>Your confidence in coinbase, given they are unregulated in any meaningful way, is IMO misplaced.

I think you're reading too much into my comment. I wasn't trying to claim that cryptocurrency exchanges didn't engage in shady behavior, I was only claiming that the specific accusation of "they halted trading because of liquidity issues from their pumping" didn't make any sense.
Many progress bars are implicitly segmented; it's just that segments are determined by the programmer and never exposed to the user.
I just don’t think it matters enough to warrant the effort. Say you do architect the system capable of rendering the perfect loading bar, because it just has to be a systemic solution... what did we really solve here? It still takes 10 seconds to do the operation, there is just better incremental progress? Decent incremental progress is basically the same as perfect incremental progress IMO

This competition doesn’t predict markets. It’s a manufactured game to resemble things JS does. And even if it were an accurate representation, the competition is run on 128 unknown features that you would have to discover for yourself. And trust me, >90% of the work is identifying the features.
>On the other hand, the ribosome is an amazingly complex machine

Just a bit:

Transcription - https://www.youtube.com/watch?v=SMtWvDbfHLo

Translation - https://www.youtube.com/watch?v=TfYf_rPWUdY

Replication - https://www.youtube.com/watch?v=I9ArIJWYZHI

It's not clear to me how much these features can be degraded without destroying the ability for organisms to reproduce with heritable traits.

Also, when listening to these videos, ask yourself 'how' and 'why' any time an action is described. For example, the following parenthetical questions from a small chunk of the 'Translation' video:

"The addition of each amino acid is a three-step cycle; (Why three step?)

First the tRNA enters the ribosome at the A-Site (Why does it only enter at the A-Site? How are other options prevented and/or made inconsequential? Was it always this way? How did the features of the A-Site evolve for this to happen. What happened before this? ), and is tested for a codon / anti-codon match with the mRNA. (How is the tRNA tested? What happens when it fails the test or is missing the amino acid? What is the energy budget of this test and what are the specific features of the ribosome, RNA, tRNA and amino acid that make it possible? What happened before this testing was done? How did we get from the lack of ability to test and the ability to test?)

Next, provided there is a correct match, the tRNA is shifted to the P-Site (What is the mechanism of this shifting? Why does it only go one direction? What is the energy budget of this process and how is it powered? How do we prevent multiple tRNA from shifting or keep it from shifting more than one spot? What occurred before the ribosome/RNA/tRNA/amino-acid had the features to allow this to occur?)"

You get the idea.
100% this. Anonymised features remove any hint of lateral thinking that is the essence of science, and just focuses on the pure numbers. This is dangerous. One of my data scientists once ran up a $2000 bill on training a CNN on what was essentially a speed = distance/time calculation, and was really proud when he got 92% accuracy. A real facepalm moment.
Why does there need to be a point. It's an essay about a historical figure.
I remember a Windows 95 progress bar telling me that a file copy would take quite a while. From memory, something like 10^10 seconds. For a few MB.

I upgraded from a 32gb x86 machine to the 8gb macbook pro and it's downright amazing and I saved a bunch of money in the process.

Apple is going to make an absolute killing on people upgrading RAM unnecessarily.
When I used to work in ad agency land, there was typically a role called the "traffic manager", which was sort of like a project manager but for the whole creative department rather than just an individual project or two. They would definitely organise everyone's calendars for them, amongst many other things. It wasn't a job I was terribly envious of, I must say!
I know very little, so perhaps someone could enlighten me. But I am curious how Apple Silicon will be for machine learning.

When Apple releases a MacBook Pro with 64GB of unified memory (assuming they will) — won’t that be amazing for machine learning? I am under the impression that GPU memory is a huge factor in performance. Also, is there any way that the neural engine can accelerate training — or is it just for executing trained models faster?
My guess:

1. "weak" memory ordering (atomic Aquire/Release loads/stores)

2. low memory latencies between cache and system memory (so dirty pages in caches are faster updated etc.)

3. potential a coherency impl. optimized for this kind of atomic access (purely speculative: e.g. maybe sometimes updating less then a page in a cache when detecting certain atomic operations which changed a page or maybe wrt. the window marked for exclusive access in context of ll/sc-operations and similar)

Given that it's common for a object to stay in the same thread I'm not sure how much 2. matters for this point (but it does matters for general perf.). But I guess there is a lot in 3. where especially with low latency ram you might be able to improve performance for this cases.

