I am a computational cognitive neuroscientist, an have worked at many levels. I find each kind of data and model useful to some extent, but I have to admit that the least useful, are, to my mind, those at the detailed neural network level, like the ones discussing in this paper. Somewhat more useful are higher level dynamic architecture models, and, at the highest level, cognitive models, which constrain the behavioral target we are trying to explain. I personally (as one can tell from my other posts here) find the dynamics brain development models to be the most compelling as overall models, but they are not particularly explanatory at the detailed level. Brain science is trying to do the hardest thing you can imagine, that is, explain the most complex machine in the known universe. We persist, but no one entering this field should have very high expectations of near term grand successes.

> Here’s comparative data between M6g and M5, the previous generation instance type

Instead of comparing the 7nm Graviton2 processor against an 14nm Intel processor, I'd like to see its performance compared to an AMD Epyc 2 processor, which would be a more apples-to-apples comparison as both are "7nm" parts. Unfortunately Epyc 2 processors aren't available from AWS yet (but are already announced: https://aws.amazon.com/de/blogs/aws/in-the-works-new-amd-pow...).

Agreed, FPGA would be my go-to solution as well. Although FPGAs certainly can't touch gigahertz+ range yet. Even 500 MHz is... challenging.
Response from the BioJulia developers: https://biojulia.net/post/seq-lang/. High-level points:

* they were able reproduce the performance comparison between Seq and BioJulia

* BioJulia spends most of its time on these benchmarks validating and transcoding data into a more compact, efficient representation of gene sequences

* Seq, on the other hand, operates on the raw ASCII input data and does no validation

* BioJulia devs implemented Julia types that representing gene sequences the same way as Seq does in less than 100 lines of Julia code [1]

* when using the same representation in as Seq, BioJulia was significantly faster than Seq

* BioJulia devs were able to further optimize transcoding of gene sequences to get a 10x performance improvement [2]

* with these improvements BioJulia reaches similar performance to Seq while still doing validation and using less memory

The full post is well worth reading. For me the main takeaway is that there's no real need for a domain-specific language at least not based on these results. Julia is already a great language for this kind of work and you get C-like speed and JIT compilation for free.

I wonder when and how Azure and Google Cloud will compete with AWS in this market.

They could buy ARM processors available in the market, but I doubt they will be able to get them as cheap as AWS who builds their own.
Being from Ohio I knew quite a few farmers, or people that grew up on farms. They all laugh at organic and say it’s bullshit. There is typically no way to tell after the fact if something is or isn’t organic. Same with rBGH free dairy products.

Farmers have known for years that the label is only as good as the word of farmer, and with economic pressures to cheat, it’s not surprising to find cheaters.
Isn't it like saying "if we were to shut up gay sexual relationships"? Because the main way for distribution of HIV is via gay anal sex, so if we close the market why not ban gay sexual relationships?

I started out using Mozilla Communicator Suite, Phoenix, and now Firefox as my primary browser. I never defaulted to IE and never to Chrome but I have always strived to make everything I wrote work across as many browsers as possible.

Something funny happened around IE 10, the HTML, CSS, and JavaScript all started running correctly on the first try on all browsers, even mobile.

It was glorious for about a year or two then everything started to diverge again and with Mobile versions of browsers we're starting to head back towards the hell that was developing for the Web around 2004.

There are certainly more platforms to juggle today but they're more similar than different at this point.

I can say I daydream all the time too and have been doing it since I was a child.

Hi there, just to clarify, the article is from 2018 and what we're looking at right now is a post re-publish with the "2019" addition. Back then, the main page looked something like that http://web.archive.org/web/20180802025742/https://uploadcare...

Nuclear energy is capital-intensive, but not resource intensive. The cost of the plant dwarves the cost of uranium to run it. In this way, it's similar to wind.

You’re absolutely right; he did say 64 bit. I just wouldn’t do that blindly either, and the author admitted to not being fluent in error analysis. The issue with even doubles is that the magnitude of your error in a running total calculation is a sum of all the errors of your largest intermediate results (the results of multiplies you don’t see or store explicitly). That means with a bank account, the error of your calculations continues to grow forever unless you are explicitly correcting the errors. Rounding does not solve that, so even using doubles for money is a sketchy proposition unless you really know what you’re doing.

