That's easy to say in hindsight. It could just as easily have gotten Hubble cancelled.
We’ll most likely have contact tracing and a good supply of tests in two months. As well as lot more ppe.

So a lot will be different in two months.
I think your question was misunderstood, as the other replies do not go into any details on diffraction limit at all.

I too would be interested in knowing if this image is showing all we got, or because someone else looked at it and said "sure you can release it, we've got better than that anyway."
> I think I definitely would have taken the 3m mirror(which is >50% bigger than a 2.4m mirror)

Opportunity cost. That budget might have been passed over, and we might not have gotten Hubble at all. We're lucky we got the discount.

Thinking ahead, it's not a bad idea to mix in many smaller budgeted projects, such as the Discovery and New Frontiers programs seek to accomplish.
How do you prevent a hurricane? The coronavirus could have been stopped. The wildlife markets could have been shut down. The spread could have been prevented. The transparency could have been better. I'm not saying China actually does deserve blame, maybe it was way out of control before it was possible to do anything, but this has been a horrible disaster the likes we normally don't see and we need to do what we can to prevent it from ever happening again or if it does to handle it better. Blame is a useful tool, it feels like you're trying to avoid it for unstated reasons when it seems entirely useful in this context.
Yeah, absolutely. There's anecdotes almost for any situation proving a health care to be awful and great. My comment is mostly around the current opioid crisis in the United States of which there's an alarming amount of data to support.

Australia also had, or more likely has quite the crisis too. This is not at all specific to the United States though, I use it as an example as it's demonstratively worse.

In the last few years in Australia, opiates in it's over-the-counter (non-MD prescribed) forms have become controlled and are no longer available over the counter.

I enjoy these retro computing videos. I have fond memories of programming on IBM 360 series systems, DEC, DG, TI and PR1ME systems. I was fortunate that my high school in the 70s had a PDP-8 and an ASR-33 TTY that students could sign up to use.

So much of life is a matter of luck, and I was definitely lucky to be a part of the computer revolution over the course of my career.
If they don't then they certainly should, it sounds like a toxic workplace.

What annoyed me about that slide was the comparison to a pro sports team, which shows how the "ultra-elite" Netflix lacks the critical thinking to see that this comparison doesn't hold.

For one, performance in a pro sports team is quantifiable. So-and-so player scored so many points vs so many tries, whereas the average is so and so. It's relatively easy to plot a normal distribution.

Not quite so easy for software developers. Companies like to say they can measure performance but we all know they can't. Not easy to compare someone who got lucky and worked on greenfield projects with someone who drew the short straw to maintain some legacy code. If the latter struggles, does this say anything about the former? Can you predict the performance had the roles been reversed? No.

So it always falls back to a mix of "how much does your manager likes you" and "how well you can argue you performed". Or if you're at Google then you can add "how well you chose and optimized metrics", regardless of whether you're measuring the right thing.
Since this is a legal question, I did a search of the US Code and found a clue at https://www.law.cornell.edu/cfr/text/42/493.35 :

> "Laboratories that are not at a fixed location, that is, laboratories that move from testing site to testing site, such as mobile units providing laboratory testing"

So in this case, it might be a temporary facility, perhaps in a trailer at a local parking lot, used to monitor cases.
Can we train a neural net to use it's "imagination" to fill in some extra details? Maybe. Would we want to?
Sure, but when you can count the dimples on a golf ball, I'll be impressed. I can't even do that on my HD tv

GUI tools have a very long history of being about to revolutionize the industry but ending up as dead ends. If you want evidence, just look to the past.

I'm honestly all for tools that enable non-programmers to get things done. E.g., Excel, Google Forms, Zapier, and a lot of Salesforce tooling all deliver to some extent on that promise. But there's only so much they can do.

You're right that there's also an elitism problem. But if we're going to get past that, we have to start by understanding what GUI tools are good for. And being honest about their limits.
Try reading AntiFragile. You will be very sick of that word by the time you finish the book.
Better to ask whether the US, as a nation, has the capacity to carefully consider the long-term ramifications of our various choices, and to choose the best option regardless of politics and mob sentiment.

The cries of "if even one person dies, it's too many" ring hollow. We know large numbers will die. The question is how to minimize that number. There is no safety.
It's because of "Not Invented Here" policies. I have seen some banks use 2FA for internal logins - Westpac uses RSA SecurID tokens.
That's covered under my point though, that if you can exchange internationally then why on earth would you bother with Bitcoin? You may as well just hold dollars or gold, you know, things that don't fluctuate 10% in a day and 50% in a couple of years. If you're already doing business abroad then forget Bitcoin.
Looks like a Corbin Sparrow
Same here. Rushed to the hospital after two nights of not sleeping from the back pain and chills at end of Feb. First time I've ever taken an injection for pain relief.
Exactly, use the right tool for the job.

