I don't think so. A/B testing is just not a cure-all and alternative for good design, that is all. I mean, if the pattern is 'don't bother thinking too much about ux, just A/B test everything in PROD to death', then yeah, you are right.

However, there are many products which allow users to enter into a beta or test group, where they are the willing subjects to their experiments (in exchange for the latest shiny new stuff). This has the aspect of consent, leaving the 'stable ring' free of such variability. The fact that google and many startups are not using such consent and offering stability, doesn't mean it can't be done or isn't done.

How is that any harder than Afghanistan => Afghan.
Nope that's just bullshit.

If you would price in co2 creation for no real value you would see that for society (most of us like 99,99999%) it's a net negative.

It also derails investment which would make more sense as the Bitcoin market is decoupled from the normal market.

The local smelter or papermill or any other energy intense industry has to play by totally other rules that Bitcoin.

The fact that they claim that they should down their miners is also not even proven and should make it very unrealistic.

Miners loose tremendous amount of money while not running. They can't afford to just not run for a long period.

And I have seen mining rigs in Texas who uses ac to cool down their shit.

They consume even more.

We start to be smart and accept that energy needs to be used for things helping people not gamblers.
Maybe for certain segments/formats, but TikTok doesn't do long-form videos, does it?

Most of my YouTube watching is things like Anton Petrov's 15+ minute science videos, PBS Space Time, hour+ live streams, DefCon/Blackhat/Other Conference talks, and a hundred other things that I don't think are available or desired on TikToks platform (and maybe not even supported? I'm not sure what the max video length is on TikTok).

> New York is one of the best, but still shitty by EU standards.

If we're talking about concrete things like throughput, the MTA is one of only a few systems with round-the-clock operation, and I don't think anywhere else matches its scale and reach.

The filth of the stations are a legitimate complaint...but given that my primary interest is my transit system moving me from place to place, I'd take it over the majority of EU systems in a heartbeat.
Build it in the car and offer a purchase option in the center console. Heck do A/B Testing where you offer a lifetime purchase (Upfront or monthly) and a monthly subscription. Then see which sells better.
Except.... This isn't true.

I can't just "turn on" adaptive headlights because the vehicle doesn't have the necessary camera to scan the road for oncoming cars installed.

I can't just "turn on" adaptive cruise control, because my vehicle doesn't have the necessary front radar installed.

I can't just "turn on" the HUD, because my vehicle doesn't have the necessary dash components physically installed.

The number of different hardware permutations of most modern cars is eye-watering. For most options, if you didn't get it installed from the factory, you're looking at an expense retrofit.
There is ~100GW of solar generation in ERCOT's interconnect queue.

What cesarb said already, rings true to me: even if these devices were available at a price comparable to retail, no way in hell I would buy a special "Linux phone/laptop" in addition to my regular one. I just wouldn't have had the financial resources to explore the world of "open" things.

To address your proper comment, any amount of time spent on window-shopping any "open hardware by design" project pricing pages will show exorbitant amounts vs comparable spec consumer/mainstream hardware.

Examples:

* Talos Workstation, any Librem product, MNT Reform: self-explanatory. Absolutely mad price range for someone who is not sure whether they should buy one/need one, even for someone already in full-time employment in the IT field. If that's what you need or want, and you're sure you both need it and can afford it? Great. But not accessible to hobbyists.

* the Framework laptop/System76: the most basic configurations are around $1k/£1k. I don't think it's likely I would be able to obtain a cheaper one second-hand locally.

I am not going to make a survey of all Linux/open laptop vendors out there who sell worldwide (or at least, US and Europe), but I assume it's similar. If you can point to reasonably priced laptops from 2 different vendors or more, with specs suitable to using the laptop as a modern-day daily driver, I will retract this point.

* OpenPandora/DragonBox Pyra: I was extremely interested in this one, but bloody hell, spending 300-500EUR on a piece of hardware that will basically only ever play source ports of games and emulators? I knew straight away that I would only ever lick this thing through the virtual shopfront window, because for what you got, that price range was extremely hard to justify. This was before ARM gaming was a thing in any way.

* OpenMoko: as far as I know, the only attempt at an open hardware smartphone (that got something off the ground) until the PinePhone came along. Reading about it at the time, I recognised that its hardware is outdated, and that the software is irredeemable to anyone not willing to put blood, sweat and tears into it. Meanwhile, I could've picked up a CyanogenMod Android phone and had 80-90% of the benefit, for about the same price, and comparable or much better specs.