I think his point, though not well made, is that it’s likely parent is not the first to ask this question and that the researchers have likely already thought about that.
My wife worked in a GroupWise shop in the early 2000's and apparently there was tracking-related political intrigue and drama. >sigh<
Yea, I've been using VSCode these past couple of weeks as I'm now coding in Python + JS after a few years of only JS with WebStorm... and I'm buying a PyCharm license tomorrow.

VSCode is fantastic in many ways, and I'll keep using for my markdown dev notes and for general purpose programming occasionally, but for anything of substance I'm a JetBrains convert.
If only we could get NeXT back... or Apple would build something as well designed, clean and productive. Give us a proper streamlined UI, not this over-spaced baby blur and give us proper APIs for everything. Security is good, but it needs to be handled in a more consistent way, with less trouble for developers.
Why don’t you take care of your son?
"no matter what" as in of course there will be limitations to how much a manufacturer can output but there will always be some supply further down the line.
I guess the good thing for those of us who can't afford a new mac right now is that the used market will be flooded with recent models at a cheap price LOL.
People don't want to watch the credits, so netflix doesn't show them and/or makes them easy to skip. Want proof? Next time you're in a cinema watch how many people walk out as soon as the credits roll, most people want to get out as quickly as possible.
I know I'm late to this, but it turns out they do collect US sales tax. Not sure about the others like taobao or dhgate, etc.
Just to present another point of view (from my subjective experience). Yes it is possible to be productive on the linux desktop.

I'm using Fedora 33 on my personal laptop with nvidia drivers. And never needed to install any drivers for my work laptop.

Upgraded both laptops 3 times from Fedora 30 without a hitch.

And it's a one step process using a graphical interface [1].

What I'm saying is that (in my own experience), linux of today is very different from linux of 10 or 20 years ago. I've had my share of problems before, installing drivers for graphic cards and modems back in the "00"s but I think that most linux distros have come a long way since then.

Linux may not be the best choice "getting stuff done" for an average user. But, from my own experience, for a software developer it's a good choice. And in the company I work for, most developers have hp elitebooks with fedora installed. (I'm picking software developers for the comparison because they represent a significant portion of macbook pro users).

The consumers buy part, yes, if the only reason they need it is because software has become stupidly inefficient. All of this e-waste is not good for the planet, and manufacturing is a significant contributor to global warming.

If consumers are replacing their computers to do things they couldn't do ten years ago, then great, that's a good use of resources!

If consumers are replacing their computers because today's IM clients are 10x slower than the perfectly good clients we had ten years ago, that's a problem!
Who was the counterparty? Margin trading implies that some party in addition to the customer is at risk. Some of the Bitcoin exchanges tried to escape this by closing out positions when the customer's equity was wiped out, but in a falling market, you often can't do that fast enough. Then the broker/exchange has to collect from the customer beyond what they had in their account.

That led to messes like this [1] when the bottom fell out of natural gas prices.

Every 8gb mac I’ve used before was fine, and that was with running Xcode, Firefox, photoshop, mail, terminal, and other programs.
As superoptimizer research papers go, this is pretty ancient and very far behind the state-of-the-art. The paper describing STOKE (https://theory.stanford.edu/~aiken/publications/papers/asplo...) is what I would recommend as the starting point instead.
That sounds great, I like Espurna for the web interface and general quality but I really hate the C-style header file configuration, it's very hard to update your code.

With YAML, I at least know that the file I have will continue to work across updates. Seems much more usable.

You're bringing up the easiest use case though. Most complex flows cannot be easily expressed by a single determinable metric.

To answer your question: Yes. The volatility is a trader's dream.

That's insane on so many levels. I can sorta respect it though - like someone wanted this and made it happen.
The road is Lockhart Basin Road, well-known among Utah off-roaders. I've been there, and also camped on one of the fingers of Hatch Point, directly above the monolith.

I'm curious about the Neural Engine cores. What software use this? Why would I want to buy a Neural Network coprocessor in my machine, instead of using that money for a better cpu/ram/ssd?
I wouldn't expect it to be particularly competitive in training large models. It's an integrated GPU with 8 cores, and the "neural engine" has an additional 16 cores. The kinds of discrete GPUs (mostly Nvidia) that people use for deep learning have more like 5000+ cores.

