Back in the 20th century, I might have said the same thing when I was enamored with Larry Niven’s hard sci-fi. Nowadays, I find it hard to entertain the possibility of civilizations much more advanced than our own: the persistently dismal news and noticeable slowdown in materials-science technological innovation since the turn of the millennium, makes me suspect that races inevitably hit the Great Filter around the point where we are now.

After all, hasn’t it been noted that science-fiction is no longer as optimistic about technological progress as it used to be?
Very good point. Additionally, with insert and delete we might need to apply the rules of broadcasting [0].

For example, if I have a 2-dimensional array and I insert a scalar value by using axis=0, the scalar value needs to be broadcasted to match the column dimension of the array:

>>> a = np.array([[1,2],[3,4],[5,6]])
>>> np.insert(a, 1, 11, axis=0)
array([[ 1, 2],
[11, 11],
[ 3, 4],
[ 5, 6]])

"Iron deficiency isn't an issue, probably because there's lots of enriched foods, so let's stop enriching food!"

I think regulatory analysis requires a little more thought than that.

That's a Julia thing, not a Pluto thing. Not a fan personally but I think that's a minority opinion in the Julia community.
Portability was a long desired attribute of computer software up until it turns out that it doesn't matter at all.

When software was deployed on floppy disks and there were 10k architectures going around, portability was critical to expand the market reach of any distributed software.

But in the modern age when the software runs "in the cloud" and there are dominant platforms out there, turns out that portability doesn't matter - nobody is changing platforms when they don't need to.

So this makes this achievement a pretty cool demo without any industry impact, since people don't distribute C binaries anymore.

The idea behind it and the technology developed is pretty cool :)
+1 - delta v is what matters, and a regular explosive would not throw a satellite off orbit significantly.

But this makes me wonder - what is the minimum possible size for a nuke? I wonder if say 1-2kg nuke would be enough to throw all the debris out of orbit...
Is there some remote possibility it damages the CCD or optics?
this is pretty good!
Space is big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's a long way down the road to the chemist's, but that's just peanuts to space.
it would be easier to have it spiral into the atmosphere and burn up

i mean thats what happens to most satellites anyway

I'm glad it's not that easy... I can see the "pranks gone wrong", the "ex-boy friend revenge" and the "shave-your-kid facebook 6-month trend" potential of this..
Probably GDPR concerns will be raised since they'll effectively be storing PII.
Even without that argument, the behaviour is still consistent with other cases for arrays in JS anyway.

It’s strange but I don’t really feel bored at all (I don’t have kids). In fact work-wise not a lot has changed except for having no commute, and since my commute was pretty short, the increase in time is quite marginal.

Iran initiates human trial of COVID19 vaccine today
I dug deep for this lol... It looks like somebody ballparked it from a graph, I read it in a news story I can't find. It looks like COVID incidence among study participants comes to a screeching halt somewhere around 8-12 days after first dose

Page 30 of
https://www.fda.gov/media/144245/download

See this graph
> Cumulative Incidence Curves for the First COVID-19 Occurrence After Dose 1, Dose 1

Also keep in mind this graph is probably based on COVID diagnosis date. Since it's unrealistic to test positive the day you contract COVID, I think it's reasonable to say it might even be effective from day 3-5 on
Lilbits: Game Boy's long lost WorkBoy accessory revealed at last
I don’t think you can just proactively request one, but that providers will notify you as soon as you are eligible and they have it available.

My PCP and the hospital they’re at already knows my date of birth and my medical history. I haven’t been told I can get it yet because, well, I can’t get it yet.
It doesn't. What matters is that you have a filesystem that can detect and repair bitrot. For that to work, it needs to check everything occasionally, which means they need to be powered up occasionally.

If you don't do that, eventually you'll get to a point where it can't repair anything, and then you gain nothing over using a filesystem that doesn't do this, is the point.
Patents will survive their retirement ;-)

I assume RISC-V appeal is because it's open and thus allows people to explore (proprietary) implementations while maintaining compatibility at the ISA level.

If I understand correctly you cannot do this with Mill either.

Their work looks very interesting, but I'm not drawn in writing an fpga implementation or work on a toolchain for it, since I know any success may be impeded by patents
Reasons FinTech will gain major investment in 2021
I moved to splitting my bashrc into multiple files and having my main bashrc source them from a ~/.bashrcd directory.

At heart it's a short snippet that just checks for existence and sources each file in the directory:

https://github.com/targaryen/bashrcd/blob/master/install/ins...

I added aliases to list/edit/remove entries from the .bashrcd directory and resource it. And a script I can call with a one-liner to edit bashrc on a new machine to add the sourcing and the helper aliases.

It'll load alphabetically so I can prefix entries with a number to specify load order (defaulting to 0100 so I don't need to specify this in the commands unless I explicitly changed them).

So the end result is that I can quickly edit or create a new bashrc entry by running 'ebrc entryname'. This opens ~/.bashrcd/0100--entryname in vi, and when it's saved it'll re-source so the add/change takes effect immediately.

