I have a fit band that vibrates every one hour if I have been sitting for as long.

I make it a point to get up and walk around. Take my eyes off the screen.

Since the pandemic forced me to work from home, I take this hourly opportunity to get in 30-50 pushups every hour. Also helps with water intake. And takes my mind off the urge to take a tea or coffee break. But now that I think of it, I could've done the same in office.

Having flux installed also helps.

You need to reduce the time you are looking at the screen continuously. Realising that has helped me lot.

Also washing your eyes with water, 3-4 times a day helps. Makes eyes relax.

Hope this helps, cheers.
I agree if you add the clarifying statement ...not an AMD/Intel killer for __some__ compute-heavy workflows...

It’s clear there are other workflows which some people characterize as “compute-heavy” where the M1 is superior.
I don’t think it’s them, I think it’s the people at r/plex that are using google drive as their data store and people bragging about having 100s of tbs of content.
SIMD and ie Nvidia WARP are not the same. Idk about Apple’s GPU, but for example there is no GPU alternative to the SQRTPD instruction (Square root of double precision). Also, when there is branch divergence across threads, CPUs still do a much better job than GPUs.

Curious to think about how unified memory may change the ratio of flops/memory access when it makes sense to shift job from CPU (better for low number) to GPU (better for high ratio)
> I’d be curious how the unified memory architecture shifts the cost dynamic for GPU acceleration.

Correct me if I'm wrong, but is this actually different from regular integrated graphics that have been in intel and amd chips for decades? I remember there being some initiatives from amd proposing similar offloading under the name HSA almost a decade ago.
I don't think there are actually any software really using it.

These instructions can be beneficial when leveraged providing significant speed ups for larger transfers.
I maintain hub-ctl on GitHub. It's cool to see someone expanding on this work. You've got a great list of working hubs as well.

Right. Semiconductor-grade silicon is way more valuable than silver, and some types of semiconductors are, I believe, even more expensive than gold.

But you have to buy them. You can't buy things with them.

You might be able to barter, if you can find someone who has what you want, and also happens to need some 6 9's pure gallium indium phosphide or whatever.

However, the guy at the corner liquor store is unlikely to give you a bottle of whiskey in exchange for it.
He was very clear in what he was trying to do. Just because it didn't work doesn't mean he didn't try.

> It's hard to argue that tariffs on goods from China don't make it less attractive to buy goods from China.

It's true that tariffs will make buying goods from China less appealing, but if you look at the outcome, it's not really a win. Consumers are paying more for the same goods, companies are scrambling to move their production to India and Malaysia, and there's not a significant increase in US manufacturing.

A properly executed initiative to increase US-based manufacturing would address all of the factors necessary to restart manufacturing:

- Not only tax cuts, but subsidies and investment aimed at increasing manufacturing in specific industries

- A concerted program to identify labor and skills shortages, and address them

- A program to identify the missing parts of manufacturing ecosystems and address them. One reason why electronics are made in China is not only cheap labor, but access to a whole ecosystem of suppliers and other manufacturers. Need one million PCBs assembled, plastic casings made, half a million cardboard boxes printed, instruction manuals printed and bound, well, there's a whole ecosystem of partners ready to get all of these things done with the capacity to have a relatively short turnaround time.

- A clear bipartisan commitment that this is something that won't get deprioritized or axed one or two administrations later, but something that is of national interest and that both parties agree to push forward

- A national focus on a key differentiator from other countries' manufacturing. China has cheap, Japan, Switzerland, and Germany have good, the US has big and sturdy maybe?

- Tariffs to protect newly formed manufacturing businesses, but only in conjunction with all of the above

This is what a solid plan for restarting US manufacturing would look like.

