It doesn't scale or do 24/7 power like fission/fusion would. Not sure why everyone is still against nuclear but that's fine too. I certainly have nothing against solar or wind and think we need a mix.
> But it will implode the blue collar dev job market eventually.

There is no “blue collar dev job market”, and the end of the dev kob market that has a hint of a bluish tinge in the collar is the end that is continuously being by tooling progress. But that just expands the scope to which it is useful to apply software development, increasing jobs and wages in software.

> ML will (eventually) be able to generate biz logic code, and most assuredly infrastructure config (a cloud API has a limited set of possible configs of value to our sorting patterns), UI code (we gravitate towards a limited set of UX it seems), to solve much of our daily programming work.

Its not “machine learning”, but we already have tools that develop code in all of those domains from higher-level descriptions that what previous generations of coders supplied to them. And each generation of that tooling just serves as a progressively greater output multiplier on time devoted to developing software.
Yeah I seem to recall that many extremely high voltage long distance lines are actually DC
One major difference though: it sounds like this Google Voice trash button is permanent, whereas Sheets has an undo button. I'm not a designer, but isn't this like design 101? Permanent action -> dialog box required.
Yeah, this is a huge myth I hear repeated all the time. AC won because losses are lower at higher voltage and yes, AC transformers (which are necessitated by high voltages) are easy to make.
We kept getting rejected by a reviewer who couldn't log in (we'd attached credentials to our submission). When they finally sent a screenshot with the rejection, it turns out they were using 'login with Google' and then entering the credentials we gave them there. Needless to say, they needed to use 'login with username/password'.
You can import any node module and use it with imba syntax. I’ve never had a problem doing this.
I’m fine blaming both. A poor platform doesn’t excuse toxic behavior.
So, I used to be "team DC" as well, but after learning up a bit, I realized there are still a lot of advantages to AC in the 21st Century.

One reason DC power is more viable nowadays is (as others here have mentioned) the use of DC-DC converters. They internally actually use AC to do the conversion (usually at much higher frequency to save weight and cost on inductive elements). But they're not super cheap (not cheaper than transformers) and they can also be inefficient.

But part of my problem with this article is it kind of sandbags the efficiency. We can get pretty high efficiency inverters and rectifiers. >90% is common and 95-98% is feasible (and not uncommon). Low voltage DC (like 12V) requires MUCH thicker cables for the same power, which means a lot more copper (and copper mining). Typical line voltage can be very lightweight.

With DC, nothing is really at the same voltage, so you need DC-DC converters all over anyway, so you're not saving anything (although not losing much, either!).

Another important thing that really drives some of the advantages is: breakers, relays, and (much less important) current measurements of existing cables. All these are feasible for both DC and AC, but cheaper and easier with AC. AC is self-extinguishing as it crosses zero 120 times a second. That means you can switch a circuit on or off when the applied voltage is very low, meaning you can use cheaper and lighter power electronics. Plus, at a given voltage, there's a safety advantage as arcs will more easily stop with AC.

I actually think it's funny to see this in a "low tech" blog. DC ubiquity is something really only practical for significant use (i.e. beyond automotive or RV) with modern 21st century power electronics.
Swiss Scientists Just Broke the Record for Calculating Pi
Rachel's posts have a thin veneer of pseudo-anonmyization that makes it not blatantly obvious which company each story is from, but I can vouch for a decent number of stories being basically spot on what happened (with a little bit of editorializing around the why things happened the way they did).
Totally agreed. Still kudos to the Lemon team in trying to improve the overall AWS experience.

What I'd love is a standardized DC outlet wired into homes that can power anything from a phone to a desktop computer.
I would love 12VDC wired around my house with step down converters for each room. It would allow Our kids to plug in and unplug most of their things themselves (music players, lights, etc).
In some cases, they are paid to do so because their disinformation serves to cause death to an enemy population. Whether they're themselves aware that they're doing this, or not, isn't important to the outcome.

It is worth a lot of money to somebody, to have people explaining (rationally or hysterically) why the cure to the disease will actually turn you to a chimpanzee, implant you with microchips, kill you directly, or make you be a crawling surrender weasel doing meaningless things to appease the libs.

It's worth a LOT of money to keep this pandemic alive and mutating. It has direct benefit… to somebody.
Indeed. This is because you get phase differences (due to finite speed of signal in wire, even though it's near c) over those distances. Converting to DC and then back to AC at the destination avoids any concern about phase mismatch.
> Your argument about non-starter is clearly incorrect, since Vulkan did result from it all.

I’m talking about what people perceived in 2013. You are welcome to judge people’s decisions, using your knowledge of future events, if that’s what you really want to do.

