Yap. And ARM has the advantage of requiring a smaller frontend. Especially when one looks at wider decoders.

On the other hand if your ISA is the micro-ops directly then the instructions start to take ridiculous amounts of space. It's a balancing act between instruction size (to save instruction cache) and the complexity of decoding them.

And it's not just about being 1:1. It's also about how wide you can go. And variable length encodings simply are fundamentally more hard to parse in parallel fashion. That means a wider unit is harder to achieve, needing more space and power.
+1 for zerotier - I use NextCloud over zerotier.
Yup. I'd love to see some sort of automatic regulation for situations of market failure. E.g., If the 2 largest players in a market have more than an 80% market share, the presumption should be regulation.

In SF, I have multiple ISP options. I get gigabit fiber for $40/month and no nonsense. But my girlfriend lives in an area with Comcast only, where the price is much higher, the service is much worse, and they had loaded her bill down with absurd equipment rental charges.

When sufficient competition doesn't exist, we shouldn't just abandon people to predatory companies.
I would offer the friendly suggestion that perhaps the concept of fairness is not even relevant here.

We want the most competent people to be in positions of responsibility. This is not a fair distribution of responsibility. The fairest system would be a lottery: picking people completely randomly, without regard to socioeconomic status or "merit".

Given that we want the most competent people to be in positions of responsibility, "winning the genetic lottery" is ok, because some people are just born with natural talents. But "winning the socioeconomic lottery" is not ok, because there's no apparent correlation between the wealth of your parents and your personal competence.

Again, fairness is tangential to this problem.
I do wonder if part of Apple's success might just be from accepting a lower clock speed. By allowing more FO4s of wire and gate delay between clock latches you can get more done and have to accept as many compromises in dividing your logic up, say 24 FO4s instead of the standard 16. Less timing overhead lost to the latches and clock jitter. And less pain and energy lost around distributing the clock signal in the first place. You'll never be able to clock as high as more highly pipelined designs but if you beat them through parallelism while using less power that's the design point you need in a mobile processor. You're losing some performance/transistor efficiency in your cores but those are a minority of your wafer size.
Poe's Law is a terrible thing. I assume what you are replying to is sarcasm, because I can't fathom it being earnest.
I've rooted around their build instructions and they suggest this Aliexpress listing: https://www.aliexpress.com/item/32984151266.html

There is also a Croatian company "IstraStream" that will supply a ready-built system: https://globalmeteornetwork.org/?page_id=136

There are a number of eBay listings for camera modules that contain an IMX291 sensor but they don't appear to be the same, and in particular don't appear to take power-over-ethernet. I don't know how easy it would be to integrate one of these, but they mostly ship from China anyway so there doesn't seem to be much advantage over the Aliexpress option.

I also wonder how feasible it would be to use the default Raspberry Pi camera module. Probably the issue is that it is not sufficiently sensitive.
"A meritocracy excels at producing wealth and economic prosperity. "

it does? tens of millions of people are going to be evicted next week even though there are vast sums of money that could be used to help these people. So yes there's "wealth" but the "prosperity" is reserved for a select few. the rest are discarded like trash.

"Universal basic income"

we have that?

"universal healthcare"

we have that?

"unemployment insurance, better public schooling and free job trainings"

not much ?

"these are the kind of Social Justice programs that can share the resulting prosperity among everyone."

but...they DON'T, since there are hardly are any such programs, and what "programs" manage to exist are continuously under threat of being dissolved by those who feel they are "without merit". The ultimate end of a "meritrocratic" system is that when these "meritous" people are rewarded all their well deserved wealth, these lucky few deem everyone else to be "without merit". also commonly referred to as "fuck you, I got mine".
Grab a VPN and that won't be a problem anymore.
Or... in 10 years, we'll have another round of Meltdown, Spectre, etc, because of the big tricks.
Meritocracies work in a very formalized context, like sports, where you can have a single criterion that can be measured objectively and determines the whole activity, because it's possible to prevent gaming of the criteria (even in sports you have this problem with illegal stimulants). The point is sophistry, when you say unbiased clearly nobody is including merit as one of the biases, the problem with meritocracy is that people actually believe in it outside of very specific conditions that make it possible and then confuse non-meritous biases that have yielded profit/status for merit.
> Office 365 is even worse because the low paying users get more frequent updates than high paying users.

