For what it's worth, longer range EVs also tend to support faster charging.

A 250 kW Supercharger only charges at the full 250 kW when the battery is under I think around 25%. After that, it falls off linearly as the battery fills. (EDIT: This is why it's better to do somewhat more frequent, but shorter charging stops. On my road trips, I typically charge to just 60-80% with the expectation of arriving at the next charger with 10-20%)

So if you have a 100 kWh battery compared to a 75 kWh battery, the 100 will give you more miles per hour of charging, simply because it can handle the full 250 kW charge speed longer.

We've been tracking JavaScript package manager performance and wanted to share real-world benchmarks that mighthelp others make informed decisions.

Actual measured results:

• pnpm: 50-60% faster installs than npm, 78% less disk space • Monorepo installs: npm (4m30s) vs Yarn (2m45s) vs pnpm (1m20s) • Memory usage: pnpm (80-120MB) vs npm (150-200MB) • With 50 projects: npm uses 15GB, pnpm uses 3.2GB

Real-world impact: - 20-30% reduction in CI/CD pipeline costs with pnpm - Fresh installs: 30-40 seconds (pnpm) vs 60-80 seconds (npm)

The disk space savings are the real game-changer. We have developers with 50+ projects locally, and pnpm saves ~12GB per developer.

Caveats: - Some older tools have issues with pnpm's symlink approach - npm has better compatibility with legacy projects - Yarn with PnP can be even faster but has more compatibility issues

Has anyone successfully migrated large monorepos to pnpm? We're seeing great results but curious about edge cases others have hit.

TBF I always read prompt engineering as the 2nd definition, not the first.

> 1. the branch of science and technology concerned with the design, building, and use of engines, machines, and structures.

2. the action of working artfully to bring something about.

So you're trying to learn what / how to prompt, in order to "bring something about" (the results you're after).

When it was founded in 2014 it was criticized as yet another glass building in London (technically a floor in this case) in a very prestigious location. And indeed as you could a lot of the funding went into the building, maintenance, events/catering and you could see random freeloaders loosely associated with the Institute using the space as a free coworking space. I think since the beginning, the PhD funding was great idea as you could do your research towards current issues, somewhat outside of the usual rusty academic echo chambers. But the fact that you were supposed to commute to the central London location, a lot of the grant went on train tickets or accommodation. As an early LLM adopter / practitioner, I went there for some sessions on AI Ethics and such and did not see that it was worth the millions pumped into the institution as we saw that whatever Captain Obvious insights (guardrails, data protection etc) came out of the Institute were completely ignored by the US giants. The current political twist toward practical applications in defence might actually be good for the institute as they will actually be able to practice some applied science but frankly I don't have much hope that my tax payer money is being put to good use here - it's always been a desperate scream for relevance and there's more and more of this action free nonsense coming from the government, like the recent OpenAI memorandum https://www.gov.uk/government/publications/memorandum-of-und...

This page has an illustration from that strange interlude during which photographs weren't mass-reproducible, so the image had to be manually engraved on a wooden printing plate to be reproduced.

"Our image above isn’t a photograph but a print made from an engraving, made from a daguerreotype – one of the first photographic processes. Engravings could easily be printed multiple times and used to illustrate books, whereas photographs could not. "

Coding is not mathematics, mathematics is a deterministic axiomatic system for describing quanta. Coding is the creation of instructions for computational logic that then is persisted in non-absolute matter as state. “Engineering” did not create the internet, the desire to communicate in new ways, as humans have wished to do for millennia, led to the internet. I honestly don’t even know how physics created the web when it was literally created to share text documents

If this is in response to Nick Wellnhofers announcement from three months ago to stop embargoing/priorizing libxlst/libxml2 CVEs due to lack of manpower (which I suspect is a consequence of flooding projects with bogus LLM-generated findings from students wanting to butter their profile), wouldn‘t it be possible to ship an emscripten-compiled libxslt implementation instead of libxslt proper?