Or 'lbrc' to list contents of the directory, or 'rbrc entryname' to remove ~/.bashrcd/0100--entryname

It's fairly simplistic but takes away most of the cognitive load of managing a complex bashrc.
So, this does nothing to actually combat space junk in the sense of debris in orbit. The actual goal is:

> We are very concerned with the fact that all the satellites which re-enter the Earth's atmosphere burn and create tiny alumina particles which will float in the upper atmosphere for many years
I ordered a few by accident from AliExpress and they showed up yesterday. I don't know for the life of me what to do with them. I was thinking maybe as a temperature/humidity monitor thing, but it would have to be mains powered because I don't think there's a way to make a device like this diy'able (with arduino and dht22 level components) and make it run off a battery for more than a few months. So any suggestions are good.
Why do LTO manufacturers always quote compressed sizes, like we’re in the days of stacker?
FCC does. Had to do deconfliction between JTIDS data links (could use more more than X of the available timeslots between all military datalink users) and S-band radar. They’d monitor us and actually occasionally issue fines to units that messed up their terminal’s time slot allocation.

What has made Divatrim Keto so useful for people?
Divatrim Keto is advertised on-line as the strongest raspberry ketone product you could look for online based on the simple fact that its formulation is different. It is known to contain an top amount of raspberry and acai berry to help people stop excess fat fairly quickly.All of those are stunning assertions when bearing in mind all the other ketone dependent weight loss supplements nowadays it could be bewildering concerning what kind to select. The good thing is as soon as you surface looking over this document, you will be able to produce a well informed verdict.

No matter how you explode it, turning one piece of debris into many pieces at even higher velocities is only making things worse.
A trip down memory lane for sure! I can't help but feel that a list for 2020 has to include the Macbooks with the M1 chip. Personally, the difference between my mid-2017 Macbook Pro and my M1 Macbook Air has been astronomical. The battery life alone will "save" Apple.
You're right with Tinypass - it didn't work out. Piano's model is a bit more financially viable for the type of customers it is targeting.
Afaik Apple doesn't use Gallium Nitrate for their chargers and a recent report by Mac Rumors confirms my assumption, but at least they're planning to release such a product in the future: https://www.macrumors.com/2020/02/20/apple-could-launch-gan-...

Considering how small my cheap 65W GaN charger is, I would have been disappointed in Apple engineering if theirs were still as heavy and big as they are.
Audio shouldn't be difficult though. There were even a few laptops in the past that did it sort-of-okay.

The trick is to have a bunch of microphones along the edge of the display, all the way around. This then enables beam-steering and noise filtering by keeping only the signal common to all microphones.

Mobile phones often do this kind of thing, but PC developers are stuck in this local minimum that they seem completely unable to escape.

Speaking of which, the iPhone 12 Pro has a HDR OLED display that goes toe-to-toe with a USD $35K Sony BVM-X300 Master Monitor: https://www.youtube.com/watch?v=n_czpXW3yKE

Meanwhile... good luck finding a decent 17" laptop with an OLED screen!

As far as I can tell, all OLED laptops made in 2020 used the exact same Samsung 15.6" panels, and then all other OLED manufacturers also simultaneously agreed that no sizes above that need exist:

https://www.oled-info.com/here-come-oled-laptops-sdc-start-p...

https://www.oled-info.com/boe-demonstrates-new-oleds-monitor...

Keep in mind that Samsung makes an OLED panel for Apple that is capable of 1,200 nits peak HDR brightness, but is incapable of making a laptop screen that exceeds 400 nits for some mysterious reason. I can't prove, but strongly suspect that all PC parts are now being made in the supplier's legacy plants, and the top-tier stuff is exclusively reserved for mobile device manufacturers...
How to Transition to an Outsourced Team
How do you transition to an outsourced software development team? You might be looking to make room for your in-house developers to start on a new project - but still need to maintain your existing software. You could be questioning the extra costs of having employees working from home or other scenarios. We cover the fairly simple process for outsourcing in each of these scenarios and other factors you’ll need to consider.

I kept a Japanese Peace Lily on my bathroom windowsill in Scotland for a few years. Never watered it once. It thrived, and survived entirely on shower-steam (presumably condensing on the leaves/pot/soil).

They're pretty resilient plants to keep, the way the leaves start to droop when they need watering makes it really easy to take care of them, even for people without particular plant-skills.
That was it, all fixed now. Thanks for the suggestion :)

As long as its GDPR compliant...

Seriously though, "vaccination is not mandatory but we keep a registry and we share it with partners, and it will have awesome data protection" sounds problematic - even if it were true that data protection is awesome, and even if there was a legal basis - what is shared, what is the data used for? Who is going to be considered a legitimate "partner"?

I doubt politicians' capacity - worldwide - to ask the right questions and find good agreements.
The country public services already have all the PII and in case od public health and safety they can easily justify such regiastry
It's not just the Internet, it's the entire planet turning to questionable methods and high risk investments in a desperate bid for income (which I also attribute the recent Bitcoin pump to).
Hi theaussiestew,

I did it by hand. The hardest part was finding a way to create the sentence similarity matrix in a fast way. I solved that problem by creating a Matrix class around Javascript's typed arrays.

