Forecasting real-world complex networks' robustness to node attack (2023)
Pre-mature optimization and over-engineering are a greater issue than the opposite.

Generally, clever architecture at the right stages can beat clever code and leave flexibility to pivot.

That fan stays idle on low loads, and if you wanted you could also leave it unplugged to just rely on the heatsink.

Then again, N100 can also be bought with passive cooling. But not so sure how the mini PCs of the article would fare without a fan.

Hey. It's nothing very fancy. About 150 lines of C/CUDA code with no deps, including args parsing and logging.

The code runs at steady rate of 18.00-18.40 GH/s at cloud GPU. In fact it's not hashes-per-second, but actually messages-per-second checked.

It launches a 64⁶ kernels in a loop, where each launch checks first two bytes of the SHA of a message concatenated with unique 6-byte nonce per kernel + 6-byte incremental nonce for each launch. There is only one block, so SHA algorithm is heavily trimmed. Also, most of the message is hard-coded, so pre-calculated SHA state is used; it's 10 loops less than needed to encode whole block. Since we only 2 bytes of the hash to check, last two loops also unrolled by hand to exclude parts that we wouldn't need. All code also in big-endian since SHA is, so message hardcoded in big-endian as well.

Base64-encoding is pretty time-consuming, so I've optimized it a bit by reordering the alphabet to be in ASCII-ascending order. I've got to the point where single binary-op optimization can earn 100-500 MH/s speed-up, and I don't really know what else here is remaining.

I don't have RTX4090, so instead I just rented 4090 GPU to run code on. It's less than $0.3 per hour.

I've tried GPT-4 to get some directions for optimization, but every single proposal was useless or straight wrong.

I by no means a C/GPU programmer, so probably it can be optimized much more by someone who more knowledgeable of CUDA.

GPU's are ridiculously fast. It freaks me out that I can compute >18,000,000,000 non-trivial function calls per second.

Anyways, if you want to chat, my e-mail is in the profile.

And re the original topic, that thread has a reference to a 2.7GHz active probe for $226!

This is timely, after not getting my Orange pi to boot an image, I saw I can get an actual mini PC like these used on eBay for like $60 shipped. 8GB ram and 500gb SSD with small form factor. I'm considering buying more and trying to host some old school LAN parties as used LCD monitors can also be had for about $50.
Humans have been thinking for millenia about animal consciousness and how to ethically treat other beings. To wit, the Jain principle describing animal consciousness:

https://en.wikipedia.org/wiki/Ahimsa_in_Jainism#Overview
I really disagree with the quote at the end `just a few people are going to miss the smartest in the room, but everyone is going to miss someone kind.`
This is true if the smartest person in the room is a jerk, but I don't find that to often be the case. In every group I've worked in, the smartest, most talented people are often _also_ confident in their abilities to the point where they don't have to _prove_ it to anyone. They help the team succeed.
The people I am never sorry to see go are the insecure people with a chip on their shoulder who constantly try to prove that they are the smartest, most talented person in the room. They often are not.

The kind or nice person, sure if they are some kind of glue to the team that helps the entire group work together, they don't need to be the highest performers. But incompetent nice people also are a problem.

These conversations around the rPi make no sense to me. To me the value of rPi has always been:

* Simple to install a well supported OS with a full UI.
* GPIO array (including pwm, i2c, etc)

I could take one. Connect a keyboard and monitor. Jumper a few pins into a breadboard with an LED matrix, and right a python script to bitbang a multiplexed LED array

The only other product I have seen that I view as even competing in the same space is the OrangePi line. However, those are vastly inferior in terms of support.
Yeah, I don't think it should be required, but I think policies banning managers from writing letters are also wrong.

I checked Digi-Key through RPiLocator and they report several thousand units in stock each of the Raspberry Pi 4 2GB at $45 and of the Raspberry Pi 3B+ 1GB at $35: https://rpilocator.com/?vendor=digikeyus

For those unfamiliar with them, Digi-Key is a electronic components supplier to manufacturers but they also sell to individuals. Their stock count should be accurate.
Python scripting based only on the standard library is underrated. There is no pip hell, it's readable and maintainable by the most junior team members, it's largely cross platform. This is the "batteries included" dream.

It's both.

The game started as a side project that went crazy viral as the first real way people could access an LLM (GPT-2 at the time). That of course immediately led to people using it for NSFW content, and they were really the first project to have to deal with the question of what to do about that content. Their initial reaction was to deploy a filter, which worked but was unpopular with many in their early audience.