> I wish there was another choice of mobile + accessories that was both privacy respecting and actively using open standards for the betterment of all, not just their own profits.

That's the rub. If you look at Android handset financials, there's almost no money in making Android phones unless the company making them is Samsung, and only certain models sell. Where are all of these profits going to come from?

I wonder if you'd get farther with a USB SIM adapter under desktop Linux in that regard. I think you'd be hard pressed to end up where you want to in anything more portable than a laptop, since phones themselves are designed to be glorified containers for your mobile ad ID.

I deny that query ID protection was the impetus for the development of DNSSEC and that the earliest advocacy for it as an operational security tool, rather than a (government-funded) design improvement for the entire TCP/IP stack, was about query ID prediction. Like you, I was there at the time; if the NANOG archives go back that far, you'll see me on the threads babbling about this.

This notion of DNSSEC signatures being widespread comes up in every thread about the protocol. Here's a little thingy I threw together because I got tired of typing out the bash "dig" loop to regenerate it in threads:

https://dnssecmenot.fly.dev/

Note that the Tranco list is international, so captures popular zones in places that have automatic (and security-theatric) DNSSEC signatures, as well as amplifying the impact of vendors like Cloudflare who have several different zones in the top 1000. Even with all that included: single digits.

It's been over 30 years of tooling work on DNSSEC --- in recent time intervals, DNSSEC adoption in North America has gone down. Stick a fork in it.

They have become popular in the last few years. They are smaller, lighter and thus more portable than traditional mounts. They also don’t need to be balanced with a counter-weight (although they usually allow for a counter weight to increase payload capacity, they don’t need to be perfectly balanced). This all saves in set-up time.

One disadvantage compared to traditional mounts is that they absolutely need guidance, and with a pretty fast guide loop at that (like 0.5s). You can’t do long unguided exposures with a strain wave. But anyone who’s serious about astrophotography is guiding anyway so that’s not really a big deal.

> It is a balance (compatibility vs attach surfaces).

What I'm trying to say is that it's a false dichotomy in most cases: implementations could almost eliminate the attack surface while maintaining the same functionality, and without devoting any more ongoing effort. Such as, for instance, JS polyfills, or WASM blobs, which could be subjected to the usual security boundaries no matter how bug-ridden and ill-maintained they are internally.

But removing the functionality is often seen as the more expedient option, and so that's what gets picked.

My english is pretty bad, its take time to write post in not sort of a 'pigeon English' :)

Regarding other commenters, about LLMs. Sure they're used, nowdays it's stupid to drop the oportunities that LLMS provide. But around 60% of codoe wroten by me, and CPU emulation is wroten by famous Mike Chambers in fake86 emulator. Sometimes, when code looks rought or stupid (why no struct, folks?) -- keep in mind it's target on very limited cpu power and MUCH more limited RAM of RP2040. Also, code mess of .inl.c cause we need maximize functions inlineing, each funciton call on pico took abonrmal amout of CPU cycles.

While RP2350 was some sort of gamechanger, resources is still limited.

"b-bu-but people can buy more slop and chinese gadgets, why aren't they happy?"

That's how you sound... they're unhappy because they can't afford a house or kids, because jobs are increasing precarious and unstable, &c. not because toilet paper and avocados are now 5% cheaper than in 1949

My (unskilled, uneducated) grandpa worked in the same place his whole life, afforded 4 kids and a flat on one income. I'm in the top 10% earners, so is my wife, I can't afford a flat that would be big enough for 2 kids.

In its current form, the game is a shell of its former self. They took away a lot of features and maps. They even combined the reviews of CS:GO and CS2 to make CS2 look better.

You can't even play CS:GO anymore. It was all moved to CS2, with cosmetics as the highest priority.

The hostage map rotation used to be 5 maps, with variety. They've cut it to 2 maps, and are outright neglecting any variety. You can play some other maps but only in private matches.

They even got rid of the very fun drop-in mode where you could do Last man standing in pairs.

