A few solid cases are:

- space-qualification for the satellite control software. You need to test your own flight software in space, so you use our satellite platform to run test/validation and then reuse on your own satellite.

- space-based algorithm tests, such as data compression/error correction or radiation hardening through software means. Inter-satellite link protocols is also a rich field for software developers.

- data analysis: satellite instruments can produce a lot more data than can be downlinked, so it is in your best interest to pre-process it as much as possible on-board instead of downloading just raw data

- Autonomy algorithms tests: for example for automatic collision avoidance software or maneuvres around non-cooperating target (think defunct satellite or asteroid)

- Data fusion: combine data from multiple satellite instruments, such AIS receiver and imagery to filter maritime traffic for ships without AIS transponders on, then classify those

- Remote asset tracking and labeling (think pipelines, agriculture, shipping containers, farming plots) where you don't have "eyes on the ground". Needs some image recognition tools to identify changes and/or damage.

All of the above can be packed as an "app" and run concurrently or in series on one or multiple satellites, with the possibility of reusing the code for different satellite platforms.

An interesting case is making a single "virtual satellite" out of multiple physical ones, with a single app using instruments from different satellites.
Source?

AFAIK traditional artificial light sources do indeed dissipate much more energy for the same amount of 'useful light', and also produce so much heat that they cannot be placed near the plant.

Is artificial light mandatory in urban farming? Aren't some (non fiber-optics-based) "light tubes" able to transmit light along with the necessary UV?
"My company, like most, is leveraged". Which is exactly why they should have never even exist in the first place. You and the ones you're refering to are part of the bigger problem. This is just a cycle and it will happen again.
The entire world is shutdown. I don't understand how we can avoid a recession at this point. I think Cash will be king so companies that generate a lot of it like apple, google, fb, msft will be fine. A lot business that don't generate cash are going to be in a lot of trouble. As money dries up funding is going to be harder to come by.
> AWS should have a cost cap. Set a max spend value and shut down all servers if you spent it.

That might make sense for some particular services (e.g., capping the cost on active EC2 instances) but lots of AWS costs of data storage costs, and you probably don't want all your data deleted because you ran too many EC2 instances and hit your budget cap.

Where exactly you are willing to shut off to avoid excess spend and what you don't want to sacrifice automatically varies from customer to customer, so there's no good one-size-fits-all automated solution.
Galois would be happy to know how important his work on finite fields was to discovering and formalizing cryptography, both for the ways in which it has empowered political revoloutionaries, and also for the irony that it is one of the most applied maths in the world.

As a cryptographer once said to me in jest, "I wish I were able to make an impact like Galois. But if I were Galois, I'd already be dead."
I might be within the law (although in some places like BC all reselling is straight up illegal) but some busybody would still call the cops on me and online listings would be taken down by the likes of amazon or ebay.
Monitoring My Servers with Telegraf, InfluxDB and Grafana
ESP8266s aren't very pleasant to work with, and in my experience it can be hard to accomplish much in program logic while keeping the WiFi stable.

But the cottage industry around these addressable LED driver boards is getting pretty ridiculous. The PixelBlaze already does a great job of controlling them from an ESP8266. And the LEDs aren't that hard to use with generic hardware like Arduinos, even for people with zero prior experience.

There's no doubt about it, this world caters to the hucksters and the unrealistically optimistic.
Good grief, please don't replace one unnecessary flamewar with another, nationalistic, one. That's heading in just the wrong direction.

This is a false choice. Urban agriculture doesn't need to mean indoor agriculture / relying on excessive electricity / complex equipment etc.

Cities can be plenty dense while still having enough space for people to grow potatoes for themselves and their neighbors.
I approached K8s specifically from the point of Ops. It simplifies the story of supporting many applications immensely, in fact my first production deployment was done explicitly due to that reason - we have over 60 applications, we can't really reduce that number without unholy mess of rewrites that isn't certain to reduce that number at all.

Come kubernetes, and we have a way to blackbox developer excesses, push 12 factor onto it, and generally out of over 60 present apps, we have reduced our workload to really caring about maybe 5 classes of them, as they are commonalized enough that we can forget them most of the time.

At different job, we're pushing heavily towards standarized applications, to the point of Ops writing frameworks for the devs to use - thanks to k8s we get to easily leverage that, compared to spending lots and lots of time on individual cases.
Another method, which has worked for me, is to never store passwords in the database at all but in a separate authenticator like Google Auth or AWS Cognito. Then the authenticated username is passed in via signed JWT. The database can perform authorization, but authentication (and authentication method) are kept far away from the data in your database.
I think it will prove hard to get proficient with SQL quickly, because you need to understand the relational model. I’ve interviewed people who tried to B.S. on relational/SQL questions, it was very obvious.