FBI crime stats are a great source. For example, of murders in 2019, "Black or African American" accounted for 51% of murderers of known race (despite just 13.4% of the general population being black).

tl;dr: Hyperbeam is roughly a netcat tunnel that connects via a DHT topic instead of network address; use it where you want a secure one-off tunnel. (for example, to transfer a key for Wireguard)

Wireguard:

+ Can tunnel arbitrary IP traffic

~ Has stricter encryption, with full asymmetric keys (and optionally adding a symmetric key)

- requires permissions to load a kernel module and configure the network stack

Hyperbeam:

+ Only needs userland UDP sockets, not a kernel module

~ Derives its keys from a passphrase, so does not require transferring a full cryptographic key between devices

- is a single application-layer pipe, applicable in shell workflows but not transparently tunneling arbitrary applications
Before spending the rest of the day reading articles on this site, I have to say this is a comprehensive and easily understood history for how the U.S. got to this point financially.

Being a cynic, I've studied many aspects of this system for some time. I have to say I'm shocked how obvious the PR has been for some of this stuff.

A favorite example is the Iraq war. Clearly a mafioso protection racket type of move. Nice country you got here, quit using Dollars and see what happens...

The 1970s in can be almost explained in the sense of a 1930s style run on the bank, except this time it's allies and foreign countries after their gold.
The Saudi benefit from attacking Iraq probably even mirrored what France thought it was getting in "French Indonesia and French Vietnam". You can almost imagine a scene playing out between French and U.S. diplomats where the French ask for their gold and the U.S. goes, "well... here's the thing about your gold, tell you what let us call it even and we will spend a decade or more at war for you? Deal?"

The entire thing is absolutely crazy and the way it is taught to average people is complete bullshit.

> Meanwhile, the U.S. tradition of militarism has coevolved with its status as a reserve currency issuer, meaning that other countries think twice before threatening America’s economic interests.

This is what surprised me the most at first about the September ‘01 attacks: I was certain that no state would try to attack NYC as that would disrupt their own financial system.

Of course the attack was by a non-state actor who was deliberately trying to attack the financial system of Saudi Arabia (plus recruit followers by publicly “striking back against Rome”). It also showed their non-state naïveté by attacking a grandly-named office building rather than an actual organ of world trade (e.g. the CBOT).

>About half of gold is used to make jewelry,

Jewelry, a really useful thing if there ever was one.

You're missing the point here, like all acolytes of the "intrinsic value" cult.

There is no such thing as intrinsic value, as much as most people like to sing themselves that lullaby.

There's is just one thing: supply and demand.

Where demand comes from, whether it is rational or irrational is completely irrelevant to the equation.

People want gold (who knows why, whether it's rational or not, and who cares), the supply is scarce (even though it's not limited) therefore it has value.

People want Bitcoin, the supply is finite, therefore it has value.

Add in the fact that it has some nice properties that gold doesn't have (e.g. easy to move and very hard to confiscate unless you're dumb enough to disclose your holdings) ... you get the price we have today.

People need air, therefore demand is strong. However, supply is - for all intent and purposes - infinite (a bit like the USD), therefore it has no value.

No such thing as intrinsic value.

Just supply and demand.

yeah, there is a definite asymmetry for sure. Bad guys have to get it right once and good guys have to get it right everytime.
Thanks. This is kind of reinforcing my "not actually simple to use" point, though. :)
In Denmark it would be illegal for an employer to discriminate against former inmates _if their crime is irrelevant for the job at hand_.

In practice, though... At least it's automatically erased after (IIRC) five years, depending on severity.
Gold is not priced as a commodity and if everybody is starting to buy oil to store their value, it will stop being a commodity, too. The oil price would go up for a short moment, investments into renewable energies would increase and oil would actually drop in value after it had sucked up the value to be stored.

Can't the increased M2 money supply be interpreted as a move to stabilize the value of the dollar? Maybe the crisis made that increase necessary to maintain the value?
We all want to be like Germany, but do we have the sheer force of will?
> It's hard to argue that tariffs on goods from China don't make it less attractive to buy goods from China.