FPGAs and microcontrollers are really good for meeting (and verifying that you're meeting) hard real-time constraints.

Network connectivity (by definition) can't be real-time, so you wouldn't want to run a network stack on the real-time core anyway, even if you could.

Instead of adding another non-real-time microcontroller for networking and making it sweat, go with an application processor and just treat it like a dumb modem that happens to know how to handle VPN traffic without exploding.

There are application processors like the i.MX7 and the STM32MP1 that combine a Cortex-M4 and a Cortex-A7 on the same die for precisely this reason (and similar FPGA fabric + PowerPC / ARM Cortex-A? products from Xilinx and Altera for even longer).
The unusual language that linguists thought couldn’t exist
Not that much more crazy than what you read about other stocks in terms of technical analysis.
It's easy to criticize after the fact. 2 months ago we had very little information on the virus and what we knew said that the virus had the potential to kill a large number of people. The governor made the right move. No one can foretell the future. The best we can do is make the best decision with the information we have.
Babe's in North Texas, several locations near Dallas, has got to be the best fried chicken I've ever had. Easily.

I swear I had one of these too, but it was in December, in Vegas, at the AWS con. (It started thurs or fri, was kinda pissed cause I booked some extra days in town but ended up staying in)

I don't remember all the symptoms, but I remember thinking how weird it felt and that "with a cold or the flu I usually get X"

Not gonna call it covid because I don't have any proof, but a "weird cold" is definitely going around
I haven't used semicolons for at least 5 years. Let's not overstate the "overhead", which I would say is zero. Especially in this comment thread where we just established the tooling handles it for you.

Frankly, I die inside every time I work with a semicolon codebase and have to move a semicolon just to chain onto:

promise
.then()
.catch();
+ .then();

foo
.bar()
.baz();
+ .qux();

You are making the common developer/HNer mistake of overvaluing familiarity and overestimating how hard anything slightly unfamiliar must be.

I challenge you to try it the next time you write some Javascript. Don't use semis and remember the one rule I taught you.
> It would make sense that imbeciles have a harder time bullshitting.

Or your lack of knowledge doesn't hold you back in any way, your BSing is pure nonsense and therefore isn't even approachable.

The best BSers I know are total morons.
Increase production of hand sanitizer, masks, gloves, test kits and other supplies as much as possible. Ensure all medical, food and other essential workers have access now and for the foreseeable future to the supplies they need to perform their jobs safely.

Provide masks and hand sanitizer to every citizen and at a minimum recommend usage at all times outside of the home.

Establish working contract tracing programs, so that spread can be limited.

Once those things have happened (they haven't), re-opening could start to be done safely. Until then, the government's role should be to provide financial, medical and food assistance to the fullest extent possible so that the people and companies who are twiddling their thumbs don't die or go bankrupt while they wait.

The government can literally print money. They could begin distribution tomorrow. They cannot print masks, tests, hand sanitizer, vaccines, gloves, food, etc.
Reminds me of the early 2000s when we were all into BPM, graphical or otherwise. The drawbacks are pretty obvious. I bet the engineers who built it had fun, tho.
A republic is not a system by the which the voter is losing power but one that keeps the government in check as well as the will of the majority against a minority.

It is not a system or an excuse to do things against the voters individual interest.
based on the slides at the beginning of the film, I started thinking the video was censored/redacted when the audio would skip from the film splicing.
Everything you said is wrong. No automaker is open yet. They won’t start opening until May 18th. There are no other auto manufacturers in California. Alameda county is not a hotspot because they shut down early.
Can multi-camera/multi-view photogrammetry defeat this limit and create super-resolution imagery?
I'm 26 and but I look much younger (as long as I shave my beard). I regularly have to show my ID when buying alcohol for instance (which you can do with 16-18 in my country).

It's rather fun for me and I enjoy these kinds of interactions. Can't say it really ever hindered or embarrassed me in any way.

I suspect that if those people who feel embarrassed because they look young were looking older, they'd find something else to be embarrassed about. It's easy to find any number of shortcomings with yourself.
I’d rather have a motorcycle. Motorcycles are faster, cheaper, can carry about the same amount of cargo, and 100 miles on a charge is enough to give me range anxiety.

I’d rather have a car. I often need to carry passengers, carry large or heavy things, and a new economy car is in the same ballpark price.

