I've been through this experience myself, so I know what you mean! The best resource I found was something provided by my local university called "Mathercize" (may just be something specific to them), which gave you a range of problems you could complete online, with a brief run-down of the theory on how to solve them. It was positioned as a "refresher" on maths for those doing college-level study, and in my case the problem sets were designed for MBA students.

Maybe looking around for these kinds of refreshers rather than discrete textbooks in their own right is your best bet? I know that I encountered analysis paralysis when trying to re-learn "everything" from the ground up, and got nowhere as the information wasn't curated enough for my needs.

Barring this, I found the "MathIsFun" to be the best all-round resource for grokking foreign math concepts.
Wow!!! I thank you!
Typescript lacks the goal of soundness, which makes it much easier to introduce powerful features than in Haskell.
Yeah it’s amazing how people don’t research basic facts.

Despite my grumbling at the lack of ram on the MBP, I might just have to buy the Air in honour of my 1988 Archimedes.
It's a good point but so far I don't think there's a way to open the debugging Chrome port on mobile and connect to it. But I think that probably should be some way, it's just not obvious to me right now.
I wonder if M1 dominates an i9-9980HK at multithreaded workloads that make full use of available SIMD? Does an M1 dominate at peak theoretical flops?
Here is my definition:

In this context, a professional is someone whose productivity is limited by the power of the computer. A developer compiling large code base on their computer. A person doing video editing. These are examples. And maybe “professional” is the wrong term, but I think that is what people are aiming for when they use that word in this context.

Think of a framework like Laravel; you can make the Laravel app write "Link" headers for each of the JS or CSS assets declared in its views being rendered. Then, a server, say Caddy which supports push out of the box https://caddyserver.com/docs/caddyfile/directives/push will read the Link headers from the response from PHP, and push them on its behalf. Super simple to implement.

Adoption has been low because there hasn't been enough time for people to get comfortable with and switch to more modern web servers that support this type of thing, and most frameworks haven't figured out that having these sorts of features on by default could have major benefits. But it could happen.
Are there any manufacturers working on similar high-performance-per-watt CPUs for PC, i.e. Win10 on ARM? I know that ARM servers are a thing but it all seems very quiet on the laptop/desktop front.

"Most of our biggest Mars advocates currently are wealthy white men who own aerospace companies. In other words, they aren’t just interested in exploring Mars for its own sake — or creating human habitats for the good of all people."

How is this not considered hate speech? Is it just commonly accepted now that all rich white men are evil?

The article made some interesting arguments and I don't want to start a argument, but when I think of Musk, Branson and Bezos, I believe they are all persuing space for the betterment of mankind not self enrichment or empowerment. They already have vast wealth and power and there are far more profitable or evil ventures available for them to exploit if they really wanted to.

WebRTC does not seem intrinsically more difficult to work with than WebTransport (as someone who works with WebRTC daily at super low levels and also has read about WebTransport and even watched talks about it at the standards committee and is now just annoyed as they didn't even have the decency to replace all of the WebRTC data channel use cases :/). WebRTC is actually a ridiculously easy stack: it is seriously just SCTP over DTLS (with a small bit of ICE, to maintain the connection, that isn't really required anyway). To the extent to which the code sucks--and that's frankly the core problem literally everyone has with it--it can be fixed pretty easily rather than tacking more BS on top, but somehow everyone wants to fix it with new specifications rather than improving the engineering (which I think is related to the problem the other comment brings up); even just some better build engineering would make it easier to compile (which is the #1 reason people seem to hate on WebRTC, not that it is actually *that difficult to compile... but it certainly isn't an invalid complaint).

>A company like BMW needs a lot of electricity to produce a car, but the factories are built with capacity to spare

So interestingly, one of the reasons why the steam engine took off in working factories was because you didn't have to rely on the intermittent nature of water or wind power.
The saddest thing about YouTube disappearing would be losing the vast trove of educational content that has amassed over the years. We live in a unique time in history when you can go online and learn how to do absolutely anything you want for free. I feel like the majority of people still hugely underestimate how valuable this is. Granted, there's a lot of junk to wade through. But the information is out there.
Arm-Based Macs: The End of Windows PCs?
We say the 'pro' in MacBook Pro hasn't stood for professional grade equipment in at least a decade, but for equipment for someone who considers themself to be a professional.

