It has to do with how to hit a consumer price point with a receiver for a complex modulation scheme using only a couple dozen active devices and cheap-to-manufacture filters.

Original NTSC monochrome television is a 6 MHz wide channel, the video carrier is 1.25 MHz up from the bottom, and at the transmitter a filter lops off most of the lower sideband.

For receivers, the problem is the IF filter. Filters with steep skirts are hard to build and align, and are expensive. So... channel allocation was done with the assumption that most consumers would have receiving sets with poor adjacent-channel rejection because of using cheap filters. This was solved by channel allocation -- do not let two stations with overlapping grade-A signal contours be on adjacent channels. Problem solved.

In the very early days in the US, channel 1 was 48-54 MHz. They found out that the percentage bandwidth was too wide to be able to build a practical transmitting antenna for channel 1. The SWR was too high at the band edges, and high SWR on analog TV means the transmission line generates ghost pictures. So channel 1 was dropped. Now hams have the 6 meter 50-54 MHz band, and cheap license-free R/C toys and walkie-talkies have 48-50 MHz.

Channel 2 is 54-60, 3: 60-66, 4: 66-72 and then a gap: 72-74 is radio control, then channel 5 is 74-80, and so forth, and if I recall correctly there is a big gap between channels 7 and 8 so even though they are sequential numbers they are not frequency-adjacent channels. (7 and below being the so-called "low VHF" and 8-13 the "high VHF" TV channels.)

The 2 MHz gap between channels 4 and 5 was also used to advantage, as it was enough to eliminate the adjacent-channel interference problem on reception. I recall when I lived in Minneapolis, that channels 2, 4, and 5 were all allocated in the metro area. Channel 3 was Mankato, far enough away that if you lived between Minneapolis and Mankato you could receive all of those stations without interference problems, being in the grade-B signal contour of both.

And..... this entire post contains obsolete information of historical interest only, and even at that, of interest to very few. Now... excuse me because I have to readjust the spark gap on my 200 meter transmitter...
There's a lot of code out there that's important, but not worth porting to a new language (which Python 3 is).
There isn’t anything inherently wrong with still using 2.7.x . Just don’t expect updates. For new code using 3.7 is probably the best bet at this time.
...so how much would it have improved the reception if they kept using the same amount of power for digital?
EU data portal launches to support Covid-19 research
I honestly don't even know if I can fathom how you could get permitted to build such a tank in a couple of weeks, but the answer to why that isn't happening _right now_ is probably because nobody wants to lay out a bunch of capital for a business that might do well contemporaneously but that has no future.

Either things settle back down to normal at some point, in which case you've made some revenue, but probably not recouped your investment. The Cushing facility managed to build 7 million bbl capacity in the early 90s for $60 million. I expect it would cost $80-100 million to build today. Current (inflated) storage costs are 50 cents per barrel. Let's say that rises a LOT and skyrockets to $2 - that's a gross of $14 million per month. Assuming $0 in overhead, you'd need for this contango to last for another 7 months to break even. If we assume something like a 30% margin, then you'd need it to last around two years.

Alternately, things don't return to normal. The market becomes depressed enough that airliners barely fly, and the global world consumption falls. The oil you're storing becomes cheaper to the point that storing it costs more than buying it, and there's nobody to sell it to. Your customers default, and your investment quickly becomes the thing that bankrupts you.
The JetBrains IDEs implement their own raw keyboard event handling, which means that if you have your system set up with a non-standard keyboard layout and JetBrains hasn't implemented their own support, it just won't work.

The issue on their public issue tracker has been open for something like 8 years.

Unfortunately for me this means that no keyboard shortcuts using the Cmd key work, despite me using a built-in macOS keyboard layout with no special customisation.
Backhoes are cheap. Maybe environmental issues? I imagine someone would have a problem if I just dug a hole and filled it.
They have been trying to sell, but none was buying. The closer you get to the expiration date, the lower you are willing to go to sell. Since contracts expire tomorrow, traders are willing to go all the way to avoid getting physical delivery.
This is due to more of a market structure issue - the May contract expires tomorrow and the negative price really just reflects the price of storing crude. Why? There's nowhere to store it, demand is incredibly low, tankers and reserves are all filled up thus whoever holds the contract on settlement is responsible for storage, thus the negative price. Look at the June contract for something more accurate.

That being said, I expect something like this to transpire for June as well, possibly earlier than just a day from expiry, so long as production stays above 0 and demand stays as low if not lower.

A shirt is an item of clothing. Items of clothing are made from material. Some materials have patterns. One type of pattern is stripes.

Seems like a matter for logical inference. At which point it becomes fairly easy to find shirts made from material where that materials pattern is not stripes.

But yes, no AI I have seen works reliably on even basic queries like this.
I meant this more in the sense of do they look at a specific benchmark to derive how prices are set.

E.g, If gas is based on WTI, then Brent can be up or down without affecting it much - Prepared to be wrong.

While they aren't in lockstep, it looks like they play off each other most of the time. As you say, seasonality has a role and demand for heating oil v gas depends on the time of the year.

