well.. isn't that how it supposed to work? science, i mean

start with data -> build a model -> test your model on new data

and if doesn't strongly conform to data, than throw it away and start again

now, it doesn't mean the model has to match neurophysiological data at the very low level, e.g. neural spikes trains and all the related biochemistry and regulatory pathways and whatnot, no need to go to the rabbit hole in order to come up with a working theory at some level of abstraction.

Just like Newton didn't need to go to the atom level to come up with macro view of natural laws, and express them in mathematical form and they hold value even after the special theory of relativity was discovered and generalized his findings.

But he did start from actual data, may be the famous "falling apple" is just a children story, but there were experiments that he used to both come up with and validate the theory.

I strongly believe that this line of research, trying to take arbitrary (but popular) ML contraptions, and somehow link them to "the brain", without any neurophysiological evidence for delta rule optimization, the bedrock of ML, it's cargo cult science par excellence.

It's also not very new but falls under the old "behaviorist" branch of cognitive pseudosciences popularized by BF Skinner about a hundred years ago. Animal learning and memory doesn't rely on anything remotely similar to reinforcement learning, gradient descent, backprop and all that stuff from calculus book chapter on function minimization, simply because of energy and time constraints.

This effort lacks the constraints of evidence.
The quality of everything on the XPS laptops is subpar compared to a MBP. Used both in the same year for several months. XPS is a good, even very good laptop. MBP it is not.
The Hot Chips presentation a year ago when the C910 was announced shows it comparable to ARM A73.

https://www.anandtech.com/show/15991/hot-chips-2020-live-blo...

I should have one of the eval boards in mid November and I'll be able to do real-word tests then.

The C906 is a little bit faster than a Raspberry Pi Zero, except it has a fairly useful vector unit which can double or triple the speed of many things.

I published memcpy and strcpy benchmarks on Nezha six months ago:

https://hoult.org/d1_memcpy.txt
https://hoult.org/d1_strcpy.txt

I also have results for it in my primes benchmark. It beats out a U54 at the same clock speed and is not far off the higher clocked A53 in a Pi 3.

https://hoult.org/primes.txt

The current "Nezha" board at $99 is obviously expensive compared to a Pi Zero. SiPeed are promising a board with with same D1 SoC with 512 MB RAM for under $20 within the next month.

https://twitter.com/SipeedIO/status/1443486484112183298

The C906 is very comparable to SiFive U54 (as in the HiFive Unleashed, and the Microsemi "Icicle" FPGA) except it has a vector unit and a much better DRAM interface than the FU540 had. But the D1 is only single core.

The C910 is comparable to the SiFive U84, which has not yet been seen in public in actual silicon.

>>Many of us went over to PHP which is vibrant, keeps getting faster and better and is as practical as Perl was and hasn’t stalled.

Who uses php these days?

I haven't heard any one start a new php project in years. Ruby seems to have gone the same way.

Python seems to have won the backend game, which actually makes sense as Python today is bloated like how Perl was once. And these days it feels like Perl with tab indentation. No wonder it fanatic following these days.

Frontend game is now owned by Node, ReactJS, JS etc.

Who uses php to do anything? In fact I don't know of a single college kid I've hired who has even looked at php let alone used it.
He can publish his work, only not the quotations and illustrations from the original Pooh. And since his work AIUI is direct commentary on them the quotations may well be "fair use", so in the end perhaps the only thing he can't publish are the illlustrations. (IANAL, etc.)
Is this a fact or a theory
> maybe because a significant subset of HN audience consists of outliers like Robbe himself and empathize with folks like him easily.

I am one of those people. I knew YUI as a kid, I logged into those KPN computers too. I'd always thought he'd moved on, I never found out about his death until now, or perhaps someone told me and I assumed they were kidding. Now, I can't help but wonder how many other friends who I thought to be retired are actually dead?

Despite - or perhaps because of - my experiences I couldn't help but agree with you more. I found it deeply disturbing to see all the comments here berating his grieving family for wondering if they'd made a mistake letting him on the computer.

I know my parents must have thought the same every time the cops came to our home, they would've been entirely justified in that.