AFAIK all office subscribers can change their update channel from monthly (default) to SAC (the one that "high paying users" use). The only difference is that the low paying user has to do it via group policy or registry, whereas the high paying users probably have some sort of enterprise admin tool that allows it to be set at the organization level.
Which makes all this mainly about personal values and not "objective truths".
There are limits, according to the article. 18 months. The judge is choosing to ignore the statute because, well, he is allowed to. The nitpicking over the minutiae is pretty much why we have a legal system.

> Awful searching experience, gated, so many problems

Especially this. It's impossible to find anything when searching on Discord. There are no threads, just channels which easily get thousands of messages per day. Maybe it'd help if those programming servers had logger bots which would index everything and upload it to a website where one could search it, but it still wouldn't solve everything. It feels sad because most of that content is likely going to be lost (it's not searchable anyway). IRC isn't much better in this aspect, but at least it is a more open protocol and one can easily write a program/script to archive the content. Discord on the other hand bans "self-bots" and unofficial clients.

Another problem is being unable to continue a thread after some time, but Reddit has the same problem with their "archived" posts. I personally don't see much value in "archiving" posts except perhaps lowering mental overhead of the moderators. It's frustrating when I almost have the solution to my problem but end up having to open a completely new thread, wait for the right people to notice it and then hope it gets answered in time before it's "archived".

Edit: typo
Maybe it's just semantics - but I believe that is a perceptron (single-layer NN)
Some people on the /r/fasting subreddit go on for 40+ days. I settled into intermittent fasting routine and stopped thinking about extended fasts. I might give it a try. 5 days is quite extreme too, for me anyway.
As you state, it’s based on an overly simplified model. I.e., it’s a heuristic that may not generalize well to the more complex realities of life, depending on what you’re trying to achieve. It’s akin to an objective function of “find a reasonable local optimum solution that requires as little overhead as possible” which can completely miss the global optimum. I was asking for clarification because I was curious how important the “overhead cost” function was as a constraint to the OP. That’s probably where our perspectives diverge; I’m usually willing to take on more of that overhead cost if it can break me out of the local solution.

As an aside, the perspective is appreciated but dismissive approaches to comments (“blah blah blah”) tend to go against HN guidelines. You make good points but I wouldn’t want them to be lost to moderators because of the phrasing
> society rewards extroverts as leaders

It's even worse: some societies reward quick thinking and shun deep thinking.

Mostly the English-speaking societies, people can even become unsettled or giggle if they see someone staring at a wall, deep in though.
Ask HN: Earning 100k EUR in Berlin?
I am a Ruby programmer with 10 years experience, based in Berlin, Germany, earning around 60k EUR. I also have some Python and JavaScript experience. I'd same I'm a mid-level engineer, not working on anything super trendy or complex. I'm in my 40s. I see lots of people on HN with salaries in the 100k region and above, but usually in the US. Is it possible for someone like me, staying in Berlin, to reach 100k EUR within a few years?

Some usb drives are much slower than a decent sd card. Also, the ultra has cooling issues.

However, there are usb3 nvme enclosures that are incredibly cheap, and blow both out of the water:

https://www.jeffgeerling.com/blog/2020/fastest-usb-storage-o...

For a build like the one in the article, I imagine something that puts two nvme sticks beside each other, sandwiched between every other rpi, with passive aluminum heat shields in the remainder of the spaces between the rpi’s. I bet it could be even denser (more pis and more storage) and quieter.

I wonder if space can be saved by making a heat shield heatsink that has a pi on both sides, and fins in the middle.

Super cool article.
The alternatives to stenting and surgery that this scientist recommends, in her own words, are:

"Major improvements can simply be made by medical – as opposed to procedural – interventions, such as the adoption of healthier lifestyles, anti-cholesterol drugs, taking blood pressure [drugs] and cutting out smoking.”