For the complete picture, the app itself is written in Angular because I'm familiar with it (probably overkill, really) and I'm using Mozilla's pdf.js [1] to render documents.

I blame ubiquitous access to cars and phones as significant early contributors to this problem, with modern IMs and social media being the final nail in the coffin. Because together, these technologies enable your social network to be mostly independent of location. Nowadays, when you move to a different neighbourhood or a different town, you'll still be in daily contact with your friends and family from the previous location, and (if they're relatively close by car) you'll also hang out with them regularly. So you have no reason to try and meet new people at the place you now live in, because you still have your old social network! Hell, new friends will be competing for attention with your old friends - where just few decades ago, these old friendships would go to "hibernation mode" by virtue of distance.

Internet communication, with its much richer modes of communication, is essentially social junk food. It's not a real substitute for meatspace interactions, but it satiates the hunger for socialization. Thus people feel ever more connected and ever more lonely at the same time - loneliness being social malnourishment.
This is the simplest way of doing it and in my opinion the best. You can just have all of the files where they are supposed to be without the need of symlinks or anything. I've been doing it this way (well a bit different but very similar) and it works like a charm.

I explain here the steps of how I do it:

I'm very excited for hologram tech, from AR (Magic Leap, Hololens) to more "in-world" like voxon and looking glass[0]. It's great to see progress and competition in the space.

William Hearst's relationship with Anslinger (as well as the latter's racist views) and his financial interests in lumber are well documented.

It's not about wanting to spend more money, it's about wanting to spend just enough money to keep competitors from springing up, which is what really keeps profits high within an industry. Hemp's behavior as a weed would have allowed very low capital cost upstarts at a time when industrialization was eating everything in its path and creating natural barriers to entry.
I'm struggling to see what this new measure is actually telling us that's useful. We know bond yeilds are super low, whcih is putting pressure on people to move into more risky investments like the S&P. This measure seems to simply show that pressure. What it says nothing about is whether those investments are good. What it seems to show is that there's enormous pressure on the stock market to go up. At some point though, those companies have to actually make money. We know they're not going to be making hugely higher earnings - we're a long way into a good economy, there's no real reason to think everything is going to get massively better. The only alternative is that inflation sky rockets and that's how earnings go up.

So what happens if inflation goes up? Well for inflation to have any meaningful effect it would have to blast past the fed's targets and the fed would need to massively increase bond yields. Which would remove the pressure on stocks, causing stock prices to drop.

What I'm not so sure about is what happens if inflation really does stay flat. If inflation stays flat, then everyone is just holding a load of stock with really bad yeild. Does that also cause a crash when people realise they're holding bad investments and those bonds don't look so bad because there isn't inflation?

Hello,
I would like to learn about the Big O Notation and I am looking for good resources. Unfortunately I can not find anything better than few minutes long videos on Youtube.
Could you please recommend me something?
Thank you
You're making a big accusation / conspiracy theory: that the proponents of "population bomb" arguments were also domestically anti-abortion and womens rights to increase the number of births in the West and decrease it in Asia (and presumably, Africa) due to reasons of race and racism.

Such a comment needs a lot more supporting evidence to be considered anything but an outlandish conspiracy theory.
I think you underestimate the demand. Your sample size is small and contains an abnormally large percentage of people that have already had covid so that will skew things.

I haven't had covid and would like to get vaccinated as soon as I can. Many, but not all, people I know feel the same way.
I work for an automotive manufacturer that has a model that couldn’t be sold in the United States due to its lack of a steering column airbag (probably along with other items).

Unfortunately, just as a matter of historical accuracy, this is secondhand information, and both of the hands are unreliable. There's no real proof Ehrlichman said this (it was claimed by a journalist many years after his death), and Ehrlichman was a known liar who was convicted of perjury, so he's a non-credible source in the first place.

Have a look at proper courses. For example https://ocw.mit.edu/courses/find-by-topic/#cat=engineering&s... should have it. Check the "Introduction to Algorithms" ones.
And that's assuming we want to play/make games with "realistic" simulations! I'm sure we've all played those sandbox physics games where a few values were tweaked just to far in one direction. Sometimes that can be really fun! I'd e interested to know if these more advanced tools take that into account, or will there be frequent cases of needing to roll your own physics engine?

I'm trying to think of an example, but I believe I remember reading about a game that purposefully used a slightly lighter gravity for some models to help the player feel more powerful (?) than other characters. I wish I could remember, but the idea is the same. Physics that are dynamic could be a fun/useful gameplay mechanic and I hope we don't see those types of games go away because everyone decides it's too complicated/not worth it to use a different physics algorithm than the one shipped in some console SDK.
On the other hand the virus has turned life upside down for virtually everyone. I understand choice but not getting vaccinated affects everyone else.

So it's not as easy, especially since everyone wants to go to school, fly, shop and can infect others.
Using batteries like this sounds extremely wasteful. A lot of energy goes into extracting the lithium and it's not like they last forever.

HDDs are fine for short term storage, but they are too unreliable when you want to keep the data for many years, possibly for a lifetime.

Unfortunately, currently there is no other commercially available method of archival storage, except magnetic tapes. Optical storage has a too low density to be able to compete with magnetic tapes.