Disagree. I think this is small minded. So you add a tariff on chinese goods. If they are not the cheapest, then you buy from elsewhere... which still isn't the USA.

And then China does the same thing: retaliating with tariffs, and then buying goods from elsewhere, which isn't the USA either.

So in this game, tariffs probably hurt businesses in both countries.

And, anecdotally: I still buy products from china. More today than 4 years ago. The products for sale on Amazon are often just chinese imports that have been marked up or re-branded. I think it's the exception, rather than the rule, that tariffs did anything positive for someone.
This is something that I've been torn on with all of the M1 benchmarks. All of the benchmarks that are saying "the M1 is so much better than my Intel machine at video work" are all taking advantage of hardware video encode / decode blocks in the M1 (and unified memory between the GPU and video codecs).

Discounting their existence is entirely unfair, as one of the whole points of Apple Silicon is to give Apple the opportunity to put whatever hardware into their computer that accelerates the use cases they envision for their computers. Dedicated hardware is way more power efficient that software implementations.

However, what happens if you work in a video codec that Apple didn't build in hardware support for? Software video codecs depend heavily on SIMD instructions to be performant.
> Over the next 5 years, highly unlikely

This is the problem with the Bitcoin enthusiasts - they think they can predict the future price with near certainty. You don’t think that rosy picture of BTC is held by thousands of others and already baked into the share price? “Highly unlikely” only describes Bitcoin’s potential as a store of value.

If your investing horizon is any amount of time, Bitcoin is not for you. Bitcoin is not an investment, it’s a pure speculation. As another comment perfectly summed it up, lottery tickets are not an investment.
It's a moat for Amazon. That simple.
Maybe you tried it when it was down?

I agree with your view wrt to regulations, but doesn't the article paint a different story? I'm wondering if I understood the article wrong -

As I understand it, the US status as a global reserve currency requires us to maintain a perpetual trade deficit - other countries need dollars and we must give it to them. This is done by buying goods from overseas which has eroded our manufacturing base, as the foreign demand for the dollar is greater than the local demand (which means there is a cheaper manufacturing market).

I'm not sure what regulation you could enact here that wouldn't severely depresses other sectors as they exist today.
I agree, but this seems to me to be something which unfortunately requires a generational strategy to repair, and I don't see how any government that's possible in this country could achieve it. The time horizons aren't long enough and the incentives aren't aligned enough to permit even a credible start.

If I were a black man in America, and they wanted me as a volunteer in Phase 1, I have to say that the history there would be a pretty big negative factor in my mind. Volunteering for Phase 1 is an act of trust, because by definition there's not much data yet. If I were an African-American, I don't know that I would have that kind of trust in big corporations.
So one person could have such outsized effect on a community through the market forces he created.

The effects of inflation are neither instantaneous nor uniformly distributed. Those who obtain the new money first are able to spend it before prices have had time to adjust. As that new money propagates, the prices of the relevant goods and services are bid up.

As such, inflation gives an economic advantage to those who receive the new money sooner, and the consequent higher prices harm those further down the flow.

In short, and contrary to the implication of the above comment, inflation benefits banks and corporations (and by extension, the wealthy and powerful), and harms workers and those on fixed incomes.
* Buy a good screen.

* If you work on a laptop all day, buy an external screen. (Laptop always have small and often a shitty screen)

* Adjust the brightness and the contrast. Do a google search to find some colored images with instructions how to calibrate.

* Quick rules of thumb, you can always reduce brightness to 50% right away. Modern displays are extremely bright and the out of factory settings are insane, sometimes 80% or 100%, it's like starring at a lamppost.

* In terms of positioning. Your eyes should be at the level of the top of the screen. Large displays (24" and above) can go quite tall even with the feet at the lowest position, it might not be possible to do that, it's okay if your eyes are only at 3/4 of the top of the screen.
China treats workers like shit and the environment like shit. The US wouldn’t win a race to the bottom and shouldn’t try.

