>5. THE RISC-V ECOSYSTEM IS GROWING RAPIDLY

Is there a desktop class CPU and a server class CPU in RISC-V space which can compete for money with X86 and ARM?

If not, the how much time it will take?

I'm trying to understand what "growing rapidly" means.
The original darpa paper is what the TCP/IP stack is still based on right ? It feels like it was never even intended to be at the scale its deployed on. Which amazes me to be honest that people have somehow gotten it to work to this scale.
> At no point did the episode show this as a good thing.

But the question isn't whether it's shown as a good thing, the bar was "Violence [is] the failure to solve a problem, never [a] true solution." Presenting the violence as necessary is still diametrically opposed to this, in some ways even more than showing violence in a positive but unnecessary light.

That's a genuinely uncommon attitude in genre fiction. Reducing it to any situation where a show posits "do the ends justify the means? perhaps!" - which is the basis of like, every piece of high-stakes TV today - does a disservice to the original critique and the TNG episodes which argue otherwise (and frankly, also to the deftness with which DS9 does usually present it).
You don't have to disagree with Elon as a person or politically to feel that an open speech platform controlled by one person who is known to micromanage everyone around him is bad.

The congestion control algorithms have been significantly improved since then. But yes it’s a testament to how good the original design is that it’s still what we use today.

Protocols like SCTP and QUIC work similarly but can avoid head-of-like blocking.

Hey, thanks for the comment.

Its true, a document and a selfie are not enough in some cases. there are a couple of technics to make a better guess if the selfie was live but they are not good as liveliness checks.

We already started to work on a liveliness step with a customizable challenge, meaning the developers can configure what action the user should perform in this step (like turning the head in a specific direction, perform hand gestures, and more).

The mobile SDK's will have more sophisticated tools to detect fraud, we will write about it soon.
The newer “4D imaging” radars can track stationary objects too. This is what the self driving companies have turned to in recent times.
It’s pretty easy to do in a lot of countries. The US doesn't require ID to buy some pay-as-you-go SIMs.

Of course, you could probably determine identity either from video cameras or, more likely, people using the phone and connecting to various towers, but you if you were diligent you could make it really hard.
Active Directory, Exchange and to a lower level Citrix are the answer.

Very few businesses think they can do without those. IT history of these 30 last years have kind of segregated sysadmin/architects types. The one focused on internal IT / desktop services solutions are typically more knowledgeable in Microsoft technologies while unix/linux sysadmins usually focus on the non desktop/office related stuff. Despite decent solutions existing without Microsoft, very few people know enough about them to recommend them.

The architecture is just one part of the groundwork for an entirely different philosophy on what a prison should be.
In many countries it is.

My banking and bill paying is basically online only. It's not obligatory but it's far, far more convenient online.

Debit cards still exist but they are being phased out slowly in favor of NFC.

To board transport I can still use a card but recharging it is easier via an app than by standing in line at a machine where I'd have to pay with a card or cash.

At work we often communicate via group chats. It's quicker and less intrusive than phoning or emailing. I don't love it but I'm accustomed.

To pay taxes or fines to report to the city that a tree branch fell to consult my property tax info or medical records or to get an appointment for minor surgery - it's all easiest or only possible online.

Online means via app on phone generally. Most of us don't carry around anything more expensive than a 150 euro Chinese phone.
No.

Server A also sends messages coming from servers it federates with, so those on server C can see server B's messages, but C'ers just can't reply to them and expect B'ers to actually receive those messages.
they don't. you ask the team to come to a consensus on their own and if they don't just pick someone to make the decision and then pick someone else the next time you have to pick

managers thinking they know better than their reports is the source of basically all team dysfunction in tech
The phrasing they use is a bit confusing. "Speech" is not a clear quality description, so it's odd to compare speech to a CD quality recording (presumably 44.1 kHz). Speech can also be sampled at CD quality. If they meant to emphasize the difference in frequency range or dynamic range - there were, perhaps, better ways to do that (e.g. "telephone conversation" vs "symphonic orchestra recording").
We can. It just depends on how much money. Everything has a price.
I wonder if the managers manage each other or if they are all managing the developer.
Since there is no perceptual difference to humans between 44.1 and 48 kHz, the statement about CD quality is perfectly fine - even more so as they operate on the higher sample rate.