People also regularly misplace their importance and prevalence in industry. For instance, you see more Linux than Mac in the big color and VFX houses.

It's important to trust and value your tools, which is how prosumers generally feel about their Macs, and they do make nice frontends for the computers that perform the actual work.
I confess, that now I've looked at all the details, I can't argue that they've done the right thing. It seemed to me that it was daft to launch an MBP13 with less RAM than the intel, but in fact the M1 is so far ahead in every other respect that it would be foolish not to give people that option.

I might have to get an Air for myself, just to have an ARM based computer again, like it's 1988.

Most professionals aren't software developers and don't need to run virtual machines.

But regardless of professional requirements, "Pro" in Apple's product line just means "the more expensive slightly better version." Nobody's arguing that AirPods Pro are the wireless earbuds of choice for people who make money by listening to wireless earbuds.

I have to agree, but I wouldn’t be a dick about it. Lots of people enjoyed this book. For me, I can’t get through the first 30 seconds. My brain just rebels against this style. Partly because there’s something wrong with me, I can’t understand comics. Doesn’t mean it’s the worst book ever, it just doesn’t work for me. But it did have the effect of turning me off Ruby permanently.
Add MQTT to your lists of event buses.

MQTT is lightweight and fits nicely into IoT sources, backend streaming and even scalable frontend distribution to browser or mobile clients. I recently did a quick'n'dirty PoC with paho.js and D3.js for live charting in the browser.

In a pub-sub event-driven world, CQRS just means having distinct events for: Commands to do something; Query matches (CEP-style); and other Notifications that something has happened. Queries are compiled and unfolded into streaming operator graphs, delivering match events to the client. Queries and their operator graphs can be factored to share common sub-expressions (like the RETE rules algorithm).

A good start-up idea would be MQTT 'appstreamer' framework, with model-driven message formats, validation and APIs, together with pluggable engines for CEP queries, rules, workflows, constraint solvers and other business logic.
Yes.

Hello everyone! Thank you for the love I really appreciate it. I did not expect this to blow up like it has I got up this morning and it was sitting on front page and there's a lot more interest which is great. I feel sad for some people to see that they are having issues with the binaries/connecting to chrome, I will get to work on that today and hopefully have some resolutions pushed out in half a day, so please check back for update. And I really appreciate all the feedback, it's very good to know how people are experiencing this. Thank you again for all your support.
Did you mean Hadoop/HDFS? HBase works pretty analogously to Bigtable (though, having run HBase in production at $dayjob-1, I'd take the latter any day).
That is not 'exactly' what they're doing. It's loosely what they're doing.

Being grandfathered into a service means you get to keep using it the way you did, full stop.

This service is about uploading and downloading files. All they're preserving is the ability to download them, not upload.

Really it's better to use a fast language like Go or Java for huge loads like this.

Our typical CRUD Spring backends can handle ~15,000 requests a second with no optimization.

Looks like I’m getting a new Macbook air instead of MacBook Pro
Yes, I guess it's a bit arrogant to suggest that this one form of media is somehow different from all the others that came before it, and we've somehow finally reached the optimum because YouTube is special for some reason. Nobody can really pretend to know this at present. Maybe I was more imagining what the future would be like if it were true, looking back on the present.

Although, when AOL was around you could only practically use the Internet from a large desktop machine, but now you can access a massive amount of information from almost anywhere using a smartphone. And we're being introduced to computers at a younger age, and are spending more time with them. But that might not be indicative of what happens in the future.
Who goes from axiomatic set theory at all, if their goal is not to be a logician/type theorist? One does not need to know axiomatic set theory to study linear algebra any more than one needs to know about semiconductors in order to program in Python.

Asking out of curiosity - isn't this similar to what Venti (from Plan 9) did? Of course, Venti was content-addressed, and in this case I'm guessing this system sat above WAFL (which is definitely not content-addressed).

Every time one of these articles is put out with that kind of a tone, people out there become more emboldened with the phrase “it’s okay to be white.”

