For some perspective, in ~2006 I had satellite internet. We had a rolling 30 day window for 8gb of bandwidth.
Simple, you just allocate a bigger contiguous chunk of memory and copy the entire vector over when the current chunk maxes out.

This is fun, I do haptics for a living and I would have never expected to have something to say here.

The way around the seat shaking problem is to use wideband vibrotactile actuators tuned to respond between 10 and 250 Hz on different part of the body. They can be embedded is seat or on a vest.

The mechanical energy transfer is local, can be tuned individually, and consumes much less energy.

There are also several successful products leveraging this principle like the Razer Hypersense line, feel belt, and others.

A recent company acquired by Meta, Lofelt, started their tech doing exactly this.

If you want to jump into the haptics rabbit hole, I animate a podcast [0] with some industry folks. Fascinating topics.

I wonder if Fadell is similar in his own way, from what it sounds like, Nest was a very top-down, stringent environment, which is why it didn't play well with the more open and casual Google after acquisition.
Ostensibly the parties are choosing select people through a strict vetting process. I think informing yourself about individuals would be much more difficult than picking a party with a long, presumably representative history.

There's also a considerable barrier to entry. Louis Rossmann had Larry Sharpe on, who had an interesting talking points in the first three minutes:

I think the key point is that the media wouldn't cover him if he didn't buy ads, and the cost of a poll stood at $40,000. How far can you campaign on a shoestring budget? It's a little easier when you can pool resources through an institution or a party while also gaining the immense benefit of a much more robust network of connections.

Those are some of the infrastructural barriers we've got to overcome, and I can't imagine that movement in that direction would go uncontested. It's quite the uphill battle.

I found it fascinating seeing archival footage of an idealistic startup too early to market, where he appeared to be the youngest and least experienced on the team.
It depends on what your definition of success is and where you're hired. There are plenty of books describing the way that each of the big tech companies work. Also plenty of books on how to get promoted to say a management position.
Agreed. Totally insane - you might as well have the stock exchanges fold up and go home. What's the point in raising money in the capital markets if you are going to be subject to such silly lawsuits. Hopefully this will be thrown out quickly in the courts.
Apple's M1 has a data dependent prefetcher (superset form of pointer chase prefetcher), as discovered by the researchers behind the Augury paper [1]. They discuss how it works, how and when it activates, as well as a couple other cool details which should more than answer your curiosity. They don't have benchmarks for performance, but these sorts of prefetchers do exist (and possible in hardware you're using right now!).

Web coder looking for business friends in New Zealand
Hello world,

I do web development here in Auckland. I do not have a full time job at the moment. I am not the smartest person but i do have a good heart.

I am looking for business friends to build web project ideas using the best technology possible.

Please message
Email : mustafa@web-tech-company.com or comment here.

I to hear from you.

10 Euros for a ~gigabit? That's crazy! In 20 years that's only 200 Euros. Even ignoring the cost of procuring the gear and maintaining it and the business for 20 years I'm not even sure how that covers the transit costs for the data during that time.
The alleged harm caused by Meta may have a lot of merit, but the portfolio argument seems insane to me too. This line of reasoning suggests that companies have a fiduciary responsibility to avoid competing too hard against competitors because they share common owners. Anticompetitive effects have already been a concern due to common ownership by index funds [1] and would be exacerbated if this portfolio argument becomes a legal standard.

I should have mentioned that emacs is also a fundamental tool for all of my work. But since everyone, everywhere uses emacs that would be stating the obvious :-)

I tried orgmode. I even attended a course at CMU that used it for the "live notes". It is excellent for teaching. But it has the same flaw as the "live notebook" idea. There is no generally accepted structure to the approach.

Everyone "understands" books. They have a preface, chapters, an index, a bibliography, pictures, credits, and a table of contents. Literate programs leverage that shared understanding of the structure.

Think of a physics textbook. If you just copy every equation out of the book then you "have the code". All the rest is explanation. They belong together so the explanation and equations (code) are intermingled.

I'm a "primitivist". I work in straight text at an emacs buffer in fundamental mode.

The point of my code is to "talk to the machine". The point of my literate program is to "explain to other programmers (mostly 'future' me)". Note that this is NOT DOCUMENTATION. It is explanation, best presented in book form.
Courts can only make orders on parties of lawsuits. It can’t make broad orders against groups of people or non-entities.
For #1 there are a couple great youtube channels that cover a lot of the technical background on drivers and control systems (amplifiers) as well how to objectively compare and test audio setups. 1 - PS audio https://youtube.com/c/PSAudiochannel and 2 - Tech Ingredients https://youtube.com/c/TechIngredients

In this tech Ingredients video they go over some really well performing but very simple and low cost to make speaker and amp set, as well as a test setup to do objective comparison tests on different designs. https://youtu.be/GslJ8Hf4WwE

For #2 I've actually done quite a bit of work with sound and the body, in designing medical devices. It's interesting, sound travels very well through the body, why bone conduction headphones and ultrasound work so well. Most of the good info on sound and it's interaction with the body I've found to be in clinical and scientific papers.