I haven't followed the project for a while, but my understanding was that they rolled back the filter at least for paid accounts. But when they had the filter it wasn't just an OpenAI restriction because their filter actually predated GPT-3 and OpenAI's APIs.
I read his “The Reefs of Earth” a few years back and it blew my mind. Such an interesting book.

I have a Pi 4.

It runs home assistant and bunch of other docker images.

It has a DVBT-2 hat that feeds tvheadend that lets me watch broadcast TV on my laptop and phone.

It doesnt make a noise. It doesnt reboot randomly. It doesnt get hot. It doesnt get hacked.

After that, who cares?

Doesn't matter. Even if you have no right to be annoying, being annoying doesn't justify punching you in the face. Even if you have no right to kill 100 people, killing 100 people still doesn't justify killing 50000 people. Even if you have no right to watch sportsball, watching sportsball doesn't justify shutting down the Internet.

Ugh everything is "dropped" now. This one really gets under my skin.
I'm starting to wonder if we're seeing the ramping up of an Arm vs. Intel war at the same level as Mac vs. Windows, or emacs vs. vi, with Raspberry Pi as a convenient proxy, and all the usual foibles of every other us vs. them war.

It wouldn't surprise me if paid influencers were fanning the flames, either; certain folks have a lot to lose if arm goes mainstream on the desktop.

And then there's the recent Raspberry P-IPO or whatever it was, which seems to have pissed a bunch of people off...

The timing is interesting.

I can see the appeal of the N100 and similar -- and am currently considering one -- but it's hard to beat the ~1W DNS/DHCP/Consul servers that have been humming away in this house trouble free for the last decade...

I don't need those to power my homelab. There's a reason they're separate, and tiny low-power Pi's are ideal for that job.

I have in my possession more than merely a hammer. :)
Basically all open source licenses have a clause requiring attribution. If people copy your work and remove your name and claim it's their own, you can DMCA or sue them just the same whether you made it open source or not.
Managers and supervisors are not protected by the NLRA, so whether they might like to provide a reference isn't really a matter of concern for the NLRB. (In practice, managers provide references informally all the time, and I can't imagine a company actually taking action against them for that unless the reference causes some huge problem.)
If you're interested in the computers on the Voyager probes, this talk was really good: "Uptime 15,364 days" https://www.youtube.com/watch?v=H62hZJVqs2o
same as humidifiers and they make bacteriostatic additives that help control this (although eventually it does need to be cleaned regardless).
Compared to an x86 PC which is what TFA is showing ? The only argument in favour of the RPi is GPIOs, but "simple to install" and "support" definitely are a thousand times better on standard x86 PCs than on any of these ARM SBCs.
Plenty of PIs in labs of hardware tech companies. Very convenient when you need a small linux box, indeed, or when you need to access a piece of equipment over a serial terminal, et.c
Based on the article, it seems that this could be reasonable to pursue. You don't need to break a law for a lawsuit, just show damages resulting from another's actions. If you convince the NLRB or a jury that not providing references suppress your ability to get a job or increase your salary at the next job, that could be all that is needed. But this would be applicable to laws on anticompetitive behavior, but that's more of an NLRB thing.
Let's keep talking about this. How is two years "several"? That's "a couple" literally and maybe "a few"
This is a bad article only meant to market the book. Almost 0 information in this, actually impressive.
Have you tried any devices that claim that they reduce noise from power sources, for example the Tripp Lite (now Eaton) Isobar? Or a active UPS?

Neither of these cheap solutions though?

I think a lot of people don't realize that there was a decent size, but small market for SBCs for low-volume embedded work (including hobbyists) before Raspberry Pi. You could get a lot of different kinds of boards with good Linux support and a not terrible price. Often, a processor vendor would explicitly provide support for these things because it was a good vector for selling chips.

Broadcom, having never wanted anything to do with this market since volumes were too low, had an abundance of a CPU SKU that was good for this. So some broadcom engineers founded Raspberry Pi to use up this excess stock, essentially getting these chips for free. The original RPi blew every other SBC out of the water on price performance (and many manufacturers out of the market) because by getting the most expensive component for free, they could sell Pis for an extremely low price. It also massively expanded the market for SBCs, as hobbyists flooded in to work with RPis.

5-10 years ago, the sweetheart deal with Broadcom went away. Now Raspberry Pi has to compete with everyone else for Broadcom SoCs, and during the semiconductor shortage of 2020, Broadcom had tremendous leverage. Now, Raspberry Pi pricing is nothing special, but they still have the brand name and they have captured the community (on the back of behavior that was borderline anticompetitive).
You forgot the biggest benefits to the company - increased retention rates and salary suppression.
I think unmentioned is that this is the east coast style. In Seattle we just let you sit there indefinitely because honking wouldn’t be “nice”.
Yes of course but this was just to validate the hypothesis that FMs and their tokenizers can generalize on a fully encrypted dataset.