For me, Twitter has been the worst thing to happen to journalism. There are a lot of downsides to strong institutions and gatekeeping, but when it comes to journalism I always felt like I was reading The New York Times or The Washington Post and not an individual reporter. The shroud of not getting an up close an personal look put the institution at the forefront.

With social media, Twitter specifically, the journalist becomes the main focal point -- unfortunately the biases comes out as we are all human and you begin to get a closer look at how the sausage is made, how much "access journalism" corrodes coverage, and particularly how non-diverse these institutions are (everyone feels like they went to some Ivy or liberal arts college with somewhat wealthy or well connected in journalism relatives). A majority of the content is still really good (climate reporting, international politics, 'explainers' and data backed reporting are all excellent) from the big institutions but I've totally avoided political and most opinion columns since 2016.
Have you read smolensky's harmonium paper? It's the first restricted Boltzmann Machine -- and I believe elman and smolensky were colleagues with hinton back at UCSD (with rumelhart and Don Norman, et al).

The approach was focused on presymbolic processing -- and tried to optimize harmony. Harmony was, interestingly, the first mathematical model of the mind (by Pythagoreans/platonists in ancient Greece). It has a lot going for it these days, too, to understand oscillatory coupling in neural circuits. I learned recently that brain waves are harmonics (frequency doublings), which somehow I missed before!

In my experience, it's even a bad idea to share immutable data between tests. At least, certain types.

Basically what happens is you write a bunch of tests, and they all operate on a Person let's say. So you get into the habit of making a 20 year old Tom with bla bla bla each time. Very repetitive. So you decide to move Tom into a common file that every test can import. Typical DRY stuff.

Then, over time, Tom grows tentacles. Every test that uses Tom needs just one more little detail to be added. Tom needs to have a height for the height test. For the shopping test Tom needs a walking speed and a preference for ladders. These properties keep accumulating, and Tom grows huge. His growing complexities, and his presence in so many tests, make it impossible to remove or edit anything about him. You resort to making Tom variants. In each test you clone Tom then tweak his weight and shoe type or whatever. Of course nobody is making sure that all these properties and property edits are inter-consistent, and you find that because of this even adding properties to Tom has somehow become difficult. Eventually, understanding all facets of Tom becomes a black art. New tests fail sometimes, and no one knows why. You poke and prod Tom for a couple hours, and the problem goes away. Eventually even basic usage of Tom also becomes a black art.

You should have just repeated yourself.
I care what AWS charges me; I don’t have the energy to care what their underlying cost structure and its constituent parts looks like.
We literally mine Uranium. How can people not realize this stuff can be found naturally on Earth?
> No, we aren’t using computers with logic gates that have 10 discrete states. Even if you’re programming to decimal, the underlying representation is still binary.

That is not the sense of "computers use binary" that justifies the conclusions in the sentence in which the phrase was used in the post being responded to, so while true on its own, in context it is an example of the fallacy of equivocation.
Yeah, bandwidth costs is a thing that turns me off about AWS too and then a bunch of proprietary services too, so then you have to rewrite your application if you used some of them and wanting to move providers. However if you want to move fast and not worrying about some of the behind the scenes and have a budget for it, I can see how some large companies and well funded startups love AWS, even though there's sometimes cheaper and more open options.

True, but the equating of a brain with a city is largely specious, especially when trying to understand cognition. Yes a brain regulates many low level parasympathetic processes. But it's the decision making and memory systems that we most want to understand and replicate in silico. And the coordination of a city of mostly independent self-interested humans is a poor analogue for the biological bases for a coherent thought process, unless it's only the medulla or pons that we hope to model.
Oh please. Your slippery slope argument is garbage. The truth is, only ~33% of 4 year-olds even attend preschool in the US [1]. So by the facts of reality, preschool is completely optional. Plenty of people go on to get college degrees without going to pre-school and it's ridiculous to claim it's the same as skipping high school.

Speaking of college... Unlike for real teachers, only half of public preschool programs require any sort of degree or qualification, and this guy works for a private preschool, which often have no requirements at all.

Indeed, after a difficult search, I found that he actually never finished college [2]. So yeah, he's basically just a random guy with no official background in education. So who the fuck cares about his opinion about STEM in education?