It's like they don't even care. I've completely stopped playing since CS2 and I hope they can see the metrics of other long-time gamers who also stopped.

Moz also has no love for RSS, having removed support for live bookmarks in Firefox 64 (2018) and no longer displaying the RSS icon anywhere in the UI when a website has any <link rel="alternate" type="application/rss+xml"> tags. If you want to subscribe to feeds you have to jump through a bunch of hoops instead of it being a single click.

Fortunately, Thunderbird still has support for feeds and doesn't seem to have been afflicted by the same malaise as the rest of the org chart. Who knows how long that will last.

This is not true. I frequently use these spooky "ingredients" in home cooking. I use sodium citrate to make cheese sauces that don't coagulate. I use MSG if I need a source of glutamic umami. I've used various gums as thickeners.

These aren't some toxic compounds that machines put in our food. You can just go to a food supply store and grab them. MSG is just available pretty much everywhere.

Not the GP, but I can answer. My current vehicle is 35 years old. Prior to that, I had a '00 Jeep Wrangler for 15 years. Before that was a selection of older vehicles: an '88 Toyota pickup (that I dearly miss...), a '97 Ford Ranger, a '99 Dodge Dakota, and a '98 Honda Accord.

I keep a small toolbox in my vehicle. It's mostly inexpensive hand tools, but I include a Milwaukee M18 Fuel impact and a set of sockets for it - super handy for changing tires.

In my 25 years of driving, I've broken down probably a dozen times total. Of those, only twice have I required a tow - and one of those was in my wife's Kia Sorento, which we bought new.

Easily 90% of the usage of the tools I carry ends up being on other people's vehicles. I can swap a wheel on the side of the road in <10m with a bottle jack and a battery-powered impact, with no real manual labor involved.

Other breakdowns I've had in the past were things like the serpentine belt breaking or a coolant hose coming loose. Those are five minute fixes if you have access to a parts store. When the belt snapped on my Jeep in the middle of the night on a trip a few years ago, I used an pair of my wife's leggings that she had packed to get us home. I just tied them by hand, bypassed all the non-essential stuff on the motor, and drove the ~50 miles back home to deal with it the next day.

80% of all USD in circulation was printed between 2020 and 2022, poor bond performance ==> "there is no alternative", unhealthy amounts of gambling, central banks executing unhealthy amounts of QE.

All of this causes money to run to the stock market, equity valuations to go crazy high, and also concentrate at the top. This is seen to be true today as the equal-weighted s&p lost to the cap-weighted s&p by the largest margin on record in 23-24, more than 10%. During relatively healthier times, it usually outperforms by 1%ish. Check the expanding gulf between returns of the S&P top 10 and S&P next 490.

Execs get paid in equity more than employees, and so their TC accelerates faster.

Gambling (whitewashed terms: speculation/trading) is always the original sin :) Has been since the bronze age. Most of what most participants in the stock market do today is just meaningless zero-value drivel. Due to the tragedy-of-the-commons effect, it is almost impossible to do disciplined, "charlie munger"-style investing in the market today.

Historically, these conditions have always mean-reverted. But it has never been pretty :)

As others have explained the Benaphore is a speed-up for an existing OS primitive, but the futex is a new primitive that's often much better suited to the problem you have. Benoit Schillings uses this name "Benaphore" but never claims explicitly to have invented it in the article naming it, either way though Benoit worked for Be Inc. which were making an entire OS including its kernel, so they could have provided the better primitive. But they didn't, BeOS provided the limited semaphore primitive you'd have seen in a typical 1980s or 1990s Unix.

Given that primitive, the Benaphore is a good way to use it, like if you've got a 1930s refrigerator and you've got a clever technique to reduce frost build-up - a modern fridge has a smarter controller and so it'll just defrost itself anyway automatically, no sweat. The Benaphore is thus redundant today - like that anti-frost technique for your 90 year old fridge.