How are these "surgery alternatives" if the underlying cause is usually years of lifestyle choices? Is the doctor expected to tell patients to lose weight and quit smoking, and send them home? So much of medicine has this conundrum. Patients don't simply change as expected and they will also seek out treatment if none is offered otherwise.
The PS3 did something like this. One processing unit of the Cell processor was reserved for the OS while the rest could be used for games.
I completely agree here. In "Think Fast and Slow" the author talks about how much more productive and clear his time was when he took his thinking time and walked for it.
That's the disconnect here I think.

SAR is a technique for building up a two dimensional image by rasterizing one dimensional signal reflection data. Any type of radiant energy would presumably support SAR techniques, from sonar to x rays, although the 'R' in SAR presumably limits it to radio frequency range (~30Hz-300GHz). Some of which, as I mentioned originally, absolutely would see through buildings.

My point is that the headline and article are trying to make the case that 'SAR can't see through buildings', when it should be 'Why it looks like our satellites are seeing through buildings' because that is all that is explained.

All the best for your new Oil shell, and I agree that we need to have similar to POSIX standard for distributed systems but it must put local-first software as the first class citizen [1].

Different, but a related topic that I've come to be fascinated by are athletic tools and techniques that are held as canon that turn out to have no scientific support.

The author talks about reactions of physicians dismissing convincing data — the befuddlement and dismissals — and it's the same reaction athletes and coaches give when they're part of some of a controlled trial.
Written in a highly partisan style.

Serious charges, followed by exculpatory explanations that sound lame in comparison.
Ciao jlgaddis Jack in Video Camera Control used PJON over PJDL which is a wired data link that needs only ground and a data cable to connect up to 255 devices, cables can be up to 2km long at the slowest baudrate (1.97kB/s - 15808Bd). PJDL in few words is a sort of open 1-Wire with a longer range, support for more devices and a stronger immunity to noise.
See: https://github.com/gioblu/PJON/blob/master/src/strategies/So...

The core of the community uses PJON over PJDL in home automation systems, irrigation systems, feeding systems ecc. Soon Mysensors will include PJON over PJDL in their list of supported transports. PJON works also over TCP, UDP, MQTT, ESPNOW, LoRa ecc. so generally a router is built and programmed to run 2 instances of PJON for example PJDL and MQTT, to then route data to and from a process running on a real-time operative system

See: https://github.com/gioblu/PJON/blob/master/examples/routing/...

which can also run PJON thanks to the wide support of the implementation.

See: https://github.com/gioblu/PJON/wiki

Looks to be handy for many to connect devices, even on different media.

Although many also use PJON to implement mesh or peer-to-peer networks, there is a group in Australia building such a network using PJON over LoRa.

I must say I hope we will be able to start building a private network infrastructure with it, that would be awesome.

Companies and institutions are also implementing PJON within their products and services. AD24, a Czech company, recently created a mesh network over PJON to connect advertising monitors around the city of Prague. It looks there are also few companies in Germany which use PJON to create real world automation systems.

Recently contacted by the Universitat Politècnica de València (UPV) to support the development of a PJON network of temperature and humidity sensors to monitor the vault of the Cathedral of Valencia and avoid its decay, I hope this will end up done, it would be really rewarding.

We had this when game consoles were very dominant: PS3/Xbox360 era, start of the PS4/Xbox One era. Games were developed for consoles and then "touched up" for PC. It sucked. Starting from good machines and pushing them is far better imho. They should have cut off the base versions of both last gen consoles, but Sony/MS don't allow that afaik (e.g. either you don't deliver for PS4 at all or you deliver for PS4 and PS4 pro). At some point you have to realize that hardware is too old for something and accept it.
Indentation was seen as a defect when presses were in use. it's only these days when we want to show that a letterpress was used that we have indentations.
That's not actually how it went, either. One of the major aims of the BBC Micro was educational use, with use in TV an afterthought, and the processor was designed after they'd already made several MOS-based computers.
> What? Maybe extremist groups like the proud boys, but I’ve literally never heard this objection

I meant this part as quite analogous to the drug debate. People dislike drug comsumers because they feel drugs are a cheat: you get unearned pleasure without having to work for it. You sidestep your noble duties of working and earning the fruits of your labours by short-circuiting and hooking your brain directly on to pleasure juices. I think -- said explicitly or not -- a lot of the same sentiment underlies the anti-porn stance. That men can get (part of) the pleasure without the work. The underlying idea is that without porn, men would be forced to rather work on themselves, improve themselves, mature and provide value to society to attract female attention etc. Just like the (misguided or not) idea that without drugs all the junkies would suddenly go take on a decent 9-5 job and climb the ladder like one is supposed to and indulge in buying stuff with their hard earned money. Just outlining a narrative, not that I believe this simplified story, just that I think these patterns are lurking there, it's not merely about showing bodies and genitals due to some irrational arbitrary taboo.