The point about displacing people and businesses is only true if real estate is in a fixed quantity. When building is a possibility this is not a zero sum game.

Given the (OP) solution, I was imagining having a broccoli wall in my apartment. This would give me a lot more insight into the farming practices as I would be growing it. Also, near zero transportation externalities.
I used `benny`. If you have a NodeJS setup you can easily run the benchmarks by:

npm install

And then:

node benchmark.js

That will start the asynchronous and synchronous benchmark sequentially.

Thanks for taking the interest.

Edit: benny uses the Benchmark.js library underneath.
We recently dropped slack and moved to teams when we started working from home. It seems to be mostly better than slack.
If you use Dollar Cost Averaging[1] there is no such thing as a good or bad time to buy ETFs. As long as the market goes up on average, which is has done throughout history, then you will win over a sufficiently long horizon. A popular phrase is "It's not about timing the market, but time in the market".

Make sure you research your ETFs and what they are tracking e.g most of the Vanguard ETFs (e.g. VOO, VTI, BND) are quite reliable but if you are investing (and not day trading) avoid leveraged and inverse/short ETFs such as SPXU and TQQQ. They may seem attractive now but they are based on derivative products so their pricing is subject to a number of factors.

$200k is about the threshold needed to qualify for a mortgage in the area he's living for a comfortable, but not luxurious single-family home.

That's also a good baseline for a standard-of-living where all necessities are met, without worrying about them, and where there isn't financial stress. However, it's not enough to get rich.

It's also a point where I don't feel like I'm making a significantly greater sacrifice than Khan would if he paid out of his own pocket (in other words, a signal that I care more about the organization than he does).

$100k would be okay in the midwest or rural America.
When you have to be extremely noise/fault tolerant (e.g. you can literally remove half a brain and still function normally [1]), you over-design and over-engineer the system with massive redundancies everywhere. We don't know how much information is actually encoded in these trillions of low precision synapses. Our best deep learning models tend to be very over-parametrized, and are highly compressible. A CPU is nowhere as fault tolerant but it does not have to be, because modern solid state electronics is extremely reliable (and has much wider ranges of operating conditions than human brains).

It’s excellent in the sense that no one has done this sort of analysis yet. We’re flying in the dark due to constraints of testing.

The hope would be that by publishing this work, more people in other cities are prompted to analyze excess deaths and note whether there are any abnormalities during the time the pandemic hit locally.
That's about as simple as it gets. This is a pediatric ICU ward, I just wanted a picture that shows you the essentials. It can get much more complex than that and not a whole lot simpler. Once you are intubated you are kept sedated (it's not exactly a pleasant experience) so you rely 100% on the world around you for your vitals and needs. Essentially you are in a controlled coma for the duration with all the difficulties that brings.
Which ETF? There are more ETFs than individual stocks [1]. Rather than time the market you are better off, in most cases for most people, just regularly buying broad indexes and periodically rebalancing, see [2]

What about HIV? 10 years "incubation" period and 100% mortality. If it was as contagious as the flu it would have killed almost 100% of the human population. Isn't it a scary thought?.

It is not the only virus. Rabies, also has 100% mortality.

I would say if you're interested in getting into passive investing it also makes sense to get into dollar cost averaging, or in other words invest a fixed amount of money into the stock market at regular intervals.

Passive ETF investing is like saying "I don't have an opinion as to which company will perform the best, so I am going to invest in all of them and be content with getting the average return of some index". Dollar cost averaging is like saying "I don't know if the market is overvalued or undervalued right now, so I am going to spread my investments out over time and be content with getting the average returns of the market over the next X number of years (where X would ideally be something like 20 to 30 years)."
Whenever you have the money to invest is the best time to invest in ETFs. (assuming passive index funds with a long term horizon and you understand your risk tolerance)

Timing the market for the "best price" is almost impossible.
The good news is that these are outliers; this is not typical behavior for any size church, mega or otherwise.
I am careful about giving financial advice to someone asking about timing the market. Things that might be helpful to ask first.

1. What is it about ETFs that makes you ask the question? Do you know what an ETF is, what it does, and what other financial products are out there that do similar things and how much they cost (fees)?

2. There are so many resources on the internet. I would say it's good to understand concepts like: Dollar-cost averaging, portfolio diversification, investment horizon, risk aversion. Most introductory investing resources would cover these things.

3. Think about what your short, medium, and long term cash and liquidity needs are to help determine how much you need/want/can invest. Remember, you can probably sell and get some money back, but it could be at a loss.

In summary, one could argue that it's always a "good" time to invest. The questions I would ask are "in what", "how much", and "how long".
+1 for dollar cost averaging if your funds are also coming in on a schedule (per paycheck).