Transport security decisively addresses query ID prediction attacks, without requiring forklift upgrades of the entire DNS infrastructure of the Internet, and has the benefit of working for individual sites even when not widely deployed elsewhere. If the concern is transactional attacks like this dnsmasq thing, advocating for DNSSEC instead of DoH/DoT seems like engineering malpractice.

Piling on with others; it's avoiding the context switching and copying between user and kernel that improves performance.

If you can stay in user space, or stay in kernel space, that is likely to be better performance than going back and forth.

This is why sendfile is great; rather than storage -> kernel memory -> user memory -> kernel memory -> network, you get storage -> kernel memory -> network. That's two less copies, and fewer context switches.

Not sure if this is a part of it, but there are places where "engineer" is a protected title that requires a degree or license. I work with a bunch of folks in Quebec and they have to use the title "software developer" unless they are a member of the Order of Engineers. I find this to be pretty silly considering someone can have a degree in Mechanical Engineering and use the title "Software Engineer" but someone with a degree in Computer Science can't.

Click on the timestamp of the post and then click the "flag" link. A few members in good standing flagging a bad comment will kill it. That's the most expedient way to prevent a troll post from spawning a big off-topic thread that detracts from the content of the submission.

It's also good practice to downvote a post like this before flagging it. They are separate actions, and once an account's cumulative karma drops to -12 (IIRC), all of its posts become dead-by-default.

I'm glad I didn't, though, because I had no idea how the LLM is actually interpreting my commands, and have been frustrated as a result.

As I understand it this is precisely why in Haskell and OCaml standard libraries we get lots of things like

map : (a -> b) -> a list -> b list

instead of

map : a list -> (a -> b) -> b list

The main argument (data to be operated on) is positioned last, after the others which are more like parameters that tune the function. It's to allow chaining these things up left to right like Unix pipes:

map f l |> filter g |> ...

> I'd presume that most of those people are using it in some capacity, it's just that their numbers are seen as too minor to influence the decision.

I think the idea of that is reasonable. If I used XSLT on my tiny, low-traffic blog, I think it's reasonable for browser devs to tell me to update my code. Even if 100 people like me said the same thing, that's still a vanishingly small portion of the web, a rounding error, protesting it.

I'd expect the protests to be disproportionate in number and loudness because the billion webmasters who couldn't care less aren't weighing in on it.

Now, I'm not saying this with a strong opinion on this specific proposal. It doesn't affect me either way. It's more about the general principle that a loud number of small webmasters opposing the move doesn't mean it's not a good idea. Like, people loudly argued about removing <marquee> back in the day, but that happened to be a great idea.

> But if infinitely more popular techs (like Flash or FTP or non HTTPS sites) can be deprecated without much fuss... I don't think XSLT has much of a leg to stand on...

Flash was not part of the web platform. It was a plugin, a plugin that was, over time, abandoned by its maker.

FTP was not part of the web platform. It was a separate protocol that some browsers just happened to include a handler for. If you have an FTP client, you can still open FTP links just fine.

Non-HTTPS sites are being discouraged, but still work fine, and can reasonably be expected to continue to work indefinitely, though they are likely to be discouraged a bit harder over time.

XSLT is part of the web platform. And removing it breaks various things.

They can't afford kids because of a totally different reason. The poorest countries have the highest fertility rates. The richest ones the lowest.

Yes housing is proportionally higher but home ownership is pretty much constant https://fred.stlouisfed.org/series/RHORUSQ156N

Crucially the cost of everything else has come down dramatically to balance for rise in home prices.

> I'm in the top 10% earners, so is my wife, I can't afford a flat that would be big enough for 2 kids.

This is true but this is not because CEO wages are rising but despite it. IMO this is happening because people moved to the cities and enough houses were not built in time (you try to answer the question as to why). Your grandfather probably lived in a rural part of the country and could afford a big house where there was no demand - something you can still do now.

There is another reason housing prices have also gone up which is not talked about often - while prices of other things reduced people had more to spend on other things. They chose to put remaining on housing because.. well where else would you put it?