I turned out okay, but as far as I can tell most of us didn't.

low power usage mobile stuff which still packs some processing power.
ASCII only is not appropriate in some locales, as the keyboards don't have a-z. This is why in Thailand people tend to use their mobile phone number as their password, because it can be typed on all the common keyboard layouts they will encounter.

Also, with Windows 10 users will often not even choose their username. It gets generated from their given name + surname (which is a whole different issue for people without one or t'other).

Honestly, the thing that's burns me out about this industry is none of these points. It's interviews. Specifically, algorithm interviews. The higher the level I've had, the more abstract of problem people think they're entitled to throw at me. I've played connect-4, I've had to write out binary search, I've had to pop from and push to stacks until my eyes turned blue all because... This somehow exemplifies a bar?

To be clear, I work on SDKs, CLIs, and mostly server infrastructure components (daemons, schedulers, etc). I know problems within my domain well, and as a result I can model for them well. Take me out of that, and I have exponential diminishing returns. On top of that, I'm not a college grad. I'm self taught. I didn't see these problems near as much as college grads do, so solving them in 30 minutes or an hour is like filing my teeth down without a numbing agent.

Anyway, I am getting out of this industry and taking the money I've made to go into EE. Maybe these notes will help make someone make their interviewing or promotion process better though.
I'd suggest that if you're seeing a steady stream of clickbait articles like this you may be in the wrong neighborhoods of the internet.

Must've been very recent. A bunch of former Obama staffers tried to run a fake Facebook coup in Bolivia just a couple of years ago.

Knowledge does not protect against illusory truth
I think "the big bang" has a problem of changing meaning. Here's my understanding:

- Naïve extrapolation of GR backwards in time results in a singularity at a finite point in time. Call that the big bang singularity (at t = 0)

- Using current accepted theory, we're able to simulate what was going on at t > 10^-32 or so. Before this, the implied densities and temperature are beyond what our theories can handle and we're less confident about how we got to that point (with an excess of baryons, smooth distribution of energy and matter, and the other parameters that obtain in our current universe).

- Inflation is one of the favored explanations for what happened before, but it doesn't address its own cause ("what happened before inflation?"). There's a theory of "eternal inflation" (local regions that have stopped inflating surrounded by regions that are still inflating), which explains the fine-tuning problem (each region that has stopped inflating can have its own fine structure etc). This is less accepted, maybe this is what you're thinking of?

- There's a push to redefine "the big bang" as all the stuff we can explain with current physics, i.e. as starting after inflation (but still using t=0 at the big bang singularity everyone's pretty sure doesn't actually exist). Or maybe it's been like that for a while and it's just pop science that perpetuates the big bang = singularity idea. Like how relativistic mass has fallen out of favor as a concept.
Hydrogen will not be a threat to any electric personal vehicle simply because it’s 3x less efficient (electrolyze water to split it) and thus 3x more expensive to run.
+1 on not looking at the keyboard. It was hard for me so I went a bit further and learned to touch type Dvorak instead. I practiced on https://learn.dvorak.nl for a few months, and tried using Dvorak for low stakes/low speed typing. After 6 months I went to using Dvorak full time. My typing speed is actually the same/slightly better, but it's so much better for writing/coding as I don't interrupt my train of thought by looking at the keyboard.

The tech isn't absurdly hard, I'm sure Toyota has the engineering resources to make do.

The materials are hard to come by, and the manufacturing expertise to be flexible about chips seems to be unique to Tesla so far.

Of course, the engineering effort to make a decent EV is significant, as we saw from James Dyson.
I am hoping modern intuitionism and multi-foundational math (think Andrej Bauer) can finally mend the platonism aristotlism divide.
Yeesh, the ignorance of the folks in those threads. Painful.

Anyways, if someone can't get to non-v6 resources, they have bigger problems than not being able to use DDG. There is a single class of operator for whom v6 deployment actually makes sense, which is large-scale ISPs for whom CGNAT presents an onerous burden on their reporting/monitoring requirements to law enforcement.