> Where were Apple and MS when this was happening between 2013 and 2016?

Apple and MS were thinking, correctly, “I bet I can deliver a working API before this committee with representatives from a dozen different companies with competing interests can get off their butts and even figure out what they’re going to name the project.”

Those years were years of massive, massive growth for the App Store and the iOS ecosystem. If you could fix major problems that your customers a couple years faster, during a time when sales were growing 50% year over year, you’d want to do it yourself too. There’s only so many engineers at your company with the patience and drive to sit on committees.

> Khronos was already managing OpenGL so they fit the role of overseeing it.

It was called “OpenGL Next”, not Vulkan, at the time. Well, not when Metal was released, since it didn’t even exist when Metal was released.
sure but zillow needs to find someone else to sell to, and that someone is likely getting a government backed mortgage
Really? Java has the best syntax out there. It's consistent and very easy to read unlike Go, Rust or the modern languages these days
I used to do electrical work when I was younger for my dad's company. The innovations in the blue color field might seem trivial but they are absolutely real.

Just the transition to modern romex with push in receptacles saves tons of time and effort in the part of the job you spend 90% of the time doing.

It's still manual labor but it's much less strenuous than it used to be and it's also much more efficient.
Quite sad to hear this. Intel has been pushing affordable very decently performing well integrated systems at a wide variety if form factors for a while.

lack of success is a scary indicator to me, indicating not much of a consumer market. most vision folk being eilling to either go off on their own & build solutions, or find higher budget offerings, indicates a kind of missing middle versus the pi-cam crowd (eho has nowhere near the great 3d chops Intel packages up).

Isn't that the whole point? Seems like these people don't understand open source and they want to take over his "baby" rather than going out and making their on even though they can clone his in under a minute and change it to their liking and own sphere of influence.
If an app which supports groups video calls counts as a "video conferencing platform" in your book, then you're better off using either Facetime or Signal, both of which support E2EE, unlike Telegram.
It's not "incorrect". They literally explain the reason why they say it is so in the very next sentence. Only taken out of context does it appear incorrect.
At least in both situations there Sheets allows you to undo the delete, so the closeness to other commands isn't so lethal. I've got no UX or UI training, but I gotta imagine that it'd be a basic rule that delete actions must always include a confirmation request or an undo option. In Voice, the lack of both confirmation and undo is just ludicrous.
We actually don't know any of those things. The situation, more accurately stated, is that a lot of people have excessive certainty about those things.

Correct. But currently, as far as is known, they actually do provide it. Which, practically, is what matters because other than WebEx there are no comparable alternatives that I'm aware of.
Yeah Purism is facing a two sided problem. Solving for privacy and Linux quality. It follows then that every System76 purchase helps a healthy Linux ecosystem AND enables others like Purism to push it even further. For Purism to win the marketplace needs System76 to win as well.

Ouch on those issues though. That would be roughto work with random shutdowns. This is good intel.
When most people think of NYC they think of Manhattan or the five boroughs, not the greatest metro area. But if you say the city of Miami you general mean the metro area. So it is just missing is all.
There's a flagged dead reply to this that attacks me. I think the author has missed the point and the point isn't very important anyway. I agree totally that the author of this or any other freely available material owes me nothing. Nor do I owe them.

persecuting gays

This is a perfect case of an actual disinformation. There's no persecution of gays in Russia. There's no law for persecuting gays, there's no actual persecution happening.

There's at least one openly gay bar in every major city, operating for years and everyone knows about them. Nobody cares.

Just a few days ago I've seen two girls carrying LGBT flag on a street of a small Russian town. Nobody cared (although they obviously wanted attention).

Only gay propaganda is disallowed in Russia, but it's not the same as "persecuting gays".
Yeah I think the argument the administration made is a retcon and they made decisions based on bad intelligence that the government would hold up long enough to get everyone and everything out. This idea that their government made a bad suggestion and we listened is silly — they were essentially a puppet state so it’s on us either way.
Using Microsoft's Jview JVM COM-Java integration (this is like '98 time frame) you could more easily run VB 6 apps against Java application servers because you only needed to distribute the client jar to the VB app. Since there was no early binding you didn't need the code you were going to call remotely on the client, it could just download the classes at runtime and use reflection to make the required calls. Drastically reduced any sort of jar/dll hell.
Helpful to know about the XPS bugs. Sounds odd, with Apple I've grown so used to not having issues like that.
Sounds like it works a little differently on Linux.

