Silicon is made by reduction of silicon dioxide with carbon in an arc furnace. One heat that furnace with concentrated light instead, I guess, but it requires very high temperature. There is also a process using aluminum as the reducing agent.

Very pure silicon for PV is produced by converting silicon to SiHCl3 by reaction with HCl, followed by distillation and thermal conversion back to silicon. Recycled silicon could be treated the same way for purification; it's going to be less contaminated than the raw silicon coming from silica reduction.

I think you'd probably go a thin film route to make PV yourself; much less semiconductor would be needed. Maybe copper oxide?
myworkday is the flagship reason why!

Find a job postsing on linkedin, click apply and you are redirected to [abc].myworkday.com.

Need an account first, so you create your 20th one on *.myworkday.com

Upload your resume for the 20th time, need to fix the exact same data mistakes myworkday makes every time you upload your resume. Repeat.

What value does myworkday offer? why cant i just create one account on myworkday and use it for any job i apply for?

Why is myworkday so prevalent when the experience is terrible from a job applicants perspective?
It seems like she invested herself and her ego too much into the job, almost caring more about the "position" than the money, which is very weird. I would just take the paycheck and the easy work.

The XPS 13 I bought a few years ago ended up being a decent development machine, with a price point hard to match for the form factor and specs. And the Dell crapware on it was relatively low.

What are good alternatives for non-Apple slim 13' laptops with good screen real estate, low weight, loads of RAM and a decent price range?
This looks like it belongs on a set of a budget sci-fi movie. So bland, neither elegance nor character.
>Employers don't know ahead of time which employees will leave and which will stay

I may be a bad example, but I can assure you every employer I have ever left new I was unhappy in my role before I left.

I always have frank and open conversations with my managers about my expectations for growth, wages, etc. These are not Ultimatums, but more "In 5 years I would like to be" type conversations.

Now as a manager I have gotten similar feedback from people that work from me, sometimes you have to listen closely to understand what they are saying in reality as many are not as direct as I am, but the feedback is there

I think managers just simply ignore it in most cases
> Based on my conversations with Meta employees, the new policy shouldn’t have a material impact on the company’s revenue. But there is concern about the precedent set and that Apple will eventually require the same rule for Meta’s standalone ads manager app. Thanks to Apple’s current logic, that app is currently exempt from having to use in-app purchases for boosts because the ads that are bought aren’t displayed in the app itself.

Article title got my hopes up, but this looks more like an indirect shot, or maybe setting up to do some damage later. Fingers crossed! We can do anti-trust at Apple after they've successfully done the world a favor and killed off Facebook.
> It’s not like Facebook is a competitor of theirs

If Facebook is not a competitor then there's no issue is there? The regulator would step in if there were unfair competition. If they're not competing then there can't be any unfair competition.
"I wonder how much embedded energy is there in that giant fresnel lens. These things are notoriously expensive."

It is basically a transparent sheet of plastic with some of the plastic carved out. So likely not much energy.

They are only expensive to buy in large, because there is not really a market yet, except hobbyists.
Asking why there is anything is also metaphysical. Metaphysics is where the interesting unanswerable questions are :)
Yes, websites are still the one place where users have some degree of parity with the vendors. They are, however, being actively phased out. It's a long process, but it's clear. New banks and quasi-banks often don't even have a web portal. Old-school banks have been actively pushing apps as the primary interface. In recent years, they've been pushing apps as preferred auth mechanism for confirming logins and transactions initiated off-app. How long before it'll become the only mechanism?
Yeah, we also find this interesting. Arguably, though, GP is far worse in all metrics. Thus, it is not really our closest competition.
People who are successful in a system count on its continuation (and often won't invest in a few hundred $/€ worth of emergency food, water, heat and light), people who are not successful in a system count it's failure (and do real, or ceremonial 'prepping', telling themselves and others that they will be relatively more successful when the inevitable disaster strikes).
I worry that there are probably 1000, but they are all forced to clamor for attention so hard to get noticed, that they'll be all hype over substance. I think the internet's "everyone has a voice" brings its own problems. It's like a Denial of Service attack on our attention.
You're correct, others like TikTok and Twitter and dating apps correctly consider a user asking to show their post or profile to more people a digital service, and use IAP per the contract with Apple. FB/Insta were claiming it's an ad so they could disregard. Since FB wouldn't resolve, Apple closed the loophole.
My last fews doctors visits at my German GP doctor have taken me 25 calls or more to get to a person. This is a practice of two doctors, not a huge house. I think Covid has done a number to those telephone systems, especially since you can only get vaccinated and PCR-tested through gp's now for the most part.