However, if one had a million dollars sitting in the bank, it may not be prudent to dollar cost average. Portfolio management and a time horizon are necessary to achieve the desired mix

I live in Rhode Island, and it's been interesting to see my own gut reactions to this.

The short summary is:

- I'm sympathetic to their urge to escape ground zero.

- But I'm angry at those who put Rhode Islanders at greater risk when they ignore the stay-at-your-residence order from our governor.

- It's a little frightening to see the xenophobic and reactionary feelings this brings me. I feel a strong tug towards us-vs-them mentality.

A virus with a political inclination / motivation. That's a new one.
Currently, its a temporary waiver, so I wouldn't be too hopeful. Plus, I can see it at the state schools, but if we are talking the "prestige" schools then I would be damn mad because their biggest value is the contacts you make (or so I am told and observed).
>Power consumption grows with the square of frequency

You may be thinking of the power of a mechanical wave, which is composed of the kinetic energy of particles in e.g. a vibrating string. A CPU's power consumption is linear with regard to clock frequency, and I'd hazard a guess the brain is similar. If consumption were quadratic, you'd basically be able to get power-free computation by parallelizing to a large number of very slow processors.
Same. Disgrace sticks with me to this day.

There are exactly 6 known instances of talk down landings that I'm aware of. All concerned general aviation and in one of them the person had prior flight experience. Several of those ended in a crash. A general aviation plane is in no way comparable to a large airliner, and no instance of such a landing has ever been recorded, nor has it been attempted.

Life is not a movie, some stuff is just hard and requires a long time of training before we'll let you go 'solo'. One mistake and someone ends up dead, there are no do-overs, there is no undo button.

The last thing ICU's need right now is on top of all the stress already going on there to be overrun by eager rookies that are trying to help.

The best we can do - and this is happening in some places - is to move up the training schedule and to graduate ICU nurses early. This is need for several reasons: to man the extra ICU capacity that is coming online and to take the place of those who have died or can't take it anymore due to psychological stress.
> The max loan is $10M though.

This only pays for employees that make $100k or less for companies with less than 500 employees.

$100k / 12 * 500 = $4.1M.

If you have a monthly payroll of over $4M then you almost certainly don’t qualify for this program in the first place.
I think I read an article at one point that most "urban agriculture" and indoor farming tools were originally funded with the expectation that they would only be valuable for cannabis production. Because while you could grow tomatoes and lettuce indoors if you wanted to, it's really only economical to produce cannabis. I think that's still true today.
This has absolutely nothing to do with globbing. The title is very misleading – I was super excited to see a new glob library.

Almost all emergency-related profiteering is about non-artificial supply and demand issues. Grocery chains charging 10x as much for water or toilet paper is exactly the kind of thing these laws are meant to prevent.

(If the shortage is long-term, you'll usually want to implement a rationing system to address the shortages, but in the short term this kind of fiat can work.)
If we subtract the vm time from total time that should (very roughly) be the time taken for fdir to crawl the directory.

Not bad, not bad. :D the scale remains the same tho so not that beneficial.
The home carrier does need some information in order to charge the customer the correct amount (and apply any promotions for roaming rates when roaming in certain places).

Also, location data makes it easier to handle disputes in case customers see unexpected charges on their bill and dispute a charge. A place like "Kettleman City" might seem unfamiliar, but if your carrier could also show you that you made calls from Los Angeles the day before, you could reasonably conclude it was a call made while driving in California and not an erroneous charge.

So there is a balance to strike here.

The difference is the level of government access to the location data though. The legal standard in the US is that the government must obtain a warrant to access cell site location information[1].

In Saudi, telecoms are pretty much controlled by the government and can see everything.

Perhaps the best option for those who live in authoritarian countries is to remove your SIM card while roaming and have a voicemail message asking people to email you.

And then what? When you invest money, you have to have a purpose. "Making money" is not specific enough. When do you need the money by? For example, if you'd like to invest for retirement, and this assumes you'd make periodic deposits to your account, then it does not matter if you invest today or in a month since you wouldn't sell for (presumably) decades.
Good catch. Though I looked up the population of Nembro. Wikipedia has it at 11,518.

Don't forget the option to transmit into a dummy load (or to a radio receiver and/or a spectrum analyzer with a 30 dB in-line attenuator). It allows one to experiment with "illegal" radio setup. Although the transmitter itself still has RF leakage and may still violate radio regulations, it's much less disruptive (and technically you can make it perfectly legal if good shielding is added).
When doing largescale editing changes, I much prefer the single file approach.

Things like:

+ Changing the age of a character

+ Changing the argument order for a particular function

Those aren't simple find/replace solutions that you can run across files.

You can do the same thing with multiple files, but it's slower and can be harder to hold a context in your head.
