Model S: 33 kwhr / 100 mi Model X: 39 kwhr / 100 mi

Hard to say where the balance of supercharging comes from (more expensive models more likely to have it free, but maybe less likely to use?) so let's be generous and call it 30 kwhr/100mi

I pay 24 cents per kwhr but I hope their average price is more like 10 cents (not even counting the solar...)

So each 100 miles charged would cost $3.

So 100 million dollars spent giving out electricity would generate 3.3 billion miles charged.

Back in september there were 20 million telsa miles driven per day, but a year long projection would be hard given the fast growth of model 3. let's just say 20M per day. That's about half of the year's miles driven covered with 100M.

I can't imagine that even 1/2 of the total miles driven are charged by superchargers. So I am inclined to agree with you; the free-supercharging-electricity costs are probably a small piece of the total 500M.