Who is this really for? I don’t see many people buying this as their only personal transportation if it only travels 100 miles on a charge and can’t take a passenger. It’s price too high and isn’t fun enough to be considered a recreational purchase.
What's the difference between `next build` and `next export`? I couldn't tell from reading your comment.
Optical interferometry has been used to synthesize very large apertures in ground based experiments (e.g., https://en.wikipedia.org/wiki/Palomar_Testbed_Interferometer). That was in the mid 1990s.

Operational ground interferometers have obtained 5 mas resolution, which corresponds to sub-mm resolution from an orbital platform.

You still have atmospheric turbulence, but do we know how to get around the naive diffraction limit.

I’ve seen plenty of elderly people use trains.
I recommend a 32-bit MCU like the Atmel AVR32 instead of 8 bit. The 32-bit ones aren't conceptually any more complicated. In fact, 8-bits adds a lot of complexity in doing arithmetic and updating registers with multiple single-byte writes.

Typical AVR32s give you 32 bits, 33 MHz RISC for $12. That would have been a decent workstation in 1990.
How CommonJS is making your bundles larger
Sibling comments are exactly correct -- we're a library. We don't track or record the activity of our patrons (see e.g. https://archive.org/services/docs/api/views.html#footnote-wh... ), and since most CDNs cannot offer the same guarantee, we can't use them.
If a recipe is too hard to find, just move on. If there's a few paragraphs of things you don't care about before the recipe, press page down. Maybe let Dakota write what she wants on her own site.

One reason I haven't seen mentioned here for that personal content: it's also a question of building context and trust. If I go to Bon Appetit for a recipe, I know they've tested it a few times and it should be more or less OK even if I don't recognize the author. If I go to a barebones anonymous just-the-recipes site, I have no faith that it ever worked and if it did, it wasn't just a fluke and it was written down right.

Having some detail around a recipe from a previously unknown source allows me to build a connection to a persona in my head, genuine or otherwise. If a recipe doesn't work I'll know to avoid the site in the future. If it does work I can remember that connection and come back to the site again with some more confidence.
> With meatspace money

i.e., you cannot fulfil your meatspace needs using cryptocurrency as of yet. It doesn't matter that you are able to isolate your identity online from your meatspace identity.

And this is what gov't can easily enforce - through money laundering laws. If ever cryptocurrency becomes prevalent enough to offer meatspace usage directly, you can bet your bottom dollar that gov't will regulate, and prevent anonymous spending (at least, for any large-ish amounts).
Yeah I definitely wasn't calling for war or anything of the sort.
It's funny you mention FI Calc. We're actually collaborating together to implement my strategy into his calculator. Here's the PR:

https://github.com/jamesplease/fi-calc/pull/197

I totally understand where you're coming from with optimizing for taxes, tax cliffs, etc. Tax law is just so immensely nuanced and fluid. I mean, every state has their own set of crazy rules and these rules change all the time. Even the popular backdoor Roth isn't a sure thing:

https://www.marketwatch.com/story/heres-why-you-may-want-to-...

My calculator takes the Occam's Razor approach to taxes and uses a generic "tax burden" parameter in the assumptions. Someone as savvy as you are would surely be able to keep that parameter lower than others. For most people trying to minimize their tax burden, I think they'd be better served by a financial professional than a calculator. Just my $0.02.
Yes, but the aperture of the interferometer is no longer limited in the same way, so we could say that interferometry gets around the “naive” diffraction limit.
It's not that, it's every 210,000 blocks (approximately every four years).

I guess Satoshi thought that would be a good schedule when the code was written. It must have been hard to see how the future would pan out.
Or terrorism, depending on the perspective.
Can pandemic-induced job uncertainty stimulate automation?
The article says that, as it's technically a motorcycle, it's not subject to the safety testing cars are, "but it has a seatbelt and a rollbar." So possibly no airbag.

Edit: I couldn't find anything on their website about safety at all. I'm guessing that means the safety story isn't something they can brag about. So probably no airbag.
On reddit it’s labeled “other discussions” and it’s an auto created tab. Do you have to do a lot of curation Of the Algolia results? If not, maybe you can make it automatic?
When they mentioned "other settings, unrelated to AdS, in which matter or energy is cooped up within a physical system that has no escape hatches." I thought immediately of the fusion reactor I've been working on.

In my device, an arangement of static fields creates a region in which deuterium energised in a specific reflects back to the center forever and has no outlet even after non-fusion collisions.