Instead companies who manufacture in China should be taxed at much higher rates to account for the negative externalities they benefit from otherwise.
Docker is dead. (OK, to be fair, it's still in the process of dying).

As Docker don't solve isolation you need to run Docker in VMs anyway, so actually people start to think how to get rid of this unnecessary overhead. The foreseeable future are microVMs (the hype is just heating, projects show up "everywhere"). And in the long run unikernels could become the "packaging format" for those microVMs (but they have to mature first as ease of use, und performance / stability are not there right now).
Cars drive through cities at that speed regularly. They use highways. That’s what the people are saying. With better strategies for putting cars and non-cars at decent distances, we can allow for cars to go faster with the same or lower risk. The issue right now is that people in cars want higher speeds and pedestrians/cyclists want to go all over the road like cars don’t exist. These two things don’t work and thus we have to go with whatever is the slowest of the equation here (people jumping into the street). The annoying part is when there are low speed limits but almost no pedestrian or cycling traffic on such roads. Highways are frequently an example of that in the US. (Literally no pedestrians or cyclists anywhere near but speed limits are frequently 55mph in some places but 80+ in others - no reasoning for the difference)
My point is that driving at 160 km/h on a fairly empty highway in a manner that is respectful of others is not particularly dangerous. In fact it’s pretty relaxed and routine in Germany for the middle lane of 3 lane derestricted autobahn. The right lane goes 130 km/h, middle lane goes 160 km/h, left lane stays mostly empty except for the occasional person passing. People keep their distance, slow down when there’s traffic in the distance ahead, and strictly adhere to keeping right except to pass. On most modern cars, stopping distance and fuel economy are also pretty reasonable at 160 km/h. I will admit people flying by at over 200 km/h in the left lane can be scary, and stopping distance and fuel economy become terrible for most cars at 200 km/h, though it generally works safely there because of the strict lane etiquette, coupled with people maintaining distance and slowing down in advance when traffic is ahead.

A bigger danger than speeding on clear highways is things like tailgating, weaving between lanes, aggressive passing, and distracted driving. This often happens below speed limits, and is not the focus of automated speed enforcement systems.

In Ontario, Canada, we have wide, well maintained, and well engineered highways that have unreasonably low speed limits of 90 or 100 km/h. While there are times when it’s necessary to drive more slowly (bad weather, traffic ahead), strictly enforcing such limits on wide clear highways in good weather would be silly. People here generally drive 120-130 km/h because cars are designed to operate safely and efficiently at these speeds. Strictly enforcing unreasonably low speed limits would just breed contempt from drivers, so currently the police are lenient with the speeds people actually drive. Strict enforcement of speed limits could be more reasonable if they set realistic speed limits, perhaps variable ones depending on the weather and traffic conditions.
That is especially true for algorithms that are not so easy to put in SIMD.

> But then again, if your workflow is linear algebra heavy, shouldn't you be doing that on a workstation or a cluster and not your little MacBook?

Blender, Gimp / Photoshop, Video Editing, LTSpice / PSpice and Matlab come to mind. These are consumer-ish workflows that benefit from linear algebra, but people want to do them on their laptops.

Hell, people are doing video editing on their PHONES these days, due to the convenience.

Workstations and clusters are not affordable for the vast majority of users.

GPUs probably are affordable however. But these programs aren't really operating on GPUs yet (I mean, Blender and some Video Editing programs are... but LTSpice / Matlab are CPU-only still)

I have not read one single serious justification (as in, empirical) for using gold as the backing of a currency. There are many indications that, historically, the boom and bust cycles that exist naturally are exacerbated when tying the value of currency to (often easily manipulated to be artificially) scarce things like gold.

The world has moved beyond tying the value of our currencies to material goods. Digital "coins" aren't any better, and the same group of fringe types who push the gold standard have taken that over as well.