I don't blame anyone on the list above for the prices, and I don't think their products are crap. All I'm saying is that for someone on a budget, getting one of those is unviable. Either it's too expensive outright, or when it isn't, the result is not usable as a daily driver because you would give up basic features that you actually need. And when I mean basic, I mean "it cannot use school/work/bank/government/messaging apps made for the current duopoly in this device category", not "uses an older version of USB".
How does any of those things make it "essentially impossible for any US-owned or US-hosted site to comply with GDPR"? Is it legally required in the US, for example, to use Google Analytics?

It's like saying Subway spent a billion dollars to promote how one guy bought $10K worth of sandwiches over 10 years. Like, yeah, that's a technically accurate description of the Jared from Subway campaign but the actual example is meant to stand in for a larger message.

Same with Dominoes, they obviously spent more than $100K in charity over the entire year, they are using 1 $100K campaign as a standin for all the other charitable stuff they did because it's a much more compelling ad than just a spreadsheet scrolling for 30 seconds.

Do you concede that inflation robs people of purchasing power? That's the most important point from that.

I can understand that the "for their own enrichment" part of that sentence is a bit debatable. It's true (as far as I know) that the central bankers are not personally building giant Scrooge McDuck money bins and siphoning cash directly from their monetary policy decisions in there for swimming purposes.

However, you can point out that the money and power they gain is due to their willingness to keep business as usual (inflation) churning. And let's not forget that the central bankers can manage to get high 6 figures speaking engagement fees, at least after they're out. I can't be sure what level of quid pro quo goes on with all of that, but they certainly do manage to enrich themselves by playing their part and continuing the generally policy of inflation.

Making a Heated Seat
Can't we use our USA-centrism (centricity?) to make the behavior of the country drop-down just a little bit better? Surely I'm not the only one burdened with having to scroll past a hundred of these .. ahem.. OTHER... countries.. to find "United States of America".

Yes, I could begin typing "Unite.." but we all know that ends up on United Arab Emirates, and then when I continue on to "...d Sta..." and it doesn't work, only to find out this country picker uses "USA" or something similar so it breaks the autocomplete muscle memory.

Clearly, if we're the center of the known universe, we could use our power to make it a little easier to enter my billing and shipping information.
While this book is getting a little long in the tooth (the title needs to be inflation-adjusted now, I suppose), it's still a fascinating read. The authors considered "self-made" to mean that the subject did not receive monetary support from their ancestors as an adult in the form of trusts, inheritance, or other forms of "economic outpatient care" (their term).
I'm only familiar with the U.S., but I wouldn't be surprised if this was a problem in other western countries.
My understanding is that it is also 12-13 hours of exposure for the Webb image vs weeks for Hubble.

A process to respond to these notifications and mark obvious bs ones as bs and prevent them from being used as a strike on a person's record. A process to ensure validity of these notifications. A process to ensure AFTER deciding to fire someone management didn't go on a fishing expedition for JUSTIFICATION for the firing. Enforcement of consistency in firing, making sure they aren't just shotgun recording every possible thing so that they can use that later to go fishing for justification for firing someone. The manager used X to justify firing Peter? Enforced consistency in firing based on these notifications.
Sure, but that's not really A/B testing, those are more often called staged rollouts or progressive rollouts.
I've seen and used the phrase "NeXT bought Apple with Apple's money" for that acquisition, they didn't just replace Gil Amelio with Steve Jobs, they also had a huge fraction of their management and tech leads swapped out with NeXT folk in pretty short order. They also turned over a huge number of board members in '96-97 as Apple flailed then reformed. Apple spent $429M on NeXT (Apples market cap at the time was around $2B) when they were losing about $700M a quarter and expected to be bankrupt by the end of 1996. They slid through the bad spot partly on a $150M investment (...possibly motivated by antitrust avoidance) from Microsoft.

Steve drove (Chief Operating Officer) Marco Landi and (chief technologist) Ellen Hancock out even before he became CEO. Bertrand Serlet (1997-2009) then Craig Federighi (2009-) ran the (variously named) OS team and Avie Tenivan was the tech lead, all former NeXT folks (which makes sense because Apple failed at 3 OS projects then shipped reskinned NeXTStep). Bud Tribble followed Steve to NeXT then back to Apple in various VP roles. George Crow and Jon Rubinstein did the same kind of loop working on hardware platforms at Apple-NeXT-Apple. Mitch Mandich became SVP of sales almost immediately after the acquisition. Etc.
They wouldn’t, actually. It’s been tried and they just don’t have the network effects to be comparable to Uber. A lot of big city rideshare is visitors, tourists, business meetings, etc. who already know Uber/Lyft UI and aren’t willing to download a new phone app for each city they visit, regardless of if it’s better for the drivers.
I rarely passed others and my car at the time couldn’t go above 80 so I was acutely aware when the traffic was faster than I am.

I think it’s most likely changes in I-88 since I lived there are responsible for any difference.
Economy is not the only indicator of value and to treat it as such is an overly reductive view of the world.