The "instability" in my system comes because the extreme stability in the oscillation should cause even a rare event (DD fusion) to happen eventually with 100% probability.
This is a nice article.

I've been incorporating ReadMe.md files in most projects and folders, as well as self documenting Makefiles, with their default target set to help so that it displays something informative about what it will build.

Most of the times I try to include some sort of testing, or alternatively generate index files about the dependencies needed to build.

This has helped me remember the essential parts faster when I revisit projects that haven't been in my mind lately, thus I avoid mis-typing commands and 'forgetting' information.
Suggesting some of the not-so-popular bands that were invited to John Peel's sessions.

If you're into psychedelic, space, stoner rock, shoegaze, noise rock etc, check out Bardo Pond, Bailter Space, Band of Susans, Lush, Loop, Sonic Youth, Spiritualized, Stereolab, The Brian Jonestown Massacre, The Jesus and Mary Chain, The Jesus Lizard, My Bloody Valentine (missing from the list)

Some other interesting bands: Broadcast, Galaxie 500, The Chills.

And of course there were a ton of popular bands worth checking out.
Motorcycles and cars also don't tip over dangerously on curves. That alone relegates trikes to peculiarities that only some will tolerate.
It's harder when you don't make money, and everyone's not downloading the same things.
Almost all US case law has held that any jurisdiction can make anything illegal unless there's a specific higher-ranking (state or federal) law protecting that act from being made illegal.
Why does it have to be introduced in a “meaningful way” to be relevant? If there was at most a single case of it within the U.S. that would show that the disease spread earlier than what is assumed. Again, your argument rests solely on the idea of there must be thousands of death in order for this disease to exist within the states. That is an odd way to think about this.

It’d also be kind of hard to go back and rerun tests for people during those months, which shows why it’s very difficult to pinpoint when this disease started to really spread. I mean, if France and China both had cases during the month of November and December, you’d be hard pressed to say it’s not possible there were similar cases in the U.S albeit undiscovered.
It's sad to see that the media drama around some of the Facebook's practices made some of my friends/colleagues quit Facebook and switch to WeChat.

It's like refusing to eat eggs and milk for ethical purposes and then switching to steaks.
Well, but if you have a bunch of these in orbit, able to image the same site, at the same time...
Who exactly is producing this content?
You can't extract any more information from the image than what the satellite originally acquired - you could make an "error correcting" model that creates an image that appears to have higher fidelity, but the additional detail is just a representation of what the model is filling in based on the other images it has been trained on, rather than an actual increase in resolution.
The reasoning sounds like a facade since it's unlikely that .org registrations and renewals will slow down anytime soon.
promise.catch(console.error) is still handling the error.

Ask HN: Best online course to learn SEO and Content Marketing
Hey HN! Good morning

I run a SaaS business with a global customer base. So far I've been acquiring customers through an app marketplace (eg Shopify, Atlassian, Slack app store).

However, I want to move towards acquiring customers via Google search traffic.

What is the best course you would recommend to me?

I'm looking to learn

- fundamentals of technical SEO
- what should I use for building an SEO optimised website & blog (preferably no-code)
- fundamentals of content SEO
- how to use tools such as Ahrefs to find content ideas and search keywords
- methodologies to generate content ideas

Goal - in 12 months I want to be driving 10k/mo relevant search traffic to my company website and blog.

Sincerely appreciate the suggestions and inputs :)
Well, this donation == lots of saved money. That's probably why NASA comes across as a bit less than grateful.
Not nearly as much as if you're perched on the back of a 600 supersport (and if the pillion does start thrashing around it's far less of an issue since they're a smaller fraction of the overall vehicle weight) but it's still a bit of an acquired skillset.
What's newsworthy isn't the halvening itself but the fact that halvening has completely failed to increase the price.

Yesterday you could buy a coin for a bloated price of 8K.
Today it takes twice as much work to make one but, but guess how much it costs to buy it... Yep, 8K. Until it drops to 4K and then some...

Okay, so now that Bitcoin miners have to work twice as hard for the same amount of electricity, why would they? They wouldn't of course. Transaction fees are up in recent months, around $1 on average, which is good for the miners but doesn't exactly happen BTCs find any use.

BTC is well past its prime.

PS4 Homebrew Toolchain
If they’re using pure MD5 such that collisions work, then using steganography techniques to embed random bytes encrypted with some obvious cipher will bypass the initial autocensor while simultaneously driving the Chinese intelligence services crazy trying to decrypt the random bytes in every image sent. Note that using this approach may cause threat of harm to any sender or recipient within China’s sphere of influence.