Most research in that field operates at 16kHz. Enough for most speech applications, not enough for CD quality. In general, CD quality in this field means a high enough sample rate that you can play all audible frequencies.
> 90% of the heat in that water currently goes down the drain.

I think this number is very flawed, at least if we talk about bath and not shower. Kids sometimes play in bath until the water is "cold". Even if they just wash, the resulting water is far cry from what it was when "inputted" into bath.

Moreover, all that temp won't be recovered to heat air. Some energy goes to heat bath itself, some goes to heat space under bath and some goes to heat air. So I suspect the impact numbers to be far less benefit. And the result will be slightly warmer bath, but no effect to overall heating.

But it is true that water is hungry for energy. My avg energy usage is 550kWh and I have electrical water heater. It takes exactly half of total energy usage per month.
Without wanting to sound negative, as long as the cell network's function is to ensure that when someone dials 1-234-567-8901 my phone rings, won't they always need to know my phone's location, and the number-to-handset mapping?
The Wii U was such a fun console with so many great games, it's a shame that it was relatively inaccessible due to horribly bodged marketing and weird choices - luckily they're porting most(but not all) of the gems. I actually think that the gamepad screen did contribute a lot to a lot of games, especially if there was a lot of action and you were able to use it as a map/for quick actions.

It's good that they basically built a product that was impossible to market badly with the switch, it probably sells itself, considering the form factor and all of the first and third party support they have now.
Are you looking for investors, and if so, have you told them about your next idea yet?

There will never be a regulatory framework in which flying cars are allowed in urban airspace/ground space except perhaps in certain very special locations (like Saudi Arabia and maybe Florida) where there is rule of the rich rather than rule of law.
I find very strange the claim that a moving doppler (pulsed doppler?) radar 'generally doesn't help to detect stationary objects'. I mean if the car is moving, it generates a doppler shift on all objects moving at a different speed, right?

Maybe it's difficult for reasons of false alarm detection (too many stationary objects that are not of interest) but you can get very good results with tracking (curious about these radars' refresh rate), STAP, and classification/identification algorithms, especially if you have a somewhat modern beamformed signal (so, some kind instant spatial information). Active-tracking can also be of help here if you can beamsteer (put more energy, more waveform diversity on the target, increase the refresh rate). Can't these radars do any of those 'state of the art 20 years ago' stuff?

There's something I don't get here and I feel I need some education...
The numbers aren’t that large. Nowhere near the volume of optical components sold, which benefit from continual optimization that the billions consumer electronics sold each year undergo.
It replaces TCP+TLS, and runs multiple streams on the same conn, supports transition from eg wifi to ethernet on at least one of the nodes. And since it's over udp implementations are mostly in user space. Which is good if you want it now, but not great for performance. Ip packets are very small so you gotta have either kernel support for quic or batch IO, otherwise it's often CPU limited (yes, really). In addition congestion control is wonky, unfortunately. In my experience (quic-go), it's too shy in the presence of TCP streams, which ends up getting more bandwidth. But that depends on the algorithm used, implementation and God knows what else.
A few years ago (when QUIC was coming out) I was developing the theory of a new transport/encryption/authentication protocol. The focus was as much on transport as in the built-in federated authentication.

There was not much interest in the field and I had a lot of the theory and formal proofs, but no implementation.

This month I found a cofounder and we are reordering a lot of the information and presentation, we should start asking for funds in more or less a month.