He got the job because his daughter went to the preschool. That's it. That's not a qualification.

I find your defense of the institutional practice to be deliberately obtuse because it focuses on the rose-colored glass elements while ignoring the negatives in an attempt to gloss over the commercialism, colonialism, and other troubling aspects of Mormon corporate policy. I'll not comment further on the matter. Thank you for engaging.
I took a cursory look at the crypto on the backend, and it was mildly concerning. It appears to not be using modern asymmetric primitives. At first glance, it's not insecure or anything... just old[0].

Rather than using something like libsodium's public-key box API, which is wonderful, it's using a 2048-bit Diffie-Hellman Prime group. This isn't really great. You should definitely upgrade to more modern primitives. I can highly suggest libsodium as a drop-in replacement.

The other thing about this that's more concerning is that I have no idea if there is any validation going on to prevent small subgroup confinement attacks on this, but I don't really want to spend anymore free time checking this out and I'll leave it as an exercise for the reader/author.

Personally, I wouldn't use this product until a few cryptography design decisions were changed. If you're marketing this as a privacy-centric product, there's a lot of work to be done--not just on the Diffie-Hellman usage.

I do not know the answer to your question but the way I solve that problem in osx is using quicksilver and triggers. You can give each app or really any quicksilver command a hotkey to switch to it directly or start it and switch if it's not running. I couldn't live without it. I have hotkeys for all my commonly used apps and generally never launch or switch apps any other way. I also have hotkeys for manual tiling to the corners, sides, center, and full screen so I don't need to use the gui for that. The fact that this isn't doable out of the box makes me question if either Apple or Microsoft has ever considered hiring a single ux expert.

On Linux I use jumpapp for the same functionality.

All I've seen in your posts is a defense that ethics and standards don't matter because the economics don't make sense. At the end of the day you have a choice of whether or not to be a journalist or to do something else entirely.

If you're doing it for the love at that point, then it's not about the money and no argument can trump ethics and standards there. I think journalists spend so much time reflecting on others that there is little to no self-reflection. Just because your boss asks you to do something stupid, doesn't make it okay to do it.

If you're a soldier in the military and you carry out an unethical, illegal order, you're not only still going to get tried for it but you have the legal right to deny that order. And that's a job where you're already expected to maybe kill people for your government.

But while I'm glad that the military holds higher standards of ethics than most of the rest of us, the job of a journalist can be one with the potential to lead men to war. Ethics are just as important in your job is just as it is in theirs. Your tools are just as powerful and can equally be used as weapons.
> What we need is a Newtonian model of the brain.

This seems like an odd take on Newton to me. What made his contributions important is that they were correct up to the precision we could measure for centuries.

We are nowhere near that for a subject like neuroscience.

There have been models adopted by scientests who at the time knew they were wrong and incomplete. For example ancient astronomy or medicine or logic. but their adherents tended to hold back science when new discoveries were made. So they are double edged swords.
This looks awesome! I have a brother-in-law who is 15 (gosh he's getting so old) and who is frighteningly intelligent. He spends most of his free time hooking up relays to a raspberry pi to control an array of Christmas lights. I'll forward this repo to him; I've been trying to get him to start experimenting with Racket. This might just be the ticket.

I think Racket is a wonderful language for education, and this library will certainly help a lot more kids find interest in learning Racket. When I first started programming, I wrote a lot of games with ASCII art in Perl. They were not fast, but I learned a bunch! If I had had this, I would have picked up a LISP much sooner.
There might be benefit from some of the extra bits available (the specific GPU in Mac Pro is not exactly easy to replicate elsewhere as it's a custom twin GPU setup with extra bus for cooperation with another unit if necessary) + the FPGA codec card that might be exploited by the stuff he does for work.

Replacing a software-only codec with hw accelerator card would go a long way to explain performance difference.
Allowing one megacorp after another buying out their competitors is certainly a failure by lawmakers. Such behavior used to be plainly illegal.

Yes, in "you can't play 20 questions with nature", Alan newell advocated for computational "unified models" of cognition. But they were heavily symbolic. While useful, they don't really make it more understandable. (That's my experience with act-r, anyway! It's useful, but doesn't give big picture synthesis, like a Newtonian model might. It's a lot of little models.)