I hope something here helps!
That would be me. I use the electronics but I have some selected paper charts just in case. Saved my bacon once.

Oh, sorry you're shocked and sorry I don't have sympathy for tech workers that have the education, skills and connections to find cushy jobs that pay at the top percentile of wage earners in the U.S.

I'll save my sympathy for the homeless, hungry and bottom percentile earners that work hard at an honest living and scrape by everyday trying to feed their families. Sorry that my sympathy is too limited for you.

"Stupid" is probably the wrong word here. "Gullible" is probably more apt, considering they keep falling for these.
Normally the lawyers in these cases have one of either 2 motives - 1) idealogical (will pursue theses cases to push a political point so as to influence/intimidate others and to develop a political policy down the line) or 2) Financial. And if all things go well they get both done. Whether or not these intentions are good probably depends on whether you think freer markets should be allowed or not. Or whether they should be governed by idealogy pushing the money to one side of the political spectrum or another.

Generally no, that's not true. For example:

Compared to what? What about the docker image? It’s effectively a development environment for math, and it’s seemingly robust. It doesn’t seem particularly wasteful in its use of dependencies specifically has the goal of interfacing with other open source tools. Rolling their own X for everything rather than using the de-facto third party libraries seems like a fine, manageable choice to me.
If it's a contract term it isn't that unreasonable.

If it's a unilateral change it likely isn't legal in many countries.

I searched my emails and it appears it was the Fremont site. It was about 7 years ago I moved off Linode. Initially I went to EC2 but then I just replaced most of my VPS needs with other specific services. FWIW, EC2 was more reliable IME, but obviously the Linode UX was way better.

170 dB is super high, like a shotgun blast or a jet engine close by, or a hurricane.

This video goes into detail on dB ratings. It makes the point that these truck air horns that are labeled 300db on Amazon are actually many thousands of times more powerful than the Krakatoa blast, and would actually expde our planet. Spoiler, the air horn aren't actually 300 dB, they're more like 100-115. https://youtu.be/zAe9qvC49qY
I am quite puzzled, at such scale with low seasonality what are the reasons they haven't moved to their own infra? Managing and hiring people to do so would result in big decrease in cost compared to the cloud.

The best implementations typically have a queue per thread and work stealing. The first threads to finish their assigned work will grab items from other queues, but until then you get perfect cache locality.

Java's queues and global threadpool queues in general are pretty old hat.
Hey, it worked when they brought back Jobs!
It depends on what prefetchers your CPU has and the actual underlying access pattern your accesses cause. If chasing next leads to a constant stride run through the array, you'll get identical performance to that of an iterative walk since essentially every high performance CPU since like 2010 supports stride prediction based on raw addresses. If .next sends you bouncing all over the area, you'll get complicated behavior since whether or not the data can be prefetched depends on the performance/existence of a pointer prefetcher, which is less common/more error prone. We know Apple's M1 have it due to some researchers using it as a side channel [1] but you'll have to do some digging on whether or not your laptop has one. Would make a nice post here if you do make the benchmarks :)

Sure. The sustained wind of a hurricane could be thought of as a 0 Hz 156 dB sound wave. A more ordinary passing breeze, the sort that we consciously recognize as a breeze rather than as a sound, lasts for around 1-10 seconds. So we could just as well describe an ordinary breeze as noise in the .1-1 Hz part of the spectrum somewhere above 100 dB of loudness (guessing).

Alternatively, sound is just a breeze too fast for direct conscious perception.

In a past life I was a developer and software architect. Now I do marketing stuff. I'm looking to join my fourth B2B SaaS startup.

Roles I'm looking for:

CMO, VP Marketing, Head of Marketing, Director of Marketing, Director of Demand Generation. "Marketing" can be replaced by "Growth" depending on stage of company or org structure.

I've worked with early seed startups to Fortune 100 companies. I've done brand, growth, and product marketing at various times. The largest team I've managed had 25 marketers.

Things I do:

Write and execute marketing strategies, write and execute detailed marketing plans or GTM plans defining ownership, roles needed, scheduling Gantt charts, budget, and KPIs. Can do 50,000 ft strategy and roll up my sleeves and dive into Google Analytics.

If you are a founder and have never written ad copy or designed a landing page or can't tell the difference between demand gen and lead gen, but you think you know marketing, I'm not the person for you.
To be fair, Jack Dorsey rolled over his ownership into the new structure. There are few people who know twitter, it’s problems, and potential than him.
Riff – Instant office hours for whatever you want

Hey! Welcome to office hours, how can I help?

What is the most cost-efficient architecture for an Internet-scale search engine?

The most cost-efficient architecture for an Internet-scale search engine would likely be a distributed system, where each node in the system is responsible for a portion of the overall data set. This would allow for horizontal scaling, where more nodes can be added to the system as needed to handle increased traffic.

Which server brands do you recommend for the same?