I still believe my solution to be much more complete than anything in use today (again: on paper), but since there seems to be some interest today, I'll ask here: Can anyone suggest some seed funds to check for a starttup? We will be based half US, half EU.

“Elephant” flows are a definitely a thing.

It all depends on the application and overall use in of the network.

With sufficient flows and a mix of sizes it’ll still tend to even out. But if you’ve significant high-throughout, long lived flows this is definitely something you might hit.
Great post. I like the closing:

Ultimately, we decided the best thing to do was to do nothing and hope for the best.

All of the experienced network engineers that I've worked with who have run into issues that feel like they can be improved by tweaking QoS somewhat, always end up saying to me, "Nah. Just get a bigger/more pipes." I've never been in a position like yours to make a cogent argument as to why they were wrong, and laid out the details as well as you did there.
Dark mode isn't necessary better for your eyes than light mode [1]. I prefer a consistent lightning more, and that is often easier done with light mode. Although, this is getting better since more and more sites and apps implement it. However, not all, this results in sometimes being surprised by a white flash after browsing through some darker sites.

Even if you could get that to work someone would take a cellphone to the secret meeting and share a geotagged selfie, people just can't help themselves. Hello secret police!

Or, they'd somehow manage to control themselves, but would only turn off their cellphone just before they got there. It would be easy to figure out the pattern of a bunch of likely instigators heading to the same location.

Or, people would somehow learn to leave their cellphone at home. If anyone's then stopped by the police not having a cellphone in your pocket would be extremely suspicious in a totalitarian dictatorship.

Even then it's not Italy in the 1800s. There's surveillance cameras on every corner, and you're right back to the problem of no signal being the signal.

Nobody in Naples was filing multiple notices in their local papers before they had a normal meeting with their friends on a Tuesday, but that's what everyone's doing via social media. You can tease out suspicious meetings of any non-trivial size as being those without such a signal.

The only way this is going to work for any amount of time is if it's organized like modern terrorist cells, but that's assuming a lot of steps between angry students staging demonstrations and covert operatives.
Because that makes incoming traffic not to come to them at all. Traffic costs money and usually much more than a single 1U colo cost.

Then order some sodium batteries from CATL. They're building around a TWh/yr of production which uses the same infrastructure for both sodium and lithium.

Compare to the state of FNR reactors, where there is a single reactor (yet to close the fuel cycle even experimentally) that doesn't catch fire constantly (if you believe the russian government).

Where I live in Europe the phone is used to charge transport cards, to pay at stores, to interact with banks and government, etc. Because of two factor authentication it's basically a necessity to have one for banking and certain government transactions (some of which can only be done online). I could carry around a laptop for work and business but it's far more convenient to use a smaller device.
This lines up with my experience. The person making constant "tactical" changes looks super productive. But they just deferred the productivity cost. You end up continuing to deal with their fragile mess for the rest of the lifetime of the product.

I fully understand that there are circumstances where true tactical changes do make sense, but the tradeoffs should be considered up front.
That would have been useful back when my son was a few days old and they needed to find a vein. They had to bring down an ultrasound machine, and had to keep looking for usable vein. There were multiple failed attempts, each one painful.

That is socialism and it's no wonder why some leftists love corporations. It's because many corporations are examples of applied socialism.

I don't know if you're addressing what makes a good "EV" or just listing some features you personally care about. If the former, then 360 degree camera and build quality has little to do with an EV. Tesla is a young company and build quality has dramatically improved over the years (see Munro) and will continue to do so. Tesla has close to 360 camera coverage, it just hasn't added it in software. All it takes is a software update on existing hardware. If they haven't done it yet, it probably means they have other priorities at the moment.

Some EV specific advantages of Tesla over competition:

- Range: Teslas continue to lead in range, as result of best aerodynamics, best drive train efficiency and vertically integrated design (see Munro - highly integrated component).

- Charging infrastructure: largest available and most reliable (see MKBHD for e.g.).