> Again, thats an extremist misogynistic viewpoint. The real objections I’ve heard concern the exploitation of the industry and the lack of protections for workers.

What people say in public to look good is different from what they act out. Despite all the liberal attitudes in western europe for example, if you go to a brothel in Amsterdam, you won't see rich Dutch girls self-actualizing, or middle-class Norwegian girls expressing their empowered sexuality, but poor Bulgarians, Ukraininans, Hungarians, Roma, etc.

Sure there are exceptions. But overall even most of the enlightened liberal Western European parents don't actually want their daughter to become a pornstar or a prostitute. For reasons approximating my previous comment -- that they are worth more than their mere bodily appearance, etc.
It will be interesting to see, but both macOS and Windows already run on ARM and it is a widely known instruction-set. For companies to suddenly switch to RISC-V instead I think there needs to be some very clear advantages.

I am starting to see hints that RISC-V designs may be able to outperform ARM by a good margin. But thus far I don't think that is a firmly established truth.

I don't see the numbers on HN? Which is why it is less addictive to me than Reddit.
I also lurked for nearly 2 years, as I was concerned about diluting conversations with low quality, unnecessary posts, which are far less frequent on HN than Reddit.

edit: Now I see the numbers. The quality of posts is still far better than Reddit and the interactions less addictive, at least in my experience.
Right? It's still so amazing. I would say more amazing than ever (thanks to new trailblazers like Alexandra Elbakyan).

I was just a kid growing up far removed from the information and happenings of the rest of the world and the web was this magical new thing that connected me to it. It was a bit of a firehose at first (well, I guess still is), but I loved it.

The only difference between now and then is that now I know how it all works. Back then the technology was completely magic. It's still just as magical in the human sense, and I am so grateful to TBL and CERN for making it happen and giving it the public! It has been so game changing for me and I grew up in the USA, I have to imagine it would be even more game changing to people curious about the world who grew up in more remote places.
> I only care about how it performs and how much it costs.

> I honestly don't care if my CPU has 2 cores or 20 cores

So first means: "my only concerns are performance and cost". What determines performance and cost? Primary answer: number of cores. If you care about performance, you care if the CPU has 2 or 20 cores. If you care about cost, you care if the CPU has 2 or 20 cores. You might not articulate your concerns in this way, but they are intimately bound together.

If you only care about "good enough" performance and "in my range" cost, then your concerns are still bound up with core count.

So what's your apparently more correct understanding of some of those words?

Idle as in powered on, not sleeping, just 'no' workload? I stand corrected if so, I didn't realise that was the case.

I also like the idea of having an easy homogeneous setup, each Pi having one disk, vs. my alternative (old PC parts) being something like '4 SATA ports on this one, and 6 on that one, but one's broken, less one on each for the boot disk' - I quite like the idea of having a bunch of Pis, and one image that I apply to all of them, which can include details like /dev/sda being its only data disk. That's not really a functional advantage, just appealing for keeping it simple to come back to and remember/understand how I set it up when I need to tweak something (and really easy to add another one increasing available cpu/ram/disk).
Nowhere in the comment you're replying to is it stated or even implied that men suffer a significant social stigma from consuming porn, nor that women DON'T suffer a social stigma for producing it. The viewpoint you describe is certainly twisted, but it hasn't actually been expressed by anyone.
So let me get this straight, you 1. Come in bragging about how self-disciplined you are for not using social media on a social media platform and then 2. Get very defensive when someone points it out to you and 3. Assume the only possible reason anyone could disagree with you is that they’re trying to get internet points?