Yes, it’s hate speech, but it’s tolerated and encouraged by most websites and media channels.
this sounds interesting - would you be able to add few more examples of where this could come in useful?
I don’t find this to be true. The Push is simply a remote control for the software and it controls features that already exist in the DAW. I don’t believe Ableton is hindering other manufacturer’s MIDI or SysEx integration. It’s strength is in it’s specificity and the fact that it is custom-tailored to Ableton Live alone and does not need to be some middle-of-the-road hardware device that also has to make sense with every other DAW.

I owned a Push 2 for 2 years before I sold it, and in my experience there is very little (if anything) it does that cannot be done with a 1:1 analogue in the software.
> Not much of it actually helps me.

This is an excellent point. With the multitudes of content competing for our attention, it's important to be very selective and deliberate with usage. Otherwise, it can very easily turn into an addiction - you'll be mindlessly enjoying the dopamine hits of watching "interesting" videos whilst life passes by.
Especially when the service is of the social networking sort. Your friends don't move just because you do, or they might not move to the same place.

In my experience in IT support there are very few people where this is actually the case.

For most people their ability to use the computer is the blocker. This also involves the ability yo make sane file format/compression decisions if they work with graphics or video.

This is where I’m at too. Compromising Little Snitch and VPNs is just a bridge too far. It’s cool that they got this level of performance in a lightweight form factor, less so when it enables the worse of surveillance practices.

I'm curious for Windows users what can we hope for from Arm/AMD? It's kind of depressing seeing how well Apple and their ecosystem is coming along. Being able to run apps natively on your laptop sounds amazing. Android and Windows are far away from that level of cohesion. There's Phone Link, but running apps using that is clunky and slow.
They haven't done anything to cripple other controllers. In fact, they keep adding new classes of controllers all the time -Live 11 now supports MPE.

That's disputed. But when they get around to updating that 16-inch next year, holy smokes.
Is this a thought experiment or are you actually wanting to create an alternative to YouTube?

In the same boat. My 2015 is great but for the fact I do a lot of video and photo editing these days, and those apps push this machine to its limits. My fan runs at the highest speed all day.
I read this whole post saying "barrymetrics" in my mind and only when the genesis of the idea was explained did I twig that it's probably bare-metrics.

So performant premium that I’m thinking of calling Apple about my MBP preorder and switching it to the Air.

Last thing I need is a MacBook Air equivalent with an unnecessarily loud and annoying fan.
> And it's doing this while using more than an order of magnitude less power (10W vs. a TDP of 125W for that Intel part).

That's the wrong conclusion to make. For instance, the Lenovo ThinkBook 14s (with a Ryzen 4800u) with a 15W TDP posts the same Geekbench multicore scores [1] as the M1 Macbook. But the ThinkBook isn't in any way faster than the top-end iMac for real world compute intensive tasks.

The M1 certainly looks efficient, but there's little you can conclude from a single benchmark running for a very short period of time.

If this were possible/feasible, why have there been no successful and large scale examples of this happening on earth? Say, in the middle of the Pacific ocean.
I think there is also a moral angle that disturbs Windows fans to this as well: This is validation that Apple's heavy-handed walled-garden approach can, in fact, work and even sometimes beat an open ecosystem. That's freaky.

It's not a process thing. The left-side TB3 controller freaks out under sustained load and can drive the system to a crawl. We have to unplug one of our LG 4/5Ks and run the other+power on the right when we want to be able to do back to back video conferencing.

It's been a running joke in corporate for years that Apple's "premium fan noise" is a brilliant branding move because you can identify the Mac users as soon as they unmute.

But are the people who would drop $120 to find a partner the same people who belong to that 6.2%?
It’s a generalization, of course there are exceptions
OK... but let's say it's 95% there, even. How much power does an M1 draw compared to a 5950X? It's not even funny. And the M1 is running at a lower clock.
Completely agree, and I haven't thought about that angle enough.

They mentioned two advantages over Mars in the article:

* gravity (and bone density)

* radiation

Over Earth? Absolutely no advantage, other than maybe it is easier to get approval to build a giant blimp. But I feel like if you wanted to build a floating city in international waters nobody would get in your way. They might rob you, though.