To be honest, I'm actually surprised and impressed that they support screen share in the Linux version because of how many different flavors of i.e. WM there are in the wild.
It's also a bit of a shame not to mention, in this context, that Vlad Țepeș is commonly used today as a symbol of law and order and anti-muslim sentiment by the (relatively weak) fascist sympathizers in the country.
Exactly there is nothing stopping them from taking mastodon source code and making their own little hate parade off in another niche of the internet. Basically "your rights end at the tip of your nose" when it comes to what I want on my own network.
Here's where this is confusing (to me at least).

The dimensionality of a vector space is the number of scalars needed to build a vector in that space. That's easy.

I also think of "rank" as synonymous with "dimensionality" but it's not. Or at least it implies a different connotation of the word "dimensionality." It's the number of dimensions in the notation rather than in the space. Or something. And now I'm off the rails. And this is before I start trying to think about a basis being "ordered pairs of vectors" or tensor fields or about how tensors transform.
This is one of the few times that I agree with Facebook and TikTok on their decision to ban content.
I don't see how this is possible. The building I live in cost about $100M in construction fees and has 200 apartments. If we make a dumb assumption that they all cost the same amount, thats $500k per apartment on just cost of building before any kind of supply and demand affects the final sales price. These apartments sold new for $600k and I rent one for $480 a week. (All Australian dollars)

Currently I would comfortably put $20,000 in to housing as an asset. I can not see any way possible that banning rentals would allow me to buy a $500k construction cost apartment for $20k.

So this change forces me to invest in a market I do not want to invest in to. Buying one of these apartments is an incredible risk as it will likely devalue over time and be difficult to sell on when I want to move. So every time I move under this system I am risking massive losses Vs just having a weekly price and no commitment or risk.
As with most sweeping generalizations, it's not the same person making all of those points. It's possible to hold one of those views each and have a large group with contradictory interests.
This doesn't sound right. The pipeline would be longer than the Alaska Pipeline, but carry a commodity that retails for 3 2-3 cents per gallon, not $3.50.
> Regarding home sales, Zillow generally pulls from local MLS databases, so unless it's for-sale-by-owner they tend to have all available homes. For home rentals, it'll be more fragmented.

Can they even do that? My understanding is the local MLS databases are the closely guarded pet of "Realtors™". I was told that Realtors will always list on the MLS, and may or may not list on Zillow as a separate process, depending on if they think it's necessary.
Don't Make Me Think is an excellent book.

USA English and British English are normally distinct in sites that support lots of languages. I think that Australia inherited things like British spelling and is the same? Or are there differences? (Color vs Colour, etc)
Exactly it's why I send money to ACLU and EFF. I'll spend money to help defend your right to say what you want, but I'll be damned if I have to listen to your BS on my own time. I'm just there to stop the government from outlawing freedom of speech.
Russia's methods of controlling the social media are, shall we say, a leetle bit different from that of China…

I think one could make a pretty good case that Russia has indeed controlled social media to their benefit. Not tracelessly, but to a really impressive extent. Pity they choose to do with it, what they've done.
Connect a hefty DC power supply to a power strip and just use that? Get a power strip of some obscure country for your DC so that you don't accidentally mix up 120VAC appliances with it.
> Java has the best syntax out there

De gustibus non est disputandum

> It's consistent and very easy to read unlike Go, Rust or the modern languages these days

Eh, its Algol-style syntax with a bunch of unique flourishes, like...lots of popular languages. Its nothing special, but its not especially consistent.

If your experience is heavily in Java, then it is probably particularly consistent (with your experience) and readable to you, but it doesn't seem to have any features that make it more of either of those than most popular languages in any general, not-experience-dependent, sense.
"Early DC power stations had a dynamo for every light bulb. Source unknown."

I have no idea where they got that picture either. Edison's Pearl St. station did not work that way, and that was the first power station. The generator shown is Edison's famous "long-waisted Mary Ann". But Edison never built a one generator per bulb power station. He was able to calculate ROI [1]. This is probably some conceptual drawing of what would have been necessary had the "subdivision of the electric light" (a hot issue around 1889)[2] had not been accomplished.

"In other words, a DC electrical system could make a solar PV system more energy efficient." Not clear that it matters much in terms of raw conversion efficiency. Solar inverters are now up around 96-98% efficiency. If you're going to have batteries, you need something that handles battery charging, discharging, and some constant output, and while you can get all that stuff for 12VDC or 24VDC, it's not any more efficient than outputting 120VAC.

The real argument they're making is to save power by using small boat or RV sized appliances. They're available, efficient, undersized, and about 3x as expensive as line-powered units.[3]

USB-C sucks, I break a USB-C cable a week. They're physically too weak. I've very rarely broken 120VAC plugs or cables.