Now that the approach is clearly viable, I am going to extend it to use a modern cipher like XChacha20 which is a gold standard.

You seem to think we're somehow "empathetic by default", but that's something I'd disagree with.

Our primal instinct is one of tribalism and auto-centrism, but over long periods of time we've developed a (fragile) capacity to empathize with 1) other people that look like us, and 2) other people that don't look like us, and 3) perhaps animals. But we didn't always have this capacity, and we see it break down all the time.
Thanks! If you don't mind some more detail

- how much does it go into people and personalities of the team and stakeholders, besides the technical design of the game?

- it sounds like first part of the book is historical and talks about various games, second focuses strictly on simcity?

- does it only cover first simcity? What about latter generations and competitors, or maxis follow ups like simearth etc?

Thx muchly!:)
In the past I have experimented with pointerrawupdate and desynchronized, and I was unable to reproduce any latency benefit in practice. These features have a lot of caveats and are not reliable, in my experience, which is probably why practically nobody uses them. It's way too easy to fall off the fast path, if the fast path is even supported on your platform at all.

Also, native apps have a lot of options to reduce latency without any risk of tearing artifacts, and it's unfortunate that web apps don't have access to those options. The web has a long way to go to match native on the latency front and there really hasn't been meaningful progress in that direction.

I would like to experiment with pointerrawupdate and desynchronized again. But I'm currently relying on Emscripten's SDL implementation for input and drawing, and replacing or modifying that is daunting. After all, this is just a fun side project for me.

A much easier and more widely supported latency fix would be to use a blocking API like WebGL's ReadPixels to synchronize the content process and GPU process and defeat the deep frame pipelining that the browser usually falls into, at some cost to performance. I plan to try that first.
> The Clojure/JVM statistics/scientific computing/now tensor math packages just never got as good as Python, and in Smalltalk they were a non-starter.

There are undergoing efforts to improve numerics performance on Smalltalk. Pharo, for example, uses JIT, and already beats pure Python. But numerics in Python is mostly outsourced to fast modules written in C/Fortran. So people are in process of making Pharo's counterpart to NumPy/SciPy (PolyMath) leverage BLAS/LAPACK integration as well. See:

Diesel used to be cheaper. I had a car with a 1.1 litre diesel engine and I would get 60mpg (uk gallons).

Now electricity is much cheaper, around a quarter of the price as long as you can charge at home.
I tried to look it up but I am still not sure if this book discusses SimCity's programming or not.
You need 3 things to make a sale:

1. Why anything?
2. Why this?
3. Why now?

Sure FOMO is one of your tools, but I suspect it's overused. Consider the classic "This price won't be around for long!" move alone.
I have a home server that stores and processes all my photos, using PhotoPrism. Things like face recognition does require a bit of a compute. A NUC is perfect for this use case.
Just to add- not easily defeated. I am even hosting a bounty for whoever can break this one (the model weights and tokenizer are available on huggingface) :D
In this market, "cheap" is often comparative to performance. You can now get better capabilities for the same price.
Sure. I haven't looked at the code so I could easily be off base but, even with floats I want to delay that divide for as long as possible
> kind of really important code maintenance that Xorg would need

What maintenance is actually needed for Xorg?
Also check your USB cables if they're supplying power. Low-quality cables are notorious causes of instability with older Pi's, and I doubt the 5 is any different in that respect.
Existing power generators have deprecation schedules measured in the decades. The free market forces are going to prevent those investments from becoming a write off today.
> It is much cheaper, safer, and less fragile to just block everything and force customers to the isp own servers.

Sure, that's common too. But that also precludes you from running your own recursive resolver to circumvent their blocks.
Five Nine Problems
>You can’t calculate derivative of a discrete function.

Every integrable function has a weak/strong derivative.
I assume he's talking about an agent model from his description, in which case it is exactly trying to derive the macro economy from the micro decisions.

This is a very classical approach. The idea that macro economy follows different models than the micro is somewhat modern. For example this caused a huge crisis in Keynesian economics in the 1970s where inflation models and the Phillips curve were drastically different than predictions and was a factor in the development of New Keynesian theories.

The examples you give aren't about individual micro prediction not agreeing with the macro, but that's the case you can come across in various economic theories where is there is a literal disconnect the two and correct micro equations disagree with the macro equations.