- Regular software updates improving everything from range, to charge planning (recently added much better estimate based on wind direction, inclination, tyre pressure, weather, etc) to safety, etc.

- and most important of all: Availability and production volume. Best EV in the world isn't worth anything if you can't buy it.

If you look forward and see what Tesla is doing with its manufacturing innovations, it should become clear that things like in-house battery production, single front and rear casting among numerous other things has already secured their top position for sometime to come.

> What are these people thinking?

They don't. MOre so - they don't even know what they are doing.

NB there are people on the other side of the spectrum - I've met enough Linux fanboys who insisted what they don't need a firewall running on their public machines, because... Linux is safe.
That's exactly my point.

Unless Teslas have something similar to the human brain cameras are not enough.
It’s beyond obvious that water flew as rivers in Mars at some point, and looks like there’s some water there even now!

Even life, is there any reason to think there WASNT some microscopic life there at some point? I doubt anyone thinks there’s viable life there even now (though one can’t 100% exclude the possibility).

It’s like everyone kind of already knows these are the likely facts but we keep using these as scapegoat questions to fund more missions for rovers etc. Instead, wouldn’t it be better if we are honest to oursleves and find things we actually want to do? Like get some people there? Which again, more than the science is just about the accomplishment itself.

I’m genuinely curious about places like Europa. I’m not at all curious about digging more Martian dirt and doing increasingly insignificant geology on a dead planet.

Networking is boring and difficult at the same time. Most of the tools are very outdated (i.e. cli - except probably palo alto and juniper gear) and troubleshooting is a nightmare. Modern infra is also not a piece of cake, with k8s everywhere nowadays, but it’s linux under the hood and most of the times troubleshooting is easy. Also, it is much more fun for me, but it’s about personal preferences.

OK, I got it now. Thanks.

You are right, the compiler for a statically typed language can do checks that are impossible to perform for a language like Ruby, that could also create methods calls and add arguments at runtime.

I tend not to use metaprogramming except some object.send(method, args) when strictly necessary. The reason is that it slows down the team when trying to understand what a piece of code does and if not properly understood it generates bugs. Metaprogramming is buried down into third party libraries (e.g.: Rails) but we are not testing it there.

I occasionally get bugs that a compiler would catch, maybe one every year or two. One happened on Python this year. I can't remember what. I should dig into slack: I remember I wrote a note to my customer (maybe the classic id as string vs int?) But the time not lost writing type annotations is immense. I wasted cumulative weeks on that when I was working in Java 10+ years ago. And cumulative weeks of malloc/free when I was working in C before Java. All considered I prefer the occasional bug and extra test in Ruby and Python. I consider that path (GC and no types) an improvement. Of course it costs performances but customers are happy running Ruby and Python and are still in business. It can't be wrong
What is HAKMEM? Seems like a collection of notes on ..math?
Never thought about that before. Ethernet supports extremely high levels of data transmission. ISB C for intrgrated charging ND data transfer makes sense, but why are there HDMI cables?
I have very little reason to believe life evolved in Earth or even in Mars for that matter. The more likely scenario is that there’s rocks floating around everywhere that have spores of life throughout the galaxy ready to seed a suitable planet in geologically instantaneous timelines. That will explain the extremely rapid emergence of life on earth initially while it took a few billion years to evolve any further. In which case if Mars had flowing water at some point it likely also harbored at least single cell life.

First paragraph says "in-house infrastructure"
HAKMEM, alternatively known as AI Memo 239, is a February 1972 "memo" (technical report) of the MIT AI Lab containing a wide variety of hacks, including useful and clever algorithms for mathematical computation, some number theory and schematic diagrams for hardware – in Guy L. Steele's words, "a bizarre and eclectic potpourri of technical trivia". Contributors included about two dozen members and associates of the AI Lab. The title of the report is short for "hacks memo", abbreviated to six upper case characters that would fit in a single PDP-10 machine word (using a six-bit character set).