I'd love to know if they are aware how bad it really is. You're sick and want to just stay in bed, but need to see them to check up on you. And then you lie there and call them 25 times on repeat until finally, maybe, someone picks up.
You can't patent "pure math" but given that describes literally anything that it is possible to do on a computer, including simulating a physical device, we know that there is an intrinsic point where things go from "math" to something patentable.

The rationale for "you can't patent maths" is basically "you can't patent a fact".

Blanket anti-software patent people take a maximalist position: if it's a step of instructions it is maths, so should not be patentable. I think that is absolute nonsense, and it is an explicit statement that if you ever come up with anything idea, no matter how much it cost you to invent it, or develop it, it has zero value - because apparently the hard part of complex and new technology is writing code, not developing the technology in the first place. It also means you get some absurd results: the same invention would be patentable if you made a mechanical implementation, a purely electronic one, probably an ASIC, but probably not if it was an ASIC executing instructions from a builtin ROM. Because suddenly it becomes "math".

As I said originally, the problem is not patenting "software", it's that the idiocy of the US patent office means that you can make a patent document that has no information that can be used to implement the patent, and thus the patents are inherently open to abuse.

The core problem with software (and worse, process) patents is that they let you patent an idea, rather than an actual implementation of an idea, which is what physical object patents are required to do. The whole reason patents are public is so that the public can look at a patent, and use that document to implement the idea being patented, but if all you've done is patent the idea then all the public can do is see that you had an idea but didn't know how to actually build it (which is what patents are _meant_ to be for).
My gf bought a dell xps 15" with OLED and an i9 processor. I think it was reasonably priced compared to competitors but it just so happened that her screen broke, or it got loose.

She called Dell and they sent a new one so she could transfer her work over to the new machine and picked up the other one a few days after. All and all it was a good customer experience.

In my view, it seems like it has good build quality (in general, stuff can happen) and good customer support. Although she will never run linux on it. This website reads like a frustrated developer who decided to take matters into his own hands. I am very doubtful that this is the common experience, at least if you order directly from them. Sure it may have driver issues but at least they have an option to ship it with linux and without paying the windows tax, most companies don't even do that.

I personally use a Thinkpad t460p from 2013 that runs Ubuntu and still works great honestly, even the battery life. I will soon upgrade to a desktop instead of a laptop so that I can run more heavy duty stuff like training models.
If you expand a NN to decision trees, the resulting decision tree(s) can take up orders of magnitude more space and take orders of magnitude more time to run than the original NN.

> A paywall is great if your goal is to use it as a stick against non-paying folks

It wouldn't count as a stick since it's not punishment for some behaviour. There's obviously an ongoing cost to running a website, and not just a one-time cost at the beginning, so I think it would be widely accepted for an annual contribution to be mandatory.

(Excluding deranged folks demanding free services, or those who can't comprehend that ongoing costs exist. Which should only be a tiny segment of the community)
At the interview stage, one doesn't need to decide if they're evil or stupid. Just say 'no' and move on.
It's pretty common to use a u instead of mu in situations that need just plain ascii. I don't think anyone's confused. uTorrent comes to mind, too.
The person in the article did not reserve a room at a major chain hotel, so they would not get the benefits of having the hotel brand’s policies enforced.

That is the benefit of reserving Hyatt/Hilton/Marriott/IHG/etc. They have contracts with the hotel owner (franchisee) that will allow them to get their money that they recompense you and heavy penalties to the franchisor for the franchisee not following policy, incentivizing the hotel to not screw the customer in the first place.

Hotel owners change brands all the time too, and the existing hotel brand notifies and migrates reservations to other area hotels when that happens. As opposed to this situation at some random unaffiliated hotel in NYC.
We did try it a bit a while back, but did not have conclusive results. I expect you can bend it to perform better for larger datasets, too, but how exactly I cannot say for sure. The bootstrapping is definitely a good candidate for this.

Not just Doctors, but dentists and that whole group have major issues with their "customers".