LyX is fantastic. There's no way I would go back to hand writing LaTeX after using that. The formula editor is especially good. Forget about any terrible WYSIWYG experiences from Word. It isn't like that.

That said, I would only really use it if I had to produce some LaTeX, i.e. if I was writing a paper that I wanted published.

For just writing stuff I think it's better to use Markdown or Asciidoc with Katex for equations if you need it. Then you can target the web.
Find another payment processor. Stop blaming others for your lack of contracts.
That's so remarkably stupid for travel insurance, it's unbelievable.
But what does that actually accomplish?
You can have full-size desktop PCs (large mobos, large GPU, multiple SSDs, fancy power supply) that idle at 20W.
The catch however is that this can cause (relatively) high resistive loading, so isn't really suitable for all applications.
>Most sales, especially within IT, is about trust.

Our CIO ordered us to switch away from VMware when Broadcom made changes to the licenses. We are a mid-sized company with 1500+ employees. If I remember correctly, Broadcom anticipated some customers would switch away, but they could still profit more from their larger customers.

My friend works at a bank. They switched from Azure to Google Cloud because Microsoft's prices "didn't make sense" to them.

Maybe just ban advertising altogether.
I Blame Myself
PayPal for small businesses is absolutely terrible, terrible reviews on trustpilot, and terrible first hand experience, all this in mind I still kept going on with PayPal Business..

I signed up, verified my identification, 3 weeks of payments go by, they block funds from going to my main wallet, fine, I thousands in payments come in within these 3 weeks, I have no NSFW business so I assume I'm in good standing with PayPal, but behold an issue, they permanent block me... for what I'm trying to wrap my head around, I spoke to support, they say it's because of one of these 3 things or more

1. inconsistent log in location
2. too much chargeback or disputes
3. same email on multiple accounts

Inconsistent log in location, so can someone not travel and log into their business account? or can someone not use a VPN? how does this warrant closure of a business account? I tell them exactly this and also note that it shouldn't really matter, I use my mobile that I registered on to log in, I use my computer, I use any device with a connection to log in and check regularly, the response is "Well there is high cases of people stealing phones" ... lol what?? so what does that have to do with me? this can't be a me issue if out of 29,000 reviews there are more 1 star reviews than 5 stars https://uk.trustpilot.com/review/www.paypal.com

They tell me about the second reason amongst other things, and I'm also confused, because out of the many customers, only 1 disputed and that is only because they was charged 2x accidentally, I refuned them on the same day, so why would I get punished for that???

they can see the proof on my account, they say that I have lots of customer disputing, clearly lying to my face, like i'm an idiot, the customer ended up purchasing again anyways as it was a mistake to double charge on his end

Last possible reason was same email, multiple accounts, I have a business and personal account ... what metric are they using to know this?? if it's IP based then its flawed, I have many people in my house with paypal, I just fail to understand how someone can use PayPal for 3 weeks, on a verified account, with verified bank information, phone number, etc and get closed only AFTER you make money, it seems like payment processors do this on purpose to make money and close businesses down...

Anyways this was a rant, I've appealed 2x, i'm hoping they make the right decision and let me do my business, if not it's fine, I will be the 1 out of 29,000+ bad reviews that will swear to never use paypal for business again, i did this post just to let some steam off, this is annoying
If your server is on the internet with a public ssh server then it is probably providing some sort of internet service. That internet service is almost always easier to DoS than your openSSH server. If you are not providing a internet service then why is your SSH open to the internet?
I suspect a lot of the current disdain is a product of function creep. While the original Raspberry Pi was used as a desktop and server, people understood its limitations. Now that many of the limitations have diminished, to the point where you can expect reasonable performance as a desktop and use it as something more than a simple web server, people are justifiably comparing it to alternatives (which have come down in price over the same period of time).

Of course, the Pi is also facing competition from higher end microcontroller based solutions. People seem to forget that there was a time when hobbyists bought the Pi for "Internet of Things" like projects, both due to its cost and size. Then came the ESP8266 and ESP32 and development boards that packaged both a microcontroller and network interface.
Good initiative. Now people need to go through this and do the reviews :-)

Next step would be to do reproducible builds (if it's not already the case).
Binary Fuse Filters: fast and smaller than XOR filters
If there’s one single business that I might expect to honor traffic from foreign countries, it would be the travel industry. I can suddenly envision using a VPN to route through Asia and check a travel agent’s site access before purchasing.
The features he's talking about were added to Chrome for ChromeOS/Win8 tablet stylus drawing support, which they refer to as "inking". They're kind of a specific fast path for that use case. They were not tested for any other use case and as a result tend not to be usable in practice due to various caveats, unfortunately.