For an Internet-scale search engine, I would recommend using a distributed system with server nodes from multiple brands. This would allow you to scale horizontally as needed to handle increased traffic. Custom hardware may offer higher performance per watt for the same functions that can be specified in software.

Is overclocking a server a good idea?

Overclocking a server can potentially increase its performance, but it also comes with risks. Overclocking can lead to stability issues and can shorten the lifespan of the server.
Sorry.

Im going to say this isn’t technologically useful.

REASONS:

1. Over 80% of breaches happen because of KNOWN but unfixed vulnerabilities.

2. Most attacks lead with phishing and account takeovers not software vulns.

Most people assume that if you scan all the things it fixes the problem or even empowers people to fix problems but it doesn’t.

If governments want to do something truly progressive then here’s a better option.

1. Use MFA preferably hardware tokens everywhere.

2. Catalog all externally exposed assets

3. Catalog all high-risk internal assets

4. Regularly white box pentest your assets (switch vendors annually) and implement a bug bounty program as well

5. Penalize any organization that doesn’t remediate their critical pentest and bug bounty findings
So what you are saying is, these people are playing the game Who can extract the most money from your workers? How awefull
What does that have to do with anything? The cost of bandwidth is just one part of infra costs, and it comes from peering agreements. Those are expensive because you're dealing with monopolies and they don't really have any reason to bargain with you.

People always say things like this, but i never see the interesting projects. Yes some are not as batshit insane as the ones that make the news for being crazy, but none of them seem "good" either.

It feels a bit like an unfalsifiable premise. You should do your own research until you find one that is good. If you haven't found a good one yet, you just haven't researched hard enough, so keep going.

People are treating Musk pronouncements like they did Trumps. Taking extremely literally even when it's obvious he's pulling your leg.
Totally agree with your last few sentences.

I don't think anyone is proposing making it illegal to boycott, it's just counter to a culture of free speech to try to punish people because you disagree with their opinions. That culture isn't legally protected, except the part where the government can't infringe on it.
Presumably he means per month not per year? As does the people above him paying $80 and $300? So his 20 year payment would be 2400 Euros.
What's the value of narrowing down the fediverse (or any social platform) into three subjective categories like that? To counter the validity of your particular ternary delineation, relatively speaking all communities are a "safe space": they all have their own idea of what is accepted and what isn't. Introducing such a "polarized" view to newcomers to the fediverse seems like a huge disservice and gives them a falsely antagonistic sense of what they're going to experience, IMO.

At the same time, I'm not sure what framing other people approach social interaction but not once do I think things like "left", "right", or "sides"... "divide". I'm nearing 40 years old and still don't understand rationally why people lean towards these simplistic labels when people in general don't nicely fit them at all. I'll see some toot I don't like and think "oh, don't wanna see that sh*", block the user or perhaps the whole instance (if it's one where most people posting there share such stuff I don't like to see). The specific political stance of the person or instance won't even cross my mind, because why do I care? I just didn't want to see some racist or hate-propagating BS, regardless of where it's coming from or what ideologies it could be associated with.

Anyway, just my $0.02 on this topic; I didn't want to see this kind of polarizing perspective go unchallenged.
Yea, I didn't have any issues with any of my buyers thankfully and was willing to write off any cases where people claimed they didn't receive the code because as you mentioned it's aa grey area. My only issues were with customer service but it has thankfully been resolved now.
I have the same question.
What is the software architecture to make that possible?
Does any open-source solution exist?
> What problem is k8s even trying to solve?

> Say you want to deploy two Python servers. One of them needs Python 3.4 and the other needs Python 3.5.

Honestly hilarious. The core value prop example is if you want to run two minor version different programming languages on one machine. In order to do that, you get to deploy and configure hundreds to thousands of lines of yaml, learn about at least 20 different abstraction jargon terms, and continue to spend all your time supporting this mess of infrastructure forever.

How many engineering teams adopt kubernetes because it's what everyone's doing, versus out of genuine well-specified need? I have no idea.

I use k8s at work, i know it has benefits, but it too often feels like using a bazooka to butter your toast. We don't deploy to millions of users around the globe, and we're all on one python version (for library compatibility, amongst other things). Docker is an annoying curse more than it's a boon. How much of this complexity is because python virtualenvs are confusing? How much would be solved if instead of "containers" we deployed static binaries (that were a couple hundred mb's larger apiece because they contained all their dependencies statically linked in... but who's counting). Idk. Autoscheduling can be nice, but can also be a footgun. To boot, k8s does not have sane defaults, everything's a potential footgun.

In 10 years we're going to have either paved over all of the complexity, and k8s will be as invisible to us then as linux (mostly) is today. Or, we'll have realized this is insanity, and have ditched k8s for some other thing that solves a similar niche.

edit: I realize this is a salty post. I don't mean to make anyone feel bad if they love to think about and use k8s. I appreciate and benefit from tutorial articles like this just as much as the next dev. It's just the nature of the beast at this point, I think.