If a market enables breaking of laws created by democratic processes, any economic value is outweighed by its negative societal and democratic value.

Thanks. I really like the first approach.

Now that I work as half data engineer and half infra (cloud). I do have a few hobby projects using C/C++ (e.g. embedded for C and game programming for C++), but nothing really completed and polished. How do I convince someone to give me a job to work on low level systems, even as a junior?

Should I continue working on low level projects and hopefully they are good enough, or there are other approaches?

TBH I'm willing to do free part-time work on sys programming if given the chance, but industry doesn't work like this.
Yup. Some apparent misses are because the images are zoomed, so they can be shifted and reused with different coordinates. Unfortunately some images end up with the pointing finger out of frame.
Sadly the only rational choice left might be Sony. I chose between Sony and M4/3 five years ago, went with M4/3, and now regret it took should've gone with alpha APS-C.
> It's a minuscule problem right now because of SB. Why spend time and effort if it's likely you'll encounter a protected system.

It was a minuscule problem even before SB and even today still is without SB. For most people who are exploited up to the point were malware _can write directly to the boot hard disk_, "boot chain safety" is at that point the least of the user's problems. Their data is already uploaded to a Russian server, ransomware installed, their webcam turns on without the warning LED, and all their OS security including the root account has been compromised up to the point that the attacker can start erasing off-site backups without the owner even noticing (no need and no point to compromise the boot chain).

The only scenarios were boot chain integrity would apply are evil maid scenarios where the attacker can write to the boot disk externally, i.e. _not from the user's OS itself_, and these are way outside the worries of the immense majority of users. Correctly, IMHO.

> Not really massive, mostly like absolute bare minimum [effort], if you've read them. But okay.

> most Linux distros barely support existing Secure Boot which requires much less effort than running your own CA does.

This is a just cheap criticism (even insulting) without even providing any reasoning whatsoever. And I say that as someone who has criticized Linux distributions from trying to play under the arbitrary MS rules.

Most if not all Linux distros do their own CA already. They sign packages, after all.

Ignoring the political implications of the question for a second, if nothing else when people ask to be referred to by a different name, their chosen name is usually at least reproducible on the keyboards in common use.

Well, the Olympus FT system had its last camera 2010. But there was the migration path to mFT, which supports FT lenses. You might though hurry to grab the lens adapters, as they are no longer in production. The mFT system is quite alive and the camera spin-off from Olympus, OMDS, seems to do well with the recent OM-1 camera. You should definitely give it a try.
Compromising an OEM remote starter is not really a big problem anyway. The vehicle still will not allow you to shift out of park, and any modern system will only start the vehicle a limited number of times for a limited duration. They're inherently designed for unattended operation.

Yes, it is cheaper due to economies of scale to include the hardware in all models, and the fact that they're selling it at all without enabling the feature means there's already a profit margin there.

I like your focus on better questions. "those topics and any other that come up" was especially vague as was "semi-unknown". ;-)

FWIW, I doubt anyone was suggesting "large scale applications programming in C"..Just the nuts & bolts & basic vocabulary..the way a program/process interacts with an OS, etc. in the very simple cases/scenarios. The main (but not only) way people use Nim is through the C backend. { The code generated by the Nim compiler is not that easy to read or intended to be so, of course. } There are also OS books to consider like The Design of The Unix OS or Advanced Programming in the Unix Environment. These also use very minimal little C examples. Everyone learns differently, though. I think more delineated goals and background level would yield better advice for @budafish.

Teaching has also evolved over the decades. Teaching of C was/is more "hand in hand" with the ideas the poster was asking about. For example, the K&R C book walks you through writing both stack allocators and heap allocators on top of raw memory.
> how hard would it be to reduce the time delay between identifying a point and displaying an image

Easy, I expect. I assumed there were two reasons for the delay:

* Simply a transfer delay, though even for images not seen before I'm only seeing between 20ms and 80ms in total for that each time (though it does seem to request each twice).

* Debouncing, to avoid requesting many images needlessly while a user moves the mouse around the page.

* For show, to make it look like it is doing something more clever that requires noticeable processing time!

All but the transfer delay can be removed easily as I think they are put in deliberately, and the transfer+render delay is short enough not matter for what you describe wanting to try.
Yes, it's a combination of both the primary mirror and struts. The JWST website has a very helpful infographic explaining: https://webbtelescope.org/contents/media/images/01G529MX46J7...
Nikon is still producing a few manual focus (Ai-s) lenses. Or if not actively producing any more, then they're at least not officially discontinued so far. Since the 55mm and 105mm Micro-Nikkors pop up in machine vision applications, I'm assuming they have long-term supply agreements with industrial customers for those lenses. (A lot of industrial cameras are Nikon F-mount)