Everyone else is just rolling v6 out to meet the requirement of a client (typically government) contract. It's purely additive complexity and for most people, doesn't actually solve any problems they really have.
Reddit, with its terrible interface design, frustrating dark patterns, aggressive censorship, and clique of high powered mods is just as toxic and bad for the Internet as Twitter. I don’t know how they have avoided the fate of Digg but I keep hoping for them to be replaced by something better.
Macs are still a relatively small (but profitable) chunk of the computing world. The ground Intel has lost in desktop and mobile is more than made up for by their utter dominance in server. Intel also has a lot of plays that should bear fruit in holding or retaking ground on consumer compute in the next few years:

1) Arc GPUs. Looks like they will be seriously disruptive.

2) Hedging their process node bets by using TSMC too. The only magic in the wins AMD and Apple have had the last few years have been in them being effectively a manufacturing process node ahead of Intel.

3) Intel will likely be first to market with getting a large set of on-package memory that serves as a bridge between CPU cache and DRAM in terms of latency. Think 8GB+

I am no Intel partisan. My core interest is actually more in seeing performant, open (that is, blob-free [1][2]) hardware. RISC-V and Power10 [3][4] are what I am looking at in that regard.

I expect the reports of Intel's impending descent to be largely exaggerated. Still, it is good drama to fuel a hearty compute war. That is to the benefit of all, so have at it.

This is akin to saying "most of the pillaging in history happened by people besides vikings, so you can't really attribute that to them." Yes, others colonized the areas. The Vikings also did during the Viking age.
To be frank, you sound pretty ignorant with this comment. I'm sure you didn't intend such but any modern perspective puts weed as a safer alternative to alcohol and a social indulgence used by many extremely successful people. This also ignores all of the medical uses which alone make it worth studying.
I'm not a fan of secret work like that. It can definitely depend on the size and composition of the team, though (and the size of the fix / improvement). Once a team gets sufficiently large, people going rogue with side projects like that can cause more harm than good, in my experience. Hurt feelings / resentment, because somebody else had already planned to fix that issue ("why didn't you just bring it up so we could discuss it first?"). It conflicts with some new feature another team is working on ("if we knew you were working on this, we would have done things differently; let us know next time"). Multiple people might decide to tackle the same problem concurrently, without knowing others are doing the same. You misunderstood something fundamental or lack some context that invalidates the entire solution that could have been cleared up by discussing it with the team first.

And then maybe the biggest problem is the whole "putting in extra voluntary work" thing. Higher risk of burnout because you're spinning too many side project plates. Either your main work gets impacted, you start putting in overtime, or management starts thinking they're not giving you enough work, if you have all this time to do side stuff.

I'm having the weirdest problem with my old PS3.. the HDMI chip got overloaded in some manner and I can't get it to connect to my monitor anymore. My monitor is fine with everything else, but on the PS3 it is just a black screen. Weirdly, I can get it to generate a signal that will display on the monitor briefly up to a certain point but not after. I put in a different drive and get initial setup screens, so the video circuitry and cpu still work, but after the setup part gets to the video setup or something it goes black. I need to find a tv with component video so I can find out if the unit will boot on component and maybe reset something in memory to get hdmi working again properly, or if there's some kind of chip that is burnt out and won't let hdmi run after power on.
How easy is it for someone handy to set up? Can the home hobbyist install a hydrogen refueling system in their garage with some panels up on the roof? (related: Does conduit handle hydrogen at 10,000psi or do I have to build it out of black iron?)
Made me wonder what Scoble’s on about these days. This was his latest obsession last time I looked.
Most methods are poor. PRs and commits can easily be gamed and generally the best developers are the ones with succinct small changes that deliver high value.

Two ways I have found to measure a developer's productivity are...

1. Based on the feedback of their peers. It helps to know the team members and the team's dynamics though.

2. Based on the $$$ the team bring in. Depending on how the team operate this could be far from their control though, a lot of decisions about the product will be out of the developer's hands.
Ah, gotcha, found it now. Sorry, I'd missed that, and was thoroughly confused by the pseudonym.

GTK is currently the only realistic choice for a (somewhat) modern desktop toolkit for Linux written in C. There's still a lot of C programs and programmers out there.

For me it's also one of the better options for a Linux toolkit with decent Rust bindings. The Rust-native toolkits aren't quite there yet, but I'm watching this page: https://www.areweguiyet.com/
> Exactly the same feeling - even on Windows there really isn't anything like it - even from Microsoft.