Went on a garbage plant tour a few months back and we were advised not to practice optimistic recycling for this matter.

With plastics, if it's not hard plastic, don't hope it will be recycled. Soft plastics like bags end up gumming up the machines. Sure you can bundle the bags together in a ball and supposedly the waste collector will process it separately (i.e. outsource it to someone else), but the general public is better served with fewer exceptions. Just assume that any plastics aside from bottles and cartons are not recyclable.

Reduce, reuse, then recycle.

If I remember correctly, in contrast to WTI, you will get assigned a shipping/warehouse certificate for wheat/corn in a designated elevator somewhere. You'll have to pay the warehouse a daily carry cost but don't actually have to take it out of that warehouse (you can if you want to).
The same happened all over europe. European countries seizing equipment in transit toward other european countries. Even France did it (despite Macron's insistance on European cooperation).
With that read, most European countries have UBI and then some. I assure you, the proponents of UBI in Europe will violently disagree.

Btw...checked out your open source apps. Nice work. I just wish industry was bigger into building their own tools (like was common in the 80s when everyone wrote their own loadflow tools) instead of being reliant upon vendors for everything. There are advantages though to both.

I find remote code editing to be useful when I don't have the necessary resources on my machine such as disk/memory/gpu and I am still prototyping a solution, which happens a lot in ML/DL.

I agree that remote code editing is not strictly necessary since you can perform such task with sshfs or git push/pull workflows.

On the other hand, having the remote environment in your local IDE quickens the development and you don't have to setup a full replica of your environment locally.

edit: ML/DL here stands for Machine Learning/Deep Learning
I'm aware of that, and if there were a risk of acts of hatred against Spanish folk by me using that name today, I'd agree, however we're talking about a pandemic that spanned 1918 and 1919, with the second wave in 1919. Using "Spanish Flu" is, however, clear and well understood.

"Can we do it without moving to where you are?"

Sorry, no. We tried this once, and by Demo Day that startup was way behind the rest. What we do, we have to do in person. We would not be doing a startup a favor by not making them come to YC events in person.

However, you don't have to be in silicon valley 24x7. If you have a business that requires that you be somewhere else, we will work something out so you can participate in YC events while also being attentive to your business. Usually the founders will rotate between locations, or fly back and forth.

Of course, after the 3 month program, you can go wherever you want.

It's a good question, but a number of producers are trying to put others out of business. I don't know that this was necessary considering the drop off in consumption, but perhaps the point is to generate a supply shock in order to make a bigger point.
I wish there was some sort of scoring system for product packaging that would take into account the quantity and environmental impact of the packaging. Like, if the product comes in a small cardboard box it gets a good score, but if that cardboard is lined with a plastic film (effectively making the cardboard non-recyclable) then the score goes way down.

That score could then be used by consumers to make informed decisions or maybe it's used to charge producers to cover the cost of safe disposal of the packaging when it reaches its end of life.

Right now, I'd say become familiar with the /r/hackintosh subreddit and it's accompanying Discord. You can suss together a "golden" build there.

I specifically recommending avoiding anything on tonymacx86 across the board. One, their methods involve a lot of ill-advised hacks and two, their hardware builds often lag and are specced with the aforementioned hacks in mind.

The tl;dr version of parts selection:

- Get a non-oddball Intel CPU, such as a 9700K or whatever,

- An AMD GPU (an TX 580 or 5700XT),

- A Z370 or Z390 motherboard from a reputable manufacturer, such as ASUS or Gigabyte.

- A fast NVMe SSD, because that's what macOS expects these days.

- For AirDrop and certain other macOS features, you'll need a well-supported BT/wifi card.

When I built my system, I specced an 8700K, an ASUS Z390-I Gaming, a Sapphire RX 580 Nitro+, and a Samsung 970 EVO Plus SSD. I had to swap out the mini-m.2 intel-based wifi card from the motherboard and installed a Dell DW1560 and that was a little annoying, ut it's a one-and-done thing. And dang has my system worked great.

How to Write a Good Comment
Epic is kind of a thorn in the side for me when gaming (on a Linux distribution). There are a few Epic exclusive games that I'd like to play (Arise: a simple story, Journey, etc.), but they don't even have entries in protondb.

That's probably due to Epic not having a launcher for Linux. A few months ago(?), I read it had become possible to run the launcher through Wine, but I don't think that's changed anything on the porting side.

I worry that games which are released as Epic exclusives may fall by the wayside when/if they eventually become nonexclusive.
Yeah, it's worth building these tanks safely.
There was tank fire last year in Bay Area after a quake: https://www.youtube.com/watch?reload=9&v=KMZjfWRXgTs
Even if there is different level of risk and safety concern, and air quality regulation in rural Oklahoma vs urban CA bordering a highway, these can catch fire dramatically.

One point made when that fire occurred was that the tanks are placed in earthen basins, so that when tank fails, the flaming fuel just fills the basin, minimizing risk of spreading to neighboring tanks.

They are being reallocated (with strong indications being that it's for political gain by the current administration and to help vulnerable congressional candidates) or given to private entities.

LA Times originally reported government seizures of PPE weeks ago.