I think Apple is aiming more at either training small models, or running pre-trained models. For example Photoshop is starting to integrate neural filters, so NN inference performance can be important for some desktop applications.
Chess is just a convoluted version of TicTacToe. The longstanding idea that it's somehow representative of human intellect is ridiculous.
Except this specific one isn't. It's the blog they use for announcements, not the network.
On intel atomically increnting a counter is always sequentially consistent. ARM might get away with weaker barriers.
That clarifies things perfectly, thanks. As long as the wire format is compatible (which it is, from your description), then compatibility is only a matter of software updates, which is great.
There's absolutely no way that can reflect reality. I don't even think it's possible for people to downgrade their speeds that much even if they wanted to.

Anecdotal, but I just checked and the slowest speed I can get for my Stockholm apartment is 250/250, and the slowest speed my dad can get for his apartment is 100/100.

This has got to be some data anomaly. If they're basing their numbers off of tests that people voluntarily do, then maybe in 2019 a lot of people tested their mobile internet, while no-one bothered testing their home internet because it's fast enough?
No, cryptsy.
Yeah, both this and the original question are good points. I wonder what the paper itself has to say.

The early bits are pretty readable so far [0], but I doubt it calls the original question out quite as succinctly as it was asked. Lots to mull over though!

The quote right after explains your concerns.

>The memory bandwidth on the new Macs is impressive. Benchmarks peg it at around 60GB/sec–about 3x faster than a 16” MBP. Since the M1 CPU only has 16GB of RAM, it can replace the entire contents of RAM 4 times every second. Think about that…
Plastic recycling is mostly B.S., it's difficult and so energy intensive that it's usually better for the environment to landfill the old plastic and make new stuff. Metal and paper recycling is very environmentally sound though.

That would depend on the APIs and language you use, of course; some of them might do buffering or copying differently.
With all due respect, I think you have read something I did not intend in this comment. Abortion is not necessarily genocide, but Iceland's specific application of it to those with Down's Syndrome is the textbook definition of eugenics.

I can clearly see how an unqualified "abortion is genocide" would be an unrelated controversy, but within the context, my point was to illustrate that a naive understanding of science as something that consumes data and produces a better society is also scientific illiteracy.

I probably should get a new router. It's sort of become low priority.

The main signal issue is that our router is in the garage next to where our internet comes in.

For a few weeks in the spring I was looking at setting up a wired network since all the phone jacks in our house are actually Cat5e cable that could be upgraded to ethernet jacks pretty easily.

But then I also lost ambition for that idea.

I did spend $20 a couple months ago to get a latest-generation wifi chip for my laptop, which I'd recommend to anyone since it's a trivial thing to upgrade and I never even realized the wifi chips were swapable. That improved my network speed by a factor of two I think.
> The Web was happenin’ (invented as you may recall on a NeXT workstation) and we lost

This is true but not entirely.

I have recently for no productive reason become interested in computers built by different nations early in in the computer revolutions.

There was so much competition, so many ideas, so many opperunties.

Anyways I live in Norway now and Norway had a company called Norsk Data that I had never heard of until about a year ago.

They designed their own hardware, and operating system.
For a while they made a "super computer"

Some highlights:
The NORD-5, the world's first 32-bit minicomputer - beating the VAX, often claimed to be first - by 6 years

ND-570/CX, was at the time it was released 32-bit supermini ads i 1983, 7.1 Whetstone MIPS

Their greatest claim to fame aside from what listed above but closely related, they delivered the computers for the CERN
colder back when that was starting up.

They also delivered computers to help create F16 flight simulators.

For a short period of time Norway had best in class computers. I had no idea.

To the relevant part, sorry about the long wait

Norsk Data claims:
"
The World Wide Web originated when Tim Berners-Lee wrote the ENQUIRE program in Pascal on a Norsk Data NORD-10 running under SINTRAN III at CERN.[4] They also used ND-NOTIS, that was based on SGML, and emailed with NOTIS-MAIL, using tcp/ip, coded in HTML.
"

It is partially backed up by
https://www.w3.org/People/Raggett/book4/ch02.html#:~:text=19....

I have only seen ND machines in the museum and on the web.
I wasn't around at the time so its based on Norwegian documents
for the most part.