My dentist requires i cancel an appointment by calling in with 2 working days notice. Failure to do so can result in a charge.

She has also called to reschedule my appointments with under one day notice???

Last time she did this, i told her there will be a short-notice cancellation fee. She refused to pay, and refused to recognize the irony in what she was doing.

She also texts you to confirm your appointments, but the only option you get is to "accept" - you cant respond to cancel/reschedule.. this must be done via the phone only???
Me too! Whenever Judith Hann came on (she did the health stories, if I recall) I would roll my eyes. You're immortal when you're young, after all! :-)
Right — the bank is trying to control how I use their service “for my own safety”.

That’s not a theoretic DRM issue, but a practical attack on the software ecosystem.
I'm super pumped about the speed boost.

The new exceptions are a clear improvement.

I totally don't get 'Variadic generics' that's not a word I'm familiar with.

Why they won't win. not enough people vote for intelligent people for office. They would rather vote for people they want to have a beer with.
Yes, but when you live off-grid most of the systems you use don’t use power (if you can avoid it). You can also build a faraday cage and store replacement electronics in it.

My neighbor does both. I actually also store my emergency solar power source and radios in a faraday cage for this reason. It’s like $100 to build one that can likely survive one of these major events.

> The XPS 13 I bought a few years ago ended up being a decent development machine, with a price point hard to match for the form factor and specs.

Good experience for me as well, although the point about not great Linux compatibility is correct (it seems that some hw fixes were not upstreamed in the kernel).

> What are good alternatives for non-Apple slim 13' laptops with good screen real estate, low weight, loads of RAM and a decent price range?

Thinkpad X/Z/T likely fits the bill (of course, within the limits of YMMV). They optionally ship with 32 GB RAM, and Ryzen 6000 series.
>Can I pay $5 to LinkedIn

why should you have to pay? They're the ones that want it.
> old Thinkpad

Except older hardware is terrible from a price/performance/power point of view. The minute you actually start to use the computer for something intensive, you'd rather have a more modern, faster, lower power-consumption laptop.

It shouldn't be too hard to find 8+ hours of battery life from a typical $700 laptop these days. Add a few more hundreds of dollars to get 12th or 13th gen Intel and/or M1 Macbooks and you'll get to all-day designs.
It works quite well, a lot of "anti-malware" is invasive malware by design.
I'm surprised the electrical demands of Greater London can be supplied with so few transmission lines. For comparison the city proper of Toronto has slightly less with a fraction of the population.

Surely a significant portion has to be underground?
Eh, I think you picked the wrong side of that comparison. JavaScript looks like C by virtue of age and influence.

It's common to remark on a language being "C-like"; not so much that a language is "JavaScript-like".
My mom used to joke that in our family, we don’t end up in homes because we all die of cancer before retirement.

Well, joke’s on her, she’s still alive at 70 and I survived my first bout with cancer at 36 already so she was wrong on two counts. Still didn’t put any elderly family in any home though…
>loads of RAM

Same! I'd love a laptop with a P or even U series processor that can handle 64 GB of ram.

The H series processors that you typically need to step up to generate more heat than small computers can dissipate and are thus frequently throttled.
Thinkpad carbon x1? new ones are 14" with 16:10 aspect ratio. Very slim and lightweight compared to macbooks (new 14" macs are rather heavy). They are a bit on the pricey side.
Beyond 2000 was a wonderful show. Funnily enough the one episode I remember the most is the one about RFID tags and possibly using them for scanning purchases in shops, where you'd just put your bags in correct place and it would count them up - with a joke that it won't work for everything, pointing to loosely packed vegetables :-)

What you’re not getting is the conscious part of “conscious decision”. The brain makes the decision BEFORE the consciousness is aware of it. But that’s not how we think we decide stuff; the experience we have is that we consciously choose to do something. The experiment shows that decision is actually made by the unconscious part of the mind, and the consciousness is only made aware of it later, while still believing it was in control the entire time.