In separate news from a different source (PBS Newshour), some hospitals are reporting protective gear from state and federal stockpiles that is completely unusable: masks 10 years past its expiration date, masks for children, masks that are rotting [1].

My guess: These two stories are related. The government had enough masks / PPE on paper, but never actually checked it was usable. No one intended this to happen, it just sort of fell through the cracks, and all the paperwork said everything was OK.

Now that huge amounts of physical masks are actually needed, they can't get by anymore on paperwork that doesn't reflect reality.

The stockpile probably has a (not officially acknowledged) main purpose of protecting the essential parts of government if there's an outbreak: soldiers, intelligence, Congress, etc.

Since people actually started physically checking the masks in government stockpiles, behind the scenes bureaucrats have been panicking because they suddenly found out there won't be enough PPE to protect the government, and the market's so tight and the supply chain is so stretched that they just can't simply buy it, there's way too much demand.

So they've decided they need to rebuild the stockpile. The government's reasoning is probably that what really matters is that the "people who matter" in government have what they need. If civilian doctors get sick, and some of them die, that's (seen by government bureaucrats as) an acceptable price to pay to be sure the government itself is protected.

This sounds pretty horrible, but I'm not sure they're completely wrong. For example, what if Russia invades Europe or China lands troops in California next week, the US Army starts to deploy in response, but gets paralyzed by a huge coronavirus outbreak and all available PPE's already been used?

Seems to me like this kind of ethical question should go through the public political process. I'm not sure why they aren't simply honest about why they're doing it. Trying to hide it suggests some bad motive. Maybe it's to hide the original screwup of not checking the stockpile properly. Maybe they have OPSEC concerns about not tipping our adversaries off that this would be a great week to start a war, since the US Military's effectiveness is temporarily crippled by lack of masks.

Anyone know how to file an FOIA request to try to force the government to tell us what's happening to seized masks?

Hi there,

my friend and I have build a Slack bot for automated Social Media analytics and reports. It's a fast and simple way to keep track of your companies Social Media health across all of your accounts.

We wanted to have a tool that is easy to use for none Social Media people and can be integrated into daily team communication.

I would love to hear your feedback on it!
I phrased my comment poorly. I understand this.

Do you care to address what my comment clearly intended to articulate, specifically that if you care about something like how companies treat their employees it’s worth the small effort to do some background research? I’m not sure how that’s outrageous or smug.

Do you feel that there are no limits in this regard?

Is it not ok to care about such things and factor it into decisions made as a consumer? Why is this a hot-button issue?
The context here is oil - the benchmark contract and the one referenced in the article is the NYMEX CL (WTI/Cushing) it’s a deliverable contract.

"Discarded single-use plastics have become an international environmental flashpoint, as they have turned up in the bellies of birds and fish, flooded pristine beaches in remote countries with litter and even been detected in microscopic quantities in rainwater."

Ironically, this is almost certainly due to recycling being so uneconomical that trash gets shipped to foreign countries, where less diligent actors will simply dump in the ocean.

Landfills are the best solution, let the trash robots of the future figure it all out.
I agree with search getting worse, now I always have to add quotes around my keywords: yes, I really wanted to search for this exact thing.

Well, in many parts of the country that additional room would not be very expensive to build or you could just buy a place with extra bedrooms. In the bay area though, it's definitely a luxury.
Oh no, I agree! He was definitely ruthless during his reign as the head of Microsoft. Generally, when one can show such disregard than one has an overall character allowing for that, so it's rare that people would behave differently when it comes to their wealth. But, of course, people can change - even if it is out of a feeling of guilt.
"If you want communism, go to China!!" - They should be yelling it to people who have concocted communism state for large companies/industries. Take airlines for example - they're getting this giant bailout at taxpayer's expense. Those were running profit for the last 10 years and managed to save nothing for the rainy days. Now they're crying and want taxpayers to bail them out.
The original study was on the HN front page twice; biggest thread:

https://news.ycombinator.com/item?id=22899272

This analysis is pretty damning, and is more credible in context (the topline findings of the original study constituted extraordinary claims, which, if extrapolated, could imply that a majority of all New Yorkers had C19 antibodies).

Some of the underlying ideas here are pretty straightforward. For instance, the fact that even with 90+% specificity, if your rate of false positives exceeds the true positives in the population (as can happen even with good tests when the underlying condition is rare, as it is with C19), you're going to have problems.
Most of those events are unrelated violence that just happens to be near institutions, not actual shootings. This includes gang-on-gang violence nearby, people shooting themselves in their car, accidental discharges, etc. Look at the actual numbers involved and the descriptions of the events themselves. There's a lot of interest in making it seem worse than it is, as you've clearly demonstrated.
Please see my reply above. I phrased my comment poorly. Do you feel that there are no limits to who it’s ok to do business with?
Not really , Chinese demand had dropped sharply in late January due civoid shutdowns . The original production cut discussions were influenced by that significantly.

Saudi/Russia likely did not anticipate a global lockdown and decided to get into a price war to keep their absolute revenue numbers stable albeit by increasing production under reduced prices ,that has of course backfired spectacularly.