I do know that there were Nord server used in the Norwegian military up until at least 1995. The ginormous task of creating the replacement system took a very very long time

The very early origins of Norsk Data was at FFI, a defence research agency. (Kinda like (D)Arpa)
I really wish managed airflow instances were cheaper for smaller companies. I built my own using spot instances and it's so affordable compared to astronomer and the others.

So far it's been very low maintenance - outside of the few random scares where dag logs filled up my server - but then I researched and found maintenance Dags that prevent a lot of issues.

Wondering when my next outage will be is always fun, but it's been pretty stable so far.

E: I know and appreciate the tech they put into it. It's just too high of a price for me once I get the workers added. I still want migrate mine to fargate workers at some point though.
The "reinvention" is primarily in the client (but also in the client service) and has to do with getting you to use email differently by having you emails behave in a non-traditional manner.

Haha! I don't mean to imply that I've uncovered some fatal weakness (or even necessarily a weakness at all)! That's just the question that jumped to mind when I read their paper, and I figured someone else might know the answer.
I sure do want to trust my computer to a few elastic bands holding it to the underside of a desk! Sign me right up. I see no problems with this plan whatsoever.

The keyboard integrated into the desk is a beautiful piece of form over function, I'm sure it will be fun to pretend you're the head of Encom until you want to shift your weight and you try to shove the keyboard over a little bit to make your wrists happy.
> Maybe a better question is: why are there so many more men than women on dating services?

One answer can be found in census data. The number of childless male adults is almost twice of that of female adults, but the desire to have children has been found to be identical among women and men.
The premise was

> addition operations of numbers with log(n) bits deemed to take O(1) time.

not

> addition operations of numbers with n bits deemed to take O(1) time.
How would that work? The refcount need to be on the pointee, not on the pointer.
Recently I started using Typora(https://typora.io/). It not native, but its performance is decent.
Yeah, I meant that Jane Street aren't doing this to find a solution that'll improve their own tech.

I expect in a constrained environment, someone on Kaggle will beat Jane Street's solution.
An example of this in action is Hinge. They require users to include height in their bios (and always show it on profiles), but don't have a field for weight.
Not enough anymore. Now you have to jiggle and click. And the clicks can't be random. They have to be on UI elements every so often.
Reference counting releases memory as soon as it gets dereferenced, while GC cleans up memory periodically, which means higher memory usage (more than what's actually in use at any moment).
I still do not see how any of these things are a poll tax. A poll tax is something that inhibits your right to vote by charging you money. For example, requiring a government-issued ID may be construed as a poll tax.

Are you arguing that regulations and taxes on guns and accessories are LIKE a poll tax because they inhibit exercising your interpretation of the 2nd amendment? If that is the case, I would argue that it is different as the 24th amendment specifically outlaws poll taxes and there is no similar law or amendment around firearm accessories.
Kraken is destroying them in margin/derivatives and their margin product is quite bad. Not saying there is a relationship, but it is a good trade for Coinbase if Kraken has to shutter theirs as well.
It is a lot of atomic +1 and -1, meaning possible thread contention, meaning that no matter how many cores your hardware has you have a worst case scenario where all your atomic reference counted objects have to be serialized, slowing everything down. I do not know how ObjectiveC/Swift deals with this normally, but making that operation as fast as possible on the hardware can have huge implications in real life, as evidenced by the new Macs.
> I want macOS that has a UI of Windows 95. That would be totally insane on Apple Silicon.

So much this. I used to run Windows 7 in classic mode and really liked the low footprint, no nonsense appearance. Windows 10 has no such mode.

Neat idea, but how expensive are these?

I just use a drill or staple gun, and lots of zap straps. Everything goes to exactly where I want it. You can buy grommets pretty cheap if you need a hole. I find myself making adjustments a few times a year, when I upgrade or replace hardware. Yes, it takes a bit of up-front work, but the result is great. This approach has worked just fine for me for 15+ years.

>I just got one. I’m blown away by the speed as well. Chrome runs insanely fast!

I've got a 5ish year old desktop and Chrome runs, afaict, pretty much instantaneously. At least I don't notice a perceptible delay. I'd be interested to see a side by side comparison of page renders on M1 vs an older laptop.
In my experience, technologists in general and engineers in particular are grindingly naive about social system design. If it says "Hate speech" on the tin, it must be bad, right? Look, it says "hate speech" right there. Must be pretty hateful. Let's ban it.