Friedman: tell me is there some society you know that doesn't run on greed? You think Russia doesn't run on greed? You think China doesn't run on greed? What is greed? Of course none of us are greedy, it's only the other fellow who's greedy. This the world runs on individuals pursuing their separate interests. The great achievements of civilization have not come from government bureaus. Einstein didn't construct his theory under order from a from a bureaucrat. Henry Ford didn't revolutionize the automobile industry in that way. In the only cases in which the masses have escaped from the kind of grinding poverty you're talking about, the only cases in recorded history is where they have had capitalism and largely free trade. If you want to know where the masses are worst off it's exactly in the kinds of societies that depart from that. So that the record of history is absolutely crystal clear that there is no alternative way, so far discovered, of improving the lot of the ordinary people that can hold a candle to the productive activities that are unleashed by free enterprise.

Donahue: so it seems to reward not virtue as much as ability to manipulate the system.

Friedman: and what does reward virtue? You think the Communist commissar rewards virtue? you think a Hitler rewards virtue? You think, excuse me, if you'll pardon me, do you think of American presidents reward virtue? Do they choose their appointees on the basis of the virtue of the people appointed on the basis of their political clout? Is it really true that political self-interest is nobler somehow than economic self-interest? You know, I think you're taking a lot of things for granted. Just tell me where in the world you find these angels who are going to organize society for us well now I don't even trust you to do that let alone myself

Founder of AppMap here. We are a seed stage company so we’re building out as resources allow! Would love to get to Eclipse at some point.

You can also do all the AppMap things using the command line - make AppMaps, open them in your browser, run analysis. But because it’s less tightly integrated with the code, some people find it less satisfying.

If you want try out a purely CLI experience, install @appland/appmap from NPM and run the help command. You’ll see a full suite of commands.
I have been using the same Dell XPS 13 for about 6 years now, and I cannot say agree with most of that article. The Dell XPS line was my goto recommendation for people when they ask what laptop they should get.

Dell XPS support is also fantastic, if you go though the business channel and pay for support.

That said, Dell XPS is no longer my recommendation as the "New" line is a serious downgrade. They removed the headphone jack and added a touch bar. The amount of disappointment I have is immense. They took their best line and decided to make it horrible.
holy crap, that was exciting. so much to say, but would only spoil it for others.

> That never worked and will not work now. You can't choose something that's not being offered.

Why do you think you're entitled to something that's not being offered?

I think there's a general point here about how retail banking is not really an ideal free market, because the barrier to entry is too high. If no bank is providing a set of services that fit the compromises you want to make, then either your problem is with the government (who arguably over-regulate the space) or not enough people share your values to warrant creating a banking business around it.

> Well, sort of; a service agreement is a relationship, and TPM/remote attestation is a huge overreach by the corporate party. It's only fair to want to push back on what's becoming an abusive relationship.

On the flip side, the bank has to manage a complicated series of risks, and their investors might not want to pay the mitigation costs of the risks created by allowing anyone to use their service however they like. Hence the ToS.
I worked in one of Dell's outsourcing partners' call centres (admittedly I left almost 15 years ago), and back then it was the same people manning both consumer and business support lines. Towards the end of 2007 Dell started separating the two segments and that's where the problems started (edit: not sure about the exact date -- processes like that tend to take a while to plan) :

* Dell European consumer division was centralized and controlled from Ireland (IIRC).

* Consumer models like Inspiron and Dimension had a noticable drop in build quality.

* Support agents were forced to adhere to strict scripts during support calls, rather than use their own brains.

* Support agents had to convince a certain percentage of customers to replace parts themselves, rather than getting the on-site service they paid for. Agents not fillin their daily quotas were disciplined.

* Exceptions to the scripts had to be escalated. In many cases, Dell would outright ignore local consumer laws when handling complaints.

I'm sure things might have changed since then. Personally, I'm not taking the chance and will never buy a Dell product again, if I'm given a choice.
It's sort of obvious that these concepts of consciousness and memory are related. To be conscious (aware) of something, there must be a memory of it, right? Otherwise, does it really matter.

It makes me think about the drugs that disrupt memory, like midazolam. If you're undergoing a procedure with "conscious sedation," you may be, for fleeting periods, aware of certain things, but these drugs effectively reduce that memory duration to near-zero. And in that case, there's hardly a different between not feeling pain because you're unconscious and feeling pain for an infinitesimal period because you're unable to remember the prior period's experience.
And soon "potentially vulnerable hardware" will be anything except AT&T devices, and we'll be back to closed networks except this time the government does not have the balls to split any of the mega-corporations.