Also you can't exactly have a USB-C PD power strip of 10+ plugs without it costing a fortune because of all the negotiation needed per-port. Now they're onto some GaN bullshit just to make the PD adapters smaller.

The standards are a shitshow, there are incredible number of non-compliant USB-C cables.

802.3at PoE is slightly better, you can get 24+ ports for a couple hundred bucks, most cables advertised to meet PoE specs do in fact meet them.

But really the best would be straight up 48V on 2 rails and a bunch of plugs. No negotiation, no bullshit, no GaN, just 2 wires. Equipment, cabling, power strips would be dirt cheap. Individual devices can have very compact, efficient buck converters to get the voltage they actually need.
If you revitalize economically depressed areas then there is less demand for housing in the hot areas thus precluding the need to build so much housing in those areas.

So focusing on building housing in the hot areas does not address the root cause.
I read the whole article with sympathetic interest, until the conclusion:

> One way to solve the problem of high power devices is simply not to use them -- this is the approach that's followed in sailboats, motorhomes and caravans

> Obviously, this strategy implies a change in our way of life. It would mean that electricity is used only for lighting, electronics and refrigeration, while non-electric alternatives are chosen for all other appliances. Not coincidentally, this is quite similar to how DC grids were operated in the late nineteenth century, when the only electric load was for lighting -- first arc lamps and later incandescent bulbs.

> Thus, no dishwasher, but doing the dishes by hand. No washing machine, but doing the laundry in a laundromat or with a manually operated machine. No tumble dryer, but a clothes line. No convenient and time-saving kitchen appliances like electric kettles, microwaves and coffee machines, but a traditional cooking stove operated by (bio)gas, a solar cooker, or a rocket stove. No vacuum cleaner, but a broom and a carpet-beater. No freezer, but fresh ingredients. No electric warm water boiler, but a solar boiler and a small wash at the sink if the sun doesn't shine. No electric car, but a bicycle.
USB Power Delivery 3.1 specifies power over USB-C up to 5A @ 48V. 240W doesn't give you a very powerful desktop: probably an SSD, a 65W CPU and a low power GPU. But that's still a decent desktop.

I don't necessarily think it's wise to do 5 amps over USB-C, but it is a standardized DC outlet. Personally, USB-A is still a more useful power outlet, but nobody is insane enough to shove 240W over it.
That's an unnecessary (inflammatory) diversion from the comparison, which is the core of the thread. I understand you want to elevate the conversation to what YOU feel strongly about, but posting it on impulse is not constructive.
Neither do the middle class. My property taxes as a home owner just keep going up and I don't really see anything in return for that from being in a growing city. I suppose I can sell my house for a tidy profit, but that's not why I moved here. I moved here for friends and the city as a platform to enjoy life.
Good rebuttal. I forget at times skilled trades are blue collar. Those people in this time are making a killing. My cousins are pipefitters, and make twice what I do as a 'Software Engineer', and I have no complaints, they deserve it.

I guess I was thinking of the lower tier blue collar laborers, where I had worked (landscaping, auto parts, etc) and especially 'pink collar', which I did not know existed until I googled it.
I'm 58 and it definitely seems worse. It could be that we're experiencing some level of ageism so that comparing with when we were younger it feels worse. I find it really depends on the workplace & people, though. Mostly it seems like I've had good experiences working in smaller companies than large corporations over the last decade. The two large corporations I worked for in during that period were not great experiences mostly due to managers not being good at managing people - stuff like micromanaging their whole team because they were very insecure and didn't trust any of their direct reports. I don't recall running into this level of distrust 20+ years ago.
I’m not sure if it’s satirical or not either, to be honest.

Plenty of Americans can walk a few miles. Besides, it’s not like rioting is something that doesn’t take significant cardio vascular fortitude in its own right. Something tells me that individually lots of those rioters were more than capable of walking five miles over level, paved terrain.

The real question is not whether or not a rioter could walk from there to here, but whether the riot will come here without being stopped or dissipating into smaller and easier to stop groups. If the riot disperses and 5% shows up at the other precinct, that’s a pretty easy thing for the cops to deal with; and if it isn’t I have questions about what all the public safety money is being spent for.

And that's of course before we look at the terrain. The 2nd and 3rd precinct are on opposite sides of the river. That means that even if you were certain that the riot was coming for the 2nd precinct next, you have a very small number of bridges that you could defend to stop the riot. In fact, cops regularly prefer bridges to kettle and mass arrest both riots and protests, and that would have been the perfect opportunity had it happened.