WinForms itself is still around to this day, and Microsoft is actively updating and supporting it on the latest .NET versions. You can just pretend that none of that other stuff ever happened. I've been writing WinForms apps for 20 years, since the initial Visual Studio .NET beta. It still has that same high level of productivity that Visual Basic did.
I think a lot of pro cannabis people are out of balance with viewing the negative side effects. It's a drug and has side-effects. It's much safer than tobacco and alcohol but it certainly has side effects including a strong psychological addiction potential.

Not sure I agree, the drug manufacturing is not equal drug manufacturing. Production of a small molecule therapeutic (e.g. Remdesivir) requires very different capabilities of biotherapeutic manufacturing (e.g. antibodies). mRNA manufacturing is a different beast alltogether.

Possible. In fact a company called LAVO is building a home hydrogen battery for energy storage. Although compressing it to 10,000 psi at home is not quite ready yet, although companies are working on it.
I'm not saying it's a good idea (even though I stupidly do it), I'm merely pointing out that there are reasons that U0080+ may end up in a username; for reasons other than intentionally putting it in there.

As for the benefits, which is completely off-topic, Windows Store is actually pretty awesome if you completely avoid search (and you need to do the Microsoft account thing for it AFAIK). Windows has needed a system to update 3rd-party software, to compete with Linux package managers, and the store is a really good effort (there are still annoying warts that Aur, Deb, RPM do not have). If you're willing to be a bit dumb, there is convenience.
> There's zero impact on full screen apps

How so? Are they going to push full screen apps up to the bottom of the notch? If not, how are you sure it won’t have any impact on so many different apps?

The menubar disappears when you’re in a full screen app, so that won’t help.

I’ve used full screen only for essentially every app daily for the past 10 years on Mac, curious to see how this works out.

I'm in so much agreement, though I would disagree with the last line. I've seen people wave away security concerns because they don't want to be bothered.

Developers waste plenty of time (we're all on here chatting away for one!) but ask someone to even think about security seems to offend them in the way that asking a teenager to clean their bedroom would.
>My second question is why they so naively assume that if a tree is chopped down in 1021 and the same wood appears in a hut, this means that the hut is made in 1021.

I suggest you click through to the Nature article.

The actual article seems to be largely about how the researchers dealt with the exact problem you call out, better than previous work.

It is put front and center as one of the basic difficulties in determining a date. The authors describe how earlier researchers got it wrong, and how they managed to deal with the issue.

As they explain, the term of art is "inbuilt age":

"The term inbuilt age refers to the difference in time between the contextual age of the sample and the time at which the organism died (returned by 14C analysis), which can potentially reach hundreds of years"

Not to be disparaging, but I would like to know what motivates you to write about people refusing to discuss or see the obvious, after choosing not to look at the document in question. Did you really think it would be about something else?

> In CS, most algorithms assume an ASCII character set.

They most certainly do not. E.g., a Turing machine assumes an alphabet Γ which is a set of some characters and is defined no further, as any exact definition is meaningless to the theory. (I.e., the algorithm is generic over any alphabet.) The alphabet need not even be text; e.g., for a Turing machine, the set of all octets suffices.

Even for something like Levenshtein distance, the only real requirement of the algorithm is that the abstract "characters" implement equality testing. For Unicode text, I'd start with graphemes, and then look for counter examples.
If you read that in context, it's clear that the qualification only applies to some of the results they're reporting:

The strongest evidence of cannabis induced alterations in male fertility is in the category of semen parameters. Research supports a role for cannabis in reducing sperm count and concentration, inducing abnormalities in sperm morphology, reducing sperm motility and viability, and inhibiting capacitation and fertilizing capacity. Animal models demonstrate a role for cannabis in testicular atrophy, and reduced libido and sexual function but to our knowledge these results have not yet been replicated in human studies.

"These results" clearly refers to the animal model studies they mention later, so that caveat does not apply to the "strongest evidence" they lead with, about sperm motility and viability, etc. At least not to judge by the abstract.

I like your analogy. But the more accurate statement is that perl has a fraction as many cows as it once had, but still more cows than other not-dead languages. It still gets more daily uploads to CPAN than Haskell gets to hackage.haskell.org packages, for instance.
